A retaining plate 602, the retaining plate 602 comprising: a fixed bottom plate 6021 attached to the second end of the sleeve 601, the fixed bottom plate 6021 configured to fix the second workpiece 640; a boss 6022 located on a first side of the fixed base plate 6021, a sidewall of the boss 6022 configured to mate with the opening; a pad slot (not labeled) located on a second side of the fixed floor 6021; a bottom plate hole (not shown) axially extends through the fixed plate 602 for the first workpiece 630 to pass through. A pad 603 located in the pad slot, the pad 603 having a pad hole therein for the first workpiece 630 to pass through.
The first end of the sleeve 601 is fixedly connected with the bed shell 500, and the second workpiece 640 is fixed on the fixed bottom plate 6021, so that the sleeve 601 cannot rotate in the friction welding process, and the second workpiece 640 can be stably supported.
In this embodiment, the fixed end 6011 of the sleeve 601 has sleeve through holes arranged along the circumferential direction; the lathe bed shell 500 is provided with a threaded hole corresponding to the sleeve through hole; the forge welding formula friction weld frock includes: and the bolt penetrates through the sleeve through hole and is in threaded fit with the threaded hole.
In this embodiment, the sleeve 601 is fixedly connected to the fixed bottom plate 6021. Specifically, the sleeve 601 has a threaded hole therein, and the fixed bottom plate 6021 has a bottom plate through hole thereon; the friction welding frock still includes: and the bolt penetrates through the through hole of the bottom plate and is fixedly connected with the threaded hole.
In the friction welding process, the cylinder of the first workpiece 630 penetrates through the bottom plate hole and the pad hole (the through hole of the first clamp body in the axial direction comprises the bottom plate hole and the pad hole), and one end of the cylinder, which is far away from the disk body, is clamped by the spring sleeve of the axial clamping assembly.
In this embodiment, the bottom plate hole has an internal thread; the formula friction welding frock of forging a drawing still includes: the outer side wall of the first end of the adjusting sleeve 604 is provided with an external thread, the external thread of the adjusting sleeve is in threaded fit with the internal thread of the bottom plate hole, the adjusting sleeve 604 is provided with an inner hole penetrating along the axial direction, and the inner hole of the adjusting sleeve 604 is larger than the outer diameter of the first workpiece 630.
The adjusting sleeve 604 is located between the fixing plate 602 and the first workpiece 630, and prevents the cylinder of the first workpiece 630 from contacting the fixing plate 602, so that the size of the inner hole of the fixing plate 602 is not enlarged by wear during the friction welding process of the bottom plate hole of the fixing plate 602. In addition, the size of the inner hole of the adjusting sleeve 604 is larger than the size of the outer diameter of the first workpiece 630, so that the inner hole of the adjusting sleeve 604 is in clearance fit with the first workpiece 630, and in the friction welding process, the side wall of the first workpiece 630 does not rub with the inner hole of the adjusting sleeve 604, which is beneficial to improving the appearance quality of the cylinder in the first workpiece 630.
In this embodiment, the outer sidewall of the second end of the adjusting sleeve 604 includes: and the screwing hole 6041 penetrates through the side wall of the adjusting sleeve, and the screwing hole 6041 is used for penetrating through the force application rod to perform spiral matching on the adjusting sleeve 604 and the internal thread in the bottom plate hole.
It should be noted that the screwing hole 6041 of the adjusting sleeve 604 extends out of the opening, which is beneficial for the screwing hole 6041 to penetrate through the force applying rod to enable the external thread of the adjusting sleeve and the internal thread of the bottom plate hole to perform thread rotation.
It should be noted that the size of the outer side wall of the second end of the adjusting sleeve 604 is smaller than the size of the major diameter of the external thread of the first end of the adjusting sleeve, so that the second end of the adjusting sleeve does not interfere with the internal thread of the bottom plate hole.
In other embodiments, the stretch-forging type friction welding tool may further have no adjusting sleeve, and the pad hole is in clearance fit with the side wall of the first workpiece, so that the side wall of the first workpiece does not rub against the pad hole while the first workpiece rotates in the pad hole, which is beneficial to improving the appearance quality of the cylinder in the first workpiece. The pad hole and the bottom plate hole are used for limiting the degree of freedom of the first workpiece in the radial direction, so that the first workpiece is not prone to radial jumping in the friction welding process.
Specifically, the pad hole and the bottom plate hole are coaxial, so that the first workpiece 630 penetrating through the pad hole and the bottom plate hole is not prone to radial force at each position in the axial direction, and after friction welding, the first workpiece 630 is not prone to bending.
Although the embodiments of the present specification are disclosed above, the embodiments of the present specification are not limited thereto. Various changes and modifications may be effected by one skilled in the art without departing from the spirit and scope of the embodiments herein described, and it is intended that the scope of the embodiments herein described be limited only by the scope of the appended claims.
