[0003] Currently, when welding hydraulic machinery is used in the production process, the parts of the hydraulic machinery are prone to movement during welding, resulting in significant deviations in the welding position. This necessitates repositioning the parts, which is inconvenient and reduces the welding efficiency of hydraulic machinery, thus hindering its production. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: when welding hydraulic machinery is performed using welding equipment during the production process, the parts of the hydraulic machinery are prone to movement during welding, resulting in significant deviations in the welding position. This necessitates repositioning the parts, which is inconvenient and leads to low welding efficiency for hydraulic machinery, thus hindering the production of hydraulic machinery. Therefore, this invention proposes a welding auxiliary device for the production of hydraulic machinery.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A welding auxiliary device for hydraulic machinery production includes a machine base and a support base.

A second clamping plate is provided at one end of the slide rod. A limit strip is fixedly connected to the horizontal plate. The slider has an opening, and a rotating assembly is provided inside the opening. The rotating assembly includes a rotating shaft rotatably mounted on the slider, and a support block is fixedly connected to the rotating shaft. The upper end face of the support block is fixedly connected to the lower surface of the horizontal plate. The slider is provided with a limiting component, which includes a plug rod that is slidably connected to the rotating shaft. A fixing sleeve with a circular cross-section is fixedly connected to one side surface of the slider. A plurality of protrusions arranged at equal intervals are fixedly connected to the inner wall of the fixing sleeve. A slot is opened at one end of the plug rod.

[0006] Preferably, a rotating disk is rotatably connected to the upper surface of the horizontal plate. The rotating disk has a T-shaped cross-section. A fixed shaft is fixedly connected to the upper surface of the rotating disk. A hinge rod is hinged to the fixed shaft. The end of the hinge rod away from the fixed shaft is hinged to the slide rod.

[0007] Preferably, a servo motor is fixedly mounted on the horizontal plate, and the drive end of the servo motor is fixedly connected to the rotating disk.

[0008] Preferably, a rubber pad is fixedly connected to one side surface of both the first clamping plate and the second clamping plate, and the limiting strip is disposed on the outside of the first clamping plate and the second clamping plate.

[0009] Preferably, the rotating shaft has a mounting groove, a rectangular rod is slidably connected in the mounting groove, a rotating rod is hinged to one end of the rectangular rod, and the end of the rotating rod away from the rectangular rod is hinged to the insertion rod.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0018] Reference Figures 1-5A welding auxiliary device for hydraulic machinery production includes a machine base 1 and a support base 2. The support base 2 is fixedly installed on the lower surface of the machine base 1. The support base 2 has a large mass and a relatively rough bottom surface, which can effectively prevent the support base 2 from sliding relative to the ground. A slider 4 is slidably connected to the machine base 1. A horizontal plate 9 is installed above the slider 4. A first clamping plate 6 is fixedly connected to the upper surface of the horizontal plate 9. A protective frame 8 is fixedly connected to the horizontal plate 9. A moving component is provided on the protective frame 8. The moving component is used for clamping parts. The moving component includes a slide rod 16 slidably installed on the protective frame 8. A second clamping plate 31 is provided at one end of the slide rod 16. A limit strip 5 is fixedly connected to the horizontal plate 9. An opening is opened on the slider 4. A rotating component is provided in the opening. The rotating component includes a rotating shaft 24 rotatably installed on the slider 4. A support block 7 is fixedly connected to the rotating shaft 24. The upper end face of the support block 7 is fixedly connected to the lower surface of the horizontal plate 9.

[0019] The slider 4 is provided with a limiting component, which includes a plug rod 19 that is slidably connected to the rotating shaft 24. A fixed sleeve 22 with a circular cross-section is fixedly connected to one side surface of the slider 4. A plurality of protrusions 23 arranged at equal intervals are fixedly connected to the inner wall of the fixed sleeve 22. A slot is opened at one end of the plug rod 19, and the protrusions 23 and the slot are engaged.

[0020] A rotating disk 27 is rotatably connected to the upper surface of the horizontal plate 9. The cross-section of the rotating disk 27 is T-shaped. A fixed shaft 28 is fixedly connected to the upper surface of the rotating disk 27. A hinge rod 29 is hinged to the fixed shaft 28. The end of the hinge rod 29 away from the fixed shaft 28 is hinged to the slide rod 16. A servo motor 26 is fixedly installed on the horizontal plate 9. The drive end of the servo motor 26 is fixedly connected to the rotating disk 27. The servo motor 26 drives the rotating disk 27 to rotate. As the fixed shaft 28 rotates together with the rotating disk 27, the tilt angle of the hinge rod 29 changes simultaneously. Under the transmission action of the hinge rod 29, the slide rod 16 slides relative to the protective frame 8, thereby driving the second clamping plate 31 to move closer to the first clamping plate 6.

[0021] Rubber pads 25 are fixedly connected to one side surface of the first clamping plate 6 and the second clamping plate 31. The limiting strip 5 is set on the outside of the first clamping plate 6 and the second clamping plate 31. The rubber pad 25, which is relatively soft, has a large friction when it comes into contact with the workpiece to be processed, so as to better clamp the workpiece to be processed, avoid slippage, and prevent the workpiece to be processed from being pinched. The limiting strip 5 has a certain positioning function for the placement of the workpiece to be processed, so as to facilitate the subsequent clamping of the workpiece by the first clamping plate 6 and the second clamping plate 31.

[0022] A mounting groove 21 is provided on the rotating shaft 24. A rectangular rod 18 is slidably connected in the mounting groove 21. A rotating rod 20 is hinged to one end of the rectangular rod 18. The end of the rotating rod 20 away from the rectangular rod 18 is hinged to the insertion rod 19. A spring 17 is sleeved on the rectangular rod 18. One end of the spring 17 is fixedly connected to the rectangular rod 18, and the other end of the spring 17 is fixedly connected to the rotating shaft 24. A handle 10 is fixedly connected to the end of the rectangular rod 18 away from the rotating shaft 24. When the handle 10 is pulled outward, the rectangular rod 18 slides relative to the rotating shaft 24 under the transmission action of the handle 10. The spring 17 is stretched and deformed, and the tilt angle of the rotating rod 20 changes simultaneously. Under the transmission action of the rotating rod 20, the insertion rod 19 slides relative to the rotating shaft 24, and the protrusion 23 disengages from the slot.

[0023] The machine base 1 has a rectangular groove 3 for the horizontal movement of the slider 4. A reciprocating screw 11 is rotatably connected in the rectangular groove 3. The slider 4 and the reciprocating screw 11 are threaded together. A mounting rod 15 is slidably connected to one end of the reciprocating screw 11 that passes through the machine base 1. The mounting rod 15 has a rectangular cross-section. A circular plate 12 is fixedly connected to the end of the mounting rod 15 away from the reciprocating screw 11. The circular plate 12 has multiple through holes 13 arranged at equal intervals. A limit shaft 14 is fixedly connected to one side surface of the machine base 1. In the initial state... One end of the limiting shaft 14 passes through the corresponding through hole 13. In use, the circular plate 12 is pulled outward first, and the mounting rod 15 slides relative to the reciprocating screw 11 at the same time. After the circular plate 12 moves, it will be located outside the limiting shaft 14. Then, the circular plate 12 is rotated. Under the transmission action of the mounting rod 15, the reciprocating screw 11 rotates relative to the machine base 1 at the same time, and the slider 4 moves along the reciprocating screw 11. This allows the position of the part to be processed to be adjusted, which facilitates the subsequent welding of the processed part.

[0024] The second clamping plate 31 is connected to the slide rod 16 by bolts 30. The slide rod 16 has a threaded groove for connecting the bolts 30. The lower end of the bolts 30 passes through the second clamping plate 31 and connects with the threaded groove on the slide rod 16, so that the slide rod 16 and the second clamping plate 31 can be firmly connected together. When the second clamping plate 31 is damaged due to long-term use, it is convenient to replace the second clamping plate 31 in a timely manner to facilitate the use of the device.

[0025] In this invention, during use, the part to be processed is first placed between the first clamping plate 6 and the second clamping plate 31, with one side surface of the part to be processed in contact with the surface of the limiting strip 5. Then, the servo motor 26 starts working, driving the rotating disk 27 to rotate. As the fixed shaft 28 rotates together with the rotating disk 27, the tilt angle of the hinge rod 29 changes simultaneously. Under the transmission action of the hinge rod 29, the slide rod 16 slides relative to the protective frame 8, thereby driving the second clamping plate 31 to move closer to the first clamping plate 6. During the movement of the second clamping plate 31... In the middle, it will push the part to be processed to move together until the two sides of the part to be processed are in close contact with the rubber pads 25 on the surfaces of the first clamping plate 6 and the second clamping plate 31 respectively. At this time, the servo motor 26 stops operating. Under the joint restraint of the first clamping plate 6 and the second clamping plate 31, the part to be processed can be prevented from moving randomly on the horizontal plate 9. The part to be processed will not move during the subsequent welding process, which can effectively avoid the deviation of the welding position. There is no need to reposition the part. The operation is more convenient and the welding efficiency of hydraulic machinery is higher, which is beneficial to the production of hydraulic machinery.

[0026] In the initial state, the slot at one end of the insertion rod 19 engages with the corresponding protrusion 23. During use, pulling the handle 10 outward causes the rectangular rod 18 to slide relative to the rotating shaft 24 under the transmission action of the handle 10. The spring 17 undergoes tensile deformation, and the tilt angle of the rotating rod 20 changes simultaneously. Under the transmission action of the rotating rod 20, the insertion rod 19 slides relative to the rotating shaft 24, and the protrusion 23 disengages from the slot. Then, rotating the handle 10 causes the rotating shaft 24 and the support block 7 to rotate simultaneously under the transmission action of the rectangular rod 18, thereby changing the tilt angle of the horizontal plate 9 and the part to be processed. After adjusting the angle of the part, the external force applied to the handle 10 is removed. Under the elastic force of the spring 17, the rectangular rod 18 retracts into the mounting groove 21, and one end of the insertion rod 19 engages with the corresponding protrusion 23. The tilt angle of the part to be processed can be adjusted according to the actual situation to facilitate subsequent welding of the part.
