Automatic detection device for ultrasonic welding strength and quality and drawing force of pump housing

Abstract

The invention relates to an automatic detection device for ultrasonic welding strength and quality and drawing force of a pump housing. The automatic detection device comprises a device rack, a product tool, a stepping motor and a screw pair, wherein the device rack is sequentially provided with a rear plate, a vertical plate I and a vertical plate II from left to right; the stepping motor is fixed to the vertical plate I and controls a screw to rotate; two ends of the screw are placed on the two vertical plates respectively; the product tool comprises two tensile tool positioning blocks, a pump cover seat for placement of a water pump cover, a pump body seat for placement of a water pump body, a guide rail fixed between the rear plate and the vertical plate, a sliding block slidably cooperating with the guide rail, a force sensor fixed to a nut and an overload protection device; the pump body seat is fixed to the sliding block; the pump cover seat is arranged between the two tensile tool positioning blocks; one end of the overload protection device is connected with the pump body seat, and the other end thereof is connected with an input end of the force sensor; and the vertical plate II is provided with a proximity switch. The automatic detection device has the advantages of reducing labor costs, improving the drawing force testing accuracy, and automatically completing the product welding quality and strength determination, and is convenient for process control.

Description

technical field [0001] The invention relates to an automatic detection device for the ultrasonic welding strength, quality, and drawing force of a water pump shell, which is suitable for testing the water pump shell with a pulling force ≥ 300N. Background technique [0002] At present, it is found that in the actual use of some water pump products, the pump cover is easy to fall off, that is, the pump cover and the pump body are separated at the welding surface 46 (such as Figure 11 ), such as the 1046745 water pump, urgently needs to be added to the production line to add the production process of the pulling force detection after the pump cover and the pump body are welded. [0003] At present, the known automatic tensile test equipment is suitable for static load, tension, compression, bending, shearing, peeling and other mechanical performance tests on various materials. The operation is complicated, the rhythm is slow, and the cost is high, so it is not suitable for wat...

AI Technical Summary

Problems solved by technology

[0003] At present, the known automatic tensile test equipment is suitable for static load, tension, compression, bending, shearing, peeling and other mechanical performance tests on various materials. The operation is complicated, the rhythm is slow, and the cost is high, so it is not suitable for water pumps. Production line welding strength quality qualification judgment

[0004] As for the manual pulling force testing equipment, the structural accuracy depends on vision, and the power is manual, which is time-consuming and laborious, and the detection speed is slow, which cannot meet the rhythm requirements of the production line, and the labor cost is high.
