Description

Technical Field

[0001] The invention relates to the technical field related to vertical machining centers, and in particular to a medium-sized machining center with self-chip collection. Background Art

[0002] Machining centers are usually used in the processing of valve castings. For some high-precision valve castings, such as valves used in aerospace, precision chemical and other fields, they have extremely high requirements for dimensional accuracy, geometric tolerance and surface roughness. Machining centers can meet these requirements through precise programming and control. In addition, when mass-producing valve castings, the use of machining centers can realize automated processing by compiling standardized programs, improve production efficiency and reduce production costs. Moreover, machining centers can run continuously for a long time to ensure the stability of product quality.

[0003] During the machining process of valve castings in the machining center, chips will remain on the workbench. If they are not cleaned in time, the work surface will be untidy. When clamping the workpiece, extra time will be required to clean the table and wipe the positioning surface to ensure that the workpiece is installed accurately, which will increase the clamping time of the workpiece and reduce the machining efficiency.

[0004] In order to solve the above technical problems, a chip self-collecting medium-sized machining center waste collection and cleaning device (Announcement No. CN118386014B) has appeared in the prior art. It drives the screw to rotate through the cleaning flip control motor, and the screw drives the translation frame to reciprocate on the slide frame. With a number of driving gears, all cleaning heads rotate at the same time, thereby cleaning the surface of the processing platform. However, the defects are as follows:

[0005] 1. During the cleaning operation, the translation frame moves back and forth on the surface of the processing platform. Workers need to wait for the cleaning mechanism to complete the action before they can clamp the workpiece on the processing platform, which affects production efficiency;

[0006] 2. The lower end of each cleaning head is radial, which cannot be well adapted to the mounting groove on the surface of the processing platform. The chips remaining in the mounting groove will affect the installation of the workpiece, and there is also the defect that the chips fly around and are difficult to collect during the cleaning process. Summary of the invention

[0007] The present invention aims to solve one of the technical problems existing in the prior art.

[0040] The machining center provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0041] Embodiment 1:

[0042] like Figures 1 to 12 As shown, the embodiment of the present application provides a medium-sized machining center with chip self-collection, including a chassis 1, a work table 2 and a cleaning mechanism 3, wherein the top of the chassis 1 is open, and the work table 2 is rotatably mounted on the top of the inner cavity of the chassis 1 through a rotating shaft 41, and the rotating shaft 41 is driven by a flip control motor 42, and telescopic shells 43 are sleeved on both ends of the work table 2, and a plurality of mounting grooves 44 are provided on the upper and lower side surfaces of each telescopic shell 43, and a semicircular slide groove 45 is provided on the side wall of the inner cavity of the chassis 1, and a starting section 46 and an end section 47 extending horizontally outward are respectively provided at both ends of the semicircular slide groove 45, and a slider 48 is provided on the side wall of one of the telescopic shells 43, and the slider 48 is slidably matched with the semicircular slide groove 45, and a transmission structure 5 connected to the rotating shaft 41 is provided in the inner cavity of the work table 2, and the cleaning mechanism 3 is arranged in the inner cavity of the chassis 1;

[0043] Among them, the transmission structure 5 is used to cooperate with the semicircular groove 45 and the slider 48 when the shaft 41 rotates clockwise / counterclockwise, to control the outer ends of a pair of telescopic shells 43 to first detach from the inner cavity side wall of the chassis 1, then rotate 180° with the work table 2, and then the outer ends are pressed against the inner cavity side wall of the chassis 1.

[0044] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when a pair of telescopic shells 43 need to be cleaned toward the outside, the flip control motor 42 is operated, the rotating shaft 41 rotates clockwise / counterclockwise, and the pair of telescopic shells 43 are controlled to approach each other through the transmission structure 5 until the slider 48 enters the semicircular slide groove 45 from the starting section 46 / the final section 47. At this time, the slider 48 is pressed against the inner peripheral wall of the semicircular slide groove 45, and the flip control motor 42 continues to operate, driving the work table 2 and each telescopic shell 43 to rotate 180° clockwise / counterclockwise until the slider 4 8 is pressed against the top surface of the terminal section 47 / initial section 46. At this time, the side of each telescopic shell 43 that needs to be cleaned is flipped into the inner cavity of the chassis 1, and the side originally facing the inner cavity of the chassis 1 is flipped to face outward, and then the flip control motor 42 continues to run, and the transmission structure 5 controls a pair of telescopic shells 43 to separate from each other until the outer ends of a pair of telescopic shells 43 are pressed against the side walls corresponding to the inner cavity of the chassis 1, and the slider 48 also slides to the inner end of the terminal section 47 / initial section 46, and then the cleaning mechanism 3 is activated to clean the inner side surface of a pair of telescopic shells 43 and the corresponding mounting grooves 44.

[0045] Embodiment 2:

[0046] like Figures 2 to 9As shown, in the present embodiment, in addition to the structural features of the aforementioned embodiments, the transmission structure 5 includes an I-shaped cavity, which includes an upper transverse groove 51 and a lower transverse groove 52 that pass through the left and right sides, and a connecting groove 53 that connects the middle parts of the upper transverse groove 51 and the lower transverse groove 52. A gear 54 is rotatably installed in the connecting cavity, and the rotating shaft 41 is fixedly connected to the gear 54 and is rotatably connected to the work table 2. Telescopic connecting pairs 55 are installed in the upper transverse groove 51 and the lower transverse groove 52. Each telescopic connecting pair 55 is simultaneously meshed with the gear 54 by moving the rack 551. Different ends of each telescopic connecting pair 55 are fixed with T-shaped plates 56, and each T-shaped plate 56 is slidably penetrated with a T-shaped slide bar 57. One end of each T-shaped slide bar 57 is fixedly connected to the inner end of the adjacent telescopic shell 43, and a supporting spring 58 is provided between the other end and the adjacent T-shaped plate 56.

[0047] Furthermore, the telescopic connection pair 55 includes a pair of L frames 552 that embrace each other. The pair of L frames 552 each include a baffle 5521 that is fixed to the movable rack 551 / T-shaped plate 56 through a connecting rod 5522. A supporting spring 5523 is provided between the pair of baffles 5521.

[0048] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the slider 48 is located at the inner end of the starting section 46, the rotating shaft 41 rotates clockwise, and the gear 54 is meshed with each movable rack 551, driving a pair of telescopic connecting pairs 55 to move relative to each other, so that a pair of T-shaped plates 56 approach each other, and each supporting spring 58 moves together with the corresponding T-shaped plate 56, pushing the corresponding T-shaped slide rods 57 to approach the rotating shaft 41, and a pair of telescopic shells 43 approach each other, and the outer ends are out of contact with the side wall of the inner cavity of the chassis 1, until Until each T-shaped plate 56 is tightly pressed against the outer wall of the table, each T-shaped slide bar 57 enters the upper transverse groove 51 and the lower transverse groove 52 respectively, the end of the movable rack 551 away from the corresponding T-shaped plate 56 is respectively pressed against the free end of each T-shaped slide bar 57, and the slider 48 enters the semi-circular groove, the center of the semi-circular groove is located on the axis of the rotating shaft 41, and at this time, the supporting force provided by each support spring 58 to the corresponding L frame 552 is greater than the friction force of the slider 48 sliding in the semi-circular groove, so that each movable rack 551 no longer moves relative to each other. Instead, the pair of telescopic shells 43 are kept in a closed state during this process until the work table 2 and the pair of telescopic shells 43 are turned over 180 degrees, and the slider 48 abuts against the top surface of the terminal section 47. At this time, the slider 48 cannot continue to rotate about the central axis of the rotating shaft 41. The continuously rotating gear 54 can only drive the pair of moving racks 551 to continue to move relative to each other, and the pair of baffles 5521 in each telescopic connection pair 55 approach each other, and each supporting spring 5523 Deformation occurs, each T-shaped plate 56 maintains contact with the side wall of the work surface 2, and each movable rack 551 moves toward the T-shaped plate 56 connected to another telescopic connection pair 55, pushing each T-shaped slide bar 57 to be ejected out of the upper horizontal groove 51 / lower horizontal groove 52, and each supporting spring 58 is compressed to store elastic potential energy, a pair of telescopic shells 43 are separated, and the slider 48 slides toward the inner end of the terminal section 47 until the slider 48 is tightly pressed against the inner end of the terminal section 47, and the outer ends of a pair of telescopic shells 43 are also tightly pressed against the side wall of the inner cavity of the chassis 1.

[0049] When the slider 48 is located at the starting, ending and ending sections 47, the rotating shaft 41 rotates counterclockwise, and through the meshing of the gear 54 and each movable rack 551, a pair of telescopic connecting pairs 55 are driven to move toward the corresponding T-shaped plate 56, and the supporting spring 2 5523 in each telescopic connecting pair 55 is deformed to release elastic potential energy, thereby pushing each pair of baffles 5521 to separate from each other, each T-shaped plate 56 to maintain contact with the side wall of the work table 2, and each movable rack 551 to move away from the T-shaped plate 56 connected to another telescopic connecting pair 55, and each supporting spring 1 58 releases elastic potential energy, pushing each T-shaped slide bar 57 to move into the upper horizontal groove 51 / lower horizontal groove 52, a pair of telescopic shells 43 are closed, and the slider 48 enters the semicircular arc groove. At this time, the supporting force provided by each supporting spring 1 58 to the corresponding L frame 552 is greater than the friction force of the slider 48 sliding in the semicircular arc groove, so that each movable rack 551 no longer moves relatively but moves with the gear 54. The pair of telescopic shells 43 are kept in a closed state during the process until the working table 2 and the pair of telescopic shells 43 are turned over 180°, and the slider 48 abuts against the top surface of the starting section 46. At this time, the slider 48 cannot continue to rotate about the central axis of the rotating shaft 41, and the continuously rotating gear 54 can only drive a pair of movable racks 551 to continue to move relative to each other. The pair of baffles 5521 in each telescopic connection pair 55 remain separated under the support of each supporting spring 2 5523, pushing a pair of T-shaped plates 56 to separate from each other and break away from the fit with the side wall of the working table 2. Each T-shaped slide bar 57 is separated from the corresponding upper transverse groove 51 / lower transverse groove 52, and each T-shaped plate 56 abuts against the inner end surface of the corresponding telescopic shell 43 and pushes the pair of telescopic shells 43 to separate, and the slider 48 slides toward the inner end of the starting section 46 until the slider 48 abuts against the inner end of the starting section 46, and the outer ends of a pair of telescopic shells 43 also abut against the side wall of the inner cavity of the chassis 1.

When the transmission gear shaft 82 rotates, the reciprocating frame 34 is driven by the reciprocating connection pair 84 to perform a reciprocating motion parallel to the axis of the rotating shaft 41 relative to the sliding table 33.

[0056] Furthermore, the reciprocating connection pair 84 includes a loop groove 841 arranged on the peripheral wall in the middle of the linkage gear shaft 81. The loop groove 841 is elliptical, and its two ends extend to the two ends of the linkage gear shaft 81 respectively. A connecting plate 842 is fixed to the bottom of the reciprocating frame 34, and the connecting plate 842 is sleeved in the middle of the linkage gear shaft 81 through a sliding hole 843. A transmission block that slides with the loop groove 841 is provided on the inner wall of the sliding hole 843.

[0057] Furthermore, the axes of the linkage gear shafts 81 and the transmission gear shafts 82 are parallel to the axis of the rotating shaft 41 , and the axis of the transmission gear shaft 83 is perpendicular to the axis of the rotating shaft 41 .

[0058] Furthermore, both ends of the transmission gear shaft 83 are meshed with the corresponding fixed rack 36 through the first spur gear 831, and second bevel gears 832 are fixed at both ends. One end of each linkage gear shaft 81 is meshed with each second bevel gear 832 through the third bevel gear 811.

[0059] Furthermore, the transmission gear pair 85 includes a bevel gear shaft 851 and a spur gear shaft 852, both of which are rotatably mounted in the reciprocating frame 34. The bevel gear shaft 851 is meshed with the transmission gear shaft 82 through the first bevel gear 822 and is meshed with the spur gear shaft 852 through the spur gear pair 853. The spur gear shaft 852 is fixedly connected to the end of the brush roller 35.

[0060] Furthermore, the transmission gear shaft 82 includes a spur column 821 and a first bevel gear 822 , and the spur column 821 is meshed with the linkage gear shaft 81 through a second spur gear 823 for transmission.

[0061] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the side walls of a pair of telescopic shells 43 located in the inner cavity of the chassis 1 are cleaned, the sliding drive motor 311 runs, the screw rod 312 rotates, and cooperates with the screw hole 313 to drive the chip pusher plate 32 to move toward the chip discharge port 7 until the side wall of the chip pusher plate 32 coincides with the chip discharge port 7, and then the sliding drive motor 311 is reversed, and through the cooperation of the screw rod 312 and the screw hole 313, the chip pusher plate 32 and each sliding table 33 are driven away from the chip discharge port 7 until each reciprocating frame 34 is detached from the bottom of each telescopic shell 43. In this process, the transmission gear shaft 83 is meshed with the fixed rack 36 through the first spur gear 831. When the chip pusher plate 32 and each sliding table 33 move along the axis of the rotating shaft 41, the transmission gear shaft 83 rotates, and at the same time, a pair of second bevel gears 832 rotate, and through a pair of third bevel gears 811 The pair of linkage gear shafts 81 are driven to rotate. When the pair of linkage gear shafts 81 rotate, the loop groove 841 provided on the peripheral wall thereof rotates together, so that the corresponding transmission block reciprocates between the side of the loop groove 841 close to the second bevel gear 832 and the side of the loop groove 841 away from the second bevel gear 832. The connecting plate 842 and the reciprocating frame 34 reciprocate along the axis of the linkage gear shaft 81. During the movement of the transmission gear shaft 82 along with the reciprocating frame 34, the spur column 821 can keep in contact with the second spur gear 823. The rotating linkage gear shaft 81 meshes with the spur column 821 through the second spur gear 823, driving the transmission gear shaft 82 to rotate. Then the first bevel gear 822 drives the bevel gear shaft 851 to rotate.
