[0002] A surface grinder is a type of grinder that mainly uses a grinding wheel to rotate and grind workpieces to achieve the required flatness. According to the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of a rectangular worktable surface grinder are the width and length of the worktable, and the main parameter of a circular worktable is the diameter of the worktable surface. According to the type of shaft, it can be divided into horizontal shaft and vertical shaft grinders.

[0003] In the prior art, some grinders are not equipped with protective measures during grinding, and the metal debris generated by grinding flies everywhere, easily injuring the staff. Some grinders are equipped with protective measures, but the position of the protective plates is mostly fixed, which partially interferes with operations such as workpiece clamping and inspection, making it inconvenient for the staff to observe the workpiece in real time. Utility Model Content

[0005] Preferably, the protective device includes a fixed seat, the inner surface of the fixed seat is fixedly connected to the motor, the output end of the motor is rotatably connected to the active bevel gear, the outer surface of the active bevel gear is meshed with the driven bevel gear, the outer surface of the driven bevel gear is fixedly connected to a long screw, the outer surface of the long screw is meshed with a sliding block, the outer surface of the sliding block is fixedly connected to a blocking box, the inner surface of the blocking box is slidably connected with a baffle, the upper surface of the fixed seat is fixedly connected to the lower surface of the fixed plate, the outer surface of the long screw is rotatably connected to the inner surface of the fixed seat, the outer surface of the blocking box is slidably connected to the inner surface of the fixed plate, the outer surface of the baffle is fixedly connected to the inner surface of the fixed plate, the up and down movement of the sliding block will drive the blocking box, so that the workpiece will rise during the grinding process, and the blocking box will block sparks and debris.

[0006] Preferably, the clamping device includes a fixed shaft, the inner surface of the fixed shaft is fixedly connected to a short screw rod, the outer surface of the short screw rod is meshed with a clamping plate, the upper surface of the short screw rod is rotatably connected to a fixed block, the lower surface of the fixed block is fixedly connected to a sliding column, the outer surface of the sliding column is fixedly connected to the inner surface of the fixed plate, the inner surface of the clamping plate is slidably connected to the outer surface of the sliding column, the outer surface of the fixed shaft is rotatably connected to the inner surface of the fixed plate, and the lower surface of the fixed shaft is fixedly connected to the upper surface of the long screw rod, thereby achieving the purpose of clamping the workpiece when the protective device is raised.

[0007] The beneficial effects of the utility model are as follows:

[0008] 1. The utility model sets a protective device. During the process of grinding the object by controlling the grinding wheel on the base, the grinding wheel moves on the movable rail, so the position of the workpiece only needs to be fixed. When grinding starts, the motor is turned on synchronously, and the rotation of the motor drives the active bevel gear to rotate, and the active bevel gear drives the driven bevel gear to rotate. Since the long lead screw is fixed on the driven bevel gear, the rotating driven bevel gear will rotate synchronously with the long lead screw, so that the slider moves on the long lead screw, and the up and down movement of the slider will drive the blocking box, so that the workpiece will rise during the grinding process. The blocking box blocks sparks and debris, and the blocking box and the baffle plate cooperate to collect the debris in the blocking box, and the descending blocking box will be blocked by the fixed seat. The upper surface of the blocking box that blocks the movement is flush with the upper surface of the fixed plate at this time, which is convenient for removing the workpiece.

[0009] 2. The utility model sets a clamping device. During the rotation of the long screw, the long screw drives the fixed shaft to rotate. At this time, the short screw fixedly connected to the fixed shaft rotates accordingly, and the rotating short screw drives the clamping plate to move. Since the spiral direction of the short screw is opposite to that of the long screw, and the pitch of the short screw is smaller than that of the long screw, the clamping plate will synchronously drop when the blocking box is raised after the motor is started to clamp the workpiece on the workbench. The sliding column limits the moving direction of the clamping plate, and the fixed block limits the displacement height of the clamping plate, thereby achieving the purpose of clamping the workpiece when the protective device is raised and increasing the stability of the workpiece.

Since the long screw rod 65 is fixed on the driven bevel gear 64, the rotating driven bevel gear 64 will rotate synchronously with the long screw rod 65, so that the slider 66 moves on the long screw rod 65, and the up and down movement of the slider 66 will drive the blocking box 67, so that the workpiece will rise during the grinding process. The blocking box 67 blocks sparks and debris, and the blocking box 67 and the baffle 68 cooperate to collect the debris in the blocking box 67.

[0018] The clamping device 7 includes a fixed shaft 71, the inner surface of the fixed shaft 71 is fixedly connected to a short screw rod 72, the outer surface of the short screw rod 72 is meshed with a clamping plate 73, the upper surface of the short screw rod 72 is rotatably connected to a fixed block 74, the lower surface of the fixed block 74 is fixedly connected to a sliding column 75, the outer surface of the sliding column 75 is fixedly connected to the inner surface of the fixed plate 5, the inner surface of the clamping plate 73 is slidably connected to the outer surface of the sliding column 75, the outer surface of the fixed shaft 71 is rotatably connected to the inner surface of the fixed plate 5, and the lower surface of the fixed shaft 71 is fixedly connected to the upper surface of the long screw rod 65.

[0019] Working principle:

[0020] When in use, a protective device 6 is set. During the process of controlling the grinding wheel 3 to grind the object on the base 1, the grinding wheel 3 moves on the movable rail 2, so the workpiece only needs to be fixed in position. When grinding starts, the motor 62 is turned on synchronously, and the rotation of the motor 62 drives the active bevel gear 63 to rotate, and the active bevel gear 63 drives the driven bevel gear 64 to rotate. Since the long screw rod 65 is fixed on the driven bevel gear 64, the rotating driven bevel gear 64 will rotate synchronously with the long screw rod 65, so that the slider 66 moves on the long screw rod 65, and the up and down movement of the slider 66 will drive the blocking box 67, so that the workpiece will rise during the grinding process.

At this time, the short screw rod 72 fixedly connected to the fixed shaft 71 rotates accordingly, and the rotating short screw rod 72 drives the clamping plate 73 to move. Since the spiral direction of the short screw rod 72 is opposite to the spiral direction of the long screw rod 65, and the pitch of the short screw rod 72 is smaller than that of the long screw rod 65, the clamping plate 73 drops synchronously when the blocking box 67 is raised after the motor 62 is started, so as to clamp the workpiece on the workbench 4. The sliding column 75 limits the moving direction of the clamping plate 73, and the fixed block 74 limits the displacement height of the clamping plate 73, thereby achieving the purpose of clamping the workpiece when the protective device 6 is raised.
