Abstract
The utility model belongs to the concrete pump conveying machinery field, and relates to an accurate positioning device used in assembling the concrete pump mounting deck. The technical proposal of the utility model is that: the device comprises an end cover and a tube; wherein, two spiral holes with the symmetrical centers are arranged on the end cover; a boss along the axial direction is arranged at the center of the end cover; the shape of the bass is a circle having outside diameter as same as that of the macrospore of the mounting deck or an inscribed polygon cylinder of the circle; a hole is arranged at the center of the boss; the outer shape of the tube matches with the shape of the central hole of the boss; the diameter of the inner hole of the tube equals that of the principal axis the motor; the tube plugs in the central hole of the boss. The utility model has the advantages that: the people oriented control methods depending on visual inspection on site, the operator technique and so on can be eliminated; instead, the adoption of the utility model can accurately guarantee accuracy of assembling the mounting parts.
Description
Technical field
The utility model belongs to concrete pump conveying mechanism field, the accurate positioning device when relating to the assembling of a kind of concrete pump scaffold.
Background technique
Gear pump is the vitals on the concrete pump, and it provides stirring system and the needed pressure of oscillation system, and its performance quality directly influences oscillation system, whether stirring system can proper functioning.For guaranteeing that gear pump has good working performance, require the main shaft of gear pump and the main shaft of motor must have very high coaxality.During assembling, gear pump is fixed on the scaffold, links by elastic coupling flexible coupling and motor then; Wherein scaffold and motor all be by bolton on vehicle frame.The coaxality of gear pump and electric machine main shaft is that relative position by motor and scaffold guarantees like this, promptly requires the scaffold must be very accurate with respect to the position of motor; If deviation is excessive, can influence the working life and the delivery pressure of gear pump.The assembling of scaffold in the past divided for three steps: 1. assemble elastic coupling flexible coupling is fixed on the electric machine main shaft, and scaffold is placed the relevant position.2. centering is by the φ D hole on the scaffold, and whether the φ d that observes itself and electric machine main shaft centering; Then can't judge as for whether the A face is vertical with electric machine main shaft.3. corresponding bolts on the fastening scaffold, and toothing wheel pump.Like this, during the assembling scaffold, the operator is by perusal, judges the position of scaffold, is difficult to guarantee the position of scaffold; Simultaneously, this method also is subjected to factor affecting such as operator's technical merit, the state of mind, can not guarantee the accurate location of scaffold.
Summary of the invention
The device that the utility model provides when the assembling scaffold, can be determined the scaffold position accurately, thereby guarantee the concentricity requirement of gear pump main shaft and electric machine main shaft.
The purpose of this utility model is achieved through the following technical solutions: this device comprises end cap 1 and body 2, described end cap 1 is provided with centrosymmetric two screws 12, there is an axial convex 13 in end cap central authorities, and it is the circle identical with the big bore dia of scaffold or the inscribed polygon cylinder of circle that convex 13 is shaped as external diameter; Described convex 13 centers are provided with hole 11; The profile of described body 2 matches with the center hole of above-mentioned end cap 11 shapes, body endoporus 21 diameters and the electric machine main shaft equal diameters that connects; Body 2 is plugged in the center hole 11 of convex.
The profile of above-mentioned end cap is circular, also can be the circle that ellipse, rhombus, rectangular or pin go to both sides, and center drilling also can not perforate; The profile of above-mentioned convex center hole, body is that circle also can be other shape; End cap and body can be to be welded into one, and also can be to be cast as one, or alternate manner link into an integrated entity.
Under general machining accuracy, the technical program can satisfy the requirement of the precision of scaffold assembling, and its precision is higher than hand assembled.For further improving the design's precision, can design by following requirement: the concentricity in the inside and outside footpath of its middle tube body is not more than 0.05, and body axis and end cap A face perpendicularity are not more than 0.05.
As further improvement of the utility model, the body endoporus is matched with electric machine main shaft length, increase by one section profile and the body of preceding identical, endoporus 22 diameters at described right-hand member less than connecing electric machine main shaft diameter.
The beneficial effects of the utility model are: cancelled relying on the controlling method with artificial master such as on-the-spot perusal, operator's technical merit, adopted the technical solution of the utility model, can accurately guarantee the assembling set assembly precision.

Embodiment
Embodiment 1
As shown in Figure 1, big bore dia is φ D on the scaffold 5; Motor 4 main shaft diameters are φ d.
This device comprises end cap 1 and body 2, also has with centrosymmetric two screws 12 on the described end cap, and there is an axial convex 13 in end cap central authorities, are provided with center circle hole circle 11 in the convex, and convex is shaped as the cylindrical body that external diameter is φ D; The profile of described body 2 is circular, and its diameter matches with convex center hole 11; One section diameter of body 2 endoporus left ends is φ d, and the diameter that right-hand member is a section is less than φ d; Body 2 is welded in the center hole 11 of end cap.Wherein the concentricity of φ D, φ d is not more than 0.05, and the axis of φ D, φ d and A face perpendicularity are not more than 0.05.
As shown in Figure 2, use this device to carry out the assembling of scaffold, divided for three steps:
1. the location is installed in this device left end on the electric machine main shaft earlier, then with scaffold by being bolted to the other end of this device, with pad scaffold is leveled up, on scaffold, bore positioning hole then.
2. dismounting removes and installs frame, positioning device successively.
3. assemble elastic coupling flexible coupling be fixed on the electric machine main shaft, then with the locating stud fixing and mounting bracket, and use bolton, toothing wheel pump at last.
