Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to a track link positioning and clamping device. Background Technology

[0002] Track links are the connecting parts in the tracks of construction machinery. They are an important component of the tracks, and their main function is to connect the various parts of the tracks, ensuring the integrity and stability of the tracks. Track link positioning and clamping devices are used to ensure that track links are stably clamped in the correct position during the manufacturing, repair, or processing of track links for tracked construction machinery. Such devices are crucial for improving production efficiency, ensuring processing accuracy, and ensuring operational safety.

[0003] A search revealed that Chinese Patent Publication No. CN215469733U discloses a track link tooling fixture. By providing a chip removal mechanism in the area where the track link contacts the base, when the track link is lifted from the fixture, the weight of the groove plate on the outside of the rotating shaft is greater than the weight on the inside, causing the groove plate to rotate outward. This allows the generated debris to be discharged downward into the groove of the worktable, thereby initially cleaning the large debris on the top of the groove plate and preventing the accumulation of debris from affecting the clamping and positioning of the track link.

[0004] In the above technical solution, the chip removal mechanism on the base avoids the risk of reduced clamping effect due to large debris when positioning the track link. When the track link needs to be positioned and clamped, it needs to be processed. The processing of the track link often requires double-sided or multi-sided processing, and it is not possible to flip the track link after a single clamping operation. This will lead to the need for repeated clamping of the track link, resulting in reduced processing accuracy due to clamping errors. Therefore, a track link positioning and clamping device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a track link positioning and clamping device, which aims to improve the problem that the existing track link positioning and clamping device cannot switch the processing surface of the track link after a single clamping, resulting in repeated clamping and reduced processing accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a track link positioning and clamping device, comprising a base, a positioning structure provided on the top of the base, the positioning structure including a fixing plate, a support shaft rotatably connected to the inner wall of the fixing plate, a motor fixedly connected to the end of the support shaft, a positioning block fixedly connected to the end of the support shaft away from the motor, an electric push rod fixedly connected to the outer wall of the positioning block, a push plate fixedly connected to the output end of the electric push rod, an electromagnet fixedly connected to the side wall of the push plate, an adjustment component provided on the surface of the base, and a fixing component provided on the surface of the fixing plate.

[0007] As a further description of the above technical solution:

[0008] The inner surface of the positioning block is provided with an embedding groove, and a rubber pad is fixedly connected to the inner surface of the positioning block. A hook and loop male face is fixedly connected to the side wall of the push plate, and a hook and loop female face is provided on the side wall of the hook and loop male face. A sponge ring is fixedly connected to the side wall of the hook and loop female face.

[0009] As a further description of the above technical solution:

[0010] The lower surface of the fixing plate is fixedly connected to the upper surface of the base, and the outer wall of the motor is fixedly connected to the side wall of the fixing plate.

[0011] As a further description of the above technical solution:

[0012] The adjustment assembly includes a movable groove, a threaded rod rotatably connected to the inner wall of the movable groove, a knob fixedly connected to the outer wall of the threaded rod, and a movable block threadedly connected to the outer wall of the threaded rod.

[0013] As a further description of the above technical solution:

[0014] The fixing assembly includes a connecting shaft, and a positioning plate is fixedly connected to the side wall of the fixing plate by a support rod. Bolts are threadedly connected to the inner wall of the positioning plate.

[0015] As a further description of the above technical solution:

[0016] The movable slot is formed on the upper surface of the base, and the outer wall of the movable block is adapted to the inner wall of the movable slot.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the bolt is threaded to the inner wall of the connecting shaft.

[0019] As a further description of the above technical solution:

[0020] The sponge ring is fitted onto the outer wall of the electromagnet.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the two sides of the track link are fixed by setting an electric push rod, a push plate and a positioning block. The electromagnet increases the clamping force when the track link is laid flat to accept positioning. The adjustment component allows the two sets of positioning blocks to be adjusted according to the length of the track link. The motor and the fixing component can make the track link after positioning and clamping flip to accept processing, reducing the error in processing accuracy caused by repeated positioning and clamping, saving positioning and clamping time and improving production efficiency.

[0023] 2. In this utility model, the embedded groove allows the chain link to be embedded inside when vertically positioned, increasing stability. The sponge ring and rubber pad increase the friction between the positioning block and the chain link while avoiding damage caused by the impact of the positioning clamping force. The male and female sides of the Velcro allow for quick replacement of the deformed sponge ring after long-term use, ensuring that the chain link has a buffering function when positioned and clamped.

The top of the base 1 is provided with a positioning structure, which includes a fixing plate 2. There are two sets of fixing plates 2, and the two sets of fixing plates 2 are symmetrically arranged about the central axis of the base 1. The inner wall of the fixing plate 2 is rotatably connected to a support shaft 3. The end of the support shaft 3 is fixedly connected to a motor 4. The motor 4 is installed on a set of fixing plates 2 on the right side of the base 1. The end of the support shaft 3 away from the motor 4 is fixedly connected to a positioning block 8. There are two sets of positioning blocks 8, and the two sets of positioning blocks 8 are mirror images of each other about the central axis of the base 1. The outer wall of the positioning block 8 is fixedly connected to an electric push rod 9. The output end of the electric push rod 9 is fixedly connected to a push plate 10. The side wall of the push plate 10 is fixedly connected to an electromagnet 11. The surface of the base 1 is provided with an adjustment component, and the surface of the fixing plate 2 is provided with a fixing component.

[0033] Reference Figures 3-5 The lower surface of the fixing plate 2 is fixedly connected to the upper surface of the base 1. The lower surface of the fixing plate 2 on the left side is not fixedly connected to the base 1, but is in contact with the upper surface of the base 1. The outer wall of the motor 4 is fixedly connected to the side wall of the fixing plate 2. The adjustment assembly includes a moving groove 12, which is opened on the upper surface of the base 1. The inner wall of the moving groove 12 is rotatably connected to a threaded rod 15. The outer wall of the threaded rod 15 is fixedly connected to a knob 14. The outer wall of the threaded rod 15 is threadedly connected to a moving block 13. The outer wall of the moving block 13 is adapted to the inner wall of the moving groove 12. The top of the moving block 13 is fixedly connected to the bottom of the fixing plate 2 on the left side. The fixing assembly includes a connecting shaft 7. The side wall of the fixing plate 2 is fixedly connected to a positioning plate 5 through a support rod. The inner wall of the positioning plate 5 is threadedly connected to a bolt 6. The outer wall of the bolt 6 is threadedly connected to the inner wall of the connecting shaft 7. The outer wall of the connecting shaft 7 is rotatably connected to the inner wall of the fixing plate 2 on the left side. The outer wall of the end of the connecting shaft 7 away from the positioning plate 5 is fixedly connected to the outer wall of the second set of positioning blocks 8.

[0034] Reference Figure 2 and Figure 5The inner surface of the positioning block 8 is provided with an embedding groove 16, which provides a place for the chain link to enter the positioning block 8 vertically, increasing the contact area between the positioning block 8 and the chain link. A rubber pad 17 is fixedly connected to the inner surface of the positioning block 8, which increases the friction between the chain link and the positioning block 8. A hook and loop fastener male surface 18 is fixedly connected to the side wall of the push plate 10, and a hook and loop fastener female surface 19 is provided on the side wall of the hook and loop fastener male surface 18. The hook and loop fastener male surface 18 and the hook and loop fastener female surface 19 are bonded to each other, which facilitates the replacement of the sponge ring 20. A sponge ring 20 is fixedly connected to the side wall of the hook and loop fastener female surface 19, and the sponge ring 20 is sleeved on the outer wall of the electromagnet 11.

[0035] Working principle: Place the base 1 on the operating table of the processing equipment. The operator rotates the knob 14 clockwise or counterclockwise according to the length of the track link. The knob 14 controls the rotation direction of the threaded rod 15, causing the moving block 13 to drive the left fixed plate 2 to adjust the distance between the left and right fixed plates 2. According to the processing requirements of the track link, the positioning orientation of the track link is switched so that the screw holes face upwards or towards the operator. The two ends of the track link are placed inside the left and right sets of positioning blocks 8. Since the screw holes are located on the side of the track link, usually at the edge, if the screw holes face the operator and the track link is inserted vertically, it will be embedded in the corresponding insertion groove 16. At the same time, the two sets of electric push rods 9 are activated so that the push plate 10 gradually approaches the track link until the sponge ring 20 and the rubber pad 17 are in contact with the two sides of the track link, providing positioning and clamping. If the track link is flat with the screw holes facing upwards, after the two sides of the track link are placed inside the positioning block 8, the track link cannot enter the insertion groove 16. At this time, the two ends of the track link are placed inside the positioning block 8. When the two sets of electromagnets 11 are energized, they generate magnetic force, which combines the clamping force with the magnetic attraction force, reducing the risk of poor positioning and clamping effect due to the reduction of positioning surfaces. The main material of the track link is 35MnBM steel. 35MnBM steel has good mechanical properties and stability, which can meet the application requirements of track links in engineering machinery and military machinery. Since 35MnBM steel is a common steel, its main component is iron, so it has magnetic conductivity and can be stably fixed by the electromagnets 11. Finally, the track link with positioning and clamping can be processed. Before processing, manually reverse the bolts 6 to remove the fixing of the positioning plate 5 to the connecting shaft 7. During processing, turn on the motor 4. The motor 4 slowly drives the support shaft 3 to rotate 180 degrees. Since the two ends of the track link are positioned, the positioning block 8 on the left side can be driven by the pulling force of the track link rotation to drive the connecting shaft 7 to rotate at the same time, thereby allowing the track link after positioning and clamping to flip over, so that it can be processed on multiple sides after a single positioning and clamping.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
