Specific embodiment
The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model
Among described scope of embodiments.
The biting connecions work holder of the present embodiment, as shown in figure 1, it include pedestal 1 and two it is corresponding linear
Jaw 2, jaw 2 is correspondingly located at pedestal 1, and jaw 2 includes the first frustum 21, the second frustum 22 and groove 23, the first frustum
21 top side location is higher than the top side location of the second frustum 22, the top surface of the top surface width less than the second frustum 22 of the first frustum 21
Width, the first frustum 21 and the second frustum 22 are spaced apart, groove 23 be located at adjacent the first frustum 21 and the second frustum 22 it
Between, the first frustum 21, the second frustum 22 and groove 23 are arranged in a straight line.First frustum 21 is used to penetrate workpiece blank surface, the
Two frustums 22 are used to withstand blank surface, after penetrating workpiece blank surface due to the first frustum 21 chip, groove 23 can be produced to use
In accommodating and discharging the chip of blank surface, by the mating reaction of the first frustum 21 and the second frustum 22, can be in workpiece hair
Still workpiece blank is firmly clamped in the case that the base thickness depth of parallelism is relatively low.
The apical side height difference of the top surface of the first frustum 21 and the second frustum 22 is 0.4 to 0.6 millimeter.The top of the first frustum 21
Face is the depth that the first frustum 21 penetrates workpiece blank surface with the apical side height difference of the second frustum 22.Difference in height be 0.4 to
At 0.6 millimeter, both can effectively firm clamping workpiece blank, and workpiece blank surface do not done great damage.Table 1 shows
Under the clamping force of 100N, workpiece blank clamping torque and surface quality under different differences in height.
Table 1
| Difference in height (mm) | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 |
| Clamping torque (Nm) | 73 | 87 | 95 | 101 | 106 |
| Roughness (Ra) | 56 | 74 | 92 | 123 | 168 |
The apical side height difference of the top surface of the first frustum 21 and the second frustum 22 is 0.5 millimeter.From table 1 it follows that with
The increase of difference in height, the increase of clamping torque is tended towards stability, but roughness is sharply increased, and is considered, difference in height is 0.5
It is the most favourable to clamping during millimeter.
The top surface width of the first frustum 21 is 0.2 to 0.4 millimeter, and the top surface width of the second frustum 22 is 1.2 to 1.4 millis
Rice.First frustum 21 needs enough intensity, while workpiece blank can be penetrated again, therefore width can not be too narrow, and can not be too
Width, the width of 0.2 to 0.4 millimeter of the top surface of the first frustum 21 can meet such requirement, and the second frustum 22 needs to withstand hair
Base surface, therefore width is wider than the top surface of the first frustum 21, the present embodiment takes the top surface width of the second frustum 22 than the first cone
The top surface width 1mm wide of platform 21.Table 2 shows that under the clamping force of 100N the maximum of jaw 2 bears torque and the first frustum 21
Penetrate depth.
Table 2
| First frustum top surface width (mm) | 0.1 | 0.2 | 0.3 | 0.4 | 0.5 |
| Maximum bears torque (Nm) | 32 | 54 | 78 | 90 | 98 |
| Penetrate depth (mm) | 0.29 | 0.17 | 0.12 | 0.09 | 0.03 |
From Table 2, it can be seen that the maximum for considering jaw 2 bear torque and the first frustum 21 penetrate depth,
The top surface width of one frustum 21 is 0.3 millimeter ideal, and correspondingly, the top surface width of the second frustum 22 is 1.3 millimeters.First
Most favourable to clamping when the top surface width of frustum 21 is 0.3 millimeter, the top surface width of the second frustum 22 can be very when being 1.3 millimeters
Blank surface is withstood well, realizes firmly clamping.
Groove 23 is semi-cylindrical, and the axis of the place cylinder of groove 23 is vertical with jaw 2.The groove 23 of semi-cylindrical is easy
Processing, while being easily drained chip.
The bottom surface of the first frustum 21 and the second frustum 22 is rectangle.The frustum of rectangle is easily worked.
Jaw 2 also includes escape groove 24, and escape groove 24 is 3/4ths cylindrical cavities, the axis and jaw of escape groove 24
2 is parallel.Escape groove 24 is used to accommodate the flash of workpiece blank, and the escape groove 24 of cylinder is easily worked, while being easily drained broken
Bits.
Pedestal 1 also includes fixture block 3, as shown in Fig. 2 jaw 2 is located on fixture block 3, fixture block 3 is bolted pedestal 1
On.Fixture block 3 can be changed, therefore can change various sizes of jaw 2.
The biting connecions work holder of the present embodiment can be in the case where the workpiece blank thickness depth of parallelism be relatively low still
Workpiece blank is firmly clamped.
