[0001] The utility model relates to the technical field of grab bucket machinery manufacturing, in particular to a grab bucket team tooling. Background Art

[0002] As is known, grabs are generally used in docks, power plants, steel plants and other industries to grab bulk cargo. The most common grab is a six-petal grab, in which the upper and lower beam frames are important components of the grab. These two components generally include a circular ring plate, an inner rib plate and six outer ear plate assemblies, in which the mounting holes of the six outer ear plate assemblies must be on the same diameter circle and divided into six equal parts. Traditionally, a simple bracket is used for marking and assembly, and then the whole is bored and the end surface is scraped after welding. However, this method is difficult to assemble and has low efficiency.

[0003] A Chinese utility model patent with announcement number CN214237087U discloses a special tooling for manufacturing and processing a six-petal grab bucket bolster. Through the relative rotation of the upper seat plate and the lower seat plate and with the help of the setting of scale lines and reference lines, the workpieces to be processed can be quickly and accurately matched with the workpieces to be welded on the support column. After one group of workpieces is positioned, the other 5 groups of workpieces to be welded can be spliced ​​into place only by rotation. However, the defects of the existing patent are that the equal division accuracy of the welding of multiple ear plates is not high, the welding positioning is not stable enough, and it cannot meet the welding needs of bolsters of different diameters. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology and solve the existing technical problems, the utility model discloses a grab team tooling, which can not only effectively improve the welding accuracy of the ear plate, but also be suitable for welding upper and lower beam frame workpieces of different specifications.

[0005] In order to achieve the above utility model purpose, the utility model adopts the following technical solutions:

[0006] A grab team tooling comprises a base plate, an ear seat, a locating pin and a tooling shaft, wherein the upper plate surface of the base plate is evenly spaced with a plurality of inverted T-shaped grooves, the inner ends of the inverted T-shaped grooves correspond to the middle of the base plate, and the outer ends pass through to the edge of the base plate, and the bottom surface of the inverted T-shaped groove is evenly spaced with a plurality of locating holes arranged along its penetration direction, and the centers of the locating holes at the same arrangement positions of each inverted T-shaped groove are on the same virtual circle line; the top of the ear seat is provided with a hinged through hole adapted for inserting the tooling shaft, and the bottom of the ear seat is provided with a slide block adapted to be clamped in the inverted T-shaped groove and capable of sliding along the inverted T-shaped groove at a position corresponding to the transverse symmetric surface of the hinged through hole, one end of the slide block is fixed to the bottom surface of the ear seat, and the other end of the slide block is provided with a socket capable of inserting the locating pin into the corresponding locating hole for positioning.

[0007] Furthermore, the ear seat includes a horizontal base plate and vertical plates symmetrically fixed on both sides of the upper plate surface of the horizontal base plate, and the top of the plate surface of each vertical plate is provided with a hinged hole, and the hinged through hole is set as a virtual hole, and the two hinged holes correspond to the two ends of the virtual hole.

[0008] Furthermore, the number of the inverted T-shaped grooves is set to six.

[0009] Furthermore, the bottom plate is configured as a square plate, and a central hole is provided in the center of the bottom plate.

[0010] Furthermore, the lower surface of the bottom plate is provided with supporting ribs.

[0011] Furthermore, a lower portion of one end of the slide block is axially extended outward to form an extension portion, and the insertion hole is arranged on the extension portion.

[0012] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0013] The grab bucket assembly tooling disclosed by the utility model divides the base plate into equal parts in advance by evenly opening a plurality of inverted T-grooves on the base plate, so that the sliding block connected to the ear seat can be accurately positioned no matter which inverted T-groove it is mounted in. After the ear plate to be welded is firmly inserted into the ear seat by the tooling shaft, it can be welded to the circular ring plate placed in the middle of the base plate, thereby avoiding the influence of welding deformation on welding accuracy and improving the welding effect. More importantly, after the ear seat is welded at one position, it can be disassembled and assembled for welding at the next position, thereby achieving the effect of saving cost by using one ear seat. In addition, the ear seat can also be used for welding upper and lower beam frame workpieces of different specifications by adjusting the position in the inverted T-groove, thereby greatly improving the applicability of the tooling.

[0023] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction:

[0024] Combined with Figure 1-8 The grab team tooling includes a base plate 1, an ear seat 3, a positioning pin 7 and a tooling shaft 6. According to needs, the base plate 1 is set as a square plate for easy movement and positioning. A central hole 103 is provided in the center of the base plate 1 to reduce weight and facilitate positioning and processing of the inverted T-shaped groove 101; in addition, a supporting rib 2 is provided on the lower surface of the base plate 1 to ensure stable support. When in use, the lower end of the positioning hole 102 is exposed, which can facilitate the disassembly and assembly of the positioning pin 7; a plurality of inverted T-shaped grooves 101 are evenly spaced on the upper surface of the base plate 1. When the manufacturing grab is a commonly used six-petal grab, the inverted T-shaped grooves 10 1 can also be set to six. The inner end of the inverted T-shaped slot 101 corresponds to the middle of the bottom plate 1, and the outer end passes through to the edge of the bottom plate 1. Generally, the assembly parts will slide in from the outer end of the inverted T-shaped slot 101. The bottom surface of the inverted T-shaped slot 101 is evenly spaced along its penetration direction and is provided with a plurality of positioning holes 102. The larger the number and spacing of the positioning holes 102, the more diameter specifications of the grab beam bearing parts can be assembled and welded. The centers of the positioning holes 102 at the same arrangement position of each inverted T-shaped slot 101 are on the same virtual circle line, ensuring that the ear seat 3 can be positioned on the same diameter circle when assembled;

[0025] The top of the ear seat 3 is provided with a hinged through hole 5 for inserting the tooling shaft 6. When the ear seat 3 is a whole solid part, the hinged through hole 5 is a real hole that passes through the ear seat 3. Of course, it is also possible to set the ear seat 3 to include a horizontal base plate 301 and vertical plates 302 symmetrically fixed on both sides of the upper plate surface of the horizontal base plate 301 according to needs. The top of the plate surface of each vertical plate 302 is provided with a hinged hole 303, and the hinged through hole 5 is set as a virtual hole. The two hinged holes 303 correspond to the two ends of the virtual hole. The positioning effect of the hinged through hole 5 is achieved by the two hinged holes 303, which ensures that the structure is stable and lighter, and saves materials; the bottom of the ear seat 3 corresponds to the hinged through hole 5 horizontally A slide block 4 is provided at the position of the symmetrical surface, which is adapted to be clamped in the inverted T-slot 101 and can slide along the inverted T-slot 101. One end of the slide block 4 is fixed to the bottom surface of the ear seat 3, and the other end of the slide block 4 is provided with a socket 401 that can correspond to the positioning hole 102 to insert the positioning pin 7 for positioning. The ear seat 3 can be adjusted to move and position by moving the slide block 4 in the inverted T-slot 101. According to needs, the lower part of one end of the slide block 4 is axially extended to form an extension part, and the socket 401 is provided on the extension part. By extending the part of the slide block 4, while facilitating the insertion of the positioning pin 7 for positioning, the sliding fit accuracy with the inverted T-slot 101 can be improved.

[0026] To implement the grab bucket assembly tooling described in the utility model, it is necessary to first place the circular ring plate with ribs of the grab bucket beam frame in the middle of the upper plate surface of the bottom plate 1 for positioning, and if necessary, add a pad or support at the bottom for height adjustment and leveling; when only one ear seat 3 is used, first slide the slider block 4 of the ear seat 3 into the inverted T-slot 101 according to design requirements, and move it to the corresponding positioning hole 102 position, insert the positioning pin 7 into the corresponding positioning hole 102 and the socket 401 for positioning, fix the ear seat 3 and install it, and then select a pair of ear plates and assemble them to the ear seat 3, the ear holes on the ear plate are the same size as the hinged through holes 5, and then the tooling shaft 6 is passed through for positioning and fixing, and then the ear plate and the annular plate and other adjacent workpiece welds are spot welded. During spot welding, it is necessary to rotate the tooling shaft 6 while welding to prevent it from being difficult to remove due to heat. After spot welding one ear plate, the ear seat 3 is removed and transferred to other inverted T-slots 101 at the same position until all the ear plates are welded; of course, if the number of ear seats 3 corresponding to the number of ear plates is used, they can also be installed in advance without changing the position of the ear seat 3.
