Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a CNC machine and its worktable installation method and storage medium. Background Technology

[0002] Computer Numerical Control machine tools (CNC) are common automated machining equipment. Because CNC equipment has a large machining area, when producing small workpieces, multiple workstations are set up on the CNC equipment's worktable. The workpiece material is placed in each workstation and then processed, thereby realizing the mass production of small workpieces.

[0003] However, the worktable is subjected to forces from different directions during production. To ensure machining accuracy, existing worktables are usually fixedly installed inside the CNC machine. After a batch is completed, due to the large size of the worktable, to ensure the safety of the workers, the CNC machine must be stopped and the machine door opened before the workers can perform unloading and loading operations on the worktable inside the CNC machine. This is not only inconvenient for workers to operate in a confined space, but also results in long loading and unloading times when there are many workpieces, leading to long standby times for the CNC machine and low production efficiency. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a CNC machine and its worktable installation method and storage medium, which enables rapid worktable replacement in the CNC machine, thereby achieving simultaneous loading / unloading and processing, and improving processing efficiency.

[0005] In a first aspect, embodiments of the present invention provide a CNC device, comprising:

[0006] The workbench includes a material loading section with multiple workstations. Each end of the material loading section has a connecting section with a first groove. The opening of the first groove faces the entrance side, which is the side near the equipment door of the CNC equipment.

[0007] A base, with a support portion on each side of the base, the support portion being used to support a workbench, and a first cylinder and a second cylinder being provided on the outer side of each support portion, the second cylinder being located on the inlet side of the first cylinder;

[0008] The first horizontal arm has a first protrusion at one end and is fixedly connected to the first cylinder at the other end. The first cylinder is used to drive the first horizontal arm to lift and lower.

[0009] The second horizontal arm has a second protrusion at one end and is fixedly connected to the second cylinder at the other end. A first column is provided on the lower side of the second protrusion. The second cylinder is used to drive the second horizontal arm to lift or rotate circumferentially.

[0010] When the worktable is in the locked state, the first protrusion and the second protrusion are pressed against the upper surface of the connecting part, and the first column is located within the first groove;

[0011] When the workbench is in the unlocked state, the first protrusion and the second protrusion are located on the upper side of the connecting part, and the first column is located outside the first groove.

[0012] According to some embodiments of the present invention, the workbench further includes:

[0013] The handle is located on the outside of the connecting part. When the worktable is in the locked state, the handle is located between the first cross arm and the second cross arm.

[0014] According to some embodiments of the present invention, the support portion is further provided with a second column and a second groove, the second groove being located on the inlet side of the second column, and a pressure sensor being connected to the bottom side of the second column; the bottom of the connecting portion is provided with a downward-opening third groove, and a baffle is provided in the bottom of the third groove;

[0015] When the workbench is placed on the support, the second column abuts against the baffle through the third groove;

[0016] When the workbench is in a locked state, the first column is inserted into the second groove.

[0017] According to some embodiments of the present invention, it further includes:

[0018] The upper surface of the first cylinder is provided with a first limiting part, and the upper surface of the second cylinder is provided with a second limiting part; the first cross arm is provided with a first limiting rod, and the second cross arm is provided with a second limiting rod, and the first limiting part and the second limiting part are lower than the upper surface of the support part;

[0019] When the worktable is in a locked state, the first limiting rod is located above or abuts against the first limiting part, and the second limiting rod is located above or abuts against the second limiting part.

[0020] Secondly, embodiments of the present invention also provide a method for installing a CNC machine's worktable, applied to a host computer of the CNC machine as described in the first aspect, the method comprising:

[0021] When the workbench is detected to be placed into the support section, a feeding signal is generated;

[0022] In response to the feeding signal, the second cylinder is controlled to drive the second horizontal arm to rotate circumferentially based on the target angle, so that the first column is inserted into the first groove from the inlet side. The first cylinder is controlled to drive the first horizontal arm to descend, and the second cylinder is controlled to drive the second horizontal arm to descend. When the first protrusion and the second protrusion are detected to press the connection part, it is determined that the worktable is switched to the locking state.

[0023] In response to the unloading signal, the first cylinder is controlled to drive the first horizontal arm to rise, and the second cylinder is controlled to drive the second horizontal arm to rise. Based on the target angle, the second cylinder is controlled to drive the second horizontal arm to rotate circumferentially so that the first column leaves the first groove. The worktable is then switched to the unlocked state. The unloading signal is generated after the CNC equipment completes the processing. After the second horizontal arm rises, the first column is located in the first groove.

[0024] According to some embodiments of the present invention, the support portion is further provided with a second column and a second groove, the second groove being located on the inlet side of the second column, and a pressure sensor being connected to the bottom side of the second column; the bottom of the connecting portion is provided with a downward-opening third groove, and a baffle is provided in the bottom of the third groove;

[0025] When the workbench is detected to be placed into the support section, a loading signal is generated, including:

[0026] Get the preset first duration and second duration;

[0027] When the real-time sensing value of the pressure sensor is detected to begin to decrease, a first sensing value is recorded, wherein the first sensing value is the real-time sensing value that remains unchanged within a first time period.

[0028] When the real-time sensing value of the pressure sensor is detected to start increasing based on the first sensing value, and a second sensing value is determined, the feeding signal is generated after a standby period of the second duration. The second sensing value is the real-time sensing value that remains unchanged during the first duration, and the second sensing value is greater than the first sensing value.

[0029] According to some embodiments of the present invention, after generating the feeding signal, the method further includes:

[0030] Record the second sensing value as the first reference value;

[0031] When a new second sensing value is obtained, and the difference between the new second sensing value and the first reference value is greater than a preset unit reference value, a first prompt message is generated, wherein the unit reference value is used to indicate the weight of a single workpiece, and the first prompt message is used to indicate that the loading part is missing the workpiece.

[0032] According to some embodiments of the present invention, after determining that the worktable has switched to the locking state, the method further includes:

[0033] Record the first height at which the first horizontal arm descends and the second height at which the second horizontal arm descends;

[0034] When the feeding signal is received, the first horizontal arm is controlled to rise based on the first height, and the second horizontal arm is controlled to rise based on the second height.

[0035] According to some embodiments of the present invention, after recording the first height of the first crossarm descent and the second height of the second crossarm descent, the method further includes:

[0036] Obtain a preset third height, wherein the third height is used to indicate the distance between the bottom of the first column and the opening of the second groove before the second cross arm descends;

[0037] When the second height is less than the third height, the downward pressure on the second protrusion is increased by the second cylinder.

[0038] Thirdly, embodiments of the present invention provide a computer-readable storage medium storing computer-executable instructions for performing the CNC equipment table mounting method as described in the second aspect above.

[0039] According to embodiments of the present invention, the CNC equipment and its worktable installation method and storage medium have at least the following beneficial effects: The worktable includes a loading section with multiple workstations. A connecting section is provided at each end of the loading section, and the connecting section has a first groove with its opening facing the entrance side, wherein the entrance side is the side closest to the equipment door of the CNC equipment; a base has a support section on each side of the base, the support section being used to support a worktable, and a first cylinder and a second cylinder are provided on the outer side of each support section, the second cylinder being located on the entrance side of the first cylinder; a first horizontal arm, the first... A first horizontal arm has a first protrusion at one end and is fixedly connected to a first cylinder at the other end. The first cylinder drives the first horizontal arm to lift and lower. A second horizontal arm has a second protrusion at one end and is fixedly connected to a second cylinder at the other end. A first column is provided on the lower side of the second protrusion. The second cylinder drives the second horizontal arm to lift and lower or rotate circumferentially. When the worktable is in the locked state, the first and second protrusions press against the upper surface of the connecting part, and the first column is located within a first groove. When the worktable is in the unlocked state, the first and second protrusions are located on the upper side of the connecting part, and the first column is located outside the first groove. According to the technical solution of this embodiment, the protrusions are used to achieve longitudinal locking and unlocking of the worktable, and the first column and the first groove are used to achieve transverse locking and unlocking of the worktable. Since the worktable is detachable, it is possible to have one worktable machining inside the CNC machine while another worktable is used for loading and unloading outside the CNC machine, providing a structural basis for improving the machining efficiency of the CNC machine.

[0052] This invention provides a CNC machine and its worktable installation method and storage medium. The CNC machine includes: a worktable, which includes a material-carrying section with multiple workstations. A connecting section is provided at each end of the material-carrying section, and each connecting section has a first groove with its opening facing the entrance side, wherein the entrance side is the side closest to the machine door of the CNC machine; a base, with a support section on each side of the base for supporting a worktable, and a first cylinder and a second cylinder on the outer side of each support section, the second cylinder being located at the entrance side of the first cylinder; a first crossarm, the first... One end of the cross arm is provided with a first protrusion, and the other end is fixedly connected to a first cylinder. The first cylinder is used to drive the first cross arm to rise and fall. A second cross arm is provided with a second protrusion at one end, and the other end is fixedly connected to a second cylinder. A first column is provided on the lower side of the second protrusion. The second cylinder is used to drive the second cross arm to rise and fall or rotate circumferentially. When the worktable is in the locked state, the first and second protrusions are pressed against the upper surface of the connecting part, and the first column is located within the first groove. When the worktable is in the unlocked state, the first and second protrusions are located on the upper side of the connecting part, and the first column is located outside the first groove. According to the technical solution of this embodiment of the invention, the protrusions are used to achieve longitudinal locking and unlocking of the worktable, and the first column and the first groove are used to achieve transverse locking and unlocking of the worktable. Since the worktable is detachable, it is possible to have one worktable for machining inside the CNC machine and another worktable for loading and unloading outside the CNC machine, providing a structural basis for improving the machining efficiency of the CNC machine.

[0053] First, such as Figures 1 to 3 As shown, this embodiment provides a CNC device, including:

[0054] The workbench 10 includes a material loading section 11, which is provided with multiple workstations 12. Each end of the material loading section 11 is provided with a connecting section 13, and the connecting section 13 is provided with a first groove 15. The opening of the first groove 15 faces the entrance side, wherein the entrance side is the side close to the equipment door of the CNC equipment.

[0055] The base 20 has a support part 23 on each side. The support part 23 is used to support a worktable 10. A first cylinder 211 and a second cylinder 221 are provided on the outer side of each support part 23. The second cylinder 221 is located on the inlet side of the first cylinder 211.

[0056] The first horizontal arm 212 has a first protrusion 213 at one end and is fixedly connected to the first cylinder 211 at the other end. The first cylinder 211 is used to drive the first horizontal arm 212 to rise and fall.

[0057] The second horizontal arm 222 has a second protrusion 223 at one end and is fixedly connected to the second cylinder 221 at the other end. A first column 224 is provided on the lower side of the second protrusion 223. The second cylinder 221 is used to drive the second horizontal arm 222 to lift or rotate in a circumferential direction.

[0058] When the workbench 10 is in the locked state, the first protrusion 213 and the second protrusion 223 are pressed against the upper surface of the connecting part 13, and the first column 224 is located within the first groove 15.

[0059] When the workbench 10 is in the unlocked state, the first protrusion 213 and the second protrusion 223 are located on the upper side of the connecting part 13, and the first column 224 is located outside the first groove 15.

[0060] It should be noted that the technical solution of this embodiment does not involve the improvement of CNC equipment processing-related components. For the sake of brevity, the processing components of the CNC equipment are omitted in the drawings, and only the part of the CNC equipment used to install the worktable 10 is shown. It will not be described again in the following.

[0061] It should be noted that, as Figures 1 to 3 As shown, the middle part of the workbench 10 is the material-carrying part 11, and the two sides are the connecting parts 13. The material-carrying part 11 is provided with multiple workstations 12. The workstations 12 are used to place the material-carrying part 11 and the connecting parts 13. They can be integrally formed or fixedly connected by related connecting structures. The stability of the material-carrying part 11 can be ensured when the connecting parts 13 are fixed.

[0062] It should be noted that CNC equipment is usually equipped with a door (not shown in the figure). During CNC equipment operation, the door is kept closed to ensure processing safety. After the CNC equipment completes processing and enters standby mode, the operator can open the door for loading and unloading, provided it is safe to do so. To facilitate the description of the positional relationships of the various structures, this embodiment uses the side where the door is located as the entrance side, such as... Figure 1 As shown, the worktable 10 can be drawn from... Figure 1 A CNC machine is placed at the entrance; the side where the entrance is located is called the entrance side. Figure 1 On the side corresponding to the bottom of the CNC machine, for example, the opening of the first groove 15 is in Figure 1 With the center facing down, when the worktable 10 is installed on the CNC equipment, the opening of the first groove 15 faces the equipment door of the CNC equipment, that is, as mentioned above, the opening of the first groove 15 faces the entrance side. Similarly, the second cylinder 221 is closer to the equipment door than the first cylinder 211. Therefore, the second cylinder 221 is located on the entrance side of the first cylinder 211. The definition of the entrance side will not be repeated hereafter.

[0063] It should be noted that the opening of the first groove 15 may be provided with a smooth chamfer, and the first column 224 is a structure that can rotate circumferentially along the longitudinal axis, that is, the first column 224 can be a rolling column. When the first column 224 rotates into the first groove 15, if the two come into contact, the first column 224 can roll along the contact surface with the first groove 15 to enter the first groove 15, thereby reducing the wear caused by friction between the first column 224 and the first groove 15 during the movement, and improving the service life of the above structure.

[0064] It should be noted that in this embodiment, a support portion 23 is provided on each side of the base 20, such as... Figure 3 As shown, the two support parts 23 jointly support both ends of the same worktable 10, thereby realizing the placement of the worktable 10. Of course, for the stability of the worktable 10, it can also be arranged as follows: Figure 3 As shown, multiple sets of support columns are set between the two support parts 23. No further limitations are made here, as long as they can achieve stable support for the workbench 10.

[0065] It is worth noting that this embodiment does not change the basic principle of machining through a single worktable 10 within the CNC equipment. In this embodiment, only one worktable 10 can still be placed inside the CNC equipment. However, the structure of this embodiment enables the worktable 10 to be detached. Compared to the existing technology of loading and unloading materials inside the CNC equipment, after the machining of the CNC equipment is completed, the worktable 10 can be removed from the CNC equipment, another loaded worktable 10 can be placed inside the CNC equipment, and then the CNC equipment can be started for machining. The worktable 10 outside the CNC equipment can be loaded and unloaded. The standby time of the CNC equipment is reduced to the time for picking up and placing the worktable 10, which can significantly reduce the standby time of the CNC equipment and improve machining efficiency.

[0066] It should be noted that, in order to make the workbench 10 detachable, this embodiment first sets a first cylinder 211 and a second cylinder 221 as power sources in the base 20. The first cylinder 211 and the second cylinder 221 can be the same model of cylinder or different models. In this embodiment, the first and second cylinders are used to distinguish the cylinders that have different actions during the installation process. The first cylinder 211 only needs to perform lifting and lowering, while the second cylinder 221 needs to perform lifting and lowering and circumferential rotation.

[0067] It should be noted that both the first cylinder 211 and the second cylinder 221 are equipped with longitudinally distributed drive shafts, such as... Figure 2 and Figure 3As shown, the first horizontal arm 212 is fixedly mounted on the drive shaft of the first cylinder 211, and the second horizontal arm 222 is fixedly mounted on the drive shaft of the second cylinder 221. Under the transmission action of the drive shaft, the first horizontal arm 212 and the second horizontal arm 222 are raised and lowered. At the same time, the second cylinder 221 can drive the drive shaft to drive, thereby driving the second horizontal arm 222 to achieve circumferential rotation.

[0068] It should be noted that the first horizontal arm 212 and the second horizontal arm 222 are as follows: Figure 1 As shown, the horizontal arrangement includes a first horizontal arm 212 extending from the first cylinder 211 to the upper side of the support 23, and a second horizontal arm 222 in the same manner. The lower side of the first horizontal arm 212 is provided with a first protrusion 213, and the lower side of the second horizontal arm 222 is provided with a second protrusion 223. The first protrusion 213 and the second protrusion 223 have different sizes. The lower side of the second protrusion 223 needs to be provided with a first column 224. The cross-section of the second protrusion 223 can be larger than that of the first protrusion 213. Since the connecting part 13 is usually kept horizontal after the worktable 10 is placed, the lower surfaces of the first protrusion 213 and the second protrusion 223 are flush, so that the first cylinder 211 and the second cylinder 221 can be raised and lowered at the same height, simplifying the control of the host computer. It can also ensure that after the first cylinder 211 and the second cylinder 221 are controlled to descend with the same parameters, the first protrusion 213 and the second protrusion 223 can simultaneously abut against the connecting part 13, improving the locking effect of the connecting part 13.

[0069] It should be noted that the position of the first column 224 can be adaptively adjusted according to the position of the first groove 15 in the worktable 10. For example, different models of second protrusions 223 can be set for different models of worktables 10, with each model of second protrusion 223 corresponding to a model of worktable 10. This allows the first column 224 to rotate into and out of the first groove 15 under the driving action of the second cylinder 221 after the second cross arm 222 is installed. Of course, in this embodiment, the circumferential rotation of the second cylinder 221 is performed first, so that the first column 224 is located in the first groove 15, and then the lowering operation is performed. The lowering operation cannot be performed first and then the rotation is performed, otherwise the second protrusion 223 will rotate while pressing the connecting part 13, resulting in unnecessary wear.

[0070] It should be noted that, driven by the second cylinder 221, the first column 224 can rotate circumferentially and be inserted from the side into the first groove 15 located on the inlet side, as shown below. Figure 1 As shown, Figure 1 The second cylinder 221 on the left drives the first column 224 to rotate counterclockwise to engage with the first groove 15 on the left, and the second cylinder 221 on the right drives the first column 224 to rotate clockwise to engage with the first groove 15 on the right. Figure 2 and Figure 3As shown, when the first column 224 is engaged in the first groove 15, by matching the dimensions of the first column 224 and the first groove 15, the lateral movement of the worktable 10 can be locked using the first column 224. Simultaneously, the lower surfaces of the first protrusion 213 and the second protrusion 223 are flush. The host computer can control the two first cylinders 211 and the two second cylinders 221 to raise and lower using the same height parameters. In this embodiment, by setting the height parameters, the first protrusion 213 and the second protrusion 223 can press against the upper surface of the connecting part 13 after the descent operation is completed. Since the connecting part 13 and the loading part 11 are rigidly connected, it is equivalent to the two sides of the loading part 11 being fixed by two sets of first protrusions 213 and second protrusions 223. Combined with the longitudinal locking of the first protrusions 213 and the second protrusions 223, the worktable 10 can be simultaneously locked inside the CNC machine from both longitudinal and lateral directions, ensuring the stability of the worktable 10 during CNC machining.

[0071] It should be noted that the first cylinder 211 and the second cylinder 221 can press the connecting part 13 by driving the first protrusion 213 and the second protrusion 223 down, or they can unlock the connecting part 13 by rising. Similarly, the first column 224 can rotate out of the first groove 15 according to the opposite rotation direction in the above embodiment, so that the worktable 10 is in the unlocked state. By using the cooperation of the cylinder, the horizontal arm, the protrusion and the first column 224, the worktable 10 can be detachably installed in the CNC equipment. With the detachable property of the worktable 10, the operator can configure at least two worktables 10. One worktable 10 is locked in the CNC equipment for processing, and the other worktable 10 is outside the CNC equipment for loading and unloading. After loading and unloading, wait for the CNC equipment to complete the processing. By changing the worktable 10 through the above structure, the time for changing the worktable 10 is greatly reduced compared to the time for loading and unloading, thereby reducing the downtime of the CNC equipment. In addition, loading and unloading outside the CNC equipment can also improve the convenience of operation and improve production efficiency.

[0072] Additionally, in one embodiment, reference is made to Figures 1 to 3 The workbench 10 also includes:

[0073] Handle 14 is located outside the connecting part 13. When the worktable 10 is locked, handle 14 is located between the first horizontal arm 212 and the second horizontal arm 222.

[0074] It should be noted that, according to the description of the above embodiments, the worktable 10 of this embodiment can be disassembled from the CNC equipment. In order to improve the convenience of picking up and putting down the worktable 10, a handle 14 is provided on the outside of the connecting part 13 in this embodiment. By adjusting the size and position of the handle 14, the handle 14 is located between the first cross arm 212 and the second cross arm 222 in the locked state.

[0075] It should be noted that in the unlocked state, the first protrusion 213 and the second protrusion 223 are located above the connecting part 13, which allows the worktable 10 to be lifted to a certain extent. At the same time, since the second horizontal arm 222 needs to drive the first column 224 to rotate out of the first groove 15, and the movement mode is circumferential rotation, the rotation angle can be set so that the first column 224 will inevitably not be aligned with the first groove 15 in the unlocked state. For example, if the rotation angle is set to 90 degrees, the second horizontal arm 222 will rotate from horizontal to vertical. Since the handle 14 is located between the first horizontal arm 212 and the second horizontal arm 222, and the second horizontal arm 222 is located on the entrance side, the operator can reach out from the equipment door to grab the handle 14 and remove the worktable 10 from the equipment door without interference from the second horizontal arm 222, and replace it with another worktable 10 that has been loaded.

[0076] Additionally, in one embodiment, such as Figure 4 and Figure 5 As shown, the support part 23 is also provided with a second column 232 and a second groove 231. The second groove 231 is located on the inlet side of the second column 232, and a pressure sensor is connected to the bottom side of the second column 232. The bottom of the connecting part 13 is provided with a downward-opening third groove 16, and a baffle 17 is provided in the bottom of the third groove 16.

[0077] When the workbench 10 is placed on the support 23, the second column 232 abuts against the baffle 17 through the third groove 16.

[0078] When the workbench 10 is in the locked state, the first column 224 is inserted into the second groove 231.

[0079] It should be noted that in this embodiment, a second column 232 is provided in the support portion 23. The second column 232 protrudes from the upper surface of the support portion 23, and a pressure sensor (not shown in the figure) is provided on the bottom side of the second column 232, so that the force applied to the upper side of the second column 232 can be detected by the pressure sensor. Figure 5 As shown, the bottom of the connecting part 13 is provided with a third groove 16, which is aligned with the second column 232. When the worktable 10 is placed in, the second column 232 is inserted into the third groove 16 and abuts against the baffle 17. Under the action of gravity, the baffle 17 applies pressure to the upper side of the second column 232, thereby triggering the pressure sensor to generate a reading.

[0080] It should be noted that the second column 232 has a second groove 231 on its inlet side. The second groove 231 opens to the upper side. When the worktable 10 is placed inside the CNC equipment, and the second cylinder 221 drives the first column 224 to insert into the first groove 15 from the side, the first column 224 is located on the upper side of the second groove 231. As the second cylinder 221 drives the second horizontal arm 222 to descend, the first column 224 is inserted into the second groove 231, thereby locking the first column 224 in the second groove 231 and improving stability.

[0081] Additionally, in one embodiment, such as Figure 2 and Figure 3 As shown, it also includes:

[0082] The upper surface of the first cylinder 211 is provided with a first limiting part, and the upper surface of the second cylinder 221 is provided with a second limiting part 226; the first cross arm 212 is provided with a first limiting rod 214, and the second cross arm 222 is provided with a second limiting rod 225. The first limiting part and the second limiting part 226 are lower than the upper surface of the support part 23.

[0083] When the worktable 10 is in the locked state, the first limiting rod 214 is located above or abuts against the first limiting part, and the second limiting rod 225 is located above or abuts against the second limiting part 226.

[0084] It should be noted that, as Figure 2 As shown, in this embodiment, a first limiting part (not shown in the figure) is provided on the upper surface of the first cylinder 211, and a second limiting part 226 is provided on the upper surface of the second cylinder 221. The first limiting part and the second limiting part 226 can be protruding structures and have arc-shaped upper surfaces so that they can abut against the corresponding limiting rods. When the first cross arm 212 and the second cross arm 222 have the same specifications, the first limiting part and the second limiting part 226 have the same shape and are vertically aligned. Of course, the positions can also be adjusted according to actual needs, and no further limitations are made here.

[0085] It should be noted that a first limiting rod 214 is provided on the lower side of the first cross arm 212, and a second limiting rod 225 is provided on the lower side of the second cross arm 222. The first limiting rod 214 is located between the first protrusion 213 and the first cylinder 211, and the second limiting rod 225 is located similarly. The lower surface of the first limiting rod 214 can be lower than the first protrusion 213, and the first limiting part is lower than the upper surface of the support part 23. When the first cylinder 211 drives the first limiting rod 214 to descend, if the worktable 10 is not placed, or the connecting part 13 of the worktable 10 is too low, the first limiting rod 214 will abut against the first limiting part before the first protrusion 213 abuts against the connecting part 13. This indicates that the current worktable 10 is not suitable, and the first protrusion 213 cannot lock the connecting part 13 when it reaches the lower limit of the first cylinder 211. This prompts the operator to check whether the worktable 10 is placed correctly or whether the first protrusion 213 of the correct specification is used, which can effectively improve the reliability of the locking of the worktable 10. The second limiting rod 225 and the second limiting part 226 are similar and will not be described again here.

[0086] In addition, this embodiment of the invention also provides a method for installing the worktable 10 of a CNC machine, which is applied to the host computer of the CNC machine as described above, such as... Figure 6 As shown, the method in this embodiment includes, but is not limited to, the following steps:

[0087] S10: When the worktable is detected to be placed into the support, a feeding signal is generated;

[0088] S20, in response to the feeding signal, based on the target angle, control the second cylinder to drive the second horizontal arm to rotate circumferentially so that the first column is inserted into the first groove from the inlet side, control the first cylinder to drive the first horizontal arm to descend, control the second cylinder to drive the second horizontal arm to descend, and when the first protrusion and the second protrusion are detected to press the connection part, determine that the worktable is switched to the locking state.

[0089] S30, in response to the unloading signal, controls the first cylinder to drive the first horizontal arm to rise, controls the second cylinder to drive the second horizontal arm to rise, controls the second cylinder to drive the second horizontal arm to rotate circumferentially based on the target angle, so that the first column leaves the first groove, and determines that the worktable switches to the unlocked state. The unloading signal is generated after the CNC equipment completes the processing. After the second horizontal arm rises, the first column is located in the first groove.

[0090] It should be noted that this embodiment is applied to a host computer, which can be electrically connected to the first cylinder 211 and the second cylinder 221, thereby controlling the operation of the first cylinder 211 and the second cylinder 221 according to the set control logic and parameters.

[0091] It should be noted that, according to the principle described in the above structural embodiment, when the worktable 10 is detected to be placed in the support part 23, the worktable 10 in the CNC equipment is filled with the raw material to be processed. The loading signal generated by the host computer is used to trigger the first cylinder 211 and the second cylinder 221 to drive the relevant components to lock the worktable 10.

[0092] It should be noted that after receiving the feeding signal, according to the description of the above structural embodiment, as follows: Figures 1 to 3 As shown, it is necessary to first control the two second cylinders 221 to rotate circumferentially so that the two first pillars 224 are each locked into the corresponding first groove 15. In this embodiment, the target angle is preset in the host computer so that after the second cylinders 221 rotate to the target angle, the first pillars 224 can be locked into the first groove 15. After rotating in the opposite direction according to the target angle, the first pillars 224 can be located outside the first groove 15 and do not interfere with the movement of the handle 14, which is convenient for changing the worktable 10.

[0093] For example, such as Figure 1 and Figure 2 As shown, the target angle can be set to 90 degrees. Figure 2 Taking the first column 224 shown on the left as an example, before receiving the feeding signal, the second horizontal arm 222 is positioned towards the entrance side. After the operator places the workbench 10 into the CNC equipment and generates the feeding signal, the host computer controls the second cylinder 221 to rotate 90 degrees counterclockwise, causing the first column 224 to engage with the first groove 15 of the workbench 10. Figure 2 The same applies to the first column 224 on the right, except that the direction of rotation is opposite, counterclockwise. The rotation of the second cylinders 221 on both sides is mirrored. Further details will not be repeated here.

[0094] It should be noted that after the first column 224 is engaged in the first groove 15, the lower surfaces of the first protrusion 213 and the second protrusion 223 in this embodiment are aligned to ensure control consistency. At this time, the host computer simultaneously sends a descent command to the first cylinder 211 and the second cylinder 221, and the two cylinders descend at the same height, so that the first protrusion 213 and the second protrusion 223 simultaneously press the connecting part 13. After the above operation is completed, the host computer can determine that the worktable 10 has been switched to the locking state and control the CNC equipment to perform the relevant processing. The specific processing process is not within the scope of discussion in this embodiment.

[0095] It should be noted that after the CNC equipment completes machining, it automatically generates a feeding signal. After the host computer detects the feeding signal, it performs the opposite operation to step S20. First, it controls the first cylinder 211 and the second cylinder 221 to rise, and then controls the second cylinder 221 to rotate circumferentially. The rotation angle is the same as the target angle, but the direction is opposite to that in step S20, as in the example above. Figure 2If the first column 224 on the left side rotates counterclockwise into the first groove 15, then in step S30 it rotates clockwise out of the first groove 15, which will not be repeated here. After the second cylinder 221 has finished rotating out, the host computer can determine that the worktable 10 is in the unlocked state to perform subsequent operations. For example, subsequent operations may include unlocking the equipment door, allowing the operator to open the door and replace it with another worktable 10 that has been loaded with materials.

[0096] Additionally, in one embodiment, reference is made to Figure 4 and Figure 5 Step S10 specifically includes, but is not limited to, the following steps:

[0097] S11, obtain the preset first duration and second duration;

[0098] S12, when the real-time sensing value of the pressure sensor starts to decrease, the first sensing value is recorded, wherein the first sensing value is the real-time sensing value that remains unchanged within the first time period.

[0099] S13, when the real-time sensing value of the pressure sensor is detected to start increasing based on the first sensing value, and after the second sensing value is determined, a feeding signal is generated after a second standby time, wherein the second sensing value is the real-time sensing value that remains unchanged during the first time, and the second sensing value is greater than the first sensing value.

[0100] It should be noted that, according to the description of the above structural embodiment, the support part 23 is provided with a second column 232 and a pressure sensor. In this embodiment, the reading of the pressure sensor is used to determine whether loading and unloading are completed, thereby automatically identifying whether the workbench 10 has been replaced.

[0101] It should be noted that in this embodiment, the host computer presets a first time period. When the real-time sensing value of the pressure sensor begins to decrease, it can be determined that the load on the support 23 is being removed. This process is usually quite fast, so the value of the pressure sensor will change rapidly. For example, the reading may drop rapidly from the actual weight of the workbench 10 to a smaller value, such as the weight of the second column 232. When the real-time sensing value is detected to remain unchanged for a certain period of time, it can be recorded as the first sensing value. The first sensing value is the reading of the pressure sensor when the support 23 is unloaded.

[0102] For example, the workbench 10 is typically heavy. After the worker removes the workbench 10, it needs to be placed in a specific location to prepare for unloading, and another workbench 10 with material loaded is placed into the CNC machine. The time difference during this period can be used as the first duration, for example, the first duration is set to 10 seconds. When the real-time sensing value drops to a small value and remains unchanged within 10 seconds, it can be determined that the workbench 10 has been moved out, and the current reading is recorded as the first sensing value. Even if the workbench 10 is lifted and then put back in for other reasons, since the duration of the first sensing value is insufficient and the real-time sensing value does not continuously decrease, this embodiment introduces two judgment conditions: continuous decrease and maintenance of the first duration. This can avoid triggering the loading signal by the same workbench 10 that has already been processed, avoid performing the locking operation twice on the same workbench 10, and ensure the reliability of production.

[0103] It should be noted that when the pressure sensor records the first sensing value, it can be determined that the workbench 10 has been removed. In this embodiment, the workbench 10 is not considered placed back simply because an increase in the real-time sensing value is detected. Instead, the recording of the second sensing value is only triggered when the real-time sensing value is detected to be increasing from the first sensing value, after the first sensing value has been successfully recorded. This ensures that a new workbench 10 is placed back in only after the first workbench 10 has been completely removed. The principle of the second sensing value is similar to that of the first sensing value and will not be repeated here. This embodiment uses a first duration as the duration of the judgment based on the increase or decrease of the real-time sensing value to determine the placement or removal of the workbench 10, thereby achieving automatic judgment of the installation status of the workbench 10 and improving the degree of automation.

[0104] It should be noted that after the second sensor value is determined, the worker may have just placed the device into the workbench 10. In this embodiment, the loading signal is generated after a delay based on the second duration. For example, the second duration is set to 15 seconds. After the worker places the device into the workbench 10, he will leave the CNC equipment. The loading signal is generated 15 seconds later to trigger the closing of the equipment door and the rotation of the second cylinder 221, which can ensure the safety of personnel.

[0105] In another embodiment, after generating the feeding signal in step S10, the method further includes, but is not limited to, the following steps:

[0106] S14, record the second sensing value as the first reference value;

[0107] S15, when a new second sensing value is obtained, and the difference between the new second sensing value and the first reference value is greater than a preset unit reference value, a first prompt message is generated, wherein the unit reference value is used to indicate the weight of a single workpiece 30, and the first prompt message is used to indicate that the loading part is short of workpieces.

[0108] It should be noted that after obtaining the second sensor value, it is recorded as the first reference value. CNC equipment typically produces a large number of products, and the workpieces placed on the worktables in multiple batches are identical. Therefore, the weight of each workpiece placed on the worktable should be the same or within a certain error range. In this embodiment, the host computer presets the weight of a workpiece as a unit reference value. When a new second sensor value is obtained, if the difference between it and the first reference value is greater than the unit reference value, it can be determined that the two placed workpieces differ by at least one, and a first prompt message is generated due to the difference in quantity.

[0109] It should be noted that after receiving the first prompt, staff can respond manually. For example, if it is confirmed that no workpiece has been missed, the staff can manually trigger the loading signal on the host computer, or control the CNC equipment to standby on the host computer and re-place the workpiece on the worktable. No further restrictions will be made here.

[0110] In another embodiment, after determining that the worktable has switched to the locked state in step S20, the following steps are included, but are not limited to:

[0111] S21, record the first height of the first horizontal arm descending and the second height of the second horizontal arm descending;

[0112] S22, when the unloading signal is obtained, the first horizontal arm is controlled to rise based on the first height, and the second horizontal arm is controlled to rise based on the second height.

[0113] It should be noted that, referring to Figure 2 and Figure 3 In this embodiment, the first height and the second height are recorded after each descent. According to the description of the above embodiment, the lower surfaces of the first protrusion 213 and the second protrusion 223 are flush, and the descent height of the two is the same. Therefore, the values ​​of the first height and the second height can be the same.

[0114] It should be noted that since the first cylinder 211 and the second cylinder 221 can descend to the first height and the second height, it can be determined that the height before descent will not affect the picking and placing of the worktable 10. When the unloading signal is obtained, in order to raise the first horizontal arm 212 and the second horizontal arm 222 without affecting the picking and placing of the worktable 10, this embodiment uses the first height and the second height as the rising height parameters to ensure that the first horizontal arm 212 and the second horizontal arm 222 rise to a position suitable for the picking and placing of the worktable 10.

[0115] Additionally, in one embodiment, reference is made to Figure 4 and Figure 5 After step S21 is completed, the following steps are included, but are not limited to:

[0116] S211, obtain a preset third height, wherein the third height is used to indicate the distance between the bottom of the first column and the opening of the second groove before the second cross arm descends;

[0117] S212, when the second height is less than the third height, the downward pressure of the second protrusion is increased by the second cylinder.

[0118] It should be noted that, referring to Figure 2 and Figure 3 In this embodiment, a third height is set in the host computer. The third height is the distance between the bottom of the first column 224 and the second groove 231 before the second horizontal arm 222 descends. According to the description of the above embodiment, the second cylinder 221 first drives the first column 224 to rotate into the first groove 15 and fix it from the side. When the second height is less than the third height, it can be determined that after the second protrusion 223 abuts against the connecting part 13, the first column 224 fails to insert into the second groove 231. Without the connection and cooperation of the first column 224 and the second groove 231, the lateral support force is reduced to a certain extent. Therefore, in this embodiment, the second cylinder 221 increases the downward pressure of the second protrusion 223, and the longitudinal force is increased to compensate for the decrease in lateral support force, thus ensuring the stability of the worktable 10.
