It is installed on the floating measuring seat 3, and the fixed measuring PIN needle 6 and the floating measuring PIN needle 5 are axially perpendicular to the sliding direction of the floating measuring seat 3, and the elastic member 7 provides an upward elastic retaining force to the floating measuring seat 3. The slider 9 to be measured can be inserted in the space between the fixed measuring seat 4 and the floating measuring seat 3, and the floating measuring PIN needle 5 and the fixed measuring PIN needle 6 can be respectively inserted in the grooves on the upper and lower sides of the slider 9 to be measured, and the circumferential outer surface of the floating measuring PIN needle 5 is tightly against the bottom surface of the groove on the upper side of the slider 9 to be measured, and the circumferential outer surface of the fixed measuring PIN needle 6 is tightly against the bottom surface of the groove on the lower side of the slider 9 to be measured.
[0024] The elastic member 7 is used to provide elastic holding force to the floating measuring seat 3, so that the fixed measuring PIN needle 6 and the floating measuring PIN needle 5 are respectively tightly attached to the bottom surfaces of the grooves on both sides of the slider to be measured. Since the fixed measuring PIN needle 6 is immovable, the floating measuring PIN needle 5 measures the groove fit at both ends of the slider to be measured. The difference in distance between the floating measuring PIN needle 5 and the fixed measuring PIN needle 6 twice is the parameter of the consistency of the groove span of the slider to be measured. The smaller the distance difference, the better. This distance difference is reflected by the distance measuring device 2 measuring the height position of the floating measuring seat 3 twice.
[0025] The distance measuring device 2 is a height measuring meter, and the lower end of the height measuring meter is provided with a measuring contact 8 that can be elastically extended and retracted up and down, and the measuring contact 8 at the lower end of the height measuring meter can elastically press against the upper end surface of the floating measuring seat 3, and the height measuring meter can display the height measurement data. In addition to the height measuring meter, it can also be a laser rangefinder.
[0026] A plurality of first floating rollers 10 and a plurality of second floating rollers 11 are also provided. A first pressure block 12 and a second pressure block 13 are fixedly installed on the surface of the floating measuring seat 3 and the fixed measuring seat 4, respectively. Two first slots with openings facing each other are formed between the first pressure block 12 and the surface of the floating measuring seat 3, and two second slots with openings facing each other are formed between the second pressure block 13 and the surface of the fixed measuring seat 4. The axial ends of the plurality of first floating rollers 10 are respectively inserted into the two first slots, and the axial ends of the plurality of second floating rollers 11 are respectively inserted into the two second slots. The plurality of first floating rollers 10 form a row parallel to the surface of the floating measuring seat 3, and the plurality of second floating rollers 11 form a row parallel to the surface of the fixed measuring seat 4. The two ends of the plurality of first floating rollers 10 are clearance-matched with the two first slots, so that the plurality of first floating rollers 10 can roll in the two first slots, and the two ends of the plurality of second floating rollers 11 are clearance-matched with the two second slots, so that the plurality of second floating rollers 11 can roll in the two second slots.
[0027] When the slider to be measured is being measured, its end face contacts the outer circumferential side faces of the first floating roller 10 and the second floating roller 11 to form line contact, and there is a clearance fit between the first floating roller 10 and the second floating roller 11 and the first slot and the second slot. The first floating roller 10 and the second floating roller 11 themselves have a certain floating effect, so that the end face of the slider to be measured has a certain floating positioning effect, ensuring that the floating measurement PIN needle 5 and the fixed measurement PIN needle 6 are tightly fitted with the groove of the slider to be measured, ensuring the measurement accuracy, and avoiding the influence of the end face accuracy of the slider to be measured on the groove span detection error of the slider to be measured. Moreover, since the first floating roller 10 and the second floating roller 11 can roll, when the floating measurement seat 3 slides, the end face of the slider to be measured is in rolling contact with the second floating roller 11, and the friction is small, so as to avoid jamming and wear of the end face of the slider to be measured.
[0028] The first pressing block 12 and the second pressing block 13 are U-shaped structures with openings facing each other. Notch structures are respectively provided on the two side walls of the U-shaped structure. The notch structures are respectively spliced with the floating measuring seat 3 and the fixed measuring seat 4 to form a first slot and a second slot.
[0029] The elastic member 7 is a compression spring, and the elastically retractable two ends of the compression spring are respectively pressed against the opposite surfaces of the floating measuring seat 3 and the fixed measuring seat 4 .
[0030] The fixed measuring seat 4 is provided with a T-shaped guide column 14, and a compression spring is sleeved on the outer side of the end with a smaller diameter of the guide column. The floating measuring seat 3 is provided with a guide sleeve 15, and the guide sleeve 15 is slidably sleeved on the outer side of the end with a smaller diameter of the guide column, and the two ends of the compression spring in the elastic expansion and contraction direction are respectively tightly pressed against the step surface of the T-shaped structure of the guide column and the end surface of the guide sleeve 15 facing the fixed measuring seat 4.
[0031] The T-shaped guide column 14 is a pressure adjustment screw movably screwed to the fixed measuring seat 4. The T-shaped guide column 14 is a pressure adjustment screw, which is used to adjust the pressure of the compression spring by changing the position of the step surface of the T-shaped structure and thereby changing the compression amount of the compression spring.
[0032] The measuring tool base 1 is also provided with a linear guide rail 16 extending in the up-down direction, and the floating measuring seat 3 can be slidably mounted on the linear guide rail 16. The floating measuring seat 3 slides along the high-precision linear guide rail 16 to ensure that the floating measuring PIN needle 5 is accurately fitted with the groove on the slider to be measured, thereby ensuring the measurement accuracy.
[0033] The side walls of the fixed measuring seat 4 and the floating measuring seat 3 are both provided with handles 17. By pinching the handles 17, the floating measuring seat 3 can be pushed and pulled, which is convenient and labor-saving.
[0034] The measuring tool base 1 is also fixed with a limit stopper 18, which stops at the upper side of the floating measuring seat 3 to limit the sliding distance of the floating measuring seat 3. The limit stopper 18 limits the sliding distance of the floating measuring seat 3 to prevent the floating measuring seat 3 from sliding upward too far and damaging the contact of the height measuring gauge.
[0035] The detection principle of this utility model is as follows:
[0036] First, adjust the pressure adjustment screw to the appropriate pressure of the compression spring, then pinch the handle of the floating measuring seat 3 and apply pressure in the direction of the compression spring. At this time, the measuring floating seat slides linearly on the measuring tool base 1 along the high-precision linear guide 16. When enough space is left outside the floating measuring PIN needle 5 and the fixed measuring PIN needle 6, the end face A of the groove of the slider to be measured is placed against the outer circumferential surface of the first floating roller 10 and the second floating roller 11, and the groove on one side of the slider to be measured is placed on the fixed measuring PIN needle 6 on the fixed measuring seat 4. Then release the handle. At this time, the compression spring is released. , eject the floating measuring seat 3, the floating measuring PIN needle 5 on the floating measuring seat 3 is tightly fitted with the groove on the other side of the slider to be tested. At this time, the slider to be tested will be firmly fixed by the fixture, and at the same time, the floating measuring PIN needle 5 and the fixed measuring PIN needle 6 are respectively pushed against the maximum distance position of the grooves on both sides of the slider to be tested. At this time, the distance X between the fixed measuring PIN needle 6 and the floating measuring PIN needle 5 is displayed by the height measuring table, and the Mahr high-precision height measuring table is adjusted to zero. At this time, the end face of the slider to be tested that is clamped is the default reference end face, and the subsequent measured values are all based on the value of zeroing at this point;
[0037] When it is necessary to measure the second end face span of the slider to be measured, pinch the handle of the floating measuring seat 3 and apply pressure in the direction of the compression spring. At this time, the fixed measuring PIN needle 6 on the fixed measuring seat 4 is fixed, and the floating measuring seat 3 and the floating measuring PIN needle 5 thereon move in the opposite direction. When there is enough space outside the fixed measuring PIN needle 6 and the floating measuring PIN needle 5, take out the slider to be measured and turn it over. Replace it with the end face B at the other end of the slider to be measured and continue to stick to the outer circumferential surface of the first floating roller 10 and the second floating roller 11. Then release the handle. Since the fixed measuring PIN needle on the fixed measuring seat 4 6 is fixed, the pressure of the compression spring is released to push out the pressure, pushing the floating measuring seat 3 and the floating measuring PIN needle 5 thereon to move in the opposite direction. At this time, the slider to be tested is firmly fixed by the fixture. At this time, the difference between the distances Y and X between the fixed measuring PIN needle 6 and the floating measuring PIN needle 5 is displayed by the height measuring gauge. At this time, the value displayed on the Mahr high-precision height measuring gauge is the relative difference measured after the groove span at one end of the slider to be tested is measured by the height measuring gauge and returned to zero as a reference. If the value is infinitely close to 0, the consistency of the slider groove span is good. If the value ± fluctuates greatly, the consistency of the groove span is poor.
