Description

Technical Field

[0001] The utility model belongs to the technical field of hot rolling of strip steel, and in particular relates to a cushion block structure with adjustable height. Background Art

[0002] At present, large equipment in the rough rolling area of ​​hot rolling production lines generally use high-strength alloy pads. The required height is adjusted by stacking alloy pads of different thicknesses. In the process of stacking alloy pads, there are problems such as long operation time and high work intensity for the crane to lift the pads back and forth. There is also a deviation in the stacking height, so each time the alloy pads are stacked, a steel ruler must be used to measure repeatedly. At present, the height adjustment of the production line for some small equipment is basically the same as that of large equipment, and there is no special pad with adjustable height.

The utility model provides a height adjustment effect for the support rod by providing a rotating rod to drive the first meshing tooth transmission structure inside the inner groove to rotate. Utility Model Content

[0004] The purpose of the utility model is to provide a cushion block structure with adjustable height, and the technical solution thereof is as follows:

[0005] A height-adjustable cushion block structure is disposed between two mating surfaces and is used to adjust the distance between the two mating surfaces, and comprises a lower fixed block structure and an upper movable block structure;

[0006] The lower end fixed block structure comprises: a bottom plate fixedly arranged on the lower end profile surface and a cavity block and a slide rail member arranged side by side on the bottom plate;

[0007] A cavity 2 is provided in the cavity block, which is at an acute angle to the horizontal direction.

[0008] A screw is fixed in the cavity.

[0009] One end of the screw rod that matches the corresponding part of the cavity is processed into a cone shape, and the other end of the screw rod extends from the inside of the cavity to the outside of the cavity;

[0010] A slider which can move along the slide rail is arranged on the slide rail member, and the slider is connected to a moving block;

[0011] The moving block is machined to have a thread surface adapted to the thread of the screw;

[0012] The screw rod, the moving block and the slider form a thread pair, and the linear motion of the moving block and the slider is established by driving the screw rod to rotate.

[0013] Further,

[0014] One end of the screw extending from the inside of the cavity to the outside of the cavity is arranged in a smooth angular shape, and a driving handle is adapted to the end of the smooth angular shape.

[0015] Further,

[0016] The moving block is detachably arranged.

[0017] Further,

[0018] The moving blocks are arranged in a plurality of blocks with different heights.

[0019] Further,

[0020] The moving block is formed with a profile perpendicular to the horizontal plane, and a scale is arranged on the profile.

[0021] The utility model provides a height-adjustable cushion block structure, which is set based on the principle of screw drive. By setting the cavity in the cavity block in the structure to be at an acute angle to the horizontal direction, the rotary motion of the screw drive is converted into linear motion, and then converted into motion in the height direction through the existence of the angle, so as to achieve height adjustment. By setting a profile perpendicular to the horizontal plane on the moving block in the structure, and providing a scale on the profile, precise height adjustment can be achieved. By setting the moving block in the structure to be detachable, and placing multiple groups of different heights at the same time, adaptation to different height requirements can be established.

[0030] Below, a height-adjustable cushion block structure of the present invention is further described in detail according to the accompanying drawings and specific implementation methods of the specification.

[0031] like Figure 1 The height-adjustable pad structure shown can be arranged between two mating surfaces to adjust the distance between the two mating surfaces, and includes a lower fixed block structure and an upper movable block structure; the lower fixed block structure includes: a bottom plate fixed on the lower surface, and a cavity block 1 and a slide rail member arranged side by side on the bottom plate; a cavity 2 with an acute angle to the horizontal direction is opened in the cavity block 1, and a screw 3 is fixed in the cavity 2, and one end of the screw 3 that matches the corresponding part of the cavity is processed into a cone shape to establish positioning and limit the screw. The other end of the screw 3 extends from the inside of the cavity to the outside of the cavity 2; the end extending from the inside of the cavity to the outside of the cavity is arranged in a smooth angular shape, and a driving handle 5 adapted to the end of the smooth angular edge is used to drive the screw 3 to rotate by rotating the driving handle 5. A slider that can move along the slide rail is provided on the slide rail, and the slider is connected to a moving block 4; through the connection between the slider and the moving block 4, a constraint on the moving block in the direction of screw rotation is established, and a thread surface that matches the thread of the screw 3 is formed on the moving block 4; the screw 3, the moving block 4 and the slider constitute a thread pair, and since a constraint on the moving block in the direction of screw rotation is established by the slider, the linear motion of the moving block and the slider along the direction of the screw can be achieved by driving the screw to rotate, thereby achieving height adjustment, such as Figure 2 As shown. At the same time, by setting a profile perpendicular to the horizontal plane on the moving block 4 in the structure, and setting a scale on the profile, accurate height adjustment can be achieved. By setting the moving block 4 in the structure in a detachable manner and setting multiple groups of different heights, adaptation to different height requirements can be established.
