Abstract
The utility model aims at overcoming the problem that bounce of internal threads of a commonly-used power machine crankshaft tapping clamp in the prior art cannot be ensured after tapping is performed and accordingly out-of-tolerance is frequent, and provides a commonly-used power machine crankshaft tapping clamp. The commonly-used power machine crankshaft tapping clamp comprises a base plate, an installing plate, a support, two V-shaped positioning blocks and a movable hasp. The support is processed into a right triangle and then vertically welded on the base plate, and the installing plate is vertically installed on the base plate and is fixedly connected with the support. The V-shaped positioning blocks are identical in size and shape, an upper V-shaped positioning block and a lower V-shaped positioning block are fixedly installed on the installing plate, the size and the positions of the V-shaped positioning blocks are respectively matched with the fly wheel end rod portion and the output end rod portion of a crankshaft, and a connecting line formed by the tip portions of two V-shaped positioning blocks is perpendicular to the base plate. The movable hasp is arranged between the upper V-shaped positioning block and the lower V-shaped positioning block, is fixedly connected with the installing plate and comprises a fixing end and a moving end, wherein the moving end are matched with a crank throw in size and in shape. The commonly-used power machine crankshaft tapping clamp ensures the inner threads not to cause the bounce after the tapping is performed and avoids an out-of-tolerance phenomenon.
Description
Technical field
The utility model relates to a kind of tapping clamp, particularly a kind of general power machine crank shaft tapping clamp.
Background technology
Bent axle is one of most important part in the logical machine, its function is that the straight reciprocating motion with piston changes gyration into, and output torque, drive the external equipment that connects with it, drive in addition the controlling organizations such as valve actuating mechanism, ignition mechanism, speed adjusting gear.
Usually, a side of bent axle is flywheel end bar section, and main connector is engine flywheel, and the middle part is crank throw, is also referred to as rod journal, mainly links to each other with connecting rod, and opposite side is output bar section, main outside, the output engine power of connecting.In the prior art, the general power machine crank shaft tapping clamp comprises scroll chuck, when crankshaft output end bar section is carried out the endoporus tapping, the flywheel end bar section of general power machine crank shaft is clamped with scroll chuck, then with the screw thread screw tap output bar section of bent axle is carried out hand tapping, because bent axle is longer, tapping positional distance scroll chuck anchor point is far away, and bent axle has slight swing during tapping.Obviously, prior art general power machine crank shaft tapping clamp exists after the tapping internal thread bad assurance of beating, overproof frequently problem.
Summary of the invention
For overcoming after the tapping that prior art general power machine crank shaft tapping clamp exists the internal thread bad assurance of beating, overproof frequently problem the utility model proposes a kind of general power machine crank shaft tapping clamp.The utility model general power machine crank shaft tapping clamp, comprise base plate, installing plate, support, V-type locating piece and movable hasp, support is vertically welded on the base plate after being processed into right angled triangle, the installing plate at right angle setting is fixedly connected with on base plate and with support, wherein, the V-type locating piece is identical two of size and shape, two V-type locating pieces are fixedly installed on the installing plate up and down, and size and position and be complementary with flywheel end bar section and the output bar section of bent axle respectively, the tip connecting line of two V-type locating pieces is vertical with base plate, movable hasp is arranged at up and down between two V-type locating pieces and with installing plate and is fixedly connected with, movable hasp comprises stiff end and movable end, and size and shape and the crank throw of described movable end are complementary.
Further, the utility model general power machine crank shaft tapping clamp is provided with bearing below the V-type locating piece, and bearing is two and is symmetricly set in the installing plate bottom.
The useful technique effect of the utility model general power machine crank shaft tapping clamp is to guarantee that internal thread does not produce after the tapping to beat, and has avoided off-gage phenomenon.
Description of drawings
Accompanying drawing 1 is the structural representation of prior art general power machine crank shaft tapping clamp;
Accompanying drawing 2 is the structural representation of the utility model general power machine crank shaft tapping clamp;
Accompanying drawing 3 is the right view of accompanying drawing 2.
Below in conjunction with drawings and the specific embodiments the utility model general power machine crank shaft tapping clamp is described further.
The specific embodiment
Accompanying drawing 2 is the structural representation of the utility model general power machine crank shaft tapping clamp, and accompanying drawing 3 is the right view of accompanying drawing 2, among the figure, and 1 base plate, 2 is installing plate, and 3 is support, and 4 is the V-type locating piece, and 5 is movable hasp, 6 is bearing, and 501 is stiff end, and 502 is movable end.As seen from the figure, the utility model general power machine crank shaft tapping clamp, comprise base plate 1, installing plate 2, support 3, V-type locating piece 4 and movable hasp 5, support 3 is vertically welded on the base plate 1 after being processed into right angled triangle, installing plate 2 at right angle settings are fixedly connected with on base plate 1 and with support 3, wherein, V-type locating piece 4 is identical two of size and shape, two V-type locating pieces 4 are fixedly installed on the installing plate 2 up and down, and size and position and be complementary with flywheel end bar section and the output bar section of bent axle respectively, the tip connecting line of two V-type locating pieces 4 is vertical with base plate 1, movable hasp 5 is arranged at up and down between two V-type locating pieces 4 and with installing plate 2 and is fixedly connected with, movable hasp 5 comprises stiff end 501 and movable end 502, and size and shape and the crank throw of described movable end 502 are complementary.In order to play better fixed effect, the utility model general power machine crank shaft tapping clamp is provided with bearing 6 below V-type locating piece 4, and bearing 6 is two and is symmetricly set in installing plate 2 bottoms.When crankshaft output end bar section is carried out the endoporus tapping, the flywheel end bar section of general power machine crank shaft and output bar section are leaned against up and down on two V-type locating pieces 4, then crank throw is placed between the stiff end 501 and movable end 502 of movable hasp 5, movable end 502 is walked around crank throw to be buckled on the stiff end 501, like this, bent axle well can be fixed on the general power machine crank shaft tapping clamp of the present utility model by two V-type locating pieces 4 and movable hasp 5, and be difficult for producing and rock, and, the utility model is provided with bearing 6 below V-type locating piece 4, better played the effect to the fixing and support of V-type locating piece 4, match with support 3, when tapping, more can not produce and rock.Then, with the screw thread screw tap output bar section of bent axle is carried out tapping, V-type locating piece 4 anchor points of tapping positional distance top are nearer, and internal thread does not produce beats.Compared with prior art, change scroll chuck into mode that V-type locating piece and movable hasp match, obviously, locating effect is better, and when using the screw thread screw tap to carry out tapping, internal thread does not produce beats, and has avoided off-gage phenomenon.
