The figure is a simplified schematic diagram illustrating the basic structure of the utility model only by way of illustration, and therefore it shows only the constitution related to the utility model.

Referring to fig. 2-6, the present utility model provides an auxiliary tool for drilling a roller bearing seat of a belt type transfer conveyor for a coal mine, which is used for assisting the bearing seat 10 to drill a radial hole, specifically, assisting in finding the drilling position of the radial hole after the axial hole is drilled. This bearing frame appurtenance that punches includes spacing axle 1, fixedly connected with spliced pole 2 on the outer wall of spacing axle 1, spliced pole 2 and spacing axle 1 mutually perpendicular, spliced pole 3 is installed to the free end of spliced pole 2 (i.e. the one end of keeping away from spacing axle 1 on the spliced pole 2), spliced pole 3 is parallel to spacing axle 1 each other, movable column 4 is installed at the position that lies in between spliced pole 3 and spacing axle 1 on the spliced pole 2, movable column 4 and spacing axle 1 mutually parallel arrangement, and movable column 4 is slidable along the axial relative spliced pole 2 of spliced pole 2, marker 5 is installed to the free end of movable column 4 (i.e. the one end of keeping away from spliced pole 2 on the movable column 4), marker 5 and movable column 4 mutually perpendicular, the axis of spacing axle 1, the axis of spliced pole 3, the axis of movable column 4 and the axis of marker 5 are all in the coplanar.

When the two semicircular hoops forming the bearing seat 10 are spliced together to form a sleeve-shaped structure with two through ends, then the limiting shaft 1 is matched and inserted into a central through hole of the bearing seat 10, so that the limiting shaft 1 can move along the axial direction of the bearing seat 10 and can rotate relative to the bearing seat 10, when the limiting shaft 1 cannot be assembled in the central hole of the bearing seat 10, the inserting column 3 is opposite to the axial hole at the edge of the bearing seat 10, then the limiting shaft 1 is moved, the inserting column 3 is inserted into the axial hole, meanwhile, the movable column 4 also extends into the bearing seat 10 together, when the extending length of the movable column 4 reaches the target length, the movable column 4 slides relative to the connecting column 2 in the direction away from the limiting shaft 1 at the moment, the marker pen 5 is driven to move together, and finally the marker pen 5 is enabled to leave marks in the bearing seat 10, and the positions of the marks are the positions of radial holes to be drilled. Because the central axis of the limiting shaft 1, the central axis of the inserting column 3, the central axis of the movable column 4 and the central axis of the marking pen 5 are all in the same plane, and the marking pen 5 is mutually perpendicular to the movable column 4, the radial hole drilled out is communicated with the axial hole, and the radial hole is mutually perpendicular to the axial hole, so that the precision of drilling the oiling channel is ensured.

The limiting shaft 1 is of a cylindrical structure, the lower end of the connecting column 2 is fixedly connected with a fixing ring 21, the fixing ring 21 is fixedly sleeved outside the limiting shaft 1, and the fixing ring 21 is fixedly connected with the limiting shaft 1 through welding. The upper end of the connecting column 2 is fixedly connected with a connecting sleeve 22, and the inserting column 3 is arranged on the connecting sleeve 22. In this embodiment, the plug 3 is rotatably connected to the connecting sleeve 22, and the plug 3 is a bolt that is coupled to the axial hole of the bearing housing 10. When the movable column 4 is in use, when the inserting column 3 moves to the orifice of the axial hole, the inserting column 3 is rotated, the inserting column 3 is gradually inserted into the axial hole under the action of the threaded fit, and meanwhile, the limiting shaft 1 is driven to move along the central hole of the bearing seat 10 by the movement of the inserting column 3, so that the movable column 4 and the marker pen 5 are driven to move along the axial direction of the bearing seat 10. By moving the movable column 4 in a threaded fit screwing manner, an axial micro distance adjusting function can be realized, so that the fine adjustment of an operator is facilitated, and the moving precision of the marker pen 5 is ensured.

Further, an operation handle 31 is fixedly connected to one end of the plunger 3, and the operation handle 31 is held by a user for the operator to rotate the plunger 3. In addition, a bearing 32 is installed between the plug post 3 and the connecting sleeve 22, the outer ring of the bearing 32 is fixedly embedded in the connecting sleeve 22, and the inner ring of the bearing 32 is fixedly sleeved outside the plug post 3.

In other embodiments not shown, the plunger 3 may be a polished rod, and the axial hole on the bearing seat 10 is a light hole, and at this time, the operator only needs to slide the limiting shaft 1 along the axial direction of the bearing seat 10 to drive the movable column 4 to move, so as to move the marker pen 5 to the target position.

The end of the movable column 4 is fixedly connected with a slip ring 41, the slip ring 41 is slidably sleeved outside the connecting column 2, a locking bolt 42 is installed on the slip ring 41, one end of the locking bolt 42 abuts against the outer wall of the connecting column 2 after penetrating through the slip ring 41, so that after an operator tightens the locking bolt 42, the slip ring 41 and the movable column 4 can be locked on the connecting column 2, when the rotation limiting shaft 1 is avoided, the movable column 4 slides randomly, and a marking pen 5 can leave an error mark on the inner wall of the bearing seat 10 by mistake.

In this embodiment, the distance from the tip of the marker 5 to the connecting post 2 is equal to the distance from the free end of the plunger 3 to the connecting post 2. Thus, the radial hole obtained by drilling is likely to be communicated with the axial hole. In addition, a scale 6 is arranged on the outer wall of the movable column 4 along the axial direction of the movable column 4, and the 0 position on the scale 6 corresponds to the pen point of the marker 5, so that an operator can know the depth of the movable column 4 extending into the bearing seat 10 through the alignment relation between the scale and the end surface of the bearing seat 10, and the extending distance of the marker 5 is determined.
