Description

Movable type online horizontal lathe center repairing device

Technical Field

The utility model belongs to the top field of lathe, concretely relates to portable online top device of horizontal lathe of restoreing.

Background

In the prior art, a centre is a necessary tool for processing shaft parts by a horizontal lathe, the centre is required to be used for positioning when a workpiece is processed, and the precision of the processed part is directly influenced by conical surface damage and run-out tolerance of the centre. The conical surface of the sleeping car center needs to bear the weight and the processing load of a workpiece, impact can be caused between the conical surfaces of the upper and lower workpiece centers and the workpiece repeatedly, the rotating speed of the center is high during processing of the workpiece, and the like. This has the disadvantage that:

1. when the precision of the used center does not meet the requirement, the quality of the produced product cannot be guaranteed.

2. The dismounting and replacing of the sleeper centre is high in cost, the repairing time is long, the requirement on the skill level of workers is high due to the fact that the lathe centre needs to be repeatedly ground with the conical surface when the lathe centre is assembled, and meanwhile the production efficiency is affected.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a portable restores the top device of horizontal lathe on line can restore the horizontal lathe top on line.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a top device of horizontal lathe is restoreed on line to movable type, includes the lathe tailstock, it is top to install the lathe tailstock, lathe tailstock fixedly connected with base, pedestal mounting has motor and reduction gear, motor drive reduction gear, the reduction gear cover has the belt, top passes through the belt with the reduction gear and is connected, the adjustable knife rest that is used for installing lathe tool or polishing abrasive paper that is provided with in side of top conic section.

Further, the tool rest comprises a supporting plate, and the supporting plate is rotatably connected with the tailstock of the machine tool.

Further, the base is also provided with a tension wheel, and the tension wheel is matched with the belt.

Further, the base is connected with a tailstock of the machine tool through a pressing plate and is fixed through bolts.

Further, a frequency converter is arranged in the motor to adjust the rotating speed of the motor.

Furthermore, the upper wheel disc of the speed reducer is parallel to the cylindrical surface of the tip and is on the same central line.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a motor drive belt drives top rotation, installs the lathe tool in order to restore top on the knife rest, changes the lathe tool for polishing abrasive paper in order to the polishing of apex to the realization is to top online restoration.

FIG. 3 is a schematic view of polishing;

in the drawings, the components represented by the respective reference numerals are listed below:

1. the machine tool comprises a machine tool tailstock, 2 parts of a tip, 3 parts of a base, 4 parts of a motor, 5 parts of a speed reducer, 6 parts of a belt, 7 parts of a turning tool, 8 parts of a tool rest, 9 parts of a pressure plate, 10 parts of a tension wheel, 11 parts of polishing abrasive paper.

Detailed Description

The present invention is further described in detail below with reference to specific embodiments so that those skilled in the art can more clearly understand the present invention.

As shown in fig. 1-3, a portable device of restoreing horizontal lathe top on line, includes machine tool tailstock 1, top 2 is installed to machine tool tailstock 1, machine tool tailstock 1 fixedly connected with base 3, motor 4 and reduction gear 5 are installed to base 3, motor 4

drive reduction gear

5, 5 covers of reduction gear have belt 6, top 2 is connected through belt 6 with reduction gear 5, the adjustable knife rest 8 that is provided with in one side of top 2, knife rest 8 is used for installing lathe tool 7 or polishing abrasive paper 11 respectively in order to be used for top 2 restoration or polishing.

As shown in fig. 1-2, the turning tool 7 is mounted on the tool rest 8, the tool rest 8 is adjusted to enable the turning tool 7 to be located at the side face of the conical section of the tip 2, the motor 4 is started, the belt 6 drives the tip 2 to rotate, and at the moment, the turning tool 7 repairs the conical surface damage or the runout tolerance of the tip 2.

After the restoration is completed, as shown in fig. 1 and 3, the polishing sand paper 11 is installed on the tool rest 8, the tool rest 8 is adjusted to enable the polishing sand paper 11 to be located at the side face of the conical section of the tip 2, the motor 4 is started, the belt 6 drives the tip 2 to rotate, and the polishing sand paper polishes the conical surface of the tip 2, so that the surface roughness of the conical surface meets the use requirement.
