Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0020] like Figure 1-4As shown, a tooling fixture for multi-angle machining of fork-shaped parts includes a flipping mechanism 1 and a clamping plate 2. The two ends of the clamping plate 2 are disposed on the flipping mechanism 1, and the clamping plate 2 can be flipped on the flipping mechanism 1.

[0021] The fixture plate 2 is provided with a first process station 3, a second process station 4, a third process station 5 and a fourth process station 6. Each of the first process station 3, the second process station 4, the third process station 5 and the fourth process station 6 is provided with at least three work stations, and each work station is provided with a positioning groove 7 that fits with the fork-shaped part.

[0022] In this embodiment, the fixture plate is provided with four processing stations. The fork-shaped part 8 is processed at different positions and angles at each processing station, and each processing can be carried out simultaneously, which greatly improves processing efficiency and saves fixture costs.

[0023] Each workstation on the first process station 3 is equipped with a first clamping block 31. The center of the first clamping block 31 is fixed to the fixture plate 2 by an adjusting bolt. One end of the first clamping block 31 contacts the push rod, and the other end presses against the fork-shaped part. The push rod is located on the fixture plate 2. After the fork-shaped part 8 is placed in the positioning groove 7, the first clamping block 31 is pressed against the surface of the fork-shaped part 8 by the adjusting bolt, firmly clamping the fork-shaped part 8 onto the fixture plate 2 to ensure machining accuracy.

[0024] Specifically, each station on the second process station 4 is provided with a first waist-shaped blind hole 41. A second pressing block 42 is provided in the first waist-shaped blind hole 41. The second pressing block 42 is set in the first waist-shaped blind hole 41 by adjusting bolts. The structure of the second pressing block 42 is the same as that of the first pressing block 31.

[0025] Specifically, each station on the third process station 5 is provided with a set of second waist-shaped blind holes 51, and each second waist-shaped blind hole 51 is provided with a third pressing block 52. The structure of the third pressing block 52 is the same as that of the first pressing block 31.

[0026] Specifically, each station on the fourth process station 6 is equipped with a support block 61. A positioning groove 7 is located on the side of the support block 61. A clamping bolt 62 is also provided on the support block 61, with a clamping nut at the end of the clamping bolt 62, which is positioned within the positioning groove 7. After the fork-shaped part 8 is placed in the positioning groove 7, the clamping nut is tightened. The clamping nut acts on the surface of the fork-shaped part 8, pressing it firmly against the support block 61.

[0027] Specifically, the flipping mechanism 1 includes rotary tables at both ends, and mounting plates are provided on the rotary tables. The two ends of the clamping plate 2 are fixed to the mounting plates by bolts.

[0028] Specifically, the flipping mechanism 1 is mounted on the worktable of the CNC machining center.

[0029] This utility model provides a tooling fixture for multi-angle machining of fork-shaped parts. In use, three fork-shaped blanks are first clamped at the first processing station 3. Holes are drilled in the workpieces. After drilling, the entire fixture plate 2 rotates 180° with the workpieces. Then, a slot is machined on one side of the workpiece using a CNC machining center. The fork-shaped part 8 is then transferred to the second processing station 4 and clamped using the slot machined at the first processing station 3 and the second clamping block 42. Simultaneously, three blanks are clamped again at the first processing station 3. The surface of the fork-shaped part 8 is milled at the second processing station 4, while drilling is performed at the first processing station. The fixture plate 2 is then rotated again, and a slot is machined on the other side of the fork-shaped part 8. The fork-shaped part 8 is then clamped using the slots machined in the previous two processes and the third clamping block 52. The other side is milled at the third processing station 5 to determine the thickness, and side holes are machined on the side of the fork-shaped part 8. Meanwhile, workpieces to be machined are still clamped at the first two processing stations and are processed simultaneously. Finally, the fork-shaped part 8 is clamped onto the fourth process station 6, and the opening position is precision machined, thus completing all processing steps.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
