Description

Technical Field

[0001] This utility model relates to the field of sinking main boom processing technology, specifically to a precision machining tooling for sinking main booms. Background Technology

[0002] The settling arm is one of the fundamental components of a spinning machine, playing a crucial role in the overall structure. Its machining accuracy and surface quality significantly impact the stable operation of the spinning machine and the yarn formation effect. Currently, after the initial forming process, subsequent processing steps such as deburring and polishing of the settling arm primarily rely on manual operation. Furthermore, during these manual processes, the settling arm is generally fixed in place manually. Specifically, the operator needs to firmly grasp the settling arm with one hand, securing it to the worktable, while using the other hand to apply the appropriate processing tools.

[0003] Traditional manual fixing methods suffer from low positioning accuracy and unstable clamping force, which can easily lead to part displacement or loosening during processing, thus affecting processing accuracy and surface quality. Furthermore, manual fixing methods are difficult to integrate seamlessly with automated processing equipment, severely limiting the automation development of the sinking arm processing procedure.

[0004] In view of the above problems, it is particularly necessary to develop a precision machining tool specifically for the sinking main boom. Utility Model Content

[0032] 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.

[0033] This utility model provides a precision machining fixture for the main boom of a sinking structure, which is used to solve the problem of how to improve the clamping stability of the main boom 5.

[0034] See Figure 1 and Figure 2 As shown, Figure 1 This is a perspective view of the finishing fixture used for lowering the main boom in the embodiment. Figure 2 This is a cross-sectional view of the finishing fixture used for the settlement boom in the embodiment. The finishing fixture for the settlement boom includes a flange connecting block 1, a support 2, a pressure cap 3, and a screw rod 4.

[0035] The main sinking arm 5 has a slot 51, and the bottom of the slot 51 has a perforation 52.

[0036] Flange connection block 1 can be used to connect external machine tools or worktables.

[0037] The support 2 is fixed to the top of the flange connecting block 1 by means of screwing or welding, and the support 2 includes a limiting part 21. The limiting part 21 has a threaded hole 211, which is used to be inserted and adapted to the slot 51, and to limit the sinking main arm 5, so that the through hole 52 and the threaded hole 211 are positioned opposite each other and connected.

[0038] The pressure cap 3 is attached to the through hole 52 on the outside of the main settling arm 5. The pressure cap 3 has a connecting hole 31 that is opposite to and communicates with the threaded hole 211.

[0039] One end of the screw 4 is threaded into the threaded hole 211, and the other end passes through the through hole 52 and the connecting hole 31 in sequence, and abuts against the pressure cap 3. The screw 4 is used to drive the pressure cap 3 and the support 2 to move closer to each other, thereby pressing the main sinking arm 5 onto the support 2.

[0040] When using the above technical solution for the precision machining of the main settling arm, firstly, place the main settling arm 5 to be clamped and machined on the limiting part 21, so that the limiting part 21 is inserted into the slot 51, and the through hole 52 and the threaded hole 211 are aligned and connected; then, cover the pressure cap 3 on the through hole 52 on the outside of the main settling arm 5, so that the connecting hole 31 and the threaded hole 211 are aligned and connected; finally, pass one end of the screw 4 through the connecting hole 31 and the through hole 52, and then continuously screw it into the threaded hole 211, so as to drive the pressure cap 3 and the support 2 to move closer to each other until the main settling arm 5 is pressed and fixed on the support 2. As can be seen, this utility model, through the cooperation of the support 2, the pressure cap 3, and the screw 4, can firmly and stably clamp and fix the settlement main arm 5 to be processed, and apply a uniform and stable clamping force to the settlement main arm 5, effectively preventing the settlement main arm 5 from shaking and displacing during the processing, replacing manual fixing, thereby greatly improving the clamping stability of the settlement main arm 5 and ensuring the smooth progress of the processing; in addition, this utility model also has good compatibility, and can be externally connected to automated processing equipment through the flange connecting block 1, which is conducive to the automation development of the settlement main arm 5 processing process.

[0041] The aforementioned screw component 4 can use existing screws, bolts, and other threaded fasteners.

[0042] See Figure 1 and Figure 2 As shown, in the first embodiment of the limiting part 21, the limiting part 21 is prismatic in shape and has the same size and shape as the slot 51. The limiting part 21 contacts the bottom surface of the slot 51. In this way, the support 2, through the limiting part 21, contacts the surface of the sinking main arm 5, which not only stably supports the sinking main arm 5, but also improves the uniformity and stability of the clamping force of the tooling, thereby further improving the clamping stability of the tooling for the sinking main arm 5.

[0043] See Figure 3 As shown, Figure 3 This is a cross-sectional view of the gland, screw, and support in the second embodiment. In the second embodiment of the limiting part 21, the limiting part 21 is frustum-shaped and wedge-shaped with the slot 51. Thus, in order to accommodate slots 51 of different types of sinking main arms 5 of the same model, the size of the limiting part 21 provided in the previous embodiment is designed to be slightly smaller than the size of the slot 51 to improve the versatility of the tooling. However, this would result in the limiting part 21 not being able to effectively position the sinking main arm 5, and the sinking main arm 5 may experience slight displacement or wobbling during processing. In contrast, the limiting part 21 provided in this embodiment, wedge-shaped with the slot 51, can accurately position the sinking main arm 5 and quickly align the threaded hole 211 and the through hole 52, effectively preventing displacement or wobbling of the sinking main arm 5 during processing, thereby further improving the processing accuracy of the sinking main arm 5.

[0044] See Figure 1 and Figure 2 As shown, based on any of the above embodiments, the finishing fixture for lowering the main boom also includes a heightening seat 6. The flange connecting block 1 has a first flange hole 11. The top end of the heightening seat 6 is detachably connected to the first flange hole 11 of the flange connecting block 1 via a threaded connection. The bottom end of the heightening seat 6 has a second flange hole 61 for detachable connection to an external machine tool or worktable. Thus, in most cases, this finishing fixture for lowering the main boom is installed on an external machine tool or worktable via the first flange hole 11 of the flange connecting block 1. However, when it is necessary to raise the clamping position of the lowering main boom 5 for processing equipment operation or manual operation by the operator, the heightening seat 6 needs to be installed under the flange connecting block 1, and then the fixture is installed on the external machine tool or worktable via the second flange hole 61 of the heightening seat 6 to adjust the fixture to a suitable height. It can be seen that this finishing fixture for lowering the main boom can flexibly adapt to different processing height requirements through the heightening seat 6, effectively improving the versatility and practicality of the fixture.

[0045] The aforementioned riser seat 6 can be configured with multiple different height specifications to allow for replacement according to processing requirements.

[0046] See Figure 1 and Figure 2 As shown, based on the above embodiment, the riser 6 is coaxially arranged with the flange connecting block 1, and the riser 6 includes a flange portion 62 for connecting to an external machine tool. The flange portion 62 has a second flange hole 61, and there are at least two of both the second flange hole 61 and the first flange hole 11. At least two first flange holes 11 are arranged in a ring-shaped interval around the axis of the flange connecting block 1, and at least two second flange holes 61 are arranged in a ring-shaped interval around the axis of the riser 6. The diameter of the ring line of the first flange holes 11 is smaller than the diameter of the ring line of the second flange holes 61. Thus, the riser 6 and the flange connecting block 1 are coaxially arranged, enabling the riser 6 and the flange connecting block 1 to maintain a stable relative position when rotating or under force, avoiding vibration and errors caused by eccentricity or misalignment. Furthermore, the arrangement of the first flange holes 11 and the second flange holes 61 on ring lines of different diameters further enhances the versatility and compatibility of this tooling. In practical applications, different external machine tools or worktables may have mounting holes of different sizes and spacings. By setting flange holes with different ring diameters, the tooling can be connected to machine tools or worktables of various specifications.

[0047] See Figure 1 As shown, based on the above embodiment, the support 2 has a clearance recess 22, which is positioned opposite to and communicates with the first flange hole 11. Thus, the clearance recess 22 provides clearance for the first flange hole 11, avoiding interference with the connection operation of the flange connecting block 1.

[0048] See Figure 1 As shown, based on any of the above embodiments, the bottom end of the pressure cap 3 has at least one strip-shaped groove 32. In this way, the strip-shaped groove 32 can effectively reduce the contact area between the pressure cap 3 and the outer side of the settling main arm 5, so as to prevent the pressure cap 3 from damaging the outer side of the settling main arm 5, thereby affecting the production quality of the settling main arm 5.

[0049] 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.
