Description

Technical Field

[0001] This utility model relates to the field of oil casing coupling measurement technology, and in particular to a measuring tool for quickly measuring external threads and external taper. Background Technology

[0002] When producing API SPEC 5B oil casing external threads and special thread products, the taper of the semi-finished product cannot be measured. Generally, a taper template is used for comparison, which can only determine whether it fits or not, but cannot read the specific value. In addition, when measuring the thread taper, it is necessary to measure the change in diameter per unit length (1 inch), and it is difficult to ensure that the measurement is on the same axis. The measured value may be deviated, and the thread taper cannot be accurately measured. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned deficiencies in the existing technology by providing a measuring tool for quickly measuring external threads and external taper. It can quickly measure the external taper or thread taper, improving inspection efficiency and ensuring measurement accuracy. It is an effective measuring tool for improving production efficiency.

[0004] The present invention discloses a measuring tool for quickly measuring external threads and external taper. The technical solution is as follows: it includes a transverse sliding plate (1), a measuring tool spindle (2), and a measuring gauge (3). The measuring gauge (3) and the transverse sliding plate (1) are mounted on the measuring tool spindle (2). The measuring tool spindle (2) includes a measuring tool spindle body (2.1) and a fixed contact (2.2). The fixed contact (2.2) is located on the upper side of the measuring tool spindle body (2.1). The measuring gauge (3) is mounted on the upper end of the measuring tool spindle body (2.1). One end of the measuring gauge (3) is provided with a movable contact (3.1), and the movable contact (3.1) is positioned... On the upper side of the fixed contact (2.2); the transverse sliding plate (1) includes a transverse sliding plate body (1.1), a measuring contact surface (1.2), a slide groove (1.4) and a longitudinal connecting body (1.5). The transverse sliding plate body (1.1) and the longitudinal connecting body (1.5) are connected as one unit. A slide groove (1.4) is provided in the inner cavity of the longitudinal connecting body (1.5). The slide groove (1.4) is connected to the measuring tool spindle body (2.1) through the measuring groove (1.4). The upper side of the transverse sliding plate body (1.1) is the measuring contact surface (1.2), which contacts the end of the oil casing to be measured.

[0005] Preferably, the right end of the aforementioned transverse sliding plate body (1.1) is connected to the upper end of the longitudinal connecting body (1.5) as a whole, and the groove (1.4) in the longitudinal connecting body (1.5) is a cuboid structure.

[0006] Preferably, the cross-section of the measuring tool spindle body (2.1) is rectangular, and the length and width of the measuring tool spindle body (2.1) are smaller than the length and width of the slide (1.4).

[0007] Preferably, a transverse sliding plate locking screw (1.3) is installed on the side wall of the longitudinal connecting body (1.5) to fix the transverse sliding plate body (1.1) to a position on the measuring tool spindle body (2.1) by means of the transverse sliding plate locking screw (1.3).

[0008] Preferably, the distance between the movable contact (3.1) and the fixed contact (2.2) of the measuring instrument (3) is 1 inch, and they are on the same axis.

[0009] Preferably, the measuring gauge (3) is fixed to the main body (2.1) of the measuring instrument spindle by the measuring gauge locking screw (2.3).

[0010] The beneficial effects of this utility model are as follows: After calibration, this utility model can obtain the taper value of the product simply by placing it against the tapered surface or tapered thread of the oil casing to be measured. The original taper gauge can only measure the taper of the thread and requires measuring the change in diameter per unit length, which is slow. For tapered circles, taper gauges cannot be used for measurement and can only be compared with a taper template. This utility model solves the above problems, improves the efficiency of on-site inspection, can measure the taper of tapered circles, can improve the accuracy of semi-finished product processing, avoids defective products caused by "tool deflection" during processing, thereby ensuring the product dimensions during finishing and improving the product qualification rate.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example 1, refer to Appendix Figures 1-7 This utility model discloses a measuring tool for quickly measuring external threads and the taper of external cones. It includes a transverse sliding plate 1, a measuring tool spindle 2, and a measuring gauge 3. The measuring gauge 3 and the transverse sliding plate 1 are mounted on the measuring tool spindle 2. The measuring tool spindle 2 includes a measuring tool spindle body 2.1 and a fixed contact 2.2. The fixed contact 2.2 is located on the upper side of the measuring tool spindle body 2.1. The measuring gauge 3 is mounted on the upper end of the measuring tool spindle body 2.1, and a movable contact 3.1 is located at the fixed contact. 2.2 The upper side; the transverse sliding plate 1 includes a transverse sliding plate body 1.1, a measuring contact surface 1.2, a slide groove 1.4 and a longitudinal connecting body 1.5. The transverse sliding plate body 1.1 and the longitudinal connecting body 1.5 are connected as one unit. The slide groove 1.4 is provided in the inner cavity of the longitudinal connecting body 1.5. The slide groove 1.4 is used to connect with the measuring tool spindle body 2.1. The measuring contact surface 1.2 is located on the upper side of the transverse sliding plate body 1.1. The measuring contact surface 1.2 contacts the end of the oil sleeve 5 to be measured.

[0021] The right end of the aforementioned transverse sliding plate body 1.1 is connected to the upper end of the longitudinal connecting body 1.5 as a whole, and the sliding groove 1.4 inside the longitudinal connecting body 1.5 is a cuboid structure.

[0022] The cross-section of the aforementioned measuring tool spindle body 2.1 is rectangular, and the length and width dimensions of the measuring tool spindle body 2.1 are smaller than the length and width dimensions of the slide groove 1.4.

[0023] A transverse sliding plate locking screw 1.3 is installed on the side wall of the aforementioned longitudinal connecting body 1.5, and the transverse sliding plate body 1.1 is fixed to a position on the measuring tool spindle body 2.1 by the transverse sliding plate locking screw 1.3.

[0024] The distance between the movable contact 3.1 and the fixed contact 2.2 in the above-mentioned measuring table 3 is 1 inch, and they are on the same axis.

[0025] The aforementioned measuring gauge 3 is fixed to the main body 2.1 of the measuring tool spindle via the measuring gauge locking screw 2.3. It should be noted that the measuring gauge 3 is a conventional measuring gauge well known to those skilled in the art, and will not be described in detail here.

[0026] When using this utility model,

[0027] First, use the measuring tool mentioned in this utility model to zero the right-angle scale block 4;

[0028] Second, place this utility model outside the external thread 5.2 of the end of the oil casing 5 to be tested, and simultaneously place the measuring contact surface 1.2 against the end face of the oil casing 5.

[0029] Third, while ensuring that the base surface of the measuring instrument is in contact with the end face of the oil sleeve 5 with the external thread 5.2, push the transverse sliding plate 1 laterally so that the fixed contact 2.2 and the movable contact 3.1 are in contact with the outer cone circle at the same time. At this time, the value on the measuring instrument 3 is the taper of its product.

[0030] Fourth, if you want to measure the external taper 5.1 of the thread of the oil casing 5, first replace the movable contact 3.1 with the corresponding thread, repeat steps one and two, rotate the pipe, push the transverse sliding plate 1 laterally, and place the movable contact 3.1 in the position corresponding to the thread groove. At this time, the value on the measuring table 3 is the taper of its product.

[0031] After calibration, this utility model allows you to obtain the taper value of the product simply by placing it against the tapered surface or tapered thread of the oil casing to be measured. The original taper gauge could only measure the taper of the thread and required measuring the change in diameter per unit length, which was slow. It could not be used to measure the taper circle and could only be compared with a template, but after comparison, the specific taper value and the amount of adjustment required were unknown. This utility model solves the above problems, improves the efficiency of on-site inspection, can measure the taper of the tapered circle, can improve the accuracy of semi-finished product processing, avoid defective products caused by "tool deflection" during processing, thereby ensuring the product dimensions during finishing and improving the product qualification rate.

The fixed contact 2.2 is provided on the upper side of the measuring tool spindle body 2.1. The measuring gauge 3 is mounted on the upper end of the measuring tool spindle body 2.1. One end of the measuring gauge 3 is provided with a movable contact 3.1, and the movable contact 3.1 is located at the fixed contact 2.2. The upper side of the fixed contact 2.2; the transverse sliding plate 1 includes a transverse sliding plate body 1.1, a measuring contact surface 1.2, a slide groove 1.4 and a longitudinal connecting body 1.5. The transverse sliding plate body 1.1 and the longitudinal connecting body 1.5 are connected as one unit. The slide groove 1.4 is provided in the inner cavity of the longitudinal connecting body 1.5. The slide groove 1.4 is used to connect with the measuring tool spindle body 2.1. The measuring contact surface 1.2 is located on the upper side of the transverse sliding plate body 1.1. The measuring contact surface 1.2 contacts the end of the oil casing to be measured.

[0033] The difference from Example 1 is:

[0034] The measurement table 3 used in this embodiment is adjusted with the following parameters: its movement is twice the display value, that is, moving it 1mm results in a display value of 2mm, which facilitates display and observation.
