Drawbar type inclined cutting machine having better heat dissipation effect

Abstract

The invention discloses a drawbar type inclined cutting machine having a better heat dissipation effect. The drawbar type inclined cutting machine is characterized in that the drawbar type inclined cutting machine comprises a base, a working table, a support, a rocker arm, a sliding bar component, a machine body, a driving device, a control device and a saw blade; a rotating table of the working table is rotationally arranged on the base; the rotating table is provided with a notch groove along the front-back direction; the support is fixedly arranged at the rear part of the upper side of a supporting part of the base; the rocker arm component comprises a rocker arm; the rocker arm is rotationally arranged at the rear end of the rotating table, and can rotate towards the left side and the right side; the machine body is arranged on the rocker arm through the sliding bar component; the driving device is a brushless direct current motor; a stator is fixedly arranged on the machine body; the axis of the stator is arranged horizontally along the left-right direction; a brushless motor outer rotor assembly allows a driving shaft of the brushless motor outer rotor assembly to penetrate through the stator from the right to left, and then is rotationally arranged on the machine body through a corresponding bearing assembly; a corresponding part of the stator is positioned in a motor casing; the saw blade is detachably and fixedly arranged on the driving shaft of the brushless motor outer rotor assembly of the driving device; and the driving device is electrically connected with the control device.

Description

[0001] This invention is a divisional application of the invention patent application with the application number 201410385347.2, the application date is August 06, 2014, and the invention name is "tie rod type oblique cutting machine". technical field [0002] The invention relates to the field of cutting machines, in particular to a rod-type oblique cutting machine with a saw blade that can move along its radial direction. Background technique [0003] As a cutting tool that can cut both metal materials and non-metal materials, the bevel cutting machine is widely used in various industries. The oblique cutting machine is easy to operate and has high cutting efficiency. During the cutting operation, hold the operating handle and press down to perform the cutting operation; when the workpiece to be cut is wide, the operating handle can be pulled to make the saw blade move radially, thereby cutting the workpiece; when cutting at a certain angle, you can use the Adjust the ro...

Problems solved by technology

", it can be seen that the installation of the cage is more complicated, and the efficiency of production and installation is low

First of all, setting multiple cages in the same first groove is cumbersome to install and requires high machining accuracy of the cages. It is not only necessary to ensure that the connection between the cages is accurate but also to ensure that the cages can be just inserted into the first cage after they are connected. In the groove; secondly, it is necessary to ensure that the cages that are not in the same first groove correspond to each other in the axial direction of the casing, otherwise the permanent magnet will not be installed, and the installation efficiency will be greatly reduced; finally, each cage is embedded in the In the case, the first groove is opened on the inner rotating surface of the case, which is troublesome to process. At the same time, the thickness of the case needs to be increased accordingly, resulting in a corresponding increase in production costs.
