During the production process, it is necessary to drill holes in the horizontal end face and vertical end face of the angle grinder head shell, and tap the blind holes on both sides.

[0003] Chinese Patent with Publication No. CN109719509B discloses an angle grinder head shell drilling and tapping device, including a frame. A workbench is arranged on the frame, and an electric linear slide rail is arranged on the workbench. A fixture for fixing the workpiece is arranged on the electric slide rail. A horizontal drilling power head, a vertical drilling power head, and a tapping power head are arranged on the workbench. The horizontal drilling power head, the vertical drilling power head, and the tapping power head are respectively adjustably installed on the workbench through adjusting devices.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. Start the stepping motor to drive the disc to rotate forward. First, drive the positioning rod and the positioning block to move and contact the front and rear sides of the head shell. The cooperation of the positioning rod and the positioning block can first complete the deviation correction and positioning between the head shell and the tapping machine, so that the head shell and the tapping machine are in a vertical state to prevent deviation in blind hole tapping caused by the head shell being skewed. Subsequently, the left and right sides of the head shell can be positioned through the arc-shaped plate to complete the final deviation correction and positioning. Then, the top of the head shell is limited by the clamping block, and then drilling and tapping of the head shell can be started. In this way, only after placing the head shell, the deviation correction and positioning can be completed through the cooperation of the positioning block, the positioning rod, and the arc-shaped clamping plate with three different shapes to complete precise drilling and tapping. Moreover, head shells of different sizes can be fixed after deviation correction and positioning for precise drilling and tapping, thereby improving the adaptability.

[0018] 2. Under the action of the buffer airbag, whenever the arc-shaped clamping plate moves, the arc-shaped clamping plate drives the buffer airbag to move and contact the head shell. After the arc-shaped clamping plate completes deviation correction and positioning of the head shell through the buffer airbag and clamps it, the buffer airbag buffers and protects the head shell, preventing the head shell from being worn due to the hard contact and clamping between the arc-shaped clamping plate and the head shell, thereby ensuring the complete quality of the head shell.

Subsequently, the head shells are drilled and tapped. The blocking component is installed on the circular shell 10. The blocking component can close the sliding part between the movable frame 11 and the circular shell 10 to prevent debris from falling into the circular shell 10.

[0033] Please refer to Figure 3As shown in the figure, the pressing component includes clamping blocks 9 and a servo motor 91. The middle parts of the tops of the front and rear sliding frames 7 are rotatably connected to the clamping blocks 9. When the clamping blocks 9 swing downward to contact the head shell, the clamping blocks 9 can clamp and fix the head shell. The servo motor 91 is installed on the right side of the tops of the front and rear sliding frames 7, and the end of the output shaft of the servo motor 91 is fixedly connected to the shaft part of the clamping block 9.

[0034] Please refer to Fig. 6. The laser rangefinder includes an elastic telescopic rod II 161, a movable plate 162, a laser emitter 163, a receiver 164, and a rectangular mounting plate 165. Rectangular mounting plates 165 are fixedly connected to the upper parts of the left and right movable frames 11. Elastic telescopic rods II 161 are fixedly connected to the upper parts of the left and right rectangular mounting plates 165 and the tops of the front and rear movable frames 11. The ends of the front and rear elastic telescopic rods II 161 are fixedly connected to the movable plates 162. The front and rear movable plates 162 respectively slide through the middle parts of the front and rear sliding frames 7. A laser emitter 163 is installed on the upper part of the front movable plate 162 and the end of the left elastic telescopic rod II 161. A receiver 164 is installed on the upper part of the rear movable plate 162 and the end of the right elastic telescopic rod II 161. The receiver 164 corresponds to the laser emitter 163.

[0035] Please refer to Figure 4 As shown in the figure, the blocking component includes a rectangular plate 17 and an elastic cloth 171. Four rectangular plates 17 are fixedly connected to the outer top of the circular shell 10 at equal intervals along the circumference. The four movable frames 11 respectively pass through the four rectangular plates 17. The elastic cloth 171 is fixedly connected to the inner side of the rectangular plate 17. When the movable frame 11 moves, the elastic cloth 171 can seal the sliding part between the movable frame 11 and the circular shell 10.

[0036] Please refer to Figure 4 、 Figure 7 and Figure 8 As shown in the figure, the driving component includes a disc 18 and a stepping motor 182. The stepping motor 182 is installed on the front side of the top of the base 2. The end of the output shaft of the stepping motor 182 is fixedly connected to the disc 18. The disc 18 is located inside the circular shell 10. Four inclined holes 181 are evenly spaced along the circumference on the disc 18. The inner sides of the four inclined holes 181 are respectively slidably connected to the four movable frames 11. When the inclined holes 181 rotate, the inclined holes 181 can drive the movable frames 11 to move.

[0037] First, start the electric lead screw 8 to rotate. The rotation of the electric lead screw 8 drives the sliding frames 7 on the front and rear sides to move in and out. Due to the action of the elastic telescopic rod II 161, the movable plate 162 will not affect the movement of the sliding frame 7. When the sliding frame 7 moves in and out to a position suitable for placing the head shell, turn off the electric lead screw 8, and the sliding frame 7 stops moving. Then, place the head shell between the sliding frames 7 on the front and rear sides, and make the head shell correspond to the clamping blocks 9. Then, start the stepping motor 182 to drive the disc 18 to rotate forward. The forward rotation of the disc 18 drives the inclined holes 181 to rotate forward. The forward rotation of the inclined holes 181 drives the four movable frames 11 to move in the direction of approaching each other. The movable frames 11 on the front and rear sides drive the movable plates 162 on the front and rear sides to move in the direction of approaching each other through the elastic telescopic rod II 161. The movable plate 162 drives the front laser emitter 163 to move backward and the rear receiver 164 to move forward. When the movable plate 162 moves and contacts the front and rear sides of the upper part of the head shell, the movable plate 162 stops moving. The movable frames 11 on the front and rear sides continue to move and compress the elastic telescopic rod II 161. And the movable frames 11 on the left and right sides drive the elastic telescopic rods II 161 on the left and right sides to move in the direction of approaching each other through the loop-shaped mounting plate 165. The elastic telescopic rods II 161 on the left and right sides drive the left laser emitter 163 to move to the right and the right receiver 164 to move to the left, so that the left laser emitter 163 and the right receiver 164 move and contact the left and right sides of the upper part of the head shell and stop moving. The loop-shaped mounting plate 165 continues to move and compress the elastic telescopic rods II 161 on the left and right sides. At the same time, the movable frame 11 drives the elastic cloth 171 to move. The movable frame 11 also drives the arc-shaped clamping plates 13, the positioning rods 15, and the positioning blocks 14 to move in the direction of approaching each other through the elastic telescopic rod I 12. The positioning rod 15 first contacts the front side of the head shell. The positioning rod 15 first positions the head shell, and the head shell limits the positioning rod 15. The front movable frame 11 continues to move backward and compresses the front elastic telescopic rod I 12. Subsequently, the remaining three elastic telescopic rods I 12 continue to drive the positioning block 14 and the arc-shaped clamping plate 13 to move in the direction of approaching each other. The positioning block 14 contacts the head shell. The positioning block 14 and the positioning rod 15 cooperate to first correct and position the head shell, so that the head shell is perpendicular to the tapping machine 6 to prevent the head shell from being skewed and causing deviation in tapping, thereby ensuring the accuracy of tapping. Subsequently, the arc-shaped clamping plates 13 on the left and right sides contact the head shell, and the arc-shaped clamping plates 13 clamp and fix the head shell to complete the final correction and positioning. Turn off the stepping motor 182, and the disc 18 stops driving the inclined holes 181 to rotate forward. The inclined holes 181 stop driving the movable frame 11 to move. The movable frame 11 stops driving the elastic cloth 171 to move. Due to the action of the elastic telescopic rod I 12, the positioning block 14, the positioning rod 15, and the arc-shaped clamping plate 13 can contact the head shell more tightly for clamping and fixing. And through the three different shapes of the positioning block 14, the positioning rod 15, and the arc-shaped clamping plate 13, it can adapt to the head shell to avoid correction and positioning to complete precise drilling and tapping. Subsequently, start the laser emitter 163, and the laser emitter 163 emits a laser beam and irradiates it on the receiver 164.The receiver 164 cooperates with the laser transmitter 163 to measure the length and width of the upper part of the head shell. The measured data is transmitted to the terminal to calculate the hole spacing of the head shell that needs to be drilled, so as to set the moving trajectory of the vertical drilling machine 4 and the horizontal drilling machine 5. In this way, the hole spacing can be positioned during the deviation correction and positioning process, so there is no need to manually set the parameters of the vertical drilling machine 4 and the horizontal drilling machine 5, and the operation is more convenient. Then, the servo motor 91 is started to drive the front and rear clamping blocks 9 to swing downward, and the front and rear clamping blocks 9 swing downward to contact the head shell. The clamping blocks 9 limit the top of the head shell, and the clamping blocks 9 press the head shell after deviation correction and positioning. Fix, turn off the servo motor 91, then start the vertical drilling machine 4 to move and perform vertical drilling operations on the head shell. When the vertical drilling of the vertical drilling machine 4 is completed, start the vertical drilling machine 4 to move upward and reset, and then start the horizontal drilling machine 5 and the tapping machine 6 to move, so that the horizontal drilling and tapping machines 6 perform horizontal drilling and tapping operations on the head shell. Since the head shell and the tapping machine 6 are in a vertical state, the tapping machine 6 can also accurately tap the blind hole of the head shell. The debris generated by the drilling falls onto the round shell 10, and the elastic cloth 171 can block the fallen debris to prevent the debris from falling into the round shell 10 and causing the oblique hole 181 to be blocked. , thereby ensuring the normal use of the inclined hole 181. When the horizontal drilling and tapping are completed, the horizontal drilling machine 5 and the tapping machine 6 are started to move and reset, and then the servo motor 91 is started to rotate in the opposite direction to drive the front and rear clamping blocks 9 to swing upward and reset. The clamping blocks 9 swing and reset and break contact with the head shell, and then the stepper motor 182 is started to drive the disc 18 to reverse, and the disc 18 reverses to drive the inclined hole 181 to reverse, and the inclined hole 181 reverses to drive the four movable frames 11 to move and reset in the direction away from each other, and the movable frame 11 drives the elastic cloth 171. The movable frame 11 drives the positioning rod 15, the positioning block 14 and the arc clamping plate 13 to move away from each other through the elastic telescopic rod Ⅰ12. Move and reset in the direction away from the head shell, and the positioning rod 15, the positioning block 14 and the arc splint 13 are reset and disengaged from the head shell. Then, the head shell after drilling and tapping is removed from the sliding frame 7, and the next head shell is placed between the front and rear sliding frames 7. This is repeated to continuously drill and tap the head shell. When the drilling and tapping of the head shell are all completed, the vertical drilling machine 4, the horizontal drilling machine 5 and the tapping machine 6 are turned off. In this way, it is only necessary to place the head shell, and through the positioning block 14, the positioning rod 15 and the arc splint 13, the head shells of different sizes can be corrected and positioned, and then fixed to complete accurate drilling and tapping, thereby improving adaptability.

[0038] See also Figure 9As shown in the figure, the angle grinder casting head shell drilling and tapping integrated device further includes a buffer assembly installed between the base 2 and the arc-shaped clamping plate 13. The buffer assembly includes a buffer airbag 19, a hose 191 and a gas supply assembly. Buffer airbags 19 are fixedly connected to the mutually approaching sides of the left and right arc-shaped clamping plates 13. When the buffer airbag 19 expands, the buffer airbag 19 can buffer and protect the head shell. Hoses 191 are connected to the middle parts of the left and right buffer airbags 19. The tail ends of the hoses 191 penetrate through the arc-shaped clamping plates 13. A gas supply assembly is arranged between the base 2 and the movable frame 11. When the gas supply assembly operates, the gas supply assembly can discharge air into the hoses 191 to make the buffer airbags 19 expand; the gas supply assembly includes a support seat 192, a cylinder block 193 and a piston rod 194. Support seats 192 are symmetrically and fixedly connected to the front side of the top of the base 2. The upper parts of the left and right support seats 192 are fixedly penetrated with cylinder blocks 193. Piston rods 194 are slidably connected to the inner sides of the left and right cylinder blocks 193. The end parts of the left and right piston rods 194 are respectively fixedly connected to the middle parts of the left and right movable frames 11. The mutually approaching positions of the left and right cylinder blocks 193 are respectively connected to the tail ends of the left and right hoses 191.

[0039] When the stepping motor 182 starts to drive the disk 18 to rotate forward, the disk 18 drives the inclined hole 181 to rotate forward, and the inclined hole 181 drives the four movable frames 11 to move in the direction of approaching each other. The movement of the left and right movable frames 11 drives the left and right piston rods 194 to move in the direction of approaching each other. The left and right piston rods 194 moving in the direction of approaching each other push the air in the cylinder block 193 into the hose 191, and the air in the hose 191 is discharged into the buffer airbag 19. As the air is discharged, the buffer airbag 19 continuously expands. At the same time, the left and right arc-shaped clamping plates 13 move in the direction of approaching each other, and the arc-shaped clamping plates 13 drive the left and right buffer airbags 19 to move in the direction of approaching each other. The buffer airbag 19 moves into contact with the head shell, and the arc-shaped clamping plate 13 corrects and positions the head shell through the buffer airbag 19, and clamps and fixes the head shell through the buffer airbag 19. The buffer airbag 19 protects the head shell, and then subsequent operations can be carried out to drill and tap the head shell. After the head shell is drilled and tapped, the stepping motor 182 starts to drive the disk 18 to rotate reversely. The reverse rotation of the disk 18 drives the four movable frames 11 to move in the direction of moving away from each other and reset through the inclined hole 181. The left and right movable frames 11 drive the left and right arc-shaped clamping plates 13 to move in the direction of moving away from each other through the elastic telescopic rod I 12. The arc-shaped clamping plates 13 drive the left and right buffer airbags 19 to move in the direction of moving away from each other and reset. The buffer airbag 19 is separated from the head shell. At the same time, the left and right movable frames 11 moving in the direction of moving away from each other and reset drive the left and right piston rods 194 to move in the direction of moving away from each other and reset. The reset of the piston rod 194 pumps the air in the left and right buffer airbags 19 back into the cylinder block 193 through the hose 191. As the air is pumped away, the buffer airbag 19 contracts and resets. In this way, it is possible to prevent the arc-shaped clamping plate 13 from making hard contact with the head shell for clamping, resulting in wear of the head shell, thereby ensuring the complete quality of the head shell.

[0040] Please refer to Figure 10 As shown, the integrated drilling and tapping device for the casting head shell of the angle grinder further includes an electric push rod 20 and a brush plate 21. Electric push rods 20 are installed on both the vertical drilling machine 4 and the horizontal drilling machine 5, and electric push rods 20 are also installed on the left and right tapping machines 6. Brush plates 21 are fixedly connected to the ends of the telescopic rods of the four electric push rods 20. When the brush plate 21 moves, the brush plate 21 can remove the debris attached to the vertical drilling machine 4, the horizontal drilling machine 5, and the tapping machine 6.

[0041] Please refer to Figure 11 As shown, the integrated drilling and tapping device for the casting head shell of the angle grinder further includes a buffer block 22. Buffer blocks 22 are fixedly sleeved on the rear ends of the left and right positioning rods 15. The buffer block 22 is made of rubber. When the buffer block 22 moves into contact with the head shell, the buffer block 22 can buffer and protect the head shell.

[0042] After the vertical drilling machine 4, the horizontal drilling machine 5 and the tapping machine 6 are turned off, the electric push rod 20 is started. The telescopic rod of the electric push rod 20 expands and contracts to drive the brush plate 21 to move back and forth continuously. The reciprocating movement of the brush plate 21 removes the debris attached to the vertical drilling machine 4, the horizontal drilling machine 5 and the tapping machine 6. After the debris is removed, the electric push rod 20 is turned off, and the brush plate 21 is in its original position. In this way, it can prevent a large amount of debris from adhering to the vertical drilling machine 4, the horizontal drilling machine 5 and the tapping machine 6 and affecting the subsequent use effect, thus ensuring the subsequent use effect of the vertical drilling machine 4, the horizontal drilling machine 5 and the tapping machine 6.

[0043] When the positioning rod 15 moves backward, the positioning rod 15 drives the buffer block 22 to move backward. The buffer block 22 moves backward and contacts the head shell. The positioning rod 15 corrects and positions the head shell through the buffer block 22. Since the positioning rod 15 contacts the head shell first, it is necessary to keep pressing on the head shell all the time, and the buffer block 22 protects the head shell. When the positioning rod 15 moves forward and resets, the positioning rod 15 drives the buffer block 22 to move forward and reset, and the buffer block 22 resets and disengages from the head shell. In this way, it can prevent the positioning rod 15 from pressing on the head shell and causing damage, thereby further ensuring the safety of the head shell.
