Traditional fixtures and testing methods lack cutting guidance, automatic centering, and verticality calibration functions. They require manual marking or the use of a level to paste standard blocks. They lack positioning slots, which easily leads to misalignment between the standard blocks and the samples. This makes it impossible to accurately reflect the bonding strength of the tiles and results in large test deviations. Furthermore, they cannot adjust the centering according to different sample tiles and non-standard tiles, requiring the replacement of different fixtures and increasing equipment costs. Summary of the Invention

[0004] The main purpose of this utility model is to provide an auxiliary fixture for testing the bonding strength of facade tiles. It aims to eliminate the need for manual marking and centering adjustments, and to adjust the size of the marking marks and the centering and positioning of the standard block during pasting, thereby improving the efficiency of facade tile bonding strength testing and reducing testing errors.

The second rack is fixed to the first driving member.

[0014] In an alternative embodiment, the housing is provided with two stops, and the first drive member is installed between the two stops.

The marking assembly is dipped in ink. After aligning one side of the adjusting plate assembly with the original edge of the standard tile, the suction cups on both sides are pressed and fixed to the two sides of the tile to be tested. The moving assembly is driven to move up and down or left and right to adjust the standard brick so that the adjacent sides align with the original edges of the tile. The first driving component is then extended to attach the marking assembly to the tile, marking the area to be cut. The first driving component retracts and is then removed. This adhesive strength testing auxiliary fixture involves manually cutting a sample area from a marked area, aligning the fixture with the sample area, fixing it in place, applying adhesive to a standard brick, and then driving the first drive component to extend and press the standard brick against the sample area. After the adhesive dries, the first drive component retracts at a uniform speed, applying tension to the sample until it breaks. The test data is then recorded, completing the adhesive strength test of the tile. It can be seen that using a mechanical structure for marking the area to be cut, centering and positioning the standard block reduces reliance on manual operation, improves positioning accuracy and efficiency, and greatly eliminates human error.

[0024] In this embodiment of the invention, the adhesive strength testing auxiliary fixture specifically includes: a clamping mechanism 100, a housing 30, an adjusting mechanism 200, and two suction cups 31, which are respectively mounted on the housing 30. The two suction cups 31 can be vacuum suction cups 31, featuring a one-touch locking mechanism and threaded interface. Connecting rods are provided on both sides of the housing 30, and each connecting rod can be fitted with 2-3 small, retractable positioning pins for positioning the fixture in the same position when reinstalled.

When it reaches its maximum value, the limiting block 11b restricts the movement of the boss 12b, preventing excessive stretching of the first adjusting plate 11 and the second adjusting plate 12. Preferably, silicone rubber pads are installed on the contact surfaces of the first adjusting plate 11 and the second adjusting plate 12 with the standard brick 32 to protect the surface of the standard brick, increase friction, and prevent slippage, but this is not the only option.

Preferably, the middle plate 15 can be made of 45 steel, which has high strength, good rigidity, wear resistance and is not easily deformed, and has a high cost performance, but it is not limited to this.

[0029] Please refer to Figure 5 and Figure 8Each second telescopic assembly 18 includes a third rod 18a, a fourth rod 18b, and a spring 19. One end of the third rod 18a and one end of the fourth rod 18b are interlaced. The other ends of the third rod 18a and the fourth rod 18b are respectively fixed to the two first adjusting plates 11 or the two second adjusting plates 12 by interference fit. The spring 19 is installed between the third rod 18a and the fourth rod 18b. Understandably, the first rod 17a and the second rod 17b, or the third rod 18a and the fourth rod 18b, are in a nested sliding fit with grooves 13 and protrusions 15a. The grooves 13 of the first rod 17a and the protrusions 15a of the second rod 17b, or the grooves 13 of the third rod 18a and the protrusions 15a of the fourth rod 18b, have a guiding function. The corresponding ends of the first rod 17a and the second rod 17b, or the third rod 18a and the fourth rod 18b, respectively contact the two ends of the spring 19. After the standard brick 32 is placed in the first rod 17a and the second rod 17b, or the third rod 18a and the fourth rod 18b, the spring 19 is deformed by compression. After the standard brick 32 is removed, the spring 19 elastically returns to its original position, which can fit the two first adjusting plates 11 and the two second adjusting plates 12 into the centering plate 15. Preferably, the first rod 17a, the second rod 17b, the third rod 18a, and the fourth rod 18b can be made of 45 steel, which has high strength, is easy to process, and is suitable for heavy-duty telescopic movement, but is not limited to this.

[0031] Please refer to Figure 2The middle plate 15 is provided with a protrusion 15a, and both the protrusion 15a and the standard brick 32 are provided with locking grooves 33.

Preferably, the first driving member 20 can be a DC linear actuator motor, model JF-TG-5000, with thrust that meets the testing requirements, requiring no external power supply, and adopting a ball bearing 22c screw structure, which meets the requirement of uniform tensile force testing of the bonding strength testing auxiliary fixture, and is low in cost, but not limited to this. It can be understood that when the bonding strength testing auxiliary fixture does not lock the standard brick 32, the mounting block 20a installed on the first driving member 20 can lock the clamping mechanism 100. When the bonding strength testing auxiliary fixture locks the standard brick 32, the mounting block 20a can lock the clamping mechanism 100 and the standard brick 32 together.

[0032] Please refer to this again. Figure 5 and Figure 8 Each friction-reducing assembly 22 includes a first cover 22a, a second cover 22b, and a plurality of balls 22c. The first cover 22a is mounted on the second cover 22b. The first cover 22a and the second cover 22b are respectively provided with positioning grooves, and the plurality of balls 22c are respectively installed in the positioning grooves. It can be understood that the positioning grooves of the first cover 22a and the second cover 22b are respectively provided with retaining platforms. The positioning groove of the first cover 22a holds the plurality of balls 22c. The second cover 22b is closed with the first cover 22a and fixed to the outer casing 30 with screws. The retaining platforms of the first cover 22a and the second cover 22b secure the plurality of balls 22c and expose part of the plurality of balls 22c, thereby reducing the friction between the first driving member 20 and the moving assembly 21 by means of the balls 22c.

[0033] The moving assembly 21 includes a second driving member 21a, a main gear 21b, two first racks 21c, two second racks 21d, and a driven gear 21e. The second driving member 21a includes a driving part and an execution part connected to the driving part. The driving part drives the execution part to rotate. The driving part and the driven gear 21e of the second driving member 21a are respectively fixed to the housing 30 with screws. The main gear 21b is fixed to the execution part of the second driving member 21a with screws and meshes with the driven gear 21e. Each first rack 21c is in contact with several balls 22c and meshes with the driven gear 21e, and then meshes and locks with the corresponding second rack 21d. The second rack 21d is fixed to the first driving member 20 with screws. Preferably, the second driving member 21a can be a miniature DC geared motor. DC geared motors have a built-in reduction mechanism, sufficient torque, simple control, and small size, and are suitable for smooth operation of the adjustment mechanism 200, but are not limited to this. Preferably, the main gear 21b, the two first racks 21c, the second rack 21d, and the driven gear 21e can be made of quenched and tempered 45 steel, which has good machinability and wear resistance. Using the same material can reduce wear and extend service life, but it is not limited to this.

[0034] The housing 30 is provided with two stops 30a, and the first drive component 20 is installed between the two stops 30a. The housing 30 and the two stops 30a can be made of aluminum alloy, which has high strength, light weight, moderate cost and processing difficulty, is durable, ensures accuracy, and has strong load-bearing capacity, which can ensure the smooth operation of the clamping mechanism 100 and the adjusting mechanism 200, but is not limited to this.

[0035] Understandably, the first drive component 20 is equipped with a force sensor and a displacement sensor. The force sensor is connected in series with the first drive component 20 to measure the applied tension value in real time during the pulling process. A controller is installed on the housing 30, equipped with buttons and a display screen. The first drive component 20, the second drive component 21a, the force sensor, and the displacement sensor are electrically connected to the controller. The operator can set the extension and retraction parameters of the clamping mechanism 100 on the operation panel via the touch screen or buttons. The PLC sends a signal to the first drive component 20, causing the clamping mechanism 100 to extend or retract. A signal is also sent to the second drive component 21a, causing the main gear 21b to drive the driven gear 21e, which in turn drives the first drive component 20 to move. After moving the centering plate 15 to the target area, it waits for the next instruction. The operator can also view the working status and fault information in real time. The controller can optionally use a PLC, which can operate stably for a long time in the vibration, dust, and voltage fluctuation environment of the construction site.

[0036] In this utility model, the test batch and sampling are selected according to the "Standard for Testing the Bonding Strength of Facing Bricks in Building Engineering". A standard brick 32 with the same length and width as the sample to be tested is taken out. The standard brick 32 is attached to the centering plate 15 and fixed between the adjusting plate assembly 10. The marking group 16 is dipped in ink. After one side of the adjusting plate assembly 10 is parallel to the edge seam of the original side of the tile, the suction cups 31 on both sides are pressed and fixed to both sides of the test point of the tile. The moving group 21 is driven to move up and down or left and right to adjust so that the adjacent sides of the standard brick 32 are aligned with the edge seams of the original sides of the tile. The first driving member 20 is driven to extend and attach the marking group 16 to the tile, marking the area to be cut. The bonding strength testing auxiliary fixture is then removed after the first drive component 20 contracts and is manually cut out of the marked area. The bonding strength testing auxiliary fixture is then aligned with the sample area and fixed. Adhesive is applied to the standard brick 32, and the first drive component 20 is driven to extend and press the standard brick 32 against the sample area. After the adhesive dries, the first drive component 20 contracts again at a uniform speed to apply tension to the sample until the sample is damaged. The test data is recorded to complete the bonding strength test of the tile. It can be seen that the use of a mechanical structure for marking the area to be cut, centering and positioning the standard block reduces the dependence on manual operation, improves the positioning accuracy and efficiency, and greatly eliminates human error.
