Embodiment 1

[0046] combine figure 1 , a support roller inner hole processing device in this embodiment includes a grinder body 100, a motor box 200, a center frame 300, and a grinding mechanism are arranged on the grinder body 100, and the center frame 300 and the grinding mechanism are all arranged on the grinder body 100 On the guide rail, the grinding mechanism slides along the guide rail to feed the workpiece 400 in the axial direction, and the steady frame 300 slides along the guide rail to adjust the position in time to adapt to workpieces 400 of different lengths and sizes. Specifically, the grinding mechanism in this embodiment includes a motor, a rotating shaft, and a grinding head mounted on the rotating shaft. The motor drives the rotating shaft to rotate, thereby driving the grinding head to finely grind the inner circle of the workpiece 400 .

[0047] In this embodiment, a connection plate 210 is provided on the side of the motor box 200 close to the center frame 300. The con...

Embodiment 2

[0051] combine figure 2 and image 3 , a support roller inner hole processing device of this embodiment, its structure is basically the same as that of Embodiment 1, further: specifically, in this embodiment, two groups of grooves are provided in the flange sleeve 500, and the grooves include the first groove 511 and the second groove 521, the first groove 511 and the second groove 521 are all annular grooves opened along the circumferential direction of the flange sleeve 500, and the two groups of grooves are arranged equidistantly along the length direction of the flange sleeve 500, here The length direction is the axial direction of the flange sleeve 500 .

[0052] Further, in this embodiment, at least two sets of through holes are provided in each set of grooves, the through holes are arranged along the circumference of the flange sleeve 500, and the locking screws pass through each through hole to lock the workpiece 400, specifically, the first recess There are two set...

Embodiment 3

[0058] combine Figure 4 , a support roller inner hole processing device of this embodiment, its structure is basically the same as that of Embodiment 2, the difference is that: in this embodiment, three groups of first through holes 512 are set in the first groove 511, and the second groove Three sets of second through-holes 522 are provided in the groove 521, and the first through-holes 512 and the second through-holes 522 are arranged in a staggered manner. The holes 522 are also equidistantly arranged along the circumferential direction of the groove, and the surface where the locking screw is located is cross-sectioned to obtain a circular cross-section, specifically as Figure 4 As shown, the included angle between each locking screw and the line formed by the center of the circle is 60°.

[0059] Further, combine Figure 5 and Figure 6 , a support roller inner hole processing device of the present embodiment, the center frame 300 includes a base and two sets of supp...

Abstract

The invention discloses a supporting roller inner hole machining device and a machining method thereof, and belongs to the technical field of machining. The supporting roller inner hole machining device comprises a grinding machine body, wherein a motor box and a center frame are arranged on the grinding machine body, a connecting plate is arranged on one side, close to the center frame, of the motor box, a main shaft of the grinding machine body penetrates through a connecting disc to be connected with a flange sleeve, the flange sleeve is used for installing a workpiece, at least two groupsof grooves are formed in the flange sleeve, through holes are formed in the grooves, and locking screws penetrate through the through holes to lock the workpiece. According to the supporting roller inner hole machining device, at least two groups of grooves are formed in the flange sleeve, and the grooves are arranged at intervals and are matched with the locking screws to clamp and lock the workpiece, and the concentricity of an inner hole and an outer circle of a supporting roller is improved; and the inner hole is finely ground by adopting the device, so that the rotation precision of the supporting roller on the inner hole of the grinding machine is ensured.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and more specifically relates to a processing device and a processing method for the inner hole of a support roller. Background technique [0002] Pickling and pickling stretching and bending straightening machine (hereinafter referred to as pickling and pickling stretching and leveling machine) is used to eliminate strip shape defects such as edge wave, medium wave, and buckle, and improve strip flatness. Steel finishing equipment and tension leveler have become one of the important process equipment on the continuous strip production line. The roll box is one of the main components of the tension leveler, which carries the roll system of each working unit of the tension leveler, including support rolls and work rolls. During the straightening process, the force that the strip acts on the work roll acts on the support roll, and in turn the rotation accuracy of the support roll wil...
