Description

Technical Field

[0001] The utility model belongs to the technical field of linear guide rails, and in particular relates to a levelness detector for producing ultra-high precision linear guide rails. Background Art

[0002] At present, linear guides can be divided into roller linear guides, cylindrical linear guides and roller linear guides. With the increasing application of linear guides, people's requirements for linear guides are also getting higher and higher. During the production and processing of linear guides, it is necessary to perform plane inspection on the guides to avoid the irregular surface of the guides affecting the movement of the slider, causing the slider to move unsmoothly.

[0003] In the existing levelness tester used in the production of ultra-high precision linear guides, during the test, since the tester is pushed on the linear guide for moving test, the device and the guide will tilt during the pushing process, causing the instrument to detect inaccurate data for the guide rail. In addition, when testing the guide rail, the tester can only test the guide rail once, which can easily cause slight deviations in the data, greatly affecting the usability of the tester.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0027] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0029] See also Figure 1-Figure 7 As shown, the utility model is a levelness detector for the production of ultra-high precision linear guide rails, comprising an instrument body 1, a multi-position movable component 2 is fixedly installed in the inner cavity of the instrument body 1, detectors 3 are fixedly installed at both ends of the multi-position movable component 2, rolling components 4 are rotatably installed at the four corners of the instrument body 1, lifting components 5 are fixedly installed at the four corners of the instrument body 1, a fitting component 6 is threadedly installed on the bottom of the lifting component 5, and a guide rail 7 is arranged between the rolling component 4 and the fitting component 6.

[0030] When in use, the instrument body 1 is first placed on the guide rail 7. At this time, the four rolling components 4 rotatably installed on the instrument body 1 are located at the top of the guide rail 7, and the fitting component 6 is located at the bottom of the guide rail 7. Then the operator rotates the lifting component 5 with a screwdriver to rotate it, and the lifting component 5 drives the threaded fitting component 6 to move in the direction of the guide rail 7, and the fitting component 6 can be completely fitted with the guide rail 7, so as to ensure that the instrument body 1 can be completely fitted with the guide rail 7, and avoid the instrument body 1 shaking when the operator pushes the instrument body 1 to move, which causes the problem of inaccurate detection data;

[0031] Then the operator pushes the instrument body 1 to move, and then the instrument body 1 drives the detector 3 on the multi-position moving component 2 to move, and then the detector 3 detects the horizontality of the guide rail 7. At the same time, the multi-position moving components 2 located in the inner cavity of the instrument body 1 move closer to or farther away from each other, so that the multi-position moving component 2 can drive the detector 3 fixed thereon to move back and forth during the movement process. In addition to pushing the instrument body 1 to drive the detector 3 to detect the movement of the guide rail 7 once, the moving component 2 can also drive the detector 3 to move back and forth to perform multiple movement detections on the guide rail 7, thereby avoiding the problem of slight deviation in the data caused by only detecting the track 7.

[0032] Thus, by pushing the instrument body 1 to drive the detector 3 to detect the movement of the guide rail 7 once, the multi-position moving component 2 can drive the detector 3 thereon to detect the back and forth movement of the guide rail 7 multiple times during the movement, thereby ensuring the accuracy of the detection of the guide rail 7 and preventing the problem of data deviation caused by the detector 3 only detecting the guide rail 7 once.

[0033] The operator can rotate the lifting assembly 5 by using a screwdriver, so that the fitting assembly 6 can be completely fitted with the guide rail 7, thereby ensuring that the instrument body 1 can be completely fitted with the guide rail 7, avoiding the problem of inaccurate detection data caused by the shaking of the instrument body 1 when the operator pushes the instrument body 1 to move.

[0034] In one embodiment, for the above-mentioned instrument body 1 , the instrument body 1 includes a housing 101 , a push handle 102 is fixedly mounted on the top of the housing 101 , and a display screen 103 is fixedly mounted on the top of the housing 101 .

[0035] The push handle 102 is used for the operator to better push the housing 101 to move, and the display screen 103 is used to display the data detected by the detector 3 to ensure that the operator can intuitively understand the data detected by the detector 3 .

[0036] In one embodiment, for the above-mentioned multi-position moving component 2, the multi-position moving component 2 includes a servo motor 201, a power shaft 202 is fixedly installed on the output end of the servo motor 201, a rotating disk 203 is fixedly installed on the other end of the power shaft 202, both ends of the rotating disk 203 are rotatably installed with a synchronous rotating rod 204, and the other end of the synchronous rotating rod 204 is rotatably installed with a moving block 205.

[0037] In one embodiment, for the detector 3 , the detector 3 is fixedly mounted at the bottom of the moving block 205 , and a sliding rod 206 is penetrated and slidably mounted inside the two moving blocks 205 , and the sliding rod 206 is fixedly mounted in the inner cavity of the housing 101 .

[0038] During the movement of the shell 101, the detector 3 will be driven to move to detect the guide rail 7. At the same time, the servo motor 201 will drive the power shaft 202 fixedly installed at the output end to rotate, and then the power shaft 202 will drive the fixedly installed rotating disk 203 to rotate, and then the rotating disk 203 will synchronously rotate the two synchronous rotating rods 204 rotatably installed thereon. Since the two moving blocks 205 are slidably installed on the sliding rod 206, the two synchronous rotating rods 204 will then respectively drive the moving blocks 205 rotatably installed thereon to move on the sliding rod 206, and then the two moving blocks 205 will respectively drive the detectors 3 fixedly installed thereon to move, so that the detector 3 can perform multiple movement detections on the guide rail 7 back and forth, thereby avoiding the problem of slight deviation in the data caused by only detecting the track 7.

[0039] In one embodiment, for the above-mentioned lifting component 5, the lifting component 5 includes a support frame 501, one end of the support frame 501 is fixedly installed on the outer shell 101, and a threaded rod 502 is rotatably installed inside the support frame 501, a sliding plate 503 is slidably installed and sleeved inside the support frame 501, and the threaded rod 502 is threadedly installed with the sliding plate 503.

[0040] The fitting assembly 6 includes a rotating shaft 601 , which is fixedly mounted on the sliding plate 503 . A roller 602 is fixedly mounted on the other end of the rotating shaft 601 , and the roller 602 abuts against the bottom of the inner cavity of the guide rail 7 .

[0041] When in use, first place the shell 101 on the guide rail 7. At this time, the four rolling assemblies 4 rotatably installed on the shell 101 are located at the top of the guide rail 7, and the four rollers 602 are located at the bottom of the guide rail 7. Then the operator rotates the threaded rod 502 by a screwdriver. Then the rotation of the threaded rod 502 will cause the sliding plate 503 threadedly installed thereon to move inside the sliding plate 503. Then the sliding plate 503 will drive the fixed rotating shaft 601 to move, and the rollers 602 rotatably installed on the rotating shaft 601 will move until the rollers 602 can completely fit the guide rail 7, so as to ensure that the shell 101 can completely fit the guide rail 7, and avoid the shell 101 shaking when the operator pushes the shell 101 to move, which will cause inaccurate detection data.
