Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of clamps, and in particular, relates to a bearing cover clamping tool. Background Art
[0002] The bearing cap is an important supporting structure in the gearbox of a heavy-duty vehicle. Its accuracy directly affects the position accuracy of the spatial axis system in the gearbox, the meshing accuracy of the gears, and the vibration and noise of the whole machine. Therefore, its processing accuracy is very important. For a bearing cap with multiple hole systems at both ends, after the hole system at one end is processed, the entire bearing end cap is usually turned over and fixed, and then the hole system at the other end is directly processed. This processing cannot guarantee the relative position accuracy of the hole systems at both ends of the bearing cap. Utility Model Content
[0003] The embodiment of the present application provides a bearing cover clamping tool. After being clamped and positioned by the tool, the relative position accuracy of the hole systems at both ends of the machined bearing end cover is better.
[0004] A bearing cover clamping tool, comprising:
[0005] roof;
[0006] A bottom plate, the bottom plate is located below the top plate, and the top plate and the bottom plate are connected via pillars;
[0007] An assembly groove is provided on the lower side of the top plate, and the assembly groove is used to cooperate with the flange on one end of the bearing cover to be processed. The top plate is also provided with a positioning hole and a plurality of through holes. The distribution positions of the through holes on the top plate are the same as the distribution of the holes to be processed at one end of the bearing cover to be processed. The positioning hole is used to correspond to the hole position on one end of the hole system that has been processed on the bearing cover, and a positioning axis is passed through the positioning hole and one of the hole positions on one end of the hole system that has been processed on the bearing cover.
[0008] According to some other embodiments of the bearing cover clamping tool of the present invention, a pushing device is installed on the bottom plate, and the pushing device is used to press the bearing cover against the lower side of the top plate.
[0009] According to the bearing cover clamping tooling of other embodiments of the present invention, the four corners of the top plate and the four corners of the bottom plate are connected by the pillars.
[0010] According to some other embodiments of the bearing cover clamping tool of the present invention, an avoidance window is provided on the top plate, and the avoidance window is used to correspond to the surface to be processed of the bearing cover.
[0011] According to the bearing cover clamping tooling of some other embodiments of the utility model, the support column is detachably connected to the top plate.
[0012] According to the bearing cover clamping tool of some other embodiments of the utility model, the support column is detachably connected to the base plate.
[0013] According to some other embodiments of the bearing cover clamping tool of the present invention, seven through holes are provided on the top plate.
[0014] The bearing cover clamping tooling of the utility model embodiment has at least the following beneficial effects: during use, the bearing cover is arranged between the top plate and the bottom plate, one end of the bearing cover with the processed hole system is located at the bottom, and the end of the bearing cover with the to-be-processed hole system is located at the top, and the flange at one end of the bearing cover with the to-be-processed hole system is assembled in the assembly groove on the lower side of the top plate, so that one end of the bearing cover with the to-be-processed hole system is kept in cooperation with the top plate, and then the positioning shaft is passed through the positioning hole and one of the hole positions at one end of the bearing cover with the processed hole system, so that the positions of the holes to be processed on the bearing cover and the positions of the through holes on the top plate can be ensured to correspond to each other through the top plate through the limitation of the positioning shaft and the limitation of the flange and the assembly groove. During the processing, the drilling tool can directly pass through the through hole to process the corresponding hole position at one end of the bearing cover with the to-be-processed hole system. Since the positioning shaft of this tooling connects the top plate and the hole position at one end of the processed hole system of the bearing cover, the relative position accuracy of the processed hole systems at both ends of the bearing end cover is better.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0022] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" 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 directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.
[0023] In the embodiments of the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0024] The bearing cap is an important supporting structure in the gearbox of a heavy-duty vehicle. Its accuracy directly affects the position accuracy of the spatial axis system in the gearbox, the meshing accuracy of the gears, and the vibration and noise of the whole machine. Therefore, its processing accuracy is very important. For a bearing cap with multiple hole systems at both ends, after the hole system at one end is processed, the entire bearing end cap is usually turned over and fixed, and then the hole system at the other end is directly processed. This processing cannot guarantee the relative position accuracy of the hole systems at both ends of the bearing cap.
[0025] For example, for a bearing cover having seven hole systems at one end and four hole systems at the other end, usually the end with the four hole systems has been processed. During the processing of the seven hole systems at the other end, the entire bearing end cover is directly fixed, and then one end with the seven hole systems is directly processed. Such processing cannot ensure the relative position accuracy between one end of the bearing cover with the seven hole systems and one end with the four hole systems.

During the processing, the drilling tool can directly pass through the through hole 1c to process the corresponding hole position at one end of the bearing cover 4 with the hole system to be processed.
