Description

Technical Field

[0001] The utility model relates to the technical field of joint connection, in particular to a front and rear asynchronous joint device of a bridge. Background Art

[0002] The leather cutting machine can cut the leather into corresponding shapes. The leather cutting machine has a conveying structure for conveying the leather and a cutting structure arranged on the bridge. The cutting structure is supported by the bridge, and the cutting structure is located on the beam of the bridge. The two slides of the bridge are respectively arranged on two parallel slide rails. The slides move on the slide rails to adjust the position of the cutting mechanism on the beam, and then the leather is cut through the cutting mechanism. When the bridge moves on the slide rails, due to the relatively long length of the bridge and the beam and the two slides are usually rigidly connected with screws, etc., if the two slides are subjected to different forces when moving on the slide rails, that is, the two slides are unevenly subjected to forces, the screws and screw holes at the connection between the beam and the slide may be deformed to a certain extent. Over a long period of time, the screws and screw holes may be severely damaged, affecting the connection between the beam and the slide, and easily affecting the subsequent normal disassembly and maintenance of the equipment.

[0003] The purpose of the present utility model is to provide a front and rear asynchronous joint device of a bridge to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The bridge front and rear asynchronous joint device comprises two joint members 1, a crossbeam is provided between the two joint members 1, and a sliding seat is provided on the sides of the two joint members 1 that are away from each other;

[0006] The joint component 1 includes a mounting seat 1, a mounting seat 2, and a center rod;

[0007] A mounting seat 1 is fixedly connected to the end of the beam, and a connecting hole 1 is opened on the side of the mounting seat 1;

[0008] The second mounting seat is fixedly connected to the side surface of the adjacent sliding seat, and the top surface and bottom surface of the second mounting seat are both provided with a second connecting hole;

[0013] Furthermore, the diameter of the second outer ring of the connecting ring is smaller than the diameter of the second inner ring of the connecting hole.

[0014] Preferably, the device further comprises a joint component 2 having the same structure as the joint component 1, and two pads are fixedly connected to the inner side surface of the second connection hole of the joint component 2.

[0015] Preferably, the device further comprises a joint component 3 having the same structure as the joint component 1, wherein the outer diameter of the connecting ring 2 of the joint component 3 is equal to the inner diameter of the adjacent connecting hole 2.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3 In the embodiment of the present invention, the front and rear asynchronous joint device of the bridge includes two joint parts 300, a crossbeam 100 is provided between the two joint parts 300, and a sliding seat 200 is provided on the side of the two joint parts 300 away from each other. The crossbeam 100 and the sliding seat 200 form a bridge, wherein the cutting mechanism of the cutting machine is provided on the crossbeam 100, and the sliding seat 200 is slidably provided on the slide rail of the cutting machine;

[0026] Joint component 1 300 includes mounting seat 1 310 , mounting seat 2 320 , and center rod 330 ;

[0027] Mounting seat 1 310 is fixedly connected to the end of beam 100, and a connecting hole 1 311 is provided on the side of mounting seat 1 310. Mounting seat 2 320 is fixedly connected to the side of adjacent sliding seat 200. There is a certain gap between the plates of mounting seat 1 310 and mounting seat 2 320, and the distance between the plates of mounting seat 1 310 and mounting seat 2 320 is one millimeter, so that mounting seat 1 310 can rotate relative to mounting seat 2 320. Connecting hole 2 321 is provided on the top and bottom surfaces of mounting seat 2 320, and center rod 330 is arranged inside connecting hole 1 311 and two connecting holes 2 321, and positioning screw 331 is screwed into the bottom end of center rod 330.

[0028] Specifically, the mounting seat 1 310 can be fixed to the beam 100 by screws, and the mounting seat 2 320 can be connected to the sliding seat 200 by screws, the top large end of the center rod 330 can be against the inner side of the beam 100, and the bottom large end of the positioning screw 331 can be against the bottom surface of the beam 100, so that the center rod 330 can be fixed to the beam 100 by the positioning screw 331, and the mounting seat 1 310 and the mounting seat 2 320 can be rotatably connected by the center rod 330, so that the beam 100 and the sliding seat 200 can be rotatably connected through the joint 1 300, and the sliding seat 200 can be rotated. When moving on the corresponding slide rails, if the two sliding seats 200 are subjected to uneven force during movement, causing the two sliding seats 200 to appear one in front and one behind, the beam 100 can be rotated relative to the sliding seat 200 through the joint part 1 300, thereby forming a certain buffer between the beam 100 and the sliding seat 200, which is beneficial to reducing the pulling force on the screws at the connection between the mounting seat 1 310 and the beam 100, and the screws at the connection between the mounting seat 2 320 and the sliding seat 200, which is beneficial to reducing the deformation and damage of the screws at the connection, avoiding affecting the connection between the beam rod and the slide seat, and avoiding affecting the subsequent normal disassembly, assembly and maintenance of the equipment.

[0029] Example 1

[0030] like Figure 2-3 As shown, in this embodiment, the side of the center rod 330 is rotatably connected to a connecting ring 1 340 that is rotatably connected to the inner side of the connecting hole 1 311, and the top and bottom of the side of the center rod 330 corresponding to the connecting holes 2 321 are both rotatably connected to connecting rings 2 350. The two connecting rings 2 350 are respectively located inside the two connecting holes 2 321, and the outer ring diameter of the connecting ring 2 350 is smaller than the inner ring diameter of the connecting hole 2 321.

[0031] During specific implementation, the mounting seat 1 310 and the center rod 330 can be rotatably connected through the connecting ring 1 340, and the inner ring diameter of the connecting hole 2 321 is larger than the outer ring diameter of the connecting ring 2 350. There is a certain gap between the inner wall of the connecting hole 2 321 and the annular side surface of the connecting ring 2 350. In this way, when the two sliding seats 200 are out of sync with each other, causing the two ends of the beam 100 to be out of sync with each other, the spacing between the two mounting seats 2 320 will change, and the center rod 330 will move a certain distance relative to the mounting seat 2 320, so that the beam 100 can rotate smoothly relative to the sliding seat 200, thereby smoothly performing buffering.

[0032] like Figure 3 As shown, in this embodiment, a displacement sensor 600 is provided on the inner side surface of the top of the second mounting seat 320 .

[0033] During specific implementation, the distance between the plates of mounting seat 1 310 and mounting seat 2 320 can be detected by the displacement sensor 600, so as to determine whether mounting seat 1 310 rotates relative to mounting seat 2 320, whether the two sliding seats 200 move synchronously, and whether the beam 100 is skewed. The force applied to the two sliding seats 200 can be corrected based on the detection results to avoid excessive gaps and greater damage to the bridge.

[0034] Example 2

[0035] Based on the first embodiment, Figure 4-5 As shown, in this embodiment, the device also includes a joint component 2 400 having the same structure as the joint component 1 300, and a joint component 3 500 having the same structure as the joint component 1 300. Two pads 700 are fixedly connected to the inner side surface of the connecting hole 2 321 of the joint component 2 400, and the outer ring diameter of the connecting ring 2 350 of the joint component 3 500 is equal to the inner ring diameter of the adjacent connecting hole 2 321.

[0036] During specific implementation, a joint part 3 500 can be set on one side of the beam 100, and a joint part 2 400 can be set on the other side of the beam 100. The two sliding seats 200 are respectively connected to the two ends of the beam 100 through the joint part 2 400 and the joint part 3 500. Since the outer wall of the connecting ring 2 350 of the joint part 3 500 contacts the inner wall of the connecting hole 2 321, the sliding seat 200 on one side can limit the position of one end of the joint part 3 500 through the joint part 3 500, so that one end of the beam 100 can only rotate relative to the sliding seat 200 on one side, and when the two sliding seats 200 move, The movement is not synchronized, the two sliding seats 200 are one in front and the other behind, and the distance between the two sliding seats 200 changes. When the beam 100 is skewed, the connecting ring 2 350 of the joint part 2 400 will move between the two pads 700, so that the beam 100 can rotate smoothly relative to the two sliding seats 200. Although this reduces the buffering range of the screws, when the two sliding seats 200 stop moving, the two sliding seats 200 can completely fix the position of the beam 100 through the joint part 2 400, the joint part 3 500 and the pad 700, which is beneficial to improve the stability of the beam 100.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
