Ring flange vehicle clamper
Technical field
The present invention relates to machinery manufacturing technology field, especially a kind of fixture for ring flange processing.
Background technology
Ring flange is a kind of connector of extensive use, the cylinder 93 transverse to ring flat-plate body 92 that a kind of ring flange 9 as shown in Figure 1 and Figure 2 includes ring flat-plate body 92 and stretches out from ring flat-plate body 92 centre bore 91; Because ring flange plays the connection function of two parts, therefore the requirement on machining accuracy of its centre bore is higher, at present, the processing of ring flange axis hole 91 is that the Workpiece clamping pressing plate by having the trip bolt be connected with boring table completes and locates and clamp, this clamping tool also exists an often processing ring flange in process of production and all needs manually to repeat remover-and-replacer, cause clamping complicated, the problem that production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ring flange vehicle clamper, and it is complicated that this fixture can solve existing ring flange processing and loading clamp, the problem that production efficiency is low.
In order to solve the problem, the technical solution adopted in the present invention is: this fixture comprises the terminal pad that one end is provided with taper shank, Workpiece clamping seat and the cylinder be connected with Work-sheet pressing plate by hinge plate is respectively equipped with at the end face of described terminal pad, described Workpiece clamping seat has the connecting plate which is provided with pin crossed out, described Work-sheet pressing plate offers irregularly-shaped hole, described pin is installed in described irregularly-shaped hole, described Workpiece clamping seat is provided with two relative Workpiece clamping cards.
In above-mentioned ring flange vehicle clamper technical scheme, technical scheme can also be more specifically: described Work-sheet pressing plate is at least two, described Work-sheet pressing plate all offers irregularly-shaped hole, all be coated with described pin in described irregularly-shaped hole, described Work-sheet pressing plate is connected with respective described hinge plate respectively by the lever be installed on described Workpiece clamping seat.
Further: described Workpiece clamping card includes dop portion and which is provided with the connecting portion of pin, the pin of described connecting portion is installed in described irregularly-shaped hole, the link of described dop portion and described connecting portion offers the cavity of setting-in stop screw and spring, and described spring housing is contained on the screw rod of stop screw.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to being respectively equipped with Workpiece clamping seat and the cylinder be connected with Work-sheet pressing plate by hinge plate at the end face of terminal pad, Workpiece clamping seat has the connecting plate which is provided with pin crossed out, Work-sheet pressing plate offers irregularly-shaped hole, pin is installed in irregularly-shaped hole, Workpiece clamping seat is provided with two relative Workpiece clamping cards; Add man-hour, when the telescopic arm of cylinder bounces back downwards, hinge plate one end is moved downward, drive clamping card and Work-sheet pressing plate to be compressed from sidewall clamping and upper end by ring flange simultaneously, when processing is completed, telescopic arm protrudes upward and drives clamping card and Work-sheet pressing plate to be unclamped by ring flange simultaneously, and its clamping is simple, be suitable for producing in enormous quantities, not only having saved the production time also substantially increases production efficiency.
2, due to Work-sheet pressing plate all offering irregularly-shaped hole, all be coated with described pin in irregularly-shaped hole, Work-sheet pressing plate is connected with respective hinge plate respectively by the lever be installed on Workpiece clamping seat, can make Work-sheet pressing plate, there is activity surplus, can compress and unclamp.
3, because Workpiece clamping card includes dop portion and which is provided with the connecting portion of pin, the pin of connecting portion is installed in irregularly-shaped hole, the link of dop portion and connecting portion offers the cavity of setting-in stop screw and spring, spring housing is contained on the screw rod of stop screw, and its spring force can make dop portion follow the action of cylinder and unclamped by dop or clamp.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
As Fig. 3, Fig. 4, ring flange vehicle clamper shown in Fig. 5, comprise the terminal pad 7 that one end is provided with taper shank 10, Workpiece clamping seat 5 is respectively equipped with at the end face of terminal pad 7, Workpiece clamping seat 5 is coated with two levers be oppositely arranged 3, lever 3 one end is all hinged with Work-sheet pressing plate 1 by hinge 13, the other end of lever 3 is hinged with the external part of cylinder 6 respectively by respective hinge plate 4, Workpiece clamping seat 5 has the connecting plate 51 which is provided with pin 11 crossed out, Work-sheet pressing plate 1 offers irregularly-shaped hole 12, pin 11 is installed in irregularly-shaped hole 12, the upper end of Workpiece clamping seat 5 is provided with two relative Workpiece clamping cards 2, Workpiece clamping card 2 includes dop portion 22 and which is provided with the connecting portion 21 of pin, the pin of connecting portion 21 is installed in irregularly-shaped hole 12, the link of dop portion 22 and connecting portion 21 offers the cavity of setting-in stop screw 23 and spring 24, and spring 24 is sleeved on the screw rod of stop screw 23,
Its processing method is as follows:
A, clamps: the taper shank 10 of ring flange vehicle clamper is contained in the spindle hole of lathe;
B, dress workpiece: the outer wall of ring flange 9 cylinder 93 is connected in Workpiece clamping card 2, the lower end of ring flange 9 ring flat-plate body 92 and the upper end of Workpiece clamping card 2 are abutted against, and by the central point of centre bore 91 to be processed on ring flat-plate body 92 and the dead in line of taper shank 10; And respectively Work-sheet pressing plate 1 is placed in ring flange upper end;
C, start lathe, ring flange clamps by clamping card and Work-sheet pressing plate simultaneously, starts lathe, and employing drill bit carries out Drilling operation to centre bore 91, then adopts reamer to ream to the centre bore 91 completing boring;
D, closedown lathe, ring flange unclamps by clamping card and Work-sheet pressing plate simultaneously, takes out ring flange and get final product.
