Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bearing seat processing, in particular to a guiding and positioning tool for processing an inclined hole of a bearing valve seat. Background Art
[0002] The bearing valve seat is a mechanical component used to fix and support bearings. It is widely used in a variety of mechanical equipment. It can enable the bearing to work stably in a fixed position, transfer loads and maintain smooth movement. During the production process of the bearing valve seat, in order to adapt to different installation environments, inclined holes are generally opened on the bearing valve seat according to the needs of the installation position to facilitate the fixing of the bearing valve seat and increase stability.
[0003] The existing method of drilling holes in bearing valve seats is generally to first fix the bearing valve seat on a workbench at a certain tilt angle, and then drill holes in the bearing valve seat through a drilling assembly. However, during the drilling process, since the bearing valve seat is tilted and fixed, the drill bit and the outer surface of the bearing valve seat are not drilled perpendicularly, and have a certain slope. When the drill bit is close to and squeezed against the bearing valve seat, a lateral movement force will be generated, which may cause position deviation or drill bit breakage. For this reason, we provide a guide positioning tool for bearing valve seat inclined hole processing to solve the above problems. Utility Model Content

[0027] A telescopic mechanism 4 is arranged on the upper surface of the workbench 1, and a threaded rod 5 is arranged on one side of the telescopic mechanism 4. There are two telescopic mechanisms 4, and the threaded rod 5 is arranged between the two telescopic mechanisms 4. The telescopic mechanism 4 includes a fixed box 401, and the lower surface of the fixed box 401 is fixedly connected to the workbench 1, and a second telescopic rod 402 is fixedly connected to the upper surface of the workbench 1. A sliding plate 403 is slidably connected to the inner wall of the fixed box 401, and the telescopic end of the second telescopic rod 402 penetrates the fixed box 401 and is fixedly connected to the sliding plate 403. The second telescopic rod 402 can drive the sliding plate 403 to move in the fixed box 401, and the fixed box 401 limits the sliding plate 403 to prevent the sliding plate 403 from tilting.
[0028] The outer surface of the threaded rod 5 is slidably connected with a sliding block 9, and the lower surface of the sliding block 9 is fixedly connected with an inclined block 6. There are two sliding blocks 9, which can prevent the inclined block 6 from tilting. One side of the inclined block 6 is an inclined surface, and the other side is a plane. The inclination angle is the same as the inclination angle of the inclined hole and the bearing seat. The inner wall of the inclined block 6 is rotatably connected with a rotating sleeve 7, and the material of the rotating sleeve 7 is rubber. The outer surface of the rotating sleeve 7 is fixedly connected with a limiting ring 8, and the outer surface of the limiting ring 8 is rotatably connected to the inclined block 6.

[0029] Working principle: When in use, the three first telescopic rods 302 are extended to drive the three extrusion plates 2 to move closer to the middle, and then the bearing seat is put on the three extrusion plates 2, and the side where the hole needs to be opened is facing the threaded rod 5. The first telescopic rod 302 is shortened to drive the extrusion plate 2 to squeeze the inner wall of the bearing seat, so that the bearing seat is fixed, achieving the effect of easy fixation. The motor 303 drives the rotating plate 301 to rotate through the belt 305 and the round rod 304. The rotating plate 301 drives the extrusion plate 2 to rotate through the first telescopic rod 302, so as to adjust the angle of the bearing seat, so that the side of the bearing seat that needs to be grooved is flush with the inclined surface of the inclined block 6. The two second telescopic rods 402 simultaneously drive the sliding plate 403 to slide in the fixed box 401, so that the inclined block 6 moves close to the bearing seat. , and then twist the rotating drum 10, which drives the inclined block 6 to slide on the threaded rod 5 to adjust the horizontal position of the inclined block 6, thereby facilitating the adjustment of the position of the inclined block 6, so that the inclined block 6 drives the rotating sleeve 7 to align with the position where the groove is required. At the same time, the inclined surface of the inclined block 6 contacts the outer surface of the bearing seat, and the threaded rod 5 and the sliding block 9 prevent the inclined block 6 from tilting. When drilling, the drill bit first passes through the rotating sleeve 7 and then drills the bearing seat. Since the side of the inclined block 6 away from the bearing seat is perpendicular to the drill bit, the rotating sleeve 7 limits the drill bit and fixes it to prevent the drill bit from deviating from the drilling position or breaking, thereby preventing the drill bit from deviating or breaking. The rotating sleeve 7 can rotate with the drill bit to reduce the friction between the inclined block 6 and the drill bit and increase the drilling effect.
