Problems solved by technology
[0005] The above-mentioned existing technical solutions have the following defects: since the inclination angle of the seat body is determined by manual placement, the accuracy is low
If the inclination angles of the inclined holes are different and the placement angles of the seat body are also different, re-clamping is required; after one inclined hole is processed, when the next inclined hole is processed, the seat body needs to be rotated again and re-clamped Therefore, the processing of the existing bearing seat is more troublesome, and multiple clamping and positioning are required, which easily leads to low processing efficiency of the bearing seat

Embodiment
[0051] refer to figure 2 and image 3 , the present invention discloses a device for processing oblique holes in the circumferential direction of bearing seats, including a machining center, an indexing head 7 and a chucking plate 3, the machining center includes a working table 2 and a rotating main shaft 21, and the indexing head 7 is installed on the working surface through bolts. On the table top 2 , the clamping disc 3 is installed on the main shaft 75 of the indexing disc 73 , and the base 1 is installed on the clamping disc 3 . In this embodiment, the end of the main shaft 75 facing the clamping disc 3 is connected with a flange 76 by bolts, and the flange 76 is embedded on one side of the clamping disc 3 and connected with the clamping disc 3 by bolts, so that the clamping can be lifted The stability of the connection of the disc 3 to the spindle 75.
[0052] By turning the shedding screw handle 77 of the index plate 73, the body 78 of the index head 7 is rotated, s...

The invention discloses a device for machining a circumferential oblique hole of a bearing seat, which relates to the technical field of bearing seat processing, and comprises a machining center, an indexing head and a chucking plate, the machining center includes a working table and a rotating main shaft, and the indexing head is detachable It is connected to the working table, the input end of the dividing head is connected with the rotating main shaft, the clamping disc is connected with the main shaft of the dividing head, and the seat body is detachably connected with the clamping disc. The invention solves the problems that multiple inclined holes on the bearing seat need to be clamped and positioned multiple times, which easily leads to low processing efficiency and poor processing accuracy of the bearing seat, and is convenient for one-time clamping and positioning to process the same bearing There are multiple inclined holes on the bearing seat, and the effect of improving the processing efficiency of the inclined holes on the bearing seat can be achieved under the condition of meeting the machining accuracy requirements.
Description
technical field [0001] The invention relates to the technical field of bearing housing processing, in particular to a device for machining a circumferential oblique hole of a bearing housing. Background technique [0002] At present, the bearing seat is used to support the bearing, and the outer ring of the fixed bearing is only allowed to rotate the inner ring, while the outer ring remains stationary, and is always consistent with the direction of transmission, and maintains balance. The scientific definition of a bearing seat is a component installed on the cylinder body or foundation of a steam turbine to support the bearing. Since a bearing can choose different bearing seats, and a bearing seat can choose different types of bearings at the same time, there are many varieties of bearing seats. [0003] Existing bearing housings such as figure 1 As shown, the seat body 1 is included. The seat body 1 includes an integrally formed base 11 and a ring seat 12 . The outer dia...
