[0028] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0029] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Furthermore, the terms "first," "second," "third," "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] The terms “connection,” “connected to,” or any other variations are intended to encompass various relative positions where a connection exists, including both direct and indirect connections. A direct connection can be formed through a pneumatic conduit, while an indirect connection can be formed through devices such as valves or sensors, through pneumatic components such as brake control units, or through any other medium such as air.

[0031] Please see Figure 1-2 This is a schematic diagram of the structure of a brake caliper processing fixture 100 provided in an embodiment of the present utility model. In the following text, for the purpose of making the description more concise, the brake caliper processing fixture 100 may also be referred to as fixture 100.

[0032] In one embodiment, the brake caliper machining fixture 100 includes a mounting frame 10. The mounting frame 10 has a back surface 101 and an operating surface for machining the brake caliper. The back surface 101 is a vertical surface, and the operating surface is parallel to the back surface 101. The mounting frame 10 has a vertical structure, and the back surface is a vertical surface. It can be understood that the operating surface is a defined virtual surface. In the actual machining process, the fixture 100 holds the brake caliper, and the tool of the external four-axis machining center usually performs horizontal and vertical movements to machine the brake caliper. At this time, the mounting frame 10 must have an operating surface on which the tool performs milling, drilling, and other machining operations on the brake caliper.

[0033] It should be noted that the external machining center involved in this case, that is, the machine tool, is a horizontal four-axis machining center. The corresponding tool works along the vertical plane to form a vertical working surface. In other words, the operating surface matches it to form a vertical plane.

[0034] From the perspective of the brake caliper, the operating surface can also be called the surface to be machined. In this case, in order to match the external four-axis machining center, when the brake caliper is installed and fixed on the fixture 100, the surface to be machined of the brake caliper must be kept vertical. In other words, the surface to be machined of the brake caliper needs to be parallel to the back side.

[0035] In one embodiment, the brake caliper processing fixture 100 includes several pairs of clamping devices 20. The clamping devices 20 are disposed on the side of the mounting frame 10 away from the back side, which means that they are arranged on the side of the operating surface to enable the processing operation of the brake caliper on the operating surface.

[0036] Each pair of clamping devices 20 is arranged symmetrically along the second direction. Each pair of clamping devices is used to clamp the left brake caliper and the right brake caliper, respectively. It can be understood that brake calipers are used in the field of wheel braking and usually include a pair of left brake calipers and right brake calipers. A pair of brake calipers can be a left brake caliper and a right brake caliper. Therefore, the corresponding pair of clamping devices 20 should also include a left clamping device and a right clamping device.

[0037] A plurality of clamping devices 20 are arranged along a first direction, which is perpendicular to a second direction and parallel to the back surface. Specifically, the first direction is a vertical direction, the second direction is a horizontal left-right direction, and the plurality of clamping devices 20 are arranged in an array along the first and second directions, with the first and second directions both located on a vertical plane.

[0038] It can be seen that the two clamping devices 20 located in the same row along the second direction should be left and right clamping devices, and should be symmetrical. The two clamping devices 20 located in the same column along the first direction should be two left clamping devices or two right clamping devices.

[0039] In other embodiments, the first direction may be a horizontal left-right direction and the second direction may be a vertical direction. In this case, the two clamping devices located in the same row along the first direction should be two left clamping devices or two right clamping devices, and the two clamping devices 20 located in the same column along the second direction should be left-right clamping devices, or they can be arranged in pairs.

[0040] The clamping device 20 includes a positioning unit 30 for clamping the brake caliper and a positioning surface 201 for engaging with the flange face of the brake caliper. The positioning surface 201 forms a first acute angle α with the operating surface, and the opening direction of the first acute angle α faces a first direction. In other words, the positioning surface 201 forms a first acute angle α with the vertical surface.

[0041] It is understood that the opening of the first acute angle α is an angular range. In this case, the fact that the opening direction of the first acute angle α faces the first direction does not mean that the opening direction of the first acute angle α is completely parallel to the first direction. When the first direction is vertical, it means that the opening of the first acute angle α faces upward or downward, specifically it can be tilted upward or tilted downward. In other embodiments, when the first direction is left-right, it means that the opening of the first acute angle α faces left or right, specifically it can be tilted left or tilted right.

[0042] Specifically, the brake caliper must be fixed to the fixture 100 by the positioning unit 30. When fixing, it is necessary to ensure that the surface to be processed of the brake caliper is vertical. When the flange of the brake caliper has a torsion angle, the flange surface is formed as an inclined surface. In order to achieve a better fit for the positioning of the brake caliper, the positioning surface 201 that mates with the flange surface is also set as an inclined surface. It can be understood that the inclination angle of the positioning surface 201 should be consistent with the inclination angle of the flange surface.

[0043] Specifically, when the flange is twisted upwards or downwards, an angle is formed between the flange face and the vertical plane, and the opening of the angle is tilted upwards or downwards. In other words, combined with... Figure 3-4 As shown, the first direction is the vertical direction, and the positioning surface 201 and the operating surface have a first acute angle α, that is, the positioning surface 201 has a slope in the vertical direction.

[0044] In other embodiments, when the flange is twisted to the left or right, an angle is formed between the flange face and the vertical face, and the opening of the angle is tilted to the left or to the right. In other words, the first direction is a horizontal left-right direction, and the positioning surface 201 forms a first acute angle α with the first direction, that is, the positioning surface 201 has a slope along the horizontal direction.

[0045] All of the above are to ensure that the tilt angle and direction of the positioning surface 201 are adapted to the tilt angle and direction of the flange surface. In a specific embodiment, the first direction a is the vertical direction.

[0046] Thus, the fixture 100 is designed with an angle-compensated positioning surface 201 based on the flange face angle of the brake caliper product. The tilt angle of the positioning surface 201 is the same as the angle of the brake caliper flange face, ensuring that the surface to be machined on the brake caliper is within the working plane of the machining center, which can meet the planar machining requirements of a horizontal four-axis machining center. More specifically, this invention is designed for a four-axis horizontal machining center, and the fixture 100 includes two pairs of clamping devices 20.

[0047] In one embodiment, a second acute angle is formed between the positioning surface 201 and the operating surface, and the opening direction of the second acute angle faces a second direction. In other words, a second acute angle is formed between the positioning surface 201 and the vertical surface.

[0048] It is understood that the opening of the second acute angle is an angular range. In this case, the fact that the opening direction of the second acute angle faces the second direction does not mean that the opening direction of the second acute angle is completely parallel to the second direction. When the second direction is vertical, it means that the opening of the second acute angle faces upward or downward, specifically it can be tilted upward or tilted downward. In other embodiments, when the first direction is left-right, it means that the opening of the second acute angle faces left or right, specifically it can be tilted left or tilted right.

[0049] It is understandable that when the flange has two torsion angles, the positioning surface 201 adapts to the flange face simultaneously having two tilt angles. Continuing with... Figure 5-6 As shown in Figures 1 and 10, when the second direction is the left and right direction, the positioning surface 201 also has a slope along the horizontal left and right direction.

[0050] In this specific embodiment, the positioning surface 201 and the operating surface have a first acute angle α and a second acute angle. The first direction is the vertical direction, and the angle value of the first acute angle α ranges from 10° to 15°, more specifically 12°. The second direction is the left-right direction, and the angle value of the second acute angle ranges from 2° to 5°, more specifically 2°.

[0051] More specifically, in combination Figure 1 , 3 As shown in Figure 5, a pair of clamping devices 20 are symmetrically arranged along a second direction, and a pair of positioning surfaces 201 are symmetrically arranged. Each positioning surface 201 has a slope in the vertical direction and a slope in the horizontal direction. The two pairs of clamping devices 20 are arranged along a first direction, including two left positioning surfaces 201 arranged along the first direction on the left side and two right positioning surfaces 201 arranged along the first direction on the right side.

[0052] In one embodiment, the clamping device 20 includes a positioning plate 21, and the positioning surface 201 is disposed on the positioning plate 21. The clamping device 20 includes a plurality of positioning points disposed on the outer periphery of the positioning surface 201. The positioning points adopt a small area and multiple points design. The brake caliper is ground as a whole, which can ensure the flatness accuracy of the positioning surface 201 and reduce the risk of iron filings and foreign objects that are easy to exist in the large positioning area, causing the brake caliper positioning surface to be bumped, dented, or poorly processed.

[0053] The mounting frame 10 includes an inclined mounting surface 102, and the positioning plate 21 is inclinedly mounted on the mounting surface 102. The mounting surface 102 has a third acute angle b with respect to the vertical surface. The first acute angle a and the third acute angle b have parallel opening directions and the same angle value. More specifically, the mounting surface 102 has a third acute angle b with respect to the first direction.

[0054] Combination Figure 7 As shown, the mounting frame 10 includes a first horizontal plate and a second horizontal plate disposed opposite to each other, and a first vertical plate 11 and a second vertical plate 12 connecting the first horizontal plate and the second horizontal plate. The first horizontal plate and the second horizontal plate, the first vertical plate 11 and the second vertical plate 12 together enclose at least one mounting space for mounting at least one clamping device 20. The mounting frame 10 encloses at least two mounting spaces arranged in an array for mounting at least two mounting units 20.

[0055] The first vertical plate 11 and the second vertical plate 12 include the mounting surface 102. The positioning plate 21 is installed obliquely on the mounting surface, so that the positioning surface 201 and the operating surface form a first acute angle α. It can be understood that when the positioning plate 21 is not installed, it itself has no slope in the vertical direction. It is because it is installed obliquely on the mounting frame 10 that the positioning surface 201 and the vertical surface form an angle.

[0056] The positioning plate 21 includes a positioning plate back surface 210 disposed opposite to the positioning surface 201. The positioning plate back surface 210 is parallel to the positioning surface and is a vertical surface. A fourth acute angle c is formed between the positioning plate back surface 210 and the positioning surface 201. The second acute angle and the fourth acute angle c have parallel opening directions and the same angle value. Figure 8-10 As shown, the positioning surface 201 of the positioning plate 21 itself has a slope in the horizontal direction.

[0057] In one embodiment, the positioning unit 30 includes a first positioning pin 31 and a second positioning pin 32 located on both sides of the positioning surface 201. The first positioning pin 31 and the second positioning pin 32 are connected to the positioning plate 21 by means of contouring, countersunk hole and bolt connection, which makes the positioning accurate and the replacement convenient and quick.

[0058] The first positioning pin 31 and the second positioning pin 32 have different diameters and structures. Since brake caliper products are divided into left and right parts, the first positioning pin 31 and the second positioning pin 32 of the left and right brake calipers have different dimensions and structures. A single positioning plate 21 can only match one brake caliper, which can prevent the left and right brake caliper parts from being installed backwards and play an effective role in preventing errors.

[0059] The first positioning pin 31 is fixed to the positioning plate 21 by the first mounting plate 311. The clamping device 20 includes a first gasket 312 located between the first mounting plate 311 and the positioning plate 21. The first gasket 312 and the first mounting plate 311 are detachably disposed. Thus, the first gasket 312 can be replaced as needed.

[0060] Specifically, at least one first shim 312 is located between the first mounting plate 311 and the positioning plate 21 along the second direction. The thickness of the first shim 312 affects the distance between the first positioning pin 31 and the second positioning pin 32 along the second direction. The distance between the first positioning pin 31 and the second positioning pin 32 can be adjusted by replacing the first shim 312 with one of different thicknesses, making it suitable for brake caliper products of different sizes.

[0061] Specifically, at least one first shim 312 is located between the first mounting plate 311 and the positioning plate 21 along the first direction. The thickness of the first shim 312 affects the position of the first positioning pin 31 along the first direction. The position of the first positioning pin 31 along the first direction can be adjusted by replacing the first shim 312 with one of different thicknesses, making it suitable for brake caliper products with different structures.

[0062] As described above, the second positioning pin 32 is fixed to the positioning plate 21 by the second mounting plate 321. The clamping device 20 includes a second gasket 322 located between the second mounting plate 321 and the positioning plate 21. The second gasket 322 and the second mounting plate 321 are detachably disposed. Thus, the second gasket 322 can be replaced as needed.

[0063] Specifically, at least one second shim 322 is located between the second mounting plate 321 and the positioning plate 21 along the second direction. The thickness of the second shim 322 affects the distance between the first positioning pin 31 and the second positioning pin 32 along the second direction. The distance between the first positioning pin 31 and the second positioning pin 32 can be adjusted by replacing the second shim 322 with shims of different thicknesses, making it suitable for brake caliper products of different sizes.

[0064] Specifically, at least one second shim 322 is located between the second mounting plate 321 and the positioning plate 21 along the first direction. The thickness of the second shim 322 affects the position of the second positioning pin 32 along the first direction. The position of the second positioning pin 32 along the first direction can be adjusted by replacing the second shim 322 with shims of different thicknesses, making it suitable for brake caliper products with different structures.

[0065] In practical applications, either the adjustable setting of the first positioning pin 31 or the adjustable setting of the second positioning pin 32 can be used, or both can be used simultaneously.

[0066] In one embodiment, the clamping device 20 includes a clamping unit 40, which is disposed at the middle position of the positioning plate 21, corresponding to the middle position of the brake caliper. The first positioning pin 31 and the second positioning pin 32 are respectively located on both sides of the positioning surface 201, corresponding to the two sides of the brake caliper. Thus, the positioning unit 30 and the clamping unit 40 cooperate to achieve a more comprehensive and balanced fixation of the brake caliper.

[0067] The clamping unit 40 includes a third mounting plate 41 fixed to the positioning plate 21, a drive unit 42 disposed on the third mounting plate 41, and a rotating arm 43 connected to the drive unit 42. The third mounting plate 41 is located above the positioning surface 201 along a first direction, and the drive unit 42 may be a cylinder.

[0068] The driving unit 42 drives the rotating arm 43 to rotate. When the rotating arm 43 rotates downward to face the positioning surface 201, the clamping unit 40 is in a clamping state. When the rotating arm 43 rotates upward to be offset from the positioning surface 201, the clamping unit 40 is in a yielding state.

[0069] The clamping unit 40 includes a clamping head 44 for clamping the brake caliper and a connector 45 for mounting the clamping head 44. The clamping head 44 is rotatably disposed relative to the connector 45, which can effectively adjust the clamping gap between the clamping head 44 and the brake caliper, improve the clamping holding force of the clamp, and minimize damage to the surface of the clamping contact surface of the brake caliper.

[0070] Specifically, one end of the connector 45 is connected to the rotating arm 43, and the other end is connected to the clamping head 44, so that when the rotating arm 43 rotates, it drives the clamping head 44 to rotate. When the clamping unit 40 is in the clamping state, the clamping head 44 is used to press against the brake caliper toward the positioning surface 201. When the clamping unit 40 is in the avoidance state, the clamping head 44 rotates to be offset from the positioning surface 201 to provide sufficient installation space for the brake caliper.

[0071] The clamping head 44 has a clamping plane 441 and a spherical surface 442. The spherical surface 442 is mounted on the connector 45. The connector 45 has a recessed space 451 for receiving the clamping head 44. The recessed space 451 has a spherical concave surface. The spherical concave surface and the spherical surface 442 are rotatably engaged, so that the clamping head 44 can be rotatably positioned.

[0072] The fixture 100 includes a floating support unit 50, which includes a floating support member 51 for supporting the brake caliper. This floating support unit can correct and reduce the positional displacement of the brake caliper that may be caused by excessive cutting force during the machining process, thus avoiding the risk of poor machining dimensions or tool damage. The floating support unit 50 is located below the positioning plate 21 and is used to support the bottom area of ​​the brake caliper.

[0073] The fixture 100 includes a converter 60 for connecting the brake caliper machining fixture 100 to a machining center. The converter 60 includes a converter plate 61 and a coupling member 62. The mounting frame 10 is connected to the converter plate 61. The coupling member 62 is used to connect the converter plate 61 and an external machining center, so that the fixture 100 can be adapted to different machining centers.

[0074] Specifically, combined Figure 11As shown, the adapter plate 61 and coupling member 62 are used together. When connected to the tray of one type of machining center, the fixture 100 can be directly connected to the adapter plate 61 for use. By removing the adapter plate 61 and coupling member 62, the fixture 100 can also be directly connected to the tray of another type of machining center for use. In this way, the fixture 100 can be adapted to different models of machining centers, making it highly versatile, reducing the design and manufacturing costs of the fixture 100, and facilitating fixture management.

[0075] This utility model also relates to a clamping assembly, including a brake caliper processing clamp 100 and a brake caliper as described in any of the technical solutions provided above, wherein the brake caliper is fixed to the brake caliper processing clamp.

[0076] The advantages of this utility model are as follows: the positioning surface 201 is used to cooperate with the flange surface of the brake caliper. The positioning surface 201 has an inclined angle, and a first acute angle α is formed between the positioning surface 201 and the operating surface, which is suitable for processing brake calipers with a flange having one torsion angle; the positioning surface 201 and the operating surface also form a second acute angle, which is suitable for processing brake calipers with a flange having two torsion angles; the first positioning pin 31 and the second positioning pin 32 have different sizes and structures, which has a foolproof function and prevents the left and right brake calipers from being installed incorrectly; the position and spacing of the first positioning pin 31 and the second positioning pin 32 can be adjusted to adapt to brake calipers of different sizes or structures; the clamping head 44 of the clamping unit can be deflected to adjust the clamping gap between the clamping head 44 and the brake caliper and improve the clamping and holding force of the fixture; the adapter 60 allows the fixture 100 to be connected to and adapted to different machining centers.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
