Description

[0002] In the field of mechanical processing, the gantry machining center is widely used in the milling, boring and other machining processes of large parts as a high-precision and high-efficiency machining equipment. The workbench is the core component of the gantry machining center, the fixture table of which is used to carry the workpiece and realize the feeding movement through the driving component, and the multiple sets of positioning grooves arranged on the fixture table along the movement direction are used for the accurate positioning of the workpiece, which directly affects the machining precision.

[0003] However, the metal scraps (such as iron scraps, aluminum scraps, etc.) generated in the machining process are extremely easy to accumulate in the positioning grooves, and if not cleaned in time, it will cause the positioning deviation of the workpiece, the jamming of the driving component and other problems, which seriously affects the machining quality and the service life of the equipment. In the prior art, the processing methods of the positioning groove scraps are mainly divided into two categories: one is manual cleaning, which needs to be operated when the machine is stopped, not only reduces the machining efficiency, but also has safety hazards; the other is to use an active cleaning device (such as a brush roller, a gas blowing mechanism, etc.) driven by an additional power source, which needs an independent power source and control system, not only increases the manufacturing cost of the equipment, but also needs to make a large modification to the original structure of the workbench, and the adaptability is poor.

[0004] Especially in the batch production scene, the frequent reciprocating movement of the fixture table makes the positioning groove scrapes accumulate quickly, especially the long roll of scrapes, and the conventional cleaning method is difficult to clean the positioning grooves on the fixture table, and the existing processing method is difficult to realize efficient cleaning while ensuring the continuity of machining. Therefore, how to utilize the existing driving components and structural features of the workbench to realize the passive design (i.e. without relying on additional power, but relying on the movement of the fixture table itself to realize the cleaning of the scrapes) becomes a key problem to simplify the structure of the equipment, reduce the cost and improve the efficiency of the scrapes processing.

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0036] As Figures 1 to 11 shown: the application provides a gantry machining center, which comprises a gantry body 10, a support base 20, a workbench 30, a first cleaning assembly 40, a second cleaning assembly 50 and a limiting assembly 60; the gantry body 10 is used for mounting a bearing machining tool, the support base 20 is used for supporting the workbench 30, the workbench 30 is used for placing a part to be machined, a large amount of waste will fall on the workbench during the machining process of the part, the first cleaning assembly 40 and the second cleaning assembly 50 are respectively used for cutting and crushing the waste on the workbench for multiple times, and the limiting assembly 60 is used for gathering the waste to facilitate the first cleaning assembly 40 and the second cleaning assembly 50 to crush and cut.

[0037] ​The support base 20 is arranged below the gantry body 10, the workbench 30 is arranged on the support base 20 in an axial sliding manner, two guide rails 21 are symmetrically arranged on the support base 20 and are spaced apart along the axial direction of the support base 20, the lower ends of the workbench 30 are clamped on the guide rails 21, a driving motor 22 is arranged between the two guide rails 21, the fixed end of the driving motor 22 is arranged on the support base 20, the output shaft of the driving motor 22 is in transmission connection with a guide rod 23, the two ends of the guide rod 23 are rotatably arranged on the support base 20, the guide rod 23 is parallel to the guide rails 21, a connecting block 31 is arranged at the lower end of the workbench 30, the connecting block 31 penetrates through the guide rod 23, the guide rod 23 is provided with threads, the connecting block 31 is in threaded connection with the guide rod 23, and a sleeve 25 is also arranged on the guide rod 23 in a sliding manner, the sleeve 25 is arranged on the side of the connecting block 31 close to the driving motor 22, and the connecting block 31 moves synchronously with the sleeve 25. During normal operation, the workbench 30 can reciprocally slide on the support base 20, so that the machining tool on the gantry body 10 can process the parts to be processed.

[0038] In order to provide a support structure for the first cleaning assembly 40 and the second cleaning assembly 50 and collect the cutting and crushing waste, a collecting groove 24 is arranged on one side of the support base 20, the collecting groove 24 is arranged below the guide rod 23, the workbench 30 can reciprocally slide above the collecting groove 24, a support 70 is arranged above the collecting groove 24, the first cleaning assembly 40 is vertically arranged on the support 70, the lower end of the first cleaning assembly 40 penetrates through the support 70 and is arranged above the collecting groove 24, so that the long roll waste can be divided into short waste, and the second cleaning assembly 50 is horizontally arranged on the side wall away from the workbench 30 of the support 70, part of the structure of the second cleaning assembly 50 can be inserted into the positioning groove 31 of the workbench 30, and the waste in the positioning groove 31 is pushed to the collecting groove 24. Due to the existence of the sleeve 25, the waste will not fall and adhere to the guide rod 23, so that the stability of the guide rod 23 is ensured.

[0039] The support 70 comprises a top plate 71, a side plate 72 and a rear plate 73, the top plate 71, the side plate 72 and the rear plate 73 form a structure with an open lower end and an open side end close to the support base 20, the second cleaning assembly 50 is connected with the rear plate 73, the first cleaning assembly 40 is arranged on the top plate 71, the rotating plate 61 is arranged on the lower surface of the top plate 71, and the limiting piece 62 is movably connected with the top plate 71; the structure of the open side end facilitates the movement of the workbench 30 to the lower side of the first cleaning assembly 40 and the second cleaning assembly 50, and the structure of the open lower end facilitates the removal of the workbench 30, so that the waste can be delivered to the collecting groove 24.

[0040] The first cleaning assembly 40 comprises a transmission motor 41, a synchronous part 42 and two cutting parts 43. The fixed end of the transmission motor 41 is arranged on the top plate 71, and the transmission motor 41 is arranged vertically. The output shaft of the transmission motor 41 is in transmission connection with one cutting part 43. The two cutting parts 43 are arranged vertically and in parallel with each other. The synchronous part 42 is arranged between the two cutting parts 43 and can drive the two cutting parts 43 to rotate synchronously and reversely. The cutting part 43 comprises a driving shaft 431 and a cutting blade 432. The upper end of the driving shaft 431 of one cutting part 43 is in transmission connection with the output shaft of the transmission motor 41. The driving shaft 431 penetrates downward through the top plate 71 and is in rotation connection with the top plate 71. The cutting blade 432 is arranged circumferentially on the driving shaft 431. The cutting blades 432 on the two driving shafts 431 are distributed in a staggered manner. The synchronous part 42 comprises a driving wheel 421, a driven wheel 422 and a synchronous belt 423. The driving wheel 421 and the driven wheel 422 are not located on the same horizontal plane. The driving wheel 421 and the driven wheel 422 are respectively sleeved on the two driving shafts 431. The synchronous belt 423 is arranged in an eight-shaped manner on the driving wheel 421 and the driven wheel 422. The staggered height of the driving wheel 421 and the driven wheel 422 can prevent the eight-shaped intersection of the synchronous belt 423 from being in contact, avoid friction caused by the contact of the synchronous belt 423 itself, prolong the service life of the synchronous belt 423 and ensure the stability of the transmission of the synchronous belt 423. The staggered height is set according to the size of the driving wheel 421 and the driven wheel 422, which is not limited in the embodiment. The eight-shaped connection mode can make the driving wheel 421 and the driven wheel 422 rotate in opposite directions, which is convenient for the two cutting blades 432 to better cut and crush the long roll of waste scraps.

[0041] In one embodiment, the two cutting blades 432 can be columnar structures with hook-shaped protrusions on the outer periphery. The staggered arrangement is configured such that the protruding structures of the two cutting blades 432 partially overlap on the projection plane. This staggered arrangement can make the cutting blades 432 more effectively tear and crush the long roll of scraps during rotation, improving the crushing effect.

[0042] In another embodiment, the two cutting blades 432 can be arranged in a similar meshing manner. The outer periphery of each cutting blade 432 is provided with a toothed structure that is adapted to each other. The tooth positions of the two cutting blades 432 are distributed in a staggered manner along the axial direction. The tooth positions of the toothed protrusions are distributed in a staggered manner along the circumferential direction of the shaft. A small gap of 0.5-2mm is reserved between the toothed protrusions. This similar meshing arrangement can make the two cutting blades 432 mesh with each other like gears during rotation, shearing and crushing the long roll of scraps, further improving the crushing effect.

[0043] The cleaning process of the first cleaning assembly 40 is as follows:

[0044] When the workbench 30 completes the part machining task, the driving motor 22 drives the guide rod 23 to rotate, so that the workbench 30 can slide on the support base 20 to the side close to the support 70. When the workbench 30 slides to the lower side of the support 70, the long waste on the surface of the workbench 30 is cut into smaller waste by the rotation of the two cutting blades 432.

[0045] The second cleaning assembly 50 includes a scraper plate 51 and a plurality of scraper strips 52. The scraper plate 51 is horizontally arranged, and the height of the scraper plate 51 is not less than the height of the workbench 30. The plurality of scraper strips 52 are arranged on the lower surface of the scraper plate 51. The cross-sectional dimension of the plurality of scraper strips 52 is consistent with the cross-sectional dimension of the positioning groove on the workbench 30. The spacing between the plurality of scraper strips 52 is consistent with the spacing between the positioning grooves on the workbench 30. The scraper plate 51 is connected to the side of the rear plate 73 away from the workbench 30 through a connecting plate.

[0046] The cleaning process of the second cleaning assembly 50 is as follows:

[0047] During the crushing and cutting process of the first cleaning assembly 40, the workbench 30 continues to slide until the scraper plate 51 is close to the upper surface of the workbench 30. At this time, the scraper strips 52 are aligned with the positioning grooves 31 on the workbench 30. The workbench 30 continues to move, and the scraper strips 52 push the waste in the positioning grooves 31 out. The scraper plate 51 pushes the waste on the surface of the workbench 30 out. When the workbench 30 moves away from the scraper strips 52 and the scraper plate 51, the waste is pushed onto the collecting groove 24.

[0048] During the cutting and crushing cleaning process, the working process is as follows: the first cleaning assembly 40 cuts and crushes, and the second cleaning assembly 50 pushes the waste after cutting and crushing from the workbench 30 to the collecting groove 24. Through the cooperation of the first cleaning assembly 40 and the second cleaning assembly 50, the waste on the workbench 30 can be completely cleaned.

[0049] Since the waste on the workbench 30 is scattered on the entire surface of the workbench 30, in order to better collect the waste, the limiting assembly 60 is further arranged on the lower surface of the support 70, which can collect and gather the waste, and facilitate the crushing process of the first cleaning assembly 40.

[0050] The limiting assembly 60 includes two rotating plates 61 symmetrically arranged on the lower surface of the support 70. The two rotating plates 61 are rotatably connected to the support 70 at the end close to each other, that is, two symmetrically arranged fixed plates 74 are arranged on the lower surface of the support 70. The fixed plates 74 are vertically arranged, and each rotating plate 61 is rotatably connected to the corresponding fixed plate 74. The other end of the two rotating plates 61 can rotate in the opposite direction around the end of the rotating plate 61 connected to the support 70. The two rotating plates 61 form an eight-shaped structure, and the two rotating plates 61 and the support 70 form a processing area, which can collect and gather the waste.

[0051] In order to position the rotating plate 61 and keep the fixed angle, a limiting part 62 is arranged on each rotating plate 61 for positioning the position of the rotating plate 61. Two symmetrical arc-shaped grooves 712 are formed on the top plate 71, the arc of the arc-shaped groove 712 is consistent with the arc of the rotating plate 61, the limiting part 62 comprises a rotating shaft 621, a connecting rod 622, a protruding block 623 and a positioning pin 624, the rotating shaft 621 is rotatably arranged on the top plate 71, the rotating shaft 621 is rotatably connected with one end of the rotating plate 61 and the fixed plate 74 and is on the same axis in the vertical plane, the protruding block 623 is arranged on the rotating plate 61 through the arc-shaped groove 712, the protruding block 623 can slide along the groove in the arc-shaped groove 712, one end of the connecting rod 622 is connected with the rotating shaft 621, the other end of the connecting rod 622 is connected with the protruding block 623, a plurality of positioning holes 711 are formed on the top plate 71, the positioning pin 624 is inserted into the connecting rod 622, the positioning pin 624 can be inserted into the positioning hole 711 of the top plate 71, the number and position of the positioning hole 711 can be adjusted according to the specific required rotating angle, which is not limited in the embodiment.

[0052] The opening and closing process of the rotating plate 61 is as follows:

[0053] According to the required angle, the protruding block 623 on each rotating plate 61 is moved, so that the rotating plate 61 is rotated to the set position, and then the positioning pin 624 is used to lock with the top plate 71 to fix the angle of the rotating plate 61.

[0054] Meanwhile, before the first cleaning assembly 40 is cut, a pre-cutting component, the third cleaning assembly 80, is arranged, the first cleaning assembly 40 and the third cleaning assembly 80 are in transmission connection, the driving source of the first cleaning assembly 40 is used as the common driving source, the third cleaning assembly 80 comprises two transmission shafts 81, a pushing plate 82, a support frame 83 and a cutting plate 84, the two transmission shafts 81 are horizontally and spaced apart rotatably arranged on the top plate 71, one end of each of the two transmission shafts 81 is in transmission connection with the two driving shafts 431, a cam 89 is arranged on each of the two transmission shafts 81, the cam 89 abuts against the pushing plate 82, the lower end of the pushing plate 82 is arranged on the support frame 83 through the top plate 71, a plurality of return springs 90 are arranged between the pushing plate 82 and the top plate 71, the cutting plate 84 is arranged at the lower end of the support frame 83, the support frame 83 and the cutting plate 84 are elastically connected, the cutting plate 84 can be driven by the support frame 83 to approach the collecting groove 24 and cut the waste. In the embodiment, the number of the cutting plate 84 is 2, the two cutting plates 84 are spaced apart, in actual use, the number of the cutting plate 84 can be adjusted according to the specific condition, which is not limited in the embodiment.

[0055] The upper end of the cutting plate 84 is internally hollow, the lower end of the support frame 83 is inserted into the hollow structure of the cutting plate 84, a plurality of slide rods 85 are vertically arranged between the horizontal end of the support frame 83 and the horizontal end of the cutting plate 84, and a buffer spring 86 is sleeved on each slide rod 85. The driving shaft 431 is provided with a driving bevel gear 87, and the transmission shaft 81 is provided with a driven bevel gear 88 close to the side of the driving shaft 431, and the driving bevel gear 87 and the driven bevel gear 88 are meshed with each other.

[0056] The working process of the third cleaning assembly 80 is as follows:

[0057] After the transmission motor 41 is started, the driving shaft 431 connected with the transmission motor 41 is driven to rotate, then the driving wheel 421 on the driving shaft 431 drives the corresponding transmission shaft 81 to rotate, and at the same time, the other driving shaft 431 is driven to rotate through the synchronous belt 423, and the driven wheel 422 on the driving shaft 431 also drives the corresponding transmission shaft 81 to rotate, so that the two transmission shafts 81 are synchronously rotated; then, the cam 89 on the transmission shaft 81 is synchronously rotated with the transmission shaft 81, then the cam 89 intermittently pushes the pushing plate 82 downward, at this time, the return spring 90 is compressed, then the pushing plate 82 pushes the support frame 83, the support frame 83 moves downward to drive the cutting plate 84 to cut the long scrap; when the cutting plate 84 contacts the scrap, if the scrap is soft (such as thin scrap), at this time, the buffer spring 86 is compressed with a small amount (low degree of deformation), and the elastic force is moderate, so that the cutting can be stable; if hard nodules, thick scrap or foreign matters (such as bolts and welding slag) beyond the cutting capacity are encountered, at this time, the compression stroke of the pushing plate 82 has not been completed, and the support frame 83 will be further compressed, then due to the existence of the foreign matters, the buffer spring 86 will be further compressed (a large deformation is generated), and the elastic force will not instantaneously increase (compared with the “hard collision” of the rigid driving), so that part of the impact force is absorbed through the deformation, and the cutting plate 84 is protected from being cracked or wound due to instantaneous overload. When the pressure applied by the cam 89 on the pushing plate 82 disappears, the buffer spring 86 and the return spring 90 are rebounded.

[0058] Through the cooperative work of the third cleaning assembly 80 and the first cleaning assembly 40, the gantry machining center can efficiently process the long scrap generated in the machining process, avoid the long scrap from winding the equipment components, improve the reliability and machining precision of the equipment, and prolong the service life of the equipment.

[0059] The scrap cleaning process of the gantry machining center is as follows:

[0060] When the parts on the workbench 30 are processed, the scrap needs to be cleaned up, at this time, the driving motor 22 is used to move the workbench 30 towards the support 70, then the scrap is gathered in the processing area by the two rotating plates 61, then the two cutting plates 84 of the third cleaning assembly 80 are periodically segmented to cut the long roll scrap into short segments for subsequent processing; then the cutting blades 432 on the two driving shafts 431 of the first cleaning assembly 40 will crush the short segment scrap, and the pre-processed roll scrap will be deeply crushed to form easy-to-recycle scrap; finally, the scrap after two crushing processes is pushed to the collection groove 24 by the second cleaning assembly 50, realizing continuous processing and centralized collection from long roll scrap to fine scrap, not only avoiding the failure caused by long roll scrap winding the equipment, but also improving the recycling rate of metal waste and reducing the cost of waste treatment.

[0061] It is apparent to those skilled in the art that the application is not limited to the details of the foregoing exemplary embodiments, and that the application can be implemented in other specific forms without departing from the spirit or essential characteristics of the application.
