Description

Improved structure of the tailstock of ordinary lathe

technical field

The utility model relates to a lathe, in particular to an improved structure of a common rear seat bed, which belongs to the improvement of lathe accessories.

Background technique

As we all know, the tailstock of ordinary lathes has no automatic feeding function at present, and the drilling or reaming is realized by turning the handwheel to realize the feeding of the drill bit or reamer; not only the labor intensity is high, the efficiency is low, and the feeding amount is uneven, The drill or reamer is easily damaged, and the finish of the hole wall is not ideal.

Contents of the invention

Aiming at the above-mentioned defects in the prior art, the utility model aims to provide an improved structure of the tail stock of a common lathe that can realize automatic feeding.

In order to achieve the above purpose, the utility model adopts the following technical solutions: it includes a tailstock assembly fixed on the guide rail; the lead screw of the tailstock assembly is connected with the electric deceleration device fixed on the guide rail through a coupling, The device is composed of a sliding seat fixed on the guide rail through splints and bolts, a reducer fixed on the sliding seat, and a motor connected to the input shaft of the reducer. The shaft sleeve, the large flat key connecting the shaft sleeve and the output shaft, the small flat key connecting the shaft sleeve and the leading screw, and the pressing plate fixed on the leading screw by a lock nut constitute.

The reducer is a cycloid reducer; the sliding seat is fixed with a frequency conversion speed regulator electrically connected with the motor.

Compared with the prior art, the utility model replaces the traditional handwheel with an electric deceleration device on the basis of the original structure due to the above-mentioned technical scheme, so that the automatic feeding of the tailstock sleeve of the lathe can be realized, which not only reduces labor intensity, but also improves It not only completely eliminates the defect that manual feeding is easy to cause damage to the tool, but also improves the processing quality. The utility model does not need to make any changes to the structure of the traditional lathe, and does not affect the use of the traditional function of the tailstock; it has the advantages of simple structure, convenient use, labor saving and high efficiency.
