Description

Technical Field

[0001] This utility model relates to the technical field of grinding wheel accessories, and in particular to a base adjustment mechanism. Background Technology

[0002] Benchtop grinding machines are commonly used to sharpen various cutting tools and implements. Besides sharing some common requirements with grinding machine tools, grinding machines are characterized by high speed, simple structure, wide applicability, and generally manual operation. Grinding machines are frequently used in tool manufacturing, but are often not operated by designated personnel, and some are poorly maintained. A significant proportion of injuries are caused by failure to adhere to safe operating procedures during grinding operations.

[0003] Currently, benchtop grinders are typically mounted by bolts directly to the tabletop. However, the strong vibrations generated during grinding can cause these bolts to loosen over time. Furthermore, since the grinder's angle cannot be adjusted once fixed to the base, when grinding irregularly shaped or large workpieces, only the workpiece's angle can be changed; the grinder's angle cannot be adjusted to accommodate the grinding process. Therefore, this invention proposes a base adjustment mechanism. Utility Model Content

[0008] Furthermore, a groove is provided at the bottom end of the support rod, and a roller is rotatably connected inside the groove.

[0009] Furthermore, a square rod is fixed to the top of the vertical shaft, a square tube is slidably connected to the top surface of the square rod, the top of the square tube is fixedly connected to the lower surface of the top plate, a slider is fixed to the side of the top of the square rod, a strip-shaped opening is opened on the side wall of the square tube, and the slider is slidably connected to the strip-shaped opening.

[0010] Furthermore, the adjustment assembly includes a worm gear fixed to the bottom of the vertical shaft and a horizontal shaft located inside the mounting base. The two ends of the horizontal shaft are rotatably connected to the side wall of the mounting base via bearings. A worm is fixedly connected to the middle of the horizontal shaft, and the worm meshes with the worm gear. A knob is fixedly connected to one end of the horizontal shaft through the side wall of the mounting base.

[0011] Furthermore, the fixing component is located near the knob and includes a side plate fixed to the surface of the mounting base.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a base adjustment mechanism is disclosed, including a mounting base 1. The bottom of the mounting base 1 is hollow, and a top plate 2 is provided on the top of the mounting base 1. The top plate 2 has mounting holes for mounting a grinding wheel base. Multiple support components 3 are fixed to the side of the lower surface of the top plate 2. A vertical shaft 4 is rotatably connected to the top wall of the mounting base 1 through a bearing. The top of the vertical shaft 4 is connected to the lower surface of the top plate 2 by a linkage component 5. An adjustment component 6 for driving the vertical shaft 4 to rotate is installed inside the mounting base 1. A cushioning sponge 7 is fixed to the lower surface of the top plate 2. A fixing component 8 is installed on the top of the outer side wall of the mounting base 1.

[0024] A base plate 9 is fixed to the outer wall of the bottom end of the mounting base 1, and mounting holes are provided on the base plate 9.

[0025] The base plate 9 can be fixedly installed through the mounting holes, thereby realizing the installation and fixation of the mechanism.

[0026] The support assembly 3 includes a circular tube 31 fixed to the lower surface of the top plate 2. A spring 32 is fixed to the inner top wall of the circular tube 31. A support rod 33 is fixedly connected to the bottom end of the spring 32. The support rod 33 is in contact with the inner side wall of the circular tube 31 and is slidably connected to the circular tube 31.

[0027] The support component 3 provides support at the bottom of the top plate 2. The spring 32, together with the friction between the support rod 33 and the round tube 31 and the buffer sponge 7, can reduce the vibration of the grinding wheel on the surface of the top plate 2, thereby achieving the shock absorption effect.

[0028] The bottom end of the support rod 33 has a groove 34, and a roller 35 is rotatably connected inside the groove 34.

[0029] When the top plate 2 rotates, the roller 35 can reduce the friction between the support rod 33 and the upper surface of the mounting base 1.

[0030] A square rod 51 is fixed at the top of the vertical shaft 4. A square tube 52 is slidably connected to the top surface of the square rod 51. The top of the square tube 52 is fixedly connected to the lower surface of the top plate 2. A slider 53 is fixed to the side of the top of the square rod 51. A strip-shaped opening 54 is opened on the side wall of the square tube 52. The slider 53 is slidably connected to the strip-shaped opening 54.

[0031] The square rod 51 and square tube 52 can transmit torque. When the vertical shaft 4 rotates, it can drive the top plate 2 to rotate synchronously. By setting the slider 53 and the strip opening 54, the square tube 52 can be prevented from separating from the square rod 51.

[0032] The adjustment assembly 6 includes a worm gear 63 fixed to the bottom of the vertical shaft 4 and a horizontal shaft 61 located inside the mounting base 1. Both ends of the horizontal shaft 61 are rotatably connected to the side wall of the mounting base 1 via bearings. A worm 62 is fixedly connected to the middle of the horizontal shaft 61, and the worm 62 meshes with the worm gear 63. A knob 64 is fixedly connected to one end of the horizontal shaft 61 through the side wall of the mounting base 1.

[0033] By rotating the knob 64, the horizontal shaft 61 is rotated, and the worm gear 62 on the horizontal shaft 61 drives the worm wheel 63 to rotate, thereby realizing the rotation of the vertical shaft 4.

[0034] The fixing component 8 is located on the side near the knob 64. The fixing component 8 includes a side plate 81 fixed to the surface of the mounting base 1. A screw 82 is threaded through the middle of the side plate 81. A pressure plate 83 is rotatably connected to the bottom end of the screw 82 via a bearing. The pressure plate 83 is located directly above the horizontal axis 61.

[0035] After adjusting the rotation angle of the top plate 2, the pressure plate 83 can be driven by turning the screw 82 to press the horizontal shaft 61, thereby locking the horizontal shaft 61.

[0036] Working principle: The base of the grinding wheel machine can be fixed to the upper surface of the top plate 2 with bolts. During use, the horizontal shaft 61 can be rotated by turning the knob 64. The horizontal shaft 61 drives the vertical shaft 4 to rotate through the meshing of the worm gear 62 and worm wheel 63. The vertical shaft 4 then drives the top plate 2 to rotate by a specified angle through the linkage assembly 5 at the top. Then, the pressure plate 83 is lowered by turning the screw 82 to press and fix the horizontal shaft 61. When the grinding wheel machine vibrates during operation, the spring 32 provides support, while the friction between the round tube 31 and the support rod 33 and the buffer sponge 7 can weaken the vibration effect and play a shock absorption role.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
