Description

Technical Field

[0001] The utility model relates to the technical field of brake pad installation tools, in particular to an assembly device for a small brake pad. Background Art

[0002] Brake pads are important components of vehicle braking systems. They are mainly used in conjunction with brake discs to provide braking capabilities for the vehicle.

[0003] When the brake pad is in use, it is often stuck on the brake disc, and there is a protective cover structure on the outside, which is an arc-shaped concave structure. The brake pad is installed in this concave structure. Whether it is during maintenance, replacement or manufacturer's manufacturing process, the brake pad needs to be installed in the concave shell.

[0004] In the process of installing the brake pad, the tools used are relatively simple, a simple screwdriver can be used, but after the brake pad is installed, the remaining space on the inner wall of the concave shell is almost the same as the thickness of the brake disc, that is, the space reserved for installing the brake pad is limited. When installing, the screwdriver tool cannot remain vertical to the inner wall of the concave shell. First of all, during installation, it is easy to cause angular deviation of the installed bolt fasteners, and they are located inside the shell and cannot be seen intuitively, so the fasteners will be offset and tilted, which will not be well installed, affecting subsequent use. At the same time, it will directly affect the braking effect of the brake pad when it is used. Secondly, it is impossible to remove it accurately and quickly during maintenance and replacement.

[0005] Therefore, we propose a small brake pad assembly device to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides a technical solution for an assembly device of a small brake pad:

[0022] Example:

[0023] The device mainly includes a transmission box 1, a handle 2 is installed on the left side of the bottom of the transmission box 1 through a fastener, a drive shaft 3 is installed through the left side of the inner cavity of the transmission box 1, and a screwdriver head 4 is installed through the right side of the inner cavity of the transmission box 1.

[0024] A first gear 5 is mounted on the outer ring of the driving shaft 3 , and a second gear 6 is mounted on the outer ring of the screwdriver head 4 .

[0025] The transmission box 1 is a hollow box design, and the front and back are both open designs, and the thickness of the transmission box 1 is less than 1 cm. First of all, the transmission box 1 adopts the open front and back design, mainly to facilitate the addition of lubricating oil to the first gear 5 and the second gear 6, and also to observe the status of the two gears. The transmission box design with a thickness of less than 1 cm is mainly to meet the size of the inner cavity space for installing the brake pad housing, so that it is convenient to penetrate into the installation space.

[0026] The first gear 5 and the second gear 6 are meshed with each other, and the thickness of the two is the same as the height of the inner cavity of the transmission box 1, both within 1 cm.

[0027] The handle 2 is a hollow column structure, a small motor 7 is installed in the middle of the inner cavity of the handle 2, and a battery structure 8 is installed at the bottom of the inner cavity of the handle 2.

[0028] The output shaft of the small motor 7 is docked with the bottom of the driving shaft 3, and the battery structure 8 is electrically connected to the small motor 7 through a wire and a switch button.

[0029] The outer ring of the driving shaft 3 and the outer ring of the cylindrical part of the screwdriver head 4 are both provided with bearing structures, and the bearing structures are installed on the transmission box 1 .

[0030] In this embodiment, when installing the brake pad, first place the brake pad on the corresponding position of the concave shell, then adsorb the fastener through the magnetic screwdriver head 4, then insert the entire transmission box 1 together with the fastener structure into the concave shell, and observe from the side that the fastener reaches the mounting hole position, then insert the fastener into the mounting hole, connect the small motor 7 and the battery structure 8, and start the small motor 7. Its output shaft drives the drive shaft 3 to rotate, and the drive shaft 3 drives the first gear 5 to rotate, and the first gear 5 drives the second gear 6 to rotate. When the second gear 6 rotates, it directly drives the screwdriver head 4 thereon to rotate, so that the fastener can be installed at the best angle, that is, the brake pad is installed and fixed at the best angle. The fastener structure required for the installation of the entire brake pad is installed using the above steps. When repairing and replacing, the small motor 7 can be operated to rotate in the opposite direction to remove it.
