Abstract

The utility model relates to a frock clamp, in particular to an internal-tensioning three-pin grinding clamp for an internal tooth gear. The internal-tensioning three-pin grinding clamp for the internal tooth gear comprises a clamp body with a taper shank, a centering tensioning cone, a force application screw, springs and positioning pins. The centering tensioning cone is installed in the middle of the clamp body with the taper shank, the springs are installed in the centering tensioning cone and respectively connected with the centering tensioning cone and the clamp body with the taper shank in a matched mode, and the force application screw is installed in the front end of the centering tensioning cone. A plurality of positioning pin holes are formed in the end face of the clamp body with the taper shank, and the positioning pins are installed in the positioning pin holes. The internal-tensioning three-pin grinding clamp of the internal tooth gear is simple in structure, the cone-shaped clamp body is conveniently installed through matched with a machine tool, a workpiece is easy to assemble and disassemble rapidly, auxiliary time is short, errors are reduced due to one-time clamping, precision is improved, working efficiency is high, and meanwhile cost is saved.

Description

Internal expansion type internal-gear three pin clamps
Technical field
The utility model relates to a kind of frock clamp, refers to especially a kind of internal expansion type internal-gear three pin clamps.
Background technology
The fixture of prior art, during its workpiece loading and unloading, operation is comparatively complicated, needs repeatedly clamping repeatedly, and non-cutting time is longer, and easily jig error occurs, causes the accidents such as precision is not up to standard, has affected the efficient of processing, has increased production cost.
The utility model content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, the spy provides a kind of internal expansion type internal-gear three pin clamps, effectively solve prior art clamping complex procedures, needed repeatedly clamping repeatedly, the lower defective of error and precision easily occurred.
Two, technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of internal expansion type internal-gear three pin clamps, includes band taper shank clamp body, centering tensioning cone, application of force screw, spring and location needle pin; Above-mentioned centering tensioning cone is arranged on middle part in band taper shank clamp body, and above-mentioned spring fitting is connected with centering tensioning cone and band taper shank clamp body respectively in centering tensioning cone; Above-mentioned application of force screw is arranged in centering tensioning cone front end; Above-mentioned band taper shank clamp body end face has some location pin hole, and above-mentioned location needle pin is arranged in the pin hole of location.
As optimization, above-mentioned location needle pin has 3, evenly is arranged in the pin hole of location.
As optimization, above-mentionedly subtract the stress hole with having on the taper shank clamp body be used to what weaken stress.
Three, the beneficial effects of the utility model
Internal expansion type internal-gear three pin clamps of the present utility model are simple in structure, and tapered clamp specifically coordinates with lathe installs more for convenience, the workpiece loading and unloading simple and fast, non-cutting time is short, and error that clamped one time is less has improved precision, operating efficiency is higher, provides cost savings simultaneously.
Description of drawings
Fig. 1 is the structure chart of internal expansion type internal-gear three pin clamps of the present utility model.
Fig. 2 is the side view of internal expansion type internal-gear three pin clamps of the present utility model.
In figure, 1 is band taper shank clamp body, and 2 are centering tensioning cone, and 3 be application of force screw, and 4 be spring, and 5 are the location needle pin, and 6 is to locate pin hole, and 7 for subtracting the stress hole.
The specific embodiment
Below in conjunction with accompanying drawing, internal expansion type internal-gear three pin clamps of the present utility model are described further:
Embodiment: as shown in Fig. 1 to 2, internal expansion type internal-gear three pin clamps of the present utility model include band taper shank clamp body 1, centering tensioning cone 2, application of force screw 3, spring 4 and location needle pin 5; Above-mentioned centering tensioning cone 2 is arranged on band taper shank clamp body 1 interior middle part, and above-mentioned spring 4 is arranged in centering tensioning cone 2, is connected with centering tensioning cone 2 and band taper shank clamp body 1 respectively; Above-mentioned application of force screw 3 is arranged in centering tensioning cone 2 front ends; Above-mentioned band taper shank clamp body 1 end face has some location pin hole 6, and above-mentioned location needle pin 5 is arranged in the pin hole 6 of location.
Above-mentioned location needle pin 5 has 3, evenly is arranged in the pin hole 6 of location.
Above-mentionedly subtract stress hole 7 with having on taper shank clamp body 1 be used to what weaken counter stress, can reduce the stress with taper shank clamp body 1 when clamping workpiece, extend its life-span.
When the internal expansion type internal-gear three pin clamps of the present embodiment use, only need workpiece is inserted, tightening application of force screw 3 can make band taper shank clamp body 1 spreading drive three radially synchronous outer clamping work pieces that move of location needle pin 5, after machining, unclamp application of force screw 3, to be with taper shank clamp body 1 to release under the elastic force effect of spring 4, band taper shank clamp body 1 reinstatement attitude is taken out workpiece and is got final product.
Internal expansion type internal-gear three pin clamps of the present utility model are simple in structure, and tapered clamp specifically coordinates with lathe installs more for convenience, the workpiece loading and unloading simple and fast, non-cutting time is short, and error that clamped one time is less has improved precision, operating efficiency is higher, provides cost savings simultaneously.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
