Background technology
Existing lathe adopts the shaft shoulder or ringfeder location conventionally for weld yoke and yoke two earhole jump-ring slot processing tools, causes inconvenience is installed, and location is inaccurate, and machining accuracy is difficult to guarantee.
Utility model content
The utility model is in order to solve defect and the deficiency existing in above-mentioned prior art, provides a kind of simple in structure, easy for installation, accurate positioning, clamping easily for the frock clamp of weld yoke and yoke two earhole jump-ring slots processing.
The technical solution of the utility model: a kind of frock clamp for weld yoke and yoke two earhole jump-ring slot processing, comprise base and be fixed on two workpiece locating pieces on base, two workpiece locating pieces are respectively the first V-type seat and the second V-type seat, described the second V-type seat is for positioning workpieces earhole end, the first V-type seat is for the positioning workpieces other end, the top of described the second V-type seat is provided with the upper holder block that coordinates the second V-type seat, distance between described the first V-type seat and the second V-type seat matches with the length of workpiece, the width of described upper holder block is less than the distance between workpiece two earholes, this frock clamp also comprises the mandrel through workpiece two earholes, described mandrel length matches with the distance between workpiece two earholes, mandrel middle part is pressed on described upper holder block top.
Preferably, described mandrel middle part downside has step, and described length of bench is less than mandrel length, the matched in clearance of step width and the second V-type seat, described mandrel two ends and workpiece two earhole matched in clearance.
Preferably, the distance of the length of described mandrel between the distance between workpiece two earhole inner sides and workpiece two earhole outsides.
The beneficial effects of the utility model are as follows: the utility model is simple in structure, clamping workpiece is convenient, accurate positioning is reliable, are specifically designed to the processing of weld yoke and yoke two earhole jump-ring slots.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1. upper holder blocks in figure, 2. the first V-type seat, 3. the second V-type seat, 4. mandrel, 5. base, 6. jump-ring slot, 7. workpiece.
the specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail,
As shown in Figure 1, a kind of frock clamp for weld yoke and yoke two earhole jump-ring slot processing, comprise base 5 and be fixed on two workpiece locating pieces on base 5, two workpiece locating pieces are respectively the first V-type seat 2 and the second V-type seat 3, the second V-type seat 3 is for positioning workpieces earhole end, the first V-type seat 2 is for the positioning workpieces other end, the top of the second V-type seat 3 is provided with the upper holder block 1 that coordinates the second V-type seat 3, distance between the first V-type seat 2 and the second V-type seat 3 matches with the length of workpiece, the width of upper holder block 1 is less than the distance between workpiece two earholes, this frock clamp also comprises the mandrel 4 through workpiece two earholes, mandrel 4 length match with the distance between workpiece two earholes, mandrel 4 middle parts are pressed on upper holder block 1 top.Mandrel 4 middle part downsides have step, and length of bench is less than mandrel 4 length, the matched in clearance of step width and the second V-type seat 3, mandrel 4 two ends and workpiece two earhole matched in clearance.The distance of the length of mandrel 4 between the distance between workpiece two earhole inner sides and workpiece two earhole outsides.
Operation principle of the present utility model:
Mandrel 4 is placed on the second V-type seat 3 through after workpiece two earholes, and workpiece 7 other ends ride on the first V-type seat 2, and upper holder block 1 withstands mandrel 4, thereby has compressed mandrel 4 and workpiece simultaneously.The second V-type seat 3 and mandrel 4 have been realized the location, left and right of workpiece, and the first V-type seat 2 has guaranteed the location, front and back of workpiece, and two kinds of location combine, thereby realize the accurate location of workpiece.
Workpiece clamping mode structure of the present utility model, makes accurate work piece positioning reliable, and clamping workpiece is convenient, is beneficial to operation, enhances productivity, and is specifically designed to the processing of weld yoke and yoke two earhole jump-ring slots 6.
Above-described is only preferred embodiment of the present utility model; should be understood that; for those of ordinary skill in the art; do not departing under the prerequisite of core technology feature of the present invention; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
