In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Not constituting conflict can be combined with each other.
Referring to Fig. 1, Fig. 1 is the structural schematic diagram that the utility model embodiment medium-length hole processes reamer.The utility model
A kind of deep hole machining reamer 100 that embodiment provides, including knife handle 10, connecting rod 20 and cutter head 30, one end of knife handle 10 and company
One end of extension bar 20 is fixedly connected, and the other end of connecting rod 20 is fixedly connected with one end of cutter head 30.
Specifically, knife handle 10 is cylindrical body, the deep hole machining reamer 100 has rotation axis A, rotation axis A and knife
The axis of handle 10 is overlapped.When being processed using deep hole machining reamer 100, the deep hole machining reamer 100 around rotation axis A into
Row rotation.
The connecting rod 20 is cylindrical body, and the axis of the connecting rod 20 is overlapped with the rotation axis A, the connecting rod
20 diameter is less than the diameter of the knife handle 10.One end of the connecting rod 20 is fixedly connected with one end of the knife handle 10, separately
One end is fixedly connected with the cutter head 30.
As shown in Fig. 2, above-mentioned cutter head 30 has a central spindle 31, it is provided with land 32 and chip space 33 in the central spindle 31,
Land 42 and chip space 43 are in the shape of a spiral.Land 42 and chip space 43 are set around the lateral surface of central spindle 31, and land 32
It is arranged alternately with chip space 33.Described 31 one end of central spindle is fixedly connected with the other end of the connecting rod 20.The cutter head 30 is big
Cause cylindrical, the diameter of the cutter head 30 is greater than the diameter of the connecting rod 20.The diameter of the knife handle 10 is greater than the knife
First 30 diameter
In the utility model embodiment, the number of the land 32 and chip space 33 is four, and the land
32 and chip space 33 be centrosymmetric relative to the rotation axis A.
It is understood that the number of the land 32 and chip space 33 is two, three in some other embodiment
It is a or four or more, and the land 32 and chip space 33 are centrosymmetric relative to the rotation axis A.
In the course of work of deep hole machining reamer 100, rotation need to be continued with cutting workpiece.In this process, deep hole adds
Work reamer 100 inevitably vibrates, and the vibration of the deep hole machining reamer 100 is along deep hole machining reamer 100
Radial direction vibration based on, radial vibration can be referred to as.It, can be serious if the radial vibration of deep hole machining reamer 100 is excessive
Influence the machining accuracy of deep hole machining reamer 100 and the service life of processing quality and deep hole machining reamer 100.
Intrinsic frequency is also referred to as natural frequency (natural frequency).When object does free vibration, displacement with
Time, the frequency of vibration was unrelated with primary condition by the variation of sinusoidal or cosine rule, and only with the inherent characteristic of object in relation to (such as
Quality, shape, material etc.), referred to as intrinsic frequency, the correspondence period is known as the natural period.The research of intrinsic frequency is conducive to
Guarantee product stability.It can be seen that the intrinsic frequency for avoiding deep hole machining reamer 100 is the key that reduce its radial vibration.
In three factors (quality, shape and material) of above-mentioned 100 intrinsic frequency of influence deep hole machining reamer, shape is
It is easier the factor for changing and designing.In the utility model embodiment, the length of the connecting rod 20 is L, the cutter head
30 length is D.Since the global shape (including length) of the cutter head 30 is the size in the hole by needing to process on workpiece
It determines, therefore the global shape of the cutter head 30 is fixed numbers.Preferably, in the utility model embodiment, the knife
First 30 length D is 30 millimeters.And the connecting rod 20 is connected between the cutter head 30 and knife handle 10, effect is for cutter head
30 provide withdrawing space.To guarantee that the deep hole machining reamer 100 has enough withdrawing spaces, the length of the connecting rod 20
L need to be more than or equal to 0.25D.
During the work time, vibration frequency is 500Hz to 1000Hz to the deep hole machining reamer 100.As shown in figure 3,
When the length L of the connecting rod 20 is in 0.25D between 0.4D, the intrinsic frequency of the deep hole machining reamer 100 is in
450Hz is between 650Hz.The intrinsic frequency of the deep hole machining reamer 100 is close to or at its operating vibration frequency range
It is interior.When the vibration frequency of the deep hole machining reamer 100 is equal or close to the intrinsic frequency of the deep hole machining reamer 100,
It can resonate, to greatly improve the amplitude of radial vibration, influence the processing quality of the deep hole machining reamer 100, even
The deep hole machining reamer 100 is broken.To avoid resonating, the length L of the connecting rod 20 need to be greater than or equal to
0.4D。
As shown in figure 4, the growth of the length L with the connecting rod 20, cutter head 30 in the deep hole machining reamer 100
Amplitude is gradually increased.When the length L of the connecting rod 20 is greater than 0.5D, the vibration of cutter head 30 in the deep hole machining reamer 100
Width is greater than 0.2 millimeter, then influences the processing quality of the deep hole machining reamer 100, be not able to satisfy the deep hole machining reamer 100
The requirement of machining accuracy.In the present embodiment, the length L of the connecting rod 20 is equal to 0.4D to 0.5D.Preferably, the connection
The length L of bar 20 is equal to 0.5D.
The beneficial effects of the utility model are: compared with prior art, the utility model provides a kind of deep hole machining hinge
Knife 100, comprising: one end of knife handle 10, connecting rod 20 and cutter head 30, one end of the connecting rod 20 and the knife handle 10 is fixed to be connected
It connects；One end of the cutter head 30 is fixedly connected with the other end of the connecting rod 20, and the length of the connecting rod 20 is equal to described
0.4 times to 0.5 times of 30 length of cutter head, the cutter head 30 have a central spindle, are provided with land 32 and chip removal in the central spindle 31
In the shape of a spiral, land 32 and chip space 33 are set around the lateral surface of central spindle 31, and sword for slot 33, land 32 and chip space 33
Band 32 and chip space 33 are arranged alternately, and described 31 one end of central spindle is fixedly connected with the other end of the connecting rod 20.More than being based on
The connecting rod 20 of structure, the deep hole machining reamer 100 has more reasonable length, can provide enough withdrawings for cutter head 30
Space, and can resonate to avoid deep hole machining reamer 100, thus reduce the amplitude of the deep hole machining reamer 100, to avoid
There are the lines that obviously quivers on workpiece.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；
