Description

Technical Field

[0001] This utility model relates to the field of calibration fixtures, and in particular to a calibration fixture for welding a spinning box pump base. Background Technology

[0002] The spinning box is one of the main components of a melt spinning machine. Its main function is to keep the melt distribution pipe, metering pump, and spinning head assembly in the spinning box warm. During the welding process of the spinning box, the welding of the pump base is a critical step. The pump base is welded to one end of the sleeve on the spinning box to facilitate the subsequent installation of the pump and the pump base.

[0003] However, during welding, deviations in the placement of the pump base and welding factors can cause the pump base to be welded crookedly. Misalignment between the pump base and the sleeve will directly lead to difficulties in installing the intermediate plate and prevent the drive shaft from working properly. Without suitable tooling, the entire debugging process is very time-consuming and labor-intensive, thus affecting subsequent assembly and debugging. Utility Model Content

[0034] 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.

[0035] This utility model provides, for example Figure 1-5The illustrated calibration fixture for welding a spinning box pump base includes a spinning box body 1. A welding sleeve 11 is fixedly connected inside the spinning box body 1. A welding pump base 2 is fixedly connected to one end of the welding sleeve 11. A calibration assembly 3 for calibrating the welding pump base 2 is disposed inside the welding sleeve 11. The calibration assembly 3 includes a fixture guide rod 31, a calibration base 32, a calibration structure 33, a level 34, and a connecting assembly 35. The calibration base 32 is fixedly connected to one end of the fixture guide rod 31. One side of the calibration base 32 is aligned with the welding pump base 2, and the opposite side of the calibration base 32 corresponds to the opposite side of the welding pump base 2. That is, when the calibration base 32 is aligned with the welding pump base 2... The calibration base 32 can be directly snapped into the center of the welding pump base 2. The calibration structure 33 is sleeved on the outside of the tooling guide rod 31. The calibration structure 33 is used in conjunction with the welding sleeve 11 to verify the concentricity of the welding pump base 2 and the welding sleeve 11. The level 34 is installed on the outside of the tooling guide rod 31 through the connecting assembly 35. The level 34 is used to verify the verticality of the welding pump base 2. The level 34 is a bubble-type level. That is, when the calibration base 32 is in close contact with the welding pump base 2, the tooling guide rod 31 and the welding pump base 2 are in a vertical state. The level 34 detects the inclination of the tooling guide rod 31, and thus detects the vertical inclination of the welding pump base 2.

[0036] In particular, the verification structure 33 includes a verification disk 331 and a connecting sleeve 332. The verification disk 331 is located inside the welding sleeve 11. One end of the outer wall of the connecting sleeve 332 is fixedly connected to the verification disk 331. The connecting sleeve 332 is slidably sleeved on the outside of the tooling guide rod 31. That is, by observing the gap between the verification disk 331 and the inner wall of the welding sleeve 11, the concentricity of the welding pump seat 2 and the welding sleeve 11 can be obtained. That is, the more uniform the gap between the verification disk 331 and the inner wall of the welding sleeve 11, the higher the concentricity of the welding pump seat 2 and the welding sleeve 11.

[0037] Furthermore, the connecting assembly 35 includes a connector 351, a fixing plate 352, and a fixing block 353. The connector 351 is slidably sleeved on the outside of the tooling guide rod 31. The fixing plate 352 is fixedly connected to the end of the connector 351. The fixing block 353 is fixedly connected to the side of the level 34. The top of the fixing plate 352 has symmetrically opened slots that match the fixing block 353. The connector 351 is sleeved on the outside of the tooling guide rod 31, which can improve the stability of the level 34 mounted on the tooling guide rod 31. It also includes a connecting block 354 and a locking rod 355. The bottom of the fixing plate 352 has an installation groove. The connecting block 354 is slidably disposed inside the installation groove. One end of the locking rod 355 is fixedly connected to the connecting block 354. A locking hole is provided on one side of the fixing block 353. The outer wall of the locking rod 355 is slidably engaged with the inner cavity of the locking hole. The engagement of the locking rod 355 with the fixing block 353 can keep the fixing block 353 and the fixing plate 352 in a stable connection state, thereby ensuring the stability of the splicing of the level 34 and the connecting piece 351.

[0038] Furthermore, the connecting assembly 35 also includes a winding shaft 356 and a connecting rope 357. The winding shaft 356 is rotatably mounted inside the mounting groove. A knob is fixedly connected to one end of the winding shaft 356. The end of the connecting rope 357 is fixedly connected to the connecting block 354 and the winding shaft 356 respectively. By rotating the knob, the winding shaft 356 can wind up the connecting rope 357, thereby causing the connecting rope 357 to pull the connecting block 354 and the locking lever 355, causing the locking lever 355 to separate from the fixed block 353. The connecting assembly 35 also includes a limiting block 359 and a limiting spring 358. The limiting block 359 is fixedly connected to the inside of the mounting groove. A cable routing hole matching the connecting rope 357 is opened on one side of the limiting block 359. The limiting spring 358 is slidably sleeved on the outside of the connecting rope 357. The limiting spring 358 is located between the limiting block 359 and the connecting block 354. The limiting spring 358 can give the connecting block 354 an elastic compressive force, thereby ensuring the stability of the locking rod 355 and the fixing block 353.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
