Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling technology, and in particular to a laser engraving positioning tooling for water meters. Background Technology

[0002] As we all know, with the rapid development of modern industry, the coverage of urban water supply has become wider and wider, allowing users to directly draw water at home. Currently, water meters are generally used to calculate the water consumption of each household. A water meter is an instrument that measures water flow. It is generally composed of an outer casing and various instrument parts set inside the casing, and is assembled by covering the outer casing with a water meter cover.

[0003] Currently, when manufacturing water meters, existing manufacturers usually need to engrave the water meter serial number on the water meter to facilitate subsequent identification of each water meter. The common engraving method is laser engraving, which uses lasers to engrave characters or barcodes on the water meter.

[0004] In current technologies, laser engraving processes typically require manual loading and unloading, and often involve laser engraving the dial of a water meter to create the desired characters or barcodes. During manual loading and unloading, the meter's dial is usually placed face up to ensure it is horizontal. Once the laser engraving is complete, the meter is unloaded.

[0005] Research has found that the laser engraving process described above relies on manual operation, which is prone to errors when loading and unloading multiple water meters. This can result in the water meter dials not being placed horizontally or facing the laser engraving machine directly, leading to inconsistent laser engraving effects in a large batch of water meters during production. This results in a high scrap rate and impacts the production process, as the quality of the laser engravings cannot meet the delivery requirements. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a water meter laser engraving positioning fixture to overcome the problem of inconsistent laser engraving effects caused by the inability of the water meter dial to be placed horizontally and directly facing the laser engraving machine when manually installing water meters.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a water meter laser engraving positioning fixture, which includes a horizontal fixing plate, characterized in that the horizontal fixing plate is provided with a first positioning component and a second positioning component, and the first positioning component and the second positioning component have a distance in a first direction;

[0008] The first positioning member has a first mounting slot on the side near the second positioning member. The first mounting slot extends vertically through the first positioning member, and the upper surface of the first positioning member is horizontal.

[0009] Furthermore, in the water meter laser engraving positioning fixture of this utility model, the second positioning component includes at least two supporting positioning components, and two adjacent supporting positioning components have a distance between them in a second direction perpendicular to the first direction.

[0010] Furthermore, in the water meter laser engraving positioning fixture described in this utility model, a second mounting slot is provided at the top of the supporting positioning component.

[0011] Furthermore, in the water meter laser engraving positioning fixture described in this utility model, the second mounting slot is an arc-shaped slot.

[0012] Furthermore, in the water meter laser engraving positioning fixture described in this utility model, a retaining edge is provided on one side of the second mounting slot.

[0013] Furthermore, in the water meter laser engraving positioning fixture of this utility model, the first positioning component includes a column and a mounting plate. The column extends vertically, and the mounting plate is horizontally positioned. One end of the column is connected to a horizontal fixing plate, and the other end is connected to the mounting plate.

[0014] Furthermore, in the water meter laser engraving positioning fixture described in this utility model, the first mounting slot is provided to penetrate the mounting plate in the vertical direction.

[0015] Furthermore, in the water meter laser engraving positioning fixture described in this utility model, the first mounting slot is a semi-circular slot.

[0016] Furthermore, the water meter laser engraving positioning fixture of this utility model includes at least two columns, which are spaced apart in a second direction perpendicular to the first direction, and the first mounting slot is located between two adjacent columns.

[0017] Furthermore, in the water meter laser engraving positioning fixture described in this utility model, the upper surface of the first positioning component is also provided with an adhesive layer, which is arranged around the first mounting groove.

[0018] The beneficial effects of this utility model are as follows: The water meter laser engraving positioning fixture provided by this utility model sets a first positioning component and a second positioning component on a horizontal fixed plate. The first mounting slot of the first positioning component effectively matches and accommodates the base body of the water meter. Thus, the horizontal upper surface of the first positioning component supports the base body of the water meter, and the second positioning component supports the electronic control body of the water meter. This ensures that the water meter is placed horizontally when it is manually placed, thus overcoming the problem of inconsistent laser engraving effects caused by the inability of the water meter's dial to be placed horizontally and facing the laser engraving machine during existing manual water meter installation. This facilitates subsequent laser engraving on the upper surface of the water meter.

[0019] Therefore, the water meter laser engraving positioning fixture of this utility model can greatly simplify the manual loading work before laser engraving of water meters. It can avoid the problem of water meters not being placed horizontally due to manual loading, and avoid the problem of inconsistent laser engraving effects in the production of large batches of water meters. While simplifying the difficulty of manual operation, it can reduce the high product scrap rate and speed up the production process. It has good promotion prospects and application value.

[0029] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Research has found that the laser engraving process of existing water meters 1 relies on manual operation. When multiple water meters 1 are loaded and unloaded manually, errors are easily made, causing the dial of the water meter 1 to be unable to be placed horizontally or aligned with the laser engraving machine. As a result, a large number of water meters 1 are prone to inconsistent laser engraving effects during the production process, which cannot meet the delivery requirements, leading to a high scrap rate and affecting the production process.

[0031] Based on this, please refer to Figures 1 to 3This utility model designs a new water meter laser engraving positioning fixture, which places the water meter 1 on the water meter laser engraving positioning fixture before the water meter 1 is manually loaded and laser engraved, thereby helping to achieve the horizontal placement of the water meter 1.

[0032] For ease of understanding, see Figure 1 As shown, a common water meter 1 is disclosed, which specifically includes a base meter body 11 and an electronic control body 12. The electronic control body 12 is detachably fixedly installed on the base meter body 11, that is, it is specifically installed on the dial cover of the base meter body 11 and protrudes from the base meter body 11.

[0033] Based on the structure of this water meter 1, the water meter laser engraving positioning fixture specifically designed in this utility model includes: a horizontal fixing plate 2 and a first positioning member 3 and a second positioning member disposed on the horizontal fixing plate 2. The first positioning member 3 and the second positioning member are spaced apart in a first direction. The first positioning member 3 is provided with a first mounting slot 31 on the side near the second positioning member. The first mounting slot 31 is disposed through the first positioning member 3 in a vertical direction, and the upper surface of the first positioning member 3 is horizontal.

[0034] As can be seen from the above description, the beneficial effects of this utility model are as follows: the water meter laser engraving positioning fixture sets a first positioning component 3 and a second positioning component on the horizontal fixed plate 2, so that the first mounting slot 31 of the first positioning component 3 can effectively match and accommodate the base meter body 11 of the water meter 1, that is, part of the base meter body 11 can be supported by the horizontal upper surface of the first positioning component 3. At the same time, the second positioning component supports the electronic control body of the water meter 1, so as to ensure that the water meter 1 is placed horizontally when manually placed, and overcomes the problem of inconsistent laser engraving effect of the water meter 1 caused by the inability of the dial of the water meter 1 to be placed horizontally and facing the laser engraving machine when manually installing the water meter 1. This facilitates the subsequent laser engraving of the upper surface of the water meter 1.

[0035] In other words, in practical applications, when manually loading the water meter 1, the dial surface of the base body 11 of the water meter 1 can be controlled to face upwards, and the base body 11 can be placed vertically into the first mounting slot 31 of the first positioning member 3. Figure 1 The outer diameter of the base meter body 11 shown is not uniform in the vertical direction. Therefore, the water meter cover with a larger outer diameter will contact the horizontal upper surface of the first positioning member 3 and be supported by the first positioning member 3. At the same time, in order to ensure the stability and reliability of the positioning, the second positioning member with a certain distance from the first positioning member 3 is used to support the electronic control body 12 that protrudes from the base meter body 11, so as to ensure that the upper surface of the electronic control body 12 remains horizontal.

[0036] Furthermore, the aforementioned second positioning element includes at least two supporting positioning elements 4, and adjacent supporting positioning elements 4 have a distance between them in a second direction perpendicular to the first direction.

[0037] See Figure 1 As shown, in some embodiments, the first direction can be specifically selected as the horizontal length direction of the horizontal fixing plate 2, and the second direction can be specifically selected as the horizontal width direction of the horizontal fixing plate 2. In the above technical solution, two support positioning members 4 are provided and the two support positioning members 4 are spaced apart from each other so that the two support positioning members 4 can support the electronic control body 12 at two different points at the same time, thereby improving the stability of installation and positioning.

[0038] Furthermore, the top of the aforementioned support positioning member 4 is provided with a second mounting slot 41.

[0039] Furthermore, the second mounting slot 41 mentioned above is an arc-shaped slot.

[0040] In the above technical solution, in order to ensure that the support positioning member 4 can effectively support the electronic control body 12, considering the shape of the electronic control body 12 and the circular shape of its protruding part in the second direction when the electronic control body 12 is installed, a second mounting slot 41 is provided at the top of each support positioning member 4, and the second mounting slot 41 is set as an arc-shaped slot for adaptive matching.

[0041] Furthermore, a retaining edge 42 is provided on one side of the aforementioned second mounting slot 41.

[0042] In the above technical solution, to prevent the portion of the electrical control body 12 of the water meter 1 extending into the second mounting slot 41 of the support positioning member 4 from shifting or becoming loose; see... Figure 3 As shown, in some embodiments, a retaining edge 42 is provided on the side away from the gap between two adjacent support positioning members 4 to limit the electric body of the water meter 1.

[0043] Furthermore, the first positioning component 3 includes a column 32 and a mounting plate 33. The column 32 extends vertically, and the mounting plate 33 is horizontally positioned. One end of the column 32 is connected to the horizontal fixing plate 2, and the other end is connected to the mounting plate 33.

[0044] In the above technical solution, in order to improve the support stability of the first positioning component 3, in practical application, a column 32 can be set to support the mounting plate 33, thereby effectively supporting the base body 11 of the water meter 1.

[0045] Furthermore, the aforementioned first mounting slot 31 is provided to penetrate the mounting plate 33 in the vertical direction.

[0046] Furthermore, the first mounting slot 31 mentioned above is a semi-circular slot.

[0047] In the above technical solution of this utility model, in order to effectively match the base body 11 of the water meter 1, considering that the outer circumference of the existing base body 11 and its water meter cover are both circular, the first mounting slot 31 is specifically set to penetrate the mounting plate 33 in the vertical direction, and the first mounting slot 31 is controlled to be a semi-circular slot.

[0048] Furthermore, it includes at least two of the columns 32, which are spaced apart in a second direction perpendicular to the first direction, and the first mounting slot 31 is provided between two adjacent columns 32.

[0049] To ensure that the first positioning component 3 does not collide with the base body 11 of the water meter 1 when it is installed, the two columns 32 are spaced apart in the second direction, that is, in the width direction of the horizontal fixing plate 2, so as to ensure that when the water meter cover of the base body 11 collidees with the horizontal upper surface of the mounting plate 33, the components below the water meter cover can be properly placed between the spacing of the two adjacent columns 32.

[0050] Furthermore, the upper surface of the first positioning member 3 is also provided with an attachment layer 5, which surrounds the first mounting slot 31.

[0051] In the above technical solution, in order to improve the contact effect between the base body 11 of the water meter 1 and the upper surface of the first positioning member 3, and to ensure that the base body 11 can be set horizontally when the first positioning member 3 supports the base body 11, an attachment layer 5 can also be provided on the upper surface of the first positioning member 3. The attachment layer 5 is controlled to surround the first mounting slot 31 so that when the upper surface of the first positioning member 3 supports the base body 11 of the water meter 1, the base body 11 of the water meter 1 can simultaneously abut against the attachment layer 5, thereby using the attachment layer 5 to achieve attachment, further restricting the contact state between the base body 11 and the first positioning member 3, and ensuring that the base body 11 of the water meter 1 is set horizontally.

[0052] For ease of understanding, the present invention also provides the following two specific embodiments for supplementary explanation:

[0053] Example 1: A laser engraving positioning fixture for a water meter includes a horizontal fixing plate 2. The horizontal fixing plate 2 has a first positioning component 3 and a second positioning component, with a distance between the first positioning component 3 and the second positioning component in a first direction. The first positioning component 3 has a first mounting slot 31 on its side near the second positioning component. The first mounting slot 31 penetrates the first positioning component 3 vertically, and the upper surface of the first positioning component 3 is horizontally positioned. The first direction refers to the horizontal length direction of the horizontal fixing plate 2.

[0054] In this embodiment, the first positioning member 3 includes a mounting plate 33 and two uprights 32. Both uprights 32 extend vertically and are spaced apart in a second direction perpendicular to the first direction, i.e., spaced apart in the horizontal width direction of the horizontal fixing plate 2. In this embodiment, one end of each upright 32 is connected to the horizontal fixing plate 2, and the other end is connected to the mounting plate 33. Each end of the mounting plate 33 in the second direction is connected to an upright 32, ensuring that the mounting plate 33 is horizontally positioned.

[0055] It should be noted that in this embodiment, the first mounting slot 31 is located between two adjacent columns 32, and the first mounting slot 31 extends through the mounting plate 33 in the vertical direction. The first mounting slot 31 is a semi-circular slot to ensure that it can effectively match the base body 11 of the water meter 1, thereby effectively supporting the base body 11 of the water meter 1 and ensuring that the base body 11 contacts the upper surface of the mounting plate 33, thereby achieving the horizontal setting of the base body 11.

[0056] Accordingly, in order to ensure the stability of the water meter 1 during installation and positioning, in this embodiment, the second positioning component is specifically provided, including two supporting positioning components 4. These two supporting positioning components 4 also have a spacing in the second direction (the horizontal width direction of the horizontal fixing plate 2). At the same time, the top of the supporting positioning component 4 is provided with a second mounting slot 41, which is specifically an arc-shaped slot. The arc-shaped slot is used to effectively match the shape of the electronic control body 12 of the water meter 1, thereby effectively supporting the electronic control body 12 of the water meter 1 and ensuring that the water meter 1 remains horizontal after being installed, supported, and positioned by the first positioning component 3 and the second positioning component.

[0057] Example 2:

[0058] See Figure 3 As shown, in this embodiment two water meter laser engraving positioning fixture, the basic structure of its horizontal fixing plate 2, first positioning component 3, and second positioning component is consistent with the structure of the water meter laser engraving positioning fixture in embodiment one. It should be emphasized that in this embodiment two water meter laser engraving positioning fixture, a retaining edge 42 is also provided on the second positioning component, and on the side away from the gap between two adjacent supporting positioning components 4, to limit the electric body of the water meter 1.

[0059] Meanwhile, in this second embodiment, an attachment layer 5 is also provided on the upper surface of the first positioning member 3, and the attachment layer 5 is controlled to surround the first mounting slot 31 so that when the upper surface of the first positioning member 3 supports the base body 11 of the water meter 1, the base body 11 of the water meter 1 can simultaneously abut against the attachment layer 5, thereby using the attachment layer 5 to achieve attachment, further restricting the contact state between the base body 11 and the first positioning member 3, and ensuring that the water meter 1 is set horizontally.

[0060] In summary, the water meter laser engraving positioning fixture provided by this utility model can greatly simplify the manual loading work before laser engraving of the water meter 1. It can avoid the problem of the water meter 1 not being placed horizontally due to manual loading, and avoid the problem of inconsistent laser engraving effects in a large batch of water meters 1 during production. While simplifying the difficulty of manual operation, it can reduce the high product scrap rate and speed up the production process. It has good promotion prospects and application value.

[0061] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
