Abstract
The utility model belongs to the technical field of vacuum machineries, and particularly relates to a moving mechanism for a workpiece in a vacuum chamber. The moving mechanism comprises a vacuum box body, wherein vertical guide rods are arranged inside the vacuum box body; sliding bearings are arranged on the guide rods; the sliding bearings are connected with workpiece holders, so as to guarantee the holders to slide vertically on the guide rods; and meanwhile, screw rods are mounted at middle parts of the holders to adjust positions the holders. As for a current vacuum box in the state of vacuum, under the action of the external atmospheric pressure, an upper cover can deform slightly, so as to cause the guide rods and the sliding bearings to be mutually stuck, and not able to move relatively. According to the scheme, an end face of the upper cover inside the box body is connected with a reinforcing plate connected with the guide rods, so that the reinforcing plate is utilized to be connected with the guide rods to avoid the situation that the holders can not move vertically caused by the deformation of the upper cover of the box body.
Description
Technical field
The utility model belongs to the vacuum machine technical field, especially relates to workpiece travel mechanism in a kind of vacuum chamber.
Background technology
In the existing structure, levy workpiece movement in the vacuum chamber of sealing, at first to carry out application of vacuum to large-area workpiece, workpiece will keep level, and by the screw mandrel transmission, make it do small movements up and down. former design is on four angles of box type vacuum chamber loam cake, and four vertical guide posts are installed respectively, be equipped with at work piece holder and can make its sliding bearing that moves up and down along guide post, the anchor clamps center is equipped with screw mandrel.Operating position: when not vacuumizing, anchor clamps can move up and down under screw mandrel drives neatly.But under vacuum state, the screw mandrel transmission is very painstaking, even can not transmission.Failure cause: under vacuum state, because the effect of external pressure, micro-strain will take place in loam cake, causes between guide post and sliding bearing mutually not card, consequently can not relative motion.
The utility model content
The utility model can provide workpiece travel mechanism in a kind of not easily broken vacuum chamber.
In order to solve the problems of the technologies described above, provide following technical scheme: workpiece travel mechanism in the vacuum chamber, comprise vacuum chamber, box house is provided with vertical guide post, guide post is provided with sliding bearing, and sliding bearing connects work piece holder, and the middle part of anchor clamps is equipped with screw mandrel, the loam cake end face of described box house connects stiffener, and stiffener connects guide post.
Adopt above-mentioned technical scheme, in the utility model, the inside of vacuum chamber is provided with vertical guide post, guide post is provided with sliding bearing, sliding bearing connects work piece holder, so just can guarantee that anchor clamps slide up and down at guide post, simultaneously the middle part of anchor clamps is equipped with screw mandrel, position that can alignment jig.Existing vacuum chamber is under vacuum state, because the effect of external pressure, micro-strain will take place loam cake, causes between guide post and sliding bearing mutually not card, consequently can not relative motion.In the utility model scheme, with the loam cake end face connection stiffener of box house, stiffener connects guide post, utilizes stiffener to connect guide post like this, avoids the loam cake of casing to deform, and causes anchor clamps not move up and down.
Further, described stiffener is rectangle, and guide post is distributed in four edges and corners of stiffener respectively, convenient processing, and the symmetrical configuration of vacuum chamber inside is stressed even simultaneously.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of workpiece travel mechanism in the utility model vacuum chamber.
The specific embodiment
As shown in Figure 1: workpiece travel mechanism in the vacuum chamber, comprise vacuum chamber 1, casing 1 inside is provided with vertical guide post 2, guide post 2 is provided with sliding bearing 3, and sliding bearing 3 connects work piece holder 4, and the middle part of anchor clamps 4 is equipped with screw mandrel, loam cake 6 end faces of described casing 1 inside connect stiffener 7, stiffener 7 connects guide post 2, and stiffener 7 is rectangle, and guide post 2 is distributed in four edges and corners of stiffener 7 respectively.
In the present embodiment, the inside of vacuum chamber 1 is provided with vertical guide post 2, and guide post 2 is provided with sliding bearing 3, sliding bearing 3 connects work piece holder 4, so just can guarantee that anchor clamps 4 slide up and down at guide post 2, simultaneously the middle part of anchor clamps 4 is equipped with screw mandrel, position that can alignment jig 4.Existing vacuum chamber 1 is under vacuum state, because the effect of external pressure, micro-strain will take place loam cake 6, causes 3 on guide post 2 and sliding bearing not other card mutually, consequently can not relative motion.In the utility model scheme, loam cake 6 end faces of casing 1 inside are connected stiffener 7, stiffener 7 connects guide post 2, utilizes stiffener 7 to connect guide post 2 like this, avoids the loam cake 6 of casing 1 to deform, cause anchor clamps 4 not move up and down, stiffener 7 is rectangle, and guide post 2 is distributed in four edges and corners of stiffener 7 respectively, convenient processing, the symmetrical configuration of vacuum chamber 1 inside is stressed even simultaneously.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; should be considered as protection domain of the present utility model, these can not influence effect and practical applicability that the utility model is implemented yet.
Claims (2)
