Description

Technical Field

[0001] The invention relates to the technical field of automobile parts assembly, in particular to an automobile drive shaft assembly assembly device. Background Art

[0002] The automobile drive shaft assembly is an important component of the automobile. One end of the automobile drive shaft is connected to the universal joint at the power output end of the automobile gearbox, and the other end is connected to the universal joint at the power input part of the automobile wheel. Its main function is to transmit torque between the automobile gearbox and the wheel. The assembly steps of the automobile drive shaft assembly are generally divided into: installing the dust cover and damping block on the real shaft, pressing the tripod and upper retaining ring, pressing the fixed section, greasing the dust cover of the fixed section and locking the clamp, greasing the dust cover of the mobile end and locking the clamp, weighing and appearance inspection, oiling and packing, and each step requires specific equipment for auxiliary assembly.

[0003] When the fixed section is pressed, it is assisted by a fixed section press machine. The fixed section press machine is mainly composed of a fixed section positioning table, a limiting frame and a press machine. When the fixed section of the drive shaft assembly is pressed, the fixed section needs to be placed on the positioning table first, and then the limiting frame limits the fixed section, and then the real shaft is placed on the limiting frame, and finally the press machine presses the real shaft. At present, when the staff operates the press machine to press the drive shaft and the fixed section, the rotation of the real shaft and the fixed section is purely manual, and must be carried out according to the steps of placing the fixed section first-clamping the fixed section with the limiting frame-placing the real shaft. The entire press work cannot pre-install the fixed section and the real shaft, which wastes the idle time of the fixed section press, not only affecting the efficiency of the drive shaft assembly, but also causing the situation that the machine stops when people stop, making it difficult for the staff to split their time. Therefore, it is necessary to propose an automobile drive shaft assembly assembly equipment to solve the above problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides an automobile drive shaft assembly assembly device.

[0005] The present invention is implemented by the following technical scheme: a real shaft press machine, a pre-installation rotation mechanism is arranged in front of the real shaft press machine, the pre-installation rotation mechanism comprises a bottom box, a rotating frame which can rotate automatically is arranged on the bottom box, and a plurality of pre-installation frames which are distributed in an annular shape and can be telescopic are arranged on the rotating frame, so that the fixed section and the real shaft can be placed on the pre-installation frame in advance, and when the real shaft and the fixed section are transferred to the press position, the real shaft and the fixed section are automatically pushed into the real shaft press machine for press installation; The pre-installed frame includes a main frame and a sub-frame which is slidably mounted on the main frame and can be raised and lowered and reset. The sub-frame is provided with a fixed section limiting bucket and a real shaft limiting sleeve equipped with a magnet, so that the pre-installed real shaft and fixed section can be limited, and it can also adapt to the pressing work of the real shaft pressing machine.

[0006] As a further improvement of the above scheme, a plurality of sliding blocks that can slide in a circular trajectory are arranged in the bottom box, one side of the sliding block extends outside the bottom box and is fixedly connected to the main frame of the pre-installed frame, and a first hydraulic rod is fixedly installed in the bottom box, and a buckle that is engaged with the sliding block is arranged on the output rod of the first hydraulic rod, so that each pre-installed frame is engaged with the buckle when it moves to the buckle, and the first hydraulic rod can push and pull the pre-installed frame and the fixed section and real shaft placed on the pre-installed frame through the buckle, thereby completing the work of putting on and taking out the pre-installed real shaft and the fixed section.

[0007] As a further improvement of the above scheme, the bottom of the buckle extends outside the bottom box and is fixedly installed with a second hydraulic rod. The bottom of the sub-frame is L-shaped and corresponds to the output rod of the second hydraulic rod, so that the lowering and placement of the real shaft and the fixed section can be completed without affecting the normal extension and retraction of the pre-installed frame.

[0008] As a further improvement of the above solution, a retractable first extension strip is arranged in the bottom box, and one end of the first extension strip is connected to the buckle and the second hydraulic rod, thereby improving the stability of the second hydraulic rod without affecting the normal extension and retraction of the second hydraulic rod.

[0009] As a further improvement of the above scheme, an annular slide rail is arranged in the bottom box, and a pulley is arranged at the bottom of the slider, and the pulley extends into the annular slide rail and is slidably connected with the annular slide rail, so that when the rotating frame drives multiple pre-installed frames to rotate, the pre-installed frames can stably maintain the current state and will not be extended prematurely due to inertia.

[0010] As a further improvement of the above scheme, a reverse thrust mechanism is arranged on the pre-installed frame, and the reverse thrust mechanism includes two support blocks arranged on the main frame, positioning rods are arranged on the two support blocks, a sliding sleeve on the positioning rod is provided with a first spring and a connecting block, and a long sliding hole is arranged on the main frame, one side of the connecting block passes through the long sliding hole and is fixedly connected to the sub-frame, so that the sub-frame can automatically rise and reset under the push of the first spring after descending.

[0011] As a further improvement of the above scheme, an articulated frame is provided on the sub-frame, and the fixed-section limiting bucket is rotatably connected to the articulated frame, and the center of gravity of the fixed-section limiting bucket is located at the bottom, so that after the fixed-section press-fitting of the drive shaft assembly is completed, it is only necessary to separate the drive shaft assembly from the magnet on the real shaft limiting sleeve, and the drive shaft assembly can be reversed and fall off by itself, and when the drive shaft assembly falls off, the fixed-section limiting bucket can reset itself.

[0012] As a further improvement of the above scheme, a cam ring is arranged above the rotating frame, and a reset ejection mechanism is arranged on the real shaft limiting sleeve, and the reset ejection mechanism includes a sleeve arranged on the real shaft limiting sleeve, and a push rod is slidably installed in the sleeve, one end of the push rod is in contact with the cam ring, and two abutment blocks are arranged on the push rod, both of which extend outside the sleeve and are slidably connected to the sleeve, and a second spring abutting against the two abutment blocks is sleeved on the sleeve, so that when the push rod follows the pre-installed frame to transfer to the protruding position of the cam ring, it will squeeze the second spring and eject the real shaft adsorbed by the magnet from the real shaft limiting sleeve, so that the drive shaft assembly that loses the adsorption of the magnet completes the reversal and detaches from the pre-installed frame.

[0013] As a further improvement of the above solution, a roller is provided at one end of the push rod, and the roller is in contact with the cam ring, thereby reducing the wear between the push rod and the cam ring and making the transfer of the push rod smoother.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By adding a pre-installation rotation mechanism to the real shaft press machine, when the real shaft and the fixed joint are press-fitted, the real shaft and the fixed joint to be press-fitted can be pre-installed in batches, so that when the real shaft press machine is press-fitting the current real shaft and the fixed joint, the subsequent real shaft fixed joint pre-installation work can be carried out simultaneously, so that the idle time can be utilized to improve the assembly efficiency of the drive shaft assembly, and by realizing the pre-installation of the real shaft and the fixed joint, after completing all the pre-installation work, the staff can spare extra free time without delaying the press-fitting work, so as to avoid the staff affecting the press-fitting work of the real shaft and the fixed joint due to handling other things; The pre-installation frame composed of a main frame, a sub-frame, a sliding block, a fixed-section limiting bucket and other structures, in conjunction with the first hydraulic rod, the second hydraulic rod and the buckle and other structures, can not only realize the pre-installation and limitation of the real shaft and the fixed section, but also can smoothly send the real shaft and the fixed section into the real shaft press for pressing. At the same time, its structural design can also smoothly cooperate with the pressing and rotation work of the real shaft press. Moreover, a set of pushing and pressing structures can be used to realize the pushing and pressing operations of multiple pre-installation frames. Compared with setting a set of pushing and pressing mechanisms for each pre-installation frame, its structure is simpler and easier to maintain later.

[0015] The reset ejection mechanism composed of a sleeve, a push rod, a second spring and other structures, together with the cam ring, constitutes an automatic ejection mechanism of the pre-installed frame, which can eject the pressed drive shaft assembly from the real shaft limiting sleeve, so that it is separated from the magnet. Subsequently, the drive shaft assembly that has lost the magnet adsorption will reverse with the fixed section limiting bucket as the axis, and automatically fall off from the fixed section limiting bucket after reversing, thereby completing the automatic falling off work after pressing, eliminating the tedious need for staff to manually remove it.

Two second extension bars 10 are arranged on the main frame 11, and the two second extension bars 10 both extend into the sliding sleeve on the rotating frame 4. A fixed section limiting bucket 15 and a real shaft limiting sleeve 16 equipped with a magnet 17 are arranged on the sub-frame 12, so that the pre-installed real shaft and the fixed section can be limited, and it can also adapt to the pressing work of the real shaft pressing machine 1. A reverse thrust mechanism is arranged on the pre-installed frame, and the reverse thrust mechanism includes two support blocks arranged on the main frame 11, positioning rods are arranged on the two support blocks, and the sliding sleeve on the positioning rod is provided with a first spring and a connecting block. A long sliding hole is arranged on the main frame 11, and one side of the connecting block passes through the long sliding hole and is fixedly connected to the sub-frame 12, so that the sub-frame 12 can automatically rise and reset under the push of the first spring after it is lowered.

[0020] Through the above technical scheme, when the real shaft and the fixed joint are press-fitted, the real shaft and the fixed joint to be press-fitted can be pre-installed in batches, so that the real shaft press-fitting machine 1 can simultaneously perform the subsequent real shaft fixed joint pre-installation work when the current real shaft and the fixed joint are press-fitted, thereby making use of the idle time to improve the assembly efficiency of the drive shaft assembly, and by realizing the pre-installation of the real shaft and the fixed joint, after completing all the pre-installation work, the staff can have extra free time without delaying the pressing work, thereby avoiding the staff from affecting the pressing work of the real shaft and the fixed joint due to handling other things.

[0021] A plurality of sliders 13 that can slide in an annular track are arranged in the bottom box 2. One side of the slider 13 extends outside the bottom box 2 and is fixedly connected to the main frame 11 of the pre-installed frame. A notch 9 for the slider 13 to rotate and move is arranged on the side of the bottom box 2, so that the slider 13 can rotate with the pre-rotating frame and the rotating frame 4 without being restricted by the bottom box 2. An annular slide rail 14 is arranged in the bottom box 2. A pulley is arranged at the bottom of the slider 13. The pulley extends into the annular slide rail 14 and is slidably connected to the annular slide rail 14, so that the rotating frame 4 can rotate in the When driving multiple pre-installed racks to rotate, the pre-installed racks can stably maintain the current state and will not be extended prematurely due to inertia. A first hydraulic rod 5 is fixedly installed in the bottom box 2, and a buckle 6 engaged with the slider 13 is arranged on the output rod of the first hydraulic rod 5, so that each pre-installed rack is engaged with the buckle 6 when it moves to the buckle 6.

The bottom of the sub-frame 12 is L-shaped and corresponds to the output rod of the second hydraulic rod 8, so that the lowering and placement of the real shaft and the fixed section can be completed without affecting the normal extension and retraction of the pre-installed frame. A retractable first extension bar 7 is provided in the bottom box 2, and one end of the first extension bar 7 is connected to the buckle 6 and the second hydraulic rod 8, so that the stability of the second hydraulic rod 8 can be improved without affecting the normal extension and retraction of the second hydraulic rod 8.

[0022] Through the above technical scheme, the real shaft and the fixed section can be smoothly sent into the real shaft press assembling machine 1 for press assembling. At the same time, its structural design can also smoothly cooperate with the pressing and rotating work of the real shaft press assembling machine 1. Moreover, a set of pushing and pressing structures can be used to realize the pushing and pressing operations of multiple pre-assembly frames. Compared with setting a set of pushing and pressing mechanisms for each pre-assembly frame, its structure is simpler and easier to maintain later.

[0023] An articulated frame is provided on the sub-frame 12, and the fixed section limiting bucket 15 is rotatably connected to the articulated frame. The center of gravity of the fixed section limiting bucket 15 is located at the bottom, so that after the fixed section is pressed, the drive shaft assembly only needs to separate the drive shaft assembly from the magnet 17 on the real shaft limiting sleeve 16, and the drive shaft assembly can be reversed and fall off by itself. When the drive shaft assembly falls off, the fixed section limiting bucket 15 can reset itself. A cam ring 18 is provided above the rotating frame 4, and the cam ring 18 is fixedly connected to the top connecting frame 24. A reset ejection mechanism is provided on the real shaft limiting sleeve 16, and the reset ejection mechanism includes a sleeve 19 provided on the real shaft limiting sleeve 16, and a push rod 20 is slidably installed in the sleeve 19, and one end of the push rod 20 is connected to the The cam ring 18 is in contact with each other, and two abutments 21 are arranged on the push rod 20. The two abutments 21 extend outside the sleeve 19 and are slidably connected with the sleeve 19. A second spring 22 is sleeved on the sleeve 19 and abuts against the two abutments 21. In this way, when the push rod 20 follows the pre-installed frame to move to the protruding position of the cam ring 18, it will squeeze the second spring 22 and push the real shaft adsorbed by the magnet 17 out of the real shaft limiting sleeve 16, so that the driving shaft assembly that loses the adsorption of the magnet 17 completes the reversal and detaches from the pre-installed frame. A roller 23 is arranged at one end of the push rod 20, and the roller 23 is in contact with the cam ring 18, so as to reduce the wear between the push rod 20 and the cam ring 18 and make the transfer of the push rod 20 smoother.

[0024] Through the above technical solution, the pressed-in drive shaft assembly can be pushed out from the real shaft limiting sleeve 16, so that it is separated from the magnet 17. Subsequently, the drive shaft assembly that has lost the adsorption of the magnet 17 will reverse with the fixed section limiting bucket 15 as the axis, and automatically fall off from the fixed section limiting bucket 15 after the reversal, thereby completing the automatic falling off work after pressing, eliminating the tedious manual removal by the staff.

[0025] The implementation principle of an automobile drive shaft assembly assembly device in the embodiment of the present application is: When in use, first place the fixed section into the corresponding fixed section limiting bucket 15, then place the real shaft into the corresponding real shaft limiting sleeve 16, and let the bottom end of the real shaft contact the fixed section, and repeat this process until all the fixed sections and real shafts are pre-placed on multiple pre-installed racks; The motor 3 is started, and the motor 3 drives the multiple pre-installed frames and the real shafts and fixed sections placed on the pre-installed frames to rotate through the rotating frame 4. When the pre-installed frame with the fixed section and the real shaft drives the slider 13 thereon to transfer to the buckle 6, the first hydraulic rod 5 is started, and the first hydraulic rod 5 pushes the pre-installed frame through the buckle 6, so that the pre-installed frame drives the fixed section and the real shaft to be pressed into the pressing position of the real shaft pressing machine 1. In this process, the second hydraulic rod 8 also moves synchronously with the buckle 6, and then the second hydraulic rod 8 presses the sub-frame 12 of the pre-installed frame. Press down, the sub-frame 12 drives the real shaft and fixed section to be pressed down, so that the bottom end of the fixed section falls into the positioning hole of the positioning table of the real shaft press machine 1, and then the limiting frame clamps and limits the fixed section and the real shaft. Finally, the real shaft and the fixed section are pressed by the press machine, and in this process, the real shaft and the fixed section are rotated to a certain extent so that the two can be smoothly connected, and the fixed section limiting bucket 15 and the real shaft limiting sleeve 16 will not limit the press, so that the real shaft and the fixed section can smoothly complete the pressing and rotating operations; When the real shaft and the fixed section are pressed and installed, the first hydraulic rod 5 pulls back the pre-installed frame and the pressed and installed drive shaft assembly through the buckle 6, and when the slider 13 returns to the annular slide rail 14, the pre-installed frame can continue to rotate with the rotating frame 4, and when the reset ejection mechanism on the real shaft limiting sleeve 16 moves to the raised position of the cam ring 18, it is ejected and the drive shaft assembly adsorbed on the real shaft limiting sleeve 16 by the magnet 17 is pushed open, and after the drive shaft assembly loses the adsorption of the magnet 17, it will be reversed with the fixed section limiting bucket 15 as the axis due to the influence of the center of gravity, and then detached from the pre-installed frame, and then the fixed section limiting bucket 15 resets itself, and at the same time, in order to prevent the pressed drive shaft assembly from falling and being damaged after detaching from the pre-installed frame, an elastic receiving object (such as a material guide inclined plate with a sponge pad) needs to be provided below for receiving.

[0026] 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.
