Description
Technical Field
The utility model relates to the technical field of ball screws, in particular to an end plug type reverser for a ball screw pair.
Background
The ball screw pair is an ideal device for interconversion between rotary motion and linear motion, and the working principle is as follows: the screw rod and the nut are provided with the arc-shaped spiral grooves, the spiral grooves are filled with the steel balls, the steel balls roll back and forth in front of the screw rod and the nut through the reverser, sliding friction is converted into rolling friction, the efficiency and the precision are higher, and the screw rod and the nut are mostly applied to precise machine equipment.
The end plug type reverser is a device which is used in a screw rod and nut mechanism and enables a ball chain to circularly roll in a bent raceway, and solves the problems of friction, collision and motion continuity between balls. The ball rolling path structure comprises a base body and a ball rolling path, wherein a molded line in the ball rolling path is formed by two tangent circular arcs, the circular arcs are divided into a first circular arc and a second circular arc, the first circular arc is tangent to a central straight line at an inlet of the ball rolling path, the second circular arc is tangent to an oblique line at an outlet of the ball rolling path, and an included angle between the oblique line and a horizontal line at the outlet of the ball rolling path is a helix angle.
The common reverser forms include floating, end cap, cover plate, spigot and slip. The end plugs are fewer in domestic use, have the advantages of convenience in installation and compact structure, can be installed under the condition that two ends of the thread are optical axes, and have lower requirements on the screw rod compared with other reversers such as floating reversers.
The common connection mode is screw connection, the screw connection is in a large adjustable range, and the problem of positioning accuracy of the reverser needs to be solved because steel balls need to be adjusted continuously to roll in the reverser smoothly and unimpededly.
Disclosure of Invention
The utility model aims to provide an end plug type reverser for a ball screw pair, which aims to solve the problem of positioning precision of the reverser. In order to realize the purpose, the utility model adopts the following technical scheme: the utility model provides a vice end stopper formula reverser of using of ball screw, includes the reverser body, wherein is equipped with circular boss on a side end face of reverser body, is equipped with formula screw hole that sinks on the opposite side end face, is provided with ball raceway and slant muscle on the inboard circular arc section of reverser body, and the ball raceway intercommunication on ball raceway and the nut body, slant muscle tangential direction is the same with the lead screw helix direction.
Furthermore, a circular concave table is arranged on the nut body, and a circular boss on the end plug type reverser is embedded with the circular concave table on the nut body.
Further, the oblique ribs 23 are engaged with the threaded raceways of the lead screw when assembled.
Furthermore, the number of the sunken threaded holes is two.
Compared with the prior art, the utility model has the advantages that: the machine can be used for making objects with higher precision in a shorter time, so that the machining efficiency and the quality are greatly improved.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
As shown in fig. 1 to 3, the end plug type reverser 2 for a ball screw pair of the present invention has an arc-shaped structure, and includes a reverser body 21, wherein a circular boss 22 is provided on one end surface of the reverser body 21, and a sunken screw hole 25 is provided on the other end surface, and the sunken screw hole 25 penetrates through both end surfaces of the reverser body 21. During assembly, the end plug type reverser 2 is embedded into circular arc grooves on two sides of the nut body 3, circular concave platforms are arranged on the bottom surfaces of the circular arc grooves, and the circular bosses 22 on the end plug type reverser 2 are embedded with the circular concave platforms on the nut body 3 for positioning.
Be provided with ball raceway 24 and slant muscle 23 on the inboard circular arc section of reverser body 21, ball raceway 24 and the ball raceway intercommunication on the nut body 3, and slant muscle 23 tangential direction is the same with the screw 4 helix direction, and slant muscle 23 just in time blocks the screw thread raceway at screw 4 when the assembly, fixes a position.
Further, the reverser body 21 is provided with two sunken screw holes 25 which fix the reverser body 21 to the nut body 3 by the locking screws 1, which has a better positioning effect with respect to single screw fixation.
The nut dress after the assembly is on lead screw 4, and the steel ball makes a round trip to roll between its inside raceway and end plug formula reverser 2, rotates and turns into rectilinear motion, has solved the installation positioning accuracy problem of end plug formula reverser, makes it can go to the thing that the precision is higher with shorter time, makes its machining efficiency and quality have great promotion.
The foregoing is merely a preferred embodiment of the utility model and is not intended to limit the utility model in any manner. Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto.
