Description

Technical Field

[0001] This invention relates to the field of positioning devices for gear production and processing, and specifically to a positioning device for gear production and processing. Background Technology

[0002] As a core component of mechanical transmission systems, gears are widely used in numerous fields such as automobiles, aerospace, engineering machinery, and precision instruments. Their machining accuracy directly determines the transmission efficiency, operational stability, noise level, and service life of mechanical equipment. In the gear manufacturing process, whether it is turning the gear blank, milling and grinding the teeth, or subsequent finishing processes, the positioning device is a key piece of equipment to ensure machining accuracy. Its core function is to accurately fix the gear blank or semi-finished product in the preset machining position, ensuring that the relative position of the machining tool and the gear always meets the process requirements, thereby avoiding quality problems such as tooth profile deviation, uneven tooth thickness, and out-of-tolerance tooth pitch caused by gear displacement or wobbling during the machining process.

[0003] Existing gear machining positioning devices have several shortcomings. First, they offer only a single positioning method, often only capable of positioning in a horizontal or vertical dimension. This makes it difficult to meet the requirements of high-precision machining for omnidirectional gear fixation, which can easily lead to gear misalignment during machining and affect the accuracy of key dimensions such as tooth profile and pitch. Second, they lack convenient positioning adjustment, making it cumbersome to adapt to gears of different sizes, with low adjustment efficiency. Furthermore, the positioning accuracy depends on the operator's experience, resulting in poor consistency. Third, they lack supporting cleaning functions, as metal shavings generated during gear machining can easily accumulate on the positioning surface and machining area. This not only affects the accuracy of subsequent positioning but may also scratch the gear surface, increasing the workload of subsequent cleaning processes. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a positioning device for gear production and processing, which can effectively solve the problems of single positioning dimension, cumbersome adjustment and lack of cleaning function in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a positioning device for gear manufacturing and processing, comprising a first base and a second base. The first base is fixedly connected to the upper surface of the second base. The first base has a cylindrical cavity. The inner top surface of the cylindrical cavity is rotatably connected to a first rotating shaft via a bearing. The inner top surface of the second base is rotatably connected to a second rotating shaft via a bearing. The second rotating shaft is rotatably connected to the bottom surface of the second base via a bearing. The first rotating shaft is rotatably connected to the bottom surface of the second rotating shaft via a bearing. A motor is fixedly connected to the bottom surface of the second base via a bracket.

The fourth bevel gear meshes with a third bevel gear. A movable seat is threaded onto the first threaded rod. A clamping seat is fixedly connected to the upper surface of the movable seat.

[0006] According to the above-mentioned positioning device for gear manufacturing, the vertical positioning component includes a second groove formed on the upper surface of the clamping seat, a sliding column slidably connected in the second groove, a threaded groove formed on the bottom surface of the sliding column, a second threaded rod threadedly connected in the threaded groove, the second threaded rod being rotatably connected to the bottom surface of the moving seat through a bearing, a third groove formed on the side wall of the sliding column, a lower pressure block slidably connected in the third groove, and a spring fixedly connected between the side wall of the lower pressure block and the inner wall of the third groove.

[0007] According to the above-mentioned positioning device for gear manufacturing, the transmission assembly includes a third rotating shaft rotatably connected to the inner bottom surface of a second base via a bearing. A driving wheel is fixedly connected to the second rotating shaft in the circumferential direction, and a driven wheel is fixedly connected to the third rotating shaft in the circumferential direction. A belt is sleeved between the driving wheel and the driven wheel.

[0008] According to the above-mentioned positioning device for gear production and processing, the cleaning component includes a collection cavity opened in a first base, a plurality of first filter holes are opened on the upper surface of the first base, a plurality of second filter holes are opened between the inner bottom surface of the first base and the second base, a cleaning groove is opened on the outer side wall of the first base, a sealing door is installed on the inner wall of the cleaning groove, and an exhaust fan blade is fixedly connected to the top of the third rotating shaft.

[0009] According to the above-mentioned positioning device for gear production and processing, multiple through slots are provided on the inner bottom surface of the multiple first grooves, the upper surface and bottom surface of the second base, and multiple second threaded rods respectively pass through the multiple through slots.

[0010] According to the aforementioned positioning device for gear manufacturing, the bottom ends of the plurality of second threaded rods and the bottom end of the first rotating shaft are all fixedly connected with knobs.

[0011] According to the above-mentioned positioning device for gear manufacturing, multiple driving wheels and driven wheels are located in a second base, and the diameter of the driving wheel is larger than the diameter of the driven wheel.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. This invention features a horizontal positioning component and a vertical positioning component. The horizontal positioning component drives a bevel gear transmission via a first rotating shaft, causing multiple clamping seats to slide synchronously to achieve gear centering and clamping. The vertical positioning component adjusts the height of the sliding column via a second threaded rod, and works with a retractable lower pressure block to press the top surface of the gear, forming an all-round positioning structure of "horizontal centering + vertical pressing". This effectively avoids gear offset and shaking during processing, significantly improves positioning accuracy, and ensures consistent processing dimensions.

[0014] 2. The present invention, through its transmission components, can utilize the power transmitted by the second rotating shaft to achieve power transmission through the cooperation of the driving wheel, driven wheel and belt. At the same time, it can achieve speed-increasing transmission by taking advantage of the diameter difference between the driving wheel and the driven wheel, thereby increasing the rotational speed of the third rotating shaft, providing sufficient and stable power support for the cleaning component, and ensuring the working efficiency of the cleaning component.

[0015] 3. The present invention, through its cleaning components, can draw metal shavings generated during gear processing into the collection chamber through the first filter hole under the negative pressure generated by the rotation of the exhaust fan blades. Combined with the second filter hole with a smaller aperture, it can achieve graded filtration and collection of shavings, avoiding the accumulation of shavings in the processing area and positioning surface. This not only ensures the accuracy of subsequent positioning but also prevents shavings from scratching the gear surface. At the same time, the cleaning groove and sealing door facilitate regular cleaning of shavings, reducing the amount of manual cleaning work and keeping the processing environment clean.

A spring 37 is fixedly connected between the side wall of the lower pressure block 36 and the inner wall of the third groove 35. Multiple through grooves 38 are provided on the inner bottom surface of multiple first grooves 21, the upper surface and bottom surface of the second base 11.

The transmission assembly 4 includes a third rotating shaft 41 rotatably connected to the inner bottom surface of the second base 11 via a bearing. The second rotating shaft 14 is circumferentially fixedly connected to a driving wheel 42, and the third rotating shaft 41 is circumferentially fixedly connected to a driven wheel 43. A belt 44 is sleeved between the driving wheel 42 and the driven wheel 43. Multiple driving wheels 42 and driven wheels 43 are located inside the second base 11. The diameter of the driving wheel 42 is larger than the diameter of the driven wheel 43. The cleaning component 5 includes a collection chamber 51 located inside a first base 1.

The diameter of the first filter hole 52 is larger than the diameter of the second filter hole 53.

[0022] The working principle of this invention is as follows: In use, the blank to be processed is placed between multiple clamping seats 25. According to the diameter specifications of the gear to be processed, the knob at the bottom of the first rotating shaft 13 is rotated, causing the first rotating shaft 13 to rotate. The third bevel gear 18 on the first rotating shaft 13 meshes with each fourth bevel gear 23, driving multiple first threaded rods 22 to rotate synchronously. The moving seat 24 slides radially along the first groove 21, causing the clamping seats 25 to move closer to or away from the center until the clamping seats 25 are in contact with the outer circumference of the gear, completing the lateral centering. If an unobstructed processing surface of the blank is not required during processing, multiple vertical centering... The positioning component 3 performs multi-dimensional clamping, thereby improving the stability of clamping and positioning. By rotating the knob at the bottom of the second threaded rod 34, the second threaded rod 34 rotates and drives the sliding column 32 to rise vertically along the second groove 31. After the lower pressure block 36 moves out of the second groove 31, it will pop out under the action of the spring 37. At this time, the lower pressure block 36 is raised and lowered again by rotating the second threaded rod 34 until the vertical clamping and positioning is completed. When it is necessary to retract, the lower pressure block 36 is manually pressed down so that it slides into the third groove 35 until it is fully inserted. Then, the sliding column 32 is retracted by rotating the second threaded rod 34. After positioning, the processing equipment is started to process the gears. At the same time, the motor 15 is started. The output end of the motor 15 drives the first bevel gear 16 to rotate. Through meshing with the second bevel gear 17, the second rotating shaft 14 is driven to rotate. The driving wheel 42 rotates with the second rotating shaft 14. Through the synchronous belt 44, the driven wheel 43 is driven to rotate, realizing speed-increasing transmission. The driven wheel 43 drives the third rotating shaft 41 to rotate. The exhaust fan blades 56 rotate synchronously to generate negative pressure. Under the action of negative pressure, the metal chips generated during processing are sucked into the collection chamber 51 through the first filter hole 52 on the upper surface of the first base 1. The inner bottom surface of the collection chamber 51 is equipped with a filter screen. The airflow flows from the first filter hole 52 to the second filter hole 53. The filter screen captures the chips in the airflow, thereby completing the chip cleaning. The sealing door 55 is to facilitate the cleaning of the collection chamber 51 and the filter screen, thereby avoiding chip accumulation. After the gear is processed, rotate shaft 13 in the reverse direction to move clamping seat 25 to slide in the reverse direction to release the gear, remove the processed gear, open the sealing door 55 on the outside of base 1, clean the metal shavings stored in collection chamber 51, close the sealing door 55 after cleaning, and reset the equipment to wait for the next processing.
