Abstract
The utility model discloses a clamping and positioning device used for machining a subway hook. The clamping and positioning device comprises an upper positioning block and a lower positioning block, one side of the upper positioning block is connected with one side of the lower positioning block in a rotatable mode, the other side of the upper positioning block is fixedly connected with the other side of the lower positioning block through a connection piece, the upper positioning block and the lower positioning block respectively comprise a concave part matched with a limiting groove of the subway hook, the width of the bottom of each concave part is in fit with the distance between the root portions of adjacent frustum structures on the subway hook, and the side face of the upper positioning block and the side face of the lower positioning block are respectively provided with a notch part corresponding to the slopes of the frustum structures. When the upper positioning block and the lower positioning block are locked together, a clamping cavity used for clamping the limiting groove of the subway hook is defined between the upper positioning block and the lower positioning block. Compared with a prior clamping mode, the clamping and positioning device can carry out clamping and positioning accurately and stably, is flexible and convenient to operate, reduces production cost and improves working efficiency.
Description
Technical field
The utility model relates to field of machining, relates 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 the annular stop section 2 of some outside projections 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 section 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.
The utility model content
For the problems referred to above, the utility model 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, the technical solution of the utility model is as follows:
Be used for the clamping and positioning device of subway hook machining, it is characterized in that, Yi Bian comprise be rotatably connected, upper locating piece and lower locating piece that another side is fixedly connected with by 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 utility model, 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 utility model, one side of described upper locating piece and lower locating piece is rotatably connected by bearing pin, and another side connects by clamping screw.
The utility model has solved 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.Relatively original installation way, the utility model energy is accurate, the stable holding location, and flexible and convenient operation reduces production costs, and increases work efficiency.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
