Abstract
The utility model discloses a kind of milling clampers for the self-positioning clamping of delivery pump main shaft end face circular hole, its milling clamper for being used for the self-positioning clamping of delivery pump main shaft end face circular hole is mounted on milling machine table plane, is made of clamp body, pedestal, cylinder, cylinder bottom plate and workpiece.The milling clamper improves original artificial scroll chuck method of clamping, and using the milling clamper of self-positioning clamping, positioning accuracy is high, improves production efficiency.
Description
Technical field
The utility model relates to a kind of milling clampers for the self-positioning clamping of delivery pump main shaft end face circular hole, belong to mechanical add
Work technical field.
Background technique
Currently, in cement pump truck delivery pump spindle processing, because of its large cylindrical end face equal face of circumference spy of several circular holes
Property, what is mostly used greatly clamps axis outer circle with scroll chuck, it is processed with the mode of Milling Process, this conventional installation way, though
So advantage simple with clamping, without special fixture investment.But because clamping and manually must rotate gripping dogs, production with clamp
Low efficiency is unfavorable for forming the production of assembly line.
Utility model content
The purpose of this utility model is to provide Set and Positioning one kind with high accuracy to be used for delivery pump main shaft end face circular hole certainly
Position the milling clamper clamped.
Its technical solution is: a kind of milling clamper for the self-positioning clamping of delivery pump main shaft end face circular hole, it is characterised in that:
A kind of milling clamper for the self-positioning clamping of delivery pump main shaft end face circular hole is mounted on milling machine table plane, by fixture
Body, pedestal, cylinder, cylinder bottom plate and workpiece are constituted.
The clamp body from top to down, is successively made of top board, the collet that rises, fixing seat, connection swivel nut, described consolidates
Reservation is fixedly installed in base plane, and top board is fixed on fixing seat, and the collet that rises is movably installed in fixing seat inner hole, and rise collet
One end outer circle is male cone (strobilus masculinus), and the elongated slot for being provided in the axial direction with several for elastic shrinkage, male cone (strobilus masculinus) are equipped on its male cone (strobilus masculinus)
Matched with fixing seat with the inner conical surface at position, the conical surface conjunction close or discrete state under, make rise collet clamping, release movement,
Connection swivel nut one end couples with the collet external screw thread that rises, and the internal screw thread of the other end joins with the cylinder piston rod being fixedly installed on pedestal
It connects；
The fixed milling machine table plane of the pedestal, cylinder couple cylinder bottom plate, and cylinder bottom plate is fixedly connected with pedestal；
The workpiece is clamped by collet positioning of rising.
Its technical effect is that: the milling clamper due to using self-positioning clamping improves traditional artificial clamping mode, fixed
Position precision is high, improves production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is clamp body component structure diagram (removing pedestal and cylinder).
Specific embodiment
As shown in Figure 1, a kind of milling clamper for the self-positioning clamping of delivery pump main shaft end face circular hole, it is characterised in that: institute
A kind of milling clamper for the self-positioning clamping of delivery pump main shaft end face circular hole stated is mounted on milling machine table plane, by clamp body
2, pedestal 4, cylinder 3, cylinder bottom plate 31 and workpiece 1 are constituted.
As shown in Figure 1 and Figure 2, the clamp body from top to down, successively by top board 21, the collet 22 that rises, fixing seat 23,
Couple swivel nut 24 to constitute, the fixing seat 23 is fixedly installed in 4 plane of pedestal, and top board 21 is fixed on fixing seat 23, and rise folder
Set 22 is movably installed in 23 inner hole of fixing seat, and the 22 one end outer circle of collet that rises is male cone (strobilus masculinus), is equipped on its male cone (strobilus masculinus) along axial direction
Several elongated slot for elastic shrinkage is offered, male cone (strobilus masculinus) is matched with fixing seat 23 with the inner conical surface at position, is closed in the conical surface
Close under (separation) state, make rise collet clamping, release movement, connection 24 one end of swivel nut couple with 22 external screw thread of collet that rises, separately
The internal screw thread of one end couples with 3 piston rod of cylinder being fixedly installed on pedestal 4；
As shown in Figure 1, the fixed milling machine table plane of the pedestal 4, cylinder 3 couple cylinder bottom plate 31, cylinder bottom plate
31 are fixedly connected with pedestal 4；
As shown in Fig. 2, the workpiece 1 is clamped by the positioning of collet 22 of rising.
Its course of work: being mounted on milling machine table for above-mentioned fixture, manually puts the workpiece in the collet inner hole that rises of fixture,
Cylinder operation, cylinder piston rod downward actuation pull the collet that rises on connection swivel nut whole along fixing seat inner hole position axially downwards
It moves, the long groove face of the elastic shrinkage for the collet that rises, to contract, clamps workpiece (tooth shaft) outer circle under the action of conical surface conjunction is closed.
After the Milling Process movement for opening workpiece, cylinder operation, cylinder piston rod acts upwards, pushes collet entirety edge of rising
Fixing seat inner hole is axially upwardly displaced backhaul, and the long groove face of the elastic shrinkage for the collet that at this moment rises is under conical surface centrifugation, outside bullet
It opens, unclamps excircle of workpiece, the artificial workpiece for taking out completion of processing.
Continue to be manually placed into workpiece, complete the circulation action of above-mentioned clamping, release, realizes the self-positioning clamping of workpiece, pine
Open action process.
