Abstract
The invention relates to an indexing device for tooth punching on a circular saw blade substrate. An index plate is fixed on an indexing rotary core shaft; a plurality of indexing teeth are distributed on the outer edge of the index plate uniformly; a compaction plate and a compaction nut are arranged on the indexing rotary core shaft; an indexing needle is matched with the index plate; the indexing needle is arranged in an indexing needle base; the indexing needle is connected with an indexing needle pull rod; a spring is sleeved on the indexing needle pull rod; and a deflector rod is connected with the indexing needle pull rod and a support rod. In the indexing device, the positioning form of the index plate is changed into the conical surface positioning by the horizontal indexing needle from original vertical bolt positioning; the index plate is in a fluted disc form rather than the original pin hole form, namely the indexing teeth which are in the same number as the teeth on the saw blade substrate and are consistent with the indexing needle in shape are machined on the outer circle of the index plate. When the indexing device is used, the conical surface of the indexing needle is jointed with the bevel surface of the index plate tightly under the pressure of the spring on the indexing needle, so that the aim of accurate positioning is filled and the defect that the positioning of bolt indexing is inaccurate due to gaps is overcome; and the rotary indexing positioning of each tooth on the circumference is realized by the rotary core shaft.
Description
Technical field
The invention belongs to the hardware stamping mould applications, relate to circular saw blade substrate towards the used indexing means of tooth.
Background technology
The tooth Profile Machining of the circular saw blade substrate of prior art mainly contains processing modes such as punching press, laser cutting, line cutting, milling, and laser cutting and line cutting adopt numerical control program to control the even distribution of each tooth on circumference, and processing cost is higher, limited efficiency system; Milling Process adopts rotary table to control the even distribution of each tooth, and indexing operation efficient is lower; Punch process adopts and then adopts special-purpose index dial, can reach the uniform purpose of calibration by shirtsleeve operation, punching press and operating efficiency are all higher, and cost comparatively speaking, will be low a lot, so generally adopt punch process to make the tooth portion of saw bit matrix.
In the method for operating of existing circular saw blade substrate toothed portion degree processing, generally adopt latch and pin-and-hole index dial to cooperatively interact and locate, realize even calibration.But this bolt-type indexing mechanism is after the use through long-time or multifrequency time, and latch and pin-and-hole can produce latch and diminish owing to often produce friction, and it is big that pin-and-hole becomes, thereby occurs that the gap appears in latch and phenomenon that location when influencing calibration is forbidden.The location will definitely not cause that the tooth of saw bit matrix is long inconsistent, will correspondingly have influence on the client in the cutter head not prison welding of back operation or the phenomenon of misalignment.Particularly concerning the laser automatic welding device that the tooth calibration is had relatively high expectations, tooth calibration inequality can have a strong impact on the welding quality of product, the saw blade of especially severe even can not use.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of at circular saw blade substrate in tooth calibration process, can adapt to long-time, multifrequency and use indexing mechanism and precision can not be affected inferiorly, and the circular saw blade substrate of the actual use of handled easily person is towards the tooth indexing means.
Purpose provided by the invention is achieved in that a kind of circular saw blade substrate is towards the tooth indexing means, index dial is fixed on the calibration rotation mandrel, a plurality of calibration teeth evenly distribute on the index dial outer rim, also be provided with pressure strip and clamp nut on the calibration rotation mandrel, the calibration pin matches with index dial, and the calibration pin is installed in the calibration needle stand, and the calibration pin is connected with calibration pin pull bar, be set with spring on calibration pin pull bar, driving lever is connected with support bar with calibration pin pull bar.
Circular saw blade substrate provided by the present invention is towards the tooth indexing means, change index dial into horizontal calibration pin conical surface location by original vertical latch location, index dial changes toothed disc type into by original pin-and-hole formula simultaneously, be the processing and the calibration tooth of saw bit matrix number of teeth same number on the index dial cylindrical, profile of tooth is consistent with the shape of calibration pin, is 60 ° of conical surfaces.By the pressure of spring, the conical surface of calibration pin is close on the tooth conical surface of index dial during use, reaches the purpose of accurate positioning, solve the latch calibration because of the inaccurate defective in location, gap to the calibration pin; Realize the rotation calibration location of each tooth on the circumference by the rotation mandrel.
Compared with prior art, the present invention has following advantage:
1, owing to adopt the fluted disc calibration, the positioning accuracy when having improved towards the tooth calibration has effectively guaranteed the tooth calibration index of saw bit matrix.
2, adopt the fluted disc calibration, strengthened the wearability of calibration pin, and calibration pin and index dial can not influence the machining accuracy of calibration after wearing and tearing mutually.
3, easy and simple to handle, improved the operating efficiency that adds man-hour.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a side-looking structural representation of the present invention.
Fig. 2 is a plan structure schematic diagram of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, index dial 7 of the present invention is fixed on the calibration rotation mandrel 5, a plurality of calibration teeth 14 evenly distribute on the index dial outer rim, also be provided with pressure strip 6 and clamp nut 4 on the calibration rotation mandrel 5, calibration pin 8 matches with index dial 7, and calibration pin 8 is installed in the calibration needle stand 11, and calibration pin 8 is connected with calibration pin pull bar 9, be set with spring 10 on the calibration pin pull bar 9, driving lever 12 is connected with support bar 13 with calibration pin pull bar 9.
The profile of tooth of calibration tooth 14 is identical with the shape of calibration pin 8.
Engineering process of the present invention is as follows: at first circular saw blade substrate 3 is fixed on the index dial 7 of indexing means, with pressure strip 6 and nut 4 it is compressed, saw bit matrix 3 and index dial 7 can not be moved mutually.Then, with the right hand driving lever 12 is buttressed, by finishing punching press, after punching press once towards mark of mouth mould 1 with towards tooth punch 2, driving lever 12 is pulled back, rotate index dial 7 with left hand, make index dial 7 rotate a tooth, unclamp the driving lever 12 of the right hand then, make the effect of calibration pin 8 by spring 10, be returned in the calibration tooth 14 of index dial 7 and go, realize location for the second time, and then second tooth of punching press.So repeatable operation can be finished the tooth that dashes of a slice saw bit matrix and process.
