Description

Technical Field

[0001] This utility model relates to the field of carbon brush processing equipment technology, and in particular to a closing box mechanism. Background Technology

[0002] The invention patent with application number CN201810580200.7 discloses a carbon brush and a carbon brush box assembly, including a carbon brush box composed of symmetrically installed carbon brush box bodies. The brush box bodies are made of polyoxymethylene. The inner side of the support body is machined with a long groove, and the outer side is machined with a deformation groove. The deformation groove is located below the long groove, and the upper part of the long groove is machined with a guide surface. The carbon brush is formed by a brush body and a carbon brush connecting piece fixedly connected by a compression spring. The bottom of the brush body is curved, and the curved surface matches the outer circle shape of the commutator. The middle part of the carbon brush connecting piece is a narrow section, and the size of the narrow section matches the long groove. The carbon brush connecting piece is fixedly connected to an external wiring device. The brush body, the compression spring, and the carbon brush connecting piece are made of conductive metal. The carbon brush body is inserted into the carbon brush box, and the carbon brush connecting piece is pressed. Through the elastic deformation of the upper part of the carbon brush box body, the carbon brush can be easily installed in the carbon brush box. In actual processing, the ends of the carbon brushes of this product need to be welded to the copper wires of the carbon brushes and closed so that one end of the carbon brush box is closed. However, in current processing, this can often only be done manually or with semi-automatic equipment, which cannot achieve fully automatic online closing of the box, resulting in low efficiency.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Reference Figures 1 to 2The closing mechanism of this utility model includes a mounting clamp 100 and a bending mechanism 200. The mounting clamp 100 is used to clamp the carbon brush with the brush box. The bending mechanism 200 is located below the mounting clamp 100. The bending mechanism 200 includes a driving mechanism and a bending member. The bending member is mounted on the upper end of the driving mechanism and is driven to move up and down by the driving mechanism. The bending member can rise and abut against the end face of the brush box so that the end face of the brush box is bent and covers the end of the brush box.

[0031] In the actual process of closing the brush box, the fixture 100 is used to fix the entire brush box to prevent the brush box from shifting position. Then, the rising bending member is used to bend the end face located below so that the end face covers the end of the brush box, thus completing the closing process. The entire work process is fully automated, which greatly improves efficiency.

[0032] In some embodiments, the bending member is a pivotable roller 220, and the driving mechanism is a first cylinder 210. The driving end of the first cylinder 210 is fixedly connected to a mounting base 230, and the roller 220 is pivotally mounted on the mounting base 230. The first cylinder 210 drives the mounting base 230 to rise, and the mounting base 230 drives the roller 220 located at the top of the mounting base 230 to rise. The roller 220 abuts against the end face of the brush box. As the roller 220 continues to rise, the roller 220 presses the end face, causing the end face to bend and cover the end face of the brush box. Specifically, the front end of the roller 220 near the mounting base 230 can fit against the end face of the brush box, so that the end face of the brush box can tightly cover the end of the brush box.

[0033] It should be mentioned that an elastic element is installed between the brush box and the carbon brush in the mounting fixture 100. When the mounting fixture 100 clamps the carbon brush, the brush box located at the front end of the mounting fixture 100 is prone to protrude beyond the clamping hole 110 under the elastic force of the elastic element. Therefore, specifically, the mounting fixture 100 is provided with a clamping hole 110, and a liftable stop plate 120 is slidably connected above the mounting fixture 100. The stop plate 120 can abut against the end of the brush box to constrain the position of the brush box.

[0034] Furthermore, due to the presence of the stop plate 120, when bending the end face of the brush box, the end face will fit against the stop plate 120, but cannot directly fit against and seal the end of the brush box. In order to ensure that the end face can cover the end of the brush box, in some embodiments, the mounting base 230 includes a fixed base 231 and a swing base 232. The fixed base 231 is fixedly connected to the drive end of the first cylinder 210. One end of the swing base 232 is rotatably connected to the end of the fixed base 231 away from the swing base 232, and the other end is rotatably connected to a roller 220. Driven by external force, the swingable swing base 232 can drive the roller 220 to press against the end face, so that the end face is tightly attached to the end of the brush box. During the swing of the roller 220 toward the mounting fixture 100, the stop plate 120 in the mounting fixture 100 needs to be lifted by the external lifting mechanism.

[0035] To drive the roller 220 to press against the brush box by external force, the closing mechanism of this embodiment of the utility model further includes a pushing mechanism 300, which is used to drive the swing seat 232 to press towards the mounting fixture 100. Specifically, the pushing mechanism 300 includes a second cylinder 310 and a push rod 320, with the second cylinder 310 and the mounting fixture 100 correspondingly arranged; the driving ends of the push rod 320 and the second cylinder 310 are fixedly connected and can extend or retract towards the mounting fixture 100. Under the drive of the second cylinder 310, the push rod 320 can directly abut against the roller 220 and push the swing seat 232 to swing. In order to drive the swing seat 232 to reset after pushing, in some embodiments, a reset mechanism is provided between the swing seat 232 and the fixed seat 231. The reset mechanism drives the swing seat 232 to swing away from the mounting fixture 100. Further, the reset mechanism is a reset spring.

[0036] In the above scheme, the swing seat 232 can be reset under the drive of the return spring. In order to reset the swing seat 232 to the same position, the upper end of the fixed seat 231 is provided with a stop part 2311. The stop part 2311 can abut and cooperate with the swing seat 232 so that the swing seat 232 is in a vertical state.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
