[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please refer to the attached Figures 1 to 7 As shown, a chain clamp for a chain cleaning machine in an embodiment of the utility model includes a chain 1 and a sprocket assembly 3. The chain 1 is meshed and connected between the two sprocket assemblies 3. An opening and closing assembly 4 is provided on the inner side of the chain 1. The chain 1 includes a plurality of chain plates 11 in pairs. The plurality of pairs of chain plates 11 are staggered end to end and fixedly connected with axle pins 12 at the connection. When in use, the chain 1 is driven to move by the rotation of the sprocket assembly 3.

[0029] A plurality of clamping jaw assemblies 2 are evenly spaced and connected to the inner side of the chain 1, and the clamping jaw assembly 2 includes a first clamping rod 21 and a second clamping rod 22. The upper ends of the first clamping rod 21 and the second clamping rod 22 are fixedly connected with a chuck 23. The inner lower end of the first clamping rod 21 is rotatably connected to the second clamping rod 22. The lower ends of the first clamping rod 21 and the second clamping rod 22 are rotatably sleeved with a shaft sleeve 24. The inner sides of the two shaft sleeves 24 are respectively fixedly sleeved on the outer ends of the two axle pins 12. The lower end of the first clamping rod 21 is fixedly connected with an inclined rod 25. The clamping jaw assembly 2 is used to clamp the workpiece and can move with the chain 1, thereby driving the workpiece in and out of the cleaning tank. Specifically, when the first clamping rod 21 and the second clamping rod 22 are closed, the workpiece is stably clamped by the two chucks 23. When opened, the first clamping rod 21 is driven to open by pushing the inclined rod 25 upward, so that the two chucks 23 are separated and release the workpiece.

[0030] The opening and closing assembly 4 includes two fixed frames 41, a support plate 42 is fixedly connected between the two fixed frames 41, a cylinder 43 is fixedly connected to the middle of the upper end surface of the support plate 42, and a push head 44 is fixedly connected to the protruding end of the cylinder 43. The opening and closing assembly 4 is used to open the jaw assembly 2. Specifically, when the jaw assembly 2 moves to the top of the opening and closing assembly 4, the cylinder 43 drives the push head 44 to rise, contact with the lower end of the inclined rod 25 and push the inclined rod 25, thereby opening the first clamping rod 21, so that the jaw assembly 2 releases the material to facilitate loading and unloading.

[0031] The upper ends of the two fixing frames 41 are fixedly connected with a cover seat 45, the inner side of the cover seat 45 is close to the chain 1, and the inner sides of the two cover seats 45 are provided with a through groove 46, and the axle pin 12 can pass through the through groove 46. The set cover seat 45 can limit the chain 1 to prevent the chain 1 from running off, and the set through groove 46 is convenient for the axle pin 12 to pass through and will not interfere with the movement of the chain 1.

[0032] The first clamping rod 21 and the second clamping rod 22 are fixedly connected with an insertion rod 28 at the middle of the outer ends, and a tension spring 29 is hung between the two insertion rods 28. The tension spring 29 is provided to facilitate the reset of the first clamping rod 21 after opening, and also to improve the clamping stability.

[0033] The sprocket assembly 3 includes two wheel bodies 31. The outer ends of the two wheel bodies 31 are evenly spaced with multiple arc grooves 32 corresponding to the axle pins 12. The two ends of the axle pins 12 are meshed with the arc grooves 32. The chain 1 is meshed with the arc grooves 32 on the wheel bodies 31 through the protruding axle pins 12 on both sides, so that the meshing position is located on both sides of the chain 1. When the sprocket assembly 3 rotates, it will not interfere with the middle clamping jaw assembly 2.

[0034] A backing plate 27 is provided between the outer side of the shaft sleeve 24 and the chain plate 11 . The backing plate 27 is sleeved between the two shaft pins 12 . The backing plate 27 is provided to protect the shaft sleeve 24 .

[0035] The end of the inclined rod 25 extends to the bottom of the second clamping rod 22 and is rotatably connected to a roller 26. The roller 26 can rotate to reduce friction when the jacking head 44 contacts the inclined rod 25, thereby reducing wear.

[0036] Working principle: When in use, the chain 1 is driven to move by the rotation of the sprocket assembly 3. Since the jaw assembly 2 is connected to the outer end of the shaft pin 12, it can move with the chain 1. When the jaw assembly 2 moves to the top of the opening and closing assembly 4, the cylinder 43 drives the push head 44 to rise, contact with the lower end of the inclined rod 25 and push the inclined rod 25, thereby opening the first clamping rod 21, so that the two clamps 23 are separated, which is convenient for loading and unloading. After the cylinder 43 retracts, the first clamping rod 21 is reset due to the tension of the tension spring 29, and the two clamps 23 are closed to clamp the material. Compared with the hanging method, the clamping stability is stronger, and the workpiece is not easy to fall during cleaning. In addition, multiple jaw assemblies 2 are opened by the same opening and closing assembly 4, so that there is no need to set an independent opening and closing mechanism on each jaw assembly 2, which has low cost and strong practicality.

[0037] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
