Description

Technical Field

[0001] The utility model belongs to the technical field of wire cutting fixtures, in particular to a wire cutting fixture for standard mold processing. Background Art

[0002] Standard mold processing wire cutting fixture, also known as fixture or tooling, is a device used to fix the processing object during the wire cutting process. Its main function is to ensure that the processed object maintains the correct processing position and placement during the processing, so as to facilitate accurate processing and improve production efficiency. By using the fixture, the workpiece can be quickly positioned and clamped, eliminating the time for auxiliary work such as marking and alignment.

[0003] The existing standard mold processing wire cutting fixture usually uses a pressure plate for clamping. When encountering a workpiece that requires oblique processing, it cannot meet the processing requirements of the front and rear oblique top holes, and the workpiece still needs to be disassembled and re-clamped, which not only affects work efficiency, but also requires re-correction of leveling and tool alignment during re-clamping, which increases the risk of human error during the calibration process, thereby affecting the quality of the mold. Utility Model Content

[0004] The utility model aims to provide a standard mold processing wire cutting fixture, which can adjust the horizontal and vertical angles of the clamped workpiece.

[0005] The standard mold processing wire cutting fixture comprises a base, on which two mounting seats are vertically fixed and symmetrically spaced in a front-to-back manner, a rotating seat capable of rotating left and right is arranged between the two mounting seats, an adjusting seat is vertically fixed on the top of the rotating seat, a supporting seat is rotatably connected to the left side of the adjusting seat, the supporting seat is rotatably connected to the adjusting seat in a front-to-back manner, and two clamping plates are connected to the left side surface of the supporting seat in an upper and lower interval, which are the first clamping plate and the second clamping plate from top to bottom;

[0006] The right end of the first clamping plate is connected to the support seat in an up-and-down sliding manner, the right end of the second clamping plate is fixed on the support seat, and the area between the first clamping plate and the second clamping plate is a clamping area for the workpiece;

[0007] The adjusting seat is provided with a first scale line for displaying the front and rear rotation angle of the supporting seat, and the mounting seat is provided with a second scale line for displaying the left and right rotation angle of the rotating seat.

[0008] Rotating the rotating seat left and right drives the adjustment seat to swing left and right, thereby realizing the angle adjustment of the clamped workpiece in the left and right direction; rotating the supporting seat forward and backward drives the workpiece to rotate forward and backward, thereby realizing the angle adjustment of the workpiece in the front and back directions; the first scale line and the second scale line can quantify the rotation angle, and adjust the angle of the workpiece in the left and right directions and the front and back directions as needed to make the workpiece cutting more accurate; through the rotation of the supporting seat and the rotating seat, the workpiece can be adjusted in the horizontal and vertical directions, so that the workpiece can be processed in different directions, which expands the processing capacity and application range of the fixture, reduces the number of clamping times of the workpiece, avoids the errors that may occur in the manual repeated positioning of the workpiece during repeated clamping, thereby improving the overall production efficiency.

[0009] Furthermore, a screw is vertically fixed on the upper surface of the second clamping plate, the lower end of the screw is fixed to the second clamping plate, and the upper end of the screw independently passes through the first clamping plate and is connected to a locking nut.

[0010] After the workpiece is placed in the clamping area, the first clamping plate is slid downward to clamp the workpiece and lock it with a locking nut, making it very convenient to clamp the workpiece.

[0011] Furthermore, a groove is formed at the right end of the first clamping plate, and a protrusion is vertically fixed on the support seat and is slidably matched with the groove.

[0012] The present design adopts a trapezoidal structure of grooves and protrusions, which may be T-shaped grooves and protrusions in actual use, or other structures that slide up and down.

[0013] Furthermore, the rotating seat is rotatably connected between the two mounting seats via a first bolt.

[0014] Specifically, two mounting seats are provided with through holes that communicate with each other front and back, and the screw rod of the first bolt is independently passed through the through hole and then a nut is installed, and the rotating seat is installed on the screw rod between the two mounting seats, and the rotating seat is fixed to the screw rod of the first bolt, and the first bolt rotates left and right in the through hole on the mounting seat, driving the rotating seat to rotate left and right.

[0015] Furthermore, the support seat is rotatably connected to the adjustment seat via a second bolt. Specifically, the screw rod of the second bolt independently passes through the adjustment seat and then extends into the support seat, and the portion extending into the support seat is fixed to the support seat.

[0016] The second bolt independently passes through the adjustment seat and can rotate forward and backward relative to the adjustment seat. The support seat fixed with the screw rod of the second bolt can rotate forward and backward along with the second bolt.

[0017] Furthermore, the adjustment seat is provided with a third bolt which is locked after the second bolt is rotated.

[0018] Specifically, a threaded hole that is in threaded fit with the screw rod of the third bolt is opened inward on the front side of the adjusting seat. After the screw rod of the third bolt is screwed into this threaded hole, it extends into the adjusting seat and abuts against the screw rod of the second bolt inward, thereby limiting the second bolt to prevent it from rotating, facilitating the positioning after the support seat rotates. In actual use, the number of the third bolts can be increased as needed.

[0019] Further, a fourth bolt for locking after the first bolt rotates is provided on the mounting seat.

[0020] Specifically, a threaded hole that is in threaded fit with the screw rod of the fourth bolt is opened inward on the right side of the mounting seat. After the screw rod of the fourth bolt is screwed into this threaded hole, it extends into the mounting seat and abuts against the screw rod of the first bolt inward, thereby limiting the first bolt to prevent it from rotating, facilitating the positioning after the rotating seat rotates. In actual use, the number of the fourth bolts can be increased as needed.

[0021] Further, a mounting groove is opened on the left side wall of the support seat, and the screw rod of the second bolt extends into the mounting groove.

[0022] The mounting groove facilitates the second bolt to pass through the support seat and extend into the mounting groove, and the support seat is fixed to the screw rod of the second bolt in the mounting groove. Specifically, the mounting groove is processed into a groove with a hexagonal cross-section, and a hexagonal nut that is in threaded fit with the second bolt is installed in the mounting groove. The second bolt passes through the support seat and extends into the mounting groove to be in threaded fit and fixed with the hexagonal nut, so that the support seat rotates together with the second bolt, facilitating the installation.

[0023] Further, through grooves that are open outward and communicate up and down are opened on the bases on the front and rear sides of the mounting seat.

[0024] The through grooves facilitate fixing the bases to the wire cutting machine tool through fasteners such as bolts.

[0026] Rotate the rotating seat left and right to drive the adjusting seat to swing left and right, realizing the angle adjustment of the clamped workpiece in the left and right directions; rotate the support seat forward and backward to drive the workpiece to rotate forward and backward, realizing the angle adjustment of the workpiece in the front and rear directions; the first scale line and the second scale line can quantify the rotated angle, and adjust the angle of the workpiece in the left and right directions and the front and rear directions according to needs, making the cutting of the workpiece more accurate; through the rotation of the support seat and the rotating seat, the workpiece can be adjusted in the horizontal and vertical angles, enabling the workpiece to be processed in different directions, expanding the processing capacity and application range of the fixture, and reducing the number of workpiece clamping times.

[0040] each;

[0041] The assembly method of the above materials is as follows:

[0042] Step 1: Manufacture

[0043] One support base 4;

[0044] As Figure 1 and Figure 7 shown, the main body of the support base 4 is a rectangular block. A convex block 19 is vertically connected to the left side surface of the support base 4. As Figure 4 shown, the cross-section of the convex block 19 is trapezoidal;

[0045] As Figure 1 shown, a mounting groove 3 with a hexagonal cross-section is opened at the vertical center of the left side wall of the support base 4 for placing a hexagonal nut that is threadedly engaged with the screw of the second bolt 9. A through hole penetrating to the right side of the support base 4 is opened on the support base 4 within the mounting groove 3; On the right side surface of the support base 4, as Figure 3 shown, a 0-bit line is marked at the vertical center.

[0046] Manufacture one first clamping plate 1;

[0047] As Figure 1 、 Figure 5 shown, the main body of the first clamping plate 1 is a rectangular block. A groove 18 is opened on the right side wall of the first clamping plate 1. As Figure 4 shown, the groove 18 is opened in a vertically sliding fit with the convex block 19 on the support base 4. A through hole for threading the screw 2 is opened on the first clamping plate 1 near the left side of the groove 18.

[0048] Manufacture one second clamping plate 5;

[0049] As Figure 1 、 Figure 5 and Figure 7 shown, the structure of the second clamping plate 5 is the same as that of the first clamping plate 1 and is processed by the same method.

[0050] Manufacture one rotating base 7;

[0051] As Figure 1 shown, the rotating base 7 is composed of a cylinder and a vertical rectangular block. The rectangular block is located in the left half of the top of the cylinder. The thickness of the rectangular block is the same as the radius of the cylinder. This rectangular block is the adjusting base 12. A through hole for threading the first bolt 8 is opened at the center of the cylinder;

[0052] As Figure 2 shown, a fillet is made at the top of the adjusting base 12. As Figure 3 shown, the diameter of the fillet at the top of the adjusting base 12 is equal to the length of the cylinder; As Figure 4As shown, scale marks are marked on the semi-circular surface of the top surface of the adjusting seat 12. This scale is the first scale line 13, and the specific precision of the scale digits depends on the usage requirements; a through hole for installing the second bolt 9 is opened at the center of the circular arc of the top corner of the adjusting seat 12.

[0053] Manufacture one base 6;

[0054] As Figure 3 shown, the base 6 is a rectangular block structure. Mounting seats 11 are installed on the base 6 at left and right intervals. The base 6 and the mounting seats 11 form a "U" shape;

[0055] As Figure 2 shown, chamfering is performed on the top surface of the mounting seat 11, and the radius of the chamfer is the same as the radius of the cylinder of the rotating seat 7;

[0056] As Figure 4 shown, stepped through grooves 10 are opened at the front and rear ends of the base 6 on the front and rear sides of the mounting seats 11; scale marks are marked on the circumferential surfaces of the two mounting seats 11 as the second scale line 16, and the specific precision of the scale digits depends on the usage requirements;

[0057] As Figure 2 shown, a through hole for installing the first bolt 8 is opened at the center of the circular arc of the top corner of the mounting seat 11.

[0058] Step 2: Assembly

[0059] As Figure 2 shown, place the base 6 horizontally; as Figure 1 shown, connect the rotating seat 7 to the base 6 in a left-right rotational connection through the first bolt 8. Specifically, the screw rod of the first bolt 8 independently passes through the through holes on the two mounting seats 11 and then a nut is sleeved. The rotating seat 7 is sleeved on the screw rod between the two mounting seats 11. The rotating seat 7 is fixed to the screw rod of the first bolt 8. The first bolt 8 rotates left and right in the through holes on the mounting seats 11, driving the rotating seat 7 to rotate left and right, and further driving the adjusting seat 12 to swing left and right;

[0060] A threaded hole that is threadedly engaged with the fourth bolt 17 is opened inward on the front side surface of the mounting seat 11. After the screw rod of the fourth bolt 17 is screwed into this threaded hole, it extends into the mounting seat 11 and abuts against the screw rod of the first bolt 8, thereby limiting the first bolt 8 to prevent it from rotating, facilitating the positioning after the rotating seat 7 rotates. In actual use, the number of the fourth bolts 17 can be increased according to needs;

[0061] The support base 4 is placed on the left side of the adjustment base 12 and then connected by the second bolt 9. The support base 4 can rotate back and forth relative to the adjustment base 12. Specifically, the screw rod of the second bolt 9 independently passes through the adjustment base 12 and then extends into the support base 4, and the part extending into the support base 4 is fixed to the support base 4. The installation groove 3 facilitates the second bolt 9 to pass through the support base 4 and extend into the installation groove 3, and in the installation groove 3, the support base 4 is fixed to the screw rod of the second bolt 9. Specifically, the installation groove 3 is processed into a groove with a hexagonal cross-section, and a hexagonal nut that is threadedly engaged with the second bolt 9 is installed in the installation groove 3. The second bolt 9 passes through the support base 4 and extends into the installation groove 3 and is threadedly engaged and fixed with the hexagonal nut, so that the support base 4 rotates together with the second bolt 9, which is convenient for installation;

[0062] A threaded hole that is threadedly engaged with the third bolt 14 is inwardly opened on the front side surface of the adjustment base 12. After the screw rod of the third bolt 14 is screwed into the threaded hole, it extends into the adjustment base 12 and abuts against the screw rod of the second bolt 9, thereby limiting the second bolt 9 to prevent the second bolt 9 from rotating, which is convenient for positioning the support base 4 after rotation. In actual use, the number of the third bolts 14 can be increased as needed;

[0063] The second clamping plate 5 is fixed to the bottom of the left side surface of the support base 4, and a screw rod 2 is vertically fixed to the top surface of the second clamping plate 5; as Figure 4 shown, the groove 18 on the right side of the first clamping plate 1 is sleeved on the convex block 19 on the left side of the support base 4, and the two are in a vertical sliding fit. The upper end of the screw rod 2 independently passes through the first clamping plate 1 and then is sleeved with a locking nut 15.

[0064] The usage instructions are as follows:

[0065] When in use, as Figure 5 and Figure 6 shown, first fix the base 6 to the wire cutting machine tool through the cooperation of the bolt and the through groove 10. First, move the first clamping plate 1 downward along the screw rod 2 through the cooperation of the screw rod 2 and the locking nut 15, so that the workpiece is clamped between the first clamping plate 1 and the second clamping plate 5, and then tighten the locking nut 15 to fix it;

[0066] Loosen the third bolt 14, and the support base 4 can rotate back and forth relative to the adjustment base 12 with the second bolt 9 as the axis line, so that the workpiece can be longitudinally angle-adjusted. After adjusting the angle, fix the second bolt 9 by tightening the third bolt 14, and the support base 4 no longer rotates;

[0067] Loosen the fourth bolt 17, and the rotating base 7 can rotate left and right relative to the mounting base 11 with the first bolt 8 as the axis line, so that the workpiece can be horizontally angle-adjusted. After adjusting the angle, fix the first bolt 8 by tightening the fourth bolt 17, and the rotating base 7 no longer rotates.

[0068] In the above scheme, the workpiece can be adjusted in the horizontal and vertical angles through the rotation of the support seat 4 and the rotating seat 7, so that the workpiece can be processed in different directions, expanding the processing capacity and application range of the machine tool. The adjustable angle simplifies the clamping process of the workpiece, avoids the time of repeated clamping, and reduces the errors that may occur when manually repeatedly positioning the workpiece, thereby improving the overall production efficiency.
