DETAILED DESCRIPTION

[0026] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0029] like Figure 1-Figure 3 As shown, the utility model specifically relates to a handheld guide rail 110 coplanarity measuring device 200 for a lifting mechanism, comprising a handle 210 and a limit abutment block 220, wherein a detection component is provided between the handle 210 and the limit abutment block 220;

[0030] The detection assembly includes two fixed rods, a threaded support sleeve and a bidirectional adjustment screw 260. The two fixed rods are arranged in parallel and include an upper fixed rod 231 and a lower fixed rod 232. The threaded support sleeve includes an upper support sleeve 241 used in conjunction with the upper fixed rod 231 and a lower support sleeve 242 used in conjunction with the lower fixed rod 232.

[0031] The bidirectional adjustment screw 260 is a double-thread structure, one end of the bidirectional adjustment screw 260 is threadedly connected to the lower support sleeve 242, and the other end of the bidirectional adjustment screw 260 is threadedly connected to the upper support sleeve 241. The bidirectional adjustment screw 260 can synchronously drive the upper support sleeve 241 and the lower support sleeve 242 to move relative to the upper fixed rod 231 and the lower fixed rod 232, respectively, and move closer to or away from each other;

[0032] The detection assembly is placed inside the lifting mechanism through the handle 210 , and the lower support sleeve 242 and the upper support sleeve 241 are respectively located between the upper and lower guide rails 110 inside the lifting mechanism, and the coplanarity of the guide rails 110 is detected.

[0033] It should be noted that the lifting mechanism is a rigid chain 100, and a guide rail 110 is provided inside the rigid chain 100. The guide rail 110 facilitates the movement of the chain. If there is an abnormality in the internal guide rail 110, the rigid chain 100 will tilt during movement. Therefore, it is necessary to detect the coplanarity of the guide rail 110.

[0034] In this embodiment, during the assembly process of the rigid chain 100, the reducer, servo motor and chain are not assembled temporarily. The personnel use the handle 210 to place the measuring device 200 into the rigid chain 100 through the assembly entrance of the reducer and the servo motor, so that the measuring device 200 is located at the device to be tested. In the case of coaxiality, it naturally fits the guide rail 110 to complete the coplanarity detection of the guide rail 110.

[0035] When the measuring device 200 is placed inside the rigid chain 100, the limit abutment block 220 abuts against the inner wall inside the rigid chain 100, and the handle 210 is provided with a shape structure used in conjunction with the assembly entrance. The handle 210 and the limit abutment block 220 ensure that the test is completed in a coaxial state.

[0036] In addition, the upper support sleeve 241 and the lower support sleeve 242 are naturally fitted with the guide rail 110 to complete the detection of the guide rail 110 .

[0037] Furthermore, when the distance between the upper and lower guide rails 110 inside the rigid chain 100 is large, the relative position of the bidirectional adjustment screw 260 is rotated and the positions of the upper support sleeve 241 and the lower support sleeve 242 are synchronously adjusted through the bidirectional adjustment screw 260, so that the upper support sleeve 241 and the lower support sleeve 242 are moved away from each other to complete the coplanarity detection of the guide rail 110. Of course, the position of the rotating screw is adjusted before the test, and then directly placed inside the rigid chain 100 for testing.

[0038] The threaded support sleeve is provided to ensure the stability of the bidirectional adjustment screw 260 during the rotation process and the detection process.

[0039] The upper support sleeve 241 is slidably connected to the upper fixed rod 231, and the lower support sleeve 242 is slidably connected to the lower fixed rod 232. The upper support sleeve 241 is linearly moved relative to the upper fixed rod 231 and the lower support sleeve 242 is linearly moved relative to the lower fixed rod 232 through the two-way adjustment screw 260. The upper support sleeve 241 and the lower support sleeve 242 move synchronously, moving away from or approaching each other.

[0040] The upper fixing rod 231 and the lower fixing rod 232 are both slidably connected with a guide fixing sleeve 250 , and the guide fixing sleeve 250 is an integrated structure with the upper supporting sleeve 241 or the lower supporting sleeve 242 , respectively. A position sensor 251 is disposed in the guide fixing sleeve 250 .

[0041] The position sensor 251 and the bidirectional adjustment screw 260 cooperate with each other to further ensure the accuracy of the measurement.

[0042] The guide fixing sleeve 250 is a hollow structure, and the position sensor 251 is located at the upper end of the guide fixing sleeve 250, which facilitates the wiring of the position sensor 251 and avoids wire wear during the test process.

[0043] The handle 210 is provided with a through hole in the axial direction to facilitate the wiring of the position sensor 251 .

[0044] The position sensors 251 are provided in multiple groups, and the multiple groups of position sensors 251 are used in cooperation with the guide rails 110 respectively, so that the position sensors 251 and the guide rails 110 correspond one to one, thereby ensuring the test accuracy.

[0045] The bidirectional adjustment screws 260 are provided in multiple groups, and the multiple groups of bidirectional adjustment screws 260 and the guide rails 110 are used in cooperation with each other, so that the bidirectional adjustment screws 260 and the guide rails 110 correspond one to one, thereby ensuring the test accuracy.

[0046] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solution of the present invention rather than to limit it. The protection scope of the present invention is not limited thereto. Although the present invention is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with the technical field can still modify the technical solution recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the present invention, and should all be covered within the protection scope of the present invention.
