Description

Technical Field

[0001] The present invention relates to the technical field of high-end equipment manufacturing, and particularly relates to a vacuum adsorption device and a machine tool. Background Art

[0002] When processing thin plate components, vacuum adsorption is mostly used for processing. After multiple uses, debris and oil stains will appear on the vacuum suction cup and the mounting bracket, and they need to be replaced in time.

[0003] The existing replacement method of the vacuum suction cup device is as follows. First, align the vacuum suction cup with the mounting seat. The existing alignment methods mostly use the way of straightening, and straightening requires the operator to observe. It is very difficult to distinguish when there are slight errors, which will affect the later processing accuracy to a certain extent; after the installation is completed, the operator also needs to connect the air pipe to the vacuum suction cup or the air supply device one by one. When there are many air pipes to be installed, it will bring a certain burden to the operator, and at the same time, the problem of misconnecting the interfaces will also occur. Summary of the Invention

[0004] Aiming at the deficiencies in the existing installation, the purpose of the present invention is to provide a vacuum adsorption device and a machine tool that are easy to install.

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a vacuum adsorption device, including: a cylinder, a vacuum suction cup, and a vacuum suction cup mounting device; the vacuum suction cup mounting device includes:

[0007] A support seat provided with a plurality of air holes;

[0008] A connecting piece for installing the vacuum suction cup and the cylinder. The connecting piece is provided with a communication port, and one end of the communication port is used to communicate with the vacuum suction cup and the cylinder; the connecting piece can be fixedly installed with the support seat;

[0009] A communication component installed on the support seat. One end of the communication component is communicated with the air hole, and the other end of the communication component is communicated with the other end of the communication port;

[0010] A first limiting piece installed on the support seat for limiting the installation of the connecting piece;

[0011] A second limiting piece installed on the support seat for aligning and limiting the communication port on the connecting piece and the communication component;

[0012] Among them, the height of the first limiting member is higher than that of the second limiting member, and the height of the second limiting member is higher than that of the communication component. When the connecting member is installed on the support base, the connecting member first contacts the first limiting member for limiting, and then the connecting member contacts the second limiting member for limiting. After the connecting member contacts and is limited by the second limiting member, the communication component is aligned and sealed with the communication port.

[0013] In some embodiments, the first limiting member is a limiting plate; there are multiple limiting plates, and the multiple limiting plates are respectively fixedly installed around the support base, and the inner side of the end of the limiting plate away from the support base is chamfered;

[0014] When the connecting member moves towards the support base for installation, the connecting member slides between the multiple limiting plates through the chamfer of the limiting plate, so that the connecting member completes the limiting installation.

[0015] In some embodiments, the second limiting member is a limiting rod, the number of the limiting rods is multiple, and the end of the limiting rod close to the connecting member is conical;

[0016] Multiple through holes are provided on the connecting member;

[0017] When the connecting member moves towards the support base for installation, the limiting rod slides into the through hole on the connecting member through the conical end, so that the connecting member is aligned.

[0018] In some embodiments, the communication component includes an installation pipe and a sealing member;

[0019] The installation pipe is fixedly installed with the support base; one end of the installation pipe is communicated with the air hole, and the sealing member is sleeved on the end of the installation pipe away from the support base;

[0020] When the connecting member is installed on the support base, the other end of the installation pipe is hermetically connected to the communication port through the sealing member.

[0024] Two swing rods are rotatably arranged in each relief groove, and the adjacent sides of the two swing rods are respectively fixedly installed with one end of the second spring;

[0025] The elastic force of the second spring is greater than the elastic force of the first spring;

[0026] When the first spring pushes the ring to the side away from the support seat, the ring can be sleeved on the outside of the clearance groove, and the ring prevents the swing rod from swinging outward; when the ring pushes toward the support seat, the ring separates from the clearance groove, and the second spring pushes the swing rod to swing outward.

[0027] In some embodiments, the vacuum adsorption device further includes a fixing component;

[0028] The fixing assembly is used to fix the supporting seat and the connecting member.

[0031] The first fixing sleeve is installed on the supporting seat, and the first positioning block is installed on the first fixing sleeve;

[0032] The first positioning hole is provided on the connecting member;

[0033] When the connecting member is installed with the support seat, the first fixing sleeve is moved into the first positioning hole, air is inflated into the first fixing sleeve through the connecting hole and the air vent, and the first positioning block moves into the first positioning hole to fix the connecting member with the support seat; when the connecting member is separated from the support seat, air is extracted from the first fixing sleeve through the connecting hole and the air vent, and the first positioning block moves into the first fixing sleeve to separate the connecting member from the support seat.

[0034] In some embodiments, there are multiple fixing assemblies, each of which includes a second fixing sleeve, a second positioning block, a second positioning hole, a round rod, and a spiral plate installed on the round rod;

[0036] The second positioning hole is provided on the connecting member;

[0037] The round rod is installed on the second fixing sleeve, and the round rod is driven to rotate by the forward and reverse motor;

[0038] When the connecting member is installed on the support seat, the second fixing sleeve moves into the second positioning hole. The forward and reverse motor rotates to drive the round rod to rotate. The round rod drives the second positioning block to move into the second positioning hole through the spiral plate, so that the connecting member is fixed to the support seat. When separating the connecting member from the support seat, the forward and reverse motor rotates in the reverse direction to drive the second positioning block to rotate, so that the spiral plate drives the second positioning block to move into the second fixing sleeve, and the connecting member is separated from the support seat.

[0039] In some embodiments, the vacuum chuck mounting device further includes a mounting bracket;

[0040] The mounting bracket is installed on a side of the connecting member away from the support seat, and the vacuum chuck is installed on the mounting bracket;

[0070] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0071] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0072] For the convenience of describing the first direction, the second direction, and the third direction in the embodiments of the present application, the first direction is the left - right direction in the accompanying drawings, the second direction is the front - back direction in the accompanying drawings, and the third direction is the up - down direction in the accompanying drawings. Among them, the direction of the x - axis arrow is used as the "right" direction in the following text, the direction of the y - axis arrow is used as the "up" direction in the following text, and the direction of the z - axis arrow is used as the "back" direction in the following text. In the actual application of the present application, this is not limited thereto.

[0073] Such as Figures 1-3As shown in the figure, 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 piece 120, a connecting component 130, a first limiting piece 140, and a second limiting piece 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 stop 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 communication port 170 is provided on the connecting piece 120, and one end of the communication 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 hole 160, and the other end of the connecting component 130 is communicated with the other end of the communication port 170; that is, the connecting piece 120 is used for the installation of the vacuum suction cup 210 and the support seat 110, the first limiting piece 140 is installed on the support seat 110 for the installation limit of the connecting piece 120; the second limiting piece 150 is installed on the support seat 110 for the alignment limit of the communication port 170 on the connecting piece 120 and the connecting component 130; wherein, the height of the first limiting piece 140 is higher than the height of the second limiting piece 150, and the height of the second limiting piece 150 is higher than the height of the connecting component 130. When the connecting piece 120 is installed with the support seat 110, the connecting piece 120 first contacts the first limiting piece 140 for limiting, and then the connecting piece 120 contacts the second limiting piece 150 for limiting; after the connecting piece 120 contacts the second limiting piece 150 and is limited, the connecting component 130 and the communication port 170 are aligned and sealed. That is to say, the vacuum suction cup 210 is first installed on one side of the connecting piece 120, and the other side of the connecting piece 120 is then installed on the support seat 110; when the connecting piece 120 is installed with the support seat 110, the connecting piece 120 first contacts the first limiting piece 140, and the first limiting piece 140 performs preliminary limiting on the connecting piece 120. After that, the connecting piece 120 contacts the second limiting piece 150 again, and the second limiting piece 150 performs secondary limiting on the connecting piece 120. The secondary limiting is to align the connecting component 130 and the communication port 170, preventing large deviation of the connecting piece 120 during installation from making it difficult to install the connecting piece 120 on the support seat 110 and making its correction difficult; when the connecting piece 120 is installed on the support seat 110 through the limiting piece, the connecting component 130 on the support seat 110 is hermetically connected to the communication port 170 on the connecting piece 120. By first limiting and then connecting the communication port 170 and the air hole 160, it is ensured that the ventilation port 170 on the connecting piece 120 is aligned and installed with the connecting component 130 on the support seat 110, that is, the problem of airtightness not being strict between the ventilation pipe and the connecting component 130 caused by the skew of the connecting piece 120 is prevented, and there is no need for the operator to repeat the operation of connection.

[0074] As Figure 2 shown, in this embodiment, the first limiting member 140 is a limiting plate; there are multiple limiting plates, and the multiple limiting plates are respectively fixedly installed around the support base 110, and the inner side of the end of the limiting plate away from the support base 110 is chamfered; when the connecting member 120 moves towards the support base 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 limiting installation. That is to say, when the connecting member 120 is installed towards the support base 110, the limiting plate moves the connecting member 120 to the inner side of the multiple limiting plates through the chamfer. At this time, there is a gap between the limiting plate and the connecting member 120, so that when the connecting member 120 moves towards the support base 110, it will not happen that the connecting member 120 and the limiting plate are stuck due to contact between the connecting member 120 and the limiting plate, and it is difficult to continue moving towards the support base 110 for installation.

[0075] As Figure 2 shown, in this embodiment, the second limiting member 150 is a limiting rod, the number of limiting rods is multiple, and the end of the limiting rod away from the support base 110 is conical; there are multiple through holes 121 on the connecting member 120. When the connecting member 120 moves towards the support base 110 for installation, the limiting rod slides into the through holes 121 on the connecting member 120 through the conical end, so that the connecting member 120 is aligned. That is to say, when the connecting member 120 is installed towards the support base 110, the conical end of the limiting rod first enters the through hole 121 until the through hole 121 completely sleeves on the limiting rod. The limiting rod makes the positioning of the connecting member 120 more stable through the through hole 121, and can prevent the connecting member 120 from being misaligned, resulting in the problem that the air vent 170 and the connecting component 130 are not airtight due to the skew of the connecting member 120.

[0076] As Figure 2 and Figure 14 shown, in this embodiment, the connecting component 130 includes an installation pipe 131 and a sealing member 132; the sealing member 132 is an elastic sealing ring, and the installation pipe 131 is fixedly installed with the support base 110; the sealing member 132 is sleeved on the end of the installation pipe 131 away from the support base 110. When the connecting member 120 is installed with the support base 110, the installation pipe 131 is hermetically connected to the communication port 170 through the sealing member 132. That is, after the connecting member 120 is limited by the second limiting member 150, the communication port 170 sleeves on the installation pipe 131, and a sealing ring is used for sealing between the installation pipe 131 and the communication port 170; when the communication port 170 sleeves on the installation pipe 131, the communication port 170 first squeezes the sealing ring to deform. After the sealing ring deforms, the communication port 170 sleeves outside the installation pipe 131. Since the contact between the sealing ring and the installation pipe 131 and the communication port 170 is closer after the sealing ring is squeezed and deformed, its sealing effect is better.

[0077] As Figures 15-16As shown, in this embodiment, the vacuum adsorption device 100 further includes a pressing component 300; the pressing component includes a ring 301, a swing rod 302, a first spring 303, a second spring 304, and a relief groove 305 provided in the second limiting member 150; the ring 301 and the first spring 303 are sleeved on the second limiting member 150, and the first spring 303 is located between the ring 301 and the support base 110; two swing rods 302 are installed in each relief groove 305, and the swing rods 302 are rotatably connected to the side close to the support base 110, and the adjacent sides of the two swing rods 302 are respectively fixedly installed with 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 away from the support base 110, the ring 301 can be sleeved outside the relief groove 305, and the ring 301 prevents the swing rod 302 from swinging outwards; when the ring 301 is pushed towards the support base 110, the ring 301 is separated from the relief groove 305, and the second spring 304 pushes the swing rod 302 to swing outwards. That is to say, when the second limiting component 150 is inserted into the through hole 121, the connecting member 120 first contacts the ring 301, the ring 301 is separated from the relief groove 305, and the swing rod 302 located in the relief groove 305 moves into the through hole 121 until it passes through the through hole 121. When the swing rod 302 passes through the through hole 121, the swing rod 302 swings outwards under the action of the second spring 304. When the swing rod 302 swings outwards, a pressing force that makes the connecting member 120 press towards the support base 110 will be generated, which can ensure that the connecting member 120 can move to the corresponding position during installation, that is, the connecting component 130 can be placed in the communication port 170 for tight sealing, preventing the problem of air leakage caused by incomplete downward movement of the connecting member 120 resulting in poor sealing. When separating the connecting member 120 from the support base 110, the connecting member 120 gradually separates from the second limiting component 150 and squeezes the swing rod 302 to move into the relief groove 305. At the same time, the first spring 303 will push the ring 301 to move with the connecting member 120; when the ring 301 moves outside the relief groove 305, the first spring 303 stops pushing the ring 301 to move with the connecting member 120, and the ring 301 blocks the swing rod 302 from swinging outwards, facilitating the installation of the connecting member 120 next time.

[0078] In this embodiment, the vacuum adsorption device 100 further includes a fixing component 220; the fixing component 220 is used for fixing the support base 110 and the connecting member 120. That is to say, after the connecting member 120 is installed on the support base 110 through the first limiting member 140 and the second limiting member 150, the support base 110 and the connecting member 120 are fixed by fixing parts to prevent shaking during the processing.

[0079] As Figures 4-7As shown, in one embodiment, there are multiple fixing components 220. Each fixing component 220 includes a first fixing sleeve 221, a first positioning block 222, a first positioning hole 223, and a vent hole 224 provided on the first fixing sleeve 221. A communication hole 226 is provided on the support base, and the communication hole 226 communicates with one of the air holes 160; the number of the first positioning blocks 222 on each fixing component 220 is greater than or equal to one, and when there are multiple ones, they can move inward or outward simultaneously. The first fixing sleeve 221 is installed on the support base 110, the first positioning block 222 is installed on the first fixing sleeve 221, and the vent hole 224 communicates with the communication hole 226 on the support base 110; the first positioning hole 223 is provided on the connecting member 120; a first clamping groove 225 is provided in the first positioning hole 223. When the connecting member 120 is installed on the support base 110, the first fixing sleeve 221 is moved into the first positioning hole 223, and air is inflated into the first fixing sleeve 221 through the vent hole 226 and the vent hole 224. The first positioning block 222 moves into the first positioning hole 223, and the first positioning block 222 moves into the first clamping groove 225 to fix the connecting member 120 to the support base 110; when separating the connecting member 120 from the support base 110, air is pumped out of the first fixing sleeve 221 through the vent hole 226 and the vent hole 224. The first positioning block 222 moves into the first fixing sleeve 221, and the first positioning block 222 is separated from the first clamping groove 225 to separate the connecting member 120 from the support base 110. When the connecting member 120 moves towards the support base 110, the end of the first fixing sleeve 221 on the support base 110 is placed in the first positioning hole 223 on the connecting member 120 to complete the limit installation of the connecting member 120 and the support base 110. After the limit installation is completed, the corresponding air hole 160 on the support base 110 is activated to allow gas to be inflated into the first fixing sleeve 221. 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 clamping groove 225 to fix the connecting member 120 to the support base 110, completing the fixed installation of the connecting member 120 and the support base 110; when it is necessary to separate the connecting member 120 from the support base 110, the corresponding air hole 160 on the support base 110 is activated to pump out the gas in the first fixing sleeve 221, creating a negative pressure in the fixing 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 clamping groove 225, making the connecting member 120 not fixed to the support base 110, completing the separation of the connecting member 120 from the support base 110.

[0080] As Figures 8-13As shown, in another embodiment, there are multiple fixing components 220. 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 mounted on the round rod 324. The number of second positioning blocks 322 on each fixing component 220 is greater than or equal to one. When there are multiple second positioning blocks 322, the spiral plate 325 can make them move inward or outward simultaneously. The second fixing sleeve 321 is mounted on the support base 110, and the second positioning block 322 is mounted on the second fixing sleeve 321; the second positioning hole 323 is provided on the connecting member 120, and a second card slot 327 is provided in the second positioning hole 323; the round rod 324 is mounted on the second fixing sleeve 321 and is driven by a forward and reverse motor 326; when the connecting member 120 is mounted to the support base 110, the second fixing sleeve 321 is moved into the second positioning hole 323, and the forward and reverse motor 326 rotates to drive the round rod 324 to rotate. The round rod 324 drives the second positioning block 322 to move into the second positioning hole 323 through the spiral plate 325, and the second positioning block 322 moves into the second card slot 327 to fix the connecting member 120 to the support base 110; when separating the connecting member 120 from the support base 110, the forward and reverse motor 326 rotates in the reverse 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, and the second positioning block 322 is separated from the second card slot 327, and the connecting member 120 is separated from the support base 110. When the connecting member 120 moves towards the support base 110, the end of the second fixing sleeve 321 on the support base 110 is placed in the second positioning hole 323 on the connecting member 120 to complete the limit installation of the connecting member 120 and the support base 110. After the limit installation is completed, the forward and reverse motor 326 is started. The forward and reverse motor 326 drives the round rod 324 and the spiral plate 325 on the round rod 324 to rotate. 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 card slot 327 to fix the connecting member 120 to the support base 110, completing 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. 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. 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 card slot, making the connecting member 120 and the support base 110 unfixed, completing the separation of the connecting member 120 and the support base 110.

[0081] As Figure 13As shown, in another embodiment, the spiral center line of the spiral plate 325 is a flat spiral line; there are two inner and outer clamping blocks 328 on one side of the second positioning block 322 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.

[0082] As Figure 2 shown, in this embodiment, the vacuum suction cup mounting device further includes a support member 180, and the number of the support members 180 is multiple; the support members 180 are mounted on the support seat 110; when the connecting member 120 is mounted on the support seat 110, the support members 180 stop the connecting member 120 from continuing to move downward. That is, when the connecting member 120 moves towards the support seat 110, the support members 180 stop the connecting member 120 from moving towards the support seat 110, leaving a gap between the support seat 110 and the connecting member 120, which is convenient for observing the connection situation between the connecting member 120 and the support seat 110. At the same time, the multiple support members 180 can also play a role in stably supporting the connecting member 120.

[0083] As Figures 1-2 shown, in this embodiment, the vacuum suction cup mounting 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 connection between the vacuum suction cup 210 and the connecting member 120 through the mounting frame 190 is convenient for the connection between the vacuum suction cup 210 and the communication port 170. Also, the cylinder 201 is used for pressing to prevent air leakage from the side of the vacuum suction cup 210 during the vacuum adsorption operation, resulting in incomplete adsorption of the workpiece and easy errors during processing.

[0084] As Figures 1-2 shown, in this embodiment, there are multiple cylinders 201, and the cylinders 201 are located on the periphery of the mounting frame 190; there is a pressing block 202 on the cylinder 201. The middle of the pressing block 202 is hinged to the end cover of the cylinder 201 through a connecting rod, and one end of the pressing block 202 is hinged to the end of the piston rod of the cylinder 201. The cooperation of the cylinder 201 and the pressing block 202 can directly achieve pressing by internal air supply, without the need to externally connect electrical components on the connecting member 120 to fix the vacuum suction cup 210, thus preventing the problem of difficult disassembly and assembly caused by electrical components; similarly, there is no need for the operator to press, avoiding the problem of insufficient pressing force during the operator's operation.

[0085] In this embodiment, the mounting frame 190 is provided with a pipeline connected to the communication port 170, so that after the vacuum suction cup 210 is placed on the mounting frame 190, the vacuum suction cup 210 can operate when starting to suck air.

[0086] This embodiment provides a machine tool, including a machine tool main body and a vacuum adsorption device for the machine tool; the support base of the vacuum adsorption device is fixedly installed on the machine tool main body. That is to say, during use, the support base 110 is fixed on the machine tool, and the connecting member 120 can be separated from the machine tool, facilitating the replacement of the connecting member.

[0087] In summary, the present invention provides a vacuum adsorption device and a machine tool. By having the first limiting member higher than the second limiting member and the second limiting member higher than the connecting assembly, when the connecting member is installed, the precise installation of the connecting member and the support base can be ensured; at the same time, the precise alignment of the connecting assembly and the connecting port can also be ensured, enabling the connecting assembly and the connecting port to be aligned and installed with good sealing, reducing the repeated installation of the ventilation pipeline in the later stage, and making the operation more convenient and accurate.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
