Description

Technical Field

[0001] This application relates to the field of grinding equipment, specifically to a fine tube chamfering grinding device. Background Technology

[0002] In the field of precision machining, especially in the manufacturing of medical devices, optical instruments and microfluidic equipment, the chamfering of the ends of thin tubular workpieces is a key process that affects the sealing performance and assembly accuracy of the product.

[0003] Existing chamfering equipment generally employs a multi-axis linkage mechanical structure, using gear sets to drive the tool feed. The transmission mechanism requires independent angle adjustment modules and depth control units, leading to increased equipment size and poor applicability in space-constrained environments such as cleanrooms or minimally invasive surgical instrument production lines. The tube clamps use a fixed V-groove structure, supporting only a tube diameter tolerance range of ±0.5mm, necessitating frequent replacement of clamping components when dealing with a wide range of medical catheter specifications. Adjusting chamfering parameters requires changing tool holders with different angles and distances, with a single angle adjustment taking up to 20 minutes, severely impacting the pace of multi-variety, small-batch production. Furthermore, existing equipment lacks a dynamic adjustment mechanism for grinding parameters, resulting in a fixed grinding roughness; if adjustments to the grinding roughness are needed mid-process, the equipment must be replaced. Summary of the Invention

[0012] The pressure plate is used to fix the abrasive paper on the adjustment frame.

[0013] Specifically, the pressure plate is connected to the adjustment frame by a spring clip or bolt fixing structure.

[0014] Specifically, the drive module includes a hollow motor, the output shaft of which has a hollow structure, and the hollow structure is used to allow the other end of the thin tube to pass through.

[0026] like Figure 1 As shown, this embodiment provides a fine tube chamfering and grinding device, including: a mounting plate 1, a clamping module 2, a slider 3, a grinding module 4, and a driving module 5.

[0027] Mounting plate 1 includes a base plate 11 and a side plate 12, with the base plate 11 serving as the base of the entire device. The side plate 12, clamping module 2, slider 3, grinding module 4, and drive module 5 are disposed above the top surface of the base plate 11. The side plate 12 is vertically mounted on the base plate 11, and the connection between the side plate 12 and the base plate 11 can be secured by welding or bolts to ensure its rigidity.

[0028] The clamping module 2 is located on one side of the side plate 12. The clamping module 2 is used to clamp the thin tube 6 and fix the thin tube 6 horizontally at a certain height position, exposing the end face of the thin tube 6 that needs to be ground. The clamping module 2 drives the thin tube 6 to rotate together along the cylindrical thin tube 6 axis.

[0029] The slider 3 is positioned above the base plate 11, which may be equipped with a guide rail, a slide groove, or a lead screw mechanism. The slider 3 can reciprocate along the guide rail, slide groove, or lead screw mechanism on the base plate 11 to adjust the relative position of the grinding module 4 on the slider 3 to the end face of the thin tube 6. The movement of the slider 3 can be manually adjusted or automatically fed by motor control.

[0030] The grinding module 4 is movably mounted on the slider 3. The grinding module 4 and slider 3 are detachable, allowing for the replacement of grinding modules 4 with different roughnesses to be mounted on the slider 3, adapting to the chamfering grinding of thin tubes with varying roughness requirements. The grinding module 4 can change its relative angle to the end face of the thin tube 6, adapting to the chamfering grinding of thin tubes with different chamfering angle requirements. Furthermore, the grinding module 4 reciprocates together with the slider 3, changing its position relative to the end face of the thin tube 6, adapting to the chamfering grinding of thin tubes with different chamfering depth requirements. The grinding module 4 contacts the end face of the thin tube 6 to perform grinding processing on the end face of the thin tube 6, forming a chamfer.

[0031] The drive module 5 is mounted on the side plate 12 away from the base plate 11 and fixes the clamping module 2 thereon. The drive module 5 is used to drive the clamping module 2 to rotate the thin tube 6. The drive module 5 is a variable frequency motor that supports speed adjustment to adapt to thin tubes of different materials, such as metal or plastic.

[0032] Fix the mounting plate 1 on the worktable, ensuring that the base plate 11 is horizontal and the side plate 12 is vertical. Install the clamping module 2 on the side of the side plate 12 and connect the clamping module 2 to the drive module 5. Then install the slider 3 on the base plate 11 and install the grinding module 4 corresponding to the required roughness on the slider 3.

[0033] Move slider 3 away from the side plate. Slider 3 will move grinding module 4 away from the side plate 12 until there is enough space. Slider 3 and grinding module 4 will not affect the installation of the thin tube.

[0034] Insert the thin tube 6 into the clamping module 2, which keeps the thin tube 6 stable on a certain horizontal surface. Adjust the position and angle of the grinding module 4 to ensure that the contact angle and position between the grinding module 4 and the end face of the thin tube are appropriate, ensuring the grinding effect and guaranteeing its angle and depth. First, adjust the angle of the grinding module 4 to ensure that it meets the chamfer angle requirements, and then adjust the position of the slider 3 to ensure that it meets the chamfer depth requirements.

[0035] Start the drive module 5 to make the clamping module 2 drive the thin tube to rotate and start grinding to obtain the ideal chamfer effect.

[0036] After grinding is complete, stop drive module 5, release clamping module 2, and remove the thin tube 6. Check the chamfering effect of the end face of the thin tube 6. If it does not meet the requirements, repeat the above steps for adjustment and grinding.

[0037] In this embodiment, the clamping module is directly fixed to the drive module. This design not only reduces the number of parts but also lowers errors and wear in mechanical transmission. Through the precise clamping of the clamping module and the stable drive of the drive module, high-precision chamfering grinding can be achieved. Furthermore, the clamping module is suitable for clamping various sizes of thin tubes. Depending on the actual situation, the contact angle between the grinding module and the end face of the thin tube can be adjusted to meet the requirements of different chamfer angles; the roughness of the grinding module can be adjusted to meet the requirements of different grinding roughnesses; and the position of the slider can be adjusted to meet the requirements of different chamfer depths. This achieves agile parameter control, meeting the chamfer angle, depth, and roughness requirements of thin tubes of different sizes without the need to replace individual modules.

[0038] In one embodiment, a positioning groove 111 is provided on the base plate 11, and the slider 3 can slide within the positioning groove 111. The friction between the contact surface of the positioning groove 111 and the slider 3 is small, and when the slider 3 slides to the preset position, the slider 3 is positioned and fixed in a timely manner.

[0039] The positioning groove 111 provides a precise guide path for the movement of the slider 3, ensuring that the slider 3 always maintains a straight line during the movement, thereby ensuring that the contact position between the grinding module 4 and the thin tube 6 is accurate and improving the grinding accuracy.

[0040] The cooperation between the positioning groove 111 and the slider 3 can effectively limit the shaking of the slider 3, making it more stable during movement and avoiding uneven grinding effect caused by the instability of the slider 3.

[0041] The relative position of the grinding module 4 and the thin tube 6 can be easily adjusted by the positioning groove 111 to accommodate thin tubes of different diameters and lengths, thus improving the versatility and flexibility of the device.

[0042] The design of the positioning groove 111 makes the structure of the entire device more compact, reduces the need for additional positioning devices or complex mechanical structures, and lowers the complexity and cost of the device.

[0043] The guiding function of the positioning groove 111 makes the movement of the slider smoother, reduces adjustment time, and improves the working efficiency of the grinding device.

[0044] In one embodiment, the slider 3 can be driven by a sliding motor, and a slider displacement command can be set. The sliding motor drives the slider 3 to slide to a preset position according to the command. In another embodiment, the position of the slider 3 can be adjusted manually.

[0045] In one embodiment, there is an inclination angle between the groove surface of the positioning groove 111 and the horizontal plane where the side plate 12 is located. The bottom surface of the positioning groove 111 is inclined relative to the side plate 12. The inclined bottom surface of the positioning groove 111 allows the slider 3 to directly form a certain angle with the axis of the thin tube 6, thereby optimizing the contact angle between the grinding module 4 and the end face of the thin tube 6. The contact angle between the grinding module 4 and the end face of the thin tube 6 is coarsely adjusted by moving the slider directly on the positioning groove 111. Without changing the grinding module, the contact angle is roughly adjusted according to the chamfer angle required for the end face of the thin tube. When the slider 3 moves to the preset position, the grinding module contacts the end face of the thin tube at an inclination, and then the grinding module 4 is adjusted more finely to meet its chamfer angle requirements.

[0046] In one embodiment, the grinding module 4 includes an adjustment frame 41 and a grinding unit 42. The adjustment frame 41 is mounted on the slider 3, and the grinding unit 42 is mounted on the adjustment frame 41. The adjustment frame 41 can be adjusted at an angle relative to the end face of the thin tube, and the grinding unit 42 forms a corresponding contact angle with the end face of the thin tube together with the adjustment frame 41.

[0047] In one embodiment, the adjustment frame 41 includes three panels, two of which are respectively connected to the two sides of the slider, and the third panel connects the two panels to form a plane that can fix the grinding unit 42. The adjustment frame 41 moves circumferentially around the connection point of the two panels connected to the slider, changing the angle of the plane that fixes the grinding unit 42.

[0048] In one embodiment, the grinding unit 42 includes a pressure plate 421 and grinding paper 422. The grinding paper 422 is used to contact the end face of the thin tube 6 to grind the thin tube 6. The pressure plate 421 is used to fix the grinding paper 422 on the adjusting frame 41. The grinding paper 422 can be replaced by moving the pressure plate 421, and different roughness grinding papers 422 can be replaced according to actual needs. After replacing the grinding paper 422, the pressure plate 421 is applied to the grinding paper 422 to fix the grinding paper on the adjusting frame 41. The requirement for different grinding roughness of the chamfer can be achieved simply by replacing the grinding paper 422 with different roughness grinding papers.

[0049] In one embodiment, the drive module 5 includes a hollow motor with a hollow output shaft. This hollow structure allows the other end of the thin tube to pass through, eliminating the need for belts, gears, and other transmission structures required in traditional motors, thus simplifying the mechanical design. Furthermore, the reduced number of transmission components simplifies the maintenance of the hollow motor. Frequent inspection and replacement of belts or gears are unnecessary, reducing equipment maintenance costs and downtime.

[0050] This design not only reduces the number of parts but also lowers errors and wear in mechanical transmission. The compact design of the hollow motor significantly reduces the overall size of the equipment, making it more compact, easier to install and operate, and especially suitable for working environments with limited space.

[0051] Because the hollow motor can directly drive the thin tube 6 to rotate, vibration and shaking in the mechanical transmission are reduced, thus reducing processing errors caused by vibration. It avoids problems such as sliding, slippage, or wear that may occur in traditional transmission structures, thereby improving the precision of the grinding process.

[0052] In one embodiment, the clamping module 2 includes a three-jaw chuck, which is used to clamp thin tubes of different diameters and is suitable for thin tubes of different materials.

[0053] The three-jaw chuck can automatically adjust its clamping position according to the diameter of the thin tube, and can clamp thin tubes of different diameters without changing the clamp or making complicated adjustments, which greatly improves the versatility of the device.

[0054] Whether it's a metal tube, plastic tube, or composite material tube, the three-jaw chuck can provide stable clamping force and is suitable for thin tubes of various materials.

[0055] The three jaws of the three-jaw chuck are evenly distributed around the thin tube, ensuring uniform clamping force and preventing deformation of the tube due to excessive local clamping force. The three-jaw chuck can automatically center, ensuring that the center of the thin tube coincides with the rotation center of the clamping module, thereby improving the accuracy and stability during grinding.

[0056] In one embodiment, a connector 7 is provided between the clamping module 2 and the drive module 5, connecting the clamping module 2 and the drive module 5, thus integrating the clamping module 2 and the drive module 5. This integration reduces errors and vibrations during the transmission process, ensuring the rotational accuracy and stability of the clamping module 2. Furthermore, the integrated design reduces the number of intermediate transmission components, simplifying the overall structure of the device.

[0057] The connector 7 is designed to be adjustable for thin tubes of different diameters and lengths, allowing the clamping and drive modules to better adapt to various processing needs. This versatile design improves the flexibility of the equipment and reduces the additional costs associated with changing fixtures or adjusting the equipment.

[0058] In one embodiment, the slider is connected to a sliding motor, which drives the slider to move and adjust the contact position between the grinding module and the thin tube. The sliding motor enables precise displacement control, allowing the slider to move in minute steps to accurately adjust the contact position between the grinding module and the thin tube. Furthermore, the motor-driven operation ensures consistent precision and position during each grinding cycle, reducing human error and improving grinding quality consistency. The automated control of the sliding motor reduces manual intervention; operators only need to set parameters, and the motor automatically adjusts the grinding position. This not only improves grinding efficiency but also reduces downtime caused by manual adjustments. The slider's movement speed can be adjusted as needed, enabling rapid access to the target position and further enhancing grinding efficiency.

[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
