Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and in particular to an auxiliary fixing device and a clamp for a fixture. Background Technology

[0002] Brake calipers are one of the core components of the braking system and are widely used in vehicles. They generate braking force through the interaction between the caliper and the brake disc. Brake calipers are typically fixed to the vehicle's frame, while the brake disc is fixed to the wheel. To ensure the vehicle remains stationary when parked, parking calipers are additionally installed on the brake disc. Parking calipers provide a continuous and stable clamping force on the brake disc when the vehicle is parked, ensuring its stability.

[0003] The brake caliper on a car includes a caliper bracket, which is usually irregularly shaped. During machining, the caliper bracket needs to be fixed to a fixture. For example... Figure 1 As shown, Figure 1 This is a three-dimensional structural diagram of an auxiliary fixing device for a clamp in the prior art. The auxiliary fixing device is used to fix a caliper bracket 101. The caliper bracket 101 includes a crossbar 1011 and two tails 1012, one end of each tail 1012 being connected to both ends of the crossbar 1011. The clamp includes a support base 81 and a clamping mechanism. Two clamping mechanisms are provided, respectively arranged opposite to both ends of the support base 81. The clamping mechanism includes a pressure rod 82 and an elastic member 83. The pressure rod 82 is arranged vertically, and its lower end is connected to the elastic member 83. Through the elastic member 83, the pressure rod 82 can move between being away from and close to the support base 81. When the pressure bar 82 is away from the support base 81, the caliper bracket 101 can be placed. When the pressure bar 82 is close to the support base 81, it abuts against the U-reference surface 10121 located at the lower end of the tail 1012 of the caliper bracket 101, pressing the caliper bracket 101 between the support base 81 and the pressure bar 82, thereby fixing the caliper bracket 101 to the clamp. However, when placing the caliper bracket 101, it is necessary to manually pry the pressure bar 82 outward using the caliper bracket 101 so that the caliper bracket 101 can be placed on the support base 81 and fixed by the pressure bar 82. Similarly, when removing the caliper bracket 101, the pressure bar 82 also needs to be pried outward. Therefore, the process of installing and removing the caliper bracket is rather cumbersome.

[0010] The drive unit is connected to the second limiting member and is used to drive the second limiting member to reciprocate in the second direction; when the second limiting member moves to a preset position, the clamping member and the first limiting member can clamp the caliper bracket in the second direction.

[0011] According to another specific embodiment of the present invention, there are two clamping members, namely a first clamping member and a second clamping member. The first clamping member and the second clamping member are respectively disposed on both sides of the support unit along the first direction. The first clamping member and a limiting part are disposed opposite to each other along the second direction, and the second clamping member and another limiting part are disposed opposite to each other along the second direction.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The auxiliary fixing device for the clamp provided by this utility model can automatically fix the caliper bracket. When the caliper bracket is placed on the auxiliary fixing device, the two tail portions of the caliper bracket are respectively opposite to the two limiting portions, which can support and block the two tail portions, thereby limiting the displacement of the caliper bracket in the first direction; the crossbar of the caliper bracket rests on the support unit. The drive unit is activated, which drives the second limiting member to move towards the direction of the first limiting member. When the second limiting member moves to the preset position, the clamping member abuts against one side of the caliper bracket, and the other side of the caliper bracket abuts against the limiting portion. The limiting portion and the clamping member generate a clamping force on the caliper bracket, thereby limiting the displacement of the caliper bracket in the second direction, and thus fixing the caliper bracket to the clamp. In addition, the support unit supports the caliper bracket from below, which can prevent the caliper bracket from tipping over. According to the auxiliary fixing device and clamp provided by this utility model, the caliper bracket can be fixed simply by placing it on the support unit, without having to pry open the pressure bar, which is simple to operate and improves production efficiency.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] like Figure 2 and Figure 3 As shown, Figure 2 This is a three-dimensional structural diagram of an auxiliary fixing device for a clamp containing a caliper bracket 101, according to an embodiment of the present invention. Figure 3 This is a three-dimensional structural diagram of an auxiliary fixing device for a clamp without a caliper bracket 101, according to an embodiment of the present invention. The auxiliary fixing device assists in fixing the caliper bracket 101 to the clamp. The caliper bracket 101 includes a crossbar 1011 and two tails 1012, the first ends of which are respectively connected to the two ends of the crossbar 1011.

[0041] In this embodiment, the auxiliary fixing device of the clamp includes a base 1, a first limiting member 2, a second limiting member 3, and a driving unit 4.

[0042] The first limiting member 2 is disposed at one end of the base 1, and the first limiting member 2 is provided with two points along the first direction (e.g., Figure 2 The limiting parts 21 (as shown in the x-direction) are spaced apart. The two limiting parts 21 are used to support and block the second ends of the two tail parts 1012 and to limit the displacement of the caliper bracket 101 along the first direction.

[0043] The second limiting member 3 is slidably connected to the base 1, and the second limiting member 3 can move relative to the base 1 along a second direction (e.g., Figure 2 Sliding in the y-direction, the second direction is perpendicular to the first direction. The second limiting member 3 includes a support unit 31 and a clamping member 32. The support unit 31 is used to support the caliper bracket 101 from below. The clamping member 32 is arranged opposite to the first limiting member 2 in the second direction.

[0044] The drive unit 4 is connected to the second limiting member 3 and is used to drive the second limiting member 3 to reciprocate in the second direction; when the second limiting member 3 moves to the preset position, the clamping member 32 and the first limiting member 2 can clamp the caliper bracket 101 in the second direction.

[0045] For example, refer to Figure 3 In this embodiment, the limiting part 21 includes a first limiting surface 211, a second limiting surface 212, and a third limiting surface 213. The first limiting surface 211 and the second limiting surface 212 are located at the upper part of the limiting part 21, and the third limiting surface 213 is located at the lower part of the limiting part 21 and faces the second limiting member 3. The first limiting surface 211 is used to support the caliper bracket 101 from below the second end of the tail 1012; the second limiting surface 212 is a vertical surface and extends along the second direction, and is used to abut against the inner surface of the tail 1012 so as to limit the displacement of the caliper bracket 101 along the first direction; the third limiting surface 213 is a vertical surface and faces the second limiting member 3, and is used to block the second end of the tail 1012 and can generate a clamping force on the tail 1012 with the clamping member 32.

[0046] When it is necessary to fix the caliper bracket 101, the caliper bracket 101 is first placed on the auxiliary fixing device. The two tails 1012 of the caliper bracket 101 are respectively opposite to the two limiting parts 21, and the two tails 1012 are respectively placed on the two first limiting surfaces 211. The crossbar 1011 of the caliper bracket 101 is placed on the support unit 31, thereby supporting the two tails 1012 of the caliper bracket 101 through the two limiting parts 21 and restricting the displacement of the caliper bracket 101 in the first direction. The support unit 31 provides support force to the crossbar 1011 of the caliper bracket 101. Then, the drive unit 4 is activated, which drives the second limiting member 3 to move towards the first limiting member 2, causing the clamping member 32 to abut against the U-reference surface 10121 of the caliper bracket 101, and causing the other side of the caliper bracket 101 to abut against the third limiting surface 213 of the limiting part 21. By applying clamping force to the U-reference surface 10121 through the clamping member 32 and the third limiting surface 213, the displacement of the caliper bracket 101 in the second direction can be restricted, thereby fixing the caliper bracket 101 to the fixture. Additionally, the support unit 31 supports the caliper bracket 101 from below, preventing it from tipping over. According to the auxiliary fixing device for the fixture provided by this invention, the caliper bracket 101 can be fixed simply by placing it onto the support unit 31, without needing to pry open the clamping rod, simplifying operation and improving production efficiency.

[0047] It is worth noting that when placing the caliper bracket 101 on the auxiliary fixing device, it can be done manually or by a robot or robotic gripper.

[0048] The drive unit 4 and the second limiting member 3 are both mounted on the base 1. The second limiting member 3 and the first limiting member 2 are spaced apart along the second direction. The output end of the drive unit 4 is connected to the second limiting member 3. The drive unit 4 can drive the second limiting member 3 to reciprocate between a preset position and a placement position along the second direction. When the second limiting member 3 is in the placement position, it is away from the first limiting member 2. At this time, the caliper bracket 101 can be inserted into the space between the first limiting member 2 and the second limiting member 3. The caliper bracket 101 is placed on the support unit 31. The two tails 1012 of the caliper bracket 101 are located on the two first limiting surfaces 211, and the crossbar 1011 is located on the support unit 31, thereby supporting the caliper bracket 101 from below. When the second limiting member 3 is in the preset position, the second limiting member 3 approaches the first limiting member 2. At this time, the clamping member 32 in the second limiting member 3 abuts against the U reference surface 10121 of the caliper bracket 101. The clamping member 32 provides a clamping force in the second direction to the U reference surface 10121, so that the caliper bracket 101 is clamped between the third limiting surface 213 and the clamping member 32, thereby pressing and fixing the caliper bracket 101 in the second direction.

[0049] Furthermore, there are two clamping members 32, namely a first clamping member 321 and a second clamping member 322. The first clamping member 321 and the second clamping member 322 are respectively disposed on both sides of the support unit 31 along the first direction. The first clamping member 321 is disposed opposite to a limiting part 21 along the second direction, and the second clamping member 322 is disposed opposite to another limiting part 21 along the second direction.

[0050] Specifically, the first clamping member 321 and the second clamping member 322 are symmetrically disposed on the two outer side walls of the support unit 31, and correspond to the two limiting portions 21 of the first limiting member 2, respectively, for abutting against the two tail portions 1012 of the caliper bracket 101. The first clamping member 321 provides a force in the second direction to the U-reference surface 10121 of one tail portion 1012. Through the cooperation of the first clamping member 321 and the third limiting surface 213 of the limiting portion 21, one tail portion 1012 of the caliper bracket 101 can be fixed in the second direction. The second clamping member 322 provides a force in the second direction to the U-reference surface 10121 of the other tail portion 1012. Through the cooperation of the second clamping member 322 and the third limiting surface 213 of the other limiting portion 21, the other tail portion 1012 of the caliper bracket 101 can be fixed in the second direction. Therefore, by means of the first clamping member 321, the second clamping member 322 and the two limiting parts 21, the displacement of the caliper bracket 101 in the second direction can be restricted.

[0051] Further, refer to Figure 3 and Figure 6The first clamping member 321 includes a first connecting part 3211 and a first abutting part 3212. The first connecting part 3211 is detachably connected to the outer side wall of one side of the support unit 31, and the first abutting part 3212 is connected to one end of the first connecting part 3211 for abutting against the caliper bracket 101.

[0052] The second clamping member 322 includes a second connecting part 3221 and a second abutting part 3222. The second connecting part 3221 is detachably connected to the outer side wall of the other side of the support unit 31. The second abutting part 3222 is connected to one end of the second connecting part 3221 and is used to abut against the caliper bracket 101.

[0053] Specifically, in this embodiment, the first connecting portion 3211 and the second connecting portion 3221 are detachably fixed to the outer side walls of the support unit 31 on both sides by screws. The first connecting portion 3211 and the second connecting portion 3221 are cuboid in shape and extend along the second direction on the outer side walls of the support unit 31.

[0054] The first abutting portion 3212 is disposed at the end of the first connecting portion 3211 near the first limiting member 2, and the second abutting portion 3222 is disposed at the end of the second connecting portion 3221 near the first limiting member 2. It is worth noting that the first connecting portion 3211 and the first abutting portion 3212, the second connecting portion 3221 and the second abutting portion 3222 can be integrally formed or separately formed, and this utility model does not impose any limitation on this.

[0055] Optionally, in one embodiment, the surfaces of the first abutting portion 3212 and the second abutting portion 3222 that abut against the U-reference surface 10121 are planar. In another embodiment, the end of the first abutting portion 3212 away from the first connecting portion 3211 and the end of the second abutting portion 3222 away from the second connecting portion 3221 are respectively provided with claw portions 323, which protrude toward the side of the first limiting member 2 to adapt to the shape of the U-reference surface 10121 of the caliper bracket 101, so as to be suitable for the U-reference surface 10121 with a stepped portion.

[0056] Furthermore, the base 1 is provided with a slide groove 11 extending in the second direction, and a slider 12 is provided below the second limiting member 3. The slider 12 is located in the slide groove 11 and can slide along the slide groove 11. The driving end of the driving unit 4 is connected to the slider 12, and the support unit 31 is located on the slider 12.

[0057] Using this technical solution, the slider 12 is driven by the drive unit 4 to move along the extension direction of the slide groove 11, so as to drive the support unit 31 to move back and forth in the second direction.

[0058] Further, refer to Figure 2 , 4and Figure 5 In this embodiment, a height adjustment block 5 is also included, which is disposed between the slider 12 and the support unit 31.

[0059] By setting the height adjustment block 5, the height of the top of the support unit 31 can be adjusted, thereby adapting to caliper brackets 101 of different specifications.

[0060] Furthermore, the support unit 31 includes a bottom 313, which has a through third threaded hole 3131. In this embodiment, the height adjustment block 5 includes a stud 51, a nut 52, and a screw 53.

[0061] The stud 51 is disposed on the slider 12. The stud 51 has external threads, and the upper part of the stud 51 is provided with a first threaded hole 511.

[0062] The inner surface of the nut 52 is provided with an internal thread. The nut 52 covers the outside of the stud 51 and is threadedly connected to the external thread of the stud 51. The bottom 313 of the support unit 31 is located above the nut 52. The upper part of the nut 52 is provided with a through second threaded hole 521. The first threaded hole 511, the second threaded hole 521 and the third threaded hole 3131 are opposite to each other.

[0063] The screw 53 is inserted through the third threaded hole 3131 and the second threaded hole 521 and then into the first threaded hole 511, and is threadedly connected to the first threaded hole 511, the second threaded hole 521 and the third threaded hole 3131.

[0064] Specifically, in this embodiment, the slider 12 and the stud 51 are integrally formed, so that the stud 51 is fixedly disposed above the slider 12, which can improve the adjustment accuracy of the height adjustment block 5. In other embodiments, the slider 12 and the stud 51 can be formed separately.

[0065] In this embodiment, the height of the nut 52 is adjusted by rotating the nut 52, thereby adjusting the height of the support unit 31.

[0066] The stud 51 has a first threaded hole 511 in its middle, the nut 52 has a through second threaded hole 521 in its middle, and the support unit 31 has a through third threaded hole 3131 in its bottom 313. The central axes of the first threaded hole 511, the second threaded hole 521, and the third threaded hole 3131 are on a straight line, and their inner diameters are the same. The screw 53 has an external thread, and the screw 53 is threadedly connected to the third threaded hole 3131, the second threaded hole 521, and the first threaded hole 511. By inserting the screw 53 from above the bottom 313 of the support unit 31 and passing it sequentially through the third threaded hole 3131 and the second threaded hole 521, the lower end of the screw 53 is inserted into the first threaded hole 511, thereby fixing the support unit 31 to the height adjustment block 5.

[0067] Optionally, in this embodiment, six fourth threaded holes 512 are evenly provided along the circumference of the stud 51, and two fifth threaded holes 522 are symmetrically provided in the radial direction of the nut 52 relative to the second threaded hole 521. The radial distance of the fifth threaded hole 522 relative to the central axis of the nut 52 is the same as the radial distance of the fourth threaded hole 512 relative to the central axis of the stud 51. When the nut 52 is rotated to different positions, the two fifth threaded holes 522 correspond to the two corresponding fourth threaded holes 512, and screws are screwed into the fifth threaded holes 522 and the fourth threaded holes 512, thereby fixing the nut 52 relative to the stud 51 and preventing the nut 52 from rotating during processing and affecting the height of the support unit 31.

[0068] Optional, see reference Figures 4 to 6 In this embodiment, six pin holes 523 are evenly provided along the circumference of the nut 52. Two pins 315 are provided below the bottom 313 of the support unit 31. These two pins 315 are located in the radial direction of the third threaded hole 3131 and are symmetrically arranged relative to the third threaded hole 3131 in the second direction. The pins 315 are used to insert into the pin holes 523. In use, the two pins 315 are respectively inserted into the corresponding pin holes 523 to fix the support unit 31 on the nut 52 and prevent the support unit 31 from shifting.

[0069] The support unit 31 is fixed relative to the nut 52 by the pin 315, and the nut 52 is fixed relative to the stud 51 by the screw, which can make the height and position of the support unit 31 stable, thereby improving the machining accuracy of subsequent processing.

[0070] Furthermore, such as Figure 6 As shown, in this embodiment, the support unit 31 further includes a first support portion 311 and a second support portion 312. The first support portion 311 and the second support portion 312 are respectively disposed at intervals along a first direction at both ends of the bottom 313. The first support portion 311 and the second support portion 312 are used to provide support for the caliper bracket 101.

[0071] In this technical solution, the first support part 311 and the second support part 312 are respectively located above the two ends of the bottom 313. The support unit 31 is in the shape of an upward-opening U-shape. The middle part of the support unit 31 forms a relief part 314 extending in the second direction to avoid the protruding part of the crossbar 1011 of the caliper bracket 101.

[0072] Because the lower surface of the crossbar 1011 of the caliper bracket 101 has a slightly downward-protruding sealing line, therefore, reference Figure 3 and Figure 4The upper end of the first support 311 and the middle part of the upper end of the second support 312 are respectively provided with a first recess 3111 and a second recess 3121. When the second limiting member 3 is in the preset position, the sealing line on the caliper bracket 101 falls into the first recess 3111 and the second recess 3121, so that in the subsequent processing of the caliper bracket 101, by avoiding the sealing line of the caliper bracket 101, the lower surface of the crossbar 1011 of the caliper bracket 101 can contact the upper end of the first support 311 and the second support 312, thereby preventing the caliper bracket 101 from shaking during the processing of the caliper bracket 101 when the support part supports the caliper bracket 101.

[0073] Furthermore, the cross-sectional area of ​​the longitudinal section at the top of the first support portion 311 and the second support portion 312 gradually increases from top to bottom. The longitudinal section is a cut surface obtained by cutting the support portion perpendicularly along the first direction.

[0074] By adopting this technical solution, the contact area between the first support part 311 and the second support part 312 and the caliper bracket 101 can be reduced, thereby reducing the friction between the support unit 31 and the crossbar 1011 during the movement of the support unit 31.

[0075] Optionally, in this embodiment, the drive unit 4 is a cylinder.

[0076] According to the auxiliary fixing device of the clamp provided by this utility model, in use, the driving unit 4 drives the slider 12 to slide away from the first limiting member 2, so that the slider 12 slides to the placement position, and then the caliper bracket 101 is horizontally placed on the second limiting member 3. The two tails 1012 of the caliper bracket 101 are respectively located on the two first limiting surfaces 211 of the first limiting member 2, and the crossbar 1011 of the caliper bracket 101 rests on the first support part 311 and the second support part 312. Thus, the caliper bracket 101 is supported from below by the first limiting surface 211, the first support part 311, and the second support part 312, and the displacement of the caliper bracket 101 in the first direction is restricted by the second limiting surface 212. Subsequently, the drive unit 4 drives the slider 12 to retract to a preset position. At this position, the first clamping member 321 and the second clamping member 322 abut against the two U-reference surfaces 10121 below the caliper bracket 101, and the first clamping member 321 and the second clamping member 322 provide clamping force to the U-reference surface 10121 of the caliper bracket 101, pressing against the third limiting surface 213, thereby clamping the caliper bracket 101 between one third limiting surface 213 and the first clamping member 321 and between the other third limiting surface 213 and the second clamping member 322, thereby pressing and fixing the caliper bracket 101 in the second direction.

[0077] The auxiliary fixing device for the clamp provided by this utility model can automatically fix the caliper bracket by placing it on the support unit. The operation is simple, and since there is no need to pry open the pressure bar during the fixing process, it can be used in conjunction with a robot to improve production efficiency.

[0078] An embodiment of this utility model also provides a clamp, including an auxiliary fixing device for the clamp as described above.

Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
