Description

Technical Field

[0001] This invention relates to the field of positioning device technology, and more particularly to a track positioning device. Background Technology

[0002] In fields such as industrial equipment and rail transportation, the accuracy and stability of track assembly directly affect the safety of equipment operation. However, traditional track positioning methods have long had many problems. Traditional track assembly relies on manual visual adjustment of spacing and is fixed by simple bolts or clips, which easily leads to problems such as poor track parallelism and large spacing errors. A lot of debugging work is required afterward, which seriously affects assembly efficiency.

[0003] Meanwhile, traditional positioning methods lack a reliable initial fixing structure. Before tightening, the track is easily shifted due to external forces, and lateral fixing is mostly rigid clamping, which not only has limited compatibility with specific track widths but also easily damages the track surface. Furthermore, although some positioning devices have spacing adjustment functions, the adjustment mechanism lacks precise guidance, is prone to jamming and shifting, and lacks a self-locking design, making it easy to loosen. Therefore, those skilled in the art have provided a track positioning device to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing a track positioning device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a track positioning device, comprising a mounting frame, a guide rail, a first clamping frame, a threaded tube, a second clamping frame, a mounting cylinder, and a plug tube. The mounting frame has two symmetrically distributed clamping frames below it. Both clamping frames have a track assembly area at their lower ends. A mounting cylinder with its upper end penetrating both clamping frames is located inside the upper end of the track assembly area. A screw is rotatably mounted on one end of the second clamping frame. A threaded tube connected to the first clamping frame is threadedly sleeved on the outer wall of the screw. A bearing seat is located on one end of the second clamping frame. A rotating shaft is rotatably mounted inside the bearing seat. Symmetrically distributed worm gears are sleeved on the outer wall of the rotating shaft. A worm wheel meshing with the worm gears is sleeved on the outer wall of the screw. A piston is slidably mounted inside the mounting cylinder. A plug tube is located at the lower end of the piston. A suction cup is located at the lower end of the plug tube. A handle is located at the front end of the rotating shaft.

[0006] Preferably, both the first clamping frame and the second clamping frame have hollow interiors and are arranged in an arched shape. The upper end of the mounting bracket is provided with a guide rail. The second clamping frame is connected to the guide rail via a corner plate. The upper end of the second clamping frame is provided with a slider that is slidably installed on the outer wall of the guide rail.

[0007] Preferably, the plug tube is connected to the suction cup, the upper end of the piston is hollow, a sealing ring is embedded in the lower end of the mounting cylinder, and the plug tube is slidably installed inside the sealing ring.

[0008] Preferably, the upper end of the mounting cylinder is provided with a support ring and a valve ring, the valve ring is provided with a conical valve core, and the upper end of the valve core is provided with a spring connected to the support ring.

[0009] Preferably, the valve core is provided with a positioning rod at its upper end, the positioning rod is located at the center of the support ring, the upper end of the positioning rod is provided with a top cover that is sleeved on the outside of the mounting cylinder, and both the first clamping frame and the second clamping frame are provided with a top plate connected to the top cover.

[0010] Preferably, a sliding sleeve is embedded inside the mounting cylinder and the first clamping frame. An assembly plate with a 90-degree curved plate shape and its lower end suspended inside the upper end of the plug cylinder is slidably installed inside the sliding sleeve. The inner wall of the plug tube is provided with fixing teeth that are evenly distributed longitudinally. A side rod connected to the assembly plate is provided on one side of both the first clamping frame and the second clamping frame.

[0011] Preferably, the assembly plate has symmetrically distributed bearing seats two at one end inside the mounting cylinder. An mounting shaft is rotatably mounted inside the bearing seat two. A retaining tooth is sleeved on the outer wall of the mounting shaft and engages with the inside of the fixing tooth. A torsion spring is sleeved on the outer side of the mounting shaft, with its two ends connected to the retaining tooth and the bearing seat one, respectively. A limiting plate is provided below the bearing seat two and connected to the assembly plate and located below the retaining tooth.

[0012] Preferably, a connecting plate is provided between the first clamping frame and the second clamping frame. A guide sleeve is embedded inside the connecting plate, and a guide rod is slidably installed inside the guide sleeve. A positioning plate connected to a side rod is provided at one end of the guide rod. A second spring is provided between the positioning plate and the connecting plate, and a pressure plate is provided at one end of the guide rod.

[0013] Preferably, a nut is embedded in one end of both the first clamping frame and the second clamping frame, and a screw rod is threaded inside the nut. A clamping plate is provided on one side of the screw rod.

[0014] Preferably, one end of the clamping plate is provided with a rotating seat, one end of the second screw is rotatably installed inside the rotating seat, and the outer wall of one end of the second screw is provided with rotating rods distributed in a ring array.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] Before installation, the track of the device is placed in the track assembly area inside the first and second clamping frames. After being pushed and positioned to the appropriate position by the clamping plates, the suction cup is squeezed longitudinally. The suction cup is squeezed, and air flows from the plug tube. During the piston push process, the elastic support is squeezed and the valve core is opened, so that the gas inside the installation tube is discharged. Then the valve core is reset by its own elastic element, so that the inside of the installation cylinder is in a negative pressure state. Because the negative pressure of the suction cup and the plug tube is connected, it acts on the track of the device installation through the suction cup, adsorbing and positioning the track of the device installation. Then the side of the clamping plate is fastened to the track of the device installation, so that the track of the device installation is positioned. Since the two tracks of the device installation are located inside the first and second clamping frames, and the first and second clamping frames are parallel, the two tracks of the device installation are automatically corrected after positioning, and the installation spacing is consistent, which reduces the subsequent debugging work and improves the assembly efficiency of the track of the device installation.

[0017] Meanwhile, the clamping frame one and clamping frame two are connected by screw one and threaded cylinder. Under the condition of threaded engagement and the sliding guide of the slider in clamping frame two, the position is adjustable. Moreover, the meshing transmission of worm and worm wheel is self-locking after use. The distance between clamping frame one and clamping frame two can be slowly adjusted with a small stroke during the adjustment process, which is suitable for high-precision assembly needs. Rotating the rotating shaft synchronously drives the two rotating shafts to rotate, and at the same time drives clamping frame two to move, which is convenient to use.

[0018] Meanwhile, as the plug cylinder moves longitudinally, the locking teeth, which rotate in one direction and are elastically reset by the torsion spring, engage with the corresponding fixed teeth for positioning. This prevents the suction cup from adsorbing the track and causing a negative pressure imbalance when the plug cylinder rises and then falls. Pulling the side rod from the outside to move the assembly plate and locking teeth together achieves plug cylinder contact locking and unlocking after track assembly. The equipment is easy to use, adaptable to tracks of different specifications and installation spacing, highly flexible, and convenient for the assembly and positioning of the equipment track.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 13 The present invention provides four embodiments:

[0035] Example 1: A track positioning device includes a mounting frame 1, a guide rail 2, a first clamping frame 3, a threaded tube 4, a second clamping frame 5, a mounting cylinder 17, and a plug tube 18. The mounting frame 1 has symmetrically distributed clamping frames 3 and 5 below it. Both clamping frames 3 and 5 have a track assembly area 40 at their lower ends. The upper end of the track assembly area 40 has a mounting cylinder 17 with its upper end penetrating both clamping frames 3 and 5. A screw 7 is rotatably mounted on one end of clamping frame 2. The screw 7 is externally... A threaded tube 4 with one end connected to the clamping frame 3 is threaded through the wall thread. A bearing seat 10 is provided at one end of the clamping frame 5. A rotating shaft 11 is rotatably installed inside the bearing seat 10. A symmetrically distributed worm gear 13 is sleeved on the outer wall of the rotating shaft 11. A worm wheel 12 that meshes with the worm gear 13 is sleeved on the outer wall of the screw 7. A piston 25 is slidably installed inside the mounting cylinder 17. A plug tube 18 is provided at the lower end of the piston 25. A suction cup 28 is provided at the lower end of the plug tube 18. A handle 9 is provided at the front end of the rotating shaft 11.

[0036] In this embodiment, symmetrical clamping frames 3 and 5 are provided below the mounting frame 1. Both of them have a track assembly area 40 at their lower ends for placing the track to be assembled. One end of clamping frame 5 is rotatably mounted with screw 7. The outer wall of screw 7 is threadedly connected to a threaded tube 4 connected to clamping frame 3. The worm 13 on the outer wall of the rotating shaft 11 meshes with the worm wheel 12 of screw 7. The front end of the rotating shaft 11 is provided with a handle 9, forming a transmission link for spacing adjustment. The upper end of the track assembly area 40 is provided with a mounting cylinder 17 that passes through clamping frames 3 and 5. A piston 25 is slidably mounted inside the cylinder. The lower end of the piston 25 is connected to a plug tube 18. The end of the plug tube 18 is provided with a suction cup 28, which can achieve preliminary positioning by adsorbing the track through negative pressure. The meshing structure of worm 13 and worm wheel 12 has a self-locking characteristic to ensure that there is no loosening after the spacing of clamping frame 3 and clamping frame 5 is adjusted, thus ensuring positioning accuracy.

[0037] Before assembly, rotate the handle 9 at the front end of the rotating shaft 11 to drive the rotating shaft 11 and the worm gear 13 on the outer wall to rotate synchronously. The worm gear 13 meshes with the worm wheel 12 on the screw 7, driving the screw 7 to rotate. The screw 7 is threaded with the threaded tube 4, pulling the clamping frame 3 to move along the guide direction of the clamping frame 5, thus achieving fine adjustment of the distance between the two. Due to the deceleration characteristics of the worm gear 13 and worm wheel 12 transmission, a slow adjustment of a small stroke can be achieved, meeting the high-precision distance requirements of track assembly. Moreover, the meshing structure has a self-locking function, and there is no reverse loosening after adjustment, ensuring the stability of the distance.

[0038] After placing the track to be assembled into the track assembly area 40 of clamping frame 3 and clamping frame 5, press the track down so that it contacts the suction cup 28. The track pushes the suction cup 28, which in turn moves the plug tube 18 and piston 25 upward. The air in the mounting cylinder 17 is squeezed out. After the piston 25 returns to its original position, a negative pressure is formed inside the mounting cylinder 17. The negative pressure is transmitted to the suction cup 28 through the plug tube 18. The suction cup 28 firmly adheres to the track surface, completing the initial positioning of the track and preventing track deviation during subsequent tightening.

[0039] The reduction transmission of worm gear 13 and worm wheel 12 can achieve micron-level fine adjustment of track spacing, adapting to high-precision assembly requirements. The self-locking characteristic of the meshing structure prevents spacing deviation caused by vibration after adjustment. Compared with traditional bolt adjustment, the positioning accuracy is improved. The negative pressure suction cup 28 can closely adhere to the track surface to achieve non-damaging initial positioning, avoiding track displacement in subsequent fastening processes and ensuring assembly consistency. Compared with traditional mechanical clamping, the positioning stability is improved. A single handle 9 can drive the rotating shaft 11 to synchronously drive the worm gear 13 and worm wheel 12 on both sides, realizing synchronous spacing adjustment of clamp frame 1 3 and clamp frame 2 5 without separate operation, improving assembly efficiency and adapting to multi-track batch assembly scenarios. The spacing between clamp frame 1 3 and clamp frame 2 5 can be flexibly adjusted according to track specifications, adapting to the assembly of tracks with different widths and spacings, without the need to change special fixtures, reducing assembly costs.

[0040] Traditional track assembly often involves manual visual adjustment of spacing, which can easily lead to poor track parallelism and large spacing errors. Precise transmission adjustment can ensure that the two tracks are parallel and have consistent spacing, reducing the workload of subsequent debugging. Traditional mechanical clamping can easily damage the track surface and is prone to displacement before tightening. The negative pressure adsorption in Example 1 can achieve non-damaging initial fixation, avoiding track deviation in subsequent processes and ensuring assembly quality. Traditional bolt adjustment is difficult to achieve micro-stroke control and is prone to loosening due to lack of self-locking. The worm gear 13 and worm wheel 12 transmission not only ensures adjustment accuracy but also achieves self-locking and anti-loosening, meeting the assembly requirements of high-precision equipment tracks. Traditional multi-track assembly requires adjusting the fixtures one by one, which is time-consuming. The synchronous adjustment design can achieve synchronous spacing adaptation of the two tracks, greatly improving assembly efficiency.

[0041] Example 2:

[0042] Both the first clamping frame 3 and the second clamping frame 5 have hollow internal structures and are arranged in an arch shape. The upper end of the mounting frame 1 is equipped with a guide rail 2. The second clamping frame 5 is connected to the guide rail 2 through a corner plate. The upper end of the second clamping frame 5 is equipped with a slider 6 that is slidably installed on the outer wall of the guide rail 2.

[0043] The plug tube 18 is connected to the suction cup 28. The upper end of the piston 25 is hollow. The lower end of the mounting cylinder 17 is fitted with a sealing ring 27. The plug tube 18 is slidably installed inside the sealing ring 27.

[0044] The upper end of the mounting cylinder 17 is provided with a support ring 21 and a valve ring 22. The valve ring 22 is provided with a conical valve core 24. The upper end of the valve core 24 is provided with a spring 23 connected to the support ring 21.

[0045] A positioning rod is provided at the upper end of the valve core 24. The positioning rod is located at the center of the support ring 21. A top cover 14 is provided at the upper end of the positioning rod and is sleeved on the outside of the mounting cylinder 17. A top plate 20 connected to the top cover 14 is provided above both the first clamping frame 3 and the second clamping frame 5.

[0046] In this embodiment, the worm gear 13 and worm wheel 12 drive the screw 7 to rotate. When adjusting the distance between the clamping frame 3 and the clamping frame 5, the clamping frame 5 slides along the guide rail 2 at the upper end of the mounting frame 1 through the slider 6 connected by the corner plate. This provides linear guidance for the relative movement of the clamping frame 3 and the clamping frame 5, avoiding the offset and jamming of the clamping frame 3 and the clamping frame 5 when adjusting without guidance in the traditional way. This ensures that the two always move in parallel, and the distance adjustment of the track assembly area 40 is more precise. At the same time, the hollow arch structure of the clamping frame 3 and the clamping frame 5 can disperse the pressure of the track on the clamping frame 3 and the clamping frame 5, and avoid the clamping frame 3 and the clamping frame 2 from being deformed by force, which would affect the positioning accuracy.

[0047] When the track pushes the suction cup 28 to move the plug tube 18 upward, the plug tube 18 slides along the sealing ring 27 at the lower end of the mounting cylinder 17. The sealing ring 27 fits tightly against the outer wall of the plug tube 18 to prevent air from seeping into the mounting cylinder 17 from the gap. The piston 25 moves upward to squeeze the air in the mounting cylinder 17. The high-pressure air pushes open the conical valve core 24 in the valve ring 22. The spring 23 is compressed, and the air is discharged through the gap between the valve core 24 and the valve ring 22. After the air is discharged, the spring 23 releases its elastic force to push the valve core 24 to reset. The conical valve core 24 re-seals the valve ring 22, and a sealed space is formed in the mounting cylinder 17 to ensure that the negative pressure is stable and does not leak. The suction cup 28 continues to adsorb the track.

[0048] The positioning rod at the upper end of the valve core 24 slides along the center of the support ring 21, limiting the lateral displacement of the valve core 24 and preventing misalignment during valve core 24 reset, which could lead to sealing failure. The top cover 14 is fixed to the top plate 20, providing stable support for the positioning rod and ensuring that the valve core 24 is always aligned with the center of the valve ring 22, further ensuring the reliability of the negative pressure seal. Even with multiple adsorption and release operations, the valve core 24 can still be accurately reset without sealing deviation. The cooperation between the slider 6 and the guide rail 2 transforms the sliding friction of the clamp frame 1 3 and clamp frame 2 5 into rolling friction, reducing the friction coefficient and eliminating jamming during adjustment. At the same time, it ensures that clamp frame 1 3 and clamp frame 2 5 always move in parallel, resulting in high parallelism of the track assembly area 40. Compared with the traditional guideless design, the parallelism accuracy is improved, making it suitable for high-precision track assembly.

[0049] The tight fit between the sealing ring 27 and the plug tube 18, along with the automatic sealing of the valve core 24, provides double protection against negative pressure leakage. Even under slight vibration, the negative pressure can be maintained stably. Compared to traditional sealless designs, the probability of adsorption failure is reduced, ensuring that the track positioning does not deviate. The guiding cooperation between the positioning rod and the support ring 21 reduces the reset deviation of the valve core 24, eliminating the risk of misaligned sealing. The spring 23 is a fatigue-resistant elastic component, reducing maintenance frequency and cost. The load-bearing strength of the hollow arched clamping frame 3 and clamping frame 5 is higher than that of the traditional rectangular clamping frame 3 and clamping frame 5, making it suitable for heavy-duty tracks, such as those used in industrial equipment. The metal material of the guide rail 2 and the slider 6 is wear-resistant, ensuring that the guiding accuracy remains stable even after long-term use, making it suitable for complex environments such as workshops and construction sites.

[0050] Traditional clamping frames 1 (3) and 2 (5) lack a guiding structure for adjustment, making them prone to jamming and shifting due to uneven force. This results in significant parallelism errors after track assembly. The guide rail 2 and slider 6 provide guidance, ensuring smooth sliding and parallel movement of clamping frames 1 (3) and 2 (5), thus resolving issues with track parallelism. Traditional negative pressure adsorption lacks a sealing design, allowing air to easily seep in and cause negative pressure loss, preventing the suction cup 28 from maintaining its adsorption capacity. The sealing ring 27 and valve core 24 provide automatic sealing, ensuring stable negative pressure through double leak prevention and resolving track displacement issues caused by adsorption failure. Traditional valve core 24 lacks a positioning structure, making it prone to shifting and jamming during reset, and unable to accurately seal the valve ring 22. The positioning rod guides the valve core 24, ensuring it is always aligned with the valve ring 22, avoiding sealing deviations and resolving the problem of unreliable negative pressure sealing. Traditional positioning structures are prone to bending and deformation when bearing heavy tracks, affecting positioning accuracy. The hollow arched clamping frames 1 (3) and 2 (5) enhance structural strength, making them suitable for heavy track assembly and resolving positioning errors caused by deformation of clamping frames 1 (3) and 2 (5).

[0051] Example 3:

[0052] The mounting cylinder 17 and the clamping frame 1 3 are embedded with a sliding sleeve 15. The sliding sleeve 15 is slidably installed with a ninety-degree curved plate shape and the lower end of the mounting cylinder 17 suspended inside the upper end of the mounting cylinder 17. The inner wall of the plug tube 18 is provided with longitudinally equidistant convex fixing teeth 26. The clamping frame 1 3 and the clamping frame 2 5 are each provided with a side rod 8 connected to the mounting plate 16 on one side.

[0053] The assembly plate 16 is located inside the mounting cylinder 17 and has symmetrically distributed bearing seats 37 at one end. The mounting shaft 29 is rotatably mounted inside the bearing seat 37. The outer wall of the mounting shaft 29 is fitted with a retaining tooth 39 that is engaged inside the fixing tooth 26. The outer side of the mounting shaft 29 is fitted with a torsion spring 38 whose two ends are connected to the retaining tooth 39 and the bearing seat 10 respectively. A limiting plate is provided below the bearing seat 37 and connected to the assembly plate 16 and located below the retaining tooth 39.

[0054] A connecting plate 35 is provided between the first clamping frame 3 and the second clamping frame 5. A guide sleeve 42 is embedded inside the connecting plate 35. A guide rod 34 is slidably installed inside the guide sleeve 42. A positioning plate 41 connected to the side rod 8 is provided at one end of the guide rod 34. A spring 36 is provided between the positioning plate 41 and the connecting plate 35. A pressure plate 43 is provided at one end of the guide rod 34.

[0055] In this embodiment, the one-way locking engagement of the locking teeth 39 and the fixed teeth 26 can withstand the entire weight of the plug tube 18 and the suction cup 28 without loosening, preventing the plug tube 18 from falling and causing negative pressure leakage during negative pressure adsorption. Compared with the traditional non-locking design, the adsorption stability is improved, making it suitable for long-term track assembly scenarios. Only pressing the pressure plate 43 is required for linkage unlocking without disassembling the components. The single unlocking time is short, and the operation efficiency is improved compared with the traditional manual disassembly and locking structure. Moreover, the unlocking action is highly synchronized, and the locking teeth 39 on both sides can disengage from the fixed teeth 26 at the same time, preventing the plug tube 18 from tilting due to single-sided unlocking. The spring 36 is a fatigue-resistant component, ensuring automatic reset after unlocking. The locking teeth 39 and the fixed teeth 26 are made of wear-resistant metal materials, and there is no significant wear or decrease in locking accuracy after long-term use. The service life of the core components is extended, and the maintenance frequency is reduced.

[0056] The fixed teeth 26 are evenly distributed longitudinally to accommodate locking requirements of plug tubes 18 of different lengths. The sliding stroke of the mounting plate 16 can be adjusted via the sliding sleeve 15, allowing for adaptation to plug tubes 18 of different diameters without replacing parts, thus reducing equipment adaptation costs. Traditional negative pressure adsorption without plug tube 18 locking structure is prone to air seepage into the mounting cylinder 17 due to gravity falling, resulting in negative pressure loss and suction cup 28 detachment. The locking teeth 39 completely restrict the downward movement of the plug tube 18, ensuring stable negative pressure and solving the adsorption failure problem. Traditional locking structures require manual removal of screws or clips to unlock, which is cumbersome and time-consuming, affecting the track installation. This system improves efficiency with its push-button linkage unlocking, allowing for one-step operation and significantly enhancing unlocking efficiency. It is suitable for batch track assembly scenarios. Traditional locking structures lack guide limits, causing the locking teeth 39 to easily shift and fail to accurately engage with the fixed teeth 26. The sliding sleeve 15 guides and limits the locking plate, ensuring that the locking teeth 39 are always aligned with the fixed teeth 26, minimizing locking accuracy errors and solving the locking misalignment problem. Traditional unlocking structures lack a reset design, requiring manual repositioning of the locking teeth 39 after unlocking before reuse, which is inconvenient. Spring 2 36 provides elastic reset, automatically returning the locking teeth 39 to their original position after unlocking without additional operation, ensuring normal operation of subsequent locking functions.

[0057] Example 4:

[0058] Nuts 31 are embedded in one end of both clamping frame 3 and clamping frame 5. Screw 2 19 is threaded inside the nut 31. A clamping plate 32 is provided on one side of screw 2 19.

[0059] One end of the clamping plate 32 is provided with a rotating seat 33, and one end of the screw 19 is rotatably installed inside the rotating seat 33. The outer wall of one end of the screw 19 is provided with rotating rods 30 arranged in a ring array.

[0060] In this embodiment, nuts 31 are embedded inside one end of clamping frame 3 and clamping frame 5. Screw 19 is installed on the internal thread of nut 31. An arc-shaped clamping plate 32 is provided on one side of screw 19. A rotating seat 33 is provided at one end of clamping plate 32. The threaded engagement between screw 19 and nut 31 can push clamping plate 32 to move laterally, thereby achieving lateral clamping of the track. A ring array of rotating rods 30 is provided on the outer wall of one end of screw 19 for easy manual rotation and adjustment. The rotating seat 33 allows clamping plate 32 to adaptively adjust its angle as screw 19 rotates, adapting to track surfaces with different curvatures or flatness. Clamping plate 32 is made of elastic and wear-resistant material to avoid rigid contact damage to the track surface, while also enhancing the friction between clamping plate 32 and track, thus improving the fastening stability.

[0061] After the "spacing adjustment" in Example 1 and the "initial positioning by negative pressure adsorption" in Example 2, manually rotate the screw 30 on the outer wall of screw 19 to drive screw 19 to move laterally along the nut 31 inside clamping frame 3 and clamping frame 5. Due to the deceleration characteristics of the screw drive, a small stroke adjustment of the clamping plate 32 can be achieved, ensuring that the clamping plate 32 is accurately aligned with the side wall of the track. The synchronous adjustment of screw 19 in clamping frames 3 and 5 on both sides can apply a uniform clamping force from both sides of the track, avoiding track deviation caused by unilateral force. When the screw 19 pushes the clamping plate 32 closer to the track, if there is a slight curvature or flatness deviation on the track surface, the clamping plate 32 can rotate slightly around the end of the screw 19 via the rotating seat 33 at one end, automatically adapting to the shape of the track surface, ensuring that the clamping plate 32 fits tightly against the side wall of the track, avoiding the loosening caused by excessive gap between the clamping plate 32 and the track in traditional rigid fixing, or the deformation of the track caused by excessive compression. At the same time, the elastic wear-resistant clamping plate 32 can buffer the clamping force and prevent the track surface from being scratched or dented.

[0062] The negative pressure suction cup 28 achieves initial adsorption and positioning from above the track, limiting the vertical displacement of the track. The clamping plate 32 applies clamping force from the side of the track, limiting the horizontal displacement of the track. The two form a dual positioning system of vertical and horizontal positioning. Even if the track is subjected to external force collision during assembly, it can still remain stable, avoiding the displacement risk under the traditional single positioning method and ensuring the accuracy of subsequent assembly processes. The clamping force of the thread drive can be precisely controlled. With the tight fit between the clamping plate 32 and the track, the lateral anti-displacement capability is improved compared with the traditional buckle fixation. The dual positioning system ensures that the track has no vertical or horizontal displacement during assembly, which is suitable for the assembly requirements of high-precision equipment tracks.

[0063] By adjusting the stroke of screw 19, clamp 32 can be adapted to rails of different widths without replacing clamp 32 or clamp frame 3 and clamp frame 5. The adaptive design of rotating seat 33 can be compatible with rails of different surface shapes such as flat and curved surfaces. Compared with traditional special clamps, the adaptation cost is reduced and the adaptation efficiency is improved. The ring array rotary rod 30 is easy to manually rotate and adjust without additional tools. The single tightening time is short. The elastic and wear-resistant clamp 32 avoids rigid contact damage to the rail. Even with repeated clamping, there are no scratches on the rail surface, ensuring the appearance and performance of the rail after assembly are intact.

[0064] Screw 19 and nut 31 are made of high-strength alloy material, which is wear-resistant and deformation-resistant. Traditional buckle or bolt fixing is prone to lateral displacement of the track due to excessive gaps, affecting assembly accuracy. The threaded drive clamping and the tightly fitting clamping plate 32 can completely limit the lateral displacement of the track and solve the problem of unstable positioning. Traditional track clamps are mostly specially designed, and one type of track requires one type of clamp, resulting in high equipment investment costs. The adjustable clamping plate 32 and adaptive structure of Embodiment 4 are compatible with multiple specifications and shapes of tracks, greatly reducing the adaptation cost and adapting to batch assembly scenarios of multiple specifications of tracks. Traditional lateral fastening requires tools such as wrenches and screwdrivers, which is inconvenient and inefficient. The rotary rod 30 of Embodiment 4 is designed to be manually adjustable without additional tools, improving the ease of operation and adapting to the needs of rapid on-site assembly. Traditional metal clamping plates 32 rigidly contact the track, which is easy to scratch or deform the track surface, affecting track performance. The elastic and wear-resistant clamping plate 32 can buffer the clamping force to achieve non-destructive fastening and solve the problem of appearance and performance damage after track assembly.

[0065] Working principle: The device first rotates the handle 9 of the rotating shaft 11, which drives the screw 7 to rotate via the worm gear 13 and worm wheel 12. Utilizing the threaded engagement between the screw 7 and the threaded tube 4, combined with the guidance of the guide rail 2 and the slider 6, the distance between the clamping frame 3 and the clamping frame 5 is precisely adjusted to match the track specifications. The worm gear 13 and worm wheel 12 are self-locking to prevent loosening. Next, the track is placed in the assembly area. The track pushes the suction cup 28 to move the plug tube 18 and piston 25 upward, expelling the air from the installation cylinder 17. The valve core 24 resets and seals to form a negative pressure. The suction cup 28 adsorbs the track for initial positioning. The locking teeth 39 and the fixing teeth 26 cooperate to prevent the plug tube 18 from falling. Finally, the rotating rod 30 of the screw 19 is rotated to push the clamping plate 32 to clamp the track laterally, forming a complete positioning process of "distance adjustment, negative pressure adsorption, and lateral fastening". To unlock, pressing the pressure plate 43 will release the lock.
