Description

Technical Field

[0001] This utility model relates to the field of piston rod air gouging, specifically to an auxiliary device for piston rod air gouging. Background Technology

[0002] Piston rod air planing auxiliary device is a tool used to improve the efficiency and accuracy of air planing operations. It ensures the stability of the air planing process by stabilizing the piston rod position, reducing vibration and heat dissipation. It is suitable for repairing or machining piston rod surfaces. This device can improve machining quality, extend tool life and reduce operation difficulty, and is widely used in the fields of mechanical repair and manufacturing.

[0003] Chinese patent CN218311396U discloses a handheld air planer angle-fixing auxiliary device, including a primary adjuster. The primary adjuster includes a guide rod, both ends of which are connected to a trolley. A sleeve is fitted in the middle of the guide rod. By combining the primary adjuster with the secondary adjuster, the air planer gun can have a larger adjustment range, thus enabling air planing operations on metal plates even when they are far from the edge, thereby increasing the air planing range of the device. Furthermore, the extension rod slides on the extension tube, which facilitates the second-level lateral position adjustment of the air planer gun. The combination of the two further improves the lateral position adjustment range of the air planer gun.

[0004] The aforementioned patented air gouging angle-fixing auxiliary device does not restrict the lateral movement trajectory of the trolley when assisting the air gouging, which easily leads to positional deviation during lateral movement of the trolley. Furthermore, during the process of clamping and fixing the pipe, there is no clamping or lifting structure for the pipe, making it inconvenient to place or remove the pipe. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary device for piston rod air gouging. The transmission frame can drive the first clamping plate to clamp and fix the piston rod by moving horizontally in the longitudinal direction. Conversely, the transmission frame can move vertically upward to lift the repaired piston rod. Furthermore, the sliding block slides inside the sliding rail, and the movement trajectory can be restricted by the rotation of the second roller. The stable movement trajectory can improve the effect of piston rod air gouging repair and solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for piston rod air planing, comprising a base with a support frame on one side of the outside, a sliding rail on one side of the inside of the base, a sliding block slidably connected to the sliding rail at the lower end of the outside of the support frame, a pair of second rollers horizontally arranged at both the upper and lower ends of the sliding block, a first roller at the lower end of the sliding block, a bracket at the upper end of the base, first clamping plates on both sides of the upper end of the bracket, a movable groove inside the bracket, and a support plate arranged along the movable groove inside the base.

[0007] Preferably, the other side of the two first clamping plates is welded and fixed by a transmission frame, and a first threaded rod is provided through the inside of the transmission frame, and the outside of the first threaded rod is threadedly engaged with the through position of the transmission frame.

[0008] Preferably, the movable groove passes through the bracket and extends into the interior of the base, and the bracket is welded and fixed to the transmission frame.

[0009] Preferably, the center of the second roller is rotatably connected to the inside of the sliding block.

[0010] Preferably, a sliding rod is slidably provided at the upper end of the outer side of the support frame.

[0011] Preferably, a fourth threaded rod is provided at one end of the sliding rod, and the fourth threaded rod is welded and fixed to the sliding rod. A connecting plate is provided on one side of the fourth threaded rod, and the center of the connecting plate is rotatably connected to the outside of the fourth threaded rod.

[0012] Preferably, a transmission block is provided on one side of the fourth threaded rod, and the interior of the transmission block is engaged with the external thread of the fourth threaded rod.

[0013] Preferably, a pointer is welded to one side of the outer wall of the connecting plate, and an angle reference table is arranged around the outer wall of the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] When repairing and fixing a cylindrical piston rod in a gap, this invention places the cylindrical piston rod on the upper end of the bracket. Clockwise rotation of the first threaded rod causes the two first clamping plates to press and fix the cylindrical piston rod on both sides of the upper end of the bracket. Conversely, counterclockwise rotation of the first threaded rod allows the clamping plates to lift the cylindrical piston rod longitudinally from the movable groove position, facilitating user removal. Furthermore, when the connecting disc for holding the carbon rod and the second clamping plate move laterally on the first roller to repair the piston rod, the sliding block will slide inside the sliding rail, sliding simultaneously with the piston rod. The upper and lower ends of the block are offset by the rotation of the second rollers to improve the smoothness of the lateral sliding. Finally, during the lateral sliding of the block, the lower end of the block is supported by the first roller towards the base. The rotation of the first and second rollers, combined with the restriction and guidance of the sliding rail, allows the carbon rod to slide smoothly and stably along the bracket, improving the clamping effect. At the same time, it will not cause the air planer position to shift due to the lack of restriction. The user does not need to rely on their own arm strength to continuously control the movement trajectory of the block, making it easier for the user to use and improving the air planing effect.

[0024] The present invention will be further described below with reference to specific embodiments.

[0025] like Figure 1 As shown, an auxiliary device for piston rod air gouging in this embodiment includes a base 1, a support frame 12 is provided on one side of the outer side of the base 1, and a sliding rail 9 is provided on one side of the inner side of the base 1. A sliding block 10 is provided at the lower end of the outer side of the support frame 12 facing the interior of the sliding rail 9, and the sliding block 10 is embedded in the interior of the sliding rail 9 and slidably connected to the interior of the sliding rail 9. When sliding laterally and adjusting the position of the carbon rod, the sliding stability can be improved by sliding the sliding block 10 in the sliding rail 9. The improved stability can improve the air gouging effect.

[0026] Among them, a pair of second rollers 22 are horizontally arranged at both the upper and lower ends of the outer side of the sliding block 10, and the center of the second rollers 22 is rotatably connected to the inside of the sliding block 10. The outer wall of the second rollers 22 contacts the inner wall of the sliding rail 9. When the sliding block 10 slides horizontally, the rotation of the second rollers 22 can reduce friction.

[0027] In addition, the two sides of the lower end of the sliding block 10 are respectively provided with first rollers 11 facing the base 1. While one end of the sliding block 10 slides in the sliding rail 9, the sliding block 10 exposed outside the sliding rail 9 will slide on the upper end of the base 1 through the first rollers 11.

[0028] In order to clamp and fix the piston rod and facilitate the lifting of the repaired piston rod, thereby improving the stability of the piston rod during repair, a bracket 2 is provided at the upper end of the base 1. First clamping plates 4 are provided on both sides of the upper end of the bracket 2. When placing the piston rod, the lower end of the piston rod first contacts and is placed on the upper end of the bracket 2, and the first clamping plates 4 can move toward the bracket 2 through transmission to achieve clamping.

[0029] The other side of the two first clamping plates 4 is welded and fixed by the transmission frame 5. The transmission frame 5 has a first threaded rod 6 running through it, and the outside of the first threaded rod 6 is threadedly engaged with the through position of the transmission frame 5. By manually turning the first threaded rod 6, the two first clamping plates 4 can be adjusted to a horizontal position, thereby clamping or releasing the welded piston rod.

[0030] In addition, such as Figure 6 As shown, in order to directly lift the piston rod placed inside the bracket 2 and facilitate its removal, the bracket 2 is provided with a movable groove 3. The movable groove 3 passes through the bracket 2 and extends into the interior of the base 1. A support plate 8 is arranged along the movable groove 3 inside the base 1, and the support plate 8 is welded and fixed to the transmission frame 5. During the process of the transmission frame 5 driving the first clamping plate 4 to move laterally, the transmission frame 5 will also drive the support plate 8 to move. When the support plate 8 moves longitudinally, the support plate 8 will extend from the movable groove 3 and lift the clamped piston rod. When the first clamping plate 4 moves toward the bracket 2 and clamps the piston rod, the support plate 8 will be stored inside the base 1 through the movable groove 3.

[0031] In order to adjust the position of the carbon rod used for air gouging, a sliding rod 14 is slidably provided on the upper part of the support frame 12. The sliding rod 14 and the support frame 12 are connected by a pin. When the sliding rod 14 is adjusted to a horizontal position, the pin passes through the sliding rod 14 and the support frame 12 in sequence and can fix the extension distance of the sliding rod 14.

[0032] Secondly, such as Figure 2 and Figure 3As shown, a fourth threaded rod 18 is provided at one end of the sliding rod 14, and the fourth threaded rod 18 is welded and fixed to the sliding rod 14. A connecting plate 15 is provided on one side of the fourth threaded rod 18, and the center of the connecting plate 15 is rotatably connected to the outside of the fourth threaded rod 18. A transmission block 19 is provided on one side of the fourth threaded rod 18, and the inside of the transmission block 19 is threaded with the outside of the fourth threaded rod 18. After the angle is adjusted, the transmission block 19 can rotate outside the fourth threaded rod 18 and move toward the connecting plate 15. The movement toward the connecting plate 15 can fix the connecting plate 15 after the angle is adjusted.

[0033] In addition, such as Figure 4 As shown, a second clamping plate 16 is provided on one side of the outer side of the connecting plate 15. A third threaded rod 17 is provided through the interior of the second clamping plate 16, and one end of the third threaded rod 17 is rotatably connected to the connecting plate 15. The outer side of the third threaded rod 17 is threadedly engaged with the through position of the second clamping plate 16. After the third threaded rod 17 is rotated, the second clamping plate 16 will move toward the connecting plate 15 and adjust the distance between the connecting plate 15 and the second clamping plate 16. The carbon rod used for air gouging can be clamped by adjusting the distance between the connecting plate 15 and the second clamping plate 16.

[0034] In order to identify the angle adjustment of the connecting plate 15, a pointer 21 is provided on one side of the outer wall of the connecting plate 15, and the pointer 21 is welded and fixed to the connecting plate 15. An angle reference table 20 is provided around the outer wall of the connecting plate 15. When the connecting plate 15 rotates and rotates with the fourth threaded rod 18 as the center, the pointer 21 rotates outside the angle reference table 20 and adjusts the angle to know the current angle of the carbon rod and the air gouging.

[0035] To improve the stability of the third threaded rod 17 and the first threaded rod 6 during rotation, a limiting rod 7 is provided at one end of the third threaded rod 17 and at both ends of the first threaded rod 6. The limiting rod 7 is slidably connected to the corresponding second clamping piece 16 and the transmission frame 5. By limiting one of the limiting rods 7, the first threaded rod 6 can rotate and generate relative movement with the transmission frame 5, causing the transmission frame 5 to change from rotational motion to longitudinal linear motion. By limiting the other limiting rod 7, the third threaded rod 17 can rotate and generate relative movement with the second clamping piece 16, causing the second clamping piece 16 to change from rotational motion to longitudinal linear motion.

[0036] To further adjust the welding position of the carbon rod, the lower end of the support frame 12 is embedded inside the sliding block 10 and slidably connected to the interior of the sliding block 10, such as... Figure 7As shown, a second threaded rod 13 is horizontally inserted through the support frame 12 and the sliding block 10. The outside of the second threaded rod 13 is threadedly engaged with the through position of the support frame 12. The position of the carbon rod can be adjusted laterally by rotating the second threaded rod 13.

[0037] To facilitate lateral sliding and adjustment of the piston rod position, such as Figure 5 As shown, a third roller 24 is provided inside the bracket 2 corresponding to the position of the first clamping piece 4. The rotation of the third roller 24 can facilitate the lateral sliding of the clamped piston rod.

[0038] To assist in the removal of metal debris generated during air gouging, a blower 23 is bolted to one side of the connecting plate 15. The blower 23 adjusts as the angle of the connecting plate 15 and the second clamping plate 16 is adjusted. After being powered on and turned on, it continuously blows the piston rod gap repair position, blowing the debris out of the processing position and improving the processing effect.

[0039] Working principle: When using the device to air-goug the gaps and repair areas of the piston rod, the piston rod is placed between the bracket 2 and the first clamping plate 4. The first threaded rod 6 is rotated clockwise, and the transmission frame 5 drives the first clamping plate 4 towards the base 1, clamping and fixing the piston rod. The carbon rod is placed between the second clamping plate 16 and the connecting plate 15. Through the rotation of the third threaded rod 17 and its relative movement with the second clamping plate 16, the carbon rod is clamped by the second clamping plate 16 and the connecting plate 15. The carbon rod acts as an electrode, contacting the repair position of the clamped piston rod to ignite an arc, generating an electric arc between the carbon rod and the piston rod. The high temperature generated by the arc causes the piston rod to... The surface metal melts rapidly. The blower 23 is activated to draw in external gas and blow it toward the repair position. The air blows away the molten metal fragments, forming a groove. While performing continuous air gouging along a strip-shaped trajectory, the handle at the rear end of the second threaded rod 13 is held and the carbon rod slides along the sliding rail 9. The sliding block 10 slides within the sliding rail 9 through the rotation of the second roller 22. At the same time, the sliding block 10 rotates on the upper end of the base 1 through the first roller 11. When the air gouging of the piston rod is completed, the first threaded rod 6 is rotated counterclockwise, causing the first clamping plate 4 to move away from the bracket 2. The support plate 8 extends from the movable groove 3 and lifts the repaired piston rod, making it easy for the user to remove the piston rod.
