Abstract
The utility model relates to a saddle structure of a machining center, and the saddle structure comprises a saddle body, the saddle body is characterized in that a central part of the saddle body extends along two sides direction of the central part, so the saddle body is made to form a cross shape, a bottom side of the saddle body is provided with four guide surfaces respectively connected with four guide rails of a top side of a pedestal, wherein two middle guide surfaces are positioned on a bottom of the saddle body central part. The saddle structure of the machining center increases a contact area between the saddle body and the pedestal through prolonging the two guide surfaces of the central part of the saddle body bottom, and improves stability and processing precision in process; when the saddle body moves to an end portion, the saddle body has a smaller deflecting amount, so a workbench mounted on the saddle body is made to have a higher precision; and a motion speed of the saddle body is not affected.
Description
Technical field
The utility model relates to a kind of saddle structure of machining center.
Background technology
Existing machining center comprises base, saddle, workbench, column, spindle box part; Base is the chassis at whole machining process center, is positioned at bottommost; Column is fixedly mounted on a side of base, and it becomes L shaped with the longitudinal section that base constitutes together; Base is provided with guide rail, and saddle is contained on the guide rail of this base.The rectangular shape of existing saddle; Saddle is the same with the guide pass length that base rail engages, and when saddle moved to the end, the beat amount of saddle was bigger; Make the workbench precision that is installed in above installing not high, and then influence stability and the machining accuracy that product adds man-hour.
Summary of the invention
In view of the deficiency of prior art, the purpose of the utility model is to provide a kind of saddle structure that can guarantee the machining center of displacement stability, machining accuracy and movement velocity.
To achieve these goals; The technical scheme of the utility model is: a kind of saddle structure of machining center; Comprise the saddle body; The middle part of said saddle body is respectively extended one section along its two ends makes the saddle body be cross, the bottom side of said saddle body be provided with four respectively with four guide pass that guide rail engages of base top side, wherein in the middle of two guide pass be positioned at the bottom side at saddle body middle part.
Further, the top side of said saddle body be provided with two respectively with two guide rails that guide pass matches of workbench bottom side.
Further, the middle part of said saddle body bottom side is connected with the ball-screw of base top central portion.
Compared with prior art; The utlity model has following advantage: (1) is for other machining centers; The saddle body middle part lengthening of this machining center; Two guide pass that engage with base also prolong wherein, have strengthened the contact area of saddle body and base, have improved the stability and the machining accuracy that add man-hour; (2) when the saddle body moves to the end, the beat amount of saddle body is littler, makes the workbench precision that is installed in above the saddle body higher; (3) saddle body bottom side about two guide pass keep original size, again can increase friction area within reason, do not influence movement velocity.
Description of drawings
Fig. 1 looks sketch map for the master of the utility model embodiment.
Fig. 2 is the elevational schematic view of the utility model embodiment.
Fig. 3 is the schematic perspective view of the utility model embodiment.
Among the figure: 1-saddle body, 11-middle part, two guide pass in the middle of the 12-guide pass, 121-, two guide pass about 122-, 13-guide rail.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
With reference to figure 1 ~ 3; A kind of saddle structure of machining center; Comprise saddle body 1; It is characterized in that: the middle part 11 of said saddle body 1 is respectively extended one section along its two ends makes saddle body 1 be cross, and the bottom side of said saddle body 1 is provided with four guide pass 12 that engage with four guide rails of base top side respectively, and wherein middle two guide pass 121 are positioned at the bottom side at saddle body 1 middle part; Two guide pass 122 length about the length of two guide pass 121 ratio promptly, said saddle body 1 can slide along about the guide rail on the base.
In the present embodiment, the top side of said saddle body 1 is provided with two guide rails 13 that match with two guide pass of workbench bottom side respectively, and said workbench can slide along 13 front and back of the guide rail on the saddle body 1.
In the present embodiment, the middle part 11 of said saddle body 1 bottom side is connected with the ball-screw of base top central portion, and an end of said ball-screw is connected with servomotor through shaft coupling.
The operation principle of the utility model: two guide pass 121 in centre that the saddle structure of this machining center passes through to prolong saddle body 1 bottom side have improved the stability and the machining accuracy that add man-hour to increase the contact area of saddle body 1 and base; When saddle body 1 moved to the end, the beat amount of saddle body 1 was littler, made the workbench precision that is installed in above the saddle body 1 higher; Two guide pass 122 keep original sizes about saddle body 1 bottom side, again can increase friction area within reason, do not influence the movement velocity of saddle body 1.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
Claims (3)
