DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] This embodiment is a connecting rod design, processing and fixing device.

[0024] like Figure 1-4As shown, it includes a base 1, a column 2 is fixedly installed in the middle of the outer surface of the upper end of the base 1, an oil supply valve 7 and an oil return valve 8 are fixedly installed on the lower part of the outer surface of one side of the column 2, a limit support plate 3 is fixedly installed on the outer wall of the upper part of the column 2, and a guide ring 4 is fixedly installed on the front, rear, left and right ends of the upper part of the column 2, a support rod 5 is arranged in the guide ring 4, a through groove 14 is opened on the outer surface of one side of the support rod 5, a limit block 15 and a compression spring 16 are arranged in the through groove 14, and the limit block 15 passes through the through groove 14, an oil chamber 9 is opened inside the column 2, a fixed sealing ring 13 is fixedly installed on the end of the inner wall of the guide ring 4 away from the oil chamber 9, and a movable sealing ring 17 is fixedly installed on the outer wall of the support rod 5 close to the oil chamber 9.

[0025] An arcuate surface 6 is provided at one end of the support rod 5 away from the movable sealing ring 17; the outer wall of the support rod 5 is slidably connected to the guide collar 4; the limit block 15 passes through the through groove 14 and is fixed inside the guide collar 4, and the compression spring 16 is located on one outer surface of the limit block 15; the outer surface of one end of the compression spring 16 is fixedly connected to the outer surface of one side of the through groove 14, and the outer surface of the other end of the compression spring 16 is fixedly connected to the outer surface of one side of the limit block 15; the support rod 5 is elastically connected to the outer surface of one side of the limit block 15 through the compression spring 16, and the inner cavity of the guide collar 4 is connected to the oil chamber 9.

[0026] It should be noted that the utility model is a connecting rod design and processing fixing device. When the connecting rod needs to be fixed, two sets of fixing devices are needed to fix it because there are two holes at both ends of the connecting rod. The oil supply valve 7 and the oil return valve 8 are connected to an external oil supply pump. At this time, the support rod 5 is located in the guide collar 4, and the connecting rod is sleeved on the outer wall of the upper part of the column 2. The connecting rod is supported by the limit support plate 3. After that, the oil supply pump supplies oil to the oil chamber 9 through the oil supply valve 7. The hydraulic oil enters the guide collar 4 to squeeze the support rod 5, and the support rod 5 drives the mobile sealing ring 17 to move along the guide Move toward the inner wall of the collar 4, and relative movement occurs between the outer wall of the support rod 5 and the fixed sealing ring 13. The movable sealing ring 17 and the fixed sealing ring 13 are provided to play a sealing role. One end of the support rod 5 moves out to the outside of the guide collar 4 and is fixed on the inner wall of the connecting rod hole, so that it is suitable for connecting rods of different apertures and improves applicability. When one end of the support rod 5 moves out of the guide collar 4, the support rod 5 squeezes the compression spring 16 on one side of the limit block 15. When the oil returns, the support rod 5 is reset due to the reset effect of the compression spring 16.

[0027] It should be noted that, in this article, relational terms such as first and second (number one, number two), etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
