Abstract
The invention discloses a clamping and positioning device for machining a subway hook. The clamping and positioning device comprises an upper positioning block and a lower positioning block. One sides of upper and lower positioning blocks are rotatably connected, and the other sides of upper and lower positioning blocks are fixedly connected through a connecting member. The upper positioning block and the lower positioning block comprise concave portions matched with a limiting groove of the subway hook respectively, bottom widths of the concave portions are matched with the distance between roots of adjacent frustum structures on the subway hook, notch portions corresponding to inclined planes of the frustum structures are arranged on sides of upper and lower positioning blocks, and when upper and lower positioning blocks are locked together, a clamping cavity for clamping the limiting groove of the subway hook is defined between upper and lower positioning blocks. Compared with the original clamping mode, the clamping and positioning device has the advantages that accurate and stable clamping and positioning can be achieved, the operation is flexible and convenient, the production cost is reduced, and the working efficiency is improved.
Description
Technical field
The present invention relates to field of machining, relate in particular to a kind of clamping and positioning device for subway hook machining.
Background technology
Existing a kind of subway hook structure as shown in Figure 1, comprise main rod body 1, be arranged at intervals with some annular stop portions 2 to outer lug on this main rod body top external diameter, define the stopper slot 3 that can be used for fixing rubber between the adjacent limiting section, the cross section of annular stop portion 2 is the frustum structure.The side of frustum structure is inclined-plane 4.The right part of main rod body 1 is for needing mach bayonet socket 5.Because subway hook be the polymorphic structure of this forging, cause when its bayonet socket being carried out fine finishining and location, existing installation way can't be accurately, this subway of stable holding is linked up with.
Summary of the invention
At the problems referred to above, the invention provides a kind of clamping and positioning device for subway hook machining, to solve the problem of the clamping subway hook that installation way of the prior art can't be accurate, stable.
To achieve these goals, technical scheme of the present invention is as follows:
Be used for the clamping and positioning device of subway hook machining, it is characterized in that, comprise on one side be rotatably connected, another side passes through fixedly connected last locating piece and the following locating piece of connector; Described upper and lower locating piece include one with the suitable depressed part of subway hook stopper slot, distance between the root of the adjacent frustum structure on the bottom width of this depressed part and the subway hook is suitable, the side of upper and lower locating piece is provided with the notch part corresponding with the inclined-plane of frustum structure, when described upper and lower locating piece is locked together, define between the upper and lower locating piece for the clamping chamber that clamps subway hook stopper slot.
In the present invention, described depressed part comprises horizontal segment and the arc transition section that is arranged on the horizontal segment two ends, and the arc transition section is corresponding with the main rod body fillet of subway hook.
In the present invention, described one side of going up locating piece and following locating piece is rotatably connected by bearing pin, and another side connects by clamping screw.
The invention solves subway hook can't be accurately when fine finishining, the stable holding orientation problem, utilize the forging profile of subway hook, numerical control machining center is made the upper and lower locating piece of applying workpiece, utilize connecting pin and clamping screw to connect to form clamping and positioning device, subway is linked up with clamping, realized special-shaped workpiece accurately and fast, convenient location.Original relatively installation way, the present invention can be accurately, stable holding is located, and flexible and convenient operation reduces production costs, and increases work efficiency.
Characteristics of the present invention can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
