[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-3 A speed reducer fixing fixture includes a base 1, with support plates 2 slidably fitted on both sides of the top of the base 1, and L-shaped positioning seats 3 integrally fixed to the top of each of the two support plates 2, and the two L-shaped positioning seats 3 are symmetrically distributed, and a speed reducer 4 to be fixed is detachably placed on the two L-shaped positioning seats 3.

[0026] Two strip holes 5 are opened on the inner top of the L-shaped positioning seat 3 along the same straight line. Locking bolts 6 are installed through the strip holes 5, and the top of the locking bolts 6 passes through the pre-opened assembly hole on the housing of the reducer 4 to be fixed and forms a locking fixation.

[0027] A bearing seat 7 is vertically fixed at the top center of the base 1. A double-ended screw 8 is rotatably assembled inside the bearing seat 7. Two L-shaped positioning seats 3 are respectively sleeved on the outer ends of the double-ended screw 8 through a threaded structure.

[0028] By adopting the above technical solution, the tooling base 1 is slidably engaged with the support plate 2 on both sides of its top, and together with two symmetrically distributed L-shaped positioning seats 3, the reducer 4 to be fixed is supported, thus achieving the initial positioning of the reducer. The slotted holes 5 on the L-shaped positioning seats 3 are used to adapt to the installation positions of reducers 4 of different specifications. The locking bolts 6 pass through the pre-drilled assembly holes on the housing of the reducer 4 to form a double fixation, ensuring the fixation is firm. The double-ended screw 8 is supported by the bearing seat 7, and the double-ended screw 8 is threadedly connected to the L-shaped positioning seats 3, driving the two L-shaped positioning seats 3 to slide synchronously in opposite directions. This can flexibly adapt to reducers of different sizes, significantly improving the versatility and ease of adjustment of the tooling.

[0029] The threads at both ends of the double-ended screw 8 are turned in opposite directions, and a rotating handle 9 is fixed to one end of the double-ended screw 8 away from the bearing seat 7.

[0030] Using the above technical solution, the opposite thread directions at both ends of the double-ended screw 8 ensure that the two L-shaped positioning seats 3 can be precisely clamped in opposite directions or released in reverse when rotated, avoiding displacement deviation during the adjustment process; the rotating handle 9 integrally fixed at one end of the double-ended screw 8 provides the operator with a convenient point of force application.

[0031] Both sides of the top of the base 1 are integrally fixed with folded edge plates 10, and multiple guide rods 11 are fixedly installed in parallel between the two folded edge plates 10.

[0032] A sliding bushing 12 is fixedly installed on the support plate 2 at the position corresponding to each guide rod 11. The sliding bushing 12 is fitted with a gap on the outside of the corresponding guide rod 11 to form a sliding fit.

[0033] The contact surface between the bottom of the support plate 2 and the top of the base 1 is an arc-shaped structure.

[0034] Using the above technical solutions, the folded edge plates 10 on both sides of the top of the base 1 provide a stable mounting carrier for multiple guide rods 11, ensuring that the guide rods 11 always remain parallel; the sliding bushing 12 on the support plate 2 and the clearance fit with the corresponding guide rod 11 can limit the sliding direction of the support plate 2, preventing tilting, jamming or offset when it drives the L-shaped positioning seat 3 to slide, and ensuring the straightness of the movement trajectory of the L-shaped positioning seat 3; the arc-shaped contact surface between the bottom end of the support plate 2 and the top end of the base 1 can reduce the contact area and frictional resistance when the two slide, making the adjustment of the L-shaped positioning seat 3 by the support plate 2 smoother.

[0035] Both support plates 2 have internal threaded bushings 13 fixedly installed through the middle of their sides. The internal threads of the internal threaded bushings 13 are matched with the external threads at both ends of the double-ended screw 8, and the two internal threaded bushings 13 are respectively threaded onto the outer ends of the double-ended screw 8.

[0036] Using the above technical solution, the internal threaded bushing 13 is fixedly inserted through the middle of the side of the support plate 2. Its internal thread is precisely matched with the external threads at both ends of the double-ended screw 8, which can efficiently transmit the rotational power of the double-ended screw 8 to the support plate 2, avoiding problems such as thread slippage and power loss, and ensuring that the double-ended screw 8 can synchronously drive the two support plates 2 to move the L-shaped positioning seat 3 when rotating.

[0037] Limiting rings 14 are fitted on both ends of the double-ended screw 8 at the bearing housing 7.

[0038] Using the above technical solution, the limiting rings 14 fitted on the double-ended screw 8 at both ends of the bearing housing 7 can effectively limit the axial displacement of the double-ended screw 8, prevent it from moving along the axial direction during rotation, and ensure that the double-ended screw 8 always maintains a stable rotation state within the bearing housing 7.

[0039] Multiple reinforcing ribs 15 are installed at intervals between the side of the support plate 2 and the bottom of the L-shaped positioning seat 3;

[0040] Mounting plates 16 are fixed to both sides of the base 1, and multiple mounting holes are spaced apart on the mounting plates 16.

[0041] By adopting the above technical solutions, the reinforced corner rib 15 can enhance the connection strength between the L-shaped positioning seat 3 and the support plate 2, effectively disperse the pressure generated on the L-shaped positioning seat 3 after the reducer 4 to be fixed is placed, and prevent the L-shaped positioning seat 3 from sinking, tilting or deforming due to excessive force, thus ensuring the levelness and stability of the reducer after it is fixed; the mounting plates 16 and their multiple mounting holes fixed on both sides of the base 1 can be used to fix the tooling as a whole on the workbench or ground through bolts and other connecting parts, so as to prevent the tooling from shifting due to external force during operation, and improve the safety and reliability of the reducer 4 to be fixed during processing and maintenance.

[0042] Working principle:

[0043] First, the fixture is fixed to the workbench through the mounting holes of the mounting plates 16 on both sides of the base 1. Then, the rotating handle 9 at the end of the double-ended screw 8 is rotated. Since the threads at both ends of the double-ended screw 8 turn in opposite directions and are connected to the support plate 2 through the internal thread bushing 13, the two support plates 2 can be driven to slide synchronously in opposite directions along the cooperation structure of the guide rod 11 and the sliding bushing 12. This drives the L-shaped positioning seat 3 at the top to adjust the spacing to match the size of the reducer 4 to be fixed. After the reducer 4 to be fixed is placed on the two L-shaped positioning seats 3, the locking bolt 6 is passed through the strip hole 5 of the L-shaped positioning seat 3 and the assembly hole pre-drilled in the reducer housing and locked. At the same time, the reinforcing rib 15 between the support plate 2 and the L-shaped positioning seat 3 enhances the structural stability, and finally the reducer is accurately fixed.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
