Description

Technical Field

[0001] This utility model relates to the field of track socket production equipment, specifically to a spring assembly machine for the power supply mechanism of a track socket. Background Technology

[0002] In the current manufacturing field of track sockets, the power take-up mechanism, as the core component for realizing power transmission, directly affects the product's performance and production economy due to the assembly precision and efficiency of its internal springs. Springs in the power take-up mechanism are typically used to provide contact pressure, ensuring reliable connection of conductive components. Therefore, they need to be precisely installed within a confined, pre-set space and maintained in a stable compressed state.

[0003] In existing technologies, the installation of springs for power-taking mechanisms is generally done manually. Specifically, the operator must first manually hold the spring and compress it to the target length using finger force. Then, with visual assistance, the compressed spring is aligned with the mounting hole of the power-taking mechanism, slowly inserted, and its position adjusted.

[0004] However, this manual operation mode has several drawbacks. The elastic properties of the spring itself make it prone to displacement or rebound during compression, especially when the spring is small, such as a thin-diameter or thin-walled spring. This results in poor grip stability, requiring continuous application of significant pressure to maintain the compressed state. Furthermore, the installation space of the power-generating mechanism is usually a deep cavity or narrow slot structure, requiring operators to use tweezers or other auxiliary tools for delicate operations. Prolonged operation can easily lead to finger fatigue and even operational errors.

[0005] Secondly, manual operation cannot precisely control the spring compression and installation depth, easily leading to the initial preload of the spring not meeting design requirements. Furthermore, the coaxiality of the spring axis and the mounting hole relies on the operator's visual judgment, often causing jamming or poor contact due to angular deviations, requiring subsequent manual calibration or rework, increasing quality control costs.

[0006] In summary, the installation of power-generating mechanism springs in existing technologies relies on manual operation, resulting in low efficiency, poor precision, and high labor intensity. Therefore, there is an urgent need to develop a specialized device capable of automatic spring feeding, precise positioning, and stable pressing to solve the problem of automated assembly of elastic components in confined spaces and improve the production quality and efficiency of track sockets. Utility Model Content

[0007] This utility model overcomes the shortcomings of the above-mentioned technology and provides a spring assembly machine for the power supply mechanism of a track socket.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A spring assembly machine for a track socket power supply mechanism includes a vibratory feeder and a pressing device connected to the vibratory feeder. The pressing device includes a worktable, a receiving platform mounted on the worktable, a pushing mechanism mounted on the outside of the receiving platform, and a pressing mechanism mounted on the receiving platform. The pressing device is connected to the vibratory feeder through the receiving platform. The pressing device also includes a fixed bracket and a slide block slidably connected to the fixed bracket. The receiving platform, the pushing mechanism, and the pressing mechanism are all connected to the slide block.

[0010] Furthermore, the workbench includes a base and a shelf mounted on the base. The shelf includes a first step and a second step, and a positioning groove is provided at the upper end of the second step.

[0011] Furthermore, a slide rail is installed on the fixed bracket, the slide block is slidably connected to the slide rail, a first cylinder is installed at the upper end of the fixed bracket, and the lower end of the first cylinder is connected to the slide block to drive the slide block to slide relative to the fixed bracket.

[0012] Furthermore, the receiving platform includes a first material channel and a second material channel communicating with the first material channel. The first material channel includes a first channel end and a second channel end. The diameter of the second channel end is smaller than that of the first channel end. The first channel end is connected to the vibrating feeder, and the second channel end is communicating with the second material channel. The receiving platform also includes a top material channel, which is communicating with the second material channel.

[0013] Furthermore, the pushing mechanism includes a support seat mounted on the slide, a second cylinder connected to the support seat, and a top material block connected to the front end of the second cylinder, wherein the front end of the top material block is provided with a pin.

[0014] Furthermore, the pressing mechanism includes a third cylinder mounted on a fixed bracket and a push rod connected to the lower end of the third cylinder, the push rod passing through the receiving platform.

[0015] Furthermore, there are two receiving platforms symmetrically arranged on the left and right, and two pushing mechanisms are arranged on the left and right, respectively located on the outer side of the two receiving platforms.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This project effectively addresses many shortcomings of manual spring installation in existing technologies through the collaborative design and functional integration of various mechanisms. The vibratory feeder automatically and systematically delivers springs to the receiving platform, replacing manual material handling and posture adjustment. This avoids spring misalignment or rebound issues caused by manual operation, significantly improving the stability and efficiency of the feeding process. In the pressing device, the sliding connection structure between the fixed bracket and the slide enables the coordinated movement of the receiving platform, the pushing mechanism, and the pressing mechanism. This allows each mechanism to move synchronously in the vertical direction, simplifying the equipment structure while ensuring the coordination of actions and avoiding potential positional deviations caused by independent driving of multiple mechanisms. The clamping station formed by the lower end of the receiving platform and the worktable stably clamps the power supply mechanism during pressing, providing a reliable workpiece positioning foundation for subsequent pushing and pressing, effectively preventing installation deviations caused by workpiece displacement. The pushing mechanism precisely pushes the springs in the receiving platform to the preset installation position and compresses them, avoiding the inconvenience of manual positioning and operation. The pressing mechanism, in conjunction with the pushing mechanism, stably presses the springs into the confined space of the power-taking mechanism, solving the problems of laborious compression and insufficient precision associated with manual spring compression. The interconnected design of the sliding blocks creates an automated process of feeding, positioning, and pressing, eliminating the need for manual intervention in the spring conveying, pushing, and pressing processes. This not only reduces the labor intensity of operators but also significantly improves the consistency and reliability of spring installation through the precise coordination of the mechanical structures. It fundamentally overcomes the technical bottlenecks of time-consuming, labor-intensive, and inaccurate manual operation, achieving efficient and precise automated assembly of springs for the track socket power-taking mechanism, greatly improving production efficiency.

[0025] like Figures 1 to 5 As shown, this invention provides a spring assembly machine for a track socket power-taking mechanism, mainly including a vibratory feeder and a pressing device 100 connected to the vibratory feeder. The material to be processed in this invention is the power-taking mechanism 200 of the track socket, and the assembly machine is used to install springs 300 on the power-taking mechanism. The vibratory feeder is used for automatic feeding of springs 300. The vibratory feeder is not shown in the figure, but a vibratory feeder commonly used in the art can be used. It is not the focus of this invention, and for the convenience of describing it in conjunction with the drawings, it will not be described in detail here. Users can select a suitable vibratory feeder according to their actual situation. The pressing device 100 includes a worktable 1, a receiving platform 2 installed above the worktable 1, a pushing mechanism 3 installed outside the receiving platform 2, and a pressing mechanism 4 disposed above the receiving platform 2. The pressing device 100 is connected to the vibratory feeder through the receiving platform 2. In practical implementation, the vibratory feeder is connected to the receiving platform 2 via a feeding pipe, utilizing the directional vibration of the vibratory feeder to achieve the orderly arrangement and conveying of the springs 300. The vibratory feeder replaces manual material handling, automating the feeding of the springs 300 and ensuring they enter the receiving platform 2 in a preset posture. The receiving platform 2 receives the springs 300 conveyed by the vibratory feeder and works in conjunction with the workbench to clamp the power extraction mechanism 200. The pushing mechanism 3 pushes the springs 300 in the receiving platform 2 to their corresponding installation positions and compresses them. The pressing mechanism 4 pushes the springs 300 into position downwards from the receiving platform and presses them into the installation slot of the power extraction mechanism 200 placed on the workbench. The pressing device 100 also includes a fixed bracket 5 and a slide block 6 slidably connected to the fixed bracket 5. The receiving platform 2, the pushing mechanism 3, and the pressing mechanism 4 are all connected to the slide block 6. The fixed bracket 5 and the slide block 6 are slidably connected to form a multi-mechanism linkage carrier, which enables the receiving platform 2, the pushing mechanism 3, and the pressing mechanism 4 to move synchronously. The multi-component coordinated action is achieved through a single drive source, which simplifies the mechanical structure, reduces control complexity, and improves the consistency of action.

[0026] As described above, in specific implementation, the manual operator places the spring 300 material on the vibratory feeder in advance. Then, the manual operator places the power taking mechanism 200 on the worktable 1 to achieve preliminary positioning of the workpiece. The pressing device 200 is activated, and the slide 6 slides downward along the fixed bracket 5, driving the receiving platform 2, the pushing mechanism 3, and the pressing mechanism 4 to move downward synchronously. The lower end face of the receiving platform 2 contacts the worktable 1, and the two work together to clamp the power taking mechanism 200, forming a stable processing position. The vibratory feeder is activated, using directional vibration to arrange the spring 300 and transport it through the feeding pipe to the inlet of the receiving platform 2. The spring 300 falls into the receiving platform 2, completing the automated feeding. The pushing mechanism 3 is activated, pushing into the receiving platform 2, pushing the spring 300 in the receiving platform 2 to the installation position in the receiving platform 2, that is, the area above the installation slot of the power taking mechanism 200. During the pushing process, the spring 300 is pre-compressed, so that it is in a compressed state ready for installation. The pressing mechanism 4 moves downward, pushing the pre-compressed spring 300 out of the receiving platform 2 and precisely pressing it into the mounting slot of the power take-up mechanism 200 on the workbench 1, completing the final installation of the spring 300. The downward stroke and pressure of the pressing mechanism 4 are controlled by a mechanical structure to ensure that the installation depth and pre-pressure of the spring 300 meet the design requirements. After pressing, the slide 6 drives all mechanisms to move upward synchronously to reset. The power take-up mechanism 200 with the spring 300 installed is then manually removed, and the equipment enters the next cycle, repeating the above process to achieve continuous production. Throughout the process, the slide 6 acts as a linkage carrier, ensuring that the actions of the receiving platform 2, the pushing mechanism 3, and the pressing mechanism 4 are highly coordinated. When moving downward, the workpiece is clamped and the mechanism is positioned simultaneously; when moving upward, it resets synchronously to prepare for the next cycle. The vibratory feeder, the pushing mechanism 3, and the pressing mechanism 4 achieve seamless connection of the spring 300 from conveying, positioning to pressing through position matching and timing control, forming an efficient and stable automated assembly system.

[0027] like Figure 1 , Figure 2As shown, the workbench 1 includes a base 11 and a shelf 12 mounted on the base 11. The base 11 serves as the basic support component of the workbench 1. Anchor bolts or shock-absorbing pads can be installed on the bottom surface, and the top surface is fixedly connected to the shelf 12 by bolts, welding, or embedded clips. The shelf 12 includes a first step 121 and a second step 122. The first step 121 serves as a limiting reference when the receiving platform 2 descends. Its top surface contacts the lower end surface of the receiving platform 2, forming a path for transmitting clamping force, and at the same time providing a support point for the upper end of the power taking mechanism 200. The second step 122 supports the lower end of the power taking mechanism 200. Through the cooperation of the first step 121 and the second step 122, a stable support is provided for the power taking mechanism 200. A positioning groove 1221 is provided at the upper end of the second step 122, and the shape of the positioning groove 1221 matches the bottom contour of the power taking mechanism 200. The positioning slot 1221 physically limits the position of the power taking mechanism 200, ensuring that the mounting slot of the power taking mechanism 200 is accurately aligned.

[0028] Continue as Figure 1 , Figure 2 As shown, a slide rail 51 is mounted on the fixed bracket 5, and a slide block 6 is slidably connected to the slide rail 51. A first cylinder 52 is mounted on the upper end of the fixed bracket 5, and the lower end of the first cylinder 52 is connected to the slide block 6, thereby driving the slide block 6 to slide relative to the fixed bracket 5. In specific implementation, the first cylinder 52 drives the slide block 6 to slide relative to the fixed bracket 5, thereby driving the material receiving platform 2, the material pushing mechanism 3, and the material pressing mechanism 4 to slide as a whole. The material receiving platform 2 and the worktable 1 cooperate to press the material. The sliding cooperation between the slide rail 51 and the slide block 6 improves the accuracy and smoothness of the slide block 6's movement, reduces friction and shaking during the movement, and ensures the positional accuracy of each mechanism during up and down movement, which is beneficial to improving the accuracy of spring assembly. In specific implementation, two first cylinders 52 are provided. The setting of two first cylinders 52 further enhances the stability and balance of the driving force, reduces the probability of equipment failure, and extends the service life of the equipment. In specific implementation, in order to increase the support points and stability of the slide block 6, two slide rails 51 are symmetrically arranged. The double-row slide rail can better withstand the weight of each mechanism and the impact force during the movement, reduce the deformation and shaking of the slide block 6, and further improve the accuracy of spring assembly.

[0029] like Figures 1-4As shown, the receiving platform 2 includes a first material channel 21 and a second material channel 22 connected to the first material channel 21. In specific implementation, the first material channel 21 slopes downward from left to right, while the second material channel 22 is arranged horizontally, and the end of the first material channel 21 finally connects to the second material channel 22. The first material channel 21 includes a first channel end 211 and a second channel end 212, the diameter of the second channel end 212 being smaller than that of the first channel end 211. That is to say, the first material channel 21 has a stepped variable diameter structure, including a first channel end 211 connected to the vibratory feeder and a second channel end 212 connected to the second material channel 22, wherein the diameter of the second channel end 212 is smaller than that of the first channel end 211 to form a diameter difference for the spring 300 to narrow and transition. The first channel end 211 receives the spring 300 conveyed by the vibratory feeder, and the variable diameter design restricts the spring 300 to pass through only one at a time, avoiding multiple materials from stacking, and ensuring that only one spring 300 enters the second channel end 212 at a time. The constricted structure forces the axis of spring 300 to align with the channel axis, correcting any posture deviations that may occur during vibratory feeding. This effectively solves the problems of material blockage or posture confusion that may occur during vibratory feeding, ensuring that the spring enters the subsequent channel in an upright and orderly manner. After the spring falls into the second material channel 22, its radial movement is restricted by the inner wall of the second material channel 22, forming a stable position to be pushed, awaiting the action of the pushing mechanism 3. The receiving platform 2 also includes a top material channel 23, which is connected to the second material channel 22. In specific implementation, the top material channel 23 is vertically connected to the end of the second material channel 22. The pushing mechanism 3 pushes the spring 300 from the second material channel 22 to the top material channel 23. The lower outlet of the top material channel 23 is directly opposite the mounting hole of the power taking mechanism. The internal space height of the top material channel 23 matches the compressed length of the spring, ensuring that the spring can fall directly into the mounting hole when the pressing mechanism 4 presses down.

[0030] like Figure 1 , Figure 2 As shown, the pushing mechanism 3 includes a support base 31 mounted on the slide 6, a second cylinder 32 connected to the support base 31, and a top material block 33 connected to the front end of the second cylinder 32. A top pin is provided at the front end of the top material block 33. In specific implementation, the support base 31 is L-shaped or flat and is fixed to the side of the slide 6 by bolts or clips. Its bottom surface is reinforced with ribs to enhance rigidity, and the rigid connection prevents shaking during cylinder movement. During operation, the piston rod of the second cylinder 32 extends to push the top material block 33. The top pin inserts into the second material channel 22, contacts the tail of the spring, and pushes it at a constant speed until the spring is fully inserted into the top material channel 23. The precise cooperation between the top pin and the second material channel 22 effectively constrains the radial movement of the spring 300, ensuring that the spring axis coincides with the channel axis during the pushing process.

[0031] Continue as Figure 1 , Figure 2As shown, the pressing mechanism 4 includes a third cylinder 41 mounted on a fixed bracket 5 and a push rod 42 connected to the lower end of the third cylinder 41. The push rod 42 passes through the receiving platform 2. In specific implementation, the push rod 42 passes through the material feeding channel 23 in the receiving platform 2. Driven by the third cylinder 41, the push rod 42 is driven to extend and retract within the material feeding channel 23, thereby pressing the material in the material feeding channel 23. To ensure the stability of the pushing and the accuracy of the spring installation, the push rod 42 is a rectangular straight rod. Correspondingly, the structure of the material feeding channel 23 is also a rectangular straight channel that matches the rectangular straight rod, and the two fit tightly together.

[0032] Reference Figures 1-5 As shown, to achieve synchronous installation of the two springs 300 of the power-taking mechanism 200, two receiving platforms 2 are symmetrically arranged on the left and right, and two pushing mechanisms 3 are arranged on the left and right, respectively located on the outer sides of the two receiving platforms 2. Through the symmetrical design of the receiving platforms 2 and pushing mechanisms 3, the automated installation of the two springs of the power-taking mechanism can be completed in a single station. Compared with the traditional single-spring pressing method, this greatly improves efficiency and avoids symmetry errors caused by manual secondary positioning. This symmetrical layout makes full use of equipment space, achieving synchronous pressing of two springs without increasing the complexity of the slide 6 drive system, thus reducing equipment size. The geometric symmetry design and synchronous control mechanism ensure that the feeding path, pushing distance, and pressing depth of the two springs are completely consistent, solving the consistency problem in multi-spring assembly, and is especially suitable for track socket power-taking mechanisms with high requirements for uniform conductive contact pressure.

[0033] The working principle of this case is described in detail below, in conjunction with the full text:

[0034] The vibratory feeder arranges the springs 300 through directional vibration and transports them to the first material channel 21 of the receiving platform 2 via the feeding pipe. The springs 300 enter the second channel 212 from the first channel end 211, and are selected individually through the first material channel 21, forcing the spring axis to align with the channel axis. Finally, the springs 300 fall from the second channel end 212 into the second material channel 22, awaiting the action of the pushing mechanism 3. The operator places the power-taking mechanism 200 of the spring to be installed on the shelf 12 of the workbench 1, so that the upper end of the power-taking mechanism 200 is embedded in the positioning groove 1221 of the second step 122, and the lower end of the power-taking mechanism 200 is naturally limited to the height of the second step 122 onto the first step 121. The piston rod of the first cylinder 52 extends, driving the slide 6 to slide downwards along the slide rail 51 of the fixed bracket 5. The slide 6 drives the receiving platform 2, the pushing mechanism 3, and the pressing mechanism 4 to move downwards synchronously until the lower end face of the receiving platform 2 contacts the first step 121 of the workbench 1. The piston rod of the second cylinder 32 pushes the top material block 33, causing the ejector pin to insert into the second material channel 22. At a constant speed, the ejector pin pushes the spring 300 along the second material channel 22 into the top material channel 23, compressing the spring 300. The piston rod of the third cylinder 41 drives the ejector rod 42 downwards. The ejector rod 42 passes through the top material channel 23 in the receiving platform 2, pressing the spring 300 into the mounting slot of the power take-up mechanism 200 at a constant speed until the preset pressing depth or pressure is reached. After pressing, each mechanism resets and awaits the next process cycle. Finally, the operator removes the power take-up mechanism 200 with the spring installed, and the equipment automatically starts the next cycle.

[0035] As stated above, this case protects a spring assembly machine for a track socket power supply mechanism, and all technical solutions that are the same as or similar to this case should be considered to fall within the protection scope of this case.
