[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] As shown in Figures 1 to 5, the present invention provides an engine valve processing fixture, including a valve feeding assembly 1, a valve discharging assembly 2, a valve continuous transfer assembly 3, and a valve positioning and clamping assembly 4. The valve continuous transfer assembly 3 is fixedly connected inside the valve positioning and clamping assembly 4, and the valve positioning and clamping assembly 4 is located between the valve feeding assembly 1 and the valve discharging assembly 2.

[0023] In use, the stamped valve is conveyed through the valve feeding assembly 1, and the valve is transferred through the valve continuous transfer assembly 3 so that the valve enters the processing position and the processed valve is sent to the valve discharge assembly 2 for discharge.

[0024] Both the valve feeding assembly 1 and the valve discharging assembly 2 are composed of a support frame 5, a conveyor belt 6, a servo motor 7 and several valve positioning supports 8. The conveyor belt 6 is rotatably connected to the inside of the support frame 5. The servo motor 7 is fixedly connected to one end of the side of the support frame 5 and connected to the conveyor belt 6. The valve positioning supports 8 are symmetrically connected to both sides of the outer surface of the conveyor belt 6.

[0025] Servo motor 7 can drive the conveyor belt 6 to move, and valve positioning support 8 can limit the valve and improve the valve stability.

[0026] The valve continuous transfer assembly 3 consists of a strip-shaped housing 9, a second servo motor 10, a lead screw 11, a slider 12, a first cylinder 13, an I-shaped bracket 14, two second valve positioning supports 15, and two third valve positioning supports 16. The second servo motor 10 is fixedly connected to one end of the strip-shaped housing 9. The lead screw 11 is rotatably connected to the inside of the strip-shaped housing 9 and fixedly connected to the output shaft of the second servo motor 10. The slider 12 is slidably connected to the inside of the strip-shaped housing 9 and threadedly connected to the lead screw 11. The first cylinder 13 is fixedly connected to the top of the slider 12. The I-shaped bracket 14 is fixedly connected to the top of the first cylinder 13. The second valve positioning supports 15 and the third valve positioning supports 16 are respectively fixedly connected to the two ends of the I-shaped bracket 14.

[0027] When the valve on the valve feeding assembly 1 reaches position A in Figure 1, the servo motor 10, lead screw 11, and slider 12 drive the cylinder 13, I-beam bracket 14, valve positioning support 15, and valve positioning support 16 to move as a whole. This causes valve positioning support 15 to move to position A and be directly below the valve at that position. At this time, valve positioning support 16 moves to position C and is directly below the processed valve. Valve positioning supports 15 and 16 are offset from valve positioning support 8. The cylinder 13 drives the I-beam bracket 14, valve positioning support 15, and valve positioning support 16 to rise, causing valve positioning support 15 to contact the valve at position A and raise the valve to a certain height. Valve positioning support 16 then contacts the processed valve at position C and raises the valve. The valve rises, and then the servo motor 10, lead screw 11, and slider 12 drive the cylinder 13, I-shaped bracket 14, valve positioning support 15, and valve positioning support 16 to move as a whole, so that valve positioning support 15 moves to position C and valve positioning support 16 moves to position B. Then, the cylinder 13 drives the I-shaped bracket 14, valve positioning support 15, and valve positioning support 16 to move down, and the valve positioning clamping assembly 4 clamps the valve at position C. The valve on valve positioning support 16 then contacts the valve discharge assembly 2. Then, the cylinder 13 drives the I-shaped bracket 14, valve positioning support 15, and valve positioning support 16 to continue to move down, so that valve positioning support 15 and valve positioning support 16 separate from the two valves. Repeating the above steps can achieve continuous feeding and discharging.

[0028] The top of valve positioning support 18, valve positioning support 215 and valve positioning support 316 are all provided with arc-shaped positioning grooves 17, which can realize stable limiting of valve and improve valve stability.

[0029] The valve positioning clamping assembly 4 consists of an L-shaped support frame 18, a positioning clamp 19, a cylinder 20, a support plate 21, a servo motor 3 22, and a positioning clamp 23. The positioning clamp 19 is rotatably connected to the top of one side of the L-shaped support frame 18. The support plate 21 is connected to one end of the top of the L-shaped support frame 18 through the cylinder 20. The servo motor 3 22 is fixedly connected to the top of one side of the support plate 21. The positioning clamp 23 is rotatably connected to the top of the other side of the support plate 21 and is fixedly connected to the output shaft of the servo motor 3 22. A limiting groove 24 that is slidably connected to the support plate 21 is provided at one end of the top of the L-shaped support frame 18.

[0030] When the valve to be processed enters the position of the valve positioning and clamping assembly 4, the cylinder 20 drives the support plate 21 to move, and the valve is clamped by the positioning clamp 19 and the positioning clamp 23. The servo motor 3 22 can drive the positioning clamp 23 to rotate, which in turn drives the valve to rotate. At this time, the valve can be precision machined by the turning device or the grinding device.

[0031] In operation, the valve feeding assembly and valve discharging assembly, consisting of a support frame, conveyor belt, servo motor 1, and several valve positioning supports 1, can feed and discharge valves. The valve continuous transfer assembly, consisting of a strip-shaped housing, servo motor 2, lead screw, slider, cylinder 1, I-shaped bracket, two valve positioning supports 2 and two valve positioning supports 3, can transfer the valves on the valve feeding assembly to the processing position and send the processed valves into the valve discharging assembly for discharge. The valve positioning and clamping assembly, consisting of an L-shaped support frame, positioning clamp 1, cylinder 2, support plate, servo motor 3 and positioning clamp 2, can clamp and fix the valves, making it easy to turn or grind them using a turning or grinding device.
