Description

TECHNICAL FIELD

[0001] The present application relates to the field of gap adjustment technology for machine tool parts, in particular to a machine tool beam slide and ram gap adjustment mechanism. BACKGROUND

[0002] Machine tools, as a kind of high-precision machining equipment, play a crucial role in modern manufacturing. With the increasing demand for part machining quality in industrial production, the design and manufacturing technology of machine tools are also constantly improving. Among them, the cooperation precision of the beam slide and ram, one of the key components of the machine tool, directly affects the working performance and machining efficiency of the entire machine tool. Reasonable structural design not only ensures the long-term stable operation of the machine tool, but also effectively improves the machining precision of the workpiece. In order to cope with the problem of thermal expansion and contraction caused by temperature changes in machine tools, various measures are generally taken in the industry to optimize the assembly relationship between the beam slide and the ram. For example, by selecting low-expansion coefficient materials to manufacture key components; using pre-tightening devices to compensate for possible dimensional deviations; and using manual adjustment tools to change the relative position of the two to achieve gap fine-tuning. These traditional solutions can alleviate the problem to some extent, but have great limitations in actual application and cannot fully meet the dynamic and refined operation requirements. However, most machine tools on the market still lack a flexible and effective mechanism to accurately control the distance between the beam slide and the ram, especially when facing different machining conditions, it is difficult to adapt in real time. This deficiency often leads to uneven gaps in the machine tool under working conditions, thereby affecting the overall machining effect and stability. CONTENT OF THE UTILITY MODEL

[0003] In order to further improve the machining precision of the machine tool, the present application provides a machine tool beam slide and ram gap adjustment mechanism.

[0004] The machine tool beam slide and ram gap adjustment mechanism provided by the present application adopts the following technical scheme:

[0005] A machine tool beam slide and ram gap adjustment mechanism, comprising a machine tool frame, a beam slide and a ram, further comprising a backing plate and an adjustment block, the beam slide is slidingly connected to the machine tool frame, an installation slot is formed in the beam slide, the ram is embedded in the installation slot, an adjustment slot is formed in the side wall of the beam slide on one side of the installation slot, the backing plate is installed at the opening of the adjustment slot at the upper end, a lifting bolt is installed on the backing plate, the adjustment block is installed in the installation slot, the lifting bolt is threadedly connected with the adjustment block, and the gap between the beam slide and the ram is adjusted by adjusting the position of the adjustment block.

[0006] By adopting the technical scheme, the gap between the beam slide plate and the ram can be effectively adjusted during the operation of the machine tool. Specifically, by cooperating the gasket, the lifting bolt and the adjusting block, the position of the adjusting block in the mounting groove can be accurately controlled, and the precise adjustment of the distance between the beam slide plate and the ram can be realized. This design can avoid excessive pressure or jamming between components caused by thermal expansion and contraction, thereby improving the overall stability and machining precision of the machine tool.

[0007] In a specific implementation scheme, a pushing screw is further included, which is rotationally connected to the gasket, and an end of the pushing screw away from the gasket abuts against an upper end surface of the adjusting block.

[0008] By adopting the technical scheme, more accurate gap adjustment between the beam slide plate and the ram can be achieved. Specifically, the pushing screw is added and rotationally connected to the gasket, so that the pushing screw can be flexibly adjusted in position, and the design of abutting against the upper end surface of the adjusting block further enhances the stability during adjustment. This structure not only improves the adjustment accuracy, but also effectively avoids the stress concentration problem that may be caused by excessive reliance on a single lifting bolt, thereby ensuring the stability and machining precision of the machine tool under different working conditions.

[0009] In a specific implementation scheme, two lifting bolts are provided, and the pushing screw is installed at the middle part of the gasket, and the two lifting bolts are symmetrically installed on both sides of the pushing screw.

[0010] By adopting the technical scheme, more accurate and stable gap adjustment effect can be achieved. Specifically, two lifting bolts are provided and symmetrically distributed on both sides of the pushing screw, so that the force distribution is more uniform, effectively avoiding the adjustment deviation problem caused by uneven stress at a single point, and improving the stability of the adjustment process. At the same time, the design of the pushing screw located at the middle position further optimizes the mechanical structure, which can better balance the interaction force between the beam slide plate and the ram during the adjustment process, so as to ensure that the gap between the two is always within the ideal range, thereby improving the overall machining precision and reliability of the machine tool.

[0011] In a specific implementation scheme, hexagonal nuts are installed on the upper ends of the pushing screw and the lifting bolt.

[0012] By adopting the technical scheme, hexagonal nuts can be added to the upper ends of the pushing screw and the lifting bolt, so that the operator can more conveniently use tools to rotate and adjust the bolts, improving the convenience and accuracy of adjustment. At the same time, the installation of the hexagonal nuts can also enhance the stability of the bolt connection, prevent the bolts from loosening due to vibration during the operation of the machine tool, and thus ensure the reliability of the gap adjustment between the beam slide plate and the ram.

[0013] In an embodiment, the adjusting block is a rectangular block, the adjusting groove is arranged obliquely opposite to the side wall of the ram, and is arranged obliquely from top to bottom in the installation direction of the ram.

[0014] By adopting the above technical scheme, the adjusting block is a rectangular block, which can ensure stable placement in the installation groove and avoid shaking or deviation caused by irregular shape. Meanwhile, the adjusting groove is arranged obliquely opposite to the side wall of the ram, and is arranged obliquely from top to bottom in the installation direction of the ram, so that the adjusting block can better adapt to the gap change requirement when stressed, thereby realizing more accurate gap adjustment effect.

[0015] In an embodiment, two adjusting grooves are arranged on the side wall of the beam slide plate on the same side of the installation groove, and the number of the gaskets, adjusting blocks, push screws and lifting bolts are correspondingly arranged.

[0016] By adopting the above technical scheme, two adjusting grooves are arranged, and the corresponding gaskets, adjusting blocks, push screws and lifting bolts are matched, which can realize double-point synchronous adjustment, effectively avoid the uneven stress caused by single-point adjustment, and further improve the cooperation precision between the ram and the beam slide plate. The design of multi-point support and adjustment helps to disperse stress, and can better maintain the stability of the machine tool structure under the condition of thermal expansion and contraction caused by temperature change, thereby improving the overall machining performance of the machine tool.

[0017] In an embodiment, a containing cavity is arranged on the side wall of the beam slide plate at the upper end of the adjusting groove, and the gasket is arranged in the containing cavity.

[0018] By adopting the above technical scheme, the position deviation or falling of the gasket during adjustment can be effectively prevented. The gasket is arranged in the containing cavity, which makes the gasket more stable and avoids loosening of the gasket caused by external vibration or other factors, thereby ensuring the stability of the entire gap adjustment mechanism and further improving the precision and reliability of the machine tool during machining.

[0019] In an embodiment, a pressing plate is arranged on the beam slide plate, and the pressing plate abuts the gasket in the containing cavity.

[0020] By adopting the above technical scheme, the pressing plate can firmly fix the gasket in the containing cavity, prevent the gasket from loosening or shifting during adjustment, and ensure the accuracy and stability of the position adjustment of the adjusting block. This design effectively improves the reliability of the gap adjustment between the beam slide plate and the ram, and further improves the precision and consistency of the machine tool machining.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] 1. By adding a gasket and an adjusting block between the beam slide and the ram, and using a tension bolt connection, the gap size between the two can be accurately adjusted, effectively solving the problem of thermal expansion and contraction caused by temperature changes, and improving the overall machining precision of the machine tool.

[0023] 2. The design of the adjusting block cooperating with the tension bolt allows the operator to flexibly adjust the gap according to actual processing needs, adapts to different processing conditions, and avoids the problem of uneven gap caused by traditional fixed design.

[0024] 3. The structure design of the installation groove and the adjusting groove is reasonable, which makes the adjusting process more stable and reliable, and reduces the possibility of jamming phenomenon in the adjusting process, and improves the stability of the machine tool operation.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] The embodiment of the present application discloses a machine tool beam slide and ram gap adjusting mechanism.

[0033] As Figures 1-3As shown in the drawings, the machine tool beam slide and ram gap adjusting mechanism comprises a machine tool frame 1, a beam slide 2, a ram 3, a pad plate 4 and an adjusting block 5, wherein the beam slide 2 is slidingly connected to the machine tool frame 1, the beam slide 2 is provided with a mounting groove 21, and the ram 3 is embedded in the mounting groove 21. In addition, the beam slide 2 is provided with an adjusting groove 22 on the side wall, the pad plate 4 is located above the adjusting groove 22 and is fixed to the outer surface of the beam slide 2 through a lifting bolt 6, and the adjusting block 5 is installed in the mounting groove 21 and is in threaded connection with the lifting bolt 6. By rotating the lifting bolt 6, the adjusting block 5 can be pushed to move in the horizontal direction, so as to adjust the relative position between the ram 3 and the beam slide 2, and achieve the ideal gap state.

[0034] As shown in the drawings, Figures 4-5 The pad plate 4 serves as a bearing component and plays a supporting role, and the material thereof can be selected from high-strength aluminum alloy or stainless steel plate to ensure sufficient strength and wear resistance. The pad plate 4 can be firmly installed on the corresponding area outside the beam slide 2 by welding or screw locking. For example, the pad plate 4 can be a steel plate with a thickness of 5-10 mm or an aluminum-magnesium alloy plate with equivalent strength, which has good flatness and corrosion resistance. For the lifting bolt 6, a standard M12-M20 specification full-thread finished bolt is preferably used, and a lock hex flange is added to the head of the bolt to facilitate the screwing operation of the operator. In order to prevent rusting during long-term use, it is recommended to perform zinc plating and passivation treatment on the surface.

[0035] The adjusting block 5 is designed in the form of a rectangular body, which is convenient to place in the pre-formed mounting groove 21. Considering various complex conditions that may be encountered in actual work, such as vibration impact force and other factors that may damage the originally set parameter value, high-density polyurethane foam plastic wrapped metal skeleton is recommended for material selection to make composite profile products. In this way, a certain rigidity is maintained while part of the external interference energy is absorbed, prolonging the service life and improving the stability of the overall system. For example, the adjusting block 5 can be made of high-quality carbon steel substrate covered with an elastic rubber layer to ensure that it can bear a certain load and has a flexible cushioning function.

The push screw 7 is vertically inserted into the central part of the pad plate 4 and is rotationally connected to the pad plate 4. A conical pressure head can be installed at the end of the push screw 7 to increase the contact area and help disperse stress concentration. Two lifting bolts 6 are symmetrically installed on both sides of the push screw.

[0037] The lateral wall of the beam slide 2 at the upper end of the adjusting groove 22 is provided with a containing cavity 23, the base plate 4 is installed in the containing cavity 23, and the beam slide 2 is provided with a pressing plate, the base plate 4 is pressed by the pressing plate and is installed in the containing cavity 23.

[0038] The implementation principle of the embodiment of the machine tool beam slide and ram gap adjusting mechanism is that the adjusting block 5 is moved along a predetermined track by adjusting the push screw 7 and the lifting screw, and the adjusting block 5 can extrude the ram 3 due to the inclined arrangement of the side wall of the adjusting groove 22 on one side, the relative position relationship between the beam slide 2 and the ram 3 is changed, and then the ideal distance value between the two is accurately set, so that the machining precision of the machine tool is further improved.

[0039] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: all equivalent changes made according to the structure, shape and principle of the application should be covered in the protection scope of the application.
