Description

A extend cutter head for lathe

Technical Field

The utility model relates to a lathe field especially relates to an extend cutter head for lathe.

Background

The machine tool is the basis of modern industry, the machine tools all have certain stroke distance and are used for processing workpieces in the stroke of the machine tool, and if the size of the workpiece exceeds the stroke of the machine tool, the processing cannot be carried out, so that the application range of the machine tool is limited; in order to process a workpiece with a larger size, a machine tool with a larger size needs to be selected or clamping needs to be carried out for multiple times, and the processing cost of the workpiece or the purchasing cost of the machine tool can be increased, so that the guarantee of product precision is not facilitated; therefore, a milling head capable of increasing the stroke of the machine tool is needed to solve the problem of insufficient stroke of the machine tool.

Therefore, a milling head capable of increasing the stroke of the machine tool is needed to solve the problem of insufficient stroke of the machine tool.

SUMMERY OF THE UTILITY MODEL

First, technical problem to be solved

The utility model aims at the above-mentioned problem that prior art exists, provide a extend cutter head for lathe especially, solve the not enough problem of current lathe stroke.

Second, technical scheme

In order to solve the technical problem, the utility model provides an extend cutter head for lathe, an extend cutter head for lathe includes: a shell, a driving wheel and a driven wheel; the shell is connected with a milling head of a machine tool, the driven wheel is arranged on the shell, the driving wheel is arranged on a main shaft of the machine tool through the numerical control tool holder, and the driving wheel and the driven wheel are in transmission connection.

Wherein, the driving wheel and the driven wheel are in transmission connection through a synchronous belt.

Wherein, the transmission ratio between the driving wheel and the driven wheel is 1 to 1.

Wherein, a tensioning device is also arranged in the shell.

Wherein the tensioning device is a tensioning wheel.

The milling head further comprises a loose clamp cutter detection device and a loose clamp cutter mechanism.

Wherein, the cutter head still includes boring bar interlock detection device.

Thirdly, the beneficial effects of the utility model

Compared with the prior art, the utility model discloses an extend cutter head for lathe has following beneficial effect:

(1) through the design of the driving wheel and the driven wheel, the axes of the original main shafts are parallel and extend in a radial offset manner, the stroke of the original machine tool is increased, the machine tool can machine larger parts, and the machining range of the machine tool is improved.

(2) Through the design of hold-in range, can possess good overload protection, avoid lathe and cutter head to damage because of transshipping.

(3) Through synchronous belt drive 1: 1, the synchronous effect of the original machine tool spindle and the spindle of the auxiliary milling head can be realized, and the functions of milling, drilling, tapping and the like can be realized.

(4) The original structure of the machine tool is not damaged when the milling head is installed, the boring rod of the machine tool can freely stretch out and draw back after the synchronous belt is detached, the original function of the machine tool can be recovered by replacing the cutter handle provided with the driving wheel, the whole milling head does not need to be detached, and the switching between the expansion function and the original function of the machine tool is facilitated.

In the figure: 1 is a shell; 2 is a driving wheel; 3 is a driven wheel; 4 is a knife handle; 7, a loose clamping knife detection device; and 8, a unclamping knife mechanism.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

The first embodiment is as follows:

the structure of the extended cutter head for a machine tool of the present embodiment includes, as shown in fig. 1 to 2:

casing 1, driving wheel 2, driven wheel 3

The shell 1 is connected with a milling head of a machine tool, the driven wheel 3 is arranged on the shell 1,

the driving wheel 2 is fixed on the numerical control tool shank and is arranged on the boring bar in a mode of installing a tool, the driving wheel 2 can rotate synchronously when the boring bar rotates, and 1-to-1 transmission is realized between the driving wheel 2 and the driven wheel 3 through a synchronous belt, so that the driven wheel 3 has the same rotating speed as the driving wheel 2, the driven wheel 3 is also used for installing the numerical control tool shank, and the driven wheel 3 can drive the tool to realize the functions of milling, drilling, tapping and the like by rotating;

when the milling head does not need to be expanded to process, the synchronous belt is only needed to be dismounted, the numerical control knife handle provided with the driving wheel 2 can be replaced by the numerical control knife handle provided with other tools, the original processing mode of the machine tool is realized, the shell and the driven wheel do not need to be dismounted, and the switching time between the expanded function and the original function is shortened.
