Description
Technical field
The present invention relates to field of machining, specifically is a kind ofly to be applicable to that being used in the various automobile cooling systems detect the bubble-tight anchor clamps of cooling tube.
Background technology
Automobile is generally all used water cooling, mainly is the normal working temperature that guarantees engine, to prevent engine overheat.Usually the cooling tube in the automobile is stainless-steel tube, is fitted together by many pipes, and is located by web joint.Therefore in practical operation, the workman can detect the impermeability of the cooling tube after the assembling, so can use a kind of anchor clamps, detects with convenient.This existing anchor clamps that are used to detect gas tightness of automobile cooling pipe; It comprises two sealing shrouds, admission piece, and admission piece is located on one of them sealing shroud, overlaps upper sleeve gasket to the cooling tube two ends respectively like this; Tighten the screw rod on the sealing shroud; Whether in admission piece, feed gas then, then put into water with the whole parts of handgrip, detecting the cooling tube weld has gas leakage.But this anchor clamps exist following shortcoming:
1. existing detection is to single cooling tube, and promptly the workman is that one one ground detects the bubble-tight of cooling tube, and the upset of whole parts is also inconvenient, greatly increases working strength of workers, reduces production efficiency simultaneously.
2. because the screw rod on the two ends hand-tight make-up sealing shroud of cooling tube, so the clamping force at two ends and not enough, the sealing of itself is all very poor, and the strength of hand and unstable.
3. existing detection is to put into water with artificial both hands to check that hand will be immersed in the water for a long time when the workman operated, and was unfavorable for the healthy of human body.
Summary of the invention
Technical matters to be solved by this invention is, a kind of gas tightness of automobile cooling pipe anchor clamps are provided, and it can greatly be increased work efficiency, reduce labor strength, guarantee the sealing and the stability of anchor clamps, can also avoid influencing simultaneously the healthy of workman.
For solving the problems of the technologies described above; A kind of anchor clamps that are used to detect gas tightness of automobile cooling pipe provided by the invention; Comprise the air-breather that is provided with valve; Described air-breather links to each other with source of the gas, and it also comprises water tank, left rotation and right rotation axle, fulcrum arrangement, clamp device, and described left rotation and right rotation axle is rotatably connected respectively in the right ends of fulcrum arrangement; Described clamp device one end is connected with left-handed rotating shaft through coupling shaft I, and the other end is connected with dextral shaft through coupling shaft II; Described valve is connected with clamp device; Described clamp device; Comprise fixed head, left and right sides rubber blanket, suppress plate, be fixed with air cylinder fixed plate, pull bar, left register pin and the right register pin of cylinder; Described fixed head is connected with left-handed rotating shaft through coupling shaft I; Left side register pin is a tight fit on the fixed head, and left rubber blanket is connected with fixed head through left register pin; Right register pin is a tight fit in to be suppressed on the plate, right rubber blanket through right register pin with suppress plate and be connected; Suppress plate and be connected with the interior piston rod of cylinder, the other end of cylinder is connected with dextral shaft through coupling shaft II; Fixed head is connected through pull bar with air cylinder fixed plate; Described valve is connected with clamp device, is meant that described suppressing is connected with valve on the plate, and described right register pin is provided with the pore that communicates with valve.
After adopting above structure, compared with prior art, the present invention has following advantage:
1. adorn several groups of cooling tubes because this anchor clamps are can be disposable more, carry out impermeability simultaneously and detect, and the upset of whole clamp device also undertaken by turning axle, therefore greatly reduce working strength of workers, improved work efficiency.
2. the two ends of cooling tube are clamped by clamp device, so the clamping force at cooling tube two ends is very stable, and sealing is also fine.
3. because these anchor clamps do not have in the entry one group one group ground upset of cooling tube through turning axle, accept bubble-tight detection, workman's hand also need not be immersed in the water like this, has therefore avoided jeopardizing the healthy of human body.
Be embedded with the cooling tube backing plate on the described fixed head, be fixed with the cooling tube cushion block that at least one and cooling tube are close on the described cooling tube backing plate.After adopting this structure, make the cooling tube assembly, make the cooling tube assembly can not be created in the phenomenon of center section bending, two gas leakage, thereby guarantee sealing more in the supported effect of center section.
