Abstract

The utility model relates to an improved tool bit of an automatic carving machine controlled by a computer, which is mainly composed of an air compressing main shaft, a front guide sleeve, a front fixing cylinder and a back fixing cylinder, wherein the air compressing main shaft can be stretched in the front and the back fixing cylinders. When the tool bit is fixed on a tool bit seat, a cutter at the front end of the air compressing main shaft can be used for carrying out carving work to a carved article. The front guide sleeve of the utility model is abutted on the surface of the carved article. A protruded cutter at the front end of the front guide sleeve carves the carved article to form a required groove. Because the air compressing main shaft has retractility, the air compressing main shaft can rise and fall following the arc of the surface of the carved object. Thus, very complex computer setting steps can be omitted and carving articles with superior quality can be obtained.

Description

The automatic engraving machine cutter head of improved computer

The utility model relates to the automatic engraving machine cutter head of a kind of computer, particularly relates to a kind ofly having Telescopic and can simplifying the cutter head that the automatic engraving machine of computer is set step.

With reference to figure 1, the board 10 of the general automatic engraving machine of computer is provided with horizontal slide rail 11 and vertical slide rail 12, and vertical slide rail 12 is provided with tool tip 13 and is used for fixing engraving cutter head 14; The below of engraving cutter head 14 is provided with anchor clamps and is used to grip carved object, so that engraving cutter head 14 is successfully carved operation to carved object.The general automatic engraving machine of computer can be carved on the surface of carved object and establish the groove (as the dimpled grain of golf clubs head batting surface) with appropriate depth, in computer program, set its stroke before the operation, with the shift motion of control tool tip 13 on horizontal slide rail 11 and vertical slide rail 12, and the depth of groove should be identical, can guarantee the quality of object.The engraving cutter head 14 of the automatic engraving machine of above-mentioned computer is fixed on the tool tip 13, and graver itself there is no flexible up and down function, thereby make the automatic engraving machine of computer when establishing flat surface (as the striking surface of golf iron) quarter, it is comparatively simple and easy that its computer is set step; But when Ruo Ke establishes curved surfaces (as the striking surface of golf rod), the step that its computer is set then must be set up very complicated setting value again, so that engraving cutter head 14 shift motions meet curved surfaces, the time compole that it spent is long, so very big to overall operation flow process and influence in man-hour.

The purpose of this utility model promptly is the automatic engraving machine cutter head structure of computer is improved, and makes it to have Telescopic and and then simplifies the setting step of the automatic engraving machine of computer.

To achieve these goals, the utility model adopts the compression spring and feather key can stretch the pneumatics main shaft in forward and backward stationary magazine creel and be provided with at the front end of pneumatics main shaft and be used to the preceding guide pin bushing of carved object surface and protruding dew cutter of conflicting, thus make the pneumatics main shaft can be with carved object surface arc lifting and omit the very computer setting step of complexity whereby.Below in conjunction with specific embodiment technical characterictic of the present utility model is described in further detail.

Fig. 1 is the planar structure schematic diagram of the automatic engraving machine of computer;

Fig. 2 is a planar structure schematic diagram of the present utility model;

Fig. 3 is an engraving action schematic diagram of the present utility model.

With reference to figure 2, the utility model mainly is made of pneumatics main shaft 20, preceding guide pin bushing 30, preceding stationary magazine creel 40 and back stationary magazine creel 50 and is fixed on the tool tip 13.

Pneumatics main shaft 20 is a circular cylinder body, and its front-end edge is provided with adjusts screw thread 21, adjusts screw thread 21 front ends and then is provided with the fixed claw 23 that utilizes air pressure clamped tool 22, and its rear end then locks a slip fixed cover 24, and slip fixed cover 24 is provided with guide groove 25.

The top, front side of preceding guide pin bushing 30 has a breach 31 and can supply the protruding dew of cutter of pneumatics main shaft 20 front ends, and preceding guide pin bushing 30 is set on the adjustment lining 32 and utilize set bolt 33 fixing, the inner hole wall of adjusting lining 32 is provided with screw thread and whereby with preceding guide pin bushing 30 and adjust the front end that lining 32 is fixed in pneumatics main shaft 20, utilizes the screw thread of adjusting lining 32 can adjust the distances of guide pin bushing 30 before cutter 22 protruding being exposed to.

Preceding stationary magazine creel 40 is the hollow circular cylindrical shell, and its cylinder inboard wall has can be for the slide bushing 41 of sliding friction, the rear end face of stationary magazine creel 40 before pneumatics main shaft 20 is placed through wherein and makes the slip fixed cover 24 of pneumatics main shaft 20 rear axles to be resisted against.

Back stationary magazine creel 50 is the hollow circular cylindrical shell, the rear side of stationary magazine creel 40 before its front side end is located at by screw fastening, back stationary magazine creel 50 inside are provided with a feather key 51 and a compression spring 52, this compression spring 52 relies on the slip fixed cover 24 of pneumatics main shaft 20, feather key 51 then can supply guide groove 25 slippages of slip fixed cover 24, thereby pneumatics main shaft 20 can be stretched in preceding stationary magazine creel 40 and back stationary magazine creel 50.

When the engraving cutter head of said structure is fixed in tool tip 13, can utilize 22 pairs of carved objects of cutter of pneumatics main shaft 20 front ends to impose the engraving operation, its preceding guide pin bushing 30 contacts at the carved object surface, and the cutter 22 of the protruding dew of preceding guide pin bushing 30 front ends is then established carved object quarter, makes it form groove.Because pneumatics main shaft 20 itself has scalability, thereby can make pneumatics main shaft 20 lifting (as shown in Figure 3) with the arc on carved object surface, can omit very complicated computer whereby and set step and can obtain the superior engraving article of quality.

Reach embodiment shown in the drawings in sum as can be known, the utility model really can make the engraving cutter head have Telescopic, and then can simplify the setting step of the automatic engraving machine of computer.
