Abstract
The utility model discloses a pressing device capable of limiting horizontal movement. The pressing device is characterized in that a casting beam is arranged in a working platform; a T-shaped nut is fixedly arranged at the lower end of a through hole of the casting beam; the upper end of the through hole of the casting beam is provided with a pressing plate; an axial hole of the pressing plate and the T-shaped nut is connected with a double-head bolt; and the lower end of the double-head bolt is in threaded connection with the T-shaped nut, and the upper end of the double-head bolt is provided with a pressing nut. The pressing device has the working process that after equipment to be pressed is stably placed on the working platform, the double-head bolt penetrates through the pressing plate and is screwed into the T-shaped nut in the casting beam, firstly the double-head bolt is screwed down, and then the nut is screwed down so as to enable the pressing plate to press the equipment. When the pressed equipment is subjected to horizontal force to generate a moving trend, the T-shaped pressing plate is sheared, and the horizontal movement of the pressed equipment can be blocked as long as the horizontal shearing strength of the T-shaped pressing plate meets the use requirement, so that the horizontal positioning action is performed.
Description
Technical field
The utility model belongs to mechanical equipment technical field, but is specifically related to the hold down gag that a kind of limit lateral moves.
Background technique
Some equipment make an experiment or working procedure in because a variety of causes can receive big transverse force, if do not overcome the suffered transverse force of equipment, tested device can produce horizontal sliding and causes test failure even have an accident at the trial.Existing hold down gag; Lean on the pretightening force of bolt and carry out fastening to equipment with the frictional force on ground; When receiving big transverse force; The frictional force on fastened equipment and ground is limited, and under bigger transverse force or the action of lateral load because of the vibration generation, fastened equipment has the transverse movement of generation trend.
Summary of the invention
The purpose of the utility model is; But the hold down gag that provides a kind of limit lateral to move; Solved in the existing technology owing to there is not effective fixing device, tested device produces horizontal sliding sometimes when test operation, influence operation or have the problem of potential safety hazard.
The technological scheme that the utility model adopted is; But the hold down gag that a kind of limit lateral moves is provided with the casting beam in worktable, and the through hole lower end of casting beam is installed with T type nut; The through hole upper end of casting beam is equipped with pressing plate; The axle center hole of pressing plate and T type nut is connected with a stud bolt, and the lower end of stud bolt is connected with T type nut thread, and the upper end of stud bolt is equipped with gland nut.
The beneficial effect of the utility model is, can limit the degrees of freedom of equipment in Vertical direction and substantially horizontal, effectively realized two-way location and fixation to equipment; This apparatus structure is simple, and is solid and reliable, easy to process, is easy to promote.
Description of drawings
But the structural representation of the hold down gag that Fig. 1 moves for the utility model limit lateral;
Fig. 2 is the utility model T type pressure plate structure 1 (the both wings plate thickness is different);
Fig. 3 is the utility model T type pressure plate structure 2 (the both wings plate thickness is identical).
Among the figure, 1. stud bolt, 2. pressing plate, 3.T type nut, 4. gland nut, 5. plain washer, 6. compacted equipment, 7. casting beam.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
With reference to Fig. 1; But the hold down gag that the utility model limit lateral moves is used for fixed equipment on platform, and its structure is: in worktable, be provided with casting beam 7, casting beam 7 structures are set to the casting beam of inverted T-shaped step through-hole; The through hole lower end of casting beam 7 is installed with T type nut 3; The through hole upper end of casting beam 7 is equipped with pressing plate 2, and pressing plate 2 is that face contacts with the interface of T type nut 3, and pressing plate 2 is connected with a stud bolt 1 with the axle center hole of T type nut 3; The lower end of stud bolt 1 is threaded with T type nut 3; The upper end of stud bolt 1 is equipped with gland nut 4, and gland nut 4 is lined with plain washer 5 between the two with pressing plate 2, and the wing plates on two sides lower surface and the worktable of pressing plate 2 have spacing.Be used to install compacted equipment 6 between one side wing lower surface of pressing plate 2 and the worktable.
T type nut 3 is to be threaded with stud bolt 1, or is set to integral structure.
Like Fig. 2, Fig. 3, pressing plate 2 is T type cross section, and pressing plate 2 through hole wing plates on two sides thickness confirm that according to actual needs the lower surface that can be set to wing plate is not on a plane or on a plane.
The working procedure of the utility model device is, compacted equipment 6 after worktable is placed steadily, is passed pressing plate 2 with stud bolt 1 and is screwed into the T type nut 3 in the casting beam 7, tightens stud bolt 1 earlier, and fastening nut 4 again, make pressing plate 2 compression apparatus.When compacted equipment 6 receives transverse force, when producing movement tendency, will shear T type pressing plate 2, as long as the lateral shear intensity of T type pressing plate 2 satisfies usage requirement, can stop compacted equipment 6 transverse movements, play the located lateral effect.
The utility model is the T type structural design through pressing plate 2, in compression apparatus, can inject in the casting beam 7, makes the transverse force of being born pass to platform (concrete foundation) through casting beam 7.Casting beam 7 is imbedded the enough usefulness of intensity to be mixed in the platform of ability soil cast; T type pressing plate inserts in the casting beam, and is placed on the front end of equipment transverse movement trend, through fastening piece equipment is pressed on the platform; In test or working procedure; When equipment received transverse force generation transverse movement trend, suffered transverse force passed to T type pressing plate 2 and through casting beam 7, is absorbed by (concrete foundation) platform; Thereby prevent compacted equipment vertical jitter and laterally move, realize the two-way fixing and location of equipment.
