Abstract
The utility model discloses a motor fixing base for a main shaft of a sewing machine. The motor fixing base is characterized by comprising a motor, a coupler, a connection base, a bearing and the main shaft of the sewing machine. The motor comprises a motor transmission shaft and a motor installation base. A sewing machine head comprises the main shaft of the sewing machine and a sewing machine installation base. According to the motor fixing base for the main shaft of the sewing machine, a motor installation base and a transmission shaft bearing installation base in the prior art are integrated and replaced by the connection base, so that the assembly error of the motor installation base and the transmission shaft bearing installation base is removed. Meanwhile, installation holes of the motor installation base and the transmission shaft bearing installation base are machined in the same process, difference of machining error values of the motor installation base and the transmission shaft bearing installation base is reduced, and the coaxiality error is reduced. Thus, the coaxiality error between the motor transmission shaft and the main shaft of the sewing machine is reduced to the maximum degree, and the overall assembly accuracy can be guaranteed.
Description
Technical field
The utility model relates to textile industry, relates in particular to machine spindle draw bail.
Background technology
Motor 1 power transmission shaft for Sewing machines in prior art need connect with shaft coupling 2 with Sewing machines 5 main shafts, and the mount pad 14 of its motor and power transmission shaft mount pad 5 adopts mode separately at present conventionally, is jointly being assembled on base 3 ', as shown in Figure 1.Due to both mount pads mismachining tolerance value difference separately, add rigging error, will produce like this problem of the coaxiality deviation between motor shaft and power transmission shaft.In the time that coaxiality deviation is larger, shaft coupling 2 power of being hit will and then become greatly, and the life-span of shaft coupling 2 can decline, and it is large that the load of motor 1 also becomes.
Utility model content
For above problem, the utility model has made targetedly and has changed for the motor fixing seat of machine spindle, reduces the coaxiality deviation between motor shaft and power transmission shaft, has overcome the existing deficiency of background technology.
The utility model solves the technical scheme that its technical problem adopts:
For the motor fixing seat of machine spindle, it is characterized in that: comprise motor, shaft coupling, Connection Block, bearing and machine spindle, motor comprises motor transmission shaft and motor mount, sewing machine head comprises machine spindle and Sewing machines mount pad; The as a whole framework of Connection Block, framework both ends of the surface are provided with respectively the shaft coupling locating hole, the bearing locating hole that match with shaft coupling and bearing outside diameter, and two locating holes are coaxial; Shaft coupling and bearing are assemblied in respectively on the shaft coupling locating hole and bearing locating hole of Connection Block, and motor transmission shaft and shaft coupling are socketed, connect firmly, and machine spindle passes brearing bore and is assemblied in the other end of shaft coupling and fixes with shaft coupling; Its mount pad of motor, its mount pad of Connection Block and machine spindle are connected in series fixing.
Among one preferred embodiment: its mount pad of described motor is provided with four lugs, lag bolt is fixed motor mount and Connection Block through lug; Also separately be provided with bolt through-hole in Connection Block both ends of the surface, stay bolt, through the bolt through-hole of Connection Block, is connected in series Connection Block fixing with machine spindle mount pad.
Among one preferred embodiment: the two ends of described shaft coupling are radially provided with screw locking hole, two screws are fixed together the motor transmission shaft, machine spindle and the shaft coupling that are inserted into shaft coupling respectively.
The technical program is compared with background technology, and its tool has the following advantages:
1, the utility model is for the motor fixing seat of machine spindle, and the motor mount of prior art and transmission shaft bearing mount pad are integrated and are replaced by Connection Block, deducted both rigging error links.Both installing holes are placed on same operation processing simultaneously, reduce the difference of both mismachining tolerance values, have also reduced the error of axiality.Just maximize thus the error that reduces axiality between motor transmission shaft and machine spindle, can ensure overall assembly precision.
2. in sum, the utility model installation simple in structure, easy to operate, reduce assembly program; Improve assembly precision, increased work efficiency, suitable easily popularization.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the structural representation of prior art.
Fig. 2 has illustrated the schematic perspective view of the utility model for the motor fixing seat of machine spindle.
Detailed description of the invention
Please refer to the motor fixing seat of Fig. 2 for machine spindle, comprise motor 1, shaft coupling 2, Connection Block 3, bearing 4 and sewing machine head 5, motor 1 comprises motor transmission shaft 11 and motor mount 10, and sewing machine head 5 comprises machine spindle 51 and Sewing machines mount pad 52;
The as a whole framework of Connection Block 3, it is coaxial that framework both ends of the surface are provided with respectively 32, two locating holes of shaft coupling locating hole 31, bearing locating hole that match with shaft coupling 2 and bearing 4 external diameters; Shaft coupling 2 and bearing 4 are assemblied in respectively on the shaft coupling locating hole 31 and bearing locating hole 32 of Connection Block; Because both installing holes of shaft coupling locating hole 31, bearing locating hole 32 are placed on same operation processing, reduce the difference of both mismachining tolerance values, also reduce the error of axiality.Just maximize thus the error that reduces axiality between motor transmission shaft 11 and machine spindle 51, can ensure overall assembly precision;
The two ends of described shaft coupling 2 are radially provided with screw locking hole 21, and motor transmission shaft 11 is inserted to shaft coupling 2, and screw locks shaft coupling 2 and motor transmission shaft 11 through a locking hole 21 of shaft coupling 2;
Sewing machine head main shaft 51 locks shaft coupling 2 and electric machine spindle 51 through another locking hole 21 of shaft coupling 2 through bearing 4 endoporus, the other end that is inserted into shaft coupling 2 screw;
Described motor mount 10 is provided with four lugs 12, and short spiral shell 7 bolts are fixing with Connection Block 3 by motor mount 10 through lug 12; Also separately be provided with bolt through-hole 33 in Connection Block 3 both ends of the surface, stay bolt 6, through the bolt through-hole 33 of Connection Block 3, is connected in series fixing by Connection Block 3 with machine spindle mount pad 52.
In sum, the utility model installation simple in structure, easy to operate, reduce assembly program; Improve assembly precision, increased work efficiency, suitable easily popularization.
The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
