Description

Technical Field

[0001] This utility model relates to the field of magnetic pad technology for clamps, and in particular to a rotating magnetic pad structure for clamps. Background Technology

[0002] In the fields of stamping and injection molding, workpiece clamping mechanisms are core components that ensure production accuracy and efficiency. Their technological development has always revolved around automation, stability, and adaptability. Early clamping equipment mostly relied on manual operation, using mechanical jaws or bolts to fix workpieces. With the advancement of industrial automation, pneumatic and hydraulically driven clamping systems have gradually become popular, enabling rapid opening and closing and force control adjustment to adapt to the processing needs of workpieces of different materials and shapes.

[0003] As a key component for protecting the workpiece surface and adjusting the clamping gap, shims are currently generally placed manually. Operators need to accurately place the shims in the clamping position before clamping the workpiece. However, due to factors such as visual errors, operator fatigue, or limited tooling space, errors such as shim misalignment, omission, or stacking are very likely to occur. Such placement deviations directly lead to a reduction in the contact area between the fixture and the workpiece and uneven force distribution. Under the high-frequency vibration and high pressure of stamping or injection molding, the shims are prone to loosening and falling out of the clamping gap. Moreover, shim detachment may also cause workpiece positioning failure, resulting in quality problems such as out-of-tolerance machining dimensions and surface scratches. In severe cases, it may even damage the mold or equipment, increase downtime maintenance costs, and restrict the continuous and stable operation of the production line. Utility Model Content

[0004] In order to overcome the problem that the workpiece clamping mechanism of the existing stamping and injection molding equipment is prone to incorrect placement of the gasket during manual placement, resulting in decreased contact stability with the clamp and causing the gasket to easily loosen and fall off during the processing of the workpiece, this utility model provides a rotating magnetic gasket structure for the clamp.

[0005] The technical solution is as follows: The rotating magnetic pad structure of the clamp includes a clamp assembly, a lever adjustment assembly, and a magnetic pad assembly; the lever adjustment assembly is provided inside the clamp assembly; the magnetic pad assembly is provided at the front end of the clamp assembly; the clamp assembly includes a clamp base; the clamp base has an assembly threaded hole inside, and the assembly threaded hole is integrally formed with the clamp base; a height adjustment column is provided inside the assembly threaded hole; a top post is fixedly provided inside the height adjustment column; a clamp lever is provided at the upper end of the top post, and the clamp lever is rotatably connected to the clamp base; a magnetic pad is provided in front of the clamp lever; connecting rods are provided at both ends of the rear of the magnetic pad; and sliders are provided on the outside of the connecting rods.

[0006] Furthermore, there are four connecting rods, which are fixedly connected to the magnetic pads; there are two sliders; each slider has a return spring at its rear, which is sleeved on the outside of the connecting rod; a spring nut is provided at the rear end of the return spring, which is fixedly connected to the return spring and threadedly connected to the connecting rod.

[0007] Furthermore, each slider has a screw inside, and the screw is fixedly connected to the slider with a bolt. The two screws are inserted into the front sides of the clamp lever and rotated to connect.

[0008] Furthermore, the slider is slidably connected along the axis of the connecting rod.

[0009] Furthermore, when the magnetic pad rotates to the bottom of the clamp lever, the return spring is in a compressed state; when the magnetic pad rotates to the front of the clamp lever, the return spring is in a stretched state.

[0010] Furthermore, height adjustment holes are provided around the height adjustment column, and the height adjustment holes are integrally formed with the height adjustment column.

[0011] Furthermore, the height adjustment post is threadedly connected to the assembly threaded hole.

[0012] The beneficial effects are as follows: This utility model achieves a dynamic connection structure between the magnetic pad and the clamp lever by rotating the magnetic pad horizontally or downward 90 degrees along the front end of the clamp lever. The magnetic pad is rotatably connected to both sides of the front end of the clamp lever by the screw pin inside the slider. With the slider sliding along the connecting rod and the elastic action of the return spring, the magnetic pad can always be in close contact with the front end and lower end of the clamp lever when rotating around the screw pin axis. This avoids the displacement and poor contact that usually occur when the magnetic pad is placed at the lower end of the clamp lever. It greatly improves the stability of the magnetic pad pressing and clamping the workpiece, prevents the workpiece from loosening and falling off due to unstable placement of the magnetic pad during processing, and improves processing accuracy and safety.

[0013] By setting a height adjustment hole, the height adjustment column is rotated after inserting an external pin into the height adjustment hole. Since the height adjustment column is threadedly connected to the assembly threaded hole, the rotating height adjustment column can be vertically raised and lowered along the inner wall of the height adjustment hole, thereby driving the top pile to rise and fall. As the rising top pile lifts the clamp lever, the clamp lever and clamp base rotate, causing the magnetic pad to move downward, thereby realizing the downward clamping and adjustment of the magnetic pad on the workpiece below, improving the convenience of downward clamping and adjustment of the workpiece.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1-5 As shown, the rotating magnetic pad structure of the clamp includes a clamp assembly 1, a lever adjustment assembly 2, and a magnetic pad assembly 3. The lever adjustment assembly 2 is disposed inside the clamp assembly 1. The magnetic pad assembly 3 is disposed at the front end of the clamp assembly 1. The clamp assembly 1 includes a clamp base 101. The clamp base 101 has an assembly threaded hole 102 disposed inside, and the assembly threaded hole 102 is integrally formed with the clamp base 101. The assembly threaded hole 102 has a height adjustment column 201 disposed inside. The height adjustment column 201 has a top post 202 fixedly disposed inside. The upper end of the top post 202 has a clamp lever 103 disposed, and the clamp lever 103 is rotatably connected to the clamp base 101. A magnetic pad 301 is disposed in front of the clamp lever 103. Connecting rods 302 are disposed at both ends of the rear of the magnetic pad 301. A slider 303 is disposed outside the connecting rods 302.

[0025] There are four connecting rods 302, and the connecting rods 302 are fixedly connected to the magnetic pads 301; there are two sliders 303; each slider 303 has a return spring 306 at its rear, and the return spring 306 is sleeved on the outside of the connecting rod 302; the rear end of the return spring 306 has a spring nut 305, and the spring nut 305 is fixedly connected to the return spring 306, and the spring nut 305 is threadedly connected to the connecting rod 302.

[0026] Each slider 303 has a screw pin 304 inside, and the screw pin 304 is bolted to the slider 303. The two screw pins 304 are respectively inserted into the front sides of the clamp lever 103 and rotated to connect.

[0027] The slider 303 is slidably connected along the axis of the connecting rod 302.

[0028] When the magnetic pad 301 rotates to the lower position of the clamp lever 103, the return spring 306 is in a compressed state; when the magnetic pad 301 rotates to the front position of the clamp lever 103, the return spring 306 is in a stretched state.

[0029] The height adjustment column 201 is threadedly connected to the assembly threaded hole 102.

[0030] The magnetic pad 301 is dynamically connected to the clamp lever 103 by rotating horizontally or downward 90 degrees along the front end of the clamp lever 103. The magnetic pad 301 is rotatably connected to both sides of the front end of the clamp lever 103 by the screw pin 304 inside the slider 303. With the slider 303 sliding along the connecting rod 302 and the elastic action of the return spring 306, the magnetic pad 301 can always be in close contact with the front and lower surfaces of the clamp lever 103 when rotating around the axis of the screw pin 304. This avoids the displacement and poor contact that usually occur when the magnetic pad 301 is placed at the lower end of the clamp lever 103. This greatly improves the stability of the magnetic pad 301 in pressing and clamping the workpiece, prevents the workpiece from loosening and falling off during processing due to unstable placement of the magnetic pad 301, and improves processing accuracy and safety.

[0031] Example 2

[0032] Based on Example 1, such as Figures 1-5 As shown, height adjustment holes 203 are provided around the height adjustment column 201, and the height adjustment holes 203 are integrally formed with the height adjustment column 201.

[0033] By using the height adjustment hole 203, the height adjustment column 201 is rotated after inserting an external pin into the height adjustment hole 203. Since the height adjustment column 201 is threadedly connected to the assembly threaded hole 102, the rotating height adjustment column 201 is vertically raised and lowered along the inner wall of the height adjustment hole 203, which in turn drives the top pile 202 to be raised and lowered. As the rising top pile 202 lifts the clamp lever 103, the clamp lever 103 and the clamp base 101 rotate, causing the magnetic pad 301 to move downward, thereby realizing the downward clamping adjustment of the magnetic pad 301 on the workpiece below, improving the convenience of downward clamping adjustment of the workpiece.
