Obviously, the implementation regulations described 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.

A first unidirectional screw rod 106 and a first bidirectional screw rod 107 are connected, and a first motor 108 and a second motor 109 are symmetrically installed on the outer surface of one side of the frame 101 near the edge. The outer surface of the first bidirectional screw rod 107 movably passes through the second sliding table 103 and is threaded through the two first sliding tables 102. The driving component 4 includes a second mounting frame 402 and two first mounting frames 401. The two first mounting frames 401 are respectively fixedly connected to the bottom of the two first sliding tables 102, and the second mounting frame 402 is fixedly connected to the bottom of one of the first sliding tables 102. The number of mounting components 5 is set to three, and the three mounting components 5 are respectively arranged between the inner surface walls of the three mounting holes 105.

[0024] The mounting assembly 5 includes a positioning column 501, which is rotatably connected between the inner surface walls of the mounting hole 105 through a bearing, and the outer surface of the positioning column 501 is fixedly connected to a limiting protrusion 502, and a plane bearing 511 is sleeved on the outer surface of the positioning column 501 below the limiting protrusion 502, wherein two plane bearings 511 are respectively mounted on the tops of the two first sliding tables 102, and another plane bearing 511 is mounted on the top of the second sliding table 103, and the output ends of the first motor 108 and the second motor 109 are both rotated to penetrate the outer surface of the frame 101, and the output end of the second motor 109 and the first bidirectional screw rod 1 One end of 07 is fixedly connected. When in use, the positioning holes at the centers of the three precision gears can be passed through the three positioning columns 501. During the process, the spline grooves in the positioning holes of the precision gears are aligned with the limiting protrusions 502 on the surfaces of the positioning columns 501. In the initial state of the positioning columns 501 at the tops of the two first sliding tables 102, the limiting protrusions 502 on the surfaces are in inconsistent directions and correspond to the positions of the spline grooves of the precision gears after the meshing state. Therefore, the two precision gears after installation will be in a meshing state when they are close to each other. Starting the second motor 109 to drive the first bidirectional screw 107 to rotate can drive the two first sliding tables 102 to move away from each other synchronously.

[0025] The positions of the outer surfaces of the opposite sides of the two first mounting frames 401 near the bottom are rotatably connected with the first bevel gears 403 through bearings, the positions of the outer surfaces of the two first bevel gears 403 near the top are meshed and connected with the second bevel gears 404, and the two second bevel gears 404 are respectively mounted on the bottom ends of two of the positioning columns 501, and a third motor 409 is mounted on the bottom of the second mounting frame 402, and the output end of the third motor 409 rotates through the outer surface of the second mounting frame 402 and is fixedly connected to the bottom center of one of the second bevel gears 404, a transmission sleeve 405 is fixedly connected to the outer surface of one of the first bevel gears 403, and a transmission rod 407 is fixedly connected to the outer surface of the other first bevel gear 403, the transmission sleeve 405 is slidably sleeved on the outside of the transmission rod 407 and a plurality of limit grooves 406 are equidistantly provided on the surface, a plurality of limit blocks 408 are equidistantly fixedly connected to the position of the outer surface of the transmission rod 407 near the transmission sleeve 405, and the appearance of the limit blocks 408 When the first bevel gear 403 rotates, the transmission rod 407 is driven to rotate, and the limit block 408 and the limit groove 406 cooperate to limit the transmission rod 407 and the transmission sleeve 405. Therefore, when the transmission rod 407 rotates, the other first bevel gear 403 and the second bevel gear 404 are driven to rotate. At this time, the two second bevel gears 404 will drive the positioning posts 501 on the two first sliding platforms 102 to rotate, and the two precision gears on the surface of the first sliding platform 102 that are in meshing state with each other will be in an active rotation state. During the process, the precision gear in the middle position will drive the precision gear above the second sliding platform 103 to rotate, while the precision gear above the second sliding platform 103 is in a passive rotation state.

[0026] The detection component 3 includes a connecting shell 301, and a third slide groove 302 is provided on the front surface of the connecting shell 301. Three sliding rods 304 extending toward the front side are slidably connected between the inner surface walls of the third slide groove 302. A micrometer 305 is installed at the front end of the sliding rod 304. A rectangular sleeve 306 is fixedly connected to the bottom of the sliding rod 304 near the rear side. A rectangular rod 307 extending downward is slidably connected between the inner surface walls of the rectangular sleeve 306. A third slider 308 is fixedly connected to the bottom of the rectangular rod 307. The first slide groove 104 is provided at the top of the first slide table 102 and the second slide table 103 near the rear side. The three third sliders 308 are slidably installed in the inside of the three first slide grooves 104 respectively. When in use, during the rotation of the precision gear, The detection head of the micrometer 305 is in contact with the surface of the precision gear, and the first electric push rod 204 will drive the micrometer 305 to move linearly forward and backward through the connecting shell 301 and the sliding rod 304 after extension and retraction. During the process, the micrometer 305 will continuously detect the displacement changes of different positions on the surface of the precision gear in a dynamic state, so as to judge the stability performance of the precision gear according to the displacement changes. The sliding rod 304 is slidably connected by the third sliding groove 302, so it can slide linearly left and right. The third sliding block 308 is slidably connected with the first sliding groove 104, so it can drive the rectangular rod 307 to move linearly forward and backward. The rectangular sleeve 306 and the rectangular rod 307 are slidably connected. Therefore, when the sliding rod 304 is raised or lowered, the rectangular sleeve 306 and the rectangular rod 307 will slide against each other and be in a sleeved state.

[0027] The adjusting assembly 2 includes a back plate 201, which is fixedly connected to the rear surface of the frame 101. A longitudinal second slide groove 202 is provided near the middle of the outer surface of the back plate 201. A first slider 203 is slidably connected between the inner surface walls of the second slide groove 202. A first electric push rod 204 is installed on the rear surface of the first slider 203. The telescopic end of the first electric push rod 204 slides through the outer surface of the first slider 203 and is fixedly connected to the rear surface of the connecting shell 301. A second electric push rod 205 is installed on the top of the back plate 201. The telescopic end of the second electric push rod 205 slides through the top of the back plate 201 and extends downward. The telescopic end of the second electric push rod 205 is fixedly connected to a sliding sleeve 206. The top of the connecting shell 301 is fixedly connected to the second slider 303. The second slider 303 slides It is dynamically installed at the bottom of the sliding sleeve 206. During use, the third slider 308 in the first sliding groove 104 will drive the rectangular rod 307, the rectangular sleeve 306, the sliding rod 304 and the micrometer 305 to move accordingly. When the second electric push rod 205 is started to extend and retract, the sliding sleeve 206 cooperates with the second slider 303 to drive the detection component 3 to move up and down. During the up and down movement of the detection component 3, the rectangular rod 307 and the rectangular sleeve 306 will offset the distance change by sliding. At the same time, during the up and down movement of the detection component 3, the first electric push rod 204 will be driven to rise and fall synchronously. During the process, the first slider 203 installed with the first electric push rod 204 will offset the distance change by sliding up and down inside the first sliding groove 104. Therefore, the distance between the three positioning columns 501 can be adjusted.

[0028] The output end of the first motor 108 is fixedly connected to the end of the first one-way screw rod 106. The outer surface of the first one-way screw rod 106 is threaded through the outer surface of the second sliding table 103. The outer surface of the first one-way screw rod 106 can move through the outer surfaces of the two first sliding tables 102. By starting the first motor 108 to drive the first one-way screw rod 106 to rotate, the second sliding table 103 can be driven away from the adjacent first sliding table 102.

[0029] The use steps of the present invention are as follows: when using the device to detect the stability performance of the produced precision gears, first, the positioning holes at the centers of the three precision gears are passed through the three positioning posts 501. During the process, the spline grooves in the positioning holes of the precision gears are aligned with the limiting protrusions 502 on the surfaces of the positioning posts 501. Since the limiting protrusions 502 on the surfaces of the positioning posts 501 at the tops of the two first sliding tables 102 are not in the same direction and correspond to the positions of the spline grooves of the precision gears after the meshing state, the two precision gears after installation will be in a meshing state after being close to each other. Subsequently, the third motor 409 is started to drive one of the second bevel gears 404 to rotate. At this time, the second bevel gear 404 will simultaneously drive one of the positioning posts 501 and the first bevel gear 403 to rotate synchronously. When the first bevel gear 403 rotates, it will drive the transmission rod 407 to rotate. The limiting block 408 and the limiting groove 406 cooperate to limit the transmission rod 407 and the transmission sleeve 405. Therefore, when the transmission rod 407 rotates, it will drive the other first bevel gear 403 and the second bevel gear 404 to rotate. At this time, the two second bevel gears 404 will drive the positioning columns 501 on the two first sliding tables 102 to rotate, and the two precision gears on the surface of the first sliding table 102 that are in a state of mutual meshing will be in an active rotation state. During the process, the precision gear in the middle position will drive the precision gear above the second sliding table 103 to rotate, and the precision gear above the second sliding table 103 is in a passive rotation state, so it can effectively simulate various working states of the precision gears. At the same time, during the rotation of the precision gears, the detection head of the micrometer 305 contacts the surface of the precision gears, and the first electric push rod 204 will drive the micrometer 305 to move back and forth in a straight line through the connecting shell 301 and the sliding rod 304 after extension. During the process, the micrometer 305 will continuously detect the displacement changes of different positions on the surface of the precision gears in the dynamic state, so as to judge the stability performance of the precision gears according to the displacement changes. The present device can effectively simulate the working state of the precision gears and detect their stability performance. The detection result is more in line with the stability performance of the precision gears in the actual working process, and the accuracy is higher. During use, by starting the first motor 108 to drive the first unidirectional screw rod 106 to rotate, the second sliding platform 103 can be driven to move away from the adjacent first sliding platform 102, and then starting the second motor 109 to drive the first bidirectional screw rod 107 to rotate can drive the two first sliding platforms 102 to move away from each other synchronously. When the two first sliding platforms 102 move away from each other, the first mounting frame 401 at the bottom will drive the corresponding first bevel gear 403 to move synchronously, and the transmission rod 407 and the transmission sleeve 405 will maintain a synchronous rotation state under the limiting action of the limiting block 408 and the limiting groove 406 and move with the two first bevel gears 403. Therefore, the distance between the three positioning columns 501 can be adjusted, and during the movement of the first sliding platform 102 and the second sliding platform 103, the first slide groove 104 in The third slider 308 will drive the rectangular rod 307, the rectangular sleeve 306, the sliding rod 304 and the micrometer 305 to move along. When the second electric push rod 205 is started to extend and retract, the sliding sleeve 206 cooperates with the second slider 303 to drive the detection component 3 to move up and down. During the up and down movement of the detection component 3, the rectangular rod 307 and the rectangular sleeve 306 will offset the distance change by sliding. At the same time, during the up and down movement of the detection component 3, the first electric push rod 204 will be driven to rise and fall synchronously. During the process, the first slider 203 installed with the first electric push rod 204 will offset the distance change by sliding up and down inside the first slide groove 104. Therefore, the distance between the three positioning columns 501 can be adjusted to meet the stability performance detection of precision gear products with different diameters, thereby improving the versatility and practicality of the device.

[0030] Embodiment 2: Figure 1-Figure 8 As shown, the difference between the basis and the embodiment is that the interior of the positioning column 501 near the upper part is arranged as a cavity and the outer surface is equidistantly provided with a plurality of openings 503, the interior of the positioning column 501 is rotatably connected to a second bidirectional screw rod 504 through a bearing, the outer surface of the second bidirectional screw rod 504 is symmetrically threadedly connected to a threaded sleeve 506, and an interference block 507 is slidably arranged between the inner surface walls of the opening 503, the opening 503 is mainly used to accommodate the interference block 507 so that it can only move horizontally, and when in use, when the second bidirectional screw rod 504 rotates, under the action of the bidirectional thread on the surface, the two threaded sleeves 506 will move synchronously and approach each other.

[0031] The first rotating seat 508 is symmetrically fixedly connected to the position of the resistance block 507 near the top and the bottom, and a plurality of second rotating seats 509 are equidistantly fixedly connected to the outer surfaces of the two threaded sleeves 506. A connecting rod 510 is rotatably connected between the inner surface walls of adjacent first rotating seats 508 and second rotating seats 509. When in use, the two threaded sleeves 506 will move synchronously and approach each other. At this time, the second rotating seat 509 on the surface will apply a thrust to the connecting rod 510, thereby causing the connection between the connecting rod 510 and the second rotating seat 509 to rotate and tilt more. At this time, the other end of the connecting rod 510 will rotate with the first rotating seat 508 and push the resistance block 507 in the opening 503 to move outward.

[0032] The outer surface of the resistance block 507 away from the first rotating seat 508 is bonded with a rubber pad, and the top of the second bidirectional screw rod 504 is fixedly connected with a rotating cap 505. The outer surface of the rotating cap 505 is provided with anti-skid grooves. The diameter of the rotating cap 505 is equal to the diameter of the positioning column 501. By adding a rubber pad on the surface of the resistance block 507, the friction between the resistance block 507 and the inner wall of the positioning hole inside the precision gear is increased. The rotating cap 505 has anti-skid grooves on the surface to facilitate the rotation of the second bidirectional screw rod 504. The diameters of the rotating cap 505 and the positioning column 501 are equal, which can ensure that the precision gear passes through the rotating cap 505 and is sleeved on the outside of the positioning column 501.

[0033] The use steps of the present invention are as follows: when in use, after the precision gear sleeve is arranged on the surface of the positioning column 501, the rotating cap 505 can be rotated to drive the second bidirectional screw rod 504 to rotate inside the positioning column 501. When the second bidirectional screw rod 504 rotates, under the action of the bidirectional thread on the surface, the two threaded sleeves 506 will move synchronously and approach each other. At this time, the second rotating seat 509 on the surface will apply a thrust to the connecting rod 510, thereby causing the connection between the connecting rod 510 and the second rotating seat 509 to rotate and become more inclined. At this time, the other end of the connecting rod 510 will rotate with the first rotating seat 508 and push the interference block 507 in the opening 503 to move outward, thereby interfering with the central positioning hole of the precision gear, thereby fixing the precision gear. When releasing the fixation, the rotating cap 505 can be rotated in the opposite direction.
