Description

Technical Field

[0001] The utility model mainly relates to the technical field of valve body terminal detection, and specifically relates to a valve body terminal detection tooling. Background Technique

[0002] The solenoid valve is an industrial device controlled by electricity magnetism. It is a basic automation component used to control fluids and belongs to an actuator. The solenoid valve can cooperate with different circuits to achieve the expected control, and both the control accuracy and flexibility can be ensured. Different solenoid valves play roles in different positions of the control system. The most commonly used ones are check valves, safety valves, direction control valves, etc.

[0003] During the preparation of the valve body of the solenoid valve, it is necessary to install copper wires and terminals on the skeleton. The copper wires are spirally wound around the skeleton, and the ends of the copper wires are welded to the terminals. Subsequently, the shell is injection-molded on the outer wall of the skeleton. Then, the terminals are bent at 90 degrees by a bending device. After bending, the bent part needs to be inserted into the groove and contact the sensor at the bottom of the groove, indicating that it is qualified. And if both terminals can be inserted into the groove, it means that the angles of the two terminals are the same and are in the same plane, meeting the standard. Otherwise, it does not meet the standard. However, for the detection of the valve body terminals of different models of solenoid valves currently, corresponding-sized groove toolings for detection are required, which do not have universality, increase the cost, and when detecting the terminals of different models of solenoid valve products, it is also necessary to disassemble the previous detection tooling on the transmission equipment, which is very inconvenient.

Specifically, the utility model mainly provides a valve body terminal detection tooling to solve the technical problem that the current tooling structure for detecting valve body terminals is relatively simple, similar to a rectangular groove, and cannot detect valve body terminals of different sizes and does not have general applicability as mentioned in the above background technique.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A valve body terminal detection tooling includes a detection mechanism. The detection mechanism includes a shell and a base, and a rectangular opening is provided on the shell. Two groove inserts are movably connected in the rectangular opening. Each groove insert includes an intermediate body with upper and lower openings. The lower side of each intermediate body is connected with a bottom cover by screws. A sensor is arranged in each bottom cover, and a detachable cushion block is arranged on the upper side of each intermediate body.

[0007] Furthermore, clamping blocks are arranged at both sides of the lower surface of each cushion block, and each clamping block is clamped with a clamping groove, and the clamping groove is arranged on the upper side of the intermediate body.

[0008] Further, two strip brackets are arranged on the upper surface of the outer wall of the housing, and the two strip brackets are distributed in parallel, and pads with different heights are also placed on the two strip brackets.

[0009] Further, a left - right - hand double - threaded screw rod is rotatably connected inside the housing. Nut seats are arranged in different thread sections of the left - right - hand double - threaded screw rod, and a mounting bracket is arranged on each nut seat.

[0010] Further, each mounting bracket and the corresponding intermediate body are connected by screws.

[0011] Further, one end of the left - right - hand double - threaded screw rod is provided with an adjustment knob, and the adjustment knob is located on one side of the outer wall of the housing.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By providing the housing, base, left - right - hand double - threaded screw rod, adjustment knob, nut seat, mounting bracket and groove plug - in, the present utility model realizes that during the detection of valve body terminals, the distance between terminals can be adjusted according to actual detection requirements. At the same time, with the cooperation of pads with different heights, the bending lengths of different terminals can be measured, so as to quickly detect whether the bending lengths and angles of terminals of different types of valves are qualified, improve the general applicability, reduce the production cost, reduce the steps of disassembling and replacing the detection tooling in the traditional mode, and improve the work efficiency.
