Description

Technical Field

[0001] The invention relates to the technical field of gantry processing devices, in particular to a double-station turning and milling compound gantry processing center. Background Art

[0002] In the field of modern mechanical processing, the dual-station milling compound gantry machining center is a highly efficient and multifunctional processing equipment, which is widely used in the precision processing of various complex parts. This type of equipment integrates multiple processing processes such as turning and milling to achieve one-time clamping and multi-process processing of the workpiece, which significantly improves the processing efficiency and processing accuracy. However, although the dual-station milling compound gantry machining center of the prior art has made great progress in processing capabilities, it still has some obvious defects:

[0003] The existing dual-station milling compound gantry machining center has deficiencies in handling waste chips and stains generated during the machining process. The traditional cleaning method often relies on a fixed-position air nozzle or dust suction device. This method is prone to forming a cleaning blind spot when handling waste chips on the workbench surface and in the rectangular groove, resulting in the inability to completely remove the waste chips, thereby affecting the machining quality and the service life of the equipment.

This design not only improves the cleaning efficiency, but also ensures the comprehensive cleaning of the workbench surface; through the reciprocating motion of the lower tooth plate and the upper tooth plate, the vertical rod and the guide rod also move accordingly, thereby driving the knocking rod to reciprocately knock on the side wall of the workbench. This knocking action can more effectively remove stubborn stains and impurities attached to the surface of the workbench or in the gaps, thereby improving the thoroughness of cleaning; the reciprocating motion of the connecting plate not only assists in the knocking cleaning of the side wall of the workbench, but also through the push rod The first brush plate and the second brush plate are knocked and vibrated to effectively remove the waste sticking on the brush plates.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Embodiment 1: Combination Figure 1-Figure 9 As shown, the present invention provides a technical solution: a double-station turning and milling compound gantry machining center, comprising a base 1 and a double-station turning and milling assembly 3, a workbench 2 is slidably arranged on the top of the base 1, the double-station turning and milling assembly 3 is arranged above the workbench 2, and a cleaning assembly 4 is arranged on the workbench 2, the cleaning assembly 4 is used to clean the waste chips on the surface of the workbench 2 to ensure the cleanliness of the workbench 2 and the normal operation of the equipment;

[0031] A row of rectangular grooves 21 are provided on the upper surface of the workbench 2, and these rectangular grooves 21 are used to accommodate and guide the flow of waste chips. Slide grooves 22 are provided on both sides of the workbench 2, and these slide grooves 22 are used to install and fix other components, such as the cleaning component 4. The bottom of the workbench 2 is connected to a screw rod 23 through a thread, and a driving motor 24 is provided at one end of the screw rod 23 for driving the rotation of the screw rod 23, thereby realizing the movement and positioning of the workbench 2;

[0032] The cleaning assembly 4 includes a support frame 41 fixedly mounted on one side of the bottom end of the workbench 2, a servo motor 42 is fixedly mounted on the support frame 41, a positioning shaft 43 is fixedly connected to the output end of the servo motor 42, a rotating shaft 47 rotatably mounted on the workbench 2 is arranged above the positioning shaft 43, the positioning shaft 43 and the rotating shaft 47 are connected by a transmission member to ensure synchronous rotation of the two, a swing rod 49 is fixedly connected to the rotating shaft 47, a reset member is arranged on the swing rod 49, and is used to reset the swing rod 49 to its initial position after it swings, a connecting pipe 410 is installed at the other end of the swing rod 49, a row of air nozzles 411 are arranged on the connecting pipe 410 close to the side of the workbench 2, and one end of the connecting pipe 410 is connected to an air pump 4 through a hose. 12. The air pump 412 is fixedly installed on one side of the workbench 2 through a support plate. The servo motor 42 is turned on to drive the positioning shaft 43 to rotate. The positioning shaft 43 drives the rotating shaft 47, the swing rod 49, and the connecting pipe 410 to reciprocate through the transmission member and the reset member, so that the connecting pipe 410 can drive the air nozzle 411 to swing back and forth. In this way, the air nozzle 411 can change the jet angle during the swinging process. At the same time, the air pump 412 is turned on to provide an air source. The air source is transmitted to the air nozzle 411 through the connecting pipe 410 and finally ejected from the air nozzle 411. During the swinging process, the air nozzle 411 can effectively blow out the waste chips on the surface of the workbench 2 and in the rectangular groove 21, ensuring the cleaning effect, thereby improving the machining accuracy and work efficiency of the machine tool;

[0033] The transmission member includes a first half gear 44 and a second half gear 45 fixedly mounted on the positioning shaft 43. The two gears are closely matched and together constitute the core part of the transmission system. The outer side of the first half gear 44 is meshed with a gear frame 46 slidably mounted on the support frame 41. The gear frame 46 can flexibly slide laterally on the support frame 41 to adapt to different transmission requirements. The second half gear 45 is meshed with a driven gear 48 fixedly mounted on the rotating shaft 47. The driven gear 48 is closely combined with the rotating shaft 47 to ensure the stability and reliability of the transmission.

[0034] By turning on the servo motor 42, the positioning shaft 43 is driven to rotate, and the rotational power of the positioning shaft 43 is transmitted to the first half gear 44 and the second half gear 45, so that the two parts of the gears rotate synchronously. When the second half gear 45 rotates to mesh with the driven gear 48, the second half gear 45 can drive the driven gear 48 and the rotating shaft 47 to rotate, thereby realizing the coordinated work of the transmission system;

[0035] The rotating shaft 47 drives the swing rod 49, the connecting tube 410, and the air nozzle 411 to swing downward, so that the air nozzle 411 can effectively clean the waste chips on the surface of the workbench 2. When the second half gear 45 rotates and does not mesh with the driven gear 48, the reset member can drive the swing rod 49, the connecting tube 410, and the air nozzle 411 to reset upward, ensuring that the air nozzle 411 is always in a swinging state when spraying air. This swinging mechanism can better clean the waste chips on the surface of the workbench 2. The swinging air nozzle 411 can more comprehensively cover the surface of the workbench 2, ensuring that the waste chips are blown away more effectively.

[0036] Compared with the fixed-position air nozzle 411, the swinging air nozzle 411 can reduce the blind area of ​​cleaning and improve the overall cleaning efficiency. Since the air nozzle 411 can continuously change the air jet angle during the swinging process, it can more effectively blow away the waste chips attached to the surface or corners of the workbench 2. This dynamic cleaning method is more adaptable to waste chips of different shapes and sizes than static cleaning, thereby improving the cleaning quality.

[0037] The design of the reset member is equally ingenious, including a slide groove opened on the surface of the swing rod 49, in which a positioning rod 434 fixedly mounted on the support plate is slidably arranged, and the upper and lower ends of the positioning rod 434 are provided with fitting blocks 435 that fit with the surface of the swing rod 49, and the outer side of the fitting block 435 is provided with a third damping spring 436 that is sleeved on the positioning rod 434. When the servo motor 42, the positioning shaft 43, the second half gear 45, the driven gear 48, and the rotating shaft 47 drive the swing rod 49 to rotate downward, it can drive the fitting block 435 below to slide downward on the positioning rod 434 and compress the third damping spring 436 to provide a certain resistance for the swing rod 49. When the second half gear 45 is no longer meshed with the driven gear 48, driven by the elastic force of the third damping spring 436, the swing rod 49 can rotate upward and reset to its initial position, thereby ensuring the stable operation of the entire transmission system.

[0038] In the embodiment of the present invention, the required air source is provided by starting the air pump 412, and the air source is transmitted through the connecting pipe 410 and finally ejected through the air nozzle 411. During the swinging process of the air nozzle 411, it can effectively blow out the waste chips on the surface of the workbench 2 and in the rectangular groove 21, thereby ensuring the effect of the cleaning work. In order to achieve this process, it is necessary to start the servo motor 42 first, and the servo motor 42 drives the positioning shaft 43 to rotate. The rotation of the positioning shaft 43 will further drive the first half gear 44 and the second half gear 45 to rotate synchronously. When the second half gear 45 rotates to a position meshing with the driven gear 48, the second half gear 45 will drive the driven gear 48 and the rotating shaft 47 to rotate together. The rotation of the rotating shaft 47 will drive the swing rod 49, the connecting pipe 410 and the air nozzle 411 to swing downward, and compress the third damping spring 4 36. When the second half gear 45 is no longer engaged with the driven gear 48 during the rotation process, the elastic force of the third damping spring 436 will cause the swing rod 49 to rotate upward and reset. Through this reciprocating motion, the air nozzle 411 can always maintain a swinging state when spraying air, so as to more effectively clean the waste chips on the surface of the workbench 2. The swinging air nozzle 411 can cover the surface of the workbench 2 more comprehensively, ensuring that the waste chips are blown away more effectively. Compared with the air nozzle 411 in a fixed position, the swinging air nozzle 411 can significantly reduce the cleaning blind area, thereby improving the overall cleaning efficiency. Since the air nozzle 411 can continuously change the jet angle during the swinging process, it can more effectively blow away the waste chips attached to the surface or corners of the workbench 2. This dynamic cleaning method is more adaptable to waste chips of different shapes and sizes than static cleaning, thereby improving the cleaning quality.

[0039] Embodiment 2: Combination Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, on the basis of the first embodiment, a bidirectional gear 413 is rotatably connected in the middle of both sides of the workbench 2, and the upper and lower ends of the bidirectional gear 413 are respectively meshed and connected with the upper tooth plate 415 and the lower tooth plate 414, and the upper tooth plate 415 and the lower tooth plate 414 are set as symmetric centers to ensure their symmetry, one end of the lower tooth plate 414 is fixedly connected to the connecting rod 416, and the other end of the connecting rod 416 is fixedly connected to the tooth frame 46, and the two ends of the lower tooth plate 414 are respectively fixedly connected to the first slide plate 417, and the two ends of the upper tooth plate 415 are fixedly connected to the second slide plate 418, and the ends of the first slide plate 417 and the second slide plate 418 are slidably installed in the rectangular groove 21, and the top of the first slide plate 417 located on the outside is slidably connected to the first brush plate 419, and similarly, the top of the second slide plate 418 located on the outside is slidably connected to the second brush plate 420, and the first brush plate 419 and the second brush plate 420 are respectively located on both sides above the workbench 2;

[0040] When the servo motor 42 is started and drives the positioning shaft 43 and the first half gear 44 to rotate, the first half gear 44 will drive the gear frame 46 to move back and forth on the support frame 41, and the movement of the gear frame 46 will drive the lower gear plate 414 to move back and forth, thereby making the two-way gear 413 meshing with the lower gear plate 414 drive the upper gear plate 415 to move back and forth, and the movement of the upper gear plate 415 drives the second brush plate 420 to move back and forth on the surface of the workbench 2 through the second slide plate 418, and the lower gear plate 414 drives the first brush plate 419 to move back and forth on the surface of the workbench 2 through the first slide plate 417, so that the first brush plate 419 and the second brush plate 420 can move horizontally to clean the surface of the workbench 2;

[0041] The outer ends of the lower tooth plate 414 and the upper tooth plate 415 are both provided with control parts, which include a fixed plate 421 fixedly mounted on the second sliding plate 418, a row of knocking rods 423 are slidably connected to the fixed plate 421, the outer ends of the knocking rods 423 are fixedly connected to the connecting plate 424, and the inner ends are fixedly connected to the limit blocks 425, a first damping spring 426 sleeved on the knocking rods 423 is provided between the limit blocks 425 and the fixed plate 421, the surface of the connecting plate 424 is fixedly connected to the reciprocating plate 429, the surface of the reciprocating plate 429 is provided with a reciprocating groove, the inner end of the limit block 425 is fixedly connected to the vertical rod 427, the bottom end of the vertical rod 427 is fixedly connected to the guide rod 428, and the guide rod 428 is located at the lower tooth plate 414 The reciprocating plate 429 is slidably connected on the surface of the reciprocating plate 429. When the lower tooth plate 414 and the upper tooth plate 415 move back and forth, they can drive the vertical rod 427 and the guide rod 428 to move back and forth. When the guide rod 428 moves in the reciprocating groove, the connecting plate 424 cooperates with the knocking rod 423, the limit block 425 and the first damping spring 426 to push the connecting plate 424 to move back and forth. In this way, the connecting plate 424 drives the knocking rod 423 to knock the side wall of the workbench 2 back and forth, thereby assisting the first brush plate 419 and the second brush plate 420 in cleaning the workbench 2. Through the knocking action, the impact force on the side wall of the workbench 2 can be increased, which helps to remove stubborn stains and impurities attached to the surface of the workbench 2 or in the gaps, thereby improving the thoroughness and efficiency of cleaning;

[0042] The outer end of the connecting plate 424 is fixedly connected to the extension plate 432, and the inner end of the extension plate 432 is fixedly connected to the push rod 433. The position of the push rod 433 corresponds to the position of the first brush plate 419 and the second brush plate 420. One side of the first brush plate 419 and the second brush plate 420 is fixedly connected to the slide bar 430. The slide bar 430 on the first brush plate 419 is slidably installed on the first slide plate 417, and the slide bar 430 on the second brush plate 420 is slidably installed on the second slide plate 418. The slide bar 430 is sleeved with a second damping spring 431. When the connecting plate 424 moves back and forth, the connecting plate 424 can drive the extension plate 432 and the push rod 433 to reciprocate. When the push rod 433 moves back and forth, it can knock the first brush plate 419 and the second brush plate 420, so that the waste sticking on the first brush plate 419 and the second brush plate 420 can be knocked and vibrated. At the same time, when the first brush plate 419 and the second brush plate 420 are knocked, they will drive the sliding rod 430 to slide and compress the second damping spring 431. The second damping spring 431 is used for resetting the first brush plate 419 and the second brush plate 420, so that the first brush plate 419 and the second brush plate 420 can move back and forth. In this way, the first brush plate 419 and the second brush plate 420 can clean the surface of the workbench 2 longitudinally to ensure the cleanliness of the workbench 2.

[0043] In the embodiment of the present invention, when the servo motor 42 starts to operate, it drives the positioning shaft 43 and the first half gear 44 to rotate. As the first half gear 44 rotates, it drives the tooth frame 46 to move back and forth on the support frame 41. The movement of the tooth frame 46 further prompts the lower tooth plate 414 and the upper tooth plate 415 to move back and forth accordingly. When the lower tooth plate 414 and the upper tooth plate 415 are meshed with the two-way gear 413, they drive the two-way gear 413 to move together, thereby realizing the reciprocating motion of the upper tooth plate 415 and the lower tooth plate 414. This movement enables the lower tooth plate 414 to drive the first brush plate 419 to move horizontally on the surface of the workbench 2 through the first slide plate 417 to clean the surface. At the same time, the upper tooth plate 415 drives the second brush plate 420 to move horizontally on the surface of the workbench 2 through the second slide plate 418 to clean the surface. In this way, the first brush plate 419 and the second brush plate 420 can effectively move horizontally on the surface of the workbench 2.

[0044] When the lower tooth plate 414 and the upper tooth plate 415 move back and forth, they can also drive the vertical rod 427 and the guide rod 428 to move back and forth. During the reciprocating movement, the guide rod 428 will be located in the reciprocating groove of the reciprocating plate 429 and move. When the guide rod 428 moves in the reciprocating groove, the connecting plate 424 will cooperate with the knocking rod 423, the limit block 425 and the first damping spring 426 to push the connecting plate 424 to move back and forth. This reciprocating movement will cause the connecting plate 424 to drive the knocking rod 423 to knock the side wall of the workbench 2 back and forth. This knocking action helps to assist the first brush plate 419 and the second brush plate 420 in cleaning the workbench 2. By increasing the impact force on the side wall of the workbench 2, it can more effectively remove stubborn stains and impurities attached to the surface or gaps of the workbench 2, thereby improving the thoroughness and efficiency of cleaning.

[0045] When the connecting plate 424 moves back and forth, it can also drive the extension plate 432 and the push rod 433 to move back and forth. During the reciprocating movement, the push rod 433 will knock the first brush plate 419 and the second brush plate 420, so as to knock and vibrate the waste sticking on the first brush plate 419 and the second brush plate 420. When the first brush plate 419 and the second brush plate 420 are knocked, they will drive the sliding rod 430 to slide and compress the second damping spring 431. The function of the second damping spring 431 is to help the first brush plate 419 and the second brush plate 420 to reset and ensure that they can continue to move back and forth. In this way, the first brush plate 419 and the second brush plate 420 can clean the surface of the workbench 2 longitudinally to ensure that the cleanliness of the surface of the workbench 2 reaches the optimal state.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
