Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically a drill bit and end mill composite grinding machine. Background Technology

[0002] A tool sharpening machine is a device used to dress cutting tools, primarily high-speed steel metal cutting tools, and partially for dressing tools made of cemented carbide and other superhard materials, such as drill bits and end mills used in the CNC industry. Currently, existing tool sharpening machines, when sharpening drill bits and end mills, lack a structure to collect the dust generated during sharpening. This allows the dust to spread with the movement of personnel and the wind, hindering subsequent cleaning. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a composite grinding machine for drill bits and end mills, which solves the problem that existing grinding machines, when grinding drill bits and end mills, do not have a structure to collect the dust generated during grinding, so the dust spreads to the surrounding area with the movement of personnel and the wind.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a drill bit and milling cutter composite grinding machine, comprising a worktable and a pair of legs fixedly connected to its bottom end, a grinding machine mounted on the top of the worktable, a first mesh plate fixedly connected inside the worktable, an air collection hood fitted to the bottom of the first mesh plate, a housing fixedly connected between the worktable and one of the legs, and a first pipe connecting the housing and the air collection hood, an air suction mechanism mounted on the outer wall of the legs, and a fixing mechanism mounted on the top of the worktable.

[0005] Preferably, the air intake mechanism includes a fan fixedly connected to the outer wall of one of the support legs. The exhaust port and the air intake port of the fan are respectively connected to a second pipe and a third pipe. The third pipe passes through the adjacent support leg and connects to the inside of the housing. A second mesh plate is fixedly connected to the middle of the inside of the housing. A filter layer is snapped into the slot of the housing. A cleaning component is installed at the bottom of the second mesh plate.

[0006] Preferably, the cleaning assembly includes a first screw rotatably connected to the housing via a bearing, a cleaning brush plate is threadedly connected to the outer wall of the screw, and the top and front and rear ends of the cleaning brush plate are respectively attached to the second mesh plate and the inner wall of the housing, and a first handle is fixedly connected to one end of the first screw extending out of the housing.

[0010] Beneficial effects

[0011] This utility model provides a combined grinding machine for drill bits and end mills, which has the following beneficial effects:

[0012] The sharpening machine can be placed on the worktable, and then the second handle is turned. The second handle drives the second screw to rotate, and the second screw can move through the horizontal plate. In conjunction with the sliding groove of the vertical plate, it can drive the pressure plate to move, thereby fixing the sharpening machine on the worktable. Then, the external power supply and control circuit of each electrical structure are connected. When the sharpening machine is used to sharpen the drill bit and end mill, the fan can be turned on. The fan can draw air from the inside of the box through the third pipe, so that the air collection hood will generate suction. The dust generated by the sharpening machine when sharpening the drill bit and end mill will be sucked into the air collection hood through the first screen plate, and then discharged into the box through the first pipe. After that, the dust and air will pass through the second screen plate and the filter layer for filtration and interception. The air will be discharged through the third pipe, the fan and the second pipe, thus realizing the collection of sharpening dust.

[0013] After the device has been used for a period of time, the first handle can be turned to drive the first screw to rotate. The first screw, in conjunction with the housing, drives the cleaning brush plate to move. The cleaning brush plate cleans the dust intercepted on the second screen plate. After that, the housing plate can be disassembled, the dust swept out, and the filter layer replaced. This facilitates subsequent cleaning work. Attached Figure Description

[0030] It is worth noting that the electrical structures and other components involved in this application can be selected according to the user's needs, as long as they meet the requirements of this application. At the same time, the corresponding control circuits and other components are all existing technologies, which can be fully implemented by those skilled in the art, so they will not be described in detail here.

[0031] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0032] Example: When this device is needed, the sharpening machine 3 can be placed on the workbench 1, and the second handle 20 can be turned. The second screw 19 can be rotated by the second handle 20. The second screw 19 can be moved by the horizontal plate 18, and the pressure plate 21 can be moved by the sliding groove of the vertical plate 17. This fixes the sharpening machine 3 on the workbench 1. Then, the external power supply and control circuit of each electrical structure are connected. When the drill bit and end mill are sharpened by the sharpening machine 3, the fan 8 can be started. The fan 8 can draw air from the inside of the box 7 through the third pipe 10. This will generate suction at the air collection hood 5. The dust generated when the sharpening machine 3 sharpens the drill bit and end mill will be sucked into the air collection hood 5 through the first mesh plate 4, and then discharged into the box 7 through the first pipe 6. After that, the dust and air will be filtered and intercepted by the second mesh plate 11 and the filter layer 12 in sequence. The air will be discharged through the third pipe 10, the fan 8 and the second pipe 9. This achieves the collection of grinding dust.

[0033] After the device has been used for a period of time, the first handle 15 can be turned to drive the first screw 13 to rotate. The first screw 13, together with the housing 7, drives the cleaning brush 14 to move. The cleaning brush 14 cleans the dust intercepted on the second screen 11. Then the housing 16 can be disassembled to sweep out the dust and replace the filter layer 12. This facilitates subsequent cleaning work.
