Description

Technical Field

[0001] The utility model relates to the technical field of bearing seat processing, in particular to a bearing seat processing fixing fixture. Background Art

[0002] A disc bearing seat is a large and extra-large bearing seat with a special structure that can accept comprehensive loads. It has the characteristics of compact structure, flexible rotation, and easy installation and maintenance. Where there is a bearing, there must be a support point. The inner support point of the bearing is the shaft, and the outer support is what is often called the bearing seat. Because one bearing can use different bearing seats, and one bearing seat can also use different types of bearings.

[0003] During the processing of the bearing seat, a fixing fixture is needed to fix it. When the existing fixing fixtures clamp and fix the bearing seat, most of them only clamp and fix the outer sides of the bearing seat, and do not have the function of fixing the inner wall of the bearing seat. As a result, when performing some processing with large impact forces, the bearing seat is very likely to shake, which is not conducive to the use of staff. For this reason, we propose a bearing seat processing fixing fixture. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A bearing seat processing and fixing fixture comprises a shell, one side of the shell is rotatably connected to a first rotating shaft, one end of the first rotating shaft extends to the interior of the shell, one end of the first rotating shaft is fixedly connected to a bidirectional screw, the outside of the bidirectional screw is provided with a clamping assembly, the top of the shell is provided with two symmetrically distributed arc-shaped clamping plates, the top of the shell is provided with a limiting assembly, the outside of the bidirectional screw is provided with a first transmission assembly, the top of the inner wall of the shell is rotatably connected to a second rotating shaft, the outside of the second rotating shaft is provided with a second transmission assembly, and the top of the inner wall of the shell is provided with a sliding assembly.

[0007] Preferably, a handle is fixedly connected to one side of the first rotating shaft, and the handle is made of rubber.

[0008] Preferably, the clamping assembly includes two symmetrically distributed threaded sleeves threadedly connected to the outside of the bidirectional screw, the tops of the two threaded sleeves are fixedly connected to the first slider, and the bottom of the arc-shaped clamping plate is fixedly connected to the top of the first slider.

[0009] Preferably, the limiting assembly comprises two symmetrically distributed first sliding grooves opened on the top of the shell, and the two first sliding blocks are slidably connected inside the corresponding first sliding grooves.

[0010] Preferably, the first transmission assembly includes a first bevel gear fixedly sleeved on the outside of the bidirectional screw, and the bottom of the second rotating shaft is fixedly connected to a second bevel gear, and the first bevel gear is meshingly connected with the second bevel gear.

[0011] Preferably, the sliding assembly comprises two symmetrically distributed sliding rails fixedly connected to the top of the inner wall of the shell, and the outside of the sliding rails is slidably connected to a sliding platform.

[0012] Preferably, the second transmission assembly includes a gear fixedly sleeved on the outside of the second rotating shaft, the bottoms of the two slides are fixedly connected to racks, the gears are meshingly connected to the two racks, one side of the two slides is fixedly connected to a second slider, the top of the shell is provided with two second slide grooves distributed on the bottom side, and the second slider is slidably connected to the inside of the second slide groove.

[0013] Compared with the prior art, the beneficial effect of the utility model is as follows: during the processing of the bearing seat, when the bearing seat needs to be fixed, the rotating handle is held to drive the first rotating shaft and the bidirectional screw to rotate, and then the two threaded sleeves, the first slider and the arc clamping plate are driven to move oppositely. The arc clamping plate moves to both sides of the bearing seat, and the bearing seat can be clamped and fixed. The first bevel gear rotates, and the second bevel gear, the second rotating shaft and the gear rotate. Through the rotation of the gear, the two racks, the slide table and the second slider can be driven to move oppositely. At this time, the two second sliders will move to the inner ring of the bearing seat, and the inner ring of the bearing seat can be clamped and fixed. Through the above structure, it is convenient for the staff to clamp and fix the bearing seat in and out during the processing of the bearing seat. During the fixing process, the two sides and the inner wall of the bearing seat can be clamped and fixed at the same time, and the fixing effect is better. Even if a large force is generated during the processing, it will not cause the bearing seat to shake, which greatly facilitates the use of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
