Description

Technical Field

[0001] This invention relates to the field of power equipment, and in particular to a tool testing device. Background Technology

[0002] In electrical work, such as installing parts inside distribution cabinets or connecting wires, many tools are used, such as wrenches, screwdrivers, and pliers. The wear or deformation of these tools can significantly affect the efficiency of electrical work. Taking screwdrivers and pliers as examples, if the tip of a screwdriver is deformed or damaged, it will be unable to tighten screws accurately, causing slippage and affecting normal use. Similarly, if the threads on the tip of pliers are worn, deformed, or even damaged, the pliers will not be able to grip or hold wires, terminals, or other components, significantly increasing the difficulty of the work.

[0003] Existing testing devices, such as the previous patent with application number 202022703681.1, provide a quality testing device for electric screwdriver bits. This device detects the condition of the bit tip by looking at the mark left by the tip on the inkpad. However, since the mark on the inkpad has depth, different viewing angles and lighting conditions can affect the test results, increasing the difficulty of testing and slowing down the testing speed.

[0004] Based on the above, there is an urgent need for a tool and equipment testing device that can quickly and accurately detect the wear or deformation of tools and equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a tool and equipment detection device that can quickly and accurately detect the wear or deformation of tools and equipment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Tool and equipment testing device, including:

[0008] The imprint tape has its two ends stretched by a first preset tension, and one side surface of the imprint tape is configured as an ink-printing surface.

[0009] The elastic band has its two ends stretched by a second preset tension. One side surface of the elastic band is configured as an ink-bearing surface, which is provided with an ink layer. The elastic band is arranged at preset distances from the imprinting band, with the ink-bearing surface parallel to and facing the imprinting surface. The other side surface of the elastic band is configured as an abutting surface, which is arranged opposite to the ink-bearing surface. The tool to be tested can abut against the abutting surface and deform the ink-bearing surface. The deformed ink-bearing surface can abut against the imprinting surface and form an ink mark on the imprinting surface corresponding to the deformed ink-bearing surface.

[0010] Optionally, the ink-printing surface is provided with paper, the ink-bearing surface is provided with carbon paper, the carbon paper is provided with an ink layer, and the ink marks are formed on the paper.

[0011] Optionally, the above-mentioned tool testing device also includes an ink cartridge, which is used to coat the ink-covered surface with ink or toner.

[0012] Optionally, the above-mentioned tool testing device further includes a heating component for heating the ink printing surface.

[0013] Optionally, the above-mentioned tool testing device further includes a mounting plate and two first rotating drums, the two first rotating drums being rotatably fixedly connected to the mounting plate, and the two ends of the marking strip being rotatably wound around the two first rotating drums respectively.

[0014] Optionally, the above-mentioned tool testing device further includes two second rotating drums, which are rotatably fixed to the mounting plate, and the two ends of the elastic band are respectively rotatably wound around the two second rotating drums.

[0015] Optionally, the above-mentioned tool and equipment testing device further includes a batch testing component, which is disposed on one side of the contact surface. The batch testing component includes a tray, on which a plurality of tool and equipment fixing structures are disposed.

[0016] Optionally, the above-mentioned tool fixing structure includes a screwdriver fixing structure, which includes a clamping plate capable of holding and fixing the screwdriver.

[0017] Optionally, the above-mentioned tool fixing structure includes a pliers fixing structure, which includes a stop block and two limiting plates. The two limiting plates are arranged in a figure-eight shape. The stop block is installed between the two limiting plates. The pliers to be fixed can be fixed in an open state between the stop block and the two limiting plates, and the end of the pliers extends out of the top opening of the figure-eight shape.

[0018] Optionally, the batch inspection component further includes a drive structure. After the tool fixing structure fixes the tool, the drive structure can drive the tool to move toward the contact surface.

[0019] The beneficial effects of the tool and implement testing device provided by this invention are as follows: By setting an imprinting strip with an ink-receiving surface and an elastic strip with an ink-receiving surface, the tool and implement to be tested can abut against the elastic strip, causing the ink-receiving surface to deform. Then, the ink-receiving surface abuts against the imprinting surface, forming an ink mark corresponding to the deformation on the imprinting surface. This results in a planar ink mark that is easy to observe after unfolding, enabling rapid and accurate qualitative judgment, greatly reducing testing time and labor costs. Simultaneously, ink or toner will not adhere to the surface of the tool and implement, preventing contamination and increased cleaning costs. Attached Figure Description

[0032] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The following is based on Figures 1 to 10 The present invention provides a tool testing device through two embodiments.

[0036] Example 1

[0037] Reference Figure 1 As shown, the tool testing device provided by the present invention includes a mounting plate 2, a first rotating drum 5, an imprinting belt 13, a second rotating drum 11, and an elastic belt 9.

[0038] The elastic band 9 is made of a deformable elastic material and is set with the imprinted bands 13 at preset intervals. One side of the elastic band 9 is an ink-bearing surface with an ink layer, and the opposite side is an abutting surface. The tool to be tested can abut against the abutting surface, forcing the ink-bearing surface to deform. For example, the elastic band 9 is made of rubber, and its thickness (i.e., the distance between the ink-bearing surface and the abutting surface) corresponds to the specifications of the tool to be tested. For example, when the small pliers to be tested have denser teeth, a thinner elastic band 9 is used so that the deformation of the ink-bearing surface can reflect the approximate shape of the teeth; while when the large pliers to be tested have sparser teeth, the thickness of the elastic band 9 can be appropriately increased. Of course, the magnitude of the second preset tension is also related to the deformation amount. Therefore, in this invention, the material, thickness, and magnitude of the second preset tension of the elastic band 9 are not specifically limited, as long as the deformation of the ink-bearing surface after abutment can qualitatively reflect the approximate shape of the teeth.

[0039] Continue to refer to Figure 1 , Figure 2 As shown, two first rotating cylinders 5 and two second rotating cylinders 11 are mounted on the mounting plate 2. The two ends of the marking tape 13 are respectively wound around and fixed to the two first rotating cylinders 5, allowing the two ends of the marking tape 13 to be tightened with a first preset tension. The two ends of the elastic band 9 are respectively wound around and fixed to the two second rotating cylinders 11, allowing the two ends of the elastic band 9 to be tightened with a second preset tension. One side surface of the marking tape 13 is the ink-printing surface, facing the ink-bearing surface. When the tool abuts against the contact surface and causes the ink-bearing surface to deform, the ink-bearing surface can abut against the ink-printing surface, forming an ink mark on the ink-printing surface corresponding to the aforementioned deformation.

[0040] It should be noted that the imprint tape 13 can be made of either an elastic or non-elastic material, as long as it can be tensioned under a first preset tension to facilitate contact between the ink-carrying surface and the printing surface. Of course, this invention does not impose specific limitations on the thickness of the imprint tape 13, the preset distance between the elastic band 9 and the imprint tape 13, etc., as long as the ink-carrying surface deforms and contacts the printing surface, leaving an ink mark corresponding to the deformation. For example, in this invention, the imprint tape 13 is also made of rubber with a thickness of 0.8-1cm, possessing a certain degree of deformation capability. The preset distance between the elastic band 9 and the imprint tape 13 is 1.5-3cm, which can accurately produce an ink mark corresponding to the deformation of the elastic band 9 during detection.

[0041] In use, for example, taking a flathead screwdriver, the ink marks produced by a perfectly good flathead screwdriver when in contact with the object are as follows: Figure 4 As shown, only complete ink marks 29 are present, while when a flathead screwdriver is partially damaged, it will form as shown in the image. Figure 5The incomplete ink mark 28 shown; taking a Phillips screwdriver as an example, the ink mark produced by a good Phillips screwdriver when in contact is as follows. Figure 6 As shown, only complete ink marks 29 are present, while when the Phillips screwdriver is partially damaged, marks like... Figure 7 The incomplete ink mark 28 shown; taking pliers as an example, the complete ink mark 29 produced by the contact of the intact pliers ends is as follows. Figure 8 As shown, when the teeth of the pliers are damaged, it will form a shape like... Figure 9 The incomplete ink mark shown is 28.

[0042] By setting up an imprinting band 13 with an ink-coated surface and an elastic band 9 with an ink-coated surface, the tool to be tested can come into contact with the elastic band 9, causing the ink-coated surface to deform. Then, the ink-coated surface comes into contact with the ink-coated surface, forming an ink mark corresponding to the deformation. By qualitatively judging the ink mark, it is possible to quickly, conveniently, and accurately determine whether the tool is deformed or worn. In particular, the ends or textures of tools are prone to rust or dirt after long-term use, making visual inspection difficult, slow, and inaccurate. However, the tool inspection device described above can obtain easily observable planar ink marks after unfolding, enabling rapid and accurate qualitative judgment, greatly reducing inspection time and labor costs. At the same time, ink or toner will not adhere to the tool surface, preventing contamination and increased cleaning costs.

[0043] Optionally, the first rotating drum 5 and the second rotating drum 11 are rotatably fixed to the mounting plate 2, allowing the marking tape 13 and the elastic tape 9 to rotatably wrap around the first rotating drum 5 and the second rotating drum 11. This increases the length of the marking tape 13 and the elastic tape 9 in the tool detection device, significantly increasing the number of tools that the tool detection device can detect without increasing the size of the tool detection device. Exemplarily, in this embodiment, the mounting plate 2 is equipped with a second rotating shaft 12, and the second rotating drum 11 is rotatably fitted and fixed to the second rotating shaft 12. Of course, in some other embodiments, connectors, snap-fit ​​devices, etc., can also be used to rotatably mount the first rotating drum 5 and the second rotating drum 11 to the mounting plate 2; this invention does not specifically limit this method.

[0044] It is understandable that by using the above-mentioned method of installing the marking tape 13 and the elastic tape 9, the first preset tension and the second preset tension can be adjusted to solve the problem that it is not easy to form clear ink marks when testing different tools due to the specifications, shapes and other reasons of the tools. This satisfies the testing requirements of different tools and makes the tool testing device have good compatibility.

[0045] Furthermore, such as Figure 1As shown, the mounting plate 2 is mounted on the support frame 7 via the connecting rod 8, and the support member is fixedly mounted on the support plate 6. Sufficient mounting space is formed between the upper side of the support plate 6 and the lower side of the mounting plate 2. A first motor 3 is installed in the mounting space, and the output end of the first motor 3 passes through the mounting plate 2. A first rotating drum 5 is located on the upper side of the mounting plate 2 and is drivenly connected to the output end of the first motor 3. By controlling the rotation and stopping of the first motor 3, the marking tape 13 can be rotated relatively easily, and the magnitude of the first preset tension can be controlled more easily. Exemplarily, in this embodiment, the mounting plate 2 is equipped with a first rotating shaft 4, and the first rotating drum 5 is sleeved on the first rotating shaft 4. The first rotating shaft 4 is connected to the output end of the first motor 3. Of course, in some other embodiments, a second rotating drum 11 can also be drivenly connected to the output end of the motor to control the magnitude of the second preset tension.

[0046] Optionally, in this embodiment, as Figure 2 , Figure 10 As shown, the tool and equipment testing device also includes an ink cartridge 10, which contains ink or toner. This ink or toner can coat the ink-bearing surface, preventing the ink-bearing surface from failing to produce clear ink marks when in contact with the printing surface due to dry or insufficient ink. Exemplarily, in this embodiment, the ink cartridge 10 is mounted on the mounting plate 2, and an elastic band 9 passes through the ink cartridge 10. When the operator rotates the second rotating drum 11, the elastic band 9 moves and passes through the ink cartridge 10, forming a wet ink layer or a sufficient ink layer on the ink-bearing surface of the elastic band 9, which is more conducive to forming clear ink marks on the printing surface.

[0047] Optionally, such as Figure 2 As shown, in this embodiment, the tool detection device further includes a heating component 1. This heating component 1 can heat the ink-printing surface, which is beneficial for drying the ink marks on the ink-printing surface after the ink-bearing surface and the ink-printing surface come into contact and separate. This prevents the ink marks from becoming unclear due to ink splattering, thus affecting the accuracy of the qualitative judgment of the ink marks. The heating component 1 can be a heating lamp or a heating fan; this invention does not specifically limit it, as long as it can heat the ink-printing surface during or after contact.

[0048] Example 2

[0049] Based on Embodiment 1, this embodiment sets up a batch detection component based on the principle of ink stain detection. The batch detection component is set on one side of the contact surface. The batch detection component includes a tray 14, on which a plurality of tool fixing structures are provided. The plurality of tool fixing structures can conveniently fix tools in batches, avoiding the operator from repeatedly picking up and putting down the tools to be tested, and facilitating the operator to conduct batch testing of tools.

[0050] Specifically, such as Figure 2 , Figure 3As shown, the tool fixing structure includes a pliers fixing structure and a screwdriver fixing structure. The pliers fixing structure includes a stop block 24 and two limiting plates 15. The two limiting plates 15 are arranged in a "V" shape, with the stop block 24 installed within the "V" shape. The pliers to be fixed can be fixed in an open state between the stop block 24 and the limiting plates 15, and the end of the pliers extends out of the top opening of the "V" shape. In use, the operator only needs to push the gripping end of the pliers, and the pliers can move towards the contact surface. When moving to the point where the ink-bearing surface deforms and contacts the ink surface, it still maintains a certain opening angle, allowing the teeth at the end to indirectly leave relatively clear ink marks on the ink surface.

[0051] Continue to refer to Figure 2 As shown, the screwdriver fixing structure includes a clamping plate 27, which can hold and fix the screwdriver. Exemplarily, in this embodiment, the clamping plate 27 is U-shaped, and the screwdriver handle can be clamped and fixed within the U-shaped clamping plate 27. Optionally, a rubber friction layer 26 is further provided on the inner side of the U-shaped clamping plate 27, which can further increase the friction between the screwdriver and the clamping plate 27, preventing the screwdriver from falling out.

[0052] Of course, in some other embodiments, the screwdriver can also be clamped by two fixing plates (not shown in the figure), with an elastic element between the two fixing plates. The elastic force causes the two fixing plates to abut against both sides of the screwdriver handle, forming a clamping force. Therefore, in this invention, the structure of the clamping plate 27 is not specifically limited, as long as it can clamp and fix the screwdriver.

[0053] Furthermore, the batch inspection component also includes a drive structure. After the tool fixing structure fixes the tool, the drive structure can drive the tool to move toward the contact surface, causing the elastic band 9 to deform and abut against the marking band 13 to produce a clearer ink mark.

[0054] Optionally, in some embodiments, the drive structure includes a push rod motor (not shown in the figure), which is fixedly mounted on the mounting plate 2. The aforementioned support plate 14 is slidably mounted on the mounting plate 2 and connected to the push rod of the push rod motor. Under the push of the push rod motor, the support plate 14 and several tools fixed on the support plate 14 can abut against the elastic band 9.

[0055] For example, in this embodiment, such as Figure 1 , Figure 2As shown, a second connecting rod 23 and a first connecting rod 17 are respectively installed on the side of the mounting plate 2. A second motor 18 is fixedly installed at the lower end of the first connecting rod 17, and a gear 19 is installed in the middle of the second motor 18. A slip ring 22 is fixedly installed at the lower end of the second connecting rod 23, and a slide frame 21 is fitted inside the slip ring 22. A rack 20 is welded to the right side of the slide frame 21. The gear 19 meshes with the rack 20, and the slide frame 21 slides with the slip ring 22. A push plate 16 is fixedly installed at the upper end of the slide frame 21. In use, the second motor 18 drives the push plate 16 to move towards the elastic band 9, and the push plate 16 can abut against tools such as screwdrivers and pliers, thereby pushing the tools against the elastic band 9.

[0056] Understandably, when using the aforementioned batch inspection components, the lengths of the screwdrivers, pliers (in their open state), and other tools being inspected should be similar. If the lengths differ too much, some tools may fail to form effective ink marks. It is particularly important to emphasize that... Figure 3 In order to show where effective ink marks can be produced, the imprint band 13 and the elastic band 9 are drawn alternately in areas where effective ink marks will not be produced even when they come into contact. In actual measurement, the imprint band 13 and the elastic band 9 will still come into contact in these areas, but because the contact force is small, it is not enough to form effective ink marks (or ink marks with obvious characteristics), so there will be no interference with qualitative identification.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
