[0017] Another technical solution proposed by the present invention is to provide a detection method for a bearing inner and outer diameter detection device that can be wiped with oil, comprising the following steps:

[0018] S1: First, place the bearing body inside the discharge barrel, and mesh the first tooth groove through the reduction motor and the gear, so that the push plate passes through the discharge chute to push the bearing body inside the discharge barrel to the left. When the bearing body passes between the first cleaning cotton block and the second cleaning cotton block, the oil on the surface can be wiped off. When the tooth plate follows the push plate to move close to the position of the gear, the gear meshes with the tooth plate when it rotates, so that the tooth plate and the push plate move upward. Since the push plate is slidably connected in the discharge chute and the discharge barrel is installed on the movable plate, when the push plate moves upward, the movable plate will be lifted upward, and the bearing body will be transported to the bottom of the support rod for inspection;

[0019] S2: After the bearing body is transported to the bottom of the support rod, the clamping rod is located at the inner diameter of the bearing body. When the telescopic cylinder contracts, it drives the shell to move to the left. When the shell moves to the left, under the guidance of the guide slider and the guide groove, the movable block moves downward to squeeze the second spring, causing the squeezing block to move downward. When the squeezing block moves downward, the four groups of inclined plates drive the clamping rod to move outward on the cross guide frame. The clamping rod finally stops expanding outward due to the obstruction of the bearing body. At this time, the center of the cross guide frame is located at the center of the inner diameter of the bearing body. By observing the scale of the measuring ruler on the outside of the shell, the distance between the clamping rod and the center of the cross guide frame can be calculated, and then the inner diameter of the bearing body can be measured;

[0020] S3: When the shell moves to the left, the bearing body below it will also move to the left. When the bearing body moves to the left on the top of the workbench, its outer wall squeezes the clamping plate, so that the first rotating part drives the rotating rod to rotate around the rotating axis. The second rotating part at the other end of the rotating rod will move relatively, and its movement range is three times the movement range between the first rotating parts. Finally, the distance is measured by the ultrasonic ranging sensor in conjunction with the reflective sheet, and the outer diameter value of the bearing body is obtained through calculation.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention provides a bearing inner and outer diameter detection device and method that can wipe oil stains. First, the bearing body is evenly placed inside the discharge barrel, and the reduction motor is started. When the reduction motor rotates, it drives the gear to mesh with the first tooth groove and rotate, so that the push plate passes through the discharge chute to push the bearing body inside the discharge barrel to the left. When the bearing body passes between the first cleaning cotton block and the second cleaning cotton block, the oil stains on the surface can be wiped off. As the gear rotates, the bearing body is pushed to the bottom of the feed chute. At this time, the tooth plate follows the push plate to move close to the position of the gear. When the gear rotates next, it meshes with the tooth plate to make the tooth plate and the push plate move upward. Since the push plate is slidably connected in the discharge chute and the discharge barrel is installed on the movable plate, the movable plate will be lifted upward when the push plate moves upward, and finally the bearing body is transported to the bottom of the support rod to wait for detection, thereby realizing automatic loading and improving work efficiency.

[0023] 2. The present invention provides a bearing inner and outer diameter detection device and method that can be wiped with oil. When the push plate moves upward, the entire equipment of the movable plate will be lifted up, and the bearing body will be finally transported to the bottom of the support rod. At this time, the clamping rod is located at the inner diameter of the bearing body, and the telescopic cylinder is started. When the telescopic cylinder contracts, it drives the shell to move to the left. When the shell moves to the left, under the guidance of the guide slider and the guide groove, the movable block moves downward to squeeze the second spring, prompting the squeezing block to move downward. When the squeezing block moves downward, the four groups of inclined plates drive the clamping rod to move outward on the cross guide frame. The clamping rod finally stops expanding outward due to the obstruction of the inner wall of the bearing body. At this time, the center of the cross guide frame is located at the center of the inner diameter of the bearing body. Since the fixed block is slidably connected to the cross guide frame, the distance between the clamping rod and the center of the cross guide frame can be calculated by observing the scale of the measuring ruler on the outside of the shell, and then the inner diameter of the bearing body can be calculated, which is convenient for measurement.

[0024] 3. The present invention provides a bearing inner and outer diameter detection device and method that can be wiped with oil. When measuring the inner diameter, the shell moves to the left. When the shell moves to the left, the bearing body below it will also move to the left. When the bearing body moves to the left on the top of the workbench, its outer wall squeezes the clamping plate, so that the first sliding block slides in the first sliding groove, and the first rotating member drives the rotating rod to rotate around the rotating shaft. Since the rotating shaft is located at the four-equal points between the first rotating member and the second rotating member on the rotating rod, the second rotating member at the other end of the rotating rod will move relatively, and its movement range is three times the movement range between the first rotating members. Finally, the ultrasonic ranging sensor cooperates with the reflective sheet to measure the distance. The numerical value obtained through calculation has higher accuracy, and the outer diameter is measured together during the inner diameter measurement, and the operation process is simple.

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.

[0039] In order to solve the technical problem that the existing testing instruments need to manually load materials when testing bearings, which affects the work efficiency, such as Figure 1-Figure 5 As shown, the following preferred technical solutions are provided:

[0040] A bearing inner and outer diameter detection device capable of being wiped with oil stains, comprising a feeding mechanism 1 and an inner diameter detection mechanism 2 and an outer diameter measuring mechanism 3 arranged on the feeding mechanism 1, the feeding mechanism 1 comprising a supporting assembly 11, a cleaning assembly 12, a lifting assembly 13 and a discharging barrel 14, the supporting assembly 11 comprising a workbench 111, a feeding trough 1111 being arranged on the workbench 111, a supporting platform 112 being fixedly connected to the bottom of the workbench 111, the supporting assembly 11 also comprising a movable plate 113 movably arranged on the supporting platform 112, a discharging barrel 14 being fixedly connected to the movable plate 113, and the discharging barrel 14 is passed through from top to bottom, a bearing body 15 is contained in the discharging barrel 14, a discharging trough 141 is arranged below the discharging barrel 14, a first sliding rod 114 is fixedly connected to the bottom of the movable plate 113, and the first sliding rod 114 is slidably connected to the supporting platform 112, and the first sliding rod 114 plays a role of guiding sliding;

[0041] The cleaning assembly 12 includes a push plate 121 slidably connected to the surface of the movable plate 113, and the push plate 121 corresponds to the lower material trough 141. A semicircular groove corresponding to the bearing body 15 is provided on one side of the push plate 121. The cleaning assembly 12 also includes a first cleaning cotton block 122 embedded in the movable plate 113. The top of the movable plate 113 is fixedly connected to a bracket 123 near the edge of the first cleaning cotton block 122. The top inner wall of the bracket 123 is fixedly connected to a second slide rod 124. The second slide rod 124 The second cleaning cotton block 126 is connected to the upper slide, and the second cleaning cotton block 126 is chamfered at the lower side close to the lower barrel 14. The second sliding rod 124 is provided with a first spring 125, and the two ends of the first spring 125 are respectively connected to the second cleaning cotton block 126 and the inner wall of the top of the bracket 123. When the push plate 121 passes through the lower barrel 141, it pushes the bearing body 15 inside the lower barrel 14 out, and the oil on the surface is wiped off when passing between the first cleaning cotton block 122 and the second cleaning cotton block 126;

[0042] The lifting assembly 13 includes a first tooth groove 131 arranged at the bottom of the push plate 121, and also includes a tooth plate 132 fixedly connected to one side of the bottom of the push plate 121. The top of the support platform 112 is fixedly connected to a reduction motor 133, and the output end of the reduction motor 133 is fixedly connected to a gear 134 corresponding to the first tooth groove 131 and the teeth on the inner side of the tooth plate 132.

[0043] Specifically, the bearing body 15 is evenly placed inside the discharge barrel 14, and the reduction motor 133 is started. When the reduction motor 133 rotates, the gear 134 is driven to engage with the first tooth groove 131 to rotate, so that the push plate 121 passes through the discharge groove 141 to push the bearing body 15 inside the discharge barrel 14 to the left. When the bearing body 15 passes between the first cleaning cotton block 122 and the second cleaning cotton block 126, the oil on the surface can be wiped off, and the bearing body 15 is pushed forward as the gear 134 rotates. To the bottom of the feed trough 1111, the tooth plate 132 follows the push plate 121 to move close to the position of the gear 134, and the gear 134 engages the tooth plate 132 when it rotates, so that the tooth plate 132 and the push plate 121 move upward. Since the push plate 121 is slidably connected in the discharge trough 141, and the discharge barrel 14 is installed on the movable plate 113, when the push plate 121 moves upward, the movable plate 113 will be lifted upward, and finally the bearing body 15 will be transported to the bottom of the support rod 221 to wait for detection.

[0044] In order to solve the technical problem that the existing equipment needs to be fixed and then the inner diameter is measured using a vernier caliper, and the vernier caliper is not convenient for accurately finding the diameter, resulting in inconvenient measurement, such as Figure 6-Figure 9 As shown, the following preferred technical solutions are provided:

[0045] The inner diameter detection mechanism 2 includes a sliding component 21, a guide component 22 and a clamping component 23. The sliding component 21 includes a guide rod 212 fixedly connected to the top of the workbench 111. The guide rod 212 plays a role of linear guide. The guide rod 212 is provided with two groups. A guide sleeve 213 is slidably connected to the guide rod 212. A shell 211 is fixedly connected between the two groups of guide sleeves 213. The sliding component 21 also includes a telescopic cylinder 214 fixedly connected to the top of the workbench 111. The output end of the telescopic cylinder 214 is fixedly connected to the outside of the shell 211. When the telescopic cylinder 214 is extended or retracted, it will drive the shell 211 to move linearly.

[0046] The guide assembly 22 includes support rods 221 fixedly connected to the front and rear of the top of the workbench 111 , a guide plate 222 is fixedly connected between the two groups of support rods 221 , and the guide plate 222 has a certain inclination, and a guide groove 223 is provided at the bottom of the guide plate 222 .

[0047] The guide assembly 22 also includes a guide slider 224 slidably connected to the inside of the guide groove 223, the bottom of the guide slider 224 is fixedly connected to a movable block 225, the bottom of the movable block 225 is fixedly connected to a movable column 226, the bottom of the movable column 226 is fixedly connected to a limiting plate 227, and a second spring 228 is mounted on the movable column 226.

[0048] The clamping assembly 23 includes a cross guide frame 231 fixedly connected to the inner wall of the shell 211, and a fixed block 232 is slidably connected to the cross guide frame 231. The fixed blocks 232 are radially distributed in four groups, and a measuring ruler 2321 is fixedly connected to one group of the fixed blocks 232, and the measuring ruler 2321 penetrates and extends to the outside of the shell 211.

[0049] The clamping assembly 23 also includes a clamping rod 233 fixedly connected to the upper and lower parts of the fixed block 232. The upper end of the fixed block 232 is fixedly connected to a slanted plate 234 through the clamping rod 233. The inner sides of the slanted plates 234 are fixedly connected to movable bars 235. The clamping assembly 23 also includes an extrusion block 236 movably arranged above the interior of the shell 211. The extrusion block 236 is in the shape of a quadrangular pyramid. The outer wall of the extrusion block 236 is provided with a sliding groove 237, and the movable bar 235 is slidably connected to the interior of the sliding groove 237. The inclination of the slanted plate 234 is the same as the inclination of the side wall of the extrusion block 236. A limiting groove 238 corresponding to the limiting plate 227 is provided above the interior of the extrusion block 236, and the depth of the limiting groove 238 is greater than the thickness of the limiting plate 227. The two ends of the second spring 228 are respectively fixedly connected to the bottom of the movable block 225 and the top of the extrusion block 236.

[0050] Specifically, when the push plate 121 moves upward, the entire device of the movable plate 113 is lifted upward, and finally the bearing body 15 is transported to the bottom of the support rod 221. At this time, the clamping rod 233 is located at the inner diameter of the bearing body 15, and the telescopic cylinder 214 is started. When the telescopic cylinder 214 contracts, it drives the shell 211 to move to the left. When the shell 211 moves to the left, under the guidance of the guide slider 224 and the guide groove 223, the movable block 225 moves downward to squeeze the second spring 228, so that the squeezing block 236 moves downward. When the four groups of inclined plates 234 drive the clamping rod 233 to move outward on the cross guide frame 231, the clamping rod 233 finally stops expanding outward due to the obstruction of the inner wall of the bearing body 15. At this time, the center of the cross guide frame 231 is located at the center of the inner diameter of the bearing body 15. Since the fixing block 232 is slidably connected to the cross guide frame 231, the distance between the clamping rod 233 and the center of the cross guide frame 231 can be calculated by observing the scale of the measuring ruler 2321 outside the shell 211, and then the inner diameter of the bearing body 15 can be measured.

[0051] In order to solve the technical problem that the outer diameter needs to be tested separately from the inner diameter, the operation is relatively cumbersome, such as Figure 10-12 As shown, the following preferred technical solutions are provided:

[0052] The outer diameter measuring mechanism 3 includes a lever assembly 31, a first measuring assembly 32 and a second measuring assembly 33. The lever assembly 31 includes an L-shaped frame 311 fixedly connected to the front and rear of the top of the workbench 111. A rotating shaft 312 is rotatably connected between the other end of the L-shaped frame 311 and the workbench 111, and a rotating rod 313 is fixedly connected to the rotating shaft 312. The two ends of the rotating rod 313 are respectively provided with a first movable groove 314 and a second movable groove 315.

[0053] The first measuring component 32 includes a first slide groove 321 arranged at the front and back of the top of the workbench 111, and a first slider 323 is slidably connected in the first slide groove 321. A clamping plate 324 is fixedly connected to the top of the first slider 323, and a first rotating member 322 is fixedly connected to the outer side of the clamping plate 324, and the first rotating member 322 is movably connected to the inside of the first movable groove 314. The first measuring component 32 also includes a fixing plate 325 fixedly connected to the front and back of the top of the workbench 111, and a third spring 326 is fixedly connected between the fixing plate 325 and the clamping plate 324. The third spring 326 is used to press the clamping plate 324 against the outer wall of the bearing body 15.

[0054] The second measuring component 33 includes a second slide groove 331 arranged at the front and rear of the top of the workbench 111, and the second slide groove 331 is slidably connected to the inside of the second slide groove 331, and the top of the second slide block 333 is fixedly connected to a fixed plate 334, and the outer side of the fixed plate 334 is fixedly connected to a second rotating member 332, and the second rotating member 332 is movably connected to the inside of the second movable groove 315, and the rotating shaft 312 is located at the quarter-dividing point between the first rotating member 322 and the second rotating member 332 on the rotating rod 313, and the inner sides of the two groups of fixed plates 334 are respectively provided with ultrasonic ranging sensors 335 and reflective sheets 336.

[0055] Specifically, when measuring the inner diameter, the shell 211 moves to the left, and when the shell 211 moves to the left, the bearing body 15 below it will also move to the left. When the bearing body 15 moves to the left on the top of the workbench 111, its outer wall squeezes the clamping plate 324, so that the first slider 323 slides in the first slide groove 321, and the first rotating member 322 drives the rotating rod 313 to rotate around the rotating shaft 312. Since the rotating shaft 312 is located at the four-equal-division point between the first rotating member 322 and the second rotating member 332 on the rotating rod 313, the second rotating member 332 at the other end of the rotating rod 313 will move relatively, and its movement range is three times the movement range between the first rotating members 322. Finally, the ultrasonic ranging sensor 335 cooperates with the reflector 336 to measure the distance, and the value is obtained through calculation.

[0056] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, a detection method of a bearing inner and outer diameter detection device that can be wiped with oil, comprising the following steps:

[0057] Step 1: First, place the bearing body 15 inside the discharge barrel 14, and mesh the first tooth groove 131 through the reduction motor 133 and the gear 134, so that the push plate 121 passes through the discharge trough 141 to push the bearing body 15 inside the discharge barrel 14 to the left. The bearing body 15 can wipe the oil on the surface when passing between the first cleaning cotton block 122 and the second cleaning cotton block 126. When the tooth plate 132 follows the push plate 121 to move close to the position of the gear 134, the gear 134 meshes with the tooth plate 132 when it rotates, so that the tooth plate 132 and the push plate 121 move upward. Since the push plate 121 is slidably connected in the discharge trough 141, the discharge barrel 14 is installed on the movable plate 113, so when the push plate 121 moves upward, the movable plate 113 will be lifted upward, and the bearing body 15 will be transported to the bottom of the support rod 221 to wait for detection;

[0058] Step 2: After the bearing body 15 is transported to the bottom of the support rod 221, the clamping rod 233 is located at the inner diameter of the bearing body 15. When the telescopic cylinder 214 contracts, it drives the housing 211 to move to the left. When the housing 211 moves to the left, under the guidance of the guide slider 224 and the guide groove 223, the movable block 225 moves downward to squeeze the second spring 228, prompting the squeezing block 236 to move downward. When the squeezing block 236 moves downward, the four groups of inclined plates 234 drive the clamping rod 233 to move outward on the cross guide frame 231. The clamping rod 233 finally stops expanding outward due to the obstruction of the bearing body 15. At this time, the center of the cross guide frame 231 is located at the center of the inner diameter of the bearing body 15. By observing the scale of the measuring ruler 2321 on the outside of the housing 211, the distance between the clamping rod 233 and the center of the cross guide frame 231 can be calculated, and then the inner diameter of the bearing body 15 can be measured.

[0059] Step three: When the shell 211 moves to the left, the bearing body 15 below it will also move to the left. When the bearing body 15 moves to the left on the top of the workbench 111, its outer wall squeezes the clamping plate 324, so that the first rotating member 322 drives the rotating rod 313 to rotate around the rotating shaft 312. The second rotating member 332 at the other end of the rotating rod 313 will move relatively, and its movement range is three times the movement range between the first rotating members 322. Finally, the ultrasonic ranging sensor 335 cooperates with the reflector 336 to measure the distance, and the outer diameter value of the bearing body 15 is obtained through calculation.

8. A detection method for the bearing inner and outer diameter detection device capable of being wiped with oil as claimed in any one of claims 1 to 7, characterized in that: The following steps are involved: S1: First, the bearing body (15) is placed inside the discharge barrel (14), and the first tooth groove (131) is engaged by the reduction motor (133) and the gear (134), so that the push plate (121) passes through the discharge groove (141) to push the bearing body (15) inside the discharge barrel (14) to the left. When the bearing body (15) passes between the first cleaning cotton block (122) and the second cleaning cotton block (126), the oil on the surface can be wiped off. When the tooth plate (132) follows the push plate (1 21) moves close to the position of the gear (134), and the gear (134) engages the tooth plate (132) when it rotates, so that the tooth plate (132) and the push plate (121) move upward. Since the push plate (121) is slidably connected in the discharge chute (141), and the discharge barrel (14) is installed on the movable plate (113), when the push plate (121) moves upward, the movable plate (113) is lifted upward, and the bearing body (15) is transported to the bottom of the support rod (221) to wait for detection; S2: After the bearing body (15) is transported to the bottom of the support rod (221), the clamping rod (233) is located at the inner diameter of the bearing body (15). When the telescopic cylinder (214) contracts, it drives the housing (211) to move to the left. When the housing (211) moves to the left, under the guidance of the guide slider (224) and the guide groove (223), the movable block (225) moves downward to squeeze the second spring (228), so that the squeezing block (236) moves downward. When the squeezing block (236) moves downward, the four groups The inclined plate (234) drives the clamping rod (233) to move outward on the cross guide frame (231), and the clamping rod (233) finally stops expanding outward due to the obstruction of the bearing body (15). At this time, the center of the cross guide frame (231) is located at the center of the inner diameter of the bearing body (15). By observing the scale of the measuring ruler (2321) outside the housing (211), the distance between the clamping rod (233) and the center of the cross guide frame (231) can be calculated, and then the inner diameter of the bearing body (15) can be measured; S3: When the housing (211) moves to the left, the bearing body (15) below it will also move to the left. When the bearing body (15) moves to the left on the top of the workbench (111), its outer wall squeezes the clamping plate (324), so that the first rotating member (322) drives the rotating rod (313) to rotate around the rotating shaft (312). The second rotating member (332) at the other end of the rotating rod (313) will move relatively, and its movement range is three times the movement range between the first rotating members (322). Finally, the ultrasonic distance sensor (335) cooperates with the reflective sheet (336) to measure the distance, and the outer diameter value of the bearing body (15) is obtained through calculation.
