Description

Technical Field

[0001] This invention relates to the field of worm gear machining technology, and more particularly to a worm gear tooth machining device. Background Technology

[0002] Worm gear transmission structures are widely used in the field of mechanical transmission. The teeth on existing worm gears are made by hobbing or cutting the teeth and then finishing them by shaving, honing or grinding, which requires the use of processing equipment.

[0003] Current worm gear machining devices, such as the worm gear tooth machining device disclosed in Chinese Patent Publication No. CN112935416B, require continuous replenishment of lubricating oil to the machining area during worm gear tooth machining. However, during the replenishment process, the lubricating oil often only fills a limited area machined by the worm cutter, failing to cover the entire machining range. This not only leads to insufficient lubrication in the outer machining area of ​​the worm cutter, which can easily cause machining errors, but also results in excessive lubrication in the central machining area of ​​the worm cutter, leading to over-lubrication and compromising the machining accuracy of the worm gear teeth. Therefore, this invention proposes a worm gear tooth machining device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a worm gear tooth processing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A worm gear gear machining device includes a fixed frame, a support frame, a machining box, and a protective shell. The support frame is fixedly mounted on the top of the fixed frame, the machining box is fixedly connected to one side of the support frame, and the protective shell is fixedly mounted on one side of the machining box. A machining section is provided inside the machining box. The machining part includes a rotating rod and a worm cutter, wherein the worm cutter is fixedly mounted on the rotating rod. The machining part drives the worm cutter to rotate by rotating the rotating rod, and the worm cutter rotates to cut the worm wheel to be machined. The protective shell is equipped with an oil spraying swing component, which consists of an oil spraying part and a swinging part. The oil spraying part includes a slider and an oil outlet pipe. The oil spraying part drives the slider laterally along the direction of the rotating rod to squeeze the lubricating oil and then spray it out from the oil outlet pipe. The swinging part includes a nozzle, which is driven by the rotation of a rotating rod to make a back-and-forth arc swinging motion along the direction of the rotating rod. The support frame is equipped with a second oil tank, and the interior of the second oil tank is equipped with an adsorption section. The adsorption section uses electromagnets to adsorb debris inside the lubricating oil, and then releases and recovers the debris by rotating the electromagnets to cut off the power.

[0006] Preferably, the processing unit further includes a processing base and a worm gear. The processing unit drives the worm cutter to rotate laterally via a rotating rod, thereby driving the worm gear and the processing base to rotate slowly vertically inside the processing box through the meshing of the worm cutter and the worm gear to be processed.

[0007] Preferably, the oil outlet pipe is fixedly installed on the top of the nozzle, and the oil outlet pipe is interconnected with the nozzle. The oil outlet pipe is equipped with a one-way valve that faces the nozzle in one direction, and the oil outlet pipe is composed of a flexible and foldable hose structure.

[0008] Preferably, the adsorption section includes a partition plate that divides the interior of the second oil tank into a filtration chamber and a recovery chamber, wherein the recovery port is connected to the recovery chamber. An oil passage hole is provided on the partition plate, and a matching oil passage mesh is fixedly installed in the oil passage hole.

[0009] Preferably, the recovery chamber is provided with a first electromagnetic mesh, a second electromagnetic mesh, and an isolation mesh, all of which are rotatably connected to the inner wall of the recovery chamber, and are arranged sequentially from top to bottom.

[0010] Preferably, the processing unit can drive the oil spraying part in the oil spraying swing component to perform lateral extrusion by rotating the rotating rod, and at the same time, the rotation of the oil spraying part and the rotating rod in the same direction can drive the nozzle in the swing component to perform continuous reciprocating arc motion.

[0011] Preferably, the adsorption section in the second oil tank is connected to the processing box through a recovery port, wherein the recovery port is an inverted trapezoidal structure with a large inlet and a small outlet, and the outlet of the recovery port is connected to the inlet of the recovery chamber.

[0012] Preferably, the positions of the filter holes on the first electromagnetic mesh and the second electromagnetic mesh correspond to each other, the insulating mesh is composed of a rubber magnetically absorbent material, which blocks the magnetic attraction between the first electromagnetic mesh and the second electromagnetic mesh, and the insulating mesh is also provided with filter holes that match the positions of the filter holes on the first electromagnetic mesh and the second electromagnetic mesh.

[0013] The present invention has the following beneficial effects: 1. This device drives the worm gear cutter to rotate via a rotating rod in the machining section, which meshes with the worm gear to be machined, driving it and the machining base to rotate, thus achieving precise cutting of the worm gear teeth. At the same time, the nozzle of the oil spraying swinging component performs a back-and-forth arc swinging motion, which can evenly spray lubricating oil on the machining area, reducing friction and heat during the cutting process, avoiding machining errors caused by overheating or excessive friction of the worm gear teeth, thereby improving machining accuracy. The stable cutting environment also helps to improve machining efficiency.

[0014] 2. By setting up an adsorption section, the device performs multi-stage filtration and recovery of lubricating oil. The second oil tank is divided into a filtration chamber and a recovery chamber by a partition plate. The oil filter first performs preliminary filtration of the lubricating oil. The first and second electromagnetic meshes in the recovery chamber use electromagnets to adsorb debris in the lubricating oil. The isolation mesh blocks the magnetic interference between the two, ensuring the adsorption effect. The treated lubricating oil can be supplied to the spraying section again through relevant pipelines, reducing lubricating oil waste and lowering production costs. After the first and second electromagnetic meshes adsorb debris, the debris can be released by rotating to cut off the power and discharged through the slag discharge valve, preventing debris from accumulating in the device, reducing component wear, and extending the service life of the equipment.

[0015] 3. The first and second electromagnetic meshes in the adsorption section can accurately adsorb metal debris in the lubricating oil, and the filter holes of the two meshes are matched accordingly. Combined with the blocking effect of the isolation mesh, the debris can be efficiently intercepted. This multi-stage adsorption filtration method can significantly improve the purity of the lubricating oil and prevent lubricating oil containing debris from re-entering the processing area and causing secondary scratches or wear on the worm gear teeth. This further ensures the processing quality of the worm gear teeth and reduces product scrap due to debris contamination. Attached Figure Description

[0020] Reference Figures 1-4The machining section also includes a machining base 8 and a worm gear 9. The machining section drives the worm cutter 11 to rotate laterally through the rotating rod 10, thereby driving the worm gear 9 and the machining base 8 to rotate slowly vertically inside the machining box 4 through the meshing of the worm cutter 11 and the worm gear 9 to be machined.

The worm cutter 11 is fixedly sleeved on the rotating rod 10. The processing part drives the rotating rod 10 to rotate through the second motor 12, which in turn drives the worm cutter 11 to rotate. The worm cutter 11 rotates to cut the worm wheel 9 to be processed. The bottom of the processing box 4 is provided with a recovery port 7, which is connected to the interior of the processing box 4.

[0022] In this embodiment, the machining base 8 is vertically mounted on the bottom wall of the machining box 4 via bearings. The worm gear 9 to be machined is sleeved on the machining base 8 and meshes with the worm cutter 11. When the second motor 12 drives the rotating rod 10 to rotate, the worm cutter 11 rotates synchronously. Through the meshing action, the worm gear 9 and the machining base 8 are driven to rotate slowly vertically, realizing continuous cutting of the gear teeth, ensuring the accuracy of the cutting trajectory, and improving the machining precision.

The oil spraying part drives the first reciprocating screw 15 to rotate via the rotation of the rotating rod 10, through the synchronous pulley 16 and the synchronous belt 17, thereby driving the slider 19 to reciprocate along the guide rod 18. The slider 19 drives the piston 23 to reciprocate in the first oil tank 22 through the push arm 20 and the push rod 21, thereby squeezing the lubricating oil and then spraying it out from the oil outlet pipe 27.

The oil outlet pipe 27 is a flexible and foldable hose structure. The swinging part drives the tooth block 29 to reciprocate through the rotation of the second reciprocating screw 28. The tooth block 29 drives the first gear 30 to rotate, the first gear 30 drives the second gear 31 to rotate, and the second gear 31 drives the nozzle 32 to reciprocate in an arc swinging motion along the direction of the rotating rod 10.

[0029] In this embodiment, when the rotating rod 10 rotates, it drives the first reciprocating screw 15 to rotate through the synchronous wheel 16 and the synchronous belt 17. The slider 19 reciprocates along the guide rod 18, pushing the piston 23 to squeeze the lubricating oil, which is then sprayed out from the nozzle 32 through the oil outlet pipe 27 to uniformly supply oil to the processing area. When the second reciprocating screw 28 rotates, the tooth block 29 drives the gear set to drive the nozzle 32 to swing back and forth in an arc, expanding the oil supply range and ensuring that the lubricating oil evenly covers the processing surface. Example 3:

[0030] Reference Figures 7-9The adsorption section includes a partition plate 33, which divides the interior of the second oil tank 25 into a filtration chamber and a recovery chamber. The recovery port 7 is connected to the recovery chamber. An oil passage hole is provided on the partition plate 33, and an oil passage mesh 34 that matches it is fixedly installed in the oil passage hole.

[0031] The recovery chamber is equipped with a first electromagnetic mesh 36, a second electromagnetic mesh 37, and an isolation mesh 38. The first electromagnetic mesh 36, the second electromagnetic mesh 37, and the isolation mesh 38 are all rotatably connected to the inner wall of the recovery chamber, and the first electromagnetic mesh 36, the second electromagnetic mesh 37, and the isolation mesh 38 are arranged sequentially from top to bottom.

[0032] The positions of the filter holes on the first electromagnetic mesh 36 and the second electromagnetic mesh 37 correspond to each other. The insulating mesh 38 is made of rubber magnetically absorbent material, which blocks the magnetic attraction between the first electromagnetic mesh 36 and the second electromagnetic mesh 37.

The drive control end of the electric controller 40 is fixedly connected to the rotating shaft 35, and the energized end of the electric controller 40 is connected to the first electromagnetic mesh 36 and the second electromagnetic mesh 37 respectively. An arc-shaped baffle 41 is fixedly installed on one side of the isolation mesh 38. The arc-shaped blocking area of ​​the baffle 41 matches the inlet area of ​​the recovery chamber, and is used to temporarily block and prevent leakage of feed debris at the inlet of the recovery chamber when the electromagnetic mesh rotates.

[0034] In this embodiment, the partition 33 inside the second oil tank 25 divides it into a filtration chamber and a recovery chamber. The oil filter 34 on the partition 33 performs preliminary filtration of the returned lubricating oil. The recovery chamber is equipped with a first electromagnetic mesh 36, an isolation mesh 38, and a second electromagnetic mesh 37 from top to bottom. All three are connected to the inner wall through a rotating shaft 35, and the filter holes are positioned accordingly.

When the lubricating oil flows into the recovery chamber, the energized electromagnetic mesh attracts the metal debris. The processed lubricating oil flows into the filtration chamber for recycling. Periodically, by rotating the electromagnetic mesh and de-energizing it, the debris falls to the bottom under gravity and is discharged through the slag outlet valve, preventing debris from accumulating and wearing down parts.
