Problems solved by technology

[0003] At present, large-format sanding machines over six feet are being gradually promoted in China. The belt tensioning method uses a tensioning beam and a tensioning cylinder to form a tensioning mechanism. Only two airbags are added at both ends of the tensioning beam to assist tensioning. In order to solve the problem of insufficient rigidity of the tension beam, the correction effect is not ideal

Embodiment Construction

[0022] Such as Figure 1~3 As shown, a belt deviation correction mechanism of a sander includes a coupling seat 1, a bearing housing 2, and a deviation correction cylinder. The end of the tension roller 8 installed on the light machine extends into the connection end of the bearing seat 2, and one side of the bearing seat 2 is extended with a mounting block 4, and the central beam on the sanding machine is provided with a joint end 5, the mounting block 4, the joint end Between 5, a deviation correction cylinder is added.

[0023] According to a preferred embodiment of the present invention, the deviation correction cylinder adopts a double-connected cylinder 3 . Such as figure 1 As shown, one end of the piston rod of the double-connected cylinder 3 and the extended mounting block 4 on the bearing seat 2 are fixed by screws, and the other end of the piston rod is fixed on the joint end set on the central beam of the sander frame. 5 on. In order to make it easier for the u...

Abstract

The invention relates to a sand belt correcting mechanism of a sander, belonging to the technical field of mechanical processing equipment. The sand belt correcting mechanism comprises a connecting base, a bearing base and a correcting cylinder; the tension device of the sander is connected with the connecting base; the tail end of the connecting base is connected with the bearing base, the end of the tension roller arranged on the sander extends into the connecting end of the bearing base, and a piston rod of the correcting cylinder is respectively connected with the central beam of the bearing base and the central beam of the sander. The invention, based on the cooperation of the duplex cylinder and two cylindrical linear tracks, is capable of effectively carrying out correction in realtime even for the big-breadth heavy contact sander beyond 6 feet and can not shorten the service life due to the frequent actions during the correction.

Description

technical field [0001] The invention relates to a deviation-correcting mechanism, in particular to a deviation-correcting mechanism for an abrasive belt of a sander, and belongs to the technical field of mechanical processing equipment. Background technique [0002] The belt tensioning method of the wide-width sanding machine produced in China is: the bearing seats at both ends of the tensioning roller are fixed on the tensioning beam, and a tensioning cylinder piston rod is fixed on the center point of the tensioning beam, and at the same time drives the tensioning beam. Beam and tension roller realize belt tension and relaxation. Therefore, the tensioning cylinder is also the origin of rotation of the belt deflection correcting swing action. At present, the common ways of correcting the deviation of the abrasive belt are: using a single-acting cylinder, which can only realize the deviation correction of the belt in one direction, and the position of the correcting cylinde...
