Abstract
The utility model discloses a lathe clamp for a datum hole of a mechanical diaphragm pump. The lathe clamp comprises a clamp body, a pressing bolt, a T-shaped pressure plate, a connecting bolt and a centering pin; the clamp body comprises two parts, wherein one part is a circular plate and the other part is a positioning plate which is connected at a position lower than the center of the circular plate; the centering pin is a stepped shaft for connecting the clamp body with a four-claw chuck of the a lathe; the outer circular surface of the clamp body circular plate is uniformly distributedprovided with four U-shaped slots towards the center, and pressed at the end surface of the four-claw chuck by the connecting bolt; the pressing bolt gets through the T-shaped pressure plate and then is matched with a threaded hole of the clamp body positioning platform, so that the T-shaped pressure plate is pressed at the upper end surface of the pump body. The clamp can quickly machine the datum hole of the mechanical diaphragm pump on a common lathe, so that not only can the machining quality be ensured, but also the production cost is not increased.
Description
Technical field
The utility model relates to the Vehicle Processing frock of Machinery Diaphragm Pump datum hole.
Background technology
At present, along with the development in market, the application of Machinery Diaphragm Pump is more and more extensive, and its demand is also increasing.Machinery Diaphragm Pump is all very high to its processing request of respectively organizing the hole, and each organizes the hole all is to process on the basis of datum hole, so the height of datum hole crudy directly has influence on the crudy that other respectively organizes the hole.The method in existing machining benchmark hole is to carry out hole processing after relying on artificial centering, line, the not only low but also difficult position degree requirement that guarantees the hole of its working (machining) efficiency again; If but buy heavy duty machine tools then invest hugely, cause production cost too high.
Summary of the invention
Problem to be solved in the utility model provides a kind of vehicle clamper of special use, makes on engine lathe the quickly datum hole of processing equipment membrane pump, has both guaranteed crudy, can not increase production cost again.
The vehicle clamper of the utility model Machinery Diaphragm Pump datum hole is characterized in that: it comprises clamp body, hold-down bolt, T-shaped pressing plate, connecting bolt, centring pin; Clamp body comprises two parts, and a part is plectane, and another part is the locating platform that is connected under the plectane center deviation; Centring pin is multidiameter, and it is connected the chuck of clamp body and lathe; The periphery of clamp body plectane is evenly equipped with four U-lags towards the center, be pressed on by connecting bolt on the end face of chuck; Hold-down bolt matches with the screwed hole of clamp body locating platform after T-shaped pressing plate passes, and T-shaped pressing plate is pressed on the upper surface of the pump housing.
When using these anchor clamps, by centring pin clamp body is linked to each other with the chuck of lathe first, and compress with connecting bolt, need process the pump housing is placed on the locating platform again, then beat the plane vertical with datum hole with dial gauge, make its jerk value in the margin of tolerance of the processing pump housing, at last T-shaped pressing plate is placed on the upper surface of the pump housing, hold-down bolt passes screwed hole on the rear screw-in platform from T-shaped pressing plate, and T-shaped pressing plate is pressed on the upper surface of the pump housing.At this moment, the datum hole of the pump housing is processed.This new car anchor clamps can more easily be processed the datum hole of Machinery Diaphragm Pump, have both guaranteed the crudy in hole, improve again process velocity, also can not increase cost.

Fig. 2 is the left view of the utility model vehicle clamper.
Fig. 3 is the top view of the utility model vehicle clamper.
The specific embodiment
From Fig. 1, Fig. 2, Fig. 3 as can be known, the vehicle clamper of this novel mechanical membrane pump datum hole, it comprises clamp body 1, hold-down bolt 2, T-shaped pressing plate 3, connecting bolt 4, centring pin 5; Clamp body 1 comprises two parts, and a part is plectane, and another part is the locating platform that is connected under the plectane center deviation; Centring pin 5 is multidiameter, and it is connected the chuck 6 of clamp body 1 and lathe; The periphery of clamp body 1 plectane is evenly equipped with four U-lags towards the center, be pressed on by connecting bolt 4 on the end face of chuck 6; Hold-down bolt 2 matches with the screwed hole of clamp body 1 locating platform after T-shaped pressing plate 3 passes, and T-shaped pressing plate 3 is pressed on the upper surface of the pump housing 7.
In order to guarantee better the intensity of clamp body 1, below clamp body 1 locating platform, be provided with reinforcement 8.
Before using these anchor clamps, need to process at planer first the footing of the pump housing 7, guarantee that its datum hole center is to the distance of footing.Then the pump housing 7 is gone to lathe, by centring pin 5 clamp body 1 is linked to each other with the chuck 6 of lathe, and compress with connecting bolt 4, again the pump housing 7 is placed on the locating platform, then beat the plane vertical with datum hole with dial gauge, make its jerk value in the margin of tolerance of the processing pump housing 7, at last T-shaped pressing plate 3 is placed on the upper surface of the pump housing 7, hold-down bolt 2 passes screwed hole on the rear screw-in locating platform from T-shaped pressing plate 3, and T-shaped pressing plate 3 is pressed on the upper surface of the pump housing 7.At this moment, the datum hole of the pump housing 7 is processed.Whole anchor clamps are fixed on the lathe chuck with four connecting bolts, and guarantee the axiality of clamp body and machine tool chief axis with centring pin, and fit clearance is not more than 0.01mm.During installation, guarantee the center line of clamp body plectane part and the axiality of machine tool chief axis axis, concentricity tolerance is 0.015mm; The plane K vertical with datum hole is vertical with the lathe spindle axis, and tolerance is 0.03mm.These anchor clamps are convenient and practical, invest littlely, and speed is fast, cost is low.
