Description
Technical Field
The invention is applied to the technical field of measuring instruments, and particularly relates to a novel ball head micrometer and a measuring method thereof.
Background
In linear motion mechanism, the slip table is used for connecting and drives the connecting piece and obtains the removal effect as the moving member. The lower extreme both sides of slip table can be provided with the transverse groove, then install the billet on the transverse groove again, then be provided with the arc wall on the billet for the slip of slip table is spacing. For the distance measurement between the arc-shaped grooves, a common method is to use a micrometer to measure, but the conventional micrometer is difficult to obtain accurate test data for the arc-shaped grooves due to the structural limitation.
Chinese patent CN 204359233U discloses a micrometer with replaceable spherical measuring head, which adopts a structure in which a measuring rod and a measuring ball head are detachable, so that the ball head can be replaced, thereby measuring arc distances of different curvature radii; however, in this patent scheme, the change of bulb needs through tapping the screw hole on the bulb, then through screw hole and measuring stick terminal threaded connection, this has just produced a great deal of inconvenience: the bulb need tap out the screw hole, and the corresponding cost that has increased to the bulb size is less, the shape is slick and sly, snatchs inconveniently, and is very inconvenient when screwing up on the measuring stick, and it is comparatively troublesome to change. Therefore, a novel ball micrometer and a measuring method thereof, which have the advantages of simple structure, low cost and convenient ball replacement, are needed.
Disclosure of Invention
The invention aims to provide a novel bulb micrometer and a measuring method thereof, wherein the novel bulb micrometer is simple in structure, low in cost and convenient to replace a bulb.
The technical scheme adopted by the invention is as follows: the ruler comprises a ruler body and measuring rods arranged at two ends of the ruler body, wherein limiting sleeves are sleeved on the two measuring rods, through grooves are formed in the limiting sleeves, measuring ball heads are arranged in the through grooves, limiting rings are arranged at one ends, far away from the measuring rods, of the through grooves, and the measuring ball heads are matched with the limiting rings and the measuring rods.
Further, the stop collar is in threaded connection with the measuring rod.
Furthermore, ejector rods are arranged on the measuring rods and matched with the measuring ball heads.
The invention has the beneficial effects that: the measuring device comprises a ruler body and measuring rods arranged at two ends of the ruler body, wherein limiting sleeves are sleeved on the two measuring rods, through grooves are formed in the limiting sleeves, measuring ball heads are arranged in the through grooves, limiting rings are arranged at one ends, away from the measuring rods, of the through grooves, and the measuring ball heads are matched with the limiting rings and the measuring rods. Compared with the prior art, the invention has the following advantages: through adopting the stop collar, the structure that sets up logical groove in addition the spacing ring in the stop collar will measure the bulb restriction, then utilize the measuring stick to push up the measuring bulb on the spacing ring, make the measuring bulb expose, thereby can measure the arc-shaped groove, whole framework is simple, need not measure the bulb and process, and then reduce economic cost, and when needing to be changed, only need to place new measuring bulb on supporting stop collar, again by the stop collar cover can on the measuring stick, the operation is simple, it is convenient to change.

fig. 2 is an exploded view of the invention and the part to be measured.
Detailed Description
As shown in fig. 1 to 2, the embodiment of the present invention is: the ruler comprises a ruler body 1 and measuring rods 2 arranged at two ends of the ruler body 1, wherein limiting sleeves 3 are sleeved on the two measuring rods 2, through grooves 4 are formed in the limiting sleeves 3, measuring ball heads 5 are arranged in the through grooves 4, limiting rings 6 are arranged at one ends, far away from the measuring rods 2, of the through grooves 4, and the measuring ball heads 5 are matched with the limiting rings 6 and the measuring rods 2. The ruler body 1 is a conventional part, the limiting sleeve 3 is matched with the measuring rod 2, the through groove 4 is used for placing the measuring ball head 5, the limiting ring 6 is matched with the measuring rod 2, the position of the measuring ball head 5 can be limited, the measuring ball head 5 is prevented from falling off, and meanwhile, the measuring ball head 5 can be partially exposed to measure an arc-shaped groove to be measured. Therefore, the invention has simple integral structure, the measuring ball head 5 can be limited at a fixed position through the measuring rod 2, the limiting sleeve 3 and the limiting ring 6, so that the measuring ball head 5 does not need to be processed, the processing cost is favorably reduced, meanwhile, in the process of replacement and installation, only a new measuring ball head needs to be placed in the adaptive limiting sleeve, and then the limiting sleeve is sleeved on the measuring rod 2 to complete the replacement, the operation is simple, and the replacement is convenient.
In this embodiment, the stop sleeve 3 is screwed to the measuring rod 2. The matching mode of threaded connection is adopted, so that the connection between the limiting sleeve 3 and the measuring rod 2 is more stable, a better connection effect is obtained, the conditions of looseness and the like cannot occur easily, and the measuring accuracy is guaranteed.
In this embodiment, the measuring rod 2 is provided with a top rod 7, and the top rod 7 is matched with the measuring ball 5. The diameter of the ejector rod 7 is smaller than that of the measuring rod 2, and the ejector rod is used for tightly ejecting the measuring ball head 5, so that the ejector rod can be tightly attached to the limiting ring 6, can extend into the through groove with the smaller diameter, and is suitable for more limiting sleeves with different sizes.
The measuring method of the novel ball head micrometer comprises the following steps:
A. before measurement, the measuring ball head 5 and the limiting sleeve 3 which are matched with each other are prepared in advance, then one end, provided with the limiting ring 6, of the limiting sleeve 3 faces downwards, and the measuring ball head 5 is placed in the through groove 4;
B. sleeving the limiting sleeve 3 on the measuring rod 2 and screwing the limiting sleeve, wherein the ejector rod 7 props against the measuring ball head 5, so that the measuring ball head 5 is exposed;
C. during measurement, the two exposed measuring ball heads 5 are respectively aligned to the arc-shaped groove to be measured, and then the fine tuning screw of the micrometer is rotated to enable the two measuring ball heads 5 to be tightly attached to the arc-shaped groove to be measured, so that the measurement is completed;
D. when arc-shaped grooves with different sizes need to be measured, the limiting sleeve 3 and the measuring ball head 5 are taken down, and then the new limiting sleeve 3 and the measuring ball head 5 with proper sizes are replaced.
