Description

Technical Field

[0001] This utility model relates to the field of metal material processing technology, and in particular to a clamping device for machining the end face of a motor shaft. Background Technology

[0002] The motor shaft is a supporting component for the motor rotor. It is connected to the stator of the motor via bearings and is used to transmit the motor's mechanical energy. The motor shaft is usually a cylindrical metal component, and its shape and size vary depending on the type, power, and application requirements of the motor.

[0003] When machining a motor shaft, its end faces need to be machined to ensure flatness. Sometimes, holes need to be drilled on both end faces of the motor shaft to facilitate effective fixation by the centering device on the lathe. However, current clamping devices cannot effectively fix the motor shaft when its length and dimensions change, affecting subsequent machining efficiency.

[0043] Example

[0044] This embodiment provides a clamping device for machining the end face of a motor shaft, comprising a fixed base 1, two clamping mechanisms, and a drive mechanism.

[0045] Both clamping mechanisms include a support base 2, a support member, two clamping modules, and a drive member; in the two clamping mechanisms, such as Figure 1 As shown, the support seat of any clamping mechanism is fixed at one end of the fixed seat 1, and the other support seat is slidably disposed on the fixed seat 1 along the length direction of the fixed seat 1.

[0046] like Figure 2As shown, the support includes a base plate 4 and a support plate 5; the base plate 4 is fixed in the middle position of the support base; the base plate 4 has a right-angle structure; the vertical part of the base plate 4 is provided with two sets of connecting through holes 6, and each set of connecting through holes 6 is vertically and equally spaced; the support plate 5 is provided with two oblong through holes 7; each oblong through hole 7 is fitted with a bolt 8, and the end of the bolt 8 is fitted with a nut 9; the top of the support plate 5 has a V-shaped support part 10.

[0047] The two clamping modules are slidably mounted on the support base 2 and distributed on both sides of the support member;

[0048] The driving component is used to drive the two clamping modules to move closer to each other or further apart.

[0049] In this embodiment, as Figure 3 As shown, the driving component includes a first lead screw 11 and a first motor 12; the first lead screw 11 is horizontally rotatably mounted on the support base 2 and perpendicular to the length direction of the fixed base 1; the first motor 12 is mounted at one end of the support base 2 and is used to drive the first lead screw 11 to rotate; the bottoms of the two clamping modules are threaded onto the first lead screw, and the internal threads of the sleeved portions are rotated in opposite directions; with this configuration, under the drive of the first motor 12, the first lead screw 11 rotates, and the two clamping modules move closer to each other or further away from each other.

[0050] In this embodiment, as Figure 3 As shown, the clamping module includes a sliding seat 13, a mounting plate 14, and a clamping plate 15. The sliding seat 13 is threaded onto the first lead screw 11. The sliding seat 13 has several grooves 16 along the length of the fixed seat 1. The mounting plate 14 is slidably disposed on the grooves 16 and remains vertical. Each position on the mounting plate 14 opposite the grooves 16 is provided with a set screw 17, which secures the mounting plate 14 to the appropriate position. The clamping plate 15 is fixed to the inner wall of the mounting plate 14. The clamping plate 15 has a clamping part 18 for clamping the motor shaft. This design allows for easy adjustment of the mounting plate's position, better adaptation to the motor shaft, and efficient clamping.

[0051] Furthermore, the inner wall of the clamping part 18 of the clamping plate 15 is provided with anti-slip pads 19, which can better clamp the motor shaft.

[0052] The drive mechanism is used to drive the sliding support plate to move on the fixed seat 1.

[0053] Specifically, in this embodiment, such as Figure 3As shown, the upper surface of the fixed base 1 is provided with a placement groove 20 along its length direction; the driving mechanism includes a second lead screw 21 and a second motor 22; the second lead screw 21 is horizontally rotatably disposed in the placement groove 20; the second motor 22 is used to drive the second lead screw 21 to rotate; the slidingly disposed support plate is threadedly sleeved on the second lead screw 21; with this configuration, under the drive of the second motor 22, the slidingly disposed support plate moves linearly along the direction of the second lead screw 21, adapting to the length of the motor shaft, and better clamping the motor shaft.

[0054] Furthermore, in this embodiment, the fixed seat 1 is provided with guide grooves 23 on both sides of the second lead screw 11, and the support seat threaded onto the second lead screw 21 is slidably disposed on the two guide grooves 23 to effectively guide it and prevent it from deviating.

[0055] like Figure 4 As shown, when the clamping device is in operation, it adjusts the position of the sliding support on the fixed seat 1 by rotating the second lead screw 21 according to the length of the motor shaft to be processed. Then, it adjusts the position of the mounting plates on the two clamping mechanisms on the slide groove 16 to better fit the motor shaft to be processed. The positions of the two support plates 5 on the base plate 4 are adjusted, and then the nuts 9 on the bolts 8 are tightened to fix the support plates 5. The motor shaft to be processed is placed on the V-shaped support parts 10 of the two support plates 4, and the first motor 12 is started. The first lead screw 11 rotates, and the two clamping modules move closer to each other to clamp the side of the motor shaft, making it convenient for the cutting tool on the lathe to process its end face.
