Fig. 2 shows the utility model overall structure stereograms two.
Fig. 3 shows the utility model overall structure front view.
Specific embodiment
It is practical to this below in conjunction with attached drawing in order to keep the purpose of this utility model, technical solution and advantage clearer
It is novel to be described in further detail.
As shown in Fig. 1 ~ Fig. 3, a kind of processing of valve tappet outer surface clamping device, including elevating mechanism 10, Yi Jishe
Clamping part in 10 top of elevating mechanism.
Specifically, clamping part include L-type bottom plate 20 and be relatively arranged on 20 surface of L-type bottom plate the first clamp structure and
Second clamp structure, 20 one end of L-type bottom plate are concave wall 21, and the other end is equipped with card slot 23, is arranged with limit plate 24 in card slot 23,
First clamp structure is fixed on 21 side of concave wall of L-type bottom plate 20, and the second clamp structure, which is located at, is snug fit at L-type bottom plate 20
Inverted T shaped sliding slot 22 in inverted T shaped sliding block 53 on.
As specific embodiment, the first clamp structure includes that a pair is arranged at intervals at the first of 20 surface of L-type bottom plate
Pillar 40 and the first circular arc body 41 at the top of the first pillar 40, the second clamp structure includes that a pair is arranged at intervals at pushing tow
The second pillar 50 on block 52, the second circular arc body 51 set on 50 top of the second pillar, 52 bottom of push block is connected to inverted T shaped
53 top of sliding block.
Augering screw 30 is equipped in concave wall 21, augering screw 30 and the screw hole of concave wall 21 are threadedly engaged, and promote spiral shell
The front end of bar 30 is taper platform 31, the cone tank 54 of 31 face push block of taper platform, 52 side.
When implementing, mechanism is assembled first: limit plate 24 wouldn't be installed, the second clamp structure is first passed through into its bottom
The inverted T shaped sliding block 53 of portion's connection is slidably matched to the inverted T shaped sliding slot 22 of L-type bottom plate 20, is then caught in limit plate 24；It will promote
Screw rod 30 is threadedly engaged in concave wall 21, and wears the state for reaching to be performed into certain distance.
Specifically, can pass through between the first pillar 40 after augering screw 30 passes through concave wall 21.
When the specific operation for carrying out this programme is implemented, valve tappet is placed in the first circular arc body 41 and the second circular arc first
On body 51, the first circular arc body 41 and the second circular arc body 51 is made to protrude into the inner cavity of valve tappet, free support valve tappet；Operation pushes away
It into screw rod 30, promotes taper platform 31 to cone tank 54, and taper platform 31 is cooperated in cone tank 54, forms pushing tow state；After
It is continuous to promote, make the second circular arc body 51 continue to be displaced outwardly, makes the first circular arc body 41 and the second circular arc body 51 to valve tappet inner cavity
Tensioning is formed, stable clamp position is reached.
Due to there is limit plate 24, also effectively prevents, in maloperation, the second clamp structure is made to skid off L-type bottom plate 20.
As specific embodiment, the first circular arc body 41 and the second circular arc body 51 are elastic rubbery body, are effectively provided
Tensioning support force flexible avoids causing to damage to tappet internal chamber wall；And first circular arc body 41 and the second circular arc body 51 it is opposite
Face is plane, and lateral surface is cambered surface, and lateral surface is equipped with corrugated protrusion, convex using the lateral surface and corrugated of arc
It rises, good contact effectively can be formed to internal chamber wall, improve and more stable shore effect.
As specific embodiment, elevating mechanism 10 can choose jacking cylinder, can effectively realize to L-type bottom plate
20 descending operation.When specifically used, elevating mechanism 10 can be fixed on station.
The utility model may be implemented conveniently, stable tappet be tensioned and supported from tappet inner cavity, additionally it is possible to root
The adjusting of height is supported according to use demand, which, which can be used alone, is used cooperatively after array with station etc., real
With property height.
