DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort belong to the scope of protection of the present application.

[0027] The embodiments of the present application provide a pushing device, which can solve the problem in the related art that if there are iron filings remaining on the cylinder hole surface, the pressure applied by the pressing block can cause pressure marks on the surface, which not only affects the overall appearance quality of the workpiece, but also because of the high requirement of the cylinder hole surface on the sealing performance, the pressure marks can greatly reduce the sealing effect.

[0028] Embodiment 1

[0029] As shown in Figures 1-3 A pushing device, comprising: a mounting seat 1 and a sliding block 3, the sliding block 3 being slidingly connected to the mounting seat 1.

[0030] In the embodiment, the pressing mechanism comprises a plurality of pressing assemblies, the plurality of pressing assemblies are circumferentially arranged along the mounting base 1, and the sliding block 3 can drive the plurality of connecting members 4 to rotate, so that the plurality of fasteners 5 press or release the workpiece 10.

[0031] One end of the workpiece 10 on both sides of the mounting base 1 is fixed, and the other end is placed between the two pressing assemblies. The driving mechanism 6 drives the sliding block 3 to move along the non-machining end, so that the connecting member 4 rotates around its rotation point. The left connecting member 4 rotates clockwise, and the right connecting member 4 rotates counterclockwise, thereby pushing the fastener 5 close to the inner side of the workpiece 10 to tightly press the other end of the workpiece 10. Conversely, when the sliding block 3 moves along the machining end, the connecting member 4 rotates reversely around its rotation point. The left connecting member 4 rotates counterclockwise, and the right connecting member 4 rotates clockwise, thereby pushing the fastener 5 away from the inner side of the workpiece 10 to release the other end of the workpiece 10. Through a pushing and pressing device, the workpiece 10 on both sides can be pressed and released at the same time, which not only saves the pressing space, but also improves the machining efficiency. Since the cylinder hole surface needs to meet strict sealing conditions, the flatness of the surface must be ensured. In comparison, the claw surface does not have special requirements for the surface roughness because it directly contacts the brake disc. The fastener 5 only contacts the inner side of the claw surface, avoiding direct contact with the cylinder hole surface, thereby ensuring the overall quality of the brake caliper.

[0032] In some optional embodiments, the pressing mechanism comprises a plurality of pressing assemblies, the plurality of pressing assemblies are circumferentially arranged along the mounting base 1, and the sliding block 3 can drive the plurality of connecting members 4 to rotate, so that the plurality of fasteners 5 press or release the workpiece 10.

[0033] Further, the mounting base 1 is fixedly connected with a fixed seat 2, the fixed seat 2 is fixedly connected with a driving mechanism 6, the driving mechanism 6 is a hydraulic cylinder, the sliding block 3 is provided with a mounting groove 7 for hinging the output shaft of the hydraulic cylinder, and a gap is reserved between the output shaft and the inner wall of the mounting groove 7. The gap allows the sliding block 3 to swing left and right around the hinge point, ensuring that the two pressing assemblies do not interfere with each other and completing the pressing action without interference.

[0034] In some optional embodiments, the driving mechanism 6 can also be a gas cylinder or other electric driving mechanism.

[0035] Further, the sliding block 3 is provided with a limiting groove 8, the length direction of the limiting groove 8 is arranged along the movement direction of the workpiece 10, and one end of the connecting member 4 is slidably connected to the sliding block 3 through the limiting groove 8.

[0036] Further, the fastener 5 is provided with a groove 504 at the bottom, and the connecting member 4 drives the fastener 5 to move through the groove 504 at the upper end.

[0037] Further, the connecting piece 4 is V-shaped, and the openings of the connecting pieces 4 of the two pressing assemblies are oppositely arranged to realize pressing and loosening on both sides.

[0038] Further, the middle of the mounting seat 1 is provided with a first cavity 101, a second cavity 102 and a sliding groove 103 which are communicated with each other, the first cavity 101 is used for the movement of the sliding block 3 along the workpiece processing end, the second cavity 102 is used for the rotation of the connecting piece 4, and the fastener 5 is slidingly connected with the sliding groove 103 in the vertical direction of the movement direction of the sliding block.

[0039] Further, the fastener 5 includes a sliding seat 501 which is slidingly connected with the mounting seat 1, a groove 504 is arranged at the bottom of the sliding seat 501, one end of the sliding seat 501 is fixedly connected with a supporting rod 502, and the upper end of the supporting rod 502 is fixedly connected with a clamping arm 503.

[0040] Embodiment 2:

[0041] A pushing device, which is different from the embodiment 1 in that the connecting piece 4 is V-shaped, and the openings of the connecting pieces 4 of the two pressing assemblies are oppositely arranged.

[0042] Due to the different arrangement directions of the openings of the connecting pieces 4, the movement direction of the device is different from that of the embodiment 1. Specifically, one end of the workpiece 10 on both sides of the mounting seat 1 is fixed, and the other end is placed between the two pressing assemblies, the driving mechanism 6 drives the sliding block 3 to move along the non-processing end, so that the connecting piece 4 rotates around its rotation point, the left connecting piece 4 rotates counterclockwise, and the right connecting piece 4 rotates clockwise, thereby pushing the fastener 5 away from the workpiece 10 to loosen the other end of the workpiece 10. Conversely, when the sliding block 3 moves along the processing end, the connecting piece 4 rotates reversely around its rotation point, the left connecting piece 4 rotates clockwise, and the right connecting piece 4 rotates counterclockwise, thereby pushing the fastener 5 to approach the workpiece 10 to press the other end of the workpiece 10.

[0043] Embodiment 3:

[0044] As shown in Figure 4 A limiting tool, which includes the pushing device in the above-mentioned embodiment 1, and the side wall of the mounting seat 1 is provided with a limiting device, the limiting device is symmetrically arranged on both sides of the pushing device, and the limiting device and the pushing device jointly fix the workpieces 11 on both sides.

[0046] Further, the limiting device can also be a positioning groove which is arranged on the mounting seat 1, the positioning groove is matched with the shape of the workpiece, and is used for supporting the workpiece 10 and limiting the movement of the workpiece in the vertical direction.

[0047] The working principle of the present application is as follows:

[0048] The positioning hole at one end of the workpiece 10 is inserted into the plurality of limiting columns 10, and the other end is placed between the two pressing assemblies, the hydraulic cylinder drives the sliding block 3 to move along the non-machining end, the limiting groove 8 makes the connecting piece 4 rotate around its rotation point, the left connecting piece 4 rotates clockwise, and the right connecting piece 4 rotates counterclockwise, thereby pushing the fastener 5 close to the inner side of the workpiece 10 and tightly pressing the other end of the workpiece 10. Conversely, when the sliding block 3 moves along the machining end, the limiting groove 8 makes the connecting piece 4 rotate reversely around its rotation point, the left connecting piece 4 rotates counterclockwise, and the right connecting piece 4 rotates clockwise, thereby pushing the fastener 5 away from the inner side of the workpiece 10 and loosening the other end of the workpiece 10. Through a pushing device, the inner sides of the workpieces 10 on both sides can be simultaneously tightened and loosened, not only saving the pressing space, but also improving the machining efficiency.

[0049] Since there is a gap between the output shaft of the hydraulic cylinder and the inner wall of the mounting groove 7, the sliding block 3 can swing left and right around the hinge point, ensuring that the two pressing assemblies do not interfere with each other and completing the pressing action without interference.
