DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1-6As shown in the figure, the utility model provides a technical solution: a device for fixed grinding operation of superalloy bars, including a base 1. One end of the upper surface of the base 1 is fixedly connected with a clamping table 2. A set of clamps 3 are movably connected to the upper surface of the clamping table 2. The center of the inner wall of the clamp 3 is movably connected with a bar of alloy to be processed 4. One side wall of the clamping table 2 is fixedly connected with a driving motor 5. The output shaft of the driving motor 5 is movably connected with the bar of alloy to be processed 4. The center position of the upper surface of the base 1 is fixedly connected with a waste chip hopper 6. The other end of the upper surface of the base 1 is fixedly connected with a supporting table 7. The center of one side of the supporting table 7 is movably connected with an adjusting handwheel 8. The bar of alloy to be processed 4 is movably connected between the clamping table 2 and the supporting table 7. A grinding tool holder 9 is fixedly connected between the side wall of the clamping table 2 and the side wall of the supporting table 7. Grinding wheels 10 are respectively movably connected to both sides of the top of the grinding tool holder 9.

[0025] Using the overall structure of the device, when grinding a superalloy bar, first hoist the bar of alloy to be processed 4 between the clamping table 2 and the supporting table 7 through the equipment, fix one end of it through the clamp 3, and place the other end above the supporting table 7. Then adjust the supporting distance through the adjusting handwheel 8 until it is supported and fixed. Subsequently, start the driving motor 5 through the control system. Under the action of the driving motor 5, the bar of alloy to be processed 4 starts to rotate at a high speed inside the clamp 3. During the rotation process, control the grinding wheel 10 to move laterally along the grinding tool holder 9 through the control system. The bar of alloy to be processed 4 rotating at a high speed is ground under the action of the grinding wheel 10.

[0026] As Figures 1-6 As shown in the figure, a clamping slide rail 201 is fixedly connected to the upper surface of the clamping table 2. One side of the clamping table 2 is fixedly connected with a side plate 202. The center of the top of the side plate 202 is rotatably connected with a first center punch 203 through a bearing. One end of the first center punch 203 has a certain taper. The first center punch 203 is fixedly connected to the output shaft of the driving motor 5. The driving motor 5 is fixedly connected to the outer wall of the side plate 202 through a flange. A fixing groove 301 is opened inside one end of the clamp 3. The fixing groove 301 is semi-circular. A number of rollers 302 are rotatably connected to the fixing groove 301 through a bearing. A set of clamps 3 are symmetrically and fittingly installed. The outer wall of the roller 302 covers the outer wall of one end of the bar of alloy to be processed 4. A clamping chute 303 is opened on the lower surface of the clamp 3. The clamping chute 303 is slidably connected to the center of the outer wall of the clamping slide rail 201.

[0027] When grinding a superalloy bar, slide the clamp 3 on the clamping slide rail 201. When a pair of clamps 3 are clamped and fixed, the rollers 302 inside the clamp 3 cover the outer wall of the bar of alloy to be processed 4. Under the dual action of the clamp 3 and the first center punch 203, the radial and axial directions of the bar of alloy to be processed 4 are constrained and fixed.

[0028] As Figures 1-6As shown, a holding slide rail 701 is fixedly connected to the top end of the holding table 7. A thimble holder 702 is slidably connected to the upper surface of the holding slide rail 701. One end of the thimble holder 702 is rotatably connected to a second thimble 703 through a bearing. A rack 704 is fixedly connected to the bottom end of the thimble holder 702. A groove is formed in the center of the inner part of the top end of the holding table 7, and a through hole is arranged in the groove perpendicular to the side where the adjusting handwheel 8 is located. The top end of the adjusting handwheel 8 is rotatably connected to the through hole inside the holding table 7 through a bearing. The adjusting handwheel 8 is coaxially fixedly connected with an adjusting gear 801, and the adjusting gear 801 meshes with the outer wall of the rack 704.

[0029] When installing and fixing the alloy bar 4 to be processed, by rotating the adjusting handwheel 8, the adjusting gear 801 is driven to rotate. Under the action of the adjusting gear 801 with which it meshes, the rack 704 causes the thimble holder 702 to start sliding horizontally along the holding slide rail 701, so that the second thimble 703 touches the end face of the alloy bar 4 to be processed until it is fixed. When it is necessary to loosen after the processing is completed, just reverse the adjusting handwheel 8.

[0030] As Figures 1-6 shown, guide slide rails 901 are respectively fixedly connected to both sides of the grinding tool holder 9. A threaded lead screw 902 is fixedly connected above the guide slide rails 901. A grinding wheel 10 is movably connected to the outer walls of the guide slide rails 901 and the threaded lead screw 902. A guide chute 101 is formed at the bottom end of the grinding wheel 10, and the guide chute 101 is slidably connected to the outer wall of the guide slide rail 901. A threaded through hole 102 is formed inside the bottom end of the grinding wheel 10, and the threaded through hole 102 covers the outer wall of the threaded lead screw 902. The top end of the grinding wheel 10 is fixedly connected to a large grinding wheel 103 and a small grinding wheel 104 through bearings respectively, and the large grinding wheel 103 and the small grinding wheel 104 are respectively movably connected to the outer wall of the alloy bar 4 to be processed.

[0031] After the alloy bar to be processed is installed, the control system is used to start the driving motor 5 to rotate. Then, the large grinding wheel 103 and the small grinding wheel 104 inside the grinding wheel 10 are respectively attached to the outer wall of the alloy bar 4 to be processed, and the alloy bar 4 to be processed under high-speed rotation is ground. The control system is used to control the grinding wheel 10 to feed horizontally along the guide slide rails 901 and the threaded lead screw 902. The good degree of fit and the accurate horizontal feed ensure the stability of the alloy bar 4 to be processed and the quality of the grinding process.

[0032] Working principle: By utilizing the overall structure of the device, when grinding a superalloy bar, first lift the alloy bar 4 to be processed to the space between the clamping table 2 and the supporting table 7 through the equipment. Fix one end of it with the fixture 3, and place the other end above the supporting table 7. Then adjust the supporting distance by turning the adjusting handwheel 8 until it is supported and fixed. Subsequently, start the driving motor 5 through the control system. Under the action of the driving motor 5, the alloy bar 4 to be processed starts to rotate at high speed inside the fixture 3. During the rotation process, control the grinding wheel 10 to move laterally along the grinding tool rest 9 through the control system. The alloy bar 4 to be processed rotating at high speed is ground under the action of the grinding wheel 10. When grinding a superalloy bar, slide the fixture 3 on the clamping slide rail 201. After a pair of fixtures 3 clamp and fix, the rollers 302 inside the fixture 3 cover the outer wall of the alloy bar 4 to be processed. Under the dual action of the fixture 3 and the first thimble 203, the radial and axial directions of the alloy bar 4 to be processed are constrained and fixed. When installing and fixing the alloy bar 4 to be processed, turn the adjusting handwheel 8, drive the adjusting gear 801 to rotate. The rack 704 meshing with it moves laterally along the supporting slide rail 701 under the action of the adjusting gear 801, so that the second thimble 703 touches the end face of the alloy bar 4 to be processed until it is fixed. When it is necessary to loosen after the processing is completed, just reverse the adjusting handwheel 8. After the alloy bar to be processed is installed, start the driving motor 5 to rotate through the control system. Then the large grinding wheel 103 and the small grinding wheel 104 inside the grinding wheel 10 are respectively attached to the outer wall of the alloy bar 4 to be processed, and start to grind the alloy bar 4 to be processed rotating at high speed. Control the grinding wheel 10 to move laterally along the guiding slide rail 901 and the threaded lead screw 902 through the control system. The good fitting degree and the accurate lateral feed ensure the stability of the alloy bar 4 to be processed and the quality of the grinding process.
