Description
Technical field
This utility model relates to a kind of frame for movement, especially a kind of rack-and-pinion transition link formula clamp structure.
Background technology
The open a kind of rack-and-pinion transition link formula clamper of Chinese patent ZL2014202213883, this clamping
Device is translated by driver drives tooth bar, thus drives the sector gear that is meshed to rotate, sector gear further through
The connecting rod being connected drives chela to tighten up, thus realizes clamping；This rack-and-pinion transition link formula clamper
Exist technical problem is that: driver is positioned at guide-localization set, and driver is parallel-moving type, and driving force is less,
Being difficult to be locked at fixed position, after tooth bar and quadrant drive, the power of output is less so that the folder of chela
Clamp force is limited, and chela easily unclamps because driver is not fixed easily, and impact uses.
Owing to there is problems in that, it is therefore necessary to existing rack-and-pinion transition link formula clamp structure is entered
Row improves.
Summary of the invention
The purpose of this utility model is that a kind of clamping effect designed to solve the deficiency of above-mentioned technology is good
Rack-and-pinion transition link formula clamp structure.
Rack-and-pinion transition link formula clamp structure designed by this utility model, including support, support sets
There is the toothed tooth bar in both sides, be provided with meshed and rotating sector gear, described fan in tooth bar both sides
Connecting on shape gear has connecting rod, connecting rod bottom to be provided with chela；Described support is provided with top chock and lower bearing
Seat, is designed with bearing in described top chock and step；Described tooth bar center is bolted with one through being somebody's turn to do
The screw rod of tooth bar, described screw rod two ends lay respectively in the bearing on top chock and step；At screw rod
Top is provided with shaft coupling；Be additionally provided with two guide rods in left and right in described screw rod both sides, described guide rod is positioned at upper bearing (metal)
Between seat and step, and described guide rod is through described tooth bar.
As preferably:
Described guide rod top has positive stop end.
Described guide rod top is provided with thread segment, and described thread segment and the screw on top chock form screw thread and join
Close.
Rack-and-pinion transition link formula clamp structure designed by this utility model, it provides the benefit that: join
Axial organ can connect the motor shaft of motor or the output shaft of reductor, use the axle rotated as input power,
After shaft coupling rotates, screw rod is driven to rotate, owing to screw rod through tooth bar center and is spirally connected with tooth bar, simultaneously
Tooth bar is limited by two guide rods, and such tooth bar can only upper and lower translation, it is impossible to rotate；The power that shaft coupling rotates
Having reformed into the power of tooth bar translation, after tooth bar translation, the sector gear that is meshed with it can rotate, thus carries
Two connecting rods in dynamic left and right are opened opposite to each other and close, and then realize opening and closing of chela bottom connecting rod.
This rack-and-pinion transition link formula clamp structure, chucking power is relatively big, and once after clamping, due to tooth bar
Can not rollback, therefore, would not unclamp after clamping, it follows that this rack-and-pinion transition link formula folder
Holding structure when clamping article, a pair chela is bigger to the chucking power of article, and article are in clamping process
More stable, do not have situations such as slipping or fall, it can be ensured that using effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1 rack-and-pinion transition link formula clamp structure；
Fig. 2 is the enlarged drawing in Fig. 1 at A；
Fig. 3 is the enlarged drawing at embodiment 2 top chock；
In figure: support 1, tooth bar 2, sector gear 3, connecting rod 4, chela 5, top chock 6, lower bearing
Seat 7, bearing 8, screw rod 9, shaft coupling 10, guide rod 11, positive stop end 12, thread segment 13, screw 14.
Detailed description of the invention
The utility model will be further described to combine accompanying drawing below by embodiment.
Embodiment 1:
As shown in Figure 1, 2, the rack-and-pinion transition link formula clamp structure described by the present embodiment, including
Support 1, support 1 is provided with the toothed tooth bar in both sides 2, is provided with meshed and can in tooth bar 2 both sides
The sector gear 3 rotated, described sector gear 3 connects and has connecting rod 4, connecting rod 4 bottom to be provided with pincers
Pawl 5；Described support 1 is provided with top chock 6 and step 7, described top chock 6 and lower bearing
It is designed with bearing 8 in seat 7；Described tooth bar 2 center is bolted with a screw rod 9 through this tooth bar 2, institute
State in the bearing 8 that screw rod 9 two ends lay respectively on top chock 6 and step 7；On screw rod 9 top
It is provided with shaft coupling 10；Be additionally provided with two guide rods 11 in left and right in described screw rod 9 both sides, described guide rod 11 is positioned at
Between top chock 6 and step 7, and described guide rod 11 is through described tooth bar 2, described guide rod 11
Top has positive stop end 12.Such structure, the installation of guide rod 11 is very convenient, inserts peace from top to bottom
Filling, be clamped in step 7 bottom guide rod 11, top is spacing by positive stop end 12, such guide rod
11 is the most firm.Certainly, guide rod 11 also can use other mechanical connection manner.
Wherein, chela can use clipping chela of the prior art or inner bearing type chela also or folder
Hold, internal stay convolution chela.
Rack-and-pinion transition link formula clamp structure described by the present embodiment, it provides the benefit that: shaft coupling
Device 10 can connect the motor shaft of motor or the output shaft of reductor, uses the axle rotated dynamic as input
Power, after shaft coupling 10 rotates, drives screw rod 9 to rotate, owing to screw rod 9 is through tooth bar 2 center and and tooth
Bar 2 is spirally connected, and is limited by two guide rods 11 with hour rack 2, and such tooth bar 2 can only upper and lower translation, it is impossible to
Rotate；The power that shaft coupling 10 rotates has reformed into the power of tooth bar 2 translation, after tooth bar 2 translation, nibbles mutually with it
Close sector gear 3 can rotate, thus drive two connecting rods 4 in left and right open opposite to each other and close, and then
Realize opening and closing of chela 5 bottom connecting rod 4.This rack-and-pinion transition link formula clamp structure, folder
Holding force is relatively big, and once after clamping, due to tooth bar 2 can not rollback, therefore, would not unclamp after clamping,
It follows that this rack-and-pinion transition link formula clamp structure is when clamping article, a pair chela is to article
Chucking power relatively bigger, article are more stable in clamping process, do not have slippage or the feelings such as fall
Condition, it can be ensured that using effect.
Embodiment 2:
As it is shown on figure 3, the rack-and-pinion transition link formula clamp structure described by the present embodiment, with embodiment
Unlike 1: described guide rod 11 top is provided with thread segment 13, on described thread segment 13 and top chock 6
Screw 14 form threaded engagement.
So, the installation of guide rod 11 is more convenient, guide rod 11 from upper toward sequentially pass through downwards top chock 6,
Tooth bar 2 and step 7, the thread segment 13 of final guide rod 11 is screwed in screw 14, such guide rod 11
With regard to installation, easy for installation, and basic guide effect can be played, the guide rod 11 when tooth bar 2 moves
Will not loosen, the stability of use can be improved.
Above-described embodiment is only explanation for example to design of the present utility model, it will be apparent that, the protection of this patent
Scope is not limited to above-described embodiment.
The various equivalent modifications or supplementary that above-described embodiment is made by those skilled in the art, all should fall into this specially
The protection domain of profit.
