Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is the structure schematic diagram of the utility model, fig. 2 is the structure schematic diagram of the axis body of the utility model, fig. 3 is the structure schematic diagram of the positioning mechanism of the utility model, fig. 4 is the structure schematic diagram of the clamp splice of the utility model.

The utility model provides an adjustable axle, includes

axis body

1, and 1 one end of axis body is equipped with screw thread 2, be equipped with the slide rail 3 that is used for cooperating the downthehole spout of gear shaft on the axis body 1, install two splint 4 on the axis body 1, be fixed with clamp splice 5 on the 4 medial surfaces of splint, be equipped with several location punch combination 6 on the axis body 1, location punch combination 6 comprises the locating hole of several centre of a circle range on a straight line, installs the positioning mechanism 7 that is used for inserting the locating hole on the 4 lateral surfaces of splint, is equipped with the oiling pore in the clamp splice 5. The positioning mechanism 7 is composed of a cylinder 71, a rod 72 and a spring 73, the cylinder 71 is fixed on the clamping plate 4, the rod 72 penetrates through the cylinder 71, and the spring 73 is connected between the cylinder 71 and the rod 72. Two symmetrical positioning mechanisms 7 are arranged on the clamping plate 4, and each positioning mechanism 7 corresponds to one group of positioning hole groups 6. A plurality of oil outlets 8 are distributed on the end surface of the clamping block 5, and the oil outlets 8 are communicated with the oil injection pore channel. And a silica gel layer is fixed on the end surface of the clamping block 5.

Referring to fig. 1, 2, 3 and 4, two clamp plates 4 and a gear are sleeved on the shaft 1, the gear is located between the two clamp plates 4, and two clamp blocks 5 fixed to the clamp plates 4 are attached to the left and right end faces of the gear. The sliding grooves on the clamping plates 4 and the clamping blocks 5 can move linearly along the sliding rails 3, and the sliding grooves on the gears can move linearly along the sliding rails 3. During the movement of the clamping blocks 5, the rods 72 are pulled outwards respectively, and the spring 73 is in a stretched state.

When the gear is moved to the right position, the rod 72 is released, and then the spring 73 is retracted, so that the rod 72 is pulled to move linearly along the cylinder 71 until the rod 72 is inserted into one of the positioning holes of the positioning hole group 6. This achieves the positioning of the clamping plate 4 and the clamping block 5 on the shaft body 1, and thus the gear is positioned on the shaft body 1. Because the positioning hole group 6 is composed of a plurality of positioning holes, when the rod body 72 is inserted into different positioning holes, the distance between the two clamping blocks 5 can be adjusted, and gears with different sizes can be clamped. The same gear may be held and positioned at different positions of the shaft body 1.

An oil injection pore passage is arranged in the clamping block 5 and is respectively communicated with the oil inlet and the oil outlet 8. The oil outlet 8 is located on the end face of the clamping block 5, the end face is attached to the gear, and the oil inlet is located on the side edge of the clamping block 5. The lubricating oil can flow out of the oil outlet 8 through the oil filling pore passage, and finally the gear is lubricated.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
