Abstract
The utility model relates to a dual-purpose tool for disassembling taper shanks, which is used for disassembling the 0-6 taper shanks with a tang in the Spindle for a machine tool and is used as a hammer. The utility model is characterized in that a spring (3) and a wedge head (5) are arranged between a hammer block (2) and a cover (4), the hammer block (2) and the cover (4) are arranged on both ends of a casing (2), the head of the wedge head (5) extends out of the casing (1) through a hole arranged on the cover (4), the bottom surface of the utility model is a lengthened slant surface, and both sides of the utility model are conical surfaces which are increased toward the tail part. The utility model can replace all specifications of wedges in the JB3482-83 wedge using standard for taper shanks with a tang. The utility model has the advantages of simple structure, high safety and convenient operation.
Description
The utility model relates to a kind of device that unloads taper shank in the machine tool chief axis, especially unloads a kind of instrument that 0 to No. 6 band tang taper shank and double as hammer use.
At present, the known instrument that unloads taper shank in the machine tool chief axis is JB3482-83 " a tang taper shank wedge ", because how not general again the specification of wedge is in the standard, so keeping is used all inconvenient, owing to also must knock when using, take user's both hands, after taper shank is dropped with hammer, often damage platen face, anchor clamps, part to be processed or self, also dangerous to the user.
The purpose of this utility model provides a kind of instrument, and it can not only make things convenient for, safety is unloaded taper shank, but also the double as hammer uses.
The purpose of this utility model is achieved in that and is sequentially set with hammer piece, spring, wedge head and lid in shell, the wedge head stretches out head outside the shell by the hole that covers, the head bottom surface is the inclined-plane of a lengthening, and two sides are the conical surface that increases to afterbody, and hammer piece one end exceeds the shell end face or flushes.When the wedge head is inserted unload the hole of taper shank on the machine tool chief axis after, promote shell and advance fast, shell can drive the afterbody that resistance that the hammer piece overcomes spring impinges upon the wedge head makes taper shank loosening, thereby reaches the purpose of unloading taper shank.According to GB1443-85 " pad self-locking circular cone and tolerance " standard, the tang size of each number taper shank is all inequality, cause the hole dimension that unloads taper shank on the machine tool chief axis also different thus, in order to unload all taper shanks in the standard, except that the wedge head portion chamfer length that extended, and two sides are designed to the conical surface that increases to afterbody, can make the wedge head portion sectional dimension can be corresponding like this with all taper shank tang sizes, also can with machine tool chief axis on to unload the hole dimension of taper shank corresponding.
Owing to adopt such scheme, 0 in the standard of not only unloading easily and safely is to No. 6 taper shanks, but also the double as hammer uses.The utility model part is few, and is simple in structure.
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a longitudinal sectional drawing of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Among Fig. 1: 1. shell 2. hammer pieces 3. springs 4. cover 5. wedge heads
In the drawings, the two ends of shell (1) are respectively equipped with hammer piece (2) and lid (4), and spring (3) and wedge head (5) are housed between the two.Wedge head (5) head stretches out outside the shell (1) by the hole on the lid (4), and its head bottom surface is the inclined-plane of a lengthening, and the oblique angle is generally 8 degree, and the starting point on inclined-plane is of a size of 2 millimeters, and full-size is 19 to 23 millimeters, preferably gets 21 millimeters.The head two sides are the conical surface that increases to afterbody, and cone angle can preferably be got 4 degree between 2.5 to 5 degree, and the microcephaly between the conical surface is of a size of 2.5 to 3 millimeters, and major part is of a size of 15 to 17 millimeters.The elastic force of spring (3) is advisable with the weight that is slightly larger than wedge head (5), its pitch should guarantee to hammer into shape piece (2) and wedge head (5) when contacting, each encloses not also not together, and for certain impact velocity is arranged, the length of spring (3) in shell (1) is between 50 to 100 millimeters.The weight of hammer piece (2) can be chosen between 400 to 500 grams, and one end should exceed shell (1) end face or flush.
Claims (4)
1, a kind of dual tool that unloads band tang taper shank in the lathe main shaft, between the hammer piece (2) and lid (4) at shell (1) two ends, spring (3) and wedge head (5) are housed, wedge head (5) head stretches out outside the shell (1) by the hole on the lid (4), the bottom surface of its head is an inclined-plane, it is characterized in that: the bottom surface of wedge head (5) head is the inclined-plane of a lengthening, and two sides are the conical surface that increases to afterbody, and hammer piece (2) one end faces exceed shell (1) end face or flush.
2, instrument according to claim 1, the full-size that it is characterized in that wedge head (5) head bottom surface is between 19 to 23 millimeters, and optimum size is 21 millimeters.
3, according to claim 1 and 2 described instruments, it is characterized in that wedge head (5) head two sides cone angle is 2.5 to 5 degree, the best is 4 degree.
4, instrument according to claim 1 is characterized in that the microcephaly between wedge head (5) the head conical surface is of a size of 2.5 to 3 millimeters, and major part is of a size of 15 to 17 millimeters.
