Description

Technical Field

[0001] The invention relates to the technical field related to wheel hub bearing processing, in particular to a clamping structure for processing automobile wheel hub bearings. Background Art

[0002] The main function of the hub bearing is to bear the load and provide precise guidance for the rotation of the hub. It bears both axial load and radial load and is a very important component. Traditional automobile wheel bearings are composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line.

[0003] Automobile wheel hub bearings need to be clamped and fixed during processing. Since automobile wheel hub bearings have different shapes and structures, some wheel hub bearings are already connected with a mounting plate during production, or the automobile wheel hub bearings and the mounting plate are manufactured as one piece. As a result, the conventional clamping structure for clamping cylindrical wheel hub bearings is not suitable for clamping work for processing different types of wheel hub bearings. Therefore, the versatility and practicality are low. To this end, we propose a clamping structure for processing automobile wheel hub bearings to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a clamping structure for processing automobile wheel hub bearings to solve the problems raised in the above-mentioned background technology.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. Example

[0021] See also Figure 1 , 2 A clamping structure for processing automobile wheel hub bearings, comprising a workbench 1, the workbench 1 is provided with a rectangular groove 2, the rectangular groove 2 is provided with a first movable frame 3, a second movable frame 13 and a moving mechanism, wherein the second movable frame 13 is fixedly connected and arranged in the rectangular groove 2, the first movable frame 3 and the second movable frame 13 are both provided with a movable groove 7, the movable groove 7 is provided with a bidirectional threaded rod 8, the bidirectional threaded rod 8 is symmetrically provided with two second sliders 12, the second sliders 12 are both connected with vertical plates 14, and the ends of the vertical plates 14 close to each other can be connected with a V-shaped clamping member 15, and the moving mechanism is used to drive the first movable frame 3 to move in the rectangular groove 2.

[0022] Specifically, the driving mechanism includes a threaded rod 4, a driving motor 5 and a first slider 9, the output shaft of the driving motor 5 is connected to one end of the threaded rod 4, the threaded rod 4 is sleeved with the first slider 9, and one end of the first slider 9 is connected to the first movable frame 3.

[0023] Preferably, limit rods 6 are provided on both sides of the threaded rod 4, and limit plates 10 are sleeved on the limit rods 6. One end of the limit plate 10 is connected to the first movable frame 3. The limit rods 6 and the limit plate 10 are symmetrically arranged on both sides of the threaded rod 4 and the first slider 9, respectively. Through this arrangement, the stability of the movement of the first movable frame 3 in the rectangular groove 2 can be ensured, thereby improving the working stability of the overall equipment.

[0024] Preferably, the edges of the rectangular groove 2 and the movable groove 7 are respectively provided with Figure 2 The first scale line 16 and the second scale line 17 shown are used to measure the length and diameter of the processed hub bearing respectively, and at the same time, the distance between the first movable frame 3 and the second movable frame 13 can be measured for subsequent processing.

[0025] Working principle: When in use, the distance between the first movable frame 3 and the second movable frame 13 is adjusted according to the shape of the wheel hub bearing to be processed. When the wheel hub bearing is provided with a mounting plate, the driving motor 5 is started to drive the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the first slider 9 to move and then drives the first movable frame 3 to move in the rectangular groove 2, driving the first movable frame 3 and the second movable frame 13 to approach each other. The rotating handle 11 is manually twisted to make the rotating handle 11 drive the bidirectional threaded rod 8 to rotate. When the bidirectional threaded rod 8 rotates, it can drive the two second sliders 12 to move away from or close to each other. After controlling the two sliders to the appropriate position, the wheel hub bearing to be processed is placed between the V-shaped clamping pieces 15, and then the two second sliders 12 are controlled to approach each other to drive the V-shaped clamping pieces 15 to move close to each other, so as to realize the clamping treatment of the wheel hub bearing to be processed. When clamping the wheel hub bearing without a mounting plate, it is not necessary to drive the first movable frame 3 and the second movable frame 13 to approach each other. The wheel hub bearing can be clamped only by the V-shaped clamping piece on the first movable frame 3. Example

[0026] See also Figure 3 , 4 On the basis of Example 1, in order to improve the stability and applicability of clamping wheel hub bearings of different shapes, a movable shaft 18 is provided at the end of the vertical plate 14, and two clamping plates 19 are connected to the movable shaft 18. The relative angle between the two clamping plates 19 is adjustable, and a fastening handle 21 is provided on the movable shaft 18. In this embodiment, a clamping groove 20 is provided on the clamping plate 19, and an elastic anti-skid pad 22 is provided in the clamping groove 20. One side of the elastic anti-skid pad 22 is in contact with the outer wall of the mounting plate to improve the clamping effect of the mounting plate.

[0027] Working principle: Since the clamping plate clamps the wheel hub bearing with the mounting plate, when in use, the relative angle between the two clamping plates 19 is adjusted according to the diameter size of the bearing mounting plate, so that the clamping plate can fit well with the outer wall of the mounting plate, and then the position of the clamping plate 19 is fixed by tightening the handle 21 to prevent it from rotating accidentally.

[0028] 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.
