Abstract
Description
Technical Field
[0001] The utility model relates to a special processing grinder for curved-edge drills. Background Art
[0002] As a type of drill with better cutting performance, the curved edge drill has a plurality of curved edges on its front cutting face. The grooved front cutting face can give the twist drill better comprehensive cutting performance.
[0003] However, there is currently no targeted processing equipment that can process zigzag-edged twist drills more accurately. Especially for industrialization, a dedicated grinder can effectively improve processing efficiency and thus reduce processing costs.
[0004] At present, the processing methods that have been tried include machining with machining center machine tools, such as the Tuowa machining center machine tool. During processing, due to the low rotation speed of the grinding head and the rapid wear of the grinding wheel, it is difficult to ensure the shape of the curved blade. The Luoxi machining center machine tool was used and the high-speed grinding head was replaced for experimentation, but the processed curved blade was too short and still could not meet the demand, and the processing cost was high.
[0005] The main reason for the above situation is that the blank is a fully ground drill bit. During the processing, if there is no special positioning device to position the spiral groove in a targeted manner, the curved blade shape on the front cutting edge cannot be well maintained. Utility Model Content
[0006] The utility model aims to provide a special processing grinder for a curved edge drill, which solves the problem of fixing the curved edge drill during the processing by adding a positioning device.
[0007] To achieve the above-mentioned purpose, the specific technical scheme of a special processing grinder for curved edge drills of the utility model is as follows: it includes a guide sleeve located in the center, the guide sleeve is used to preliminarily clamp the curved edge drill to be processed, a left push rod and a right push rod are respectively provided on both sides of the guide sleeve, a positioning device is provided on the right side of the guide sleeve, the positioning device includes a positioning ball matching the spiral groove structure on the curved edge drill, the positioning ball is installed on the frame through a telescopic structure, a forming grinding head is provided on the right side of the positioning device, and the forming grinding head is used to process the curved edge on the curved edge drill.
[0008] Furthermore, the curved blade drill to be processed is provided with a plurality of curved blade structures to be processed.
[0009] Beneficial effect: During the processing, a special positioning device can be used to position the spiral groove in a targeted manner. The positioning device can maintain a good fixing effect on the curved edge drill, so that the shape of the curved edge drill is more stable in the subsequent processing process and the yield rate is higher.

[0014] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a special processing grinder for curved edge drills of the utility model in conjunction with the accompanying drawings.
[0015] Implementation example:
[0016] like Figure 1-3 A special processing grinder for a curved-edge drill 5 is shown, comprising a guide sleeve 1 located in the center, the guide sleeve 1 is used for preliminarily clamping the curved-edge drill 5 to be processed, a left push rod 2 and a right push rod 3 are respectively provided on both sides of the guide sleeve 1, a positioning device 4 is provided on the right side of the guide sleeve 1, the positioning device 4 comprises a positioning ball 6 matched with the spiral groove structure on the curved-edge drill 5, the positioning ball 6 is installed on the frame through a telescopic structure, a forming grinding head is provided on the right side of the positioning device 4, the forming grinding head is used for processing the curved edge on the curved-edge drill 5, and the curved-edge drill 5 to be processed is provided with a plurality of curved-edge structures 8 to be processed.
[0017] Specific processing process:
[0018] 1. The curved drill 5 is fed into the guide sleeve 1 through the right push rod 3. When the curved drill 5 moves to the left, the positioning device 4 is pressed downward into the spiral groove of the curved drill 5 at the same time.
[0019] 2. The left push rod 2 pushes the workpiece to the right, and under the pressure of the positioning device 4, the surface processed by the curved drill 5 remains fixed.
[0020] 3. The profiled grinding head 7 starts to process the curved drill 5.
[0021] 4. After processing a curved drill 5, the positioning device 4 is lifted up, and the right push rod 3 pushes the processed curved drill 5 to the left. At the same time, the left push rod 2 leaves the central axis of the right push rod 3, so that the processed curved drill 5 can be pushed out from the left. At the same time, the right push rod 3 also pushes out another curved drill 5 to be processed. At this time, the positioning device 4 falls, and the time difference is used to press the positioning device 4 into the spiral groove of the next curved drill 5 to be processed, and the above steps 1, 2 and 3 are repeated.
[0022] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
