Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guide rail detection, in particular to a guide rail groove distance detection jig. Background Art
[0002] Guide rails are used in linear reciprocating motion situations. They have a higher rated load than linear bearings and can bear a certain torque. They can achieve high-precision linear motion under high load conditions. In the current guide rail and slider manufacturing industry, guide rail inspection jigs are used to inspect the guide rails before leaving the factory.
[0003] Due to the machining accuracy deviation of the guide rail grinding equipment and human operation reasons, there will be dimensional deviations between the guide rails ground in batches and in different groove positions of the same guide rail. The gap size after matching with the same slider is different, and this difference will cause the pre-load difference of the product.
[0004] However, most of the existing 6-meter-long linear rails use micrometer calipers to measure a few positions separately to confirm the groove spacing value of the guide rail, and cannot fully measure the entire long linear rail. This leads to the risk of being difficult to detect if problems occur in unmeasured positions. In addition, the micrometer caliper needs to be constantly taken in and out during the measurement process, which is inefficient. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] The utility model provides a technical solution:
[0025] See also Figures 1 to 3 , a guide rail groove distance detection fixture comprises a mahr table 5, a supporting side plate 11 is provided on one side of the mahr table 5, and a gauge fixing block 4 is provided on one side of the supporting side plate 11, a micro-moving slider 10 is slidably installed inside the gauge fixing block 4, and a follow-up steel column circulation module 7 is provided below the micro-moving slider 10, a fixed steel column circulation module 8 fixed below the gauge fixing block 4 is provided on one side of the follow-up steel column circulation module 7, a standard guide rail 3 is provided between the fixed steel column circulation module 8 and the follow-up steel column circulation module 7, and a guide rail 2 to be measured is placed at one end of the standard guide rail 3, and the vertical center lines of the guide rail 2 to be measured and the standard guide rail 3 coincide with each other, a marble table 1 is provided below the guide rail 2 to be measured, a spring guide shaft 9 is installed on one side of the follow-up steel column circulation module 7, and a support spring 12 is provided on the outer sleeve of the spring guide shaft 9.
[0026] A spacing adjustment rod 6 is provided on one side of the supporting side plate 11, and a protrusion is connected to the end of the spacing adjustment rod 6, one side of the protrusion is in contact with the follower steel column circulation module 7, the follower steel column circulation module 7 slides on the inspection fixture fixed block 4 through the micro-moving slider 10, and the follower steel column circulation module 7 is elastically connected to the supporting side plate 11 through the supporting spring 12, and the measuring contact head on the mahr meter 5 passes through the supporting side plate 11 and abuts against the follower steel column circulation module 7.
[0027] By adopting the above technical solution, the standard guide rail 3 and the guide rail 2 to be tested are first placed on the marble table 1, so that the standard guide rail 3 and the guide rail 2 to be tested are aligned with each other, and then the guide rail groove distance detection fixture is placed on the standard guide rail 3; the extrusion spacing adjustment rod 6 is rotated, and the spacing adjustment rod 6 drives the cam to rotate, thereby pushing the micro-moving slider 10 to slide, and then adjusting the spacing between the follow-up steel column circulation module 7 and the fixed steel column circulation module 8, thereby determining the standard value, and manually pushing the inspection fixture from the standard guide rail 3 to the guide rail 2 to be tested and continuing to push forward. At this time, the guide rail groove distance detection fixture will move on the guide rail 2 to be tested and display the size difference between the bead groove spacing on the guide rail 2 to be tested and the standard guide rail 3. The value can be read while moving. If the value changes, it means that there is a gap between the standard guide rail 3 and the guide rail 2 to be tested.
[0028] Specifically, Figure 4 As shown, a steel column groove 74 is provided on the follower steel column circulation module 7 and the fixed steel column circulation module 8, and a reciprocating steel column 71 is installed inside the steel column groove 74, a movable rod 72 is installed in the middle of the reciprocating steel column 71, and a guide groove 73 is provided at the connection between the movable rod 72 and the follower steel column circulation module 7 and the fixed steel column circulation module 8.
[0029] By adopting the above technical solution, when the guide rail groove distance detection fixture is placed on the standard guide rail 3, the entire inspection fixture relies on the force of the support spring 12 to make the reciprocating steel column 71 of the fixed steel column circulation module 8 and the follower steel column circulation module 7 fit tightly with the guide rail groove.
[0030] Working principle: adjust the pointer on the Mahr meter 5 to 0 o'clock. After the adjustment is completed, align the end face of the guide rail 2 to be tested with the standard guide rail 3, and push the inspection fixture from the standard guide rail 3 to the guide rail 2 to be tested by hand and continue to push forward. At this time, the guide groove distance detection fixture will move on the guide rail 2 to be tested and display the size difference between the bead groove spacing on the guide rail 2 to be tested and the standard guide rail 3. The value can be read while moving. After moving to the end of the guide rail 2 to be tested, remove the guide groove distance detection fixture and re-install it on the standard guide rail 3 and check whether the pointer of the Mahr meter 5 is still at "0". If there is a deviation, it can be reset to zero and the next guide rail can be tested;
[0031] When the guide rail groove distance detection fixture is placed on the standard guide rail 3, the entire inspection fixture relies on the force of the support spring 12 to make the reciprocating steel column 71 of the fixed steel column circulation module 8 and the follower steel column circulation module 7 fit closely with the guide rail groove. Since the contact between the mahr meter 5 and the follower steel column circulation module 7 has a certain interference, the pointer on the mahr meter 5 returns to the "0" position. At this time, the standard value is displayed on the mahr meter 5. Then the guide rail groove distance detection fixture is pushed flat onto the guide rail 2 to be tested. Since the fixed steel column circulation module 8 and the follower steel column circulation module 7 have a circulation channel steel column groove 74 of the reciprocating steel column 71, the reciprocating steel column 71 can reciprocate in the steel column groove 74, and the steel column and the guide rail are always fitted together under the force of the support spring 12.
[0032] Assuming that the groove spacing of the guide rail 2 to be tested is smaller than that of the standard guide rail 3, the follower steel column circulation module 7 will move to the right under the action of the spring, and the corresponding measuring contact head of the mahr meter 5 will also move to the right in the follower steel column circulation module 7, and the pointer on the mahr meter 5 will also deflect to the "-" negative value side. The difference between the guide rail 2 to be tested and the standard guide rail 3 can be directly read through the pointer. Assuming that the groove spacing of the guide rail 2 to be tested is larger than that of the standard guide rail 3, the pointer on the mahr meter 5 will deflect to the "+" positive value side, and the difference can also be read through the pointer.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
