Description

TECHNICAL FIELD

[0001] The application relates to the technical field of electric tool holders, in particular to a numerical control lathe electric tool holder. BACKGROUND

[0002] The electric tool holder is an important functional component of the numerical control lathe, and its performance directly affects the cutting performance and operation reliability of the lathe. The current electric tool holder with worm gear transmission and tooth disc meshing structure has the advantages of fast indexing, stable performance, high positioning accuracy and the like.

[0003] For example, the patent with the publication number CN209969583U specifically discloses a multifunctional four-station electric tool holder. The upper tool body of the tool holder is a cuboid structure, has an inner recessed platform along the outer four walls, is used for placing a machine clamp tool, and a screw fastens the machine clamp tool in the inner recessed platform through the upper surface of the upper tool body. The middle part of the upper tool body is provided with a through hole with an inner thread, which is matched with the outer thread on the screw rod. The lower surface of the upper tool body is provided with an end face tooth, which is meshed with the end face tooth on the upper surface of the lower tool body, so as to install the tool in the tool holder.

[0004] In the above patent, the electric tool holder fastens the tool in the tool holder through the setting of multiple screw rods and two tool bodies. However, since the open installation groove is arranged between the upper tool body and the lower tool body, when the tool is installed in the installation groove and starts machining, the installation groove is always exposed outside, so that the cutting debris generated during cutting machining enters the installation groove. If the debris accumulates too much and suddenly falls off, it may splash on the workers or other parts of the machine tool, causing personal injury or equipment damage. Therefore, it is necessary to provide a numerical control lathe electric tool holder which can shield the installation groove to solve the above problems.

[0005] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background technology of the concept of the present application, and therefore, it can contain information which does not constitute prior art. SUMMARY

DETAILED DESCRIPTION

[0020] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0022] As Figures 1-2 shown, the present application provides a numerical control lathe electric tool rest, comprising a base 1, which is arranged in a machining workshop. One side of the base 1 is provided with a clamping assembly 2, which comprises a drive box 21. Two groups of rotary motors are arranged in the drive box 21. The output end of one group of rotary motors penetrates the drive box 21 and is fixedly installed with a clamping jaw 22. The clamping jaw 22 is used to clamp a workpiece to be machined, and the clamping jaw 22 is adapted to rotate the workpiece under the driving of the rotary motor.

[0023] Meanwhile, a slide rail 11 is arranged on the top of the base 1. The top of the slide rail 11 is provided with a cutting assembly 3, which comprises a mounting table 31. The mounting table 31 is slidingly installed on the slide rail 11. A screw rod is fixedly installed on the output end of the other group of rotary motors in the drive box 21. The other end of the screw rod is rotatably installed on the base 1 through a bearing seat. A screw thread is arranged on one side of the bottom of the mounting table 31, which is engaged with the screw rod. Thus, the mounting table 31 is adapted to move on the slide rail 11 under the driving of the rotary motor.

[0024] Meanwhile, the electric tool rest 32 is rotatably installed on the top of the installation table 31, and is adapted to rotate on the top of the installation table 31 under the driving of an external PLC control system, thereby completing multi-directional cutting work. Meanwhile, a signaling disc is arranged in the electric tool rest 32, and is made of a disc body, a circuit board, a work station Hall element, a reply signal Hall element, a current limiting resistor, a triode, a signal output terminal, and a corresponding work station magnetic steel. The triode output level is switched by using the Hall element, so that high level output is achieved, and the electric tool rest 32 can be used in high-end numerical control systems such as FANUC.

[0025] As shown in Figures 2-3 the electric tool rest 32 includes a lower tool seat 33 arranged on the top of the installation table 31, an upper tool seat 34 arranged on the top of the lower tool seat 33, and an installation groove 35 arranged between the lower tool seat 33 and the upper tool seat 34 and used for installing a turning tool. A plurality of bolts 36 are installed on the upper tool seat 34 and used for fixing the turning tool in the installation groove 35.

[0026] Meanwhile, a shielding assembly 4 is arranged outside the installation groove 35, and includes a baffle 5 rotatably installed on the upper tool seat 34. The baffle 5 is larger in size than the installation groove 35, and is used for preventing debris from entering the installation groove 35 during machining. A handle is arranged on the bottom of the baffle 5 and is used for facilitating workers to grab the baffle 5. A magnetic plate 51 is installed outside the baffle 5, and a metal plate 52 is arranged outside the upper tool seat 34 and corresponds to the magnetic plate 51. The metal plate 52 is adapted to the magnetic plate 51, so that the baffle 5 can be temporarily fixed on the upper tool seat 34 through cooperation of the metal plate 52 and the magnetic plate 51 when the turning tool is installed.

[0027] Two groups of jack plugs 53 are arranged outside the lower tool seat 33, and two groups of jack blocks 54 are arranged inside the baffle 5 and correspond to the jack plugs 53. The jack blocks 54 are adapted to the jack plugs 53 in size, so that the baffle 5 can be fixed on the lower tool seat 33 through cooperation of the jack blocks 54 and the jack plugs 53 after the turning tool is installed. At this time, the baffle 5 can completely shield the installation groove 35.

[0028] When the turning tool needs to be installed on the electric tool rest 32, the baffle 5 is first opened by the handle and is installed on the upper tool seat 34 of the turning tool. Then, the turning tool is placed into the installation groove 35, and is tightly installed in the installation groove 35 by rotating the bolts 36. Finally, the baffle 5 is driven by the handle to shield the installation groove 35, thereby completing the installation of the turning tool.

[0029] In summary, the device is provided by setting the shielding component 4, so that the turning tool can be blocked by the baffle 5 after installation, preventing the debris generated during processing from entering the installation groove 35, reducing the subsequent cleaning operation, and increasing the practicality of the device.

[0030] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Those skilled in the art can make various changes and modifications to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
