Description

Technical Field

[0001] The utility model relates to the technical field of ball screws, in particular to an anti-lock ball screw. Background Art

[0002] Ball screws play a crucial role in lathe machining. The feed mechanism of the lathe is responsible for controlling the moving distance and speed of the tool on the workpiece. The high-precision transmission of the ball screw enables the feed mechanism to achieve precise feed control, ensuring that the tool cuts according to a predetermined trajectory. This helps to improve machining accuracy and reduce errors. Especially in precision machining, the high-precision characteristics of the ball screw are particularly important.

[0003] However, during the feeding process of the lathe, when the turning tool processes the part, metal chips will be generated. The temperature of the turned metal chips is relatively high, and they will adhere to the thread grooves of the ball screw. When too much metal chips accumulate, the feeding process of the lathe is hindered, the ball screw cannot continue to work, resulting in the locking of the ball screw, affecting the machining accuracy of the part, and greatly likely to damage the lathe components.

[0004] In view of this, this application is specifically proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-lock ball screw to solve the problems raised in the above background art.

Components with the same structure are symmetrically arranged on both sides of the fixing ring. Through sliding channels are provided at the centers of both side walls of the fixing ring. A cleaning rod is slidably connected within the through sliding channels. The cleaning rod is arranged towards the center of the interior of the fixing ring. The cleaning rod penetrates through the arc surface of the fixing ring and is slidably connected to the fixing ring. A rack plate is fixedly connected to the end of the cleaning rod away from the connecting rod. A gear is engaged with the bottom of the rack plate. A first rotating shaft is fixedly connected to the side of the gear away from the connecting rod. A second motor is fixedly connected to the end of the first rotating shaft away from the gear.

[0008] Further, sliding channels one are provided on both sides of the fixed ring and penetrate through. The cleaning rod slides horizontally and longitudinally inside the sliding channel one.

[0009] Further, a certain gap is left in the meshing section between the rack plate and the gear. When the gear moves to the end of the rack plate, the cleaning rod abuts against the inner side wall of the sliding channel one.

[0010] Further, the end of the rotating rod away from the rack plate is rotatably connected to the bottom of the disc away from the center.

[0011] Further, the end of the cleaning rod close to the connecting rod is conical.

[0012] Further, an opening is provided at the top of the slider, and the outlet of the blanking device is aligned with the opening at the top of the slider.

[0013] Further, the opening of the C-shaped rod faces the slider.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Start the second motor. The second motor drives the gear to rotate through the first rotating shaft. The gear drives the rack plate to move longitudinally. The rack plate drives the cleaning rod to slide longitudinally in the sliding channel one, so that the cleaning rod is aligned with the thread groove on the lead screw. Start the third motor. The third motor drives the disc to rotate through the second rotating shaft. The disc drives the rotating rod to rotate. The rotating rod drives the rack plate to move horizontally. The rack plate drives the cleaning rod to slide horizontally in the sliding channel one, so that the cleaning rod abuts against the thread groove of the lead screw. Start the first motor. The first motor drives the lead screw to rotate. The lead screw drives the slider to slide. The slider drives the storage box to slide. The cleaning rod cleans the impurities in the thread groove of the lead screw, avoiding the self-locking of the ball screw and reducing the machining accuracy of the lathe.

[0016] 2. Open the control valve. The lubricating oil in the oil storage tank drips into the opening at the top of the slider through the blanking device to lubricate the balls inside the slider, avoiding the self-locking of the ball screw caused by the wear or rust of the balls.
