Description

Technical fields:

[0001] This utility model relates to the technical field of workpiece processing fixtures, and more specifically to a milling device for magnesium alloy parts. Background technology:

[0002] Magnesium alloy parts are cast, but the casting process only produces a rough blank. This blank then needs to be machined to obtain the finished product, such as a magnesium alloy car dashboard bracket. Figure 1 As shown, the process requires milling. During milling, the car dashboard bracket needs to be mounted on a clamping base plate. Multiple hydraulic clamps are used to clamp and fix it to the clamping base plate. Some car dashboard brackets have frames for installation, and the frames have a certain installation angle. Different car dashboard brackets have frames with different installation angles. Although hydraulic clamps with the same angle can be used for clamping and limiting, the clamping parts on the frame are lines or points, not surfaces, which can easily lead to indentations or dents on the frame. Therefore, it is necessary to design a structure with adjustable hydraulic clamp angles. Utility model content:

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a milling device for magnesium alloy parts. It modifies the base of the clamping plate with hydraulic clamps, enabling the adjustment of the angle of the hydraulic clamps. This allows the hydraulic clamps to press against the frame of the car dashboard bracket in a surface contact manner, resulting in a stable clamping and less likelihood of indentations.

[0018] Example: See Figures 1 to 3 As shown, a milling device for magnesium alloy parts includes a clamping base plate 1 for milling. Two sets of magnesium alloy workpieces 6 are arranged on the upper side of the clamping base plate 1. One side of each magnesium alloy workpiece 6 is inclined and rests against a support 2, which is fixed to the clamping base plate 1. Several sets of hydraulic clamps 4 are arranged around the magnesium alloy workpiece 6, and the hydraulic clamps 4 are fixed to the support 2 and the clamping base plate 1. An inclined mounting side plate 61 is formed on one side of the magnesium alloy workpiece 6. A recess 11 is formed on the clamping base plate 1 below the mounting side plate 61. A pad 3 is inserted into the recess 11. The upper end face of the pad 3 is inclined and fixed to a hydraulic clamp 4. The chuck of the hydraulic clamp 4 presses against the mounting side plate 61. The bottom surface of the recessed platform 11 is formed with an arc-shaped groove 12 that penetrates the lower end face of the clamping base plate 1. An adjustment base 7 with a semi-circular cross-section is inserted into the groove 12. The lower end of the pad block 3 is fixed to the upper end face of the adjustment base 7. The hydraulic clamp 4 is a conventional hydraulic clamp, which includes a hydraulic base. A vertical piston rod is provided in the hydraulic base. The upper end of the piston rod extends out of the hydraulic base and is hinged to an arc-shaped chuck by a pin. The middle part of the chuck is hinged to a connecting rod by a pin. The lower end of the connecting rod is hinged to an ear seat by a pin. The ear seat is fixed to the hydraulic base. When the piston rod on the hydraulic clamp 4 is pushed out, it can drive the chuck to flip, so that the head of the chuck can press against the magnesium alloy workpiece 6.

[0019] The bottom of the adjusting base 7 extends out of the groove 12 and is formed with a cylindrical connecting post 71. The lower end surface of the connecting post 71 is formed with a slot 72 that penetrates the outer walls of the left and right sides of the connecting post 71. The front and rear side walls of the slot 72 are respectively formed with vertical guide grooves 73. A cylindrical slider 8 is inserted into the guide groove 73. The middle part of the slider 8 is screwed onto the horizontal adjusting stud 9. Positioning plates 10 are respectively fixed to the lower end surface of the clamping base plate 1 on both sides of the groove 12. The adjusting stud 9 is inserted into the slot 72 of the connecting post 71 and pivotally connected to the positioning plate 10.

[0020] A locking block 30 is inserted into the guide groove 73 of the connecting post 71 on the lower side of the slider 8. The upper end of the locking block 30 abuts against the slider 8, and the lower end extends out of the connecting post 71 and abuts against the locking nut 40. The locking nut 40 is screwed and fixed to the lower end of the connecting post 71.

[0021] Several support columns 5 are fixedly connected to the adjusting base 7, the auxiliary clamping base 3, and the clamping base plate 1. The upper ends of the support columns 5 abut against the lower surface of the magnesium alloy workpiece 6. The top of the support column 5 on the adjusting base 7 is spherical. Because there are many grooves or protrusions on the magnesium alloy workpiece 6, its lower surface is not flat. The support column 5 is used for support. The head of the support column 5 on the adjusting base 7 is spherical. When the adjusting base 7 is rotated for adjustment, its support column 5 can support the mounting side plate 61 of the magnesium alloy workpiece 6 at various tilt angles.

[0022] The radius of the arc of the bottom surface of the groove 12 on the clamping base plate 1 is equal to the radius of the arc of the lower surface of the adjusting base 7. The upper part of the adjusting base 7 extends out of the groove 12 and is located in the recess 11 of the clamping base plate 1. When the adjusting base 7 is rotated for adjustment, interference between the hydraulic clamp 4 and the groove 12 can be avoided.

[0023] The upper part of the positioning plate 10 is fixedly connected to a triangular rib plate 60, which is fixedly connected to the lower end face of the clamping base plate 1. The adjusting stud 9 is located below the rib plate 60 and inserted into the positioning plate 10. The head of the adjusting stud 9 abuts against the positioning plate 10 on one side of the groove 12, and the end extends out of the positioning plate 10 on the other side of the groove 12 and is fitted with a limiting sleeve 20. The limiting sleeve 20 abuts against the positioning plate 10. That is, the adjusting stud 9 and the positioning plate 10 are pivotally connected, and the positioning plate 10 can only rotate radially.

[0024] The diameter of the slider 8 is equal to the width of the guide groove 73 on the connecting post 71, and the diameter of the adjusting stud 9 is not less than the opening of the slot 72, thereby improving the fit accuracy.

[0025] The width of the locking block 30 is equal to the width of the guide groove 73 on the connecting post 71. A T-shaped connecting post 50 is inserted and fixed at the lower end of the locking block 30. The connecting post 50 is inserted on the locking nut 40. The locking block 30 can be pivotally connected to the locking nut 40 through the connecting post 50.

[0026] Working principle: This structure is a milling device for magnesium alloy parts. The device is a clamping structure for machining magnesium alloy workpiece 6. Its technical point is reflected in the structure of the hydraulic clamp 4 part of the mounting plate 61 for clamping magnesium alloy workpiece 6.

[0027] Because different magnesium alloy workpieces 6 have mounting plates 61 with different tilt angles, in order to achieve end-face contact of the hydraulic clamp 4 on the upper surface of the mounting plate 61, the angle of the hydraulic clamp 4 needs to be adjusted. Therefore, its adjustment base 7 is modified to be semi-circular, and a connecting post 71 is provided at the bottom. By rotating the adjusting stud 9, the slider 8 can be driven to move on the adjusting stud 9. While the slider 8 is moving on the adjusting stud 9, it will also move in the guide groove 73 of the connecting post 71, thereby changing the setting angle of the connecting post 71. As a result, the position of the adjustment base 7 changes, and thus the hydraulic clamp 4 also changes. In order to prevent the adjustment base 7 from moving upward and disengaging, the adjustment base 7 can be fixed by tightening the locking sleeve 40.

Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
