The U-shaped member 13 is connected to the end of the connecting beam 11 away from the sleeve 12, and the two arms of the U-shaped member 13 and the sleeve 12 are located on the same side of the connecting beam 11, and a space for placing the brake pad is formed between the two arms of the U-shaped member 13 and the sleeve 12.

[0044] See also Figure 3 and 4 The present embodiment provides a vehicle brake cylinder housing tooling, including a base 20, a support seat 30, a bracket 40, a first hydraulic cylinder 50 and a pressing head 51.

[0045] The support seat 30 is arranged on the base 20, and the support seat 30 has a first positioning protrusion 31 for supporting the first positioning notch 111 of the automobile brake cylinder housing 10. The support seat 30 supports and positions the automobile brake cylinder housing 10 by means of the first positioning protrusion 31. In addition, other parts of the support seat 30 can also cooperate with the first positioning protrusion 31 to support and position the automobile brake cylinder housing 10. Specifically, the first positioning protrusion 31 can fit with the first positioning notch 111 of the connecting beam 11 to support and position the automobile brake cylinder housing 10. The bracket 40 is connected to the base 20, and the first hydraulic cylinder 50 is connected to the bracket 40, and the first hydraulic cylinder 50 is correspondingly arranged with the support seat 30. The pressing head 51 is connected to the output end of the first hydraulic cylinder 50, and the pressing head 51 is located above the first positioning protrusion 31 and directly opposite to the first positioning protrusion 31, and the pressing head 51 is used to press the logo on the automobile brake cylinder housing 10. Specifically, the pressing head 51 is made of hard alloy, and the contact position between the pressing head 51 and the automobile brake cylinder housing 10 is a reverse molded tooth.

[0046] In this embodiment, the automobile brake cylinder housing 10 is placed on the support seat 30, and the first positioning notch 111 of the automobile brake cylinder housing 10 is just placed on the first positioning protrusion 31, and the other positions of the automobile brake cylinder housing 10 are in contact with other positions of the support seat 30 and supported. The output end of the first hydraulic cylinder 50 drives the pressing head 51 to lean against the automobile brake cylinder housing 10 and press out a mark. Since the pressing head 51 and the first positioning protrusion 31 are facing each other, the automobile brake cylinder housing 10 is offset by external force, so it will not be deformed due to unilateral force, thereby improving the yield rate of the automobile brake cylinder housing 10.

[0047] In one embodiment, the support seat 30 further has a second positioning protrusion 32 and a third positioning protrusion 33 .

[0048] Both the second positioning protrusion 32 and the third positioning protrusion 33 can position and support the automobile brake cylinder housing 10. Specifically, the bottom of the U-shaped member 13 is provided with a second positioning notch 131 and a third positioning notch 132. The second positioning notch 131 and the third positioning notch 132 are respectively located below the arms of the U-shaped member 13. The second positioning protrusion 32 can abut against the second positioning notch 131 in the vertical direction, so that the second positioning protrusion 32 supports the automobile brake cylinder housing 10. The second positioning protrusion 32 can also abut against the second positioning notch 131 in one horizontal direction, so that when the automobile brake cylinder housing 10 is placed on the second positioning protrusion 32, it can be restricted by the second positioning protrusion 32 and cannot move further, which plays a certain positioning role. The cooperation between the third positioning protrusion 33 and the third positioning notch 132 refers to the cooperation between the second positioning protrusion 32 and the second positioning notch 131. The first positioning protrusion 31 , the second positioning protrusion 32 and the third positioning protrusion 33 form three supporting points to support the automobile brake cylinder housing 10 , so that the automobile brake cylinder housing 10 can be stably placed on the supporting seat 30 .

[0049] In one embodiment, the automobile brake cylinder housing tooling further includes a pressing rod 60 and a driving mechanism 70 .

[0050] The pressing rod 60 is arranged on the base 20 so as to be movable in the vertical direction, and the lower end of the pressing rod 60 can abut against the upper end of the vehicle brake cylinder housing 10. The driving mechanism 70 is used to drive the pressing rod 60 to move.

[0051] In this embodiment, the arms of the U-shaped part 13 are placed upward on the support seat 30, and the pressing rod 60 moves downward to rest on the automobile brake cylinder housing 10, and the automobile brake cylinder housing 10 is fixed in cooperation with the first positioning protrusion 31, the second positioning protrusion 32 and the third positioning protrusion 33.

[0052] In one embodiment, a plurality of support seats 30 are provided, and the pressing head 51 and the first hydraulic cylinder 50 are provided correspondingly. A plurality of driving mechanisms 70 are provided. A support seat 30 is provided between two adjacent driving mechanisms 70; one driving mechanism 70 can drive two pressing rods 60, one pressing rod 60 is opposite to the second positioning protrusion 32 of one support seat 30, and the other pressing rod 60 is opposite to the third positioning protrusion 33 of the support seat 30 adjacent to the support seat 30. Figure 3 In the embodiment, the left pressing rod 60 on the leftmost driving mechanism 70 is in a neutral state, and the right pressing rod 60 on the rightmost driving mechanism 70 is also in a neutral state.

[0053] In this embodiment, a driving mechanism 70 can simultaneously press the automobile brake cylinder housing 10 on two adjacent support seats 30. The multiple support seats 30 of this tooling are arranged in a line along the same direction, and can be used with other equipment on the production line to place multiple automobile brake cylinder housings 10 for processing. The reverse molded teeth on each pressing head 51 are different, and different marks can be pressed on the automobile brake cylinder housing 10, which is convenient for subsequent traceability. The logo of the pressing head 51 can be different numbers or letters.

[0054] In addition, a step 133 is respectively provided on the outer side of the two arms of the U-shaped member 13, and the two steps 133 are roughly located above the second notch and the third notch. After the lower end of the pressing rod 60 moves downward, it presses on the step 133. The pressing rod 60 cooperates with the second positioning protrusion 32 and the third positioning protrusion 33 to fix the automobile brake cylinder housing 10, which is convenient for the subsequent pressing head 51 to press out the logo on the automobile brake cylinder housing 10. The two pressing rods 60 are roughly located directly above the second positioning protrusion 32 and the third positioning protrusion 33. When the pressing rod 60 moves downward and abuts on the step 133, an external force is applied to fix the automobile brake cylinder housing 10. The pressing rod 60 and the second positioning protrusion 32 and the third positioning protrusion 33 occupy less space together, thereby facilitating the placement of the automobile brake cylinder housing 10.

[0055] In one embodiment, the driving mechanism 70 includes a fixing seat 71 , a second hydraulic cylinder 72 and a driving block 73 .

[0056] The fixing seat 71 is connected to the base 20. The second hydraulic cylinder 72 is disposed in the fixing seat 71. The driving block 73 is connected to the output end of the second hydraulic cylinder 72, and the driving block 73 can move vertically, and both ends of the driving block 73 are connected to the two pressing rods 60 respectively.

[0057] In one embodiment, the lower end of the driving block 73 is connected to a guide rod 74 , and a vertical guide hole 711 is opened on the fixing seat 71 corresponding to the guide rod 74 , and one end of the guide rod 74 away from the driving block 73 is slidably inserted into the guide hole 711 .

[0058] In this embodiment, under the guidance of the guide rod 74, the driving block 73 is not easy to deflect, so that the pressing rods 60 at both ends of the driving block 73 can be pressed against the automobile brake cylinder housing 10 on the same side each time, and the stability is improved.
