Description

Technical Field

[0001] This utility model relates to the field of cylinder repair technology, specifically to a device for repairing and reconstructing the inner surface of an actuator cylinder. Background Technology

[0002] Actuators are widely used in industry. Their cylinder inner surface, as a critical working surface, is subjected to harsh conditions such as high pressure, high-speed friction, and media corrosion over long periods, making it highly susceptible to wear, scratches, and corrosion pits. This damage not only reduces the actuator's sealing performance, leading to leaks, but also affects its motion accuracy and stability, shortens its service life, and can even cause safety accidents.

[0003] A search revealed a utility model patent with Chinese patent publication number CN213670069U, which discloses a glue-applying device for repairing hydraulic cylinder barrels. The device includes a base, a clamping assembly, a glue-applying assembly, and a rotating assembly. The base has a sliding groove on one side of its upper end, and the clamping assembly is adapted to fit within the sliding groove. The glue-applying assembly has a glue-applying assembly on one side, and a delivery pipe is connected to the glue-applying assembly. The other end of the delivery pipe is connected to a repair glue storage tank, and a heater and a drive pump are installed on the delivery pipe.

[0004] The aforementioned device smooths the repair adhesive using a scraper, but its position is fixed, making it unsuitable for different sizes. When put into use, different sizes of devices are required, resulting in high operating costs and room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a device for repairing and reconstructing the inner surface of an actuator cylinder, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for repairing and reconstructing the inner surface of an actuator cylinder, comprising a mounting frame, a support frame fixedly connected to the top outer wall of the mounting frame, a repair component installed inside the support frame, the repair component comprising a movable frame slidably inserted inside the support frame, a horizontally arranged bidirectional lead screw rotatably connected to one end of the bottom of the movable frame, a scraper and a mounting block respectively threaded at the two ends of the bidirectional lead screw, two horizontally arranged limiting strips fixedly connected to the bottom of the outer walls on both sides of the movable frame, the scraper and the mounting block respectively slidably sleeved on the outside of the two limiting strips on one side, and a repair agent nozzle fixedly installed on the top outer wall of the mounting block.

[0007] The position of the scraper and nozzle can be adjusted according to the size of the cylinder, thereby ensuring that the adhesive layer attached to the inner surface of the cylinder can reach a relatively flat state, which is beneficial to improving the adaptability of the device. The position of the scraper and the mounting block is adjusted according to the size of the cylinder to be repaired. The double screw is driven to rotate inside the moving frame by the knob. The scraper, which is sleeved outside the two limit strips, cannot rotate. The double screw can then drive the scraper to move to the appropriate size position, so that the adhesive layer scraped by it can achieve the required smoothness. Similarly, the mounting block will also be driven to move closer to the cylinder.

[0008] As a further preferred embodiment of this technical solution, a transmission assembly is installed on the outside of the support frame. The transmission assembly includes a motor fixedly installed on the top outer wall of the support frame. A transmission rod is coaxially fixed to the output end of the motor. A transmission gear is coaxially fixed to one end of the bottom of the transmission rod. A fixing assembly is installed inside the mounting frame. The fixing assembly includes a receiving plate rotatably connected inside the mounting frame. A gear ring is coaxially fixed to the top outer wall of the receiving plate. The transmission gear meshes with the gear ring.

[0009] As a further preferred embodiment of this technical solution, a vertically arranged lead screw is rotatably connected inside the support frame. The lead screw is threaded inside the movable frame. A sprocket is coaxially fixed at one top end of the lead screw and the output end of the motor, and the two sprockets are fitted with the same chain.

[0010] As a further preferred embodiment of this technical solution, the top outer wall of the receiving plate is provided with several equally spaced limiting grooves. Each of the limiting grooves is slidably connected to a moving block. Each of the limiting grooves is rotatably connected to a lead screw. The lead screws are threaded into the moving blocks. One end of each lead screw is coaxially fixed to a bevel gear. The receiving plate is rotatably connected to a bevel gear. The bevel gears mesh with the bevel gears. A drive disc is coaxially fixed to one bottom end of the bevel gear.

[0011] The drive disc drives the second bevel gear to rotate inside the receiving disc. The second bevel gear meshes with the first bevel gear, causing the first bevel gear to rotate synchronously. Under the drive of the second lead screw, the moving blocks are driven to move closer to each other along the limit slide groove, and the cylinder is firmly restricted to the middle position of the receiving disc.

[0012] As a further preferred embodiment of this technical solution, baffles are provided on the inner walls of the sides of the several moving blocks that are close to each other, and several clearance grooves adapted to the baffles are provided on the outer wall of the top of the receiving plate.

[0013] As a further preferred embodiment of this technical solution, a stabilizing sleeve is fixedly connected to the inner wall of one side of the support frame, and the transmission rod is rotatably connected inside the stabilizing sleeve.

[0014] As a further preferred embodiment of this technical solution, a contact plate is provided on the side of each of the several moving blocks that are close to each other. The several contact plates are made of TPE material, and anti-slip pads are provided on the side of each of the blocks that are close to each other.

[0015] As a further preferred embodiment of this technical solution, the bottom inner wall of the mounting bracket is provided with a plurality of mounting holes.

[0016] This utility model provides a device for repairing and reconstructing the inner surface of an actuator cylinder, which has the following beneficial effects:

[0017] (1) By setting up the repair component, the position of the scraper and the nozzle can be adjusted according to the size of the cylinder, so as to ensure that the adhesive layer attached to the inner surface of the cylinder can reach a relatively flat state, which is conducive to improving the adaptability of the device. The position of the scraper and the mounting block is adjusted according to the size of the cylinder to be repaired. The double screw is driven to rotate inside the moving frame by the knob. The scraper sleeved outside the two limit strips cannot rotate. The double screw can drive the scraper to move to the appropriate size position, so that the adhesive layer scraped by it can achieve the required smoothness. Similarly, the mounting block will also be driven to approach the cylinder.

[0018] (2) By setting a fixed component, the drive disk drives the bevel gear two to rotate inside the receiving disk. The bevel gear two drives the bevel gear to rotate together through meshing. The bevel gear one drives the lead screw two connected to it to rotate synchronously. Under the drive of the lead screw two, the moving blocks will be driven to move closer to each other along the limiting slide groove, and the cylinder can be firmly restricted in the middle position of the receiving disk.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 1 and Figure 3 As shown, in this embodiment, an actuator cylinder inner surface repair and reconstruction device includes a mounting frame 1. A support frame 2 is fixedly connected to the top outer wall of the mounting frame 1. A repair component 3 is installed inside the support frame 2. The repair component 3 includes a movable frame 301 that is slidably inserted into the support frame 2. A horizontally arranged bidirectional lead screw 302 is rotatably connected to one end of the bottom of the movable frame 301. A scraper 304 and a mounting block 305 are respectively threaded at the two ends of the bidirectional lead screw 302. Two horizontally arranged limiting strips 303 are fixedly connected to the bottom of the outer walls on both sides of the movable frame 301. The scraper 304 and the mounting block 305 are respectively slidably sleeved on the outside of the two limiting strips 303 on one side. A repair agent nozzle is fixedly installed on the top outer wall of the mounting block 305 (the repair agent used is, for example, J-111 metal repair agent: it has similar strength and hardness to metal, can be cured at room temperature or under heating conditions, and after repair, the required size and surface roughness can be achieved by turning, grinding and other processing methods).

[0026] Adjust the positions of the scraper 304 and the mounting block 305 according to the size of the cylinder to be repaired. Drive the double-acting screw 302 to rotate inside the moving frame 301 by the knob. The scraper 304, which is sleeved on the outside of the two limit strips 303, cannot rotate. The double-acting screw 302 can then drive the scraper 304 to move to the appropriate size position so that the adhesive layer scraped by it can achieve the required smoothness. Similarly, the mounting block 305 will also be driven to approach the cylinder.

[0027] like Figure 1 and Figure 4As shown, a transmission assembly 4 is installed on the outside of the support frame 2. The transmission assembly 4 includes a motor 404 fixedly installed on the top outer wall of the support frame 2. A transmission rod 401 is coaxially fixed to the output end of the motor 404. A transmission gear 403 is coaxially fixed to one end of the bottom of the transmission rod 401. A fixing assembly 5 is installed inside the mounting frame 1. The fixing assembly 5 includes a receiving plate 501 rotatably connected inside the mounting frame 1. A gear ring 402 is coaxially fixed to the top outer wall of the receiving plate 501. The transmission gear 403 meshes with the gear ring 402.

[0028] The support frame 2 is rotatably connected to a vertically arranged lead screw 405. The lead screw 405 is threadedly connected to the inside of the movable frame 301. A sprocket is coaxially fixed at the top end of the lead screw 405 and the output end of the motor 404, and the two sprockets are fitted with the same chain.

[0029] The motor 404 at the top of the support frame 2 is started. The motor 404 drives the transmission rod 401 to rotate. The transmission rod 401 drives the transmission gear 403 to rotate. The transmission gear 403 drives the gear ring 402 to rotate through meshing. The gear ring 402 drives the receiving plate 501 and the cylinder on top of it to rotate. At the same time, the spray gun is started to spray the repair agent. The repair agent is then sprayed onto the inner wall of the cylinder. When the motor 404 is running, the lead screw 405 rotates synchronously with the cooperation of the sprocket and chain. The lead screw 405 drives the moving frame 301 to move at a uniform speed along the support frame 2, which helps to improve the uniformity of the repair agent distribution.

[0030] like Figure 1 and Figure 2 As shown, the top outer wall of the receiving plate 501 is provided with several equally spaced limiting grooves 502. Each limiting groove 502 is slidably connected to a moving block 503. Each limiting groove 502 is rotatably connected to a lead screw 505. Each lead screw 505 is threaded into the moving block 503. One end of each lead screw 505 is coaxially fixed to a bevel gear 506. A bevel gear 507 is rotatably connected inside the receiving plate 501. Each bevel gear 506 meshes with the bevel gear 507. A drive disc 508 is coaxially fixed to one end of the bottom of the bevel gear 507.

[0031] The drive disc 508 drives the second bevel gear 507 to rotate inside the receiving disc 501. The second bevel gear 507 drives the first bevel gear 506 to rotate in the same direction through meshing. The first bevel gear 506 drives the second lead screw 505 connected to it to rotate synchronously. Under the drive of the second lead screw 505, the moving blocks 503 are driven to move closer to each other along the limiting slide groove 502, and the cylinder can be firmly restricted to the middle position of the receiving disc 501.

[0032] like Figure 1 and Figure 2As shown, baffles are provided on the inner walls of the sides of several moving blocks 503 that are close to each other, and several clearance grooves adapted to the baffles are provided on the top outer wall of the receiving plate 501. This can prevent the repair agent from falling onto the top of the screw 505 through the limiting slide groove 502 and ensure that the movement of the moving blocks 503 is not affected.

[0033] like Figure 4 As shown, a stabilizing sleeve is fixedly connected to the inner wall of one side of the support frame 2, and the transmission rod 401 is rotatably connected inside the stabilizing sleeve, which helps to improve the stability of the transmission rod 401.

[0034] like Figure 1 and Figure 2 As shown, a contact plate 504 is provided on the side of several movable blocks 503 that are close to each other. The contact plates 504 are made of TPE material, and anti-slip pads are provided on the side that is close to each other. The contact plates 504 are elastic and can change with the shape of the cylinder for cylinders with larger diameters, which helps to improve the fixing effect.

[0035] like Figure 1 As shown, the bottom inner wall of the mounting bracket 1 has several mounting holes 6. The connector can be passed through the mounting holes 6 to connect and fix the mounting bracket 1 to the external equipment.

[0036] This utility model provides a device for repairing and reconstructing the inner surface of an actuator cylinder, the specific working principle of which is as follows:

[0037] When the device is working, the positions of the scraper 304 and the mounting block 305 are adjusted according to the size of the cylinder to be repaired. The double-acting screw 302 is driven to rotate inside the moving frame 301 by the knob. The scraper 304, which is sleeved on the outside of the two limit bars 303, cannot rotate. The double-acting screw 302 can then drive the scraper 304 to move to the appropriate size position so that the adhesive layer scraped by it can achieve the required smoothness. Similarly, the mounting block 305 will also be driven to approach the cylinder.

[0038] Place the cylinder on top of the receiving plate 501, press the receiving plate 501 to prevent it from rotating, and then turn the drive plate 508 to make it rotate. The drive plate 508 drives the second bevel gear 507 to rotate inside the receiving plate 501. The second bevel gear 507 drives the first bevel gear 506 to rotate in the same direction through meshing. The first bevel gear 506 drives the second lead screw 505 connected to it to rotate synchronously. Under the drive of the second lead screw 505, the moving blocks 503 will be driven to move closer to each other along the limiting slide groove 502. The cylinder can then be firmly restricted in the middle position of the receiving plate 501. Furthermore, the contact plate 504 is elastic and can change with the shape of the cylinder for cylinders with larger diameters, which helps to improve the fixing effect.

[0039] The motor 404 at the top of the support frame 2 is started. The motor 404 drives the transmission rod 401 to rotate. The transmission rod 401 drives the transmission gear 403 to rotate. The transmission gear 403 drives the gear ring 402 to rotate through meshing. The gear ring 402 drives the receiving plate 501 and the cylinder on top of it to rotate. At the same time, the spray gun is started to spray the repair agent. The repair agent is then sprayed onto the inner wall of the cylinder. When the motor 404 is running, the lead screw 405 rotates synchronously with the cooperation of the sprocket and chain. The lead screw 405 drives the moving frame 301 to move at a uniform speed along the support frame 2, which helps to improve the uniformity of the repair agent distribution.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
