Description

Technical Field

[0001] This utility model relates to a tooling fixture, specifically a fixture for processing the clamping arm of a cold heading machine. Background Technology

[0002] A part called a clamping arm is used on cold heading machines. Due to its irregular shape, after the casting or forging blank is formed, the top surface and two sides need to be milled first. Each workpiece needs to be carefully adjusted before milling to ensure accurate positioning so as to facilitate milling by the milling cutter. The work efficiency is low and it is not suitable for mass production. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a cold-bent machine clamping arm machining fixture for quickly milling the top surface and two sides of the cold-bent machine clamping arm, with high overall rigidity to ensure machining quality, suitable for mass production of cold-bent machine clamping arms.

[0004] This utility model is implemented through the following technical solution: A cold forging machine clamping arm processing fixture is characterized by comprising a left support and a right support. A power box is fixedly installed on the left support. The input of the power box is connected to a servo motor, and the output is connected to a left gravity plate. The left gravity plate is located on the right side of the power box. A support seat is fixedly installed on the right support. A right gravity plate is rotatably mounted on the support seat and is located on the left side of the support seat. A crossbeam plate is provided between the left and right gravity plates. One end of the crossbeam plate is fixedly attached to a right support step on the right end face of the left gravity plate, and the other end is fixedly attached to a left support step on the left end face of the right gravity plate. A rigid seat is formed between the left and right gravity plates and the crossbeam plate. A clamping body for positioning and clamping the cold forging machine clamping arm is installed in the middle of the crossbeam plate.

[0005] One side of the fixture body has a first boss, the first boss has a slot in the middle, and threaded holes are provided on both sides of the slot. The other side of the fixture body has a second boss, the top of the second boss is threaded to a locking block, and a positioning block is provided on the inner side of the second boss at the root position.

[0006] The clamp body is fixedly connected to the crossbeam plate by screws. Multiple rows and columns of mounting holes on the crossbeam plate correspond to the screw holes on the bottom plate of the clamp body.

[0007] The cold heading machine clamping arm processing fixture using the above technical solution has a clamping body structure that can quickly position and clamp the workpiece to be processed, ensuring accurate positioning of the workpiece on the milling worktable, so as to realize rapid milling of the top surface and two sides of the cold heading machine clamping arm. At the same time, the left and right gravity plates and the crossbeam plate form a rigid seat with high overall rigidity, which can avoid the influence of vibration during the processing and better ensure the processing quality. Therefore, it is very suitable for the mass production of cold heading machine clamping arms. Attached Figure Description

Detailed Implementation

[0010] As shown in the figure, the cold heading machine clamping arm processing fixture of this utility model includes a left support 1 and a right support 9. The left support 1 and the right support 9 are installed on the milling worktable. A power box 2 is fixedly installed on the left support 1. The input of the power box 2 is connected to a servo motor 3, and the output is connected to a left gravity plate 4. During operation, the servo motor 3 drives the left gravity plate 4 to rotate through a worm gear structure. The left gravity plate 4 is located on the right side of the power box 2. A support seat 8 is fixedly installed on the right support 9. A right gravity plate 7 is rotatably mounted on the support seat 8. The right gravity plate 7 is located on the left side of the support seat 8. A crossbeam plate 6 is provided between the right gravity plates. One end of the crossbeam plate 6 is fixedly attached to the right support step 41 on the right end face of the left gravity plate 4, and the other end is fixedly attached to the left support step 71 on the left end face of the right gravity plate 7. The left and right gravity plates and the crossbeam plate 6 form a rigid seat with sufficient rigidity to meet the processing requirements of the cold heading machine clamping arm. A clamping body 5 for positioning and clamping the cold heading machine clamping arm is installed in the middle of the crossbeam plate 6. The clamping body 5 is fixedly connected to the crossbeam plate 6 by screws. Multiple rows and columns of mounting holes 61 are installed on the crossbeam plate 6, corresponding to the screw holes on the bottom plate of the clamping body 5. The left side of the clamping body 5 has a first boss 51. The first boss 51 has a slot 53 in the middle. Threaded holes 54 are provided on both sides of the slot 53. The right side of the clamping body 5 has a second boss 52. The top of the second boss 52 is threadedly connected to a locking block 11. A positioning block 10 is provided at the root position on the inner side of the second boss 52.

[0011] The present invention works as follows: A blank 100 of the cold forging machine's clamping arm is placed on the clamping body 5. The lower left end of the blank 100 rests within the slot 53, while the foremost position of the right end is limited by the second protrusion 52. The positioning block 10 also limits the forked groove on the right end of the blank 100. After these actions are completed, two locking screws pass through the threaded holes on both sides of the slot 53 to tighten and fix the left end of the blank 100. At this time, the front and rear positions of the blank are adjusted by the different screwing lengths of the two locking screws to ensure accurate positioning. After these actions are completed, the screws are tightened... The locking block 11 clamps and fixes the right end of the blank 100; next, by moving the milling table, the milling cutter first mills the top surface of the blank 100, and then controls the servo motor 3 to rotate the rigid seat structure and the clamping body 5 on it 90 degrees in the forward and reverse directions. The milling cutter mills the left and right sides of the blank 100. After the processing is completed, the workpiece can be quickly loaded and unloaded, thereby realizing the rapid milling of the top surface and two sides of the cold heading machine clamping arm. The overall rigidity is high to ensure the processing quality, which is suitable for the batch processing and production of cold heading machine clamping arms.
