SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a convenient simple special drilling machine of valve processing of implementation step of fixing the valve centre gripping in workstation required position is provided.

The utility model discloses a realize through following technical scheme:

a drilling machine special for machining a valve comprises a base, a stand column, a rocker arm and a workbench, wherein one end of the stand column and the workbench are respectively fixed on the base, one end of the rocker arm is arranged at the top of the stand column, a concave convex groove is formed in the upper surface of the workbench, a fixed bearing is arranged in one end of the convex groove and is welded on the workbench, a supporting bearing is arranged in the other end of the convex groove and is welded on the workbench, a lead screw is further arranged in the convex groove and is welded on the fixed bearing, the other end of the lead screw penetrates through the supporting bearing and is provided with a handle at the tail end of the supporting bearing, two movable clamp bodies are further arranged on the lead screw and are in threaded connection with the lead screw, the thread directions of the two movable clamp bodies are opposite, and anti-skidding grooves are further formed in opposite surfaces of the movable clamp bodies, the anti-slip grooves are criss-cross strip grid-shaped grooves.

Furthermore, the two movable pliers bodies are provided with pliers body mounting holes, and the pliers body mounting holes are through holes formed along the axial direction of the screw rod.

Beneficial effects of the utility model

The utility model provides a pair of special drilling machine of valve processing only need drive the lead screw rotation through waveing the handle, and two activity pincers bodies are earlier to the displacement on the lead screw, realize the clamp of valve part tightly or loosen soon, needn't move clamping tools such as bench vice to the workstation on fixed, adjustment, use.

Further, set up the pincers body mounting hole on the activity pincers body, meet sensitive part and need install the bed course additional and prevent to use modes such as bolt fastening or iron wire binding to install the bed course additional on the keeping silent of activity pincers body when pressing from both sides the injury.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure, 1, a base, 2, a column, 3, a rocker arm, 4, a fixed bearing, 5, a workbench, 6, a movable clamp body, 7, an anti-skidding groove, 8, a screw rod, 9, a clamp body mounting hole, 10, a supporting bearing, 11, a convex groove and 12, a handle are arranged.

Detailed Description

As shown in fig. 1, the utility model provides a pair of special drilling machine of valve processing, the bottom is base 1, the welding has stand 2 on the base, rocking arm 3 is equipped with at the stand top, 3 below of rocking arm are workstation 5, workstation 5 welding is on base 1, the recess is opened to workstation 5 upper surface, convex groove 11 promptly, it has fixing bearing 4 to weld at its one end, the other end has the support bearing 10 of welding on workstation 5, still be equipped with a lead screw 8 in the convex groove 11, the one end welding of lead screw 8 is in on fixing bearing 4, the other end passes support bearing 10 and is equipped with handle 12 at its end, middle part threaded connection has two movable pincers bodies 6, the screw direction of two movable pincers bodies 6 is opposite, still be provided with vertically and horizontally staggered's strip check form recess on the face in opposite of movable pincers body 6, antiskid recess 7 promptly. In order to conveniently use the modes of bolt fixing, iron wire binding and the like to additionally mount the cushion layer on the jaw of the movable clamp body when the cushion layer is required to be additionally mounted to prevent clamping sensitive components, a through hole, namely a clamp body mounting hole 9 is specially formed in the movable clamp body 6 along the axial direction of a screw rod 8.

During the use, wave handle 12, make lead screw 8 rotatory and drive the motion of activity pincers body 6 in opposite directions, place valve processing part between two activity pincers bodies 6 during suitable distance, continue to wave handle 12 to the tight state of clamp, use the drill bit processing, after the operation finishes, unscrew two activity pincers bodies 6, take out valve spare part. When a sensitive part of a valve core of the valve needs to be clamped, a soft cushion layer needs to be installed, a bolt or an iron wire and the like penetrate through the clamp body installation hole 9, and the soft cushion layer is additionally arranged on a jaw of the movable clamp body to carry out next operation. .

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
