Description

Technical Field

[0001] This application relates to the field of pipe processing technology, and in particular to a device for grinding the outer surface of tubular workpieces. Background Technology

[0002] Currently, the grinding of the outer surface of tubular workpieces is a key process to ensure their quality and performance. Traditional grinding methods for the outer surface of tubular workpieces mostly use manual hand-held grinding tools or rely on simple fixing devices in conjunction with single-axis grinding equipment, which have many shortcomings.

[0003] When operating manually, the workpiece is not fixed securely, and the grinding force and angle are difficult to control precisely. This not only results in low grinding efficiency but also easily causes problems such as uneven grinding of the outer surface and poor precision, which need to be improved. Utility Model Content

[0004] In order to improve the grinding efficiency of tubular workpieces, this application provides a grinding device for the outer surface of tubular workpieces.

[0005] This application provides a grinding device for the outer surface of a tubular workpiece, which adopts the following technical solution:

[0006] A grinding device for the outer surface of a tubular workpiece includes a base, on which a first support, a second support, and a grinding mechanism for grinding the tubular workpiece are provided. The grinding mechanism is slidably mounted on the base. Both the first and second supports are provided with support mechanisms for supporting the tubular workpiece, and the second support is provided with a driving mechanism for driving the support mechanisms to rotate.

[0007] By adopting the above technical solution, the two ends of the tubular workpiece are fixed by the support mechanism on the first and second brackets. The support mechanism is driven by the drive mechanism to rotate the tubular workpiece. The operator manually adjusts the position of the grinding mechanism on the base so that the grinding mechanism can continuously grind the outer surface of the tubular workpiece. Compared with the traditional manual grinding method, the grinding efficiency of the tubular workpiece is improved.

[0008] Preferably, the support mechanism includes a rotating roller rotatably connected to a second bracket, a support block coaxially fixed to the rotating roller, and an adjusting rod for stabilizing the tubular workpiece. The rotating roller is connected to a drive mechanism. The adjusting rods are arranged in a circumferential array on the support block. The support block is provided with a drive member for synchronously driving the adjusting rods to extend and retract radially along the support block. One end of any adjusting rod is connected to the drive member, and the other end abuts against the inner wall of the tubular workpiece. A connecting spring is sleeved on any adjusting rod. One end of any connecting spring is connected to the outer wall of the support block, and the other end is connected to the end of the adjusting rod.

[0009] By adopting the above technical solution, the adjusting rods are arranged in a circumferential array and synchronously extended and retracted by the driving component, so that the adjusting rods can be adaptively adjusted according to the inner diameter of the tubular workpiece, thereby achieving stable support for tubular workpieces of different specifications. The setting of the connecting spring enhances the stability and buffering effect of the support, avoiding damage to the inner wall of the tubular workpiece. At the same time, the driving mechanism drives the rotating roller to rotate, thereby driving the support block and the tubular workpiece to rotate, so as to facilitate subsequent grinding operations.

[0010] This improves the versatility and applicability of the grinding device, ensuring that tubular workpieces of different inner diameters remain stable during the grinding process and improving the grinding quality.

[0011] Preferably, the driving component includes a frustum block and a driving column. The frustum block is disposed inside the support block. The driving column passes through a rotating roller along its axial direction and is coaxially fixed with the frustum block. The driving column is threadedly connected inside the rotating roller. The end of any of the adjusting rods away from the tubular workpiece forms an abutment fit with the side wall of the frustum block.

[0012] By adopting the above technical solution, during use, the operator drives the drive column to move inside the rotating roller by turning the handwheel, thereby driving the frustum block to move inside the support block. Since the side wall of the frustum block abuts against the end of the adjusting rod, the movement of the frustum block can drive the adjusting rod to extend and retract radially along the support block, effectively realizing precise control of the extension and retraction of the adjusting rod and providing stable support for tubular workpieces with different inner diameters.

[0013] Preferably, the drive mechanism includes a first motor, a driving gear, a driven gear, and a synchronous toothed belt. The first motor is mounted on a second bracket, and the output shaft of the first motor is coaxially fixed with the driving gear. The synchronous toothed belt is synchronously wound around the driving gear and the driven gear, and the driven gear is coaxially fixed with the rotating roller.

[0014] By adopting the above technical solution, the first motor drives the active gear to rotate, and the active gear drives the driven gear to rotate through the synchronous toothed belt. The driven gear then drives the rotating roller connected to it to rotate, thereby ensuring that the rotation speed of the tubular workpiece is uniform during the grinding process, and thus ensuring the uniformity and accuracy of the outer surface grinding.

[0015] Preferably, the base is provided with a slide rail for sliding cooperation with the first bracket, and the first bracket is threaded with a locking bolt for sliding and locking the first bracket, the locking bolt passing through the first bracket and abutting against the base for limitation.

[0016] By adopting the above technical solution, the first bracket and the slide rail form a sliding fit, and the first bracket is slidably locked by the locking bolt, so that the position of the first bracket can be adjusted according to the length of the tubular workpiece, thereby adapting to tubular workpieces of different lengths and meeting diverse processing needs; and the locking bolt can ensure that the first bracket remains stable in the adjusted position, ensuring the stability of the tubular workpiece during the grinding process.

[0017] Preferably, the grinding mechanism includes a sliding frame, a grinding wheel mounted on the sliding frame, a second motor for driving the grinding wheel to rotate, and a pulley mounted at the bottom of the sliding frame. The second motor is mounted on the sliding frame, and the output shaft of the second motor is coaxially fixed with the grinding wheel. The base is provided with a sliding rod for sliding cooperation with the pulley, and the pulley is rotatably connected to the sliding rod.

[0018] By adopting the above technical solution, the sliding engagement between the pulley and the slide rod allows the operator to easily adjust the position between the grinding wheel and the tubular workpiece. At the same time, the rotational engagement between the pulley and the slide rod allows the operator to flexibly adjust the position and angle of the sliding frame, thereby adjusting the position and angle between the grinding wheel and the tubular workpiece.

[0019] Preferably, the base is provided with an anti-tipping block to prevent the sliding frame from tipping over.

[0020] By adopting the above technical solution and utilizing the anti-tipping block on the base, the sliding frame can be effectively prevented from tipping over during the grinding process, ensuring the safety and stability of the grinding device.

[0021] Preferably, the sliding frame is provided with a handle to facilitate the movement of the sliding frame by the staff.

[0022] By adopting the above technical solution and utilizing the handle on the sliding frame, it is convenient for workers to manually move the sliding frame and quickly adjust the position of the grinding wheel, which is more convenient and flexible than other adjustment methods.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The two ends of the tubular workpiece are fixed by the support mechanism on the first and second brackets. The support mechanism is driven by the drive mechanism to rotate the tubular workpiece. The operator manually adjusts the position of the grinding mechanism on the base so that the grinding mechanism can continuously grind the outer surface of the tubular workpiece. Compared with the traditional manual grinding method, the grinding efficiency of the tubular workpiece is improved.

[0025] 2. By using a circumferential array of adjusting rods and synchronously extending and retracting them via a drive mechanism, the adjusting rods can adaptively adjust according to the inner diameter of the tubular workpiece, achieving stable support for tubular workpieces of different specifications. The connecting springs enhance the stability and buffering effect of the support, preventing damage to the inner wall of the tubular workpiece. At the same time, the drive mechanism drives the rotating roller to rotate, thereby causing the support block and the tubular workpiece to rotate, so as to facilitate subsequent grinding operations.

[0026] 3. By utilizing the sliding engagement of the pulley and the slide rod, the operator can easily adjust the position between the grinding wheel and the tubular workpiece. At the same time, by utilizing the rotational engagement of the pulley and the slide rod, the operator can flexibly adjust the position and angle of the sliding frame, thereby adjusting the position and angle between the grinding wheel and the tubular workpiece.

[0034] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0035] This application discloses a device for grinding the outer surface of a tubular workpiece.

[0036] Reference Figure 1 A grinding device for the outer surface of a tubular workpiece includes a base 1, which is a rectangular steel plate. A first support 2, a second support 3, and a grinding mechanism 4 for grinding the tubular workpiece are provided on the base 1. The second support 3 is welded and fixed to the base 1. The first support 2 and the second support 3 are at the same height and are both provided with a support mechanism 5 for supporting the tubular workpiece, so that the two ends of the tubular workpiece are respectively fixed on the support mechanism 5.

[0037] Reference Figure 1 and Figure 2 A slide rail 11 is installed on the surface of the base 1 along its length. The first bracket 2 and the slide rail 11 form a sliding fit. A locking bolt 21 is threaded on the first bracket 2. The locking bolt 21 passes through the first bracket 2 and abuts against the base 1 to limit its position, so that the position of the first bracket 2 can be adjusted according to the length of the tubular workpiece, thereby adapting to tubular workpieces of different lengths. At the same time, the sliding adjustment and locking of the first bracket 2 can be achieved by the locking bolt 21, which can meet diverse processing needs.

[0038] Reference Figure 3 and Figure 4 The second bracket 3 is equipped with a drive mechanism 6 for driving the support mechanism 5 to rotate. Since the two support mechanisms 5 have the same structure and connection method, we will now take one of the support mechanisms 5 as an example for explanation.

[0039] Reference Figure 3 and Figure 4 The support mechanism 5 includes a rotating roller 51, a support block 52, and an adjusting rod 53. The support block 52 is cylindrical and fits into the tubular workpiece. The rotating roller 51 is horizontally mounted on the top of the second bracket 3 via a bearing and fits into the second bracket 3. One end of the rotating roller 51 is coaxially fixed with the support block 52, and the other end is connected to the drive mechanism 6. The support block 52 has four guide grooves arranged in a radial circumferential array. The adjusting rod 53 is set in the position and number of the guide grooves, and any adjusting rod 53 is slidably set in the corresponding guide groove.

[0040] Reference Figure 3 and Figure 4 A connecting spring 54 is fitted on any adjusting rod 53. One end of the connecting spring 54 is glued to the outer wall of the support block 52, and the other end is glued to the end of the adjusting rod 53. The connecting spring 54 enhances the stability and buffering effect of the support, and avoids damage to the inner wall of the tubular workpiece.

[0041] Reference Figure 3 and Figure 4 The support block 52 is provided with a driving component 55 for synchronously driving four adjusting rods 53 to extend and retract radially along the support block 52. The driving component 55 includes a frustum block 551, a driving column 552 and a handwheel 553. The frustum block 551 is slidably disposed inside the support block 52. The driving column 552 passes through the interior of the rotating roller 51 along its axial direction and is coaxially fixed with the frustum block 551. The driving column 552 is threadedly connected inside the rotating roller 51. The handwheel 553 is coaxially fixed with the driving column 552. One end of any adjusting rod 53 forms an abutment with the side wall of the frustum block 551 through an arc surface, and the other end abuts against the inner wall of the tubular workpiece.

[0042] Reference Figure 3 and Figure 4 The operator rotates the handwheel 553 to move the drive column 552, which in turn drives the frustum block 551 to move axially inside the support block 52. Since the adjusting rod 53 forms an abutment with the side wall of the frustum block 551 through the arc surface, the movement driven by the frustum block 551 can drive the adjusting rod 53 to extend and retract radially along the support block 52, effectively realizing precise control of the extension and retraction of the adjusting rod 53 and providing stable support for tubular workpieces with different inner diameters.

[0043] Reference Figure 3 and Figure 4 The drive mechanism 6 includes a first motor 61, a drive gear 62, a driven gear 63, and a synchronous toothed belt 64. The first motor 61 is mounted on the second bracket 3. The output shaft of the first motor 61 is coaxially fixed with the drive gear 62. The synchronous toothed belt 64 is synchronously wound around the drive gear 62 and the driven gear 63. The driven gear 63 is coaxially fixed with the rotating roller 51.

[0044] Reference Figure 3 and Figure 4 When the first motor 61 starts, the driving gear 62 drives the driven gear 63 to rotate through the synchronous toothed belt 64. The driven gear 63 drives the rotating roller 51, the support block 52 and the drive column 552 to rotate synchronously, ensuring that the speed of the tubular workpiece is uniform during the grinding process, thereby ensuring the uniformity and accuracy of the outer surface grinding.

[0045] Reference Figure 5 and Figure 6A slide rod 12 is installed on the base 1, and the slide rod 12 is set parallel to the slide rail 11. The grinding mechanism 4 is slidably set on the base 1. The grinding mechanism 4 includes a sliding frame 41, a grinding wheel 42, a second motor 43 and a pulley 44. The grinding wheel 42 and the second motor 43 are both installed on the top of the sliding frame 41. The grinding wheel 42 is set on the sliding frame 41, and the output shaft of the second motor 43 is coaxially fixed with the grinding wheel 42 through a coupling. The second motor 43 drives the grinding wheel 42 to rotate at high speed, providing stable grinding power.

[0046] Reference Figure 5 and Figure 6 The pulley 44 is rotatably connected to the bottom of the sliding frame 41, and the sliding frame 41 is slidably mounted on the slide rod 12 through the pulley 44. The pulley 44 and the slide rod 12 form a rotatable connection. This design allows the operator to flexibly adjust the position and angle of the sliding frame 41, thereby adjusting the position and angle between the grinding wheel 42 and the tubular workpiece, realizing all-round and multi-angle grinding of the outer surface of the tubular workpiece, and improving the accuracy and efficiency of grinding.

[0047] Reference Figure 5 and Figure 6 An anti-tipping block 13 is welded onto the base 1. The side wall of the anti-tipping block 13 abuts against the side wall of the slide rod 12, thereby effectively preventing the sliding frame 41 from tipping over during the grinding process. This ensures the safety and stability of the grinding device, avoids equipment damage or impact on grinding quality due to the sliding frame 41 tipping over, and also reduces safety hazards, providing a safer working environment for operators.

[0048] Reference Figure 5 and Figure 6 The sliding frame 41 is welded with a handle 411, which makes it easy for the staff to move the position and tilt angle of the sliding frame 41. It is convenient for the staff to manually move the sliding frame 41 to quickly adjust the position of the grinding wheel 42. Compared with other adjustment methods, it is more convenient and flexible. It can be finely adjusted at any time according to the actual grinding needs, which improves the convenience of operation and work efficiency and reduces the labor intensity of the operators.

[0049] The implementation principle of this application embodiment is as follows: In actual operation, the operator first loosens the locking bolt 21 on the first bracket 2, slides the first bracket 2 along the slide rail 11 to a position that matches the length of the workpiece, and then places the two ends of the tubular workpiece to be processed onto the support blocks 52 of the first bracket 2 and the second bracket 3 respectively. After fine-tuning the position of the first bracket 2, it is locked by the locking bolt 21. Then, the handwheel 553 is turned to drive the drive column 552 to move, thereby the drive column 552 drives the frustum block 551 to move in and out. The frustum block 551 then drives the four adjusting rods 53 to retract radially until the ends of the four adjusting rods 53 are pressed against the inner wall of the tubular workpiece, thus completing the adaptive clamping.

[0050] The first motor 61 and the second motor 43 are started respectively. At this time, the workpiece rotates at a constant speed and the grinding wheel 42 rotates at high speed. Then, the operator holds the handle 411 and pushes the sliding frame 41 to move along the slide rod 12. At the same time, the contact angle between the grinding wheel 42 and the workpiece can be adjusted around the axis of the slide rod 12 to achieve all-round grinding of the outer surface of the tubular workpiece. Meanwhile, the anti-tipping block 13 is used to limit the tilt angle of the sliding frame 41 to ensure the stability of the grinding process and improve the grinding efficiency of the tubular workpiece.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
