Description

Technical Field

[0001] This utility model relates to the technical field of glass edging equipment, and in particular to a quick-change grinding wheel mechanism and its double-sided rounding edge grinding machine. Background Technology

[0002] In the glass processing industry, double-sided edge grinding machines are commonly used to perform fine grinding on the edges of glass to remove burrs, smooth edges, or form specific shapes. To ensure operator safety and prevent debris from splashing out during grinding, the grinding wheels are typically installed within a closed protective enclosure. However, while this design provides safety, it also presents challenges for replacing and maintaining the grinding wheels.

[0003] In traditional grinding wheel replacement processes, operators typically need to first lift the grinding wheel out of the protective cover, then rotate it away from the work area, and finally remove it from the machine or install a new grinding wheel. This movement process requires a transmission mechanism, with the sleeve and the sliding sleeve fitted outside the sleeve being the key transmission components. These components are designed to achieve lifting and rotation, thereby driving the raising and rotation of the grinding wheel.

[0004] However, in actual operation, if the sliding sleeve rotates before it is raised to a certain safe height relative to the sleeve, the grinding wheel may be rotated before it is fully extended from the protective cover. This may cause the grinding wheel to collide with the protective cover or other components, resulting in damage to the equipment. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a quick grinding wheel replacement mechanism and a double-sided grinding and rounding machine, which can only drive the grinding wheel assembly to rotate away from the working area after the sliding sleeve drives the grinding wheel assembly to be raised to the position, so as to prevent the grinding wheel assembly from accidentally rotating and colliding with other parts of the machine body.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A quick-change grinding wheel mechanism includes,

[0008] Grinding wheel assembly;

The two ends of the connecting arm are connected to the grinding wheel assembly and the sliding sleeve, respectively. The sliding sleeve drives the grinding wheel assembly to rotate during rotation. The sliding sleeve has a locking element, and the sleeve has a locking part and an unlocking part. The locking element connects with the locking part or the unlocking part during the lifting and lowering of the sliding sleeve, so that the sliding sleeve is in a locked or unlocked state. In the unlocked state, the sliding sleeve is rotatable relative to the sleeve; in the locked state, the rotation of the sliding sleeve is restricted.

[0010] Furthermore, the unlocking part is an annular groove, which surrounds the outer periphery of the sleeve; the locking part is a locking groove, which extends vertically and communicates with the annular groove; the locking member includes a locking pin, which is inserted into the locking groove; the sliding sleeve is used to drive the locking pin to slide along the locking groove during lifting and lowering, and the sliding sleeve is used to drive the locking pin to slide along the annular groove during rotation.

[0012] Furthermore, the sliding sleeve is provided with a locking hole, and the locking pin is slidably connected to the locking hole; the locking component also includes a locking handle, which is connected to the locking pin, and the locking handle is used to drive the locking pin away from the locking groove under the action of external force.

[0013] Furthermore, the rotating assembly includes a first lead screw, which is rotatably connected to the sliding sleeve and screwed to the sleeve. The first lead screw is used to drive the sliding sleeve to rise and fall relative to the sleeve during rotation.

[0014] Furthermore, the sliding sleeve is provided with a mounting flange, which is fixedly connected to the sliding sleeve; the first lead screw is rotatably inserted through the middle of the mounting flange; and an adjusting handwheel is provided at the upper end of the first lead screw.

[0015] Furthermore, it includes a propulsion assembly, which includes a push plate, a fixed plate, and a second lead screw. The rotation assembly is disposed on the push plate, and the second lead screw is screwed to the fixed plate and rotatably connected to the push plate.

[0016] Furthermore, a connecting plate is provided at the bottom of the sleeve, and the connecting plate is connected to the push plate; a telescopic protective sleeve is provided between the periphery of the connecting plate and the bottom of the sliding sleeve.

[0017] Furthermore, the grinding wheel assembly includes a mounting housing, a grinding wheel, a motor, and a rotating shaft. The motor and the rotating shaft are mounted inside the mounting housing, and the grinding wheel is detachably connected to the bottom end of the rotating shaft. The motor is used to drive the rotating shaft. The connecting arm connects the mounting housing and the sliding sleeve.

They are only for the convenience of describing this utility model and 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 this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Example 1

[0033] See Figures 1 to 3 This utility model discloses a quick-change grinding wheel mechanism, which includes a grinding wheel assembly 1 and a rotating assembly. Specifically, the rotating assembly includes a sliding sleeve 20, a sleeve 21, and a connecting arm 22. The sliding sleeve 20 is sleeved on the outside of the sleeve 21, and the sliding sleeve 20 is rotatable and height-adjustable relative to the sleeve 21. (See reference...) Figure 1 The two ends of the connecting arm 22 are connected to the grinding wheel assembly 1 and the sliding sleeve 20 respectively. The sliding sleeve 20 is used to drive the grinding wheel assembly 1 to rotate during the rotation process.

[0034] Therefore, due to the connecting function of the connecting arm 22, when the sliding sleeve 20 is raised or rotated relative to the sleeve 21, the sliding sleeve 20 can drive the grinding wheel assembly 1 to be raised or rotated. And when the sliding sleeve 20 drives the grinding wheel assembly 1 to rotate away from the working area, the grinding wheel of the grinding wheel assembly 1 can be disassembled and replaced.

[0035] Furthermore, see Figure 2 The sliding sleeve 20 is equipped with a locking element 30, see reference. Figure 3The sleeve 21 is provided with a locking part 31 and an unlocking part 32. The locking member 30 is used to connect with the locking part 31 or the unlocking part 32 during the lifting and lowering of the sliding sleeve 20, so that the sliding sleeve 20 is in a locked state or an unlocked state. In the unlocked state, the sliding sleeve 20 can rotate relative to the sleeve 21; in the locked state, the rotation of the sliding sleeve 20 is restricted.

[0036] Based on this structure, when using the quick-change grinding wheel mechanism of this utility model, the locking member 30 is connected to the locking part 31 on the sleeve 21 in the initial state, so that the sliding sleeve 20 is in a locked state. At this time, the sliding sleeve 20 cannot rotate, but can be raised and lowered.

[0037] When the grinding wheel assembly 1 needs to be replaced, first raise the sliding sleeve 20 relative to the sleeve 21 to gradually separate the locking member 30 from the locking part 31; simultaneously, the sliding sleeve 20 drives the grinding wheel assembly 1 to rise via the connecting arm 22. When the sliding sleeve 20 reaches its position, the locking member 30 connects with the unlocking part 32 and switches to the unlocked state; in the unlocked state, the sliding sleeve 20 can rotate, thereby driving the grinding wheel assembly 1 to rotate via the connecting arm 22, causing it to move away from the grinding wheel working area. Subsequently, the operator can disassemble or install the grinding wheel.

[0038] Since the sliding sleeve 20 first drives the grinding wheel assembly 1 to rise and then drives the grinding wheel assembly 1 to rotate, the grinding wheel assembly 1 rotates after leaving the protective cover, which can prevent the grinding wheel assembly 1 from colliding with other parts of the frame 2 during rotation.

[0039] After the grinding wheel replacement is completed, the grinding wheel assembly 1 is rotated back to the working area by rotating the sliding sleeve 20. Then, the sliding sleeve 20 descends, driving the grinding wheel assembly 1 back to its original position. During the descent of the sliding sleeve 20, the locking member 30 contacts and locks with the locking part 31 again, preventing the sliding sleeve 20 from rotating. This prevents the sliding sleeve 20 from driving the grinding wheel assembly 1 to rotate without authorization, thus ensuring the safety and stability of the grinding wheel assembly 1 in the working state.

[0040] It should be noted that the distance between the locking part 31 and the unlocking part 32 is constant, and the height to which the sliding sleeve 20 drives the grinding wheel assembly 1 to rise and fall is always the same each time. After replacing the grinding wheel assembly 1 and locking it again, the height of the grinding wheel assembly 1 is the same as the previous working height. At this time, the grinding wheel assembly 1 can be put into operation directly after replacing the grinding wheel without any position adjustment. That is, the connection between the locking part 30 and the locking part 31 plays a positioning role.

[0041] Therefore, through the cooperation of the locking member 30 with the locking part 31 and the unlocking part 32, when the sliding sleeve 20 rises to its position, the locking member 30 automatically switches to the unlocked state, allowing the sliding sleeve 20 to rotate freely. Simply driving the sliding sleeve 20 to rotate allows the grinding wheel assembly 1 to be moved away from the working area via the connecting arm 22 for disassembly or installation of the grinding wheel. This process is efficient and quick, improving work efficiency, and the locking and unlocking transitions can be completed without manual intervention. When the sliding sleeve 20 descends, the locking member 30 automatically switches to the locked state, preventing accidental rotation of the sliding sleeve 20, thereby preventing collisions between the grinding wheel and the protective cover or other components, and improving operational safety.

[0042] Further, see again Figure 3 The unlocking part 32 is an annular groove that surrounds the outer periphery of the sleeve 21; the locking part 31 is a locking groove that extends vertically and communicates with the annular groove. Furthermore, the locking member 30 includes a locking pin 33, which is inserted into the locking groove. The sliding sleeve 20 is used to drive the locking pin 33 to slide along the locking groove during lifting and lowering, and also to drive the locking pin 33 to slide along the annular groove during rotation.

[0043] Based on this structure, when the locking pin 33 in the locking member 30 is inserted into the locking groove on the sleeve 21, since the locking groove extends vertically, the locking pin 33 can only slide up and down within the locking groove, thus guiding the sliding sleeve 20 to only perform lifting and lowering movements. At this time, the sliding sleeve 20 is locked and cannot rotate. When the locking pin 33 enters the through-hole between the locking groove and the annular groove, the locking pin 33 can enter the annular groove and slide along the extending direction of the annular groove, guiding the sliding sleeve 20 to perform rotational movements.

[0044] Therefore, this application restricts the movement path of the locking pin 33 by using the shapes of the locking groove and the annular groove, thereby enabling the sliding sleeve 20 to achieve the desired movement. The locking groove extends vertically, ensuring that the locking pin 33 can slide stably and unobstructed during the lifting and lowering of the sliding sleeve 20. The annular groove surrounds the outer periphery of the sleeve 21, ensuring that the locking pin 33 can slide stably and unobstructed, thereby enabling the sliding sleeve 20 to rotate stably.

[0045] It should be noted that the annular groove and the locking groove are connected, so that when the locking pin 33 slides to the through-hole between the two, the sliding sleeve 20 can switch between the locked state and the unlocked state, realizing the automatic unlocking and locking function of the sliding sleeve 20.

[0046] In addition, the locking pin 33 can be integrally formed on the inner peripheral wall of the sleeve 21.

[0047] Furthermore, an annular groove is provided at the upper end of the locking groove.

[0048] Specifically, when the sliding sleeve 20 rises, the locking pin 33 first slides along the locking groove; once the rise of the sliding sleeve 20 is restricted, the locking pin 33 enters the connection between the locking groove and the annular groove. At this time, the sliding sleeve 20 can be rotated, and the locking pin 33 will enter the annular groove.

[0049] It should be noted that the advantage of this setting is that when using it, there is no need to determine the specific position of the locking pin 33. You only need to rotate the sliding sleeve 20 when the sliding sleeve 20 is blocked from rising, so that the locking pin 33 can automatically switch from the locked state to the unlocked state. This is suitable for manual operation.

[0050] This ensures that the sliding sleeve 20 will only unlock when it rises to a specific position, avoiding the risk of accidental unlocking during the lifting and lowering process, and ensuring the sequential nature of unlocking and locking. The through-type locking groove and annular groove not only automatically switch between locking and unlocking, but also serve as guides and positions, directing the locking pin 33 to slide along a specific trajectory.

[0051] Further, see Figure 3 The sliding sleeve 20 is provided with a locking hole 34, and the locking pin 33 is slidably connected to the locking hole 34. In addition, the locking member 30 also includes a locking handle 35, and the locking handle 35 is connected to the locking pin 33. The locking handle 35 is used to drive the locking pin 33 away from the locking groove under the action of external force.

[0052] When it is necessary to separate the sliding sleeve 20 from the sleeve 21, first grasp the locking handle 35; then, apply external force away from the locking groove, and the locking handle 35 will drive the locking pin 33 to slide within the locking hole 34. As the locking pin 33 slides, it gradually disengages from the locking groove, at which point the sliding sleeve 20 and the sleeve 21 can be separated from each other.

[0053] Thus, by manually operating the locking handle 35, the connection between the locking part 30 and the locking part 31 or the unlocking part 32 can be released, thereby enabling the disassembly and maintenance of the sliding sleeve 20 and the sleeve 21.

[0054] Further, see Figure 2 The rotating assembly includes a first lead screw 23. Specifically, the first lead screw 23 is rotatably connected to the sliding sleeve 20 and screwed to the sleeve 21. The first lead screw 23 is used to drive the sliding sleeve 20 to rise and fall relative to the sleeve 21 during rotation.

[0055] Based on this structure, when it is necessary to raise or lower the sliding sleeve 20, the first lead screw 23 can be rotated by an external power source (such as a motor, handle, etc.). As the first lead screw 23 rotates, its threads interact with the threads inside the sleeve 21, generating axial thrust or pull. Under the action of the thrust or pull generated by the rotation of the first lead screw 23, the sliding sleeve 20 begins to slide along the axial direction of the first lead screw 23.

[0056] Therefore, precise position control can be achieved by rotating the first lead screw 23 to drive the sliding sleeve 20 to rise and fall. Specifically, when the first lead screw 23 is driven by a motor, the motor can automatically drive the first lead screw 23 to rotate a certain number of revolutions, thereby causing the sliding sleeve 20 to rise and fall to the unlocked position or the locked position accordingly. The grinding wheel can be replaced in the unlocked position.

[0057] The threaded connection between the first lead screw 23 and the sleeve 21 has high strength and stability, which can ensure that the structure will not shake or deform during the lifting and lowering of the sliding sleeve 20, thereby ensuring the stability and safety of the equipment.

[0058] Furthermore, the sliding sleeve 20 is provided with a mounting flange 24, specifically, the mounting flange 24 is fixedly connected to the sliding sleeve 20. The first lead screw 23 is rotatably inserted through the middle of the mounting flange 24, and an adjusting handwheel is provided at the upper end of the first lead screw 23.

[0059] The periphery of the mounting flange 24 can be connected to the top of the sliding sleeve 20 by fasteners such as screws and bolts. The mounting flange 24 has a mounting hole in the middle, and the first lead screw 23 passes through the mounting hole. A rolling bearing is provided between the first lead screw 23 and the mounting hole so that the first lead screw 23 can rotate relative to the mounting flange 24 and the sliding sleeve 20.

[0060] Therefore, the first lead screw 23 can be rotated by manually adjusting the handwheel. At the same time, a position sensor can be installed on the sliding sleeve 20 to detect the height of the sliding sleeve 20 in real time. After detecting that the sliding sleeve 20 has reached the unlocking height, the sliding sleeve 20 can be manually rotated to drive the grinding wheel assembly 1 to rotate out or into the working area.

[0061] Furthermore, the quick-change grinding wheel mechanism includes a propulsion assembly, specifically comprising a push plate 40, a fixed plate 41, and a second lead screw 42. The aforementioned rotating assembly is mounted on the push plate 40, and the second lead screw 42 is screwed to the fixed plate 41, and the second lead screw 42 is rotatably connected to the push plate 40. Additionally, the fixed plate 41 is used to connect to the frame 2. The second lead screw 42 drives the push plate 40 and its rotating assembly to move back and forth during rotation.

[0062] Based on this structure, when using the propulsion assembly, the second lead screw 42 can be rotated by turning the handle or by driving the motor. Since the second lead screw 42 is screwed to the fixed plate 41 and the fixed plate 41 is fixed on the frame 2, the rotation of the second lead screw 42 can drive the push plate 40 to move back and forth along the axis of the second lead screw 42, thereby driving the entire rotating assembly to move back and forth.

[0063] Since the sliding sleeve 20 of the rotating component is connected to the grinding wheel assembly 1 via the connecting arm 22, the sliding sleeve 20 can drive the grinding wheel assembly 1 to move back and forth when it is driven by the push plate 40. Therefore, by setting up the propulsion component, the grinding wheel assembly 1 can be moved closer to or further away from the frame 2, and after moving away from the frame 2, it is convenient to replace the grinding wheel. Simultaneously, when the grinding wheel assembly 1 is in the working area, the propulsion component can adjust the front-back position of the grinding wheel assembly 1, thereby adjusting its working position and changing its working mode.

[0064] In addition, the second lead screw 42 is connected to the push plate 40 via a rolling bearing, thereby enabling the second lead screw 42 to rotate relative to the push plate 40.

[0065] Furthermore, the bottom of the sleeve 21 is provided with a connecting plate 25, and the connecting plate 25 is connected to the push plate 40. Among them, a telescopic protective sleeve 26 is provided between the periphery of the connecting plate 25 and the bottom of the sliding sleeve 20.

[0066] The connecting plate 25 is securely connected to the push plate 40 by bolts or other fastening methods to ensure that it will not loosen or fall off during operation, so that the movement of the push plate 40 can drive the sleeve 21 and its components to move together. In addition, the telescopic protective sleeve 26 can be a corrugated pipe, rubber hose, etc., which can extend and retract with the rise and fall of the sliding sleeve 20, always keeping the periphery of the connecting plate 25 wrapped and protected, preventing dust or rainwater from entering the interior of the sleeve 21.

[0067] Furthermore, the grinding wheel assembly 1 includes a mounting housing 11, a grinding wheel 12, a motor, and a rotating shaft 13. Specifically, the motor and the rotating shaft 13 are mounted inside the mounting housing 11, and the grinding wheel 12 is detachably connected to the bottom end of the rotating shaft 13. The motor is used to drive the rotating shaft 13, and the aforementioned connecting arm 22 connects the mounting housing 11 and the sliding sleeve 20.

[0068] Based on this structure, during assembly, the motor and rotating shaft 13 are installed into the mounting housing 11, and then the grinding wheel 12 is detachably connected to the bottom end of the rotating shaft 13. Furthermore, the connecting arm 22 needs to be installed between the mounting housing 11 and the sliding sleeve 20. Specifically, the connecting arm 22 includes a vertical plate and two horizontal plates. The vertical plate is fixedly connected to the mounting housing 11, and the two horizontal plates are spaced apart on the vertical plate, with both ends of the horizontal plates connected to the vertical plate and the sliding sleeve 20, respectively.

[0069] The motor is the power source that drives the rotating shaft 13 to rotate, and the rotating shaft 13 is responsible for driving the grinding wheel 12 to perform grinding operations. The connecting arm 22 plays a supporting and force-transmitting role, ensuring that the grinding wheel assembly 1 can move and rotate stably during operation.

[0070] Specifically, the grinding wheel 12 and the rotating shaft 13 can be connected by fasteners such as screws and bolts. Alternatively, a limiting groove can be provided at the bottom of the rotating shaft 13, and a limiting protrusion can be provided in the middle of the grinding wheel 12, so that the limiting protrusion and the limiting groove are mutually limited and connected in the circumferential direction. In this way, when the rotating shaft 13 rotates, it can drive the grinding wheel 12 to rotate to perform grinding work.

[0071] Therefore, when the sliding sleeve 20 drives the mounting shell 11 to rotate and exit the working area via the connecting arm 22, the grinding wheel 12 at the bottom of the rotating shaft 13 can be removed and replaced. After replacement, the mounting shell 11 is rotated into the working area via the sliding sleeve 20 and the connecting arm 22.

[0072] Example 2

[0073] See Figure 4 This utility model also discloses a double-sided grinding and rounding machine, which includes a frame 2. Specifically, both sides of the frame 2 are provided with a quick-change grinding wheel mechanism as shown in Embodiment 1.

[0074] When the glass to be processed is placed in the middle of the frame 2, the grinding wheels on both sides of the frame 2 can grind both sides of the glass to be processed. When it is necessary to replace the grinding wheel 12, the grinding wheel assembly 1 is rotated away from the frame 2 by the rotating component of the grinding wheel quick change mechanism. After replacing the grinding wheel 12, the grinding wheel assembly 1 is rotated back to the side of the frame 2.

[0075] Each side of the frame 2 can be equipped with multiple quick-change grinding wheel mechanisms according to processing requirements. When one of the grinding wheels needs to be replaced, the equipment does not need to be stopped. The grinding wheel to be replaced can be rotated away from the working area through the individual quick-change grinding wheel mechanism, so as to replace the grinding wheel without stopping the machine.

[0076] It should be noted that the working structure and principle of the specific quick-change grinding wheel mechanism are the same as those in Embodiment 1, while the other structures of the double-sided grinding and rounding machine are existing technologies and will not be described in detail here.

[0077] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
