Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding tools, in particular to a welding gun clamping mechanism. Background Art
[0002] In welding operations, the clamping mechanism plays a key role in firmly fixing the welding gun. Traditionally, we place the welding gun between the fixing block and the clamping block, and then connect the two tightly with bolts to achieve a firm fixation of the welding gun. This clamping method has been widely used in the welding field because of its firm fixation.
[0003] However, in working environments where welding guns of different specifications need to be frequently replaced, this traditional clamping method shows its limitations; specifically, when the welding gun is placed between the fixed block and the clamping block, the operator often needs to adjust the bolt and hold the welding gun steady by hand at the same time until the two are tightly clamped. If the operator does not hold the welding gun, then during the bolt adjustment process, the welding gun is likely to be displaced or even fall off due to loss of support, which not only increases the difficulty of operation, but may also lead to reduced work efficiency. Utility Model Content
[0004] The utility model aims to provide a welding gun clamping mechanism for solving the problem that in the existing welding gun clamping mechanism, in an environment where the welding gun is frequently replaced, the bolts need to be adjusted and the welding gun needs to be stabilized by hand when the welding gun is clamped and fixed, otherwise the welding gun is easily displaced and falls off, which increases the difficulty of operation and reduces the work efficiency.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a welding gun clamping mechanism, including a mounting plate, and also including a first fixed plate connected to one end of the mounting plate, two fixed columns connected to one side of the first fixed plate and arranged at intervals, a fixed block connected to one end of the fixed column, a threaded rod connected to one side of the fixed block, a second fixed plate connected to one end of the two threaded rods, a slider sleeved on the threaded rod and movable horizontally along the length direction of the threaded rod, a fastening nut matched with the thread on the threaded rod and located between the second fixed plate and the slider, a spring sleeved on the threaded rod, a movable clamping mechanism connected between the two sliders, and a fixed clamping mechanism connected between the two fixed blocks, wherein the movable clamping mechanism and the fixed clamping mechanism are arranged relative to each other, and the two ends of the spring are respectively connected to the fixed block and the slider arranged relative to each other.
[0006] Furthermore, the fixed clamping mechanism and the movable clamping mechanism both include a U-shaped shell, three slots arranged on one side of the U-shaped shell and arranged at intervals, a clamping block arranged in the U-shaped shell and adapted to the interior of the U-shaped shell, three clamping blocks arranged on the outside of the clamping block and arranged at intervals, and screws respectively arranged on two clamping blocks, the three clamping blocks are respectively embedded in the interior of the three corresponding slots, one end of the screw is threadedly matched with the U-shaped shell, the U-shaped shell contained in the fixed clamping mechanism is connected to the two fixed blocks, and the U-shaped shell contained in the movable clamping mechanism is connected to the two sliders.
[0007] Furthermore, an opening is provided on one side of the second fixing plate, a pull rod is provided on one side of the U-shaped shell contained in the fixing clamping mechanism, one end of the pull rod passes through the opening and extends to one side of the second fixing plate, and a pull ring is provided on one end of the pull rod extending to the second fixing plate.
[0008] Furthermore, the outer wall of the pull ring is provided with anti-slip grooves.
[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] 1. When the welding gun is clamped and fixed, the movable clamping mechanism, two sliders, two threaded rods, two fastening nuts and the fixed clamping mechanism work together. Through the elastic force of the spring, the movable clamping mechanism and the fixed clamping mechanism jointly realize the initial clamping and positioning of the welding gun; the clamping mechanism is suitable for the working environment of frequent replacement of welding guns of different specifications, and can provide a stable initial clamping and positioning in advance before clamping and fixing the welding gun, which not only avoids the inconvenience caused by the operator having to hold the welding gun for a long time, but also reduces the risk of displacement or falling off of the welding gun due to lack of support during the current adjustment of the bolt. Therefore, this mechanism not only reduces the difficulty of operation, but also improves work efficiency.
[0011] 2. When the clamping blocks installed on the fixed clamping mechanism and the movable clamping mechanism need to be replaced due to wear, the clamping block and the U-shaped shell can be disassembled and reassembled with the help of the cooperation of the U-shaped shell, the clamping block, the slot, the clamping block and the screw; this process facilitates the rapid replacement of the worn clamping block and ensures the continuous operation of the clamping mechanism.

[0017] See also Figure 1-4 , a welding gun clamping mechanism, comprising a mounting plate 1, a first fixing plate 4 connected to one end of the mounting plate 1, two fixing columns 5 connected to one side of the first fixing plate 4 and arranged at intervals, a fixing block 6 connected to one end of the fixing column 5, a threaded rod 7 connected to one side of the fixing block 6, a second fixing plate 11 connected to one end of the two threaded rods 7, a slider 8 sleeved on the threaded rod 7 and movable horizontally along the length direction of the threaded rod 7, a fastening nut 9 threadedly matched with the threaded rod 7 and located between the second fixing plate 11 and the slider 8, a spring 10 sleeved on the threaded rod 7, a movable clamping mechanism 3 connected between the two sliders 8, and a fixed clamping mechanism 2 connected between the two fixing blocks 6, wherein the movable clamping mechanism 3 and the fixed clamping mechanism 2 are arranged relative to each other, and the two ends of the spring 10 are respectively connected to the relatively arranged fixing blocks 6 and the slider 8; a through hole for the threaded rod 7 to pass through the slider 8 is provided on the slider 8; when clamping and fixing the welding gun, first, the movable clamping mechanism 3 is pulled to one side, at which time, the two relative The connected slider 8 will slide along the threaded rod 7 and cause the spring 10 to stretch and deform. Subsequently, the welding gun is placed between the movable clamping mechanism 3 and the fixed clamping mechanism 2, and the movable clamping mechanism 3 is released. The two springs 10 shrink due to the elastic restoring force, thereby driving the slider 8 to move, and the slider 8 drives the movable clamping mechanism 3 to gradually approach the fixed clamping mechanism 2. In this process, the movable clamping mechanism 3 and the fixed clamping mechanism 2 are preliminarily clamped and positioned on the welding gun under the action of the spring 10. Subsequently, the two fastening nuts 9 are rotated one by one until the two fastening nuts 9 fit tightly with one side of the slider 8, thereby ensuring that the welding gun is firmly clamped and fixed. The clamping mechanism solves the problems encountered in a working environment where welding guns of different specifications are frequently replaced. Before clamping and fixing the welding gun, it can provide preliminary clamping and positioning, effectively avoiding the operator having to hold the welding gun for a long time or the risk of the welding gun being displaced or even falling off due to loss of support during the adjustment of the bolt, which not only reduces the difficulty of operation, but also improves work efficiency.
[0018] The fixed clamping mechanism 2 and the movable clamping mechanism 3 both include a U-shaped shell 15, three slots 16 arranged at intervals on one side of the U-shaped shell 15, a clamping block 17 arranged in the U-shaped shell 15 and adapted to the inside of the U-shaped shell 15, three clamping blocks 18 connected to the outside of the clamping block 17 and arranged at intervals, and screws 19 respectively arranged on two clamping blocks 18. The three clamping blocks 18 are respectively embedded in the insides of the three corresponding slots 16, and one end of the screw 19 is threadedly matched with the U-shaped shell 15. The U-shaped shell 15 contained in the fixed clamping mechanism 2 is connected to the two fixed blocks 6. , the U-shaped shell 15 contained in the movable clamping mechanism 3 is connected to the two sliders 8; when the clamping blocks 17 respectively connected to the fixed clamping mechanism 2 and the movable clamping mechanism 3 are worn and need to be replaced, first, the two screws 19 are rotated and removed, and then the clamping block 17 is pulled outward, and the clamping block 17 is taken out of the U-shaped shell 15. At the same time, the three clamping blocks 18 closely connected to the clamping block 17 are taken out from the corresponding three clamping grooves 16 and replaced with new clamping blocks 17; thereby facilitating the rapid replacement of the worn clamping blocks 17 and ensuring the continuous operation of the clamping mechanism.
[0019] An opening 12 is provided on one side of the second fixed plate 11, and a pull rod 13 is connected to one side of the U-shaped shell 15 contained in the movable clamping mechanism 3. One end of the pull rod 13 passes through the opening 12 and extends to one side of the second fixed plate 11, and a pull ring 14 is provided on the end of the pull rod 13 extending to the second fixed plate 11; when the movable clamping mechanism 3 is pulled to one side, the pull ring 14 is held by hand, and the pull rod 13 drives the movable clamping mechanism 3 to move to one side.
[0020] The outer wall of the pull ring 14 is provided with anti-skid patterns; when the pull ring 14 is held, the anti-skid patterns prevent the hand and the pull ring 14 from slipping.
[0021] Working principle: When clamping and fixing the welding gun, first, hold the pull ring 14, and the pull rod 13 drives the movable clamping mechanism 3 to move to one side. At this time, the two sliders 8 connected to it will slide along the threaded rod 7 and cause the spring 10 to stretch and deform. Then, place the welding gun between the movable clamping mechanism 3 and the fixed clamping mechanism 2, release the movable clamping mechanism 3, and the two springs 10 will shrink due to the elastic restoring force, thereby driving the slider 8 to move. The slider 8 drives the U-shaped shell 15 contained in the movable clamping mechanism 3 to gradually approach the U-shaped shell 15 contained in the fixed clamping mechanism 2. In this process, the movable clamping mechanism 3 and the fixed clamping mechanism 2 are connected. Under the action of the spring 10, the clamping blocks 17 contained in each mechanism 2 realize preliminary clamping and positioning of the welding gun. Then, the two fastening nuts 9 are rotated one by one until the two fastening nuts 9 are tightly fitted with one side of the slider 8, thereby ensuring that the welding gun is firmly clamped and fixed; the clamping mechanism solves the problems encountered in the working environment of frequent replacement of welding guns of different specifications. Before clamping and fixing the welding gun, it can provide preliminary clamping and positioning, effectively avoiding the operator having to hold the welding gun for a long time or the risk of the welding gun being displaced or even falling off due to loss of support during the adjustment of the bolt, which not only reduces the difficulty of operation, but also improves work efficiency.
