Description

Technical Field

[0001] This utility model is specifically a device for repairing surface scratches on a beryllium copper piston rod, belonging to the technical field of beryllium copper piston rods. Background Technology

[0002] Beryllium copper piston rod is a piston rod made of an alloy material. The piston rod is the connecting part that supports the piston to do work. It is mostly used in the moving parts of hydraulic cylinders and pneumatic cylinders. It is a moving part with frequent movement and high technical requirements. When scratches appear on the surface of the beryllium copper piston rod, the surface of the piston rod needs to be polished to repair the scratches. Chinese Patent Publication No. CN222200105U discloses a piston rod surface polishing device, including a clamping device support plate, a first slide rail, a servo motor, a first clamping device, an annular support plate, a turntable, a second clamping device, a polishing disc support plate, a second slide rail, a third slide rail, a polishing disc motor, and a polishing disc. This application achieves stable rotation of the piston rod by rotating the first clamping device with the servo motor, causing the clamped piston rod to rotate and driving the turntable connected to the second clamping device to rotate. The polishing disc motor rotates the polishing disc, thus achieving the polishing operation of the piston rod. Slowly moving the clamping device support plate allows for polishing of different sections of the piston rod. This invention can polish the surfaces of piston rods of various diameters and lengths without dead angles, reducing surface roughness and improving precision. In the existing technology, during the piston rod polishing and repair process, the workpiece needs to be disassembled and the installation position adjusted in order to complete the full surface grinding without dead angles. This intermittent operation not only interrupts the continuous operation process, but also increases the time for disassembly and positioning. At the same time, the positioning deviation may be caused by repeated clamping, which affects the dimensional accuracy and surface consistency after polishing. The overall operation efficiency and processing stability are limited, resulting in low polishing and repair efficiency and reducing the practicality of the device. Summary of the Invention

[0003] The purpose of this utility model is to provide a beryllium copper piston rod surface scratch repair device to solve the above-mentioned problems, so as to solve the problem that repeated clamping causes positioning deviation, which affects the dimensional accuracy and surface consistency after polishing, limits the overall operation efficiency and processing stability, resulting in low polishing repair efficiency and reduced practicality of the device.

[0004] This utility model is achieved through the following technical solution: a beryllium copper piston rod surface scratch repair device, including a worktable, support rods fixed at the four corners of the bottom of the worktable, a through hole through the center of the top of the worktable, a polishing mechanism connected to the top of the worktable, and a lifting mechanism connected to the bottom of the worktable.

[0005] Preferably, the polishing mechanism includes a mounting ring fixed to the center of the top of the worktable, a turntable rotating within the inner cavity of the mounting ring, a vortex groove evenly formed on the top of the turntable, a gear ring fixed to the outer wall of the turntable, a drive motor fixed to the top edge of the worktable, a transmission gear fixed to the end of the output shaft of the drive motor, a sliding groove evenly formed through the top of the mounting ring, a slider sliding inside the sliding groove, a connecting shaft fixed to the center of the bottom of the slider, a mounting frame fixed to the top of the slider, a rotating motor fixed to the center of the bottom of the inner cavity of the mounting frame, a polishing roller sleeved on the outer side of the output shaft of the rotating motor, a fastening nut screwed to the end of the outer wall of the output shaft of the rotating motor, and limit rods symmetrically fixed between the two sides of the inner cavity of the sliding groove.

[0006] Preferably, the outer wall of the gear ring is meshed with the outer wall of the transmission gear. When the transmission gear rotates, it drives the gear ring to rotate, causing the turntable to rotate. The connecting shaft is located inside the vortex groove. When the turntable rotates, the vortex groove deflects, causing the connecting shaft to move inside the vortex groove, gradually bringing the connecting shaft closer to the center of the turntable.

[0007] Preferably, the outer wall of the slider is in contact with the inner wall of the groove, and the slider slides on the outside of the limiting rod to limit the slider so that the slider can only slide inside the groove.

[0008] Preferably, the lifting mechanism includes slide rods symmetrically fixed to the bottom of the workbench, a slide plate sliding on the outer side of the slide rod, connecting rods fixed at the middle of both sides of the slide plate, a top rod fixed at the middle of the top of the slide plate, an electric telescopic rod fixed at the middle of the bottom edge of the workbench, a movable frame fixed at the end of the output shaft of the electric telescopic rod, and inclined slots through both sides of the movable frame.

[0009] Preferably, the lifting mechanism further includes mounting plates symmetrically fixed to the bottom edge of the workbench, and L-shaped rods fixed to the top of both sides of the movable frame.

[0010] Preferably, the L-shaped rod passes through one side of the mounting plate, and the L-shaped rod is slidably connected to the mounting plate. The L-shaped rod and the fixed plate cooperate to limit the movement of the mobile frame, so that the mobile frame can move stably.

[0011] Preferably, the connecting rod slides inside the inclined groove. When the moving frame moves, it drives the inclined groove to move, causing the connecting rod to move inside the inclined groove. The center of the top rod coincides with the center of the through hole, allowing the top cover to move up and down at the center of the through hole, which facilitates lifting the piston rod.

[0012] This utility model provides a device for repairing surface scratches on a beryllium copper piston rod, which has the following beneficial effects: 1. This application, through the setting of the polishing mechanism, involves passing the piston rod through the mounting ring, starting the drive motor, driving the transmission gear to rotate, thereby causing the gear ring to drive the turntable to rotate, causing the vortex groove to deflect, thus causing the connecting shaft to move inside the vortex groove. The connecting shaft drives the slider to gradually approach the center of the turntable, driving the mounting frame to move, so that the polishing roller contacts the piston rod and clamps the piston rod. Then, the rotation motor is started, driving the polishing roller to rotate, causing the piston rod to rotate and polish the piston rod. Using a lifting mechanism, the piston rod is gradually lifted to change the polishing position, preventing the need to stop and flip to change the polishing position, facilitating continuous polishing and repair, improving repair efficiency, and enhancing the practicality of the device.

[0013] 2. This application, through the setting of a lifting mechanism, moves the moving frame by activating the electric telescopic rod, causing the connecting rod to move inside the inclined groove, thereby driving the slide plate to move outside the slide rod, changing the position of the top rod, thus facilitating adjustment according to the length of the piston rod, ensuring that the initial top of the piston rod is below the polishing roller, avoiding insufficient polishing, facilitating adjustment according to the piston rod, and improving the applicability of the device.

Through the setting of the polishing mechanism 4, the piston rod passes through the mounting ring 401, the drive motor 405 is started, and the transmission gear 406 is driven to rotate, so that the gear ring 404 drives the turntable 402 to rotate, causing the vortex groove 403 to deflect, so that the connecting shaft 409 moves inside the vortex groove 403, so that the connecting shaft 409 drives the slider 408 to gradually approach the center of the turntable 402, driving the mounting frame 410 to move, so that the polishing roller 412 contacts the piston rod and clamps the piston rod.

Example 2

[0019] Please refer to it again. Figure 5The lifting mechanism 5 includes sliding rods 501 symmetrically fixed to the bottom of the worktable 1, a sliding plate 502 sliding on the outer side of the sliding rods 501, connecting rods 503 fixed to the middle of both sides of the sliding plate 502, a top rod 504 fixed to the middle of the top of the sliding plate 502, an electric telescopic rod 505 fixed to the middle of the bottom edge of the worktable 1, a movable frame 506 fixed to the end of the output shaft of the electric telescopic rod 505, and inclined slots 507 penetrating both sides of the movable frame 506; the lifting mechanism 5 also includes mounting plates 508 symmetrically fixed to the bottom edge of the worktable 1, and L-shaped rods 509 fixed to the top of both sides of the movable frame 506; the L-shaped rods 509 penetrate the mounting plates 508 and 509.

The connecting shaft 409 drives the slider 408 to gradually approach the center of the turntable 402, which in turn moves the mounting frame 410, causing the polishing roller to... 412 contacts the piston rod and clamps it. Then, the rotating motor 411 is started, which drives the polishing roller 412 to rotate, causing the piston rod to rotate and polish it. At the same time, the electric telescopic rod 505 is started, which moves the moving frame 506 and the connecting rod 503 inside the inclined groove 507.
