Description

Technical Field

[0001] The utility model relates to the technical field of welding and fixing of a drive shaft sealing plate, in particular to a tool for assisting in welding and fixing a drive shaft sealing plate. Background Art

[0002] The drive shaft is a type of working device of the loader. It is a device that can promote the smoothness of the loader and enable the drive wheels to rotate at different angular speeds. The drive shaft seal plate is a component that passes through the drive shaft to assist in its fixed installation.

[0003] The utility model patent with domestic application number 202022898900.6 discloses a welding nut tooling, comprising a base and a vertical quick clamp fixed to the upper right end of the base, the upper left end of the base is evenly fixedly connected to at least two I-shaped blocks, a support column is provided in the middle position of the upper end of the I-shaped block, the support column is fixedly connected to the middle position of one end of the I-shaped block away from the positioning column, the movable frame of the vertical quick clamp is fixedly connected to the special-shaped plate, at least two rubber conical pressure heads are evenly installed on the lower end of the special-shaped plate, and at least two rubber conical pressure heads are respectively located directly above the at least two positioning columns. This design uses the positioning column to position and install the lathe and the nut, and then uses the vertical quick clamp to quickly press the corresponding nuts with the at least two rubber conical pressure heads, so as to realize one-time rapid positioning and pressing of the lathe and multiple nuts, thereby improving work efficiency.

[0004] Similarly, during the welding process of the factory drive shaft seal plate and the corresponding nut, due to the small size and light weight of the nut, it is easy to deviate during welding, and there are safety hazards in hand-held fixation. It is not convenient to use tools, welding is difficult, and welding efficiency is low. Therefore, a vertical quick clamp is also used to position and clamp the drive shaft seal plate. However, in the above-mentioned utility model patent, the rubber conical pressure head at the bottom of the vertical quick clamp is used to quickly press the corresponding nut. The nut is small in size and light in weight, and there is still a risk of deviation when subjected to lateral force. In addition, the thickness of the drive shaft seal plate workpiece itself is relatively small. During the welding process, the nut and the drive shaft seal plate welding position must not only ensure the heat dissipation effect at the top, but also ensure the heat dissipation effect at the bottom to prevent the drive shaft seal plate from being deformed due to heat accumulation caused by the thin drive shaft seal plate and poor heat dissipation effect at the bottom. The I-block itself is relatively thick and a base is still provided at its bottom, which affects the heat dissipation effect at the bottom of the drive shaft seal plate welding position during welding. Utility Model Content

[0005] In view of the deficiencies existing in the above-mentioned prior art, the purpose of the present invention is to provide a tooling to assist in the welding and fixing of the drive shaft sealing plate, so as to solve the risk of displacement when the nut is subjected to lateral force due to its small size and light weight during the welding process. In addition, the thickness of the drive shaft sealing plate workpiece itself is relatively small. During the welding process, the welding position of the nut and the drive shaft sealing plate must not only ensure the heat dissipation effect at the top, but also at the bottom to prevent the deformation of the drive shaft sealing plate welding position due to heat accumulation caused by the thin drive shaft sealing plate and poor heat dissipation effect at the bottom. The I-block itself is relatively thick and a base is still provided at its bottom, which affects the heat dissipation effect at the bottom of the drive shaft sealing plate welding position during welding.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tooling for assisting in the welding and fixing of a drive shaft sealing plate, comprising a pad, a drive shaft sealing plate welding part placed on the top of the pad, and four groups of nuts welded on the top of the drive shaft sealing plate welding part. The bottom of the pad is fixedly installed with a base frame by fixing bolts, and multiple groups of supporting frames are fixedly installed on the top of the base frame. Four groups of docking holes and limiting holes are respectively provided on the drive shaft sealing plate welding part, and four groups of positioning holes and four groups of auxiliary through holes are respectively provided on the pad. The positions of the positioning holes and the limiting holes correspond to each other, and the positions of the docking holes and the auxiliary through holes correspond to each other. A welding platform is welded on one side of the pad, and a vertical quick clamp is fixedly installed on the top of the welding platform.

[0007] After the backing plate and the base frame are fixed together, the drive shaft seal plate weldment is placed on top of the backing plate, and the nut to be welded is then placed on top of the drive shaft seal plate weldment. Finally, the nut and drive shaft seal plate weldment are positioned using vertical quick clamps to ensure their stability during the welding process.

[0008] Furthermore, a mounting plate is fixedly mounted on one end of the base frame, and two groups of mounting holes are provided on the mounting plate and the pad. One end between the base frame and the pad is fixedly mounted by a fixing bolt passing through the mounting hole.

[0009] The backing plate and one end of the base frame are fixedly mounted by passing a fixing bolt through the mounting hole, thereby increasing the mounting and dismounting function between the backing plate and the base frame, making it easier to use the tooling.

[0010] Furthermore, a clamping bearing block is fixedly mounted on one side of the bearing frame, and a docking groove for matching the clamping bearing block is provided on one side of the bottom of the pad.

[0011] The bottom of the pad is supported by multiple groups of supporting frames, so that the heat at the bottom of the driving shaft seal plate welding part and the nut welding position during the welding process is discharged through the gaps between the supporting frames, ensuring the heat dissipation effect during the welding process and avoiding heat accumulation that causes deformation between the welded parts and affects the use; and the clamping supporting block and the docking groove cooperate with each other, and the bottom of the pad is supported by the supporting frame, which ensures the heat dissipation effect of the tooling while ensuring the stability of its bottom during the welding process.

[0012] Furthermore, when the drive shaft sealing plate welding piece is placed on the top of the backing plate and the positioning hole and the limiting hole are aligned, one end of the drive shaft sealing plate welding piece is placed against the welding platform.

[0013] When the positioning hole and the limiting hole are aligned, one end of the drive shaft seal plate weldment is made to fit against the wall of the welding platform, and the positioning hole and the limiting hole are fixed and limited by the fixed workpiece, thereby increasing the stability of the drive shaft seal plate weldment during welding.

[0014] Furthermore, a rubber cushion layer is fixedly installed at the joint position between the welding platform and the driving shaft sealing plate welding piece.

[0015] By fixing the rubber pad on the wall of the welding platform, the wear of one end of the drive shaft seal plate weldment during the bonding process is reduced, thereby ensuring the integrity of the drive shaft seal plate weldment.

[0016] Furthermore, the vertical quick clamp includes a fixed frame fixedly installed on the top of the welding platform, an adjustment frame and a flip handle flipped on the fixed frame, an adjusting bolt is installed through the adjustment frame, and a connecting frame is fixedly installed at the bottom of the adjusting bolt, and four groups of positioning rods that cooperate with the nut member and the docking hole are threaded through the bottom of the connecting frame.

[0017] By moving the flip handle, the adjusting bolt is adjusted according to the position distance, so that after flipping, the four groups of positioning rods at the bottom respectively penetrate the four groups of nut parts and the docking holes opened on the drive shaft seal plate welding parts at the bottom of the nut parts, and penetrate the auxiliary through holes opened on the pad, thereby ensuring the stability of the nut parts and the drive shaft seal plate welding parts during the welding process.

[0018] Furthermore, four groups of clip fixing holes are provided on the welding platform, and the fixing frame and the welding platform are fixedly installed by fixing bolts passing through the clip fixing holes.

[0022] 2. The bottom of the pad is supported by multiple groups of supporting frames, so that the heat at the bottom of the driving shaft seal plate welding parts and the nut welding positions during the welding process can be discharged through the gaps between the supporting frames, thereby increasing the area of ​​the bottom heat dissipation channel, ensuring the heat dissipation effect during the welding process, and avoiding heat accumulation that causes deformation between the welded parts and affects the use; and the clamping bearing block and the docking groove cooperate with each other, and the bottom of the pad is supported by the supporting frame, while ensuring the heat dissipation effect of the tooling, ensuring the stability of its bottom during the welding process.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0031] Reference Figure 1-4 In the existing driving shaft sealing plate welding process, it is easy to produce welding difficulty and low welding efficiency. In addition, during the welding process, the heat at the welding position of the nut and the driving shaft sealing plate is high, resulting in deformation of the welded parts.

[0032] After repeated research and experiments, the applicant found that the cause of this problem was that the nut was small in size and light in weight, which could easily cause it to deviate during welding, and there were safety hazards when fixing it by hand, and it was not convenient to use tools; and in order to ensure the stability of welding, the welded parts were generally placed on a thicker base, which affected the heat dissipation effect during the welding process.

[0033] In response to this problem, the applicant has developed the technical solution of the present application; a tooling for assisting in the welding and fixing of a drive shaft seal plate, comprising a backing plate 1, a drive shaft seal plate welding piece 4 placed on top of the backing plate 1, and four sets of nuts 5 welded to the top of the drive shaft seal plate welding piece 4. The bottom of the backing plate 1 is fixedly mounted with a base frame 2 by fixing bolts, and one end of the base frame 2 is fixedly mounted with a mounting plate 21. Two sets of mounting holes 12 are provided on the mounting plate 21 and the backing plate 1. One end between the base frame 2 and the backing plate 1 is fixedly mounted by fixing bolts penetrating the mounting holes 12. The backing plate 1 and one end of the base frame 2 are fixedly mounted by fixing bolts penetrating the mounting holes 12, thereby increasing the functionality of mounting and disassembly between the backing plate 1 and the base frame 2, making it easier to use the tooling.

[0034] Multiple sets of support frames 22 are fixedly mounted on the top of the base frame 2. The support frames 22 are divided into three groups and evenly distributed on one side of the top of the base frame 2. The support frames 22 are relatively narrow, and the middle support frame 22 has a through hole at the top to facilitate heat dissipation from the top. The support frames 22 are arranged between different hole positions to avoid affecting the use of the hole positions. A snap-on support block 23 is fixedly mounted on one side of the support frame 22, and a docking groove 17 is provided on the bottom side of the pad 1 to mate with the snap-on support block 23. The multiple sets of support frames 22 support the bottom of the pad 1, allowing heat from the bottom of the drive shaft seal plate welding part 4 and the nut part 5 to be discharged through the gaps between the support frames 22 during the welding process. This increases the area of ​​the bottom heat dissipation channel, ensures heat dissipation during welding, and prevents heat accumulation that causes deformation between the welded parts and affects use. The snap-on support block 23 and the docking groove 17 cooperate with each other, and the support frames 22 support the bottom of the pad 1, ensuring the heat dissipation effect of the tooling while ensuring the stability of its bottom during the welding process.

[0035] The drive shaft sealing plate weldment 4 is provided with four groups of docking holes 41 and limiting holes 42, and the backing plate 1 is provided with four groups of positioning holes 13 and four groups of auxiliary through holes 14. The positioning holes 13 and the limiting holes 42 correspond to each other, and the docking holes 41 and the auxiliary through holes 14 correspond to each other. A welding platform 11 is welded and installed on one side of the backing plate 1. When the drive shaft sealing plate weldment 4 is placed on the top of the backing plate 1 and the positioning holes 13 and the limiting holes 42 are aligned, one end of the drive shaft sealing plate weldment 4 is placed against the welding platform 11. When the positioning holes 13 and the limiting holes 42 are aligned, one end of the drive shaft sealing plate weldment 4 is placed against the wall of the welding platform 11, and the positioning holes 13 and the limiting holes 42 are fixed and limited by a fixed workpiece, thereby increasing the stability of the drive shaft sealing plate weldment 4 during welding. A rubber pad 15 is fixedly installed at the fitting position of the welding platform 11 and the drive shaft sealing plate weldment 4. By fixing the rubber pad 15 on the wall of the welding platform 11 , the wear of one end of the driving shaft sealing plate welding part 4 during the bonding process is reduced, thereby ensuring the integrity of the driving shaft sealing plate welding part 4 .

[0036] A vertical quick clamp 3 is fixedly mounted on the top of the welding platform 11. The clamping bearing block 23 and the docking groove 17 are adapted to the size of the welding plane 11 to support the vertical quick clamp 3 mounted on the top thereof, thereby ensuring the stability of the top support provided by both sides of the base frame 2. This prevents the base plate 1 from being directly supported by the bearing frame 22, which could cause the base plate 1 to be unstable or tilted due to components of different weights placed or installed on top of the base plate 1. The vertical quick clamp 3 includes a fixed frame 31 fixedly mounted on the top of the welding platform 11, an adjustment frame 33 flip-mounted on the fixed frame 31, and a flip handle 32. An adjustment bolt 34 is installed through the adjustment frame 33, and a connecting frame 35 is fixedly mounted on the bottom of the adjustment bolt 34. Four sets of positioning rods 36 that cooperate with the nut member 5 and the docking hole 41 are threaded through the bottom of the connecting frame 35. By moving the flip handle 32 and adjusting the adjustment bolts 34 according to the position distance, the four sets of positioning rods 36 at the bottom of the flip handle 32 respectively penetrate the four sets of nuts 5 and the docking holes 41 defined in the drive shaft seal plate weldment 4 at the bottom of the nuts 5, and penetrate the auxiliary through-holes 14 defined in the backing plate 1, thereby ensuring the stability of the nuts 5 and the drive shaft seal plate weldment 4 during welding. Four sets of clamp fixing holes 16 are defined in the welding platform 11. Fixing bolts passing through the clamp fixing holes 16 secure the mounting bracket 31 to the welding platform 11. These fixing bolts passing through the clamp fixing holes 16 secure the vertical quick clamp 3 to the welding platform 11, ensuring its stability during use.

[0037] When the present invention is in use, first, two groups of fixing bolts are respectively passed through the two groups of mounting holes 12 opened on the pad 1 and the mounting plate 21 to fix the pad 1 and the base frame 2, so that the multiple groups of supporting frames 22 on the top of the base frame 2 support the bottom of the pad 1, and at the same time, the clamping supporting blocks 23 are clamped and fixed with the docking grooves 17 opened at the bottom of the pad 1, thereby ensuring the stability of the pad 1 during use; secondly, the drive shaft sealing plate welding part 4 is placed on the top of the pad 1, so that the four groups of limiting holes 42 opened on the drive shaft sealing plate welding part 4 are aligned with the positioning holes 13 opened on the pad 1, and the pad 1 with the positioning holes 13 opened according to the size of the drive shaft sealing plate welding part 4 is matched, so that one side of the drive shaft sealing plate welding part 4 is fitted with the side of the welding platform 11, and the fixed workpiece is passed through the limiting holes 42 and the positioning holes 13, thereby ensuring that the drive shaft sealing plate welding part 4 is stably limited on the pad 1. Then place the nut parts 5 that need to be welded on the corresponding auxiliary through holes 14 opened on the top of the drive shaft sealing plate welding part 4; finally, move the flip handle 32 and adjust the adjusting bolt 34 according to the position distance, so that after it is flipped, the four groups of positioning rods 36 at the bottom respectively pass through the four groups of nut parts 5 and the limiting holes 42 opened on the drive shaft sealing plate welding part 4 at the bottom of the nut parts 5. At this time, the welding worker can immediately start welding with accurate positioning. The nut parts 5 and the drive shaft sealing plate welding part 4 are fixed and not easy to deviate, thereby improving welding efficiency and accuracy; and there are gaps between the multiple groups of supporting frames 22 at the bottom of the pad 1, which is convenient for bottom heat dissipation at the welding position of the drive shaft sealing plate welding part 4, thereby reducing metal deformation caused by welding.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
