Description

Technical Field

[0001] This utility model relates to the technical field of machine tool precision testing devices, and in particular to a multi-prism device for detecting the rotation angle of a five-axis head. Background Technology

[0002] With the rapid development of manufacturing technology, the requirements for modern manufacturing equipment are becoming increasingly stringent. Five-axis CNC machine tools, as high-end manufacturing equipment, can meet the requirements of high-precision, multi-axis linkage machining of irregular curved surfaces, and have become a hot topic in high-end manufacturing equipment. The accuracy testing of five-axis CNC machine tools, especially the angular accuracy testing of the two rotary axes, is particularly important.

[0003] However, there is no good traditional method for detecting the rotation angle of a five-axis head. Before testing, it is necessary to spend a long time calibrating the prism and photoelectric collimator, which not only results in low measurement accuracy and long time consumption, but also leads to situations where the rotation angle is out of tolerance.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prism detection device for the rotation angle of a five-axis head, which aims to improve the existing technology that requires a long time to adjust the prism and photoelectric collimator before detection, resulting in low measurement accuracy, long time consumption, and the occurrence of rotation angle errors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-prism detection five-axis head rotation angle device, including a marble platform and a servo motor, wherein a sleeve is sleeved on the outer side of the output end of the servo motor, and a drive component is provided at the top of the servo motor;

[0007] The drive assembly includes a fixing plate fixedly connected to the top of the servo motor. A mounting cover is fixedly connected to the top of the fixing plate. A sealing ring is provided on the inner side wall of the mounting cover. A five-axis head reducer is also fixedly connected to the top of the mounting cover. A bearing is provided on the outer side of the middle part of the five-axis head reducer. A five-axis head flange is fixedly connected to the outer side wall of the five-axis head reducer. A connecting fixture is fixedly connected to the top of the five-axis head reducer. A prism body is fixedly connected to the top of the connecting fixture. A detection assembly is provided on the right side of the marble platform.

[0008] As a further description of the above technical solution:

[0009] The detection component includes a triangular support frame, which is located on the right side of the marble platform. A connecting plate is fixedly connected to the top of the triangular support frame, and the photoelectric collimator body is fixedly connected to the top of the connecting plate.

[0010] As a further description of the above technical solution:

[0011] A prism cover plate is fixedly connected to the top of the prism body.

[0012] As a further description of the above technical solution:

[0013] The prism cover plate has a central threaded connection with multiple evenly distributed fastening bolts.

[0014] As a further description of the above technical solution:

[0015] A fixing ring is fixedly connected to the top center of the marble platform, and multiple evenly distributed support plates are fixedly connected to the top of the fixing ring.

[0016] As a further description of the above technical solution:

[0017] The bottom of the marble platform is fixedly connected to a support frame, and the bottom of the support frame is fixedly connected to multiple evenly distributed electric telescopic rods.

[0018] As a further description of the above technical solution:

[0019] Each of the aforementioned electric telescopic rods has a shock-absorbing pad fixedly connected to its bottom end.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a five-axis head reducer is installed inside the connecting fixture fixed in the middle of the five-axis head flange, and a servo motor is connected to the bottom of the five-axis head reducer. At the same time, a multi-prism body is installed at the top of the connecting fixture. Under computer instructions, the servo motor will drive the five-axis head reducer to rotate by a corresponding angle, and the multi-prism body installed on the connecting fixture will also rotate by a corresponding angle at the same time. This achieves precise control of the rotation angle, which can effectively improve the measurement accuracy and avoid the product from having an out-of-tolerance rotation angle.

[0022] 2. In this utility model, a photoelectric collimator body is installed outside the marble platform. The photoelectric collimator body is fixed to the top of the tripod support frame by a connecting plate. By adjusting the height of the photoelectric collimator body, it is made to be on the same horizontal plane as the prism body, ensuring that the light emitted by the photoelectric collimator body is reflected back by the prism body. Then, the photoelectric collimator body will transmit the position of the reflected light and the position of the initially emitted light to the computer, thereby quickly determining whether the five-axis head precision deviation is due to the rotation angle deviation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model is provided: a multi-prism detection five-axis head rotation angle device, including a marble platform 1 and a servo motor 2. A sleeve 3 is sleeved on the outer side of the output end of the servo motor 2, and a drive component is provided on the top of the servo motor 2.

[0031] The drive assembly includes a fixed plate 4, which is fixedly connected to the top of the servo motor 2. A mounting cover 5 is fixedly connected to the top of the fixed plate 4. A sealing ring 6 is provided on the inner side wall of the mounting cover 5. A five-axis head reducer 7 is also fixedly connected to the top of the mounting cover 5. A bearing 8 is provided on the outer side of the middle part of the five-axis head reducer 7. A five-axis head flange 9 is fixedly connected to the outer side wall of the five-axis head reducer 7. A connecting fixture 10 is fixedly connected to the top of the five-axis head reducer 7. A multi-prism body 14 is fixedly connected to the top of the connecting fixture 10. A detection assembly is provided on the right side of the marble platform 1. A multi-prism cover plate 15 is fixedly connected to the top of the multi-prism body 14. Multiple evenly distributed fastening bolts 16 are threadedly connected to the middle part of the multi-prism cover plate 15. A fixing ring 17 is fixedly connected to the middle of the top of the marble platform 1. Multiple evenly distributed support plates 18 are fixedly connected to the top of the fixing ring 17.

[0032] Specifically, by fixing the prism cover plate 15 to the top of the prism body 14, and by threading multiple evenly distributed fastening bolts 16 in the middle of the prism cover plate 15, the prism body 14 can be fixed to the top of the connecting fixture 10, preventing the prism body 14 from moving or falling off.

[0033] Reference Figure 1 and Figure 3 The detection component includes a triangular support frame 11, which is located on the right side of the marble platform 1. A connecting plate 12 is fixedly connected to the top of the triangular support frame 11, and a photoelectric collimator body 13 is fixedly connected to the top of the connecting plate 12.

[0034] Specifically: The photoelectric collimator body 13 is connected to the triangular support frame 11 via the connecting plate 12, thereby facilitating the adjustment of the height of the photoelectric collimator body 13.

[0035] Reference Figure 1 and Figure 3 The bottom of the marble platform 1 is fixedly connected to a support frame 19, and the bottom of the support frame 19 is fixedly connected to multiple evenly distributed electric telescopic rods 20; the bottom of each of the multiple electric telescopic rods 20 is fixedly connected to a shock-absorbing pad 21.

[0036] Specifically, by fixing multiple evenly distributed electric telescopic rods 20 to the bottom of the support frame 19, and fixing shock-absorbing pads 21 to the bottom of the electric telescopic rods 20, the height of the marble platform 1 can be adjusted according to needs, and the shock-absorbing pads 21 can reduce the interference of external vibrations on the equipment.

[0037] It should be noted that the servo motor 2, the five-axis head reducer 7, and the photoelectric collimator body 13 are all well-known or known to those skilled in the art, and therefore will not be described here.

[0038] Working principle: The device has a five-axis head reducer 7 installed inside the connecting fixture 10 fixed in the middle of the five-axis head flange 9, and a servo motor 2 connected to the bottom of the five-axis head reducer 7. At the same time, a multi-prism body 14 is installed at the top of the connecting fixture 10. Under the computer command, the servo motor 2 will drive the five-axis head reducer 7 to rotate by a corresponding angle, and the multi-prism body 14 installed on the connecting fixture 10 will also rotate by a corresponding angle at the same time. This achieves precise control of the rotation angle, which can effectively improve the measurement accuracy and avoid the product from having an out-of-tolerance rotation angle.

[0039] Meanwhile, an optoelectronic collimator body 13 is installed outside the marble platform 1. The optoelectronic collimator body 13 is fixed to the top of the tripod support frame 11 via a connecting plate 12. By adjusting the height of the optoelectronic collimator body 13, it is made to be on the same horizontal plane as the prism body 14, ensuring that the light emitted by the optoelectronic collimator body 13 is reflected back by the prism body 14. Then, the optoelectronic collimator body 13 transmits the position of the reflected light and the position of the initially emitted light to the computer, thereby quickly determining whether the five-axis head accuracy deviation is due to the rotation angle deviation. In addition, multiple evenly distributed electric telescopic rods 20 are fixedly connected to the bottom of the support frame 19, and shock-absorbing pads 21 are fixed to the bottom of the electric telescopic rods 20. Thus, the height of the marble platform 1 can be adjusted as needed, and the shock-absorbing pads 21 can reduce the interference of external vibrations on the equipment.
