Abstract
The utility model relates to a quick-acting coupling clamping head device tool for trial leakage, pressure testing and pot freon when assemble the refrigeration commodity. The utility model is composed of a quick clamping part, a quick joint part and a quick connecting sheath part. The utility model is characterized in that a spring clamping head and a sealing ring which are in the middle of the quick clamping part have pressure resistance of 45-50 kg. The utility model solves the problems of unable clamping intensively as homemade copper tube form error for import clamping head tool, and lacking negative force when evacuation or lacking pressure when pot the freon, and the utility model avoids the gas leakage when assemble the refrigeration commodity. The utility model raises the pass percent of assembly, reduces the energy consumption and reduces the processing cost.
Description
The utility model relates to the instrument in the refrigeration industry, especially for the equipment tool in refrigeration products such as refrigerator, air-conditioning assembling leak test, pressure testing, perfusion fluorine Lyons etc.
In refrigeration industry, the leak test in the refrigeration product assembling process, pressure testing or perfusion fluorine Lyons all need the joint chuck to connect, and the particularly modern mode of production more needs the rapid pipe joint chuck.Because the fabricating quality of the radiator copper tube of China's refrigerator does not pass a test, and exists form errors such as circularity, ovality all the time, the end face injustice is jagged in the copper tube cutting, and this has just caused the joint chuck to damage, and working life is short, the insufficient clamping force of seal ring.Compression resistance can only reach 20-25Kg, and often requires more than 35Kg, and the phenomenon that leaks air when therefore assembling vacuumizes negative power deficiency, and perfusion fluorine Lyons underpressure does not guarantee the up-to-standard rate of completed knocked down products to cause repair rate big, the energy, labor waste.Insufficient clamping force also can make copper tube can't clip and rebound out and cause danger.
The purpose of this utility model is to overcome deficiency of the prior art and a rapid pipe joint chuck that has form error enough clamping forces, that be not subjected to be pressed from both sides element to influence is provided.
The utility model has the following drawings.

Below in conjunction with accompanying drawing embodiment, the technical solution of the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3, the rapid pipe joint chuck by fast folder portion (2), fast joint part (6), meet cover portion (16) soon and form.Its special way is that the clamping element of the portion of pressing from both sides soon (2) is the spring collet (9) of internal expansion type, the clamping position of this chuck has the groove that communicates with endoporus (20) of the wide b=0.5-0.6 millimeter of 3-5 bar, the slot end of an end is the outer conical surface structure, be complementary with the internal conical surface of double-screw bolt (10), cone angle is α=85 °～90 °, the other end is the filleted corner structure, is complementary with the bull nose of seal ring (3), and fillet radius is R2.5～3 millimeter.In order to guarantee the elasticity of spring collet (9), the material of chuck selects 45 for use
#Steel is through quenching with Subsequent tempering.
When needs carry out leak test, pressure testing or perfusion fluorine Lyons to refrigeration product, must utilize the rapid pipe joint chuck that compressor and refrigeration product are linked up rapidly.At first will be soon folder portion (2), fast joint part (6), connect cover portion (16) three parts soon and be combined into one.With reference to Fig. 2, promote to connect soon the lock sleeve (14) of cover portion (16) to the right, make steel ball (19) slip into omoplate (13) lining of lock sleeve (14), at this moment just fast joint part (6) can be inserted the cover portion (16) that connects soon, the neck (7) that makes steel ball (19) slip into connected body seat (4) obtains the location, the back lock sleeve (14) of loosing one's grip resets left under the effect of spring (18), back-up ring (12) can not skid off lock sleeve (14), connect connecing of cover portion (16) soon Spool assembly (17) is arranged in the block set (15), when fast joint part (6) insertion connects in the cover portion (16) soon, Spool assembly (5) in the fast joint part (6) backs down the Spool assembly (17) that connects soon in the cover portion (16), promptly backs down one-way valve and makes the loop logical.Fast joint part (6) and the scyewed joint of fast folder portion (2) by joint chair (8) and connected body seat (4), so far, three parts quick combined become the unobstructed integral body in loop, can carry out leak test, pressure testing or the perfusion of fluorine Lyons.
When realizing above-mentioned functions, earlier the copper tube of refrigerator is inserted at the bottom of the hole of joint chair (8) of fast folder portion (2), rotation hand wheel (11), handwheel (11) and double-screw bolt (10) side of being tenon structure, there is back-up ring (1) stop bit double-screw bolt (10) end, prevent that handwheel (11) from skidding off, handwheel (11) drives double-screw bolt (10) and double-screw bolt (10) is produced and moves axially inside pressure, cause spring collet (9) radial contraction, clamp copper tube, simultaneously, because the relation of spring collet (9) filleted corner and seal ring (3) bull nose is shunk seal ring (3) radial deformation and is clamped copper tube simultaneously, has filled up copper tube because the gap that the form error on the external diameter causes, copper tube is pushed simultaneously, form compression resistance and can reach 45-50Kg.
Quick-acting coupling clamping head according to the utility model design, collet has enough big clamping force chucking copper tube, sealing ring thickness is big, can with external different tubular and naturally distortion clamp, the danger that therefore can not cause copper tube to rebound out owing to insufficient clamping force during pressure testing, the form error of copper tube still can be in clamped condition up to 0.3 millimeter, and clamping force can reach 45-50Kg, substantially exceed the needs in leak test, pressure testing or perfusion fluorine Lyons, guarantee the qualification rate of refrigeration product assembling.
