Description

Technical Field

[0001] The present invention relates to the technical field of machine tool plug strip processing, and in particular to a machine tool guide rail plug strip processing device and method thereof. Background Art

[0002] A machine tool guide rail plug strip is a mechanical part used to adjust and compensate for the clearance or wear of a machine tool guide rail. It is usually installed between the mating surfaces of the machine tool guide rail to ensure the accuracy, stability and service life of the guide rail. During long-term use, the contact surface between the plug strip and the dovetail groove of the equipment will wear. If the wear clearance of the plug strip is too large or too small, the machine tool will vibrate or get stuck during operation. Therefore, the plug strip needs to be polished regularly.

[0003] The purpose of polishing the plug strip is to eliminate scratches and burrs, and restore flatness (usually the flatness is required to be ≤ 0.03 mm) and roughness (Ra ≤ 1.6 μm). The existing polishing methods for plug strips are mainly divided into angle grinder polishing and CNC grinding machine polishing. Among them, the angle grinder can be operated manually on the machine tool site, but the polishing accuracy of the plug strip depends on the experience of the operator, which is likely to cause uneven surface or over-polishing, resulting in poor adaptability of the plug strip. Moreover, when the number of plug strips to be polished is large, the manual polishing efficiency is low, and it is difficult to ensure the consistency of the polishing quality during batch polishing; while the CNC grinding machine polishing can achieve high-precision and high-efficiency polishing, but since the CNC grinding machine and the machine tool equipment are processing equipment for different products, the plug strip needs to be sent to a special polishing processing factory after being removed from the machine tool. The machine tool cannot operate normally after removing the plug strip, so the plug strip will cause the machine tool equipment to stop for a long time during the polishing period, thus reducing the product production efficiency of the machine tool equipment. Summary of the Invention

[0004] In view of the problem that it is not convenient to perform rapid standardized polishing of the plug strip on the machine tool equipment site in the prior art problems, a machine tool guide rail plug strip processing device is proposed.

[0005] Its purpose is: the polishing roller rotates by itself and follows the rotation of the rotating frame. When the polishing roller is located at the lower side, it moves horizontally to perform horizontal polishing on the polishing surface of the plug strip. Multiple polishing rollers are sequentially in contact with the polishing surface of the plug strip to complete step-by-step standardized polishing.

[0006] The technical solution of the present invention is a processing device for a machine tool guide rail plug strip, including a support base, on one side of which a motor is fixedly installed. It also includes a rotating shaft rotatably connected to the support base, one end of the rotating shaft is connected to the output end of the motor, and a rotating frame is rotatably sleeved on the rotating shaft. A plurality of grinding rollers are evenly distributed on the rotating frame, and the grinding rollers can slide radially along the rotating frame. A reduction gear set is commonly connected between one side of the rotating frame and the rotating shaft. A transmission mechanism is arranged on the other side of the rotating frame, and the rotating shaft is in transmission cooperation with the transmission mechanism to drive the grinding rollers to rotate. Guide wheels are connected to both ends of the grinding rollers, and guide members are arranged on two opposite side walls of the support base. The guide member includes a guide plate slidably connected to the support base vertically, and a clamping member connected to the support base is arranged under the rotating frame;

[0007] The clamping member is used to clamp the plug strip to be ground. The motor drives the rotating shaft to rotate, the rotating frame drives the grinding rollers to rotate. When the guide wheel contacts the guide plate, the grinding roller connected to the guide wheel moves horizontally to rotate and grind the grinding surface of the plug strip.

[0008] With the above technical solution, after the plug strip is horizontally fixed on the clamping member, the motor drives the rotating shaft to rotate. The rotating shaft drives the rotating frame to rotate slowly through the reduction gear set. At the same time, the rotating shaft drives the grinding rollers to rotate quickly through the transmission mechanism, and the grinding rollers rotate following the rotating frame. When the grinding roller is located at the lower side, the guide wheels at both ends thereof rollingly contact the guide plate to perform moving guidance on the grinding roller, so that the grinding roller moves horizontally to grind the grinding surface of the plug strip. After multiple grinding rollers sequentially contact the plug strip, the grinding of the grinding surface of the plug strip is completed.

[0009] Further, the rotating frame includes two circular plates. Bearings are commonly connected between the circular plates and the rotating shaft, and a plurality of protective covers are commonly fixedly connected between the two circular plates. The plurality of protective covers are distributed at equal intervals in a ring shape.

[0010] With the above technical solution, the two circular plates and the protective covers cooperate to form a rotating frame. When the rotating shaft rotates, it drives the rotating frame and the grinding rollers installed on the rotating frame to rotate slowly.

[0011] Further, the number of grinding rollers is three, namely a rough grinding roller, a semi-finishing grinding roller and a finishing grinding roller. The grinding rollers are arranged in the protective covers, and sliders are rotatably connected to both ends of the grinding rollers. Notches adapted to the sliders are opened on the circular plates.

[0012] With the above technical solution, the fixed shafts at both ends of the grinding rollers are rotatably connected to the sliders, and the sliders are slidably matched with the notches, so that the grinding rollers can be displaced radially along the circular plates.

[0013] Further, the transmission mechanism includes a driving gear disk fixedly connected to the rotating shaft. A plurality of transmission gears are meshed and connected to one side of the driving gear disk. A bushing is fixedly connected to the side of the transmission gear facing the grinding roller. A spline shaft is slidably connected within the bushing. A double-shaft steering gear is commonly connected between the other end of the spline shaft and the grinding roller, and the double-shaft steering gear is fixedly connected to the slider.

[0014] Both the bushing and the spline shaft are rotatably connected to the side wall of the rotating frame, and an elastic member is commonly connected between the bushing and the spline shaft.

[0015] With the above technical solution, the rotating shaft drives the driving gear disk to rotate. The transmission gears are driven by the driving gear disk to drive the bushing to rotate. The bushing cooperates with the spline shaft and drives the grinding roller to rotate rapidly through the double-shaft steering gear. At the same time, by using the telescopic sliding fit between the bushing and the spline shaft, the grinding roller can still maintain transmission when moving radially along the circular plate.

[0016] Further, the guiding member includes a fixed seat fixedly connected to the side wall of the support seat. A sliding seat is slidably connected within the fixed seat. Oblique grooves are formed on both horizontally symmetric sides of the sliding seat. Link rods are slidably connected to the oblique grooves. Both lower ends of the two link rods are fixedly connected to the guiding plate. The guiding plate has a trapezoidal structure with the small head end facing downward.

[0017] With the above technical solution, the fixed seat has a U-shaped structure. The sliding seat can move horizontally along the fixed seat. When the sliding seat slides, the oblique grooves drive the link rods to rise or fall, and the link rods drive the guiding plate to move synchronously. By changing the height of the guiding plate, the effective contact pressure between each grinding roller and the grinding surface of the plug strip is always maintained, improving the grinding accuracy.

[0018] Further, a screw rod is rotatably connected to the fixed seat. One end of the screw rod is threadedly connected within the sliding seat, and the other end of the screw rod is fixedly connected with an adjusting gear.

[0019] On the side of the rotating frame facing the guiding member, there is a driving member. The driving member includes an outer arc rack and two inner arc racks. The outer arc rack and the inner arc racks are concentrically arranged and are both fixedly connected to the side wall of the rotating frame.

[0020] With the above technical solution, when the rotating frame rotates clockwise, the inner arc rack first contacts the adjusting gear to drive the screw rod to rotate. The screw rod drives the sliding seat to move towards the rotating frame side. The oblique grooves drive the link rods and the guiding plate to descend, changing the grinding pressure of the next grinding roller on the plug strip. When the outer arc rack contacts the adjusting gear, it drives the screw rod to rotate in the reverse direction, and the sliding seat moves in the reverse direction, restoring the guiding plate to its initial height, facilitating the grinding of the next plug strip.

[0021] Further, the clamping member includes a fixing plate horizontally slidably connected to the support base. A vertically penetrating through hole is provided in the fixing plate. Two clamping plates are arranged in the through hole. One of the clamping plates is fixedly connected to the fixing plate, and a plurality of bolts are rotatably connected to the other clamping plate. The bolts are threadedly connected to the fixing plate.

[0022] With the above technical solution, the plug strip can be arranged between the two clamping plates, with the grinding surface facing horizontally upward. Rotating the bolts drives the clamping plates to move, and the two clamping plates cooperate to clamp and fix the plug strip.

[0023] Further, the end of the fixing plate passes through the support base and extends outward. A driving hole is provided at one end of the fixing plate facing the motor. A driving roller is arranged in the driving hole. A connecting shaft is eccentrically connected to the top of the driving roller. The connecting shaft is rotatably connected to the support base. The other end of the connecting shaft and the rotating shaft are commonly connected with a double-axis steering gear, and the double-axis steering gear is fixedly connected to the side wall of the support base.

[0024] With the above technical solution, the rotating shaft drives the connecting shaft to rotate through the double-axis steering gear. The driving roller and the driving hole cooperate to drive the fixing plate to reciprocate horizontally. When the grinding roller rotates and grinds the plug strip, the plug strip itself performs a horizontal reciprocating motion, which helps to further improve the grinding accuracy and grinding efficiency.

[0025] Further, both ends of the bottom surface of the fixing plate are fixedly connected with fixing blocks. An L-shaped block is arranged on one side of the fixing block. The L-shaped block is hinged to the side wall of the support base far from the motor. The lower end of the L-shaped block abuts against the support base, and an inclined surface is provided on the side of the upper end of the L-shaped block facing the support base.

[0026] With the above technical solution, the cooperation between the fixing block and the L-shaped block enables the clamping member to perform a lifting motion during the horizontal reciprocation process, so that the whole clamping member makes a motion similar to a figure-eight. When the clamping member moves horizontally at a high position, it drives the plug strip to contact the grinding roller. The horizontal movement of the plug strip itself makes each area of the grinding surface alternately contact the grinding roller, avoiding local over-grinding and reducing uneven wear or surface depression of the material caused by fixed-point grinding. When the clamping member moves horizontally at a low position, the plug strip does not contact the grinding roller. The rapid rotation of the grinding roller itself drives the air around the plug strip to flow rapidly, enabling effective cooling of both the arc surface of the grinding roller and the grinding surface of the plug strip, avoiding the plug strip grinding surface generating high temperature during long-term grinding, which may cause annealing (reduction in hardness) and accelerate the wear of the plug strip.

[0027] Another object of the present invention is to provide a processing method for a machine tool guide rail plug strip, aiming to perform automatic step-by-step standardized grinding on the grinding surface of the plug strip.

[0028] To achieve the above object, the present invention provides the following technical solution: A processing method for a machine tool guide rail plug strip, comprising the following steps:

[0029] S1. Place the support base on the horizontal ground, and horizontally clamp and fix the plug strip through the clamping member;

[0030] S2. The motor drives the rotating shaft, the rotating shaft drives the rotating frame to rotate slowly, and at the same time the rotating shaft drives the grinding roller to rotate rapidly;

[0031] S3. When the guide wheel contacts the guide plate, the grinding roller connected to the guide wheel moves horizontally and rotates, and the bottom of the grinding roller rotates and grinds the surface of the plug strip;

[0032] S4. When the inner arc rack contacts the adjusting gear, the sliding seat moves to drive the guide plate to move vertically, changing the contact pressure between the next grinding roller and the plug strip. After all the grinding rollers have sequentially completed the rotational contact with the plug strip, the plug strip grinding is completed.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. While the rotating shaft drives the rotating frame to rotate slowly, it drives the grinding roller to rotate rapidly. When the guide wheels on both sides of the grinding roller contact the guide plate, the grinding roller moves horizontally to rotate and grind the plug strip. Multiple grinding rollers sequentially perform rough grinding, semi-finishing grinding, and finishing grinding on the plug strip, improving the grinding accuracy and standardization of the plug strip. At the same time, the structure of this device is compact and easy to move, and the plug strip can be ground on the spot of the machine tool, shortening the machine tool downtime.

[0035] 2. After the current grinding roller completes the grinding of the plug strip, the driving member drives the sliding seat to move, causing the guide plate to descend, reducing the height of the next grinding roller, and ensuring an effective grinding pressure between the next grinding roller and the grinding surface of the plug strip, thereby further improving the grinding accuracy of the plug strip.

[0036] 3. By making the clamping member itself perform a movement similar to a figure-eight, the grinding roller intermittently contacts the grinding roller. When the plug strip automatically moves and contacts the grinding roller, each area of the grinding surface of the plug strip alternately contacts the grinding roller, avoiding local over-grinding, which helps to further improve the grinding flatness. When the plug strip does not contact the grinding roller, it is beneficial for the grinding surface of the plug strip to cool quickly, avoiding annealing caused by high temperature on the grinding surface, and thus avoiding a reduction in the hardness of the plug strip.

Detailed implementation manners

[0049] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made with reference to the accompanying drawings of the specification.

[0050] Example 1, referring to Figures 1 - 8, which is the first embodiment of the present invention, provides a machining device for a machine tool guide strip, including a support base 1. A motor is fixedly installed on one side of the support base 1. It also includes a rotating shaft 2 rotatably connected to the support base 1. One end of the rotating shaft 2 is connected to the output end of the motor, and a rotating frame 3 is rotatably sleeved on the rotating shaft 2. A plurality of grinding rollers 4 are evenly distributed on the rotating frame 3. The grinding rollers 4 can slide radially along the rotating frame 3. A reduction gear set 6 is commonly connected between one side of the rotating frame 3 and the rotating shaft 2. A transmission mechanism 7 is arranged on the other side of the rotating frame 3. The rotating shaft 2 is in transmission cooperation with the transmission mechanism 7 to drive the grinding rollers 4 to rotate. Guide wheels 8 are connected to both ends of the grinding rollers 4. Guide members 9 are arranged on two opposite side walls of the support base 1. The guide member 9 includes a guide plate 95 slidably connected to the support base 1 vertically. A clamping member 11 connected to the support base 1 is provided under the rotating frame 3. The clamping member 11 is used to clamp the strip to be ground. The motor drives the rotating shaft 2 to rotate, and the rotating frame 3 drives the grinding rollers 4 to rotate. When the guide wheel 8 contacts the guide plate 95, the grinding roller 4 connected to the guide wheel 8 moves horizontally to grind the grinding surface of the strip.

[0051] Specifically, after the strip is horizontally fixed on the clamping member 11, the motor drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the rotating frame 3 to rotate slowly through the reduction gear set 6. At the same time, the rotating shaft 2 drives the grinding rollers 4 to rotate rapidly through the transmission mechanism 7, and the grinding rollers 4 rotate following the rotating frame 3. When the grinding rollers 4 are located at the lower side, the guide wheels 8 at both ends thereof rollingly contact the guide plate 95 to perform moving guidance on the grinding rollers 4, so that the grinding rollers 4 move horizontally to grind the grinding surface of the strip. After multiple grinding rollers 4 sequentially contact the strip, the grinding of the grinding surface of the strip is completed.

[0052] Refer to Figure 3 , the rotating frame 3 includes two circular plates 31. Bearings are commonly connected between the circular plates 31 and the rotating shaft 2, and a plurality of protective covers 32 are commonly fixed and connected between the two circular plates 31. The plurality of protective covers 32 are distributed at equal intervals in a ring shape.

[0053] Specifically, the two circular plates 31 and the protective covers 32 cooperate to form the rotating frame 3. When the rotating shaft 2 rotates, it drives the rotating frame 3 and the grinding rollers 4 installed on the rotating frame 3 to rotate slowly.

[0054] Among them, refer to Figure 4 , the reduction gear set 6 includes a first gear, an inner ring gear ring, a double gear, and a second gear. The first gear is fixedly sleeved on the shaft wall of the rotating shaft 2. The inner ring gear ring is fixedly connected to the side wall of one of the circular plates 31. The double gear and the second gear are both rotatably connected to the side wall of the support base 1, and the double gear is meshed and connected with the first gear and the second gear. The second gear is meshed and connected with the inner ring gear ring.

[0055] Refer to Figure 3, there are three grinding rollers 4, namely a rough grinding roller, a semi-finishing grinding roller and a finishing grinding roller. The grinding rollers 4 are arranged in the protective cover 32, and both ends of the grinding rollers 4 are rotatably connected with sliders 5. The circular plate 31 is provided with notches adapted to the sliders 5.

[0056] Specifically, the fixed shafts at both ends of the grinding roller 4 are rotatably connected with the sliders 5, and the sliders 5 are slidably matched with the notches, so that the grinding roller 4 can be displaced along the radial direction of the circular plate 31.

[0057] It can be understood that the arc surface of the grinding roller 4 is made of silicon carbide material. Starting from the upper side in the clockwise direction, the particle sizes of the surfaces of the three grinding rollers 4 are 80-120 mesh, 24-60 mesh and 150-400 mesh respectively. Among them, the grinding roller 4 with 24-60 mesh coarsely grinds the plug strip, quickly removing the worn layer or oxide skin on the surface of the plug strip. The grinding roller 4 with 80-120 mesh semi-finishes the plug strip to balance the efficiency and surface quality. The grinding roller 4 with 150-400 mesh finely grinds the plug strip and polishes the grinding surface of the plug strip to achieve a high surface finish with Ra (roughness) ≤ 1.6 μm.

[0058] Refer to Figures 5 - 6 , the transmission mechanism 7 includes a driving gear disk 71 fixedly connected to the rotating shaft 2. A plurality of transmission gears 72 are meshed and connected to one side of the driving gear disk 71. A sleeve 73 is fixedly connected to the side of the transmission gear 72 facing the grinding roller 4. A spline shaft 74 is slidably connected in the sleeve 73. A double-axis steering gear is commonly connected between the other end of the spline shaft 74 and the grinding roller 4, and the double-axis steering gear is fixedly connected to the slider 5; both the sleeve 73 and the spline shaft 74 are rotatably connected to the side wall of the rotating frame 3, and an elastic member 75 is commonly connected between the sleeve 73 and the spline shaft 74.

[0059] Specifically, the rotating shaft 2 drives the driving gear disk 71 to rotate. The transmission gear 72 is driven by the driving gear disk 71 to drive the sleeve 73 to rotate. The sleeve 73 cooperates with the spline shaft 74 and drives the grinding roller 4 to rotate rapidly through the double-axis steering gear. At the same time, by using the telescopic sliding fit between the sleeve 73 and the spline shaft 74, the grinding roller 4 can still maintain transmission when moving along the radial direction of the circular plate 31.

[0060] Among them, refer to Figure 3 、 Figure 6 And Figure 8 , the elastic member 75 is a spring. The spring is sleeved outside the sleeve 73 and is fixedly connected to the outer wall of the sleeve 73 and the outer wall of the spline shaft 74 at both ends. When the guide wheel 8 does not contact the guide plate 95, the spring drives the spline shaft 74 to contract into the sleeve 73, so that the slider 5 fits with the inner end of the notch.

[0061] Refer to Figure 2 And Figure 8, the guide wheel 8 on the side of the grinding roller 4 close to the motor is fixedly connected to the side wall of the slider 5, and the guide wheel 8 on the other side of the grinding roller 4 is fixedly connected to the side wall of the double-axis steering gear.

[0062] Refer to Figure 1 and Figure 9 , the clamping member 11 includes a fixing plate 111 that is horizontally slidably connected to the support base 1. A vertically penetrating through-hole is provided on the fixing plate 111. Two clamping plates 112 are provided in the through-hole. One of the clamping plates 112 is fixedly connected to the fixing plate 111, and a plurality of bolts 113 are rotatably connected to the other clamping plate 112. The bolts 113 are threadedly connected to the fixing plate 111.

[0063] Specifically, the plug strip can be arranged between the two clamping plates 112 so that the grinding surface is horizontally upward. Rotating the bolt 113 drives the clamping plate 112 to move, and the two clamping plates 112 cooperate to clamp and fix the plug strip.

[0064] Embodiment 2, refer to Figure 2 、 Figure 7 and Figure 8 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the guiding member 9 includes a fixing base 91 fixedly connected to the side wall of the support base 1. A sliding seat 92 is slidably connected in the fixing base 91. Oblique grooves 93 are provided on both horizontally symmetric sides of the sliding seat 92. Link rods 94 are slidably connected to the oblique grooves 93. The lower ends of the two link rods 94 are fixedly connected to a guiding plate 95. The guiding plate 95 has a trapezoidal structure with the small head end facing downward.

[0065] Specifically, the fixing base 91 has a U-shaped structure. The sliding seat 92 can move horizontally along the fixing base 91. When the sliding seat 92 slides, the oblique groove 93 drives the link rod 94 to rise or fall, and the link rod 94 drives the guiding plate 95 to move synchronously. By changing the height of the guiding plate 95, the effective contact pressure between each grinding roller 4 and the grinding surface of the plug strip is always maintained, improving the grinding accuracy.

[0066] Refer to Figure 7 and Figure 8 , a screw rod 96 is rotatably connected to the fixing base 91. One end of the screw rod 96 is threadedly connected to the sliding seat 92, and the other end of the screw rod 96 is fixedly connected to an adjusting gear 97; on the side of the rotating frame 3 facing the guiding member 9, there is a driving member 10. The driving member 10 includes an outer arc rack 101 and two inner arc racks 102. The outer arc rack 101 and the inner arc racks 102 are concentrically arranged and are both fixedly connected to the side wall of the rotating frame 3.

[0067] Specifically, when the rotating frame 3 rotates clockwise, the inner arc rack 102 first contacts the adjusting gear 97 to drive the screw 96 to rotate. The screw 96 drives the sliding seat 92 to move towards the rotating frame 3. The inclined groove 93 drives the connecting rod 94 and the guide plate 95 to descend, changing the grinding pressure of the next grinding roller 4 on the plug strip. When the outer arc rack 101 contacts the adjusting gear 97, it drives the screw 96 to rotate in the reverse direction, and the sliding seat 92 moves in the reverse direction, causing the guide plate 95 to return to its initial height, facilitating the grinding of the next plug strip.

[0068] Among them, referring to Figure 8 , after the rough grinding roller on the lower right side finishes rough grinding the plug strip, the inner arc rack 102 in the middle on the right contacts the adjusting gear 97. The screw 96 drives the sliding seat 92 to move towards the rotating frame 3. The guide plate 95 descends a certain height, making the height of the semi-finishing grinding roller on the upper side slightly lower than that of the rough grinding roller when it is located on the lower side, thereby compensating for the height loss of the plug strip surface after rough grinding and ensuring that the semi-finishing grinding roller maintains an effective grinding pressure on the plug strip. Similarly, when the inner arc rack 102 in the upper left contacts the adjusting gear 97, the sliding seat 92 continues to move towards the rotating frame 3, and the guide plate 95 continues to descend a certain height, making the height of the finishing grinding roller on the lower left slightly lower than that of the semi-finishing grinding roller when it is located on the lower side. After the finishing grinding roller finishes grinding the plug strip, the outer arc rack 101 contacts the adjusting gear 97 to drive the screw 96 to rotate in the reverse direction, and the sliding seat 92 moves in the reverse direction to drive the guide plate 95 to rise to its initial height.

[0069] In actual work, during multiple uses of the grinding roller 4, the arc surface of its own will be worn, resulting in a reduction in the contact pressure between the grinding roller 4 and the plug strip. By manually driving the adjusting gear 97 to rotate when the device stops working and changing the height of the guide plate 95, it can be used to compensate for the wear of all the grinding rollers 4 themselves, thereby ensuring that all the grinding rollers 4 maintain an effective grinding pressure on the plug strip. The remaining structure is the same as that of Embodiment 1.

[0070] Embodiment 3, referring to Figure 9 , is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the end of the fixing plate 111 passes through the support seat 1 and extends outward, and a driving hole is provided at one end of the fixing plate 111 facing the motor. A driving roller 12 is provided in the driving hole. An eccentric shaft 13 is connected to the top of the driving roller 12. The eccentric shaft 13 is rotatably connected to the support seat 1, and the other end of the eccentric shaft 13 and the rotating shaft 2 are commonly connected with a double-axis steering gear, and the double-axis steering gear is fixedly connected to the side wall of the support seat 1.

[0071] Specifically, the rotating shaft 2 drives the eccentric shaft 13 to rotate through the double-axis steering gear. The driving roller 12 cooperates with the driving hole to drive the fixing plate 111 to perform a horizontal reciprocating motion, so that when the grinding roller 4 rotates and grinds the plug strip, the plug strip itself performs a horizontal reciprocating motion, which helps to further improve the grinding accuracy and grinding efficiency.

[0072] Among them, the biaxial steering gear connected to the coupling shaft 13 is a right-angle reducer. The rotation speed of the coupling shaft 13 is reduced through the right-angle reducer, so that the driving roller 12 drives the clamping member 11 to make a slow reciprocating motion, avoiding the displacement of the plug strip caused by high-frequency vibration.

[0073] Referring to Figure 10 , fixed blocks 14 are fixedly connected to both ends of the bottom surface of the fixing plate 111. An L-shaped block 15 is provided on one side of the fixed block 14. The L-shaped block 15 is hinged to the side wall of the support base 1 away from the motor. The lower end of the L-shaped block 15 is in abutting cooperation with the support base 1, and an inclined surface is formed on the side of the upper end of the L-shaped block 15 facing the support base 1.

[0074] Specifically, through the cooperation of the fixed block 14 and the L-shaped block 15, the clamping member 11 makes a lifting motion during the horizontal reciprocation process, so that the clamping member 11 as a whole makes a motion similar to a figure-eight. When the clamping member 11 moves horizontally at a high position, it drives the plug strip to contact the grinding roller 4. The horizontal movement of the plug strip itself makes each area of the grinding surface alternately contact the grinding roller 4, avoiding local over-grinding and reducing uneven wear or surface depression of the material caused by fixed-point grinding. When the clamping member 11 moves horizontally at a low position, the plug strip does not contact the grinding roller 4. The rapid rotation of the grinding roller 4 itself drives the air around the plug strip to flow rapidly, enabling effective cooling of both the arc surface of the grinding roller 4 and the grinding surface of the plug strip, avoiding the plug strip grinding surface from generating high temperature during long-term grinding, which may cause annealing (reduction in hardness) and accelerate the wear of the plug strip.

[0075] Among them, referring to Figure 10 , when the fixing plate 111 moves to the right, the right end of the fixed block 14 contacts the left side of the upper end of the L-shaped block 15 and drives the L-shaped block 15 to rotate clockwise. When the fixing plate 111 moves horizontally to the right and the contact between the fixed block 14 and the L-shaped block 15 is cancelled, the lower end of the L-shaped block 15 abuts against the side wall of the support base 1 again under the action of gravity. At this time, when the fixing plate 111 moves from the right to the left, the left end of the fixed block 14 contacts the inclined surface of the L-shaped block 15. Since the L-shaped block 15 cannot rotate counterclockwise, the bottom surface of the fixed block 14 slides in contact with the top surface of the L-shaped block 15, causing the fixing plate 111 to move upward as a whole and then translate when moving to the left, thereby realizing the figure-eight-like motion of the clamping member 11. The rest of the structure is the same as that of Embodiment 2.

[0076] Combining Embodiments 1 - 3, the working principle of the present invention is as follows: Place the polished surface of the plug strip upward into the through - hole of the fixed plate 111, and rotate the bolt 113 to clamp and fix the plug strip with two clamping plates 112. The motor drives the rotating shaft 2, and the rotating shaft 2 drives the rotating frame 3 to rotate slowly through the reduction gear set 6. At the same time, the rotating shaft 2 drives the grinding roller 4 to rotate rapidly through the transmission mechanism 7. When the grinding roller 4 is on the lower side, the guide wheels 8 on both sides of the grinding roller 4 rollingly contact the bottom of the guide plate 95, causing the grinding roller 4 to move horizontally and rotate, and rotate - grind the polished surface of the plug strip. When the rotating frame 3 rotates one circle, the three grinding rollers 4 sequentially grind the plug strip to different degrees.

[0077] Embodiment 4, referring to Figures 1 - 9 , which is the fourth embodiment of the present invention, provides: A processing method for a machine tool guide rail plug strip, including the following steps:

[0078] S1. Place the support base 1 on the horizontal ground and horizontally clamp and fix the plug strip through the clamping member 11;

[0079] S2. The motor drives the rotating shaft 2, and the rotating shaft 2 drives the rotating frame 3 to rotate slowly, and at the same time, the rotating shaft 2 drives the grinding roller 4 to rotate rapidly;

[0080] S3. When the guide wheel 8 contacts the guide plate 95, the grinding roller 4 connected to the guide wheel 8 moves horizontally and rotates, and the bottom of the grinding roller 4 rotates - grinds the surface of the plug strip;

[0081] S4. When the inner arc rack 102 contacts the adjusting gear 97, the sliding seat 92 moves to drive the guide plate 95 to move vertically, changing the contact pressure between the next grinding roller 4 and the plug strip. After all the grinding rollers 4 sequentially complete the rotational contact with the plug strip, the grinding of the plug strip is completed.

[0082] It should be noted that the above - mentioned embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
