Abstract
Press reaming frock is equipped with the power cylinder including the press support on the press support. And a reaming joint is fixed at the end of the piston rod of the press machine extending downwards. The middle part of the bottom plate of the press machine support is provided with a support module. The support module is also provided with a containing hole, and the hole expanding rod, the blank hole and the containing hole of the hole expanding joint correspond to the positions of the hole expanding rod, the blank hole and the containing hole. The power cylinder may be a pneumatic cylinder. The edge of the bottom plate of the press machine bracket is provided with a pressing claw. The effect of this device is exactly to utilize stamping force, with blank hole bending (like fig. 3 behind the reaming), and the effective length requirement of screw thread can be satisfied promptly to crooked back thickness, can not increase the cost again.
Description
Technical Field
The utility model belongs to the machining tool field, in particular to press reaming frock.
Background
When PT threads for sealing are required to be machined on a blank, the thickness of the blank cannot guarantee the effective length of the threads, and if the thickness of the blank is increased, unnecessary cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a press reaming frock, crooked (like fig. 3 behind the reaming) blank hole, crooked back thickness can satisfy the effective length requirement of screw thread promptly, can not the incremental cost again.
The technical scheme is as follows:
press reaming frock is equipped with the power cylinder including the press support on the press support.
The technical key points are as follows:
and a reaming joint is fixed at the end of the piston rod of the press machine extending downwards.
The middle part of the bottom plate of the press machine support is provided with a support module.
The support module is also provided with a containing hole, and the hole expanding rod, the blank hole and the containing hole of the hole expanding joint correspond to the positions of the hole expanding rod, the blank hole and the containing hole.
The power cylinder may be a pneumatic cylinder. The edge of the bottom plate of the press machine bracket is provided with a pressing claw.
The advantages are that:
the effect of this device is exactly to utilize stamping force, with blank hole bending (like fig. 3 behind the reaming), and the effective length requirement of screw thread can be satisfied promptly to crooked back thickness, can not increase the cost again.
Drawings

Fig. 2 is a cross-sectional view AA of fig. 1 (before reaming).
Fig. 3 is a schematic diagram of the next step of reaming the structure of fig. 2.
Fig. 4 shows the workpiece after machining.
The press machine comprises a press machine support 1, a power cylinder 2, a press machine piston 3, a press machine push rod 4, a press machine piston rod 5, a pressing plate 6, a reaming joint 7, a supporting module 8, a pressing claw 9, a blank piece 10, a blank piece hole 11, a counter bore 12, an inner flanging 13, a connecting seat 14, a reaming rod 15, a reaming 16 and a containing hole 17.
Detailed Description
9 press reaming frock, including press support 1 (the press is from taking).
The press machine bracket 1 is provided with a power cylinder 2 (a cylinder, the press machine is provided with).
A press piston 3 (provided by a press) is arranged in the power cylinder 2.
A press push rod 4 (the press is arranged) is arranged above the press piston 3.
A press piston rod 5 is arranged below the press piston 3.
The cylinder body of the power cylinder 2 is vertically fixed on the press machine bracket 1 through a pressure plate 6 (provided by the press machine) at the lower edge.
The end that press piston rod 5 stretched out downwards is fixed with reaming joint 7, and 14 screw threads of connecting seat of reaming joint 7 cooperate and are connected with press piston rod 5, can replace into different specifications.
The diameter of the hole expanding rod 15 is larger than that of the blank hole 11, so that after the hole expanding rod 15 expands the blank hole 11, the inner flanging 13 at the position of the blank hole 11 is provided with enough length for manufacturing threads, and the diameter of the expanding hole 16 also meets the requirement.
The middle part of the bottom plate of the press machine bracket 1 is provided with a supporting module 8 (for positioning and supporting).
A blank 10 is arranged above the support module 8, the edge of the blank 10 being fixed by the press claw 9.
A counter bore 12 is formed in the middle of the supporting module 8, the counter bore 12 is used for connecting the supporting module 8 with a bottom plate of the press machine support 1 through a hexagon socket head cap screw, and the supporting module 8 is fixed.
The lower part of the supporting module 8 is provided with a boss 18 which corresponds to the groove of the bottom plate of the press machine bracket 1 for limiting.
The support module 8 is further provided with a receiving hole 17, and the reaming rod 15 and the receiving hole 17 correspond to the blank hole 11 in position.
The edge of the bottom plate of the press machine support 1 is provided with a plurality of pressing claws 9, and threaded rods of the pressing claws 9 are fixed on the bottom plate of the press machine support 1 to fix a blank 10.
The piston rod 5 of the press machine drives the hole expanding rod 15 of the hole expanding joint 7 to expand the blank hole 11 downwards, the downward inner flanging 13 is expanded at the blank hole 11, the positions of the inner flanging 13, the hole expanding rod 15 and the accommodating hole 17 are corresponding, and after hole expansion, threads are machined in the inner flanging 13 of the hole expanding 16, so that the effective length of the threads is ensured.
