State the concrete meaning of term in the present invention.
A kind of locking limiting device with regulatory function of the utility model, is connected with rotating mechanism thereon.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of locking limit with regulatory function of the utility model
Device includes rack 1, spacing collar 2, rotating bar 3 and fastening assembly 4.
Rack 1 includes upper mounted plate 11 and bottom plate 12, and first through hole 13, bottom plate are provided on upper mounted plate 11
Second through-hole 14 corresponding with first through hole 13 is provided on 12.
Spacing collar 2 is connected in first through hole 13, and at least four taper holes 21 are provided on spacing collar 2.
There are two threaded holes 31, rotating bar 2, and spacing collar 2, the second through-hole 14 to be passed through to be connected to rack for setting in rotating bar 3
On 1.
Fastening assembly 4, which is connected on threaded hole 31 and taper hole 21, makes rotating bar 3 be fixedly connected on spacing collar 2.
Rotating mechanism is socketed in rotating bar 2 and between upper mounted plate 11 and bottom plate 12.
In the present invention, rotating mechanism be socketed in rotating bar 2 and in upper mounted plate 11 and bottom plate 12 it
Between, not radial motion is allowed to limit being allowed to be axially moved by rotating bar 2;Fastening assembly 4 is connected to 31 He of threaded hole
So that rotating bar 3 is fixedly connected on spacing collar 2 on taper hole 21, it is locking that progress is fastened by fastening assembly 4;It needs to adjust
When, fastening assembly 4 is unclamped, so that rotating bar is rotated by a certain angle, so that threaded hole 31 is matched other taper hole 21, then tighten fastening group
Part is adjusted by the threaded hole 31 of the taper hole 21 of spacing collar 2 and rotating bar 3, make its be provided simultaneously with limit, it is locking and
Regulatory function.
As shown in Figure 4 and Figure 5, in the present invention, spacing collar 2 includes integrally formed annulus 22 and cylinder 23,
It is provided with taper hole 21 on annulus 22, further, 6 ~ 12 taper holes 21 are provided on annulus 22;Preferably, being arranged on annulus 22
There are 10 taper holes, 21,10 taper holes 1 to be evenly distributed on the upper surface of annulus 22.
As shown in fig. 6, rotating bar 3 includes integrally formed head 32 and stock 33, there are two screw threads for setting in head 32
Hole 31, is conveniently tightened.
In the present invention, as shown in Figures 2 and 3, fastening assembly 4 includes the tapered end holding screw that its head is taper
41 and fastening nut 42, tapered end holding screw 41, which is connected on threaded hole 31 and taper hole 21, makes rotating bar 3 be fixedly connected on limit
On sleeve 2;Fastening nut 42 is in the lower section of bottom plate 12 and is threadedly coupled with the stock 33 of rotating bar 3.
In the present invention, spacing collar 2 is welded in first through hole 13, is allowed to be fixedly connected, and is not easy to loosen, limit
The material of sleeve 2 is aluminium material.
In the present invention, what fastening nut 42 was selected according to actual needs is that a kind of locking nut thread structure is
Apply must firm structure, the specification of nut is M12;Rack 1 is for fixing spacing collar 2, using rectangle pipe material, by welding
At having the mounting hole of spacing collar 2 in the drilled in middle of tubing;Spacing collar 2 is passed through using bar to be machined into, and and rack
1 welds together, and the upper surface of spacing collar 2 is drilled with taper hole 21, passes through inner cone and the spacing collar 2 of tapered end holding screw 41
Taper hole 21 taper-face contact, by helicitic texture give rotating bar apply pressure, under the reaction of fastening nut 42, generate foot
Enough frictional force makes rotating bar 3 keep current location constant, realizes limit function;Rotating bar 3 uses metal bar, by machine
It is process, mainly realizes rotating function, there are two the threaded holes of M4 for processing in the head of the hexahedron of 3 upper end of rotating bar
31, for installing two tapered end holding screws 41;Tapered end holding screw 41 is in the threaded hole 31 of rotating bar 3.
The utility model is simple in structure, compact, limit is reliable and has flexible controllability, with common rotating machine
The limiting device of structure is compared and is had the following advantages:
(1)The utility model is coordinated by simple multiple taper holes 21 and two tapered end holding screws 41, is realized flexibly simultaneously
More accurate positioning function, although and common positioning device is the registrations such as spacer pin, it is dumb.
(2)When limit, rotating bar 3 is adjusted to suitable position by corresponding tool, is tightened and is bored by corresponding tool
Holding screw 41 is held, makes the taper-face contact of the inner cone of tapered end holding screw 41 and the taper hole 21 of spacing collar 2, passes through screw thread knot
Structure applies pressure to rotating bar 3 and generates enough frictional force under the reaction of fastening nut 42, and rotating bar 3 is made to keep current
Position is constant;And although existing position limiting structure such as spacer pin also can guarantee limit, assembly is slower, and position is fixed without side
It can modulability.
(3)When adjusting, the tapered end holding screw in two threaded holes 31 in rotating bar 3 is unclamped by suitable tool
41, so that its preceding tapered end is exited the taper hole 21 of spacing collar 2 completely, adjusting rotating bar 3 with suitable tool arrives suitable position, then
Tighten the tapered end holding screw 41 in two threaded holes 21 in rotating bar;And existing regulative mode needs to take out spacer pin,
It either unclamps after the completion of other position limiting structures etc. wait adjustings and refills upper arresting pin or the other position limiting structures of fastening, it cannot
Very easily complete adjustment process.
(4)The utility model is simple in structure, easy to adjust, easily manufactured;And existing limiting device, manufacture difficulty are high,
Manufacturing cost is high.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
