Description

Technical Field

[0001] The invention relates to the technical field of CNC tool holder assembly and disassembly, and in particular to CNC tool holder assembly and disassembly equipment based on machine vision automatic identification. Background Art

[0002] The CNC tool holder refers to a part of the tool holding system on a machining center or a CNC milling machine. It plays a vital role in CNC machining. The CNC tool holder can connect the tool to the spindle to complete the cutting task. The loading and unloading of the CNC tool holder is an important part of the operation of CNC machine tools. Correct loading and unloading steps are essential to ensure machining quality and improve production efficiency. The loading and unloading of the CNC tool holder is an important part of the operation of CNC machine tools. The operator needs to strictly follow the operating steps and pay attention to related matters and troubleshooting. Through correct loading and unloading operations and maintenance, the normal operation and machining quality of the CNC machine tools can be ensured.

[0003] The prior art has a high rate of work-related accidents in the process of loading and unloading CNC tool holders. In the process of clamping the tool, the wrench is turned by hand. Due to the randomness of manual force, if excessive force is applied, the wrench will be detached and the whole body will fall forward. In this case, the body will inevitably hit the tool head, resulting in work-related accidents of varying degrees. In addition, the torque and torque used each time are different, which seriously affects the product accuracy. Since the torque is manually output, the manually output torque is random, which directly leads to different degrees of clamping the tool by the chuck. During the cutting process, the precision of the cut product is different, thus affecting the quality of the product.

[0004] In the prior art, a Chinese patent with publication number CN219853425U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: CNC tool holder automatic loading and unloading equipment has high safety, improves product precision, increases tool life, improves work efficiency, reduces labor intensity, and thus reduces production costs; it includes a rotating ring, which is elastically mounted with two clamping claws along the radial direction. However, during the use of the above scheme, if tool holders of different sizes are required, an operator needs to manually select a tool holder of a specified size and then replace the tool holder. However, manual selection of tool holders is prone to fatigue and errors, thereby affecting work efficiency. Therefore, it is necessary to propose a CNC tool holder loading and unloading equipment based on automatic recognition of machine vision to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a CNC tool holder loading and unloading device based on automatic recognition by machine vision to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The CNC tool holder loading and unloading equipment based on automatic recognition of machine vision comprises a frame; a fixed plate is fixedly installed on the top of the frame, a rotating plate is fixedly connected to the top of the fixed plate, a motor is fixedly connected to the bottom of the fixed plate, the surface of the top of the output shaft of the motor is fixedly connected to the bottom surface of the rotating plate, a plurality of card slots of different radii are circumferentially provided on the top of the rotating plate, a tool holder body of a size matching the size is clamped inside each card slot, a control panel is fixedly installed on one end of the frame on the top of the rotating plate, a connecting frame is slidably connected to one end of the frame on one side of the control panel, a scanning head is fixedly connected to the bottom of the connecting frame, clamping components are arranged on the bottom of the connecting frame on both sides of the scanning head, and a pulling plate is fixedly installed on one end of the connecting frame.

[0008] The above technical solution is adopted. In this solution, during use, if a tool handle of a different size is needed, the operator needs to manually select a tool handle of a specified size and then replace the tool handle. However, manual selection of the tool handle is prone to fatigue and errors, which affects work efficiency. In the present application, a plurality of slots of different sizes are provided on the surface of the rotating plate, so that tool handle bodies of different sizes can be placed conveniently. The operator sets the tool handle body of a specified radius size to be used, and then drives the rotating plate to rotate by installing a motor, thereby driving the tool handle body to rotate, and each tool handle body is rotated to the scanning head. Directly below, a scanning head can be installed to scan the appearance of each tool handle body according to needs, and the scanning results can be transmitted to the control panel. At the same time, with the help of an image processor, it can be determined which tool handle body is the tool handle body of the specified radius size required by the operator, thereby achieving an automatic identification effect, which can replace the operator's manual operation and improve work efficiency. After selecting the tool handle body of the specified radius size, the operator needs to take the tool handle body out of the slot. In this application, a clamping component is set to realize automatic clamping of the tool handle body, thereby further improving work efficiency.

[0009] A further improvement of the technical solution of the present invention is that each clamping component includes an adjusting plate, a connecting rod is slidably installed inside each adjusting plate, a spring is fixedly connected inside the adjusting plate outside each connecting rod, a baffle is arranged on the outside of each adjusting plate, the inner surface of each baffle is fixedly connected to the outer surface of each connecting rod, and the inner side of each connecting rod extends out of each adjusting plate and is fixedly installed with a clamp.

[0010] The above-mentioned technical scheme is adopted. In this scheme, after selecting a tool handle body of a specified radius, the operator needs to remove the tool handle body from the slot. In this application, the tool handle body can be automatically clamped by setting a clamping component, wherein the connecting frame is moved toward the bottom so that the two adjustment plates are close to the tool handle body to be clamped, and then the two clamps are moved outward for a distance so that the two clamps are moved to both sides of the tool handle body. When no outward pulling force is formed on the clamps, the elastic force of the spring itself can form an inward thrust on the connecting rod, and at the same time drive the clamps to fit with the outer surface of the tool handle body and squeeze the tool handle body to limit the position. In the process of moving the connecting frame toward the top, the tool handle body can move toward the top with the two clamps, thereby realizing automatic clamping of the tool handle body, so as to facilitate the subsequent installation of the tool handle body.

[0011] A further improvement of the technical solution of the present invention is that the inner surface of each baffle is respectively fitted with the outer surface of each adjustment plate.

[0012] The above-mentioned technical scheme is adopted. In this scheme, during the extension and retraction of the spring, the connecting rod is easily caused to shake randomly, thereby affecting the stability of the clamping plate on the knife handle body and reducing the service life of the spring. In the present application, the surface of the baffle plate is fitted with the surface of the adjustment plate. It can be seen that the surface area of ​​the baffle plate is larger than the surface area of ​​the connecting rod, thereby preventing the connecting rod from moving excessively or falling off inside the spring, thereby improving the stability of the clamping plate on the knife handle body, and preventing the spring from being damaged due to excessive compression or stretching, thereby extending the service life of the spring.

[0013] A further improvement of the technical solution of the present invention is that the inner surface of each clamping plate close to the bottom is provided with an inclined surface inclined toward the outer side of the bottom.

[0014] The above technical solution is adopted. In this solution, before using the clamping plate to clamp the knife handle body, it is necessary to first move the clamping plate outward to facilitate the subsequent clamping operation of the knife handle body. In the present application, a slope is provided on the inner side of the clamping plate. During the process of the clamping plate moving toward the bottom, the slope of the clamping plate can first contact with the surface of the knife handle body, and then the knife handle body can reversely squeeze the clamping plate, so that the clamping plate automatically moves outward to facilitate the subsequent clamping operation of the knife handle body. The above method does not require the operator to manually move the clamping plate, thereby reducing the operating steps and improving work efficiency.

[0015] A further improvement of the technical solution of the present invention is that: limit plates are fixedly installed at both ends of each adjustment plate, a limit rod runs through the interior of each limit plate, and the inner surface of each limit rod is fixedly connected to the outer surface of each clamping plate.

[0016] The above-mentioned technical solution is adopted. In this solution, when the splint follows the movement of the connecting rod, the contact area between the connecting rod and the splint is small, and the splint is easy to rotate to both ends, which causes the connecting rod to bend. In this application, by installing a limit plate and a limit rod, when the splint follows the movement of the connecting rod, the limit rod can be driven to slide along the inner wall of the limit plate, thereby reducing the possibility of the splint rotating to both ends and causing the connecting rod to bend, ensuring that the splint can clamp the tool handle body normally.

[0017] A further improvement of the technical solution of the present invention is that an opening larger than the radius of each tool handle body is formed at the top of each slot.

[0018] The above technical solution is adopted. In this solution, an opening larger than the size of the handle body is opened at the top of the slot to facilitate the handle body to be easily inserted into the slot and to be separated from the slot, thereby facilitating subsequent loading and unloading of the handle body.

[0019] A further improvement of the technical solution of the present invention is that a plurality of balls are rotatably mounted inside the fixed plate, and the top of each ball extends out of the interior of the fixed plate and fits against the bottom surface of the rotating plate.

[0020] By adopting the above technical solution, the contact area between the fixed plate and the rotating plate can be reduced by installing ball bearings. During the rotation of the rotating plate, the ball bearings can rotate along with the rotating plate, thereby reducing the wear between the fixed plate and the rotating plate and extending the service life of the fixed plate and the rotating plate.

[0021] A further improvement of the technical solution of the present invention is that a pull plate is fixedly installed at one end of the connecting frame.

[0022] The above technical solution is adopted. In this solution, by installing a pull plate, it is convenient for the operator to resolve the contact between the operator and the clamping component, thereby facilitating pulling the connecting frame to move the clamping component.

[0023] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0024] 1. The present invention provides a CNC tool handle loading and unloading device based on automatic recognition of machine vision. By inserting tool handle bodies of different sizes into slots of specified sizes and installing a motor to drive a rotating plate to rotate, each tool handle body can be rotated to the position directly below a scanning head. The scanning head is then used to scan the appearance of each tool handle body, and the scanning result is transmitted to a control panel. At the same time, in cooperation with an image processor, it is possible to determine which tool handle body is the tool handle body of the specified radius required by the operator, thereby achieving an automatic recognition effect. A clamping component is used to clamp the tool handle body of the specified size, thereby replacing the manual operation of the operator, thereby improving work efficiency.

[0025] 2. The present invention provides a CNC tool handle loading and unloading device based on automatic recognition of machine vision. By setting a clamping component, the tool handle body can be automatically clamped. By making the surface of the baffle plate fit with the surface of the adjustment plate, the connecting rod can be prevented from excessively moving or falling off inside the spring, thereby solving the problem that during the extension and contraction of the spring, the connecting rod is easily driven to shake randomly, thereby affecting the stability of the clamping plate clamping the tool handle body and reducing the service life of the spring; and by providing an inclined surface on the inner side of the clamping plate, the inclined surface of the clamping plate can first contact with the surface of the tool handle body, and then the tool handle body can reversely squeeze the clamping plate, so that the clamping plate automatically moves outward, without the need for the operator to manually move the clamping plate, thereby reducing the operation steps and improving work efficiency; the use of a limit rod and a limit plate can improve the strength of the clamping plate, and in the process of the clamping plate following the movement of the connecting rod, the limit rod can synchronously slide along the inner wall of the limit plate, thereby reducing the possibility of the clamping plate rotating to both ends and causing the connecting rod to bend, ensuring that the clamping plate can clamp the tool handle body normally.

[0026] 3. The present invention provides a CNC tool handle loading and unloading device based on automatic recognition by machine vision. By opening an opening larger than the size of the tool handle body at the top of the slot, the tool handle body can be easily inserted into the interior of the slot and easily separated from the interior of the slot, thereby further improving the efficiency of the tool handle body being connected and disassembled.

[0027] 4. The present invention provides a CNC tool holder loading and unloading device based on automatic recognition of machine vision. During the rotation of the rotating plate, the ball bearing can rotate along with the rotating plate, and the ball bearing reduces the contact area between the fixed plate and the rotating plate, thereby reducing the wear between the fixed plate and the rotating plate and extending the service life of the fixed plate and the rotating plate.

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below in conjunction with embodiments:

[0038] Example 1

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, the present invention provides a CNC tool handle loading and unloading device based on machine vision automatic identification, including a frame 1; a fixed plate 2 is fixedly installed on the top of the frame 1, a rotating plate 3 is fixedly connected to the top of the fixed plate 2, a motor 9 is fixedly connected to the bottom of the fixed plate 2, the surface of the top of the output shaft of the motor 9 is fixedly connected to the bottom surface of the rotating plate 3, a plurality of card grooves 11 with different radii are circumferentially opened on the top of the rotating plate 3, and a tool handle body 6 of a size matching the card groove 11 is clamped inside each card groove 11, a control panel 4 is fixedly installed on one end of the frame 1 on the top of the rotating plate 3, a connecting frame 7 is slidably connected to one end of the frame 1 on one side of the control panel 4, a scanning head 12 is fixedly connected to the bottom of the connecting frame 7, a clamping component 5 is provided at the bottom of the connecting frame 7 on both sides of the scanning head 12, a pull plate 8 is fixedly installed on one end of the connecting frame 7, and a pull plate 8 is fixedly installed on one end of the connecting frame 7.

[0040] In this embodiment, during use, if a tool handle of a different size is required, the operator needs to manually select a tool handle of a specified size and then replace the tool handle. However, manual selection of the tool handle is prone to fatigue and errors, which affects work efficiency. In this application, a plurality of slots 11 of different sizes are provided on the surface of the rotating plate 3 to facilitate the placement of tool handle bodies 6 of different sizes. The operator sets the tool handle body 6 of a specified radius size to be used, and then drives the rotating plate 3 to rotate by installing a motor 9, thereby driving the tool handle body 6 to rotate, and each tool handle body 6 is rotated to the position directly below the scanning head 12. Then, by installing the scanning head 12, the appearance of each handle body 6 can be scanned and processed separately as needed, and the scanning results can be transmitted to the control panel 4. At the same time, with the help of the image processor, it can be determined which handle body 6 is the handle body 6 of the specified radius size required by the operator, thereby achieving an automatic identification effect, which can replace the operator's manual operation and improve work efficiency. After selecting the handle body 6 of the specified radius size, the operator needs to take the handle body 6 out of the slot 11. In this application, the clamping component 5 is provided to realize automatic clamping of the handle body 6, thereby further improving work efficiency.

[0041] Example 2

[0042] like Figure 1 , Figure 5 and Figure 6 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, each clamping component 5 includes an adjusting plate 501, a connecting rod 504 is slidably installed inside each adjusting plate 501, a spring 503 is fixedly connected inside the adjusting plate 501 outside each connecting rod 504, a baffle 507 is arranged on the outside of each adjusting plate 501, the inner surface of each baffle 507 is respectively fixedly connected to the outer surface of each connecting rod 504, the inner side of each connecting rod 504 extends out of each adjusting plate 501 and a clamping plate 502 is fixedly installed, the inner surface of each baffle 507 is respectively fitted with the outer surface of each adjusting plate 501, the inner surface of each clamping plate 502 near the bottom is provided with an inclined surface inclined toward the outer side of the bottom, and limiting plates 506 are fixedly installed at both ends of each adjusting plate 501, the interior of each limiting plate 506 is penetrated by a limiting rod 505, and the inner surface of each limiting rod 505 is respectively fixedly connected to the outer surface of each clamping plate 502.

[0043] In this embodiment, after selecting the knife handle body 6 of the specified radius, the operator needs to take the knife handle body 6 out of the slot 11. In this application, the clamping component 5 is provided to realize the automatic clamping of the knife handle body 6, wherein the connecting frame 7 is moved toward the bottom so that the two adjustment plates 501 are close to the knife handle body 6 to be clamped, and then the two clamping plates 502 are moved outward for a distance so that the two clamping plates 502 are moved to both sides of the knife handle body 6. When no outward pulling force is formed on the clamping plates 502, the elastic force of the spring 503 itself can form an inward pushing force on the connecting rod 504, thereby driving the clamping plates 502 to fit with the outer surface of the knife handle body 6 and tightening the knife handle. The main body 6 is squeezed and limited. In the process of moving the connecting frame 7 to the top, the handle body 6 can move toward the top with the two clamping plates 502, thereby automatically clamping the handle body 6 to facilitate the subsequent installation of the handle body 6; in the process of the spring 503 extending and retracting, it is easy to drive the connecting rod 504 to shake at will, thereby affecting the stability of the clamping of the handle body 6 by the clamping plate 502 and reducing the service life of the spring 503. In this application, the surface of the baffle plate 507 is fitted with the surface of the adjusting plate 501. It can be seen that the surface area of ​​the baffle plate 507 is larger than the surface area of ​​the connecting rod 504, thereby preventing the connecting rod 504 from excessively moving or coming off inside the spring 503. The clamping plate 502 can be easily pulled out of the handle 6, and the spring 503 can be easily pulled out of the handle 6. The operator manually moves the clamp 502, thereby reducing the number of operating steps and improving work efficiency; in the process of the clamp 502 following the movement of the connecting rod 504, the contact area between the connecting rod 504 and the clamp 502 is small, and the clamp 502 is easy to rotate to both ends, which causes the connecting rod 504 to bend. In the present application, by installing the limit plate 506 and the limit rod 505, in the process of the clamp 502 following the movement of the connecting rod 504, the limit rod 505 can be driven to slide along the inner wall of the limit plate 506, thereby reducing the possibility of the clamp 502 rotating to both ends and causing the connecting rod 504 to bend, ensuring that the clamp 502 can normally clamp the handle body 6.

[0044] Example 3

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, based on Example 2, the present invention provides a technical solution: preferably, the top of each slot 11 is provided with an opening larger than the radius of each handle body 6.

[0046] In this embodiment, an opening larger than the handle body 6 is opened at the top of the slot 11 to facilitate the handle body 6 to be easily inserted into the slot 11 and to be separated from the slot 11, thereby facilitating subsequent loading and unloading of the handle body 6.

[0047] Example 4

[0048] like Figure 1 , Figure 2 and Figure 4 As shown, based on Example 3, the present invention provides a technical solution: preferably, a plurality of balls 10 are rollingly installed inside the fixed plate 2, and the top of each ball 10 extends out of the interior of the fixed plate 2 and fits with the bottom surface of the rotating plate 3.

[0049] In this embodiment, the contact area between the fixed plate 2 and the rotating plate 3 can be reduced by installing the ball 10. During the rotation of the rotating plate 3, the ball 10 can rotate along with the rotating plate 3, thereby reducing the wear between the fixed plate 2 and the rotating plate 3 and extending the service life of the fixed plate 2 and the rotating plate 3.

[0050] The working principle of the CNC tool holder loading and unloading equipment based on automatic recognition by machine vision is explained in detail below.

[0051] like Figure 1-Figure 7 As shown, the operator first connects the handle bodies 6 of different sizes to each slot 11, and then sets the handle body 6 of the specified radius size to be used, and then uses the motor 9 to drive the rotating plate 3 to rotate, thereby driving each handle body 6 to rotate, and then rotates each handle body 6 to the bottom of the scanning head 12 in turn, and then uses the scanning head 12 to scan the appearance of the handle body 6, and transmits the scanning result to the control panel 4, and cooperates with the image processor to determine the handle body 6 that meets the specified set size. The motor 9 stops driving the rotating plate 3 to rotate, and the operator moves the connecting frame 7 to the bottom so that the clamping plate 502 is close to the handle body 6. The handle body 6 then squeezes the two clamping plates 502 in the opposite direction, and then uses the spring 503 to push the clamping plate 502, so that the clamping plate 502 can be used to clamp the handle body 6, and then the connecting frame 7 is moved to the top, so that the handle body 6 can be clamped.

[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
