Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, and more specifically, to a shim. Background Technology

[0002] Shims are typically placed between the equipment base and the foundation. Their main purpose is to evenly distribute the weight and working load of the equipment to the foundation. They are widely used in various processing equipment and can adjust the level of the equipment to ensure that the elevation and levelness of the equipment meet the specified requirements.

[0031] Example:

[0032] Please see Figure 1-4 A type of pad includes a wedge 1, an upper slider 2 slidably connected to the top inclined surface of the wedge 1, a lower slider 16 slidably connected to the bottom inclined surface of the wedge 1, an adjusting screw 3 internally threaded onto the wedge 1, a guide post 4 rotatably connected to the circumferential surface of the adjusting screw 3, through holes 5 on both the upper slider 2 and the lower slider 16, and the upper and lower ends of the guide post 4 slidably connected to the two through holes 5 respectively, detachably connected to the two symmetrical ends of the wedge 1, and grooves 7 on both symmetrical ends of the upper slider 2 and the lower slider 16, with each limiting sheet metal part 6 slidably connected to the two grooves 7 on one side of the upper slider 2 and the lower slider 16, and two scale components 8 on the symmetrical ends of the wedge 1, the upper slider 2 and the lower slider 16, corresponding to the four grooves 7.

[0033] In this embodiment, the wedge 1 is slidably connected between the upper slider 2 and the lower slider 16. The guide post 4 is installed on the outer surface of the adjusting screw 3, and one end of the adjusting screw 3 is threaded into the wedge 1. The upper slider 2 and the lower slider 16 are slidably connected to the guide post 4 through two through holes 5 respectively. The upper slider 2 and the lower slider 16 are in contact with the inclined surfaces at the upper and lower ends of the wedge 1 respectively. Two limiting sheet metal parts 6 are fixed on the symmetrical sides of the wedge 1 respectively. Each limiting sheet metal part 6 is slidably connected to two sliding grooves 7 on one side of the upper slider 2 and the lower slider 16. The two limiting sheet metal parts 6, together with the four sliding grooves 7, restrict the upper slider 2 and the lower slider 16 from both sides, so that the upper slider 2 and the lower slider 16 can maintain a stable sliding connection with the wedge 1. Two grooves 7 on the same side as the lower slider 16 correspond to a scale component 8. The height of the shim can be confirmed from both sides through the two scale components 8. When the shim is in use, it is connected to the ground foundation through the lower slider 16 and the upper slider 2 is connected to the bottom of the equipment. When adjusting the height of the equipment, the wedge 1 slides between the upper slider 2 and the lower slider 16 through the inclined surface by rotating the adjusting screw 3. After the wedge 1 moves, the distance between the upper slider 2 and the lower slider 16 is adjusted, thereby adjusting the height of the equipment. The guide post 4 is slidably connected between the upper slider 2 and the lower slider 16 through two through holes 5, so that the movement of the upper slider 2 and the limiting sheet metal part 6 remains stable when adjusting the height, and the rotation of the adjusting screw 3 remains stable.

[0034] Specifically, each limiting sheet metal part 6 includes a connecting part 61 and two bending parts 62. The connecting part 61 is detachably connected to one side of the wedge 1. The two bending parts 62 are both provided on the connecting part 61, and the two bending parts 62 are slidably connected to the two slide grooves 7 on one side of the upper slider 2 and the lower slider 16, respectively.

[0035] In this embodiment, when the wedge 1 slides between the upper slider 2 and the lower slider 16, it will drive the two connecting parts 61 to move. Each connecting part 61 drives the two bent parts 62 to slide in the two sliding grooves 7 on the same side. The two limiting sheet metal parts 6 and the four sliding grooves 7 cooperate to restrict the upper slider 2 and the lower slider 16 on the wedge 1, so that the upper slider 2 and the lower slider 16 always maintain a stable sliding connection with the wedge 1, and prevent the upper slider 2 and the lower slider 16 from separating from the wedge 1.

[0036] Specifically, the connecting part 61 and the two bending parts 62 are integrally bent.

[0037] In this embodiment, the limiting sheet metal part 6 consists of a connecting part 61 and two bending parts 62, which are bent into shape by sheet metal processing.

[0038] Specifically, each scale component 8 includes two sets of scale marks 81 and two indicator marks 82. The two sets of scale marks 81 are respectively set on one side of the upper slider 2 and the lower slider 16, and the two indicator marks 82 are respectively opened on one side of the wedge 1, and the two indicator marks 82 correspond to the two sets of scale marks 81 respectively.

[0039] In this embodiment, when the wedge 1 slides between the upper slider 2 and the lower slider 16 to adjust the height of the device, two indicator marks 82 correspond to two sets of scale marks 81 respectively, which makes it convenient for the staff to accurately grasp the height adjustment of the device.

[0040] Specifically, positioning grooves 9 are provided on the upper and lower inclined surfaces of the wedge 1. Positioning protrusions 10 are fixedly connected to the inclined surfaces of the upper slider 2 and the lower slider 16 near the wedge 1, and the two positioning protrusions 10 are slidably connected in the two positioning grooves 9 respectively.

[0041] In this embodiment, the two positioning groove groups 9 are respectively matched with the two positioning protrusions 10, which can position the upper slider 2 and the lower slider 16 when they are assembled with the wedge 1. At the same time, they can restrict the upper slider 2 and the lower slider 16 on the wedge 1, so that the sliding connection between the wedge 1, the upper slider 2 and the lower slider 16 can be further stabilized.

[0042] Specifically, the circumferential surface of the adjusting screw 3 is threaded with a nut 11, and the nut 11 corresponds to the guide post 4.

[0043] In this embodiment, the nut 11 restricts the guide post 4, so that the guide post 4 can be stably installed on the adjusting screw 3.

[0044] Specifically, two washers 12 are fitted on the circumferential surface of the adjusting screw 3, with one washer 12 located between one side of the guide post 4 and the head of the adjusting screw 3, and the other washer 12 located between the other side of the guide post 4 and the nut 11.

[0045] In this embodiment, two gaskets 12 are arranged on the symmetrical sides of the guide post 4, corresponding to the heads of the nut 11 and the adjusting screw 3 respectively, which can improve the stability of the guide post 4 between the heads of the nut 11 and the adjusting screw 3.

[0046] Specifically, screw sets 13 are threaded to both symmetrical ends of the wedge 1, and the two screw sets 13 pass through the two connecting parts 61 respectively.

[0047] In this embodiment, two sets of screws 13 are used to fix the two connecting parts 61, so that the two connecting parts 61 are stable on the symmetrical two sides of the wedge 1.

[0048] Specifically, the top of the upper slider 2 is provided with an upper connecting hole 14, and the bottom of the lower slider 16 is provided with a lower connecting hole 15.

[0049] In this embodiment, the upper slider 2 is connected to the bottom of the equipment via the upper connecting hole 14 and bolts, and the lower slider 16 is connected to the ground foundation via the lower connecting hole 15 and bolts.

[0050] Working principle: The top of the upper slider 2 is connected to the bottom of the equipment, and the lower slider 16 is connected to the ground foundation. When adjusting the height of the equipment, the adjusting screw 3 inside the guide column 4 is rotated, causing the wedge 1 to slide stably between the upper slider 2 and the lower slider 16 through the inclined surface. The wedge 1 is slidably connected to the guide column 4 through two through holes 5. During the sliding process of the wedge 1, the upper slider 2 will rise and fall smoothly above the lower slider 16, thereby realizing the adjustment of the equipment height. During the sliding process of the wedge 1, it will drive the two connecting parts 61 to move. Each connecting part 61 drives the two bending parts 62 to slide in the two slide grooves 7 on the same side. The two limiting sheet metal parts 6 cooperate with the four slide grooves 7 to restrict the wedge 1 on both sides during the sliding process, ensuring the stability of the wedge 1 sliding between the upper slider 2 and the lower slider 16. At the same time, during the sliding process of the wedge 1 causing the upper slider 2 to rise and fall, the indicator 82 will correspond to the scale 81, which makes it convenient for the staff to accurately grasp the height of the equipment adjustment.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
