Description

Technical Field

[0001] This utility model relates to the field of center frame technology, specifically to a bed frame structure for a CNC machine tool. Background Technology

[0002] A center rest is a type of bed frame commonly used on CNC machine tools. It is an auxiliary device used to enhance the rigidity of workpieces and the cutting stability during the machining of slender shaft parts. In use, the shaft parts need to pass through the center rest and abut against the three sets of abutment rods on the center rest to achieve a three-point enclosed support structure.

[0003] In response, Chinese patent application number CN202320449227.9 discloses a center frame fixing structure for a roll lathe. The center frame body includes an upper mounting frame and a lower mounting frame, both equipped with movable shafts and mounting blocks. The upper and lower mounting frames are provided with mounting grooves. The upper mounting frame is equipped with a first pad, and the lower mounting frame is equipped with a second pad. The first pad has a connecting hole, and the second pad has an insertion hole. A U-shaped reinforcing iron with mounting holes is fitted onto the mounting groove of the center frame body. This U-shaped reinforcing iron solves the problem that when the existing center frame is fixed to the mounting blocks with bolts, lathe wobbling can easily cause the bolts on the mounting blocks to loosen, affecting the clamping of the object by the clamping rod.

[0004] The center frame uses clamping rods to abut against the shaft. However, when the shaft is rotated, the clamping rods will rub against the shaft, which will scratch the shaft. Therefore, workers will apply lubricating oil to the part of the shaft surface that contacts the clamping rods. However, the lubricating oil will drip down the surface of the shaft, which can easily contaminate the equipment, increase the difficulty of cleaning, and cause inconvenience.

[0005] Therefore, in order to solve the above problems, a bed frame structure for CNC machine tools is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a bed frame structure for a CNC machine tool, in order to solve the problem mentioned in the background art that in the prior art, when the shaft is supported by a clamping rod, the clamping rod will rub against the shaft when the shaft rotates, which will scratch the shaft. Therefore, workers will apply lubricating oil to the part of the shaft surface that contacts the clamping rod, but the lubricating oil will drip down the surface of the shaft, which will easily contaminate the equipment, increase the difficulty of cleaning, and cause inconvenience.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bed frame structure for a CNC machine tool, comprising: a base, a movable frame mounted on the top surface of the base, an installation groove provided on the front side of the base, a connecting bolt inserted into the inner side of the installation groove, a limit plate provided on the lower side of the base, and clamping rods provided on the base and the movable frame;

[0008] The inner wall of the mounting groove is provided with a slot, the top surface of the base is provided with a guide groove, and a first magnetic block is attached to the center of the top surface of the base.

[0009] The base is equipped with a collection structure and a protective structure. The collection structure includes a collection box located in the center of the top surface of the base. A guide block is integrally formed on the bottom surface of the collection box, and a second magnetic block is bonded to the inside of the bottom surface of the collection box.

[0010] The protective structure includes a protective sleeve, which is movably installed inside the mounting groove, and a retaining strip is integrally formed on the outer wall of the protective sleeve.

[0011] Preferably, the connecting bolt passes through the base, the upper end of the connecting bolt is located inside the mounting groove, and the lower end of the connecting bolt is threadedly connected to the limiting plate.

[0012] Preferably, the collection box has an arc-shaped structure, the collection box is located on the lower side of the end of the clamping rod, the guide block is engaged inside the guide groove, and the second magnetic block is magnetically connected to the first magnetic block.

[0013] Preferably, the protective sleeve is fitted over the upper outer side of the connecting bolt, and the retaining strip is engaged inside the retaining groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing a collection box on the inner side of the base, the collection box is located on the lower side of the end of the clamping rod. When the clamping rod abuts against the shaft, the collection box can collect the dripping lubricating oil on the lower side, preventing the lubricating oil from dripping onto the equipment, keeping the equipment clean, and collecting the lubricating oil for unified treatment.

[0015] 1. This utility model features a protective structure. A limiting plate is installed inside the top surface of a machine tool, and then the base is moved to the machine tool so that it is positioned above the limiting plate. The connecting bolt is screwed into the mounting groove, and the bottom end of the connecting bolt is screwed into the inner side of the limiting plate, thereby fixing the base in a suitable position on the machine tool. Two sets of protective sleeves are inserted into the mounting groove from both sides. The protective sleeves are fitted over the upper outer side of the connecting bolts, which can protect the connecting bolts from corrosion between the upper end of the connecting bolts and the base. The retaining strip is locked inside the retaining groove. The retaining groove and retaining strip can position the protective sleeves inside the mounting groove, ensuring the stability of the protective sleeves inside the mounting groove.

[0016] 2. This utility model features a collection structure that secures the guide block inside the guide groove, allowing the collection box to be installed on the top surface of the base. The first magnetic block can magnetically connect with the second magnetic block, limiting the collection box's position on the base and preventing it from shifting and displacing during shaft rotation, thus ensuring effective lubrication collection.

[0027] The inner wall of the mounting groove 12 is provided with a slot 13, the top surface of the base 1 is provided with a guide groove 14, and the top surface of the base 1 is bonded with a first magnetic block 15.

[0028] A collection structure 2 and a protective structure 3 are installed on the base 1. The collection structure 2 includes a collection box 21, which is located in the middle of the top surface of the base 1. A guide block 22 is integrally formed on the bottom surface of the collection box 21. A second magnetic block 23 is bonded to the inside of the bottom surface of the collection box 21. The collection box 21 is located on the inner side of the base 1 and is located on the lower side of the end of the clamping rod 18. When the clamping rod 18 abuts against the shaft, the collection box 21 can collect the dripping lubricating oil on the lower side, preventing the lubricating oil from dripping onto the equipment, keeping the equipment clean, and collecting the lubricating oil for unified treatment.

[0029] The protective structure 3 includes a protective sleeve 31, which is movably installed inside the mounting groove 12. A retaining strip 32 is integrally formed on the outer wall of the protective sleeve 31.

[0030] Furthermore, the connecting bolt 16 passes through the base 1, with the upper end of the connecting bolt 16 located inside the mounting groove 12, and the lower end of the connecting bolt 16 threadedly connected to the limiting plate 17. The base 1 and the limiting plate 17 can be fixed in the lathe by the connecting bolt 16, making the movement and positioning of the base 1 convenient and applicable to the positioning needs of shafts of different lengths.

[0031] Furthermore, the collection box 21 has an arc-shaped structure and is located on the lower side of the end of the clamping rod 18. The guide block 22 is engaged inside the guide groove 14. The second magnetic block 23 is magnetically connected to the first magnetic block 15. The collection box 21 can collect lubricating oil dripping from the shaft on the lower side. The second magnetic block 23 cooperates with the first magnetic block 15 to provide positioning for the installation of the collection box 21.

[0032] Furthermore, the protective sleeve 31 is fitted onto the outer side of the upper end of the connecting bolt 16, and the retaining strip 32 is fitted into the inside of the retaining groove 13. The retaining strip 32, together with the retaining groove 13, provides positioning for the installation of the protective sleeve 31. The protective sleeve 31 can cover the connection between the connecting bolt 16 and the base 1 to prevent corrosion and improve the ease of movement of the base 1.

[0033] Working principle: During installation, first install the limiting plate 17 inside the top surface of the machine tool, then move the base 1 to the machine tool so that the base 1 is located above the limiting plate 17. Screw the connecting bolt 16 into the mounting groove 12. The bottom end of the connecting bolt 16 will be screwed into the inner side of the limiting plate 17, thereby fixing the base 1 in a suitable position on the machine tool. Insert the two sets of protective sleeves 31 into the inner side of the mounting groove 12 from both sides. The protective sleeves 31 will be fitted on the outer side of the upper end of the connecting bolt 16, which can shield and protect the connecting bolt 16 from corrosion between the upper end of the connecting bolt 16 and the base 1. The retaining strip 32 will be stuck in the inner side of the retaining groove 13. The retaining groove 13, together with the retaining strip 32, can position the installation of the protective sleeve 31 in the inner side of the mounting groove 12, ensuring the installation stability of the protective sleeve 31 in the inner side of the mounting groove 12.

[0034] The guide block 22 is snapped into the inside of the guide groove 14, which allows the collection box 21 to be installed on the top surface of the base 1. The first magnetic block 15 can be magnetically connected to the second magnetic block 23, which can limit the installation of the collection box 21 on the base 1 and prevent the collection box 21 from shaking and shifting when the shaft rotates, thus failing to achieve the ideal collection effect of lubricating oil. In use, the collection box 21 is located on the lower side of the ends of the three sets of clamping rods 18. Therefore, when the lubricating oil applied to the surface of the shaft drips, it will drip down into the collection box 21, which can prevent the lubricating oil from dripping onto the equipment, keep the equipment clean, and collect the lubricating oil for unified treatment.
