Abstract
The utility model discloses a fixture special for a lathe for turning the side face of an irregular workpiece. The fixture is structurally characterized in that a base is vertical to a disk chuck; a circular boss is reserved on the base; one end of a straight line, on which a diameter, which is parallel to the disk chuck, of the disk chuck is positioned, is provided with a thick bracket; the other end of the diameter is provided with thin brackets on both sides of the line; the outer side of the circular boss on the base is provided with a positioning block; the disk chuck, the base, the thick bracket, the thin brackets, the circular boss and the positioning block are molded integrally by casting; the middle position of a swinging arm is hinged to the end part of the thick bracket; bolts are hinged to the two ends of the swinging arm respectively; screw caps are connected to the bolts by using threads; the end parts of the two thin brackets are hinged to clamping arms; the other ends of the clamping arms are provided grooves of which the diameters are slightly larger than those of bolt rod parts, and the same ends are provided with convex teeth; a balance block is further arranged on the disk chuck.
Description
Technical field
The utility model relates to a kind of horizontal lathe special fixture, especially a kind of special fixture that adopts horizontal lathe processing X6325 milling machine bearing side plane.
Background technology
Add man-hour running into the plane machining and the arc surface that carry out with same locate mode, some enterprise processes respectively, makes like this production efficiency low, and the cost dropping into is also larger; When the processing of plane machining and arc surface is placed in same procedure, many enterprises are used milling machine to process; Also some enterprise selects lathe to process.Selecting milling machine to add man-hour, because required precision is not high, so make production efficiency low.Selecting lathe to add man-hour, in view of being irregular, generally select four-jaw chuck, due to the particularity of this blank, adopt after chuck clamping, when High Rotation Speed, may there is the phenomenon of clamping shakiness.
Summary of the invention
The technical problems to be solved in the utility model is to provide the special fixture of a kind of convenient mounting and clamping, safe and reliable car X6325 bearing side plane.
For solving the problems of the technologies described above, the lathe-use clamp structure for the irregular side surface of workpiece of turning of the present utility model is: comprise floral disc, base, thick support, ramuscule frame, round boss, swing arm, clamp arm, bolt, nut, locating piece; Described base is perpendicular to floral disc; On described base, leave round boss; There is thick support one end that is parallel to the diameter of floral disc for described round boss, and there is respectively ramuscule frame the online both sides of the diameter other end; On described base, in round boss outside, also has a positioning block; Described floral disc, base, thick support, ramuscule frame, round boss, locating piece are by casting global formation; Described swing arm is hinged with thick bracket end in middle part; Described swing arm two ends are link bolt respectively; On described bolt with the nut that has been threaded; Described two thin bracket end and clamp arm are hinged; The described clamp arm other end has groove, and groove diameter is slightly larger than bolt shank diameter.
On this basis, on described bolt, also cover has spring washer.
On this basis, described clamp arm is opened reeded one end and is outwards left double wedge.
On this basis, described floral disc is provided with balance weight in the edge on base opposite.
The beneficial effect of utility model: the utility model has the advantage of: 1, only workpiece need to be placed on base, clamp arm is stuck on bolt, screw nut, simple to operate, convenient mounting and clamping; 2, spring washer is installed, and clamp arm also leaves double wedge in recessing place, prevent that lathe from producing fixture clamping when work loosening, workpiece flies out, safe and reliable; 3, balance weight is installed, while having guaranteed lathe work, workpiece stability of rotation, reduces vibration.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Figure 1 shows that the side view of the utility model for the lathe-use clamp of the irregular side surface of workpiece of turning.
Figure 2 shows that the front view of the utility model for the lathe-use clamp of the irregular side surface of workpiece of turning.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is comprised of following part for the lathe-use clamp of the irregular side surface of workpiece of turning: floral disc 1, base 2, thick support 3, ramuscule frame 4, round boss 5, swing arm 6, clamp arm 7, bolt 8, nut 9, locating piece 10, spring washer 11, double wedge 12, balance weight 13.
Above-mentioned base 2 is perpendicular to floral disc 1, and by integrated poured moulding.At the upper surface of base 2, be also cast with a round boss 5, the diameter of round boss 5 is depending on workpiece bottom diameter of bore.One end that is parallel to the diameter place straight line of floral disc 1 for round boss 5 is cast with thick support 3, ramuscule frame 4 is poured into a mould respectively in the online both sides of the diameter other end, and the distance between the perpendicular perpendicular to floral disc 1 and two ramuscule frame 4 place planes at thick support 3 places is slightly larger than the outer diameter of a circle of side surface of workpiece.On base 2, in round boss 5 outsides, also have a positioning block 10, determine according to workpiece the position of locating piece 10.Thick support 3 upper ends and swing arm 6 middle parts are hinged, and the two ends of swing arm 6 are hinged with respectively bolt 8, and bolt 8 has also been threaded connection nut 9.The top of ramuscule frame 4 and clamp arm 7 are hinged; The length of clamp arm 7 is greater than side surface of workpiece outside diameter, and the other end has groove, and groove diameter is slightly larger than bolt 8 bar portion diameters.
For do not make fixture when work bolt 8 with nut 9 between produce loosening, can also be on bolt 8 sleeve spring packing ring 11, when clamping, spring washer 11, between clamp arm 7 and nut 9, prevents that nut 9 is owing to shaking the auto back pine of generation; Clamp arm 7 outwards leaves double wedge 12 opening jagged position in addition.
Use principle: this fixture on the ring flange of spindle stock, drives the rotation of fixture by bolt clamping by the rotation of ring flange; When clamping workpiece, base 2 goes to bottom, and workpiece is placed on base 2, makes round boss 5 be buckled in centering in workpiece downside endoporus, and clamp arm 7 is pressed from both sides, and groove is buckled on bolt 8, screws nut 9.
