Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.
The embodiment of the utility model provides a:
as shown in fig. 1-2, a connecting rod 5 structure for driving a main shaft 10 to rotate comprises a turntable 2 and a connecting rod 5.
The rotary table 2 is positioned in the filamentation machine 1 and fixedly arranged on the main shaft 10, the rotary table 2 is circular, a connecting hole for the main shaft 10 to pass through is arranged in the middle of the rotary table 2, and the rotary table 2 is vertically arranged, namely the end surfaces of the rotary table 2 are respectively arranged towards the left direction and the right direction; the main shaft 10 is fixedly arranged in the connecting hole, extends out of the filamentation machine 1 towards the left side and is used for being mutually butted with the power shaft 6; the right side surface of the turntable 2 is fixedly provided with a movable flange 3 through a bolt 20, the movable flange 3 is fixedly provided with a movable abrasive disc 4 through a screw, and when the main shaft 10 rotates, the movable flange 3 and the movable abrasive disc 4 can be driven to rotate.
The turntable 2 is provided with a matching hole 21 for clamping the connecting rod 5, in this embodiment, the matching hole 21 does not penetrate through the disc, in other embodiments, the matching hole 21 may also penetrate through the turntable 2, and whether the penetration does not affect the implementation of the present technical solution. The matching holes 21 are parallel to the axial direction of the rotary table 2, and the matching holes 21 are used for matching with the connecting rods 5 to drive the rotary table 2 to rotate.
One end of the connecting rod 5 is provided with a hoisting hole 50, and the hoisting hole 50 is used for being connected with a travelling crane or an electric hoist; the other end is provided with a pin head 51 matched with the matching hole 21, and the pin head 51 can be inserted into the matching hole 21.
The matching holes 21 are arranged on the side face of the rotary table 2 in the circumferential direction, when the power shaft 6 and the main shaft 10 are corrected, the rotary table 2 needs to rotate for at least one circle, continuity of rotation of the rotary table 2 cannot be guaranteed when the number of the matching holes 21 is small, in actual situations, continuous rotation of the rotary table 2 can be achieved by arranging at least three matching holes 21, however, the matching holes 21 are just located at proper positions when the connecting rod 5 is matched with the matching holes 21 in the rotary table 2 every time, in order to avoid the situation, especially, the matching holes are arranged into a plurality of matching holes, 6-8 matching holes are preferably adopted for setting, the circumferential density of the matching holes 21 is distributed, and the problem that the matching holes cannot be matched with the connecting rod 5 when the matching holes are not located properly can be avoided.
Since the right side of the turntable 2 is also provided with the movable flange 3 and the movable grinding sheet 4, the matching hole 21 is specially arranged on the left side surface of the turntable 2, namely on the side of the turntable 2 facing the power shaft 6.
In actual operation, the connecting rod 5 is vertically arranged in the length direction, and particularly, the connecting rod 5 is provided with a hoisting hole 50 at the upper end and a pin head 51 at the lower end.
The pin head 51 is perpendicular to the length direction of the connecting rod 5, because the depth direction of the matching hole 21 is parallel to the axial direction of the rotating disc 2, in order to ensure the perfect matching of the pin head 51 and the matching hole 21, the pin head 51 is also perpendicular to the connecting rod 5, it should be noted that the force generated by a crane or an electric hoist on the connecting rod 5 is always vertically upward along the length direction of the connecting rod 5, and the pin head 51 and the matching hole 21 can be perfectly matched only if the pin head 51 and the connecting rod 5 are guaranteed to be perpendicular to each other.
As shown in fig. 5, the pin head 51 is provided with two first pin holes 52, the number of the first pin holes 52 is two, the lower end of the connecting rod 5 is provided with two second pin holes, the number of the second pin holes is also two corresponding to the number of the first pin holes 52, a first threaded hole is formed between the two first pin holes 52, a second threaded hole is formed between the two second pin holes, the first threaded hole and the second threaded hole are connected with each other through a screw, and the first pin hole 52 and the second pin hole are in positioning fit through a pin, so that the fitting accuracy of the connecting rod 5 and the pin head 51 is ensured.
The upper end of the connecting rod 5 is bent towards the position towards which the pin head 51 faces; since the fitting hole 21 is provided on the left side surface of the turntable 2, when the pin joint 51 in the connecting rod 5 is engaged with the fitting hole 21, the connecting rod 5 is not located right above the turntable 2 as a whole, in this case, an additional resistance arm will be generated by the rotation of the connecting rod 5 to the turntable 2, the resistance arm will increase the resistance of the turntable 2, and the effect of the rotation is affected, and assuming that the turntable 2 has a larger thickness, when rotating on one end surface of the turntable 2 and rotating on the section right in the middle of the two end surfaces of the turntable 2, two different effects will be achieved completely, and the latter is easier to rotate the turntable 2; in an actual situation, if the connecting rod 5 is fixedly arranged on the circumferential surface of the turntable 2, the matching condition of the pin head 51 and the connecting rod 5 needs to be comprehensively considered, and a certain movable gap must exist between the pin head 51 and the connecting rod 5, however, the structural design is complex, and the actual size of the turntable 2 needs to be comprehensively considered for comparison; in this technical solution, in order to avoid the situation that the resistance of the connecting rod 5 arranged on the end surface of the rotary disk 2 is increased, especially, the upper end of the connecting rod 5 is bent towards the direction of the spindle nose 51 to a certain extent, that is, the position of the lifting hole 50 is arranged right above the middle of the two end surfaces of the rotary disk as much as possible, so as to ensure the rotating effect.
It should be noted that the pin head 51 is movable in the matching hole 21, and in the process of continuous movement, the connecting rod 5 is driven by a crane or an electric hoist to move, and the pin head 51 can rotate relative to the matching hole 21.
The working principle is as follows:
in the process of correcting the power shaft 6 and the main shaft 10, a part of a shell of the filamentation machine 1 is firstly removed, then a pin head 51 at the lower end of the connecting rod 5 is inserted into a matching hole, it needs to be noted that the inserted matching hole needs to select matching holes which are positioned at the front end and the rear end of the turntable 2 as far as possible, after the connection is completed, a travelling crane or an electric hoist is started to drive the connecting rod 5 to move upwards, as shown in fig. 3 and 4, in the process of rising, the inserted matching hole in the turntable 2 is driven to rotate right above the turntable 2, so that the turntable 2 is intermittently driven to rotate, then the pin head 51 can be inserted into another matching hole at the position of the matching hole at the initial position again, the operation is repeated, the continuous rotation of the turntable 2 is realized, and then the correction of the main shaft 10 and the movable vertical shaft is completed.
Still adopt the process of the aforesaid rotation carousel 2, also can accomplish the dismantlement of the fixed movable flange 3 bolt 20 on carousel 2 to accomplish the change together of movable flange 3 and movable abrasive disc 4.
