Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1
As shown in Figure 1, a kind of structural representation of pull-down alignment pin fixture of processing belt hole workpiece, pull-down alignment pin fixture comprises jig main body and Power Component.
Described jig main body is made up of round pin seat 1, alignment pin 2, spring 3, locking nut 4, connecting rod A5, connecting rod B6; Described Power Component is made up of hydraulic pump 7, positioning hydraulic oil circuit 8, pull-down hydraulic oil circuit 9.
Described alignment pin 2 is sleeved in round pin seat 1, and with round pin seat 1 matched in clearance, its bottom is provided with the screw thread matched with locking nut 4, and by screw thread by fixing bottom locking nut 4 and alignment pin 2; Described spring 3 is sleeved on connecting rod A5, forms matched in clearance, and the end thereof contacts with outstanding column structure of spring 3 one end and connecting rod A5, its other end contacts with alignment pin 2 bottom faces; Described connecting rod A5 is arranged on bottom alignment pin 2, the groove matched in clearance in the other end with outstanding column structure of connecting rod A5 and locking nut 4; Described round pin seat 1 is bolted and is arranged on jig plate.Described connecting rod B6 one end and connecting rod A5 are threaded connection, and the other end is arranged in hydraulic pump 7, and with hydraulic pump 7 interference fits.
Described positioning hydraulic oil circuit 8, pull-down hydraulic oil circuit 9 connect external hydraulic station, carry out oil transportation by external hydraulic station to oil circuit, realize athletic performance of the present utility model.
Fig. 2 is a kind of pull-down alignment pin fixture positioning states schematic diagram of processing belt hole workpiece, as shown in Figure 2, the pull-down alignment pin fixture position fixing process of processing belt hole workpiece is as follows: by CNC instruction, external hydraulic station pulls down hydraulic circuit 9 input hydraulic pressure oil, to positioning hydraulic oil circuit 8 output hydraulic pressure oil.Because external hydraulic station pulls down hydraulic circuit 9 input hydraulic pressure oil, connecting rod B6 is caused to move upward to positioning hydraulic oil circuit 8 output hydraulic pressure oil; Because connecting rod B6 and connecting rod A5 is threaded connection, connecting rod A5 moves upward.Due to connecting rod A5 and spring 3 matched in clearance, and spring 3 one end and connecting rod A5 mono-end contact, spring 3 is extruded, and produces active force upwards.Again because spring 3 contacts with alignment pin 2, alignment pin 2 is moved upward by the upwards active force of spring 3; Due to alignment pin 2 and round pin seat 1 matched in clearance, alignment pin 2 finally stretches out round pin seat 1.Finally, positioned by alignment pin 2 pairs of workpiece.Form the pull-down alignment pin fixture positioning states of processing belt hole workpiece.
Fig. 3 is a kind of pull-down alignment pin fixture pull-down state schematic diagram of processing belt hole workpiece, as described in Figure 3, pull-down alignment pin downdraw process is as follows: after fixture loaded onto by workpiece, instruction is produced by CNC, fixture clamping mechanism operates, clamp system is Workpiece clamping, and pull-down alignment pin starts action.External hydraulic station, to positioning hydraulic oil circuit 8 input hydraulic pressure oil, pulls down hydraulic circuit 9 output hydraulic pressure oil.External hydraulic station, to positioning hydraulic oil circuit 8 input hydraulic pressure oil, pulls down hydraulic circuit 9 output hydraulic pressure oil and causes connecting rod B6 to use downwards; Because connecting rod B6 and connecting rod A5 is threaded connection, connecting rod A5 moves downward; Due to connecting rod A5 and locking nut 4 matched in clearance, and connecting rod A5 part face contacts with locking nut 4 and connects, and therefore locking nut 4 moves downward; Because locking screw 4 is threaded with alignment pin 2, alignment pin 2 moves downward.Due to alignment pin 2 and round pin seat 1 matched in clearance, alignment pin 2 finally stretches into round pin seat 1.CNC can process locating hole.The pull-down alignment pin fixture completing processing belt hole workpiece is drop-down.
