DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0038] like Figure 1-Figure 4 As shown, an automatic drilling processing device for plate parts of engineering machinery proposed in one embodiment of the present application includes:

[0039] The three-axis mobile machine base 1 includes a base 101, on which a screw rod 102 is rotatably installed, and a U-shaped moving frame 103 slidably installed in the base 101 is threadedly sleeved on the screw rod 102, and an n-shaped flip frame 104 is hinged on the upper end of the U-shaped moving frame 103, and a screw rod 2 105 is rotatably installed in the n-shaped flip frame 104, and a moving seat 106 slidably installed in the n-shaped flip frame 104 is threadedly sleeved on the screw rod 2 105, and a vertically arranged screw rod 3 107 is rotatably installed in the moving seat 106, and a screw rod 3 107 is threaded on the screw rod 3 A movable block 108 is sleeved and slidably installed in the movable seat 106, and a drilling machine 109 is fixedly connected to the movable block 108. It should be noted that the screw rod 102 and the screw rod 2 105 are arranged vertically, and the screw rod 2 105 and the screw rod 3 107 are arranged vertically, and the screw rod 102, the screw rod 2 105 and the screw rod 3 107 are all rotated by a motor to control the spatial orientation of the movable block 108. The position of the drilling hole can be automatically adjusted without manual handling of the plate parts, thereby increasing the convenience of the device;

[0040] The adjustable bearing frame 2 includes a plurality of fixed blocks 201 fixedly connected to both ends of the base 101, and a slide rail 202 is connected between the fixed blocks 201 facing each other, and a spacing groove 203 is constructed between two adjacent fixed blocks 201. A plurality of support blocks 204 are slidably installed on the slide rail 202 along its length direction. The traditional integral structure working platform is only constructed with a single through hole, and the position of the plate component needs to be changed after the previous drilling is completed to adjust the drilling position to prevent the drilling machine 109 from penetrating the working platform. In the present application, only different support blocks 204 need to be moved to the position of the plate component that does not need drilling in advance for support. In this way, there is no need to change the position of the plate during processing, and drilling operations can be continuously performed at different positions of the plate component, which increases convenience and improves processing efficiency.

[0041] The clamping member 3 comprises two oppositely arranged transverse plates 301, the bottom of which is constructed with a plurality of rectangular blocks 302 slidably mounted in the spacing grooves 203, an adjusting sleeve 303 rotatably mounted in the rectangular block 302, a solenoid 304 slidably mounted in the adjusting sleeve 303 through the inner thread, the solenoid 304 having a clamping column 305 hinged at one end and a pressurizing tube 306 connected at the other end, an electromagnetic control valve is installed between the pressurizing tube 306 and the plurality of solenoids 304 for controlling the flow direction of the airflow, so as to separately pressurize one or more of the solenoids 304, and when the pressure is sufficient, the clamping column 305 can be pushed to turn upward by ninety degrees, so as to facilitate the contact clamping of the edge of the plate, it should be noted that the two transverse plates 301 are arranged oppositely along the length direction of the base 101, and the rectangular block 302 at the bottom thereof is arranged at an interval from the support block 204 (i.e. one support block 204 is adjacent to one rectangular block 302);

[0042] The synchronous pusher 4 is installed on the base 101 and is used to drive the two horizontal plates 301 to move synchronously relative to each other. When drilling is required for plate parts, the adjustment sleeve 303 can be rotated to engage with the screw tube 304 to adjust the position between the screw tube 304 and the rectangular block 302, so that the clamping column 305 at the end of the screw tube 304 can abut against the edge of the irregular plate parts (such as the triangular shell plate of the engineering machinery), and two of the screw tubes 304 can be extended to abut against the hypotenuse of the triangular plate, and then the synchronous pusher 4 can be used to adjust the position of the screw tube 304 and the rectangular block 302. The moving piece 4 moves the two horizontal plates 301 relative to each other, so that the edges of the plate parts can be tightly clamped by the clamping columns 305 at the ends of the multiple screw tubes 304, so as to maintain the stability of the drilling. It should be noted that the clamping columns 305 are initially located on the same axis as the screw tubes 304, and will not affect the flat placement of the plate above the support block 204. When it is necessary to clamp the edges of irregular plates, the pressure tube 306 can be used to pressurize the clamping columns 305 that are needed so that they can be flipped. The automatic operation improves the convenience of the device.

[0043] like Figure 1-Figure 2 As shown, in some embodiments, connecting rings 1041 are constructed at both ends of the bottom of the n-type flip frame 104, and hinged columns 1031 rotatably installed in the connecting rings 1041 are constructed at both ends of the upper side of the U-shaped moving frame 103. A cylinder push rod 1042 is hinged between the connecting ring 1041 and the U-shaped moving frame 103. The n-type flip frame 104 can be rotatably installed on the U-shaped moving frame 103 using the connecting ring 1041 and the hinged column 1031. It should be noted that one end of the cylinder push rod 1042 is hinged to one side of the connecting ring 1041 horizontally, and the n-type flip frame 104 is constructed as a movable groove located on the other side of the connecting ring 1041 horizontally to provide a flippable range of the n-type flip frame 104. When the device is in operation, it only needs to use the telescopic operation of the cylinder push rod 1042 to adjust the relative angle between the n-type flip frame 104 as a whole and the U-shaped moving frame 103, so as to change the direction of the drilling rig 109, so as to drill inclined holes in the plate and improve the flexibility of the device.

[0044] like Figure 3As shown, in some embodiments, a horizontal plug-in slot 2041 is constructed on the top of the support block 204, and a magnet block 2042 is detachably inserted in the horizontal plug-in slot 2041. A stepped hole 2043 is constructed on the top of the magnet block 2042, and a positioning bolt 2044 with a thread passing through the support block 204 is movably inserted in the stepped hole 2043. It should be noted that the support block 204 is made of aluminum alloy as a whole, and the horizontal plug-in slot 2041 is set on the upper surface of the support block 204 and is connected to its two end sides. The magnet block 2042 can be inserted therein from the horizontal direction, and the upper surface of the magnet block 2042 is exposed to adsorb the iron plate material, thereby increasing the stability of the device clamping the iron plate. The positioning bolt 2044 is used to resist the slide rail 202, so as to facilitate fixing after the support block 204 is adjusted in position, thereby increasing the stability of the structure.

[0045] like Figure 5-Figure 6 As shown, in some embodiments, the rectangular block 302 is horizontally constructed with a rotating groove 3021 at one end and a sliding groove 3022 connected to the rotating groove 3021 at the other end, and the screw tube 304 is constructed with two sliding planes 3041 that are relatively arranged and fit with the inner wall of the sliding groove 3022, and the adjusting sleeve 303 is rotatably installed in the rotating groove 3021. It should be noted that the width of the sliding planes 3041 on the upper and lower sides of the screw tube 304 is much smaller than the diameter of the screw tube 304, and therefore does not affect the threaded fit of the screw tube 304 and the diameter of the adjusting sleeve 303, but can be slidably fitted with the sliding groove 3022, thereby limiting the rotation of the screw tube 304, so that it can smoothly realize threaded fit with the adjusting sleeve 303, and personnel adjust the extension distance of different screw tubes 304 to adapt to the clamping of the edges of plates of different shapes, thereby improving the flexibility of the device.

[0046] like Figure 6-Figure 7 As shown, in some embodiments, an arc groove 3042 is configured at one end of the spiral tube 304, and the clamping column 305 includes a semicircular block 3051 hinged at the center of the arc groove 3042, and an air inlet groove 3052 is configured on the upper side of the end of the semicircular block 3051 facing the inside of the spiral tube 304, and a return spring 3053 is connected between the air inlet groove 3052 and the top of the spiral tube 304, and an air jet column 3054 is configured at one end of the semicircular block 3051 facing the outside of the spiral tube 304. It should be noted that the shape of the arc groove 3042 is a quarter-fan-shaped column structure, and The semicircular block 3051 is a semi-cylindrical structure. When the spiral tube 304 takes in air, the gas can enter the air inlet groove 3052 through the gap between the upper side of the semicircular block 3051 and the inner wall of the spiral tube 304, thereby squeezing the semicircular block 3051 to flip around the hinge point until it is flipped ninety degrees and hits the edge of the arc groove 3042 for limiting. At this time, the air jet column 3054 is in a vertical state, which can effectively hit the edge of the plate component and use air pressure to flip it without manual flipping one by one, thereby increasing the convenience and automation of the device.

[0047] like Figure 7 As shown, in some embodiments, the jet column 3054 includes a column tube 30541 constructed on the semicircular block 3051 and connected to the air inlet groove 3052, and a plurality of clamping rings 30542 are arrayed along the length direction of the column tube 30541, and the clamping ring 30542 is constructed with a jet hole 30543 connected to the interior thereof. It should be noted that the semicircular block 3051 is constructed with an air vent connected to the air inlet groove 3052 and the column tube 30541, and the air vent has a small diameter. When the air pressure is sufficient, the column tube 30541 can be pushed to flip first, and then the blowing can be continued. The clamping ring 30542 is used to increase the friction on the corners of the plate and improve the clamping stability. The jet holes 30543 on the two relative column tubes 30541 can blow toward the upper surface of the plate at the same time to prevent drilling debris from splashing out of the equipment, thereby increasing safety.

[0048] like Figure 8 As shown, in some embodiments, a suction component 5 is also included, and the suction component 5 includes an inclined bucket frame 501 fixedly connected to the bottom of the movable seat 106, the bottom of the inclined bucket frame 501 is inclined toward the drilling rig 109 and the top is configured with an L-shaped drop pipe 502, the side of the L-shaped drop pipe 502 is connected to an exhaust fan 503 and the bottom is connected to a collecting bag 504, and a filter sheet 505 is arranged between the exhaust fan 503 and the L-shaped drop pipe 502. The suction component 5 can cooperate with the blowing of the column tube 30541 to realize the suction and collection of debris, further reduce the scattering of debris, and improve safety.

It should be noted that the driving motor 40 5 is not only the driving force of the screw rod 102, but also the driving force for the movement of the horizontal plate 301. When only the screw rod 102 needs to rotate, the switching member 6 can be used to connect to the screw rod 102 to adjust the position of the U-shaped moving frame 103. When the clamping column 305 contacts the edge of the plate, the switching member 6 can be used to connect the driving motor 405 and the auxiliary shaft 403, so that the driving motor 405 drives the two adjusting screw rods 401 to rotate at the same time through the auxiliary shaft 403, so that the two horizontal plates 301 can move relative to each other, so as to clamp the two sides of the plate tightly and improve the stability of the clamping. The clamped plate can also be loosened and replaced with a plate of the same shape to be clamped in between, thereby increasing the flexibility of the device.

When the driving motor 405 drives the screw rod 102 to rotate, the polygonal plug rod 602 is in a state of being inserted into the end of the screw rod 102. At this time, the polygonal expansion block 603 is outside the transmission wheel 604, so it can only drive the screw rod 102 to rotate, and the pushing member 7 can push the polygonal slide bar 601 to move, so that the polygonal plug rod 602 is separated from the screw rod 102, and the polygonal expansion block 603 is inserted into the transmission wheel 604 to disconnect from the screw rod 102 and realize the connection with the transmission wheel 604, so as to control the rotation of the auxiliary shaft 403 through the pulley transmission, and realize the relative movement of the cross plate 301, without the need for additional motor drive, saving electricity and equipment costs.
