Problems solved by technology

[0002] Nowadays, there are many processes in the processing of the sewing machine head. In the previous processing process, the assembly surface of the sewing machine head was processed first. clamp to process the front end and rear end of the sewing machine head, and then use the assembly surface as the reference to process the top surface, A surface and B surface of the sewing machine, and then process the spindle hole on the assembly surface as the reference surface, and then Use the main shaft hole as the positioning reference to process the needle bar hole and the pressure bar hole on the top surface of the sewing machine head, so as to ensure the perpendicularity of the main shaft hole, the needle bar hole, and the pressure bar hole, and at the same time process the sewing machine head in the above way, In this way, the process of processing the sewing machine head has more clamping times, which is easy to produce positioning errors, so that the position tolerance of the processing content will produce a large deviation, resulting in a corresponding decrease in the accuracy of the processing content, which will affect the later installation and processing of the sewing machine head. operation; if there are many times of clamping at the same time, the time for clamping will be longer, so there will be a time interval for clamping between each process, which will lead to relatively low processing efficiency, and at the same time cannot guarantee the processing content of the sewing machine head. position tolerance

Embodiment Construction

[0025] Now in conjunction with accompanying drawing, the present invention is further elaborated.

[0026] Such as Figure 1-8 As shown, a processing technology of a sewing machine head includes process one, process two and process three:

[0027] The first process is to place the sewing machine head to be processed on the fixture of the workbench of the vertical machining center, with three points on the A side of the sewing machine head and two points on the top surface, and the direction of the main shaft hole 8 of the sewing machine head at the front end of the sewing machine head. One point on the surface 3 or the rear end surface 4, the three points of the A surface 2 are positioned, and the distribution is that there are two points on the A surface 2 near the rear end surface 4, and one point on the A surface 2 near the front end surface 3. On the A surface 2 near the front end surface 3, there is a point corresponding to the positioning point on the fixture with a bal...

Abstract

The invention discloses a processing technology of a sewing machine head, which includes process one, process two and process three, and the processing content on the sewing machine head that requires position tolerance is carried out on the same device, so that the corresponding clamping error can be reduced and the The position tolerance of these processing contents facilitates the installation and operation of the subsequent sewing machine head.
