Abstract
The utility model relates to the technical field of foot-pad bolts, and discloses a foot-pad bolt for balance adjustment of DNS equipment. The foot-pad bolt comprises a screw, a bolt head arranged at one end of the screw and a nut sleeving the screw, and a limiting mechanism limiting the nut to move along the length direction of the screw is further arranged on the screw. By the aid of the limiting mechanism, when the DNS equipment is mounted, nuts of multiple foot-pad bolts can be ensured to be equal in height, mounting precision is improved, and deviation of mounting is reduced.
Description
Technical field
The utility model relates to feet bolt technical field, more particularly, and particularly a kind of feet bolt regulating for DNS balance of plant.
Background technique
Carrying out DNS equipment, (DNS equipment is the rotary coating system that is applicable to 6 inches and 8 inches semiconductor crystal wafers of the DAINIPPON SCREEN of Dainippon Screen Manufacturing Co company exploitation.) while installing, need to ensure the balance of equipment, traditional method is: one, first the screw rod with feet bolt is screwed in to equipment, re-use the assistant tools such as tape measure the nut of each feet bolt is adjusted to sustained height; Two, first the nut of each stone bolt is threaded to sustained height, then screw rod is screwed in to equipment.First method, due to the limited space of device bottom, is not easy to carry out highly measure accurately and regulate, and accuracy error is larger; And second method can drive nut motion in the time of rotary screw, cause the height tolerance between each stone bolt, often use again the assistant tools such as tape measure repeatedly to adjust.Therefore, be necessary to design a kind of feet bolt of new structure.
Model utility content
The purpose of this utility model is to provide the feet bolt regulating for DNS balance of plant that a kind of precision is high, deviation is little.
In order to solve problem set forth above, the technical solution adopted in the utility model is: a kind of feet bolt regulating for DNS balance of plant, comprise screw rod, be located at the bolt head of screw rod one end, and be sheathed on the nut on screw rod, on described screw rod, be also provided with the position-limit mechanism that the described nut of restriction moves along spiro rod length direction.
According to a preferred embodiment of the present utility model: described position-limit mechanism comprises multiple pin holes of being located in spiro rod length direction, and the positioning dowel matching with multiple pin holes.
According to a preferred embodiment of the present utility model: described position-limit mechanism comprises multiple ring-type draw-in grooves of being located in spiro rod length direction, and the ring-type fixture block matching with multiple ring-type draw-in grooves.
According to a preferred embodiment of the present utility model: the head diameter of described positioning dowel is greater than the diameter of pin hole.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts position-limit mechanism, can ensure DNS equipment when mounted, ensures that the height of nut of multiple feet bolts is consistent, have improved installation precision and have reduced the deviation of installing.

Fig. 2 is the feet bolt embodiment's two who regulates for DNS balance of plant of the present utility model structural representation.
Description of reference numerals: 1, bolt head, 2, screw rod, 3, nut, 4, pin hole, 5, positioning dowel, 6, ring-type draw-in groove, 7, ring-type fixture block.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Embodiment one:
Consult shown in Fig. 1, the present embodiment provides a kind of feet bolt regulating for DNS balance of plant, comprises screw rod 2, is located at the bolt head 1 of screw rod 2 one end, and be sheathed on the nut 3 on screw rod 2, on described screw rod 2, be also provided with the position-limit mechanism that the described nut 3 of restriction moves along screw rod 2 length directions.
In the present embodiment, position-limit mechanism comprises multiple pin holes 4 of being located on screw rod 2 length directions, and the positioning dowel 5 matching with multiple pin holes 4.
As preferably, on above-mentioned screw rod 2, there is screw thread, nut 3 is outer-hexagonal with bolt head 1.
As preferably, the present embodiment is distributed with 4 pin holes 4 on screw rod 2, and diameter is 2mm, can be used for stoping nut 3 to bolt head 1 turn, to determine the distance of nut 3 and bolt head 1, can adjust as required the height of four pin holes 4.
As preferably, the head diameter of positioning dowel 5 need to be slightly larger than the diameter of pin hole 4, to guarantee that positioning dowel 5 is being fit into stable after pin hole 4.
The installation method of the feet bolt of the present embodiment is as follows: first determine that feet height h(is generally slightly larger than the height of device bottom wheel), next determines that (the distance > of nut 3 and bolt head 1 h) for the position of the pin hole 4 under this height, then the nut of each feet bolt 3 is threaded to corresponding pin hole more than 4 away from bolt head 1, and plug positioning dowel 5, again nut 3 is rotated gently to positioning dowel 5 directions, after nut 3 is touched positioning dowel 5, stop the rotation, finally screw rod 2 is screwed in to the bottom of machine.
The present embodiment simple to operate, installation efficiency is high, has saved the process of repeated measurement and adjusting bolt height; Validity is installed simultaneously high, same pin hole 4 is identical with the distance of bolt head 1, and positioning dowel 5 is located back nut 3 and fixed with the distance of bolt head 1.
Embodiment two:
Consult shown in Fig. 2, other are identical with embodiment one for the present embodiment, and difference is: the position-limit mechanism that the present embodiment adopts comprises multiple ring-type draw-in grooves 6 of being located on screw rod 2 length directions, and the ring-type fixture block 7 matching with multiple ring-type draw-in grooves 6.In use, ring-type fixture block 7 need to be snapped in the ring-type draw-in groove 6 of relevant position, can ensure that nut 3 screws in the height of position consistent.
Above-described embodiment is preferably mode of execution of the utility model; but mode of execution of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
