The utility model discloses the working process:
the utility model relates to a drilling anchor clamps towards duckbilled hammer preparation explains in the course of the work, combines the figure.
The first embodiment is as follows:
as shown in the main body of the clamp shown in fig. 1-3, the main body of the clamp is clamped on a bench vice which is fixed on a drilling machine, the drilling machine is pressed downwards firstly, so that the central drill is opposite to a positioning hole 5 on the main body of the clamp, and then the central drill is fixed; when the clamp main body is fixed on a bench vice, a sizing block is usually arranged on the bottom surface of the clamp main body, and the sizing block only needs to avoid the positioning hole 5; the clamp body in the embodiment is processed by a processing center, and the size of the center of the positioning hole 5 away from the left side surface of the chip groove 1 needs to be ensured to be consistent with the size of the duckbill hammer 6 required by a drawing. The width of the clamping groove 2 is slightly larger than that of the duckbill hammer 6. Typically, the blank material used in practice is brass square stock of 14mm by 68mm, which is milled to a length of 65mm, as shown in figure 3 for the duckbill hammer 6. The outer dimensions of the brass billet are conventionally 13.8mm by 13.8mm, 0.2mm smaller than the actual dimensions. Thus, it is only necessary that the width of the clamping groove 2 is a standard 14mm, and the duckbill hammer 6 or the blank can be inserted into it.
Practice teaching class conventionality is about 36 people, and during batch processing centre bore, to invert into clamping inslot 2 through milling process's duckbilled hammer 6 for the terminal surface and the chip groove 1 left surface of duckbilled hammer 6 contact, thereby pushes down the drilling machine, accomplishes the processing of centre bore.
As the conventional practice is to alternate practice among about six work types, a teaching class is also available in which bench workers practice (drilling and tapping are usually completed in bench workers practice) is performed first and then milling practice is performed. For such blank materials, a flat surface is conventionally selected as the end surface of the duckbill hammer 6, and if the duckbill hammer is inclined, the duckbill hammer is obliquely and upwards placed, so that the duckbill hammer is obliquely pressed into the inclined accommodating step 7; if the bottom has burrs, the burrs can be pressed into the burr containing groove 8. In this case, the plane leveling process, which is performed by punching and then milling, has some errors, but is within the allowable range of practice.
Copper scraps are generated during each central hole machining, and in order to ensure that the cleaning is reduced during the machining, the chip grooves 4 on the bottom surfaces of the chip grooves 1 can contain part of the copper scraps; during cleaning, the copper scraps can be brushed out through the scrap discharging holes 3 by the hairbrush.
The duckbilled hammer 6 or the blank after the central hole is processed is subjected to blind hole processing through a drill bit with the diameter of 8mm, and automatic centering can be performed due to the existence of the central hole; after the blind holes are machined, machining through holes by a drill bit of 7 mm; finally tapping is carried out by using a 8mm screw tap, and the step can be completed by practice students.
Example two:
as shown in fig. 4, compared with the first embodiment, the depth of the chip-removing groove 1 of the clamp body in this embodiment is larger than that of the clamping groove 2, which is beneficial to containing more copper chips and reducing the cleaning times in the process of machining the central hole.
Example three:
as shown in fig. 5, compared with the first embodiment, the left side of the clamp body in this embodiment is transversely provided with a thread groove 9, and a fine adjustment nut 10 is matched in the thread groove 9, so that the inclined accommodating step 7 and the burr accommodating groove 8 can be reduced. The advantage of this example is that, when the processing of anchor clamps main part, need not ensure the size that the center of locating hole 5 is apart from chip groove 1 left surface, is unanimous with the duckbilled hammer 6 size that the drawing required, only need make the hole apart from the side be greater than the drawing requirement can, so greatly reduced the cost of manufacture. Before use, only the fine adjustment nut 10 needs to be adjusted by the standard manufactured duckbill hammer 6. In addition, when the blank with the inclined surface is processed in the embodiment, the fine adjustment nut 10 is centered to abut against the duckbill hammer 6, so that the influence of the inclined surface can be reduced.
On the basis of the embodiment, the fine adjustment nut 10 can be replaced by a compass with scales, so that after the size of the duckbill hammer 6 is adjusted, the duckbill hammer is rotated backwards by a certain angle, the positioning hole 5 of the blank is machined, and allowance is reserved for milling.
Example four:
as shown in fig. 6 and 7, in this example, compared with the first embodiment, the duckbill hammer 6 processing and the blank processing are distinguished by adding the pi-shaped gasket 11, and the gasket thickness of the pi-shaped gasket 11 is reserved for the blank processing as the control of the surface quality. The pi-shaped gasket 11 is connected with the gasket limiting groove 12 on the clamp body in a matching mode.
Example five:
as shown in fig. 8, 9 and 10, compared with the first embodiment, in the present embodiment, one clamping groove 2 is added, and in two clamping grooves 2, the dimension of the center of the positioning hole 5 of one clamping groove 2 from the left side of the chip discharge groove 1 is consistent with the dimension of the duckbill hammer 6 required in the drawing, while the dimension of the center of the positioning hole 5 of the other clamping groove 2 from the left side of the chip discharge groove 1 is 1mm larger than the dimension of the duckbill hammer 6 required in the drawing, so that a margin of 1mm is reserved for milling and flattening the end surface. Of course, it may not be 1mm in size. For the clamping convenience of the clamp main body, the clamping groove 2 is necessarily at a certain angle. As shown in fig. 10, R in the figure is the distance from the center of the drilling spindle to the center of the drilled hole, which is a machine tool parameter; x1 and X2 are the distance between the hammer hole and the end face and the size of the milling allowance reserved on the distance; d1 is a dimension 0.2mm greater than the width of the duckbill hammer 6, and d2 is the design dimension. The inclination angle of the clamping groove 2 can be obtained by simple calculation. Of course, as shown in fig. 11, a new jig main body can be obtained by changing the inclination direction and calculating, and this figure is embodiment 6. In the two examples, when the clamp body is installed, only the positioning hole 5 which is straight outside the clamp body and is arranged at the upper part is required to be aligned with the drill bit; then the duckbill hammer 6 and the blank are switched and processed, the position can be found according to the positioning hole 5 only by integrally rotating.
The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any right the scheme after the simple transform of the utility model all belongs to the protection scope of the utility model.
