Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, a flat bed sewing machine for sewing cloth includes a left shaft 1, a left fixing sleeve 2 fixedly installed on the top of one end of the left shaft 1, a lower stopping tooth 3 fixedly installed on the outside of one end of the left shaft 1, a rotating rod 4 fixedly sleeved on the middle of one end of the left shaft 1, a right shaft 5 fixedly connected to the other end of the rotating rod 4, a right fixing sleeve 6 fixedly installed on the middle of one end of the right shaft 5 and located at one end of the rotating rod 4, a shaft sleeve housing 7 fixedly sleeved on the outside of the rotating rod 4, an upper stopping tooth 8 fixedly installed on one end of the shaft sleeve housing 7 and located at the outside of the lower stopping tooth 3, an oil inlet pipe 9 fixedly installed on the top of the right fixing sleeve 6 as shown in fig. 2, an oil inlet pipe 9 is filled with lubricating oil in the direction indicated by arrow b, an oil outlet pipe 10 is fixedly installed on the bottom of the right fixing sleeve 6 as shown in fig. 2, and an oil outlet pipe 10 is filled with lubricating oil in the direction indicated by arrow c, when lubricating oil is poured into the machine head, if the lubricating oil is excessive, and a large amount of oil liquid flows downwards, the lubricating oil can be recovered through the oil outlet pipe 10, so that the lubricating oil is prevented from flowing to the inner cavity of the machine head to pollute the environment of the machine head.
The left fixed sleeve 2 and the right fixed sleeve 6 are both circular, the cross section of the side surface of the left fixed sleeve 2 is semi-arc-shaped, the left fixed sleeve 2 and the right fixed sleeve 6 are magnetic, and the left fixed sleeve 2 and the right fixed sleeve 6 pass through an arc-shaped curved surface, so that when lubricating oil is poured into a gap of a rotating part, the pipe diameter of the lubricating oil passing through the gap is smooth in geometric change and free of corner mutation along the gap, so that the lubricating oil is prevented from generating flow velocity distribution for many times in the flowing process, the lubricating oil is prevented from being distributed unevenly, energy consumption caused by corner impact is avoided, and the pouring efficiency of the lubricating oil is effectively accelerated.
Wherein, the outer side surface of the lower railing teeth 3 is corrugated.
Wherein, the inner side surface shape of the upper teeth 8 is S-shaped, the concave-convex direction is opposite to the concave-convex direction of the lower teeth 3, the upper teeth 8 and the lower teeth 3 with specific shapes are adopted, when the lubricating oil flies out along the gap between the left fixed sleeve 2 component and the shaft sleeve shell 7 under the action of the centrifugal force of the rotating rod 4, the protruded ends of the upper teeth 8 and the lower teeth 3 can effectively intercept splashed oil drops, the shapes of the upper teeth 8 and the lower teeth 3 are utilized to carry out mirror image relative position arrangement, the gap change between the upper teeth 8 and the lower teeth 3 is changed from small to large, the height difference between the small gap and the large gap is extremely large, the splashed oil drops in the two sections of suddenly changed gaps have the flow rate changed from fast to slow and the pressure intensity changed from low to high, and the momentum on the wall surface of the gap is not enough to overcome the back-pushing action of the back pressure due to the viscous influence of the oil, so the phenomenon of back flow can occur, cause energy loss, and then effectively stop the motion of splashing, prevent that oil drips the departure, and the curved shape transform in the gap of upper fence tooth 8 and lower fence tooth 3 has increased the geometric change of lubricating oil through the pipe diameter, has further strengthened local resistance, prevents the outflow of fluid, avoids the pollution of oil drips that splashes.
The use method (working principle) of the invention is as follows:
firstly, a lower fence tooth 3 and a left fixed sleeve 2 are sequentially connected and installed on a left shaft element 1, then a rotating rod 4 is fixedly sleeved in the middle of the left shaft element 1, after the sleeving is finished, the other end of the rotating rod 4 is fixedly sleeved and connected with a right shaft element 5, after the sleeving is finished, a shaft sleeve shell 7 is symmetrically sleeved and installed according to the position of an upper fence tooth 8 opposite to the lower fence tooth 3, after the installation is finished, lubricating oil is filled into gaps among all parts through an oil inlet pipe 9, through an arc-shaped right fixed sleeve 6 and the left fixed sleeve 2, the lubricating oil can rapidly slide into the gap between the shaft sleeve shell 7 and the rotating rod 4, the extremely large local resistance of the traditional right-angle connecting gap is avoided, when the lubricating oil is filled, if the lubricating oil is excessive and flows downwards in a large amount, the lubricating oil can be recycled through an oil outlet pipe 10, the lubricating oil is prevented from flowing to an inner cavity of a machine head, and the environment of the machine head is polluted.
When the left shaft piece 1 drives the rotating rod 4 and the right shaft piece 5 to rotate at a high speed, if lubricating oil in a gap flies out along the gap between the fixed sleeve part and the shaft sleeve shell 7, the protruded ends of the upper teeth 8 and the lower teeth 3 effectively intercept splashed oil drops, the gap between the upper teeth 8 and the lower teeth 3 is changed from small to large, the height difference between the small gap and the large gap is very large, and the splashed oil drops are subjected to great flow rate change in the two sections of suddenly-changed gaps, so that energy loss is caused, a turbulent flow phenomenon occurs, splashing motion is effectively stopped, and oil drops are prevented from flying out.
And if the lubricating oil is completely consumed, the lubricating oil is refilled through the oil inlet pipe 9.
