Example (b):

as shown in fig. 1-4, the utility model provides an axle connecting plate fixes a position fast and bores anchor clamps of attacking, including base 1, support piece 2, roof 3, clamping piece 4 and clamping screw 5. The supporting members 2 are provided in pairs to the base 1. The two stays 2 disposed in pair are disposed oppositely so that a placing groove for placing the axle connecting plate 7 is formed between the two stays 2. The width of the placement groove corresponds to the length of the axle connection plate 7, so that the axle connection plate 7 can be placed in the placement groove. One end of each support 2 far away from the base 1 is provided with a top plate 3. One side of the top plate 3 extends to the upper side of the placing groove, and the lower surface of the part of the top plate 3 extending to the upper side of the placing groove is a plane. The bottom of the support member 2 is provided with a sliding groove, and the clamping member 4 is arranged inside the support member 2 and can slide along the sliding groove along the height direction of the support member 2. The support member 2 is provided with a coupling hole along its height direction in cooperation with the clamping member 4. The clamping screw 5 is inserted through the attachment hole and is screwed to the clamping member 4. The clamping member 4 can be driven to slide relative to the supporting body by rotating the clamping screw 5. The bottom of the clamping piece 4 extends into the placing groove and the part extending to the placing groove is opposite to the part of the top plate 3 extending to the inner part of the placing groove.

The utility model discloses a when axle connecting plate is fixed a position fast and is bored tapping anchor clamps and use, clamping screw 5 is rotatory for clamping piece 4 descends the extreme lower position. At this time, the axle connecting plate 7 can be easily pushed into the placement groove from the side thereof, and both sides of the axle connecting plate 7 are respectively placed between the set of top plate 3 and the clamping member 4. Then insert the location axle fast, the connecting plate relies on the interact of fixed top piece and elasticity top piece, realizes automatic corner location (need not manual intervention) afterwards, twists clamping screw 5 rotatory for clamping piece 4 rises, and then makes axle connecting plate 7 press from both sides tightly between roof 3 and clamping piece 4, conveniently carries out drilling tapping processing to axle connecting plate 7. The processed holes and the connecting plate are symmetrically distributed in shape, so that the problem of poor quality and poor quality caused by inaccurate positioning is solved

The fast positioning, drilling and tapping clamp for the axle connecting plate is used for positioning through the attachment of the top plate 3 and the axle connecting plate 7. And the matching surface of the axle connecting plate 7 and the top plate 3 is precisely machined in advance and assembled to be completely parallel to the bottom surface, so that the positioning is more accurate, and the hole pitch precision of the machined hole and the verticality of the large surface are more accurate.

In this embodiment, the base 1 is further provided with a positioning groove 11. The positioning slot 11 may be a slot opened in the base 1. Or may be a part attached to the base 1. In this embodiment, the positioning groove 11 is a hollow column. The lower end of which is connected to the base 1. A positioning shaft 6 is inserted in the positioning groove 11. The positioning shaft 6 is matched with a center hole 71 of the axle connecting plate 7 to be arranged, so that when the axle connecting plate 7 is placed in the clamp, the positioning shaft 6 penetrates through the center hole 71, and automatic corner positioning and center positioning are realized through interaction of the fixed jacking piece and the elastic jacking piece.

When the axle connecting plate is used, the axle connecting plate 7 is placed in the placing groove, and then the center hole 71 of the axle connecting plate 7 is aligned with the positioning groove 11. Subsequently, the positioning shaft 6 is inserted into the positioning groove 11, so that the axle connecting plate 7 is limited through the positioning shaft 6 and limited angularly through the fixed jacking piece. Thereby avoiding the displacement or movement of the axle connecting plate 7 in the processing process.

In this embodiment, two positioning seats 8 are disposed at one end of the placing groove of the base 1. Two positioning seats 8 are provided with fixed top member 9 and elasticity top member respectively. The fixed tightening member 9 includes a tightening screw 91 and a set nut fitted to the tightening screw 91. The tightening screw 91 is connected to the positioning socket 8 and extends into the placement groove. The jacking screw 91 is abutted to the axle connecting plate 7 so as to jack the axle connecting plate 7 tightly. The tightening degree and the angular positioning can be adjusted by adjusting the tightening screw 91. After the position of the tightening screw 91 is adjusted, the tightening nut is screwed to abut against the positioning seat 8, so that the tightening screw 91 can be locked. The elastic top member is provided with a spring 10 on the basis of the fixed top member 9. And the angular positioning of the connecting plate is automatically realized by the interaction with the fixed jacking piece.

In particular use, the axle web 7 is pushed into the placement groove and one side of the axle web 7 is brought into abutment against the fixed ejector 9 and the spring 10. When the positioning shaft 6 is inserted into the center hole 71, the positioning shaft 6 pushes the axle connection plate 7 to move slightly, thereby pressing the spring 10. This also makes axle connecting plate 7 be fixed in the utility model discloses an axle connecting plate 7 is pushed tightly by spring 10 when the anchor clamps are attacked to axle connecting plate quick location brill, realizes centering alignment automatically.

In this embodiment, the top plate 3 is bolted to the top of the support 2. This enables the top plate 3 to be replaced according to the size of the axle link plate 7, so that the top plate 3 always corresponds to the model of the axle link plate 7.

In the present embodiment, two pairs of the supporting members 2 are provided. Each pair of support members 2 is cooperatively provided with a top plate 3, a clamping member 4 and a clamping screw 5. This just makes once can two axle connecting plates 7 of clamping simultaneously, and then once processes two, improves production efficiency.

The two pairs of supports 2 are distributed along a straight line so that the two standing grooves are arranged side by side. Two support members 2 adjacent to each other are connected as a single body. The number of the supporting pieces 2 is small, and the assembly is quick. And simultaneously, the processing is simpler.

In this embodiment, a positioning pin 12 is disposed on a side of the base 1 away from the support 2. The positioning pin 12 is matched with a positioning key groove of the workbench to realize quick installation and positioning of the clamp. When base 1 connects in the workstation of lathe, locating pin 12 pegs graft in the location keyway of workstation, and then makes base 1 can quick location for the workstation.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
