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 the sliding block for existing punching machine adjusts part and is improved, solve its adjust it is inconvenient,
Adjusting efficiency is low, degree of regulation is low, the relatively low lamp technical problem of safety coefficient, to improve the adjusting efficiency of slider of punch, adjust essence
Degree ensures the safety during adjusting.
As shown in Figure 1, a kind of 10 height adjustment mechanism of slider of punch of the present invention, it is suitable for the various punching machines such as punching press punching machine
In, including sliding block 10, guide post 20, adjustable column 30, worm gear 40 and worm screw 50.
Sliding block 10 is horizontally disposed, and guide post 20 erects setting, and there are two guide posts 20 and is spaced from each other, 20 one end of guide post and punching machine
Connecting rod flexible connection, there are two adjustable columns 30, and each 30 one end of adjustable column is threadedly coupled with corresponding guide post 20, the other end and
Sliding block 10 is connected, and there are two worm gears 40 and is respectively arranged on corresponding adjustable column 30, and there are two worm screws 50 and may be contained within sliding
On block 10, two worm screws 50 engage with corresponding worm gear 40 connect respectively.
During work, worm screw 50 rotates and makees gear motion with worm gear 40 so that and worm gear 40 drives adjustable column 30 to rotate synchronously,
And adjustable column 30 is connected through a screw thread with guide post 20, while adjustable column 30 rotates, is sent out in the vertical direction with respect to guide post 20
Raw displacement, so as to fulfill the adjusting of sliding block 10 in height, two adjustable columns, 30 synchronous shift realizes the same of 10 height on both sides of sliding block
Step section, synchronous effect are higher.
It is noted that mechanism is applicable not only to the adjusting of vertical direction top shoe 10, level can equally be well applied to
Sliding block 10 on direction is adjusted.
On the basis of the said structure, the present invention has made to be further improved and refine to it.
As shown in Fig. 2, the lower end of guide post 20 offers a mounting hole 21, swivel nut 22 is embedded in mounting hole 21, the spiral shell
Set 22 is connected by screw or bolt with guide post 20 in a manner of removable, and 30 upper end of adjustable column is stretched into swivel nut 22 and and swivel nut
22 are threadedly coupled.
The setting of swivel nut 22 realizes guide post 20 and is threadedly coupled with adjustable column 30, and when sliding block 10 works, larger rushes
It hits power easily to damage helicitic texture, this, which allows for helicitic texture, needs often maintenance or replace, otherwise, to influencing sliding block
10 normal regulating, and by by swivel nut 22 and 20 dismantled and assembled connection of guide post so that 22 easy disassembly of swivel nut is conveniently replaceable, with
Ensure the normal regulating of 10 height of sliding block.
As shown in Fig. 2, being provided with avoid holes 23 in the guide post 20, the swivel nut 22 and avoid holes 23 are coaxial, the tune
Segmented column 30 is simultaneously positioned at avoid holes 23 in swivel nut 22, the fuel feed hole communicated with avoid holes 23 is provided in 20 outer surface of guide post
24。
Avoid holes 23 provide required accommodation space for adjustable column 30 in 10 height of adjusting slider, to shorten entire guide post
20 with the entire length of adjustable column 30, save space, can be by fuel feed hole 24 to swivel nut 22 in addition, by setting fuel feed hole 24
Interior injection lubricating oil to improve the lubricity between adjustable column 30 and swivel nut 22, ensures flexibility when adjustable column 30 is adjusted.
As shown in Figure 2 and Figure 3, the worm gear 40 is cyclic structure, is sheathed on adjustable column 30, in worm gear 40 with adjusting
The limited block 31 being connected with adjustable column 30 is provided between column 30, the limited block 31 is respectively embedded into adjustable column 30 and worm gear 40.
Worm gear 40 is removable assembling structure with adjustable column 30, in this way, the assembling of worm gear 40 and adjustable column 30 can be facilitated, while
Can improve the flexibility ratio that later stage worm gear 40 and adjustable column 30 are conserved, replaced, and by setting limited block 31, realize worm gear 40 and
Limiting of the adjustable column 30 in rotation direction avoids worm gear 40 and situation about relatively rotating occurs with adjustable column 30, ensure that cunning
The normal regulating of block 10.
As shown in Figure 2 and Figure 3, mounting base 11 is fixed in the sliding block 10, the adjustable column 30 runs through mounting base 11, institute
It states worm gear 40 to be located in mounting base 11, installation sleeve 12 is extended in 11 side of mounting base, and the worm screw 50 is located at installation set
In cylinder 12 and 50 both ends of worm screw are flexibly connected with installation sleeve 12.
Further, gland 13 is fixed in the mounting base 11, gland 13 passes through removable mode with mounting base 11
It is connected, the adjustable column 30 passes through gland 13, and 13 lower end of gland is opposite with worm gear 40, and the worm gear 40 is located at 13 mounting base of gland
Between 11 and it can be against in gland 13 and mounting base 11.
Mounting base 11 and the setting of gland 13 so that worm gear 40 is located at a space for being relatively fixed, closing with worm screw 50
Both it is interior, while facilitating the dismounting of 40 worm screw 50 of worm gear, globality, the stability of worm gear 40 and worm screw 50 are improved, ensure that
Between transmission accuracy, and worm gear 40, between gland 13 and mounting base 11, avoid worm gear jumps about 40, ensure that worm gear 40
With the long transmission of worm screw 50.
As shown in Figure 1,10 outer surface of sliding block is provided with driving motor 14, the driving motor 14 passes through a fixed frame
14a is fixed on sliding block 10, and the motor shaft of driving motor 14 is stretched into sliding block 10 and is sequentially connected with two worm screws, 50 one end.
Two worm screws 50 is driven to rotate simultaneously by driving motor 14 so that two adjustable columns 30 can rotate synchronously, so as to real
The synchronous adjustment of existing 10 both ends height of sliding block, ensure that the levelness of sliding block 10, and the setting of driving motor 14, it can be achieved that its with
Control system is electrically connected, so as to by the instruction of system, 10 height of sliding block be adjusted at any time, convenient, reliable, adjusting effect
Rate is high.
During work, driving motor 14 works and rotates synchronously two worm screws 50, and two worm screws 50 nibble respectively with two worm gears 40
Resultant motion so that worm gear 40 drives adjustable column 30 to rotate synchronously, and adjustable column 30 is connected through a screw thread with guide post 20, adjustable column 30
It while rotation, is subjected to displacement with respect to guide post 20, is adjusted so as to fulfill the adjusting of sliding block 10 in height, two in the vertical direction
30 synchronous shift of segmented column realizes the synchronous adjustment of 10 height on both sides of sliding block.
