[0021] like Figure 1-3As shown, this embodiment provides a vacuum adsorption device, which includes: a cylinder 201, a vacuum suction cup 210 and a vacuum suction cup mounting device 100; the vacuum suction cup mounting device 100 includes: a support seat 110, a connecting member 120, a connecting component 130, a first limiting member 140, and a second limiting member 150. The support seat 110 is provided with a plurality of air holes 160; the air holes 160 are used to provide blowing and suction, that is, to facilitate the start and close of the vacuum suction cup and the cylinder; the connecting piece 120 is used for the installation of the vacuum suction cup 210 and the cylinder 201, and a connecting port 170 is provided on the connecting piece 120, one end of the connecting port 170 is used to communicate with the vacuum suction cup 210 or the cylinder; the connecting piece 120 can be fixedly installed with the support seat 110; the connecting component 130 is installed on the support seat 110, one end of the connecting component 130 is communicated with the air holes 160, and the other end of the connecting component 130 is communicated with the other end of the communicating port 170; that is, the connecting piece 120 is used for the installation of the vacuum suction cup 210 and the support seat 110, and the first limiting member 140 is installed on the support seat 110, and is used The connecting member 120 is installed with a limiter; the second limiter 150 is installed on the support seat 110, and is used for aligning and limiting the connecting port 170 on the connecting member 120 with the connecting component 130; wherein, the height of the first limiter 140 is higher than the height of the second limiter 150, and the height of the second limiter 150 is higher than the height of the connecting component 130. When the connecting member 120 is installed with the support seat 110, the connecting member 120 first contacts with the first limiter 140 for limiting, and then contacts with the second limiter 150 for limiting; after the connecting member 120 contacts with the second limiter 150 and is limited, the connecting component 130 is aligned with the connecting port 170 and installed and sealed. That is to say, the vacuum suction cup 210 is first installed on one side of the connecting member 120, and the other side of the connecting member 120 is then installed on the support seat 110; when the connecting member 120 and the support seat 110 are installed, the connecting member 120 first contacts with the first limiting member 140, and the first limiting member 140 performs preliminary limiting on the connecting member 120, and then the connecting member 120 contacts with the second limiting member 150, and the second limiting member 150 limits the connecting member 120 again, and the second limiting means aligning the connecting component 130 with the connecting port 170 to prevent the large offset of the connecting member 120 during installation from causing the connecting member 120 to be difficult to install on the support seat 110, resulting in its correction being more difficult; when the connecting member 120 is installed on the support seat 110 through the limiting member, the connecting component 130 on the support seat 110 is sealed and connected with the connecting port 170 on the connecting member 120. The connecting port 170 is connected to the air hole 160 after limiting the position first, so as to ensure that the vent 170 on the connecting piece 120 and the connecting component 130 on the supporting seat 110 are installed in alignment, that is, the connecting piece 120 is prevented from being skewed, resulting in the airtightness of the vent pipe and the connecting component 130 being loose, and the operator does not need to repeat the connection operation.

[0022] like Figure 2 As shown, in this embodiment, the first limiting member 140 is a limiting plate; there are multiple limiting plates, and the multiple limiting plates are fixedly installed on the four sides of the support seat 110 respectively, and the inner side of one end of the limiting plate away from the support seat 110 is chamfered; when the connecting member 120 is moved to the support seat 110 for installation, the connecting member 120 slides between the multiple limiting plates through the chamfer of the limiting plate, so that the connecting member 120 completes the limited installation. In other words, when the connecting member 120 is installed to the support seat 110, the limiting plate is chamfered to move the connecting member 120 to the inner side of the multiple limiting plates. At this time, there is a gap between the limiting plate and the connecting member 120, so that when the connecting member 120 moves to the support seat 110, the connecting member 120 will not be stuck with the limiting plate due to the contact between the connecting member 120 and the limiting plate, and it will be difficult to continue to move to the support seat 110 for installation.

[0023] like Figure 2 As shown, in this embodiment, the second limiting member 150 is a limiting rod, and the number of limiting rods is multiple, and the end of the limiting rod away from the support seat 110 is tapered; the connecting member 120 is provided with multiple through holes 121. When the connecting member 120 is moved toward the support seat 110 for installation, the limiting rod slides into the through hole 121 on the connecting member 120 through the tapered end, so that the connecting member 120 is aligned. In other words, when the connecting member 120 is installed to the support seat 110, the tapered end of the limiting rod first enters the through hole 121 until the through hole 121 is completely covered on the limiting rod, and the limiting rod through the through hole 121 makes the positioning of the connecting member 120 more stable, which can prevent the connecting member 120 from being misaligned, resulting in the problem that the connecting member 120 is deflected and the airtightness of the vent 170 and the connecting component 130 is not strict.

[0024] like Figure 2 and Fig.14 As shown, in this embodiment, the connecting component 130 includes a mounting tube 131 and a sealing member 132; the sealing member 132 is an elastic sealing ring, and the mounting tube 131 is fixedly mounted on the support seat 110; the sealing member 132 is sleeved on one end of the mounting tube 131 away from the support seat 110. When the connecting member 120 is mounted on the support seat 110, the mounting tube 131 is sealed and connected to the connecting port 170 through the sealing member 132. That is, after the connecting member 120 is limited by the second limiting member 150, the connecting port 170 is sleeved on the mounting tube 131, and the sealing ring is used to seal between the mounting tube 131 and the connecting port 170; and when the connecting port 170 is sleeved on the mounting tube 131, the connecting port 170 first squeezes the sealing ring to deform, and after the sealing ring is deformed, the connecting port 170 is sleeved outside the mounting tube 131. Since the sealing ring is squeezed and deformed, the contact between the sealing ring and the mounting tube 131 and the connecting port 170 is closer, so that the sealing effect is better.

[0025] like Figure 15-16As shown, in this embodiment, the vacuum adsorption device 100 also includes a clamping assembly 300; the clamping assembly includes a ring 301, a swing rod 302, a first spring 303, a second spring 304 and a clearance groove 305 provided on the second limiter 150; the ring 301 and the first spring 303 are sleeved on the second limiter 150, and the first spring 303 is located between the ring 301 and the support seat 110; each clearance groove 305 is equipped with two swing rods 302, and the swing rod 302 rotates close to the side of the support seat 110 The adjacent sides of the two rocking rods 302 are respectively fixedly mounted on one end of the second spring 304; the elastic force of the second spring 304 is greater than the elastic force of the first spring 303; when the first spring 303 pushes the ring 301 to the side away from the support seat 110, the ring 301 can be sleeved on the outside of the clearance groove 305, and the ring 301 prevents the rocking rod 302 from swinging outward; when the ring 301 pushes toward the support seat 110, the ring 301 separates from the clearance groove 305, and the second spring 304 pushes the rocking rod 302 to swing outward. That is to say, when the second limiting component 150 is inserted into the through hole 121, the connecting piece 120 first contacts the ring 301, the ring 301 disengages from the making way groove 305, and the rocker arm 302 located in the making way groove 305 moves into the through hole 121 until it passes through the through hole 121. After the rocker arm 302 passes through the through hole 121, the rocker arm 302 swings outward under the action of the second spring 304. When the rocker arm 302 swings outward, it will generate a pressing force that causes the connecting piece 120 to the support seat 110, which can ensure that the connecting piece 120 can be moved to the corresponding position during installation, that is, the connecting component 130 can be placed in the connecting port 170 for tight sealing, to prevent the connecting piece 120 from not moving downward completely, resulting in poor sealing and air leakage. When the connecting member 120 is separated from the supporting seat 110, the connecting member 120 gradually separates from the second limiting assembly 150 and squeezes the rocker arm 302 to move into the clearance groove 305. At the same time, the first spring 303 pushes the ring 301 to move with the connecting member 120. When the ring 301 moves to the outside of the clearance groove 305, the first spring 303 stops pushing the ring 301 to move with the connecting member 120, and the ring 301 blocks the rocker arm 302 from swinging outward, which facilitates the next installation of the connecting member 120.

[0026] In this embodiment, the vacuum adsorption device 100 further includes a fixing assembly 220; the fixing assembly 220 is used to fix the support seat 110 and the connecting member 120. That is, after the connecting member 120 is installed with the support seat 110 via the first stopper 140 and the second stopper 150, the support seat 110 and the connecting member 120 are fixed via the fixing member to prevent shaking during the processing.

[0027] like Figure 4-7As shown, in one embodiment, there are multiple fixing components 220, and each fixing component 220 includes a first fixing sleeve 221, a first positioning block 222, a first positioning hole 223, and a vent 224 provided on the first fixing sleeve 221. A connecting hole 226 is provided on the support seat, and the connecting hole 226 is connected to one of the air holes 160; there is more than or equal to one first positioning block 222 on each fixing component 220, and when there are multiple first positioning blocks 222, they can move inward or outward at the same time. The first fixing sleeve 221 is installed on the support seat 110, the first positioning block 222 is installed on the first fixing sleeve 221, and the vent 224 is connected to the connecting hole 226 on the support seat 110; the first positioning hole 223 is provided on the connecting member 120; a first card slot 225 is provided in the first positioning hole 223, and when the connecting member 120 is installed on the support seat 110, the first fixing sleeve 221 moves into the first positioning hole 223, and the air is filled into the first fixing sleeve 221 through the vent 226 and the vent 224. The first positioning block 222 moves into the first positioning hole 223, and the first positioning block 222 moves into the first slot 225, so that the connecting member 120 is fixed to the support seat 110; when the connecting member 120 is separated from the support seat 110, air is extracted from the first fixing sleeve 221 through the vent hole 226 and the vent 224, the first positioning block 222 moves into the first fixing sleeve 221, and the first positioning block 222 is separated from the first slot 225, so that the connecting member 120 is separated from the support seat 110. When the connecting member 120 is moved toward the support seat 110, the end of the first fixing sleeve 221 on the support seat 110 is placed in the first positioning hole 223 on the connecting member 120, and the limiting installation of the connecting member 120 and the support seat 110 is completed. After the limiting installation is completed, the corresponding air hole 160 on the support seat 110 is activated to allow gas to be filled into the first fixing sleeve 221, and the air pressure in the first fixing sleeve 221 increases. Then, the air pressure pushes the movable first positioning block 222 to move outward, and the outer end of the first positioning block 222 moves into the first slot 225 to make the connecting member 120 and the support seat 110 move outward. The connecting member 120 is fixed to the support seat 110 to complete the fixed installation of the connecting member 120 and the support seat 110; when the connecting member 120 needs to be separated from the support seat 110, the corresponding air hole 160 on the support seat 110 is activated to allow the gas in the first fixed sleeve 221 to be extracted, and a negative pressure is formed in the fixed sleeve. Then, the negative pressure causes the movable first positioning block 222 to move inward, and the outer end of the first positioning block 222 is separated from the first slot 225, so that the connecting member 120 and the support seat 110 are not fixed, and the separation of the connecting member 120 and the support seat 110 is completed.

[0028] like Figure 8-13As shown, in another embodiment, there are multiple fixing components 220, and each fixing component 220 includes a second fixing sleeve 321, a second positioning block 322, a second positioning hole 323, a second round rod 324, and a spiral plate 325 installed on the round rod 324. There is more than or equal to one second positioning block 322 on each fixing component 220. When there are multiple second positioning blocks 322, the spiral plate 325 can make them move inward or outward at the same time. The second fixing sleeve 321 is installed on the support seat 110, and the second positioning block 322 is installed on the second fixing sleeve 321; the second positioning hole 323 is provided on the connecting member 120, and a second slot 327 is provided in the second positioning hole 323; the round rod 324 is installed on the second fixing sleeve 321, and the round rod 324 is driven by the forward and reverse motor 326; when the connecting member 120 is installed with the supporting seat 110, the second fixing sleeve 321 moves into the second positioning hole 323, and the forward and reverse motor 326 rotates to drive the round rod 324 to rotate, and the round rod 324 is driven by the spiral plate 325. The rotary plate 325 drives the second positioning block 322 to move into the second positioning hole 323, and the second positioning block 322 moves into the second slot 327, so that the connecting member 120 is fixed to the support seat 110; when the connecting member 120 is separated from the support seat 110, the forward and reverse motor 326 rotates in the opposite direction to drive the second positioning block 322 to rotate, so that the spiral plate 325 drives the second positioning block 322 to move into the second fixing sleeve 321, the second positioning block 322 is separated from the second slot 327, and the connecting member 120 is separated from the support seat 110. When the connecting member 120 moves toward the support seat 110, the end of the second fixing sleeve 321 on the support seat 110 is placed in the second positioning hole 323 on the connecting member 120, and the limiting installation of the connecting member 120 and the support seat 110 is completed. After the limiting installation is completed, the forward and reverse motor 326 is started, and the forward and reverse motor 326 drives the round rod 324 and the spiral plate 325 on the round rod 324 to rotate, and the spiral plate 325 pushes the movable second positioning block 322 to move outward, and the outer end of the second positioning block 322 moves into the second slot 327 so that the connecting member 120 It is fixed to the support base 110 to complete the fixed installation of the connecting member 120 and the support base 110; when the connecting member 120 needs to be separated from the support base 110, the forward and reverse motor 326 is started to rotate in the reverse direction, and the forward and reverse motor 326 drives the round rod 324 and the spiral plate 325 on the round rod 324 to rotate in the reverse direction, and then the spiral plate 325 drives the movable second positioning block 322 to move inward, and the outer end of the second positioning block 322 is separated from the slot, so that the connecting member 120 and the support base 110 are not fixed, and the separation of the connecting member 120 and the support base 110 is completed.

[0029] like Fig.13As shown, in another embodiment, the spiral center line of the spiral plate 325 is a flat spiral line; the second positioning block 322 is provided with two inner and outer clamping blocks 328 on one side close to the spiral plate 325, which are respectively clamped on the inner and outer sides of the spiral plate 325. When the spiral plate 325 rotates with the round rod 324, the spiral plate 325 pushes the second positioning block 322 to move outward or inward through the clamping block 328.

[0030] like Figure 2 As shown, in this embodiment, the vacuum suction cup installation device further includes a support member 180, and the number of the support members 180 is multiple; the support member 180 is installed on the support seat 110; when the connecting member 120 is installed with the support seat 110, the support member 180 stops the connecting member 120 from moving downward. That is, after the connecting member 120 moves toward the support seat 110, the support member 180 stops the connecting member 120 from moving toward the support seat 110, so that a gap is left between the support seat 110 and the connecting member 120, so that the connection between the connecting member 120 and the support seat 110 is easy to observe, and at the same time, the multiple support members 180 can also play a role in stabilizing the supporting function of the connecting member 120.

[0031] like Figure 1-2 As shown, in this embodiment, the vacuum suction cup installation device 100 further includes a mounting frame 190; the mounting frame 190 is mounted on the side of the connecting member 120 away from the support seat 110, and the vacuum suction cup 210 is mounted on the mounting frame 190; the cylinder 201 is mounted on the connecting member 120, and the cylinder 201 presses the vacuum suction cup 210 against the mounting frame 190. The vacuum suction cup 210 and the connecting member 120 are connected via the mounting frame 190, which facilitates the connection between the vacuum suction cup 210 and the connecting port 170, and the cylinder 201 is used for pressing to prevent the vacuum suction cup 210 from leaking from the side during the vacuum adsorption operation, resulting in incomplete adsorption of the workpiece, which in turn leads to errors in processing.

[0032] like Figure 1-2 As shown, in this embodiment, there are multiple cylinders 201, and the cylinders 201 are located on the peripheral side of the mounting frame 190; a clamping block 202 is provided on the cylinder 201, the middle part of the clamping block 202 is hinged to the end cover of the cylinder 201 through a connecting rod, and one end of the clamping block 202 is hinged to the end of the piston rod of the cylinder 201. The cooperation between the cylinder 201 and the clamping block 202 can directly use internal air supply to achieve clamping, and there is no need to connect an external electrical component to the connector 120 to fix the vacuum suction cup 210, which prevents the problem of difficulty in disassembly and assembly caused by the electrical component; similarly, there is no need for the operator to clamp, which avoids the problem of insufficient clamping force during the operation of the operator.

[0033] In this embodiment, a pipeline connected to the communication port 170 is provided on the mounting frame 190, so that after the vacuum suction cup 210 is placed on the mounting frame 190, the vacuum suction cup 210 can operate when suction is started.

[0034] This embodiment provides a machine tool, including a machine tool body and a vacuum adsorption device for the machine tool; the support base of the vacuum adsorption device is fixedly installed with the machine tool body. That is, when in use, the support base 110 is fixed on the machine tool, and the connecting member 120 can be separated from the machine tool, so as to facilitate the replacement of the connecting member.

[0035] In summary, the present invention provides a vacuum adsorption device and a machine tool. By making the first limit member higher than the second limit member, and the second limit member higher than the connecting component, the connecting component and the support seat can be accurately installed during installation; at the same time, it can also ensure that the connecting component and the connecting port are accurately aligned, so that the connecting component and the connecting port are installed and well sealed, reducing the repeated installation of the ventilation pipeline in the later stage, and the operation is more convenient and accurate.
