Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

As shown in figs. 1 to 6, the chisel includes: in embodiment provided by the utility model

Shell 1, shell 1 from two can with upper casing and lower casing form, it is possible to understand that in order to seal, upper casing and lower casing Between should be equipped with gasket；The first guiding device 2 in shell 1；And the cam mechanism 3 in shell 1, cam machine Structure 3 includes: two and is fixed together, and cam face (i.e. cam face 311 and cam face 321) it is just opposite first Edge cam 31 and second end face cam 32, the side opposite with cam face of first end face cam 31 is equipped with to be connected with power device The attachment device 33 connect, second end face cam 32 are a hollow cam；The hollow portion 322 that may pass through second end face cam 32, with The cam face of both ends face cam is engaged, with the driven member 34 for driving chisel ontology 4 (such as perching knife) to move, driven member 34 are equipped with and can cooperate with the first guiding device 2, so that the second guiding device 341 that driven member 34 moves in a straight line.

In the present embodiment, two edge cams rotations are driven by power device, and in the first guiding device 2 and the Under the mating reaction of two guiding devices 341, driven member 34 is made to do straight reciprocating motion, and then it is past to drive chisel ontology 4 to do straight line Multiple movement taps chisel without worker and can be completed and root out work to ceramic tile, bottom plate, reduces the labor intensity of worker, mention High working efficiency.

It should be understood that in the present embodiment, the cam face of two edge cams should be adapted to, i.e., after cam mechanism assembling Guarantee that the spacing between two cam faces is equal everywhere.In addition, lubricating oil is added into shell for convenience, offered on shell Oilhole, and it is equipped with the capping that oilhole can be sealed, such as rubber stopper.

As shown in figure 3, cam mechanism 3 further includes the spacing block 35 between two edge cams, three removably connects It is connected together, in the present embodiment, spacing block 35 is a hollow cylindrical piece, and the size of hollow space should ensure that cylindrical piece will not The movement of driven member 4 is interfered.

The connection of three may is that two edge cams are respectively equipped at least two through-holes, and spacing block 35 is equipped with and leads to The corresponding threaded hole in hole, three are fastened by bolts in together.In order to keep connection effect more preferable, these through-hole numbers are more It is a, and be equably arranged on the edge cam where it.The connection of three is also possible to: two edge cams and spacing block 35 It is equipped with corresponding through-hole, three is anchored on together by bolt and corresponding nut, in order to keep connection effect more preferable, this A little through-holes are equably arranged on the components where it.

It is understood that the effect of spacing block 35 be to keep the assembling of cam mechanism simpler, when assembling, spacing block 35 is adjacent to The end face of two cams, length should make the gap between the cam face of both ends face cam that be able to cooperate with driven member 34, i.e. cam When rotation, cam face can be to driven member applied force, and under the action of the first guiding device 2 and the second guiding device 341 Driven member is set to do straight reciprocating motion.

In another embodiment provided by the utility model, the location and installation of both ends face cam can also only pass through bolt and spiral shell Female cooperation and realize, the utility model does not illustrate excessively herein.

In the present embodiment, it is one in push rod lateral projections that driven member 34, which is at a push rod, with both ends of the surface cam engagement, Cylinder 342, cylinder 342 can be the straight pin (push rod be equipped with corresponding hole) squeezed on push rod, be also possible to and push rod It is integrally formed.

As shown in Figures 2 and 3, for the ease of manufacturing, in embodiment provided by the utility model, the first guiding dress 2 are set as a guide groove, guide groove, which can be, passes through casting integrated molding with shell；Second guiding device 341 be and guide groove phase The limited post of adaptation, limited post can be by casting with driven member (i.e. push rod) be integrally formed, be also possible to by elder generation from It drills on moving part and squeezes into the modes such as pin again and be made.In order to keep guide effect more preferable, in embodiment provided by the utility model, It is additionally provided with guide sleeve 7 compatible with push rod.

In the present embodiment, chisel further includes at least two bearings for supporting the cam mechanism, it is preferred that uses two Bearing, i.e. bearing 51 and bearing 52 in Fig. 4, bearing can be separately mounted on two edge cams, at this time two end faces Cam is equipped with bearing installation position, and specifically in the present embodiment, cam installation position is disposed far from one end of cam face；When So, on the other side, the corresponding bearing block of bearing should be equipped in shell 1.

In the present embodiment, in order to manufacture and easy for installation, chisel ontology 4 is integrated with driven member 34 (that is, push rod) Molding structure.If can be therebetween certainly in order to be conveniently replaceable chisel ontology through dismountable side such as pin connection Formula is attached, and don't explain too much here for the utility model.

In embodiment provided by the utility model, power device can be the rotary device such as electric hand drill, even Tipping is set to a connecting rod.It skids in order to prevent, the stronger connecting rod for clamping electric hand drill is equipped with flat position, preferred to connect Bar is equipped with multiple evenly arranged flat positions, and the quantity of flat position can be 6.

In addition, as shown in figure 4, corresponding location hole is respectively equipped on two edge cams in order to easy to assembly, at this Two groups of location holes are used in embodiment, the positioning pin 6 being adapted to through-hole can be used first to be positioned when assembling.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
