The specific embodiment
Below only with embodiment the enforcement state that the utility model is possible being described, so is not the category in order to the desire protection of restriction the utility model institute, chats bright in advance.
Please refer to Fig. 1 and Fig. 2, the utility model provides a kind of percussion tool head 1, and can supply to be installed in pneumatic tool 2 or similar can provide in the instrument of rotary power, driven by this instrument and rotates, and can further outwards export the rotary power with impact effect.
Please refer to Fig. 2 to Fig. 4, this percussion tool head 1 includes two impact blocks 11, one group of rotation section, two latches 13 and an axle 14.
Please refer to Fig. 4 to Fig. 6; Aforesaid impact block 11 includes a transmission ring 111 and an axostylus axostyle 112; This transmission ring 111 has an inner peripheral surface and an outer peripheral face, and this inner peripheral surface encloses structure has a perforation 113, and this perforation 113 is a non-circular hole; Define an axial direction with this perforation 113, this outer peripheral face is formed with a bank portion 114.This axostylus axostyle 112 extends protrusion from this outer peripheral face; Make this axostylus axostyle 112 and this transmission ring 111 be shaped to one, that is the solid memder that is formed in one of this axostylus axostyle 112 and this transmission ring 111, this axostylus axostyle 112 and this bank portion 114 be positioned at this impact block 11 away from both sides; This axostylus axostyle 112 is parallel to the axial direction that is defined by perforation 113; Preferable, axostylus axostyle 112 greater than the length of transmission ring 111 on axial direction, can make axostylus axostyle 112 protrude from transmission ring 111 both side surface in the length on the axial direction.
Please refer to Fig. 2 to Fig. 4 again, structure is enclosed in this rotation section has an accommodation space, in more detail; This rotation section comprises a body 121 and a lid 122, and this body 121 generally is tubular and goes out accommodation space in wherein enclosing structure, and this body is inboard and can form two symmetrical groups barricade 123 and the position groove 124 in the middle of barricade; Can supply the opening of two impact blocks 11 via tubular body 121 is placed in the accommodation space, be adjacent to be arranged in the accommodation space, and the axostylus axostyle 112 of two impact blocks is resisted against respectively in the groove 124 of both sides; Two impact blocks 11 can be swung around axostylus axostyle 112 separately; Wherein, two impact blocks 11 are answered setting opposite each other, that is; Wherein the axostylus axostyle of an impact block is resisted against a wherein groove; The axostylus axostyle of another impact block then is resisted against another groove, in the utility model preferred embodiment, because axostylus axostyle 112 protrudes from transmission ring 111 both sides; Axostylus axostyle 112 with two impact blocks in the time of can avoiding assembling is resisted against in the same groove 124, and makes the axostylus axostyle 112 of this impact block respectively be located in the bank portion 114 of adjacent impact block partly; This lid 122 is to be covered on this body 121; And be butted on lid 122 with a fastener 125 button; Avoid lid 122 and impact block 11 outwards to drop, this lid 122 is with body 121 and be formed with corresponding axis hole 126, in addition; This lid 122 also can cooperate the shape of body barricade 123, and local or be located in the accommodation space fully.
These axle 14 1 ends are formed with a working head 141; The other end is to be located at the rotation section rotationally and to be located at accommodation space, is arranged in the axis hole 126 of rotation section, and this axle 14 also is arranged in the perforation 113 of each impact block; Furtherly; The part that this axle 14 is arranged in each perforation 113 is formed with the protuberance 142 of corresponding perforation 113 shapes, can when impact block 11 rotates, make impact block 11 intermittently clash into axle 14, drives axle and rotates; Because impact block 11 is two rightabout settings, axle 14 is formed with two rightabout protuberances 142 too.
Utilize said apparatus, as shown in Figure 1, the utility model can supply to be assembled in pneumatic tool 2 or the similar means; Supply air tool rotor 21 to drive and rotate; And when rotating, utilizing impact block 11 intermittently to clash into axle 14, the rotary power that makes axle can further utilize working head output to have impact effect supplies user's branch sleeve or other workpiece; In order to assembling or dismounting screw tightening, or drive other workpiece rotations.
Hold above-mentionedly, the rotation section in the utility model has the body 121 of tubular, and can further form the groove 124 and barricade 123 of symmetry in the rotation section; Has better simply structure complexity; Be easy to make, simultaneously, supply 11 of the impact blocks of assembling to have axostylus axostyle 112; The time need not consider the mounting direction of impact block in assembling, be easy to the characteristics of assembling and have.And when second impact block 11 of assembling, 112 of the axostylus axostyles of evagination can prevent that two impact blocks 11 are assembled as equidirectional, have the function of use that prevents assembly defect.
In addition, because the axostylus axostyle 112 of impact block is formed as one with transmission ring 111 in the utility model, make the wherein thickness increase of a side of impact block 11; Under the situation that structural strength allows; Can inner peripheral surface and perforation 113 be enlarged towards a side of axostylus axostyle 112, and the material and the weight of cutting down impact block 11, at this moment; Because it is a side that is positioned near axle 14 that impact block is cut down the part of material; The whole rotary inertia of impact tool heads influences little, and can under the situation of minimum degree affect impulsive force, alleviate the weight of percussion tool head, and has splendid result of use.
Secondly, after the perforation in the transmission ring 111 enlarged, the size of axle 14 and protuberance 142 thereof also can correspondingly increase, and the contact area in the time of can improving impact block 11 with axle 14 bumps improves transmission efficiency, and can effectively increase the output of rotary power.
Moreover; Because the weight of percussion tool head reduces; Also can increase material in other positions of percussion tool head; Make the material that increases part be positioned at the position of percussion tool head periphery, and can under the situation of same weight, improve the rotary inertia of percussion tool head, and then increase the output of rotary power away from axle.
In addition; Because promptly have axostylus axostyle in the impact block, impact block can directly be arranged in the rotation section, can remove the gap between transmission ring and the axostylus axostyle; And then reduce vibrations and the abrasion between each part; Can kinetic energy be directly delivered to impact block when the rotation section is rotated, reduce the power consume of transmitting between part and the part, and then can improve transmission efficiency and service life.
Sum up above embodiment; The utility model provides a kind of percussion tool head, has the characteristics of making, assembling of being easy to, and can prevent the generation of wrong assembling situation; Can reduce simultaneously the weight of percussion tool head again; Improving outputting rotary power, further improve transmission efficiency and service life, is the proof that has progressive effect in fact.
