[0002] CNC machining usually refers to computer digital controlled precision machining, such as CNC lathes, CNC milling machines, CNC boring and milling machines and other CNC machine tools. CNC machine tools are programmed and controlled by CNC machining languages, automatically controlling machining parameters such as tool feed speed, feed position and spindle speed, and have the advantages of high precision and repeatability.

[0003] With the development of metal processing, the popularity of various consumer electronics and their various metal parts and other products, the increasing demand for metal products, especially high-precision metal products, has led to the unprecedented promotion and application of CNC processing. However, in conventional CNC processing, such as CNC processing of rod-shaped workpieces, whether cylindrical, semi-cylindrical, or other special-shaped rods, although it is automated processing, the feeding and unloading are still done manually, which has the disadvantages of cumbersome overall process, low processing efficiency, great potential safety hazards for personnel, and great potential risks for product quality.

DETAILED DESCRIPTION

[0038] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0039] Those skilled in the art should understand that, in the disclosure of the specification, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0040] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0041] In the CNC processing of rod-shaped workpieces, one rod-shaped workpiece raw material can be processed into multiple finished products by CNC, which is generally determined based on the length of the raw material and the length of the finished product, such as the processing of screws or nut nuts, etc. It is suitable for various types of hard rod-shaped workpieces, such as cylindrical, semi-cylindrical and other special-shaped rod-shaped metal workpieces. Usually, the screws are clamped and locked manually, and the material is unloaded manually after the processing is completed, and then transferred to the next process for fine grinding or surface treatment. In the process of continuous batch processing and repetitive labor, frequent clamping and unloading not only affects the processing efficiency of the workpiece, but also easily causes manual fatigue, which poses a great hidden danger in terms of product quality and personnel safety.

[0042] Based on this, the present invention proposes a device for feeding and unloading based on CNC machining rapid automatic clamping, referring to Figures 1 to 8 , wherein the device for feeding and unloading based on CNC machining fast automatic clamping is suitable for CNC machining of a rod-shaped workpiece 90. The device comprises a supporting frame 10, a first clamping module 20, a pushing module 30, a second clamping module 40, a moving module 50 and a unloading clamping module 60, wherein the first clamping module 20, the pushing module 30, the second clamping module 40, the moving module 50 and the unloading clamping module 60 are all controllably connected to a CNC machining center, wherein the first clamping module 20, the pushing module 30 and the second clamping module 40 cooperate with each other on the supporting frame 10, mainly for realizing automatic feeding after one clamping, and the moving module 50 and the unloading clamping module 60 cooperate with each other on the supporting frame 10, mainly for realizing automatic unloading after CNC machining is completed. Generally, after a rod-shaped workpiece 90 is processed into 10 to 30 finished products, a certain length of tail will remain. The remaining tail can be processed again on a small machine or used as other materials. However, the device can increase the man-machine ratio of 1:3 under the traditional process of two hours of CNC processing to a man-machine ratio of 1:60, that is: after the rod-shaped workpiece 90 is manually placed into the device for the first time, the CNC processes the entire raw material in two hours, and one employee can look after 60 machines. This is the actual operating data for processing four rod-shaped workpieces 90 at the same time. Once the equipment has enough processing space and can process more rod-shaped workpieces 90 at the same time, the production efficiency will be further improved under the same man-machine ratio.

[0043] Specifically, the support base frame 10 includes a support base plate 11, a first support member 12, a second support member 13 and a fixed plate 14, wherein the first support member 12 and the second support member 13 are arranged on both sides of the support base plate 11 opposite to each other along the length direction of the support base plate 11, and the fixed plate 14 is fixedly connected to the top of the first support member 12 and the second support member 13. The first clamping module 20 is fixedly arranged on the top of the fixed plate 14 and close to the first support member 12. At the same time, the first clamping module 20 has a first clamping end 21 extending horizontally toward the direction of the second support member 13. The first clamping cavity 201 of the first clamping end 21 is surrounded by a first fixed block 211 and a first movable block 212 that can move relatively close to or away from the first fixed block 211, and is used to clamp the rod-shaped workpiece 90. The first clamping cavity 201 is at least provided with one group for clamping and fixing the rod-shaped workpiece 90. Each group of first clamping cavities 201 can be one first clamping cavity 201, or multiple first clamping cavities 201 can be provided, such as two or three, or even four, for clamping multiple workpieces 90 at the same time for CNC processing. The first fixed block 211 is fixedly arranged on the fixed plate 14 as a clamping reference, and also as a limit reference for the original placement position of the rod-shaped workpiece 90. The pushing module 30 is located below the fixed plate 14, between the first support member 12 and the second support member 13, and is fixedly disposed on the supporting base frame 10, wherein the pushing module 30 is non-collinear with the first clamping cavity 201 in the vertical direction to avoid interfering with the placement of the rod-shaped workpiece 90 and to avoid interfering with the automatic feeding of the rod-shaped workpiece 90 in the later stage.

[0044] Automatic feeding generally means that after processing a finished product, the rod-shaped workpiece 90 raw material placed on the device is automatically pushed upward a predetermined distance so that the raw material protrudes out of the first clamping end 21 by a predetermined height for CNC to process the next finished product, and so on, until the entire rod-shaped workpiece 90 on the device is processed and multiple finished products are processed.

[0045] The second clamping module 40 is located at the top of the pushing module 30, and is arranged below the fixed plate 14 in a manner that it can be driven by the pushing cylinder 33 on the pushing module 30 to move up and down. At the same time, the second clamping module 40 has a second clamping end 41 that cooperates with the first clamping module 20. The moving module 50 is fixedly arranged on the fixed plate 14, and has a moving part 51 that can move along the length direction. Accordingly, the fixed plate 14 is provided with a guide rail 144 for directional movement of the moving part 51. At the same time, the moving part 51 is higher than the first fixed block 211 by a predetermined distance in the vertical direction, and the unloading clamping module 60 is fixedly arranged on the moving part 51, and has a third clamping end 61 extending vertically downward, wherein the third clamping end 61 and the first clamping cavity 201 are located in the same length direction. In addition, the fixed plate 14 is also provided with a material containing channel cooperating with the first clamping cavity 201, and a material containing bin 141 is provided at one end close to the second support member 13, so that the device can unload the finished product processed by CNC at the first clamping module 20 into the material containing bin 141 through the unloading clamping module 60.

[0046] In detail, based on the cooperation of the first clamping cavity 201 on the first clamping end 21, the material containing channel and the second clamping end 41, a space for placing the rod-shaped workpiece 90 is formed in the vertical direction, wherein the material containing channel mainly plays a limiting and guiding role, and the first clamping end 21 and the second clamping end 41 mainly play a clamping role. The specific working process is: first, manually place the rod-shaped workpiece 90 to be processed into the above-mentioned space, control the second clamping end 41 to clamp the workpiece 90, and the first clamping end 21 is in a loose state at this time, and then control the pushing module 30 to drive the second clamping module 40 to move up, and then drive the workpiece 90 to move up through the second clamping end 41 until it protrudes out of the predetermined height of the first clamping end 21 (in some cases, it can also be set as: taking the supporting base plate 11 as the supporting reference, when the rod-shaped workpiece 90 to be processed is placed in the above-mentioned space, the initial position of the rod-shaped workpiece 90 is the predetermined height protruding from the first clamping end 21), at this time, the first clamping end 21 clamps the workpiece 90, and the second clamping module 40 releases the workpiece, and gradually resets under the action of the pushing module 30, leaving enough space for the CNC processing of the workpiece to avoid interfering with the CNC processing, and then the protruding part of the workpiece 90 is processed by CNC processing; after the processing is completed, under normal circumstances, there is only a few connecting dimensions between the processed finished product and the unprocessed raw material. Then, the moving module 50 drives the unloading clamping module 60 to move from the side close to the second support member 13 to the processed finished product through the moving part 51, and automatically clamps the finished product. Finally, the moving module 50 is reset, and drives the unloading clamping module 60 with the finished product to move rightward, and the finished product is easily torn off from the raw material, and then the clamped finished product is unloaded into the material storage bin 141 to complete the automatic unloading. In the process of resetting the moving module 50, the unloading clamping module 60 is clamped by the third clamping end 61. The finished product is automatically and easily torn off from the rod-shaped workpiece 90 raw material; after the finished product is removed, the first clamping end 21 is automatically loosened, and the second clamping end 41 clamps the rod-shaped workpiece 90 again, and then, under the action of the pushing module 30, the second clamping end 41 and the workpiece 90 clamped by the second clamping end 41 are pushed to move up a predetermined distance synchronously, and protrude again to a predetermined height of the first clamping end 21, so as to provide CNC processing for the second finished product, and so on, and the processing is continued until the entire rod-shaped workpiece 90 raw material is completely processed.

[0047] In this way, during the processing of the rod-shaped workpiece 90, it is only necessary to manually put in the raw materials of the rod-shaped workpiece 90. Under the action of the device, the raw materials can be automatically clamped and fed, and the finished products can be automatically unloaded after processing. The whole process is automated. Generally, for the processing of the rod-shaped workpiece 90 with a processing time of two hours, the man-machine ratio can be increased from the original 1:3 to 1:60, which greatly saves labor costs. It cooperates with CNC processing to achieve fully automated processing, effectively improves work efficiency, and effectively reduces personnel safety risks. With a small amount of manual working hours, a small number of personnel, and fewer similar equipment, the product quality and product processing quantity can be effectively improved.

[0048] Preferably, combined Figure 3 The first clamping end 21 includes two groups of the first fixed blocks 211 and the first moving blocks 212, wherein the two groups of the first fixed blocks 211 and the first moving blocks 212 are symmetrically arranged in the width direction of the supporting base plate 11, and the two first fixed blocks 211 are respectively close to the edge of the fixed plate 14, and at the same time, two corresponding unloading clamping modules 60 are arranged, wherein the third clamping end 61 on each unloading clamping module 60 corresponds to each group of the first clamping cavities 201. In this way, the number of workpieces 90 that can be processed can be doubled on the basis of the original equipment, further improving the work efficiency.

[0049] Preferably, a support limit block 111 is provided on the top of the support base plate 11, facing the material containing channel, for supporting the rod-shaped workpiece 90 to be processed to a certain height, ensuring that the rod-shaped workpiece 90 can be processed to the maximum extent and reducing the amount of waste material. At the same time, a groove suitable for placing the rod-shaped workpiece 90 is provided on the top of the support limit block 111, for limiting and positioning the rod-shaped workpiece 90 when the rod-shaped workpiece 90 is placed.

In addition, it does not affect the pushing module 30 pushing the second clamping module 40 to drive the workpiece 90 to move upward. A guide column 32 is arranged between the fixed plate 14 and the guide plate 31, wherein one end of the guide column 32 is fixedly arranged on the fixed plate 14, and the other end of the guide column 32 protrudes to the bottom of the guide plate 31 and is installed with a fastening nut 321. At the same time, a nut groove for accommodating the fastening nut 321 is arranged at the bottom of the guide plate 31, so that the guide plate 31 and the second clamping module 40 connected to the guide plate 31 can be guided by the guide column 32 to ensure that they can move up and down in a directional manner, improve the processing accuracy of the workpiece 90, and avoid damage to the workpiece 90. Through the cooperation of the fastening nut 321 and the nut groove, the guide plate 31 and the second clamping module 40 on the guide plate 31 can be further limited on the basis of the driving of the pushing module 30 to avoid them moving down too far and damaging the pushing module 30.

[0051] More preferably, in combination Figure 3The first clamping module 20 includes a first cylinder 22, a first wedge block 23, two first fixed blocks 211, two first moving blocks 212, a first guide block 24 and a sealing plate 25, wherein the first cylinder 22 is fixedly arranged on the top of the fixed plate 14, wherein the first wedge block 23 is detachably connected to the output end of the first cylinder 22, wherein the first wedge block 23 has a symmetrical first inclined surface structure 231 on both sides of the width direction, wherein the two first moving blocks 212 cooperate with the first wedge block 23 on one side, and a first groove 203 suitable for clamping the rod-shaped workpiece 90 is provided on the other opposite side, so that the two first moving blocks 212 can be synchronously driven by the first wedge block 23 under the driving action of the first cylinder 22. The blocks 212 move toward the directions of the two first fixed blocks 211 respectively, thereby synchronously clamping the workpieces 90 in the two groups of the first clamping cavities 201, wherein the first guide block 24 is provided with a first guide groove 204 for directional movement of the two first movable blocks 212, and a moving channel 205 for directional movement of the first wedge block 23 and connected to the first guide groove 204, respectively providing a guiding effect for the first movable block 212 and the first wedge block 23, wherein the sealing plate 25 is sealed and arranged on the top of the first clamping end 21, for protecting the first clamping module 20, and preventing waste or debris generated during CNC machining from entering the first guide groove 204 and the moving channel 205 to affect the normal operation of the first clamping module 20.

[0052] More preferably, in combination Figure 5 The second clamping module 40 includes two second cylinders 42, two second moving blocks 412 and two second fixed blocks 411, wherein the second cylinders 42, the second moving blocks 412 and the second fixed blocks 411 are symmetrically distributed in the width direction, wherein the second moving blocks 412 and the second fixed blocks 411 constitute the second clamping end 41, wherein the second moving block 412 is provided with a second groove 401 suitable for clamping the rod-shaped workpiece 90 on one side close to the second fixed block 411, so that the two second cylinders 42, the two second moving blocks 412 and the two second fixed blocks 411 cooperate with the first clamping module 20 to synchronously clamp or release the workpieces 90 in the two groups of first clamping cavities 201.

[0053] Further preferably, the material storage bin 141 is arranged on the fixed plate 14 in a manner that it can move in the width direction, so that after all processing is completed, all the finished products processed in the two groups of the first clamping cavities 201 can be transferred to the next process or the next workstation at one time through the material storage bin 141. At the same time, the bottom of the fixed plate 14 is provided with a second guide groove 142 suitable for accommodating the material storage bin 141, and at the same time, the top of the fixed plate 14 is provided with discharge ports (blocked by protective covers) facing the first clamping cavities 201 respectively. The reason why the material storage bin 141 is arranged to move in the width direction is mainly because the two groups of the first clamping cavities 201 are arranged side by side in the width direction, and in the length direction, the workpiece 90 in each first clamping cavity 201 of each group of the first clamping cavities 201 can be discharged into the material storage bin 141 through the discharge port through the discharge clamping module 60 and the moving module 50. In addition, the pushing module 30 is fixedly connected to the first support member 12, that is, the pushing module 30 is close to the first support member 12, so that a larger space can be reserved on the side close to the second support member 13, so that the material storage bin 141 can extend downward to a greater depth within the reserved space, thereby accommodating more finished products, reducing the number of manual transfers of finished products, and improving work efficiency and the man-machine ratio.

[0054] Further preferably, the device further comprises a protection module 70 which is controllably connected to a CNC machining center. Figure 8 The protection module 70 includes a protection cylinder 71 and a protection cover plate 72, wherein the protection cylinder 71 is fixedly arranged on the side of the second support member 13 away from the first support member 12, and has a telescopic end output along the length direction, wherein the protection cover plate 72 is U-shaped, and is composed of a first protection cover 721, a second protection cover 722 and a connecting plate 723, wherein the connecting plate 723 is fixedly connected to the telescopic end of the protection cylinder 71, and the first protection cover 721 and the second protection cover 722 are respectively opposite to the two discharge ports, which are used to cover the discharge ports during CNC processing to prevent processing waste or debris from entering the material storage bin 141 and affecting the quality of the product. In addition, once waste or debris enters the material storage bin 141, it will inevitably increase the cleaning work of subsequent workstations, affecting work efficiency and processing progress. The U-shaped design of the protective cover 72 is mainly based on the distribution positions of the two groups of first clamping cavities 201 and the two discharge ports. It can not only perfectly protect the two discharge ports, but also make way for the mobile cylinder 52 in the mobile module 50 to avoid installation space, making the overall structure of the device more compact. At the same time, it can also save raw materials and reduce waste of resources.

[0055] Further preferably, a second guide block 143 is symmetrically arranged on the top of the fixed plate 14 on the inner side relative to the first protective cover 721 and the second protective cover 722. At the same time, the second guide block 143 is provided with an L-shaped or arc-shaped guide portion, which is used to further ensure the accuracy of the moving direction of the protective cover plate 72 on the basis of the protective cylinder 71, so as to avoid the problem of the protective discharge port not being in place, which affects the quality of the finished product and reduces the work intensity and work efficiency.

[0056] In some cases, for CNC machining of different rod-shaped workpieces, the connection size between the finished product and the raw material after machining may be relatively large, reaching more than ten or even dozens of threads. It is difficult to forcibly tear the finished product from the raw material by simply relying on the movement of the unloading clamping module 60 and the moving module 50. In serious cases, it may affect the quality of the finished product or even damage the finished product. Therefore, it is further preferred to combine Fig. 9 The device also includes a linear separation module 80 which is controllably connected to the CNC machining center, wherein the linear separation module 80 includes two separation cylinders 81 and a cutter corresponding to the output end of the separation cylinder 81, wherein the separation cylinder 81 is fixedly arranged on the fixed plate 14 and close to the first support 12, and at the same time, the output end of the separation cylinder 81 extends in the direction of the second support 13, and the two cutters are respectively facing the two groups of the first clamping chambers 201, and are located on the side of the first clamping chamber 201 close to the first support 12, so that after the CNC machining is completed, the unloading clamping module 60 clamps the finished product, and at the same time, the first clamping module 20 clamps the raw material, and the separation cylinder 81 drives the cutter to perform the cutting operation at the connection between the finished product and the raw material. Because the connection size between the finished product and the raw material is in the case of more than ten or dozens of threads, although it is not easy to tear off, the connection size is still relatively small, and the cutter can easily cut the connection, and the requirements for the cutter and the separation cylinder 81 are not very large. In addition, a cutter seat 82 is installed at the output end of the separation cylinder 81 for installing the cutter and facilitating replacement of a new cutter when problems occur with the cutter, such as reduced cutting accuracy, or when a cutter of corresponding material needs to be replaced for processing raw materials of different materials.
