Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric spark cutting, in particular to a roller moving device. BACKGROUND

[0002] Electric spark processing is a processing method for reasonably utilizing electric corrosion. The method removes materials through pulse spark discharge between a tool electrode and a workpiece motor, and then completes the processing of the shape of the material. In the electric spark wire cutting process, the electrode wire is used as the tool electrode, and the workpiece to be cut is used as the workpiece electrode. Under the excitation of the pulse power supply, spark discharge occurs, heat is generated to melt or even vaporize the workpiece, and the explosion generated in this process throws the removed material away from the workpiece, which is carried away by the working fluid and filtered.

[0003] Electric spark wire cutting adopts electric processing principle, and can process many materials that are difficult to process by ordinary processing methods, such as PCD materials with high hardness, materials with high melting point and high energy consumption by ordinary processing methods, and materials with high brittleness that are difficult to process by mechanical means. With the characteristics of strong applicability, high precision and low cost, it has been widely used in the fields of automobile, aviation, machine tool production, etc.

[0004] In the prior art, the movement of the roller is mainly realized by the following two ways during electric spark processing:

[0005] In one way, a translation table is arranged between the roller support and the base, and the relative movement of the roller and the base is driven by the movement of the translation table. However, the translation table is often large in size and needs to occupy a large space, and when the roller is moved by the translation table, the mass of the object to be moved is increased, resulting in high cost. In addition, the limit position of the translation table often does not coincide with the limit position of the lead screw, increasing the control and operation difficulty.

[0006] In another way, the roller is connected with the lead screw through a synchronous belt, so that the roller can move along the direction of the lead screw while rotating. This way, the roller needs to be turned on every time the roller moves, and when there is a wire on the roller, it is easy to cause safety accidents. In addition, when the wire is fixed at one end of the roller due to wire breakage or other reasons, moving the roller by rotating it will also cause the wire to wind. SUMMARY

[0047] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, further detailed description of the embodiments of the present application is given below in conjunction with the drawings. Here, the illustrative embodiments of the present application and the description thereof are used to explain the present application, but are not used as a limitation of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0048] Figure 1 and Figure 2 is a schematic diagram of the arrangement of the wire on the roller provided by some embodiments of the present application, as shown in Figure 1 When normal processing is performed, the wire is uniformly wound on the roller 101, one end of the wire is fixed on the roller, the other end of the wire is fixed between the roller 101 and the wire clamping device 200, and the wire is clamped by the roller 101 and the wire clamping device 200. The wire extends from the position indicated by the triangle in the figure, passes through the upper arm and the lower arm, and moves through the rotation of the roller 101 to perform electric spark cutting. With the rotation of the roller 101, the wire used for cutting also moves from one end of the roller 101 to the other end. To ensure that the position of the wire for cutting does not change, and at the same time to ensure that the wire is uniformly wound on the roller, the roller 101 moves left and right while rotating.

[0049] In actual production and processing, on the one hand, the electrode wire may be broken sometimes, and on the other hand, the wire may need to be actively broken to make a hole. As shown in Figure 2 After the wire is broken each time, the length of the wire will be reduced by a certain length, and the interval of the wire does not change. Since the fixed position of the wire on the roller does not change, the wire on the side of the wire clamping device 200 will become less and less. Since the position of the lower arm does not change, that is, the spatial position indicated by the triangle in the figure does not change, the roller assembly needs to be moved so that the position of the wire extending out is aligned with the lower arm. After the wire is broken each time, the distance between the lower arm and the wire clamping device 200 will become farther and farther.

[0050] In the prior art, the movement of the roller is mainly realized by the following two ways:

[0051] In one way, a translation table is arranged between the roller support and the base, and the relative movement between the roller and the base is driven by the movement of the translation table. However, the translation table is usually large in size and needs to occupy a large space, and when the roller is driven to move by the translation table, the mass of the object to be moved is increased, resulting in high cost. In addition, the limit position of the translation table is usually not coincided with the limit position of the lead screw, increasing the control and operation difficulty.

[0052] In another way, the roller 101 is connected with the lead screw through a synchronous belt, so that the roller can move along the direction of the lead screw while rotating. In this way, the roller needs to be started to rotate each time the roller moves, however, each time the wire is disconnected and the wire is rethreaded through the lower arm, the position of the lower arm is farther away from the wire clamping device 200, which causes the misalignment of the two and the failure to clamp the wire. In addition, due to the limited length of the wire, the translation cannot be realized by rotating the roller. In addition, when the wire is fixed at one end of the roller due to wire disconnection and other reasons, the wire will be wound if the roller is translated by rotating, which is easy to cause safety accidents.

[0053] To solve the above problems, the present application provides a roller moving device which realizes the translation of the roller without rotating the roller through a simple structure, thereby compensating for the position change caused by the change of the wire length.

[0054] Figures 3-7 is a structural schematic diagram of the roller moving device provided by an embodiment of the present application, as Figures 3-7 shown, the roller moving device provided by the present application comprises a roller 101, a synchronous belt 102, a pulley 103, a lead screw 104, a rotatable nut 105, a first gear 106, a second gear 107 and a first motor 108.

[0055] Among them, the pulley 103 is connected with the roller 101 through the synchronous belt 102;

[0056] Specifically, as Figure 4 shown, the synchronous belt 102 can be in contact with the bearing at one end of the roller 101, and the rotation of the bearing drives the synchronous belt 102 to rotate, thereby further driving the pulley 103 to rotate. The rotation direction of the bearing is the same as that of the pulley 103, and the pulley 103 will only rotate with the roller 101 and will not move relatively. In addition, other elements such as gears, rotating wheels with protrusions on both sides, etc. can be added on the bearing according to the type of the synchronous belt 102 to realize meshing with the synchronous belt 102, increase the friction between the synchronous belt 102, and limit the synchronous belt 102.

[0057] In an embodiment, the synchronous belt 102 can have a rough surface to drive the pulley 103 to rotate by friction; in another embodiment, the synchronous belt 102 can also be a toothed belt with a toothed surface, and the pulley 103 is a gear to mesh with the synchronous belt 102 to rotate.

[0058] In an embodiment, as shown in Figure 3 the drum moving device provided by the present application further comprises a second motor 109 for driving the drum 101 to rotate, which is fixedly connected with the drum 101.

[0059] Specifically, the second motor 109 is arranged on the side of the drum 101 opposite to the synchronous belt 102, and the second motor 109 is a rotary motor. A gear can be arranged on the bearing of the drum 101 and the rotating shaft of the second motor 109 respectively, and the two gears are engaged with each other, so that the drum 101 is driven to rotate by the rotation of the second motor 109, and the rotation speed ratio is adjusted by the size of the two gears; the second motor can also be directly connected coaxially with the drum 101, so that the drum 101 is driven to rotate by the rotation of the second motor, but the present application is not limited thereto.

[0060] The lead screw 104 is fixedly connected with the pulley 103;

[0061] Specifically, the lead screw 104 is fixedly connected with the pulley 103 and rotates with the pulley 103, and the lead screw 104 also does not move relative to the drum 101. The lead screw 104 can be fixedly connected with the pulley 103 by screws, or can be welded with the pulley 103, but the present application is not limited thereto.

[0062] The rotatable nut 105 is sleeved with the lead screw 104, and when the rotatable nut 105 rotates, the lead screw 104 which does not rotate moves along the axial direction;

[0063] Specifically, the rotatable nut 105 can only rotate and does not move left and right. As shown in Figures 5-6 and Figure 8As shown, the surface of the screw rod 104 and the inner side of the rotatable nut 105 are provided with threads, the rotatable nut 105 is sleeved on the screw rod 104, and the threads on the inner side of the rotatable nut 105 and the threads on the surface of the screw rod 104 are engaged with each other. In the normal working state, the rotation of the drum 101 drives the rotation of the screw rod 104, and the rotatable nut 105 is locked and does not rotate. At this time, the screw rod 104 and the rotatable nut 105 rotate relative to each other, and under the action of the threads, the screw rod 104 and the rotatable nut 105 move relative to each other. Since the rotatable nut 105 is fixed, the screw rod 104 drives the drum 101 to move; when it is desired that the drum 101 does not rotate and moves, the drum 101 is locked, and the screw rod 104 connected to the drum 101 step by step also does not rotate. At this time, the rotatable nut 105 rotates, and under the action of the threads, the screw rod 104 and the rotatable nut 105 move relative to each other. Since the rotatable nut 105 is fixed, the screw rod 104 drives the drum 101 to move.

[0064] In an embodiment, as shown in Figure 8 The drum moving device provided by the application further comprises a ball 110 arranged between the rotatable nut 105 and the screw rod 104. By arranging the ball 110 between the rotatable nut 105 and the screw rod 104, the rotation between the rotatable nut 105 and the screw rod 104 can be smoother, and the screw rod 104 or the rotatable nut 105 from being stuck due to rust or the like, thereby causing the drum 101 to be unable to move.

[0065] The first gear 106 is fixedly connected with the rotatable nut 105 and coaxially rotates with the rotatable nut 105;

[0066] Specifically, as shown in Figure 5 and Figure 6 The first gear 106 is sleeved on the outer side of the rotatable nut 105, and the shaft center is penetrated by the screw rod 104. When the first gear 106 rotates, the rotatable nut 105 is driven to rotate, so that the screw rod 104 moves relatively. The first gear 106 and the rotatable nut 105 can be fixedly connected by screws, or can be connected by other means, for example, welding, etc. The specific connection mode of the first gear 106 and the rotatable nut 105 is not limited in the application.

[0067] The second gear 107 is engaged with the first gear 106;

[0068] Specifically, as shown in Figure 7As shown, the second gear 107 is engaged with the first gear 106, when the second gear 107 rotates, the first gear 106 can be driven to rotate; when the second gear 107 is locked, the first gear 106 engaged with the second gear 107 is also locked, and the first gear 106 and the rotatable nut 105 connected with the first gear 106 cannot rotate. The rotation speed ratio of the first gear 106 and the second gear 107 can be adjusted by adjusting the number of teeth contained in the first gear 106 and the second gear 107.

[0069] The first motor 108 is used to drive the second gear 107, and the second gear 107 is fixedly connected with the first motor 108 and is locked when the roller 101 rotates.

[0070] Specifically, the first motor 108 is a rotating motor, and the first motor 108 only rotates and does not move along the screw direction. When the first motor 108 is locked, the second gear 107 fixedly connected with the first motor 108 is also locked, and the first gear 106 engaged with the second gear 107 and the rotatable nut 105 fixedly connected with the first gear 106 are also locked and cannot rotate. When the first motor 108 rotates, the second gear 107 fixedly connected with the first motor 108 is driven to rotate, so that the first gear 106 and the rotatable nut 105 also rotate.

[0071] On the basis of the above-mentioned embodiments, further, as shown, Figure 3 The roller moving device provided by the application further comprises a roller connecting piece 111 and a roller base 112; the roller connecting piece 111 is connected with the roller 101; and the roller base 112 is fixedly connected with the roller connecting piece 111.

[0072] Specifically, the roller connecting piece 111 is connected with the bearing of the roller 101, and is used to provide support for the roller 101, and the roller 101 and the roller connecting piece 111 do not relatively move. The roller base 112 is fixedly connected with the roller connecting piece 111, and the roller 101 and the roller base 112 only relatively rotate and do not relatively move.

[0073] On the basis of the above-mentioned embodiments, further, as shown, Figure 3 The roller moving device provided by the application further comprises a whole base 113, and the screw 104, the first gear 106, the second gear 107 and the first motor 108 are arranged in the whole base 113.

[0074] Specifically, the whole base 113 is the base of the whole electric spark cutting device, and is kept stationary during the whole production process. When the roller 101 moves, the whole base 113 relatively displaces with the roller 101.

[0075] In an embodiment, the integral base 113 is provided with a sliding rail 114; the drum base 112 is clamped on the sliding rail 114 and moves along the sliding rail 114. By providing the sliding rail 114, the drum base 112 is supported by the integral base 113 and can move freely along the sliding rail 114 to generate relative displacement and move the drum 101 to the desired position.

[0076] In an embodiment, as shown in Figure 5 the drum moving device provided by the application further comprises a mounting seat 115; the rotatable nut 105 is mounted on the mounting seat 115, and the mounting seat 115 is fixed on the integral base 113. By providing the mounting seat 115, the positions of the first gear 106 and the rotatable nut 105 are fixed to ensure that the rotatable nut 105 can only rotate and cannot move.

[0077] For example, as shown in Figure 9 a ball bearing 116 can be provided outside the first gear 106, the outer bearing 1161 of the ball bearing 116 is fixedly connected with the mounting seat 115, and the inner bearing 1162 is fixedly connected with the first gear 106. Since the mounting seat 116 is fixed on the integral base 113 and the outer bearing 1161 of the ball bearing 116 is fixedly connected with the mounting seat 115, the position of the ball bearing 116 is also fixed, the outer bearing 1161 of the ball bearing cannot move or rotate, and the inner bearing 1162 can only rotate and cannot move. Since the first gear 106 is connected with the inner bearing 1162 of the ball bearing 116, the first gear 106 can also only rotate and cannot move, so that the rotatable nut 105 fixedly connected with the first gear 106 can also only rotate and cannot move. In addition, a pressing plate 117 and a locking nut 118 can be respectively provided on both sides of the ball bearing 116 to further fix the position of the ball bearing 116.

[0078] The above structure is only used for exemplary description, and the mounting seat can be realized by any structure that can fix the rotatable nut 105 so that it can only rotate and cannot move, for example, a baffle is provided on the rotatable nut, and the specific structure of the mounting seat is not limited in the application.

[0079] In an embodiment, a first laser emitter can be provided below the drum base 112, and a first sensor can be provided on the integral base 113, so that the first laser emitter and the first sensor are aligned when the drum 101 clamps the wire. At this time, if the first sensor receives the laser emitted by the first laser emitter, it means that the drum 101 has moved to the preset wire clamping position, at which time the drum can be stopped and the wire can be clamped.

[0080] In an embodiment, a second laser emitter can be arranged below the drum base 112, and a second sensor can be arranged on the integral base 113, so that the second laser emitter is aligned with the second sensor when the drum 101 is rolling and working normally. At this time, if the second sensor receives the laser emitted by the second laser emitter, it means that the drum 101 has moved to the position required for normal work, and the drum 101 can be started to perform electric spark cutting at this time.

[0081] The first laser emitter and the second laser emitter can be arranged on the drum base 112 at the same time, and the first sensor and the second sensor can be arranged correspondingly on the integral base 113. At this time, the first laser emitter and the second laser emitter should emit different lasers, and the first sensor and the second sensor should receive and sense corresponding types of lasers. In addition, the positions of the laser emitters and the corresponding sensors can also be interchanged.

[0082] In an embodiment, a third laser emitter can also be arranged on the side of the drum connecting piece 111 away from the drum 101, and a distance measuring sensor can be arranged on a plane fixed on the integral base 113 and not subject to movement, to receive the laser emitted by the third laser emitter and measure the distance between itself and the drum connecting piece 111. When the distance between the distance measuring sensor and the drum connecting piece 111 is equal to a preset distance, the movement of the drum 101 is stopped, and the wire clamping or the rotation of the drum 101 for work is started. The distance measuring sensor can also be arranged to detect multiple preset distances, and the drum 101 is stopped when a preset distance is reached.

[0083] Arranging the laser emitters on the drum connecting piece or the drum base can prevent the laser emitters from affecting the dynamic balance of the drum, and keep the direction of the laser emitted by the laser emitters unchanged.

[0084] The drum moving device provided by the application comprises a drum, a synchronous belt, a pulley connected with the drum through the synchronous belt, a lead screw fixedly connected with the pulley, a rotatable nut which is sleeved with the lead screw and relatively moves with the lead screw when the lead screw rotates, a first gear fixedly connected with the rotatable nut and coaxially rotating with the rotatable nut, a second gear engaged with the first gear and driven to rotate, and a first motor fixedly connected with the second gear and locked when the drum rotates. The drum moving device provided by the application realizes two moving modes of the drum, i.e., moving while rotating and translating without rotating, has a simple structure, is easy to operate, does not affect the limit position of the lead screw, saves energy, and improves production efficiency.

[0085] The application principle of the drum moving device provided by the application will be described below.

[0086] When working normally, the first motor 108 is locked, and the second gear 107 fixedly connected with the first motor 108 is also locked, so that the first gear 106 and the rotatable nut 105 are locked and cannot rotate. At this time, the roller 101 rotates, thereby driving the synchronous belt 102 and the pulley 103 to rotate, and further driving the lead screw 104 to rotate. Since the rotatable nut 105 is sleeved with the lead screw 104, the rotatable nut 105 is locked and cannot rotate, so that the lead screw 104 moves relative to the rotatable nut 105 under the action of the thread while rotating relative to the rotatable nut 105. Since the rotatable nut 105 is fixed on the mounting seat 115, the position between the rotatable nut 105 and the overall base 113 does not change, and the lead screw 104 moves relative to the overall base 113, thereby driving the roller 101 to move.

[0087] When the roller 101 needs to be moved but the roller 101 is not desired to rotate, such as when the yarn is clamped or in other cases, the roller 101 is locked, thereby locking the synchronous belt 102 and the pulley 103 connected with the roller 101 through the synchronous belt. Since the pulley 103 is fixedly connected with the lead screw 104, the lead screw 104 cannot rotate. At this time, the first motor 108 rotates, thereby driving the second gear 107 fixedly connected with the first motor 108 to rotate, and further driving the first gear 106 engaged with the second gear 107 and the rotatable nut 105 fixedly connected with the first gear 106 to rotate. Since the lead screw 104 is locked and cannot rotate, the rotation of the rotatable nut 105 causes the rotatable nut 105 to rotate relative to the lead screw 104, and the rotatable nut 105 moves relative to the lead screw 104 under the action of the thread. Since the rotatable nut 105, the first gear 106, the second gear 107 and the first motor 108 are arranged in the overall base 113 and cannot move, when the rotatable nut 105 moves relative to the lead screw 104, in fact, the lead screw 104 moves, thereby driving the pulley 103, the synchronous belt 102 and the roller 101 to move. That is, the roller 101 can be moved without rotating, and since the movement of the roller 101 is driven by the lead screw 104, the situation that the limit position of the lead screw 104 does not match the limit position and affects the limit position of the movement does not occur. In addition, the movement does not introduce redundant structures, causing space waste or an increase in the moving weight, and the operation is simple, resource saving and work efficiency improving.

[0088] When the second motor 109 is arranged, the roller 101 can be locked by the second motor 109 being powered off, and other locking structures can also be arranged to lock the roller 101, and the specific way of locking the roller 101 is not limited in the application.
