Description

Technical Field

[0001] This utility model belongs to the technical field of welding auxiliary equipment, specifically a laser welding clamping fixture for welding bent plate chains. Background Technology

[0002] Welded bent plate chains are primarily designed for wood processing involving strong impacts, material abrasion, and high dust levels. They can withstand high-load impacts and exhibit durable wear resistance, thus extending their service life. They are mainly used in grain scraper conveyors, soybean meal scraper conveyors, industrial bulk material conveyors, and wood processing, and are suitable for wood processing equipment, grain and oil processing equipment, and the paper industry. Welded bent plate chains are welded using a new type of specialized automatic welding machine, completing double-sided welds in a single clamping operation. Various accessories on the chain links are welded robotically, ensuring consistent welding quality and dimensional accuracy. When welding bent plate chains, clamping fixtures are required for the welding process.

[0003] A welding clamping fixture for a curved chain, disclosed in Chinese patent document CN213615077U, involves placing one curved chain plate to be welded on a left curved chain plate limiting plate with the other end resting on a left curved chain plate support plate. A sleeve is placed on a sleeve support block. Then, another curved chain plate is placed on a right curved chain plate limiting plate. The right curved chain plate limiting plate is then pushed to bring the curved chain plate and sleeve into contact. A pin is used to fix the right curved chain plate limiting plate. The other end of the curved chain plate is then placed on the right curved chain plate support plate. Welding is then performed at the contact point between the sleeve and the curved chain plate. After welding the upper semicircle of the welded part, the half-welded curved chain is flipped over to weld the other half, thus achieving the welding and repair of the curved chain. This provides a stable welding environment for the welding and repair of the curved chain, ensuring the stability of the welding process.

[0004] However, in the process of implementing the above technical solution, the following technical problems were found:

[0005] When the existing welding clamping fixture for curved chain supports the welding work between the left and right curved chain plates and the sleeve, because the curved chain plates are mounted on the support plate, they need to be flipped over after the welding work of the upper part is completed to continue the work. During the mounting and bending process, the left and right curved chain plates are prone to displacement, which can easily reduce the welding quality. Utility Model Content

[0006] To overcome existing shortcomings, this application provides a laser welding clamping fixture for welded bent chain plates. By having a second limiting rod pass through the interior of the first bent chain plate, the second bent chain plate, and the sleeve, and insert it into the interior of the positioning sleeve, and the first limiting rod passes through the interior of the first bent chain plate, the second bent chain plate, and the fixed seat plate, and after the locking nut is threadedly connected to the threaded rod and makes contact with the surface of the fixed seat plate, one end of the positioning sleeve and the limiting pin respectively makes contact with the surfaces of the second and first bent chain plates. The surfaces of one end of the movable and fixed seat plates also make contact with the surfaces of the second and first bent chain plates. This clamps and fixes the bent chain blocks between the fixed and movable clamping parts, providing good stability. This solves the problem that existing welding clamping fixtures for welded bent chain plates, when supporting the welding work between the left and right bent chain plates and the sleeve, are prone to displacement during the erection and bending process because the bent chain plates are mounted on the support plate, which easily reduces welding quality.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A laser welding clamping fixture for welding bent plate chains includes a movable clamping component and a fixed clamping component. The movable clamping component includes a movable seat plate. A first limiting rod is fixedly connected to the surface of one end of the movable seat plate. A threaded rod is fixedly connected to one end of the first limiting rod. A limiting column is fixedly connected to the surface of the other end of the movable seat plate. A second limiting rod is fixedly connected to one side of the limiting column.

[0009] The fixing clamp includes a fixing plate, and a positioning sleeve is fixedly connected to the surface of one end of the fixing plate.

[0010] A curved plate chain block is provided between the fixed clamping member and the movable clamping member. The curved plate chain block includes a first curved plate chain plate and a second curved plate chain plate. The first curved plate chain plate and the second curved plate chain plate are arranged symmetrically on the left and right sides. A sleeve is provided between one end of the first curved plate chain plate and the second curved plate chain plate.

[0011] In one possible implementation, a linkage shaft is fixedly connected to one end of the fixed base plate, the linkage shaft is located on the opposite side of the positioning sleeve, and one end of the linkage shaft is connected to a motor via a coupling.

[0012] In one possible implementation, the second limiting rod is movably connected inside the first bending plate chain, the second bending plate chain, and the sleeve, and one end of the second limiting rod is plugged into the inside of the positioning sleeve.

[0013] In one possible implementation, one end of the positioning sleeve is in surface contact with the second curved plate chain, and one end of the limiting post is in surface contact with the first curved plate chain.

[0014] In one possible implementation, the surface of one end of the fixed seat plate is in contact with the surface of the second curved plate chain plate, and the surface of one end of the movable seat plate is in contact with the surface of the first curved plate chain plate.

[0015] In one possible implementation, the first limiting rod is movably connected inside the first bent plate chain, the second bent plate chain, and the fixed seat plate, and the threaded rod is externally threaded with a locking nut, one side of which is in contact with the surface of the fixed seat plate.

[0016] In one possible implementation, the bottom of the motor is assembled with a tooling top plate, and the four corners of the bottom of the tooling top plate are fixedly connected with first columns. The bottoms of the four first columns are fixedly connected to the same tooling base plate. The tooling top plate has a movable groove machined inside, and the fixed clamping component, movable clamping component, and bent plate chain block are rotatably connected inside the movable groove.

[0017] In one possible implementation, the bottom of the sleeve is movably connected to a support base, the bottom end of the support base is fixedly connected to a second column, and the bottom end of the second column is fixedly connected to the top of the tooling base plate.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0020] 2. In this solution, by using a motor to control the linkage shaft to drive the fixed seat plate to rotate, the bent plate chain block can be driven to rotate under the support of the support seat, which facilitates the welding head of the welding equipment with a small range of motion to perform welding work between the sleeve and the first bent plate chain plate and the second bent plate chain plate.

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] Example 1:

[0027] This embodiment describes the specific structure of the laser welding clamping fixture for welded bent plate chains. See details for further information. Figures 1-3 As shown, it includes a movable clamping member 7 and a fixed clamping member 6. The movable clamping member 7 includes a movable seat plate 71. A first limiting rod 72 is fixedly connected to the surface of one end of the movable seat plate 71. A threaded rod 73 is fixedly connected to one end of the first limiting rod 72. A limiting column head 74 is fixedly connected to the surface of the other end of the movable seat plate 71. A second limiting rod 75 is fixedly connected to one side of the limiting column head 74.

[0028] The fixing clamp 6 includes a fixing base plate 61, and a positioning sleeve 63 is fixedly connected to one end of the fixing base plate 61.

[0029] Among them, a bent plate chain block 9 is provided between the fixed clamping member 6 and the movable clamping member 7. The bent plate chain block 9 includes a first bent plate chain plate 91 and a second bent plate chain plate 92. The first bent plate chain plate 91 and the second bent plate chain plate 92 are arranged symmetrically on the left and right. A sleeve 93 is provided between one end of the first bent plate chain plate 91 and the second bent plate chain plate 92.

[0030] Meanwhile, in order to facilitate clamping and fixing the bent plate chain block 9 between the fixed clamping member 6 and the movable clamping member 7, the second limiting rod 75 is movably connected to the inside of the first bent plate chain plate 91, the second bent plate chain plate 92 and the sleeve 93. After one end of the second limiting rod 75 is inserted into the inside of the positioning sleeve 63, one end of the second limiting rod 75 can be positioned, so that the first limiting rod 72 is movably connected to the inside of the first bent plate chain plate 91, the second bent plate chain plate 92 and the fixed seat plate 61. The locking nut 11 is threadedly connected to the outside of the threaded rod 73.

[0031] Secondly, in order to enable the fixed clamping member 6 and the movable clamping member 7 to drive the bent plate chain block 9 to rotate, the threaded connection state of the threaded rod 73 and the locking nut 11 is adjusted. After one side of the locking nut 11 is in contact with the surface of the fixed seat plate 61, one end of the positioning sleeve 63 can be in contact with the surface of the second bent plate chain plate 92, one end of the limiting column head 74 can be in contact with the surface of the first bent plate chain plate 91, and one end of the fixed seat plate 61 can be in contact with the surface of the second bent plate chain plate 92, and one end of the movable seat plate 71 can be in contact with the surface of the first bent plate chain plate 91.

[0032] By adopting the above technical solution:

[0033] The above design involves the second limiting rod 75 passing through the interiors of the first curved plate chain 91, the second curved plate chain 92, and the sleeve 93, and being inserted into the interior of the positioning sleeve 63. The first limiting rod 72 passes through the interiors of the first curved plate chain 91, the second curved plate chain 92, and the fixed seat 61. After the locking nut 11 is threadedly connected to the threaded rod 73 and makes surface contact with the fixed seat 61, one end of the positioning sleeve 63 and the limiting pin 74 respectively makes surface contact with the second curved plate chain 92 and the first curved plate chain 91. Then, the surfaces of one end of the movable seat plate 71 and the fixed seat plate 61 are in contact with the surfaces of the second curved plate chain plate 92 and the first curved plate chain plate 91, which can clamp and fix the curved plate chain block 9 between the fixed clamping member 6 and the movable clamping member 7. When welding the sleeve 93 to the first curved plate chain plate 91 and the second curved plate chain plate 92, the fixed seat plate 61 can be controlled to rotate, so that the curved plate chain block 9 rotates as a whole to perform welding work on the sleeve 93 to the first curved plate chain plate 91 and the second curved plate chain plate 92 around the perimeter, without any displacement.

[0034] Example 2:

[0035] Based on Example 1, this example introduces the specific structure of the laser welding clamping fixture for welding bent plate chains. A linkage shaft 62 is fixedly connected to one end of the fixed seat plate 61. The linkage shaft 62 is located on the opposite side of the positioning sleeve 63. One end of the linkage shaft 62 is connected to a motor 4 through a coupling.

[0036] Among them, the bottom of the motor 4 is assembled with a tooling top plate 5, and the four corners of the bottom of the tooling top plate 5 are fixedly connected with the first column 2. The bottom of the four first columns 2 is fixedly connected with the same tooling base plate 1. The tooling top plate 5 has a movable groove 8 machined inside. When the motor 4 controls the linkage shaft 62 to rotate, it drives the bent plate chain block 9 between the fixed seat plate 61 and the movable seat plate 71 to rotate, so that the fixed clamping part 6, the movable clamping part 7 and the bent plate chain block 9 are rotatably connected inside the movable groove 8, which facilitates the welding work between the sleeve 93 and the first bent plate chain plate 91 and the second bent plate chain plate 92 without the welding head of the welding equipment moving too much.

[0037] Secondly, in order to set up the bending plate chain block 9 so that the motor 4 can drive the bending plate chain block 9 to rotate stably using the fixed clamping part 6 and the movable clamping part 7, a support seat 10 is set at the bottom of the sleeve 93 so that the sleeve 93 can move inside the support seat 10. The bottom end of the support seat 10 is fixedly connected to the second column 3, and the bottom end of the second column 3 is fixedly connected to the top of the tooling base plate 1, thereby setting the support seat 10 to a certain height.

[0038] The specific operating steps are as follows:

[0039] S1. The second limiting rod 75 passes through the inside of the first bent plate chain plate 91, the second bent plate chain plate 92 and the sleeve 93 and is inserted into the inside of the positioning sleeve 63. The first limiting rod 72 passes through the inside of the first bent plate chain plate 91, the second bent plate chain plate 92 and the fixed seat plate 61. The locking nut 11 is threadedly connected to the threaded rod 73. The bent plate chain block 9 is clamped between the fixed seat plate 61 and the movable seat plate 71.

[0040] S2, the connection point between the welding sleeve 93 and the first bent plate chain plate 91 and the second bent plate chain plate 92, the motor 4 controls the linkage shaft rod 62 to drive the fixed seat plate 61 to rotate, when the bent plate chain block 9 rotates inside the movable groove 8, the sleeve 93 rotates under the support of the support seat 10.

[0041] By adopting the above technical solution:

[0042] The above design utilizes the motor 4 to control the linkage shaft 62 to drive the fixed seat plate 61 to rotate, which in turn drives the bent plate chain block 9 to rotate under the support of the support seat 10. This facilitates the welding head of the welding equipment with a small range of motion to perform welding work between the sleeve 93 and the first bent plate chain plate 91 and the second bent plate chain plate 92.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
