Specific embodiments

[0033] The following will further describe the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0034] First Embodiment

[0035] As Figures 1 - 7 shown, the electrode processing clamping tooling of the first embodiment of the present utility model includes:

[0036] A processing table 1, the top surface of the processing table 1 is a horizontal processing surface 11;

[0037] An installation component 2, the installation component 2 includes a fastener 21 and a mounting seat 22 that is detachably movable and fits on the processing surface 11, and the workpiece 4 is detachably arranged on the mounting seat 22 through the fastener 21;

[0038] A locking component 3, the locking component 3 is used to lock the mounting seat 22 on the processing table 1. The locking component 3 includes a locking member 31, a locking screw 32 and a locking nut 33. The axial direction of the locking screw 32 extends along the vertical direction. The locking member 31 is sleeved outside the locking screw 32, and the locking nut 33 is threadedly connected to the locking screw 32. In the locked state, the mounting seat 22 is clamped between the processing surface 11 and the locking member 31, and the locking component 3 is separated from the workpiece 4.

[0039] In this motor processing clamping tooling, the processing table 1 is used to connect with the machine tool. According to the model size of the workpiece 4, the corresponding mounting seat 22 is selected, and the workpiece 4 is fixed on the mounting seat 22 through the fastener 21. Then, the side of the mounting seat 22 facing away from the workpiece 4 is attached to the processing surface 11 of the processing table 1, and the position of the mounting seat 22 is adjusted, thereby adjusting the position of the workpiece 4. After the adjustment is completed, the locking component 3 is used to lock the mounting seat 22 on the processing surface 11, thereby fixing the position of the workpiece 4. Specifically, when locking, the locking nut 33 is rotated outside the locking screw 32, so that the locking nut 33 descends, causing the locking member 31 to descend, pressing on the mounting seat 22 and the locking component 3 is separated from the workpiece 4, avoiding the milling cutter contacting the locking component 3 during the milling process. By the locking member 31 descending and pressing on the mounting seat 22, the mounting seat 22 can be fixed on the processing surface 11, realizing the fixation of the positions of the mounting seat 22 and the workpiece 4.

[0040] In this embodiment, both the workpiece 4 and the mounting base 22 are disc-shaped, and the outer diameter of the mounting base 22 is larger than that of the workpiece 4. They are connected coaxially. After the workpiece 4 is connected to the mounting base 22 and the mounting base 22 is horizontally placed on the processing surface 11, the projection of the workpiece 4 on the horizontal plane is located inside the projection of the outer circumference of the mounting base 22 on the horizontal plane. In this way, it is convenient for the locking member 31 in the locking assembly 3 to apply pressure to the end of the mounting base 22 to fasten it to the processing table 1. The fastener 21 is a screw, and the screws are distributed in a circular array. After being screwed in from the side of the mounting base 22 adjacent to the processing surface 11, they are connected to the workpiece 4. In this way, a detachable fixed connection between the mounting base 22 and the workpiece 4 is achieved, so as to select a corresponding different mounting base 22 according to different workpiece 4 sizes and connect the workpiece 4 and the mounting base 22 through the fastener 21.

[0041] The processing table 1 is a rectangular plate-like structure, which is convenient for connecting with the machine tool.

[0042] After the fixing operation of the workpiece 4 and the mounting base 22 is completed, the machine tool can control the milling cutter to rotate and drive the milling cutter to move along the vertical direction, the length direction and the width direction of the processing table 1 by using the three-axis moving mechanism, so as to realize the milling of the workpiece 4 on the mounting base 22.

[0043] A further improvement is that at least two locking assemblies 3 are provided and distributed along the circumferential direction of the mounting base 22. By increasing the number of the locking assemblies 3, the number of locking points of the mounting base 22 is increased, and further the connection strength between the mounting base 22 and the processing table 1 in the locked state is strengthened, preventing the mounting base 22 and the workpiece 4 from shifting and jittering during the processing, which affects the processing accuracy. In this embodiment, two locking assemblies 3 are provided and distributed oppositely along the length direction parallel to the processing table 1.

[0044] A further improvement is that both the locking screw 32 and the locking member 31 slide on the processing table 1 along the direction parallel to the processing surface 11 to adjust the position of the locking screw 32 and the pressure application position of the locking member 31 on the mounting base 22 in the locked state. After adopting the above design, the positions of the locking screw 32 and the locking member 31 are adjustable, which is convenient for adjusting the positions of the locking screw 32 and the locking member 31 according to different workpieces 4 and mounting bases 22 to change the pressure application position on the mounting base 22, so as to ensure that after the mounting base 22 is locked to the processing table 1, the locking assembly 3 is prevented from contacting the workpiece 4.

[0045] A further improvement is that a plurality of slide grooves 12 distributed side by side are provided on the processing surface 11, and at least one end of the slide groove 12 extends to the circumferential outer edge of the processing table 1, and a locking slider 36 sliding in the slide groove 12 is fixed to the bottom end of the locking screw 32, and the plane size of the locking slider 36 is larger than the slot size of the slide groove 12; the locking piece 31 is a long locking strip, and the locking strip is provided with a locking slide 311 extending along its own length direction, and the locking slide 311 is for the locking screw 32 to pass through.

[0046] Specifically, the slide groove 12 extends in a length direction parallel to the processing table 1, and the slide groove 12 is a through groove with an inverted T-shaped cross section. The locking slider 36 is slidably matched with the lower part of the space in the slide groove 12 and is integrally connected with the bottom of the locking screw 32. In this way, the size of the locking slider 36 is larger than the slot space size of the slide groove 12. The locking slider 36 can only slide into or out of the slide groove 12 from both ends of the slide groove 12, and cannot be separated from the slide groove 12 in a direction perpendicular to the processing surface 11, so that it is convenient to select one of the slide grooves 12 to slide into the lock according to the size of the workpiece 4 and the mounting seat 22. The locking member 31 is designed with a long strip of structure, and the locking member 31 is a locking strip. When the mounting seat 22 is tightened, one end of the locking member 31 abuts against the side of the mounting seat 22 facing away from the processing surface 11. The locking member 31 is provided with a long strip of locking slide 311, which is convenient for adjusting the relative positions of the locking screw 32, the locking nut sleeve 33 and the locking member 31. In order to strengthen the locking strength, a locking washer 37 is also provided on the outside of the locking screw 32, and the locking washer 37 is clamped between the locking nut sleeve 33 and the locking member 31.

[0047] A further improvement is that a support block 34 is detachably provided at the other end of the locking strip, and in the locked state, the support block 34 is clamped between the locking strip and the processing table 1.

[0048] By setting the support block 34, in the locked state, one end of the locking strip is in contact with the top surface of the mounting seat 22 and is separated from the workpiece 4, while the other end of the locking strip is set on the support block 34. The support block 34 and the mounting seat 22 are used to support the two ends of the locking strip respectively, so that in the locked state, the length direction of the locking strip is parallel to the processing surface 11, thereby further ensuring the locking strength of the locking member 31 to lock the mounting seat 22 on the processing surface 11.

[0049] A further improvement is that the opposing surfaces of the support block 34 and the locking strip are serrated surfaces, which are inclined relative to the processing surface 11 , and the support block 34 is connected to a balancing slider 35 , which is slidably matched with the slide groove 12 .

[0050] By means of the mutual cooperation between the balance slider 35 and the chute 12, it is convenient to adjust the position of the support block 34, so that the serrated surface of the support block 34 and the serrated surface of the locking strip far from the mounting base 22 are closely attached, and both serrated surfaces are inclined to the processing surface 11, increasing the contact area between the support block 34 and the locking strip and strengthening the connection strength between the locking strip and the support block 34, thereby enhancing the locking effect on the mounting base 22.

[0051] Second Embodiment

[0052] As Figures 8 - 12 shown, the electrode processing clamping tooling of the second embodiment of the present utility model is based on the first embodiment, and the difference lies in that the processing table 1 is connected with an identification component for positioning and identifying the position of the mounting base 22.

[0053] Specifically, fixed frames 13 extending along the length direction of the processing table 1 are arranged on both sides of the bottom of the processing table 1. A slide bar 5 is arranged between the two fixed frames 13. The slide bar 5 passes through the inner sides of the two fixed frames 13 and sliding seats 51 are fixed at both ends. The surface of the sliding seat 51 adjacent to the slide bar 5 is attached to the fixed frame 13. A first limiting plate 54 is integrally connected to the slide bar 5 and is attached to the surface of the fixed frame 13 away from the sliding seat 51. In this way, it is convenient for the slide bar 5 and the sliding seat 51 to slide along the length direction of the processing table 1. First scale lines 14 are also arranged on both sides of the processing table 1. A pointer 52 is integrally connected to the surface of the sliding seat 51 away from the slide bar 5, and the pointer 52 points to the first scale line 14 to identify the position of the slide bar 5 relative to the length direction of the processing table 1.

[0054] A positioning component 6 is arranged on the sliding seat 51. The positioning component 6 includes a positioning screw 61 passing through the inner side of the sliding seat 51 and threadedly connected to the slide bar 5. Two second limiting plates 62 are arranged at one end of the positioning screw 61 at intervals along its axial direction. An adjusting block 63 is attached between the two second limiting plates 62. The adjusting block 63 is sleeved outside the positioning screw 61. Two guide rods 64 extending along the width direction of the processing table 1 are fixed to the surface of the adjusting block 63 adjacent to the fixed frame 13. Slide sleeves 53 corresponding to the two guide rods 64 one by one and in sliding fit are fixed on the sliding seat 51. A translation bar 65 is fixedly connected above the adjusting block 63 through a bolt 66. Two scale bars 67 arranged side by side along the length direction of the processing table 1 and extending along the width direction of the processing table 1 are fixedly connected to the translation bar 65. Second scale lines 671 are arranged on the scale bars 67 along their length directions. Rollers 68 with the axis lines extending in the vertical direction are arranged at the ends of the scale bars 67. Indicator bars 15 extending along the length direction of the processing table 1 are arranged on both sides of the processing surface 11.

[0055] After adopting the above structure, by rotating the positioning screw 61, while causing it to have an axial displacement, two second limiting plates 62 are driven to move, changing the position of the adjusting block 63, and further driving the translation bar 65 to move, changing the position of the roller 68. Since the wheel surfaces of the four rollers 68 are all in contact with the outer circumference of the mounting base 22, the mounting base 22 can be positioned. At this time, by observing the second scale line 671 on the scale bar 67 aligned with the indicating bar 15 on the processing table 1, the position of the mounting base 22 in the width direction relative to the processing surface 11 can be determined. Combining with the pointer 52 pointing to the first scale line 14 to identify the position of the sliding bar 5 in the length direction relative to the processing table 1, and further the specific position of the mounting base 22 on the processing surface 11 can be determined. In this way, the precise positioning of the mounting base 22 is achieved, which is beneficial to improving the machining accuracy of the machine tool for the workpiece 4.

[0056] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
