The chain link is a basic unit, which is usually made of high-strength alloy steel through forging, stamping and heat treatment, and has an oval shape or other shapes according to the purpose and specification of the chain. Multiple chain links are connected in sequence to form a chain body.

[0003] In the chain link assembly process, the ordinary clamp cannot accurately and stably clamp the chain link, and the chain link is prone to deviation and shaking due to unilateral stress or uneven clamping force, which reduces the precision of the installation of the pin shaft, the sleeve and other components and lowers the assembly efficiency.

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0026] The metal chain clamp of this utility model embodiment will now be described with reference to the accompanying drawings.

[0027] like Figures 1-5 As shown, the metal chain clamp of this utility model embodiment may include...

[0028] Gripper cylinder 1.

[0029] The first clamping block 2 consists of two sets, with the two sets of first clamping blocks 2 fixed at two moving ends of the gripper cylinder 1, respectively.

[0030] The adapter 10 includes an adapter block 3, a slide bar 4, and an adapter roller 5. The adapter block 3 is in multiple sets, and multiple sets of adapter blocks 3 are fixed inside the first clamping block 2 in each set. The adapter blocks 3 at the middle and both ends are close to the cylinder body of the gripper cylinder 1.

[0031] The chain link has a smooth surface, and the adapter block 3 can gently and firmly clamp the chain link.

[0032] The slide bar 4 is slidably connected to the inner wall of the adapter block 3, and a spring 6 is provided between the adapter block 3 and the slide bar 4.

[0033] There are multiple sets of adapter rollers 5. Each set of slide rods 4 is rotatably connected to a set of adapter rollers 5. The adapter rollers 5 can adjust the rotation direction in real time and always maintain good contact with the surface of the chain link.

[0034] When dealing with elliptical chain links, the layout and angle of the adapter block 3 on the inner side of the first clamping block 2 can closely fit the elliptical contour of the chain link, applying force from multiple key positions to ensure that the chain link does not shift or wobble during clamping. For example, in the processing of general mechanical transmission chains, the first clamping block 2 can adapt to the clamping requirements of various standard specifications of chain links, eliminating the need for frequent changes of clamping components and improving production efficiency.

[0035] Specifically, the clamping cylinder 1 assembly line enables the clamps to be adapted to the assembly of various chains.

[0036] In one embodiment of the present invention, an L-shaped support plate 7 is also included. There are two sets of L-shaped support plates 7. The two sets of L-shaped support plates 7 are respectively fixed at both ends of the cylinder body of the gripper cylinder 1. The L-shaped support plates 7 can be used to assemble the gripper cylinder 1 on the equipment.

[0037] In one embodiment of the present invention, a second clamping block 8 is further included. The second clamping block 8 is fixed to the first clamping block 2 by two sets of straight rods 11, and an adapter 10 is provided on the inner wall of the second clamping block 8.

[0038] The first clamping block 2 can fix the sheet metal of the processing chain link, and the addition of the second clamping block 8 makes the whole more adaptable and connected.

[0039] In one embodiment of the present invention, a mounting base 9 is fixed on the bottom surface of the cylinder body of the gripper cylinder 1. The surface of the mounting base 9 is provided with mounting holes, and the mounting base 9 is also used for mounting the clamp on the equipment.

[0040] Specifically, in actual operation, the bottom mounting base 9 of the gripper cylinder 1 is fixed to the corresponding equipment through the mounting holes on its surface. Simultaneously, two sets of L-shaped support plates 7 are used to assist in assembling the gripper cylinder 1 onto the equipment, ensuring a stable installation. Next, the gripper cylinder 1 is activated, and its two moving ends drive the two sets of first clamping blocks 2. When dealing with chain links of different shapes, if the chain link is elliptical, the adapter blocks 3, arranged with a specific layout and angle on the inner side of the first clamping blocks 2, closely fit the elliptical contour of the chain link, applying force from multiple key positions to prevent chain link displacement or wobbling. If the chain link surface is smooth, the adapter blocks 3 can grip it gently and firmly. During clamping, the sliding rod 4, slidably connected to the inner wall of the adapter block 3, adapts to minor dimensional deviations or irregular shapes of the chain link under the action of the spring 6 between it and the adapter block 3. The adapter roller 5, rotatably connected to the end of the sliding rod 4, adjusts its rotation direction in real time, always maintaining good contact with the chain link surface. For situations requiring more stable clamping, a second clamping block 8, fixed to the first clamping block 2 by two sets of straight rods 11, comes into play. The adapter 10 on its inner wall works in conjunction with the adapter 10 on the inner side of the first clamping block 2 to further enhance the clamping effect. Simultaneously, the first clamping block 2 can also fix the sheet metal block used for processing chain links, making the overall fixture more adaptable to chain link connections. The entire fixture is assembled on the production line via a gripper cylinder 1, efficiently adapting to the assembly of various chains.

[0041] In summary, the metal chain clamp of this utility model embodiment effectively improves the stability and reliability of chain link clamping in chain processing, transportation and other scenarios, adapts to chain link deviations and precisely adjusts the chain link gaps, further reduces friction, and ensures smooth chain operation under various working conditions.
