Description

Technical Field

[0001] This application relates to the technical field of detection equipment, and particularly to a guide rail hole pitch detection equipment. Background Art

[0002] A guide rail is a device used to guide and support moving components to perform linear or rotary motion along a specific trajectory. The guide rail is usually made of metal or other materials, has a groove or ridge shape, is used to bear, fix, and guide the moving device or equipment, and reduce the friction it receives; usually, a plurality of through holes are provided on the guide rail, and the plurality of through holes are arranged in an array along the length direction of the guide rail. The detection equipment detects the hole pitch between two adjacent through holes on the guide rail to determine whether the spacing accuracy of the through holes opened on the guide rail meets the requirements.

[0003] In the related art, the detection equipment includes a base and a detection structure. The detection structure is arranged on the base, and the detection structure can detect the guide rail.

[0004] The detection equipment usually does not detect all guide rails. When the manufacturer produces guide rails, sampling detection is carried out, and some guide rails are selected for detection. Since the guide rail itself is relatively long, placing the base requires a large amount of space. The detection equipment has a single function and is not commonly used in normal times, so the applicability of the detection equipment needs to be increased. Summary of the Invention

[0005] In order to improve the problem of the single function of the detection equipment, this application provides a guide rail hole pitch detection equipment.

[0006] A guide rail hole pitch detection equipment provided by this application adopts the following technical scheme:

[0007] A guide rail hole pitch detection equipment includes a base, a detection structure, and a marking structure. The detection structure and the marking structure are both arranged on the base. The marking structure is used to mark the guide rail. A pushing member for positioning the guide rail is provided on the base. A moving structure is provided on the base, and the moving structure is used to drive the detection structure and the marking structure to move along the length direction of the guide rail.

[0008] By adopting the above technical scheme, the pushing member abuts against the guide rail to position the guide rail on the base. In addition, the moving structure moves through the detection structure and the marking structure, so that the marking structure can mark the guide rail, and at the same time, the detection structure can detect the through holes in the guide rail, enabling the detection structure and the marking structure to occupy the same space. Thus, the detection equipment has the function of marking. Since the manufacturer usually needs to mark all guide rails, detection can be carried out when marking a certain part of the guide rails. One device can have two different functions, enabling the detection equipment to be frequently used and increasing the applicability of the detection equipment.

[0009] Optionally, a support frame is provided on the base, and a plurality of support plates are provided on the support frame. The pushing member includes a pushing cylinder and a pushing plate, and the pushing cylinder pushes the guide rail to abut against the support plate through the pushing plate.

[0010] By adopting the above technical solution, the pushing cylinder pushes the guide rail to abut against the support plate through the pushing plate, so that both sides of the guide rail are fixed, enabling the guide rail to be stably located on the support frame, and preventing the guide rail from moving during the detection of the detection structure, which may cause detection errors.

[0011] Optionally, a support block is detachably connected to the support frame, and the support block is located between two adjacent support plates.

[0012] By adopting the above technical solution, since the support block is located between two adjacent support plates, the support block can support the guide rail, enabling the guide rail between two adjacent support plates to be more stably detected, and avoiding the problem that the guide rail between two adjacent support plates is damaged due to the insertion of the detection structure.

[0013] Optionally, the moving structure includes a moving driving member and a moving rack. The moving rack is arranged on the base. A detection seat is provided on the base. A moving seat is slidably connected to the detection seat. The detection structure is arranged on the moving seat. The moving driving member is arranged on the detection seat. A moving gear for meshing with the moving rack is provided on the moving driving member, and the moving driving member is used to drive the moving gear to rotate.

[0014] By adopting the above technical solution, when the moving driving member rotates, the moving driving member drives the moving gear to rotate. In addition, since the moving gear and the moving rack mesh with each other, the moving gear can move along the moving rack, enabling the detection seat to move. When the detection structure detects the guide rail, if there is an error in the distance between two adjacent through holes in the guide rail, the insertion rod of the detection structure needs to be inserted into the through hole. At this time, the insertion rod of the detection structure may move slightly. Since the moving seat is slidably connected to the detection seat, the moving seat can move automatically, enabling the detection structure to stably detect the guide rail.

[0015] Optionally, a moving bar is provided on the moving seat, a linkage gear is provided on the moving driving member, a linkage rack for meshing with the linkage gear is slidably connected to the detection seat, and a return component for driving the linkage rack to reset is provided on the detection seat; when the linkage gear rotates, the linkage rack abuts against the moving bar, and at this time the moving seat is fixed to the detection seat; when the linkage rack resets, the linkage rack does not abut against the moving bar.

[0016] By adopting the above technical solution, when the moving driving member rotates, the moving driving member rotates through the linkage gear, and the linkage gear meshes with the linkage rack, enabling the linkage rack to abut against the moving bar, so that the linkage rack can stably restrict the movement of the moving seat. When the detection seat moves, the moving seat will not move, preventing relative movement between the moving seat and the detection seat during the movement of the detection seat, which may cause errors in the detection structure, and further improving the accuracy of the detection structure for detecting the guide rail; when the moving driving member does not rotate, the return component drives the linkage rack to reset, so that the linkage rack does not abut against the moving bar, enabling the moving seat and the detection seat to resume the function of relative movement, facilitating the need for the detection structure to move during the detection process.

[0017] Optionally, the return component includes a first magnet, a second magnet, and a third magnet. The first magnet and the third magnet are both arranged on the detection seat, the second magnet is arranged on the linkage rack, the first magnet and the third magnet both repel the second magnet, and the first magnet and the third magnet are respectively arranged on both sides of the second magnet; when the first magnet repels the second magnet, the linkage rack does not abut against the moving bar, and at this time the linkage rack can fall; when the third magnet repels the second magnet, the linkage rack meshes with the linkage gear.

[0018] By adopting the above technical solution, the first magnet repels the second magnet, separating the linkage rack from the moving bar. At this time, the linkage rack does not abut against the moving bar, enabling the moving seat and the detection seat to move relatively; then the linkage rack can fall, and in addition, the third magnet repels the second magnet, enabling the linkage rack to reset and the linkage rack to mesh with the linkage gear, facilitating the subsequent movement of the linkage rack driven by the linkage gear.

[0019] Optionally, a fixed spring is arranged on the detection seat, a fixed bar is arranged on the fixed spring, a fixed inclined surface is formed on the fixed bar, the fixed inclined surface is located on the moving path of the linkage rack, the fixed spring drives the fixed bar to move towards the moving bar, and the fixed bar does not abut against the moving bar; when the linkage gear abuts against the moving bar, the fixed spring drives the linkage rack to abut against the moving bar.

[0020] By adopting the above technical solution, since the fixed inclined surface is located on the moving path of the linkage rack, the linkage rack drives the fixed bar to move through the fixed inclined surface. At this time, the fixed spring drives the fixed bar to abut against the linkage rack, enabling the linkage rack to abut against the moving bar, so that the linkage rack can abut against the moving bar more stably, enabling the moving seat and the detection seat to be relatively fixed, and further reducing the possibility of movement of the moving seat and the detection seat.

[0021] Optionally, a limiting plate is slidably connected to the support frame. The limiting plate is located on the path where the guide rail disengages from the base. A limiting strip is provided on the linkage rack. When the detection structure detects the last perforation of the guide rail, the limiting strip drives the limiting plate to move, and at this time, the guide rail can disengage from the base.

[0022] By adopting the above technical solution, when the detection structure detects the last perforation of the guide rail, the linkage rack moves through the retracting assembly, so that the limiting strip can drive the limiting plate to move, making the limiting plate move away from the path where the guide rail disengages from the base, facilitating the disengagement of the guide rail from the base; by having the limiting plate located on the path where the guide rail disengages from the base, the guide rail is not easily disengaged from the base, so that the guide rail can be more stably located on the base, and the detection structure is not easily driven to move the guide rail during the detection process.

[0023] Optionally, a limiting spring is provided on the support frame. The limiting spring is arranged on the limiting plate, and the limiting spring drives the limiting plate to abut against one end of the guide rail.

[0024] By adopting the above technical solution, the limiting spring drives the limiting plate to abut against one end of the guide rail, so that the limiting plate can more stably limit the movement of the guide rail, making the limiting plate not easily fall due to vibration, and further enabling the limiting plate to stably limit the movement of the guide rail.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The pushing member drives the limiting plate to abut against the guide rail, enabling the guide rail to be fixed on the base. In addition, the moving structure moves through the detection structure and the marking structure, allowing the marking structure to mark the guide rail, and at the same time, the detection structure can detect the perforations in the guide rail, enabling the detection structure and the marking structure to occupy the same space, so that the detection device has the function of marking. Since manufacturers usually need to mark all guide rails, when marking a certain part of the guide rails, detection can be carried out, enabling a device to have two different functions, making the detection device be used frequently and increasing the applicability of the detection device.

[0027] 2. When the moving driving member rotates, the moving driving member rotates through the linkage gear, and the linkage gear meshes with the linkage rack, enabling the linkage rack to abut against the moving bar, so that the linkage rack can stably restrict the movement of the moving seat. When the detection seat moves, the moving seat will not move, preventing relative movement between the moving seat and the detection seat during the movement of the detection seat, which may cause errors in the detection structure, and further improving the accuracy of the detection structure for detecting the guide rail; when the moving driving member does not rotate, the linkage rack is driven to reset by the retracting component, so that the linkage rack does not abut against the moving bar, allowing the moving seat and the detection seat to resume the function of relative movement, facilitating the need for the detection structure to move during the detection process.

[0040] Embodiment 1

[0041] This embodiment discloses a rail hole pitch detection device. Refer to Figure 1 and Figure 2 , a rail hole pitch detection device, including a base 1, a detection structure 2 and a marking structure 3. A support frame 11 is fixedly connected to the base 1, and the support frame 11 extends along the length direction of the base 1. The detection structure 2 is used to detect the distance between two adjacent through holes in the rail; the marking structure 3 is used to mark the rail. Both the detection structure 2 and the marking structure 3 are slidably connected to the base 1.

[0042] Refer to Figure 2, a plurality of mounting plates 12 and a plurality of pushing members 13 are fixedly connected to the support frame 11. The pushing members 13 include a pushing cylinder 131 and a pushing plate 132. The plurality of mounting plates 12 are arranged in an array along the length direction of the support frame 11, and the pushing members 13 are arranged in an array along the length direction of the support frame 11. A support plate 121 is fixedly connected to the mounting plate 12, and the support plate 121 extends in the vertical direction. The pushing plate 132 is fixedly connected to the driving shaft of the pushing cylinder 131. The pushing cylinder 131 drives the pushing plate 132 to move towards the support plate 121, so that both sides of the guide rail abut against the support plate 121 and the pushing plate 132, realizing the fixation of the guide rail on the base 1.

[0043] Refer to Figure 2 , a plurality of support blocks 14 are threadedly connected to the support frame 11. The support blocks 14 are located between two adjacent mounting plates 12. The surface of the support block 14 away from the support frame 11 and the surface of the mounting plate 12 away from the support frame 11 are coplanar. When the guide rail is located on the mounting plate 12, the guide rail abuts against the mounting plate 12 and the support block 14.

[0044] Refer to Figure 2 , a plurality of rotating rods 15 are rotatably connected to the base 1. The plurality of rotating rods 15 are arranged in an array along the length direction of the base 1. The guide rail is placed on the rotating rods 15 to facilitate the movement of the guide rail after the marking structure 3 finishes marking the guide rail.

[0045] Refer to Figure 2 and Figure 3 , a moving structure 4 is provided on both the detection structure 2 and the marking structure 3. The moving structure 4 is used to move the detection structure 2 or the marking structure 3. The moving structure 4 includes a moving driving member 41 and a moving rack 42. The moving rack 42 is fixedly connected to the base 1. The moving driving member 41 is fixedly connected to the marking structure 3. The moving driving member 41 includes a moving motor. A moving gear 43 is fixedly connected to the driving shaft of the moving motor. The moving gear 43 is meshed with the moving rack 42.

[0046] Refer to Figure 3 , a sliding bar 17 is fixedly connected to the base 1. The sliding bar 17 extends along the length direction of the base 1. Both the detection structure 2 and the marking structure 3 are fixedly connected with a sliding seat 171. A sliding hole 172 for the sliding bar 17 to pass through is provided on the sliding seat 171. When the moving motor is started, the sliding seat 171 can move along the length direction of the sliding bar 17. When the staff drives the sliding seat 171 to move, the detection seat 5 can move along the length direction of the sliding bar 17.

[0047] Refer to Figure 4, the detection structure 2 includes a detection component 21 and a grating 22. The grating 22 is fixedly connected to the detection component 21, and the detection component 21 is fixedly connected to the sliding seat 171. When the detection component 21 detects the perforations in the guide rail, the grating 22 can record the moving distance to facilitate the measurement of the distance between adjacent perforations in the guide rail.

[0048] Refer to Figure 3 , the marking structure 3 includes a laser printer 31 and a marking body 32. The laser printer 31 is arranged on the marking body 32. The laser printer 31 can perform laser printing on the guide rail, and the marking body 32 can control the pattern printed by the mechanism printer.

[0049] The implementation principle of Embodiment 1 is: when the moving motor is started, the moving motor rotates through the moving gear 43, and the moving gear 43 moves on the moving rack 42 to realize the movement of the detection structure 2 or the marking structure 3 on the base 1.

[0050] Embodiment 2

[0051] Refer to Figure 5 and Figure 6 , the difference between this embodiment and Embodiment 1 is that a detection seat 5 is slidably connected to the base 1, a moving seat 51 is slidably connected to the detection seat 5, and the detection structure 2 is fixedly connected to the moving seat 51.

[0052] Refer to Figure 7 , a moving hole 52 is formed in the detection seat 5, and the moving hole 52 extends along the length direction of the base 1. A moving bar 511 is fixedly connected to the moving seat 51, and the moving bar 511 slides in the moving hole 52.

[0053] Refer to Figure 6 and Figure 7 , an installation block 53 is fixedly connected to the detection seat 5. A receiving hole 531 is formed in the installation block 53. The receiving hole 531 communicates with the moving hole 52, and the receiving hole 531 is for the moving bar 511 to be inserted. A linkage gear 54 is rotatably connected to the installation block 53. A first rotating gear 431 is fixedly connected to the moving gear 43. A second rotating gear 432 is meshed with the first rotating gear 431, and the second rotating gear 432 and the first rotating gear 431 are perpendicular to each other. The second rotating gear 432 and the linkage gear 54 rotate coaxially, so that the moving gear 43 can drive the linkage gear 54 to rotate through the first rotating gear 431 and the second rotating gear 432.

[0054] Refer to Figure 7, a linkage rack 541 is slidably connected to the mounting block 53. The linkage rack 541 extends along the length direction of the moving hole 52 and meshes with the linkage gear 54. When the moving gear 43 rotates, the moving gear 43 drives the linkage gear 54 to rotate, causing the linkage gear 54 to drive the linkage rack 541 to rotate.

[0055] Refer to Figure 7 , a mounting spring 532 is fixedly connected to the mounting block 53. A mounting strip 533 is fixedly connected to the surface of the mounting spring 532 away from the ground. The mounting strip 533 is slidably connected to the end face of the linkage rack 541. A linkage strip 542 is fixedly connected to the linkage rack 541, and the linkage strip 542 can abut against the moving strip 511. When the linkage strip 542 abuts against the moving strip 511, the mounting spring 532 is in a stretched state. When the linkage gear 54 does not rotate and the linkage rack 541 meshes with the linkage gear 54, the mounting spring 532 is in a non-loaded state.

[0056] Refer to Figure 7 and Figure 8 , a placement block 55 is fixedly connected to the detection base 5. The placement block 55 extends in the vertical direction. One side of the moving strip 511 abuts against the placement block 55, and the other side of the moving strip 511 can abut against the linkage strip 542, so that the moving strip 511 is fixed by the placement block 55 and the linkage strip 542.

[0057] Refer to Figure 7 and Figure 8 , a return assembly 6 is provided on the detection base 5. The return assembly 6 is used to reset the linkage gear 54. The return assembly 6 includes a first magnet 61, a second magnet 62, and a third magnet 63. A first magnetic attraction groove 64 is formed on the placement block 55, and the first magnet 61 is fixedly connected to the first magnetic attraction groove 64. A moving groove 521 is formed on the hole wall of the moving hole 52 for the linkage rack 541 to move. A third magnetic attraction groove 66 is formed on the bottom wall of the moving groove 521, and the third magnet 63 is fixedly connected to the third magnetic attraction groove 66. A second magnetic attraction hole 65 is formed on the linkage strip 542 and extends along the direction perpendicular to the length of the linkage strip 542, and the second magnet 62 is fixedly connected to the second magnetic attraction hole 65.

[0058] Refer to Figure 6 and Figure 7, when the detection base 5 starts to move, the linkage gear 54 rotates, driving the linkage rack 541 to move. At this time, the linkage bar 542 can abut against the moving bar 511, restricting the movement of the moving bar 511 and achieving relative fixation between the moving base 51 and the detection base 5 until the second magnet 62 abuts against the first magnet 61, causing the first magnet 61 to repel the second magnet 62. At this time, the linkage bar 542 and the moving bar 511 separate, enabling the moving bar 511 to move on the detection base 5. Also, the linkage rack 541 and the linkage gear 54 separate, causing the linkage rack 541 to fall under the tension of the mounting spring 532 and its own gravity until the third magnet 63 repels the second magnet 62, making the linkage rack 541 engage with the linkage gear 54. At this time, the linkage bar 542 resets.

[0059] Refer to Figure 7 and Figure 9 , on the wall of the moving groove 521, there is a receiving groove 522, and a fixing spring 523 is provided in the receiving groove 522. One end of the fixing spring 523 is fixedly connected to the bottom wall of the receiving groove 522, and the other end of the fixing spring 523 is fixedly connected to a fixing bar 524. The fixing bar 524 can be inserted into the receiving hole 531, and the fixing spring 523 drives the fixing bar 524 to protrude from the receiving groove 522. When the fixing bar 524 abuts against the moving bar 511, the fixing spring 523 is in a stretched state; when the fixing spring 523 is in a non-loaded state, the fixing bar 524 does not abut against the moving bar 511.

[0060] Refer to Figure 9 , on the surface of the fixing bar 524 away from the fixing spring 523, there is a fixing inclined surface 525. The distance between the fixing inclined surface 525 and the receiving groove 522 gradually decreases along the direction from the moving hole 52 to the receiving hole 531, and the fixing inclined surface 525 is located on the moving path of the linkage bar 542.

[0061] Refer to Figure 7 and Figure 9 , when the linkage gear 54 drives the linkage rack 541 to move, the linkage bar 542 drives the fixing bar 524 to move towards the fixing spring 523 through the fixing inclined surface 525, compressing the fixing spring 523. As a result, the fixing spring 523 exerts a force on the moving bar 511 through the fixing bar 524 on the linkage bar 542. At this time, the linkage bar 542 can abut against the moving bar 511, enabling the moving bar 511 and the linkage bar 542 to be fixed to each other, reducing the possibility of the moving bar 511 sliding in the moving hole 52.

[0062] Refer to Figure 10, a limiting block 16 is slidably connected to the support frame 11. A fastening bolt 161 is provided on the limiting block 16, and the fastening bolt 161 can be threadedly connected to the limiting block 16 to realize the mutual fixation of the limiting block 16 and the support frame 11. A limiting spring 162 is fixedly connected to the limiting block 16, and a limiting plate 163 is fixedly connected to the surface of the limiting spring 162 away from the limiting block 16. A limiting inclined surface 166 is formed on the surface of the limiting plate 163 facing the guide rail, and the distance between the limiting inclined surface 166 and the limiting spring 162 gradually increases along the sliding direction of the guide rail.

[0063] Referring to Figure 10 , when the limiting spring 162 is in a non-loaded state, the limiting plate 163 is located on the path where the guide rail disengages from the base 1. At this time, the guide rail abuts against the limiting plate 163, and the limiting inclined surface 166 is not on the moving path of the guide rail. When the limiting spring 162 is in a compressed state, the limiting plate 163 drops. At this time, the limiting inclined surface 166 is located on the sliding path of the guide rail, and the guide rail can drive the limiting plate 163 to move in the direction of the ground along the limiting inclined surface 166, so that the limiting plate 163 is not on the path where the guide rail disengages from the base 1, facilitating the disengagement of the guide rail from the base 1.

[0064] Referring to Figure 10 , a limiting strip 164 is fixedly connected to the linkage rack 541, and the limiting strip 164 extends along the length direction of the guide rail. A through hole 165 communicating with the moving hole 52 is formed in the fixed block. The through hole 165 extends in the vertical direction, and the through hole 165 allows the limiting strip 164 to slide. A driving block 167 is fixedly connected to the limiting plate 163, and the driving block 167 is located on the moving path of the limiting strip 164.

[0065] Referring to Figure 7 and Figure 10 , when the detection structure 2 detects the last perforation of the guide rail, the first magnet 61 repels the third magnet 63, so that the linkage bar 542 does not abut against the moving bar 511, causing the linkage gear 54 to fall under the tension of the mounting spring 532 and its own gravity. At this time, the driving block 167 is located on the moving path of the limiting strip 164, enabling the limiting strip 164 to drive the limiting plate 163 to move, realizing that the limiting plate 163 does not abut against the guide rail. At this time, the limiting spring 162 is in a compressed state.

[0066] The implementation principle of Embodiment 2 is as follows: The moving gear 43 rotates, causing the moving gear 43 to drive the linkage gear 54 to rotate. The linkage gear 54 drives the linkage rack 541 to move until the first magnet 61 repels the second magnet 62, separating the linkage bar 542 from the moving bar 511. At this time, the detection structure 2 conducts detection, and the linkage rack 541 is driven to fall under the tension of the mounting spring 532 and its own gravity until the third magnet 63 repels the second magnet 62, causing the linkage rack 541 to engage with the linkage gear 54. At this time, the linkage bar 542 is reset.
