Abstract
The utility model discloses a punch with a steel ball. A steel ball is disposed at a symmetrical position at the upper end of a pin of the punch and connected with the lower end of a constant-force bar, a spring is arranged outside the constant-force bar disposed inside the spring, the bottom of the spring is connected with the bottom of the constant-force bar, the upper portion of the spring is connected to a rear socket base, a hollow anvil is arranged at a convex ring of the rear socket base, a recess portion of the hollow anvil is cylindrical, the diameter of the recess portion is slightly larger than that of the upper portion of the constant-force bar, the upper portion of the hollow anvil is connected with a percussion spring, and the upper portion of the percussion spring is connected with the upper portion of the rear socket. Force transmitted by the constant-force bar can be more concentrated by the aid of the steel ball, a stress point is in the middle of the punch so that percussion force is transmitted to the pin stably, punching of the punch is more stable, and punching precision is improved.
Description
Technical field
The utility model relates to sample and dashes, and relates in particular to a kind of steel ball sample that has and dashes.
Background technology
Sample dash be very the widely used hardware ﹠ tools of technical staff it, especially use morely in technical fields such as machinery, building, carpenter, building materials, but existing sample is towards unreasonable structure, precision is not high, uses inconvenience, has a strong impact on work quality.Disclose a kind of sample at present and dashed, publication numbers 200320101202.2, this sample dashes the wobbler action generation impulsive force by hollow hammer, impulsive force is delivered to decides the power rod, gets to drift at last, goes out anchor point, and is simple in structure, can reach certain precision.But the power rod lower part of deciding that this sample dashes directly is connected with drift, and be that the plane connects, like this, drift is stressed concentrated when decide the power bastinade and hitting drift, and can produce wobbler action, influence the stability that drift hits, often make striking point produce dislocation, influence positioning accuracy, and this sample is unreasonable towards handle designs, do not meet the ergonomics requirement, hold sample towards the time palm be difficult to the control dynamics, further have influence on attack precision.
The utility model content
The technical problems to be solved in the utility model provide a kind of easy to use, reasonable in design, get the high sample of precision ready and dash.
The utility model is achieved like this, comprise drift, the taper front sleeve, back sleeve, the handle sleeve, one through hole is arranged in the middle of the taper front sleeve, drift is set in the through hole, the taper front sleeve is connected with the back sleeve, back sleeve is connected with the handle sleeve, it is characterized in that described drift upper end symmetric position is provided with a steel ball, steel ball again with decide power rod lower end and be connected, decide power rod outside and be provided with a spring, decide the power rod and be arranged at spring inner, the spring bottom is connected bottom deciding the power rod, spring top is connected on the sleeve base of back, back sleeve base bulge loop place is provided with a hollow recessed hammer, and recessed partial shape is cylindrical in the hollow recessed hammer, and its diameter is bigger slightly than deciding power rod top diameter, hollow recessed hammer top connects impact spring, and its top connects the back upper cartridge.
Described handle sleeve comprises base and holds tube, holds the outside one-tenth of tube tetrahedron, and the bottom is taper, is socketed on sleeve outside, back, and back sleeve integral body is entangled.
After adopting this technological improvement, because steel ball can make and decide the power that power rod transmits and focus on a bit, and stress point is in the centre position that sample dashes, make impulsive force stable be delivered to drift, it is more stable that drift is got ready, improves and get precision ready.Because sample meets ergonomics towards that design of handle sleeve, and palm is easy to control the dynamics that sample dashes that is applied to like this, further improve and get precision ready again.
Description of drawings
Fig. 1 is the utility model cross-sectional view
In the drawings, 1, drift 2, steel ball 3, spring 4, recess 5, hollow recessed hammer 6, handle sleeve 7, taper front sleeve 8, decide power rod 9, back sleeve 10, impact spring 61, base 62, hold tube
The specific embodiment
As shown in Figure 1, the utility model is realized by following embodiment, comprise drift 1, taper front sleeve 7, back sleeve 9, handle sleeve 6, one through hole is arranged in the middle of the taper front sleeve 7, drift 1 is set in the through hole, taper front sleeve 7 is connected with back sleeve 9, back sleeve 9 is connected with handle sleeve 6, it is characterized in that described drift 1 upper end symmetric position is provided with a steel ball 2, steel ball 2 again with decide power rod 8 lower ends and be connected, decide excellent 8 outsides of power and be provided with a spring 3, decide power rod 8 and be arranged at spring 3 inside, spring 3 bottoms are connected with deciding 8 ones at the power rod end, and spring 3 tops are connected on sleeve 9 bases of back, and back sleeve 9 base bulge loop places are provided with a hollow recessed hammer 5, recessed partial shape is cylindrical in the hollow recessed hammer 5, its diameter is bigger slightly than deciding power rod 8 top diameters, and hollow recessed hammer 5 tops connect impact spring 10, and its top connects sleeve 9 tops, back.Described handle sleeve 6 comprises base 61 and holds tube 62, holds tube 62 outside one-tenth tetrahedrons, and the bottom is taper, is socketed on sleeve 9 outsides, back, and back sleeve 9 integral body are entangled.
Certainly; the spheroid that sample can also select for use other materials to make towards interior steel ball substitutes; the holding tube part and also can be designed to other geometries of handle sleeve; the tetrahedron design is only selected in this case for use; above-mentioned the utility model most preferred embodiment that is; all samples that relates to similar structures dash, and all drop in the protection domain of the present utility model.
Claims (2)
1. one kind has the steel ball sample and dashes, comprise drift, the taper front sleeve, back sleeve, the handle sleeve, one through hole is arranged in the middle of the taper front sleeve, drift is set in the through hole, the taper front sleeve is connected with the back sleeve, back sleeve is connected with the handle sleeve, it is characterized in that described drift upper end symmetric position is provided with a steel ball, steel ball again with decide power rod lower end and be connected, decide power rod outside and be provided with a spring, decide the power rod and be arranged at spring inner, the spring bottom is connected bottom deciding the power rod, spring top is connected on the sleeve base of back, back sleeve base bulge loop place is provided with a hollow recessed hammer, and recessed partial shape is cylindrical in the hollow recessed hammer, and its diameter is bigger slightly than deciding power rod top diameter, hollow recessed hammer top connects impact spring, and its top connects the back upper cartridge.
