Description

Technical Field

[0001] This invention relates to the field of universal joint manufacturing technology, specifically to a universal joint and drive shaft docking device for universal joint manufacturing. Background Technology

[0002] In the manufacturing process of universal joints, the mating and assembly of the cross joint (cross shaft) and the drive shaft (flange fork) is one of the key processes. As the core transmission component of the universal joint, the end of the cross joint must be precisely inserted into the flange hole at the end of the drive shaft. The alignment accuracy between the two directly affects the transmission smoothness, service life, and operational safety of the universal joint.

[0003] Existing automated docking equipment often only clamps a single component in the decant or drive shaft, lacking coordinated centering and angle adjustment capabilities between the two. Specifically, existing devices struggle to achieve radial synchronous centering and clamping of the decant during docking, and are also unable to make minute adjustments to the circumferential angle of the drive shaft, making it difficult for the decant shaft head to smoothly enter the flange hole of the drive shaft.

[0004] Therefore, developing a device that can achieve automated and high-precision docking between the 10-axis and the drive shaft has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a docking device for universal joints and drive shafts in universal joint production, solving the following technical problems: Existing automated docking equipment often only clamps a single component of the universal joint or drive shaft, lacking coordinated centering and angle adjustment functions between the two. Specifically, existing devices struggle to achieve radial synchronous centering and clamping of the universal joint during docking, and cannot make minute adjustments to the circumferential angle of the drive shaft, resulting in difficulty for the universal joint's shaft head to smoothly enter the flange hole of the drive shaft.

[0007] As a further aspect of the present invention: an annular toothed ring is provided on the outer surface of one end of the rotating disk, and a drive motor is provided on one side of the sliding seat; The output shaft of the drive motor is provided with a first driving gear that meshes with a ring gear.

[0008] As a further aspect of the present invention: one side of the rotating disk is fixedly provided with the same fixed disk by a plurality of second connecting rods; One end of the adjusting screw passes through the fixed disk and extends to the side away from the rotating disk, and a rotating handwheel is provided at this end.

[0009] As a further aspect of the present invention: a limiting post is provided on one side of the clamping seat and on the outer side of the rotating disk, the limiting post being used to abut against the outer wall of the ten-element.

[0010] As a further aspect of the present invention: the outer peripheral wall of the limiting post is provided with an arc-shaped surface that matches the outer side wall contour of the ten-element.

[0011] As a further aspect of the present invention: an annular groove is provided at the upper end of the centering seat, and limit grooves are provided on both sides of the annular groove; An arc-shaped plate is slidably engaged inside the limiting groove. A motor is installed at the lower end of the arc-shaped plate. The output shaft of the motor passes through the arc-shaped plate and extends to its upper end, where it is connected to a second drive gear. The upper end of the second drive gear is connected to the lower end of the T-shaped block. One side of the annular groove is provided with teeth arranged in an annular array to mesh with the second driving gear.

[0012] As a further embodiment of the present invention: a bidirectional lead screw is rotatably provided at the upper end of the T-block; The outer surface of the bidirectional lead screw is symmetrically threaded with clamping blocks, and the opposite surface of the clamping blocks is provided with an arc-shaped groove that matches the outer surface of the drive shaft.

[0013] As a further embodiment of the present invention: a clamping component is provided in the middle of the upper end of the base; The clamping assembly includes a U-shaped frame fixedly mounted on the upper end of the base, a lifting cylinder is provided at the upper end of the U-shaped frame, and the output shaft of the lifting cylinder extends to the lower end of the U-shaped frame and is provided with a horizontal plate. The lower end of the U-shaped frame is symmetrically fixed with an L-shaped plate. The horizontal section of the L-shaped plate is symmetrically provided with guide slots. A clamping plate is slidably engaged in the guide slot. Both ends of the horizontal plate are rotatably provided with a third connecting rod. The end of the third connecting rod away from the horizontal plate is rotatably connected to the clamping plate.

[0014] As a further aspect of the present invention: a clamping post is provided at the lower end of the clamping plate and on the side facing the 10-byte.

[0015] As a further aspect of the present invention: an elastic buffer pad is provided at the end of the clamping column facing the ten-byte side.

[0016] The beneficial effects of this invention are: (1) The present invention provides an adjustable clamping component. Multiple sliding grooves are arranged in a ring array on one side of the rotating disk. Clamping seats are slidably engaged in the sliding grooves. The clamping seats are connected to the same sliding disk via the first connecting rod. When the adjusting screw in the middle of the sliding disk rotates, it can drive all clamping seats to move synchronously in the radial direction, thereby driving the limiting post to move synchronously from all sides to the center or to open outward. The arc-shaped surface of the outer side of the limiting post fits with the inner wall contour of the ten-element, realizing radial synchronous centering clamping of the ten-element. This effectively solves the problems of difficult centering and uneven clamping force of the ten-element in the prior art, and significantly improves the positioning accuracy and clamping stability of the ten-element. (2) By setting up a rotating docking assembly, the upper end of the center seat is provided with an annular groove, and an arc plate is slidably engaged in the annular groove. The motor at the lower end of the arc plate drives the second drive gear to rotate. The second drive gear meshes with the teeth on one side of the annular groove, which can drive the T-block to make a circumferential motion along the annular groove, so that the drive shaft clamped at the upper end of the T-block can make a circumferential angle adjustment relative to the cross-shaped part, which facilitates the cross-shaped part shaft head to smoothly enter the flange hole of the drive shaft. At the same time, the drive motor drives the rotating disk to rotate to realize the angle adjustment of the cross-shaped part. The two work together to realize the bidirectional angle alignment between the cross-shaped part and the drive shaft, effectively solving the technical problem that the shaft head is difficult to enter the hole due to angle deviation during the docking process.

[0017] (3) By setting up a clamping assembly, the lifting cylinder at the upper end of the U-shaped frame pushes the horizontal plate to move up and down. The horizontal plate drives the clamping plate to slide laterally along the guide groove in the horizontal direction of the L-shaped plate via the third connecting rod, so that the clamping column at the lower end of the clamping plate moves relative to each other from both sides, and clamps the opposite two shaft ends of the cross-shaped element from both ends. The end of the clamping column is provided with an elastic buffer pad, which can stably clamp the cross-shaped element after the docking is completed, preventing displacement or loosening in subsequent riveting or welding processes, and further ensuring the consistency and reliability of the assembly.

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] In universal joint production, the mating assembly of the universal joint and the drive shaft is a critical process, and its alignment accuracy directly affects the smoothness of transmission and service life. Existing automated mating equipment mostly focuses on clamping single components and lacks radial synchronous centering of the universal joint and fine-tuning of the drive shaft's circumferential angle, making it difficult for the universal joint head to smoothly enter the flange hole. Therefore, there is an urgent need to develop a device that can achieve coordinated centering and high-precision mating of both components.

[0025] Example 1: Please refer to Figure 1 , Figure 2 As shown, a universal joint and drive shaft docking device for universal joint production includes a base 100. A sliding seat 101 is slidably disposed on the upper end of the base 100. The reciprocating sliding method of the sliding seat 101 can be selected by cylinder drive or by servo motor, lead screw and slider. When the cylinder is started, the cylinder is disposed on the upper top surface of the base 100, and the piston rod end of the cylinder is connected to the sliding seat 101. If the servo motor, lead screw and slider drive is used, a sliding groove is opened on the upper end of the base 100. The lead screw is rotatably disposed in the sliding groove on the upper end of the base 100. The servo motor drives the lead screw, and the lead screw drives the slider to reciprocate within the sliding groove. The slider drives the sliding seat 101 to reciprocate. An adjustable clamping assembly 200 is rotatably mounted on the sliding base 101. The adjustable clamping assembly 200 is used to stably clamp the ten-element object. The adjustable clamping assembly 200 includes a rotating disk 201 that is rotatably engaged on the sliding base 101. The sliding base 101 has an annular engaging groove that runs through both sides of it. The rotating disk 201 is movably engaged on the sliding base 101.

[0026] A ring gear 202 is provided on the outer surface of one end of the rotating disk 201, and a drive motor 203 is provided on one side of the sliding seat 101. A first drive gear 204 that meshes with the ring gear 202 is provided on the output shaft of the drive motor 203.

[0027] For further details, please refer to Figure 2 , Figure 3As shown, a plurality of sliding grooves 205 are arranged in a ring array on one side of the rotating disk 201. Each of the sliding grooves 205 has a clamping seat 206 slidably engaged. A limiting post 207 is provided on one side of the clamping seat 206 and on the outer side of the rotating disk 201. The outer surface of the limiting post 207 is set as an arc-shaped surface that matches the contour of the outer wall of the cross-shaped object. The arc-shaped surface is used to form a stable surface contact with the cross-shaped object during clamping, thereby achieving centering and stable clamping of the cross-shaped object.

[0028] For further details, please refer to Figure 4 As shown, a first connecting rod 208 is rotatably arranged on the other side of the clamping seat 206 and in the inner cavity of the rotating disk 201. The same sliding disk 209 is rotatably arranged on the side of the multiple first connecting rods 208 away from the clamping seat 206. An adjusting screw 210 is threadedly connected to the middle of the sliding disk 209. One end of the adjusting screw 210 is rotatably connected to the rotating disk 201. The same fixed disk 212 is fixedly arranged on one side of the rotating disk 201 through multiple second connecting rods 211. The other end of the adjusting screw 210 passes through the fixed disk 212 and extends to the other side and is provided with a rotating handwheel. If a motor drive is used, one end of the adjusting screw 210 can also be connected to a motor.

[0029] In use, the operator rotates the handwheel forward or starts the motor connected to the adjusting screw 210, causing the adjusting screw 210 to rotate. This drives the sliding plate 209 to move closer to the rotating plate 201. Multiple first connecting rods 208 push the clamping seat 206 to move radially outward along the slide groove 205 synchronously, causing multiple limiting posts 207 to open outward, placing the cross-shaped element on one side of the rotating plate 201. Then, the operator rotates the handwheel or motor in the opposite direction, causing the sliding plate 209 to move away from the rotating plate 201. The first connecting rods 208 pull the clamping seat 206 radially inward synchronously, causing the limiting posts 207 to move from four... When the circumferential center closes, the arc-shaped contact surface of the outer side of the limiting post 207 fits against the contour of the inner wall of the ten-element, thereby tightening the ten-element and achieving centering and stable clamping of the ten-element; when it is necessary to adjust the circumferential angle of the ten-element to align with the drive shaft, the drive motor 203 is started, and through the meshing transmission of the first drive gear 204 and the ring gear 202, the rotating disk 201 is driven to rotate inside the sliding seat 101, and the clamped ten-element rotates synchronously with the rotating disk 201 to the required angle; finally, the reciprocating sliding drive mechanism of the sliding seat 101 is started, so that the sliding seat 101 moves towards the drive shaft, completing the docking of the ten-element with the drive shaft.

[0030] For further details, please refer to Figure 5 , Figure 6As shown, a rotating docking assembly 300 is slidably mounted on the upper end of the base 100. The reciprocating sliding method of the rotating docking assembly 300 can be selected as cylinder drive or motor, lead screw and slider drive. The rotating docking assembly 300 includes a centering seat 301 slidably mounted on the upper end of the base 100. An annular groove 302 is opened at the upper end of the centering seat 301. Limiting grooves 303 are opened on both side walls of the annular groove 302. An arc-shaped plate 304 is slidably engaged inside the limiting groove 303. A motor is installed at the lower end of the arc-shaped plate 304. The output shaft passes through the arc-shaped plate 304 and extends to its upper end, where it is connected to a second drive gear 305. A ring array of teeth 310 meshing with the second drive gear 305 is arranged on one side of the annular groove 302. A T-block 306 is located at the upper end of the second drive gear 305. A sliding groove is laterally formed at the upper end of the T-block 306, and a bidirectional lead screw 307 is rotatably mounted within the sliding groove. One end of the bidirectional lead screw 307 extends to the outside of the T-block 306 and is connected to a motor. An arc-shaped positioning groove 308 is longitudinally formed at the upper end of the T-block 306. A clamping block 309 is symmetrically threaded onto the outer surface of the bidirectional lead screw 307. An arc-shaped groove adapted to the outer surface of the drive shaft is formed on the opposite side of the clamping block 309.

[0031] First, the drive shaft is placed in the arc-shaped positioning groove 308 at the upper end of the T-block 306. The motor at the upper end of the T-block 306 is started to drive the bidirectional lead screw 307 to rotate, driving the two clamping blocks 309 to move towards each other along the sliding groove, so that the arc-shaped grooves on the opposite sides of the clamping blocks 309 clamp the outer surface of the drive shaft from both sides, achieving stable clamping of the drive shaft. Then, the centering seat 301 slides forward at the upper end of the base 100 via a cylinder or motor lead screw, driving the drive shaft closer to the tenth element. When it approaches the tenth element, the motor at the lower end of the arc plate 304 is started to drive the second drive gear 305 to rotate. The driven gear 305 meshes with the teeth 310, and the second driving gear 305 drives the T-block 306 to make a circular motion along the annular groove 302, so that the drive shaft rotates at a small offset angle relative to the cross-shaped part, so that the shaft end of the cross-shaped part can smoothly enter the flange hole of the drive shaft. After the initial fitting is completed, the motor at the lower end of the arc plate 304 is started again, and the second driving gear 305 drives the T-block 306 to rotate in the opposite direction, so that the drive shaft returns to the vertical centering position, achieving precise alignment between the cross-shaped part and the drive shaft. Finally, with the further sliding of the sliding seat 101, the docking of the cross-shaped part and the drive shaft is completed.

[0032] Example 2: Based on Example 1, please refer to... Figure 7As shown, a clamping assembly 400 is provided in the middle of the upper end of the base 100. The clamping assembly 400 includes a U-shaped frame 401 fixedly mounted on the upper end of the base 100. A lifting cylinder 402 is provided at the upper end of the U-shaped frame 401. The output shaft of the lifting cylinder 402 extends to the lower end of the U-shaped frame 401 and is provided with a horizontal plate 403. L-shaped plates 404 are symmetrically fixed on both sides of the lower end of the U-shaped frame 401. Guide slots are opened on the multiple L-shaped plates 404 in the vertical and horizontal directions, respectively. The two ends of the horizontal plate 403 are slidably engaged in the vertical slots of the L-shaped plates 404 on both sides, and clamping plates 405 are slidably engaged in the horizontal slots of the L-shaped plates 404.

[0033] Both ends of the horizontal plate 403 are rotatably equipped with third connecting rods 406, and the ends of the multiple third connecting rods 406 away from the horizontal plate 403 are rotatably connected to the corresponding clamping plates 405. Each clamping plate 405 has a clamping post 407 on its lower end near the cross-shaped element. The clamping posts 407 on both sides are arranged opposite each other to clamp the opposite two shaft ends of the cross-shaped element from both ends when the clamping assembly 400 is activated. An elastic buffer pad is provided at the end of the clamping post 407 facing the cross-shaped element.

[0034] After the cross-shaped element and the drive shaft are docked in cooperation with the adjustable clamping assembly 200 and the rotating docking assembly 300, the lifting cylinder 402 at the upper end of the U-shaped frame 401 is activated, and its output shaft extends vertically downward, pushing the horizontal plate 403 to slide downward along the vertical slots of the L-shaped plates 404 on both sides. When the horizontal plate 403 moves downward, it drives the third connecting rod 406 rotatably connected at both ends to move. The third connecting rod 406 converts the vertical movement of the horizontal plate 403 into the lateral sliding of the clamping plate 405 along the horizontal slots of the L-shaped plate 404, pushing the clamping plates 405 on both sides to move inward (i.e. towards the cross-shaped element) synchronously. As the clamping plates 405 move towards each other, the pressing column 407 fixed at its lower end approaches from both sides of the cross-shaped element, and finally presses the opposite shaft ends of the cross-shaped element from both ends, realizing stable pressing of the cross-shaped element, preventing displacement or loosening after docking, and facilitating subsequent riveting or welding processes.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
