Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a numerically controlled lathe with a waste chip cleaning mechanism. Background Art

[0002] A CNC lathe is a high-precision, high-efficiency automated machine tool equipped with a multi-station turret or a power turret. It can process complex workpieces such as straight cylinders, oblique cylinders, arcs, and various threads, grooves, worms, etc. With the development of manufacturing technology, CNC lathes have become popular and practical due to their high processing efficiency.

[0003] CNC lathes are mostly used for batch processing. The processing time of workpieces is relatively short. The surfaces of the worktable tracks and feed screws are oiled for lubrication and protection. During the processing, waste chips will be scattered on the worktable tracks and feed screws, causing movement jams or getting stuck inside the structure, affecting the processing accuracy. The staff is required to clean out the waste chips. Frequent cleaning is very inconvenient, affecting processing efficiency and increasing the labor intensity of the staff. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides a CNC lathe with a waste chip cleaning mechanism, including a machine tool base 1, a spindle box 2 is fixed to one side of the machine tool base 1, a spindle 3 is arranged in the spindle box 2, a feed threaded rod 4 is arranged in the machine tool base 1, a workbench 5 is arranged on the feed threaded rod 4, waste chip cleaning mechanisms 6 are arranged on both sides of the workbench 5, and a tool holder 7 is arranged on the workbench 5.

[0022] refer to Figure 1-4 The waste chip cleaning mechanism 6 includes a dust cover 601, a screw through hole A602, and a cleaning brush 603; the dust cover 601 is fixed to the side of the workbench 5, a screw through hole A602 is opened in the center of the dust cover 601, and a cleaning brush 603 is fixed inside the dust cover 601, and the cleaning brush 603 is fixed along the thread direction of the surface of the feed threaded rod 4.

[0023] By installing the waste chip cleaning mechanism 6, the dust cover 601 on the surface of the waste chip cleaning mechanism 6 covers the part of the feed thread rod 4 close to the workbench 5 to prevent waste chips from falling on it, so that the workbench 5 can move smoothly in the direction of the feed thread rod 4 when processing a workpiece with a short axial direction; at the same time, a cleaning brush 603 is installed in the waste chip cleaning mechanism 6, and the brush head of the cleaning brush 603 is distributed along the thread direction of the surface of the feed thread rod 4. When processing a longer workpiece, the rotation of the feed thread rod 4 drives the workbench 5 to move in the direction of the feed thread rod 4, and the cleaning brush 603 moves in the thread of the feed thread rod 4 to remove the waste chips in the thread, keep the feed thread rod 4 clean, and enable the workbench 5 to work smoothly, thereby improving the workpiece processing efficiency.

[0024] refer to Figure 4 , Figure 5 A screw hole B501 is provided below the workbench 5, a track 502 is provided on the upper surface of the workbench 5, a tool holder mounting seat 503 is slidably provided on the track 502, a tool holder 7 is fixed on the tool holder mounting seat 503, a chip pusher plate 504 is fixed at the front end of the tool holder mounting seat 503, a chip pusher slope 505 is provided on the top of the chip pusher plate 504, and the lower end of the chip pusher slope 505 is covered with a rubber push plate 506 that fits on the track 502.

[0025] By installing a chip pusher plate 504 at the front end of the tool holder mounting seat 503 and setting a chip pusher slope 505 on the top of the chip pusher plate 504, the chip pusher slope 505 can isolate the waste chips that directly fall on the tool holder mounting seat 503 from the track 502, reducing the amount of waste chips that enter and get stuck on the tool holder mounting seat 503. A rubber pusher plate 506 is installed at the top of the chip pusher slope 505 where it fits the track 502 to push out the waste chips that fall on the track 502, thereby keeping the track 502 clean and tidy, allowing the tool holder mounting seat 503 to run stably and maintaining the workpiece processing efficiency.

[0026] How to use

[0027] The working principle and use process of the utility model are as follows: when the CNC lathe is processing a workpiece, the tool holder 7 will move in the feed direction and the axis diameter direction. As the processing time becomes longer, the processing waste chips will accumulate on the feed thread rod 4 and the track 502, affecting the smooth operation of the worktable 5. In the feed direction, the dust cover 601 on the surface of the waste chip cleaning mechanism 6 covers the part of the feed thread rod 4 close to the worktable 5 to prevent waste chips from falling on it, thereby ensuring that the running distance of the worktable 5 is not affected by waste chips when processing small workpieces. At the same time, the cleaning brush 603 installed in the waste chip cleaning mechanism 6 has a brush head distributed along the thread direction of the surface of the feed thread rod 4. When processing longer workpieces, the rotation of the feed thread rod 4 drives the worktable 5 to move in the direction of the feed thread rod 4, cleaning The head of the cleaning brush 603 extends into the thread of the feed threaded rod 4 and moves, and as the workbench 5 moves forward, the waste chips in the thread are removed, keeping the feed threaded rod 4 clean and tidy, so that the workbench 5 can work smoothly; in the axial direction, a chip pusher plate 504 is installed at the front end of the tool holder mounting seat 503, and a chip pusher slope 505 is set on the top of the chip pusher plate 504. The chip pusher slope 505 isolates the waste chips that fall directly on the tool holder mounting seat 503 from the track 502, reducing the situation where waste chips enter and jam the tool holder mounting seat 503, and a rubber pusher plate 506 is installed at the top of the chip pusher slope 505 where it fits the track 502. As the rubber pusher plate 506 moves back and forth, the waste chips that fall on the track 502 are pushed out, keeping the running part of the tool holder mounting seat 503 on the track 502 clean, so that the tool holder mounting seat 503 can run stably.
