Screw measuring machine

Abstract

The invention discloses a screw measuring machine which comprises a cast iron workbench, a spindle box is fixedly installed at the upper end of the cast iron workbench, a clamping assembly is rotatably installed on one side of the spindle box, a tip tailstock is fixedly installed at the upper end of the cast iron workbench, a tip is arranged on the tip tailstock, the clamping assembly coincides with the central axis of the tip, a servo motor is fixedly installed on the cast iron workbench, an output shaft of the servo motor is in transmission connection with the clamping assembly, an encoder is fixedly installed on the other side of the spindle box, and a rotating shaft of the encoder is coaxially and fixedly connected with the clamping assembly. Manual measurement is not needed in the whole measurement process, automation is achieved, the measurement efficiency and the measurement accuracy are improved, the radial position and the height of a laser measuring head can be finely adjusted, and therefore the device is wider in measurement range and more convenient to use.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a screw measuring machine. Background technique [0002] The screw is a cylinder with a spiral groove cut on the outer surface or a cone cut with a spiral groove on the conical surface. The screw is an important component in the mechanical field and can be used in various applications such as mechanical connection and mechanical transmission. Screws are mostly used in plastic molding equipment, such as plastic profile extruders, injection molding machines, etc. Screws and barrels are the core components of plastic molding equipment, the part of heating extrusion plasticization, and the core of plastic machinery. Screws are widely used in machining centers, CNC machines, CNC lathes, injection molding machines, wire cutting, grinding machines, milling machines, slow wire, fast wire, PCB drilling machines, engraving machines, engraving and milling machines, s...

AI Technical Summary

Problems solved by technology

After the screw is manufactured, the integrity of the thread and the accuracy of the screw need to be inspected. Only when the screw meets the national standard can it be sold normally and use the geometric parameters of the screw. Within the acceptable range, at present, most of the detection and measurement of screw rods are performed manually, the consistency of measurement is relatively poor, and the accuracy of screw rod measurement is limited, and the degree of automation is not high, resulting in low efficiency

Existing screw detection devices have low detection efficiency for screw accuracy, which can no longer meet the actual needs of the current industry for screw detection and measurement.
