[0021] The present invention provides a special press-fitting device for an automotive brake lever and a limit gasket, including a bottom plate 1, a base 2, a positioning bolt 3, a vertical plate 4, a horizontal plate 5, a cylinder group 6, a pressing member 7, a pressing member 7, a connecting plate 8, a positioning rod 9, and a control device.

[0022] The base 2 is a U-shaped seat, and one side of the base 2 is fixedly connected to the upper end of the bottom plate 1 by screw cooperation. On the upper end surface of the open end of the base 2, symmetrically distributed grooves 21 are provided, and the shape of the grooves 21 fits the outer arc surface of the double-headed end of the brake lever 10. A positioning bolt 3 is threadedly connected above the closed end of the base 2, and the upper semi-circular head of the positioning bolt 3 fits the lower groove of the single-headed end of the brake lever 10. As can be seen from the accompanying drawings of the specification, the brake lever 10 is fixedly placed on the base 2 through the cooperation with the grooves 21 and the positioning bolt 3.

[0023] Vertical plates 4 are symmetrically arranged on both sides of the base 2, and the vertical plates 4 are perpendicularly distributed with respect to the symmetry axis of the base 2; the lower ends of the vertical plates 4 are fixedly connected to the bottom plate 1 by screw cooperation. A cross plate 5 is commonly arranged above the two vertical plates 4, and the cross plate 5 and the two vertical plates 4 form an inverted U-shaped structure; both ends of the cross plate 5 are fixedly connected to the upper ends of the vertical plates 4 by screw cooperation. An air cylinder group 6 is arranged above the cross plate 5, and the air cylinder group 6 includes a first air cylinder 61 and a second air cylinder 62; the first air cylinder 61 and the second air cylinder 62 are sequentially located above the cross plate 5; the cross plate 5, the first air cylinder 61 and the second air cylinder 62 are fixedly connected by long bolts.

[0024] The push rod of the first air cylinder 61 passes through the center of the cross plate 5 and extends below the cross plate 5. The pressing member 7 includes a connecting portion 71, a pressing portion 72 and a sliding block 73, which are integrally processed. The pressing portion 72 is a cylinder that fits the inner arc surface of the limiting gasket 11; the pressing portions 72 are symmetrically distributed at both ends of the connecting portion 71; the sliding block 73 is located at the end of the pressing portion 72 away from the connecting portion 71. The push rod end of the first air cylinder 61 extends into the center position of the connecting portion 71 and is fixedly connected to the connecting portion 71 by bolts. The pressing member 7 is located below the cross plate 5; vertically arranged guiding grooves 41 that cooperate with the sliding blocks 73 are respectively provided on the inner sides of the two opposite vertical plates 4. The pressing member 7 is located between the two vertical plates 4, and the sliding blocks 73 at both ends of the pressing member 7 are respectively slidably fitted in the guiding grooves 41 on both sides of the pressing member 7.

[0025] As can be seen from the above in combination with the accompanying drawings of the invention book, by driving the first air cylinder 61, the push rod of the first air cylinder 61 is extended, pushing the pressing member 7 to move downward. The pressing member 7 is limited by the cooperation of the sliding blocks 73 and the guiding grooves 41, ensuring that the pressing member 7 does not shift in position during the movement. The downward movement of the pressing member 7 presses the limiting gasket 11 through the pressing portion 72, so that the limiting gasket 11 is compacted and assembled on the brake lever 10.

[0026] The push rod end of the second cylinder 62 extends into the central position of the connecting plate 8 and is fixed to the connecting plate 8 by bolt cooperation; the connecting plate 8 is located above the second cylinder 62.

[0027] As can be seen from the above in combination with the attached drawings of the invention book, before driving the first cylinder 61 to press-fit the limit gasket 11 onto the brake lever 10, by driving the second cylinder 62, the push rod of the second cylinder 62 is retracted, driving the positioning rod 9 to move downward. During the downward movement of the positioning rod 9, it successively passes through the positioning holes of the brake lever 10 and the limit gasket 11, aligning the positioning holes of the limit gasket 11 and the brake lever 10, thereby positioning the limit gasket 11 in the press-fitting direction of the brake lever 10 and ensuring the accuracy of press-fitting and the press-fitting quality of the product.

[0028] The control device includes a first solenoid valve, a second solenoid valve and a time control switch; the first solenoid valve is arranged on the air inlet pipeline of the first cylinder 61; the second solenoid valve is arranged on the air inlet pipeline of the second cylinder 62; both the first solenoid valve and the second solenoid valve are connected to the time control switch.

[0029] It can be seen that by using two groups of solenoid valves to control the first cylinder 61 and the second cylinder 62 respectively to perform two actions of gasket positioning and gasket press-fitting, and then designing the time control switch to be connected to the two groups of solenoid valves to achieve sequential control of the two actions with an action holding function, which is convenient for subsequent automation transformation.

[0030] The specific usage method and function of this embodiment:

[0031] First, the brake lever 10 is placed on the base 2 through the cooperation of the groove 21 and the positioning bolt 3 manually or by an automated machine. Then, the limit spacer 11 is placed at the inner arc press-fitting position on the brake lever 10, and the positioning holes of the limit spacer 11 and the brake lever 10 are initially aligned. After that, the second cylinder 62 is driven to retract the push rod of the second cylinder 62, controlling the positioning rod 9 to move downward by a certain distance, so that the positioning rod 9 passes through the positioning holes of the limit spacer 11 and the brake lever 10, realizing the accurate positioning of the limit spacer 11 on the brake lever 10. Finally, the first cylinder 61 is driven to extend the push rod of the first cylinder 61, controlling the pressing member 7 to move downward by a certain distance. The pressing member 7 pushes the limit spacer 11 downward through the pressing portion 72, so that the limit spacer 11 is pressed and assembled on the brake lever 10. After the press-fitting is completed, the first cylinder 61 and the second cylinder 62 are driven in sequence to control the pressing member 7 to rise and reset, and control the positioning rod 9 to rise and reset, so that the positioning rod 9 leaves the positioning holes of the brake lever 10 and the limit spacer 11. After that, the product after the press-fitting can be taken out from the base 2 to complete the press-fitting operation of one product, and then the above actions are cycled to press-fit the new brake lever 10 and the limit spacer 11.

[0032] In summary, compared with the current manual press-fitting operation, the operation of the present utility model is simple, the labor intensity of workers is low, the production efficiency is high, and the press-fitting quality of the product is stable.
