Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] In a typical embodiment of the present application, a spiral blade coaxiality detection device is provided, such as Figure 1-3 As shown, it includes a frame 1, on which are provided two sets of parallel first guide rails 2 and second guide rails 8. A dividing head 5 is provided at one end of the first guide rail 2 for clamping the central axis of the workpiece to be measured and driving the workpiece to rotate. A supporting device is installed at the other end of the first guide rail 2 for supporting the other end of the central axis; a slidingly connected dial indicator 12 is provided on the second guide rail 8, and the contact of the dial indicator 12 contacts the tangent point of the spiral blade of the workpiece to be measured; when the dial indicator 12 moves linearly along the spiral direction, each contact reads a dial indicator value, and by comparing the readings of each point, the maximum runout of the spiral blade in this direction can be obtained.

[0031] Specifically, if Figure 1 、 2 As shown, a first guide rail 2 and a second guide rail 8 are mounted parallel to the upper surface of the frame. A workpiece 13 to be inspected is mounted within the first guide rail 2 via a dividing head assembly and a support assembly. The workpiece 13 includes a central axis 1301 and a spiral blade 1302. This embodiment is intended to detect the coaxiality of the outermost end of the spiral blade 1302 in all directions. A dial indicator 12 for measurement is slidably disposed within the second guide rail 8. As the dial indicator 12 slides along the second guide rail 8, it sequentially contacts the vertical tangent points of the spiral blade, obtaining readings at each tangent point.

[0032] In this embodiment, the dividing head device includes a dividing head 5 and a dividing head connecting seat 4. Figure 1-2 As shown, the dividing head 5 is mounted on the dividing head connection base 4. The bottom end of the dividing head connection base 4 is fixedly connected to the first slider 3, which is slidably connected to the first guide rail 2. The position of the dividing head is adjusted by the first slider. This embodiment is suitable for testing center shafts of different lengths. The dividing head adopts an existing product on the market. The center shaft 1301 of the workpiece to be tested is clamped by a chuck and has a certain adjustment angle to meet the measurement of spiral blades with a certain taper. At the same time, it can drive the spiral blade 1302 to rotate, realizing the measurement of the spiral blade in different directions.

[0033] In this embodiment, the supporting device includes a top 6 and a top connecting seat 7, such as Figure 1 As shown, the tip 6 is mounted on the tip connection seat 7, which is detachably mounted on the first guide rail 2. The bottom end of the tip connection seat 7 is slidably connected to the first guide rail 2. The tip 6 is mounted at the end of the center shaft and is coaxially arranged with the dividing head 5. When the workpiece is installed, the tip 6 is inserted into the machining hole at the end of the center shaft to support and position the center shaft. At the same time, it is rotatably connected to the center shaft to facilitate adjustment of the measuring direction of the spiral blade. Figure 4As shown, the end of tip 6 closest to the workpiece is configured as a 60° cone, facilitating its insertion and tightening into the center shaft. A handle 601 is attached to the end of tip 6 away from center shaft 1301. Manually turning handle 601 moves the tip toward or away from the indexing head, thereby adjusting the outward extension of tip 6. This allows for adaptability to center shafts with varying hole specifications.

[0034] In other embodiments, when the center axis of some workpieces is not machined with a machining hole, the support device is configured as a V-block, and the V-block 14 is detachably mounted on the end of the workpiece away from the dividing head to support the center axis. Figure 3 、 5 As shown, V-block 14 is mounted at the end of the central shaft. It can be fixed on the first guide rail or slidably mounted on the first guide rail via a slider for adjustable position. The top of V-block 14 forms a V-shaped surface at a certain angle. Central shaft 1301 is placed on this V-shaped surface to provide support. This allows for coaxiality measurement of spiral blades with a certain taper, while maintaining the ability of the dividing head to drive the spiral blade to adjust the measurement direction.

[0035] In addition, in order to further improve the stability of the workpiece positioning, the support device also includes a V-shaped block 14, which is installed on the outside of the top and is used to support the end of the workpiece. Figure 3-4 As shown, the V-block 14 is fixedly installed at the end position of the central shaft. The top of the V-block 14 is a V-shaped surface with a certain angle, which is used to support the central shaft 1301 and can meet the coaxiality measurement of spiral blades with a certain taper. The V-block can be installed on the first guide rail through a slider to achieve position adjustment.

[0036] In this embodiment, Figure 1-3 As shown, the spiral blade's taper line 1303 is arranged parallel to the second guide rail 8, and a dial indicator 12 is mounted within the second guide rail 8. Specifically, the dial indicator 12 includes a contact 1201 that extends toward the workpiece and contacts the spiral blade's tangent point. The dial indicator 12 is fixedly mounted on a dial indicator base 11. The base connector 10 is fixedly connected to the bottom end of the base connector 10. The bottom end of the base connector 10 is provided with a second slider 9, which is slidably connected to the second guide rail 8 via the second slider 9.

[0037] The detection principle of this embodiment is:

[0038] By adjusting contact 12011 of dial indicator 12 so that it contacts the perpendicular tangent point of spiral blade 1302, while simultaneously moving dial indicator base 11 linearly along the pitch direction of spiral blade 1302, a value of dial indicator 12 is read at each contact point. The readings at each point are compared, and the difference between the maximum and minimum values ​​is the maximum runout of spiral blade 1302 in that direction. By rotating workpiece 13 by a certain angle using dividing head 5 and repeating the above method, the maximum runout of the spiral blade in each different direction can be determined. By comparing the size of several sets of differences in different directions, the maximum difference is determined to be the final runout of spiral blade 1302, which can be used to determine whether its coaxiality quality meets the requirements of the screw conveyor.

[0039] It should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Those skilled in the art will appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
