[0034] The device can be applied to existing brake caliper unit products of railway locomotives and vehicles, and can be used for automatic discharging and oil injection of disc springs 8 of brake cylinders, that is, automatically pushing out disc springs 8 one by one, and spraying oil on disc springs 8. The brake cylinder mentioned in this article is an air brake. When in use, a stack of disc springs 8 is placed in a disc spring placement groove 5, and the push plate 3 is driven to move by the driving device 2, so that the disc spring 8 at the bottom layer in the disc spring placement groove 5 can be pushed forward, and the disc spring 8 in the disc spring oil injection chamber 6 can be pushed to the disc spring taking groove 7, completing the pushing out and oil injection of a single disc spring 8.

[0035] Therefore, the disc spring pushing device in this embodiment can automatically complete the placement and removal of the disc spring 8 and the automatic oil spraying of the disc spring 8 through the cooperation of the driving device 2, the pushing plate 3, the disc spring placement groove 5, the disc spring oil spraying chamber 6 and the disc spring taking groove 7, and can push out the disc springs 8 one by one, avoiding errors, saving labor costs, and being more efficient.

[0036] In a specific implementation, an anti-deflection block 4 is provided on the support seat 1 and between the disc spring placement groove 5 and the push plate 3, and an anti-deflection channel is formed between the anti-deflection block 4 and the support seat 1; the shape of the push plate 3 and the shape of the anti-deflection channel both match the shape of the disc spring 8, and the push plate 3 can be movably inserted in the anti-deflection channel.

[0037] The setting of the anti-deviation channel can guide the push plate 3 during its movement, prevent the push plate 3 from deflecting, ensure that the push plate 3 is always in a horizontal state, and ensure that the push plate 3 only pushes one disc spring 8 forward each time.

[0038] The end of the push plate 3 away from the driving device 2 has a notch 31, and the shape of the notch 31 matches the edge contour of the disc spring 8. After the push plate 3 is extended, the notch 31 at its end can be close to the edge of the disc spring 8 to push the disc spring 8 out more stably.

[0039] The shape of the push plate 3 matches the shape of the corresponding single-piece disc spring 8, and the thickness of the push plate 3 is the same as the thickness of the corresponding disc spring 8. It is a contoured push plate, and the cross-sectional shape of the anti-deflection channel is the same as the cross-sectional shape of the push plate 3.

[0040] The number of groups of the push disc spring assembly is determined according to the number of types of disc springs 8 required. For example, in this embodiment, two types of disc springs 8 are mainly used, one type is a flat disc spring 8 (such as Figure 3 As shown), the corresponding push plate 3 is a rectangular flat plate structure (as shown Figure 5 As shown), the anti-deflection channel is a rectangular flat channel; the other is a saddle-shaped disc spring 8 (as shown Figure 4 As shown), the corresponding push plate 3 is an arc-shaped plate (as shown Figure 6 As shown), the anti-deflection channel is also a corresponding arc-shaped channel. Therefore, the number of the push disc spring assemblies in this embodiment is two groups.

[0041] Furthermore, in order to facilitate the placement of more disc springs 8, a plurality of columns 51 are provided on the support seat 1 around the disc spring placement groove 5, and a pressure block 52 that can move up and down is provided between the plurality of columns 51. The pressure block 52 can be pressed against the disc spring 8 located on the current top layer in the disc spring placement groove 5 under the action of gravity.

[0042] The number of columns 51 is determined according to the needs. For example, in this embodiment, there are four columns 51. After stacking a plurality of disc springs 8 in a stack in the disc spring placement slot 5, the moving pressing block 52 is pressed against the disc spring 8 at the current top layer to limit the position. When the disc springs 8 are continuously pushed out from the bottom layer, the number of the stacked disc springs 8 decreases, the overall height decreases, and the pressing block 52 automatically descends under the action of gravity to press against the disc spring 8 at the current top layer.

[0043] The above-mentioned disc spring oil spray chamber 6 has an inlet and an outlet 61 arranged opposite to each other, and the shapes of the inlet and the outlet 61 match the shape of the disc spring 8, and specifically, the shapes of the inlet and the outlet 61 are the same as the cross-sectional shape of the push plate 3. The disc spring 8 can be pushed into the disc spring oil spray chamber 6 through the inlet, and then pushed out through the outlet 61 after oil is sprayed. Generally, a pipe joint is connected to the top of the disc spring oil spray chamber 6, and the pipe joint is connected to an oil pipe, so that oil can be automatically injected into the disc spring oil spray chamber 6.

[0044] The disc spring taking groove 7 is composed of a groove-shaped box body with an opening at the top, and the outlet 61 of the disc spring spray chamber 6 is connected to a groove wall on one side of the disc spring taking groove 7. When the push plate 3 pushes the disc spring 8 into the disc spring spray chamber 6, the previous disc spring 8 can be pushed out into the disc spring taking groove 7. In order to facilitate the operator to take out the disc spring 8 that has been sprayed with oil, a bottom hole 71 is opened at the bottom of the disc spring taking groove 7 for easy taking.

[0045] To facilitate processing and installation, the support seat 1 includes a support base plate 11 and a driving support frame 12 and a disc spring support frame 13 fixed on the support base plate 11. A movable groove 131 extending along the above-mentioned horizontal moving direction and penetrating the first end face and the second end face of the disc spring support frame 13 is provided on the top face of the disc spring support frame 13; the anti-deflection block 4 is arranged on the movable groove 131 and close to the first end face of the disc spring support frame 13, and is enclosed with the bottom of the movable groove 131 to form the above-mentioned anti-deflection channel.

[0046] An oil spray cover 62 is provided on the movable groove 131 and near the second end surface of the disc spring support frame 13. The oil spray cover 62 and the movable groove 131 enclose the above-mentioned disc spring oil spray chamber 6, and the bottom two side surfaces of the oil spray cover 62 and the groove bottom of the movable groove 131 enclose the above-mentioned inlet and outlet 61, and the pipe joint is installed on the top surface of the oil spray cover 62. The part of the movable groove 131 located between the anti-deflection block 4 and the oil spray cover 62 constitutes the above-mentioned disc spring placement groove 5, and a plurality of columns 51 are fixed on the disc spring support frame 13 on both sides of the movable groove 131.

[0047] The driving device 2 can be, for example, a cylinder, whose cylinder body is fixed on the driving support frame 12, and the end of its piston rod is fixedly connected to the end of the push plate 3, and the other end of the push plate 3 can be moved into the anti-deviation channel.

[0048] In more detail, the specific working process of the push disc spring device is:

[0049] The stack of disc springs 8 is stacked in the disc spring placement slot 5, and the pressing block 52 is moved to press the disc springs 8. The driving device 2 works, driving the push plate 3 to move forward along the anti-deflection channel, and pushing the disc spring 8 at the bottom layer in the disc spring placement slot 5 forward, pushing it into the disc spring oil spraying chamber 6 from the inlet of the disc spring oil spraying chamber 6, and automatically spraying oil on the disc spring 8 using the oil pipe connected to the pipe joint; then the push plate 3 continues to push the next disc spring 8, pushing the disc spring 8 currently at the bottom layer in the disc spring placement slot 5 forward, and when the disc spring 8 is pushed into the disc spring oil spraying chamber 6, the previous disc spring 8 originally located in the disc spring oil spraying chamber 6 can be pushed into the disc spring taking slot 7, and the operator takes the disc spring 8 after oil spraying from the disc spring taking slot 7 to proceed to the next process.

[0050] The push plate 3 is designed to match the single disc spring 8, so that the single disc spring 8 can be automatically pushed out. The pushed disc spring 8 enters the disc spring oil injection chamber 6, and the previous disc spring 8 can be pushed out when the next disc spring 8 is pushed out. By setting the corresponding degree, the disc spring 8 can be automatically pushed out according to the set number, and a fixed number of disc springs 8 can be pushed out, avoiding the error in the number of disc springs 8, and playing a mistake-proofing function; the disc spring 8 can be automatically oiled while being pushed out, which improves the assembly efficiency.

[0051] The above is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
