Abstract

The invention discloses a special fixture for processing a plum blossom-shaped hole of a double offset ring spanner, having convenient clamping and comprising a bottom plate. The middle of the bottom plate is provided with a through hole mutually cooperating with the plum blossom-shaped hole of the double offset ring spanner; the bottom plate is fixedly provided with an intermediate plate; the middle of the intermediate plate is provided with a punched hole mutually cooperating with the through hole; the intermediate plate is fixedly provided with a left fixed plate and a right fixed plate respectively; a locating slot mutually cooperating with a hand shank of the double offset ring spanner is formed among the left fixed plate, the right fixed plate and the intermediate plate; the left fixed plate and the right fixed plate of the middle of the locating slot are respectively provided with a left mounting groove and a right mounting groove; and the round end of the double offset ring spanner is arranged in a locating cavity which consists of the left mounting groove, the right mounting groove and the locating slot. The invention has the advantages that the special fixture for processing a plum blossom-shaped hole of the double offset ring spanner, having the structure, has convenient clamping and high work efficiency, and can fix double offset ring spanner workpieces well; the position for clamping the workpieces is the same each time, so that frequent tool setting is not needed, and the operation is simple.

Example Embodiment

[0010] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0011] like figure 1 , figure 2 , image 3 As shown, the special fixture for processing the torx hole of the torx wrench includes: a base plate 1, a through hole 4 that cooperates with the torx hole 3 of the torx wrench 2 is opened in the middle of the base plate 1, and the middle plate 5 is fixed by a number of first bolts 15. On the bottom plate 1, a punching hole 6 cooperating with the through hole 4 is opened in the middle of the middle plate 5, and the left fixing plate 7 and the right fixing plate 8 are fixedly arranged in the middle by a plurality of second bolts 16 and a plurality of third bolts 17 respectively. On the plate 5, a positioning groove 10 cooperating with the handle 9 of the ring wrench 2 is formed between the left fixing plate 7, the right fixing plate 8 and the middle plate 5, and the left fixing plate 7 and the right fixing plate 8 in the middle of the positioning groove 10 The left mounting groove 11 and the right mounting groove 12 are respectively arranged on the top, and the circular end 13 of the ring wrench 2 is arranged in the positioning cavity 14 composed of the left mounting groove 11, the right mounting groove 12 and the positioning groove 10.
[0012] like image 3 As shown, when the special fixture for processing the torx hole of the torx wrench with the above structure is working, the special fixture for processing the torx hole of the torx wrench is first fixed on the workbench, and the torx wrench workpiece is clamped on the special fixture for processing the torx hole of the torx wrench. The handle 9 of the ring wrench 2 is fixed in the positioning groove 10, and the round end 13 of the adjustable wrench 2 is fixed in the positioning cavity 14 composed of the left mounting groove 11, the right mounting groove 12 and the positioning groove 10, so that the adjustable wrench 2 The position of the plum blossom hole 3 is directly above the punching hole 6. like figure 1 As shown, the control tool 18 moves downwards and punches out of the plum blossom hole 3, and the punched waste material falls from the punching hole 6 and the through hole 4.
