Description

Technical Field

[0001] This utility model belongs to the field of automotive manufacturing auxiliary tool technology, and relates to the traction of fixtures and testing tools, specifically to a traction device for automotive process equipment. Background Technology

[0002] In the highly precise and demanding process of automotive body-in-white manufacturing, fixtures and gauges play a crucial role, ensuring the accurate and efficient assembly and welding of various automotive components. Given the flexibility and diversity of automotive production, these fixtures often require frequent movement and adjustments to meet the actual needs of the production line. However, due to the typically large size and weight of these fixtures, manual movement is extremely difficult, time-consuming, labor-intensive, and can potentially cause injury to the equipment or operators.

[0003] To address this issue, traction structures are typically used to assist in the movement of process equipment. These traction structures are usually designed with one end fixed to a power source (such as a motor or hydraulic pump), and the other end securely connected to the component to be towed. The traction force generated by the power source allows heavy automotive process equipment to be easily moved to designated positions on the production line.

[0004] However, in existing traction structure technologies, most are made of monolithic steel, resulting in overly rigid stress characteristics. This rigidity is particularly insufficient in certain applications, such as handling force-sensitive and easily damaged automotive components (e.g., hard rubber strips). When subjected to direct and instantaneous strong forces, these components are prone to cracking or damage due to their inability to withstand sudden stress changes, thus affecting the overall quality and production efficiency of the vehicle.

[0005] Therefore, there is an urgent need for a traction structure that can provide a gentler and more controllable traction force to meet the precision handling requirements of various parts during the manufacturing process of automotive body-in-white. This traction structure should be able to simulate an increasing buffer force, allowing automotive parts to be gradually and smoothly pulled out when traction is applied, thereby effectively avoiding crack formation and improving production efficiency and product quality.

[0037] The present invention will now be described in detail with reference to the accompanying drawings:

[0038] In one embodiment of this utility model, a traction device for automotive manufacturing equipment is disclosed, such as... Figure 1-5 As shown, this device connects a power source to the process equipment to be towed, enabling the towing and movement of the equipment via the power source, which includes a hydraulic cylinder, an electric push rod, a hook, and ropes. The towing device comprises a power unit and a traction unit. The power unit is connected to the power source, and the traction unit is connected to the process equipment to be towed. A force-bearing rod 1 connects the power unit and the traction unit.

[0039] Specifically, in this embodiment, the power unit includes a traction rod 2 and a power connector 3. The two ends of the traction rod 2 are respectively fixedly connected to one end of two force-bearing rods 1. The power connector 3 is disposed on the traction rod 2 and located in the middle of the traction rod 2, and is used to connect to the power source. In this embodiment, the power connector 3 includes a force-bearing bar 31 and a fixing ring 32 fixedly connected to the traction rod 2, as well as a threaded rod 33 fixed to the traction rod 2 and a fixing nut 34 that matches the threaded rod 33. Two force-bearing rods 1 are provided, and the two force-bearing rods 1 are respectively connected to the two ends of the traction rod 2 to form a U-shaped structure.

[0040] It should be noted that the aforementioned force-bearing strip 31 is a flexible traction component, including but not limited to high-strength braided strips, nylon ropes or steel wire ropes, chains, etc., which are intended to provide reliable traction connection while having a certain degree of adaptability and ease of installation.

[0041] In this embodiment, two sets of traction units are provided, each cooperating with two force-bearing rods 1 to achieve buffered traction. The traction unit includes a base plate 4, a buffered traction unit 5, a limiting mechanism 6, and a locking mechanism 7. The base plate 4 is fixedly connected to the other end of the force-bearing rod 1 by welding. At least one pair of buffered traction units 5 are provided, and they are axially symmetrically arranged on the base plate 4 by welding. Each buffered traction unit 5 includes an extension rod 51, a reset elastic element 52, and a force-bearing block 53. One end of the extension rod 51 is connected to the base plate 4 by welding. The reset elastic element 52 is a reset spring, sleeved on the outside of the extension rod 51, with one end connected to the extension rod 51 or the base plate 4 by welding, and the other end connected to the force-bearing block 53. The limiting mechanism 6 includes a limiting rod 61 fixed to each extension rod 51 and a limiting clip 62 adjustablely arranged on the force-bearing block 53. The end of the limiting rod 61 can be stopped by the limiting clip 62. The locking mechanism 7 includes at least two oppositely arranged retaining rings, which are movably connected to the force-bearing block 53 and locked by the adjusting member 8 to form a ring structure for holding the equipment to be pulled.

[0042] Specifically, in this embodiment, the locking mechanism 7 includes a pair of semi-rings: an attached semi-ring 71 fixedly connected to the force-bearing block 53 and a fixed semi-ring 73 movably inserted into the force-bearing block 53 via a plug-in plate 72. The adjusting member 8 consists of an adjusting bolt 81 located at the end of the plug-in plate 73 and an adjusting nut 82 that cooperates with the adjusting bolt 81. A through groove 54 is provided on the force-bearing block 53 in the insertion direction of the plug-in plate 73. The plug-in plate 72 is inserted into the through groove 54, and the adjusting bolt 81 and the adjusting nut 82 are located outside the through groove 54, facilitating the rotation of the adjusting nut 82 to fix the fixed semi-ring 73 and the attached semi-ring 71.

[0043] In addition, in this embodiment, the locking mechanism 7 is further provided with a fine-tuning tightening mechanism 9. At least one fine-tuning tightening mechanism 9 is provided, including a knob 91 rotatably disposed outside the attached half ring 71, and a rack 92 meshing with the knob 91. The knob 91 is located inside the collar 93, and a through hole is opened in the collar 93 at the position corresponding to the rack 92. The rack 92 passes through the through hole. Rotating the knob 91 drives the rack 92 to extend or retract toward the inside of the retaining ring.

[0044] It should be noted that, in order to ensure the clamping effect of the traction device, two fine-tuning and tightening mechanisms 9 are provided in this embodiment, which are respectively symmetrically arranged on the outer periphery of the attached semi-ring 71. This is particularly effective for devices with smooth surfaces or non-circular shapes, ensuring the reliability of the connection under various working conditions.

[0045] In this embodiment, the aforementioned limiting card 62 is adjustablely fixed to the outside of the force-bearing block 53 by the locking member 63. Specifically, the locking member 63 is configured as a fixing screw, and the outside of the force-bearing block 53 is provided with multiple rows of screw holes for cooperating with the fixing screw. A limiting plate 64 is provided at the end of the limiting rod 61, and the upper end of the limiting card 62 is locked onto the upper part of the limiting plate 64 to lock the limiting rod 61. The limiting card 62 is fixed to the force-bearing block 53 by the fixing screw.

[0046] The above describes the traction device of this utility model. During use, the limit card 62 is adjusted at the force block 53 and fixed by the fixing screw. The limit plate 64 at the end of the limit rod 61 is locked by the limit card 62. At the beginning, the traction rod 2 is forced to drive the force rod 1 and the base plate 4, and then the extension rod 51 drives the limit rod 61 and the return spring to move simultaneously for traction. When the limit plate 64 and the limit card 62 are not in contact, the return spring is forced to facilitate traction buffering. After the limit plate 64 and the limit card 62 come into contact, the whole is pulled and traction is performed.

[0047] Specifically, the traction rod 2 is fixedly connected to the power source on both sides. It can be fixed by clamping it onto the threaded rod 33 with the fixing nut 34, or by clamping it with the force-bearing bar 31 and the fixing ring 32 for traction. It is adjusted at the force-bearing block 53 by the limit card 62 and fixed by the fixing screw. The end of the limit rod 61 is clamped by the limit card 62. At the beginning, the traction rod 2 is subjected to force, which drives the force-bearing rod 1 and the base plate 4. Then, the extension rod 51 drives the limit rod 61 and the return spring to move simultaneously for traction. The limit plate 64 and the limit card 62 are used for traction. 2. When there is no contact, the return spring provides traction and force, facilitating traction buffering. After the limit plate 64 and limit card 62 come into contact, the whole is pulled and traction is performed. The device to be pulled is fixed on one side of the locking mechanism 7. After the attached half ring 71 and the fixed half ring 73 are fitted, the fixed nut 34 is rotated to cooperate with the threaded rod 33 for fixation. In traction devices with a smaller fixed radius, the knob 91 of the fine-tuning top tightening mechanism 9 drives the rack 92, causing the rack 92 to extend and squeeze and restrict the device to be pulled, thus completing the fixation.

[0048] The traction device of this utility model has been disclosed through the above description. Compared with the prior art, this utility model has the following advantages:

[0049] 1. This utility model achieves automated switching of working stages through the cooperation of a reset spring and a limiting mechanism. When starting, the reset spring is stretched first to absorb the initial impact force of the power source and gently start the traction equipment, effectively protecting the structure and connection points of the traction equipment. When the limiting rod is locked by the limiting card, the rigid whole is automatically installed to provide solid and reliable traction force, ensuring the stability and accuracy of the traction process.

[0050] 2. This utility model achieves a wide range of diameter adjustment through the cooperation of the attached half ring and the fixed half ring, and achieves a small range of diameter adjustment through the fine-tuning and tightening mechanism. It can hold equipment of different sizes tightly and prevent slippage or rotation during traction. It has good adaptability and strong versatility, and reduces tooling investment.

[0051] 3. The limiting card of this utility model can be fixed at different positions on the force-bearing block by fixing bolts, and the effective stroke of the limiting rod can be adjusted. For heavy traction equipment, it can effectively reduce the buffer stroke and quickly enter the rigid traction mode. For precision or easily damaged traction equipment, it can increase the buffer stroke and provide a smoother start, combining safety and flexibility.

[0052] 4. The power connector of this utility model offers multiple options and has a wider range of applications;

[0053] 5. The traction unit of this utility model adopts a symmetrically arranged buffer traction unit, which makes the traction force evenly distributed, avoids the traction device from bearing the eccentric load torque, and increases the force-bearing area with the base plate to disperse stress and improve the strength and reliability of the entire device.

[0054] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
