Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, specifically to a rubber ring positioning and installation device for actuators. Background Technology

[0002] In the structure of the car parking actuator, three through holes are provided at the edge of the lower housing. The three through holes are distributed in a triangle. A rubber ring is installed in each of the three through holes. The screw passes through the rubber ring to fix the parking actuator to the vehicle body. The rubber ring has a vibration damping effect, preventing the vibration of the vehicle body from being directly transmitted to the parking actuator.

[0003] On the parking actuator assembly line, the first step is to insert the rubber ring into the through hole of the lower housing. Since the rubber ring is a whole composed of a rubber cylinder and flanges at both ends of the rubber cylinder, the process of pressing the rubber ring into the through hole by a traditional stamping machine is prone to jamming or even partial damage to the rubber ring. This results in low assembly efficiency and the generation of defective rubber rings.

[0004] Therefore, in order to solve the above problems, a rubber ring positioning and installation device for actuators is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a rubber ring positioning and installation device for actuators, which makes the installation process of rubber rings more convenient, reduces the scrap rate of rubber rings, and thus solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The actuator uses a rubber ring for positioning and mounting equipment, including a base. One end of the upper surface of the base is fixedly mounted with a support plate and a first cylinder via a first support frame. The other end of the upper surface of the base is fixedly mounted with a transfer mechanism via a second support frame. The support plate is fixedly mounted with a lifting mechanism and a shaped plate. The push rod end of the first cylinder is fixedly mounted with a pressure cylinder via a movable plate, and the pressure cylinder is correspondingly positioned above the lifting mechanism. The movable plate is mounted with an inspection mechanism. A suction cup is fixedly mounted on the lower side of the transfer mechanism, and a feeding mechanism is mounted on the upper side of the base, with the feeding mechanism located below the suction cup.

[0008] Specifically, the lifting mechanism, pressure cylinder, and suction cup are three in a triangular arrangement, with the shaped plate located in the middle of the three lifting mechanisms.

[0009] Specifically, the lifting mechanism includes a top block, an arc-shaped plate, an electric chuck, and a second cylinder. The electric chuck is fixedly installed on the upper side of the support plate, and the second cylinder is fixedly installed on the lower side of the support plate. Arc-shaped plates are fixedly installed on all four claws of the electric chuck. The push rod of the second cylinder passes through the support plate and the electric chuck, and a top block is fixedly installed at the end of the push rod of the second cylinder.

[0010] Specifically, the inspection mechanism includes an annular plate, stepped columns, and a third cylinder. A pair of third cylinders are fixedly installed on the lower side of the movable plate. The pair of third cylinders are distributed on both sides of the first cylinder. The push rods of the third cylinders pass through the movable plate. The ends of the push rods of the pair of third cylinders are fixedly installed on the same annular plate. Three stepped columns are fixedly installed on the lower side of the annular plate. The stepped columns are inserted into aligned pressure cylinders.

[0011] Specifically, the feeding mechanism includes a turntable, a material box, and a servo motor. The material box is fixedly installed on the upper side of the base via a third support frame. The servo motor is fixedly installed at the center of the lower side of the material box. The output shaft of the servo motor passes through the bottom of the material box, and the turntable is fixedly installed at the end of the output shaft of the servo motor. The turntable is located inside the material box. The top of the turntable has three placement slots. The top of the material box has three through slots for aligning suction cups. The top of the material box has a feeding port on the side away from the first support frame.

[0012] Specifically, the transfer mechanism includes an upper bracket, a first rodless cylinder, a second rodless cylinder, a linear slide rail, and a lower bracket. The linear slide rail and the second rodless cylinder are horizontally fixedly installed on the upper side of the second support frame. The upper bracket is fixedly installed between the slide rail and the slide of the second rodless cylinder. The first rodless cylinder is vertically fixedly installed on the upper bracket. A suction cup is installed on the slide of the first rodless cylinder through the lower bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Through the cooperation of the feeding mechanism, the transfer mechanism and the suction cup, three rubber rings can be transferred to the lifting mechanism for storage at the same time. The transfer process is fast and accurate.

[0015] The liftable pressure cylinder, in conjunction with the shape plate and lifting mechanism, facilitates the fixing of the lower housing and the compression and pushing of the rubber ring, reducing installation difficulty and preventing the rubber ring from being squeezed and broken.

[0016] Inspection agencies can detect whether there is any deformation of the inner hole after the rubber ring is installed, and promptly eliminate unqualified products to avoid affecting the production cycle. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Example content:

[0025] Please see Figure 1 This utility model provides a rubber ring positioning and installation device for actuators, including a base 1. The base 1 is a rectangular steel plate with countersunk holes. Screws passing through the countersunk holes can firmly fix the base 1 to the work position, providing a foundation for the installation of other components.

[0026] One end of the upper surface of the base 1 is fixedly mounted with a support plate 10 and a first cylinder 8 via a first support frame. The support plate 10 is horizontally positioned and the first cylinder 8 is vertically positioned. The other end of the upper surface of the base 1 is fixedly mounted with a transfer mechanism 9 via a second support frame. The support plate 10 is fixedly mounted with a lifting mechanism 3 and a shaped plate 4. The lifting mechanism 3 is used to store and lift the rubber ring, while the top of the shaped plate 4 has a groove that matches the lower housing of the parking actuator, which facilitates the accurate placement of the lower housing.

[0027] The push rod end of the first cylinder 8 is fixedly mounted with a pressure cylinder 5 via a movable plate 6. Correspondingly, the top of the first support frame has a through hole for the push rod of the first cylinder 8 to pass through, and the pressure cylinder 5 is positioned above the lifting mechanism 3. The movable plate 6 is equipped with an inspection mechanism 7. The movable plate 6 is horizontally positioned to transmit the lifting power from the first cylinder 8 to the pressure cylinder 5 and the inspection mechanism 7, so that the pressure cylinder 5 and the inspection mechanism 7 rise and fall synchronously. After the pressure cylinder 5 descends, it is used to press the outer periphery of the through hole of the lower housing, while the inspection mechanism 7 can test whether the installed rubber ring is qualified.

[0028] A suction cup 11 is fixedly installed on the lower side of the transfer mechanism 9, and a feeding mechanism 2 is installed on the upper side of the base 1. The feeding mechanism 2 is located below the suction cup 11. The feeding mechanism 2 is used to distribute the rubber rings continuously conveyed from the external vibrating feeding tray below the suction cup 11. When it is necessary to transfer the rubber rings, the transfer mechanism 9 can transfer the rubber rings to the lifting mechanism 3 for storage, avoiding the fatigue and errors caused by manual placement.

[0029] To match the position of the through hole in the lower housing:

[0030] The lifting mechanism 3, the pressure cylinder 5, and the suction cup 11 are all arranged in a triangular pattern, with the shaped plate 4 located in the middle of the three lifting mechanisms 3. The three suction cups 11 can accurately place the rubber rings into the corresponding lifting mechanisms 3. When the lower housing is placed on the shaped plate 4, the three through holes on the edge correspond to the top of the three lifting mechanisms 3. After the three pressure cylinders 5 descend, they will also press against the outer periphery of the three through holes, ensuring that three rubber rings can be assembled at the same time in one operation, resulting in high work efficiency.

[0031] Please see Figure 2 The structure of lifting mechanism 3:

[0032] The lifting mechanism 3 includes a top block 31, an arc-shaped plate 32, an electric chuck 33, and a second cylinder 34. The electric chuck 33 is fixedly installed on the upper side of the support plate 10, and the second cylinder 34 is fixedly installed on the lower side of the support plate 10. The four claws of the electric chuck 33 are all fixedly installed with arc-shaped plates 32. The push rod of the second cylinder 34 passes through the support plate 10 and the electric chuck 33, and the top block 31 is fixedly installed at the end of the push rod of the second cylinder 34.

[0033] The electric chuck 33 is an existing component consisting of a chuck body, a servo motor, a bevel gear, a bevel gear ring, and four jaws. After the servo motor rotates the bevel gear in the forward and reverse directions, it can drive the meshing bevel gear ring and the flat thread on its back to rotate, so that the four jaws move synchronously along the radial guide groove of the chuck body, which can quickly complete the clamping and releasing actions.

[0034] When the four jaws of the electric chuck 33 move away from each other with the arc-shaped pieces 32, a space for placing the rubber ring is formed between the four arc-shaped pieces 32 and the upper side of the top block 31. When the four arc-shaped pieces 32 move closer to each other, they will compress the circumference of the rubber ring so that the outer circumference of the rubber ring is the same as the through hole size. When the second cylinder 34 lifts the top block 31, it can push the compressed rubber ring into the aligned through hole, making the assembly process smoother.

[0035] Please see Figure 3 The structure of inspection agency 7:

[0036] The inspection mechanism 7 includes an annular plate 71, stepped columns 72, and a third cylinder 73. A pair of third cylinders 73 are fixedly installed on the lower side of the movable plate 6. The pair of third cylinders 73 are distributed on both sides (front and rear) of the first cylinder 8. The push rod of the third cylinder 73 passes through the movable plate 6. The ends of the push rods of the pair of third cylinders 73 are fixedly installed on the same annular plate 71. Three stepped columns 72 are fixedly installed on the lower side of the annular plate 71. The stepped columns 72 are inserted into the aligned pressure cylinders 5. Correspondingly, the movable plate 6 has a through hole that connects to the pressure cylinders 5.

[0037] The stepped column 72 is integrally machined from three columns of different diameters. The diameter of the upper column is the same as the outer circumference of the rubber ring, the diameter of the middle column is the same as the inner circumference of the rubber ring, and the diameter of the lower column is 0.7 times the inner circumference of the rubber ring. The upper column acts as a limit and will not extend into the rubber ring. When the third cylinder 73 is working, it drives the three stepped columns 72 to descend synchronously via the annular plate 71. The lower column and the middle column enter the rubber ring in sequence to detect whether the rubber ring is deformed due to improper installation. This is detected by the gas pressure sensor connected to the third cylinder 73 in the air compressor station.

[0038] Please see Figure 4 The structure of feeding mechanism 2:

[0039] The feeding mechanism 2 includes a turntable 22, a material box 25, and a servo motor 26. The material box 25 is fixedly installed on the upper side of the base 1 by a third support frame. The material box 25 is a disc-shaped shell that is adapted to the turntable 22. The servo motor 26 is fixedly installed at the center of the lower side of the material box 25. The output shaft of the servo motor 26 passes through the bottom of the material box 25, and the turntable 22 is fixedly installed at the end of the output shaft of the servo motor 26. The turntable 22 is located inside the material box 25. The top of the turntable 22 has three placement slots 24. The top of the material box 25 has three through slots 23 that align with the suction cup 11. The top of the material box 25 has a feeding port 21 on the side away from the first support frame.

[0040] When in use, the feeding port 21 is connected to the conveying channel of the external vibrating feeding tray. A rubber ring at the end can be aligned with the feeding port 21. The servo motor 26 has an encoder and rotates counterclockwise (with the top view as a reference) once each time it works. When the three placement slots 24 pass through the feeding port 21 in turn, a rubber ring will fall into the placement slot 24 for storage. After one rotation, the three placement slots 24 are aligned with the through slot 23 respectively. The suction cup 11 can enter the through slot 23 to pick up the rubber ring.

[0041] Please see Figure 5 The structure of transfer mechanism 9:

[0042] The transfer mechanism 9 includes an upper bracket 91, a first rodless cylinder 92, a second rodless cylinder 93, a linear slide rail 94, and a lower bracket 95. The linear slide rail 94 and the second rodless cylinder 93 are horizontally fixed on the upper side of the second support frame, and the linear slide rail 94 and the second rodless cylinder 93 are symmetrically distributed front and rear. The upper bracket 91 is fixedly installed between the slides of the linear slide rail 94 and the second rodless cylinder 93. The first rodless cylinder 92 is vertically fixedly installed on the upper bracket 91. The slide of the first rodless cylinder 92 is equipped with a suction cup 11 through the lower bracket 95.

[0043] The suction cup 11 is connected to an external vacuum generator to generate a negative pressure adsorption force. The linear slide rail 94 and the second rodless cylinder 93 cooperate to move the upper bracket 91 and its components in the horizontal direction to adjust the position of the suction cup 11 in the horizontal direction. Meanwhile, the first rodless cylinder 92 can move the suction cup 11 up and down via the lower bracket 95 to adjust the position of the suction cup 11 in the vertical direction.

[0044] The cylinder, electric chuck 33, and servo motor 26 are all connected to the industrial control computer in this process for coordinated control.

[0045] The working principle of this embodiment:

[0046] Feeding: The servo motor 26 in the feeding mechanism 2 drives the turntable 22 to rotate. The three placement slots 24 receive the rubber rings conveyed by the vibrating feeding tray in sequence. The rotation stops when the rubber rings are aligned with the through slot 23. At the same time, the robotic arm of this station places the lower housing on the shaped plate 4 on the conveyor line. The first cylinder 8 drives the pressure cylinder 5 and the inspection mechanism 7 to the initial position on the upper part of the first support frame, providing transfer space for the placement of the lower housing and the rubber rings.

[0047] Transfer: The second rodless cylinder 93 and the linear slide rail 94 in the transfer mechanism 9 make the suction cup 11 be in the initial position at the right end. The first rodless cylinder 92 moves the suction cup 11 down and presses it against the rubber ring for adsorption and then resets it upward. Then, the suction cup 11 is moved to the left into the first support frame and then moved down to transfer the rubber ring into the lifting mechanism 3 for placement.

[0048] Pressing and assembly: The first cylinder 8 first drives the pressure cylinder 5 to press against the outer periphery of the through hole to fix the lower housing; the electric chuck 33 drives the arc-shaped plate 32 to compress the rubber ring, and then the second cylinder 34 pushes the top block 31 to push the rubber ring into the through hole of the lower housing.

[0049] Inspection: The third cylinder 73 in the inspection mechanism 7 moves the annular plate 71 downward, so that the stepped column 72 is gradually inserted into the rubber ring. The deformation of the rubber ring in the unpositioned state is detected by the pressure sensor to ensure the assembly quality.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting, and the scope of this invention is defined by the appended claims rather than the foregoing description.
