Description

Technical Field

[0001] This utility model relates to the field of chuck auxiliary repair tools, specifically, to a machine tool chuck repair device. Background Technology

[0002] In machining, chucks are frequently used to clamp workpieces when machining on a lathe. Over time, the positioning accuracy of the chucks can deviate, leading to workpiece precision errors. To prevent workpiece eccentricity and runout during machining, milling and turning processes are performed on the chucks to improve their clamping accuracy and correct their self-centering accuracy. Repairing chucks requires a specialized chuck repair device to reposition and clamp them securely.

[0003] For example, utility model patent CN221559860U discloses a machine tool three-jaw chuck jaw repair device, including jaws, a chuck connected to the bottom of the jaws, and three fixing bodies between the jaws and the chuck. Each fixing body includes a jaw sleeve, a strip-hole bracket, a bolt bracket, an anti-deviation support plate, a bolt, and a nut. The strip-hole bracket is located on one side of the jaw sleeve, and the bolt bracket is located on the other side. An anti-deviation support plate is located outside the bolt bracket, and a bolt and a nut are mounted on the bolt. This machine tool three-jaw chuck jaw repair device can quickly correct the self-centering accuracy of the jaws, and is simple, easy to use, and highly efficient. However, this device cannot simultaneously repair the jaws at the machine head and tail. Utility Model Content

[0004] In order to simultaneously repair the head and tail chucks and improve the clamping stability during chuck repair, the technical solution adopted by this utility model is: a machine tool chuck repair device, including a connecting rod and a pair of chucks;

[0005] The connecting rod is connected between the pair of chucks and is used to press the chucks against the head chuck assembly plate and the tail chuck assembly plate, respectively.

[0006] The chuck has several straight slots, which are arranged along the radial direction of the chuck. The straight slots are used for clamping by the head jaws or tail jaws.

[0007] Based on the above, in order to ensure the stability of the clamping during repair and prevent it from falling off, the straight clamping slots on different clamping discs are misaligned.

[0008] Based on the above, the specifications of the pair of chucks are the same.

[0009] Based on the above, the specifications of the pair of chucks are different.

[0010] Based on the above, the chuck is provided with three straight slots, and the three straight slots are arranged in a circular array on the chuck.

[0011] Based on the above, in order to facilitate the entry of the head and tail chucks, the straight chuck groove is a U-shaped groove with an open outer end.

[0012] Based on the above, the machine tool chuck repair device also includes an auxiliary disk used in conjunction with the chuck. The auxiliary disk has several arc-shaped slots that gradually converge inward along the radial direction of the auxiliary disk. The auxiliary disk is used to move the head chuck and the tail chuck inward.

[0013] Based on the above, an assembly hole is provided at the center of the auxiliary disk.

[0014] This utility model has substantial features and advancements compared to existing technologies. Specifically, the machine tool chuck repair device provided by this utility model installs chucks with straight grooves at both ends of a connecting rod and designs auxiliary disks with arc-shaped grooves. This allows for the simultaneous locking and positioning of the head and tail chucks when positioning the inner or outer chuck series and then repairing the cutting tool and other tools. This facilitates the simultaneous repair of the head and tail chucks and can realistically simulate the actual working conditions when the head and tail chucks clamp the workpiece, enabling simulated repair.

[0015] Furthermore, during installation, by staggering the installation of multiple straight slots, the phenomenon of the machine tool chuck repair device detaching from the chuck is avoided, thereby improving the clamping stability during chuck repair. Attached Figure Description

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0020] Example 1

[0021] This embodiment provides a machine tool chuck repair device, such as... Figure 1As shown, it includes a connecting rod 3 and a pair of chucks. The connecting rod 3 is connected between the pair of chucks and is used to press the chucks against the head jaw assembly plate and the tail jaw assembly plate, respectively.

[0022] The chuck has several straight slots, which are arranged along the radial direction of the chuck. The straight slots are used for clamping by the head jaws or tail jaws.

[0023] In this embodiment, the chuck has three straight slots arranged in a circular array. To facilitate the entry of the head and tail jaws, the straight slots are U-shaped grooves with open outer ends. Specifically, the pair of chucks can be designated as the first chuck 1 and the second chuck 4. Based on the distribution of the straight slots, the straight slot on the first chuck 1 is designated as the first straight slot 2, and the straight slot on the second chuck 4 is designated as the second straight slot 5.
