Gate pipe joints are arranged at two hole ends, and riser pipe joints are arranged at the other two hole ends. The static-pressure guide sleeve inner wear-resistant layer pouring device with the spline guide rail and the spline guide sleeve serving as one portion of a fixture is simple in structure and convenient to operate, processed spline guide rail pairs are flexible in movement and long in service life, precision is easy to guarantee, and the operating requirements of gear shapers of a certain model can be met.
Description
Technical field
The utility model patent relates to a kind of high speed gear shaper hydrostatic slideway design, wearing layer device in particularly a kind of static pressure fairlead cast.
Background technology
In certain type high speed gear shaper main motion, have favorable rigidity, high accuracy, high speed stroke in order to guarantee system, main shaft adopts the hydrostatic slideway technology.But, because machining accuracy is not enough between the spline guideway, cause phenomenons such as main motion is not steady, heating through regular meeting, influence the life-span of guideway.
Summary of the invention
The technical problem that the utility model will solve provides a kind of apparatus for pouring that can improve the fairlead wear-resistant coating of kinematic accuracy between the spline guideway, is specially adapted to high speed gear shaper main shaft hydrostatic slideway structure Design.
The purpose of the utility model is achieved in that
Wearing layer device in a kind of static pressure fairlead cast, it comprises central shaft, the central shaft outside is provided with the spline guide rail; The spline guide rail outside is provided with static pressure spline fairlead, forms the wearing layer cavity between static pressure spline fairlead and the spline guide rail, and the static pressure spline fairlead outside is provided with holding screw; Static pressure spline fairlead two ends are respectively equipped with down positioning disk and last positioning disk, and following positioning disk outer end is provided with terminal pad, and last positioning disk outer end is provided with gate plate; The wearing layer cavity is provided with four intercommunicating pores through the stainless steel tube and the external world; Wherein, two nose ends are provided with the gate pin joint, and two nose ends are provided with the riser pipeline joint in addition.
The profile of tooth inner surface axial of above-mentioned static pressure spline fairlead is processed into the triangle vertical slot, and smallest circle inner surface circumference is processed with screw thread.
Technique effect below the utility model has been obtained:
Spline guide rail of the utility model and spline fairlead are as the part of frock, and be simple in structure, easy to operate, and the spline guideway that processes has move flexible, long service life, and precision is prone to guarantee, can satisfies the instructions for use of certain type gear shapping machine.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the sketch map of the utility model;
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
Shown in Fig. 1-2, wearing layer device in a kind of static pressure fairlead cast, it comprises central shaft 5; The central shaft outside is provided with spline guide rail 3, and the spline guide rail outside is provided with static pressure spline fairlead 4, forms wearing layer cavity 12 between static pressure spline fairlead and the spline guide rail; The static pressure spline fairlead outside is provided with holding screw 11, and static pressure spline fairlead two ends are respectively equipped with down positioning disk 2 and last positioning disk 6, and following positioning disk outer end is provided with terminal pad 1; Last positioning disk outer end is provided with gate plate 7, and the wearing layer cavity is provided with four intercommunicating pores through stainless steel tube 10 with the external world, wherein; Two nose ends are provided with gate pin joint 9, and two nose ends are provided with riser pipeline joint 8 in addition.The profile of tooth inner surface axial of described static pressure spline fairlead is processed into triangle vertical slot M, and smallest circle inner surface circumference is processed with screw thread N, and Fig. 2 is last not to be illustrated, still the position shown in the N in Fig. 2.
Be cast under the normal temperature environment and carry out, with each degreasing of parts and clean with cleaning agent or acetone, releasing agent all need be coated equably in the locating surface position that contacts with coating adhesive of all cast frocks.With spline guide rail 3 and spline fairlead 4 through central shaft 5 and terminal pad 1, down positioning disk 2, go up positioning disk 6, gate plate 7 stationary positioned, the screw on spline guide rail 3 and the spline fairlead 4 in order to be fixedly connected dish 1 and under positioning disk 2.On spline fairlead 4, screw in holding screw 11 slight amount; Again through the cast gate on gate plate 7 and the last positioning disk 6; Gap internal pressure cast mobile performance better polymerization alloy composite materials wear-resistant coating between guide rail and fairlead need spray releasing agent in guide rail surface during cast equably.After treating that filled with composite materials is full of the gap between guide rail and the fairlead, will flow out from top rising head, cast this moment is basic to be accomplished.Wait for certain hour, treat coating adhesive mobile basicly stable after, screw in holding screw to state shown in Figure 1 and get final product.With the fairlead of cast together with frock behind certain environment held certain hour, remove frock, composite is promptly attached to the inner surface of fairlead and become wear-resistant coating.
For guaranteeing that composite can successfully get between spline guide rail and the static pressure spline fairlead; On static pressure spline fairlead cylindrical, radially make screwed hole; And load onto holding screw 11, and communicating with radial screw bore (as shown in fig. 1) axially making plug hole, mould material is injected into bottom by the upper end through pressure pouring and gravity acting in conjunction; Make things convenient for deaeration, avoid forming core; Holding screw 11 can screw in a little when pouring into a mould simultaneously; After the completion to be cast, after cast coating flow condition is basicly stable, screw in holding screw 11 (like state among Fig. 1) again; So just can extrude the little of gas of also being left behind the casting complete, and make institutional framework tightr.
