Description

Technical Field

[0001] This invention relates to the field of gear processing technology, specifically to a grinding device for precision gear processing. Background Technology

[0002] In actual gear manufacturing, grinding is an important processing method. Worm wheel grinding machines play a core role in precision machining in gear manufacturing. Worm wheels can be reshaped and ground when wear accuracy deviations occur. Worm wheel grinding is a grinding process based on the principle of staggered shaft meshing. High-precision tooth surface machining is achieved through the synchronous meshing motion of the worm-shaped grinding wheel and the gear workpiece. The worm wheel is an important component of worm wheel grinding equipment. Current precision gear grinding machines are not convenient for automatic control to perform reshaping and calibration of the worm wheel before its first use. Manually forgetting to perform reshaping and calibration before installation and use can easily lead to poor accuracy control. At the same time, it is not convenient to apply air pressure locally to the grinding wheel to prevent grinding powder from penetrating into the grinding wheel, which shortens the grinding cycle and affects grinding efficiency. It is also not convenient to automatically control to prevent the speed from being too high. Different sizes of worm wheels have different speed requirements, and excessive speed can easily cause the grinding wheel to break and other hidden dangers.

[0003] Therefore, we propose a grinding device for precision gear machining. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention employs a grinding wheel section to prevent operators from performing shaping and grinding work on the worm wheel grinding wheel before installing the grinding wheel section on the grinding wheel spindle of the worm wheel grinding machine. This eliminates accuracy deviations after the worm wheel is initially installed on the grinding wheel spindle, ensuring the accuracy of subsequent gear grinding and improving processing quality. The use of a collapsible positioning component in conjunction with a collapsible connecting component prevents operators from directly grinding the gears without removing the protrusions, which could cause jamming. This protects the worm wheel from jamming and breakage. Simultaneously, the collapsible positioning component also assists in collapsing protection when occasional deformation of the worm wheel or excessive friction between the worm wheel and gears causes jamming, achieving disconnection and preventing further damage.

[0016] The use of a local air supply component allows for air jetting of the worm grinding wheel. Utilizing the inherent void structure of the worm grinding wheel, positive pressure airflow is achieved, forming a directional chip removal channel. Grinding chips are discharged from the grinding wheel surface in real time, reducing the probability of pore blockage and preventing abrasive passivation caused by chip accumulation. At the same time, this structure ensures that air is only supplied to the front side of the worm grinding wheel in real time, unaffected by the rotation of the worm grinding wheel, i.e., the position where it contacts and grinds the gears, providing anti-blockage protection and more concentrated airflow.

[0017] Using an overspeed control device allows for automatic detection of the centrifugal force generated by rotation, preventing excessive centrifugal force from causing the worm wheel to break and affecting the grinding effect. The overspeed control device also enables automatic control, ensuring the protective effect and preventing unauthorized increases in grinding speed. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1 to 10 As shown: This invention provides a technical solution: a precision gear grinding device, comprising a grinding wheel section 1, a collapsible connector 2 mounted on the grinding wheel section 1, the grinding wheel section 1 being used to control the initial dressing and straightening during first use; a collapsible positioning component 3 mounted on the collapsible connector 2; the collapsible positioning component 3 being used to prevent damage to the grinding wheel section 1; an air inlet 4 mounted on the grinding wheel section 1; the air inlet 4 being used to control the air supply pressure; and a local air supply component 5 installed inside the grinding wheel section 1; the local air supply component 5 being used to adjust the grinding wheel section... 1. Air supply; two overspeed control components 6 are installed on the grinding wheel section 1; the overspeed control components 6 are used to prevent excessive centrifugal force due to overspeed; the grinding wheel section 1 includes: a worm grinding wheel 101 and a protruding strip 1011, the worm grinding wheel 101 is provided with threaded protrusions; the protruding strip 1011 is fixedly installed on the worm grinding wheel 101, and the protruding strip 1011 protrudes from the threaded protrusions on the worm grinding wheel 101; the protruding strip 1011 is used for shaping and grinding; the worm grinding wheel 101 is used for grinding and processing gears.

[0022] The grinding wheel section 1 further includes: a supporting inner cylinder 102 and a vent 1021. The supporting inner cylinder 102 has a double-layer hollow structure. The supporting inner cylinder 102 is fixedly sleeved inside the worm grinding wheel 101. The outer wall of the supporting inner cylinder 102 has a mesh structure. A ring of vents 1021 is opened at the end of the outer wall of the supporting inner cylinder 102. The vents 1021 are located outside the worm grinding wheel 101. The inner wall of the supporting inner cylinder 102 has two annular grooves. The grinding wheel section 1 also includes: a limiting groove 1022. Two limiting grooves 1022 are opened on the inner side of the supporting inner cylinder 102. The limiting grooves 1022 have an arc-shaped structure. The grinding wheel section 1 can be used to restrict the operator from installing the grinding wheel section 1 on the grinding wheel spindle of the worm grinding wheel grinding machine. Afterwards, the worm wheel 101 is first shaped and ground to eliminate the accuracy deviation after the worm wheel 101 is initially installed on the grinding wheel spindle, ensuring the accuracy of subsequent gear grinding and improving the processing quality. During the installation of the grinding wheel, eccentricity or shaft misalignment can easily occur, resulting in the loss of the grinding wheel's roundness. The worm wheel needs to maintain the theoretical meshing clearance with the workpiece gear. The shaping process simultaneously reproduces the designed helix angle and lead of the grinding wheel; otherwise, interference or excessive clearance will occur during actual grinding, leading to tooth surface burns or out-of-tolerance accuracy. The protruding strip 1011 protrudes from the worm wheel 101 and has threaded protrusions, which will prevent normal gear grinding and cause jamming. This restricts the workers from grinding and dressing the worm wheel 101 first to prevent forgetting to do so.

[0023] The collapsible connector 2 includes: a rotary drum 201, a manual switch 202, and an electromagnet 203. The rotary drum 201 is sleeved in the middle of the inner support cylinder 102. The manual switch 202 is fixedly installed on the side of the rotary drum 201. The electromagnet 203 is fixedly sleeved inside the rotary drum 201, and a battery is provided on the rotary drum 201 to power the electromagnet 203. The manual switch 202 is electrically connected to the electromagnet 203. The rotary drum 201 is used to connect to the grinding wheel spindle of the worm gear grinding machine. The collapsible positioning component 3 includes: a collapsible positioning pin 301, a retraction switch 302, and a pressure spring 303. Two collapsible positioning pins 301 are slidably inserted into the rotary drum 201. The two collapsible positioning posts 301 have arc-shaped hemispherical ends; the ends of the two collapsible positioning posts 301 are respectively inserted into the two limiting grooves 1022; the insertion depth of the collapsible positioning post 301 in the limiting groove 1022 is less than the radius of the hemispherical end of the collapsible positioning post 301; a pressure spring 303 is fixedly installed at the bottom of each of the two collapsible positioning posts 301, and the ends of the two pressure springs 303 are attached to the electromagnet 203; the electromagnet 203 is used to magnetically attract the collapsible positioning post 301; the retraction switch 302 is used to compress and adhere the electromagnet 203; the retraction switch 302 is electrically connected to the electromagnet 203. The use of the collapsible positioning part 3 in conjunction with the collapsible connecting part 2 can be used for prevention. This design prevents workers from directly grinding gears without removing the raised strip 1011, which could cause jamming. It protects the worm grinding wheel 101, preventing it from becoming stuck and breaking. The structure is more rational, ensuring the safety of the worm grinding wheel 101. It ensures that the raised strip 1011 must be removed before normal grinding. The structure is more rational, and the use of the collapsible positioning element 3 also provides auxiliary collapsible protection in case of occasional deformation of the worm grinding wheel 101 or excessive friction between the gears, causing jamming. This achieves disconnection and prevents further damage. If gears or worm grinding wheels are directly ground without removing the raised strip 1011... When wear, eccentric deformation, or excessive friction between gears causes jamming in wheel 101, the pressure exerted by the rotary drum 201 on the collapsible positioning post 301 increases. Utilizing the hemispherical arc structure at the end of the collapsible positioning post 301, when the pressure caused by jamming exceeds the limit, the collapsible positioning post 301 is squeezed inward by the limiting groove 1022, compressing the pressure spring 303. At this time, the end of the retraction switch 302 is also driven to squeeze and adhere to the electromagnet 203. The electromagnet 203 then conducts electromagnetic attraction to the collapsible positioning post 301, causing it to retract directly and no longer engage with the limiting groove 1022. The supporting inner cylinder 102 will then be in a free-spinning protection state.

[0024] The air receiving component 4 includes an air receiving ring 401 and an air receiving counterweight 402. The air receiving ring 401 is sleeved on the inner support cylinder 102. The air receiving ring 401 is located outside a ring of vent holes 1021. The inner side of the air receiving ring 401 has a groove structure. An air pump is connected to the side of the air receiving ring 401 through a hose. The air receiving counterweight 402 is fixedly installed at the bottom of the air receiving ring 401 by bolts. The air receiving ring 401 is used to supply air to the hollow area inside the inner support cylinder 102. The local air supply component 5 includes a centralized inner cylinder 501 and a drag-reducing roller. The concentrating inner cylinder 501 is fitted inside the supporting inner cylinder 102. Two rings of drag-reducing balls 5011 are embedded inside the concentrating inner cylinder 501. The two rings of drag-reducing balls 5011 roll and fit into grooves on the inner wall of the supporting inner cylinder 102. The concentrating inner cylinder 501 is fixedly mounted to the outside of the concentrating inner cylinder 502 by a bracket, and the outside of the concentrating inner cylinder 502 is attached to the inner side of the outer wall of the supporting inner cylinder 102. The concentrating inner cylinder 502 has rectangular slots. The rectangular slots on the concentrating inner cylinder 502 are used for... Air is supplied to the worm grinding wheel 101; drag-reducing balls 5011 are used for rolling drag reduction; the local air supply component 5 also includes: an air collecting counterweight 503, which is fixedly installed between the central inner cylinder 501 and the air collecting cylinder 502; the air collecting counterweight 503 is used to counterweight the central inner cylinder 501 and maintain the air supply position. The local air supply component 5 can be used to spray air onto the worm grinding wheel 101, utilizing the gap structure of the worm grinding wheel 101 itself to achieve positive pressure ventilation, and the airflow forms a directional chip removal channel for grinding. Debris is discharged from the grinding wheel surface in real time, reducing the probability of pore blockage and avoiding abrasive passivation caused by chip accumulation. At the same time, this structure can ensure that air is discharged and protected against blockage only on the front side of the worm grinding wheel 101, that is, the part that contacts the gear for grinding, without being affected by the rotation of the worm grinding wheel 101. The airflow is more concentrated, further extending the service life of the worm grinding wheel 101. The structure is more reasonable, reducing the rotational jamming rate of the worm grinding wheel 101 caused by the accumulation of grinding particles and impurities, reducing the frequency of dressing. The structure is more reasonable.

[0025] In Example 2, based on Example 1, the overspeed control component 6 includes: a rotary slide 601 and a centrifugal spring 6011. Two rotary slides 601 are threadedly connected to the rotary cylinder 201, and centrifugal springs 6011 are respectively sleeved inside the two rotary slides 601; the two rotary slides 601 are used to maintain rotational balance; the overspeed control component 6 also includes: a counterweight column 602 and a centrifugal switch 603. The counterweight column 602 is slidably sleeved inside the two rotary slides 601; the two centrifugal springs 6011 are respectively connected to the two... Between the counterweight column 602 and the rotary slide 601; centrifugal switches 603 are fixedly installed at the bottom of the two counterweight columns 602 respectively, and the ends of the two centrifugal switches 603 are pressed against the rotary slide 201 respectively; the centrifugal switches 603 are electrically connected to the electromagnet 203. The overspeed control component 6 can realize the use of the centrifugal force generated by rotation to automatically detect and prevent the centrifugal force from being too large, causing the worm wheel 101 to break and affecting the grinding effect. The overspeed control component 6 can realize automatic control, ensure the protection effect, and avoid illegally increasing the grinding speed.

[0026] The working principle of this embodiment is as follows: First, after the inner support cylinder 102 is inserted into and clamped onto the grinding wheel spindle of the worm gear grinding machine, the protruding strip 1011 protrudes from the worm gear grinding wheel 101 and has a threaded protrusion, which prevents normal gear grinding and causes jamming. This restricts the operator from grinding and dressing the worm gear grinding wheel 101 first. The worm gear grinding machine uses its own shaping and grinding structure to grind and shape the worm gear grinding wheel 101, removing the protruding strip 1011 before proceeding with the subsequent gear grinding work. If the protruding strip 1011 is not removed before grinding the gears, or if the worm gear grinding wheel 101 is worn, eccentrically deformed, or the friction between the gears exceeds the limit, the operation will be compromised. When the discrepancy causes jamming, the pressure exerted by the rotary drum 201 on the collapsible positioning post 301 increases. Utilizing the hemispherical arc structure at the end of the collapsible positioning post 301, when the pressure caused by the jamming exceeds the limit, the collapsible positioning post 301 is squeezed inward by the limiting groove 1022, compressing the pressure spring 303. At this time, the end of the retraction switch 302 is also driven to press against the electromagnet 203. The electromagnet 203 then conducts electromagnetic attraction to the collapsible positioning post 301, causing it to retract directly and no longer engage with the limiting groove 1022. The supporting inner cylinder 102 will then be in an idling state, preventing the worm wheel 101 from breaking due to jamming. The magnetic attraction needs to be released subsequently. When the collapsible positioning post 301 is in operation, the manual switch 202 can be pressed manually to de-energize the electromagnet 203. Aligning the collapsible positioning post 301 with the limit groove 1022 will then complete the reset process. An air pump is connected to the side of the air receiving ring 401 via a flexible hose. This, along with the counterweight 402, ensures stable air supply to the inner support cylinder 102. When the inner support cylinder 102 rotates, driving the worm gear grinding wheel 101 to grind the gears, the counterweight 503 concentrates the air, allowing the inner cylinder 501 to remain relatively stationary inside the inner support cylinder 102 without affecting its normal rotation. This maintains the rectangular slot on the air collecting cylinder 502. Ventilation is always provided at the front, while the remaining areas are blocked by the air collection duct 502, ensuring that the air pressure is concentrated at the front for discharge and providing anti-blocking positive pressure supply. When the rotation speed of the rotary drum 201 is too fast, the centrifugal force will increase, causing the counterweight column 602 to shift outward, which will compress the centrifugal spring 6011. At this time, the centrifugal switch 603 will no longer be pressed, and the centrifugal switch 603 will control the electromagnet 203 to be activated again to attract the collapsible positioning column 301. The collapsible positioning column 301 will retract directly and will no longer be inserted into the limit groove 1022. Similarly, at this time, the worm gear grinding wheel 101 can idle and reduce speed for protection, avoiding continuous high-speed rotation and preventing further damage and increased fragmentation.
