Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

A milling and drilling machine with stable clamping is shown in figures 1 to 5, and comprises a milling and drilling machine 1, wherein the milling and drilling machine 1 comprises a workbench 2, a bottom groove 4 is formed in the surface of the workbench 2, a threaded screw rod 5 is rotatably connected inside the bottom groove 4, one end of the threaded screw rod 5 penetrates through the bottom groove 4 and extends out of the bottom groove 4, an L-shaped rotating rod 10 is arranged at one end of the threaded screw rod 5 extending out of the bottom groove 4, a clamping piece 6 made of hard alloy is connected with one end of the threaded screw rod 5 positioned inside the bottom groove 4 in a threaded manner, the clamping piece 6 is slidably connected inside the bottom groove 4, a limiting block 3 which is parallel to and opposite to the clamping piece 6 is arranged on the surface of the workbench 2, sawtooth-shaped anti-skid grains 9 are arranged on one surface of the clamping piece 6 opposite to the limiting block 3, sliding grooves 7 are formed in two side walls of the bottom groove 4, sliding blocks 8 for being clamped into the sliding grooves 7 are arranged on two sides of, 11 inside sliding connection of sliding tray has slide 12, and 12 one end sliding connection of slide is inside 11 sliding tray, and first open slot 13 has all been seted up to the other end and 6 fixed connection of holder, and 3 both sides of stopper have, and the inside articulated screw rod 14 that has of first

open slot

13, and 6 both sides of holder are offered and are used for the second open slot 15 that 14 cards of screw rod are gone into, and threaded connection has nut 16 on the screw rod 14, is provided with knob 17 on the 16 periphery walls of nut, and the 16 diameters of nut are greater than the 15 diameters of second open slot.

When centre gripping work piece, put into the work piece earlier between stopper 3 and the holder 6, rotate the part that screw lead screw 5 stretches out kerve 4 afterwards, whole screw lead screw 5 begins to rotate, thereby drive the motion of holder 6, because kerve 4 is spacing to holder 6, make holder 6 can only move in kerve 4 inside along screw lead screw 5's axial direction, holder 6 draws close to stopper 3 gradually, after holder 6 presss from both sides the work piece through the cooperation with stopper 3, the centre gripping of having just accomplished the work piece is fixed, the operation is thus simple, connect stably, be difficult for droing, the work piece is difficult for taking place to rock man-hour, the machining precision of work piece has been promoted greatly.

Owing to be provided with spout 7 and slider 8, realized holder 6 at the inside sliding connection of kerve 4, and spacing through spout 7 to slider 8 for holder 6 is difficult for the incline at the slip in-process, makes holder 6 more smooth and easy at the slip in-process, and the centre gripping is more accurate.

Owing to be provided with the anti-skidding line 9 that is the cockscomb structure for can receive the extrusion of anti-skidding line 9 point face when the work piece is pressed from both sides tightly, thereby greatly increased the coefficient of friction on stopper 3 and the 6 surfaces of holder, thereby make the card that the work piece can be more firm between stopper 3 and holder 6, and then make the machining precision of work piece obtain further promotion.

Due to the arrangement of the rotating rod 10, the arrangement of the rotating rod 10 changes the force application point when the threaded screw rod 5 is rotated, so that the operation of enabling the clamping piece 6 to perform axial movement by rotating the rotating rod 10 is more convenient and labor-saving.

Owing to be provided with sliding tray 11 and slide 12, slide 12's setting can be kept apart the waste material and slide 12 on the surface, has avoided in the course of working of work piece, thereby the waste material that produces during add also can influence the rotation of screw lead screw 5 when making the inconvenient clearance of waste material inside can dropping into kerve 4, leads to the condition emergence of the unable smooth and easy work piece centre gripping of holder 6.

Due to the fact that the first open slot 13 and the second open slot 15 are arranged, the screw 14 is hinged inside the first open slot 13, after the clamping piece 6 is matched with the limiting block 3 to clamp a workpiece, the screw 14 is rotated to enable the screw 14 to enter the second open slot 15, then the nut 16 is screwed, the clamping piece 6 further clamps the workpiece, the fixing capacity of the workpiece is greatly improved due to the double-fixing structure, and the workpiece is clamped more stably.

Due to the arrangement of the knob 17, the force application point when the nut 16 is rotated is changed by the arrangement of the knob 17, so that the operation of clamping the clamping piece 6 by rotating the nut 16 is more convenient and labor-saving.

Because the holder 6 is made of cemented carbide, the cemented carbide has extremely high hardness and wear resistance, so that the holder 6 has high hardness and excellent wear resistance, is not easy to wear, and prolongs the service life of the holder 6.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
