DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] In this embodiment, refer to Figure 1-Figure 4 The specific implementation of a universal tool holder for a lathe includes a dovetail tool plate 1 and a tool holder 2 mounted on the dovetail tool plate 1. A limit groove 3 is provided at the lower end of the tool holder 2. A slidable locking block 5 is mounted on the limit groove 3 through a screw rod 4. The tool holder 2 is fixed to the dovetail tool plate 1 by cooperating with the locking block 5. The locking block 5 can accurately adjust the position in the limit groove 3, thereby achieving the fixation and adjustment of the tool holder 2.

[0020] Furthermore, the screw rod 4 is fixed in the limiting groove 3 through the bearing and the locking sleeve, so that it can only rotate in place. The locking block 5 cooperates with the screw rod 4 through the self-locking nut, so that the knife seat 2 can be better fixed on the dovetail knife plate 1 through the characteristics of the self-locking nut.

[0021] Furthermore, in the present invention, the dovetail groove is designed with a 60-degree angle. The angle of the dovetail blade plate 1 can also be set to 45 degrees to meet different user needs. The dovetail blade plate 1 is firmly mounted on the machine tool or workbench by bolts or other fastening devices to ensure stability and reliability.

[0022] Furthermore, the tool holder 2 includes a fixed block 6 fixed to the dovetail blade plate 1 and a tool holder block 7 mounted on the fixed block 6 by screws. By adopting a split structure for the fixed block 6 and the tool holder block 7, different tool holder blocks 7 can be mounted on the fixed block 6, so that the user has more choices to meet different processing requirements.

[0023] Furthermore, the tool holder block 7 is provided with a through hole 8 for installing a tool. The through hole 8 can be designed as a square hole or a round hole, so that the tool holder block 7 can be selected according to the use requirements of different processing. In this embodiment, a round hole is used to install shaft tools such as a rotary cutter. At the same time, a threaded hole is provided on the tool holder to cooperate with the through hole 8. By inserting the tool into the through hole 8, and then screwing the screw into the threaded hole to contact the tool in the through hole 8, the tool is firmly locked in the through hole 8.

[0024] Furthermore, the tool holder block 7 is provided with a sliding block 10 through a fixed groove 9, and the sliding block 10 is provided with a through groove 11 for installing a tool. The fixed groove 9 and the sliding block 10 can be matched with structures such as a dovetail groove or a T-shaped groove. A through hole is provided on the fixed groove 9, so that the fixed groove 9 can fix the position of the sliding block 10 with screws. The through groove 11 can be provided with a round hole or a square hole according to the use requirements. The utility model adopts a square hole design. In order to install a square tool. The sliding block 10 is also provided with a threaded hole that communicates with the through groove 11. The screw can enter the through groove 11 through the threaded hole to fix the tool.

[0025] Further, the number of the fixing grooves 9 can be one or more, and the number of the sliding blocks 10 corresponds to the number of the fixing grooves 9. In the present invention, two fixing grooves 9 and two identical sliding blocks 10 are used to adapt to more processing requirements.

[0026] Furthermore, a waist-shaped hole 12 is provided on the outside of the tool holder block 7 to cooperate with the sliding block 10. The length of the waist-shaped hole 12 can be set according to actual needs to meet the adjustment requirements of sliding blocks 10 of different sizes. Through the design of the waist-shaped hole 12, the sliding block 10 can be easily moved along the length direction of the waist-shaped hole 12, thereby realizing accurate adjustment of the tool position.

[0027] Furthermore, a knob 13 for adjusting the locking block 5 is provided at one end of the screw rod 4. The screw rod 4 is fixedly matched with the knob 13 through an external hexagon and a screw. Thus, the screw rod 4 can be driven by turning the knob 13 to adjust the position of the locking block 5, thereby achieving the effect of loosening or closing.

[0028] The beneficial effects of the utility model are as follows: a slidable locking block 5 is installed through the limiting groove 3 at the lower end of the knife seat 2, and the locking block 5 is slidably matched with the knife seat 2 through the screw rod 4. The dovetail knife holder can adjust the position of the locking block 5 and fix it on the dovetail knife plate 1 by rotating the screw rod 4, so that it is suitable for dovetail knife plates 1 of different sizes. Thereby, the practicality and convenience of the dovetail knife holder are improved.
