DETAILED DESCRIPTION

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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.

[0040] See also Figure 1 , Figure 2 and Figure 3, the wire cutting positioning device provided by the utility model is now described. The wire cutting positioning device includes a base 1, a first adjustment seat 2, a second adjustment seat 3, a clamping seat 4 and a locking mechanism. Among them, the first adjustment seat 2 is rotatably set on the base 1. The second adjustment seat 3 is rotatably set on the first adjustment seat 2. The clamping seat 4 is fixedly set on the second adjustment seat 3 for clamping the workpiece. The locking mechanism is used to adjust and fix the positions of the first adjustment seat 2 and the second adjustment seat 3. The rotation axes of the first adjustment seat 2 and the second adjustment seat 3 are perpendicular to each other.

[0041] Specifically, the base 1 is installed on the wire cutting machine, the rotation axis of the first adjustment seat 2 is vertically arranged, and the rotation axis of the second adjustment seat 3 is horizontally arranged, so that the first adjustment seat 2 can adjust the angle in the horizontal direction, and the second adjustment seat 3 can adjust the pitch angle in the vertical direction. The bottom end of the second adjustment seat 3 is arranged in an arc shape, and an arc groove matching the shape of the bottom end of the second adjustment seat 3 is opened on the first adjustment seat 2, so that the bottom end of the second adjustment seat 3 fits with the inner wall of the arc groove of the first adjustment seat 2, and when the second adjustment seat 3 rotates, the bottom end of the second adjustment seat 3 slides in the arc groove, so that the second adjustment seat 3 is more stable when rotating.

[0042] After the clamping seat 4 clamps the workpiece, the first adjustment seat 2 and the second adjustment seat 3 are adaptively adjusted according to the inclined surface that needs to be processed on the workpiece by using the locking mechanism, so that the cutting angle of the workpiece can be matched with the cutting line of the wire cutting machine, thereby realizing adaptive adjustment of workpieces with different processed inclined surfaces.

[0043] In some embodiments, see Figure 1 and Figure 2 The locking mechanism includes a first locking assembly, and the first locking assembly includes a worm wheel 51 and a worm 52. The worm wheel 51 is rotatably arranged on the base 1. The worm 52 is rotatably arranged on the base 1. The worm wheel 51 is fixedly connected to the first adjustment seat 2, and the worm wheel 51 and the worm 52 are meshed.

[0044] Specifically, among the worm wheel 51 and the worm 52, the worm 52 is the active part and the worm wheel 51 is the driven part. Due to the self-locking property between the worm wheel 51 and the worm 52, when the worm 52 drives the worm wheel 51 to rotate to a certain angle, the worm 52 no longer rotates, and the position of the worm wheel 51 can be locked, thereby achieving the fixation of the position of the first adjustment seat 2 and ensuring the stability of the first adjustment seat 2 during the online cutting process. In addition, one end of the worm 52 extends outward through the base 1 and is fixedly connected to the first handle, so that the staff can easily rotate the worm 52 through the first handle, thereby achieving the adjustment of the angle of the first adjustment seat 2.

[0045] When adjusting, the worm 52 is rotated by the first handle, the worm 52 drives the worm wheel 51 to rotate, and the worm wheel 51 drives the first adjustment seat 2 to rotate, thereby achieving the adjustment of the position of the first adjustment seat 2.

[0046] In some embodiments, see Figure 1 and Figure 3 The locking mechanism further includes a second locking assembly, which includes a rack 61, a gear 62 and an adjusting screw 63. The rack 61 is slidably arranged on the first adjusting seat 2. The gear 62 is fixedly arranged on the second adjusting seat 3. The adjusting screw 63 is rotatably arranged on the first adjusting seat 2. The rack 61 and the gear 62 are meshed, and the rack 61 and the adjusting screw 63 are threadedly connected.

[0047] Specifically, a notch for accommodating the gear 62 and the rack 61 is provided in the middle of the second adjustment seat 3. The gear 62 is a half gear, and the top of the gear 62 is fixed to the second adjustment seat 3. The rotation axis of the gear 62 and the second adjustment seat 3 coincides, and the length direction of the rack 61 is the same as the axial direction of the adjusting screw 63. By rotating the adjusting screw 63, the rack 61 can be translated on the first adjustment seat 2. During the movement, the rack 61 drives the gear 62 to rotate, and the gear 62 drives the second adjustment seat 3 to rotate, thereby adjusting the pitch angle of the second adjustment seat 3. At the same time, due to the threaded connection between the rack 61 and the adjusting screw 63, the gear 62 cannot drive the rack 61 to move, thereby locking the position of the second adjustment seat 3 and ensuring the stability of the wire cutting process.

[0048] In addition, one end of the adjusting screw 63 passes through the first adjusting seat 2 and extends outward and is fixedly connected to the second handle, so that the staff can easily drive the adjusting screw 63 to rotate through the second handle, thereby adjusting the angle of the second adjusting seat 3.

[0049] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The clamping seat 4 includes a seat body 41, a bidirectional screw 42, two movable seats 43 and two clamping seats 44. The seat body 41 is fixedly arranged on the second adjustment seat 3. The bidirectional screw 42 is rotatably arranged on the seat body 41. The two movable seats 43 are respectively threadedly connected to the two ends of the bidirectional screw 42 and are slidably connected to the seat body 41. The two clamping seats 44 correspond to the two movable seats 43 one by one and are respectively plugged into the two movable seats 43.

[0050] Specifically, one end of the bidirectional screw 42 passes through the seat body 41, extends outward and is fixedly connected to a third handle, so that the staff can conveniently drive the bidirectional screw 42 to rotate through the third handle, thereby adjusting the positions of the two movable seats 43, so that the two movable seats 43 move toward or away from each other, thereby driving the two clamping seats 44 to clamp and release the workpiece.

[0051] By plugging the clamping seat 44 into the movable seat 43, different workpieces can be clamped by replacing different clamping seats 44. When clamping some special-shaped workpieces, the clamping seat 44 that matches the shape of the workpiece can be replaced, thereby improving the fit between the clamping seat 44 and the workpiece, making the workpiece more stable when clamped.

[0052] In some embodiments, see Figure 4 A slot 431 is provided on the movable seat 43 , and an insert block 441 is fixedly provided on the clamp seat 44 , and the insert block 441 is inserted into the slot 431 .

[0053] Specifically, when connecting the clamp seat 44 and the movable seat 43 , align the plug block 441 and the slot 431 , and then insert the plug block 441 into the slot 431 to achieve the connection between the two, making it more convenient and quick for the staff to install and disassemble the clamp seat 44 .

[0054] Based on the above embodiments, further, the slot 431 is a dovetail slot, and the insert block 441 is a trapezoidal block.

[0055] By setting the slot 431 as a dovetail slot and the insert block 441 as a trapezoidal block, the placement of the clamp seat 44 is limited in shape, so that after the two clamp seats 44 are installed, the clamping surfaces of the clamp seats 44 are arranged relative to each other, which fundamentally avoids the situation where the staff makes installation errors and plays a fool-proof role. At the same time, the setting of the dovetail slot and the dovetail block makes the clamp seat 44 more stable after being inserted into the movable seat 43, and will not twist, thereby improving the stability when clamping the workpiece.

[0056] Optionally, the slot 431 may be a triangular slot, and the insert block 441 may be a triangular block.

[0057] In some embodiments, see Figure 4 A first magnet 442 is embedded in the clamp seat 44 , and a second magnet 432 is embedded in the movable seat 43 . When the clamp seat 44 is plugged into the movable seat 43 , the first magnet 442 and the second magnet 432 are attracted to each other.

[0058] Specifically, the outer surface of the first magnet 442 is flush with the outer surface of the clamping seat 44, and the outer surface of the second magnet 432 is flush with the outer surface of the movable seat 43. The opposing surfaces of the first magnet 442 and the second magnet 432 are opposite magnetic poles, so that when the clamping seat 44 is plugged into the movable seat 43, the first magnet 442 and the second magnet 432 will not only fit together, but also be attracted to each other due to magnetism, thereby improving the stability and convenience of the connection between the clamping seat 44 and the movable seat 43.

[0059] In some embodiments, see Figure 1 and Figure 4 A fixing bolt 433 is threadedly connected to the movable seat 43 . When the clamp seat 44 is inserted into the movable seat 43 , the fixing bolt 433 penetrates the clamp seat 44 and is threadedly connected to the movable seat 43 .

[0060] Specifically, a threaded hole matching the fixing bolt 433 is provided on the movable seat 43, and a through hole for the fixing bolt 433 to pass through is provided on the clamp seat 44, so that when the clamp seat 44 is plugged into the movable seat 43, the threaded hole and the through hole can be aligned, which facilitates the staff to connect the fixing bolt 433. The clamp seat 44 and the movable seat 43 are fixed together by the fixing bolt 433, which ensures the firmness of the clamp seat 44 when in use and improves the stability during wire cutting processing.

[0061] In some embodiments, see Figure 1 and Figure 2 The clamp seat 44 is provided with anti-skid patterns 443. Specifically, the anti-skid patterns 443 are provided on the opposite surfaces of the two clamp seats 44, and the anti-skid patterns 443 can effectively increase the friction coefficient of the clamp seat 44, so that the clamp seat 44 is more secure when clamping the workpiece, and it is not easy for the workpiece and the clamp seat 44 to slip.

[0062] In some embodiments, see Figure 1 , a scale is provided on the base 1. The scale on the base 1 can facilitate the staff to adjust the position of the first adjustment seat 2 according to the scale, making it more intuitive and convenient for the staff to observe and adjust the position of the first adjustment seat 2, reducing the difficulty of adjustment.

[0063] In summary, compared with the prior art, the wire cutting positioning device provided by the utility model can adjust the angles of the first adjustment seat 2 and the second adjustment seat 3 respectively through the locking mechanism after the workpiece is clamped and fixed by the clamping seat 4. Among them, the first adjustment seat 2 realizes the adjustment of the angle on the horizontal plane of the workpiece, and the second adjustment seat 3 realizes the adjustment of the angle on the vertical plane of the workpiece, thereby being able to drive the workpiece to achieve the adjustment of various different angles, and being able to adapt to the processing of workpieces with different inclined surfaces, so that the adaptability range is wider.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
