[0001] The present application relates to the technical field of machining machine tools, and in particular to an automated high-precision mold machining machine tool. Background Art

[0002] Automated mold processing machine tools are high-precision automated mechanical equipment specially used for manufacturing molds. They play a vital role in the mold manufacturing industry. According to the different needs of mold processing, automated mold processing machine tools can be divided into many types, such as CNC engraving and milling machines, CNC laser cutting machines, etc., which can realize the automated processing of molds.

[0003] In order to ensure the dimensional accuracy of the mold, the dimensional accuracy requirements for the processing machine tools in the stamping mold production process are generally relatively high.

[0004] In the related art, when the mold is processed by an automated processing machine, the processing accuracy is reduced in order to reduce the movement of the mold. Generally, multiple limit blocks are fixed on the processing machine to limit the movement of the mold during processing, thereby reducing the displacement of the mold on the processing machine. However, the molds to be processed usually have different shapes and sizes. It is difficult to limit the mold by simply limiting the mold with limit blocks. Summary of the invention In order to improve the stability of mold processing on an automated machine tool, the present application provides an automated high-precision mold processing machine tool.

[0006] By adopting the above technical solution, before processing the mold, the mold can be placed in the positioning box, and then the locking assembly and the fixing mechanism are adjusted to place the mold to be processed under the gate-shaped shape surrounded by multiple fixed blocks in the support rod, and the area surrounded by the fixed blocks is adjusted according to the shape of the mold. The position of the object to be protected in the positioning box is limited by multiple fixed blocks, and then two adjacent support rods are connected by a connecting assembly, thereby limiting the mold during the processing process through the support rod and the connecting assembly, reducing the displacement of the mold during the processing process and affecting the mold processing accuracy.

[0007] Optionally, a plurality of locking grooves are provided on the bottom surface of the positioning box, and the locking assembly includes two locking blocks and a plurality of first springs, the first springs are fixed between the locking blocks and the inner walls of the locking grooves, the fixed block is placed between the two locking blocks and under the action of the springs, the locking block abuts against the side walls of the fixed block.

[0008] By adopting the above technical solution, the two locking blocks can press the fixed block tightly through the abutment effect of the first spring, thereby restricting the fixed block in the locking groove and improving the stability of the entire support rod in the positioning box.

[0009] Optionally, within the same support rod, several fixed blocks located in the same column as the fixed blocks fixed to the positioning box are set as a first longitudinal fixed column; several fixed blocks arranged transversely are set as transverse fixed columns; fixed blocks located in the same column as the fixed blocks connected to the locking assembly are set as a second longitudinal fixed block column; the fixing mechanism includes a first limiting assembly for fixing the first longitudinal fixed column and a second limiting assembly for fixing the second longitudinal fixed column and the transverse fixed column.

Therefore, the length of each support rod can be adjusted according to the size of the mold to be processed, further limiting the position of the mold object in the positioning box and reducing the displacement of the mold in the positioning box.

[0011] Optionally, the first limiting assembly includes a plurality of first locking hooks, which are arranged along the height direction of the positioning box, and the spacing between two adjacent first locking hooks is the same as the length of the fixing block. A second spring is fixedly connected between the first locking hook and the inner wall of the positioning box, and two positioning blocks are fixedly connected to one end of the fixing block, and a positioning hole is provided on the positioning block, and a groove for placing the positioning block is provided at the other end of the fixing block, and the first locking hook at the same height as the uppermost fixed block in the first longitudinal fixing column is hung with the positioning hole of the positioning block on the uppermost fixed block in the first longitudinal fixing column.

[0013] The locking cam is configured to lock the locking cam of the locking cam and to lock the locking cam of the locking cam, wherein the locking cam has an end portion for locking the locking cam and a second end portion for locking the locking cam of the locking cam.

[0014] By adopting the above technical scheme, when fixing the transverse fixed column, one end of the fixing belt can be hooked on the first locking hook, and then the shell can be slid along the length direction of the transverse fixed column and the wire-releasing wheel can be used for wire-releasing at the same time. When the mounting shell slides to the upper end of the longitudinal fixed column, the limit block fixed on the mounting shell is inserted into the fixing hole on the uppermost fixing block in the second longitudinal fixed column. Thus, the relative rotation of the two fixing blocks here can be limited by the mounting shell. At the same time, the fixing belt will move with the mounting shell, and the first locking block and the second locking block fixed on the fixing belt will abut against each other, thereby limiting the rotation of the two adjacent fixing blocks in the transverse fixed column. Then, the wire-releasing wheel is fixed by the speed limiting member, so that the position of the fixing belt is fixed, thereby fixing the fixed blocks in the entire transverse fixed column.

[0015] Optionally, a rotating shaft is fixedly connected to the axis of the pay-off wheel, the rotating shaft is rotatably connected in the mounting shell, one end of the rotating shaft passes through the mounting shell and is placed outside the mounting shell, and the speed limiting part is configured as a locking nut, and the locking nut is threadedly connected to one end of the rotating shaft placed outside the mounting shell.

[0020] By adopting the above technical solution, when the lengths of the transverse fixed columns in two adjacent support rods are different, the third locking hook can be hooked into the fixing groove on the side wall of the sleeve, so that the connecting assembly is distributed more evenly between the two support rods and can adapt to changes in the length of the support rods.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Use multiple fixed blocks to limit the position of the object to be protected in the positioning box, and then connect two adjacent support rods through a connecting assembly, so that the mold during the processing is restricted by the support rods and the connecting assembly, reducing the displacement of the mold during the processing and affecting the mold processing accuracy; 2.

[0024] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0025] The embodiments of the present application are: Figure 1 and Figure 2 , an automated high-precision mold processing machine tool, reference Figure 1, including a machine tool body 1, which is a machine tool for high-precision automated processing of molds in the prior art. The machine tool body 1 includes a processing cutter head 11 installed on itself, and a positioning box 2 is fixedly connected to the machine tool body, and the processing cutter head 11 is placed above the positioning box 2. Three support rods 3 are arranged in the positioning box 2, and the three support rods 3 are placed on the same side wall of the positioning box 2, and the three support rods 3 are equidistantly arranged along the side wall of the positioning box 2 in the width direction.

[0026] The support rod 3 includes a plurality of fixed blocks 31 arranged linearly, and the fixed blocks 31 are arranged in a rectangular parallelepiped shape. Two adjacent fixed blocks 31 are connected in rotation, and the rotation point is located at the lower part of the two adjacent fixed blocks 31 close to each other. The fixed block 31 at one end of the support rod 3 close to the side wall in the width direction of the positioning box 2 is fixedly connected to the bottom end of the positioning box 2, and a plurality of fixed blocks 31 located in the same column as the fixed block 31 fixed to the positioning box 2 are arranged as a first longitudinal fixed column 32. A plurality of fixed blocks 31 arranged transversely are arranged as a transverse fixed column 33, and a locking assembly 4 for connecting the fixed block 31 at one end of the support rod 3 away from the side wall in the width direction of the positioning box 2 and the positioning box 2 is arranged between the two, and the fixed block 31 connected to the locking assembly 4 and located in the same column is arranged as a second longitudinal fixed column 34.

[0027] Reference Figure 2 and Figure 4 A plurality of locking grooves 21 are provided on the bottom surface of the positioning box 2. The locking grooves 21 are equidistantly arranged along the length direction of the positioning box 2, and the distance between two adjacent locking grooves 21 is the same as the length of the fixing block 31. The notch cover of the locking groove 21 and the cover plate 7 for shielding the locking groove 21 are provided. The locking assembly 4 includes two locking blocks 41 placed in the locking groove 21. The upper end surface of the locking block 41 is set as an inclined surface and the side of the two locking blocks 41 close to each other is inclined toward the bottom side of the locking groove 21. The side of the two locking blocks 41 away from each other is provided with a first spring 42. The first spring 42 is fixedly connected between the locking block 41 and the inner wall of the locking groove 21. Under the action of the first spring 42, the locking block 41 is pressed against the side wall of the fixing block 31.

[0028] Reference Figure 3 , Figure 5 and Figure 6 A fixing mechanism 5 for fixing the arrangement position of the fixing block 31 in the positioning box 2 is provided in the positioning box 2. The fixing mechanism 5 includes a first limiting component 51 for fixing the first longitudinal fixing column 32 and a second limiting component 52 for fixing the second longitudinal fixing column 34 and the transverse fixing column 33.

[0029] One end of the fixing block 31 is fixedly connected to two positioning blocks 312 , and positioning holes 3121 are formed on the positioning blocks 312 . The other end of the fixing block 31 is formed with a groove 311 for placing the positioning blocks 312 .

[0030] Reference Figure 3 The first limiting assembly 51 includes a plurality of first locking hooks 511, which are arranged along the height direction of the positioning box 2, and the first locking hooks 511 located at the support rods 3 in the middle of the three support rods 3 are arranged in two rows. The spacing between two first locking hooks 511 adjacent in the longitudinal direction is the same as the length of the fixing block 31. A second spring 512 is fixedly connected between the first locking hook 511 and the inner wall of the positioning box 2. Two first locking hooks 511 at the same height as the uppermost fixing block 31 in the first longitudinal fixing row 32 are respectively hooked with the positioning holes 3121 of the positioning block 312 on the uppermost fixing block 31 in the first longitudinal fixing row 32.

[0031] Therefore, under the restriction of the first locking hook 511 and the second spring 512 , the uppermost fixing block 31 in the first longitudinal fixing column 32 can be restricted from rotating away from the side wall of the positioning box 2 , thereby fixing the entire first longitudinal fixing column 32 .

[0032] Reference Figure 2 , Figure 3 and Figure 6 The second limiting assembly 52 includes two mounting shells 521. In the transverse fixed column 33, the mounting shells 521 are placed on both sides of the transverse fixed column 33. In the second longitudinal fixed column 34, the mounting shells 521 are placed on both sides of the second longitudinal fixed column 34. A pay-off wheel 522 is rotatably connected in the mounting shell 521. A fixing belt 523 is wound around the pay-off wheel 522. One end of the fixing belt 523 is wound around and fixedly connected to the arc-shaped side wall of the pay-off wheel 522. A plurality of first locking blocks 525 are fixedly connected to the fixing belt 523. The first locking blocks 525 are arranged along the length direction of the fixing belt 523. The spacing between two adjacent first locking blocks 525 is the same as the length of the fixed block 31. Second locking blocks 526 are fixedly connected to the side walls on both sides of the fixed block 31. The first locking blocks 525 abut against the second locking blocks 526. The mounting shell 521 is fixedly connected with a limit block 527, and the two limit blocks 527 are inserted into a positioning hole 3121 on the fixing block 31 in the transverse fixing column 33 near one end of the second longitudinal fixing column 34. The end of the fixing belt 523 in the transverse fixing column 33 away from the pay-off wheel 522 is hooked on the first locking hook 511. Figure 2 and Figure 3 A fixing hook 211 is fixedly connected in the locking groove 21 , and one end of the fixing belt 523 in the second longitudinal fixing column 34 away from the pay-off wheel 522 is hooked and hung on the fixing hook 211 .

[0033] Reference Figure 5 , a speed limiting member 524 for limiting the rotation of the pay-off wheel 522 is provided on the mounting shell 521. In this embodiment, the speed limiting member 524 is set as a nut. A rotating shaft 528 is passed through and fixedly connected to the axis of the pay-off wheel 522, and the rotating shaft 528 is rotatably connected in the mounting shell 521, so that the pay-off wheel 522 is rotatably connected in the mounting shell 521 through the rotating shaft 528. One end of the rotating shaft 528 passes through the mounting shell 521 and is placed outside the mounting shell 521, and a locking nut is threadedly connected to one end of the rotating shaft 528 placed outside the mounting shell 521, and a locking bolt abuts against the outer wall of the mounting shell 521.

[0034] When fixing the second longitudinal fixed column 34, one end of the fixing belt 523 on the second fixed column can be hung on the fixing hook 211, and then the mounting shell 521 is moved upward to make the pay-off wheel 522 in the mounting shell 521 pay-off. When the mounting shell 521 slides to the upper end of the second longitudinal fixed column 34, the limit block 527 fixed on the mounting shell 521 is inserted into the fixing hole on the fixing block 31 located on the side of the transverse fixed column 33 close to the second longitudinal fixed column 34. The locking nut is rotated to limit the rotation of the rotating shaft 528, thereby limiting the rotation of the pay-off wheel 522 in the mounting shell 521. At the same time, when the limit block 527 is inserted into the fixing hole, the fixing belt 523 will move together with the mounting shell 521, and make the first locking block 525 and the second locking block 526 abut against each other. Therefore, under the action of the first locking block 525 and the second locking block 526, it is difficult for the two adjacent fixing blocks 31 in the second longitudinal fixing column 34 to rotate relative to each other.

[0035] When fixing the transverse fixing row 33, one end of the fixing belt 523 can be hooked on the first locking hook 511, and then the same operation as that of fixing the second longitudinal fixing row 34 can be performed. At the same time, when the four limit blocks 527 are all inserted into the positioning holes 3121, the limit blocks 527 on the four mounting shells 521 can limit the relative rotation of the two fixing blocks 31, thereby fixing the connection between the transverse fixing row 33 and the second longitudinal fixing row 34.

[0036] Reference Figure 2 and Figure 7, multiple groups of connection components 6 for connecting the two are provided between two adjacent support rods 3. The connection component 6 is arranged between the transverse fixed column 33 and the second longitudinal fixed column 34. The connection component 6 includes a stud 61, one end of the stud 61 is hinged on the fixed block 31 by a ball hinge, and the other end of the stud 61 is threadedly connected with a sleeve 62, and the end of the sleeve 62 away from the stud 61 is provided with a third locking hook 63, and a third spring 64 is fixedly connected between the third locking hook 63 and the sleeve 62. The third locking hooks 63 located on different support rods 3 are hooked with each other. A fixing groove 621 is provided on the arc-shaped side wall of the sleeve 62, and the fixing groove 621 is arranged along the length direction of the sleeve 62, and the locking hook close to the second longitudinal fixed column 34 on the support rod 3 located in the middle of the three support rods 3 is hooked in the fixing groove 621.

[0037] The implementation principle of the embodiment of the present application is: adjust the number of rotatably connected fixing blocks 31 on each support rod 3 according to the size of the mold, so that the number of fixing blocks 31 in each support rod 3 is more compatible with the size of the mold.

[0038] Then, according to the height and shape of the mold to be processed, the height of the three support rods 3 is adjusted, that is, by adjusting the first limit assembly 51, the length of the first longitudinal fixed column 32 of the three support rods 3 is adjusted and the length of the first longitudinal fixed column 32 is fixed. Then, according to the length and shape of the mold to be processed, the length of the transverse fixed column 33 of the support rods 3 is adjusted and fixed by adjusting the second limit assembly 52, and then the second longitudinal fixed column 34 is fixed by adjusting the second limit assembly 52 on the second longitudinal fixed column 34, and the end of the support rod 3 away from the side wall of the positioning box 2 is fixed in the locking groove 21 through the locking assembly 4, so that the mold can be restricted on the positioning box 2 through the first longitudinal fixed column 32, the transverse fixed column 33 and the second longitudinal fixed column 34, so as to restrict the movement of the workpiece to be processed in any direction during the processing.

[0039] Then, it can be decided whether to hook the third locking hooks 63 in the multiple groups of connecting components 6 between the support rods 3 to each other according to the actual situation. When the connecting components 6 need to be set, the number of connecting components 6 needs to be flexibly set according to the processing position of the mold, and at the same time, it is necessary to prevent the connecting components 6 from affecting the stamping of the processing tool head 11 in the machine tool body 1. In this way, the three support rods 3 are connected to each other through the connecting components 6, and at the same time, the processed mold is restricted in the space formed by the multiple groups of connecting components 6 and the three support rods 3, further restricting the movement of the mold during the processing process.

[0040] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
