Description

Technical Field

[0001] The utility model belongs to the technical field of bonding tooling, in particular to a bonding tooling for a tensile test piece. Background Art

[0002] The tensile test bonding tooling can improve the flatness of the ends of the reinforcing plates required for testing and the uniform pressure transmission, prevent glue overflow and uneven glue layer thickness, and prevent the main test plate from bending after curing.

[0003] Currently, the most common bonding process is manual marking and visual bonding. This method has the following limitations or shortcomings: 1. The two reinforcing plates at the upper and lower ends of the test plate are not flush; 2. The pressure is not evenly transmitted, and the test plate is easy to bend, resulting in serious glue overflow and uneven glue layer thickness. After forming, the glue overflowing from the test plate is difficult to clean. Utility Model Content

[0004] In order to solve the technical problem in the background technology that the specimen main board and the reinforcement sheet are difficult to be accurately bonded, the purpose of the utility model is to provide a tensile specimen bonding tool that can solve the above problem.

[0005] The technical solution to achieve the purpose of the utility model is: a tensile specimen bonding tool, including a base plate and a positioning block fixed on the base plate, the base plate is provided with a positioning boss, the positioning boss has a profile corresponding to the reinforcement sheet, and is used to position the reinforcement sheet; there are at least two positioning blocks, which are respectively located on both sides of the positioning boss; the reinforcement sheet is located between the positioning boss and the positioning block.

[0006] When gluing the specimen main board and the reinforcing sheet, first place the reinforcing sheet between the positioning block and the positioning boss. Since the positioning boss has a profile structure corresponding to the reinforcing sheet, that is, the profile of the positioning boss has a positioning effect on the reinforcing sheet, and then the positioning block is used to abut against the other end of the reinforcing sheet, which limits the reinforcing sheet. Then, an adhesive film is pasted on the reinforcing sheet, and the specimen main board is placed on it to complete the accurate bonding of the specimen main board and the reinforcing sheet. At least two positioning blocks are respectively located on both sides of the positioning boss, and reinforcing sheets can be placed on both sides of the positioning boss at the same time to complete the bonding at both ends of the specimen main board. The limited area of ​​the limit block can also limit the specimen main board, and further, the reinforcing sheet can continue to be bonded above the specimen main board, and the positioning is completed by only abutting against the positioning block.

[0007] Furthermore, the end of the reinforcing sheet is provided with a first inclined surface, and the profile is a second inclined surface corresponding to the first inclined surface. The first inclined surface and the second inclined surface correspond to each other and can be spliced ​​into a rectangular shape. The structure and principle are simple, and the positioning of the reinforcing sheet under the specimen mainboard is quickly completed.

[0008] Furthermore, the second inclined surface extends outward from the positioning boss body, and its height gradually decreases. The first inclined surface and the second inclined surface are arranged opposite to each other, and the two are combined to form a rectangular structure, so that positioning can be completed quickly.

[0009] Furthermore, a limiting step is provided between the second inclined surface and the main body of the positioning boss, and the edge of the first inclined surface abuts against the limiting step. In order to prevent the first inclined surface from sliding, dislocating, and other problems again after being spliced ​​onto the second inclined surface, the limiting step can limit the sliding of the first inclined surface along the second inclined surface, and the other end of the reinforcing sheet is limited by the positioning block, so that the reinforcing sheet is fixed and will not slide or dislocate.

[0010] Furthermore, the height of the first bevel is not greater than the height of the second bevel. For example, if the height of the second bevel is 6 mm, the height of the first bevel is 4-6 mm. This is because the bevel and the end of the reinforcing plate are formed by CNC, and the machining tolerance is ±1 mm. The tolerance of the gluing tooling mold is different, otherwise there will be interference, and the lower end reinforcing plate will not fit into the slot and get stuck.

[0011] Furthermore, it also includes a pressure plate, the reinforcing sheet includes an upper reinforcing sheet and a lower reinforcing sheet, the lower reinforcing sheet is located below the end of the specimen main board and is limited between the positioning boss and the positioning block, the upper reinforcing sheet is located above the end of the specimen main board, and the pressure plate is pressed above the upper reinforcing sheet. Specifically, the lower reinforcing sheet is limited by the positioning block and the limiting step and will not move; while the upper reinforcing sheet fixed above the end of the specimen main board may move during the curing process. After adding a pressure plate above the upper reinforcing sheet, the problem of slippage will not occur due to the pressure of the pressure plate. After applying an adhesive film between the reinforcing sheet and the specimen main board and bonding them to each other, a release agent is applied to the pressure plate and pressed above the upper reinforcing sheet, and finally, vacuum compaction is performed by bag making, and the pressure plate is removed to obtain a reinforcing sheet bonded to both ends of the specimen main board above and below.

[0012] Furthermore, the height of the limit block is greater than the height of the pressure plate, that is, the pressure plate is also within the limiting area enclosed by the limit block, which not only limits the pressure plate, but also further ensures that the pressure plate will not move and the upper reinforcement plate pressed by the pressure plate will not slip.

[0013] Furthermore, the positioning block is a detachable structure. For example, there is a first mounting hole on the positioning block, and the base plate has a second mounting hole corresponding to the first mounting hole, and there are multiple second mounting holes. When the position of the positioning block needs to be adjusted, it is only necessary to match the first mounting hole to the appropriate second mounting hole and then insert the bolt.

[0014] Furthermore, a lifting ring is installed on the bottom plate to facilitate the suspension and movement of the bonding tool.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] (1) Positioning blocks and positioning bosses are arranged on the bottom plate to complete the positioning and limiting of the lower reinforcing sheet, and then the lower reinforcing sheet can be spliced ​​with the specimen main board after being coated with adhesive film, and the upper reinforcing sheet is positioned after being abutted against the positioning blocks, and then the upper reinforcing sheet can be spliced ​​with the specimen main board after being coated with adhesive film. The upper and lower reinforcing sheets are accurately positioned and installed after using this tooling;

[0017] (2) Add a pressure plate above the upper reinforcing plate to prevent the upper reinforcing plate from slipping;

[0018] (3) A second inclined surface corresponding to the first inclined surface on the reinforcing plate is provided on the positioning boss, and the two can be spliced ​​into a rectangular structure, which can quickly achieve positioning;

[0019] (4) a limiting step is provided on the second inclined surface to prevent the first inclined surface from sliding along the second inclined surface;

[0020] (5) The positioning block is detachable from the base plate and can be adjusted in position as required. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] Example:

[0029] like Figure 1-Figure 5 As shown, this embodiment provides a tensile specimen bonding tool, including a base plate 1 and a positioning block 2 fixed on the base plate 1, the base plate 1 is provided with a positioning boss 3, the positioning boss 3 has a profile corresponding to the reinforcing sheet, which is used to position the reinforcing sheet; there are at least two positioning blocks 2, which are respectively located on both sides of the positioning boss 3; the reinforcing sheet is located between the positioning boss 3 and the positioning block 2. When gluing the specimen main board 10 and the reinforcing sheet, first place the reinforcing sheet between the positioning block 2 and the positioning boss 3. Since the positioning boss 3 has a profile structure corresponding to the reinforcing sheet, that is, the profile of the positioning boss 3 has a positioning effect on the reinforcing sheet, and then the positioning block 2 is used to abut against the other end of the reinforcing sheet, so that the reinforcing sheet is limited. Then, the adhesive film is pasted on the reinforcing sheet, and the specimen main board 10 is placed on it to complete the accurate bonding of the specimen main board 10 and the reinforcing sheet; at least two positioning blocks 2 are respectively located on both sides of the positioning boss 3, and reinforcing sheets can be placed on both sides of the positioning boss 3 at the same time to complete the bonding at both ends of the specimen main board 10; the limited area of ​​the limit block can also limit the specimen main board 10, and further, the reinforcing sheet can continue to be bonded above the specimen main board 10, and the positioning is completed by only abutting against the positioning block 2.

[0030] like Figure 3 and Figure 5 As shown, the end of the reinforcing sheet is provided with a first inclined surface 4, and the profile is a second inclined surface 5 corresponding to the first inclined surface 4. The first inclined surface 4 and the second inclined surface 5 correspond to each other and can be spliced ​​into a rectangular shape. The structure and principle are simple, and the positioning of the reinforcing sheet below the specimen main board 10 is quickly completed. The second inclined surface 5 extends outward from the positioning boss body 12, and the height gradually decreases. The first inclined surface 4 and the second inclined surface 5 are arranged oppositely. After the two are spliced ​​together, a rectangular structure is formed, and the positioning is quickly completed. A limiting step 6 is set between the second inclined surface 5 and the positioning boss body 12, and the edge of the first inclined surface 4 abuts on the limiting step 6. In order to prevent the first inclined surface 4 from sliding, dislocation and other problems again after being spliced ​​on the second inclined surface 5, the limiting step 6 is set to limit the sliding problem of the first inclined surface 4 along the second inclined surface 5. The other end of the reinforcing sheet is limited by the positioning block 2, and the reinforcing sheet is fixed and will not slide or dislocate.

[0031] Preferably, the height of the first bevel 4 is not greater than the height of the second bevel 5. For example, if the height of the second bevel 5 is 6 mm, the height of the first bevel 4 is 4-6 mm. This arrangement is due to the use of CNC molding for the bevel and end of the reinforcement plate, and the machining tolerance is ±1 mm, and the tolerance of the bonding tooling mold is different, otherwise there will be interference, and the lower end reinforcement plate will not fit into the slot and will get stuck.

[0032] Preferably, a pressure plate 7 is further included, wherein the reinforcing sheet includes an upper reinforcing sheet 8 and a lower reinforcing sheet 9, wherein the lower reinforcing sheet 9 is located below the end of the specimen main board 10 and is limited between the positioning boss 3 and the positioning block 2, and the upper reinforcing sheet 8 is located above the end of the specimen main board 10, and the pressure plate 7 is pressed above the upper reinforcing sheet 8. Specifically, the lower reinforcing sheet 9 is limited by the positioning block 2 and the limiting step 6 and will not move; while the upper reinforcing sheet 8 fixed above the end of the specimen main board 10 may move during the curing process, and after the pressure plate 7 is added above the upper reinforcing sheet 8, the problem of slippage will not occur due to the pressure of the pressure plate 7. After the adhesive film is applied between the reinforcing sheet and the specimen main board 10 and they are bonded to each other, a release agent is applied to the pressure plate 7 and pressed above the upper reinforcing sheet 8, and finally, vacuum compaction is performed by bag making, and the pressure plate 7 is removed to obtain a reinforcing sheet bonded to both the upper and lower ends of the specimen main board 10 after curing.

[0033] Preferably, the height of the limit block is greater than the height of the pressure plate 7, that is, the pressure plate 7 is also within the limiting area enclosed by the limit block, which not only plays a limiting role on the pressure plate 7, but also further ensures that the pressure plate 7 will not move and the upper reinforcing plate 8 pressed by the pressure plate 7 will not slip.

[0034] Preferably, the positioning block 2 is a detachable structure. For example, there is a first mounting hole on the positioning block 2, and the base plate 1 has a second mounting hole corresponding to the first mounting hole, and there are multiple second mounting holes. When the position of the positioning block 2 needs to be adjusted, it is only necessary to match the first mounting hole to the appropriate second mounting hole and then insert the bolt.

[0035] Preferably, a lifting ring 11 is installed on the base plate 1 to facilitate the suspension and movement of the bonding tool.

[0036] Working principle: When gluing, first place the lower reinforcing sheet 9 on the bottom plate 1, and position it by the cooperation of the first inclined surface 4 and the second inclined surface 5, and limit it by using the limiting step 6 and the positioning block 2, and then spread the adhesive film on the lower reinforcing sheet 9, and then place the specimen main board 10 on the lower reinforcing sheet 9 for bonding; the adhesive film is also spread on the upper reinforcing sheet 8, and the positioning is completed after it abuts against the positioning block 2. After bonding to the specimen main board 10, press the upper reinforcing sheet 8 with the pressing plate 7 to prevent the upper reinforcing sheet 8 from sliding, and coat the pressing plate 7 with a release agent to prevent bonding. Finally, the whole bag is made and vacuumed to complete the curing.
