• What are the requirements of Er spring collet for the specification of fixture workpiece?

  2020 / 03 / 18

  In the design scheme of Er spring collet, there are various types of workpieces, including metal stamping parts, aluminum profiles and components. Therefore, when designing the scheme, the allowable range of standard tolerance of workpiece clamping position should be estimated first. The application of spring collet can greatly improve the machining efficiency, and can maintain all machining surfaces of parts to be machined once clamped. According to the matching of round bar machine and cutting equipment, the whole process of automatic left and right material can be maintained, and finally intelligent manufacturing and continuous processing can be maintained. In such an application, the non drilling time saved for individual workpieces will be very micro analysis, but in the whole processing process, each workpiece reasonably arranges the time multiplied by the number of workpieces processed, and the total time saved is very rich. So what is the specification of Er spring collet to the fixture? 1. Especially suitable for small diameter workpiece processing. 2. The clamping time of workpiece is very short, which can keep the material around rapidly. 3. The removal and replacement time is very short, which can maintain the rapid removal and replacement of different specifications of tooling and fixtures. 4. Relative to chuck, the clamping precision is higher, and the coaxiality is stronger during turning processing. 5. Er can reduce the cost and coordinate better than chuck for special shape and boring sprin

  The spring chuck is a positioning device for prefabricated components that must be reformed for maintenance and engineering reinforcement. In the ordinary maintenance, the lathe spindle and the collet cone can be installed on the spindle bearing only after they are removed as far as possible. After application, the main body and pipe hoop should be removed clean and tidy, and rust proof, to ensure the smooth operation at that time. The following problems must be paid attention to in the maintenance of spring collet: The spring chuck is a positioning device for prefabricated components that must be reformed for maintenance and engineering reinforcement. In the ordinary 1. Before installing the main cone of the main shaft bearing, clean the cylinder collet cone and lathe main shaft, and use a rubber material hammer or mallet to slowly impact the internal thread of the body to ensure that it is closely connected, firm or tightened according to the engine crankshaft. 2. Before production and manufacturing, according to the specific production and manufacturing regulations, it is necessary to remove the sediment in the relative sleeve, put it into the main thread, push the main sliding cover lightly, make the sleeve square into the main inner square hole, and then clamp the relative numerical control tool on the sleeve, so as to produce, manufacture and use. 3. If you use the tapping effect, do you remember to let go of the nut first, and tighten the nut according to the takeout with different torque specifications, so that the tap cannot be dragged. 4. When putting the tap into the tap sleeve, pay attention t

  Handle structure There are two kinds of structural forms of tool shank in CNC machine tools: integral type and modular type. The working part of the clamping tool of the integrated tool handle is integrated with the handle for installation and positioning on the machine tool. This kind of tool handle has poor adaptability to the transformation between machine tool and parts. In order to adapt to the transformation of parts and machine tools, users must reserve various specifications of tool holders, so the utilization rate of tool holders is low. Modular tool system is a kind of advanced tool system, each handle of which can be assembled by a series of modules. According to different machining parts and machine tools, different assembly schemes can be adopted to obtain a variety of tool shank series, so as to improve the adaptability and utilization of tool shank. The selection of the structural form of the tool holder should take into account the advanced technology and reasonable economy: ① for some simple tools that are used repeatedly for a long time and do not need to be assembled, it is appropriate to equip with integral tool holder, so as to make the tool rigid and cheap (such as the end milling tool holder, spring head tool holder and drill chuck tool holder for machining the external contour of the parts, etc.); ② When machining many kinds and small batches of parts with varying hole diameter and hole depth, modular tool shank should be selected to replace a large number of integral boring tool shanks and reduce the processing cost; ③ modular tool shanks should be selected when there are many CNC machines, especially when the spindle end and tool changing manipulator are different. Because the intermediate module (extension bar) and working module (tool loading module) used
