Abstract

The utility model discloses a following support used for vibration absorption. Three support legs of the following support are uniformly distributed in a rotation center, horizontally mounted on a large sliding table, and connectedly positioned through a supporting plate; three locking blocks with Houghs are respectively fixed on the supporting plate; an actuating travel sleeve passes through each locking block; an oil cylinder is fixed at the bottom end of the actuating travel sleeve; the head of a piston rod on the oil cylinder is connected with a push rod; the push rod is mounted in the actuating travel sleeve; a disc spring is mounted in an inner hole of the push rod; a mandrel for clamping workpieces is arranged on the upper surface of the disc spring; and an anti-rotation screw used for preventing the mandrel from rotating is further mounted at the outer part of the actuating travel sleeve. When the oil cylinder of the entire device is filled with oil, the push rod and the mandrel are driven to move together; the mandrel is tightly propped against parts, thereby achieving the effect of vibration absorption. The following support is composed of three groups of supports, thereby better serving the vibration absorption effect; the mandrel of the following support which is in contact with the workpieces is made of wear resistant materials, thereby better serving the wear-resistant function. Therefore, the following support has the advantages of simple structure and convenient assembly and disassembly, improves the operating efficiency and the processing quality and precision of the parts.

Description

A kind of support of following that is used for vibration damping

One, technical field

The utility model relates to the support of following that a kind of vibration damping uses.Specifically, be the support of following that when Milling Process, reduces vibration.

Two, background technology

In the oil drilling industry, need be during the processing drilling rod at its surperficial milling trisection helicla flute, because milling amount is big, drilling rod is long (9m ~ 13m), so can produce very big vibration in milling process, vibration can aggravate tool wear, even can break cutter, in addition, also influence the surface quality and the precision of part, finally cause processing parts efficient low, the processing cost height.Now the oscillation damping method that generally adopts just increases by one on the milling cutter opposite and follows support, the position of this support and workpiece be fix and do not adjust surplus, just do not have elasticity yet, can not reach the purpose of absorbing, so should the support meeting along with workpiece vibrates together; And what the push rod material that this support contacts with workpiece adopted is nylon, and the wearability of nylon is relatively poor, needs often to change; In addition, just some contact makes workpiece not steady more when milling between this support and the workpiece.In sum, this milling process that is supported on can't play damping effect, can not reach the effect of raising the efficiency and improving workpiece surface quality.

Three, summary of the invention

1, goal of the invention: the purpose of this utility model be provide at the problem that exists in the milling process a kind of simple in structure, mounting or dismounting are convenient, and the vibration damping with good actual use effect is followed support.

2, technical scheme: a kind of support of following that is used for vibration damping described in the utility model, it comprises push rod, push rod, nut, the rise cover, oil cylinder, the dish spring, latch segment, gripper shoe and supporting leg, three supporting legs are distributed in centre of gyration level and are installed on the big slide unit, connect the location by a gripper shoe between three supporting legs, three latch segments that have a Hough are separately fixed at the position of corresponding supporting leg on the gripper shoe, pass rise cover in each latch segment and fix by the screw on the latch segment Hough, rise puts to be equipped with and is used for the nut of adjustment stroke, oil cylinder is fixed on rise cover bottom, piston rod head on the oil cylinder is connected with push rod, push rod is installed in the rise cover and can moves back and forth along the rise cover, the dish spring is packed in the endoporus of push rod, is provided with the push rod of holding workpiece above the dish spring.The outside anti-turn screw that is used for preventing the push rod rotation that also is equipped with of rise cover.Package unit drives push rod and push rod and moves together when the oil cylinder oil-feed, and push rod holds out against part, thereby reaches effectiveness in vibration suppression.

3, beneficial effect: remarkable advantage of the present utility model is, it is made of three groups of supports, can better play effectiveness in vibration suppression, and the push rod that it contacts with workpiece is that high-abrasive material is made, and can better play wear-resisting effect.Simple in structure, install and remove conveniently, can increase work efficiency, improve part processing quality and precision.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to structural representation.

Five, the specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of support of following that is used for vibration damping mainly is made up of push rod 1, push rod 2, nut 3, rise cover 4, oil cylinder 5, dish spring 6, latch segment 7, anti-turn screw 8, gripper shoe 9, supporting leg 10, lock-screw 11.Three supporting legs 10 are distributed in centre of gyration level and are installed on the big slide unit, each is 120 degree at interval, connect the location with the generator whole rigidity by a gripper shoe 9 between three supporting legs 10, three latch segments 7 that have a Hough are separately fixed at the position of corresponding supporting leg 10 on the gripper shoe 9, pass rise cover 4 in each latch segment 7 and fix by the screw on latch segment 7 Houghs, be equipped with on the rise cover 4 and be used for the nut 3 of adjustment stroke, oil cylinder 5 is fixed on rise cover bottom, piston rod head on the oil cylinder 5 is connected with push rod 2, push rod 2 is installed in the rise cover and can moves back and forth along the rise cover, dish spring 6 is packed in the endoporus of push rod 2, is provided with the push rod 1 of holding workpiece above the dish spring 6.Rise overlaps 4 outsides the anti-turn screw 8 that is used for preventing the push rod rotation is housed.

Action specification:

Push rod 1 is installed in the endoporus of push rod 2 with dish spring 6, and anti-turn screw 8 screws in and prevents push rod 1 rotation in the push rod 2.And push rod 2 is contained in rise and overlaps in 4 bodies, and the piston rod head of oil cylinder 5 screws in push rod 2 bottoms, and is connected with rise cover 4 usefulness bolts.On the rise cover 4 nut 3 is housed and is used for adjusting its axial location, rise cover 4 inserts and has in the latch segment 7 of Hough, and with lock-screw 11 lockings, and latch segment 7 bottoms are fixed on the gripper shoe 9.Gripper shoe 9 and three supporting legs 10 are installed on the big slide unit.When oil cylinder 5 oil-feeds, piston promotes push rod 2 and moves to the workpiece direction, when reaching oil cylinder 5 ranges, unclamp lock-screw 11, with the clockwise turn nut 3 of hand, rise cover 4 drives oil cylinder 5 and moves upward, and push rod 1 is against on the workpiece, till one group of dish spring 6 axially has been compressed 5mm, be wrenched lock-screw 11 this moment.When the diameter of workpiece differ to the time, axial location that can be by adjusting rise cover 4 and change the push rod 1 that is fit to diameter of work and meet the demands, thus reach vibration damping and improve the effect of workpiece surface quality.
