Description

Technical Field

[0001] The utility model belongs to the technical field of double-ended spline sleeves, in particular to a double-ended spline sleeve. Background Art

[0002] A spline sleeve is a mechanical part that usually has spline teeth on its inner hole and outer surface. It is used in conjunction with a spline shaft, and the tooth profile of the spline shaft matches the tooth profile of the inner diameter of the spline sleeve to form a mutually meshing structure.

[0003] When using a common spline sleeve, a large force is required to insert the nozzle rod into the spline sleeve, which is laborious and inconvenient for personnel to operate. In addition, the nozzle rod is prone to rotational deviation during movement. In view of this, we propose a double-head spline sleeve. Utility Model Content

[0004] The utility model aims to provide a double-ended spline sleeve to solve the problems raised in the above-mentioned background technology.

[0005] In view of this, the utility model provides a double-ended spline sleeve, comprising:

[0007] Two movable grooves, the two movable grooves are symmetrically opened on the inner wall of the circular sleeve, a plurality of steel balls are movably installed in the movable grooves, the inner wall of the circular ring 1 and the bottom of the two movable grooves are fixedly installed with protrusions 2, and the inner wall of the circular ring 2 and the top of the two movable grooves are fixedly installed with protrusions 1;

[0008] A limiting groove is provided on the circumferential side of the circular sleeve, a threaded hole is provided on the circumferential side of the spline sleeve body and on one side of the limiting groove, a second screw is threadedly installed in the threaded hole, one end of the second screw extends into the limiting groove, a plurality of tooth blocks are fixedly installed on the circumferential side of the spline sleeve body, and a round tube is fixedly installed on the bottom of the spline sleeve body.

[0009] In the technical scheme, through the provision of circular ring 2, the suction nozzle rod can be first inserted into circular ring 2 from top to bottom. At this time, the two protrusions 1 in the circular ring 2 will respectively enter the two grooves on the inverted suction nozzle rod. At this time, the two protrusions 1 can limit the suction nozzle rod to ensure that the suction nozzle rod will not rotate when it moves downward. Then the bottom end of the suction nozzle rod will enter the circular sleeve. At this time, several steel balls in the two movable grooves will respectively enter the two grooves on the inverted suction nozzle rod. Then the suction nozzle rod continues to move downward. Under the action of friction, the downward movement of the suction nozzle rod will drive several steel balls to rotate, and then the bottom end of the suction nozzle rod will enter circular ring 1. At this time, the two protrusions 2 in the circular ring 1 will respectively enter the two grooves on the inverted suction nozzle rod, and then the suction nozzle rod will pass through the bottom end of the circular tube. Under the action of the rotation of several steel balls, the suction nozzle rod can move downward more smoothly without jamming.

[0010] When the spline sleeve body is in use, the spline sleeve body can realize power transmission through a plurality of tooth blocks, and then the rotation of the spline sleeve body will drive the rotation of the ring one, the round sleeve and the ring two, and the rotation of the ring one, the round sleeve and the ring two will respectively drive the nozzle rod to rotate through two protrusions two, a plurality of steel balls and two protrusions one, to ensure that the rotation of the spline sleeve body can drive the nozzle rod to rotate.

[0011] In the above technical solution, further, the bottom end of the screw 1 is threadedly connected to the round sleeve.

[0012] In this technical solution, it is ensured that screw one can fix ring two on the round sleeve.

[0013] In the above technical solution, further, the inner diameters of the circular ring 1, the circular sleeve, the circular ring 2 and the circular tube are equal.

[0014] In this technical solution, the structural stability of the circular ring 1, the circular sleeve, the circular ring 2 and the circular tube is ensured.

[0015] In the above technical solution, further, the diameter of the steel ball is greater than the width of the opening of the movable groove.

[0016] In this technical solution, it is ensured that the steel ball will not fall off from the movable groove.

[0017] In the above technical solution, further, the plurality of steel balls are distributed vertically with equal spacing.

[0018] In this technical solution, it is ensured that the force on a plurality of steel balls is uniform.

[0019] In the above technical solution, further, one end of the second screw is plugged into and matched with the limiting groove.

[0020] In this technical solution, it is ensured that one end of the second screw can be inserted into the limiting groove.

[0021] In the above technical solution, further, the spline sleeve body and the round tube are an integrally formed structure.

[0022] In this technical solution, the structural stability of the spline sleeve body and the round tube is ensured.

[0023] The beneficial effects of the utility model are:

[0024] 1. The double-headed spline sleeve can first insert the suction nozzle rod into the circular ring 2 from top to bottom through the provided circular ring 2. At this time, the two protrusions 1 in the circular ring 2 will respectively enter the two grooves on the inverted suction nozzle rod. At this time, the two protrusions 1 can limit the suction nozzle rod to ensure that the suction nozzle rod will not rotate when moving downward. Then the bottom end of the suction nozzle rod will enter the circular sleeve. At this time, several steel balls in the two movable grooves will respectively enter the two grooves on the inverted suction nozzle rod. Then the suction nozzle rod continues to move downward. Under the action of friction, the downward movement of the suction nozzle rod will drive several steel balls to rotate, and then the bottom end of the suction nozzle rod will enter the circular ring 1. At this time, the two protrusions 2 in the circular ring 1 will respectively enter the two grooves on the inverted suction nozzle rod, and then the suction nozzle rod will pass through the bottom end of the round tube. Under the action of the rotation of several steel balls, the suction nozzle rod can move downward more smoothly without jamming.

[0025] 2. For the double-headed spline sleeve, when the spline sleeve body is in use, the spline sleeve body can realize power transmission through a plurality of tooth blocks, and then the rotation of the spline sleeve body will drive the ring one, the round sleeve and the ring two to rotate, and the rotation of the ring one, the round sleeve and the ring two will respectively drive the nozzle rod to rotate through two protrusions two, a plurality of steel balls and two protrusions one, to ensure that the rotation of the spline sleeve body can drive the nozzle rod to rotate.
