[0019] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See Figure 1-3 , discloses a guide rail base surface grinding gauge, which is used to measure the guide rail base surface grinding accuracy.

[0021] like Figure 1-2 As shown, the measuring guide rail base surface grinding gauge comprises: a mounting seat 100, comprising a support body 101, a first mounting body 102 with a protrusion on one side of the support body 101, a second mounting body 105 facing the first mounting body 102 on the other side, a first convex portion 103 on the upper portion of the first mounting body 102 facing the second mounting body 105, and a second convex portion 104 on the lower portion; a movable block 200, facing the first mounting body 102, and capable of moving closer to or further away from the first mounting body The movable block 200 is provided with a third protrusion 201 on the upper part of the side close to the first mounting body 102, and a fourth protrusion 202 on the lower part; the locking device 300 is provided on the second mounting body 105, and is used to drive the movable block 200 to move toward the direction close to the first mounting body 102; the micrometer 400 is provided on the mounting base 100, and the probe 402 of the micrometer 400 extends from the direction of the support body 101 toward the direction of the movable block 200.

[0022] like Figure 3As shown, when the measuring guide rail base surface grinding gauge of the present invention is used, the guide rail to be inspected is inserted between the first mounting body 102 and the movable block 200, and the upper outer convex portion of one side of the inspected guide rail is embedded between the first convex portion 103 and the second convex portion 104, and the first convex portion 103 and the second convex portion 104 abut against the upper and lower sides of the outer convex portion of the guide rail at that location, and then the upper outer convex portion of the other side of the inspected guide rail is embedded between the third convex portion 201 and the fourth convex portion 202. The third and fourth protrusions 201 and 202 abut against the upper and lower sides of the protruding portion of the guide rail at that location. Since the upper and lower sides of the protruding portions on both sides of the upper portion of the guide rail (closer to the base surface) form a V-shaped angle with each other, when the locking device 300 drives the movable block 200 toward the first mounting body 102, the mounting seat 100 is securely positioned on the guide rail being measured. The probe 402 of the dial indicator 400 then contacts the guide rail's base surface being measured, and the mounting seat 100 is then slid along the length of the guide rail. During the sliding process of the mounting seat 100, by observing the movement of the dial indicator 400's pointer, it is possible to detect whether the accuracy of the guide rail's ground base surface meets the requirements.

[0023] like Figure 2 As shown, to meet the application requirements of the movable block 200, a sliding groove 106 with an opening facing the first mounting body 102 is provided on the side of the second mounting body 105 opposite to the first mounting body 102, and a protrusion 203 that can slide into the sliding groove 106 is provided on the side of the movable block 200 away from the first mounting body 102. Furthermore, a limiting groove 107 extending along the depth direction of the sliding groove 106 is provided on one side of the sliding groove 106, and a limiting protrusion 204 that can slide into the limiting groove 107 is provided on the protrusion 203.

[0024] Furthermore, the upper side surface of the movable block 200 is parallel to and in contact with the support body 101 .

[0025] In order to facilitate the locking device 300 to control the movable block 200, the locking device 300 includes a push rod 301 threadedly engaged with the second mounting body 105, and the end of one end of the push rod 301 abuts against the side of the movable block 200 away from the first mounting body 102.

[0026] First, the purpose of the movable block 200 being able to move away from or toward the first mounting body 102 is that when the movable block 200 is relatively far away from the first mounting body 102, the mounting base 100 can be easily pressed. Figure 3 The slide rail is set in the manner shown, and then the top rod 301 is rotated, and the top rod 301 is used to push the movable block 200 toward the guide rail to achieve a mating state in which the outer protrusions on both sides of the upper direction of the detected guide rail are respectively embedded between the first protrusion 103 and the second protrusion 104, and between the third protrusion 201 and the fourth protrusion 202.

[0027] Among them, the first convex portion 103, the second convex portion 104, the third convex portion 201, and the fourth convex portion 202 are all arc convex structures, and the convex portions can be tangent to the upper and lower sides of the convex portions on both sides of the guide rail.

[0028] Furthermore, a spring 302 is supported between the movable block 200 and the second mounting body 105. The spring 302 can actively push the movable block 200 relatively away from the first mounting body 102, so that when the movable block 200 is released during installation, the movable block 200 can naturally cooperate with the guide rail.

[0029] In order to facilitate the installation of the spring 302 , opposite insertion holes 303 are respectively provided on the movable block 200 and the second mounting body 105 , and then both ends of the spring 302 are respectively inserted into the unfilled insertion holes 303 .

[0030] In order to facilitate the installation of the micrometer 400, a through hole 108 extending toward the direction of the movable block 200 is provided on the support body 101. The handle 401 of the micrometer 400 is fixed in the through hole 108, and the probe 402 extends toward the direction of the movable block 200 after passing through the through hole 108.

[0031] Furthermore, a protrusion 109 is provided on the side of the support body 101 away from the movable block 200, and a through hole 108 passes through the protrusion 109 and the support body 101. A threaded hole 110 is provided on the side of the protrusion 109, and a screw 111 is provided on the threaded hole 110 to engage with the screw. One end of the screw 111 is inserted into the through hole 108 and abuts against the handle 401.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
