Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, specifically a clamping mechanism for hardware processing. Background Technology

[0002] When processing hardware, clamping devices are needed to clamp the hardware parts, and then the hardware parts are processed by cutting, grinding, scribing and other processes. Fixtures are usually used, but the posture of the hardware parts needs to be constantly adjusted during processing, so a clamping mechanism that is easy to adjust is required.

[0003] The existing patent, CN218364219U, entitled "A Clamping Mechanism for Hardware Processing," relates to the field of hardware processing technology and discloses a clamping mechanism for hardware processing. It includes a support with a fixing hole at its bottom. A second hydraulic push rod is rotatably connected to the rear top of the support. A top clamping assembly is connected to the output end of the second hydraulic push rod. A side clamping assembly is rotatably connected to the front top of the support. The top clamping assembly is sleeved on the outside of the side clamping assemblies and restricts their position. A support assembly is located on the front of the support, with its bottom coplanar with the bottom of the support. This clamping mechanism, by incorporating the top clamping assembly and the top clamping frame within it being pushed and tilted forward at the top of the guide rod, can apply force to the top of the workpiece, pressing it firmly against the support platform. The device is adaptable to clamping and fixing workpieces of different heights.

[0004] The aforementioned device, by providing a top clamping assembly and a top clamping frame within the top clamping assembly that can be pushed to tilt forward at the top of the guide rod, allows the metal processing clamping mechanism to apply force to the top of the workpiece and press it against the support platform. However, it is difficult to adjust the posture of the metal parts when they are clamped, and repeated clamping will increase the workload and processing errors, which cannot well meet people's needs. In view of the above situation, technical innovation is carried out on the basis of the existing clamping mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping mechanism for hardware processing to solve the problems mentioned in the background art.

[0007] Furthermore, the rotating assembly includes a gear and a locking block, with the locking block located on the right side of the gear, and the gear is welded to the upper adjustment frame for synchronous rotation.

[0008] Furthermore, the rotating assembly includes a button, a lever, and a spring. The spring is provided on the right side of the locking block, and the lever is rotatably connected above the locking block. The button is rotatably connected above the lever.

[0009] Furthermore, a pressure block is installed at the front end of the slider, and the pressure block is rotatably connected to the slider.

[0010] Furthermore, a connecting post is installed at the lower end of the connecting rod, and the connecting post is welded to the connecting rod, allowing the connecting rod to move up and down in the vertical groove via the connecting post.

[0011] Furthermore, a clamping groove is installed at the upper end of the connecting rod, and a right clamping plate is installed on the upper right side of the clamping groove.

[0012] Furthermore, a left clamping plate is provided on the left side of the right clamping plate, and an anti-slip pad is adhered to the inner side of the left clamping plate. The anti-slip pad prevents slippage during clamping, resulting in a better clamping effect.

[0013] Furthermore, a lead screw is installed inside the lower end of the left clamping plate, and the lead screw is threadedly connected to the left clamping plate. Rotating the lead screw causes the left clamping plate to move in the clamping groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the rotating screw pushes the fixing plate against the bottom of the worktable through the mounting plate to fix the device. Pressing the button causes the lever to lift the locking block, the gear is unlocked, and the upper adjustment frame can be rotated to adjust the orientation. After releasing the button, the spring resets the locking block to fix the gear and fixes the orientation of the adjustment frame. The connecting rod moves up and down in the vertical groove through the connecting column, and the slider moves synchronously. The connecting rod changes the tilt angle through the arc groove. The rotating pressure block presses against the surface of the arc groove to fix the tilt angle of the connecting rod. The rotating screw drives the left clamping plate to move in the clamping groove, clamping the hardware between the right clamping plate and the left clamping plate.

[0015] 1. In this utility model, the base plate is placed above the edge of the workbench, and the rotating screw is used to push the fixing plate against the bottom of the workbench through the mounting plate to fix the device. Pressing the button causes the lever to lift the locking block, the gear is unlocked, and the upper adjustment frame can be rotated to adjust the orientation.
