Problems solved by technology

[0002] At present, in the assembly process of parts and products, the tightening operation of bolts and other fasteners and product size detection are mostly completely manual operations, with low automation, high labor intensity, and low production efficiency. Due to the high precision of the detection, there are differences in the test results of different personnel, and the detection efficiency is also low, which affects the judgment of the product qualification rate
Existing detection is carried out by measuring blocks,

Abstract

The invention relates to a machine for detecting the tightening degree and the center height of a screw. The machine comprises a work table (1), a torque calibration device (2), a size calibrating device (3), a product vertical conveying mechanism (4), a control system (5), an online laser measurement device (6), a screw sleeve (7), a beam (8), a display screen (9), a screw tightening device (10), a servo locating device (11), a fixed torque sensor (12), a screw automatic aligning device (13) and position sensors (14). The work table (1) is provided with a product clamp, the fixed torque sensor (12) is arranged at the bottom of the product clamp, and the screw tightening device (10) comprises a servo motor, a speed reducer, a dynamic torque sensor and the screw sleeve (7). The control system (5) comprises an input and output unit, a control unit, an analog-digital conversion unit and a servo driver. The machine has the advantages of being high in automation and production efficiency, capable of automatically detecting product parts, and accurate in tightening torque.

Description

technical field [0001] The invention relates to the technical field of non-contact measurement and screw tightening, in particular to a screw tightening and center height detection machine. Background technique [0002] At present, in the assembly process of parts and products, the tightening operation of bolts and other fasteners and product size detection are mostly completely manual operations, with low automation, high labor intensity, and low production efficiency. Due to the high precision of the detection, there are differences in the test results of different personnel, and the detection efficiency is also low, which affects the judgment of the product qualification rate. Existing detection is carried out by measuring blocks, and the detection result has no data, but a range, poor measurement accuracy and low efficiency; while the torque is controlled entirely by the operator's feeling, the torque value of tightening the screw cannot be precisely controlled; the exis...
