[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] In some embodiments, please refer to the accompanying drawings. Figures 1-5 As shown, a device for preventing vibration during machining of magnesium alloy steering base plate opening surface includes a four-axis machining turntable 1, a base plate 2, a multi-point positioning mechanism 3, and an anti-vibration tool support mechanism 4; the movable end of the four-axis machining turntable 1 is fixedly connected to the base plate 2; the four-axis machining turntable 1 adopts mature technology in the industry, such as the four-axis turntable model BrotherSZ.

[0031] A multi-point positioning mechanism 3 is installed at the upper end of the substrate 2 to provide support and limit for the magnesium alloy steering base plate body 5.

[0032] The multi-point positioning mechanism 3 includes a positioning component and multiple sets of clamping components; both the positioning component and the clamping component are mounted on the upper end of the base plate 2;

[0033] The upper front side of the substrate 2 is also equipped with a shock-absorbing blade support mechanism 4 for supporting the opening surface of the magnesium alloy steering base plate body 5.

[0034] The anti-vibration blade support mechanism 4 includes a drive assembly and a movable assembly; two sets of drive assemblies are installed on the upper front side of the base plate 2; the drive assembly is connected to the movable assembly;

[0035] The magnesium alloy steering base plate body 5 has symmetrical positioning holes 51 on its front and rear sides for easy positioning.

[0036] In this invention, the magnesium alloy steering base plate body 5 is placed on the positioning assembly. Subsequently, multiple sets of clamping assemblies work simultaneously to provide clamping force to the magnesium alloy steering base plate body 5, fixing it above the positioning assembly. Then, the driving assembly works to move the movable assembly, so that the movable assembly just contacts the front opening surface of the magnesium alloy steering base plate body 5 without providing clamping force. Then, the magnesium alloy steering base plate body 5 can be processed. During the processing, the movable assembly always provides support to the front opening surface of the magnesium alloy steering base plate body 5, preventing vibration on the opening surface of the magnesium alloy steering base plate body 5.

[0037] The cooperation of the first fixing block 31, the second fixing block 32, the limiting block 33 and the clamping assembly enables the device to quickly position the magnesium alloy steering base plate body 5, reducing the extra time required for positioning and improving processing efficiency. The cooperation of the drive assembly and the moving assembly enables the device to support the front opening surface of the magnesium alloy steering base plate body 5 during processing, avoiding tool vibration and ensuring the processing quality of the magnesium alloy steering base plate body 5.

[0038] like Figure 3 As shown, the positioning component includes a first fixing block 31, a second fixing block 32, a limiting block 33, a limiting pin 34, and a third fixing block 38; the first fixing block 31 is fixedly installed on the upper left side of the substrate 2; the second fixing block 32 is fixedly installed on the upper middle part of the substrate 2; and the third fixing block 38 is symmetrically fixedly installed on the upper right front and rear sides of the substrate 2.

[0039] The limiting blocks 33 are symmetrically fixedly installed on the front and rear sides of the upper middle part of the substrate 2; the upper end of the limiting blocks 33 is fixedly installed with a limiting pin 34 that is inserted into the positioning hole 51.

[0040] like Figure 3As shown, the clamping assembly includes a hydraulic cylinder 35, a contouring block 36, and a supporting rotating block 37; the hydraulic cylinder 35 is fixedly mounted on the upper end of the base plate 2; the output end of the hydraulic cylinder 35 is hinged to one end of the contouring block 36; the lower end of the supporting rotating block 37 is hinged to the upper end housing of the hydraulic cylinder 35; and the upper end of the supporting rotating block 37 is hinged to the middle of the contouring block 36.

[0041] The drive assembly includes an auxiliary support cylinder 41; the auxiliary support cylinder 41 is fixedly installed on the upper end of the base plate 2;

[0042] like Figure 4 As shown, the movable component includes a support base 42, a support plate 43, a support pin 44, a fixing plate 45, and a return spring 46; the support base 42 and the fixing plate 45 are both fixedly installed on the upper end of the base plate 2; the fixing plate 45 is installed in front of the support base 42; the support plate 43 is rotatably installed on the upper end of the support base 42; the support pin 44 is fixedly installed on the rear end of the support plate 43; the upper end of the return spring 46 is fixedly connected to the fixing plate 45; the lower end of the return spring 46 is fixedly connected to the support plate 43.

[0043] In this invention, the positioning hole 51 of the magnesium alloy steering base plate body 5 is aligned with the limiting pin 34 and inserted downwards, so that the magnesium alloy steering base plate body 5 is placed above the first fixing block 31, the second fixing block 32 and the limiting block 33; then the hydraulic cylinders 35 of the multiple clamping components work, and the hydraulic cylinders 35 push the contouring block 36 to rotate upwards. The upward movement of the contouring block 36 will drive the supporting rotating block 37 to rotate upwards. The upward rotation of the supporting rotating block 37 will pull the contouring block 36 to rotate downwards until the contouring block 36 changes from a vertical state to a horizontal state; at this time, the contouring block 36 abuts against the outer end of the magnesium alloy steering base plate body 5, providing clamping force to the magnesium alloy steering base plate body 5, so that the magnesium alloy steering base plate body 5 is fixed above the first fixing block 31, the second fixing block 32 and the limiting block 33;

[0044] Subsequently, the auxiliary support cylinder 41 pushes the support plate 43 upward, causing the support plate 43 to rotate backward around the hinge point with the support seat 42, and the support pin 44 to rotate together. When the support plate 43 rotates, it will also compress the return spring 46 upward until the support pin 44 contacts the front opening surface of the magnesium alloy steering base plate body 5. Then, the magnesium alloy steering base plate body 5 can be processed. After the processing is completed, the auxiliary support cylinder 41 returns to its original position, and at this time, the return spring 46 returns to its original position, which in turn drives the support plate 43 to return to its original position.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
