[0037] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0038] See also Figure 1-Figure 3 , shows a hopper welding assembly fixture of a preferred embodiment of the present invention, which is used to assemble and position the hopper 50, wherein, see Figure 12-14 The hopper 50 includes a hopper body 51, two shaft seats 52 and two wall panels 53. The hopper body 51 is provided with a material cavity 511, a feed port 512 and a discharge port 513. Two opposite sides of the hopper body 51 are provided with shaft seat holes connected to the material cavity 511, and the other two opposite sides of the hopper body 51 are provided with wall panel mounting parts. The hopper body 51 can be an integral structure or include at least two split bodies, and the at least two split bodies are spliced ​​to form the hopper body 51.

[0039] Continue to see Figure 1-Figure 3 In the illustrated embodiment, the hopper welding assembly fixture includes: a bucket body positioning structure 10, which is used to position the bucket body 51, including a bucket body positioning member 11 and two shaft seat hole positioning members 12, the bucket body positioning member 11 is used to cooperate with the inner wall of the bucket body 51, and the shaft seat hole positioning member 12 is used to correspond to the position of the shaft seat hole and be located in the bucket body 51 when the bucket body 51 is positioned; two shaft seat positioning structures 20, the two shaft seat positioning structures 20 are arranged oppositely and separately On the opposite sides of the bucket body positioning structure 10 close to the shaft seat hole positioning piece 12, the shaft seat positioning structure 20 is used to move the shaft seat 52 to the shaft seat hole of the bucket body 51 and make the shaft seat 52 and the bucket body 51 abut against each other; there are two wall panel positioning structures 30, and the two wall panel positioning structures 30 are relatively arranged and disposed on the opposite sides of the bucket body positioning structure 10 away from the shaft seat hole positioning piece 12. The wall panel positioning structure 30 is used to move the wall panel 53 to abut against the wall panel mounting part of the bucket body 51.

[0040] When the hopper welding assembly fixture of the present invention is used, the hopper body 51 is first buckled on the hopper body positioning structure 10 with the feed port 512 facing downward and the discharge port 513 facing upward, so that the hopper body positioning member 11 and the inner wall of the hopper body 51 are matched, and at the same time, the shaft seat hole positioning member 12 and the shaft seat hole position on the hopper body 51 correspond to each other, so as to achieve accurate positioning of the hopper body 51. Then, the shaft seat 52 is placed on the shaft seat positioning structure 20, and the wall panel 53 is placed on the wall panel positioning structure 30. The shaft seat 52 is transferred to the shaft seat hole position of the hopper body 51 through the shaft seat positioning structure 20, and the shaft seat 52 and the hopper body 51 are abutted at the same time, so as to achieve accurate positioning of the shaft seat 52. For positioning and clamping, the wall panel 53 is transferred to the wall panel mounting portion of the bucket body 51 through the wall panel positioning structure 30 to abut against the wall panel mounting portion to achieve positioning and clamping of the wall panel 53. Therefore, this structure can replace manual assembly and positioning of the bucket 50, is more convenient for welding, and improves the welding efficiency and quality of the bucket 50. At the same time, it is safer and easier to promote and apply. In addition, the bucket body positioning structure 10, the axle seat positioning structure 20 and the wall panel positioning structure 30 act together on the bucket 50 to apply a force to the bucket 50 that can control the reverse deformation of the bucket 50 during the welding process, prevent the bucket 50 from deforming, and thus can further improve the welding quality.

[0041] Continue to see Figure 1-Figure 3 In the illustrated embodiment, the bucket welding assembly fixture also includes a first seat body 40, and the bucket body positioning structure 10, the shaft seat positioning structure 20 and the wall panel positioning structure 30 are all arranged on the first seat body 40, and the bucket body positioning structure 10 is arranged between the shaft seat positioning structure 20 and the wall panel positioning structure 30.

[0042] In the illustrated embodiment, when the shaft seat positioning structure 20 transfers the shaft seat 52 to the shaft seat hole of the bucket body 51, the shaft seat hole positioning member 12 and the shaft seat 52 abut against each other to clamp the shaft seat 52 together with the shaft seat positioning structure 20. Since the shaft seat hole positioning member 12 can abut against the shaft seat 52, the shaft seat hole positioning member 12 can be used to limit the axial position of the shaft seat 52 to limit the depth of the shaft seat 52 inserted into the shaft seat hole, thereby achieving precise positioning of the shaft seat 52 with higher positioning accuracy. At the same time, the shaft seat hole positioning member 12 can apply a thrust toward the shaft seat positioning structure 20 to the shaft seat 52. Therefore, the shaft seat hole positioning member 12 and the shaft seat 52 abut against each other to offset part of the resistance force applied to the shaft seat 52 by the shaft seat positioning structure 20, thereby preventing the portion of the bucket body 51 close to the shaft seat hole from deforming, which helps to further improve the welding quality.

[0043] See also Figure 4-Figure 5The bucket body positioning member 11 includes a first bucket body positioning member 111 arranged vertically, the first bucket body positioning member 111 includes a base 1111 arranged on the first base body 40 and a bucket body positioning member 1112 detachably arranged on the base 1111, the top of the bucket body positioning member 1112 is adapted to the inner wall of the bucket body 51, and the first bucket body positioning member 111 is arranged vertically, so that the bucket body 51 can be reliably supported by the first bucket body positioning member 111 to realize the positioning of the bucket body 51, and at the same time, based on the top of the bucket body positioning member 1112 The bucket body 51 is adapted to the inner wall of the bucket body 51, so that the inner wall of the bucket body 51 can fit with the top of the bucket body positioning component 1112, which can prevent welding deformation and help to further improve the welding quality. In addition, based on the fact that the bucket body positioning component 1112 can be detachably mounted on the base 1111, different bucket body positioning components 1112 can be replaced according to buckets 50 of different shapes and / or sizes. Therefore, the bucket welding assembly clamp can be suitable for different buckets 50, with a wider range of applications, the advantage of ultra-high flexibility, and is more conducive to promotion and application.

[0044] In the illustrated embodiment, four first bucket body positioning members 111 are provided, and two adjacent first bucket body positioning members 111 are arranged laterally apart, which helps to improve the positioning accuracy of the bucket body 51, and at the same time, the bucket body 51 can better fit the bucket body positioning member 1112, thereby further improving the welding quality. Of course, in other embodiments, the first bucket body positioning members 111 can also be provided with one to three or more than five, which can be selected according to actual conditions and are not limited thereto.

[0045] Of course, in other embodiments, the first bucket body positioning component 111 may be an integrated structure or the bucket body positioning component 1112 and the base 1111 may be fixedly connected, so that the bucket welding assembly fixture can be applicable to a bucket 50.

[0046] See also Figure 5-Figure 6 In the present embodiment, a first positioning structure for positioning the bucket body positioning component 1112 is provided between the bucket body positioning component 1112 and the base 1111 to realize positioning of the bucket body positioning component 1112 and accurate and rapid installation of the bucket body positioning component 1112, thereby facilitating improving the positioning accuracy of the bucket body 51.

[0047] Specifically, the first positioning structure includes a first positioning hole 11121 and a first positioning member inserted in the first positioning hole 11121 . One of the first positioning hole 11121 and the first positioning member is disposed on the bucket body positioning component 1112 , and the other is disposed on the base 1111 .

[0048] Specifically, in the illustrated embodiment, the first positioning member is a first positioning pin 11111. Of course, in other embodiments, the first positioning member may be a positioning block or other applicable structures.

[0049] In this embodiment, the first bucket body positioning member 111 is further provided with a detachable connecting member, which connects the bucket body positioning member 1112 and the base 1111, which can ensure that the bucket body positioning member 1112 can be detached and reliably installed on the base 1111. Specifically, the detachable connecting member is a bolt, and the threaded end of the bolt passes through the connecting hole 11122 on the bucket body positioning member 1112 and is screwed to the threaded hole 11112 on the base 1111. Of course, in other embodiments, the detachable connecting member can be a screw or other applicable structure.

[0050] Continue to see Figure 4-Figure 5 The bucket body positioning member 11 also includes two second bucket body positioning members 112 arranged in the transverse direction. The two second bucket body positioning members 112 are symmetrically or relatively arranged and correspond one to one to fit with the corresponding parts of the inner side wall of the bucket body 51. The arrangement of this structure can further improve the positioning accuracy of the bucket body 51. At the same time, because the two second bucket body positioning members 112 are arranged relatively and act on the corresponding parts of the two opposite inner side walls of the bucket body 51 respectively, they can play a good anti-deformation role, prevent welding deformation, and help to further improve the welding quality. Of course, in other embodiments, there may be more than three second bucket body positioning members 112, and the ends of each second bucket body positioning member 112 correspond one to one to fit with the corresponding parts of the inner side wall of the bucket body 51. In this case, at least two second bucket body positioning members 112 are symmetrically or relatively arranged and correspond one to one to fit with the two opposite inner side walls of the bucket body 51.

[0051] Continue to see Figure 4-Figure 5 A second bucket body positioning piece 112 is provided on each shaft seat hole positioning piece 12. In actual applications, since the outer diameter of the shaft seat 52 is relatively small, when the shaft seat 52 is against the bucket body 51 under the action of the shaft seat positioning structure 20, a large force will be applied to the portion of the bucket body 51 near the shaft seat hole, causing it to be easily deformed. The second bucket body positioning piece 112 is provided on the shaft seat hole positioning piece 12 to provide anti-deformation support for the portion of the bucket body 51 near the shaft seat hole, thereby preventing welding deformation and helping to further improve the welding quality.

[0052] In this embodiment, the second bucket body positioning member 112 and the shaft seat hole positioning member 12 are coaxially arranged, and the outer diameter of the second bucket body positioning member 112 is larger than the outer diameter of the shaft seat hole positioning member 12. In this way, the force can be evenly applied to the part of the bucket body 51 near the shaft seat hole, and the anti-deformation effect is higher.

[0053] In this embodiment, the bucket body positioning member 11 also includes a third bucket body positioning member 113 arranged vertically. The third bucket body positioning member 113 is used to be inserted from bottom to top into the discharge port 513 of the bucket body 51 to further improve the positioning accuracy of the bucket body 51, which is conducive to further improving the welding quality.

[0054] See also Figure 7-Figure 8 In the present embodiment, the shaft seat positioning structure 20 comprises a shaft seat positioning member 21 and a first driving device 22; two shaft seat positioning columns 211 are provided on the shaft seat positioning member 21, and the shaft seat positioning column 211 is used to be inserted into the center hole of the shaft seat 52, the two shaft seat positioning columns 211 are coaxial and arranged in sequence along the axial direction, and the outer diameter of the one of the two shaft seat positioning columns 211 that is closer to the shaft seat hole positioning member 12 is smaller than the outer diameter of the other; the first driving device 22 is used to drive the shaft seat positioning member 21 to move in the direction of approaching and moving away from the shaft seat hole positioning member 12. When in use, the center hole of the shaft seat 52 and the adapted shaft seat positioning column 211 are matched to support and position the shaft seat 52, and then the first driving device 22 is used to drive the shaft seat positioning member 21 to move close to the bucket body 51, so as to place the shaft seat 52 on the shaft seat hole of the bucket body 51 and make the shaft seat 52 and the bucket body 51 abut against each other, so as to realize the pair positioning of the shaft seat 52 and the bucket body 51. At the same time, based on the fact that there are two shaft seat positioning columns 211, the shaft seat positioning structure 20 can adapt to two types of shaft seats 52, so that the adapted shaft seat 52 can be selected according to the hoppers 50 of different shapes and / or sizes, and the scope of application is wider. Of course, in other embodiments, the number of shaft seat positioning columns 211 can be one or more than three, which can be selected according to the specific situation and is not limited thereto.

[0055] In this embodiment, the shaft seat positioning structure 20 also includes a second driving device 23, which is used to drive the shaft seat positioning member 21 to perform vertical lifting movement. The second driving device 23 can be used to adjust the upper and lower positions of the shaft seat positioning member 21, which helps to improve the positioning accuracy of the shaft seat 52.

[0056] Specifically, the shaft seat positioning structure 20 also includes a second seat body 24, a first slide rail mechanism 27 and a second slide rail mechanism 28. The first slide rail mechanism 27 is arranged on the first seat body 40 and is arranged along the driving direction of the first drive device 22. The second seat body 24 is arranged on the slider of the first slide rail mechanism 27. The second slide rail mechanism 28 is arranged between the second seat body 24 and the shaft seat positioning member 21 and is arranged along the driving direction of the second drive device 23. In this way, the first slide rail mechanism 27 and the second slide rail mechanism 28 are used to guide the movement of the shaft seat positioning member 21 to ensure that the shaft seat positioning member 21 moves smoothly, which is beneficial to improve the positioning accuracy.

[0057] Specifically, the shaft seat positioning structure 20 also includes a third seat body 25 and a fourth seat body 26. The third seat body 25 is arranged on the first seat body 40, the first drive device 22 is arranged on the third seat body 25, the fourth seat body 26 is arranged on the second seat body 24, and the second drive device 23 is arranged on the fourth seat body 26.

[0058] Specifically, in this embodiment, the first drive device 22 and the second drive device 23 are both cylinders. Of course, in other embodiments, the first drive device 22 and the second drive device 23 can be commonly used drive structures such as hydraulic cylinders and electric push rods.

[0059] See also Figure 9-11 The wall panel positioning structure 30 includes a wall panel support positioning assembly 31 and a third driving device 32. The wall panel support positioning assembly 31 includes a support seat 311 and a wall panel positioning member 312 detachably arranged on the support seat 311. The wall panel positioning member 312 is used to support the wall panel 53. The third driving device 32 is connected to the support seat 311 and is used to drive the wall panel support positioning assembly 31 to move horizontally. When in use, the wall panel 53 is placed on the wall panel positioning member 312, and then the third driving device 32 is used to drive the wall panel support positioning assembly 31 to move so that the wall panel 53 and the wall panel mounting portion of the bucket body 51 are abutted against each other, thereby realizing the assembly and positioning of the wall panel 53 and the bucket body 51. At the same time, because the wall panel positioning member 312 can be detachably mounted on the support seat 311, the wall panel positioning member 312 is replaceable, so that different wall panel positioning members 312 can be replaced according to different shapes and / or sizes of hoppers 50, so that the hopper welding assembly fixture can be suitable for different hoppers 50, with a wider range of applications and more conducive to promotion and application.

[0060] In this embodiment, the wall panel positioning member 312 includes a mounting plate 3121, a wall panel positioning column 3122 and a supporting block 3123. The mounting plate 3121 can be detachably mounted on the support seat 311. The wall panel positioning column 3122 and the supporting block 3123 are both mounted on the mounting plate 3121. The wall panel positioning column 3122 is used to be inserted into the through hole of the wall panel 53. The supporting block 3123 is located below the wall panel positioning column 3122 and is used to abut against the bottom of the wall panel 53 to support the wall panel 53. When this is done, the through hole of the wall panel 53 and the wall panel positioning column 3122 are matched to realize supporting and positioning of the wall panel 53. At the same time, the position of the wall panel 53 is accurately determined by making the bottom of the wall panel 53 and the supporting block 3123 abut against each other, thereby realizing accurate positioning of the wall panel 53. The setting of the mounting plate 3121 can make the wall panel positioning column 3122 and the supporting block 3123 form a modular structure, which is convenient for the rapid replacement of the wall panel positioning member 312.

[0061] In this embodiment, the wall panel positioning member 312 also includes a plurality of positioning protrusions 3124 provided on the mounting plate 3121, and the positioning protrusions 3124 are arranged at intervals, and each positioning protrusion 3124 is used to abut against the end face of the wall panel 53 away from the mounting plate 3121. That is, when the wall panel 53 is mounted on the wall panel positioning column 3122 through the through hole, an end face of the wall panel 53 close to the support seat 311 abuts against the positioning protrusion 3124 to stably support the wall panel 53, so that the positioning effect of the wall panel 53 is better. When the wall panel 53 is transferred to the wall panel mounting portion of the bucket body 51 to abut against it, the setting of the positioning protrusion 3124 can make the wall panel 53 and the wall panel mounting portion of the bucket body 51 reliably fit, thereby helping to improve the welding quality. At the same time, the wall panel 53 and the support seat 311 are separated, which is more convenient for the welding operation after the wall panel 53 and the bucket body 51 are assembled, and the operation is more convenient.

[0062] In this embodiment, there are two pairs (ie, four) of positioning protrusions 3124, which are disposed at both ends of the wall panel positioning column 3122, and the two positioning protrusions 3124 in each pair of positioning protrusions 3124 are spaced apart from each other.
