Abstract
The utility model gives the coupling assembling that a kind of wood drill bit coordinates percussion drill, it comprises connecting rod and wood drill chuck, described connecting rod comprises rear portion first body of rod, the position limiting convex ring at middle part and second body of rod of front portion, first body of rod has the keyway coordinated with percussion drill chuck, second body of rod has external screw thread; Described wood drill collet rear has installing hole, the installing hole of wood drill chuck and the second body of rod threaded engagement.First body of rod of connecting rod is arranged in the percussion drill chuck of percussion drill, wood drill bit is arranged in wood drill chuck, percussion drill drives wood drill bit synchronous rotary, and then bore operation can be carried out to wooden workpiece, this coupling assembling realizes percussion drill both can fabrication of concrete workpiece, can process wooden workpiece again; Wood drill chuck and connecting rod threaded engagement are convenient to fractionation and are carried, and the position limiting convex ring of connecting rod contacts with wood drill chuck rear end face, increase stability during bore operation, are convenient for carrying, promote operating efficiency.
Description
Technical field
The utility model relates to the coupling assembling that a kind of wood drill bit coordinates percussion drill.
Background technology
There is percussion drill chuck percussion drill front portion, and percussion drill chuck is provided with chopping bit, and it mainly relies on to rotate and impact and carries out bore operation to concrete workpiece; Electric hand drill coordinates wood drill bit mainly to carry out bore operation to wooden workpiece, but percussion drill does not mate mutually with wood drill bit, in construction operation, often need to carry out bore operation to concrete workpiece and wooden workpiece, use percussion drill and electric hand drill two kinds of electric drills, not Portable belt, and reduce operating efficiency.
Wood drill chuck is a kind of built-up jig that wood drill bit uses, wood drill collet front has retaining thread hole, and retaining thread hole coordinates with wood drill bit rear threads, with fixing wood drill bit, there is installing hole at the rear portion of wood drill chuck, but wood drill chuck cannot make wood drill bit and percussion drill with the use of.
Utility model content
Technical problem to be solved in the utility model be to provide a kind ofly to be convenient for carrying, promote operating efficiency wood drill bit coordinate the coupling assembling of percussion drill.
For solving the problems of the technologies described above, the utility model provides the coupling assembling that a kind of wood drill bit coordinates percussion drill, it comprises connecting rod and wood drill chuck, described connecting rod comprises rear portion first body of rod, the position limiting convex ring at middle part and second body of rod of front portion, first body of rod has the keyway coordinated with percussion drill chuck, second body of rod has external screw thread; Described wood drill collet rear has installing hole, the installing hole of wood drill chuck and the second body of rod threaded engagement.
After adopting such structure, first body of rod of connecting rod is arranged in the percussion drill chuck of percussion drill, wood drill bit is arranged in wood drill chuck, percussion drill drives wood drill bit synchronous rotary, and then percussion drill can be used to carry out bore operation to wooden workpiece, this coupling assembling realizes percussion drill both can fabrication of concrete workpiece, can process again the object of wooden workpiece; Wood drill chuck and connecting rod threaded engagement are convenient to fractionation and are carried, and the position limiting convex ring of connecting rod contacts with wood drill chuck rear end face, increase stability during bore operation.
Advantageous Effects of the present utility model is: be convenient for carrying, promote operating efficiency.
In order to better understand technology contents of the present utility model, coordinate the coupling assembling of percussion drill referred to as this assembly this wood drill bit below.
Bolt is fixedly connected with on front side of second body of rod of the connecting rod of this assembly; After adopting such structure, when connecting rod coordinates with wood drill chuck, bolt replaces second body of rod to be resisted against the rear end face of installing hole, shortens the length of second body of rod, reduces the weight of connecting rod.
Accompanying drawing explanation
Fig. 1 is the example structure schematic diagram of this assembly wood drill chuck.
Fig. 2 is the embodiment front view of this assembly connecting rod.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the structural representation of this Assemblies Example.
Detailed description of the invention
As shown in Figure 4
This assembly comprises connecting rod 2 and wood drill chuck 1.
As shown in Figure 1
There is installing hole 11 at wood drill chuck 1 rear portion, and there is retaining thread hole 12 wood drill chuck 1 front portion.
As shown in Fig. 2 to 3
Connecting rod 2 comprises rear portion first body of rod 21, the position limiting convex ring 25 at middle part and second body of rod 23 of front portion, first body of rod 21 there is the keyway 22 coordinated with percussion drill chuck 3, the cross sectional shape of first body of rod is square, second body of rod 23 has external screw thread, on front side of second body of rod 23, axis direction is welded with bolt 24.
As shown in Figure 4
When processing wooden workpiece, first body of rod 21 of connecting rod 2 is fixedly mounted in the percussion drill chuck 3 of percussion drill, second body of rod 23 of connecting rod 2 and installing hole 11 threaded engagement of wood drill chuck 1, and position limiting convex ring 25 front end face of connecting rod 2 contacts with wood drill chuck 1 rear end face, the front end face of bolt 24 is resisted against on the rear end face of wood drill chuck 1 installing hole 11, wood drill bit 4 is fixedly mounted in the retaining thread hole 12 of wood drill chuck 1 front portion, make this device and wood drill bit 4 coaxial rotating, and carry out bore operation.
Above-described is only a kind of embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model principle; can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
