Description

Technical Field

[0001] This utility model relates to the field of traction device technology, and in particular to a traction mechanism for workstation equipment. Background Technology

[0002] Workstation equipment refers to various devices used by enterprises in the production site (generally referring to the production line) or warehouse to store production objects or tools. These auxiliary tools are used to hold various parts, raw materials, etc., to meet production needs and facilitate operation by production workers. Workstation equipment is indispensable in every stage of the production process and plays a vital role in scientific management and ensuring safe production.

[0003] Currently, the commonly used workstation equipment in automotive assembly lines mainly includes: tool cabinets, tool carts, parts storage racks, sub-assembly tables, material bins, hoppers, distribution boxes, and transport trolleys. Workstation equipment plays an important role in production operations and logistics transportation, ensuring product quality, eliminating ineffective labor and waste, improving work efficiency and quality, facilitating scientific management, ensuring safe production, and improving the working environment.

[0004] With the continuous development of product logistics and turnover methods, the demand for workstation equipment is no longer limited to fixed placement at the assembly line edge or short-distance transportation from the sub-assembly area to the assembly line edge. It even involves long-distance logistics turnover of product components between different factory areas. In order to facilitate the normal transfer of workstation equipment that holds parts or raw materials, workers generally use a traction device installed at the front end of the workstation equipment to transport it.

[0005] Although the existing traction device serves to transfer workstation equipment, it still has the following shortcomings in actual use: the existing traction device is generally connected to the equipment body by traditional welding method, which is relatively troublesome to install and disassemble, and cannot realize the flexible replacement and maintenance of the traction device, which greatly reduces the practicality of the traction device. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of existing technologies, such as cumbersome installation and disassembly, poor flexibility, and low practicality, and to provide a workstation tool traction mechanism that is reasonably designed, simple in structure, convenient to install and disassemble, has good flexibility, can effectively improve work efficiency, is highly practical, and is suitable for promotion.

[0007] This utility model is achieved through the following technical solution: a workstation tool traction mechanism includes a traction arm, the traction arm having an installation cavity, a connecting shaft movably inserted at the top of the traction arm, a traction hand ring connected to the top of the connecting shaft, and the bottom of the connecting shaft extending into the interior of the installation cavity; a positioning plate is provided inside the installation cavity, the bottom of the connecting shaft movably passes through the positioning plate, and a damping buffer mechanism is provided on the connecting shaft between the positioning plate and the top of the traction arm, the damping buffer mechanism providing buffering during the movement of the connecting shaft; a support base is rotatably connected to the bottom of the traction arm, and a mounting plate located on the outside of the traction arm is vertically connected to one side of the support base, the mounting plate being used to connect the workstation tool; the traction arm can rotate around the support base as a fulcrum, and when the traction arm abuts against the mounting plate, the traction arm is in a vertical state.

[0008] A further improvement of this utility model is that the damping buffer mechanism includes a buffer spring and guide sleeves. Two guide sleeves are provided, which are respectively movably sleeved on the top and bottom ends of the connecting shaft. The upper guide sleeve movably passes through the top end of the traction arm, and the lower guide sleeve movably passes through the positioning plate. The buffer spring is sleeved on the connecting shaft between the two guide sleeves, and both ends of the buffer spring can abut against the guide sleeves. The bottom end of the connecting shaft is threaded with a positioning nut for positioning the guide sleeves.

[0009] A further improvement of this utility model is that the guide sleeve is a stepped sleeve, the two guide sleeves on the traction arm are arranged symmetrically, and the stepped end of the guide sleeve is used to abut against the end of the buffer spring.

[0010] A further improvement of this utility model is that the support base includes a base plate and two side ear plates. The two side ear plates are arranged parallel to each other at both ends of the base plate so that an installation space for the traction arm can be formed between the two side ear plates. One side of the base plate and the two side ear plates is perpendicularly connected to one side of the mounting plate. The bottom end of the traction arm is placed inside the installation space and has a shaft hole. A rotating shaft passes through the shaft hole, and the traction arm is rotatably connected to the side ear plate through the rotating shaft.

[0011] A further improvement of this utility model is that the shaft hole is an oblong hole, and a flip-limiting plate located on the outside of the traction arm is provided on the side of the base plate away from the mounting plate.

[0012] A further improvement of this utility model is that a buffer limiting platform is provided on the bottom plate on the outer side of the flip-limiting plate.

[0013] A further improvement of this utility model is that the mounting plate is a U-shaped plate with the opening facing downwards, and both ends of the mounting plate are provided with elongated bolt holes located on the outer side of the side ear plate.

[0014] A further improvement of this utility model is that a central slot is provided on the side of the mounting plate away from the traction arm.

[0015] A further improvement of this utility model is that the traction arm includes a channel steel body, the top of the channel steel body is a closed structure, and the groove of the channel steel body is the mounting cavity of the traction arm.

[0016] A further improvement of this utility model is that a cover plate for sealing the groove is provided on the top of the traction arm, and a reinforcing plate is provided on the inner wall of the groove at the bottom of the traction arm.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: The design of this mechanism is reasonable and the structure is simple. The installation plate realizes the detachable connection between the mechanism and the workstation equipment, which makes installation and disassembly convenient and flexible, reduces the difficulty of installation and disassembly, and improves work efficiency. In addition, this mechanism has two forms: a vertical form for storage and a horizontal form for traction. The two forms can be flexibly switched according to the actual operation, which makes it highly practical. Furthermore, the design of this mechanism through the damping buffer mechanism has a good buffering function, which can avoid the impact force in the event of a sudden situation during logistics turnover, thereby reducing damage to the workstation equipment and ensuring good safety.

Detailed Implementation

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] Please refer to the attached document. Figure 1-4 The following is a description of a specific embodiment: The workstation traction mechanism of this utility model includes a traction arm 1, which has an inner mounting cavity. Specifically, the traction arm 1 includes a channel steel body, the top of which is a closed structure, and the groove of the channel steel body is the inner mounting cavity of the traction arm 1. The traction arm 1 designed above has a simple overall structure, is easy to source materials, and effectively reduces manufacturing costs.

[0026] A connecting shaft 2 is movably inserted into the top of the traction arm 1. A traction hand ring 3 is connected to the top of the connecting shaft 2. The bottom end of the connecting shaft 2 extends into the interior of the mounting cavity. A positioning plate 4 is provided inside the mounting cavity. The bottom end of the connecting shaft 2 movably passes through the positioning plate 4. A damping buffer mechanism is provided on the connecting shaft 2 between the positioning plate 4 and the top of the traction arm 1. The damping buffer mechanism can provide buffering during the movement of the connecting shaft 2.

[0027] Specifically, the damping buffer mechanism includes a buffer spring 5 and a guide sleeve 6. There are two guide sleeves 6, which are movably sleeved on the top and bottom ends of the connecting shaft 2, respectively. The upper guide sleeve 6 movably passes through the top end of the traction arm 1, and the lower guide sleeve 6 movably passes through the positioning plate 4. The buffer spring 5 is sleeved on the connecting shaft 2 between the two guide sleeves 6, and both ends of the buffer spring 5 can abut against the guide sleeve 6. The bottom end of the connecting shaft 2 is threaded with a positioning nut 7 for positioning the guide sleeve 6.

[0028] When the connecting shaft 2 moves up and down, the damping buffer mechanism designed above can provide effective buffering. That is, when the connecting shaft 2 moves upward, the lower guide sleeve 6 can move upward synchronously under the action of the positioning nut 7. At this time, the upper guide sleeve 6 can abut against the top of the buffer spring 5, thereby enabling the lower guide sleeve 6 to compress the buffer spring 5 to achieve the buffering effect. Conversely, when the connecting shaft 2 moves downward, the upper guide sleeve 6 can move downward synchronously under the action of the traction hand ring 3. At this time, the lower guide sleeve 6 can abut against the bottom of the buffer spring 5, thereby enabling the upper guide sleeve 6 to compress the buffer spring 5 to achieve the buffering effect.

[0029] In addition, the damping buffer mechanism designed above is a detachable structure that can be perfectly matched with the traction arm 1 in the form of a channel steel body. It can be disassembled and assembled after removing the positioning nut 7, which is very convenient. At the same time, the movement distance of the connecting shaft 2 can be adjusted by tightening or loosening the positioning nut 7, and by replacing the guide sleeve 6 with different lengths, which means adjusting the traction length of this traction mechanism, making it flexible and practical.

[0030] The bottom end of the traction arm 1 is rotatably connected to a support base, and a mounting plate 11 located on the outside of the traction arm 1 is vertically connected to one side of the support base. The mounting plate 11 is used to connect the work station equipment. The traction arm 1 can rotate with the support base as the fulcrum, and when the traction arm 1 abuts against the mounting plate 11, the traction arm 1 is in a vertical state.

[0031] Specifically, the support base includes a base plate 8 and side ear plates 9. There are two side ear plates 9, which are arranged parallel to each other at both ends of the base plate 8 so that an installation space for the traction arm 1 can be formed between the two side ear plates 9. One side of the base plate 8 and the two side ear plates 9 is perpendicularly connected to one side of the mounting plate 11. The bottom end of the traction arm 1 is placed inside the installation space and has a shaft hole 101. A rotating shaft 10 passes through the shaft hole 101. The traction arm 1 is rotatably connected to the side ear plates 9 through the rotating shaft 10. The shaft hole 101 is an elongated hole. A flip-limiting plate 12 located on the outside of the traction arm 1 is provided on the side of the base plate 8 away from the mounting plate 11.

[0032] The support base designed above has a simple overall structure, is easy to assemble, and effectively reduces manufacturing costs. At the same time, the mounting plate 11, shaft hole 101, and flip-limiting plate 12 cooperate with each other to effectively limit the traction arm 1. That is, when the traction arm 1 is in a vertical state, the mounting plate 11 and flip-limiting plate 12 are located on both sides of the traction arm 1, respectively, which limits the traction arm 1, thus ensuring that the traction arm 1 always remains in a vertical state. When it is necessary to flip the traction arm 1, since the shaft hole 101 adopts an elongated oval design, there is a certain range of motion between the shaft hole 101 and the rotating shaft 10. Therefore, the traction arm 1 can be lifted up a certain distance. When the bottom end of the traction arm 1 is above the flip-limiting plate 12, the traction arm 1 can be flipped. When the traction arm 1 is flipped to a horizontal state, the top end of the flip-limiting plate 12 can support the traction arm 1, thus ensuring that the traction arm 1 remains in a horizontal state.

[0033] Specifically, the mounting plate 11 is a U-shaped plate with its opening facing downwards, and both ends of the mounting plate 11 have elongated bolt holes 1101 located on the outer side of the side ear plate 9. The mounting plate 11 designed above can be directly clamped onto the workstation fixture through its U-shaped structure, and then securely fixed using bolts through the elongated bolt holes 1101. It can adapt to different types of workstation fixtures and has a wide range of applications.

[0034] The working principle of this utility model is as follows: This mechanism has two forms: when the traction arm 1 is in a vertical state (this is the vertical form, also the conventional form), and when the traction arm 1 is in a horizontal state (this is the horizontal form, also the traction form), the mechanism is in a vertical state. When this mechanism is not in use, the traction arm 1 is in a vertical state, which facilitates the storage of the mechanism by the staff and also greatly saves storage space along the line. When traction work is required, the staff first flips the traction arm 1 to a horizontal state, switching the mechanism to a horizontal form. Then, using the mounting plate 11, the mechanism is installed on the required workstation equipment. After fixing, traction work can be performed using the traction wristband 3.

[0035] It should be noted that when towing multiple workstations, the operator should first install this mechanism on one of the workstations, and then use a trailer to connect the remaining workstations in series with the workstations on which this mechanism is installed. The specific connection method can refer to existing trailer technology. After the connection is completed, the towing operation can be carried out.

[0036] In one embodiment, the guide sleeve 6 is a stepped sleeve, with two guide sleeves 6 symmetrically arranged on the traction arm 1, and the stepped end of the guide sleeve 6 is used to abut against the end of the buffer spring 5. The design of the guide sleeve 6 is more reasonable, as its stepped end can form a positioning function, which can limit the range of motion of the guide sleeve 6, and the stepped end can also increase the contact area with the buffer spring 5.

[0037] In one embodiment, a buffer limiting platform 13 is provided on the bottom plate 8 outside the flip limiting plate 12.

[0038] In one embodiment, a central slot 1102 is provided on the side of the mounting plate 11 away from the traction arm 1. The design of the central slot 1102 can further improve the adaptability of the mounting plate 11.

[0039] In one embodiment, the top of the traction arm 1 is provided with a cover plate 15 for sealing its groove, and a reinforcing plate 14 is provided on the inner sidewall of the groove at the bottom of the traction arm 1. The cover plate 15 protects the buffer spring 5 from damage by foreign objects, and the reinforcing plate 14 effectively improves the overall strength of the traction arm 1, thereby enhancing the strength of the mechanism.
