Description

Technical Field

[0001] The present invention relates to the technical field of resin grinding wheel processing, and specifically to a surface dressing device for resin grinding wheel processing. Background Technique

[0002] A resin grinding wheel is a grinding wheel made of resin, usually used on abrasive cutting equipment. After the resin grinding wheel is used for a certain period of time, residual chips will be embedded between the abrasive grains on the surface of the resin grinding wheel or the sharpness of the abrasive grains will decrease. It needs to be dressed. In the existing dressing methods, most are carried out by manually holding a dressing tool. When manually dressing the side of the resin grinding wheel, there is no fulcrum, the movement is uneven, resulting in intermittent dressing. Innumerable high and low points are formed on the side of the resin grinding wheel. When grinding with the workpiece, a net-like pattern is formed. Especially when the grinding area is large, the surface unevenness is increased; when dressing the circumferential surface of the resin grinding wheel, the moving speed of the diamond pen is not evenly controlled. If the moving speed is too fast, the unevenness of the cutting edge is high, and the abrasive grains will quickly fall off in a short time, making the resin grinding wheel blunt, and vibration marks will appear on the surface of the workpiece, forming a multi-prism. If the moving speed is too slow, within the unit area, the abrasive grains are flat and uniform, but the resistance during grinding is increased, and the grinding heat is generated too quickly, which is likely to burn or crack the surface of the workpiece, and it is also easy to cause the roundness of the workpiece to exceed the tolerance.

DETAILED DESCRIPTION OF THE INVENTION

[0033] Referring to Figures 1-6 , the present invention provides a technical solution: a surface dressing device for resin grinding wheel processing, which includes:

[0034] A suitcase 6, with a fixing base one 1 installed inside it. A mounting shaft 2 is rotatably installed on the fixing base one 1. A rotating wheel two 56 is fixedly sleeved on the mounting shaft 2. The rotating wheel two 56 is driven by a second belt transmission device 57. A rotating wheel one 36 is also rotatably sleeved on the mounting shaft 2. The rotating wheel one 36 is driven by a first belt transmission device 37;

[0035] A regulating device 3 is coaxially fixed on the rotating wheel one 36;

[0036] A flange 4 is detachably and fixedly assembled on the mounting shaft 2 for installing a resin grinding wheel;

[0037] A dressing device 5 is arranged on the front end side of the mounting shaft 2; and

[0038] An operation screen 7 is arranged on the suitcase 6;

[0039] Through the setting of the suitcase, the mobility flexibility is improved. Specifically, the resin grinding wheel to be dressed is fixedly connected and fixed on the mounting shaft 2 through the cooperation of the flange 4. And the front side of the installed resin grinding wheel coincides with the dressing cone head. Through the operation screen 7, the second belt transmission device 57 is started to drive the resin grinding wheel to rotate counterclockwise, and the first belt transmission device 37 is started to drive the regulating device 3 to continuously rotate clockwise / intermittently rotate clockwise, and cooperate with the dressing device 5, so as to dress the circumferential surface and the circular surface of the resin grinding wheel respectively.

[0040] In this embodiment, the dressing device 5 includes:

[0041] A fixing base two 51 is fixed on the suitcase 6;

[0042] A second telescopic device 52 is installed at the upper end of the fixing base two 51, and a T-shaped dressing flat head 53 is installed at its output end; and

[0043] A fixed shell plate 54 is fixed on one side of the fixing base two 51, and uniformly distributed telescopic dressing push heads 55 are arranged on its outer ring part;

[0044] The T-shaped dressing flat head 53 is regulated by the second telescopic device 52 to be close to one side of the circular surface of the resin grinding wheel to dress the circular surface of the resin grinding wheel. The telescopic dressing push heads 55 cooperate with the regulating device 3 to dress the circumferential surface of the resin grinding wheel.

[0045] In this embodiment, the telescopic dressing push head 55 includes:

[0046] A third telescopic device 551 is fixed on the fixed shell plate 54, and a slide rail two 552 is fixed at its output end;

[0047] The elastic telescopic rod 553 has its lower end fixed to the bottom of the second slide rail 552, and its upper end is fixed with a second slider 554 that is slidably connected in the second slide rail 552. Its lower end is hinged with a trimming push head 558, and a long shaft rod 555 is fixed on the second slider 554. A rotatable pressure roller 557 is sleeved on the long shaft rod 555; and

[0048] The connecting plate 556 has its two ends respectively hinged on the long shaft rod 555 and the trimming push head 558;

[0049] In this embodiment, eight sets of telescopic trimming push heads 55 are provided. Among them, each time the pressure roller in the telescopic trimming push head 55 is pressed, it will push the connecting plate, prompting the trimming push head to act on the circumferential surface of the resin grinding wheel. And it can be adjusted according to the control of the pressing frequency and continuous pressing time of the pressure roller, so as to trim the circumferential surface of the resin grinding wheel in a point-contact or continuous manner. While ensuring efficient trimming, the frictional heat generated during trimming is reduced. At the same time, it is beneficial to improve the service life of the telescopic trimming push head 55. Herein, the elastic telescopic rod 553 is in a compressed state;

[0050] Reference Figure 6 Specifically, during implementation, by adjusting the third telescopic device 551, the second slide rail 552 and the trimming cone head 558 are adjusted to move to the right, thereby trimming the circumferential surface of the resin grinding wheel.

[0051] In this embodiment, a shock-absorbing pad 559 is provided on the second slider 554 to improve the reset stability of the pressure roller 557.

[0052] In this embodiment, the inclination range angle of the trimming push head 558 is 15° to 30°. That is to say, when the upper end of the connecting rod is located at the upper end of the second slide rail 554, the inclination angle of the trimming push head is 30°. When the lower end of the connecting rod moves the maximum amount, the inclination angle of the trimming push head is 15°.

[0053] In this embodiment, the control device 3 includes:

A rotatable pressure roller 324 is installed on the first slider 322. Among them, the telescopic amount of the first telescopic device 323 can be adjusted before / during the trimming process, so as to change the moving amount of the pressure roller pressing the pressure roller, thereby adjusting the acting depth of the trimming cone head, thereby improving the selectivity of the resin grinding wheel trimming control method.

[0056] In this embodiment, ventilation holes 33 are provided on the disk surface of the rotating shell disk 31. A ring frame 34 is fixed on the surface of the ventilation holes 33, and a drainage fan blade 35 is installed on the ring frame 34 to guide the air flow to blow towards the resin grinding wheel, which is beneficial to cooling the working surface of the resin grinding wheel and the dressing cone head, and timely blowing away the trimmed fine chips. At the same time, it avoids the fine chips from being adsorbed on the surface of the dressing push head, affecting the dressing effect of the resin grinding wheel, and further improving the dressing accuracy and quality of the resin grinding wheel.

[0057] During specific implementation, the resin grinding wheel to be dressed is fixedly connected to the mounting shaft 2 through the flange 4, and the front side of the installed resin grinding wheel coincides with the dressing cone head.
