Description

Technical Field

[0001] This utility model relates to the field of automatic assembly technology for front fork components, and in particular to an automatic assembly device for front fork components. Background Technology

[0002] A front fork shock absorber, also known as a front fork, is a shock-absorbing device installed at the front of electric vehicles and motorcycles to reduce vibrations and impacts during vehicle operation. The production process of a front fork shock absorber mainly consists of four parts: 1. Parts cleaning; 2. Front fork assembly; 3. Lubrication and sealing; 4. Performance testing.

[0003] This application relates to the assembly equipment for the front fork assembly in Part II.

[0004] A fork assembly contains 8 to 10 parts, and these parts have different installation requirements and structural forms, making the fork assembly a medium-to-high complexity assembly structure. Existing automated assembly equipment for fork assemblies uses a linear layout, where all installation stations are arranged in a straight line. This layout allows for more freedom of movement in the gripping mechanism and even allows for the direct use of a six-axis robotic arm for assembly. The design of this equipment is relatively simple and provides ample tolerance and buffer space for parts assembly. However, this layout also has significant drawbacks: low equipment integration, a clear disconnect between different processes, resulting in slow process changeovers, a large footprint, and inconvenient transportation.

[0005] Currently, there is no existing technology that can fully integrate all assembly processes of the fork assembly into a small assembly cabinet. Utility Model Content

[0006] To solve the above-mentioned problems in the prior art, this utility model provides an automatic assembly equipment for front fork components, including: a frame and a turntable mechanism; The turntable mechanism includes: a first drive motor and a loading turntable; The first drive motor drives the loading turntable to rotate and controls the rotation angle, with the rotation axis being axis L; The turntable mechanism includes a loading turntable, which has multiple installation positions distributed around axis L. Each set of installation positions is provided with a fork tube mounting seat and a positioning tube mounting seat. The fork tube is vertically installed on the fork tube mounting seat, and the positioning tube is vertically installed on the positioning tube mounting seat. The frame is provided with multiple installation stations, and each of the multiple installation stations corresponds one-to-one with a multiple installation position; The loading turntable rotates around the axis L, causing the workpiece to switch installation positions.

[0007] Furthermore, the installation stations are as follows: The loading / unloading station is used to attach the fork tube to the fork tube positioning rod and to attach the positioning tube to the positioning tube mounting rod, and to remove the fork assembly. The wear-resistant ring station is equipped with a wear-resistant ring vibrating feeding plate and a wear-resistant ring gripping mechanism to fit the wear-resistant ring onto the positioning tube; The spring station is equipped with a spring vibrating feeding tray and a spring gripping mechanism to attach the spring to the positioning tube.

The assembly station is equipped with a positioning tube gripping mechanism to insert the positioning tube into the fork tube; The finishing station is equipped with a rolling finishing device to reduce the diameter of the opening at the top of the fork tube and prevent the positioning tube from detaching from the fork tube.

[0008] Furthermore, the wear-resistant ring gripping mechanism includes wear-resistant ring grippers, and the wear-resistant ring grippers are provided with at least 3 wear-resistant ring gripping blocks; The wear-resistant ring clamping block has a wear-resistant ring clamping surface, and after the wear-resistant ring clamping claws open, the wear-resistant ring clamping surface abuts against the inner wall surface of the wear-resistant ring.

[0009] Furthermore, the wear-resistant ring clamp has a first limiting surface and a second limiting surface; The first limiting surface protrudes from the wear-resistant ring clamping surface in a direction away from the clamping axis of the wear-resistant ring jaws. When the wear-resistant ring jaws grip the wear-resistant ring, the first limiting surface abuts against the upper end surface of the wear-resistant ring. The second limiting surface protrudes from the wear-resistant ring clamping surface in the direction of the clamping axis of the wear-resistant ring clamping claw. When the wear-resistant ring is installed by the wear-resistant ring clamping claw, the second limiting surface abuts against the upper end face of the boss of the positioning tube.

[0010] Furthermore, the transmission mechanism in the wear-resistant ring gripper has multiple transmission blocks that correspond one-to-one with the wear-resistant ring gripper, and the transmission blocks are directly driven by the cylinder. The wear-resistant ring clamp is connected to the transmission clamp, and the wear-resistant ring clamp directly contacts the wear-resistant ring; The wear-resistant ring clamping block and the transmission clamping block are slidably connected in the vertical direction and are provided with an elastic element. When the first limiting surface or the second limiting surface is blocked, the wear-resistant ring clamping block compresses the elastic element.

[0011] Furthermore, the spring vibrates the feeding tray, controlling the spring to discharge material in a horizontal posture; The spring gripping mechanism has a spring gripper and a flipping mechanism, and the spring gripper has a first posture and a second posture.

[0013] Furthermore, there are multiple saddle-shaped pad stations, and each saddle-shaped pad station corresponds to one of the installation positions.

[0016] The beneficial effects of this utility model are reflected in the fact that it provides a highly integrated automated assembly equipment for front fork components, with an overall footprint far smaller than existing automated assembly equipment for front fork components. Furthermore, by adjusting the clamping mechanism to accommodate the characteristics of each component in the front fork assembly, a cylinder is used to drive the parts, thereby increasing the equipment's operating speed.

[0019] 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.

[0020] Example 1 Reference Figure 1 - Figure 8 .

[0021] An automated assembly equipment for front fork components includes: a frame 1 and a turntable mechanism 2; The turntable mechanism 2 includes: The first drive motor 21 drives the loading turntable 22 to rotate, with the axis of rotation being axis L; The turntable mechanism 2 includes a loading turntable 22, which has multiple mounting positions 221 distributed around the rotation axis L. Each set of mounting positions 221 is provided with a fork tube mounting seat 2211 and a positioning tube mounting seat 2212. The fork tube 51 is vertically mounted on the fork tube mounting seat 2211, and the positioning tube 52 is vertically mounted on the positioning tube mounting seat 2212. The frame 1 is provided with multiple installation stations, and each of the multiple installation stations corresponds one-to-one with a multiple installation position 221; The loading turntable 22 rotates around the axis L, causing the workpiece to switch installation positions.

[0022] In the field of automated assembly, achieving a high degree of integration of assembly stations typically requires a turntable structure. This involves setting up multiple mounting positions 221 on a turntable, with all stations arranged around it. The turntable rotates to transport parts from mounting position 221 to the next station for installation of other parts. When using a turntable assembly system, the stations are distributed at angles. For example, with 10 stations, each station would be spaced 36° apart. This reduces the distance between stations, making it difficult for the gripping mechanism to swing horizontally, and almost impossible to use a six-axis robotic arm for gripping. Therefore, the equipment needs a gripping mechanism compatible with the turntable mechanism 2 to achieve part assembly with minimal movement.

[0023] In this application, a turntable mechanism 2 is provided, which includes a loading turntable 22 and a first drive motor 21. The first drive motor 21 is a servo motor, which can accurately control the rotation angle of the loading turntable 22. The axis of rotation of the loading turntable 22 driven by the first drive motor 21 is axis L. The loading turntable 22 is provided with multiple mounting positions 221, and each mounting position 221 is provided with both a fork tube mounting seat 2211 and a positioning tube mounting seat 2212.

[0024] In this application, the fork tube 51 and positioning tube 52 are pre-placed in the fork tube mounting base 2211 and positioning tube mounting base 2212. During the first few assembly stages, other parts are installed in the positioning tube 52, while the fork tube 51 is not involved in the assembly. After the other parts are assembled, the positioning tube 52 and other parts are directly installed in the fork tube 51. This saves on the loading steps and space required for the fork tube 51. The fork tube 51, as the outer shell of the entire fork, is relatively long and prone to interference during movement, requiring significant clearance, which is detrimental to equipment miniaturization. In this application, the fork tube 51 and positioning tube 52 are pre-installed vertically into the loading turntable 22, saving space for the fork tube 51 loading and gripping mechanisms. The fork tube mounting base 2211 has fork tube mounting holes with the same diameter as the fork tube 51, allowing the fork tube 51 to be directly inserted. The positioning tube mounting base 2212 has positioning tube mounting holes with the same diameter as the boss of the positioning tube 52. The boss of the positioning tube 52 refers to the cylindrical boss at the end of the positioning tube 52. The positioning tube 52 can be understood as a piston rod, and the boss of the positioning tube 52 is the piston head. The fork tube 51 can be understood as the piston lever.

[0025] An open space is reserved in the equipment as a loading / unloading station 31, where loading and unloading are performed manually. Loading refers to installing the fork tube 51 into the fork tube mounting base 2211 and the positioning tube 52 into the positioning tube mounting base 2212. When unloading, the user lifts the positioning tube 52 to remove the fork assembly and can check whether the fork tube 51 is properly closed to ensure that the fork assembly is not loose.

[0026] Furthermore, the frame 1 is provided with a support slide rail 11, which is a circular track with its center located on the axis L; The loading turntable 22 is fixedly provided with a support structure 222, and the support structure 222 and the support slide rail 11 are abutted by a rolling element 223.

[0027] In many assembly steps, there is a pressing action. The installation position 221 is located around the loading turntable 22, and the distance of the axis L of the installation position 221 is about 0.5 meters. This lever arm is much larger than the lever arm connecting the loading turntable 22 and the shaft of the first drive motor 21. Therefore, when the installation position 221 is subjected to greater pressure, it will tilt, causing the fork tube 51 and the positioning tube 52 in other stations to tilt.

[0028] In this embodiment, a support structure 222 is added to the bottom of the loading turntable 22 to provide support for the edge area of ​​the loading turntable 22, ensuring that the loading turntable 22 will not tilt. Simultaneously, the support structure 222 is provided with rolling elements 223, and the frame 1 is provided with a support slide rail 11. The rolling elements 223 roll along the support slide rail 11, ensuring that the loading turntable 22 can rotate smoothly. Specifically, the support structure 222 can be a cylindrical structure, or multiple support columns fixedly connected to the loading turntable 22, and the rolling elements 223 can be ball bearings or rollers rotatably disposed within the support structure.

[0029] Specifically, refer to Figure 1 This automated equipment has at least 9 installation stations, in the following order: 1. Loading / Retrieving Station 31: This station is located at the door opening position of frame 1, where loading and retrieving are performed manually.

[0030] 2. The wear-resistant ring station 32 is equipped with a wear-resistant ring vibrating feeder 321 and a wear-resistant ring gripping mechanism 322, which fits the wear-resistant ring 53 onto the positioning tube 52. The vibrating feeder is an auxiliary feeding device for automatic assembly or automatic processing machinery, also known as a vibrating feeder automatic feeder. It can arrange various small products in an orderly manner, adjust the posture of the products to achieve continuous feeding, provide the correct assembly parts for automatic assembly equipment to complete a product, or cooperate with automatic processing machinery to complete product processing. The wear-resistant ring vibrating feeder 321 outputs the wear-resistant ring 53 in a vertical posture (the axis of the wear-resistant ring 53 is vertical). At this time, the axis of the wear-resistant ring 53 is parallel to the axis of the positioning tube 52. The wear-resistant ring gripping mechanism 322 only needs to perform a translational movement to move the wear-resistant ring 53 directly above the positioning tube 52, and then drive the positioning tube 52 to descend to complete the assembly of the wear-resistant ring 53 and the positioning tube 52.

[0031] 3. Spring station 33 is equipped with a spring vibrating feeding plate 331 and a spring gripping mechanism 332, which attaches the spring 54 to the positioning tube 52.

[0032] 4. The guide sleeve station 34 is equipped with a guide sleeve vibrating feed plate 341, which controls the guide sleeve 55 to discharge material in a vertical posture.

[0033] The guide sleeve gripping mechanism 342 directly grips the circumferential wall of the guide sleeve 55, displaces it, moves the guide sleeve 55 to directly above the positioning tube 52, and then lowers it so that the guide sleeve 55 is fitted onto the positioning tube 52.

[0034] 5. The saddle-shaped pad station 35 is equipped with a saddle-shaped pad vibrating feeding plate 351 and a saddle-shaped pad gripping mechanism 352, which fits the saddle-shaped pad onto the positioning tube 52.

[0035] 6. The capping station 36 is equipped with a capping vibrating feeding plate 361 and a capping gripping mechanism 362, which fits the cap 57 onto the positioning tube 52.

[0036] 7. Bushing station 37 is equipped with a bushing vibrating feeder 371, which controls the bushing 58 to discharge in a vertical position.

[0037] The bushing gripping mechanism 372 directly grips the circumferential wall of the bushing 58, displaces it, moves the bushing 58 to directly above the positioning tube 52, and then lowers it so that the bushing 58 is fitted onto the positioning tube 52.

[0038] 8. Assembly station 38 is equipped with a positioning tube gripping mechanism 381, which inserts the positioning tube 52 into the fork tube 51. After the wear-resistant ring 53, spring 54, guide sleeve 55, saddle pad 56, pressure cap 57, and bushing 58 are all installed on the positioning tube 52, the positioning tube 52 and the fork tube 51 arrive at the assembly station 38. The positioning tube gripping mechanism 381 directly grips the positioning tube 52 and moves it upward, then moves it horizontally until the positioning tube 52 is aligned with the fork tube 51 before lowering it.

[0039] 9. The closing station 39 is equipped with a rolling closing device 391 to reduce the diameter of the top opening of the fork tube 51 and prevent the positioning tube 52 from detaching from the fork tube 51. After the fork assembly is assembled, the rolling closing device 391 shrinks the top opening of the fork tube 51. The closed end of the fork tube 51 is smaller than the diameter of the boss of the positioning tube 52, thereby ensuring that the fork tube 51 and the positioning tube 52 will not separate when the positioning tube 52 is picked up.

[0040] Example 2 Reference Figure 1 - Figure 8 .

[0041] The wear-resistant ring gripping mechanism 322 includes a wear-resistant ring gripper 323, and the wear-resistant ring gripper 323 is provided with at least 3 wear-resistant ring clamping blocks 3231; The wear-resistant ring clamping block 3231 has a wear-resistant ring clamping surface 32311.

[0042] Reference Figure 8 The positioning tube 52 can be likened to a piston rod, and the fork tube 51 to a piston lever. The end of the positioning tube 52 has a boss, and the circumferential wall of this boss has an annular groove. A wear-resistant ring 53 is installed in this annular groove (similar to an O-ring). The outer wall of the wear-resistant ring 53 rubs against the inner wall of the fork tube 51. The wear-resistant ring 53 is not a continuous annular structure but has an opening, allowing it to expand. The wear-resistant ring 53 needs to fit into the annular groove of the boss in the positioning tube 52. Therefore, the wear-resistant ring 53 needs to expand through the opening and pass through the circumferential wall of the boss to enter the annular groove. This means that the tooling fixture for the wear-resistant ring 53 cannot directly clamp its outer circumferential surface. Otherwise, the wear-resistant ring 53 will not expand and will not be able to pass through the circumferential wall of the boss in the positioning tube 52.

[0043] Reference Figure 4 and Figure 5 In this application, the wear-resistant ring gripping mechanism 322 has wear-resistant ring grippers 323. The wear-resistant ring grippers 323 are provided with at least three wear-resistant ring clamping blocks 3231. The wear-resistant ring clamping blocks 3231 are inserted into the inner ring of the wear-resistant ring 53. Then, the three wear-resistant ring clamping blocks 3231 move away from the clamping center axis and grip the wear-resistant ring 53 by expansion.

[0044] Furthermore, the wear-resistant ring clamping block 3231 has three functional surfaces: a wear-resistant ring clamping surface 32311, a first limiting surface 32312, and a second limiting surface 32313. The wear-resistant ring clamping surface 32311 serves as the surface that abuts against the inner wall of the wear-resistant ring 53. The first limiting surface 32312 protrudes from the wear-resistant ring clamping surface 32311 in a direction away from the clamping center. After the wear-resistant ring clamping block 32311 is inserted into the wear-resistant ring 53, the first limiting surface 32312 abuts against the upper end surface of the wear-resistant ring 53, thereby controlling the relative position of the wear-resistant ring 53 and the wear-resistant ring clamping block 3231. The second limiting surface 32313 protrudes from the surface near the clamping center. When the second limiting surface 32313 descends towards the boss position of the positioning tube 52, it abuts against the upper end face of the boss of the positioning tube 52, thereby determining the relative position of the wear-resistant ring clamping block 3231 and the positioning tube 52. The relative position of the wear-resistant ring 53 and the wear-resistant ring clamping block 3231 is determined by the first limiting surface 32312. Thus, it is only necessary to control the relative distance between the first limiting surface 32312 and the second limiting surface 32313 during processing to determine the relative distance between the wear-resistant ring 53 and the positioning tube 52, thereby ensuring that the wear-resistant ring 53 can be accurately installed in the annular groove of the positioning tube 52.

[0045] Furthermore, the transmission mechanism in the wear-resistant ring gripper 323 has a plurality of transmission grippers 3232 corresponding one-to-one with the wear-resistant ring grippers 3231, and the transmission grippers 3232 are directly driven by the cylinder. The wear-resistant ring clamp 3231 is connected to the transmission clamp 3232, and the wear-resistant ring clamp 3231 directly contacts the wear-resistant ring 53; The wear-resistant ring clamping block 3231 is slidably connected to the transmission clamping block 3232 in the vertical direction and is provided with an elastic element 3233. When the first limiting surface 32312 or the second limiting surface 32313 is blocked, the wear-resistant ring clamping block 3231 compresses the elastic element 3233.

[0046] The deformation space of the elastic element 3233 reduces the positioning difficulty of the limiting surface and the part, so that the wear ring gripping mechanism 322 can use a cylinder to control the up and down displacement, without the need for precise control of the displacement stroke, resulting in lower cost and faster operation speed.

[0047] Example 3 Reference Figure 1 as well as Figure 6-8 .

[0048] The springs 54 used in the fork assembly are compression springs. When the circumferential walls of two compression springs 54 are pressed together, the springs 54 will insert into the gaps between adjacent springs 54, causing them to become entangled. To address this, the spring vibration feeder 331 of this application feeds the springs 54 in a horizontal position, allowing the ends of the springs 54 to abut against each other along their length, thus preventing the springs 54 from becoming entangled. While this effectively prevents the springs 54 from becoming entangled, it results in the axis of the springs 54 being non-parallel to the axis of the positioning tube 52. Therefore, the spring gripping mechanism 332 not only needs to be able to translate but also needs to be able to flip the springs 54 so that they are in a vertical position before they can be fitted onto the positioning tube 52.

[0049] In this embodiment, the spring gripping mechanism 332 is provided with not only a spring gripper 3321, but also a flipping mechanism 3322.

[0050] It has a first posture and a second posture; In the first posture, the clamping center axis of the spring gripper 3321 is parallel to the axis of the spring 54 when it is discharging. In the second posture, the clamping center axis of the spring gripper 3321 is parallel to the axis of the positioning tube 52; The flipping mechanism 3322 switches the spring gripper 3321 to either the first or the second posture.

[0051] First, it is certain that for the flipping mechanism 3322, the spring 54 must be completely removed from the discharge position of the spring vibrating feed plate 331 before flipping can proceed, ensuring there is no interference. In automated equipment, linear drive components can be either servo motors or cylinders. Servo motors can achieve precise control of displacement distance, but they are more expensive and slower. Cylinders, on the other hand, have extremely fast operating speeds and are cheaper, but they can only be at the furthest or closest end, not in the middle. The flipping spring 54 needs to move at least twice in the horizontal direction, which obviously cannot be achieved by a single cylinder; an additional cylinder is required. In this embodiment, the additional cylinder serves as the flipping cylinder 33221 of the flipping mechanism 3322.

[0052] The flipping mechanism 3322 includes a flipping cylinder 33221, a flipping base 33222, a flipping slider 33225, and a flipping shaft 33226; The flipping base 33222 is provided with a guide rail 33223 and a guide groove 33224; the extension direction of the guide rail 33223 is parallel to the horizontal displacement direction of the spring gripper 3321; The flip slider 33225 is slidably connected to the guide rail 33223; The tilting cylinder 33221 is fixedly connected to the tilting base 33222 and drives the tilting slider 33225 to move. The flipping shaft 33226 is rotatably connected to the flipping slider 33225, and the spring gripper 3321 is fixedly connected to the flipping shaft 33226; The flipping shaft 33226 is provided with an eccentric shaft 33227, the eccentric shaft 33227 is not coaxial with the rotation axis of the flipping shaft 33226, and the eccentric shaft 33227 slides along the guide groove 33224. The guide groove 33224 is divided into three sections: a limiting section, a transition section, and a flipping section. The guiding direction of the limiting segment is parallel to the guiding track 33223; the guiding direction of the flipping segment, and the transition segment smoothly connects the limiting segment and the flipping segment.

[0053] Specifically, the guide path of the guide chute 33224 is L-shaped. After the eccentric shaft 33227 slides along the guide chute 33224 to the corner position (i.e., the transition section), it drives the flipping shaft 33226 and the spring gripper 3321 to rotate. In other words, the flipping cylinder 33221 provides power to the spring gripper 3321 in two directions. First, it drives the spring gripper 3321 to move horizontally (i.e., it drives the spring 54 away from the discharge position of the spring vibrating feed plate 331), and then it drives the spring gripper 3321 to flip (flipping the spring 54 to a vertical position). Through the various transmission components of the flipping mechanism 3322, the spring gripping mechanism 332 can simultaneously separate the spring 54 from the discharge port and flip the spring 54's position using a single cylinder, eliminating the need for an additional rotary servo motor, simplifying the equipment complexity and improving the operating speed.

[0054] Example 4 Reference Figure 1 .

[0055] There are multiple saddle-shaped pad stations 35, and each saddle-shaped pad station 35 corresponds to one of the installation positions 221.

[0056] Different specifications of front fork shock absorbers not only differ in size but also in other performance aspects, resulting in variations in the number of saddle pads 56 installed internally. Therefore, this application provides multiple saddle pad stations 35, such as three, to accommodate different specifications of front fork shock absorbers. If a front fork shock absorber requires only one saddle pad 56, then only one saddle pad station 35 is activated for assembling the saddle pad 56.
