The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
As shown in Figure 1 to Figure 3, for horizontal kneeand-column type milling machine of the present utility model and for the overarm of horizontal kneeand-column type milling machine, move and retaining mechanism, described horizontal kneeand-column type milling machine comprises base 10, lathe bed 11, lifting platform 40, workbench 50 and overarm 12.Lathe bed 11 and lifting platform 40 are fixed on base 10; Workbench 50 is located on lifting platform 40, workbench 50 place work pieces; The top of lathe bed 11 arranges overarm 12; Described overarm, and is fixed on overarm 12 on lathe bed 11 by retaining mechanism by guide rails assembling on lathe bed 11; Described overarm 12 and the top of lathe bed 11 are that the dovetail guide being slidably matched coordinates.
In order to solve the problem of prior art existence and to overcome its defect, realize meeting under the prerequisite of overarm locking property, improve the goal of the invention of the convenience operating, the technical scheme that the utility model is taked is:
As shown in Figure 3, horizontal kneeand-column type milling machine of the present utility model, described milling machine arranges slippage driving mechanism and overarm retaining mechanism 20; Described slippage driving mechanism is provided with overarm gear shaft 22, and described overarm gear shaft 22 is located on lathe bed 11; Described overarm 12 is provided with the tooth bar with the gear engagement in gear shaft 22 of hanging oneself from a beam; Described overarm retaining mechanism 20 is provided with overarm locking teeth wheel shaft 23; Between the guide rail mating surface of described lathe bed 11, overarm 12, be provided with and carve piece 21, the described piece 21 of carving is provided with the tooth bar meshing with the gear of hanging oneself from a beam on locking teeth wheel shaft 23.
Adopt technique scheme, under the prerequisite of satisfied overarm locking property, improve operation convenience.By compact structure, can be by overarm locking easily, can realize again slides simultaneously drives; The utility model is simple in structure, dependable performance, and processing and manufacturing and assembling simple.
Described overarm locking teeth wheel shaft 23, is formed the rotation of sliding and coordinates by its inner hole sleeve in described overarm gear shaft 22; Gear in described overarm gear shaft 22 is outside the inner face of overarm locking teeth wheel shaft 23, and its external diameter is greater than the aperture of overarm locking teeth wheel shaft 23.
The effect of this structure is the axial float of restriction overarm gear shaft 22.
Described overarm locking teeth wheel shaft 23 and overarm gear shaft 22 are for being rotatably assorted.
Owing to having adopted the structure of overarm locking teeth wheel shaft 23 with the coaxial package of overarm gear shaft 22, on the one hand, make structure more compact, on the other hand, make operation more simple and convenient.
Described overarm gear shaft 22 is stretched out the end of lathe bed 11, is provided with the moving handle seat 24 being fixedly connected with it, and described moving handle seat 24 is provided with the moving handle bar 25 being fixedly connected with it.
The end that described overarm locking teeth wheel shaft 23 stretches out lathe bed 11, is provided with set lever bar 26.
Moving handle seat 24 is fixed in overarm gear shaft 22 by pin 32, and moving handle bar 25 is arranged on moving handle seat 24, and fixing with pin 31.
Described overarm locking teeth wheel shaft 23 is provided with the annular groove of axial location, at overarm locking teeth wheel shaft 23, rotates on cylindrical and is provided with and limits its axially movable ring-shaped groove; On lathe bed 11, establish the axial retention pin 33 being fixedly connected with it, described axial retention pin 33 ends snap in described annular groove.
Said structure, has limited the axial float of overarm locking teeth wheel shaft 23.
Referring to Fig. 2, on shown guide rail, be inclined-plane with carving the surface that piece 21 contacts, the described surface of matching with this surface on piece 21 of carving is also for having the inclined-plane of same slope.
As can be seen from Figure 2: carve piece 21 from right to left, its thickness degree size progressively diminishes, and forms gradient.
The gradient on above-mentioned inclined-plane, should be very little gradient, to guarantee to realize the self-locking action after locking.
Specifically: lathe bed 11 top guide rails described in the utility model have the inclined-plane that a dovetail inclined-plane is 1: 100; Described carves piece 21 with straight-tooth, and its plane is provided with the gradient of 1: 100.
Dovetail inclined-plane and carve the corresponding inclined-plane on piece 21, can, carving piece 21 positions while moving, realize the locking of overarm 12 or unclamp.
The installation method of slippage driving mechanism and overarm retaining mechanism 20:
As shown in Figure 3, first will carve piece 21 is arranged between lathe bed 11 top guide rails and overarm 12; Then overarm gear shaft 22 is installed on overarm locking teeth wheel shaft 23, formation is rotatably assorted; Again set lever bar 26 is installed on overarm locking teeth wheel shaft 23, with pin 31, is connected and fixed; Moving handle seat 24 is affixed in overarm gear shaft 22 by pin 32 again, has so just guaranteed that overarm locking teeth wheel shaft 23 is enclosed within overarm gear shaft 22, moving handle bar 25 can not produce axial float; Afterwards moving handle bar 25 is connected on moving handle seat 24 by pin 31; Finally slippage driving mechanism and overarm retaining mechanism 20 are mounted on lathe bed 11, and axis prevents from exiting to latch 33.
The method of operating of slippage driving mechanism and overarm retaining mechanism 20:
When needs are hung oneself from a beam 12 slippage, first operation locking handlebar 26, by its pinion and rack, moves to the direction of unclamping carving piece 21; Then, operation moving handle bar 25, by its pinion and rack, will hang oneself from a beam and 12 to needed direction, move, and after putting in place, stop; Finally, then operation locking handlebar 26, by its pinion and rack, by carving the direction of piece 21 to locking, move, by the same-action matching, 12 lockings of hanging oneself from a beam.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
