Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a polishing device for the surface processing of a transmission shaft. Background Technology

[0002] As a key component in mechanical transmission systems, the surface quality of drive shafts directly affects the operating efficiency and service life of equipment. In various industrial sectors, particularly in automobile manufacturing, construction machinery, and precision instruments, stringent requirements are placed on the surface finish and dimensional accuracy of drive shafts.

[0003] According to CN219747291U, a transmission shaft polishing device with an oiling function is disclosed. This technology discloses a technical solution including "a base and an adjustment device, a worktable fixedly connected to the upper end of the base, a polisher body slidably connected to the side of the base close to the worktable, a connecting oil pipe penetrating the upper end of the polisher body, a driver provided at the upper end of the worktable, and the adjustment device including a support base, the support base fixedly connected to the upper end of the worktable, a limit frame fixedly connected to one end of the support base, and a support column fixedly connected to the end of the support base away from the limit frame. The user can then manually move one side of the transmission shaft to make the transmission shaft rotate between the three-jaw limit plate and the support head, so that the device can polish different surfaces of the transmission shaft, increasing the flexibility of the device in polishing the surface of the transmission shaft and improving the processing efficiency of the transmission shaft."

[0004] The above-mentioned solutions cannot flexibly adjust the relative angle between the polishing and the workpiece surface. When processing drive shafts with tapered or irregular contours, uneven polishing and unstable contact pressure often occur, making it difficult to meet the precision requirements for surface treatment quality. In particular, when dealing with workpieces of different geometries, it is necessary to frequently change special fixtures or polishing tools, which seriously restricts processing efficiency and quality consistency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drive shaft surface processing and polishing device. The device drives the workpiece to rotate through a drive mechanism, and the polishing mechanism uses a sanding belt for surface treatment. By adjusting the angle, pressure, and relative motion direction, efficient and uniform automated polishing processing can be achieved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drive shaft surface processing and polishing device, comprising a processing table, a polishing mechanism disposed on the processing table for processing the drive shaft, and a driving mechanism disposed on the processing table for driving the drive shaft, the polishing mechanism comprising:

[0007] The main components include a base frame fixed to the rear end of the top of the processing table, a shaft frame inside the base frame, a housing fixed to the right end of the shaft frame, a worm gear rotatably installed inside the housing, a right connector fixed to the right end of the worm gear, a worm rotatably installed inside the housing and meshing with the worm gear for transmission, a handwheel fixed to the outer end of the worm, and a left connector rotatably installed at the left end of the shaft frame via a rotating shaft.

[0008] The execution component is set on the main component and used for polishing the drive shaft.

[0009] Preferably, a first cylinder is installed on the top of both the left and right ends of the base frame, and the output end of the first cylinder at both ends is fixed to the left connector and the right connector, respectively.

[0010] Preferably, the actuating component includes drive wheels rotatably mounted on the left and right sides of the front end of the shaft frame, a vertical frame fixed to the rear end of the shaft frame, a slider longitudinally slidably mounted on the front end of the vertical frame, a tension wheel rotatably mounted on the front end of the slider, an abrasive belt installed between the tension wheel and the two drive wheels, and a knob screw rotatably mounted between the upper and lower ends of the vertical frame and threadedly installed with the slider.

[0011] Preferably, the execution component further includes a first motor mounted on the upper end of the shaft frame, a drive sprocket fixed at the output end of the first motor, a driven sprocket fixed at the rear end of the drive wheel, and a chain installed between the two driven sprockets and the drive sprocket.

[0012] Preferably, the driving mechanism includes a guide rail fixed to the front end of the top of the processing table, a slide block slidably mounted on the guide rail, a spindle rotatably mounted inside the slide block, a chuck fixed to the rear end of the spindle, and a second cylinder mounted at the front end of the guide rail for driving the slide block to move.

[0014] Beneficial effects

[0015] This invention provides a device for polishing the surface of a drive shaft. Compared with the prior art, it has the following advantages:

[0016] 1. By rotating the handwheel, the worm gear is driven to rotate, thereby driving the worm wheel and the right connecting head fixed to it to make precise angular displacement adjustments. At the same time, the left side of the shaft frame forms a hinged support through the left connecting head mounted on the rotating shaft, so that the entire execution component used for polishing can be angularly positioned around the left rotating shaft axis. The worm gear drive has a large transmission ratio and self-locking characteristics, which can achieve fine adjustment and maintain any angle lock, ensuring that the contact angle between the sand belt and the surface of the drive shaft is always in the optimal state during the polishing process, improving the adaptability to drive shafts with different tapers or irregular contours.

[0017] 2. When both first cylinders receive pneumatic signals simultaneously, their piston rods push or pull the left and right connectors with perfectly synchronized strokes, thereby driving the entire shaft frame and the polishing actuator mounted on it to make smooth linear motion in the vertical direction, enabling the sanding belt to be precisely aligned with the center position of drive shafts of different diameters; when the knob screw is rotated, the threaded drive converts the rotational motion into the linear motion of the slider, adjusting the wrap angle and tension of the sanding belt by changing the spatial position of the tension wheel; making it possible to quickly complete sanding belt replacement and tension calibration with just a knob operation.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a transmission shaft surface processing and polishing device, including a processing table 1, a polishing mechanism 2 disposed on the processing table 1 for processing the transmission shaft, and a driving mechanism 3 disposed on the processing table 1 for driving the transmission shaft. The polishing mechanism 2 includes:

[0027] The main component 21 includes a base frame 211 fixed to the rear end of the top of the processing table 1. A shaft frame 212 is provided inside the base frame 211. A housing 213 is fixed to the right end of the shaft frame 212. A worm gear 214 is rotatably installed inside the housing 213. A right connector 215 is fixed to the right end of the worm gear 214. A worm 216 is rotatably installed inside the housing 213 and meshes with the worm gear 214 for transmission. A handwheel 217 is fixed to the outer end of the worm 216. A left connector 219 is rotatably installed on the left end of the shaft frame 212 through a rotating shaft 218.

[0028] The execution component 22 is mounted on the main body component 21 and is used for polishing the drive shaft.

[0029] In this embodiment, the worm gear 216 is driven to rotate by rotating the handwheel 217, thereby driving the worm wheel 214 and the right connecting head 215 fixed thereto to perform precise angular displacement adjustment. At the same time, the left connecting head 219 installed on the left side of the shaft bracket 212 through the rotating shaft 218 forms a hinge support, so that the entire polishing execution component 22 can achieve angular positioning around the axis of the left rotating shaft 218. The worm wheel 214 and worm gear 216 transmission has a large transmission ratio and self-locking characteristics, which can achieve fine adjustment and maintain any angle lock, ensuring that the contact angle between the sand belt and the surface of the transmission shaft is always in the best state during the polishing process, and improving the adaptability to transmission shafts with different tapers or irregular contours.

[0030] Specifically, a first cylinder 2110 is installed on the top of both the left and right ends of the base frame 211, and the output ends of the first cylinder 2110 at both ends are fixed to the left connector 219 and the right connector 215 respectively.

[0031] In this embodiment, when the two first cylinders 2110 receive pneumatic signals at the same time, their piston rods will push or pull the left connector 215 and the right connector 219 with a completely synchronized stroke, thereby driving the entire shaft frame 212 and the polishing execution assembly 22 mounted on it to make a smooth linear motion in the vertical direction, so that the sanding belt 225 can be accurately aligned with the center position of the drive shaft of different diameters.

[0032] Specifically, the execution component 22 includes drive wheels 221 rotatably mounted on the left and right sides of the front end of the shaft frame 212, a vertical frame 222 fixed to the rear end of the shaft frame 212, a slider 223 longitudinally slidably mounted on the front end of the vertical frame 222, a tension wheel 224 rotatably mounted on the front end of the slider 223, a sanding belt 225 installed between the tension wheel 224 and the two drive wheels 221, and a knob screw 226 rotatably mounted between the upper and lower ends of the vertical frame 222 and threadedly mounted to the slider 223.

[0033] In this embodiment, when the knob screw 226 is rotated, the threaded transmission converts the rotational motion into the linear motion of the slider 223. The wrap angle and tension of the sanding belt 225 are adjusted by changing the spatial position of the tension wheel 224, so that the sanding belt replacement and tension calibration can be completed quickly with just a knob operation.

[0034] Specifically, the execution component 22 also includes a first motor 227 mounted on the upper end of the shaft frame 212. The output end of the first motor 227 is fixed with a drive sprocket 228, and the rear end of the drive wheel 221 is fixed with a driven sprocket 229. A chain 2210 is installed between the two driven sprockets 229 and the drive sprocket 228.

[0035] In this embodiment, when the first motor 227 starts, the power is evenly distributed to the two driven sprockets 229 through the transmission system consisting of the driving sprocket 228 and the chain 2210, ensuring that the two drive wheels 221 drive the sanding belt 225 to move at the same speed and phase; the symmetrical drive method makes the sanding belt 225 uniformly stressed, improving the stability and consistency of the polishing process.

[0036] Specifically, the drive mechanism 3 includes a guide rail 31 fixed to the front end of the top of the processing table 1, a slide block 32 slidably mounted on the guide rail 31, a spindle 33 rotatably mounted inside the slide block 32, a chuck 34 fixed to the rear end of the spindle 33, and a second cylinder 35 mounted at the front end of the guide rail 31 for driving the slide block 32 to move.

[0037] In this embodiment, when the second cylinder 35 is activated, it pushes the slide block 32 to slide smoothly on the guide rail 31, so that the drive shaft workpiece clamped on the chuck 34 can be precisely controlled in relative position with the polishing mechanism 2.

[0038] Specifically, the drive mechanism 3 also includes a driven pulley 36 fixed to the front end of the main shaft 33, a second motor 37 installed at the front end of the slide block 32, a drive pulley 38 fixed at the output end of the second motor 37, and a belt 39 installed between the drive pulley 38 and the driven pulley 36.

[0039] In this embodiment, when the second motor 37 starts, the power is smoothly transmitted to the main shaft 33 through the belt 39 transmission system, causing the workpiece on the transmission shaft clamped on the chuck 34 to rotate at a uniform speed; by setting the rotation direction of the workpiece on the transmission shaft to be opposite to the movement direction of the sand belt 225, a polishing mechanism of relative motion is formed.

[0040] The working principle and usage process of this utility model are as follows: First, the operator clamps the workpiece to be processed onto the chuck 34 of the drive mechanism 3 and secures it; the second motor 37 is started, driving the main shaft 33 to rotate via the belt 39, so that the workpiece rotates at a uniform speed; according to the workpiece diameter specifications, the two first cylinders 2110 are controlled to move synchronously, pushing the left connecting head 215 and the right connecting head 219 to drive the entire polishing mechanism 2 to rise and fall, so that the sanding belt 225 is aligned with the center position of the workpiece; the handwheel 217 is turned to drive the worm wheel 214 through the worm gear 216 to adjust the shaft bracket 21. 2. Angle 2 is used to make the sanding belt 225 form the optimal contact angle with the workpiece surface; the position of the tension wheel 224 is adjusted by rotating the knob screw 226 so that the sanding belt 225 obtains appropriate tension; the first motor 227 is started to drive the two drive wheels 221 synchronously through the chain 2210, which drives the sanding belt 225 to move at high speed, and its direction is opposite to the rotation direction of the workpiece; finally, the second cylinder 35 is controlled to push the slide 32 to slowly feed along the guide rail 31, so that the rotating workpiece is in full contact with the high-speed moving sanding belt 225, and the continuous and uniform polishing operation of the entire shaft is completed.
