Roller base plate fixing structure of the edging machine

Abstract

A roller base plate fixing structure for a base of an edging machine is provided. The structure is mounted on the base of the edging machine and includes a roller base plate fixed to the base and multiple pins. These pins are spaced apart to fix the roller base plate to the base, and an interference fit is formed between the pins, the roller base plate, and the base. This prevents weld fatigue damage between the roller base plate and the base when the rollers of the sliding bearing mechanism of the edging machine repeatedly move back and forth on the roller base plate of the base, ensuring that the roller base plate is securely fixed to the base.

Claims

1. A roller base plate fixing structure for a base of an edging machine, which is disposed on a base of an edging machine and includes a roller base plate fixed on the base and a plurality of pins, wherein the plurality of pins are arranged at intervals to fix the roller base plate on the base, and the pins form an interference fit with the roller base plate and the base.

2. The roller base plate fixing structure of the base of the edging machine as described in claim 1, wherein, At least one wear-resistant plate is secured to the roller base plate with a plurality of bolts. The roller base plate has a side portion that extends out of opposite sides of the wear-resistant plate. The plurality of pins are distributed and pass through the side portion of the roller base plate on opposite sides.

3. The roller base plate fixing structure of the edging mill base as described in claim 1 or 2, wherein, The roller base plate is provided with a plurality of through pin holes, and the base is provided with a fixing pin hole corresponding to the position of each pin hole. Each pin is fixed in the pin hole of the roller base plate and the fixing pin hole of the base at the corresponding position, and the top of the pin is recessed in the pin hole.

4. The roller base plate fixing structure of the edging mill base as described in claim 3, wherein, The fixing pin hole is a blind hole that does not penetrate the base. The top of the pin is lower than the top surface of the roller base plate by a gap. The gap between the tops of the pins in the pin hole of the roller base plate is filled with colloid.

5. The roller base plate fixing structure of the edging mill base as described in claim 3, wherein, Each of the pins has a vent hole extending from the bottom end of the pin to the top end of the pin.

6. The roller base plate fixing structure of the base of the edging machine as described in claim 5, wherein, The vent hole includes a small section located at the bottom and a large section located at the top and connected to the small section.
