Technical Field

[0001] The invention relates to the technical field of welding, in particular to a welding machine for carburizing gear processing. Background Art

[0002] Gears usually refer to mechanical elements with teeth on the wheel rim that can continuously mesh to transmit motion and power. They can realize mechanical propulsion and power transmission, and have become common basic units and components in mechanical structures. Gears have the advantages of stable structure and a wide range of functional uses.

[0003] The patent with patent announcement number CN219787184U discloses a welding machine for carburizing gear processing, which relates to the technical field of carburizing gear processing, including a base plate and a carburizing gear rotating assembly; base plate: a welding assembly is installed on the right side; carburizing gear rotating assembly: includes a fixed plate, a first motor, a rotating shaft, a brush slip ring, a mounting frame, a first electric telescopic rod and a fixed frame, a fixed plate is fixed to the rear end of the upper side of the base plate, a first motor is installed on the rear side of the fixed plate, a rotating shaft is fixed on the output shaft of the first motor, a brush slip ring is installed on the circumferential surface of the rotating shaft, a mounting frame is fixed to the front end of the rotating shaft, two corresponding first electric telescopic rods are installed on the rear side of the mounting frame, and a fixed frame is fixed on the telescopic arm of the first electric telescopic rod, which can perform rotation welding on the carburized gear and avoid the carburized gear from being offset during welding.

[0004] However, the device still has some shortcomings: the device can perform stable and rotational welding on carburized gears, but before the welding work begins, the staff needs to manually clean the debris attached to the surface of the gear.

A T-shaped plate is fixedly installed at the edge, and the carburized gear is placed inside the fixed ring. The micro motor inside the rotating column is started, and the output end of the micro motor drives the receiving plate to rotate. When the receiving plate rotates, it drives the fixed ring to rotate. When the fixed ring rotates, it drives the through column to rotate. When the through column rotates, it drives the semi-arc plate to rotate. When the semi-arc plate revolves, it contacts the arc surface of the resistance block to generate resistance force, and the circular plate limits the resistance block. The through column moves toward the center of the fixed ring through the guidance and limitation of the arc surface of the semi-arc plate, and the through column is deformed after being subjected to the resistance force through the spring between it and the inside of the fixed ring. Subsequently, the through column drives the sliding column to move synchronously, and the sliding column drives the T-shaped clamping plate to move synchronously. The T-shaped clamping plate penetrates into the tooth gap of the gear to stably clamp and limit the gear. , through the setting of the sliding column and the internal spring of the through column, the T-shaped clamping plate can always be close to the inner wall of the gear, and the L-shaped sliding assembly is adjusted by the slide rail to adjust the welding position, and the welding gun assembly is started to weld the carburized gear. When the gear welding position needs to be rotated, the fixed ring remains stationary, and the motor is started. The output end of the motor drives the circular plate to rotate, and the circular plate drives the rotating column, the receiving plate and the fixed ring to rotate, thereby realizing the rotation welding of the gear; when the semi-arc plate revolves, the arc surface of the outer wall will contact the arc surface of the outer wall of the T-shaped plate to generate a resistance force, and the arc surface guidance of the semi-arc plate prompts the T-shaped plate to push the vertical plate to slide backward along the top of the device body, and the vertical plate drives the cold air assembly to move, and the cold air assembly blows away the dirt attached to the outer wall of the gear.

[0007] According to the above technical solution, the right end of the semi-arc plate is slidingly connected to the left side of the circular plate, the arc surface of the outer wall of the resistance block is located on the movement trajectory of the semi-arc plate, the T-shaped plate is located on the right side of the cold air component, and the arc surface of the outer wall of the T-shaped plate is located on the movement trajectory of the semi-arc plate. A circulation device is provided on the front side of the vertical plate to ensure uniform mixing of cold and hot gases in the welding area.

[0008] According to the above technical scheme, the circulation device includes a stabilizing plate, a reset plate, a rotating rod and several hollow plates. The bottom of the stabilizing plate is fixedly installed at the top edge of the device body, the stabilizing plate is located on the back of the vertical plate, the reset plate is fixedly installed between the front of the stabilizing plate and the back of the vertical plate, the left end of the rotating rod is rotatably installed on the front of the stabilizing plate, and several hollow plates are equidistant and fixedly installed on the outer wall of the rotating rod. When the fixed ring drives the gear to perform rotational welding, the vertical plate will slide backward along the non-self-locking spiral groove on the outer wall of the rotating rod, and the built-in clamping block of the vertical plate continuously resists the inner wall of the spiral groove of the rotating rod, causing the rotating rod to generate a rotational force and start to rotate. At this time, the stabilizing plate limits the rotating rod, and the vertical plate resists the reset plate to deform. After that, the reset plate pushes the vertical plate to reset synchronously through its own elastic reset, and this reciprocating process causes the rotating rod to rotate and drive the hollow plate to rotate.

[0009] According to the above technical solution, a spiral groove is provided on the outer wall of the left end of the rotating rod, the interior of the vertical plate is in contact with the outer wall of the spiral groove of the rotating rod, an arc groove is provided on the outer wall of the rotating rod, a U-shaped groove is provided on the interior of the hollow plate close to the side of the vertical plate, and an identification device is provided on the outer wall of the hollow plate for judging whether the metal composition of the gear is normal by knocking on the carburized gear and then hearing the knocking sound.

[0010] According to the above technical solution, the circulation device also includes a vertical rod, a push ring, an elastic telescopic rod and a plurality of moisture-proof plates. The top of the vertical rod is slidably installed in the arc-shaped groove of the rotating rod. The bottom of the inner wall of the push ring is fixedly installed on the top of the vertical rod. The bottom of the push ring is slidably connected to the top of the device body. The elastic telescopic rod consists of a fixed end and a telescopic end. The front side of the fixed end of the elastic telescopic rod is fixedly installed in the hollow plate, and a groove is provided on the outer wall of the telescopic end of the elastic telescopic rod. The moisture-proof plates are hinged at the inner wall of the hollow plate away from the outer wall of the rotating rod. The arc surface of the moisture-proof plate close to the outer wall of the rotating rod is located at the elastic On the motion trajectory of the groove at the telescopic end of the elastic telescopic rod, the arc groove restricts the vertical rod when the rotating rod rotates, so that the vertical rod can drive the push ring to slide synchronously along the top of the device body when it slides back and forth inside the arc groove of the rotating rod. At the same time, when the push ring slides forward, it will resist the telescopic end of the elastic telescopic rod from contracting toward its fixed end. When the telescopic end of the elastic telescopic rod contracts, the moisture-proof board is pulled through the groove on the outer wall. The moisture-proof board causes its own hinge axis to start rotating through the pulling force. At this time, the hinge axis of the moisture-proof board is the axis center and swings and deviates in an arc shape along the inner wall of the U-shaped groove of the hollow plate. When the telescopic end of the elastic telescopic rod is reset, the moisture-proof board is reset synchronously, and this process repeats.

[0011] According to the above technical solution, the identification device includes a reciprocating screw, a limit plate, an elastic telescopic plate, a cross plate and a transmission plate. The back of the reciprocating screw is fixedly installed on the front of the rotating rod. The limit plate passes through and is slidably installed on the outer wall surface of the reciprocating screw. The elastic telescopic plate is composed of a fixed end and a telescopic end. The outer wall of the fixed end of the elastic telescopic plate is fixedly installed on the outer wall of the hollow plate. The back of the cross plate is fixedly installed on the front of the elastic telescopic plate. The transmission plate is fixedly installed on the outer wall of the cross plate away from the outer wall of the rotating rod. When the rotating rod rotates, the reciprocating screw is driven to rotate. When rotating, the reciprocating spiral groove on its outer wall limits the internal block of the limit plate, so that the limit plate can slide back and forth along the top of the device body when the reciprocating screw rotates. At the same time, the hollow plate drives the elastic telescopic plate to move synchronously, the elastic telescopic plate drives the cross plate to revolve, and the cross plate drives the transmission plate to move synchronously. When the cross plate rotates to above the rotating rod, the limit plate contacts the arc surface of the transmission plate to generate an upward thrust, the transmission plate pushes the cross plate to move synchronously, the cross plate pulls the telescopic end of the elastic telescopic plate to move upward, and the top of the telescopic end of the elastic telescopic plate hits the exposed part of the gear on the outside of the fixed ring to generate vibration.

[0012] According to the above technical solution, the bottom of the limit plate is slidably connected to the top of the device body, the telescopic end of the elastic telescopic plate is hollow, and the arc surface of the transmission plate is located on the movement trajectory of the limit plate.

[0013] According to the above technical scheme, the identification device also includes an arc-shaped spring plate, a scraper and a positioning plate. The outer wall of the arc-shaped spring plate is fixedly installed on the outer wall of the telescopic end of the elastic telescopic plate, and the scraper is slidably installed on the outer wall of the fixed end of the elastic telescopic plate close to the outer wall of the rotating rod. The outer wall of the scraper contacts the inner wall of the bottom of the arc-shaped spring plate, and the positioning plate is fixedly installed above the outer wall of the fixed end of the elastic telescopic plate close to the outer wall of the rotating rod. The positioning plate is located on the movement trajectory of the scraper. When the telescopic end of the elastic telescopic plate contracts, the arc-shaped spring plate is driven to move synchronously, and the arc-shaped spring plate drives the scraper to slide synchronously along the outer wall of the fixed end of the elastic telescopic plate. When the scraper is limited by the positioning plate, the arc-shaped spring plate is stretched and deformed by its own elasticity.

[0014] The present invention provides a welding machine for carburizing gear processing, which has the following beneficial effects:

[0015] (1) The present invention achieves stable clamping of gears of different diameters during welding by cooperating with a rotating column, a receiving plate, a fixing ring, a through column, a sliding column, a T-shaped clamping plate, a semi-arc plate, an abutment block, a vertical plate, a cold air assembly and a T-shaped plate to avoid welding accidents and prevent the gears from being deviated due to external interference during welding, thereby reducing the welding accuracy. At the same time, the rotation welding of the gears is achieved while ensuring the welding accuracy, thereby avoiding the need for workers to frequently adjust the welding position and delay the welding progress. At the same time, the cold air assembly is prompted to expand its own cold air dissipation range while slowly cooling the welding area to prevent the gears from generating strong stress and cracks in the high temperature of welding, and to prevent dirt from being directly welded to the weld by the welding gun assembly, thereby causing slag inclusions and pores in the gear weld to reduce the welding strength.

[0016] (2) The present invention, through the arrangement of a circulation device, cooperates with a vertical plate, a stabilizing plate, a reset plate, a rotating rod, a hollow plate, a vertical rod, a push ring, an elastic telescopic rod and a moisture-proof plate, and relies on the rotation of the hollow plate to further accelerate the circulation speed of the cold and hot gases in the welding area on the original basis, thereby reducing the temperature difference in different welding areas to avoid adverse effects on the slow lowering of the gears, and at the same time avoiding the cold and hot gases from converging and breeding water vapor due to excessive temperature differences, which affects the welding quality; and when the hollow plate rotates to achieve turbulence, the moisture-proof plate increases the disturbance and diffusion direction of the cold and hot air flows by the continuous swing of the hollow plate, and at the same time, the moisture in the welding area is effectively absorbed during the continuous swing of the moisture-proof plate, thereby avoiding water vapor erosion of the welding gun assembly and increasing the probability of damage to the welding gun assembly.

[0017] (3) The present invention sets up an identification device, and cooperates with a rotating rod, a reciprocating screw rod, a limit plate, an elastic expansion plate, a cross plate, a transmission plate, an arc spring plate, a scraper and a positioning plate. The revolution of the elastic expansion plate is used to achieve indirect impact vibration on the gear to avoid loosening of the gear clamping caused by frequent impact. The crisp sound emitted by the impact of the elastic expansion plate is convenient for the staff to judge whether the metal composition of the gear is normal during the welding process to check the welding quality. The vibration force is used to reduce the adhesion strength of tiny sticky dirt on the surface of the gear, thereby improving the removal effect of the dirt by the cold air component; and the sparks attached to the outer wall of the fixed end of the elastic expansion plate are scraped off to reduce the attachment time of the sparks and thus reduce the degree of scalding of the elastic expansion plate. The arc spring plate continuously changes the arc amplitude of the outer wall to guide the dirt blown off by the cold air component to the inside of the hollow plate. When the hollow plate rotates to the bottom of the rotating rod, the dirt falls into the collection tank of the device body. BRIEF DESCRIPTION OF THE DRAWINGS

A receiving plate 7 is fixedly installed at the left end of the rotating column 6. The right side of the receiving plate 7 is fixedly connected to the left side of the output end of the micro motor inside the rotating column 6. A fixing ring 8 is fixedly installed on the left side of the receiving plate 7. A plurality of ventilation holes are opened on the outer wall of the fixing ring 8. A penetrating column 9 is slidably installed inside the fixing ring 8 through a spring. A sliding column 10 is slidably installed inside the penetrating column 9 near the center of the fixing ring 8. The sliding column 10 is fixed near the center of the fixing ring 8. A T-shaped card plate 11 is fixedly installed, a semi-arc plate 12 is fixedly installed at one end of the outer wall of the penetrating column 9 away from the fixing ring 8, a plurality of abutment blocks 13 are fixedly installed on the left outer wall of the circular plate 32, and the plurality of abutment blocks 13 are equidistantly distributed on the left outer wall of the circular plate 32, a vertical plate 14 is slidably installed at the top edge of the device body 1, a cold air assembly 15 is fixedly installed on the front of the vertical plate 14, and a T-shaped plate 16 is fixedly installed on the front edge of the vertical plate 14. Through the above cooperation, stable clamping of gears of different sizes and diameters during welding is achieved to avoid welding accidents, to avoid gears being disturbed by external forces and offset during welding, resulting in reduced welding accuracy, and to achieve rotational welding of gears while ensuring welding accuracy, so as to avoid the need for staff to frequently adjust the welding position and delay welding progress; through the above cooperation, the cold air assembly 15 is prompted to expand its own cold air dissipation range, while slowly cooling the welding area to prevent the gears from generating strong stress and cracks in the high temperature of welding, and to prevent dirt from being directly welded to the weld by the welding gun assembly 22, resulting in slag inclusions and pores at the gear weld to reduce welding strength.

[0030] The right end of the semi-arc plate 12 is slidably connected to the left side of the circular plate 32. The arc surface of the outer wall of the abutment block 13 is located on the movement trajectory of the semi-arc plate 12. The T-shaped plate 16 is located on the right side of the cold air component 15. The arc surface of the outer wall of the T-shaped plate 16 is located on the movement trajectory of the semi-arc plate 12. A circulation device 4 is provided on the front of the vertical plate 14 to ensure uniform mixing of cold and hot gases in the welding area.

[0031] When in use, the carburized gear is placed inside the fixed ring 8, and the micro-motor inside the rotating column 6 is started. The output end of the micro-motor drives the receiving plate 7 to rotate, and the receiving plate 7 drives the fixed ring 8 to rotate when it rotates. When the fixed ring 8 rotates, it drives the through-column 9 to rotate, and when the through-column 9 rotates, it drives the semi-arc plate 12 to rotate. When the semi-arc plate 12 revolves, it contacts the arc surface of the resistance block 13 to generate resistance force, and the circular plate 32 limits the resistance block 13. The through-column 9 moves toward the center direction of the fixed ring 8 through the guidance and limitation of the arc surface of the semi-arc plate 12, and the through-column 9 passes through the space between the semi-arc plate 12 and the inside of the fixed ring 8. The spring is deformed after being subjected to the resistance force, and then the through column 9 drives the sliding column 10 to move synchronously, and the sliding column 10 drives the T-shaped clamping plate 11 to move synchronously, and the T-shaped clamping plate 11 penetrates into the tooth gap of the gear to stably clamp and limit the gear. The setting of the internal spring of the sliding column 10 and the through column 9 enables the T-shaped clamping plate 11 to always be close to the inner wall of the gear. At the same time, the L-shaped sliding assembly 21 is adjusted for welding position by the slide rail 2, and the welding gun assembly 22 is started to weld the carburized gear. When the gear welding position needs to be rotated, the fixed ring 8 remains stationary, and the motor 31 is started. The output end of the motor 31 drives the circular plate 32 to rotate, and the circular plate 32 drives the rotating column 6, the receiving plate 7 and the fixing ring 8 to rotate, thereby realizing the rotation welding of the gear. Through the above cooperation, stable clamping of gears of different sizes and diameters during the welding process is realized to avoid welding accidents, and to avoid the gears being disturbed by external forces during the welding process and deviating, resulting in reduced welding accuracy. At the same time, the rotation welding of the gears is realized under the premise of ensuring the welding accuracy, avoiding the need for the staff to frequently adjust the welding position and delay the welding progress; when the semi-arc plate 12 revolves, the outer wall arc surface will contact the outer wall arc surface of the T-shaped plate 16 A resistance force is generated, and the arc surface guidance of the semi-arc plate 12 causes the T-shaped plate 16 to push the vertical plate 14 to slide backward along the top of the device body 1. The vertical plate 14 drives the cold air component 15 to move, and the cold air component 15 blows away the dirt attached to the outer wall of the gear. Through the above cooperation, the cold air component 15 expands its own cold air emission range, and slowly cools down the welding area to prevent the gear from generating strong stress and cracks in the high temperature of welding, and prevents dirt from being directly welded to the weld by the welding gun component 22, resulting in slag inclusions and pores in the gear weld, reducing the welding strength.

[0032] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a circulation device 4;

[0033] The circulation device 4 includes a stabilizing plate 41, a reset plate 42, a rotating rod 43 and a plurality of hollow plates 44. The bottom of the stabilizing plate 41 is fixedly installed at the top edge of the device body 1, the stabilizing plate 41 is located on the back of the vertical plate 14, the reset plate 42 is fixedly installed between the front of the stabilizing plate 41 and the back of the vertical plate 14, the left end of the rotating rod 43 is rotatably installed on the front of the stabilizing plate 41, and a plurality of hollow plates 44 are equidistant and fixedly installed on the outer wall of the rotating rod 43. Through the above coordination, the rotation of the hollow plate 44 can further accelerate the circulation speed of the cold and hot gases in the welding area on the original basis, reduce the temperature difference in different welding areas to avoid adverse effects on the slow lowering of the gear, and at the same time avoid the cold and hot gases from gathering and breeding water vapor due to excessive temperature difference, affecting the welding quality.

[0034] A spiral groove is provided on the outer wall of the left end of the rotating rod 43, the interior of the vertical plate 14 contacts the outer wall of the spiral groove of the rotating rod 43, an arc groove is provided on the outer wall of the rotating rod 43, a U-shaped groove is provided on the inner side of the hollow plate 44 close to the vertical plate 14, and an identification device 5 is provided on the outer wall of the hollow plate 44 for judging whether the metal composition of the gear is normal by the knocking sound after knocking the carburized gear.

[0035] The circulation device 4 also includes a vertical rod 45, a push ring 46, an elastic telescopic rod 47 and a plurality of moisture-proof plates 48. The top of the vertical rod 45 is slidably mounted inside the arc groove of the rotating rod 43. The bottom of the inner wall of the push ring 46 is fixedly mounted on the top of the vertical rod 45. The bottom of the push ring 46 is slidably connected to the top of the device body 1. The elastic telescopic rod 47 consists of a fixed end and a telescopic end. The front of the fixed end of the elastic telescopic rod 47 is fixedly mounted inside the hollow plate 44, and a groove is provided on the outer wall of the telescopic end of the elastic telescopic rod 47. The plurality of moisture-proof plates 48 are away from One side of the outer wall of the rotating rod 43 is hinged to the inner wall of the hollow plate 44, and the arc surface of the moisture-proof plate 48 close to the outer wall of the rotating rod 43 is located on the movement trajectory of the groove at the telescopic end of the elastic telescopic rod 47. When the hollow plate 44 rotates to disturb the air flow through the above cooperation, the moisture-proof plate 48 increases the disturbance and diffusion direction of the cold and hot air flows by the hollow plate 44 through continuous swinging. At the same time, the moisture-proof plate 48 effectively absorbs the moisture in the welding area during the continuous swinging process, thereby preventing water vapor from eroding the welding gun assembly 22 and increasing the probability of damage to the welding gun assembly 22.

[0036] When in use, when the fixing ring 8 drives the gear to perform rotational welding, the vertical plate 14 will slide backward along the non-self-locking spiral groove on the outer wall of the rotating rod 43, and the built-in block of the vertical plate 14 will continuously resist the inner wall of the spiral groove of the rotating rod 43, causing the rotating rod 43 to generate a rotating force and start to rotate. At this time, the stabilizing plate 41 limits the rotating rod 43, and the vertical plate 14 resists the reset plate 42 to deform, and then the reset plate 42 pushes the vertical plate 14 to reset synchronously through its own elastic reset, and the reciprocating process causes the rotating rod 43 to rotate and drive the hollow plate 44 to rotate. Through the above cooperation, the rotation of the hollow plate 44 further accelerates the circulation speed of the cold and hot gases in the welding area on the original basis, reduces the temperature difference in different welding areas, avoids the adverse effect on the slow lowering of the gear, and avoids the cold and hot gases from gathering and breeding water vapor due to excessive temperature difference, which affects the welding quality; when the rotating rod 43 rotates, the arc groove restricts the vertical rod 45, prompting When the vertical rod 45 slides back and forth inside the arc-shaped groove of the rotating rod 43, it can drive the push ring 46 to slide synchronously along the top of the device body 1. At the same time, when the push ring 46 slides forward, it will resist the telescopic end of the elastic telescopic rod 47 to shrink toward the inside of its fixed end. When the telescopic end of the elastic telescopic rod 47 shrinks, it pulls the moisture-proof plate 48 through the groove on the outer wall. The moisture-proof plate 48 causes its own hinge axis to start rotating through the pulling force. At this time, the hinge axis of the moisture-proof plate 48 is the axis center and swings and deviates in an arc shape along the inner wall of the U-shaped groove of the hollow plate 44. When the telescopic end of the elastic telescopic rod 47 is reset, the moisture-proof plate 48 is reset synchronously, and so on. When the hollow plate 44 rotates to realize the turbulence through the above cooperation, the moisture-proof plate 48 increases the disturbance and diffusion direction of the cold and hot air flows by the hollow plate 44 through continuous swinging. At the same time, the moisture-proof plate 48 effectively absorbs the moisture in the welding area during the continuous swinging process to prevent water vapor from eroding the welding gun assembly 22 and increasing the probability of damage to the welding gun assembly 22.

Through the above cooperation, the revolution of the elastic telescopic plate 53 is relied on to realize indirect impact vibration of the gear to avoid frequent impacts that cause the clamping of the gear to loosen, and the crisp sound emitted by the impact of the elastic telescopic plate 53 is convenient for the staff to judge whether the metal composition of the gear is normal during the welding process to check the welding quality, and the adhesion strength of the tiny sticky dirt on the surface of the gear is reduced by the vibration force, so as to improve the removal effect of the cold air component 15 on the dirt.

[0039] The bottom of the limiting plate 52 is slidably connected to the top of the device body 1 , the telescopic end of the elastic telescopic plate 53 is hollow in design, and the arc surface of the transmission plate 55 is located on the movement track of the limiting plate 52 .

[0040] The identification device 5 also includes an arc-shaped spring plate 56, a scraper plate 57 and a positioning plate 58. The outer wall of the arc-shaped spring plate 56 is fixedly installed on the outer wall of the telescopic end of the elastic telescopic plate 53, and the scraper plate 57 is slidably installed on the outer wall of the fixed end of the elastic telescopic plate 53 near the outer wall of the rotating rod 43. The outer wall of the scraper plate 57 contacts the inner wall at the bottom of the arc-shaped spring plate 56, and the positioning plate 58 is fixedly installed on the upper part of the outer wall of the fixed end of the elastic telescopic plate 53 near the outer wall of the rotating rod 43. The positioning plate 58 is located on the movement trajectory of the scraper plate 57. Through the above cooperation, the sparks attached to the outer wall of the fixed end of the elastic telescopic plate 53 are scraped off, the attachment time of the sparks is reduced, thereby reducing the degree of scalding of the elastic telescopic plate 53, and the arc-shaped spring plate 56 continuously changes the arc amplitude of the outer wall to guide the dirt blown off by the cold air component 15 to the inside of the hollow plate 44. When the hollow plate 44 rotates to the bottom of the rotating rod 43, the dirt falls into the collection groove of the device body 1.

[0041] When in use, the rotation of the rotating rod 43 drives the reciprocating screw rod 51 to rotate. When the reciprocating screw rod 51 rotates, the reciprocating spiral groove on its outer wall limits the internal block of the limit plate 52, so that the limit plate 52 can slide back and forth along the top of the device body 1 when the reciprocating screw rod 51 rotates. At the same time, the hollow plate 44 drives the elastic expansion plate 53 to move synchronously, and the elastic expansion plate 53 drives the cross plate 54 to revolve, and the cross plate 54 drives the transmission plate 55 to move synchronously. When the cross plate 54 rotates to the top of the rotating rod 43, the limit plate 52 resists the arc surface of the transmission plate 55 to generate an upward thrust, and the transmission plate 55 pushes the cross plate 54 to move synchronously, and the cross plate 54 pulls the expansion end of the elastic expansion plate 53 to move upward, and the top of the expansion end of the elastic expansion plate 53 hits the exposed outer part of the gear of the fixing ring 8 to generate vibration. Through the above cooperation, the revolution of the elastic expansion plate 53 is used to achieve indirect impact vibration on the gear to avoid frequent impacts that cause the clamping of the gear to loosen, and the elastic expansion plate The crisp sound emitted when 53 hits is convenient for the staff to judge whether the metal composition of the gear is normal during the welding process to check the welding quality, and the vibration force is used to reduce the adhesion strength of the tiny sticky dirt on the gear surface to improve the removal effect of the cold air component 15 on the dirt; when the telescopic end of the elastic telescopic plate 53 contracts, it drives the arc spring plate 56 to move synchronously, and the arc spring plate 56 drives the scraper 57 to slide synchronously along the outer wall of the fixed end of the elastic telescopic plate 53. When the scraper 57 is limited by the positioning plate 58, the arc spring plate 56 is stretched and deformed by its own elasticity. Through the above cooperation, the sparks attached to the outer wall of the fixed end of the elastic telescopic plate 53 are scraped off, the attachment time of the sparks is reduced, thereby reducing the degree of scalding of the elastic telescopic plate 53, and the arc spring plate 56 continuously changes the arc amplitude of the outer wall to guide the dirt blown off by the cold air component 15 to the inside of the hollow plate 44. When the hollow plate 44 rotates to the bottom of the rotating rod 43, the dirt falls into the collection tank of the device body 1.
