Abstract
The utility model discloses a cutter bar used for cutting a clamp spring groove in a deep hole and belongs to the field of machining tools. The cutter bar comprises a connecting handle and a cutter back, wherein the connecting bar and the cutter back are fixed through nuts. The cutter bar is characterized in that the top end of the cutter back is provided with a pushing rod which extends into the cutter back, and a clamping threaded rod, a compression spring, a blade sliding block, and a blade are successively arranged inside the cutter back. Besides, one end of the clamping threaded rod is connected with the connecting handle, and the other end of the clamping threaded rod is connected with the compression spring. The compression spring is installed on a spring seat, and the spring seat is fixed on a pushing arm through nuts. A blade is further installed inside the cutter back. The blade is arranged on the blade sliding block and is fixed on the cutter back through nuts. The cutter bar used for cutting the clamp spring groove in the deep hole is simple in structure, convenient to operate, time-saving and labor-saving in the machining process, and capable of largely improving working efficiency. Furthermore, in the whole machining process, a workpiece can be fixed tightly, a machine tool spindle drives the cutter back to rotate so as to drive the blade to rotate, and machining is safe and reliable.
Description
Technical field
The utility model relates to a kind of machining tool, relates in particular to a kind of deep hole and cuts the jump-ring slot knife bar, mainly is applicable to the processing to the deep hole jump-ring slot.
Background technology
Behind Drilling operation, often can run into the processing of jump-ring slot in the requirement hole, general processing technology is after first workpiece to be processed being clamped with chuck, use shaped profile turning cutter to carry out turning, but common technique to cause work efficiency low owing to operating procedure, has wasted the time; And for large workpiece, because the weight of workpiece own is large, carrying, clamping are all very difficult, add and require great effort very much man-hour; And owing to measure difficulty, thus the size of wayward processing, and then affect the quality of workpiece.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of deep hole simple in structure, easy to operate, that machining accuracy is high to cut the jump-ring slot knife bar.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of deep hole is cut the jump-ring slot knife bar, comprise and connect handle and knife bar, describedly connect handle and knife bar is fixed by nut, it is characterized in that: described knife bar top is provided with the pushing ram that extends to knife bar inside, be disposed with clamping screw, Compress Spring, knife block and blade in the described knife bar, clamping screw one end with connect handle and be connected, the other end connects Compress Spring, Compress Spring mounts elastically, spring base is fixed on the pushing ram by nut, also be provided with blade in the described knife bar, blade is arranged on the knife block, and knife block is fixed on the knife bar by nut.
The beneficial effects of the utility model are: the utility model is connected with machine tool chief axis and realizes rotatablely moving by connecing handle, thereby the blade in the drive knife bar rotatablely moves, blade inwardly promotes to determine outside the stretching out highly of blade by pushing ram, and blade outside stretch out the degree of depth that highly determines the workpiece to be machined slotted eye; The effect of Compress Spring is when guaranteeing to machine, and pushing ram is resetted, thereby so that in the blade retraction knife block.The utility model is simple in structure, easy to operate, and is time saving and energy saving in the process, greatly improved operating efficiency, and in whole process, workpiece can maintain static, and drives blade rotation thereby only drive the knife bar rotation by machine tool chief axis, and process safety is reliable.
Description of drawings
Fig. 1 is that a kind of deep hole of the utility model is cut jump-ring slot lever structure schematic diagram.
Wherein: 1-connects handle; The 2-knife bar; The 3-nut; The 4-pushing ram; The 5-clamping screw; The 6-Compress Spring; The 7-knife block; The 8-blade; The 9-spring base.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of deep hole is cut the jump-ring slot knife bar, comprise and connect handle 1 and knife bar 2, it is fixing by nut 3 to connect handle 1 and knife bar 2, knife bar 2 tops are provided with the pushing ram 4 that extends to knife bar inside, be disposed with clamping screw 5 in the knife bar 2, Compress Spring 6, knife block 7 and blade 8, clamping screw 5 one ends with connect handle 1 and be connected, the other end connects Compress Spring 6, Compress Spring 6 is installed on the spring base 9, and spring base 9 is fixed on the pushing ram 4 by nut 3, also is provided with blade 8 in the knife bar 2, blade 8 is arranged on the knife block 7, and knife block 7 is fixed on the knife bar 2 by nut 3.
The utility model is to realize like this, at first the processing end face with workpiece to be processed leans against on the blade 8, be connected with machine tool chief axis and realize rotatablely moving by connecing handle 1, thereby the blade 8 that drives in the knife bar 2 rotatablely moves together along with connecing handle 1, by inside promotion pushing ram 4, make the outstanding beginning of blade 8 bore holes, blade 8 inwardly promotes to determine blade 8 outside stretching out highly by pushing ram 4, and blade 8 outside stretch out the degree of depth that highly determines the workpiece to be machined slotted eye; After the process finishing, remove the thrust power of pushing ram 4, Compress Spring 6 resets pushing ram 4, thereby so that in the blade 8 retraction knife blocks 7, knife bar 2 leaves processing work, finishes processing.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
