Abstract
The invention provides a press fitting device based on an eccentric wheel structure. The press fitting device sequentially comprises a press fitting plate, four guide shafts, two transverse connection rods, two vertical connection rods, two eccentric wheel mechanisms and an input shaft from top to bottom. According to the press fitting device, the input shaft rotates to drive the eccentric wheel mechanisms to rotate, the eccentric wheel mechanisms convert rotational motions into straight reciprocating motions of a mounting plate, a corresponding press fitting structure is installed on the mounting plate, and press fitting in the vertical direction can be realized. The press fitting device based on the eccentric wheel structure uses a mechanical structure for providing power in the vertical direction, is simple in structure, is applicable to work with a low requirement for press fitting force and with a high press fitting rate, and is stable in work and durable.
Description
Technical field
The invention belongs to press-loading apparatus, especially relates to a kind of press-loading apparatus based on eccentric wheel structure.

Summary of the invention
The problem that the invention will solve is to provide and a kind ofly moves steadily, the power press-loading apparatus based on eccentric wheel structure reliably, is particularly useful for pressure assembling force demand less and press-fit during speed works efficiently.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: a kind of press-loading apparatus based on eccentric wheel structure, comprises the pressing plate setting gradually, four axis of guides, two tranverse connecting rods, two vertical connecting rods, two eccentric mechanisms and a power shaft from top to bottom; The rectangular edge of described pressing plate is horizontally disposed with its bottom surface corner location the axis of guide is vertically set; Tranverse connecting rod two ends are connected with the lower end of two axis of guides respectively, and this tranverse connecting rod middle part is connected with vertical connecting rod, and this vertical connecting rod lower end is connected with eccentric mechanism; The axis of power shaft is along being horizontally disposed with, and two eccentric mechanisms are separately positioned on power shaft two ends.
Described eccentric mechanism comprises the runner that is coaxially arranged on described power shaft end, on this runner periphery, away from shaft core position, be fixedly installed runner connecting shaft, the axis of runner connecting shaft and the axis of power shaft be arranged in parallel, and this runner connecting shaft is connected with the lower end of described vertical connecting rod by the first pipe connecting piece.
Described runner is circular, and its home position is sleeved on described power shaft end.
Described tranverse connecting rod middle part is provided with pitman shaft, between this pitman shaft and described vertical connecting rod, the second pipe connecting piece is set, and this second pipe connecting piece one end is sleeved on pitman shaft, and the other end is connected with described vertical connecting rod upper end.
On described four axis of guides, be respectively installed with linear bearing; Linear bearing both can guarantee the steady of axis of guide motion, can guarantee vertical precision again.
Owing to having adopted technique scheme, this device rotatablely moves by power shaft, drives eccentric mechanism to rotate, and eccentric mechanism is transformed into gyration the straight reciprocating motion of installing plate, corresponding press mounting structure is installed on installing plate, just can be realized press-fiting in the vertical direction; This device is a kind of mechanism that utilizes frame for movement that vertical direction power is provided, simple in structure, is applicable to pressure assembling force demand less and press-fit during speed works efficiently, and this device working stability is durable in use.
Advantage and good effect that the invention has are: 1) by four axis of guides, two tranverse connecting rods, two vertical connecting rods, two eccentric mechanisms, make the gyration of power shaft change pressing plate straight reciprocating motion vertically into, both guaranteed straight reciprocating motion steadily, fast, guaranteed again straight reciprocating motion perpendicularity; 2) on four axis of guides, be respectively installed with linear bearing, linear bearing both can guarantee the steady of axis of guide motion, had guaranteed again the vertical precision of axis of guide motion; 3) be coaxially arranged on the runner of described power shaft end, on this runner periphery, away from shaft core position, be fixedly installed runner connecting shaft, described runner is that circular its home position is sleeved on described power shaft end, and the gyration that has further improved power shaft changes the stationarity of pressing plate straight reciprocating motion vertically into; That the present invention has advantages of is simple in structure, motion steadily, power is reliable, straight reciprocating motion speed is fast, precision is higher.
