Abstract
The utility model relates to a machining center lathe bed split joint positioning key, which comprises a first lathe bed and a second lathe bed, and is characterized in that a T-shaped key, a first inclined key and a second inclined key are installed in a split joint key groove of the first lathe bed and the second lathe bed, wherein the upper face and the lower face of the convex portion of the T-shaped key are respectively provided with oblique planes, and the contact faces of the first and the second inclined keys with the T-shaped key are respectively provided with oblique planes. As the joints of the T-shaped key with the inclined keys are both provided with the oblique planes of 1:100, after the T-shaped key is installed in the position, the two inclined keys can be directly arrangedin clearances of the T-shaped key and the lathe beds without repairing, thereby realizing the purpose of positioning two split joint lathe beds. Compared with a common flat key, the machining centerlathe bed split joint positioning key reduces the repair plane, overcomes the weaknesses that the common flat key needs to repair in section and has large operation difficulty under the same condition, can satisfy the design requirements of the positioning of the common flat key, has simple repair and convenient installation, and improves the working efficiency.
Description
Technical field
The utility model relates to a kind of machining center bed splicing positioning key, specifically is applicable to when gantry large-scale mobile machining center etc. such as is milled and needed be used by the multistage splicing machine tool, belongs to the frame for movement technical field.
Background technology
Along with the high speed development of China's mechanical industry, the especially development of heavy industry, more and more to the demand of large-scale metalworking equipment such as numerical control gantry mill; Also the technical parameter of equipment is had higher requirement simultaneously.For the such main equipment of numerical control gantry mill, reach long stroke must finish by the splicing lathe bed, and lathe bed is after splicing, and not only needing also needs to position at splicing machine tool place fitting key with the bolt butt joint.
Before the utility model is made, in existing solution, the general employing at splicing machine tool place processing keyway, and the location flat key is installed.But because the effect of factors such as lathe bed processing, splicing can not guarantee that two sections keyways on the lathe bed cooperate by the theory requirement, and just need button different repair surplus repair in two sections lathe beds to become stairstepping by the location flat key of theoretical situation design.The high low head of this keyway on different section lathe beds increased the quantity that the difficulty of key in the repair process also increased repair face, inefficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of designing requirement that can reach the general flat key location is provided, and repair is simple, and is easy for installation, and the machining center bed splicing positioning key that can increase work efficiency.
According to the technical scheme that the utility model provides, a kind of machining center bed splicing positioning key comprises first lathe bed and second lathe bed, and feature is: T type key, the first inclined-plane key and the second inclined-plane key are installed in the splicing keyway of described first lathe bed and second lathe bed.
The projection upper and lower surfaces of described T type key are processed with the inclined-plane respectively.The described first inclined-plane key, the second inclined-plane key and T type key contacts face are processed with the inclined-plane respectively.
Compared with the prior art the utility model has the following advantages:
The utility model is owing to all be processed with 1: 100 inclined-plane at T type key and inclined-plane keyed engagement place, after T type key is in place, need not two inclined-plane keys of repair, can directly the inclined-plane key be inserted the gap between T type key and the lathe bed, can reach the purpose of locating between two sections splicing lathe beds.With the general flat key ratio, repair face of the present utility model reduces, and can overcome general flat key need segmentation repair under the situation in this, the shortcoming that operation easier is big.Can reach the designing requirement of general flat key location, and repair is simple, easy for installation, and can increase work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise a lathe bed 1, T type key 2, the first inclined-plane key 3, the second inclined-plane key 4 and second lathe bed 5.
The utility model adopts T type key 2, the first inclined-plane key 3, the second inclined-plane key 4 to be installed in the splicing keyway of first lathe bed 1 and second lathe bed 5.
The inclined-plane that the utility model adopts the projection upper and lower surfaces of T type key 2 all to process 1: 100, the first inclined-plane key 3, the second inclined-plane key 4 and T type key 2 contact-making surfaces also are processed with 1: 100 inclined-plane.After being installed in first lathe bed 1 after the 2 process repairs of T type key, the first inclined-plane key 3 and the second inclined-plane key 4 are wedged the projection of T type key 2 and the gap between second lathe bed 5 respectively, can reach the effect of location.
Because positioning spline is directly processed by the machining center lathe on first lathe bed 1 and second lathe bed 5, during splicing, the coincidence error of positioning spline is in the small range usually; So only need directly with copper rod the first inclined-plane key 3 and the second inclined-plane key 4 to be knocked in the gap and get final product, the first inclined-plane key 3 and the second inclined-plane key 4 will fill up the gap on the orientation under the effect on inclined-plane automatically, thereby reach the purpose of location.
Self-lock mechanism is learnt through the inclined-plane, when angle of chamfer β satisfies tg β＜u, is placed on the object on the inclined-plane, its quality size with its is subjected to the size of vertical ground direction power all can not make this object relative with inclined-plane generation slip.Check in steel to steel under unlubricated dose situation by mechanical design handbook, confficient of static friction is 0.15.1: 100 angle of chamfer tg β=0.01 is less than 0.15, so after the first inclined- plane key 3 and 4 wedgings of the second inclined-plane key, Macintosh will be in self-locking state, reach positioning action fully.On other direction of relative movement of two sections lathe beds, the utility model positioning key is installed also, just can be reached the purpose of location fully of two sections lathe beds.
