Description
Technical Field
[0001] The present application relates to the technical field of detecting the angles of water inlets and outlets of a watch case, and in particular to a tool for detecting the angles of water inlets and outlets of a watch case. Background Art
[0002] In a single-jet water meter, the water flow through the water inlet directly drives the impeller to rotate, and then flows out from the water outlet. The angle of the water inlet and outlet of the meter case controls the flow direction of the water inside the meter case, which is closely related to the speed of the impeller rotation and has a significant impact on the metering performance of the water meter. Therefore, it is necessary to control the angle of the water inlet and outlet to improve the pass rate of the water meter performance test and accurate measurement.
[0003] Since the water inlet and outlet are inside the case, it is not easy to measure them using general measuring instruments such as angle measuring instruments. Using three-coordinate measurement is time-consuming and costly, which is not suitable for the rapid measurement requirements of the production site, so further improvement is needed. Utility Model Content
[0004] In order to conveniently detect the angles of the water inlet and outlet of the watch case, the present application provides a tool for detecting the angles of the water inlet and outlet of the watch case.
[0005] This application provides a tool for detecting the angle of the water inlet and outlet of a watch case, which adopts the following technical solution:
[0006] A tool for detecting the angles of the water inlet and outlet of a water meter case, comprising a first stopper rod inserted into the water inlet of the water meter case, a second stopper rod inserted into the water outlet of the water meter case, and a measuring block slidably inserted into the top opening of the water meter, wherein opposite side walls of the measuring block are respectively provided with a first slot and a second slot, the first stopper rod is used to be slidably inserted into the first slot, and the second stopper rod is used to be slidably inserted into the second slot.
[0007] By adopting the above technical solution, the measuring block is processed with the first slot and the second slot having the same angle as the water inlet and the water outlet according to the drawing. When the first stopper rod and the second stopper rod respectively pass through the water inlet and the outlet of the watch case and enter the inner cavity of the watch case, and if they can be successfully inserted into the first slot and the second slot of the measuring block respectively, it can be determined that the inlet and outlet angles on the watch case are in accordance with the drawing. If they cannot be inserted, it can be determined that the angles of the water inlet and outlet of the watch case do not conform to the drawing. By using the measuring block, the first stopper rod and the second stopper rod, the angles of the water inlet and outlet of the water meter case can be detected relatively conveniently, so that the operator can quickly check whether the angles of the water inlet and outlet conform to the drawing, thereby improving work efficiency. The tooling is easy to carry and can be conveniently used on the workbench on site. At the same time, the tooling is relatively easy to process and has a relatively low cost, so it can be put into use on a large scale.
[0008] Preferably, it further comprises a positioning pin, the measuring block is provided with a through hole for the positioning pin to slide through, the through hole is eccentrically arranged on the measuring block, and the bottom inner wall of the watch case is provided with a positioning hole for the positioning pin to be inserted.
[0009] By adopting the above technical solution, a positioning pin is provided, and after the positioning pin is inserted into the through-hole, the measuring block starts to be rotated. When it is rotated to align with the positioning hole on the case, the positioning pin is inserted into the positioning hole to position the measuring block so that the axes of the first slot and the second slot are set relative to the angles of the water inlet and outlet set on the drawing, so that when the first stopper rod and the second stopper rod are respectively inserted, it indicates that the angles of the water inlet and outlet of the case meet the standards.
[0010] Preferably, a spring is provided on the outer coaxial sleeve of the positioning pin, the lower end of the spring is fixedly connected to the upper surface of the measuring block, the upper end of the spring is fixedly connected to a fixing plate, the fixing plate is fixedly connected to the positioning pin, and the spring forces the positioning pin to move toward the direction close to the positioning hole.
[0011] By adopting the above technical solution, a spring is provided. Since the diameter of the locating pin itself is relatively small, it is relatively difficult to align the locating pin manually when inserting it into the locating hole. At this time, by providing the spring, when the measuring block is rotated, if the through hole and the locating hole are aligned, the locating pin slides and is inserted into the locating hole under the action of the spring, and the positioning between the measuring block and the watch case is relatively fast, thereby limiting the rotation of the measuring block so that the first stopper rod and the second stopper rod can be inserted later.
[0012] Preferably, an observation port is provided through the upper surface of the measuring block, and two observation ports are provided and are respectively arranged on both sides of the first slot and the second slot, and the observation ports extend to the outer peripheral wall of the measuring block.
[0013] By adopting the above technical solution, since two observation ports are provided, it is possible to check whether the first stopper rod and the second stopper rod are properly inserted and whether they are respectively inserted into the first slot and the second slot. The measuring block can also be slidably inserted into the watch case by pinching the observation ports on both sides to adjust the position of the measuring block. After the inspection is completed, the measuring block can be disassembled from the watch case.
[0014] Preferably, grooves are formed around the outer peripheral walls of the first stopper rod and the second stopper rod.
[0015] By adopting the above technical solution, grooves are provided on the first stopper rod and the second stopper rod, so as to check whether the first stopper rod and the second stopper rod are properly inserted, thereby reducing the possibility of errors in the results of judgment due to improper insertion.
[0016] Preferably, the groove is provided at the connection between the first stopper rod and the second stopper rod exposed outside the watch case and inserted into the watch case.
[0017] By adopting the above technical solution, compared with providing the groove at one end of the first stopper rod and the second stopper rod inserted into the watch case and viewing the groove through the observation port, providing the groove at the connection between the first stopper rod and the second stopper rod exposed outside and inserted into the watch case, after the first stopper rod and the second stopper rod are fully inserted, the groove is covered by the watch case, thereby making it relatively easier to view.
[0018] Preferably, the first stopper rod and the second stopper rod are coaxially sleeved with second abutment plates, and the two second abutment plates are respectively used to abut against the end faces at the water inlet and the water outlet of the watch case.
[0019] By adopting the above technical solution and providing a second abutment plate, when the first stopper rod and the second stopper rod are inserted into the slot and the second slot, it is checked whether the two second abutment plates abut against the end faces of the water inlet and outlet respectively. If they abut, it is judged that they are fully inserted, that is, the watch case meets the processing standards. If they do not abut, it is judged that the watch case does not meet the processing standards.
[0020] Preferably, the outer wall of the measuring block is provided with a first abutment plate around its own axis, and the inner wall of the watch case is provided with a limiting ring above the water inlet and the water outlet for abutment by the first abutment plate.
[0021] By adopting the above technical solution, the abutment between the first abutment plate and the limiting ring is provided to limit the depth of the measuring block extending into the watch case, thereby reducing the length of the measuring block that needs to be provided.
[0022] Preferably, it further comprises a positioning plate, wherein the positioning plate is provided with a slot for the watch case to be inserted, and the depth of the slot is smaller than the distance between the bottom surface of the watch case and the water inlet and the water outlet.
[0023] By adopting the above technical solution, a slot is provided on the positioning plate to initially position the watch case, thereby reducing the possibility of shaking during the process of inserting the first stopper rod and the second stopper rod.
[0024] In summary, the present invention has the following beneficial effects:
[0025] The first stopper rod and the second stopper rod are respectively passed through the water inlet and outlet of the meter case and into the inner cavity of the meter case. If they can be successfully inserted into the first slot and the second slot of the measuring block respectively, it can be determined that the inlet and outlet angles on the meter case are in accordance with the drawing. If they cannot be inserted, it can be determined that the angles of the water inlet and outlet of the meter case do not conform to the drawing. The measuring block, the first stopper rod and the second stopper rod can relatively conveniently detect the angles of the water inlet and outlet of the water meter case, so that the operator can quickly check whether the angles of the water inlet and outlet conform to the drawing, thereby improving work efficiency. The tooling is easy to carry and can be conveniently used on the workbench on site. At the same time, the tooling is relatively easy to process and the cost is relatively low, so it can be put into use in large quantities. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-7 , further details of this application are given.
[0035] An embodiment of the present application discloses a tool for detecting the angles of a water inlet and outlet of a watch case.
[0036] Example 1:
[0037] A tool for detecting the angle of the water inlet and outlet of the watch case, referring to Figure 1 、 Figure 2 , including a first stopper rod 2 inserted into the water inlet 11 of the watch case 1, a second stopper rod 3 inserted into the water outlet 12 of the watch case 1, a measuring block 4 slidably inserted into the top opening of the watch case 1, and a positioning pin 5 passing through the measuring block 4.
[0038] The outer wall of the measuring block 4 is provided with a first abutting plate 41 around its own axis, and the inner wall of the watch case 1 is provided with a limiting ring 13 above the water inlet 11 and the water outlet 12 for the first abutting plate 41 to abut.
[0039] Reference Figure 1 、 Figure 3 The measuring block 4 has two opposing walls formed with a first slot 42 and a second slot 43, respectively. The first slot 42 and the second slot 43 are machined according to the drawings at the same angle as the water inlet 11 and the water outlet 12. Both the first slot 42 and the second slot 43 extend to the bottom wall of the measuring block 4. The first stopper rod 2 is slidably inserted into the first slot 42, and the second stopper rod 3 is slidably inserted into the second slot 43. In this embodiment, the upper surface of the measuring block 4 is provided with two observation ports 44, one on each side of the first slot 42 and the other slot 43. The observation ports 44 extend to the outer peripheral wall of the measuring block 4.
[0040] Among them, the outer peripheral walls of the first stopper rod 2 and the second stopper rod 3 are both provided with a groove 6, which can be set at one end of the first stopper rod 2 and the second stopper rod 3 inserted into the watch case 1, or the groove 6 can be set at the connection between the first stopper rod 2 and the second stopper rod 3 exposed in the watch case 1 and inserted in the watch case 1. The specific setting is based on the needs. In this embodiment, the groove 6 is specifically set at the connection between the first stopper rod 2 and the second stopper rod 3 exposed in the watch case 1 and inserted in the watch case 1, and the distance between the groove 6 and the first stopper rod 2 and the second stopper rod 3 is specifically processed according to the length of the water inlet 11 and the water outlet 12 of the watch case 1 on the processing drawing.
[0041] Reference Figure 2 、 Figure 4 , wherein, for the locating pin 5, in this embodiment, a through-hole 45 is provided through the measuring block 4 for the locating pin 5 to slide through, the through-hole 45 is eccentrically arranged on the measuring block 4, and a locating hole 14 is provided on the bottom inner wall of the watch case 1 for the locating pin 5 to be inserted.
[0042] The implementation principle of a tool for detecting the angle of the water inlet and outlet of a watch case in an embodiment of the present application is: after the positioning pin 5 is inserted into the through-hole 45, the measuring block 4 is started to be rotated. When it is rotated to align with the through-hole 45 and the positioning hole 14 on the watch case 1, the positioning pin 5 is inserted into the positioning hole 14 to position the measuring block 4. Then, the first stopper rod 2 and the second stopper rod 3 are respectively passed through the water inlet and outlet 12 of the meter case 1 and into the inner cavity of the meter case 1. If they can be smoothly inserted into the first slot 42 and the second slot 43 of the measuring block 4, it can be determined that the inlet and outlet angles on the meter case 1 are in accordance with the drawing. If they cannot be inserted, it can be determined that the angles of the water inlet and outlet 12 of the meter case 1 are not in accordance with the drawing. By using the measuring block 4, the first stopper rod 2 and the second stopper rod 3, it is relatively convenient to detect the angles of the water inlet and outlet 12 of the water meter case 1, so that the operator can quickly check whether the angles of the water inlet and outlet 12 are in accordance with the drawing, thereby improving work efficiency. The tooling is easy to carry and can be conveniently used on a workbench on site. At the same time, the tooling is relatively easy to process and has a relatively low cost, so it can be put into use in large quantities.
[0043] Example 2:
[0044] Reference Figure 5 The difference from Example 1 is that a spring 51 is coaxially sleeved outside the positioning pin 5, the lower end of the spring 51 is fixedly connected to the upper surface of the measuring block 4, the upper end of the spring 51 is fixedly connected to a fixing plate 52, the fixing plate 52 is fixedly connected to the positioning pin 5, and the spring 51 forces the positioning pin 5 to move toward the direction close to the positioning hole 14.
[0045] Example 3:
[0046] Reference Figure 6 、 Figure 7 , which differs from Example 1 in that it further includes a positioning plate 7 having a slot 71 for engaging the watch case 1. The depth of the slot 71 is less than the distance between the bottom surface of the watch case 1 and the water inlet 11 and the water outlet 12. Furthermore, the first stopper rod 2 and the second stopper rod 3 are coaxially sleeved with second abutment plates 8, which are respectively configured to abut the end surfaces of the watch case 1 at the water inlet 11 and the water outlet 12.
