Since objects need to be firmly clamped when they are processed by CNC lathes, and not all objects have tubular parts suitable for clamping, many objects cannot be processed by CNC lathes. The existing solution is to use a chuck to clamp the tooling first, and then load the object into the tooling, but it has the disadvantages of unstable installation, troublesome installation, and easy misalignment.

[0003] Therefore, the existing CNC lathe chuck needs to be further improved. Utility Model Content

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0023] like Figures 1 to 5A new type of CNC lathe chuck shown in the figure includes a chassis 1, a plurality of calipers 2 are arranged on the chassis 1, a toothed disc 3 connected to the calipers 2 is arranged in the chassis 1, and a driving member 4 that can rotate the toothed disc 3 is arranged in the chassis 1, a clamping member 1 5 and a clamping member 2 6 that can respectively clamp objects of different shapes are arranged in the caliper 2, and a switching structure 7 that allows the clamping member 1 5 and the clamping member 2 6 to be switched for use, and an electromagnetic locking device 8 that can lock the clamping member 1 5 and the clamping member 2 6 is also provided. The caliper is provided with a clamping member 1 and a clamping member 2 respectively, the clamping member 1 is used to clamp the disc-shaped and tubular object parts, and the clamping member 2 is used to clamp square objects and objects with two opposite sides parallel. These two clamping states can be switched by the switching structure and then locked by the electromagnetic locking device. The structure of the chassis, calipers, toothed disc, and driving member adopts the chuck structure in the existing technology, and the toothed disc is rotated by using a wrench to twist the driving member, and when the toothed disc rotates, each caliper on the chuck is driven to move closer to or away from each other.

[0024] The calipers 2 described in the utility model are provided with two and are symmetrically arranged. Two calipers can be provided to clamp disc-shaped, tubular objects or square objects, and objects with two pairs of parallel sides. Four calipers can be used according to actual conditions, which can be used to clamp long and square objects, which is more stable.

[0025] The caliper 2 of the utility model is provided with four clamping members 1 5 and two clamping members 2 6. The clamping members 1 5 are arranged at the four corners of the inner wall of the caliper 2, and the clamping members 2 6 are arranged vertically on both sides of the middle of the inner wall of the caliper 2. The clamping members 1 at the four corners can be connected with the parts of the disc-shaped or tubular objects so that they can be fixed at multiple points therein. The clamping members 2 arranged at the upper and lower sides of the middle can fit the wall of a square object or an object with two parallel sides. According to actual conditions, the clamping member 1 can also clamp an elliptical object with a regular shape.

[0026] The end of the clamping member 15 in the utility model is in an arc shape, so that multi-point pressing and fixing can be achieved when the disc-shaped or tubular object is pressed against it.

[0027] The clamping member 2 6 described in the utility model is a square plate body, which can achieve full surface close contact when it is close to the wall surface of a square object or an object with two parallel sides. Anti-slip lines can also be set on the outer wall surface of the square plate body for contacting the object to increase friction.

[0028] The switching structure 7 in the utility model includes a slope surface 71 arranged at the outer ends of the clamping member 1 5 and the clamping member 2 6, and two slide grooves 72 arranged up and down are arranged in the caliper 2, and a slide rod 73 that can press the slope surface 71 is arranged in the slide groove 72. There is a slide rod in each of the two slide grooves, and each slide rod can contact the clamping member 1 or the clamping member 2 respectively, and through the up and down linear movement of the slide rod, it can contact the slope surface on the clamping member 1 or the clamping member 2 respectively, and squeeze the corresponding clamping member 1 or the clamping member 2 to the front end through the slope surface.

[0029] The switching structure 7 in the utility model also includes a linear groove 74 symmetrically arranged on the left and right sides of the caliper 2, a linear slider 75 is arranged in the linear groove 74, the linear slider 75 and the two slide bars 73 are connected by a connecting rod 76, and an electric push rod 77 that can push the linear slider 75 to move is arranged in the linear groove 74. The up and down linear movement of the slide bar can be realized by numerical control to extend or retract the electric push rod. When the electric push rod is extended, the extended end pushes the linear slider to move in the linear groove, and then drives the two slide bars to move away from each other along the slide groove through the connecting rod. On the contrary, when retracted, the slide bars move closer to each other.

[0030] The slope surface 71 in the utility model is arranged on the wall surface close to the clamping member 1 5 and the clamping member 2 6 on the same side. When the slide bar contacts the clamping member 1, the clamping member 2 is in an unextruded state and can be retracted into the caliper. On the contrary, when the slide bar contacts the clamping member 2, the clamping member 1 is retracted. In this way, the switching between the two is realized.

[0031] The electromagnetic locking device 8 in the utility model includes a magnet housing 81 arranged on the left and right walls of the caliper 2, an electromagnet 82 that can contact the clamping part 1 5 and the clamping part 2 6 is arranged inside the magnet housing 81, an embossing 83 is arranged on the electromagnet 82, and a concave pattern 84 that matches the embossing 83 is arranged on the clamping part 1 5 and the clamping part 2 6. The clamping part 1 and the clamping part 2 are fixed by energizing the electromagnet. After energizing, the electromagnet realizes electromagnetic fixation of the clamping part 1 and the clamping part 2, and the embossing and the concave pattern are cross-engaged to achieve further tightening, so that the clamping part 1 and the clamping part 2 are stabilized.
