Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ductile iron machine tools, specifically to a ductile iron machine tool bed anti-deformation device. Background Technology
[0002] In the field of modern machining, ductile iron machine tools are widely used in the processing and manufacturing of various precision parts due to their unique advantages, such as high strength, good wear resistance and relatively low cost.
[0003] When a machine tool is running, the cutting process generates a large amount of heat. The coefficient of thermal expansion of ductile iron is relatively large. Different parts of the machine bed will experience uneven thermal expansion and contraction due to temperature changes, which will lead to thermal stress. Therefore, devices for preventing deformation of ductile iron machine tool beds have emerged on the market. However, although the common circulating water cooling system has a good cooling effect, it has problems such as water leakage, scaling, and corrosion. Not only is the maintenance cost high, but uneven cooling may also lead to local thermal stress concentration, which may cause deformation of the machine bed. At the same time, the existing cooling methods will still rapidly cool down the machine tool after it has been used for a period of time and then stopped. Rapid cooling after the machine tool is stopped may lead to thermal stress concentration, loss of accuracy, and accelerated wear of parts, which may affect the subsequent use of the machine tool.
[0004] To address the aforementioned issues, this application proposes an anti-deformation device for the bed of a ductile iron machine tool. Summary of the Invention
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a device for preventing deformation of the bed of a ductile iron machine tool.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ductile iron machine tool bed anti-deformation device, comprising a lower bed plate and an upper bed plate, wherein a first groove is provided on the top of the lower bed plate, a second groove is provided on the bottom of the upper bed plate, and a heat dissipation component is provided on the lower bed plate;
[0007] The heat dissipation assembly includes a lower outer shell fixedly connected to a lower bed plate via a first groove, a slot being provided on the top of the lower outer shell, an upper outer shell being fixedly connected to the bottom of an upper bed plate, an insert being fixedly connected to the bottom of the upper outer shell, the outer wall of the insert fitting into the slot provided in the lower outer shell, a water inlet pipe being slidably connected to the lower bed plate, a connecting pipe being fixedly connected to the water inlet pipe, a water outlet pipe being fixedly connected to the end of the connecting pipe away from the water inlet pipe, a sealing cap being movably connected to the end of the water inlet pipe located outside the lower bed plate, and a fixing assembly being provided on the outer wall of the lower bed plate.
[0008] In a preferred embodiment, the fixing assembly includes a first ear plate fixedly connected to the outer wall of the lower bed board, a second ear plate fixedly connected to the outer wall of the upper bed board, a bolt rotatably connected to the upper part of the first ear plate, a nut threadedly connected to the bottom of the bolt, the top of the nut fitting against the bottom of the first ear plate, and an anti-slip pad rotatably connected to the outer wall of the bolt, the bottom of the anti-slip pad fitting against the top of the second ear plate.
[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the first ear plate, the second ear plate, the bolts and nuts, the lower bed plate and the upper bed plate can be separated and merged, avoiding damage to the components in the heat dissipation assembly and affecting the cooling of the machine tool. Furthermore, through cooperation with the anti-slip pad, the bolts are limited, preventing them from affecting the merging of the lower bed plate and the upper bed plate.
[0010] In a preferred embodiment, a sealing block is fixedly connected to the sealing cover, the outer wall of the sealing block is in contact with the inner wall of the lower outer shell, the outer wall of the sealing block is in contact with the inner wall of the upper outer shell, and a baffle is fixedly connected to the outer wall of the water outlet pipe, one side of the baffle is in contact with the outer wall of the upper outer shell, and the other side of the baffle is in contact with the outer wall of the lower outer shell.
[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the sealing block and the baffle, the lower shell and the upper shell located at the water outlet end and the closed end are sealed, thereby avoiding water leakage from the water pipe where the lower shell and the upper shell are combined.
[0012] In a preferred embodiment, a support member is rotatably connected to the outer wall of the connecting pipe, the outer wall of the support member being in contact with the inner wall of the lower outer shell, and the outer wall of the support member being in contact with the inner wall of the upper outer shell.
[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the support, the connecting pipe is limited, thus avoiding affecting the heat dissipation of the machine tool bed.
[0014] In a preferred embodiment, a sealing gasket is fixedly connected to the bottom of the insert, and the bottom of the sealing gasket fits into a slot in the lower housing.
[0015] The technical effect of adopting the above-mentioned further solution is that, under the action of the support, the sealing of the contact point between the insert and the slot is achieved, thus avoiding affecting the cooling of the machine tool bed.
[0016] This utility model provides a device for preventing deformation of the bed of a ductile iron machine tool. It has the following beneficial effects:
[0017] When the machine tool is in use, the water inside the upper housing and slots absorbs the heat generated during operation. The heat absorbed by the water is transferred out of the machine tool area through the coolant inside the inlet pipe, connecting pipe, and outlet pipe, thus cooling the machine tool. When the machine tool is not in use, the water inside the slots and upper housing absorbs the residual heat of the machine tool and slowly releases it, thereby reducing the generation of thermal stress and preventing deformation and damage to the machine tool bed.
[0018] By setting a fixing component, the lower bed plate and the upper bed plate can be separated and merged. When it is necessary to replace the components in the heat dissipation assembly, the bolts can be removed from the first ear plate and the second ear plate by rotating the nut. At this time, the lower bed plate and the upper bed plate can be separated. The components in the lower bed plate can be disassembled and replaced by separating the lower bed plate and the upper bed plate, thereby avoiding damage to the components in the heat dissipation assembly and affecting the cooling of the machine tool.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: including a lower bed plate 1 and an upper bed plate 2, the lower bed plate 1 and the upper bed plate 2 are adapted to each other to form the bed of the machine tool, a first groove 3 is provided on the top of the lower bed plate 1, a second groove 4 is provided on the bottom of the upper bed plate 2, and a heat dissipation component 5 is provided on the lower bed plate 1. The cooperation of the first groove 3 and the second groove 4 can facilitate the placement of the heat dissipation component 5.
[0030] The heat dissipation assembly 5 includes a lower outer shell 501 fixedly connected to the lower bed plate 1 via a first groove 3. A slot 502 is provided on the top of the lower outer shell 501. An upper outer shell 506 is fixedly connected to the bottom of the upper bed plate 2. The lower outer shell 501 and the upper outer shell 506 are compatible and can accommodate water. A plug 508 is fixedly connected to the bottom of the upper outer shell 506. The plug 508 can be inserted into the slot 502 to prevent water loss from the pipe formed by the lower outer shell 501 and the upper outer shell 506. The outer wall of the plug 508 fits snugly against the slot 502 in the lower outer shell 501. A water inlet pipe 503 is slidably connected to the lower bed plate 1. The inlet pipe 503 is used to connect to the coolant tank and to transmit the coolant. A connecting pipe 504 is fixedly connected to the inlet pipe 503. The connecting pipe 504 is used to transmit the coolant and absorb the heat generated by the machine tool. The end of the connecting pipe 504 away from the inlet pipe 503 is fixedly connected to the outlet pipe 505. The outlet pipe 505 can transfer the heat-absorbing coolant away from the machine tool. A sealing cover 507 is movably connected to the end of the inlet pipe 503 located outside the lower bed plate 1. The sealing cover 507 is used to seal the pipe formed by the lower outer shell 501 and the upper outer shell 506. A fixing component 6 is provided on the outer wall of the lower bed plate 1.
[0031] Furthermore, such as Figure 1 - Figure 5As shown: The fixing assembly 6 includes a first ear plate 601 fixedly connected to the outer wall of the lower bed plate 1, and a second ear plate 602 fixedly connected to the outer wall of the upper bed plate 2. A bolt 603 is rotatably connected to the upper part of the first ear plate 601, and a nut 604 is threadedly connected to the bottom of the bolt 603. The top of the nut 604 is in contact with the bottom of the first ear plate 601. An anti-slip pad 605 is rotatably connected to the outer wall of the bolt 603. The bottom of the anti-slip pad 605 is in contact with the top of the second ear plate 602. Under the action of the first ear plate 601, the second ear plate 602, the bolt 603, and the nut 604, the lower bed plate 1 and the upper bed plate 2 can be separated and merged, avoiding damage to the components in the heat dissipation assembly 5 and affecting the cooling of the machine tool. Furthermore, through the cooperation with the anti-slip pad 605, the bolt 603 is limited, preventing it from affecting the merging of the lower bed plate 1 and the upper bed plate 2.
[0032] The above solution also has the problem of water leakage at both ends of the water pipe where the upper outer casing 506 and the lower outer casing 501 are combined, such as... Figure 2 and Figure 3 As shown: A sealing block 509 is fixedly connected to the sealing cover 507. The outer wall of the sealing block 509 is in contact with the inner wall of the lower outer shell 501 and the inner wall of the upper outer shell 506. A baffle 511 is fixedly connected to the outer wall of the water outlet pipe 505. One side of the baffle 511 is in contact with the outer wall of the upper outer shell 506 and the other side of the baffle 511 is in contact with the outer wall of the lower outer shell 501. Under the action of the sealing block 509 and the baffle 511, the lower outer shell 501 and the upper outer shell 506 are sealed at the water outlet and closed ends, thereby preventing water leakage from the water pipes of the lower outer shell 501 and the upper outer shell 506.
[0033] The above solution also has the problem of support component 510 wobbling, such as... Figure 3 As shown, a support member 510 is rotatably connected to the outer wall of the connecting pipe 504. The outer wall of the support member 510 is in contact with the inner wall of the lower outer shell 501 and the outer wall of the support member 510 is in contact with the inner wall of the upper outer shell 506. Under the action of the support member 510, the connecting pipe 504 is limited to avoid affecting the heat dissipation of the machine tool bed.
[0034] The above solution still has the problem of water leaking out through the contact point between slot 502 and insert 508, such as... Figure 2 As shown, a sealing gasket 512 is fixedly connected to the bottom of the insert 508. The bottom of the sealing gasket 512 fits into the slot 502 opened in the lower housing 501. Under the action of the sealing gasket 512, the fitting point between the insert 508 and the slot 502 is sealed, thus preventing any impact on the cooling of the machine tool bed.
[0035] Working principle:
[0036] like Figure 1-5 As shown:
[0037] During use: Before using the machine tool, fill the upper housing 506 and slot 502 with clean water, and seal the pipe formed by the upper housing 506 and slot 502 with sealing cover 507. During operation, the water inside the anti-slip pad 605 and slot 502 absorbs the heat generated by the machine tool. The heat absorbed by the water is transferred out of the machine tool area through the coolant inside the inlet pipe 503, connecting pipe 504, and outlet pipe 505, thus cooling the machine tool. When the machine tool is not in use, the coolant inside the slot 502 and upper housing 506... Clean water absorbs residual heat from the machine tool and releases it slowly, thereby reducing thermal stress and preventing deformation or damage to the machine tool bed. When it is necessary to replace the components in the heat dissipation assembly 5, the bolts 603 can be removed from the first ear plate 601 and the second ear plate 602 by rotating the nut 604. At this time, the lower bed plate 1 and the upper bed plate 2 can be separated. The components in the lower bed plate 1 can be disassembled and replaced by separating the lower bed plate 1 and the upper bed plate 2, thereby preventing damage to the components in the heat dissipation assembly 5 and affecting the cooling of the machine tool.
