Problems solved by technology

[0005] However, in the case of the above-mentioned prior art, the following problem arises: if an oil groove is provided in the direction in which the actuator is moved and adjusted, the movement of the actuator is restricted in order to avoid contact with the oil groove, etc. action adjustment
[0006] In addition, in order not to limit the movement of the actuator, when restricting the position of the oil tank or the shape of the oil tank, the oil tank may have to be reduced, and the capacity of the oil tank is limited as a result.
In addition, when the capacity of the oil tank is small, the frequency of filling the oil tank with lubricating oil increases as the loss of lubricating oil decreases, so there is a problem that the troublesome work such as maintenance by the user is increased.

Embodiment Construction

[0043] Hereinafter, embodiments of the sewing machine of the present invention will be described in detail with reference to the drawings.

[0044] Furthermore, the direction in which the machine needle 4a described later moves up and down is defined as the Z-axis direction (up-and-down direction), and a direction perpendicular thereto is defined as the X-axis direction (left-right direction). The direction in which both directions are perpendicular is defined as the Y-axis direction (front-rear direction).

[0045]As shown in FIG. 1 , a sewing machine 1 includes a sewing machine frame 2 having a substantially U-shaped outer shape when viewed from a side. This sewing machine frame 2 has: a sewing machine cross arm portion 2a extending in the Y-axis direction constituting the upper portion of the sewing machine 1; a sewing machine bottom plate portion 2b constituting the lower portion of the sewing machine 1 and extending in the Y-axis direction; The vertical fuselage part 2c ...

Abstract

A sewing machine (1), wherein when the arrangement of a solenoid (20) is moved in the front-rear direction in order to adjust the thread-cutting action of a thread-cutting mechanism, an oil groove cover (30) on which the solenoid (20) is mounted ) relative to the sewing machine (1) in its front-rear direction, the arrangement of the solenoid (20) can be switched to a desired position. Especially since the oil groove (10) and the solenoid (20) are installed on the oil groove cover (30), by moving the oil groove cover (30) when moving and adjusting the configuration of the solenoid (20), the oil groove (10) also moves integrally with the solenoid (20), so there are no limitations associated with the movement of the solenoid (20), contact with the oil groove (10), and the like. Accordingly, a sewing machine that can easily adjust the movement of the driver without reducing the capacity of the oil tank is realized.

Description

technical field [0001] The present invention relates to a sewing machine. Background technique [0002] Conventionally, there is known a sewing machine including an oil tank for storing lubricating oil supplied to various sliding parts of the sewing machine in the sewing machine chassis (for example, refer to Patent Document 1). [0003] In addition, a driver (for example, a thread cutting solenoid) for operating a predetermined driving mechanism unit (for example, a thread cutting mechanism unit) of the sewing machine is arranged in the sewing machine chassis. In addition, the driver is fixed to the sewing machine frame through a long hole so that its arrangement can be moved and adjusted in order to adjust the operation of the predetermined drive mechanism. [0004] [Patent Document 1] JP-A-2003-311062 [0005] However, in the case of the above-mentioned prior art, the following problem arises: if an oil groove is provided in the direction in which the actuator is moved ...
