Description

Technical Field

[0001] This utility model relates to the field of hydraulic actuator repair technology, specifically a hydraulic actuator sealing groove repair device. Background Technology

[0002] A hydraulic actuator is a hydraulic execution mechanism that converts hydraulic energy from a hydraulic source into mechanical energy. It can also be servo controlled as needed via a built-in displacement sensor or limit switch. A sealing groove is a common and important structure in mechanical equipment, primarily used for sealing. Problems with the sealing groove can easily cause equipment malfunctions and even affect production safety. Current methods for repairing sealing grooves mainly involve grinding.

[0003] For example, announcement number CN112963659A, entitled "A Device for Repairing Defects in the Sealing Groove of a Vehicle Hydraulic System Pipeline Joint," includes a base; fixed blocks are fixedly provided on both the left and right end faces of the base, and the fixed blocks are equipped with a pressing mechanism, a power mechanism, and a post-processing mechanism; the device for repairing defects in the sealing groove of a vehicle hydraulic system pipeline joint in this technical solution can quickly check whether the diameter of the pipe clamp inside the pipe joint is qualified and maintain the stability of the pipe joint after it is clamped, ensuring the accuracy of subsequent post-processing of the pipe joint, effectively ensuring the quality of post-processing, and avoiding the traditional manual process of scraping off burrs with blades by mechanical means, avoiding the unstable quality phenomenon of manual deburring, and preventing burrs in the sealing ring groove from affecting the sealing performance of the subsequently assembled sealing ring, greatly increasing the safety of the vehicle hydraulic system.

[0004] However, the existing sealing groove repair device has the following defects when in use: 1. The repair device can only drive one repair head to perform grinding, resulting in low overall efficiency; 2. The spring clamping method has poor stability, and the object is prone to displacement due to vibration during repair. Therefore, it does not meet the current needs. In response, a hydraulic actuator sealing groove repair device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic actuator sealing groove repair device to solve the problem that the existing repair devices mentioned in the background art can only drive one repair head to perform grinding, resulting in low overall efficiency, poor stability, and the object is prone to displacement due to vibration during repair.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic actuator sealing groove repair device, comprising: a platform, on both sides of the upper surface of the platform are displacement components, multiple sets of clamping and limiting components are installed above the displacement components, a frame is installed at the middle position of the upper surface of the platform, the clamping end of the clamping and limiting component extends into the frame, and a repair component is installed at one end of the frame.

[0007] Preferably, the repair component includes an assembly frame, on the outer wall of the assembly frame a drive motor is mounted, the output end of the drive motor is connected to a main gear via a shaft, three sets of secondary gears are mounted in a ring around the main gear, and an internal gear ring is mounted around the secondary gears, the main gear drives the secondary gears to rotate and displace on the internal gear ring.

[0008] Preferably, one end of the main gear is connected to a turntable via a shaft, and three sets of annularly spaced connecting rods are provided on the outer wall of the turntable. A grinding head is installed at one end of each connecting rod, and one end of the secondary gear is connected to the connecting rod via a shaft.

[0009] Preferably, the clamping and limiting component includes a bracket, an electric telescopic rod is mounted on the outer wall of the bracket, and an arc-shaped clamp is mounted on the telescopic end of the electric telescopic rod.

[0010] Preferably, an arc-shaped rubber strip is provided on the inner wall of the arc-shaped clamp.

[0011] Preferably, the displacement component includes an assembly groove, a forward lead screw is installed inside the assembly groove, a reverse lead screw is installed at one end of the forward lead screw, a lead screw motor is installed at the other end of the forward lead screw, and lead screw sliders are installed on the outer walls of both the forward lead screw and the reverse lead screw.

[0012] Preferably, a cover plate is installed above the assembly slot, and a slide is installed above the cover plate. The slide is connected to the lead screw slider by bolts.

[0013] Preferably, side plates are provided on both sides of the frame, and strip-shaped channels are opened on the outer wall of the side plates. A cover plate is installed on the top between the two side plates. A dust collection and filter box is installed on the outer wall of the frame near the repair component, and multiple fans are installed on the top of the dust collection and filter box.

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

[0015] (1) In this utility model, the main gear is driven to rotate by the drive motor. The main gear meshes with the three sets of auxiliary gears around it. The auxiliary gears are located between the internal gear ring and the main gear. When the main gear rotates, the auxiliary gears are driven to move at the internal gear ring. The main gear drives the external turntable to rotate through the shaft connection. The rotation of the turntable enables the three sets of grinding heads to rotate periodically in the sealing groove. The position in the sealing groove is changed by the simultaneous rotation of the three sets. In addition, the auxiliary gear drives the connecting rod and the grinding head to rotate, and rotates and grinds the sealing groove to remove the burrs in the sealing groove. The above structure can drive multiple grinding heads to grind and repair the sealing groove at one time, which is more efficient and more convenient for users.

[0016] (2) In this utility model, the electric telescopic rod is used to drive the arc-shaped clamp to move. When the electric telescopic rod extends forward, the arc-shaped clamp moves forward to limit and clamp the cylindrical parts such as hydraulic actuators. The rubber strip is used to contact the outer wall of the hydraulic actuator. It has good elasticity and can deform. It can also prevent the arc-shaped clamp from directly contacting the surface of the hydraulic actuator, thus avoiding wear on the surface of the hydraulic actuator. The above structure can ensure that the hydraulic actuator will not shift due to vibration during the repair process, thus improving the stability of placement.

[0017] (3) In this utility model, the lead screw motor is used to drive the lead screw slider to move on the forward lead screw and the reverse lead screw. Due to the design of the forward thread and the reverse thread, the two lead screw sliders can move towards each other and away from each other, thereby achieving the effect of simultaneously driving the two clamping limiters to move. By moving and adjusting the position of the clamping limiters, it is convenient to change their clamping position according to the length of the hydraulic actuator, thus improving flexibility.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-4 This utility model provides an embodiment of a hydraulic actuator sealing groove repair device, comprising: a platform 1, displacement components 2 installed on both sides of the upper surface of the platform 1, multiple sets of clamping and limiting members 3 installed above the displacement components 2, a frame 5 installed at the middle position of the upper surface of the platform 1, the clamping ends of the clamping and limiting members 3 extending into the frame 5, and a repair component 4 installed at one end of the frame 5. Specifically, the repair component 4 includes an assembly frame 401, a drive motor 402 installed on the outer wall of the assembly frame 401, and the drive motor 402... The output end is connected to a main gear 408 via a shaft. Three sets of secondary gears 407 are installed around the main gear 408 in a ring at intervals. An internal gear ring 406 is installed around the secondary gears 407. The main gear 408 drives the secondary gears 407 to rotate and move on the internal gear ring 406. One end of the main gear 408 is connected to a turntable 403 via a shaft. Three sets of connecting rods 404 are arranged in a ring at intervals on the outer wall of the turntable 403. A grinding head 405 is installed at one end of the connecting rods 404. One end of the secondary gear 407 is connected to the connecting rods 404 via a shaft.

[0025] The main gear 408 is driven to rotate by the drive motor 402. The main gear 408 meshes with three sets of auxiliary gears 407 around it. The auxiliary gears 407 are located between the internal gear ring 406 and the main gear 408. When the main gear 408 rotates, the auxiliary gears 407 are driven to move at the internal gear ring 406. The main gear 408 drives the external turntable 403 to rotate through the shaft connection. The rotation of the turntable 403 enables the three sets of grinding heads 405 to rotate periodically in the sealing groove. The position of the three sets in the sealing groove is changed by rotating the three sets at the same time. In addition, the auxiliary gears 407 drive the connecting rod 404 and the grinding head 405 to rotate, and perform rotational grinding and repair in the sealing groove to remove burrs in the sealing groove. The above structure can drive multiple grinding heads 405 to grind and repair the sealing groove at one time, which is more efficient and more convenient for users.

[0026] Please see Figure 3 The clamping and limiting component 3 includes a bracket 304. An electric telescopic rod 301 is installed on the outer wall of the bracket 304. An arc-shaped chuck 302 is installed at the telescopic end of the electric telescopic rod 301. An arc-shaped rubber strip 303 is provided on the inner wall of the arc-shaped chuck 302. The electric telescopic rod 301 is used to drive the arc-shaped chuck 302 to move. When the electric telescopic rod 301 extends forward, the arc-shaped chuck 302 moves forward to limit and clamp the cylindrical component such as the hydraulic actuator. The rubber strip 303 is used to contact the outer wall of the hydraulic actuator. It has good elasticity and can deform. It can also prevent the arc-shaped chuck 302 from directly contacting the surface of the hydraulic actuator, thus avoiding wear on the surface of the hydraulic actuator.

[0027] Please see Figure 3 The displacement component 2 includes an assembly groove 207, inside which a forward lead screw 201 is installed. A reverse lead screw 202 is installed at one end of the forward lead screw 201, and a lead screw motor 203 is installed at the other end of the forward lead screw 201. Lead screw sliders 204 are installed on the outer walls of both the forward lead screw 201 and the reverse lead screw 202. A cover plate 206 is installed above the assembly groove 207, and a slide table 205 is installed above the cover plate 206. The slide table 205 is connected to the lead screw sliders 204 by bolts. The lead screw motor 203 is used to drive the lead screw sliders 204 to move on the forward lead screw 201 and the reverse lead screw 202. Due to the design of the forward and reverse threads, the two lead screw sliders 204 can move closer and further away from each other, thereby achieving the effect of simultaneously driving the two clamping limiters 3 to move. By moving and adjusting the position of the clamping limiters 3, it is convenient to change their clamping position according to the length of the hydraulic actuator.

[0028] Please see Figure 2The frame 5 has side plates 504 on both sides, and strip channels 505 are opened on the outer wall of the side plates 504. A cover plate 503 is installed on the top between the two side plates 504. A dust collection filter box 501 is installed on the outer wall of the frame 5 near the repair component 4. Multiple fans 502 are installed on the top of the dust collection filter box 501. The frame 5 is formed by the two side plates 504 and the cover plate 503. When placing the hydraulic actuator, the cover plate 503 can be removed for easy placement by the user. During repair, the fans 502 pull the dust generated during the repair process into the dust collection filter box 501 to achieve the effect of dust reduction. The telescopic end of the clamping limiter 3 moves within the channel 505 without affecting its normal movement operation.
