[0002] A steel trunnion is a common mechanical part, which is a pivot or arbor installed on a support for rotating or tilting something. When processing a steel trunnion, a milling machine is usually required to perform circular grooving on the outside of the trunnion. However, due to the special shape of the trunnion, when the fixture on the existing milling machine fixes the trunnion, it may cause the trunnion to slide during drilling, resulting in processing failure and reducing the processing speed of the trunnion. At the same time, the drilled area of the trunnion is a hollow structure, which may cause the fixture to squeeze the hollow area when clamping the trunnion, resulting in damage to the trunnion.

[0027] Please refer to Figure 1 and Figure 2 as well as Figure 3 , both ends of the top of the base 1 are provided with T-shaped grooves 11. The T-shaped grooves 11 are slidably connected to the support 4 through T-shaped blocks. The T-shaped blocks are fixedly connected to the bottom of the support 4. The T-shaped blocks can be slidably arranged inside the T-shaped grooves 11, and at the same time, the T-shaped blocks can be fixed by the base 1. The T-shaped grooves 11 can guide and connect the support 4. The base 1 and the bracket 2 are connected by bolts. The bottom of the milling machine group 3 is connected to the top of the bracket 2. The support 4 is connected to the top of the base 1 by bolts.

[0028] The top of the support 4 is connected with a fixing mechanism 5. The fixing mechanism 5 includes a hydraulic rod 51 and a square block 53. The hydraulic rod 51 can drive the push plate 52. The push plate 52 and the C-shaped hollow plate 54 can cooperate to fix the steel trunnion group 7. The square block 53 can support the C-shaped hollow plate 54. The hydraulic rod 51 is connected to the base 1.

[0029] A push plate 52 is fixedly connected to the right side of the hydraulic rod 51. Guide grooves 41 are provided at both ends of the top of the support 4. The guide grooves 41 are connected to the push plate 52 through sliders. The guide grooves 41 can guide the push plate 52. A rubber plate 521 is fixedly connected to the right side of the push plate 52. The rubber plate 521 is a square sponge pad. The rubber plate 521 can prevent damage to the steel trunnion group 7 when the push plate 52 clamps the steel trunnion group 7.

[0030] The bottom of the square block 53 is connected to the right side of the top of the support 4. A C-shaped hollow plate 54 is fixedly connected to the left side of the square block 53. The inside of the C-shaped hollow plate 54 is slidably connected to the outside of the C-shaped plate 66. C-shaped grooves 541 are provided on both the inside of the C-shaped hollow plate 54 and the outside of the C-shaped plate 66. The C-shaped grooves 541 facilitate the milling machine group 3 to perform drilling and grooving operations on the steel trunnion group 7.

[0031] Please refer to Figure 4 and Figure 5 As shown in the figure, a support mechanism 6 is connected inside the C-shaped hollow plate 54. The support mechanism 6 includes a U-shaped arm 61. The U-shaped arm 61 can drive the rack 62. The U-shaped arm 61 is connected to the push plate 52. Rack bars 62 are connected to both ends on the right side of the U-shaped arm 61. The rack bars 62 can drive the gear 63 to rotate.

[0032] Please refer to Figure 6 As shown in the figure, the outside of the rack bar 62 is meshed with a gear 63. The gear 63 can drive a bidirectional lead screw 64 to rotate. The bidirectional lead screw 64 penetrates through the inside of the gear 63. The bidirectional lead screw 64 drives the threaded barrel 65 to move. A bearing is sleeved on the outside of the bidirectional lead screw 64. The bearing is connected to the inside of the C-shaped hollow plate 54. The bearing can support and limit the bidirectional lead screw 64. Threaded barrels 65 are threadedly connected to both the top and the bottom of the bidirectional lead screw 64.

[0033] A C-shaped plate 66 is sleeved on the outside of the threaded barrel 65. The C-shaped plate 66 can support the steel trunnion group 7. The C-shaped plate 66 slides inside the C-shaped hollow plate 54 and can then be guided by the C-shaped hollow plate 54 to perform a linear motion, preventing the threaded barrel 65 from rotating together with the bidirectional lead screw 64. A steel trunnion group 7 is movably connected to the top of the support 4. The steel trunnion group 7 is the steel trunnion to be processed by this device. The steel trunnion group 7 placed on the top of the support 4 can be taken out.

[0034] In this solution, the steel trunnion group 7 is first placed on the top of the support 4, and the right side of the steel trunnion group 7 is sleeved outside the C-shaped hollow plate 54. The hydraulic rod 51 is activated to drive the push plate 52 to move, and then the steel trunnion group 7 is clamped and fixed. At the same time, when the push plate 52 moves, it drives the C-shaped arm 61 to drive, and then drives the rack 62 to drive, so as to drive the meshing gear 63 to move, further drive the bidirectional lead screw 64 to rotate, and finally drive the threaded cylinder 65 and the C-shaped plate 66 to move away from each other to support the right side of the steel trunnion group 7. The milling machine group 3 is activated to perform drilling on the steel trunnion group 7;

[0035] When the steel trunnion group 7 is being processed, the added fixing mechanism 5 automatically clamps and fixes the steel trunnion group 7, avoiding the inconvenience of clamping and fixing the steel trunnion group 7 with traditional fixtures due to its special shape, thereby improving the processing speed of the steel trunnion group 7;

[0036] When the steel trunnion group 7 is fixedly clamped by the support 4, the added support mechanism 6 supports the drilling position of the steel trunnion group 7, avoiding the depression of the drilling position of the steel trunnion group 7 due to the hollow structure when being clamped and drilled.
