Description

Technical Field

[0001] The embodiments of this utility model relate to the field of bucket processing technology, specifically to a bucket positioning device. Background Technology

[0002] Excavators, as a common type of construction machinery, are widely used in various excavation, loading, and other operational scenarios. The bucket, as the core component of the excavator that directly interacts with materials, directly affects the excavator's working efficiency, digging capacity, and operational quality.

[0003] Riveting is one of the many processes in excavator bucket manufacturing. During riveting, the various components of the excavator bucket need to be positioned and fixed together to form an integral structure. Traditional excavator bucket riveting methods mainly rely on manual positioning operations, placing the various components of the excavator bucket in predetermined positions, and then riveting or welding them together.

[0004] Manual positioning has lower accuracy. Due to individual differences among operators and the limitations of visual observation, it is difficult to guarantee high accuracy every time. Such positioning deviations can easily lead to problems such as insufficient dimensional accuracy and deformation in the assembled bucket, reducing the bucket's strength and rigidity, and affecting its service life and working performance.

[0005] Therefore, developing a bucket positioning device that can improve bucket positioning accuracy and reduce bucket deformation has become an important problem that urgently needs to be solved in the current bucket manufacturing field. It is of key significance for improving the quality of bucket manufacturing and promoting the development of the engineering construction industry. Utility Model Content

[0006] To overcome the above-mentioned defects, embodiments of this utility model provide a bucket positioning device, which solves the technical problem of insufficient positioning accuracy of manually positioned buckets in related technologies.

[0007] According to one aspect, at least one embodiment of the present invention provides a bucket positioning device, including a base, an inner mold support plate and an outer mold assembly, wherein the inner mold support plate is disposed on the base, and the shape of the top of the inner mold support plate is configured to match the shape of the inner wall of the bucket plate for supporting the inner wall of the bucket plate. The outer mold assembly includes a tailstock, a middle chain rod, and a front positioning rod. One end of the tailstock is hinged to the base, and the other end is hinged to one end of the middle chain rod. The other end of the middle chain rod is hinged to the middle of the front positioning rod. The outer mold assembly further includes a first telescopic member, a second telescopic member, and a third telescopic member. The first telescopic member is hinged at both ends to the base and the tailstock, the second telescopic member is hinged at both ends to the tailstock and the central chain rod, and the third telescopic member is hinged at both ends to the base and one end of the front positioning rod. The other end of the front positioning rod is used to abut against the outer wall of the bucket plate. The tailstock and the central chain rod are configured to match the shape of the outer wall of the bucket plate near the inner mold support plate, and are used to press the outer wall of the bucket plate.

[0008] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: There are two inner mold support plates, and a horizontal bar connects the two inner mold support plates. There are two sets of horizontal bars, one above the other, and a vertical bar connects the two sets of horizontal bars.

[0009] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: Both inner mold support plates are equipped with lever arms, the middle of which is hinged to the inner mold support plate, and a pressure plate is hinged to the top of the lever arm. The pressure plate is used to position the bucket side plate.

[0010] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: The bottom end of the lever arm is hinged to the bottom end of the connecting rod, and a spindle is installed at the top end of the connecting rod. The vertical rod has a vertical groove, and the spindle is slidably disposed in the groove. It also includes a fourth telescopic member with both ends hinged to the spindle and the base respectively. The fourth telescopic member can drive the lever arm to swing by means of the connecting rod.

[0011] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: The pressure plate is threaded with several bolts, which are used to contact the side plate of the bucket.

[0012] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: The outer side of the inner mold support plate is provided with several positioning plates for abutting against the side plate of the excavator bucket.

[0013] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: Both sides of the inner mold support plate have support parts for supporting the edge of the bucket plate opening.

[0014] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: The inner mold support plate has positioning holes, the positions of which correspond to the positions of the process holes reserved on the bucket side plate, so that the positioning pin can be inserted into the process holes and the positioning holes at the same time to position the bucket side plate.

[0015] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: The base is provided with a auger support plate, and the top of the auger support plate has a support groove for supporting the auger on the bucket for connection with the boom.

[0016] For example, the bucket positioning device provided in at least one embodiment of this utility model further includes: Both the tailstock and the middle link have reserved slots for accommodating the reinforcing plates on the bucket plate.

[0017] The beneficial effects of the embodiments of this utility model are as follows: In this invention, when using the bucket positioning device, the three telescopic components are first controlled to relax the tailstock, middle chain rod, and front positioning rod, providing space for placing the bucket plate. The bucket plate is then placed between the inner mold support plate and the outer mold assembly, so that the inner wall of the bucket plate contacts the top of the inner mold support plate. Then, the three telescopic components are controlled again: the first component pushes the tailstock to rotate around its hinge point with the base; the second component pushes the middle chain rod to rotate around its hinge point with the tailstock; and the third component pushes the front positioning rod to rotate around its hinge point with the middle chain plate, causing the tailstock, middle chain rod, and front positioning rod to approach and press against the outer wall of the bucket plate. Because the top shape of the inner mold support plate matches the inner wall of the bucket plate, the tailstock and middle chain rod of the outer mold assembly match the outer wall of the bucket plate near the edge of the inner mold support plate, and the end of the front positioning rod abuts against the bucket plate, the bucket plate is ultimately positioned in the predetermined position under the combined action of the inner and outer molds, so that the bucket plate is forced to fit the shape of the top of the inner mold support plate, thereby eliminating assembly gaps. This makes the fit between the various parts more precise when assembling other components in the later stage, and reduces the deformation of the bucket body caused by improper assembly.

[0018] The inner mold support plate matches the inner wall shape of the bucket plate, and the outer mold assembly matches the outer wall shape of the bucket plate. By controlling the telescopic components, the bucket plate is precisely positioned, eliminating the error of manual positioning, improving the positioning accuracy of the bucket plate, ensuring that the bucket has accurate dimensional accuracy after assembly, and guaranteeing the stability and reliability of the bucket during operation.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0023] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0027] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-6As shown, this invention illustrates a bucket positioning device according to one embodiment of the present invention, comprising a base 1, an inner mold support plate 2, and an outer mold assembly 3. The base 1 is the basic support structure of the entire positioning device. The inner mold support plate 2 is mounted on the base 1, and its top shape matches the shape of the inner wall of the bucket plate. In the outer mold assembly 3, one end of the tailstock 301 is hinged to the base 1, and the other end is hinged to one end of the central chain rod 302. The other end of the central chain rod 302 is hinged to the middle of the front positioning rod 303. This hinged structure allows relative movement between the tailstock 301, the central chain rod 302, and the front positioning rod 303. The shapes of the edges of the tailstock 301 and the central chain rod 302 near the inner mold support plate 2 match the shape of the outer wall of the bucket plate, allowing them to fit tightly against the outer wall of the bucket plate.

[0029] The first telescopic component 304 is hinged at both ends to the base 1 and the tailstock 301, respectively. The second telescopic component 305 is hinged at both ends to the tailstock 301 and the central link 302, respectively. The third telescopic component 306 is hinged at both ends to the base 1 and one end of the front positioning rod 303, respectively. By controlling the telescopic length of the components, the position and angle of the tailstock 301, the central link 302, and the front positioning rod 303 can be adjusted, thereby enabling the clamping and loosening operations of the bucket plate.

[0030] Working Principle: When using the bucket positioning device, firstly, by controlling the three telescopic components, the tailstock 301, the central link 302, and the front positioning rod 303 are relaxed, providing space for placing the bucket plate. The bucket plate is placed between the inner mold support plate 2 and the outer mold assembly 3, so that the inner wall of the bucket plate contacts the top of the inner mold support plate 2. Then, the three telescopic components are controlled again. The first telescopic component 304 pushes the tailstock 301 to rotate around its hinge point with the base 1, the second telescopic component 305 pushes the central link 302 to rotate around its hinge point with the tailstock 301, and the third telescopic component 306 pushes the front positioning rod 303 to rotate around its hinge point with the central link plate, so that the tailstock 301, the central link 302, and the front positioning rod 303 approach and press against the outer wall of the bucket plate. Because the top shape of the inner mold support plate 2 matches the inner wall of the bucket plate, the tailstock 301 and the middle chain rod 302 of the outer mold assembly 3 match the outer wall of the bucket plate near the edge of the inner mold support plate 2, and the end of the front positioning rod 303 abuts against the bucket plate, the bucket plate is finally positioned in the predetermined position under the combined action of the inner and outer molds, so that the bucket plate is forced to fit the shape of the top of the inner mold support plate 2, thereby eliminating the assembly gap. This makes the fit between the various parts more precise when assembling other parts in the future, and reduces the deformation of the bucket body caused by improper assembly.

[0031] The inner mold support plate 2 matches the shape of the inner wall of the bucket plate, and the outer mold assembly 3 matches the shape of the outer wall of the bucket plate. By controlling the telescopic components, the bucket plate is accurately positioned, eliminating the error of manual positioning, improving the positioning accuracy of the bucket plate, ensuring that the bucket has accurate dimensional accuracy after assembly, and guaranteeing the stability and reliability of the bucket during operation.

[0032] In some examples, such as Figure 4 , 6 As shown, there are two inner mold support plates 2, connected by a horizontal bar 4. The horizontal bars 4 are arranged in two sets, upper and lower, and connected by a vertical bar 5. A lever arm 6 is installed on each of the two inner mold support plates 2. The middle of the lever arm 6 is hinged to the inner mold support plate 2, allowing it to swing around the hinge point. A pressure plate 7 is hinged to the top of the lever arm 6, contacting the bucket side plate. The swinging of the lever arm 6 achieves the pressing and positioning of the bucket side plate. The bottom end of the lever arm 6 is hinged to the bottom end of the connecting rod 8. A spindle 9 is installed at the top of the connecting rod 8. A vertical groove 10 is machined on the vertical bar 5, allowing the spindle 9 to slide within the groove 10. The two ends of the fourth telescopic member 11 are hinged to the spindle 9 and the base 1, respectively. The pressure plate 7 has several threaded holes, each with a bolt 12 threadedly connected to it, the end of which can contact the bucket side plate.

[0033] Working Principle: The horizontal bar 4 and vertical bar 5 together form a frame structure, providing additional support for the two inner mold support plates 2, enhancing the structural strength of the inner mold support plates 2, enabling them to withstand pressure and resist deformation when supporting the inner wall of the bucket plate. When positioning the bucket side plate, the fourth telescopic component 11 is activated, causing the mandrel 9, which is hinged to it, to slide up and down within the groove 10 of the vertical bar 5. Since the mandrel 9 is connected to the connecting rod 8, the connecting rod 8 swings with the movement of the mandrel 9. The bottom end of the lever arm 6 is hinged to the connecting rod 8, so the swing of the connecting rod 8 causes the lever arm 6 to swing around its central hinge point. The pressure plate 7 at the top of the lever arm 6 moves closer to the bucket side plate as the lever arm 6 swings, pressing the side plate against the side of the bucket plate, thus achieving the positioning of the bucket side plate and ensuring the assembly accuracy between the bucket side plate and the bucket plate. Since other components may need to be assembled on the bucket side plate, its surface may not be completely flat. Operators can adjust the distance between the end of bolt 12 and the bucket side plate by rotating bolt 12 to adapt to different surface shapes and positioning requirements of the bucket side plate.

[0034] In some examples, such as Figure 6 As shown, several positioning plates 13 are distributed on the outer side of the inner mold support plate 2, which can abut against the bucket side plate to determine the position of the side plate in the lateral direction. Support parts 14 are respectively provided on both sides of the inner mold support plate 2. The shape of the support parts 14 matches the shape of the bucket plate edge, effectively supporting the edge of the bucket plate opening. Positioning holes 15 are machined on the inner mold support plate 2 at the positions corresponding to the pre-reserved process holes 16 on the bucket side plate. The process holes 16 and positioning holes 15 are used for inserting positioning pins. A auger support plate 17 is provided on the base 1. A support groove 1701 is machined on the top of the auger support plate 17, and the shape of the support groove 1701 matches the outer contour of the auger. Pre-reserved grooves 18 are machined on the tailstock 301 and the middle chain rod 302, corresponding to the position and shape of the reinforcing plate on the bucket plate.

[0035] Working principle: The positioning plate 13, by abutting against the side plate of the bucket, restricts the movement of the side plate in the lateral direction, providing a positioning reference for the side plate in the lateral direction and reducing lateral deviation of the side plate during assembly. The support part 14 supports the edge of the bucket plate opening, increasing the contact point and support area with the bucket plate, reducing positional offset caused by the weight of the bucket plate itself or other external forces, and improving the positioning accuracy of the entire bucket. When the bucket side plate is placed on the inner mold support plate 2 and the position is initially adjusted, the positioning pin is simultaneously inserted into the process hole 16 and the positioning hole 15, playing a dual role of positioning and fixing, restricting the rotation and displacement of the side plate in the plane, and improving the positional accuracy of the side plate. During the bucket positioning process, the auger is placed in the support groove 1701, which provides stable support for the auger, ensuring the correct position during bucket assembly. During bucket assembly, the reinforcing plate can be directly placed into the reserved groove 18, which restricts the movement of the reinforcing plate in all directions, ensuring the relative positional accuracy between the reinforcing plate and the bucket plate. This not only facilitates the installation of the reinforcing plate, but also ensures the correct position of the reinforcing plate in the bucket structure.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
