For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0046] As described in the background, during the production and use of the linear guide rail, the parameters and sizes of the linear guide rail need to be sampled and detected, for example, whether the center height of the ball groove, the center distance of the ball groove and the inner distance of the groove are qualified, so as to ensure the normal use of the linear guide rail and avoid equipment failure. At present, non-contact guide rail profile measuring devices are usually used for detection, but the device is expensive, complex in structure and difficult to operate, resulting in increased cost and low detection efficiency.

[0047] Based on this, please refer to Figures 1-9 The embodiment of the utility model provides a linear guide rail gauge 100, which can effectively improve the above-mentioned technical problems, that is, the structure is simple, the operation is convenient, the linear guide rail 200 can be quickly sampled and detected, the detection efficiency is improved, and the cost is reduced. The linear guide rail gauge 100 will be described in detail below.

[0048] Please refer to Figure 1 , Figure 1 The structure diagram of the linear guide rail 200 provided in the embodiment, combined with Figure 1In the production and use process, the ball groove center height H, the ball groove center distance A and the ball groove inner distance B of the linear guide rail 200 need to be detected by using the gauge to determine whether the linear guide rail 200 is qualified.

[0049] Specifically, refer to Figures 2-5 , Figure 2 The first state structure diagram of the linear guide rail gauge 100 provided in the embodiment is shown in Figure 3 The first perspective structure diagram of the second state of the linear guide rail gauge 100 provided in the embodiment is shown in Figure 4 The partial structure diagram of the linear guide rail gauge 100 provided in the embodiment is shown in Figure 5 The second perspective structure diagram of the second state of the linear guide rail gauge 100 provided in the embodiment is shown in

[0050] Combined with Figures 1-5 , the linear guide rail gauge 100 includes a fixed seat 10, a movable seat 20, a first groove matching piece 30, a second groove matching piece 40 and a driving piece 50. The fixed seat 10 is provided with a mounting groove 11 for mounting the linear guide rail 200, and the side wall of the mounting groove 11 is provided with a first matching groove 12. The movable seat 20 is movably arranged on the fixed seat 10, and the side of the movable seat 20 close to the mounting groove 11 is provided with a second matching groove 21, the center height of the second matching groove 21 is the same as that of the first matching groove 12. The first groove matching piece 30 is arranged in the first matching groove 12, and the second groove matching piece 40 is arranged in the second matching groove 21. When the linear guide rail 200 is mounted in the mounting groove 11, the first groove matching piece 30 is used to match the first ball groove 201, and the second groove matching piece 40 is used to match the second ball groove 202. The driving piece 50 is arranged on the fixed seat 10 and is used to drive the movable seat 20 to move relative to the fixed seat 10.

[0051] That is, when detecting, first groove matching piece 30 and second groove matching piece 40 are arranged in first matching groove 12 and second matching groove 21 respectively, then linear guide rail 200 is installed in installation groove 11, movable seat 20 is driven by driving piece 50 to move towards installation groove 11, so that first groove matching piece 30 and second groove matching piece 40 respectively match first ball groove 201 and second ball groove 202 of linear guide rail 200, so that linear guide rail gauge 100 can match linear guide rail 200 to slide. Since the center height of second matching groove 21 is the same as the center height of first matching groove 12, that is, first ball groove 201 and second ball groove 202 are on the same horizontal line, the distance between linear guide rail 200 and the bottom wall of installation groove 11 can be measured by using different plug gauges, that is, whether the center height of ball groove meets the requirements can be determined; the size data between first groove matching piece 30 and second groove matching piece 40 can also be measured by using a vernier caliper, so that the center distance of ball groove and the inner distance of groove are obtained, then whether the relevant parameters are within the error range is compared, that is, whether linear guide rail 200 is qualified is determined.

[0052] It can be understood that the linear guide rail gauge 100 has simple structure and convenient operation, and can quickly carry out sampling inspection on the linear guide rail 200, without using relatively complex measuring instruments, thereby improving the detection efficiency and reducing the cost.

[0053] It should be noted that the first state mentioned in the above content can be understood as the state of linear guide rail gauge 100 when driving piece 50 does not drive movable seat 20 to move, and the second state can be understood as the state of linear guide rail gauge 100 after driving piece 50 drives movable seat 20 to move and matches linear guide rail 200.

[0054] As shown in Figure 5 When linear guide rail 200 is installed in installation groove 11 and matches the gauge, linear guide rail 200 has a certain distance T from the bottom wall of installation groove 11, which can be understood as the height to be detected whether it is qualified. At this time, two plug gauges can be used for detection, the sizes of the two plug gauges are T1 and T2 respectively, and T1 < T2, that is, the range between plug gauge T1 and plug gauge T2 is the error range of the center height of ball groove. If plug gauge T1 can be inserted into the gap between linear guide rail 200 and the bottom wall of installation groove 11, and T2 cannot be inserted into the gap, that is, T1 < T < T2, then it is determined that the center height H of the ball groove meets the requirements. If plug gauge T1 cannot be inserted into the gap, or plug gauge T2 can be inserted into the gap, then it is determined that the center height H of the ball groove does not meet the requirements.

[0055] Please continue to combine Figure 1The first ball groove 201 comprises a first groove 2011 and a second groove 2012 which are connected in communication, and the second ball groove 202 comprises a third groove 2021 and a fourth groove 2022 which are connected in communication. The first groove 2011 and the third groove 2021 are used for installing balls, that is, the center distance A of the ball grooves needs to be measured; the second groove 2012 and the fourth groove 2022 are used for storing lubricating oil or grease, that is, the inner distance B of the grooves needs to be measured.

[0056] It should be noted that, in the embodiment, the first groove fitting part 30 and the second groove fitting part 40 of two different structures are used to respectively measure the center distance A of the ball grooves and the inner distance B of the grooves. Specifically, Figure 2 、 Figure 3 and Figure 5 is a way of detecting the center distance of the ball grooves of the linear guide rail 200 by using the first groove fitting part 30 and the second groove fitting part 40 of the first kind; Figures 6-9 is a way of detecting the inner distance of the grooves of the linear guide rail 200 by using the first groove fitting part 30 and the second groove fitting part 40 of the second kind.

[0057] Please continue to refer to Figure 5 For detecting the center distance of the ball grooves, in the embodiment, the shapes of the first groove fitting part 30 and the second groove fitting part 40 are both cylindrical, the cylindrical first groove fitting part 30 is used to fit the first groove 2011, the cylindrical second groove fitting part 40 is used to fit the third groove 2021, and the diameter of the cylindrical first groove fitting part 30 is the same as that of the cylindrical second groove fitting part 40. In this way, when the gauge is fitted with the linear guide rail 200 and can slide relative to the linear guide rail 200, the distance E between the cylindrical first groove fitting part 30 and the cylindrical second groove fitting part 40 is measured by using a vernier caliper, and then the diameter D of the first groove fitting part 30 or the second groove fitting part 40 is added, so that the center distance A of the ball grooves is measured, that is, A = E + D. Then, whether the calculated center distance A is within the error range can be judged to determine whether the parameter meets the requirements.

[0058] Please refer to Figures 6-9 , Figure 6 is a structural schematic diagram of another first kind of state of the linear guide rail gauge 100 provided in the embodiment, Figure 7 is a structural schematic diagram of a first perspective of another second kind of state of the linear guide rail gauge 100 provided in the embodiment, Figure 8 is a structural schematic diagram of a second perspective of another second kind of state of the linear guide rail gauge 100 provided in the embodiment, Figure 9 is a structural schematic diagram of the first groove fitting part 30 and the second groove fitting part 40 provided in the embodiment.

[0059] Combination Figure 4 , Figures 6-9 For detecting the inner distance of the grooves of the linear guide rail 200, in the embodiment, the first groove fitting part 30 comprises a first cylindrical part 31 and a first protruding part 32 connected with each other, the first cylindrical part 31 is arranged in the first fitting groove 12 and is used to fit with the first groove 2011, and the first protruding part 32 is used to fit with the second groove 2012; the second groove fitting part 40 comprises a second cylindrical part 41 and a second protruding part 42 connected with each other, the second cylindrical part 41 is arranged in the second fitting groove 21 and is used to fit with the third groove 2021, and the second protruding part 42 is used to fit with the fourth groove 2022.
