Description

Technical Field

[0001] The utility model relates to the technical field of coupling extrusion, and more specifically, to a coupling rubber ring extrusion device for a grease pump. Background Art

[0002] The main purpose of the grease pump coupling rubber ring extrusion device is to ensure a tight and reliable connection between the grease pump and the coupling, prevent grease leakage, and ensure effective power transmission. Therefore, extrusion is of great use.

[0003] In existing public documents, patent publication number CN209483829U discloses a coupling device with good buffering effect. This technology uses the elastic force of a spring to slow down the force generated by the displacement of the first limit block and the second limit block, thereby slowing down the force generated by the axial displacement of the driving shaft and the driven shaft. Through the action of the spring and two elastic rubber rings, the force generated by the axial displacement of the driving shaft and the driven shaft is offset, thereby further enhancing the buffering effect of the driving shaft and the driven shaft, avoiding damage to the coupling, and thus improving the performance of the coupling. However, this coupling rubber ring extrusion device has the following defects:

[0004] Although the coupling rubber ring extrusion device can achieve extrusion sealing of the grease pump coupling during sealing extrusion, it is difficult to lock the various docking locking positions according to the specified position during the extrusion process. This leads to extrusion offset during the sealing process, making it difficult to stably achieve extrusion sealing of the grease pump coupling rubber ring, and the extrusion accuracy is poor.

A valve is fixedly connected to one side of the sealing disk near its center point, and the valve and the sealing disk are connected.

[0008] According to the technical solution, when in use, the extrusion positioning strip slides and rotates on the outer wall of the ring rail, the shaft flange supports the pillar, and the extrusion positioning strip drives the positioning outer block to move in contact with the right side of the sealing disk. When there is a large gap between the right side of the sealing disk and the positioning outer block, the nut and the extrusion bolt are threadedly engaged and locked, so that the sealing disk can be squeezed onto the sealing ring for sealing.

The outer wall of the ring rail 4 and the inner wall of the extruded positioning strip 5 are both smooth surfaces, and the ring rail 4 and the extruded positioning strip 5 are both made of stainless steel. The positioning inner block 6 is slidingly connected to the shaft flange 2, and the vertical cross-section shapes of the positioning inner block 6 and the positioning outer block 7 are both rectangular.

[0023] In this technical solution, as shown in the attached Figure 3-4 As shown, a support block 11 is fixedly connected to the outer wall of the extrusion positioning strip 5 near the position of the ring rail 4, and a reinforcement column 13 is fixedly connected to one side of the support block 11; a gripping sleeve 12 is bonded to the outer wall of the reinforcement column 13, and a limit block 14 is installed at one end of the reinforcement column 13 to facilitate hand gripping on the outer wall of the gripping sleeve 12, and the limit block 14 limits the left side of the hand. In this way, when the gripping sleeve 12 is moved, the gripping sleeve 12 drives the reinforcement column 13, and the reinforcement column 13 causes the support block 11 to move, making it easier to grip and rotate. A sealing ring 15 is fixedly connected to the inner wall of the shaft connecting tube 1, and the sealing ring 15 is made of rubber material; the vertical cross-section of the sealing ring 15 is annular, so that the sealing disk 8 can be squeezed on the sealing ring 15 for sealing, achieving a stable sealing operation.

When there is a large gap between the right side of the sealing disk 8 and the positioning outer block 7, the nut 10 is rotated by a wrench, and the threaded engagement and locking between the nut 10 and the extrusion bolt 9 can make the sealing disk 8 squeezed on the sealing ring 15 for sealing. At the same time, the sealing disk 8 and the shaft connecting tube 1 are sealed and connected, and the shaft connecting tube 1 supports the shaft connecting flange 2. In this way, the shaft connecting tube 1 and the sealing disk 8 can be accurately positioned and extruded between the positioning outer block 7 and the positioning inner block 6, the extrusion is more precise, and after the valve 16 is opened, the lubricating grease inside the sealing disk 8 can be delivered.

The arc frame 18 supports the reinforcement connecting frame 19, and the connecting frame 19 provides reinforcement force to the reinforcement frame 20.
