Technical Field

The invention belongs to the technical field of machining, and particularly relates to a reverse-table type roller correcting device.

Background

At present, with the development of machining technology, the space size of large-scale parts which can be machined is larger and larger, and the achievable machining precision is higher and higher, so that higher and higher requirements are also put forward on the measurement technology. In the large-diameter measurement method, the roller method has the advantages of simple structure, convenient operation and the like, but the measurement is difficult to reach the level of high accuracy due to the influences of slippage, pressure deformation of the roller and temperature errors. Therefore, in order to improve the measurement accuracy of the roller method, correcting the measurement error caused by the compression deformation of the roller becomes one of the key technologies which need to be researched;

and the problems of grinding burn and vibration lines which are easy to appear in the traditional single-point correction, no sharp grinding blade and the like are solved.

Disclosure of Invention

In view of the problems in the prior art, the invention aims to provide a reverse-table roller correction device.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a reverse-table roller correcting device, includes the base, be equipped with the fixed frame of symmetric distribution on the base, be equipped with the correction arm in the fixed frame, correction arm both ends are through pivot and fixed frame swing joint, fixed frame upper end all is equipped with the fixed block, be equipped with the hydraulic cylinder of inversion between the fixed block, the flexible end in bottom of hydraulic cylinder is equipped with the assorted piston rod, the piston rod bottom is rotated through connecting axle and correction arm one end and is connected, the other end of correction arm is equipped with the dead lever, the dead lever extends the end and is equipped with the emery wheel excircle trimming piece parallel with the dead lever, and dead lever one side is equipped with the emery wheel terminal surface trimming piece.

Preferably, the correcting arm positioned on one side of the fixing rod is provided with a limiting bolt.

Preferably, the bottom of the correction arm positioned on one side of the piston rod is arc-shaped, an arc-shaped groove matched with the arc-shaped bottom of the correction arm is formed in the base, and the arc-shaped bottom of the correction arm can rotate around the rotating shaft in the arc-shaped groove.

Furthermore, the limit bolt passes through the correction arm in a threaded connection mode, a connecting bolt capable of vertically moving up and down is arranged at the bottom of the limit bolt, an L-shaped adjusting groove is formed in the base and located at the bottom of the connecting bolt, the bottom of the connecting bolt is connected with an inlet at the upper end of the L-shaped adjusting groove in a threaded connection mode, an outlet of the L-shaped adjusting groove is communicated with the arc-shaped groove, a movable connecting rod is arranged at the outlet of the L-shaped adjusting groove, a movable limiting block is arranged in the arc-shaped groove and fixedly connected with the connecting rod, a transmission rod is arranged in the L-shaped adjusting groove, and two ends of the transmission rod are respectively connected with the corresponding end portions of the connecting bolt and the connecting rod in.

Furthermore, a clamping groove is formed in the bottom of the limiting bolt, clamping plates which are clamped mutually and can move up and down are arranged in the clamping groove, a fixedly connected adjusting rod is arranged at the upper end of the connecting bolt, and the upper end of the adjusting rod movably penetrates through the bottom of the clamping groove and is fixedly connected with the clamping plates.

Furthermore, first racks which are uniformly distributed are arranged on the arc-shaped bottom of the correction arm, and second racks which are uniformly distributed and meshed with the first racks are arranged on the limiting block.

Compared with the prior art, the invention has the following technical effects:

the invention realizes the falling and lifting actions of the trimming arm by using a connecting rod driving mechanism consisting of a piston rod in a hydraulic cylinder and the trimming arm. Because the roller is mainly trimmed by edges, not by surfaces, the roller has a certain inclination angle during trimming. The device once clamping can accomplish the plastic and the dressing of emery wheel, has solved the grinding burn and the line of shaking that traditional single-point correction appears to and the not sharp scheduling problem of grinding cutting edge, improved emery wheel correction precision and finishing efficiency.
