[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Combination Figures 1 to 4 An efficient tooling fixture for preventing deviation during engine casing processing includes a worktable 1, a long plate 2 and an engine casing 3. A limiting mechanism 5 is provided on the worktable 1 and the long plate 2, and a stabilizing mechanism 4 is provided on the limiting mechanism 5 and the engine casing 3.

[0029] The limiting mechanism 5 includes a moving component 51 and a limiting component 52, with the limiting component 52 disposed on the moving component 51;

[0030] The moving component 51 includes a T-slot 516, which is formed on the top of the worktable 1. Fixed seats 513 are fixedly connected to the left and right sides of the bottom of the long plate 2, respectively. A T-block 511 is fixedly connected to the bottom of the fixed seat 513. The surface of the T-block 511 is slidably connected to the inside of the T-slot 516. A fixed block 514 is fixedly connected to the center of the inner sides of the two long plates 2. A clamping ring 515 is fixedly connected to the other side of the fixed block 514. The clamping ring 515 is disposed on the surface of the engine housing 3. 1. Gear racks 519 are fixedly connected to the top left and right sides respectively. A dual-axis motor 512 is fixedly connected to the bottom center of the long plate 2. Rotary shafts 518 are fixedly connected to the left and right sides of the dual-axis motor 512. The surface of the rotating shaft 518 is rotatably connected to the inside of the fixed seat 513. Gears 517 are fixedly connected to the surface of the rotating shaft 518. There are four gears 517, which are in pairs. Two gears 517 are set on the outside of the two fixed seats 513. The surface of the gears 517 is meshed with the top of the T-slot 516.

[0031] The limiting component 52 includes a socket groove 521, which is formed around the left and right sides of the rotating shaft 518. The socket groove 521 is located between the fixed base 513 and the gear 517. A T-shaped rod 523 is inserted into the socket groove 521. Circular hole grooves 522 are formed inside the left and right sides of the long plate 2. Sliding grooves 524 are formed around the inner wall of the circular hole grooves 522. Long hole grooves 529 are densely formed inside the T-shaped rod 523. Long rods 526 are inserted into the long hole grooves 529. Slide plates 525 are fixedly connected to the four sides of the surface of the long rods 526. The surface of the slide plates 525 and the inside of the sliding grooves 524 are slidably connected. A mounting plate 528 is fixedly connected to the slide plates 525 and the side of the long rods 526 away from the long plate 2. Bolts 527 are threadedly connected to the mounting plate 528 and the inside of the long plate 2.

[0032] The long plate 2 has a through hole slot inside. The surface of the T-shaped insert 523 is inserted through the through hole slot inside the long plate 2. The left and right sides of the round hole slot 522 are set as openings. The round hole slot 522 and the through hole slot inside the long plate 2 are connected. The surface of the long insert 526 is inserted into the round hole slot 522.

[0033] Furthermore, the dual-axis motor 512 drives the rotating shaft 518 to rotate, and the rotating shaft 518 drives the gear 517 to rotate. The gear 517 can move on the top of the gear rack 519. When the gear 517 moves, the long plate 2 can move, which makes it easier for the clamping ring 515 to clamp and fix the engine housing 3. The T-shaped insert 523 is inserted into the insertion slot 521, and the long insert 526 is inserted into the long hole slot 529, so that the engine housing 3 will not shift position during the processing of the engine housing 3.

[0034] Example 2

[0035] See Figure 1-5 Furthermore, based on Embodiment 1, the stabilizing mechanism 4 includes a connecting seat 47, which is fixedly connected to the left and right sides of the clamping ring 515. A fixing rod 46 is fixedly connected to the top of the connecting seat 47, and a rotating plate 45 is rotatably connected to the surface of the fixing rod 46. A telescopic plate 44 is fixedly connected to the side of the rotating plate 45 near the long plate 2. A slot 43 is provided on the top of the long plate 2. Nuts 42 are fixedly connected to the front and rear sides of the long plate 2. A screw 41 is threadedly connected to the nuts 42, the telescopic plate 44, and the inside of the long plate 2. There are four slots 43, which are in pairs. The surface of the slot 43 is inserted into the inside of the telescopic plate 44. Two slots 43 are located inside the through hole slots opened inside the long plate 2.

[0036] Furthermore, the rotating plate 45 rotates on the surface of the fixed rod 46, causing the rotating plate 45 to drive the telescopic plate 44 to be set on the top of the slot 43. When the telescopic plate 44 is stretched and inserted into the slot 43, the screw 41 is used to thread and fix the nut 42, the telescopic plate 44 and the long plate 2, so that the clamping ring 515 can hold the engine housing 3 in a stable state.

[0037] In actual operation, when this device is used, the rotating plate 45 is rotated on the surface of the fixed rod 46, so that the rotating plate 45 drives the telescopic plate 44 to be set on the top of the slot 43. When the telescopic plate 44 is stretched and inserted into the slot 43, the screw 41 is used to thread and fix the nut 42, the telescopic plate 44 and the long plate 2, so that the clamping ring 515 can hold the engine housing 3 in a stable state.

[0038] When the dual-shaft motor 512 starts, it drives the rotating shafts 518 at both ends to rotate. The rotating shafts 518 drive the gear 517 to rotate. When the gear 517 and the gear rack 519 are meshed, the gear 517 can move on the top of the gear rack 519. When the gear 517 moves, the long plate 2 can move, which makes it easier for the clamping ring 515 to clamp and fix the engine housing 3. The T-shaped insert 523 is inserted through the through hole slot opened inside the long plate 2 and inserted into the insert slot 521. The mounting plate 528 drives the long insert 526 through the round hole slot 522 and inserted into the long hole slot 529. At the same time, the slide plate 525 is driven to slide in the slide groove 524. The mounting plate 528 and the long plate 2 are fixed by bolts 527, so that the engine housing 3 will not shift position during the processing of the engine housing 3.
