Abstract
A lever slider mechanism of a numerical control servo high-speed notching machine comprises a push rod, a connecting rod, a large lever, a ball connecting rod and a slider. A punch is fixed on the slider, the lower end of the push rod is connected with a crank shaft, the upper end of the push rod is hinged to one end of the large lever through a back shaft, the other end of the large lever is hinged to the connecting rod of the front shaft, the large lever is connected with a lathe bed through a fulcrum shaft, and the ball connecting rod is connected between the connecting rod and the slider. The lever slider mechanism is characterized in that a clamping slot is arranged at the connected position of the connecting rod and a regulating screw of the ball connecting rod, the opening of the clamping slot is arranged on an end face of the connecting rod, symmetrical central surfaces of the two sides of the clamping slot are intersected with the axis of the regulating screw, and the clamping slot is further provided with a gland matched with the clamping slot. Due to the structure, abrasion of various main components of a toggle lever impacted for a long time can be reduced, the main components can keep stable and not easy to deform, and the service lives of the components are prolonged, and punching precision can be increased.
Description
Technical field
The utility model relates to a kind of lever slide block mechanism of numerical control servo high-speed notching press, especially relates to a kind of lever slide block mechanism of processing the numerical control servo high-speed notching press of motor silicon steel sheet.
Background technology
At present, the process of numerical control servo high-speed notching press is to carry out calibration by indexing mechanism and drive drift by punching mechanism again and finish punching press being positioned at silicon steel on the workbench of numerical control servo high-speed notching press.China Patent No. is the elbow-bar mechanism that 200720034507.4 utility model discloses a kind of numerical control notching press, comprise bent axle, push rod, push rod, fork, connecting rod, ball head connecting rod and the fixing slide block of drift, the lower end of push rod is connected with bent axle, the upper end of push rod is by first side that is connected fork, connecting rod is by second lower end that is connected fork, and fork is provided with axis hole, is provided with the fork axle that is connected with supporter in the axis hole.Can be that the drift one-period is finished twice punching press continuously.According to having following some deficiency in the above-described utility model: one, push rod is that the assembling of segment type is worn and torn push rod easily when work, cause connect loosening.Two, push rod is connected by screw with bent axle, makes push rod when work be connected instability with bent axle, and three, the bulb of ball head connecting rod is fixedly connected in slide block, and bulb is worn and torn easily.Such weak point causes easily that the toggle link slide block mechanism of notching press is easy to wear, yielding, the precision of punching press reduces, and reduce service life.
Summary of the invention
The purpose of this utility model provides a kind of lever slide block mechanism of numerical control servo high-speed notching press, and the push rod and the bulb precision easy to wear, yielding when work, punching press that solve the toggle link slide block of notching press reduce problems such as minimizing in service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lever slide block mechanism of numerical control servo high-speed notching press, comprise push rod, connecting rod, big lever, the ball head connecting rod and the fixing slide block of drift, described push rod lower end is connected with bent axle, the push rod upper end is hinged by rear axle and big lever one end, the other end of big lever is by front axle and rod hinge connection, big lever is connected with lathe bed by fulcrum shaft, ball head connecting rod is connected between connecting rod and the slide block, it is characterized in that: a side of the adjusting screw(rod) junction of described connecting rod and ball head connecting rod is provided with clamping slot, the opening of described clamping slot is on the end face of connecting rod, the symmetrical centre face of two sides of described clamping slot and adjusting screw(rod) axes intersect also are provided with the gland that is complementary with clamping slot on the described clamping slot.
Described push rod is the overall structure of disposable casting.
Described push rod lower end is connected with bent axle and is provided with single-row needle bearing.
Described push rod upper end is provided with single-row needle bearing by being provided with single-row needle bearing between rear axle and the big lever between front axle and the connecting rod.
Beneficial effect of the present invention:, single-row needle bearing is set between the motive position connects owing to adopt the above-mentioned slide block and the syndeton of ball head connecting rod.Push rod each main parts when impacting for a long time can be reduced wear, keep stable, not yielding, and the service life of improving parts, the precision of punching press also can be improved.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
