Description

Workpiece rotating type clamp

Technical Field

The utility model relates to a reservoir leaks and leaks the spare part of examining equipment, especially relates to a work piece rotation type anchor clamps.

Background

The leakage detection equipment for the liquid accumulator is a key equipment for producing liquid accumulator assemblies (including a vapor-liquid separator assembly, a silencer assembly and the like) in the air-conditioning refrigeration industry, and is used for detecting the tightness (leakage) of the liquid accumulator assemblies and the like. The device on the market can be roughly divided into two forms of a rotary turntable and a fixed table type: the rotary turntable equipment is generally provided with 12-20 stations, and each station rotates to enter an upper workpiece area and a lower workpiece area, a soldering flux cleaning water tank, a leakage observation water tank, a rust-proof liquid soaking water tank and the like to circularly work; the stationary table equipment is configured with 2-8 stations and a leak observation sink.

Generally, the working mode of equipment leakage water detection is as follows: the liquid storage device is manually clamped and fixed in the station clamp and the air inlet and the air outlet of the liquid storage device are sealed, the testing system fills about 5MPa of testing gas (nitrogen or compressed air) into the liquid storage device, the up-down lifting device drives the clamp and the liquid storage device to enter the leakage observation water tank, transparent glass is arranged on the front surface and the back surface of the water tank, the existence or nonexistence of bubbles escaping from each welding line of the liquid storage device in water can be manually observed, and whether the liquid storage device to be tested leaks or not is judged. In order to comprehensively and accurately judge whether the detected liquid accumulator leaks, the front side and the back side of a leakage observation water tank are respectively provided with an observer in the conventional production mode so as to avoid missing detection and wrong judgment; in addition, a mirror is arranged on the back of the water tank, so that an observer on the front can see the back of the liquid storage device through reflection of the mirror.

The existing clamps at each station of the equipment generally adopt fixed clamps (as shown in figure 1), each clamp at each station can clamp two liquid reservoirs, the liquid reservoirs are manually clamped, a lower sealing head is firstly arranged on an air outlet pipe orifice of the liquid reservoirs, then a bent pipe is placed into a bent pipe nylon protective seat, and then the quick clamp is pulled down to enable the upper sealing head to be sleeved into the air inlet pipe orifice and locked. The upper sealing head and the lower sealing head both adopt an O-shaped ring self-sealing mode, wherein the upper sealing head is provided with an air inlet and an air outlet for testing air. In general, when the variety of the liquid storage device is replaced, the upper sealing head, the lower sealing head and the bent pipe nylon protection seat need to be replaced correspondingly; the lower seat plate is adjusted to adapt to different heights, and the position of the lower sealing head baffle is adjusted to adapt to different bent pipe lengths.

The prior art has the following disadvantages: first, two observers are required to respectively observe the front and back of the workpiece. Secondly, when the equipment in the form of the rotary turntable works, observers on the back side need to be in the equipment, the working environment of the observers on the back side is very poor due to the narrow internal space and the heated water (the water temperature is about 60 ℃) in the working area, and the observers on the back side are easy to drown due to the closed space, so that managers are difficult to find, and the possibility of missed detection is high. The mode of placing the mirror at the basin back because the mirror is far away from the observer distance of front to the mirror is polluted by the suspended solid in aquatic very easily, and the clearance is also troublesome, and observation effect is not very ideal yet. And fourthly, two persons at one station are difficult to distinguish and are inconvenient to manage.
