Description

Technical Field

[0001] The invention relates to the technical field of universal joint assembly, and in particular to a universal joint assembly device for a drive shaft assembly. Background Art

[0002] The drive shaft assembly is mainly composed of an intermediate shaft and universal joints arranged at both ends of the intermediate shaft. The universal joint is generally called a constant velocity joint or a ball cage universal joint. The constant velocity joint is mainly composed of a spherical shell (outer raceway), a retaining cage (ball cage), a star sleeve (inner raceway) and a steel ball. When assembling the universal joint, the star sleeve is generally placed in the retaining cage first, and then the combined star sleeve and retaining cage are placed in the spherical shell. Finally, the steel ball is placed in the spherical shell by adjusting the angle of the star sleeve and the retaining cage. The installation of the steel ball is also the most difficult and tedious step in the entire universal joint assembly process.

[0003] At present, the installation of the bearing part in the ball cage universal joint is mainly achieved by manpower, especially the installation of the steel ball. Since the installation of the steel ball requires certain skills and the installation process is also cumbersome, it is necessary to constantly adjust the angle between the cage and the spherical shell (when the cage and the star sleeve are tilted at an angle of 45° in the spherical shell, the window hole on the cage will be exposed from the spherical shell, and the steel ball can be taken out and put in. When the universal joint is connected to the intermediate shaft on the drive shaft, due to the diameter limitation of the intermediate shaft, the intermediate shaft cannot drive the cage and the star sleeve to tilt at an angle of 45 degrees, and the intermediate shaft will be in advance against the edge of the spherical shell to cause restrictions. Therefore, when disassembling the universal joint, the intermediate shaft also needs to be removed from the universal joint), which makes the operation difficult and increases the workload of the staff. Therefore, it is necessary to propose a drive shaft assembly universal joint assembly device to realize the automatic installation of the steel ball. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a universal joint assembly device for a drive shaft assembly.

[0005] The present invention is implemented by the following technical scheme: a base platform, a transfer mechanism and an outer shell are arranged on the top of the base platform, and a steel ball installation mechanism is arranged in the outer shell; the transfer mechanism includes a rotating wheel rotatably arranged on the base platform for transferring the spherical shell of the universal joint, and the rotating wheel is provided with a plurality of positioning openings distributed in an annular shape, and the positioning openings are used to limit the spherical shell; the steel ball installation mechanism includes a funnel that can be lifted and rotated, a guide pipe is fixedly arranged at the bottom of the funnel, and a rocker that can swing back and forth is arranged on one side of the guide pipe, so as to adjust the angle of the universal joint retaining frame.

[0006] As a further improvement of the above solution, a first motor is provided at the bottom of the base platform, and the shaft of the rotating wheel is fixedly connected to the output shaft of the first motor.

[0007] As a further improvement of the above solution, a leakage opening is provided on one side of the base platform, and the leakage opening corresponds to the corresponding positioning opening, so that the universal joint can be transferred to the leakage opening driven by the rotating wheel and fall out after assembly.

[0008] As a further improvement of the above scheme, slides are fixedly installed on the inner walls on both sides of the shell, and the same shaft frame is slidably installed on the two slides for lifting and lowering. The funnel is rotatably connected to the shaft frame, and two hydraulic rods are fixedly installed on the top inner wall of the shell, and the output rods of the two hydraulic rods are fixedly connected to the shaft frame, thereby driving the entire steel ball installation mechanism to rise and fall stably.

[0009] As a further improvement of the above solution, a second motor for driving the steel ball installation mechanism to rotate is fixedly mounted on the shaft frame, and the second motor is transmission-connected to the funnel.

[0010] As a further improvement of the above scheme, a support frame is provided on the guide pipe, a reciprocating wheel disc is rotatably installed on the support frame, a third motor for driving the reciprocating wheel disc to rotate is fixedly provided on the support frame, a driving frame that can reciprocate with the reciprocating wheel disc is provided on the support frame, a push rod is fixedly installed on one side of the driving frame, one end of the push rod passes through the guide pipe and is hinged with a slider, and the slider is slidably connected to the rocker, thereby driving the rocker to swing back and forth.

[0011] As a further improvement of the above scheme, a push rod is limitedly installed in a sliding manner on the driving frame, and a push block extending into the guide pipe and used for pressing the steel ball is fixedly installed on one end of the push rod. A spring is sleeved on the push rod, and the two ends of the spring respectively press against the driving frame and the push block. A notch is provided on the push rod for the steel ball to pass through, so that when the driving frame moves, it can not only drive the rocker to swing through the push rod to adjust the angle between the retaining frame and the spherical shell, but also align the notch with the guide pipe so that the steel ball can automatically fall into the spherical shell, and also push the push rod and the push block to limit another steel ball to avoid too many steel balls falling in at one time.

[0012] As a further improvement of the above scheme, a pressing arm composed of a half gear and an arc rod is rotatably provided on one side of the guide pipe, and a rack that can transmit power to the half gear is provided at the bottom of the driving frame, so that when the driving frame drives the rack close to the pressing arm, the pressing arm can be withdrawn from the guide pipe, so that the steel ball can fall smoothly into the spherical shell. After the driving frame is reset, it will drive the pressing arm back into the guide pipe and press the steel ball that is easily stuck.

[0013] As a further improvement of the above scheme, the bottom end of the rocker is rotatably provided with a plug for inserting into the star sleeve, so that the rocker can smoothly adjust the angle of the star sleeve and the retaining frame, and also ensures that when the steel ball mounting mechanism is rotated to adjust the position, it will not drive the star sleeve, retaining frame and spherical shell to rotate together.

[0014] As a further improvement of the above scheme, two arc-shaped sliding openings are provided on both sides of the support frame, and a pair of sliding shafts are provided on both sides of the rocker. The four sliding shafts extend into the corresponding arc-shaped sliding openings respectively and are slidably connected with the corresponding arc-shaped sliding openings, so as to reasonably control the swing angle of the rocker.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The transfer mechanism composed of the first motor, the rotating wheel and other structures cooperates with the steel ball installation mechanism composed of the guide pipe and the rocker and other structures, which can automatically install the steel ball on the spherical shell with the retainer and the star sleeve installed. Compared with manual installation, it saves manpower and reduces the burden on the staff. In addition, during the process of installing the steel ball, the spherical shell, the retainer and the star sleeve can be assembled and arranged in advance, so as to improve the assembly efficiency of the universal joint. By allowing the push rod to pass through the guide pipe, and providing a notch on the push rod, and synchronously providing structures such as a stop rod, a spring, and a stop block on the driving frame, when installing the steel ball, the push rod can adjust the angle of the cage through the rocker, and at the same time, the notch and the guide pipe can allow the steel ball to be automatically discharged, so that the angle adjustment of the cage and the discharge of the steel ball can be achieved simultaneously, and the steel ball can be limited by the stop rod and the stop block at the same time, so that only one steel ball falls and completes the installation at a time, avoiding the disorderly falling of the steel balls affecting the normal installation; By arranging a pressing arm on the guide pipe and a rack at the bottom of the driving frame, after the steel ball is discharged from the guide pipe, the driving frame can first drive the pressing arm to press the steel ball when resetting, so that the steel ball can fall into the spherical shell smoothly, avoiding the steel ball getting stuck and causing installation failure.

A round opening is provided on the top of the shell 4. The top of the funnel 8 extends to the outside of the shell 4 through the round opening. The funnel 8 is used to store the steel balls. Slides 5 are fixedly installed on the inner walls of both sides of the shell 4. The same shaft frame 7 is installed on the two slides 5 for lifting and sliding. The funnel 8 is rotatably connected to the shaft frame 7. Two hydraulic rods 6 are fixedly installed on the top inner wall of the shell 4. The output rods of the two hydraulic rods 6 are fixedly connected to the shaft frame 7. A second motor 9 for driving the steel ball installation mechanism to rotate is fixedly installed on the shaft frame 7. The output shaft of the second motor 9 is Gears are provided on the funnel 8, and the two gears are meshed, so that the second motor 9 is connected to the funnel 8, thereby driving the entire steel ball installation mechanism to rise and fall stably. A guide pipe 11 is fixedly provided at the bottom of the funnel 8, and a rocker 17 that can swing back and forth is provided on one side of the guide pipe 11. A support frame 12 is provided on the guide pipe 11, and a reciprocating wheel 14 is rotatably installed on the support frame 12. A third motor 13 for driving the reciprocating wheel 14 to rotate is fixedly provided on the support frame 12, and a The driving frame 15 is provided with a slide groove 151 on one side of the driving frame 15. A guide shaft 141 extending into the slide groove 151 is fixedly installed on the reciprocating wheel 14, thereby driving the driving frame 15 to reciprocate. Two slide bars are fixedly installed in the support frame 12. Both slide bars penetrate the driving frame 15 and are slidably connected to the driving frame 15, thereby ensuring the stability of the driving frame 15. A push rod 16 is fixedly installed on one side of the driving frame 15. One end of the push rod 16 penetrates the guide pipe 11 and is hinged with a slider 161. The slider 161 is slidably connected to the rocker 17, thereby driving the rocker 17 to swing back and forth. , used to adjust the angle of the universal joint holder, the swing axis of the rocker 17 is the active axis point of the universal joint (the holder and the star-shaped sleeve are movable nodes in the spherical shell. When the holder and the star-shaped sleeve are tilted at an angle of 45° in the spherical shell, the window hole on the holder will be exposed from the spherical shell, and the steel ball can be taken out and put in at this time). Two arc-shaped sliding openings are provided on both sides of the support frame 12, and a pair of sliding shafts are provided on both sides of the rocker 17. The four sliding shafts extend into the corresponding arc-shaped sliding openings respectively and are slidably connected with the corresponding arc-shaped sliding openings, so as to reasonably control the swing angle of the rocker 17.

[0020] The above technical solution saves manpower and reduces the burden on workers compared to manual installation. Moreover, during the installation of the steel ball, the spherical shell, retaining frame and star sleeve can be assembled and arranged in advance, thereby improving the assembly efficiency of the universal joint.

[0021] A leak is provided on one side of the base platform 1, and the leak corresponds to the corresponding positioning hole 10, so that the universal joint can be transferred to the leak driven by the rotating wheel 3 after assembly and fall out.

[0022] A push rod 19 is limitedly installed on the driving frame 15 for sliding, and a push block 21 is fixedly installed on one end of the push rod 19 and extends into the guide pipe 11 for pressing the steel ball. A spring 20 is sleeved on the push rod 19, and the two ends of the spring 20 are respectively pressed against the driving frame 15 and the push block 21. A notch 22 for the steel ball to pass through is provided on the push rod 16, so that when the driving frame 15 moves, it can not only drive the rocker 17 to swing through the push rod 16 to adjust the angle between the retaining frame and the spherical shell, but also align the notch 22 with the guide pipe 11, so that the steel ball can automatically fall into the spherical shell, and also push the push rod 19 and the push block 21 to limit another steel ball to avoid too many steel balls falling at one time.

[0023] Through the above technical scheme, when installing the steel ball, the push rod 16 can adjust the angle of the retaining frame through the rocker 17, and at the same time, the notch 22 and the guide pipe 11 can automatically discharge the steel ball, so that the angle adjustment of the retaining frame and the discharge of the steel ball can be achieved simultaneously. In addition, the steel ball can be limited by the support rod 19 and the support block 21 at the same time, so that only one steel ball falls and completes the installation at a time, avoiding the disorderly falling of the steel balls affecting the normal installation.

[0024] A pressing arm 23 composed of a half gear and an arc rod is rotatably provided on one side of the guide pipe 11, and a rack 24 that can transmit power to the half gear is provided at the bottom of the driving frame 15, so that when the driving frame 15 drives the rack 24 close to the pressing arm 23, the pressing arm 23 can be withdrawn from the guide pipe 11, so that the steel ball can fall smoothly into the spherical shell. After the driving frame 15 is reset, it will drive the pressing arm 23 back into the guide pipe 11 and press the steel ball that is easily stuck.

[0025] Through the above technical solution, after the steel ball is discharged from the guide pipe 11, the driving frame 15 can first drive the pressing arm 23 to press the steel ball when resetting, so that the steel ball can fall into the spherical shell smoothly, avoiding the steel ball getting stuck and causing installation failure.

[0026] The bottom end of the rocker 17 is rotatably provided with a plug 18 for inserting into the star sleeve. The diameter of the plug 18 is close to the inner diameter of the internal spline on the star sleeve, so that the rocker 17 can smoothly adjust the angle of the star sleeve and the retaining frame. At the same time, when the steel ball mounting mechanism is rotated to adjust the position, it will not drive the star sleeve, the retaining frame and the spherical shell to rotate together.

[0027] The implementation principle of a universal joint assembly device for a drive shaft assembly in the embodiment of the present application is as follows: When assembling the ball cage universal joint, the steel ball to be installed is placed in the funnel 8 in advance, and then the spherical shell with the cage and the star sleeve installed is placed in the corresponding positioning hole 10 (in this process, the raceways on the spherical shell and the star sleeve need to be aligned with the window hole on the cage to facilitate the steel ball to fall in); Then the first motor 2 is started, the rotating wheel 3 drives the spherical shell to move to the bottom of the steel ball installation mechanism, and the hydraulic rod 6 is started to drive the steel ball installation mechanism to descend until the plug 18 is inserted into the inner spline in the middle of the star sleeve; The third motor 13 is started to drive the reciprocating wheel 14 to rotate, and the reciprocating wheel 14 drives the driving frame 15 to move and reset through the guide shaft 141. During the movement, the driving frame 15 drives the rocker 17 to swing with the retaining frame as the axis through the push rod 16, so that one side of the retaining frame is tilted and the window hole of the corresponding angle is exposed. During this process, the notch 22 on the push rod 16 will also guide the pipe 11 to align, so that the steel ball originally blocked by the push rod 16 will continue to fall through the notch 22, and fall into the spherical shell through the window hole on the retaining frame under the guidance of the guide pipe 11. At the same time, during the movement of the driving frame 15, the spring 20 will also push the push rod 19, so that the push rod 19 will resist the corresponding steel ball to prevent multiple steel balls from falling at the same time; When the pressing arm 23 is started, the pressing arm 23 will also rotate counterclockwise 90 degrees under the drive of the rack 24 to move out of the guide pipe 11, and when the driving frame 15 moves back to reset, the pressing arm 23 will rotate clockwise 90 degrees under the drive of the rack 24 to return to the guide pipe 11. If a steel ball is stuck at this time and cannot smoothly pass through the window hole on the retaining frame and fall into the spherical shell, the pressing arm 23 will press the steel ball to assist the steel ball to enter the spherical shell to complete the installation; When one steel ball is completed, the second motor 9 drives the steel ball installation mechanism to rotate with the rocker 17 and the plug 18 as the axis, so as to achieve azimuth adjustment and automatically install the next steel ball. This process is repeated until all steel balls are installed. The rotating wheel 3 transfers the assembled universal joint to the leak, so that the universal joint automatically falls out through the leak.

[0028] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
