Description

Technical Field

[0001] The invention relates to the field of feeding mechanisms, and in particular to an X-axis feeding mechanism of a grinding machine and a use method thereof. Background Art

[0002] The X-axis feed mechanism of the existing grinder is realized by directly driving the slide table through the lead screw and cooperating with the lead screw nut and the slide rail. However, the assembly between the lead screw and the slide rail is prone to excessive constraints, which is difficult to debug and easily affects the surface finish and parallelism of the workpiece. The excessive constraints between the lead screw and the slide rail will also increase the wear of the lead screw and the slide rail, affecting the service life. In addition, there is a gap between the lead screw and the support bearings and the lead screw nut at both ends of the lead screw. The support bearing needs to be pre-tightened by nut locking to eliminate this gap. However, the rolling elements and raceways of the lead screw nut will wear after pre-tightening, and further pre-tightening is required after a period of time. This requires professionals to regularly repair the grinder, which will increase labor costs. Using other methods for pre-tightening will increase the complexity of the structure and increase production costs. Summary of the invention

[0026] Reference Figure 1 The present invention discloses an X-axis feeding mechanism of a grinding machine, including a base 100, a positioning assembly 200, a slide table 300 and a driving cylinder 400.

[0027] The positioning assembly 200 includes a lead screw 210 and a fixed seat 220, a lead screw nut 230 and a motor 240 arranged in sequence along the X-axis direction. The fixed seat 220 and the lead screw nut 230 are fixedly mounted on the base 100. The motor 240 is slidably arranged on the base 100 along the X-axis direction. The lead screw 210 is arranged along the X-axis direction and can move along the X-axis direction. The left part of the lead screw 210 is provided with an optical axis section 211, which is slidably arranged on the fixed seat 220. The left end of the lead screw 210 extends out of the fixed seat 220. The lead screw 210 is provided with a threaded section 212. Segment 212 is located on the right side of the optical axis segment 211 and cooperates with the screw nut 230. The right end of the screw 210 extends out of the screw nut 230 and is connected to the output shaft of the motor 240. The output shaft of the motor 240 can rotate around its own axis and drive the screw 210 to rotate around the X-axis; the slide 300 is provided with a first gear position 310, and the slide 300 can press against the left end of the screw 210 at the first gear position 310. The drive cylinder 400 is provided on the base 100. The piston rod of the drive cylinder 400 can be extended and retracted along the X-axis direction and can drive the slide 300 to slide relative to the base 100 along the X-axis direction.

[0028] It can be understood that after starting the motor 240, the motor 240 can drive the screw 210 to rotate, thereby causing the motor 240 and the screw 210 to slide to the left to the initial position at the same time. At this time, the motor 240 is paused and the drive cylinder 400 is started, so that the drive cylinder 400 drives the slide 300 to slide to the right until the first gear 310 hits the left end of the screw 210 and then restarts the motor 240. At this time, the motor 240 drives the screw 210 to rotate in the opposite direction, thereby causing the motor 240 and the screw 210 to slide to the right at the same time, and the slide 300 continues to hit the left end of the screw 210, so that the slide 300 is fed and positioned along the X-axis direction. Finally, the drive cylinder 400 releases the pressure, and the motor 240 drives the screw 210 to rotate in the opposite direction of the feed. Since the lead screw 210 in the present invention does not directly drive the slide 300 to slide along the X-axis direction, the influence of assembly accuracy problems on the surface finish and parallelism of the workpiece can be eliminated; both ends of the lead screw 210 are supported by the fixed seat 220 and the lead screw nut 230, and there is no need to use support bearings, and since the slide 300 can eliminate the gap between the lead screw 210 and the lead screw nut 230 after abutting against the lead screw 210, when the slide 300 and the lead screw 210 are fed and positioned to the right along the X-axis direction, the influence of the gap between the lead screw 210 and the lead screw nut 230 on the workpiece processing can be eliminated, and there is no need to use nut locking methods to pre-tighten the support bearings regularly, which can reduce labor costs and production costs.

[0029] In some embodiments of the present invention, a motor base 500 is further included, which is slidably arranged on the base 100 along the X-axis direction. The motor 240 is arranged on the motor base 500. A buffer member 600 is arranged on the motor base 500. The buffer member 600 has a collision head 610 that can be extended and retracted along the left and right directions. The collision head 610 can elastically press against the slide table 300 in a sliding state. The slide table 300 is provided with a second gear position 320. The collision head 610 can elastically press against the second gear position 320. The distance between the collision head 610 and the second gear position 320 along the X-axis direction is smaller than the distance between the left end of the screw 210 and the first gear position 310 along the X-axis direction. When the slide 300 slides to the right, the second gear 320 on the slide 300 will first touch the impact head 610 of the buffer 600, and the impact head 610 will shrink to the right to buffer the slide 300. The buffered slide 300 will reduce the sliding speed and continue to slide to the right until the first gear 310 of the slide 300 hits the left end of the screw 210. The buffer 600 can buffer the slide 300 to prevent the slide 300 from directly hitting the screw 210 and impacting the screw 210.

[0030] In some embodiments of the present invention, a first slide rail 110 and a second slide rail 120 are provided on the base 100, and both the first slide rail 110 and the second slide rail 120 extend along the X-axis direction. The motor base 500 is slidably provided on the first slide rail 110, and the slide table 300 is slidably provided on the second slide rail 120. The motor base 500 can drive the motor 240 provided on the motor base 500 to move along the first slide rail 110, and the motor 240 can drive the lead screw 210 to move, and the slide table 300 can move along the second slide rail 120. Therefore, the lead screw 210 does not need to directly drive the slide table 300 to move, and the smoothness and parallelism of the surface of the workpiece can be avoided due to the transition constraint problem of the assembly between the lead screw 210 and the slide rail 300.

[0031] In some embodiments of the present invention, a grating ruler 700 is further included. The grating ruler 700 includes a scale grating 710 and a grating reading head 720. The scale grating 710 is fixed on the base 100 along the X-axis direction. The grating reading head 720 is arranged on the slide 300 and can slide relative to the scale grating 710 along the X-axis direction under the drive of the slide 300. The grating ruler 700 is used to detect the displacement of the slide 300 along the X-axis direction. The grating ruler 700 can perform closed-loop control on the displacement of the slide 300 along the X-axis direction to accurately process the workpiece.

[0032] In some embodiments of the present invention, a wear-resistant block 311 is provided at the first gear position 310, and the slide 300 abuts against the left end of the lead screw 210 through the wear-resistant block 311. In the process of the slide 300 abutting against the lead screw 210, there will be friction and impact force between the slide 300 and the lead screw 210, which may easily cause the slide 300 to wear. The wear-resistant block 311 is provided on the slide 300 to increase the service life of the slide 300. Specifically, the left end of the lead screw 210 is an arc surface, and the wear-resistant block 311 abuts against the arc surface of the lead screw 210.

[0033] In some embodiments of the present invention, the piston rod of the driving cylinder 400 is hinged to the slide 300 via a pin 410 .

[0034] Specifically, a processing tool 330 is disposed on the slide 300. The processing tool 330 may be a tool capable of processing a workpiece, including but not limited to a grinding wheel.

[0035] The present invention also discloses a method for using the X-axis feeding mechanism of a grinding machine, comprising the following steps:

[0036] S1, start the motor 240, so that the output shaft of the motor 240 drives the lead screw 210 to rotate around the X-axis, and through the rotational feeding cooperation between the lead screw 210 and the lead screw nut 230, the motor 240 and the lead screw 210 are simultaneously moved to the left to the initial position, and then the motor 240 is stopped;

[0037] S2, start the drive cylinder 400, so that the piston rod of the drive cylinder 400 drives the slide 300 to slide to the right, until the first gear 310 of the slide 300 hits the left end of the lead screw 210;

[0038] S3, restart the motor 240 and make the output shaft of the motor 240 rotate in the opposite direction, so that the motor 240 and the lead screw 210 move to the right at the same time, and the slide 300 continues to press against the left end of the lead screw 210 to feed and position the slide 300 to the right along the X-axis direction. The slide 300 is provided with a processing tool 330, and the processing tool 330 can process the workpiece until the processing is completed;

[0039] S4, the driving cylinder 400 releases the pressure, and the motor 240 drives the lead screw 210 to rotate in the reverse direction and withdraw in the opposite direction of the feeding.

[0040] It can be understood that since the screw 210 in the present invention does not directly drive the slide 300 to slide along the X-axis direction, the influence of assembly accuracy problems on the surface finish and parallelism of the workpiece can be eliminated; the two ends of the screw 210 are supported by the fixed seat 220 and the screw nut 230, and there is no need to use support bearings, and since the slide 300 can eliminate the gap between the screw 210 and the screw nut 230 after it hits the screw 210, when the slide 300 and the screw 210 are fed and positioned to the right along the X-axis direction, the influence of the gap between the screw 210 and the screw nut 230 on the workpiece processing can be eliminated, and there is no need to use nut locking methods to pre-tighten the support bearings regularly, which can reduce labor costs and production costs.

[0041] The present invention also provides another embodiment, comprising the following steps:

[0042] S1, start the motor 240, so that the output shaft of the motor 240 drives the lead screw 210 to rotate around the X-axis, and through the rotational feeding cooperation between the lead screw 210 and the lead screw nut 230, the motor 240 and the lead screw 210 are simultaneously moved to the left to the initial position, and then the motor 240 is stopped;

[0043] S2, start the driving cylinder 400, so that the piston rod of the driving cylinder 400 drives the slide 300 to slide to the right, wherein the base 100 is provided with a motor seat 500 for sliding along the X-axis direction, the motor 240 is arranged on the motor seat 500, and the motor seat 500 is provided with a buffer 600, the buffer 600 has a collision head 610 that can be extended and retracted along the left and right directions, the collision head 610 can elastically press against the slide 300 in a sliding state, the slide 300 is provided with a second gear 320, the collision head 610 can elastically press against the second gear 320, the distance between the collision head 610 and the second gear 320 along the X-axis direction is smaller than the distance between the left end of the lead screw 210 and the first gear 310 along the X-axis direction, when the slide 300 slides to the right, it first presses against the collision head 610 through the second gear 320 for buffering, until the slide 300 presses against the left end of the lead screw 210 through the first gear 310;

[0044] S3, restart the motor 240 and make the output shaft of the motor 240 rotate in the opposite direction, so that the motor 240 and the lead screw 210 move to the right at the same time, and the slide 300 continues to press against the left end of the lead screw 210 to feed and position the slide 300 to the right along the X-axis direction. The slide 300 is provided with a processing tool 330, and the processing tool 330 can process the workpiece until the processing is completed;

[0045] S4, the driving cylinder 400 releases the pressure, and the motor 240 drives the lead screw 210 to rotate in the reverse direction and withdraw in the opposite direction of the feeding.

[0046] Among them, when the slide 300 slides to the right, the second gear 320 on the slide 300 will first touch the impact head 610 of the buffer 600, and the impact head 610 will shrink to the right to buffer the slide 300. The buffered slide 300 will reduce the sliding speed and continue to slide to the right until the first gear 310 of the slide 300 hits the left end of the screw 210. The buffer 600 can buffer the slide 300 to prevent the slide 300 from directly hitting the screw 210 and impacting the screw 210.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
