Problems solved by technology

The cutting of blanks in the traditional valve production process requires one person to operate a cutting machine, which requires manual loading and unloading by workers. The labor intensity is high, the productivity is low, and the output per shift is very low. The processing quality is limited by the technical level of the workers, and the processing accuracy is low. The quality is difficult to guarantee, and the product cost is high, which affects the economic benefits of the enterprise

Embodiment 1

[0035] Embodiment 1: A numerically controlled valve automatic cutting machine for cutting and processing the total length of the valve according to the present invention, its structure is as follows figure 1 , 2 , including at least a positioning mechanism 81 installed on the machine bed 86, a headstock 82, a tool rest mechanism 83, a pushing mechanism 84 and a numerical control electric box 85, and the feeding mechanism 80 is installed on the bracket of the positioning mechanism and the headstock spindle On the seat; a three-phase asynchronous motor 1 is also installed in the bed of the machine tool.

[0036] see image 3 , the feeding mechanism is composed of a feeding frame, a valve feeder and a distribution frame, the upper and lower bars 6 of the feeding frame are installed on the arc-shaped plate 8, and the arc-shaped plate and the feeding arc-shaped frame 7 are fixed on the lower bottom plate 2. The screw seat 4 and the screw seat 5 are installed on the upper and lowe...

Embodiment 2

[0041] Embodiment 2: A kind of valve L of the present invention is used 校 Numerical control type valve automatic cutting machine for fixed size grooving, see Figure 8 , the rigid ball seat rotating member installed in the middle of the positioning spindle of the cutting machine of embodiment 1 is replaced with a flexible ball seat rotating member, that is, a coupling sleeve 75, a flexible ball seat spring 76, a retaining ring 77, and a ball seat type coupling block are installed. 78. The flexible ball seat rotating member composed of steel ball 79, together with the mandrel 34 at one end of the positioning main shaft, the small spring 32 and the positioning claw 33 constitute a flexible ball seat rotary positioning head, and the piston rod of the QGB63X160 standard cylinder 27 is installed on the ball seat On the type coupling block 78, the ball seat type coupling block and the positioning main shaft are connected together to move forward and backward; at the same time, the c...

Embodiment 3

[0042] Embodiment 3: apply the valve automatic cutting machine of the present invention of embodiment 1 on the production line, its working process is:

[0043] 1. Before starting the machine, when it is necessary to change the processed valve model, adjust the position of the loading rack by adjusting the waist hole; replace the three-lobed clamp block 48 in the combined fixture; put the valve bar material to be processed into the loading rack In the upper and lower sliding rods 6, the air valve automatically moves to the front of the distribution cylinder 22 in the inclined loading rack slide rod by its own weight;

[0044] 2. Turn on the switch of the cutting machine, and turn on each motor through the numerical control electric box. Adjust the working parameters according to the needs of the processed products: by adjusting the knob, the automatic switch will be adjusted and converted into an automatic cycle;

[0045] 3. The air valves are released one by one on the feedi...

Abstract

The invention relates to a full-automatic cutting machine of numerical controlled valve, which comprises a machine body, a feeding mechanism, a positioning mechanism, a geared head, a knife rest mechanism, a pushing mechanism and a numerical controlled electric box. The positioning mechanism utilizes a rigid ball base rotary positioning head and a positioning fixture at the end face of a valve disk part in the geared head to realize the full length cutting processing of the valve, and utilizes a flexible ball base rotary positioning head and a positioning fixture at the conical surface of the valve disk part in the geared head to realize the L-check size grooving processing of the valve. The rigid and flexible ball base rotary positioning heads overcome friction between workpieces and a positioner, eliminate the influences of the flat beat of the valve on positioning precision and the length precision of the processed valve reaches + / - 0.025mm. The cutting machine has simple structure, convenient operation and high full-automatic processing efficiency, is applicable to the full length cutting and grooving of the valve, and can be expanded to use the conical surface of the valve to position and process a sandwich groove of a lock and chamfer the end face of a valve rod; therefore, the full-automatic cutting machine has a wide application prospect.

Description

technical field [0001] The present invention relates to a numerically controlled automatic cutting machine for valves, in particular to a positioning fixture designed with a rigid and flexible ball seat rotating positioning head, and adopting two positioning fixtures: Realize valve overall length cutting process and valve L 校 CNC valve automatic cutting machine for size grooving. Background technique [0002] The valve is an important moving part in the valve train of an internal combustion engine, and the market demand is very large. The cutting of blanks in the traditional valve production process requires one person to operate a cutting machine, which requires manual loading and unloading by workers. The labor intensity is high, the productivity is low, and the output per shift is very low. The processing quality is limited by the technical level of the workers, and the processing accuracy is low. The quality is difficult to guarantee, and the product cost is high, whic...
