A high-precision adjustment limit mechanism for mandrel cutting

Abstract

The invention provides a high-precision adjustment limit mechanism for mandrel cutting, which relates to the technical field of mandrel processing, and includes a movable seat, a top frame and an arc spring; the movable seat is fixed on the cutting table by bolts, and the movable seat It is a groove-shaped structure, and the support plate is installed in the top of the movable seat; the top of the support plate is provided with an underframe, and the inside of the underframe is rotatably connected with two pinch rollers; the inside of the top frame is rotatably connected with two pinch rollers , and the top frame is connected to the bottom frame through a connecting rod, and the front end of the top frame is connected with a driving rocker; the arc springs are respectively connected to the left and right ends of the bottom frame. According to the difference in mandrel diameter specifications, the present invention applies a thrust to the connecting rod through the arc spring, and the connecting rod drives the top frame to move downwards in a horizontal state, so that the two clamping rollers inside the top frame can be pressed on the top of the mandrel at the same time. side, to ensure the tightness of the clamping roller inside the top frame and the top side of the mandrel, to realize the clamping and fixing of the mandrel, and to make the clamping and fixing of the mandrel easier.

Description

technical field [0001] The invention belongs to the technical field of mandrel processing, and more specifically relates to a high-precision adjustment limit mechanism for mandrel cutting. Background technique [0002] The mandrel refers to the part of the mold used to form the contour surface in the compact or sintered body in the pressing direction. When the mandrel is manufactured and processed, it is necessary to cut the length of the mandrel by cutting equipment according to the needs of production and use. In order to ensure Cutting accuracy, which usually needs to be adjusted with high precision. [0003] The adjustment and limit mechanism for mandrel cutting can refer to patent CN109773267B, which mainly includes a frame, a feeding device, a clamping device, a moving device, and a cutting device. The top of the frame is sequentially equipped with a feeding device from back to front , the clamping device and the moving device that can realize the feeding and retracti...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a high-precision adjustment and limit mechanism for mandrel cutting processing to solve the problem that the existing similar mandrel cutting and processing adjustment and limit mechanism has low adjustment accuracy for the mandrel during the application process. During the mandrel cutting operation, the mandrel itself is prone to displacement, which affects the cutting accuracy of the mandrel, and can only achieve vertical cutting of the mandrel, and it is difficult to adjust and fix the angle of the mandrel according to the cutting requirements of different inclination angles of the mandrel , using the more restrictive problem
