Description
Technical Field
The utility model relates to the technical field of clamping auxiliary pieces used in a workpiece machining process, in particular to a traceless clamp.
Background
When a workpiece needs to be machined on a lathe, the following two ways are generally adopted:
firstly, directly clamping a workpiece, namely directly clamping the workpiece on a machine tool, and taking down the workpiece after machining is finished, wherein the clamping method usually has clamping marks on the outer surface of the workpiece, and particularly when the workpiece is an appearance piece, the clamping marks cause the disqualification of the workpiece;
secondly, clamping the raw material on a machine tool, wherein the length to be processed is smaller than the extending length of the raw material, and cutting off the workpiece from the raw material after the processing is finished, but the clamping processing mode has the problem of material falling, and the fraction defective of the cut surface accounts for about 1.5%;
the two modes have low production efficiency and low product percent of pass, can not meet the production requirements and need improvement.
Disclosure of Invention
The utility model aims to overcome the defects of low production efficiency and low yield in the prior art, and provides a traceless clamp.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
the utility model provides a no trace anchor clamps, includes the body, the body is equipped with first tip, first feed inlet, first recess and first breach, first feed inlet is from first tip and the orientation is kept away from the direction extension of first tip, the length direction setting of body is followed to first recess, first recess and first feed inlet intercommunication, the bore of first feed inlet is greater than the bore of first recess, first breach runs through the thickness of body, first breach and first feed inlet intercommunication, first breach and first recess intercommunication, first breach is from first tip.
Further, first feed inlet is the frustum form, the central axis collineation setting of body, first feed inlet, first recess.
Further, the body still includes first portion and the second portion of being connected with first portion, the radial specification of first portion is greater than the radial specification of second portion, first feed inlet, first recess and first breach are all located first portion.
Further, the body still includes the second recess, the second recess sets up along the axial of body, the second recess with first recess intercommunication.
Further, the second groove is formed in the second portion.
The utility model has the beneficial effects that: the traceless clamp is arranged to serve as an auxiliary production workpiece, so that the production efficiency and the production quality of the workpiece are improved, and the processing requirement of an appearance piece is met.

Detailed Description
For the understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.
Referring to fig. 1, the traceless clamp of the present invention includes a body, the body is provided with a first end portion 11, a first feed port 12, a first groove 13 and a first notch 14, the first feed port 12 extends from the first end portion 11 and faces a direction away from the first end portion 11, the first groove 13 is arranged along a length direction of the body, the first groove 13 is communicated with the first feed port 12, a caliber of the first feed port 12 is greater than a caliber of the first groove 13, the first notch 14 penetrates through a thickness of the body, the first notch 14 is communicated with the first feed port, and the first notch 14 starts from the first end portion 11.
Specifically, in this embodiment, the first groove 13 is a circular hole, the workpiece to be machined extends into the first groove 13, the first groove 13 is used for fixedly clamping the workpiece to be machined, the diameter of the cross section of the first groove 13 is the same as the diameter of the workpiece to be machined, the cross section of the first feed inlet 12 is in a circular angle shape, the caliber of the first feed inlet 12 is larger than the caliber of the first groove 13, the workpiece to be machined is conveniently placed into the first groove 13, the first notches 14 are in a long strip shape, the number of the first notches 14 is two, the two first notches 14 are symmetrically arranged with respect to the central axis of the body, the first notches 14 start from the first end portion 11 and penetrate through the wall thickness of the body, the first notches 14 are respectively communicated with the first feed inlet 12 and the first groove 13, so that the seamless fixture has elasticity in the radial direction, the workpiece to be machined extends into the first groove 13 conveniently, after the workpiece to be machined is completely clamped, and clamping the traceless clamp on the machine tool, then machining the workpiece, and after the workpiece is machined, simultaneously taking down the traceless clamp and the workpiece from the machine tool, so that the workpiece is in zero contact with the clamp of the machine tool, and the purpose that the workpiece has no clamping mark is realized.
The traceless clamp is arranged to serve as an auxiliary production workpiece, so that the production efficiency and the production quality of the workpiece are improved, and the processing requirement of an appearance piece is met.
The body still includes first portion 101 and the second portion 102 of being connected with first portion 101, the radial specification of first portion 101 is greater than the radial specification of second portion 102, first portion 101 is all located to first end 11, first feed inlet 12, first recess 13 and first breach 14, and first portion 101 and second portion 102 are the echelonment setting, make things convenient for the uniformity of lathe centre gripping body length, easy operation.
The body still includes second recess 15, second recess 15 sets up along the axial of body, second recess 15 with first recess 13 intercommunication, the setting of second recess 15 reduces body weight, and the bore of second recess 15 is greater than the bore of first recess 13, and first breach 14 and the setting of second recess 15 interval ensure the clamping-force of first portion 101.
The second groove 15 is provided in the second portion 102.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
