Abstract
The utility model discloses a quick clamping tool for an internal grinding machine for grinding diameter type products. The quick clamping tool comprises a ring-shaped base body, and a ring-shaped clamping body arranged on one end surface of the base body, wherein the clamping body and the base body are coaxial, and a notch is formed in the side surface of the clamping body in the axial direction; mounting holes are correspondingly formed in two sides of the notch of the clamping body. The quick clamping tool is simple in structure, safe and reliable, can realize product batch processing only through one-step clamping and concentricity calibration, not only can greatly improve the processing efficiency, but also can ensure the product processing quality.
Description
Technical field
The utility model relates to a kind of clamping device, relates to specifically a kind of diameter series products and grinds with internal grinder fast clamp instrument.
Background technology
At all kinds of precision dies, plant equipment, on automation equipment, often can use a lot of as: accurate demoulding guide pin bushing, without the straight body guide pin bushing of oil supply self-moistening type, sleeve, the accurate cylinder of hollow, large ejector sleeve, ball jacket in ball bearing, the accurate spare and accessory parts such as graphite sleeve, in inner-diameter portion whose, usually can select according to the requirement of different precision grades as: boring puts in place, fraising puts in place, bore and grind and put in place, the CNC finish turning puts in place, the requirements such as grinding puts in place, the field put in place in grinding, common most internal grinder production firm all can configure the mechanical type three-jaw, oil pressure type three-jaw, the external diameter that air-pressure type three-jaw three class method of clamping are clamped product carries out attrition process to internal diameter.Through long-term test, finding between this three all has some bad general character: the one, and during clamping, product is not easy to proofread and correct concentricity, and the overlong time of wasting while proofreading and correct concentricity, remove to strike three-jaw or product and make three-jaw and product concentric; The 2nd, when resetting is carried out producing in batches, the concentricity of product is inaccurate again, and going of repeating again proofreaied and correct concentricity and caused the time of proofreading and correct concentricity also longer than the time of grinding; The 3rd, find not in place will being reprocessed as product after grinding, because of pre-allowance seldom, proofreading and correct the time that concentricity wastes can be longer.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of diameter series products to grind with internal grinder fast clamp instrument, simple in structure, safe and reliable, clamped one time gets final product, and does not need to proofread and correct concentricity, guarantee machining accuracy simultaneously, more greatly promoted working (machining) efficiency.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of diameter series products grinds with internal grinder fast clamp instrument, comprise the base body of annular and be located at one end face and the clamping body that be annular of this base body, this clamping body and described base body coaxial line, and the side of described clamping body is provided with a gap slot along its axis direction, separately the gap slot dual-side correspondence at described clamping body is provided with installing hole.
As further improvement of the utility model, the internal diameter of described clamping body is identical with the internal diameter of described base body, and the external diameter of described clamping body is less than the external diameter of described base body.
The beneficial effects of the utility model are: simple in structure, safe and reliable, and only need to carry out clamped one time and concentricity and proofread and correct, can realize the batch machining of product, not only greatly promote working (machining) efficiency, and guaranteed product processing quality.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
By reference to the accompanying drawings, make the following instructions:
1---base body 2---clamping body
3---gap slot 4---installing hole
The specific embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, a kind of diameter series products grinds with internal grinder fast clamp instrument, comprise the base body 1 of annular and be located at one end face and the clamping body 2 that be annular of this base body, this clamping body and described base body coaxial line, and the side of described clamping body is provided with a gap slot along its axis direction 3, separately the gap slot dual-side correspondence at described clamping body is provided with installing hole 4.When the diameter series products is ground, first by this clamping device clamping on mechanical type three-jaw, oil pressure type three-jaw or air-pressure type three-jaw etc., and concentricity, the perpendicularity of adjustment base body and three-jaw, then three-jaw is locked, finally the external diameter of product to be processed is coordinated the internal diameter lock hanging of clamping body to get final product in this clamping device, so just guaranteed the concentricity of external diameter and the clamping device internal diameter of product, can realize the attrition process of product, while dismantling after processing, only the lock screw on clamping body installing hole need to be unclamped to dismounting and get final product.Batch machining for the product more than two, only need the internal diameter of this clamping device is blown clean, product is packed into to lock and get final product, do not need again to proofread and correct concentricity, reach once and proofread and correct, the effect that can put things right once and for all, saved the time with the three-jaw handling greatly, the working (machining) efficiency promoted has guaranteed crudy simultaneously.
Preferably, the internal diameter of described clamping body is identical with the internal diameter of described base body, and the external diameter of described clamping body is less than the external diameter of described base body.
Claims (2)
1. a diameter series products grinds with internal grinder fast clamp instrument, it is characterized in that: comprise the base body (1) of annular and be located at one end face and the clamping body that be annular (2) of this base body, this clamping body and described base body coaxial line, and the side of described clamping body is provided with a gap slot along its axis direction (3), separately the gap slot dual-side correspondence at described clamping body is provided with installing hole (4).
2. diameter series products according to claim 1 grinds with internal grinder fast clamp instrument, and it is characterized in that: the internal diameter of described clamping body is identical with the internal diameter of described base body, and the external diameter of described clamping body is less than the external diameter of described base body.
