Abstract
The utility model relates to an inner cooling screw tap which comprises a screw tap body working part and a screw tap handle which are integrated; the screw tap handle comprises a clamping straight handle and a locating handle; the circle wall of the clamping straight handle is coaxially provided with a cooling groove. The cooling groove is arranged on the clamping straight handle of the screw tap and rotates synchronously with the screw tap; high-pressure inner cooling liquid is ejected from the cooling groove at a high pressure; in the tapping process, the cooling groove can align with the corresponding screw tap and the inside of a processed screw tap hole; high-pressure water columns directly reach the cooling part; the cooling effect is good and the cutting performance is improved. The utility model has a reasonable structure, is simple to be manufactured, is convenient to be used, can improve the inner cooling effect and the service life of a tool bit. The utility model is suitable for the cooling, lubricating, chip discharging and washing in the process of maneuvering tapping on the dead hole or the through hole of a workpiece.
Description
Technical field
The utility model relates to a kind of machine tools, specifically a kind of interior cold screw tap.
Background technology
We know, in mechanical processing industry, internal thread hole etc. are carried out motor-driven tapping operation, need to solve in the tapping process that the screw tap cutting edge is carried out stable continuous is lubricated and cool off this technical task.That is to say that tapping, fraising, spot-facing, high-speed cutting must cool off, otherwise can't process or cause efficient to reduce greatly.Domestic and international many machining centers all have the equipment of cold mechanism in the band, and it is equipped with special-purpose interior cold screw tap, reamer, milling cutter etc., so that carry out cooling operations.These equipment manufacturing cost height, investment are big, these dedicated tools particularly, and the manufacturing technology difficulty is big, and the price height is difficult for production domesticization.And at present, homemade most of screw tap, cutter etc. do not have cooling body, cause the equipment of cold mechanism in these bands to use.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to use, and is interior cold effective, and cutter life, long machine was with interior cold screw tap.
The technical scheme in the invention for solving the above technical problem is: cold screw tap in a kind of, its cone working portion and tap holder by integrative-structure is formed, tap holder comprises clamping staight shank and positioning handle, it is characterized in that: be axially arranged with cooling groove on the clamping staight shank circumferential wall.
Axially split two cooling grooves on the said clamping staight shank of the utility model circumferential wall.
The utility model is owing to be axially arranged with cooling groove at the clamping staight shank, against existing technologies, cooling groove rotates synchronously with screw tap on screw tap clamping staight shank, cooling fluid penetrates from the cooling groove mesohigh in the high pressure, because the suction-operated of high pressure, high speed and screw tap, in tapping process, cooling groove can be aimed in the screw tap hole of corresponding screw tap and processing, water jets under high pressure is joined to go directly and is cooled off the position, jetting stability and continual cooling fluid, good cooling results has been improved cutting ability.The utility model is rational in infrastructure, makes simply, and is easy to use, cold but effect and cutter life in can improving.It is applicable to workpiece blind hole or through hole is carried out the cooling in the motor-driven tapping process, lubricated, chip removal, cleaning etc.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.
1. cone working portions among the figure, 2. clamping staight shank, 3. positioning handle, 4. cooling groove.
The specific embodiment
From Fig. 1, Fig. 2 as can be seen, a kind of in cold screw tap, its cone working portion 1 and tap holder by integrative-structure is formed, tap holder comprises clamping staight shank 2 and positioning handle 3.The structure of cone working portion 1 and positioning handle 3 and effect are the same with existing external cooling screw tap.Characteristics of the present utility model are to be axially arranged with cooling groove 4 on clamping staight shank 2 circumferential wall.
Axially alternate 180 degree are split two cooling grooves 4 on said clamping staight shank 4 circumferential wall of the utility model.
The utility model is owing to be axially arranged with cooling groove at the clamping staight shank, and particularly 180 degree are split two cooling grooves 4.Cooling groove rotates synchronously with screw tap on screw tap clamping staight shank, and the interior cooling fluid of high pressure is penetrated from cooling groove 4 high pressure, because the suction-operated of high pressure, high speed and screw tap, two bursts of water jets under high pressure are joined to go directly together and cooled off positions.In tapping process, cooling groove can be aimed in the screw tap hole of corresponding screw tap and processing, jetting stability and continual cooling fluid, and good cooling results has been improved cutting ability.The utility model is rational in infrastructure, makes simply, and easy to use, cold but effect and cutter life can be brought up to the former external cooling screw tap life-span more than 2 times in can improving, and have overcome the high deficiency of complex structure, price that cold screw tap exists in the import.The utility model is applicable to workpiece blind hole or through hole is carried out the cooling in the motor-driven tapping process, lubricated, chip removal, cleaning etc.
Claims (2)
1. cold screw tap in a kind, its cone working portion and tap holder by integrative-structure is formed, and tap holder comprises clamping staight shank and positioning handle, it is characterized in that: be axially arranged with cooling groove on the clamping staight shank circumferential wall.
2. cold screw tap in according to claim 1 is characterized in that: axially split two cooling grooves on the said clamping staight shank circumferential wall.
