Description

Technical Field

[0001] The utility model specifically relates to an assembly machine for a small brake assembly. Background Art

[0002] In the field of parking brakes, the small brake assembly plays a crucial role. When the driver activates the brake by pulling the handbrake after the vehicle has come to a stop, the small brake assembly begins to function. It pushes the piston, causing the brake pads to tightly engage with the brake disc, ensuring the vehicle is parked stably. The core components of the small brake assembly include a spring seat sleeve, a spring, a steel ball sleeve, a steel ball sleeve screw, a threaded guide rod, steel balls, and gaskets. The precise fit between the various components is the key to ensuring the braking effect.

[0003] The Chinese utility model patent publication number "CN205025976U" discloses a design of a brake caliper assembly. The small brake assembly mentioned in this application is a part of the brake caliper assembly and is responsible for being installed 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 sleeve through a threaded guide rod. During operation, the movement of the rotating bracket drives the steel ball sleeve screw, and through a series of precise transmissions, the brake pads on the brake caliper are driven to achieve the braking function. Through the attached Figure 1 drawings in the patent publication document, the specific structure and installation position of the small brake assembly can be clearly seen.

[0004] However, during the production process of the small brake assembly, after each component is processed, it needs to go through an 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 downward pressing and riveting edge actions. Existing assembly machines have limitations in this regard. Usually, it is difficult to complete all processes on a single device, resulting in the necessity to use multiple devices and transfer the products multiple times. It is impossible to achieve one-machine forming, increasing the complexity and cost of production.

[0005] Secondly, when the threaded guide rod is first press-fitted, due to the action of the spring, the threaded guide rod has a tendency to move upward. At this time, simply relying on the existing press-fitting device, there is no limiting component for the threaded guide rod provided below. After the cylinder retracts, the threaded guide rod pops up upward, and at this time, it is impossible to clamp the steel ball sleeve screw. Therefore, the existing press-fitting device cannot be directly applied to the assembly of the small brake assembly.

[0006] In summary, aiming at the deficiencies of the existing technology, this application proposes an assembly machine for a small brake assembly, aiming to solve the problem of multi-process press-fitting on one machine, which can be directly applied to the assembly of the small brake assembly, improve production efficiency, reduce production costs, and at the same time ensure the product quality and performance. Content of the Utility Model

[0007] The technical problem to be solved by the present utility model is to provide an assembly machine for a small brake assembly in view of the deficiencies of the above-mentioned prior art, which can realize multi-process assembly of the small brake assembly, without setting up multiple devices, nor repeatedly moving the product, facilitating the assembly of the small brake assembly, improving production efficiency, and during the entire assembly process, the steel ball sleeve screw will not sway left and right or move up and down, and the threaded guide rod will not move up and down either.

[0008] To achieve the above object, the present utility model provides the following technical solution: An assembly machine for a small brake assembly, including a workbench and a fixture installed on the workbench and used for clamping the product, characterized in that: it further includes a pressing head device distributed above the fixture, a clamping device distributed below the fixture, and a plurality of groups of riveting mechanisms distributed at intervals around the fixture; the pressing head device includes a first mounting plate, a first cylinder distributed above the first mounting plate, and a first slide rail distributed below the first mounting plate. A first through hole corresponding to the first cylinder is provided on the first mounting plate. The first slide rail is slidably connected with a sliding plate. The sliding plate is linked with a plurality of groups of pressing rod mechanisms. The plurality of groups of pressing rod mechanisms are arranged at intervals in sequence along the 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. The first cylinder can drive a group of pressing rod mechanisms to reciprocate along the axis of the first cylinder through the first through hole.

[0009] By adopting the above technical solution, multi-process assembly of the small brake assembly can be realized, without setting up multiple devices, nor repeatedly moving the product, facilitating the assembly of the small brake assembly, and improving production efficiency. The specific operation is as follows: Place the spring seat sleeve on the fixture by hand or a manipulator, place the threaded guide rod on a group of pressing rod mechanisms, and place the steel ball sleeve screw on another group of pressing rod mechanisms; the pressing rod mechanism with the threaded guide rod moves down to complete the pressing of the threaded guide rod; then the clamping device limits the threaded guide rod, so that even after the group of pressing rod mechanisms rises, the threaded guide rod will not bounce up under the action of the spring; next, the pressing rod mechanism with the steel ball sleeve screw moves down. After the steel ball sleeve screw reaches the predetermined position, this group of pressing rod mechanisms does not rise temporarily; then the riveting mechanism works to rivet the riveted edge on the outer periphery of the spring seat sleeve, and the steel ball sleeve screw is connected to the spring seat sleeve, and then the pressing rod mechanism rises. It can be directly seen from the specific operation that this technical solution does not require repeatedly moving the product, can realize multi-process pressing of the small brake assembly, does not require setting up multiple devices, nor repeatedly moving the product, facilitates the assembly of the small brake assembly, and improves production efficiency. And during the entire assembly process, the steel ball sleeve screw will not sway left and right or move up and down, and the threaded guide rod will not move up and down either.

[0010] The above-mentioned small brake assembly machine can be further configured as follows: the pressing rod mechanism includes a guide sleeve that is hollow inside and open at both ends. A number of groups of second through holes are provided on the sliding plate. The upper end of each group of guide sleeves is installed in a group of second through holes. A pressing rod is slidably connected inside the guide sleeve. A second telescopic spring is sleeved on the outer periphery of the pressing rod.

One end of the second telescopic spring is in contact connection with the second upper flange, and the other end is in contact connection with the second lower flange. The lower end of the pressing rod is linked with a clamping member capable of clamping materials.

[0011] With the above technical solution, through the cooperation of the guide sleeve and the second through holes on the sliding plate, the precise positioning of the pressing rod is achieved, ensuring the accuracy during the pressing process. Since the sliding plate can move along the first slide rail, and each guide sleeve can correspond to the first through hole, different pressing rod mechanisms can be quickly switched, improving work efficiency. The design of the second telescopic spring, the second upper flange, and the second lower flange ensures that the pressing rod can automatically reset after completing the pressing. The design of the guide sleeve with a hollow interior makes the device structure compact, occupies less space, and is convenient to be integrated into the existing production line. The specific operation is as follows: the sliding plate moves along the first slide rail driven by the second cylinder. Different guide sleeves will correspond to the second through holes, and only one group of guide sleeves corresponds to the first through hole at a time. The output end of the first cylinder passes through the first through hole to push the pressing rod downward. A clamping member for clamping materials is provided at the lower part of the pressing rod. After completing the pressing, the first cylinder resets, and the pressing rod will automatically reset under the action of the second telescopic spring.

[0012] The above-mentioned small brake assembly machine can be further configured as follows: a connecting hole is provided at the upper end of a group of clamping members. An insertion block matching the connecting hole is provided at the lower end of the pressing rod. A counterbore is provided at the lower end of the clamping member. A number of groups of notches are also provided at the lower end of the clamping member and are distributed at intervals on the outer periphery of the counterbore.

[0013] With the above technical solution, by providing the connecting hole and the insertion block, the detachable connection between the clamping member and the pressing rod can be achieved. The counterbore and the notches are further provided to facilitate the clamping member to clamp the threaded guide rod on the small brake assembly.

[0014] The above-mentioned small brake assembly machine can be further configured as follows: a connecting hole is provided at the upper end of a group of clamping members. An insertion block matching the connecting hole is provided at the lower end of the pressing rod. A cylindrical insertion hole is provided at the lower end of the clamping member. Guide insertion holes are also provided at the lower end of the clamping member and are distributed on the side of the cylindrical insertion hole.

[0015] By adopting the above technical solution, the detachable connection between the clamping member and the pressure rod can be realized by setting the connecting hole and the inserting block. Further, a cylindrical inserting hole is provided to facilitate the insertion of the rod portion of the steel ball sleeve screw; a guiding inserting hole is provided to position the steel ball sleeve screw during clamping, so as to facilitate the pressing and installation of the steel ball sleeve screw in the correct orientation.

[0016] The above-mentioned brake sub-assembly assembling machine can be further set as follows: a connecting hole is provided at the upper end of a set of clamping members, an inserting block matching with the connecting hole is provided at the lower end of the pressure rod, a riveting hole is provided at the lower end of the clamping member, and several groups of riveting blocks are evenly distributed in the riveting hole.

[0017] By adopting the above technical solution, the detachable connection between the clamping member and the pressure rod can be realized by setting the connecting hole and the inserting block. Further, a riveting block is provided to rivet the outer edge of the brake sub-assembly.

[0018] The above-mentioned brake sub-assembly assembling machine can be further set as follows: the clamping device includes a lower connecting member and motors distributed at the lower end of the lower connecting member, an internal threaded hole is provided at the upper end of the lower connecting member, a linkage sleeve is provided between the lower connecting member and the motors, the linkage sleeve is provided with a sliding hole penetrating along its own axis direction, guiding strip-shaped grooves are further provided on the linkage sleeve and distributed on the side of the sliding hole, the guiding strip-shaped grooves and the sliding hole are parallel to each other and communicate with each other, a plug pin is connected to the end of the lower connecting member, and the end of the plug pin extends into the guiding strip-shaped groove; the lower connecting member is slidably connected with the linkage sleeve through the sliding hole, the lower connecting member is coaxially rotated with the linkage sleeve through the plug pin and the guiding strip-shaped groove, and the lower connecting member is also linked with a reset assembly.

[0019] By adopting the above technical solution, when assembling the threaded guide rod, the threaded guide rod is pressed down onto the fixture by the pressing head device, and then the motor drives the lower connecting member to rotate. Since an internal threaded hole is provided on the lower connecting member, the lower end of the threaded guide rod will be threadedly connected with the lower connecting member, that is, the threaded guide rod is limited, and even if the pressing head device rises, the threaded guide rod will not bounce upward, which is convenient for the assembly of the steel ball sleeve screw. Further, by adding a linkage sleeve, a sliding hole, guiding strip-shaped grooves, and a plug pin, the rotational output form of the motor can be stably converted into the rotational form of the lower connecting member, and a certain degree of axial movement or self-adjustment is brought to the lower connecting member to adapt to the threaded connection mode between the lower connecting member and the threaded guide rod. The motor drives the linkage sleeve to rotate, and the lower connecting member rotates following the linkage sleeve under the action of the plug pin. Also, due to the threaded connection between the lower connecting member and the threaded guide rod, the lower connecting member can slide along the axis direction of the guiding strip-shaped groove relative to the linkage sleeve to adapt to the threaded connection mode between the lower connecting member and the threaded guide rod.

[0020] The above-mentioned small brake assembly machine can be further configured as follows: The reset assembly includes a first lower flange fixed to the end of the linkage sleeve, a first telescopic spring sleeved on the outer periphery of the lower connecting member, and a first upper flange fixed to the outer periphery of the lower connecting member.

[0021] With the above technical solution, during the sliding process of the lower connecting member relative to the linkage sleeve along the axis direction of the guiding strip groove, the first telescopic spring will be compressed. During the process of the lower connecting member disengaging from the threaded guide rod, the first telescopic spring helps the lower connecting member to reset, so as to perform the next assembly of the threaded guide rod.

[0022] The above-mentioned small brake assembly machine can be further configured as follows: The riveting mechanism includes a riveting head. One end of the riveting head is provided with a riveting block, and the other end is linked with a slider. The end of the riveting block is provided with an arc-shaped riveting edge. The slider is slidably connected to a second slide rail. One end of the slider is linked with a third air cylinder, and the third air cylinder can drive the riveting block to reciprocate along the axis direction of the second slide rail through the slider.

[0023] With the above technical solution, the third air cylinder can drive the riveting head to reciprocate along the second slide rail through the slider. The cooperation relationship between the slider and the second slide rail improves the movement stability of the riveting head, thereby ensuring the riveting accuracy. The riveting block is provided with an arc-shaped riveting edge, which can well adapt to the shape of the spring seat sleeve. The two ends of the riveting edge are used for riveting, and during the riveting process, the riveting block will not interfere with the spring seat sleeve.

The end face of the fixture e is also provided with 3 groups of stoppers e2 that surround the outer periphery of the placement hole e1. Each adjacent two groups of stoppers e2 are spaced apart and cooperate with the end face of the fixture e to form a set of grooves e3.

[0054] The pressing rod b9 mechanism equipped with the threaded guide rod moves down to complete the pressing of the threaded guide rod;

[0055] Then the clamping device c limits the threaded guide rod, so that even after the set of pressing rod b9 mechanisms rises, the threaded guide rod will not bounce up under the action of the spring;

[0056] Next, the pressing rod b9 mechanism equipped with the steel ball sleeve screw rod d8 moves down. After the steel ball sleeve screw rod d8 reaches the predetermined position, this set of pressing rod b9 mechanisms does not rise temporarily;

[0057] Immediately afterwards, the riveting mechanism d operates to rivet the riveting edge d4 on the outer periphery of the spring seat sleeve, and the steel ball sleeve screw d8 is connected to the spring seat sleeve. Then, the pressure rod b9 mechanism rises.
