Description

Technical Field

[0001] The utility model relates to the technical field of spline connection, in particular to an automatic butt-jointed spline joint. Background Art

[0002] Spline joint is an important connection component widely used in the field of machinery. Its working principle is to achieve the transmission of torque and rotational motion through the tooth structure of the spline shaft and the spline sleeve. It has excellent torque transmission capacity. Due to the large tooth distribution and contact area of ​​the spline, it can withstand high torque loads. For example, in the transmission system of heavy machinery, the spline joint can ensure the stable transmission of powerful power and ensure the normal operation of the equipment.

[0003] During the spline connection process, the spline needs to be fixed. If the spline is not fixed during rotation, the spline or the connecting component will be detached. At the same time, the disassembly of the spline or the connecting component must also be taken into consideration. Therefore, an automatic docking spline joint is proposed. Utility Model Content

[0004] The utility model aims to provide an automatic butt-jointed spline joint to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides an automatically docking spline joint, comprising a spline, a spline joint is inserted at one end of the spline, an outer sliding sleeve of the spline joint is provided with a threaded extrusion shell, a plurality of connecting grooves are opened on the outer side of the spline joint, a hinge strip is hinged in the connecting groove, a hinge block is hinged at the other end of the hinge strip, a toothed extrusion plate is fixedly mounted on the hinge block, the spline joint sliding sleeve is provided with an extrusion ring, a plurality of first extrusion blocks are fixedly mounted on the extrusion ring, a second extrusion block and a second sliding block are fixedly mounted on the toothed extrusion plate, and a plurality of the toothed extrusion plates are provided with threaded fixing rings.

[0006] As a further improvement of the technical solution, the inner thread of the threaded extrusion shell is adapted to the threaded fixing ring, and the threaded extrusion shell is moved on the outside of the spline joint by rotating the threaded extrusion shell, while driving the extrusion ring to move.

[0007] As a further improvement of the technical solution, when the first extrusion block cooperates with the second extrusion block, when the extrusion ring drives the first extrusion block to move, the first extrusion block extrudes the second extrusion block, causing the toothed extrusion plate to shrink inward.

[0008] As a further improvement of the technical solution, a plurality of first sliding blocks are fixedly installed on the inner side of the extrusion ring. The first sliding blocks are slidably installed in the connecting grooves. At the same time, the first sliding blocks do not interfere with the hinge strips. The first sliding blocks limit the extrusion ring.

[0010] As a further improvement of the technical solution, the toothed extrusion plate is provided with teeth, and the teeth are adapted to the splines, so that the toothed extrusion plate fixes the splines.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the automatically docking spline joint, a threaded extrusion shell is set up, and the threaded extrusion shell is rotated to drive the extrusion ring to move, so that the first extrusion block on the extrusion ring squeezes the second extrusion block on the toothed extrusion plate, so that the toothed extrusion plate slides on the threaded fixing ring, so that multiple toothed extrusion plates squeeze and fix the spline, avoiding the spline or connecting parts from detaching, and also facilitating the staff to disassemble the spline or connecting parts.

[0025] The spline joint 2 is provided with an extrusion ring 3 on which a plurality of first extrusion blocks 32 are fixedly mounted. A second extrusion block 33 and a second sliding block 34 are fixedly mounted on the toothed extrusion plate 24. The extrusion ring 3 drives the first extrusion block 32 to move so that the first extrusion block 32 extrudes the second extrusion block 33, thereby enabling the toothed extrusion plate 24 to extrude and fix the spline 1. A plurality of first sliding blocks 31 are fixedly mounted on the inner side of the extrusion ring 3. The first sliding block 31 is slidably mounted in the connecting groove 21. The extrusion ring 3 can be limited by the first sliding block 31 to prevent the extrusion ring 3 from deflecting when moving. At the same time, in the connecting groove 21, the first sliding block 31 is fixedly mounted on the inner side of the extrusion ring 3. The movable block 31 and the hinge strip 22 do not interfere with each other. The outer sliding sleeve of the spline joint 2 is provided with a threaded extrusion shell 4, and multiple toothed extrusion plates 24 are provided with a threaded fixing ring 5.

The toothed extrusion plate 24 slides on the threaded fixing ring 5 through the second sliding block 34, and the second sliding block 34 limits the threaded fixing ring 5. The inner thread of the threaded extrusion shell 4 is adapted to the threaded fixing ring 5.

[0026] By rotating the threaded extrusion shell 4, the threaded extrusion shell 4 is moved on the outside of the spline joint 2, and the extrusion ring 3 is driven to move at the same time.
