Description

Technical Field

[0001] This invention relates to the field of mechanical device technology, and in particular to a highly integrated product machining production line. Background Technology

[0002] The production process sometimes involves multiple processing steps. For example, one type of product is a long strip with two extension columns in the middle that are perpendicular to the length direction. The product needs to be precision ground on the outer circumference of the extension columns, as well as milled, tapped, and gear-shaping operations. Different processes require different processing tools.

[0003] Traditional processing methods separate the aforementioned steps, resulting in low efficiency. Furthermore, traditional machining fixtures are not ideally designed, unable to clamp multiple products simultaneously, further reducing processing efficiency. Additionally, products often exhibit varying degrees of deflection upon arrival, and traditional fixtures cannot press and shape them before clamping, affecting processing accuracy.

[0004] The purpose of this invention is to provide a highly integrated product machining production line that can achieve the above-mentioned objectives. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide a highly integrated product machining production line. By setting up a feeding platform, a material handling device, a crossbeam, a processing equipment, a conveying device, and a receiving mechanism, it can realize functions such as automatic loading and unloading of products, automatic tool changing, and completion of multiple processes on the same processing equipment. It has a high degree of integration, high degree of automation, and high processing efficiency.

[0006] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a highly integrated product machining production line, the production line including a machine base and a loading platform, a picking device, a crossbeam, several processing equipment, a conveying device and a receiving mechanism installed on the machine base, the crossbeam being erected on the machine base along the X direction, all the processing equipment being spaced apart along the X direction, the loading platform being located at the loading end of the production line, and the receiving mechanism being located at the unloading end of the production line;

[0007] The loading platform includes a flipping fixture and a secondary positioning fixture. The product is placed on the flipping fixture by the picking device, the product is flipped by the flipping fixture, and the flipped product is placed one by one on the secondary positioning fixture by the picking device.

[0008] The processing equipment includes a processing fixture, a pressing mechanism, a processing mechanism, and a tool magazine device. All products on the secondary positioning fixture are transported to the processing fixture by a transport device. The pressing mechanism presses and shapes the products from above. The processing fixture clamps and fixes the products. The processing mechanism performs machining on the products. The tool magazine device changes the tools of the processing mechanism.

[0009] The product is moved between the secondary positioning fixture, the processing fixture, and the receiving mechanism through a conveying device.

[0010] Furthermore, the pressing mechanism and the processing mechanism are respectively installed on both sides of the crossbeam; the processing fixture is a processing fixture that can move along the Y direction; the processing mechanism is a processing mechanism that can move up and down along the Z direction and move along the X direction.

[0011] The processing equipment is provided in multiple units;

[0012] The conveying device is a conveying device capable of moving along the X and Z directions;

[0013] The conveying device includes a loading and unloading base and two sets of picking mechanisms installed on the loading and unloading base, which are respectively defined as the first picking mechanism and the second picking mechanism. The first picking mechanism moves the product from the secondary positioning fixture to the processing fixture of the processing equipment, and the second picking mechanism moves the product on the processing fixture to the receiving mechanism.

[0014] Furthermore, the secondary positioning fixture is located downstream of the flipping fixture; the flipping fixture includes a first fixture base, a flipping lifting mechanism and a first positioning mechanism. The first fixture base has a first groove for placing the product. The flipping lifting mechanism lifts the product from below, causing the product to flip at a certain angle. The first positioning mechanism pushes the product to move along the X direction and limits its position using one side of the first groove as the X-direction positioning reference.

[0015] The secondary positioning fixture includes a second fixture base and a second positioning mechanism. The second fixture base has multiple spaced second grooves for placing products. The second positioning mechanism simultaneously pushes all products to move along the Y direction and limits their movement by using one side of the second groove as a Y-direction positioning reference.

[0016] Furthermore, the material handling device includes a material handling gripper that can move along the XYZ axes and a suction cup assembly that can move along the XYZ axes. The upper end of the suction cup assembly is also separately connected to a suction cup lifting drive cylinder that can drive the suction cup assembly to lift up and down.

[0017] Furthermore, both the first and second material handling mechanisms include a material handling seat and a material handling component mounted on the material handling seat. The material handling component includes a material handling drive cylinder and two sets of material handling grippers. The material handling drive cylinder drives the material handling grippers to grasp the product. At least one of the material handling mechanisms also includes an X-axis positioning mechanism, which includes an X-axis positioning drive cylinder and a positioning component. The X-axis positioning drive cylinder drives the positioning component to translate along the X-axis to limit the product in the X-axis.

[0018] Furthermore, the processing fixture includes a fixture base, a clamping mechanism, and a primary clamping drive unit and a secondary clamping drive unit capable of driving the clamping mechanism to translate along the Y direction. The fixture base has a second cavity, and the upper surface of the fixture base is provided with a plurality of product slots for placing products.

[0019] Furthermore, the clamping mechanism includes a push plate, spring seats, a lever, and a fixture cover plate. The push plate is installed in the second cavity and can move along the Y direction. The spring seats are fixed at intervals on the upper surface of the push plate. The lower end of the lever is located between adjacent spring seats, and the upper end is installed on the fixture cover plate. The lever and the fixture base are rotatably connected by a pin extending in the X direction. The power output ends of the primary clamping drive unit and the secondary clamping drive unit are directly or indirectly connected to the end of the push plate. The primary clamping drive unit and the secondary clamping drive unit drive the push plate to move, thereby moving the fixture cover plate along the Y direction to achieve clamping and releasing of the product in the Y direction.

[0020] An elastic element is installed inside the spring seat, and one end of the elastic element can press against the lower end of the lever;

[0021] The lower surface of the fixture cover plate has a mounting groove, the upper end of the lever is installed in the mounting groove, and the lower end of the lever is inserted into the gap between adjacent spring seats.

[0022] Furthermore, a first fixture pressure plate and a second fixture pressure plate are also installed on the upper surface of the fixture base, and the first fixture pressure plate and the second fixture pressure plate are respectively located at both ends of the product groove;

[0023] One end of the product slot extends to the inner side of the first fixture pressure plate, the inner side of the first fixture pressure plate is the Y-direction positioning reference surface, and the second fixture pressure plate is also provided with a plurality of clearance slots that mate with the product slot.

[0024] Furthermore, the pressing mechanism includes a pressing base, a pressing plate, a sliding seat, a pressing rocker arm, and a pressing drive cylinder. The pressing base is installed on the side of the crossbeam, the sliding seat is fixed to the pressing plate, and multiple pressing blocks are installed on the pressing plate. The pressing base has a sliding groove that matches the sliding seat. One end of the push rod of the pressing drive cylinder is rotatably connected to the tail of the pressing rocker arm via a first rotating shaft, and the middle position of the pressing rocker arm is also rotatably connected to the pressing base via a second rotating shaft. The upper end of the sliding seat has a slot, and the end of the pressing rocker arm can be inserted into the slot and drive the sliding seat to rise and fall along the slot.

[0025] Furthermore, the tool magazine device includes a tool magazine support frame and a tool magazine turntable mounted on the tool magazine support frame. The tool magazine turntable has multiple positioning holes for placing tools along its circumference, and a tool magazine rotation drive mechanism capable of driving the turntable to rotate is connected to the middle position of the tool magazine turntable.

[0026] The tool magazine turntable is covered by a fixed shell and a movable shell. The fixed shell has a notch and is fixed above the tool magazine support frame. One end of the movable shell has a shell translation drive cylinder that can drive it to move. The notch is covered or exposed by driving the movable shell to move through the shell translation drive cylinder.

[0027] The processing equipment is also equipped with a tool setting device.

[0028] The beneficial effects of this invention are:

[0029] 1. High integration, multiple processing steps completed in one clamping. This invention integrates functions such as loading, flipping, positioning, handling, processing, tool changing, and material collection into a single production line. After a single clamping, the product can sequentially complete multiple processing steps such as precision grinding, milling, tapping, and gear shaping without the need for transfer between different equipment, significantly improving processing efficiency.

[0030] 2. The flipping fixture works in conjunction with the secondary positioning fixture to achieve automatic multi-directional positioning of the product. The flipping fixture first flips the product 90° from a horizontal position to an upright position and completes the initial positioning in the X direction. Then, the secondary positioning fixture simultaneously pushes all products to complete the Y-direction positioning, resulting in high positioning accuracy. Furthermore, the secondary positioning fixture can hold multiple products (e.g., 8) at the same time, matching the subsequent processing cycle and improving loading efficiency.

[0031] 3. The combination of initial clamping and secondary clamping for pressing and shaping effectively solves the problem of product deflection. The processing fixture first pre-clamps the product (without locking it) through the initial clamping drive unit. Then, the pressing mechanism presses and flattens the product from above. Finally, the secondary clamping drive unit (with a multiplier cylinder for greater force) firmly clamps the product, effectively solving the problem of product deflection or dimensional errors when it arrives, and ensuring processing accuracy.

[0032] 4. The tool magazine device enables automatic tool changing without requiring manual tool replacement during machine downtime. The tool magazine turntable can rotate around the Z-axis, and together with the fixed and movable housings, it can protect the tools from dust contamination during machining and expose the tools during tool changes. It also has a tool adjustment structure to accommodate tools of different heights. After tool changing, the machining mechanism automatically sets the tool at the tool setter. The entire process does not stop the machine and is highly efficient.

[0033] 5. The material handling device integrates material handling and positioning functions, with dual material handling mechanisms coordinating loading and unloading. The first material handling mechanism of the device simultaneously possesses material handling and X-axis positioning functions, eliminating the need for a separate positioning mechanism and achieving a high degree of integration. The first and second material handling mechanisms work together—the first mechanism loads material while the second mechanism unloads simultaneously, reducing waiting time and improving production efficiency. Multiple processing devices can be arranged side-by-side along the X-axis, fully utilizing processing and material handling cycles to achieve multi-station parallel processing.

[0075] The following specific embodiments illustrate the detailed implementation of the present invention. Those skilled in the art can easily understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in the present invention.

[0076] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation shown in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this invention. The arrows in the accompanying drawings indicate the flow direction of products on the production line.

[0077] Example: A highly integrated product machining production line, such as Figures 1 to 29 As shown, the production line includes a machine base 55 and a loading platform 1, a material handling device 6, a crossbeam 54, several processing equipment 5, a conveying device 2, and a receiving mechanism 3 installed on the machine base. The crossbeam is mounted on the machine base along the X direction, and all the processing equipment is spaced apart along the X direction. The loading platform is located at the loading end of the production line, and the receiving mechanism is located at the unloading end of the production line.

[0078] The loading platform includes a flipping fixture 11 and a secondary positioning fixture 12. The product is placed on the flipping fixture by the picking device, the product is flipped by the flipping fixture, and the flipped product is placed one by one on the secondary positioning fixture by the picking device.

[0079] The processing equipment 5 includes a processing fixture 4, a pressing mechanism 51, a processing mechanism 52, and a tool magazine device 53. All products on the secondary positioning fixture are transported to the processing fixture by a transport device, the products are pressed and shaped from above by the pressing mechanism, the products are clamped and fixed by the processing fixture, the products are machined by the processing mechanism, and the tool magazine device is used to change the tools of the processing mechanism.

[0080] The product is moved between the secondary positioning fixture, the processing fixture, and the receiving mechanism through a conveying device.

[0081] In this embodiment, the pressing mechanism and the processing mechanism are respectively installed on both sides of the crossbeam 54; the processing fixture is a processing fixture that can move along the Y direction; the processing mechanism is a processing mechanism that can move up and down along the Z direction and move along the X direction.

[0082] The processing equipment is equipped with multiple units; it makes full use of the product processing cycle and the handling cycle of the conveying device to improve production efficiency.

[0083] The conveying device is a conveying device capable of moving along the X and Z directions;

[0084] The conveying device 2 includes a loading and unloading base 21 and two sets of picking mechanisms installed on the loading and unloading base, which are respectively defined as the first picking mechanism 22 and the second picking mechanism 23. The first picking mechanism moves the product from the secondary positioning fixture to the processing fixture of the processing equipment, and the second picking mechanism moves the product on the processing fixture to the receiving mechanism.

[0085] The working process of this production line is as follows:

[0086] The picking gripper 61 of the picking device 6 picks up the product 10 from the tray in the full area of ​​the loading platform and places it on the flipping fixture. The flipping fixture is used to achieve positioning in the X direction and to flip the product 90° so that the extension column of the product faces upward. Then the picking gripper 61 of the picking device 6 moves it to the secondary positioning fixture for positioning in the Y direction. The above process is repeated to place multiple products on the secondary positioning fixture in sequence. For example, in this embodiment, the secondary positioning fixture can hold 8 products. Afterwards, the first material handling mechanism of the conveying device moves to the secondary positioning fixture and simultaneously grabs the eight products, moving them to a certain processing equipment. The second material handling mechanism removes the processed products from the processing fixture. The first material handling mechanism places the eight products to be processed onto the processing fixture and performs X-axis and Y-axis positioning, pressing, and leveling on the products. Then, the processing fixture moves directly below the processing mechanism, and the processing mechanism sequentially performs the first process on multiple products (such as precision grinding of the outer circle of the extended column). Afterwards, the processing mechanism moves to the tool magazine device for tool changing and then performs the next process on the products (such as milling holes), until all processing processes are completed. Then, the processing fixture moves to the other side of the crossbeam, waiting for unloading. During the above process, the second material handling mechanism places the processed products into the receiving device for centralized unloading.

[0087] The specific structure of the feeding platform 1 is as follows:

[0088] like Figures 4 to 9 As shown, the secondary positioning fixture 12 is located downstream of the flipping fixture 11. The loading platform 1 also includes a loading panel 13, on which the flipping fixture 11 and the secondary positioning fixture 12 are fixedly installed. The loading panel 13 is provided with a full material area 131 and an empty material area 132. The full material area 131 is used to place a full material pallet, and the empty material area 132 is used to place an empty pallet.

[0089] The structure of the flipping fixture 11: as follows Figures 4 to 9 As shown, the flipping fixture 11 includes a first fixture base 111, a flipping and lifting mechanism 112, and a first positioning mechanism 113.

[0090] The first fixture base 111 has a first recess 1111 for placing the product 10. For example... Figure 1 As shown, product 10 is a long strip-shaped product, and product 10 has an extension post 101 perpendicular to the length direction at the middle position. The width of the middle position of the first groove 1111 is greater than the width at both ends to match the extension post 101 of product 10.

[0091] The tilting and lifting mechanism 112 includes a tilting block 1121 and a tilting and lifting drive cylinder 1122. The tilting block 1121 is mounted on the power output end of the tilting and lifting drive cylinder 1122. The tilting block 1121 is a wedge-shaped block that is narrower at the top and wider at the bottom. The working surface of the tilting block 1121 includes a downwardly inclined slope 11211 and a flat surface 11212 located below the slope 11211. The distance between the flat surface 11212 and the side of the first groove 1111 is adapted to the width of the product 10 to ensure that the tilting block 1121 can smoothly tilt the product 10 from a horizontal state to an upright state by 90°. A slot 11213 is provided in the middle of the tilting block 1121 to avoid the extension column 101.

[0092] The first positioning mechanism 113 is a first positioning drive cylinder. The first positioning drive cylinder drives its push rod to move, so that the head of the push rod pushes the product 10 to move along the X direction, and limits the product 10 with one side of the first groove 1111 as the X-direction positioning reference.

[0093] The structure of the secondary positioning fixture 12: as follows Figures 4 to 9 As shown, the secondary positioning fixture 12 includes a second fixture seat 121 and a second positioning mechanism 122.

[0094] The second fixture base 121 has multiple spaced second grooves 1211 for placing the product 10. In this embodiment, there are 8 second grooves 1211, which can be adjusted according to actual needs. A sensor 123 for detecting the presence or absence of the product 10 is installed on the second fixture base 121 corresponding to each second groove 1211.

[0095] The second positioning mechanism 122 includes a positioning plate 1221 and a second positioning drive cylinder 1222. The power output end of the second positioning drive cylinder 1222 is fixedly mounted on the positioning plate 1221. Multiple sets of positioning posts 1223 extending along the Z direction are mounted on the positioning plate 1221. The positioning plate 1221 and the multiple sets of positioning posts 1223 are driven to move along the Y direction by the second positioning drive cylinder 1222, and the product 10 is limited by using one side of the second groove 1211 as the Y-direction positioning reference.

[0096] The second fixture seat 121 has a first cavity 1212 in the middle, the positioning plate 1221 is located in the first cavity 1212, and the positioning post 1223 passes through the hole in the second fixture seat 121 and extends out.

[0097] Working principle and process of the feeding platform:

[0098] The working process of the feeding platform 1 is as follows:

[0099] Step 1: Loading. The full material tray is placed in the full material area 131 of the loading panel 13. The picking device 6 takes out the horizontal product 10 from the full material tray and moves it into the first groove 1111 of the flipping fixture 11.

[0100] Step Two: Flipping. The flipping and lifting drive cylinder 1122 drives the flipping block 1121 to lift upwards. Since the working surface of the flipping block 1121 includes a downwardly inclined surface 11211, this inclined surface 11211 contacts the product 10 during the lifting process, gradually changing the product 10 from a horizontal state to an upright state, achieving a 90° flip of the product 10 from a horizontal to an upright state. The slot 11213 opened on the flipping block 1121 avoids the extension column 101 of the product 10 during the flipping process, ensuring smooth flipping. The distance between the plane 11212 below the working surface of the flipping block 1121 and the side of the first groove 1111 is adapted to the width of the product 10, ensuring that the product 10 is stably upright after flipping.

[0101] Step 3: X-axis positioning (or left and right positioning). The first positioning drive cylinder of the first positioning mechanism 113 drives its push rod to move, pushing the product 10 to translate along the X-axis. The product 10 is limited by one side of the first groove 1111 as the X-axis positioning reference, thus completing the initial X-axis positioning of the product 10.

[0102] Step 4: Transfer. The first positioning mechanism 113 is released, and the material handling device 6 is in place to move the initially positioned product 10 into the second groove 1211 of the secondary positioning fixture 12.

[0103] Step 5: Cyclic feeding. Repeat steps one through four above until sensor 123 detects that all the second grooves 1211 of the second fixture seat 121 contain the product 10.

[0104] Step Six: Y-axis positioning (or front and rear positioning). The second positioning drive cylinder 1222 drives the positioning plate 1221 and multiple sets of positioning columns 1223 to move along the Y-axis. The positioning columns 1223 push all products 10 to move simultaneously along the Y-axis. Using one side of the second groove 1211 as the Y-axis positioning reference, all products 10 are simultaneously limited, thus completing the Y-axis positioning.

[0105] Through the above process, the flipping fixture 11 realizes the transformation of product 10 from a horizontal to an upright state and the positioning of product 10 in one direction (X direction). Then, in conjunction with the secondary positioning fixture 12, it achieves positioning of product 10 in the other direction (Y direction). The ingenious structural design results in high positioning accuracy and improved loading efficiency. The secondary positioning fixture 12 is provided with multiple second grooves 1211, mainly to adapt to the processing rhythm of subsequent processes. In this embodiment, eight grooves are provided, which can be adjusted according to actual needs.

[0106] like Figure 10 and Figure 11 As shown, the material handling device 6 includes a material handling gripper 61 capable of moving along the XYZ axes and a suction cup assembly 62 capable of moving along the XYZ axes. The upper end of the suction cup assembly is also separately connected to a suction cup lifting drive cylinder 63 capable of driving the suction cup assembly up and down. This suction cup lifting drive cylinder is added to avoid interference when handling the tray. The material handling gripper picks up products from the tray and places them onto the flipping fixture; the suction cup assembly picks up empty trays and places them into the empty material area of ​​the loading platform.

[0107] The structure of the conveying device 2 is as follows:

[0108] Each material handling mechanism includes a material handling seat 221 and a material handling component mounted on the material handling seat 221. The material handling component includes a material handling drive cylinder 222 and two sets of material handling grippers 223. The material handling drive cylinder 222 drives the material handling grippers 223 to pick up the product 10.

[0109] The structure of the material handling jaw 223 is as follows: Figures 12 to 16 As shown, the material-grabbing gripper 223 includes two material-grabbing side plates 2231, which are mounted on the power output end of the material-grabbing drive cylinder 222. Each material-grabbing side plate 2231 is equipped with several material-grabbing blocks 2232. The material-grabbing drive cylinder 222 drives two opposing material-grabbing blocks 2232 to open outwards to support the product 10. The product 10 is a long strip-shaped product, and has an extension post 101 perpendicular to its length direction at its middle position. The outer surface of the material-grabbing block 2232 has an arc-shaped groove 22321 that matches the extension post 101, making the product 10 more securely fixed and preventing it from loosening or falling off. Multiple products (e.g., eight) can be fixed and clamped simultaneously using a single material-grabbing drive cylinder 222, resulting in high efficiency.

[0110] The structure of the X-axis positioning mechanism 224: as follows Figures 12 to 16 As shown, the first material handling mechanism 22 further includes an X-axis positioning mechanism 224. The X-axis positioning mechanism 224 includes an X-axis positioning drive cylinder 2241 and a positioning assembly. The positioning assembly includes a positioning push plate 2242 and several positioning push blocks 2243. The positioning push plate 2242 is mounted on the power output end of the X-axis positioning drive cylinder 2241, and all the positioning push blocks 2243 are mounted on the positioning push plate 2242. By driving the positioning push plate 2242 and the multiple positioning push blocks 2243 mounted thereon to translate along the X-axis by the X-axis positioning drive cylinder 2241, the product 10 is limited in the X-axis direction. Integrating the positioning function into the material handling mechanism eliminates the need for a separate X-axis positioning mechanism, reducing space and achieving a high degree of integration.

[0111] In this embodiment, as Figures 12 to 16As shown, an X-axis material handling and translation drive mechanism 24 is also installed on the loading / unloading base 21. A first material handling mechanism 22 or a second material handling mechanism 23 is mounted on the power output end of the X-axis material handling and translation drive mechanism 24. In this embodiment, the X-axis material handling and translation drive mechanism 24 is a drive cylinder, and one end of the push rod of the drive cylinder is fixed to the first material handling mechanism 22 or the second material handling mechanism 23. To ensure smooth movement, a linear slider rail structure can also be installed between the first material handling mechanism 22 or the second material handling mechanism 23 and the loading / unloading base 21.

[0112] The loading / unloading base 21 is also equipped with a material picking and lifting drive cylinder 25, the power output end of which is installed on the material picking base 221 of the first material picking mechanism 22. The material picking gripper 223 of the first material picking mechanism 22 has a lifting function to take into account the spatial position and avoid interference with other structures on the processing station.

[0113] In this embodiment, the loading / unloading base 21 is a loading / unloading base capable of moving along the X and Z directions. The mechanisms driving the loading / unloading base 21 to move along the X and Z directions are respectively the X-axis loading / unloading drive module 26 and the Z-axis loading / unloading drive module 27. The X-axis loading / unloading drive module 26 and the Z-axis loading / unloading drive module 27 can be a transmission mechanism of a servo motor and a nut screw, or they can be linear modules. This is prior art and will not be described in detail. As long as it can realize the movement of the loading / unloading base 21, it is acceptable.

[0114] The working process and working principle of the conveying device are as follows:

[0115] The X-axis upward loading and unloading drive module 26 and the Z-axis upward loading and unloading drive module 27 drive the loading and unloading seat 21 to move to the picking position. The picking lifting drive cylinder 25 of the first picking mechanism 22 drives the picking gripper 223 to descend. The picking drive cylinder 222 drives the two sets of picking grippers 223 to move and clamp multiple products 10 at the same time. The picking block 2232 opens outward to support the product 10. The arc groove 22321 cooperates with the extension column 101 to fix the product 10 firmly.

[0116] Subsequently, the X-axis loading / unloading drive module 26 and the Z-axis loading / unloading drive module 27 drive the loading / unloading seat 21 to the processing station. Then, the picking gripper 223 of the second picking mechanism 23 clamps and removes the processed product 10 from the processing station. The first picking mechanism 22 places the gripped product 10 to be processed onto the processing fixture at the processing station. Then, the X-axis positioning drive cylinder 2241 of the X-axis positioning mechanism 224 drives the positioning push plate 2242 and the multiple positioning push blocks 2243 mounted on it to push simultaneously along the X-axis, so that all products 10 cooperate with the hard positioning reference surface on the processing fixture for limiting, realizing the positioning of the product 10 in the X direction. After positioning is completed, the processing process is carried out. The X-axis loading / unloading drive module 26 and the Z-axis loading / unloading drive module 27 drive the loading / unloading seat 21 to the receiving mechanism 3. The X-axis material picking and translation drive mechanism 24 drives the second material picking mechanism to translate along the X-axis so that its picking claw is located directly above the receiving mechanism. The second material picking mechanism 23 places the processed product 10 onto the corresponding receiving channel.

[0117] Through the above process, this handling device realizes automatic loading and unloading when processing products at multiple workstations and on multiple machines. The first picking mechanism 22 has both picking and X-axis positioning functions, with a high degree of integration. The second picking mechanism 23 is responsible for picking up the processed products. The two picking mechanisms work together, which is highly efficient.

[0118] The structure of machining fixture 4 is as follows:

[0119] like Figures 17 to 23 As shown, the machining fixture includes a fixture base 41, a clamping mechanism, and a primary clamping drive unit 42 and a secondary clamping drive unit 43 capable of driving the clamping mechanism to translate along the Y direction.

[0120] The fixture base 41 has a second cavity 411, and the upper surface of the fixture base 41 is provided with a plurality of product slots 412 for placing the product 10 and extending along the X direction. In this embodiment, the product 10 is a long strip product, and the middle position of the product 10 has two extension columns perpendicular to the length direction. The product 10 needs to be precision ground on the outer circumference of the extension columns and processed by milling, tapping, and gear shaping.

[0121] like Figures 17 to 23 As shown, the upper end of the fixture base 41 is provided with a plurality of protrusions 413. A step for placing the product 10 is machined on one side of the protrusion 413, which is the product groove 412. The fixture cover plate 444 is installed between adjacent protrusions 413, and the product 10 is clamped by the cooperation between the adjacent fixture cover plates 444 and the protrusions 413.

[0122] The clamping mechanism includes a push plate 441, a spring seat 442, a lever 443, and a fixture cover plate 444. The push plate 441 is installed in the second cavity 411 and is movable in the Y direction. The spring seats 442 are fixedly spaced on the upper surface of the push plate 441. The lower end of the lever 443 is located between adjacent spring seats 442, and the upper end is installed on the fixture cover plate 444. The lever 443 is rotatably connected to the fixture base 41 via a pin 445 extending in the X direction.

[0123] An elastic element 446 is installed inside the spring seat 442, and one end of the elastic element 446 can press against the lower end of the lever 443. In this embodiment, the elastic element 446 is a spring, but it is not limited to this, and may also be other elastic elements such as an elastic sleeve.

[0124] In this embodiment, preferably, as follows: Figures 21 to 23 As shown, the left side of the spring seat is an inclined surface. When the product is released, this inclined surface cooperates with the elastic element to reset the lever. Finally, the right side of the lower end of the lever fits into the inclined surface of the left side of the spring seat.

[0125] The lower surface of the fixture cover plate 444 has a mounting groove 4441. The upper end of the lever 443 is installed in the mounting groove 4441, and the lower end of the lever 443 is inserted into the gap between adjacent spring seats 442. Thus, when the push plate 441 moves along the Y direction, the spring seat 442 presses against the elastic element 446, and the elastic element 446 pushes against the lower end of the lever 443, causing the lever 443 to rotate around the pin 445. The upper end of the lever 443 drives the fixture cover plate 444 to move in the opposite direction along the Y direction, thereby clamping or releasing the product 10.

[0126] The power output ends of the primary clamping drive unit 42 and the secondary clamping drive unit 43 are directly or indirectly connected to the end of the push plate 441. The push plate 441 is driven to move by the primary clamping drive unit 42 and the secondary clamping drive unit 43, which in turn drives the fixture cover plate 444 to move along the Y direction, thereby achieving Y-direction clamping and loosening of the product 10.

[0127] The upper surface of the fixture base 41 is also equipped with a first fixture pressure plate 447 and a second fixture pressure plate 448, which are located at both ends of the product slot 412. One end of the product slot 412 extends to the inner side of the first fixture pressure plate 447, which serves as the Y-axis positioning reference surface. The second fixture pressure plate 448 is also provided with several clearance grooves 4481 that mate with the product slot 412. Therefore, after other mechanisms place the product 10 into the product slot 412, the pushing components of other mechanisms push the product 10 inward. The product 10 will be positioned with the inner side of the first fixture pressure plate 447 as the Y-axis positioning reference surface, and then the secondary clamping drive unit 43 will clamp the product 10, thus achieving clamping and positioning in the X-axis.

[0128] In this embodiment, the initial clamping drive unit 42 is an initial clamping drive cylinder, and the end of the push rod of the initial clamping drive cylinder is fixed to one end of the push plate 441. The secondary clamping drive unit 43 is a secondary clamping drive cylinder, and the end of the push rod of the secondary clamping drive cylinder is not fixedly connected to the other side of the push plate 441, that is, the two only contact each other to transmit thrust and are not fixed as one. When the push rod of the secondary clamping drive cylinder extends, it drives the push plate 441 to move along the Y direction. When the push rod of the secondary clamping drive cylinder retracts, it pushes the push plate 441 back to its original position under the action of the elastic element 446.

[0129] Preferably, the secondary clamping drive cylinder is a force multiplier cylinder, and the force of the secondary clamping drive cylinder is greater than that of the primary clamping drive cylinder, so as to ensure that the final clamping force on the product 10 is large enough.

[0130] The working process of machining fixtures:

[0131] like Figure 23 As shown, when the processing fixture 4 is in the released state, the push rod of the initial clamping drive cylinder is in the extended state, and the push rod of the secondary clamping drive cylinder is in the retracted state. Then, the picking jaws of the first picking mechanism place multiple products 10 into the product slot 412 in sequence, and then the X-axis positioning mechanism on the first picking mechanism pushes the products 10 toward the side closer to the first fixture pressure plate 447, so that the products 10 are positioned with the inner side of the first fixture pressure plate 447 as the Y-axis positioning reference plane.

[0132] Afterwards, the push rod of the initial clamping drive cylinder retracts to perform initial positioning and pre-clamping of product 10 (specifically, it produces a certain clamping and positioning effect, but does not clamp product 10 completely). Specifically, when the push rod of the initial clamping drive cylinder retracts, it will drive the push plate 441 to move to the right, the spring will be compressed, and the lever 443 will rotate around the pin 445 as the rotation center. The upper end of the lever 443 will drive the fixture cover plate 444 to move to the left, performing initial positioning and pre-clamping of product 10.

[0133] Then, in conjunction with the pressing mechanism 51, the product 10 is pressed and shaped from above (because some products 10 have dimensional errors or slight curvature). After the other pressing mechanisms are lifted, the push rod of the secondary clamping drive cylinder (this push rod is not fixedly connected to the push plate 441) extends and continues to push the push plate 441 to the right, further driving the upper end of the lever 443 and the fixture cover plate 444 to the left. And because the force of the secondary clamping drive cylinder is relatively large, it will clamp and fix the product 10. Figure 21 and Figure 22 As shown.

[0134] After product 10 is processed, the push rod of the secondary clamping drive cylinder retracts, the push rod of the primary clamping drive cylinder extends, the spring force is released, and the lever 443, push plate 441, and fixture cover plate 444 return to their original positions, releasing product 10. Figure 23 As shown.

[0135] The structure of processing equipment 5 is as follows:

[0136] like Figure 17 , Figure 18 as well as Figures 25 to 27 As shown, the pressing mechanism 51 and the processing mechanism 52 are respectively installed on both sides of the crossbeam 54. The processing equipment can be used individually or in combination according to production needs. The processing fixture 4 is a processing fixture that can move along the Y direction, and the processing mechanism 52 is a processing mechanism that can be lifted and lowered along the Z direction and moved along the X direction.

[0137] The machining fixture 4 and tool magazine device 53 of the machining equipment 5 are mounted on the machine base 55. The machine base 55 is also equipped with an air blowing structure 56, which can aim at the product 10 on the machining fixture 4 and blow air to clean the product 10, preventing dust and impurities from affecting the processing quality. The air blowing structure 56 includes multiple air blowing heads, which can be connected to external gas. It is existing technology and will not be described in detail.

[0138] The structure enabling the machining fixture 4 to move along the Y direction is the Y-axis translation drive module 57. The structures enabling the machining mechanism 52 to move vertically along the Z direction and move along the X direction are the Z-axis translation drive module 58 and the X-axis translation drive module 59, respectively. The Y-axis translation drive module 57, Z-axis translation drive module 58, and X-axis translation drive module 59 can be a transmission structure of servo motors and lead screws, or they can be linear drive modules. The specific structure is not limited, as long as it can achieve stable movement of the components. This is existing technology, so it will not be described in detail.

[0139] like Figure 17 , Figure 18 as well as Figures 25 to 27 As shown, the pressing mechanism 51 includes a pressing base 511, a pressing plate 512, a sliding seat 513, a pressing rocker arm 514, and a pressing drive cylinder 515.

[0140] The pressing base 511 is mounted on the side of the crossbeam 54. The sliding seat 513 is fixed on the pressing plate 512, on which multiple pressing blocks 5121 are mounted. The pressing base 511 has a groove that matches the sliding seat 513. One end of the push rod of the pressing drive cylinder 515 is rotatably connected to the tail of the pressing rocker arm 514 via a first rotating shaft 516, and the middle position of the pressing rocker arm 514 is also rotatably connected to the pressing base 511 via a second rotating shaft 517. The upper end of the sliding seat 513 has a slot 5131, and the end of the pressing rocker arm 514 can be inserted into the slot 5131, driving the sliding seat 513 to rise and fall along the groove.

[0141] Preferably, the side of the slot 5131 closest to the pressing drive cylinder 515 is flared to avoid interference when the pressing rocker arm 514 swings; the end of the pressing rocker arm 514 is arc-shaped to ensure the smoothness of the sliding seat 513 rising and falling when the pressing rocker arm 514 swings.

[0142] The pressing mechanism is compact and low-cost. It adopts a transmission structure that combines a pressing drive cylinder with a pressing rocker arm and a sliding seat. The upper end of the sliding seat is slotted to fit with the end of the pressing rocker arm, ensuring smooth operation and preventing jamming. Compared with directly using a cylinder for up-and-down drive, it saves more space and is less expensive than a servo motor drive structure.

[0143] The working process of the pressing mechanism 51 is as follows: the push rod of the pressing drive cylinder 515 extends, causing the end of the pressing rocker arm 514 away from the pressing drive cylinder 515 to move downward, driving the sliding seat 513, the pressing plate 512, and the pressing block 5121 mounted on the pressing plate 512 to move downward, pressing the product 10 from above and flattening the product 10. In this structure, the upper end of the sliding seat 513 has a slot 5131, and the end of the pressing rocker arm 514 can be inserted into the slot 5131 and drive the sliding seat 513 to rise and fall along the slot. This makes the entire structure move more smoothly and avoids the head of the pressing rocker arm 514 from getting stuck. Compared with directly using a cylinder to drive the pressing up and down, this structure saves more space while achieving the required function; and it is less expensive than a servo motor driven structure.

[0144] like Figure 17 , Figure 18 as well as Figures 25 to 27 As shown, the tool magazine device 53 includes a tool magazine support frame 531 and a tool magazine turntable 532 mounted on the tool magazine support frame 531. The tool magazine turntable 532 has multiple positioning holes 5321 along its circumference for placing tools 20. A tool magazine rotation drive mechanism 533, capable of driving the turntable 532 to rotate, is connected to the center of the turntable 532. This tool magazine rotation drive mechanism 533 can be a transmission structure of a servo motor and a cam divider; this is existing technology and will not be described in detail. It only needs to be able to drive the tool magazine turntable 532 to rotate the required angle.

[0145] The tool magazine turntable 532 is covered by a fixed shell 534 and a movable shell 535. The fixed shell 534 has a notch 5341 and is fixed above the tool magazine support frame 531. One end of the movable shell 535 is connected to a shell translation drive cylinder 536, which drives the movable shell 535 to move, thus covering or exposing the notch 5341. The fixed shell 534 and the movable shell 535 are set at the tool magazine turntable 532 to protect the tool 20, because a lot of dust and impurities are generated during machining. The movable shell 535 is set so that it can protect the tool 20 during machining and expose the tool 20 during tool changing without affecting the tool changing process.

[0146] The processing equipment 5 is also equipped with a tool setting device 537.

[0147] The tool magazine turntable 532 is also equipped with multiple sets of tool adjustment structures 538. Each tool adjustment structure 538 includes a tool adjustment block 5381 and a tool adjustment nut 5382. The root of the tool adjustment block 5381 is mounted on the tool magazine turntable 532, and the tool adjustment nut 5382 is threadedly connected to the threaded hole on the tool adjustment block 5381. The upper end of the tool adjustment nut 5382 provides support for the tool 20 from below. This structure is designed to adjust the position of the tool adjustment nut 5382 on the tool adjustment block 5381 according to the height of different tools 20, so that the placement height of the tool 20 meets the requirements, facilitating tool changing by the subsequent machining mechanism 52.

[0148] The spindle of machining mechanism 52 is a spindle with a tool unloading structure. The tool unloading structure and its principle are existing technology and not part of the innovation of this invention, therefore they will not be described in detail. Traditional machining equipment does not have a tool magazine, but the spindle still has a tool unloading structure, where the old tool is manually removed and replaced with a new one. The innovation of this invention lies in adding a tool magazine device 53, not in the design of the tool unloading structure, and since the tool unloading structure and its principle are existing technology, they will not be described in detail.

[0149] The tool changing process of the tool magazine device 53 is as follows: The tool magazine device 53 can rotate around the Z-axis. When a tool change is needed, the machining mechanism 52 moves to the tool magazine device 53. The housing translation drive cylinder 536 drives the movable housing 535 to move and expose the notch 5341. The tool unloading structure inside the spindle is activated (the tool unloading structure is generally driven by hydraulic or pneumatic pressure), releasing the original tool and dropping it into the empty positioning hole 5321 of the tool magazine turntable 532. Then the tool magazine turntable 532 rotates to the required angle so that the tool required for the new process is located directly below the spindle. Then the tool unloading structure is activated again to clamp the tool required for the new process and moves to the tool setting device 537 for tool setting. After that, all mechanisms return to their original positions.

[0150] The complete working process of processing equipment 5:

[0151] Multiple products 10 are placed on and clamped onto the machining fixture 4. An air-blowing structure 56 cleans all products 10. Then, a Y-axis translation drive module 57 drives the machining fixture 4 to move directly below the pressing mechanism 51, which then presses and flattens the products 10. The Y-axis translation drive module 57 then drives the machining fixture 4 to move directly below the machining mechanism 52. Next, an X-axis translation drive module 59 and a Z-axis translation drive module 58 drive the machining mechanism 52 into position, sequentially performing the first type of machining on all products 10, such as fine grinding the outer cylindrical surface of an extended column. After this process is completed, the X-axis translation drive module 59 drives the machining mechanism 52 to the tool magazine device 53, where the tool 20 required for the next machining process is loaded. The mechanism then moves to the tool setter 537 for tool setting, and then moves directly above the machining fixture 4 to machine the products 10, such as milling holes. Repeat the above tool change-tool setting-machining process until all processes (such as fine grinding, milling, tapping, gear shaping, etc.) are completed. Then, the Y-axis translation drive module 57 drives the machining fixture 4 back to the initial position, waiting for material to be unloaded.

[0152] The structure of receiving mechanism 3: as follows Figures 28 to 29 As shown, the receiving mechanism 3 includes a grid-type base 31 and a pushing structure 32.

[0153] The grid-type base 31 is equipped with multiple Y-oriented upper support columns 311 and lower support columns 312. Adjacent lower support columns 312 and upper support columns 311 located on their left and right sides form a receiving channel. The lower support columns 312 support the product 10 from below, while the upper support columns 311 limit the product 10 from the side, preventing the product 10 from shifting or becoming disorderly in the horizontal plane. Multiple sets of receiving channels can be set up, corresponding to the number of processing stations. Products processed at different processing stations are placed in different receiving channels, facilitating traceability of processing stations during product inspection and enabling easy adjustment.

[0154] like Figures 28 to 29 As shown, the pushing structure 32 includes a pushing drive cylinder 321, a pushing seat 322, and multiple pushing blocks 323. The pushing blocks 323 are mounted on the pushing seat 322, which is mounted on the power output end of the pushing drive cylinder 321. The pushing blocks 323 pass through the gap between adjacent support columns and extend outwards. The pushing drive cylinder 321 drives the pushing seat 322 and the pushing blocks 323 to move along the Y-axis, pushing the products 10 to move along the Y-axis and arrange them together for easy removal later.

[0155] like Figures 28 to 29 As shown, the receiving mechanism 3 also includes a receiving support 33. The grid base 31 and the pushing structure 32 are both installed on the receiving support 33. The receiving support 33 facilitates the installation of the receiving mechanism 3 on the required machine or workbench.

[0156] The working process of the receiving mechanism 3: The second picking mechanism 23 places the processed product 10 onto the corresponding receiving channel. The lower support column 312 supports the product 10 from below, and the upper support column 311 limits the product 10 from the side to prevent it from shifting and becoming disorderly in the horizontal plane. The pushing drive cylinder 321 of the pushing structure 32 drives the pushing block 323 to move along the Y direction, pushing the product 10 to neatly gather together, making it easy to remove the product later. The receiving mechanism 3 is equipped with multiple sets of receiving channels, corresponding to the number of processing stations, which facilitates tracing the processing stations during product inspection and makes adjustments convenient.

[0157] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
