Description

Technical Field

[0001] The invention belongs to the field of speed reducer shaft processing and positioning, and in particular relates to a speed reducer shaft processing clamping device. Background Art

[0002] The reducer shaft is a key component in the reducer, primarily used to transmit torque and support rotating parts. It is typically a cylindrical metal shaft, but its shape and size vary depending on the reducer type and usage requirements.

[0003] In some equipment with weight-sensitive requirements, such as reducers in aerospace, electric vehicles, and other fields, the use of hollow shafts can effectively reduce the overall weight of the reducer without compromising the shaft's strength and rigidity, thereby improving the equipment's performance and efficiency. During machining, this hollow reducer shaft must be clamped and fixed before drilling along its central axis using a drill rod.

[0004] At present, many reducer shafts are clamped and fixed using a V-groove combined with a pressure plate during processing. This clamping method has the following problems when drilling the reducer shaft: After the reducer shaft is placed in the V-groove, it is pressed and fixed on top of it by multiple spaced pressure plates according to the length of the reducer shaft. When the drill rod is drilled along the axis of the reducer shaft, when the hole is drilled to the pressure position of the pressure plate, the inside of the reducer shaft at the pressure position of the pressure plate changes from the original solid structure to a hollow structure. At this time, the pressure applied by the pressure plate in this area may cause the surface of the reducer shaft at this position to be concave and deformed, thereby causing the reducer shaft to be scrapped.

[0028] The following is combined with Figure 1 -Attached Figure 10 This application is described in further detail.

[0029] Please refer to Figure 1 、 Figure 2 and Figure 4 A reducer shaft machining clamping device, used in conjunction with a reducer shaft drilling device when drilling a reducer shaft, comprises a clamping seat 1 having a V-shaped groove extending along its length on its upper side. The clamping seat 1 is equipped with multiple clamping mechanisms 2, and side blocks 3 are provided within the V-shaped groove. The reducer shaft is placed within the V-shaped groove, and then the multiple clamping mechanisms 2 apply pressure to the reducer shaft at multiple points, while the side blocks 3 provide support against the rear end of the reducer shaft.

[0030] See Figure 4 A third chute is provided at the lower and rearward portion of the V-shaped groove. The side stop mechanism 3 includes an adjusting screw 31 rotatably disposed within the third chute. One end of the adjusting screw 31 movably penetrates the rear outer wall of the clamping seat 1 and is fixedly connected to an adjusting knob. A slider 32 is threadedly connected to the adjusting screw 31. The slider 32 is slidably disposed within the third chute, and a side stop 33 is fixedly disposed on the upper side of the slider 32. Rotating the adjusting screw 31 causes the slider 32 to move along the third chute, driving the side stop 33 to move. The side stop 33 is adjusted according to the length of the reducer shaft so as to contact the rear end of the reducer shaft.

[0031] See Figure 1 and Figure 5 The clamping mechanism 2 includes a mounting plate 21 movably mounted on the upper side of the clamping base 1. A pressing assembly 22 for securing the reducer shaft surface is mounted on the mounting plate 21. A resisting portion 23 is mounted on the pressing assembly 22, and a locking assembly 24 is mounted on the resisting portion 23. An unlocking assembly 25 is connected between the clamping base 1 and the external drilling device, unlocking each unlocking assembly 25 in sequence from front to back.

[0032] See Figure 1 、 Figure 3 and Figure 4 A guide groove 11 with a bilaterally symmetrical and convex cross-section is provided on the upper side of the clamping seat 1. A guide block 4 adapted to the guide groove 11 is fixedly provided on the lower side of the lower horizontal section of the mounting plate 21, and the guide block 4 is slidably set in the guide groove 11.

[0033] See Figure 3 A locking member 5 is provided on the upper side of the lower horizontal section of the mounting plate 21 for horizontally locking the mounting plate 21. The locking member 5 is configured as a spring locking pin. The upper side of the clamping base 1 is provided with a plurality of evenly distributed positioning slots along its length. The lower end of the spring locking pin movably penetrates the corresponding lower horizontal section of the mounting plate 21 and movably engages with the positioning slot.

[0034] During operation, the number and position of the clamping mechanisms 2 on the clamping base 1 can be adjusted according to the material of the reducer shaft and the drill hole diameter. Specifically, the guide block 4 slides into the guide groove 11, allowing the mounting plate 21 to slide and adjust its position on the clamping base 1. After adjusting to the appropriate position, the spring locking pin can be inserted into the corresponding positioning groove to limit the horizontal direction of the mounting plate 21, thereby fixing the position of the mounting plate 21. This ensures the stability of the clamping mechanism 2 during drilling, while facilitating disassembly and assembly, and adjusting the number of clamping mechanisms 2 as needed.

[0035] See Figure 3 、 Figure 5 and Figure 6 The lower pressing assembly 22 includes a guide seat 221 fixedly arranged on the lower side of the horizontal section of the mounting plate 21. A slide groove 1 is opened on the lower side of the guide seat 221. A clamping screw 222 is rotatably arranged on the upper inner wall of the slide groove 1. The upper end of the clamping screw 222 movably passes through the horizontal section of the mounting plate 21 and is fixedly connected to a rotating handle. The lower end of the clamping screw 222 is threadedly connected to a lower pressing seat 223. The lower pressing seat 223 is slidably arranged in the slide groove 1 and is connected to the corresponding interference part 23. By rotating the clamping screw 222, the interference part 23 is driven to move downward, and the interference part 23 presses and fixes the reducer shaft in the V-groove.

[0036] See Figure 5 、 Figure 6 and Figure 7The abutment portion 23 includes a rectangular connection seat 231 fixedly connected to the lower pressure seat 223. A movable cavity is defined within the connection seat 231, within which a slide 232 is slidably disposed. A compression block 233, which movably extends through the lower inner wall of the movable cavity, is fixedly connected to the lower side of the slide 232. A return spring 1 234 is fixedly connected to the upper side of the slide 232. The upper end of the return spring 1 234 is fixedly connected to the upper inner wall of the movable cavity. A worker can pull down the compression block 233, causing the slide 232 to slightly move downward within the movable cavity while the connection seat 231 remains stationary, thereby placing the return spring 1 234 in a stretched state.

[0037] See Figure 5-Figure 9 The left and right sides of the connecting seat 231 are provided with a slide groove 2, and the two corresponding slide grooves 2 on the left and right sides are provided with a slide hole connected to the corresponding active cavity. The locking assembly 24 includes two iron slide plates 241, and the slide plate 241 is slidably connected to the corresponding slide groove 2. The left and right corresponding slide plates 241 are fixedly provided with a limit pin 242 on one side close to each other, and the limit pin 242 is slidably connected to the corresponding slide hole. The left and right sides of the slide seat 232 are provided with a limit groove matching the limit pin 242. The front and rear sides of the slide plate 241 are fixed with guide posts 243 symmetrically arranged in the upper and lower parts through the ear seat 1. The front and rear sides of the connecting seat 231 are fixed with four ear seats 2 distributed in a matrix. The guide posts 243 are movably plugged into the corresponding ear seats 2, and the surface of the guide posts 243 is sleeved with a return spring 244, and the two ends of the return spring 244 are fixedly connected to one side of the ear seat and the surface of the guide post 243 respectively. The operator pulls the clamping block 233 downward, aligning the stop slot on the slide 232 with the corresponding stop pin 242. Under the action of the second return spring 244 (in a stretched state), the stop pin 242 is inserted into the stop slot, locking the slide 232 and the clamping block 233 below it. At this point, the clamping block 233 no longer moves relative to the connecting seat 231. The clamping block 233 is then moved downward by rotating the clamping screw 222, securing the reducer shaft.

[0038] See Figure 6 and Figure 7 A plurality of guide balls 6 are rotatably mounted on the surface of the stop pin 242 and the stop slot. The guide balls 6 roll against the inner wall of the corresponding stop slot. The guide balls 6 replace the stop pin 242 and connect to the inner wall of the stop slot, allowing the stop pin 242 to limit the vertical position of the slide 232 while reducing the friction between the stop pin 242 and the stop slot when the stop pin 242 slides horizontally.

[0039] See Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 10The unlocking component 25 includes two guide frames 251 fixed in the V-shaped groove by a bracket and symmetrical on the left and right. A driven push rod 252 is slidably inserted on the front side of the guide frame 251. The rear end of the driven push rod 252 is fixedly connected to an electromagnetic suction plate 253. The electromagnetic suction plate 253 is slidably connected to the corresponding guide frame 251. Two active push rods 254 symmetrical on the left and right are also provided on the front side of the clamping seat 1. The two active push rods 254 are both connected to the external drilling device. When drilling, the external drilling device will synchronously drive the two active push rods 254 to move in the direction of the driven push rod 252. As the drilling continues to go deeper, the active push rod 254 will push the driven push rod 252, so that the driven push rod 252 drives the electromagnetic suction plate 253 to move. After the electromagnetic suction plate 253 is energized, an adsorption force is generated. As it continues to move, an adsorption force is generated on each iron slide 241 on the moving path, driving the slide 241 to slide outward so that the limit pin 242 slides out of the corresponding limit groove, releasing the lock on the slide 232. At this time, the slide 232 moves slightly upward under the action of the return spring 234, so that the clamping block 233 below no longer conflicts with the reducer shaft and generates pressure. After the subsequent drill rod drilling, the reducer shaft will not be deformed at this position due to the pressure of the clamping block 233.

[0040] See Figure 2 The rear end of the active push rod 254 is fixedly provided with an electromagnetic suction cup 255, and the front end of the driven push rod 252 is fixedly provided with an iron docking plate 256. The docking plate 256 movably contacts the corresponding electromagnetic suction cup 255. After the electromagnetic suction cup 255 and the docking plate 256 contact, they can be adsorbed together, so that when the active push rod 254 is subsequently reset, it can pull the driven push rod 252 to drive the electromagnetic suction plate 253 to reset.

[0041] During the specific work: the staff pulls down the clamping block 233 so that the clamping block 233 drives the slide 232 to move downward, so that the limit groove on the slide 232 is aligned with the corresponding limit pin 242, and the limit pin 242 is inserted into the limit groove under the action of the reset spring 244 to limit the slide 232. The same method is used to adjust all the clamping blocks 233.

[0042] The staff then rotates the adjusting screw 31, causing the lower pressure seat 223 to move the connecting seat 231 downward, so that the pressing block 233 below the connecting seat 231 contacts the surface of the reducer shaft, thereby fixing the reducer shaft. Multiple pressing blocks 233 are distributed along the length of the reducer shaft, with the rearmost pressing block 233 at the rear end of the reducer shaft.

[0043] During drilling, the drilling machine drives the drill rod to move toward the reducer shaft, drilling the reducer shaft and gradually going deeper. As the drill rod goes deeper, before the drill rod moves to just below the first clamping block 233, the left and right electromagnetic suction plates 253 are energized to adsorb the corresponding slides 241, causing the slides 241 to slide outward, driving the limit pins 242 to move outward to release the limit on the slide seat 232 at that position. The slide seat 232 moves upward and resets under the action of the reset spring 234, causing the clamping block 233 that originally pressed against the surface of the reducer shaft to move upward and no longer press against the reducer shaft at that position. Then the drill rod can continue to move along the length direction of the reducer shaft to drill the reducer shaft position just below the clamping block 233. As the drilling device moves, the active push rod 254 will be driven to move synchronously. The active push rod 254 will gradually approach the corresponding driven push rod 252 and eventually make the active push rod 254 push the driven push rod 252 to move together, so that the electromagnetic suction plate 253 can move along the length direction of the reducer shaft as the drilling continues to deepen, and the clamping blocks 233 on the path are unlocked one by one until the hole is drilled to a certain length before the end of the reducer shaft, and the drilling is stopped to ensure that there is at least one clamping block 233 at the end of the reducer shaft still pressing against the reducer shaft (the end of the reducer shaft is the drilling allowance, and the undrilled part can be cut off later); to avoid the surface deformation of the reducer shaft caused by the continuous pressure of the clamping block 233 after the reducer shaft is drilled into a hollow structure.

[0044] The clamping device and external drilling device work together in the following process: The reducer shaft is placed in the V-groove of the clamping seat 1, with one end of the reducer shaft contacting the side block 33. The operator then rotates the clamping screw 222 to move the clamping block 233 downward to contact the surface of the reducer shaft. Multiple clamping mechanisms 2 are provided according to the length of the reducer shaft to ensure that each small section of the reducer shaft can be equipped with a clamping block 233 for clamping and fixing during the drilling process. The same method is used to control multiple clamping blocks 233 along the reducer shaft drilling path to clamp the same reducer shaft.

[0045] During drilling, the drill rod on the external drilling device is aligned with the reducer shaft and moved to drill the hole. The front-end clamping block 233 presses the first section of the reducer shaft to fit the drill rod and drill the hole. When the drill rod approaches the clamping block 233, the clamping block 233 that is in contact with the surface of the reducer shaft below is unlocked by the unlocking assembly 25 and the locking assembly 24 releases the lock on the clamping block 233, causing the clamping block 233 to move upward and separate from the reducer shaft. At this time, the clamping block 233 no longer exerts pressure on the reducer shaft surface, and the reducer shaft is fixed by the next unlocked clamping block 233. When the drill rod moves below the unlocked clamping block 233, the reducer shaft at this position changes from a solid structure to a hollow structure and will not be deformed by the pressure of the clamping block 233.

[0046] The same method can be used to drill holes in each section of the subsequent reducer shaft.
