Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] As Figure 1, Figure 5 , Figure 6 , Figure 8 As shown in Figure 5 , Figure 6 , and Figure 8 , a device for detecting the parallelism of a cylinder guide groove according to the present invention includes a telescopic sleeve 1. An expansion and contraction structure 2 is provided inside the telescopic sleeve 1. Fine adjustment structures 4 are respectively connected to both ends of the expansion and contraction structure 2. A support structure 3 is provided in the middle of the expansion and contraction structure 2. An indicating structure 5 is connected to the bottom side of the fine adjustment structure 4. A reversing structure 6 is provided on the bottom side of the indicating structure 5. A locking structure 7 is connected between the indicating structure 5 and the fine adjustment structure 4.

[0034] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , and Figure 6 , the expansion and contraction structure 2 includes a reversing gear 203. The reversing gear 203 is rotatably connected to the middle of the telescopic sleeve 1. One rack 202 is meshed on each side of the reversing gear 203. The two racks 202 are arranged in parallel. The rack 202 is slidably connected to the inside of the telescopic sleeve 1. A fixed tooth block 208 is meshed on the side of the rack 202. The fixed tooth block 208 is slidably connected to the telescopic sleeve 1. A second elastic member 210 is fixedly connected between the fixed tooth block 208 and the telescopic sleeve 1. A resisting column 209 is provided at the top of the fixed tooth block 208. The resisting column 209 has a cylindrical structure. A traction slider 204 is slidably connected to the top side of the telescopic sleeve 1. An extrusion block 207 is fixedly connected to the side of the traction slider 204. The side of the resisting column 209 abuts against the extrusion block 207. There are two traction sliders 204. A first elastic member 206 is fixedly connected between the two traction sliders 204. A horizontal groove 205 is opened on the top side of the traction slider 204. A release rotary block 201 is rotatably connected to the top side of the telescopic sleeve 1. Two columnar structures are provided on the bottom side of the release rotary block 201. The columnar structures on the bottom side of the release rotary block 201 are slidably connected to the traction slider 204 through the horizontal groove 205;

[0035] There are two racks 202 disposed within the telescopic sleeve 1 that are simultaneously engaged with the reversing gear 203. By synchronously sliding the two racks 202 within the telescopic sleeve 1, the length of the device can be adjusted, thereby performing parallelism detection on cylinder guide grooves of different widths. When in use, the user needs to rotate the release knob 201. At this time, the cylindrical structure at the bottom side of the release knob 201 will slide within the transverse groove 205 at the top side of the traction slider 204, and simultaneously pull the two traction sliders 204 to slide towards the middle. At this time, the extrusion block 207 on the side of the traction slider 204 disengages from the contact post 209 at the top end of the fixed tooth block 208. Under the traction of the second elastic member 210, the end of the fixed tooth block 208 disengages from the meshing state with the same-side rack 202, enabling the user to freely slide the rack 202, thereby adjusting the measurement width. After the adjustment is completed, the release knob 201 is released, and the extrusion block 207 pushes the fixed tooth block 208 to re-engage with the rack 202. At this time, due to the blockage of the extrusion block 207, the fixed tooth block 208 will maintain the current position of the rack 202, thereby maintaining the current measurement length of the device, facilitating the parallelism detection of cylinder guides of different widths.

[0036] Specifically, as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12 As shown, the fine-tuning structure 4 includes a measuring base 401. The rack 202 has an "L" - shaped structure. The end of the rack 202 is slidably connected to the measuring base 401. The end of the rack 202 is rotatably connected to a driving screw 403. The inner side of the measuring base 401 is rotatably connected to a first bevel gear 404. The first bevel gear 404 is threadedly connected to the driving screw 403. The side of the first bevel gear 404 is engaged with a second bevel gear 405. The middle of the second bevel gear 405 is fixedly connected to an adjusting rod 402. The adjusting rod 402 is rotatably connected to the measuring base 401;

[0037] After the initial adjustment of the measurement width is completed through the telescopic effect of the rack 202, in order to further improve the accuracy of the adjustment, the user can rotate the adjusting rod 402 at the top of the measuring bases 401 at both ends. By driving the second bevel gear 405 to rotate through the first bevel gear 404, since the middle of the second bevel gear 405 is threadedly connected to the driving screw 403 and the measuring base 401 is slidably connected to the rack 202, as the driving screw 403 rotates, the extending length of the measuring base 401 can be further adjusted, improving the accuracy of the test.

[0038] Specifically, as Figure 1 , Figure 2, Figure 4 , Figure 6 As shown, the support structure 3 includes a support frame 301, the side of the telescopic sleeve 1 is slidably connected with the support frame 301, a third elastic member 303 is fixedly connected between the support frame 301 and the telescopic sleeve 1, a locking rod 304 is slidably connected to the inner side of the telescopic sleeve 1, a fourth elastic member 305 is fixedly connected between the locking rod 304 and the telescopic sleeve 1, one end of the locking rod 304 is in conflict with the fixed tooth block 208, a plurality of locking grooves 306 are provided on the side of the support frame 301, one end of the locking rod 304 away from the fixed tooth block 208 is engaged with the support frame 301 through the locking groove 306, and a plurality of first pulleys 302 are rotatably connected to the bottom side of the support frame 301;

[0039] A support frame 301 is provided on the side of the telescopic sleeve 1, and a third elastic member 303 is connected between the support frame 301 and the telescopic sleeve 1. When the user rotates the release rotary block 201, the fixed tooth block 208 slides. At this time, the locking rod 304 is disengaged from the support frame 301 under the traction of the fourth elastic member 305, so that the support frame 301 slides out to support the middle part of the telescopic sleeve 1. After the user completes the telescopic length adjustment of the rack 202, the release rotary block 201 is released. At this time, the tooth block position is restored, and then the locking rod 304 is pushed to re-engage with the locking groove 306 on the side of the support frame 301, thereby fixing the current support state of the support frame 301 and improving the stability of the support.

[0040] Specifically, Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the indicating structure 5 comprises an inspection plate 502, the bottom side of the measuring seat 401 is provided with an inspection plate 502, the bottom side of the measuring seat 401 is parallelly fixedly connected with two guide rods 504, the inspection plate 502 is slidably connected to the measuring seat 401 through the guide rods 504, the two sides of the inspection plate 502 are respectively fixedly connected to the measuring seat 401 with fifth elastic members 505, the inner side of the inspection plate 502 is rotatably connected with a rotating sleeve 503, the inner side of the measuring seat 401 is rotatably connected with an indicating rod 501, the bottom end of the indicating rod 501 is slidably connected with the rotating sleeve 503, the distance between the indicating rod 501 and the rotating sleeve 503 is less than the length of the indicating rod 501 in the measuring seat 401, the indicating rod 501 is in a "T"-shaped structure, and the top end of the indicating rod 501 is slidably connected with the measuring seat 401;

[0041] After the adjustment of the distance measured by the device, a detection plate 502 slides on the bottom side of the measurement seats 401 at both ends. The detection plate 502 slides along the guide rod 504. At the same time, fifth elastic members 505 are fixed between both sides of the detection plate 502 and the measurement seats 401, which are used to keep the detection plate 502 at the middle position of the measurement seats 401. When measuring the parallelism of the cylinder guide rail through the detection plate 502, if the detection plate 502 is offset, at this time, the rotating sleeve 503 inside the detection plate 502 will drive the indicating rod 501 to rotate. The length of the indicating rod 501 inside the measurement seat 401 is relatively large, so that a small offset at the bottom end of the indicating rod 501 will be displayed as a larger offset at the top side part, thus facilitating the operator to observe the parallelism and the degree of offset of the cylinder guide rail and improving the measurement accuracy.

[0042] Specifically, as Figure 5 , Figure 6 , Figure 7 , Figure 9 , Figure 11 , Figure 12 shown, the commutation structure 6 includes a commutation shaft 601. The bottom side of the detection plate 502 is rotatably connected to the commutation shaft 601. A plurality of second pulleys 603 are rotatably connected to the side surface of the commutation shaft 601. A first positioning groove 602 is formed in the middle of the commutation shaft 601. A release block 604 is slidably connected to the middle of the detection plate 502. A sixth elastic member 605 is fixedly connected between the release block 604 and the detection plate 502. The end of the release block 604 is engaged with the commutation shaft 601 through the first positioning groove 602. A plurality of second positioning grooves 606 are respectively formed at both ends of the commutation shaft 601. A positioning post 607 is slidably connected to the inside of the detection plate 502. A seventh elastic member 608 is fixedly connected between the positioning post 607 and the detection plate 502. The bottom end of the positioning post 607 is of a hemispherical structure. The spherical end of the positioning post 607 abuts against the commutation shaft 601 through the second positioning groove 606;

[0043] After the adjustment of the device, a plurality of pulleys are provided on the bottom side of the detection plate 502. By making the pulleys fit and roll on the measured surface, the accuracy of the test can be ensured. In order to adapt to different detection surfaces, the user can adjust the direction of the pulleys. Slide the release block 604 on the bottom side of the detection plate 502, so that the end of the release block 604 disengages from the first positioning groove 602 in the middle of the commutation shaft 601. Then rotate the commutation shaft 601. The positioning effect of the positioning post 607 and the second positioning groove 606 can ensure that the commutation shaft 601 rotates to the specified position. Then release the release block 604, and the angle of the current commutation shaft 601 can be fixed, so that the pulleys on the side surface of the commutation shaft 601 can fit the detection surface at different angles.

[0044] Specifically, as Figure 5 ,Figure 7 As shown, the locking structure 7 includes a locking rotating shaft 701. The locking rotating shaft 701 is rotatably connected to the side surface of the measuring base 401. A rotating groove 702 is formed inside the measuring base 401. The end of the locking rotating shaft 701 is rotatably connected to the measuring base 401 through the rotating groove 702. A clamping groove 703 is formed on the top side of the detection plate 502. The side surface of the locking rotating shaft 701 is clamped with the detection plate 502 through the clamping groove 703. A contact block 704 is rotatably connected to the end of the locking rotating shaft 701. An eighth elastic member 705 is fixedly connected between the contact block 704 and the measuring base 401;

[0045] After the direction of the reversing shaft 601 is adjusted, the user needs to fix the position of the detection plate 502 on one side and obtain the parallelism of the cylinder guide groove through the indicating rod 501 on the other side. Press and rotate the locking rotating shaft 701 on the side surface of the measuring base 401, so that the protruding part on the side surface of the locking rotating shaft 701 slides into the clamping groove 703 on the detection plate 502. At this time, the detection plate 502 and the measuring base 401 are relatively fixed, and the indicating rod 501 thereon is always located in the middle position. Then, the pulley on the side surface of the reversing shaft 601 on this side is attached to and slides on the measured surface, and the pulley on the other side is attached to and slides on another detection surface. At this time, observe whether the indicating rod 501 deflects to obtain the parallelism of the cylinder guide rail.

[0046] When the present invention is in use, first, there are two racks 202 disposed inside the telescopic sleeve 1 that are simultaneously engaged with the reversing gear 203. By the synchronous sliding of the two racks 202 inside the telescopic sleeve 1, the length of the device can be adjusted, and then the parallelism of the cylinder guide grooves with different widths can be detected. During use, the user needs to rotate the release knob 201. At this time, the cylindrical structure at the bottom side of the release knob 201 will slide in the transverse groove 205 at the top side of the traction slider 204, and at the same time, the two traction sliders 204 are pulled to slide towards the middle. At this time, the extrusion block 207 on the side of the traction slider 204 disengages from the contact post 209 at the top end of the fixed tooth block 208. Under the traction of the second elastic member 210, the end of the fixed tooth block 208 is disengaged from the meshing state with the rack 202 on the same side, enabling the user to freely slide the rack 202, and then adjust the measuring width. After the adjustment is completed, the release knob 201 is released, and the extrusion block 207 pushes the fixed tooth block 208 to re-engage with the rack 202. At this time, due to the blocking of the extrusion block 207, the fixed tooth block 208 will maintain the current position of the rack 202, thereby maintaining the current measuring length of the device, facilitating the parallelism detection of cylinder guides with different widths. After the preliminary adjustment of the measuring width is completed through the telescopic effect of the rack 202, in order to further improve the accuracy of the adjustment, the user can rotate the adjusting rod 402 at the top of the measuring seats 401 at both ends. The first bevel gear 404 drives the second bevel gear 405 to rotate. Since the middle of the second bevel gear 405 is threadedly connected to the driving screw 403, and the measuring seat 401 is slidably connected to the rack 202, the extending length of the measuring seat 401 can be further adjusted as the driving screw 403 rotates, improving the accuracy of the test. A support frame 301 is disposed on the side of the telescopic sleeve 1. A third elastic member 303 is connected between the support frame 301 and the telescopic sleeve 1. When the user rotates the release knob 201, the fixed tooth block 208 slides. At this time, the locking rod 304 is disengaged from the engaging state with the support frame 301 under the traction of the fourth elastic member 305, enabling the support frame 301 to slide out for supporting the middle of the telescopic sleeve 1. After the user completes the adjustment of the telescopic length of the rack 202 and releases the release knob 201, the position of the tooth block is restored at this time, and then the locking rod 304 is pushed to re-engage with the locking groove 306 on the side of the support frame 301, thereby fixing the current supporting state of the support frame 301 and improving the stability of the support. After the adjustment of the measuring distance of the device is completed, a detection plate 502 slides on the bottom side of the measuring seats 401 at both ends. The detection plate 502 slides along the guide rod 504. At the same time, fifth elastic members 505 are fixed between both sides of the detection plate 502 and the measuring seats 401 for keeping the detection plate 502 at the middle position of the measuring seats 401. When measuring the parallelism of the cylinder guide by the detection plate 502, if the detection plate 502 is offset, at this time, the rotating sleeve 503 inside the detection plate 502 will drive the indicating rod 501 to rotate. The length of the indicating rod 501 inside the measuring seat 401 is relatively large.A small offset at the bottom end of the indicating rod 501 will be displayed as a larger offset at the top side part, facilitating the operator to observe the parallelism and offset degree of the cylinder guide rail, improving the measurement accuracy. After the adjustment of the device is completed, a plurality of pulleys are provided on the bottom side of the detection plate 502. By making the pulleys fit and roll on the measured surface, the accuracy of the test can be ensured. In order to adapt to different detection surfaces, the user can adjust the direction of the pulleys. Slide the release block 604 located on the bottom side of the detection plate 502, so that the end of the release block 604 disengages from the first positioning groove 602 in the middle of the reversing shaft 601. Then rotate the reversing shaft 601. The positioning effect of the positioning post 607 and the second positioning groove 606 can ensure that the reversing shaft 601 rotates to the specified position. Then release the release block 604 to fix the angle of the current reversing shaft 601, so that the pulleys on the side of the reversing shaft 601 can fit the detection surface at different angles. After the direction of the reversing shaft 601 is adjusted, the user needs to fix the position of one side of the detection plate 502 and obtain the parallelism of the cylinder guide rail groove through the indicating rod 501 on the other side. Press and rotate the locking spindle 701 on the side of the measuring seat 401, so that the protruding part on the side of the locking spindle 701 slides into the engaging groove 703 on the detection plate 502. At this time, the detection plate 502 and the measuring seat 401 are relatively fixed, and the indicating rod 501 thereon is always located in the middle position. Then make the pulley on the side of the reversing shaft 601 on this side fit and slide on the measured surface, and the pulley on the other side fit and slide on another detection surface. At this time, observe whether the indicating rod 501 deflects to obtain the parallelism of the cylinder guide rail.
