Abstract
The utility model discloses a nut steel ball circulator which is mainly used on a ball guide screw and is formed by an assembly made of two high-stability plastic steels (POM), and the assembly is provided with a rail groove, an inserting handle, an inserting hole and a joint surface; the mutually matched components can be respectively and alternately inserted and combined according to the insertion handle and the insertion hole which are arranged on the joint surface to form a component with a steel ball track, and the component is arranged on the groove of the nut of the ball guide screw to form a stable and smooth nut steel ball circulator capable of reflowing the steel balls.
Description
Technical Field
The utility model belongs to the technical field of the nut steel ball and specifically relates to a nut steel ball circulator.
Background
There are a variety of ball screw sets available on the market, for example; the ball is the steel ball extrinsic cycle or like the utility model discloses the steel ball belongs to the internal circulation formula, and this kind of ball screw group is equipped with the circulator that provides the steel ball circulation roll usually at its nut position, because this circulation track is closed pipeline form, these circulation tracks can't be made with the traditional method of machine cutting processing, therefore the circulator adopts the precision dewaxing casting method to form closed track, and the manufacturing cost of adopting this method is too high, is not conform to bulk production.
The present invention is an improved utility model (patent No. ZL201721485664.7) applied by the applicant at 2017.11.9 to the national intellectual property office, which has the disadvantages that the L-shaped rail grooves formed at the lower edges of the two components of the ball circulator not only increase the material cost, but also the L-shape causes the following disadvantages:
(1) the two components are increased in matching area, so that the two components cannot be closely assembled to form a good circulator.
(2) The L-shaped rail groove easily causes the problem that the steel balls in the rail groove roll more smoothly.
(3) The steel ball track of the L-shaped track groove is easy to cause steel ball blockage, so that the circulator breaks down.
All the above disadvantages are to be improved, and the application is filed.
SUMMERY OF THE UTILITY MODEL
A primary object of the present invention is to provide a nut steel ball circulator, which can smoothly and stably flow back a ball screw of a steel ball.
Based on this, the utility model mainly adopts the following technical means to realize the above-mentioned purpose.
A kind of nut steel ball circulator, include two and make by high stable plastic steel, the appearance presents two assemblies of the block, these two assemblies have faying surfaces, the lower edge department of two assemblies has arcuate shapes and rail groove to pass the assembly longitudinally; the joint surfaces of the two components are provided with inserting handles and inserting holes so that the two components can be mutually inserted and combined, and the rail grooves of the two components are involutory to form a steel ball track which can enable the steel balls to roll in.
Furthermore, the insertion handles and the insertion holes arranged on the two components can be mutually inserted and combined along the arranged joint surfaces to form close fit.
After the technical means is adopted, the utility model discloses set up on the nut slot of ball driving screw and become the nut steel ball circulator that can steadily, smoothly flow back the steel ball in ball driving screw with the help of the subassembly that mutually supports, this nut steel ball circulator can provide the function the same with closed track, and its steel ball through this steel ball circulator can make ball guide screw group can smoothly work along the orbital guided motion of circulation really.

Detailed Description
Referring to fig. 1 to 5, the present invention relates to a nut ball circulator 2, the nut ball circulator 2 is mainly made of two high-stability plastic steels (POM) and has two block- shaped components 4 and 6, the two components 4 and 6 are provided with joint surfaces 46 and 66, the lower edges of the two components 4 and 6 are both provided with arc- shaped grooves 44 and 64 longitudinally penetrating the two components 4 and 6, and the joint surfaces 46 and 66 of the two components 4 and 6 are provided with insertion handles 42 and 62 and insertion holes 48 and 68, and the joint surfaces 46 and 66 of the two components 4 and 6; please refer to fig. 4 and 5; the function of the insertion handles 42, 62 and the insertion holes 48, 68 on the two components 4, 6 is to make the two components 4, 6 which can be mutually matched can be alternately inserted and combined into a tight fit along the insertion handles 42, 62 arranged on the joint surfaces 46, 66 arranged on the two components 4, 6 and the insertion holes 48, 68, so that the rail grooves 44, 64 on the two components 4, 6 which are in block shape are closed to form the nut steel ball circulator 2 of the steel ball track 8 which makes the steel balls roll in the inner part, and the nut steel ball circulator 2 used for the ball guide screw rod can be arranged on the groove preset on the nut on the ball guide screw rod in sequence two by two to make the utility model discloses a nut steel ball circulator 2 which can stably and smoothly flow back the steel balls, and the ball guide screw rod group can be smoothly operated by the continuous circulation of the steel ball circulator 2 on the ball guide screw rod through the steel balls.
Claims (2)
1. A kind of nut steel ball circulator, characterized by that, include two high stable plastic steel make, the appearance presents two assemblies of the block, these two assemblies have faying surfaces, two lower edges of assembly have arcuate shape and rail groove to run through assembly longitudinally; the joint surfaces of the two components are provided with inserting handles and inserting holes so that the two components can be mutually inserted and combined, and the rail grooves of the two components are involutory to form a steel ball track which can enable the steel balls to roll in.
