Description

Technical Field

[0001] The utility model relates to the field of processing tooling, in particular to a quick clamping tooling for processing an eccentric shaft. Background Art

[0002] A workpiece whose outer circle is parallel to but not coincident with the axis of the outer circle is called an eccentric shaft. The eccentric shaft is generally fixed to the rotating shaft of the motor through an eccentric hole. When the motor starts, it performs cam motion. Therefore, it is widely used in automobiles, engines, pumps, etc. In mechanical transmission, the conversion of rotary motion into reciprocating linear motion or reciprocating linear motion into rotary motion is generally accomplished by using eccentric parts.

[0003] At present, a special clamping device is used in the processing of eccentric shafts, but workers are required to assist in positioning when fixing the workpiece, which takes a certain amount of time to manually adjust according to the size of the workpiece, thus affecting the work efficiency of the eccentric shaft processing clamping tooling.

[0004] Therefore, since the above-mentioned eccentric shaft clamping device requires workers to assist in positioning when fixing the workpiece, and it takes a certain amount of time to manually adjust according to the size of the workpiece, a quick-holding tooling that can automatically position can be designed. Utility Model Content

[0005] In order to overcome the problem that the eccentric shaft clamping device requires workers to assist in positioning when fixing the workpiece, it takes a certain amount of time to manually adjust according to the size of the workpiece.

[0006] The technical solution of the utility model is: a quick clamping tool for eccentric shaft processing, including a processing table, a support frame is fixedly installed on the rear side of the upper end of the processing table, a mounting tube is fixedly installed on the support frame, a telescopic cylinder is fixedly installed on the surface of the mounting tube, the output end of the telescopic cylinder extends to the inner side of the mounting tube and a clamping cylinder is fixedly installed, the front and rear ends of the clamping cylinder are fixedly installed with auxiliary slides, a slide groove is provided on the auxiliary slide, and auxiliary fixing parts are fixedly installed on the front and rear ends of the mounting tube, a waste trough is provided on the front side of the upper end of the processing table, an electric telescopic rod is fixedly installed on the side of the waste trough inside the processing table, the output end of the electric telescopic rod extends to the inner side of the waste trough and a connecting partition is fixedly installed, a receiving plate is provided on the inner side of the connecting partition, and a movable partition is provided at the front end of the waste trough.

[0007] Preferably, the support frame is designed in a U-shaped structure, and an anti-slip sleeve is fixedly installed on the surface of the clamping cylinder. The anti-slip sleeve increases the friction force on the surface of the clamping cylinder, making the clamping cylinder more stable when clamping the fixed eccentric shaft.

[0008] Preferably, the telescopic cylinders are distributed in a ring array, and the output ends of the telescopic cylinders are slidably connected to the mounting tubes.

[0009] Preferably, the auxiliary fixing members are distributed in a ring array, and the auxiliary fixing members are slidably connected to the sliding grooves.

[0010] Preferably, the output end of the electric telescopic rod is slidably connected to the processing table, the connecting partition and the receiving plate are adapted to the waste trough, and the telescopic distance of the electric telescopic rod is adapted to the front and rear widths of the waste trough to avoid the connecting partition moving too far or too long, affecting the normal movement of the receiving plate.

[0011] Preferably, the connecting partition is designed to have a U-shaped structure, and the rear end of the receiving plate is rotatably connected to the connecting partition.

[0012] Preferably, the upper end of the movable partition is rotatably connected to the processing table, and the front end of the processing table is located on the lower side of the movable partition and is fixedly installed with a protective pad. The protective pad provides protection and support for the flipped receiving plate to avoid direct impact on the processing table, and forms a certain support angle to facilitate the recovery of the receiving plate.

[0013] Beneficial effects of the utility model:

[0014] 1. This quick clamping fixture for eccentric shaft processing uses a telescopic cylinder to drive the clamping cylinder and anti-slip sleeve to move inward, and cooperates with auxiliary fixing parts and auxiliary sliding parts to maintain the stability of the clamping mechanism until the clamping cylinder and anti-slip sleeve fit tightly against the eccentric shaft, completing the automatic positioning and clamping of the eccentric shaft, eliminating the need for workers to manually adjust according to the size of the workpiece, which is conducive to improving the working efficiency of the eccentric shaft clamping device;

[0015] 2. The quick clamping tooling for eccentric shaft processing collects processing waste through the connecting partition and the receiving plate inside the waste trough. When cleaning is required, the connecting partition and the receiving plate are driven forward by the electric telescopic rod, and the connecting partition is used to push the movable partition. When the receiving plate is completely moved out of the waste trough, the receiving plate loses its bottom support and thus flips downward, causing the processing waste to automatically slide out to complete the cleaning work. Finally, the connecting partition and the receiving plate are retracted, which is conducive to improving the convenience of waste cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

First, one end of the eccentric shaft is extended into the inner side of the mounting cylinder 3, and the telescopic cylinder 4 is used to drive the clamping cylinder 5 and the anti-slip sleeve 14 to move inward, and cooperate with the auxiliary fixing parts 8 and the auxiliary slide 6 to maintain the stability of the clamping mechanism until the clamping cylinder 5 and the anti-slip sleeve 14 are tightly fitted to the eccentric shaft, completing the automatic positioning and clamping of the eccentric shaft, avoiding manual adjustment by workers according to the size of the workpiece, and helping to improve the working efficiency of the eccentric shaft clamping device.
