Abstract
The utility model relates to a multifunctional fixture. The fixture comprises a clamp tray having an axial through hole. The periphery of the clamp tray is provided with three radial screw holes communicated with the through hole and a bolt is connected in each radial screw hole. A protecting jacket is sleeved on a screw rod part outside the clamp tray. Through the utility model, the operations of clamping and holding the circular shaft tools or parts can be flexibly realized. The tools or parts are prevented from sliding during the operations by using a three-point positioning principle so the utility model has the advantages of high positioning property, flexible clamp, convenience, time saving, simple structure, difficulty to damage and low manufacturing cost. In actual applications, the utility model not only can be used for clamping tools or parts but also can be used as a wrench for the daily life so the multifunctional fixture of the utility model has better practical applicability.
Description
Technical field
The utility model relates to a kind of anchor clamps, specifically refers to the anchor clamps of a kind of energy clamping cutter or workpiece.
Background technology
When the processing parts aperture, because of the existence of machining accuracy, some part often needs to process earlier aperture slightly less than normal, and then cuts with scissors the mutually suitable aperture of size with the reamer of same diameter.As in the plastic mould male model benevolence, on this male model benevolence, need to have the centre hole that shuttles back and forth for thimble, requirement to this centre hole is: thimble can be realized within it moving back and forth swimmingly, but too big fit clearance can not be arranged between the two, otherwise in the injection molded process, the plastic cement melt will flow out from this gap bigger than normal, and forms burr, makes the product that is injection molded into form defective products.When this centre hole of processing,, but all exist the machining accuracy problem at present with processing modes such as depth drill processing or milling machine borings.In order to overcome above-mentioned precision defective, the aperture that normally processes earlier is less than normal apertures, and then uses with the reamer of normal apertures same diameter and revise.Can be for the male model benevolence of large mold and since its can't be on machine tool normal clamping, thereby to realize that it is difficulty comparatively that the lathe fraising is revised, so often need manual the correction.
The existing commonly used manual practice of revising is: use the tapping spanner, clamp chucking reamer such as locking pliers or the reamer that grinds with thimble voluntarily carry out the manual correction aperture.But when the above-mentioned reamer of clamping, it is square or angular all requiring the shape at clamping position, otherwise clamping weak effect, skid easily behind the clamping, be unfavorable for the location, thereby the scope of application of anchor clamps can be subjected to certain restriction, and with tapping spanner or locking pliers clamping reamer underaction, the conversion elastic space is little, and has and take the big drawback of peripheral space in the operating process.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of clamping that is easy to is provided, and polarization is good, and multi-functional clamp simple in structure, applied widely.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this multi-functional clamp includes the clamping dish of tape spool to through hole, periphery at this clamping dish has three radially screws that connect with described through hole, is connected with bolt in each described radially screw.
In order to improve the comfort level that hand grips, in the bar portion of the bolt that is positioned at the described clamping dish outside, can also be arranged with protective jacket, utilize this protective jacket can prevent finger wearing and tearing skin or foaming after twisting back and forth for a long time.
Described three radially screw preferably evenly distribute along described clamping dish periphery, make workpiece or instrument stressed evenly, clamp reliably guaranteeing.
Compared with prior art, adopt the utility model can flexible transformation ground to realize the clamping of circular shaft class instrument or part and operation such as hold, and utilize the three-point fix principle can prevent from operating process, to occur the skidding of instrument or part effectively, thereby the utility model positioning performance, clamping is flexible, easy, save time, and it is simple in structure, not fragile, cost of manufacture is low, both can be used for clamping tool or part in actual applications, the spanner that can be used as again in the daily life uses, so have better practicability.
Description of drawings
Fig. 1 is the front view of the utility model embodiment;
Fig. 2 is the A-A line cutaway view (removing instrument) among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, this multi-functional clamp includes the clamping dish 1 of tape spool to through hole 11, periphery at this clamping dish is evenly distributed with three radially screws that connect with through hole, and each radially is connected with bolt 2 in the screw, is positioned in the bar portion of bolt in the clamping dish outside also to be arranged with protective jacket 3.
When making, the external diameter of clamping dish 1 can be set according to individual hand size, and hole size can be determined concrete size according to the routine work needs.Protective jacket adopts soft plastic material to make, and can protect finger, the comfort level when improving operation.
During use, instrument 4 (as reamer) end is stretched in the through hole 11 of clamping dish, rotated three bolts 2 respectively, three bolts 2 are moved, toward through hole 11 center positions till tightly blocking instrument 4.This moment, present embodiment was used as the spanner use, can hold the clamping dish, circumferential wrenching bolt, and the drive instrument rotates and manually operation such as fraising of realization.When needing to take out reamer, as long as the reverse rotation bolt makes each bolt get final product away from the through hole center.
If clamping is the part to be processed of circular shaft class in the above-mentioned clamping dish, then the clamping dish of the good part of clamping being fixed on the lathe (as use the flat-nose pliers clamping on the milling machine) carries out lathe fraising correction.Obviously, as long as the workpiece in the through hole internal diameter allowed band all can pass through this clamping dish clamping, the adjustable extent of anchor clamps is big, and clamping is flexible, and is easy, saves time.
Claims (3)
1. a multi-functional clamp is characterized in that including the clamping dish (1) of tape spool to through hole (11), has three radially screws that connect with described through hole (11) at the periphery of this clamping dish (1), is connected with bolt (2) in each described radially screw.
2. multi-functional clamp according to claim 1 is characterized in that: be positioned in the bar portion of bolt (2) in described clamping dish (1) outside and be arranged with protective jacket (3).
