Abstract
The utility model discloses a Morse handle of a countersink rod, which comprises a body. A conical handle is arranged at one end of the body, and a countersink rod installing groove is formed at the other end thereof; and an inserted pin hole is formed on one side of the countersink rod installing groove. By adopting the technical scheme provided by the utility model, the Morse handle and the countersink rod are processed respectively; through the matching and connection between the countersink rod installing groove on the Morse handle and the handle part of the countersink rod as well as the connection between the inserted pin arranged on the handle part of the countersink rod and the inserted pin hole on the Morse handle for the countersink rod, the operation of countersinking the hole end surfaces with various specifications on the same workpiece can be realized only by changing the countersink rods with the corresponding specifications, thereby improving work efficiency and reducing labor intensity.
Description
Technical field
The utility model relates to a kind of Counterboring bar morse shank.
Background technology
The ream truncation of bolt hole end face is at present cut, and usually with the morse shank disjunctor ream bar of being with tang, and can only the upper surface of datum hole be processed, and the lower surface must adopt the clamping mode of changing shank to operate.And need to change together with morse shank according to each datum hole specification, can be described as the different size datum hole, must distinguish different knife bars, wherein the knife bar that forward and reverse ream is cut is distinguished again.Datum hole if any plurality of specifications on the same workpiece needs positive ream or anti-ream, and frock is changed frequent, reduces operating efficiency; And a datum hole adopts a knife bar, the making material of waste frock.
The utility model content
Technical problem to be solved in the utility model provides a kind of Counterboring bar morse shank.Ream to the plurality of specifications hole end surface on the same workpiece is cut, and only needs the ream bar of the corresponding specification of transposing, just can realize operation, thereby improve operating efficiency, has alleviated labour intensity.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: Counterboring bar morse shank, comprise body, and described body one end is provided with taper shank, and the other end is provided with ream bar mounting groove, and described ream bar mounting groove one side has pin hole.
The bottom of described ream bar mounting groove is provided with spring assembly.
Described spring assembly comprises spring, core bar, and described spring housing is located on the described core bar, and described core bar one end is provided with an elongated hole, and described core bar is connected with body by the round pin that passes elongated hole.
Described pin hole is H shape hole, and described H shape hole comprises first cave, the 3rd cave and second cave, the 4th cave that is interconnected.
Described taper shank is provided with and is seated the hole, so that the counter-force when avoiding ream to cut in when falling the ream pulls morse shank.
The utility model is owing to adopted technique scheme, Counterboring bar morse shank and ream bar are processed respectively, be complementary with the shank of ream bar by the ream bar mounting groove on the Counterboring bar morse shank and be connected, the latch that is provided with by ream bar shank is connected with pin hole on the Counterboring bar morse shank again, ream to the plurality of specifications hole end surface on the same workpiece is cut, and only needs the ream bar of the corresponding specification of transposing, just can realize operation, thereby improved operating efficiency, alleviated labour intensity.
Description of drawings
Fig. 1 is the structural representation of the utility model Counterboring bar morse shank.
Fig. 2 is that the N of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.
Figure 1 shows that the utility model Counterboring bar morse shank, comprise body 1, described body 1 one ends are provided with taper shank 11, are used for being connected with machine shaft, and the other end of body 1 is provided with ream bar mounting groove 12, and described ream bar mounting groove one side has pin hole 3.The bottom of described ream bar mounting groove 12 is provided with spring assembly.Described spring assembly comprises spring 21, core bar 22, and described spring 21 is sheathed on the described core bar 22, and described core bar 22 1 ends are provided with an elongated hole 23, and described core bar 22 is connected with body 1 by the round pin 24 that passes elongated hole 23.Described pin hole 3 is H shape hole, and as shown in Figure 2, described H shape hole comprises first cave 31, the 3rd cave 33 and second cave 32, the 4th cave 34 that is interconnected.Described taper shank 11 is provided with and is seated hole 111.
In manipulating, only need the H shape hole that the latch on the ream bar shank is aimed on the morse shank is inserted in the ream bar mounting groove 12, ream is carried out when cutting in the bolt hole upper surface, the latch on the ream bar shank is screwed in first cave 31 or second cave 32 in H shape hole; Ream is carried out when cutting in the bolt hole lower surface, in the 3rd cave 33 of the latch on the ream bar shank or the 4th cave 34.According to about the countersink cutting edge and the direction of rotation of drill press spindle, in first cave 31, second cave 32 and the 3rd cave 33, the 4th cave 34, elect respectively, the ream of same specification and suitable ream, needn't dismantle the ream bar, only need the cutting direction of change cutting edge roundness, in first cave 31, second cave 32 and the 3rd cave 33, the 4th cave 34, elect respectively again, can operate, improved operating efficiency.
The set spring assembly in described ream bar mounting groove bottom plays the ream bar and shirks conveniently, the main effect that is used in the cutter that rises when bolt hole lower surface ream cut.In when falling the ream, also need with tight being seated in the hole 111 on morse shank of cone pin edge, the counter-force when avoiding ream to cut pulls morse shank.
Adopt the utility model Counterboring bar morse shank, only need the size of the shank of ream bar and the latch that shank is provided with to keep suitable respectively with the size of the ream bar mounting groove of the utility model Counterboring bar morse shank and pin hole, the datum hole size difference at processed position no matter, or, all can reach processing purpose to the positive and negative ream of datum hole both ends of the surface.
