Description

Technical Field

[0001] The utility model relates to the technical field of reducer production, in particular to a machining device for mounting holes on the outer surface of a reducer housing during production. Background Art

[0002] A reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching speeds and transmitting torques between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] End covers need to be provided at the ends of the internal transmission shafts and at the connection positions between the output shafts and the housing of the reducer housing. These end covers are usually detachable and fixed by screws, which requires threaded holes to be opened on the outer surface of the housing. Since the housing is a split structure and the threaded holes are evenly distributed, it is difficult to clamp, so it is difficult to open the threaded holes. Therefore, while effectively clamping the housing, it is necessary to quickly and effectively position the opened threaded holes. Summary of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a machining device for mounting holes on the outer surface of a reducer housing during production.

[0005] The utility model is realized by the following technical solutions:

The directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only references to the directions in the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0024] As Figures 1-4 shown, a machining device for the outer surface mounting holes of a reducer housing includes a mounting table 1, a connecting frame 2, a spring 3, a positioning device 4, an adjustment mechanism 5, an upper housing 6, a lower housing 7, and auxiliary equipment 8. The connecting frame 2 is fixedly arranged inside the top of the mounting table 1. The spring 3 is sleeved outside the connecting frame 2. The positioning device 4 is sleeved outside the connecting frame 2. The adjustment mechanism 5 is movably connected to the top of the mounting table 1. The upper housing 6 is connected to the lower housing 7. The auxiliary equipment 8 is clamped inside the upper housing 6 and the lower housing 7. The positioning device 4 includes a pressing plate 41, a pull rod 42, and an inserting rod 43. The pull rod 42 is fixedly arranged at the bottom of the pressing plate 41. The inserting rod 43 is fixedly arranged on the upper surface of the pressing plate 41. The adjustment mechanism 5 includes a rotating table 51, a support bar 52, an inserting block 53, and a connecting shaft 54. The connecting shaft 54 is fixedly arranged at the bottom of the rotating table 51. The connecting shaft 54 is movably connected to the top of the mounting table 1. The support bar 52 is fixedly arranged on the upper surface of the rotating table 51. The inserting block 53 is fixedly arranged in the middle of the rotating table 51.

[0025] Specifically, the auxiliary device 8 includes a connecting seat 81, a limiting ring 82 and a connecting rod 83. The connecting seat 81 is fixedly connected through the connecting rod 83. The limiting ring 82 is fixedly arranged outside both ends of the connecting seat 81. The connecting seat 81 is of a cylindrical structure, and its outer diameter matches the sizes of the side end covers of the upper housing 6 and the lower housing 7 or the drive shaft mounting holes. Jacks for mating with the insertion blocks 53 are provided at both ends of the connecting seat 81. The top of the insertion rod 43 penetrates through the mounting table 1 and extends to the bottom of the rotating table 51. A limiting jack for mating with the insertion rod 43 is provided at the bottom of the rotating table 51. The pressing plate 41 is sleeved on the top of the connecting frame 2. The spring 3 is arranged at the bottom of the pressing plate 41. The ends of the connecting seat 81 are located in the same plane, and the bottom of the connecting seat 81 contacts the upper surface of the support bar 52.

[0026] In this embodiment, first, according to the size of the reducer, the auxiliary device 8 that meets the internal installation requirements is set. The outer diameter of the connecting seat 81 of the auxiliary device 8 matches the inner diameter of the end cover mounting hole. Limiting jacks for mating with the insertion blocks 53 are provided at both ends of the connecting seat 81. The connecting seat 81 is fixed through the connecting rod 83. After the auxiliary device 8 is clamped into the top slot of the lower housing 7 in this way, the outer side of the limiting ring 82 contacts the inner side of the lower housing 7. Subsequently, the upper housing 6 is covered and the upper housing 6 and the lower housing 7 are connected by bolts.

[0027] Furthermore, when installing the upper housing 6 and the lower housing 7 equipped with the auxiliary device 8, only need to clamp the limiting jacks at the ends of the connecting seat 81 in the auxiliary device 8 to the top of the insertion blocks 53. At this time, the support bar 52 on the upper surface of the rotating table 51 contacts the bottom of the connecting seat 81, playing a supporting role to ensure that the opened mounting holes are in a vertical state. During the machining process of the mounting holes, pull down the pull rod 42 to press down the pressing plate 41 and compress the spring 3. At this time, the insertion rod 43 will separate from the bottom of the rotating table 51, so as to operate the rotating table 51 to switch the machining area. After releasing the pull rod 42, the insertion rod 43 is clamped into the limiting jack at the bottom of the rotating table 51 again under the action of the spring 3, so as to replace and lock the machining areas on the surfaces of the upper housing 6 and the lower housing 7, effectively realizing the work of uniformly opening the end cover mounting holes on the surfaces of the upper housing 6 and the lower housing 7 and ensuring the machining quality of the mounting holes.
