[0055] This embodiment provides a tool for a wheel cylinder support of an automobile, and the tool for the wheel cylinder support 10 of the automobile is used to clamp or fix the wheel cylinder support 10 of the automobile. The tool for the wheel cylinder support 10 of the automobile includes a base 20, a fixing device 30, two top support rods 40 and a power mechanism 50.

[0056] The fixing device 30 is used to fix the vehicle wheel cylinder bracket 10 on the base 20 .

[0057] The top support rod 40 is arranged on the base 20 so as to be movable along its axial direction, and the top support rod 40 corresponds to and is coaxial with the mounting hole 11. The power mechanism 50 can drive the top support rod 40 to abut against the back side of the corresponding mounting hole 11 on the automobile wheel cylinder bracket 10. Specifically, the power mechanism 50 can be a hydraulic cylinder 334 or an air cylinder, and the push rod of the hydraulic cylinder 334 or the air cylinder is connected to the top support rod 40 coaxially with the center line; or the combination of the power mechanism 50 and the top support rod 40 uses a hydraulic cylinder 334 or an air cylinder or an electric push rod, and the telescopic end of the hydraulic cylinder 334 or the air cylinder or the electric push rod is used to abut against the back side of the corresponding mounting hole 11 on the automobile wheel cylinder bracket 10. Specifically, the mounting hole 11 is provided on the side of the automobile wheel cylinder bracket 10 away from the top support rod 40.

[0058] In this embodiment, after the automobile wheel cylinder bracket 10 is fixed on the base 20, the top support rod 40 is driven by the power mechanism 50 to lean against the automobile wheel cylinder bracket 10, and then processing is performed at the mounting hole 11. The external force applied to the mounting hole 11 is transmitted to the automobile wheel cylinder bracket 10 and offset by the top support rod 40, thereby avoiding deformation of the automobile wheel cylinder bracket 10, so that the verticality of the axis of the mounting hole 11 and the mounting surface can be guaranteed, thereby improving the yield rate and reducing costs.

[0059] In one embodiment, the base 20 includes a support platform 21 and a base, and the support platform 21 is installed on the base.

[0060] Support blocks 22 extending axially along the mounting hole 11 are respectively provided on both sides of the support platform 21. The two support blocks 22 are used to support the second U-shaped frame of the automobile wheel cylinder bracket. Specifically, the two support blocks 22 correspond one-to-one with the two second limiting grooves 141 on the two arms of the second U-shaped frame 14, and slide together, so as to be infected to form a support. The fixing device 30 can fix the automobile wheel cylinder bracket 10 on the support platform 21. The top support rod 40 is used to abut against the second U-shaped frame 14 of the automobile wheel cylinder bracket 10. Specifically, the two top support rods 40 are respectively abutted against the lower ends of the two arms of the second U-shaped frame 14.

[0061] In this embodiment, the wheel cylinder bracket 10 is slid from one end of the support platform 21 along the support block 22, and then the top support rod 40 is against the second U-shaped frame 14, and the external force applied at the mounting hole 11 is processed in the direction along the connecting beam 12 and from the first U-shaped frame 13 to the second U-shaped frame 14. The support block 22 limits the first U-shaped frame 13 and the second U-shaped frame 14 in the vertical direction, thereby cooperating with the top support rod 40 to limit the entire wheel cylinder bracket 10.

[0062] In one embodiment, the two sides of the front end of the upper end surface of the support platform 21 are respectively used to support the first limiting steps on the double arms of the first U-shaped frame 13, and the two sides of the rear end surface of the upper end surface of the support platform 21 are respectively used to support the second limiting steps 142 on the double arms of the second U-shaped frame 14. Specifically, the end of the upper end surface of the support platform 21 away from the two top support rods 40 is the front end, and the end of the upper end surface of the support platform 21 close to the two top support rods 40 is the rear end. The first U-shaped frame 13 and the second U-shaped frame 14 can slide on the support platform 21 through the first limiting step 131 and the second limiting step 142.

[0063] In this embodiment, when the wheel cylinder bracket 10 is placed on the support platform 21, the size of the support block 22 on the support platform 21 can be appropriately reduced to facilitate the second limiting groove 141 to cooperate with the support block 22 on the same side. When the wheel cylinder bracket 10 is installed in place, the first limiting step 131 and the second limiting step 142 fit with the upper end plane of the support platform 21, so that the entire wheel cylinder bracket 10 is positioned on the support platform 21 under gravity.

[0064] In one embodiment, two limit blocks 24 are further included. The support platform 21 is provided with mounting grooves 23 on both sides. The limit blocks 24 are installed in the corresponding mounting grooves 23 by bolts. Specifically, by unscrewing the bolts, the limit blocks 24 can also be removed from the mounting grooves 23. The end of the limit block 24 away from the bottom of the mounting groove 23 is connected to a stop block 27, which is used to abut against a side of the first U-shaped frame 13 facing the second U-shaped frame 14.

[0065] In this embodiment, after the automobile wheel cylinder bracket 10 is slid from the support block 22 and placed on the support platform 21, the limit block 24 is pushed into the installation groove 23 on the same side, and the limit block 24 is fixed in the installation groove by bolts. In addition, a protrusion 26 is provided in the installation groove, and a through hole matching the protrusion 26 is provided on the limit block 24. The protrusion 26 can limit the limit block 24 so that it cannot rotate. At this time, one end of the stopper 27 connected to the limit block 24 just abuts against the first U-shaped frame 13, forming support for the first U-shaped frame 13.

[0066] In one embodiment, the support platform 21 includes two parallel mounting blocks 28, a connecting block 29 is arranged between the two mounting blocks 28, and the two ends of the connecting block 29 are connected to the two mounting blocks 28. The mounting blocks 28 and the connecting blocks 29 are both mounted on the base. The upper end surface of the mounting block 28 is used to carry the first limiting step 131 and the second limiting step 142. The two mounting blocks 28 are connected to the support block 22 on the sides facing away from each other; the two mounting blocks 28 are provided with a first fixing hole 281 on the sides facing away from each other.

[0067] The fixing device 30 includes a fixing block 31 and a fixing mechanism 32 .

[0068] There are two fixing blocks 31, and the two fixing blocks 31 are respectively slidably matched in the corresponding first fixing holes 281. The fixing mechanism 32 can be used to drive the fixing blocks 31 to move and abut against the two arms of the first U-shaped frame 13.

[0069] In this embodiment, driven by the fixing mechanism 32, the two fixing blocks 31 can be moved out of the first fixing hole 281 and abut against the two arms of the first U-shaped frame 13. On the one hand, the automobile wheel cylinder bracket 10 can be fixed, and on the other hand, the lateral size of the support block 22 can be slightly reduced, so that it is more convenient to place the automobile wheel cylinder bracket 10 on the support platform 21.

[0070] In one embodiment, a second fixing hole 282 is formed on the opposite sides of the two mounting blocks 28, and the first fixing hole 281 and the second fixing hole 282 on the same mounting block 28 are coaxial and connected through a transition hole 283;

[0071] The fixing mechanism 32 includes two driving rods 321 , two retaining rings 322 and a driving mechanism 33 .

[0072] One end of the driving rod 321 passes through the transition hole 283 on the same side and is connected to the corresponding fixing block 31. A retaining ring 322 is sleeved on the ends of the two driving rods 321 away from the fixing block 31. The spring 323 is sleeved on the corresponding driving rod 321, one end of the spring 323 abuts against the bottom of the second fixing hole 282, and the other end of the spring 323 abuts against the retaining ring 322 on the same side. The driving mechanism 33 abuts against the driving rods 321 on both sides and can drive the driving rods 321 to slide in the transition hole 283 to drive the two fixing blocks 31 to extend and abut against the two arms of the first U-shaped frame 13 at the same time.

[0073] In this embodiment, under the drive of the driving mechanism 33, the two driving rods 321 can slide in the transition hole 283 to drive the fixing block 31 to abut against the two arms of the first U-shaped frame 13 on both sides, thereby fixing the vehicle wheel cylinder bracket 10.

[0074] In one embodiment, a first installation cavity 291 extending transversely therethrough and a second installation cavity 292 extending vertically therethrough are defined in the connection block 29 , and the second installation cavity 292 is in communication with the first installation cavity 291 .

[0075] The driving mechanism 33 includes two driving blocks 331 , two matching blocks 332 , a power block 333 and a hydraulic cylinder.

[0076] The two driving blocks 331 are slidably mounted at two ends of the first mounting cavity 291 , and the two driving blocks 331 are respectively abutted against the corresponding driving rods 321 .

[0077] The two matching blocks 332 are parallel to each other, and the two matching blocks 332 are respectively connected to one end of the corresponding driving block 331 away from the driving rod 321.

The push rod 334 of the hydraulic cylinder is connected to the upper power block 333, and the push rod 334 of the hydraulic cylinder is arranged in the second installation cavity 292. The opposite side of the two matching blocks 332 is provided with an inclined driving groove 335. Specifically, the projections of the two driving grooves 335 on one surface of the power block 333 intersect with each other. The driving groove 335 on the same side of the power block 333 is provided with a feed block 336 that slidably cooperates with it. The feed block 336 is also arranged obliquely. When the power block 333 moves upward, the two matching blocks 332 are driven by the feed block 336 to move away from the drive rod 321 that is against the drive block 331 on the same side, so that the drive rod 321 is retreated under the action of the spring 323 and is close to the drive block 331. When the power block (333) moves upward, the two drive blocks (331) move together at the same time through the matching block (332) and the feed block (336); when the power block (333) moves downward, the two drive blocks (331) move away from each other at the same time through the matching block (332) and the feed block (336), thereby pushing the two drive rods 321 and the two fixing blocks 31 away from each other at the same time, thereby fixing the vehicle wheel cylinder bracket 10.
