High-precision adjusting and limiting mechanism for core rod cutting machining

Abstract

The invention provides a high-precision adjusting and limiting mechanism for core rod cutting processing, and relates to the technical field of core rod machining. The high-precision adjusting and limiting mechanism comprises a movable base, a top frame and arc-shaped springs, wherein the movable base is fixed to a cutting workbench through bolts and is of a groove-shaped structure, and a supporting plate is installed in the top of the movable base, a bottom frame is arranged at the top of the supporting plate, two clamping rollers are rotationally connected into the bottom frame, two clamping rollers are rotationally connected to the interior of the top frame, the top frame is connected to the bottom frame through a connecting rod, a driving rocker is connected to the front end of the top frame, and the arc-shaped springs are connected to the left and right ends of the bottom plate correspondingly. According to the high-precision adjusting and limiting mechanism, thrust is applied to the connecting rod through the arc-shaped springs according to different diameter specifications of core rods, the connecting rod drives the top frame to obliquely move downwards in a horizontal state so that the two clamping rollers inside the top frame can be pressed on the top sides of the core rods at the same time, the attaching tightness of the clamping rollers in the top frame and the top sides of the core rods is guaranteed, the core rods are clamped and fixed, and the core rods are clamped and fixed more simply and conveniently.

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
