Description

Technical Field

[0001] The utility model relates to the technical field of centering tooling, in particular to a centering tooling for wire lapping processing. Background Art

[0002] Since the steel structure scaffolding materials are processed in batches, with thousands of them being processed simultaneously each time, conflicts with ship repair parts are inevitable when processing the scaffolding.

[0003] The spanning material is Φ30mm round steel. The smallest inner hole of the new machine tool after replacement is Φ85mm. When the spanning material is directly clamped and turned, the vibration generated by the turning tool cutting the round steel will cause the spanning material to swing at the end of the machine tool inner hole. The spanning material will directly hit the inner wall of the machine tool inner hole, which will not only damage the machine tool, but also pose a certain risk, making the tool head easily broken.

[0016] In a possible implementation, the telescopic rod assembly includes a fixed shaft and a telescopic shaft, the fixed shaft is provided with a guide groove, and a spring is installed inside the guide groove, one end of the telescopic shaft is embedded in the guide groove and is slidably connected to the guide groove, one end of the spring is fixed to the inner wall of the guide groove, and the other end of the spring is fixed to the telescopic shaft.

Both sides of the locking block are provided with arc plates, which play a guiding role. When one end of the mounting material is extended into the inner hole, the mounting material first contacts with the arc plate.

When installing the mounting material 15, one end of the mounting material 15 passes through the Morse cone assembly 6. The Morse cone assembly 6 is used to limit and fix one end of the mounting material 15 in the inner hole 4 of the machine tool to prevent the vibration generated when the turning tool cuts the round steel from causing the vibration of the tail end of the mounting material 15, effectively avoiding the swinging phenomenon of the mounting material 15 during the processing, and avoiding the mounting material 15 directly hitting the inner wall of the inner hole 4 of the machine tool, so as to improve the safety during the processing, avoid damaging the machine tool body 1, eliminate the risk of collision, improve the safety of the machine tool body 1 during the processing of the mounting material 15, and eliminate safety hazards.

[0051] Embodiment 2

[0052] Based on the first embodiment, this embodiment introduces a specific structure of the Hough locking sleeve 8 in the centering tool for wire lapping processing, such as Figure 8 , Fig. 9 and Fig.10 As shown, the Huff locking sleeve 8 is fixedly arranged at the tail end of the Huff positioning sleeve 7, the Huff locking sleeve 8 and the Huff positioning sleeve 7 are divided into upper and lower parts, the Huff locking sleeve 8 and the Huff positioning sleeve 7 are tightly attached to the inner hole 4, the Huff positioning assembly 5 is composed of the Huff positioning sleeve 7 and the Huff locking sleeve 8, one end of the mounting material 15 passes through the Morse taper assembly 6, the mounting material 15 is limited and fixed at one end of the inner hole 4 of the machine tool by the Morse taper assembly 6, the mounting material 15 is limited and fixed by the Huff positioning sleeve 7, and the mounting material 15 is elastically locked and fixed by the Huff locking sleeve 8.

[0053] In some examples, a plurality of telescopic rod assemblies 18 are provided on the inner side surface of the Huff locking sleeve 8, and the plurality of telescopic rod assemblies 18 are evenly spaced along the circumferential direction of the Huff locking sleeve 8. When the mounting material 15 is limited by the Huff locking sleeve 8, the mounting material 15 is evenly stressed, and a locking cavity is formed between the plurality of telescopic rod assemblies 18. The plurality of telescopic rod assemblies 18 can shrink accordingly according to the diameter of the mounting material 15. When the plurality of telescopic rod assemblies 18 shrink, the locking blocks 22 at one end thereof are driven to move synchronously, and the mounting material 15 passes through the locking cavity. The plurality of locking blocks 22 are tightly attached to the outer surface of the mounting material 15 to fix it. The Huff locking sleeve 8 and the Huff positioning sleeve 7 together constitute a double fixing structure, which improves the stability of the mounting material 15 during processing.

[0054] In some examples, the telescopic rod assembly 18 includes a fixed shaft 19 and a telescopic shaft 20, the fixed shaft 19 has a built-in guide groove, and a spring 21 is installed inside the guide groove, one end of the telescopic shaft 20 is embedded in the guide groove and slidably connected with the guide groove, and one end of the spring 21 is fixed to the inner wall of the guide groove, and the other end of the spring 21 is fixed to the telescopic shaft 20, the spring 21 will automatically contract when subjected to an external force, and automatically rebound by its own elastic force after the external force disappears, such as Figure 2 As shown, when one end of the mounting material 15 extends into the inner hole 4 and extends to the locking cavity of the Hough locking sleeve 8, the multiple sets of telescopic rod assemblies 18 drive the multiple sets of locking blocks 22 to move. Under the action of the elastic force of the spring 21, the multiple sets of locking blocks 22 are tightly attached to the outer surface of the mounting material 15 to fix one end of the mounting material 15. After the mounting material 15 is processed and taken out, the multiple sets of locking blocks 22 are reset to the initial state under the action of the rebound force of the spring 21.

[0055] Among them, one end of the mounting material 15 is fixed for the first time by the Hough positioning sleeve 7, and the other end of the mounting material 15 is fixed for the second time by the Hough locking sleeve 8. The double fixing method further prevents the vibration generated when the turning tool cuts the round steel from causing the vibration of the tail end of the mounting material 15, further effectively avoids the swinging phenomenon of the mounting material 15 during the processing, and further avoids the mounting material 15 directly hitting the inner wall of the inner hole 4 of the machine tool, thereby further improving the safety during the processing.

[0056] In some examples, a locking block 22 is welded and fixed at one end of the telescopic shaft 20, and an elastic anti-slip lining 23 is provided on the locking surface of the locking block 22. The elastic anti-slip lining 23 has certain elasticity and anti-slip properties, and the elastic anti-slip lining 23 is bonded and fixed to the locking block 22. Under the action of the elastic force of the spring 21, multiple groups of locking blocks 22 are tightly attached to the outer surface of the mounting material 15. The elastic anti-slip lining 23 on the locking surface of the locking block 22 is in close contact with the outer surface of the mounting material 15, which increases the contact friction between the locking block 22 and the mounting material 15, thereby improving the stability when fixing the mounting material 15. Arc plates 24 are provided on both sides of the locking block 22.

[0057] Among them, the arc plate 24 plays a guiding role. When one end of the mounting material 15 extends into the inner hole 4, the mounting material 15 first contacts the arc plate 24. When the mounting material 15 continues to extend, the arc plate 24 drives the locking block 22. The locking block 22 applies an extrusion force to the spring 21. The spring 21 is compressed and drives the telescopic shaft 20. The telescopic shaft 20 drives the locking block 22 to avoid, so that multiple groups of locking blocks 22 are tightly attached to the outer surface of the mounting material 15 under the action of the elastic force of the spring 21, thereby fixing the mounting material 15.

[0058] By adopting the above technical solution:

[0059] The Huff locking sleeve 8 and the Huff positioning sleeve 7 together constitute a double fixing structure. The Huff positioning sleeve 7 is used to limit and fix the saddle material 15, and the Huff locking sleeve 8 is used to elastically lock and fix the saddle material 15. The double fixing method further prevents the vibration generated when the turning tool cuts the round steel from causing the vibration of the tail end of the saddle material 15, further effectively prevents the saddle material 15 from swinging during the processing, and further prevents the saddle material 15 from directly hitting the inner wall of the inner hole 4 of the machine tool, further improving the safety during the processing;

[0060] The arc plate 24 plays a guiding role. When the bracket material 15 continues to extend, the arc plate 24 drives the locking block 22. The locking block 22 applies an extrusion force to the spring 21. The spring 21 is compressed and drives the telescopic shaft 20. The telescopic shaft 20 drives the locking block 22 to automatically avoid.

[0061] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
