Abstract
The utility model discloses an inner hole positioning clamping device, comprising a positioning pin and four claws. One end of the cylindrical positioning pin is provided with four chutes equally allocated in radial directions; the bottoms of the four claws are provided with sliding rails corresponding to the chutes; tops of the four claws are provided with a stopping device used for preventing the claws from slipping off from the positioning pin; and a shape and a size of the positioning pin are matched with clamped workpieces. The inner hole positioning clamping device is simple in structure, easy to install, use and manufacture, and has strong manufacturability and a long service lifetime.
Description
Technical field
The utility model relates to the Machining Technology field, particularly relates to a kind of endoporus positioning clamping device.
Background technology
In machining, need to confirm the tram of workpiece with respect to cutter, squint to avoid the workpiece work in-process; The equipment of accomplishing this effect promptly is a jig; Location and clamping are the main functions of anchor clamps, and locating surface commonly used has plane, cylindrical, endoporus etc., and it is a kind of installation way of often using that the endoporus location clamps; Generally realize that with centering or centering machine scroll chuck or spring ringfeder are two kinds of the most frequently used forms.
Scroll chuck clamping workpiece (seeing Fig. 1-1 and Fig. 1-2) mainly is applicable to slewing parts processing, and centering precision is good, and shortcoming is a complex structure, needs specialized factory to make, and is difficult in the anchor clamps of processing profiled complex class part, use.
Spring ringfeder clamping workpiece (seeing Fig. 2-1 and Fig. 2-2) both had been suitable for slewing parts processing, also can in processing profiled misconduct part processing, clamp with the endoporus location, and positioning accuracy is high; Shortcoming is that the ringfeder material requirements is high, and heat treatment is complicated, the manufacturing process trouble; Service life is short, and clamping force is little.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of endoporus positioning clamping device is provided.
The technical solution of the utility model is following:
A kind of endoporus positioning clamping device; Be characterized in that this device comprises alignment pin and four claws, described alignment pin is cylindric, and an end of this alignment pin has four chutes of radially dividing equally; The bottom of described four claws is provided with and the corresponding slide rail of this chute; Top at described four claws is provided with retention device, makes claw can not skid off alignment pin, and the shape and size and the caught workpiece of said alignment pin are suitable.
Described alignment pin and described claw can adopt different materials, make respectively.
Compared with prior art, technique effect of the present invention is following:
Because alignment pin and four claws adopt absolute construction, elder generation locatees afterwards and clamps, and simple in structure being convenient to installed and used.Can adopt different materials separately to make good manufacturability, long service life during manufacturing.
Description of drawings
Fig. 1-1, Fig. 1-2 are the structural representations of scroll chuck in the prior art.
Fig. 2-1, Fig. 2-the 2nd, the structural representation that the prior art medi-spring rises.
Fig. 3 is the structural representation of the utility model endoporus positioning clamping device.
Fig. 4 is the front view of the utility model endoporus positioning clamping device.
Fig. 5 is an A-A alignment cutaway view among Fig. 4.
Fig. 6 is the side view among Fig. 4.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, but should limit the protection domain of the utility model with this.
See also Fig. 3, Fig. 3 is the structural representation of the utility model endoporus positioning clamping device.As shown in the figure, a kind of endoporus positioning clamping device, this device comprise alignment pin 1 and four claws 2; Described alignment pin 1 is cylindric; One end of this alignment pin 1 has four chutes of radially dividing equally 5, and the bottom of described four claws is provided with and the corresponding slide rail 4 of this chute, is provided with retention device 3 at the top of described four claws; Make claw 2 can not skid off alignment pin 1, the shape and size and the caught workpiece of said alignment pin 1 are suitable.Described alignment pin and described claw adopt different materials, make respectively.
Show that through using the utility model endoporus positioning clamping device is simple in structure, to be convenient to install and use that positioning accuracy is high, make easy, good manufacturability, long service life.
