DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0026] The embodiments of the present invention provide a lead screw base mounting plate. Exemplarily, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, it includes a lead screw mounting plate, and the lead screw mounting plate further includes a base plate 1. The base plate 1 has reinforcing ribs to increase structural rigidity. At both ends of the base plate 1, positioning blocks are respectively fixed. The positioning blocks include a first positioning block 2 and a second positioning block 3. Both the first positioning block 2 and the second positioning block 3 are cylindrical structures, and a set of adjusting bolts 4 are arranged in the cavities of both the first positioning block 2 and the second positioning block 3. A reinforcing frame 5 is installed on the top of the base plate 1, and a stress dispersion member 6 is arranged at the joint of the reinforcing frame 5 and the base plate 1.
[0027] Specifically, the first positioning block 2 and the second positioning block 3 are used to accurately position the lead screw seat and enhance local rigidity to prevent position deviation during installation. The adjusting bolts 4 arranged in their cavities are used to finely adjust the position of the lead screw seat to maintain the precise perpendicularity of the lead screw.
[0028] In addition, the reinforcing frame 5 is used to improve the overall stability and further support the base plate 1 to avoid deformation caused by concentrated load.
[0029] In addition, the stress dispersion member 6 is used to share the externally applied load and evenly distribute the load to the entire structure, thereby preventing deformation under high load caused by excessive stress on any single point.
[0030] A set of preset holes are provided at the four corners of the base plate 1, and a set of screws 7 are respectively installed corresponding to each set of preset holes. The base plate 1 is firmly connected to the equipment base through the screws 7. A plurality of support feet 8 are added on the base plate 1, and the support feet 8 are located in the key load-bearing area on the lower side of the base plate 1.
[0031] Specifically, the first positioning block 2 and the second positioning block 3 are made of modular integral castings and are fixed to the inner side of the groove on the surface of the base plate 1 through multiple groups of screw hole groups, forming a stable three-dimensional frame structure at the end of the base plate 1 to enhance the positioning accuracy and prevent sliding and displacement under load.
[0032] In addition, the setting of the support feet 8 reduces the deformation amount on the installation surface while improving the stability in the lifting plane direction.
[0033] A spiral groove and a guide rod 9 are arranged inside the adjusting bolt 4, and the guide rod 9 moves vertically along the positioning block. The reinforcing frame 5 is made of high-strength steel bending parts and surrounds the positioning block, and is firmly connected to the frame of the base plate 1 with solder joints.
[0034] Specifically, the setting of the adjusting bolt 4 enables the operator to perform fine adjustment during the assembly stage or during operation to ensure that the lead screw is straight and not deflected.
[0035] In addition, for the reinforcement frame 5, this design provides rigid support for the overall structure during the movement of the lead screw, reduces the vibration frequency, and avoids the sinking and deformation of the center of the substrate 1 caused by pressure.
[0036] The stress dispersion member 6 is internally embedded with a spherical spring washer 10, and the spherical spring washer 10 can transfer loads in different directions. A support rib plate 11 is arranged below the middle area between the two positioning blocks, and the support rib plate 11 is in a cross shape.
[0037] Specifically, the spherical spring washer 10 embedded in the stress dispersion member 6 avoids damage caused by stress concentration and the resulting phenomenon of buckling instability in the middle of the plate.
[0038] In addition, as an important part of the substrate 1, the support rib plate 11 helps the base disperse the transverse shear force when transmitting the vertical load, enhances the structural strength, and avoids local deflection.
[0039] The edge part of the surface of the substrate 1 intersecting with the positioning block is processed with a transition arc, and the inner cavity of the reinforcement frame 5 is filled with foam plastic 12.
[0040] Specifically, the edge part of the substrate 1 intersecting with the positioning block is processed with a transition arc, which ensures that the joint surface between components has sufficient contact area when welding the reinforcement frame 5, and reduces the warping of the plate caused by the pulling stress due to uneven edges.
[0041] In addition, the foam plastic 12 serves as an auxiliary support material to reduce its own weight under the requirement of self-weight, prevent the plate from vibrating in the working environment of rapid feed of the lead screw, and buffer the instantaneous transmission of force caused by external impact.
[0042] Working principle
[0043] During the actual operation process, when this device is used, the substrate 1 first serves as the load-bearing and installation foundation of the entire lead screw base mounting plate, and reinforcing ribs are provided thereon to enhance the rigidity and strength of the entire structure. The two positioning blocks are respectively located at both ends of the substrate 1 and are firmly fixed in this position; these two positioning blocks can not only provide precise geometric positioning for the lead screw base but also improve the local strength and prevent displacement that may occur during the installation process. One or both of the positioning blocks are also equipped with adjusting bolts 4, and after assembly, this device can be used to make minor adjustments to the position of the lead screw so that the lead screw can accurately maintain the required perpendicularity.
[0044] The reinforcement frame 5 is installed on the substrate 1 and is designed to form an enclosing shape around the lead screw base to improve the overall stability of the system. At the same time, it also strengthens the support for the substrate 1 itself to slow down the deformation caused by the local bearing of a large load. Stress dispersion components 6 are also integrated into the structure, and these components are placed at the positions that are most stressed by the machine operation or at the connection areas of the various parts of the reinforcement frame 5. Such a setting can make the force applied to the entire lead screw base be averaged and dispersed throughout the device, effectively preventing the occurrence of structural instability or permanent deformation due to excessive stress on a specific area. The design of all components fully takes into account the problems that may be faced in the machining process and the subsequent application environment. Through the above design, the working performance of the entire installation structure can be significantly improved, and long-term operation stability can be ensured.
[0045] All the technical features in this embodiment can be freely combined according to actual needs.
[0046] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
