In this way, the utility model discloses connect conveniently, the change of the drill bit of being convenient for, simple structure is novel moreover, long service life.

Description

First three-jaw adapter of valve upper cover processing line

Technical field

This utility model is related to field of machinery automation, more particularly to a kind of one or three ZHUANLIAN of valve upper cover processing line Connect device.

Background technology

Bit connectors are to connect together a securing member being called joint with drill bit, and existing face milling cutters connect Device is not easy to the replacing of drill bit, connects also inconvenient, and service life is shorter, is not suitable for life-time service, this has resulted in life Produce high cost.

Utility model content

This utility model is mainly solving the technical problems that provide a kind of simply novel valve upper cover processing line of structure First three-jaw adapter.

For solving above-mentioned technical problem, the technical scheme that this utility model adopts is：A kind of valve upper cover is provided to add First three-jaw adapter of work line, the first three-jaw adapter of this valve upper cover processing line includes body and lower body, lower Body is downward-sloping cone, and upper body and lower body are provided with the drill bit installing hole of concentric, the lower surface position of upper body Position outside drill bit installing hole is provided with the axis of guide mounting groove of trisection, is mounted on rotating in three axis of guide mounting grooves The axis of guide, three rotary steering axles are mounted on rotatable drill bit clamping block, and upper body is provided with and drill bit clamping block pair The chute answered, chute leads to the drill bit installing hole of body, and three pieces of drill bit clamping blocks all can slide in the chute on upper body, The lateral surface of three pieces of drill bit clamping blocks is fitted with the inner cavity surface of lower body, and the first three-jaw adapter also includes clamping screw, upper Body and lower body are locked by clamping screw.

The beneficial effects of the utility model are：A kind of first three-jaw adapter of this utility model valve upper cover processing line, First three-jaw adapter of this valve upper cover processing line is easy to connect, is easy to the replacing of drill bit, and structure is simply novel, uses Life-span length.

Brief description

Fig. 1 is the structural representation of the first three-jaw adapter of this utility model valve upper cover processing line；

Fig. 2 is the exploded perspective view of the first three-jaw adapter of this utility model valve upper cover processing line.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model preferred embodiment is described in detail, so that the advantage of utility model and spy Levy and can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made with apparent clear and definite boundary Fixed.

Refer to Fig. 1 and Fig. 2, this utility model embodiment includes：

A kind of first three-jaw adapter of valve upper cover processing line, the first three-jaw adapter bag of this valve upper cover processing line Include body 151130 and lower body 151131, lower body 151131 is downward-sloping cone, upper body 151130 and under Body 151131 is provided with the drill bit installing hole of concentric, and the lower surface of upper body 151130 is located at the position outside drill bit installing hole Install the axis of guide mounting groove of trisection, in three axis of guide mounting grooves, be mounted on rotary steering axle 151132, three rotations Turn and rotatable drill bit clamping block 151133 is mounted on the axis of guide 151132, upper body 151130 is provided with and drill bit clamping The corresponding chute of block 151133, chute leads to the drill bit installing hole of body 151130, three pieces of drill bit clamping blocks 151133 Slide in the chute on upper body 151130, the inner chamber of the lateral surface of three pieces of drill bit clamping blocks 151133 and lower body 151131 Fit in face, the first three-jaw adapter 15113 also includes clamping screw 151134, and upper body 151130 and lower body 151131 pass through Clamping screw 151134 is locked.

During utility model works, manual adjustment clamping screw 151134 makes lower body 151131 body 151130 upwards Draw close, body 151130 draws close drive drill bit clamping block 151133 along 151132 turns of rotary steering axle to lower body 151131 upwards Downwards by screw tap clamping, when changing screw tap, manual adjustment clamping screw 151134 makes for the upper end making drill bit clamping block 151133 Body 151131 slide downward must be descended, lower body 151131 slide downward drives drill bit clamping block 151133 along rotary steering axle Screw tap is unclamped by 151132 turns of upper ends making drill bit clamping block 151133 upwards.
