Abstract
Description
Technical Field
[0001] This utility model belongs to the field of large equipment installation technology and relates to an adjustment structure for inclined shims. Background Technology
[0002] The main uses of wedge shims are: to adjust the level of various equipment, preventing vibration and tilting during operation, ensuring smooth machine operation, reducing wear, and guaranteeing equipment safety. Features include: simple, convenient, and quick use; most are manufactured according to user needs, with wedge shim drawings designed based on the actual equipment base requirements, and then fabricated according to the drawings. Applications of wedge shims include: metal processing machine tools, forging presses, textile machinery, printing machinery, food processing machines, rubber machinery, wire production machinery, cable machinery, packaging machinery, generators, and large and heavy equipment. The method of use involves first placing a flat shim on the prepared concrete foundation, then placing two wedge shims crosswise on top of the flat shim. Adjustment is achieved by tapping the two shims with a hammer, using the inclination of the wedge shims to raise or lower the equipment to achieve the desired level. However, this method has relatively low adjustment accuracy. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable structure for inclined shims, which can more accurately adjust the height of large equipment.
[0004] The purpose of this utility model is achieved through the following technical solution: an adjustment structure for a shim, comprising an x-axis adjustment mechanism, a y-axis adjustment mechanism, and a z-axis adjustment mechanism. The z-axis adjustment mechanism is a lifting mechanism for adjusting the vertical position of the shim, and its lower end is connected to the x-axis adjustment mechanism. The x-axis adjustment mechanism is a first sliding mechanism for adjusting the front-to-back position of the shim, and its upper end is connected to the y-axis adjustment mechanism. The y-axis adjustment mechanism is a second sliding mechanism for adjusting the left-to-right position of the shim, and it is connected to the shim. The y-axis adjustment mechanism is housed within an adjustment box, and its lower end is connected to the z-axis adjustment mechanism.
[0005] The above scheme allows for positional adjustment in three dimensions along the x, y, and z axes via an adjustment mechanism, enabling highly precise adjustment of the shims.
[0006] Preferably, the z-axis adjustment mechanism includes a base, with first guide grooves at each of the four corners of the top surface of the base. Guide posts are located within the first guide grooves, and the upper ends of the guide posts are connected to the bottom surface of the x-axis adjustment mechanism. Two mounting seats are located between the first guide grooves, at both ends of the base. An adjusting screw is rotatably connected between the mounting seats, and one end of the adjusting screw is connected to a turntable. The adjusting screw is a double-ended reciprocating screw, with first moving blocks fitted at both ends. Connecting rods are rotatably connected to the upper ends of the first moving blocks, and connecting blocks are rotatably connected to the upper ends of the connecting rods. The connecting blocks are connected to the bottom surface of the x-axis adjustment mechanism.
[0007] By rotating the adjusting screw, the first moving block moves on the adjusting screw, thereby changing the inclination of the connecting rod and causing the pad to move in the vertical direction, i.e., the z-axis direction, which is convenient for adjustment.
[0008] Preferably, the x-axis adjustment mechanism includes an adjustment plate with multiple second guide grooves. A guide block is located within each second guide groove and is connected to the bottom surface of the adjustment box. An adjustment groove is located in the middle of the adjustment plate, parallel to the second guide grooves. An adjustment stud is rotatably connected within the adjustment groove. The adjustment stud is a reciprocating stud, with a turntable connected to one end. A second moving block is fitted onto the adjustment stud and is connected to the bottom surface of the adjustment box.
[0009] By rotating the adjusting stud, the second moving block moves in the x-axis direction, which in turn causes the adjusting box to move along the x-axis, thus enabling the pad to move in the x-axis direction.
[0010] Preferably, the guide post has a T-shaped structure and is adapted to the second guide groove.
[0011] Through the above solution, the guide post allows the shim to move stably on a fixed trajectory. The irregular structure of the guide post further reduces the vibration range of the shim and improves the adjustment accuracy.
[0012] Preferably, the y-axis adjustment mechanism is disposed on the adjustment box. The y-axis adjustment mechanism includes two adjustment rods, each with a thread. The adjustment rods are disposed at both ends of the adjustment box. One end of each adjustment rod passes through the side wall of the adjustment box and is threadedly connected to a screw hole. The screw hole is disposed at the lower end of a shim. The upper end of the shim has a through groove extending to the top of the adjustment box. The through groove is disposed on the top surface of the adjustment box.
[0013] By rotating the adjusting rod to fit the screw hole, the shim can be moved along the y-axis. The adjusting screw is located at both ends of the shim and also serves to fix the shim.
[0014] Preferably, the lower end of the pad is provided with a limiting block, which is disposed at the upper and lower ends of the through groove and abuts against the through groove.
[0015] Through the above scheme, the setting of the limiting block allows the pad to move in the through groove along a relatively fixed trajectory, thereby improving the adjustment accuracy.
[0016] Preferably, the side wall of the adjustment box is provided with an observation window, which is located on one side of the adjustment rod.
[0017] The above-described solution allows for easy observation of the movement speed of the shims, adjustment of the adjustment speed, and improved adjustment efficiency.
[0018] The beneficial effects of this utility model are: this utility model can adjust the position of the shim on the x, y, and z axes to achieve precise adjustment, and the adjustment method is simple and easy to operate compared with the traditional adjustment method. Attached Figure Description

[0025] Example
[0026] like Figures 1-4 As shown, an adjustment structure for a shim includes an x-axis adjustment mechanism 2, a y-axis adjustment mechanism 3, and a z-axis adjustment mechanism 1. The z-axis adjustment mechanism 1 is a lifting mechanism for adjusting the vertical position of the shim 6. The z-axis adjustment mechanism 1 includes a base 101, with first guide grooves 102 at each of the four corners of the top surface of the base 101. Guide posts 104 are provided in the first guide grooves 102, and the upper ends of the guide posts 104 are connected to the bottom surface of the x-axis adjustment mechanism 2. Two mounting seats 103 are provided between the first guide grooves 102, and the mounting seats 103 are located at both ends of the base 101. An adjusting screw 105 is rotatably connected between the mounting bases 103. One end of the adjusting screw 105 is connected to a turntable, which is located on one side of the base 101. The adjusting screw 105 is a double-headed reciprocating screw. First moving blocks 106 are sleeved on both ends of the adjusting screw 105. The distance between the first moving blocks 106 moves closer or further away as the adjusting screw 105 rotates. A connecting rod 107 is rotatably connected to the upper end of each of the first moving blocks 106. A connecting block is rotatably connected to the upper end of each connecting rod 107. The connecting block is connected to the bottom surface of the x-axis adjusting mechanism 2.
[0027] The lower end of the z-axis adjustment mechanism 1 is connected to the x-axis adjustment mechanism 2. The x-axis adjustment is a first sliding mechanism for adjusting the front-rear position of the shim 6. The x-axis adjustment mechanism 2 includes an adjustment plate 201, an adjustment groove 203 horizontally arranged, an upper end of the adjustment groove 203 connected to the adjustment box, second guide grooves 7 at both ends of the adjustment plate 201, guide blocks 202 in the second guide grooves 7, and guide blocks 202 connected to the bottom surface of the adjustment box. An adjustment groove 203 is provided in the middle of the adjustment plate 201, the adjustment groove 203 is parallel to the second guide groove 7, an adjustment stud 204 is rotatably connected in the adjustment groove 203, the adjustment stud 204 is a reciprocating stud, a turntable is connected to one end of the adjustment stud 204, a second moving block 8 is sleeved on the adjustment stud 204, and the second moving block 8 is connected to the bottom surface of the adjustment box. The guide post 104 has a T-shaped structure and is adapted to the second guide groove 7.
[0028] The upper end of the x-axis adjustment mechanism 2 is connected to the y-axis adjustment mechanism 3; the y-axis adjustment mechanism 3 is a second sliding mechanism for adjusting the left and right position of the shim 6, and the y-axis adjustment mechanism is connected to the shim 6; the y-axis adjustment mechanism is located inside the adjustment box, and the lower end of the adjustment box is connected to the Z-circumference adjustment mechanism. The y-axis adjustment mechanism 3 is located on the adjustment box, and includes two adjustment rods 11. The adjustment rods 11 are threaded and are located on both sides of the adjustment box and on the same horizontal line. One end of the adjustment rod 11 passes through the side wall of the adjustment box and is threadedly connected to a screw hole 11. The screw hole 11 is located at the lower end of the shim 6, and the upper end of the shim 6 is provided with a through groove 9, extending to the top of the adjustment box; the through groove 9 is located on the top surface of the adjustment box. The lower end of the shim 6 is provided with a limiting block 10, which is located at the upper and lower ends of the through groove 9 and abuts against the through groove 9.
[0029] The side wall of the adjustment box is provided with an observation window 4, which is located on one side of the adjustment rod 11.
[0030] In practice, the shim 6 is placed in the designated position, and then the large equipment to be installed is placed on the shim 6. The position of the shim 6 is adjusted in the x, y, and z axes according to the requirements of the corresponding equipment. During z-axis adjustment, the turntable is rotated, causing the adjusting screw 105 to rotate, thereby changing the position of the first moving blocks 106, which in turn changes the tilt angle of the connecting rod 107, thus changing the height of the shim 6 to fit the corresponding equipment. During adjustment, if the adjustment becomes excessive, simply rotate the turntable in the opposite direction. Then, the position in the x-axis direction can be selectively adjusted. Similarly, rotating the turntable causes the adjusting stud 204 to rotate, causing the second moving block 8 to move continuously, thus changing the position of the shim 6 in the x-axis direction. Subsequently, the position of the shim 6 in the y-axis direction can also be selectively adjusted. As needed, the adjusting rods 11 at both ends of the shim 6 can be rotated continuously to adjust the position of the shim 6 in the y-axis direction. The shims 6 are usually used in pairs. The setting of the adjustment mechanism makes it easy to make precise multi-directional adjustments to the position and height of the shims 6. During the adjustment process, when approaching the set position, the movement speed of the shims 6 can be observed through the observation window 4, and the rotation force can be adjusted to prevent over-adjustment.
