Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a fixing device for parts. Background Art

[0002] In the field of machinery, piston rings are a common component that is installed on the piston to seal the gap between the piston and the cylinder wall, prevent gas and oil leakage, and play a certain role in heat transfer and lubrication. Piston rings are usually made of metal materials, have a certain elasticity and hardness, and can work in high temperature and high pressure environments. When installing the piston ring, it needs to be placed in the ring groove of the piston and its opening is staggered at a certain angle to maintain the sealing performance of the piston ring.

[0003] In the traditional piston ring removal process, due to the close fit between the piston ring and the piston, the piston needs to be fixed during the removal process, and then the piston ring needs to be removed from the piston mechanically or manually. The fixing of the piston is a key step in the removal process, and it is necessary to ensure that the piston does not slide or rotate during the removal process to avoid damage to the piston ring. However, some piston fixing devices in the prior art are only suitable for pistons of specific sizes or types. For pistons of different sizes or types, the fixing devices need to be replaced or adjusted, which reduces work efficiency. Therefore, a new type of component fixing device is needed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0019] Embodiment: A fixing device for a component, such as Figure 1-Figure 3 As shown, it includes a base 1, a support column 2, a rotating mechanism 3 and a fixing mechanism 4. The support column 2 is arranged on the top of the base 1. The rotating mechanism 3 for changing the position of the piston is rotatably arranged on the support column 2. Four fixing mechanisms 4 for fixing the piston are arranged on the rotating mechanism 3.

[0020] like Figure 1 and Figure 2 As shown, the rotating mechanism 3 includes an annular rotating shaft 31, a turntable 1 32 and a turntable 2 33. The annular rotating shaft 31 is fixedly connected to the upper part of the support column 2 by welding. The turntable 1 32 is rotatably provided on the upper part of the annular rotating shaft 31, and the turntable 2 33 is rotatably provided on the lower part of the annular rotating shaft 31. The turntable 2 33 is located below the turntable 1 32.

[0021] like Figure 1-Figure 3 As shown, the fixing mechanism 4 includes a connecting shell 41, a screw rod 42, a bevel gear 43, an arc-shaped clamping plate 44 and a motor 45. Four connecting shells 41 are fixedly connected between the turntable 1 32 and the turntable 2 33 by welding. Four screw rods 42 are rotatably arranged on the inner side walls of the connecting shells 41. The screw rods 42 are distributed in a cross shape. The ends of the screw rods 42 away from the connecting shells 41 are provided with bevel gears 43. The four bevel gears 43 are continuously meshed with each other adjacent to each other. Arc-shaped clamping plates 44 are rotatably arranged on the screw rods 42. The turntable 1 32 is provided with through holes with the same number of arc-shaped clamping plates 44. The arc-shaped clamping plates 44 are all slidably connected to the turntable 1 32 through the through holes. Four motors 45 are installed on the turntable 2 33. The output shafts of the motors 45 all pass through the connecting shells 41 and are connected to the screw rods 42 adjacent to them.

[0022] When in use, the staff places the piston whose piston ring is to be removed on the inner side of the nearest arc-shaped clamping plate 44, starts all the motors 45, and the output shaft of the motor 45 drives the screw rod 42 connected thereto to rotate, thereby driving the arc-shaped clamping plate 44 on the screw rod 42 to move inward. At the same time, due to the meshing action between the bevel gears 43, the remaining three adjacent screw rods 42 are driven to rotate together, thereby driving the arc-shaped clamping plates 44 connected thereto to move inward. When the four arc-shaped clamping plates 44 move inward at the same time until they are in close contact with the piston, all the motors 45 are turned off, and the arc-shaped clamping plates 44 clamp and fix the piston to ensure that the piston does not slide or rotate during the removal process, which is convenient for the staff to remove the piston ring on the piston. The arc-shaped design of the clamping plate and its ability to adjust the size it accommodates when moving on the screw rod 42 make the fixing mechanism 4 suitable for pistons of different sizes and types, reducing the number of replacements or adjustments, improving work efficiency, and having a wide range of applicability, and can be used to fix other components. After the staff has finished disassembling the piston ring of one piston, they can quickly move the next empty clamping plate to the side of the staff by rotating the turntable 32 to fix the next piston, thereby maintaining the continuity of work and improving work efficiency.

[0023] like Figure 1 and Figure 2 As shown, it also includes a handle 5, and four handles 5 are arranged on the top of the turntable 1 32.

[0024] like Figure 1 and Figure 3 As shown, a rubber pad 6 is also included, and a rubber pad 6 is arranged on the inner side of the arc-shaped clamping plate 44.

[0025] like Figure 1 and Figure 2 As shown, an anti-slip cover 7 is also included, and the handle 5 is provided with an anti-slip cover 7.

[0026] The setting of the handle 5 enables the staff to easily rotate the turntable 32, improving the convenience of the device. The setting of the rubber pad 6 can improve the clamping stability of the clamping plate on the piston by increasing the friction of the contact surface, and can provide buffer protection for the piston to prevent the piston from deformation and damage. The setting of the anti-slip sleeve 7 can increase the friction of the gripping part of the handle 5, prevent hand slippage, and improve the stability of operation.
