Description
Technical Field
The utility model relates to the technical field of engine oil filter cores, in particular to a drawing force positioning device for an end cover of an engine oil filter core.
Background
The engine oil filter element is an engine oil filter, and the engine oil filter has the function of filtering impurities, colloid and water in engine oil and conveying clean engine oil to all lubrication parts. In order to reduce the friction resistance between the relative movement parts in the engine and reduce the abrasion of parts, engine oil is continuously conveyed to the friction surfaces of the movement parts to form a lubricating oil film for lubrication. The engine oil itself contains certain amounts of gum, impurities, moisture and additives. Meanwhile, during the working process of the engine, metal abrasive dust is carried in, sundries in the air are introduced, engine oil oxides are generated, and the sundries in the engine oil are gradually increased. If the engine oil is not filtered and directly enters the lubricating oil way, sundries contained in the engine oil can be brought into the friction surface of the kinematic pair, abrasion of parts is accelerated, and the service life of the engine is reduced.
In the machining process of the engine oil filter core, an end cover needs to be welded, after the end cover is welded, a tensile testing machine needs to be used for testing the welding strength of the end cover, the flexibility of a drawing force positioning device used in the welding strength testing in the prior art is not good enough, the engine oil filter core cannot be suitable for clamping products with various different outer diameters, the self-locking is not firm enough, and the end cover of the filter core is easy to damage.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a device for positioning the drawing force of an end cover of an engine oil filter element.
The utility model is realized by the following technical scheme:
the utility model provides a power positioner is drawn to machine oil filter core end cover, includes long screw rod and three jack catch, is fixed with the connecting block on the head top of long screw rod, opens there is the connecting hole on the connecting block, is fixed with long sleeve at long screw rod surface fixedly connected with, is located long sleeve below at long screw rod lower extreme and is fixed with the support lantern ring, the equipartition has three support boss on the support lantern ring surface, the one end of three connecting rod is articulated respectively to three support boss, the middle lower part of three jack catch is articulated respectively to the other end of three connecting rod the outside of long sleeve around cover respectively have spring and lag.
The inner walls of the long sleeve and the supporting lantern ring are provided with internal threads, and the long screw is in threaded connection with the long sleeve and the supporting lantern ring.
The three clamping claws are Z-shaped clamping claws, the upper end bent hook parts of the three clamping claws face to the outer side, and the lower end bent hook parts of the three clamping claws face to the inner side.
The protective sleeve is a round block, and a center hole for the long sleeve to pass through is formed in the center of the round block.
The utility model has the advantages that: according to the utility model, the pulling force positioning device is fixed on the tensile testing machine, and the engine oil filter core end cover can be locked between the lower ends of the three clamping jaws by pulling the long screw rod upwards, so that the flexibility is good, the self-locking is firm, and the end cover cannot be damaged; through threaded connection, can change different interfaces according to different filter core sizes, the free clamping is applicable to the product clamping of different external diameters, convenient to use.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a front view of the present utility model.
Detailed Description
As shown in fig. 1 and 2, the drawing force positioning device for the engine oil filter core end cover comprises a long screw rod 1 and three clamping claws 2, wherein a connecting block 3 is fixed at the top end of the head of the long screw rod 1, a connecting hole 4 is formed in the connecting block 3, a long sleeve 5 is fixedly connected to the outer surface of the long screw rod 1, a supporting sleeve ring 6 is fixed below the long sleeve 5 at the lower end of the long screw rod 1, internal threads are formed in the inner walls of the long sleeve 5 and the supporting sleeve ring 6, and the long screw rod 1 is in threaded connection with the long sleeve 5 and the supporting sleeve ring 6. Three support bosses 7 are uniformly distributed on the outer surface of the support collar 6, the three support bosses 7 are respectively hinged with one ends of three connecting rods 8, the other ends of the three connecting rods 8 are respectively hinged with the middle lower parts of three clamping claws 2, the three clamping claws 2 are Z-shaped clamping claws, the upper end crotch parts of the three clamping claws 2 face to the outer side, and the lower end crotch parts of the three clamping claws face to the inner side. The outside of long sleeve 5 around cover respectively have spring 9 and lag 10, lag 10 be the circular piece, open at circular piece center has the centre bore that supplies long sleeve 5 to pass, when pulling long screw 1 upwards, long screw 1 pulls connecting rod 8 to the lower extreme of pulling three jack catch 2 presss from both sides the engine oil filter core end cover that lies in between the three jack catch 2, manual push the lag to between the upper end of three jack catch 2, when the engine oil filter core end cover is pressed from both sides to three jack catch 2, the upper end of three jack catch 2 presss from both sides tight lag 10, lag 10 plays spacing effect, prevents to pull to a certain extent, the too tight of jack catch 2 lower extreme clamp, the filter core is pulled apart, the spring plays certain cushioning effect.
The working principle of the utility model is as follows: the method comprises the steps of adjusting the distance between the tensile testing machine equipment and the height of a similar product, installing a drawing force positioning device on the tensile testing machine equipment through a connecting block at the upper end of a long screw 1, placing a welded engine oil filter core end cover between the lower ends of three clamping jaws 2, manually pushing a protective sleeve 10 onto the upper surface, enabling the protective sleeve 10 to be positioned between the upper ends of the three clamping jaws 2, starting equipment, setting parameters for testing, and enabling the lower ends of the three clamping jaws 2 to clamp the engine oil filter core end cover by stretching the screw 1 upwards by the tensile testing machine equipment.
