Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
It should be noted that welding positioning tooling fixture of the present utility model is applied to the positioning of welding workpiece, particularly Need ensure axiality, perpendicularity two or more workpiece welding, below using the first workpiece as flat part, first workpiece Upper setting circular hole;Second workpiece is thin_wall cylinder part, and second workpiece needs to be welded on the first workpiece, and when welding Exemplified by the axiality and perpendicularity that need guarantee second workpiece and the first workpiece circular hole, illustrate.Such as Fig. 1, the first workpiece 6 With second workpiece 7.
With reference to figure 1-4, the frock clamp includes:Connecting bolt 1, sleeve 2, jump ring 3, pressing plate 4 and attaching nut 5.Wherein, Jump ring 3 is arranged on sleeve 2 in the groove of excircle, and jump ring retraction makes sleeve outer through reducing during release, makes sleeve from the second work Come off in part, and because the setting of jump ring 3 makes sleeve 2 loose.Sleeve 2 serves as a contrast to be pressed in second workpiece inwall, pressing plate 6 On the end face of the free end of second workpiece.The circular hole of connecting bolt 1 from the first workpiece 6 penetrates the inwall of sleeve 2, and passes through pressing plate, It is threadedly coupled on top with attaching nut 5.
Connecting bolt 1, including bottom block 11, swelling inclined-plane 12 and connection screw thread 13.Wherein, bottom block 11 is straight Footpath is more than the diameter of the circular hole of the first workpiece, serves the effect of positioning.Swelling inclined-plane 12 is close to the end face of bottom block 11 Diameter is more than the diameter of the end face away from block 11.The minimum diameter on swelling inclined-plane is interference fitted with sleeve.Connection screw thread 13 The top of connecting bolt is extended upwardly to along the minimum diameter on swelling inclined-plane.In addition, bottom block 11 and swelling inclined-plane 12 it Between the first groove 14 can also be set, the second groove 15, the first groove can also be set between connection screw thread and swelling inclined-plane 14th, the setting of the second groove 15 facilitates the processing and manufacture of connecting bolt.
Sleeve 2, including at least two pieces of separate cell blocks, below by taking the sleeve that three pieces of separate unit blocks are formed as an example Illustrate, respectively first module block 21, second unit block 22 and third unit block 23.First module block 21, second unit Block 22 and third unit block 23 form the tube-in-tube structure of annular by jump ring 3, set at least one recessed on the excircle of sleeve Groove 24, jump ring are positioned in groove 24.In addition, the sleeve inner circumferential surface 25 formed by polylith cell block is inclined plane, therefore Inwall per module unit block is also inclined.The inclined plane is engaged with the swelling inclined-plane of connecting bolt, so as to be advantageous to sleeve Radially it is extended.And the excircle of sleeve side face formed by polylith cell block is the surface being interference fitted with workpiece.
Pressing plate 4, the pressing plate are pressed in the free end of second workpiece.Pressing plate 4 is provided with mounting hole, and connecting bolt passes through mounting hole It is connected with attaching nut, connecting bolt carries out gap cooperation with pressing plate 4.
During specific implementation, with gradually tightening for attaching nut, the bottom block of connecting bolt gradually pastes with the first workpiece Close, the swelling inclined-plane of connecting bolt gradually extends in sleeve vertically, so that sleeve radially swelling second workpiece and the The connection of one workpiece face of weld, so as to ensure that the first workpiece and second workpiece axiality and perpendicularity.When being welded Due to the swelling of sleeve, the temperature distortion of the first workpiece and second workpiece is also significantly reduced.After welding terminates cooling, loosen and connect Connected nut, loosen connecting bolt, sleeve resets in the presence of jump ring, so that welding positioning tool and welding workpiece (the One workpiece and second workpiece) it is separated, complete the process entirely welded.
Described above is the preferred embodiment that the present invention joins, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also regard For protection scope of the present invention.
