Description

Technical Field

[0001] The utility model particularly relates to an upper pressing device for assembling a small brake assembly. Background Art

[0002] In the field of parking brakes, the brake subassembly plays a vital role. When the driver activates the brake through the handbrake after the vehicle stops, the brake subassembly begins to work. It pushes the piston to make the brake pad and brake disc tightly fit to ensure the vehicle is parked stably. The core components of the brake subassembly include spring seat sleeve, spring, steel ball sleeve, steel ball sleeve screw, threaded guide rod, steel ball and gasket. The precise coordination between the various components is the key to ensure the braking effect.

[0003] The Chinese utility model patent publication number "CN205025976U" discloses a brake caliper assembly design, and the brake subassembly mentioned in this application is a part of the brake caliper assembly, which is responsible for installation on the parking caliper body. One end is connected to the rotating bracket through a steel ball sleeve screw, and the other end is connected to the adjusting screw sleeve through a threaded guide rod. During operation, the movement of the rotating bracket will drive the steel ball sleeve screw, and after a series of precision transmissions, it will drive the brake pads on the brake caliper to achieve the braking function. Through the specification attached to the patent disclosure document Figure 1 , you can clearly see the specific structure of the brake subassembly and its installation position.

[0004] However, in the production process of brake subassemblies, after the processing of each component is completed, it needs to go through the assembly process to form a complete assembly. This involves key steps such as the press-fitting of the threaded guide rod, the assembly of the steel ball sleeve screw, and the press-fit riveting action. Existing press-fitting tools have limitations in this regard. It is usually difficult to complete all processes on a single device, resulting in the need to use multiple devices and transfer products multiple times, making it impossible to achieve one-machine molding, which increases the complexity and cost of production.

[0005] China's invention patent publication number "CN103272954B" discloses a clamping device for an exhaust brake valve, which mainly includes a set of cylinders and a set of pressure rod mechanisms. Although this device has advantages in some aspects, it still faces the problem of low efficiency when directly applied to the assembly of brake subassemblies. A single operation can only complete the press-fitting of threaded guide rods or the assembly of steel ball sleeve screws, and it is impossible to achieve multi-process press-fitting on one device. Therefore, it is still necessary to equip multiple devices and multiple product operations, and it is not possible to achieve one-machine molding, and the process is cumbersome.

[0006] To sum up, in response to the shortcomings of the prior art, this application proposes a press-fitting device for a small brake assembly, aiming to solve the problem of press-fitting of multiple processes on one machine, improve production efficiency, reduce production costs, and at the same time ensure product quality and performance. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a press-fitting device for assembling a brake subassembly in view of the deficiencies of the above-mentioned prior art, which can realize press-fitting in multiple processes without setting up multiple devices or running the product multiple times, thereby facilitating the assembly of the brake subassembly and improving production efficiency.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an upper pressing device for assembling a brake subassembly, comprising a first mounting plate, a first cylinder distributed above the first mounting plate, and a pressure head assembly distributed below the first mounting plate, wherein the first mounting plate is provided with a first through hole corresponding to the first cylinder, and is characterized in that: the pressure head assembly comprises a sliding plate, a first slide rail slidably connected to the sliding plate and fixed below the first mounting plate, the sliding plate is linked with a plurality of groups of pressure rod mechanisms, the plurality of groups of pressure rod mechanisms are arranged in sequence and at intervals along a direction parallel to the axis of the first slide rail, the end of the sliding plate is linked with a second cylinder, the second cylinder can drive the sliding plate to reciprocate along the axis of the first slide rail, and the first cylinder can drive a group of pressure rod mechanisms to reciprocate along the axis direction of the first cylinder through the first through hole.

[0009] Compared with conventional press-fitting devices, the upper press-fitting device proposed in this technical solution can realize press-fitting in multiple processes, without the need to set up multiple devices or to run the product multiple times, which facilitates the assembly of the brake subassembly and improves production efficiency. The specific operation is as follows: the second cylinder drives the sliding plate to move along the first slide rail, changing the positions of several groups of pressure rod mechanisms, so that according to the actual needs, the first cylinder controls different pressure rod mechanisms through the first through hole, truly realizing one machine for multiple uses.
