Description

Technical Field

[0001] The utility model relates to the technical field of riveting machines, and more particularly to a semi-automatic bidirectional bearing riveting machine. Background Art

[0002] The riveting machine is a new type of riveting equipment developed based on the principle of cold rolling. It refers to mechanical equipment that can rivet objects together with rivets. Riveting is a riveting method that uses the static pressure generated by the riveting machine to upset the rivet rod to form an upset head. Existing bearings and rotors are usually riveted together by a bearing riveting press. When using the existing manual bearing riveting press, the operator needs to first install the bearing to the corresponding position, and then manually press the shaft into the bearing. Therefore, only one side of the bearing can be pressed in at a time, and a rotor bearing needs to be riveted twice, resulting in low efficiency. At the same time, the riveting position is completely manually positioned by the operator, which will cause a certain error in the coaxiality between the bearing and the shaft during riveting, and there is a risk of injury. The operator's hands are completely in contact with the press and tooling during operation, and there is a certain risk of injury.

[0003] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0019] In the description of the present invention, it should be noted that the terms "length", "width", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate that the device referred to must have a specific orientation or operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] Semi-automatic bidirectional bearing riveting press, such as Figure 1 As shown, it includes a workbench 1, a mounting table 2 for placing a rotor 10 is provided on the workbench 1, a cylinder 3 is provided on the workbench 1, a fixed sleeve 12 is provided on the workbench 1, and a movable sleeve 4 for installing a bearing is provided on the movable end of the cylinder 3, and the fixed sleeve 12 and the movable sleeve 4 are respectively arranged on both sides of the mounting table 2, and two vertically arranged positioning pieces 5 are provided on the mounting table 2, and a space for accommodating the installation of the rotor 10 is formed between the two positioning pieces 5, and a positioning groove is provided on the positioning piece 5. The design of the positioning piece 5 and the positioning groove makes it convenient for the operator to place the rotor 10, and the positioning groove can pre-position the rotor 10, ensuring that the bearing can be smoothly sleeved on the rotor 10. By providing the mounting table 2, the fixed sleeve 12 and the movable sleeve 4, the operator only needs to place the rotor 10 on the mounting table 2 On, the two bearings are respectively embedded in the fixed sleeve 12 and the movable sleeve 4. Then the operator can press the power button, the cylinder 13 starts to run and drives the movable sleeve 4 toward the fixed sleeve 12, thereby completing the operation of the two bearings into the shaft at the same time. Through the above operation, the efficiency of installing the bearings is improved. The present device can realize riveting two bearings at a time to complete the assembly of the bearings on both sides of the rotor 10. At the same time, compared with the old device that manually adjusts the pressing position of the shaft, after the bearings of the present device are placed in the sleeve, it can ensure that the two bearings are coaxial with the rotor 10, and the riveting position is more accurate. Compared with the old device that is completely manual riveting and the operator directly contacts, the present device is semi-automatic. The operator only needs to press the start switch, and the two cylinders will fix the rotor 10 and rivet the bearings. The operator does not touch the device, which improves the safety of the equipment.

[0023] The mounting platform 2 is slidably connected to the workbench 1. Specifically, a slide rail 6 is provided on the workbench 1, and a slide groove 7 for accommodating the embedding of the slide rail 6 is provided on the bottom surface of the mounting platform 2. Since the mounting platform 2 can slide, the operator can adjust the distance from the mounting platform 2 to the fixed sleeve 12 when performing shaft insertion operations on bearings and rotors 10 of different models, thereby ensuring the efficiency of the operation. The setting of the slide groove 7 and the slide rail 6 not only ensures the stable sliding of the mounting platform 2, but also plays a certain guiding role in the sliding of the mounting platform 2, thereby further improving the stability of the mounting platform 2.

[0024] Furthermore, a clamping assembly is provided on the mounting table 2, which includes a cylinder 2 8 and a clamping block 9 located at the movable end of the cylinder 2 8. The cylinder 2 8 is used to drive the clamping block 9 to press against the rotor 10. By setting the cylinder 2 8 and the clamping block 9, the operator can press the power button first when performing the shaft insertion operation, so that the cylinder 2 8 pushes the clamping block 9 to descend and press against the rotor 10. At this time, the clamping block 9 and the positioning piece 5 respectively clamp the two sides of the rotor 10, so that the rotor 10 will not shake when the bearings on both sides are subsequently installed on the rotor 10, thereby further improving the stability of the rotor 10.

[0025] A limit block 11 is provided on the workbench 1 and the limit block 11 is located on the side of the slide rail 6 away from the fixed pipe sleeve 12. By setting the limit block 11, the limit block 11 can prevent the mounting platform 2 from accidentally sliding out of the slide rail 6 during operation, thereby increasing the safety of operation. At the same time, it also avoids the mounting platform 2 from tipping over, causing damage to the cylinder 2 8 and the clamping block 9, thereby extending the service life of the equipment. Furthermore, a compression spring 13 is provided between the fixed pipe sleeve 12 and the mounting platform 2. When the compression spring 13 is in a non-compressed state, the mounting platform 2 is pressed against the limit block 11. By setting the compression spring 13, after the equipment is assembled once, the mounting platform 2 will rebound and press against the limit block 11 under the spring action of the compression spring 13, thereby making it convenient for the operator to take the rotor 10, and at the same time improving the connection strength between the limit block 11 and the mounting platform 2, thereby ensuring the stability of the equipment.

[0026] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
