Description

Technical Field

[0001] The utility model relates to a go / no-go gauge detection device. Background Art

[0002] The go / no-go gauge is a collection of gauges. As a measurement standard, it is used to test large quantities of products. However, in the actual production process, most products are measured manually using the go / no-go gauge, which is time-consuming and labor-intensive, with low testing efficiency, and cannot meet the needs of large-scale product testing, and does not meet the current mechanized and automated production needs.

[0003] Subsequently, an automatic detection device for outer diameter go / no-go gauges (CN112033259A) appeared on the market, which includes a driving mechanism, a feeding mechanism and an actuator. The driving mechanism is connected and cooperated with a linear mechanism. The linear mechanism is provided with an outer diameter go / no-go gauge. The feeding mechanism is provided with a workpiece to be measured. The feeding mechanism transports the workpiece to be measured to the outer diameter go / no-go gauge end of the actuator for detection.

[0004] However, this type of automatic detection device can only be applied to the detection of one type of bolts. When it is necessary to detect bolts of different types, the entire device needs to be replaced. Utility Model Content

[0010] By adopting the above-mentioned technical solution, the present application has a simple structure. The control unit controls the motor to apply different critical forces according to different types of bolts, and then uses the sensor to feedback the instantaneous torque of the motor. At the same time, for different types of bolts, only the through gauge needs to be replaced without disassembling the entire equipment.

A connecting bracket 212 extends from one side of the motor bracket 21. The bearing bracket 22 is connected to the bottom of the motor bracket 21, and a hollow bearing lower hole is provided in the bearing bracket 22, and the bearing lower hole and the bearing upper hole 211 are located on the same axis. The through gauge transverse plate 23 is connected to the connecting bracket 212, and a waist-shaped fixing hole is provided on the through gauge transverse plate 23 for connection with an external detection position. The bracket structure 2 suspends the entire through gauge detection device.

A bearing connection seat 41 is provided at the bottom of the wire sweep spline shaft 4. The bearing connection seat 41 is used to connect the through gauge 5.

[0022] In order to adapt to different through gauges, the present application respectively sets the same connecting shaft 51 matching the bearing connection seat 41 at the top of each type of through gauge 5.
