Referring to fig. 1 to 4, a preferred embodiment of the present application provides an automatic adjustable dressing device 100 for a bearing outer race raceway grinding wheel, the device 100 at least comprising: base 1, coupling assembling 2, finishing assembly 3 and adjustment assembly 4. The connecting assembly 2 serves as a connecting structure of the device 100 for connecting the base 1 with other structures. The connecting assembly 2 includes a pair of connecting members 21 respectively installed at both sides of the base 1. The dressing assembly 3 is connected to the connecting assembly 2 for dressing the grinding wheel 110. The dressing component 3 comprises a rotary oil cylinder 31, a synchronous pulley module 32 connected with the output end of the rotary oil cylinder 31 and a diamond pen 36 connected with the synchronous pulley module 32, wherein the diamond pen 36 is abutted against the grinding wheel so as to conveniently dress the grinding wheel. When the rotary cylinder 31 rotates, the diamond pen 36 is driven to rotate by the synchronous pulley module 32 connected to the rotary cylinder 31 to dress the grinding wheel 110. An adjustment assembly 4 is connected to the dressing assembly 3 for adjusting the dressing curvature. The adjusting assembly 4 includes a calibration knob 41, an adjusting rod 42 connected to the calibration knob 41, and an elastic member set 43 connected to the adjusting rod 42, wherein the elastic member set 43 is connected to the diamond pen 36, and when the calibration knob 41 is rotated, the adjusting rod 42 is matched with the elastic member set 43 to drive the diamond pen 36 to move back and forth, so that the diamond pen 36 and the grinding wheel 110 are always supported. The device 100 enables the rotation to be more stable and not easy to damage through the rotating oil cylinder 31 and the synchronous pulley module 32, the curvature is adjusted and maintained through the scale knob 41, the adjustment is convenient, and the precision is controllable.
The working process of the dressing assembly 3 is as follows: the rotating cylinder 31 is started to drive the synchronous belt wheel module 32 to rotate, thereby driving the diamond pen 36 to rotate. Specifically, the trimming assembly 3 further includes a rotating housing 34, the rotating housing 34 is sleeved outside the adjusting rod 42 and connected to the synchronous pulley module 32, the synchronous pulley module 32 includes two synchronous pulleys 321 and a synchronous belt 322 respectively connected to the two synchronous pulleys 321, one of the synchronous pulleys 321 is connected to the output end of the rotating cylinder 31, and the other synchronous pulley 321 is connected to the rotating housing 34. When the rotary cylinder 31 is started, the output end of the rotary cylinder 31 drives one synchronous pulley 321 to rotate, and the synchronous belt 322 connected with the synchronous pulley 321 transmits the rotating force to the other synchronous pulley 321, so as to drive the rotary housing 34 to rotate, and finally, drive the diamond pen 36 to rotate.
The dressing member 3 includes a supporting base 33 for supporting the rotating cylinder 31 and the timing pulley module 32, in addition to the rotating cylinder 31 for providing the rotating force, the timing pulley module 32 for transmitting the rotating force, and the diamond pen 36 for dressing the grinding wheel 110, and the supporting base 33 is connected to the connecting member 2. The supporting base 33 has an extending portion 331, and the extending portion 331 is connected to the adjusting member 4 for supporting the adjusting member 4.
After the dressing assembly 3 dresses the grinding wheel 110, a gap may be generated between the diamond pen 36 and the grinding wheel 110, and therefore, the adjusting assembly 4 needs to be used to adjust the dressing curvature, so that the diamond pen 36 and the grinding wheel 110 continuously abut against each other, and the diamond pen 36 is convenient to continue dressing the grinding wheel 110. In order to clearly know the adjustment amount and improve the accuracy, in one embodiment, the dial knob 41 includes a dial 411 and a rotary member 412 disposed directly above the dial 411, scale marks are disposed around the dial 411, and a scale pointer 4121 is disposed on the rotary member 412, so that when the rotary member 412 is rotated, the scale pointer 4121 rotates around the dial 411, that is, the scale pointer 4121 rotates around the scale marks, and thus, the adjustment amount can be precisely controlled according to the scale marks.
The process of adjusting the trimming curvature by the adjusting assembly 4 is as follows: when the dial knob 41 is rotated, the adjusting rod 42 moves downward or upward along with the rotation of the dial knob 41, and at this time, the elastic member set 43 also moves back and forth due to the up-and-down movement of the adjusting rod 42, so as to adjust the position of the diamond pen 36. The elastic member group 43 includes two spring pieces 431, two fixed side plates (not shown) perpendicular to the spring pieces 431, and a supporting bottom plate 432, the two spring pieces 431, the two fixed side plates, and the supporting bottom plate 432 enclose a movable cavity (not shown) having a notch at the top, and the adjusting rod 42 moves up and down in the movable cavity from the notch to move the diamond pen 36 in the a direction or the b direction (as shown in fig. 4). Specifically, the supporting bottom plate 432 is provided with a pressing groove (not shown) having an inverted truncated cone shape with a wide top and a narrow bottom, the bottom of the adjusting rod 42 is provided with a pressing portion (not shown) having an inverted truncated cone shape with a wide top and a narrow bottom, the outer diameter of the bottom end of the pressing groove is smaller than the outer diameter of the top end of the pressing portion, and when the adjusting rod 42 moves up and down, that is, when the adjusting assembly 4 works, the inner walls of the pressing portion and the pressing groove are always pressed. Further, the inner walls of the pressing portions and the pressing grooves in the same direction as the spring piece 431 are pressed against each other. Illustratively, when the adjusting rod 42 moves downward, the pressing portion applies pressure to the inner wall of the pressing groove in the same direction as the spring piece 431, and at this time, the spring piece 431 is deformed by the pressure, and further, the position of the diamond pen 36 connected to the spring piece 431 is changed.
The dressing member 3 and the adjusting member 4 are rotatable with respect to the base 1, and when the grinding wheel 110 is not required to be dressed, the dressing member 3 and the adjusting member 4 can be rotated upward to reduce the size of the device 100 and occupy less space, and when the device is used again next time, the dressing member 3 and the adjusting member 4 can be rotated downward. Alternatively, the conditioning assembly 3 and the adjusting assembly 4 are rotated down mechanically. Specifically, the device 100 further comprises a pushing assembly 5, the pushing assembly 5 comprises a supporting frame 51 and a pushing member 52 installed on the supporting frame 51, the supporting frame 51 is fixed on the base 1, and the pushing member 52 pushes the trimming assembly 3 and the adjusting assembly 4 to move.
