Description
Technical Field
[0001] This invention relates to the field of CNC machine tool technology, and particularly to auxiliary machining devices. Background Technology
[0002] In the industry, CNC machine tool machining solutions still heavily rely on manual material handling. Each product undergoes multiple steps during processing, including material handling, positioning, placement, and machining, resulting in low overall production efficiency. Furthermore, a large workforce is required for repetitive tasks, which not only increases production costs but also leads to inconsistent quality due to variations in human operation.
[0003] Furthermore, as consumer electronics products become increasingly complex, the shapes and designs of their internal cavities and peripheral components are becoming more diverse. Limited by the capabilities of existing processing equipment, traditional machining methods often require more steps to complete the fabrication of complex structures. During production, frequent product handling, cross-regional transfers, and jig changes are necessary. These steps not only significantly reduce processing efficiency but also easily lead to damage such as bumps, pressure marks, and scratches during handling, affecting the quality and yield of the final product. Summary of the Invention
[0004] The main objective of this invention is to provide an auxiliary processing device that enables the processing of multiple features of a product from one material handling cycle, eliminating the need for frequent process changes.

[0009] In one embodiment, the pressure member is made of a magnetically attractive metal material; The positioning component further includes a pressing structure, which is used to press and fix the pressing member onto the base.

[0010] In one embodiment, the base has a plurality of slots on its peripheral side. The positioning component further includes a lateral positioning structure, the lateral positioning structure comprising: A slider is movably mounted on the support in a horizontal direction and is located on one side of the base in the horizontal direction. One end of the slider can be inserted into one of the slots. A cylinder, the cylinder barrel of which is fixed to the support base, and the cylinder rod of which extends horizontally; and, A connecting rod, the two ends of which are respectively hinged to the other end of the cylinder and the slider.
[0011] In one embodiment, the lateral positioning structure further includes a housing that covers the outside of the slider and the base; and / or, The lateral positioning structure also includes a limiting seat, which is fixed on the support base. The limiting seat is provided with a limiting groove extending in the horizontal direction. The limiting groove is open on one side facing the base. The bottom wall of the limiting groove is provided with a through hole that passes through the support base on the side away from the base. The slider is slidably installed in the limiting groove. The upper end of the connecting rod passes through the through hole and is connected to the slider.
[0012] In one embodiment, the tray storage assembly further includes two limiting components, which correspond to opposite sides of the first fixed seat in the horizontal direction.

[0013] In one embodiment, the tray storage assembly further includes: A baffle is fixedly installed on the side end of the first fixed base and protrudes upward from the first fixed base; and, A protective cover, one side of which is open to form an open side, is movably mounted to the first fixed base in a horizontal direction and can cover the outside of the material tray, the open side of which is used to abut against the baffle.

Multiple products are placed in a tray, and after machining of the entire tray, they are removed together. The spindle drives the transport unit to move, facilitating product picking and placement, avoiding repetitive loading actions, and thus reducing interruptions and interventions in intermediate stages. The spindle drives the adjusting component to move up and down and rotate, allowing it to abut against the base and rotate synchronously to adjust the product placement angle, avoiding repeated clamping, saving time and reducing errors caused by multiple clamping operations. The entire process relies primarily on the spindle's degrees of freedom for machining, thus achieving good compatibility with four-axis CNC machine tools without major modifications to existing equipment, meeting the multi-directional machining requirements of complex products. It enables multi-angle machining of products after a single clamping, improving machining efficiency. Meanwhile, the rotatability of the spindle and base enables the product to be reset after the angle is adjusted, thus solving the problem that the original tray cannot be adapted after the product posture is changed. This design allows the same tray to be used for loading before processing as well as for temporary storage and transfer after processing, enhancing the standardization and universality of the tray, reducing the cost of using special tooling, and improving the utilization efficiency of production resources.

[0020] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0022] It should be noted that if the embodiments of the present invention involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0023] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0024] Currently, consumer electronics products are becoming increasingly complex in structure, with more and more diverse internal cavities and surrounding structures. Due to limitations in equipment capabilities, traditional machining methods require numerous processes. Some products even require more than a dozen processes to complete just one CNC machining operation. This process change is mainly because each product often has multiple surfaces to be machined. However, due to limitations in the type of CNC machine tool, four-axis CNC machine tools cannot provide the corresponding automatic angle adjustment. Therefore, various types of fixtures are required. After the machining of a single surface of the product is completed, the positioning fixtures for changing the angle of the product and the angle of the new machined part need to be changed. During this process, frequent product handling, turnover of the machining area, and changing of machining fixtures are required, which not only reduces machining efficiency but also easily causes bumps, dents, and scratches on the product. At the same time, each process requires tooling fixtures, which also increases the cost of fixtures.
[0025] In view of this, this application designs an auxiliary processing device that is applied in a CNC machine tool. By relying on the spindle, rotary axis and worktable of the CNC machine tool, it can realize the processing of features of multiple angles of the product in one go without frequent changes of process. Thus, it can realize the function of multi-process processing in one clamping and realize the processing of multiple processes in one process, which greatly improves the processing efficiency and can use a 4-axis machine to process 4.5-axis features.
[0026] It should be noted that the directional features mentioned in this invention are relative directions. The first horizontal direction and the second horizontal direction are two intersecting directions in the plane, which can correspond to the horizontal and vertical directions. Depending on the different placement of the device, the first horizontal direction and the second horizontal direction can also correspond to the front-back direction and the left-right direction.
[0027] Please refer to Figures 1 to 2 The auxiliary processing device 100 includes a tray storage assembly 1, a positioning assembly 2, a conveying assembly 3, and an adjusting assembly 4. The tray storage assembly 1 includes a first fixed base 11, which is used to install onto the worktable of the CNC machine tool. A tray 200 carrying multiple products 300 to be processed is placed on the first fixed base 11. The positioning assembly 2 includes a support base 21, a base 22, and a clamping member 23. The support base 21 is used to install onto the rotary axis of the CNC machine tool. The base 22 is rotatably mounted on the support base 21 along an axis extending vertically. The clamping member 23 is detachably installed onto the base 22 to cooperate with the base 22 to limit the products to be processed. The product 300 is positioned as follows: the conveying assembly 3 includes a conveying section 31, which is movable in the horizontal and vertical directions and can rotate along an axis extending in the vertical direction. The conveying section 31 is used to move the product 300 between the tray 200 and the base 22; the adjusting assembly 4 includes an adjusting member 40, which is movable in the vertical direction and can rotate along an axis extending in the vertical direction. The adjusting member 40 can abut against the base 22 during its vertical movement stroke, so as to drive the base 22 to move synchronously during its rotation; wherein, one of the conveying assembly 3 and the adjusting assembly 4 is used to connect to the spindle of the CNC machine tool.
[0028] In the technical solution of this invention, a series of operational steps, including material handling, clamping, processing, dynamic adjustment of the processing angle of product 300, and picking up processed product 300, can be completed within a CNC machine tool. Multiple products 300 are held in the tray 200. After processing the entire tray, they are removed together and moved by the spindle-driven transport unit 31. This facilitates the picking and placing of products 300, avoiding repetitive loading actions and reducing interruptions and interventions in intermediate stages. The spindle drives the adjusting component 40 to move up and down and rotate, which can abut against the base 22 and drive the base 22 to rotate synchronously, adjusting the placement angle of the product 300. This avoids repeated clamping, saving time and reducing errors caused by multiple clamping operations. The entire process relies primarily on the spindle's degrees of freedom for processing. Therefore, without major modifications to existing equipment, it achieves good compatibility with four-axis CNC machine tools, meeting the multi-directional processing requirements of complex products 300. It realizes the function of multi-angle processing of product 300 after a single clamping, improving processing efficiency. Meanwhile, the rotatability of the spindle and base 22 enables the product to be reset after the 300-degree angle adjustment, thus solving the problem that the original tray cannot be adapted after the product's 300-degree posture change. This design allows the same tray to be used for loading before processing as well as for temporary storage and transfer after processing, enhancing the standardization and universality of the tray, reducing the cost of using special tooling, and improving the utilization efficiency of production resources.
[0029] The specific processing steps are as follows: Multiple products 300 to be processed are placed in the same tray and stored inside the CNC machine tool via the tray storage component 1. During processing, the transport unit 31 cooperates with the spindle of the CNC machine tool to pick up the product 300 from the tray 200 and transfer it to the base 22. The clamping member 23 and the base 22 together clamp and fix the product 300, limiting its vertical direction and ensuring the stability of the product 300 clamping. Then, the transport unit 31 on the spindle is replaced with a cutting tool to process the product 300, completing the processing. Afterwards, the cutting tool on the spindle is switched to the adjustment component 4, which drives the adjustment component 40 to abut against the base 22. During the rotation of the spindle, the base 22 can be rotated synchronously, thereby adjusting the angle of the product 300. The adjustment component 4 on the spindle is switched to the cutting tool, and the product 300 after the angle adjustment is processed again. This process may involve multiple angle adjustments and multiple processing of the product 300 until the current process is completed. The angle of the product 300 is reset, and the spindle is switched to the transport unit 31 to put the product 300 back into the tray 200.
[0030] It should be understood that the base 22 should be able to position and fix the product 300. Therefore, a contoured groove can be provided on the base 22 to match the shape of the product 300. In this embodiment, at least two positioning posts are provided on the end face of the base 22. Each positioning post can be fitted with a hole on the product 300 to form a stable positioning effect.
[0031] The adjusting member 40 and the base 22 should be able to cooperate with each other and rotate synchronously. Their specific structural forms are not limited; in some embodiments, please refer to... Figures 2 to 4 The base 22 has a first groove 222 located near its edge. The adjusting assembly 4 also includes a connecting seat 41 and a positioning pin 42. The upper end of the connecting seat 41 is detachably connected to the spindle of the CNC machine tool. The positioning pin 42 is fixed to the lower end of the connecting seat 41, and its centerline is offset from the rotation axis of the connecting seat 41. The positioning pin 42 can be inserted into the first groove 222, thus engaging with the base 22. Since the positioning pin 42 is not concentric with the spindle, it can move in a circular trajectory around the spindle during spindle rotation, thereby applying force to the side wall of the first groove 222 and causing the base 22 to rotate relative to the support 21. It should be understood that the positioning pin 42 can engage with the first groove 222 during both clockwise and counterclockwise spindle rotation.
[0032] In this embodiment, to improve stability, two positioning pins 42 are provided, and two corresponding first grooves 222 are provided.
[0033] In other embodiments, a magnetic coupling positioning structure can be used. The adjusting component 40 includes an annular permanent magnet assembly, and a magnetically conductive metal ring is disposed on the base 22. The magnetic poles of the annular permanent magnet assembly are arranged in an alternating N-S pattern. The inner side of the ring is machined with concave and convex grooves that match the magnetic poles. When the connecting seat 41 moves downward, the permanent magnet assembly and the magnetically conductive ring automatically align through magnetic attraction, and the concave and convex grooves form a circumferential limit. This structure utilizes the magnetic field gradient to achieve non-contact pre-positioning, and combines it with the mechanical limit of the grooves to achieve precise locking. It is suitable for scenarios where the adjusting component 40 and the base 22 need to be frequently separated. However, when setting it up, the influence of the magnetic structure on the tool processing needs to be considered, and the magnetic field and the distance between it and the outer ring of the product 300 need to be reasonably set.
[0034] The main function of the clamping member 23 is to clamp the product 300 onto the base 22. The clamping member 23 can be clamped onto the end face of the product 300. When the product 300 is a watch case, the clamping member 23 can also be located in the inner cavity of the product 300.
[0035] When the holding member 23 and the base 22 together define the vertical position of the product 300, the holding member 23 can contact only the product 300, that is, the product 300 is clamped between the holding member 23 and the base 22, and a downward force is applied to the holding member 23 to achieve the function of the holding member 23; the holding member 23 can also contact both the product 300 and the base 22 simultaneously. Please refer to... Figures 5 to 6 Product 300 is a watch case with a hollowed-out portion at the bottom of its inner cavity. The base 22 is provided with a positioning groove 221. The bottom of product 300 contacts the end face of the base 22 and is limited in the horizontal direction by two positioning posts. The hollowed-out portion of product 300 can expose the positioning groove 221. The pressing member 23 is stepped. A part of the pressing member 23 abuts against the bottom wall of the inner cavity of product 300, and a part extends into the positioning groove 221 and is guided and cooperated with the inner side wall of the positioning groove 221. Force is applied to the part of the pressing member 23 that extends into the positioning groove 221, so that the pressing member 23 can maintain a good fit with product 300 and base 22, and can prevent product 300 from warping under force.
[0036] This invention does not limit the form in which force is applied to the holding member 23. In some embodiments, please refer to Figures 5 to 7 The holding member 23 has a mating hole 231 extending in the first horizontal direction in the middle; the positioning assembly 2 also includes a holding structure, which includes a pull rod 24 and a drive structure 25. The pull rod 24 can rotate along an axis extending in the vertical direction and can move in the vertical direction. The upper end of the pull rod 24 has a limiting part 240. During the rotation of the pull rod 24, the limiting part 240 has a first position and a second position. In the first position, the limiting part 240 extends in the first horizontal direction, and the shape of the mating hole 231 matches the shape of the limiting part 240 in the first position. This ensures that the limiting part 240 can smoothly move in the vertical direction through the product to be processed 300 and the mating hole 231. In the second position, the limiting part 240 extends in the second horizontal direction to press down against the surface of the holding member 23; the drive structure 25 is fixed on the support base 21 and connected to the lower end of the pull rod 24. Specifically, initially, the limiting part 240 is located on the lower side of the product 300. After the holding member 23 is installed in place, the limiting part 240 is kept in the first position, and the pull rod 24 is driven to move upward, so that the pull rod 24 passes through the product 300 and the mating hole 231. Then, the pull rod 24 is driven to rotate, and the limiting part 240 changes to the second position. At this time, the extension direction of the limiting part 240 intersects with the extension direction of the mating hole 231. Therefore, at least part of the downward projection of the limiting part 240 can fall on the holding member 23, rather than falling entirely in the mating hole 231. The pull rod 24 is controlled downward, and the limiting part 240 abuts against the holding member 23, thereby applying a downward force to the holding member 23.
[0037] It should be understood that when the adjusting member 40 drives the base 22 to rotate, the pull rod 24 maintains a pressing engagement with the holding member 23. Therefore, the pull rod 24 and the holding member 23 can rotate synchronously with the base 22, ensuring that the product 300 can still maintain good horizontal and vertical limits during the angle adjustment process.
[0038] The drive structure 25 can be directly implemented using a planar rotary cylinder 262, or it can be implemented by combining a motor and a transmission structure. This invention does not limit the implementation.
[0039] Please combine Figure 5 and Figure 8 In this embodiment, the drive structure 25 is a planar rotary cylinder 262. The cylinder barrel is connected to the support base 21 through a fixing plate. The cylinder rod is hinged to the tie rod 24, thereby allowing the tie rod 24 to tilt adaptively within a certain range. When the base 22 rotates, the tie rod 24 and the cylinder rod rotate relative to the cylinder barrel.
[0040] Considering that the pull rod 24 has a certain length, a guide support is provided between the base 22 and the drive structure 25. The guide support has a through hole through which the pull rod 24 can pass. The inner diameter of the through hole can limit the tilting range of the pull rod 24 during the lifting process.
[0041] To ensure smooth sliding of the base 22 and support 21, the base 22 and support 21 are rotatably connected by a double-row angular contact bearing 27. This bearing structure provides centering and better transmission performance. In this case, the guide support can directly serve as a bearing seat, with the bearing fixed on the outside and the tie rod 24 passing through on the inside.
[0042] In this embodiment, two sets of bearings are provided, which serves to reduce friction and provide centering.
[0043] The holding member 23 and the base 22 can be a single unit. For example, one end of the holding member 23 can be rotatably mounted on the base 22, and the other end can be rotated to cover the product 300 or to avoid the product 300. When the product 300 is picked up or put down, the holding member 23 can be rotated.
[0044] The clamping component 23 and the base 22 can also be separate structures. In this case, when placing or removing the product 300, the installation and removal of the clamping component 23 are involved. Please refer to [the relevant documentation]. Figure 2 and Figure 4The clamping member 23 is made of a magnetically attractive metal material; the positioning assembly 2 also includes a clamping structure for clamping and fixing the clamping member 23 onto the base 22; the adjustment assembly 4 includes a connecting seat 41 and a magnetic suction member 43. The upper end of the connecting seat 41 is detachably connected to the spindle of the CNC machine tool; the lower end of the connecting seat 41 is fitted with an adjustment member 40; the magnetic suction member 43 is located on the connecting seat 41 and spaced apart from the adjustment member 40, and is used to attract the clamping member 23. In this structure, the adjustment assembly 4 can both drive the base 22 to rotate and perform the function of picking up and placing the clamping member 23. After the product 300 to be processed is placed on the base 22, the adjusting component 4 first uses the magnetic attraction of the magnetic suction member 43 and the holding member 23 to move the holding member 23 to a position in contact with the product 300. Then, the holding structure controls the holding structure to hold and fix the holding member 23, so that the holding member 23 is relatively fixed to the product 300 and the base 22. The holding structure overcomes the magnetic force of the magnetic suction member 43, so that the holding member 23 can remain on the positioning component 2 when the adjusting component 4 is moved away. When it is necessary to adjust the processing angle of the product 300, even if the magnetic suction member 43 and the holding member 23 are re-attached and connected at the same time as the adjusting component 40 and the base 22, the holding member 23 will not move due to the influence of the magnetic suction member 43 under the constraint of the holding structure. When the product 300 is processed, the holding structure releases the constraint on the holding member 23. At this time, the connecting seat 41 moves to the corresponding position again, and the magnetic suction member 43 can magnetically attract and remove the holding member 23, so that the processed product 300 can be removed. This design allows adjustment component 4 to be compatible with both functions, resulting in a more compact overall structure.
[0045] In addition, the surface of the holding member 23 is provided with multiple through holes, and the connecting seat 41 is also provided with multiple limiting protrusions. These limiting protrusions can be inserted into the corresponding through holes for positioning when the magnetic suction member 43 and the holding member 23 are magnetically attracted and fixed. The limiting protrusions can be positioned at a distance from the magnetic suction member. Alternatively, the limiting protrusions can pass through the magnetic suction member 43.
[0046] It should be noted that in this embodiment, the adjusting member 40 can be set as a positioning pin 42, or it can be set as other structures, such as a buckle, a groove, etc. The pressing structure can be set as a structure in which the pull rod 24 and the driving structure 25 cooperate, and the pressing member 23 can also be a structure in which the cylinder 262 set in the support base 21 cooperates with the pressing rod. The present invention does not limit this.
[0047] It should be understood that when the holding structure includes the pull rod 24 and the adjusting member 40 is set as the positioning pin 42, the components will not interfere with each other based on their respective positional differences during each operation stage, which is conducive to the compact setting of the structure.
[0048] During the processing of product 300, the base 22 and the support 21 should be kept relatively fixed. Please refer to [reference needed]. Figure 2 , Figure 5 and Figure 8 The base 22 has multiple slots 223 on its peripheral side. The positioning assembly 2 also includes a lateral positioning structure 26, which includes a slider 261, a cylinder 262, and a connecting rod 263. The slider 261 is movably mounted on the support 21 in the horizontal direction and is located on the horizontal side of the base 22. One end of the slider 261 can be inserted into one of the slots 223. The cylinder barrel of the cylinder 262 is fixed to the support 21, and the cylinder rod of the cylinder 262 extends in the horizontal direction. The two ends of the connecting rod 263 are respectively hinged to the other ends of the cylinder 262 and the slider 261. The horizontal placement of the cylinder 262 is beneficial to the compact structure. During the horizontal extension and retraction of the cylinder rod, the connecting rod 263 swings, thereby driving the slider 261 to perform linear reciprocating motion, realizing the lateral locking and unlocking of the base 22 and the support 21.
[0049] The end of the slider 261 should be compatible with the shape of the slot 223. In this embodiment, the end of the slider 261 is set as a V-shaped structure, which can better define the position of the base 22.
[0050] It should be noted that the spacing between any two adjacent slots 223 can be the same or different, depending on the processing requirements of product 300.
[0051] It should be understood that a rotating shaft can be provided in the middle of the connecting rod 263, thereby limiting the torque transmission during the swinging process of the connecting rod 263, so that both ends of the connecting rod 263 always swing around, thereby driving the slider 261 to perform linear reciprocating motion more accurately. The rotating shaft can be installed in a suitable position on the support base 21.
[0052] Please refer to Figure 8 The lateral positioning structure 26 also includes a housing 264, which covers the outside of the slider 261 and the base 22 to prevent debris from entering the interior and affecting the rotational accuracy of the base 22 and the linear reciprocating motion of the slider 261.
[0053] Please refer to Figure 2The lateral positioning structure 26 also includes a limiting seat 265, which is fixed to the support base 21. The limiting seat 265 has a limiting groove extending horizontally, open on the side facing the base 22. A through hole is formed on the bottom wall of the limiting groove away from the base 22, penetrating the support base 21. The slider 261 is slidably installed in the limiting groove, and the upper end of the connecting rod 263 passes through the through hole and connects to the slider 261. The limiting seat 265 ensures the accuracy of the linear reciprocating motion of the slider 261, further constraining it and preventing deviation or wobbling during movement. The limiting seat 265 also prevents the slider 261 from deviating from its predetermined trajectory due to external factors, improving the reliability and stability of the entire lateral positioning structure 26. It should be noted that the limiting groove can be open on only one side or on both sides, facilitating the insertion and removal of the slider 261.
[0054] To ensure the stability of the tray 200 on the first fixed seat 11 during the loading and unloading of product 300, in some embodiments, please refer to... Figures 9 to 11 The material tray storage assembly 1 also includes two limiting components 12, which correspond to the two opposite sides of the first fixed base 11 in the horizontal direction. The two limiting components 12 have a moving stroke that moves closer to or further away from each other. Each limiting component 12 includes a first limiting block 121 and a second limiting block 122. The first limiting block 121 is in the horizontal direction and close to the other limiting component 12. The size of the first limiting block 121 is gradually reduced in the second horizontal direction. The first limiting block 121 is used to extend into the recess on the side of the material tray 200. The second limiting block 122 is fixed to the upper end of the first limiting block 121 and at least partially protrudes from the first limiting block 121 in the horizontal direction. The second limiting block 122 is used to press the upper surface of the material tray 200. The first limiting block 121 engages with the V-shaped recess on the material tray 200 to limit the X or Y direction, while the second limiting block 122 presses against the upper surface of the material tray 200 to limit the Z direction. Together, they clamp the material tray 200 onto the first fixing seat 11. This limiting structure also facilitates quick replacement of the entire material tray 200.
[0055] In the entire drive control process, each limiting component can be driven to move at least in the horizontal direction. In this embodiment, each limiting component 12 also includes a movable seat. Both movable seats are located on the lower side of the material tray 200 and are equipped with a dual-axis cylinder 262, which simultaneously drives the two movable seats to move towards or away from each other. During the movement of the two movable seats, the first limiting block 121 and the second limiting block 122 on them are driven to move synchronously. While the first limiting block 121 is engaged and positioned with the side of the material tray 200, the second limiting block 122 can correspond to the upper side of the material tray 200. It should be understood that there can be a certain gap between the second limiting block 122 and the material tray 200 to ensure smooth movement. This fit gap may cause the material tray 200 to have a certain amount of swaying, but the swaying amplitude is small and will not cause the product 300 to shake on the material tray 200.
[0056] Furthermore, the material tray storage assembly 1 also includes a baffle 13 and a protective cover 14. The baffle 13 is fixedly installed on the side of the first fixed base 11 and protrudes upward from the first fixed base 11. One side of the protective cover 14 is open to form an open side. The protective cover 14 is movably installed on the first fixed base 11 in a horizontal direction and can cover the outside of the material tray 200. The open side of the protective cover 14 is used to abut against the baffle 13. The baffle 13 serves a limiting function, and the protective cover 14 serves a protective function to prevent material debris and foreign objects from scratching the product 300. In this embodiment, the protective cover 14 is opened and closed by a rodless cylinder 262.
[0057] To allow the protective cover 14 to move horizontally on the first fixed base 11, a guide rail can be installed on the first fixed base 11, with the protective cover 14 slidingly engaging with the guide rail. The protective cover 14 can be made of transparent, high-strength plastic, which protects the product 300 from scratches by debris and allows operators to easily observe the condition of the product 300 within the tray 200. Furthermore, an anti-static coating can be applied to the inner surface of the protective cover 14 to prevent static electricity from attracting dust and other impurities, further ensuring the cleanliness of the product 300.
[0058] In addition, the auxiliary processing device 100 also includes an air blowing assembly 6 provided on the support base 21. The air blowing assembly 6 is located on the side of the base 22 and can blow air toward the base 22, thereby blowing air to clean up the chips during the cutting process.
[0059] The specific structural form of the handling component 3 is not limited. It can be a gripper structure, a suction nozzle mechanism, a magnetic suction structure, etc., and can be reasonably set according to the material and shape of the product 300.
[0060] In some embodiments, the conveying unit 31 is configured with two opposing first grippers 310. The two first grippers 310 can move relative to each other or away from each other to jointly grip the outer wall of the product 300. The two first grippers 310 are driven by a bidirectional cylinder 262. The conveying unit 31 is mounted as a whole by a floating structure. In order to improve the cooperation effect between the first grippers 310 and the product 300 and prevent the product 300 from detaching or moving during the conveying process, in some embodiments, please refer to... Figure 12 Both first grippers 310 have arc-shaped grooves 311 on their opposite sides to mate with the outer wall of the product 300. In some embodiments, please refer to... Figure 13 Each first gripper 310 includes two gripper arms spaced apart and arranged side by side. Each gripper arm has an elongated groove 312 inclined in the horizontal direction, which extends through the arrangement of the two gripper arms. The inclination directions of the two elongated grooves 312 on the two gripper arms of each first gripper 310 intersect. When the two first grippers 310 engage with the product 300, the protruding or flanged portion of the product 300 can be inserted into the elongated groove 312, thereby enabling the product 300 to be held and hung on the transport unit 31 while being gripped, thus providing better stability.
[0061] It should be noted that both the conveying assembly 3 and the adjusting assembly 4 are connected to universal tool holders for connecting to the equipment spindle.
[0062] The transport component 3 and the adjustment component 4, along with the cutting tools required for cutting, are placed in the tool magazine of the CNC machine tool. By setting the tool changing program of the CNC machine tool, the connection of different structures can be automatically changed.
[0063] As above, please combine Figure 1 In the first embodiment, the operation of the auxiliary processing device 100 is as follows: After the protective cover 14 is opened and the material tray 200 is placed in, the control limiting component 12 is activated, causing multiple first limiting blocks 121 to engage with corresponding V-shaped recesses on the material tray 200, and multiple second limiting blocks 122 to align with the upper surface of the material tray 200, thus achieving limiting of the material tray 200 in the X / Y directions and in the Z direction. The conveying component 3 performs a material picking action driven by the main shaft. Because it is installed on the main shaft of the equipment, it can grasp the product 300 at any angle. After picking up the product 300, it is placed on the base 22 and engages with the positioning pins on the base, while the protective cover 14 is closed. Then, the spindle drives the adjusting assembly 4 to place the holding member 23 onto the product 300. At this time, the planar rotary cylinder drives the pull rod 24 to rise and then rotates and pulls down to press the holding member 23. The spindle moves upward, the holding member 23 disengages from the magnetic suction member 43, the cylinder 262 in the lateral positioning structure 26 pushes out, drives the connecting rod 263 to swing, pushes out the slider 261, inserts it into the corresponding slot of the base 22, and uses leverage to firmly hold the product 300, ensuring the relative fixation of the base 22 and the support 21 during the processing. The spindle switches to a cutting tool to process the product 300. When it is necessary to switch to other angles after processing one angle, first retract the cylinder 262 in the lateral positioning structure 26 to separate the slider 261 from the slot, releasing the restriction on the base 22. Then the spindle switches to connect with the adjusting assembly 4, so that the positioning pin 42 engages with the first groove 222, driving the base 22 to rotate at an angle. As the spindle rotates, the holding member 23 and the pull rod 24 rotate synchronously. The double-row angular contact bearing 27 reduces friction and provides centering. After switching to another processing angle, the cylinder 262 in the lateral positioning structure 26 pushes out again, causing the slider 261 to insert into the corresponding groove and lock the base 22. The rotation of the base 22 and the locking and unlocking of the slider 261 are repeated to achieve the processing of more than 300 angle features of the product. During this process, the holding member 23 and the pull rod 24 will always remain in a pressed state to ensure the consistency of the processing of more than 300 angles of the product. When the product 300 is processed, the pull rod 24 is reset, and the spindle drives the adjustment component 4 to move above the product 300. The magnetic suction component 43 removes the holding member 23, which then drives the protective cover 14 to open again. The processed product 300 is placed and another product 300 is picked up, and the next cycle begins.
[0064] Please refer to Figure 14In the second embodiment, compared to the first embodiment, the auxiliary processing device 100 further includes a flipping component 5. The flipping component 5 is located to the side of the positioning component 2. In this embodiment, the flipping component 5 and the positioning component 2 are arranged side by side, both located on the same side of the tray storage component 1. This reasonable cooperation can effectively utilize the space inside the CNC machine tool. The flipping component 5 includes a second fixed seat 51, a rotating seat 52, and a clamping component 53. The second fixed seat 51 is used to be installed on the worktable of the CNC machine tool. The rotating seat 52 is rotatably installed on the side end of the second fixed seat 51 along an axis extending in the horizontal direction. The clamping component 53 is disposed on the rotating seat 52 and is used to clamp or release the product 300 to be processed transferred by the conveying unit 31. In this structure, based on the different processing requirements of product 300, not only can the horizontal angle adjustment of product 300 be satisfied, but also the flip angle adjustment of product 300. The transport unit 31 moves the product 300 to be processed or partially processed to the flipping assembly 5. After the clamping assembly 53 clamps and fixes product 300, the transport unit 31 releases product 300. Driven by the rotating seat 52, product 300 can rotate along the horizontally extending axis. After angle adjustment, the transport unit 31 picks up the adjusted product 300 at the adjusted angle and places it in the base 22 for the next stage of processing.
[0065] It should be noted that multiple contouring grooves can be set to correspond to different postures of product 300, or a single contouring groove can be set. However, the bottom of the contouring groove has multiple recessed structures. When product 300 is installed into the positioning groove 221 in different postures, different recesses and / or protrusions contact and cooperate with product 300, thereby accommodating positioning of product 300 at different angles. Multiple positioning posts can also be set to match the corresponding holes when the product is in different postures. Multiple positioning posts can have differences in height and diameter.
[0066] Similarly, multiple pressure-holding parts 23 with different shapes can be set to cooperate, or the pressure-holding parts 23 can be set to cooperate with different positions of the product 300 in different postures to realize the limiting function of the product 300 in different postures.
[0067] The specific structural form of the clamping component 53 is not limited. In this embodiment, the clamping component 53 includes two second grippers 531. The two second grippers 531 are provided with second grooves on their sides facing each other. Each second groove is adapted to the shape of the product 300.
[0068] In the second embodiment, the spindle drives the conveying assembly 3 to move the product 300 removed from the tray 200 or the base 22 onto the clamping assembly 53. The two second grippers 531 fix the product 300. The rotating seat 52 is driven by the rotary cylinder 262 to rotate the product 300. After rotating to a certain angle, it maintains this position. The spindle drives the conveying assembly 3 to remove the product 300 at this angle and place it on the base 22. Then, the spindle drives the adjusting assembly 4 to place the pressing member 23 onto the product 300. At this time, the planar rotary cylinder drives the pull rod 24 to rise and then rotates and pulls down to press and tighten. Holder 23 moves upward, spindle moves upward, holding member 23 disengages from magnetic suction member 43, cylinder 262 in lateral positioning structure 26 pushes out, driving connecting rod 263 to swing, pushing slider 261 out and inserting it into the corresponding slot of base 22, and relying on leverage to tightly hold product 300, ensuring the relative fixation of base 22 and support 21 during processing. Spindle switches to cutting tool to process product 300, repeating the rotation of base 22, locking and unlocking of slider 261, and flipping of flipping component 5, thereby realizing the processing of more than 300 angular features of product 300.
