Abstract
Description
Technical Field
[0001] The utility model relates to an improved invention in the field of carbon brush box assembly, in particular to an improved invention for a carbon brush box press-fit bottom die. Background Art
[0002] The function of the carbon brush box is to install the carbon brush and its spring. The spring in the carbon brush box always acts on the carbon brush. The carbon brush box is installed on the PCB board. Usually, the carbon brush box is provided with a carbon brush box foot, and the corresponding PCB board is provided with a mounting hole. The carbon brush box foot is riveted to the PCB board through the mounting hole. During the pre-forming and forming process of the carbon brush box foot by the traditional carbon brush box riveting machine, the carbon brush box lacks internal support during the pressure process, which will be deformed, affecting the subsequent assembly of the carbon brush and the spring and the smoothness of their movement. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a carbon brush box press-fitting bottom die which has stable support and is not easily deformed.
[0004] In order to solve the above technical problems, the utility model is implemented by adopting the following technical scheme: the carbon brush box press-fitting bottom mold includes a base, which is characterized in that: a positioning plate is fixedly provided on the base, and mounting positions for the front brush box, the rear brush box and the PCB board are provided on the positioning plate, and a support block that can move forward and backward is also provided in the mounting position, and the support block can be movably located in the front brush box, the rear brush box or between the front brush box and the rear brush box; a slide groove is provided on the base, and a slider that can move forward and backward is provided in the slide groove, and a thrust spring is provided on the inner side of the slider, and the outer side of the slider cooperates with the cylinder transmission, and the corresponding cylinder shaft can match and extend into the slide groove; the lower end of the support block is connected to the slider through a rod, and a avoidance groove is provided on the corresponding positioning plate.
[0005] The positioning plate is provided with a groove, in which a plurality of inserts are arranged, the inserts enclose a front brush box installation position and a rear brush box installation position, and the positioning plate is also provided with front and rear fixed blocks, and a PCB board installation position is formed between the front and rear fixed blocks.
[0006] The shape of the support block matches the inner cavity of the front and rear brush boxes.
[0007] The beneficial effect of the utility model is that the improved carbon brush box pressing bottom mold can be movably positioned in the front brush box, the rear brush box or between the front brush box and the rear brush box by setting a support block, thereby achieving effective support for the front and rear brush boxes during the gradual riveting and pressing process, thereby avoiding deformation of the carbon brush box. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0009] Figure 1It is a structural schematic diagram of the utility model.
[0010] Figure 2 This is a loading state diagram of the utility model.
[0011] Figure 3 It is a structural sectional view of the utility model. DETAILED DESCRIPTION
[0012] The accompanying drawings show the structure of the utility model, and the following further describes its relevant details in conjunction with the accompanying drawings. Figure 1-3 The carbon brush box press-fitting bottom mold includes a base 1, on which a positioning plate 2 is fixedly provided, and the base 1 and the positioning plate 2 are matched and corresponded up and down. The positioning plate 2 is provided with a mounting position 3 for a front brush box, a rear brush box and a PCB board, and a support block 7 that can be moved forward and backward is also provided in the mounting position 3. The support block 7 can be movably located in the front brush box, the rear brush box or between the front brush box and the rear brush box; a slide groove 4 is provided on the base 1, and a slider 5 that can be moved forward and backward is provided in the slide groove 4, and a thrust spring 6 is provided on the inner side of the slider 5, and the outer side of the slider 5 cooperates with the cylinder transmission, and the corresponding cylinder shaft can match and extend into the slide groove 4; the lower end of the support block 7 is connected to the slider 5 through a rod 8, and the corresponding positioning plate 2 is provided with an avoidance groove 9.
[0013] The working principle of the utility model is that the support block 7 is linked with the slider 5, the support block 7 is driven forward by the thrust spring 6 to be located in the front brush box to support the front brush box, the support block 7 is driven backward by the cylinder to be located between the front and rear brush box installation positions for loading the front and rear brush boxes, and the support block 7 is driven backward by the cylinder to be located in the rear brush box to support the rear brush box, wherein the rod 8 is used to connect the support block 7 and the slider 5 to form a linkage structure, the rod 8 can enter the brush braid groove of the carbon brush box, so that the support block 7 can enter the front and rear brush boxes without restriction.
[0014] As a further improved specific implementation method, a groove is opened on the positioning plate 2, and a plurality of inserts 10 are arranged in the groove. The inserts 10 enclose a front brush box mounting position and a rear brush box mounting position. The positioning plate 2 is also provided with front and rear fixed blocks 11, and a PCB board mounting position is formed between the front and rear fixed blocks 11. The inserts 10 and the positioning blocks 11 are respectively used to form the front and rear brush box mounting positions and the PCB board mounting positions, which is convenient for controlling the size of the mounting position to meet the installation requirements of carbon brush boxes of different sizes.
[0015] As a further improved specific implementation method, the shape of the support block 3 matches the inner cavity of the front and rear brush boxes to form a better support.
[0016] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
