According to the utility model, the dial indicator is additionally arranged above the vernier caliper, so that the reading of the accurate dimension can be quickly realized, the measurement efficiency is improved, the wall thickness measurement of the spherical ring can be conveniently and quickly realized, and the measurement is accurate and stable.
Description
Technical Field
The utility model belongs to the technical field of calipers, and particularly relates to a vernier caliper.
Background
The vernier caliper as one kind of widely used high precision measuring tool consists of two parts, including one main scale and one sliding vernier attached to the main scale. If the scale value of the vernier is divided, the vernier caliper is divided into three types of 0.1 mm, 0.05 mm and 0.02 mm. The existing vernier caliper has the problem that the wall thickness of a spherical ring cavity (such as a sealing valve ring of a valve) cannot be accurately measured.
Disclosure of Invention
The technical problem to be solved by the utility model is as follows: a vernier caliper is provided to solve the problems in the prior art.
The technical scheme adopted by the utility model is as follows: the utility model provides a vernier caliper, includes ruler, fixed connection at the fixed cassette of ruler one end and the movable cassette of swing joint on the ruler, and fixed cassette and movable cassette lower part are provided with the jack catch that the symmetry is used for measuring hole and excircle, and fixed cassette top is provided with the positioning seat, and the amesdial is installed to activity cassette top, and the expansion probe of amesdial is just to the positioning seat.
Preferably, the probe tube of the dial indicator is spirally connected to the movable positioning seat through a fine thread and locked by a nut, and the movable positioning seat is arranged above the movable clamping seat.
Preferably, the probe tube of the dial indicator is locked by a locking screw after being inserted into the mounting hole at the upper end of the movable clamping seat.
Preferably, the positioning seat is provided with a boss facing the telescopic probe.
Preferably, the dial indicator is replaced by a dial indicator.
The utility model has the beneficial effects that: compared with the prior art, the utility model has the following effects:
(1) according to the utility model, the dial indicator is additionally arranged above the vernier caliper, so that the reading of the accurate size can be rapidly realized, the measurement efficiency is improved, the wall thickness measurement of the spherical ring can be conveniently and rapidly realized, and the measurement is accurate and stable;
(2) the fine thread connection is adopted, so that the telescopic adjustment of the probe tube is conveniently realized, and the accurate adjustment of the return zero of the dial indicator is realized;
(3) the bosses are arranged, so that the precision of the datum point/plane is improved, and the measurement precision is improved.
Drawings
FIG. 1 is a schematic view of a thread locking dial gauge type structure of the present invention;
fig. 2 is a schematic diagram of a screw locking dial indicator type structure of the utility model.
Detailed Description
The utility model is further described with reference to the accompanying drawings and specific embodiments.
Example 1: as shown in fig. 1, a vernier caliper comprises a ruler 1, a fixed clamping seat 2 fixedly connected to one end of the ruler 1 and a movable clamping seat 3 movably connected to the ruler 1, wherein clamping jaws 4 which are symmetrically used for measuring inner holes and outer circles are arranged on the lower portions of the fixed clamping seat 2 and the movable clamping seat 3, a positioning seat 5 is arranged above the fixed clamping seat 2, a dial indicator 6 is arranged above the movable clamping seat 3, and a telescopic probe 7 of the dial indicator 6 is opposite to the positioning seat 5.
Preferably, the probe tube 8 of the dial indicator 6 is spirally connected to the movable positioning seat 9 through a fine thread and locked by the nut 10, the movable positioning seat 9 is arranged above the movable clamping seat 3, the probe tube is conveniently adjusted in a telescopic mode through the fine thread, and the dial indicator is adjusted in a zero return mode accurately.
Preferably, the positioning seat 5 is provided with a boss 11 facing the telescopic probe 7, and the boss is arranged to improve the precision of the datum point/plane, thereby improving the measurement precision.
Preferably, the dial indicator 6 may be replaced with a dial indicator.
Example 2: as shown in fig. 2, the locking structure of the probe is different from that in embodiment 1, and the rest structures are the same, the probe of the dial indicator 6 is locked by a locking screw 12 after being inserted into a mounting hole 13 at the upper end of the movable clamping seat 3, a strip-shaped notch 14 is arranged below the mounting hole 13, and the locking screw 12 vertically penetrates through the strip-shaped notch 14 for locking, so that the locking is stable and reliable.
The use principle is as follows: and (3) zeroing the dial indicator or the dial indicator (realizing that the pointer can rotate left and right), and when the measured wall thickness is A, reading the dial indicator is B (positive rotation is positive value, and negative rotation is negative value), so that the measurement result is A + B.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention, and therefore, the scope of the present invention should be determined by the scope of the claims.
