Description

Technical Field

[0001] This utility model relates to the field of brake pad tooling technology, and in particular to a brake pad forming and positioning tooling. Background Technology

[0002] Brake pads consist of a friction substrate and a brake pad steel backing. The friction substrate and the brake pad steel backing are usually installed with glue. After the glue installation is completed, the friction substrate and the brake pad steel backing need to be further pressed on a press, which requires the use of brake pad forming and positioning fixtures.

[0003] An existing patent (publication number: CN219587921U) discloses a brake pad forming and positioning fixture, including a fixture base plate and a fixture pressure plate mounted on the fixture base plate. The fixture base plate and the fixture pressure plate are respectively provided with a number of placement grooves and brake pad positioning grooves. The friction substrate is placed in the placement groove of the fixture base plate, and the brake pad steel back to be pressed is placed on the corresponding friction substrate. Then, the mounting holes on the fixture pressure plate are installed on the support rod on the fixture base plate, so that the rubber pad in the brake pad positioning groove on the fixture pressure plate directly contacts the brake pad steel back. The brake pad steel back is positioned by the brake pad positioning groove, and then placed on the worktable of the press. During pressing, the pressure on the press is directly applied to the fixture pressure plate to press the friction substrate and the brake pad steel back. In the process of implementing this solution, the following problems were found in the existing technology, which have not been well resolved: The above device positions the tooling plate and the tooling base plate by connecting the mounting hole and the support rod. However, different brake pads have different heights. When the brake pad to be pressed is high, after the brake pad is placed inside the tooling plate and the tooling base plate, it is difficult for the mounting hole and the support rod to connect the tooling plate and the tooling base plate. As a result, the tooling plate and the tooling base plate are prone to misalignment during the pressing of the brake pad, which can easily lead to damage to the brake pad. Utility Model Content

[0004] To address the aforementioned issue where, when the brake pads to be press-fitted are of high height, placing the brake pads inside the tooling plate and tooling base plate makes it difficult to connect the tooling plate and tooling base plate with the mounting holes and support rods, leading to misalignment of the tooling plate and tooling base plate during the brake pad press-fitting process and consequently damage to the brake pads, this utility model provides a brake pad forming and positioning tooling.

[0005] This utility model provides a brake pad forming and positioning fixture, which adopts the following technical solution:

[0006] A brake pad forming and positioning fixture includes a fixture base, four connecting strips are fixedly provided on the top of the fixture base, a fixture pressure plate is movably sleeved on the upper side of the four connecting strips, and movable plates are fixedly provided on the front and rear sides of the bottom of the fixture pressure plate.

[0007] The tooling base has sliding grooves on both the front and rear sides of the top, which are slidably engaged with the moving plate. The tooling base also has L-shaped grooves on both the left and right sides, and limiters are slidably arranged inside the L-shaped grooves.

[0008] The above technical solution facilitates accurate and stable pressing of the brake pads using the tooling base and tooling pressure plate, thereby reducing the possibility of damage to the brake pads during the pressing process. It also reduces the possibility of the tooling pressure plate shifting when it moves towards the lower side of the tooling base.

[0009] Optionally, in the above-mentioned brake pad forming and positioning fixture, the connecting strip is T-shaped, and a rectangular groove is provided inside the transverse groove of the T-shaped connecting strip.

[0010] The above technical solution facilitates the inner fit of the rectangular groove with the horizontal bar of the L-shaped strip, thus preventing the tooling pressure plate from shifting when it moves on the upper side of the tooling base.

[0011] Optionally, in the above-mentioned brake pad forming and positioning fixture, the limiting component includes two L-shaped plates, which are slidably disposed inside two L-shaped grooves. A compression spring is fixedly disposed on the side of the vertical plate of the L-shaped plate, and one end of the compression spring is fixedly engaged with the inside of the L-shaped groove. An L-shaped strip is fixedly disposed on the upper side of the two horizontal plates of the two L-shaped plates, and the side of the horizontal strip of the L-shaped strip is slidably engaged with the inside of the rectangular groove.

[0012] The above technical solution facilitates the L-shaped strip to easily mate and install the tooling base with the tooling pressure plate.

[0013] Optionally, in the above-mentioned brake pad forming and positioning fixture, the fixture pressure plate has through slots on both the left and right sides, and the height inside the through slots is equal to the height of the rectangular slot.

[0014] The above technical solution ensures that the through grooves and rectangular grooves of equal height will not obstruct the horizontal bars of the L-shaped strip, thus preventing the tooling pressure plate from sliding on the tooling base with limited height.

[0015] Optionally, in the above-mentioned brake pad forming and positioning fixture, the length of the vertical groove of the L-shaped groove is equal to the width of the rectangular groove and the through groove.

[0016] The above technical solution facilitates the movement of the horizontal bar of the L-shaped strip out of the rectangular groove and through groove after the vertical plate of the L-shaped plate is moved to fit against the side of the inner wall of the vertical groove of the L-shaped groove.

[0017] Optionally, in the above-mentioned brake pad forming and positioning fixture, a hard rubber sheet is fixedly provided on the top of the fixture base and the bottom of the fixture pressure plate.

[0018] The above technical solution helps to reduce the possibility of squeezing damage between the tooling base and the tooling pressure plate by using a rigid rubber sheet.

[0019] Optionally, in the above-mentioned brake pad forming and positioning fixture, the fixture base is in the shape of an isosceles trapezoid, and silicone pads are embedded at the four corners of the bottom of the fixture base.

[0020] The above technical solution facilitates the use of silicone pads and isosceles trapezoidal tooling bases, resulting in better stability of the tooling bases.

[0021] Optionally, in the above-mentioned brake pad forming and positioning fixture, mounting grooves are provided at the four corners of the top of the fixture pressure plate, and the interior of the mounting grooves slides in conjunction with the interior of the connecting strip.

[0022] The above technical solution facilitates the easy movement of the tooling pressure plate to the upper side of the connecting strip via the mounting groove, and ensures the accuracy of the position of the tooling pressure plate and the tooling base.

[0023] In summary, this utility model has at least one of the following beneficial effects:

[0024] Place the brake pads to be pressed onto the fixture base, move the two L-shaped plates to the sides to compress the compression springs, causing the L-shaped plates to move the L-shaped strips out of the rectangular grooves. Align the four mounting slots on the upper side of the fixture pressure plate with the four connecting strips and move it down, so that the upper side of the brake pads is clamped by the inside of the fixture pressure plate. Release the L-shaped plates, allowing them to move the L-shaped strips into the mounting slots. This allows the fixture base and fixture pressure plate to accurately and stably limit the pressing of the brake pads, thereby reducing the possibility of damage to the brake pads during the pressing process.

[0025] The press machine exerts downward pressure on the tooling plate, causing it to press the brake pads into place. Simultaneously, the tooling plate moves two movable plates towards the lower side of the inner wall of the two movable slots. The L-shaped bar limits the movement of the through slot, ensuring that the tooling plate moves vertically and stably downwards, thus reducing the possibility of deviation when the tooling plate moves towards the lower side of the tooling base.

[0030] The following is combined with Figure 1-3 The present invention will be described in further detail below.

[0031] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a brake pad forming and positioning fixture, including a fixture base 1, four connecting strips 2 are fixedly arranged on the top of the fixture base 1, a fixture pressure plate 3 is movably sleeved on the upper side of the four connecting strips 2, and movable plates 4 are fixedly arranged on the front and rear sides of the bottom of the fixture pressure plate 3.

[0032] The tooling base 1 has sliding grooves 5 on both the front and rear sides of the top, which are slidably engaged with the sliding plate 4. The tooling base 1 has L-shaped grooves 6 on both the left and right sides, and limiters 7 are slidably arranged inside the L-shaped grooves 6.

[0033] Tooling principle: When using this brake pad forming and positioning tooling, first place the brake pad to be pressed on the upper side of the tooling base 1. Then, move the two L-shaped plates 701 to the left and right sides respectively to compress the compression spring 702, so that the L-shaped plates 701 drive the L-shaped strips 703 to move out of the rectangular groove 201. Next, align the four mounting grooves 302 on the upper side of the tooling pressure plate 3 with the four connecting strips 2 and move them downwards, so that the upper side of the brake pad is clamped inside the tooling pressure plate 3. Then, release the L-shaped plates 701, so that the L-shaped plates 701 drive the L-shaped strips 703 to move from the through groove 301 to the mounting groove 302. Thus, the tooling base 1 and the tooling pressure plate 3 can accurately and stably limit the brake pad for pressing, thereby reducing the possibility of damage to the brake pad during the pressing process.

[0034] During the pressing process of brake pads, the pressing machine pushes downwards, causing the tooling plate 3 to generate downward pressure, which in turn pushes the brake pads downwards. At the same time, the tooling plate 3 moves the two moving plates 4 to the lower side of the inner wall of the two moving grooves 5. The horizontal bar of the L-shaped strip 703 limits the through groove 301, so that the tooling plate 3 can move vertically and stably downwards, thereby reducing the possibility of the tooling plate 3 deviating when it moves downwards towards the tooling base 1.

[0035] It should be noted that the connecting strip 2 is T-shaped, and the horizontal groove of the T-shaped connecting strip 2 has a rectangular groove 201 inside.

[0036] By adopting the above technical solution, the rectangular groove 201 can cooperate with the inner side of the horizontal bar of the L-shaped bar 703, so that the tooling pressure plate 3 will not shift when it moves on the upper side of the tooling base 1.

[0037] It should be further explained that the limiting member 7 includes two L-shaped plates 701, which are slidably disposed inside the two L-shaped grooves 6 respectively. A compression spring 702 is fixedly disposed on the side of the vertical plate of the L-shaped plate 701, and one end of the compression spring 702 is fixedly engaged with the inside of the L-shaped groove 6. An L-shaped strip 703 is fixedly disposed on the upper side of the two horizontal plates of the two L-shaped plates 701, and the side of the horizontal strip of the L-shaped strip 703 is slidably engaged with the inside of the rectangular groove 201.

[0038] Using the above technical solution, the L-shaped strip 703 facilitates the installation of the tooling base 1 and the tooling pressure plate 3.

[0039] It should be noted that the tooling pressure plate 3 has through slots 301 on both the left and right sides, and the height inside the through slots 301 is equal to the height of the rectangular slots 201.

[0040] Using the above technical solution, the through groove 301 and the rectangular groove of equal height will not obstruct the horizontal bar of the L-shaped strip 703, thus preventing the tooling pressure plate 3 from sliding on the tooling base 1 with limited height.

[0041] It should be noted that the length of the vertical groove inside the L-shaped groove 6 is equal to the width inside the rectangular groove 201 and the through groove 301.

[0042] Using the above technical solution, when the vertical plate of the L-shaped plate 701 is moved to fit against the side of the inner wall of the vertical groove of the L-shaped groove 6, the L-shaped plate 701 can drive the horizontal bar of the L-shaped strip 703 to move out from the inside of the rectangular groove 201 and the through groove 301.

[0043] It should be noted that both the top of the tooling base 1 and the bottom of the tooling pressure plate 3 are fixedly fitted with hard rubber sheets.

[0044] By adopting the above technical solution, the hard rubber sheet reduces the possibility of squeezing damage between the tooling base 1 and the tooling pressure plate 3.

[0045] It should be noted that the tooling base 1 is an isosceles trapezoid, and silicone pads are embedded at the four corners of the bottom of the tooling base 1.

[0046] By adopting the above technical solution, the silicone pad and the isosceles trapezoidal tooling base 1 make the tooling base more stable.

[0047] It should be noted that the tooling pressure plate 3 has mounting grooves 302 at the four corners of its top, and the interior of the mounting grooves 302 slides in conjunction with the interior of the connecting strip 2.

[0048] By adopting the above technical solution, the tooling pressure plate 3 can be easily moved to the upper side of the connecting strip 2 through the mounting groove 302, and the accuracy of the position of the tooling pressure plate 3 and the tooling base 1 can be ensured.

[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
