Description
Technical Field

Background
The mining chain wheel is an important part for the transmission of the mining scraper conveyor and the reversed loader, and as the conveyor traction chain is driven by the chain wheel, when the chain wheel rotates, the gear teeth are meshed with the chain ring in sequence to drag the scraper chain to continuously move so as to play a role in conveying; the sprocket is subjected to the maximum torque of the whole equipment in operation, and is subjected to pulsating load and additional load. The compactness of the engagement of the pockets with the chain directly influences the transmission quality. The sprocket is generally machined by means of profiling flame gas cutting. During processing, a profiling template with the same size as the chain wheel is manufactured, a blank plate to be processed is placed below the profiling template, and then a gas cutting tool is operated to move along the edge of the profiling template, so that the chain wheel identical to the profiling template is cut. The key procedure of profiling flame gas cutting is to determine a gas cutting reference, that is, a cutting start point on a workpiece blank. If the gas cutting reference deviates, the center of the cut sprocket shifts. As such, the sprocket and chain become engaged with each other with a misalignment, which results in wear of the sprocket and chain. Typically, the sprocket is annular. The chain nest of the even-tooth chain wheel is opposite to the chain nest, the gear teeth of the chain wheel are opposite to the gear teeth, and the centers of the two opposite chain nests or the connecting lines of the gear teeth are the center of the chain wheel. The gas cutting reference is better found. Because of the structural limitation, the chain nest is opposite to the gear teeth of the chain wheel, the midpoint of the connecting line between the bottom of the chain nest and the gear tooth top of the chain wheel is not coincident with the center of the chain wheel, and the hollow part of the chain wheel is difficult to determine the center position, so that the cutting reference is easy to deviate.

In a preferred embodiment, a secondary positioning disk 30 is provided on the profiling template 20, and if the secondary positioning disk 30 is provided too much, positioning interference may occur.
Further, the upper end of the positioning gun 50 is provided with a positioning magnetic wheel, and the first auxiliary guiding long hole 202 and the second auxiliary guiding long hole 302 are provided with guiding tracks matched with the positioning magnetic wheel, so that the positioning magnetic wheel can move along the first auxiliary guiding long hole 202 or the second auxiliary guiding long hole 302 under the guidance of the guiding tracks.
Further, the auxiliary positioning plate 30 is provided with a positioning boss 303, and the second auxiliary guiding slot 302 is located in the positioning boss 303.
In the case of profiling flame gas cutting, the center of the profiling template 20 needs to be aligned with the center of the workpiece blank 70, so that the center of the workpiece blank 70 after cutting does not deviate. The teeth of the prior art odd tooth profiling template 20 are opposite to the other side of the profiling template 20, and the diameter of the profiling template 20 is difficult to measure, so the center of the profiling template 20 cannot be found by measuring the diameter of the profiling template 20. At the same time, the profiling template 20 and the workpiece blank 70 are hollow, and it is not possible to determine whether they are facing each other by marking the centers of the profiling template 20 and the workpiece blank 70. The profiling template 20 of the sprocket gas cutting positioning auxiliary device 10 is provided with an auxiliary positioning disc 30, the auxiliary positioning disc 30 is an arc-shaped plate, and the diameter of the outer arc of the auxiliary positioning disc 30 is the same as the diameter of the addendum circle of the profiling template 20. By positioning the auxiliary positioning disk 30 at the chain nest of the profiling template 20 and complementing the chain nest opposite to one of the chain teeth. In this way, it is possible to facilitate measurement of the diameter of the arc-shaped template, determination of the center of the arc-shaped template, and measurement of the distance from any point on the second auxiliary guide long hole 302 of the auxiliary positioning disk 30 to the tip circle. The workpiece blank 70 and the auxiliary positioning disk 30 are respectively provided with a first auxiliary long guide hole 202 and a second auxiliary long guide hole 302, and the first auxiliary long guide hole 202 and the second auxiliary long guide hole 302 are positioned on the symmetry axis of the profiling template 20. In this manner, positioning gun 50 is conveniently positioned on auxiliary positioning disk 30 or profiling template 20 so that the relative position of profiling template 20 and workpiece blank 70 is determined by the cooperation of positioning gun 50. Because the positioning gun 50 is vertically disposed, the horizontal relative position of the contoured template 20 to the workpiece blank 70 can be determined by the positioning gun 50. The positioning gun 50 is in the first auxiliary guide slot 202 or the second auxiliary guide slot 302 due to the crossed positioning lines and the concentric circles on the workpiece blank 70. The positioning gun 50 moves along the first auxiliary guide slot 202 or the second auxiliary guide slot 302, and during the movement, the positioning rod 60 below the positioning gun 50 moves along the crossed positioning line by moving the workpiece blank 70 or the profiling template 20, so that the symmetry axis of the profiling template 20 and the symmetry axis of the workpiece blank 70 are on the same line, and the center of the profiling template 20 and the center of the workpiece blank 70 are also on the same line. Thus, the center of the profiling template 20 and the center of the workpiece blank 70 can be overlapped by only moving the profiling template 20 and the workpiece blank 70 on the straight line. Since the distance from any point on the first auxiliary long guide hole 202 or the second auxiliary long guide hole 302 to the edge of the addendum circle of the profiling template 20 can be measured, and the distance from any point on the intersecting positioning line of the workpiece blank 70 to the concentric circle line can be measured, two symmetrical points on the intersecting positioning line can be found by measurement, and then the distance between the position of the first auxiliary long guide hole 202 or the second auxiliary long guide hole 302 where the positioning gun 50 is located and the addendum circle can be measured by matching the positioning gun 50 according to the two symmetrical points, and by adjusting the profiling template 20, the distance between the first auxiliary long guide hole 202 and the addendum circle and the distance between the second auxiliary long guide hole 302 and the addendum circle are the same, the fact that the centers of the profiling template 20 and the workpiece blank 70 are opposite is described, and thus the positioning reference is determined. The subsequent gas cutting gun performs gas cutting on the workpiece blank 70 along the edge of the profiling template 20, and the center of the chain wheel obtained by gas cutting is the center of the original workpiece die blank, so that the deviation between the center of the chain wheel after gas cutting and the center of the original workpiece die blank is avoided, the abrasion of the chain wheel and the chain is reduced, and the service life of the chain wheel is prolonged.
