Description

Technical Field

[0001] The utility model relates to the technical field of position adjustment of a guide wheel of a centerless grinder, in particular to a guide wheel platform adjustment device for a centerless grinder. Background Art

[0002] When the centerless grinder is in use, the product is ground by the cooperation of the guide wheel and the grinding wheel. The guide wheel and the grinding wheel are close to each other during the grinding operation, and are separated from each other during the non-grinding operation. Because the power device of the grinding wheel part is more complex and difficult to move, it is generally necessary to adjust the displacement of the guide wheel part.

[0003] The existing guide wheel platform has poor displacement accuracy, resulting in poor product grinding accuracy during guide wheel and grinding wheel grinding operations. At the same time, the existing guide wheel platform generally does not have a fine-tuning structure, which cannot make up for the poor accuracy caused by guide wheel wear, resulting in low product grinding accuracy.

[0004] Patent document No. 202322281367.2 discloses a guide wheel adjustment device for a CNC centerless grinder. This device utilizes a rotatable knob that works in conjunction with an air hole to adjust the dripping rate of lubricating oil from the oil reservoir. This device then uses an oil receiving net to collect the oil, allowing the oil to flow along a thick cotton thread and soak the bristles of a brush. This allows the bristles to lubricate the meshing teeth during adjustment, preventing wear and difficulty adjusting the adjuster due to oil starvation over extended use, thus extending the life of the adjuster. However, this solution also suffers from poor compensation for fine-tuning the guide wheel. Utility Model Content

[0036] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention, and should not be construed as limiting the present invention.

[0037] Example:

[0038] like Figure 1 As shown, the utility model discloses a guide wheel platform adjustment device for a centerless grinder, which includes components such as a bottom platform 100, a slide plate 200, a support assembly 300, a drive assembly 500 and a fine-tuning assembly 400.

[0039] The bottom platform 100 is fixedly mounted on the machine platform 700 to form a bottom support, and the slide plate 200 and other components are all arranged on the bottom platform 100 .

[0040] The top surface of the bottom platform 100 is provided with a slide groove, which is used to set the driving component 500. Specifically:

[0041] The driving assembly 500 includes a servo motor 510, a shaft connector 520, a second screw rod 530, a second nut seat 540, a fixing seat 560 and a second bearing seat 550, etc.

[0042] like Figure 3 As shown, the skateboard 200 is located on the bottom platform 100 and is slidably connected to the bottom platform 100. The skateboard 200 is driven by the driving component 500 to slide radially along the guide wheel 610. The nut seat 2 540 is sleeved on the screw rod 2 530 and forms a screw rod pair with the screw rod 2 530. The nut seat 2 540 is connected to the skateboard 200; one end of the screw rod 2 530 passes through the bearing and is rotatably connected to the bearing seat 2 550 through the bearing. The bearing seat 2 550 is connected to the bottom platform 100 through the fixed seat 560; the servo motor 510 drive shaft is connected to the screw rod 2 530 through the shaft connector 520 and passes through one end of the bearing.

[0043] When in use, the drive assembly 500 is used to drive the skateboard 200 and other components installed on the skateboard 200. Specifically, the servo motor 510 is electrically connected to the grinding machine console, and the servo motor 510 is controlled by the console. When the guide wheel 610 needs to work, the servo motor 510 drives the skateboard 200 through the screw pair, so that the guide wheel 610 is close to the grinding wheel to grind the product together.

[0044] like Figure 2 As shown, the support assembly 300 is located on the skateboard 200 and is slidably connected to the skateboard 200. The support assembly 300 is connected to and supports the guide wheel assembly 600. Specifically:

[0045] like Figure 4 As shown, the support assembly 300 includes a support frame 310 and a mounting frame 320, and the guide wheel assembly 600 includes a guide wheel 610 and a guide wheel driving member 620, wherein:

[0046] The guide wheel 610 is installed in the support frame 310 and is rotatably connected to the support frame 310. The guide wheel driving component 620 is connected to the support frame 310. The guide wheel 610 is driven by the guide wheel driving component 620 to work. The support frame 310 is connected to the installation frame 320, and the installation frame 320 is slidably connected to the slide plate 200.

[0047] The support assembly 300 is driven by the fine-tuning assembly 400 to slide radially along the guide wheel 610, wherein the fine-tuning assembly 400 includes a handwheel 410, a handwheel connector 420, a screw rod 430, a nut seat 440 and a bearing seat 450, etc.

[0048] like Figure 3As shown, screw rod 1 430 is located in the mounting frame and one end passes through the mounting frame 320. Screw rod 1 430 passes through the mounting frame 320 and one end is rotatably connected to bearing seat 1 450 through a bearing, and bearing seat 1 450 is connected to the mounting frame 320; nut seat 1 440 is sleeved on screw rod 1 430 and forms a screw rod pair with screw rod 1 430, and nut seat 1 440 is connected to slide plate 200; handwheel 410 is connected to screw rod 1 430 through handwheel connector 420 and passes through one end of the mounting frame 320.

[0049] When in use, the fine-tuning component 400 controls the support component 300 and the guide wheel component 600 to slide along the skateboard 200. After the guide wheel 610 has been used for a long time, the surface of the guide wheel 610 is worn and polished, and the position of the guide wheel 610 and the grinding wheel needs to be fine-tuned to ensure the accuracy of the grinding of the guide wheel 610 and the grinding wheel. When fine-tuning is required, the handwheel 410 is used to drive the support component 300 and the guide wheel component 600 to slide slightly on the skateboard 200 through the screw pair to adjust the gap between the guide wheel 610 and the grinding wheel during operation.

[0050] Principle of the present invention: The servo motor 510 of the present invention is electrically connected to the grinding machine control console. When the guide wheel 610 is working, the servo motor 510 drives the slide 200 through the screw pair, so that the guide wheel 610 moves closer to or away from the grinding wheel, and the product is ground together; when the surface wear of the guide wheel 610 needs fine-tuning, the hand wheel 410 is used to fine-tune the gap between the guide wheel 610 and the grinding wheel through the screw pair, which can improve the grinding accuracy of the guide wheel 610 and the grinding wheel.
