Description

Technical Field

[0001] The utility model relates to the technical field of lathes, in particular to a transverse tool table for a CNC precision automatic lathe. Background Art

[0002] The CNC precision automatic lathe is a high-performance, high-precision, low-noise tool-feeding automatic lathe. It is an automatic processing machine tool that controls the processing program through a cam. The tool holder can be installed on the lathe through the tool table.

[0003] For example, a transverse tool table for a CNC precision automatic lathe with the authorization announcement number "CN211192042U" can fix the fixing rod and the card plate at the lower end of the upper cover by means of the edge plate, and insert the fixing rod and the card plate into the card slot. The elastic block can be squeezed during the downward movement of the card plate, and the card plate can be clamped inside the card slot by the elastic block when it moves to the bottom of the elastic block, so that the upper cover is installed on the upper end of the fixing plate, and the card plate is squeezed by the elastic block by pushing the upper cover to one side, and then the card plate can be pulled out from the inside of the card slot. The installation and disassembly are relatively convenient, and it is convenient for the maintenance of the parts inside the through slot after damage. The through slot can be sealed by the upper cover, and the parts inside the through slot can be protected. The internal threaded tube can be fixed to the outside of the wire by the limit plate, and the wire is inserted into the external threaded tube. The internal threaded tube can be fixed to the outside of the external threaded tube by rotating, and then the connection between the wire and the base is completed. The fixation is relatively firm, avoiding the wire from being separated from the base by force, and preventing the tool table from having poor contact during work. The effect of use is better than that of the traditional method. However, the transverse tool table used for the CNC precision automatic lathe is not easy to disassemble because the upper cover is clamped by squeezing the elastic block. The operator needs to use a large force to pull out the rubber block, which requires the operator to consume more physical strength, thereby increasing the manual labor. At the same time, the transverse tool table used for the CNC precision automatic lathe is prone to loosening at the wiring location of the wire due to external force, which causes the wire to be easily damaged by friction, thereby reducing the service life of the wire.

The second turning handle 402 is rotatably connected to the fixed block 3 through a bearing.

[0023] See attached Figure 4 and attached Figure 6

[0024] The limiting mechanism 6 includes a first shell 601, which is rotatably connected to the first handlebar 602 through a bearing, a threaded rod 603 is fixedly connected to the end of the first handlebar 602, the threaded rod 603 is rotatably connected to the first shell 601 through a bearing, the threaded rod 603 is threadedly connected to the first clamping claw 604, the first clamping claw 604 is slidably connected to a groove processed on the inner wall of the first shell 601, and a second clamping claw 605 is fixedly connected to the surface of the first shell 601. When the first handlebar 602 is rotated, the rotation of the first handlebar 602 drives the threaded rod 603 to rotate, thereby driving the first clamping claw 604 to slide along the groove processed on the inner wall of the first shell 601.

[0025] See attached Figure 3 and attached Figure 5

[0026] The auxiliary fixing mechanism 4 includes a second housing 401, the surface of the second housing 401 is fixedly connected to the inner wall of the fixing block 3, the second housing 401 is rotatably connected to the second handle 402 through a bearing, a worm 403 is fixedly connected to the end of the second handle 402, the worm 403 is rotatably connected to the protruding portion of the inner wall of the second housing 401 through a bearing, the worm 403 is meshed with a worm wheel 404, the worm wheel 404 is rotatably connected to the inner wall of the second housing 401 through a pin, a half gear 405 is fixedly connected to the surface of the worm wheel 404, and the half gear 405 is fixedly connected to the surface of the worm wheel 404.

The movement of the moving frame 406 drives the cross bar 407 to slide along the through hole processed on the second shell 401.

[0027] Working principle:

[0028] Cover installation process:

[0029] The operator inserts the cover plate 5 along the slide groove processed on the fixed block 3. When the surface of the cover plate 5 fits with the inner wall of the groove processed on the fixed block 3, the operator turns the second handle 402 counterclockwise. The rotation of the second handle 402 drives the worm 403 to rotate, thereby driving the worm gear 404 to rotate. The rotation of the worm gear 404 drives the half gear 405 to rotate, thereby driving the moving frame 406 to move. The movement of the moving frame 406 drives the cross bar 407 to slide to the left along the through hole processed on the second shell 401. At the same time, the moving frame 406 slides along the slide groove processed on the fixed plate 8. When the end of the cross bar 407 is tightly against the inner wall of the slide groove processed on the cover plate 5, the second handle 402 is stopped. When it is necessary to remove the cover plate 5, the operator turns the second handle 402 clockwise to reset the cross bar 407, so that the operator can more easily take out the cover plate 5 without consuming much physical strength, thereby saving manual labor.

[0030] Wire limiting process:

[0031] The operator manually turns the first handle 602 clockwise, and the rotation of the first handle 602 drives the threaded rod 603 to rotate, thereby driving the first clamping claw 604 to slide backward along the slide groove processed on the inner wall of the first shell 601. When the surface of the first clamping claw 604 and the surface of the second clamping claw 605 are tightly fitted with the surface of the wire, the first handle 602 is stopped to ensure that the wire will not loosen, which can increase the service life of the wire. The fixing block 3 can be installed on the CNC precision automatic lathe through the mounting hole 7, and the tool holder can be connected through the base 1, which is more practical.
