DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1 —5. A foam core material shear test bonding positioning tooling comprises a core material 1, a first clamp 2 and a second clamp 3, and a positioning seat 4. The outer wall at the top of the positioning seat 4 is symmetrically provided with sliding grooves 41. Sliding rods 42 are symmetrically arranged in the positioning seat 4. The two ends of the sliding rods 42 are respectively slidably connected with the two sliding grooves 41. Abutment rods 43 are arranged on both ends of the sliding rods 42. A driving mechanism 5 is arranged in the positioning seat 4. The two sliding rods 42 are driven by the driving mechanism 5 to keep moving away from or towards each other, so that the abutment rods 43 and both sides of the core material 1 are aligned with the two sides of the first clamp 2 and the two sides of the second clamp 3 respectively.

[0024] The interior of the positioning seat 4 is a hollow structure, and sliding grooves 41 are symmetrically opened on the outer wall at the top of the positioning seat 4. Sliding rods 42 are symmetrically arranged inside the positioning seat 4. Specifically, the sliding rods 42 are "U"-shaped structures, and the two ends of the "U"-shaped structure of the sliding rod 42 are respectively slidably connected with the sliding grooves 41 on both sides of the positioning seat 4, and the two ends of the "U"-shaped structure of the sliding rod 42 respectively penetrate and extend to the outside of the sliding grooves 41, and abutment rods 43 are respectively fixedly installed at the two ends of the sliding rod 42 located outside the positioning seat 4. As an embodiment provided by the utility model, the abutment rod 43 is specifically an "L"-shaped structure, such as Figure 2 and Figure 3 As shown, the abutment rods 43 at both ends of the installed sliding rod 42 are arranged to face each other, so that when the sliding rod 42 keeps moving along the sliding groove 41, the abutment rod 43 with an "L"-shaped structure can keep in contact with the core material 1, thereby driving the core material 1 to keep moving laterally, and finally aligning the core material 1 with the side of the first clamp 2 or the second clamp 3. At the same time, due to the use of the abutment rod 43 with an "L"-shaped structure, the abutment rod 43 will not block the joint between the core material 1 and the first clamp 2 or the second clamp 3 during the movement, which can facilitate the operator to clean the glue overflowing from the joint between the core material 1 and the first clamp 2 or the second clamp 3.

[0025] The utility model drives the two sliding rods 42 to keep moving towards each other through the driving mechanism 5, and the abutment rods 43 set at both ends of the sliding rods 42 abut against the core material 1, thereby driving the core material 1 to move in the lateral direction of the first clamp 2 or the second clamp 3, thereby ensuring that the lateral direction of the core material 1 can be aligned with the lateral direction of the first clamp 2 or the second clamp 3, instead of manually aligning the core material 1 with the first clamp 2 and the second clamp 3, which can reduce the time for manual alignment of the core material 1, and at the same time can improve the assembly accuracy between the core material 1 and the first clamp 2 and the second clamp 3, and reduce the error in the shear performance test.

[0026] As an embodiment provided by the utility model, Figure 4 As shown, the driving mechanism 5 includes a rotating block 51, a first connecting rod 52 and a second connecting rod 53. The rotating block 51 is rotatably connected to the inner wall of one side of the hollow structure of the positioning seat 4 through a shaft, and a plug-in rod 44 is fixedly installed on the outer wall of the bottom of the "U"-shaped structure of the sliding rod 42, as shown in FIG. Figure 4As shown, one end of the first connecting rod 52 is rotatably connected to one end of the rotating block 51 through an axle, the other end of the first connecting rod 52 is rotatably connected to the plug-in rod 44 on one of the sliding rods 42, one end of the second connecting rod 53 is rotatably connected to one end of the rotating block 51 away from the first connecting rod 52 through an axle, the other end of the second connecting rod 53 is rotatably connected to the plug-in rod 44 on another sliding rod 42, by driving the rotating block 51 to keep rotating, the first connecting rod 52 and the second connecting rod 53 can be driven to keep rotating while the rotating block 51 keeps rotating, thereby driving the two sliding rods 42 to keep moving in the sliding groove 41, and finally driving the two sliding rods 42 to keep moving toward or away from each other.

[0027] As a further embodiment provided by the present utility model, the driving mechanism 5 further includes a first gear 54, a second gear 55 and a driving rod 56.

Specifically, the first gear 54 and the second gear 55 are both bevel gears. By driving the driving rod 56 to keep moving, the second gear 55 is driven to keep rotating, and the first gear 54 is further driven to keep rotating, so that the rotating block 51 can be driven to keep rotating, and finally the two sliding rods 42 are driven to keep moving toward or away from each other, which can be convenient for operators to use.

[0028] As a further embodiment provided by the present invention, Figure 3 and Figure 1 As shown, an abutment strip 45 is fixedly provided on the outer wall on the top side of the positioning seat 4. When in use, the abutment strip 45 can abut against the outer wall on one side of the first clamp 2 or the second clamp 3, which can facilitate the operator to quickly position the first clamp 2 and the second clamp 3.

[0029] As a further embodiment provided by the present invention, Figure 5 As shown, it also includes a mounting plate 6, on the outer wall of one side of the mounting plate 6, an abutment block 61 is fixedly installed, the number of the abutment blocks 61 is four, and the four abutment blocks 61 are distributed in a rectangular array on the outer wall of the mounting plate 6. The mounting plate 6 is fixedly installed inside the positioning seat 4, and the top of the abutment block 61 abuts against the outer wall of one side of the sliding rod 42. The abutment block 61 arranged on the mounting plate 6 can support the sliding rod 42 to ensure that the sliding rod 42 can maintain smooth sliding when sliding.
