Abstract
The utility model discloses a clamping device of a resistance annular groove processing machine. A transmission lever drives the respective end cams of two transmission cases of the utility model, and a rolling wheel of a swing arm pushes two main shafts to separate to loosen processed components. When the cams rotate to the low points, springs which are sheathed on the main shafts are used to push the two main shafts to inward move and tightly clamp workpieces. The utility model has the advantages of simple structure, lightens the physical labor intensity of workers, and can not damage the processed components by the clamping force.
Description
The utility model relates to a kind of clamping device, is applicable to the ring-shaped groove mechanical grip workpiece of processing resistance.
How used ring resistance processing equipment clamps part to be processed with pawl formula chuck; During renewal part, the operation spanner is unscrewed jaw earlier, takes out processing parts; Change part to be processed then, part is clamped by spanner; Complex operation, production efficiency are low, also can damage part to be processed (resistance) sometimes.
The utility model purpose is to overcome above-mentioned deficiency to have designed a kind of clamping device with left and right transmission case, respectively is provided with main shaft, wheel piece, edge cam and swing arm in the transmission case and transmits telecontrol equipment; Rotate transmission bar and can realize clamping and unclamping workpiece.
The utility model content respectively is provided with main shaft in two transmission cases, and wheel piece and spring are housed on the main shaft, and spindle nose is equipped with chuck; Be provided with shared transmission bar in two transmission cases, edge cam is housed on it; In between main shaft and transmission bar, be provided with the swing arm holder assembly, the articulated swing arm that has two rollers on it; During the transmission bar rotation, edge cam promotes roller and makes the swing arm swing, when the height point of edge cam contacts with roller, by another roller promotion wheel piece and main shaft two main shafts is moved to separating direction, unclamps workpiece; When the low spot of edge cam contacts with roller, rely on the thrust of spring to make two main shafts move clamping work pieces in opposite directions.
The utility model advantage, thus because the edge cam that the ring-shaped groove processing equipment clamping device of resistance manipulation transmission bar can rotate in the left and right transmission case simultaneously drives swing arm, make their main shaft and chuck disconnected from each other, unclamp part; Or move clamping work pieces in opposite directions; Alleviate labor strength, improved production efficiency; Simultaneously can and select spring according to optimum clamping force manufacturing, can injuring part, guaranteed product quality.
Fig. 1 is the utility model stereogram (part)
Fig. 2 is a vertical view of the present utility model
Below in conjunction with description of drawings the utility model embodiment, the ring-shaped groove processing equipment clamping device of resistance is made up of Left Drive case (10), right transmission case (1), transmission bar (11), roller (2), edge cam (3), swing arm (4), wheel piece (6), spring (5), roller (7), main shaft (8), chuck (9), swing arm holder assembly (12) and transmission bar (11); Transmission case (1) and (10) lining are provided with transmission bar (11), and edge cam (3) is housed on it, are provided with swing arm holder assembly (12) between main shaft (8) and transmission bar (11), the articulated swing arm (4) that has roller (2) and roller (7) on it; During transmission bar (11) motion, edge cam (3) promotes roller (2), makes swing arm (4) swing, when the height point of edge cam (3) and roller (2) when contacting, promote wheel piece (6) and main shaft (8) by roller (7), two main shafts (8) are moved to separating direction, unclamp workpiece; When the low spot of edge cam (3) and roller (2) when contacting, rely on the thrust of spring (5) to make two main shafts (8) move clamping work pieces in opposite directions.Transmission bar (11) drives the edge cam (3) of transmission case (1) and (10) lining simultaneously when rotating; Transmission bar (11) can be whole elongated part, because it is longer, also can make two sections, links together to make with convenient again.Edge cam (3) and transmission bar (11) are for spline is connected, and both can slide relatively flexibly; Swing arm (4) is hinged on the swing arm holder assembly (12), and swing arm holder assembly (12) is fixed on the tank wall of transmission case (1) or (10); Rolling bearing is adopted in roller (2) and (7), and they are hinged on the two ends of swing arm (4) respectively, and wheel piece (6) passes through dowel fixes together with main shaft (8).
Claims (1)
1, a kind of clamping device of processing the ring-shaped groove machinery of resistance is characterized in that the back of two transmission cases (1) and (10) is equiped with common transmission bar (11); Be equiped with main shaft (8) in the front of two transmission cases (1) and (10), chuck (9) is housed on the main shaft (8); Be equiped with rocker arm assembly (12) at the middle part of two transmission cases (1) and (10), articulated rocking arm (4) on it; the articulated roller (2) that is pressed on edge cam (3) of an end of rocking arm (4), the articulated roller (7) that is pressed on wheel piece (6) end face of the other end of rocking arm (4); Spring (5) is loaded between transmission tank wall and the wheel piece (6).
