Description
Technical Field
The utility model relates to a parts machining makes technical field, especially relates to an utilize slide caliper rule to carry out the auxiliary fixtures of usefulness to cylinder or circle profile structure in the part in the manufacturing process.
Background
In the part machining and manufacturing industry, there are many parts with cylindrical or circular contour structures, and therefore, during the manufacturing process, vernier calipers are often used to measure the dimensions of the cylindrical or circular contour structures in the parts. However, the caliper has a short caliper leg, and the size of the cylindrical or circular contour structure in the part is large, which exceeds the use specification of the caliper, so that the measured data has a large error.
SUMMERY OF THE UTILITY MODEL
For reducing the measuring error when slide caliper measures the great cylinder of part medium-size or circle profile structure, the utility model provides a slide caliper surveys circle and uses auxiliary fixtures, this slide caliper surveys circle and uses auxiliary fixtures include adapter sleeve, extension card foot and retaining member, the adapter sleeve is established on the card foot of slide caliper rule and pass through retaining member locking is fixed, extension card foot sets up the adapter sleeve outside is located between two card feet on the slide caliper rule. Like this, when using slide caliper rule survey circle, with slide caliper rule survey circle with auxiliary fixtures install fixed to the card foot of slide caliper rule, utilize extension card foot's length to the measurement specification of increase card foot effectively increases the use specification of slide caliper rule, and then can avoid leading to the great cylinder of size or the great measurement error of circle profile structure of slide caliper rule measurement part because of the card foot is short excessively, effectively improves the measurement accuracy of slide caliper rule to the great cylinder of size or circle profile structure. Additionally, the utility model discloses slide caliper rule is surveyed circle and is passed through the adapter sleeve and connect the card foot of extension card foot and slide caliper rule to fix the adapter sleeve locking on the card foot of slide caliper rule through the retaining member, connect convenient and stable.
Preferably, the connecting sleeve is a rectangular flat sleeve, and an inner wall connecting angle of the rectangular flat sleeve is an arc-shaped connecting angle surface. Like this, in equipment and use, can avoid the inner wall continuous angle department of adapter sleeve to cause the damage to the card foot of slide caliper rule because of there being the edges and corners, measurement accuracy when influencing slide caliper rule independent utility.
Preferably, the locking member is a locking bolt, and the locking bolt is installed in a locking screw hole located on a side wall of the connecting sleeve. Such retaining member simple structure, locking convenient and fast. Furthermore, the side wall of the connecting sleeve is provided with at least two locking screw holes, and the locking screw holes are located on the same side wall of the connecting sleeve. Like this, when the equipment, usable two at least locking bolts that are located on the same lateral wall of adapter sleeve fix adapter sleeve locking on the card foot of slide caliper rule, and locking fixed is stable good, can avoid influencing measurement accuracy because of adapter sleeve locking is fixed unstably, leads to the fact the damage even to the card foot of slide caliper rule.

FIG. 2 is an exploded view of the auxiliary tool for measuring circle of a caliper according to the present invention mounted on the caliper leg;
fig. 3 is an enlarged view of Q in fig. 2.
Detailed Description
The following describes the auxiliary tool for measuring circle by caliper in detail in conjunction with fig. 1, 2 and 3.
As shown in fig. 1, 2 and 3, the utility model discloses slide caliper rule is surveyed circle and is used auxiliary fixtures includes adapter sleeve 1, extension card foot 2 and retaining member 3, and wherein, 1 cover of adapter sleeve is established on slide caliper rule 4's card foot 41 and is locked fixedly through retaining member 3, and extension card foot 2 sets up in the adapter sleeve 1 outside and lies in between two card feet 41 on slide caliper rule 4. Preferably, the connecting sleeve 1 is a rectangular flat sleeve, and an inner wall connecting angle of the rectangular flat sleeve is provided with an arc-shaped connecting angle surface 11. Therefore, in the assembling and using processes, the damage to the clamping foot 41 of the caliper 4, especially the measuring surface of the clamping foot, caused by the edge angle at the connecting angle position of the inner wall of the connecting sleeve 1, and the influence on the measuring precision of the caliper 4 in the independent use can be avoided. Preferably, the connecting sleeve 1 and the extension clamping leg 2 can be connected by welding or by connecting bolts. Preferably, after the auxiliary tool for measuring the circle of the caliper is installed on the clamping foot 41 of the caliper 4, the extension clamping foot 2 and the clamping foot 41 are located on the same plane. Preferably, the locker 3 is a locking bolt, and the locking bolt is installed in a locking screw hole 121 formed at the sidewall 12 of the coupling sleeve 1. Such retaining member 3 simple structure, locking convenient and fast. Preferably, at least two locking screw holes 121 are provided on the side wall 12 of the connecting sleeve 1, and the locking screw holes 121 are located on the same side wall 12 of the connecting sleeve 1. Thus, when assembling, the connecting sleeve 1 can be locked and fixed on the clamping foot 41 of the caliper 4 by using at least two locking bolts positioned on the same side wall 12 of the connecting sleeve 1, the locking and fixing stability is good, and the influence on the measurement accuracy due to the unstable locking and fixing of the connecting sleeve 1 and even the damage to the clamping foot 41 of the caliper 4 can be avoided.
When using slide caliper rule survey circle, with slide caliper rule survey circle with auxiliary fixtures install fixed to the bayonet socket of slide caliper rule, utilize the length of extension bayonet socket to the measurement specification of increase bayonet socket effectively increases the use specification of slide caliper rule, and then can avoid leading to the great cylinder of size or the great measurement error of circle profile structure among the slide caliper rule measurement part because of the bayonet socket is short excessively, effectively improves the measurement accuracy of slide caliper rule to the great cylinder of size or circle profile structure. Additionally, the utility model discloses slide caliper rule is surveyed circle and is passed through the adapter sleeve and connect the card foot of extension card foot and slide caliper rule to fix the adapter sleeve locking on the card foot of slide caliper rule through the retaining member, connect convenient and stable.
