Description

Technical Field

[0001] The utility model relates to a special boring and milling machine fixture used in a five-axis machining center. Background Art

[0002] With the progress of technology and the update and iteration of products, parts with various complex multi-axis cross-hole systems often appear. The part structure is shown Figures 1 - 3 as follows.

[0003] For special fixture parts, it is very difficult to ensure the design technical requirements for machining on a four-axis or three-axis linkage machining center. Therefore, for the machining of parts with multi-axis cross-hole systems, a five-axis linkage machining center is generally used. Affected by conventional design ideas (clamping, tool feed mode, and positioning structure mode), it is very difficult to meet the requirement of one-time clamping machining for multi-axis cross-hole systems. Since parts with multi-axis cross-hole system structures have high additional economic value and large market demand, designing a fixture that meets the requirement of one-time clamping machining for multi-axis cross-hole systems is an urgent problem to be solved. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides a special boring and milling machine fixture used in a five-axis machining center, which has a simple structure and reliable operation.

[0005] The technical solution of the utility model to solve the above technical problems is: a special boring and milling machine fixture used in a five-axis machining center, including a fixture body. The fixture body includes a horizontally arranged bottom plate and a vertically arranged mounting plate at the middle position of the bottom plate. A first through hole and a second through hole are respectively opened at the front and back of the upper part of the mounting plate. A positioning block is arranged below the first through hole, and a positioning pin is arranged in front of the first through hole. The positioning block and the positioning pin are both fixed on the mounting plate. A first pressing plate is arranged on the right side of the second through hole. The first pressing plate is installed on the bottom plate through a first adjusting bolt. A first adjustable positioning bolt is arranged below the first pressing plate, and the first adjustable positioning bolt is installed on the bottom plate. A second pressing plate is arranged on the left side of the second through hole. The second pressing plate is installed on the bottom plate through a second adjusting bolt. A second adjustable positioning bolt is arranged below the second pressing plate, and the second adjustable positioning bolt is installed on the bottom plate.

[0006] For the above special boring and milling machine fixture used in a five-axis machining center, the positioning block is horizontally arranged and parallel to the bottom plate.

[0007] For the above special boring and milling machine fixture used in a five-axis machining center, the whole fixture body is in an inverted T shape.

[0008] For the above special boring and milling machine fixture used in a five-axis machining center, reinforcing ribs are arranged on both the left and right sides of the lower part of the mounting plate.

[0009] The beneficial effects of the present utility model are as follows: The present utility model is mainly used in the machining of parts with complex multi-axis holes and relatively high dimensional and geometric tolerances. It can solve the problem that multi-axis holes require multiple clampings and are difficult to correct the position, and can realize the simultaneous machining of multi-axis holes in one clamping, thus solving the technical problems in the machining industry.

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] As shown in Figures 3 - 5As shown in the figure, a special boring and milling machine fixture used in a five-axis machining center includes a fixture body. The fixture body includes a horizontally arranged bottom plate 1 and a vertically arranged mounting plate 2 at the middle position of the bottom plate 1. The fixture body is in an inverted T shape as a whole. A first through hole 3 and a second through hole 4 are respectively formed in the front and rear of the upper part of the mounting plate 2. A positioning block 5 is arranged below the first through hole 3. The positioning block 5 is horizontally arranged and parallel to the bottom plate 1. A positioning pin 6 is arranged in front of the first through hole 3. Both the positioning block 5 and the positioning pin 6 are fixed on the mounting plate 2. A first pressing plate 7 is arranged on the right side of the second through hole 4. The first pressing plate 7 is installed on the bottom plate 1 through a first adjusting bolt 8. A first adjustable positioning bolt 9 is arranged below the first pressing plate 7. The first adjustable positioning bolt 9 is installed on the bottom plate 1. A second pressing plate 10 is arranged on the left side of the second through hole 4. The second pressing plate 10 is installed on the bottom plate 1 through a second adjusting bolt 11. A second adjustable positioning bolt 12 is arranged below the second pressing plate 10. The second adjustable positioning bolt 12 is installed on the bottom plate 1. Reinforcing ribs 13 are arranged on both the left and right sides of the lower part of the mounting plate 2.

[0021] As Figures 6 - 9 shown in the figure, one side of the square edge of the part 14 is placed on the positioning block 5 as a reference to limit the Z-axis position, and the Y-axis position is limited by the positioning pin 6. The cylindrical head of the part 14 is placed on the first adjustable positioning bolt 9. One side of the square head of the part 14 passes through the second through hole 4 and is placed on the second adjustable positioning bolt 12. By adjusting the heights of the first adjustable positioning bolt 9 and the second adjustable positioning bolt 12, the X1 axis is parallel to the bottom surface of the fixture and plays an auxiliary supporting role, and the X-axis position is limited. After complete positioning, the part 14 is fixed with the first pressing plate 7 and the second pressing plate 10 to ensure safety and reliability during the machining process. The fixture of the present utility model makes way for the holes of the X1 axis, X2 axis, X3 axis and Z axis, so as to facilitate the tool indexing and feeding of the five-axis linkage machining center. The holes of the 4-axis system can be machined in one clamping, and the dimensional and positional accuracy requirements of the X1 axis, X2 axis, X3 axis and Z axis holes can be fully guaranteed. The fixture has a reasonable structure, a simple manufacturing process, and its practicability and reliability have been verified, and it has innovation and reference value for the design of similar fixtures.
