DETAILED DESCRIPTION

[0040] 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.

[0041] See also Figure 1-3 In an embodiment of the present invention, a bearing outer ring automatic detection device includes a support module 100, two drive modules 200, a plurality of limit modules 300, and a plurality of detection modules 400;

[0042] The support module 100 is used for support and positioning. Two driving modules 200 are arranged inside the support module 100. The support module 100 can support and limit the driving module 200. Several limiting modules 300 are arranged between the two driving modules 200. The limiting module 300 includes a positioning rod 310. Both ends of the positioning rod 310 are fixedly connected to a connecting shaft 330. The connecting shaft 330 is rotatably connected to a fixing seat 320 at the side.

[0043] A number of detection modules 400 are arranged between two driving modules 200. The driving module 200 can drive the limit module 300 and the detection module 400 to move, so that the number of limit modules 300 and the detection module 400 can move cyclically between the two driving modules 200. The detection module 400 is located between two adjacent limit modules 300. The detection module 400 includes a detection rod 410. Both ends of the detection rod 410 are rotatably connected with connecting blocks 411. The two connecting blocks 411 are fixedly connected with positioning rods 420 at the bottom of the back faces. The positioning rods 420 are slidably connected to the limit seats 430 on the sides. The detection rod 410 can rotate relative to the connecting blocks 411, and the positioning rod 420 can slide up and down inside the limit seats 430.

[0044] Specifically, the outer ring of the bearing can be rolled to the bottom of the locking rod 310. As the limit module 300 moves, the top of the outer ring of the bearing can be abutted and limited by two adjacent locking rods 310, and the detection rod 410 can be abutted against the top of the bearing ring. In this way, the locking rod 310 can push the outer ring of the bearing to move and make the outer ring of the bearing roll on the support module 100. At this time, the outer ring of the bearing can be detected by the detection rod 410 to detect whether there is deformation in various parts of the outer ring of the bearing. The outer ring of the bearing can be continuously detected. It is relatively simple to fix and loosen the outer ring of the bearing, which is conducive to the rapid detection of the outer ring of the bearing. The outer ring of the bearing can be initially and automatically detected by the device.

[0045] A rubber pad may be provided on the side of the fixing seat 320 , and the rubber pad may be pressed against the outer ring of the bearing to limit the position of the outer ring of the bearing.

[0046] Embodiment 1

[0047] like Figure 1-3 As shown, in this embodiment, the support module 100 includes a base plate 110, two limit frames 120, and four hydraulic rods 130;

[0048] The bottom plate 110 is arranged at the bottom of the driving module 200 , a groove 111 is provided on the top surface of the bottom plate 110 , two limit frames 120 are fixedly connected to the top surface of the bottom plate 110 , four hydraulic rods 130 are arranged on the top surface of the bottom plate 110 , and the hydraulic rods 130 are located at the bottom of the driving module 200 .

[0049] During specific implementation, the driving module 200 can move up and down along the inside of the limit frame 120, and the driving module 200 can be limited by the limit frame 120. The hydraulic rod 130 can support the driving module 200, and the driving module 200 can be driven to move up and down by the hydraulic rod 130. In this way, the height of the limit module 300 and the detection module 400 can be adjusted according to the size of the detected bearing outer ring, so as to adapt to the detection of bearing outer rings of different sizes.

[0050] like Figure 6-8 As shown, in this embodiment, the driving module 200 includes a fixing box 210, a power motor 220, and a limiting plate 230;

[0051] The fixed box 210 is slidably connected to the inner side of the adjacent limit frame 120, the bottom surface of the fixed box 210 is transmission-connected to the output ends of the two adjacent hydraulic rods 130, the inner side of the fixed box 210 is rotationally connected to two transmission shafts 211, the side of the transmission shaft 211 is fixedly sleeved with a transmission wheel 213, the side of the two transmission wheels 213 is transmission-connected with a transmission belt 212, the side of the plurality of fixed seats 320 is fixedly connected to the side of the transmission belt 212, and the side of the plurality of limit seats 430 is fixedly connected to the side of the transmission belt 212, The power motor 220 passes through the adjacent limiting frame 120 and is fixedly connected to the side of the fixing box 210. The output end of the power motor 220 is connected to the end of a transmission shaft 211. The limiting plate 230 is arranged inside the limiting plate 230. The connecting shaft 330 and the positioning rod 420 both pass between the inner side of the fixing box 210 and the side of the limiting plate 230. The side of the limiting plate 230 is fixedly connected with a fixing rod 231 fixedly connected to the inner side of the fixing box 210. The fixing rod 231 can support the limiting plate 230.

[0052] A plurality of detection frames 250 are fixedly connected to the inner bottom surface of the fixed box 210, a sliding frame 251 is slidably connected to the side of the detection frame 250, a U-shaped frame 253 slidably connected to the side of the sliding frame 251 is fixedly connected to the side of the detection frame 250, the inner side surface of the U-shaped frame 253 is slidably connected to the inner side surface of the adjacent positioning rod 420, a baffle 252 is fixedly connected to the inner side surface of the sliding frame 251, and the side of the baffle 252 is slidably connected to the side of the detection frame 250.

[0053] During specific implementation, the fixed box 210 can slide up and down inside the limit frame 120. The hydraulic rod 130 can drive the fixed box 210 to move up and down, so as to adjust the height of the drive module 200 as needed. The power motor 220 can drive a transmission shaft 211 to rotate. The transmission shaft 211 can drive the transmission wheel 213 on it to rotate. The transmission wheel 213 can drive the transmission belt 212 to rotate. The transmission belt 212 can drive the fixed seat 320 and the limit seat 430 to move. The fixed seat 320 can drive the clamping rod 310 to move through the connecting shaft 330. The limit seat 430 can drive the connecting block 411 to move through the positioning rod 420. The connecting block 411 can drive the detection rod 410 to move, so that the clamping rod 310 and the detection rod 410 move cyclically along the outer edge of the limit plate 230, and the outer ring of the bearing rolls on the bottom plate 110;

[0054] The detection frame 250 is in the shape of a Chinese character 'Ri'. The middle crossbar of the detection frame 250 can support the baffle 252, so as to limit the sliding frame 251 and the U-shaped frame 253. After the detection rod 410 moves to the bottom of the limit plate 230, the positioning rod 420 can smoothly pass through the end opening of the U-shaped frame 253 and enter the inside of the U-shaped frame 253. A distance sensor for detecting the moving distance of the baffle 252 can be arranged on the top surface of the detection frame 250. In this way, when the outer ring of the bearing rotates and moves following the clamping rod 310, the detection rod 410 can abut against the outer ring of the bearing. When the outer ring of the bearing is deformed, the outer ring of the bearing can push up the detection rod 410, or under the action of gravity, the detection rod 410 moves downward. When the detection rod 410 moves, the detection rod 410 can drive the positioning rod 420 to slide up and down inside the limit seat 430. The positioning rod 420 can drive the U-shaped frame 253 and the baffle 252 to move up and down. In this way, the displacement of the baffle 252 and the U-shaped frame 253 can be detected by the distance sensor, and then the deformation condition of the outer ring of the bearing can be detected, and the diameter of the outer ring of the bearing can be detected as needed.

[0055] Support rods can be arranged on the bottom of the inner side surface of the fixed box 210 corresponding to the fixed seat 320. In this way, when the clamping rod 310 moves to the bottom of the fixed box 210, the fixed seat 320 will contact the top surface of the support rod. The support rod can support and limit the clamping rod 310 through the fixed seat 320. A guide plate can be fixedly arranged on the inner side surface of the fixed box 210 corresponding to the U-shaped frame 253. After the detection rod 410 moves to the bottom of the inner side of the fixed box 210, the guide plate can support the positioning rod 420, which is convenient for the positioning rod 420 to smoothly insert into the U-shaped frame 253, and the guide plate and the support rod are staggered from each other.

[0056] Embodiment 2

[0057] On the basis of Embodiment 1, as Figure 6As shown, in this embodiment, an L-shaped plate 240 is fixedly connected to the inner side surface of the fixed box 210, and a plurality of connecting gears 500 are arranged inside the fixed box 210. The plurality of connecting gears 500 are fixedly sleeved on the connecting shaft 330 at intervals, and a gear rod meshing with the top of the adjacent connecting gear 500 is fixedly connected to the bottom surface of the L-shaped plate 240. The L-shaped plate 240 can support the gear rod, and the connecting gear 500 can move from the side of the L-shaped plate 240 to the bottom of the gear rod.

[0058] During specific implementation, when the transmission belt 212 drives the connecting shaft 330 to move through the fixed seat 320, the connecting shaft 330 can drive the connecting gear 500 thereon to move. After the connecting gear 500 engages with the gear rod, the connecting gear 500 will roll on the gear rod, so that the connecting gear 500 can drive the positioning rod 310 to rotate through the connecting shaft 330, and the positioning rod 310 can drive the outer ring of the bearing to rotate, thereby allowing the outer ring of the bearing to rotate smoothly, and a more comprehensive detection of the outer ring of the bearing can be performed.

[0059] like Figure 9-10 As shown, in this embodiment, the detection module 400 further includes two sliding seats 440, two abutment rods 460, and two insertion rods 470;

[0060] The two sliding seats 440 are respectively slidably connected to the two ends of the side of the detection rod 410, and the two abutting rods 460 are respectively slidably connected to the inner side surfaces of the bottom of the two sliding seats 440. The abutting rods 460 can slide up and down along the inner side surfaces of the bottom of the sliding seat 440. The opposite surfaces of the two abutting rods 460 are fixedly connected with positioning plates 462. The two plug-in rods 470 are respectively rotatably connected to the top of the sides of the two positioning plates 462. The two connecting blocks 411 are fixedly connected to two limit frames 450 on the sides. The sliding seat 440 is fixedly connected with two limit blocks 441 that are slidably connected to the sides of the adjacent limit frames 450. The limit seat 430 can limit the rotation of the positioning rod 420, thereby limiting the rotation of the connecting block 411. The limit block 441 can slide along the limit frame 450, so that the connecting block 411 can limit the angle of the sliding seat 440 through the limit frame 450 and the limit block 441.

[0061] In specific implementation, after the inspection of the bearing outer ring is completed, when the bearing moves to the top of the groove 111, the connecting rod 470 can be inserted into the inner ring of the bearing outer ring. At this time, the bearing can be supported by the connecting rod 470. When a depression appears inside the bearing outer ring, the detection rod 410 will move downward relative to the abutment rod 460 under the action of gravity, and the detection rod 410 will fall on the top of the bearing outer ring. When a bulge appears inside the bearing outer ring, the connecting rod 470 will lift the detection rod 410 through the bearing outer ring. In this way, the position change of the detection rod 410 can be detected by the distance sensor, so as to understand whether there is deformation inside the bearing outer ring.

[0062] A large end is provided on the top of the abutting rod 460 , and the large end of the abutting rod 460 can slide inside the sliding seat 440 . The sliding seat 440 can prevent the abutting rod 460 from detaching from the sliding seat 440 through the large end of the abutting rod 460 .

[0063] like Figure 4 , 5 As shown in FIG10 , in this embodiment, a round block 461 is fixedly connected to the bottom surface of the abutting rod 460, a fixing frame 140 fixedly connected to the bottom surface of the fixing box 210 is slidably connected to the inner surface of the bottom plate 110, a connecting plate 150 is arranged on the top of the fixing frame 140, a guide groove 151 is opened on the top surface of the connecting plate 150 corresponding to the round block 461, connecting grooves 152 are opened at both ends of the inner surface of the guide groove 151, and a guide groove 2 153 is opened on the inner surface of the connecting groove 152 away from the guide groove 151;

[0064] The inner side surface of the fixed frame 140 is rotatably connected to a connecting screw rod 142, and the top surface of the fixed frame 140 is slidably connected to a limit rod 144 that is screwed together with the connecting screw rod 142. Two sliding grooves 141 are provided on the top surface of the fixed frame 140. The inner side surface of the sliding groove 141 is slidably connected to a sliding block 143. The sliding block 143 can translate in the sliding groove 141. The inner side surface of the sliding block 143 is screwed together with a positioning screw rod 145 that is rotatably connected to the inner side surface of the connecting plate 150. The positioning screw rod 145 is screwed together with the inner side surface of the limit rod 144. The limit rod 144 can slide on the surface of the fixed frame 140. The connecting screw rod 142 can limit the position of the limit rod 144. The limit rod 144 can limit the horizontal position of the connecting plate 150 through the positioning screw rod 145. The sliding block 143 can support the connecting plate 150 through the positioning screw rod 145.

[0065] In specific implementation, when the detection module 400 moves to the bottom of the limit plate 230, the round block 461 will correspond to the end of a second guide groove 153, and then the round block 461 will move from the end of the second guide groove 153 to the inside of the second guide groove 153. At this time, the round block 461 can be supported by the connecting plate 150, thereby limiting the position of the abutment rod 460 and the plug-in rod 470. A second guide groove 153 can limit the position of the plug-in rod 470 through the round block 461. At this time, the outer ring of the bearing outer ring can be detected by the detection rod 410. After the outer ring detection is completed, the round block 461 will move into a connecting groove 152. Since the connecting groove 152 is inclined relative to the second guide groove 153, under the action of a connecting groove 152, the round block 461 can move away from the fixed box 210, and the round block 461 can drive the abutment rod 460 to move, and the abutment rod 460 can The plug-in rod 470 is driven to move by the positioning plate 462, and the abutment rod 460 can drive the sliding seat 440 to move along the detection rod 410, so that the plug-in rod 470 is inserted into the bearing. Since the bottom of the outer ring of the bearing is separated from the top surface of the bottom plate 110, the connecting plate 150 can support the bearing through the abutment rod 460 and the plug-in rod 470, and then the round block 461 will move to the inside of the guide groove 151 to detect the inside of the outer ring of the bearing. When deformation occurs inside the outer ring of the bearing, the deformation inside the bearing can be detected by the detection rod 410, and then the round block 461 will move to the inside of another connecting groove 152, and then move out of the top of the connecting plate 150 from another guide groove 2 153. Under the action of the other connecting groove 152, the round block 461 is moved to the original position, so that the plug-in rod 470 is separated from the outer ring of the bearing, so that the outer ring of the bearing can be moved out of the device.

[0066] Before detection, the connecting screw 142 can be rotated, and the connecting screw 142 can make the limit rod 144 translate along the surface of the fixed frame 140, and the limit rod 144 can drive the connecting plate 150 to move through the positioning screw 145, so that the horizontal position of the connecting plate 150 can be adjusted as needed, and then the abutment rod 460 can be gradually moved to the position corresponding to the end of the guide groove 153, so that the plug-in rod 470 can adapt to the outer ring of the bearing of different widths, and the positioning screw 145 can be rotated, and the positioning screw 145 can move upward relative to the sliding block 143 and the limit rod 144, and the positioning screw 145 can lift the connecting plate 150 upward, and then adjust the height of the connecting plate 150, so as to adapt to the detection of bearing rings of different thicknesses.

[0067] A gasket can be rotatably arranged inside the sliding seat 440 so that the gasket can rotate relative to the detection rod 410 , thereby enabling the sliding seat 440 to rotate and move relative to the detection rod 410 through the gasket.

[0068] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
