Description

Technical Field

[0002] The EDM perforator is also called EDM puncher, EDM small hole machine, EDM fine hole discharge machine. Its working principle is to use a thin metal copper tube (electrode wire) that moves vertically up and down as an electrode to perform pulsed spark discharge to erode the metal of the workpiece. Since the electrode wire is easily worn out during the processing, it is necessary to replace the electrode wire in time.

[0003] In the prior art, the electrode wire is installed on the tool handle to form the tool handle electrode, and the tool handle electrode is stored in the tool magazine. When the electrode wire needs to be replaced, the tool handle is grabbed by a manipulator provided on the tool magazine and the tool handle electrode is sent to the spindle of the machine tool. However, due to the poor rigidity of the electrode wire and the long length of the electrode wire extending out of the tool handle, the electrode wire will vibrate violently during the movement of the manipulator, which not only increases the difficulty of assembling the electrode wire on the spindle, but also easily causes damage to the electrode wire. Summary of the invention

[0023] Preferably, a sensing module is also provided on the first base, and the sensing module is electrically connected to the control component. During the rotation of the cutter disc, the sensing module can sequentially face the multiple working positions and output a loading signal on the tool holder to the control component.

[0024] By adopting the above technical solution, the control component can grasp the loading status of the tool holder in real time, so as to accurately position the tool holder when changing the tool, thereby further improving the tool changing efficiency.

[0047] Embodiment 1:

[0048] See also Figure 1-3 As shown, a tool handle electrode replacement device is shown, which is used to replace the tool handle electrode 100 on the spindle. The tool handle electrode 100 includes a tool handle 1001 and an electrode wire 1002, and the replacement device includes a tool magazine 1, a tool changing mechanism 2 and a control component.

The control component (not shown in the figure) is a PLC controller, which is electrically connected to the tool magazine 1 and the tool changing mechanism 2 respectively, and is used to control the overall operation of the tool magazine 1 and the tool changing mechanism 2.

[0049] In this embodiment, combined with Figure 2 As shown, the tool magazine 1 includes a first base 11, a cutter disc 12 horizontally arranged on the first base 11 and capable of rotating around a vertical direction, a first driving module 13 for driving the cutter disc 12 to rotate, and a plurality of tool holders 14 spaced apart on the circumferential side of the cutter disc 12, a tool handle 1001 is installed on the tool holder 14, and an electrode wire 1002 is connected to the lower end of the tool handle 1001.

[0050] The first base 11 includes a suspension 111, a mandrel 112 connected to the lower end of the suspension 111, and a mounting plate 113 coaxially arranged at the lower end of the mandrel 112. The suspension 111 is used to be fixed to the machine tool, the mandrel 112 is inserted into the suspension 111, and a retaining spring (not shown in the figure) is arranged between the two. The cutter head 12 is rotatably sleeved on the mandrel 112 and is located above the mounting plate 113. The retaining spring can provide a buffer for the cutter head 12 to prevent the handle electrode 100 from having a rigid collision with the cutter head during the disassembly and replacement process, thereby causing damage to the electrode wire 1002.

[0051] A mounting groove 114 for accommodating the first drive module 13 is formed between the cutter disc 12 and the mounting disc 113, and a wiring groove 115 is provided in the core shaft 112, and the wiring groove 115 is connected to the mounting groove 114. The first drive module 13 is a combination structure of a motor and a reducer, and the line connected to the motor can be passed through the wiring groove 115 to prevent the line from interfering with the rotation of the cutter disc 12.

[0052] In this embodiment, the tool changing mechanism 2 includes a second base 21 arranged at the bottom of the tool disc 12, a tool changing seat 22 arranged on the second base 21 and movably movable along the direction from the center of the tool disc 12 to the tool holder 14, and a second driving module 23 for driving the tool changing seat 22 to move. A first clamp 24 and a second clamp 25 are arranged on the tool changing seat 22, and the first clamp 24 and the second clamp 25 are arranged up and down, and the second clamp 25 is slidable along the length direction of the electrode wire 1002. The tool changing mechanism 2 also includes a third driving module 26 for driving the second clamp 25 to slide.

[0053] In this way, the second clamp 25 can clamp the electrode wire 1002 and slide along the length direction of the electrode wire 1002 during the replacement process of the electrode wire 1002 to limit the electrode wire 1002, thereby avoiding the electrode wire 1002 from shaking; at the same time, the sliding second clamp 25 can dynamically limit the electrode wire 1002 to avoid a single position of the electrode wire 1002 continuously contacting the second clamp 25 and causing damage to the electrode wire 1002; and the second clamp 25 can also guide the electrode wire 1002 during its sliding process to prevent the electrode wire 1002 from being deflected, thereby facilitating the subsequent installation of the electrode wire 1002.

[0054] Among them, the second driving module 23 is a double-axis cylinder, and the tool changing seat 22 is arranged at the end of the piston rod of the double-axis cylinder; the third driving module 26 is a slide cylinder arranged on the tool changing seat 22, the first clamp 24 is arranged on the base of the slide cylinder, and the second clamp 25 is arranged on the slide of the slide cylinder; the first clamp 24 is a manipulator, which is driven by the fifth driving module 27 to realize opening and closing, and the fifth driving module 27 is a finger cylinder.

[0055] In this embodiment, the first clamping jaw 24 and the second clamping jaw 25 can be synchronously clamped on the tool handle 1001 and the electrode wire 1002 during the moving stroke of the tool changer 22. When the second clamping jaw 25 is clamped on the electrode wire 1002, the control component synchronously controls the second clamping jaw 25 to slide along the length direction of the electrode wire 1002. The second clamping jaw 25 can slide along the length direction of the electrode wire 1002 while clamping the electrode wire 1002, ensuring that the electrode wire 1002 can be limited by the second clamping jaw 25 throughout the moving stroke, and completely preventing the occurrence of the shaking phenomenon of the electrode wire 1002.

[0056] In this embodiment, combined with Figure 3As shown, the second clamping jaw 25 includes two claw bodies 251 that can be relatively opened and closed, and a fourth driving module 252 for driving the two claw bodies 251 to move. The fourth driving module 252 is also a finger cylinder. The two claw bodies 251 are respectively provided with notches 253 on one side close to each other. When the two claw bodies 251 are relatively closed, the two notches 253 enclose a slide groove 254 for the electrode wire 1002 to slide. The slide groove 254 can provide a sliding space for the electrode wire 1002 to prevent the electrode wire 1002 from being worn due to continuous relative friction with the second clamping jaw 25.

[0057] The two claws 251 are staggered along the length direction of the electrode wire 1002, and a limiting column 255 for resisting the other one is provided on one of the two claws 251. When the two claws 251 are relatively closed, the limiting column 255 can resist the claws 251 to prevent the two claws 251 from being over-closed and causing damage to the electrode wire 1002.

[0058] In this embodiment, combined with Figure 1 As shown, a plurality of tool changing stations 15 are arranged around the cutter disc 12 at intervals around the cutter disc 12 itself, and numbers 16 are respectively provided on the plurality of tool changing stations 15, and a tool holder 14 is respectively provided on each tool changing station 15. The plurality of tool changing stations 15 are numbered in the order of Arabic numerals, and tool holder electrodes 100 of various specifications can be respectively placed on the tool changing stations 15 with numbers 16. When replacing the tool holder electrode 100, the control component can locate the tool changing station 15 with the corresponding number 16 according to the specifications of the tool holder electrode 100 to be replaced, thereby effectively improving the tool changing efficiency.

[0059] The plurality of tool changing stations 15 include an initial position 151 and a plurality of working positions 152. The initial position 151 is numbered 16 as 0, and the plurality of working positions 152 are numbered 16 in the order of 1-n. The tool holder 14 arranged at the initial position 151 is unloaded, and the tool holder 14 arranged at the plurality of working positions 152 is fully loaded. The cutter disc 12 has an initial position and a plurality of working positions in its rotation stroke. When the cutter disc 12 is at the initial position, the first clamping jaw 24 and the second clamping jaw 25 face the initial position 151; when the cutter disc 12 is at the working position, the first clamping jaw 24 and the second clamping jaw 25 face any one of the plurality of working positions 152.

[0060] In this way, there can always be an unloaded tool holder 14 on the cutter disc 12 to load the old tool holder electrode 100. When the cutter disc 12 is in the initial position, the first clamping jaw 24 and the second clamping jaw 25 face the initial position 151 numbered 16 as 0, and then the old tool holder electrode 100 on the spindle can be directly disassembled and installed on the unloaded tool holder 14 at the initial position 151. Then, the cutter disc 12 can switch between the initial position and the working position during its rotation. The first clamping jaw 24 and the second clamping jaw 25 can quickly disassemble the old tool holder electrode 100 and install the new tool holder electrode 100 when the cutter disc 12 is in different positions, and the disassembly and replacement efficiency is high.

[0061] In this embodiment, combined again Figure 2 As shown, a sensing module 17 is also provided on the first base 11. The sensing module 17 is a laser sensing switch, which is electrically connected to the control component. The sensing module 17 can sequentially face the plurality of working positions 152 during the rotation of the cutter disc 12 and output a loading signal on the tool holder 14 to the control component. Through the sensing of the sensing module 17, the control component can grasp the loading status of the tool holder 14 in real time, so as to accurately position the tool holder 14 when changing the tool, thereby further improving the tool changing efficiency.

[0062] Embodiment 2:

[0063] This embodiment discloses a disassembly method of the tool holder electrode 100 disassembly device based on the embodiment 1, which is used to disassemble the tool holder electrode 100 on the spindle of a machine tool, and includes the following steps:

[0064] Step 1, the first driving module 13 drives the cutter head 12 to rotate and stops the cutter head 12 at the initial position, the tool changer 22 moves in a direction away from the second base 21 and passes through the initial position 151, and then the tool changer 22 reaches the side of the machine tool spindle, and the first clamping jaw 24 opens and clamps the tool handle 1001 of the old tool handle electrode 100;

[0065] Step 2, the tool changer 22 moves in a direction close to the second base 21 and approaches the initial position 151, the tool handle 1001 of the old tool handle electrode 100 is gradually stuck in the tool holder 14 during the movement of the tool changer 22, and then the first clamping jaw 24 opens and disengages from the tool handle 1001, and the tool changer 22 continues to move in a direction close to the second base 21 and resets;

[0066] Step 3, the control component determines the number 16 of the working position 152 where the new tool handle electrode 100 is located according to the model of the old tool handle electrode 100, then the tool disc 12 continues to rotate and stops at the corresponding working position, the tool changer 22 moves in a direction away from the second base 21 and approaches the working position 152, then the first clamp 24 and the second clamp 25 are opened respectively and clamp the tool handle 1001 and the electrode wire 1002 of the new tool handle electrode 100;

[0067] Step 4, the tool changer 22 continues to move in a direction away from the second base 21 and causes the new tool handle electrode 100 to separate from the tool holder 14. During the movement of the tool changer 22, the second clamping jaw 25 synchronously slides downward along the length direction of the electrode wire 1002;

[0068] Step 5, the tool changer 22 moves to the side of the machine tool spindle and installs the new tool holder electrode 100 into the spindle, then the first clamp 24 and the second clamp 25 open and disengage the tool holder 1001 and the electrode wire 1002 respectively, and the tool changer 22 moves in the direction close to the second base 21 and resets.

[0069] In this embodiment, the disassembly and replacement method also includes an initialization test implemented before step 1, and the initialization test includes: the first driving module 13 drives the cutter disc 12 to rotate, and the sensing module 17 passes through multiple workstations 152 in turn during the rotation stroke of the cutter disc 12 and detects the loading status of the tool holder 14 on each workstation 152. If there is an unloaded tool holder 14, the sensing module 17 sends an abnormal signal to the control component, and the control component marks the number 16 of the workstation 152 where the unloaded tool holder 14 is located. In this way, the control component can grasp the loading status on the tool holder 14 in real time, so as to accurately position the tool holder 14 when changing the tool, further improving the tool changing efficiency. After marking, the worker can replenish the tool holder electrode 100 of the unloaded tool holder 14 in time according to the marking situation, so as to avoid affecting the subsequent tool changing process due to the lack of the tool holder electrode 100.

[0070] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
