Abstract
The utility model relates to a spliced positioning flat key, which comprises a first oblique surface positioning key, a second oblique surface positioning key, a positioning block, a first screw and a second screw, wherein the first oblique surface positioning key and the second oblique surface positioning key are arranged in spliced key slots of a first component and a second component respectively; the matching surfaces of the first oblique surface positioning key and the second oblique surface positioning key are provided with an oblique surface respectively; the matching surfaces of the first oblique surface positioning key as well as the second oblique surface positioning key and the key slots in the first component and the second component are provided steps; and the positioning block is tightly connected with the first component through the first screw and the second screw. Compared with an ordinary flat key, the spliced positioning flat key has the advantages that two parts of the flat key are provided with the oblique surfaces, and the flat key is tightly jointed with a key slot on a large-sized component through oblique surface force, so that the positioning effect is ensured; and meanwhile, the spliced positioning flat key is convenient to detach, and has contribution to repeated adjustment of equipment.
Description
Technical field
The utility model relates to a kind of location flat key, and flat key is located in especially a kind of large component splicing, uses when being applicable to the large parts plane positioning, belongs to the mechanical structure technical field.
Background technique
Along with the high speed development of China's mechanical industry, the especially development of heavy industry, more and more to the demand of Big Gold process equipment; Also the technical parameter of equipment is had higher requirement simultaneously.For some large-sized numerical control equipment, guarantee the machining accuracy of product complete machine, need not only to rely on that closed-loop is controlled, the contour performance parts of precision drive parts, also require simultaneously junction plane location between the medium-and-large-sized parts of equipment accurately, stable.
Between common large component, the location of junction plane adopts flat key to locate, and the method need to be at large parts junction plane place's processing keyway.Impact due to factors such as the large component junction plane is processed, splicings, keyway on the large component that can not guarantee to combine coordinates by the theory requirement, and therefore locating flat key just need to become stairstepping by flat key different repair surplus repair in two-part large component.The high low head of this keyway in different large components makes single flat key need to carry out the repair of 4 faces, increased the difficulty of key in the repair process, makes working efficiency be difficult to improve.Moreover, flat key is completed when assembling in repair, must with the keyway interference fit, this just makes the dismounting of flat key comparatively require great effort, and particularly can cause the flat key deformation of joint surface after being dismounted for multiple times, causes flat key to lose efficacy.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of splicing to locate flat key, and the keyway on this location bond energy and large component fits tightly, and guarantees locating effect; Simultaneously for convenience detach, be conducive to the repeatedly adjustment of equipment.
The technological scheme that provides according to the utility model, splicing location flat key comprises the first contour localization key, the second contour localization key, positioning block, the first screw and the second screw, and described the first contour localization key, the second contour localization key are arranged on respectively in the splicing keyway of first component and second component; The fitting surface of described the first contour localization key and the second contour localization key is processed with respectively the inclined-plane, and in the first contour localization key, the second contour localization key and first component, second component, the fitting surface of keyway is provided with step; Described positioning block is fastenedly connected by the first screw and the second screw and first component.
As further improvement of the utility model, described the first screw end face and the first contour localization key contacts.
As further improvement of the utility model, described the second screw is connected with the second contour localization key upper screwed hole by the through hole on positioning block.
As further improvement of the utility model, described first component is provided with keyway; Described second component is provided with keyway.
Compared with the prior art the utility model has the following advantages: the utility model is simple and reasonable for structure; Compare with parallel key, by the inclined design on flat key two-part, and by inclined-plane power, the keyway on flat key and large component is fitted tightly, guarantee locating effect; Simultaneously for convenience detach, be conducive to the repeatedly adjustment of equipment.

Embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As Fig. 1～shown in Figure 2, comprise the first contour localization key 3, the second contour localization key 4, positioning block 5, the first screw 6 and the second screw 7.
Described the first contour localization key 3, the second contour localization key 4 are arranged on respectively in the splicing keyway of the first large component 1 and the second large component 2.Wherein the fitting surface of the first contour localization key 3 and the second contour localization key 4 is processed with the inclined-plane, and in the first contour localization key 3, the second contour localization key 4 and the first large component 1, the second large component 2, the fitting surface of keyway is made as stepped form, and according to the deviation repair step height drop of keyway in the first large component 1, the second large component 2.Described positioning block 5 is connected with the first large component 1 by screw.Be arranged on that in positioning block 5, the first screw 6 end faces on tapped hole contact with the first contour localization key 3, and by screw thread power, the first contour localization key 3 pushed away positioning block 5; And the second screw 7 is connected with the second contour localization key 4 upper screwed holes by the through hole on positioning block 5, and by screw thread power with the second contour localization key 4 positioning block 5 that furthers.And owing to coordinating by the inclined-plane between the first contour localization key 3 and the second contour localization key 4, under the screw thread power effect of the first screw 6 and the second screw 7, inclined-plane component closely cooperates the keyway on the first contour localization key 3 and the second contour localization key 4 and the first large component 1 and the second large component 2, completes thus the location of large component junction plane.
Working procedure of the present utility model and working principle
The utility model is when repair, and contour localization key 3, contour localization key 4 all only need according to recording the keyway step vertical deviation size of installing, and two repair faces are carried out repair, can complete repair, and the repair difficulty is low.And after repeatedly removing and installing positioning key of the present invention, even the flat key junction plane due to stressed rear generation distortion, also passes through the inclined-plane elimination between contour localization key 3 and contour localization key 4, after guaranteeing thus repeatedly to install, effective installation of the utility model positioning key.
