Description

Technical Field

[0001] The invention relates to the technical field of spiral bevel gear chamfering, and in particular to a spiral bevel gear automatic chamfering device. Background Art

[0002] Spiral bevel gears are a type of transmission component that can transmit smoothly and with low noise at a stable transmission ratio. Among various mechanical transmissions, spiral bevel gears have the highest transmission efficiency. Therefore, spiral bevel gears are widely used in many industries such as various mechanical processing equipment, engineering machinery, metallurgical equipment, etc.

[0003] During the production process of spiral bevel gear workpieces, after the blanks are cut and formed, they need to be polished, chamfered and deburred to achieve the required roughness. When grinding spiral bevel gears, most people use a handheld drill grinder to grind various parts of the spiral bevel gear. When grinding the arc surface of the ball gear, the handheld drill grinder is manually tilted at a certain angle, and the handheld drill grinder is pulled at a fixed angle to make a circular motion to achieve the grinding of the spiral bevel gear. This shaping method has high labor intensity, low shaping efficiency, and poor pass rate, which can easily lead to problems such as insufficient grinding or over-grinding of the spiral bevel gear.

[0004] In addition, most of the existing automatic chamfering devices can only perform chamfering, polishing, deburring and other operations on workpieces of specific regular shapes and sizes. The applicable objects are relatively few, and polishing debris is also easy to accumulate on the surface of the workbench, thus affecting the quality of gear processing; it is also difficult to remove burrs and polish in inaccessible areas such as complex inner surfaces and internal cross holes of the workpiece.

[0068] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] In the description of the present invention, it should be noted that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0070] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] To solve the above problems, Figure 1-16 The embodiment of the present invention provides a spiral bevel gear automatic chamfering device for chamfering a spiral bevel gear 7, wherein the spiral bevel gear automatic chamfering device comprises a mounting seat 5, a rotary table 3, a moving axis assembly 1, a rotary axis assembly 2, a cutting mechanism 6, a visual assembly 8 and a control system 4, wherein:

[0072] The mounting base 5 includes a base frame 51 and a back plate frame 52, wherein the back plate frame 52 is fixedly connected to one side of the base frame 51, wherein the base frame 51 serves as a supporting body and bears the main weight of the equipment, and the back plate frame 52 is located on the base frame 51, and is mainly used as a supporting mechanism for the moving axis assembly 1, the rotating axis assembly 2, the visual assembly 8 and the cutting mechanism 6, so as to facilitate the angle transformation of the moving axis assembly 1, the rotating axis assembly 2 and the cutting mechanism 6 in space.

[0073] The rotating worktable 3 is fixedly mounted on the base frame 51. The rotating worktable 3 can rotate and rise and fall on the base frame 51. The upper surface of the rotating worktable 3 is suitable for fixedly connecting the spiral bevel gear 7. In this way, when the spiral bevel gear 7 needs to be chamfered, the up and down movement of the rotating worktable 3 facilitates the approach of the cutting mechanism 6; the horizontal rotation of the rotating worktable 3 can improve the chamfering efficiency.

[0074] The movable shaft assembly 1 is slidably mounted on the back plate frame 52. The movable shaft assembly 1 is suitable for horizontally moving up and down on the back plate frame 52. The advantage of such an arrangement is that the spiral bevel gear 7 can be quickly reached by moving the movable shaft assembly 1 in the XYZ axis direction.

[0075] The rotating shaft assembly 2 is connected to the moving shaft assembly 1, and the rotating shaft assembly 2 is suitable for horizontal rotation relative to the moving shaft assembly 1. The advantage of this arrangement is that the freedom of the cutting mechanism 6 in the horizontal direction can be adjusted through the rotating shaft assembly 2, further realizing the adjustment needs of the chamfering direction.

[0076] The cutting mechanism 6 is connected to the lower side of the rotating shaft assembly 2. The cutting mechanism 6 is suitable for performing vertical rotational motion relative to the rotating shaft assembly 2, so that the cutting mechanism 6 can rotate in the vertical direction.

[0077] The visual component 8 is fixedly mounted on the back plate frame 52, and the visual component 8 is located on one side of the moving shaft component 1. The visual component 8 is arranged above the rotating worktable 3. After the spiral bevel gear 7 is loaded, the model and size of the spiral bevel gear 7 are judged by comparing the visual component 8 with the camera, and the visual component 8 communicates with the control system 4, calls the processing program of the corresponding product, and outputs the angle value at the same time, so as to realize automatic calibration of the tool.

[0078] The control system 4 is fixedly installed in the base frame 51 and is located on one side of the rotary table 3. The control system 4 is suitable for controlling the movement of the rotary table 3, the movable axis assembly 1, the rotating axis assembly 2 and the cutting mechanism 6 to complete the chamfering of the spiral bevel gear 7.

[0083] The indexing assembly 34 is fixedly connected to the spiral bevel gear 7 and the lower surface of the working turntable 31. When the cutting mechanism 6 moves to the vicinity of the spiral bevel gear 7, since the bevel teeth of the spiral bevel gear 7 are in a spiral structure, in order to be able to chamfer the spiral bevel teeth, it is also necessary to gradually adjust the indexing angle of the spiral bevel gear 7 when chamfering. At this time, the indexing assembly 34 can adjust the horizontal angle of the spiral bevel gear 7.
