Abstract

The present application belongs to the technical field of straightening, and particularly relates to a straight line guide rail straightening machine, which comprises guide rail clamps arranged on the top of a machining table and located at the left and right side edges, guide rail strips movably sleeved on the inner side walls of the guide rail clamps, and a sliding block two movably sleeved on the inner side walls of the machining table. The sliding block two comprises an extrusion fine adjustment unit, and the extrusion fine adjustment unit comprises a fixed plate one. A plurality of threaded sleeves are movably sleeved on the outer side surface of the fixed plate one. When the bending amplitude on the top surface of the guide rail strip is greater than the error gap, the sliding block three directly extrudes on the bottom end surface of the sliding column through the error gap, moves the sliding column in the opposite direction at a perpendicular angle into the inside of the limiting sleeve, thereby extruding the V-shaped extrusion strip, and the length of the V-shaped extrusion strip does not change when the arc on the surface of the V-shaped extrusion strip is extruded and bent, so that the V-shaped extrusion strip is folded in half and moved towards the middle.

Description

Technical Field

[0001] This invention belongs to the field of linear alignment technology, specifically a linear guide rail straightening machine. Background Technology

[0002] Linear guides, also known as linear rails, slide rails, or linear guideways, are used in linear reciprocating motion applications and can withstand a certain amount of torque, achieving high-precision linear motion under high loads. During the forming process, linear products such as linear guides may experience bending or torsional deformation due to incomplete release of residual stress. Furthermore, linear guides may deform during handling, installation, and use. As precision parts with high requirements for dimensional accuracy, calibration is an essential process and a crucial step in linear guide production.

[0003] A Chinese patent with publication number CN107900149A discloses an automatic linear guide rail straightening machine. The straightening machine includes a first guide rail placement frame, a straightening mechanism, a second guide rail placement frame, an operation control board, and a PLC electrical control box. The first and second guide rail placement frames are located on opposite sides of the straightening mechanism. The operation control board is connected to the straightening mechanism and the PLC electrical control box via a data cable. The straightening mechanism includes a straightening workbench, positioning components, guide columns, a pressing motor, a reducer, a support plate, a pressing lead screw, a lead screw nut, a pressing connecting plate, and pressing rollers. The linear guide rail to be straightened is placed on the positioning component 2-2 on the straightening workbench 2-1. The first guide rail placement frame 1 and the second guide rail placement frame 3 support the two ends of the linear guide rail extending from the straightening workbench 2-1. The operator measures the straightening data and controls the pressing rollers 2-10 to perform straightening by operating the rocker arm 4-1 and button 4-2 on the control panel 4. The straightening results are observed on the display 6. For specific straightening operation methods, please refer to existing technologies.

[0004] Currently, existing linear guide straightening devices use lasers to detect curvature on the guide rail surface, employing manual or semi-automatic hydraulic straightening methods. However, laser detection can only observe curvature, and the guide rail surface may have certain errors during production. Laser detection cannot control the convexity within these errors, causing the rolling device to perform secondary rolling on convexities within the specified values. This results in repetitive work, affecting efficiency, and the secondary rolling can easily lead to excessive pressure, damaging the guide rail surface and causing excessive bending.

[0005] Therefore, the present invention provides a linear guide straightening machine. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is: a linear guide rail straightening machine according to this invention, comprising:

[0008] A guide rail clamp is installed on the top of the machining table and located at the left and right edges;

[0009] The guide rail is movably sleeved on the inner wall of the guide rail holder;

[0010] Slider 2, which is slidably fitted onto the inner wall of the machining table

[0011] The second slider includes a compression fine-tuning unit, which includes a fixing plate. Multiple threaded collars are threadedly fitted onto the outer surface of the fixing plate. A limiting sleeve is fixedly connected to the inner wall of each threaded collar. V-shaped compression strips are symmetrically fixedly connected to the inner top walls of both sides of the limiting sleeve. A sliding post, fixedly connected to the bottom surface of the V-shaped compression strip, is slidably fitted onto the inner wall of the limiting sleeve. An elastic wire is fixedly connected to the top surface of the sliding post, located at the perimeter of the V-shaped compression strip. The other end is fixedly connected to the inner wall of the top of the limiting sleeve. A micro-elastic steel wire is fixedly connected to the bottom surface of the sliding column. At this time, the error gap between one end of the sliding column and the inner wall of the slider three is within the normal range of the convex arc on the surface of the guide rail. When the slider three slides past the normal value, under the reverse push of the micro-elastic steel wire, the slider three is re-attached to the top surface of the guide rail. The arc on the outer surface of the top of the slider three fits onto the outer surface of the bottom end of the sliding column, so that when the slider three slides, it bends and fits the bottom of the sliding column. The end surface limits its position to avoid excessive bending. A slider three, which is movably sleeved on the outer surface of the bottom end of the sliding column, is fixedly connected to the other end of the micro-elastic steel wire. The guide rail is sleeved on both ends of the guide rail holder, pressing and fixing it in place. Sliding slider two slides from one end to the other on the surface of the processing table, while slider three slides against the top surface of the guide rail. When it encounters a convex arc on the top surface of the guide rail, the convex arc will press slider three upwards in the opposite direction. An error gap is provided between one end of the slider three and the slide column. When the curvature of the top surface of the guide rail is greater than the error gap, the slider three will pass through the error gap and directly press against the bottom surface of the slide column. The slide column will move into the inside of the limiting sleeve at a vertical angle, thereby pressing the V-shaped extrusion strip. As the slider three slides down, the bottom surface moves away from the arc of the top surface of the guide rail. The arc of the bottom surface of the slider three no longer protrudes. Under the reverse extrusion of the elastic wire, the slide column is pressed down from the inside of the limiting sleeve.

[0012] The upper inner walls of both sides of the limiting sleeve are symmetrically and fixedly connected with conductive wires. The other end of the conductive wires is fixedly connected to the middle position of the outer side of the V-shaped extrusion strip. A current-carrying wire is fixedly connected to the middle position of the upper inner side of the limiting sleeve, which is located at the middle edge of the two conductive wires. When the V-shaped extrusion strip is compressed and bent, the V-shaped extrusion strip, whose length remains unchanged, is folded in half and brought closer to the middle, thereby adhering the conductive wires on the inner surface to the surface of the current-carrying wire. When the current-carrying wire and the conductive wire are adhering, electricity is generated between them, thereby triggering an alarm to the external controller. This straightens the protruding arc on the surface of the guide rail. At the same time, the inner wall of the limiting sleeve pushes the sliding column at a vertically downward angle. When the sliding column slides down, it pulls the V-shaped extrusion strip, which is stretched and the angle expands, causing the conductive wires on the surface of the V-shaped extrusion strip to detach from the surface of the current-carrying wire, thereby turning off the alarm.

[0013] Preferably, a second conductive wire is fixedly installed at the top center of the limiting sleeve, which is disposed on one end of the energizing wire. A second fixing plate is fixedly connected to one end of the second conductive wire, and an indicator light is fixedly installed on one side edge of the top of the second fixing plate. One end of the second conductive wire is linearly connected to the linear receiving end of the indicator light.

[0014] Preferably, a correction frame is fixedly connected to the outer surface of the first fixing plate and disposed on the outer surface of the second slider, and a support rod is fixedly connected to the top surface of the correction frame and located at the four corners.

[0015] Preferably, a downward pressure correction plate is fixedly installed on the inner wall of the top of the support rod at the middle position, and one end of the downward pressure correction plate passes through the inner wall of the correction frame and movably overlaps the top outer surface of the guide rail.

[0016] Preferably, a wear-resistant layer is fixedly connected to the top surface of the processing table, and a sliding track is fixedly connected to the inner wall of the processing table at the top edge position, which is movably sleeved on the outer surface of the second slider.

[0017] Preferably, a groove is formed on the top surface of the processing table at the middle position of the bottom of the wear-resistant layer, and a double-strand limiting rod is fixedly connected to the inner wall of the groove. A slider that slides on the inner wall of the groove is slidably sleeved on the outer surface of the double-strand limiting rod.

[0018] Preferably, the two sides of the straightening frame are symmetrically fixedly connected with limiting telescopic plates. An upward straightening plate is fixedly installed on the inner bottom edge of the limiting telescopic plate. As the slider two slides on the inner wall of the sliding track, if a protrusion appears on the surface of the guide rail, the limiting telescopic plate will pull back the upward straightening plate. A docking limiting rod is fixedly installed on the top surface of the upward straightening plate and at the four edges. The docking limiting rod on the top surface of the upward straightening plate is sleeved onto the bottom surface of the straightening frame and fixedly docked. The downward straightening plate presses down on the top surface of the guide rail, squeezing and restoring some slightly protruding positions on the surface of the guide rail. If the bending is too large, the bottom upward straightening plate will no longer rise. Using the gap between the guide rail and the upward straightening plate, the position of the guide rail is squeezed and shaped under the pressure of the downward straightening plate. A sliding plate that movably overlaps the top outer surface of the wear-resistant layer is fixedly connected to the bottom surface of the upward straightening plate.

[0019] Preferably, there are two sets of guide rail holders. One set of guide rail holders is fixedly installed at the top edge of the wear-resistant layer, and the bottom surface of the other set of guide rail holders is fixedly installed on the top surface of the slider. The inner wall of the straightening frame and the upward straightening plate is movably sleeved on the outer surface of the guide rail. After the guide rail holders fix the two ends of the guide rail, the top surface of the guide rail will overlap and fit against the top inner wall of the straightening frame.

[0020] Preferably, a limiting rod is fixedly connected to the inner wall of the guide rail holder at the four corner positions. A mating clamping plate that overlaps the outer surface of the wear-resistant layer is movably sleeved on the outer surface of the limiting rod. When the mating clamping plate slides, it works with the limiting rod to limit the position of the mating clamping plate. This allows the mating clamping plate to move horizontally using the limiting rod and the threaded rod, preventing positional deviation that could lead to uneven contact on the surface of the guide rail and cause surface deviation of the guide rail.

[0021] Preferably, the inner surfaces of the guide rail holder and the docking clamping plate are fixedly connected with compression pads that adhere to the outer surface of the guide rail. These compression pads work together to gently compress some toothed tracks on both sides of the guide rail, increasing the contact force. The soft compression pads do not cause excessive compression damage to the guide rails on both sides of the guide rail. A threaded rod is movably sleeved on the bottom outer surface of the guide rail holder. The outer surface of the threaded rod is threaded onto the inner bottom wall of the docking clamping plate. When the guide rail is placed into the inner surfaces of the guide rail holder and the docking clamping plate, rotating the threaded rod causes the docking clamping plate on the outer surface of the threaded rod to slide to one side, pushing and compressing the guide rail to one end.

[0022] The beneficial effects of this invention are as follows:

[0023] 1. The linear guide straightening machine of the present invention, when the bending amplitude of the top surface of the guide rail is greater than the error gap, the slider will pass through the error gap and directly press against the bottom surface of the slide column, moving the slide column in the opposite direction at a vertical angle into the interior of the limiting sleeve, thereby pressing the V-shaped extrusion strip. Under the extrusion bending, the V-shaped extrusion strip, whose length remains unchanged, is folded in half and brought closer to the center, thereby adhering the conductive wire on the surface of the V-shaped extrusion strip to the surface of the conductive wire. When the conductive wire and the conductive wire are adhered, electricity will be generated between them, thereby transmitting power to the external controller. The alarm is triggered, and the protruding arc on the surface of the guide rail is straightened by compression. As the bottom surface of slider three continues to slide, it moves away from the arc on the top surface of the guide rail. The arc on the bottom surface of slider three is no longer protruding. Under the reverse compression of the elastic wire, the sliding column is squeezed downward from the inside of the limiting sleeve. At the same time, the inner wall of the limiting sleeve pushes the sliding column at a vertical downward angle. When the sliding column slides down, it pulls the V-shaped extrusion strip. The V-shaped extrusion strip is stretched and the angle expands, so that the conductive wire 1 on the surface of the V-shaped extrusion strip falls off the surface of the current-carrying wire, thereby turning off the alarm.

[0024] 2. The linear guide straightening machine of the present invention involves fitting a guide rail onto both ends of a guide rail holder and pressing and fixing it in place. A second slider slides from one end to the other on the surface of the processing table, while a third slider slides against the top surface of the guide rail. When the slider encounters a protruding arc on the top surface of the guide rail, the arc will press the third slider upwards in the opposite direction. At this time, the error gap between one end of the slide column and the inner wall of the third slider is within the normal range of the protruding arc on the guide rail surface. After the third slider passes the normal value, under the reverse push of the micro-elastic steel wire, the third slider is re-attached to the top surface of the guide rail. The arc on the outer surface of the top of the third slider fits onto the outer surface of the bottom end of the slide column, so that when the third slider bends during sliding, the bottom surface of the slide column limits its position, preventing excessive bending.

[0025] 3. The linear guide rail straightening machine of the present invention places the guide rail into the inner surface of the guide rail holder and the mating clamping plate, rotates the threaded rod, and causes the mating clamping plate on the outer surface of the threaded rod to slide to one side, pushing and squeezing the guide rail to one end. With the help of the squeezing soft pad, some toothed tracks on both sides of the guide rail are softly squeezed to increase the contact force. The soft squeezing soft pad will not cause excessive squeezing damage to the guide rail on both sides of the guide rail. When the mating clamping plate slides, the position of the mating clamping plate is limited by the limiting rod, so that the mating clamping plate can move horizontally when sliding, without positional displacement, which would cause uneven surface contact of the guide rail and cause the surface of the guide rail to shift.

[0026] 4. In the linear guide straightening machine of the present invention, after the guide rail clamp fixes the two ends of the guide rail, the top surface of the guide rail will overlap and fit against the inner wall of the top of the straightening frame. As the slider 2 slides on the inner wall of the sliding rail, if a protrusion appears on the surface of the guide rail, the limiting telescopic plate will pull back the upward straightening plate, and the docking limiting rod on the top surface of the upward straightening plate will be sleeved onto the bottom surface of the straightening frame to fix it. The downward straightening plate will press down on the top surface of the guide rail to squeeze and restore some slightly protruding positions on the surface of the guide rail. If the bending is too large, the bottom upward straightening plate will no longer rise. Using the gap between the guide rail and the upward straightening plate, the position of the guide rail will be squeezed and shaped under the pressure of the downward straightening plate.

[0043] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0044] like Figures 1 to 7 As shown in the embodiment of the present invention, a linear guide straightening machine includes, when in use, the linear straightening machine provided by the present invention, comprising:

[0045] Guide rail clamps 12 are installed on the top of the machining table 11 and located at the left and right edges;

[0046] The guide rail 13 is movably sleeved on the inner wall of the guide rail holder 12;

[0047] Slider 2 14 is slidably sleeved on the inner wall of the machining table 11

[0048] Slider 2 14 includes a compression fine-tuning unit, which includes a fixed plate 1 144. Multiple threaded collars c1 are threadedly and movably sleeved on the outer surface of the fixed plate 1 144. A limiting sleeve c2 is fixedly connected to the inner wall of the threaded collars c1. V-shaped compression strips c21 are symmetrically and fixedly connected to the inner walls of the top of both sides of the limiting sleeve c2. A sliding column c25 is slidably sleeved on the inner wall of the limiting sleeve c2 and fixedly connected to the bottom surface of the V-shaped compression strip c21. An elastic wire c22 is fixedly connected to the top surface of the sliding column c25 and located at the periphery of the V-shaped compression strip c21. The other end of the elastic wire c22 is fixedly connected to the top inner wall of the limiting sleeve c2. A micro-elastic steel wire c26 is fixedly connected to the bottom surface of the sliding column c25. A slider 3 c27 is movably sleeved on the outer surface of the bottom end of the sliding column c25.

[0049] The upper inner walls of the two sides of the limiting sleeve c2 are symmetrically and fixedly connected with conductive wires c23, and the other end of conductive wire c23 is fixedly connected to the middle position of the outer side of the V-shaped extrusion strip c21. The upper inner middle position of the limiting sleeve c2 is fixedly connected with a current-carrying wire c24 set at the middle edge position of the two conductive wires c23.

[0050] The present invention provides a method in which a guide rail 13 is sleeved onto both ends of a guide rail holder 12 and pressed and fixed thereon. A second slider 14 slides from one end to the other on the surface of a processing table 11, while a third slider 27 slides against the top surface of the guide rail 13. When it encounters a protruding arc on the top surface of the guide rail 13, the protruding arc will press the third slider 27 upwards in the opposite direction. At this time, one end of a sliding column 25 is in contact with the inner wall of the third slider 27. The error clearance is within the normal range of the convex arc on the surface of the guide rail 13. When the slider three C27 slides past the normal value, under the reverse push of the micro-elastic steel wire C26, the slider three C27 is re-attached to the top surface of the guide rail 13. The arc on the outer surface of the top of the slider three C27 fits onto the outer surface of the bottom end of the slide column C25. When the slider three C27 slides, if it bends, the bottom end surface of the slide column C25 limits its position to avoid excessive bending.

[0051] When the bending amplitude on the top surface of the guide rail 13 exceeds the error gap, the slider 3c27 will pass through the error gap and directly press against the bottom surface of the slider c25. The slider c25 will move in the opposite direction at a vertical angle into the limiting sleeve c2, thus pressing the V-shaped extrusion strip c21. Under the bending and compression, the V-shaped extrusion strip c21, whose length remains unchanged, will fold in half, bringing it closer together. This will cause the conductive wire c23 on the surface between a21 to adhere to the surface of the energized wire c24. When the energized wire c24 and the conductive wire c23 adhere, electricity will be generated between them, triggering an alarm to the external controller and thus affecting the guide rail. The protruding arc on the surface of guide rail 13 is straightened by compression. As the bottom surface of slider 3 c27 continues to slide, it moves away from the arc on the top surface of guide rail 13. The arc on the bottom surface of slider 3 c27 no longer protrudes. Under the reverse compression of elastic wire c22, the sliding column c25 is squeezed downward from the inside of the limiting sleeve c2. At the same time, the inner wall of the limiting sleeve c2 pushes the sliding column c25 at a vertical downward angle. When the sliding column c25 slides down, it pulls the V-shaped extrusion strip c21. The V-shaped extrusion strip c21 is stretched and the angle expands, causing the conductive wire c23 on the surface of the V-shaped extrusion strip c21 to fall off the surface of the current-carrying wire c24, thereby turning off the alarm.

[0052] Furthermore, such as Figure 5 - Figure 7 As shown, a conductive wire C3 is fixedly installed at the top center of the limiting sleeve C2, which is located on one end of the energizing wire C24. A fixing plate C4 is fixedly connected to one end of the conductive wire C3, and an indicator light C5 is fixedly installed on one side edge of the top of the fixing plate C4. One end of the conductive wire C3 is linearly connected to the linear receiving end of the indicator light C5.

[0053] When the limiting sleeve c2 and the indicator light c5 provided by the present invention are used, they work together to detect and control the different degrees of protrusion curvature on the top surface of the guide rail 13. If the curvature on the top surface of the guide rail 13 is too large, the inside of the limiting sleeve c2 will be energized, and the power will pass through the conductive wire c3 to energize the inside of the indicator light c5. The illuminated indicator light c5 will position the guide rail 13 on the top surface, thereby pressing down and straightening the top surface of the guide rail 13.

[0054] Furthermore, such as Figure 1 and 4 - Figure 6As shown, a straightening frame 141 is fixedly connected to the outer surface of the fixed plate 144 and is disposed on the outer surface of the slider 14. A support rod 142 is fixedly connected to the top surface of the straightening frame 141 and located at the four corners. A downward straightening plate 143 is fixedly installed on the inner wall of the top of the support rod 142 and located in the middle position. One end of the downward straightening plate 143 passes through the inner wall of the straightening frame 141 and movably overlaps the top outer surface of the guide rail 13. Limiting telescopic plates 145 are symmetrically fixedly connected to both sides of the straightening frame 141. An upward straightening plate 146 is fixedly installed at the bottom inner edge of the limiting telescopic plate 145. A docking limiting rod 147 is fixedly installed on the top surface of the upward straightening plate 146 and located at the four edges. A sliding plate 148 is fixedly connected to the bottom surface of the upward straightening plate 146 and movably overlaps the top outer surface of the wear-resistant layer 112.

[0055] When the straightening frame 141, the upward straightening plate 146, the downward straightening plate 143, and the docking limiting rod 147 provided by this invention are in use, after the guide rail holder 12 fixes the two ends of the guide rail 13, the top surface of the guide rail 13 will overlap and fit against the inner side wall of the top of the straightening frame 141. As the slider 14 slides on the inner side wall of the sliding track 111, if a protrusion appears on the surface of the guide rail 13, the limiting telescopic plate 145 will pull back the upward straightening plate 146. The flat guide rail has upward and downward bending. During the test, the upward bending guide rail is pressed flat by downward pressing, and some downward bending guide rails are pulled upward by the upward straightening plate 146. If no downward bending guide rail is encountered, the bottom upper... The shifting correction plate 146 will not move upwards; its principle is the same as the downward pressing form. The docking limit rod 147 docks with the correction frame 141 when the shifting correction plate 146 moves upwards. Multiple docking limit rods 147 attach the docking limit rods 147 on the top surface of the shifting correction plate 146 to the bottom surface of the correction frame 141, fixing them in place. In conjunction with the downward pressing correction plate 143, the top surface of the guide rail 13 is pressed down, and some slightly protruding positions on the surface of the guide rail 13 are squeezed and restored. If the bending is too large, the bottom shifting correction plate 146 will no longer rise. Using the gap between the guide rail 13 and the shifting correction plate 146, the position of the guide rail 13 is squeezed and shaped under the pressure of the downward pressing correction plate 143.

[0056] Furthermore, such as Figure 1 - Figure 4As shown, a wear-resistant layer 112 is fixedly connected to the top surface of the processing table 11. A sliding rail 111 is fixedly connected to the inner wall of the processing table 11 at the top edge, and is movably sleeved on the outer surface of the slider 14. A groove is provided on the top surface of the processing table 11 at the middle of the bottom of the wear-resistant layer 112. A double-strand limiting rod 113 is fixedly connected to the inner wall of the groove. A slider 114 is slidably sleeved on the outer surface of the double-strand limiting rod 113 and slidably overlapped on the inner wall of the groove. Two sets of guide rail holders 12 are provided. One set of guide rail holders 12 is fixedly installed at the top edge of the wear-resistant layer 112. The bottom surface of the other set of guide rail holders 12 is fixedly installed on the top surface of the slider 114. The inner walls of the straightening frame 141 and the upward straightening plate 146 are movably sleeved on the outer surface of the guide rail 13.

[0057] When using the double-strand limiting rod 113 and slider 114 provided by the present invention, the slider 114 slides on the surface of the double-strand limiting rod 113, and the guide rail holder 12 on the top surface of the slider 114 is pulled and moved, so that guide rails 13 of different lengths can be adjusted, and the two ends of the guide rails 13 can be fixed in conjunction with the guide rail holder 12.

[0058] Furthermore, such as Figure 1 - Figure 3 As shown, a limiting rod a2 is fixedly connected to the inner wall of the guide rail holder 12 and located at the four corners. A mating clamping plate a1 is movably sleeved on the outer surface of the limiting rod a2 and overlaps the top outer surface of the wear-resistant layer 112. A compression soft pad a3 is fixedly connected to the inner surface of the guide rail holder 12 and the mating clamping plate a1 and adheres to the outer surface of the guide rail 13. A threaded rod a4 is movably sleeved on the bottom outer surface of the guide rail holder 12 and the outer surface of the threaded rod a4 is threaded onto the inner bottom wall of the mating clamping plate a1.

[0059] When using the limiting rod a2, docking clamping plate a1, compression pad a3, and threaded rod a4 provided by this invention, the guide rail 13 is placed into the guide rail holder 12 and the inner surface of the docking clamping plate a1. The threaded rod a4 is rotated, causing the docking clamping plate a1 on the outer surface of the threaded rod a4 to slide to one side, pushing and squeezing the guide rail 13 to one end. The compression pad a3, in conjunction with the compression pad a3, provides soft compression to some toothed tracks on both sides of the guide rail 13, increasing the contact force. When the docking clamping plate a1 slides, the limiting rod a2 limits the position of the docking clamping plate a1, allowing the docking clamping plate a1 to move horizontally without positional displacement. This prevents uneven surface contact of the guide rail 13 and avoids surface displacement of the guide rail 13.

[0060] The working principle provided by this invention is as follows: The guide rail 13 is placed on the inner surface of the guide rail holder 12 and the docking clamping plate a1. The threaded rod a4 is rotated, causing the docking clamping plate a1 on the outer surface of the threaded rod a4 to slide to one side, pushing and squeezing the guide rail 13 to one end. The squeezing pad a3 is used to softly squeeze some toothed tracks on both sides of the guide rail 13 to increase the contact force. The soft squeezing pad a3 will not cause excessive squeezing damage to the guide rails on both sides of the guide rail 13. When the docking clamping plate a1 slides, the position of the docking clamping plate a1 is limited by the limiting rod a2. When the docking clamping plate a1 slides, the limiting rod a2 and the threaded rod a4 allow the docking clamping plate a1 to move horizontally without displacement, which would cause uneven contact on the surface of the guide rail 13 and cause displacement on the surface of the guide rail 13.

[0061] Slider 2 14 slides from one end to the other on the surface of the processing table 11, while slider 3 c27 slides against the top surface of the guide rail 13. When it encounters the convex arc on the top surface of the guide rail 13, the convex arc on the top surface of the guide rail 13 will exert upward pressure on slider 3 c27 in the opposite direction. At this time, the error gap between one end of the sliding column c25 and the inner wall of slider 3 c27 is within the normal range of the convex arc on the surface of the guide rail 13. When slider 3 c27 slides past the normal value, under the reverse push of the micro-elastic steel wire c26, slider 3 c27... The slider 3 C27 is reattached to the top surface of the guide rail 13. The arc of the outer top surface of slider 3 C27 fits onto the outer bottom surface of the slide column C25. This allows slider 3 C27 to bend during sliding, and the bottom surface of the slide column C25 limits its position, preventing excessive bending. When the bending amplitude on the top surface of the guide rail 13 exceeds the error clearance, slider 3 C27 will pass through the error clearance and directly press against the bottom surface of the slide column C25. This causes the slide column C25 to move in the opposite direction at a vertical angle into the limiting sleeve C2, thereby... The V-shaped extrusion strip c21 is compressed, and the curvature on the surface of the V-shaped extrusion strip c21 remains unchanged under compression and bending. When folded in half, the V-shaped extrusion strip c21 is brought closer together, thereby adhering the conductive wire c23 on the surface between a21 to the surface of the energized wire c24. When the energized wire c24 and the conductive wire c23 are adhering, electricity is generated between them, thereby triggering an alarm to the external controller. This, in turn, straightens the convex curvature on the surface of the guide rail 13 by compression. As the slider c27 continues to slide down, the bottom surface of the guide rail 13 is exposed from the top surface. After the arc on the top moves away, the arc on the bottom surface of slider three c27 no longer protrudes. Under the reverse compression of elastic wire c22, the sliding column c25 is squeezed downward from the inside of the limiting sleeve c2. At the same time, the inner wall of the limiting sleeve c2 pushes the sliding column c25 at a vertical downward angle. When the sliding column c25 slides down, it pulls the V-shaped extrusion strip c21. The V-shaped extrusion strip c21 is stretched and the angle expands, causing the conductive wire c23 on the surface of the V-shaped extrusion strip c21 to fall off the surface of the current-carrying wire c24, thereby turning off the alarm.
