Abstract
The utility model discloses a gear shifter of gear grinders, which is mainly characterized in that the gear shifter is composed of a rocker arm, a connecting rod, a gear shifting frame, a dividing disc, etc. The automatic feeding of regrinding can be realized by using a gear shifting claw to poke the dividing disc. The utility model can realize the automatic feeding of saw blades with various defects, can avoid the manual operation, not only can improve the regrinding precision of the saw blades and reduce the consumption of the saw blades, but also can relieve the labor intensity of workers.
Description
The utility model relates to the apparatus for feeding that is used for workpiece on a kind of lathe, particularly the moving tooth device of circular saw bit profile of tooth grinding machine.
The hard alloy saw blade of industrial extensive use must adopt the profile of tooth grinding machine when making and repair, its significant feature is the profile of tooth of correct grinding saw blade.In profile of tooth grinding machine when work, promote the carbide alloy face of sawtooth one by one by being contained in moving tooth pawl on the swinging axle, realizes the reconditioning of sawtooth.The every swing of swinging axle once, the moving tooth pawl promptly moves a pitch of teeth, grinding machine can accurately be set the pitch of teeth of saw blade according to the saw blade number of teeth.This moving tooth mode of grinding machine can reach the purpose that accurately feeds for the complete saw blade of profile of tooth.Fracture carbide alloy sword sheet accident such as come off but in actual production, sawtooth takes place through regular meeting.At these positions, just can not realize moving with the automatic moving tooth that pitch of teeth feeds, can only manual operation.Grinding quality is difficult to assurance, but also can influence the reconditioning precision of whole saw blade.
The purpose of this utility model just provides a kind of device, guarantees still can realize when sawtooth is damaged accurately moving tooth automatically, to guarantee grinding quality.
To achieve these goals, the utility model discloses a kind of moving tooth device of profile of tooth grinding machine, this covering device is installed on the profile of tooth grinding machine, its main feature is that this device is made up of rocking arm, connecting rod, moving tooth frame and index dial; rocking arm is contained on the swinging axle of grinding machine, and the moving tooth frame links to each other with rocking arm by connecting rod, and index dial is contained on the main shaft of grinding machine; the tooth on the index dial is meshed with moving tooth pawl on the moving tooth frame, and the number of teeth of index dial is identical with the number of teeth of saw blade.Saw blade to be grinding is contained on the main shaft, saw blade is linked to each other with index dial with alignment pin.After starting grinding machine, swinging axle drives rocking arm, connecting rod pulling moving tooth frame, and the moving tooth pawl is promptly stirred index dial and is rotated a tooth, and saw blade also rotates a tooth thereupon, and emery wheel can carry out a reconditioning to sawtooth.So repeat, until the reconditioning of finishing whole sawtooth.
Adopt the utility model, owing to realized feeding automatically to the reparation of various defective saw blade, avoided manual operation, so not only improved the reconditioning precision of saw blade, increase the service life, reduce the consumption of saw blade, but also alleviated working strength of workers, have tangible economic benefit and social benefit.
Below in conjunction with accompanying drawing an embodiment of the present utility model is described in detail:
Fig. 1 Fig. 2 is a schematic diagram of the present utility model.
As seen from the figure, the utility model mainly contains rocking arm 1, connecting rod 2, moving tooth frame 3, index dial 4 etc.Rocking arm is contained on the swinging axle of grinding machine, and a guide groove is arranged on the rocking arm, and a slide block is housed in the groove, and connecting rod is contained on the slide block, and can be fixed with the nut on the slide block.The other end of connecting rod links to each other with the moving tooth frame.Mainly contain a moving tooth pawl on the moving tooth frame, being connected with the moving tooth frame with pin 6 also can be that axle rotates with the pin.On the moving tooth frame, also have an alignment pin 7 by moving tooth pawl bottom, make the moving tooth pawl can only folk prescription to rotation.Square shaft 8 on the moving tooth frame links to each other with main shaft, makes rocking arm, connecting rod, and the moving tooth frame is formed a rigid frame.Index dial is contained on the main shaft of grinding machine, is screwed, and one week of index dial cylindrical is processed with tooth, and the number of teeth is with consistent by the number of teeth of reconditioning saw blade.Will adjust whole device before operation, the tooth on the index dial is meshed with the moving tooth pawl, the nut of tightening then on the rocking arm slide block gets final product.Be contained in saw blade to be grinding on the main shaft during operation and, the locating hole consistent with saw blade arranged on the index dial, index dial and saw blade are fixed together, can not produce relative slip when the reconditioning with index dial to guarantee saw blade with alignment pin near index dial.Refill platen and twist good clamp nut.Start grinding machine, still set the motion of swinging axle according to the pitch of teeth of saw blade.Rocking arm is whenever upwards swung once, correspondingly moves upward with regard to drivening rod and moving tooth frame, and the moving tooth pawl is just stirred a tooth, and index dial just rotates counterclockwise an angle, and saw blade also rotates an angle thereupon, i.e. a tooth.When swinging axle did to reset motion, the moving tooth pawl resetted spring compression when the moving tooth pawl slips into next tooth position rear spring, and the moving tooth pawl is promptly locked index dial, and at this moment emery wheel moves downward, and finishes reconditioning work.When adopting this device, saw blade to the different numbers of teeth needs the different index dial of adapted, and it is identical for the number of teeth, the saw blade that diameter is different just need not changed index dial during reconditioning, if but do not adopt the utility model, the number of teeth is identical and saw blade that diameter is different, pitch of teeth is different, and pitch of teeth is not integer generally, so accurately set also difficulty relatively of pitch of teeth.This is an another advantage of the present utility model.
Claims (3)
1, a kind of moving tooth device of profile of tooth grinding machine, it is characterized in that this device is made up of rocking arm, connecting rod, moving tooth frame and index dial, rocking arm is contained on the swinging axle of grinding machine, and the moving tooth frame links to each other with rocking arm by connecting rod, index dial is contained on the main shaft of grinding machine, and the tooth on the index dial is meshed with the moving tooth pawl.
2, moving tooth device as claimed in claim 1 is characterized in that index dial has and waits to grind the identical number of teeth of saw blade.
