Abstract
The utility model discloses a clamping tool of a needle rod frame, comprising a base. The clamping tool is characterized in that the base is provided with a supporting plate which is vertically arranged; a concave cavity is formed at the top part of the supporting plate, and is provided with a first side wall and a second side wall which are oppositely arranged; the first side wall and the second side wall are provided with through holes which are mutually aligned, and the the needle rod frame can penetrate through the through holes; and one side of the supporting plate is also provided with a knife rest. Compared with the prior art, the clamping tool disclosed by the utility model has the advantages that an existing installation clamp is improved, and an original V-shaped clamping groove is changed into the through holes through which a workpiece can penetrate, so that the positioning of the workpiece on the clamp is more accurate and reliable, the movement and the rotation of the workpiece are effectively prevented, the positioning accuracy is improved, and the processing quality of the workpiece is ensured.
Description
Technical field
The utility model relates to a kind of instrument that clamps of needle bar frame.
Background technology
Needle bar frame is one of sewing machine parts commonly used, and this class needle bar frame part mostly is slender structure, is adding man-hour, need carry out punch operation to an end of needle bar frame usually.
Traditional be used for needle bar frame to clamp tool construction comparatively simple, offer V-shaped groove on the frame of these class anchor clamps, needle bar frame directly is placed on the V-shaped groove, but there is a shortcoming in this instrument that clamps, and it is spacing to be exactly that V-shaped groove does not have vertically, when punching is done manual work, needle bar frame rolls easily, and can be along axially the moving around of V-shaped groove, thus cause needle bar frame accurately to locate, and machining accuracy is low.
The utility model content
Technical problem to be solved in the utility model be provide a kind of installation to put in place accurately more at above-mentioned prior art present situation needle bar frame clamps instrument.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of needle bar frame clamps instrument, comprise pedestal, it is characterized in that: described pedestal has the support plate of vertical setting, the top of described support plate is formed with cavity, this cavity has the first side wall and second sidewall of establishing relatively respectively, offer the through hole of the mutual alignment that can pass for needle bar frame on described the first side wall and second sidewall, a side of described support plate also is provided with knife rest.
Move axially along the through hole on the cavity side walls for fear of needle bar frame, as preferably, described cavity is provided with pressing plate, wherein, offers axis hole on the described pressing plate, is equipped with the bolt that can offset with the needle bar frame workpiece in the described axis hole.
In order to prevent that further needle bar frame from rotating, guarantee the reliability of positioning of needle bar frame, as preferably, the threaded shank of described bolt also is arranged with spring, one end of described spring and the lateral wall of needle bar frame workpiece offset, and the other end of this spring and the inwall of pressing plate offset.
As preferably, offer the drill bushing that can supply cutter head to pass on the described knife rest.
Compared with prior art, advantage of the present utility model is: existing sectional fixture is improved, original V-arrangement draw-in groove made into the through hole that can pass for workpiece, make the location of workpiece on anchor clamps more can be accurately, by property, effectively prevent workpiece movement and rotation, improve positioning accuracy, guarantee the crudy of workpiece.
Description of drawings
Fig. 1 clamps tool construction schematic diagram (comprising workpiece to be machined) for the utility model embodiment's.
Fig. 2 is the three-dimensional exploded view (comprising workpiece to be machined) of the instrument that clamps of the utility model embodiment.
The specific embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment.
As Fig. 1～shown in Figure 2, present embodiment is a kind of instrument that clamps of needle bar frame, this instrument of clamping includes pedestal 1, form the support plate 11 of vertical setting on the pedestal 1, the top of this support plate 11 is formed with the cavity 12 of rectangle, cavity 12 has the first side wall 121 and second sidewall of establishing relatively respectively 122, wherein, offer the through hole 123 of mutual alignment on the first side wall 121 and second sidewall 122 respectively, one side of support plate 11 also is provided with knife rest 2, offers the drill bushing 3 that can supply cutter head to pass on the knife rest 2.
In order further to improve the reliability of positioning of workpiece, prevent that workpiece from rotating, also be provided with pressing plate 4 on the cavity 12, offer axis hole 41 on this pressing plate 4, be equipped with the bolt 5 that can offset with the outer wall of needle bar frame workpiece 7 in the axis hole 41; Contact with needle bar frame workpiece 7 rigidity for fear of bolt 5, prevent that needle bar frame workpiece 7 outer walls from damaging, the threaded shank of bolt 5 also is arranged with spring 6, one end of spring 6 and the lateral wall of needle bar frame workpiece 7 offset, and the inwall of the other end of this spring 6 and pressing plate 4 offsets, so, under the resilient force of spring 6, bolt 5 in screwing process, can be not directly and needle bar frame workpiece 7 produce the rigid shock power, but realize Elastic Contact by spring 6.
During installation, earlier the bolt 5 on the pressing plate 4 is unscrewed, needle bar frame workpiece 7 is arranged in the through hole 123 of the mutual alignment on the support plate 11, realize the axial location of needle bar frame workpiece 7; Then, bolt 5 is screwed and contact in needle bar frame workpiece 7, realize needle bar frame workpiece 7 rotary spacing along the circumferential direction; The cutter head of process tool passes by the drill bushing 3 on the knife rest 2, realizes the end boring processing to needle bar frame workpiece 7 thus.
Claims (4)
