[0023] Beneficial effects of the present invention:

[0024] (1) During operation, the wheel hub is transferred to the first docking groove for assembly through the transfer equipment of other stations, and is replaced through the transfer equipment of other stations. When placed, the wheel hub is kept coaxial with the first docking groove as much as possible. The thermal expansion mechanism contains at least two sets of ABS gear rings, and each set of ABS gear rings is arranged vertically and coaxially. When one of the two sets of ABS gear rings is assembling the gear rings, the other set of ABS gear rings is loaded and heated at a constant temperature. The overall process interval is compressed by synchronous operation to increase production. When clamping, the clamping mechanism moves at a fixed point on the three-dimensional slide. First, the ABS gear ring on the top layer is clamped and removed at a fixed point. After the elastic force of each first spring is used to maintain a stable balance, the ABS gear ring and the adjustment tube are accurately coaxial. Then, the gear ring is moved to the top of the wheel hub and the clamped ABS gear ring is accurately mounted on the center of the wheel hub. When mounting, the ABS gear ring is first suspended on the wheel hub, and then the distance between the ABS gear ring and the wheel hub installation position is detected by each distance measuring probe. According to the distance reading, the three-dimensional slide table is driven to accurately adjust the position of the ABS gear ring, and the ABS gear ring is accurately positioned so that it can be accurately aligned with the wheel hub and press-fitted.

[0025] (2) When working, in coordination with the distance measurement value of the distance measuring probe, the first motor rotates the first screw rod, lifts and lowers the first slider, adjusts the inclination angle of the positioning inclined rod, thereby adjusting the movement of each positioning slider, and then adjusting the envelope circle diameter of each clamping cross bar tip, accurately cooperating with the distance measurement of the distance measuring probe, so that the adjustment cylinder of the clamping mechanism always remains accurately coaxial with the ABS gear ring and the wheel hub, and the inner surface of the ABS gear ring is positioned by the positioning inclined block, and the envelope circle at the end of the limit cross bar is adjusted to adapt to ABS gear rings of different sizes. When the limiting cross bar is retracted to the outer peripheral side wall of the ABS gear ring as the positioning slider moves, the positioning bevel first contacts the upper edge of the outer peripheral side wall of the ABS gear ring, and the limiting cross bar and the clamping cross bar are respectively located on the upper and lower sides of the ABS gear ring under the movement of the three-dimensional slide. Then the first motor is started, and the positioning bevel first rises through the inclined surface and gradually approaches the inner ring of the ABS gear ring as the limiting cross bar moves. Then, when the lower tip of the positioning bevel is flush with the inner ring of the ABS gear ring, the positioning bevel falls, and the trigger block contacts the trigger probe and sends a signal to stop. The first motor is stopped, so that the tip of the limit cross bar and the tip of the clamping cross bar are exactly flush with the inner ring of the ABS gear ring, and the ABS gear ring and the adjustment cylinder are coaxial through the reverse connection of the positioning bevel block and the ABS gear ring, which is convenient for subsequent positioning. When the ABS gear ring is to be press-fitted on the wheel hub, the center top of the wheel hub pushes the positioning bevel block upward, and all the trigger blocks are separated from the trigger probe to determine whether the press fitting is accurately positioned. If the positioning is inaccurate, there will definitely be a trigger block that always abuts against the trigger probe, so that each press fitting is automatically checked to ensure that the ABS gear ring is horizontally and smoothly pressed onto the wheel hub. Then the positioning bevel block is relatively moved to be flush with the limit cross bar. By detecting the moving distance of each trigger block relative to each corresponding trigger probe, the clamping mechanism and the ABS gear ring can be released from the restriction, which is convenient for the clamping mechanism to loosen the ABS gear ring for subsequent clamping and pressing, and the horizontality data of the ABS gear ring during each press fitting can be timely detected and obtained, so as to adjust the connection state of the three-dimensional slide and the clamping mechanism, so as to facilitate the clamping mechanism to always maintain an accurate vertical setting;

[0026] (3) During operation, the heating chamber is filled with heat transfer oil. The two heating chambers are rotated and alternately press-fit the ABS gear rings and heat them for a period of time by rotating the motor and the rotating frame. When the ABS gear rings in one of the heating chambers are continuously press-fitted, the second motor corresponding to the heating chamber works intermittently and periodically as each ABS gear ring is clamped. The second screw is driven to rotate by the first transmission shaft and the second transmission shaft, thereby pushing each second slider to rise synchronously by a fixed distance, which is the thickness of the ABS gear ring. The receiving frame in the other heating chamber is first raised to the highest point, and then a number of ABS gear rings stacked in a vertical row are placed. The receiving frame is then lowered to receive the ABS gear rings into the heating chamber, so that the overall stacking thickness of the ABS gear rings is maintained at the highest level not higher than the liquid level of the heat transfer oil in the heating chamber. Then, the ABS gear rings are heated by the heating tube and kept at a uniform and constant temperature by the heat transfer oil. At the same time, the same temperature is maintained during clamping, so that the ABS gear rings expand uniformly and stably, ensuring the stability and accuracy of the shape and structure of the ABS gear rings during press-fitting.

A positioning top block 302 is slidably connected between the clamping cross bar 206 and the limiting cross bar 301. A first spring 303 is installed between the positioning top block 302 and the clamping vertical rod 205.

[0041] When the present embodiment is working, the wheel hub 602 is transferred to the first docking groove 103 by the transfer equipment of other stations for assembly, and is replaced by the transfer equipment of other stations. When placed, the wheel hub 602 is kept coaxial with the first docking groove 103 as much as possible. The thermal expansion mechanism 106 contains at least two groups of ABS gear rings 601, and each group of ABS gear rings 601 is arranged in a vertical coaxial stack. When one of the two groups of ABS gear rings 601 is performing gear ring assembly work, the other group of ABS gear rings 601 is filled and heated at a constant temperature. The overall process interval is compressed by synchronous operation to improve production. When clamping, the clamping mechanism 105 first clamps the fixed point under the fixed point movement of the three-dimensional slide 102 Grab the ABS gear ring 601 on the top layer, and keep a stable balance through the elastic force of each first spring 303, so that the ABS gear ring 601 and the adjustment tube 201 are accurately coaxial, and then move to just above the position of the wheel hub 602, and accurately fit the clamped ABS gear ring 601 on the center of the wheel hub 602. When fitting, first hover the ABS gear ring 601 on the wheel hub 602, and then use each distance measuring probe 304 to detect the distance between itself and the surrounding of the installation position of the wheel hub 602, and drive the three-dimensional slide 102 to accurately adjust the position of the ABS gear ring 601 according to the distance reading, and accurately position the ABS gear ring 601 so that it can be accurately aligned with the wheel hub 602 and press-fitted.

[0042] A plurality of pairs of limit cross frames 202 are installed on the outer periphery of the lower end of the adjusting cylinder 201, and a positioning slide groove 203 is provided on the relative inner side walls of each pair of limit cross frames 202. The limit cross frames 202 are slidably connected with a positioning slider 204 through the positioning slide groove 203, and the positioning slider 204 is connected to the upper end of the clamping vertical rod 205. A first motor 207 is installed on the inner top of the adjusting cylinder 201, and a first screw 208 is installed at the lower end of the driving shaft of the first motor 207. A threaded sleeve on the first screw 208 A first slider 209 is connected, and a positioning oblique rod 210 is installed between the outer periphery of the first slider 209 and each positioning slider 204. The positioning oblique rod 210 is hinged to the first slider 209 and the positioning slider 204 respectively. A plurality of limiting sliding grooves 211 are provided on the side wall of the adjustment cylinder 201 to cooperate with the positioning oblique rod 210 to penetrate through the side wall. The clamping vertical rod 205 and the limiting horizontal rod 301, as well as the clamping horizontal rod 206 and the clamping vertical rod 205 are kept stably limited by the support frame 305.

[0043] When this embodiment is working, in coordination with the distance measurement value of the distance measuring probe 304, the first motor 207 rotates the first screw 208, lifts and lowers the first slider 209, and adjusts the inclination angle of the positioning inclined rod 210, thereby adjusting the movement of each positioning slider 204, and then adjusting the envelope circle diameter of the tip of each clamping cross bar 206, accurately cooperating with the distance measurement of the distance measuring probe 304, so that the adjustment cylinder 201 of the clamping mechanism 105 always remains accurately coaxial with the ABS ring gear 601 and the wheel hub 602.

[0044] The limiting cross bar 301 and the clamping cross bar 206 keep their ends flush, and the cross-sectional widths of the clamping cross bar 206 are all smaller than the tooth groove width of the ABS gear ring 601. A mounting frame 401 is installed on the top of one end of the limiting cross bar 301 close to the center of the annular array, and a limiting slider 402 is slidably connected to the middle of the mounting frame 401. A second spring 403 is installed between the limiting slider 402 and the mounting frame 401. A positioning inclined block 405 is installed on one side of the limiting slider 402 close to the center of the annular array, and a trigger block 404 is installed on the other side of the limiting slider 402. A trigger probe 406 is installed on the limiting cross bar 301 and directly below the trigger block 404.

[0045] When the present embodiment is working, the inner surface of the ABS gear ring 601 is positioned by the positioning bevel block 405, and the envelope ring at the end of the limiting cross bar 301 is adjusted to adapt to ABS gear rings 601 of different sizes. When the limiting cross bar 301 is retracted to the outer peripheral side wall of the ABS gear ring 601 as the positioning slider 204 moves, the positioning bevel block 405 first contacts the upper edge of the outer peripheral side wall of the ABS gear ring 601, and the limiting cross bar 301 and the clamping cross bar 206 are respectively located at the upper and lower sides of the ABS gear ring 601 under the movement of the three-dimensional slide 102, and then the third The first motor 207 is started, and the positioning bevel 405 first rises through the inclined surface and gradually approaches the inner ring of the ABS gear ring 601 as the limiting cross bar 301 moves. Then, when the lower tip of the positioning bevel 405 is flush with the inner ring of the ABS gear ring 601, the positioning bevel 405 falls, and the trigger block 404 abuts against the trigger probe 406 and sends a signal to stop the first motor 207, so that the tip of the limiting cross bar 301 and the tip of the clamping cross bar 206 are exactly flush with the inner ring of the ABS gear ring 601, and the positioning bevel 405 and the hook of the ABS gear ring 601 The reverse direction makes the ABS gear ring 601 coaxial with the adjustment cylinder 201, which is convenient for subsequent positioning. When the ABS gear ring 601 is to be press-fitted on the wheel hub 602, the center top of the wheel hub 602 pushes the positioning bevel 405 upward, and all the trigger blocks 404 are separated from the trigger probe 406 to determine whether the press-fitting is accurately positioned. If the positioning is inaccurate, there will definitely be a trigger block 404 that is always in contact with the trigger probe 406, so that each press-fitting is automatically checked to ensure that the ABS gear ring 601 is horizontally and stably press-fitted on the wheel hub 602. The positioning bevel block 405 moves relatively to be flush with the limiting cross bar 301. By detecting the moving distance of each trigger block 404 relative to each corresponding trigger probe 406, the clamping mechanism 105 and the ABS gear ring 601 can be released from the restriction, making it convenient for the clamping mechanism 105 to loosen the ABS gear ring 601 for subsequent clamping and pressing, and the horizontality data of the ABS gear ring 601 during each pressing can be detected and obtained in time, so as to adjust the connection state between the three-dimensional slide 102 and the clamping mechanism 105, and facilitate the clamping mechanism 105 to always maintain an accurate vertical setting.

[0046] The thermal expansion mechanism 106 includes a rotating motor 501, a rotating frame 502 is installed on the upper end of the driving shaft of the rotating motor 501, and outer support cylinders 503 are installed on both sides of the rotating frame 502. An inner support cylinder 505 is coaxially installed inside the outer support cylinder 503. The cylindrical gap between the outer support cylinder 503 and the inner support cylinder 505 is a heating chamber 514. Evenly distributed heating tubes 504 are buried in the side wall of the outer support cylinder 503. A plurality of evenly distributed second transmission boxes 513 in a ring array are installed on the inner wall of the inner support cylinder 505, and the inner support cylinder 505 is connected to the second transmission box 513.

[0047] The lower end of the second transmission box 513 is connected with the first transmission box 508, the top of the first transmission box 508 is installed with a second motor 509, the second transmission box 513 is rotatably connected with the second screw rod 506, the lower end of the driving shaft of the second motor 509 is installed with the first transmission shaft 510, the side wall of the first transmission box 508 is penetrated with a plurality of second transmission shafts 511 evenly distributed in a circular array, the second screw rod 506, the lower end of the first transmission shaft 510 and the two ends of the second transmission shaft 511 are all installed with bevel gears, and the second screw rod 506 and the second transmission shaft 511 as well as the second transmission shaft 511 and the first transmission shaft 510 are all mutually driven by the meshing of the bevel gears;

[0048] A second slider 507 is threadedly sleeved on the second screw rod 506, a receiving frame 512 is provided in the heating chamber 514, and the second slider 507 is connected to the receiving frame 512;

[0049] When the present embodiment is working, the heating chamber 514 is filled with heat transfer oil, and the two heating chambers 514 are alternately pressed and heated for a period of time by rotating the motor 501 and the rotating frame 502. When the ABS ring gear 601 of one of the heating chambers 514 is continuously pressed, the second motor 509 corresponding to the heating chamber 514 works intermittently and periodically as each ABS ring gear 601 is clamped, and drives the second screw 506 to rotate through the first transmission shaft 510 and the second transmission shaft 511, thereby pushing each second slider 507 to rise synchronously by a fixed length. That is, the thickness of the ABS gear ring 601, the receiving frame 512 in the other heating chamber 514 is first raised to the highest point, and then a number of ABS gear rings 601 stacked in a vertical row are placed, and then the ABS gear rings 601 are placed in the heating chamber 514, so that the overall stacking thickness of the ABS gear rings 601 is maintained at the highest level below the liquid level of the heat transfer oil in the heating chamber 514, and then heated by the heating tube 504 and kept at a uniform constant temperature by the heat transfer oil, and the same temperature is also maintained during clamping, so that the ABS gear ring 601 expands uniformly and stably, ensuring the stability and accuracy of the shape structure of the ABS gear ring 601 during press-fitting.

[0050] When the present invention is in use, the wheel hub 602 is transferred to the first docking groove 103 by the transfer equipment of other stations for assembly, and is replaced by the transfer equipment of other stations. When placed, the wheel hub 602 is kept coaxial with the first docking groove 103 as much as possible. The thermal expansion mechanism 106 contains at least two groups of ABS gear rings 601, and each group of ABS gear rings 601 is arranged in a vertical coaxial stack. When one of the two groups of ABS gear rings 601 is performing gear ring assembly work, the other group of ABS gear rings 601 is loaded and heated at a constant temperature. The overall process interval is compressed by synchronous operation to improve production. When clamping, the clamping mechanism 105 first clamps the fixed point under the fixed point movement of the three-dimensional slide 102 The ABS gear ring 601 located on the uppermost layer is taken down, and after the elastic force of each first spring 303 maintains a stable balance, the ABS gear ring 601 and the adjustment tube 201 are accurately coaxial, and then the ABS gear ring 601 is moved to the position just above the wheel hub 602, and the clamped ABS gear ring 601 is accurately mounted on the center of the wheel hub 602. When mounting, the ABS gear ring 601 is first suspended on the wheel hub 602, and then the distance between itself and the surrounding of the installation position of the wheel hub 602 is detected by each distance measuring probe 304, and the position of the ABS gear ring 601 is accurately adjusted by driving the three-dimensional slide 102 according to the distance reading, and the ABS gear ring 601 is accurately positioned so that it can be accurately aligned with the wheel hub 602 and press-fitted;

[0051] During operation, in coordination with the distance measurement value of the distance measuring probe 304, the first motor 207 rotates the first screw 208, lifts and lowers the first slider 209, and adjusts the inclination angle of the positioning inclined rod 210, thereby adjusting the movement of each positioning slider 204, and then adjusting the envelope circle diameter of the tip of each clamping cross bar 206, accurately cooperating with the distance measurement of the distance measuring probe 304, so that the adjustment cylinder 201 of the clamping mechanism 105 always remains accurately coaxial with the ABS gear ring 601 and the wheel hub 602, and the inner surface of the ABS gear ring 601 is positioned by the positioning inclined block 405, and the envelope circle at the end of the limit cross bar 301 is adjusted to adapt to ABS gear rings 601 of different sizes. When the cross bar 301 is retracted to the outer peripheral side wall of the ABS gear ring 601 as the positioning slider 204 moves, the positioning bevel block 405 first contacts the upper edge of the outer peripheral side wall of the ABS gear ring 601, and the limiting cross bar 301 and the clamping cross bar 206 are respectively located on the upper and lower sides of the ABS gear ring 601 under the movement of the three-dimensional slide 102. Then the first motor 207 is started, and the positioning bevel block 405 first rises through the inclined surface and gradually approaches the inner ring of the ABS gear ring 601 as the limiting cross bar 301 moves. Then, when the lower tip of the positioning bevel block 405 is flush with the inner ring of the ABS gear ring 601, the positioning bevel block 405 falls, and the trigger block 404 contacts the trigger probe 406 and triggers. The first motor 207 is stopped by a signal, so that the tip of the limit cross bar 301 and the tip of the clamping cross bar 206 are exactly flush with the inner ring of the ABS gear ring 601, and the ABS gear ring 601 is connected to the ABS gear ring 601 in the reverse direction by the positioning bevel block 405, so that the ABS gear ring 601 is coaxial with the adjustment cylinder 201, which is convenient for subsequent positioning. When the ABS gear ring 601 is to be press-fitted on the wheel hub 602, the center top of the wheel hub 602 pushes the positioning bevel block 405 upward, and all the trigger blocks 404 are separated from the trigger probe 406 to determine whether the press fitting is accurately positioned. If the positioning is inaccurate, there will definitely be a trigger block 404 that is always in contact with the trigger probe 406, so that each press fitting is accurate. An automatic inspection is performed to ensure that the ABS gear ring 601 is horizontally and smoothly pressed onto the wheel hub 602, and then the positioning bevel block 405 is relatively moved to be flush with the limiting cross bar 301. By detecting the moving distance of each trigger block 404 relative to each corresponding trigger probe 406, the clamping mechanism 105 and the ABS gear ring 601 can be released from the restriction, which makes it convenient for the clamping mechanism 105 to release the ABS gear ring 601 for subsequent clamping and pressing, and the horizontality data of the ABS gear ring 601 during each pressing can be detected and obtained in time, so as to adjust the connection state between the three-dimensional slide 102 and the clamping mechanism 105, so as to facilitate the clamping mechanism 105 to always maintain an accurate vertical setting;

[0052] During operation, the heating chamber 514 is filled with heat transfer oil, and the two heating chambers 514 are alternately pressed and heated for a period of time by rotating the motor 501 and the rotating frame 502. When the ABS ring gear 601 of one of the heating chambers 514 is continuously pressed, the second motor 509 corresponding to the heating chamber 514 works intermittently and periodically as each ABS ring gear 601 is clamped, and drives the second screw 506 to rotate through the first transmission shaft 510 and the second transmission shaft 511, thereby pushing each second slider 507 to rise synchronously by a fixed distance, which is A. To determine the thickness of the BS gear ring 601, the receiving frame 512 in the other heating chamber 514 is first raised to the highest position, and then a number of ABS gear rings 601 stacked in a vertical row are placed, and then the ABS gear rings 601 are lowered to be received into the heating chamber 514, so that the overall stacking thickness of the ABS gear rings 601 is maintained at the highest level below the liquid level of the heat transfer oil in the heating chamber 514, and then heated by the heating tube 504 and kept at a uniform constant temperature by the heat transfer oil, and the same temperature is also maintained during clamping, so that the ABS gear rings 601 expand uniformly and stably, ensuring the stability and accuracy of the shape structure of the ABS gear rings 601 during press-fitting.

[0053] The present invention is not limited to press-fitting gear rings. The ABS gear ring 601 is only a preferred embodiment of the present invention. The present invention can be preferably implemented in press-fitting wheel-shaped, ring-shaped and other circular objects. It can be matched with different production lines only through simple size adaptation, without large-scale modification or addition or reduction, and has a wide range of applications.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
