Description

Technical Field

[0001] This application relates to the field of catheter positioning technology, and specifically to a catheter polishing and positioning device. Background Technology

[0002] In fluid polishing equipment applications, traditional conduit fixing typically involves manual bolting. This method has numerous drawbacks, severely impacting production efficiency and product quality. Firstly, manual bolting is cumbersome, requiring operators to spend significant time and effort tightening and adjusting the bolts to ensure accurate conduit positioning. This not only increases labor intensity but also drastically reduces work efficiency, failing to meet the demands of modern industrial production for high-efficiency, rapid production cycles.

[0003] Manual bolt fixing makes it difficult to guarantee the accuracy of conduit positioning. During the tightening process, human error and uneven bolt tightening force can easily lead to conduit position deviation. This inaccurate positioning directly affects the fluid polishing effect, resulting in uneven conduit surface polishing, making it difficult to meet high product quality standards, increasing the defect rate, and raising production costs. Furthermore, with traditional methods, further adjustments to the conduit position after clamping are difficult to make. It often requires loosening the bolts again, repositioning, and tightening, a complex and time-consuming process. Moreover, this fixing method has poor versatility; for different models and specifications of fluid polishing equipment, it may be necessary to redesign and manufacture suitable bolt fixing structures, increasing equipment operating costs and maintenance difficulty.

[0004] Therefore, it is urgent to develop a device that can conveniently, quickly, and accurately clamp and position the conduit, facilitate further adjustment after clamping, and be directly installed on fluid polishing equipment. This is of great significance for improving the working efficiency and product quality of fluid polishing equipment. Summary of the Invention

[0005] To address the aforementioned technical problems, this application solves the issues of inconvenience, slow speed, inaccurate positioning, and difficulty in subsequent adjustments inherent in the traditional manual bolt fixing method for fluid polishing equipment.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a positioning device for conduit polishing, comprising a base, a cover plate fixedly mounted on the base, two outer control rods, an inner control rod, and a sliding rod slidably mounted on the cover plate, handles fixedly mounted on the two outer control rods, and clamping assemblies fixedly mounted on the outer control rods, the clamping assemblies comprising a telescopic rod, a spring, and a roller, the telescopic rod being fixedly connected to the outer control rods, the spring being sleeved on the telescopic rod, the two ends of the spring being fixedly connected to the telescopic rod and the outer control rod respectively, the roller being rotatably connected to the telescopic rod, and clamping assemblies also being mounted on the two inner control rods and the sliding rod.

[0007] Preferably, the inner control rod is provided with a recess at the point where it contacts the cover plate, and the recess slides on the groove of the cover plate.

[0008] Preferably, a lower horizontal connecting rod is fixedly mounted on the outer control rod, and an outer push-pull rod is rotatably mounted on the lower horizontal connecting rod. Multiple outer supports are fixedly mounted on the cover plate, and an outer limiting plate is fixedly mounted on the end of the outer support away from the cover plate. A groove is provided on the outer limiting plate, and a horizontal push rod is slidably mounted on the groove. The horizontal push rod is fixedly connected to the inner control rod, and the end of the horizontal push rod away from the inner control rod is rotatably connected to the end of the outer push-pull rod away from the lower horizontal connecting rod.

[0009] Preferably, an upper limit plate is fixedly provided at the end of the inner control rod away from the cover plate. The length of the upper limit plate is greater than the distance between the two outer control rods, and the movement of the outer control rod is restricted by the upper limit plate.

[0010] Preferably, a lower connecting shaft is fixedly installed at one end of the inner control rod near the cover plate, an inner push-pull rod is rotatably installed on the lower connecting shaft, a connecting shaft is fixedly installed on the lower sliding rod, the inner push-pull rod is rotatably connected to the connecting shaft, and the connecting shaft and the lower sliding rod are moved by the inner push-pull rod.

[0011] Preferably, the outer control rod is provided with a sliding groove, on which a vertical shaft is slidably mounted. The vertical shaft is fixedly connected to the cover plate, and a buffer spring is sleeved on the vertical shaft. The two ends of the buffer spring are fixedly connected to the cover plate and the outer control rod, respectively.

[0012] The technical solution provided in this application has the following advantages compared with the prior art:

[0013] 1. This application abandons the cumbersome traditional method of manually fixing conduits with bolts and innovatively designs a unique clamping component layout. The clamping components on the outer control rod, inner control rod, and sliding rod work together, and through ingenious structural linkage, the clamping action of the conduit can be quickly realized. The operator only needs to operate the handle on the outer control rod to quickly move all clamping components synchronously closer to or further away from the conduit, which greatly shortens the time required for conduit positioning, significantly improves work efficiency, and meets the demand for high-efficiency operation in modern industrial production.

[0014] 2. This application effectively overcomes the problem of unstable positioning of the conduit due to its own weight and unbalanced forces by combining the top and bottom clamping at both ends with the left and right clamping in the middle. This precise positioning method ensures the accuracy and stability of the conduit's position after clamping, providing a precise foundation for subsequent fluid polishing operations. During fluid polishing, a stable conduit position ensures the consistency and uniformity of the polishing effect, thereby improving product quality and reducing the defect rate.

[0015] 3. The roller configuration in this application provides flexible adjustment space for the conduit. After the conduit is clamped and fixed, the back-and-forth movement of the conduit can be easily controlled by the friction between the roller and the conduit. This allows operators to precisely adjust the installation distance of the conduit according to the specific requirements of the fluid polishing equipment, achieving accurate docking with the equipment. This convenient adjustment method enables the device to adapt to different models and specifications of fluid polishing equipment, enhancing its versatility and adaptability.

[0016] 4. This application is specifically designed to replace the conventional manual bolt fixing method in fluid polishing equipment, and is highly compatible with fluid polishing equipment in terms of structure and function. After the conduit is clamped and positioned, it can be directly installed on the fluid polishing equipment without complicated conversion or adjustment steps. This high degree of compatibility and convenient installation method reduces the difficulty and time cost in the equipment integration process, and improves the continuity and efficiency of the overall production process.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] like Figures 1 to 6 As shown, a positioning device for conduit polishing includes a base 101. A cover plate 102 is fixedly mounted on the base 101. Two outer control rods 103, an inner control rod 111, and a sliding rod 116 are slidably mounted on the cover plate 102. Handles 104 are fixedly mounted on the two outer control rods 103. Clamping assemblies are fixedly mounted on the outer control rods 103. The clamping assemblies include a telescopic rod 105, a spring 106, and a roller 107. The telescopic rod 105 is fixedly connected to the outer control rods 103. The spring 106 is sleeved on the telescopic rod 105. The two ends of the spring 106 are fixedly connected to the telescopic rod 105 and the outer control rod 103, respectively. The roller 107 is rotatably connected to the telescopic rod 105. Clamping assemblies are also provided on the two inner control rods 111 and the sliding rod 116.

[0027] Specifically, the clamping components on the outer control rod 103 and the sliding rod 116 are symmetrically arranged, and the clamping components on the two inner control rods 111 are located in the middle of the two outer control rods 103. That is, during positioning, the two ends of the tube are clamped vertically, and the middle is clamped horizontally. The two sets of vertical clamps prevent the weight of the unclamped part of the tube from affecting the clamping effect. If the horizontal clamping components are located on the outside, the weight of the tube itself will cause the tube to slide down and detach from the clamping components on the left and right sides, losing the positioning effect. If only one set of vertical clamping components is set, the tube may tilt due to insufficient clamping force. Therefore, two sets of vertical clamping components are required, with the horizontal clamping components located in the middle. This method ensures the positioning of the tube, stabilizes the position of the tube, and facilitates docking with the tube port during subsequent fluid polishing, thus ensuring the stability of the tube interface axis and facilitating connection.

[0028] like Figure 5 and Figure 6 As shown, a recess is provided where the inner control rod 111 contacts the cover plate 102, and the recess slides on the groove of the cover plate 102.

[0029] Specifically, the upper part of the two inner control rods 111 is larger than the lower recess. Through the difference in size, the upper part of the inner control rod 111 slides on the upper surface of the cover plate 102, while the recess of the inner control rod 111 slides in the groove of the cover plate 102. The difference in size also forms a support for the inner control rod 111.

[0030] like Figures 3 to 6 As shown, a lower horizontal connecting rod 119 is fixedly installed on the outer control rod 103, and an outer push-pull rod 120 is rotatably installed on the lower horizontal connecting rod 119. Multiple outer brackets 108 are fixedly installed on the cover plate 102. An outer limiting plate 109 is fixedly installed at the end of the outer bracket 108 away from the cover plate 102. A groove is provided on the outer limiting plate 109, and a horizontal push rod 110 is slidably installed on the groove. The horizontal push rod 110 is fixedly connected to the inner control rod 111. The end of the horizontal push rod 110 away from the inner control rod 111 is also rotatably connected to the end of the outer push-pull rod 120 away from the lower horizontal connecting rod 119.

[0031] Specifically, such as Figure 6 As shown, the grooves of the two outer limiting plates 109 cooperate with each other to limit the two sides of the horizontal push rod 110, forming a sliding groove for the movement of the inner control rod 111.

[0032] In use, the outer control lever 103 moves downward, and the outer control lever 103 pulls the lower end of the outer push rod 120 downward through the lower horizontal connecting rod 119. Then, the upper end of the outer push rod 120 pulls the left end of the horizontal push rod 110. Under the restriction of the grooves of the two outer limit plates 109, the outer push rod 120 slides on the outer limit plate 109 towards the inner control lever 111, that is, towards the direction of the conduit. Thus, the right end of the horizontal push rod 110 pushes the inner control lever 111 to slide on the cover plate 102. Thus, the inner control lever 111 pushes the clamping component set on it to approach and contact the conduit. The inner control lever 111 on the other side works in the same way as the clamping component, but moves in the opposite direction. Thus, the clamping components on both sides work together to clamp and limit the conduit on both sides.

[0033] After clamping, if it is necessary to adjust the front and rear distance, the conduit can be controlled to slide on the rollers 107 of the two clamping components. The rollers 107 are rotated and the friction between the conduit and the rollers 107 drives the rollers 107 to rotate, thereby facilitating the movement of the conduit.

[0034] like Figure 1 , Figure 3 and Figure 5 As shown, an upper limit plate 113 is fixedly provided at the end of the inner control rod 111 away from the cover plate 102. The length of the upper limit plate 113 is greater than the distance between the two outer control rods 103. The movement of the outer control rods 103 is restricted by the upper limit plate 113.

[0035] Specifically, when the outer control lever 103 moves downward, the contact between the outer control lever 103 and the upper limit plate 113 blocks and restricts the movement of the outer control lever 103, preventing the outer control lever 103 from moving excessively and causing the clamping assembly on the outer control lever 103 to apply excessive pressure to the conduit, thereby damaging the conduit.

[0036] like Figure 3 , Figure 5 and Figure 6 As shown, a lower connecting shaft 112 is fixedly installed at one end of the inner control rod 111 near the cover plate 102. An inner push-pull rod 114 is rotatably installed on the lower connecting shaft 112. A connecting shaft 115 is fixedly installed on the lower sliding rod 116. The inner push-pull rod 114 is rotatably connected to the connecting shaft 115. The inner push-pull rod 114 pushes the connecting shaft 115 and the lower sliding rod 116 to move.

[0037] Specifically, when the inner control rod 111 moves on the cover plate 102 toward the direction of the conduit, the lower end of the inner control rod 111 pushes the left end of the inner push-pull rod 114 through the lower connecting shaft 112. Because the horizontal height of the lower connecting shaft 112 is lower than the horizontal height of the connecting shaft 115, the right end of the inner push-pull rod 114 pushes the connecting shaft 115, thereby pushing the sliding rod 116 to slide vertically upward on the cover plate 102. This causes the clamping component on the sliding rod 116 to approach and contact the conduit, cooperating with the clamping component on the outer control rod 103 to clamp and restrict the movement of the conduit.

[0038] like Figures 3 to 6 As shown, the outer control rod 103 is provided with a sliding groove, on which a vertical shaft 117 is slidably disposed. The vertical shaft 117 is fixedly connected to the cover plate 102. A buffer spring 118 is sleeved on the vertical shaft 117, and the two ends of the buffer spring 118 are fixedly connected to the cover plate 102 and the outer control rod 103, respectively.

[0039] Specifically, when the external control lever 103 moves downward, the lower end of the external control lever 103 slides downward on the vertical shaft 117 and pulls the buffer spring 118 on the vertical shaft 117. Subsequently, the external control lever 103 is reset by the elastic force of the buffer spring 118.

[0040] Working principle: In the initial state, the elastic force of the buffer springs 118 on the four vertical shafts 117 controls the position of the outer control rod 103, placing it at its lowest point. This positions the clamping components on the outer control rod 103 closest to the positioning space axis. Furthermore, the push of the outer push-pull rod 120 and the inner push-pull rod 114 moves the clamping components on the inner control rod 111 and the sliding rod 116 to their extreme positions, meaning the diameter of the conduit clamped by the six clamping components is minimized. If conduit placement is required, the operator can manually... The handle 104 on the external control lever 103 moves upward, thereby pulling the two external control levers 103 to slide upward on the cover plate 102. This causes the lower ends of the external control levers 103 to slide upward on the vertical shaft 117, compressing the buffer spring 118. The external control levers 103, through the lower horizontal connecting rod 119, push the external push rod 120. The external push rod 120 pushes the horizontal push rod 110 on the outer limit plate 109 in a direction away from the inner control lever 111, thereby causing the inner control lever 111 and the clamping assembly to move away from the center position, i.e., the guide tube. The installation position; when the inner control rod 111 moves, it pulls the connecting shaft 115 and the sliding rod 116 downward through the lower connecting shaft 112 and the inner push-pull rod 114, thereby causing the clamping components on the sliding rod 116 to move away from the center position, ultimately causing the 6 clamping components to move away from each other, increasing the diameter of the conduit that can be placed at the center position. Then, the operator puts in the conduit to be processed, and then releases the handle 104. Under the action of the four buffer springs 118, the outer control rod 103 moves downward on the cover plate 102, and then pushes outward. Pull rod 120 and inner push-pull rod 114 control the movement of the other four clamping components, so that the six clamping components move closer together and contact the conduit. Through the elastic force of buffer spring 118 and the elastic force of spring 106 of the clamping component itself, the roller 107 and the conduit can achieve a tight connection and maintain the state. After clamping, the operator controls the conduit to move back and forth on the roller 107 to control the installation distance of the conduit, that is, the connection position with the fluid polishing table, so as to facilitate the subsequent connection of the conduit and the positioning device of this application to the fluid polishing machine.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
