[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for drilling holes in the body of a flow meter. Background Technology

[0002] A flow meter, also known as a flow meter, measures the instantaneous flow rate and cumulative volume of a liquid, and can also be used for quantitative control of liquids. It features high accuracy, long lifespan, and simple operation and maintenance. It is mainly used in industrial production processes, energy metering, environmental protection engineering, transportation, biotechnology, scientific experiments, marine meteorology, and the monitoring of rivers and lakes.

[0003] Flow meters typically have probes installed to measure flow rate. Therefore, holes need to be drilled in the meter body to provide a mounting position for the probes. During the drilling process, the meter body needs to be clamped and fixed. However, the meter body is mostly a cylindrical structure, and the clamping and fixing device is usually a flat-nose pliers. Therefore, it is not easy to position it during the fixing process, and it is also easy to shake during the drilling process, resulting in low drilling accuracy. The alignment and tool setting during the processing process are time-consuming and the work efficiency is low. Summary of the Invention

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] As shown in Figures 1, 2, and 4, a positioning device for drilling holes in a flow meter body includes a base 1 and a clamping assembly mounted on the base 1. The base 1 has a flat plate structure with a flat upper surface. The clamping assembly includes a support seat 2, which is detachably fixed to the base 1. A support plate 3 is detachably mounted on the support seat 2. The support plate 3 is an arc-shaped plate that adapts to the shape of the inner wall of the flow meter body. A pressing assembly is provided on the base 1 for pressing and fixing the flow meter body. The pressing assembly includes a pressing plate 4 and a support rod 5, which are perpendicularly arranged. One end of the support rod 5 abuts against the base 1. A locking rod 6 is provided between the pressing plate 4 and the base 1, and a first locking nut 7 is threaded onto the locking rod 6. The first locking nut 7 is located above the pressure plate 4. In this utility model, when drilling the flow meter body, the support plate 3 can be inserted into the flow meter body and then placed on the support base 2. The support plate 3 can support the flow meter body. Since the support plate 3 has an arc-shaped structure and is adapted to the shape of the inner wall of the flow meter body, the support plate 3 fits closely to the inner wall of the flow meter body, making its contact area larger, thus making the flow meter body more stable on the support plate 3. Then, the pressure plate 4 is pressed on the upper end of the flow meter body, and the first locking nut 7 is tightened, so that the flow meter body is tightly fixed between the pressure plate 4 and the support plate 3. The support rod 5 at one end of the pressure plate 4 is pressed against the base 1 at the same time to prevent the pressure plate 4 from shaking, and it can be more stable when drilling the flow meter body.

[0027] Furthermore, there are two symmetrically arranged support bases 2 on the base 1, and the support plate 3 is located between the two support bases 2, with both ends of the support plate 3 respectively mounted on the top of the two support bases 2. The support base 2 includes a vertical plate and a horizontal plate that are fixedly connected. The horizontal plate is set perpendicular to the vertical plate and can be detachably fixed on the upper surface of the base 1. The support plate 3 is mounted on the top of the vertical plate. During the drilling process, the flow meter body is located between the two support bases 2.

[0028] Furthermore, the clamping plate 4 and the support rod 5 are vertically arranged, the clamping plate 4 is horizontally arranged, the support rod 5 is vertically arranged, and the locking rod 6 is vertically arranged. One end of the locking rod 6 is fixedly connected to the base 1, and the other end extends through the clamping plate 4 to the top of the clamping plate 4. The outer wall of the locking rod 6 is provided with external threads, so the first locking nut 7 can be threadedly connected to the locking rod 6. The first locking nut 7 is located above the clamping plate 4 and is in contact with the upper end face of the clamping plate 4. During the tightening process of the first locking nut 7, it is possible to... The clamping plate 4 firmly fixes the flow meter body to the support plate 3. At the same time, the support rod 5 can support the end of the clamping plate 4 away from the flow meter body, and the support rod 5 can also be slightly tilted to make the clamping plate 4 more stable. Since the outer wall of the flow meter body is provided with a bottom shell for installing the probe, in order to avoid the bottom shell, the end of the clamping plate 4 away from the support rod 5 is a U-shaped structure. Therefore, one end of the clamping plate 4 is provided with two clamping rods, and the bottom shell can be set between the two clamping rods, so as to avoid the bottom shell on the meter body.

[0029] Furthermore, the clamping plate 4 is provided with a locking groove 8, and the locking rod 6 is slidably disposed in the locking groove 8. When the clamping plate 4 moves back and forth on the base 1, the locking rod 6 can slide in the locking groove 8, which can be applied to drilling holes in flow meter bodies of different sizes.

[0030] Furthermore, the base 1 has multiple parallel sliding grooves 9, which are T-shaped grooves. The lower end of the locking rod 6 is provided with a fixing block 10, which is slidably disposed in the sliding groove 9, so that the locking rod 6 and the pressing plate 4 can move along the length of the sliding groove 9 for position adjustment.

[0031] Furthermore, a slider 11 is fixedly provided at the bottom of the support base 2. The slider 11 is slidably disposed in the slide groove 9. During the installation of the support base 2 on the base 1, the slider 11 can limit the support base 2, so that the support base 2 can move along the length direction of the slide groove 9, thereby making the position of the support base 2 more accurate and improving the drilling accuracy.

[0032] Furthermore, a locking bolt 12 is inserted into the support base 2. The locking bolt 12 is located on the horizontal plate of the support base 2. The locking bolt 12 includes a nut portion 13 and a screw portion 14. The nut portion 13 is slidably disposed in the sliding groove 9. The screw portion 14 is inserted into the horizontal plate of the support base 2 and its upper end extends above the horizontal plate. A second locking nut 15 is threaded onto the screw portion 14. The second locking nut 15 abuts against the upper surface of the horizontal plate of the support base 2. After the second locking nut 15 is tightened, the support base 2 can be fixed on the base 1.

[0033] Furthermore, as shown in Figure 3, the support base 2 is provided with a connecting groove 16, which is located on the upper surface of the vertical plate of the support base 2. The support plate 3 is slidably disposed in the connecting groove 16. During the installation of the watch body, the watch body is first placed between the two support bases 2, and then the support plate 3 is slid along the connecting groove 16 so that the support plate 3 is inserted into the inner hole of the watch body to support the watch body until both ends of the support plate 3 are supported on the two support bases 2.

[0034] Furthermore, since there are two support bases 2, the connecting groove 16 on one support base 2 passes through the upper end face of the support base 2, and the connecting groove 16 of the other support base 2 is provided with a baffle. The support plate 3 can slide along the connecting groove 16 that passes through the support base 2 until one end of the support plate 3 slides into the connecting groove 16 of the other support base 2 and abuts against the baffle. The baffle can limit and position the support plate 3, so that the position of the support plate 3 is consistent each time it is installed, thereby improving the drilling accuracy.

[0035] Furthermore, the support plate 3 is provided with a positioning hole 17, which is a drilling point. After the drill bit penetrates the dial indicator, it can be inserted into the positioning hole 17 to prevent the drill bit from suddenly contacting the support plate 3 and damaging the drill bit.

[0036] Furthermore, a lower support block 18 is fixedly provided on the support base 2. The lower support block 18 is fixed to one side of the support base 2 by welding. An upper support block 19 is provided on the lower support block 18. The lower support block 18 and the upper support block 19 are in sliding contact. Both the lower support block 18 and the upper support block 19 are wedge-shaped structures. The lower end face of the lower support block 18 is a plane and is parallel to the upper end face of the base 1. The upper end face of the lower support block 18 is an inclined plane. The upper end face of the upper support block 19 is a plane and is parallel to the upper end face of the base 1. The lower end face of the upper support block 19 is an inclined plane. The inclined surface of the upper support block 19 abuts against the inclined surface of the lower support block 18. Both the lower support block 18 and the upper support block 19 are located below the flow meter body, and the upper end face of the upper support block 19 abuts against the flow meter body, thus supporting the flow meter body. During use, after the flow meter body is mounted on the support plate 3, the clamping plate 4 presses the upper end of the flow meter body, and at the same time, the first locking nut 7 is turned. After a certain force is applied, the position angle of the flow meter body can be finely adjusted by the upper support block 19 sliding on the lower support block 18. After the adjustment is completed, the first locking nut 7 is tightened.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
