Specific embodiment
The following is specific embodiments of the present invention and with reference to attached drawing, technical scheme of the present invention is further described,
But the present invention is not limited to these embodiments.
It is an object of the present invention to be improved for existing punching machine structure, its each parts is solved because there are during gap
Lead to the problem of sliding block stability is poor, punching precision is poor, to eliminate gap, improve sliding block stability and punching precision.
As shown in Figure 1, a kind of 60 accuracy compensation mechanism of sliding block, including rack 10, eccentric shaft 20, connecting rod 30, guide post 40, is adjusted
Segmented column 50, sliding block 60 and lifting device.
Rack 10 erects setting, and eccentric shaft 20 is movably set in rack 10 and energy 10 eccentric rotary of opposite rack, connecting rod
30 upper ends are flexibly connected with eccentric shaft 20, and guide post 40 is articulated and connected with 30 lower end of connecting rod, 50 upper end of adjustable column and 40 screw thread of guide post
It connects and can be rotated relative to guide post 40, sliding block 60 is separated with rack 10, and sliding block 60 is flexibly connected with 50 lower end of adjustable column, works as bias
Axis 20 rotate when, the sliding block 60 can be reciprocating in the vertical direction, lifting device be fixedly arranged on 10 upper end of rack and with cunning
Block 60 is connected, and sliding block 60 can above be carried and is synchronized with the movement with sliding block 60 by the lifting device.
It before work, first passes through lifting device and is lifted up sliding block 60 so that eccentric shaft 20, guide post 40, is adjusted connecting rod 30
The gap of bottom works to moving up, and eccentric shaft 20, connecting rod 30, guide post 40, adjustable column 50 4 is caused to push against between column 50 4
When, eccentric shaft 20 rotates and connecting rod 30 is driven to rotate, and guide post 40, adjustable column 50 is driven to move successively, so as to fulfill sliding block 60
Reciprocating movement in the vertical direction, and lifting device is also synchronized with the movement with sliding block 60, in 60 motion process of sliding block, eccentric shaft
20th, connecting rod 30, guide post 40, adjustable column 50 4 push against always, are shaken in the movement direction so as to avoid each parts, improve
The stability and punching precision of sliding block 60.
On the basis of the said structure, the present invention has made to be further improved and refine to it.
As shown in Figs. 1-3, the lifting device includes oil cylinder 70 and piston rod 71, oil cylinder 70 erect setting and with rack 10
It is connected, piston rod 71 is set in oil cylinder 70 and lower end stretches out oil cylinder 70 and is connected with sliding block 60, and the piston rod 71 can be relatively oily
Cylinder 70 moves in the vertical direction, and before sliding block 60 moves, the piston rod 71 can lift sliding block 60, when sliding block 60 moves, institute
Stating piston rod 71 can be synchronized with the movement with sliding block 60.
Before sliding block 60 moves, pass through above carrying for piston rod 71 so that each parts push against, at this point, sliding block 60 is in relatively steady
Fixed state, during movement, the shift motion of piston rod 71 is identical with the shift motion of sliding block 60, both can guarantee each parts in this way
Always in abutting state, so as to ensure the proper motion of sliding block 60, its punching precision can also be improved.
As shown in Figure 1-Figure 3, connecting seat 61 is installed on the sliding block 60, dismantled and assembled connection is limited in 71 lower end of piston rod
Position block 72, the piston rod 71 stretches into connecting seat 61 and limited block 72 is against on connecting seat 61.
The setting of connecting seat 61 and limited block 72, facilitates piston rod 71 and is connect with sliding block 60, and piston rod 71 is passed through and connected
Joint chair 61 simultaneously passes through limited block 72 and is against on connecting seat 61 so that piston rod 71 and the bonding strength of connecting seat 61 are higher, are not easy
Separation.
As shown in Figure 2 and Figure 3, be arranged with compensation block 73 on the piston rod 71, the compensation block 73 be located at limited block 72 with
It is butted between connecting seat 61 and respectively on limited block 72 and connecting seat 61, it is preferred that the compensation block 73 is opposite with limited block 72
Surface is inner concave 73a, and arcuate surface 72a is correspondingly provided on the limited block 72, and the inner concave 73a and arcuate surface 72a is supported
Tightly.
Compensation block 73, with cushioning effect, can reduce the phase interaction between the two between connecting seat 61 and limited block 72
Firmly, the stability of piston rod 71 and sliding block 60 is improved, in addition, compensation block 73 is mutual by chimeric male and fomale(M＆F) with limited block 72
Cooperation, the two compensation block 73 are bonded more closely with limited block 72, are further obviated existing between compensation block 73 and limited block 72
Gap further improves the stability and punching precision of sliding block 60.
As shown in figure 3, the connecting seat 61 includes fixed block 61a and link block 61b, there are two fixed block 61a and erects
Setting, two fixed block 61a are spaced from each other, and link block 61b is connected with two fixed block 61a upper ends by bolt or screw, the work
Stopper rod 71 passes through link block 61b and compensation block 73 is against respectively on link block 61b and limited block 72.
Connecting seat 61 uses this structure, convenient to be connect with piston rod 71, can be first by piston rod 71 and link block during connection
Then 61b connections are fixed link block 61b on two fixed block 61a, improving the flexibility of assembling.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
