Description

Technical Field

[0001] The utility model relates to the technical field of fixing jigs, and more specifically, to a fixing device for boring holes in a bearing seat. Background Technique

[0002] A bearing seat is a mechanical part mainly used to support a bearing and fix the outer ring of the bearing, allowing only the inner ring to rotate to maintain consistency with the transmission direction. It is widely used in various fields such as machinery, industry, automobiles, aerospace, etc. During the processing and manufacturing of bearing seats, it is necessary to use a lathe to bore holes in the installation part of the bearing seat to cut out installation holes for the installation and use of the bearing seat. Currently, a fixing device for boring holes in a bearing seat is mostly used.

[0003] The prior art discloses a high - efficiency bearing seat drilling and fixing tooling with the publication number: CN216264653U, which includes a fixture body, an adjusting support with a nut, a double - headed bolt with a nut, and a movable drilling plate. It is specially provided with a movable drill template. The movable drill template is provided with both 3mm - 6mm protrusions and drill holes. The movable drill template can fix the workpiece in the vertical direction and can also drill the workpiece through the drill holes. During the drilling process, it can reduce the swing amplitude of the drill bit and ensure the drilling accuracy of the bearing seat. The quick - change drill sleeve in the drill hole can prevent the drill hole from expanding and affecting the drilling accuracy. In the actual use process, to further ensure the drilling accuracy, the quick - change drill sleeve needs to be replaced after wear. The double - headed bolt with a nut and the adjusting support can be adjusted according to the height of the bearing seat, which is applicable to the drilling of bearing seats of various specifications, has strong versatility, a simple structure, and reduces production costs.

[0004] When the above - mentioned utility model is in use, the movable drilling plate is used in cooperation with the adjusting support with a nut and the double - headed bolt with a nut to realize the vertical limit clamping and fixing of bearing seat workpieces of various specifications. However, manually adjusting the adjusting support with a nut and the double - headed bolt with a nut is rather cumbersome and inconvenient. Moreover, before the bearing seat workpiece is fixed, it is difficult to align its center line with the center of the workpiece placement table, which affects the subsequent boring accuracy, and its practicability is relatively general.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a fixing device for boring a bearing seat, which has the following beneficial effects:

[0017] (1) The present utility model is provided with a fixing frame, a workpiece placing table, positioning clamping plates and a moving drilling plate. During use, a worker can place a bearing seat workpiece in the center of the top surface of the workpiece placing table, and then start a first small motor through a control panel. A cross-shaped chute is provided on the top surface of the workpiece placing table, and four mounting frames are fixedly installed in the cross-shaped chute. A first adjusting lead screw is installed on the mounting frame. One end of a first adjusting lead screw is connected to the output end of the first small motor. Conical gears are fixedly installed at the opposite ends of the four first adjusting lead screws, and adjacent conical gears mesh with each other. Guide sliders are welded to the bottom ends of the four positioning clamping plates, and the guide sliders are clamped in the cross-shaped chute. A first lead screw sleeve fixedly installed in the guide slider is matched with the first adjusting lead screw. Therefore, when the first small motor drives one first adjusting lead screw to rotate, the four adjusting lead screws can rotate simultaneously and drive the four positioning clamping plates to move towards the center of the workpiece placing table along the direction of the cross-shaped chute. When the four positioning clamping plates are in contact with the four side walls of the bearing seat workpiece, it can not only initially clamp and fix the bearing seat workpiece, but also ensure that the center line of the bearing seat workpiece is aligned with the center line of the workpiece placing table, so as to improve the subsequent boring processing accuracy. After the positioning clamping plates initially fix the bearing seat workpiece, the worker can start a second small motor through the control panel to drive a second adjusting lead screw installed on a side fixed block. Since a second lead screw sleeve fixedly installed on one side of the moving drilling plate is matched with the second adjusting lead screw, and a guide rod is sleeved in a guide slider fixedly installed on the other side of the moving drilling plate, the rotation of the second adjusting lead screw can drive the moving drilling plate to move downward until a fixed protrusion fixedly installed on the bottom surface of the moving drilling plate is in contact with the top of the bearing seat workpiece, realizing further fixation of the bearing seat workpiece to improve its stability during processing. Multiple groups of drilling holes are symmetrically provided on the moving drilling plate to meet the boring processing of bearing seat workpieces with different specifications of diameters. Thus, a fixing device for boring a bearing seat has a high degree of automation, is simple and convenient to operate, can automatically and quickly align the center line of the bearing seat workpiece with the center line of the workpiece placing table to improve the subsequent boring processing accuracy, and can more stably clamp and fix bearing seat workpieces of various specifications, with stronger practicability.

[0018] (2) The utility model is provided with a fixing frame, a workpiece placing table and a third small motor. A rotating chute is opened in the center of the provided fixing frame. A rotating sliding ring is fixedly installed on the side wall of the provided workpiece placing table, and the rotating sliding ring is clamped in the rotating chute. Therefore, the workpiece placing table can drive the bearing seat workpiece to rotate around the rotating chute. When a circle of mounting holes needs to be machined on the bearing seat workpiece, after the worker finishes drilling a pair of mounting holes, the movable drilling plate can be reset, and then the third small motor is started through the control panel to drive the rotating shaft to stepwise rotate a certain angle. Since an adjusting gear is fixedly installed on the provided rotating shaft, and an adjusting gear ring is fixedly installed on the side wall of the workpiece placing table, and the adjusting gear ring meshes with the adjusting gear, the rotating shaft can drive the workpiece placing table together with the bearing seat workpiece to rotate a certain angle. Then, the movable drilling plate is lowered again, and the hole machining operation is carried out again. By circulating like this, a circle of mounting holes can be quickly machined on the bearing seat workpiece. The operation is simple and convenient, the hole machining efficiency of the bearing seat is improved, and the practicability is stronger. Brief Description of the Drawings
