Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing technology, specifically to a grinding wheel machine with automatic lifting function. Background Technology

[0002] Grinding wheels are a common basic device in the mechanical field, often used in grinding, cutting, dressing and other processes. There is a little trick when using grinding wheels: when the operator holds the workpiece and grinds it on the surface of the grinding wheel, he can move the workpiece up, down and left and right. This allows the entire working surface of the grinding wheel to participate in grinding evenly, avoiding excessive wear in some areas, thereby obtaining a flatter and smoother workpiece surface and reducing vibration marks or scratches.

[0003] For example, Chinese invention patent CN112775800A discloses a grinding wheel machine, including a base, a frame, a worktable, a grinding wheel assembly, a control lever, a sliding assembly, and a locking assembly. The frame is mounted on the base, and the worktable is mounted on the base for placing the workpiece to be processed. The grinding wheel assembly includes a grinding wheel, which is rotatably connected to the frame. The control lever is rotatably connected to the frame, with one end of the control lever located outside the frame. The grinding wheel assembly slides on the frame to position the grinding wheel assembly outside the frame. The locking assembly is located between the control lever and the frame to control the locking and unlocking of the control lever. In this embodiment of the invention, the combined action of the sliding assembly and the locking assembly pushes the grinding wheel to slide on the frame, causing the grinding wheel to protrude outside the frame, making it easier for workers to clean the outer surface of the grinding wheel.

[0004] Analysis of existing technologies and the above-mentioned invention patents reveals that existing grinding machines are often fixed in one position during operation. This makes it easy for the surface of the workpiece to develop vibration marks or scratches. Operators need to manually control the workpiece to move it up, down, left, and right to reduce vibration marks or scratches. It can also make the entire working surface of the grinding wheel participate in grinding evenly, avoiding excessive wear of the grinding wheel in certain areas, thereby obtaining a flatter and smoother workpiece surface. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a grinding wheel machine with an automatic lifting function. This solves the problem mentioned in the background art, where existing grinding wheel machines are often fixed in one position during operation, which easily leads to vibration marks or scratches on the surface of the workpiece. Operators need to manually control the workpiece to move it up, down, left, and right to reduce vibration marks or scratches. This invention also allows the entire working surface of the grinding wheel to participate in grinding evenly, avoiding excessive wear of the grinding wheel in certain areas, thereby obtaining a smoother and flatter workpiece surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding wheel machine with automatic lifting function, comprising: A frame, within which a worm gear is rotatably mounted; A grinding wheel is slidably sleeved with one end of the worm gear and can rotate synchronously with the worm gear; one end of the grinding wheel is also equipped with a lifting slot; and The lifting assembly is arranged within the frame, with one end engaging with the worm gear and the other end engaging with the lifting slot.

[0007] Furthermore, at least one pin is fixedly installed at one end of the worm gear, and the other end is fixedly connected to the motor output shaft.

[0008] Furthermore, a keyway is provided at one end of the grinding wheel, and the keyway engages with the key.

[0009] Furthermore, the lifting assembly includes: A gear is rotatably disposed within the frame and meshes with the worm gear; At least one eccentric wheel is provided and fixedly installed at both ends of the gear; and A rocker arm, one end of which is rotatably mounted on the eccentric wheel.

[0010] Furthermore, the lifting assembly also includes a swing bracket, at least one of which is provided. The swing bracket is rotatably connected to the rocker arm, and one end of the swing bracket is hinged to the frame, while the other end is provided with a slide bar, which is engaged with the lifting slot.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The worm gear of this device not only provides power for the rotation of the grinding wheel, but also drives the lifting component, which in turn moves the grinding wheel up and down. This eliminates the need for an additional power source and expands the device with a lifting function at a minimal cost. As a result, when grinding a workpiece, the worker only needs to focus on fixing the workpiece while moving it up, down, left, and right. This allows the entire working surface of the grinding wheel to participate in grinding evenly, avoiding excessive wear in certain areas. This results in a smoother and flatter workpiece surface, reduces vibration marks or scratches, and improves grinding efficiency. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0016] Example: like Figure 1 , 2 As shown, this utility model provides a grinding wheel machine with automatic lifting function, including a frame 101, a worm gear 102 rotatably mounted on the frame 101, a lifting component inside the frame 101, a grinding wheel 103 slidably sleeved on one end of the worm gear 102, a lifting slot 107 fixedly mounted on one end of the grinding wheel 103, one end of the lifting component engaging with the worm gear 102, and the other end engaging with the lifting slot 107.

[0017] At least one key 104 is fixedly installed at one end of the worm gear 102, and the other end is fixedly connected to the output shaft of the motor 105. One end of the grinding wheel 103 has a keyway 106, and the keyway 106 is engaged with the key 104. In this way, when the motor 105 drives the worm gear 102 to rotate, the worm gear 102 drives the grinding wheel 103 to rotate through the engagement of the key 104 and the keyway 106. While maintaining its own rotation, the grinding wheel 103 can also slide on the key 104.

[0018] like Figures 1 to 3 As shown, the lifting assembly includes a gear 201, an eccentric wheel 202, a swing bracket 203, a rocker arm 204, and a slide bar 205. The gear 201 and the swing bracket 203 are rotatably mounted on the frame 101. At least one eccentric wheel 202 is fixedly installed at both ends of the gear 201, and the gear 201 meshes with the worm gear 102. The rocker arm 204 is rotatably connected to the eccentric wheel 202. One end of the swing bracket 203 is hinged to the frame 101, and the other end is equipped with a slide bar 205. The slide bar 205 is locked in the lifting slot 107. The swing bracket 203 is also hinged to one end of the rocker arm 204.

[0019] When the worm gear 102 rotates, the gear 201 meshing with it begins to rotate. Since the eccentric wheel 202 is mounted on the gear 201 and the two are not on the same axis, the eccentric wheel 202 will have a swing amplitude when the gear 201 rotates. The rocker arm 204 sleeved on the eccentric wheel 202 also begins to swing and drives the swing bracket 203 hinged to it to move up and down. Since a slide bar 205 is fixedly installed at one end of the swing bracket 203 and the slide bar 205 is engaged in the lifting slot 107, the lifting slot 107 begins to move up and down, thereby driving the grinding wheel 103 to move up and down as a whole. The worm gear 102 of this device not only provides power for the rotation of the grinding wheel 103, but also drives the lifting assembly, which in turn drives the grinding wheel 103 to rise and fall without the need for an additional power source. This expands the device with a lifting function with minimal equipment cost. In this way, when grinding a workpiece, the worker only needs to focus on fixing the workpiece to move it up, down, left, and right, so that the entire working surface of the grinding wheel 103 participates in grinding evenly, avoiding excessive wear in certain areas. This results in a smoother and flatter workpiece surface, reduces vibration marks or scratches, and improves the grinding efficiency of the grinding machine.

[0020] The specific usage and beneficial effects of this utility model are as follows: The operator starts the motor 105, which drives the worm gear 102 to rotate. The worm gear 102 is engaged with the keyway 106 via the key 104, which drives the grinding wheel 103 to rotate. While maintaining its own rotation, the grinding wheel 103, in conjunction with the eccentric wheel 202 and the gear 201 which are not on the same axis, causes the eccentric wheel 202 to swing when the gear 201 rotates. The rocker arm 204, which is sleeved on the eccentric wheel 202, also begins to swing, driving the swing bracket 203, which is hinged to it, to move up and down. Since a slide bar 205 is fixedly installed at one end of the swing bracket 203 and is engaged in the lifting slot 107, the lifting slot 107 begins to move up and down, thereby driving the grinding wheel 103 to move up and down as a whole. This allows the entire working surface of the grinding wheel 103 to participate in grinding evenly, avoiding excessive wear in certain areas, thus obtaining a smoother and flatter workpiece surface, reducing vibration marks or scratches, and improving the grinding efficiency of the grinding machine.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
