Abstract
The utility model discloses a hollow lead screw structure, which is of a hollow structure. One end of the lead screw is provided with an opening, the other end of the lead screw is closed to form a hollow structure where a cavity is arranged; a cooling pipe is arranged in the hollow structure, the outer end of the cooling pipe is an input end, cooling liquid or gas is input through the cooling pipe, and the lead screw is cooled. Liquid or gas is poured into the hollow structure for carrying out cooling, the operating temperature of the lead screw is reduced, the problem of the length increase of the lead screw due to temperature rise of the lead screw because of long-term working of the lead screw is avoided, and processing accuracy and reliability are favorably ensured.
Description
Technical field
The utility model relates to machining, says so exactly to be used for the screw mandrel that machining is used.
Background technology
In machining, use screw mandrel through regular meeting.Leading screw is the very high part of a kind of precision, and it can accurately confirm the stage coordinates position, and will rotatablely move converts rectilinear motion to, and face and also will transmit certain power is so all have very high requirement at aspects such as precision, intensity and wearabilities.
Existing screw mandrel all is a solid construction, and under long-term work, screw mandrel can generate heat elongated, and the length of screw mandrel is increased, thereby causes the precise decreasing of screw mandrel, can make product processing inaccurate, the q&r of influence processing.
Summary of the invention
Therefore, the purpose of the utility model provides a kind of screw structure of hollow, and this structure can be cooled off screw mandrel, can not produce thermal deformation, can work long hours and does not influence the precision of processing.
Another purpose of the utility model provides a kind of screw structure of hollow, and this screw structure simple structure is convenient to realize.
For achieving the above object, the utility model is to realize like this.
A kind of screw structure of hollow is characterized in that said screw mandrel is a hollow structure; One end of described screw mandrel has opening, and other end sealing forms the hollow structure that inside is cavity; And be provided with a cooling tube in the hollow structure, the outer end of cooling tube is an input, through this cooling tube input cooling liquid or gas, screw mandrel is cooled off.Cool off through perfusion fluid or gas in this hollow structure, reduce the operating temperature of screw mandrel, avoid the screw mandrel long-term work to cause the screw mandrel temperature to raise and problem that the screw mandrel length that forms increases, help ensureing the precision and the reliability of processing.
Said cooling tube extend into the bottom of cavity, can screw mandrel being cooled off fully, avoids local cooling, the phenomenon that the part can not get cooling off.
Said cooling tube is the tubular structure of an opening, makes cooling liquid or gas be input to screw mandrel inside from cooling tube, flows out from the slit between cooling tube and the screw mandrel then, forms a cool cycles.
Said cooling tube, its input is exposed to outside the screw mandrel, so that be connected input cooling liquid or gas with other parts.
The outer end of said screw mandrel is equipped with a capping, through the closure screw mandrel, perhaps screw mandrel is connected with other parts, and the bottom of capping has an apopore, through this apopore trickle or gas.
The utility model adopts this structure, can screw mandrel be modified into hollow structure, can cool off screw mandrel effectively; Avoid screw mandrel the phenomenon of being heated and increasing to occur; Make screw mandrel can keep the stable of length, can ensure the precision of processing, thereby improve working (machining) efficiency and reliability.
And the utility model is simple in structure, practical, realizes easily, can be widely used in existing mechanical processing with on the main shaft.
Description of drawings
The structural representation that Fig. 1 implements for the utility model.
Fig. 2 is the partial enlarged drawing of A part shown in Figure 1.
Fig. 3 is the partial enlarged drawing of B part shown in Figure 1.
The specific embodiment
Shown in accompanying drawing, the practical implementation of the utility model is elaborated.
Like Fig. 1, shown in Figure 2, the utility model is embodied as a kind of screw structure of hollow, and the end that this structure mainly includes screw mandrel 7, screw mandrel 7 is installed with motor seat 12, connects motor through the motor seat; The other end then according to the mode of being used to have, is with bearing 4, axle sleeve 3, lock nut 2 and oil sealing 10, is fixed with screw mandrel tailstock 5 outside the bearing 4, and a side of screw mandrel tailstock 5 is equipped with crashproof blob of viscose 6, and crashproof blob of viscose 6 is generally plastic cement, to increase shock-absorbing capacity; Also be with screw mandrel nut 11 on the screw mandrel 7.
One end of screw mandrel 7 has opening, and other end sealing forms the hollow structure that inside is cavity; And be provided with a cooling aluminum pipe 9 (cooling tube is generally metal material and makes, and is convenient to transmit fast heat, cools off) in this hollow structure.In conjunction with shown in Figure 3; Cool off aluminum pipe 9, extend into the bottom of screw mandrel 7 cavitys 15, and the inner terminals 16 that cooling aluminum pipe 9 extend in the screw mandrel 7 (are offered a hole usually for open structure; So that cooling aluminum pipe 9 is connected with screw mandrel 7), can screw mandrel being cooled off fully; Import the penetralia that cold oils can enter into screw mandrel 7 always through cooling aluminum pipe 9, be convenient to screw mandrel is cooled off.
The outermost end of screw mandrel 7 is provided with a capping 1, and capping 1 is placed on the screw mandrel 7, and leaves a tooth hole 13, to connect oil cooling service pipe, screw mandrel 7 is cooled off.The bottom of capping 1 has an apopore 14, and from then on cold oil is discharged in the apopore 14.
The input of cooling aluminum pipe 9 is exposed to outside the screw mandrel 7, and the socket capping 1 then, and cooling aluminum pipe 9 is connected to the inboard in tooth hole 13 by connector 8, so that import cold oil.
During cooling; Through tooth hole 13 input cold oils, cold oil advances along the direction of arrow, enters into cooling aluminum pipe 9 earlier from tooth hole 13; Enter into the cavity 15 of screw mandrel 7 then along cooling aluminum pipe 9; Flow out from the slit between cooling tube and the screw mandrel, flow out through apopore 14 again, form a cool cycles.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
