Abstract
The utility model provides an integrated two-way jack catch for obverse and reverse sides which is the improvement of a lathe jack catch. The front end of the jack catch is made with a stepped catch foot, the side surface is made with a channel like the Chinese character 'gong', and the back surface is made with a thread; the sectional plane of each thread is made into a* shape formed by crossing an obverse segment vortex line and a reverse segment vortex line. The thread can be matched with the vortex line channel on a vortex line disc regardless of the obverse installation or the reverse installation of the jack catch on a chuck; the jack catch is served as an obverse catch when the jack catch is installed in an obverse mode, and the jack catch is served as a reverse catch when the jack catch is installed in a reverse mode, the two-way purpose for obverse and reverse sides is realized with easy use, and the cost is economized.
Description
Technical field
The utility model relates to turned part, particularly to the improvement of claw.
Background technology
The claw, particularly three-jaw that use on lathe at present are to be shaped on stairstepping pawl pin at the corpus unguis front end, and the side is opened and is shaped on " worker " word groove, and the back side is shaped on the spiral shell tooth.Wherein the groove on " worker " word groove and the chuck is connected in order to stationary jaw, and the spiral shell tooth cooperates with the vortex filament dish of setting in the chuck, and the umbrella tooth is made at the vortex filament dish back side, with the conelet tooth engagement that is embedded on the chuck.Rotate the conelet tooth during use, drive the vortex filament dish and rotate,, make the claw clamping or loosen by of the drive that cooperates of vortex filament groove with the spiral shell tooth.
Lathe needs to use positive pawl or anti-pawl when the processing different workpieces, present way is that the positive and negative two kinds of claws of preparation are standby, replaces when needed and uses.Because positive and negative two kinds of claws can not be general, cause and use inconvenience.
Summary of the invention
The utility model purpose is to provide the claw of reversible, uses with convenient.
Scheme of the present utility model is: monoblock type reversible claw, be shaped on stairstepping pawl pin at the claw front end, and the side is opened and is shaped on " worker " word groove, and the back side is shaped on the spiral shell tooth, and the cross section of each spiral shell tooth is all made by positive and negative two sections vortex filaments and is intersected and form
The shape shape.
The utility model has the advantages that: owing to each spiral shell tooth is all made to be intersected by positive and negative two sections vortex filaments and formed
The shape shape, no matter claw formal dress or anti-dress on chuck, its spiral shell tooth all can cooperate with the vortex filament groove on the vortex filament dish, uses as positive pawl during the claw formal dress like this, as anti-pawl use, has realized the purpose of reversible during anti-the dress, and is easy to use, the saving cost.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is the utility model three-dimensional structure diagram.
Fig. 2 is the utility model lateral plan.
When Fig. 3 is the utility model as positive pawl, with the connection diagram of chuck.
Fig. 4 is that the utility model is during as anti-pawl, with the connection diagram of chuck.
Mark among the figure: 1 claw, 1-1 pawl pin wherein, 1-2 " worker " word groove, 1-3 spiral shell tooth; 2 chucks; 3 conelet teeth; 4 vortex filament dishes; 5 end caps.
The specific embodiment
As depicted in figs. 1 and 2, monoblock type reversible claw is shaped on stairstepping pawl pin 1-1 at claw 1 front end, and the side is opened and is shaped on " worker " word groove 1-2, and the back side is shaped on spiral shell tooth 1-3, and each spiral shell tooth 1-3 all makes crossing by positive and negative two sections vortex filaments and olive shape that form, promptly
The shape shape.
Owing to each spiral shell tooth is all made to be intersected by positive and negative two sections vortex filaments and is formed
The shape shape, no matter claw formal dress or anti-dress on chuck, its spiral shell tooth all can cooperate with the vortex filament groove on the vortex filament dish.
When using as positive pawl, as shown in Figure 3, claw 1 formal dress is in the groove of chuck 2, its spiral shell tooth cooperates with the vortex filament dish 4 of setting in the chuck 2, rotates conelet tooth 3 during use, drives vortex filament dish 4 and rotates, by of the cooperate drive of vortex filament groove, claw 1 is clamped or loosen with the spiral shell tooth.
When using as anti-pawl, as shown in Figure 4, claw 1 is counter to be contained in the groove of chuck 2, equally, its spiral shell tooth cooperates with the vortex filament dish 4 of setting in the chuck 2, rotates conelet tooth 3 during use, drive vortex filament dish 4 and rotate,, make claw 1 clamping or loosen by of the drive that cooperates of vortex filament groove with the spiral shell tooth.
During use, with claw 1 formal dress or counter being contained on the chuck 2, can realize the purpose of reversible as required, make things convenient for use, and save cost.
