Embodiment 1

[0075] like figure 1 As shown, a drilling force detection device includes a circular support base 2 , a first pressure sensor 3 , a support disc 4 , a bearing 5 , and a clamping platform 6 .

[0076] like Figure 5 and Figure 6 As shown, the circular support seat 2 is a cylindrical structure, and a square through hole 16 is opened in the middle along the axial direction. A cover plate 17 is provided at the bottom of the square through hole 16 . The first pressure sensor 3 is disposed in the square through hole 16 and fixed on the cover plate 17 . The cover plate 17 covering the square through hole 16 can ensure the airtightness of the lower plane of the circular support base 2 . The inner wall of the through hole 16 just fits the outer wall of the first pressure sensor 3 .

[0077] like figure 1 , 5 As shown in , 6, four arc-shaped baffles are evenly and fixedly distributed along the center of the circle on the top of the circular support seat 2, and the four arc-shape...

Embodiment 2

[0098] On the basis of Embodiment 1, in order to be more convenient to fix, the square groove circular seat 34 is also provided with screw mandrel locking and fixing mechanism, and screw mandrel locking and fixing mechanism is provided with four altogether, respectively with the 3rd screw mandrel 25 and the 4th screw mandrel. Screw rod 43 is connected.

[0099] like Figure 7 and Figure 12 As shown, the screw rod locking and fixing mechanism is provided with four including fixed block 24 / 41, polished rod 39, position springs 30, 38, one end of polished rod 39 is fixed on the fixed block 24 / 41, and a boss is provided on the polished rod 39 The position springs 30, 38 are sleeved on the polished rod 39 and resist the boss, and the other end of the polished rod 39 is telescopically slidably connected with the square groove circular seat 34 sides. A toothed circular hole 42 is opened on the fixing block 24 / 41 , and the other end of the third screw rod 25 and the other end of ...

Embodiment 3

[0105]A drilling force detection device is composed of a cross slide 1, a circular support seat 2, a first pressure sensor 3, a support disc 4, a bearing 5 and a clamping platform 6. The cross slide 1, the circular support seat 2, the first pressure sensor 3, the support disc 4, the bearing 5, and the clamping platform 6 are installed and fixed sequentially from bottom to top.

[0106] Cross slide table 1 is made up of lower track 7, the first screw mandrel 8, the first rocking handle 9, the first cross track 10, upper track 11, the second screw mandrel 12, the second rocking handle 13. The first screw mandrel 8 helically passes through the screw screw hole of the lower track 7, the first rocking handle 9 is installed on the end of the first screw mandrel 8, shaking the first rocking handle 9 can drive the first screw mandrel 8 to rotate. There is a protruding first cylinder 14 in the middle of the lower end of the first cross track 10. A screw hole is opened from the side of ...

Abstract

The invention discloses a drilling force detection device and relates to the technical field of drilling force analysis. The center of a circular supporting base is provided with a pressure sensor, asupporting circular disk capable of rotating relative to the circular supporting base and a clamping platform. The outer side of the clamping platform is provided with a pressure sensor, and a pressure sensor in the clamping direction is arranged in the clamping platform. Accordingly, the drilling force detection device can implement pressure detection on a tool in three directions. When drillingis implemented, the drilling force detection device can detect axial force, radial force and tangential force through the three pressure sensors. The drilling force detection device is further provided with a laser positioning and clamping fixing device. Adjustment on the device and clamping on the tool can be realized conveniently. The drilling force detection device provides a convenient hardware platform for drilling force detection. In addition, the invention further provides a detection method based on the drilling force detection device. Through the drilling force detection device and detection method, the positioning, clamping and data detection efficiency in the detection process can be improved.

Description

technical field [0001] The invention relates to the technical field of drilling force analysis, in particular to a drilling force detection device and a detection method thereof. Background technique [0002] Hole drilling technology is widely used in various fields of precision machining such as aviation and aerospace, as well as the production of conventional equipment such as molds and medical equipment. Drilling is simple in form, high in processing efficiency, and good in dimensional accuracy, so drilling is one of the most commonly used hole processing methods in the field of mechanical processing. [0003] Drilling is a cutting method in a closed or semi-closed state. It has the characteristics of not being able to directly observe the cutting condition of the drill bit, cutting heat is not easy to spread, chips are not easy to discharge, and the rigidity of the process system is poor. The processing process is very difficult. Unstable, there are many unfavorable fac...
