[0029] The base 1 is a rectangular parallelepiped structure, which has the characteristics of high structural stability, high space utilization, simple manufacturing process, easy installation and maintenance, and wide application range. In other embodiments, the base 1 can also be a cube structure, a cylindrical structure, etc.

[0030] There are two limit grooves 111, which are arranged in parallel along the length direction of the base 1. The limit grooves 111 can not only accommodate the reinforcing ribs 3131 on the inner wall of the motor base in the grooves so that the inner wall of the motor base is close to the fixed platform 11, but also limit the lateral movement of the motor base by limiting the lateral movement of the reinforcing ribs 31 on the inner wall of the motor base. The number of limit grooves 111 matches the number of reinforcing ribs 31 on the inner wall of the motor base. In other embodiments, the number of limit grooves 111 can also be 3, 4 or other numbers.

[0031] Please also read Figure 4 A limiting plane 122 is provided on the opposite side of the two limiting protrusions 12 , and the limiting plane 122 is used to limit the horizontal movement of the motor base, specifically to limit the movement of the motor base along the length direction of the base 1 .

[0032] The limiting protrusion 12 also includes a supporting portion 123 and a first avoiding portion 124. The vertical height of the supporting portion 123 is greater than the vertical height of the first avoiding portion 124. The locking hole 121 is provided in the first avoiding portion 124. The supporting portion 123 is used to support the pressing plate 2. The avoiding portion is used to provide space for the pressing plate 2 to bend and deform. After the screw nut abuts against the pressing plate 2, the screw continues to be screwed into the locking hole 121. The screw nut continues to press the pressing plate 2 downward. The pressing plate 2 bends and deforms toward the first avoiding portion 124, and the motor base is pressed against the fixed platform 11. The limiting plane 122 is located on the side of the first avoiding portion 124 facing the base 1. The number of the locking holes 121 is 3, which are symmetrically arranged at equal intervals along the width direction of the base 1 to further improve the locking stability. The number of the through holes 211 corresponds to the locking holes 121. In other embodiments, the number of the locking holes 121 may be 2, 4 or other numbers. The locking holes 121 may also be arranged in a triangle or in a square array.

[0033] Please also read Figure 3 The base 1 is also provided with a fixing hole for fixing it on a processing machine, and the assembly hole 13 vertically penetrates the base 1. Insert a bolt into the assembly hole 13, the bolt head abuts against the top of the base 1, and the tail of the bolt passes through the fixing hole of the processing machine and is locked by a nut, so that the base 1 is fixed to the processing machine together, and the operation is simple. In another embodiment, the base 1 can also be clamped on the machine through a buckle structure, or a threaded column is provided at the bottom of the base 1, and the threaded column is inserted into the fixing hole of the processing machine and locked by a nut.

[0034] The assembly hole 13 is provided on the fixing platform 11. The fixing platform 11 is located in the middle of the base 1. The fixing platform 11 is provided with the assembly hole 13 to fix the base 1 more stably. In addition, the fixing platform 11 has a simple structure, a larger area, and a larger utilization space, and it is more convenient to set a plurality of the assembly holes 13 to further enhance the fixing effect. In another embodiment, the assembly hole 13 can also be provided on the limiting protrusion 12.

[0035] The number of the assembly holes 13 is 2, which are symmetrically arranged at both ends of the fixed platform 11. The symmetrical distribution of the assembly holes 13 can make the stress borne by each assembly hole 13 relatively balanced, avoiding material fatigue or damage caused by local stress concentration, thereby improving the strength and stability of the overall structure. In other embodiments, the number of the assembly holes 13 can also be 3, 4 or other numbers.

[0036] The assembly hole 13 is a countersunk hole, which can prevent the inserted screw nut or bolt head from protruding from the fixing platform 11 and interfering with the assembly of the motor base. In addition, through the countersunk hole process, the screw nut or bolt nut can be more firmly fixed on the base 1, increasing the connection strength.

[0037] Please also read Figure 5 The intersection of the sides and the top of the base 1 is also provided with a second avoidance portion 14 to prevent interference with the corner of the motor base, so as to facilitate the assembly of the motor base on the base 1. The cross section of the second avoidance portion 14 is L-shaped, which can provide sufficient space to avoid the motor base. In another embodiment, the intersection of the sides and the top of the base 1 can also be chamfered or rounded to avoid the motor base.

[0038] The clamping portion 22 is provided with an avoidance groove 221 to prevent interference with the connecting ribs 32 of the motor base. The opening of the avoidance groove 221 is horizontally oriented toward the middle of the base 1, which facilitates the insertion of the clamping plate 2 into the through-hole of the motor base and better clamps the motor base. The number of the avoidance grooves 221 is 2, which matches the number of connecting ribs 32 of the motor base that need to be avoided. In other embodiments, the number of the avoidance grooves 221 can also be 1, 3 or other numbers, matching the connecting ribs 32 of the motor base.

[0039] The aperture of the through hole 211 is greater than or equal to the aperture of the locking hole 121 to prevent the aperture of the through hole 211 from being too small, which would result in the screw being unable to pass through the through hole 211 and be threadedly connected to the locking hole 121 .

[0040] The specific examples described above further illustrate the purpose, technical solutions and beneficial effects of the present application in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
