[0018] Please see Figure 1 and Figure 2 A clamping device for lathe machining includes a base 10, a placement table 20 mounted on the base 10 for placing the workpiece to be processed, a movable seat 40 arranged in a cross shape on the four sides of the placement table 20, and a clamping assembly 30 mounted on the movable seat 40 for clamping the workpiece on the placement table 20. The clamping assembly 30 includes an arc-shaped clamping plate 301 and a square clamping plate 302 mounted on the movable seat 40 and staggered in the vertical direction, and a first drive unit connected to the arc-shaped clamping plate 301 and the square clamping plate 302 for driving the arc-shaped clamping plate 301 or the square clamping plate 302 to move toward the center of the placement table 20 to clamp the workpiece to be processed.

[0019] Specifically, during operation, the base 10 is mounted on the machine tool, and the workpiece to be processed is placed on the placement table 20. If the workpiece is round, the first drive unit drives the arc-shaped clamping plate 301 to move toward the center of the placement table 20 to clamp the workpiece. At the same time, since the four moving seats 40 are arranged in a "+" shape, the sides of the workpiece can be effectively clamped, thus ensuring the stability during clamping. In addition, since the arc-shaped clamping plate 301 and the square clamping plate 302 are staggered, interference between the arc-shaped clamping plate 301 and the directional clamping plate during movement is avoided. The same principle applies when the workpiece is square, so it will not be elaborated further.

[0020] The present invention relates to a clamping device for lathe machining. Through the arrangement of the base 10, the placement table 20, the movable seat 40 and the clamping assembly 30, the clamping effect of the workpiece is good, which facilitates the stable machining of the workpiece by the machine tool and thus improves the machining effect. At the same time, through the arrangement of the arc-shaped clamping plate 301 and the square clamping plate 302 in the clamping assembly 30, it is convenient to clamp different types of workpieces, which greatly improves the practicality of the clamping device and thus improves the user experience.

[0021] In one specific embodiment, the first drive unit includes a first lead screw 303, a second lead screw 304, a first connecting rod 305, a second connecting rod 306, and a power module; the first lead screw 303 and the second lead screw 304 are mounted side by side in the movable seat 40, and the first lead screw 303 and the second lead screw 304 have reversed first threaded sections; the first connecting rod 305 is mounted above the first lead screw 303 and connected to the first lead screw 303, and is used to move along the first lead screw 303 when the first lead screw 303 rotates. The first connecting rod 305 moves along the axial direction, and the side of the first connecting rod 305 is connected to the end of the square clamping plate 302; the second connecting rod 306 is installed above the second lead screw 304 and connected to the second lead screw 304, and is used to move along the axial direction of the second lead screw 304 when the second lead screw 304 rotates, and the side of the second connecting rod 306 is connected to the end of the arc-shaped clamping plate 301; the power module is connected to the first lead screw 303 and the second lead screw 304, and is used to drive the first lead screw 303 and the second lead screw 304 to rotate synchronously.

[0022] Specifically, during operation, the workpiece to be processed is placed on the placement table 20. When the workpiece is square, the power module drives the first lead screw 303 and the second lead screw 304 to rotate synchronously. At this time, the first lead screw 303 drives the square clamping plate 302 to move toward the workpiece through the first connecting rod 305, thereby clamping and fixing the workpiece. Since the first thread sections of the first lead screw 303 and the second lead screw 304 are in opposite directions, when the arc-shaped clamping plate 301 is close to the workpiece for clamping, the arc-shaped clamping plate 301 is away from the workpiece, thus facilitating the clamping of the square workpiece. When the workpiece to be processed is round, the same principle applies, which will not be elaborated here.

[0023] In one specific embodiment, the power module includes a transmission wheel 307 mounted on the ends of the first lead screw 303 and the second lead screw 304, a transmission belt 308 connected to the two transmission wheels 307, and a first motor 309 connected to one of the transmission wheels 307 for driving the transmission wheel 307 to rotate. Specifically, during operation, the first motor 309 drives the transmission wheel 307 connected to it to rotate, and the transmission belt 308 simultaneously enables the first lead screw 303 and the second lead screw 304 to rotate synchronously.

[0024] In one specific embodiment, the upper part of the base 10 is provided with a slide rail 101; the slide rail 101 is provided on the four sides of the placement table 20; the movable seats 40 are slidably mounted on the slide rail 101; the clamping assembly 30 also includes a second drive unit installed inside the base 10 for driving the four movable seats 40 to move relative to each other on the slide rail 101. Specifically, during operation, the workpiece to be processed is placed on the placement table 20. At this time, the second drive unit drives the four movable seats 40 to move along the slide rail 101 toward the placement table 20, thereby performing an initial movement of the movable seats 40 to facilitate subsequent clamping of the workpiece by the arc-shaped clamping plate or the square clamping plate.

[0025] In one specific embodiment, the second drive unit includes a third lead screw 310, a fourth lead screw 311, a first connecting block 312, a second connecting block 313, a second motor 314, and a third motor 315. The third lead screw 310 is installed inside the base 10 and is parallel to one of the pairs of opposing movable seats 40, and the third lead screw 310 has two opposite second threaded sections corresponding to the two movable seats 40. The fourth lead screw 311 is installed inside the base 10 and is parallel to another pair of opposing movable seats 40, and the fourth lead screw 311 has two opposite second threaded sections corresponding to the two movable seats 40. The movable seat 40 has two opposite third threaded sections; two first connecting blocks 312 are provided, each mounted on one of the two second threaded sections and connected to the two opposite movable seats 40; two second connecting blocks 313 are provided, each mounted on one of the two third threaded sections and connected to the two opposite movable seats 40; a second motor 314 is connected to a third lead screw 310 to drive the third lead screw 310 to rotate; a third motor 315 is connected to a fourth lead screw 311 to drive the fourth lead screw 311 to rotate. Specifically, during operation, the second motor 314 or the third motor 315 drives the third lead screw 310 or the fourth lead screw 311 to rotate. Due to the arrangement of the two opposite second or third threaded sections, the two first connecting blocks 312 or the second connecting blocks 313 can move closer or further apart as needed, thereby causing the movable seats 40 connected to them to move closer or further apart, thus facilitating the clamping of the workpiece by the square clamping plate 302 or the circular clamping plate.

[0026] In one specific embodiment, the base 10 is provided with a clearance groove 102 for the first connecting block or the second connecting block to move.

[0027] The present invention relates to a clamping device for lathe machining. Through the arrangement of the base 10, the placement table 20, the movable seat 40 and the clamping assembly 30, the clamping effect of the workpiece is good, which facilitates the stable machining of the workpiece by the machine tool and thus improves the machining effect. At the same time, through the arrangement of the arc-shaped clamping plate 301 and the square clamping plate 302 in the clamping assembly 30, it is convenient to clamp different types of workpieces, which greatly improves the practicality of the clamping device and thus improves the user experience.

[0028] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
