Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a machining fixing mechanism. Background Technique

[0002] Machining refers to the process of directly changing the shape, size, relative position, properties, etc. of a blank by mechanical machining methods to make it a qualified part. The machining process directly determines the quality of parts and mechanical products, and has a greater impact on the cost and productivity of products. During the machining process, the workpiece needs to be fixed by a fixture to improve the stability of the workpiece during machining.

[0003] When machining some shaft-like parts or small discs, a horizontal machine tool can be used for machining. Fix it on the fixture, and then start the machine tool to perform turning machining with a turning tool. However, the traditional machine tool loading is very inconvenient, the process of clamping profiles is complex, time-consuming and laborious. A professional wrench is needed to lock the fixture of the machine tool to fix the profiles, and quick disassembly and quick installation cannot be achieved. The traditional method of fixing workpieces is fixed by four pressing plates at the four corners. This fixing method has low efficiency, the workpiece is prone to deformation, and pressing plate marks will be left on the workpiece; there is also a traditional side fixing method that uses screws to side-press. This method will cause the workpiece to warp upwards. Therefore, a machining fixing mechanism is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3, a processing and fixing mechanism in this embodiment includes a workbench 1. A cavity 2 is opened inside the workbench 1. A bidirectional motor 3 is fixedly installed inside the cavity 2. First threaded rods 4 are fixedly connected to both the left and right sides of the bidirectional motor 3. Moving blocks 5 are arranged on the outer surfaces of the first threaded rods 4. Fixing structures 6 are arranged on the adjacent sides of the two moving blocks 5. The fixing structure 6 includes clamping plates 601, second threaded rods 602, rotating rods 603, connecting blocks 604, connecting rods 605, clamping rods 606, hinge blocks 607, connecting rods 608, springs 609, and pressing plates 610. Clamping plates 601 are fixedly installed on the tops of the moving blocks 5. Second threaded rods 602 are threadedly connected to the sides of the two clamping plates 601 away from each other. Rotating rods 603 are rotatably connected to the adjacent sides of the two second threaded rods 602. Connecting blocks 604 are arranged on the adjacent sides of the two rotating rods 603. Connecting rods 605 are hinged to the front and rear sides of the two connecting blocks 604. Two clamping rods 606 are fixedly installed on the inner walls of the adjacent sides of the two clamping plates 601. Hinge blocks 607 are fixedly installed on the adjacent sides of the two groups of clamping rods 606. Connecting rods 608 are arranged on the adjacent sides of the two groups of clamping rods 606. Springs 609 are sleeved on the outer surfaces of the two groups of connecting rods 608. Pressing plates 610 are fixedly installed on the adjacent sides of the two groups of connecting rods 608.

[0023] As Figure 1 and Figure 2 shown, two chutes are opened on the top of the workbench 1. The two moving blocks 5 and the two first threaded rods 4 are in a threaded connection. When the bidirectional motor 3 drives the two first threaded rods 4 to rotate, the two moving blocks 5 move on the outer surfaces of the two first threaded rods 4.

[0024] As Figure 1 and Figure 2 shown, the tops of the two moving blocks 5 extend to the outside of the workbench 1 through the two chutes. The front, rear sides of the two moving blocks 5 and the inner walls of the front, rear sides of the two chutes are in a sliding connection. The two chutes keep the two moving blocks 5 stable, preventing the two moving blocks 5 from rotating when the two first threaded rods 4 rotate, and enabling the two moving blocks 5 to only move.

[0025] As Figure 2 and Figure 3 shown, the adjacent sides of the two rotating rods 603 and the sides of the two connecting blocks 604 away from each other are in a rotatable connection. The adjacent sides of the two groups of connecting rods 605 and the two groups of hinge blocks 607 are in a hinged connection. When the two second threaded rods 602 are rotated, the two second threaded rods 602 move away from each other, and the two rotating rods 603 move, driving the two connecting blocks 604 to move.

[0026] As Figure 2 and Figure 3As shown, both sets of connecting rods 608 are slidably connected to both sets of clamping rods 606. The sides of the two springs 609 facing away from each other and the adjacent sides of the two sets of clamping rods 606 are fixedly connected. A connecting block 604 drives the movement towards the sides away from each other, pulling the two connecting rods 605 towards the sides away from each other, and the two sets of clamping rods 606 shift towards the adjacent sides.

[0027] As Figure 2 and Figure 3 shown, the sides of the two springs 609 facing away from the two pressing blocks 610 are fixedly connected. Rubber pads are fixedly installed on the adjacent sides of the two sets of pressing blocks 610. The two sets of pressing blocks 610 clamp the parts. The two sets of connecting rods 608 move towards the sides away from each other, compressing the two springs 609, fixing the parts between the two sets of pressing blocks 610, and the two rubber pads protect the mechanical parts from scratches.

[0028] During implementation, the operations are carried out in the following steps:

[0029] 1) First, start the bidirectional motor 3 to move the two moving blocks 5 towards the adjacent sides.

[0030] 2) Then, place the part between the two clamping plates 601 and rotate the two second threaded rods 602.

[0031] 3) Next, pull the two connecting rods 605 towards the sides away from each other, causing the two sets of clamping rods 606 to shift towards the adjacent sides, and the two sets of pressing blocks 610 clamp the part.

[0032] 4) Finally, the two sets of connecting rods 608 move towards the sides away from each other, compressing the two springs 609, and fixing the part between the two sets of pressing blocks 610.

[0033] In summary, for this processing and fixing mechanism, by setting the fixing structure 6, when fixing a mechanical part, start the bidirectional motor 3, the two first threaded rods 4 rotate, driving the two moving blocks 5 to move towards the adjacent sides. Subsequently, place the part between the two clamping plates 601, then rotate the two second threaded rods 602, the two second threaded rods 603 move towards the sides away from each other, driving the two connecting blocks 604 to move towards the sides away from each other, pulling the two connecting rods 605 towards the sides away from each other, causing the two sets of clamping rods 606 to shift towards the adjacent sides, the two sets of pressing blocks 610 clamp the part, the two sets of connecting rods 608 move towards the sides away from each other, compressing the two springs 609, and fixing the part between the two sets of pressing blocks 610, thereby completing the fixing function of the mechanical part.
