Description

Technical Field

[0001] This application relates to the field of turbocharger assembly. Specifically, it relates to a clamp tightening and knocking mechanism. Background Art

[0002] A centrifugal compressor and a turbine are combined into a whole, called a turbocharger. The main difference between it and a gas turbine is that this unit does not have a combustion chamber and corresponding systems. The turbine uses the exhaust energy of a reciprocating internal combustion engine to work, and the compressed air provided by its centrifugal compressor is used as the charge of the reciprocating internal combustion engine. In a turbocharger, the compressor impeller and the turbine are assembled on the same rotating shaft, called the rotor. There are also seals and thrust washers, etc. that are placed on the same rotor shaft and rotate together.

[0003] During the assembly process of a turbocharger, a clamp is needed to fasten the workpiece. However, there is often a gap between the housing of the turbocharger and the clamp, which will affect the assembly effect. Utility Model Content

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Example 1

[0023] See also Figures 1-4, this embodiment provides a clamp tightening and knocking mechanism, which includes a workbench 1. The bottom of the workbench 1 is fixedly connected with support legs 2 to provide stable support and ensure that the workbench 1 does not displace or tilt during operation. The bottom of the workbench 1 is fixedly connected with a motor A11, and the output end of the motor A11 is fixedly connected with a processing seat 3, providing a basic platform for workpiece placement. The upper end of the workbench 1 is provided with a moving plate 4, and the upper end of the moving plate 4 is fixedly connected with a U-shaped plate 5. The upper end of the workbench 1 is fixedly connected with a cylinder C6, and the output end of the cylinder C6 is fixedly connected with a moving block 7. The moving block 7 is fixedly connected to the outer wall of the moving plate 4. The upper end of the workbench 1 is fixedly connected with a slide rail 10, and the moving plate 4 is slidably connected to the outer wall of the slide rail 10, providing a stable sliding path to ensure that the moving plate 4 can move smoothly on the workbench 1. The upper end of the moving plate 4 is provided with a knocking device. The knocking device includes a rotating ring 81, which is rotatably connected to the upper end of the moving plate 4. The outer wall of the rotating ring 81 is fixedly connected with a connecting rod A82. The other end of the connecting rod A82 is rotatably connected with a connecting rod B83 through a pin shaft. The other end of the connecting rod B83 is hinged with a knocking rod 84. The upper end of the moving plate 4 is fixedly connected with a fixed block 85. The knocking rod 84 is slidably connected to the middle of the fixed block 85. A spring 86 is movably sleeved on the outer wall of the knocking rod 84. A fixed ring 87 is fixedly sleeved on the outer wall of the knocking rod 84. The two ends of the spring 86 are respectively fixedly connected with the fixed block 85 and the fixed ring 87. The bottom of the moving plate 4 is fixedly connected with a motor B88. The outer wall of the motor B88 is fixedly connected with a connecting ring 810. The outer wall of the connecting ring 810 is fixedly connected with a拨动块89. The upper end of the connecting rod A82 is fixedly connected with a stop rod 811. The height of the stop rod 811 is higher than the height of the connecting ring 810 and the拨动块89.

[0024] It should be noted that there may be an error in the original text where "拨动块89" is not clearly defined. You may want to check and correct it if necessary.When the above-mentioned device is in specific use, first place the workpiece on the upper end of the processing seat 3. Then start the air cylinder C6, which makes the moving block 7 drive the moving plate 4 to slide on the outer wall of the slide rail 10 towards the workpiece to a suitable position, and then fix it through the fixing device. Next, put the clamp on the outer wall of the workpiece. At this time, the motor B88 can be started to drive the connecting ring 810 to rotate. Then the拨动块89 will rotate accordingly. When the拨动块89 rotates towards the stop lever 811 and makes contact, it continues to rotate, and then will drive the connecting rod A82 and the rotating ring 81 to rotate around the output shaft of the motor B88. Then the other end of the connecting rod A82 will drive the connecting rod B83 to rotate accordingly, and the other end of the connecting rod B83 will drive the knocking rod 84 to slide inwards at the middle of the fixing block 85, and at the same time will drive the fixing ring 87 to squeeze the spring 86. When the stop lever 811 rotates to the farthest distance from the fixing block 85, and then continues to rotate, the stop lever 811 will quickly reset from the other side of the connecting ring 810 under the action of the pulling force of the spring 86. Thus, under the action of the connecting rod A82 and the connecting rod B83, the knocking rod 84 quickly resets, thereby knocking on the outer wall of the clamp, making the clamp tightly adhere to the shell without gaps during vibration.

[0025] Embodiment 2

[0026] See Figures 1-4 , on the basis of Embodiment 1, a fixing device is provided on the upper end of the workbench 1. The fixing device includes an L-shaped plate 94, and the L-shaped plate 94 is fixedly connected to the upper end of the processing seat 3, which is convenient for adjusting the angle and position of the clamped workpiece. A threaded hole is opened on the side surface of the L-shaped plate 94, and a threaded rod 95 is arranged inside the threaded hole. One end of the threaded rod 95 close to the center of the processing seat 3 is fixedly connected to a connecting block 96, and the other side of the connecting block 96 is fixedly connected to a clamping block A97. The other end of the threaded rod 95 is fixedly connected to a rotating block 98. The upper end of the workbench 1 is fixedly connected with a mounting plate 91, and an air cylinder A92 is fixedly connected to the outer wall of the mounting plate 91. The output end of the air cylinder A92 is fixedly connected to a clamping block B93. The upper end of the U-shaped plate 5 is fixedly connected with an air cylinder B99, and the output end of the air cylinder B99 is fixedly connected to a clamping block C910.

[0027] When the above-mentioned equipment is used, when the movable plate 4 moves to the appropriate position, the cylinder B99 is started to drive the clamping block C910 to descend, so that the upper end of the workpiece can be fixed. Then the cylinder A92 is started to drive the clamping block B93 to approach the workpiece until it contacts the side of the workpiece. In addition, the rotating block 98 is rotated to drive the threaded rod 95 to rotate, and then the threaded rod 95 will rotate and move inward inside the threaded hole inside the L-shaped plate 94. Then, the clamping block A97 will be driven to approach the workpiece through the connecting block 96, so that the workpiece can be fixed. At the same time, the clamping block A97 driven by the threaded rod 95 is installed at the upper end of the processing seat 3. Therefore, when the motor A11 drives the processing seat 3 to rotate, it will also rotate accordingly, thereby changing the specific position of the clamping.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
