DETAILED DESCRIPTION
[0025] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.
[0026] Referring to Figure 1 and Figure 2 , the installation support 1 provides a stable installation base when the quick change device of the gland of the twist head machine is working, and at least three groups of locking heads uniformly distributed on the bottom thereof act synchronously, the lock tongue 2 of the locking head is precisely inserted into the clamping groove 4 extended outside the gland 3, and the multi-point positioning of the gland 3 is quickly completed. This working mode does not need to rely on additional tools, is convenient to operate and efficient in positioning, and the uniform distribution of at least three groups of locking heads can balance the stress of the gland 3, cooperate with the precise fitting of the lock tongue 2 and the clamping groove 4, effectively avoid the loosening and displacement of the gland 3 during the operation of the twist head machine, greatly shorten the replacement time of the gland 3, and guarantee the positioning accuracy of the gland 3 after installation, thereby improving the workpiece machining quality and production efficiency.
[0027] Referring to Figure 2 , the installation plate 5 fixedly connected with the lower end of the mounting support 1 provides stable support for the overall structure, and the fixed mounting seat 6 with a guide groove between the installation plate 5 forms a gap suitable for placing the lock tongue 2. The guide groove of the mounting seat 6 can provide precise guidance for the extension and contraction of the lock tongue 2, and ensure that the lock tongue 2 always moves smoothly along the preset track. This structure design not only realizes the reliable installation and flexible movement of the lock tongue 2, but also guarantees the stability of the overall structure of the locking head through the fixed connection of the installation plate 5 and the mounting seat 6, avoids the deviation or jamming of the lock tongue 2 during movement, lays a solid foundation for subsequent precise butt joint of the gland 3 and rapid positioning, simplifies the assembly process of the locking head, and improves the structural reliability.
[0028] Referring to Figure 3 and Figure 4When the lock tongue 2 is in operation, the tail end limiting groove 7 cooperates with the front end inwardly bent limiting plate 8, and the front end of the pull rod 9 is connected with the double limiting structure of the inner recess limiting ring 10 and the end protrusion, that is, the limiting ring 10 is clamped into the limiting plate 8, and the end protrusion is embedded in the limiting groove 7. The double clamping mode ensures that the lock tongue 2 and the pull rod 9 are synchronously linked, and the pull rod 9 can accurately drive the lock tongue 2 to stretch and retract, effectively avoiding the relative displacement or loosening between the two, ensuring the consistency and reliability of the locking and unlocking actions. At the same time, the structure is simple and compact, and stable connection can be achieved without complex connecting parts, which reduces the assembly difficulty and improves the precision of component cooperation, providing stable power transmission protection for the quick positioning and replacement of the gland 3.
[0029] Referring to Figure 4 and Figure 5 When the pull rod 9 is in operation, the threaded section at the tail end of the pull rod 9 provides a mounting base for the tail plate 11. After the tail plate 11 is sleeved on the threaded section, it is stably fixed with the pull rod 9 through the nuts on both sides. The clamping plate 12 at the lower end of the tail plate 11 beyond the lower edge of the mounting seat 6 becomes a key unlocking component. When the gland 3 needs to be unlocked, the tail plate 11 is pulled and rotated backward, and the clamping plate 12 is accurately limited on the side wall at the tail end of the mounting seat 6 to form a limit, thereby driving the pull rod 9 to move synchronously to link the lock tongue 2 to separate from the clamping groove 4 of the gland 3. This structure can complete the unlocking operation without the help of additional tools, making the replacement process of the gland 3 more convenient and efficient, and ensuring the stable connection and accurate action of the pull rod 9 and the tail plate 11 through the double protection of nut fixation and clamping plate 12 limiting, avoiding loosening or displacement during operation, and providing strong support for the reliable operation of the device.
[0030] Referring to Figure 3 The spring 13 sleeved on the pull rod 9 between the tail end of the lock tongue 2 and the inner end of the guide groove of the mounting seat 6 is always in a compressed state and generates a continuous elastic force in the locked state of the device, tightly pushing the lock tongue 2 to keep it closely fitted with the clamping groove 4 of the gland 3, effectively avoiding the loosening and displacement of the lock tongue 2 caused by the vibration of the head twisting machine during operation. When unlocking, the spring 13 is further compressed as the lock tongue 2 is retreated with the pull rod 9, and releases the elastic potential energy after the tail plate 11 is loosened, pushing the lock tongue 2 to automatically reset to the initial positioning position along the guide groove of the mounting seat 6. This design not only simplifies the reset operation after replacing the gland 3 without manual adjustment of the lock tongue 2 position, but also ensures the stability and positioning accuracy of the locking through the continuous elastic pressure, buffers the impact force when the lock tongue 2 and the pull rod 9 are linked, reduces the wear of components, and prolongs the service life of the device.
[0031] Referring to Figure 4When the tail plate 11 works, the clamping groove 14 on the inner side thereof is matched with the flat sides of the inner side nut, the nut can be accurately clamped into the clamping groove 14 after being fixed and installed, effective limiting is formed, the nut can be firmly limited from rotating during the locking or unlocking process of the device, nut loosening and displacement caused by vibration of the head twisting machine or stress of the tail plate 11 during operation is avoided, the connection stability of the tail plate 11 and the pull rod 9 is ensured, the action of the tail plate 11 driving the pull rod 9 to link the locking tongue 2 is ensured to be accurate and reliable, meanwhile, the installation and positioning process of the nut is simplified, the convenience of component assembly and the reliability of the overall structure are improved, and protection is provided for stable operation of the device.
[0032] The working principle of the present application is as follows: When the head twisting machine gland quick changing device works, the installation support 1 provides stable support as the core installation base, the installation plate 5 fixedly connected to the lower end thereof and the installation seat 6 with a guide groove below form an installation space, the locking tongue 2 is placed in the gap therebetween and is guided and limited by the guide groove; the tail end of the locking tongue 2 is double-clamped with the limiting ring 10 at the front end of the pull rod 9 and the limiting plate 8 through the limiting groove 7, thereby realizing synchronous linkage of the two; the tail plate 11 sleeved with the threaded section at the tail end of the pull rod 9 is fixed by the two nuts, and the nuts are clamped into the clamping grooves 14 on the inner side of the tail plate 11 to prevent loosening; the spring 13 between the tail end of the locking tongue 2 and the inner end of the guide groove of the installation seat 6 always maintains an elastic compression state. When the gland 3 is installed, the spring 13 pushes the locking tongue 2 to be accurately inserted into the clamping groove 4 extended outside the gland 3, and at least three groups of locking heads are uniformly distributed to complete multi-point positioning simultaneously; when unlocking and replacing, the tail plate 11 is pulled backward and rotated, the clamping plate 12 at the lower end thereof is tightly pressed against the side wall of the tail end of the installation seat 6 to realize limiting, at the same time, the pull rod 9 is linked to drive the locking tongue 2 to be separated from the clamping groove 4, after replacement is completed, the tail plate 11 is loosened, the spring 13 pushes the locking tongue 2 to be automatically returned, and the next installation and positioning is waited.
