Description

Technical Field

[0001] This application relates to the field of support structures, and in particular to an auxiliary support device for screw rod installation. Background Technology

[0002] In the field of machine tool manufacturing and assembly, the lead screw, as a key transmission component, plays a crucial role in the overall performance of the machine tool due to its installation quality. The lead screw converts rotary motion into linear motion, providing precise displacement drive for the machine tool's worktable and other actuators. Its installation accuracy directly determines the machine tool's positioning accuracy, repeatability, and transmission accuracy, thus affecting the dimensional accuracy, shape accuracy, and surface quality of the machined workpiece.

[0003] However, in existing technologies, machine tools generally lack effective support measures when installing lead screws. Lead screws are typically quite long and have a certain weight, and under their own weight, the middle part of the lead screw is prone to sagging. This sagging phenomenon has a significant impact on the installation accuracy of the lead screw in the initial stage of installation, making it difficult to meet the design requirements for the geometric accuracy such as the parallelism and straightness of the lead screw axis with the machine tool guideway.

[0004] Meanwhile, existing lead screw support devices are mostly simple intermediate support blocks. Although they can support the lead screw, they usually do not have the function of assisting correction and improving installation accuracy, and their functions are relatively limited.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] This application provides an auxiliary support device for lead screw installation, which can solve the problem of how to reduce lead screw sagging and assist in correction and improvement of installation accuracy in the prior art.

[0007] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0008] A lead screw installation auxiliary support device is provided, the lead screw installation auxiliary support device comprising:

[0009] A support frame is provided with a V-shaped groove, the V-shaped groove has two symmetrical groove walls, the groove walls are inclined to the horizontal plane, and the V-shaped groove has an opening between the two groove walls, the opening is oriented upwards;

[0010] At least three support legs are provided on the support frame to support the support frame and to adjust the height of the support frame;

[0011] A buffer pad, with elastic deformation capability, covers the two groove wall surfaces of the V-shaped groove.

[0012] According to the above technical solution, the V-shaped groove on the support frame has two symmetrical groove walls inclined to the horizontal plane, with the opening facing upwards. When the lead screw is placed in the V-shaped groove, the lead screw contacts the two groove walls. This special structure of the V-shaped groove can provide stable support for the lead screw from two directions, limiting the sag tendency of the lead screw under gravity and distributing the weight of the lead screw to the two groove walls. Compared with planar support, it can effectively reduce the amount of sag generated by the lead screw under its own weight. At the same time, the buffer pads covering the surfaces of the two groove walls of the V-shaped groove have elastic deformation capabilities. When the lead screw is placed in the V-shaped groove, the buffer pads will elastically deform and closely fit the surface of the lead screw. This not only increases the contact area between the lead screw and the groove wall, but also further disperses the weight of the lead screw through elastic buffering, reducing the pressure on the lead screw in local positions, thereby helping to reduce the sag phenomenon caused by excessive local stress on the lead screw. The lead screw installation auxiliary support device also has an auxiliary correction function: the two walls of the V-groove are symmetrically arranged with a fixed tilt angle. When the lead screw is placed in the V-groove, the geometry of the V-groove can position the lead screw. If there is a slight offset or tilt during the placement process, the groove walls of the V-groove will restrict the lead screw's degree of freedom, guiding the lead screw to gradually adjust to the correct position, aligning its axis with the axis of symmetry of the V-groove, thus achieving initial correction of the lead screw. Simultaneously, at least three support feet located below the support frame can adjust the height of the support frame. During actual installation, if a horizontal or vertical deviation of the lead screw is found, adjusting the height of different support feet can change the tilt angle and horizontal position of the support frame, thereby adjusting the installation posture of the lead screw to achieve the ideal installation position and angle, achieving further correction of the lead screw installation position. The lead screw installation auxiliary support device improves installation accuracy: the stable support structure combining V-groove and buffer pad ensures the lead screw maintains a relatively stable position during installation, reducing minor displacements caused by external vibrations or its own weight. This provides a good foundation for precise lead screw installation and helps improve the positional accuracy of the lead screw installation. Simultaneously, by precisely adjusting the support feet, the lead screw can be adjusted to a position that precisely matches the relevant equipment or components, meeting high-precision installation requirements and further improving the overall accuracy of the lead screw installation. In summary, this lead screw installation auxiliary support device, through the synergistic effect of the V-groove structure, buffer pad, and support feet, effectively reduces lead screw sagging, assists in correcting the lead screw's installation position, and improves the lead screw's installation accuracy.

[0013] According to at least one embodiment of the present application, a lead screw installation auxiliary support device includes a support plate and an angle steel fixedly disposed on the upper end of the support plate, wherein the angle steel is provided with the V-shaped groove.

[0014] According to the technical solution of this embodiment, this support frame has a simple structure and is easy to manufacture. The V-shaped groove of the angle steel can provide stable support for the lead screw, while the support plate provides a basic support platform for the entire support frame, making the overall structure of the support frame stable and able to reliably support the lead screw, ensuring the stability of the lead screw during the installation process, and helping to improve the accuracy and quality of lead screw installation.

[0015] According to at least one embodiment of the lead screw installation auxiliary support device of this application, the support frame further includes a bracket, the bracket is detachably fixedly disposed on the upper end of the support plate, and is provided with an installation groove adapted to the bottom contour of the angle steel, the angle steel being fixedly disposed on the groove wall of the installation groove.

[0016] According to the technical solution of this embodiment, the detachable structure makes the assembly and disassembly of the angle steel and the support frame more convenient, facilitates transportation and storage, and allows for the replacement of angle steel of different specifications or types according to different installation requirements, thereby improving the versatility and flexibility of the device. It also makes it easier to replace damaged parts individually, reducing maintenance costs.

[0017] According to at least one embodiment of the present application, a lead screw installation auxiliary support device is provided with an open groove below the angle steel, and the bottom of the open groove is connected to the support plate by bolts, so that the support is detachably fixed to the upper end of the support plate.

[0018] According to the technical solution of this embodiment, the bolt connection method has a simple structure, is easy to operate, facilitates quick installation and disassembly of the bracket, and also ensures the connection strength and stability between the bracket and the support plate, thus ensuring the reliability of the overall structure of the support frame.

[0019] According to at least one embodiment of the present application, a lead screw mounting auxiliary support device is provided with a vertically extending stud on the support foot, and a support frame is provided with a screw hole adapted to the stud. The stud passes through the screw hole and is locked to the support frame by a nut.

[0020] According to the technical solution of this embodiment, the height of the support foot can be easily adjusted through this threaded connection, thereby achieving precise adjustment of the height of the support frame.

[0021] According to at least one embodiment of the lead screw installation auxiliary support device of this application, the support foot is provided with a base at the bottom end of the stud, and the base is used to increase the support area.

[0022] According to the technical solution of this embodiment, increasing the support area can improve the contact stability between the support foot and the ground, enhance the load-bearing capacity of the support device, and reduce the possibility of the support foot sinking or shaking due to uneven ground or excessive local stress, thereby ensuring the stability of the support frame.

[0023] According to at least one embodiment of the lead screw installation auxiliary support device of this application, the buffer pad is a rubber pad, the rubber pad is attached to the V-shaped groove, and the shape of its upper end face is the same as that of the V-shaped groove.

[0024] According to the technical solution of this embodiment, the rubber pad has good elastic deformation capability and buffering performance, which can effectively absorb the impact force generated when the lead screw is placed, reduce the rigid collision between the lead screw and the V-groove, and protect the surface of the lead screw from damage. At the same time, the rubber pad fits tightly with the V-groove, which can increase the friction between the lead screw and the V-groove, prevent the lead screw from sliding during installation, and further improve the stability and accuracy of the lead screw installation.

[0040] To address the technical problems in the background art, this embodiment provides an auxiliary support device for screw installation.

Figure 2 This is a front view of the lead screw installation auxiliary support device in the embodiments of this application. Figure 3 This is a perspective view of the lead screw being supported by the auxiliary support device for lead screw installation in the embodiments of this application.

[0042] See Figures 1 to 3 As shown, this embodiment provides a lead screw installation auxiliary support device, which includes: a support frame 100, a buffer pad 300, and at least three support feet 200.

[0043] See Figure 1 and Figure 2 As shown, the support frame 100 is provided with a V-shaped groove 110, which has two symmetrical groove walls 111. The groove walls 111 are inclined to the horizontal plane, and an opening 112 is provided between the two groove walls 111, with the opening 112 facing upwards. Support feet 200 are provided on the support frame 100 to support the support frame 100 and adjust its height. A buffer pad 300 has elastic deformation capability and covers the surfaces of the two groove walls 111 of the V-shaped groove 110.

[0044] See Figure 1 and Figure 3As shown, based on the above technical solution, the technical concept of this embodiment is that when the lead screw 400 is placed in the V-groove 110, the lead screw 400 contacts the two groove walls 111 of the V-groove 110. This special structure of the V-groove 110 can provide stable support for the lead screw 400 from two directions, limiting the drooping tendency of the lead screw 400 under the action of gravity and distributing the weight of the lead screw 400 to the two groove walls 111. Compared with planar support, this can effectively reduce the amount of drooping of the lead screw 400 under its own weight. At the same time, the buffer pad 300 will undergo elastic deformation and closely fit the surface of the lead screw 400. This not only increases the contact area between the lead screw 400 and the groove wall 111, but also further disperses the weight of the lead screw 400 through elastic buffering, reducing the pressure on the lead screw 400 in local positions, thereby helping to reduce the drooping phenomenon of the lead screw 400 caused by excessive local force. The aforementioned lead screw installation auxiliary support device also has an auxiliary correction function: when the lead screw 400 is placed in the V-groove 110, the geometry of the V-groove 110 can position the lead screw 400. If the lead screw 400 has a slight offset or tilt during placement, the groove wall 111 of the V-groove 110 will restrict the degree of freedom of the lead screw 400, guiding the lead screw 400 to gradually adjust to the correct position, aligning its axis with the axis of symmetry of the V-groove 110, thereby achieving initial correction of the lead screw 400. Simultaneously, at least three support feet 200 provided below the support frame 100 can adjust the height of the support frame 100. During actual installation, if a horizontal or vertical deviation of the lead screw 400 is found, adjusting the height of different support feet 200 can change the tilt angle and horizontal position of the support frame 100, thereby adjusting the installation posture of the lead screw 400 to achieve the ideal installation position and angle, achieving further correction of the lead screw 400's installation position. The aforementioned auxiliary support device for lead screw installation improves installation accuracy: the stable support structure combining the V-groove 110 and the buffer pad 300 ensures that the lead screw 400 maintains a relatively stable position during installation, reducing minor displacements caused by external vibrations or its own weight. This provides a good foundation for the precise installation of the lead screw 400 and helps improve its positional accuracy. Simultaneously, by precisely adjusting the support foot 200, the lead screw 400 can be adjusted to a position that precisely matches the relevant equipment or components, meeting high-precision installation requirements and further improving the overall installation accuracy of the lead screw 400. In summary, this auxiliary support device for lead screw 400 installation, through the synergistic effect of the V-groove 110 structure, the buffer pad 300, and the support foot 200, effectively reduces the sagging of the lead screw 400, assists in correcting the installation position of the lead screw 400, and improves the installation accuracy of the lead screw 400.

[0045] See Figure 1 and Figure 2As shown, the support frame 100 includes a support plate 120 and an angle steel 130 fixedly disposed on the upper end of the support plate 120. The angle steel 130 is provided with a V-groove 110. The support plate 120 can be an existing steel plate, which, combined with the angle steel 130, makes the support frame 100 simple in structure and easy to manufacture.

[0046] See Figure 1 and Figure 2 As shown, the support frame 100 further includes a bracket 140, which is detachably fixed to the upper end of the support plate 120 and has a mounting groove 141 that matches the bottom contour of the angle steel 130. The angle steel 130 is welded to the groove wall of the mounting groove 141 to achieve a stable connection. The detachable structure makes the assembly and disassembly of the angle steel 130 and the support frame 100 more convenient, facilitates transportation and storage, and allows for the replacement of different specifications or types of angle steel 130 according to different installation requirements. This improves the versatility and flexibility of the device, and also facilitates the individual replacement of damaged parts, reducing maintenance costs.

[0047] See Figure 1 and Figure 2 As shown, the aforementioned detachable structure can be achieved in the following way: The bracket 140 has two symmetrical open slots 142 below the angle steel 130. The bottom of the open slots 142 is connected to the support plate 120 by bolts 143, so that the bracket 140 is detachably fixed to the upper end of the support plate 120. The combination of bolts 143 and open slots 142 facilitates quick installation and disassembly of the bracket 140, while also ensuring the connection strength and stability between the bracket 140 and the support plate 120, thus ensuring the reliability of the overall structure of the support frame 100.

[0048] See Figure 1 and Figure 2 As shown, the support foot 200 is provided with a vertically extending stud 210, and the support plate 120 of the support frame 100 is provided with a threaded hole adapted to the stud 210. The stud 210 passes through the threaded hole and is locked to the support frame 100 by a nut 220. When it is necessary to adjust the height of the support frame 100, first loosen the nut 220, adjust to the predetermined height, and then fix the stud 210 relative to the support plate 120 by the nut 220. Through this threaded connection method, the height of the support foot 200 can be easily adjusted, thereby achieving precise adjustment of the height of the support frame 100.

[0049] See Figure 1 and Figure 2 As shown, the support foot 200 has a base 230 at the bottom end of the stud 210. The base 230 is used to increase the support area. Increasing the support area can improve the contact stability between the support foot 200 and the ground and enhance the load-bearing capacity of the support device.

[0050] See Figure 1 and Figure 2 As shown, the aforementioned buffer pad 300 can be a rubber pad, which is fitted into the V-groove 110, and the shape of its upper end face is the same as that of the V-groove 110. The rubber pad has good elastic deformation capacity and buffering performance, effectively absorbing the impact force generated when the lead screw is placed, reducing rigid collisions between the lead screw and the V-groove 110, and protecting the lead screw surface from damage. At the same time, the close fit between the rubber pad and the V-groove 110 increases the friction between the lead screw and the V-groove 110, preventing the lead screw from slipping during installation, and further improving the stability and accuracy of the lead screw installation.

[0051] The installation process of the lead screw installation auxiliary support device in this embodiment is as follows: First, the rubber buffer pad is attached to the V-groove 110 of the angle steel 130. Since the upper end face of the rubber pad is the same as the V-groove 110, it can fit tightly, preparing for subsequent lead screw support. Next, the bracket 140 with the angle steel 130 is assembled with the support plate 120 through the open groove 142. The bracket 140 is placed on the support plate 120, so that the bottom of the open groove 142 corresponds to the support plate 120. Then, bolts 143 are passed through the holes at the bottom of the open groove 142 and on the support plate 120, and tightened with nuts 220 to complete the detachable fixed connection between the bracket 140 and the support plate 120. At this time, the angle steel 130 is also firmly installed on the support frame 100. Finally, pass the end of the support foot 200 with the stud 210 through the screw hole on the support frame 100, and fix the support foot 200 to the support frame 100 by rotating the nut 220, but do not tighten it yet, so that the height can be adjusted later.

[0052] The supporting process of the lead screw installation auxiliary support device in this embodiment is as follows: The lead screw is slowly inserted into the V-groove 110 from the opening 112 upwards. Under the action of gravity, the lead screw falls into the V-groove 110. Since the two groove walls 111 of the V-groove 110 are symmetrical and inclined to the horizontal plane, they will form an initial wrapping support for the lead screw. At this time, the lead screw contacts the rubber buffer pad covering the surface of the groove wall 111. The rubber buffer pad undergoes elastic deformation, tightly adhering to the surface of the lead screw, further increasing the stability of the support and the contact area. At the same time, the elasticity of the buffer pad can also absorb the impact force generated when the lead screw is placed, protecting the surface of the lead screw from damage. Subsequently, the height of the support foot 200 is adjusted. By rotating the nut 220 on the support foot 200, the stud 210 moves up and down in the screw hole, thereby changing the relative position of the support foot 200 and the support frame 100, and thus adjusting the height of the support frame 100. With at least three support feet 200, the support frame 100 can be kept horizontal by adjusting the height of each support foot 200. This ensures that the lead screw is stably supported in the V-groove 110, preventing uneven force distribution or slippage of the lead screw due to tilting of the support frame 100. The base 230 at the bottom of the support foot 200 increases the support area, enhances the contact stability between the support device and the ground, improves the load-bearing capacity of the entire support system, and ensures that the lead screw remains stably positioned on the support frame 100 during installation.

[0053] The working principle of the lead screw installation auxiliary support device in this embodiment to assist in the correction of the lead screw is as follows: When the lead screw is placed in the V-groove 110, the geometry of the V-groove 110 will provide initial positioning for the lead screw. Since the two groove walls 111 of the V-groove 110 are symmetrical and inclined, the lead screw will naturally slide down along the groove walls 111 under the action of gravity until its axis aligns with the axis of symmetry of the V-groove 110. If there is a slight offset or tilt when the lead screw is placed, the groove walls 111 will restrict the degree of freedom of the lead screw, guiding it to gradually adjust to the correct position, achieving initial correction of the lead screw, and enabling the lead screw to reach a relatively accurate position in the horizontal direction. After the lead screw is initially positioned, if a deviation is found in the vertical direction between the lead screw and other related equipment or components, it can be corrected by further adjusting the height of the support feet 200. For example, if the lead screw needs to be raised, the nut 220 on the relevant support foot 200 can be rotated simultaneously to move the stud 210 upward, thereby raising the height of the support frame 100; if the lead screw needs to be lowered, the nut 220 can be rotated in the opposite direction to move the stud 210 downward. By precisely adjusting the height of the support foot 200, the installation height and angle of the lead screw can be changed, allowing it to precisely match with other equipment or components to meet installation accuracy requirements. During the adjustment process, due to the stable support of the V-groove 110 and the buffer pad 300, the lead screw can maintain a relatively stable position during the adjustment process, facilitating precise correction.
