DETAILED DESCRIPTION

[0019] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a building measurement instrument correction device of the utility model in conjunction with the accompanying drawings.

[0020] See also Figure 1-Figure 4 The present embodiment provides a correction device for a building surveying instrument, comprising: a workbench 1, a spacing adjustment component and a reversing transmission component. A correction mechanism is arranged above the workbench 1, and the correction mechanism is used to correct bent parts; the spacing adjustment component is rotatably mounted on the workbench 1, and can adjust the spacing of the correction mechanism accordingly according to the different thicknesses of the parts; the reversing transmission component is mounted inside the workbench 1 and is transmission-connected to the correction mechanism, and is used to realize the synchronous rotation cooperation of the correction mechanism.

[0021] Compared with the prior art, by providing a correction mechanism and a spacing adjustment component, parts with different thicknesses can be corrected, which can effectively improve the applicable scope of the correction mechanism and further perform correction on different parts.

[0022] In one embodiment, the correction mechanism includes two parallel mounting frames 4, which are slidably connected to the rectangular grooves 7 provided on the workbench 1, and the mounting frames 4 are rotatably connected to the vertically provided mounting shafts 5, and the top of the mounting shafts 5 located outside the mounting frames 4 is fixedly connected to the rollers 6, and one end of the mounting shafts 5 located inside the mounting frames 4 is fixedly connected to the transmission wheels 14, and the adjacent transmission wheels 14 are connected through the transmission member 15. The transmission member 15 can be a belt or a chain.

[0023] In one embodiment, the reversing transmission assembly includes a drive shaft 10 and a mounting sleeve 12. The drive shaft 10 is rotatably connected to the workbench 1, and the mounting sleeve 12 is rotatably connected to the mounting frame 4. The mounting sleeve 12 and the drive shaft 10 are axially slidably matched. One end of the mounting sleeve 12 located inside the mounting frame 4 is fixedly connected to a worm 13. The mounting shaft 5 closest to the mounting sleeve 12 is fixedly connected to a worm wheel 19. The worm 13 and the worm wheel 19 are transmission-connected.

[0024] One end of the drive shaft 10 located inside the workbench 1 is fixedly connected to the transmission gear 16. The workbench 1 is rotatably connected to a vertically arranged transmission shaft 17 between two mounting frames. A reversing gear 18 is fixedly connected to the end of the transmission shaft 17. The reversing gear 18 is meshed with the two transmission gears 16 for transmission. A second motor 11 is fixedly installed at one end outside the workbench 1, and the second motor 11 is transmission-connected to one of the drive shafts 10.

[0025] In one embodiment, a control panel 3 is fixedly mounted on one end of the outside of the workbench 1 , and an output end of the control panel 3 is electrically connected to an input end of the second motor 11 .

[0026] When it is necessary to correct the parts of the building measurement instrument, the parts to be corrected are placed between the rollers 6 on both sides from one end of the workbench 1, and the second motor 11 is started by controlling the control panel 3. The second motor 11 then drives one of the drive shafts 10 to rotate, and the drive shaft 10 then drives the installation sleeve 12 in the middle of the installation frame 4 to rotate, and the installation sleeve 12 then drives the worm 13 to rotate. Due to the transmission connection between the worm 13 and the worm wheel 19, one of the installation shafts 5 can be further driven to rotate, and the installation shaft 5 then drives the transmission wheel 14 to rotate. Since the two adjacent transmission wheels 14 are connected through the transmission member 15, multiple installation shafts 5 can be further driven. The mounting shaft 5 rotates at the same time, and the mounting shaft 5 then drives the roller 6 to rotate, and as one of the driving shafts 10 rotates, the driving shaft 10 can drive the transmission gear 16 located at one end of the workbench 1 to rotate, and due to the meshing transmission between the transmission gear 16 and the reversing gear 18, the transmission of the reversing gear 18 can drive the driving shaft 10 at the other end to rotate in the opposite direction, and the driving shaft 10 then drives the middle mounting sleeve 12 and the worm 13 to rotate, through the transmission connection between the worm wheel 19 and the worm 13, and the transmission cooperation between the multiple transmission wheels 14, the roller 6 at the other end can be rotated in the opposite direction, and finally the correction of the parts is completed.

[0027] In one embodiment, the spacing adjustment assembly includes a forward and reverse screw rod 8, which is rotatably connected to the workbench 1 and whose forward and reverse threads are respectively matched with the threads of the two mounting frames 4. One end of the outside of the workbench 1 is fixedly connected to the first motor 9, and the first motor 9 is transmission-connected to the forward and reverse screw rod 8.

[0028] In one embodiment, a control panel 3 is fixedly mounted on one end of the outside of the workbench 1 , and an output end of the control panel 3 is electrically connected to an input end of the first motor 9 .

[0029] When it is necessary to correct parts of different thicknesses, the first motor 9 is started by controlling the control panel 3, and the first motor 9 then drives the forward and reverse screw rods 8 to rotate. Due to the threaded fit between the mounting frame 4 and the forward and reverse screw rods 8, the mounting frames 4 at both ends can be moved in different directions along the axis of the forward and reverse screw rods 8 through the rotation of the forward and reverse screw rods 8, and the sliding fit between the mounting frame 4 and the rectangular groove 7 can adjust the distance between the rollers 6 at both ends, so that the parts can be corrected according to the different thicknesses of the parts.
