[0018] like Figure 1-2 As shown, a clamping and positioning tool for motor cover processing includes a base plate 1, on which a positioning seat 2 for positioning the motor cover workpiece is arranged, and the positioning seat 2 is arranged on the base plate 1 in an array with the center of the motor cover workpiece as the axis, and the positioning seat 2 is provided with a positioning portion 21 corresponding to the outer edge of the motor cover workpiece, so that the positioning portion 21 can be closely attached to the outer edge of the motor seat to ensure positioning accuracy. The positioning seat 2 is provided with a pressing block 3 for pressing the motor cover workpiece, and a pressing hole 31 is provided on the pressing block 3, and a pressing bolt passes through the pressing hole 31 and is screwed to the base plate 1.

[0019] When in use, the substrate 1 is fixed on the processing platform, and the motor cover workpiece is placed on the substrate 1 with the circumferentially arranged positioning seat 2 as a reference, so that the positioning portion 21 of the positioning seat 2 abuts against the outer edge of the motor cover workpiece to complete the positioning of the motor cover workpiece. Then, by tightening the clamping bolt, the pressure block 3 is firmly pressed on the motor seat to complete the positioning and clamping of the workpiece. The outer edge abuts against the motor cover workpiece during use. In this embodiment, the positioning seat 2 is used as the positioning reference of the motor cover workpiece to achieve the positioning and clamping of the motor cover workpiece. During the processing operation, the positioning reference formed by the positioning seat 2 can be reused, eliminating the tedious operations of repeated tool alignment and origin finding in the traditional clamping method, greatly improving the working efficiency.

[0020] As a preferred embodiment, the positioning protrusion on the base plate 1 corresponding to the motor cover workpiece is provided with a positioning groove 11 as a matching positioning structure of the motor housing. When in use, the positioning protrusion on the workpiece just lies in the positioning groove 11, and then is positioned and fixed by the positioning seat 2, further ensuring the positioning accuracy of the workpiece. At the same time, through the cooperation between the positioning protrusion and the positioning groove 11, the radial rotation of the motor cover workpiece during the processing is effectively limited, ensuring the processing quality.

[0021] As a preferred embodiment, the positioning seat 2 is adjustably connected to the base plate 1, so that the position of the positioning seat 2 on the base plate 1 is adjustable, thereby adapting to the positioning and clamping of motor cover workpieces of different sizes. Preferably, an adjustment waist hole 22 is opened on the positioning seat 2, and the adjustment bolt passes through the adjustment waist hole 22 and is screwed on the base plate 1. By adjusting the relative position of the waist hole 22 with respect to the adjustment bolt, the radial size of the circumferentially distributed positioning seat 2 is achieved, thereby satisfying the positioning and clamping of motor cover workpieces of different sizes.

[0022] In a further embodiment, an end face pressing plate 4 is provided on the substrate 1 corresponding to the upper end face of the motor cover workpiece, which is used for clamping and fixing the motor cover workpiece. Preferably, a center column 41 is provided on the substrate 1 in the vertical direction, and a through hole is provided on the end face pressing plate 4 corresponding to the center column 41, and the end face pressing plate 4 is slidably connected to the center column 41 through the through hole. An adjusting nut is screwed to the upper end of the center column 41, which is used to adjust the clamping force of the end face pressing plate 4. This embodiment further ensures the clamping stability of the motor housing by providing the end face pressing plate 4. In addition, in the case where the outer edge of the motor housing needs to be processed, in order to avoid the positioning seat 2 interfering with the tool path, the positioning and clamping of the motor cover workpiece can be achieved only by the end face pressing plate 4, so that the utility model can simultaneously meet the processing of the inner diameter and the outer edge contour of the motor cover workpiece, thereby improving the applicability of the tooling.

[0023] As another embodiment of the clamping and positioning tooling for motor cover processing, the tooling can be split into two special clamping structures including the end face pressure plate 4 and the positioning seat 2, respectively, and the clamping processing of the outer edge and the inner diameter of the motor cover workpiece is performed in sequence through the two clamping structures. In this way, the motor cover workpiece can be processed in a sequenced manner, and the tooling is used for a specific sequence, which is conducive to the positioning and clamping of the workpiece and the guarantee of processing quality.

[0024] The above disclosure is only a specific embodiment of the present patent, but the present patent is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, the deformation made should be deemed to belong to the protection of the present invention.
