Abstract
The utility model discloses a clamp for parts of a sewing machine. The clamp comprises a clamp body and is characterized in that the center of the clamp body is provided with a center shaft capable of being connected with a lathe rotating shaft, the clamp body is provided with clamping holes capable of accommodating the parts to be processed along the circumferential direction, and the clamping holes are through holes matched with the parts to be processed in shape and size, and the thicknesses of the through holes are matched with those of the parts to be processed.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of anchor clamps that are used for sewing machine component processing.
Background technology
The parts of sewing machine are of a great variety, and are mostly irregular structure, all need design specific anchor clamps in the time of processing and install and locate.
As shown in Figure 4, be a kind of sewing machine component structural representation of the prior art, this part 4 includes integrated bumping square 41 and semi-circular profile 42; Usually need to process two parallel surfaces of this part 4, utilize the mode of traditional this part of clamps, not only need clamp bumping square 41 and semi-circular profile 42; Also need again one of them plane to be close to the blank plane, and processing mode adopt milling machine processing more, owing to receive the restriction of anchor clamps; After this part clamps; Can only process a plane at every turn, therefore need the two-sided processing of twice complete whole part of clamping ability, working (machining) efficiency is low; And, fix part through being close to the blank plane, can be because the machining accuracy on one of them plane of part be not high, remote-effects can't guarantee the depth of parallelism of two machined surfaces to the machining accuracy on another plane.
The utility model content
The utility model technical problem to be solved be provide to above-mentioned prior art present situation a kind of working (machining) efficiency high, clamp convenient and the high sewing machine component anchor clamps of machining accuracy.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of sewing machine component anchor clamps; Include chuck body; It is characterized in that: described chuck body center is provided with the central shaft that can be connected with the lathe rotating shaft; Described chuck body is along the hole that clamps that circumferentially also offers the ccontaining part to be processed of a plurality of abilities; Each is said to clamp the suitable through hole of shape of cross section that the hole is shape size and said part to be processed, and this clamps the thickness of the thickness in hole less than said part to be processed.
In order to improve the installation reliability of part to be processed; Prevent that part from dropping out from clamping in the hole of anchor clamps; As preferably; Described chuck body also offers and can clamp the side direction through hole that the hole is connected with said along circumferential side wall, is equipped with the screw rod that can be tight against mutually with described part to be processed in the said side direction through hole.So, through the lateral support of screw rod, can guarantee the reliable location of part to be processed in clamping the hole, prevent that part from dropping.
For improving working (machining) efficiency, preferred as further, the described Kong Yousi that clamps is individual, respectively axially evenly distributing along said chuck body.The quantity that clamps the hole can be processed needs setting according to reality, is the best with 4 on a circle, and lathe is adding man-hour, and revolution is crossed 90 degree can process a part, convenient control.
Compared with prior art; The advantage of the utility model is: on chuck body, offer a plurality of holes that clamp, and make that the shape that clamps hole outline big or small and processed part is suitable, can make things convenient for the location that clamps of part thus; Clamp the hole and can locate as long as part put into; Need not to re-use the blank plane and fix part, reduced the time of clamping, improved operating efficiency; And, also be provided with central shaft on the chuck body, can whole anchor clamps be connected in the lathe rotating shaft, make that anchor clamps once clamp after, can process the piece surface that clamps the both sides, hole that is positioned at these anchor clamps simultaneously, further improved operating efficiency; In addition, chuck body also offers the side through hole and is arranged in the bolt in this side through hole, can be from the side part to be processed be closely attached on through bolt to clamp in the hole, guarantees the reliability that part clamps.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Present embodiment is a kind of anchor clamps that are used for sewing machine component processing, and processed sewing machine component structure is as shown in Figure 4, and the working position of this part 4 is the both sides parallel surface.
The anchor clamps of present embodiment such as Fig. 1～shown in Figure 3; These anchor clamps include the rounded chuck body in cross section 1 (also can be the cross section of square or other shapes); The center of chuck body 1 offers axis hole 13, is connected with central shaft 2 in this axis hole, and central shaft 2 can be connected with the rotating shaft 51 of lathe 5;
The surface of chuck body 1 along circumferentially offer four that evenly arrange and can ccontaining part to be processed 4 clamp hole 11 (quantity that clamps the hole can be processed needs according to reality and increase and decrease to some extent); Wherein, Clamping hole 11 is a through hole; This shape shape of cross section size big or small and part to be processed 4 that clamps hole 11 is suitable, owing to need process two parallel surfaces of part to be processed 4, therefore; The thickness that clamps hole 11 makes two parallel surfaces of part to be processed 4 be exposed to outside the chuck body 1 then less than the thickness of part to be processed 4.
In order to improve the reliability that clamps of part to be processed; Prevent that part to be processed from dropping out from clamping the hole 11 of chuck body 1; Chuck body 1 can be respectively and the side direction through hole 12 that clamps hole 11 corresponding connections accordingly along also offering on the circumferential side wall; Be equipped with a screw rod 3 in each side direction through hole 12, the screw rod 3 of screwing can make the top of screw rod 3 be tight against mutually with part to be processed 4, thereby lets part to be processed 4 be close to the inwall that clamps hole 11.
During use, as shown in Figure 3, the central shaft 2 of chuck body 1 is installed in the rotating shaft 51 of lathe 5; Front and back position in chuck body 1 all can be provided with cutter 6, once clamps four parts to be processed 4 can be installed on chuck body 1, can process simultaneously the front/rear end of each part 4 through two cutters 6; Not only improve operating efficiency, and guaranteed the depth of parallelism of two end faces, improved machining accuracy; Be compared to existing conventional brace; The anchor clamps of present embodiment have not only reduced the time of clamping, and have shortened machining period, thereby have improved working (machining) efficiency greatly.
