Description

Technical Field

[0001] This invention relates to the field of welding technology, and in particular to a positioning fixture for welding the side plates of hydraulic supports. Background Technology

[0002] As a key protective component of hydraulic supports, the stability of the side guard plate directly affects the structural stability and service life of the hydraulic support. When damage occurs, it needs to be repaired by welding. Existing repair methods require disassembly before welding, which increases the intensity of disassembly and reassembly. While direct welding without disassembly is also an option, this method suffers from insufficient positioning accuracy. Furthermore, the pre-treatment and post-weld slag removal processes are separate, requiring separate grinding and slag removal tools, making the process cumbersome. Therefore, we propose a positioning fixture for welding hydraulic support side guard plates to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the background art and to propose a positioning tool for welding the side plate of a hydraulic support.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A positioning fixture for welding the side plate of a hydraulic support includes a side plate on the hydraulic support, a positioning support is placed on the hydraulic support, and a fixing component is installed between the hydraulic support and the positioning support. The fixing component is used to fix the positioning support after it is placed on the hydraulic support. A lifting frame is installed on the positioning support via an adjustment component, and the horizontal and vertical positions of the corresponding positioning support of the lifting frame are controlled by the adjustment component. The lifting frame is fixedly mounted on a mounting base via an electric telescopic rod. A servo motor is mounted on the mounting base via a moving component. A drive shaft is fixedly mounted on the drive end of the servo motor. A connecting frame is fixedly mounted on one end of the drive shaft. A welding gun is fixedly mounted on one side of the connecting frame. The connecting frame consists of two circular blocks of different sizes and a connecting rod. The connecting rod is fixed between the two circular blocks. The upper circular block is fixed on the drive shaft, and the lower circular block is rotatably mounted with an electric telescopic rod. A transmission component is installed between the electric telescopic rod and the drive shaft. An elastic cleaning component is installed on the electric telescopic rod. A grinding block is fixedly installed at one end of the electric telescopic rod, and the grinding block is located inside the telescopic cover.

[0005] In the above-mentioned positioning fixture for welding the side plate of a hydraulic support, the fixing component includes a vertical limiting plate, a strip limiting plate, a limiting support assembly, and a locking assembly. A vertical limiting plate is integrally formed and fixedly installed on both sides of the positioning support. A strip limiting plate is slidably installed on each of the two vertical limiting plates through the limiting support assembly. A locking assembly is installed between the strip limiting plate and the hydraulic support and the corresponding vertical limiting plate. The locking assembly includes a round hole, a locking rod, and a locking screw block. The vertical limiting plate, the strip limiting plate, and the hydraulic support are all provided with corresponding round holes. A locking rod is engaged between the corresponding round holes, and a locking screw block is threaded onto one end of the locking rod.

[0006] In the aforementioned positioning fixture for welding the side plate of a hydraulic support, the limiting support assembly includes a stepped slide groove and a stepped slider. A stepped slide groove is provided on the side of the two vertical limiting plates that are close to each other, and multiple stepped sliders are fixedly installed on the side of the two strip limiting plates that are far from each other, and the stepped sliders are slidably installed on the corresponding stepped slide grooves.

[0007] In the aforementioned positioning fixture for welding the side plate of a hydraulic support, the adjusting component includes an electric slide rail one, a sliding block one, an electric slide rail two, a sliding block two, and a vertical adjusting component. Two electric slide rails one are symmetrically fixedly installed on the positioning support, and a sliding block one is installed on each of the two electric slide rails one. An electric slide rail two is fixedly installed on both of the two sliding blocks one. A sliding block two is installed on the electric slide rail two, and a vertical adjusting component is installed on the sliding block two.

[0008] In the aforementioned positioning fixture for welding the protective plate of a hydraulic support, the vertical adjustment component includes a disc, a hydraulic cylinder, and a hydraulic rod. The disc is fixedly mounted on the sliding block, the hydraulic cylinder is fixedly mounted on the disc, and the hydraulic rod is mounted on the hydraulic cylinder, with the upper end of the hydraulic rod fixedly connected to the lifting frame.

[0009] In the aforementioned positioning fixture for welding the side plate of a hydraulic support, the moving component includes a mounting groove, an electric slide rail three, a sliding block three, and a disc two. The mounting base has a mounting groove on the side near the side plate. The electric slide rail three is fixedly installed on the mounting groove. The sliding block three is installed on the electric slide rail three. The disc two is fixedly installed on the outer side of the sliding block three, and a servo motor is fixedly installed on the disc two.

[0010] In the aforementioned positioning fixture for welding the side plate of a hydraulic support, the transmission component includes a one-way bearing and a transmission belt. The electric telescopic rod 2 rotates through the lower circular block. One end of the electric telescopic rod 2 is equipped with a one-way bearing, and a transmission belt is sleeved between the one-way bearing and the drive shaft.

[0011] In the aforementioned positioning fixture for welding the protective plate of a hydraulic support, the elastic protective component includes a telescopic cover. The telescopic cover is fixedly installed on the outermost thread of the electric telescopic rod two. The telescopic cover consists of an annular cover, an annular seat, a magnetic block one, and a magnetic block two. The annular seat is fixedly installed on the outermost thread of the electric telescopic rod two. The side of the annular seat away from the circular block is open. An annular groove is formed on the outer wall of the opening. The annular cover is slidably installed on the annular groove. The annular cover is hollow with both ends connected. Multiple mounting grooves are formed on the inner wall of the annular groove near the circular block. A magnetic block one is fixedly installed in the mounting groove. A magnetic block two that cooperates with magnetic block one is fixedly installed at one end of the annular cover located in the annular groove, and the diameter of magnetic block two is smaller than the wall thickness of the annular cover.

[0012] In the aforementioned positioning fixture for welding the side plate of a hydraulic support, the annular groove is provided with multiple strip-shaped sliding grooves along the circumference, and multiple limiting sliders that cooperate with the annular sliding grooves are fixedly installed on the outside of the annular cover.

[0013] In the aforementioned positioning fixture for welding the side plate of a hydraulic support, the inner wall of the annular cover is arc-shaped, and the arc on the side near the electric telescopic rod is greater than the arc on the side near the side plate.

[0014] Compared with existing technologies, the advantages of this invention are: 1. By fixing the components, the positioning support and hydraulic support form a stable and unified benchmark, eliminating relative offset during the welding process; the adjustment components realize the precise linkage between the horizontal and vertical of the lifting frame, and together with the electric slide rail group, a three-dimensional adjustment system is constructed to drive the welding gun to complete the precise positioning at any position; then, through the coordination of the servo motor and the connecting frame, the welding angle can be flexibly adjusted to realize the one-time completion of the welding process of the side plate in all positions.

[0015] 2: The fixed components, through the bidirectional limiting of vertical and strip limiting plates, combined with stepped slides and locking components, achieve stable fixation of the positioning support on the hydraulic support, effectively avoiding the relative displacement of the guard plate and tooling during welding, ensuring the accuracy of weld position and the consistency of penetration depth, and improving the stability of welding quality from the source.

[0016] 3: The positioning and moving components work together, and with the help of the combination of electric slide rails, hydraulic cylinders, and electric telescopic rods, the welding gun can be flexibly adjusted in multiple dimensions in the horizontal, vertical and near-side plate directions. With the angle adjustment function driven by servo motor, it can accurately adapt to the welding requirements of different positions and curved surfaces of the side plate.

[0017] 4: The welding gun and grinding block are integrated into the same connecting frame. Through the cooperation of the transmission component and the elastic cleaning component, the pre-treatment grinding before welding, welding operation and post-weld debris collection are integrated into one process. No additional tools are required, which simplifies the operation steps and avoids debris contamination of the welding area.

[0018] 5: The elastic cleaning and protection components achieve elastic fit of the telescopic cover through magnetic adsorption and limiting slider guidance, which not only ensures the chip collection effect during grinding, but also adapts to the slight undulations of the side plate surface. Combined with the one-way bearing, it ensures the independent and stable operation of the welding and grinding processes, further enhancing the practicality and reliability of the device.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-11 A positioning fixture for welding the side plate of a hydraulic support includes a side plate 2 on a hydraulic support 1. A positioning support 3 is placed on the hydraulic support 1. A rubber pad can be fixedly installed on the lower surface of the positioning support 3. The elasticity of the rubber pad prevents the positioning support 3 from directly contacting the hydraulic support 1 during placement, and also improves the stability after subsequent fixing. A fixing component is installed between the hydraulic support 1 and the positioning support 3. The fixing component is used to fix the positioning support 3 after it is placed on the hydraulic support 1, and the fixing component is easy to operate.

[0023] The fixing components include vertical limiting plates 4, strip limiting plates 5, limiting support components, and locking components. A vertical limiting plate 4 is integrally formed and fixedly installed on both sides of the positioning support 3. A strip limiting plate 5 is slidably installed on each of the two vertical limiting plates 4 via the limiting support components. The limiting support components include stepped grooves 6 and stepped sliders 7. A stepped groove 6 is provided on the side of the two vertical limiting plates 4 that is close to each other. Multiple stepped sliders 7 are fixedly installed on the side of the two strip limiting plates 5 that is far from each other, and the stepped sliders 7 are slidably installed on the corresponding stepped grooves 6. A locking component is installed between the strip limiting plate 5, the hydraulic support 1, and the corresponding vertical limiting plate 4; the locking component includes a round hole and a locking rod 8. The locking screw block 9, vertical limiting plate 4, strip limiting plate 5, and hydraulic support 1 are all provided with corresponding round holes. A locking rod 8 is installed between the corresponding round holes, and a locking screw block 9 is threaded onto one end of the locking rod 8. Only one set is set on one side as shown in the figure. Multiple sets can be set in other settings. In this case, this part can be set as a strip plate, and multiple rods are fixed on the strip plate. After one end of the rod passes through the round hole, it is locked and fixed by multiple locking screw blocks 9. Similarly, rubber pads can be fixed on the side where the two vertical limiting plates 4 are close to each other and on the side where the two strip limiting plates 5 are far apart, so as to avoid direct contact and improve the firmness of the fixation.

[0024] Reference Figures 1-11 A lifting frame 16 is installed on the positioning support 3 via an adjusting component. The adjusting component controls the horizontal and vertical position adjustment of the lifting frame 16 corresponding to the positioning support 3. The adjusting component includes an electric slide rail 10, a sliding block 11, an electric slide rail 2 12, a sliding block 2 13, and a vertical adjusting component. Two electric slide rails 10 are symmetrically fixedly installed on the positioning support 3. Each of the two electric slide rails 10 is equipped with a sliding block 11. The two sliding blocks 11 are jointly fixedly installed with an electric slide rail 2 12. A second sliding block 13 is installed, and a vertical adjustment component is installed on the second sliding block 13. The vertical adjustment component includes a disc, a hydraulic cylinder 14, and a hydraulic rod 15. The disc is fixedly installed on the second sliding block 13, the hydraulic cylinder 14 is fixedly installed on the disc, and the hydraulic rod 15 is installed on the hydraulic cylinder 14. The upper end of the hydraulic rod 15 is fixedly set to the lifting frame 16. The cooperation between the electric slide rail 10 and the first sliding block 11, as well as the cooperation between the electric slide rail 2 12 and the second sliding block 13, are existing technologies and will not be described in detail here.

[0025] The lifting frame shown in Figure 16 consists of a circular disc and a rod frame, which are fixedly connected. The lower surface of the circular disc is fixedly connected to the upper end of the hydraulic rod 15. One end of the rod frame is fixedly mounted with a mounting base 18 via an electric telescopic rod 17. A servo motor 21 is mounted on the mounting base 18 via a moving component. A drive shaft is fixedly mounted on the drive end of the servo motor 21. A connecting frame 22 is fixedly mounted on one end of the drive shaft. A welding gun 23 is fixedly mounted on one side of the connecting frame 22. The welding gun 23 is part of the prior art, and its use process... There are other cooperating parts, which are existing technologies and are not shown in the figure; the electric telescopic rod 17 is set to facilitate the appropriate movement of the mounting base 18 according to the position of the side plate 2; the moving components include the mounting groove 19, the electric slide rail 20, the sliding block 3, and the disc 2. The mounting base 18 has a mounting groove 19 on the side near the side plate 2. The electric slide rail 20 is fixedly installed on the mounting groove 19. The sliding block 3 is installed on the electric slide rail 20. The disc 2 is fixedly installed on the outside of the sliding block 3, and the servo motor 21 is fixedly installed on the disc 2.

[0026] Reference Figures 1-11 The connecting frame 22 consists of two circular blocks of different sizes and a connecting rod fixed between them. The connecting rod is fixed between the two circular blocks. The upper circular block is fixed to the drive shaft, and the lower circular block is rotatably mounted with an electric telescopic rod 24. A transmission component is installed between the electric telescopic rod 24 and the drive shaft. The transmission component includes a one-way bearing 25 and a transmission belt 26. The electric telescopic rod 24 rotates through the lower circular block. One end of the electric telescopic rod 24 is equipped with a one-way bearing 25, and the transmission belt 26 is sleeved between the one-way bearing 25 and the drive shaft. The one-way bearing 25 allows the electric telescopic rod 24 to be controlled to rotate as needed, without affecting its rotation. A one-way bearing is installed between the welding gun 23 and the drive shaft to ensure the stability of the welding gun 23 during use. At the same time, when the electric telescopic rod 24 rotates, although the welding gun 23 will also rotate, the welding gun 23 is not working and does not contact the guard plate 2, so it does not affect the use. Of course, a one-way bearing can also be installed between the welding gun 23 and the drive shaft. In that case, a stabilizing structure needs to be added to prevent the welding gun 23 from rotating when there is no set rotation. It is also important to note the positional relationship between the electric telescopic rod 24 and the welding gun 23. The distance between the two should be sufficient for the rotation of the welding gun 23.

[0027] An elastic cleaning component is installed on the electric telescopic rod 24. The elastic cleaning component includes a telescopic cover 27. A grinding block is fixedly installed at one end of the electric telescopic rod 24, and the grinding block is located inside the telescopic cover 27. The telescopic cover 27 is fixedly installed on the outermost thread of the electric telescopic rod 24. The telescopic cover 27 consists of an annular cover, an annular seat, a magnetic block one, and a magnetic block two. The annular seat is fixedly installed on the outermost thread of the electric telescopic rod 24. The side of the annular seat away from the round block is open. An annular groove is formed on the outer side wall of the opening. An annular cover is slidably installed on the annular groove. The annular cover is hollow and connected at both ends. Multiple installation grooves are formed on the inner wall of the annular groove near the round block. A magnetic block one is fixedly installed in the installation groove. The annular cover is located inside the groove. A magnetic block two (which repels magnetic block one) is fixedly installed at one end of the annular groove, and the diameter of magnetic block two is smaller than the wall thickness of the annular cover. Furthermore, multiple strip-shaped grooves are opened circumferentially in the annular groove, and multiple limiting sliders that cooperate with the annular grooves are fixedly installed on the outside of the annular cover, so that the annular cover can only slide along the direction of the strip-shaped grooves relative to the annular grooves and will not rotate on them. At the same time, the inner wall of the annular cover is arc-shaped, and the arc on the side near the electric telescopic rod 24 is greater than the arc on the side near the guard plate 2. The purpose of this setting is to allow the debris generated during grinding to be collected more directly and better. Afterwards, the threaded telescopic cover 27 can be removed to clean the collected debris.

[0028] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0029] The working principle of this invention is as follows; Installation of positioning support 3: Place positioning support 3 on hydraulic support 1 so that the round hole on vertical limiting plate 4 corresponds to the round hole on hydraulic support 1. Then slide strip limiting plate 5 onto vertical limiting plate 4. Finally, use locking rod 8 and locking screw block 9 to fix positioning support 3 on hydraulic support 1 (at this time, vertical limiting plate 4 and strip limiting plate 5 are engaged in the middle of the part of hydraulic support 1, which is a plate). Adjustment of the position of welding gun 23: The welding gun 23 can be adjusted along the length direction of the hydraulic support 1 by the cooperation of electric slide rail 10 and sliding block 11; the welding gun 23 can be adjusted along the width direction of the hydraulic support 1 by the cooperation of electric slide rail 22 and sliding block 23; the welding gun 23 can be adjusted along the height direction of the hydraulic support 1 by the cooperation of hydraulic cylinder 14 and hydraulic rod 15; at the same time, the welding gun 23 can be moved relative to the side guard plate 2 along the direction of mounting base 18 (the mounting base 18 and the side guard plate 2 are flush at this time). Pre-welding preparation: The telescopic cover 27 is moved by the operation of the electric telescopic rod 24 and puts into contact with the guard plate 2. At this time, the grinding block is not in contact with the guard plate 2, and the movement of the telescopic cover 27 can clean the area to be ground. When grinding is required, the grinding block is brought into contact with the guard plate 2 by the electric telescopic rod 24. At this time, the telescopic cover 27 is in a compressed state, but still in contact with the guard plate 2. The servo motor 21 is turned on, and the servo motor 21 drives the electric telescopic rod 24 to rotate through the transmission belt 26 and the one-way bearing 25 (at this time, the one-way bearing 25 is in a self-locking state). The rotation of the electric telescopic rod 24 can drive the grinding block to rotate, thereby performing grinding. At the same time, in conjunction with the operation of some structures in the position adjustment of the welding gun 23 mentioned above, the required welding area can be effectively ground. Welding: Welding gun 23 can be used to perform welding directly. In addition, the movement required during the welding process can be achieved by using the structure mentioned in the above position adjustment section. At the same time, the angle of rotation of welding gun 23 (relative to the drive shaft) can be controlled independently when needed, so as to facilitate better welding.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
