[0001] This utility model relates to a combination tooling, specifically a combination tooling for quick positioning and alignment of joint forgings, belonging to the field of joint forging processing. Background Technology
[0002] Forgings are widely used in parts manufacturing. Joints, as a typical forging, are commonly used in hydraulic systems in aviation, automotive, and marine industries. However, due to the presence of die-formed edges and irregular shapes, forgings are difficult to clamp and align during machining, hindering rapid processing. Conventional methods using screws, bolts, and clamping plates are employed, but these methods involve lengthy preparation times, inconvenient tooling assembly and disassembly, and significantly increased labor and material costs. Utility Model Content
[0003] To address the problems in the existing technology, this utility model provides a combined tooling for rapid positioning and alignment of joint forgings.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A combination tooling for quick positioning and alignment of joint forgings includes a base, a groove for placing the joint forging is provided on one side of the top of the base, and the base is formed by splicing two symmetrically arranged semi-shaped seats. The base is fitted inside the positioning jig, and an opening groove is opened through the side wall of the positioning jig.
[0006] Optionally, the base is cylindrical, the positioning tire is cylindrical, and a limiting boss is provided along the circumferential direction on the lower inner wall of the positioning tire. The bottom end of the base is placed on the limiting boss, and the base and the positioning tire are installed with a gap.
[0007] Optionally, the top of the positioning tire is connected with a positioning boss along the circumferential direction. The inner diameter of the positioning boss is the same as the inner diameter of the positioning tire, and the outer diameter is larger than the outer diameter of the positioning tire. The opening groove passes through the limiting boss and the positioning boss.
[0008] Optionally, the groove includes a horizontal groove and a vertical groove integrally connected to the horizontal groove. The horizontal groove is used to place the horizontal cylinder of the joint forging, and the vertical groove is used to place the vertical cylinder of the joint forging.
[0009] Optionally, the joint forging is placed inside the groove, and after the base and the positioning jig are concentrically assembled, the center of the vertical groove and the center of the vertical cylinder and the center of the positioning jig are on the same axis.
[0010] Optionally, the two semi-shaped seats are formed by cutting the base along the diameter direction, and the cutting line cuts the groove into two symmetrical parts, with the amount removed during the base cutting being 0.2 to 0.4 mm.
[0011] Optionally, both the base and the positioning tire are made of aluminum alloy, and the outer edges of both the base and the positioning tire are rounded.
[0012] The beneficial effects of this utility model are:
[0013] This modular tooling uses a forged joint piece to create a groove in the base, dividing the base in two. The amount of material removed from the middle of the half-base effectively ensures the amount of deformation under clamping force. A positioning jig is designed based on the base and machine tool chuck, with internal and external positioning and limiting bosses to ensure rapid positioning of the modular tooling. An opening groove on the outer wall of the positioning jig ensures sufficient deformation under clamping force and provides adequate clamping of the base. Furthermore, the centers of the base, the opening jig, and the forged joint piece are all on the same axis, adhering to the "centering" principle. The overall assembly ensures rapid tool setting during machining of the forged joint piece. This tooling is simple to operate, highly practical, and offers significant economic benefits.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Please see Figure 1-6 As shown, a combination tooling for quick positioning and alignment of joint forgings includes a base 2. The top side of the base 2 is provided with a groove for placing the joint forging 1. The base 2 is formed by splicing two symmetrically arranged semi-shaped seats 3. The base 2 is fitted inside the positioning jig 4. The side wall of the positioning jig 4 has an opening groove 43.
[0024] Specifically, the base 2 is cylindrical, and the positioning jig 4 is cylindrical. A ring of limiting bosses 41 is arranged along the circumferential direction on the lower inner wall of the positioning jig 4. The bottom end of the base 2 rests on the limiting bosses 41, and the base 2 and positioning jig 4 are installed with a gap. A ring of positioning bosses 42 is connected to the top of the positioning jig 4 along the circumferential direction. The inner diameter of the positioning bosses 42 is the same as the inner diameter of the positioning jig 4, and the outer diameter is larger than the outer diameter of the positioning jig 4. An opening groove 43 penetrates through the limiting bosses 41 and the positioning bosses 42. The cylindrical base 2 can be installed in conjunction with the cylindrical positioning jig 4. The ring-shaped limiting bosses 41 are used to support and limit the base 2 at the bottom, enabling quick positioning of the base 2. The top positioning bosses 42 facilitate engagement with the chuck on the machine tool, thus facilitating quick positioning and installation of the positioning bosses 42 with the machine tool. The opening groove 43 allows the opening groove 4 to deform when the machine tool applies clamping force to the positioning groove 4, increasing the clamping force on the base 2 and ensuring clamping stability.
[0025] Specifically, the groove includes a horizontal groove 21 and a vertical groove 22 integrally connected to the horizontal groove 21. The horizontal groove 21 is used to place the horizontal cylinder 11 of the connector forging 1, and the vertical groove 22 is used to place the vertical cylinder 12 of the connector forging 1. The shape and size of the groove are set according to the relevant shape and size of the connector forging 1, so that the connector forging 1 to be clamped and installed can be placed stably.
[0026] Specifically, the joint forging 1 is placed inside the groove, and after the base 2 and the positioning jig 4 are concentrically assembled, the center of the vertical groove 22, the center of the vertical cylinder 12, and the center 44 of the positioning jig 4 are on the same axis. The centers of multiple components in the combined tooling and the clamped joint forging 1 are all on the same axis, which is the "centering" principle, enabling rapid tool setting programming during subsequent machining of the joint forging 1.
[0027] Specifically, the two semi-shaped seats 3 are formed by cutting the base 2 along the diameter direction, and the cutting line cuts the groove into two symmetrical parts. The material removed during the cutting of the base 2 is 0.2-0.4 mm. The base 2 is cut by wire cutting, and the material removed is the sum of the diameter of the wire-cut molybdenum wire and the discharge gap. The presence of this material removal ensures that there is a gap after the two semi-shaped seats 3 are spliced, guaranteeing the clearance before clamping the joint forging 1. This allows the two semi-shaped seats 3 to move relative to each other under force, thus fully clamping the joint forging 1.
[0028] Specifically, both the base 2 and the positioning jig 4 are made of aluminum alloy, and the outer edges of both the base 2 and the positioning jig 4 are rounded. To ensure the dimensional stability of the tooling, both are made of hard aluminum alloy, which will not deform significantly under slight force, thus affecting normal use. The rounded corners also prevent workers from being scratched.
[0029] When positioning the joint forging 1 using this combined tooling, firstly, place the two semi-shaped seats 3 into the positioning jig 4; the bottom surfaces of the two semi-shaped seats 3 contact the limiting boss 41. Rotate the semi-shaped seats 3 clockwise inside the positioning jig 4 to test that the two are in a clearance fit, ensuring the reasonableness of the clearance fit. Place the joint forging 1 to be processed into the groove formed by the splicing of the two semi-shaped seats 3. Then, place the combined tooling into the machine tool chuck, ensuring that the positioning boss 42 contacts the end face of the chuck, achieving rapid positioning.
[0030] After being clamped by the machine tool, the locating jig 4 deforms, increasing the clamping force on the base 2 and ensuring clamping stability. A clearance is reserved between the two semi-shaped seats 3 before clamping, allowing them to shift relative to each other under force, thus fully clamping the joint forging 1. After clamping, the components on the joint forging 1 are concentric with the base 2 and the locating jig 4, adhering to the "centering" principle, enabling rapid tool setting programming during subsequent machining of the joint forging 1.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
