Description

Technical Field

[0001] The utility model relates to the technical field of gear grinding, in particular to an efficient gear grinding device for processing special-shaped gears. Background Technique

[0002] A gear refers to a mechanical element with teeth on the rim that continuously mesh to transmit motion and power. When processing special-shaped gears, an efficient gear grinding device for processing special-shaped gears is required.

[0003] For example, a gear grinding tooling for processing special-shaped gears with the authorization announcement number of "CN216325619U". Through the cooperation between a disc, a first slider, a second slider, a slide bar, a first support rod, a third slider, a slideway and a spring, the slide bar drives the second slider to move, the second slider drives the first support rod to move, the first support rod drives the third slider to slide. Under the connection of the second slider and the first slider, the first slider drives the third slider to move through the second slider and the first support rod. The third slider drives the air grinding rod to move through an electric telescopic rod and a grinding frame. However, when the device drives the double-headed stud to rotate by turning the handle, and the double-headed stud drives the first clamping plate and the second clamping plate to clamp and fix the gear, when being impacted by an external force, the handwheel deflects, resulting in the loosening of the fixation of the first clamping plate and the second clamping plate to the gear, leading to unstable fixation of the gear and reducing the processing quality of the device. When the device grinds the gear with an air grinding rod, a large amount of iron filings will fly, and the flying iron filings are likely to cause injury to the operator, reducing the working safety of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when driving the double-headed stud to rotate by turning the handle, and the double-headed stud drives the first clamping plate and the second clamping plate to clamp and fix the gear, when being impacted by an external force, the handwheel deflects, resulting in the loosening of the fixation of the first clamping plate and the second clamping plate to the gear, leading to unstable fixation of the gear and reducing the processing quality of the device, and when grinding the gear with an air grinding rod, a large amount of iron filings will fly, and the flying iron filings are likely to cause injury to the operator, reducing the working safety of the device. Thus, an efficient gear grinding device for processing special-shaped gears is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design an efficient gear grinding device for processing special-shaped gears, including a first housing and a second housing. The left end of the first housing is fixedly connected to the second housing. A protection device is arranged inside the first housing. A fixing device is arranged inside the second housing. The right end of the first housing is fixedly connected to a third housing. The third housing is fixedly connected to a third motor through a bracket. A threaded rod is fixedly connected to the output shaft of the third motor.

[0007] Preferably, the fixing device includes a worm and a worm wheel. The two ends of the worm are rotatably connected to the second housing through bearings. The right end of the worm is inserted into a rocker. The outer wall of the worm is engaged with the worm wheel. A double-headed stud is fixedly connected to the inner wall of the worm wheel. The outer wall of the double-headed stud is threadedly connected to a clamping arm. The clamping arm is movably connected to a clamping plate through a bearing. The upper clamping arm is fixedly connected to a second motor through a bracket. A upper clamping plate is fixedly connected to the output shaft of the second motor.

[0008] Preferably, the two ends of the double-headed stud are rotatably connected to the second housing through bearings. The outer wall of the clamping arm is slidably connected to the second housing.

[0009] Preferably, the two ends of the threaded rod are rotatably connected to the third housing through bearings. The outer wall of the threaded rod is threadedly connected to a threaded block. The outer wall of the threaded block is slidably connected to the third housing. A hydraulic cylinder is fixedly connected to the left end of the threaded block. A pneumatic grinding rod is fixedly connected to the telescopic end of the hydraulic cylinder.

[0010] Preferably, the protection device includes a first motor and a turntable. The first motor is fixedly connected to the first housing through a bracket. The output shaft of the first motor is rotatably connected to the first housing through a bearing. A turntable is fixedly connected to the output shaft of the first motor. A convex block is fixedly connected to the outer wall of the turntable. The outer wall of the convex block is slidably connected to a slider. A baffle is fixedly connected to the upper end of the slider. A fixed rod is fixedly connected to the inner wall of the first housing.

[0011] Preferably, the inner wall of the slider is slidably connected to the fixed rod. The outer walls of the slider and the baffle are both slidably connected to the first housing.

[0012] For the efficient gear grinding equipment for processing special-shaped gears proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the fixing device and the second housing, the operator places the special-shaped gear on the surface of the lower clamping plate, inserts the rocker into the groove inside the worm, rotates the rocker to drive the worm to rotate, the worm drives the worm wheel and the double-headed stud to rotate synchronously. While the double-headed stud rotates, it drives the clamping arms and the clamping plates on both sides to move inward. After the clamping plates on both sides contact the special-shaped gear, they are tightened and fixed. After fixing, the rocker is pulled out. By pulling out the rocker, it is avoided that when the rocker drives the worm to deflect when being externally collided during subsequent processing, resulting in the loosening of the clamping plate, making the clamping of the special-shaped gear by the clamping plate more stable and improving the processing quality.

[0013] Through the cooperation of the protection device and the first outer shell, the output shaft of the first motor is started to rotate, driving the turntable and the convex block to rotate. While the convex block slides inside the slider, it drives the slider to move upward, and the slider drives the baffle to move upward synchronously. When the baffle moves to the highest point, the rotation of the output shaft of the first motor drives the baffle to move to the highest point. Since the middle of the baffle is transparent, the processing state of the special-shaped gear can be observed during the subsequent grinding of the special-shaped gear. At the same time, the flying iron chips generated by grinding will bounce on the surface of the baffle and will not cause damage to the operator, improving the safety of the work.

The hydraulic cylinder 9 can meet the working requirements according to actual needs. The telescopic end of the hydraulic cylinder 9 is fixedly connected to a pneumatic grinding rod 10. The pneumatic grinding rod 10 has been disclosed in the authorization announcement number "CN216325619U", and will not be elaborated here. The inner wall of the slider 304 is slidably connected to the fixed rod 306. The outer walls of the slider 304 and the baffle 305 are both slidably connected to the first housing 1. The baffle 305 is a transparent plate, and the gear grinding state can be observed.

[0024] Refer to the appendix Figures 1-4 : The fixing device 2 includes a worm 201 and a worm gear 202. The end of the worm 201 is processed with a groove. Both ends of the worm 201 are rotatably connected to the second housing 4 through bearings. The right end of the worm 201 is inserted into the rocker 205. The end of the insertion part of the rocker 205 is hexagonal and fits the groove at the end of the worm 201. The outer wall of the worm 201 is meshed with the worm gear 202. Due to the characteristics of the worm and worm gear, the rotation of the worm 201 drives the rotation of the worm gear 202. The inner wall of the worm gear 202 is fixedly connected to a double-headed stud 203. The rotation of the worm gear 202 drives the synchronous rotation of the double-headed stud 203. The outer wall of the double-headed stud 203 is threadedly connected to the clamping arm 204. The rotation of the double-headed stud 203 drives the two clamping arms 204 to move in opposite directions. The clamping arm 204 is movably connected to the clamping plate 206 through a bearing. The upper clamping arm 204 is fixedly connected to a second motor 207 through a bracket. The output shaft of the second motor 207 is fixedly connected to the upper clamping plate 206. The second motor 207 can meet the working requirements according to actual needs. When the special-shaped gear is clamped and fixed by the two clamping plates 206, the rotation of the output shaft of the second motor 207 drives the rotation of the upper clamping plate 206, thereby driving the rotation of the special-shaped gear.

An outer wall of the turntable 302 is fixedly connected to a convex block 303. The rotation of the turntable 302 drives the convex block 303 to rotate synchronously. The outer wall of the convex block 303 is slidably connected to a slider 304. While the convex block 303 moves inside the slider 304, it drives the slider 304 to move vertically. An upper end of the slider 304 is fixedly connected to a baffle 305. While the slider 304 moves, it drives the baffle 305 to move synchronously. A fixed rod 306 is fixedly connected to an inner wall of the first housing 1.

[0026] Working principle:

[0027] Fixing process of the special-shaped gear:

[0028] The operator places the special-shaped gear on the surface of the lower clamping plate 206, inserts the rocker 205 into the groove inside the worm 201, rotates the rocker 205 to drive the worm 201 to rotate, the worm 201 drives the worm wheel 202 and the double-headed stud 203 to rotate synchronously. While the double-headed stud 203 rotates, it drives the clamping arms 204 and the clamping plates 206 on both sides to move inward. After the clamping plates 206 on both sides come into contact with the special-shaped gear, they are tightened and fixed. After fixing, the rocker 205 is pulled out to prevent the worm 201 from deflecting driven by the rocker 205 when being collided by an external force during subsequent processing, resulting in the loosening of the clamping plate 206, thus completing the fixing process of the special-shaped gear. When the grinding process of the special-shaped gear is completed, controlling the reverse operation of the above process can take out the processed special-shaped gear.

[0029] Protective process for grinding the special-shaped gear:

[0030] Connect the external power supply of the first motor 301, start the rotation of the output shaft of the first motor 301 to drive the turntable 302 and the convex block 303 to rotate. While the convex block 303 slides inside the slider 304, it drives the slider 304 to move upward. The slider 304 drives the baffle 305 to move upward synchronously. When the baffle 305 moves to the highest point, stop the rotation of the output shaft of the first motor 301, fixing the position of the baffle 305. Since the middle of the baffle 305 is transparent, the processing state of the special-shaped gear can be observed during the subsequent grinding process of the special-shaped gear. At the same time, the flying iron filings generated by grinding will bounce on the surface of the baffle 305 and will not cause damage to the operator, thus completing the protective process for grinding the special-shaped gear.

[0031] Grinding process for the special-shaped gear:

[0032] Connect the external air source of the air grinding rod 10, start the air grinding rod 10 to rotate. The working principle of the air grinding rod 10 is the same as that in the authorized announcement number "CN216325619U". Start the telescopic end of the hydraulic cylinder 9 to extend and drive the air grinding rod 10 to move closer to the special-shaped gear. Connect the external power supply of the third motor 6, start the output shaft of the third motor 6 to rotate and drive the threaded rod 7 to rotate. The rotation of the threaded rod 7 drives the threaded block 8 and the air grinding rod 10 to move downward. After the air grinding rod 10 moves downward and contacts the special-shaped gear, gear grinding processing is carried out on the special-shaped gear. By controlling the forward and reverse rotation of the output shaft of the third motor 6, the air grinding rod 10 moves up and down to perform gear grinding processing on the special-shaped gear. When the processing of one tooth is completed, connect the external power supply of the second motor 207, start the output shaft of the second motor 207 to rotate and drive the clamping plate 206 and the special-shaped gear to rotate. According to the working requirements, control the telescopic end of the hydraulic cylinder 9 to move, adjust the processing position of the air grinding rod 10, and then carry out gear grinding processing on the next tooth to adapt to the change in the outer wall shape of the special-shaped gear, thus completing the gear grinding process of the special-shaped gear.
