Multi-head thread indexing accuracy online detection device

Technical Field

The utility model relates to a detection device for multi-head thread machining indexing accuracy of a main screw of an electric thread press, in particular to an on-line detection device for multi-head thread indexing accuracy.

Background

At present, the machining of the multi-head threads of the main screw rod of the electric screw press cannot realize the on-line detection of the machining indexing errors of the multi-head threads in the machining process, the precision can be controlled as much as possible only by means of equipment precision or the skills of operators, and after the machining is finished, the indexing precision errors are detected by adopting a special measuring device or other machining equipment, so that the on-line machining, detection and adjustment cannot be realized, and the indexing precision of the multi-head threads is improved.

Disclosure of utility model

The utility model aims to provide a multi-head thread indexing accuracy online detection device capable of online detecting the indexing accuracy error of multi-head thread processing, so that the indexing position of the multi-head thread processing can be timely adjusted, and the indexing accuracy of the multi-head thread is improved, so that the problems in the prior art are solved.

The technical scheme of the utility model is as follows: the device comprises a dial indicator, a fixed rod, a sealing cover, a positioning rod, a supporting seat and a supporting rod;

the utility model discloses a sealing device for a solid-state motor, including dead lever slope setting, percentage table swing joint in the bottom of dead lever, sealed lid one end fixed connection in the back of dead lever, the other end fixed connection of sealed lid at the upper surface of supporting seat, the lower surface symmetry of supporting seat set up a pair of bracing piece, the supporting seat on the symmetry set up a pair of locating lever.

Preferably, the sealing cover is in a folding opening shape and is formed into a whole by a horizontal section and an inclined section, the horizontal section is parallel to the upper plane of the supporting seat, and the inclined section is horizontal to the fixing rod.

Preferably, the pair of support rods are symmetrically arranged at two sides of the fixed rod.

Preferably, the positioning rod is vertically arranged on the supporting seat.
