Abstract

The utility model discloses an arc-shaped clamping plate drill. The arc-shaped clamping plate drill comprises a drilling template, a base, a machine frame and a bit, wherein the base is concave, and is fixed on the machine frame; drill holes are formed in the two ends of the upper surface of the drilling template; a hole is formed in the center of the drilling template; a pillar is inserted into the hole in the center of the drilling template; a handle is arranged at the upper end of the pillar; an extruding block is fixed at the bottom end of the pillar; the pillar penetrates through a spring located in the centers of the extruding block and the drilling template; the length of the spring in the natural state is longer than a distance from the extruding block to the upper surface of the drilling template; a groove is formed in the concave part of the base; the arc-shaped of a clamping board is placed in the groove. After the adoption of the structure, when drilling is performed, the clamping board is limited by the concave groove of the base and the extruding block, so that only the bit penetrates through the drill holes to punch the clamping board during processing, and line marking is needless; in addition, when the placing position of the clamping board is fixed, the positions of holes punched in the clamping board are the same, accordingly, the phenomenon of hole deflection is avoided when the clamping board is used.

Description

A kind of curved splint drill

Technical field

The utility model relates to a kind of drilling instrument, particularly a kind of curved splint drill.

Background technology

Curved splint is one of common product of mechanized equipment, for attached cable or other section bars, to curved splint punching is main, adopt manual line to determine hole site at present, the process of boring again, due to manual operations, normal upper lower plate off(-)center or the two connecting hole off(-)center phenomenons of occurring, cause clamping plate normally not use.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of curved splint drill, and this curved splint drill can not need to carry out the i.e. accurate position of locating hole of manual setting-out, and in this position punching.

For achieving the above object, the utility model provides following technical scheme: a kind of curved splint drill, comprise bushing plate, base, frame and drill bit, bushing plate is fixed on base, base is spill, base is fixed in frame, the upper surface two ends of bushing plate have boring, the center of bushing plate arranges hole, the hole of bushing plate center is divided into two sections, the diameter in hole increases progressively from top to bottom successively, an interspersed root post in the hole of bushing plate center, column upper end arranges handle, a crushing block is fixed in column bottom, column is interspersed spring between crushing block and the hole of bushing plate center, the length of spring under nature is greater than the distance of described crushing block to bushing plate upper surface, the recess of base arranges groove, the arch section of clamping plate is placed in groove, and the surface of described crushing block contact clamp, base arranges backing pin in the position of placing clamping plate wing plates on two sides.

Preferably, in two borings, drill bushing is all set.

Adopt technique scheme, a kind of curved splint drill, comprise bushing plate, base, frame and drill bit, bushing plate is fixed on base, base is spill, base is fixed in frame, the upper surface two ends of bushing plate have boring, the center of bushing plate arranges hole, the hole of bushing plate center is divided into two sections, the diameter in hole increases progressively from top to bottom successively, so that spring is all the time between crushing block and hole, do not skid off hole, an interspersed root post in the hole of bushing plate center, column upper end arranges handle, convenient with hand application of force lifting column, a crushing block is fixed in column bottom, column is interspersed spring between crushing block and the hole of bushing plate center, the length of spring under nature is greater than the distance of described crushing block to bushing plate upper surface, be convenient to the tension force squeezing splints of crushing block by spring, make clamping plate at above-below direction upper limit, the recess of base arranges groove, the arch section of clamping plate is placed in groove, avoid clamping plate when boring to occur double swerve, base arranges backing pin in the position of placing clamping plate wing plates on two sides, be convenient to stop that clamping plate wing plates on two sides moves forward and misses the position of groove during clamping plate placing, adopt said structure, when boring, because base groove and crushing block have defined clamping plate, therefore add man-hour only need to by drill bit through boring to clamping plate, punch, do not need to carry out setting-out, and when the position of placing clamping plate is fixing, the position in the hole of beating on clamping plate is also identical, thereby there will not be the phenomenon that occurs hole dislocation during clamping plate using, in two borings, drill bushing is set, avoids drill bit contact boring to cause borehole damage to affect borehole accuracy.

Wherein, 1. bushing plate 2. base 3. handle 4. hole 5. column 6. crushing block 7. spring 8. grooves 9. 10. clamping plate 11. backing pin 12. drill bushing 13. frame 14. drill bits 15. of holing are sold.

The specific embodiment

Below in conjunction with accompanying drawing, by the description to embodiment, the utility model is described further:

Fig. 1 is structural representation of the present utility model, Fig. 2 is clamp region schematic diagram of the present utility model, a kind of curved splint drill of the utility model, comprise bushing plate 1, base 2, frame 13 and drill bit 14, bushing plate 1 is fixed on base 2 by pin 15, base 2 is spill, base 2 is fixed in frame 13, the center of bushing plate 1 arranges hole 4, the upper surface two ends of bushing plate 1 have boring 9, at two boring 9 interior drill bushings 12 that arrange, avoid drill bit 14 contact boring 99 damages that cause holing to affect borehole accuracy, the hole 4 of bushing plate 1 center is divided into two sections, the diameter in described hole 4 increases progressively from top to bottom successively, so that spring 7 is all the time between crushing block 6 and hole 4, do not skid off hole 4, the interior root post 5 that interts in hole 4 of bushing plate 1 center, column 5 upper ends arrange handle 3, convenient with hand application of force lifting column 5, a crushing block 6 is fixed in column 5 bottoms, column 5 is interspersed spring 7 between crushing block 6 and the hole 4 of bushing plate 1 center, the length of spring 7 under nature is greater than the distance of described crushing block 6 to bushing plate 1 upper surface, be convenient to the tension force squeezing splints 10 of crushing block 6 by spring 7, make clamping plate 10 at above-below direction upper limit, the recess of base 2 arranges groove 8, the arch section of clamping plate 10 is placed in groove 8, avoid clamping plate 10 when boring to occur double swerve, base 2 arranges backing pin 11 in the position of placing clamping plate 10 wing plates on two sides, be convenient to stop that clamping plate 10 wing plates on two sides move forward and miss the position of groove 8 during clamping plate 10 placing.Adopt said structure, when boring, because base 2 grooves and crushing block 6 have defined clamping plate 10, therefore only drill bit 14 need to be punched through 9 pairs of clamping plate 10 of boring man-hour adding, do not need to carry out setting-out, and when the position of placing clamping plate 10 is fixing, the position in the hole of beating on clamping plate 10 is also identical, thereby there will not be the phenomenon that occurs hole dislocation when using clamping plate.

Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
