Description

Technical Field

[0001] The invention relates to the technical field of numerical control equipment, and in particular to a high-precision repeated positioning combined numerical control tool handle automatic loading and unloading device. Background Art

[0002] CNC tools are crucial cutting tools in the field of mechanical manufacturing. They are precisely controlled by CNC systems to achieve high-precision and high-efficiency automated processing processes. They are widely used in many industries such as automobiles, aerospace, and mold manufacturing. CNC tools are usually composed of accessories such as blades, tool bars, and tool holders. According to different processing requirements, they can be divided into various types and specifications to meet the processing needs of various materials and shapes. During the processing process, CNC tools cut or process the workpiece into the desired shape by rotating, cutting, drilling, etc. At the same time, the CNC system also has functions such as tool position detection, cutting force and heat control to ensure processing accuracy and tool life.

[0003] In the prior art, tool replacement is generally performed manually. When a tool needs to be loaded, a worker puts a tool of different types into a tool handle clamp, and then selects a wrench that matches the tool handle and rotates the wrench clockwise until a certain tightness is felt. After the tool is loaded, the tool handle is removed. The tool unloading process is to rotate the wrench counterclockwise until the tool is unloaded.

[0004] However, manual tool replacement has certain disadvantages. First, manual loading and unloading of tools requires workers to do it one by one. In the processing process that requires frequent tool replacement, manual loading and unloading and the use of different tools will take up a lot of time, affecting the overall processing efficiency; secondly, due to the limitations of manual operation, it may not be possible to achieve the ideal matching accuracy every time, which affects the processing quality and tool life, and then affects the processing accuracy and workpiece quality. Summary of the invention

[0005] The purpose of the present invention is to provide a high-precision repeated positioning combined CNC tool holder automatic loading and unloading device 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] A high-precision repeated positioning combined CNC tool holder automatic loading and unloading device, comprising:

[0008] A workbench, an automatic loading and unloading component is arranged above the workbench, the automatic loading and unloading component is used to automatically load and unload the tool handle, the workbench is used to drive the automatic loading and unloading component to move up and down, and a clamping table is fixedly connected to the workbench;

[0009] Automatic loading and unloading components include:

[0010] The shell is slidably connected to the workbench, a groove is provided on the shell, a handle and a control panel are fixedly connected to the front end of the shell, a driving motor is fixedly connected to the top of the shell, a first motor is symmetrically arranged and fixedly connected to both sides of the shell, and a second motor is fixedly connected to the side of the shell close to the first motor;

[0011] A loading and unloading assembly is located inside the shell and is used for loading and unloading the tool handle;

[0012] An adjustment component, which is located outside the loading and unloading component and is used to adjust the loading and unloading component so that the loading and unloading component can load and unload tool handles of different specifications;

[0013] The driving assembly is located above the loading and unloading assembly and is used to provide power for the loading and unloading assembly.

[0014] When the tool handle needs to be disassembled, the tool rod is fixed by the clamping table on the workbench (wherein, the workbench and the clamping table are mature technologies in the prior art, so they will not be described in detail in this article), and then the shell is moved by the handle and the control panel to make the shell rise and fall. When the shell moves from top to bottom until the tool handle enters the loading and unloading assembly, the power is transmitted to the loading and unloading assembly by the driving assembly, and the tool handle is loaded and unloaded by the loading and unloading assembly. When tool handles of different specifications need to be loaded and unloaded, the adjustment assembly is controlled by the control panel to work, thereby adjusting the loading and unloading assembly so that the loading and unloading assembly can load and unload tool handles of different specifications. The tool handle can be conveniently and quickly loaded and unloaded by driving the driving motor to drive the driving assembly and the loading and unloading assembly. The loading and unloading assembly can be quickly adjusted by the adjusting assembly, so that the loading and unloading assembly can quickly adapt to tool handles of different specifications, thereby improving the overall processing efficiency, and at the same time ensuring the accuracy of tool handle loading and unloading, thereby preventing the processing accuracy and workpiece quality from being affected by the low accuracy of tool handle loading and unloading.

[0015] A further improvement of the technical solution of the present invention is that: the loading and unloading assembly includes a rotating disk, the rotating disk is rotatably connected to the shell, a through groove is opened on the rotating disk, sliding grooves are symmetrically opened on the rotating disk, a screw rod is symmetrically arranged and rotatably connected on the rotating disk, a first slider is threadedly connected on the screw rod, the first slider is slidably connected to the sliding groove, and the bottom of the first slider is fixedly connected to a limiting block.

[0016] The above technical solution is adopted. In this solution, when the tool handle needs to be loaded and unloaded, the shell is pulled downward by the handle so that the limit block fixedly connected under the slider is inserted into the keyway of the tool handle, and then the drive motor is started. The drive motor will transmit power to the rotating disk through the drive assembly. At this time, the rotating disk rotates relative to the shell. The rotation of the rotating disk will drive the first slider to revolve through the slide groove and the screw rod, thereby driving the limit block fixedly connected to it to rotate. The rotation of the limit block will drive the tool handle to rotate through the keyway, thereby achieving the purpose of loading and unloading the tool handle. By setting the limit block to be inserted into the tool handle through the keyway and then rotating it, the effect of quick loading and unloading of the tool handle can be achieved (wherein, the through groove is provided so as not to affect the tool during loading and unloading). At the same time, the control panel controls the drive motor to drive the rotating disk to rotate through the drive assembly to tighten the tool handle, which can effectively control the accuracy of loading and unloading of the tool handle, thereby improving the overall processing efficiency while preventing the processing accuracy and workpiece quality from being affected by the low accuracy of loading and unloading of the tool handle.

[0017] A further improvement of the technical solution of the present invention is that: the adjustment component includes a shaft body, the shaft body is rotatably connected to the shell, one end of the shaft body is fixedly connected to the output end of the first motor, the end of the shaft body away from the first motor is arranged in an I-shape, a first through hole is symmetrically provided on the shaft body, one end of the screw rod is hollowly provided inside, a second through hole is symmetrically provided on the screw rod, a first movable block is slidably connected to the shaft body, an end of the first movable block close to the screw rod is symmetrically provided with a fixedly connected through shaft, a second movable block is slidably connected inside the screw rod, an end of the second movable block close to the shaft body is symmetrically provided with a fixedly connected through shaft, the through shaft is slidably connected to the first through hole and the second through hole respectively, an end of the second movable block away from the through shaft is fixedly connected to a pressure spring, and the other end of the pressure spring is fixedly connected to the first screw rod;

[0018] The adjusting assembly also includes a rotating shaft and a second slider. A movable groove is provided on the shell. Threads are provided in partial areas symmetrically arranged on the rotating shaft. The rotating shaft is rotatably connected to the shell. The second slider is threadedly connected to the rotating shaft through threads. The second slider is slidably connected to the movable groove. One end of the second slider away from the rotating shaft is fixedly connected to the first movable block, and one end of the rotating shaft is fixedly connected to the output end of the second motor.

[0019] The above technical solution is adopted, in which when it is necessary to load and unload tool handles of different specifications, the second motor is controlled by the control panel to drive the rotating shaft to rotate. Because the second slider is slidably connected to the movable groove, the second slider threaded on the rotating shaft will move toward each other along the direction of the axis of the rotating shaft. The movement of the second slider will drive the first movable block fixedly connected thereto to move. The through shaft symmetrically arranged through the first movable block and one side of the first movable block rests against the through shaft fixedly connected to one side of the second movable block, and then the second movable block is pushed to move. The movement of the second movable block will squeeze the pressure spring, and the pressure spring is in a compressed state. At this time, the through shaft fixedly connected to the first movable block enters the second through slot located at one end of the screw rod through the first through slot. Then the first motor is controlled to rotate by the controller, and the rotation of the first motor will The shaft body fixedly connected to the output end drives the first movable block slidably connected to the shaft body to rotate, and the first movable block will drive the screw to rotate through the through shaft and the second through hole fixedly connected thereto. Because the first slider is slidably connected to the slide groove, the rotation of the screw will drive the first slider threadedly connected thereto to move along the direction of the axis of the rotating shaft. The movement directions of the symmetrically arranged first sliders are opposite. At this time, by adjusting the distance between the symmetrically arranged first sliders, the limit block can be inserted into the keyway of the tool handle of different specifications, so that the tool handle of different specifications can be loaded and unloaded. When the adjustment is completed, the first motor stops and the second motor is controlled to reverse. At this time, the second slider will reset, and the through shaft fixedly connected to the first movable block will disengage from the second through hole and stop at the connection between the rotating disk and the shell, and the pressure spring will reset. By setting an adjustment component to adjust the limit block, it is not necessary to frequently use different tools for operation, thereby shortening the operation time and improving the overall processing efficiency.

[0020] A further improvement of the technical solution of the present invention is that a weight-reducing groove is provided on the second movable block.

[0021] By adopting the above technical solution, the weight of the second movable block can be reduced by providing a weight-reducing groove on the second movable block, thereby reducing the workload of the driving motor.

[0022] A further improvement of the technical solution of the present invention is that: the driving assembly includes a first gear and a second gear, the second gear is provided with a connecting groove and is rotatably connected to the shell, the second gear is fixedly connected to a connecting block, the other end of the connecting block is fixedly connected to the rotating disk, the first gear is located on the outside of the second gear and is fixedly connected to the output end of the driving motor, the first gear is meshed with the second gear, and the diameter of the first gear is smaller than the diameter of the second gear.

[0023] The above technical solution is adopted. In this solution, when the tool handle needs to be loaded and unloaded, the drive motor is started through the control panel. The drive motor will drive the first gear fixedly connected to its output end to rotate. The rotation of the first gear will drive the second gear meshing with it to rotate, thereby driving the rotating disk to rotate through the connecting block, thereby realizing the disassembly of the tool handle. (Wherein, the connection groove is provided in order not to affect the tool during loading and unloading) By providing a small gear to drive the large gear to rotate, the space required can be reduced, thereby reducing the size of the equipment.

[0024] A further improvement of the technical solution of the present invention is that a plurality of balls are evenly arranged and rollingly connected on one side of the limit block along the height direction, and the balls are used in conjunction with the tool handle.

[0025] The above technical solution is adopted. In this solution, because the tool handle and the tool rod are threadedly connected when the limit block drives the tool handle to rotate, the tool handle will move downward when it rotates. By providing a ball bearing to contact the tool handle, the contact area between the limit rod and the tool handle can be reduced, thereby reducing friction, reducing losses, and extending the service life of the limit rod.

[0026] A further improvement of the technical solution of the present invention is that a buffer layer is provided at the bottom of the limit block, and the material of the buffer layer is rubber.

[0027] By adopting the above technical solution, there is a probability that when the handle is pulled downward, the bottom of the limit block will directly contact the knife handle, thereby damaging the knife handle. By providing a buffer layer of rubber material at the bottom of the limit block, the pressure can be absorbed and dispersed, thereby avoiding damage to the knife handle, thereby improving the overall processing efficiency.

[0028] A further improvement of the technical solution of the present invention is that wear-resistant layers are provided on both side surfaces of the limit block, and the material of the wear-resistant layers is tungsten carbide.

[0029] By adopting the above technical solution, a wear-resistant layer made of tungsten carbide is provided on the surfaces of both sides of the limit block, which can reduce the wear caused by friction between the limit block and the tool handle during operation, thereby effectively extending the service life of the limit block and improving the overall processing efficiency.

[0030] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0031] 1. The present invention provides a high-precision repeated positioning combined CNC tool handle automatic loading and unloading device. When the tool handle needs to be disassembled, the tool rod is fixed by the clamping table on the workbench (wherein, the workbench and the clamping table are mature technologies in the prior art, so they are not described in detail in this article), and then the shell is moved by the handle and the controller to make the shell rise and fall. When the shell moves from top to bottom until the tool handle enters the loading and unloading assembly, the power is transmitted to the loading and unloading assembly through the driving assembly, and the tool handle is loaded and unloaded through the loading and unloading assembly. When different specifications need to be disassembled, the tool handle is fixed by the clamping table on the workbench (wherein, the workbench and the clamping table are mature technologies in the prior art, so they are not described in detail in this article), and then the shell is moved by the handle and the controller to make the shell rise and fall. When the shell moves from top to bottom until the tool handle enters the loading and unloading assembly, the power is transmitted to the loading and unloading assembly through the driving assembly, and the tool handle is loaded and unloaded through the loading and unloading assembly. When the tool handle is loaded and unloaded, the adjustment component is controlled by the control panel to work, thereby adjusting the loading and unloading component so that the loading and unloading component can load and unload tool handles of different specifications. The tool handle can be loaded and unloaded conveniently and quickly by driving the driving component and the loading and unloading component through the driving motor. The loading and unloading component can be quickly adjusted by the adjustment component so that the loading and unloading component can be quickly adapted to tool handles of different specifications, thereby improving the overall processing efficiency and ensuring the accuracy of loading and unloading of the tool handle at the same time, thereby preventing the processing accuracy and workpiece quality from being affected by the low accuracy of loading and unloading of the tool handle.

[0032] 2. The present invention provides a high-precision repeatable positioning combined CNC tool holder automatic loading and unloading device. When the tool holder needs to be loaded and unloaded, the housing is pulled downward by the handle so that the limit block fixedly connected below the slider is inserted into the keyway of the tool holder. Then the drive motor is started, and the drive motor transmits power to the rotating disk through the drive assembly. At this time, the rotating disk rotates relative to the housing. The rotation of the rotating disk drives the first slider to revolve through the slide groove and the screw rod, thereby driving the limit block fixedly connected thereto to rotate. The rotation of the limit block drives the tool holder to rotate through the keyway, thereby achieving the purpose of loading and unloading the tool holder. By setting the limit block to be inserted into the tool holder through the keyway and then rotating it, the effect of fast loading and unloading the tool holder can be achieved (wherein, the through groove is provided so as not to affect the tool during loading and unloading). At the same time, the control panel controls the drive motor to drive the rotating disk to rotate through the drive assembly to tighten the tool holder, which can effectively control the loading and unloading accuracy of the tool holder, thereby improving the overall processing efficiency while preventing the processing accuracy and workpiece quality from being affected by the low loading and unloading accuracy of the tool holder.

[0033] 3. The present invention provides a high-precision repeatable positioning combined CNC tool holder automatic loading and unloading device. When tool holders of different specifications need to be loaded and unloaded, the control panel is used to control the second motor to drive the rotating shaft to rotate. Because the second slider is slidably connected to the movable groove, the second slider threaded on the rotating shaft will move toward each other along the direction of the rotating shaft axis. The movement of the second slider will drive the first movable block fixedly connected to it to move. The through shaft symmetrically arranged through the first movable block and one side of the first movable block is pressed against the through shaft fixedly connected to one side of the second movable block, and then the second movable block is pushed to move. The movement of the second movable block will squeeze the pressure spring, and the pressure spring is in a compressed state. At this time, the through shaft fixedly connected to the first movable block enters the second through groove located at one end of the screw rod through the first through groove. Then the controller is used to control the first motor to rotate, and the first motor The rotation of the machine will drive the first movable block slidably connected to the shaft body to rotate through the shaft body fixedly connected to its output end. The first movable block will drive the screw to rotate through the through shaft and the second through hole fixedly connected to it. Because the first slider is slidably connected to the slide groove, the rotation of the screw will drive the first slider threadedly connected to it to move along the direction of the axis of the rotating shaft. The movement direction of the symmetrically arranged first slider is opposite. At this time, by adjusting the distance between the symmetrically arranged first sliders, the limit block can be inserted into the keyway of the tool handle of different specifications, so that the tool handle of different specifications can be loaded and unloaded. When the adjustment is completed, the first motor stops and the second motor is controlled to reverse. At this time, the second slider will reset, and the through shaft fixedly connected to the first movable block will disengage from the second through hole and stop at the connection between the rotating disk and the shell, and the pressure spring will reset. By setting an adjustment component to adjust the limit block, it is not necessary to frequently use different tools for operation, thereby shortening the operation time and improving the overall processing efficiency.

[0043] The present invention is further described in detail below in conjunction with embodiments:

[0050] An adjustment component, the adjustment component is located outside the loading and unloading component, and the adjustment component is used to adjust the loading and unloading component so that the loading and unloading component can load and unload tool handles 32 of different specifications;

[0051] The driving assembly is located above the loading and unloading assembly and is used to provide power for the loading and unloading assembly.

[0052] In this embodiment, when the tool handle 32 needs to be disassembled, the tool rod is fixed by the clamping table on the workbench 1 (wherein, the workbench 1 and the clamping table are mature technologies in the prior art, so they are not described in detail in this article), and then the shell 2 is moved by the handle 4 and the control panel to make the shell 2 rise and fall. When the shell 2 moves from top to bottom until the tool handle 32 enters the loading and unloading assembly, the power is transmitted to the loading and unloading assembly through the driving assembly, and the tool handle 32 is loaded and unloaded through the loading and unloading assembly. When tool handles 32 of different specifications need to be loaded and unloaded, the control panel is used to control the tool handle 32. The control panel 5 controls the adjustment component to work, thereby adjusting the loading and unloading component, so that the loading and unloading component can load and unload tool handles 32 of different specifications. The driving motor 6 drives the driving component and the loading and unloading component to cooperate with each other, so that the tool handle 32 can be loaded and unloaded conveniently and quickly. The adjustment component can quickly adjust the loading and unloading component, so that the loading and unloading component can be quickly adapted to tool handles 32 of different specifications, thereby improving the overall processing efficiency. At the same time, it can also ensure the accuracy of loading and unloading of the tool handle 32, thereby preventing the processing accuracy and workpiece quality from being affected by the low accuracy of loading and unloading of the tool handle 32.

[0053] like Figure 3 and Figure 4 As shown, in the present embodiment, preferably, the loading and unloading assembly includes a rotating disk 9, which is rotatably connected to the shell 2, a through groove 10 is opened on the rotating disk 9, a sliding groove 11 is symmetrically opened on the rotating disk 9, a screw rod 12 is symmetrically arranged and rotatably connected on the rotating disk 9, a first slider 13 is threadedly connected to the screw rod 12, the first slider 13 is slidably connected to the sliding groove 11, and a limiting block 14 is fixedly connected to the bottom of the first slider 13.

[0054] When the tool handle 32 needs to be loaded and unloaded, the housing 2 is pulled downward by the handle 4 so that the limit block 14 fixedly connected below the slider is inserted into the keyway of the tool handle 32, and then the drive motor 6 is started. The drive motor 6 will transmit power to the rotating disk 9 through the drive assembly. At this time, the rotating disk 9 rotates relative to the housing 2. The rotation of the rotating disk 9 will drive the first slider 13 to revolve through the slide groove 11 and the screw rod 12, thereby driving the limit block 14 fixedly connected thereto to rotate. The rotation of the limit block 14 will drive the tool handle 32 to rotate through the keyway, thereby achieving the purpose of loading and unloading the tool handle 32. By setting the limit block 14 to be inserted into the tool handle 32 through the keyway and then rotating it, the effect of quickly loading and unloading the tool handle 32 can be achieved (wherein, the through groove 10 is provided so as not to affect the tool during loading and unloading). At the same time, by controlling the drive motor 6 through the control panel 5 to drive the rotating disk 9 to rotate through the drive assembly to tighten the tool handle 32, the loading and unloading accuracy of the tool handle 32 can be effectively controlled, thereby improving the overall processing efficiency while preventing the processing accuracy and workpiece quality from being affected by the low loading and unloading accuracy of the tool handle 32.

[0055] like Figure 5 , Figure 6 and Figure 7 As shown, preferably, the adjustment component includes a shaft body 15, the shaft body 15 is rotatably connected to the housing 2, one end of the shaft body 15 is fixedly connected to the output end of the first motor 7, the end of the shaft body 15 away from the first motor 7 is arranged in an I-shape, a first through hole 16 is symmetrically provided on the shaft body 15, one end of the screw rod 12 is hollowly provided inside, a second through hole 17 is symmetrically provided on the screw rod 12, a first movable block 18 is slidably connected to the shaft body 15, an end of the first movable block 18 close to the screw rod 12 is symmetrically provided with a through shaft 19 for fixed connection, a second movable block 20 is slidably connected inside the screw rod 12, an end of the second movable block 20 close to the shaft body 15 is symmetrically provided with a through shaft 19 for fixed connection, the through shaft 19 is slidably connected to the first through hole 16 and the second through hole 17 respectively, an end of the second movable block 20 away from the through shaft 19 is fixedly connected to a pressure spring 21, and the other end of the pressure spring 21 is fixedly connected to the first screw rod 12;

[0056] The adjusting assembly also includes a rotating shaft 24 and a second slider 23. A movable groove 22 is opened on the shell 2. A thread is set in a partial area symmetrically arranged on the rotating shaft 24. The rotating shaft 24 is rotatably connected to the shell 2. The second slider 23 is threadedly connected to the rotating shaft 24 through a thread. The second slider 23 is slidably connected to the movable groove 22. One end of the second slider 23 away from the rotating shaft 24 is fixedly connected to the first movable block 18, and one end of the rotating shaft 24 is fixedly connected to the output end of the second motor 8.

[0057] When it is necessary to load and unload tool handles 32 of different specifications, the second motor 8 is controlled by the control panel 5 to drive the rotating shaft 24 to rotate. Since the second slider 23 is slidably connected to the movable groove 22, the second slider 23 threadedly connected on the rotating shaft 24 will move toward each other along the direction of the axis of the rotating shaft 24. The movement of the second slider 23 will drive the first movable block 18 fixedly connected thereto to move. The through shaft 19 symmetrically arranged through the first movable block 18 and one side thereof is pressed against the through shaft 19 fixedly connected to one side of the second movable block 20, and then the second movable block 20 is pushed to move. The movement of the second movable block 20 will squeeze the pressure spring 21, and the pressure spring 21 is in a compressed state. At this time, the through shaft 19 fixedly connected to the first movable block 18 enters the second through groove 10 opened at one end of the screw rod 12 through the first through groove 10, and then the first motor 7 is controlled to rotate by the controller. The rotation of the first motor 7 will be The shaft body 15 drives the first movable block 18 slidably connected to the shaft body 15 to rotate, and the first movable block 18 will drive the screw rod 12 to rotate through the through shaft 19 and the second through hole 17 fixedly connected thereto. Because the first sliding block 13 is slidably connected to the slide groove 11, the rotation of the screw rod 12 will drive the first sliding block 13 threadedly connected thereto to move along the direction of the axis of the rotating shaft 24, and the movement directions of the symmetrically arranged first sliding blocks 13 are opposite. At this time, by adjusting the distance between the symmetrically arranged first sliding blocks 13, the limit block 14 can be inserted into the keyway of tool handles 32 of different specifications, so that tool handles 32 of different specifications can be loaded and unloaded. When the adjustment is completed, the first motor 7 stops and the second motor 8 is controlled to reverse. At this time, the second sliding block 23 will be reset, and the through shaft 19 fixedly connected to the first movable block 18 will be disengaged from the second through hole 17 and stop at the connection between the rotating disk 9 and the housing 2, and the pressure spring 21 will be reset. By providing an adjustment component to adjust the limit block 14, it is not necessary to frequently use different tools for operation, thereby shortening the operation time and improving the overall processing efficiency.

[0058] like Figure 7 As shown, preferably, a weight-reducing groove 25 is provided on the second movable block 20 .

[0059] By providing the weight-reducing groove 25 on the second movable block 20 , the weight of the second movable block 20 can be reduced, thereby reducing the workload of the driving motor 6 .

[0060] like Figure 4As shown, preferably, the driving assembly includes a first gear 26 and a second gear 27, the second gear 27 is provided with a connecting groove and is rotatably connected to the housing 2, the second gear 27 is fixedly connected to a connecting block 28, the other end of the connecting block 28 is fixedly connected to the rotating disk 9, the first gear 26 is located on the outer side of the second gear 27 and is fixedly connected to the output end of the driving motor 6, the first gear 26 is meshed with the second gear 27, and the diameter of the first gear 26 is smaller than the diameter of the second gear 27.

[0061] When the tool handle 32 needs to be loaded and unloaded, the drive motor 6 is started through the control panel 5. The drive motor 6 will drive the first gear 26 fixedly connected to its output end to rotate. The rotation of the first gear 26 will drive the second gear 27 meshing with it to rotate, thereby driving the rotating disk 9 to rotate through the connecting block 28, thereby realizing the disassembly of the tool handle 32. (Wherein, the connection groove is provided in order not to affect the tool during loading and unloading) By providing a small gear to drive the large gear to rotate, the space required can be reduced, thereby reducing the size of the equipment.

[0062] like Figure 6 As shown, preferably, a plurality of balls 29 are evenly arranged and rollingly connected on one side of the limit block 14 along the height direction, and the balls 29 are used in conjunction with the tool handle 32 .

[0063] Because the handle 32 is threadedly connected to the tool rod when the limit block 14 drives the handle 32 to rotate, the handle 32 will move downward when rotating. By providing a ball 29 to contact the handle 32, the contact area between the limit rod and the handle 32 can be reduced, thereby reducing friction, reducing losses, and extending the service life of the limit rod.

[0064] like Figure 7 As shown, preferably, a buffer layer 30 is provided at the bottom of the limiting block 14, and the material of the buffer layer 30 is rubber.

[0065] When the handle 4 is pulled downward, there is a probability that the bottom of the limit block 14 will directly contact the knife handle 32, thereby damaging the knife handle 32. By providing a rubber buffer layer 30 at the bottom of the limit block 14, the pressure can be absorbed and dispersed, thereby avoiding damage to the knife handle 32, thereby improving the overall processing efficiency.

[0066] like Figure 7 As shown, preferably, the two side surfaces of the limiting block 14 are provided with a wear-resistant layer 31 , and the material of the wear-resistant layer 31 is tungsten carbide.

[0067] By providing a wear-resistant layer 31 made of tungsten carbide on the surfaces of both sides of the limit block 14, the wear caused by friction between the limit block 14 and the tool handle 32 during operation can be reduced, thereby effectively extending the service life of the limit block 14 and improving the overall processing efficiency.

[0068] The working principle of this high-precision repeatable positioning combined CNC tool holder automatic loading and unloading equipment is explained in detail below.

[0069] like Figure 1 - Figure 7As shown, when the tool handle 32 needs to be disassembled, the tool rod is fixed by the clamping table on the workbench 1 (wherein, the workbench 1 and the clamping table are mature technologies in the prior art, so they are not described in detail in this article), and then the shell 2 is moved by the cooperation of the handle 4 and the control panel 5, so that the shell 2 is raised and lowered. When the shell 2 moves from top to bottom until the tool handle 32 enters the loading and unloading assembly, the power is transmitted to the loading and unloading assembly by the driving assembly, and the tool handle 32 is loaded and unloaded by the loading and unloading assembly. When tool handles 32 of different specifications need to be loaded and unloaded, the adjustment assembly is controlled by the control panel 5 to work, thereby adjusting the loading and unloading assembly so that the loading and unloading assembly can load and unload tool handles 32 of different specifications. The driving assembly driven by the drive motor 6 and the loading and unloading assembly can be used in combination to conveniently and quickly load and unload the tool handle 32, and the loading and unloading assembly can be quickly adjusted by the adjustment assembly so that the loading and unloading assembly can be quickly adapted to tool handles 32 of different specifications. When the tool handle 32 needs to be loaded and unloaded, the housing 2 is pulled downward by the handle 4 so that the limit block 14 fixedly connected under the slider is inserted into the keyway of the tool handle 32, and then the drive motor 6 is started. The drive motor 6 will transmit power to the rotating disk 9 through the drive assembly. At this time, the rotating disk 9 rotates relative to the housing 2. The rotation of the rotating disk 9 will drive the first slider 13 to revolve through the slide groove 11 and the screw rod 12, thereby driving the limit block 14 fixedly connected thereto to rotate. The rotation of the limit block 14 will drive the tool handle 32 to rotate through the keyway, thereby achieving the purpose of loading and unloading the tool handle 32. By setting the limit block 14 to be inserted into the tool handle 32 through the keyway and then rotating it, the effect of quickly loading and unloading the tool handle 32 can be achieved (wherein, the through groove 10 is provided so as not to affect the tool during loading and unloading). At the same time, the control panel 5 controls the drive motor 6 to drive the rotating disk 9 to rotate through the drive assembly to tighten the tool handle 32, so as to effectively control the loading and unloading accuracy of the tool handle 32.When it is necessary to load and unload tool handles 32 of different specifications, the second motor 8 is controlled by the control panel 5 to drive the rotating shaft 24 to rotate. Since the second slider 23 is slidably connected to the movable groove 22, the second slider 23 threadedly connected on the rotating shaft 24 will move toward each other along the direction of the axis of the rotating shaft 24. The movement of the second slider 23 will drive the first movable block 18 fixedly connected thereto to move. The through shaft 19 symmetrically arranged through the first movable block 18 and one side thereof is pressed against the through shaft 19 fixedly connected to one side of the second movable block 20, and then the second movable block 20 is pushed to move. The movement of the second movable block 20 will squeeze the pressure spring 21, and the pressure spring 21 is in a compressed state. At this time, the through shaft 19 fixedly connected to the first movable block 18 enters the second through groove 10 opened at one end of the screw rod 12 through the first through groove 10, and then the first motor 7 is controlled to rotate by the controller. The rotation of the first motor 7 will be The shaft body 15 drives the first movable block 18 slidably connected with the shaft body 15 to rotate, and the first movable block 18 will drive the screw rod 12 to rotate through the through shaft 19 and the second through hole 17 fixedly connected thereto. Because the first slider 13 is slidably connected with the slide groove 11, the rotation of the screw rod 12 will drive the first slider 13 threadedly connected thereto to move along the direction of the axis of the rotating shaft 24. The movement direction of the symmetrically arranged first sliders 13 is opposite. At this time, by adjusting the distance between the symmetrically arranged first sliders 13, the limit block 14 can be inserted into the keyway of the tool handle 32 of different specifications, so that the tool handle 32 of different specifications can be loaded and unloaded. When the adjustment is completed, the first motor 7 stops, and the second motor 8 is controlled to reverse. At this time, the second slider 23 will be reset, and the through shaft 19 fixedly connected with the first movable block 18 will be disengaged from the second through hole 17 and stop at the connection between the rotating disk 9 and the housing 2, and the pressure spring 21 will be reset. The weight reduction groove 25 is provided on the second movable block 20 to reduce the weight of the second movable block 20, thereby reducing the workload of the drive motor 6. When the handle 32 needs to be loaded and unloaded, the driving motor 6 is started through the control panel 5, and the driving motor 6 drives the first gear 26 fixedly connected to its output end to rotate. The rotation of the first gear 26 drives the second gear 27 meshing with it to rotate, thereby driving the rotating disk 9 to rotate through the connecting block 28, thereby realizing the disassembly of the handle 32. (Wherein, the connection groove is provided in order not to affect the tool during loading and unloading) By providing a small gear to drive the large gear to rotate, the space required can be reduced, thereby reducing the volume of the device. Because the handle 32 and the tool rod are threadedly connected when the limit block 14 drives the handle 32 to rotate, the handle 32 will move downward when rotating. By providing a ball 29 to contact the handle 32, the contact area between the limit rod and the handle 32 can be reduced, thereby reducing friction, reducing losses, and extending the service life of the limit rod.When the handle 4 is pulled downward, there is a probability that the bottom of the limit block 14 will directly contact the handle 32, thereby damaging the handle 32. By providing a rubber buffer layer 30 at the bottom of the limit block 14, the pressure can be absorbed and dispersed, thereby avoiding damage to the handle 32. By providing a wear-resistant layer 31 made of tungsten carbide on the surface of both sides of the limit block 14, the wear caused by friction between the limit block 14 and the handle 32 during operation can be reduced, thereby effectively extending the service life of the limit block 14.

[0070] 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.
