Abstract
Description
Technical Field
[0001] The utility model belongs to an automobile air conditioner, in particular to an evaporator pressing block helium inspection tool. Background Art
[0002] At present, helium detection is mainly used for leak detection of evaporators, and helium detection mainly requires clamping. Traditional clamping requires the use of an air inlet head, a plug and a fixture. The radial seal between the product and the air inlet head and the plug is sealed by an O-ring and fixed with a fixture to prevent it from falling out. This method requires three parts to be taken during detection, which is inefficient. Summary of the invention
[0003] The utility model aims to provide a helium detection quick clamping tool, which redesigns the helium detection joint in structure, makes the air inlet head plug fixture into an integral whole, and completes the clamping by taking it once.
[0004] To achieve the above purpose, the technical solution of the utility model is:
[0005] The helium inspection quick clamping tool comprises a left clamp, a right clamp and a tooling clamp, and is characterized in that: the left and right clamps have the same structure and are symmetrically designed; the left clamp comprises a pressure plate and a double-headed screw, one of which is distributed above and below, and a spring is sleeved on the double-headed screw, one end of which is fixed to the pressure plate through a thread, and the other end passes through the left clamp jaw, the tooling clamp, and the right clamp jaw, and is locked by a nut; there is a workpiece fixing hole on the tooling clamp, and the other double-headed screws of the left and right clamps are locked and fixed to the tooling clamp and the left and right clamps through the same structure, and two axial holes are opened on the tooling 4.
[0006] There is an extended claw arm at each end of the clamp for clamping the workpiece.
[0007] The advantages of the utility model are as follows: the utility model designs two left and right clamps, and after the workpiece is set on the tooling clamp, it is clamped and fixed by the left and right clamps. In this way, the workpiece can be taken and placed just by pressing the left and right clamps, eliminating the tedious operation of disassembling and assembling multiple parts in the past, effectively solving the problem of low efficiency of multiple clamping tooling during helium inspection of evaporator, greatly improving tooling efficiency and reducing the labor intensity of employees. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 This is a schematic diagram of the use state of the utility model;
[0010] Figure 3 Schematic diagram of the clamping jaw structure. DETAILED DESCRIPTION
[0011] The utility model will be further described below in conjunction with the accompanying drawings.
[0012] See also Figure 1-3 , the two left springs 3 of the utility model are respectively inserted into the two left double-headed screws 1, and one end of the left double-headed screw 1 is threadedly fixed to the left pressure plate 5. The two right springs 9 are respectively inserted into the two right double-headed screws 8, and one end of the right double-headed screw is threadedly fixed to the right pressure plate 10. The two left double-headed screws 1 are successively inserted into the left clamping jaw 2, the tooling 4, and the right clamping jaw 7, and then fastened with the right nut 11. The two right double-headed screws 8 are successively inserted into the right clamping jaw 7, the tooling 4, and the left clamping jaw 2, and are locked with the left nut 6. Two axial holes are opened on the tooling 4, which cooperate with the workpiece 12 to be inspected through the axial holes. There is an extended claw arm at each end of the left and right clamping jaws, which clamps the surroundings of the workpiece 12 to be inspected through the elastic force of the spring, thereby realizing the clamping of the utility model and the workpiece 12 to be inspected.
[0013] Before the test begins, just press the left and right clamps inwards, so that the spring contracts and the clamps are in a loose state. After the workpiece to be tested is matched with the 4-axis hole of the tooling, loosen the left and right clamps. Under the action of the spring, the left and right clamps can hold the workpiece tightly and complete the test operation. After the test is completed, press the left and right clamps to remove the workpiece. The operation is simple and convenient.
