Abstract
The utility model provides a spring machine pitch fine adjustment mechanism which drives a fine adjustment screw to adjust pitch through rotation of a stepping motor. The spring machine pitch fine adjustment mechanism comprises a front panel, a rear panel, a servo motor, a ball screw, an adjusting device and a pitch rod, wherein a connection plate is fixed on the pitch rod, and the connection plate is connected with the ball screw. The adjusting device comprises a stepping motor, a guide rail, a fine adjustment screw, a thread tube, a shifting rod, a left-handed nut and a right-handed nut, wherein the thread tube has a reversed thread, the left-handed nut is sleeved on one side of the thread tube, the right-handed nut is sleeved on the other side of the thread tube, and the fine adjustment screw is connected with the shifting rod. The spring machine pitch fine adjustment mechanism uses the fine adjustment screw to drive the shifting rod of the thread tube to swing up and down, the thread tube can swing to drive the left-handed nut and the right-handed nut to move left and right, and the automatic adjustment function for different pitches in a spring processing process can be achieved. The spring machine pitch fine adjustment mechanism is accurate to control, capable of solving the problem that pitches change due to the fact that steel wires bend, and strong in actual applicability.
Description
Technical field
The utility model relates to the spring manufacturing equipment, particularly coiling machine pitch fine adjustment mechanism.
Background technology
In coiling machine, the pitch adjustment is a very important link.Existing regulation by pitch technology is that the pitch bar is fixed by connecting plate and feed screw nut, moves forward and backward to complete with driven by servomotor ball screw drive feed screw nut.In the processed springs process, the pitch of spring can change along with the distortion direction of steel wire, and the spring height of making is inconsistent.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of energy by stepper motor
rotate the coiling machine pitch fine adjustment mechanism that drives fine setting screw rod adjusting joint distance, for this reason, the utility model is by the following technical solutions: it comprises front panel, rear board, be positioned at the outer servomotor of rear board, be connected with the servomotor output shaft and penetrate ball screw between front panel and rear board, adjusting device between front panel and rear board and the pitch bar that passes front panel and be connected with adjusting device, be fixed with connecting plate on described pitch bar, described connecting plate connects ball screw, described adjusting device comprises stepper motor, the guide rail that is used for the installation stepper motor and fixes with front panel and rear board, the fine setting screw rod that is connected by universal joint with the output shaft of stepper motor, be enclosed within the screwed pipe on the feed screw nut, be located on the screwed pipe lateral surface poke rod and left-handed nut and right-handed nut, described screwed pipe both sides have reverse thread, screwed pipe one side cover has the left-handed nut of fixing with the feed screw nut, the opposite side cover has the right-handed nut fixing with connecting plate, described fine setting screw rod is connected with poke rod.
On the basis of adopting above technical scheme, the utility model can also adopt following scheme:
Described poke rod is rotating poke rod, and described poke rod has the screw thread that matches with the fine setting screw flight, and poke rod is stirred up and down by the rotation of fine setting screw rod.
Described stepper motor is located by the bearing that is enclosed within on guide rail, and moves with screwed pipe.
Owing to having adopted the technical solution of the utility model, the utility model is swung up and down by the poke rod that the fine setting screw rod drives on screwed pipe, swing by screwed pipe drives left-handed nut and the right-handed nut moves left and right, and realizes the inconsistent automatic regulating function of the pitch of spring in process.The utility model is controlled accurately, has avoided the problem that changes due to the crooked pitch that causes of steel wire, and practical application is strong.

The specific embodiment
With reference to accompanying drawing.
The utility model comprises front panel 14, rear board 3, the servomotor outside rear board 31, is connected with servomotor 1 output shaft and penetrates ball screw 5, the adjusting device between front panel and rear board between front panel and rear board and the pitch bar 16 that passes front panel and be connected with adjusting device, be fixed with connecting plate 17 on described pitch bar 16, described connecting plate 17 connects ball screw 5, and the output shaft of described servomotor is by the rotation of gear driven ball screw.The fine setting screw rod 7 that described adjusting device comprises stepper motor 12, stepper motor and the guide rail 13 that is connected with rear board with front panel be used for to be installed, be connected by universal joint with the output shaft of stepper motor, be enclosed within screwed pipe 8 on feed screw nut 6, be located on screwed pipe 8 lateral surfaces poke rod 20 and left-handed nut 4 and right-handed nut 15.
Described screwed pipe both sides have reverse thread, screwed pipe one side cover has the left-handed nut 4 of fixing with the feed screw nut, the opposite side cover has the right-handed nut 15 fixing with connecting plate, and described screwed pipe is provided with poke rod 20 on lateral surface, and described fine setting screw rod 7 is connected with poke rod 20.
Described poke rod is rotating poke rod 20, and has the screw thread that matches with the screw thread of fine setting screw rod 7, rotation by stepper motor 12, poke rod 20 is stirred up and down by the rotation of fine setting screw rod 7, rotation by screwed pipe 8 drives left-handed nut 4 and right-handed nut 15 leaves simultaneously or close moving forward and backward, and realizes the inconsistent automatic regulating function of the pitch of spring in process.Servomotor 1 described in the utility model can only drive ball screw 5 and carry out coarse adjustment, when needing fine setting, completes by stepper motor 12.When stepper motor 12 was finely tuned, described left-handed nut 4 was fixing with feed screw nut 6, made right-handed nut 15 drive connecting plate 17 with the left and right displacement of speed adjusting joint apart from bar 16.
Described stepper motor is by being enclosed within bearing 10 location on guide rail 13, and described bearing 10 is linear bearing, and moves with screwed pipe.Stepper motor follows the feed screw nut to move forward and backward on guide rail by linear bearing.
