It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] See also Figure 1-3 As shown, according to an embodiment of the present application, a special clamp for a swing arm limit block is provided, comprising: a hand-held portion 1, a clamping portion 2 and a connecting portion 3;

[0029] The clamping part 2 is arranged at both ends of the hand-held part 1, and the clamping part 2 away from the hand-held part 1 can clamp the rocker limiter, and the connecting part 3 is arranged between the clamping part 2 and the hand-held part 1 so that the hand-held part 1 and the clamping part 2 can be detachably connected.

[0030] Specifically, the clamping part 2 is installed on both sides of the handheld part 1. The clamping part 2 can clamp and fix the swing arm limit block. The staff can hold the handheld part 1 to press and fix the swing arm limit block to the position where the swing arm limit block needs to be welded and fixed. The device can replace the staff to manually fix the swing arm limit block, and the fixing stability is stronger. Moreover, the number of clamping parts 2 is two, which can fix two positions on the axis of the swing arm limit piece, thereby improving the fixing performance. A connecting part 3 is installed between the clamping part 2 and the handheld part 1. The connecting part 3 can realize a detachable connection between the handheld part 1 and the clamping part 2, which is convenient for replacing the clamping part 2 according to the size of the swing arm limit block, suitable for fixing swing arm limit blocks of different sizes, and also convenient for replacing the clamping part 2 after wear, which is convenient for subsequent welding use.

[0031] The clamping portion 2 includes a clamping plate 21 and a clamping rod 22;

[0032] The clamping plate 21 is provided with a clamping groove on one side away from the hand-held part 1 , the clamping rod 22 is threadedly connected to a side wall of the clamping plate 21 , the first end of the clamping rod 22 is located in the clamping groove, and the second end of the clamping rod 22 is located outside the clamping groove.

[0033] Specifically, the clamping part 2 includes a clamping plate 21 and a clamping rod 22. The clamping plates 21 are arranged at intervals along the axis of the hand-held part 1. A clamping groove is opened on the side of the clamping plate 21 away from the hand-held part 1 along the axial direction of the clamping plate 21. The clamping groove forms a clamping space for the rocker arm limit block. By rotating the second end of the clamping rod 22, the first end of the clamping rod 22 can be moved in the clamping groove, so that the rocker arm limit piece located in the clamping groove can be clamped and fixed. Compared with the hand-held fixation, its fixing stability is higher, which reduces the probability of the rocker arm limit piece slipping during welding. Rotating the clamping rod 22 can reduce the clamping space in the clamping groove, meet the clamping and fixation of rocker arm limit rods 33 of different sizes, and improve its scope of use.

[0034] Among them, the axis of the hand-held part 1 is perpendicular to the axis of the clamping groove, so that the clamping part 2 can be arranged in sequence along the axis of the rocker arm limiter. The rocker arm limiter is fixed by multiple clamping parts 2 to further enhance the fixation stability. Moreover, the hand-held part 1 is installed on the side of the clamping plate 21 away from the clamping groove. By pushing the hand-held part 1, the staff can make the rocker arm limiter fixed in the clamping groove contact with the position to be welded, thereby improving the welding efficiency.

[0035] Wherein, the clamping rod 22 is a screw rod.

[0036] The connecting part 3 includes: a connecting pipe 31, a limiting plate 32, a limiting rod 33, a baffle 34 and an elastic member 35;

[0037] The connecting tube 31 is arranged on the side of the clamping plate 21 away from the clamping groove, the limiting plate 32 is arranged on one side of the connecting tube 31, the first end of the limiting rod 33 passes through the limiting plate 32 and is arranged in the connecting tube 31, a baffle 34 is arranged on the limiting rod 33, and the elastic member 35 is arranged between the baffle 34 and the limiting plate 32.

[0038] The locking plate 33 is an L-shaped structure with one end connected to the side wall of the connecting tube 31 and the other end connected to the clamping plate 21. The first end of the locking rod 33 passes through the locking plate 32 and is located in the connecting tube 31. The baffle plate 34 is fixedly mounted on the locking rod 33 and is located in the space surrounded by the locking plate 32 and the connecting tube 31. The spring sleeve is arranged on the locking rod 33 and is also located in the space surrounded by the locking plate 32 and the connecting tube 31. When disassembling, pulling the locking rod 33 outward can drive the first end of the locking rod 33 to disengage from the connecting tube 31, so that the first end of the locking rod 33 disengages from the fixing hole 4 on the hand-held portion 1, which can be used to fix the hand-held portion 1 and the clamping plate 21. When the handle 1 is disassembled, the first end of the limit rod 33 can be disassembled between the parts 2; when installing, the limit rod 33 is pulled outward to drive the first end of the limit rod 33 to disengage from the connecting tube 31. At this time, the elastic member 35 is in a compressed state, and the end of the hand-held part 1 is placed in the connecting tube 31. The limit rod 33 is loosened, and driven by the elastic force of the elastic member 35, the first end of the limit rod 33 can enter the connecting tube 31 and then extend into the fixing hole 4 of the hand-held part 1, so as to facilitate the installation between the clamping part 2 and the hand-held part 1, and the clamping part 2 can be replaced according to the size of the swing arm limit piece to be fixed, so as to meet the use requirements of welding and fixing swing arm limit pieces of different sizes.

[0039] Among them, the connecting tube 31 is a rectangular tube structure, and the two ends of the hand-held part 1 are also rectangular structures, and the two ends of the hand-held part 1 are adapted to the inside of the connecting tube 31. When the end of the hand-held part 1 is installed inside the connecting tube 31, the position of the limit rod 33 matches the position of the fixing hole 4, which can realize the clamping and fixing of the hand-held part 1.

[0040] The elastic member 35 is a spring.

[0041] The second end of the limiting rod 33 is provided with a handle.

[0042] Specifically, the handle is installed on the second end of the limiting rod 33 to facilitate pulling the limiting rod 33.

[0043] The two ends of the hand-held part 1 are provided with fixing holes 4 . When the two ends of the hand-held part 1 are respectively arranged in the connecting tube 31 , the limiting rod 33 is arranged in the fixing holes 4 .

[0044] The handheld part 1 is a U-shaped structure.

[0045] Specifically, the hand-held portion 1 is a U-shaped structure, so that there is a certain distance between the hand-held portion 1 and the swing rod limiter clamped by the clamping portion 2, and there is space for hand-held holding.

[0046] A buffer sleeve 5 is disposed in the middle of the handheld part 1 .

[0047] Specifically, the buffer sleeve 5 is used to provide a buffer between the worker's hand and the hand-held part 1 to prevent the worker's hand from being injured due to direct holding of the hand-held part 1 for a long time.

[0048] A protective plate 6 is disposed on the handheld portion 1 and above the buffer sleeve 5 .

[0049] The protection plate 6 is made of metal material.

[0050] Specifically, the protection plate 6 can protect the hands of the workers and prevent the workers from being hurt by the splashing welding materials during welding.

[0051] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
