[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0056] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0057] When CNC machine tools are processing products, the positioning method of the products is generally to use a clamping plate to fix them. However, considering the surface processing of the product, positioning outside the product may block the surface to be processed, or block the cutting path of the CNC machine tool. From the perspective of tooling design, it is impossible to apply pressure to the product from the outside, so solving this problem becomes urgent.

[0058] In view of this, the present invention provides a positioning component and automatic processing equipment, which aims to achieve pressure-holding and positioning of the product by supporting the inner part of the product, so as to facilitate the processing of the outer area of ​​the product.

[0059] It should be noted that the positioning component mentioned in the present invention is used in a CNC machine tool, and is combined with the tool of the CNC machine tool to perform cutting processing on the product, but the positioning component is not limited to this. For positioning scenarios that require external processing of the product, the mechanism in this application can also be used to achieve internal support positioning. The positioning component can also be used as an auxiliary detection device.

[0060] Please refer to Figure 2 , Figure 5 and Figure 6 The positioning assembly 100 includes a mounting seat 1, a positioning structure 2 and a synchronous drive structure 3. The side of the mounting seat 1 in the first direction is the mounting side, and the mounting side has at least one mounting area, and the mounting area is used to carry the product; the positioning structure 2 includes a plurality of support members 21 arranged in the mounting area, and the plurality of support members 21 are arranged at intervals along the circumference of the mounting area, and the plurality of support members 21 can move in directions away from each other or close to each other, so that during the movement, the ends of the plurality of support members 21 facing away from each other can be pressed against the inner side wall of the product matching groove, or separated from the inner side wall of the product matching groove; the synchronous drive structure 3 is arranged on the mounting seat 1 to drive the plurality of support members 21 to move synchronously.

[0061] In the technical solution of the present invention, the product to be processed has at least a matching groove, so that the matching groove is set in a first direction, and the product is buckled on the installation area. Initially, the multiple support members 21 are close to each other, and when the product is buckled on the installation area, they are not in contact with the multiple support members 21. The multiple support members 21 are driven to move synchronously away from each other through the synchronous driving structure 3, so that they can press against the inner side wall of the product matching groove, clamp and fix it from the inside of the product, thereby limiting the position of the product on the mounting seat 1. The product can be tightened and loosened by adjusting the moving direction of the support member 21. The internal support solution solves the problem of being unable to hold the product from the outside due to the limitation of the processing surface of the product in the existing processing process, and facilitates the processing of the side wall and top surface of the product after positioning the product.

[0062] Taking the first direction as the up-down direction as an example, the product is a cover-shaped structure, and its matching groove is downwardly covered on the positioning structure 2. Initially, the multiple support members 21 are close to each other (see Figure 3 ), after the products are placed accordingly, the multiple support members 21 are driven to move away from each other to press against the inner wall of the matching groove of the product, thereby fixing the product (see Figure 4 ), the circumferential positioning makes the internal support of the product more evenly stressed.

[0063] It should be noted that the present invention does not limit the specific number of the plurality of support members 21. Considering the circumferential balance, the plurality of support members 21 are provided with at least three to form a stable triangular support. Considering that the matching groove of the product may be a circular cross section, a square cross section or even an anisotropic cross section, therefore, in this embodiment, please refer to Figure 2The plurality of support members 21 are arranged in four numbers, and every two are arranged opposite to each other on the same straight line, so as to correspond to the four sides of the product. Based on different product sizes, the sizes of every two opposite support members 21 remain consistent, and the sizes of the support members 21 on different straight lines can be the same or different.

[0064] The present invention does not limit the form in which the synchronous drive structure 3 realizes the synchronous drive. In some embodiments, the synchronous drive structure 3 can be realized by a structure such as a motor matching a synchronous belt, or can be driven by using multiple groups of associated cylinders. In this embodiment, please refer to Figures 6 to 8 The synchronous driving structure 3 includes a rotating disk 31 and a transmission structure 32. The rotating disk 31 is rotatably mounted on the mounting seat 1 along an axis extending in the first direction. The transmission structure 32 is connected to the rotating disk 31 and the plurality of supporting members 21 to convert the rotational driving force of the rotating disk 31 into the linear driving force of the plurality of supporting members 21. In this structure, the rotating disk 31 rotates to drive the plurality of supporting members 21 to do linear reciprocating.

[0065] Specifically, the transmission structure 32 can be realized by a structure in which a cam connecting rod cooperates. In some embodiments, the transmission structure 32 includes a plurality of driving grooves 321 and a plurality of driving members 322. The plurality of driving grooves 321 are arranged on the side of the turntable 31 facing the mounting seat 1. The plurality of driving grooves 321 extend along the circumference of the turntable 31, and in a rotation direction of the turntable 31, one end of the plurality of driving grooves 321 extends gradually away from the center direction of the turntable 31 to the other end; the plurality of driving members 322 are correspondingly penetrated through the plurality of driving grooves 321, and the plurality of driving members 322 are correspondingly connected to the plurality of supporting members 21. The present invention does not limit the specific shape of the driving grooves 321, which may be arc-shaped grooves or inclined extending grooves, as long as they can adapt to the rotation of the turntable 31 and the linear reciprocating stroke of the supporting member 21. During the rotation of the turntable 31, the driving member 322 can slide relatively in the driving groove 321, or move with the turntable 31, limited by the movement direction of the support member 21, so as to transmit the rotational drive of the turntable 31 to the support member 21 as a linear drive of the support member 21.

[0066] It should be noted that, in this embodiment, the driving groove 321 is arranged to penetrate in the first direction and is arranged in an arc shape.

[0067] It should be understood that the movable guide of the support member 21 can be naturally formed to stop rotation based on the structure of the support member 21, or a corresponding auxiliary guide structure can be provided. Specifically, the turntable 31 is located at the installation side; a guide seat 323 is provided between the turntable 31 and the mounting seat 1, and the guide seat 323 is fixed on the installation side. The guide seat 323 is provided with a plurality of guide grooves on the side of the turntable 31, and the plurality of guide grooves extend along the radial direction of the turntable 31 and are arranged along the circumference of the turntable 31; the plurality of support members 21 are slidably installed in the plurality of guide grooves at one end in the first direction, and the other end is fixedly connected to the plurality of driving members 322, so that the plurality of driving members 322 can drive the plurality of support members 21 to move along the plurality of guide grooves during the rotation of the turntable 31. It should be understood that the guide groove is a linear groove, and the extension direction of the plurality of guide grooves is determined according to the angle between two adjacent support members 21.

[0068] The support member 21 may be provided with a sliding block to be slidably mounted in the guide groove, or the entire support member 21 may be embedded in the guide groove for sliding fit, which is not limited in the present invention.

[0069] In other embodiments, corresponding guide grooves may also be provided on the mounting seat 1 without providing the guide seat 323 .

[0070] For further information, please refer to Figure 5 and Figure 7 , the turntable 31 is arranged on the installation side; the synchronous drive structure 3 also includes a drive assembly, the drive assembly includes a rotating shaft 33, a gear rack set and a drive unit 35, the rotating shaft 33 rotates along the axis extending in the first direction, one end of the rotating shaft 33 passes through the mounting seat 1 and is fixed to the middle of the rotating disk 31; the gear rack set includes a gear 341 and a rack 342 that mesh with each other, and the gear 341 is fixedly sleeved on the other end of the rotating shaft 33; the drive unit 35 is fixed to the side of the mounting seat 1 that is away from the installation side, so as to connect the rack 342. The drive unit 35 drives the rack 342 to reciprocate, thereby driving the gear 341 to rotate forward or reverse, and the rotating disk 31 moves synchronously with the gear 341 under the drive of the rotating shaft 33 to achieve rotational coordination. The meshing movement of the gear 341 and the rack 342 is used as the force transmission method, which has the advantages of high efficiency, stable transmission, high transmission accuracy and small error.

[0071] The driving part 35 is configured as a rodless cylinder, which occupies a small space and is adapted to the driving requirements. In order to facilitate the matching of the rack 342, an adapter plate can be added as a connection.

[0072] The meshing transmission of the gear 341 and the rack 342 is adopted, which has high precision and can ensure high transmission efficiency and small transmission error. The meshing transmission mode of the gear rack can reduce the transmission gap and make the transmission process stable. The gear rack transmission mode has a simple structure, small size and light weight. Compared with other transmission modes, it can save space and has a long service life.

[0073] When multiple installation areas are set on the installation side, multiple positioning structures 2 can be set at the same time for product positioning and installation. At this time, three gears 341 can be set corresponding to the three positioning structures 2, but only one driving part 35 and one rack 342 are set. One rack 342 can drive the three gears 341 to rotate, so that the corresponding three turntables 31 rotate at the same time, saving the number of parts and components, and also improving the consistency of product status.

[0074] It should be understood that when a plurality of positioning structures 2 are provided, a plurality of products can be processed together, thus avoiding the waste of tool changing time and improving the processing efficiency.

[0075] For further information, please refer to Figure 1 The driving assembly further includes a protective cover 36, which is used to cover the outside of the gear rack set, so as to prevent the chips in the processing process from entering the gear rack set, blocking the rotation of the gear 341 and affecting the power transmission.

[0076] It should be noted that the driving part 35 can be exposed outside the protective cover 36 or can also be arranged inside the protective cover 36. Different installation situations correspond to different sizes of parts, and the size of the mounting seat 1 needs to be matched.

[0077] Considering the initial positioning of the product in the installation area, please refer to Figure 6 The positioning structure 2 further includes a plurality of limit blocks 22, which are arranged on the periphery of the plurality of support members 21, and at least part of the plurality of limit blocks 22 can contact the inner side wall of the product matching groove when the product is placed. When the product is placed in the placement area, the plurality of limit blocks 22 are used to preliminarily position the product and limit the movement of the product on the plane.

[0078] It should be noted that the number of the plurality of limit blocks 22 and the plurality of support members 21 may be the same or different, and the positions may be directly opposite to the plurality of support members 21 or staggered. At the same time, considering the contact with the product, the side of each limit member facing away from the support member 21 is arranged in an arc shape to provide a transition when mating with the product to avoid contact with the tip, and the shape of the plurality of limit blocks 22 may also be adapted to the mating groove of the product. The product and the limit block 22 are clearance-matched.

[0079] Furthermore, the positioning structure 2 further includes a plurality of positioning pins 23 fixed to the mounting side and located at the periphery of the plurality of support members 21, and the plurality of positioning pins 23 are used to be inserted into the matching holes of the product. The plurality of positioning pins 23 are distributed along the circumferential direction, and are used to position the product together with the plurality of support members 21, thereby improving the positioning accuracy of the product.

[0080] Please follow Figure 2 In this embodiment, four limit blocks 22 are provided, corresponding to four support members 21 one by one, and three positioning pins 23 are provided, corresponding to two of the limit blocks 22, and located at the periphery of the limit blocks 22. First, the product is adjusted to the position of the four limit blocks 22 with reference to the position of the product, so that the three positioning pins 23 can be inserted into the matching holes of the product to achieve the fixation of the product, and then the multiple support members 21 are driven to open to further position the product, and the placement of the product is completed.

[0081] It should be noted that the positioning pin 23 can be always fixed, and its end is always exposed in the installation area, so that the positioning pin 23 can be used as a positioning basis when the product is placed. The positioning pin 23 can also be retractable and extend to cooperate with the product after the product is placed in the specified position. The present invention does not impose any restrictions on this.

[0082] Considering the arrangement of parts, please refer to Figure 1 and Figure 5 The mounting seat 1 includes two support blocks 11 and a bottom plate 12. The two support blocks 11 are arranged at intervals in a plane and are used to be installed on the bearing platform of a CNC machine tool. The bottom plate 12 is fixed to the ends of the two support blocks 11 to carry the product. At least part of the synchronous drive structure 3 is located between the two support blocks 11. Such an arrangement facilitates the lightweight of the mounting seat 1, while making the overall structure compact and reducing the space occupied by the positioning assembly 100.

[0083] Specifically, in this embodiment, the driving part 35 , the gear rack set, and the protective cover 36 are all located between two supporting blocks 11 , and the placement area is formed on the bottom plate 12 .

[0084] Furthermore, two weight-reducing holes are provided on each of the support blocks 11 , so that the support block 11 is in a Japanese shape as a whole, thereby achieving weight reduction of the support block 11 and ensuring the strength of the support block 11 .

[0085] The technical solution of the present invention is that the processing area of ​​the product is the top surface and the side wall, and an internal support solution is designed to simultaneously realize the positioning and holding functions of the product. The meshing movement of the gear 341 and the rack 342 is used as the force transmission method, which has the excellent characteristics of high efficiency, smooth transmission, high transmission accuracy, and small error. Multiple products can be processed together, eliminating the waste of tool change time. At this time, a rack 342 can drive multiple gears 341 to rotate, saving the number of driving components and also improving the consistency of product status. The use of highly mechanical automation reduces the investment in labor costs, and the use of machines to achieve automation can eliminate processing waste caused by manual operation errors.

[0086] Please refer to Figure 1 The present invention further proposes an automatic processing equipment 1000, which includes a positioning component 100. The specific structure of the positioning component 100 refers to the above embodiment. Since the automatic processing equipment 1000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0087] Specifically, the automatic processing equipment 1000 includes a CNC machine tool, which has a processing cavity. A supporting platform is arranged in the processing cavity, and the CNC machine tool performs cutting processing in the processing cavity; the positioning component 100 is located in the processing cavity, and the mounting seat 1 of the positioning component 100 is fixed on the supporting platform.

[0088] Furthermore, the automatic processing equipment 1000 also includes a loading tray 200 and a transfer assembly 300. The loading tray 200 is arranged in the processing chamber and is located on the side of the positioning assembly 100. The loading tray 200 is used to carry products. The transfer assembly 300 is arranged in the processing chamber. The transfer assembly 300 includes a movable pick-up portion 310, and the pick-up portion 310 is used to transfer products on the loading tray 200 or the positioning assembly 100. In this way, the three working modules of loading, processing and picking are integrated. With the cooperation of the positioning assembly 100, the transfer assembly 300 and the CNC machine tool, the fully automated processing of the product is realized. By driving the pick-up portion 310 to move to clamp the product to be processed on the loading tray 200, the automatic loading of the product is realized. Through the cooperation of the gear rack in the positioning assembly 100, the rotation transmission movement is realized, and the tightening and loosening of the product is realized through the conversion of the reciprocating movement of the support member 21. After the automatic processing of the CNC machine tool is completed, the picking unit 310 picks up the processed product and returns it to the loading tray 200. The entire product processing process does not require human participation and is completely completed by the program control of the AGV robot and the CNC machine tool, saving labor costs and improving the automation rate.

[0089] It should be noted that the material tray 200 is placed in the processing chamber, and can be placed directly on the carrier table or on the positioning shaft seat of the CNC machine tool in the processing chamber. When processing the product, the pickup part 310 can be moved to an evasive position without affecting the cutting function of the CNC machine tool.

[0090] The present invention does not limit the specific structural form of the pickup portion 310. In some embodiments, the pickup portion 310 can be configured as a suction cup. In this embodiment, the pickup portion 310 is configured as a clamping claw, which can be driven by a multi-axis driving structure to achieve multiple directions of movement, thereby adapting to the azimuth relationship between the positioning structure 2 and the material loading tray 200. For details, please refer to Figure 1 In this embodiment, the picking part 310 clamps the product through the cooperation of the pneumatic finger cylinder and the clamping claw. The pneumatic finger cylinder is controlled by the PLC program to realize the opening and closing functions, thereby driving the clamping claw to clamp and transport the unprocessed or processed products.

[0091] Furthermore, the pickup portion 310 should be driven to achieve a movable stroke in the first direction and a direction intersecting the first direction. For example, the pickup portion 310 may have a movable stroke in the up-down direction and the horizontal direction.

[0092] The first direction described in the present invention can be the up-down direction or the horizontal direction, which can be different according to the actual working conditions. The following takes the up-down direction as an example, and takes the example that the picking part 310 can move in the up-down direction and in the left-right and front-back directions to adapt to the position of the loading tray 200 and the mounting seat 1 to explain the operation principle of the device. The operation principle of the device is as follows:

[0093] Product loading: In the initial state, the pneumatic fingers are in the open state. Under the control of the PLC program, the main shaft is moved to the top of the loading tray 200, and the pneumatic fingers are controlled to drive the clamping jaws to retract, clamp the product, and move the product to the position above the positioning pin 23 in the installation area. The clamping jaws are released and the product is placed on the bottom plate 12. At this time, multiple limit blocks 22 limit the left and right and front and back movements of the product, and the positioning pin 23 is inserted into the matching hole of the product to complete the loading.

[0094] Product installation and positioning: In the initial state, multiple support members 21 are in a retracted state, and the unprocessed product is placed in the loading tray 200. The unprocessed product is clamped by the clamping claw and placed on the bottom plate 12. Three products are placed in sequence from left to right, and the discharge is completed. Start the rodless cylinder to slide, drive the rack 342 to slide to the left, and the rack 342 transmits power to the gear 341. The gear 341 converts the radial force into an axial force and transmits it to the turntable 31 on the same shaft 33, so that the turntable 31 rotates, and transmits the force to the multiple support members 21 through the multiple driving members 322. Due to the existence of the guide seat 323, the multiple support members 21 are limited to horizontal movement in the left and right directions or the front and back directions. The support member 21 finally stops in the state of tightening the product, and the clamping action of the product is completed.

[0095] After the product is clamped, processing can begin. Since the top surfaces of the three products are at the same height and the overall structure of the positioning assembly 100 is lower than the processing area of ​​the top surface of the product, one milling cutter can be used to mill the top surfaces of the three products at one time, thus saving processing time waste caused by tool change time.

[0096] After the processing is completed, the multiple supporting members 21 that hold the product tightly are retracted. The power source for the retraction process also comes from the rodless cylinder. The rodless cylinder slides to the right, driving the gear 341 to rotate counterclockwise. After the transmission of the rotating shaft 33, the turntable 31 also rotates counterclockwise, driving the multiple supporting members 21 to retreat. Then the clamping claw is controlled to put the processed product back into the loading tray 200.

[0097] The overall process adopts a fully automated processing method to reduce labor costs, increase machine utilization, improve processing stability, and increase overall profits.

[0098] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
