Abstract

The utility model discloses a kind of clearance detector of ball screw, comprise base, clock gauge, clock gauge holder, screw rod holder, locking bed and dynamometer; Described clock gauge holder, screw rod holder, locking bed and dynamometer are fixed on base successively; Described clock gauge holder has the travel(l)ing rest be made up of connecting rod, and described clock gauge is arranged on travel(l)ing rest; Described screw rod holder upper end has U-shaped fixing port; Described locking bed upper end has rectangular opening, and rectangular opening is built-in with a fixture; Described dynamometer front end has feeler, and centre has dial plate, and rear end has push-and-pull rotating disk.The utility model structure is simple, with low cost, accurately can detect the play of ball screw, better detects the precision of ball screw, meets the accuracy requirement of Computerized flat knitting machine to needle-bar movement.

Description

The clearance detector of ball screw
Technical field
The utility model belongs to technical field of knitting machinery, particularly a kind of clearance detector of ball screw.
Background technology
Ball screw is parts conventional in Computerized flat knitting machine, is mainly arranged in shaking table, for the movement of needle-bar.The accuracy requirement of Computerized flat knitting machine to needle-bar movement is higher, so the play of ball screw there has also been higher requirement.General Requirements ball screw is under the acting force of axial about 800N, and what axis caused draws, compression elasticity variable is less than or equal to 0.005mm.Therefore, before ball screw is installed, need to detect the play of ball screw, to ensure the precision of needle-bar movement.
Summary of the invention
The purpose of this utility model is to provide a kind of structure simple, can detecting the play of ball screw fast, easily, ensure the clearance detector of the ball screw of needle-bar mobile accuracy.
For this reason, the technical solution of the utility model is: the clearance detector of ball screw, is characterized in that: it comprises base, clock gauge, clock gauge holder, screw rod holder, locking bed and dynamometer; Described clock gauge holder, screw rod holder, locking bed and dynamometer are fixed on base successively; Described clock gauge holder has the travel(l)ing rest be made up of connecting rod, and described clock gauge is arranged on travel(l)ing rest; Described screw rod holder upper end has U-shaped fixing port; Described locking bed upper end has rectangular opening, and rectangular opening is built-in with a fixture; Described dynamometer front end has feeler, and centre has dial plate, and rear end has push-and-pull rotating disk.
During utility model works, ball screw is fixed on screw rod holder, and with the fixture on locking bed, ball screw is clamped; Because fixture is placed in the rectangular opening of locking bed upper end, the rotation direction of fixture has been blocked, and can not be rotated, but can axial activity be carried out, so after clamp ball screw, ball screw can carry out axially-movable, but can not be rotated; Then regulate the travel(l)ing rest on clock gauge holder, make the detecting head of the clock gauge on travel(l)ing rest be against the end of ball screw, and be pressed into a certain amount of, make the pointer regulation of clock gauge to 0 value simultaneously; Then the feeler of dynamometer and the head of ball screw are fixed, rotate the push-and-pull rotating disk of dynamometer, just can carry out push-pull effort and test; When pulling force or thrust reach 800N, and when clock gauge data are less than 0.005mm, just can judge that this ball screw is as qualified.The utility model structure is simple, with low cost, accurately can detect the play of ball screw, better detects the precision of ball screw, meets the accuracy requirement of Computerized flat knitting machine to needle-bar movement.
Accompanying drawing explanation
Be described in further details below in conjunction with accompanying drawing and embodiment of the present utility model.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Embodiment
See accompanying drawing.The present embodiment comprises base 1, clock gauge 2, clock gauge holder 3, screw rod holder 4, locking bed 5 and dynamometer 6; Described clock gauge holder 3, screw rod holder 4, locking bed 5 and dynamometer 6 are fixed on base 1 successively; Described clock gauge holder 3 has the travel(l)ing rest 31 be made up of connecting rod, described clock gauge 2 is arranged on travel(l)ing rest 31; Described screw rod holder 4 upper end has U-shaped fixing port; Described locking bed 5 upper end has rectangular opening, and rectangular opening is built-in with a fixture 7; Described dynamometer 6 front end has feeler 61, and centre has dial plate 62, and rear end has push-and-pull rotating disk 63.
During the present embodiment work, ball screw 8 is fixed on screw rod holder 4, and with the fixture 7 on locking bed 5, ball screw is clamped; Because fixture 7 is placed in the rectangular opening of locking bed 5 upper end, the rotation direction of fixture 7 has been blocked, and can not be rotated, but can axial activity be carried out, so after fixture 7 clamps ball screw 8, ball screw 8 can carry out axially-movable, but can not be rotated; Then regulate the travel(l)ing rest 31 on clock gauge holder 3, make the detecting head of the clock gauge 2 on travel(l)ing rest 31 be against the end of ball screw 8, and be pressed into a certain amount of, make the pointer regulation of clock gauge 2 to 0 value simultaneously; Then the feeler 61 of dynamometer 6 is fixed with the head of ball screw 8, rotate the push-and-pull rotating disk 63 of dynamometer 6, just can carry out push-pull effort and test; When pulling force or thrust reach 800N, and when clock gauge 2 data are less than 0.005mm, just can judge that this ball screw 8 is as qualified.
