Description

Technical Field

[0001] The invention relates to the technical field of equipment detection, and in particular to a rotation accuracy detection device for a dividing plate. Background Art

[0002] The indexing disk is a machine tool accessory that clamps the workpiece on the chuck or between the two centers and rotates, indexes and positions it. It is mostly used in automation equipment. According to its transmission and indexing form, it can be divided into worm pair indexing disk, disk indexing disk, hole disk indexing disk, slot disk indexing disk, end gear disk indexing disk and other indexing disks (including inductive indexing disk and grating indexing disk). According to its function, it can be divided into universal indexing disk, semi-universal indexing disk and other indexing disks. According to its structural form, there are vertical and horizontal indexing disks, tiltable indexing disks, and cantilevered indexing disks. As a general machine tool accessory, the structure of the indexing disk is mainly composed of a clamping part, an indexing and positioning part, and a transmission part. The indexing disk is mainly used in milling machines, and is also commonly used in drilling machines and surface grinders. It can also be placed on a platform for fitters to mark lines. There are two main types of indexing disks: universal indexing heads and optical indexing heads.

[0003] Since the dividing plate is a precision device and there will be tolerance gaps in the assembly of the dividing plate, the dividing plate needs to be tested for rotation accuracy before leaving the factory. The existing dividing plate detection uses a dial indicator. The contact of the dial indicator is placed on the outer wall of the dividing plate. The dividing plate is then rotated and the offset deviation detected by the contact is observed to determine whether the dividing plate is within the qualified factory standards.

[0004] However, in the actual inspection process of the existing inspection methods on the market, since the dividing plate is still in the process before leaving the factory, the inspectors are unaware of the rotational floating of the dividing plate at this time. If the contacts of the dial indicator are placed on the outer wall of the dividing plate for inspection at this time, the dividing plate with large floating may collide and damage the contacts of the dial indicator, thereby causing failure and damage. Secondly, the accuracy of the dial indicator is tested with a fixed accuracy, which makes it inconvenient for the inspectors to check the rotational accuracy of the dividing plate more carefully.

[0005] Therefore, it is necessary to provide a rotation accuracy detection device for a dividing plate to solve the above technical problems. Summary of the invention

In this way, after the measuring disk to be measured is just produced (it has not undergone any inspection, and the operator does not know whether the specific deviation is large or small), the first detection gear can be used to detect the accuracy first.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The invention provides a rotation accuracy detection device for a dividing plate.

[0047] First embodiment:

[0048] Please combine Figures 1 to 5 , a rotation accuracy detection device for a dividing plate, comprising a base plate 7, a detection mechanism 3 and a lifting mechanism 5;

[0049] A testing platform 1 is fixedly arranged on the upper surface of the bottom plate 7, and a dividing plate 2 to be tested is placed on the upper surface of the testing platform 1;

[0050] The detection mechanism 3 includes a mounting seat 31 fixedly mounted on the upper surface of the detection platform 1 and located on one side of the indexing plate 2 to be tested, a screw rod 32 is rotatably connected inside the mounting seat 31, a crank 310 is connected to the outer end keyway of the screw rod 32, a moving block 33 is threadedly connected to the outer wall of the screw rod 32, a slot plate 34 is fixedly mounted on the upper surface of the moving block 33, a slider 35 is slidably mounted on the top of the slot plate 34 by bolts, a sleeve 37 is fixedly mounted on the upper surface of the slider 35, a mounting plate 36 is fixedly mounted on the outer wall of the sleeve 37, a detection rod 38 is slidably connected inside the sleeve 37, and a reset spring 39 is sleeved on the outer wall of the detection rod 38;

[0051] A limiting groove 311 is provided inside the mounting plate 36, and a sliding frame 312 is slidably connected inside the limiting groove 311, and a positioning bolt 313 is threadedly connected inside the sliding frame 312, and a first detection gear 315 and a second detection gear 316 are rotatably connected to the upper surface of the sliding frame 312, and a fixing ring 317 is fixedly provided on the upper surface of the sliding frame 312 and directly above the first detection gear 315 and the second detection gear 316, and a first scale plate 318 and a second scale plate 319 are rotatably connected to the upper surfaces of the two fixing rings 317, and a first pointer 320 and a second pointer 321 are fixedly provided on the upper surfaces of the first detection gear 315 and the second detection gear 316, respectively, and a bidirectional rack 314 is fixedly provided at the tail end of the detection rod 38;

[0052] A side plate 9 is fixedly provided on the side of the detection platform 1 , and a propulsion cylinder 10 is installed on the upper surface of the side plate 9 . The output end of the propulsion cylinder 10 is bolted to the indexing plate 2 to be detected.

[0053] See also Figure 1 : First, the user needs to place the indexing plate 2 to be tested on the testing table 1. If the weight of the indexing plate 2 to be tested is heavy, the user can use a ceiling hanging device for auxiliary work.

[0054] See also Figure 2 : After the dividing plate 2 to be tested is placed, the user needs to rotate the crank 310 to control the screw 32 to rotate. The rotation of the screw 32 can drive the moving block 33 to control the entire mounting plate 36 and the sleeve 37 to move along the mounting seat 31. The detection rod 38 needs to be close to the outer wall of the dividing plate 2 to be tested.

[0055] See also Figure 3 and Figure 4 : Before testing, the measuring disk 2 to be tested needs to be divided into four points abcd according to ninety degrees. The front arc surface of the detection rod 38 needs to contact the point b. During the test, the user starts the measuring disk 2 to be tested to rotate. The measuring disk 2 to be tested rotates from point b to point a, point a to point d, point d to point c, and finally from point c to point b. If the measuring disk 2 to be tested is polarized during rotation, the polarized point will definitely be forced to resist the sliding of the detection rod 38 inside the sleeve 37. At this time, the two-way rack 314 will definitely be moved by the sliding of the detection rod 38 to engage and control the rotation of the first detection gear 315. When the first detection gear 315 rotates, it will control the rotation of the first pointer 320 above. The user can roughly judge the polarization error by observing which scale line the first pointer 320 rotates on the first scale plate 318, and judging the difference between the scale line and the starting scale on the first scale plate 318, and then make precision adjustment and control accuracy.

[0056] See also Figure 3 and Figure 5 : After the observation of the first scale plate 318 is completed, the user needs to slide the sliding frame 312 to separate the first detection gear 315 and the bidirectional rack 314. At this time, the second detection gear 316 is displaced and meshed with the bidirectional rack 314. Then the user needs to start the measured dividing plate 2. The measured dividing plate 2 rotates from point b to point a, point a to point d, point d to point c, and finally from point c to point b. The operation method is the same as the above. At this time, if polarization occurs, the bidirectional rack 314 will mesh to control the rotation of the second detection gear 316. The user can judge the accuracy deviation by observing the rotation position of the second pointer 321 on the second scale plate 319.

[0057] The moving block 33 is slidably connected to the mounting seat 31 . The cross section of the slider 35 is dovetail-shaped. Both ends of the reset spring 39 are fixedly connected to the sleeve 37 and the detection rod 38 , respectively.

[0058] The first detection gear 315 is meshed with one side of the bidirectional rack 314 , the second detection gear 316 is not in contact with the other side of the bidirectional rack 314 , and the bottom end of the positioning bolt 313 extends to the inner bottom of the limiting groove 311 .

[0059] See also Figure 3 : It can be understood that the user can freely rotate the first dial 318 and the second dial 319 on the fixed ring 317 in actual work, so that the initial scale positions on the first dial 318 and the second dial 319 can be rotated and adjusted to the positions indicated by the first pointer 320 and the second pointer 321 by manual adjustment during the detection process;

[0060] Furthermore, the limiting groove 311 is of a dovetail-shaped structure, so that the sliding frame 312 can be quickly locked when the positioning bolt 313 is rotated.

[0061] This embodiment: Compared with the traditional fixed-precision dial indicator design, this case is designed with a bidirectional rack 314, and the two sides of the bidirectional rack 314 are respectively adapted to the first detection gear 315 and the second detection gear 316. In this way, after the measured dividing plate 2 is just produced (it has not undergone any detection, and the operator does not know whether the specific deviation is large or small), the first detection gear 315 can be used to detect the accuracy first. Because the first detection gear 315 has a large pitch, if the rotation deviation of the measured dividing plate 2 is large, it can be quickly observed through the first detection gear 315, and the approximate accuracy can also be judged. After the first detection gear 315 is detected, it is detected by the second detection gear 316. Since the pitch of the second detection gear 316 is small, the detection value after the accuracy adjustment can be observed more carefully, and the accuracy can be adjusted by two detection methods with different pitches. Such a design can not only avoid the measured dividing plate 2 with large deviation from damaging the traditional dial indicator, but also can achieve one detection and one adjustment, thereby realizing the convenience and highest accuracy of the detection.

[0062] Second embodiment:

[0063] See also Figure 1 , Figures 6 to 8 A positioning plate 4 is fixedly provided on the top of the detection platform 1, and the lifting mechanism 5 includes a lifting cylinder 51 installed on the upper surface of the positioning plate 4, and a mounting barrel 52 is installed at the bottom end of the lifting cylinder 51. The inner walls of the mounting barrel 52 are respectively fixed with a first positioning plate 53 and a second positioning plate 54, and the inner middle position of the first positioning plate 53 is rotatably connected to a first gear 55 through a coil spring, and the first gear 55 is meshed with a first rack 56 on both sides, and the bottom ends of the two first racks 56 are fixed with a first pressure rod 57, and the inner middle position of the second positioning plate 54 is rotatably connected to a second gear 59 through a coil spring, and the second gear 59 is meshed with a second rack 510 on both sides, and the bottoms of the two second racks 510 are fixed with a second pressure rod 511, and the first positioning plate 53 and the second positioning plate 54 are both provided with a first avoidance groove 58 and a second avoidance groove 512.

[0064] See also Figure 1 and 6 : When the detection of the first embodiment is completed, the user needs to start the propulsion cylinder 10 to push the dividing plate 2 to be tested (in the first embodiment, the user can use bolts to connect the propulsion cylinder 10 and the outer wall of the dividing plate 2 to be tested after placing the dividing plate 2 to be tested), push the dividing plate 2 to be tested to the bottom close to the lifting mechanism 5, and the axis center of the dividing plate 2 to be tested needs to coincide with the axis center of the mounting barrel 52.

[0065] See also Figure 6 and Figure 8:The lifting cylinder 51 controls the installation barrel 52 to descend, and the two first pressure rods 57 and the two second pressure rods 511 will contact the four points abcd on the indexing disk 2 to be tested. As the descending force of the lifting cylinder 51 increases, if the left and right ends of the indexing disk 2 to be tested deviate, the second gear 59 at this time will rotate to drive the second racks 510 on both sides to control the second pressure rod 511 to keep descending synchronously with the deviation of the indexing disk 2 to be tested. If the left end of the indexing disk 2 to be tested descends, the right end will definitely rise, so that the second pressure rod 511 at the left end will definitely follow the decline, and the second pressure rod 511 at the right end will definitely rise;

[0066] Then the movement modes of the first pressing rod 57 and the second pressing rod 511 at the other two points are the same.

[0067] The first rack 56 is slidably connected to the first positioning plate 53 , the second rack 510 is slidably connected to the second positioning plate 54 , and the horizontal direction of the first avoidance groove 58 is 90 degrees to the direction of the second avoidance groove 512 .

[0068] See also Figure 6 and Figure 7 : A first avoidance groove 58 and a second avoidance groove 512 are provided, and such a configuration is to avoid the first pressure rod 57 and the second pressure rod 511 from interfering with the first positioning plate 53 and the second positioning plate 54 during the downward displacement process.

[0069] In this embodiment: pressure is applied to the four points abcd on the measuring disk 2 to be tested by the first pressure rod 57 and the second pressure rod 511 (simulating the load-bearing force of the measuring disk 2 to be tested during actual use), and once the measuring disk 2 to be tested has a force deviation, the two first pressure rods 57 and the two second pressure rods 511 will move according to the deviation value to maintain continuous contact with the surface of the measuring disk 2 to be tested. Therefore, such a lifting cylinder 51 can apply equal force to the four points on the measuring disk 2 to be tested, thereby ensuring the accuracy of force loading. Compared with the traditional loading method, such equal force application is more meaningful in the detection process, and is more convenient for users to perform secondary detection and adjustment. At the same time, it can also well protect the various connection positions of the measuring disk 2 to be tested (such as the turntable position and the connection between the internal servo motor).

[0070] Third embodiment:

[0071] See also Figure 1 , Fig. 9 and Fig.11, also includes a cleaning mechanism 6, the cleaning mechanism 6 includes a slide 61 embedded in the upper surface of the detection platform 1, two magnetic blocks 62 are fixedly provided on the outer wall of the slide 61, a first stable groove 63 and a second stable groove 64 are opened on the side wall of the detection platform 1, a third gear 65 and a fourth gear 66 are rotatably connected between the first stable groove 63 and the second stable groove 64 on the side wall of the detection platform 1, a trigger rack 67 is slidably connected in the first stable groove 63, a cleaning rack 68 is slidably connected in the second stable groove 64, a mounting rod 69 is fixedly provided on the outer wall of the cleaning rack 68, and a cleaning roller 610 is rotatably connected to the outer end of the mounting rod 69.

[0072] The third gear 65 and the fourth gear 66 are meshed with each other, the top of the third gear 65 is meshed with the bottom of the trigger rack 67, the bottom of the fourth gear 66 is meshed with the top of the cleaning rack 68, the outer wall of the cleaning roller 610 is in contact with the upper surface of the detection platform 1, and one end of the slide 61 is fixedly connected to the trigger rack 67.

[0073] See also Fig. 9 : In the first embodiment, the cleaning roller 610 is in the initial state, and the indexing plate 2 to be measured is not yet connected to the magnetic block 62.

[0074] See also Fig.10 : When switching from the first embodiment to the second embodiment, the measuring disc 2 to be measured will be attracted to the magnetic block 62 during its displacement. At this time, the movement of the measuring disc 2 to be measured will drive the magnetic block 62 to control the synchronous movement of the slide 61 to control the trigger rack 67 to engage and control the third gear 65 to engage and drive the fourth gear 66 to rotate, so that the cleaning rack 68 will move synchronously with the movement of the magnetic block 62, so that the cleaning roller 610 can clean the fitting area between the measuring disc 2 to be measured and the detection table 1.

[0075] It also includes a cleaning mechanism 8, which includes a placement frame 81 installed on the upper surface of the test platform 1, a water bag 84 is installed inside the placement frame 81, and a liquid infusion tube 85 and a hose 82 are fixed on both sides of the water bag 84, a spring pressure plate 86 is slidably connected inside the placement frame 81 and located on the outer wall of the water bag 84, and a nozzle 83 is fixed on the upper surface of the side plate 9 and located on both sides of the propulsion cylinder 10;

[0076] The hose 82 is installed in a sealing manner with the nozzle 83 .

[0077] See also Fig.10 and Fig.11: When the second embodiment is switched, the slide 61 will be forced to resist the spring pressure plate 86 to control the water bag 84 inside the placement rack 81 to be compressed. When the water bag 84 is compressed, the internal medium (the medium can be alcohol or diesel, etc.) will be sprayed on the inspection table 1 after cleaning through the hose 82 on the nozzle 83. Finally, after the loading and force application work is completed, if a second inspection is required, the cleaning roller 610 can be cleaned again.

[0078] In this embodiment: when switching from the initial rotation accuracy to the gravity loading, the measured dividing disk 2 in the displacement process will drive the movement of the magnetic block 62 to control the cleaning roller 610 to clean the contact position between the detection platform 1 and the measured dividing disk 2. After that, when the switching is completed, the medium will be sprayed on the detection platform 1 that has been cleaned once through the nozzle 83. Then, when the gravity loading is completed, it is necessary to drive the measured dividing disk 2 back to the rotation detection process. The cleaning roller 610 can also perform secondary cleaning on the medium contact on the detection platform 1. This design ensures the cleanliness of the detection platform 1, can avoid other factors such as oil stains that affect the rotation accuracy detection of the measured dividing disk 2, and the method of cleaning first and then cleaning can ensure the optimization of the cleaning effect.

[0079] Please refer to Figures 1 to 11 The working principle of the rotation accuracy detection device for the indexing plate provided by the present invention is as follows:

[0080] Step S1: First, the user needs to place the dividing plate 2 to be tested on the testing table 1. If the weight of the dividing plate 2 to be tested is large, the user can choose a ceiling hanging device for auxiliary work. After the dividing plate 2 to be tested is placed, the user needs to rotate the crank 310 to control the screw 32 to rotate. The rotation of the screw 32 can drive the moving block 33 to control the entire mounting plate 36 and the sleeve 37 to move along the mounting seat 31. The detection rod 38 needs to be close to the outer wall of the dividing plate 2 to be tested. Before testing, the dividing plate 2 to be tested needs to be divided into four points abcd according to ninety degrees. The front arc surface of the detection rod 38 needs to contact point b. During testing, the user starts the rotation of the dividing plate 2 to be tested. The dividing plate 2 to be tested rotates from point b to point a, point a to point d, point d to point c, and finally from point c to point b. If polarization occurs during rotation of the measured dividing disk 2, the polarization point will certainly be subjected to force to resist the sliding of the detection rod 38 inside the sleeve 37. At this time, the two-way rack 314 will certainly be affected by the sliding of the detection rod 38 and move to engage and control the rotation of the first detection gear 315. When the first detection gear 315 rotates, it will control the rotation of the first pointer 320 above. The user can roughly judge the polarization error by observing which scale line the first pointer 320 rotates on the first dial 318 and judging the difference between the scale line and the starting scale on the first dial 318. When adjusting the accuracy and controlling the accuracy, the operation method is the same as the above. At this time, if polarization occurs, the two-way rack 314 will engage and control the rotation of the second detection gear 316. The user can judge the accuracy deviation by observing the rotation position of the second pointer 321 on the second dial 319.

[0081] Step S2: During the displacement of the indexing disc 2 to be tested, it will be attracted to the magnetic block 62. At this time, the movement of the indexing disc 2 to be tested will drive the magnetic block 62 to control the slide 61 to move synchronously, control the trigger rack 67 to engage and control the third gear 65 to engage and drive the fourth gear 66 to rotate, so that the cleaning rack 68 will move synchronously with the movement of the magnetic block 62, so that the cleaning roller 610 can clean the fitting part of the indexing disc 2 to be tested and the test platform 1, and the slide 61 will be forced to resist the spring pressure plate 86 to control the water bag 84 inside the placement frame 81 to be compressed. When the water bag 84 is compressed, the internal medium (the medium can be alcohol or diesel, etc.) will be sprayed on the test platform 1 after cleaning through the hose 82 on the nozzle 83. Finally, after the loading and force application work is completed, if a second inspection is required, the cleaning roller 610 can be cleaned again.
