Description

A sample preparation aid for the screw holding force of artificial board Technical Field

[0001] This utility model relates to the field of artificial board testing technology, specifically to an auxiliary device for preparing samples of screw holding force of artificial boards. Background Technology

[0002] Screw holding force of engineered wood products is one of the important indicators for measuring the quality of engineered wood products. When testing the screw holding force of engineered wood products, it is necessary to cut the engineered wood products into 75mm×50mm samples, drill a guide hole at the center point of the sample surface, and then screw in a self-tapping screw for testing. At present, the preparation of engineered wood product screw holding force samples mainly relies on manual operation. The manual operation is cumbersome and inefficient. In addition, manual operation is prone to problems such as inaccurate guide hole position and inconsistent screw insertion depth, which affects the quality of the sample. Therefore, an auxiliary device for preparing engineered wood product screw holding force samples was designed. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary device for making screw-holding force samples of artificial boards, in order to solve the problem mentioned in the background art that the making of screw-holding force samples of artificial boards mainly relies on manual operation, which is cumbersome, inefficient, and prone to problems such as inaccurate guide hole positions and inconsistent screw insertion depths, thus affecting the quality of the samples.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for making samples of screw holding force on artificial boards, comprising a base, a stud fixedly connected to the surface of the base, a bolt threadedly connected to the surface of the stud, a positioning plate perforated and connected to the surface of the bolt, a slot formed on the surface of the base, a guide mechanism provided on the surface of the positioning plate, the guide mechanism comprising an internal threaded ring fixedly connected to the surface of the positioning plate, a guide sleeve threadedly connected to the surface of the internal threaded ring, an external thread provided on the surface of the guide sleeve, a positioning ring fixedly connected to the surface of the guide sleeve, a depth limiter threadedly connected to the bottom of the guide sleeve, and a limit ring fixedly connected to the inner surface of the depth limiter.

[0005] Preferably, a circular hole is formed on the surface of the positioning plate, and the bolt passes through the circular hole on the surface of the positioning plate and is threadedly connected to the stud, thereby restricting the positioning plate to the surface of the stud.

[0006] Preferably, four sets of bolts are provided, and the positioning plate is located directly above the slot.

[0007] Preferably, a guide hole is formed on the surface of the positioning plate, the center of the internal threaded ring and the center of the guide hole of the positioning plate are located on the same vertical line, and the internal threaded ring is located directly above the guide hole of the positioning plate.

[0008] Preferably, the external threads are provided in two sets, located at the top and bottom of the guide sleeve respectively. The guide sleeve is connected by an internal thread ring thread at the top and by an external thread and a depth limiter thread at the bottom.

[0009] Preferably, the top of the guide sleeve is threaded through the guide hole of the positioning plate and the internal threaded ring, and the guide sleeve restricts the position of the guide sleeve on the guide hole of the positioning plate by the positioning ring.

[0010] Preferably, the inner diameter of the limiting ring is smaller than the inner diameter of the guide sleeve, the limiting ring is installed directly below the guide sleeve by a depth limiter, and the centers of the limiting ring and the guide sleeve are on the same vertical line.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This auxiliary device inserts a guide sleeve through the guide hole of the positioning plate, connecting the external thread and the internal thread ring at the top of the guide sleeve. A depth limiter is then threaded onto the external thread at the bottom of the guide sleeve. The depth limiter drives the limit ring to be installed at the bottom of the guide sleeve. A self-tapping screw passes through the internal thread ring and the guide hole of the positioning plate, entering the guide sleeve. Inside the guide sleeve, the self-tapping screw is screwed into the wooden board, with the tail of the screw contacting the limit ring. This guiding mechanism can quickly and accurately screw the self-tapping screw into the appropriate position and depth, ensuring sample quality while being simple, convenient, and efficient.

[0013] 2. This auxiliary device allows the depth limiter to be rotated on the external thread at the bottom of the guide sleeve, which changes the height of the depth limiter at the bottom of the guide sleeve, and thus changes the height of the limit ring at the bottom of the guide sleeve. By changing the height of the limit ring, the depth to which the self-tapping screw is screwed into the wooden board can be changed, thereby improving the adaptability of the auxiliary device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5, which show one embodiment of this utility model:

[0022] A sample preparation aid for the screw holding force of a synthetic board includes a base 1, a stud 11 fixedly connected to the surface of the base 1, a bolt 12 threadedly connected to the surface of the stud 11, a positioning plate 13 perforated and connected to the surface of the bolt 12, a slot 14 formed on the surface of the base 1, and a guide mechanism provided on the surface of the positioning plate 13. The guide mechanism includes an internal threaded ring 2, which is fixedly connected to the surface of the positioning plate 13. A guide sleeve 21 is threadedly connected to the surface of the internal threaded ring 2, and an external thread 22 is provided on the surface of the guide sleeve 21. A positioning ring 23 is fixedly connected to the surface of the guide sleeve 21, and a depth limiter 24 is threadedly connected to the bottom of the guide sleeve 21. A limit ring 25 is fixedly connected to the inner surface of the depth limiter 24. The artificial board will be snapped into the slot 14. A drill guide hole is opened on the artificial board. The positioning plate 13 uses a guide mechanism to detect the self-tapping screws being screwed into the drill guide hole of the artificial board. Under the guidance of the guide mechanism, the self-tapping screws can be screwed into the appropriate position and depth quickly and accurately, ensuring the quality of the sample while being simple, convenient and efficient.

[0023] Furthermore, a circular hole is provided on the surface of the positioning plate 13. The bolt 12 passes through the circular hole on the surface of the positioning plate 13 and is threadedly connected to the stud 11. The bolt 12 restricts the positioning plate 13 on the surface of the stud 11, thereby completing the installation of the positioning plate 13 on the base 1. The positioning plate 13 and the base 1 are parallel to each other on the stud 11.

[0024] Furthermore, four sets of bolts 12 are provided to ensure the stability of the support for the positioning plate 13. The positioning plate 13 is located directly above the slot 14. The guide mechanism on the positioning plate 13 is directly opposite the wooden board on the slot 14, and the size of the wooden board is adapted to the size of the slot 14 to prevent the wooden board from moving on the slot 14.

[0025] Furthermore, a guide hole is provided on the surface of the positioning plate 13, and the center of the guide hole of the internal thread ring 2 and the positioning plate 13 is located on the same vertical line. The internal thread ring 2 is located directly above the guide hole of the positioning plate 13, and the guide hole of the positioning plate 13 and the drilled guide hole of the wooden board are located on the same vertical line, which facilitates the precise guidance of the self-tapping screw.

[0026] Furthermore, there are two sets of external threads 22, located at the top and bottom of the guide sleeve 21 respectively. The guide sleeve 21 is threadedly connected to the internal thread ring 2 at the top and to the depth limiter 24 at the bottom via the external thread 22. This facilitates the quick installation of the depth limiter 24 onto the guide sleeve 21 and also enables the quick installation of the guide sleeve 21 onto the positioning plate 13, ensuring the assembly efficiency of the guide mechanism on the positioning plate 13.

[0027] Furthermore, the top of the guide sleeve 21 is threaded through the guide hole of the positioning plate 13 and the internal threaded ring 2. The guide sleeve 21 restricts its position on the guide hole of the positioning plate 13 through the positioning ring 23. The positioning ring 23 will contact and connect to the bottom of the guide hole of the positioning plate 13, thereby making the guide sleeve 21 tightened on the internal threaded ring 2, ensuring that the installation position of the guide sleeve 21 on the positioning plate 13 is consistent each time, thus ensuring the guiding accuracy of the self-tapping screw.

[0028] Furthermore, the inner diameter of the limiting ring 25 is smaller than the inner diameter of the guide sleeve 21. The limiting ring 25 is installed directly below the guide sleeve 21 via the depth limiter 24, and the centers of the limiting ring 25 and the guide sleeve 21 are on the same vertical line. The guide sleeve 21 directly guides the self-tapping screw at the insertion position in the wooden board, while the limiting ring 25 inside the depth limiter 24 allows the tail of the self-tapping screw to contact and connect with the limiting ring 25, thereby limiting the self-tapping screw from continuing to descend and ensuring the screwing depth of the self-tapping screw.

[0029] Working principle: After drilling a guide hole in the wooden board, it is placed in the slot 14. The slot 14 restricts the position of the wooden board on the base 1. The bolt 12 is threaded through the circular hole of the positioning plate 13 and the stud 11, completing the positioning plate 13's positioning on the stud 11. A guide mechanism is installed on the positioning plate 13. The guide sleeve 21 is threaded through the guide hole of the positioning plate 13, and the external thread 22 at the top of the guide sleeve 21 is threadedly connected to the internal thread ring 2. Then, the depth limiter 24 is threadedly connected to the external thread 22 at the bottom of the guide sleeve 21. At this time, the depth limiter 24 drives the limiting ring 25 to be installed at the bottom of the guide sleeve 21. The self-tapping screw is threaded through the internal thread ring 2 and the guide hole of the positioning plate 13, and the self-tapping screw enters the guide sleeve 21. The self-tapping screw is screwed into the wooden board inside the guide sleeve 21, and the tail of the self-tapping screw contacts the limiting ring 25. This guide mechanism can quickly and accurately screw the self-tapping screw into the appropriate position and depth, ensuring sample quality while being simple, convenient, and efficient.

[0030] Rotating the depth limiter 24 on the external thread 22 at the bottom of the guide sleeve 21 can change the height of the depth limiter 24 at the bottom of the guide sleeve 21, thereby changing the height of the limit ring 25 at the bottom of the guide sleeve 21. By changing the height of the limit ring 25, the depth to which the self-tapping screw is screwed into the wooden board can be changed, thereby improving the adaptability of the auxiliary device.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
