Description

Technical Field

[0001] The 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 called a gear shaft, refers to a mechanical component that designs the gear and shaft as an integral whole. In this design, the gear and shaft are not separate parts, but are made into a single component through processes such as casting, forging or machining. This design has the advantages of high strength, good precision and strong reliability.

[0003] In order 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: 1. Center hole: Drill the center hole used to locate and support the gear shaft, so that it can be installed on the shaft that drives it to rotate.

[0004] 2. Side hole: A side hole is machined on the side surface of the gear shaft to achieve a fixed connection between the gear shaft and the drive shaft.

[0005] 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.

[0006] Although there are machine tools that can process the center hole, side hole and blind hole of the gear shaft respectively, the existing machine tools can generally only process one type of hole. Therefore, in order to complete all types of hole processing, the gear shaft needs to be transferred back and forth between multiple machine tools, which not only reduces processing efficiency but also increases production costs.

[0035] 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. The lifting plate 13 is slidably connected with two front and rear L-shaped push plates 205. 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 with 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 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.

[0036] The gear shaft 28 to be processed is placed on the guide channel 2 manually or by a robot, and the shaft on the gear shaft 28 is then located in 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 can push the gear shaft 28 on the guide channel 2 to the right, so as to push the rightmost gear shaft 28 on the guide channel 2 to the right onto the U-shaped block 92, and the gear on the gear shaft 28 is then located on the top upper side of the U-shaped block 92 and the clamping block 93, and the shaft on the gear shaft 28 is located in the U-shaped block 92 and is 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 91 to drive the U-shaped block 92 to move backward, the spring 94, 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 5. When the clamping block 93 moves backward to contact with the L-shaped top block 81, the clamping block 93 cannot move backward any further, so that the U-shaped block 92 continues to move backward to stretch the spring 94. Through the cooperation of the spring 94 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, thereby ensuring that the subsequent center hole machining operation of the electric drill 5 and the side hole machining operation of the electric drill 27 can proceed smoothly. Then, the electric drill 5 is controlled to rotate, and then the electric slide rail 4 is controlled to drive the electric drill 5 to move back and forth downward and upward. The electric drill 5 moves downward to drive the lower pressing piece 15 to move downward to press the gear shaft 28 and fix it on the U-shaped block 92 and the clamping block 93, so that the gear shaft 28 is fixed more firmly. The electric drill 5 then continues to move downward to machine a center hole on the gear shaft 28. When the electric drill 5 is pulled out of the center hole on the gear shaft 28, the electric drill 27 is controlled to rotate. At the same time, the electric slide rail 26 is controlled to drive the electric drill 27 to move in the direction close to the gear shaft 28, and a side hole is machined on the gear shaft 28. At this time, the gear shaft 28 is still fixed by the lower pressing piece 15 and the clamping block 93. After the side hole processing is completed, the electric slide rail 26 is controlled to drive the electric drill 27 to move away from the gear shaft 28 and pull it out from the side hole. When the electric drill 15 is completely pulled out from the center hole of the gear shaft 28, the electric drill 15 continues to move upward to drive the lower pressing piece 15 to move upward and disengage from the gear shaft 28. Then the electric push rod 191 is controlled to drive the U-shaped block 92 to move forward, so as to drive the spring 194, the clamping block 93 and the gear shaft 28 to move forward, so that the processed gear shaft 28 is aligned with the C-shaped support plate 19 forward. When the clamping block 93 is disengaged from the top block 81 forward, the clamping block 93 is pulled backward to disengage from the shaft on the gear shaft 28 under the reset action of the spring 194. The processed gear shaft 28 is then pushed rightward onto the C-shaped support plate 19, and the shaft on the gear shaft 28 is then located on the inner side of the C-shaped support plate 19, and the gear on the gear shaft 28 is located on the upper side of the top surface of the C-shaped support plate 19.

[0037] The electric push rod 3 12 is controlled to drive the lifting plate 13 to drive the cylinder 16 and the connecting plate 206 to move downward and upward reciprocatingly, and the motor 221 is controlled to work. The motor 221 works to drive the drill bit 17 to rotate through the gear set 222. The connecting plate 206 moves downward to push the push plate 205 downward through the spring 3 207. The push plate 205 moves downward to push the swing plate 201 to swing to the right, and the torsion spring 202 is compressed accordingly. The swing plate 201 swings to the right and pushes the short rod 204 to move the C-shaped support plate 19 to the right through the slot 203 on it. The short rod 204 slides in the slot 203 accordingly. After the C-shaped support plate 19 moves to the right and contacts the positioning block 22, the C-shaped support plate 19 cannot continue to move to the right, so that the swing plate 201 cannot continue to swing to the right, and the push plate 205 cannot continue to move downward, and then the connecting plate 206 follows the lifting plate 13 to continue to move downward to compress the spring 3 207. The C-shaped support plate 19 moves rightwards and drives the gear shaft 28 on it to move rightwards 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 downwards 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 is carried out smoothly. Then, the cylinder 16 drives the drill bit 17 to continue to move downwards 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 upwards 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 pulling out of the drill bit 17. When the drill bit 17 is completely pulled upwards from the blind hole of the gear shaft 28, the cylinder 16 moves upwards and drives the second pressing piece 21 to move upwards and disengage from the gear shaft 28. When the connecting plate 206 follows the lifting plate 13 to move upward, the spring three 207 slowly returns to its original state, and the push plate 205 does not move up immediately. After the lower pressure piece 21 moves upward and disengages from the gear shaft 28, the spring three 207 completely returns to its original state, and the connecting plate 206 continues to move upward, pulling the push plate 205 upward and returning to its original state through the spring three 207. Under the returning action of the torsion spring 202, the swing plate 201 swings to the left and returns to its original state. 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 straight groove 203 on it, thereby driving the processed gear shaft 28 to move to the left, and then the processed gear shaft 28 can be removed.In this way, the device can push the gear shaft 28 on the guide channel 2 to the pushing member 19 through the pushing member 2 10, and can push the gear shaft 28 to align with the electric drill 1 5 and the electric drill 2 7 through the pushing member 19, 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 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 device has the ability to process center holes, side holes and blind holes, and there is no need to be equipped with 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 the processing efficiency and reduce the production cost.

[0038] See also Figure 2 The pushing member 10 includes an electric push rod 101 installed on the top of the machine 1 and located 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. The electric push rod 101 is controlled to drive the push block 102 to move right, so that 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 left, so that the next gear shaft 28 to be processed can be placed on the guide channel 2.

[0039] See also Figure 4 The lower pressing member 15 includes a connecting ring 151 connected to the outer shell of the electric drill 5, and two lifting rods 152 are slidably connected to the connecting ring 151 at a circumferential interval, and a pressing 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, and the two ends of the spring 2 154 are respectively connected to the pressing ring 153 and the connecting ring 151.

[0040] The downward movement of the electric drill 15 drives the pressing ring 153 downward. When the pressing ring 153 moves downward and contacts the gear shaft 28 on the U-shaped block 92, the pressing ring 153 and the lifting rod 152 cannot move downward further, so the connecting ring 151 follows the electric drill 15 to continue to move downward to compress the spring 2 154. The gear shaft 28 is pressed and fixed on the U-shaped block 92 and the clamping block 93 through the cooperation of the spring 2 154 and the pressing ring 153 to prevent the gear shaft 28 from being displaced when the electric drill 15 subsequently processes the center hole on the gear shaft 28, thereby ensuring that the center hole processing operation of the gear shaft 28 proceeds smoothly. When the electric drill 15 moves upward, the spring 2 154 slowly returns to its original state. At this time, the pressing ring 153 keeps pressing the gear shaft 28 to prevent the displacement of the gear shaft 28 from affecting the removal of the electric drill 15. When the electric drill 1 5 is pulled out from the center hole on the gear shaft 28, the two electric drills 2 7 approach each other to process the side holes on the gear shaft 28. The gear shaft 28 is still pressed and fixed by the pressure ring 153 at this time, which can ensure that the side hole processing operation of the gear shaft 28 can be carried out smoothly. When the electric drill 1 5 is completely pulled out from the center hole of the gear shaft 28, the spring 2 154 is completely restored to its original state, and then the connecting ring 151 continues to move up with the electric drill 1 5, and the pressure ring 153 is pulled up and separated from the gear shaft 28 by the spring 2 154, and the lifting rod 1 152 moves up and resets accordingly. At this time, the gear shaft 28 is still pressed and fixed in the U-shaped block 92 by the clamping block 93, which will not affect the subsequent pulling out of the electric drill 2 7.

[0041] 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, and 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.

[0042] The cylinder 16 moves downward, driving 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 downward 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 prevent 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 keeps pressing 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 and pulls the pressure block 212 upward and disengages from the gear shaft 28 through the spring four 213, and the lifting rod two 211 moves upward and resets accordingly.

[0043] See also Figure 9-11 A gantry 24 located between the guide rail 1 8 and the lifting plate 13 is connected to the top of the machine 1, and a conveyor belt 27 located inside the gantry 24 is provided on the top of the machine 1. 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, which is used 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, and a mobile frame 26 is connected to the telescopic rod of the electric push rod 4 260. 1. The top of the mobile frame 261 is connected to two front and rear sliding bars, which are slidably connected to the slider of the electric slide rail 3 25. The sliding bar 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 both connected to a clamping block 263. An electric push rod 5 265 is installed on the mobile frame 261. 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.

[0044] 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 after drilling to the next process. In this way, the equipment can automatically complete the unloading and transport the processed gear shaft 28 to the next process without manual unloading, which can save time and effort and improve processing efficiency.

It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
