[0002] The drilling and tapping of reducer housing is a machining process that is usually used to create holes and threads on the reducer housing for the installation of other components or connecting devices. In order to ensure the accuracy and precision of the machining process, the reducer housing needs to be fixed and positioned with a fixture.

It is easily affected by the vibration and external force generated by processing, resulting in movement or deformation during the processing, thereby affecting the processing quality and accuracy. In view of this, the utility model proposes a fixture for drilling and tapping the reducer housing. Utility Model Content

[0023] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0025] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1-3As shown, the utility model proposes a fixture for drilling and tapping a reducer shell, comprising a hollow base 1 for placing the reducer shell, and the reducer shell is placed on the top of the base 1. The fixture also includes a clamping mechanism 2 installed on the base 1 for clamping and fixing the reducer shell, the clamping mechanism 2 includes a slide 21, a clamping plate 22, and a pressing plate 23, two groups of slides 21 are symmetrically opened on the top of the base 1, the clamping plate 22 is slidably connected in the slide 21, and the clamping plate 22 clamps and fixes the reducer shell after approaching each other. The two groups of pressing plates 23 are respectively fixedly connected to the side where the two groups of clamping plates 22 are close to each other, and the pressing plate 23 is arranged above the base 1. The pressing plate 23 can be pressed on the reducer shell when it moves downward synchronously with the clamping plate 22, so that the reducer shell is pressed on the top of the base 1, so that the reducer shell has high stability during processing. Rubber pads can be set on the side of the clamping plate 22 and the pressing plate 23 close to the reducer shell to prevent damage to the surface of the reducer shell.

[0029] Furthermore, the clamping mechanism 2 also includes a moving block 24, a threaded sleeve 25, a bidirectional threaded rod 26, and a rotating handle 27. The two groups of moving blocks 24 arranged in the base 1 are respectively slidably sleeved on the outer rings of the two groups of clamping plates 22. The threaded sleeve 25 arranged on one side of the clamping plate 22 is fixedly connected to one end of the moving block 24, and the threaded sleeve 25 moves synchronously with the moving block 24. The bidirectional threaded rod 26 rotatably connected to the base 1 is inserted into the threaded sleeve 25. One end of the bidirectional threaded rod 26 passes through one side of the base 1 and is fixedly connected to the rotating handle 27. The setting of the rotating handle 27 facilitates the rotation of the bidirectional threaded rod 26. The two ends of the bidirectional threaded rod 26 have opposite thread directions, and the two groups of threaded sleeves 25 are both threadedly connected to the bidirectional threaded rod 26, so that the bidirectional threaded rod 26 can drive the two groups of threaded sleeves 25 to move closer to or away from each other when rotating, and at the same time drive the two groups of moving blocks 24 to move closer to each other, and then drive the two groups of clamping plates 22 to move closer to each other to clamp the reducer housing. The clamping mechanism 2 also includes a limit sleeve 28 and a limit rod 29. The limit sleeve 28 is fixedly connected to the end of the moving block 24 away from the threaded sleeve 25. The limit sleeve 28 is slidably connected to the limit rod 29 fixedly installed in the base 1, and is used to limit the moving block 24 when it moves, so that the moving block 24 moves smoothly, and thus the clamping plate 22 moves smoothly.

[0030] Specifically, the clamp also includes a clamping assembly 3 for pressing the reducer housing on the top of the base 1. The clamping assembly 3 includes a sliding sleeve 31, a moving plate 32, and a push rod motor 33. Two sets of sliding sleeves 31 are respectively fixedly connected to the bottom of the two sets of clamping plates 22, and the sliding sleeves 31 move synchronously with the clamping plates 22. The moving plate 32 is slidably connected to the two sets of sliding sleeves 31, and is used to limit the position when the clamping plates 22 move. The output end of the push rod motor 33 installed on the top wall of the base 1 is fixedly connected to the center position of the moving plate 32. After the push rod motor 33 is extended, it drives the moving plate 32 to move downward, thereby driving the clamping plate 22 to move downward, and then the pressure plate 23 drives the reducer housing to press on the top of the base 1. The clamping assembly 3 also includes a slider 34 and a slide rail 35. The two sets of sliders 34 are respectively fixedly connected to the two ends of the movable plate 32. The sliders 34 are slidably connected to the slide rails 35 installed on the inner wall of the base 1. The slide rails 35 are arranged in an "I" shape and are used to limit the movable plate 32 when it moves, so that the movable plate 32 moves smoothly.

[0031] In this embodiment, first, the reducer housing to be processed is placed on the top of the base 1, and the rotating handle 27 is turned. The rotating handle 27 drives the bidirectional threaded rod 26 to rotate. Since the bidirectional threaded rod 26 is threadedly connected to the two groups of threaded sleeves 25 and the thread directions of the two ends of the bidirectional threaded rod 26 are opposite, the bidirectional threaded rod 26 can drive the two groups of threaded sleeves 25 to approach each other when rotating. At the same time, the two groups of moving blocks 24 are driven to move synchronously. The moving blocks 24 move smoothly under the limiting action of the limiting sleeve 28 and the limiting rod 29, so that the two groups of moving blocks 24 are stable. Drive the two groups of clamps 22 to approach each other. When the clamps 22 move, they drive the two groups of sliding sleeves 31 to slide on the movable plate 32, so that the movement of the clamps 22 is stable. At this time, the clamps 22 are close to each other to clamp the reducer housing. After that, the push rod motor 33 is started to extend, and the push rod motor 33 drives the clamping plate 22 to move downward. At this time, the movable plate 32 moves smoothly under the limiting action of the slider 34 and the slide rail 35, and drives the sliding sleeve 31 to move downward. The pressure plate 23 moves downward synchronously and presses the reducer shell on the top of the base 1, so that the reducer shell has good stability after being fixed, effectively preventing vibration and movement during the processing, and ensuring accuracy and precision during the processing.

[0032] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
