Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] The following describes in detail the specific implementation of the present invention with reference to specific embodiments.

[0031] See Figures 1 to 4 , a universal rotary fixture for a wire cutting machine tool, comprising:

[0032] Machine tool 1;

[0033] Cooling unit 2, installed inside the machine tool 1, for cooling the workpiece;

[0034] Fixing unit 5, rotatably connected inside the machine tool 1, for fixing the workpiece;

[0035] Moving unit 3, slidably connected inside the machine tool 1, connected to the fixing unit 5, for adjusting the position of the fixing unit 5;

[0036] Rotating unit 4, opened on the inner wall of the machine tool 1, slidably connected to the moving unit 3, for cooperating with the moving unit 3 to realize the rotation of the fixing unit 5;

[0037] Purification unit 7, rotatably connected to the fixing unit 5, for cooperating with the fixing unit 5 to realize the cleaning of the cutting fluid in the cooling unit 2.

[0038] In an embodiment of the present invention, when cutting a workpiece, the fixing unit 5 is used to fix the irregular workpiece, and both the workpiece and the cutting device can be cooled and chip removed under the action of the cooling unit 2. When it is necessary to adjust the cutting angle of the workpiece, by setting the moving unit 3 and the rotating unit 4, not only can the processing angle of the workpiece be adjusted in cooperation with the moving unit 3 and the rotating unit 4, but also the workpiece can be moved to the end position of the machine tool 1, which has the characteristics of convenient adjustment and easy processing.

[0039] During the process of clamping or disassembling the workpiece, by rotating the fixing unit 5, the fixing unit 5 can adapt to workpieces of different specifications, and during the rotation of the fixing unit 5, the purifying unit 7 can automatically remove the chips in the cutting fluid in cooperation with the fixing unit 5, so as to keep the normal operation of the machine tool and extend the service life of the equipment.

[0040] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the cooling unit 2 includes:

[0041] A cooling pool 21 is opened inside the machine tool 1, and a water pump 23 is installed inside.

[0042] A cooling pipe 22, one end of which is connected to the output end of the water pump 23, and the other end is connected to the inside of the machine tool 1.

[0043] In this embodiment, when cutting the workpiece, the fixing unit 5 is used to fix the workpiece, so that the wire cutting machine performs wire cutting on the workpiece. Cutting fluid is added to the cooling pool 21, and the water pump 23 is turned on, so that the output end of the water pump 23 brings the cutting fluid in the machine tool 1 into the cooling pipe 22 and discharges from the other end of the cooling pipe 22 and flows onto the surface of the workpiece, thereby cooling the workpiece and the electrode wire during the cutting process to prevent the decline of processing accuracy or equipment damage caused by overheating. In addition, the cutting fluid can also help remove the heat and chips generated during the processing, and can keep the normal operation of the machine tool and extend the service life of the equipment.

[0044] The cooling pipe 22 can also be connected to an external water source to facilitate continuous cooling and dust removal of the workpiece and the equipment.

[0045] In an embodiment of the present invention, as Figure 2 shown, the moving unit 3 includes:

[0046] A moving groove 31 is opened on the inner wall of the machine tool 1, and a sliding member 32 is slidably connected inside.

[0047] A driving rod 33 is rotatably connected to the machine tool 1, and the surface is connected to the sliding member 32 through a thread.

[0048] The driving member 34 is installed on the side of the machine tool 1, and the driving rod 33 is connected to the output end of the driving member 34;

[0049] The support frame 35 is rotatably connected to the side of the sliding member 32, and the fixing unit 5 is installed on the support frame 35.

[0050] In this embodiment, when the driving member 34 is turned on, the output end of the driving member 34 can drive the sliding member 32 to slide in the moving groove 31 through the driving rod 33. Thus, the sliding member 32 will drive the fixing unit 5 on its surface to slide synchronously through the support frame 35, and then the position of the workpiece on the fixing unit 5 can be adjusted, improving the cutting accuracy. The driving member 34 can be a motor or a pneumatic motor.

[0051] In an embodiment of the present invention, as Figure 3 and Figure 4 shown, the fixing unit 5 includes:

[0052] The device cylinder 51 is fixed on the support frame 35;

[0053] The support rod 52, one end is connected to the center of the device cylinder 51, and the other end is fixed with a support 53;

[0054] The rotating ring 521 is rotatably connected to the surface of the support rod 52, and eight groups of fixing rods 54 are fixed on the side;

[0055] The sliding rod 55 is slidably connected inside each group of fixing rods 54;

[0056] The octagonal frame 57 is fixed on the surface of the support rod 52 through the radial frame 58;

[0057] The rotating rod 59 is fixed on the sliding rod 55, and the surface is slidably connected to the surface of the octagonal frame 57;

[0058] The elastic member 56 is connected between the rotating rod 59 and the fixing rod 54, and the elastic member 56 can be a spring or an elastic rubber.

[0059] In this embodiment, when fixing the workpiece, the fixture 6 is pulled outwards, so that the fixture 6 pulls the sliding rod 55 to slide outwards in the fixed rod 54 through the rotating rod 59. When the rotating rod 59 slides outwards, it will stretch the elastic member 56 until the workpiece can be placed on the surface of the support 53. At this time, the fixture 6 is released, and the rotating rod 59 will push the sliding rod 55 to slide inwards in the fixed rod 54 in the reverse direction under the elastic force of the elastic member 56 until the fixture 6 contacts the surface of the workpiece. Since there are eight groups of fixtures 6, and the corresponding fixed rods 54 and sliding rods 55 of each group of fixtures 6 are independent, the reset positions of each group of fixtures 6 can also be different. Therefore, different specifications of workpieces can be fixed through the cooperation of multiple groups of fixtures 6, improving the application range of the equipment.

[0060] In an embodiment of the present invention, as Figure 4 shown, the fixture 6 includes:

[0061] A rotating shaft 61 connected to the end of the rotating rod 59;

[0062] An arc-shaped frame 62 rotatably fixed on the surface of the rotating shaft 61.

[0063] In this embodiment, when the rotating rod 59 pushes the sliding rod 55 to slide inwards in the fixed rod 54 in the reverse direction under the elastic force of the elastic member 56, the rotating rod 59 will drive the arc-shaped frame 62 to slide synchronously in the reverse direction through the rotating shaft 61 until the arc-shaped frame 62 contacts the surface of the workpiece. When the surface of the workpiece is irregular, since the arc-shaped frame 62 is rotatably fixed on the surface of the rotating shaft 61, the arc-shaped frame 62 can rotate freely on the rotating shaft 61. Therefore, both ends of the arc-shaped frame 62 can be in close contact with the workpiece, so that the fixture 6 can fix the irregular workpiece, further improving the application range of the equipment.

[0064] In an embodiment of the present invention, as Figure 2 shown, the rotating unit 4 includes:

[0065] A first chute 41 opened on the machine tool 1;

[0066] A second chute 42 opened on the machine tool 1, and the ends of the first chute 41 and the second chute 42 are connected by two groups of inclined chutes 43;

[0067] A sliding column 44 fixed on the side surface of the support frame 35, and the surface is slidably connected inside the first chute 41, the second chute 42 and the inclined chute 43. The rotation radius of the support frame 35 driving the sliding column 44 to rotate is equal to the vertical height of the inclined chute 43.

[0068] In this embodiment, when it is necessary to adjust the cutting angle of the workpiece, by turning on the driving member 34, the sliding member 32 drives the fixing unit 5 on its surface to slide through the support frame 35, and then the fixing unit 5 can drive the workpiece to move. As Figure 2 shown, in the initial state, the sliding column 44 is at the bottommost position of the inclined groove 43. When the sliding member 32 drives the sliding column 44 to slide through the support frame 35, at this time, the sliding column 44 will slide into the first sliding groove 41 (or the second sliding groove 42) through the inclined groove 43.

[0069] When the sliding column 44 slides into the inclined groove 43, at this time, the support frame 35 will rotate on the side of the sliding member 32 under the action of the sliding column 44 and the inclined groove 43. Until the sliding column 44 slides into the first sliding groove 41 (or the second sliding groove 42), at this time, the sliding column 44 and the sliding member 32 are at the same height, so the support frame 35 rotates from the vertical state to the horizontal state. When the support frame 35 rotates, it will drive the workpiece to rotate synchronously through the fixing unit 5, so that the workpiece will rotate from the horizontal state to the vertical state, and thus the processing angle of the workpiece can be freely adjusted. And the support frame 35 slides from the central position of the machine tool 1 to the end position, so the fixing unit 5 synchronously drives the workpiece to move to the end position of the machine tool 1. By setting the rotating unit 4, not only can the processing angle of the workpiece be adjusted, but also the workpiece can be moved to the end position of the machine tool 1, which is more convenient for processing the workpiece.

[0070] In an embodiment of the present invention, as Figure 3 shown, the purification unit 7 includes:

[0071] A filter disk 71, fixed inside the device cylinder 51, and filter holes 72 penetrating the device cylinder 51 are provided on the filter disk 71;

[0072] A scraper 73, with one end fixed on the surface of the rotating rod 59 and the side surface slidably connected to the surface of the filter disk 71, is used to remove the debris on the surface of the filter disk 71;

[0073] A positioning groove 711, opened at the top corner positions of the octagonal frame 57 and the filter disk 71, is engaged with the surface of the rotating rod 59.

[0074] In this embodiment, during the cutting of the workpiece, the cutting fluid flowing out of the cooling pipe 22 will flow into the inside of the device cylinder 51 after cooling and dust removal of the workpiece. At this time, the cutting fluid in the device cylinder 51 will flow into the cooling pool 21 through the filter holes 72 for recycling, and the debris in the cutting fluid will be adsorbed on the surface of the filter disk 71.

[0075] During the clamping or disassembling of the workpiece, the rotating rod 59 needs to be rotated. When the rotating rod 59 slides on the surface of the octagonal frame 57, it will simultaneously slide on the surface of the filter disc 71. At the same time, the rotating rod 59 will drive the scraping plate 73 to slide on the surface of the filter disc 71, so that the scraping plate 73 can scrape the debris adsorbed on the surface of the filter disc 71 into the gap between the device cylinder 51 and the filter disc 71, thereby clearing the debris on the surface of the filter disc 71, improving the filtering effect of the filter disc 71 on the cutting fluid, and facilitating the continuous processing of the workpiece.

[0076] Further, a discharge valve can be installed at the bottom of the device cylinder 51. By regularly opening the discharge valve, the debris collected inside the device cylinder 51 can be cleared.

[0077] A wire cutting machine includes a universal rotating fixture for a wire cutting machine tool and also includes a wire feeding unit 8. The wire feeding unit 8 is slidably connected to the side of the machine tool 1. The wire feeding unit 8 includes:

[0078] A wire feeding seat 81, fixed to the side of the machine tool (1), with a slider 82 slidably connected to its surface;

[0079] A lead screw 83, rotatably connected inside the wire feeding seat 81, and its surface is connected to the slider 82 through a thread;

[0080] A wire feeding wheel 84, rotatably connected to the slider 82, and an electric cutting molybdenum wire 85 is wound around the surfaces of the two wire feeding wheels 84.

[0081] In this embodiment, the end of the lead screw 83 is connected to a servo motor that drives it to rotate. When the servo motor is turned on, the lead screw 83 drives the slider 82 to slide on the wire feeding seat 81, so that the wire feeding seat 81 can drive the electric cutting molybdenum wire 85 to move through the wire feeding wheel 84, and thus the electric cutting molybdenum wire 85 can perform electric cutting on the workpiece. In other embodiments, the wire feeding seat 81 and the lead screw 83 can also be vertically installed, so that the wire feeding wheel 84 drives the electric cutting molybdenum wire 85 to perform vertical wire feeding, which is not limited to this.

[0082] The working principle of the present invention is as follows: When it is necessary to adjust the cutting angle of the workpiece, the driving member 34 is turned on, so that the sliding member 32 drives the fixing unit 5 on its surface to slide through the support frame 35, and then the fixing unit 5 can drive the workpiece to move. When the sliding column 44 slides into the inclined groove 43, at this time, the support frame 35 will rotate on the side of the sliding member 32 under the action of the sliding column 44 and the inclined groove 43. Until the sliding column 44 slides into the first sliding groove 41 (or the second sliding groove 42), at this time, the workpiece will rotate from the horizontal state to the vertical state, and the fixing unit 5 drives the workpiece to move to the end position of the machine tool 1. By setting the rotating unit 4, not only can the processing angle of the workpiece be adjusted, but also the workpiece can be moved to the end position of the machine tool 1, which has the characteristics of convenient adjustment and easy processing.

[0083] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection, an electrical connection or a communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0084] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
