Technical Field

[0001] The invention relates to the technical field of quartz processing, and more specifically to a groove cutting machine sharpening tool and method and a groove cutting processing method. Background Art

[0002] In the processing of quartz products, the processing of grooves on the surface of quartz rods is often involved. The common processing method is to use a grinding wheel to grind the surface of the quartz rod to form grooves on the surface of the quartz rod. Since the shape of the grooves on the surface of the quartz rod often does not completely match the shape of the purchased grinding wheel, it is necessary to trim the grinding wheel to meet the grinding requirements. However, the conventional diamond grinding wheel has low grinding efficiency and cannot make overall corrections to the flatness of the tool. During the processing of the grooves on the surface of the quartz rod, the stability is poor, which affects the quality of the product. Summary of the invention

[0003] In order to overcome the above shortcomings, the present invention provides a groove cutting machine grinding tool and method and a groove cutting processing method, which can shorten the grinding and dressing time of the grinding wheel groove cutting knife, improve work efficiency, and can perform overall correction on the flatness of the grinding wheel groove cutting knife. During the groove processing of the quartz rod surface, the stability is good, which ensures the quality of the product.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solution: a groove cutting machine sharpening tool, including a support, the support is provided with a transverse mounting hole and a longitudinal mounting hole, and the transverse mounting hole and the longitudinal mounting hole are both fastened with a diamond pen.

[0005] When the groove cutting machine is used to process the grooves on the surface of the quartz rod, the grinding wheel groove cutter on the groove cutting machine contacts and grinds the surface of the quartz rod to process the grooves. Therefore, the outer edge contour of the grinding wheel groove cutter must match the groove. The grinding wheel groove cutter needs to be trimmed before groove cutting. During trimming, first move the side edge of the grinding wheel groove cutter toward the tip of the diamond pen connected to the horizontal mounting hole, and rotate the grinding wheel groove cutter to grind and trim the side edge. After that, the grinding wheel groove cutter moves so that the outer edge of the grinding wheel groove cutter is close to the tip of the diamond pen connected to the longitudinal mounting hole, and the grinding wheel groove cutter rotates to grind and trim the outer edge contour so that the outer edge contour of the grinding wheel groove cutter matches the groove processed on the quartz rod. The diamond pen connection is positioned on the support, and diamond pens are set in both the horizontal and vertical directions. The horizontal diamond pen performs side trimming to achieve the overall correction of the flatness of the grinding wheel groove cutter. The outer edge is trimmed with a longitudinal diamond pen so that the outer edge profile of the grinding wheel groove cutter matches the groove machined on the quartz rod, facilitating the precise machining of the groove.

[0006] The groove cutting machine grinding jig can shorten the grinding and dressing time of the grinding wheel groove cutting knife, improve work efficiency, and can make an overall correction to the flatness of the grinding wheel groove cutting knife.

[0007] Preferably, a base is provided at the lower end of the support, and a magnetic block is fastened to the base.

[0008] The entire jig is installed on the workbench of the groove cutting machine through the base, and the magnetic block can be attracted and positioned with the workbench, playing a positioning role in the process of fastening the base and the workbench.

[0009] Preferably, the support is a rectangular columnar structure, with transverse mounting holes disposed on both left and right sides of the support, and longitudinal mounting holes disposed on both front and rear sides of the support.

[0010] Diamond pens can be installed in four directions of the support, front, back, left, and right, which facilitates the dressing operation of the grinding wheel groove cutter.

[0011] Preferably, a locking screw is connected to the support, and the locking screw abuts against the diamond pen to fasten the diamond pen.

[0012] The diamond pen is fastened by a locking screw, which is stable and reliable.

[0013] Preferably, a cooling channel is provided in the diamond pen, and flow ring grooves are provided on the inner walls of the transverse mounting hole and the longitudinal mounting hole. One end of the cooling channel opens toward the tip of the diamond pen, and the other end of the cooling channel is connected to the flow ring groove. A liquid inlet nozzle connected to the flow ring groove is provided on the support.

[0014] During the contact grinding and dressing process between the grinding wheel groove cutter and the diamond pen tip, coolant is introduced into the liquid inlet nozzle. After passing through the cooling flow channel, the coolant is sprayed from the end of the cooling flow channel to the contact position between the grinding wheel groove cutter and the diamond pen tip, cooling the contact grinding position while washing away the grinding chips, which is beneficial to improving the grinding and dressing effect.

[0015] Preferably, a liquid outlet block is arranged at the opening of the cooling channel toward the tip of the diamond pen. The liquid outlet block can be detachably mounted on the diamond pen. An inclined liquid outlet hole is arranged on the liquid outlet block. The liquid outlet hole serves as a part of the cooling channel, and the opening of the liquid outlet hole faces the tip of the diamond pen.

[0016] The setting of the liquid outlet block facilitates the processing of the cooling channel. The inclined liquid outlet hole is set on the liquid outlet block. The liquid outlet block can be detachably installed on the diamond pen. The liquid outlet block with liquid outlet holes of different inclined angles can be selected and installed on the diamond pen, which is flexible and convenient.

[0018] When the grinding wheel groove cutter is being sharpened and trimmed, the grinding and trimming is achieved by rotating the grinding wheel groove cutter and contacting the diamond pen. First, the groove cutter sharpening jig is loaded onto the groove cutter, and then the grinding wheel groove cutter is moved so that the side edge of the grinding wheel groove cutter is close to the diamond pen tip connected to the horizontal mounting hole for grinding and trimming of the side edge. Then the outer edge of the grinding wheel groove cutter is close to the diamond pen tip connected to the longitudinal mounting hole for grinding and trimming of the outer edge contour so that the outer edge contour of the grinding wheel groove cutter matches the groove machined on the quartz rod. The corrected grinding wheel groove cutter can machine grooves on the quartz rod.

[0019] Preferably, during the processes of S2 and S3, coolant is sprayed on the contact grinding position between the grinding wheel groove cutter and the diamond pen.

[0020] Spraying coolant onto the contact grinding area can cool it and wash away the grinding chips at the same time, which is beneficial to improving the grinding and dressing effect.

[0022] When the quartz rod is grooved, the grinding wheel groove cutter is first trimmed to make the outer edge contour of the grinding wheel groove cutter match the shape of the groove to be processed on the quartz rod. When the quartz rod is grooved, the quartz rod is clamped on the positioning clamping mechanism to ensure the stability and reliability of the processing. After the grinding wheel groove cutter has been used for a period of time, it is trimmed again to ensure the matching degree between the outer contour of the grinding wheel groove cutter and the groove.

[0023] Preferably, the positioning and clamping mechanism includes a fixed seat and a movable seat, a clamping rod is arranged between the fixed seat and the movable seat, a plurality of positioning grooves are arranged at intervals on the fixed seat and the movable seat, the quartz rod is loaded on the positioning groove, and the movable seat moves close to the fixed seat to clamp the quartz rod; the clamping rod is connected to the rotating shaft, and the rotating shaft deflects to the left or to the right so that the clamping rod is pressed against the quartz rod.

[0024] Multiple quartz rods of the same specification are clamped between the fixed seat and the movable seat. The quartz rods are loaded on the positioning grooves. The movable seat moves on the workbench toward the fixed seat, so that the two ends of the quartz rod are clamped between the fixed seat and the movable seat, and then the clamping rod is used to clamp and position the rods. After the quartz rods are clamped and positioned, the grooves are processed to ensure the stability of the quartz rods. The rotating shaft is first deflected to the left to make the clamping rod press on the left half of the quartz rod. After the groove processing on the right half of the quartz rod is completed, the rotating shaft is deflected to the right to make the clamping rod press on the right half of the quartz rod, and the groove on the left half of the quartz rod is processed.
