Description
Technical field
The present invention relates to a kind of feed devices of lathe, and in particular to a kind of adjustable bed.
Background technique
In machine tooling assembly, workpiece after fixture clamps, is needing to carry out workpiece in multi-faceted berry, it usually needs
The position of workpiece is adjusted, often dismantles workpiece on fixture, not only working efficiency is low, but also fixture is also easy mill
Damage, current workbench are all fixed settings, and workbench adjustment position is inconvenient.
Summary of the invention
The shortcomings that can not being adjusted the technical problem to be solved by the present invention is to the position of workbench in the prior art.
In order to solve the above technical problem, the present invention provides a kind of adjustable beds, including rack, motor, slide bar and cunning
Seat, the slide bar both ends are arranged on the rack, and slide is connect with sliding bar, and workbench can be set on slide, the cunning
It is arranged with teeth on seat, the side of the tooth of slide is provided with wishbone, and a fixed jaw, other end hinge is fixedly installed in described wishbone one end
The moving jaws inwardly rotated are connect, are provided with torsional spring in the pin shaft of moving jaws；It is provided with nose bar in the middle part of wishbone, nose bar is combined with
Ratchet, ratchet connect the shaft of motor；Tension spring is provided between nose bar and rack.
Adjustable bed by adopting the above technical scheme has the advantages that motor band moving cam rotates, and cam pushes convex
Bar wishbone is swung, and the fixed jaw and moving jaws of wishbone end and the tooth on slide cooperate, and moves slide on slide bar.Due to
Moving jaws can only one-directionally rotate, and after moving jaws promote the tooth on slide again, tooth can be blocked after resetting by torsional spring, prevents its time
It moves.Tension spring assists wishbone to reset.Since workbench is arranged on slide, slide drives movable workbench, realizes that workbench is adjustable
Section.
It is further, uniformly distributed on the ratchet that there are six ratchets.Structure is simple, the operation is stable.
Further, pulley is equipped in the slide, the wheel face of the pulley is groove type.Groove and slide bar cooperate, and make to slide
Seat sliding is smooth.
Detailed description of the invention
Fig. 1 is the schematic diagram of adjustable bed of the present invention.
Specific embodiment
Appended drawing reference in Figure of description includes: slide bar 1, slide 2, tooth 3, wishbone 4, moving jaws 5, nose bar 6, ratchet
7, tension spring 8.
Further explanation of the technical solution of the present invention with reference to the accompanying drawings and examples:
As shown in Figure 1, a kind of adjustable bed, including rack, motor, slide bar 1 and slide 2,1 both ends of slide bar pass through
Screw and nut are fixed on the rack, and slide 2 is slidably connected with slide bar 1, reeded pulley at slide 2 and 1 cooperation of slide bar, this
Embodiment is preferably V-type pulley, and workbench and slide 2 weld, and slide is evenly distributed in the upper surface with teeth 3, the machine of the top of the tooth 3 of slide
Wishbone 4 is installed, described 4 one end of wishbone is a fixed jaw, and the moving jaws 5 that the other end hinged one inwardly rotates are mobile on frame
It is provided with torsional spring in the pin shaft of pawl 5, tooth 3 can be blocked after resetting by torsional spring, prevents slide from moving back；It is extended in the middle part of wishbone 4
Nose bar 6, nose bar 6 and ratchet 7 cooperate, and motor band moving cam rotates, and cam pushes nose bar 6 to swing wishbone 4,4 end of wishbone
Fixed jaw and moving jaws 5 and slide 2 on tooth 3 cooperate, move slide on slide bar 1.Ratchet 3 and cam on ratchet 7
The position of contact is arc surface, and ratchet 7 connects the shaft of motor；.Tension spring 8, the ratchet 7 are connected between nose bar 6 and rack
Above uniformly distributed there are six ratchets 3, since moving jaws 5 can only one-directionally rotate, after moving jaws 5 promote the tooth 3 on slide again.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without departing from the structure of the invention, several modifications and improvements can also be made, these also should be considered as guarantor of the invention
Range is protected, these all will not influence the effect and patent practicability that the present invention is implemented.
