Abstract
The utility model relates to a self-centering double-station circular rack gear milling clamp, which comprises a tong body, a movable tong port, a movable tong port body, an oil tank and a fixed tong port. The self-centering double-station circular rack gear milling clamp is characterized in that the movable tong port body is connected with the tong body in rotating mode through a first shaft, and a second shaft is arranged on the movable tong port body. A wedge for supporting the second shaft is connected with an oil tank push rod. A tong port supporting frame is arranged at the position of the movable tong port body away from the oil tank and connected with the movable tong port body rotating mode through a third shaft. Arc faces contacted with each other are arranged on the tong port supporting frame and the movable tong port, and a locating structure and a connection structure are arranged between the tong port supporting frame and the movable tong port. By means of the clamp, a workpiece is clamped by pushing the movable tong port body to rotate through the oil cylinder. Due to the fact that the tong port supporting frame can rotate around the first shaft, the movable tong port can rotate along the arc faces, therefore for irregular workpiece clamping faces, the movable tong port can always be adjusted to a state of being contacted with the workpiece clamping face. Accordingly, a workpiece is clamped between two tong ports firmly and stably and prevented from loosening, service life of a tool is prolonged, gear milling quality is improved, and workpiece machining efficiency is improved.

The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1-4, self-centering double circular rack gear milling clamper comprises vice body 1, moving jaw 2, moving jaw body 3 and is packed in oil cylinder 4 and the regular jaw 5 on the vice body.Concrete, installing connecting plate 6 in the end of vice body, oil cylinder is installed on the connecting plate.Said moving jaw body is rotationally connected with vice body through horizontally disposed first 7, near the position of oil cylinder second 8 of horizontal direction is installed on the said moving jaw body.Said cylinder putter end is connected with and supports second voussoir 9, and said voussoir horizontal slip is installed on the vice body.Concrete, voussoir is located between second and the vice body, and its wedge end face supports second.Second can be rotatably installed on the moving jaw body through bearing, and when adopting this syndeton, the wedge end face of voussoir can directly contact with second; Second also can be packed on the moving jaw body, when adopting this syndeton, and suit axle sleeve on second, the wedge end face of voussoir contacts with axle sleeve.Can be connected through line slideway auxiliary between above-mentioned voussoir and the vice body; It is compacter for voussoir is connected with vice body; Voussoir can be made up of upper and lower two parts; Wherein the latter half 9-2 is wider than the first half 9-1, on vice body, is shaped on the groove that cooperates with the latter half, is fixed with the pressing plate 10 that moves on the restriction voussoir in the both sides, upper end of groove.Be provided with jaw carriage 11 at the moving jaw body away from the position of oil cylinder, said jaw carriage is rotationally connected with the moving jaw body through vertically disposed the 3rd 12.Concrete, can on the end face of moving jaw body, groove 3-1 be set near regular jaw, the bossing 11-1 that is inlaid in the groove is set on the jaw carriage, said the 3rd is installed in the groove.Adopt said structure; For guaranteeing that the jaw carriage freely rotates along the 3rd; In theory; The end face that matches between jaw carriage and the moving jaw body be with the 3rd be the arc surface at center, but consider that the end face that matches between above-mentioned jaw carriage and the moving jaw body adopts and the reverse arc surface structure of theoretical arc surface from the processing technology and the syndeton between the part of part.Adopt under the situation of reverse arc surface structure, in the certain angle scope, rotate along the 3rd for guaranteeing the jaw carriage, the end face that matches between above-mentioned jaw carriage and the moving jaw body does not contact, and is provided with the certain clearance amount between the both ends of the surface.In addition, also need reserve certain clearance between the axis hole between the bottom surface of the outside of above-mentioned bossing and groove, on the bossing and the 3rd.Above-mentioned jaw carriage and moving jaw are provided with the arc surface 13 that forms contact matching; The central shaft of said arc surface is a horizontal direction, is provided with the mobile vertically location structure of restraint jaw between said jaw carriage and the moving jaw and moving jaw is pressed on the syndeton on the jaw carriage.
Above-mentioned location structure restraint jaw on the one hand moves vertically, will guarantee that on the other hand moving jaw freely rotates vertically.This location structure can be made up of with the positioning key 14 that is inserted in the keyway the keyway that is located on the fit circular arc face, and said keyway and positioning key all are provided with along the arc surface direction.Above-mentioned syndeton will guarantee that the arc surface of moving jaw is pressed on the corresponding circle cambered surface of jaw carriage, will guarantee that on the other hand moving jaw freely rotates vertically in certain angular range on the one hand.This syndeton can be by the oval shape counter sink 15 that is located at positioning key both sides on the moving jaw, be installed in that stage clip 17 constitutes between the end face of the screw 16 that is connected with the jaw carriage in the counter sink and head end that is pressed on screw and counter sink.
The angle of chamfer of above-mentioned voussoir is less, behind the locking workpiece, forms self-locking state, guarantees that work in-process moving jaw body is not loosening.Voussoir is bigger to the distance of the moving jaw body centre of gyration than moving jaw and workpiece clamping area to the distance of the moving jaw body centre of gyration with second contact in addition, and the thrust of oil cylinder plays amplification through leverage, so the thrust of oil cylinder needn't be too big.This has created condition for choosing the minor diameter oil cylinder.
Be to improve working (machining) efficiency, above-mentioned vice body can be made symmetrical structure, and above-mentioned moving jaw, moving jaw body, oil cylinder, regular jaw and jaw carriage are two and symmetry and are installed on the vice body.Adopt above-mentioned symmetrical structure, can two workpiece 18 of a clamping, realize the time processing moulding, thereby improve working (machining) efficiency.
