Technical Field

[0001] The present invention relates to the technical field of drilling machines, and particularly relates to a drilling device for machining the base of a pump unit. Background Art

[0002] A drilling machine is a general-purpose machine tool with a wide range of uses, which can be used for machining parts such as drilling, reaming, boring, counterboring, and tapping. When a process equipment is equipped on the drilling machine, boring can also be carried out. In addition, cleaning the iron chips on the drilling machine is a crucial link in machining. If the iron chips remain in precision components such as the guide rails and bearings of the drilling machine, it will accelerate wear and affect the equipment accuracy.

[0003] Chinese Patent with Publication No. CN116037977B discloses an adjustable and quickly positioned bench drill for machining, including a bench drill body, and a bench drill frame is provided on the bench drill body; the bench drill frame includes a fixed frame connected to the bench drill body, and a receiving plate is slidably connected to the fixed frame in the up-down, left-right directions, and a fixing structure is provided on the receiving plate; an adjusting disk is slidably connected to the fixed frame, and a rotating disk is rotatably connected to the adjusting disk; a U-shaped frame is slidably connected to the rotating disk, and an adjusting frame is rotatably connected to the U-shaped frame. The adjusting frame rotates along the U-shaped frame as the rotating disk rotates, and the rotation speed of the adjusting frame is twice that of the rotating disk; a guiding frame is fixedly connected to the receiving plate, and a transverse slider is slidably connected to the guiding frame; an adjusting block is slidably connected to the adjusting frame, and the adjusting block is rotatably connected to the transverse slider.

[0004] In the implementation of the above technical solution, the workpiece is fixed through the fixing structure. When the continuous hole positions are in a linear array, by sliding the guiding frame along the transverse slider, the receiving plate is driven to move horizontally along the transverse slider; by sliding the adjusting disk along the fixed frame, the adjusting disk drives the transverse slider to move vertically through the rotating disk, U-shaped frame, adjusting frame, and adjusting block, and the transverse slider drives the receiving plate to move vertically through the guiding frame, so as to realize the drilling of the workpiece on the fixing structure by the bench drill body for the hole positions with continuous hole positions in a linear array; however, when machining some workpieces, a sub-workbench needs to be installed on the main workbench of the bench drill body. At this time, during the drilling process, a large amount of iron chips will fall on the main workbench. On the one hand, it is difficult to conveniently clean the iron chips on the main workbench, and on the other hand, the retention of the iron chips will also affect the stable operation of the drilling machine. Summary of the Invention

[0005] The present invention provides a drilling device for machining the base of a pump unit, aiming to solve the problem in the related technology that it is difficult to conveniently clean the iron chips on the main workbench with a sub-workbench installed.

[0006] A drilling device for machining the base of a pump unit, comprising a main workbench and a sub-workbench arranged on a drilling machine. Along the length direction of the T-shaped groove on the main workbench, a first scraping member is slidably arranged through a first elastic member, and a third scraping member is slidably arranged through a sixth elastic member. The first scraping member and the third scraping member respectively abut against the sub-workbench and are symmetric about the sub-workbench. At both ends of the main workbench along the length direction of the first scraping member, second scraping members are respectively arranged. The first scraping member and the third scraping member respectively have overlapping parts with the second scraping members. On the main workbench, lead screws are rotatably arranged to respectively drive the two second scraping members to slide along the length direction of the T-shaped groove. A base is installed on the lead screw, and a housing is slidably arranged on the base in the vertical direction. The second scraping member is connected to the base through two second elastic members and can slide relative to the base along the length direction of the T-shaped groove. The second scraping member is slidably connected to the base in the vertical direction. At both ends of the main workbench along the length direction of the T-shaped groove, waste hoppers are respectively slidably arranged. Inside the main workbench, a push plate corresponding to the base is slidably arranged through a third elastic member. The push plate is connected to a sliding plate through a connecting rod. When the sliding plate approaches or moves away from the lead screw in the horizontal direction, the push plate can slide up or down. A receiving groove is opened on the main workbench. When the base abuts against the sliding plate, the second scraping member can fall into the receiving groove. When the base disengages from abutting against the sliding plate, the push plate can push the second scraping member out of the receiving groove upward.

[0007] In the present invention, by rotating the lead screw, the first scraping member, the second scraping member, and the third scraping member can conveniently clean the iron filings on the upper end surface of the main workbench and in the T-shaped groove. The setting of the overlapping part facilitates the convenient reset of the first scraping member by the abutment of the second scraping member and the convenient reset of the third scraping member by the abutment of the second scraping member on one hand, and facilitates the comprehensive cleaning of the upper end surface of the main workbench on the other hand.

[0008] Preferably, the third scraping member and the first scraping member have the same structure. The first scraping member includes a first scraping plate for cleaning the upper surface of the main workbench and a second scraping plate for cleaning the T-shaped groove corresponding to the first scraping member. The second scraping member includes a third scraping plate for cleaning the upper surface of the main workbench and a fourth scraping plate for cleaning the T-shaped groove corresponding to the second scraping member. The overlapping part of the first scraping member and the second scraping member is the contact part of the first scraping plate and the third scraping plate, and the fourth scraping plate is slidably connected to the third scraping plate. The cooperation of the first scraping plate and the third scraping plate is beneficial to effectively clean the upper surface of the main workbench, and the cooperation of the second scraping plate and the fourth scraping plate is beneficial to effectively clean the T-shaped groove.

[0009] Preferably, a first guiding member is slidably arranged on the first scraping member through a fourth elastic member. The first guiding member includes a first sliding rod slidably connected to the first scraping member and a first sliding block fixedly connected to the first sliding rod. A sliding groove cooperating with the first sliding block is opened in the T-shaped groove corresponding to the first scraping member, and a sliding hole cooperating with the first sliding rod is opened inside the main workbench. A second guiding member is installed on the third scraping member through a seventh elastic member, and the second guiding member and the first guiding member have the same structure.

[0011] Preferably, a guide wheel is rotatably provided in the main workbench. A first traction rope is fixedly provided on the first scraping member. One end of the first traction rope away from the first scraping member bypasses the guide wheel and is fixedly connected to one end of the first elastic member, and the other end of the first elastic member is fixedly connected to the main workbench. The first elastic member and the sixth elastic member are respectively enclosed in the workbench. The principle that the third scraping member is connected to the main workbench through the sixth elastic member is the same as the principle that the first scraping member is connected to the main workbench through the first elastic member; the setting of the first traction rope and the first elastic member facilitates the cleaning of the iron filings on the upper end surface of the main workbench by the first scraping member after the first scraping member is unlocked.

[0012] Preferably, one end of the sliding plate facing the lead screw has a guiding portion for cooperating with the base, and the sliding plate is slidably connected to the main workbench through a fifth elastic member; the setting of the guiding portion facilitates the base to smoothly cross the sliding plate during the abutting process between the base and the sliding plate.

[0013] Preferably, the third scraping plate is slidably connected to the housing. Two second elastic members are respectively located on both sides of the third scraping plate along the length extension direction of the T-shaped groove. One end of the second elastic member is fixedly connected to the third scraping plate, and the other end is fixedly connected to the housing; the setting of the two second elastic members is beneficial to the reset of the third scraping plate.

[0014] Preferably, the upper end of the pushing plate has a top plate. When the base is disengaged from abutting against the sliding plate, the pushing plate can push the third scraping plate out of the receiving groove upward through the top plate.

[0015] Preferably, both ends of the main workbench along the length extension direction of the T-shaped groove respectively have a blanking channel communicated with the T-shaped groove. Two waste hoppers are respectively located below the corresponding blanking channels.

Detailed implementation manners

[0028] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0029] Refer to Figures 1-6 , a drilling device for machining the base of a pump unit, including a main workbench 10 and a sub-workbench 50 provided on a drilling machine. The sub-workbench 50 is installed in the middle of the upper end of the main workbench 10. Along the length direction of the T-shaped groove 11 on the main workbench 10, a first scraping member is slidably provided through a first elastic member 20, and a third scraping member is slidably provided through a sixth elastic member 70. The first elastic member 20 and the sixth elastic member 70 are springs. The first scraping member and the third scraping member respectively abut against the sub-workbench 50 and are symmetric about the sub-workbench 50. In this embodiment, there are three T-shaped grooves 11. The first scraping member includes a first scraper 21 for cleaning the upper surface of the main workbench 10 and a second scraper 22 for cleaning the T-shaped groove 11 in the middle of the main workbench 10. The second scraper 22 is slidably connected to the corresponding T-shaped groove 11.

[0030] The scraping member three has the same structure as the scraping member one. The scraping member three includes a scraping plate five 71 corresponding to the scraping plate one 21 and a scraping plate six 72 corresponding to the scraping plate two 22. The scraping plate six 72 is slidably connected to the T-shaped groove 11 corresponding to the scraping plate two 22. A guiding member one is slidably provided on the scraping plate two 22 through an elastic member four 231. A guiding member two is installed on the scraping member three through an elastic member seven 76. The guiding member two and the guiding member one have the same structure. The elastic member four 231 and the elastic member seven 76 respectively adopt springs. The guiding member one includes a sliding rod one 23 slidably connected to the scraping plate two 22 and a sliding block one 24 fixedly connected to the sliding rod one 23. There are two sliding rods one 23. The elastic member four 231 is sleeved on the outer periphery of the sliding rod one 23. The two ends of the elastic member four 231 respectively abut against the scraping plate two 22 and the sliding block one 24. A sliding groove 111 matching the sliding block one 24 is formed in the T-shaped groove 11 corresponding to the scraping plate two 22. A guide wheel 16 is rotatably provided in the main workbench 10. A traction rope one 25 is fixedly provided on the scraping plate two 22. One end of the traction rope one 25 away from the scraping plate two 22 bypasses the guide wheel 16 and is fixedly connected to one end of the elastic member one 20. The other end of the elastic member one 20 is fixedly connected to the main workbench 10.

[0031] The guiding member two includes a sliding rod two 73 slidably connected to the scraping plate six 72 and a sliding block two 74 fixedly connected to the sliding rod two 73. The elastic member seven 76 is sleeved on the outer periphery of the sliding rod two 73. The two ends of the elastic member seven 76 respectively abut against the scraping plate six 72 and the sliding block two 74. A traction rope two 75 is fixedly provided on the scraping plate six 72. In this embodiment, through holes 60 for the traction rope one 25 and the traction rope two 75 to pass through are respectively formed at both ends of the sliding block one 24 along the length extension direction of the scraping plate one 21 and at both ends of the sliding block two 74 along the length extension direction of the scraping plate five 71.

[0032] The elastic member one 20 and the elastic member six 70 are respectively wrapped in the main workbench 10 to prevent the elastic member one 20 and the elastic member six 70 from contacting the iron filings, thereby ensuring the stable operation of the elastic member one 20 and the elastic member six 70. Locking buckles 13 for locking the scraping member one and the scraping member three are respectively rotatably provided at both ends of the main workbench 10 along the length extension direction of the T-shaped groove 11. In this embodiment, the principle of connecting the scraping member three to the main workbench 10 through the elastic member six 70 is the same as the principle of connecting the scraping member one to the main workbench 10 through the elastic member one 20. Taking the principle of connecting the scraping member one to the main workbench 10 through the elastic member one 20 as an example, when the locking buckle 13 is buckled on the scraping plate one 21 to lock the scraping member one, the elastic member one 20 is in a stretched state. At this time, the traction rope one 25 and the elastic member one 20 form a U-shaped structure. When the operator unlocks the locking buckle 13 from the scraping plate one 21, the elastic member one 20 can quickly contract and drive the scraping member one to slide rapidly along the length direction of the T-shaped groove 11 through the traction rope one 25, so as to scrape the iron filings on the upper surface of the main workbench 10 corresponding to the scraping plate one 21 and the iron filings in the T-shaped groove 11 corresponding to the scraping plate two 22.

[0033] The two ends of the first slider 24 along the direction perpendicular to the length extension direction of the T-shaped groove 11 are in sliding fit with the inner wall of the sliding groove 111, so as to facilitate the first slider 24 to scrape the iron filings remaining in the sliding groove 111 during the sliding process. The first slider 24 has a guiding surface 241, and the guiding surface 241 is inclined to prevent the iron filings on the upper surface of the main workbench 10 from accumulating on the first slider 24 when entering the T-shaped groove 11. At both ends of the main workbench 10 along the length direction of the T-shaped groove 11, sliding holes 102 matching with the first sliding rod 23 and the second sliding rod 73 are respectively provided. When the fourth elastic member 231 is squeezed, the first slider 24 can move towards the direction close to the second scraper 22, so that the two first sliding rods 23 extend into the corresponding sliding holes 102. At this time, the two first sliding rods 23 can stably support the second scraper 22; when the seventh elastic member 76 is squeezed, the second slider 74 can move towards the direction close to the sixth scraper 72, so that the two second sliding rods 73 extend into the corresponding sliding holes 102. At this time, the two second sliding rods 73 can stably support the sixth scraper 72.

[0034] At both ends of the main workbench 10 along the length extension direction of the first scraper 21, second scraping members are respectively provided. The two second scraping members are respectively matched with the T-shaped grooves 11 on the main workbench 10 close to its edge. The first scraping member and the third scraping member respectively have overlapping parts with the second scraping member. The second scraping member includes a third scraper 30 for cleaning the upper surface of the main workbench 10 and a fourth scraper 31 for cleaning the T-shaped groove 11 corresponding to the second scraping member. The overlapping part of the first scraping member and the second scraping member is the contact part of the first scraper 21 and the third scraper 30. The overlapping part of the third scraping member and the second scraping member is the contact part of the fifth scraper 71 and the third scraper 30. The fourth scraper 31 is slidably connected to the third scraper 30. In this embodiment, the fourth scraper 31 has an adaptation groove 311, the lower end of the third scraper 30 has an adaptation plate 302 slidably matched with the adaptation groove 311, and the lower end of the adaptation plate 302 has a limiting part 303 for preventing the fourth scraper 31 from falling off the third scraper 30.

[0035] On the main workbench 10, lead screws 14 are rotatably provided for respectively driving the two second scraping members to slide along the length direction of the T-shaped groove 11. At both ends of the main workbench 10 along the direction perpendicular to the length extension direction of the T-shaped groove 11, fitting grooves 104 for installing the lead screws 14 are respectively provided. In this embodiment, a motor 12 is installed in the main workbench 10. The end parts of the two lead screws 14 are coaxially provided with chain wheels 141 respectively, and the two chain wheels 141 are driven by a chain. The end part of one of the lead screws 14 is connected to the output end of the motor 12. Thus, when the motor 12 rotates, the two lead screws 14 can rotate synchronously.

[0036] Reference Figures 5-9, a base 32 is in threaded fit with the lead screw 14. The base 32 is slidably connected to the mating groove 104. The lower end surface of the base 32 and the two side surfaces along the direction perpendicular to the length extension direction of the T-shaped groove 11 are respectively in sliding fit with the inner wall of the mating groove 104. A housing 33 is slidably provided on the base 32 in the vertical direction. The two sides of the housing 33 along the direction perpendicular to the length extension direction of the T-shaped groove 11 are in sliding fit with the mating groove 104. The third scraper 30 is slidably connected to the housing 33 through two second elastic members 301, so that the third scraper 30 can slide relative to the base 32 along the length extension direction of the T-shaped groove 11. The second elastic member 301 is specifically a spring. The two second elastic members 301 are respectively located on both sides of the third scraper 30 along the length extension direction of the T-shaped groove 11. Taking one of the second elastic members 301 as an example, one end of the second elastic member 301 is fixedly connected to the third scraper 30, and the other end is fixedly connected to the housing 33. It can be understood that when the third scraper 30 is located on the upper end surface of the main workbench 10 and does not abut against the first scraper 21, the pushing forces of the two second elastic members 301 on the third scraper 30 are the same and the third scraper 30 is located in the middle of the housing 33 and the base 32.

[0037] A push plate 40 corresponding to the base 32 is slidably provided in the main workbench 10 through a third elastic member 41. The third elastic member 41 is specifically a spring. The push plate 40 is connected to a sliding plate 43 through a connecting rod 42. The sliding plate 43 can slide in the horizontal direction. In this embodiment, there are two connecting rods 42, and both ends of the connecting rod 42 are rotatably connected to the push plate 40 and the sliding plate 43 respectively. The sliding plate 43 is slidably connected to the main workbench 10 through a fifth elastic member 432. The fifth elastic member 432 is a spring. One end of the sliding plate 43 facing the lead screw 14 has a guiding portion 431 that cooperates with the base 32. The guiding portion 431 is approximately triangular in structure. When the sliding plate 43 slides horizontally closer to or farther away from the lead screw 14, the push plate 40 can slide up or down. When the base 32 does not abut against the sliding plate 43, under the action of the third elastic member 41, the guiding portion 431 extends into the mating groove 104.

[0038] At the upper end of the main workbench 10, a receiving groove 101 is provided for mating with the third scraper 30. The upper end of the pushing plate 40 has a top plate 401 that is slidably mated with the receiving groove 101. The first scraping member and the third scraping member respectively abut against the secondary workbench 50, and the base 32 abuts against the sliding plate 43. When the sliding plate 43 is completely received into the main workbench 10, the sliding plate 43 can drive the pushing plate 40 to move downward, so that the top plate 401 moves below the receiving groove 101. At this time, under the action of its own weight, the second scraping member can make the third scraper 30 fall into the receiving groove 101. At this time, the upper end surface of the third scraper 30 is flush with the upper end surface of the main workbench 10. When the lead screw 14 rotates and drives the base 32 to slide, so that the base 32 is disengaged from abutting against the sliding plate 43, the third scraper 30 will not immediately disengage from the receiving groove 101. Since the third scraper 30 falls into the receiving groove 101, the third scraper 30 will have relative sliding with the housing 33 on the base 32. One of the two elastic members 301 at both ends of the third scraper 30 will continue to be compressed on the original basis, and the other will be elongated on the original basis. During this process, the elastic member 41 can push the pushing plate 40 upward, and the pushing plate 40 can push the third scraper 30 located in the receiving groove 101 upward through the top plate 401, so as to push the third scraper 30 out of the receiving groove 101 upward. At this time, the upper end surface of the top plate 401 is flush with the upper end surface of the main workbench 10. Subsequently, under the action of the two elastic members 301 at both ends of the third scraper 30, the third scraper 30 can be reset and move to the middle of the housing 33 and the base 32. Subsequently, when the lead screw 14 continues to rotate and drives the base 32 to slide, the third scraper 30 can move with the base 32.

[0039] It should be noted that when the lower end surface of the third scraper 30 abuts against the upper end surface of the main workbench 10, the limiting portion 303 abuts against the top of the mating groove 311. When the third scraper 30 falls into the receiving groove 101, the upper end surface of the third scraper 30 is flush with the upper end surface of the main workbench 10, and the limiting portion 303 moves downward relative to the mating groove 311 and the limiting portion 303 is disengaged from abutting against the top of the mating groove 311.

[0040] Reference Figures 1-5 , at both ends of the main workbench 10 along the length direction of the T-shaped groove 11, waste hoppers 15 are respectively slidably provided. The length extension direction of the waste hoppers 15 is perpendicular to the length extension direction of the T-shaped groove 11. At both ends of the main workbench 10 along the length extension direction of the T-shaped groove 11, there are blanking channels 103 respectively communicating with the three T-shaped grooves 11 and the two mating grooves 104. The two waste hoppers 15 are respectively located below the corresponding blanking channels 103. In this embodiment, the bottom of the T-shaped groove 11 and the bottom of the mating groove 104 are on the same plane, and the upper end surface of the waste hopper 15 is lower than or equal to the bottom of the T-shaped groove 11, so as to facilitate the first scraping member and the second scraping member to smoothly scrape the iron filings into the waste hoppers 15. On the one hand, it realizes the convenient cleaning of the iron filings on the main workbench 10 to ensure the stable operation of the drilling machine. On the other hand, it realizes the centralized recovery of the iron filings, which is convenient for the recycling of resources.

[0041] Specific working principle: Refer to Figures 1-9 , in the initial state, scraping member one and scraping member three respectively abut against both ends of the sub-workbench 50 along the length direction of the T-shaped groove 11, the first elastic member 20 and the sixth elastic member 70 are respectively in a stretched state, the base 32 abuts against the sliding plate 43 and the sliding plate 43 is completely received in the main workbench 10, the third scraper 30 falls into the receiving groove 101 and the end of the third scraper 30 close to the sub-workbench 50 fits against the sub-workbench 50.

[0042] When the workpiece placed on the sub-workbench 50 is processed, the iron filings on the sub-workbench 50 can be manually cleaned onto the main workbench 10 first, and then the motor 12 is controlled to synchronously rotate the two lead screws 14 so that the base 32 moves along the mating groove 104 to the end of the mating groove 104 close to the rocker arm seat 17. During this process, the third scraper 30 can disengage from the receiving groove 101 and move to the upper surface of the main workbench 10 and move with the base 32. During the movement of the third scraper 30, it can abut against the first scraper 21 and drive it to move, so that the first scraper 21 cleans the iron filings on the upper surface of the corresponding main workbench 10 into the waste hopper 15 at the end close to the rocker arm seat 17, the second scraper 22 cleans the iron filings in the corresponding T-shaped groove 11 into the waste hopper 15 at the end close to the rocker arm seat 17, the third scraper 30 cleans the iron filings on the upper surface of the corresponding main workbench 10 into the waste hopper 15 at the end close to the rocker arm seat 17, the fourth scraper 31 can clean the iron filings in the corresponding T-shaped groove 11 into the waste hopper 15 at the end close to the rocker arm seat 17, and the base 32 can clean the iron filings in the corresponding mating groove 104 into the waste hopper 15 at the end close to the rocker arm seat 17.

[0043] Then the motor 12 is controlled to synchronously rotate the two lead screws 14 so that the base 32 moves along the mating groove 104 to the end of the mating groove 104 away from the rocker arm seat 17. During this process, the first scraping member can reset to the initial state, the third scraper 30 can first enter the receiving groove 101 and then disengage from the receiving groove 101 and move to the upper surface of the main workbench 10 and move with the base 32. During the movement of the third scraper 30, it can abut against the fifth scraper 71 and drive it to move, so that the fifth scraper 71 cleans the iron filings on the upper surface of the corresponding main workbench 10 into the waste hopper 15 at the end away from the rocker arm seat 17, the sixth scraper 72 cleans the iron filings in the corresponding T-shaped groove 11 into the waste hopper 15 at the end away from the rocker arm seat 17, the third scraper 30 cleans the iron filings on the upper surface of the corresponding main workbench 10 into the waste hopper 15 at the end away from the rocker arm seat 17, the fourth scraper 31 can clean the iron filings in the corresponding T-shaped groove 11 into the waste hopper 15 at the end away from the rocker arm seat 17, and the base 32 can clean the iron filings in the corresponding mating groove 104 into the waste hopper 15 at the end away from the rocker arm seat 17.

[0044] Subsequently, control the two lead screws 14 to rotate synchronously so that the third scraper 30 falls into the receiving groove 101, and thus the cleaning of the iron filings is completed.

[0045] When the auxiliary workbench 50 is not installed on the main workbench 10, the process of cleaning the iron filings on the main workbench 10 is as follows: In the initial state, the two latches 13 are respectively buckled on the first scraper 21 and the fifth scraper 71. The first scraping member is locked at one end of the main workbench 10 close to the rocker arm seat 17, and the third scraping member is locked at the end of the main workbench 10 far from the rocker arm seat 17. At this time, the first scraping member is located in the blanking channel 103 close to the rocker arm seat 17 and abuts against the side surface of the blanking channel 103. The third scraping member is located in the blanking channel 103 far from the rocker arm seat 17 and abuts against the side surface of the blanking channel 103. The first slider 24 is located in the sliding groove 111 to support the first scraping member. The second slider 74 is located in the sliding groove 111 to support the third scraping member. The first elastic member 20 and the sixth elastic member 70 are respectively in a stretched state. The base 32 abuts against the sliding plate 43 and the sliding plate 43 is completely received in the main workbench 10, and the third scraper 30 falls into the receiving groove 101.

[0046] Subsequently, manually rotate the latch 13 to unlock the first scraping member, and then control the two lead screws 14 to rotate synchronously so that the base 32 moves along the mating groove 104 to the end of the mating groove 104 far from the rocker arm seat 17. During this process, the first scraping member can always abut against the second scraping member under the action of the first elastic member 20 and can move together with the second scraping member. The third scraper 30 slides relative to the housing 33, and the second elastic member 301 located on the side of the housing 33 far from the first scraper 21 on the side of the third scraper 30 will continue to be compressed on the original basis, and the second elastic member 301 located on the side of the housing 33 close to the first scraper 21 on the side of the third scraper 30 will be elongated on the original basis. Therefore, when the base 32 is about to abut against the sliding plate 43, since the first scraping member and the second scraping member are in an abutting state and the upper end surface of the top plate 401 is flush with the upper end surface of the main workbench 10, the third scraper 30 has crossed the receiving groove 101, so that the base 32 can smoothly move along the mating groove 104 to the end of the mating groove 104 far from the rocker arm seat 17. It should be noted that at this time, the first scraper 21 can squeeze the second slider 74 through the first slider 24 under the action of the first elastic member 20, so that the second slide bar 73 enters the corresponding slide hole 102. At this time, the two second slide bars 73 can stably support the sixth scraper 72, and the fourth elastic member 231 and the seventh elastic member 76 are squeezed. At this time, the first scraping member can scrape the iron filings on the upper end surface of the corresponding main workbench 10 and the iron filings in the T-shaped groove 11 to the waste hopper 15 at the end far from the rocker arm seat 17, and the second scraping member can scrape the iron filings on the upper end surface of the corresponding main workbench 10, the iron filings in the mating groove 104 and the iron filings in the T-shaped groove 11 to the waste hopper 15 at the end far from the rocker arm seat 17.

[0047] It can be understood that subsequently, during the process of controlling the synchronous rotation of the two lead screws 14 to move the base 32 along the mating groove 104 to the end of the mating groove 104 close to the rocker arm seat 17, the second scraping member can abut against the first scraping member, so that the first scraping member moves to the end of the main workbench 10 close to the rocker arm seat 17. Subsequently, manually pull the first scraping member to make the first scraping member abut against the side surface of the blanking channel 103, and then lock it through the lock 13. Subsequently, control the synchronous rotation of the two lead screws 14 so that the third scraper 30 falls into the receiving groove 101, and thus the cleaning of the iron filings is completed.
