Abstract
The utility model discloses a motor brake assembly of an industrial sewing machine. The motor brake assembly mainly comprises an adjustable connecting rod assembly, a lever, a pull rod, a crank, a semicircular iron sheet, a brake pad and a brake assembly; when the motor stops, the brake pad and the brake assembly hug tightly, and the sewing machine is in a brake state; when a pedal plate is stepped down, the stepping force is transferred to the crank through the pull rod, then the crank moves to drive a connector of the semicircular iron sheet so as to enable the brake pad to be departed from the brake assembly; while the pedal plate is stepped down, a blade gets close to a light-operated switch, then the motor is started; when the pedal plate is upwarped, the pull rod drives the crank to move so as to drive the connector of the semicircular iron sheet to enable the brake pad to hug the brake assembly tightly, and then the motor stops; when the pedal plate is upwarped, the blade leaves the light-operated switch, and then the motor disconnects the circuit; the motor brake assembly combines the mechanical brake and the electronic brake, effectively saves electric energy, reduces circuit board damage and prolongs the service life of the motor.

Technical field
The utility model relates to a kind of brakes of d.c. motor, and what be specifically related to is a kind of improvement of industrial sewing machine motor brake assembly.
Background technology
The brake assembly of existing industrial sewing machine motor has two kinds: first kind of clutch motor, and this motor drives with inertia, and the big cost height of electrical loss uses a period of time clutch play big, bad control, noise height; Second kind of electric motor, it is to adopt deceleration of electrons to control motor, immediate current is excessive during owing to braking brake, causes circuit board to burn out easily; Yin Mada is deceleration of electrons in addition, so the buffer time of its startup and braking is too short, damages board easily, and the workman operates uncomfortable.
Summary of the invention
The motor that the utility model provides is the industrial sewing machine motor brake assembly that adopts electric start and mechanical braking to combine, its simple in structure, power saving, and workman's processing ease, leicht fallen D/A, easy to maintenance and durable.
The utility model is achieved through the following technical solutions: industrial sewing machine motor brake assembly mainly comprises adjustable link combination, lever, pull bar, crank, semicircle iron sheet, brake rubber block and brake rim; Described lever is to hang on the motor by axle; Crank is to hang on the surface by axle, and crank is that the long end of an end is short; Semicircle iron sheet two ends respectively have one to be fixedly coupled head by holding screw; Adjustable link combination comprises positive and negative pitch thread axle, be enclosed within the linkage connector at positive and negative pitch thread axle two and be located at the adjusting nut at positive and negative pitch thread axle middle part; Pull bar is to be used for an end to be connected with lever, and the other end is connected with pedal; The other end of lever is connected with an end of adjustable link combination, and the other end of adjustable link combination is connected with a long end of crank; The short end of another of crank is connected with the connector of semicircle iron sheet one end; Semicircle iron sheet other end connector hangs on the motor by axle; It is to be fixed on the axle that the back side, middle part of lever is provided with light-operated switch and blade and blade, and blade and light-operated switch have certain angle setting; Brake rubber block is encircled brake rim, and brake rubber block is to be close to semicircle iron sheet inboard.
The beneficial effects of the utility model embody and to be: by structural design of the present utility model, utilize electric start and mechanical braking to combine, cushion brake with brake rubber block, can effectively avoid on the one hand causing burning out circuit board because of moment brake electric current is excessive; Can cushion brake speed greatly by brake rubber block on the other hand, handled easily makes that the motor on the industrial sewing machine is durable in use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail;
Fig. 1 changes schematic diagram clockwise for the brake rim of the utility model structure;
Fig. 2 changes schematic diagram counterclockwise for the brake rim of the utility model structure;
Wherein the name identification among the figure is as follows: 1 brake rim, the combination of 2 adjustable link, 3 blades, 4 pull bars, 5 connectors, 6 levers, 7 light-operated switches, 8 cranks, 9 connectors, 10 brake rubber blocks, 11 semicircle iron sheets, 12 connectors, 21 linkage connectors, 22 adjusting nuts, 23 positive and negative pitch thread axles, 24 linkage connectors.
The specific embodiment
As shown in Figure 1 and Figure 2, industrial sewing machine motor brake assembly mainly comprises adjustable link combination 2, lever 6, pull bar 4, crank 8, semicircle iron sheet 11, brake rubber block 10 and brake rim 1; Described lever 6 is to hang on the motor by axle; Crank 8 is to hang on the surface by axle, and crank 8 is that the long other end of an end is short; Semicircle iron sheet 11 two ends respectively have one to be fixedly coupled head (9,12) by holding screw; Adjustable link combination 2 comprises positive and negative pitch thread axle 23, be enclosed within the linkage connector (21,24) at positive and negative pitch thread axle 23 two and be located at the adjusting nut 22 at positive and negative pitch thread axle 23 middle parts; Pull bar 4 is to be used for an end to be connected with lever 6 by connector 5, and the other end is connected with pedal; The other end of lever 6 is connected with an end of adjustable link combination 2, and the other end of adjustable link combination 2 is connected with a long end of crank 8; The short end of another of crank 8 is connected with the connector 9 of semicircle iron sheet 11 1 ends; Semicircle iron sheet 11 other end connectors hang on the motor by axle; It is to be fixed on the axle that the back side, middle part of lever 6 is provided with light-operated switch 7 and blade 3 and blade 3, and blade 3 and light-operated switch 7 have certain angle setting; Brake rubber block 11 is encircled brake rim 1, and brake rubber block 10 is to be close to semicircle iron sheet 11 inboards;
Operation principle of the present utility model is: when motor stopped, brake rubber block 10 and brake rim 1 were to hug, and are in braking state; When pedal is stepped on downwards, pull bar 4 drives levers 6 toward drop-down, and the other end of lever 6 drives up top of adjustable link combination 2, and crank 8 is being followed motion and driven semicircle iron sheet 11 connectors (9,12), makes brake rubber block 10 leave brake rim 1.When pedal was stepped on downwards, the blade 3 at the lever 6 central shaft back sides also relied on light-operated switch 7 simultaneously, and at this moment motor begins to start; When pedal when upwarping, pull bar 4 drives lever 6 and up pushes up, the other end of lever 6 drives adjustable link combination 2 toward drop-down, crank 8 is being followed motion semicircle iron sheet 11 connectors of drive (9,12) makes brake rubber block 10 hold brake rim 1 tightly, motor is in halted state, when upwarping, the blade 3 at the lever 6 central shaft back sides also leaves light-operated switch 7 simultaneously, makes the motor disconnecting circuit at pedal;
Can adjust distance between brake rim 1 and the brake rubber block 10 by the adjusting nut 22 in the adjustable link combination 2;
In addition, brake rubber block 10 and brake rim 1 will have the certain distance just can starter, otherwise can damage motor.The distance that brake rubber block 10 and brake rim are 1 can be regulated according to the old and new employee's qualification.Motor uses when long-time, and brake rubber block 10 is understood some wearing and tearing, can make up 2 distances of regulating brake rubber block 10 and brake rim 1 by adjustable link, when certain limitation can not be regulated, should change brake rubber block 10.
Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, as the technical solution of the utility model being made amendment or being equal to replacement, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
