Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0020] Such as figure 1 As shown, the detection device includes a tool magazine bracket 1, a sensor bracket 2, a laser displacement sensor A3, a linear bearing 4, a sliding support seat 5, a travel switch touch block 6, a travel switch 7, a guide shaft 8, a laser displacement sensor B9, data Acquisition card 10, industrial computer 11, cylindrical groove cam 12. Such as figure 1 and figure 2 It can be seen from the sectional view that the tool magazine support 1 is fixed on the tool magazine base, and the cylindrical grooved cam 12 is loaded into the bearing of the tool magazine bracket 1 so that it can rotate freely. Install the linear bearing 4 on the sliding support seat 5 and fix the above two parts together through the stop ring, and finally insert the linear bearing 4 into the guide rail shaft. The tool magazine support 1 can move forward and backward a...

Abstract

The invention discloses a bamboo hat magazine cutter feeding performance detecting method and a device, and belongs to the field of numerical control machine tool functional part performance detection. A sensor bracket is additionally mounted on a magazine body; two laser displacement sensors are fixed on a magazine bracket; optical paths of the two laser displacement sensors are parallel to the moving travel of a cutter; and travel switches are mounted at the travel starting point and ending point. A numerical control system controls a bamboo hat magazine to perform a cutter change action; at each time of advancing or retreating the cutter, the two laser displacement sensors can detect real-time displacements of connected slide support bases; and the two laser displacement sensors mutually verify the measured displacements. Acquired data is calculated, stored, processed and displayed on an industrial personal computer. The calculating result can reflect the cam curve (motion curves of cam driving and driven pieces) design defects and the cam motion characteristics. Some experimental data can be provided to magazine production enterprises.

Description

technical field [0001] The invention relates to a tool feeding performance detection method and device of a bucket hat tool magazine, and belongs to the field of performance detection of functional parts of numerical control machine tools. Background technique [0002] The tool magazine is an important functional part of the CNC machining center. The hat-style tool magazine is often used in small and medium-sized machining centers, and its tool change action is completed by the cooperation of the tool magazine action and the spindle action. When changing the tool, the spindle stops and brings the previous process tool down to the specified height, and the cutter head starts to feed the tool, that is, the empty claws of the cutter head move forward to grab the tool, the main shaft is lifted to pull out the previous process tool, and then the cutter head rotates to the subsequent process tool , the main shaft descends to install the tool, and then the cutter head returns to t...
