Description

Technical Field

[0001] The utility model relates to the technical field of horizontal lathe equipment, in particular to a high-precision guide rail device of a horizontal lathe. Background Art

[0002] A guide rail is a device with grooves or ridges made of metal or other materials that can bear, fix, guide and reduce friction of moving devices or equipment. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called slide rails, linear guides, and linear slides. They are used in linear reciprocating motion occasions and have higher rated loads than linear bearings. At the same time, they can bear a certain torque and can achieve high-precision linear motion under high load conditions.

[0003] The Chinese utility model with patent number CN210790006U discloses a high-precision guide rail device for a horizontal lathe. By setting a rotating motor and a coupling and other devices, the rotating motor is a servo motor. By setting the various values ​​of the servo motor, the overall accuracy of the lathe guide rail can be improved. The rotating motor drives the lead screw to rotate through the coupling, so that the tool holder makes a specified linear displacement. Compared with the guide rails of other horizontal lathes, the guide rails of this lathe have higher and better precision. The device has a simple structure and is convenient and practical. By setting structures such as an air pump, an air pipeline and an exhaust hole, air is pumped into the interior of the guide rail body through the air pipeline through the air pump and then discharged from the exhaust hole, thereby flushing away impurities in the gap between the guide rail body and the tool holder, without affecting the normal operation of the lathe. However, the above-mentioned gas only blows the impurities in the gap between the guide rail body and the tool holder upward, and the impurities in the slide groove of the guide rail body still exist. The part of the tool holder that is located in the slide groove of the guide rail body and is slidably connected is still affected by the impurities in the slide groove. Utility Model Content

The motor is fixedly installed on one end of the workbench through a machine base, and the other end of the workbench is fixed to the support plate with screws. The rotating shaft end of the motor is connected to the screw rod through a coupling, and the other end of the screw rod is connected to the support plate through a bearing. The screw rod is threadedly connected to the tool holder, and the bottom of the tool holder is slidably connected to a T-shaped slide groove arranged on the guide rail, and a plurality of debris leakage holes are arranged at intervals on the bottom of the T-shaped slide groove. A mounting frame is installed on the bottom surface of the workbench at the position of the debris discharge groove on the workbench, and a debris collection box is connected inside the mounting frame.

[0005] The purge mechanism is composed of an air pump and an air pipe. The air outlet of the air pump is connected to the air pipe. The air pipe extends into the guide rail and is installed in the guide rail in a U-shaped structure. A plurality of air holes are arranged at certain intervals on the air pipe.

[0006] A plurality of air outlet holes are arranged at certain intervals on the groove walls on both sides of the T-shaped groove, and each of the air outlet holes corresponds to the position of the air delivery hole on the air delivery pipe.

[0007] A sundry collection box is installed in the mounting frame in a drawer connection manner, and a handle is arranged on the sundry collection box.

[0008] Furthermore, the T-shaped protrusion arranged at the lower end of the tool holder is slidably connected in the T-shaped slot of the guide rail, and the bottom surface width of the lower end of the tool holder is the same as the top surface of the guide rail, thereby avoiding a gap between the tool holder and the guide rail.

[0009] Beneficial effects of the utility model:

[0010] The utility model provides a plurality of debris leakage holes on the bottom of the T-shaped chute of the guide rail, and the debris and impurities flying into the chute during the machine tool processing fall into the debris collection box from the debris leakage holes. The air delivery holes on the air delivery pipe in the purge mechanism correspond to the air outlet holes provided on the groove walls on both sides of the T-shaped chute of the guide rail. The gas output in each air outlet blows away the impurities on the T-shaped chute of the guide rail, and falls into the debris collection box from the debris leakage holes, thereby reducing the problem that the impurities in the chute of the guide rail affect the movement of the tool holder.
