Description

Technical Field

[0001] The invention relates to the technical field of milling machine equipment, in particular to a milling machine device for processing precision parts. Background Art

[0002] Mechanical parts refer to the individual parts that cannot be separated in a machine. They are the basic components of the machine and the basic units in the mechanical manufacturing process. The manufacturing process generally does not require assembly. During the mechanical assembly process, the parts are first assembled into components (component assembly) and then enter the general assembly. Some components are also assembled with other components and parts into larger components before entering the general assembly. A larger component assembled from several sub-components and having independent functions is called an assembly in the automotive and some other mechanical industries.

[0003] In the process of parts processing, milling machine equipment is usually used to process the parts so that the processed parts meet the work requirements.

[0004] As is known, a milling machine is a widely used machine tool. It can process planes, grooves, toothed parts, spiral surfaces and various curved surfaces. In addition, it can also be used for processing the surface of a rotating body, inner holes and cutting. When the milling machine is working, the machine is installed on a workbench or an accessory such as a dividing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or the milling head, and the machine can obtain the required processing surface.

[0005] In the milling machine device of the prior art, a large amount of flying chips will be generated due to cutting when machining mechanical parts. These flying chips will not only hinder the subsequent machining of the workpiece body, but may also cause certain harm to the staff. In order to solve the above technical problems, many related patents have been proposed in the prior art, including a Chinese patent with application number 202420319881.2 and authorization announcement number CN221849412U, entitled "A milling machine device for machining mechanical parts". The above patent discloses a milling machine device for machining mechanical parts, including a milling machine, wherein the upper surface of the milling machine is fixedly connected to two support plates, a clamping assembly is arranged on the support plate, a cavity is opened inside the milling machine, a partition is fixedly connected to the inner wall of the cavity, a motor is fixedly connected to the upper surface of the partition, a gear is fixedly connected to the output end of the motor, a through groove extending into the cavity is opened on the upper surface of the milling machine, an outer gear ring is rotatably connected to the inner part of the through groove, the outer gear ring is meshed with the gear, a second support plate is rotatably connected to the inner wall of the outer gear ring, and a feeding trough communicating with its lower surface is opened on the upper surface of the second support plate.

[0006] Another example is the Chinese patent with application number 202120723609.7, authorization announcement number CN215147245U, and name "A milling machine for processing mobile phone parts". The above patent discloses a milling machine for processing mobile phone parts, including a milling machine, a first electric slide rail is provided on one side of the top of the milling machine, a cross plate is slidably connected to one side of the first electric slide rail, a working area is provided in the middle position of the top of the milling machine, a metal hollow mesh is movably connected in the middle position of the working area, and electric push rods are fixedly connected on both sides of the outside of the milling machine. In the above patent, fixed rods, springs and arc-shaped clamps are used to clamp and fix the parts, so that the parts will not shake when the milling cutter is working, reducing the occurrence of defective products.

[0007] In the prior art such as the above patent, the processing quality of the workpiece body can be improved to a certain extent, and the waste chips after processing can be easily cleaned, which can meet the daily processing needs to a certain extent. It is known that in the prior art such as the above patent, the workpiece body is held by hand before the parts are processed, and the workpiece body is placed in a predetermined processing station and fixed using a clamping mechanism, and then the workpiece body is processed using a milling cutter mechanism. Therefore, in order to meet the needs of daily work, parts processing is usually carried out in large quantities. However, the loading method in the prior art, such as the above-mentioned patent, is generally that the operator manually loads the material, and then manually drives the fastening mechanism to fix the workpiece body. At this time, the operator needs to observe and wait beside the equipment. After the workpiece body is processed, the workpiece body is removed and the next workpiece is loaded and fixed again. This method increases the workload and affects the work efficiency of the equipment; another loading method uses a CNC program to control the mechanical arm to clamp the workpiece body for loading, and then uses the CNC program to control the fastening mechanism to fix the workpiece body. After the milling cutter mechanism completes the processing of the workpiece body, the complex CNC program controls the mechanical arm to unload the workpiece body and then clamps the workpiece body to be processed for loading again. Although this loading method can reduce safety hazards and reduce the workload of the operator, the use of expensive mechanical arms and the use of complex CNC control mechanical arms and fastening mechanisms will lead to a significant increase in the processing cost of the workpiece body. Based on this, how to realize the automatic loading of the workpiece body on a device and passively realize the fastening mechanism to fix the workpiece body is a technical problem that needs to be solved urgently.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1-Figure 19The present invention provides a technical solution: a milling machine device for precision parts processing, comprising a milling machine body 1 and a bearing plate 2 vertically slidably connected to the milling machine body 1, and a servo cylinder 4 for driving the bearing plate 2 to slide vertically is arranged on the milling machine body 1; a milling cutter mechanism 3 for processing a workpiece body 6 is installed on the bearing plate 2 through a servo mechanism, a mounting frame 5 for storing the workpiece body 6 is installed on the milling machine body 1, and a clamping and loading member 7 is arranged on the milling machine body 1, and the clamping and loading member 7 includes a mounting block 71 slidably connected to the milling machine body 1, and an elastic clamping sheet 72 for clamping the workpiece body 6 is arranged on the mounting block 71; the milling machine body 1 A fastening mechanism 11 is arranged on the bed body 1, and the mounting block 71 is connected to the fastening mechanism 11 through a pressure mechanism 12, and a linkage mechanism 10 is arranged between the supporting plate 2 and the mounting block 71; the first station: in the stroke in which the servo cylinder 4 drives the supporting plate 2 to slide upward, the linkage mechanism 10 drives the mounting block 71 to drive the elastic clamping piece 72 to clamp the workpiece body 6; the second station: in the stroke in which the servo cylinder 4 drives the supporting plate 2 to slide downward, the linkage mechanism 10 drives the mounting block 71 to drive the workpiece body 6 to slide away from the side of the mounting frame 5, and the pressure mechanism 12 drives the fastening mechanism 11 to fix the workpiece body 6.

[0047] Specifically, the milling machine device for precision parts processing includes a milling machine body 1 and a bearing plate 2 vertically slidably connected to the milling machine body 1, and multiple groups of support members are arranged on the bottom of the milling machine body 1, and each support member is provided with an anti-skid pad to improve the stability of the entire milling machine device during operation and improve the processing quality of the workpiece body 6. At the same time, the bearing plate 2 slides vertically on the milling machine body 1, which is convenient for the installation and use of the milling cutter mechanism 3. In order to improve the stability of the milling cutter mechanism 3 when sliding, a limited position component is arranged between the bearing plate 2 and the milling machine body 1 to meet the working needs. A servo cylinder 4 for driving the bearing plate 2 to slide vertically is arranged on the milling machine body 1, which provides a power source for the vertical sliding of the bearing plate 2, and is used to control the vertical sliding of the milling cutter mechanism 3 to meet the processing use of the milling machine device for the workpiece. The milling cutter mechanism 3 for processing the workpiece body 6 is installed on the bearing plate 2 through a servo mechanism, and the milling cutter mechanism 3 is a prior art, and its structure and working principle are not repeated here. At the same time, a servo mechanism is provided between the milling cutter mechanism 3 and the carrier plate 2, which is used to control the milling cutter mechanism 3 to slide along the X-axis, Y-axis and Z-axis directions on the milling machine body 1, so as to facilitate the processing of the workpiece. The servo mechanism is a prior art and will not be described in detail here. A processing station is provided on the milling machine body 1 below the milling cutter mechanism 3.

[0048] The milling machine body 1 is provided with a mounting frame 5 for storing the workpiece body 6. Specifically, the milling machine body 1 is provided with a feeding trough 21, and the feeding trough 21 is arranged between the mounting frame 5 and the processing station in an inclined shape. Therefore, when the workpiece body 6 slides from the mounting frame 5 to the processing station, the clamping and loading member 7 at this moment will be located below the workpiece body 6, and will not affect the subsequent processing of the workpiece body 6. The milling machine body 1 is provided with a clamping and loading member 7 for clamping and loading the workpiece located inside the mounting frame 5. Specifically, the clamping and loading member 7 includes a mounting block 71 slidably connected to the milling machine body 1, and the mounting block 71 is provided with an elastic clamping sheet 72 for clamping the workpiece body 6. The elastic clamping sheet 72 is provided with an arc shape at one end close to the workpiece body 6, so that the workpiece body 6 can be better clamped. During operation, when the mounting block 71 approaches one side of the workpiece body 6, the workpiece body 6 is clamped and fixed by the elastic clamping sheet 72, and then the mounting block 71 can drive the workpiece body 6 to slide to the processing station for processing. Therefore, in the present application, it is only necessary to place the workpiece body 6 to be processed inside the installation frame 5, wherein the size of the installation frame 5 is set according to the environmental requirements.

[0049] The milling machine body 1 is provided with a fastening mechanism 11, which is used to fix the workpiece body 6, so as to improve the stability of the workpiece body 6 during processing, avoid the loosening of the workpiece body 6 during processing, improve the processing quality of the workpiece, and achieve better use effect. The mounting block 71 is connected to the fastening mechanism 11 through a pressure mechanism 12, that is, the mounting block 71 drives the fastening mechanism 11 to fix the workpiece body 6 through the pressure mechanism 12 during the sliding stroke, and there is no need to set a separate driving source to drive the fastening mechanism 11 to fix the workpiece, but the workpiece is fixed completely passively, which greatly improves the practicality of the milling machine device. At the same time, a linkage mechanism 10 is provided between the bearing plate 2 and the mounting block 71. At this moment, when the servo cylinder 4 drives the bearing plate 2 to slide downward, the mounting block 71 can be driven to slide through the linkage mechanism 10.

[0050] During the working process, the servo cylinder 4 drives the carrier plate 2 to slide downward and upward to produce different working positions, specifically;

[0051] At the first station, the servo cylinder 4 drives the carrier plate 2 to slide upwards, and drives the mounting block 71 to drive the elastic clamping piece 72 to clamp the workpiece body 6 through the linkage mechanism 10. Specifically, after the workpiece body 6 is processed, the servo cylinder 4 needs to be used to drive the carrier plate 2 to reset upwards. During the upward sliding stroke of the carrier plate 2, the mounting block 71 will be driven to slide toward the side close to the mounting frame 5. When the mounting block 71 approaches the side of the workpiece body 6, the workpiece body 6 is clamped and fixed by the elastic clamping piece 72, which facilitates the loading of the next workpiece body 6 to be processed and meets the work needs.

[0052] Second workstation: During the downward sliding stroke of the support plate 2 driven by the servo cylinder 4, the linkage mechanism 10 drives the mounting block 71 to drive the workpiece body 6 to the side away from the mounting frame 5, and the pressure mechanism 12 drives the fastening mechanism 11 to fix the workpiece body 6. Specifically, after the elastic clamping sheet 72 clamps and fixes the workpiece body 6, the servo cylinder 4 drives the support plate 2 to slide downward, and during the downward sliding stroke, the support plate 2 drives the mounting block 71 through the linkage mechanism 10 to slide the workpiece body 6 to a predetermined workstation through the elastic clamping member, so as to facilitate the subsequent processing of the workpiece. During the sliding stroke of the mounting block 71, the fastening mechanism 11 is driven by the pressure mechanism 12 to fix the workpiece, and there is no need to set up a separate driving source to drive the fastening mechanism 11 to fix the workpiece, but the workpiece is fixed completely passively, which greatly improves the practicality of the milling machine device. At this moment, when the carrier plate 2 slides upward, the workpiece body 6 is clamped, and when the carrier plate 2 slides downward, the loading of the workpiece body 6 can be passively realized, and in the workpiece loading stroke, the clamping and fixing of the workpiece is passively realized through the cooperation between the pressure mechanism 12 and the fastening mechanism 11, which can improve the stability of the workpiece body 6 in the subsequent processing process. Compared with the prior art, the present application does not need to adopt manual loading, and there is no need to drive the fastening mechanism 11 to fix the workpiece separately after loading, thereby improving work efficiency and reducing the occurrence of safety hazards. Compared with the prior art that uses expensive procedures and mechanical arms to realize loading, reducing the use of driving sources can greatly reduce production costs, and it is more convenient for later inspection and maintenance, etc., to meet work needs.

[0053] In the embodiment provided by the present invention, a feeding mechanism is also provided on the milling machine body 1, and the feeding mechanism includes a mounting frame 13 slidably connected to the milling machine body 1, and a clamping and feeding member 14 for clamping the workpiece body 6 for feeding is provided inside the mounting frame 13. By providing the clamping and feeding member 14, after the workpiece body 6 is processed, the workpiece is clamped from the processing station by the clamping and feeding member 14, and the processed workpiece body 6 is passively fed as the mounting frame 13 slides, thereby further improving the practicality of the milling machine device and meeting the work needs. A driving member 17 for driving the mounting frame 13 to slide is provided inside the milling machine body 1, and the driving member 17 can be used to drive the mounting frame 13 to slide on the milling machine body 1 according to the work needs, so that the use effect is better. The mounting block 71 is connected to the driving member 17 through an intermittent transmission mechanism 18, so that during use, the movement of the driving member 17 is realized through the intermittent linkage mechanism 10. Specifically, in actual use, after the workpiece body 6 is processed, the servo cylinder 4 drives the carrier plate 2 to slide upward. At this moment, the carrier plate 2 drives the mounting block 71 to slide toward the side close to the mounting frame 5 through the linkage mechanism 10. The mounting frame 13 is driven to slide toward the side of the workpiece body 6 through the cooperation between the intermittent transmission mechanism 18 and the driving member 17. The clamping blanking member 14 is used to blank the processed workpiece body 6, thereby realizing passive blanking of the processed workpiece body 6, thereby further improving the practicability of the milling machine device and meeting work needs.

And an elastic part 8 is provided inside the mounting frame 5. Specifically, the elastic part 8 includes a pressure plate 82 slidably connected to the inside of the mounting frame 5, and a pressure spring 81 is provided between the pressure plate 82 and the mounting frame 5, and the elastic force of the pressure spring 81 drives the pressure plate 82 to press the multiple groups of workpieces. A release portion is provided between the mounting block 71 and the two blocking blocks 91, and the specific release portion includes a release block 95 fixedly connected to the mounting block 71, and a release groove 94 is provided on the blocking block 91. When the supporting plate 2 slides upward, the mounting block 71 will be driven to slide toward the side close to the mounting frame 5, and the mounting block 71 will approach the side of the workpiece body 6. At this moment, the release block 95 will abut against the release groove 94. As the mounting block 71 continues to slide, the two blocking blocks 91 will be driven to move away from each other under the elastic force of the blocking spring 93. At this moment, the workpiece body 6 will slide towards the elastic clamping piece 72 under the elastic action of the elastic portion 8, and will be clamped by the elastic clamping piece 72 to meet the working needs.

[0055] In the embodiment provided by the present invention, the linkage mechanism 10 includes a linkage rod 101 rotatably connected to the milling machine body 1, a first linkage gear 102 and a second linkage gear 103 are installed on the linkage rod 101, and a driving rack 105 is fixedly connected to the bearing plate 2, wherein the driving rack 105 is fixedly connected to a limit bar, and vertically slides on the milling machine body 1 to connect the limit groove, which can improve the stability of the bearing plate 2 when it slides vertically, and the use effect is higher and better. The driving rack 105 is meshed with the first linkage gear 102, and the mounting block 71 is fixedly connected with a force rack 104 meshed with the second linkage gear 103 through a connecting block. When the bearing plate 2 slides vertically, it will drive the first linkage gear 102 to rotate through the driving rack 105, and then drive the linkage rod 101 to rotate. When the linkage rod 101 rotates, it drives the mounting block 71 to slide through the second linkage gear 103 and the force rack 104, meeting the working needs.

[0056] In the embodiment provided by the present invention, specifically, the fastening mechanism 11 is slidably connected to the bearing frame 112 on the milling machine body 1, and each bearing frame 112 is slidably connected to a plurality of sets of fastening blocks 111 through stoppers 113. Specifically, the stoppers 113 include guide rods 1131 fixedly connected to the bottom of the fastening blocks 111, and the guide rods 1131 slide inside the bearing frame 112, and a guide groove 1132 is provided on the milling machine body 1. When the bearing frame 112 slides inside the milling machine body 1, the guide rods 1131 at this moment slide inside the guide groove 1132, and the workpiece can be clamped and fixed and the workpiece can be unlocked according to work needs. A guide block 114 is fixedly connected to the bottom of each support frame 112, and a force block 115 is fixedly connected to the guide block 114; the pressure mechanism 12 drives the guide block 114 to drive the support frame 112 to slide through the force block 115, and a first return spring 116 is provided between each support frame 112 and the milling machine body 1. Therefore, when it is necessary to fix the workpiece body 6, when the pressure mechanism 12 drives the force block 115 to slide, the support frame 112 will be driven to slide through the cooperation between the force block 115 and the guide block 114. When the two support frames 112 slide close to each other, the limiting member 113 drives multiple sets of fastening blocks 111 to fix the workpiece body 6, thereby achieving stability during the processing of the workpiece body 6 and meeting the working needs. Reference Fig.18Specifically, each supporting block is slidably connected with an abutment plate 1111, and an abutment spring 1112 is provided between each abutment plate 1111 and the fastening block 111, and a positioning space is formed between multiple groups of abutment plates 1111. Therefore, during use, when the fastening block 111 is needed to fix the workpiece body 6, the abutment plate 1111 at this moment is located inside the fastening block 111. When the workpiece body 6 is processed, in the process of multiple groups of fastening blocks 111 moving away from each other, the abutment plate 1111 at this moment positions the workpiece body 6 under the positioning of the abutment spring 1112, so as to avoid the workpiece body 6 from tipping over when the fastening block 111 just moves away from the workpiece body 6, so as to avoid affecting the subsequent unloading of the workpiece body 6, and further improve the practicality of the milling machine device. At the same time, when there is no pressure mechanism 12 acting on the force block 115, the elastic force of the first return spring 116 at this moment will drive the two supporting frames 112 away from each other during the recovery of elastic deformation, so that the supporting frame 112 drives multiple groups of fastening blocks 111 to slide, unlocking the workpiece body 6 and facilitating the subsequent unloading of the workpiece body 6.

[0057] In the embodiment provided by the present invention, the pressure mechanism 12 includes a rotating plate 121, wherein the rotating plate 121 is rotatably connected to the milling machine body 1 through a rotating rod 122; an abutment portion 124 is provided on one end of the rotating plate 121, and the mounting block 71 intermittently abuts against the abutment portion 124. A pressure portion 125 is provided on one end of the rotating rod 122 away from the abutment portion 124, and the pressure portion 125 intermittently abuts against the force block 115. Specifically, a wedge-shaped groove is provided on the force block 115, and the force block 115 abuts against the wedge-shaped groove, and the guide block 114 is driven by the force block 115 to drive the bearing frame 112 to slide inside the milling machine body 1. Therefore, when the workpiece body 6 needs to be fixed, the servo cylinder 4 at this moment drives the supporting plate 2 to slide downward. During the downward sliding stroke of the supporting plate 2, the first linkage gear 102 is driven to rotate by driving the rack 105, and then the linkage rod 101 is driven to rotate. When the linkage rod 101 rotates, the mounting block 71 is driven to slide through the second linkage gear 103 and the force-bearing rack 104. At this moment, the clamping and loading part 7 on the mounting block 71 has clamped the workpiece body 6, and slides toward the side of the processing station during the sliding stroke of the mounting block 71. When the mounting block 71 is in a continuous sliding process, the abutting portion 124 will abut against the mounting block 71. When the mounting block 71 is in a continuous sliding process, the abutting portion 124 will drive the rotating plate 121 to rotate. During the rotating stroke of the rotating plate 121, the pressure portion 125 abuts against the force block 115, and then the force block 115 can drive the guide block 114 to drive the bearing frame 112 to slide inside the milling machine body 1. The cooperation of the limiter 113 drives the fastening blocks 111 to approach each other to fix the workpiece body 6. After the workpiece body 6 is fixed, the servo mechanism on the bearing plate 2 is used to control the milling cutter mechanism 3 to process the workpiece to meet the work needs. Specifically, a second reset spring 123 is also provided between the rotating plate 121 and the milling machine body 1. The elastic force of the second reset spring 123 drives the rotating plate 121 to be inclined, so that it is convenient for the mounting block 71 to contact the abutting portion 124 on the rotating plate 121 again next time, and the use effect is better.

[0058] In the embodiment provided by the present invention, the clamping blanking piece 14 includes a clamping plate 141 slidably connected to both sides of the mounting frame 13, and a connecting spring 144 is provided between the clamping plates 141 on both sides, and the elastic force of the connecting spring 144 drives the two clamping plates 141 to approach each other. Specifically, both clamping plates 141 are provided with an adapting groove 142 for fixing the workpiece body 6. At the same time, both clamping plates 141 are also provided with an inclined groove, so as to better clamp and fix the workpiece body 6. The mounting frame 13 is provided with a positioning groove, and each clamping plate 141 is also provided with a limit block 143, and each limit block 143 is respectively slidably connected in the corresponding positioning groove, so as to improve the stability of the clamping plate 141 when sliding. A triggering part for driving the two clamping plates 141 away from each other is provided between the milling machine body 1 and the two clamping plates 141. The specific triggering part includes a triggering block 16 fixedly connected to the milling machine body 1. A triggering groove 15 is provided on the two clamping plates 141. When the two clamping plates 141 slide to the position of the triggering block 16, the two clamping plates 141 can be driven away from each other through the contact between the triggering block 16 and the triggering groove 15, so that the workpiece body 6 is separated from the two clamping plates 141, and the workpiece body 6 is unloaded. The driving member 17 includes a reciprocating screw rod 171 rotatably connected to the milling machine body 1, and a driving block 172 threadedly connected to the reciprocating screw rod 171 is fixedly connected to the bottom of the mounting frame 13. Therefore, when the workpiece body 6 needs to be cut, the reciprocating screw 171 is driven to rotate at this moment. When the reciprocating screw 171 rotates, the mounting frame 13 is driven to slide horizontally on the milling machine body 1 through the driving block 172, and the workpiece body 6 after processing is clamped by the cooperation between the clamping plate 141 and the connecting spring 144. After that, the reciprocating screw 171 continues to rotate, and the driving block 172 will be reset. After that, the two clamping plates 141 will abut against the trigger block 16 on the milling machine body 1. As the driving block 172 continues to slide, the trigger block 16 will drive the two clamping plates 141 away from each other through the trigger groove 15, and then the workpiece will be separated from the clamping blanking piece 14. The intermittent transmission mechanism 18 is used to drive the reciprocating screw 171 to rotate. Specifically, when the bearing plate 2 slides upward, the intermittent transmission mechanism 18 can drive the reciprocating screw 171 to rotate, and when the bearing plate 2 slides downward, it will not drive the reciprocating screw 171 to rotate, so as to avoid motion interference and meet the work needs. The length of the thread on the reciprocating screw 171 and the pitch of the thread can be set according to work needs, so that when the reciprocating screw 171 continues to rotate, the mounting frame 13 can drive the clamping and blanking member 14 to clamp and blank the workpiece body 6.

[0059] In the embodiment provided by the present invention, the intermittent transmission mechanism 18 includes a first support rod 181 and a second support rod 182 which are rotatably connected to the milling machine body 1, and the first support rod 181 is connected to the reciprocating screw rod 171 through a gear set 185. Specifically, the gear set 185 includes a first bevel gear installed on the first support rod 181, and a second bevel gear is installed on the reciprocating screw rod 171, and the first bevel gear is meshed with the second bevel gear. A spur gear 184 is fixedly connected to the second support rod 182, and a linkage rack 186 is fixedly connected to the force rack 104, and the linkage rack 186 is meshed with the spur gear 184; the first support rod 181 and the second support rod 182 are connected through an intermittent connector 183. The intermittent connecting member 183 includes a connecting cylinder 1831 fixedly connected to the second support rod 182, a connecting rod 1832 fixedly connected to the first support rod 181 is installed on the connecting cylinder 1831, and a plurality of bases 1833 are fixedly connected to the connecting rod 1832, each base 1833 is provided with a ratchet 1834, and specifically, a limited position unit is provided between the ratchet 1834 and the base 1833, so that the ratchet 1834 can only be in a half-rotation state, refer to Fig.16 The ratchet 1834 can only turn in the direction of the arrow and cannot rotate in the opposite direction. A torque spring is provided between the ratchet 1834 and the base 1833, and a tooth groove 1834 is provided on the connecting tube 1831. The elastic force of the torque spring drives the ratchet 1834 to be clamped in the tooth groove 1834.

[0060] Therefore, during use, when the supporting plate 2 slides downward, the linkage mechanism 10 drives the mounting block 71 to clamp the workpiece and then load the material. The mounting block 71 will drive the load-bearing rack 104 to slide during its sliding stroke. At this moment, the load-bearing rack 104 drives the linkage rack 186 to slide, so that the linkage rack 186 drives the spur gear 184 to rotate, and then drives the second support rod 182 to rotate. At this moment, the second support rod 182 drives the connecting tube 1831 to rotate, and when the connecting tube 1831 rotates, the arc-shaped portion of the tooth groove 1834 abuts against the arc-shaped portion of the ratchet 1834, thereby driving the ratchet 1834 to flip over with the base 1833 as the axis. At this moment, the connecting rod 1832 cannot be driven to rotate, so the clamping and unloading part 14 will not be driven to slide through the driving member 17. On the contrary, after the workpiece body 6 is processed, the servo cylinder 4 drives the carrier plate 2 to reset upward, so that when the mounting block 71 is driven to slide toward the side of the mounting frame 5 through the linkage mechanism 10, the force-bearing rack 104 drives the linkage rack 186 to slide, so that the linkage rack 186 drives the spur gear 184 to rotate, and then drives the second support rod 182 to rotate. At this moment, the second support rod 182 drives the connecting tube 1831 to rotate. At this moment, the straight part of the tooth groove 1834 on the connecting tube 1831 abuts against the ratchet 1834. At this moment, the connecting rod 1832 must be driven to rotate through the ratchet 1834 and the base 1833. When the connecting rod 1832 rotates The reciprocating screw 171 is driven to rotate by the gear set 185. When the reciprocating screw 171 rotates, the driving block 172 drives the mounting frame 13 to slide horizontally on the milling machine body 1. The clamping plate 141 and the connecting spring 144 cooperate to clamp the processed workpiece body 6. Then, the reciprocating screw 171 continues to rotate, and the driving block 172 will be reset. Then, the two clamping plates 141 will abut against the trigger block 16 on the milling machine body 1. As the driving block 172 continues to slide, the trigger block 16 will drive the two clamping plates 141 away from each other through the trigger groove 15. Then, the workpiece will be detached from the clamping blanking piece 14, thereby improving the blanking efficiency of the workpiece body 6.

[0061] In the embodiment provided by the present invention, a receiving plate 19 is slidably connected to the milling machine body 1, and the receiving plate 19 is inclined. The receiving plate 19 is connected to the mounting frame 13 by a transmission part 22. That is, during the unloading process of the workpiece body 6, the receiving plate 19 is driven to slide out of the milling machine body 1 by the transmission part 22, and conversely, the receiving plate 19 is located inside the milling machine body 1, so as to avoid affecting the use of the entire milling machine device and meet the work needs. In addition, an inclined unloading trough 20 is provided on the milling machine body 1, so as to facilitate the unloading of the workpiece body 6 in cooperation with the receiving plate 19. When the reciprocating screw 171 drives the clamping unloading part 14 to clamp the workpiece body 6 and then reset, the receiving plate 19 is driven to slide out of the milling machine body 1 by the transmission part 22, so as to unload the workpiece body 6 after processing, thereby improving the convenience of unloading the workpiece body 6. A positioning block 221 is fixedly connected to the material receiving plate 19, and a positioning spring 222 is arranged between the positioning block 221 and the milling machine body 1, wherein the elastic force of the positioning spring 222 drives the material receiving plate 19 to be located inside the milling machine body 1, thereby improving the stability of the material receiving plate 19 during installation. Meanwhile, the transmission part 22 includes a transmission gear 225 rotatably connected to the milling machine body 1, a first rack 223 is fixedly connected to the mounting frame 13, and a second rack 224 is slidably connected to the milling machine body 1, and the first rack 223 and the second rack 224 are respectively meshed on both sides of the transmission gear 225. The positioning block 221 is provided with a power groove, and a power block is fixedly connected to the second rack 224. When the mounting frame 13 clamps the processed workpiece body 6 with the blanking piece 14 and opens a reverse sliding motion, the second rack 224 is driven to slide through the cooperation between the first rack 223 and the transmission gear 225, and the receiving plate 19 is driven to slide out of the milling machine body 1 through the cooperation between the power block on the second rack 224 and the power groove. When the clamping plate 141 abuts against the trigger block 16, the processed workpiece body 6 just falls on the receiving plate 19 at this moment, and is loaded and unloaded from the milling machine body 1 through the blanking groove 20, which greatly improves the blanking efficiency of the workpiece body 6.
