Summary of the invention
The utility model, for solving prior art in use Problems existing, provides the high-speed handpiece that adaptation high-speed cruising, long service life, performance are better.
The technical scheme that the utility model solves existing issue is: a kind of high-speed handpiece, comprise head shell, driving shaft, presser feet cam, thread take-up cam, cam pack, needle bar driver, presser feet drive block, described presser feet cam is provided with the clamping head connecting driving shaft, as improvement, the end of the one or both ends of described clamping head is provided with shirt rim; Described presser feet back of cam and the outer face of shirt rim are connected, described cam pack is the eccentric wheel be arranged on driving shaft, described eccentric wheel and needle bar driver are by first connecting rod anatomical connectivity, and described presser feet drive block presser feet cam is by second connecting rod anatomical connectivity.
As further improvement, described thread take-up cam is provided with another clamping head, and the end of these described clamping head one or both ends is provided with shirt rim; The described thread take-up cam back side and the outer face of shirt rim are connected.
As further improvement, described clamping head shirt rim and cam corresponding position joined together are provided with connecting hole.
As further improvement, described clamping head shirt rim is consistent with the cam outline of connection joined together.
As further improvement, described second connecting rod structure comprises that one end is articulated with long-armed connecting rod on head shell, one end is articulated with presser feet connecting rod on presser feet drive block, the described long-armed connecting rod other end and the other end of presser feet connecting rod hinged, described long-armed connecting rod is provided with the drive block with presser feet cam engagement.
As further improvement, described second connecting rod structure comprises that one end is articulated with long-armed connecting rod on head shell, one end is articulated with the drive link on needle bar driver, described drive link, be articulated with on long-armed connecting rod with the presser feet connecting rod other end, and described drive link is articulated with the arm of force that long-armed connecting rod is formed and is less than the arm of force that presser feet rod hinge connection forms on long-armed connecting rod.
The utility model compared with prior art, its beneficial effect arranges shirt rim on the clamping head of presser feet cam, to increase the transmission area of torsion, increase the arm of force, decrease the damage of clamping head to cam, effectively can extend the service life of cam and increase the moment transmitted, being particularly useful for high speed machine; Cam pack is designed to eccentric wheel, compared to traditional cam, and can from improving the accuracy of manufacture and batch micro operations to a great extent.

Fig. 4 is the structural representation of the utility model needle-bar cam.
Fig. 5 is the structural representation of the utility model clamping head.
Fig. 6-7 is schematic diagrames of the another kind of case study on implementation of the utility model.
Detailed description of the invention
See Fig. 1-5, the implementation case comprises the guide rod 52 of head shell 1, driving shaft 2, presser feet cam 3, thread take-up cam 4, cam pack 5, presser feet drive block 6, location needle bar driver 8 and presser feet drive block 6, presser feet cam 3 is provided with the clamping head 31 connecting driving shaft 2, and the end of the one or both ends of clamping head 31 is provided with shirt rim 32; The outer face of presser feet cam 3 back side and shirt rim 32 is connected, cam pack 5 is for being arranged at the eccentric wheel on driving shaft 2, eccentric wheel is connected by first connecting rod structure 51 with needle bar driver 8, and presser feet drive block 6 is connected by second connecting rod structure 7 with presser feet cam 3.
Certainly, thread take-up cam 4 also can arrange the structure similar with presser feet cam 3, and thread take-up cam 4 is provided with another clamping head 31, and the outer face, shirt rim 32 of thread take-up cam 4 back side and this clamping head 31 is connected.
Presser feet cam 3 or and thread take-up cam 4 be provided with connecting hole 34 with corresponding position, corresponding clamping head 31 shirt rim 32, connecting hole 34 can be screw, connect clamping head 31 and corresponding cam by bolt or screw, corresponding cam can bond with shirt rim 32 or bolt is connected.Clamping head 31 shirt rim 32 is consistent with the outline of the cam of corresponding cooperation.In the space that head shell 1 is limited, do not affect the use of cam, the area of maximized increase shirt rim 32, to increase the arm of force, reduce the damage to cam in torsion transmittance process as far as possible.
Second connecting rod structure 7 comprises that one end is articulated with long-armed connecting rod 71 on head shell 1, one end is articulated with presser feet connecting rod 73 on presser feet drive block 6, the other end of long-armed connecting rod 71 other end and presser feet connecting rod 73 is hinged, and long-armed connecting rod 71 is provided with the drive block 33 coordinated with presser feet cam 3.
Because cam is consumable accessory, alternatively, see Fig. 6, 7, in order to protect presser feet cam 3, second connecting rod structure 7 comprises one end and is articulated with long-armed connecting rod 71 on head shell 1, one end is articulated with the drive link 72 on thread-changing drive block 5, one end is articulated with the presser feet connecting rod 73 on presser feet drive block 6, drive link 72, be articulated with on long-armed connecting rod 71 with presser feet connecting rod 73 other end, drive link 72 is articulated with the arm of force that long-armed connecting rod 71 is formed and is less than the arm of force that presser feet connecting rod 73 is articulated with formation on long-armed connecting rod 71, so that during stroke action small size by thread-changing drive block 5, presser feet drive block 5 is driven to obtain the action of stroke by a relatively large margin by second connecting rod structure 7, the sensitivity of presser feet can be improved.
