In general, the machining reference plane 202 is a horizontal plane.

Referring to fig. 6A, S1: the transposition measurement and control device 100 of the working turntable of the horizontal boring and milling machine is placed on the working turntable 201 of the horizontal boring and milling machine. The adjustment is such that the surface 14 of the angular scale of the indexing dial is parallel or coplanar to the machining reference plane 202. The working turret 201 may not be planar, and may be a part to which the working turret 201 is fixedly connected, or may be a part of a part to be machined (the part to be machined is fixedly connected to the working turret 201). If the machining reference plane 202 is a horizontal plane, it is only necessary to calibrate the surface 14 of the angle scale of the index dial to be horizontal. In this initial position, the indicator line 2 is adjusted, the spindle axis 204 is parallel or collinear with the indicator line 2, and the indicator line 2 is indicated as a first scale. Typically, the indicator line 2 is pointed at the 0 ° graduation line to facilitate subsequent calculations. If the indication line 2 points to the 0 ° graduation line, the index scale 1 can be rotated by rotating the whole support body 5 and the component fixed or stationary relative to the support body 5, so as to adjust the indication line 2 to be relatively parallel or collinear with the spindle axis 204 (i.e. the included angle therebetween is 0 °), and as shown in fig. 6A, keeping the surface 14 parallel or coplanar with the processing reference plane 202 actually means that the angle corresponding to the projection of the surface 14 toward the processing reference plane 202 is unchanged (orthographic projection). After the adjustment is in place, the relative position of the horizontal boring and milling machine working turntable indexing measurement and control device 100 and the horizontal boring and milling machine working turntable 201 is unchanged, and the static friction force between the contact point, namely the screw 66 and the working turntable 201, is relied on.

Referring to fig. 6B, S2: the indication line 2 is rotated by a set angle (e.g., -72 ° as shown in fig. 6B), i.e., the indication line 2 is rotated to a second scale (e.g., -72 ° as shown in fig. 6B) which is equal to the first scale plus the set angle (e.g., -72 ° as shown in fig. 6B because the first scale is 0 ° in fig. 6A).

Referring to fig. 6C, S3: the working turret 201 is rotated until the spindle axis 204 is again parallel or collinear with the indicator line 2 (angle 0 °). The spindle axis 204 may be obtained by a cylinder with its circumscribed surface parallel to the spindle axis 204, or by a cylinder with a cubic head superimposed, with the upper surface of the cube horizontal and the side surfaces in a vertical plane parallel to the spindle axis 204. However, the indication line 2 being parallel to the vertical plane may indicate that the indication line 2 is parallel to or collinear with the main axis 204, and the included angle therebetween is 0 °.

Referring to fig. 7A-7D, the relevant angles are translated to positions where the spindle axis 204 can be measured using the principle of homography. The part 300 to be machined is shown having a machined surface 301 and a surface 302 to be machined. By changing fig. 7B to fig. 7D, the principle of the same azimuth angle of fig. 7A and 7C is shown, and accurate control of the indexing can be realized. Fig. 7A shows the relationship of the three lines L1, L2, L3, and the relationship of the three lines to the table outer reference line Lref before the rotation of the working turntable 201. Correspondingly, fig. 7B shows the machined surface 301 aligned with the spindle axis 204 of the tool 203. Fig. 7C shows the relationship of the three lines L1, L2, L3, and the relationship of the three lines to the table outer reference line Lref after the rotation of the working turntable 201. After the working table is rotated, the geometric relationship among three lines of L1, L2 and L3 is unchanged; any line of L1, L2, L3 has the same relationship change with the reference line, and α and β are equal. Correspondingly, fig. 7D shows the situation in which the surface 302 to be machined is aligned with the spindle axis 204 of the tool 203, i.e. when the rotation of the working turret 201 has been completed.

The invention provides a second embodiment of the transposition measurement and control method for the working turntable of the horizontal boring and milling machine.

Referring to fig. 6A, 6B and 6C, to further increase the convenience of the test by making the indicator line 2 parallel or collinear with the spindle axis 204, the indicator line 2 is translated to the measuring rod 4. The method for measuring and controlling the indexing of the working rotary table of the horizontal boring and milling machine by using the device 100 for measuring and controlling the indexing of the working rotary table of the horizontal boring and milling machine with the measuring rod 4, wherein the working rotary table 201 of the horizontal boring and milling machine is provided with a processing reference plane 202, and the horizontal boring and milling machine is provided with a main shaft axis 204 of a cutter comprises the following steps, and compared with the first embodiment of the method, the method mainly comprises the step that the measuring rod 4 replaces the measuring indication line 2 in the method of the first embodiment.

Referring to fig. 6A, S1: the horizontal boring and milling machine working turntable transposition measurement and control device 100 is placed on the horizontal boring and milling machine working turntable 201. The adjustment is such that the surface 14 of the angular scale of the indexing dial is parallel or coplanar to the machining reference plane 202. In this initial position, the measuring rod 4 is adjusted, the spindle axis 204 is parallel or collinear with the measuring rod 4, and the indicator line 2 indicates a first scale.

Referring to fig. 6B, S2: rotating the indicating line 2 by a set angle, namely rotating the indicating line 2 to a second scale which is equal to the first scale plus the set angle;

referring to fig. 6C, S3: the working turret 201 is rotated until the spindle axis 204 is again parallel or collinear with the measuring rod 4.

If the measuring rod 4 has the detecting surface 41, the detecting surface 41 is also a vertical surface, a cube can be arranged at the end of a cylinder clamped coaxially at the spindle axis 204, and the upper plane of the cube is horizontal, so that the vertical surface of the cube parallel to the spindle axis 204 is parallel or coplanar (the included angle is 0 °) with the detecting surface 41, that is, the spindle axis 204 and the measuring rod 4 are set to be parallel or collinear with each other. Still further, the degree of parallelism between two faces can be measured with the dial gauge 400 using a vertical face of a cube parallel to the spindle axis 204 as a reference face.

S1: the transposition measurement and control device 100 of the working turntable of the horizontal boring and milling machine is placed on the working turntable 201 of the horizontal boring and milling machine. The adjustment is such that the surface 14 of the angular scale of the indexing dial is parallel or coplanar to the machining reference plane 202. In this initial position, the rotatable cap 32 is rotated so that the light ray 2, indicated as the first scale, is parallel or collinear with the spindle axis 204. Of course, similar to the above, the movement is relative, and the same technical scheme is that the light emitted by the rotatable scale cover indicates 0 °, that is, the first scale is 0 ° by rotating the placing angle of the horizontal boring and milling machine rotary table transposition measurement and control device 100. Or, the first scale is 0 ° and is one of the special technical solutions.

S2: rotating the rotatable cap 32 sets the angle, i.e. rotating the light 2 to a second scale equal to the first scale plus the set angle.

S3: the work turret 201 is rotated until the spindle axis 204 is again parallel or collinear with the ray 2.

Of course, the third embodiment of the method provided by the present invention can also be implemented in combination with the second embodiment, that is, on the basis of the third embodiment, whether the relative position between the spindle axis 204 and the light ray 2 forms an included angle of 0 ° is converted into a measurement of the relative position between the measuring rod 4 and the spindle axis 204.
