Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Lifting platform
The lifting platform is used for driving the sizing sleeve to lift, auxiliary equipment such as a forklift can be used for transferring the sizing sleeve to the lifting platform, and the lifting platform is also used for adjusting the height of the sizing sleeve to enable the sizing sleeve to be aligned with the opening of the outer box body.
The elevator platform is a device known in the prior art, and the selection of the elevator platform is carried out according to the size and the weight of the sizing sleeve.
Guide rail and flange tray support block
The flange plate supporting block is positioned at the bottom of the flange plate in the assembling process, the guide rail is used for guiding the movement of the flange plate supporting block, and the guide rail can be replaced by structural members with small dynamic friction force when the axial direction is fixed and the relative movement is carried out, such as an optical axis and the like. The guide rail sets up on the elevating platform, and stable in structure is reliable.
Roller capable of being lifted
The roller is in rolling contact with the outer surface of the sizing sleeve, and the flange supporting block and at least two rollers are combined into a multipoint bearing structure to disperse stress. The wheel surfaces of the rollers are arranged in a staggered mode, namely the rollers are not sequentially arranged along the axial direction of the guide rail in theory. Because the roller is in rolling contact with the sizing part extending into the outer box body, when the flange plate supporting block approaches the roller, the roller moves downwards to the lower part of the flange plate supporting block to push the flange plate supporting block to enable the flange plate to be attached to the end face of the outer box body, and bolts and the like are installed. Therefore, the diameters of the lifting piece for supporting the roller and the roller determine the stroke of the flange plate supporting block towards the outer box body after the roller descends, and therefore the diameters of the lifting piece for supporting the roller and the roller are controlled to be smaller.
Driving member
The driving part is used for driving the flange plate supporting block to slide along the guide rail in a reciprocating mode, and comprises but is not limited to a cylinder, an oil cylinder and a driving part consisting of a motor and a transmission assembly, wherein the transmission assembly can output the rotation of the motor into linear motion, such as a lead screw nut transmission part, a worm and gear transmission part and the like.
Caster wheel
The interval of extrusion equipment and vacuum sizing equipment is little, and for convenience of the operation of sizing sleeve material loading on fork truck etc. the truckle helps adjusting the position of elevating platform.
Screw hole and bolt of bottom support block
The position of the sizing sleeve needs to be fixed in the installation process. The bottom support block is a cambered surface, which is beneficial to limiting the position of the bottom support block, and in the actual operation process, a limiting block can be filled between the bottom support block and the flange plate so as to fix the position of the sizing sleeve. Furthermore, the adjusting bolt protrudes out of the top surface of the bottom support block to reach the effect of a limiting sizing sleeve. The number of the bolts is two and the bolts are arranged at intervals.
Positioning hook
When the sizing sleeve is placed on the assembling device, the gravity center of the sizing sleeve is positioned between three contact points of the flange plate supporting block and the roller, and the relative positions of the gravity center of the sizing sleeve and the three contact points are changed in the process that the sizing sleeve is pushed into the outer box body; when the gravity center of the sizing sleeve is positioned on one side of three contact points of the sizing sleeve, the flange plate supporting block and the roller, the position deviation of the sizing sleeve can be caused due to unstable gravity center. The positioning hook is used for further fixing the position of the sizing sleeve.
