Description

Technical Field

[0001] The invention relates to the technical field of screw sleeve tightening, in particular to an automatic tightening device for a wire screw sleeve. Background Art

[0002] With the continuous development of social economy and the continuous advancement of modern science and technology, screw sleeves (such as wire screw sleeves) are widely used in many industries such as machinery, automobiles, aerospace, and home appliances to enhance the strength and durability of threaded connections. As these industries have increasing requirements for product quality and performance, the assembly and installation process of screw sleeves has become increasingly important. Therefore, the development of efficient and accurate screw sleeve installation machines has emerged to meet the needs of large-scale production and high-standard assembly. Traditional tightening equipment mostly relies on manual feeding, and operators need to frequently place the screw sleeves one by one to the tightening position, which not only leads to low production efficiency, but also requires frequent interruption of equipment operation to replenish the screw sleeves due to limited manual operation speed and easy fatigue, which greatly increases the downtime and is not convenient for achieving continuous and stable operation of the equipment. In addition, manual feeding is difficult to ensure the accuracy and stability of the screw sleeve supply. Position deviation is very likely to occur when placing the screw sleeve, such as the screw sleeve tilting, offsetting the predetermined position, etc., and the screw sleeve may fall or be damaged due to operational errors such as uneven force and accidental touch, which will seriously affect the accuracy and quality of the screw sleeve tightening, thereby reducing the qualified rate of the product. Summary of the invention

[0003] 1. Technical issues to be resolved

[0004] In view of the deficiencies in the prior art, the present invention provides an automatic tightening device for a wire screw insert, which solves the problem that traditional tightening devices rely on manual feeding.

[0005] (II) Technical solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] A wire screw insert automatic tightening device, comprising a main frame, a moving assembly is arranged at the front end of the main frame, a tightening assembly is arranged at the front end of the moving assembly, a feeding assembly is arranged at one side of the front end of the tightening assembly, the tightening assembly comprises a connecting frame, a cylinder is fixedly connected to the upper end of the connecting frame, a sliding rod is fixedly connected to the front end of the connecting frame, a lower sliding seat is fixedly connected to the lower end of the sliding rod, and an upper sliding seat is arranged at the upper end of the sliding rod;

[0009] The feeding assembly includes a fixed box, the rear end of the fixed box is fixedly connected to the middle part of one side of the connecting frame, a second push plate is arranged on the other side of the rear end of the inner wall of the fixed box, a first push plate is arranged on one side of the inner wall of the fixed box, a plurality of screw sleeves are arranged on the inner bottom surface of the fixed box, and a sliding pipe is connected through the other side of the front end of the inner wall of the fixed box;

[0010] Through the above technical scheme, when the device is loading the screw sleeve, it only needs to fill the fixed box with screw sleeves in advance, and there is no need for too much manual intervention later. The multi-section electric telescopic rod is driven by an external controller to drive the second push plate to move, so that the screw sleeve on the other side of the inner wall of the fixed box can enter the sliding tube in sequence and in an orderly manner, ensuring the continuity of the screw sleeve supply. When the screw sleeves on this side of the inner wall of the fixed box are all used up, the electric slide rail will start quickly, drive the sliding sleeve to prompt the first push plate to push the screw sleeve to move, and replenish the screw sleeve for the second push plate in time. In this way, the automatic replenishment of the screw sleeve is realized through a reciprocating cycle. This automatic loading method greatly improves production efficiency, reduces downtime caused by manual loading, allows the equipment to operate continuously and stably, and at the same time ensures the accuracy and stability of the screw sleeve supply, avoids position deviations and operational errors that may be caused by manual loading, is conducive to improving the accuracy and quality of screw sleeve tightening, and also reduces manual labor intensity and human cost investment, so that operators can focus more on equipment monitoring and overall production management.

[0011] Preferably, a moving box is fixedly connected to the upper part of the front end of the main frame, a protection box is fixedly connected to the other side of the moving box, an electric push rod is fixedly connected to the inner wall of the protection box, an output end of the electric push rod passes through the protection box to the inside of the moving box and is fixedly connected to a connecting sleeve, a fixing seat is fixedly connected to the front end of the connecting sleeve, and the front end of the fixing seat is fixedly connected to the outer wall of the connecting frame by bolts;

[0012] Through the above technical solution, the electric push rod can accurately control the horizontal position movement of the tightening component, so that the equipment can flexibly adapt to the tightening needs of the screw sleeve, improving the versatility and working range of the equipment. This not only reduces the equipment adjustment time caused by changes in the workpiece position, but also improves the overall production efficiency and reduces production costs.

[0014] Through the above technical solution, the movement mode of the upper slide driven by the cylinder is simple in structure and stable and reliable. The sliding rod provides precise guidance for the up and down movement of the upper slide, ensuring that the connecting seat and the fixed shell can be accurately lifted and lowered. This motion control is conducive to improving the position of the screw sleeve during the tightening process, effectively avoiding thread damage caused by alignment deviation between the tightening head and the screw sleeve, saving maintenance costs and production losses caused by equipment downtime.

[0015] Preferably, a servo motor is fixedly connected to the upper end of the inner wall of the fixed shell, and an output end of the servo motor passes through the fixed shell to the outside of the fixed shell and is fixedly connected to a tightening head;

[0016] Through the above technical solution, the servo motor can control the speed and torque of the tightening head, and can be set according to different screw sleeve specifications and workpiece material requirements. This ensures that each screw sleeve can be tightened with the optimal torque and speed, effectively ensuring the quality consistency of screw sleeve tightening, avoiding product connection problems caused by excessive or insufficient tightening force, and helping to enhance the company's brand image and market competitiveness.

[0017] Preferably, the lower end of the slide tube is fixedly connected to a snap-on shell, wherein the slide tube and the tightening head are both connected to the inside of the snap-on shell, and the front and rear ends of the snap-on shell are hinged to open and close;

[0018] Through the above technical solution, the snap-on shell can effectively prevent the screw sleeve from falling or shifting when it enters, ensuring that the screw sleeve is in the correct position waiting to be grasped by the tightening head. It will only open when the tightening head applies a specific pressure, which provides a stable initial condition for the accurate installation of the screw sleeve, greatly improves the success rate and accuracy of the screw sleeve tightening operation, and reduces the scrap rate caused by inaccurate positioning of the screw sleeve.

[0019] Preferably, a protective pad is fixedly connected to the edge of the inner wall of the fixed box, a baffle is fixedly connected to the rear end of the inner wall of the protective pad, wherein the other side of the baffle is in contact with one side of the second push plate, and a multi-section electric telescopic rod is fixedly connected to the other side of the outer wall of the fixed box, the output end of the multi-section electric telescopic rod passes through the fixed box and the protective pad and is fixedly connected to the rear end of the second push plate;

[0020] Through the above technical solution, the protective pad and baffle can reduce the wear and collision of the screw sleeve during the pushing process and protect the surface quality of the screw sleeve. The multi-section electric telescopic rod provides stable thrust, so that the second push plate can smoothly push the screw sleeve for loading, ensuring the continuity and stability of the loading process.

[0021] Preferably, the first push plate and the second push plate are fitted with adjacent screw sleeves, the upper part of the front end of the fixed box is fixedly connected with an electric slide rail, a sliding sleeve is slidably provided on one side of the lower end of the electric slide rail, and the front end of the upper surface of the first push plate is fixedly connected with the lower end of the sliding sleeve;

[0022] Through the above technical scheme, the close fit between the first push plate and the second push plate and the screw sleeve ensures the orderly arrangement and accurate pushing of the screw sleeve during the loading process. The electric slide rail drives the first push plate to move to replenish the screw sleeve for the second push plate, so that the loading system has an automatic replenishment function, avoiding equipment downtime and waiting due to exhaustion of the screw sleeve. This significantly improves the automation level and production efficiency of the equipment, reduces the frequency of manual intervention, and saves labor costs. At the same time, the automatic replenishment function can also maintain a stable loading rhythm during long-term continuous production.

[0026] 2. The present invention provides an automatic tightening device for a wire screw sleeve. When the screw sleeve is tightened, the cylinder pushes the upper slide to move, and the connecting seat and the fixed plate descend accordingly, thereby driving the fixed shell to descend. During the descent, the upper slide slides smoothly on the outer wall of the slide rod and squeezes the reset spring. At the same time, when the fixed shell is stressed, the connecting seat slides relative to the upper slide and squeezes the connecting spring, so that the device can operate more stably. When faced with the slight differences or uneven conditions that may exist between the screw sleeve and the workpiece thread, the buffering adjustment effect of the spring can ensure that the fixed shell and the tightening head are flexible to adapt, so that the screw sleeve is always screwed into the workpiece thread hole at an appropriate angle and force, thereby improving the reliability of the product thread connection, reducing quality problems caused by insufficient tightening accuracy, and in the long-term and frequent operation process, the buffering of the spring can effectively disperse and reduce the collision and impact between mechanical parts, reduce the wear and fatigue of key parts, reduce the probability of equipment failure, reduce maintenance costs and downtime, and ensure the long-term stable operation of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The upper part of the front end of the upper slide 210 is fixedly connected with a fixing plate 212, the front end of the upper slide 210 is slidably connected with a connecting seat 207, the middle part of the front end of the connecting seat 207 is fixedly connected with a fixing shell 203 by bolts, the other side of the outer wall of the lower slide 209 is fixedly connected with a sliding rod 206, the outer wall of the sliding rod 206 is sleeved with a return spring 205, the other side of the outer wall of the upper slide 210 slides on the outer wall of the sliding rod 206, wherein the upper end of the return spring 205 is in contact with the lower end of the other side of the outer wall of the upper slide 210, and the lower end of the fixing plate 212 is connected to both sides of the upper end of the connecting seat 207 by connecting springs;

[0046] The loading assembly 4 includes a fixed box 401, the rear end of the fixed box 401 is fixedly connected to the middle part of one side of the connecting frame 201, a second push plate is arranged on the other side of the rear end of the inner wall of the fixed box 401, a first push plate 406 is arranged on one side of the inner wall of the fixed box 401, a plurality of screw sleeves 403 are arranged on the inner bottom surface of the fixed box 401, and a sliding pipe is connected through the other side of the front end of the inner wall of the fixed box 401;

[0047] When the screw sleeve 403 is loaded, the device only needs to fill the fixed box 401 with the screw sleeve 403 in advance, and there is no need for much manual intervention later. The multi-section electric telescopic rod 405 is driven by an external controller to drive the second push plate to move, so that the screw sleeve 403 on the other side of the inner wall of the fixed box 401 can enter the inside of the sliding pipe in sequence and in an orderly manner, ensuring the continuity of the supply of the screw sleeve 403. When the screw sleeve 403 on this side of the inner wall of the fixed box 401 is all used up, the electric slide rail 407 will start quickly, driving the sliding sleeve to prompt the first push plate 406 to push the screw sleeve 403 to move, so as to provide the screw sleeve 403 for the first push plate 406 in time. The two push plates replenish the screw sleeve 403, and this cycle is repeated to automatically replenish the screw sleeve 403. This automatic loading method greatly improves production efficiency, reduces downtime caused by manual loading, and allows the equipment to operate continuously and stably. At the same time, it ensures the accuracy and stability of the supply of the screw sleeve 403, avoids position deviations and operational errors that may be caused by manual loading, and is beneficial to improving the accuracy and quality of tightening the screw sleeve 403. It also reduces manual labor intensity and reduces human cost investment, allowing operators to focus more on equipment monitoring and overall production management.

[0048] The upper part of the front end of the main frame 1 is fixedly connected to a moving box 301, and the other side of the moving box 301 is fixedly connected to a protective box 302. The inner wall of the protective box 302 is fixedly connected to an electric push rod 303. The output end of the electric push rod 303 passes through the protective box 302 to the inside of the moving box 301 and is fixedly connected to a connecting sleeve 304. The front end of the connecting sleeve 304 is fixedly connected to a fixing seat 305. The front end of the fixing seat 305 is fixedly connected to the outer wall of the connecting frame 201 by bolts. The electric push rod 303 can accurately control the horizontal position movement of the tightening component 2, so that the equipment can flexibly adapt to the tightening requirements of the screw sleeve 403, which greatly improves the versatility and working range of the equipment. This not only reduces the equipment adjustment time caused by changes in the position of the workpiece, but also improves the overall production efficiency and reduces the production cost.

[0049] The output end of the cylinder 202 passes through the connecting frame 201 and is fixedly connected to the upper end of the upper slide 210. Both sides of the rear end of the upper slide 210 slide with the outer wall of the sliding rod 211. The lower end of the connecting seat 207 fits with the lower end of the upper slide 210. The movement mode of the upper slide 210 driven by the cylinder 202 has a simple structure and is stable and reliable. The sliding rod 211 provides precise guidance for the up and down movement of the upper slide 210, ensuring that the connecting seat 207 and the fixed shell 203 can be accurately lifted and lowered. This motion control is conducive to improving the position of the screw sleeve 403 during the tightening process, effectively avoiding thread damage caused by the alignment deviation between the tightening head and the screw sleeve 403, saving maintenance costs and production losses caused by equipment downtime.

[0050] A servo motor 208 is fixedly connected to the upper end of the inner wall of the fixed shell 203. The output end of the servo motor 208 passes through the fixed shell 203 to the outside of the fixed shell 203 and is fixedly connected to a tightening head. The servo motor 208 can control the speed and torque of the tightening head, and can be set according to the specifications of different screw sleeves 403 and the material requirements of the workpiece. This ensures that each screw sleeve 403 can be tightened with the optimal torque and speed, effectively ensuring the quality consistency of the tightening of the screw sleeve 403, avoiding product connection problems caused by excessive or insufficient tightening force, and helping to enhance the company's brand image and market competitiveness.

[0051] The lower end of the sliding tube is fixedly connected to a snap-on shell 204, wherein the sliding tube and the tightening head are both connected to the inside of the snap-on shell 204, and the front and rear ends of the snap-on shell 204 are hinged to open and close. The snap-on shell 204 can effectively prevent the screw sleeve 403 from falling or shifting when it enters, ensuring that the screw sleeve 403 is in the correct position waiting for the tightening head to grasp it, and it will only open when the tightening head applies a specific pressure. This provides a stable initial condition for the accurate installation of the screw sleeve 403, greatly improves the success rate and accuracy of the tightening operation of the screw sleeve 403, and reduces the scrap rate caused by inaccurate positioning of the screw sleeve 403.

[0052] A protective pad 402 is fixedly connected to the edge of the inner wall of the fixed box 401, and a baffle 404 is fixedly connected to the rear end of the inner wall of the protective pad 402, wherein the other side of the baffle 404 is in contact with one side of the second push plate, and the other side of the outer wall of the fixed box 401 is fixedly connected to a multi-section electric telescopic rod 405, the output end of the multi-section electric telescopic rod 405 passes through the fixed box 401 and the protective pad 402 and is fixedly connected to the rear end of the second push plate, the protective pad 402 and the baffle 404 can reduce the wear and collision of the screw sleeve 403 during the pushing process, and protect the surface quality of the screw sleeve 403, and the multi-section electric telescopic rod 405 provides a stable thrust, so that the second push plate can smoothly push the screw sleeve 403 to load the material, thereby ensuring the continuity and stability of the loading process.

[0053] The first push plate 406 and the second push plate are fitted with adjacent screw sleeves 403, and the upper part of the front end of the fixed box 401 is fixedly connected with an electric slide rail 407, and a sliding sleeve is slidably set on one side of the lower end of the electric slide rail 407. The front end of the upper surface of the first push plate 406 is fixedly connected to the lower end of the sliding sleeve. The close fit between the first push plate 406 and the second push plate and the screw sleeve 403 ensures the orderly arrangement and accurate pushing of the screw sleeve 403 during the feeding process. The electric slide rail 407 drives the first push plate 406 to move to replenish the screw sleeve 403 for the second push plate, so that the feeding system has an automatic replenishment function, which avoids the equipment downtime and waiting due to the exhaustion of the screw sleeve 403, which significantly improves the automation degree and production efficiency of the equipment, reduces the frequency of manual intervention, and saves labor costs. At the same time, the automatic replenishment function can also maintain a stable feeding rhythm during long-term continuous production.

[0054] Working principle: first, the fixed box 401 is filled with wire screw sleeves 403, and the external controller starts the multi-section electric telescopic rod 405 to drive the second push plate to move. Since a protective pad 402 is fixed at the edge of the inner wall of the fixed box 401, and the baffle 404 fixed at the rear end of the inner wall of the protective pad 402 is flush with the second push plate, the screw sleeve 403 can be pushed smoothly. The second push plate pushes the screw sleeve 403 on the other side of the inner wall of the fixed box 401 to move toward the sliding tube, and the screw sleeve 403 enters the interior of the sliding tube in turn, and then enters the snap-on shell 204. When the screw sleeve 403 on the inner wall of the fixed box 401 is used up, the electric slide rail 407 drives the slide sleeve to move, and the slide sleeve drives the first push plate 406 to push the screw sleeve 403 to move, and the second push plate is replenished with screw sleeve 403, and the cycle is repeated to realize automatic loading. The lower parts of both ends of the clamping shell 204 are heavy and hinged, and the screw sleeve 403 can be clamped when there is no external force to prevent it from falling or shifting. The external controller starts the cylinder 202, and the output end of the cylinder 202 pushes the upper slide seat 210 to move downward on the sliding rod 211;

[0055] The connecting seat 207 at the front end of the upper slide 210 and the fixed shell 203 fixed at the middle of the front end of the connecting seat 207 then descend. During the descent process, the upper slide 210 slides on the outer wall of the slide rod 206 and squeezes the reset spring 205. At the same time, after the fixed shell 203 is subjected to force, the connecting seat 207 will slide relative to the upper slide 210 and squeeze the connecting spring. The buffering effect of the spring makes the entire descent process smooth, and the device is more stable, ensuring the accuracy and reliability of the subsequent tightening action. When the fixed shell 203 descends to a certain position, the servo motor 208 inside it is started, and the output end of the servo motor 208 drives the tightening head to rotate. At this time, the tightening head applies downward pressure to the screw sleeve 403 in the clamping shell 204 and rotates it. The clamping shell 204 opens under the force applied by the tightening head, and the screw sleeve 403 is screwed into the threaded hole of the workpiece.

[0056] During the tightening process, the tightening head relies on the servo motor 208 to accurately control the rotation speed and torque to ensure that the screw sleeve 403 is installed according to the preset standard torque and depth, thereby improving the quality and stability of the product's threaded connection. When it is necessary to tighten the screw sleeve 403 at different positions or on workpieces of different specifications, the electric push rod 303 in the protection box 302 is started, and the output end of the electric push rod 303 pushes the connecting sleeve 304 to move, and the connecting sleeve 304 drives the fixed seat 305 to move, and the fixed seat 305 then drives the connecting frame 201 and the entire tightening assembly 2 to move, so that the position of the tightening device can be flexibly adjusted to adapt to diverse production needs and improve the versatility and production efficiency of the equipment.
