Detailed description of the invention
The embodiment of the frock clamp of 1 to 3 pair of a kind of pump housing of this utility model further illustrates below in conjunction with the accompanying drawings.
nullA kind of frock clamp of the pump housing，Including chuck body 1、Upper clamp body 2 and the hold down gag being fixed on clamp body 2，Wherein，Described chuck body 1 center offers through hole，Wear in described through hole and penetrate the off-center adjustment apparatus that can move along through-bore axis direction，Described off-center adjustment apparatus includes sleeve 4 and two eccentric adjustment blocks 5，Described in two, eccentric adjustment block 5 is uniformly arranged on described sleeve 4 on the circumference on upper clamp body 2 one side，The another side relative with the face being fixed on sleeve 4 of eccentric adjustment block 5 described in two is all obliquely installed and two inclined planes are parallel，It is provided with between described upper clamp body 2 and chuck body 1 and the two eccentric corresponding wedges of adjustment block 56，The inclined-plane of eccentric adjustment block 5 is close on the inclined-plane of wedge 6，Described wedge 6 is fixing with upper clamp body 2 to be connected，The limited block I 7 limiting wedge 6 opposed jaw body 1 displacement it is provided with between described upper clamp body 2 and described chuck body 1，Described limited block I 7 is fixing with chuck body 1 to be connected，The limited block II 8 limiting the upper clamp block of described limited block I 7 removal it is provided with on the face at described upper clamp body 2 edge，It is arranged with connecting rod 10 on described sleeve 4，The center of described upper clamp body 2 is provided with the locating ring 3 limiting workpiece location，Described hold down gag is compressed oil cylinder 11.
nullWhen workpiece needs to add man-hour，This frock clamp is fixed on lathe，Workpiece to be processed is put into the locating ring 3 on upper clamp body 2，Hold down gag on clamp body 2 clamping workpiece in adjustment，Workpiece is made to be fixed on clamp body 2，Connect lathe pull bar 12 and connecting rod 10，The sleeve 4 in chuck body 1 through hole is pulled by lathe pull bar 12 and connecting rod 10，Sleeve 4 drives and the fixing eccentric adjustment block 5 connected of sleeve 4 is in axial direction moved，Because the inclined-plane setting of eccentric adjustment block 5 is close on the inclined-plane of wedge 6，As shown in Figure 2，When eccentric adjustment block 5 under the pulling force effect of lathe pull bar 12 to left movement time，Under the effect of eccentric adjustment block 5，Two wedges 6 on upper clamp body 2 move upward，In drive, clamp body 2 moves upward，Move to correct position and can process eccentric orfice，If lathe pull bar 12 pulls sleeve 4 phase left movement always，Wedge 6 is caused to move all the way up，Until the wedge 6 on adjusting apparatus top encounters the limited block I 7 in chuck body 1，Or the limited block II 8 being positioned at adjusting apparatus bottom on upper clamp body 2 encounters limited block I 7 braking in chuck body 1，Avoid because the relative motion of upper clamp body 2 and chuck body 1 causes upper clamp body 2 and chuck body 1 to depart from apart from excessive.
When lathe pull bar 12 band moving sleeve 4 moves right, ibid principle, upper clamp body 2 drives workpiece to be processed to move downward, so just realize disposable machining center hole and eccentric orfice, without secondary clamping, it is ensured that the precision between holes, rate of reducing the number of rejects and seconds, and the processing of products of different specifications can be realized by replacing with the pressing plate compressing fuel tank on clamp body 2, save production cost.
Further, described upper clamp body 2 circumferential edges offers step, the limited block III 9 matched with step it is provided with in described chuck body 1, the limited block III 9 in chuck body 1 is used to coordinate with the step on upper clamp body 2, chuck body 1 and upper clamp body 2 is made to link together, limit the relative motion of axial direction between clamp body 2 and chuck body 1, clamp body 2 can be made again relatively to move in radial directions with chuck body 1 simultaneously.
Further, described step is provided with two, step described in two is arranged on the circumferential edges of described upper clamp body 2 symmetrically, the line of step described in two is vertical with the line of wedge described in two 6, two faces of described step are all parallel with the line of two wedges 6, limited block III 9 all contacts with two faces of step, and this kind of set-up mode can make limited block III 9 uniform force, also upper clamp body 2 can be made only to move along the direction of two wedge 6 lines the restriction of upper clamp body 2 by limited block III 9 simultaneously.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
