Description

Technical Field

[0001] The utility model relates to the technical field of three-face milling cutter detection, in particular to a high-precision three-face milling cutter disc detection table. Background Art

[0002] Three-edge milling cutter is abbreviated as three-edge milling cutter: all three edges have back angles, sharp edges, and light cutting. Three-edge milling cutter is a standard machine tool tool, usually used on horizontal milling machines, generally used for milling grooves and steps.

[0003] However, due to the manufacturing and installation accuracy errors of the blades and accessories, it is difficult to achieve high accuracy in the radial and axial dimensions. If the axial dimension accuracy is low, the width of the machined groove will change, and it will generally be larger; if the radial dimension accuracy is low, it means that the tool tip height is inconsistent, there is a large jump between the blades, the surface quality of the machined groove bottom is reduced, and the blade life is shortened.

[0004] In the prior art, three-sided and face milling cutters are generally only inspected through dimensional measurement, which makes it impossible to determine the actual working status of the three-sided and face milling cutters. This makes it inconvenient for designers to collect and provide feedback on the data of the three-sided and face milling cutters, thus affecting R&D efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-2, a high-precision three-sided milling cutter disc detection table, including a base 1, a lifting platform 2 is provided on one side of the base 1, a lifting rod is provided at the bottom of the lifting platform 2, the lifting rod is used to adjust the height of the lifting platform 2, the lifting platform 2 is slidably connected to the base 1, a sliding seat 3 is provided on the upper side of the lifting platform 2, a pushing screw 31 that passes through the sliding seat 3 is provided on the lifting platform 2, the sliding seat 3 is slidably connected to the top of the lifting platform 2, the pushing screw 31 and the sliding seat 3 are connected by a spiral pair, a tooling table 4 is provided on the upper side of the sliding seat 3, a workpiece to be processed on the tooling table 4 is fixed by a clamp, a feed screw 42 that passes through the tooling table 4 is provided on the sliding seat 3, the bottom of the tooling table 4 is slidably connected to the sliding seat 3, the feed screw 42 is connected to the tooling table 4 by a spiral pair, the pushing screw 31 and the feed screw 42 work, control and adjust the tooling table 4 to slide longitudinally or transversely, realize the change of the workpiece position, and a pressure sensor 41 corresponding to the feed screw 42 is provided on one side of the tooling table 4, which is used to detect the thrust exerted on the tooling table 4;

[0021] A cantilever 11 is provided on the upper side of the base 1, and a milling cutter assembly 5 is provided on the lower side of the cantilever 11. The milling cutter assembly 5 includes a spline shaft 51, a three-sided milling cutter disc 52 and a spline sleeve 53. A vibration sensor 54 corresponding to the spline sleeve 53 is provided at one end of the cantilever 11. A motor is provided on the inner side of the base 1. The motor output shaft is connected to the spline shaft 51. The spline shaft 51 and the spline sleeve 53 are correspondingly arranged. The motor controls the rotation of the spline shaft 51, thereby driving the rotation of the spline sleeve 53, thereby controlling the rotation of the three-sided milling cutter disc 52 for processing;

[0022] A detection computer is provided on the inner side of the base 1, and the pressure sensor 41 and the vibration sensor 54 are electrically connected to the detection computer for detecting and analyzing signals and analyzing the working status of the three-sided milling cutter 52. If the three-sided milling cutter 52 has high precision and the processing is stable during rotation and milling, the data measured by the pressure sensor 41 and the vibration sensor 54 should change smoothly and be in a stable data cycle. If abnormal changes occur, it means that there is a problem with the three-sided milling cutter 52 or the sample.

[0023] Working principle:

[0024] The inspector installs the three-face milling cutter disc 52 to be inspected on the spline sleeve 53, installs the sample on the tooling table 4, and controls the movement of the tooling table 4 through the lifting rod, the push screw 31 and the feed screw 42 to make the sample close to the three-face milling cutter disc 52;

[0025] When the three-edge milling cutter 52 is processing the sample, the vibration sensor 54 detects the vibration of the spline sleeve 53. If abnormal vibration occurs, it means that there is an unstable point when the three-edge milling cutter 52 is processing the sample, and dynamic detection is realized to assist in detecting the accuracy of the three-edge milling cutter 52.

[0026] Similarly, when the three-sided milling cutter 52 processes the sample, the sample is subjected to force, and the pressure is transmitted to the tooling table 4 and the feed screw 42. The pressure sensor 41 detects the force and determines whether the three-sided milling cutter 52 processes smoothly. If the blades are unevenly distributed or severely worn, the pressure sensor 41 detects that the force is not stable, indicating that the three-sided milling cutter 52 is abnormal in processing. The operator replaces different samples for further testing.

[0027] In addition, as needed, the service life and working reliability of the three-sided milling cutter disc 52 can be tested by simulating actual production conditions and using the three-sided milling cutter disc 52. Afterwards, the status of the three-sided milling cutter disc 52 can be tested to avoid the need to go directly to the production site for testing, thereby improving R&D feedback efficiency and reducing R&D costs.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
