Specific embodiment
Below with reference to attached drawing, specific embodiment of the present utility model and embodiment are described in detail, it is described
Specific embodiment only to explain the utility model, be not intended to limit specific embodiment of the present utility model.
Referring to Fig. 4, the fixed clamping device of magnetic force provided by the utility model includes fixed seat 10 and magnet 20；It is described
The datum level 110 of fixed seat 10 is caught in the recessed portion of part, and the installation for installing the magnet 20 is provided on datum level 110
Slot 120, magnet 20 is with the recessed portion by magnetic attraction, so as to which part 1 is fixed in fixed seat 10.It is sucked by magnetic force
Part carrys out clamping parts, and part and datum level 110 can be well attracted by the suction without artificially applying external force, positioning
Effect can be protected.
It is to be appreciated that the fixed clamping device of magnetic force provided by the utility model be mainly used for front it is processed
The part of completion, part as shown in Figures 2 and 3.After fixing the part by clamping device, to arrow position shown in Fig. 3
It is processed.Therefore, the position of the shape of fixed seat 10 and magnet 20 need to keep away position processing according to the structure of part.If part stretches
Part out is shorter, and fixed seat 10 is rectangular.If part rises exhibition, next part is longer, the liter as shown in Fig. 5 dotted lines
Open up position；Then the side of fixed seat 10 sets a supporting table 30 to be used to place the liter exhibition position of part, avoids zero in process
Part shakes.Preferably, fixed seat 10 is integrally formed with supporting table 30, the table top of supporting table 30 is less than the datum level of fixed seat 10
110, table top is adapted to the difference in height of datum level with the height at the liter exhibition position of part, can just put down liter exhibition position and a part
It can keep subject to level.It, need to also be on the datum level 110 according to the practical structures of part if part has downward protrusion
Set for be put into part lower protrusion position groove 130.In the present embodiment, in order to accelerate speed of production and efficiency, datum level
3 mounting grooves 120 and groove 130 be at least set on 110, it is each to pacify in Fig. 4 and Fig. 5 by taking 4 mounting grooves 120 and groove 130 as an example
Tankage and groove simultaneously set a groove between row setting and two neighboring mounting groove.Existing primary only one part of production,
More than one piece then can once be produced using present clamping device, greatly improved the efficiency.
The clamping device is according to SUS430（Stainless iron）With it is preferable it is magnetic under conditions of develop, then fixed seat 10
The processing of 45# steel can be used, magnet 20 is using round strong magnets（Specification Ф 19.5X5MM）.Magnet 20 is packed by being interference fitted
In the mounting groove 120 of fixed seat 10, magnet 20 is fastened in mounting groove 120 and does not loosen.
To ensure that magnet 20 installs gapless with mounting groove 120（I.e. without protrusion）, need to be with grinding machine by the datum level of fixed seat
110 20 surface rubbing of magnet with assembling ensures datum level 110 with the flatness on 20 surface of magnet in 0.01mm.
The fixed seat 10 assembled is mounted on wire cutting board, smooths magnet mounting surface；4 parts are distinguished successively
Being put into magnet positions absorption firm can start converted products.
In conclusion part is sucked using magnetic force in clamping device provided by the utility model, without artificially applying external force dress
Folder because part can be firmly bonded by the suction of magnet with datum level during positioning, greatly reduces the operation difficulty of producers.Together
When, the primary adsorbable more than one piece part of clamping device, so as to improve production efficiency and part quality.
It should be understood that the above is only the preferred embodiment of the utility model only, it is not sufficient to limit this reality
With novel technical solution, for those of ordinary skills, within the spirit and principles of the present invention, Ke Yigen
Increased and decreased according to above description, replaced, converted or improved, and all these technical solutions, it should all belong to appended by the utility model
