Abstract
The invention discloses a rotatable clamp, which comprises a base plate and a loading disc positioned on the base plate. An axis which is positioned between the centers of the base plate and the loading disc is in rotatable connection with the base plate and the loading disc. Eighteen pin holes are annularly distributed on the base plate uniformly. Four screwed holes and two groups of pin holes (four pin holes in each group) are distributed on the loading disc; and three bearing pins are fixedly connected to the loading disc. The screwed holes are connected with bolts and pressing plates for pressing a workpiece, and the base plate and the loading disc are fixed by inserting one group of four pins in the pin holes. After being arranged on a machine tool, the rotatable clamp can increase a rotational degree of freedom for the machine tool which has only three mobile freedom degrees so as to change the triaxial machine tool into a four-axis machine tool in the simple and economic mode.
Description
Technical field
The present invention relates to the rotatable clamp in a kind of application machine processing.
Background technology
Machine tool can only be realized three moving in the prior art, when the needs workpiece rotates, just can only repeat the location is installed like this, so just repeats to have brought into alignment error, and the workpiece machining accuracy is reduced.
Summary of the invention
The purpose of this invention is to provide a kind of rotatable anchor clamps, can make three machine tools become four lathes.
The technical solution adopted in the present invention is: a kind of rotatable clamp, comprise the chassis, be positioned at the loading dish on the described chassis, the center that is positioned at described chassis and described loading dish has an axle and described chassis and described loading dish to be rotationally connected, annular is evenly equipped with 18 pin-and-holes on described chassis, on described loading dish, be distributed with four screwed holes and two groups every group four s' pin-and-hole, on described loading dish, be fixedly connected with three supporting nails.Described screwed hole is connected with pressing plate with screw and is used for workpiece pressing, and it is fixing that described chassis and described loading dish rely on one group of four pin to be inserted on the described pin-and-hole.
Owing to adopted above technical scheme to make the present invention have following advantage: after these anchor clamps are installed on the lathe, can make the lathe that has only three one-movement-freedom-degrees increase a rotational freedom, thereby three lathes are become four lathes with the mode of this simple economy.

The specific embodiment
Referring to accompanying drawing 1 to shown in the accompanying drawing 4, a kind of rotatable clamp, comprise chassis 1, be positioned at the loading dish 2 on the described chassis, the center that is positioned at described chassis 1 and described loading dish 2 has an axle 6 and described chassis 1 and described loading dish 2 to be rotationally connected, annular is evenly equipped with 18 pin-and-holes 4 on described chassis 1, on described loading dish 2, be distributed with four screwed holes 5 and two groups every group four s' pin-and-hole 4, on described loading dish 2, be fixedly connected with three supporting nails 3.Described screwed hole 5 is connected with pressing plate 8 with screw 7 and is used for workpiece pressing, and it is fixing that described chassis 1 and described loading dish 2 rely on one group four pins 9 to be inserted on the described pin-and-hole 4.After workpiece is by the supporting on the described loading dish 2 nail 3 and pressing plate 8 location, pull up pin 9, can rotate according to processing request between described chassis 1 and the described loading dish 2, turn to and plug pin behind the Working position and just can fix continuing and process.
After these anchor clamps are installed on the lathe, can make the lathe that has only three one-movement-freedom-degrees increase a rotational freedom, thereby three lathes are become four lathes with the mode of this simple economy.
