Description
Technical Field
The utility model relates to a cutter processing technology field especially relates to a grooving cutter.
Background
When a groove with an interference position is machined, the cutting depth is required to be larger and the entering space is smaller, the length of a blade is required to be as short as possible, but the cutting depth is required to be ensured, and the double-head blade in the common clamping mode occupies the space of the blade due to the integration of rear side positioning and the cutter bar, so that the length of the blade is limited and the required cutting depth cannot be achieved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a cutter arbor and blade components of a whole that can function independently are connected to under the prerequisite of guaranteeing the firm location, increased the grooving cutter of the actual processing length of blade.
In order to achieve the above purpose, the utility model provides a grooving cutter, which comprises a cutter bar and a blade; the head end of the cutter bar is a clamping part; the blade is clamped in the clamping part; a pressing plate is arranged at the top of the clamping part in advance; the pressing plate is fixed with the cutter bar through a fastener.
Preferably, the clamping is two clamping plates; a gap is preset between the two clamping plates; threaded holes in opposite positions are formed in the two clamping plates; the blade is clamped between the two clamping plates and screwed in the threaded hole through a screw, so that the two clamping plates clamp the blade.
Preferably, the clamping surfaces of the two clamping plates are inclined surfaces, and when the blade is clamped by the two clamping plates, the blade is pressed towards the bottom surface of the clamping part.
Preferably, a plurality of through holes are preset in the surface of the pressing plate, a plurality of threaded holes are preset in the surface of the cutter bar, and screws penetrate through the through holes and are screwed in the threaded holes to fixedly connect the pressing plate and the cutter bar.
Preferably, the head end of the blade is a cutter head, the tail end of the blade is a fixing part, the fixing part is clamped on the clamping part of the cutter bar, and the upper surface of the fixing part is in top contact with the pressing plate; the connecting surface of the fixing part and the clamping part is an inclined surface, and when the two clamping plates clamp the blade, the blade is pressed towards the bottom surface of the clamping part.
Compared with the prior art, the utility model has the advantages that: the utility model discloses a split type design of cutter arbor and blade adopts and is positioned cutter arbor clamping part connection structure with blade tail end fixed part centre gripping to adopt the clamp plate to prevent the design of blade dislocation, guaranteed the joint strength between blade and the cutter arbor, compare in the cutter of the integrative design of traditional blade cutter arbor simultaneously, the utility model discloses a cutter connection structure can dismantle, and connection structure is nimble, according to different processing technology, can select the blade of different length, can satisfy the grooving requirement of multiple degree of depth.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.
As shown in fig. 1 and 2, the present invention provides a grooving tool, which comprises a tool bar 1 and a blade 2; the head end of the cutter bar 1 is a clamping part 11; the blade 2 is clamped in the clamping part 11; a pressing plate 3 is arranged at the top of the clamping part 11 in advance; the pressing plate 3 is fixed with the cutter bar 1 through a fastener.
In this embodiment, the clamping is two clamping plates; a gap is preset between the two clamping plates; threaded holes in opposite positions are formed in the two clamping plates; the blade 2 is clamped between the two clamping plates and screwed in the threaded hole through a screw, so that the two clamping plates clamp the blade 2.
In this embodiment, two the holding surface of grip block is the inclined plane, works as two the grip block presss from both sides tightly behind the blade 2, the realization will blade 2 to the pressfitting of clamping part 11 bottom surface, the design on inclined plane has guaranteed the clamping effect of cutter arbor 1 to blade 2, avoids blade 2 to take place the phenomenon of skidding in clamping part 11.
In this embodiment, a plurality of through holes are preset on the surface of the pressing plate 3, a plurality of threaded holes are preset on the surface of the cutter bar 1, and screws pass through the through holes and are screwed into the threaded holes, so as to fixedly connect the pressing plate 3 and the cutter bar 1, and the pressing plate 3 plays a role of top support for the blade 2, so that the blade 2 cannot slide out of the clamping portion 11 under the condition of stress when grooving.
In this embodiment, the head end of the blade 2 is a cutter head, the tail end of the blade 2 is a fixing portion 21, the fixing portion 21 is clamped in the clamping portion 11 of the cutter bar 1, and the upper surface of the fixing portion 21 is in contact with the pressing plate 3; the connecting surface of the fixing portion 21 and the clamping portion 11 is an inclined surface, and when the two clamping plates clamp the blade 2, the blade 2 is pressed against the bottom surface of the clamping portion 11.
In this embodiment, the utility model discloses a split type design of cutter arbor 1 and blade 2 adopts and is located 11 connection structure of cutter arbor 1 clamping part with the 21 centre clampings of 2 tail end fixed parts of blade to adopt clamp plate 3 to prevent the design of blade 2 dislocation, guaranteed the joint strength between blade 2 and the cutter arbor 1, compare the cutter in the 1 integrative design of traditional 2 cutter arbor of blade simultaneously, the utility model discloses a cutter connection structure can dismantle, and connection structure is nimble, according to different processing technology, can select the blade 2 of different length, can satisfy the grooving requirement of multiple degree of depth.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
