Description

Technical Field

[0001] The invention relates to the technical field of workpiece milling equipment, and in particular to equipment for milling the end face of a casting, which can perform double-sided milling on a workpiece with a positioning hole and a workpiece without a positioning hole. Background Art

[0002] Some castings need to be milled after processing. For example, the corner pieces in logistics container castings need to be cut and separated by corresponding cutting equipment after casting and then milled by corresponding milling equipment.

[0003] At present, the end face milling processing equipment used for container corner castings mainly adopts a double-sided milling machine, which fixes the container corner castings to the corresponding fixtures through the corresponding manipulators, and then transfers the fixtures with the workpieces installed through the main spindle heads of the double-sided milling machine through the mobile workbench to complete the milling processing of the two end faces of the workpiece at one time. The fixtures used in the existing end face milling processing equipment for container corner castings generally include a fixture base for fixing the workpiece, and a downward pressure cylinder arranged on the top of the fixture base. The downward pressure block arranged at the piston rod end of the downward pressure cylinder cooperates with the fixture base to form an upper and lower clamping of the workpiece. Since the container corner castings are generally hollow, and corresponding positioning holes are arranged on the three end faces thereof, and in order to ensure the stability of the clamping, the clamping preload force is relatively high, therefore, the container corner castings are prone to deformation during the clamping process, resulting in the machining accuracy failing to meet the design requirements.

[0004] Therefore, the purpose of the present invention is to design a device that can simultaneously form longitudinal and transverse clamping pre-tightening forces on the workpiece, thereby enhancing the clamping stability of the container corner casting and reducing the longitudinal clamping pre-tightening force of the container corner casting. Furthermore, while ensuring the clamping stability of the workpiece, it is effectively prevented that the machining accuracy does not meet the design requirements due to excessive longitudinal clamping pre-tightening force. This is the research purpose of the present invention. Summary of the invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a device for milling the end face of a casting, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is:

[0007] A casting end face milling device, comprising:

[0008] A double-sided milling machine, wherein a corresponding movable workbench is movably arranged in the middle of the double-sided milling machine, and a corresponding tool fixing seat is fixedly connected to the movable workbench;

[0009] The cam is fixedly mounted on the workbench, and the cam is secured to the upper and lower surfaces of the workbench and is used for mounting the cams on the workbench. The cams are secured to the upper and lower surfaces of the workbench and are used for mounting the cams on the workbench.

[0010] The top end of the limit rod is provided with a limit sleeve, and the top end face of the limit rod is provided with a limit sleeve that is flush with the top end face of the support plate. When the limit rod is fixed to the plug hole by a threaded connection, the top end face of the limit rod is fixedly sleeved with a limit sleeve whose top end face is flush with the top end face of the support plate. When the bottom end of the limit rod is located at the lower side of the plug hole, the upper part of the limit rod can be movably inserted into the plug hole, and when the limit rod is pressed down to be flush with the upper end face of the tooling base, the buffer spring is compressed.

[0011] The loading mechanism is used to transport the workpiece to the position of the support plate of the horizontal clamping mechanism. The loading mechanism includes a loading robot and a workpiece fixing mechanism arranged on the loading robot. The workpiece fixing mechanism includes a fixing plate fixed to the loading robot, one side of the fixing plate is fixed downwardly with an L-shaped clamping plate, and the lower part of the other side of the fixing plate is fixed with a pushing cylinder for pushing the workpiece onto the L-shaped clamping plate.

[0012] The top of the L-shaped clamping plate is tilted downward and fixedly connected with a corresponding connecting plate, and corresponding abutment balls are respectively installed in a rolling manner on both sides of the connecting plate, and an electromagnet is fixedly connected between the abutment balls, and its bottom surface is located on the upper side of the bottom end of the abutment ball; the electromagnet is energized to adsorb and lift the side of the workpiece close to the L-shaped clamping plate, and the side of the workpiece close to the L-shaped clamping plate rises and abuts against the bottom end of the abutment ball, and after the piston rod of the pushing cylinder is extended to push the workpiece to move toward one side of the L-shaped clamping plate, the electromagnet is de-energized, and the side of the workpiece close to the L-shaped clamping plate is fixedly clamped on the L-shaped clamping plate.

[0013] A number of corresponding tightening bolts are evenly fixed on the L-shaped clamping plate on the lower side of the connecting plate. After the electromagnet is powered off, the piston rod of the pushing cylinder continues to extend to fix the workpiece between the pushing cylinder, the tightening bolts, and the L-shaped clamping plate.

[0014] The loading robot adopts a three-axis truss robot, which includes a group of X-axes supported and installed by corresponding columns, a group of X-axes with corresponding Y-axes installed longitudinally and movably, the Y-axes with corresponding Z-axis mounting seats installed transversely and movably, the Z-axis mounting seats with corresponding Z-axes installed movably and liftably, and the fixed plate is horizontally fixed to the Z-axis.

[0015] The Y-axis, Z-axis mounting seat, and Z-axis are driven by corresponding gear rack driving mechanisms respectively.

[0016] The two sides of the tightening block are respectively fixedly connected with corresponding abutment pieces by means of bolt locking, and the abutment pieces are made of engineering plastics.

[0017] The tooling fixing seat is upwardly fixed with at least two corresponding vertical arms, the tops of the vertical arms are laterally extended outward and fixed with corresponding guide rails, corresponding fixed beams are movably mounted on the guide rails, and the downward pressure cylinder is fixed to the fixed beams.

[0018] A corresponding beam driving cylinder is fixedly connected to the fixed beam, and a piston rod end of the beam driving cylinder is connected to the corresponding vertical arm.

[0019] A corresponding crimping piece is fixedly connected downwardly to the piston rod end of the pressing oil cylinder, and the piston rod of the pressing oil cylinder extends out to drive the crimping piece to be fixedly crimped on the upper end surface of the workpiece.

[0020] The bottom side of the crimping piece is fixedly connected downwardly with a corresponding abutment plate through a corresponding vibration-damping gasket, and a plurality of corresponding vibration-damping micropores are evenly distributed on the vibration-damping gasket; a plurality of corresponding guide holes are evenly distributed on the crimping piece, and the vibration-damping gasket is respectively provided with corresponding vibration-damping sleeves at positions corresponding to the guide holes, the vibration-damping sleeves extend through and extend to the outside of the corresponding guide holes, and are fixedly filled with a plurality of corresponding vibration-damping damping particles, and a gap is provided between the outer wall of the vibration-damping sleeve and the guide hole.

[0021] Advantages of the present invention:

[0022] 1) When fixing the container corner casting, the present invention firstly drives the push member to move upward by the oil cylinder to drive the push member to move synchronously inward, thereby facilitating the fixed installation of the container corner casting. When the container corner casting is fixed to the transverse clamping mechanism, the positioning hole provided on the container corner casting is sleeved on the periphery of the U-shaped clamping block; after the workpiece is installed in place, the downward pressure oil cylinder moves downward to form a downward pressure clamping on the workpiece until the limit rod is pressed down to be flush with the upper end surface of the tooling base. At this time, the buffer spring is compressed to provide a positioning hole for the workpiece that is not provided with a positioning hole. The position is pushed upward, thereby forming a uniform and reasonable longitudinal clamping pre-tightening force on the workpiece; finally, the push member drives the oil cylinder to drive the push member downward, so as to drive the tightening block to move outward synchronously, thereby tightening it to the positioning hole of the container corner casting, so as to simultaneously form longitudinal and transverse clamping pre-tightening force on the workpiece, so as to strengthen the clamping stability of the container corner casting and reduce the longitudinal clamping pre-tightening force of the container corner, thereby effectively preventing the problem of machining accuracy not meeting the design requirements due to excessive longitudinal clamping pre-tightening force while ensuring the clamping stability of the workpiece.

[0023] Synchronously form longitudinal and transverse clamping pre-tightening force on the workpiece, which can also ensure the verticality of the workpiece clamping to ensure that the milled workpiece will not have an inclined surface and cause failure.

[0024] 2) The bottom side of the limiting rod of the longitudinal clamping mechanism of the present invention is provided with an external thread, and the upper part of the plug hole is provided with an internal thread that matches the external thread of the limiting rod. When the limiting rod is fixedly installed to the plug hole by threaded connection, the top end of the limiting rod is fixedly sleeved with a limiting sleeve whose top end surface is flush with the top end surface of the support plate. Thus, the use condition of the longitudinal clamping mechanism is switched, so that the support plate and the limiting sleeve together form a sufficient installation plane, so as to cooperate with the downward pressure cylinder to fix and install other castings without positioning holes, so that castings other than container corner parts can also be firmly clamped for end face milling, so as to greatly improve the adaptability of the equipment, that is, greatly improve the utilization rate of the equipment.

[0025] 3) In addition to the L-shaped clamping plate and the pushing cylinder that pushes the workpiece onto the L-shaped clamping plate, the feeding mechanism of the present invention further has a connecting plate fixedly connected to the top of the L-shaped clamping plate in a downward tilt, and two rows of abutment balls are respectively installed on both sides of the connecting plate in a rolling manner, and an electromagnet with a bottom surface located on the upper side of the bottom end of the abutment balls is fixedly connected between the abutment balls. This is because: when the workpiece is directly pushed to the upper side of the bottom of the L-shaped clamping plate by the pushing cylinder, the side of the workpiece close to the L-shaped clamping plate will inevitably be greatly scratched by the bottom of the L-shaped clamping plate, thereby causing irreversible surface mechanical damage to the workpiece. Through the arrangement of the connecting plate, the abutting ball, and the electromagnet of the present invention, the electromagnet can be energized in advance to effectively adsorb and lift the side of the workpiece close to the L-shaped clamping plate before the workpiece is loaded and fixed. The side of the workpiece close to the L-shaped clamping plate rises and abuts against the bottom end of the abutting ball. At this time, the piston rod of the push cylinder is extended to push the workpiece to move smoothly to one side of the L-shaped clamping plate. The subsequent electromagnet is powered off to fix the side of the workpiece close to the L-shaped clamping plate on the L-shaped clamping plate. Therefore, the transportation stability of the workpiece during the loading process is ensured on the premise of solving the problem of mechanical damage to the workpiece surface existing in the use of the L-shaped clamping plate.

[0026] 4) A number of corresponding tightening bolts are evenly fixed on the L-shaped clamping plate on the lower side of the connecting plate of the present invention. After the electromagnet is powered off, the piston rod of the pushing cylinder continues to extend to fix the workpiece between the pushing cylinder, the tightening bolts, and the L-shaped clamping plate, thereby forming a stable limit for the workpiece with clamping on both sides and single-sided support on the bottom, so as to further ensure the transportation stability of the workpiece during the loading process.

[0027] 5) Since the processing surface of double-sided milling is relatively large, the vibration generated by the processing is more obvious. For this reason, the bottom side of the crimping part of the present invention is fixed downward with an abutment plate through a corresponding vibration-damping gasket. During the clamping process, the abutment plate directly presses the top surface of the workpiece. When the vibration generated by the processing is transmitted through the vibration-damping gasket, resonance is formed in the vibration-damping microholes, thereby forming preliminary vibration reduction; the vibration can also be partially transmitted to the vibration-damping sleeve, thereby effectively further forming vibration reduction without affecting the normal operation of the downward pressure cylinder, so as to significantly improve the milling accuracy of the product through vibration reduction.

DETAILED DESCRIPTION

[0037] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0038] refer to Figure 1-8 , a casting end face milling processing equipment, comprising

[0039] A double-sided milling machine 1, wherein a corresponding movable workbench 2 is movably provided in the middle of the double-sided milling machine 1, and a corresponding tool fixing seat 3 is fixedly connected to the movable workbench 2;

[0040] The horizontal clamping mechanism 4 comprises a plurality of tooling bases 401 fixedly connected to the tooling fixing seat 3 in parallel, wherein a U-shaped clamping block 402 with an opening facing upward is fixedly installed in the middle of each tooling base 401, a corresponding support plate 403 is fixedly installed on the top of each U-shaped clamping block 402, and corresponding blocking members 404 are movably installed up and down between the two ends of each U-shaped clamping block 402, and the two sides of each blocking member 404 are respectively arranged in an inclined shape and convexly provided with corresponding clamping portions 4041, and the blocking member 404 is installed on the tooling fixing seat 3. The push-block driving cylinder 405 in the fixed seat 3 is driven; corresponding tightening blocks 406 are respectively installed on both sides of the push-block 404, and the inner side of the tightening block 406 is set to be an inclined surface adapted to the push-block 404, and is provided with a limiting slide groove 4061 clamped to the clamping portion 4041, and the push-block driving cylinder 405 drives the push-block 404 upward, driving the tightening block 406 to move inward, and the push-block driving cylinder 405 drives the push-block 404 downward, driving the tightening block 406 to move outward;

[0041] The longitudinal clamping mechanism 5 has a group of corresponding plug-in holes 6 on both sides of the tooling base 401, and the longitudinal clamping mechanism 5 includes a limit rod 501 plugged into the plug-in hole 6, and a downward pressure cylinder 502 arranged on the upper side of the tooling base 401, and corresponding buffer springs 503 are fixedly installed in the plug-in hole 6 at the bottom of the limit rod 501; the bottom side of the limit rod 501 is provided with a corresponding external thread, and the upper part of the plug-in hole 6 is provided with a thread corresponding to the external thread of the limit rod 501. The limiting rod 501 is fixedly mounted to the plug hole 6 by threaded connection, and the top end of the limiting rod 501 is fixedly sleeved with a limiting sleeve 504 whose top end surface is flush with the top end surface of the support plate 403; when the bottom of the limiting rod 501 is located at the lower side of the plug hole 6, the upper part of the limiting rod 501 can be movably inserted into the plug hole 6, and when the limiting rod 501 is pressed down to be flush with the upper end surface of the tooling base 401, the buffer spring 503 is compressed;

[0042] The loading mechanism 7 is used to transport the workpiece 8 to the position of the support plate 403 of the horizontal clamping mechanism 4. The loading mechanism 7 includes a loading robot 701 and a workpiece fixing mechanism 702 arranged on the loading robot 701. The workpiece fixing mechanism 702 includes a fixing plate 7021 fixedly connected to the loading robot 701, and an L-shaped clamping plate 7022 is fixedly connected downwardly to one side of the fixing plate 7021, and a pushing cylinder 7023 for pushing the workpiece 8 onto the L-shaped clamping plate 7022 is fixedly connected to the lower part of the other side of the fixing plate 7021.

[0043] When the workpiece 8 is fixed, the push member driving cylinder 405 first drives the push member 404 upward to drive the clamping block 406 to move inward synchronously, thereby facilitating the fixed installation of the workpiece 8. When the workpiece 8 is fixed to the horizontal clamping mechanism 4, the positioning hole set on the workpiece 8 is sleeved on the periphery of the U-shaped clamping block 402; after the workpiece 8 is installed in place, the downward pressure cylinder 502 moves downward to form a downward pressure clamping on the workpiece 8 until the limiting rod 501 is pressed down to be flush with the upper end surface of the tooling base 401. At this time, the buffer spring 503 is compressed to clamp the workpiece 8 that is not set The position where the positioning hole is arranged forms an upward push, thereby forming a uniform and reasonable longitudinal clamping pre-tightening force on the workpiece 8; finally, the push member drives the oil cylinder 405 to drive the push member downward to drive the clamping block 406 to move outward synchronously, thereby pressing against the positioning hole of the workpiece 8, thereby being able to simultaneously form longitudinal and transverse clamping pre-tightening forces on the workpiece 8, so as to strengthen the clamping stability of the workpiece 8 and reduce the longitudinal clamping pre-tightening force of the workpiece 8, thereby ensuring the clamping stability of the workpiece 8 while effectively preventing the problem of machining accuracy not meeting the design requirements due to excessive longitudinal clamping pre-tightening force.

[0044] The bottom side of the limiting rod 501 of the longitudinal clamping mechanism 5 of the present invention is provided with an external thread, and the upper part of the plug hole 6 is provided with an internal thread matched with the external thread of the limiting rod 501. When the limiting rod 501 is fixedly installed to the plug hole 6 by threaded connection, the top end of the limiting rod 501 is fixedly sleeved with a limiting sleeve 504 whose top end surface is flush with the top end surface of the support plate 403. Thus, the use condition of the longitudinal clamping mechanism 5 is switched, so that the support plate 403 and the limiting sleeve 504 form a sufficient installation plane together, so as to cooperate with the downward pressure cylinder 502 to fix and install other castings without positioning holes, so that castings other than the container corner parts can also be firmly clamped and processed by end face milling, so as to greatly improve the use adaptability of the equipment, that is, greatly improve the utilization rate of the equipment. When the container corner piece needs to be milled again, the limiting sleeve 504 is removed, and the limiting rod 501 is screwed down until the portion of the limiting rod 501 provided with the external thread falls into the insertion hole 6.

[0045] The top of the L-shaped clamping plate 7022 is tilted downward and fixedly connected with a corresponding connecting plate 9, and corresponding abutment balls 10 are respectively rollingly installed on both sides of the connecting plate 9, and an electromagnet 11 is fixedly connected between the abutment balls 10, and the bottom surface of the electromagnet is located on the upper side of the bottom end of the abutment ball 10; the electromagnet 11 is energized to adsorb and lift the side of the workpiece 8 close to the L-shaped clamping plate 7022, and the side of the workpiece 8 close to the L-shaped clamping plate 7022 rises and abuts against the bottom end of the abutment ball 10, and after the piston rod of the pushing cylinder 7023 is extended to push the workpiece 8 to move toward one side of the L-shaped clamping plate 7022, the electromagnet 11 is de-energized, and the side of the workpiece 8 close to the L-shaped clamping plate 7022 is fixedly clamped on the L-shaped clamping plate 7022.

[0046] When the workpiece 8 is directly pushed to the upper side of the bottom of the L-shaped clamping plate 7022 by the push cylinder 7023, the side of the workpiece 8 close to the L-shaped clamping plate 7022 will inevitably be greatly scratched by the bottom of the L-shaped clamping plate 7022, thereby causing irreversible surface mechanical damage to the workpiece 8. Through the arrangement of the connecting plate 9, the abutting ball 10, and the electromagnet 11 of the present invention, the electromagnet 11 can be effectively energized in advance before the workpiece 8 is loaded and fixed to adsorb and lift the side of the workpiece 8 close to the L-shaped clamping plate 7022. The side of the workpiece 8 close to the L-shaped clamping plate 7022 rises and abuts against the bottom end of the abutting ball 10. At this time, the piston rod of the push cylinder 7023 is extended to push the workpiece 8 to move smoothly to the side of the L-shaped clamping plate 7022. The subsequent electromagnet 11 is powered off, so that the side of the workpiece 8 close to the L-shaped clamping plate 7022 can be fixedly clamped on the L-shaped clamping plate 7022. Therefore, the transportation stability of the workpiece 8 during the loading process is ensured while solving the problem of mechanical damage to the surface of the workpiece 8 when using the L-shaped pallet 7022.

[0047] A plurality of corresponding jacking bolts 12 are evenly fixed on the L-shaped clamping plate 7022 at the lower side of the connecting plate 9. After the electromagnet 11 is powered off, the piston rod of the push cylinder 7023 continues to extend to fix the workpiece 8 between the push cylinder 7023, the jacking bolts 12, and the L-shaped clamping plate 7022. Thus, the workpiece 8 can be clamped on both sides and supported on one side at the bottom to further ensure the transportation stability of the workpiece 8 during the loading process.

[0048] The loading robot 701 adopts a three-axis truss robot, which includes a group of X-axes 7012 supported and installed by corresponding columns 7011, a group of X-axes 7012 are longitudinally movably installed with corresponding Y-axes 7013, the Y-axes 7013 are laterally movably installed with corresponding Z-axis mounting seats 7014, the Z-axis mounting seats 7014 are liftably installed with corresponding Z-axes 7015, and the fixed plate 7021 is horizontally fixed to the Z-axes 7015.

[0049] The Y-axis 7013 , the Z-axis mounting seat 7014 , and the Z-axis 7015 are driven by corresponding gear rack driving mechanisms 13 , respectively.

[0050] The two sides of the tightening block 406 are respectively fixed with corresponding abutment members 14 by bolt locking, and the abutment members 14 are made of engineering plastics.

[0051] The tooling fixing seat 3 is fixedly connected upward with at least two corresponding vertical arms 15, the top of the vertical arms 15 is extended outward laterally and fixedly connected with corresponding guide rails 16, and a corresponding fixed crossbeam 17 is movably mounted on the guide rail 16, and the downward pressure cylinder 502 is fixedly connected to the fixed crossbeam 17.

[0052] A corresponding beam driving cylinder 18 is fixedly connected to the fixed beam 17 , and a piston rod end of the beam driving cylinder 18 is connected to the corresponding vertical arm 15 .

[0053] The piston rod end of the pressing cylinder 502 is fixedly connected downward with a corresponding crimping piece 19 , and the piston rod of the pressing cylinder 502 extends to drive the crimping piece 19 to be fixedly crimped onto the upper end surface of the workpiece 8 .

[0054] The bottom side of the crimping piece 19 is fixed downwardly with a corresponding abutment plate 21 through a corresponding vibration-damping gasket 20, and a plurality of corresponding vibration-damping micropores are evenly distributed on the vibration-damping gasket 20; a plurality of corresponding guide holes are evenly distributed on the crimping piece 19, and the vibration-damping gasket 20 is respectively provided with corresponding vibration-damping sleeves 22 at positions corresponding to the guide holes, and the vibration-damping sleeves 22 extend through and extend to the outside of the corresponding guide holes and are fixedly filled with a plurality of corresponding vibration-damping damping particles, and a gap is provided between the outer wall of the vibration-damping sleeve 22 and the guide hole.

[0055] During the clamping process, the abutment plate 21 directly presses the top surface of the workpiece 8. When the vibration generated by the processing is transmitted through the vibration-damping gasket 20, resonance is formed in the vibration-damping microholes, thereby forming preliminary vibration reduction. The vibration can also be partially transmitted to the vibration-damping sleeve 22, thereby effectively further forming vibration reduction without affecting the normal operation of the downward pressure cylinder 502, so as to significantly improve the milling accuracy of the product through vibration reduction.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
