Description

Technical Field

[0001] The present invention belongs to the field of machining positioning of reducer shafts, and particularly relates to a clamping device for machining reducer shafts. Background Art

[0002] The reducer shaft is a key component in a reducer, mainly used for transmitting torque and supporting rotating components. It is usually a cylindrical metal shaft, and its shape and size will vary according to different reducer types and usage requirements.

[0003] In some equipment with weight requirements, such as reducers in the fields of aerospace and electric vehicles, using a hollow shaft can effectively reduce the overall weight of the reducer without affecting the strength and stiffness of the shaft, thereby improving the performance and efficiency of the equipment. When machining such a hollow reducer shaft, it needs to be clamped and fixed, and then drilled along its central axis direction by a drill rod.

[0004] Currently, when machining many reducer shafts, a method of using a V-groove in cooperation with a pressing plate is used to clamp and fix the shaft. This clamping method has the following problems when drilling the reducer shaft: After the reducer shaft is placed in the V-groove, according to the length of the reducer shaft, multiple pressing plates are distributed at intervals above it to apply pressure for fixation. When the drill rod drills along the central axis direction of the reducer shaft, when drilling to the position where the pressing plate applies pressure, the internal structure of the reducer shaft at the pressing plate application position changes from a solid structure to a hollow structure. At this time, the pressure applied by the pressing plate in this area may cause the surface of the reducer shaft at this position to be sunken and deformed, resulting in the scrapping of the reducer shaft.

Detailed implementation manners

[0028] The following further Figure 1 - with reference to the Figure 10 drawings, a detailed description of the present application will be given.

[0029] Please refer to Figure 1 , Figure 2 and Figure 4 , a clamping device for machining a reducer shaft, which is used in cooperation with a drilling device for the reducer shaft when drilling the reducer shaft. The clamping device includes a clamping seat 1. A V-shaped groove extending along the length direction thereof is formed on the upper side of the clamping seat 1. A plurality of clamping mechanisms 2 are arranged on the clamping seat 1. A side blocking mechanism 3 is arranged in the V-shaped groove. The reducer shaft is placed in the V-shaped groove, and then the reducer shaft is fixed by applying multi-point pressure through a plurality of clamping mechanisms 2, and at the same time, the rear end of the reducer shaft is abutted and supported by the side blocking mechanism 3.

[0030] Referring to Figure 4 , a third chute is formed at the rear position on the lower side of the V-shaped groove. The side blocking mechanism 3 includes an adjusting screw 31 rotatably arranged in the third chute. One end of the adjusting screw 31 movably penetrates through the outer wall at the rear side of the clamping seat 1 and is fixedly connected with an adjusting knob. A slider 32 is threadedly connected to the adjusting screw 31. The slider 32 is slidably arranged in the third chute, and a side blocking block 33 is fixedly arranged on the upper side of the slider 32. By rotating the adjusting screw 31, the slider 32 is moved along the third chute to drive the side blocking block 33 to move, and the side blocking block 33 is adjusted to abut against the rear end of the reducer shaft according to the length of the reducer shaft.

[0031] Referring to Figure 1 and Figure 5 , the clamping mechanism 2 includes a mounting plate 21 movably arranged on the upper side of the clamping seat 1. A pressing-down assembly 22 for fixing the surface of the reducer shaft is arranged on the mounting plate 21. An abutting part 23 is arranged on the pressing-down assembly 22. A locking assembly 24 is arranged on the abutting part 23. An unlocking assembly 25 for unlocking each unlocking assembly 25 in sequence from front to back is commonly connected between the clamping seat 1 and an external drilling device.

[0032] Refer to Figure 1 、 Figure 3 and Figure 4 , on the upper side of the clamping seat 1, there are symmetrically arranged left and right guiding grooves 11 with a convex cross-section. On the lower side of the lower horizontal section of the mounting plate 21, a guiding block 4 adapted to the guiding groove 11 is fixedly arranged, and the guiding block 4 is slidably arranged in the guiding groove 11.

[0033] Refer to Figure 3 , on the upper side of the lower horizontal section of the mounting plate 21, a locking member 5 for horizontally locking the mounting plate 21 is arranged. The locking member 5 is set as a spring locking pin. Along the length direction of the upper side of the clamping seat 1, a plurality of uniformly distributed positioning grooves are arranged. The lower end of the spring locking pin movably penetrates through the corresponding lower horizontal section of the mounting plate 21 and is movably inserted into the positioning groove.

[0034] During specific operation, the number and position of the clamping mechanism 2 can be adjusted on the clamping seat 1 according to the material of the reducer shaft and the drilling diameter. Specifically, when the guiding block 4 slides into the guiding groove 11, the mounting plate 21 can slide on the clamping seat 1 to adjust the position. After adjusting to the appropriate position, the mounting plate 21 can be horizontally limited by inserting the spring locking pin into the corresponding positioning groove, so that the position of the mounting plate 21 is fixed, ensuring the stability of the clamping mechanism 2 during drilling while facilitating disassembly and assembly and adjusting the number of the clamping mechanism 2 according to needs.

[0035] Refer to Figure 3 、 Figure 5 and Figure 6 , the downward pressing assembly 22 includes a guiding seat 221 fixedly arranged on the lower side of the upper horizontal section of the mounting plate 21. On the lower side of the guiding seat 221, a first sliding groove is arranged. On the upper inner wall of the first sliding groove, a pressing screw 222 is rotatably arranged. The upper end of the pressing screw 222 movably penetrates through the upper horizontal section of the mounting plate 21 and is fixedly connected with a rotating handle. The lower end of the pressing screw 222 is threadedly connected with a downward pressing seat 223. The downward pressing seat 223 is slidably arranged in the first sliding groove and is connected with the corresponding abutting part 23. By rotating the pressing screw 222, the abutting part 23 is driven to move downward, and the abutting part 23 presses and fixes the reducer shaft in the V-shaped groove.

[0036] Refer to Figure 5 、 Figure 6 and Figure 7The abutment part 23 includes a rectangular connection seat 231 fixedly connected to the lower pressing seat 223, an activity cavity is provided inside the connection seat 231, a slide seat 232 is slidably arranged in the activity cavity, a clamping block 233 that moves through the lower inner wall of the activity cavity is fixedly connected to the lower side of the slide seat 232, a return spring 234 is fixedly connected to the upper side of the slide seat 232, and the upper end of the return spring 234 is fixedly connected to the upper inner wall of the activity cavity. The staff can pull down the clamping block 233, and the slide seat 232 can be slightly moved down in the activity cavity under the premise that the connection seat 231 remains stationary, and the return spring 234 is in a stretched state.

[0037] See also Figures 5 - 9 , the left and right sides of the connecting seat 231 are provided with a slide groove 2, and the sides of the two corresponding slide grooves 2 on the left and right that are close to each other are provided with a slide hole connected to the corresponding active cavity, the locking component 24 includes two iron slide plates 241, the slide plate 241 is slidably connected with the corresponding slide groove 2, and the sides of the left and right corresponding slide plates 241 that are close to each other are fixedly provided with a limit pin 242, and the limit pin 242 is slidably connected with the corresponding slide hole, and the left and right sides of the slide seat 232 are provided with a limit groove matching the limit pin 242, and the front and rear sides of the slide plate 241 are fixedly provided with guide columns 243 symmetrically arranged up and down through the ear seat 1, and the front and rear sides of the connecting seat 231 are fixedly provided with four ear seats 2 distributed in a matrix, and the guide columns 243 are movably plugged with the corresponding ear seats 2, and the surface of the guide columns 243 is sleeved with a return spring 244, and the two ends of the return spring 244 are respectively fixedly connected to one side of the ear seat and the surface of the guide column 243. The staff pulls the clamping block 233 downward to align the limit groove on the slide 232 with the corresponding limit pin 242. Then, under the action of the second return spring 244 (in a stretched state), the limit pin 242 can be inserted into the limit groove, so that the slide 232 and the clamping block 233 below are locked. At this time, the clamping block 233 no longer moves relative to the connecting seat 231. Then, by rotating the clamping screw 222, the clamping block 233 can be moved downward to fix the reducer shaft.

[0038] See also Figure 6 and Figure 7 A plurality of guide balls 6 are rotatably arranged on the surface of the stop pin 242 and the stop slot inserting section, and 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 with the inner wall of the stop slot, so that the stop pin 242 can limit the vertical direction of the slide seat 232 while reducing the friction between the stop pin 242 and the stop slot when sliding horizontally.

[0039] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10The unlocking assembly 25 includes two guide frames 251 fixedly arranged 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 with 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 arranged 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 plate 241 on the moving path, driving the slide plate 241 to slide outward so that the limit pin 242 slides out of the corresponding limit groove, releasing the lock on the slide seat 232. At this time, the slide seat 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 to generate pressure. After the subsequent drilling of the drill rod, the reducer shaft will not be deformed at this position due to the pressure of the clamping block 233.

[0040] See also 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, which flexibly contacts with the corresponding electromagnetic suction cup 255. After the electromagnetic suction cup 255 contacts with the docking plate 256, they can be adsorbed together, so that when the active push rod 254 is reset later, the driven push rod 252 can be pulled to drive the electromagnetic suction plate 253 to reset.

[0041] During 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, and all the clamping blocks 233 are adjusted using the same method.

[0042] Then the staff rotates the adjusting screw 31, so that the lower pressing seat 223 drives the connecting seat 231 to move downward, so that the pressing block 233 below the connecting seat 231 contacts the surface of the reducer shaft to fix the reducer shaft. Multiple pressing blocks 233 are distributed along the length direction of the reducer shaft, and the last pressing block 233 is at the rearmost position of the reducer shaft.

[0043] During drilling, the drilling machine drives the drill rod to move toward the reducer shaft, drills the reducer shaft and gradually goes 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 slide plates 241, so that the slide plate 241 slides outward and drives the limit pin 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, so that the clamping block 233 that originally pressed against the surface of the reducer shaft moves upward and no longer presses 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 finally 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 drilling is stopped after a certain length is reached before the end of the reducer shaft, ensuring that at least one clamping block 233 at the end of the reducer shaft is still pressed 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 processing process of the clamping device and the external drilling device is as follows: the reducer shaft is placed in the V-shaped groove of the clamping seat 1, one end of the reducer shaft contacts the side block 33, and then the staff rotates the clamping screw 222 to make the clamping block 233 move down and contact the surface of the reducer shaft. According to the length of the reducer shaft, multiple clamping mechanisms 2 are provided 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 on the drilling path of the reducer shaft to clamp the same reducer shaft.

[0045] When drilling, the drill rod on the external drilling device is aligned with the reducer shaft and moved to drill. The frontmost clamping block 233 clamps the first section of the reducer shaft to fit the drill rod to drill. When the drill rod approaches the clamping block 233, the clamping block 233 that abuts against the surface of the reducer shaft below releases the lock of the clamping block 233 by the locking assembly 24 through the unlocking assembly 25, so that the clamping block 233 moves up and separates from the reducer shaft. At this time, the clamping block 233 no longer exerts pressure on the surface of the reducer shaft, and the reducer shaft is fixed by the next unlocked clamping block 233. When the drill rod moves to the bottom of the unlocked clamping block 233, the reducer shaft at this position will not be deformed due to the pressure of the clamping block 233 after changing from a solid structure to a hollow structure.

[0046] Subsequently, the same method can be used to drill each section of the subsequent reducer shaft.

[0047] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
