Description

Technical Field

[0001] This invention relates to the field of gauges, and more specifically, to a gauge for measuring complex groove-shaped convertible references. Background Technology

[0002] With the continuous development of technology, automated machinery is widely used in product manufacturing and processing. Linear guides can achieve linear reciprocating motion and high-precision linear motion under high loads. Linear guides are commonly used in automated machinery to achieve high-precision machining of products. Both ends of the slider of the linear guide are equipped with sealed end caps. The end caps can prevent foreign objects from entering the linear guide and ensure its normal operation. The end caps have grooves that correspond to the cross-sectional shape of the guide to prevent the end caps from affecting the operation of the linear guide. Whether the size of the groove is appropriate is one of the factors affecting the quality of the linear guide. If the size of the groove is too large, the sealing effect of the end cap is poor, and foreign objects can easily enter the linear guide, thus affecting its operation. If the size of the groove is too small, the end cap will contact the guide, hindering the slider from moving on the guide, thus affecting the operation of the linear guide. Therefore, it is necessary to inspect the size of the groove on the end cap and screen out unqualified end caps for reprocessing.

[0003] However, the shape of the end cap groove is relatively complex, and it is inconvenient to measure the size of the groove using common measuring tools, making it impossible to accurately judge whether the end cap is qualified. Summary of the Invention

[0004] This invention provides a gauge for measuring complex groove shapes using convertible references, solving the technical problem in related technologies where the shape of the end cap groove is complex, making it inconvenient to measure the size of the groove using common measuring tools, and thus making it impossible to accurately judge whether the end cap is qualified.

[0005] According to one aspect of the present invention, a gauge for measuring complex groove-shaped convertible references is provided, comprising a base, a clamping mechanism on the base for fixing an end cap to be inspected, a position adjustment mechanism connected below the base, a detection mechanism connected to the top of the position adjustment mechanism, the position adjustment mechanism for adjusting the position of the detection mechanism so that the detection mechanism can detect the size of the end cap groove, and a conversion mechanism connected to the detection mechanism for converting the data obtained by the detection mechanism from the end cap groove size measurement, which is difficult to judge, into data that can be directly judged as to whether the end cap groove size meets the requirements.

[0006] The detection mechanism includes rack one, a locking pin, a limiting plate, a detection plate, a positioning plate, a pin, and rack two. Rack one is slidably connected to the position adjustment mechanism. A locking groove is opened on the side of rack one away from its tooth groove, and a locking pin is engaged in the groove. The locking pin is slidably connected to the position adjustment mechanism. When the locking pin is inserted into the locking groove, rack one cannot slide relative to the adjustment mechanism. When the locking pin slides out of the locking groove, rack one can slide relative to the adjustment mechanism. A limiting plate is fixedly connected to the end of rack one near the clamping mechanism. The limiting plate has a sliding groove on the side near the clamping mechanism. The detection plate is slidably connected to the sliding groove. A positioning plate is fixedly connected to the top of the detection plate. The positioning plate has a pin hole that extends into the limiting plate. A pin is inserted into the pin hole. When the pin is inserted into the pin hole, the detection plate cannot slide along the sliding groove. When the pin leaves the pin hole, the detection plate can slide along the sliding groove. Rack two is fixedly connected to the top of the positioning plate on the side near the limiting plate.

[0007] Furthermore, the shape of the detection plate is consistent with the cross-sectional shape of the guide rail that matches the end cap to be tested, so as to determine whether the size of the end cap groove meets the requirements by the range of movement of the detection plate within the end cap groove.

[0008] Furthermore, the length direction of rack one is consistent with the axial direction of the detection plate, so as to judge whether the dimension in the axial direction of the end cover groove meets the requirements by the length of the sliding of rack one relative to the adjustment mechanism.

[0009] Furthermore, the length direction of the slide groove is parallel to the horizontal plane and perpendicular to the length direction of rack one. The length direction of rack two is consistent with the length direction of the slide groove. Thus, the length of the sliding of rack two relative to the adjustment mechanism is used to judge whether the dimension of the end cover groove perpendicular to the axis meets the requirements.

[0010] Furthermore, the conversion mechanism includes a conversion assembly, dial one, and dial two. The conversion assembly has two sets, including gear one, shaft one, gear two, shaft two, and pointers. One set of gear one meshes with rack one, and the other set of gear one meshes with rack two. Gear one has shaft one, and gear one is rotatably sleeved with shaft one. Gear one meshes with gear two, and gear two has shaft two, and gear two is fixedly sleeved with shaft two. The pointer is fixedly sleeved on the outer ring of the top of shaft two. Dial one is rotatably sleeved on the outer ring of the top of shaft two near rack one, and dial two is rotatably sleeved on the outer ring of shaft two near rack two. The two sets of pointers are located inside dial one and dial two, respectively.

[0011] Furthermore, dial one has a zero mark, a minimum limit mark, and a maximum limit mark. Before testing begins, the pointer inside dial one points to the zero mark. During testing, the pointer inside dial one deflects.

[0012] Furthermore, the second dial has a zero mark, a minimum limit mark, and a maximum limit mark. Both the minimum and maximum limit marks have two sets. The two sets of minimum limit marks are symmetrically arranged about the zero mark, and the two sets of maximum limit marks are symmetrically arranged about the zero mark. When the pin is inserted into the pin hole, the pointer inside the second dial points to the zero mark. During the testing process, the pointer inside the second dial deflects.

[0013] Furthermore, gear two has fewer teeth than gear one, thereby appropriately amplifying the data detected by the testing mechanism to make more accurate judgments and improve the reliability and accuracy of the test results.

[0014] Furthermore, the position adjustment mechanism includes an adjustment plate, a lead screw, guide posts, a connecting plate, and a support plate. The adjustment plate has a through groove, and the part of the adjustment plate with the through groove is slidably connected to the base. The lead screw is rotatably sleeved at the end of the adjustment plate near the through groove. The part of the lead screw extending into the through groove has threads, and the lead screw is threadedly sleeved with the base. Two sets of vertically arranged guide posts are fixedly connected above the end of the adjustment plate away from the through groove. The two sets of guide posts are slidably sleeved with the same connecting plate. The connecting plate is slidably connected to a rack and pinion. The two sets of guide posts are fixedly sleeved with the same support plate, which is located below the connecting plate and is used to support the connecting plate. When the bottom surface of the connecting plate is in contact with the top surface of the support plate, the detection plate is located in the groove of the end cap.

[0015] Furthermore, the clamping mechanism includes a clamping part, a connecting rod, a sliding plate, a positioning shaft, and a return spring. The clamping part is slidably connected to the base. Both the clamping part and the connecting rod have two sets. The two sets of clamping parts are used to clamp the two ends of the end cap to be tested, thereby fixing the end cap to be tested. The two sets of clamping parts are rotatably sleeved with one end of the two sets of connecting rods, and the other end of the two sets of connecting rods is rotatably sleeved with the positioning shaft. The positioning shaft is fixedly installed on the sliding plate. The sliding plate is slidably connected to the base. During the process of the sliding plate driving the positioning shaft to move, the axis of the positioning shaft is always in the same plane as the plane of symmetry of the detection plate when the pin is inserted into the pin hole. The clamping part has a clamping surface, which is parallel to the plane of symmetry of the detection plate. When the two ends of the end cap are in contact with the two sets of clamping surfaces, the plane of symmetry of the end cap coincides with the plane of symmetry of the detection plate when the pin is inserted into the pin hole. The sliding plate is connected to the base through the return spring.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. In this invention, the shape of the detection plate is consistent with the cross-sectional shape of the guide rail that matches the end cap to be tested. The range of movement of the detection plate in the end cap groove is used to judge whether the size of the end cap groove meets the requirements. This can accurately judge whether the end cap is qualified and improve the rationality of the inspection tool.

[0018] 2. This invention converts the distance the detection plate moves within the end cap groove into the angle of pointer rotation. The size of the end cap groove can be directly judged by the scales on dial one and dial two and the position of the pointer, making the results more intuitive and easier to judge.

[0019] 3. The present invention uses gear one and gear two to mesh, and gear two has fewer teeth than gear one, to appropriately amplify the minute results of the detection, thereby improving the accuracy of the detection results. Attached Figure Description

Detailed Implementation

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0031] Example:

[0032] like Figures 1-8 As shown, a gauge for measuring complex groove-shaped convertible reference includes a base 1, a clamping mechanism 2 on the base 1 for fixing the end cap to be inspected, a position adjustment mechanism 3 connected below the base 1, and a detection mechanism 4 connected to the top of the position adjustment mechanism 3 for adjusting the position of the detection mechanism 4 so that the detection mechanism 4 can detect the size of the end cap groove. The detection mechanism 4 is connected to a conversion mechanism 5 for converting the data obtained by the detection mechanism 4 from detecting the size of the end cap groove, which is not easy to judge, into data that can be directly judged to determine whether the size of the end cap groove meets the requirements.

[0033] The detection mechanism 4 includes a first rack 41, a locking pin 42, a limiting plate 43, a detection plate 44, a positioning plate 45, a pin 46, and a second rack 47. The first rack 41 is slidably connected to the position adjustment mechanism 3. A slot 411 is provided on the side of the first rack 41 away from its tooth groove. The locking pin 42 is engaged in the slot 411. The locking pin 42 is slidably connected to the position adjustment mechanism 3. When the locking pin 42 is inserted into the slot 411, the first rack 41 cannot slide relative to the adjustment mechanism 3. When the locking pin 42 slides out of the slot 411, the first rack 41 can slide relative to the adjustment mechanism 3. The end of the first rack 41 is closer to the clamping mechanism 2. A limiting plate 43 is fixedly connected. The limiting plate 43 has a groove 431 on the side near the clamping mechanism 2. The detection plate 44 is slidably connected to the groove 431. A positioning plate 45 is fixedly connected to the top of the detection plate 44. The positioning plate 45 has a pin hole 451 that extends into the limiting plate 43. A pin 46 is inserted into the pin hole 451. When the pin 46 is inserted into the pin hole 451, the detection plate 44 cannot slide along the groove 431. When the pin 46 leaves the pin hole 451, the detection plate 44 can slide along the groove 431. A rack 47 is fixedly connected to the top of the positioning plate 45 on the side near the limiting plate 43.

[0034] In this embodiment, a pull ring is fixedly connected to the end of the rack 41 away from the limiting plate 43, so as to facilitate pulling the rack 41.

[0035] In this embodiment, the locking pin 42 is fixedly connected to the push plate 1, thereby facilitating the adjustment of whether the locking pin 42 is inserted into the card slot 411.

[0036] In this embodiment, a U-shaped mounting plate is fixedly installed above the limiting plate 43, and an L-shaped connecting rod is fixedly connected above the pin 46. A push plate is fixedly connected to the end of the connecting rod away from the clamping mechanism 2. The push plate is slidably connected to the mounting plate. Pushing the push plate causes the connecting rod and the pin 46 to move, thereby controlling whether the pin 46 is inserted into the pin hole 451.

[0037] The shape of the detection plate 44 is consistent with the cross-sectional shape of the guide rail that matches the end cover to be tested, so as to determine whether the size of the end cover groove meets the requirements by the range of movement of the detection plate 44 in the end cover groove.

[0038] The length direction of rack 41 is consistent with the axial direction of detection plate 44, so the length of the sliding of rack 41 relative to adjustment mechanism 3 is used to judge whether the dimension in the axial direction of end cover groove meets the requirements.

[0039] The length direction of the slide groove 431 is parallel to the horizontal plane, and the length direction of the slide groove 431 is perpendicular to the length direction of the rack 41. The length direction of the rack 47 is consistent with the length direction of the slide groove 431. Thus, the length of the rack 47 sliding relative to the adjustment mechanism 3 is used to judge whether the dimension of the end cover groove perpendicular to the axis meets the requirements.

[0040] The conversion mechanism 5 includes a conversion assembly 51, a first dial 52, and a second dial 53. The conversion assembly 51 has two sets, each including a first gear 511, a first rotating shaft 512, a second gear 513, a second rotating shaft 514, and a pointer 515. One set of first gears 511 meshes with a first rack 41, and the other set of first gears 511 meshes with a second rack 47. Each first gear 511 has a first rotating shaft 512, and the first gear 511 and the first rotating shaft 512 are rotatably engaged. Gear 511 meshes with gear 513. Gear 513 has a rotating shaft 514, and gear 513 is fixedly sleeved with rotating shaft 514. A pointer 515 is fixedly sleeved on the top outer ring of rotating shaft 514. A dial 52 is rotatably sleeved on the top outer ring of rotating shaft 514 near rack 41. A dial 53 is rotatably sleeved on the top outer ring of rotating shaft 514 near rack 47. The two sets of pointers 515 are located inside dial 52 and dial 53, respectively.

[0041] In this embodiment, the first rotating shaft 512 near the second rack 47 is fixedly connected to the first mounting plate, the second rotating shaft 514 near the second rack 47 is rotatably sleeved with the first mounting plate, and the second dial 53 is fixedly installed on the upper surface of the first mounting plate.

[0042] Dial 52 has a zero mark 521, a minimum limit mark 522, and a maximum limit mark 523. When the test is not started, the pointer 515 inside dial 52 points to the zero mark 521. During the test, the pointer 515 inside dial 52 deflects.

[0043] Dial 2 53 has a zero mark 2 531, a minimum limit mark 2 532, and a maximum limit mark 2 533. There are two sets of both the minimum limit mark 2 532 and the maximum limit mark 2 533. The two sets of minimum limit marks 2 532 are symmetrically arranged about the zero mark 2 531, and the two sets of maximum limit marks 2 533 are symmetrically arranged about the zero mark 2 531. When the pin 46 is inserted into the pin hole 451, the pointer 515 in dial 2 53 points to the zero mark 2 531. During the test, the pointer 515 in dial 2 53 deflects.

[0044] The number of teeth in gear 2 513 is less than that in gear 1 511, thereby appropriately amplifying the data detected by the detection mechanism 4 to make more accurate judgments and improve the reliability and accuracy of the detection results.

[0045] The position adjustment mechanism 3 includes an adjustment plate 31, a lead screw 32, guide posts 33, a connecting plate 34, and a support plate 35. The adjustment plate 31 has a through groove 311, and the part of the adjustment plate 31 with the through groove 311 is slidably connected to the base 1. The lead screw 32 is rotatably sleeved at the end of the adjustment plate 31 near the through groove 311. The part of the lead screw 32 that extends into the through groove 311 has threads, and the lead screw 32 is threadedly sleeved with the base 1. Two sets of vertically arranged guide posts 33 are fixedly connected above the end of the adjustment plate 31 away from the through groove 311. The two sets of guide posts 33 are slidably sleeved with the same connecting plate 34. The connecting plate 34 is slidably connected to the rack 41 and the locking pin 42. The two sets of guide posts 33 are fixedly sleeved with the same support plate 35. The support plate 35 is located below the connecting plate 34 and is used to support the connecting plate 34. When the bottom surface of the connecting plate 34 is in contact with the top surface of the support plate 35, the detection plate 44 is located in the groove of the end cap.

[0046] In this embodiment, a second mounting plate is fixedly connected to the upper side of the connecting plate 34 away from the limiting plate 43. A first rotating shaft 512 near the first rack 41 is fixedly connected to the second mounting plate. A second rotating shaft 514 near the first rack 41 is rotatably sleeved with the second mounting plate. A first dial 52 is fixedly installed on the upper surface of the second mounting plate.

[0047] In this embodiment, an anti-slip sleeve is fixedly fitted to the outer ring of one end of the lead screw 32 extending out of the adjustment plate 31, so that the lead screw 32 can be rotated by rotating the anti-slip sleeve.

[0048] In this embodiment, a U-shaped support guide plate is provided below the adjustment plate 31. The support guide plate is fixedly connected to the base 1 and slidably connected to the adjustment plate 31. The support guide plate can support and guide the movement of the adjustment plate 31, preventing the accuracy of the detection from being affected by the bending and deformation of the adjustment plate 31.

[0049] The clamping mechanism 2 includes a clamping part 21, a connecting rod 22, a sliding plate 23, a positioning shaft 24, and a return spring 25. The clamping part 21 is slidably connected to the base 1. Both the clamping part 21 and the connecting rod 22 have two sets. The two sets of clamping parts 21 are used to clamp the two ends of the end cap to be tested, thereby fixing the end cap to be tested. The two sets of clamping parts 21 are rotatably sleeved with one end of the two sets of connecting rods 22, and the other end of the two sets of connecting rods 22 are rotatably sleeved with the positioning shaft 24. The positioning shaft 24 is fixedly installed on the sliding plate 23. Sliding connection with base 1, during the sliding motion of slide plate 23 driving positioning shaft 24 to move, the axis of positioning shaft 24 is always in the same plane as the plane of symmetry of detection plate 44 when pin 46 is inserted into pin hole 451. Clamping part 21 has clamping surface 211, which is parallel to the plane of symmetry of detection plate 44. When the two ends of end cover are in contact with the two sets of clamping surfaces 211, the plane of symmetry of end cover coincides with the plane of symmetry of detection plate 44 when pin 46 is inserted into pin hole 451. Slide plate 23 is connected to base 1 through return spring 25.

[0050] In this embodiment, the clamping part 21 includes a support plate, a clamping plate, a baffle, a pressure plate, a threaded rod, and a fastening sleeve. The support plate is slidably connected to the base. An installation groove is provided on the side of the support plate near the connecting rod 22. A rotating shaft is installed in the installation groove and is rotatably sleeved with the connecting rod 22. Two sets of clamping plates are fixedly connected to the top of the support plate. The clamping plates have clamping surfaces 211. A baffle is fixedly connected to the top of the support plate. The baffle is perpendicular to the clamping plates and is located on the side of the clamping plates near the connecting rod 22. The baffle is located on the side of the connecting rod 22 near the limiting plate 43. The two sets of clamping plates are slidably sleeved with the same pressure plate. The pressure plate is fixedly sleeved with a threaded rod. The bottom outer ring of the threaded rod has threads. The threaded rod is threadedly sleeved with the support plate. A fastening sleeve is provided below the support plate and threadedly sleeved with the threaded rod. After the surface of the end cover is in contact with the support plate, clamping plate and baffle respectively, the fastening sleeve is turned to drive the threaded rod to move down, thereby driving the pressure plate to move down until the pressure plate is in close contact with the surface of the end cover, thereby fastening the end cover.

[0051] In this embodiment, the base includes a base plate and a mounting plate three. The mounting plate three is fixedly mounted on the base plate and is perpendicular to the base plate. The mounting plate three has a sliding groove one, a sliding groove two, a through groove one, and a fixing plate. The sliding groove one is parallel to the base plate and is slidably connected to the support plate. The sliding groove two is perpendicular to the sliding groove one and is slidably connected to the sliding plate 23. The through groove one has two sets, and both sets of through groove one are slidably connected to the adjusting plate 31. The fixing plate is located directly above the through groove one, and a return spring 25 is connected between the fixing plate and the sliding plate 23.

[0052] This embodiment proposes a gauge for measuring complex groove-shaped convertible references. The testing method is as follows: Press down the positioning shaft 24, slide the slide plate 23 downward, stretch the return spring 25, and rotate the two sets of connecting rods 22 around the positioning shaft 24 during the downward movement, thereby driving the two sets of clamping parts 21 to move away from each other. Place the end cap to be tested between the two sets of clamping parts 21, so that the end cap is close to the clamping part 21. Release the positioning shaft 24, shorten the return spring 25, and drive the slide plate 23 and the positioning shaft 24 to move upward, thereby driving the connecting rod 22 to move. The movement of the connecting rod 22 drives the two sets of clamping parts 21 to move closer to each other until the clamping surface 211 of the clamping part 21 is in contact with the end cap. Adjust the clamping part 21 to make the clamping part 21 secure the end cap.

[0053] Slide the connecting plate 34 downwards, causing the detection mechanism 4 and the conversion mechanism 5 to move down synchronously. At the same time, rotate the lead screw 32 to adjust the position of the position adjustment mechanism 3, causing the detection mechanism 4 and the conversion mechanism 5 to move, so that the detection plate 44 falls into the groove of the end cap. The lower surface of the connecting plate 34 is in contact with the upper surface of the support plate 35. Then continue to rotate the lead screw 32, causing the position adjustment mechanism 3, the detection mechanism 4 and the conversion mechanism 5 to move towards the clamping mechanism 2 until the detection plate 44 touches the inner wall of the groove of the end cap.

[0054] Push the locking pin 42 away from the rack 41, causing the locking pin 42 to slide out of the slot 411. Then pull the rack 41 away from the clamping mechanism 2. The movement of the rack 41 drives the corresponding gear 511 to rotate, thereby driving the gear 513 to rotate, which in turn drives the rotating shaft 514 and the pointer 515 to rotate synchronously. When the rack 41 is pulled to its limit position (the rack 41 can no longer be pulled away from the clamping mechanism 2), observe the area where the pointer 515 is located in the dial 52 and record the result. Then push the rack 41 towards the clamping mechanism 2 and push the locking pin 42 back into the slot 411.

[0055] Rotate the lead screw 32 to move the position adjustment mechanism 3, the detection mechanism 4, and the conversion mechanism 5 away from the clamping mechanism 2 until the detection plate 44 can slide the maximum distance in the end cover groove when sliding along the slide groove 431. Pull the pin 46 away from the positioning plate 45 until the pin 46 slides out of the pin hole 451. Push the detection plate 44 to slide along the slide groove 431 to the maximum distance on both sides. The sliding of the detection plate 44 drives the positioning plate 45 and the rack 47 to move synchronously. The movement of the rack 47 drives the corresponding gear 511 to rotate, thereby driving the gear 513 to rotate, which in turn drives the rotating shaft 514 and the pointer 515 to rotate synchronously. When the rack 47 slides to the limit position (the detection plate 44 slides to the maximum distance), observe the area where the pointer 515 is located in the dial 53 and record the two results. Then push the detection plate 44 and push the pin 46 back into the pin hole 451.

[0056] If the pointer 515 in dial 1 52 falls between the minimum limit scale 1 522 and the maximum limit scale 1 523, and the pointer 515 in dial 2 53 falls between the minimum limit scale 2 532 and the maximum limit scale 2 533 twice, the groove size of the end cover meets the requirements. Otherwise, the groove size of the end cover does not meet the requirements and needs to be reprocessed.

[0057] The embodiments of this embodiment have been described above with reference to the accompanying drawings. However, this embodiment is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this embodiment without departing from the spirit of this embodiment and the scope of protection of the claims, and all of these forms are within the protection scope of this embodiment.
