[0026] refer to Figure 1-3 As shown, one embodiment of this utility model is as follows:

[0027] A milling fixture includes a fixed base plate 1, a fixture back plate 2 on the fixed base plate 1, a plurality of fixing holes 3 for fixing workpieces on the fixture back plate 2, a plurality of side top blocks 5 for supporting workpieces 4 on the fixed base plate 1, and a clamping component is detachably and slidably installed on the side of the side top block 5 opposite to the fixture back plate 2 on the fixed base plate 1.

[0028] Specifically Figure 1 The workpiece 4 shown only represents the part connected to the tooling back plate. During clamping, after the workpiece is pre-positioned on the side top block 5, it is pushed close to the tooling back plate 2 by the clamping component, and then fixed to the tooling back plate 2 by screws. The tooling back plate 2, the side top block 5, and the clamping component achieve clamping of the workpiece. The clamping accuracy is high, which is convenient for processing on a three-axis machine tool and reduces production costs.

[0029] Since the workpiece protrudes downwards in some areas, in order to reduce the height of the tooling, a workpiece clearance opening 6 is provided on the fixed base plate 1 on the side of the tooling back plate 2 facing the side top block 5, so as to accommodate the downward protruding part of the workpiece.

[0030] In this embodiment, a limiting groove 7 is provided on the side of the side top block 5 opposite to the tooling back plate 2 on the fixed base plate 1, and an adjusting screw hole 8 is provided on the side wall of the fixed base plate 1. The clamping member includes a push plate 9 adapted to the limiting groove 7, and a connecting plate 10 is provided on the back of the push plate 9. An adjusting screw 11 adapted to the adjusting screw hole 8 is rotatably connected to the end of the connecting plate 10 away from the push plate 9.

[0031] The adjusting screw 11 is provided with a limiting plate located between the threaded part 1101 and the operating part 1102, and the connecting plate 10 is rotatably connected to the adjusting screw 11 between the two limiting plates.

[0032] The end opening of the limiting slide 7 extends to the side wall of the fixed base plate 1.

[0033] By adjusting the screw 11 to screw in / out in the adjusting screw hole 8, the push plate 9 can slide on the limiting slide groove 7, which is simple and convenient to operate.

[0034] In this embodiment, the fixed base plate 1 is provided with an installation positioning groove adapted to the tooling back plate 2, the lower end of the tooling back plate 2 is provided with an insertion part 201 adapted to the installation positioning groove, the lower end of the insertion part 201 is provided with a positioning hole 202, and the installation positioning groove is provided with a positioning block adapted to the positioning hole 202.

[0035] To improve the welding accuracy between the tooling back plate 2 and the fixed base plate 1, during the insertion of the insertion part 201 into the installation positioning groove, the positioning block cooperates with the positioning hole 202 to achieve pre-fixation of the tooling back plate 2 and the fixed base plate 1, thereby ensuring the welding accuracy of the two.

[0036] Furthermore, since the workpiece is fixed to one side of the tooling back plate 2, the tooling back plate 2 bears a large load. Therefore, the fixed base plate 1 is provided with a plurality of support plates 12 adapted to the tooling back plate 2, and the support plates 12 are located on the side of the tooling back plate 2 away from the side top block 5.

[0037] Furthermore, to facilitate the installation and fixing of the base plate 1 to the machine tool, multiple slots 13 for bolts to pass through are provided on both sides of the base plate 1.

[0038] The tooling back plate 2 is equipped with a tool inspection table 14. The tool inspection table 14 is used to verify the machining tools and trajectories to ensure machining quality.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
