Abstract
The utility model provides a fine adjustment needle swing mechanism of a desktop linking machine with a rotating hook and a straight needle. The technical proposal is that an edge cam is fixed on a principal axis, a lever is arranged on a central disc by a centering screw, a bearing at one end of the lever is positioned on the end face which clings closely to the edge cam, a needle arm mechanism is arranged on the central disc by the bearing, a neilsbed is fixed on the shank which is positioned in the needle arm, the other end of the lever is connected with a regulating shank, under the other end of the regulating shank a bearing is arranged, a needle arm pull rod is fixed on the front-end of the needle arm by a screw which passes through a microscler hole, the bearing positioned at the lower-end of the regulating shank is arranged in the hook groove of the needle arm pull rod, moreover the other end of the needle arm pull rod has a socket, and the micrometric regulating screw arranged on the front-end of the needle arm is just blockedly arranged in the socket. When using this structure, by rotating the micrometric regulating screw, the regulating shank can be adjusted; thereby the needle swing mechanism of the linking machine can be adjusted.
Description
Technical field:
The utility model relates to technical field of knitting machinery, refers in particular to a kind of desk-top sewing machine fine adjustment type of hook staight needle needle swinging mechanism that revolves.
Background technology:
Sewing machine is one of visual plant of woolens industry, in order to sew up knitting garment piece, neck, cuff etc.In order to simplify the structure of sewing machine, improve the operating efficiency of sewing machine, people have done a lot of effort, have obtained very big effect.But along with the continuous appearance of novel chemical ﹠ blended fabric and the continuous variation of people's demand, the performance of sewing machine has also been proposed more and more higher requirement, original various sewing machine structures are showed its drawback gradually.As patent name is " a kind of novel desk-top sewing machine of hook staight needle that revolves ", though its than before sewing machine compare, part is improved, but the pin arm brace is fixing irremovable in this structure, can only regulate the position of its swing by regulating shank, involve miscellaneous part during adjusting, very inconvenient.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure with regard to being to overcome the defective of prior art, and can conveniently adjust needle swinging mechanism revolve the desk-top sewing machine fine adjustment type of hook staight needle needle swinging mechanism.
The utility model is achieved by the following technical solution: edge cam is fixed on the main shaft, lever is installed in the mid-game by the centering screw, one end of lever has a bearing on the end face of clip end face cam, the pin arm is installed in the mid-game by bearing, needle stand is fixed on the shank in the pin arm, the other end of lever is connected with the accent shank, below the other end of transferring shank, a bearing is installed, on the pin arm brace elongated hole is arranged, it is fixed on the front end of pin arm by the screw that passes elongated hole, one end of pin arm brace upwards forms a hook-shaped groove, and transfer the bearing of shank lower end just to place in this hook-shaped groove, the other end of pin arm brace has a groove, and the micrometer adjusting screw that is installed in inserting needle arm front end just in time is fastened in the groove.
After adopting this structure, promptly can adjust the pin arm brace, thereby adjust the needle swinging mechanism of sewing machine by the rotary fine adjustment screw, not only convenient but also accurate.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the three-dimensional three-dimensional exploded view of the utility model;
Fig. 2 is the utility model stereogram.
The specific embodiment:
See accompanying drawing 1,2, the utility model comprises: edge cam 1, centering screw 2, lever 3, micro-adjusting mechanism 4, needle stand 5 and pin arm structure 6.Wherein edge cam 1 is fixed on the principal axis A 1, lever 3 is installed in the mid-game 7 by centering screw 2, one end of lever 3 has a bearing 31 on the end face of clip end face cam 1, and pin arm 6 is installed in the mid-game 7 by bearing 63, and needle stand 5 is fixed on the shank 62 in the pin arm 6.The other end of lever 3 is connected with transfers shank 41, below the other end of transferring shank 41, a bearing 46 is installed, elongated hole 481 is arranged on the pin arm brace 48, it is fixed on the front end of pin arm 6 by the screw 43 that passes elongated hole 481, one end of pin arm brace 48 upwards forms a hook-shaped groove 482, and transfer the bearing 46 of shank 41 lower ends just to place in this hook-shaped groove 482, the other end of pin arm brace 48 has a groove 483, and the micrometer adjusting screw 45 that is installed on the pin arm 6 front end sides just in time is fastened in the groove 483.
When using the utility model, utilize spring 8 that lever 3 is pushed up outward, the bearing 31 that makes lever 3 one ends is on the end face of clip end face cam 1, when the edge cam on the principal axis A 11 rotates with principal axis A 1, it will promote lever 3 and swing back and forth around centering screw 2, drive pin arm brace 48 by the bearing 46 of transferring shank 41 and lower end thereof again, thereby drive 6 swings of pin arm.If adjust the swing position of pin arm 6, only need screw 43 is slightly unclamped, turn micrometer adjusting screw 45 makes pin arm brace 48 move to suitable position and gets final product, and so, the swing position of pin arm 6 will obtain adjusting.
The utility model promptly can be adjusted pin arm brace 48 by the rotary fine adjustment screw, thereby transfers the needle swinging mechanism of pin sewing machine, and is not only convenient but also accurate.
