Description

Technical Field

[0001] This utility model relates to the field of machining cylinder bodies for linear actuators, and more particularly to a cylinder body clamping device for machining linear actuators. Background Technology

[0002] An actuator is a combination of an actuator and a control valve in an automatic control system. During the machining process, the actuator cylinder is positioned using a fixture to improve machining accuracy and stability.

[0003] The existing cylinder clamping device for machining linear actuators only has a clamping function when in use, and its clamping surface lacks a material unloading function, which makes it impossible to push the machined cylinder part out of the clamping surface, resulting in a relatively slow machining progress.

[0004] Therefore, to address the problem that existing cylinder clamping devices for linear actuator machining only have clamping functions and lack unloading functions on their clamping surfaces, making it impossible to push the machined cylinder parts out of the clamping surface and resulting in slow processing progress, a new cylinder clamping device for linear actuator machining can be designed. By setting a first electric push rod, its telescopic end can push the mounting frame towards one side of the machining cylinder during operation, so that the roller fits against the cylinder. Then, the servo motor is started, and its output end drives the drive gear to rotate during operation. The drive gear, in cooperation with the belt, drives the driven gear to rotate synchronously, thereby driving the roller to rotate. The friction between the roller and the cylinder surface allows the roller to push the cylinder outward when rotating, thus achieving automatic unloading. Utility Model Content

[0005] In order to overcome the problem that the existing cylinder clamping device for machining linear actuators has only clamping function and lacks unloading function on the clamping surface, it is impossible to push the machined cylinder part out of the clamping surface, resulting in a relatively slow machining progress.

[0006] The technical solution of this utility model is as follows: a cylinder clamping device for machining linear actuators, including a worktable; it also includes a mounting frame, rollers, driven gears, belts, servo motors, driving gears, and a first electric push rod. Mounting slots are provided on both the left and right sides of the upper surface of the worktable. A drive assembly is installed inside the mounting slots. A first clamping seat is provided on the front side of the upper surface of the drive assembly, and a second clamping seat is provided on the rear side of the upper surface of the drive assembly. The mounting frame is slidably connected to the rear surface of the first clamping seat. Several rollers are evenly spaced on the upper and lower sides of the inner surface of the mounting frame. A driven gear is provided on the outer surface of the upper shaft of the rollers. A servo motor is located on the bottom left side of the inner surface of the mounting frame. A driving gear is provided at the output end of the servo motor. A belt is fitted onto the outer surfaces of the driven gear and the driving gear. A first electric push rod is provided on the front surface of the first clamping seat. The output end of the first electric push rod passes through the front side wall of the first clamping seat and connects to the front surface of the mounting frame.

[0007] Preferably, by setting a first electric push rod, its telescopic end can push the mounting frame towards one side of the processing cylinder during operation, so that the roller fits against the cylinder. Then, the servo motor is started, and its output end drives the drive gear to rotate during operation. The drive gear, in cooperation with the belt, drives the driven gear to rotate synchronously, thereby driving the roller to rotate. The friction between the roller and the cylinder surface causes the roller to push the cylinder outward when rotating, thus realizing automatic material discharge. This solves the problem that the existing cylinder clamping device for linear actuator processing only has a clamping function and lacks a material discharge function, which makes it impossible to push the processed cylinder part out of the clamping surface, resulting in slow processing progress.

[0008] Preferably, the drive assembly includes a drive motor, a drive gear, a first rack, and a second rack. The drive motor is installed at the position corresponding to the mounting slot on the bottom surface of the worktable. The output end of the drive motor is connected to the drive gear through the bottom of the worktable. The first rack is engaged with the side of the drive gear, and the second rack is engaged with the side of the drive gear away from the first rack. The top surfaces of the two first racks are connected to the bottom surface of the first clamp, and the upper surfaces of the two second racks are connected to the bottom surface of the second clamp.

[0009] Preferably, a second electric push rod is provided at the middle position of the rear surface of the second clamp, and the output end of the second electric push rod passes through the rear side wall of the second clamp and is connected to an auxiliary component.

[0010] Preferably, the auxiliary components include a mounting box and auxiliary shafts; the telescopic end of the second electric push rod is provided with a mounting box, and several equally spaced auxiliary shafts are rotatably connected to the upper and lower sides of the inner surface of the mounting box.

[0011] Preferably, the bottom surface of the workbench is equipped with support legs at the corners, and the bottom of the support legs is equipped with pads.

[0012] Preferably, the upper surface of the worktable has two symmetrical limiting grooves, and the first clamp and the second clamp are slidably connected to the limiting grooves through limiting blocks.

[0013] Preferably, protective pads are provided on the opposite surfaces of the first clamp and the second clamp, and the protective pads are made of rubber.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a first electric push rod, its telescopic end can push the mounting frame towards one side of the processing cylinder during operation, so that the roller fits against the cylinder. Then, the servo motor is started, and its output end drives the drive gear to rotate during operation. The drive gear, in cooperation with the belt, drives the driven gear to rotate synchronously, thereby driving the roller to rotate. The friction between the roller and the cylinder surface causes the roller to push the cylinder outward when rotating, thus realizing automatic material discharge. This solves the problem that the existing cylinder clamping device for linear actuator processing only has a clamping function and lacks a material discharge function, which makes it impossible to push the processed cylinder part out of the clamping surface, resulting in slow processing progress.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6 This utility model provides an embodiment of a cylinder clamping device for machining linear actuators, including a worktable 1; it also includes a mounting frame 5, rollers 6, driven gears 7, belts 8, servo motors 9, driving gears 10, and a first electric push rod 11. Mounting grooves 2 are provided on both the left and right sides of the upper surface of the worktable 1. A drive assembly is installed inside the mounting grooves 2. A first clamping seat 4 is provided on the front side of the upper surface of the drive assembly, and a second clamping seat 12 is provided on the rear side of the upper surface of the drive assembly. The mounting frame 5 is slidably connected to the rear surface of the first clamping seat 4. A plurality of rollers 6 are evenly spaced on the upper and lower sides of the inner surface of the mounting frame 5. A driven gear 7 is provided on the outer surface of the upper shaft of the rollers 6. A servo motor 9 is located on the bottom left side of the inner surface of the mounting frame 5. A driving gear 10 is provided at the output end of the servo motor 9. A belt 8 is fitted onto the outer surfaces of the driven gear 7 and the driving gear 10. The first clamping... A first electric push rod 11 is provided on the front surface of the seat 4. The output end of the first electric push rod 11 passes through the front side wall of the first clamping seat 4 and connects to the front surface of the mounting frame 5. By providing the first electric push rod 11, its telescopic end can push the mounting frame 5 towards one side of the processing cylinder during operation, so that the roller 6 fits against the cylinder. Then, the servo motor 9 is started. During operation, its output end will drive the drive gear 10 to rotate. The drive gear 10, in cooperation with the belt 8, will drive the driven gear 7 to rotate synchronously, thereby driving the roller 6 to rotate. The friction between the roller 6 and the surface of the cylinder makes the roller 6 push the cylinder outward when it rotates, thereby realizing automatic material discharge. This solves the problem that the existing cylinder clamping device for linear actuator processing only has a clamping function and lacks a material discharge function, which makes it impossible to push the processed cylinder part out of the clamping surface, resulting in slow processing progress.

[0025] Please see Figures 1-5In this embodiment, the driving assembly includes a drive motor 31, a drive gear 32, a first rack 33, and a second rack 34. Drive motors 31 are installed on the bottom surface of the worktable 1 at positions corresponding to the mounting slots 2. A drive gear 32 is installed through the bottom of the worktable 1 at the output end of the drive motor 31. The first rack 33 meshes with the side of the drive gear 32, and the second rack 34 meshes with the side of the drive gear 32 away from the first rack 33. The top surfaces of the two first racks 33 are connected to the bottom surface of the first clamp 4, and the upper surfaces of the two second racks 34 are connected to the bottom surface of the second clamp 12. By installing the drive motor 31, during operation, its output end drives the drive gear 32 to rotate, thereby driving the meshing first rack 33 and second rack 34 to move synchronously in opposite directions. The first clamp 4 and the second clamp 12 are driven to center and clamp the cylinder. A second electric push rod 13 is provided at the middle position of the rear surface of the second clamp 12. The output end of the second electric push rod 13 passes through the rear wall of the second clamp 12 and is connected to an auxiliary component. By setting the second electric push rod 13, its telescopic end can push the auxiliary component out of the interior of the second clamp 12 during operation, so as to fit with the cylinder. The auxiliary component includes a mounting box 141 and an auxiliary shaft 142. The telescopic end of the second electric push rod 13 is provided with a mounting box 141. Several equally spaced auxiliary shafts 142 are rotatably connected to the upper and lower sides of the inner surface of the mounting box 141. By setting the auxiliary shafts 142, when the cylinder is driven to move by the roller 6, the cylinder can drive the auxiliary shafts 142 to rotate, thereby assisting the cylinder to move.

[0026] Please see Figures 1-6 In this embodiment, support legs 15 are provided at the corners of the bottom surface of the workbench 1, and pads 16 are provided at the bottom of the support legs 15. By providing support legs 15 and pads 16, the overall stability of the device during use can be improved. Two symmetrical limiting grooves 17 are provided on the upper surface of the workbench 1. The first clamp 4 and the second clamp 12 are slidably connected to the limiting grooves 17 through limiting blocks. By providing limiting grooves 17, the movement direction of the first clamp 4 and the second clamp 12 can be restricted, thereby improving clamping accuracy and stability. Protective pads 18 are provided on the opposite surfaces of the first clamp 4 and the second clamp 12. The protective pads 18 are made of rubber. By providing protective pads 18, the outer surface of the cylinder can be protected to prevent scratching the cylinder after clamping.

[0027] During operation, the drive motor 31 drives the drive gear 32 to rotate, thereby causing the first rack 33 and the second rack 34 meshing with it to move synchronously in opposite directions. This causes the first clamp 4 and the second clamp 12 to center and clamp the cylinder. The second electric push rod 13 pushes the auxiliary component out of the second clamp 12 during operation, so that it fits against the cylinder. The auxiliary shaft 142 rotates when the cylinder moves under the influence of the roller 6, thus assisting the cylinder in moving. The support legs 15 and the pads 16 improve the overall stability of the device during use. The limiting groove 17 restricts the movement direction of the first clamp 4 and the second clamp 12, thereby improving clamping accuracy and stability. The protective pad 18 protects the outer surface of the cylinder, preventing scratches after clamping.

[0028] Through the above steps, by setting the first electric push rod 11, its telescopic end can push the mounting frame 5 towards one side of the processing cylinder during operation, so that the roller 6 fits against the cylinder. Then, the servo motor 9 is started, and its output end will drive the drive gear 10 to rotate during operation. The drive gear 10, in cooperation with the belt 8, will drive the driven gear 7 to rotate synchronously, thereby driving the roller 6 to rotate. The friction between the roller 6 and the surface of the cylinder allows the roller 6 to push the cylinder outward when rotating, thereby realizing automatic material discharge. This solves the problem that the existing cylinder clamping device for linear actuator processing only has a clamping function and lacks a material discharge function, which makes it impossible to push the processed cylinder parts out of the clamping surface, resulting in slow processing progress.
