Abstract
Description
Technical Field
[0001] The utility model relates to the field of industrial manufacturing, and more particularly to an assembly device for a floating piston caliper. Background Art
[0002] In the automotive industry and related fields, floating piston calipers are important components in the braking system, and their assembly quality is directly related to the braking performance and driving safety of the entire vehicle. The floating piston caliper is mainly composed of two core components: the caliper body and the bracket. The caliper body is provided with a through hole, and the bracket is provided with a connecting hole. During the assembly process, the connecting hole needs to be oiled first, and then the guide pin is installed into the connecting hole of the bracket. Finally, the guide pin bolt passes through the through hole of the caliper body to complete the cooperation with the guide pin to realize the assembly between the caliper body and the bracket.
[0003] During the assembly process, oiling the connection holes, installing the guide pins, and tightening the guide pin bolts are key steps to ensure a secure connection between the caliper body and the bracket and improve overall performance. In traditional assembly processes, these processes are mostly completed manually. However, this method is not only inefficient and difficult to adapt to large-scale production needs, but also prone to problems such as uneven oiling and inaccurate control of the tightening torque of the guide pin bolts due to human factors such as fatigue and skill differences, which directly affect the assembly accuracy of the caliper and the reliability of subsequent use.
[0004] At the same time, in the conventional production process, the two key processes of oiling and guide pin bolt assembly often need to be completed at different workstations with the help of their own specific tools. Therefore, when the bracket that has completed the oiling process is transferred between workstations, there will be a series of potential risks; during the transfer of the bracket, vibration, tilt or improper operation may damage the applied oil layer and affect product quality.

Beneficial effects
[0017] In the utility model, by setting up the connecting hole oiling assembly and the guide pin locking assembly, automatic oiling and guide pin bolt tightening are achieved, thereby ensuring that the oiling is as uniform as possible, and the tightening torque of the guide pin bolt is also accurately controlled; the assembly accuracy and overall performance of the floating piston caliper are improved, and product quality problems caused by human factors are reduced; automated production can ensure that each product is assembled according to the same standards and processes, thereby improving the consistency between products.
[0018] In the present invention, the clamp body and the bracket are transported by the feeding track and the conveying tooling, which reduces the steps of manual handling and transfer, thereby significantly improving the assembly efficiency; at the same time, the bracket that has been oiled is stably transported through the cooperation of the feeding track and the conveying tooling, which can minimize the tilting, large-scale vibration and other situations during the transfer of the bracket, thereby reducing the damage to the oil layer during the transfer process, and improving the production quality of the product.

[0022] In the present invention, the oiling pin is connected to the connecting space on the rotating oiling shaft through the connecting block. This design ensures the precise docking between the oiling pin and the rotating oiling shaft. At the same time, since the diameter of the connecting block is larger than the inner diameter of the entrance of the connecting hole, only the oiling pin enters the connecting hole during oiling, thereby minimizing the risk of the oiling flange and the rotating oiling shaft being contaminated by grease and affecting the rotation of the rotating oiling shaft.

[0025] In the present invention, the cooperation between the adjustment drive device and the adjustment mounting plate enables the oil injection module to move flexibly in the horizontal direction, and can be fine-tuned in multiple directions according to actual needs, so as to adapt to the oiling requirements of connection holes of different specifications and different positions; so that the entire assembly equipment can still maintain high production efficiency and stability when facing different types of floating piston calipers.
[0026] In the present invention, the second movable frame is movably arranged on the second mounting seat through the cooperation of the slide rail and the slider, so that the tightening gun can be flexibly moved in the horizontal direction and the tightening torque of the guide pin bolt can be accurately controlled to improve product quality and product consistency.
[0027] In the present invention, the guide pin limiting module realizes the limitation of the guide pin through the coordinated action of the movable plate, the guide pin limiting block and the limiting drive cylinder; it prevents the guide pin from rotating when the tightening gun applies a tightening rotational force to the guide pin bolt, resulting in the guide pin bolt being unable to be screwed into the guide pin, thereby improving the assembly accuracy and reliability; the size of the entrance and exit opening is designed to be larger than the inner diameter of the limiting space and the diameter of the guide pin assembly part. This design enables the assembly part of the guide pin to smoothly enter the limiting space.
[0028] In the utility model, the compression spring sleeved on the connecting shaft plays a role of buffering and shock absorption when the assembly part of the guide pin enters the limit space. The compression spring can absorb part of the impact force and vibration, and avoid hard contact between the assembly part and the guide pin limit block to cause damage as much as possible.
