Description

Technical Field

[0001] The invention relates to a vehicle brake caliper detection technology, and in particular to an automatic clamping device for brake caliper drag detection. Background Art

[0002] After brake boost, as the piston returns to its original position, the brake pad and disc continue to rub against each other, generating frictional torque known as drag torque. This has a certain impact on fuel consumption and brake noise. Therefore, it is necessary to test the drag torque of the brake caliper.

[0003] In the prior art, when performing brake caliper drag detection, manual clamping is used. Summary of the Invention

[0019] 4. A washer is connected between the tooling support plate and the locking screw to prevent the tooling support plate from being worn when the locking screw is tightened.

[0020] 5. The screw sleeve is fixed to the front of the tooling support plate with screws, and the locking screw is tightened by the screw sleeve to ensure sufficient thread length and locking strength.

[0021] 6. The rib plate connects the fixed base plate and the tooling support plate to increase the overall strength of the drag detection tooling.

[0022] 7. The floating spring is installed on the tightening gun to ensure that the tightening head has a floating amount when the tightening gun is running.

[0023] 8. A positioning column is provided on the first positioning plate of the drag detection tooling, and the second positioning plate of the automatic tightening mechanism is connected to the positioning column, so as to change the drag detection tooling corresponding to different products.

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Those skilled in the art will appreciate that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.

[0038] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. For example, terms such as "upper," "lower," "left," "right," "front," and "back" that indicate orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the disclosure. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as limiting the disclosure.

[0039] like Figures 1 to 6 As shown, a brake caliper clamping device for drag detection is used to detect the drag torque of the brake caliper 3, including a drag detection tool 1 installed on a drag detection workbench and an automatic tightening mechanism 2.

[0040] refer to Figures 2 to 4 As shown, the drag detection tool 1 includes a tool support plate 11 arranged vertically, a tool hardening pad 12 and a positioning bar 13 are installed behind the tool support plate 11, and a locking screw 14 is connected to the tool support plate 11.

[0041] Specifically, the tooling hardened pad 12 is installed on the tooling support plate 11 by screws and fits in with the brake caliper bracket mounting surface (the plane perpendicular to the mounting screw hole 31). The tooling hardened pad 12 can be made of die steel, such as cold-rolled die steel, which has high pressure resistance and wear resistance. The tooling hardened pad 12 is provided with a through hole corresponding to the locking screw 14. The positioning bar 13 is installed on the tooling support plate 11 by screws to support the brake caliper; the buffer 113 is installed on the positioning bar 13 and contacts the bottom of the brake caliper, playing a role of buffering and preventing bumps. The locking screw 14 will be fixed to the tooling support plate 11 by the screw sleeve 112, and the locking screw 14 tightens the brake caliper bracket mounting hole to fix the brake caliper 3.

[0042] Furthermore, positioning blocks 15 are provided on the left and right sides of the tool support plate 11 to limit the left and right positions of the brake caliper 3. The tool support plate 11 and the positioning blocks 15 are mounted on the fixed base plate 110 by screws to limit the front and rear and left and right distances of the brake caliper bracket.

[0043] In order to prevent the tool support plate 11 from being worn when the locking screw 14 is tightened, a washer 17 is connected between the tool support plate 11 and the locking screw 14 .

[0044] The tooling support plate 11 is installed on the fixed base plate 110 , and a rib plate 111 is connected between the tooling support plate 11 and the fixed base plate 110 . The rib plate 111 connects the fixed base plate 110 and the tooling support plate 11 to increase the overall strength of the drag detection tooling.

[0045] The drag detection tool 1 is mounted on a drag detection workbench. Specifically, a fixed base plate 110 is mounted on the workbench. A first positioning plate 16 is mounted on the fixed base plate 110 via pins and screws. This first positioning plate 16 is equipped with a positioning post 18, which is secured to the positioning plate 16 via a cylindrical washer 19 for connection to the automatic tightening mechanism 2.

[0046] The pin sleeve 115 is installed on the fixed base plate 110, and the fixed base plate 110 is installed on the drag detection workbench through the inspection fixture pin 114, so as to change the drag detection tool 1 corresponding to different products.

[0047] refer to Figure 5 and Figure 6 As shown, the automatic tightening mechanism 2 includes a tightening gun 27 and a telescopic cylinder 21. The tightening gun 27 drives the locking screw 14 to rotate, and the telescopic cylinder 21 drives the tightening gun 27 to move back and forth, thereby automatically screwing the locking screw 14 into the caliper bracket mounting screw hole 31, thereby achieving automatic clamping of the drag detection station.

[0048] Specifically, the cylinder push rod of the telescopic cylinder 21 is connected to the tightening gun 27 via a connecting plate 22. The tightening gun 27 is equipped with a tightening head 23, which is fixed to the locking screw 14 via a pin, allowing the tightening head 23 to drive the locking screw to rotate. The tightening head 23 is connected to a floating spring 26 that ensures a certain amount of floating when the tightening gun 27 is in operation. The tightening gun 27 is mounted on a mounting plate 25, to which a second positioning plate 24 is fixed. This second positioning plate 24 is connected to the positioning column 18, thereby connecting the automatic tightening mechanism 2 to the drag detection tool 1. The mounting plate 25 is mounted on the slide rail of the drag detection workbench.

[0049] Working principle: When the automatic tightening mechanism 2 operates normally, the telescopic cylinder 21 and the tightening gun 27 operate simultaneously. The tightening gun 27 drives the locking screw 14 in the drag detection tooling 1 to rotate, and the telescopic cylinder 21 drives the tightening gun 27 to move back and forth, thereby automatically screwing the locking screw 14 into the caliper bracket mounting screw hole 31, achieving automatic clamping of the drag detection station.

[0050] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the above specific embodiment. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
