Specific implementation mode
For the ease of the understanding of those skilled in the art, the present invention is made further with reference to embodiment and attached drawing
Bright, the content that embodiment refers to not is limitation of the invention.The present invention is described in detail below in conjunction with attached drawing.
A kind of automatic assembly and disassembly filature for CNC fixtures provided by the invention includes cabinet 1 and is fixed on cabinet 1
The supporting rack 2 of top is equipped with screw mounting mechanism 3 on support frame as described above 2, and the upper surface of the cabinet 1 is provided with and the spiral shell
Silk mounting mechanism 3 is corresponding and to position the fixture location structure 4 for placing CNC fixtures, and the screw mounting mechanism 3 includes
It is vertically moved up or down component 5 and rotation assembly and disassembly component 6, the lower end for being vertically moved up or down component 5 is connect with rotation assembly and disassembly component 6, described vertical
Lifting assembly 5 drives rotation assembly and disassembly component 6 vertically to be moved up and down with respect to supporting rack 2, the rotation assembly and disassembly component 6
Lower section is equipped with the electric screw driver 7 to the turn of the screw, and the front end of electric screw driver 7 is detachably equipped with screwdriver bit 8.
When carrying out assembly and disassembly screw using the present invention, CNC fixtures are positioned on fixture location structure 4, vertical lift group
Part 5 drives rotation assembly and disassembly component 6 downward, rotation assembly and disassembly component 6 drive counterclockwise the electric screw driver 7 and screwdriver bit 8 to
On, screw dismounting is got off in realization, and then completes the dismounting of product;After the product of CNC fixtures is removed, install immediately
Another product, after being reinstalled product, rotation assembly and disassembly component 6 drive clockwise the electric screw driver 7 and screwdriver bit 8 to
Under, realize automatic tightening screw, and then complete installation of the product on CNC fixtures.The present invention is instead of manually to CNC fixtures
The loaded down with trivial details work for assembling and disassembling screw is substantially shorter the screw assembly and disassembly time, improves the working efficiency of screw assembly and disassembly, reduces operating personnel
Labor intensity, reduce production cost.
In the present invention, the vertical lift component 5 includes the servo lifting motor 51 for being fixed on 2 top plate of supporting rack,
The lower section of the servo lifting motor 51, which is drivingly connected, a vertical drive lead screw 52, is provided on drive lead screw 52 and lead screw
The lifting slider (not marked in figure) of screw-thread fit, the lifting slider, which is fixedly connected, is useful for having supported the rotation assembly and disassembly group
The support transverse slat 9 of part 6.The servo lifting motor 51 drives drive lead screw 52, and then drives support transverse slat 9 with respect to supporting rack 2
It moves up and down;Since on the rotation assembly and disassembly installation support transverse slat 9 of component 6, the height of rotation assembly and disassembly component 6 can pass through servo liter
Motor 51 drops to control;When carrying out tearing screw open, servo lifting motor 51 reduces the height of rotation assembly and disassembly component 6, convenient for rotation
Assemble and disassemble the screw on the dismounting CNC fixtures of component 6;After screw dismounting, the servo lifting motor 51 promotes rotating dress at once
The height for tearing component 6 open takes the product on CNC fixtures away convenient for worker.After reapposing product, servo lifting motor 51 is again
The secondary height for reducing rotation assembly and disassembly component 6 screws on the screw on CNC fixtures convenient for rotation assembly and disassembly component 6.So repeat loading and unloading
Work is tampered, the loaded down with trivial details work for manually assembling and disassembling screw to CNC fixtures is substituted, high degree of automation improves production efficiency.
Further, four angles of the support transverse slat 9 are respectively arranged with a lifting guide post 10, and the lifting is oriented to
The lower end of column 10 is fixed on support transverse slat 9, and 2 top plate of support frame as described above corresponds to and is provided through guiding at lifting guide post 10

Two fixed blocks 144, the lower ends of two fixed blocks 144 are fixedly mounted that there are one electromagnetism fixed seats 142 respectively, suck steel plate 143
It is fixedly installed in the lower end of two electromagnetism fixed seats 142.
The CNC fixtures upper end that the present invention is applied is provided with for compressing the fixture cover board above product, by product orientation
It is positioned over after CNC fixtures, fixture cover board is pressed on product and just carries out lock screw.When carrying out tearing screw open, fixture positioning knot
Structure 4 is first moved upwards CNC clamp pressings in the lower section of Suction plate mechanism 14, and then rotation assembles and disassembles component 6 and just downwards twists screw
Under demolition;When screw is removed, electromagnetism fixed seat 142, which is powered, so that sucking steel plate 143 there is magnetism, two pieces of left and right to suck
Steel plate 143 will suck the fixture cover board, at this point, the fixture location structure 4 moves downwardly together with CNC fixtures, product is naked
It is exposed above CNC fixtures, worker can directly be removed product with hand, reappose one piece of product in CNC fixtures immediately.Then
Fixture location structure 4 and CNC fixtures move upwardly together, and are pressed in the lower section of fixture cover board, at this point, rotation assembly and disassembly component 6
Downwards by screw tightening on CNC fixtures.
Further, the steel plate 143 that sucks is separated into three screw assembly and disassembly by two electromagnetism fixed seats 142
Section 15, each screw assembly and disassembly section 15 correspond to a rotation assembly and disassembly component 6, and the steel plate 143 that sucks is assembled and disassembled in each screw
The screw through-hole 145 passed through for screwdriver bit 8 is offered on section 15.The top in each screw assembly and disassembly section 15 is individually
Corresponding one does not have interference effect from each other screwdriver bit 8 when assembling and disassembling screw.
Further, each screw assembly and disassembly section 15 is respectively provided with that there are one screws to hold up structure, the screw support
It includes a double-rod cylinder 146 and right angle supporting block 147, side and the double-rod cylinder 146 of the right angle supporting block 147 to play structure
Piston rod be fixedly connected, the other side of right angle supporting block 147 is equipped with the U-shaped card slot 148 at the top of screw for Kato.It is described
For rotation assembly and disassembly component 6 when unscrewing screw counterclockwise, when persistently rotating counterclockwise about 1 second, the double-rod cylinder 146 is inwardly
It stretches out, and the U-shaped card slot 148 in right angle supporting block 147 is stuck at the top of screw, supporting role is risen to screw;Pass through control
Servo lifting motor 51 processed is moved synchronously with rotation assembly and disassembly component 6, and 147 support of right angle supporting block screw and rotation assembly and disassembly group
Part 6, which synchronizes, to be risen, so that screw will be retained in U-shaped card slot 148, convenient that adjusting screw is not spent when tightening screw
Position.
In the present invention, the quantity of the fixture location structure 4 is two, and described two fixture location structures 4 are top
Pin type location structure, the thimble-type location structure include the fixture side for jacking up 41 top of cylinder 41 and installation jack-up cylinder
Support plate 42, the lower end for jacking up cylinder 41 are fixed on cabinet 1, the upper center setting of fixture side support plate 42
It is useful for the taper pin 43 of positioning, the both sides of fixture side support plate 42 are also respectively provided with side guide post 44 and side is oriented to
Set 45.The taper pin 43 is fixed in fixture side support plate 42, and worker is facilitated accurately to place CNC fixtures;It is described
