Description

Technical Field

[0001] This application relates to the field of forging auxiliary device technology, and in particular to a long tool rack fixture for forward and reverse tool holders of a CNC lathe. Background Technology

[0002] With the rapid development of the national equipment manufacturing and energy industries, deep hole machining is indispensable in the large-scale machinery manufacturing industry. As the volume and weight of the workpieces being machined continue to increase, most deep hole equipment is currently insufficient to meet the machining needs of deep holes in large parts, especially for large blind holes.

[0003] The main difficulty in deep hole machining lies in the depth and size of the hole. For through holes, the difficulty of machining the hole length can be reduced by connecting the two sides, but blind hole machining is more difficult.

[0004] Deep hole machining tools typically use boring bars to enlarge through holes, but this is insufficient for machining large-diameter blind holes. While boring machines can be used, most have excessive deflection of their long boring bars, resulting in insufficient rigidity and failing to meet machining requirements. In this case, using long tool bars to machine large blind holes is a good option. However, long tool bars require a support base for installation. Only a few horizontal lathes have a base for mounting long tool bars, but these machines generally have limited load-bearing capacity, making it difficult to machine large parts. Most newer, large CNC horizontal lathes, while having high load-bearing capacity, only have forward and reverse tool posts and lack a support platform such as a base for mounting long tool bars. Utility Model Content

[0005] The purpose of this application is to solve the problem that long tool racks cannot be installed on existing CNC lathes. Therefore, this application provides a long tool rack fixture for the forward and reverse tool posts of a CNC lathe. The fixture's base plate is detachably connected to the forward and reverse tool posts, allowing the CNC lathe to clamp long tool racks for machining large blind holes in workpieces without damaging the lathe. Furthermore, the fixture's load-bearing plate, stiffening plate assembly, and the cooperation of the first and second baffles ensure the rigidity and stability requirements for machining long tool racks, thus guaranteeing machining reliability.

[0006] This application provides a long tool rack fixture for forward and reverse tool holders of a CNC horizontal lathe, including a base plate and a load-bearing plate vertically connected to the base plate;

[0007] The base plate is used to detachably connect to the housing of the CNC lathe's forward and reverse tool post, and allows the load-bearing plate to be located between the two tool holders of the CNC lathe's forward and reverse tool post.

[0008] The width of the load-bearing plate is adapted to the distance between the two tool holders on both sides of the CNC lathe's forward and reverse tool post, so that the side of the load-bearing plate can abut against the two tool holders on both sides of the CNC lathe's forward and reverse tool post.

[0009] A stiffening plate assembly is provided at the connection between the base plate and the load-bearing plate;

[0010] The end of the load-bearing plate opposite to the base plate is the mounting end. The mounting end is used to extend out of the tool holder end of the forward and reverse tool post of the CNC lathe. The mounting end is provided with a first baffle and a second baffle on opposite sides along the feed direction of the lathe. The first baffle and the second baffle are used to cooperate in clamping the long tool row.

[0011] By adopting the above technical solution, without damaging the machine tool equipment, the housing of the positive and negative tool post serves as the base plate fixing point, and the tool holders on both sides of the positive and negative tool post achieve overall tooling limitation. Furthermore, the connection reliability between the load-bearing plate and the base plate is strengthened by the rib plate assembly, which ensures the rigidity and stability requirements of the long tool rack during the processing. This allows for the processing of large blind holes in workpieces using existing machine tool equipment, greatly reducing production costs. In addition, the long tool rack is clamped by the first and second baffles at the mounting end of the load-bearing plate, improving the installation stability of the long tool rack and ensuring processing reliability.

[0012] In some embodiments, the load-bearing plate has a first surface and a second surface facing away from each other, and the first baffle and the second baffle are disposed on the first surface;

[0013] The stiffening plate assembly includes a first stiffening plate assembly located on the first surface and a second stiffening plate assembly located on the second surface;

[0014] The first stiffener assembly includes a plurality of rectangular stiffeners arranged in a cross pattern, and the width of the first stiffener assembly is the same as the width of the load-bearing plate, so that the side of the first stiffener assembly can abut against the two sides of the tool holders of the CNC lathe's forward and reverse tool post.

[0015] The second stiffener assembly includes a plurality of triangular stiffeners arranged side by side, and one side of one of the adjacent sides of the triangular stiffeners of the second stiffener assembly is connected to the base plate, the other side is connected to the second surface of the load-bearing plate, and extends to the mounting end of the load-bearing plate.

[0016] By adopting the above technical solution, the reliability of the connection between the base plate and the load-bearing plate is further improved by using first and second stiffening plate assemblies with different structures on the two sides of the connection. Furthermore, the multiple rectangular stiffening plates of the first stiffening plate assembly, which are arranged horizontally and vertically, are more compact and smaller in size while ensuring strength, making them suitable for the limited usable area of ​​the first surface of the load-bearing plate. At the same time, their sides are more suitable for abutting against the tool holders on both sides. By abutting against the tool holders on both sides with the side of the first stiffening plate assembly, the limiting effect of the tool holders on the overall tooling is further improved, avoiding vibration when the long row of tools is working. Meanwhile, the multiple triangular stiffening plates of the second stiffening plate assembly can balance cost and rigidity requirements, effectively controlling the tooling manufacturing cost.

[0017] In some embodiments, the rectangular stiffeners arranged laterally in the first stiffener assembly are parallel to the base plate, and the side of the first stiffener assembly facing away from the base plate is the rectangular stiffener.

[0018] The first stiffener assembly further includes a triangular stiffener, which is disposed on the side of the first stiffener assembly away from the base plate and connected to the first surface of the load-bearing plate.

[0019] In some embodiments, a plurality of pressure plates are also included, which are positioned on the side of the long blade row away from the load-bearing plate and clamp the long blade row by means of locking members cooperating with the load-bearing plate.

[0020] By adopting the above technical solution, the upper and lower limits of the long blade row are achieved through the cooperation of the pressure plate and the load-bearing plate, which reduces and further improves the installation stability of the long blade row and ensures the reliability of processing.

[0021] In some embodiments, a third rib assembly is provided on the side of the first baffle away from the second baffle, the third rib assembly including a plurality of triangular ribs arranged side by side;

[0022] A portion of the triangular ribs in the third rib assembly are correspondingly disposed with the plurality of pressure plates, and the side of the triangular ribs extends to the top of the first baffle.

[0023] By adopting the above technical solution, the load-bearing capacity and stability of the first baffle are improved by the third stiffener assembly, and the clamping stability of the first baffle and the second baffle on the long blade row is improved.

[0024] In some embodiments, the load-bearing plate, the first baffle, and the second baffle are each provided with a plurality of through holes, which cooperate with the through holes on the long blade row to connect the long blade row to the load-bearing plate, the first baffle, and the second baffle through a connector.

[0025] By adopting the above technical solution, the long blade bar is connected to the load-bearing plate, the first baffle and the second baffle through the through hole of the connector, which further improves the installation stability of the long blade bar.

[0026] In some embodiments, the base plate, the load-bearing plate, the first baffle, the second baffle, and the stiffening plate assembly are all steel plates and are connected by welding.

[0043] Please see Figure 1 , Figure 1 For the existing CNC horizontal lathe's forward and reverse tool post.

[0044] The CNC lathe is equipped with forward and reverse tool posts, which include a housing 1 and two tool holders 2 located on both sides of the housing 1.

[0045] Please see Figure 2-4 , Figure 2 This is a schematic diagram of the structure of an embodiment of this application, in which the first baffle 21 is omitted; Figure 3 This is a schematic diagram illustrating the usage state of an embodiment of this application; Figure 4 This is a schematic diagram showing another perspective of the usage state of an embodiment of this application.

[0046] This application provides a long tool rack fixture for forward and reverse tool holders of a CNC horizontal lathe, including a base plate 10 and a load-bearing plate 20 perpendicularly connected to the base plate 10.

[0047] The base plate 10 is used to detachably connect to the housing 1 of the forward and reverse tool post of the CNC horizontal lathe, for example by bolt connection, so that the load-bearing plate 20 can be located between the two tool holders 2 on both sides of the forward and reverse tool post of the CNC horizontal lathe, thereby realizing the installation of this tooling without damaging the machine tool equipment.

[0048] The width of the load-bearing plate 20 is adapted to the spacing between the two tool holders 2 on both sides of the CNC horizontal lathe's forward and reverse tool post, so that the side of the load-bearing plate 20 can abut against the two tool holders 2 on both sides of the CNC horizontal lathe's forward and reverse tool post. This allows the tooling to be fully limited by the two tool holders 2 on both sides of the forward and reverse tool post, improving working stability and preventing vibration.

[0049] It should be noted that the base plate 10 and the housing 1 are detachably connected, for example with bolts. Although this does not damage the original function of the machine tool, it is difficult to fix the connection tightly. This causes the long tool rack 5 to vibrate when it is working, especially when the machine tool is machining through holes or blind holes. The vibration of the long tool rack 5 is mainly generated in its feed direction. Therefore, by limiting the two sides of the tool holder 2 of the original tool post of the machine tool, the stability of the long tool rack 5 can be further ensured.

[0050] In one embodiment, a stiffening plate assembly is provided at the connection between the base plate 10 and the load-bearing plate 20, which enhances the reliability of the connection between the load-bearing plate 20 and the base plate 10, ensuring the rigidity and stability requirements of the long cutter bar 5 during the processing, enabling the processing of large blind holes in workpieces using existing machine tools, and greatly reducing production costs.

[0051] In one embodiment, the end of the load-bearing plate 20 away from the base plate 10 is the mounting end. The mounting end is used to extend out of the end of the tool holder 2 of the CNC lathe's forward and reverse tool holders. The mounting end is provided with a first baffle 21 and a second baffle 22 on opposite sides along the lathe's feed direction. The first baffle 21 and the second baffle 22 are used to cooperate in clamping the long tool row 5, improving the installation stability of the long tool row 5 and ensuring machining reliability.

[0052] It should be noted that when the base plate 10 and the box 1 are connected by bolts, the load-bearing capacity of this fixture mainly relies on the bolts between the base plate 10 and the box 1 behind it. It is necessary to calculate the bolt stress, the size and number of bolts used, and ensure that the bolts and the box 1 can fully bear the weight of the fixture.

[0053] Meanwhile, those skilled in the art know that in order to achieve machining, it is necessary to consider the rotation center and center height of the machine tool. In actual use, it is necessary to measure the rotation center and center height of the machine tool, set the appropriate length of the load-bearing plate 20 and the appropriate connection position of the base plate 10 to the housing 1, so that the mounting end of the load-bearing plate 20 is located at the machining position, that is, when the long tool rack 5 is installed, the long tool rack 5 passes through the rotation center of the machine tool and the tool tip is located at the center height of the machine tool.

[0054] In one embodiment, the load-bearing plate 20 has a first surface and a second surface facing away from each other, and a first baffle 21 and a second baffle 22 are disposed on the first surface.

[0055] The stiffening plate assembly includes a first stiffening plate assembly 30 located on a first surface and a second stiffening plate assembly 40 located on a second surface.

[0056] The first stiffener assembly 30 includes a plurality of rectangular stiffeners 3 arranged in a cross pattern, and the width of the first stiffener assembly 30 is the same as the width of the load-bearing plate 20, so that the side of the first stiffener assembly 30 can abut against the two sides of the tool holders 2 of the forward and reverse tool holders of the CNC lathe.

[0057] The second stiffener assembly 40 includes a plurality of triangular stiffeners 4 arranged side by side, and one side of one of the adjacent sides of the triangular stiffeners 4 of the second stiffener assembly 40 is connected to the base plate 10, the other side is connected to the second surface of the load-bearing plate 20, and extends to the mounting end of the load-bearing plate 20.

[0058] In this method, the reliability of the connection between the base plate 10 and the load-bearing plate 20 is further improved by using a first stiffener assembly 30 and a second stiffener assembly 40 with different structures respectively on the two sides of the connection between the base plate 10 and the load-bearing plate 20.

[0059] Furthermore, the multiple rectangular ribs arranged horizontally and vertically in the first rib assembly 30 ensure strength while making the structure more compact and smaller in size, which is suitable for the limited usable area of ​​the first surface of the load-bearing plate 20. At the same time, its side is more suitable for abutting against the two tool holders 2. By abutting against the two tool holders 2 with the side of the first rib assembly 30, the overall limiting effect of the two tool holders 2 on the tooling is further improved, avoiding vibration when the long row of tools is working.

[0060] The multiple triangular stiffeners 4 of the second stiffener assembly can balance cost and rigidity requirements, effectively controlling the tooling manufacturing cost.

[0061] In one embodiment, the rectangular stiffeners 3 arranged laterally in the first stiffener assembly 30 are parallel to the base plate 10, and the side of the first stiffener assembly 30 facing away from the base plate 10 is a rectangular stiffener 3.

[0062] The first stiffener assembly 30 also includes a triangular stiffener 4. The triangular stiffener 4 of the first stiffener assembly 30 is disposed on the side of the first stiffener assembly 30 away from the bottom plate 10 and is connected to the first surface of the load-bearing plate 20, further enhancing the strength of the connection between the bottom plate 10 and the first surface of the load-bearing plate 20.

[0063] In one embodiment, the fixture also includes multiple pressure plates 60, which are placed on the side of the long cutter bar 5 away from the load-bearing plate 20 and clamp the long cutter bar 5 in cooperation with the load-bearing plate 20 through locking members 61. The cooperation between the pressure plates 60 and the load-bearing plate 20 achieves the upper and lower limit of the long cutter bar 5, thereby reducing and further improving the installation stability of the long cutter bar 5 and ensuring the reliability of processing.

[0064] In one embodiment, a third stiffener assembly 50 is provided on the side of the first baffle 21 opposite to the second baffle 22. The third stiffener assembly 50 improves the load-bearing capacity and stability of the first baffle 21, and improves the clamping stability of the first baffle 21 and the second baffle 22 on the long blade row 5.

[0065] In one specific embodiment, the third stiffener assembly 50 includes a plurality of triangular stiffeners 4 arranged side by side. Some of the triangular stiffeners 4 in the third stiffener assembly 50 are correspondingly arranged with a plurality of pressure plates 60, and the side of the triangular stiffeners 4 extends to the top of the first baffle 21.

[0066] In one embodiment, the load-bearing plate 20, the first baffle 21, and the second baffle 22 are all provided with multiple through holes, which cooperate with the through holes on the long blade row 5 so that the long blade row 5 can be connected to the load-bearing plate 20, the first baffle 21, and the second baffle 22 through the connector, thereby further improving the installation stability of the long blade row 5.

[0067] In one embodiment, the base plate 10, the load-bearing plate 20, the first baffle 21, the second baffle 22, and the stiffening plate assembly are all steel plates and are connected by welding, which can ensure the rigidity of the tooling and the connection is stable.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
