Description

Technical Field

[0001] The present invention belongs to the technical field of brake production equipment. Specifically, the present invention relates to a fixture for assembling brake springs. Background Art

[0002] At present, with the increasing requirements for automobile fuel consumption, the requirements for brake drag are also getting higher and higher. A spring is installed on a disc brake caliper. The spring is an eight-shaped spring, and using an eight-shaped spring can effectively reduce the drag effect. During the assembly process of the brake, since the eight-shaped spring is in a compressed state, the spring force generated by the eight-shaped spring will cause the friction lining to pop outwards.

[0003] Therefore, during the assembly or replacement of the eight-shaped spring, it is necessary for the operator to constantly clamp the eight-shaped spring by hand to keep the eight-shaped spring in a compressed state. Such an operation method is time-consuming and laborious, with low assembly efficiency and relatively high labor intensity. Summary of the Invention

After the outer friction lining and the inner friction lining approach each other, the brake spring connected to the outer friction lining and the inner friction lining is in a compressed state.

[0006] The first force transmission structural member is slidably connected to the second force transmission structural member.

[0007] A convex platform is provided on the first force transmission structural member, and a chute for the convex platform to be embedded is provided on the second force transmission structural member.

[0028] As Figures 1 to 8 shown, the present invention provides a fixture for assembling a brake spring, including a first force transmission structural member 1 for applying pressure to the inner friction plate of the brake, a second force transmission structural member 2 connected to the first force transmission structural member 1 and for applying pressure to the inner friction plate of the brake, and a pressing mechanism cooperating with the first force transmission structural member 1 and the second force transmission structural member 2 and for applying a pressure to the outer friction plate of the brake to make it move towards the inner friction plate. After the outer friction plate and the inner friction plate approach each other, the brake spring connected to the outer friction plate and the inner friction plate is in a compressed state.

[0029] Specifically, as Figure 3 and Figure 4 shown, the brake mainly includes a caliper body, a bracket, an inner friction plate, an outer friction plate and a brake spring. The brake spring is a figure-eight spring. Two brake springs are provided. The brake spring is connected to the inner friction plate and the outer friction plate. The brake spring applies an elastic force to the inner friction plate and the outer friction plate. The brake spring is used to realize the reset of the inner friction plate and the outer friction plate when the brake releases the brake.

[0030] As Figure 1 and Figure 2As shown in the figure, the first force transmission structure member 1 and the second force transmission structure member 2 are U-shaped structures. The open ends of the first force transmission structure member 1 and the second force transmission structure member 2 face each other. The first force transmission structure member 1 and the second force transmission structure member 2 are on the same straight line parallel to the first direction. The first force transmission structure member 1 and the second force transmission structure member 2 are slidably connected. A boss 10 is provided on the first force transmission structure member 1, and a chute for the boss 10 to be embedded is provided on the second force transmission structure member 2. The shape of the boss 10 matches the shape of the chute. The boss 10 is provided at one end (connection end) of the first force transmission structure member 1. The length direction of the boss 10 is parallel to the first direction. The other end (compression end) of the first force transmission structure member 1 is used to contact the inner friction plate. The chute is a long groove provided at one end (connection end) of the second force transmission structure member 2. The length direction of the chute is parallel to the first direction. The other end (compression end) of the second force transmission structure member 2 is used to contact the inner friction plate.

[0031] As Figure 1 and Figure 2 shown in the figure, in this embodiment, two bosses 10 are provided. The two bosses 10 are on the same straight line perpendicular to the first direction. The number of chutes is the same as the number of bosses 10, and each boss 10 is respectively embedded in a chute. The distance between the first force transmission structure member 1 and the second force transmission structure member 2 is adjustable. When the first force transmission structure member 1 and the second force transmission structure member 2 move relative to each other along the first direction, the boss 10 cooperates with the chute to play a guiding role. The distance between the compression end of the first force transmission structure member 1 and the compression end of the second force transmission structure member 2 is adjustable, which can meet the assembly requirements of brakes of different sizes and improve the versatility.

[0032] As Figure 1 and Figure 2 shown in the figure, the pressing mechanism includes a push rod 3 for contacting the outer friction plate. A first avoidance hole 5 for the push rod 3 to pass through is provided on the first force transmission structure member 1, and a second avoidance hole 6 for the push rod 3 to pass through is provided on the second force transmission structure member 2. Both the first avoidance hole 5 and the second avoidance hole 6 are round holes. The axes of the first avoidance hole 5 and the second avoidance hole 6 are parallel to the second direction, and the second direction is perpendicular to the first direction. The two bosses 10 are on the same straight line parallel to the third direction, and the third direction is perpendicular to the first direction and the second direction. A plurality of first avoidance holes 5 and second avoidance holes 6 are provided. All the first avoidance holes 5 are on the same straight line parallel to the first direction, and all the second avoidance holes 6 are also on the same straight line parallel to the first direction.

[0033] As Figure 1 and Figure 2 shown in the figure, three first avoidance holes 5 and three second avoidance holes 6 are provided respectively.

[0034] As Figure 1 , Figure 2 andFigure 8 As shown, the pressing mechanism further includes a handle 4 connected to the push rod 3. A locking pin 9 is provided on the handle 4, a limiting block 7 is provided on the second force transmission structural member 2, and a locking groove 8 for the locking pin 9 to be inserted into is provided on the limiting block 7. The length direction of the push rod 3 is parallel to the second direction. One end (pressing end) in the length direction of the push rod 3 is in contact with the outer friction plate, and the other end in the length direction of the push rod 3 is connected to the handle 4. The handle 4 and the push rod 3 are threadedly connected, which is convenient for disassembly and assembly. The locking pin 9 is fixedly connected to the handle 4 and extends outward from the handle 4. The end of the push rod 3 is provided with an external thread, and the end of the handle 4 is provided with an internal threaded hole for the end of the push rod 3 to be inserted into. The connection end of the first force transmission structural member 1 is located between the connection end of the second force transmission structural member 2 and the handle 4. The limiting block 7 is fixedly connected to the connection end of the second force transmission structural member 2. The locking groove 8 is a groove provided on the surface of the limiting block 7. The length direction of the locking groove 8 is parallel to the first direction. A plurality of locking grooves 8 are provided, and all the locking grooves 8 are on the same straight line parallel to the second direction. The locking pin 9 can be selectively inserted into the locking grooves 8 at different positions, so as to realize the adjustable position of the push rod 3, and further realize the adjustment of the compression amount of the brake spring, improving the versatility.

[0035] When using the fixture with the above structure, the assembly process is as follows:

[0036] Step 1: Connect the first force transmission structural member 1 and the second force transmission structural member 2 together, with the boss 10 inserted into the sliding groove. Then, according to the specific specifications of the brake caliper, move the first force transmission structural member 1 and the second force transmission structural member 2 to adjust the distance between the pressing end of the first force transmission structural member 1 and the pressing end of the second force transmission structural member 2 to an appropriate range;

[0037] Step 2: Select a suitable position and pass the push rod 3 through the aligned first avoidance hole 5 and second avoidance hole 6;

[0038] Step 3: Install the handle 4 on the push rod 3.

[0039] As Figure 5 and Figure 6As shown, when assembling the brake, first connect the brake spring with the outer friction plate and the inner friction plate. After adjusting to fit different specifications of the brake caliper, make the fixture parallel to the brake caliper. Respectively, press the pressing ends of the first force transmission structural member 1 and the second force transmission structural member 2 against the inner friction plate of the brake caliper. The operator's hands respectively hold the first force transmission structural member 1, the second force transmission structural member 2, and the handle 4. Then, push the handle 4 along the second direction until the push rod 3 contacts the outer friction plate of the brake caliper. Continue to push the handle 4 until the brake spring is in a compressed state. When the operator pushes the push rod 3 to a suitable position, rotate the handle 4 and rotate the locking pin 9 on the handle 4 into a locking groove 8 to complete the locking. The first force transmission structural member 1, the second force transmission structural member 2, and the push rod 3 remain stationary, thereby enabling the brake spring to remain in a compressed state. Then, the operator can continue with the assembly work of the remaining components of the brake.

[0040] For the fixture with the above structure, without affecting the assembly of the brake caliper, it uses a simple mechanical structure with an automatic locking function to fix the eight-shaped spring, releasing both hands and having simple operation, which helps to improve the beauty of the assembly work. This fixture can be adjusted to fit different specifications of the brake caliper, and is convenient for installation and disassembly, with good versatility.

[0041] The present invention has been described exemplarily above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
