Abstract

The utility model relates to the elastic support impact damper of the machine tool and the equipment, a base is connected with a lifting seat by screws, the centre is provided with through holes which are upward luxuriated into conical holes, hemisphere pads for supporting the machine tool is contacted with the conical hole walls of the lifting seat by the spherical surface, the center through hole is communicated with the center hole of the lifting seat, an expansion bolt and an anchor bolt are used to pass through holes, the upper ends of the bolts are connected with the footing of the machine tool, and the expansion head of the lower end or the foot margin extends out of the base and is fixed in the cement foundations. The impact damper having rigidity combined with elasticity is suitable for the machine tool with high gravity center, great vibration and eccentric cutting, having excellent stability and damping effect.

Description

Damper having rigidity combined with elasticity

The utility model is the vibration damper about machinery, and it is a kind of yielding support, belongs to engineering part.

I disclose a kind of board joint touch mechanical damper in 89205280 patents of having authorized, it is by base, parts such as elevating bracket and cushion are formed, contact and load-bearing with the bottom surface of machinery by the flat board in the shallow slot of elevating bracket top, this structure is specially adapted to not have the machinery use in footing hole, but also there is deficiency, this be because between flat board and the elevating bracket with plane contact, be difficult to fit fully, easily produce the space, and influence stability, secondly, in this structure and the prior art vibration damper of other structure still difficulty to satisfy some center of gravity too high, the damping requirement of the lathe that impact force is especially big.

It is good that the purpose of this utility model provides a kind of contact stabilization, can adapt to the vibration damper of the damping needs of center of gravity height, lathe that impact force is big.

The utility model vibration damper comprises base, support pads and elevating bracket, elevating bracket and base are to be threaded and rotatable lifting, the center of elevating bracket has through hole, the top of through hole upwards is extended to taper, support pads is the hemisphere pad, this ball pad contacts with above-mentioned taper hole wall with sphere, Transverse plane is the supporting surface of lathe on it, the center of ball pad has through hole, this hole communicates with the center hole of elevating bracket, runs through base with EXPANSION ANCHOR BOLTS or stone bolt, the center hole of elevating bracket and hemisphere pad, the footing hole of lathe is passed in the upper end of bolt, and locks with nut.During installation, the inflating end of bolt or ground foot stretch into ground and with cement casting.In order to adapt to the big lathe of lateral impact forces (dig as ox etc.), this vibration damper can be driven two positioning holes on base, insert with locating stud, and insert in the ground lower end of pin.

In sum, the utility model vibration damper adopts sphere to contact Automatic Levelling with the conical surface, increased stability, adopt stone bolt or EXPANSION ANCHOR BOLTS to run through connection, and make expansion-head or lower margin stretch into ground to fix, be adapted to the center of gravity height especially, vibrations lathe big, that eccentric cutting is arranged uses.

Below in conjunction with description of drawings embodiment of the present utility model.

Accompanying drawing is the structural representation of the utility model vibration damper.

As Fig. 1, the utility model vibration damper is by base 12, elevating bracket 6 and hemisphere pad 5 are formed, the base bottom is provided with cushion 9, the center has tapped hole, elevating bracket and base are to be threaded and lifting, base has horizontal screw, in the hole with fastening block 10 with to end a screw 11 further fixing and place restrictions on the axial positions of elevating bracket 6, elevating bracket has through hole, the top in hole expands to cone shape hole, the taper wall contacts with hemisphere pad 5, and the last Transverse plane of hemisphere pad is the supporting surface of lathe 4, and stone bolt 1 runs through base, elevating bracket, the hemisphere pad, its upper end penetrates the footing hole of lathe 4, with pad 3 and nut 2 lockings, the lower end lower margin of stone bolt 1 stretches in the hole of ground reservation, fixes with cement casting; Base 12 also has positioning hole, and Kong Zhongke inserts locating stud 8, with external force positioning dowel is gone into the concrete floor base and fixes.Elevating bracket 6 has horizontal driving hole 7, is used to insert spanner rotation and lifting seat.

Stone bolt that the utility model adopted and EXPANSION ANCHOR BOLTS are standard piece, buyable.

This vibration damper is when being used in the not too big lathe of shock momentum, and generally bolt replaces EXPANSION ANCHOR BOLTS, and ground needn't be stretched in its lower end.

Claims

1, firm bullet is in conjunction with vibration damper, comprise base support pad and elevating bracket, elevating bracket and base are to be threaded and rotatable lifting, the center that it is characterized in that elevating bracket 10 has through hole, and the top of through hole upwards is extended to taper, and support pads is a hemisphere pad 5, this ball pad contacts with above-mentioned taper hole wall with sphere, its center has through hole, and this hole communicates with the center hole of elevating bracket 10, runs through the center hole of base 12, elevating bracket 6 and hemisphere pad 5 with EXPANSION ANCHOR BOLTS or stone bolt 1.

2, the described vibration damper of claim 1 as mentioned above is characterized in that also having two positioning holes on the base, and is furnished with locating stud 8.
