Abstract

This invention relates to the field of parts processing technology, and in particular to a turning device and its control method for machining machine tool crossbeams. The invention includes a base frame, with a support mechanism, a drive mechanism, and a reciprocating seat mounted on the top of the base frame. The support mechanism supports the crossbeam, and the drive mechanism drives the reciprocating seat to move. A turning mechanism is installed inside the reciprocating seat to mill the crossbeam. A negative pressure space is first formed by a coiling and collecting component, which facilitates the adsorption of long debris using suction, allowing the long debris to enter the coiling and collecting component. If the long debris adheres to the workpiece and does not detach, suction is used to guide the weakly adhering debris away from the workpiece surface, thus reducing the likelihood of long debris adhering to the workpiece and adversely affecting its final shape.

Description

Technical Field

[0001] This invention relates to the field of parts processing, and in particular to a turning device and its control method for machining machine tool beams. Background Technology

[0002] The machine tool crossbeam is an indispensable part of the machine tool structure. It usually refers to a large horizontal beam-shaped component that connects the two ends of the machine tool bed and spans the entire working area.

[0003] In the prior art, when a beam is cut using a turning machine, the resulting chips exhibit significant plastic bending characteristics, with particularly sharp edges. Especially when high-speed cutting steel workpieces is performed, these chips rapidly heat up to a red-hot state and are quite long. Such chips not only pose a significant personal safety hazard to operators and are prone to causing scratches, but they also often become entangled in the workpiece and the turned parts, thus adversely affecting the final shape of the workpiece. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a turning device and its control method for machining machine tool beams.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a turning device for machining a machine tool crossbeam, comprising a base frame, a support mechanism, a drive mechanism, and a reciprocating seat disposed on the top of the base frame, the support mechanism being used to support the crossbeam, the drive mechanism being used to drive the reciprocating seat to move, and a turning mechanism disposed inside the reciprocating seat, the turning mechanism being used to mill the crossbeam, and further comprising:

[0006] A monitoring unit, located inside the reciprocating seat, is used to monitor whether the milled chips are too long.

[0007] Two sets of coiling and pressing assemblies are symmetrically arranged on both sides of the turning mechanism;

[0008] The control unit is fixedly installed on the side wall of the reciprocating seat. When the monitoring unit detects that the chip is too long, it controls the winding and gathering assembly to start working, so as to cause the weakly attached chips to separate from the workpiece surface under the action of suction, and effectively wind and organize the remaining chips.

[0009] The coiling and gathering assembly first fixes the end of the long debris and then rotates to coil it up. This coiling helps prevent the debris from returning to the workpiece and affecting the processing, and also helps prevent the debris residue from scratching the operator. Furthermore, the pulling force generated during the coiling process applies force to the closely adhered long debris, which helps to quickly separate the long debris from the workpiece and effectively avoids the problem of debris adhering to the workpiece and being difficult to remove.

[0057] The controller sends third control information to the actuator to control the actuator to initiate contraction;

[0058] The controller sends the fourth control information to the motor to control the motor to start working and drive the rotating column to rotate.

[0059] Compared with the prior art, the present invention has the following beneficial effects:

[0060] 1. This invention, through the configuration of a coiling and gathering component, first creates a negative pressure space, which facilitates the adsorption of long debris using suction. This allows the long debris to enter the interior of the coiling and gathering component. If the long debris adheres to the workpiece and remains attached, the suction force guides the weakly adhered debris to detach from the workpiece surface. This reduces the likelihood of long debris adhering to the workpiece and negatively impacting its final shape. If the long debris adheres tightly to the workpiece, the suction force... When it is difficult to separate the debris from the workpiece, the coiling and gathering assembly first fixes the end of the long debris and then rotates to coil it up. On the one hand, coiling up the long debris helps to prevent it from returning to the workpiece and affecting the processing, and also helps to prevent the long debris residue from scratching the operator. On the other hand, the pulling force generated during the coiling process applies force to the long debris that is closely adhered, which helps to quickly separate the long debris from the workpiece, effectively avoiding the problem of debris adhering to the workpiece and being difficult to remove.

[0061] 2. The present invention, through the setting of the slitting blade, moves the blade position of the slitting blade down to the first extrusion block and the second extrusion block. After the slitting blade slides out from the inside of the sliding groove, the elastic element releases elastic force to push the slitting blade out from the inside of the groove. At the same time, the blade can cut the long debris that has been wrapped between the first and second extrusion blocks. The additional force provided by the elastic element helps the slitting blade to cut the debris more effectively, thereby promoting the efficient handling of debris and facilitating the rapid division of debris into small segments.

[0062] 3. By setting up the roller, when the first extrusion block and the second extrusion block are performing the winding operation on long debris, the long debris will come into contact with the stationary outer wall of the roller. Because the roller has the ability to rotate on its own, this will help reduce the frictional resistance generated between the long debris and the roller. Furthermore, thanks to this physical constraint of the roller, the long debris cannot deflect outwards, and the long debris can be more smoothly rolled up and collected by the first extrusion block and the second extrusion block.

[0077] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0078] Application scenario: In the existing technology, when using turning equipment to cut crossbeams, the resulting chips exhibit significant plastic bending characteristics, with particularly sharp edges. Especially when high-speed cutting steel workpieces, these chips rapidly heat up to a red-hot state and are quite long. Such chips not only pose a great personal safety hazard to operators and are prone to causing scratches, but they also often become entangled in the workpiece and the turned parts, thus adversely affecting the final shape of the workpiece.

[0079] like Figures 2 to 13 A turning device for machining a machine tool crossbeam is shown, comprising a base frame (1), a support mechanism, a drive mechanism, and a reciprocating seat (2) on the top of the base frame (1). The support mechanism is used to support the crossbeam, the drive mechanism is used to drive the reciprocating seat (2) to move, and a turning mechanism is provided inside the reciprocating seat (2) for milling the crossbeam. The device also includes:

[0080] The monitoring unit is located inside the reciprocating seat (2) and is used to monitor whether the milled chips are too long.

[0081] Two sets of coiling and pressing assemblies are symmetrically arranged on both sides of the turning mechanism;

[0082] The control unit is fixedly installed on the side wall of the reciprocating seat (2). When the monitoring unit detects that the chip is too long, it controls the winding and gathering assembly to start working so that the chip with weak adhesion is separated from the workpiece surface under the suction force, and the remaining chip is effectively rolled and organized.

[0083] In specific implementation, the machine tool beam to be processed is placed on the support mechanism for limit fixation, and then the turning mechanism is adjusted to a suitable height. The drive mechanism is started, and the reciprocating seat (2) is moved by the drive mechanism. The reciprocating seat (2) drives the turning mechanism to start, so that the turning mechanism can mill the target workpiece during the movement to achieve the expected processing shape.

[0084] During this process, the monitoring unit monitors the chips generated during turning in real time. When the monitoring unit detects that the chips generated during milling exceed the predetermined length, it controls the coiling and gathering component to start working. The coiling and gathering component first forms a negative pressure space, which facilitates the adsorption of long chips using suction. This allows the long chips to enter the interior of the coiling and gathering component. If the long chips are still adhered to the workpiece, the suction force guides the chips with weaker adhesion to detach from the workpiece surface. This helps reduce the occurrence of long chips adhering to the workpiece and adversely affecting the final shape shaping of the workpiece. If long chips adhere tightly to the workpiece, it is difficult to detach them using adsorption. In this case, the coiling and gathering assembly first fixes the end of the long chip and then rotates to coil it up. This coiling helps prevent the chips from returning to the workpiece and affecting the processing, and also helps prevent the chips from causing scratches to the operator. Furthermore, the pulling force generated during the coiling process applies force to the closely adhered long chips, which helps to quickly separate them from the workpiece and effectively avoids the problem of chips adhering to the workpiece and being difficult to remove.

[0085] It should be further explained that the monitoring unit is specifically a camera (3), which is fixedly installed inside the reciprocating seat (2) and is used to take pictures and identify the chips generated during the turning process in order to determine whether the chip length exceeds the predetermined value.

[0086] Among them, the camera (3) can take pictures and recognize objects in 360 degrees. The camera 3 is used as a tool to obtain image information. Combined with specific software algorithms or applications, it can take pictures and recognize the length of objects. This is an existing mature technology and will not be disclosed in detail here.

[0087] It should be noted that the supporting mechanism is a conventional technology and will not be disclosed in detail here.

[0088] It should be noted again that the control unit is specifically a controller, which is fixedly installed on the side wall of the reciprocating seat 2.

[0089] As a technical optimization of the present invention: the turning mechanism includes:

[0090] The first motor (4) is fixedly installed on the top of the reciprocating seat (2);

[0091] The first threaded rod (5) is fixedly installed on the output shaft end of the first motor (4). The end of the first threaded rod (5) away from the first motor (4) is rotatably connected to a fixing plate (6). The bottom of the fixing plate (6) is fixedly installed on the top of the reciprocating seat (2).

[0092] A through groove (7) is formed on the reciprocating seat (2);

[0093] A threaded seat (8) is threadedly connected to the outer wall of the first threaded rod (5), and the bottom of the threaded seat (8) passes through the through groove (7) and is fixedly connected to a power box (9);

[0094] A cutting tool (10) is fixedly installed inside the power box (9) via a power assembly;

[0095] In specific implementation, the first motor (4) is started, and the first threaded rod (5) is rotated by the first motor (4). The rotation of the first threaded rod (5) drives the threaded seat (8) to move along a predetermined trajectory. The threaded seat (8) drives the power box (9) to move. The power box (9) drives the cutting tool (10) to move through the power assembly. The power assembly provides a power source for the cutting tool (10) so that the height of the cutting tool (10) relative to the target workpiece can be adjusted, and corresponding power is provided for the rotation of the cutting tool (10), which is beneficial for milling the target workpiece during the movement of the cutting tool (10).

[0096] It should be noted that the power assembly includes existing components such as a third motor (34) and an electric actuator to complete the rotation and height adjustment of the cutting tool (10), which is a conventional technology and will not be disclosed in detail here.

[0097] As a technical optimization of the present invention: the coiling and pressing assembly includes:

[0098] Ventilation box (11), the ventilation box (11) is fixedly connected to the side wall of the power box (9) by a mounting base;

[0099] Ventilation duct (12) is fixedly installed inside the ventilation box (11);

[0100] An exhaust component (13) is fixedly installed on the side wall of the ventilation box (11), and the air inlet of the exhaust component (13) is fixedly connected to the ventilation duct (12) through an exhaust pipe;

[0101] The second motor (14) is fixedly installed on the top of the ventilation box (11);

[0102] A rotating column (15) is fixedly installed at the output shaft end of the second motor (14), and the rotating column (15) is located inside the ventilation cylinder (12);

[0103] A circular ring (16) is fixedly installed on the outer wall of the rotating column (15);

[0104] Two pushers (17) are symmetrically fixedly installed at the bottom of the ring (16);

[0105] The disc (18) is fixedly installed at the telescopic ends of the two pushers (17);

[0106] Multiple ventilation slots (19) are arranged in a circular array on the disk (18);

[0107] The first extrusion block (20) is fixedly installed at the bottom center of the disk (18);

[0108] An electromagnet (21) is fixedly embedded in the bottom of the first extrusion block (20);

[0109] The second extrusion block (22) is vertically slidably sleeved on the outer wall of the rotating column (15);

[0110] The first extrusion block (20), the second extrusion block (22), and the electromagnet (21) are all sleeved on the outer wall of the rotating column (15);

[0111] In specific implementation, by controlling the start of the exhaust component (13), the air inside the ventilation cylinder (12) is discharged to the outside through the exhaust pipe. The air flow path is from the ventilation slot (19) to the upper space, thereby creating a negative pressure environment inside the ventilation cylinder (12). Then, during the movement, the suction force will cause long debris to enter the interior of the ventilation cylinder (12). If the debris does not adhere tightly to the workpiece, the suction force will help the long debris to detach from the workpiece surface.

[0112] Furthermore, since the ventilation slot (19) is opened near the center of the disc (18), after long debris is attracted into the interior of the ventilation duct (12), it will move towards the vicinity of the ventilation slot (19), which is beneficial for the first extrusion block (20) and the second extrusion block (22) to clamp and fix the long debris; then, by controlling the electromagnet (21) to generate magnetism, under the attraction of the electromagnet (21), the second extrusion block (22) will move towards the first extrusion block (20), and then after the first extrusion block (20) and the second extrusion block (22) come into contact, they will squeeze and fix the attracted debris;

[0113] After the first extrusion block (20) and the second extrusion block (22) have fixed the long chip, the two pushers (17) are started to work, so that the two pushers (17) drive the disc (18) to move upward. The disc (18) drives the first extrusion block (20) and the second extrusion block (22) to move upward, thereby driving the long chip after clamping and fixing to move upward a certain distance. On the one hand, it is beneficial to use the pulling force generated when the first extrusion block (20) and the second extrusion block (22) move upward to pull the long chip, so as to help the long chip separate from the workpiece. On the other hand, when the first extrusion block (20) and the second extrusion block (22) move upward, if the chip is long, this operation helps to make it tend to be straight, which facilitates subsequent winding and storage.

[0114] After fixing, the second motor (14) is started. The second motor (14) drives the rotating column (15) to rotate. The rotating column (15) drives the ring (16) to rotate. The ring (16) drives the disc (18) to rotate through two pushers (17). The disc (18) drives the first extrusion block (20) to rotate. Because the first extrusion block (20) and the second extrusion block (22) are close together under the action of the electromagnet (21), the rotation of the first extrusion block (20) will trigger the second extrusion block (22) to rotate together. This process helps to effectively wind and gather long debris. It is beneficial to pull the long debris by the pulling force generated during the winding process, so as to make the long debris separate from the surface of the workpiece.

[0115] As an optional embodiment, the exhaust component (13) can be a negative pressure fan or a negative pressure pump.

[0116] As an optional embodiment, the pusher (17) can be a hydraulic rod or an electric telescopic rod.

[0117] As a technical optimization of the present invention, it also includes:

[0118] Two vertical columns (23) are fixedly and symmetrically installed on the outer wall of the rotating column (15);

[0119] Two downward grooves (24) are both opened at the top edge of the disk (18);

[0120] There are two sliding seats (25), which are fixedly connected to the two vertical columns (23) respectively, and the two sliding seats (25) are slidably connected to the inside of the two sliding grooves (24);

[0121] A slot (26) is formed on the side of the sliding seat (25) facing the first extrusion block (20);

[0122] The slitting blade (27) is fixedly installed inside the slot (26) by an elastic element (271);

[0123] In specific implementation, as mentioned in the above embodiment, the long debris is collected by the first extrusion block (20) in conjunction with the second extrusion block (22). However, after collection, the long debris is difficult to handle. If it needs to be collected manually, it may still cause scratches to the human body.

[0124] Therefore, when the pusher (17) drives the first extrusion block (20) upward through the disc (18), relative movement will occur between the sliding seat (25) and the sliding groove (24). Since the sliding seat (25) is fixed by the vertical column (23), the position of the sliding seat (25) remains unchanged. As the disc (18) continues to rise, the blade position of the slitting cutter (27) will move down to the first extrusion block (20) and the second extrusion block (22). After the slitting cutter (27) slides out from the inside of the sliding groove (24), the elastic element (271) will release the elastic force to push the slitting cutter (27) to slide out from the inside of the slot (26). At the same time, the blade can cut the long debris that has been wrapped between the first and second extrusion blocks (22). The additional force provided by the elastic element (271) helps the slitting cutter (27) to cut the debris more effectively, thereby promoting the efficient disposal of debris and making it easier to quickly divide the debris into small segments.

[0125] Repeat the above steps until the debris is divided into multiple small pieces. Then, the electromagnet (21) is de-energized and demagnetized, and the second extrusion block (22) will automatically fall back to its original position under the action of gravity. Furthermore, the pusher (17) will push each part back to its original position, which will facilitate the subsequent work.

[0126] As a technical optimization of the present invention, it also includes:

[0127] A gasket (28) is fixedly installed on the back of the slitting blade (27);

[0128] A hydraulic push rod (29) is fixedly installed inside the slot (26);

[0129] In specific implementation, as mentioned in the above embodiments, the debris is cut off by setting the additional action provided by the elastic element (271). However, if the cutting is only done by the force of the elastic element (271), there may be a situation where it is difficult to cut off.

[0130] Therefore, after the elastic element (271) releases its elastic force onto the long debris, the hydraulic push rod (29) is activated again. The hydraulic push rod (29) extends and contacts the pad (28), ultimately pushing the slitting blade (27) to cut the debris. On the one hand, the hydraulic push rod (29) pushes the slitting blade (27) to cut the mark again, which is beneficial for cutting off the uncut debris. On the other hand, the hydraulic push rod (29) pushes the slitting blade (27), causing the hydraulic push rod (29) to restrict the slitting blade. (27) The compressed elastic element (271) is pushed out of place, making it difficult to cut. After the slitting knife (27) is limited, the pusher (17) can drive the disc (18) to move up and down slightly, thereby driving the first extrusion block (20) to move up and down in conjunction with the second extrusion block (22), so that the slitting knife (27) can cut long debris in a cycle. The cutting mark is always the trajectory of the elastic element (271) pushing the slitting knife (27) to cut long debris, which is conducive to cutting the debris faster.

[0131] As a technical optimization of the present invention, it also includes:

[0132] A horizontal column (30) is fixedly installed on the inner wall of the ventilation duct (12);

[0133] The slide (31) is slidably connected to the cross column (30) and slidably connected to the outer wall of the disk (18);

[0134] The roller (32) is rotatably connected to the side wall of the slide (31) via a support plate;

[0135] In specific implementation, as mentioned in the above embodiment, the long debris is fixed and rolled up by the first extrusion block (20) and the second extrusion block (22). However, when the long debris is rolled up, the long debris may deviate from its position, resulting in poor rolling effect.

[0136] Therefore, after the first and second circular blocks move upward to the designated position, the roller (32) is placed outside the first extrusion block (20) and the second extrusion block (22). In this way, when the first extrusion block (20) and the second extrusion block (22) perform the winding operation on the long debris, the long debris will come into contact with the outer wall of the stationary roller (32). Because the roller (32) has the ability to rotate on its own, this will help reduce the frictional resistance generated between the long debris and the roller (32). Furthermore, thanks to this physical constraint of the roller (32), the long debris cannot deflect outward, and the long debris can be more smoothly wound and collected by the first extrusion block (20) and the second extrusion block (22).

[0137] It should be noted again that because the slide (31) is slidably connected to the disc (18), the slide (31) will also move upward as the disc moves upward. Also, because the horizontal column (30) is slidably connected to the slide (31), the slide (31) can slide vertically on the horizontal column (30), which is beneficial for adapting to the movement trajectory of the slide (31).

[0138] As a technical optimization of the present invention: the driving mechanism includes:

[0139] Four connecting plates (33) are fixedly installed on the top of the base frame (1);

[0140] The third motor (34) is fixedly mounted on the side wall of one of the connecting plates (33);

[0141] The second threaded rod (35) is fixedly installed on the output shaft end of the third motor (34), and the threaded rod is rotatably connected to a connecting plate (33), and the reciprocating seat (2) is threadedly connected to the second threaded rod (35);

[0142] The limiting rod (36) is fixedly installed between the other two connecting plates (33), and the reciprocating seat (2) is slidably connected to the limiting rod (36);

[0143] In practice, the third motor (34) drives the second threaded rod (35) to rotate. Under the action of the limit rod (36), the second threaded rod (35) drives the reciprocating seat (2) to move, thereby driving the cutting assembly to perform cutting.

[0144] like Figure 1 The method for controlling a turning device for machining a machine tool crossbeam includes the following steps:

[0150] The controller sends the second control information to the electromagnet (21) to control the electromagnet (21) to be energized and generate magnetism, so as to attract the second extrusion block (22) to move upward and fit with the first extrusion block (20).

[0155] Working principle of this invention:

[0156] The machine tool beam to be processed is placed on the support mechanism for limiting and fixing. Then the turning mechanism is adjusted to a suitable height, and the drive mechanism is started. The reciprocating seat (2) is moved by the drive mechanism, and the reciprocating seat (2) drives the turning mechanism to start, so that the turning mechanism can mill the target workpiece during the movement to achieve the expected processing shape.

[0157] During this process, the monitoring unit monitors the chips generated during turning in real time. When the monitoring unit detects that the chips generated during milling exceed the predetermined length, it controls the coiling and gathering component to start working. The coiling and gathering component first forms a negative pressure space, which facilitates the adsorption of long chips using suction. This allows the long chips to enter the interior of the coiling and gathering component. If the long chips are still adhered to the workpiece, the suction force guides the chips with weaker adhesion to detach from the workpiece surface. This helps reduce the occurrence of long chips adhering to the workpiece and adversely affecting the final shape shaping of the workpiece. If long chips adhere tightly to the workpiece, it is difficult to detach them using adsorption. In this case, the coiling and gathering assembly first fixes the end of the long chip and then rotates to coil it up. This coiling helps prevent the chips from returning to the workpiece and affecting the processing, and also helps prevent the chips from causing scratches to the operator. Furthermore, the pulling force generated during the coiling process applies force to the closely adhered long chips, which helps to quickly separate them from the workpiece and effectively avoids the problem of chips adhering to the workpiece and being difficult to remove.

[0158] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
