Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
Jointly shown with Fig. 3 as shown in Figure 1, Figure 2, a kind of clamping fixture, including pedestal 10, is provided with power set on pedestal 10
30 and product base 20.Power set 30 are cylinder, and the power output part of power set 30 is piston rod.The end of piston rod
First pushing block 40 is rotatablely equipped with by the first vertically arranged pivot pin 41, the both ends of the first pushing block 40 are respectively by vertically arranged
The second pivot pin 42 be rotatablely equipped with the second pushing block 50.Product base 20 is equipped with multiple storage tanks for being used to place product 21,
It is equipped between the end of second pushing block 50 and the product 21 opposite with the end of the second pushing block 50 and promotes 60, promotes 60 both ends point
On the end and product 21 for not acting against the second pushing block 50.It is provided with pedestal 10 between second pushing block 50 and product base 20
Guide holder 70, guide holder 70 are equipped with for promoting 60 pilot holes passed through, promote 60 and be inserted into pilot hole.
As Fig. 4 and Fig. 5 are jointly shown, 60 pin caps of the one end being in contact with the second pushing block 50 equipped with circumferential projection are promoted,
Pilot hole on guide holder 70 is stepped hole, promotes 60 positions in the large aperture of pilot hole and is arranged with spring 61, spring
61 both ends act against on the cascaded surface of pin cap and pilot hole respectively.
As shown in figure 5, the position that the small-bore of pilot hole is corresponded on guide holder 70 is vertically equipped with the spacing of connection pilot hole
Pin hole, spacer pin 62 is provided with limit pin hole, is promoted 60 and is moved the consistent keyway 63 in direction equipped with extending direction, limit
The end of position pin 62 is extend into keyway 63, and keyway 63 is the groove for not extending radially through distribution 60.
As shown in figure 4, it is the imitated structure that is adapted with product 21 to promote 60 close to one end of product base 20.Second pushes away
The end of block 50 is equipped with arc convex close to the side for promoting 60.
One end that first pivot pin 41 and the second pivot pin 42 expose the first pushing block 40 is separately installed with E types buckle.
When this gauge works, power set 30 drive the first pushing block 40 and the second pushing block 50 to be moved to guide holder 70, and second
The end of pushing block 50 with promote 60 one end be bonded, and to promote 60 application pressure so that spring 61 compress and promote 60 it is another
One end compresses product 21, and since the first pushing block 40 can turn an angle along the first pivot pin 41, the second pushing block 50 can be along second
Pivot pin 42 turns an angle, so the first pushing block 40 and the second pushing block 50 meeting adjust automatically angle, so that the second pushing block 50
The power that is subject to of end be equal, i.e., the power that product 21 is subject to also is equal.When power set 30 are retracted, the bullet on 60 is promoted
Spring 61 unclamps so that promotes 60 and sets back in guide holder 70, product 21 is unclamped in the distribution 60 for compressing product 21 at this time.
In the present embodiment, keyway 63 is the groove for not extending radially through distribution 60, wherein, keyway can also be to extend radially through to push away
The through hole of pin 60, only needs accordingly to lengthen spacer pin 62, ensures that spacer pin 62 can coordinate limitation to promote 60 with keyway 63
Stroke.
In the present embodiment, the first pushing block 40 is provided with 1, and the product 21 of clamping is 4.If it is not provided with the first pushing block
40, power set 30 are directly connected with the second pushing block 50, i.e., the gauge only has second pushing block 20, the then product 21 that can be clamped
For 2.If the first pushing block 40 is arranged to 2, attachment device is set between 30 and first pushing block 40 of power set, then can be pressed from both sides
Tight product 21 is 8.And so on, the number for the product 21 that can be clamped can also be 16,32,64 or other 2 indexes times
Number.
The clamping fixture of the utility model by set can autobalance both ends power the second pushing block and with the second pushing block connect
The first pushing block for connecing and turning an angle so that the power being subject to during each clamping product is equal, and avoiding portioned product cannot press from both sides
Tight situation, realizes that a gauge simultaneously clamps on multiple products.
Although the foregoing describing specific embodiment of the present utility model, it should be appreciated by those skilled in the art,
Described embodiment is only the part of the embodiment of the utility model, and instead of all the embodiments, these are only to lift
Example explanation, the scope of protection of the utility model is to be defined by the appended claims.Those skilled in the art is without departing substantially from this
, can be to these embodiments under any performing creative labour of no process on the premise of the principle and essence of utility model
Various changes or modifications are made, but these change and modification each fall within the scope of protection of the utility model.
