Description

Technical Field

[0001] The utility model belongs to the technical field of the detection of the run-out groove of the inner hole of a planetary gear, and particularly relates to a cutting device for a micro-elastic material forming sample. Background Art

[0002] As Figure 1 shown, for the inner hole of the planetary gear of a wind power raceway, the inner hole of the planetary gear is the outer ring of a bearing. It is difficult to verify the machining quality of the run-out groove (oil storage groove) of the 90.5° (tolerance 0 / -0.166°) inclined end face and the inner hole of the planetary gear (outer ring of the bearing), and the error of the detection result is relatively large; the structure of the run-out groove (oil storage groove) is irregular, and five characteristic elements (four straight lines and one arc) need to be captured for measurement, and the measured dimensions are small and precise.

[0003] Therefore, in order to make the detection result more accurate, a specially designed cutting device for materials is required to perform simulation-assisted detection. Content of the Utility Model

[0004] In order to solve the technical problem of the inconvenient detection of the run-out groove of the inner hole of the planetary gear in the background art, the purpose of the utility model is to provide a cutting device for micro-elastic materials, which can perform slicing detection on a micro-elastic material forming sample in the shape of the run-out groove of the inner hole of the planetary gear, thereby solving the above problems.

[0005] The technical solution for realizing the purpose of the utility model is: a cutting device for a micro-elastic material forming sample, comprising a base, a tool rest and a blade. The blade is fixed on the tool rest and installed towards the base, and the base is provided with a run-out groove body for placing the micro-elastic material forming sample; one end of the tool rest and one end of the base are hinged and rotatably installed, and the position where the tool rest rotates to the base intersects with the run-out groove body.

[0006] How to detect the run-out groove of the inner hole of the planetary gear. In this technical solution, micro-elastic material is filled and solidified in the run-out groove of the inner hole of the planetary gear to obtain a micro-elastic material forming sample in the shape of the run-out groove of the inner hole of the planetary gear. Then, the micro-elastic material forming sample is sliced and the slices are detected. Using this detection method, the detection data of various aspects of the run-out groove of the inner hole of the planetary gear can be obtained, especially the inclined end face angle A and its five key characteristic elements, namely four straight lines and one arc. Special equipment is required when slicing the micro-elastic material forming sample. Specifically, the run-out groove body on the base in the cutting device of this technical solution also belongs to the run-out groove, and its shape is the same as that of the run-out groove of the inner hole of the planetary gear, and its cross-sectional area is not less than the cross-sectional area of the micro-elastic material forming sample, which is convenient for placing the micro-elastic material forming sample into the run-out groove body on the base, and can effectively prevent the micro-elastic material forming sample from rotating or deflecting under pressure when the blade cuts the micro-elastic material forming sample during the downward movement of the tool holder, resulting in uneven slicing and inaccurate detection of the slices later. In addition, one end of the tool holder is hinged to the base, and the tool holder can only rotate within a fixed range of movement, without the problem of shaking or even deflecting during slicing caused by manual holding. Using the cutting device in this solution can effectively improve the slicing accuracy, thereby ensuring the accuracy of detecting the micro-elastic material forming sample by slicing, and solving the technical problem that the run-out groove of the inner hole of the planetary gear is inconvenient to detect. And this device has a simple structure, is easy to manufacture, has a low cost, and can be widely promoted and used. The micro-elastic material can be various materials, such as plasticine, etc.

[0007] Furthermore, the position where the tool holder rotates to on the base is perpendicular to the run-out groove body. It can also be understood that the tool holder is hinged to the base, and the tangent direction of the arc formed during its rotation is also perpendicular to the base. The advantage of this is that it can ensure that the slices of the micro-elastic material forming sample are cut vertically by the blade, which is the standard cross-sectional shape of the micro-elastic material forming sample, and it can be safely detected in all aspects to obtain accurate monitoring data.

[0008] Furthermore, the position where the tool holder rotates to on the base has a tool groove, and the tool groove intersects with the run-out groove body. Since the micro-elastic material forming sample is formed by fixing micro-elastic material such as plasticine, according to common sense and experience in life, after adding the tool groove, when the blade slices the micro-elastic material forming sample and then falls into the tool groove, there will be very little micro-elastic material sticking to the surface of the blade.

[0009] Further, one end of the base has a rotating shaft mounting portion, and the rotating shaft mounting portion has a rotating shaft mounting through hole. The end of the tool rest has a mounting hole, and the rotating shaft is mounted in the rotating shaft mounting through hole and the mounting hole. The tool rest is hingedly and rotatably mounted on the base through the cooperation of the rotating shaft, the rotating shaft mounting through hole and the mounting hole. And the over-travel groove body is parallel to the rotating shaft mounting portion, and the tool rest is perpendicular to the rotating shaft mounting portion. In this way, the tool rest always rotates perpendicular to the rotating shaft mounting portion, and when slicing the micro-elastic material forming sample, vertical slices can also be obtained.

[0010] Further, there are at least two tool rests. Mounting grooves are arranged at intervals on the rotating shaft mounting portion, and the ends of the tool rests are mounted in the mounting grooves. At least two tool rests can slice the strip-shaped micro-elastic material forming sample at the same time, improving the efficiency.

[0011] Further, it also includes a tool rest handle and a connecting rod. One end of the tool rest far from the rotating shaft mounting portion is connected to the tool rest handle through the connecting rod. After setting the tool rest handle, it is convenient for the operator to rotate the tool rest, and multiple tool rests can be connected to one tool rest handle through the connecting rod. In this way, holding one tool rest handle can drive multiple tool rests to slice at the same time.

[0012] Further, a buffer bracket for slowing down the rotation of the tool rest onto the base is also arranged on the base. When the tool rest handle falls close to the base, it can play a buffering role to prevent pinching hands.

[0013] Further, the position of the buffer bracket corresponds to the position of the connecting rod. The buffer bracket abuts against the connecting rod, and the over-travel groove body is arranged at one end of the base far from the buffer bracket. First, the height of the buffer bracket after contraction is close to the height of the rotating shaft mounting portion. That is to say, both ends of the blade on the tool rest can completely extend into the tool groove. The existence of the buffer bracket does not affect the slicing of the micro-elastic material forming sample by the blade, and the over-travel groove body is arranged at one end of the base close to the rotating shaft mounting portion to ensure that the slicing is completed and the shape and size of the slice are not affected.

[0014] Further, the buffer bracket includes a spring and a bearing portion with a bearing groove. The top and both sides of the bearing groove are open, and the connecting rod abuts in the bearing groove; the spring is installed between the base and the bearing portion. When the tool rest falls close to the base position, the connecting rod abuts into the bearing groove. Due to the open structure of the top and both sides of the bearing groove, which is similar to a semi-grasped hand shape, it can well bear the connecting rod, and then use the spring to play a buffering role.

[0015] Furthermore, the blade is fixed to the tool holder by screws, which is convenient for disassembly, and it is more convenient for disassembly, assembly, replacement and maintenance in the later stage.

[0016] Adopting the above technical solution, the utility model has the following beneficial effects:

[0017] (1) In this technical solution, after filling the run-out groove of the inner hole of the planetary gear with micro-elastic material and solidifying it, the formed sample of the micro-elastic material in the shape of the run-out groove of the inner hole of the planetary gear is detected. Furthermore, the detection purpose of the run-out groove of the inner hole of the planetary gear is solved. In order to better detect the formed sample of the micro-elastic material, a cutting device for the formed sample of the micro-elastic material is provided, which is convenient for detection after slicing;

[0018] (2) This cutting device is composed of a base, a tool holder and a blade, with a simple structure, convenient installation and low cost;

[0019] (3) In order to prevent the movement of the sample during slicing, a run-out groove body with a cross-section larger than that of the formed sample of the micro-elastic material is arranged on the base, and its shape is roughly matched with the sample, which can effectively prevent the movement of the sample and prevent the problems of uneven or skewed slicing;

[0020] (4) A tool groove corresponding to the blade is arranged on the base to prevent the micro-elastic material from sticking to the blade;

[0021] (5) A tool holder handle and a buffer bracket are further arranged to prevent the problem of pinching hands while conveniently rotating multiple tool holders;

[0022] (6) The blade is fixed to the tool holder by screws, which is convenient for disassembly and installation. Description of the Drawings

The blade 3 is fixed on the tool holder 2 and installed facing the base 1. The base 1 is provided with a run-out groove body 4 for placing the micro-elastic material forming sample 5. One end of the tool holder 2 and one end of the base 1 are hinged and rotatably installed. The position of the tool holder 2 on the base 1 intersects with the run-out groove body 4. Regarding how to detect the run-out groove of the inner hole of the planetary gear, in this technical solution, after the micro-elastic material is filled and solidified in the run-out groove of the inner hole of the planetary gear, a micro-elastic material forming sample 5 in the shape of the run-out groove of the inner hole of the planetary gear is obtained. Then, after slicing the micro-elastic material forming sample 5, the slices are detected. By using this detection method, the detection data of various aspects of the run-out groove of the inner hole of the planetary gear can be obtained, especially the inclined end face angle A and its five key characteristic elements, namely four straight lines and one arc 7( Figure 1 the thickened lines in). When slicing the micro-elastic material forming sample 5, special equipment is required. Specifically, the cross-sectional area of the run-out groove body 4 on the base 1 in the cutting device of this technical solution is not less than the cross-sectional area of the micro-elastic material forming sample 5. Placing the micro-elastic material forming sample 5 into the run-out groove body 4 on the base 1 can effectively prevent the micro-elastic material forming sample 5 from rotating or deflecting under pressure during the cutting of the micro-elastic material forming sample 5 by the blade 3 when the tool holder 2 drops, which may cause uneven slicing and then inaccurate detection of the slices. In addition, one end of the tool holder 2 is hingedly installed on the base 1. The tool holder 2 only rotates within a fixed range of movement and will not cause problems such as shaking and inaccurate slicing or even deflection like manual holding. By using the cutting device in this solution, the slicing accuracy can be effectively improved, and thus the accuracy of detecting the slices of the micro-elastic material forming sample 5 can be ensured, which solves the technical problem that the run-out groove of the inner hole of the planetary gear is inconvenient to detect. And this device has a simple structure, is easy to manufacture, has a low cost, and can be widely promoted and used. The micro-elastic material can be various materials, such as plasticine, etc.

[0029] Preferably, the position of the tool holder 2 on the base 1 intersects the run-out groove body 4 perpendicularly. It can also be understood that the tool holder 2 is hingedly installed on the base 1, and the tangent direction of the arc formed during its rotation is also perpendicular to the base 1. The advantage of this is that it can ensure that the slices of the micro-elastic material forming sample 5 are cut vertically by the blade 3, which is the standard cross-sectional shape of the micro-elastic material forming sample 5, and it can be safely detected in all aspects to obtain accurate monitoring data.

[0030] Preferably, the position where the tool rest 2 rotates to on the base 1 has a tool groove 8, and the tool groove 8 intersects with the over-travel groove body 4. Since the micro-elastic material forming sample 5 is formed after being fixed by a micro-elastic material such as plasticine, according to common sense in life, after adding the tool groove 8, when the blade 3 slices along the micro-elastic material forming sample 5 and then falls into the tool groove 8, there will be very little micro-elastic material sticking to the surface of the blade 3.

[0031] Preferably, one end of the base 1 has a rotating shaft installation part 9, and the rotating shaft installation part 9 has a rotating shaft installation through hole 10. The end of the tool rest 2 has an installation hole (not shown in the figure). The rotating shaft 17 is installed in the rotating shaft installation through hole 10 and the installation hole. The tool rest 2 is hingedly and rotationally installed on the base 1 through the cooperation of the rotating shaft 17, the rotating shaft installation through hole 10 and the installation hole. And the over-travel groove body 4 is parallel to the rotating shaft installation part 9, and the tool rest 2 is perpendicular to the rotating shaft installation part 9. In this way, the tool rest 2 always rotates perpendicular to the rotating shaft installation part 9, and when slicing the micro-elastic material forming sample 5, vertical slices can also be obtained.

[0032] Preferably, there are at least two tool rests 2. Installation grooves 11 are arranged at intervals on the rotating shaft installation part 9, and the ends of the tool rests 2 are installed in the installation grooves 11. At least two tool rests 2 can slice the strip-shaped micro-elastic material forming sample 5 at the same time, improving the efficiency.

[0033] Preferably, it further includes a tool rest handle 12 and a connecting rod 13. One end of the tool rest 2 far from the rotating shaft installation part 9 is connected to the tool rest handle 12 through the connecting rod 13. After setting the tool rest handle 12, it is convenient for the operator to rotate the tool rest 2, and multiple tool rests 2 can be connected to one tool rest handle 12 through the connecting rod 13. In this way, holding one tool rest handle 12 can drive multiple tool rests 2 to slice at the same time.

[0034] Preferably, a buffer bracket 14 is further provided on the base 1 for slowing down the rotation of the tool holder 2 onto the base 1. When the tool holder handle 12 drops close to the base 1, it can play a buffering role to prevent pinching hands. The position of the buffer bracket 14 corresponds to the position of the connecting rod 13. The buffer bracket 14 abuts against the connecting rod 13. The over-travel groove body 4 is arranged at one end of the base 1 away from the buffer bracket 14. First, the height of the buffer bracket 14 after contraction is close to the height of the rotating shaft mounting portion 9. That is to say, both ends of the blade 3 on the tool holder 2 can completely extend into the tool groove 8. The presence of the buffer bracket 14 does not affect the slicing of the micro-elastic material forming sample 5 by the blade 3. And the over-travel groove body 4 is arranged at one end of the base 1 close to the rotating shaft mounting portion 9 to ensure that the slicing is completed and the shape and size of the slice are not affected. The buffer bracket 14 includes a spring (not shown in the figure) and a bearing portion 16 with a bearing groove 15. The top and both sides of the bearing groove 15 are open. The connecting rod 13 abuts in the bearing groove 15. The spring is installed between the base 1 and the bearing portion 16. When the tool holder 2 drops to a position close to the base 1, the connecting rod 13 abuts into the bearing groove 15. Due to the open structure of the top and both sides of the bearing groove 15, which is similar to a semi-grasped hand shape, it can well hold the connecting rod 13, and then use the spring to play a buffering role.
