Description

Technical Field

[0001] This invention relates to equipment for processing ship parts, and more particularly to a blank contour milling equipment and its operating method for a propeller blade production line. Background Technology

[0002] A propeller is a device that uses blades to rotate in air or water, converting the rotational power of an engine into propulsion. It can have two or more blades connected to a hub. The blades are important parts of the propeller, and their machining quality directly affects the propeller's performance.

[0003] The machining of propeller blades is highly complex, typically involving multiple processes, including milling the blank contour, chamfering the edges, and stamping. Currently, each process is completed independently, resulting in low automation and significant machining errors. Furthermore, existing technologies mostly employ CNC machine tools for milling the blank contour, requiring clamping the blank for each part, which is cumbersome and hinders production line efficiency. In addition, existing blank contour milling devices generally rely on manual loading or robotic arms for loading, which are complex and costly.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0015] Preferably, the conveying component includes four support legs distributed at the four corners, a U-shaped support plate located on the four support legs, a lead screw located at the middle position of the top surface of the U-shaped support plate via a bearing with a seat, a motor located on the top surface of the U-shaped support plate with its output shaft connected to the lead screw, a guide rail located on the top surface of the U-shaped support plate and arranged parallel to the lead screw, a slider that can slide back and forth along the guide rail, a drive plate fixedly connected to the slider, and an electromagnetic chuck located on the drive plate for holding the blank.

[0016] The present invention discloses an operation method for a blank contour milling equipment for a propeller blade production line, comprising the following steps:

[0017] The output shaft of motor No. 4 rotates, driving drive plate No. 4 and the electromagnetic chuck mounted on it to move along guide rail No. 4, moving drive plate No. 4 and the electromagnetic chuck mounted on it to the left end of the conveying component; the second electromagnetic push rod of the two sets of clamping assemblies on both sides of the blank bin is energized, the electromagnetic rod of the second electromagnetic push rod extends, driving the transverse clamping bar to move, the transverse clamping bar passes through the clamping hole of the blank bin, clamping the second blank from bottom to top placed in the blank bin; the first electromagnetic push rod is energized, the electromagnetic rod of the first electromagnetic push rod extends, lifting the two sets of clamping assemblies, thereby moving the second and above blanks from bottom to top placed in the blank bin upwards, creating a gap between the bottom blank and the second blank from bottom to top placed in the blank bin;

[0018] The piston rod of the second double-rod cylinder extends, causing the second bearing plate to move downwards; this pushes the bottom blank in the blank storage box onto the electromagnetic chuck of the conveying component, and the L-shaped positioning plate achieves positioning of the blank in one direction; the second electromagnetic push rod is de-energized, the electromagnetic rod of the second electromagnetic push rod retracts, the transverse clamping bar retracts from the clamping hole of the blank storage box, and the blank placed in the blank storage box moves downwards under its own gravity and falls onto the first table; the first electromagnetic push rod is de-energized, the electromagnetic rod of the first electromagnetic push rod retracts, and the two sets of clamping assemblies move downwards and return to their initial positions;

[0019] The second motor starts, causing the two T-shaped positioning plates on the left and right to close, thus positioning the blank in another direction; the electromagnetic chuck is energized, fixing the positioned blank; the second motor rotates in the opposite direction, causing the two T-shaped positioning plates on the left and right to open; the piston rod of the second double-rod cylinder retracts, causing the second bearing plate to move up and return to its initial position.

[0020] The output shaft of motor No. 4 rotates, driving the No. 4 drive plate, the electromagnetic chuck mounted on it, and the blank adsorbed on the electromagnetic chuck to move along the No. 4 guide rail until they are directly below the peripheral milling component. When the output shaft of the No. 3 transverse motor rotates, it drives the No. 3 transverse drive plate to move along the No. 3 transverse guide rail, forming the transverse feed motion of the peripheral milling component. When the output shaft of the No. 3 longitudinal motor rotates, it drives the No. 3 longitudinal drive plate to move along the No. 3 longitudinal guide rail, forming the longitudinal feed motion of the peripheral milling component. The No. 3 milling head mills the blank around its perimeter through interpolation, processing it into a semi-finished product. The output shaft of motor No. 4 rotates, driving the No. 4 drive plate, the electromagnetic chuck mounted on it, and the semi-finished product adsorbed on the electromagnetic chuck to move along the No. 4 guide rail until they are at the right end of the conveying component, completing the processing.

[0044] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0045] like Figure 1 As shown, the blank contour milling equipment for propeller blade production line in this invention includes a blank supply component 1, a blank positioning component 2, a peripheral milling component 3, and a conveying component 4. The conveying component 4 is arranged in a straight line, and the blank supply component 1 is placed in front of the conveying component 4, with both arranged in a straight line. The blank positioning component 2 and the peripheral milling component 3 are arranged in a straight line across the conveying component 4. The blank supply component 1 pushes the blank 5 onto the electromagnetic chuck 405 of the conveying component 4. After the blank positioning component 2 positions the blank 5 on the electromagnetic chuck 405, the conveying component 4 moves the blank 5 directly below the peripheral milling component 3. The peripheral milling component 3 mills the four sides of the blank 5 to form a semi-finished product 6.

[0046] like Figure 2 As shown, the blank supply component 1 includes a first table 11, clamping components 12, and a blank storage box 13. The blank storage box 13 is placed at one end of the top surface of the first table 11, and two sets of clamping components 12 are respectively placed on both sides of the blank storage box 13.

[0047] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first table 11 includes a first tabletop 111, a cover plate 112, non-powered rollers 113, a first electromagnetic push rod 114, and a first support leg 115. Several first support legs 115 are mounted on the bottom surface of the first tabletop 111, forming the overall support frame of the first table 11. One end of the first tabletop 111 has a recessed hole, and semi-circular stepped holes are machined on both sides of the recessed hole. Several non-powered rollers 113 are placed in a linear array in the semi-circular stepped holes on both sides of the recessed hole. The cover plate 112 has semi-circular stepped holes 118. Two cover plates are installed above both ends of the several non-powered rollers 113, thus reliably installing the non-powered rollers 113 in the recessed hole at one end of the first tabletop 111. Four first electromagnetic push rods 114 are mounted in a linear array on the bottom surface of the first tabletop 111, with their electromagnetic rods passing through the first electromagnetic push rod holes 117 on both sides of the recessed hole at one end of the first tabletop 111.

[0048] like Figure 7 As shown, the clamping assembly 12 includes a vertical clamping block 121, a second electromagnetic push rod 122, and a horizontal clamping bar 123. A horizontal guide post 125 is machined on one side of the horizontal clamping bar 123, a vertical guide post 124 is machined on the bottom surface of the vertical clamping block 121, and a horizontal guide hole and an electromagnetic push rod mounting groove are machined on the side of the vertical clamping block 121. The horizontal guide post 125 of the horizontal clamping bar 123 is inserted into the horizontal guide hole on the side of the vertical clamping block 121, and the second electromagnetic push rod 122 is installed in the electromagnetic push rod mounting groove on the side of the vertical clamping block 121. The end of the electromagnetic rod of the second electromagnetic push rod 122 is fixedly connected to the side of the horizontal clamping bar 123. The vertical guide post 121.1 of the vertical clamping block 121 of the clamping assembly 12 is inserted into the first guide hole 116 of the first platform 111. The bottom surface of the vertical guide post of the vertical clamping block 121 of the clamping assembly 12 is fixedly connected to the end of the first electromagnetic push rod 114 electromagnetic rod installed on the bottom surface of the first platform 111, thereby installing the clamping assembly on the first platform 111.

[0049] like Figure 8As shown, the blank storage box 13 has a square structure, and its cross-sectional area is the same as that of the blank 5. The middle compartment 131 is used to place the blank 5. The left and right sides of the blank storage box 13 have observation holes 132 for observing the storage status of the blank 5 in the middle compartment 131. The bottom of the blank storage box 13 has a discharge hole 133, and the height of the discharge hole 133 is slightly greater than the thickness of a blank 5. The front and rear sides of the blank storage box 13 have clamping holes 134. The lower edge of the clamping hole 134 is slightly greater than the thickness of a blank 5, and the height of the clamping hole 134 is greater than the height of the horizontal clamping bar 123. There is a gap between the upper edge of the clamping hole 134 and the upper surface of the horizontal clamping bar 123 so that the horizontal clamping bar 123 of the clamping assembly 12 can pass through the clamping hole 134, and at the same time, it is convenient for the clamping assembly 12 to move upward.

[0050] The working process of blank supply component 1 is as follows:

[0051] 1) The second electromagnetic push rod 122 of the two sets of clamping components 12 placed on both sides of the blank storage box 13 is energized. The electromagnetic rod of the second electromagnetic push rod 122 extends and drives the transverse clamping bar 123 to move. The transverse clamping bar 123 passes through the clamping hole 134 of the blank storage box 13 and clamps the second blank 5 placed in the middle compartment 131 of the blank storage box 13 from bottom to top.

[0052] 2) The four electromagnetic push rods 114 installed in a linear array on the bottom surface of the first platform 111 are energized. The electromagnetic rods of the first electromagnetic push rods 114 extend out and pass through the first electromagnetic push rod holes 117 on both sides of the concave hole at one end of the first platform 111, lifting up the two sets of clamping assemblies 12, thereby moving the second and above blanks 5 placed in the middle compartment 131 of the blank storage box 13 from the bottom up upwards, creating a gap between the bottom blank 5 placed in the middle compartment 131 of the blank storage box 13 and the second blank 5 from the bottom up.

[0053] 3) The piston rod of the cylinder (not shown in the figure) installed on one side of the first table 111 extends and pushes the bottom blank 5 placed in the middle compartment 131 of the blank box 13 to the electromagnetic chuck 405 of the conveying component 4.

[0054] 4) The piston rod of the cylinder (not shown in the figure) installed on one side of platform 111 retracts and returns to its initial state;

[0055] 5) The second electromagnetic push rod 122 of the two sets of clamping components 12 placed on both sides of the blank storage box 13 is de-energized, the electromagnetic rod of the second electromagnetic push rod 122 retracts, the transverse clamping bar 123 retracts from the clamping hole 134 of the blank storage box 13, and the clamping on the second blank 5 placed from bottom to top in the middle compartment 131 of the blank storage box 13 is released. The second and above blanks 5 placed from bottom to top in the middle compartment 131 of the blank storage box 13 move down under their own gravity and fall on the first table 111.

[0056] 6) When the four No. 1 electromagnetic push rods 114, which are installed in a linear array on the bottom surface of No. 1 platform 111, are de-energized, the electromagnetic push rods 114 retract, and the two sets of clamping assemblies 12 move down and return to their initial positions.

[0057] like Figure 9 and Figure 10 As shown, the blank positioning component 2 includes a second support leg 201, a second guide rod with flange 202, a second linear bearing 203, a second top plate 204, a second double-rod cylinder 205, a second bearing plate 206, a second guide rod 207, a T-shaped positioning plate 208, a second motor 209, a second lead screw 210, and an L-shaped positioning plate 211.

[0058] like Figure 9 As shown, several No. 2 support legs 201 are installed on the bottom surface of the No. 2 top plate 204, forming the overall support frame of the blank positioning component 2. Four No. 2 linear bearings 203 are installed in a linear array at the four corners of the No. 2 top plate 204. No. 2 flanged guide rods 202, which are installed in a linear array at the four corners of the No. 2 bearing plate 206, pass through the four No. 2 linear bearings 203 installed in a linear array at the four corners of the No. 2 top plate 204. No. 2 double-rod cylinders 205 are fixedly installed on the bottom surface of the No. 2 top plate 204. The end of the piston rod of the No. 2 double-rod cylinder 205 is fixedly connected to the top surface of the No. 2 bearing plate 206. When the piston rod of the No. 2 double-rod cylinder 205 retracts or extends, it drives the No. 2 bearing plate 206 to move upward or downward.

[0059] like Figure 10As shown, the left section of the second lead screw 210 has a left-hand thread, and the right section has a right-hand thread. The second lead screw 210 is mounted in the middle of the bottom surface of the second bearing plate 206 via a bearing with a mounting seat. The second motor 209 is mounted at one end of the bottom surface of the second bearing plate 206 via a motor mounting bracket. The output shaft of the second motor 209 is connected to the second lead screw 210 via a coupling. Two second guide rods 207 are mounted parallel to each other on the bottom surface of the second bearing plate 206 via smooth rod support seats, and are symmetrical to the second lead screw 210. The second lead screw 210... The left section of the second lead screw 207 is fitted with a left-hand nut (omitted in the figure), and the right section of the second lead screw 210 is fitted with a right-hand nut (omitted in the figure). The left and right T-shaped positioning plates 208 are respectively mounted on the left and right sections of the second guide rod 207 via linear bearings, and are respectively fixedly connected to the left-hand nut fitted on the left section of the second lead screw 210 and the right-hand nut fitted on the right section of the second lead screw 210. The L-shaped positioning plate 211 is fixedly installed on one side of the bottom surface of the second bearing plate 206, and its direction is perpendicular to the T-shaped positioning plate 208.

[0060] The working process of blank positioning component 2 is as follows:

[0061] 1) The piston rod of the second double-rod cylinder 205 extends, causing the second bearing plate 206 to move downward;

[0062] 2) The blank supply component 1 pushes the blank 5 to the electromagnetic chuck 405 directly below the blank positioning component 2, and the L-shaped positioning plate 211 realizes the positioning of the blank 5 in one direction.

[0063] 3) The second motor 209 starts, driving the two T-shaped positioning plates 208 on the left and right to close together, realizing the positioning of the blank 5 in another direction;

[0064] 4) The electromagnetic chuck 405 is energized, fixing the positioned blank 5;

[0065] 5) Motor 209 rotates in the opposite direction, causing the two T-shaped positioning plates 208 on the left and right to open;

[0066] 6) The piston rod of the second double-rod cylinder 205 retracts, causing the second bearing plate 206 to move upward and return to the initial position.

[0067] like Figure 11 and 12 As shown, the peripheral milling component 3 includes a third support leg 301, a third top plate 302, a third milling head 303, a third longitudinal motor 304, a third longitudinal lead screw 305, a third longitudinal guide rail 306, a third transverse guide rail 307, a third transverse lead screw 308, a third longitudinal slider 309, a third transverse slider 310, a third longitudinal drive plate 311, a third transverse drive plate 312, and a third transverse motor 313. Figure 11As shown, several No. 3 support legs 301 are installed on the bottom surface of the No. 3 top plate 302, forming the overall support frame of the peripheral milling component 3. Figure 12 As shown, the No. 3 longitudinal lead screw 305 is mounted in the middle of the bottom surface of the No. 3 top plate 302 via a bearing seat. The No. 3 longitudinal motor 304 is mounted at one end of the bottom surface of the No. 3 top plate 302 via a motor mounting bracket. The output shaft of the No. 3 longitudinal motor 304 is connected to the No. 3 longitudinal lead screw 305 via a coupling. Two No. 3 longitudinal guide rails 306 are mounted parallel to each other on the bottom surface of the No. 3 top plate 302 and are symmetrical to the No. 3 longitudinal lead screw 305. A No. 3 longitudinal slider 309 is mounted on the two No. 3 longitudinal guide rails 306. The No. 3 longitudinal drive plate 311 is mounted on the two No. 3 longitudinal guide rails 306 via the No. 3 longitudinal slider 309 and is fixedly connected to the nut mounted on the No. 3 longitudinal lead screw 305. When the output shaft of the No. 3 longitudinal motor 304 rotates, the No. 3 longitudinal drive plate 311 is driven to move along the No. 3 longitudinal guide rails 306 via the lead screw and nut mechanism, which constitutes the longitudinal feed motion of the peripheral milling component 3. The third transverse lead screw 308 is mounted in the middle of the bottom surface of the third longitudinal drive plate 311 via a bearing seat. The third transverse motor 313 is mounted at one end of the bottom surface of the third longitudinal drive plate 311 via a motor mounting bracket. The output shaft of the third transverse motor 313 is connected to the third transverse lead screw 308 via a coupling. Two third transverse guide rails 307 are mounted parallel to each other on the bottom surface of the third longitudinal drive plate 311 and symmetrical to the third transverse lead screw 308. A third transverse slider 310 is mounted on the two third transverse guide rails 307. The third transverse drive plate 312 is mounted on the two third transverse guide rails 307 via the third transverse slider 310 and is fixedly connected to the nut mounted on the third transverse lead screw 308. When the output shaft of the third transverse motor 313 rotates, it drives the third transverse drive plate 312 to move along the third transverse guide rails 307 through the lead screw and nut mechanism, thus constituting the transverse feed motion of the peripheral milling component 3. Milling head 303 is mounted on transverse drive plate 312.

[0068] like Figure 13As shown, the conveying component 4 includes a fourth support leg 401, a U-shaped support plate 402, a fourth motor 403, a fourth drive plate 404, an electromagnetic chuck 405, a fourth lead screw 406, a fourth bearing with a seat 407, a fourth slider 408, and a fourth guide rail 409. Several fourth support legs 401 are mounted on the bottom surface of the U-shaped support plate 402, forming the overall support frame of the conveying component 4. The fourth lead screw 406 is mounted in the middle of the top surface of the U-shaped support plate 402 via the fourth bearing 407. The fourth motor 403 is mounted at one end of the top surface of the U-shaped support plate 402 via a motor mounting bracket. The output shaft of the fourth motor 403 is connected to the fourth lead screw 406 via a coupling. Two fourth guide rails 409 are mounted parallel to each other on the top surface of the U-shaped support plate 402 and symmetrical to the fourth lead screw 406. A fourth slider 408 is mounted on the two fourth guide rails 409. The fourth drive plate 404 is mounted on the two fourth guide rails 409 via the fourth slider 408 and is fixedly connected to the nut mounted on the fourth lead screw 406. An electromagnetic chuck 405 is mounted on the fourth drive plate 404. When the output shaft of the fourth motor 403 rotates, it drives the fourth drive plate 404 and the electromagnetic chuck 405 mounted on it to move along the fourth guide rails 409 through the lead screw and nut mechanism.

When the output shaft of the No. 3 longitudinal motor rotates, it drives the No. 3 longitudinal drive plate to move along the No. 3 longitudinal guide rail, forming the longitudinal feed motion of the peripheral milling component. The No. 3 milling head mills the blank around its perimeter through interpolation, processing it into a semi-finished product. The output shaft of motor No. 4 rotates, driving the No. 4 drive plate, the electromagnetic chuck mounted on it, and the semi-finished product adsorbed on the electromagnetic chuck to move along the No. 4 guide rail until they are at the right end of the conveying component, completing the processing.
