[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] Example 1:

[0023] See also Figures 1-4 The present invention provides a spring fixing device for a brake spring used in a brake, comprising a bracket 1, a connecting plate 2, and a spring 3. Two limiting grooves are provided at the left and right ends of the bracket 1. Limiting components for limiting the spring 3 are provided at the left and right parts of the bracket 1. The limiting components include two limiting plates 6, each of which is inserted into the interior of a corresponding limiting groove.

[0024] Positioning plates 7 are provided on the left and right sides of the bracket 1. The right end of the left positioning plate 7 is fixedly connected to the left end of the left limiting plate 6, and the left end of the right positioning plate 7 is fixedly connected to the right end of the right limiting plate 6. A frame shaft 5 is fixedly connected between the two limiting plates 6 located in the same limiting assembly, and an annular groove is provided in the middle of each frame shaft 5; the frame shaft 5 passes through the mounting hole of the spring 3, and the other end of the spring 3 is hooked with the connecting plate 2. The left and right ends of the bracket 1 are provided with grooves corresponding to the positioning plates 7.

[0025] During installation, the spring 3, connecting plate 2, frame shaft 5 and positioning plate 7 are installed together at the same time, and then the whole is installed on the bracket 1. By pulling the spring 3, the positioning plate 7 is stuck in the groove of the bracket 1, and the installation is completed; when in use, after the spring 3 slides, the blocking plate 10 limits the position of the spring 3, reducing the position deviation of the spring 3, and during installation, the positioning plate 7 can be pulled by a mechanical device, and then each spring 3 can be pulled, which makes it easier for the mechanical device to pull the spring 3, instead of the mechanical device pulling the spring 3, and thus facilitates the connection with the automated mechanical equipment.

[0026] Furthermore, the left and right ends of the bracket 1 are fixedly connected with a cam 8, and each cam 8 passes through the middle of each corresponding positioning plate 7. The rear end of the positioning plate 7 is provided with a long groove that cooperates with the cam 8. The position of the positioning plate 7 is limited by the cam 8, thereby reducing the possibility of the positioning plate 7 falling off and shifting on the bracket 1 during use; each cam 8 is threadedly connected with a nut 9, and the position of the positioning plate 7 is limited by the nut 9, further reducing the possibility of the positioning plate 7 falling off inside the groove of the bracket 1.

[0027] Two arc grooves are provided on the connecting plate 2, and a clearance groove is provided at the end of each arc groove. The shape of the arc groove and the clearance groove facilitates the guidance of the position of the spring 3, thereby facilitating the connection between the spring 3 and the connecting plate 2.

[0028] In addition, the outer wall of the connecting plate 2 is connected to a baffle 4, which is located at the hook of each spring 3. The baffle 4 limits the position of the spring 3, reduces the skewness of the contact between the spring 3 and the connecting plate 2, and thereby improves the stability of the spring 3 installed at the connecting plate 2.

[0029] Furthermore, the upper and lower parts of the baffle 4 are fixedly connected to the fixing box 15, and the interior of each fixing box 15 is provided with a cavity, and the upper and lower parts of each fixing box 15 are provided with a convex plate 11, and the rear end of each convex plate 11 is fixedly connected to the card block 16, and the connecting plate 2 is provided with a T-shaped slot corresponding to the card block 16; one end of each convex plate 11 away from the middle of the fixing box 15 is fixedly connected to the limiting shaft 12, and each limiting shaft 12 passes through the side wall of the fixing box 15, and the outside of each limiting shaft 12 is provided with a positioning spring 13, which is located in the fixing box 1 5; one end of each limiting shaft 12 away from the convex plate 11 is fixedly connected with a sliding cover 14, and the sliding cover 14 is mounted on the fixing box 15. When the user installs it, the user presses the sliding cover 14 to make the two sliding covers 14 approach each other, thereby driving the convex plate 11, the limiting shaft 12 and the card block 16 to approach each other, so that the card block 16 can be inserted into the T-slot, and the card block 16 is inserted into the T-slot on the connecting plate 2. Then, the sliding cover 14 is released, so that the card block 16 and the T-slot are matched, and then the card block 16 is positioned, which is convenient for the user to operate.

[0030] Example 2:

[0031] On the basis of Example 1, a blocking plate 10 is provided at the contact point between the inner wall of the bracket 1 and the frame shaft 5, and an adhesive is applied at the contact point between the blocking plate 10 and the inner wall of the bracket 1. The position of the frame shaft 5 is limited by the blocking plate 10, and the blocking plate 10 is installed after the spring 3 is installed on the bracket 1 to further reduce the position displacement of the spring 3 during use, and the blocking plate 10 is fixed to the bracket 1 by the adhesive. The concentration of the adhesive is selected to be relatively low and is only used to fix the position of the blocking plate 10.

[0032] The present invention also provides a method for installing a brake spring for a brake, comprising the following steps:

[0033] During installation, connect the bracket 1 and the brake, then insert the hook of the spring 3 into the arc groove of the connecting plate 2, and the user presses the sliding cover 14 to make the two sliding covers 14 approach each other, thereby driving the convex plate 11, the limiting shaft 12 and the card block 16 to approach each other, so that the card block 16 can be inserted into the T-slot, and insert the card block 16 into the T-slot on the connecting plate 2; then loosen the sliding cover 14, so that the card block 16 and the T-slot cooperate, and then position the card block 16 so that the baffle 4 limits the position of the spring 3, and then hook the spring 3 on the frame shaft 5, and then drive the two positioning plates 7 away from each other through the clamp on the manipulator, put the positioning plate 7 on the bracket 1, insert the limiting plate 6 into the corresponding limiting groove, and extend the positioning plate 7 into the groove of the bracket 1, and then connect the nut 9 and the convex shaft 8 to complete the overall installation process.
