[0031] Furthermore, the terms "first" and "second" are used only to distinguish between different terms in description and do not have any special meaning.

[0032] like Figure 1 As shown, the semi-circular furnace liner positioning fixture of this embodiment mainly includes: a bracket 1, an inner liner 2 mounted on the bracket 1, a clamping assembly 3, and a driving mechanism 4. Specifically, the bracket 1 is used to integrate the inner liner 2, the clamping assembly 3, and the driving mechanism 4 into one unit, and then connects to the moving platform of the automated machining center through the bracket 1 to realize the automated processing of the product; the inner liner 2 is used to support the inner wall of the semi-circular furnace liner (hereinafter referred to as the product); the clamping assembly 3 is mounted on the bracket 1 and is used to contact the outer wall of the semi-circular furnace liner, thereby cooperating with the inner liner 2 to reliably clamp and position the semi-circular furnace liner; the driving mechanism 4 is mounted on the bracket 1, and its output shaft is fixedly connected to the inner liner 2. The driving mechanism 4 can drive the inner liner 2 to move toward or away from the clamping assembly 3, thereby realizing the loading, unloading, and clamping of the semi-circular furnace liner.

[0033] Using the above solution, the semi-circular furnace liner positioning fixture in this embodiment supports and clamps the product from the inside and outside by means of the inner liner 2 and the clamping component 3. The positioning effect of the product is good and reliable. After the product is positioned by the positioning fixture, it can be placed on the saw to process the cross section at the opening. The efficiency is increased by more than 50% compared with the previous engraving machine processing.

[0034] like Figure 1As shown, the support 1 includes a vertically connected base plate 11 and side plate 12. The base plate 11 is connected to the working platform of the saw, which is a movable platform that moves back and forth, driving the positioning fixture to move as a whole, thus moving the product. The clamping assembly 3 and the drive mechanism 4 are mounted on the side plate 12 of the support 1.

[0035] Combination Figure 1 and Figure 2 As shown, the inner liner 2 includes a connecting portion 21 and a supporting portion 22. The connecting portion 21 is connected to the output shaft of the drive mechanism 4, and the supporting portion 22 has a first arc-shaped wall surface that contacts the inner wall of the product. Specifically, in this embodiment, the inner liner 2 can be an integrally formed semi-cylindrical structure. The diameter of the inner liner 2 is slightly smaller than the diameter of the product to be processed. The diameter of the inner liner 2 is maximized to increase the contact area with the product and improve the support effect, while ensuring that processing is not affected. Of course, the width of the first arc-shaped wall surface is also preferably approximately the same as the width of the product.

[0036] like Figure 2 As shown, the drive mechanism 4 includes a first mounting base 41, a lead screw motor 42, and a nut seat 43. The first mounting base 41 is fixedly connected to the bracket 1. The lead screw motor 42 is connected to the first mounting base 41, and the lead screw of the lead screw motor 42 is perpendicular to the side plate 12 of the bracket 1. The nut seat 43 is connected to the lead screw of the lead screw motor 42, and the connecting part 21 of the inner liner 2 is connected to the nut seat 43. When the lead screw motor 42 is activated, it can drive the inner liner 2 to move towards or away from the clamping assembly 3 mounted on the side plate 12, thereby achieving product clamping and release.

[0037] Combination Figure 3 and Figure 4 As shown, the clamping assembly 3 includes a second mounting base and a clamping member 32. The second mounting base is connected to the side plate 12 of the bracket 1, and the clamping member 32 is connected to the mounting base. The clamping member 32 has a second arcuate wall surface for contacting the outer wall of the product. Preferably, the clamping assembly 3 is detachably connected to the side plate 12 of the bracket 1, and its position on the side plate 12 is adjustable to accommodate products of different sizes.

[0038] Specifically, such as Figure 1 and Figure 4As shown, the side plate 12 is provided with a sliding groove 121, and the second mounting base is fixedly connected to the sliding groove 121 by fasteners. Furthermore, the second mounting base includes an inner plate 311, an outer plate 312, and a pipe fitting. The inner plate 311 is disposed in the sliding groove 121 of the side plate 12 of the bracket 1, and the outer plate 312 is disposed outside the sliding groove 121 and connected to the inner plate 311 by a first bolt 313 and a nut. One end of the pipe fitting is connected to the outer plate 312, and the other end is connected to the clamping member 32. A spring 316 is provided inside the pipe fitting. One end of the spring 316 abuts against the outer plate 312, and the other end abuts against the clamping member 32. Using the above solution, the second mounting base can be slid along the slide groove 121 to a suitable position according to the size of the product, and then the second mounting base can be fixed on the side plate 12 by tightening the bolts; by connecting the outer plate 312 (or the second mounting base) and the clamping member through the spring 316, the product can make flexible contact with the clamping member 32 when clamping the product, so as to avoid the product being damaged by the clamping member 32.

[0039] like Figure 3 and Figure 4 As shown, the pipe fitting includes a first sleeve 314 and a second sleeve 315 fitted inside it. The first sleeve 314 is connected to the outer plate 312 of the second mounting base, the clamping member 32 is connected to the second sleeve 315, and the aforementioned spring 316 is disposed inside the second sleeve 315. Furthermore, the first sleeve 314 has an oblong hole, through which a second bolt 317 passes. The tail of the second bolt 317 is fixedly connected to the second sleeve 315, and the head of the second bolt 317 is spaced apart from the first sleeve 314 on its outer side. The diameter of the second bolt 317 is smaller than that of the oblong hole, thus allowing the second bolt 317 to move along the length of the oblong hole. By adopting the above solution, by setting the first sleeve 314 and the second sleeve 315 in a movable connection, it can be ensured that the spring 316 located in the second sleeve 315 can extend and retract, and the second bolt 317 set in the waist-shaped hole can limit the movement of the second sleeve 315 and prevent the second sleeve 315 from detaching from the first sleeve 314.

[0040] In summary, the usage process of the semi-circular furnace liner positioning fixture in this embodiment is as follows: Select a matching inner liner 2 according to the inner diameter of the product to be processed and install it on the nut seat 43; fix the base plate 11 of the bracket 1 to the platform of the processing equipment (saw); place the product on the clamping member 32 so that the outer wall of the product abuts against the second arc wall surface of the clamping member 32 (at this time, personnel need to manually hold the product to prevent it from falling); operate the screw motor 42 by the button to control the inner liner 2 to move towards the product so that the inner liner 2 abuts against the inner wall of the product; move the platform of the processing equipment to process the cross section of the opening of the product by the saw blade.
