Here, the working processes of the lifting driving assembly, the deflection driving assembly and the rotation driving assembly are all realized by the control part 2 to realize cooperative work, and the specific structure, the operation principle and the improvement effect are as follows:
as shown in fig. 4, the lifting driving assembly includes a positioning column 12 vertically fixed on the frame body 1, a lifting support plate 13 vertically slidably disposed on the positioning column 12, a threaded rod 14 vertically rotatably disposed on the frame body 1 and in threaded connection with the lifting support plate 13, a lifting driving element fixedly disposed on the frame body 1 and used for driving the threaded rod 14 to rotate, and a transmission assembly 15, four matching bodies 16 are fixedly disposed on the lifting support plate 13, the four matching bodies 16 are respectively used for rotationally matching with the four lifting rotating rods 8, perforations are disposed on the matching bodies 16, a circle of second limiting ring grooves are formed on the perforated side walls (in the manufacturing process, the matching bodies 16 can be composed of two parts, one part is provided with the second limiting ring grooves, then after the two parts are fastened in a butting manner, the matching bodies 16 with the second limiting ring grooves are formed inside), a circle of first limiting ring body is disposed on the lifting rotating rod 8, the lifting rotating rod 8 passes through the perforations and is rotationally connected with the matching bodies 16, the first limiting ring body is disposed in the second limiting ring grooves to realize limiting of the lifting rotating rod 8 relative to the matching bodies 16, and the lifting support plate 13 moves in the vertical direction of the lifting support plate 16 in the height direction to drive the lifting rotating rod 16.
In this embodiment, the positioning posts 12 have two, four threaded rods 14, the bottom of each threaded rod 14 is provided with a fixed sprocket, and the four sprockets are engaged by a chain transmission, and the lifting driving element and the transmission assembly 15 are used for driving one of the sprockets to rotate.
Compared with the original scheme, the optimization scheme adopted in the method does not need 4 oil cylinders any more, but directly drives the 4 lifting rotating rods 8 to synchronously lift through the same lifting support plate 13, so that the synchronous rates of the lifting rotating rods are completely consistent, the control device does not need to simultaneously control the operation of the 4 oil cylinders, only the lifting driving element and the transmission assembly 15 are controlled, and programming is simpler.
As shown in fig. 5, the deflection driving assembly includes a deflection driving member symmetrically disposed on the lifting support 13, a deflection gear 17 fixedly disposed at the bottom end of the lifting rotating rod 8, a deflection driving element fixedly disposed below the lifting support 13, and a transmission assembly 18, the deflection driving member includes a limiting block 19 fixedly disposed on the lifting support 13 and having a transverse limiting hole, and two bidirectional tooth bodies 20 disposed in a manner of completing transverse sliding through the transverse limiting hole, racks are disposed on two lateral sides of the bidirectional tooth bodies 20, respectively, and are cooperatively connected with the deflection gear 17 disposed on the side, the two bidirectional tooth bodies 20 are cooperatively connected with a bidirectional screw rod 21 in a threaded manner, the bidirectional screw rod 21 is rotatably disposed on the lifting support 13 and cannot move transversely relative to the lifting support 13 (only limited to rotate relative to the lifting support 13), the bidirectional screw rod 21 is in a form of being in a forward thread and a reverse thread respectively, and the bidirectional screw rod 21 is in butt joint with the output shaft of the deflection driving element and the transmission assembly 18 in a form of a belt wheel.
Compared with the original scheme, the optimized scheme adopted by the method does not need 4 corner oil cylinders any more, but directly deflects the deflection gear 17 through two bidirectional tooth bodies 20 driven by the same bidirectional screw rod 21, and racks are arranged on two sides of the bidirectional tooth bodies 20, and the deflection performed by the four bidirectional tooth bodies is also in a symmetrical form.
After the lifting driving assembly and the deflection driving assembly are designed, the wheel hub can be positioned and clamped, in the operation process, the four rolling blocks 9 are lifted to the highest position shown in fig. 2 through the lifting driving assembly, then deflected to the state shown in fig. 1 through the deflection driving assembly, so that a sufficient space is reserved above the base 5 to put the wheel hub on (if the wheel hub is not deflected, the clamping phenomenon is generated as in fig. 2), the wheel hub cannot be put in, then deflected by the deflection driving assembly to return to the state shown in fig. 2, and the four rolling blocks 9 are lowered through the lifting driving assembly until the rolling wheels 11 are pressed around the inner ring of the wheel hub, so that the positioning and clamping effects are achieved.
As shown in fig. 1 and 2, the rotary driving assembly includes a driven gear 22 fixedly disposed on the spindle 10 and facing away from an end portion of the pressing roller 11, a driving shaft 23 transversely rotatably disposed on the detecting table 4 and having both ends penetrating out of the detecting table 4, two driving gears 24 fixedly disposed at both ends of the driving shaft 23, a rotary driving element fixedly disposed in the detecting table 4 and for driving the driving shaft 23 to rotate, and a transmission assembly, wherein the driving gears 24 are coplanar with the two driven gears 22 on the same side, and the driven gears 22 can mesh with the driving gears 24 below the driven gears along with the descent of the pressing roller 9.
The scheme adopts the pressing roller 11 to press the inner ring of the wheel hub, and then the pressing roller 11 drives the wheel hub to rotate through friction force after rotating, so that the rotating transposition process of the wheel hub is realized.
If a driving element is designed on each rolling block 9 to drive the main shaft 10 to rotate, the 4 driving elements not only require higher cost, but also have very precise coordination control, otherwise, the phenomenon of skidding occurs when the speed is slightly deviated, and all the applicant considers that a uniform rotary driving element and a transmission assembly are adopted to synchronously drive the 4 main shafts 10 to rotate together to be the best form.
Here, the function of the table 3 for performing small-amplitude height adjustment on the detection table 4 (generally, the fine adjustment is performed by using the threaded rod 14, which is not described more than the conventional technical scheme), and because when the pressing roller block 9 descends to the lowest position, it is required to ensure that the driven gear 22 is just meshed with the driving gear 24, and meanwhile, the inner ring of the hub is tightly attached to the pressing roller 11, in this high environment, it is required to adjust the height position of the detection table 4 relative to the table 3 to ensure that the pressing roller 11 is tightly attached to the hub, and then the first adjustment is performed, so that the detection can be performed on the hub with the same specification.
As shown in fig. 1 to 3, a weight 25 is provided at an eccentric position on the driven gear 22, and the driven gear 22 is free from constraint: the weight 25 will deflect the driven gear 22 under the force of gravity until the weight 25 is at the lowest position of the driven gear 22 to complete the automatic positioning calibration of the driven gear 22.
As shown in fig. 3, 6 and 7, the circumference of the driving gear 24 is uniformly distributed with a plurality of attracting magnets 26 (objects with the past performance of being attracted by magnetic substances), an electromagnet 27 is further arranged at a position, close to the driving gear 24, on the workbench 3, a circuit assembly is fixedly arranged on the frame body 1, the electromagnet 27 is arranged in the circuit assembly, a circuit breaking interface 28 is arranged on the circuit assembly, a guide rod 29 with electric conduction capacity is arranged on a transverse fixing frame on the lifting support plate 13, two ends of the circuit breaking interface 28 are positioned at a path where the guide rod 29 lifts along with the lifting support plate 13, the driving gear 24, the workbench 3 and the positioning table 7 around the driving gear 24 are made of nonmagnetic materials, the circuit assembly forms a passage through the moment of passing through the circuit breaking interface 28 after the height of the guide rod 29 changes, and at the moment, the electromagnet 27 generates magnetism to attract the attracting magnet 26 closest to the position closest to the circuit assembly, and automatic positioning and calibration of the driving gear 24 are completed.
Because the driven gear 22 and the driving gear 24 need to be meshed, separated, re-meshed and re-separated for a plurality of times in the scheme, in order to ensure that the driven gear 22 and the driving gear cannot collide with teeth in the process of meshing, the design ensures that the driven gear 22 and the driving gear can complete the position calibration function after being separated, and the driven gear and the driving gear are always at a preset reasonable angle before being secondarily meshed.
Because the driven gear 22 is fixed to the main shaft 10 with little weight, the applicant sets the weight block 25 at the eccentric position of the driven gear 22, and when the driven gear 22 is not restrained, the weight block 25 has weight, so it automatically adjusts the position of the driven gear 22 until the weight block 25 is positioned at the lowest position of the driven gear 22, so that the driven gear 22 has only one state at the last time, and the angle of the driven gear 22 in this state is swung toward the designed state in advance, and then is positioned at this calibrated position each time when the driven gear 22 is stabilized.
Because the driving gear 24 is fixed on the driving shaft 23, the driving shaft 23 spans the whole detecting platform 4, the factors are large, the weight of the driving shaft is heavy, and if the same weighting block 25 form as that of the driven gear 22 is adopted, the weighting block 25 can cause the driven gear 22 to be excessively heavy during starting, so that the rotary driving element and the transmission assembly need to provide higher power, and the applicant replaces a calibration form after comprehensive consideration, and the method of the electromagnet 27 is adopted to realize the method.
Every time the lifting support plate 13 is lifted, the guide rod 29 fixedly arranged on the lifting support plate 13 can form a passage for a circuit assembly at an instant when passing through the circuit breaking interface 28, then the electromagnet 27 is electrified to generate magnetism, the electromagnet 26 closest to the driving gear 24 is attracted to the driving gear, the attraction magnet 26 is transversely aligned with the electromagnet 27, and the driving gear 24 is a part with central symmetry, so that the attraction magnet 26 is uniformly distributed circumferentially, and then the swinging angle is designed in advance, so that the accurate positioning and calibration effects can be achieved. Then, when the guide bar 29 passes through the breaking interface 28, the circuit assembly is broken, and the electromagnet 27 is demagnetized, so that the electromagnet 27 does not have a blocking effect on the operation of the drive shaft 23.
