DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 As shown, a blade grinding machine includes a grinding machine workbench 1, a driving motor 2, a fixture 3 and a grinding wheel 4. The driving motor 2 and the fixture 3 are both arranged above the grinding machine workbench 1, and the position of the driving motor 2 corresponds to the position of the grinding wheel 4, and the grinding wheel 4 is arranged at the end of the driving motor 2. A lifting platform for adjusting the height is installed between the driving motor 2 and the grinding machine workbench 1, and the driving motor 2 can be lifted and lowered in the vertical direction, and the fixture 3 can adjust the position in the front, back, left and right directions, and can also adjust the angle, so that the machine tool tool or blade at the fixture 3 can be clamped, and the tool or blade can also be manually picked up for grinding. A shielding structure 5 is arranged at the end of the driving motor 2 and located outside the grinding wheel 4, and the shielding structure 5 includes a fixed Plate 51, the fixed plate 51 is arranged at the end of the driving motor 2, the end of the driving motor 2 does not contact the middle of the fixed plate 51, and a baffle structure 52 is integrally provided at the edge of the fixed plate 51. The baffle structure 52 can cover the baffle structure 52 on the outside of the grinding wheel 4 to prevent sparks from splashing to the front when grinding the tool or blade, and the position of the baffle structure 52 can also be adjusted according to the surrounding environment of the grinder. Two rotating grooves 53 are provided on the surface of the fixed plate 51, and the inside of the two rotating grooves 53 are connected with fastening nuts 54, and the end of the fastening nut 54 is screwed with the driving motor 2. When it is necessary to prevent sparks from splashing to one place, the position of the baffle structure 52 can be rotated, and the baffle structure 52 can be used to block the sparks to prevent them from splashing onto clothes or skin.

[0022] In this embodiment, there is a gap between the baffle structure 52 and the edge of the clamp 3, the two rotating grooves 53 are arc-shaped, and the center of the arc of the rotating groove 53 coincides with the end of the driving motor 2. The rotation of the grinding wheel 4 will not affect the relative rotation of the fixed plate 51 and the baffle structure 52, so that manual grinding will not be affected.

[0023] In this embodiment, the surface of the fixed plate 51 is rotatably connected to the end of the driving motor 2, and the rotation angle range of the fixed plate 51 is 0-180°. During grinding, the position of the baffle structure 52 can be changed according to the need to manually adjust the blade.

[0024] In this embodiment, a protective structure 6 is provided at the edge of the baffle structure 52 and located outside the grinding wheel 4. The protective structure 6 includes two matching grooves 61. The matching grooves 61 are opened at the two side edges of the baffle structure 52. A movable ring 62 is slidably connected between the two matching grooves 61. The movable ring 62 is located outside the grinding wheel 4. The movable ring 62 slides along the inside of the matching groove 61 and will not affect the normal operation of the drive motor 2. A rotating stud 63 and a movable block 64 are provided inside the matching groove 61. The end of the rotating stud 63 is rotatably connected to the baffle structure 52. The rotating stud 63 is threadedly connected to the movable block 64. Rotating the rotating stud 63 can make the rotating stud 63 and the movable block 64 transmit to each other, so that the position of the movable block 64 changes, thereby limiting the moving position of the movable ring 62. A telescopic spring 65 is sleeved on the outside of the rotating stud 63 and located on one side of the movable ring 62. The telescopic spring 65 can be used to push the two ends of the movable ring 62, so that the movable ring 62 is always attached to the movable block 64.

[0025] In this embodiment, the two ends of the movable ring 62, the interior of the matching groove 61 and the movable block 64 are all T-shaped and cooperate with each other. The movable block 64 is slidably connected to the interior of the matching groove 61, and the two ends of the movable ring 62 are movably connected to the rotating stud 63. By adjusting the position of the movable ring 62, the staff can place their hands on the movable ring 62 to provide a fulcrum when manually grinding the machine tool blade, avoiding contact with the grinding wheel 4 due to large hand movements.

[0026] When the utility model is in use, the tool or blade of the machine tool that has been worn is manually polished. The staff holds the tool or blade in their hands and starts the drive motor 2 to drive the grinding wheel 4 to rotate, so that the grinding wheel 4 can polish the tool or blade. The angle or contact position of the blade can be changed according to the need for blade polishing, so that the blade can be polished to the required degree of use. During the contact between the grinding wheel 4 and the blade, the blade will contact the grinding wheel 4 to generate sparks, and the sparks are easy to splash onto the clothes or skin of people around the grinder, causing damage to the clothes or burns to the skin. At this time, protection can be provided by the shielding structure 5. Specifically, due to the different positions of the blade, the positions where the sparks splash out are also different. During polishing, the positions of the fixed plate 51 and the baffle structure 52 can be adjusted so that the fixed plate 51 and the baffle structure 52 can be rotated to the appropriate positions. At this time, the fixing plate 51 and the baffle structure 52 can be used to block the flying sparks, and the fixing plate 51 can also be rotated around the two fastening nuts 54, and then the fastening nuts 54 can be tightened, so that the fixing plate 51 and the baffle structure 52 can be firmly fixed, and the baffle structure 52 can be fixed in one position without changing. When manually grinding the blade, it is easy to cause the finger to contact the grinding wheel 4 due to the need to change the position of the blade at all times, which may cause danger. At this time, the protective structure 6 can be used for protection. Specifically, when holding the blade, the finger can be placed on the movable ring 62, so that the movable ring 62 slides along the rotating stud 63 and the matching groove 61, and can be moved to a certain position as needed. At this time, there will be a fulcrum when grinding the blade, avoiding the finger from moving too much and contacting the grinding wheel 4 due to the lack of a fulcrum when grinding the blade. The blade can also be clamped by the clamp 3 for grinding.

[0027] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
