Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts manufacturing, in particular to a press-fitting mechanism for installing a compression spring of a disc brake lining. Background Art

[0002] The disc brake lining includes a back plate, a friction layer attached to the back plate, and a compression spring. The compression spring is placed on the side of the back plate. Two protrusions are arranged on the back plate and embedded in openings arranged at both ends of the compression spring. The middle part of the compression spring is connected to the back plate through a fastener. When assembling the disc brake lining, one end of the fastener is usually inserted into the hole on the back plate, and the other end of the fastener is pressed on the outside of the compression spring. The other end of the fastener is bent so that the two ends of the fastener are butted, and finally the two ends of the fastener are welded. The above-mentioned assembly process of the existing disc brake lining is mostly completed manually. Since it is necessary to ensure that the fastener presses the middle part of the compression spring toward the back plate, during the assembly process, the operator needs to compress the middle part of the retaining spring and then bend the fastener to ensure that the two ends of the fastener can be butted. Since both the compression spring and the fastener need to be compressed during assembly, the installation is difficult, the efficiency is low, and the labor cost is high. Utility Model Content

[0021] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0022] like Figure 1, 2 As shown in Figure 3, a press-fitting mechanism for installing a compression spring of a disc brake lining of the utility model comprises a workbench 10, a positioning assembly, a lateral clamping assembly and a vertical clamping assembly. In the figure, the X direction is the length direction of the workbench 10, the Y direction is the width direction of the workbench, and the Z direction is the height direction of the workbench 10. A support surface 101 is formed on the workbench 10, and the support surface 101 is used to place the brake lining 90. The upper surface of the workbench 10 is a plane, and the above-mentioned support surface 101 can be formed by the upper surface of the workbench 10. The brake lining 90 can be placed flat on the support surface 101. In addition, a support member 50 is also provided on the workbench 10, and the support member 50 is used to support the fastener 92 of the brake lining 90; the positioning assembly is installed on the workbench 10, and is used to position the brake lining 90 located on the support surface 101. The transverse clamping assembly is installed on the workbench 10, which is arranged opposite to the positioning assembly and arranged along the Y direction. The transverse clamping assembly includes a clamping piece 30 and a first cylinder 31. The cylinder body of the first cylinder 31 is fixedly connected to the workbench 10, and the telescopic rod is connected to the clamping piece 30. Thus, the clamping piece 30 is driven by the first cylinder 31 to move between a first position close to the positioning assembly and a second position away from the positioning assembly. The clamping piece 30 includes two clamping arms 32. The clamping arms 32 form an extrusion slope 33 on the surface of the positioning assembly. The extrusion slope 33 gradually inclines from the outside to the inside toward a direction away from the positioning assembly. In this way, the extrusion slopes 33 on the two clamping arms 32 roughly constitute a V-shaped structure, and the two sides of the compression spring 91 on the brake lining 90 are respectively squeezed by the two extrusion slopes 33, so that the compression spring 91 is as close to the brake lining 90 as possible. The vertical clamping assembly includes a pressing member 40 located directly above the support member 50, and a second cylinder 41 for driving the pressing member 40 to move up and down. When driving the pressing member 40 to move downward, the second cylinder 41 can press the fastener 92 on the brake pad 90 downward to bend the fastener 92.

[0023] During use of the utility model, the brake lining 90 is placed on the supporting surface 101, and the brake lining 90 is positioned by using the positioning assembly so that the hole on the supporting lining 90 for inserting the fastener 92 is located above the supporting member 50, and then the compression spring 91 is placed on the brake lining 90 so that the holes at both ends of the compression spring 91 are buckled on the two protrusions of the brake lining, and then the first cylinder 31 is started to push the clamping member 30 to move toward the first position. When the clamping member 30 moves to the first position, the compression spring 91 is pressed against the supporting lining under the pressure of the two extrusion inclined surfaces 33. At this time, one end of the fastener 92 is inserted from bottom to top into the hole of the brake lining 90, and the supporting member 50 is supported under the fastener 92, and finally the second cylinder 41 is started to drive the pressing member 40 to move downward, and the pressing member 40 presses the other end of the fastener 92 downward to combine the two ends of the fastener 92, and finally the seams at both ends of the fastener 92 are welded to complete the assembly of the brake lining 90. In the utility model, the brake lining is positioned by using a positioning assembly, and the two extrusion inclined surfaces on the clamping member compress the compression spring so that the compression spring is close to the brake lining. The downward movement of the lower pressing member is used to squeeze the fastener supported on the supporting member downward, so that the fastener is bent to complete the docking of the two ends of the fastener. There is no need to manually compress the compression spring and bend the fastener, which reduces the difficulty and labor cost of assembling the brake lining and realizes the rapid assembly of the brake lining.

[0024] It should be noted that the first cylinder 31 and the second cylinder 41 mentioned above may be replaced by oil cylinders, hydraulic cylinders, electric cylinders or other driving units.

[0025] In a preferred embodiment, an avoidance recess 34 is formed between the two clamping arms 32, and the avoidance recess 34 is used to avoid the fastener 92 of the brake lining 90 when the clamping member 30 is in the first position. That is, when the two extrusion slopes 33 press the compression spring 91 to the edge of the brake lining 90, the fastener 92 can be embedded between the two avoidance recesses 34 so that one end of the fastener 92 can pass through the hole on the brake lining 90 from bottom to top.

[0026] In the utility model, the positioning assembly includes two first positioning columns 21 respectively located on both sides thereof, and at least one second positioning column 22. The second positioning column 22 is located on a side of the positioning assembly away from the lateral clamping assembly. The first positioning column 21 and the second positioning column 22 protrude from the support surface 101 to form a positioning space on the support surface 101 for accommodating the brake lining 90. The brake lining 90 is placed in the positioning space so that the two sides of the brake lining 90 are respectively abutted against the two first positioning columns 21. When the clamping member 30 presses the compression spring 91 against the brake lining 90, the side of the brake lining 90 away from the clamping member 30 is abutted against the second positioning column 22. In this way, while the clamping member 30 compresses the compression spring 91, the brake lining 90 is also compressed to accurately position the brake lining 90.

[0027] A door-shaped bracket 11 is arranged on the workbench 10, and the bottoms of both sides of the door-shaped bracket 11 are fixedly connected to the workbench 10, and the crossbeam on the top of the door-shaped bracket 11 extends along the X direction. The cylinder body of the second cylinder 41 is fixedly connected to the crossbeam of the door-shaped bracket 11, and the telescopic rod of the second cylinder 41 extends downward and is fixedly connected to the lower pressure piece 40.

[0028] In some embodiments, the above-mentioned support member 50 is fixedly set on the workbench 10, and is used to support the fastener 92 when the lower pressure member 40 squeezes the fastener 92 downward to bend the fastener 92. In a preferred embodiment, the utility model arranges the support member 50 to be movable up and down, and uses a third cylinder 51 to drive the support member 50 to move up and down. The third cylinder 51 can also be replaced by an oil cylinder, a hydraulic cylinder, an electric cylinder or other driving units. The support member 50 is arranged to be movable up and down. When the fastener 92 is inserted into the hole of the brake lining from bottom to top, the support member 50 is in a lower position. In this way, there is enough space between the support member 50 and the brake lining 90 for the fastener 92 to be placed. After the fastener 92 is inserted into the hole of the brake lining 90, the third cylinder 51 is used to drive the support member 50 to move upward to a high position to tighten the fastener 92 from below. The cylinder body of the third cylinder 51 is fixedly connected to the lower surface of the workbench 10 , the telescopic rod passes upward through a preset through hole on the workbench 10 and then protrudes from the upper surface of the workbench, and the support member 50 is fixed on the telescopic rod of the third cylinder 51 .
