Description

Technical Field

[0001] The utility model belongs to the technical field of machine processing, and in particular relates to a tool used for modular composite processing of machine tool parts. Background Art

[0002] The main components of large machine tools, including the bed, columns, cross rails, work tables, etc., generally need to be completed on large gantry machining centers. The structures of these components have their own characteristics. Most of them are special-shaped parts with large differences in external dimensions, and they have high requirements for processing and equipment travel. For example, the workbench is a flat part with a thin thickness. It requires enough support points and a smaller equipment travel to ensure that the processing spindle head is as close to the processing work surface as possible; and the height of the cross rail is high, so the equipment needs to have enough travel to meet the processing requirements on the front and all sides. At the same time, due to the structural and volume characteristics of the large gantry machining center, as well as the limited load-bearing capacity of the workbench itself, when processing these machine tool parts, the tooling design should be simplified as much as possible. The application of modular composite tooling has become a top priority in order to meet the clamping and positioning requirements and reduce weight as much as possible.

[0003] Due to the structural differences between different machine tool components and the relative fixedness of the equipment structure, to process a set of machine tool components, multiple devices and fixtures, or even special equipment, are required. However, the batch size of such large machine tool components is generally not too large, so the following pressures are imposed on the processing unit:

[0004] 1. The investment cost of purchasing equipment is high, and the pressure of cost recovery is high;

[0005] 2. The tooling clamps are large in size and quantity, occupying more space resources;

[0006] 3. The batch size of such parts is not large, resulting in idle equipment and fixtures;

[0007] 4. The parts processed by different equipment have different benchmarks and precisions, which can easily cause large cumulative errors. Utility Model Content

[0008] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a tooling for modular composite processing of machine tool components to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tooling for modular composite processing of machine tool components, including a machine tool workbench, a modular platform, a first support block, a first top screw, a machine tool cross rail, a second top screw, a second support block, a first double-headed screw, a pressure plate, a second double-headed screw, a third double-headed screw and an equal height block. There are six sets of modular platforms, which have the same characteristics on the opposite sides. There are three types of mounting surfaces A, B and C that can be selected for the basic pad platform. When used for the processing of the machine tool cross rail, the C surface of the modular platform is connected to the machine tool workbench by a pin key, a T-nut and a bolt. The B surface of the modular platform on the left faces forward, and the A surface of the modular platform on the right faces forward.

A nut washer and two locking nuts are installed on the third double-headed screw for pressure plate support, and a nut washer and a locking nut are installed on the second double-headed screw for pressure plate clamping, so as to fix both sides of the machine tool cross rail.

[0012] Preferably, two supporting pads are fixed on the left and right modular platforms respectively, and a supporting top screw is installed on each supporting pad to realize the support on both sides of the machine tool cross rail.

[0013] Preferably, there are four equal-height blocks, which act on the bottom of the machine tool components respectively to support the machine tool components.

[0014] Preferably, when used for machining the machine tool cross rail, eight first support blocks are arranged and distributed at the bottom of the machine tool cross rail, four of which are used for positioning and four for positioning and support.

[0015] Preferably, when the four first support blocks are used for positioning, they are connected to the machine tool worktable through hexagon socket bolts and are respectively distributed at four positions of the front, back, left and right of the bottom of the machine tool cross rail. A first top screw is installed thereon to achieve front and back positioning of the machine tool cross rail.

[0016] Preferably, when the four first support blocks are used for positioning and supporting, they are connected to the machine tool worktable through hexagon socket bolts, and the second top screw and pad are installed on the first support block. When working, the two edges of the second support block are in contact with the second top screw and the pad respectively, thereby realizing the positioning and support of the bottom slope of the machine tool cross rail.

[0017] Preferably, the second supporting block is made of aluminum.

[0018] Preferably, when used for processing the machine tool cross rail, eight first double-headed screws are required, which are distributed in four directions of front, back, left and right of the bottom of the machine tool cross rail. Four of the first double-headed screws are respectively combined with a nut washer and two locking nuts to be used as pressure plate supports, and the other four first double-headed screws are respectively combined with a nut washer and a locking nut to be used as pressure plate clamping, thereby achieving clamping of the bottom of the machine tool cross rail.

The precision of individual products and the precision of complete assembly have been greatly improved. No additional fixture placement space is required on site, which improves equipment utilization. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Refer to the following Figure 1-Figure 2 To describe a tool for modular composite processing of machine tool components provided by one embodiment of the present application.

[0031] A tool for modular composite processing of machine tool parts, including a machine tool workbench 1, a modular platform 2, a first support block 3, a first top screw 4, a machine tool cross rail 7, a second top screw 8, a second support block 10, a first double-headed screw 13, a pressure plate 14, a second double-headed screw 16, a third double-headed screw 17 and an equal height block 15, totaling more than 50 kinds of fixture components. The size range of the fixture and the workpiece to be processed is: length 1000-13000 (mm), width 500-3000 (mm), height 200-1500 (mm). The included fixture components can be used separately or can be assembled and deployed in a portable manner. Through pin keying The structure ensures that the module has reliable repeat positioning accuracy, especially the modular platform 2 has convenient and efficient installation, high form and position accuracy and repeat positioning accuracy and rigidity. Other fixtures can be installed on the platform in a portable manner and can provide sufficient accuracy and stability. When processing flat parts such as workbenches, the modular platform 2 is spliced ​​and installed on the machine tool workbench 1. When processing parts with higher heights, the modular platform 2 is removed to meet the processing range required by various machine tool parts. There are six sets of modular platforms 2, which have the same characteristics on the opposite sides. There are three types of installation surfaces A, B, and C to choose from for the basic pad platform to meet the height requirements of processing different machine tool parts.

[0032] When used for machining the machine tool cross rail 7, the C surface of the modular platform 2 is connected to the machine tool worktable 1 through a pin key, a T-nut and a bolt, and the left modular platform 2B faces forward, while the right modular platform 2A faces forward.

[0033] Furthermore, two first support blocks 3 are respectively installed on the left and right modular platforms 2 through hexagon socket bolts 18, and the first support blocks 3 are installed with first top screws 4 for realizing lateral positioning of the machine tool cross rail 7.

[0034] Furthermore, a third double-headed screw 17 and a second double-headed screw 16 are respectively fixed on the left and right modular platforms 2. The third double-headed screw 17 is equipped with a nut gasket 12 and two locking nuts 11 for supporting the pressure plate 14, and the second double-headed screw 16 is equipped with a nut gasket 12 and a locking nut 11 for tightening the pressure plate 14, so as to fix the two sides of the machine tool cross rail 7.

[0035] Furthermore, two support blocks 6 are fixed on the left and right modular platforms 2 respectively, and a support top screw 5 is installed on each of the support blocks 6 to achieve support on both sides of the machine tool cross rail 7.

[0036] Furthermore, there are four contour blocks 15, which act on the bottom of the machine tool components respectively for supporting the machine tool components. The lateral distance between the contour blocks 15 and the two ends of the machine tool components being processed is the total length of the workpiece × 0.22. It has been verified that this distance allows the machine tool components to be located most stably.

[0037] Furthermore, when used for machining the machine tool cross rail 7, eight first support blocks 3 are provided and distributed at the bottom of the machine tool cross rail 7, four of which are used for positioning, and four of which are used for positioning and supporting.

[0038] In a further embodiment, when the four first support blocks 3 are used for positioning, they are connected to the machine tool worktable 1 through the hexagon socket bolts 18, and are respectively distributed at four positions of the front, back, left and right of the bottom of the machine tool cross rail 7, and the first top screw 4 is installed thereon to realize the front and back positioning of the machine tool cross rail 7.

[0039] In a further embodiment, when the four first support blocks 3 are used for positioning and supporting, they are connected to the machine tool worktable 1 through the hexagon socket bolts 18, and the second top screw 8 and the cushion block 9 are installed on the first support block 3. When working, the two edges of the second support block 10 are in contact with the second top screw 8 and the cushion block 9 respectively, thereby realizing the positioning and support of the bottom slope of the machine tool cross rail 7.

[0040] In a further embodiment, the material of the second support block 10 is not carbon steel, but aluminum which is light in weight, has good toughness and strong ductility. In view of these characteristics of aluminum itself, when the second support block 10 acts on the slope at the bottom of the machine tool cross rail 7, it can be closer to the slope than support blocks made of other materials, and can also play a role in shock absorption and fine-tuning, thereby more effectively positioning and supporting the machine tool cross rail 7.

[0041] In a further embodiment, when used for processing the machine tool cross rail 7, eight first double-headed screws 13 are required, which are distributed in the four directions of front, back, left and right of the bottom of the machine tool cross rail 7. Four of the first double-headed screws 13 are respectively combined with a nut washer 12 and two locking nuts 11 to be used as a pressure plate 14 for support, and the other four first double-headed screws 13 are respectively combined with a nut washer 12 and a locking nut 11 to be used as a pressure plate 14 for clamping, thereby achieving clamping of the bottom of the machine tool cross rail 7.

[0042] The specific working process of this application is summarized and described in combination with the above embodiments:

[0043] 1. First, study the machine tool component drawings and analyze the processing capabilities of existing machine tool equipment to see if multiple parts can be processed on one device.

[0044] Second, design the tooling to see if multiple parts can be assembled on one tooling. If not, design modular composite tooling as much as possible, and assemble tooling that meets the processing requirements of various machine tool parts by adjusting the relative positions of the components of the modular composite tooling.

[0045] 3. Connect the tooling to the correct position of the machine tool equipment, clamp and position the parts on the tooling for processing verification, and use effective measuring tools such as internal diameter micrometer, vernier caliper, lever micrometer, etc. to perform first-piece verification on the machine tool components. If the verification is qualified, it means that the tooling meets the requirements.

[0046] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
