[0020] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example

[0022] Please see Figure 1-6 As shown in the figure, this embodiment discloses a machining fixture for drilling oil holes in gears, including a support base 1, a fixture base 2, an adjusting plate 3, a connecting member 4, an adjusting member, and a support member 5. The support base 1 is placed on a drilling machine base and fixed to the base via multiple through holes 10 on its top to prevent movement. The fixture base 2 is inclined to the top of the support base 1. An adjusting plate 3 is provided on the side of each fixture base 2 facing the support base 1 at an obtuse angle. Each adjusting plate 3 is rotatably connected to the support base 1 via a connecting member 4. A support member 5 is provided on the outer wall of each adjusting plate 3. The fixture base 2 supports the adjusting plate 3, the adjusting plate 3 holds the gear workpiece 8, and the support member 5 supports the gear workpiece 8 placed on the adjusting plate 3. An adjusting member is installed within an adjusting hole 20 on the fixture base 2. This adjusting member can rotate the adjusting plate 3, thereby adjusting its angle to accommodate drilling oil holes at different angles in the gear.

[0023] Specifically, in this embodiment, the support base 1 is a rectangular steel plate with a certain thickness. Four through holes 10 are opened on the top of the support base 1, distributed around its perimeter. When the support base 1 is placed on the drilling machine base, a T-block is inserted into the drilling machine base through a hole in the table surface. A screw 22, rotatably connected to the T-block, is installed inside the through hole 10 of the support base 1, thereby fixing the support base 1 to the drilling machine base surface. Two tooling bases 2 are selected, each with two adjustment holes 20 inside. Both tooling bases 2 are inclined on the top of the support base 1. It should be noted that the acute angle between each tooling base 2 and the support base 1 is 50°. The two adjustment holes 20 inside each tooling base 2 are located on the side of the tooling base 2 away from the support base 1. An adjustment component is installed inside each adjustment hole 20, which can move back and forth along the central axis of the adjustment hole 20, thereby pushing the adjustment plate 3 on the tooling base 2. Furthermore, in this embodiment, the two inclined tooling bases 2 and the support base 1 form an isosceles triangular structure. This optimizes the space occupied by the tooling while increasing processing efficiency by simultaneously processing gear workpieces 8, and facilitates the drilling of oil holes in the gear workpieces 8 by the drilling machine base. An adjusting plate 3 is provided on the outer wall of each tooling base 2 facing the side forming an obtuse angle with the support base 1. A connecting piece 4 is provided on the side of each adjusting plate 3 near the support base 1, connecting each adjusting plate 3 to the support base 1. This allows the adjusting plate 3 to rotate on the top of the support base 1, and under the action of the adjusting piece, the adjusting plate 3 is pushed to rotate on the support base 1 to adjust its angle, thereby satisfying the processing of oil holes at different angles in the gear. It is important to note that when each adjusting plate 3 rotates to contact the adjacent tooling base 2 via the connecting piece 4, there is no gap between the contact surfaces of each adjusting plate 3 and the adjacent tooling base 2. This means the adjusting plate 3 can completely fit against the tooling base 2, increasing the support area of ​​the tooling base 2 on the adjusting plate 3. This prevents the gear workpiece 8 from squeezing the adjusting plate 3 during processing, thus avoiding bending of the adjusting plate 3 or affecting the use of the connecting piece 4. Furthermore, in this embodiment, when the adjusting plate 3 rotates, the acute angle between the adjusting plate 3 and the support base 1 varies from 50° to 70°. A support piece 5 is provided on the outer wall of each adjusting plate 3 facing itself at an obtuse angle to the support base 1. The support piece 5 is located on the outer wall of the adjusting plate 3 closest to the support base 1. When the gear workpiece 8 is placed on the adjusting plate 3, it can be supported by the support piece 5, preventing the gear workpiece 8 from falling off the adjusting plate 3.

[0024] Furthermore, in this embodiment, the connecting member 4 is a heavy-duty hinge, the adjusting member is an adjusting bolt, and the supporting member 5 is a supporting block 7. The heavy-duty hinge has the advantages of high stability, good safety, and low cost. The adjusting bolt is rotatably connected to the tooling base 2 through the adjusting hole 20. The end face of the adjusting bolt facing the obtuse angle formed between the tooling base 2 and the supporting base 1 contacts the adjusting plate 3. That is, by rotating the adjusting bolt, the adjusting bolt can move back and forth along the central axis of the adjusting hole 20, thereby realizing the angle adjustment of the adjusting plate 3. The supporting block 7 is a steel block with a V-shaped inclined surface on the top. When the gear workpiece 8 is placed on the adjusting plate 3, the gear workpiece 8 contacts the V-shaped inclined surface on the top of the supporting block 7. The V-shaped inclined surface can prevent the gear workpiece 8 from rolling to both sides, thereby improving the stability of the gear workpiece 8 on the adjusting plate 3.

[0025] Furthermore, each tooling base 2 has a screw hole 21 inside. Specifically, the screw hole 21 is located near the middle of the tooling base 2. A screw 22 is installed inside the screw hole 21. A pressure plate 24 is fitted on the outer wall of the screw 22 facing the obtuse angle formed between the tooling base 2 and the support base 1. Two nuts 23 are threaded onto the outer wall of the screw 22. The two nuts 23 are located on both sides of the pressure plate 24. One nut 23 contacts the side of the tooling base 2 away from the adjusting plate 3, and the other nut 23 contacts the side of the pressure plate 24 away from the tooling base 2. When the gear workpiece 8 is placed on the adjusting plate 3, the screw 22 is passed through the hollowed-out part in the middle of the gear workpiece 8, that is, into the shaft hole of the gear workpiece 8. To prevent the gear workpiece 8 from falling off the adjusting plate 3, the nuts 23 on the outer wall of the screw 22 are rotated so that the pressure plate 24 is tightly attached to the surface of the gear workpiece 8, thereby completing the position limitation of the gear workpiece 8. It should be noted that the adjusting plate 3 has a U-shaped hole 30 at its center, with the opening of the U-shaped hole 30 facing the top of the adjusting plate 3. When the adjusting component on the tooling base 2 drives the adjusting plate 3 to rotate, the screw 22 on the tooling base 2 will not move with the adjusting plate 3. In this case, to prevent the screw 22 from affecting the rotation of the adjusting plate 3, the U-shaped hole 30 is provided on the adjusting plate 3 to provide rotation space for the screw 22. In addition, to prevent the nut 23 from changing from surface contact to line contact when the pressure plate 24 and the screw 22 form a certain angle during the rotation of the adjusting plate 3, a washer is fitted on the outer wall surface of the screw 22 between the nut 23 and the pressure plate 24. This allows the nut 23 to press the pressure plate 24 by squeezing the washer, thus avoiding the line contact between the nut 23 and the pressure plate 24 and affecting the service life of the pressure plate 24.

[0026] The top of the aforementioned support base 1 is provided with multiple support steel plates, all located on one side of the acute angle formed between the tooling base 2 and the support base 1. Each support steel plate serves to support the tooling base 2. Specifically, in this embodiment, there are seven support steel plates: four are located between the top of the support base 1 and the tooling base 2, one is located in the middle of the support base 1 and the middle of the tooling base 2, and the remaining two are located between the upper outer walls of adjacent tooling bases 2. The four support steel plates located between the support base 1 and the tooling base 2 are trapezoidal, and each support steel plate connects the support base 1 and one of the tooling bases 2, providing support to the bottom of the tooling base 2. One hexagonal support steel plate, located in the middle of both the support base 1 and the tooling base 2, connects to both the support base 1 and the two tooling bases 2. The connection point between the support steel plate and the support base 1 is located in the middle of the support base 1, and the connection point between the support steel plate and the two tooling bases 2 is located in the middle of the two tooling bases 2. This support steel plate provides support for the middle sections of the two tooling bases 2. The remaining two support steel plates are trapezoidal and connect to two adjacent tooling bases 2 respectively. The connection points between these two support steel plates and the adjacent tooling bases 2 are located on the upper outer wall of the tooling bases 2, providing support for the upper part of the tooling bases 2. The arrangement of multiple support steel plates prevents instability in the support of the tooling bases 2 during the drilling of oil holes in the gear workpiece 8, which could affect the machining quality of the gear workpiece 8.

Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other.
