Abstract
The internal grinder clamping device of 4 chucks and scroll chuck, comprise grinding machine spindle, scroll chuck, it is characterized in that: install in internal grinder headstock and be placed in spindle flange dish axial side with the spindle flange dish of integrated spindle axis, the anchor ring of 4 chucks, 4 chuck land inwalls settle scroll chuck, tighten together with the fastening screw pit of bolt by three; Turn the lock screw on 4 chuck perimeter, make it vertically hold out against the dish body outer wall of scroll chuck, make scroll chuck centering, by workpiece end face levelling, inner circle centering.Advantage: when clamping force declines, the lock screw just on 4 chucks has worn and torn, and can change separately, not need to change whole jig, can ensure to continue to provide reliable and stable clamping force to lock screw.Save replacing chuck, save production cost.
Description
Technical field
The utility model belongs to plant equipment and manufactures field, relates to the clamping device of internal grinder folder scroll chuck, specifically refers to 4 chucks replacement chucks.
Background technology
In the clamping device of internal grinder, usually can use chuck arrange in pairs or groups with scroll chuck together with use, see Fig. 4, namely by chuck card scroll chuck, the scroll chuck holding workpiece fixing with grinding machine.Owing to using the wearing and tearing produced, scroll chuck and chuck all need whole updating substantially every year, change once, and Productive statistics cost is large.
Chuck (Fig. 4) whole frock is before bulky, and structure bulky, uses loaded down with trivial details.Chuck is made up of a chuck body, 4 movable gripper jaws and 4 cover gripper jaw driving mechanisms.Gripper jaw is evenly distributed on chuck circumferentially, and chuck sidewall is provided with equally distributed 4 tighten the screws, and tighten the screws is connected with gripper jaw.Chuck there is a set of guide thread below each gripper jaw, guide thread is driven and 1 gripper jaw being connected of correspondence is close or exit to center with it when adjusting and tightening screw, each gripper jaw is independent activities to chuck body center position, in order to clamp the irregular workpiece of profile.During chuck card scroll chuck, in the circle formed the gripper jaw that the dish body of scroll chuck sticks into chuck, tighten 4 tighten the screws of chuck, the dish body of the gripper jaw clamping scroll chuck of chuck.
Screw is tightened in long-time use can cause thread abrasion in chuck, and after wearing and tearing, chuck screw thread produces gap, chuck precision reduces, and at this moment needs integral replacing chuck.
Summary of the invention
The purpose of this utility model is the clamping device providing a kind of internal grinder 4 chucks and scroll chuck, replace chuck with 4 chucks, be connected with scroll chuck, simple and efficient, rear of use wearing and tearing need change adjustment lock screw, save production cost.
The utility model implementation is as follows: the internal grinder clamping device of 4 chucks and scroll chuck, comprise grinding machine spindle, scroll chuck, it is characterized in that: the spindle flange dish with integrated spindle axis is installed in internal grinder headstock, the anchor ring of 4 chucks is placed in spindle flange dish axial side, 4 chuck land inwalls settle scroll chuck, tighten together with the fastening screw pit of bolt by three; Described 4 chucks are the annular table having endoporus, loop has 6 equally distributed fastening screw pits, ring outer rim is sidewall, ring wall is evenly distributed with the adjustment lock screw of four screwed holes and pairing, ring wall end face is evenly distributed with 3 gap, and 4 chuck land walls encase scroll chuck barrel, turn the lock screw on 4 chuck perimeter, make it vertically hold out against the dish body outer wall of scroll chuck, make scroll chuck centering, by workpiece end face levelling, inner circle centering.
The utility model compared with prior art has the following advantages: when clamping force declines, lock screw just on 4 chucks has worn and torn, can change lock screw separately, not need to change whole jig, can ensure to continue to provide reliable and stable clamping force.Just replace chucks with 4 chucks by the design, scroll chuck does not change, and avoids upgrading, changes the trouble that more multi-part brings, can find out the production cost saving of saving replacing chuck and bringing from volume.

Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.As shown in Figure 1, the internal grinder clamping device of 4 chucks and scroll chuck, comprise internal grinder spindle flange dish 1, chuck 2 and scroll chucks 3 at 4, when it is characterized in that assembling, the spindle flange dish 1 be integrated with main shaft is installed in internal grinder headstock, screw base ring side is had by 4 chucks 2 to be bolted on internal grinder spindle flange dish 1, again scroll chuck 3 barrel is placed in 4 chuck 2 land, and with bolt through the screw at the bottom of scroll chuck 3 and 4 chuck 2 ends circles fixing, tighten together with spindle flange dish 1 simultaneously; Turn the adjustment lock screw 22 centering scroll chuck on 4 chuck cylindrical walls or workpiece end face.Described 4 chucks 2 are for there being the annular table of endoporus, loop has 6 equally distributed fastening screw pits 23, ring outer rim is sidewall, ring wall is evenly distributed with the adjustment lock screw 22 of four screwed holes and pairing, ring wall end face is evenly distributed with 3 gap, 21, four chuck 2 land inwalls and encases scroll chuck 3 barrel.The shape of 4 chucks 2: see Fig. 2,3, center is the land of macropore, land periphery T-Ring wall, and ring wall also has four screws settling adjustment lock screw, ring wall end face has the three equally distributed gap in place; Land endoporus can hold scroll chuck 3 barrel.The shape of spindle flange dish 1: see Fig. 5, namely spindle end in internal grinder headstock is the disc flange with integrated spindle axis, disc flange circle centre position and the same diameter of main shaft, its external diameter with 4 chuck 2 is equal with scroll chuck 3 external diameter and there are three bolts hole equidistantly distributed nearly periphery.
The shape of scroll chuck 3: tubular, barrel diameter are less than the land aperture of 4 chucks 2, circle at the bottom of cylinder has three the equidistantly bolt hole of distribution and the claws of three equidistant distributions of dislocation.
Described adjustment lock screw 22 be evenly distributed on 4 chucks circumferentially and the outer disc body vertically held out against in scroll chuck 3.
Described scroll chuck 3 nozzle end is elastic opening, respectively three place's cylindrical ring wall gap 21 of corresponding 4 chucks 2.
The Job Operations step of the clamping device of the utility model internal grinder is:
Steps A, in four screwed holes of 4 chuck 2 cylindrical walls, place the adjustment lock screw 22 of pairing.By Fig. 2,4 chucks 2 and scroll chuck 3 are tightened together by fastening screw pit 23 with ring flange 1 bolt.
Step B, adjustment screw 22 to be unclamped, the dish body of scroll chuck 3 is sticked into inside 4 chuck 2 main bodys in circle, and adjustment screw 22 is held out against the outer wall dish body of scroll chuck 3, simultaneously by scroll chuck 3 end face centering.
Step C, when carrying out grinding work piece, with scroll chuck 3 clamping workpiece, hole and end face in the adjustment screw 22 centering workpiece of 4 chucks 2.
As mentioned above, then the utility model can be realized well.
