Technical Field

[0001] This utility model relates to the field of grab bucket processing, specifically to a bucket lobe positioning fixture. Background Technology

[0002] Grab buckets are often equipped with arc-shaped flaps to ensure a tight seal when closed, allowing them to hold more material and improving volumetric efficiency. However, precise positioning of the grab bucket body and flaps during welding presents challenges, making it difficult to locate the welding equipment.

[0003] Therefore, providing a bucket positioning fixture that can accurately position the grab body and the bucket petal body to facilitate the positioning of welding equipment is a problem that this utility model urgently needs to solve. Utility Model Content

[0004] The purpose of this invention is to provide a bucket-petal positioning fixture, which solves the problem that it is difficult to accurately position the bucket body and the bucket petal body when welding them, which leads to difficulties in positioning the welding equipment.

[0005] To achieve the above objectives, this utility model provides a bucket-petal positioning fixture, which includes a base, on which a plurality of support plates are arranged around the base. The upper end of the support plates is recessed downward to form a first groove for engaging the grab bucket body, and the end of the first groove is recessed downward to form a second groove for engaging the bucket petal body.

[0006] This ensures that the inner arc surface of the grab bucket body fits into the outer arc surface of the bucket petal body.

[0007] Preferably, the support plate is provided with a first clamp on its side, so that the first clamp can press the lobes against the side wall of the second groove.

[0008] Preferably, the first clamp includes a threaded seat disposed on the side of the support plate and a locking screw engaged with the threaded seat;

[0009] This allows the locking screw to press the bucket body tightly against the side wall of the second groove.

[0010] Preferably, one end of the locking screw is provided with a metal pressure block, and the other end is provided with a rotating handle.

[0011] Preferably, one end of the base is provided with a support column, and the other end is provided with a support seat, and the support seat is provided with a quick clamp;

[0012] One end of the grab bucket is placed on the support column, and the other end is pressed onto the support base by the quick clamp.

[0013] Preferably, a screw hole is formed at the upper end of the support column;

[0014] A pressure plate is provided on the support column, and a screw is provided on the lower end face of the pressure plate. The screw passes through the pin hole at the end of the grab body and is screwed into the screw hole.

[0015] Preferably, the plurality of support plates are connected by an arc-shaped plate.

[0016] This utility model provides a bucket-petal positioning fixture, which includes a base with multiple support plates arranged around it. The upper end of each support plate is recessed to form a first groove for engaging the grab bucket body, and the end of the first groove is recessed to form a second groove for engaging the bucket petal body. This ensures that the inner arc surface of the grab bucket body is in close contact with the outer arc surface of the bucket petal body. During operation, the bucket petal body is engaged in the second groove of the multiple support plates, and then the grab bucket body is engaged in the first groove of the multiple support plates, resulting in a tight fit between the inner arc surface of the grab bucket body and the outer arc surface of the bucket petal body, facilitating welding operations at the joint between the two parts.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0026] like Figure 1-4 As shown: This utility model provides a bucket-petal positioning fixture, which includes a base 1, on which multiple support plates 2 are arranged around the base 1. The upper end of each support plate 2 is recessed downward to form a first groove 11 for engaging a grab bucket body 9, and the end of the first groove 11 is recessed downward to form a second groove 12 for engaging a bucket petal body 10, so that the inner arc surface of the grab bucket body 9 is in close contact with the outer arc surface of the bucket petal body 10. During operation, the bucket petal body is engaged in the second groove of the multiple support plates, and then the grab bucket body is engaged in the first groove of the multiple support plates, so that the inner arc surface of the grab bucket body and the outer arc surface of the bucket petal body are tightly fitted, which facilitates the welding equipment to perform welding operations at the joint between the two.

[0027] In a preferred embodiment of this utility model, in order to effectively press the hopper body 10 into the second groove of the support plate and prevent it from shifting during welding, a first clamp 3 is provided on the side of the support plate 2, so that the first clamp 3 can press the hopper body 10 into the side wall of the second groove 12.

[0028] In a preferred embodiment of this utility model, the first clamp 3 includes a threaded seat 14 disposed on the side of the support plate 2 and a locking screw 13 engaged with the threaded seat 14; such that the locking screw 13 can press the bucket body 10 against the side wall of the second groove 12. After the bucket body is engaged in the second groove, the locking screw is twisted so that its end presses the bucket body against the side wall of the second groove.

[0029] In a preferred embodiment of this utility model, a metal pressure block 15 is provided at one end of the locking screw 13, and a rotating handle 16 is provided at the other end.
