The rotation of the bidirectional threaded rod is precisely controlled by the servo motor, so that the slider can be accurately moved in the limit groove. Therefore, the distance between the two clamping blocks can be adjusted extremely accurately according to the specific size and shape of the clamped object, so that the clamp can adapt to objects of various specifications, whether it is small precision parts or larger workpieces, it can achieve just the right clamping, which improves the versatility and applicability of the clamp, making it suitable for fixing clamps of different sizes.
[0020] The present invention starts the driving motor through the design of the bracket and the buffer part, and the output end of the driving motor drives the bidirectional threaded screw to rotate through the spline, and the round sleeve on the bidirectional threaded screw is connected to the moving plate.

According to actual work requirements, after the bracket is moved to a suitable position, the driving motor is turned off. At this time, the buffer part at the bottom of the bracket plays a certain buffering effect, reducing the impact force and vibration when the bracket moves. The buffer part at the bottom of the bracket plays a vital buffering effect in the process of bracket movement. When the bracket moves quickly or stops along the long slide rail under the action of the driving motor, a certain impact force and vibration will be generated. The buffer part can effectively absorb and disperse this energy, reducing the impact on the bracket itself, the bidirectional threaded screw, the long slide rail and other related components.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.
[0029] like Figures 1 to 6 As shown, the present invention provides a long slide rail special-shaped welding screw support assembly, comprising a base plate 1, a bidirectional threaded screw 2 is arranged inside the base plate 1, a support 3 is arranged on the bidirectional threaded screw 2, a buffer 4 is arranged at the bottom of the support 3, and a clamping mechanism 5 is arranged at the top of the support 3;
[0030] The buffer member 4 includes a base 41, a connecting rod 42, an inclined rod 43 and a buffer rod 44. One end of the connecting rod 42 is rotatably connected to the base 41 through a rotating shaft, and the other end of the connecting rod 42 is rotatably connected to one end of the inclined rod 43 through a rotating shaft. The buffer rod 44 is arranged inside the inclined rod 43.
[0031] The clamping mechanism 5 includes a bidirectional threaded rod 51, a slider 52, a fixing member 53 and a clamping block 54. The inner wall of the slider 52 is threadedly connected to the outer wall of the bidirectional threaded rod 51, the fixing member 53 is fixedly connected to the top surface of the slider 52, and the clamping block 54 is fixedly connected to one side of the fixing member 53.
[0032] The above contents are adopted: the base plate 1 serves as the basic installation platform of the entire fixture 9 bracket 3 assembly, providing a support and fixing foundation for other components. Bidirectional threaded screw 2, long slide rail 6, gasket and other components are installed on it to ensure the structural stability of the entire assembly and the relative position relationship between the components. The bidirectional threaded screw 2 is a key component to achieve the horizontal movement of the bracket 3. By driving the rotation of the driving motor and utilizing the cooperation between the thread and the round sleeve 351, the bracket 3 can be accurately moved in two directions on the base plate 1 along the long slide rail 6, thereby adjusting the position of the clamping mechanism 5 to adapt to work objects of different sizes and positions. Through the design of the clamping mechanism 5, the servo motor is started, and the output end of the servo motor drives the bidirectional threaded rod 51 to rotate in the limit groove. The inner wall of the slider 52 is threadedly connected to the bidirectional threaded rod 51.

The distance between the two clamping blocks 54 is adjusted according to the size and shape of the clamped object. The object to be clamped is placed between the two clamping blocks 54 to ensure that the object is placed correctly. The two-way threaded rod 51 is continuously fine-tuned to make the clamping block 54 gradually approach the object until the clamping block 54 tightly clamps the object. During the clamping process, the tension spring 532 in the fixing member 53 plays a certain buffering and adaptive role, which can make the clamping block 54 better fit the surface of the object and increase the stability of clamping. The rotation of the two-way threaded rod 51 is precisely controlled by the servo motor, so that the slider 52 can be accurately moved in the limit groove, so that the distance between the two clamping blocks 54 can be extremely accurately adjusted according to the specific size and shape of the clamped object, so that the clamp 9 can adapt to objects of various specifications, whether it is a small precision part or a larger workpiece, it can achieve just the right clamping, thereby improving the versatility and applicability of the clamp 9, so that it is suitable for fixing clamps 9 of different sizes.
[0033] like Figures 1 to 6As shown, long slide rails 6 are fixedly connected to both sides of the top of the base plate 1. There are two long slide rails 6, and the two long slide rails 6 are symmetrically distributed on both sides of the top of the base plate 1. Gaskets are fixedly connected to both ends of the base plate 1. A driving motor is fixedly installed on one side of the gasket. The output end of the driving motor is spline-connected to one end of the bidirectional threaded screw 2. Both ends of the bidirectional threaded screw 2 are rotatably connected to the gasket by coaxial bearings. The bracket 3 includes a buffer spring 31, a buffer pressure rod 32, a fixed frame 33 and a sliding block 34. A groove is provided inside the fixed frame 33. The buffer spring 31 is sleeved on the surface of the buffer pressure rod 32. The buffer pressure rod 32 and the buffer spring 31 are both located inside the groove. The sliding block 34 is fixedly connected to the bottom surface of the fixed frame 33. Fixed covers matching the grooves are provided on both sides of the fixed frame 33. One end of the sliding block 34 The side is fixedly connected with a movable plate 35, and the bottom surface of the movable plate 35 is fixedly connected with a circular sleeve 351, the inner wall of the circular sleeve 351 is threadedly connected to the outer wall of the bidirectional threaded screw 2, the bottom surface of the base 41 is connected to the top surface of the movable plate 35, one end of the inclined rod 43 is connected to the inner side wall of the fixed frame 33, and a limiting groove is provided on the top surface of the fixed frame 33, and the bidirectional threaded rod 51 is located inside the limiting groove, and both sides of the fixed frame 33 are fixedly connected with fixed plates, and a servo motor is fixedly installed on one side of the fixed plate, the output end of the servo motor is connected to one end of the bidirectional threaded rod 51, and both ends of the bidirectional threaded rod 51 are rotatably connected to the fixed plate through bearings, and the fixing part 53 includes a baffle 531 and a tension spring 532, one side of the baffle 531 is fixedly connected to one end of the tension spring 532, and the other end of the tension spring 532 is connected to the clamping block 54.
[0034] The above contents are adopted: the slider 52 is threadedly connected with the bidirectional threaded rod 51, converting the rotational motion of the threaded rod into linear motion, driving the fixing part 53 and the clamping block 54 to move, and realizing the operation of clamping and releasing the object. The fixing part 53 fixes the clamping block 54 on the slider 52 on the one hand, and on the other hand, the tension spring 532 therein can provide a certain buffering and adaptive ability when clamping the object, so that the clamping block 54 can better fit the surface of the object, increasing the stability and reliability of clamping. Through the design of the bracket 3 and the buffer 4, the drive motor is started, and the output end of the drive motor drives the bidirectional threaded screw 2 to rotate through the spline. The round sleeve 351 on the bidirectional threaded screw 2 is connected to the moving plate 35. As the screw rotates Due to the threaded connection between the round sleeve 351 and the screw rod, the moving plate 35 drives the bracket 3 to move along the long slide rail 6 on the bottom plate 1. According to actual work requirements, after the bracket 3 is moved to a suitable position, the driving motor is turned off. At this time, the buffer 4 at the bottom of the bracket 3 plays a certain buffering role, reducing the impact force and vibration when the bracket 3 moves. The buffer 4 at the bottom of the bracket 3 plays a vital buffering role in the movement of the bracket 3. When the bracket 3 moves quickly or stops along the long slide rail 6 under the action of the driving motor, a certain impact force and vibration will be generated. The buffer 4 can effectively absorb and disperse this energy, reducing the impact on the bracket 3 itself, the two-way threaded screw rod 2, the long slide rail 6 and other related components;
[0035] The welding screw bracket assembly uses a car seat long slide rail 6, the screw length is 2 meters, and the deviation of the front and rear ends after installation must not exceed 1.7 mm. The theoretical thread position requirement is φ0.15max, which is extremely high. If there is a deviation, the gear box will move from the front to the rear end, and there will be abnormal noise in the quiet room, which will reduce assembly efficiency and cause customer complaints. The screw bracket assembly is composed of a gasket and a bracket welded together. The thread is on the bracket, with an asymmetric structure. Position: There are 3 benchmarks; the bottom gasket will be deformed after welding, and the bottom surface: flat grinding to ensure the contour, positioning with 3 benchmarks, one-time clamping, and machining and threading.
[0036] A long slide rail special-shaped welding screw clamp includes a fixed seat 8, the top surface of the fixed seat 8 is fixedly connected to a fixed frame 81, a clamp 9 is arranged inside the fixed frame 81, a driver is arranged on one side of the fixed frame 81, the clamp 9 includes a first gear 91, a second gear 92 and a clamp rod 93, the first gear 91 and the second gear 92 are meshingly connected, the outer walls of the first gear 91 and the second gear 92 are connected to the clamp rod 93, the first gear 91 and the second gear 92 are both rotatably connected to the fixed frame 81, and one end of the first gear 91 is connected to the output end of the driver through a connecting shaft.
[0037] The clamping rod 93 is a component that directly contacts the clamped object. When the first gear 91 and the second gear 92 rotate under the drive of the driver, the clamping rod 93 moves accordingly. The object is clamped by the relative movement of the two clamping rods 93. Its shape and size can be designed according to the shape and size of the clamped object to ensure that the object can be clamped stably and effectively, and the position of the object is fixed during processing, handling, testing and other operations.
[0038] It is worth noting here that drilling, chamfering and threading can be completed in one clamping. There is no need to process them in multiple steps, which ensures the position of the thread, avoids abnormal noise problems during assembly, and improves product quality.
[0039] The working principle and use process of the present invention are as follows: install the entire fixture 9 bracket 3 assembly on a suitable working platform, ensure that the gaskets at both ends of the bottom plate 1 and the drive motor are firmly fixed, and check whether the long slide rail 6 is installed smoothly without jamming, connect the power supply of the drive motor and the servo motor, and ensure that its control system operates normally, check the lubrication of the bidirectional threaded screw 2, the bidirectional threaded rod 51 and each sliding part, and add an appropriate amount of lubricant if necessary;
[0040] Start the drive motor, and the output end of the drive motor drives the bidirectional threaded screw 2 to rotate through the spline. The round sleeve 351 on the bidirectional threaded screw 2 is connected to the moving plate 35. As the screw rotates, the moving plate 35 drives the bracket 3 to move along the long slide rail 6 on the bottom plate 1 due to the threaded connection between the round sleeve 351 and the screw. According to actual work requirements, after the bracket 3 is moved to a suitable position, the drive motor is turned off. At this time, the buffer 4 at the bottom of the bracket 3 plays a certain buffering role, reducing the impact force and vibration when the bracket 3 moves;
[0041] The servo motor is started, and the output end of the servo motor drives the bidirectional threaded rod 51 to rotate in the limiting groove. The inner wall of the slider 52 is threadedly connected with the bidirectional threaded rod 51. As the threaded rod rotates, the slider 52 moves in the limiting groove along the direction of the bidirectional threaded rod 51. The fixing piece 53 and the clamping block 54 on the top surface of the slider 52 move together with the slider 52. According to the size and shape of the clamped object, the distance between the two clamping blocks 54 is adjusted so that the object can be clamped appropriately. The object to be clamped is placed between the two clamping blocks 54 to ensure that the position of the object is correctly placed. The bidirectional threaded rod 51 is continuously fine-tuned so that the clamping block 54 gradually approaches the object until the clamping block 54 tightly clamps the object. During the clamping process, the tension spring 532 in the fixing piece 53 plays a certain buffering and adaptive role, which can make the clamping block 54 better fit the surface of the object and increase the stability of clamping.
[0042] When the workpiece needs to be clamped or released, the driver starts working. The driver is usually a motor or a pneumatic device, and its output end is connected to the first gear 91 through a connecting shaft. The output end of the driver drives the first gear 91 to rotate. Since the first gear 91 and the second gear 92 are meshed and connected, the rotation of the first gear 91 will drive the second gear 92 to rotate in the opposite direction. This gear transmission mechanism ensures that the clamping rod 93 can move synchronously and coordinately. The clamping rod 93 is connected to the outer walls of the first gear 91 and the second gear 92. When the gears rotate, the clamping rod 93 will move accordingly, thereby clamping or releasing the workpiece.
