Description

Technical Field

[0001] This utility model relates to the field of brake disc screw fastening technology, specifically a brake disc screw fastening mechanism. Background Technology

[0002] As a core component of the vehicle braking system, the precision and stability of the screw fastening of the brake disc directly affect the braking effect and driving safety. Automated fastening is a key process in automobile manufacturing production lines.

[0003] Existing brake disc screw fastening mechanisms are mostly dedicated structures with fixed bit spacing, only compatible with a single model of brake disc. For different specifications of products, the actuator needs to be changed, which is time-consuming and has poor adaptability, making it difficult to meet the needs of multi-variety mixed production lines. At the same time, the transmission end of traditional mechanisms is mostly a rigid connection, which cannot compensate for the angular deviation of brake disc clamping or station positioning, and is prone to problems such as misalignment between bit and screw, resulting in stripped threads, misaligned screws, and reduced fastening pass rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a brake disc screw fastening mechanism, which solves the problems of cumbersome replacement of different specifications of products and misalignment of the screwdriver bit and screw when fixing the brake disc on the wheel hub, resulting in stripped threads and misaligned screws.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 A brake disc screw fastening mechanism in this embodiment includes an upper sliding push plate 10. A screw fixing motor assembly 6 is fixedly installed above the upper sliding push plate 10. A universal joint 14 is fixedly installed at the drive end of the screw fixing motor assembly 6 below the upper sliding push plate 10. A telescopic rod 15 is fixedly installed at one end of the universal joint 14 away from the upper sliding push plate 10, and the other end of the telescopic rod 15 is also fixedly connected to the universal joint 14. A connecting rod 16 is fixedly connected at one end of the universal joint 14 away from the telescopic rod 15. A screwdriver bit 19 is fixedly installed at the other end of the connecting rod 16. A sliding sleeve 20 is provided on the outside of the screwdriver bit 19, and the connecting rod 16 is slidably installed inside the sliding sleeve 20. The sliding sleeve 20 is slidably installed on the adjusting fixing cover 13. The adjusting fixing cover 13 is fixedly installed on the adjusting fixing plate 12. A spacing adjusting disc 17 is rotatably installed above the adjusting fixing plate 12 and below the adjusting fixing cover 13, and the sliding sleeve 20 is sleeved on the spacing adjusting disc 17. The end of the spacing adjustment plate 17 away from the adjustment fixing plate 12 is threaded with a bird beak 18. The adjustment fixing plate 12 is fixedly installed on the lower sliding push plate 11, and the lower sliding push plate 11 is slidably installed on several evenly distributed sliding guide rods 3.

[0018] The screwdriver bit 19 and the beak 18 are adjusted synchronously by adjusting the pitch adjustment disc 17 installed inside the adjustment and fixing cover 13 to adapt to the layout of brake disc screws with different pitches. After adjustment, the screw fixing motor 6 is started, and the first electric cylinder 4 is started to push the upper sliding push plate 10 downward, so that the force is transmitted to the connecting rod 16, which ultimately drives the screwdriver bit 19 to rotate, realizing screw fastening. The connecting rod 16 can slide in the sliding sleeve 20 to adapt to the axial displacement of fastening. The telescopic rod 15 cooperates with the double universal joint 14 to compensate for the angle deviation. The transmission design of the double universal joint 14 and the telescopic rod 15 can effectively compensate for the angle deviation of brake disc installation and work position positioning, ensuring that the screwdriver bit 19 and the screw are always coaxially attached, avoiding problems such as stripping and twisting, and improving the fastening qualification rate.

[0019] A second electric cylinder 7 is fixedly connected to one end of the lower sliding push plate 11. The second electric cylinder 7 is fixedly installed on the lower fixed plate 8, and the lower fixed plate 8 is slidably installed on the sliding guide rod 3. A second servo motor 9 is fixedly connected to the bottom end of the lower fixed plate 8 through a transmission screw. The upper sliding push plate 10 is slidably installed on the sliding guide rod 3, and the upper sliding push plate 10 is located away from the second electric cylinder 7. The drive end of the first electric cylinder 4 is fixedly connected to the upper sliding push plate 10. The first electric cylinder 4 is fixedly installed on the upper fixed plate 5. The upper fixed plate 5 is slidably installed on the sliding guide rod 3 located away from the upper sliding push plate 10. A first servo motor 1 is fixedly connected to the upper fixed plate 5 through a transmission screw. The first servo motor 1 is fixedly installed on the upper fixed frame 2, and the upper fixed frame 2 fixes the end of the sliding guide rod 3 located away from the upper fixed plate 5.

[0020] In this mechanism, depending on the model of the wheel hub, the first servo motor 1 is activated to drive the upper fixed plate 5 to slide along the sliding guide rod 3 via the transmission screw. Simultaneously, the second servo motor 9 is activated to drive the lower fixed plate 8 to move up and down along the sliding guide rod 3 via the transmission screw. This drives the lower sliding push plate 11 and the adjusting fixed plate 12 to adjust the spacing, allowing the screw fixing motor group 6 to move quickly to the brake disc screw working area. This achieves overall coarse positioning of the locking mechanism, making it suitable for fixing brake discs of different wheel hub models. The first electric cylinder 4 is activated to drive the upper sliding push plate 10 to feed towards the working end along the sliding guide rod 3, bringing the screw fixing motor group 6 and the transmission and locking components closer to the screw. The second electric cylinder 7 simultaneously drives the lower sliding push plate 11 to feed in the same direction along the sliding guide rod 3, driving the spacing adjustment and guiding components to follow. This, in conjunction with the upper components, achieves precise proximity of the locking end, ensuring the alignment accuracy between the bit and the screw.

[0021] The working principle of the above embodiment is as follows: Rotating the spacing adjustment disc 17 on the adjusting fixing plate 12 drives the sliding sleeve 20 to move, and cooperating with the beak 18 with threaded connection, the working spacing of the screwdriver bit 19 is precisely adjusted to adapt to the layout of brake disc screws of different specifications. The first servo motor 1 is started to drive the upper fixing plate 5 to slide along the sliding guide rod 3 through the transmission screw, which drives the entire locking execution end to move to the locking position of the brake disc screw to achieve coarse positioning. The first electric cylinder 4 drives the upper sliding push plate 10 to move downward along the sliding guide rod 3, and the second electric cylinder 7 drives the lower sliding push plate 11 to feed synchronously, so that the screwdriver bit 19 is close to the screw. The telescopic rod 15 and the universal joints 14 at both ends are adapted to the screw installation angle deviation to ensure that the bit and the screw are coaxially attached. The screw fixing motor 6 is started, and the power is transmitted to the screwdriver bit 19 through the universal joint 14, telescopic rod 15 and connecting rod 16, which drives the bit to rotate to complete the screw locking. The connecting rod 16 slides in the sliding sleeve 20 to adapt to the axial displacement during the locking process.
