[0018] Refer to Figures 1 to 4 As shown in the figure, the utility model provides a telescopic turning tool rapid positioning device, including: a positioning base 1, a positioning frame 2 and a turning tool body 3. The right side of the positioning base 1 is connected with the positioning frame 2 through a rotating block 12, and the front end of the positioning frame 2 is provided with the turning tool body 3.

[0019] The right end of the rotating block 12 is connected with an electric slide 21 through an electric push rod 13. The electric slide 21 is slidably connected with the positioning frame 2 on the right side. The right side of the positioning frame 2 is connected with an upper pressing plate 4 and a lower pressing plate 41 through a lead screw 23. The inner side of the upper pressing plate 4 is embedded and fixed with a spacing sensor 43. A side positioning plate 5 is arranged between the upper pressing plate 4 and the lower pressing plate 41. The front side of the side positioning plate 5 is welded with an L-shaped clamping plate 51, and a distance sensor 52 is installed on the lower surface of the L-shaped clamping plate 51.

[0020] When machining a columnar cutting part, first, the electric push rod 13 pushes the positioning frame 2 to move to the right, and then the electric slide 21 drives the positioning frame 2 to move backward, so that the L-shaped clamping plate 51 on the front side of the side positioning plate 5 fits on the front surface of the columnar cutting part. At this time, the side end of the side positioning plate 5 also fits with the side surface of the columnar cutting part. Then, the upper pressing plate 4 and the lower pressing plate 41 move synchronously towards the middle to fit with the upper and lower surfaces of the columnar cutting part. After the cutting position of the turning tool body 3 is measured by the spacing sensor 43, the positioner 24 and the distance sensor 53, the cutting mechanism drives the turning tool body 3 to move to the measured position. When the turning tool body 3 continuously approaches the positioning frame 2, the rotating block 12 drives the positioning frame 2 to turn to the other side to avoid hindering the machining of the moving turning tool body 3 and the columnar cutting part.

[0021] In this embodiment, a tool mounting piece 31 is screwed on the surface of the turning tool body 3, and a columnar cutting part is fitted between the upper pressing plate 4 and the lower pressing plate 41; and a workpiece fixture 6 is clamped and connected to the rear end of the columnar cutting part. A positioner 24 is embedded and installed at the front end of the positioning frame 2, and a receiver 32 is fixed on the upper surface of the tool mounting piece 31; and the positioner 24 and the receiver 32 are flush with each other correspondingly.

[0022] As a preferred embodiment, the turning tool body 3 is connected to the cutting mechanism through the tool mounting member 31, so that the cutting mechanism drives the turning tool body 3 to move towards the cylindrical cutting part clamped by the tool mounting member 31. The positioner 24 facilitates positioning the side cutting position of the turning tool body 3, so that the blade end of the turning tool body 3 is consistent with the side position of the turning tool body 3.

[0023] In this embodiment, a first motor 11 is fixed to the rear side surface of the positioning base 1, a rotating block 12 is axially connected to the front end of the first motor 11, and a protective plate 25 is fixed to the upper and lower end surfaces of the electric slide table 21.

[0024] As a preferred embodiment, the first motor 11 drives the rotating block 12 to perform a 180-degree flip, so that the positioning frame 2 moves away from or closer to the cylindrical cutting part clamped by the tool mounting member 31. The protective plate 25 facilitates blocking the splashing of waste chips during cutting.

[0025] In this embodiment, a second motor 22 is fixed to the upper end of the positioning frame 2, and two sets of lead screws 23 are installed in the right slot of the positioning frame 2; and the upper ends of the lead screws 23 are connected to the second motor 22. The left ends of the upper pressing plate 4 and the lower pressing plate 41 are connected to the lead screws 23 through the driving block 42, and a side positioning plate 5 is fixed to the right side surface of the positioning frame 2; and the right end of the side positioning plate 5 is arc-shaped.

[0026] As a preferred embodiment, the second motor 22 drives the two sets of butt-jointed lead screws 23 to rotate synchronously, so that the lead screws 23 convert the rotational motion into a linear motion, driving the upper pressing plate 4 and the lower pressing plate 41 to perform reverse synchronous motion, so that the upper pressing plate 4 and the lower pressing plate 41 are attached to the upper and lower surfaces of the cylindrical cutting part, facilitating the measurement of the diameter of the cylindrical cutting part. The arc-shaped side end of the side positioning plate 5 is used to fit with the side of the cylindrical cutting part, facilitating the position where the turning tool body 3 cuts from the side.

[0027] In this embodiment, the positioning base 1, the rotating block 12, the electric push rod 13 and the electric slide table 21 constitute a telescopic adjustment structure of the positioning frame 2.

[0028] As a preferred embodiment, the telescopic adjustment structure of the positioning frame 2 facilitates adjusting the position of the positioning frame 2, so that the positioning frame 2 makes the pressing plate and the side positioning plate 5 contact the cylindrical cutting part, facilitating the rapid flipping and retraction of the positioning device when the turning tool moves for cutting, preventing the cutting waste chips from splashing in and affecting the normal operation and measurement of the positioning device, and ensuring the accuracy of the turning tool positioning device.

[0029] The retractable turning tool rapid positioning device of the utility model can effectively solve the problem that the sliding chute and the lead screw of the positioning component on the fixed seat in the prior art are easily affected by the falling cutting waste chips and affect the normal positioning adjustment, facilitate the determination of the cutting position of the fixture of the clamped workpiece, and at the same time, when the turning tool moves for cutting, the positioning device quickly flips and retracts, preventing the cutting waste chips from splashing in and affecting the normal operation and determination of the positioning device, ensuring the accuracy of the turning tool positioning device, and is applicable to the retractable turning tool rapid positioning device.
