[0002] The electric power steering system (EPS) is a power steering system that directly relies on the motor to provide auxiliary torque. The main structure of the automotive electric power steering motor is assembled from a drive motor and a gearbox, which has a deceleration function; the drive motor provides high-speed and low-torque speed output, and the gearbox is connected to the drive motor to reduce the high-speed speed output by the drive motor and increase the torque to achieve an ideal transmission effect. The motor end cover is one of the main components of the drive motor. Its function is to determine the spatial position of the rotor shaft. When it needs to cooperate with different forms of bearings, it is connected to the housing of the fixed motor stator through the end cover to ensure the gap between the rotor and the stator. The existing motor end cover uses a turning and milling composite equipment, which leads to high processing costs, and there are risks in the sequence processing of special characteristic dimensions, which affects the processing accuracy. At the same time, the existing fixture can only adapt to one clamping method, and the practicality is poor. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of the utility model is to provide a steering drive motor end cover processing fixture, which can effectively clamp the drive motor end cover to maintain processing, and at the same time can provide another way of side to center clamping and top downward clamping to improve practicality.

[0017] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.
[0018] like Figure 1 and Figure 2 As shown, a steering drive motor end cover processing fixture includes a workbench 1 and a motor end cover 17. A groove 2 is opened on one side of the upper surface of the workbench 1. Two support blocks A3 are symmetrically arranged inside the groove 2. A support block B4 is fixedly arranged inside the groove 2. The two support blocks A3 and the support block B4 are distributed at an angle of 60°. A guide block 5 is arranged on the upper surface of the support block A3. A fixed block 6 is arranged on the surface of the guide block 5. The ends of the upper surfaces of the support blocks A3 and the support blocks B4 that are close to each other are symmetrically arranged with springs through pins. The inner end of the groove 2 is provided with three movable clamping blocks 8, and three cylinders A9 are evenly arranged at the bottom of the workbench 1. The positions of the cylinder A9 and the movable clamping blocks 8 correspond one to one. The end of the movable clamping block 8 is fixed on the output end of the cylinder A9. The motor end cover 17 is placed on the upper surfaces of the support blocks A3 and B4. Three end cover ear plates 18 are evenly arranged on the outer surface of the motor end cover 17. The end cover ear plates 18 correspond to the end positions of the movable clamping blocks 8 respectively, and the end cover ear plates 18 are placed between the two elastic rods 7 in the same group.
[0019] According to the above structure, the fixed block 6 and the guide block 5 on the surface are used to facilitate the installation and positioning of the motor end cover 17. One side of the elastic rod 7 is pulled by the tension spring so that its ends always have a force close to each other, so as to facilitate the initial clamping of the end cover ear plate 18 when it enters to prevent it from being damaged. The three movable clamping blocks 8 are simultaneously moved inward as far as possible to effectively clamp the motor end cover 17 toward the center.
[0020] like Figure 1 and Figure 2 As shown, a cylinder B11 is arranged on the other side of the upper surface of the workbench 1, a pressure plate 14 is arranged laterally on the side of the output end of the cylinder B11 close to the groove 2, a rubber pressure head 15 is arranged at the bottom of the pressure plate 14, a connecting plate 16 is arranged on the top of the rubber pressure head 15, a connecting shaft penetrating the pressure plate 14 is arranged between the rubber pressure head 15 and the connecting plate 16, the connecting plate 16 is installed on the upper surface of the pressure plate 14 by bolts, a rotating seat 10 is installed on one side of the upper surface of the workbench 1 through a bearing, the rubber pressure head 15 is placed directly above the rotating seat 10, the motor end cover 17 is placed between the rotating seat 10 and the rubber pressure head 15, a bracket 12 is arranged on the lower surface of the workbench 1, a rotating motor 13 is installed on the inner side of the bracket 12, and the output end of the rotating motor 13 is coaxially connected to the rotating seat 10.
[0021] According to the above structure, the rubber pressure head 15 can prevent the pressure under the pressure plate 14 from being too large and causing damage to the surface of the motor end cover 17. When the rubber pressure head 15 is lifted, the motor end cover 17 can be driven to rotate by the rotating motor 13 at the bottom to adjust its angle, which is convenient for processing and improves practicality during use.
[0022] The working principle of the utility model is as follows: the motor end cover 17 is placed at the center position of the groove 2, and then the end cover ear plate 18 is placed below the end of the movable clamping block 8, and the end cover ear plate 18 is placed between the two elastic rods 7 to obtain a preliminary angle fixation to prevent rotation, and the end cover ear plate 18 is supported by the support block A3 and the support block B4, and the cylinder A9 at the bottom is controlled to drive the movable clamping block 8 at the top to clamp and fix the end cover ear plate 18, so that the motor end cover 17 is fixed as a whole. At this time, the top of the motor end cover 17 is exposed to facilitate processing. The motor end cover 17 can also be fixed at the top center, and the motor end cover 17 is installed on the top of the rotating seat 10. The cylinder B11 controls the pressing plate 14 to move downward, and then the rubber pressure head 15 presses down the top of the motor end cover 17 to achieve fixation. The rotating seat 10 can also be controlled to rotate by the rotating motor 13 at the bottom, and then the angle of the motor end cover 17 installed on the top is controlled to improve the flexibility of the processing room.
[0023] The above is only a preferred embodiment of the present invention.
