Description

Technical Field

[0001] This application relates to the field of parallelism detection technology, and more specifically to a guide rail parallelism detection fixture. Background Technology

[0002] Currently, portal frames or crossbeams are commonly used as mounting bases, with upper and side guide rail structures installed on these bases. The upper guide rail structure includes an upper guide rail mounting surface, an upper guide rail recessed surface, and the upper guide rail itself. The upper guide rail recessed surface is located on one side of the upper guide rail mounting surface. The upper guide rail is detachably fixed to the upper guide rail mounting surface, with its side abutting against the upper guide rail recessed surface. The side guide rail structure includes a side guide rail mounting surface, a side guide rail recessed surface, and the side guide rail itself. The side guide rail recessed surface is located on one side of the side guide rail mounting surface. The side guide rail is detachably fixed to the side guide rail mounting surface, with its side abutting against the side guide rail recessed surface.

[0003] The upper guide rail extends horizontally in both its length and width directions. The side guide rail is located below the upper guide rail, with its length extending horizontally and its width extending vertically.

[0004] However, during the installation of the upper guide rail and the side guide rail, due to errors in installation accuracy, it is necessary to check the parallelism of the upper guide rail structure relative to the side guide rail structure in order to adjust the installation accuracy.

[0005] Therefore, how to improve the detection accuracy of the parallelism between the side guide rail structure and the upper guide rail structure remains a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, to solve the above-mentioned technical problems, this application provides a guide rail parallelism testing fixture for auxiliary testing of a fixed seat that is simultaneously provided with an upper guide rail structure and a side guide rail structure. The guide rail parallelism testing fixture includes:

[0007] The connecting frame has a first connecting arm and a second connecting arm connected together; the second connecting arm is located below the first connecting arm and together with the first connecting arm form a semi-enclosed space that avoids the fixed seat; the fixed seat is provided with an upper guide rail structure and a side guide rail structure.

[0008] The slider is connected to the first connecting arm and is located inside the semi-enclosed space for sliding along the upper guide rail structure.

[0009] The counterweight is connected to the first connecting arm and is located on the side of the slider away from the second connecting arm;

[0010] And a detector mounting bracket, located on the second connecting arm, is used to connect a parallelism detector, so as to detect the parallelism of the side guide rail structure relative to the upper guide rail structure by means of a probe of the parallelism detector facing the side guide rail structure.

[0011] Beneficial effects: Unlike existing technologies, in this application, when the slider slides along the upper guide rail structure, it can drive the connecting frame to move, causing the probe of the parallelism detector mounted on the detector mounting frame to slide synchronously along the side guide rail structure, thereby realizing the detection of the parallelism between the side guide rail structure and the upper guide rail structure. Furthermore, when the slider slides in the upper guide rail structure, the first connecting arm is supported on the slider. At this time, the weight of the counterweight can be used to balance the weight borne by the portion of the first connecting arm located on the side of the slider closer to the second connecting arm, thus ensuring that the weight borne by the portions of the first connecting arm on both sides of the slider is not too different. This facilitates the smooth sliding of the slider along the upper guide rail structure, thereby improving the detection accuracy of the parallelism between the side guide rail structure and the upper guide rail structure.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Furthermore, all directional indications (such as up, down, left, right, front, back, horizontal, and vertical) in the embodiments of this application are only used to interpret a specific posture (as shown in the attached diagram). Figure 3 The relative positions and movements of the components shown below are considered. If the specific posture changes, the directional indication will also change accordingly.

[0024] Example 1

[0025] Please see Figures 1-3 As shown, the guide rail parallelism detection fixture 10 includes a connecting frame 100, a slider 200, a counterweight 300, and a detector mounting frame 400.

[0026] The connecting frame 100 has a first connecting arm 110 and a second connecting arm 120 connected together. The second connecting arm 120 is disposed below the first connecting arm 110 and together with the first connecting arm 110 forms a semi-enclosed space 101 that avoids the fixed seat 20. The fixed seat 20 is provided with an upper guide rail structure 30 and a side guide rail structure 40. A slider 200 is connected to the first connecting arm 110 and is located inside the semi-enclosed space 101 for sliding along the upper guide rail structure 30. A counterweight 300 is connected to the first connecting arm 110 and is located on the side of the slider 200 away from the second connecting arm 120. A detector mounting bracket 400 is disposed on the second connecting arm 120 for connecting a parallelism detector (not shown) to detect the parallelism of the side guide rail structure 40 relative to the upper guide rail structure 30 by means of a probe of the parallelism detector facing the side guide rail structure 40.

[0027] In this way, when the slider 200 slides along the upper guide rail structure 30, it can drive the connecting frame 100 to move, so that the probe of the parallelism detector mounted on the detector mounting frame 400 slides synchronously along the side guide rail structure 40, thereby realizing the detection of the parallelism between the side guide rail structure 40 and the upper guide rail structure 30. Furthermore, when the slider 200 slides in the upper guide rail structure 30, the first connecting arm 110 is supported on the slider 200. At this time, the weight of the counterweight 300 can be used to balance the weight borne by the part of the first connecting arm 110 located on the side of the slider 200 near the second connecting arm 120, so that the weight borne by the parts of the first connecting arm 110 on both sides of the slider 200 is not too different, which is beneficial to the smooth sliding of the slider 200 along the upper guide rail structure 30, thereby improving the detection accuracy of the parallelism between the side guide rail structure 40 and the upper guide rail structure 30.

[0028] Specifically, the first connecting arm 110 has a first part (not shown) and a second part (not shown). The first part is the portion of the first connecting arm 110 located on the side of the slider 200 away from the second connecting arm 120, and the second part is the portion of the first connecting arm 110 located on the side of the slider 200 closer to the second connecting arm 120. A counterweight 300 is disposed on the first part, and the second connecting arm 120 is connected to the second part. At this time, the weight of the counterweight 300 is used to balance the weight borne by the second part, so that the weight difference between the first part and the second part is not too large. This allows the center of gravity of the entire structure of the guide rail parallelism detection fixture 10, except for the slider 200, to be positioned close to the slider 200. This avoids or reduces the situation where the force on the side of the slider 200 closer to the second connecting arm 120 is significantly greater than that on the side of the slider 200 away from the second connecting arm 120, thus facilitating the smooth sliding of the slider 200 along the upper guide rail structure 30.

[0029] Optionally, when the probe of the parallelism detector slides along the side guide rail structure 40, the probe can extend or retract along the deformation of the surface of the side guide rail structure 40, so that the parallelism detector instrument indicates a value for measuring the parallelism of the side guide rail structure 40 relative to the upper guide rail structure 30.

[0030] It should be noted that the parallelism detector is existing technology, and it can be a dial indicator, a micrometer, or other instruments that can detect the parallelism between the side guide rail structure 40 and the upper guide rail structure 30, which will not be described in detail here.

[0031] Optionally, such as Figures 1-3 As shown, the counterweight unit 300 includes a counterweight mounting bracket 310 and a counterweight 320. The counterweight mounting bracket 310 is provided with a counterweight placement slot 311. The counterweight 320 is disposed in the counterweight placement slot 311, and the counterweight 320 is detachably connected to the counterweight mounting bracket 310. Thus, the counterweight 320 can be appropriately added or removed according to the weight borne by the second part of the first connecting arm 120.

[0032] Optionally, the opening of the counterweight placement slot 311 faces away from the outer side of the first connecting arm 110 and the semi-enclosed space 101. This facilitates the placement of the counterweight 320 into the counterweight placement slot 311.

[0033] Optionally, such as Figures 1-3 As shown, the guide rail parallelism detection fixture 10 includes a support arm 500, one end of which is connected to a first connecting arm 110, and the other end of which is connected to a second connecting arm 120. The semi-enclosed space 101 is located on the side of the support arm 500 away from the first connecting arm 110 and the second connecting arm 120.

[0034] In the above manner, the support arm 500 supports the first connecting arm 110 and the second connecting arm 120 respectively, thus maintaining the shape stability of the semi-enclosed space 101. Optionally, the first connecting arm 110, the second connecting arm 120, and the support arm 500 form a triangular space (not shown in the figure) on the side of the support arm 500 closest to the first connecting arm 110 and the second connecting arm 120, thereby utilizing the stability of the triangle to improve the shape stability of the semi-enclosed space 101. The semi-enclosed space 101 can be formed on the side of the support arm 500 away from the first connecting arm 110 and the second connecting arm 120.

[0035] Optionally, such as Figures 1-3 As shown, the detector mounting bracket 400 is provided with a first magnetic attraction part (not shown), and the parallelism detector is provided with a second magnetic attraction part (not shown). The first magnetic attraction part can be magnetically attracted to the second magnetic attraction part to detachably fix the parallelism detector to the detector mounting bracket 400.

[0036] By using the above method, the parallelism detector can be installed quickly and conveniently by attracting the first magnetic part and the second magnetic part together.

[0037] Optionally, the first magnetic attraction part is a permanent magnet, and the second magnetic attraction part can be attracted by the permanent magnet. Alternatively, the first magnetic attraction part can be attracted by the permanent magnet, and the second magnetic attraction part is a permanent magnet. The first or second magnetic attraction part that can be attracted by the permanent magnet can be an object made of iron, cobalt, nickel, or another permanent magnet. The permanent magnet can be a permanent magnet.

[0038] It should be noted that in other examples, the first magnetic attraction part can also be an electromagnet, and the second magnetic attraction part can be attracted by the electromagnet. Alternatively, the first magnetic attraction part can be attracted by the electromagnet, and the second magnetic attraction part is an electromagnet.

[0039] Optionally, combined Figures 4-6 See Figures 1-3 As shown, the upper guide rail structure 30 includes an upper guide rail mounting surface 31, an upper guide rail recessed surface 32, and an upper guide rail 33 on the fixed base 20. The upper guide rail recessed surface 32 is located on one side of the upper guide rail mounting surface 31. The upper guide rail 33 is detachably fixed to the upper guide rail mounting surface 31, and the side of the upper guide rail 33 abuts against the upper guide rail recessed surface 32. The slider 200 includes a first slider 200a and a second slider 200b.

[0040] The first slider 200a is connected to the first connecting arm 110. The first slider 200a has a bottom surface 201a for sliding along the upper guide rail mounting surface 31 and a side surface 202a for sliding along the upper guide rail abutment surface 32. The second slider 200b is detachably connected to the lower side of the first slider 200a. The second slider 200b is provided with a guide rail groove 201b, which is used to slide in cooperation with the upper guide rail 33 so that the second slider 200b slides along the upper guide rail 33.

[0041] In the first state, the second slider 200b can slide along the upper guide rail 33. The first state includes the second slider 200b being detachably connected to the lower side of the first slider 200a, and the upper guide rail 33 being detachably fixed to the upper guide rail mounting surface 31, with the side of the upper guide rail 33 abutting against the upper guide rail recessed surface 32. In the second state, the first slider 200a can slide along both the upper guide rail mounting surface 31 and the upper guide rail recessed surface 32. The second state includes the second slider 200b being removed from the first slider 200a, and the upper guide rail 33 being removed from the upper guide rail mounting surface 31. Thus, either the first slider 200a or the second slider 200b can be selected to slide along the upper guide rail structure 30, depending on the actual situation.

[0042] Optionally, combined Figures 4-6 See Figures 1-3As shown, the side guide rail structure 40 includes a side guide rail mounting surface 41, a side guide rail recessed surface 42, and a side guide rail 43. The side guide rail recessed surface 42 is located on one side of the side guide rail mounting surface 41. The side guide rail 43 is detachably fixed to the side guide rail mounting surface 41, and the side of the side guide rail 43 abuts against the side guide rail recessed surface 42.

[0043] The upper guide rail 33 extends horizontally in both its length and width directions. The side guide rail 43 is located below the upper guide rail 33, and its length extends horizontally while its width extends vertically.

[0044] In the third state, the probe can slide along the surface of the side guide rail 43. The third state includes the side guide rail 43 being detachably fixed to the side guide rail mounting surface 41, with the side of the side guide rail 43 abutting against the side guide rail recessed surface 42. In the fourth state, the probe can slide along either the side guide rail mounting surface 41 or the side guide rail recessed surface 42. The fourth state includes the side guide rail 43 being detached from the side guide rail mounting surface 41.

[0045] Optionally, combined Figures 1-6 See Figure 8 As shown, the first slider 200a extends along the direction intersecting with the first connecting arm 110, protruding from both sides of the first connecting arm 110. Each portion of the first slider 200a protruding from both sides of the first connecting arm 110 is provided with a first connecting hole 203a. The first connecting hole 203a penetrates the bottom surface 201a of the slider. The second slider 200b is detachably connected to the first connecting hole 203a via a connector (not shown). This design effectively maintains the flatness of the bottom surface 201a of the slider, facilitating smooth sliding of the bottom surface 201a along the upper guide rail mounting surface 31.

[0046] In one example, the connector may be a protrusion provided on the second slider 200b protruding toward the first slider 200a, so that the connector can be detachably inserted into the first connecting hole 203a.

[0047] In another example, the connector can be a bolt or a combination of a screw and a nut to connect the first slider 200a and the second slider 200b via a threaded connection. Specifically, the second slider 200b extends in a direction intersecting the first connecting arm 110 to protrude from both sides of the first connecting arm 110. The second slider 200b, protruding from both sides of the first connecting arm 110 and located away from the guide rail groove 201b, has a second connecting hole 202b corresponding to the first connecting hole 203a. The connector is detachably connected to both the first connecting hole 203a and the second connecting hole 202b.

[0048] Optionally, such as Figures 1-3As shown, in one other example, slider 200 may include a first slider 200a but not a second slider 200b. In yet another example, slider 200 may include a second slider 200b but not the first slider 200a, the second slider 200b being connected to the first connecting arm 110.

[0049] Optionally, such as Figures 1-3 The length direction of the first connecting arm 110 extends horizontally; the length direction of the second connecting arm 120 extends vertically, but is not limited thereto.

[0050] Optionally, the first connecting arm 110 and the second connecting arm 120 are integrally formed, thus the connecting frame 100 has higher mechanical strength. Optionally, the first connecting arm 110 and the second connecting arm 120 are separately formed, which facilitates the preparation of the first connecting arm 110 and the second connecting arm 120.

[0051] Optionally, the mounting base 20 can be a portal bridge 20a.

[0052] Example 2

[0053] Example 2 is a variation of Example 1. The parts that are the same as those in Example 1 will not be repeated. The difference between Example 2 and Example 1 is that the fixed seat 20 is a crossbeam 20b.

[0054] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
