Description

Technical Field

[0001] The utility model belongs to the technical field of sealing tooling, and more specifically relates to a tooling for controlling the thickness of a glue layer between test strips. Background Art

[0002] Common sealing methods include sealing rings and sealants. The traditional glue groove structure consists of a lower housing groove and an upper housing boss, with the groove and boss mating symmetrically. When glue is injected into the lower housing groove, when the upper housing boss mates with the lower housing groove, the glue will overflow evenly from the interior and exterior surfaces of the housing, resulting in a poor appearance. After curing, the glue is difficult to remove, resulting in a poor appearance. Removal requires increased labor and material costs, resulting in production waste and affecting product production schedules.

[0003] Corresponding improvements have also been made to address the above-mentioned problems, such as Chinese patent application number CN202311187689.9, published on September 15, 2023. This patent discloses a spline bonding auxiliary tooling, comprising two height guide assemblies, the two height guide assemblies being arranged in parallel, an action end being provided on the height guide assembly, the action end being connected to a horizontal clamping assembly perpendicular to the height adjustment assembly, the entirety of the action end and the horizontal clamping assembly being able to move up and down along the height guide assembly; the horizontal clamping assembly is used to clamp the clamping end set for the spline; wherein, by adjusting the height difference between the two horizontal clamping assemblies on the corresponding height guide assemblies, the target spacing between the adhesive surfaces set for the splines clamped by the two horizontal clamping assemblies is achieved. The disadvantage of this patent is that, although it can effectively control the thickness of the adhesive layer, it has a complex structure and high cost.

[0004] Another example is Chinese patent application number CN201821863462.6, published on June 18, 2019. This patent discloses a tooling that can precisely control the thickness of a bonding layer, including a fixture a, a fixture a*, a positioning device b, a positioning device b*, a guide rod c, a guide rod c*, and a mounting block. Both fixture a and fixture a* are multi-layer plate structures, used to respectively clamp the test pieces to be bonded. Positioning device b and positioning device b* are located below fixture a and fixture a*, respectively. The coarse adjustment push rod and fine adjustment push rod in positioning device b support fixture a, and the coarse adjustment push rod in positioning device b* supports fixture a*. The two coarse adjustment push rods can respectively achieve quantitative coarse adjustment of the height of fixture a and fixture a*, and the fine adjustment push rod can achieve quantitative fine adjustment of the height of fixture a, thereby precisely controlling the distance between the two test pieces to be bonded and achieving precise control of the thickness of the bonding layer. The shortcomings of this patent are: complex structure and cumbersome use. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The utility model provides two grooves on the bottom plate, and forms a height difference between the two grooves, so that the overlapping parts of the test specimens placed in the two grooves need to be glued to form a glue layer thickness, and the glue layer thickness can be maintained within a fixed numerical range, thereby achieving consistency in the glue layer thickness; at the same time, the two grooves are relatively parallel, which can ensure the parallelism of the two test specimens and facilitate the stability of subsequent tests; and the arrangement of the middle pressure plate and the side pressure plate makes the two test specimens have good stability after being glued, and is not prone to relative movement or external interference affecting subsequent tests; the entire tooling structure is simple, easy to manufacture and low in cost,

[0030] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, a tool for controlling the thickness of the adhesive layer between test specimens includes a base plate 1 with a first groove 11 and a second groove 12 formed on either side thereof. The first groove 11 and the second groove 12 are each used to accommodate a test specimen 7. The first groove 11 and the second groove 12 are arranged opposite and parallel to each other; the bottom of the first groove 11 is higher than the top of the second groove 12. For ease of understanding, the following definitions are used: the test specimen 7 in the first groove 11 is defined as the upper test specimen, and the test specimen 7 in the second groove 12 is defined as the lower test specimen. The first groove 11 and the second groove 12 are arranged opposite and parallel to each other because the upper and lower test specimens need to partially overlap, which requires adhesive bonding. The bottom of the first groove 11 is higher than the top of the second groove 12, creating a height difference between the two grooves. This height difference represents the adhesive thickness, or the adhesive layer thickness. Because this height difference is constant, the adhesive layer thickness between the two test specimens 7 remains consistent. That is to say, in this embodiment, the bottom of the first groove 11 is higher than the bottom of the second groove 12 by a distance equal to the thickness of the lower test specimen in the second groove 12 plus the thickness of the adhesive layer.

[0033] A removable intermediate pressure plate 3 is installed between the first groove 11 and the second groove 12; side pressure plates 2 are also removably installed on each of the first groove 11 and the second groove 12. It should be noted that after the two test strips 7 are bonded together, they need to be tested. During this process, the stability of the two test strips 7 must be maintained. Therefore, the installation of the intermediate pressure plate 3 and side pressure plates 2 ensures that the test strips 7 within the two grooves maintain a high degree of stability after bonding, making them less susceptible to external environmental influences and facilitating subsequent testing. The removable intermediate pressure plate 3 and side pressure plates 2 do not interfere with the bonding process between the two test strips 7. Once bonding is complete, the intermediate pressure plate 3 and side pressure plates 2 can be installed.

[0034] The utility model provides two grooves on the bottom plate 1, and forms a height difference between the two grooves, so that the test specimens 7 placed in the two grooves need to be glued to form a glue layer thickness that can be maintained within a fixed value range, thereby achieving consistency in the thickness of the glue layer; at the same time, the two grooves are relatively parallel, which can ensure the parallelism of the two test specimens 7 and facilitate the stability of subsequent tests; and the arrangement of the middle pressing plate 3 and the side pressing plates 2 ensures that the two test specimens 7 have good stability after being glued, and are not prone to relative movement or external interference that affects subsequent tests; the entire tooling structure is simple, easy to manufacture and low in cost.

[0035] like Figure 3 、 Figure 4 and Figure 5 As shown, in a specific embodiment, the base plate 1 includes a rectangular plate body 14. The rectangular plate body 14 has a regular shape and is easy to process and align on its surface. A first groove 11 and a second groove 12 are respectively provided on opposite sides of the plate body 14. A gasket 6 is provided in the second groove 12. Specifically, a countersunk hole 15 is provided in the second groove 12. The gasket 6 is placed in the countersunk hole 15. The countersunk hole 15 is adapted to the size of the gasket 6. The countersunk hole 15 limits the gasket 6 and ensures the stability of the gasket 6 in the second groove 12. The setting position of the gasket 6 corresponds to the overlapping position of the two test specimens 7 placed in the first groove 11 and the second groove 12. That is, because there is an overlapping area between the two test specimens 7 in the first groove 11 and the second groove 12, a gasket 6 is provided at the position corresponding to the overlapping area, that is, the overlapping area is accumulated on the surface of the gasket 6. The provision of the gasket 6 prevents the overlapping adhesive portion from being deformed or damaged due to excessive pressure during the subsequent pressing process of the intermediate pressing plate 3, and also ensures that the two test specimens 7 can form an ideal contact surface during gluing, thereby ensuring the gluing effect.

[0036] In one embodiment, the plate body 14 is further provided with a third groove 13, which is provided between the first groove 11 and the second groove 12, with the top of the third groove 13 being lower than the bottom of the first groove 11. The third groove 13 is a glue flow groove. When the two test specimens 7 in the first groove 11 and the second groove 12 are bonded and then squeezed by the intermediate pressing plate 3, some of the glue will overflow. Since the first groove 11 is higher than the second groove 12, during the actual squeezing process, the glue will flow to one side of the first groove 11. Therefore, the third groove 13 is provided on one side of the first groove 11 to form a height difference with the first groove 11, so that the glue can flow to the third groove 13. The overflowed glue can be stored in the third groove 13, preventing the glue from spreading all over the plate body 14 and causing difficulties in subsequent cleaning.

[0037] In one specific embodiment, the plate body 14 is provided with mounting holes for mounting the side pressure plates 2 on the sides provided with the first groove 11 and the second groove 12, respectively. The side pressure plates 2 are provided with holes at positions corresponding to the mounting holes, and the fasteners 5 pass through the holes on the side pressure plates 2 and the mounting holes on the plate body 14 to achieve the installation of the side pressure plates 2. The plate body 14 is provided with fixing holes for mounting the intermediate pressure plates 3 at a position between the first groove 11 and the second groove 12. The intermediate pressure plates 3 are provided with holes at positions corresponding to the fixing holes, and the fasteners 5 pass through the holes on the intermediate pressure plates 3 and the fixing holes on the plate body 14 to achieve the installation of the intermediate pressure plates 3. The fasteners 5 here can be simple components such as fastening screws or fastening bolts, and have a good fastening effect.

[0038] In one embodiment, a plurality of first grooves 11 and second grooves 12 are provided. This configuration allows for simultaneous bonding of multiple groups of test strips 7, improving work efficiency. Furthermore, the width and depth of the first grooves 11 and 12 are identical. Because both the first and second grooves 11 and 12 are used to accommodate the test strips 7, the test strips 7 have identical shapes and dimensions, with the width and thickness of the test strips 7 being the same as the groove width and the depth of the groove, ensuring the secure placement of the test strips 7 within the grooves. Designing the first and second grooves 11 and 12 to be identical in size facilitates placement of the test strips 7 and facilitates batch production. It also helps ensure the accurate positioning of the two test strips 7 during the gluing process, reducing operational complexity and thus improving work efficiency.

[0039] Specifically, in this embodiment, the depth of the first groove 11 is 1.0±0.02 mm, and the width of the first groove 11 is 25.1±0.02 mm; the depth and width of the second groove 12 are the same as those of the first groove 11. Specific limits on the width and depth of the first and second grooves 11, 12 facilitate processing while ensuring the placement of the test strip 7. Furthermore, because the test strip 7 within the first groove 11 and the test strip 7 within the second groove 12 will partially overlap, the overlapping portion needs to be glued to form a glue layer. The thickness of this glue layer is controlled to be 0.2±0.02 mm, and the length of the overlapping portion is controlled to be 12.5±0.5 mm, ensuring both bonding strength and improving bonding efficiency.

[0040] In one embodiment, the surfaces of the intermediate pressure plate 3, the side pressure plates 2, and the bottom plate 1 are each provided with a protective layer. The protective layer protects the intermediate pressure plate 3, the side pressure plates 2, and the bottom plate 1, preventing them from deteriorating due to long-term exposure to the external environment. Specifically, the intermediate pressure plate 3, the side pressure plates 2, and the bottom plate 1 are made of 45# steel, which is strong and has high strength. The protective layer is galvanized on the surface of the 45# steel, which effectively prevents the intermediate pressure plate 3, the side pressure plates 2, and the bottom plate 1 from rusting, thereby increasing the service life of the components and saving maintenance costs.

[0041] In one embodiment, at least one side of the base plate 1 is provided with a handle 4. The provision of the handle 4 facilitates the transport of the entire tooling, allowing workers to move it anytime and anywhere. Specifically, in this embodiment, two handles 4 are provided, symmetrically arranged on two sides of the base plate 1, allowing workers to carry the tool with both hands, reducing labor while ensuring stable handling. Furthermore, this side is not the side where the first groove 11 and the second groove 12 are provided, thus preventing interference between components or damage to the first groove 11 or the second groove 12, thereby facilitating installation on the base plate 1.

[0042] The examples described in the present invention are merely descriptions of the preferred implementation methods of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should fall within the scope of protection of the present invention.
