Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical assembly automation equipment technology, specifically to a torque valve device for tightening valve caps. Background Technology
[0002] In the valve manufacturing industry, the traditional cap tightening process relies heavily on manual operation. The structure of a control valve, as shown in patent publication number CN202597759U, requires assembling various components before tightening the control cap. Manual operation easily leads to inconsistent tightening torque, necessitating optimization of the product assembly process to achieve standardized production. Furthermore, since the product is made of plastic, conventional clamping and limiting mechanisms can damage the product surface. Utility Model Content

[0004] The technical solution adopted by this utility model is as follows: a torsion valve device, including a base, a workpiece fixing position on the base, and a bracket, a lifting drive mechanism and a rotating mechanism located at the driving end of the lifting drive mechanism on the bracket, an elastic telescopic rod at the end of the rotating mechanism, a workpiece fixing component at the end of the elastic telescopic rod, the workpiece fixing component including a pressing block, the lower end face of the pressing block having a frictional force to tighten the cap, and an elastic block inserted into the middle of the pressing block and tightly fitted to the inner wall of the movable insert.
[0005] As one of the preferred solutions for the torque control valve device, the workpiece fixing position is set on the rotating mechanism, and a lifting mechanism is provided directly below the workpiece fixing part. The lifting mechanism is raised synchronously with the lowering mechanism. The driving end of the lifting mechanism is provided with a top rod that contacts the workpiece, and the lower end of the workpiece fixing position is provided with an opening for the top rod to pass through.
[0006] As one of the preferred solutions for the torsion control valve device, the elastic telescopic rod includes a round tube, a slide rod passing through the middle of the round tube, a limiting groove opened on the side of the round tube, a limiting post passing through the slide rod laterally, the limiting post sliding on the slide groove, and a spring being provided at the top of the upper end of the slide rod.
[0007] As one of the preferred solutions for the torque control valve device, the lifting drive mechanism is a cylinder, the cylinder drive end is provided with a fixed plate, the rotating mechanism is fixed on the fixed plate, and the round tube of the elastic telescopic rod is rotatably fixed on the fixed plate.
[0008] As one of the preferred solutions for the torque control valve device, the rotating mechanism is a rotary cylinder, and the workpiece is fixed in two places.
[0009] The advantages of this invention are as follows: it adopts mechanical operation, and the torque is controllable. It uses a workpiece fixing part and a tight-fitting insert for gripping, and uses the principle of the same inner diameter of the pipe to achieve tight-fitting gripping, avoiding complex claw structures and adapting to the shape of workpieces with different outer surfaces; the pressure block and the elastic block cooperate to realize the pre-assembly gripping and assembly function.
