Description

Technical Field

[0001] This invention relates to the field of automotive component assembly equipment technology, and in particular to a fully automatic assembly equipment for a short-handled movable joint guard ring and locking screw. Background Technology

[0002] In the automotive production line, the drive shaft is an important component that connects to the engine. It is crucial in terms of both production volume and quality requirements. The drive shaft is connected to the gearbox by a short-handled sliding joint. In the production process of the short-handled sliding joint, the press-fitting of the retaining ring and the assembly of the locking screw are usually set up by two single stations. This not only consumes manpower but also cannot guarantee continuous supply to the production line.

[0003] In summary, providing an automated assembly equipment that saves labor costs and improves production line productivity is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic assembly equipment for the retaining ring and locking wire of the short-handle moving joint, which solves the technical problem that the existing short-handle moving joint retaining ring pressing and locking wire assembly processes require two single-station assembly machines, which consume manpower and cannot guarantee continuous supply to the production line.

[0005] To achieve the above objectives, the present invention provides a fully automatic assembly equipment for a short-handled movable joint retainer and a locking wire, comprising:

[0006] The support frame has a chain conveyor system on its bearing surface for conveying short handles. The short handles are connected to a lifting and transfer system, which clamps the short handles.

[0008] The clamping mechanism includes an inverted L-shaped support frame. The vertical part of the support frame is connected to a clamping plate via a fourth guide rail. The horizontal part of the support frame is equipped with a clamping cylinder. The output end of the clamping cylinder is connected to the clamping plate. The end of the clamping plate near the bearing surface is equipped with a pressure rod. The clamping cylinder is used to push the clamping plate so that the pressure rod can hold and fix the short handle.

[0009] The pushing mechanism includes a pushing bracket, on which a linear servo motor is mounted. A pushing loading plate is connected to the linear servo motor. The pushing loading plate is parallel to the bearing surface and can slide perpendicular to the bearing surface. A pushing cylinder is connected to the pushing loading plate.

[0014] The pressing mechanism includes a pressing ring carrier plate with a pressing ring cylinder mounted vertically. The pressing ring carrier plate is positioned above the cutting ring carrier plate via a vertical rod. The output end of the pressing ring cylinder passes through the pressing ring carrier plate and is connected to a pressing head. The cutting ring cylinder is used to push the protective ring pusher plate so that it corresponds to the end of the pressing head. The pushing ring cylinder holds the protective ring pusher plate, so that the protective ring is fitted onto the outside of the pressing head. The pressing ring cylinder has guide rods parallel to it on both sides. The feeding direction of the pressing ring cylinder is towards the side close to the first fixed fixture, so that the pressing head installs the protective ring onto the outer wall of the short handle.

[0015] Preferably, the wire-mounting system includes a second cutting mechanism, which receives and transfers the short handle to align it with a clamping mechanism. The clamping mechanism is used to abut against the upper end of the short handle.

The lifting and transfer system clamps the short handles on the chain conveyor systems. The lifting and transfer system can move perpendicular to the bearing surface and can also move along the conveying direction of the short handles. A guard ring pressing system and a locking wire pusher are sequentially installed on one side of the lifting and transfer system along the conveying direction of the short handles. The system lifts the clamped short shank to the first station of the retaining ring pressing system, and applies the retaining ring to the outer circumference of the short shank. Then, the lifting and transfer system clamps the short shank at the first station again and moves horizontally to transfer the short shank to the second station of the wire clamping system. The wire clamping system clamps the wire to the outer circumference of the short shank, completing the press-fitting of the retaining ring and the assembly of the wire clamp.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] This invention provides a fully automatic assembly device for a short-handled movable joint retainer and a locking screw. Please refer to the attached instruction manual. Figure 1 and 2It includes a support frame 1, on which a chain conveyor system 2 for conveying short handles 6 is provided on the support surface of the support frame 1. The chain conveyor system 2 is used to transport the short handles 6 so that the short handles 6 correspond to the gripping position of the lifting and transferring system 3. In addition, the chain conveyor system 2 can also transport the processed short handles 6 out of the automatic assembly equipment. The lifting and transferring system 3 is slidably mounted on the support surface. The sliding direction of the lifting and transferring system 3 is parallel to the transport direction of the chain conveyor system 2. The lifting and transferring system 3 can also slide in a direction perpendicular to the support surface. On the side of the chain conveyor system 2 close to the lifting and transferring system 3, a protective ring pressing system 4 and a wire clamping system 5 are arranged in sequence. The area where the protective ring is installed on the short handles 6 by the protective ring pressing system 4 is marked as the first station. The area where the wire clamping system 5 is used to clamp the short handles 6 is marked as the second station. The first station and the second station are located on the same horizontal plane, and both the first station and the second station can be connected to the gripping position of the lifting and transferring system 3.

[0039] When processing the short shank 6 using this application, the operator only needs to place the short shank 6 on the chain conveyor system 2. The chain conveyor system 2 transports the short shank 6 to the clamping position of the lifting and transfer system 3. After the lifting and transfer system 3 clamps and fixes the short shank 6, it lifts the short shank 6 vertically so that the short shank 6 is at the same height as the first station. The lifting and transfer system 3 drives the short shank 6 to slide horizontally, aligning the short shank 6 with the first station. The protective ring pressing system 4 receives the short shank 6 and installs the protective ring on the short shank 6. Then, the lifting and transfer system 3 clamps the short shank 6 again and moves the short shank 6 horizontally further so that the short shank 6 aligns with the second station. The wire-clamping system 5 places the wire clamp on the outer periphery of the short shank 6. The lifting and transfer system 3 transfers the processed short shank 6 to the output end of the chain conveyor system 2 and transports the short shank 6 out of the fully automatic assembly equipment.

[0040] Please refer to the instruction manual appendix. Figure 3 The chain conveyor system 2 includes an infeed section 21 and an outfeed section 22, which are respectively located at both ends of the lifting and transfer system 3. A baffle mechanism 23 is provided at the ends of the infeed section 21 and the lifting and transfer system 3. The baffle mechanism 23 includes a baffle cylinder fixed to the bearing surface, and a baffle rod is slidably connected inside the baffle cylinder. The feeding direction of the baffle rod is perpendicular to the transport direction of the infeed section 21. Corresponding locations are provided at the infeed section 21 and the lifting and transfer system 3. In addition, a stop 24 is also provided at the end of the conveying section 22. During the conveying of the short handle 6 in the feeding section 21, when a short handle passes the material blocking mechanism 23, the material blocking cylinder drives the material blocking rod to extend the material blocking rod into the conveying path of the short handle 6, blocking the subsequent material blocking rod from continuing to move forward, so that only one short handle 6 can be engaged with the stop 24. The stop 24 is used to limit the stopping position of the short handle, so that the short handle can be accurately docked with the lifting and transfer system 3.

[0041] Preferably, the material blocking mechanism 23 is equipped with a sensor for monitoring the short handle 6. The sensor is connected to the material blocking cylinder. The sensor can be a laser sensor. When the sensor cannot receive the laser signal reflected from the short handle 6, that is, when one short handle 6 has completely passed through the material blocking mechanism 23, the material blocking cylinder drives the material blocking rod, and the material blocking rod restricts the movement of subsequent short handles 6.

[0042] Please refer to the instruction manual appendix. Figure 4 The lifting and transfer system 3 includes an L-shaped support plate 31. A first slide rail 32 connects the horizontal portion of the support plate 31 to the support surface. The extension direction of the first slide rail 32 is parallel to the transport direction of the short handle 6, allowing the support plate 31 to slide on the support surface. A lifting cylinder 33 is installed on the end face of the support plate 31. The feed direction of the lifting cylinder 33 is perpendicular to the support surface. A linkage plate 37 is connected to the output end of the lifting cylinder 33. The linkage plate 37 is specifically an inverted L-shaped folding plate. The horizontal portion of the linkage plate 37 is fixed to the lifting cylinder 33. The vertical part is located on the side of the support plate 31 away from its horizontal part. The vertical part of the linkage plate 37 is connected to the claw assembly 36, and a second slide rail 35 is provided between the claw assembly 36 and the support plate 31. The second slide rail 35 extends in a direction perpendicular to the support surface. Furthermore, a support plate is connected to the support surface, and a transfer cylinder 34 is fixedly connected to the support plate. The transfer cylinder 34 is connected to the support plate 31 and provides driving force to the support plate 31. The transfer cylinder 34 and the lifting cylinder 33 work together to complete the docking and transfer work of the claw assembly 36 and the short handle 6.

[0043] Preferably, a reinforcing rib is connected between the horizontal and vertical parts of the bearing plate 31. Specifically, there are two reinforcing ribs distributed on both sides of the lifting cylinder 33. Each reinforcing rib is used to improve the strength of the bearing plate 31. A docking block is fixed on the bearing plate 31. A floating joint is connected between the output end of the transfer cylinder 34 and the docking block. The floating joint provides a certain displacement margin for the output end of the transfer cylinder 34, so that there is a buffer area between the transfer cylinder 34 and the docking block. This prevents the stress change at the connection point from being too large when the transfer cylinder 34 drives the bearing plate 31, which could easily lead to the connection breaking and cause equipment failure.

[0044] Please refer to the instruction manual appendix. Figure 5The claw assembly 36 includes a claw back plate 361 fixedly connected to the linkage plate 37. Three sets of claws 362 are provided on the claw back plate 361, with each claw 362 arranged sequentially along the extension direction of the first guide rail. Preferably, each claw 362 has two connecting plates 365 with opposite bending directions. Claw blocks 364 are installed on the bent portions of each connecting plate 365. Each connecting plate 365 is connected to the output ends on both sides of the claw cylinder 363. Each claw cylinder 363 is connected to the claw back plate 361. Each claw block 364 has a mating groove for accommodating the short handle 6, allowing the claw 36... 2. The process of gripping the short handle 6 is more stable and reliable. It should be noted that the spacing between each set of jaws 362 is the same as the distance between the first station and the second station. Each jaw 362 arranged sequentially in the direction away from the feed part 21 is referred to as the first jaw, the second jaw, and the third jaw. Preferably, when the first jaw corresponds to the stop member 24 of the feed part 21, the second jaw and the third jaw correspond to the first station and the second station, respectively. When the first jaw corresponds to the first station, the second jaw corresponds to the second station, and the third jaw corresponds to the receiving end of the feed part 22. Furthermore, two blocking cylinders 38 are provided on the vertical part of the support plate 31. Each blocking cylinder 38 is located on both sides of the linkage plate 37. The feeding direction of each blocking cylinder 38 is perpendicular to the vertical part of the support plate 31. A blocking block is connected to the output end of the blocking cylinder 38. A buffer block is provided on the claw back plate 361. During the upward movement of the claw assembly 36, the blocking cylinder 38 extends the blocking block into the movement path of the claw assembly 36, so that the blocking block abuts against the buffer block, thereby limiting the upward distance of the claw assembly 36.

[0045] In one embodiment of this application, the operator places the short handle 6 on the chain conveyor system 2. The short handle 6 is transported to the stop 24 of the feed section 21. At this time, the first claw aligns with the stop 24 and clamps the short handle 6, which is designated as the first short handle. The lifting and transfer system 3 moves the first short handle to the first station and performs a protective ring pressing operation on the first short handle. The lifting and transfer system 3 aligns the second claw with the first station and clamps the first short handle. Subsequently, the first claw aligns with the stop 24 of the feed section 21 and clamps another short handle 6, designated as the second short handle. The lifting and transfer system 3 aligns the first claw with the first station to install a protective ring on the second short handle, and the second claw aligns with the second station to install a retaining ring on the first short handle. The lifting and transfer system 3 then aligns the first jaw with the aforementioned stop 24. The first jaw grips the third short shank, while the second and third jaws grip the second and first short shanks respectively. The lifting and transfer system 3 aligns the first jaw with the first workstation to install a protective ring on the third short shank 6, and the second jaw with the second workstation to install a retaining wire on the second short shank. The third jaw aligns with the receiving end of the delivery section 22, and the delivery section 22 transports the completed short shank 6 out of the assembly equipment. In other words, through the gripping and placement by the lifting and transfer system 3, the short shanks 6 in each jaw 362 are sequentially placed on the stop 24 of the delivery section, the first workstation, the second workstation, and the receiving end of the delivery section, making the installation operation of this application more continuous and further improving production efficiency.

[0046] Please refer to the instruction manual appendix. Figures 6 to 10 The retaining ring pressing system 4 includes a first cutting mechanism 41 for receiving and transferring the short handle 6. The first cutting mechanism 41 includes a fixed pad 411 connected to the bearing surface. A first cutting base 412 is provided on the end face of the fixed pad 411.

A snap-fit ​​groove is provided on the end face of the first fixing fixture 415 for fixing the short handle 6. A fixing block is provided on the side of the first sliding plate 414 opposite to the first fixing fixture 415. A first cutting cylinder 416 is also provided on the first cutting base 412. The output end of the first cutting cylinder 416 is connected to the fixing block. Preferably, the extension direction of the first cutting guide rail 413 is perpendicular to the first sliding rail 32. The first cutting cylinder 416 pulls the fixing block to transfer the first fixing fixture 415 with the short handle 6 snapped to the bottom of the pressing ring mechanism.

[0047] Furthermore, the retaining ring feeding mechanism 43 includes a column vertically fixed to the bearing surface. A ring cutting carrier plate 431 is connected to the top of the column. A material dropping hole is provided on one side of the first cutting mechanism 41 on the ring cutting carrier plate 431. A feeding cylinder 432 is installed on the material dropping hole, and the port of the feeding cylinder 432 corresponds to the material dropping hole. A retaining ring cutting plate 434 is connected to the side of the ring cutting carrier plate 431 away from the feeding cylinder 432 via a third slide rail 433. The third slide rail 433 is parallel to the first cutting guide rail 413. A retaining ring pusher 435 is detachably provided at one end of the retaining ring cutting plate 434 near the first fixed fixture 415. Specifically, a through hole is provided at the end of the retaining ring cutting plate 434, and the retaining ring pusher 435 is disposed in the through hole. A ring-pushing cylinder 437 is provided on the side of the ring-protecting plate 434 away from the feeding cylinder 432. The output end of the ring-pushing cylinder 437 is connected to the ring-protecting plate 435. In addition, a cutting cylinder 436 is fixed on the end of the ring-cutting carrier plate 431 away from the ring-protecting plate 435. Preferably, the outer periphery of the ring-protecting plate 435 has an annular platform. The end face of the annular platform is lower than the end face of the ring-protecting plate 434. An annular groove is formed between the ring-protecting plate 435 and the ring-protecting plate 434. The cutting cylinder 436 is used to push the ring-protecting plate 434 so that the annular groove corresponds to the dropping hole. The ring falls into the annular groove by its own gravity. The cutting cylinder 436 continues to push the ring-protecting plate 434 so that the annular groove corresponds to the pressing mechanism 42, so that the pressing mechanism 42 picks up the ring.

[0048] Please refer to the instruction manual attached. Figure 10 The pressing mechanism 42 includes two uprights located on both sides of the first cutting mechanism. Each upright is vertically fixed to the fixed pad 411. A pressing ring carrier plate 421 is connected to the top of the uprights. Preferably, the pressing ring carrier plate 421 is located above the cutting ring carrier plate 431. A pressing ring cylinder 422 is provided on the side of the pressing ring carrier plate 421 away from the bearing surface. The output end of the pressing ring cylinder 422 passes through the pressing ring carrier plate 421 and is connected to a pressing plate on the other side of the pressing ring carrier plate 421. Furthermore, a pressing ring holding plate is provided on both sides of the pressing ring cylinder 422. There are two guide rods 424. A linear bearing is provided on the pressure ring carrier plate 421. The guide rods 424 pass through the linear bearing and are connected to the pressure plate on the other side. Each guide rod 424 and the linear bearing makes the movement of the pressure plate more stable. A pressure head 423 is provided on the side of the pressure plate away from the guide rods 424. When the first cutting mechanism 41 aligns the short handle 6 with the pressure head 423, the pressure head 423 moves down and its end abuts against the short handle 6. The pressure head 423 transfers the protective ring connected to its outer wall to the short handle 6.

[0049] Preferably, four ball plungers are provided on the lower outer periphery of the pressure head 423. When the pressure head 423 engages with the retaining ring, the retaining ring abuts against the balls of each ball plunger, pushing the balls into the interior of the plunger. The ball plunger holds the interior of the retaining ring, so that the retaining ring is stably connected to the pressure head 423, preventing the retaining ring from falling off the pressure head 423 when the pressure head 423 is not engaged with the short handle 6.
