Description

Technical Field

[0001] The present invention relates to the technical field of bearing positioning, and in particular to a large-scale bearing rapid positioning and locking mechanism. Background Art

[0002] Due to the long processing route of bearings, the traditional processing method of manual alignment and magnetic chuck clamping consumes a lot of manpower and time, resulting in long waiting times for equipment and low actual equipment utilization. This is particularly disadvantageous in terms of rapid response such as new product development and small batch conversion. Under the conditions of maintaining the existing equipment scale and staffing, this processing method has increasingly become a major factor restricting the development of enterprises, which is specifically manifested in the following aspects:

[0003] 1. The traditional method is time-consuming and the equipment utilization rate is low.

[0004] 2. Tightening and loosening the magnetic suction cup requires bending over, which can easily cause accidental collision and injury.

[0005] 3. Once a manual operation error occurs, such as the magnetic chuck is not tightened or is not tightened properly, it will cause the workpiece to shift during processing, resulting in unqualified products.

[0006] 4. The traditional positioning method has poor consistency. As the workpiece circulates, its positioning accuracy continues to decline, increasing the risk of non-conformity.

[0007] 5. High production costs and low competitiveness.

[0008] On the other hand, in recent years, the country has implemented a series of favorable policies and subsidies for the new energy industry, leading to an increasing number of companies entering the wind power industry. Competition within the industry has also gradually evolved towards the update and application of new equipment, new methods, and new technologies. Therefore, solving the problems of rapid positioning and positioning consistency during the production process has become a new challenge to reduce production costs and improve efficiency. To this end, we have proposed a rapid positioning and locking mechanism for large bearings. Summary of the Invention

[0009] In view of the deficiencies of the prior art, the present invention provides a large bearing rapid positioning and locking mechanism, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a large-scale bearing rapid positioning and locking mechanism, comprising a workbench and a bearing arranged above the workbench, an air pipe and an auxiliary pad fixedly installed on the top of the workbench, an inflation port connected to the air pipe provided on the workbench, a positioning screw provided at the bottom of the bearing, four zero-point bases fixedly installed on the top of the workbench, a pneumatic clamp contained inside the zero-point base, the pneumatic clamp is opened and closed by air pressure, the air pipe is connected to the pneumatic clamp, and the positioning screw is located directly above the zero-point base.

[0011] As a preferred technical solution of the present invention, eight auxiliary pads are provided, and the eight auxiliary pads are evenly arranged on the top of the workbench in a ring shape.

[0012] As a preferred technical solution of the present invention, a base positioning hole is opened on the zero point base, the positioning screw is adapted to the base positioning hole, and one end of the positioning screw is provided with a conical structure.

[0013] As a preferred technical solution of the present invention, the position of the zero point base on the workbench is determined by a positioning plate, and four zero point bases are evenly arranged in a ring shape on the top of the workbench.

[0014] As a preferred technical solution of the present invention, the bearing is threadedly connected to the positioning screw.

[0015] As a preferred technical solution of the present invention, the positioning screw is movably connected to the zero point base.

[0016] As a preferred technical solution of the present invention, the trachea is arranged in a ring structure.

[0017] As a preferred technical solution of the present invention, the workbench and the zero-point base are detachably connected.

[0018] Beneficial effects of the present invention:

[0019] One end of the positioning screw thread is installed on the bearing. The positioning screw is connected to the bearing thread for easy disassembly. The port on the other side is conical in design and is used to insert into the base positioning hole. It can be easily installed by roughly aligning it with the zero point base positioning hole.

[0020] The position of the zero point base on the workbench is determined by the positioning disk, and then the inner hole of the positioning disk is punched to determine its concentricity with the turntable. A pneumatic clamp is set inside the zero point base, and the air flow is delivered to the pneumatic clamp through the air pipe. The opening and closing of the pneumatic clamp is controlled by air pressure. After the air source is connected, the air flow is delivered to the pneumatic clamp through the air pipe, and the pressure pushes the pneumatic clamp to loosen the clamp, so that the positioning screw can enter the base positioning hole on the zero point base; after the air source is cut off, the pneumatic clamp is clamped to fix the position of the positioning screw and the bearing. The auxiliary pads are evenly placed between the four zero point bases to share the weight of the bearing.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-4 A large bearing quick positioning and locking mechanism includes a workbench 3 and a bearing 6 arranged above the workbench 3. An air pipe 2 and an auxiliary pad 4 are fixedly installed on the top of the workbench 3. An inflation port connected to the air pipe 2 is provided on the workbench 3. There are eight auxiliary pads 4, and the eight auxiliary pads 4 are evenly arranged in a ring shape on the top of the workbench 3.

[0029] A positioning screw 1 is provided at the bottom of the bearing 6. The bearing 6 and the positioning screw 1 are threadedly connected. One end of the thread of the positioning screw 1 is mounted on the bearing 6. The positioning screw 1 is threadedly connected to the bearing 6 for easy disassembly.

[0030] A base positioning hole is provided on the top of the zero point base 5 , and the positioning screw 1 is adapted to the base positioning hole. One end of the positioning screw 1 is provided with a conical structure, and the positioning screw 1 can enter the base positioning hole on the zero point base 5 .

[0031] Four zero-point bases 5 are fixedly mounted on the top of the workbench 3 , and the workbench 3 and the zero-point bases 5 are detachably connected.

[0032] The position of the zero point base 5 on the workbench is determined by a positioning plate, and four zero point bases 5 are evenly arranged on the top of the workbench 3 in a ring shape.

[0033] The zero-point base 5 contains a pneumatic clamp, which opens and closes via air pressure. Air pipe 2 is connected to the pneumatic clamp, which is arranged in a ring-shaped structure. Positioning screw 1 is located directly above the zero-point base 5 and is movably connected to the zero-point base 5. Air is supplied to the pneumatic clamp via air pipe 2, and air pressure controls its opening and closing. When the air source is connected, air pipe 2 supplies air to the pneumatic clamp, and the pressure pushes the pneumatic clamp to loosen the clamp, allowing positioning screw 1 to enter the base positioning hole on the zero-point base 5. When the air source is disconnected, the pneumatic clamp tightens, securing the position of positioning screw 1 and bearing 6.

[0034] Working principle: One end of the thread of the positioning screw 1 is installed on the bearing 6. The positioning screw 1 is threadedly connected to the bearing 6 for easy disassembly. The port on the other side is tapered and used to insert into the base positioning hole. It can be easily installed by roughly aligning it with the zero point base positioning hole.

[0035] The position of the zero point base 5 on the workbench 3 is determined by the positioning disk, and then the inner hole of the positioning disk is punched to determine its concentricity with the turntable. A pneumatic clamp is provided inside the zero point base 5, and the air flow is delivered to the pneumatic clamp through the air pipe 4. The opening and closing of the pneumatic clamp is controlled by air pressure. After the air source is connected, the air flow is delivered to the pneumatic clamp by the air pipe 4, and the pressure pushes the pneumatic clamp to loosen the clamp, so that the positioning screw 1 can enter the base positioning hole on the zero point base 5; after the air source is cut off, the pneumatic clamp is clamped to fix the position of the positioning screw 1 and the bearing 6, and the auxiliary pads are evenly placed between the four zero point bases 5 to share the weight of the bearing 6.
