Description

Technical Field

[0001] This utility model relates to a brake disc positioning device, belonging to the field of brake disc processing technology. Background Technology

[0002] In the field of automotive brake disc machining, existing technologies typically employ mechanical fixtures or hydraulic systems for centering and positioning. However, these traditional methods have many shortcomings and are insufficient to meet the requirements of high-precision machining.

[0003] Mechanical clamps suffer from insufficient repeatability due to large gaps in the transmission chain, making it difficult to meet accuracy requirements of IT7 and above. Hydraulic systems are affected by oil temperature fluctuations, resulting in poor positioning stability. Furthermore, traditional structures are incompatible with centering of brake discs with a wide range of diameters, limiting their applicability.

[0004] On the other hand, hard contact between the fixture and the brake disc surface leads to wear on both the brake disc and the fixture surface. The fixture requires repair after a certain number of uses, resulting in poor reliability and high maintenance costs. Furthermore, the hard contact also affects the quality of the finished brake disc. Additionally, traditional methods involve many manual interventions, have low automation levels, and are difficult to integrate into intelligent production lines. Therefore, researching a novel brake disc positioning device is of great practical significance. Utility Model Content

[0029] Example:

[0030] like Figure 1-4 As shown, this utility model provides a brake disc positioning device, including: a support assembly, which includes a support frame 1 and a mounting plate 2 disposed on the top of the support frame 1. The support frame 1 is welded from steel pipes, and the mounting plate 2 is detachably connected and fixed to the support frame 1 by bolts. A protective cover 3 is provided on the outer side of the support frame 1; a transmission assembly, which includes a drive unit located below the mounting plate 2 and a turntable 4 connected to the drive unit. The turntable 4 is rotatably mounted above the mounting plate 2, and at least two arc-shaped guide grooves 41 are evenly opened on the turntable 4. The drive unit... Used to drive the turntable 4 to rotate; a follower assembly, the follower assembly being disposed above the mounting plate 2 and the number of follower assemblies being the same as the number of arc-shaped guide grooves 41, the follower assembly including a guide rail 5 fixed to the upper surface of the mounting plate 2 and located outside the turntable 4, the guide rail 5 being detachably mounted to the upper surface of the mounting plate 2 by bolts, a guide plate 6 being slidably fitted on the guide rail 5, the guide plate 6 having a linkage part at one end near the turntable 4 that engages with the arc-shaped guide groove 41, the turntable 4 driving the guide plate 6 to move along the guide rail 5 through the linkage part. It should be noted that, to ensure the accuracy of brake disc positioning, such as Figure 1 As shown, four arc-shaped guide grooves 41 are evenly provided on the turntable 4, and four sets of follow-up components are provided above the mounting plate 2.

[0031] By coordinating the turntable 4 with the linkage unit, the rotational motion of the drive unit is converted into the synchronous linear motion of multiple guide plates 6, which solves the problems of difficult positioning and large positioning error in the production process of brake discs. It not only effectively improves the positioning efficiency and positioning accuracy, but also improves the applicability of the positioning device described in this application, making it compatible with the positioning operation of various types of brake discs. Moreover, the positioning process does not require manual intervention, which is conducive to integration into intelligent production lines.

[0032] Specifically, such as Figure 2-4As shown, the linkage includes a guide post 7 disposed at one end of the guide plate 6 near the turntable 4, and a guide bearing 8 sleeved on the guide post 7. The guide post 7 is screwed to the guide plate 6, extends into the arc-shaped guide groove 41 and extends through the turntable 4, and the guide bearing 8 rolls in contact with the inner wall of the arc-shaped guide groove 41. The guide bearing 8 is used to ensure that the guide post 7 slides smoothly in the arc-shaped guide groove 41, avoiding problems such as large positioning errors and short service life caused by motion jamming. In some embodiments, the guide post 7 can be set to protrude a certain distance from the upper surface of the guide plate 6 so that it can play the role of supporting the inner hole of the brake disc. In this application, because a receiving part is provided, the guide post 7 does not protrude from the upper surface of the guide plate 6. It can be understood that during the rotation of the turntable 4, the guide post 7 moves along the trajectory of the arc-shaped guide groove 41, thereby driving the guide plate 6 to move forward or backward along the guide rail 5.

[0033] Specifically, such as Figure 3 As shown, two sets of guide bearings 8 are spaced apart along the axial direction on the guide post 7, and a spacer 9 is provided between the two sets of guide bearings 8. By setting two sets of guide bearings 8, the stability of the guide post 7 is effectively improved. Furthermore, by providing a spacer 9 between the two sets of guide bearings 8, the mutual influence between the guide bearings 8 during operation can be avoided, the guide bearings 8 can be protected from damage, and the radial runout of the guide post 7 can be reduced.

[0034] Specifically, such as Figure 1 , 2 As shown in Figure 4, a receiving part that contacts the brake disc is also provided above the guide plate 6. The receiving part moves synchronously with the guide plate 6 and includes a vertical plate 10 fixed above the guide plate 6. A limiting post 11 is provided at the front end of the vertical plate 10. The limiting post 11 is used to contact the inner wall of the brake disc to position the brake disc. It should be noted that the vertical plate 10 is screwed above the guide plate 6. This arrangement increases the distance between the brake disc surface and the turntable 4 during brake disc positioning operations, preventing the brake disc picking and placing robot arm from colliding with the turntable 4 and causing damage during the brake disc picking and placing process.

[0035] Specifically, such as Figure 1 , 2 As shown in Figure 4, the limiting post 11 is disposed through the front end of the upright plate 10. A fixing hole is provided on the front side of the upright plate 10, and a threaded ball-head plunger 12 is provided in the fixing hole. The end of the ball-head plunger 12 abuts against the limiting post 11 to fix its position. This arrangement facilitates adjustment of the telescopic length of the limiting post 11 relative to the upper surface of the upright plate 10 to accommodate brake discs with different axial heights, further improving applicability.

[0036] Specifically, the upright plate 10 is also provided with several sets of rolling bearings 13. The rolling bearings 13 are arranged in an array behind the limiting post 11, and the rolling bearings 13 at least partially protrude from the upper surface of the upright plate 10 to support the brake disc surface. It should be noted that "behind" refers to the position on the upright plate 10 away from the turntable 4 relative to the limiting post 11. With this arrangement, when the brake disc is placed on the upright plate 10, the brake disc surface contacts the rolling bearings 13. Then, when the follow-up component moves to support the inner hole of the brake disc, the receiving part and the brake disc make rolling contact, avoiding the problem of sliding friction between the brake disc and the upright plate 10 that causes wear on the brake disc surface, thus ensuring the production quality of the brake disc.

[0037] Specifically, to ensure the stability of the brake disc after positioning and to avoid wear of the brake disc caused by hard contact between the limiting post 11 and the inner hole of the brake disc, the limiting post 11 is fitted with an anti-slip rubber sleeve on its outer periphery.

[0038] Specifically, such as Figure 2 As shown, the drive unit includes a spindle 14, a bushing 15, and a drive motor 16. One end of the bushing 15 is fixedly connected to the lower surface of the mounting plate 2, and the other end is fitted with the drive motor 16. One end of the spindle 14 is connected to the output shaft of the drive motor 16, and the other end of the spindle 14 passes through the bushing 15 and the mounting plate 2 in sequence before connecting to the turntable 4. A bearing is provided inside the bushing 15 and is sleeved on the spindle 14. It should be noted that the bushing 15 contains a thrust ball bearing and a deep groove ball bearing. The thrust ball bearing is used to bear the axial load during operation, and the deep groove ball bearing is used to radially support the spindle 14. This arrangement provides stable support for the spindle 14, ensuring the stability and reliability of the spindle 14 during operation, reducing the wear of the spindle 14, and effectively extending the service life of the spindle 14.

[0039] Specifically, such as Figure 5 As shown, to further enhance the connection stability between the spindle 14 and the turntable 4 and avoid the turntable 4 from swaying during operation, an abutment step 141 is provided around the spindle 14. The abutment step 141 and the spindle 14 are integral structures formed by machining. The end of the spindle 14 is inserted into the axis of the turntable 4. The upper surface of the abutment step 141 abuts against the lower surface of the turntable 4. The turntable 4 is connected and fixed to the spindle 14 through at least three mounting holes evenly opened in the abutment step 141. The turntable 4 and the spindle 14 are connected and fixed by bolts passing through the mounting holes.

[0040] Implementation process: During operation, the brake disc is placed flat on the positioning device described in this application. At this time, the surface of the brake disc is in contact with the rolling bearing 13. Then, the drive motor 16 is started. The drive motor 16 drives the turntable 4 to rotate through the main shaft 14. At this time, the linkage part moves along the arc-shaped guide groove 41, thereby pushing the guide plate 6 to move linearly along the guide rail 5, thereby driving the limit post 11 to support the inner hole of the brake disc, thus completing the positioning of the brake disc.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are exhaustively listed. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these modifications and improvements are all within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims.
