Drawings
Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.
Fig. 2 shows a schematic side view of a nut according to an embodiment of the present invention.
Fig. 3 shows a schematic view of a cage structure according to an embodiment of the present invention.
In the figure: 1. the novel guide rod structure comprises a lead screw, 2 parts of a guide rod, 3 parts of a nut, 4 parts of a lining, 5 parts of a retainer, 6 parts of a ball, 7 parts of a connecting part, 8 parts of a mounting block and 9 parts of a sealing baffle.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model relates to a vice guide rail of cylinder, including lead screw 1, guide arm 2, nut 3, bush 4, lead screw and nut pass through threaded connection, and lead screw and guide arm are parallel, and the guide arm passes the nut, and the bush is installed outside the nut, is equipped with holder 5 between bush and the nut, is equipped with a plurality of balls 6 on the holder, and the ball contacts nut and bush respectively, and the bush is equipped with connecting portion 7. The bush and the nut are connected through the ball, so that abrasion can be reduced. The connection portion may be threaded or the like to connect the outer structure for movement with the bushing.
The working principle of the above embodiment is that the screw rod, the guide rod and the nut can realize linear motion, the guide rod limits the rotation of the nut, the external driving force drives the screw rod to rotate, the nut can be driven to do linear motion, and the bushing and the nut can rotate without limitation, so that the embodiment can realize the cylindrical auxiliary guide rail.
According to the above embodiment, preferably, the device further comprises a mounting block 8, two ends of the guide rod are respectively and fixedly connected with the mounting block, and two ends of the lead screw are connected with the mounting block through bearings. The mounting block is used for mounting the guide rail.
According to the above embodiment, the nut and the bush are preferably provided with the seal retainer 9, the thrust ring, and the snap ring at both ends. Lubricating grease can be added between the nut and the bush, and the sealing baffle can prevent the grease from leaking. The thrust ring is used to prevent the cage from moving axially. The stop ring is used for preventing the retainer from moving.
According to the above embodiment, the sealing baffle is preferably provided with a sealing gasket or sealing felt.
According to the above embodiment, preferably, the holder is provided with a plurality of through holes, the through holes are arranged in a staggered manner, and steel balls are installed in the through holes. The embodiment discloses a retainer structure which is convenient to implement.
According to the above embodiment, preferably, the through holes are spirally distributed on the surface of the holder. The structure of this embodiment makes the range of ball more even, makes the atress of each ball more balanced, reduces the excessive wearing and tearing of ball.
The utility model has the advantages that: a cylindrical auxiliary guide rail is realized.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
