DETAILED DESCRIPTION
[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0020] The embodiment of the present utility model: Figure 1-Figure 3 As shown, a hob adjustment device includes a base plate 1, two side plates 2 are fixedly provided on the base plate 1, support rollers 3 are installed on the two side plates 2, and a support roller height adjustment assembly is also provided on the base plate 1. An upper horizontal rod assembly is installed on the top of the two side plates 2, a dial indicator support assembly is installed on the upper horizontal rod assembly, and a dial indicator 63 is installed on the dial indicator support assembly.
[0021] The bottom plate 1 is a whole piece of stainless steel plate, which is used to support the entire device and the hob 4. The two side plates 2 are made of stainless steel. The sizes of the two side plates 2 are exactly the same. Side plate inner holes 21 are opened on both side plates 2. The height and size of the side plate inner holes 21 on the two side plates 2 are also exactly the same. The side plate inner holes 21 are long strip holes. The width of the side plate inner holes 21 is equal to the diameter of the support roller 3. The side plate inner holes 21 extend in the vertical direction. Therefore, the support roller 3 can only move in the vertical direction after being installed in the side plate inner holes 21.
[0022] The support roller 3 is preferably an iron round roller. The support roller 3 is used to install the hob 4. The hob 4 is the existing technology. The hob 4 has a hob inner hole 42. The diameter of the support roller 3 is equal to the diameter of the hob inner hole 42. Eight blades 41 are installed on the hob 4. The blades 41 are arranged at equal intervals on the circumference of the hob 4. The hob 4 can rotate on the support roller 3. By rotating the hob 4, different blades 41 can be adjusted to a vertical upward position for easy adjustment.
[0023] Furthermore, the support roller height adjustment assembly includes a fixed support rod 72 and a movable support rod 71. There are two movable support rods 71 and two fixed support rods 72. The lower ends of the two fixed support rods 72 are fixedly connected to the base plate 1. The upper ends of the two fixed support rods 72 are provided with bolt assemblies 73. An adjustment long hole is opened on the movable support rod 71. The movable support rod 71 is installed on the fixed support rod 72 through the cooperation of the adjustment long hole and the bolt assembly 73.
[0024] The two fixed support rods 72 are perpendicular to the bottom plate 1. The two fixed support rods 72 have the same size and the bolt assemblies 73 at their upper ends have the same height. The two movable support rods 71 are used to support the support roller 3 and adjust the height of the two ends of the support roller 3 so that the support roller 3 is in a horizontal state.
[0025] The sizes of the two movable support rods 71 are also exactly the same. When the height of the movable support rod 71 needs to be adjusted, the bolt assembly 73 is loosened, and the bolt assembly 73 is tightened after adjustment.
[0026] Preferably, a rubber pad 75 is fixed to the top of the movable support rod 71. The rubber pad 75 can protect the support roller 3. It prevents the support roller 3 from being damaged by direct friction with the top of the movable support rod 71.
[0027] Only by ensuring that the movable support rod 71 is in a vertical state after adjustment can the top heights of the two movable support rods 71 be consistent. Therefore, the support roller height adjustment assembly also includes a lower horizontal rod 7, and the two ends of the lower horizontal rod 7 are fixedly connected to the two fixed support rods 72 through lower horizontal rod screws 74.
[0028] The length of the lower horizontal rod 7 is greater than the distance between the two fixed support rods 72. When the lower end of the movable support rod 71 contacts the lower horizontal rod 7, it is in a vertical state. Therefore, after adjusting the height of the movable support rod 71, it is necessary to observe whether its lower part contacts the lower horizontal rod 7. If it contacts, it means that the movable support rod 71 is in a vertical state, and you can tighten the bolt assembly 73.
[0029] Furthermore, the upper horizontal rod assembly includes an upper horizontal rod 5 and an upper vertical rod 52. There are two upper vertical rods 52. The two upper vertical rods 52 are respectively fixed on the top of the two side panels 2. The two ends of the horizontal rod 5 are respectively connected to the two upper vertical rods 52 through the upper horizontal rod screws 51.
[0030] The two upper vertical rods 52 are of the same size. After being fixed to the two side panels 2, the tops of the two upper vertical rods 52 are at the same height. Both upper vertical rods 52 are provided with a plurality of height adjustment holes. In this embodiment, each upper vertical rod 52 has six height adjustment holes. The height adjustment holes are threaded holes. A through hole is provided at each end of the horizontal rod 5. Horizontal rod screws 51 pass through the through holes in the horizontal rod 5 and are threadedly connected to the height adjustment holes.
[0031] The dial indicator support assembly includes a dial rod 6 and a dial rod fixing block 62. The dial rod 6 is arranged horizontally. The dial rod fixing block 62 is fixed to the upper end of one of the upper vertical rods 52. One end of the dial rod 6 is plug-connected to the dial rod fixing block 62. A dial rod fixing screw 61 is provided on the dial rod fixing block 62.
[0032] A through hole for installing the dial stem 6 is provided on the dial stem fixing block 62, and a threaded hole perpendicular to the through hole is also provided. The dial stem fixing screw 61 is threadedly connected to the threaded hole, that is, the dial stem fixing screw 61 is perpendicular to the dial stem 6. The back of the dial indicator 63 has a mounting seat 65, which is slidably connected to the dial stem 6, and a dial indicator screw 64 is provided on the mounting seat 65.
[0033] The dial indicator rod 6 is always in a horizontal position when it moves. The measuring rod on the dial indicator 63 needs to be in a vertical position to ensure the accuracy of the measurement. When the measuring rod on the dial indicator 63 contacts the horizontal rod 5, it indicates that the measuring rod is in a vertical position. Therefore, after adjusting the position of the dial indicator 63, it is necessary to check whether the measuring rod of the dial indicator 63 is in contact with the horizontal rod 5.
[0034] The working principle of the present utility model is as follows: when in use, first pass the support roller 3 through the inner hole 42 of the hob 4, then respectively install the two ends of the support roller 3 into the inner holes 21 of the side plates 2, and then loosen the bolt assemblies 73 on the two fixed support rods 72, and adjust the heights of the two movable support rods 71 respectively so that the two movable support rods 71 support the two ends of the support roller 3 respectively. It is necessary to adjust the top surfaces of the two movable support rods 71 to the same height, and then tighten the bolt assembly 73. When tightening the bolt assembly 73, it is necessary to ensure that the lower ends of the two movable support rods 71 are in contact with the lower horizontal rod 7. At this time, the hob 4 is in a horizontal state.
[0035] Loosen the upper horizontal rod screw 51 and adjust the upper horizontal rod 5 to a horizontal position and the appropriate height. Then tighten the upper horizontal rod screw 51 and rotate one of the blades 41 on the hob 4 to the top and to a vertical position. Then loosen the indicator rod fixing screw 61 and move the position of the dial indicator 63 to measure the height of the blade 41 in the middle of the hob 4 and at points A and B in the figure. Adjust the height of the ends of the blade 41 according to the degree of the dial indicator 63 until the heights at the ends A and B measured by the dial indicator 63 are consistent with the height in the middle, indicating that the blade 41 meets the requirements. Then rotate the hob 4 to adjust the next blade 41.
