Abstract
The utility model belongs to the technical field of sewing machines and particularly relates to a sewing machine trimming knife rest structure which comprises a base plate. A lower shaft front sleeve installation hole is formed in the base plate, a lower shaft front sleeve is arranged in the lower shaft front sleeve installation hole, the front end of the lower shaft front sleeve stretches out of the lower shaft front sleeve installation hole, and a trimming knife rest is arranged at the front end of the lower shaft front sleeve. Due to the fact that the trimming knife rest is fixed on the lower shaft front sleeve, a casing base plate is easy to machine, the trimming knife rest is easy to assemble, machining accuracy is ensured, the lower shaft front sleeve is made of a material more abrasion-resistant than that of the base plate, the working durability is better, and the axial position of the lower shaft front sleeve can be adjusted in a micro mode to further adjust the position of the trimming knife rest.
Description
Technical field:
The utility model belongs to sewing machine technique field, refers in particular to a kind of Sewing machines thread trimmer shelf structure.
Background technology:
Trimming knife rest 1 on computer flat sewing machine is mounted in the front end (as shown in Figure 1) of the upper axle protheca installing hole 3 on base plate 2 now.Retrain rotation by the upper axle protheca installing hole 3 on base plate 2.Pressing plate 4 is pushed down trimming knife rest 1.Because the size of the upper axle protheca installing hole 3 on base plate 2 is fixed, the position of trimming knife rest 1 on base plate 2 cannot regulate.Meanwhile, base plate 2 is made for cast iron materials, under trimming knife rest 1 and its rubbing action, easily weares and teares, and poor durability, has reduced trimming precision.
Summary of the invention:
The purpose of this utility model is to provide a kind of high Sewing machines thread trimmer shelf structure of position, good endurance, precision of fine-tuning trimming knife rest.
The utility model is achieved in that
Sewing machines thread trimmer shelf structure, includes base plate, is provided with lower shaft protheca installing hole on base plate, be set in lower shaft protheca installing hole, and the front end of lower shaft protheca stretches out outside lower shaft protheca installing hole before lower shaft, and thread trimmer frame is arranged on the front end of lower shaft protheca.
The front end of above-mentioned lower shaft protheca is provided with necking part, and trimming knife rest is sleeved on outside necking part.
The screwed hole that is circumferentially provided with axial setting on the front end face of above-mentioned lower shaft protheca, knife rest pressing plate is sleeved on outside lower shaft, is connected trimming knife rest is fixed by screw and lower shaft protheca.
The advantage that the utility model is given prominence to is compared to existing technology:
1, the utility model is fixed on trimming knife rest on lower shaft protheca, and chassis backplane processing is easier, and trimming knife rest is assembled to and more easily ensures machining accuracy, and the material of lower shaft protheca is also more wear-resisting than base plate, and Work durability is better.
2, the position of trimming knife rest can be finely tuned and then regulate to the axial location of lower shaft protheca of the present utility model.
Brief description of the drawings:
Fig. 1 is the generalized section of background technology;
Fig. 2 is schematic perspective view of the present utility model;
Fig. 3 is generalized section of the present utility model.
Detailed description of the invention:
With specific embodiment, the utility model is further described below, referring to Fig. 2-3:
Sewing machines thread trimmer shelf structure, include base plate 10, be provided with lower shaft protheca installing hole on base plate 10, lower shaft protheca 20 is arranged in lower shaft protheca installing hole, and the front end of lower shaft protheca 20 stretches out outside lower shaft protheca installing hole, and trimming knife rest 30 is arranged on the front end of lower shaft protheca 20.Lower shaft protheca 20 is copper material, and wearing and tearing between trimming knife rest 30 are little, and Work durability is better, and trimming precision is higher.
The front end of above-mentioned lower shaft protheca 20 is provided with necking part 201, and trimming knife rest 30 is sleeved on outside necking part 201.
The screwed hole that is circumferentially provided with axial setting on the front end face of above-mentioned lower shaft protheca 20, knife rest pressing plate 40 is sleeved on outside lower shaft, is connected fixing trimming knife rest 30 by screw 50 and lower shaft protheca 20.
The position of trimming knife rest 30 can axially be finely tuned and then regulate in the position of lower shaft protheca 20 of the present utility model on lower shaft protheca installing hole.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit practical range of the present utility model with this; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
