[0023] The present application provides a multi-grinding wheel switching device for a CNC knife grinder, which is mainly used to solve the problem that the grinding wheel type needs to be frequently replaced and the operation is cumbersome, and provides the following technical solutions, which will be described in detail below:
[0024] Embodiment 1:
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, in some embodiments, an operation panel 1 is included, a slide plate 2 is slidably connected to the operation panel 1, a connecting seat 3 is arranged above the slide plate 2, a first sharpening mechanism 4 and a second sharpening mechanism 5 are arranged on the side of the connecting seat 3, a switching mechanism 6 for convenient switching is arranged between the slide plate 2 and the connecting seat 3, a support column 7 is rotatably provided on the slide plate 2, the other end of the support column 7 is fixed to the bottom of the connecting seat 3, the switching mechanism 6 includes a fixed plate 601 fixedly connected to the top of the slide plate 2 and a disc 602 fixedly connected to the support column 7, and the middle part of the fixed plate 601 is threadedly connected to the A screw rod 603 is connected, and one end of the screw rod 603 away from the fixed plate 601 is threadedly connected to a connecting plate 604 and the end is fixedly connected to a servo motor 605, and a sliding rod 606 is symmetrically fixedly connected to the connecting plate 604, and the sliding rod 606 is slidably connected to the fixed plate 601, and the bottom of the disk 602 is symmetrically rotatably connected to a rotating plate 607, and the end of the rotating plate 607 away from the disk 602 is rotatably connected to a slider 608, one of the sliders 608 is fixedly connected to one sliding rod 606, and the other slider 608 is slidably connected to the other sliding rod 606.
[0026] Specifically: by setting the first knife sharpening mechanism 4 and the second knife sharpening mechanism 5, and the switching mechanism 6 between the slide plate 2 and the connecting seat 3 on the operating panel 1, the operator can easily switch between the first knife sharpening mechanism 4 and the second knife sharpening mechanism 5, which simplifies the operation process, reduces the operation difficulty, and thus improves the overall knife sharpening efficiency.
[0027] The working principle here is: when it is necessary to switch between the first sharpening mechanism 4 and the second sharpening mechanism 5, the switching mechanism 6 is required, the fixed plate 601 is fixed on the top of the support plate, and the disc 602 is fixed on the support column 7, and their function is to form a switching platform so that the support plate can be switched around the support column 7; the screw rod 603 is connected to the middle part of the fixed plate 6011 by a thread, and is connected to the connecting plate 604 at the end away from the fixed plate 601, and the connecting plate 604 is symmetrically fixedly connected with the sliding rod 606, and the sliding rod 606 is slidably connected to the fixed plate 601, and their function is to be driven by the servo motor 605 to realize the movement of the support plate, thereby adjusting the direction of the support plate; the servo motor 605 is the core part of the switching mechanism 6, and the movement of the support plate is realized by driving the screw rod 603. Specifically, the servo motor 605 The thread is connected to the far end of the screw rod 603, and the servo motor 605 is fixed to the bottom of the support plate through the connecting plate 604; the bottom of the rotating plate 607 is symmetrically connected to the slider 608, one of which is fixedly connected to a slide bar 606, and the other slider 608 is slidably connected to the other slide bar 606, and their function is to connect the rotating plate 607 and the support column 7, and realize the rotation of the rotating plate 607 while adjusting the direction of the support plate; the rotating plate 607 is connected to the support column 7 by the bottom of the disc 602, and the rotation range is limited by two sliders 608. When the direction of the support plate changes, the rotating plate 607 will rotate accordingly. By controlling the forward and reverse rotation and the rotation angle of the servo motor 605, the rotation angle of the connecting seat 3 can be accurately controlled to realize the accurate switching of the first sharpening mechanism 4 and the second sharpening mechanism 5. It should be noted that the servo motor 605 is a prior art, and the working principle here will not be repeated.
[0028] like Figure 1 , Figure 2As shown, in some embodiments, a T-shaped block 8 is symmetrically fixed to the bottom of the slide plate 2, a T-shaped slot 9 is symmetrically arranged on the operating plate 1, the T-shaped block 8 slides in the T-shaped slot 9, and a driving mechanism 10 for driving the T-shaped block 8 to slide in the T-shaped slot 9 is arranged on the slide plate 2, and the driving mechanism 10 includes a first bottom plate 1001 fixed to the top of the operating plate 1, an electric push rod 1002 is fixedly installed on the side of the first bottom plate 1001, and a second bottom plate 1003 is fixedly installed on the other end of the electric push rod 1002, and the side of the second bottom plate 1003 is fixedly installed on the side of the slide plate 2. The working principle here is: when the slide plate 2 needs to slide on the operating plate 1, the electric push rod 1002 is started, and the electric push rod 1002 is fixed to the first bottom plate 1001 on the top of the operating plate 1 On the plate 1001, its telescopic end is fixedly connected to the second bottom plate 1003, and the second bottom plate 1003 is fixedly installed on the side of the slide plate 2. When the electric push rod 1002 is extended, it pushes the second bottom plate 1003 and the slide plate 2 connected thereto to move in one direction. At this time, the T-shaped blocks 8 symmetrically fixed at the bottom of the slide plate 2 slide in the T-shaped slots 9 symmetrically arranged on the operating plate 1. The cooperation of the T-shaped blocks 8 and the T-shaped slots 9 ensures the stability and directionality of the sliding of the slide plate 2. When the electric push rod 1002 is shortened, the second bottom plate 1003 and the slide plate 2 are pulled to move in the opposite direction. Similarly, through the cooperation of the T-shaped blocks 8 and the T-shaped slots 9, the smooth retreat of the slide plate 2 is achieved. It should be noted that when the electric push rod 1002 is extended to the longest, that is, Figure 1 As shown, the slide plate 2 will not slide off the operating panel 1 at this time.
[0029] Embodiment 2:
[0030] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:
[0031] like Figure 1 , Figure 3 , Figure 4As shown, in some embodiments, the first knife sharpening mechanism 4 includes a first motor 401 fixed on one side of the connecting seat 3, the output shaft of the first motor 401 is fixedly mounted with a first round rod 402, and the first round rod 402 is fixedly mounted with a first grinding wheel 403 at one end away from the output shaft, and the second knife sharpening mechanism 5 includes a second motor 501 fixed on the other side of the connecting seat 3, the output shaft of the second motor 501 is fixedly mounted with a second round rod 502, and the second round rod 502 is fixedly mounted with a second grinding wheel 503 at one end away from the output shaft, a first protective cover 11 is fixedly mounted on the side of the first motor 401, and a second protective cover 12 is fixedly mounted on the side of the second motor 501. The working principle here is: in the first knife sharpening mechanism 4, when the knife sharpening operation is required, the first motor 401 is started, the output shaft of the first motor 401 drives the first round rod 402 to rotate, and the first grinding wheel 403 fixed on the end of the first round rod 402 rotates at high speed, and the high-speed rotating first grinding wheel 403 contacts with the tool to be ground, and the tool is trimmed and processed by grinding. The first protective cover 11 is set to prevent grinding debris from splashing during the grinding process, protect the safety of the operator, and also reduce the pollution of the debris to the working environment. The working principle of the second grinding mechanism 5 is similar to that of the first grinding mechanism 4. After starting the second motor 501, its output shaft drives the second round rod 502 to rotate, so that the second grinding wheel 503 at the end of the second round rod 502 rotates at a high speed. The second grinding wheel 503 contacts with the tool for grinding to complete the processing of the tool. The second protective cover 12 also plays a role in protection and environmental protection. The first grinding wheel 403 and the second grinding wheel 503 are driven by the first motor 401 and the second motor 501 respectively, and are equipped with corresponding protective covers, so that the multi-grinding wheel switching device of the CNC tool grinder can quickly and safely switch and use between the first grinding mechanism 4 and the second grinding mechanism 5 according to different tool grinding requirements. It should be noted that: the first motor 401 and the second motor 501 are both prior art and are grinding wheel motors, and the working principle is not repeated here. At the same time, both the first sharpening mechanism 4 and the second sharpening mechanism 5 need to use cutting fluid when working.
[0032] Working step 1: When it is necessary to grind the tool, according to the tool's demand for the type of grinding wheel, choose to use the first grinding mechanism 4 or the second grinding mechanism 5. If you want to switch between the two grinding mechanisms, start the servo motor 605 of the switching mechanism 6. The servo motor 605 drives the screw rod 603 to rotate, so that the connecting plate 604 threadedly connected to the screw rod 603 produces a linear motion, and the slide bar 606 on the connecting plate 604 moves accordingly, pushing or pulling the slider 608 connected thereto, and the slider 608 drives the rotating plate 607 to move. The other end of the rotating plate 607 is rotatably connected to the bottom of the disc 602, thereby driving the disc 602 and the connecting plate 604 fixed thereon. The support column 7 and the connecting seat 3 on the disc 602 rotate to realize the switching of the first sharpening mechanism 4 and the second sharpening mechanism 5. During the switching process, the T-shaped block 8 at the bottom of the slide plate 2 slides in the T-shaped groove 9 on the operating panel 1 to ensure the movement stability of the slide plate 2 and the connecting seat 3. The movement of the slide plate 2 is realized by the driving mechanism 10. The electric push rod 1002 in the driving mechanism 10 is fixed on the first bottom plate 1001 on the operating panel 1, and its telescopic end is connected to the second bottom plate 1003 fixed on the side of the slide plate 2. The telescopic movement of the electric push rod 1002 pushes the slide plate 2 to slide on the operating panel 1 to move the selected sharpening mechanism to the working position.
[0033] Working step two: After determining to use a certain sharpening mechanism, such as the first sharpening mechanism 4, start the first motor 401. The output shaft of the first motor 401 drives the first round rod 402 to rotate, so that the first grinding wheel 403 at the end of the first round rod 402 rotates at high speed to grind the tool to be ground. The first protective cover 11 can prevent grinding debris from splashing. Similarly, the second motor 501 of the second sharpening mechanism 5 can drive the second grinding wheel 503 at the end of the second round rod 502 to rotate to grind the tool, and the second protective cover 12 plays the same protective role. In summary, the multi-grinding wheel switching device of the CNC sharpening machine realizes the rapid switching of the grinding wheel and the efficient grinding of the tool through the coordinated work of various parts, simplifies the operation process, and improves the work efficiency and processing accuracy.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
