[0002] The bucket mainly consists of an arc plate, ear plates, two side plates, and bucket teeth. The arc plate and the side plates are usually connected by welding. Since the working environment of the bucket is usually harsh and it faces large impacts and loads, the welding of the arc plate and the side plates of the bucket is mostly full welding, that is, the inner and outer sides of the part where the arc plate and the side plate are connected are welded.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN 220533383 U provides a bucket welding fixture, including two parallel and vertically erected bucket wall panel shaping arc plates. The bottom of the two bucket wall panel shaping arc plates is connected by a base plate. A blade slot is provided on the left side of the bucket wall panel shaping arc plate. Positioning seats are respectively provided on the left and right sides of the bucket wall panel shaping arc plate. The positioning seats are equipped with locking wedges. The upper part of the bucket wall panel shaping arc plate is arc-shaped, and the curvature of the arc is adapted to the inner contour of the large bucket. A positioning groove is provided on the right side of the bucket wall panel shaping arc plate. An ear plate positioning upright is provided on the right side of the positioning groove. Ear plate positioning pins are respectively provided on the upper and lower parts of the ear plate positioning upright. This technical solution can ensure the key important dimensions of the product welding positioning, improve welding efficiency and product quality.

[0004] When using the above welding fixtures, they can only be used for welding buckets of fixed sizes and models. They cannot be adapted to the bending curvature and length of the curved plate, as well as the shape of the side plate. Matching welding fixtures are required according to the bucket models produced, resulting in a large number of welding fixtures for production enterprises, which increases storage and management costs. Utility Model Content

[0005] To address the technical problem of inflexible use of bucket welding fixtures in the prior art, this utility model provides a fixture for bucket welding that can replace corresponding modules according to changes in bucket size and structure, eliminating the need for completely new fixtures and reducing storage and management costs.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a tooling for welding buckets, including a base plate, and further including: two side plate positioning components, each side plate positioning component being arranged opposite to each other and connected to the base plate; each side plate positioning component including a vertically arranged base plate, on which a force-applying member is provided, the force-applying member being able to press against the side plate of the bucket to be welded; the side plate positioning component further including a support plate, the support plate being movably disposed on the base plate, the support plate being used to support the side plate of the bucket to be welded; and an arc-shaped plate support component, the arc-shaped plate support component including: The assembly includes a connecting frame, which is disposed on the base plate and located between the two side plate positioning assemblies. The connecting frame is connected to the base plate, and a support plate is detachably connected to the connecting frame. The support plate is used to support the arc-shaped plate of the bucket to be welded. A support member is also provided on the support plate to support the bucket teeth to be welded. The assembly also includes an ear plate positioning assembly, which includes a support base. The support base is detachably connected to the base plate and located on one side of the connecting frame. A positioning shaft is detachably disposed on the support base, and the positioning shaft can pass through the ear plate of the bucket to be welded and the support base.

[0007] This utility model allows for the detachable connection of the support plate and support seat, enabling the replacement of matching support plates and support seats after changes in the size and structure of the bucket arc plate, bucket ear plate, and bucket teeth to be welded. This eliminates the need to replace all the tooling, achieving universality for the bottom plate and side plate positioning components. Only the support plate and support seat need to be equipped as required, reducing tooling storage and management costs.

[0008] Furthermore, the force-applying component is a hydraulic cylinder, and three force-applying components are horizontally arranged.

[0009] Furthermore, a guide is provided between each of the support bases and the connecting frame, and a guide groove is provided on the guide. The support plate moves up and down along the guide groove. An adjustment block is slidably provided at the bottom of the guide. The adjustment block can slide in the horizontal plane, and the upper surface of the adjustment block can abut against the lower end of the support plate.

[0010] This invention ensures smooth movement of the support plate by setting guide components, and ensures stability of the support plate after its position is changed by using adjustment blocks of different heights, so that it will not slip under the pressure of the side plate of the bucket to be welded.

[0011] Furthermore, the connecting frame includes two connecting plates arranged opposite to each other, the support plate is disposed on the outer side of the connecting plate, at least two threaded sleeves are disposed on the inner side of the connecting plate, and a corresponding number of connecting bolts are horizontally passed through the support plate, the connecting bolts passing through the support plate and connecting to the threaded sleeves.

[0012] Furthermore, the supporting plate is provided with three connecting bolts. The upper part of the supporting plate is provided with a connecting hole one, and the corresponding connecting bolt passes through the connecting hole one. The supporting plate is also provided with a connecting hole two and a connecting hole three, and the corresponding connecting bolts are respectively passed through the connecting hole two and the connecting hole three. The connecting hole one, the connecting hole two and the connecting hole three are all of the same type of loop hole.

[0013] This utility model uses a gourd-shaped hole as the through hole for the connecting bolt, which can compensate for the manufacturing error of this tooling and prevent the connecting bolt from failing to connect with the threaded sleeve on the connecting plate due to manufacturing errors.

[0014] Furthermore, a positioning rib is horizontally provided on the base plate, and a positioning groove is provided at the lower part of the support plate. The positioning rib can extend into the positioning groove. A clearance groove is also provided at the lower part of the support plate. The clearance groove is used to avoid the guide member at the corresponding position. The first connecting hole and the second connecting hole are connected to the corresponding clearance groove.

[0015] This invention can accurately limit the front and rear position of the support plate on the base plate by setting positioning ribs, and accurately match the arc plate of the bucket to be welded, thus solving the problem of low precision caused by the gap generated by the use of gourd holes.

[0016] Furthermore, an adjusting pad is provided between the support plate and the connecting plate. The two ends of the adjusting pad abut against the connecting plate and the support plate, respectively. The adjusting pad has a columnar structure and is snapped onto the connecting bolt.

[0017] This invention allows for adjustment of the left and right distance of the arc-shaped plate support assembly by setting adjustment pads, so that it matches the arc-shaped plate of the bucket to be welded, and ensures that the two support plates are always symmetrically arranged on both sides of the connecting frame, thereby improving the stability of the support.

[0018] Furthermore, the outer side of the support plate is horizontally equipped with limit bolt one and limit bolt two, which are detachably installed. Limit bolt one is opposite to the connecting hole two, and limit bolt two is opposite to the connecting hole three. Limit bolt one and limit bolt two can abut against the corresponding connecting bolts under the action of external force.

[0019] This utility model can prevent the support plate and the connecting bolt from moving relative to each other under the action of external force by setting limit bolt one, limit bolt two and limit bolt three.

[0020] Furthermore, the support member is a block structure, and an adjusting bolt runs through the support member. The end of the adjusting bolt can abut against the bucket teeth to be welded.

[0021] This utility model can adjust the position of the bucket teeth supported by the tooling by setting adjustment bolts, adapt to changes in the size of the bucket teeth to be welded, and compensate for manufacturing errors, ensuring the accuracy of the positioning of the bucket teeth to be welded.

[0022] Furthermore, a reinforcing plate is provided between the two connecting plates.

[0023] As can be seen from the above technical solutions, this utility model has the following advantages: This utility model provides a tooling for bucket welding. Through the detachable connection of the support plate and support seat, it allows for replacement of the matching support plate and support seat after changes in the size and structure of the bucket's arc plate, ear plate, and teeth, without requiring a complete replacement of the tooling. This achieves universality for the bottom plate and side plate positioning components, requiring only the support plate and support seat as needed, reducing tooling storage and management costs. Guide components ensure smooth movement of the support plate, and adjusting blocks of different heights ensure stability after position changes, preventing slippage under pressure from the bucket's side plate. Using a gourd-shaped hole as the through hole for the connecting bolts compensates for manufacturing errors, preventing bolts from failing to connect due to manufacturing defects. The screw sleeve connection on the plate; by setting positioning ribs, the front and rear positions of the support plate on the base plate can be accurately limited, and it can accurately match the arc plate of the bucket to be welded, solving the problem of low precision caused by the gap generated by the use of the hoist hole; by setting adjustment shims, the left and right distance of the arc plate support assembly can be adjusted to match it with the arc plate of the bucket to be welded, and to ensure that the two support plates are always symmetrically set on both sides of the connecting frame, improving the stability of the support; by setting limit bolt one, limit bolt two and limit bolt three, relative movement between the support plate and the connecting bolt under the action of external force can be prevented; by setting adjustment bolts, the position of the bucket teeth of the bucket to be welded supported by this tooling can be adjusted to adapt to the size changes of the bucket teeth, and to compensate for manufacturing errors, ensuring the accuracy of the positioning of the bucket teeth.

[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0032] like Figure 1 and Figure 2As shown in the figure, this specific embodiment provides a tooling for bucket welding, including a base plate 2, a side plate positioning assembly 1, an arc-shaped plate support assembly 7, and an ear plate positioning assembly 5. Two side plate positioning assemblies 1 are arranged opposite each other and are both connected to the base plate 2. Each side plate positioning assembly 1 includes a vertically arranged base plate 101, which is welded to the base plate 2. A force-applying member 102 is provided on the base plate 101, which can press against the side plate 11 of the bucket to be welded. In this specific embodiment, three force-applying members 102 are arranged horizontally. The force-applying component 102 uses a hydraulic cylinder. The side plate positioning assembly 1 also includes a support plate 12, which is movably mounted on the base plate 2. The upper end of the support plate 12 can abut against the side plate 11 of the bucket to be welded. The support plate 12 is used to support the side plate 11 of the bucket to be welded. By using the hydraulic cylinder, the position of the clamping force can be flexibly changed according to the thickness of the side plate 11 of the bucket to be welded. The arc plate support assembly 7 includes a connecting frame 713, which is mounted on the base plate 2 and located between the two side plate positioning assemblies 1. The connecting frame 713 and the arc plate support assembly 7 are connected to the side plate positioning assembly 1. The base plate 2 is welded together. A support plate 704 is detachably connected to the connecting frame 713. The support plate 704 has a shape similar to the cross-sectional shape of the bucket. The support plate 704 has a triangular structure and an arc-shaped top. One side of the support plate 704 is a sloping edge used to support the bucket teeth 6 to be welded, and the other side is a vertical edge used to support the bucket ear plate 4 to be welded. The support plate 704 is used to support the arc-shaped plate 3 of the bucket to be welded. A support member 10 is also provided on the support plate 704 to support the bucket teeth 6 to be welded and prevent them from being welded. When the bucket teeth 6 are welded down, and the shape and size of the bucket teeth 6 and the arc plate 3 of the bucket to be welded change, the two support plates 704 can be replaced. The ear plate positioning assembly 5 includes a support base 502, which is detachably connected to the base plate 2 by bolts and is located on one side of the connecting frame 713. A positioning shaft 501 is detachably installed on the support base 502. The positioning shaft 501 can pass through the ear plate 4 of the bucket to be welded and the support base 502. When the structure of the ear plate 4 of the bucket to be welded changes, the matching ear plate positioning assembly 5 can be replaced.

[0033] This specific embodiment allows for the detachable connection of the support plate 704 and the support base 502. After the size and structure of the bucket arc plate 3, the bucket ear plate 4, and the bucket teeth 6 to be welded change, the matching support plate 704 and support base 502 can be replaced without replacing all the tooling. This achieves universality for the bottom plate 2 and the side plate positioning assembly 1. Only a variety of support plates 704 and support bases 502 need to be equipped as needed, reducing tooling storage and management costs.

[0034] like Figure 3 , Figure 4 and Figure 6As shown, to ensure support for the support plate 12, in this specific embodiment, a guide member 8 is provided between each support base 502 and the connecting frame 713. The guide member 8 has a guide groove 801, and the support plate 12 moves up and down along the guide groove 801. An adjusting block 13 is slidably provided at the bottom of the guide member 8, and the adjusting block 13 can slide in the horizontal plane. The upper surface of the adjusting block 13 can abut against the lower end of the support plate 12. Specifically, four guide members 8 are provided between each support base 502 and the connecting frame 713, arranged in pairs. The two guide members 8 in each pair are close to each other and share a longer adjusting block 13. The adjusting block 13 has a rectangular block structure. The bottom of the guide 8 is provided with a groove, and the adjusting block 13 can slide in the groove. The guide 8 is made of two opposing steel plates with a gap between them to form a guide groove 801. The lower part of the steel plate is welded to the bottom plate 2. A positioning pin 14 passes through the adjusting block 13, and a corresponding pin hole is provided on the bottom plate 2 to prevent the adjusting block 13 from being misaligned and failing to provide reliable support for the support plate 12, thus affecting the positioning accuracy. When the size of the bucket side plate 11 to be welded changes, the adjusting block 13 of the corresponding height is replaced, thereby adjusting the height of the support plate 12 without replacing the adjusting plate.

[0035] like Figures 3 to 5As shown, in this specific embodiment, the connecting frame 713 includes two connecting plates 701 arranged opposite each other, and a reinforcing plate 703 is provided between the two connecting plates 701. The lower ends of both the connecting plates 701 and the reinforcing plate 703 are welded to the base plate 2. A support plate 704 is provided on the outer side of the connecting plates 701, and at least two threaded sleeves 702 are welded to the inner side of the connecting plates 701. In this specific embodiment, three threaded sleeves 702 are provided, and the three threaded sleeves 702 are connected by a reinforcing rod. The reinforcing rod is welded to the connecting plate 701. A corresponding number of connecting bolts 714 are horizontally passed through the support plate 704, and the connecting bolts 714 are connected to the threaded sleeves 702 after passing through the support plate 704. Since this fixture is a welded structure, the error is relatively large. To avoid To address the issue of misalignment of the connecting bolts 714, the support plate 704 has a first connecting hole 705 on its upper part, through which the corresponding connecting bolt 714 passes. The support plate 704 also has a second connecting hole 706 and a third connecting hole 707, each through which a corresponding connecting bolt 714 passes. All three connecting holes (705, 706, and 707) are loop-shaped holes, allowing adjustment of the connecting bolts 714 to ensure connection. However, because the loop-shaped holes cannot accurately define the position of the connecting bolts 714, the support plate 704 tends to shift in the vertical plane, affecting the accuracy of the support position. To avoid this problem... In this specific embodiment, a positioning rib 715 is horizontally welded onto the base plate 2, extending in the left-right direction. A positioning groove 710 is provided at the lower part of the support plate 704, into which the positioning rib 715 can extend. A clearance groove 709 is also provided at the lower part of the support plate 704, used to avoid the guide member 8 at the corresponding position. Connecting hole one 705 and connecting hole two 706 communicate with the corresponding clearance groove 709. By setting the positioning rib 715, the support plate 704 is effectively prevented from moving back and forth, improving the accuracy of positioning the arc plate 3 of the bucket to be welded. Furthermore, since the force between the bucket and the support plate 704 is large after welding, and the connecting holes one to three are all connected to the connecting bolts 714, There is a large gap between the support plate 704 and the bucket. When the bucket is removed from the tooling, it is easy to lift the support plate 704, which may cause a safety accident. Therefore, the support plate 704 is horizontal on the outside and is equipped with limit bolt 1 711 and limit bolt 2 708. Limit bolt 1 711 is opposite to connection hole 2 706, and limit bolt 2 708 is opposite to connection hole 3 707. Limit bolt 1 711 and limit bolt 2 708 are located below the corresponding connecting bolt 714. Limit bolt 1 711 and limit bolt 2 708 can abut against the corresponding connecting bolt 714 under the action of external force. Specifically, four end ears are welded on the outside of the support plate 704. The end ears are provided with internal threaded holes. Limit bolt 1 711 or limit bolt 2 708 passes through each pair of end ears.With this configuration, when the welded bucket is hoisted upwards, the support plate 704 cannot move relative to the connecting bolt 714 due to the action of the first limiting bolt 711 and the second limiting bolt 708. This ensures that the connection with the connecting frame 713 remains constant and will not detach.

[0036] like Figure 5 As shown, to ensure the arc-shaped support assembly can stably support the arc-shaped plates 3 of various sizes of buckets to be welded, in this specific embodiment, an adjusting pad 712 is provided between the support plate 704 and the connecting plate 701. The two ends of the adjusting pad 712 abut against the connecting plate 701 and the support plate 704 respectively. To facilitate installation, the adjusting pad 712 has a columnar structure and an installation groove. The adjusting pad 712 is secured to the connecting bolt 714 through the installation groove. With this configuration, when the size of the arc-shaped plate 3 of the bucket to be welded changes, only the adjusting pad 712 of the corresponding axial length needs to be replaced, without needing to replace the connecting frame 713. This allows for accurate adjustment of the position between the support plate 704 and the connecting plate 701. Regardless of the size change of the arc-shaped plate 3 of the bucket to be welded, the support plate 704 can be supported near the edge of the arc-shaped plate 3 of the bucket to be welded, ensuring symmetrical support and improving support stability.

[0037] like Figure 4 As shown, in this specific embodiment, the support member 10 is a block structure, and an adjusting bolt 9 passes through the support member 10. The end of the adjusting bolt 9 can abut against the bucket teeth 6 to be welded. By setting the adjusting bolt 9, the position of the tooling supporting the bucket teeth 6 to be welded can be adjusted to adapt to the size changes of the bucket teeth 6 to be welded, and to compensate for manufacturing errors, so as to ensure the accuracy of the positioning of the bucket teeth 6 to be welded.

[0038] The working process of this tooling is as follows: First, select appropriate support plate 704, ear plate positioning assembly 5, adjusting block 13, and adjusting shim 712 according to the bucket to be welded; then connect support plate 704 to connecting plate 701. During connection, snap support plate 704 with positioning rib 715, and screw in three connecting bolts 714 until adjusting shim 712 is squeezed tight by support plate 704 and connecting plate 701. Install limit bolt one 711 and limit bolt two 708 on both sides; insert appropriate adjusting block 13 into the sliding groove at the bottom of guide member 8 and move it to the appropriate position, with support plate 12 supported on adjusting block 13; first, place the arc plate 3 of bucket to be welded on support plate 704, so that the support... Align the end face of the support plate 704 with the end face of the arc plate 3 of the bucket to be welded; place the side plate 11 of the bucket to be welded on the support plate 12 and hold it by hand, extend the piston rod of the force-applying component 102 and move it closer to the side plate 11 of the bucket to be welded until it abuts; place the bucket teeth 6 of the bucket to be welded on the bearing block, and make contact with the inclined edge of one side of the support plate 704; rotate the adjusting bolt 9 and observe the contact between the bucket teeth 6 of the bucket to be welded and the edge of the arc plate 3 of the bucket to be welded, so that there is no gap; install the support seat 502 with bolts, and install the ear plate 4 of the bucket to be welded using the positioning shaft 501, and make contact with the vertical edge of the other side of the support plate 704.

[0039] As can be seen from the above specific embodiments, this utility model has the following beneficial effects: 1. By disassembling and connecting the support plate 704 and the support base 502, the support plate 704 and the support base 502 can be replaced with matching ones after the size and structure of the bucket arc plate 3, the bucket ear plate 4, and the bucket teeth 6 to be welded change. It is not necessary to replace all the tooling, which realizes the universality of the bottom plate 2 and the side plate positioning assembly 1. Only the support plate 704 and the support base 502 need to be equipped according to production needs, which reduces the tooling storage and management costs. 2. By setting guide components 8, the smooth movement of the support plate 12 is ensured, and by using adjustment blocks 13 of different heights, the stability of the support plate 12 after the position is changed is ensured, so that it will not slip off under the pressure of the bucket side plate 11 to be welded. 3. By using the gourd hole as the through hole for the connecting bolt 714, the manufacturing error of this tooling can be compensated, and the connecting bolt 714 can be prevented from being unable to connect with the threaded sleeve 702 on the connecting plate 701 due to manufacturing error. 4. By setting the positioning rib 715, the front and rear positions of the support plate 704 on the base plate 2 can be accurately limited, and it can accurately match the arc plate 3 of the bucket to be welded, thus solving the problem of low precision caused by the gap generated by the use of the gourd hole. 5. By setting the adjustment pad 712, the left and right distance of the arc plate support assembly 7 can be adjusted to match the arc plate 3 of the bucket to be welded, and to ensure that the two support plates 704 are always symmetrically arranged on both sides of the connecting frame 713, thereby improving the stability of the support. 6. By setting limit bolt 1 711, limit bolt 2 708 and limit bolt 3, relative movement between support plate 704 and connecting bolt 714 under external force can be prevented. 7. By setting the adjusting bolt 9, the position of the bucket teeth 6 to be welded can be adjusted to adapt to the size changes of the bucket teeth 6 to be welded, and can make up for manufacturing errors and ensure the accuracy of the positioning of the bucket teeth 6 to be welded.
