Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a fixing fixture for a sealing ring forging. Background Technology

[0002] Forged sealing rings are ring-shaped parts manufactured by forging. They are mainly used in mechanical devices to prevent fluid (liquid, gas) leakage or the intrusion of external impurities. They are widely used in aerospace, petrochemical, nuclear power, automotive, compressor and other fields. Their performance and quality directly affect the sealing performance, reliability and service life of the equipment. When processing the surface of the forged sealing rings, it is necessary to fix their position with a fixing fixture.

[0003] Currently, in the processing of sealing ring forgings, the commonly used fixing fixtures typically employ a four-way clamping method to ensure the stability of the forgings during processing. However, such fixtures have significant drawbacks: achieving four-way fixation often relies on the coordinated drive of two or more power devices, which not only significantly increases equipment costs but also requires precise control of multiple devices to operate synchronously at the same speed. The operation process is cumbersome and complex, and prone to errors. Based on this, this application proposes a fixing fixture for sealing ring forgings. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing fixture for sealing ring forgings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fixing fixture for a sealing ring forging includes a platform, the upper half of which has a storage cavity, a rotatable cylindrical transmission gear is provided in the middle of the storage cavity, first rack plates are provided on both the front and rear sides of the upper half of the transmission gear, and second rack plates are provided on both the left and right sides of the lower half of the transmission gear. The top of the platform has four slots in a circular array that communicate with the storage cavity. L-shaped movable plates are fixedly installed on the top of the two first rack plates and the two second rack plates at the ends away from the transmission gear, and the vertical parts of the four movable plates are respectively located in the four slots. The tops of the vertical parts of the four movable plates extend out of the slots, and the tops of the vertical parts of the four movable plates are at the same horizontal height.

[0006] Furthermore, two sets of first positioning rods are fixedly installed on both the front and rear sides of the inner wall of the storage cavity. The two sets of first positioning rods are located on both sides of the upper half of the transmission gear, and there are two first positioning rods in each set. Two first rack plates are movably sleeved on the two sets of first positioning rods. Two second positioning rods are fixedly installed on both the left and right sides of the inner wall of the storage cavity. The two sets of second positioning rods are located on both sides of the lower half of the transmission gear, and there are two second positioning rods in each set. Two second rack plates are movably sleeved on the two sets of second positioning rods.

[0007] Furthermore, a bottom groove is provided at the bottom of the shelf, and a motor is fixedly installed at the center of the top of the inner wall of the groove. The output end of the motor extends into the shelf cavity and is fixedly connected to the shaft at the bottom of the transmission gear.

[0008] Furthermore, both the first and second rack plates have teeth on their sides near the transmission gear, and the teeth on the side of the first rack plate mesh with the side wall of the upper part of the transmission gear, while the teeth on the side of the second rack plate mesh with the side wall of the lower part of the transmission gear.

[0009] Furthermore, the top of the storage platform has an X-shaped storage slot, and a lifting frame adapted to its size is installed in the storage slot. Hydraulic rods are fixedly installed at the four corners of the bottom of the storage cavity. The telescopic ends of the four hydraulic rods extend to the four ends of the storage slot, and the telescopic ends of the four hydraulic rods are fixedly connected to the bottom of the four ends of the lifting frame.

[0010] Furthermore, semi-cylindrical limiting plates are fixedly installed at both ends of the movable plate near the center side of the shelf, and the bottom of the limiting plates is flush with the top of the shelf.

[0011] The beneficial effects of this utility model are:

[0012] By starting the motor, the transmission gear rotates within the storage cavity. The clockwise rotation of the transmission gear simultaneously engages and rotates the first and second rack plates, causing them to move relative to each other. This moves the four moving plates simultaneously towards the center of the four slots on the top of the storage platform, thus clamping and fixing the sealing ring forging placed on the top of the platform. To release the forging, simply control the motor to rotate the transmission gear counterclockwise. Compared to common positioning mechanisms, this method is simple and convenient to operate. Furthermore, a single motor can move four moving blocks simultaneously, precisely clamping the sealing ring forging at the center of the top of the platform, thus improving the efficiency of forging fixation.

[0013] When removing the sealing ring forging, the four hydraulic rods are controlled to extend synchronously, causing their telescopic ends to push the four ends of the lifting frame upwards respectively. Since the lifting frame has an X-shaped structure, it can flexibly adapt to sealing ring forgings of different sizes and provide stable support. This design allows the bottom of the sealing ring forging to separate from the top surface of the platform, making it easy to remove it from the platform. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-7This utility model provides a technical solution: a fixing fixture for a sealing ring forging, including a platform 1. The upper half of the platform 1 has a storage cavity. A rotatable cylindrical transmission gear 2 is arranged in the middle of the storage cavity. First rack plates 4 are arranged on both the front and rear sides of the upper half of the transmission gear 2, and second rack plates 6 are arranged on both the left and right sides of the lower half of the transmission gear 2. The top of the platform 1 has four slots 8 arranged in a circular array that communicate with the storage cavity. The tops of the two first rack plates 4 and the two second rack plates 6 are fixedly installed at the ends away from the transmission gear 2. There are L-shaped movable plates 9, and the vertical parts of the four movable plates 9 are respectively located in the four slots 8. The tops of the vertical parts of the four movable plates 9 extend out of the slots 8, and the tops of the vertical parts of the four movable plates 9 are at the same horizontal height. The rotation of the transmission gear 2 drives the two first rack plates 4 and the two second rack plates 6 to move relative to each other at the same time, so that the vertical parts of the four movable plates 9 move towards the center of the platform 1 in the corresponding slots 8, thereby quickly completing the fixed clamping of the sealing ring forging at the top of the platform 1, and can press and fix the position of the forging at the center of the top of the platform 1.

[0025] like Figure 3 and Figure 5 As shown, two sets of first positioning rods 3 are fixedly installed on both the front and rear sides of the inner wall of the storage cavity. The two sets of first positioning rods 3 are located on both sides of the upper half of the transmission gear 2, and there are two first positioning rods 3 in each set. Two first rack plates 4 are movably sleeved on the two sets of first positioning rods 3. Two second positioning rods 5 are fixedly installed on both the left and right sides of the inner wall of the storage cavity. The two sets of second positioning rods 5 are located on both sides of the lower half of the transmission gear 2, and there are two second positioning rods 5 in each set. Two second rack plates 6 are movably sleeved on the two sets of second positioning rods 5. Through the first positioning rods 3 and the second positioning rods 5, the movement direction of the first rack plates 4 and the second rack plates 6 can be restricted, making the first rack plates 4 and the second rack plates 6 more stable during movement.

[0026] like Figure 4 and Figure 6 As shown, the bottom of the storage platform 1 has a bottom groove, and a motor 7 is fixedly installed at the center of the top of the inner wall of the bottom groove. The output end of the motor 7 extends into the storage cavity and is fixedly connected to the shaft at the bottom of the transmission gear 2. The motor 7 can provide power for the rotation of the transmission gear 2.

[0027] like Figure 3 and Figure 4As shown, the first rack plate 4 and the second rack plate 6 are both provided with teeth on the side near the transmission gear 2. The teeth on the side of the first rack plate 4 mesh with the side wall of the upper part of the transmission gear 2, and the teeth on the side of the second rack plate 6 mesh with the side wall of the lower part of the transmission gear 2. By rotating the transmission gear 2, the two first rack plates 4 and the two second rack plates 6 can be driven to move relative to each other at the same time, thereby driving the four moving plates 9 to move in the corresponding slots 8.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the top of the storage platform 1 is provided with an X-shaped storage slot 11. A lifting frame 12 adapted to its size is provided in the storage slot 11. Hydraulic rods 13 are fixedly installed at the four corners of the bottom of the storage cavity. The telescopic ends of the four hydraulic rods 13 extend to the four ends of the storage slot 11, and the telescopic ends of the four hydraulic rods 13 are fixedly connected to the bottom of the four ends of the lifting frame 12. By controlling the synchronous extension of the four hydraulic rods 13, their telescopic ends push the four ends of the lifting frame 12 upward. After the lifting frame 12 moves out of the storage slot 11, it can lift the sealing ring forging and separate its bottom from the top surface of the storage platform 1, so as to facilitate the removal of the forging from the storage platform 1.

[0029] like Figure 1 and Figure 7 As shown, semi-cylindrical limiting plates 10 are fixedly installed at both ends of the movable plate 9 near the center side of the platform 1, and the bottom of the limiting plate 10 is flush with the top of the platform 1. The limiting plates 10 on the side of the movable plate 9 facilitate the clamping of the outer wall of sealing ring forgings of different sizes. The clamping stability is high and it is not easy to cause extrusion marks on the outer wall of the forging.
