Description

Technical Field

[0001] The utility model relates to the field of mold parts processing, in particular to a copper male positioning fixture and an electric spark machine equipment. Background Art

[0002] In the field of mold manufacturing, spark discharge machining is a key technology, especially for those complex areas that are difficult to reach by machining centers, such as narrow and deep structures such as ribs and columns. These areas usually require extremely high machining accuracy, so higher technical requirements are placed on the discharge machining process. The traditional spark machining process relies on the precise installation of copper rods. Due to the complex three-dimensional shape characteristics of mold parts, it is often necessary to use multiple copper rods of different shapes and functions for step-by-step processing. Each copper rod needs to be recalibrated by the discharge technician. However, during the installation and adjustment process, if Figure 1 and Figure 2 As shown in the figure, the conventionally used fixture is only equipped with two screws for fixing and positioning the direction of the copper male. This double screw structure design makes it difficult to achieve synchronous force during the tightening operation, that is, the two screws cannot be tightened synchronously when tightening the screws, causing the copper male to tilt when the two screws are stressed one after another, which in turn causes the copper male to tilt in the Z-axis direction and cannot ensure the ideal vertical state. In addition, during the operation of manually tightening the screws, different tightening forces will also cause the copper male to be placed incorrectly, further causing quality problems in discharge machining. In the current workflow, technicians have to repeatedly perform calibration actions, and strive to keep the copper male or copper male horizontal in the X and Y axis directions and ensure that the Z axis is strictly vertical by repeatedly adjusting the two screws on the fixture and the four screws on the head of the spark machine. This cumbersome and time-consuming calibration method not only greatly increases the workload of discharge technicians and reduces work efficiency, but also because of its high reliance on manual operation skills, it is very easy to cause abnormal processing quality problems of mold parts caused by the failure of the copper male to be accurately placed. Therefore, how to overcome the processing defects caused by inaccurate copper male or copper male installation positioning in the prior art, simplify the calibration process, reduce the labor intensity of the operator, and effectively improve the working efficiency of the spark machine has become a technical problem that needs to be solved urgently.

[0042] The embodiment of the utility model solves the problem of wasting man-hours in repeated calibration and alignment of the existing copper male by providing a copper male positioning fixture and an electric spark machine device. The two sides of the copper male are clamped by a first Y-axis positioning plane and a second Y-axis positioning plane, and the Z-axis positioning plane at the top of the positioning member abuts against the head plane of the machine head, thereby realizing automatic alignment of the copper male in the X, Y and Z axis directions.

[0044] The specific solution is to set a first clamping block and a second clamping block on the fixture body, the first clamping block and the second clamping block can slide relative to the fixture body, the copper male is placed between the first clamping block and the second clamping block, and the first clamping block and the second clamping block are moved toward each other until the two parallel surfaces facing each other between the first clamping block and the second clamping block clamp the two sides of the copper male, thereby positioning the Y axis of the copper male; and a positioning piece with a flat top is vertically set on the fixture body, when the copper male positioning fixture is installed on the head of the electric spark machine, the flat top of the positioning piece abuts against the head positioning surface of the head, thereby positioning the Z axis of the copper male, ensuring that the copper male is vertical in the Z axis direction; in this way, the copper male is aligned by three-sided positioning (two parallel surfaces and a top plane), and the copper male is automatically aligned in the X, Y, and Z axis directions, avoiding processing errors caused by manual calibration, ensuring processing quality, saving the working hours required for calibration and alignment, reducing employee workload and labor intensity, and improving employee work efficiency and the effective processing efficiency of the spark machine.

[0045] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] Reference Figure 3-Figure 14 The embodiment of the utility model provides a copper male positioning fixture 100, comprising: a fixture body 10, a clamping block assembly 20 and a positioning member 30, the fixture body 10, comprising a copper male positioning surface 11 and a head mounting surface 12 opposite to each other; the clamping block assembly 20, comprising a first clamping block 21 and a second clamping block 22, the first clamping block 21 and the second clamping block 22 are movably arranged on the copper male positioning surface 11, the first clamping block 21 is provided with a first Y-axis positioning plane 211 on one side facing the second clamping block 22, and the second clamping block 2 A second Y-axis positioning plane 221 is provided on one side facing the first clamping block 21, the first Y-axis positioning plane 211 is parallel to the second Y-axis positioning plane 221, and when the first clamping block 21 and the second clamping block 22 are close to each other, the first Y-axis positioning plane 211 and the second Y-axis positioning plane 221 clamp the two sides of the copper male 300; a positioning member 30 is vertically provided on the head mounting surface 12, and a Z-axis positioning plane 311 is provided on the top of the positioning member 30 away from the head mounting surface 12.

[0047] Reference Figure 3 and Figure 4Specifically, the copper male 300 is the electrode material used when the electrical discharge machining (EDM) process is adopted in mold production. The copper male 300 is usually used to process the mold cavity or other complex geometric features. The fixture body 10 is a rectangular body structure as a whole. The copper male positioning surface 11 and the head mounting surface 12 are respectively located on the two opposite sides of the fixture body 10. The copper male positioning surface 11 is used to position the copper male 300, and the head mounting surface 12 is used to install the head 200 of the EDM machine equipment. The copper male positioning surface 11 is provided with a first clamping block 21 and a second clamping block 22 arranged opposite to each other. The first clamping block 21 and the second clamping block 22 can move on the copper male positioning surface 11. It should be noted that there are many structures that enable the first clamping block 21 and the second clamping block 22 to move on the copper male positioning surface 11, which are not limited here. A first Y-axis positioning plane 211 is provided on the inner side of the first clamping block 21, and a second Y-axis positioning plane 221 is provided on the inner side of the second clamping block 22. The first Y-axis positioning plane 211 is parallel to the second Y-axis positioning plane 221. When installing the copper male 300, the copper male 300 is placed between the first clamping block 21 and the second clamping block 22, so that the first clamping block 21 and the second clamping block 22 move toward each other, and the first Y-axis positioning plane 211 and the second Y-axis positioning plane 221 clamp the two sides of the copper male 300. Since the first Y-axis positioning plane 211 and the second Y-axis positioning plane 221 are parallel to each other, the Y-axis of the copper male 300 can be straightened to achieve positioning of the Y-axis of the copper male 300. The positioning member 30 is vertically arranged on the head mounting surface 12, and the top of the positioning member 30 is higher than the head mounting surface 12. The top of the positioning member 30 is provided with a Z-axis positioning plane 311. When the copper male positioning fixture 100 is installed on the head 200 of the EDM machine equipment, the Z-axis positioning plane 311 abuts against the head plane 201 of the head 200. Because both are planes and the positioning member 30 is vertical, the Z-axis of the copper male 300 can be aligned, and the Z-axis direction is vertical, thereby positioning the Z-axis of the copper male 300. The top surface (Z-axis) and the inner and outer directions (Y-axis) of the copper male 300 are positioned by positioning on three surfaces (the first Y-axis positioning plane 211, the second Y-axis positioning plane 221, and the Z-axis positioning plane 311), so that the X-axis is positioned by the Y and Z axes, and the X, Y, and Z-axis directions of the copper male 300 are automatically aligned.

[0048] Through the embodiments of the utility model, the discharge machining process is simplified, the work efficiency of the discharge technicians and the productivity of the electric spark machine equipment are improved, the machining quality is guaranteed, the machining cycle is shortened, and the effects of increasing production and efficiency and saving energy and reducing consumption are achieved.

[0049] Reference Figure 5 and Figure 6In one embodiment, a linear slide groove 111 is provided on the copper male positioning surface 11 and passes through both sides of the clamp body 10. The first clamp block 21 and the second clamp block 22 are respectively provided with a first hanging platform 212 and a second hanging platform 222 on the side facing the copper male positioning surface 11. The first hanging platform 212 and the second hanging platform 222 are slidably embedded in the linear slide groove 111. Specifically, in order to realize the sliding of the first clamp block 21 and the second clamp block 22 on the copper male positioning surface 11, a linear slide groove 111 is provided on the copper male positioning surface 11. The linear slide groove 111 extends linearly along the clamp body 10 and passes through both sides of the clamp body 10, so that the linear slide groove 111 forms a through groove structure. The cross section of the linear slide groove 111 is a T-shaped groove structure. The middle protrusion of the first clamp block 21 forms a T-shaped first hanging platform 212. Similarly, the middle protrusion of the second clamp block 22 forms a T-shaped second hanging platform 222. The first bracket 212 of the first clamp 21 is embedded in the T-shaped linear slide 111 from one side of the clamp body 10, and the second bracket 222 of the second clamp 22 is embedded in the T-shaped linear slide 111 from the other side of the clamp body 10. Of course, it can be understood that the first bracket 212 and the second bracket 222 can be embedded in the T-shaped execution slide on the same side. The first clamp 21 slides along the T-shaped linear slide 111 through the T-shaped first bracket 212, so that the first clamp 21 slides on the copper male positioning surface 11. Similarly, the second clamp 22 slides along the T-shaped linear slide 111 through the T-shaped second bracket 222, so that the second clamp 22 slides on the copper male positioning surface 11. Moreover, through the cooperation of the T-shaped first bracket 212, the second bracket 222 and the T-shaped linear slide 111, the first clamp 21 and the second clamp 22 can be hung on the clamp body 10 without falling, with a simple structure and easy installation. In addition, the copper male 300 has different types, for example, a straight copper male 300 and a cross copper male 300, and the sizes of the straight copper male 300 and the cross copper male 300 are different. Therefore, when replacing different types of copper males 300, such as Figure 7 and Figure 8 As shown, the distance between the first clamping block 21 and the second clamping block 22 can be adjusted by sliding the first clamping block 21 and the second clamping block 22 to adapt to different types of copper males 300, thereby improving the versatility of the clamp.

[0050] Continue to refer to Figure 5 and Figure 6In this embodiment, the clamp body 10 is provided with a first positioning groove 112 and a second positioning groove 113 that pass through the copper male positioning surface 11 and the head mounting surface 12. The first positioning groove 112 and the second positioning groove 113 are parallel to the linear slide 111 and are located at the upper and lower sides thereof. The clamp block assembly 20 also includes a plurality of first fasteners 23. The plurality of first fasteners 23 pass through the first positioning groove 112 and the second positioning groove 113 from the head mounting surface 12 and are fastened to the first clamp block 21 and the second clamp block 22 on the copper male positioning surface 11 respectively. Specifically, in order to fasten the first clamp block 21 and the second clamp block 22 after clamping the copper male 300, the clamp body 10 is provided with a first positioning groove 112 and a second positioning groove 113. The first positioning groove 112 and the second positioning groove 113 are also linear grooves. The first positioning groove 112 and the second positioning groove 113 are located at the upper and lower sides of the linear slide 111 respectively, and the three are parallel to each other. The first positioning groove 112 and the second positioning groove 113 are through grooves, which penetrate the copper male positioning surface 11 and the head mounting surface 12. The inner walls of the first positioning groove 112 and the second positioning groove 113 are formed with mounting steps in the shape of inner flanges (not shown in the figure). The first clamping block 21 and the second clamping block 22 are in the shape of long strips. The upper and lower ends of the first clamping block 21 and the second clamping block 22 in the length direction respectively have intersecting parts with the first positioning groove 112 and the second positioning groove 113. Screw holes are respectively provided at the upper and lower ends of the first clamping block 21 and the second clamping block 22. The first fastener 23 is a hexagon socket screw. The head diameter of the hexagon socket screw is slightly smaller than the diameter of the first positioning groove 112 and the second positioning groove 113. The diameter of the stem of the hexagon socket screw is slightly smaller than the inner diameter of the mounting step. When installing the hexagon socket screw, it is inserted into the first positioning groove 112 and the second positioning groove 113 from one side of the machine head mounting surface 12. The rod of the hexagon socket screw passes through the mounting step and is threadedly matched with the screw holes on the first clamp block 21 and the second clamp block 22. The head of the hexagon socket screw abuts against the mounting step, thereby achieving the fastening of the first clamp block 21 and the second clamp block 22, and then clamping the copper male 300.

[0051] Continue to refer to Figure 5 and Figure 6In this embodiment, the clamping block assembly 20 further includes a plurality of second fasteners 24. A secondary fastening surface 213 is provided on the side of the first clamping block 21 facing away from the first Y-axis positioning plane 211. A plurality of secondary positioning holes 214 are provided on the secondary fastening surface 213 and penetrate the first Y-axis positioning plane 211. The second fasteners 24 are used to secondarily fasten the copper male 300 through the secondary positioning holes 214. Specifically, in order to further fasten the copper male 300, a second fastener 24 is further provided to fasten the copper male 300 from the side of the copper male 300. The second fastener 24 is a positioning screw plug. A secondary fastening surface 213 is provided on the outer side surface of the first clamping block 21. The secondary fastening surface 213 is opposite to the first Y-axis positioning plane 211. A plurality of secondary positioning holes 214 are provided on the secondary fastening surface 213. The secondary positioning holes 214 penetrate the secondary fastening surface 213 and the first Y-axis positioning plane 211. After clamping the copper male 300, the positioning bolt is screwed in from the secondary fastening surface 213, that is, the positioning screw plug is screwed inward, the positioning screw plug will move toward the copper male 300, and the positioning screw plug will pass through the first Y-axis positioning plane 211 to contact the copper male 300 and fix the copper male 300. In other words, when the positioning screw plug is tightened inward, it presses against the copper male 300 to achieve secondary fastening.

[0052] In one embodiment, the head mounting surface 12 is provided with a plurality of insertion holes 121 around the center of the fixture body 10, and the positioning member 30 includes a plurality of limiting posts 31, the bottom ends of the limiting posts 31 are vertically inserted into the insertion holes 121, and the top ends of the limiting posts 31 are higher than the head mounting surface 12. Specifically, the positioning member 30 includes four limiting posts 31, and the head mounting surface 12 is provided with four insertion holes 121, and the four insertion holes 121 are distributed in four diagonal shapes of a rectangle. The limiting column 31 is a cylinder, the insertion hole 121 is a round hole, the limiting column 31 has a certain height, the limiting column 31 is vertically inserted into the insertion hole 121, the bottom end of the limiting column 31 is located in the insertion hole 121, the column body of the limiting column 31 extends out of the head mounting surface 12, and the top end of the limiting column 31 is higher than the head mounting surface 12, so that the Z-axis positioning plane 311 at the top end of the limiting column 31 is against the head 200 positioning plane of the head 200. In this way, the reliability of the Z-axis positioning of the copper male 300 is improved by four vertical limiting columns 31 distributed around the center of the fixture body 10 and against the head plane 201 respectively.

[0053] Continue to refer to Figure 5In this embodiment, the positioning member 30 further includes a plurality of limiting nuts 32, which are sleeved on the outer side of the column of the limiting column 31 that is higher than the head mounting surface 12. Specifically, since only the top end of the limiting column 31 is subjected to force against the head 200, the limiting column 31 is prone to tilting when the force is unbalanced. Therefore, in order to ensure the verticality of the limiting column 31, the limiting nuts 32 are sleeved on the outer side of the column of the limiting column 31 that is higher than the head mounting surface 12, so as to increase the force area of ​​the limiting column 31, and the limiting nuts 32 support the limiting column 31, thereby preventing the limiting column 31 from tilting, improving the verticality of the limiting column 31, and improving the reliability of Z-axis positioning.

[0054] Continue to refer to Figure 5 In one embodiment, the head mounting surface 12 is further provided with at least two rotation limiting holes 122, and the rotation limiting holes 122 are used for inserting the rotation limiting positioning posts 202 of the head 200. Specifically, the rotation limiting holes 122 are circular holes, which are distributed diagonally on the head mounting surface 12. When the copper male positioning fixture 100 is installed on the head 200 of the EDM machine, the two rotation limiting positioning posts 202 of the head 200 are inserted into the two rotation limiting holes 122, thereby preventing the fixture body 10 from rotating, thereby positioning the X and Y axes of the fixture body 10.

[0055] Reference Figure 9-Figure 14 The embodiment of the utility model further provides an EDM machine device, including a machine head 200 and a copper male positioning fixture 100, wherein the copper male positioning fixture 100 is the copper male positioning fixture 100 of the above embodiment, and the copper male positioning fixture 100 further includes a mounting assembly 40 mounted on the machine head mounting surface 12, and the copper male positioning fixture 100 is mounted on the machine head 200 through the mounting assembly 40. Specifically, the copper male positioning fixture 100 has been described in detail in the above embodiment, and for the sake of brevity of the specification, it will not be repeated here.

[0058] The embodiment of the utility model also provides a method for installing a copper male positioning fixture 100, which is applied to the above-mentioned electric spark machine equipment. Fig.15 1 is a schematic flow chart of the steps of the installation method of the copper male positioning fixture 100 according to an embodiment of the utility model, and the method includes steps: S1-S3.

[0059] S1, clamping two sides of the copper male 300 through the first Y-axis positioning plane 211 of the first clamping block 21 and the second Y-axis positioning plane 221 of the second clamping block 22 and fastening the first clamping block 21 and the second clamping block 22;

[0060] S2, the copper male positioning fixture 100 is installed and fixed to the machine head 200 through the installation assembly 40, and the Z-axis positioning plane 311 at the top of the positioning member 30 is pressed against the machine head plane 201 of the machine head 200 facing the machine head installation surface 12;

[0061] S3, making the copper male 300 directly touch the mold part 400 to be processed, and resetting the parameters of the electric spark machine equipment to zero to set the processing origin.

[0062] In this embodiment, first, the hexagon socket screws on the first clamp block 21 and the second clamp block 22 are loosened, and the first clamp block 21 and the second clamp block 22 are moved to a suitable position larger than the copper male 300; then the copper male 300 is placed between the first clamp block 21 and the second clamp block 22, so that the first clamp block 21 and the second clamp block 22 move toward each other to clamp the copper male 300, and the hexagon socket screws are tightened to fix the copper male 300, and then the positioning screw plug on the first clamp block 21 is tightened inward to tighten the copper male 300 for the second time; then the installation component 40 of the copper male positioning fixture 100 equipped with the copper male 300 is installed in the spark machine head 200, and the limit column The Z-axis positioning plane 311 at the top of 31 just supports the head plane 201 of the machine head 200, thereby automatically aligning the X, Y, and Z axes of the copper male 300; finally, the plane of the copper male 300 touches the mold part 400 to be processed. When the copper male 300 loaded on the EDM machine touches the mold part 400 to be processed, the EDM machine will emit an alarm sound, and the technician will operate the EDM machine to reset its parameters to zero. The EDM machine will obtain the coordinate numbers X, Y, and Z axes where the copper male 300 and the mold part 400 to be processed are in contact, thereby setting the EDM machine movement processing origin, setting the coordinate numbers and current to start discharge machining.

[0063] Through this embodiment, the copper male positioning fixture 100 of this embodiment is used to position the copper male 300. When the electric spark machine is used for discharge processing, it is no longer necessary to calibrate and align the X, Y, and Z axis directions of the copper male 300. The discharge processing can be directly performed on the origin of the mold part 400. There is no need to calibrate and align the X, Y, and Z axes for each copper male 300, which reduces the workload of the discharge technician and releases the effective working time of the spark machine, thereby improving the work efficiency of employees and equipment.
