Abstract
Description
Technical Field
[0001] This utility model relates to the field of workpiece clamping fixture technology, and in particular to a square cutting fixture for rod-shaped workpieces. Background Technology
[0002] When using wire EDM to cut squares from a bar-shaped workpiece, the workpiece must first be clamped and fixed on the worktable, typically using a vise or similar fixture. After the first wire EDM cuts one square, the operator needs to rotate the rocker arm to release the workpiece from the vise, then rotate the bar fixture to a certain angle, and finally clamp the workpiece again with the vise for the second cut. The entire clamping process involves repeated tightening and loosening, as well as workpiece rotation. The clamping steps are numerous, and the workpiece rotation angle is difficult to control precisely. Each change in the cutting angle requires manual remeasurement and confirmation. Therefore, using conventional fixtures for square cutting is time-consuming, physically demanding for workers, and lacks precision. Utility Model Content
[0003] The purpose of this utility model is to provide a square cutting fixture for rod-shaped workpieces, so as to solve the problems that general fixtures have many clamping actions, which waste time, increase the labor intensity of workers, and result in insufficient processing accuracy when used for square cutting.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A square cutting fixture for rod-shaped workpieces includes a fixed plate, a rotating plate, a baffle, a clamping device, and a locking pin. The rotating plate is rotatably mounted in the circular cavity of the fixed plate. At least one first positioning groove is provided on the outer periphery of the rotating plate, and a second positioning groove that mates with the first positioning groove is provided in the circular cavity. The locking pin is slidably mounted in the locking cavity formed by the first and second positioning grooves. The baffle is mounted on the side of the fixed plate and abuts against the rotating plate. The clamping device is mounted on the rotating plate, and the working end of the clamping device is located in the workpiece cavity of the rotating plate, and the working end of the clamping device presses the workpiece.
[0006] A further technical solution is: the clamping device includes a bolt and a circular pressure plate, the bolt is threadedly mounted on the rotating plate, the circular pressure plate is rotatably mounted on the inner end of the bolt and located in the workpiece cavity, and the circular pressure plate abuts against the workpiece.
[0007] A further technical solution is that the bolt is inclined toward the center of the rotating plate.
[0008] A further technical solution is that both the circular cavity and the workpiece cavity are provided with notches.
[0009] A further technical solution is that a lever is provided on the rotating plate.
[0010] A further technical solution is that the fixing plate is provided with a groove for avoiding the clamping device and the lever.
[0011] A further technical solution is that a convex edge is provided between the fixed plate and the rotating plate to cooperate with each other.
[0012] A further technical solution is that fixing holes are symmetrically arranged on the outer side of the fixing plate.
[0013] A further technical solution is that the fixing hole has a structure that is smaller at the top and larger at the bottom.
[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:
[0015] This invention proposes a squaring fixture for rod-shaped workpieces. This fixture eliminates the need to change the squaring angle and re-clamp the workpiece after each clamping operation. Simply rotating the rotating plate changes the position and angle of the clamped workpiece symmetrically. The fixing and rotation of the rotating plate can be controlled by inserting and removing locking pins, making the process quick and efficient. In use, this squaring fixture facilitates workpiece clamping and ensures precise and reliable squaring angles, greatly guaranteeing smooth squaring and high-quality processing.
