Abstract
The invention relates to a key for splicing and positioning a lathe bed in a machining center, which comprises a first lathe bed and a second lathe bed, and is characterized in that a T-shaped key, afirst flat key and a second flat key are arranged in spliced key grooves of the first lathe bed and the second lathe bed respectively. The T-shaped key, the first flat key and the second flat key arearranged in the spliced key grooves of the first lathe bed and the second lathe bed respectively; and the T-shaped key is arranged in the first lathe bed, and the first flat key and the second flat key are arranged between the T-shaped key and the second lathe bed respectively. A clearance is reserved between a protrusion part of the T-shaped key and the second lathe bed. The key for splicing andpositioning the lathe bed has a simple and reasonable structure, reduces overhauling faces compared with the prior flat key, and can overcome the defect that the prior flat key needs to be overhauledby sections under the condition, thereby causing difficult operation; and the key can reach the design requirements of the prior flat key for positioning, has the advantages of simple overhauling, convenient installation, and labor cost conservation.
Description
Technical field
The present invention relates to a kind of machining center bed splicing positioning key, specifically be applicable to when gantry large-scale mobile machining center etc. such as is milled and needed be used by the multistage splicing machine tool, belong 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.
In prior art, 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 objective of the invention is to overcome above-mentioned weak point, thereby a kind of machining center bed splicing positioning key is provided, can reach the requirement of general flat key location, and repair is simple, easy for installation, and can save labour cost.
According to technical scheme provided by the invention, a kind of machining center bed splicing positioning key comprises T type key, first flat key, second flat key, described T type key, first flat key, second flat key are installed in respectively in the splicing keyway of first lathe bed and second lathe bed, T type key is installed in described first lathe bed, and first flat key and second flat key are installed in respectively between the T type key and second lathe bed.
Be provided with the gap between the projection of described T type key and second lathe bed.
Compared with the prior art the present invention has the following advantages: the present invention is simple and reasonable for structure; With the general flat key ratio, repair face of the present invention 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, saved labour cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, novel machining center bed splicing positioning key comprises T type key 2, first flat key 3, second flat key 4, and is installed in the splicing keyway of first lathe bed 1 and second lathe bed 5.
The present invention adopts T type key 2 to be installed in first lathe bed 1, and first flat key 3 and second flat key 4 are installed in respectively between the projection and second lathe bed 5 of T type key 2.First flat key 3 and second flat key 4 need to distinguish repair first flat key 3 and second flat key 4 and the face that second lathe bed 5 contacts according to the size in gap between the projection of T type key 2 and second lathe bed 5, can reach the effect of location.And T type key 2 is installed in the top of first lathe bed 1, after the lathe metalworking, need not to carry out repair again.So only need reaching the location purpose that design needs after two facet repairs.On other direction of relative movement of two sections lathe beds, positioning key of the present invention is installed also, just can be reached the purpose of location fully of two sections lathe beds.
