Description
Technical Field
[0001] This utility model relates to the field of gear processing technology, and in particular to a gear shaving machine for gear processing. Background Technology
[0002] Gear shaving is a crucial step in improving gear precision and surface quality, its core being the removal of trace amounts of metal through the meshing of a shaving cutter with the gear. Traditional gear shaving machines have significant shortcomings in clamping and positioning, cooling and chip removal, and chip cleaning: Cooling and chip removal are ineffective; the chips generated during shaving easily mix with the coolant and adhere to the machine tool interior, especially clogging narrow chip removal channels, requiring frequent shutdowns for cleaning. Existing spray systems mostly use fixed-angle spraying, making it difficult to accurately cover the shaving contact area, resulting in coolant waste and ineffective suppression of cutting heat; automated cleaning capabilities are lacking: long-term chip accumulation not only reduces the cleanliness of the machining environment but may also enter transmission components, causing wear. Traditional solutions rely on manual cleaning or simple scraper structures, resulting in incomplete cleaning and increased maintenance costs. Therefore, we propose a gear shaving machine for gear machining. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a gear shaving machine for gear processing, comprising a gear shaving machine body and a mounting frame. The mounting frame is a "U"-shaped block and is installed inside the gear shaving machine body. The mounting frame is a "U"-shaped block, and a guide hole is provided on the bottom side of the mounting frame. The guide hole is a funnel-shaped through hole. A guide cylinder is fixedly installed on the bottom side of the mounting frame corresponding to the position of the guide hole. A rotating cylinder is rotatably installed on the outer side of the guide cylinder, and two cleaning rods are fixedly installed on the inner side of the rotating cylinder. Two movable cavities are symmetrically opened on the inner side of the mounting frame. Movable blocks are slidably installed inside the two movable cavities. A rotating extrusion cone is provided on one side of each of the two movable blocks, and an expansion sleeve is provided on one side of each of the two extrusion cones. A processing gear is engaged on the outer side of the expansion sleeve. A mounting hole is provided on the side of the mounting frame, and a water spray pipe is rotatably installed inside the mounting hole. A water spray head is fixedly installed at one end of the water spray pipe, and the water spray pipe and the water spray head are arranged perpendicularly.
[0005] Preferably, the movable block has a toothed groove on its side, and a first rotary motor is fixedly installed on the side of the mounting bracket at the position corresponding to the toothed groove. A first rotary gear that meshes with the toothed groove is fixedly installed at the output end of the first rotary motor.
[0006] Preferably, the movable block has an installation cavity on one side corresponding to the extrusion cone, and a fixed fourth rotary motor is installed inside the installation cavity, with the extrusion cone fixedly installed at the output end of the fourth rotary motor.
[0007] Preferably, the mounting frame has a rotating cavity on its bottom side, a rotating ring is rotatably mounted inside the rotating cavity, a rotating cylinder is fixedly mounted on the lower end of the rotating ring, a fixed first adapter tooth is provided on the outer side of the rotating cylinder, a second rotating motor is fixedly mounted on the bottom side of the mounting frame, and a second rotating gear that meshes with the rotating cylinder is fixedly mounted on the lower end of the second rotating motor.
[0008] Preferably, a fixing rod is fixedly installed on the side of the mounting bracket, and a connecting cylinder is fixedly installed on the side of the fixing rod. The connecting cylinder is sleeved on one end of the water spray pipe. A fixed second adapter tooth is provided on the outer side of the water spray pipe.

[0009] Preferably, the bottom side of the mounting bracket is an inclined surface, and the guide hole is a funnel-shaped through hole with a large opening at the top and a small opening at the bottom.
[0010] Preferably, a dust cover is fixedly installed on the side of the mounting bracket corresponding to the position of the movable block. The dust cover is a hollow rectangular cover. Beneficial effects
[0011] This utility model provides a gear shaving machine for gear processing. It has the following beneficial effects:
[0012] (1) In this gear shaving machine, the water spray pipe is driven by a third rotary motor to mesh with the second adapter gear, achieving stepless adjustment of the water spray head angle and precisely covering the shaving contact area. The guide hole adopts a funnel-shaped through-hole design, which, together with the linkage of the rotating cylinder and the cleaning rod, forms a dual-mode chip removal of "flushing + mechanical cleaning". The water spray head can dynamically adjust the spray direction according to the position of the shaving blade, reducing coolant waste and enhancing the cooling effect of the cutting area. The inclined bottom surface of the guide hole works in conjunction with the rotating cleaning rod to use centrifugal force to quickly discharge iron filings along the guide cylinder. At the same time, the rotating cleaning rod scrapes off the adhering residue, avoiding channel blockage. This design significantly reduces the frequency of manual intervention and improves continuous processing efficiency.
[0013] (2) The gear shaving machine for this gear processing utilizes a linkage design of a movable block, an extrusion cone, and an expanding sleeve. A first rotary motor drives the gear tooth groove to achieve lateral movement of the movable block, causing the two extrusion cones to simultaneously extrude the two ends of the expanding sleeve, resulting in uniform radial expansion and rapid clamping of the processed gear. The elastic deformation characteristics of the expanding sleeve are adapted to gears of different inner diameters. After clamping, a fourth rotary motor directly drives the extrusion cone to rotate, causing the gear to precisely mesh with the shaving cutter, avoiding the secondary positioning errors of traditional fixtures. This structure simplifies the clamping process, improves clamping stability, and ensures that the gear does not move axially during the shaving process. Attached Figure Description

[0024] like Figures 1-5 As shown, a gear shaving machine includes a shaving machine body and a mounting frame 1. The mounting frame 1 is a U-shaped block and is installed inside the shaving machine body. A guide hole 2, which is a funnel-shaped through hole, is provided on the bottom side of the mounting frame 1. A guide cylinder 3 is fixedly installed on the bottom side of the mounting frame 1 corresponding to the position of the guide hole 2. A rotating cylinder 4 is rotatably installed on the outer side of the guide cylinder 3, and two cleaning rods 5 are fixedly installed on the inner side. Two movable cavities 9 are symmetrically opened on the inner side of the mounting frame 1, and movable blocks 10 are slidably installed inside each of the two movable cavities 9. Each of the two movable blocks 10 has a rotating extrusion cone 13 on one side corresponding to the other. Each of the two extrusion cones 13 has a tension sleeve 14 on one side corresponding to the other. The tension sleeve 14 has a double-end extrusion and tensioning structure, which is existing technology and will not be described in detail here. A machining gear 15 is engaged on the outer side of the tension sleeve 14. A mounting hole 6 is provided on the side of the mounting bracket 1. A water spray pipe 7 is rotatably mounted inside the mounting hole 6. A water spray head 8 is fixedly mounted at one end of the water spray pipe 7. The water spray pipe 7 and the water spray head 8 are perpendicular. When the machining gear 15 is placed inside the tension sleeve 14 and tensioned, the two movable blocks 10 are moved. The machine tool 10 drives two extrusion cones 13 to continue extruding the two ends of the expansion sleeve 14. Then, the extrusion cones 13 rotate, causing the expansion sleeve 14 to rotate along with the machining gear 15. As the gear 15 rotates, it contacts the shaving cutter to shave its teeth. At this time, the water spray pipe 7 is rotated, causing the water spray head 8 to rotate and position itself so that the shaving cutter contacts the machining gear 15, spraying out coolant. The coolant, mixed with metal filings, falls through the guide hole 2 and the guide cylinder 3 and moves out. While cleaning the inside of the machine tool, the water spray pipe 7 is rotated. The water spray pipe 7 drives the water spray head 8 to move downwards. At this time, the water spray head 8 sprays out coolant, which flows along the guide hole 2 and the guide cylinder 3. At this time, the rotating cylinder 4 is rotated, which drives the cleaning rod 5 to rotate. The rotating cleaning rod 5 cleans the iron filings adhering to the surface of the guide hole 2 and the guide cylinder 3. The bottom side of the mounting bracket 1 is an inclined surface. The guide hole 2 is a funnel-shaped through hole with a larger opening at the top and a smaller opening at the bottom, which facilitates the discharge of impurities. A dust cover 19 is fixedly installed on the side of the mounting bracket 1 at the position corresponding to the movable block 10. The dust cover 19 is a hollow rectangular cover.
[0025] The movable block 10 has a toothed groove 16 on its side. A first rotary motor 17 is fixedly installed on the side of the mounting bracket 1 at the position corresponding to the toothed groove 16. A first rotary gear 18 that meshes with the toothed groove 16 is fixedly installed at the output end of the first rotary motor 17. The first rotary motor 17 drives the first rotary gear 18 to rotate. The first rotary gear 18 meshes with the toothed groove 16 and drives the movable block 10 to move laterally. The movable block 10 has a mounting cavity 11 on its side corresponding to the extrusion cone 13. A fixed fourth rotary motor 12 is installed inside the mounting cavity 11. The extrusion cone 13 is fixedly installed at the output end of the fourth rotary motor 12. The fourth rotary motor 12 drives the extrusion cone 13 to rotate. The extrusion cone 13 drives the expansion sleeve 14 and the processing gear 15 to rotate.
[0026] A rotating cavity 20 is provided on the bottom side of the mounting frame 1. A rotating ring 21 is rotatably mounted inside the rotating cavity 20. A rotating cylinder 4 is fixedly mounted on the lower end of the rotating ring 21. A fixed first adapter tooth 22 is provided on the outer side of the rotating cylinder 4. A second rotating motor 23 is fixedly mounted on the bottom side of the mounting frame 1. A second rotating gear 24 that meshes with the rotating cylinder 4 is fixedly mounted on the lower end of the second rotating motor 23. When the second rotating motor 23 is started, it drives the second rotating gear 24 to rotate. The second rotating gear 24 drives the rotating cylinder 4 to rotate through the first adapter tooth 22. The rotating cylinder 4 drives the cleaning rod 5 to rotate. The side of the mounting frame 1... A fixing rod 29 is fixedly installed, and a connecting cylinder 28 is fixedly installed on the side of the fixing rod 29. The connecting cylinder 28 is sleeved on one end of the water spray pipe 7. A fixed second adapter tooth 25 is provided on the outside of the water spray pipe 7. A third rotary motor 26 is fixedly installed on the side of the mounting bracket 1. A third rotary gear 27 that meshes with the second adapter tooth 25 is fixedly installed at the output end of the third rotary motor 26. (When the third rotary motor 26 is started, the third rotary motor 26 drives the third rotary gear 27 to rotate. The third rotary gear 27 drives the water spray pipe 7 to rotate through the second adapter tooth 25. The water spray pipe 7 drives the mounting hole 6 to rotate to change the water spray angle of the mounting hole 6.)
[0027] The working principle of this utility model:
[0028] In use, the processing gear 15 is placed inside the expansion sleeve 14. The first rotary motor 17 is started, driving the first rotary gear 18 to mesh with the tooth groove 16 on the side of the movable block 10, causing the two movable blocks 10 to move towards the center, pushing the extrusion cone 13 to press the two ends of the expansion sleeve 14 to make it expand radially, thus completing the gear fastening. Gear shaving: The fourth rotary motor 12 drives the extrusion cone 13 to rotate, causing the expansion sleeve 14 and the processing gear 15 to rotate synchronously and contact the shaving cutter for cutting; the third rotary motor 26 adjusts the water spray head 8 to the shaving contact area, spraying coolant to cool down and flush away iron filings. The iron filings flow into the guide cylinder 3 through the guide hole 2 with the coolant. Cleaning and maintenance: After processing, the second rotary motor 23 drives the rotating cylinder 4 to rotate through the first adapter tooth 22, causing the cleaning rod 5 to rotate and scrape away the iron filings remaining in the guide hole 2 and the inner wall of the guide cylinder 3; the water spray head 8 switches to the wide-angle spray mode, cooperating with the movement of the cleaning rod 5 to achieve channel self-cleaning.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
