[0026] See also Figures 1 to 4, an alloy welding reamer structure provided by the utility model is now described. An alloy welding reamer structure includes a reamer seat 100 and a reamer tooth 200, the upper end surface of the reamer seat 100 is provided with a plurality of positioning holes 110, the rear end surface of the reamer tooth 200 is provided with an insertion slot 210, the reamer tooth 200 is mounted on the reamer seat 100 by means of the insertion slot 210, the upper end surface of the reamer tooth 200 is provided with a plurality of through holes 220, the plurality of through holes 220 are arranged one-to-one with the plurality of positioning holes 110, a welding plate 300 is arranged at the upper end of the reamer tooth 200, a plurality of positioning rods 310 are arranged at the lower end of the welding plate 300, the welding plate 300 is welded to the upper end surface of the reamer tooth 200, and the plurality of positioning rods 310 are passed through the plurality of through holes 220 one-to-one and inserted into the corresponding positioning holes 110.

[0027] The utility model provides an alloy welding reamer structure. Compared with the prior art, the reamer tooth 200 is mounted on the reamer seat 100 through the insertion groove 210, and the multiple positioning rods 310 on the lower end surface of the welding plate 300 correspond to the multiple through holes 220 penetrating the upper end surface of the reamer tooth 200, and are respectively inserted into the multiple positioning holes 110 on the upper end surface of the reamer seat 100. Finally, the welding plate 300 is welded and fixed on the upper end surface of the reamer tooth 200, and the reamer tooth 200 is stably installed on the reamer seat 100, and the reamer tooth 200 will not fall off from the reamer seat 100. The utility model provides an alloy welded reamer structure, in which a welding plate 300 is welded and fixed on a reamer tooth 200, so that a positioning rod 310 passes through a through hole 220 and is inserted into a positioning hole 110 of a reamer seat 100, so as to achieve stable installation of the reamer tooth 200 on the reamer seat 100, thereby greatly reducing the possibility of the reamer tooth 200 falling off from the reamer seat 100 during operation.

[0028] It is worth noting that the reamer teeth 200 in the present application are made of wear-resistant alloy materials, such as wear-resistant high manganese steel or wear-resistant high chromium cast iron, while the reamer seat 100 does not need to be made of wear-resistant alloy materials, and can be made of ductile cast iron.

[0029] See also Figure 4 The reamer seat 100 includes a main column 120 and side plates 130 arranged on both sides of the main column 120. The main column 120 and the two side plates 130 are integrally formed. The number of positioning holes 110 is an even number. The plurality of positioning holes 110 are symmetrically opened in pairs on the upper end surfaces of the two side plates 130. The plurality of positioning rods 310 are correspondingly inserted into the plurality of positioning holes 110 to form symmetrical positioning of the side plates 130 on both sides, thereby ensuring the stability of the installation of the reamer teeth 200 and the reamer seat 100.

[0030] The depth of the positioning hole 110 is greater than half the thickness of the side plate 130, ensuring that the positioning rod 310 has sufficient depth to be inserted into the positioning hole 110 of the side plate 130, thereby preventing the positioning rod 310 from being laterally dislodged due to being inserted into the positioning hole 110 at a shallow depth.

[0031] Preferably, the inner contour of the insertion slot 210 is matched with the outer contour of the reamer seat 100, so as to reduce the circumferential shaking of the reamer teeth 200 relative to the reamer seat 100. In addition, the depth of the insertion slot 210 is greater than the length of the reamer seat 100. When the reamer seat 100 is fully inserted into the insertion slot 210, there is still a certain distance between the end of the reamer seat 100 and the bottom of the insertion slot 210, so as to avoid the interference between the end of the reamer seat 100 and the bottom of the insertion slot 210, so as to prevent the positioning rod 310 from being inserted into the positioning hole 110.

[0032] See also Figure 4 The upper end surface of the reamer tooth 200 is provided with a groove 230, and a plurality of through holes 220 are provided at the bottom of the groove 230. The welding plate 300 is located in the groove 230, and a plurality of positioning rods 310 on the lower end surface of the welding plate 300 penetrate the corresponding through holes 220. At this time, the upper end surface of the welding plate 300 is flush with the upper end surface of the reamer tooth 200, so that the welding operation on the welding plate 300 is convenient.

[0033] In addition, the outer contour of the welding plate 300 is adapted to the inner contour of the groove 230 to prevent the welding plate 300 from shaking laterally in the groove 230 , while also providing corresponding positioning for the positioning rod 310 to pass through the through hole 220 .

[0034] Preferably, a protrusion 240 is provided in the middle of the groove 230, and a positioning hole 320 which is plugged into and matched with the protrusion 240 is opened in the middle of the welding plate 300. The protrusion 240 and the positioning hole 320 are plugged into and matched with each other, and can also form a positioning in which the positioning rod 310 is plugged into and matched with the through hole 220.

[0035] Specifically, the welding plate 300 and the groove 230 are circumferentially welded to form an external welding area 330, and the protrusion 240 and the positioning socket 320 are circumferentially welded to form an internal welding area 340. After the welding plate 300 is installed, the outer periphery of the welding plate and the outer periphery of the protrusion 240 are welded respectively to form the above-mentioned external welding area 330 and internal welding area 340. The two welding areas can greatly improve the installation stability of the welding plate 300 in the groove 230.

[0036] Preferably, the periphery of the welding plate 300 and the periphery of the protrusion 240 are both provided with transition fillets 350. The presence of the transition fillets 350 can avoid the formation of sharp angles on the periphery of the welding plate 300 and the periphery of the protrusion 240, so as to make the welding operation more convenient to operate.

[0037] See also Figure 1 There is an anti-interference gap 250 between the lower end of the positioning rod 310 and the bottom of the positioning hole 110. The anti-interference gap 250 can prevent the lower end of the positioning rod 310 from touching the bottom of the positioning hole 110, resulting in the welding plate 300 being unable to fully contact the bottom of the groove 230 or the upper end surface of the reamer tooth 200, thereby affecting the welding operation of the welding plate 300.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
