Example

[0063] See attached Figure 1-5, an adjustment and limiting structure of a horizontal slide, the horizontal slide includes a slide frame 1 fixedly arranged on a base 3 and a slide body 2 slidably arranged on the slide frame 1, the slide frame 1 is arranged in a cube shape, and one end of the slide body 2 is connected to the excitation output table surface of the vibration table body through a screw.

[0064] The adjustment and limiting structure includes an adjustment structure 4 and a limiting structure 5 .

[0065] The adjustment structure 4 is positioned on the base 3 and applies thrust to the slide frame 1 in four directions, namely, front, rear, left, and right, to adjust the position of the slide frame 1. In this embodiment, the front and rear directions are the sliding directions of the slide body 2, and the left and right directions are two directions perpendicular to the sliding direction.

[0066] In this embodiment, the adjustment structure 4 includes two long push plates 411, four groups of wedge-shaped pressing blocks 412 and four groups of positioning rods 413. Among them:

[0067] The two long push plates 411 are symmetrically arranged on the left and right side walls of the slide frame 1, and the length direction thereof is the sliding direction of the slide body 2;

[0068] The surfaces of the two long push plates 411 are provided with a plurality of inclined surfaces 414, and each inclined surface 414 gradually tilts downward by about 45° from the inside to the outside of the slide frame 1, and is symmetrical left-right and front-back; specifically, the plurality of inclined surfaces 414 include two groups of first adjustment inclined surfaces 414 and two groups of second adjustment inclined surfaces 414; the two groups of first adjustment inclined surfaces 414 are respectively arranged on the surfaces of the two long push plates 411, and are symmetrical left-right, and each group of first adjustment inclined surfaces 414 is provided with two, and the two first adjustment inclined surfaces 414 are symmetrically arranged front-back; the two groups of second adjustment inclined surfaces 414 are respectively arranged on the surfaces of the two long push plates 411, and are symmetrical left-right, and each group of second adjustment inclined surfaces 414 is provided with two, and are symmetrical front-back; the adjustment inclined surfaces are arranged in pairs to ensure the horizontality of the position of the slide frame 1.

[0069] Each of the inclined surfaces 414 is provided with an adjustment through hole 415 , which vertically penetrates the lower surface of the long push plate 411 , and whose hole diameter is larger than the diameter of the positioning rod 413 ;

[0070] The wedge-shaped pressing block 412 is fitted in a one-to-one correspondence with the inclined surface 414;

[0071] The head of the positioning rod 413 abuts against the upper surface of the wedge-shaped pressing block 412 , and the tail thereof passes through the wedge-shaped pressing block 412 and the adjusting through hole 415 in sequence, and is positioned in the positioning hole 31 opened on the base 3 .

[0072] When the slide frame 1 and the slide body 2 are hoisted on the base 3, the adjustment through hole 415 needs to cover the positioning hole 31 on the base 3, so that the positioning rod 413 can be smoothly inserted into the positioning hole 31 for rotation, and the wedge-shaped pressing block 412 can be adjusted to move downward. For the convenience of operation, multiple angle steels can be fixed on the base 3 to preliminarily define the position of the slide frame 1, so that the adjustment through hole 415 covers the positioning hole 31 (not shown in the figure, but similar to the structure of the adjustment block 421 in Example 2).

[0073] When adjusting the position of the slide, the positioning rod 413 is inserted into the through hole on the wedge-shaped pressing block 412. The through hole may or may not be provided with a thread, so that the positioning rod 413 and the wedge-shaped pressing block 412 can be slidably matched or threadedly connected; when the positioning rod 413 and the wedge-shaped pressing block 412 are assembled, the tail end of the positioning rod 413 is inserted into the adjustment through hole 415 and the positioning hole 31 in turn, and the wedge-shaped pressing block 412 is fitted with the inclined surface 414. At this time, the positioning rod 413 is rotated using a tool such as a wrench, and the positioning rod 41 3 The head squeezes the wedge-shaped pressure block, and the wedge-shaped pressure block 412 gradually moves downward, continuously pushing the inclined surface 414 inward. At this time, the slide frame 1 is subjected to the horizontal component force and shifts in the horizontal direction, thereby fine-tuning the position of the slide frame 1; when the wedge-shaped pressure block 412 in the first adjustment inclined surface 414 is adjusted, the left-right direction position of the slide frame 1 can be adjusted, and when the wedge-shaped pressure block 412 in the second adjustment inclined surface 414 is adjusted, the front-back direction position of the slide frame 1 can be adjusted.

[0074] When the slide frame 1 is adjusted into position, the adjustment structure 4 is fixed to the base 3 through the limiting structure 5 to limit the slide frame 1. In this embodiment, the positioning rod 413 is a positioning screw, the positioning hole 31 is a positioning threaded hole, the positioning screw and the positioning threaded hole are threadedly matched, and the limiting structure 5 includes the positioning screw and the positioning threaded hole. When the positioning rod 413 adopts a positioning screw and the positioning hole 31 adopts a positioning threaded hole, then in the above adjustment step, when the positioning rod 413 is rotated, the positioning rod 413 will be threadedly matched with the positioning hole 31, and after the positioning rod 413 gradually moves down to fine-tune the position of the slide frame 1, the positioning rod 413 and the wedge-shaped pressure block 412 will be fixed on the base 3, thereby realizing the position limitation of the slide frame 1.

[0075] In order to further improve the stability of the slide frame 1, the limiting structure 5 also includes a limiting screw 511. A plurality of long holes are penetrated on the long push plate 411. A limiting screw hole 32 is formed on the base 3 corresponding to the long hole. The limiting screw 511 penetrates the long hole and is threadedly engaged with the limiting screw hole 32. A gasket 512 can also be sleeved under the head of the limiting screw 511. When the position of the slide frame 1 is adjusted into place, the combination of the limiting screw 511 and the gasket 512 can improve the stability of the slide frame 1, and the position of the slide frame 1 is limited by the wedge-shaped pressure block 412. Example

[0076] This embodiment is basically the same as Embodiment 1, except that:

[0077] See attached Figure 6-9 , the adjustment structure 4 includes four groups of adjustment blocks 421 and four groups of headless screws 422 arranged at the four corners of the slide frame 1;

[0078] Each group of adjustment blocks 421 is respectively distributed at right angles and positioned on the base 3. In this embodiment, the adjustment blocks 421 are detachably positioned on the base 3 by fixing screws 423; the outer right angles of the four corners of the slide frame 1 correspond to the inner right angles of the four groups of adjustment blocks 421 respectively;

[0079] The headless screw 422 corresponds to the adjustment block 421 one by one. The headless screw 422 is threadedly connected to the adjustment block 421 , and the tail end thereof is perpendicularly pressed against the outer right-angled side of the slide frame 1 .

[0080] The limiting structure 5 includes a locking nut 521 connected to the head end of each headless screw 422 , and the locking nut 521 is correspondingly fitted with the outer side wall of the adjustment block 421 .

[0081] In this embodiment, when the slide frame 1 and the slide body 2 are hoisted on the base 3, the slide frame 1 needs to be placed in the space surrounded by the inner sides of the four sets of adjustment blocks 421. At this time, the position of the slide frame 1 has a slight error and needs to be adjusted with a headless screw 422:

[0082] Use a wrench or other tool to rotate the headless screw 422, and the headless screw 422 and the adjustment block 421 thread cooperate, so as to continuously push forward the slide frame 1 on the inner side. When one end of the headless screw 422 squeezes the slide frame 1, the slide frame 1 can be pushed to move and the position can be fine-tuned. After the adjustment, install the locking nut 521. When the locking nut 521 abuts against the outer wall of the adjustment block 421, the locking of the headless screw 422 is completed, and the slide frame 1 is stably limited.

[0083] In the above two embodiments, whether the adjustment is made by the wedge-shaped pressure block 412 or the headless screw 422, it will not cause damage to the appearance of the slide frame 1, nor will it damage the internal structure of the slide to affect the performance of the slide, and it is also more labor-saving when adjusting.

[0084] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
