Embodiment Construction
[0014] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0015] Such as figure 1 , figure 2 , image 3 As shown, the present invention includes a tie rod 11, a detection seat mounting block 2, a pressure detection valve and three identical positioning detection mechanisms. The tie rod 11 is axially hollow, and the tie rod 11 is accommodated in the axial center of the machine tool chuck body 1. In the hole, the detection seat mounting block 2 is fixedly installed on the front end surface of the chuck body 1 and connected with the front end of the pull rod 11. Three positioning detection mechanisms are installed on the detection seat installation block 2 at intervals along the circumferential direction; each positioning detection mechanism It includes a detection seat 9, a positioning column 4 and a detection mandrel 5. The detection seat 9 is installed on the detection seat mounting block 2. The dete...

The invention discloses a machine tool chuck clamping detection device, and belongs to a machine tool chuck part. When a workpiece is not clamped in place, the machining precision is affected. The device comprises a hollow pull rod, a detection seat mounting block, a pressure detection valve and three same positioning detection mechanisms, wherein the pull rod is connected with the detection seat mounting block arranged at the front end face of a chuck body, and the three same positioning detection mechanisms are arranged on the detection seat mounting block at intervals along the circumference; each positioning detection mechanism comprises a positioning column, a detection ejector rod and a detection seat arranged on the detection seat mounting block, wherein the rear section of the positioning column is arranged in the groove cavity of the detection seat, the hollow cavity of the positioning column and the groove cavity form a piston cavity, the front section of the detection ejector rod is in zero clearance fit with the cavity wall of the positioning column, the bottom of the groove cavity of the detection seat is provided with an axial through hole and a lateral through hole, and the rear section of the detection ejector rod is provided with a piston cover for covering the axial through hole; the cavity of the pull rod, the axial through hole and an air passage in the detection seat mounting block are connected to form an air path; and the rear end of the pull rod is connected with the pressure detection valve, and workpiece clamping detection is realized by detecting the pressure change of air.
Description
Technical field [0001] The invention belongs to a machine tool chuck component device, and is particularly related to a machine tool chuck clamping detection device. Background technique [0002] The chuck is a component used to clamp the workpiece during lathe processing. When the chuck clamps the workpiece, especially the disc type workpiece, it is sometimes unclear whether the workpiece is clamped in place. If the workpiece is not clamped in place, the processed parts may not meet the processing requirements. For this reason, it is necessary to install a workpiece clamping detection device in the chuck component to detect whether the workpiece is clamped in place. Summary of the invention [0003] The purpose of the present invention is to provide a machine tool chuck clamping detection device capable of detecting the clamping state of a workpiece, so as to detect whether the workpiece is clamped in place. [0004] To this end, the present invention adopts the following techni...
