Description

Technical Field

[0001] This utility model relates to the field of shock absorber manufacturing technology, specifically to a fixed-point feeding unit for automotive shock absorber cores. Background Technology

[0002] With the advancement of automotive technology, automobiles have become an indispensable means of transportation in daily life. To improve driving comfort, modern car chassis systems are generally equipped with shock absorbers. Shock absorbers can provide different damping forces when the vehicle moves up and down, thereby effectively controlling the body's bounce and enabling the vehicle to maintain a stable driving posture at different speeds and road conditions, thus improving ride smoothness and comfort.

[0003] To avoid noise during driving, the shock absorber's support ring consists of a ring body and an iron core (such as...). Figure 6 As shown, the ring body is circular with grooves on its inner wall, and the iron core is embedded in the grooves. The quality of the iron core directly affects the performance of the shock absorber, so the iron core needs to undergo a number of rigorous tests, such as dimensional accuracy testing, appearance defect testing, and material performance testing.

[0004] If automated equipment is used for testing, automatic feeding of the iron core is required. Although existing feeding equipment can achieve basic feeding functions, the iron core output from its feeding end is usually positioned by a limit block. This design inevitably leads to various obstructions around the iron core, and the material handling device is prone to interference with these obstructions, which greatly restricts the material handling method and affects the smoothness of the material handling operation. Utility Model Content

[0005] The purpose of this utility model is to provide a fixed-point feeding unit for automotive shock absorber cores, which can realize automatic feeding of the cores, avoid obstruction around the cores after positioning, reduce restrictions on material picking, and improve the smoothness of material picking.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fixed-point feeding unit for automotive shock absorber cores, comprising a feeding mechanism, a fixed-point mechanism on one side of the feeding mechanism, the fixed-point mechanism including a support plate disposed at the feeding end of the feeding mechanism, a positioning block disposed at the end of the support plate away from the feeding mechanism, a lifting and translating drive assembly disposed below the support plate, the support plate being horizontally fixed at the execution end of the assembly, the width of the support plate being adapted to the diameter of the core, the width of the positioning block being smaller than the diameter of the core and its positioning surface being an arc surface that mates with the core, the support plate being provided with an clearance opening that mates with the positioning block, and insert plates that can move to the sides of the positioning block being formed on both sides of the clearance opening.

[0007] A further improvement of this utility model is that a material-stopping component is provided between the feeding end of the feeding mechanism and the pallet. The material-stopping component includes a support plate disposed between the feeding end of the feeding mechanism and the pallet. A material-stopping cylinder is provided above the support plate. The telescopic end of the material-stopping cylinder is vertically downward and has a pressure block on it. The pressure block can abut against the iron core on the support plate.

[0008] A further improvement of this utility model is that the positioning block has several steps on the side that mates with the support plate. The height of the kick surface of each step is greater than the thickness of the iron core, and the kick surface is an arc surface that mates with the iron core. All the arc surfaces are concentric and have different heights. An adjusting cylinder is provided below the positioning block. The adjusting cylinder is vertically set and its extension end is vertically upward.

[0009] A further improvement of this utility model is that the feeding mechanism is a combination of a vibratory feeder and a linear vibratory feeder, and the pallet is located at the end of the feeding channel of the linear vibratory feeder and its upper end face is flush with the conveying surface of the feeding channel.

[0010] A further improvement of this utility model is that the lifting and translation driving assembly includes a push cylinder arranged along the length direction of the pallet, a lifting cylinder is vertically arranged on the extension end of the push cylinder, and the pallet is arranged on the extension end of the lifting cylinder.

[0011] A further improvement of this utility model is that side plates are provided on both sides of the tray and the positioning block.

[0012] A further improvement of this utility model is that the positioning mechanism further includes a bracket, and the pallet, positioning block and lifting and translation drive assembly are all mounted on the bracket.

[0013] A further improvement of this invention is that a proximity sensor is provided on one side of the positioning block to detect whether an iron core is in contact with it.

[0014] A further improvement of this utility model is that the arc surface is provided with a mounting port, and the proximity sensor is disposed in the mounting port.

[0015] The beneficial effects of this utility model are as follows: This utility model, by setting a fixed-point mechanism, uses a lifting and translation drive component to first drive the pallet and the positioning block to position the iron core on the pallet. Then, the lifting pallet lifts the iron core to an unobstructed height, avoiding obstructions around the positioned iron core. This enables automatic feeding of the iron core, reduces restrictions on subsequent material handling operations, and improves the smoothness of material handling.

[0016] This invention uses a support plate and a positioning block to position the iron core. An abutment is provided to allow the positioning block to be smoothly inserted into the support plate, so that the iron core on the support plate abuts against the curved surface of the positioning block. The positioning surface of the positioning block is a curved surface that mates with the iron core, abutting against the outer circumference of the iron core, thus accurately positioning the iron core in a circumferential direction.

[0017] This invention features a material-stopping component. After one iron core passes under the material-stopping cylinder, the cylinder extends after a set time to press and fix the next iron core, preventing the next iron core from affecting the iron core that has already moved to the tray, reducing interference with the previous iron core, and improving the stability of iron core feeding.

Detailed Implementation

[0025] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1: Combination Figures 1-6It is known that a fixed-point feeding unit for automotive shock absorber cores includes a feeding mechanism 1. A fixed-point mechanism 2 is provided on one side of the feeding mechanism 1. The fixed-point mechanism 2 includes a support plate 3 provided at the feeding end of the feeding mechanism 1. A positioning block 4 is provided at the end of the support plate 3 away from the feeding mechanism 1. A lifting and translating drive assembly is provided below the support plate 3. The support plate 3 is horizontally fixed at the execution end of the assembly. The width of the support plate 3 is adapted to the diameter of the core. The width of the positioning block 4 is smaller than the diameter of the core and its positioning surface is an arc surface 5 that cooperates with the core. The support plate 3 is provided with an clearance opening 6 that cooperates with the positioning block 4. Insert plates 7 that can move to the sides of the positioning block 4 are formed on both sides of the clearance opening 6.

[0027] A clearance opening 6 is provided through the support plate 3, allowing the positioning block 4 to be smoothly inserted. Of the three inner wall surfaces of the clearance opening 6, two are side inner wall surfaces, which can move to either side of the positioning block 4. The inner wall surface between the two side inner wall surfaces is the main clearance surface, which faces the positioning block 4. The distance from the main inner wall surface to the side of the support plate 3 away from the positioning block 4 is greater than half the diameter of the iron core, ensuring that even after the positioning block 4 comes into contact with the main clearance surface of the clearance opening 6 during the movement of the support plate, a large portion of the iron core remains on the support plate 3, ensuring its stability and preventing it from falling. Preferably, the length of the support plate 3 is the same as the diameter of the iron core.

[0028] A material-stopping assembly is also provided between the feeding end of the feeding mechanism 1 and the pallet 3. The material-stopping assembly includes a support plate 8 disposed between the feeding end of the feeding mechanism 1 and the pallet 3. A material-stopping cylinder 9 is disposed above the support plate 8. The telescopic end of the material-stopping cylinder 9 is vertically downward and has a pressure block 10 on it. The pressure block 10 can abut against the iron core on the support plate 8. The support plate is disposed between the feeding channel and the pallet.

[0029] Preferably, a sensor (such as a photoelectric sensor) is provided on one side of the stop cylinder 9 to detect whether an iron core is passing underneath it. When an iron core passes under the stop cylinder 9, the stop cylinder 9 extends after a set time to press and fix the next iron core, so as to prevent the next iron core from affecting the iron core that has been moved to the tray 3. When the iron core on the tray 3 is removed, the stop cylinder 9 resets to allow the next iron core to move to the tray 3.

[0030] The positioning block 4 has several steps on its mating surface with the support plate 3. The height of the kick surface of each step is greater than the thickness of the iron core, and the kick surface is an arc surface 5 that mates with the iron core. All the arc surfaces 5 are concentric and have different heights. An adjusting cylinder 11 is located below the positioning block 4. The adjusting cylinder 11 is vertically positioned with its extension end pointing vertically upwards. By adjusting the cylinder 11 to control the raising and lowering of the positioning block 4, the height of the positioning block 4 can be adjusted, allowing the kick surfaces of different heights to rise and fall to a height that mates with the iron core. This, in turn, limits the iron core to different distances, allowing the positioning position to be adjusted.

[0031] The feeding mechanism 1 is a combination of a vibratory feeder and a linear vibratory feeder, which is a conventional feeding structure in the prior art. The pallet 3 is set at the end of the feeding channel 12 of the linear vibratory feeder, and its upper end face is flush with the conveying surface of the feeding channel 12. Preferably, the stop cylinder 9 is electrically connected to the linear vibratory feeder through a controller. When the stop cylinder 9 extends, the linear vibratory feeder stops feeding.

[0032] Preferably, the lifting and translation drive assembly includes a push cylinder 13 arranged along the length of the support plate 3, and a lifting cylinder 14 vertically arranged on the telescopic end of the push cylinder 13, with the support plate 3 arranged on the telescopic end of the lifting cylinder 14. Optionally, the push cylinder 13 and the lifting cylinder 14 may also be driven components such as telescopic rods.

[0033] Side plates 15 are provided on both sides of the support plate 3 and the positioning block 4. This ensures that the iron core is accurately positioned in the width direction without lateral deviation. The positioning mechanism 2 also includes a bracket 16, on which the support plate 3, the positioning block 4, and the lifting and translation drive assembly are all mounted.

[0034] A proximity sensor 17 is provided on one side of the positioning block 4 to detect whether an iron core is in contact with it. Preferably, the arc surface 5 has a mounting opening, and the proximity sensor 17 is disposed in the mounting opening with its detection surface facing the expected position where the iron core is to contact. The proximity sensor 17 is connected to the controller to confirm whether the iron core has been accurately positioned.

[0035] The working principle of the automotive shock absorber core fixed-point feeding unit provided by this utility model is as follows: During operation, the feeding mechanism 1 feeds the iron core, which is output from the feeding channel 12 of the feeding mechanism 1. The first iron core is pushed onto the pallet 3 by the subsequently output iron core. The stop cylinder 9 extends to block the subsequent iron core, and the feeding mechanism 1 stops conveying. The push cylinder 13 extends to drive the iron core to contact the arc surface of the positioning block 4, and the iron core is accurately positioned in the circumferential direction. Then, the lifting cylinder 14 extends to lift the iron core that has been positioned in the first position on the pallet 3 to the designated height to complete the second positioning and reach the fixed picking position.
