Problems solved by technology

[0008] 1) The main shaft rotation and positioning mechanism is driven by multi-stage gears, and due to the gear gap, it is easy to cause inaccurate positioning;
[0009] 2) After long-term use of the travel switch, it is easy to damage and cause malfunction;
[0010] 3) Due to the malfunction caused by the damage of the travel switch or the inertia of the spindle rotation, the pins set on the turntable are sometimes broken, and the adjustment or replacement is very cumbersome.

Embodiment Construction

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Please refer to figure 2 , image 3 , figure 2 It is a structural schematic diagram of the spindle positioning mechanism of the horizontal boring machine provided by the present invention; image 3 for figure 2 Partial enlarged schematic diagram of the middle I site.

[0039] In a specific embodiment, the present invention provides a spindle positioning mechanism for a horizontal boring machine, which is mainly composed of a controller (not shown in the figure), a spindle motor 10, a position sensing component 11, a sensor 12 and other components. The boring bar 14 of the boring machine 13 is driven to rotate by the spindle motor 10 .

[0040] The position sensing component 11 is arranged on the outer peripheral surfa...

Abstract

The invention discloses a spindle positioning mechanism of a horizontal boring machine. The mechanism comprises a controller, a spindle motor for driving a boring rod to rotate, a position induction part and a sensor, wherein the position induction part is arranged on the boring rod; the sensor is used for detecting the position induction part; the signal output end of the sensor is connected with the controller; and when the boring rod stops positively rotating and negatively rotates to a stop allowable position, the sensor detects the position induction part and outputs a signal to the controller, and the controller controls the spindle motor to stop. By the mechanism, the positioning accuracy and reliability of a spindle of the horizontal boring machine can be obviously improved. The invention also discloses the horizontal boring machine with the spindle positioning mechanism.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a spindle positioning mechanism of a horizontal boring machine. The present invention also relates to the horizontal boring machine of the spindle positioning mechanism. Background technique [0002] Boring machine is the main equipment for processing large box parts. It can be roughly divided into horizontal boring machine, floor boring milling machine and coordinate boring machine. Among them, horizontal boring machine is the most widely used, most widely used and relatively economical boring machine. It is mainly used Hole processing for box or bracket parts and other processing surfaces related to holes. [0003] When the boring machine passes through the workpiece before processing the workpiece and when the boring bar exits the workpiece after processing, the boring bar must keep entering and leaving at a specific angle each time, so when the spindle drives the borin...
