Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a drilling device for producing bearings. Background Technology

[0002] In the field of mechanical manufacturing, bearings, as key basic components, are widely used in many industries such as automobiles, aerospace, industrial equipment, and medical devices. Their performance directly affects the operating accuracy, stability, and reliability of mechanical systems. Drilling is a crucial process in bearing production. The drilling accuracy of the inner and outer rings of the bearing not only affects the compatibility of subsequent component installation but also significantly impacts the overall rotational accuracy and service life of the bearing.

[0003] Currently, during bearing drilling operations, the inner and outer rings of the bearing must first be clamped and fixed to ensure the accuracy of the drilling position. However, existing bearing drilling devices have significant shortcomings when clamping bearing inner and outer rings of different sizes. On the one hand, most traditional clamping devices have fixed structures and can only clamp bearing inner and outer rings of specific sizes. When processing bearings of different specifications and sizes, it is often necessary to replace the entire clamping component, or even different drilling equipment, which not only increases production costs but also greatly reduces production efficiency. On the other hand, for some adjustable clamping devices, their adjustment mechanisms are complex, and the adjustment accuracy is difficult to guarantee. During the clamping process, the inner and outer rings of the bearing are prone to misalignment, resulting in drilling position deviations and affecting the quality of the bearing.

[0004] Maintaining concentricity between the inner and outer rings of a bearing is crucial for ensuring drilling accuracy. If the inner and outer rings are not concentric, the position of the drilled hole relative to the bearing's central axis will shift or become misaligned. This will cause vibration and noise during bearing operation after installation, and in severe cases, lead to bearing failure and shorten its service life. Existing drilling devices, due to defects in their clamping and fixing methods, struggle to meet the concentric clamping requirements of bearings of different sizes, thus hindering improvements in bearing production quality.

[0005] Therefore, developing a bearing drilling device that can effectively clamp and fix the inner and outer rings of bearings of different sizes, ensuring that they maintain a concentric circle design, thereby improving drilling accuracy and production efficiency, has become an urgent problem to be solved by those skilled in the art.

[0039] Reference Figure 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the clamping component 205 includes a movable block 2051 threadedly connected to the lead screw 201. A mounting plate 2052 is fixedly connected to the top of the movable block 2051. Movable grooves 2053 are formed on both sides of the top of the mounting plate 2052. A lead screw 2054 passes through the two movable grooves 2053. One end of the lead screw 2054 is fixedly connected to the inner wall of the movable groove 2053 via a bearing, and the other end of the lead screw 2054 extends through the mounting plate 205.

[0042] Specifically, rubber pads are bonded to the surfaces of the clamping plate 2056 and the positioning plate 2057 with adhesive.

[0043] Example 3

[0044] Reference Figure 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0045] Specifically, the drilling assembly 300 also includes a stabilizing rod 304 that is slidably connected to the inner cavity of the connecting seat 302. One end of the stabilizing rod 304 is fixedly connected to the surface of the motor 204. The stabilizing rod 304 and the connecting seat 302 are slidably engaged to prevent shaking during drilling and improve the roughness of the hole wall.

[0046] Specifically, the inner cavity of the movable block 2051 is provided with a threaded hole, and the lead screw 201 is threadedly connected to the inner cavity of the threaded hole. The movable block 2051 is slidably connected to the inner cavity of the movable groove 102. The threaded hole and the lead screw 201 are precisely matched, and the sliding connection of the movable block 2051 reduces frictional resistance.

[0047] Specifically, a gap is left between the bottom of the mounting plate 2052 and the top of the support plate 101. This gap ensures that there is no mechanical interference during the adjustment process.

[0048] Specifically, a gap is left between the drive gear 2059 and the through hole, and the output shaft of the second motor 20510 passes through the inner cavity of the through slot. The gap between the drive gear 2059 and the through hole, and the through slot design of the output shaft of the second motor 20510, realize power transmission in a compact structure.

[0049] In use, the start motor 204 drives the driving bevel gear 203 to rotate, which in turn drives the lead screw 201 to rotate via the driven bevel gear 202, causing the three clamping parts 205 to move synchronously. This allows for the adaptation of bearings of different sizes. The inner and outer rings of the bearing are then placed between the positioning plate 2057 and the clamping plate 2056. The second motor 20510 then drives the drive gear 2059 to rotate, which in turn drives all the driven gears 2055 to rotate synchronously via the double-sided gear 2058, causing the lead screw 2054 to drive the clamping plates 2056 to move in opposite directions. The motor moves to clamp the inner and outer rings of the bearing. The clamping force of the inner and outer rings is balanced by torque control to ensure strict concentricity. According to the drilling position requirements, the electric push rod 301 drives the connecting seat 302 to move linearly along the stabilizer rod 304, adjusts the position of the drilling machine 303, starts the drilling machine 303 and controls the feed rate to complete the drilling operation. After the processing is completed, the drilling machine 303 returns to its original position, the motor 20510 reverses to release the clamping part 205, and the bearing is taken out. The whole process is automatically completed by the preset program of the control system, realizing efficient and precise bearing drilling processing.
