Technical Field

[0001] This utility model relates to the field of modular quick-release spindle box technology, specifically a modular quick-release structure for a turning and milling machining center spindle box. Background Technology

[0002] The modular quick-release structure of the spindle box in a turning and milling machining center is a mechanical design that allows for rapid replacement of spindle box components, aiming to improve the versatility and maintenance efficiency of the equipment.

[0003] The existing modular quick-release structure of the spindle box still has two major technical defects in practical applications: On the one hand, due to the insufficient matching accuracy of common positioning components, the positioning effect during assembly is poor, which seriously affects the dynamic stability of the spindle box after installation and is prone to micron-level displacement deviation under high-speed machining conditions; on the other hand, traditional sealing structures (such as single rubber sealing rings) are prone to wear of the sealing surface under frequent disassembly and assembly conditions, which leads to the risk of leakage in the lubrication system, not only polluting the machining environment, but also potentially causing abnormal wear of the spindle bearing due to insufficient lubrication. Utility Model Content

This invention employs a precision-fitting structure of positioning pins, positioning grooves, sealing grooves, and sealing pins to ensure assembly positioning accuracy. Simultaneously, it achieves adaptive sealing compensation through a multi-layer sealing system composed of rubber sealing seats, pin grooves, locking pins, and rubber sealing covers. This solves the problem of insufficient positioning accuracy in traditional quick-release structures and effectively prevents lubricant leakage. While ensuring convenient assembly and disassembly, it significantly improves the stability and sealing reliability of the spindle box assembly and sealing cover; thus addressing the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A modular quick-release structure for a milling and turning machining center spindle box includes a spindle box body 1, a sealing cover 2, a positioning assembly, and a fixing assembly. The spindle box body 1, as the core functional component of the milling and turning machining center, primarily plays a crucial role in supporting the spindle, transmitting power, and ensuring machining accuracy. The sealing cover 2 is mounted on the top of the spindle box body 1, and a positioning assembly for quick positioning is provided between the spindle box body 1 and the sealing cover 2. The positioning assembly includes positioning pins 4, positioning grooves 401, sealing grooves 5, and sealing pins 501. The positioning pins 4 are fixedly installed around the bottom of the sealing cover 2, and are engaged with corresponding positioning grooves 401 on the top of the spindle box body 1. Several sets of sealing pins 501 are fixedly installed on the front and back ends of the bottom of the sealing cover 2, and are engaged with corresponding sealing grooves 5 on the top of the spindle box body 1. The sealing grooves 5 and sealing pins 501 are compatible.

[0027] Furthermore, by removing the sealing cover 2, the positioning post 4 and sealing post 501 at its bottom are respectively locked into the corresponding positioning groove 401 and sealing groove 5 on the spindle housing 1, so as to achieve rapid positioning; thereby improving the positioning and assembly stability of the spindle housing 1 and the sealing cover 2.

[0028] This invention effectively solves the problem of insufficient positioning accuracy in existing technologies by setting up a positioning post 4 and a positioning groove 401 between the spindle housing 1 and the sealing cover 2, in conjunction with the synergistic effect of the sealing groove 5 and the sealing post 501. This structure achieves alignment and fixation of the spindle housing 1 and the sealing cover 2 during assembly, significantly improving the positioning and assembly stability of the spindle housing 1 and the sealing cover 2. At the same time, this design of the mating structure ensures both ease of assembly and disassembly, and guarantees the structural rigidity after assembly, providing an important guarantee for the reliable operation of the modular quick-release spindle housing.

[0029] The spindle housing 1 and the sealing cover 2 are provided with fixing components at both ends of the front and back sides for easy installation and fixation. The fixing components include a first bonding plate 3, a second bonding plate 301, a fixing bolt 302, and a retainer 303. The first bonding plate 3 is fixedly installed at the lower ends of the front and back sides of the sealing cover 2, and the second bonding plate 301 is fixedly installed at the upper ends of the front and back sides of the spindle housing 1, and the first bonding plate 3 and the second bonding plate 301 are sealed together. The retainer 303 is snapped onto the outer side of the first bonding plate 3 and the second bonding plate 301, and the top ends of the retainer 303 are provided with fixing bolts 302. The fixing bolts 302 pass through the retainer 303, the first bonding plate 3, and the second bonding plate 301 in sequence to achieve the snapping and fixing of the spindle housing 1 and the sealing cover 2.

[0030] This utility model achieves a sealed fit between the first bonding plate 3 and the second bonding plate 301. Then, the retainer 303 is removed and secured to the outside of the first bonding plate 3 and the second bonding plate 301. Next, the fixing bolt 302 is removed and passed through the retainer 303, the first bonding plate 3, and the second bonding plate 301 in sequence, thereby facilitating threaded fixation and improving the stability of the fixation.

[0031] A sealing assembly for easy sealing is provided at the upper part of the spindle housing 1 and the bottom of the sealing cover 2. The sealing assembly includes a rubber sealing seat 6, a groove 601, a retaining post 602, and a rubber sealing cover 603. The rubber sealing seat 6 is fixedly installed on the upper part of the inner wall of the spindle housing 1. Several sets of grooves 601 are opened at the front and back ends of the top surface of the rubber sealing seat 6. The rubber sealing cover 603 is fixedly installed at the bottom of the sealing cover 2. Several sets of retaining posts 602 are installed at the front and back ends of the bottom of the rubber sealing cover 603. The retaining posts 602 are engaged with the inside of the grooves 601. The rubber sealing cover 603 fits against the inner wall of the spindle housing 1, and the retaining posts 602 are adapted to the grooves 601.

[0032] This utility model improves the sealing effect by aligning the rubber sealing cover 603 at the bottom of the sealing cover 2 with the opening inside the spindle housing 1 during installation. This allows the bottom of the rubber sealing cover 603 to fit tightly against the rubber sealing seat 6. At the same time, the retaining post 602 at the bottom of the rubber sealing cover 603 is engaged in the corresponding groove 601 at the top of the rubber sealing seat 6.

[0033] This utility model employs a structure consisting of a rubber sealing seat 6, a groove 601, a retaining post 602, and a rubber sealing cover 603, which work together to facilitate positioning and sealing during the assembly of the spindle housing 1 and the sealing cover 2. Simultaneously, the tightly fitted rubber sealing seat 6 and the rubber sealing cover 603 form a multi-layer sealing interface, achieving a multi-layer sealing effect. Furthermore, the elastic characteristics of the rubber sealing cover 603 and the rubber sealing seat 6 enable adaptive sealing compensation. This structural design not only significantly improves the sealing reliability during the assembly of the spindle housing 1 and the sealing cover 2 but also maintains a stable sealing pressure under frequent disassembly and assembly conditions, effectively preventing lubricant leakage and reducing pollution of the processing environment.

[0034] The sealing cover 2 has grooves 201 on both sides for hooking with hands, making it easy to remove the sealing cover 2 from the spindle housing 1; the top center of the sealing cover 2 is hollow, which increases the internal space of the spindle housing 1.

[0035] In summary, this utility model employs a precision-fitting structure of positioning post 4, positioning groove 401, sealing groove 5, and sealing post 501 to ensure assembly positioning accuracy. Simultaneously, a multi-layer sealing system composed of rubber sealing seat 6, post groove 601, locking post 602, and rubber sealing cover 603 achieves adaptive sealing compensation. This dual technical solution not only solves the shortcomings of insufficient positioning accuracy in traditional quick-release structures but also effectively prevents lubricant leakage. While ensuring ease of assembly and disassembly, it significantly improves the stability and sealing reliability of the spindle housing 1 and sealing cover 2 assembly, providing comprehensive protection for the long-term stable operation of the modular quick-release spindle housing 1.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
