Description

Technical Field

[0001] The invention relates to the technical field of shearing equipment, in particular to a shearing equipment for automobile interior metal parts. Background Art

[0002] Automotive interior metal parts refer to metal parts installed inside the car for decoration, function realization or structural support. They not only have decorative functions, but also play an important role in realizing various functions inside the car and providing structural support. In order to ensure that the metal parts can meet the assembly requirements of the car interior, they usually need to be precisely sheared. Shearing refers to the use of specific cutting tools or techniques to accurately cut metal parts according to installation requirements.

[0003] Most of the existing shearing operations for automotive interior metal parts still rely on manual shearing. However, due to the strict standards for metal part shearing, manual shearing often cannot achieve the ideal cutting accuracy, which leads to uneven shearing quality. Defects such as burrs are prone to appear on the sheared edges of metal parts, thereby reducing the shearing quality of metal parts, and further reducing the negative impact on subsequent processes such as painting of metal parts. In order to pursue shearing quality, manual shearing often lacks sufficient protective measures, which makes it easy for the flying metal debris during the shearing process to pose a direct threat to the operator. These flying metal debris may not only cause skin scratches, eye damage and other injuries, but may also be accidentally inhaled by the operator into the mouth and nose, thereby causing a negative impact on the operator's health and safety, and the practicality is not good.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The present invention can automatically complete the shearing of metal parts through the mutual cooperation of the metal pretreatment mechanism and the shearing mechanism, without manual shearing, thereby effectively ensuring the safety of the staff. At the same time, before the metal parts are sheared, the high-frequency electric field between the two groups of electrodes in the metal pretreatment mechanism can be used to soften the part of the metal part to be sheared, thereby reducing the difficulty of shearing the metal parts and effectively improving the service life of the cutter head in the shearing mechanism. Softening the part of the metal part to be sheared can avoid burrs on the metal part after shearing, thereby effectively improving the shearing quality of the metal parts. In addition, by using the setting of the cutter replacement component in the shearing mechanism, the cutter head can be automatically replaced after monitoring that the cutter head is worn to a certain extent. This mechanism of automatic cutter head replacement not only saves costs, but also greatly reduces the workload of maintenance personnel.

[0020] 2. The present invention can fill the upper cover with argon gas by setting an argon spraying assembly in the metal pretreatment mechanism. The argon gas between the two sets of electrodes can generate plasma at a certain generation rate under the action of a high-frequency electric field, and the metal parts can eliminate static electricity thereon by contacting with the plasma, thereby preventing the powder generated when shearing the metal parts from adhering to their surface, thereby effectively improving the quality of subsequent processing steps such as painting.

[0021] 3. The present invention can monitor and feedback the wear of the cutter head in real time by setting a gap sensor, so that the cutter head worn to a certain extent can be replaced in conjunction with the cutter replacement component, thereby effectively preventing the cutter head from affecting its shearing quality due to wear, and avoiding defects such as burrs, curling, and cracks on the metal parts being sheared, that is, it can ensure that the cutter head is in the best working condition each time it is used, thereby effectively ensuring the quality and stability of the shearing work.

[0022] 4. The present invention can provide overload protection for the shearing mechanism by arranging the disc spring and the contact in the cutter replacement assembly. When the force applied to the cutter head exceeds the elastic force of the disc spring (that is, the force applied to the cutter head is too large), the shearing operation on the metal part will be stopped urgently and the cutter head will be retracted. At the same time, an alarm will be issued to notify the maintenance personnel to check the equipment, so as to prevent the cutter head from breaking due to overload. On the one hand, preventing the cutter head from breaking can effectively ensure the service life of the cutter head. On the other hand, preventing the cutter head from breaking can avoid damage to the surface of the metal part, thereby ensuring the quality of subsequent processing procedures such as painting of the metal part. In addition, the setting of the lower cover and the upper cover can protect the safety of on-site personnel, that is, prevent the fragments of the cutter head from flying out and injuring on-site personnel.

[0023] 5. The present invention, through the setting of the material distribution and collection mechanism, can utilize the rotation of the flap in the distribution pipe to make different materials fall into different collection boxes, that is, the scraps sheared off the metal parts fall into the collection box one, and the replaced worn cutter heads fall into the collection box two. In order to maintain the good operation of the shearing equipment, the staff needs to clean the collection box one and the collection box two regularly. By separating and collecting the scraps and the cutter heads, not only the smooth operation of the equipment can be ensured, but also the workload of the staff can be greatly reduced, thereby improving the work efficiency of the staff.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figures 1 to 5The automobile interior metal parts shearing equipment comprises a base 1, a feed tube 5 and a lower cover 6 are fixedly mounted on the base 1, the lower cover 6 is detachably mounted on the top of the feed tube 5, and an upper cover 7 is fixedly mounted on the top of the lower cover 6, both sides of the upper cover 7 are penetrated with a feed port 73, and a plate 1 74 is fixedly mounted inside the upper cover 7, a plate 2 75 is mounted on the side of the plate 1 74 facing the feed port 73, and gap sensors 78 are arranged on both sides of the plate 2 75, and two sets of metal pretreatment mechanisms are arranged on the upper cover 7 and the plate 1 74, which are used to soften the parts to be sheared of the metal parts and eliminate static electricity on the metal parts, and the two sets of metal pretreatment mechanisms are respectively located on both sides of the plate 2 75, and the metal pretreatment mechanisms include a parallel clamping jaw cylinder 76 and an argon gas spraying group Parts, a parallel clamping cylinder 76 is fixedly installed on one side of the plate 74 facing the feed port 73, and electrodes 77 are installed on the two groups of clamping jaws on the parallel clamping cylinder 76, and the positions of the two groups of electrodes 77 correspond to the positions of the feed port 73. An argon spraying assembly is arranged on the upper cover 7 for conveying argon toward the inside of the upper cover 7. The argon spraying assembly comprises a nozzle 71 and an argon concentration sensor 72. The nozzle 71 and the argon concentration sensor 72 are both fixedly installed on the top wall of the upper cover 7. A connecting pipe is installed on the top of the nozzle 71, and the nozzle 71 is connected to an external argon conveying device through the connecting pipe. An electric wire is installed on the top of the argon concentration sensor 72, and the argon concentration sensor 72 is connected to an external data processing device through the electric wire.

[0040] When shearing, first, argon is continuously sprayed into the upper cover 7 through the nozzle 71 until the argon concentration sensor 72 detects that the argon concentration in the upper cover 7 reaches the set value. The argon concentration sensor 72 will determine that the upper cover 7 is full of argon and send a feedback signal. Then, the nozzle 71 stops spraying argon, and the external robot will be powered on and work. The robot will grab the metal piece to be sheared and send it into the upper cover 7 from the feed port 73 (at this time, both groups of feed ports 73 are in use). After the metal piece enters from the feed port 73, the metal piece to be sheared is The cut part is sent between the two groups of electrodes 77, and then the parallel clamping cylinder 76 closes the clamping jaws to bring the two groups of electrodes 77 closer together. When the electrodes 77 are brought closer together, the high-frequency power supply is turned on, thereby generating a high-frequency electric field between the two groups of electrodes 77. At this time, the metal parts between the two groups of electrodes 77 will be broken down by the high-frequency electric field and generate high temperature. In this process, the broken-down parts of the metal parts will soften. At the same time, the argon gas between the two groups of electrodes 77 generates plasma at a certain generation rate under the action of the high-frequency electric field, and the metal parts can eliminate static electricity through contact with the plasma.

[0041] Reference Figures 1 to 11The top of the base 1 passes through the outer wall of the lower cover 6 and is fixedly connected with a profile 11. Two groups of brackets 81 are installed on the top of the profile 11, and a shearing mechanism 8 is arranged on the two groups of brackets 81 for shearing the softened parts of the metal parts. The two groups of shearing mechanisms 8 are located between the two groups of metal pretreatment mechanisms, and the positions of the two groups of shearing mechanisms 8 correspond to the positions of the two groups of metal pretreatment mechanisms. The two groups of shearing mechanisms 8 are slightly inclined toward the direction of the plate 2 75. The shearing mechanism 8 includes a swinging jaw cylinder 82, and the two groups of jaws on the swinging jaw cylinder 82 are both equipped with a cutter part 83. The two groups of cutter parts 83 are composed of a knife rod 831 and a knife head 832. The knife head 832 is arranged on the knife rod 831. The knife rod 831 in the two groups of cutter parts 83 is provided with a cutter replacement assembly for replacing the knife head 832 on the knife rod 831. The two groups of cutter replacement assemblies are symmetrical to each other, and one group of cutter replacement assemblies is located above the other group of cutter replacement assemblies, and is located below The square cutter replacement assembly includes a cavity, which is opened on one side of the knife rod 831, and a baffle is detachably installed at the opening of the cavity. A mounting cavity is penetrated at the top of the knife rod 831, and a wire hole 836 is penetrated on the bottom wall of the mounting cavity. The wire hole 836 is used to enable the internal circuit of the mounting cavity to be connected with relevant devices in the outside world. The cavity is connected to the mounting cavity, and multiple groups of knife heads 832 are placed inside the cavity. The size of the knife head 832 corresponds to the size of the opening at the top of the mounting cavity. A groove is opened at the inward end of the mounting cavity, and a through opening is penetrated at the outward end of the mounting cavity. Limiting shoulders 8321 are installed at both ends of the knife head 832, and the two groups of limiting shoulders 8321 are respectively located in the groove and the through opening, and the size of the through opening corresponds to the size of the knife head 832. A force-applying component is provided on the knife rod 831 for applying a thrust to the knife head 832 in the cavity, and an upward push component is provided in the mounting cavity for applying a thrust to the opening of the mounting cavity. The force-applying component and the upward push component are respectively located on both sides of the cavity.

[0042] Afterwards, the softened part of the metal piece is sent between the two groups of cutter parts 83, and the swinging clamping claw cylinder 82 drives the two groups of cutter parts 83 to close and shear the metal piece. By softening the part of the metal piece to be sheared, the difficulty of shearing the metal piece can be reduced, and the service life of the cutter head 832 can be effectively improved, thereby reducing the maintenance times and maintenance costs of the cutter head 832. Softening the part of the metal piece to be sheared can avoid burrs on the metal piece after shearing, thereby effectively improving the shearing quality of the metal piece. In addition, eliminating static electricity on the metal piece can avoid the powder generated when shearing the metal piece from adhering to its surface, thereby improving the quality of subsequent processing procedures such as painting. The two groups of shearing mechanisms 8 are slightly inclined toward the direction of the second plate 75. On the one hand, the scraps of the metal piece sheared can slide smoothly, and on the other hand, they can provide a working space for the electrode 77, so that the part of the metal piece to be sheared can pass through the electrode 77 smoothly and be sheared by the shearing mechanism 8. During operation, the nozzle 71 can continuously replenish argon gas into the upper cover 7 according to the real-time feedback of the argon concentration sensor 72, thereby effectively ensuring the concentration of argon gas in the upper cover 7.

[0043] Reference Figures 6 to 11 The force-applying component includes a U-shaped pull rod 833, both ends of the U-shaped pull rod 833 pass through the outer wall of the knife rod 831 and are slidably connected to the knife rod 831, and push blocks are installed at both ends of the U-shaped pull rod 833, the push block is located in the cavity, and the side of the push block away from the U-shaped pull rod 833 is in contact with a set of side walls of the knife head 832, and two groups of springs 834 are installed on the side of the push block facing the U-shaped pull rod 833, one end of the two groups of springs 834 away from the push block is fixedly connected to the inner wall of the cavity, and the two groups of springs 834 are respectively sleeved on both ends of the U-shaped pull rod 833, and the upward pushing component includes two groups of double-rod cylinders 835, the two groups of double-rod cylinders 835 are symmetrically installed on the bottom wall of the installation cavity, and the output ends of the two groups of double-rod cylinders 835 are commonly connected to the lifting plate 83 7. Two groups of contacts 838 are fixedly installed through the lifting plate 837, and two groups of disc springs 839 are installed on the top of the lifting plate 837. The two groups of disc springs 839 are respectively located directly above the two groups of contacts 838. A limit plate is installed on the side of the lifting plate 837 facing the cavity. A pushing component is arranged in the knife rod 831. The pushing component is located on one side of the groove, and the position of the pushing component corresponds to the position of the groove, and is used to apply thrust toward the direction of the opening. The pushing component includes a multi-section cylinder 8310. The multi-section cylinder 8310 is fixedly installed inside the knife rod 831, and the output end of the multi-section cylinder 8310 passes through the inner wall of the knife rod 831 and is fixedly connected with a push plate 8311. A placement groove is opened on the inner wall of the groove, and the push plate 8311 is located in the placement groove.

[0044] Before the shearing work begins, the baffle at the cavity opening is first removed, and the U-shaped pull rod 833 is pulled to install multiple sets of cutter heads 832 into the cavity (that is, into the cutter rod 831), and then the U-shaped pull rod 833 is released and the baffle is reinstalled. The baffle is set to prevent the cutter heads 832 in the cavity from falling and to prevent the external environment from affecting the cutter heads 832 in the cavity. When the U-shaped pull rod 833 is released, under the rebound force of the spring 834, the push block on the U-shaped pull rod 833 pushes the multiple sets of cutter heads 832 toward the installation cavity. Under the thrust, a set of cutter heads 832 close to the installation cavity are pushed into the installation cavity and fall on the disc spring 839 on the lifting plate 837. Then, the lifting plate 837 and the cutter head 832 on the lifting plate 837 are moved up by the double-rod cylinder 835 until the top ends of the two sets of limit shoulders 8321 on the cutter head 832 are separated. The cutter head 832 is fixed under the limit of the limit shoulder 8321 and the elastic force of the disc spring 839. At this time, the cutting edge of the cutter head 832 has passed through the opening on the installation cavity, so that the subsequent shearing work can be completed. The gap sensor 78 installed on the plate 75 can monitor the gap amount when the two groups of cutter heads 832 are combined in real time, and calculate the wear of the cutter head 832 by feeding back the gap amount to the control assembly. When it is determined that the wear of the cutter head 832 exceeds the requirement, the double-rod cylinder 835 is reset. At this time, the cutter head 832 located in the installation cavity will drop. After the double-rod cylinder 835 is reset, the push plate 8311 applies a thrust to the cutter head 832 in the installation cavity through the multi-section cylinder 8310 until the worn cutter head 832 (that is, the above-mentioned cutter head 832) is pushed out of the installation cavity through the through hole (that is, the cutter rod 831 is pushed out).

[0045] Afterwards, the next set of cutter heads 832 are pushed onto the disc spring 839 under the action of the spring 834, and the double-rod cylinder 835 restarts and lifts the cutter head 832 to its working position and prepares for the next shearing work, thereby realizing the automatic replacement of the cutter head 832. This mechanism of automatic replacement of the cutter head 832 not only saves costs, but also greatly reduces the workload of maintenance personnel. At the same time, through the real-time monitoring and feedback of the wear of the cutter head 832 by the gap sensor 78, it can ensure that the cutter head 832 is in the best working condition each time it is used, thereby effectively preventing the cutter head 832 from affecting its shearing quality due to wear, avoiding burrs, curling, cracks and other defects in the metal parts being sheared, thereby effectively ensuring the quality and stability of the shearing work.

[0046] Reference Figure 1 to Figure 2 as well as Figure 12 to Figure 13The bottom of the feeding pipe 5 is provided with a material distribution and collection mechanism for distributing and collecting the materials dropped from the feeding pipe 5. The material distribution mechanism includes a material distribution pipe 4, which is fixedly installed at the bottom of the feeding pipe 5, and the bottom opening of the material distribution pipe 4 is respectively sealed and fixedly connected with a discharge pipe 1 41 and a discharge pipe 2 42, and a collection box 1 2 and a collection box 2 3 are respectively arranged below the discharge pipe 1 41 and the discharge pipe 2 42. A sorting component is installed on the material distribution pipe 4 for making the materials distributed. The material in the material pipe 4 falls into the discharge pipe 1 41 or the discharge pipe 2 42. The sorting component includes a rotating cylinder 43, which is installed on the outer wall of the distribution pipe 4, and the output end of the rotating cylinder 43 passes through the outer wall of the distribution pipe 4 and is fixedly connected with a rotating rod. One end of the rotating rod is located in the distribution pipe 4 and is rotatably connected to the inner wall of the distribution pipe 4, and a flap 44 is installed on the outer wall of the rotating rod. The four groups of side walls on the flap 44 are respectively in contact with the four groups of side walls in the distribution pipe 4.

[0047] The scraps cut off by the cutting knife part 83 will fall onto the flap 44. At this time, the rotating cylinder 43 drives the flap 44 to flip toward the discharge pipe 41, so that the scraps can fall from the discharge pipe 41 into the collection box 2 for collection. When the worn cutter head 832 is pushed onto the flap 44, the rotating cylinder 43 drives the flap 44 to flip toward the discharge pipe 42, so that the worn cutter head 832 can fall from the discharge pipe 42 into the collection box 23 for collection. In order to maintain the good operation of the shearing equipment, the staff needs to clean the collection box 2 and the collection box 3 regularly. By separating and collecting the scraps and the cutter head 832, not only the smooth operation of the equipment can be ensured, but also the workload of the staff is greatly reduced, thereby improving the work efficiency of the staff.

[0048] When the force applied to the cutter head 832 exceeds the elastic force of the disc spring 839, the disc spring 839 will be pressed down and contact the contact 838. After the contact 838 is triggered, the double-rod cylinder 835 will immediately reset and emergency stop the robot (the cutter head 832 will retract into the installation cavity at this time). At the same time, the robot after the emergency stop will sound an alarm to notify the maintenance personnel to check the equipment, so as to prevent the cutter head 832 from breaking due to overload. On the one hand, preventing the cutter head 832 from breaking can effectively ensure the service life of the cutter head 832. On the other hand, preventing the cutter head 832 from breaking can avoid damage to the surface of the metal part. At this time, the setting of the lower cover 6 and the upper cover 7 can protect the safety of on-site personnel, that is, prevent the fragments of the cutter head 832 from flying out and injuring on-site personnel.

[0049] The present invention is applied to the shearing of automobile interior metal parts in an automated workshop. The base 1 is fixed to the ground by bolts thereon, the lower cover 6 and the feed pipe 5 are welded and fixedly connected to the base 1, the upper cover 7 is fixedly connected to the top of the lower cover 6, the feed pipe 4 is fixedly connected to the bottom of the feed pipe 5, and two sets of shearing mechanisms 8 are installed on the profile 11 through a bracket 81, so as to meet the shearing work of two production lines in one workstation. When the shearing work is performed, argon gas is firstly continuously sprayed into the upper cover 7 through the nozzle 71 until the argon concentration sensor 72 detects that the argon concentration in the upper cover 7 reaches a set value. The argon concentration sensor 72 will determine that the upper cover 7 is full of argon gas and send a feedback signal. After that, the nozzle 71 stops spraying argon gas, and the external robot will be powered on to work. The robot grabs the metal parts to be sheared and takes them from the feeder. The metal parts are fed into the upper cover 7 through the feed port 73 (at this time, both groups of feed ports 73 are in use), a parallel clamping cylinder 76 is installed on the plate 1 74, and an electrode 77 is installed on the clamping jaws of the parallel clamping cylinder 76. After the metal parts enter from the feed port 73, the part to be sheared of the metal parts is fed between the two groups of electrodes 77, and then the parallel clamping cylinder 76 closes the clamping jaws to bring the two groups of electrodes 77 closer together. When the electrodes 77 are brought closer together, a high-frequency power supply is turned on, thereby generating a high-frequency electric field between the two groups of electrodes 77. At this time, the part of the metal part between the two groups of electrodes 77 will be broken down by the high-frequency electric field and generate high temperature. In this process, the part of the metal part that is broken down will soften. At the same time, the argon gas between the two groups of electrodes 77 generates plasma at a certain generation rate under the action of the high-frequency electric field, and the metal parts can eliminate static electricity thereon by contacting with the plasma.

[0050] Afterwards, the softened part of the metal piece is sent between the two sets of cutting knife parts 83, and the swinging clamping claw cylinder 82 drives the two sets of cutting knife parts 83 to close and shear the metal piece. The sheared scraps fall onto the flap 44, and at this time, the rotating cylinder 43 drives the flap 44 to flip toward the discharge pipe 41, so that the scraps can fall from the discharge pipe 41 into the collecting box 2 for collection. By softening the part of the metal piece to be sheared, the difficulty of shearing the metal piece can be reduced, and the service life of the cutter head 832 can be effectively improved, thereby reducing the maintenance frequency and maintenance cost of the cutter head 832. In addition, softening the part of the metal piece to be sheared can avoid burrs on the metal piece after shearing. Thereby, the shearing quality of metal parts is effectively improved. In addition, eliminating static electricity on metal parts can prevent powder generated when shearing metal parts from adhering to their surfaces, thereby improving the quality of subsequent processing steps such as painting. The two sets of shearing mechanisms 8 are slightly inclined toward the direction of plate 2 75. On the one hand, they can allow the scraps of metal parts sheared off to slide smoothly, and on the other hand, they can provide a working space for the electrode 77, so that the part of the metal part to be sheared can pass through the electrode 77 smoothly and be sheared by the shearing mechanism 8. During operation, the nozzle 71 can continuously replenish argon into the upper cover 7 according to the real-time feedback of the argon concentration sensor 72, thereby effectively ensuring the concentration of argon in the upper cover 7.

[0051] Before the shearing work begins, the baffle at the cavity opening is first removed, and the U-shaped pull rod 833 is pulled to install multiple sets of cutter heads 832 into the cavity (that is, into the cutter rod 831), and then the U-shaped pull rod 833 is released and the baffle is reinstalled. The baffle is set to prevent the cutter heads 832 in the cavity from falling and to prevent the external environment from affecting the cutter heads 832 in the cavity. When the U-shaped pull rod 833 is released, under the rebound force of the spring 834, the push block on the U-shaped pull rod 833 pushes the multiple sets of cutter heads 832 toward the installation cavity. Under the thrust, a set of cutter heads 832 close to the installation cavity are pushed into the installation cavity and fall on the disc spring 839 on the lifting plate 837. Then, the lifting plate 837 and the cutter head 832 on the lifting plate 837 are moved up by the double-rod cylinder 835 until the top ends of the two sets of limit shoulders 8321 on the cutter head 832 are separated. The cutter head 832 is fixed under the limit of the limit shoulder 8321 and the elastic force of the disc spring 839. At this time, the cutting edge of the cutter head 832 has passed through the opening on the installation cavity, so that the subsequent shearing work can be completed. The gap sensor 78 installed on the plate 75 can monitor the gap amount when the two groups of cutter heads 832 are combined in real time, and calculate the wear of the cutter head 832 by feeding back the gap amount to the control assembly. When it is determined that the wear of the cutter head 832 exceeds the requirement, the double-rod cylinder 835 is reset. At this time, the cutter head 832 located in the installation cavity will drop. After the double-rod cylinder 835 is reset, the push plate 8311 applies a thrust to the cutter head 832 in the installation cavity through the multi-section cylinder 8310 until the worn cutter head 832 (that is, the above-mentioned cutter head 832) is pushed out of the installation cavity through the through hole (that is, the cutter rod 831 is pushed out).

[0052] Afterwards, the next set of cutter heads 832 are pushed onto the disc spring 839 under the action of the spring 834, the double-rod cylinder 835 restarts, and lifts the cutter head 832 to its working position, and prepares for the next shearing work, thereby realizing the automatic replacement of the cutter head 832. This mechanism of automatic replacement of the cutter head 832 not only saves costs, but also greatly reduces the workload of maintenance personnel. At the same time, the real-time monitoring and feedback of the wear of the cutter head 832 by the gap sensor 78 can ensure that the cutter head 832 is in the best working condition each time it is used, thereby effectively preventing the cutter head 832 from affecting its shearing quality due to wear, avoiding burrs, curling, cracks and other defects on the sheared metal parts, and thus effectively ensuring the quality and stability of the shearing work.

[0053] The worn cutter head 832 that is pushed down will fall onto the flap 44. At this time, the rotating cylinder 43 drives the flap 44 to flip toward the discharge pipe 42, so that the worn cutter head 832 can fall from the discharge pipe 42 into the collection box 2 3 for collection. In order to maintain the good operation of the shearing equipment, the staff needs to clean the collection box 1 2 and the collection box 2 3 regularly. By separating and collecting the scraps and the cutter head 832, not only the smooth operation of the equipment can be ensured, but also the workload of the staff can be greatly reduced, thereby improving the work efficiency of the staff.

[0054] When the force applied to the cutter head 832 exceeds the elastic force of the disc spring 839, the disc spring 839 will be pressed down and contact the contact 838. After the contact 838 is triggered, the double-rod cylinder 835 will immediately reset and emergency stop the robot (the cutter head 832 will retract into the installation cavity at this time). At the same time, the robot after the emergency stop will sound an alarm to notify the maintenance personnel to check the equipment, so as to prevent the cutter head 832 from breaking due to overload. On the one hand, preventing the cutter head 832 from breaking can effectively ensure the service life of the cutter head 832. On the other hand, preventing the cutter head 832 from breaking can avoid damage to the surface of the metal part. At this time, the setting of the lower cover 6 and the upper cover 7 can protect the safety of on-site personnel, that is, prevent the fragments of the cutter head 832 from flying out and injuring on-site personnel.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
