Description
Technical field
The utility model relates to ball screw detection technique field, specially a kind of screw rod vibration detection screw workpiece clamp
Set.
Background technique
Ball screw has as accurate transmission parts, the accuracy of machining accuracy and precision instrument to industrial equipment
Important influence, therefore when whether breaking down before being put into use or in use process, it requires to detect it
To ensure the accuracy of ball screw, existing ball screw detection lacks automatic detection device, usually uses dial gauge, thousand points
Table manual measurement, not only time-consuming effort, accuracy is relatively low, therefore applicant has designed and developed a kind of automatic detection and ball wire
The device of the closely related screw rod vibration of bar precision particularly needs one kind to grip ball screw in automatic detection device
The component of workpiece is to guarantee the accuracy measured.
Utility model content
The low disadvantage of effort, accuracy, the utility model provide one kind when check fee manual for existing ball screw
Screw rod vibration detection screw workpiece collet, structure is simple, can be used in screw rod vibration automatic detection device gripping rolling
The screw of ballscrew workpiece to facilitate the automatic detection of ball screw, and guarantees the accuracy of detection.
The utility model adopts the following technical solution: it is characterized by: it includes telescopic screw workpiece collet, the work
Part collet center is that two sections communicated clamp through-hole, each described to clamp through-hole and be connected with respectively at the both ends of the workpiece collet
Split ring has opposite lockhole in two ends of the opening of the split ring, the split ring.
It is further characterized by:
Clamp that through-hole is coaxial described in two sections and diameter small one and large one；
The split ring opening direction at both ends is opposite；
Two opposite lockholes are coaxial and diameter small one and large one；
The lateral wall nickel plating of the workpiece collet.
After adopting the above structure, telescopic workpiece collet both ends are equipped with split ring, the both ends of split ring to the utility model
It is provided with opposite lockhole, one section by the nut sleeve of ball screw workpiece mounted in workpiece collet clamps in through-hole, passes through split ring
The lockhole at both ends can clamp the screw of ball screw workpiece, thus fixed ball screw workpiece to be detected, and then facilitate rolling
The automatic detection of ballscrew, and guarantee the accuracy of detection.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the longitudinal section view of the utility model.
Fig. 3 is the partial sectional view of the utility model one end.
Fig. 4 is the partial sectional view of the utility model other end.
Specific embodiment
1 ~ 4 pair of the utility model is further described with reference to the accompanying drawing:
As illustrated in fig. 1 and 2, the utility model provides a kind of screw rod vibration detection screw workpiece collet comprising sleeve
Formula screw workpiece collet 1,1 center of workpiece collet are that two sections communicated clamp through-hole 6(7), two sections clamp through-hole 6(7) it is coaxial and
Diameter small one and large one, as shown in Fig. 2, the diameter for clamping through-hole 6, which is greater than, clamps the diameter of through-hole 7, screw workpiece collet is clamped
Different length, different pore size can be arranged in through-hole according to the actual situation, to be suitable for different types of ball screw workpiece；Workpiece clamp
Set both ends clamp through-hole, and one end connects the screw of ball screw workpiece, and the other end connects rotary shaft, can both make rotating device
Drive screw rotation to measure a vibration of bar, also having between certifiable ball screw workpiece and rotary shaft can screw mandrel movement
Stroke space；At the both ends of workpiece collet 1, through-hole 6(7 is each clamped) it is connected with split ring 2(5 respectively), in split ring 2(5)
Opening, two ends of split ring 2 have opposite lockhole 3 and lockhole 4, two ends of split ring 5 are opened respectively
There are opposite lockhole 3 ' and lockhole 4 ', the split ring 2 at both ends and the opening direction of split ring 5 are on the contrary, can be improved the effect of locking
And guarantee that whole device balances when workpiece rotation and measurement, two opposite lockholes are coaxial and diameter small one and large one, i.e. lockhole 3
Greater than lockhole 4, lockhole 3 ', coaxial and lockhole 3 ' diameter is greater than lockhole to coaxial and lockhole 3 diameter with lockhole 4 ' with lockhole 4
4 ', it is preferable that lockhole 3 and lockhole 3 ' are stepped hole, in one end that two opposite lockholes are connected, lockhole 3(3 ') with lockhole 4
The aperture of (4 ') is equal, as shown in Figures 3 and 4, to further increase locking effect；The lateral wall nickel plating of workpiece collet 1, surface
Nickel plating both protects workpiece collet not corroded as protecting decorative coating, durable, and has aesthetic effect.
Its working principle is that: the nut sleeve of ball screw workpiece clamps in through-hole 7 mounted in 1 minor diameter of workpiece collet, leads to
Cross lockhole 3(4 opposite at open-ended ring 2) it is fixed with hex bolts nut, 1 major diameter of workpiece collet clamps the company of through-hole 6
It connects the main shaft of rotating device and is fixed by lockhole 3 ' (4 ') opposite at open-ended ring 5 with hex bolts nut, analog
The other end of ball screw workpiece is placed in detection platform, is held out against by jacking apparatus by the transmission of ball screw, makes to rotate
Axis, ball screw workpiece and the detection platform for connecting jacking apparatus start rotating device and drive workpiece on same axial line
Collet rotates and then drives the screw rotation of ball screw, can be detected and ball screw essence by the detector in detection platform
Closely related screw rod vibration is spent, to facilitate the automatic detection of ball screw, and guarantees the accuracy of detection, makes ball screw
Detection it is time saving and energy saving, and effectively improve accuracy.
