[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below with reference to the accompanying drawings, but the present application is not limited to the specific embodiments disclosed below.

[0032] like Figure 1-5 The vertical four-axis machining fixture of the present invention includes a mounting mechanism 1 assembled with a machine tool, a machining base 2 is provided on the mounting mechanism 1, and two clamping and positioning modules 3 for fixing the workpieces A to be machined are provided on the machining base 2. The two clamping and positioning modules 3 can fix two workpieces A to be machined at a time and process the two workpieces A to be machined at the same time;

[0033] The clamping and positioning module 3 includes:

[0034] Two main pressing heads 31 are arranged outside the processing base 2.

[0035] Two main pressing heads 31 are provided inside the processing base.

[0036] A hard support head 33 is provided below the main pressure head and the auxiliary pressure head.

[0037] The main pressing head 31, the auxiliary pressing head 32 and the hard supporting head 33 play the main role in clamping the workpiece A.

[0038] An auxiliary support head 34 is provided between the two horizontal hard support heads. The auxiliary support head 34 is located approximately in the middle of one side of the workpiece A to be processed, and plays the role of supporting the middle part of the workpiece A to be processed.

[0039] A left-right centering mechanism 35 is provided between the two longitudinal rigid support heads. The left-right centering mechanism 35 mainly serves to center the workpiece A when it is assembled into the fixture, thereby improving the machining accuracy.

[0040] The left-right centering mechanism 35 includes two telescopic rods 351 and a driving unit 352 of the telescopic rods 351. The driving unit 352 drives the two telescopic rods 351 to move telescopically to the left and right.

[0041] like Figure 4 、 Figure 5 As shown, the driving portion 352 is provided with a symmetrical first bevel portion 353, and the two telescopic rods 351 are provided with a second bevel portion 354 that matches the first bevel portion 353. The first bevel portion 353 and the second bevel portion 354 cooperate with each other to convert the up and down movement of the driving portion 352 into the left and right telescopic movement of the two telescopic rods 351.

[0042] The two telescopic rods 351 are installed on the processing base 2 through the mounting part 36. The mounting part 36 is also provided with a support part 37 for the workpiece A to be processed. The support part 37 is also provided with a first inclined block part 371 and a second inclined block part 372. The design of the first inclined block part 371 and the second inclined block part 372 enables the workpiece A to be processed to slide more smoothly into the clamping and positioning module 3.

[0043] like Figure 3 The vertical four-axis machining fixture also includes an oblique auxiliary positioning head 4. The oblique auxiliary positioning head 4 supports the inner wall of the workpiece A to be machined, so that the workpiece A to be machined has a more precise front and rear position on the machining station, which can further ensure the machining accuracy.

[0044] The main pressure head 31 , the auxiliary pressure head 32 , the oblique auxiliary position-correcting head 4 , and the support portion 37 are all cylinder structures.

[0045] Working principle:

[0046] The two workpieces A to be processed are respectively placed on the two clamping and positioning modules 3 of the vertical machining four-axis fixture described in the present invention. The workpieces A to be processed slide into the clamping and positioning module 3 under the action of the first inclined block part 371 and the second inclined block part 372. At this time, the two telescopic rods 351 on the left and right centering mechanism 35 are extended under the action of the driving part 352, so that the two workpieces A to be processed are centered on the left and right of the clamping and positioning module 3. The auxiliary positioning head 4 is also extended to support the inner wall of the workpiece A to be processed so that its front and rear position is accurate. The two main pressure heads 31, the two main pressure heads 31 press down and the bottom hard support head 33 cooperate to clamp the workpiece A to be processed. The middle auxiliary support head 34 prevents the workpiece A to be processed from being pressed down and deformed during the machining process, thereby improving the product qualification rate.
