Description

Technical Field

[0001] The utility model relates to a grinding machine technology, more specifically, it relates to a double-bevel grinding wheel grinding machine. Background Art

[0002] At present, in the slider grinding work, we will encounter the grinding of workpieces of various sizes and specifications. For large-sized sliders, due to their relatively large size and large grinding space range, the grinding operation is simple and the work efficiency is high. For micro sliders, due to their relatively small size, the grinding operation range is limited, the grinding is difficult and the work efficiency is low. A long groove is set on the micro slider. During the grinding operation, it is necessary to grind the two opposite side walls of the long groove. The traditional grinding method is to install a grinding head on the electric spindle, insert the grinding head into the long groove, grind one side wall of the long groove first, and then grind the other side wall after the grinding of one side wall is completed, which has low work efficiency. Moreover, due to the small width of the long groove, the diameter of the grinding head inserted into the long groove needs to be made small, resulting in a shorter contact arc length between the grinding head and the grinding surface, a smaller grinding linear speed, reduced grinding efficiency and grinding effect, and easy generation of grinding marks on the grinding surface. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the utility model provides a double-bevel grinding wheel grinder, which adopts a double grinding head oblique insertion setting. The two grinding heads grind the two side walls of the long groove on the micro slide rail at the same time, which greatly improves the grinding efficiency; the oblique insertion setting of the grinding head only requires inserting the lower edge of the grinding head into the long groove. The diameter of the grinding head is large, the contact arc with the grinding surface is long, and the linear speed of grinding is high, which can improve the grinding efficiency and grinding effect and avoid the generation of grinding marks.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a double-bevel grinding wheel grinder, comprising a machine body and a grinding unit installed on the machine body, a grinding head is arranged on the grinding unit, two grinding units are arranged at intervals, the grinding heads on the two grinding units are staggered along the X-axis, and the two grinding heads are tilted downward in the direction of approaching each other along the Y-axis to form two obliquely inserted grinding head structures; the lower edges of the two grinding heads realize the fitting grinding of the two side walls of the long groove on the micro slide rail.

[0005] When grinding the two side walls of the long groove of the micro slide, the two inclined grinding heads are respectively fitted with the two side walls of the long groove for grinding, and the two side walls of the long groove are ground at the same time, which greatly improves the work efficiency. In addition, the grinding head is inclined, and only the lower edge is inserted into the long groove, so the diameter of the grinding head can be made larger, the contact arc between the grinding head and the grinding surface is long, and the grinding linear speed is high, which can improve the grinding efficiency and grinding effect and avoid the generation of grinding lines. The grinding heads on the two grinding units are staggered along the X-axis to avoid interference during the movement of the grinding heads.

[0006] Preferably, a connecting beam is provided on the machine body, and the two grinding units are installed at intervals on the same side of the connecting beam.

[0007] The two grinding units are installed on the same side of the connecting beam, which can shorten the distance between the two grinding heads, thereby shortening the mutual moving distance between the micro slide rail and the grinding head during the grinding process, speeding up the grinding speed and improving work efficiency.

[0008] Preferably, the grinding unit comprises a cross slide, the cross slide is installed on the connecting beam for lifting and movement, and the grinding head is installed on the cross slide.

[0009] The setting of the cross slide realizes the movement of the grinding head in the Y and Z directions, while the micro slide moves in the X direction, thereby realizing movement in three directions during the grinding process. The two grinding heads do not need to move in the X direction to avoid interference between the two grinding heads.

[0010] Preferably, the cross slide includes a longitudinal plate and a transverse plate, a connecting end is arranged at the inner end of the transverse plate, the two connecting ends are staggered along the X-axis, and the two grinding heads are respectively mounted on the two connecting ends.

[0011] The longitudinal plate can move in the Z direction, the transverse plate can move in the Y direction, and the grinding head is installed on the connection end to realize the movement in the Y direction and the Z direction. The setting of the connection end facilitates the installation of the grinding head and the dislocation setting of the two grinding heads.

[0012] Preferably, the inner end of the transverse plate is connected to the baffle.

[0013] The baffle can block the wear chips, preventing the wear chips from entering the slide rail corresponding to the translation seat and affecting the sliding of the translation seat.

[0014] Preferably, a clamping base moving along the X-axis is installed on the machine body, and the micro slide rail is loaded on the clamping base for grinding.

[0015] The micro slide rail is loaded on the clamping base and positioned before the grinding operation is carried out. During grinding, the clamping base moves along the X-axis, so that the micro slide rail is ground along the length direction, which is convenient and reliable.

[0016] Preferably, a dresser is installed at one end of the clamping base, and the dresser includes a rotatably arranged dresser wheel, and the dresser wheel realizes grinding and dressing of the grinding head.

[0017] The dresser is used to perform the dressing operation on the grinding head to ensure the grinding effect.

[0018] Preferably, a diamond pen is installed on the machine body, and the diamond pen rotates to grind and trim the surface of the clamping base.

[0020] Preferably, a cabin is installed on the fuselage, the grinding unit is installed in the cabin, a window is provided in the cabin, and the grinding head grinds the micro slide rail in the cabin.

[0021] The cabin plays a protective role to avoid safety hazards.

[0023] Since two grinding units are arranged at intervals, grinding chips will remain in front of the micro slide after grinding is completed, and will remain on the side wall to be ground later. By setting the left flushing pipe and the right flushing pipe, the remaining grinding chips can be flushed away before grinding, thereby improving the grinding effect.

[0024] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model adopts a double grinding head oblique insertion setting, and the two grinding heads grind the two side walls of the long groove on the micro slide rail at the same time, which greatly improves the grinding efficiency; the oblique insertion setting of the grinding head only requires inserting the lower edge of the grinding head into the long groove, the grinding head has a large diameter, a long contact arc with the grinding surface, and a high grinding linear speed, which can improve the grinding efficiency and grinding effect and avoid the generation of grinding marks.

The left flushing pipe 26 sprays coolant on the side wall of the micro slide 4 toward the left side of the grinding head 3, and the right flushing pipe 27 sprays coolant on the side wall of the micro slide 4 toward the right side of the grinding head 3. When the micro-slide 4 moves to the right for grinding, the coolant sprayed from the right flushing pipe 27 flushes the side wall of the micro-slide 4 to be ground, preventing grinding chips from remaining on the side wall of the micro-slide 4 to be ground and affecting the grinding effect; the coolant sprayed from the right-left flushing pipe 26 flushes the side wall of the micro-slide 4 that has been ground to flush out the grinding chips.

[0050] Since two grinding units 2 are arranged at intervals, grinding chips will remain in front of the micro slide 4 after grinding and will remain on the side wall to be ground later. By setting the left flushing pipe 26 and the right flushing pipe 27, the remaining grinding chips can be flushed away before grinding, thereby improving the grinding effect.

[0051] When grinding the grooves on both side walls of the long groove on the micro slide 4, first select the grinding head 3 that matches the micro slide 4 and install it on the grinding unit 2, then install the micro slide 4 on the clamping base 19, the clamping base 19 fixes the micro slide 4 by magnetic attraction, and a positioning bar 20 is set on the clamping base 19, and the positioning bar 20 positions the side of the micro slide 4. The length direction of the micro slide 4 is parallel to the X-axis. Then start the grinding machine device, and the two grinding heads 3 move according to the parameters set by the system, so that the lower edges of the two grinding heads 3 are respectively inserted into the long groove, and the lower edges of the two grinding heads 3 grind the two side walls of the long groove respectively, and at the same time the clamping base 19 reciprocates along the X-axis; the grinding head 3 moves along the Y-axis and Z-axis to adjust the grinding feed amount. The two grinding heads 3 grind the two side walls of the long groove on the micro slide 4 at the same time, which greatly improves the grinding efficiency; the double grinding heads 3 are arranged obliquely, and only the lower edge of the grinding head 3 needs to be inserted into the long groove. Even if the diameter of the grinding head 3 is increased, it will not contact and interfere with the non-grinding surface on the micro slide 4. The large-diameter grinding head 3 has a long contact arc with the grinding surface, and the grinding linear speed is high, which can improve the grinding efficiency and grinding effect and avoid the generation of grinding marks.
