Description
Technical field
The present invention relates to a kind of tooling, in particular to a kind of compressor housing tooling.
Background technique
Side on compressor housing is provided with several window sides, and the distance of window side to casing center is a key
Dimensional parameters.In the actual processing process, due to being influenced by factors such as machine tool accuracy, error of cutter, window side to shell
The actual range at body center can and design size there are certain deviations, it is therefore desirable to processing when the size is measured,
It will measure size and be compared with design size, if measuring size in the margin of tolerance of permission, which is qualification, conversely, then
It needs further to correct workpiece.But in the actual processing process, window side existing apart from size to casing center
Measurement is got up very difficult.
Summary of the invention
Present invention aim to address compressor housing, the distance of window side to casing center is difficult to survey in process
The problem of amount, provides a kind of compressor housing tooling, can effectively solve the problem that the above problem.
The purpose of the present invention is what is be achieved through the following technical solutions: a kind of compressor housing tooling, including bottom plate, described
It is provided with the positioning convex platform with work pieces mate on bottom plate, several are provided on the bottom plate and is removably used to carry out workpiece
The positioning pin of positioning, the centre of the positioning convex platform are provided with newel, are provided on the newel for carrying out to workpiece
The pressing device of compression is provided with several measurement datums parallel with the window side on workpiece on the bottom plate.
In the present invention, one end of workpiece is placed on, and positioning convex platform is inserted into the centre bore on workpiece, and positioning pin is inserted
Enter in the location hole on workpiece, is then compressed workpiece using pressing device.Multiple dismountable positioning pins are provided on bottom plate,
It can be directed to different types of workpiece, the installation site of selective positioning pin allows the invention to the workpiece suitable for multiple types.
Each measurement datum can be measured to tooling center apart from size in advance, when workpiece actual installation, workpiece centre with
The center of tooling coincide, and therefore, as long as measuring the distance between window side and measurement datum of workpiece, can measure indirectly
The window side of workpiece size at a distance from workpiece centre.In actual measurement, only window need to be measured by the measurement probe on lathe
Mouth face and the distance between measurement datum parallel therewith, can easily calculate in the window side and workpiece of workpiece
The heart apart from size, measurement process is simple and convenient.Multiple measurement datums are provided on bottom plate, respectively and on different workpiece
Window side is parallel, is just able to satisfy the measurement demand of different workpieces in this way.
Preferably, the side of bottom plate is arranged in the measurement datum.
Preferably, being provided with pedestal below the bottom plate, cushion block is provided between the pedestal and bottom plate.Pedestal peace
On machine tool, it is bolted between cushion block and bottom plate, pedestal.Cushion block is capable of the height of regulating base board, meets
Relative positional relationship between workpiece and lathe.
Preferably, being provided with dowel hole corresponding with positioning pin on the bottom plate, the dowel hole bottom is set
It is equipped with magnetic patch, the positioning pin is inserted into dowel hole.After positioning pin is inserted into dowel hole, magnetic patch can inhale positioning pin
Firmly, to play the fixed function to positioning pin.By this connection type, the dismounting of positioning pin is facilitated.
Preferably, the pressing device includes pressing plate and locking nut, the pressing plate is slidably connected on newel, institute
It states locking nut to be threaded on newel, pressing plate is located at the lower section of locking nut.Pressing plate is pressed in the upper end of workpiece, passes through rotation
Tight locking nut compresses workpiece.
Preferably, the locking nut includes outer ring and inner ring, the outer ring and inner ring coaxial arrangement, the inner ring with
Newel is threadedly engaged, and is provided at least one first skewback on the outer ring surface of the inner ring, the outer ring towards inner ring one
Side is provided with skewback slot corresponding with the first skewback, and the second skewback, second skewback are slidably connected in the skewback slot
Spring is provided between the bottom of skewback slot；It is oblique that first skewback close to one end of the second skewback is provided with the first guiding
Face, second skewback is provided with second guiding surface parallel with the first guiding surface close to one end of the first skewback, described
First guiding surface is engaged with the second guiding surface.Two end faces of inner ring are higher than two end faces of outer ring.Locking nut
When screwing, outer ring is rotated, outer ring when rotated, is delivered torque in inner ring and drive by the second skewback and the first skewback
Circle rotation, while the second skewback will receive the reaction force of the first skewback, reaction force acts of second skewback in the first skewback
It is lower mobile to skewback trench bottom, while spring can be compressed, when the first skewback to the reaction force of the second skewback in the second skewback
When component in axial direction is identical as the elastic force of spring, the first skewback and the second skewback are in dynamic balance state.If the torque of outer ring
It is excessive, this balance can be broken, so that the second skewback can overcome the elastic force of spring mobile until the first skewback to skewback trench bottom
It is detached from the second skewback, so that the phenomenon that skidding is generated between outer ring and inner ring, so that the torque of outer ring can not be transferred to inner ring.
By this structure, restriction effect is played to torque, avoid locking nut workpiece is caused due to screwing force is excessive it is excessive
Pressure, effectively prevent workpiece and be subject to crushing.
Preferably, the side of the outer ring is provided with sleeve.It, can be by spanner or metallic rod when tightening locking nut
It is inserted into sleeve, convenient for being tightened to locking nut.
Preferably, being provided with gasket between the locking nut and pressing plate.Gasket can be equal by the pressure of locking nut
It is even to pass to pressing plate.
The beneficial effects of the present invention are: the present invention in the measurement datum being arranged on bottom plate by can easily measure
The window side of workpiece is to workpiece centre apart from size out；The present invention can effectively prevent workpiece when compressing to workpiece
It is subject to crushing, plays a good protective effect to workpiece.
