Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] By providing a screw cutting and processing fixture in the embodiments of the present application, the problems are solved that since the existing turning fixtures only have a clamping function and lack positioning and guiding functions, an additional propulsion mechanism for positioning and guiding is required to push the fixture near the cutting tool for processing and cutting, and fast loading and unloading cannot be achieved, resulting in low processing efficiency.

[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0023] The embodiments of the present utility model disclose a screw cutting and processing fixture.

[0024] According to the attached Figure 1-6As shown in the figure, it includes a clamping mechanism 1. The clamping mechanism 1 includes a main seat 11, a rotary clamping member 12 and a positioning and rotating member 13. The rotary clamping member 12 is rotatably connected within the main seat 11, and the positioning and rotating member 13 is fixedly connected to the main seat 11. A servo motor 114 is provided within the main seat 11. The rotary clamping member 12 includes a runner 121 and an electric chuck 122. The electric chuck 122 is movably clamped within the runner 121. The runner 121 is fixedly connected to the power output end of the servo motor 114. The bottom of the electric chuck 122 is movably clamped to the front end of the positioning and rotating member 13. The main seat 11 serves as the main body of the fixture, fixing the rotary clamping member 12 and the positioning and rotating member 13. During use, the electric chuck 122 fixedly clamps the screw to be processed at the bottom of the runner 121. As the runner 121 rotates to the top, it is clamped by the positioning and rotating member 13 at the back and rotated and pushed into the processing area in front of the runner 121 for cutting processing. After completion, the positioning and rotating member 13 retracts and clamps the electric chuck 122 back into the runner 121. As the runner 121 rotates back to the bottom, the clamping member of the electric chuck 122 retracts, and the processed screw drops under the action of gravity. Then, the feeding mechanism feeds the screw to be processed into the electric chuck 122 to complete the cycle. Through the setting of the runner 121, rapid loading and unloading are achieved, improving the production and processing efficiency.

[0025] The main seat 11 further includes an arc-shaped base 111, a bracket 112 and a triangular seat 113. The bracket 112 and the triangular seat 113 are fixedly connected to the top of the arc-shaped base 111. The servo motor 114 is fixedly connected within the bracket 112. The positioning and rotating member 13 is arranged on the triangular seat 113. The arc-shaped base 111 fixes the bracket 112 and the triangular seat 113. The arc design of the arc-shaped base 111 allows the runner 121 to pass through.

[0026] An outlet 116 is provided within the arc-shaped base 111, and a feeding port 115 is provided within the bracket 112. The design of the outlet 116 enables the processed finished products dropped at the bottom of the runner 121 to be directly sent to other equipment below the outlet 116, such as a conveyor belt, etc., for other processing in the next area, improving the unloading efficiency. The feeding port 115 is directly opposite the bottom of the runner 121. When the electric chuck 122 releases the processed finished product, with the help of other feeding mechanisms, a new screw to be processed is directly placed within the electric chuck 122, achieving the purpose of rapid feeding and improving the processing efficiency.

[0027] A telescopic cylinder 131 is provided within the positioning and rotating member 13. A telescopic main rod 1311 is slidably connected within the telescopic cylinder 131. An ear 1312 is fixedly connected to the outer surface of the telescopic cylinder 131. The ear 1312 is fixedly connected to the triangular seat 113 by bolts. Through the telescopic cylinder 131, this fixture can push the screw to be processed into the processing and cutting area without other auxiliary equipment.

[0028] A small motor 132 is fixedly connected inside the front end of the telescopic main rod 1311. The power output end of the small motor 132 is fixedly connected with a magnetic attraction special-shaped card connector 1321. The small motor 132 is fixedly connected inside the telescopic main rod 1311 and is connected to the magnetic attraction special-shaped card connector 1321 through the output shaft of the motor.

[0029] A special-shaped groove 1221 is opened at the bottom end of the electric chuck 122. The magnetic attraction special-shaped card connector 1321 is movably clamped inside the special-shaped groove 1221. During use, the magnetic attraction special-shaped card connector 1321 is magnetically clamped inside the special-shaped groove 1221 and advances to the processing area under the push of the telescopic main rod 1311, and then rotates and cuts under the power of the small motor 132 to complete the processing.
