Abstract
The utility model discloses a kind of polished rod protective device, comprise lathe, motor, polished rod, also comprise pedestal, protective sleeve, spring, steel ball, lock screw, described pedestal is positioned at gearbox right side wall lower end, it is connected with electric machine main shaft screw thread, described protective sleeve is positioned on the left of polished rod, the two is rotatedly connected, its shape is cylindrical, protective sleeve top is also provided with some installing holes, hole is through hole, described spring is positioned at installing hole, described steel ball is positioned at spring upper end, described lock screw is positioned at protective sleeve sidewall, the two screw thread is connected, this protector, synchronous groove is departed from by the speed official post steel ball of polished rod and main shaft, thus reach polished rod and be separated with motor, realize the object of protection polished rod.
Description
Technical field
The utility model relates to a kind of protector, particularly relates to a kind of polished rod protective device.
Background technology
Lathe has consequence in field of machining, the all indispensable equipment of mechanical field and even whole industrial circle, the core transmission component of the lathe especially of the polished rod on lathe, but because part hardness is high or the depth of cut is crossed conference and caused polished rod locking in turning process, but now motor is still running up, very easily causing polished rod to be out of shape and even scrapping.In view of above-mentioned defect, be necessary to design a kind of polished rod protective device in fact.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of polished rod protective device, and the problem of locking damage polished rod occurs when solving turning.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of polished rod protective device, comprise lathe, motor, polished rod, also comprise pedestal, protective sleeve, spring, steel ball, lock screw, described pedestal is positioned at gearbox right side wall lower end, it is connected with electric machine main shaft screw thread, described protective sleeve is positioned on the left of polished rod, the two is rotatedly connected, its shape is cylindrical, protective sleeve top is also provided with some installing holes, hole is through hole, described spring is positioned at installing hole, described steel ball is positioned at spring upper end, described lock screw is positioned at protective sleeve sidewall, the two screw thread is connected.
Further, described pedestal top is also provided with boss, and its shape is circular.
Further, described boss top is also provided with synchronous groove, and it is some " V " type groove.
Further, be also provided with screwed hole in the middle part of described protective sleeve sidewall, it is through hole.
Further, described protective sleeve top mounting holes end is also provided with screw.
Compared with prior art, this protector, when lathe normally works, steel ball in protective sleeve installing hole withstands in " V " type groove at pedestal top under the elastic force of spring, protective sleeve is fixed on polished rod by side pressure by the lock screw of protective sleeve sidewall, realize polished rod, pedestal, protective sleeve run-in synchronism, when there is the urgent locking of lathe, the pedestal of driven by motor still does High Rotation Speed, but due to locking, the speed of polished rod can be slowed down and even be stopped, now because the speed difference of polished rod and main shaft causes steel ball to depart from synchronous groove, thus reach polished rod and be separated with motor, realize the object of protection polished rod.

Following detailed description of the invention will further illustrate in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Hereinafter, set forth multiple specific detail, to provide the thorough understanding to the concept forming described embodiment basis.But to one skilled in the art, embodiment described obviously can be put into practice when not have in these specific detail some or all.In other cases, well-known treatment step is not specifically described.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, comprise lathe 1, motor 2, polished rod 3, gearbox 4, pedestal 5, protective sleeve 6, spring 7, steel ball 8, lock screw 9, synchronous groove 501, screw 601, pedestal 5 is positioned at gearbox 4 right side wall lower end, it is connected with motor 2 spindle thread, protective sleeve 6 is positioned on the left of polished rod 3, the two is rotatedly connected, its shape is cylindrical, protective sleeve 6 top is also provided with some installing holes, hole is through hole, spring 7 is positioned at installing hole, steel ball 8 is positioned at spring 7 upper end, lock screw 9 is positioned at protective sleeve 6 sidewall, the two screw thread is connected, pedestal 5 top is also provided with boss, its shape is circular, boss top is also provided with synchronous groove 501, it is some " V " type groove, also screwed hole is provided with in the middle part of protective sleeve 6 sidewall, it is through hole, protective sleeve 6 top mounting holes end is also provided with screw, this protector, when lathe 1 normally works, steel ball 8 in protective sleeve 6 installing hole withstands in " V " type groove at pedestal 5 top under the elastic force of spring 7, protective sleeve 6 is fixed on polished rod 3 by side pressure by the lock screw 9 of protective sleeve 6 sidewall, realize polished rod 3, pedestal 5, protective sleeve 6 run-in synchronism, when there is the urgent locking of lathe 1, the pedestal 5 that motor 2 drives still does High Rotation Speed, but due to locking, the speed of polished rod 3 can be slowed down and even be stopped, now because the speed difference of polished rod 3 and motor 2 main shaft causes steel ball 8 to depart from synchronous groove 501, thus reach polished rod 3 and be separated with motor 2, realize the object of protection polished rod 3.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion made, all drop within protection domain of the present utility model.
