[0032] like Figures 1-7 As shown, this embodiment proposes a motor spindle spline machining fixing device, including a support plate 10, and mounting plates 60 are provided on both sides of the support plate 10.

[0033] A fixed plate 40 is provided on the mounting plate 60. Two sets of movable plates 30 are provided between the mounting plate 60 and the fixed plate 40. A rubber contact plate 20 is provided on the movable plate 30. A drive assembly 50 is also provided between the mounting plate 60 and the fixed plate 40. The drive assembly 50 cooperates with the two sets of movable plates 30, so that the two sets of movable plates 30 move toward the center of the support plate 10 to clamp the motor spindle.

[0034] In this embodiment, when the motor shaft is spline processed, the motor shaft is placed on the support plate 10, and the driving assembly 50 on the mounting plate 60 works to drive the two groups of moving plates 30 to displace towards the center direction of the support plate 10, so that the rubber contact plates 20 are in contact with the side wall of the motor shaft, and the motor shaft is limited by the clamping of the two groups of rubber contact plates 20;

[0035] By using the clamping structure composed of the support plate 10, the mounting plate 60, the fixed plate 40 and the moving plate 30, and the contact of the rubber contact plate 20 with the side wall of the motor shaft, accurate positioning and clamping of the motor shaft during spline processing are realized, thereby improving the processing precision, allowing the motor shaft to be quickly clamped and released, simplifying the preparation before processing and the cleaning work after processing, thereby improving the overall processing efficiency. At the same time, by adjusting the working state of the driving assembly 50, the device can adapt to motor shafts of different sizes, has good universality and adaptability, and the use of rubber contact plates 20 reduces the direct contact between metals, reduces the wear and damage to the surface of the motor shaft during clamping, and protects the processing surface.

[0036] Specifically, the fixed plate 40 is provided with a fixed protrusion 42, and the mounting plate 60 is provided with a mounting protrusion 61.

[0037] The moving plate 30 is symmetrically provided with two groups of sliding grooves 31, and the fixed protrusion 42 and the mounting protrusion 61 are respectively arranged in the two groups of sliding grooves 31.

[0038] In this embodiment, when the driving assembly 50 drives the moving plate 30 to displace, the fixed protrusion 42 and the mounting protrusion 61 respectively slide in the two groups of sliding grooves 31, thereby effectively ensuring the stability of the displacement of the moving plate 30.

[0039] Specifically, the moving plate 30 is provided with a T-shaped groove 33.

[0040] The rubber contact plate 20 is provided with a T-shaped block 21, the T-shaped block 21 is matched with the T-shaped groove 33, and the T-shaped block 21 is arranged in the T-shaped groove 33, so that the rubber contact plate 20 is connected to the moving plate 30.

[0041] Specifically, the rubber contact plate 20 is provided with a contact hole A23, and the T-shaped groove 33 is provided with a contact hole B34, the contact hole A23 and the contact hole B34 are matched in position and size, and a contact bolt 70 is arranged between the contact hole A23 and the contact hole B34.

[0042] In this embodiment, through the matching structure of the T-shaped groove 33 and the T-shaped block 21, the connection stability between the rubber contact plate 20 and the moving plate 30 is enhanced, and this structure design enables the rubber contact plate 20 to be firmly fixed on the moving plate 30, thereby reducing the displacement or falling phenomenon that may occur during processing.

[0043] Through the matching of the positions and sizes of the contact hole A23 and the contact hole B34, and the use of the contact bolt 70, the relative positions of the rubber contact plate 20 and the moving plate 30 can be accurately positioned, thereby ensuring the accuracy and reliability when clamping the motor main shaft.

[0044] Specifically, the contact hole A23 is provided with a contact groove 22, and the head of the contact bolt 70 is placed in the contact groove 22.

[0045] The head of the contact bolt 70 is provided with an internal hexagonal hole.

[0046] In this embodiment, by placing the contact bolt 70 in the contact groove 22, when the rubber contact plate 20 contacts the surface of the motor main shaft, the contact between the contact bolt 70 and the outer wall of the motor main shaft can be avoided.

[0047] Specifically, the driving assembly 50 includes two groups of driving gears 51, and the two groups of driving gears 51 are rotatably arranged on the mounting plate 60.

[0050] The fixed plate 40 is provided with a servo motor 52, and the servo motor 52 is in transmission connection with the transmission gear 54.

[0051] In this embodiment, when the moving plate 30 needs to be displaced, the servo motor 52 is started to make the transmission gear 54 rotate, so that the adjusting gear 53 rotates, and because the transmission gear 54 is engaged with one group of driving gears 51 and the adjusting gear 53 is engaged with the other group of driving gears 51, the two groups of driving gears 51 simultaneously rotate towards the center direction of the support plate 10, so that the moving plate 30 is displaced towards the center direction of the support plate 10, and when the servo motor 52 drives the transmission gear 54 to rotate in the opposite direction, the two groups of moving plates 30 are simultaneously displaced away from the center direction of the support plate 10.
