Abstract
The utility model discloses a disconnect-type chuck that is used for hot coil spring to roll up system, the chuck center has the through-hole, and the chuck comprises central tube structure and outlying disc structure, and tube structure and the coaxial and tube structure's of disc structure axial length are greater than the axial length of disc structure, and the round recess has been seted up around tube structure in the disc structure, and the separating ring cover is in tube structure and imbeds the recess. The boss part of the whole chuck is changed into a mode of boss and boss ring, which is equivalent to inlaying the boss ring on the boss of the clamping material (the boss ring and the boss are in transition fit and can rotate). The connection mode between chuck and the chuck seat is still for the welding, forms a whole with the chuck seat in other words, need not change whole chuck during the change, only change the boss ring can. Therefore, the novel rotary table can rotate at any time in the use process, reduces abrasion, prolongs the service life, and solves the problems that the replacement is frequent, a special person is needed for the replacement, and the replacement time is long.
Description
Technical Field
The utility model relates to a chuck structure of spring coiling machine.
Background
The main tool for coiling the hot coil spring comprises a mandrel, a chuck seat and a clamping jaw. The coiling process of the hot coil spring comprises the following steps: one end of the heated spring material is placed at the front end of the clamping jaw and is lapped on the cylindrical surface of the central protruding platform of the chuck, the spring material is clamped on the protruding platform of the chuck in the figure 2 by the clamping jaw, the chuck and the mandrel synchronously rotate, and the spring material is wound on the mandrel through the profiling to form a spring shape. The original chuck is of an integral structure and has the following problems: 1. the material clamping part of the lug boss of the chuck is very easy to wear in a hot state (the temperature of a spring material is 900-1000 ℃), the service life of the chuck is about 3 days, and the chuck is frequently replaced; 2. the connection mode between chuck and the chuck seat is the welding, must use burning torch cutting welding seam when changing the chuck, then with new chuck welding on the chuck seat, needs the special messenger to operate, and the change time is longer, once needs 1 hour approximately. 3. The whole chuck has the disadvantages of complicated processing procedure, long time and high processing cost.
Disclosure of Invention
The utility model discloses to the problem that is difficult for changing behind the protruding platform wearing and tearing in the middle of the chuck, provide a easily change unstable disconnect-type structure of wearing and tearing.
The technical scheme of the utility model is that:
the utility model provides a disconnect-type chuck for hot coil spring system of rolling up, the chuck center has the through-hole, and the chuck comprises central tube structure and outlying disc structure, and tube structure and disc structure are coaxial and tube structure's axial length is greater than disc structure's axial length, and the disc is structural has seted up the round recess around tube structure, and the separating ring cover is on tube structure and imbeds the recess.
The through hole in the center of the cylinder structure has taper.
The disc structure is provided with a through groove along the radial direction.
The disc structure and the cylinder structure are integrated.
Hook-shaped claws are arranged in the through grooves, the middle parts of the claws are hinged on the mounting shaft, the tail ends of the claws are inserted into the through holes of the cylinder structure, and the front ends of the claws are opposite to the side surfaces of the separating rings.
The separating chuck is arranged on a chuck seat of the spring coiling machine, and the mounting shafts of the clamping jaws are fixed on the side surface of the chuck seat.
The invention has the beneficial effects that:
the boss part of the whole chuck is changed into a mode of boss and boss ring, which is equivalent to inlaying the boss ring on the boss of the clamping material (the boss ring and the boss are in transition fit and can rotate). The connection mode between chuck and the chuck seat is still for the welding, forms a whole with the chuck seat in other words, need not change whole chuck during the change, only change the boss ring can. Therefore, the novel rotary table can rotate at any time in the use process, reduces abrasion, prolongs the service life, and solves the problems that replacement is frequent, special persons are needed for replacement, and the replacement time is long. Meanwhile, only the boss ring needs to be processed, the processing procedure is greatly simplified, and the problems of long processing time and high cost are solved.

FIG. 1 is a schematic diagram of the working principle of a coil coiling machine.
Fig. 2 is a front view of the improved chuck structure.
FIG. 3: a cross-sectional view of the chuck.
FIG. 4: the structure of the chuck after the clamping jaws are installed on the chuck is shown schematically.
Detailed Description
Example 1:
as shown in fig. 1, the power mechanism and the mandrel withdrawing mechanism are respectively arranged on the left side and the right side of the spring coiling machine, the profiling mold with a spiral structure is fixedly arranged below the spring coiling machine, the chuck is arranged on the inner side of the power mechanism, the mandrel is arranged on the mandrel withdrawing mechanism and can move left and right, the matching hole and the boss structure of the mandrel are arranged in the center of the chuck, when the spring is coiled, a steel bar in a high-temperature state is inserted into the middle of the profiling mold and the chuck, the mandrel and the chuck rotate together after being matched, and the steel bar is coiled into a spring around the mandrel under the action of the profiling mold.
Referring to fig. 2, the chuck has a through hole in the center, and is composed of a central cylinder structure and a peripheral disc structure, wherein the disc structure and the cylinder structure are integrated. As shown in fig. 3, the cylindrical structure and the disc structure are coaxial, the axial length of the cylindrical structure is greater than that of the disc structure, a circle of groove is formed in the disc structure around the cylindrical structure, and the separating ring is sleeved on the cylindrical structure and embedded into the groove. A through groove is formed in the disc structure along the radial direction, a hook-shaped clamping jaw is arranged in the through groove, the middle of the clamping jaw is hinged to the mounting shaft, the tail end of the clamping jaw is inserted into a through hole of the cylinder structure, and the front end of the clamping jaw faces the side face of the separating ring. The jaws can rotate around the mounting shaft in the middle. The separating chuck is arranged on a chuck seat at the front end of the power mechanism of the spring coiling machine, and the mounting shafts of the clamping jaws are fixed on the side surface of the chuck seat.
The through hole in the center of the cylinder structure has taper. The one end of spring material that will heat is put the conical head of jack catch and separation ring middle dabber tip and is inserted in the bell mouth of chuck and the terminal of roof pressure jack catch, and the jack catch front end rotates because terminal atress, blocks the spring material on the separation ring of chuck, chuck and dabber synchronous revolution, and the spring material forms the spring shape through profiling winding to the dabber.
Various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
Those not described in detail in this specification are within the skill of the art.
