Description

Technical Field

[0001] This utility model relates to the field of support base technology, and in particular to a device that combines a lead screw support base and a motor base into a whole. Background Technology

[0002] Currently, most lead screw support seats and motor mounting seats are separate. This split design requires the mounting surfaces of the support seat and motor seat to be leveled and aligned separately, making it difficult to guarantee assembly accuracy. The structure is also larger and occupies more space; the separate, independent base increases the size of the equipment, which is not conducive to compact design. Installation is more difficult, requiring highly skilled installers, and the adjustment time is longer, increasing assembly time and maintenance costs. After installation, the coaxiality between the lead screw shaft end and the motor shaft at the flange end of the lead screw seat is relatively large, which can easily generate vibration and noise during operation, affecting positioning accuracy.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Reference Figures 1 to 6This utility model provides a device that integrates a lead screw support seat and a motor seat into a single unit. The device includes a motor seat, with a lead screw support seat 5 located at the upper right end of the motor seat. The motor seat and the lead screw support seat 5 are integrally formed. A bearing mounting hole extending into the lead screw support seat 5 is located on the left end face of the lead screw support seat 5. A motor mounting flange hole 9, coaxial with the bearing mounting hole, is located at the left end of the bearing mounting hole. A bearing cap 6 is located at the left end of the bearing mounting hole. A first through hole penetrating the bearing cap 6 is located in the middle of the bearing cap 6. A second through hole communicating with the bearing mounting hole is located on the right end face of the lead screw support seat 5. A first isolation ring 14 and a first oil seal 10, coaxial with the bearing 11, are located on the left side of the bearing 11. The first isolation ring 14 is... In the middle of the first oil seal 10, both the first isolation ring 14 and the first oil seal 10 are located in the first through hole. An integrated square nut 15 is provided on the left side of the first isolation ring 14. A second isolation ring 13 and a second oil seal 12, coaxial with the bearing 11, are provided on the right side of the bearing 11. The second isolation ring 13 is located in the middle of the second oil seal 12. Both the second isolation ring 13 and the second oil seal 12 are located in the second through hole. The four corners of the screw support 5 are provided with first bolt mounting holes. The four corners of the bearing cap 6 are provided with second bolt mounting holes that mate with the first bolt mounting holes. The second bolt mounting holes are provided with internal threads. Each of the first bolt mounting holes is provided with a connecting bolt 4. The tail end of the connecting bolt 4 is connected to the internal thread.

[0022] In this technical solution, the lead screw support 5 is integrated with the motor base as a single unit. The bearing mounting holes and motor mounting flange holes 9, as well as the bearing mounting surface and motor flange mounting surface, are all machined in a single setup on a specialized fixture, ensuring that the coaxiality of the bearing mounting holes and motor mounting flange holes is within 0.02 mm, and the parallelism of the bearing mounting surface 11 and the motor flange mounting surface is within 0.02 mm. After the bearing cap 6 is tightened with internal hexagonal head bolts, the bearing 11 achieves a pre-tightening effect, guaranteeing its rigidity and precision. This integrated design reduces assembly errors and the generation and transmission of vibration during operation. During installation, there is no need to adjust the coaxiality and parallelism of the bearing mounting holes and motor mounting flange holes, significantly reducing installation time and saving 50% of labor. The improved coaxiality reduces the deviation between the lead screw shaft and the motor shaft, making coupling installation smoother, reducing radial force caused by excessive coupling eccentricity, and extending the service life of the coupling and bearings.

[0023] Motor mount: Made of QT450 cast blank, it is machined on a high-precision machining center and CNC machine using special fixtures and cutting tools, and is the main component of the entire assembly.

[0024] Integrated square nut 15: Used in conjunction with the thread on the end of the lead screw to lock the inner ring of the bearing.

[0025] Bearing cap 6: Used to press the outer ring of the bearing to achieve the purpose of pre-tightening the bearing.

[0026] Bearing 11: Standard part, used in conjunction with the lead screw end.

[0027] First oil seal 10 and second oil seal 12: standard parts, used in conjunction with screw support seat 5 and bearing cover 6, and used in conjunction with first isolation ring 14 and second isolation ring 13 to prevent dust.

[0028] First isolation ring 14 and second isolation ring 13: installed at both ends of bearing 11, used in conjunction with first oil seal 10 and second oil seal 12 to prevent dust.

[0029] For example, in some embodiments, the motor mount includes a base plate 3 and a vertical plate 8 located at the left end of the base plate 3. The motor mounting flange hole 9 is located on the vertical plate 8. The left end of the upper surface of the base plate 3 is provided with a motor mounting groove 2 for mounting the motor, and the lower end of the motor mounting groove 2 extends through to the lower surface of the base plate 3. This facilitates motor installation and also enables the integrated machining of the lead screw support 5.

[0030] For example, in some embodiments, the base plate 3 has third bolt mounting holes 1 at both its front and rear ends, and the vertical plate has fourth bolt mounting holes 7 at both its front and rear ends. This facilitates the installation of the motor mount.

[0031] For example, in some embodiments, the integrated square nut 15 has at least one set screw hole on its outer surface, the set screw hole extending into the interior of the integrated square nut 15, and a set screw 16 is provided in the set screw hole. This facilitates a more secure connection with the lead screw end.

[0032] For example, in some embodiments, the connecting bolt 4 is a hexagon socket head cap bolt. The hexagon socket head cap bolt is a standard part, which is connected to the bearing cap 6 to lock the bearing cap 6 to achieve the purpose of pre-tightening the bearing 11.

[0033] In summary, the lead screw support and motor base of this utility model are integrated into a single unit. The bearing mounting holes and motor mounting flange holes, as well as the bearing mounting surface and motor flange mounting surface, are all machined in a single setup on a specialized fixture. This ensures that the coaxiality of the bearing mounting holes and motor mounting flange holes meets the usage requirements. This integrated design reduces assembly errors and minimizes the generation and transmission of vibration during operation. During installation, there is no need to adjust the coaxiality and parallelism of the bearing mounting holes and motor mounting flange holes, significantly reducing installation time and saving 50% of labor. The improved coaxiality reduces the deviation between the lead screw shaft and the motor shaft, making coupling installation smoother, reducing radial force caused by excessive coupling eccentricity, and extending the service life of the coupling and bearings.
