Description

Technical Field

[0001] The present invention relates to the technical field of gear processing, and in particular to a gear processing device. Background Art

[0002] A gear with a shaft, also known as a gear shaft, is a mechanical component in which the gear and shaft are designed as a single unit. In this design, the gear and shaft are not separate parts, but are instead formed into a single component through processes such as casting, forging, or machining. This design offers advantages such as high strength, excellent precision, and high reliability.

[0003] In order to be able to install the gear shaft on the shaft that drives the gear shaft to rotate and ensure that the two can be fixedly connected, the following processing is usually required on the gear shaft:

[0004] 1. Center hole: Drill the center hole used to position and support the gear shaft, so that it can be installed on the shaft that drives it to rotate.

[0005] 2. Side hole: A side hole is machined on the side of the gear shaft to achieve a fixed connection between the gear shaft and the drive shaft.

[0006] 3. Circumferential blind holes: Blind holes are machined at intervals on the circumference of the gear. These blind holes can be used as lubrication holes, pressure balance holes, mounting holes, process holes and weight reduction holes.

[0007] Although there are currently machine tools capable of machining center holes, side holes, and blind holes in gear shafts, these machines are generally only capable of machining one type of hole. Therefore, to complete all hole types, the gear shaft must be transferred back and forth between multiple machine tools, which not only reduces machining efficiency but also increases production costs.

A chip removal port 202 is provided on the top of the machine 1, which is located just below the cylinder 16. Two guide rods 14 are symmetrically connected to the top of the machine 1 with the chip removal port 202 as the symmetrical center.

[0036] See also Figure 2-Figure 4The pushing member 9 includes a U-shaped block 92 that is slidably connected to the guide rail 8. The inner bottom surface of the U-shaped block 92 is slidably connected to a clamping block 93 through a sliding groove. Two left and right springs 94 are connected between the rear side wall of the clamping block 93 and the rear inner wall of the U-shaped block 92. The top of the machine 1 is connected to an electric push rod 91 located on the front side of the guide rail 8. The telescopic rod of the electric push rod 91 is connected to the U-shaped block 92. The rear side of the guide rail 8 is connected to an L-shaped top block 81. The height of the top of the rear side of the U-shaped block 92 is lower than the inner top of the top block 81. The front top of the U-shaped block 92 and the top of the clamping block 93 are both flush with the top of the top block 81.

[0037] See also Figure 5-Figure 8 The driving mechanism includes two front and rear swing plates 201 hinged on the top of the machine 1. The swing plates 201 are L-shaped. The two swing plates 201 are located on the outside of the two guide rails 18 and on the inside of the two guide rods 14. A torsion spring 202 is installed at the hinge point between the swing plate 201 and the machine 1. A slot 203 is opened on the left side of the swing plate 201. Short rods 204 are connected to the outer walls of the front and rear sides of the C-shaped support plate 19. The two short rods 204 are respectively located in the slots 203 of the two swing plates 201. Two front and rear L-shaped push plates 205 are slidably connected to the lifting plate 13. The two L-shaped push plates 205 are respectively in contact with the two L-shaped swing plates 201. The top of the lifting plate 13 is connected to an L-shaped connecting plate 20 6. A spring three 207 is connected between the push plate 205 and the connecting plate 206. Two front and rear support rods 208 are connected to the inner top of the L-shaped connecting plate 206. The two support rods 208 are respectively slidably connected to the upper parts of the two push plates 205. The two springs three 207 are respectively sleeved on the two support rods 208. The support rods 208 are used to support the spring three 207 to prevent the spring three 207 from bending when it is deformed. The right end of the guide rail two 18 is connected to a positioning block 22 for positioning the C-shaped support plate 19. The right side of the swing plate 201 is rotatably connected to the contact wheel 23. The contact wheel 23 can reduce the friction between the swing plate 201 and the push plate 205, thereby reducing the wear between the two, so as to extend the service life of the swing plate 201 and the push plate 205.

[0038] The gear shaft 28 to be processed is placed manually or by a robot on the guide channel 2. The shaft of the gear shaft 28 is then located inside the guide channel 2, and the gear on the gear shaft 28 is located on the upper side of the top surface of the guide channel 2. The control pusher 2 10 is operated to push the gear shaft 28 on the guide channel 2 to the right, so that the gear shaft 28 at the rightmost end of the guide channel 2 is pushed rightward onto the U-shaped block 92. The gear on the gear shaft 28 is then located on the upper side of the U-shaped block 92 and the clamping block 93, while the shaft of the gear shaft 28 is located inside the U-shaped block 92 and at a certain distance from the inner bottom surface of the U-shaped block 92, so as to facilitate the subsequent processing of the center hole. By controlling the electric push rod 191 to drive the U-shaped block 92 to move backward, the spring 194, the clamping block 93 and the gear shaft 28 can be driven to move backward, so as to push the gear shaft 28 backward to the bottom of the electric drill 15. When the clamping block 93 moves backward to contact the L-shaped top block 81, the clamping block 93 cannot move further backward, so that the U-shaped block 92 continues to move backward to stretch the spring 194. Through the cooperation of the spring 194 and the clamping block 93, the shaft on the gear shaft 28 is clamped and fixed in the U-shaped block 92 to fix the gear shaft 28, ensuring that the subsequent electric drill 15 center hole processing operation and the electric drill 27 side hole processing operation can be carried out smoothly. Next, electric drill 5 is controlled to rotate, and then electric slide 4 is controlled to drive electric drill 5 to move back and forth downward and upward. The downward movement of electric drill 5 drives the lower pressure piece 15 downward, pressing and fixing gear shaft 28 on U-shaped block 92 and clamping block 93, thereby securing gear shaft 28 more firmly. Electric drill 5 then continues to move downward to machine a center hole in gear shaft 28. After electric drill 5 is removed from the center hole in gear shaft 28, electric drill 2 7 is controlled to rotate. Simultaneously, electric slide 2 6 is controlled to drive electric drill 2 7 toward gear shaft 28, machining a side hole in gear shaft 28. At this time, gear shaft 28 is still fixed by lower pressure piece 15 and clamping block 93. After the side hole is machined, electric slide rail 26 is controlled to drive electric drill 27 away from gear shaft 28 and remove it from the side hole. Once electric drill 15 is completely removed from the center hole of gear shaft 28, it continues to move upward, driving down-pressing member 15 upward and disengaging it from gear shaft 28. Electric push rod 1 91 is then controlled to drive U-shaped block 92 forward, driving spring 1 94, clamping block 93, and gear shaft 28 forward, aligning the machined gear shaft 28 forward with the C-shaped support plate 19. After clamping block 93 disengages forward from top block 81, spring 1 94 returns the clamping block 93 backward, disengaging the shaft on gear shaft 28. The machined gear shaft 28 is then pushed rightward onto the C-shaped support plate 19, its shaft now positioned inside the C-shaped support plate 19, while the gear on gear shaft 28 is positioned above the top surface of the C-shaped support plate 19.

[0039] The electric push rod 3 12 is controlled to drive the lifting plate 13, which drives the cylinder 16 and the connecting plate 206 to move reciprocally downward and upward. At the same time, the motor 221 is controlled to operate. The motor 221 drives the drill bit 17 to rotate through the gear set 222. The connecting plate 206 moves downward, which in turn pushes the push plate 205 downward via the spring 3 207. The push plate 205 moves downward, pushing the swing plate 201 to the right. The torsion spring 202 is compressed, and the swing plate 201 swings rightward, pushing the short rod 204 through the slot 203 on the swing plate 201, which then moves the C-shaped support plate 19 to the right. The short rod 204 then slides within the slot 203. After the C-shaped support plate 19 moves to the right and contacts the positioning block 22, the C-shaped support plate 19 cannot move further to the right, and thus the swing plate 201 cannot swing further to the right. The push plate 205 cannot move further downward. As a result, the connecting plate 206 continues to move downward along with the lifting plate 13, compressing the spring 3 207. The C-shaped support plate 19 moves rightward, driving the gear shaft 28 on it to move rightward to the bottom of the drill bit 17. After the gear shaft 28 moves to the bottom of the drill bit 17, the cylinder 16 drives the second pressing piece 21 to continue to move downward to press the gear shaft 28 and fix it on the C-shaped support plate 19, ensuring that the subsequent blind hole processing operation of the drill bit 17 can be carried out smoothly. Then the cylinder 16 drives the drill bit 17 to continue to move downward to process a blind hole on the gear of the gear shaft 28. When the cylinder 16 drives the drill bit 17 to be pulled upward from the blind hole on the gear shaft 28, the second pressing piece 21 keeps pressing the gear shaft 28 to prevent the displacement of the gear shaft 28 from affecting the extraction of the drill bit 17. When the drill bit 17 is completely pulled upward from the blind hole of the gear shaft 28, the cylinder 16 moves upward, driving the second pressing piece 21 to move upward and disengage from the gear shaft 28. As the connecting plate 206 follows the lifting plate 13 to move upward, spring three 207 slowly returns to its original state, and the push plate 205 will not move up immediately. After the lower pressure piece 21 moves upward and disengages from the gear shaft 28, spring three 207 completely returns to its original state, and the connecting plate 206 continues to move upward and pulls the push plate 205 upward and reset through spring three 207. Under the reset action of the torsion spring 202, the swing plate 201 swings to the left and resets. The swing plate 201 swings to the left and pushes the short rod 204 with the C-shaped support plate 19 to move to the left through the upper groove 203, thereby driving the completed gear shaft 28 to move to the left, and then the completed gear shaft 28 can be removed.In this way, the present device can push the gear shaft 28 on the guide channel 2 to the pushing member 10, and can push the gear shaft 28 to be aligned with the electric drill 1 5 and the electric drill 2 7 through the pushing member 10, and process a center hole on the gear shaft 28 through the electric drill 5, and process a side hole on the shaft of the gear shaft 28 through the electric drill 27. The gear shaft 28 processed on the pushing member 9 is pushed to the C-shaped support plate 19 by the pushing member 2 10, and the C-shaped support plate 19 is driven by the driving mechanism to move and transport the processed gear shaft 28 to the bottom of the drill bit 17, and a blind hole is processed on the gear of the gear shaft 28 through the drill bit 17. Therefore, the present device has the ability to process center holes, side holes and blind holes, and there is no need to equip multiple machine tools to realize the processing of center holes, side holes and blind holes, and there is no need to transfer the gear shaft 28 back and forth between multiple machine tools, which can significantly improve processing efficiency and reduce production costs.

[0040] See also Figure 2 The pushing member 10 includes an electric push rod 101 installed on the top of the machine 1 and on the left side of the guide channel 2. A T-shaped push block 102 is connected to the telescopic rod of the electric push rod 101. The T-shaped push block 102 is located in the guide channel 2. By controlling the electric push rod 101 to drive the push block 102 to move to the right, the gear shaft 28 on the guide channel 2 can be pushed to the right, so that the gear shaft 28 at the rightmost end of the guide channel 2 can be pushed to the right onto the U-shaped block 92. The electric push rod 101 is controlled to drive the push block 102 to move to the left so that the next gear shaft 28 to be processed can be placed on the guide channel 2.

[0041] See also Figure 4 The lower pressure piece 15 includes a connecting ring 151 connected to the outer shell of the electric drill 5. Two lifting rods 152 are slidably connected to the connecting ring 151 at circumferential intervals. A pressure ring 153 is connected between the bottom ends of the two lifting rods 152. A spring 2 154 is sleeved on the lifting rod 152. The two ends of the spring 2 154 are respectively connected to the pressure ring 153 and the connecting ring 151.

[0042] The downward movement of electric drill 15 drives pressure ring 153 downward. When pressure ring 153 contacts gear shaft 28 on U-shaped block 92, pressure ring 153 and lifting rod 152 cannot move further downward. Connecting ring 151 then moves downward with electric drill 15, compressing spring 2 154. The cooperation between spring 2 154 and pressure ring 153 holds gear shaft 28 against U-shaped block 92 and clamping block 93, preventing gear shaft 28 from shifting when electric drill 15 subsequently machines the center hole in gear shaft 28, thus ensuring smooth center hole machining. As electric drill 15 moves upward, spring 2 154 slowly returns to its original position, allowing pressure ring 153 to maintain pressure on gear shaft 28, preventing displacement of gear shaft 28 from interfering with the removal of electric drill 15. After electric drill 1 (5) is removed from the center hole of gear shaft 28, two electric drills (2) (7) approach each other to drill side holes in gear shaft 28. Gear shaft 28 is still held in place by pressure ring 153, ensuring smooth side hole drilling. Once electric drill 1 (5) is completely removed from the center hole of gear shaft 28, spring 2 (154) returns to its original position. Connecting ring 151 then continues upward, following electric drill 1 (5). Spring 2 (154) pulls pressure ring 153 upward and away from gear shaft 28, causing lifting rod 152 to move upward and return to its original position. At this point, gear shaft 28 is still held in place by clamping block 93 within U-shaped block 92, preventing any subsequent removal of electric drill 2 (7).

[0043] See also Figure 6-Figure 7 The lower pressing member 21 includes a lifting rod 211 slidably connected to the bottom of the cylinder 16. The bottom end of the lifting rod 211 is connected to a pressure block 212. A spring 213 is sleeved on the lifting rod 211. The two ends of the spring 213 are respectively connected to the pressure block 212 and the cylinder 16. The lifting rod 211, the pressure block 212 and the spring 213 are all located on the inner side of the drill bit 17.

[0044] The cylinder 16 moves downward and drives the pressure block 212 to move downward through the lifting rod 211. When the pressure block 212 moves downward and contacts the gear shaft 28 on the C-shaped support plate 19, the lifting rod 211 and the pressure block 212 cannot move further downward, so that the cylinder 16 continues to press down to compress the spring four 213. The gear shaft 28 is pressed and fixed on the C-shaped support plate 19 through the cooperation of the spring four 213 and the pressure block 212 to avoid the gear shaft 28 from being displaced when the drill bit 17 subsequently machines a blind hole on the gear of the gear shaft 28, thereby ensuring that the blind hole machining operation of the gear shaft 28 proceeds smoothly. When the cylinder 16 moves upward, the spring four 213 slowly returns to its original state. At this time, the pressure block 212 continues to press the gear shaft 28 to prevent the displacement of the gear shaft 28 from affecting the removal of the drill bit 17. When the cylinder 16 drives the drill bit 17 to be pulled upward from the blind hole on the gear shaft 28, the spring four 213 completely returns to its original state. Then the cylinder 16 continues to move upward, pulling the pressure block 212 upward and disengaging from the gear shaft 28 through the spring four 213, and the lifting rod two 211 moves upward and resets.

[0045] See also Figures 9-11 The top of the machine 1 is connected to a gantry 24 located between the guide rail 1 8 and the lifting plate 13. The top of the machine 1 is provided with a conveyor belt 27 located inside the gantry 24. An electric slide rail 3 25 is installed on the top of the inner side of the gantry 24. An electric lifting fixture 26 is provided on the slider of the electric slide rail 3 25 to clamp the processed gear shaft 28 and place it on the conveyor belt 27. The electric lifting fixture 26 includes an electric push rod 4 260 installed on the slider of the electric slide rail 3 25. The telescopic rod of the electric push rod 4 260 is connected to the mobile frame 26. 1. The top of the mobile frame 261 is connected to two front and rear sliding rods, which are slidably connected to the slider of the electric slide rail 3 25. The sliding rod is used to guide the mobile frame 261 to rise and fall. The mobile frame 261 is slidably connected to two front and rear slotted wedge blocks 262 through a slide groove. The bottoms of the two slotted wedge blocks 262 are connected to a clamping block 263. The mobile frame 261 is installed with an electric push rod 5 265. The telescopic rod of the electric push rod 5 265 is connected to a trapezoidal block 264. The trapezoidal block 264 is slidably connected to the grooves of the two slotted wedge blocks 262.

[0046] When the C-shaped support plate 19 drives the gear shaft 28 to move to the left and reset after the drilling process is completed, the gear shaft 28 is then located between the front and rear clamping blocks 263. First, the electric push rod 5 265 is controlled to drive the trapezoidal block 264 to move upward. The trapezoidal block 264 moves upward and pulls the two slotted wedge blocks 262 with the two clamping blocks 263 close to each other to clamp the gear shaft 28. Then control the electric push rod four 260 to drive the movable frame 261 to move upward, so that the clamping block 263 drives the gear shaft 28 to move upward and disengage from the C-shaped support plate 19, and then control the electric slide rail three 25 to drive the entire electric lifting fixture 26 to move forward to move the gear shaft 28 to the upper side of the conveyor belt 27, and then control the electric push rod four 260 to drive the movable frame 261 to move downward, so that the clamping block 263 moves downward to place the gear shaft 28 on the conveyor belt 27, and then control the electric push rod five 265 to drive the trapezoidal block 264 to move downward, and the trapezoidal block 264 moves downward to push the two slotted wedge blocks 262 and the two clamping blocks 263 away from each other to release the gear shaft 28, and finally control the electric slide rail three 25 to drive the entire electric lifting fixture 26 to move backward and reset. The conveyor belt 27 can rotate to transport the gear shaft 28 with the drilling completed to the next process. In this way, the equipment can automatically complete the unloading and transport the gear shaft 28 after the processing to the next process. There is no need for manual unloading, which can save time and effort and improve processing efficiency.
