For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0048] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0049] This embodiment provides a bonding positioning device, which can be used to position the reinforcement when bonding the reinforcement on the upper and lower sides of the workpiece to be bonded, thereby facilitating subsequent mechanical property tests such as stretching, bending, shearing, and torsion of the workpiece to be bonded. Among them, the shape of the workpiece to be bonded can be rectangular, L-shaped, T-shaped, C-shaped, etc.

[0050] As Figures 1-2 shown, the bonding positioning device includes a mold body 1 and a limiting component 2. The mold body 1 includes a first connecting member 11, an upper template 12 and a lower template 13 which are spaced apart in the vertical direction. The workpiece to be bonded and the reinforcements on both sides of the workpiece to be bonded are located between the upper template 12 and the lower template 13. Thus, the first connecting member 11 can connect the upper template 12 and the lower template 13, so that the upper template 12 and the lower template 13 can press the reinforcements on both sides of the workpiece to be bonded in the vertical direction. Further, the two reinforcements can press the workpiece to be bonded in the vertical direction. Among them, a glue film is laid between the workpiece to be bonded and the reinforcement to achieve the bonding of the workpiece to be bonded and the reinforcement. Optionally, the workpiece to be bonded is made of a composite material, and the reinforcement is a reinforcing sheet.

[0051] As Figure 3 shown, a first boss 121 is provided on the lower surface of the upper template 12, and a second boss 131 is provided on the upper surface of the lower template 13. Both the first boss 121 and the second boss 131 are used to sleeved with the reinforcement. Further, after the upper template 12 and the lower template 13 press the reinforcements on both sides of the workpiece to be bonded in the vertical direction, the reinforcement is sleeved on the inner wall of the positioning holes of the first boss 12 and the second boss 131 without glue overflow. And during subsequent machining of the workpiece to be bonded, the workpiece to be bonded with the reinforcement can be directly sleeved on other mechanical equipment through the positioning holes of the reinforcement to complete the positioning. Among them, the first boss 121 and the second boss 131 are arranged opposite to each other in the vertical direction, which can ensure the concentricity of the positioning holes of the reinforcements on the upper and lower sides of the workpiece to be bonded, and can also improve the position accuracy of the workpiece to be bonded during machining. Optionally, the first connecting member 11 is a positioning pin, so that the staff can use the positioning pin to limit the installation positions of the upper template 12 and the lower template 13, and further ensure that the first boss 121 and the second boss 131 can be arranged opposite to each other in the vertical direction. Further optionally, the first boss 121 and the second boss 131 are exactly the same in size and shape.

[0052] The limiting components 2 are respectively arranged on the upper template 12 and the lower template 13, and are used to limit the fiber directions of the parts to be bonded and the reinforcement parts respectively, so as to improve the position accuracy when the reinforcement part bonds the part to be bonded, and to effectively test the test data when the fiber direction of the reinforcement part and the fiber direction of the part to be bonded form different angles during the test. Optionally, the angle range of the included angle formed by the fiber direction of the part to be bonded and the fiber direction of the reinforcement part is 0 to 90°, so as to further improve the integrity and reliability of the test data when the part to be bonded is subjected to mechanical property tests. Among them, a first groove 122 is formed by inward depression on the lower surface of the upper template 12, and a second groove 132 is formed by inward depression on the upper surface of the lower template 13. The limiting components 2 are respectively arranged in the first groove 122 and the second groove 132, so as to prevent the limiting components 2 from interfering with the upper template 12 and the lower template 13 respectively and affecting the use of the limiting components 2. Optionally, a plurality of limiting components 2 are provided, and the plurality of limiting components 2 are respectively arranged at intervals along the outer circumferences of the upper template 12 and the lower template 13, so as to meet different limiting requirements for the parts to be bonded and the reinforcement parts during positioning.

[0053] As Figure 4 shown, the limiting component 2 includes an abutting member 21, a positioning block 22, and a guiding member 23 arranged on the positioning block 22. And an abutting member 21 and a guiding member 13 are slidably arranged horizontally on the upper template 12, and an abutting member 21 and a guiding member 13 are also slidably arranged horizontally on the lower template 13. Specifically, a through hole communicating with the first groove 122 is horizontally formed on the side surface of the upper template 12, and a through hole communicating with the second groove 132 is horizontally formed on the side surface of the lower template 13. Thus, both the abutting member 21 and the guiding member 23 can pass through the through holes, realizing the horizontal movement of the abutting member 21 and the guiding member 23 arranged on the upper template 12, and the horizontal movement of the abutting member 21 and the guiding member 23 arranged on the lower template 13, and facilitating the staff to adjust the position of the positioning block 22. Optionally, the through hole through which the abutting member 21 passes is an internal thread hole, and the abutting member 21 is threadedly connected with the internal thread hole to facilitate the staff to adjust the position of the positioning block 22.

[0054] Further, one end of the abutting member 21 in the horizontal direction abuts against the positioning block 22, which is used to drive the positioning block 22 to move in the horizontal direction. Then, the positioning block 22 abuts against and limits the adhesive member to be bonded and the reinforcing member in the horizontal direction, so as to ensure that the fiber directions of the adhesive member to be bonded and the reinforcing member meet the test requirements. Among them, the size of the positioning block 22 can be adjusted according to requirements. Thus, the positioning block 22 can limit the adhesive member to be bonded alone; or limit the reinforcing member alone; or limit the adhesive member to be bonded and the reinforcing member at the same time. Specifically, the reinforcing member provided on the upper template 12 can be limited by the positioning block 22 on the upper template 12, and the reinforcing member provided on the lower template 13 can be limited by the positioning block 22 on the lower template 13. Moreover, the adhesive member to be bonded can be limited by the positioning block 22 with a larger vertical dimension on the upper template 12 and / or the lower template 13. Among them, if the maximum dimensions of the adhesive member to be bonded and the reinforcing member in the horizontal direction are the same, the adhesive member to be bonded and the reinforcing member can be limited simultaneously by the same positioning block 22. Optionally, both the first boss 121 and the second boss 131 are cylindrical blocks. Thus, when the reinforcing member is respectively sleeved on the first boss 121 and the second boss 131, the reinforcing member itself can be rotated arbitrarily in the horizontal direction to meet the requirements for the fiber direction of the reinforcing member. Of course, the first boss 121 and the second boss 131 can also be other special-shaped shapes, which are not specifically limited in this embodiment.

[0055] Optionally, the lower surface of the upper template 12 and the upper surface of the lower template 13 are both square, and the area of the lower surface of the upper template 12 is the same as the area of the upper surface of the lower template 13, which is convenient for the staff to manufacture the upper template 12 and the lower template 13. Moreover, any upper template 12 can be matched with any lower template 13, so that the upper template 12 and the lower template 13 can be used in a cross-matching manner, improving the use efficiency of each upper template 12 and each lower template 13. At the same time, it can be avoided that when one of the upper template 12 or the lower template 13 is damaged, the entire adhesive positioning device is scrapped, resulting in an increase in cost. Among them, the first boss 121 is arranged at the middle position of the upper template 12, and the second boss 131 is arranged at the middle position of the lower template 13. Thus, when the reinforcing member is respectively sleeved on the upper template 12 and the lower template 13, the upper template 12 and the lower template 13 can cover the reinforcing member. And after adjusting the fiber angle of the reinforcing member, it is convenient for the limiting assembly 2 to limit the reinforcing member, avoiding the situation where the fiber angle of the reinforcing member cannot be adjusted when the first boss 121 is arranged at the edge position of the upper template 12 and the second boss 131 is arranged at the edge position of the lower template 13. Of course, the sizes of the upper template 12 and the lower template 13 can be adjusted according to the sizes of the adhesive member to be bonded and the reinforcing sheet, which are not specifically limited in this embodiment.

[0056] Further, the bonding positioning device further includes a second connecting member 3. The first boss 121 and the upper template 12 are detachably connected by the second connecting member 3, and the second boss 131 and the lower template 13 are also detachably connected by the second connecting member 3. Thus, it is convenient for the staff to replace the first boss 121 and the second boss 131 respectively to meet the requirements for different styles of reinforcing sheets. Optionally, the second connecting member 3 is a bolt structure. The bolt-structured second connecting member 3 is simple and convenient to disassemble, which can improve the work efficiency of the staff. Further optionally, the first boss 121 and the upper template 12 can be positioned by a positioning pin, and the second boss 131 and the lower template 13 can also be positioned by a positioning pin, so as to facilitate the direct connection of the second connecting member 3 between the first boss 121 and the upper template 12 and between the second boss 131 and the lower template 13.

[0057] This embodiment provides a method for using a bonding positioning device. The method for using the bonding positioning device is completed by using the bonding positioning device as described above. After positioning the reinforcing member 5 on the workpiece to be bonded 4, the workpiece to be bonded 4 with the reinforcing member 5 is then positioned on other mechanical equipment, such as Figure 5 As shown, the method for using the bonding positioning device includes the following steps:

[0058] S1. Install the workpiece to be bonded 4 and the reinforcing member 5 on the bonding positioning device, and adjust the limiting component 2 to adjust the fiber directions of the workpiece to be bonded 4 and the reinforcing member 5.

[0059] S2. Remove the connection between the upper template 12 and the lower template 13, and package and bag-cure the workpiece to be bonded 4 with the first boss 121 and the reinforcing member 5.

[0060] S3. After the workpiece to be bonded 4 and the reinforcing member 5 are bonded and cured, remove the bag, and remove the first boss 121 on the workpiece to be bonded 4. By flipping the workpiece to be bonded 4, the reinforcing member 5 can be sleeved on the second boss 131 on the lower template 13 of the mechanical equipment.

[0061] S4. Use the mechanical equipment to perform machining on the workpiece to be bonded 4.

[0062] The method for using the bonding positioning device provided in this embodiment is simple and convenient in use operation, and the positioning of the reinforcing member 5 on the workpiece to be bonded 4 is accurate. The limiting component 2 can effectively limit the fiber directions of the workpiece to be bonded 4 and the reinforcing member 5 respectively, thus facilitating the mechanical equipment to perform machining on the workpiece to be bonded 4 and testing the mechanical properties of the workpiece to be bonded 4. Optionally, the workpiece to be bonded 4 is a square flat plate made of carbon fiber composite material, and the reinforcing member 5 is a cross-shaped reinforcing sheet with a round hole.

[0063] As Figure 6 shown, in step S1, it includes:

[0064] S11. Sheath the reinforcing members 5 on the first boss 121 of the upper template 12 and the second boss 131 of the lower template 13 respectively, and adjust the limiting assembly 2 to adjust the fiber direction of the reinforcing members 5;

[0065] S12. Place the parts to be bonded 4 on the reinforcing members 5 on the lower template 13, and adjust the limiting assembly 2 to adjust the fiber direction of the parts to be bonded 4;

[0066] S13. Fasten the upper template 12 with the reinforcing members 5 on the lower template 13, and use the first connecting member 11 to position the position between the upper template 12 and the lower template 13 so that the parts to be bonded 4 and the reinforcing members 5 can be bonded.

[0067] Through steps S11, S12, and S13, it can be ensured that the reinforcing members 5 can be accurately positioned and bonded to the parts to be bonded 4, and this process can make the fiber direction of the parts to be bonded 4 and the fiber direction of the reinforcing members 5 meet the requirements of the staff, so as to facilitate the mechanical property test of the parts to be bonded 4; among them, when the reinforcing members 5 are sheathed on the inner walls of the positioning holes of the first boss 121 and the second boss 131, there will be no glue overflow, so as to reduce the error in the mechanical property test of the parts to be bonded 4.

[0068] As Figure 7 shown, in step S2, it includes:

[0069] S21. Remove the upper template 12 by disassembling the first connecting member 11, and remove the connection between the upper template 12 and the first boss 121 so that the first boss 121 remains above the parts to be bonded 4;

[0070] S22. Remove the parts to be bonded 4 with the first boss 121 and the reinforcing members 5 from the lower template 13, and fix the periphery of the parts to be bonded 4 with a release cloth to prevent the reinforcing members 5 from slipping;

[0071] S23. Package and bag the parts to be bonded 4 with the first boss 121 and the reinforcing members 5 for curing.

[0072] In step S21, by disassembling the first connecting member 11 and the second connecting member 3, the upper template 12 can be removed from the lower template 13, and the first boss 121 on the upper template 12 can also remain on the workpiece to be bonded 4. Furthermore, when the reinforcing member 5 is sleeved on the inner wall of the positioning hole of the first boss 121, there will be no glue overflow during curing; after curing is completed and the first boss 121 is disassembled, the positioning hole of the reinforcing plate can be sleeved on any other boss having the same shape as the disassembled first boss 121, thus facilitating the subsequent machining of the workpiece to be bonded 4 by mechanical equipment. Among them, using a release cloth can effectively prevent the reinforcing member 5 from slipping on the workpiece to be bonded 4, prevent the reinforcing members 5 bonded to the upper and lower sides of the workpiece to be bonded 4 from falling off, and prevent positioning errors of the reinforcing members 5 bonded to the upper and lower sides of the workpiece to be bonded 4.

[0073] As Figure 8 shown, in step S3, it includes:

[0074] S31. After the workpiece to be bonded 4 and the reinforcing member 5 are bonded and cured, the bag is opened, and the first boss 121 on the workpiece to be bonded 4 is removed;

[0075] S32. Clamp and position the lower template 13 on the mechanical equipment, and use the second boss 131 on the lower template 13 as a reference to perform tool setting on the mechanical equipment;

[0076] S33. Turn the workpiece to be bonded 4 with the reinforcing member 5 upside down, use the second boss 131 on the lower template 13 and the limiting component 2 for positioning, and place the workpiece to be bonded 4 with the reinforcing member 5 on the lower template 13 so that the reinforcing member 5 can be sleeved on the second boss 131;

[0077] S34. Use a pressing plate to fix the workpiece to be bonded 4 with the reinforcing member 5 on the lower template.

[0078] Among them, the removed first boss 121 can be reinstalled on the upper template 12 and used in cross - matching with other lower templates 13 to improve the usage efficiency of the bonding positioning device and avoid the phenomenon that a large number of upper templates 12 are in a state of waiting to be used. Clamping the lower template 13 on the mechanical equipment enables the workpiece to be bonded 4 with the reinforcing member 5 to be directly placed on the lower template 13, reducing the time cost and equipment cost generated when additional positioning devices are required for positioning during the machining of the workpiece to be bonded 4 by mechanical equipment; and the operator can perform tool setting on the mechanical equipment through the second boss 131 on the lower template 13, further enhancing the accuracy during the machining of the workpiece to be bonded 4.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
