Abstract
The utility model discloses auxiliary equipment for cloth wheel sewing. The auxiliary equipment comprises a machine frame, wherein a guiding shaft is horizontally mounted on the machine frame; a supporting arm and a driving mechanism are arranged on the machine frame; the driving mechanism drives the supporting arm to slide relative to the guiding shaft; a rotating shaft perpendicular to the working table of a sewing machine is arranged at one end of the supporting arm; and a fixing component for fixing a cloth wheel is arranged at the bottom of the rotating shaft. During the sewing of the cloth wheel, the feed dog and the presser foot of the sewing machine can drive the cloth wheel to rotate around the rotating shaft, and the driving mechanism drives the rotating shaft to slide relative to the guiding shaft, so that the center of the cloth wheel approaches the needle head of the sewing machine gradually, and a sewing thread with a spiral path can be obtained after sewing. The movement of the cloth wheel is taken as power, the utility model has the advantage that the cloth wheel is driven while rotating, so as to obtain the spiral sewing path, and ensure the physical uniformity of the cloth wheel.
Description
Technical field
The utility model relates to the servicing unit of a kind of cloth wheel processing, relates in particular to be used to drive the servicing unit that the cloth wheel moves when utilizing Sewing machines machining cloth wheel.
Background technology
When carrying out timber products surface finish or metal surface polishing, often can use polishing wheel, general polishing wheel is through Sewing machines the multilayer cloth to be sewed together, and then cuts into patty again.
During Sewing machines machining cloth wheel; Be according to the track of screw line the multilayer cloth is made from outside to inside; So cloth not only need rotate but also need the syringe needle of relative Sewing machines do away from or near motion; Only depend on manual operations in the prior art, moving cloth when making is accomplished making of spiral trajectory.
But precision hand-manipulated is low, deviation is big, and the compaction rate of cloth wheel different parts is different, and dynamic balance is bad during high-speed rotation.
The utility model content
The utility model provides a kind of cloth wheel auxiliary processing device, can pivot be provided for the cloth wheel, can drive the cloth wheel simultaneously gradually near the syringe needle of Sewing machines, to accomplish making of uniform spiral trajectory.
A kind of auxiliary equipment that is used for the sewing of cloth wheel; Comprise frame; The axis of guide of horizontal arrangement is installed on the described frame; Be provided with support arm and be used to drive the driving mechanism that support arm slides with respect to the axis of guide, an end of support arm is provided with the rotating shaft perpendicular to the sewing machine table face, and the rotating shaft bottom is provided with the fixed part that is used for fixing the cloth wheel.
The described axis of guide is provided with the axle sleeve that is slidingly matched, and described support arm is fixed on the outer wall of this axle sleeve.
In sewing fabric when wheel,, the feed dog of Sewing machines and presser feet can drive the cloth wheel and rotate around the axis, and driving mechanism drives support arm simultaneously and slides with respect to the axis of guide, makes cloth take turns the center gradually near the Sewing machines syringe needle, make the sewing thread that can obtain spiral trajectory after the completion.
Described fixed part is at least two thimbles that are distributed on the end face of rotating shaft bottom.Can guarantee the relative fixed of cloth wheel and rotating shaft, when the cloth wheel rotates, can drive rotating shaft and rotate synchronously.
As preferably, described rotating shaft is double does worm screw, and described driving mechanism comprises:
The rack-mounted tooth bar that laterally arranges with the axis of guide;
First gear that is meshed with described rotating shaft;
Be meshed with described tooth bar, and be in second gear of same axis with first gear;
The rack-mounted drive link that is used for as first gear and second rotary gear shaft.
Because the cloth wheel is driven by feed dog and presser feet; Therefore described driving mechanism is that the rotation of taking turns with cloth is a power source; Need not the extra power that is provided with; Rotating shaft drives first gear when rotating, and drives second gear through drive link again, and second gear makes whole support arm slide along the axis of guide under the promotion of tooth bar.
The auxiliary equipment that the utility model is used for cloth wheel sewing is a power with the motion of cloth wheel self, in the rotation of cloth wheel, promotes the cloth wheel, obtains uniform screw line sewing path, guaranteed on the cloth wheel physical property evenly.
Description of drawings
Fig. 1 is used for the structural representation (depression angle) of the auxiliary equipment of cloth wheel sewing for the utility model;
Fig. 2 is cloth wheel center among Fig. 1 structural representation after near the Sewing machines syringe needle.
The specific embodiment
Referring to accompanying drawing, a kind of auxiliary equipment that is used for the sewing of cloth wheel of the utility model comprises frame 1, and the axis of guide 2 of horizontal arrangement is installed on the frame 1, and the axis of guide 2 is provided with the axle sleeve 3 that is slidingly matched, and support arm 4 is fixed on the outer wall of this axle sleeve 3.
One end of support arm 4 is provided with the rotating shaft 5 perpendicular to sewing machine table face 9, and rotating shaft 5 bottoms are provided with two thimbles that are used for fixing cloth wheel 7.
Rotating shaft 5 is a worm structure, and an end of support arm 4 is equipped with first gear 10 that is meshed with rotating shaft 5; Second gear 12 and 10 coaxial being arranged on the drive link 11 of first gear.Frame 1 is provided with the tooth bar 13 that laterally arranges with the axis of guide 2, and the tooth bar 13 and second gear 12 match.
During the sewing fabric wheel; The feed dog of Sewing machines and presser feet 6 can drive cloth wheel 7 and 5 rotate around the shaft, and rotating shaft 5 drives first gear 10 when rotating, drive second gear 12 through drive link 11 again; Second gear 12 makes whole support arm 4 slide along the axis of guide 2 under the promotion of tooth bar 13; Promote cloth wheel 7 near presser feet 6, obtain uniform screw line sewing path 8, guaranteed cloth take turns on 7 physical propertys evenly.
