[0002] A metal casing, serving as the outer layer covering an object or device, is primarily made of metallic materials.

[0003] Currently, when processing metal shells, metal clamping blocks are often used in conjunction with lead screws to achieve the clamping effect. However, in actual use, due to the thinness of some metal shells, the clamping force of traditional clamping mechanisms is relatively concentrated, which can easily cause deformation and damage to the metal shells. Therefore, there is an urgent need for a fixture for processing metal shells. Utility Model Content

One end of each clamping block is connected to a screw clamping mechanism. Extension blocks are mounted on both sides of each clamping block. A guide plate is provided on the inner wall of each extension block. The guide plate extends into the clamping block and is correspondingly limited to the guide block. The guide block is installed inside the clamping block via a screw.

[0007] Furthermore, in a preferred configuration, the lead screw clamping mechanism includes a lead screw, a sleeve, and a connecting seat. The lead screw is screwed to the mounting plate, and one end of the lead screw is fixedly connected to the clamping block, while the other end passes through the connecting seat and is screwed to the sleeve.

[0008] Furthermore, a preferred configuration is that the sleeve is provided with a handle for gripping and rotating.

[0009] Furthermore, in a preferred configuration, the sleeve is rotatably mounted on the connecting seat.

[0010] In addition, a preferred structure is that the upper part of the clamping block is provided with an adjustment head, one end of which is connected to the second lead screw, one end of which is rotatably installed on the inner bottom wall of the clamping block, and a guide plate is screwed onto the second lead screw, the guide plate being triangular in shape.

[0011] In addition, a preferred structure is that one end of the extension block is equipped with a plurality of guide rods, one end of the guide rods extends into the inside of the clamping block, and a spring is installed between the head of the guide rod and the inner wall of the clamping block.

[0012] In addition, a preferred structure is that a plurality of guide rods are installed on one side of the clamping block, and the guide rods are guided and connected to the mounting plate.

[0013] In addition, a preferred structure is that the guide plate has a right-angled trapezoidal cross section, and a guide groove is provided in the middle of its inclined surface, with a guide block slidably installed in the guide groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, by adjusting the adjusting head on the upper part of the clamping block, the guide block inside the clamping block is driven to squeeze and push the extension block assembly, thereby increasing the overall clamping area of ​​the fixture on the workpiece, making the clamping force more uniform and dispersed, thus effectively avoiding damage to the workpiece surface and improving processing efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5A metal casing processing fixture includes a frame 1. A pair of clamping blocks 4 are symmetrically mounted on the upper part of the frame 1 via a mounting plate 2. One end of the clamping block 4 is connected to a screw clamping mechanism. Extension blocks 5 are mounted on both sides of the clamping block 4. A guide plate 11 is provided on the inner wall of the extension block 5. The guide plate 11 extends into the clamping block 4 and is correspondingly limited and connected to the guide block 13. The guide block 13 is limited and installed inside the clamping block 4 via a screw 121.

[0024] Furthermore, the screw clamping mechanism includes a screw 3, a sleeve 7, and a connecting seat 8. The screw 3 is screwed to the mounting plate 2, and one end of the screw 3 is fixedly connected to the clamping block 4, while the other end passes through the connecting seat 8 and is screwed to the sleeve 7.

[0025] Furthermore, the sleeve 7 is provided with a handle for gripping and rotating.

[0026] Furthermore, the sleeve 7 is rotatably mounted on the connecting seat 8.

[0027] Furthermore, an adjustment head 12 is provided on the upper part of the clamping block 4. One end of the adjustment head 12 is connected to the lead screw 121. One end of the lead screw 121 is rotatably installed on the inner bottom wall of the clamping block 4, and a guide plate 11 is screwed onto the lead screw 121. The guide plate 11 is triangular.

[0028] Furthermore, a plurality of guide rods 9 are installed at one end of the extension block 5. One end of the guide rods 9 extends into the clamping block 4, and a spring 10 is installed between the head of the guide rod 9 and the inner wall of the clamping block 4. The spring 10 is used to realize the reset function of the extension block 5 and improve the movement stability of the extension block 5.

[0029] Furthermore, multiple guide rods 6 are installed on one side of the clamping block 4, and the guide rods 6 are guided and connected to the mounting plate 2.

[0030] Furthermore, the guide plate 11 has a right-angled trapezoidal cross section, and a guide groove 111 is provided in the middle of its inclined surface. A guide block 13 is slidably installed in the guide groove 111.

[0031] In this embodiment, the screw 3 is driven by rotating the sleeve 7 to achieve the lateral clamping function of the clamping plate 4. The adjusting head 12 is rotated to drive the screw 121 to rotate synchronously. The screw 121 drives the guide block 13 to move vertically and squeezes and pushes the guide plate 11 assemblies on both sides. Under the influence of the squeeze and push, the guide plate 11 moves through the guide rod 9 and moves laterally in sync with the extension block 5, thereby expanding the overall clamping area on both sides of the clamping block 4.

[0032] In actual use, guide grooves 111 for limiting the movement are provided on both sides of the guide plate 11. The guide grooves 111 can effectively limit the two ends of the guide block 13 to ensure its smooth movement.

[0033] In this invention, by adjusting the adjusting head 12 on the upper part of the clamping block 4, the guide block 13 inside the clamping block 4 is driven to squeeze and push the extension block 5 assembly, thereby increasing the overall clamping area of ​​the fixture on the workpiece, making the clamping force more uniform and dispersed, thus effectively avoiding damage to the workpiece surface and improving processing efficiency.
