[0029] The following is combined with Figure 1-4 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0030] The present application discloses an automatic clamping tool for drilling a brake caliper:

[0031] Reference Figure 1-Figure 3 An automatic clamping tool for drilling a brake caliper includes a machine platform 1, on which a clamping mechanism 2 is fixed, the clamping mechanism 2 includes a fixed structure 21, a first motor 22 and a translation structure 23; the fixed structure 21 includes a clamping block 211 and an automatic locking structure 214, the clamping block 211 slides on the machine platform 1 through the translation structure 23, and the top of the clamping block 211 is arc-shaped. The operator first clamps the brake caliper 4 on the clamping block 211 through the buckle position 41, and the automatic locking structure 214 is started to automatically clamp the brake caliper 4 on the clamping block 211, thereby realizing automatic clamping, thereby reducing manpower consumption; then the processing matching hole 43 on the processing position 5 is processed, and after the processing is completed, the first motor 22 drives the fixed structure 21 to rotate, thereby driving the brake caliper 4 to rotate, and then the processing matching hole 43 is replaced with the processed matching hole 43. After the rotation is completed, there is still a deviation between the processing matching hole 43 and the processing position 5. At this time, the translation structure 23 sends the processing matching hole 43 to the processing position 5, completing the ability to automatically switch the processing matching hole 43.

[0032] Reference Figure 2 , baffles 212 are fixed at both ends of the clamping block 211 along the length direction of the machine 1. When the brake caliper 4 is clamped on the clamping block 211, the baffles 212 abut against the side of the brake caliper 4. The width of the clamping block 211 perpendicular to the length direction of the machine 1 is the same as the width D of the buckle position 41. The width of the clamping block 211 perpendicular to the length direction of the machine 1 is set to be the same as the width D of the buckle position 41, thereby ensuring that the brake caliper 4 remains stable during the clamping process and is in close contact with the clamping block 211 to provide a better clamping effect. The existence of the baffle 212 provides a small platform for the brake caliper 4, so that the brake caliper 4 can be stably placed and clamped on the clamping block 211 after the operator lets go.

[0033] Reference Figure 2-Figure 4 The automatic locking structure 214 includes a cylinder 215 and a rotating fixing member 216. The cylinder 215 is located inside the clamping block 211, and the telescopic rod of the cylinder 215 is arranged toward the insertion hole 42. The clamping block 211 is provided with an annular groove 213. When the brake caliper 4 is clamped on the clamping block 211 through the buckle position 41, the telescopic rod of the cylinder 215 passes through the annular groove 213 and is inserted into the insertion hole 42.

[0034] The rotating fixing member 216 is respectively arranged at both ends of the clamping block 211. The rotating fixing member 216 includes a second motor 217 and a fastener 218. The second motor 217 is fixed on the machine 1, and the second motor 217 is arranged perpendicular to the length direction of the machine 1. The fastener 218 rotates on the second motor 217. When the second motor 217 drives the fastener 218 to rotate, the fastener 218 rotates toward the clamping block 211 until it is clamped on the brake caliper 4. The cylinder 215 is pushed out and inserted into the insertion hole 42, thereby limiting the movement of the fixing member in the direction perpendicular to the length direction of the machine 1; the fastener 218 is buckled on the brake caliper 4, and cooperates with the baffle 212 to limit the movement of the fixing member in the length direction of the machine 1.

[0035] Reference Figure 4 The automatic locking structure 214 also includes a trigger structure 3, which includes a first travel switch 31 and a second travel switch 32. The first travel switch 31 is fixed on the top surface of the baffle 212, and the second travel switch 32 is located on the rotation path of the fastener 218. When the brake caliper 4 is clamped on the clamping block 211 and one side is abutted on the top surface of the baffle 212, the first travel switch 31 is triggered, thereby opening the rotating fixing member to work, allowing the fastener 218 to rotate and clamp on the brake caliper 4. Subsequently, the second travel switch 32 fixed on the fastener 218 is triggered to push out the telescopic rod of the cylinder 215, thereby completing the automatic locking.

[0036] Reference Figure 2-Figure 3 The first motor 22 is fixed to the outside of the block 211, and the first motor 22 also includes an output end 221, which is arranged toward the block 211 and inserted into the inside of the block 211, and the cylinder 215 is fixed to the output end 221. In the process of rotating the brake caliper 4, the first motor 22 rotates the cylinder 215 fixed to the output end 221, thereby rotating the telescopic rod of the cylinder 215, thereby driving the brake caliper 4 provided on the telescopic rod to rotate.

[0037] Reference Figure 2 The translation structure 23 includes a lead screw 231 and a power source 232. The lead screw 231 is fixed on the machine platform 1 in parallel with the length direction of the machine platform 1. The lead screw 231 is located below the clamping block 211, and the clamping block 211 slides on the lead screw 231. After the brake caliper 4 rotates, the matching hole 43 to be processed is not on the processing position 5. The power source 232 drives the lead screw 231 to rotate, thereby driving the clamping block 211 to move back and forth on the lead screw 231 along the length direction of the lead screw 231, and delivering the matching hole 43 to be processed to the processing position 5.

[0038] When the matching hole 43 on one side is processed, the processing tool is withdrawn, the fastener 218 rotates to release the lock on the brake caliper 4, and the first motor 22 drives the cylinder 215 to drive the brake caliper 4 to rotate until it fits with the baffle 212 on the other side. The first stroke switch 31 on the baffle 212 on the other side is triggered, and the translation structure 23 is started. After a designed distance is translated along the length direction of the machine 1, the fastener 218 on the other side rotates until it abuts against the brake caliper 4, and then the processed matching hole 43 is processed.

[0039] Reference Figure 2-Figure 3 The top of the block 211 and the contact surface of the block 211 are coated with polytetrafluoroethylene, which forms a low-friction coating after air drying. The friction coefficient of polytetrafluoroethylene is extremely low, thereby reducing the friction between the block 211 and the brake caliper 4, reducing the wear on the brake caliper 4 and reducing the situation where the brake caliper 4 is stuck on the block 211 when rotating.

[0040] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
