Description

Technical Field

[0002] The brake shoe generally includes an arc-shaped body and an arc-shaped plate fixed in the arc of the body. The arc-shaped plate is provided with a plurality of connection holes. During the processing, the brake shoe can be positioned by using these connection holes, and then the outer circle grinding process is performed. In the prior art, the outer circle grinding device generally includes a rotating grinding wheel driven by a driving motor. During processing, the brake shoe is clamped and positioned by a clamp, and then the rotating grinding wheel is moved to make it contact with the outer wall of the body, so as to achieve grinding. In order to make the rotating grinding wheel contact with the outer wall of the entire arc-shaped body, the rotating grinding wheel needs to be in a continuous moving state and also needs to rotate. During the process, the spray angle of the grinding liquid needs to be adjusted to adapt to the movement of the rotating grinding wheel (the grinding liquid needs to be sprayed to the contact point between the rotating grinding wheel and the body). Therefore, the structure of the entire device is relatively complex, which may lead to a high failure rate and high maintenance costs. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0023] In an exemplary embodiment, Figure 1-3 As shown, the present embodiment provides a brake shoe outer circle grinding device, which comprises a horizontally disposed mounting plate 1, a rotating grinding wheel 2 is mounted on one end of the mounting plate 1, a telescopic drive 3 is fixedly mounted on the other end, and a movable plate 4 is also mounted between the telescopic drive 3 and the rotating grinding wheel 2, the movable plate 4 is connected to the telescopic drive 3 so as to approach or move away from the rotating grinding wheel 2 under the drive of the telescopic drive 3; a first driving motor 5 is also fixedly mounted below the movable plate 4, a rotating shaft of the first driving motor 5 is fixedly connected to a mounting shaft 6, the mounting shaft 6 vertically rotates through the movable plate 4 and is fixedly connected to a circular positioning plate 7 located above the movable plate 4, a brake shoe 9 is mounted on the positioning plate 7 and its outer circle is located outside the circle where the positioning plate 7 is located; specifically, a positioning hole is provided on the positioning plate 7, and the connecting hole and the positioning hole on the brake shoe 9 can be connected by a bolt 8, so as to realize the positioning and clamping of the brake shoe 9, and two brake shoes 9 can be mounted on the positioning plate 7, so as to have a relatively higher processing efficiency.

[0024] In the above embodiment, the rotating grinding wheel 2 only rotates relative to the mounting plate 1 without generating relative displacement. The movable plate 4 is driven by the telescopic driver 3 to move the brake shoe 9 away from or close to the rotating grinding wheel 2 to achieve grinding. In the process, the first driving motor 5 drives the brake shoe 9 to rotate so that the outer circle of the brake shoe 9 can contact the rotating grinding wheel 2 to achieve grinding. In this way, the overall structure is relatively simple and the corresponding failure rate is also reduced, which solves the problem that the device structure in the prior art is relatively complex and may lead to a high failure rate and high maintenance cost. Furthermore, a mounting column 10 is also installed on the mounting plate 1, and a pipe 11 is arranged in the mounting column 10 and a nozzle 12 connected to the pipe 11 is also installed on the mounting column 10 (the other end of the pipe 11 can extend to the bottom of the mounting plate 1 for receiving the grinding liquid). The nozzle 12 is aimed at the contact point between the rotating grinding wheel 2 and the brake shoe 9, so as to supply the grinding liquid to the contact point. Since the brake shoe 9 is in the process of self-rotation, the position of the nozzle 12 does not need to be adjusted, and only needs to be aligned.

[0025] like Figure 1-3 As shown, more specifically, a driving shaft 13 perpendicular to the mounting plate 1 is rotatably mounted on the mounting plate 1, and the rotating grinding wheel 2 is fixedly sleeved on the driving shaft 13. The driving shaft 13 is also connected to a second driving motor 14 that drives it to rotate. The second driving motor 14 drives the driving shaft 13 to rotate the rotating grinding wheel 2. Furthermore, a mounting cover 15 that is arranged outside the rotating grinding wheel 2 is fixedly connected to the mounting plate 1, and the mounting cover 15 is open toward one side of the movable plate 4 so that the rotating grinding wheel 2 is partially exposed to smoothly contact the brake shoe 9 for grinding. The second driving motor 14 is mounted on the top surface of the mounting cover 15, and the protective cover provides protection for the rotating grinding wheel 2, and also provides an installation base for the second driving motor 14, so that the second driving motor 14 can be located at a higher place to be protected from the influence of the grinding fluid.

[0026] like Figure 1-3As shown, further, a pair of sliding bars 16 are fixedly connected to the mounting plate 1, and a pair of connecting bars 17 are fixedly connected to the moving plate 4. The two connecting bars 17 are respectively in sliding fit with the two sliding bars 16, so that the moving plate 4 can be slidably arranged relative to the mounting plate 1. The telescopic driver 3 can be a cylinder, an electric push rod, etc., and has a horizontally arranged output end 18. The output end 18 is fixedly connected to the moving plate 4, and can drive the moving plate 4 to reciprocate. More specifically, a U-shaped chute 19 is recessed on the lower end surface of the connecting bar 17, and the sliding bar 16 is slidably connected to the corresponding chute 19, so that the cooperation between the connecting bar 17 and the sliding bar 16 is more stable; more specifically, the first driving motor 5 is located between the two connecting bars 17 and is separated from the mounting plate 1. The first driving motor 5 is located below, which can save space, make the device structure more reasonable, and at the same time, it will not be blocked by the mounting plate 1. Further, a baffle 20 located between the rotating grinding wheel 2 and the first driving motor 5 is also fixedly connected between the two connecting bars 17, and the baffle 20 is separated from the mounting plate 1 and fixedly connected to the moving plate 4. The baffle 20 can prevent the grinding liquid from contacting the first driving motor 5.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
