Description

Technical Field

[0001] This utility model relates to the field of grinding disc testing technology, and in particular to a grinding disc testing and replacement device. Background Technology

[0002] Grinding discs, also known as abrasive wheels or grinding wheels, are tools used for grinding, cutting, and polishing materials. After use, grinding discs wear down, causing their diameter and thickness to shrink. Once they reach a certain size, they must be discarded. Therefore, grinding discs need to be inspected and replaced regularly.

[0003] In existing technology, operators need to use measuring tools to inspect the grinding discs, then manually place the scrapped discs into a waste bin, and subsequently find replacement discs of the same model for use. Manual inspection is cumbersome, susceptible to human measurement errors, and each replacement requires time to find a suitable disc, making it both time-consuming and labor-intensive.

[0004] Therefore, there is an urgent need for a grinding disc inspection and replacement device to solve the above problems. Utility Model Content

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] like Figures 1-4As shown, in this embodiment, the grinding disc inspection and replacement device includes a housing 1, a waste bin 2, multiple supply components 3, and multiple switches 4. The waste bin 2 is disposed within the housing 1 and has multiple inspection holes 21. The width or length of the inspection holes 21 differs among them, and the inspection holes 21 are used to verify whether a grinding disc of a corresponding specification can pass through. Each of the multiple supply components 3 corresponds to a different specification of replacement grinding disc. Each supply component 3 includes a lifting mechanism and a support plate 31. The lifting mechanism is disposed inside the housing 1 and connected to the support plate 31, driving the support plate 31 to lift and lower, so that the support plate 31 pushes the placed replacement grinding disc outside the housing 1. Each of the multiple switches 4 corresponds to a different inspection hole, and each of the multiple switches 4 is electrically connected to a different power supply circuit of the lifting mechanism. The switches 4 are used to control the opening or closing of the lifting mechanism.

[0043] The waste bin 2 is located on the top of the housing 1. Multiple detection holes 21 are provided on the top of the waste bin 2. These detection holes 21 vary in width, length, or both. The type of grinding disc to be tested corresponds one-to-one with the number of detection holes 21. Specifically, the width of the detection hole 21 matches the width of the corresponding model of grinding disc, and the length matches the outer diameter of the corresponding model of grinding disc when its wear reaches the scrap standard. When the diameter and thickness of the grinding disc to be tested are smaller than the length and width of the corresponding detection hole 21, the grinding disc can pass through the detection hole 21 and enter the waste bin 2, indicating that the grinding disc is scrap and cannot be used further. Conversely, when the diameter and thickness of the grinding disc to be tested are larger than the length and width of the corresponding detection hole 21, the grinding disc cannot pass through the detection hole 21, indicating that the grinding disc can still be used normally. This avoids errors caused by manual measurement and improves testing efficiency. Multiple supply components 3 are arranged side-by-side inside the housing 1, corresponding one-to-one with various types of grinding discs. The lifting mechanism is a combination of a motor drive and a lead screw, or an electric telescopic rod, etc. The fixed end of the lifting mechanism is located at the bottom of the housing 1, and the driving end is connected to a support plate 31 to drive the support plate 31 to move vertically. Unused grinding discs of the corresponding type are placed on the support plate 31. Multiple switches 4 are arranged beside the corresponding detection holes 21, and each switch 4 corresponds to a power supply circuit of one of the lifting mechanisms. This allows operators to easily press the switch 4 corresponding to the detection hole 21 to retrieve a replacement grinding disc corresponding to the scrapped model, saving time in searching for the same model and improving work efficiency. Optionally, the waste bin 2 is located inside the housing 1, making the grinding disc detection and replacement device compact and improving the utilization of the external space of the housing 1.

[0044] The working principle of this grinding disc testing and replacement device is as follows: First, the operator inserts multiple grinding discs of different models into the corresponding testing holes 21. The size of the testing holes 21 corresponds to the qualified grinding discs. When the grinding disc can be inserted into the testing hole 21 and enter the waste bin 2, the operator presses the switch 4 next to the testing hole 21. Switch 4 connects the power supply circuit of the lifting mechanism, and the lifting mechanism drives the pallet 31 to rise vertically. This pushes the top layer of replacement grinding discs stacked on the pallet 31 out of the housing 1. Releasing switch 4 disconnects the power supply circuit of the lifting mechanism, and the pallet 31 stops rising, allowing the operator to easily retrieve and replace the replacement grinding disc. When the grinding disc cannot be inserted into the testing hole 21 and cannot enter the waste bin 2, it indicates that the grinding disc can continue to be used, and there is no need to press switch 4.

[0045] Preferably, the switch 4 includes a first button section and a second button section, which are respectively located on both sides of the same detection hole 21. The operator must press both the first button section and the second button section simultaneously to control the lifting mechanism, thus preventing accidental operation. Preferably, the grinding disc detection and replacement device also includes a timer, which is electrically connected to the lifting mechanism and the switch 4. When the switch 4 is pressed, the lifting mechanism starts working. At the same time, the timer automatically shuts down the lifting mechanism according to its preset time, ensuring that the lifting mechanism drives the pallet 31 to rise the same distance each time.

[0046] Reference Figure 3 The lifting mechanism includes a rotary drive source 33 and a connecting member 34. The rotary drive source 33 is disposed in the housing 1, and its output end is connected to the connecting member 34. The support plate 31 has a connecting hole, and the connecting member 34 is threadedly connected to the connecting hole, so that the support plate 31 can move along the axial direction of the connecting member 34. The rotary drive source 33 is a motor, and the connecting member 34 is a lead screw with external threads on its outer circumference. The output end of the rotary drive source 33 is fixedly connected to one end of the connecting member 34. The connecting member 34 extends along the height direction of the housing 1, and the connecting hole of the support plate 31 has an internal thread, which is threadedly connected to the connecting member 34. When the switch 4 is triggered, the rotary drive source 33 corresponding to the switch 4 starts, and the rotary drive source 33 drives the connecting member 34 to rotate. The connecting member 34 is connected to the connecting hole of the support plate 31, so that the support plate 31 can rise vertically relative to the connecting member 34, thereby moving the replacement grinding disc upward and protruding outside the housing 1 for easy access by the operator. Optionally, the lifting mechanism is set as an electric telescopic rod, with the fixed end of the electric telescopic rod located at the bottom of the housing 1 and the telescopic end of the electric telescopic rod connected to the tray 31. When the switch 4 is triggered, the electric telescopic rod starts and can drive the tray 31 to lift.

[0047] Continue to refer to Figure 3The supply component 3 also includes a guide 32, which extends along the height of the housing 1 and is fixedly connected to the housing 1. The guide 32 passes through the support plate 31 and is used to mount multiple stacked replacement grinding discs. The guide 32 is configured as a limiting rod, passing through the support plate 31 and fixedly connected to the bottom of the housing 1. The support plate 31 can slide relative to the guide 32. Multiple stacked replacement grinding discs are mounted on the guide 32, which serves to limit the movement and prevent the replacement grinding discs from tilting or collapsing. Whenever the support plate 31 rises to a certain height, the topmost replacement grinding disc extends outside the housing 1 for easy access and replacement by the operator. The guide 32 guides the replacement grinding discs below to extend sequentially along its length.

[0048] Reference Figures 1-3 The grinding disc inspection and replacement device also includes a first end cover 5, which is rotatably mounted on the housing 1. The housing 1 has a first opening 11 located above the supply assembly 3. The first end cover 5 is used to open or close the first opening 11. When there are no extra grinding discs on the tray 31, the controller on the side of the housing 1 controls the rotary drive source 33 to drive the tray 31 to descend to the bottom, opening the first end cover 5. A new replacement grinding disc is placed on the tray 31, and the first end cover 5 is closed to prevent foreign objects from falling in, thus providing protection and facilitating subsequent retrieval. The first end cover 5 has a material retrieval port 51, which is correspondingly set to the tray 31. The material retrieval port 51 is used to retrieve the replacement grinding discs on the tray 31. The replacement grinding discs pushed out of the tray 31 can be retrieved through the material retrieval port 51 without opening the first end cover 5, making operation convenient.

[0049] Continue to refer to Figures 1-3 The grinding disc inspection and replacement device also includes a second end cover 6, which has an inspection hole 21. The second end cover 6 is rotatably mounted on the housing 1 and is used to open or close the opening of the waste bin 2. A fixed upright plate is provided on the housing 1. The second end cover 6 is rotatably mounted on the fixed upright plate via a rotating shaft. When there are too many grinding discs in the waste bin 2, the second end cover 6 is flipped over to open the opening of the waste bin 2, and the grinding discs in the waste bin 2 are taken out for recycling or disposal. Preferably, the waste bin 2 has an auxiliary groove 22 for hand insertion. The outer edge of the waste bin 2 is provided with a wing plate. The second end cover 6 is opened using the wing plates on both sides of the waste bin 2. The operator inserts both hands into the auxiliary grooves 22 on both sides of the waste bin 2 and uses the force to lift the waste bin 2 off the housing 1, and put the empty waste bin 2 back on the housing 1 to facilitate the continued inspection of the grinding discs.

[0050] Reference Figures 1-2The grinding disc inspection and replacement device also includes multiple wheels 10, which are rotatably mounted on the bottom of the housing 1. Driven by the movement of the wheels 10, the device can be moved to other inspection positions or grinding disc recycling positions via a handle mounted on a fixed upright plate. This provides high flexibility, eliminates the need for long-distance transport by operators, and saves time and effort.

[0051] Continue to refer to Figures 1-3 The grinding disc inspection and replacement device also includes a limiting frame 7, which is disposed on the housing 1. The waste bin 2 is snapped onto the limiting frame 7, and the limiting frame 7 is used to fix and limit the waste bin 2. In order to ensure the stability of the waste bin 2, the bottom of the waste bin 2 is snapped onto the limiting frame 7 to prevent the waste bin 2 from slipping off the housing 1 and damaging the device during the inspection or movement process.

[0052] The grinding disc inspection and replacement device also includes a storage box 8 and a third end cover 9. The storage box 8 is located inside the housing 1, and the housing 1 also has a second opening 12. The third end cover 9 is used to open or close the second opening 12. The storage box 8 is located in the receiving cavity of the housing 1 and serves to store materials. By opening the third end cover 9 and pulling out the storage box 8, operators can easily retrieve auxiliary materials or tools from the storage box 8.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
