Abstract
The utility model discloses a grinder automatic reciprocal feeder. The technical scheme is that a stepless speed regulation motor regulates speed via a change gear set; the output shaft of the speed change mechanism is connected with a swing pin mechanism; the front end of the swing pin of the swing pin mechanism is provided with a swing pin slider in a swing pin chute; two ends of the swing pin chute are provided with sliders respectively connected with a guide rail; a front and a back driving line are provided in a driving device and are respectively connected with the front and the back sides of the swing pin chute, via a front pulley or a back pulley; two ends of each driving line are fixed on a branch chain and a grinder worktable; thereby realizing automatic reciprocal motion of the grinder worktable. The grinder automatic reciprocal feeder is characterized in that in same stroke, the volume of the swing pin mechanism is reduced by 50%; the feeder realizes stepless speed regulation and automatic reciprocation, to improve efficiency by 5 times and improve machining precision by at least one time; the power consumption is 1/3 of common hydraulic device; the feeder has stable operation, easy operation, high safety and reliability.
Description
Technical field
The utility model relates to a kind of feed device, especially grinding machine feed device.
Background technology
Grinding machine, particularly small-sized Grinder bench reciprocating feed adds man-hour, most hand gears that adopt, labour intensity is big; Minority adopts hydraulic pressure or pneumatic means, its complex structure, and the cost height, reversing impact power is big, can not even running, influence machining accuracy.
Summary of the invention
In order to overcome the above deficiency of prior art, the utility model provide a kind of can stepless speed regulation again can automatic reciprocating feed, and operate steadily, the automatic reciprocating feed device of grinding machine that transmission efficiency is high.
The purpose of this utility model is to realize like this, it comprises motor, gear, output shaft, fork and drive unit etc., its technical scheme is: stepless speed-regulating motor is by the gear shift speed change, the output shaft of gear is connected with swing-bar mechanism, fork front end in the described swing-bar mechanism is provided with the fork slide block, the fork slide block is arranged in the fork chute and drives the fork chute in the process that fork moves in a circle and seesaws, the two ends of fork chute are provided with left and right slide block, and left and right slide block is connected with guide rail respectively and can slides on this guide rail; Two of front and back in the described drive unit drive rope is connected the fork chute respectively by a pulley both sides, front and back, and the two ends that drive rope are fixed on side chain and the Grinder bench.
Owing to adopt described swing-bar mechanism and drive unit, add and adopt the soft drive rope in the drive unit, make to the utlity model has following beneficial effect:
One, it is rational in infrastructure, in same stroke, the more original device of volume of swing-bar mechanism is dwindled more than 50%.
Two, Grinder bench stepless speed regulation, and reciprocating stroke is adjustable; Automatic reciprocating, efficient improves more than 5 times than prior art, and machining accuracy improves more than 1 grade.
Three, power consumption is few, and cost is low, and power consumption only is 1/3 of a common hydraulic means.
Four, the soft drive rope is alleviated the impulsive force in the running, operates steadily, and makes workbench more steady.
Five, easy to operate, safe and reliable.

Among the figure: 1-motor, 2-gear, 21-output shaft, 3-fork, 31-fork slide block, 4-fork chute, 5-slide block, 6-guide rail, 7-forerunner's running rope, 8-rear-guard running rope, 9-pulley, 10-side chain, 11-ratchet, 12-spring, 13-body, 14-bolt hole.
The specific embodiment
As shown in Figure 1 and Figure 2, the automatic reciprocating feed device of the utility model grinding machine comprises motor, gear, output shaft, fork and drive unit etc.Its technical scheme is: stepless speed-regulating motor 1 is by gear shift 2 speed changes, the output shaft 21 of gear is connected with the fork 3 of swing-bar mechanism, fork 3 front ends in the described swing-bar mechanism are provided with fork slide block 31, fork slide block 31 is arranged in fork chute 4 and drives the fork chute in the process that fork moves in a circle and seesaws, the two ends of fork chute 4 are provided with left slider, right slide block 5, and left and right slide block is connected with guide rail 6 respectively and can slides on this guide rail; Two of front and back in the described drive unit drive rope 7,8 is connected fork chute 4 respectively by a pulley 9 both sides, front and back, and the two ends that drive rope are fixed on side chain 10 and the Grinder bench.Driving rope in the drive unit is a flexible strand.
During work, stepless speed-regulating motor 1 operation, by gear shift 2 speed changes, 21 connections of gear output shaft and the fork 3 that drives in the swing-bar mechanism move, the fork slide block 31 of fork 3 front ends promotes fork chute 4 and makes the front and back reciprocally swinging along guide rail 6, front wheel, the rear wheel 9 of both sides, fork chute 4 front and back connection simultaneously also are being driven and are seesawing, last front and back driving rope 7,8 drives Grinder bench respectively by the front and back pulley and advances, retreats, and realizes that Grinder bench automatically moves back and forth.
As improvement of the present utility model, drive rope 7,8 and be provided with ratchet 11 and spring 12, drive the tension force size of rope before and after regulating thus.
As further improvement of the utility model, described swing-bar mechanism places in the body 13, and this body 13 is fixed in the Grinder bench below by bolt by the bolt hole on the body 14, and it is easy to operate, and is safe and reliable.
