Abstract
The utility model discloses a presser foot cam transmission mechanism. The presser foot cam transmission mechanism comprises a thread lifting cam, a presser foot cam, a presser foot cam seat and a presser foot cam sleeve ring, wherein the thread lifting cam, the presser foot cam, the presser foot cam seat and the presser foot cam sleeve ring are connected on a transmission shaft in series in sequence, the front face of the presser foot cam and the front face of the thread lifting cam are arranged in a face to face mode, the presser foot cam and the presser foot cam seat are fixed into a whole through bolts, and the presser foot cam seat tightly holds on the transmission shaft through the presser foot cam sleeve ring. According to the presser foot cam transmission mechanism, the transmission of the presser foot cam is directly driven by the transmission shaft, connection is firmer, and driving is more stable.
Description
Technical field
The utility model relates to presser feet cam drive.
Background technique
As shown in Figure 1, current presser feet cam drive is first that presser feet cam 2 and presser feet cam lasso 4 is fixing, and presser feet cam 2 is connected with presser feet link assembly 5, then be enclosed within together in high-speed needle bar driving cam 6, thread take-up cam 7 is fixed on high-speed needle bar driving cam 6, finally high-speed needle bar driving cam 6 is held tightly on transmission shaft, presser feet cam 2 drives by high-speed needle bar driving cam 6.It is firm not that its shortcoming is to connect, and drives stable not.
Model utility content
Technical problem to be solved in the utility model is just to provide a kind of presser feet cam drive, guarantees to connect firm and drives stable.
Solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of presser feet cam drive, comprise the thread take-up cam, presser feet cam, presser feet cam chair and the presser feet cam lasso that are serially connected in successively on transmission shaft, described presser feet cam and thread take-up cam vis-a-vis arrange, between described presser feet cam and presser feet cam chair, be bolted and be integrated, described presser feet cam chair is held tightly on transmission shaft by presser feet cam lasso.
Preferably, between described presser feet cam and presser feet cam chair, by three bolts that are distributed on three angles of equilateral triangle, fix.
Presser feet cam drive of the present utility model is that presser feet cam and presser feet cam chair are fixed, then be inserted in transmission shaft, then with presser feet cam lasso, presser feet cam chair held tightly on transmission shaft, the transmission of presser feet cam directly drives by transmission shaft, it is more firm to connect, and drives more stable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of presser feet cam drive in prior art;
Fig. 2 is the structural representation of presser feet cam drive in the utility model.
Embodiment
Below in conjunction with Fig. 2, presser feet cam drive of the present utility model is made and being illustrated.It comprises thread take-up cam 7, presser feet cam 2, presser feet cam chair 3 and the presser feet cam lasso 4 being serially connected in successively on transmission shaft 1, presser feet cam 2 and thread take-up cam 7 vis-a-vis settings, the front of presser feet cam 2 and thread take-up cam 7 is male and fomale(M&F), presser feet cam 2 and presser feet cam chair 4 junction surfaces are to be bolted between plane and presser feet cam 2 and presser feet cam chair 4, and described presser feet cam lasso 4 is held presser feet cam 2 to be fixed on transmission shaft 1 tightly.Presser feet cam 2 is connected with presser feet link assembly 5.Between described presser feet cam 2 and presser feet cam chair 4, by three bolts that are distributed on three angles of equilateral triangle, fix, fix for 3 and can reach with minimum bolt optimum fixed effect.
Presser feet cam drive of the present utility model is that presser feet cam and presser feet cam chair are first fixed with bolt, and then integral body is inserted in transmission shaft, with presser feet cam lasso, presser feet cam chair is held tightly again, the transmission of presser feet cam directly drives by transmission shaft, transmission link in the middle of having lacked, it is more firm to connect, and drives more stable.
