Description

TECHNICAL FIELD

[0001] The utility model relates to a measurement auxiliary tool, especially a ball screw measurement auxiliary tool. BACKGROUND

[0002] Ball screw pair is a kind of transmission mechanical assembly that converts rotary motion of steel ball into linear motion, with characteristics of high positioning accuracy, long service life, low pollution and high-speed transmission and conversion transmission, etc., due to the above characteristics, ball screw pair has become one of important components on positioning and measurement system of recent precision technology industry and precision machinery industry.

[0003] In ball screw pair thread raceway processing, the relative position of thread raceway and reference surface of ball screw pair needs to be ensured, at this time, some detection means are needed to detect thread raceway related parameter size (raceway initial distance, contact angle, groove curvature, pitch, etc.) and size with relative angle and distance relationship with positioning reference, machining thread raceway process, grinding thread raceway and finished product state detection, generally, detection probe is added in numerical control machine tool to detect raceway actual position or three-coordinate measuring machine is sent to detect.

[0004] In this process, ball screw needs to be kept fixed to facilitate instrument detection, and this step needs more time in prior art, which also prolongs the time required for the whole detection process, is not conducive to improving production efficiency, therefore, a new scheme needs to be proposed to solve the above problems. SUMMARY

[0005] The utility model wants to solve the technical problem that the prior art detection means needs certain detection waiting time and longer waiting time, and provides a ball screw measurement auxiliary tool capable of quickly fixing screw shaft center and rotating direction.

[0006] The utility model adopts the technical scheme that a ball screw measurement auxiliary tool, including base, two detachable chocks are fixed on the base, two chocks form V-shaped fixed groove, detachable baffle is also fixed on the base, baffle is located at one end of fixed groove, positioning groove is arranged on baffle, when the ball screw to be measured is placed in fixed groove, bolt passes through positioning groove and is inserted into the limiting groove in the end of ball screw, the positioning of ball screw is realized by the mutual cooperation of chock and bolt.

[0007] Further, the positioning groove is cross-shaped, and the width of the positioning groove corresponds to the diameter of the bolt.

[0008] Further, the baffle is fixed to the base by bolts.

[0009] Compared with the prior art, the ball screw measurement auxiliary tool has the advantages that:

[0010] By placing the lead screw in the fixed groove, the axis of the lead screw can be positioned, and then the baffle fixes the lead screw through the latch, so that the axis center and the rotation direction of the lead screw are fixed, thereby saving a lot of time required for positioning, thereby shortening the waiting time required for detection, improving the working efficiency, and also applicable to various detection instruments such as profile instrument, three-coordinate, on-site rapid instrument, etc., so that the tool has a wider application range.

[0014] The utility model will be further described in detail in combination with the drawings.

[0015] As shown in Figure 1 and Figure 2 , a ball screw measurement auxiliary tool, comprising a base 1, two detachable stop blocks 2 are fixedly arranged on the base 1, the two stop blocks 2 form a V-shaped fixed groove, the fixed groove is used for placing a ball screw 5, thereby playing a positioning role on the axis of the ball screw 5, ensuring that the lead screw does not roll during detection, and because of the V-shaped shape, the position of the ball screw 5 of the same specification is relatively fixed on the fixed groove, which is more convenient for positioning the axis of the ball screw 5, can be more conveniently aligned, and the V-shaped arrangement also makes the ball screws 5 of different specifications be clamped at different positions, which not only can be used to improve the flexibility of detection, but also avoids the confusion of different ball screws 5 during detection, and the base 1 is also fixed with a detachable baffle 3, the baffle 3 is located at one end of the fixed groove, and the baffle 3 is provided with a positioning groove 31, when the ball screw 5 to be measured is placed in the fixed groove, the latch 32 is inserted into the limiting groove 51 at the end of the ball screw 5 through the positioning groove 31, the positioning of the ball screw 5 is realized through the cooperation of the stop block 2 and the latch 32, so that the ball screw 5 is fixed on the tool, thereby facilitating the subsequent detection process.

[0016] The positioning groove 31 is cross-shaped, the width of the positioning groove 31 corresponds to the diameter of the plug pin 32, the cross-shaped positioning groove 31 can correspond to the position of the limiting groove 51 on the ball screw 5, the plug pin 32 can be inserted into different positions according to the different positions of the limiting groove 51 on the ball screw 5, so that the ball screw 5 cannot move during detection, and the accuracy of the detection result of the ball screw 5 is ensured.

[0017] When the ball screw to be detected is placed in the fixed groove, the plug pin is inserted into the limiting groove at the end of the ball screw through the positioning groove, and the positioning of the ball screw is realized through the cooperation of the stop block and the plug pin.

[0018] The whole detection process only needs to put the ball screw 5 into the fixed groove, then install the baffle 3 on the base 1, and fix the ball screw 5 through the plug pin 32, so that the instrument can be used to detect the ball screw 5, and most of the operations required in the positioning step in the detection process in the prior art are saved, so that the detection time can be saved, the efficiency can be improved to a certain extent, and the tool can also be adapted to various detection instruments and can play a role in different detection modes, so that it has a wider application range.

[0019] The protection scope of the utility model includes but is not limited to the above embodiment, the protection scope of the utility model is subject to the claims, any replacement, deformation, improvement of the technical personnel in the art to the present technology easily thought of falls into the protection scope of the utility model.
