Description

Technical Field

[0001] The present invention relates to the technical field of machine tool processing, and particularly relates to a machine tool electromagnetic clamping mechanism. Background Art

[0002] A magnetic chuck refers to a chuck that adsorbs ferromagnetic objects through magnetic force. Electromagnetic chucks are widely used for fixing workpieces during processing. When processing a workpiece, the workpiece needs to be placed on the electromagnetic chuck. The electromagnetic chuck is energized to generate magnetic force to fix the workpiece, so as to facilitate processing techniques such as milling of the workpiece.

[0003] The existing Chinese patent with the publication number "CN221495189U" and the name "An electromagnetic chuck and processing equipment" introduces an electromagnetic chuck, including an electromagnetic chuck body. The electromagnetic chuck body has a support surface for supporting the workpiece. An air passage is provided on the electromagnetic chuck body, and the air passage extends to the support surface to form an airtight test port on the support surface. If there are impurities between the workpiece and the support surface, it will affect the sealing condition of the airtight test port, and it can be concluded that the support surface needs to be cleaned or the bottom surface of the workpiece is uneven, so as to avoid the situation of inaccurate processing accuracy caused by the unevenness of the workpiece as early as possible.

[0004] The above-mentioned existing technology has the following technical defects: The airtight test port on the support surface can only test one placement surface of the workpiece. Generally, a workpiece has two placement surfaces. If the above-mentioned existing technology discards the workpiece when the airtightness of one placement surface of the workpiece is not met, it will cause waste of the workpiece. And if the workpiece is flipped, the operation of flipping the workpiece is not only more troublesome, but also when flipping the workpiece, the placement surface of the workpiece may be scratched. Summary of the Invention

A driving wheel corresponding to the conveying wheel is provided on the output shaft of the driving motor. The conveying wheel and the driving wheel are sleeved with the same driving belt. The driving motor can drive the conveying wheel to rotate through the driving belt, and thereby drive the conveying roller to rotate.

[0011] Furthermore, the classification mechanism includes a carrying plate and a partition plate. The carrying plate is arranged on the mounting frame and can receive the workpiece conveyed by the conveying roller. The partition plate is arranged on the carrying plate. The partition plate divides the mounting frame into a middle area, a left flat area and a right flat area.

[0012] Further, a grid frame is arranged inside the electromagnetic frame. The grids of the grid frame are arranged as electromagnetic mounting holes, and the electromagnetic suction blocks are arranged in the electromagnetic mounting holes.

[0013] Further, an airtight compensation groove is arranged inside the grid frame. The airtight compensation groove includes a grid groove and a straight groove.

Detailed implementation manners

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection" and "coupling" mentioned in the present invention, unless otherwise specified, both include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0031] In the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0032] Such as Figure 1 and Figure 2As shown in the figure, an electromagnetic clamping mechanism for a machine tool provided by an embodiment of the present invention includes a base 100, a sorting mechanism 200, and a conveying mechanism 300. Among them, an electromagnetic frame 400 and a mounting frame 500 are installed on the base 100. An electromagnetic chuck 401 is arranged inside the electromagnetic frame 400, and the electromagnetic chuck 401 can be used to fix the workpiece. Two sets of detection mechanisms are arranged on the mounting frame 500. The two sets of detection mechanisms are respectively corresponding to the two placement surfaces of the workpiece, and can simultaneously perform airtightness detection on the corresponding placement surfaces. The sorting mechanism 200 is arranged on the mounting frame 500, and the sorting mechanism 200 is used to sort the workpieces that meet the airtightness requirements, and more intuitively show the workpieces that can be tightened by the electromagnetic chuck 401. The conveying mechanism 300 is arranged on the mounting frame 500, and the conveying mechanism 300 is used to convey the workpiece to the detection mechanism and the sorting mechanism 200.

[0033] Specifically, the present invention can be arranged inside the machine tool. The base 100 can be a flat plate installed inside the machine tool. The mounting frame 500 can be a frame body that is symmetrically installed on the base 100 from left to right. The mounting frame 500 can be a "U"-shaped frame body. The mounting frame 500 can include two side plates and a bottom plate, and the two side plates are respectively fixed on both sides of the bottom plate. The two sets of detection mechanisms are both arranged on the mounting frame 500, and can be respectively arranged on the two side plates of the mounting frame 500. The two sets of detection mechanisms respectively correspond to the two placement surfaces of the workpiece to be processed, and can simultaneously perform airtightness detection on the corresponding workpiece placement surfaces. The conveying mechanism 300 is arranged between the bottom plate and the side plate of the mounting frame 500 and is used for the movement of the workpiece on the mounting frame 500. The sorting mechanism 200 can be arranged inside the mounting frame 500 and can receive the workpieces that meet the airtightness requirements and are conveyed by the conveying mechanism 300 and detected by the detection mechanism.

[0034] It should be noted that the present invention is applicable to various machine tools that can fix workpieces by electromagnetic force, including but not limited to surface grinders, gantry milling machines, gantry planers, etc. The workpieces mentioned in the present invention are standard cube workpieces or cuboid workpieces, and each of them includes at least two opposite placement surfaces. After performing airtightness detection on the placement surfaces of the workpiece and sorting the workpiece, the workpieces that meet the airtightness requirements can be placed on the electromagnetic chuck 401 manually or mechanically, and the placement surface of the workpiece that meets the airtightness requirements is brought into contact with the electromagnetic chuck 401, thereby completing the placement of the workpiece on the electromagnetic chuck 401.

[0035] When performing airtightness detection on the workpiece in this embodiment, first place the workpiece to be detected on the mounting rack 500. The conveying mechanism 300 can convey the workpiece to the position of the detection mechanism. Then, the two groups of detection mechanisms respectively perform airtightness detection on the two placement surfaces of the workpiece. After the airtightness detection of the two placement surfaces of the workpiece is completed, the conveying mechanism 300 can convey the detected workpiece to the sorting mechanism 200. The sorting mechanism 200 can sort the workpieces that meet the airtightness requirements, and can more intuitively show which side placement surface of the workpiece meets the airtightness requirements, making it more convenient to place the workpieces that meet the airtightness requirements on the electromagnetic suction block 401 in the electromagnetic frame 400.

[0036] In some embodiments, the two groups of detection mechanisms are respectively arranged on both sides of the mounting rack 500 and are symmetrically arranged with respect to the mounting rack 500. The detection mechanisms arranged on both sides of the mounting rack 500 can simultaneously perform airtightness detection on the two placement surfaces of the workpiece, and thus can more quickly determine the workpieces that meet the airtightness requirements and can more quickly put the workpieces that meet the airtightness requirements into production.

[0037] The detection mechanism includes a fixed frame 510. The fixed frame 510 is fixed on one side of the mounting rack 500. A detection cylinder 511 and a clamping cylinder 512 are installed on the fixed frame 510. The detection cylinder 511 is located on the side of the clamping cylinder 512 away from the mounting rack 500. A pressure gauge capable of detecting the pressure in its cylinder body is arranged on the detection cylinder 511. One end of the output shaft of the detection cylinder 511 is connected to a moving frame 5111. The end of the moving frame 5111 away from the detection cylinder 511 can extend into the mounting rack 500 and is connected to a first mounting plate 5112. The output shaft of the clamping cylinder 512 penetrates through the first mounting plate 5112 and can extend into the mounting rack 500. A second mounting plate 5121 is connected to the output shaft of the clamping cylinder 512. The first mounting plate 5112 and the second mounting plate 5121 are arranged opposite to each other and are parallel to each other. A piston rod 5113 is arranged on the side of the first mounting plate 5112 facing the second mounting plate 5121. A piston cylinder 5122 adapted to the piston rod 5113 is arranged on the side of the second mounting plate 5121 facing the first mounting plate 5112. One end of the piston cylinder 5122 away from the first mounting plate 5112 penetrates to the side surface of the second mounting plate 5121 away from the first mounting plate 5112. The workpiece is located between the two second mounting plates 5121 corresponding to the two groups of detection mechanisms, and the two placement surfaces of the workpiece are respectively in close contact with the second mounting plates 5121 on its two sides.

[0038] According to the position of the output shaft of the detection cylinder 511 relative to the cylinder body of the detection cylinder 511 and the change of the pressure gauge, it can be judged whether the two placement surfaces of the workpiece meet the airtightness requirements.

[0039] Specifically, the fixing frame 510 can be a "mesh"-shaped frame perpendicular to the side plate of the mounting frame 500, and the frame surface of the "mesh"-shaped frame is parallel to the bottom plate of the mounting frame 500. The detection cylinder 511 and the clamping cylinder 512 can be respectively arranged on the cross bars 412 spaced apart on the fixing frame 510, wherein the clamping cylinder 512 is closer to the mounting frame 500 than the detection cylinder 511. Both the detection cylinder 511 and the clamping cylinder 512 can be rod-type air cylinders or rod-type hydraulic cylinders. A pressure gauge can be installed on the cylinder body of the detection cylinder 511, and the pressure gauge can directly detect the pressure inside the detection cylinder 511. The moving frame 5111 is a frame fixed on the output shaft of the detection cylinder 511. The moving frame 5111 can include a bottom plate and four connecting rods. The bottom plate can be a square plate. One side of the bottom plate is fixed to one end of the output shaft of the detection cylinder 511. The four connecting rods are all fixed to one side of the bottom plate and are respectively close to the four end corners of the bottom plate. The four connecting rods of the moving frame 5111 can surround the clamping cylinder 512 and can extend into the mounting frame 500. The four connecting rods of the moving frame 5111 extending into the mounting frame 500 can be fixedly connected to the first mounting plate 5112. The first mounting plate 5112 can be a plate parallel to the placement surface of the workpiece.

[0040] The clamping cylinder 512 can be directly arranged on the cross bar 412 of the fixing frame 510 closest to the mounting frame 500. The end of the output shaft of the clamping cylinder 512 away from its cylinder body directly extends into the mounting frame 500 and can penetrate through the first mounting plate 5112 located in the mounting frame 500, and then is fixedly connected to the second mounting plate 5121. When the output shaft of the clamping cylinder 512 penetrates through the first mounting plate 5112, a through hole can be formed on the first mounting plate 5112. The side wall of the output shaft of the clamping cylinder 512 can be in contact with the inner wall of the through hole and can slide along the axial direction of the through hole. The second mounting plate 5121 is parallel to the first mounting plate 5112. When the clamping cylinder 512 operates, the second mounting plate 5121 can move towards the workpiece under the drive of the output shaft of the clamping cylinder 512.

[0041] A plurality of piston rods 5113 can be provided. The plurality of piston rods 5113 are evenly distributed on the side surface of the first mounting plate 5112 facing the second mounting plate 5121. A plurality of piston barrels 5122 are also provided. Each piston barrel 5122 corresponds to one piston rod 5113. The inner diameter of the inner barrel of the piston barrel 5122 is the same as the size of the piston body of the piston rod 5113. The piston rod 5113 can be inserted into the piston barrel 5122 and its piston body is hermetically fitted with the inner wall of the piston barrel 5122. When the second mounting plate 5121 is stationary and the first mounting plate 5112 approaches the second mounting plate 5121 under the drive of the detection cylinder 511, the piston rod 5113 can be inserted into the corresponding piston barrel 5122.

[0042] When the detection mechanism does not perform an airtightness detection on the placement surface of the workpiece, the second mounting plates 5121 on both sides of the mounting frame 500 can clamp the workpiece in the central position between the side plates on both sides of the mounting frame 500. The piston rod 5113 can be inserted into the corresponding piston cylinder 5122 and can abut against the corresponding second mounting plate 5121.

[0043] When the detection mechanism performs an airtightness detection on the placement surface of the workpiece, the detection cylinder 511 will drive the first mounting plate 5112 to move away from the second mounting plate 5121 through the moving frame 5111. As a result, the first mounting plate 5112 can drive the piston rod 5113 to move in the corresponding piston cylinder 5122. By the distance that the piston rod 5113 moves in the piston cylinder 5122 and the change of the pressure gauge on the detection cylinder 511, it can be determined whether the placement surfaces on both sides of the workpiece meet the airtightness requirements.

[0044] The operating principle of this embodiment is as follows:

[0045] First, before detecting the workpiece, a preset pressure value A needs to be set for the pressure gauge, and a preset distance B needs to be set for the distance that the piston rod 5113 moves in the corresponding piston cylinder 5122.

[0046] After determining the preset pressure value A and the preset distance B, the detection of the workpiece begins. The detection process of the workpiece is as follows:

[0047] The workpiece to be detected is conveyed by the conveying mechanism 300 between the two detection mechanisms of the mounting frame 500, so that the placement surfaces on both sides of the workpiece face both sides of the mounting frame and are respectively between the two corresponding second mounting plates 5121 of the two detection mechanisms. When the workpiece to be detected is conveyed between the two corresponding second mounting plates 5121, the conveying of the workpiece by the conveying mechanism 300 is stopped. Then, the clamping cylinder 512 and the detection cylinder 511 are started. The clamping cylinder 512 pushes the second mounting plate 5121 close to the placement surface of the workpiece to be detected and gradually adheres tightly to the placement surface of the workpiece to be detected. The detection cylinder 511 pushes the first mounting plate 5112 close to the second mounting plate 5121 through the moving frame 5111. The piston rod 5113 can move in the piston cylinder 5122 and gradually abuts against the second mounting plate 5121. When the second mounting plate 5121 clamps the workpiece to be detected in the central position of the mounting frame 500 and the piston rods 5113 all abut against the second mounting plate 5121 on the corresponding side, the clamping and positioning of the workpiece to be detected are completed. At this time, the values of the pressure gauges on the detection cylinders 511 on both sides of the mounting frame 500 should be equal.

[0048] After that, the detection cylinders 511 on both sides of the mounting bracket 500 are controlled to drive the moving bracket 5111 to move towards the side away from the corresponding second mounting plate 5121. The moving bracket 5111 drives the first mounting plate 5112 to move, and the first mounting plate 5112 drives the piston rod 5113 to move in the piston cylinder 5122. The piston rod 5113 slides in the piston cylinder 5122 in the direction away from the corresponding second mounting plate 5121. When the distance that the piston rod 5113 moves in the piston cylinder 5122 reaches the preset distance B, the detection ends. Record the pressure values in the pressure gauges on both sides of the mounting bracket 500 at this time and compare them with the preset pressure value A, so as to determine whether the two placement surfaces of the workpiece meet the airtightness requirements of the present invention.

[0049] Suppose the two placement surfaces of the workpiece are surface D and surface E respectively. Surface D is smooth and flat, and the flatness of surface E is less than that of surface D. When the distances that the piston rods 5113 corresponding to surface D and surface E of the workpiece move in the piston cylinders 5122 both reach the preset distance B, since the flatness of surface D is greater than that of surface E, therefore, the suction force of the piston cylinder 5122 corresponding to surface D of the workpiece on surface D of the workpiece is greater than the suction force of the piston cylinder 5122 corresponding to surface E of the workpiece on surface E of the workpiece. That is to say, when the piston rod 5113 on the side of surface D of the workpiece moves the preset distance B in the piston cylinder 5122, it needs to overcome a greater force. At this time, the detection cylinder 511 on the side of surface D of the workpiece needs to provide a greater force to pull the corresponding first mounting plate 5112 to move. Since the cylinder bodies such as the detection cylinder 511 (whether it is an air cylinder, a hydraulic cylinder or other cylinders that expand and contract depending on pressure) need to be in a negative pressure state when contracting their corresponding piston rods, the smaller the negative pressure, the greater the force to contract the piston rod. Therefore, in order to provide a greater contraction force for the piston rod of the detection cylinder 511, the pressure in the detection cylinder 511 on the side of surface D of the workpiece must be smaller than the pressure in the detection cylinder 511 on the side of surface E of the workpiece, and this can be used to determine whether the airtightness of the workpiece placement surface meets the requirements.

[0050] The judgment criteria for whether the airtightness of the placement surfaces on both sides of the workpiece meets the requirements are as follows:

[0051] In the conveying direction of the workpiece, if the values displayed on the pressure gauges on the left and right sides of the conveying direction are both less than or equal to the preset pressure value A, it means that the placement surfaces on both sides of the workpiece meet the airtightness requirements. If the value on the left pressure gauge is less than the value on the right pressure gauge, it means that the airtightness of the left placement surface of the workpiece is better, and the left placement surface of the workpiece can be placed on the electromagnetic suction block 401 in the electromagnetic frame 400, and vice versa;

[0052] In the conveying direction of the workpiece, if the values shown on the pressure gauges on both the left and right sides of the conveying direction are less than or equal to the preset pressure value A, and the values on the two pressure gauges are basically equal, it not only indicates that the placement surfaces on both sides of the workpiece meet the airtightness requirements, but also indicates that the smoothness of the placement surfaces on both sides of the workpiece is about the same. Either side of the placement surfaces on both sides of the workpiece can be selected and placed on the electromagnetic suction block 401 in the electromagnetic frame 400.

[0053] In the conveying direction of the workpiece, if the value shown on the pressure gauge on the left side of the conveying direction is less than or equal to the preset pressure value A, and the value shown on the pressure gauge on the right side is greater than the preset pressure value A, it indicates that the left placement surface of the workpiece meets the airtightness requirements, and vice versa.

[0054] In the conveying direction of the workpiece, if the values shown on the pressure gauges on both the left and right sides of the conveying direction are greater than the preset pressure value A, it indicates that the placement surfaces on both sides of the workpiece do not meet the airtightness requirements. At this time, if the clamping force applied to the workpiece by the second mounting plates 5121 on both sides of the workpiece is simultaneously cancelled, the workpiece can be removed from the mounting rack 500.

[0055] After judging the placement surface of the workpiece, the detection cylinder 511 and the clamping cylinder 512 are simultaneously driven to retract, so that the first mounting plate 5112 and the second mounting plate 5121 move synchronously and both move away from the workpiece. When the second mounting plate 5121 moves away from the workpiece, the workpiece is subjected to the suction force applied by the piston cylinder 5122 to the workpiece, and thus will drive the workpiece to move in the direction of the placement surface that meets the airtightness requirements.

[0056] If the placement surfaces on both sides of the workpiece meet the airtightness requirements, then the side towards which the workpiece moves indicates that the airtightness of that side is better; if the placement surfaces on both sides of the workpiece meet the airtightness requirements, and if the left and right movement distances of the workpiece are extremely small or even negligible, it indicates that the airtightness degrees of the placement surfaces on both sides of the workpiece are about the same; if one placement surface of the workpiece meets the airtightness requirements while the other does not, the workpiece will move towards the side that meets the airtightness requirements; if the placement surfaces on both sides of the workpiece do not meet the airtightness requirements, the workpiece is directly removed from the mounting rack 500, and then the airtightness of a new workpiece is detected.

[0057] When the airtightness detection of the placement surfaces on both sides of the workpiece is completed, the workpieces that do not meet the airtightness requirements are directly taken out of the mounting rack 500, and the workpieces that meet the airtightness requirements are conveyed to the sorting mechanism 200 driven by the conveying mechanism 300. The sorting mechanism 200 can sort the workpieces that meet the airtightness requirements, and can more intuitively show which side of the workpiece's placement surface meets the airtightness requirements, which is more convenient for placing the workpieces that meet the airtightness requirements on the electromagnetic suction block 401 in the electromagnetic frame 400.

[0058] In this embodiment, two detection mechanisms can simultaneously perform airtightness detection on two placement surfaces of the workpiece. After the detection, the workpiece can be directly transported by the transport mechanism 300 to the sorting mechanism 200. The staff can more clearly and intuitively know whether the placement surface of the workpiece meets the airtightness requirements, and can more conveniently place the side placement surface of the workpiece that meets the airtightness requirements on the electromagnetic suction block 401 in the electromagnetic frame 400. The better the airtightness of the workpiece placement surface, the smoother the placement surface, the fewer structures such as scratches and grooves on the placement surface that affect smoothness, and the larger the contact area with the electromagnetic suction block 401. The greater the reinforcement force / suction force of the electromagnetic suction block 401 on the workpiece with a smooth placement surface. When the electromagnetic suction block 401 sucks the workpiece tightly, the workpiece is more difficult to shake on the electromagnetic frame 400, and the machine tool will be more stable when processing the workpiece.

[0059] In some embodiments, the transport mechanism 300 includes transport rollers 310 for carrying the workpiece to be detected. The transport rollers 310 are rotated by a drive assembly provided on the mounting frame 500. The transport rollers 310 can be cylindrical roller shafts rotatably provided between two side plates of the mounting frame 500. Both ends of the transport rollers 310 can penetrate through the two side plates of the mounting frame 500, and both ends of the transport rollers 310 can be respectively flush with the plate surfaces of the corresponding side plates of the mounting frame 500. A plurality of transport rollers 310 can be provided, and the plurality of transport rollers 310 are evenly distributed along the length direction of the first mounting plate 5112. A plurality of roller grooves can be formed on the bottom plate of the mounting frame 500, and the plurality of roller grooves are evenly distributed along the length direction of the first mounting plate 5112. The plurality of transport rollers 310 are respectively provided in the plurality of roller grooves. The workpiece to be detected can be placed on the plurality of transport rollers 310, and can move within the lower mounting frame 500, and can be transported between the second mounting plates 5121 corresponding to the two detection mechanisms.

[0060] The transport rollers 310 are rotated by a drive assembly provided on the mounting frame 500. The drive assembly can include a transport wheel 321. One end of the roller shaft can be fixedly connected with a fixed shaft, and the transport wheel 321 is sleeved and fixed on the fixed shaft. The transport wheel 321, the fixed shaft and the transport rollers 310 are coaxially arranged. A drive motor 322 is provided on the mounting frame 500. The drive motor 322 can be installed on one side plate of the mounting frame 500 facing the transport wheel 321. A drive wheel is installed on the output shaft of the drive motor 322, and a drive belt 323 is provided on the drive wheel. The drive belt 323 can be simultaneously sleeved on the transport wheel 321 and the drive wheel. When the drive motor 322 operates, the drive motor 322 can drive the drive wheel to rotate, and then can drive the drive belt 323 to rotate. The drive belt 323 can drive the transport wheel 321 to rotate, and finally realize the driving of the transport rollers 310 by the drive motor 322. When the transport rollers 310 rotate, the workpiece can move within the mounting frame 500, and the workpiece can be transported to the detection mechanism or the sorting mechanism 200 under the drive of the transport rollers 310.

[0061] In this embodiment, the conveying wheel 321 and the driving wheel can be sprocket wheels, and the corresponding driving belt 323 can be a chain. The chain is sleeved on the driving wheel and the conveying wheel 321 and meshes with the driving wheel and the conveying wheel 321, so that when the output shaft of the driving motor 322 rotates, it can ensure that the conveying wheel 321 rotates synchronously with the driving wheel, ensuring that the workpiece can be conveyed by the conveying roller 310. The driving motor 322 can be selected as a stepping motor or a servo motor. When the staff uses the stepping motor and the servo motor, it is easier to control the rotation speed of the stepping motor and the driving motor 322, and thus it is easier to control the moving speed of the workpiece on the mounting rack 500, avoiding the situation that when the conveying roller 310 stops rotating due to the too fast moving speed of the workpiece, the workpiece slips on the conveying roller 310, and preventing the workpiece after slipping from hitting the mounting rack 500 and other objects, thereby damaging the workpiece.

[0062] In some embodiments, the sorting mechanism 200 includes a bearing plate 210 and a partition plate 220. The bearing plate 210 is arranged on the mounting rack 500 and can receive the workpieces conveyed by the conveying roller 310. The partition plate 220 is arranged on the bearing plate 210. The partition plate 220 divides the space enclosed by the bearing plate 210 and the mounting rack 500 into an intermediate area 203, a left flat area 201 and a right flat area 202. The left flat area 201 is used to carry workpieces with a flat left placement surface, the right flat area 202 is used to carry workpieces with a flat right placement surface, and the intermediate area 203 is used to carry workpieces with flat placement surfaces on both sides.

[0063] Specifically, the bearing plate 210 is arranged on the bottom plate of the mounting rack 500 and is located between the two side plates of the mounting rack 500. The bearing plate 210 is on the conveying path of the conveying roller 310. Under the drive of the drive assembly in the above embodiment, the conveying roller 310 can convey the detected workpieces to the bearing plate 210. There are two partition plates 220, and both of the two partition plates 220 are vertically fixed on the bearing plate 210. The two partition plates 220 can divide the space formed between the bearing plate 210 and the two side plates of the mounting rack 500 into a left flat area 201, a right flat area 202 and an intermediate area 203. The left flat area 201 is the area formed between the left side plate of the mounting rack 500 and the adjacent partition plate 220 in the conveying direction of the workpiece by the conveying roller 310. The right flat area 202 is the area formed between the right side plate of the mounting rack 500 and the adjacent partition plate 220 in the conveying direction of the workpiece by the conveying roller 310. The intermediate area 203 is the area formed between the two partition plates 220.

[0064] As can be seen from the foregoing embodiments, when the workpiece is detected by the detection mechanism, it may approach the two side plates of the mounting frame 500. In the direction of the conveying roller 310 for conveying the workpiece, the workpiece with the left placement surface meeting the airtightness requirement and approaching the left side plate of the mounting frame 500 will be conveyed to the left flat area 201, and the workpiece with the right placement surface meeting the airtightness requirement and approaching the right side plate of the mounting frame 500 will be conveyed to the right flat area 202. The workpiece with both the left and right placement surfaces meeting the requirements will be conveyed by the conveying roller 310 to the middle area 203 because the distance of moving left or right in the mounting frame 500 is too small, while the workpiece with neither the left nor the right placement surface meeting the airtightness requirement will be directly taken out of the mounting frame 500 by the staff.

[0065] During the implementation of this embodiment, the workpiece to be detected is placed on the conveying roller 310 from one end of the mounting frame 500 away from the bearing plate 210, and the two placement surfaces of the workpiece to be detected are respectively oriented towards the two sides of the mounting frame 500. Then, the driving motor 322 is started, and the driving motor 322 drives the conveying roller 310 to rotate through the driving belt 323 and the conveying wheel 321. The rotation of the conveying roller 310 can convey the workpiece to be detected between the detection mechanisms on both sides of the mounting frame 500. The driving motor 322 is turned off, and then the detection mechanism is controlled to start the airtightness detection of the placement surface of the workpiece.

[0066] As can be seen from the above embodiments, how to detect the placement surface of the workpiece and how to determine whether the placement surface of the workpiece meets the airtightness requirement will not be elaborated here.

[0067] After judging the placement surface of the workpiece, the detection cylinder 511 and the clamping cylinder 512 are simultaneously driven to retract, so that the first mounting plate 5112 and the second mounting plate 5121 move synchronously and both move away from the workpiece. When the second mounting plate 5121 moves away from the workpiece, the workpiece is subjected to the suction force exerted by the piston cylinder on the workpiece, and thus will drive the workpiece to move in the direction of the placement surface meeting the airtightness requirement.

[0068] If both the placement surfaces on both sides of the workpiece meet the airtightness requirement, the side towards which the workpiece moves indicates that the airtightness of that side is better; if both the placement surfaces on both sides of the workpiece meet the airtightness requirement, and the distance of the workpiece sliding left and right on the conveying roller 310 is extremely small or even negligible, it indicates that the airtightness degrees of the placement surfaces on both sides of the workpiece are about the same; if one placement surface of the workpiece meets the airtightness requirement while the other does not, the workpiece will move towards the side meeting the airtightness requirement; if neither of the placement surfaces on both sides of the workpiece meets the airtightness requirement, the workpiece is directly removed from the mounting frame 500, and then the airtightness detection of a new workpiece is carried out.

[0069] After the workpiece moves on the mounting rack 500, the driving motor 322 is started. The driving motor 322 drives the conveying roller 310 to rotate through the driving belt 323 and the conveying wheel 321. The conveying roller 310 drives the workpiece to move. The conveying roller 310 can convey the workpiece onto the bearing plate 210 of the sorting mechanism 200 and convey it to the corresponding left flat area 201, right flat area 202 or middle area 203. Among them, the workpiece with the left placement surface meeting the airtightness requirements is conveyed to the left flat area 201, the workpiece with the right placement surface meeting the requirements is conveyed to the right flat area 202, and for the workpiece with both placement surfaces meeting the airtightness requirements, it will be conveyed to the area on the side with better airtightness of the placement surface. If the airtightness of the two placement surfaces is about the same and the difference is very small, the workpiece will be conveyed to the middle area 203.

[0070] By classifying the workpieces, the staff can more easily and directly select the workpieces suitable for placement on the electromagnetic suction block 401. For the workpieces in the left flat area 201, the side of the placement surface that meets the airtightness requirements is placed on the electromagnetic suction block 401 facing the electromagnetic frame 400. For the workpieces in the right flat area 202, the side of the placement surface that meets the airtightness requirements is placed on the electromagnetic suction block 401 facing the electromagnetic frame 400. For the workpieces in the middle area 203, the placement surface of any side that meets the airtightness requirements is placed on the electromagnetic suction block 401 facing the electromagnetic frame 400. The electromagnetic suction block 401 can better fix the workpieces that meet the airtightness requirements, enabling the workpieces to be better processed.

[0071] In some embodiments, as Figure 3 shown, a grid frame 410 is provided inside the electromagnetic frame 400. The grids of the grid frame 410 are set as electromagnetic mounting holes 4101, and the electromagnetic suction blocks 401 are arranged in the electromagnetic mounting holes 4101.

[0072] The grid frame 410 may include an outer frame 411, cross bars 412 and longitudinal bars 413. The outer frame 411 may be a rectangular frame. A plurality of cross bars 412 and longitudinal bars 413 may be provided. The plurality of cross bars 412 are evenly distributed inside the outer frame 411 along the length direction of one side beam of the outer frame 411. The plurality of longitudinal bars 413 are evenly distributed inside the outer frame 411 in a direction perpendicular to the cross bars 412. The longitudinal bars 413 and the cross bars 412 are vertically crossed inside the outer frame 411 to form the grid frame 410. The number of grids of the grid frame 410 is multiple, and the multiple grids are evenly distributed on the grid frame 410, that is, the electromagnetic mounting holes 4101 are evenly distributed on the grid frame 410. The number of electromagnetic suction blocks 401 is equal to the number of electromagnetic mounting holes 4101, and the electromagnetic suction blocks 401 and the electromagnetic mounting holes 4101 are in one-to-one correspondence. The electromagnetic suction blocks 401 evenly distributed on the grid frame 410 can generate a more uniform suction force on the workpieces placed on the electromagnetic frame 400, enabling the workpieces to be more stably reinforced on the electromagnetic frame 400.

[0073] Further, as Figure 3 , Figures 5 to 7 shown, an airtight compensation groove is provided in the grid frame 410. The airtight compensation groove includes a grid groove 421 and a straight groove 422. The grid groove 421 is formed in the grid frame 410 and is adapted to the grid frame 410. The straight groove 422 is formed in the grid frame 410 at the center of four adjacent electromagnetic mounting holes 4101. The straight groove 422 communicates with the grid groove 421. An air hole 414 communicating with the grid groove 421 is formed in the outer side wall of the grid frame 410. The air hole 414 penetrates through the corresponding side wall of the electromagnetic frame 400. The air hole 414 is connected with an air pipe 415. The air pipe 415 can extend out of the air hole 414 on the side wall of the electromagnetic frame 400 and is connected with the air exchange hole of an external suction device.

[0074] Specifically, the grid groove 421 may include a transverse groove 4211 and a longitudinal groove 4212. The transverse groove 4211 and the longitudinal groove 4212 are vertically and crosswise arranged. The transverse groove 4211 and the longitudinal groove 4212 form a grid-shaped communicating groove body. The transverse groove 4211 in the grid groove 421 may be formed in the cross bar 412 of the grid frame 410, and the longitudinal groove 4212 may be formed in the longitudinal bar 413 of the grid frame 410. Among them, the longitudinal groove 4212 may penetrate through the bottom of the transverse groove 4211 and extend below the bottom of the transverse groove 4211. The straight groove 422 is formed in the grid frame 410 at the center of four adjacent electromagnetic mounting holes 4101, that is, the straight groove 422 is formed at the intersection of the cross bar 412 and the longitudinal bar 413 of the grid frame 410. The straight groove 422 communicates with the grid groove 421. Specifically, the straight groove 422 may communicate with the transverse groove 4211. The air hole 414 is formed in the side wall of the grid frame 410 and can communicate with the grid groove 421. Specifically, the air hole 414 may communicate with a partial groove body of the longitudinal groove 4212 penetrating through the transverse groove 4211. The air pipe 415 connected to the air hole 414 may be connected with the air exchange hole of an external suction device. The external suction device may be an existing device with air extraction and supply functions, such as a suction fan or an air extractor. The air exchange hole is the air extraction hole of devices such as a suction fan or an air extractor. The external suction device can draw the inside of the grid groove 421 into a negative pressure state through the air pipe 415.

[0075] When the workpiece is placed on the electromagnetic frame 400, the workpiece will cover some openings of the straight groove 422. The electromagnetic suction block 401 can position and fix the workpiece. When the external suction device is turned on to suck the air in the grid groove 421, the force received by the workpiece is not only the electromagnetic suction force exerted by the electromagnetic suction block 401 on the workpiece, but also because the grid groove 421 will be in a negative pressure state, the workpiece will also receive the suction force from the grid groove 421, which can further strengthen the fixing degree of the workpiece on the electromagnetic frame 400, further reduce the possibility of the workpiece moving on the electromagnetic frame 400, so that when the workpiece is being processed, it will not slide due to the touch of the tool head of the machine tool or the shaking of the machine tool, and can make the workpiece be processed better.

[0076] In some embodiments, as Figures 3 - 7 shown, a grid frame 430 is slidably disposed in the grid groove 421. The grid frame 430 is adapted to the grid groove 421. A straight rod 433 adapted to the straight groove 422 is fixed on the grid frame 430. The straight rod 433 is inserted into the straight groove 422. The grid frame 430 is slidably disposed in the grid groove 421 along the length direction of the straight groove 422.

[0077] The grid frame 430 may include a first rod 431 adapted to the transverse groove 4211 of the grid groove 421 and a second rod 432 adapted to the longitudinal groove 4212 of the grid groove 421. A plurality of first rods 431 and a plurality of second rods 432 are provided, and are respectively located in the corresponding transverse groove 4211 and longitudinal groove 4212. The first rod 431 can be in close contact with the side wall of the transverse groove 4211 in the corresponding transverse groove 4211, and the second rod 432 can be in close contact with the side wall of the longitudinal groove 4212 in the corresponding longitudinal groove 4212. The first rod 431 and the second rod 432 can slide up and down along the length direction of the straight groove 422 in the corresponding transverse groove 4211 and longitudinal groove 4212. On the outermost groove wall of the grid groove 421, that is, on the groove walls of the transverse groove 4211 and the longitudinal groove 4212 closest to the outer frame 411 of the grid frame 410 of the grid groove 421, chutes parallel to the length direction of the straight groove are provided. Sliders adapted to the chutes are fixed on the side walls of the first rod 431 and the second rod 432 located in the transverse groove 4211 and the longitudinal groove 4212 closest to the outer frame 411 of the grid frame 410 of the grid groove 421. The sliders are inserted into the chutes and the groove walls of the sliders are in close fit with the groove walls of the chutes, thereby realizing the sliding of the grid frame 430 in the grid groove 421.

[0078] A plurality of straight rods 433 are provided. The plurality of straight rods 433 are respectively fixed at a plurality of joints of the first rod 431 and the second rod 432. The plurality of straight rods 433 are parallel to each other and are perpendicular to both the first rod 431 and the second rod 432. The straight rod 433 is adapted to the straight groove 422 of the airtight compensation groove. The straight rod 433 is inserted into the straight groove 422. The side wall of the straight rod 433 can be in complete fit with the inner side wall of the straight groove 422. The straight rod 433 can slide along the length direction of the straight groove 422 in the straight groove 422 and can slide synchronously with the first rod 431 and the second rod 432. The grid frame 430 can seal the grid groove 421 and can slide along the length direction of the straight groove 422 in the grid groove 421. When the grid groove 421 is inflated through an external suction device, the grid frame 430 will drive the straight rod 433 to move away from the bottom of the grid groove 421 in the straight groove 422, and the straight rod 433 can lift up the workpiece placed on the electromagnetic frame 400.

[0079] One end of the straight rod 433 away from the grid frame 430 is provided with a universal ball 4331. The universal ball 4331 can protrude from the grid frame 410 and directly contact the placement surface of the workpiece, so as to realize the sliding of the workpiece on the grid frame 410.

[0080] Specifically, the universal ball 4331 has a certain load-bearing capacity and can support the workpiece. When the straight rod 433 moves in the direction away from the bottom of the grid groove 421, it can drive the universal ball 4331 to move in the direction away from the bottom of the grid groove 421, so as to support the workpiece. When the universal ball 4331 protrudes from the notch of the straight groove 422, placing the workpiece on the universal ball 4331 can realize the sliding of the workpiece on the electromagnetic frame 400, making it more convenient to move the workpiece to a suitable processing position.

[0081] After the workpiece is moved to a suitable processing position, control the external suction device to gradually stop inflating the grid groove 421 and gradually start to evacuate the grid groove 421. During this process, the workpiece will gradually approach the grid frame 410 and finally be placed on the grid frame 410. Since the external suction device evacuates the grid groove 421, the grid frame 430 will gradually approach the bottom of the grid groove 421 in the grid groove 421. At this time, the space in the straight groove 422 covered by the workpiece will become larger, and the air pressure will be in a negative pressure state. The straight groove 422 in the negative pressure state can further reinforce the workpiece, so that the workpiece can be fixed more stably on the electromagnetic frame 400 / grid frame 410, making it more convenient for the machine tool to process the workpiece.

[0082] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
