Abstract
Three-jaw platform formula presss from both sides tight frock, and the interlock push rod is worn to be equipped with by bottom plate support clearance fit. The linkage push rod is connected with the main rack, the bottom plate supports on two sides of the main rack are respectively provided with an auxiliary gear, and two sides of the main rack are meshed with the two auxiliary gears. And a bevel gear is respectively arranged on the bottom plate bracket at the outer side of each pinion, and each pinion is meshed with the bevel gear at the outer side. Each bevel gear has a downwardly extending gear pawl. The tool can be applied to an assembly testing link, is used for quickly clamping parts and facilitating assembly, and can also be used on a platform type machining machine tool, such as a milling machine. Simultaneously, the power source of this frock can be for the pneumatic cylinder combination, provides the clamp force through hydraulic pressure to bevel gear and gear claw thickness can set up to be less than the thickness of the three-jaw chuck of corresponding type, and application scope is wider.
Description
Technical Field
The utility model belongs to the machining instrument field, in particular to three-jaw platform formula presss from both sides tight frock.
Background
The existing tool for clamping parts, such as a chuck, is thicker and has a limited application range, and the three-jaw chuck is only suitable for clamping round workpieces, and when the workpieces are oval or irregular, clamping is difficult to complete.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a tight frock of three-jaw platform formula clamp can make things convenient for the work piece of clamping irregular shape.
The technical scheme is as follows:
three-jaw platform formula presss from both sides tight frock, including the bottom plate support.
The technical key points are as follows:
the bottom plate bracket is in clearance fit with a linkage push rod in a penetrating way.
The linkage push rod is positioned at the inner end of the bottom plate bracket and connected to the upper end of the main rack.
The bottom plate supports on two sides of the main rack are respectively provided with an auxiliary gear, and the auxiliary gears are arranged on the bottom plate supports through auxiliary gear shafts. Two sides of the main rack are meshed with the two auxiliary gears.
The bottom plate bracket at the outer side of each pinion is respectively provided with a bevel gear, and the bevel gears are arranged on the bottom plate bracket through bevel gear shafts. Each pinion is engaged with the outer bevel gear.
Each bevel gear has a downwardly extending gear pawl.
The advantages are that:
the tool can be applied to an assembly testing link, is used for quickly clamping parts and facilitating assembly, and can also be used on a platform type machining machine tool, such as a milling machine. Simultaneously, the power source of this frock can be for the pneumatic cylinder combination, provides the clamp force through hydraulic pressure to bevel gear and gear claw thickness can set up to be less than the thickness of the three-jaw chuck of corresponding type, and application scope is wider.
Drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a perspective view of the present invention.
The device comprises a bottom plate bracket 1, a linkage push rod 2, a main rack 3, a workpiece 4, a secondary gear 5, a secondary gear shaft 6, a bevel gear 7, a bevel gear shaft 8 and a gear claw 9.
Detailed Description
Three-jaw platform formula clamping frock, including bottom plate support 1 (can fix on the lathe as required, as the dress anchor clamps usefulness).
The linkage push rod 2 is arranged in the bottom plate support 1 in a clearance fit mode in a penetrating mode, and the linkage push rod 2 can move up and down to drive the main rack 3 to move up and down.
The linkage push rod 2 is positioned at the inner end of the bottom plate bracket 1 and is fixedly connected with the upper end of the main rack 3.
The inner end boss of the linkage push rod 2 can be clamped in the groove at the upper end of the main rack 3 for fixing.
The bottom plate supports 1 on two sides of the main rack 3 are respectively provided with an auxiliary gear 5, and the auxiliary gears 5 are arranged on the bottom plate supports 1 through auxiliary gear shafts 6. The two sides of the main rack 3 are meshed with the two auxiliary gears 5.
A bevel gear 7 is respectively arranged on the bottom plate bracket 1 at the outer side of each pinion 5, and the bevel gear 7 is arranged on the bottom plate bracket 1 through a bevel gear shaft 8. Each pinion 5 meshes with an outer bevel gear 7.
Each bevel gear 7 has a downwardly extending gear claw 9. The two gear claws 9 can clamp the workpiece 4 by buckling.
The cylinder rod of the hydraulic cylinder is connected with the upper end of the linkage push rod 2, and the main rack 3 can be driven to move up and down by moving up and down.
The main rack 3 moves up and down and is simultaneously meshed to drive the auxiliary gears 5 on two sides to rotate, the bevel gear 7 is driven by the meshing of the auxiliary gears 5 to rotate to a certain angle, the two gear claws 9 and the lower end of the main rack 3 can clamp the workpiece 4, and the workpieces 4 in different shapes can be clamped by adjusting the angles and the shapes of the gear claws 9.
