Description

[0001] The utility model belongs to the technical field of grounding devices, in particular to a friction disc disassembly tool. Background Art

[0002] For low-floor vehicle grounding devices, the friction disc assembly process is an important control point. The friction disc assembly generally includes a friction disc body, a friction disc base, and a connector, and its matching form is interference fit.

[0003] In view of the criticality and difficulty of the friction disc assembly process, the friction disc cannot be disassembled once it is assembled. At present, bearing pullers are used for disassembly, but the friction disc is made of copper, which is very easy to deform, and the friction disc base is made of aluminum, which is easy to wear. Disassembly directly leads to the scrapping of parts. The friction disc is the core component of the grounding device, and the assembly precision is very high. When encountering parts upgrades and replacements, reassembly after unqualified tests, and later maintenance products, the entire product can only be scrapped, which will cause great waste and cost increase. For the problem that the friction disc assembly cannot be disassembled, a friction disc disassembly solution is designed to solve the existing problem. Utility Model Content

[0007] Furthermore, the longitudinal clamping mechanism includes two groups of pull plate assemblies, which are symmetrically mounted on the inner walls of the left and right vertical plates; the two groups of pull plate assemblies rotate toward each other to form a pull plate circular opening, which is used to clamp and compress the friction disc body.

[0008] Furthermore, each group of the pull plate assembly includes two pull plate rotating arms and a pull plate clamping arm, which are integrally formed in the shape of the letter U. The pull plate rotating arms are rotatably installed on the left vertical plate and the right vertical plate through countersunk bolts and nuts I. A semicircular pull plate opening is opened on the pull plate clamping arm; the two pull plate openings are connected to form a circular pull plate opening.

[0009] Furthermore, the transverse clamping mechanism includes two groups of push plate assemblies and a group of push plate base supports, the push plate base supports are placed between the left vertical plate and the right vertical plate, the two groups of push plate assemblies are symmetrically placed on the outer walls of the left vertical plate and the right vertical plate, the push plate base supports are movably connected to the two groups of push plate assemblies and can move up and down along the left vertical plate and the right vertical plate; the two groups of push plate assemblies rotate toward each other to form a push plate circular opening, the push plate circular opening is used to clamp the friction disk base, the push plate assembly is located above the longitudinal clamping mechanism, and the push plate base supports are located below the longitudinal clamping mechanism; the push plate base supports are forced to move upward to push out the friction disk base.

[0012] Furthermore, the push plate rotating arm is rotatably installed in the movable groove through a bolt and a nut II; the bolt can move laterally in the movable groove; and the bolt is engaged in the engaging groove.

[0013] Furthermore, the two long sides of the bottom support force plate are concave arc surfaces; the concave arc surfaces are used to avoid nut I and the pull plate rotating arm when the bottom support force plate rises; the distance between the two short sides of the bottom support force plate is greater than the width of the left vertical plate and the right vertical plate.
