Specific implementation method:

[0030] The present invention is further described below with specific embodiments:

[0031] like Figure 1-9 As shown, the utility model provides a double-sided grinder, which includes a bed 1, on which a first grinding mechanism and a second grinding mechanism are arranged, the first grinding mechanism and the second grinding mechanism both include a grinding wheel 2 rotating around their own axis, a grinding space is formed between the two grinding wheels 2, the first grinding mechanism or / and the second grinding mechanism can move laterally to adjust the size of the grinding space, a feeding mechanism for driving the workpiece to move is arranged in the grinding space, the feeding mechanism includes a first driving mechanism and a lower feeding carriage 4 driven by the first driving mechanism to reciprocate longitudinally, a workpiece platform 5 is arranged on the lower feeding carriage 4 through an adjusting mechanism, the lateral position of the workpiece platform 5 is adjusted by the adjusting mechanism, a plurality of mounting holes for mounting a clamp body 3 are arranged on the workpiece platform 5 along the longitudinal direction, the clamp body 3 is arranged on the workpiece platform 5, the first grinding mechanism or / and the second grinding mechanism are driven by the second driving mechanism to move laterally.

[0032] like Figure 1 and Figure 3 As shown, the clamp body 3 of the utility model is fixed in the mounting hole by screwing, and can process different workpieces, thereby improving versatility. In addition, the distance between the two grinding wheels 2 can be adjusted by the second driving mechanism, which is also suitable for processing workpieces of different thicknesses, and the adjustment mechanism can cooperate to initially adjust the workpiece to the center position of the grinding space.

[0033] Generally speaking, the second driving mechanism preferably adopts a screw transmission mechanism, but a gear transmission mechanism, a chain transmission mechanism, etc. may also be applicable.

[0034] Further, if Figure 3-5As shown, a longitudinal feed slide 6 is arranged on the upper plane of the lower feed slide 4, an upper feed slide 7 is arranged on the longitudinal feed slide 6 via an adjusting mechanism, and the workpiece platform 5 is fixed on the upper feed slide 7 via fasteners.

[0035] As can be seen from the above, the adjustment mechanism of the utility model can roughly adjust the position of the workpiece platform 5. To this end, the utility model is also provided with a mechanism for finely adjusting the position of the workpiece platform 5, specifically: an adjustment plate 8 is provided at one end of the workpiece platform 5, and two adjustment screws 9 are relatively screwed on the adjustment plate 8, and the two adjustment screws 9 are respectively abutted on the longitudinal feed lower slide 6 to finely adjust the lateral position of the workpiece platform 5. In order to further control the accuracy, a dial indicator guide block 10 is provided at one end of the longitudinal feed lower slide 6, and a dial indicator 11 is provided on the dial indicator guide block 10 through a meter frame 12, and the meter frame 12 can adjust the position laterally along the dial indicator guide block 10, and one end of the indicator plate 13 is provided on the adjustment plate 8, and the other end extends to the top of the dial indicator guide block 10 and abuts against the dial indicator 11. The position of fine adjustment is controlled by the dial indicator 11, and the adjustment accuracy is high.

[0036] Assuming that the lateral position is a left-right position, the two adjusting screws 9 can drive the workpiece platform 5 to move leftward or rightward respectively.

[0037] It should be noted that if Figure 5 As shown, the adjustment mechanism includes a feed pressure plate 14, a transversely arranged first screw rod 15 and a screw rod seat 16 fixed on the longitudinal feed lower slide 6, vertical plates 17 are arranged at both ends of the feed pressure plate 14, and both ends of the first screw rod 15 extend out of the vertical plates 17 respectively, a nut 18 is arranged at one end of the first screw rod 15, and a screw rod handwheel 19 is arranged at the other end.

[0038] Of course, the screw hand wheel 19 of the utility model can also be replaced by a motor to achieve automatic adjustment, and the action of the motor is controlled by the control system.

[0039] When the lateral position of the workpiece platform 5 needs to be adjusted, the first screw 15 is driven to rotate by the screw handwheel 19, thereby driving the longitudinal feed lower slide 6, the upper feed carriage 7 and the workpiece platform 5 to move.

[0040] Since the above implementation adopts manual adjustment, it needs to be fixed after the adjustment is completed to prevent displacement due to external force during the processing, which affects the processing accuracy. Figure 1-6If so, the utility model is provided with horizontal extension plates 20 on both sides of the feed platen 14, and strip holes 21 are provided on the horizontal extension plates 20 in the transverse direction. The locking screw 22 passes through the strip holes 21 and is screwed on the longitudinal feed lower seat 6. The upper end of the locking screw 22 is provided with a clamping member 23 that locks the feed carriage 14 and the longitudinal feed lower seat 6. When adjustment is required, the clamping member 23 is opened to make the horizontal extension plate 20 of the feed platen 14 and the longitudinal feed lower seat 6 in a free state. After the adjustment is completed, the clamping member 23 is locked to fix the horizontal extension plate 20 and the longitudinal feed lower seat 6.

[0041] In order to make the workpiece platform 5 smoothly adjusted, first linear guide sliders 24 are respectively arranged in the transverse direction at both ends of the longitudinal feed lower slide 6, and first linear guides 25 are respectively arranged in the transverse direction at both ends of the bottom surface of the workpiece platform 5, and the workpiece platform 5 is slidably connected through the first linear guides 25 and the first linear guide sliders 24. The first linear guide sliders 24 are fixed on the longitudinal feed lower slide 6 by screws, and the first linear guides 25 are fixed on the bottom surface of the upper feed carriage 7 by screws.

[0042] Since the utility model is used to grind the end face of a workpiece, in the actual processing process, such as Figure 2 , Figure 7 , Figure 8 As shown, the outer cylindrical surface 26 of the grinding wheel 2 and the angle 27 between the side surfaces adjacent to the workpiece are easy to wear, so the grinding wheel 2 needs to be trimmed after a period of use. For this reason, the utility model is provided with a grinding wheel dresser 28 at the rear end of the lower feed carriage 4 through a third driving mechanism, and the third driving mechanism drives the grinding wheel dresser 28 to reciprocate in the lateral direction. The third driving mechanism can adjust the position of the grinding wheel dresser 28 to trim the two grinding wheels 2 respectively.

[0043] It should be noted that the third driving mechanism here usually adopts a screw drive structure. The third driving mechanism is fixed on the lower feeding carriage 4 through a trimmer pad 29 .

[0044] Specifically, if Figure 2 and Figure 8 As shown, the grinding wheel dresser 28 is L-shaped, including a horizontal portion and a vertical portion. A longitudinally arranged convex strip is provided on the bottom surface of the horizontal portion, and a longitudinally arranged strip groove is provided on the dresser bottom plate 29. The convex strip is arranged in the strip groove to facilitate the adjustment of the longitudinal position of the grinding wheel dresser 28.

[0045] The grinding process of the two grinding wheels 2 of the utility model is as follows:

[0046] First, one of the grinding wheels is moved laterally in a direction away from the grinding wheel dresser 28, and the grinding wheel dresser 28 dresses the front side of the grinding wheel that has not moved;

[0047] Then the third driving mechanism drives the grinding wheel dresser 28 to move a distance toward the moving grinding wheel, and the moving grinding wheel also moves to the direction where the grinding wheel dresser 28 is located, and the grinding wheel dresser 28 dresses the front side of the moving grinding wheel;

[0048] The last moving grinding wheel continues to move toward the direction of the non-moving grinding wheel until the distance between the two grinding wheels 2 is the width of the workpiece. At the same time, the grinding wheel dresser 28 also moves to the corresponding position. At this time, the grinding wheel dresser 28 grinds the outer cylindrical surfaces 26 of the two grinding wheels 2 at the same time.

[0049] At this point, the dressing work of the grinding wheel 2 is completed.

[0050] In addition, if Figure 1 , Figure 2 and Fig. 9 As shown, the bed 1 of the utility model uses an artificial marble bed, and a first boss 30, a second boss 31 for installing a first grinding mechanism and a second grinding mechanism, and a third boss 32 for installing a feeding mechanism are arranged on the bed 1, and an inclined guide groove 33 for sewage discharge is formed below the first boss 30, the second boss 31 and the third boss 32, and the high end of the inclined guide groove 33 is located below the first boss 30, and the low end passes through the side wall of the bed 1 close to the second boss 31, and a collection box 34 is arranged on the side wall, and a plurality of embedded parts are embedded in the first boss 30, the second boss 31 and the third boss 32, which increases the machinability of the bed 1, and threaded holes are arranged in the embedded parts to facilitate the installation of the first grinding mechanism, the second grinding mechanism and the feeding mechanism.

[0051] It should be noted that if Figure 3 and Figure 4 As shown, the first driving mechanism of the utility model is a screw transmission mechanism, including a base plate 35, a screw nut seat fixed on the base plate 35, a second screw connected to the screw nut seat, the second screw driven to rotate by a motor 36, a second linear guide rail is provided on the bottom surface of the feed carriage 4, a second linear guide rail slider is provided on the base plate 35, and the second linear guide rail is slidably connected to the second linear guide rail slider. The base plate 35 is fixed on the third boss 32 by screws.

[0052] It is worth noting that Figure 1 and Figure 2 As shown, the first grinding mechanism of this embodiment is driven by the fourth driving mechanism to move in the lateral direction. The fourth driving mechanism also adopts a screw transmission mechanism. The fourth driving mechanism is fixed on the first cushion block 36, and the first cushion block 36 is fixed on the first boss 30 by screws. The second grinding mechanism is a fixed structure, and the second grinding mechanism is fixed on the second boss 31 by the second cushion block 37 and screws.

[0053] The above embodiment is only one of the preferred embodiments of the present invention, and is not intended to limit the scope of implementation of the present invention.
