Description

Technical Field

[0001] The utility model relates to the technical field of connecting handle components, and more specifically to a three-coordinate dimension measuring tool. Background Art

[0002] The reactor control rod cluster assembly is a tool for quickly controlling the nuclear reactivity of the reactor. It is used to adjust the reactor power during normal operation and quickly introduce negative reactivity under accident conditions to shut down the reactor in an emergency, thereby ensuring nuclear safety. The reactor control rod cluster assembly consists of a connecting handle component and an absorbent rod. The connecting handle component is as follows: Figure 1 As shown, it comprises a connecting handle 01, a wing plate 02 and a finger rod 03, wherein the wing plate 02 and the finger rod 03 form a wing plate assembly.

[0003] The connecting handle component is one of the components with the most complex dimensional features in the reactor control rod cluster assembly. The connecting handle component has nearly 100 features that need to be measured, among which there are many complex fitting shape surfaces and form and position tolerances. Some dimensions of the connecting handle component need to be positioned on a three-dimensional coordinate measuring machine for measurement.

[0004] In the prior art, a three-dimensional coordinate measuring machine is usually equipped with a V-shaped iron block for positioning the part to be tested. When measuring, the part to be tested, such as the connecting handle part, is clamped on the V-shaped iron block, and then the measurement is performed. When the operator clamps the connecting handle part, it is necessary to ensure that the position of the connecting handle part can satisfy the same position of the wing plate and each finger rod in the measurement space each time the connecting handle part is clamped. Since the V-shaped iron block in the prior art does not have a positioning function, the position of the connecting handle part on the V-shaped iron block needs to be repeatedly adjusted each time it is placed and clamped, and it is not easy to ensure that the wing plate and each finger rod are the same in the measurement space, resulting in low measurement accuracy and efficiency.

[0005] Therefore, how to improve measurement accuracy and measurement efficiency has become a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0043] The core of the utility model is to provide a three-coordinate dimension measuring tool to improve the measurement accuracy and measurement efficiency.

[0044] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0045] The embodiment of the utility model discloses a three-coordinate dimension measuring tool, which is used for the dimension measurement of a connecting handle component, so that the connecting handle component can be quickly and accurately positioned on a three-coordinate measuring machine, so as to improve the measurement accuracy and efficiency, and avoid the problems of low measurement accuracy and low measurement efficiency caused by the difficulty in positioning in the prior art and the need to repeatedly adjust the position of the connecting handle component.

[0046] like Figure 2-Figure 4 As shown, the three-coordinate dimension measuring tool disclosed in the embodiment of the utility model includes a base 100, a clamping seat 300, a clamping plate 400 and a spatial positioning member 200. Among them, the base 100 is used to be fixed to the workbench of the three-coordinate measuring machine. Specifically, the bottom of the base 100 may have a support table 103 with a larger footprint, so as to have a larger contact area with the workbench of the three-coordinate measuring machine and improve the stability of the fixation. Fastening holes may be provided on the support table 103, and fasteners may be used to clamp it on the workbench of the three-coordinate measuring machine. It should be noted that the clamping form of the base 100 on the three-coordinate measuring machine can be arbitrary, and the base 100 can be fixed according to the clamping structure of the three-coordinate measuring machine itself.

[0047] The clamping seat 300 is disposed on the base 100, and the top of the clamping seat 300 has a clamping groove 301 for supporting the connecting handle of the connecting handle component. The clamping seat 300 can be disposed on the base 100 in a direct or indirect manner, and the connecting handle of the connecting handle component is supported in the clamping groove 301. The clamping groove 301 can be disposed on the top of the clamping seat 300, and the opening side of the clamping groove 301 is located at the top, so that the connecting handle can be placed in the clamping groove 301 through the top opening.

[0048] The clamping plate 400 is detachably fixed to the top of the clamping seat 300, and is used to close the open side of the clamping groove 301, so as to clamp the connecting handle in the clamping groove 301. In this embodiment, by adding the clamping plate 400, the connecting handle supported in the clamping groove 301 can be pressed tightly to prevent the connecting handle from sliding in the clamping groove 301 and causing scratches on the connecting handle component.

[0049] The spatial positioning member 200 is disposed at one end of the base 100 along the extension direction of the clamping groove 301, and is used to position the wing plate assembly of the connecting handle component. Specifically, the wing plate assembly of the connecting handle component can be positioned, and specifically, the finger rod of the wing plate assembly can be positioned, and the wing plate of the wing plate assembly can also be positioned, as long as the wing plate assemblies of the connecting handle component can be constrained at a specific position by the spatial positioning member 200.

[0050] The three-coordinate dimension measuring tool provided by the utility model is installed on the workbench of the three-coordinate measuring machine through the base 100 when in use. The connecting handle of the connecting handle component is placed in the clamping groove 301 of the clamping seat 300, and then the wing plate assembly of the connecting handle component is positioned by the spatial positioning member 200 to ensure that the wing plates and each finger rod of the wing plate assembly are accurately positioned in the measuring space. After the positioning is completed, the connecting handle of the connecting handle component is pressed by the clamping plate 400 to complete the clamping of the connecting handle component on the three-coordinate dimension measuring tool. After the clamping of the connecting handle component is completed, the spatial positioning member 200 is removed, and the probe of the three-coordinate measuring machine measures the size of the connecting handle component. The utility model can enable the orientation of the connecting handle component on the three-coordinate measuring machine to be quickly and accurately positioned, thereby improving the accuracy of the measurement; and the connecting handle component can be accurately clamped to the measuring orientation at one time, and the clamping efficiency is high.

[0051] In a specific embodiment of the utility model, the spatial positioning member 200 is a positioning plate, and the spatial positioning member 200 is slidably arranged on the base 100 along the height direction of the base 100, and is fixed to the base 100 by a locking member, and the spatial positioning member 200 is used to support the wing plate assembly of the connecting handle component. It should be noted that the locking member is a locking top screw, and a screw hole matching the locking top screw is arranged on the spatial positioning member 200, and the locking is achieved by the locking top screw abutting against the wall surface of the base 100.

[0052] When clamping the connecting handle component, slide the spatial positioning member 200 to the height of the positioning wing plate assembly, and then lock the spatial positioning member 200 through the locking member so that the spatial positioning member 200 is fixed at this height. Then place the connecting handle of the connecting handle component in the clamping groove 301 of the clamping seat 300, rotate the connecting handle component so that one of the wing plates of the wing plate assembly is perpendicular to the plate surface of the spatial positioning member 200 and abuts against the plate surface of the spatial positioning member 200, then the positioning of the wing plate assembly measurement orientation is completed, and then the connecting handle of the connecting handle component is pressed by the clamping plate 400, so that the measurement orientation of the wing plate assembly can be locked.

[0053] After the clamping plate 400 is tightened, the locking piece is loosened so that the locking piece is separated from the wall of the base 100, and the spatial positioning piece 200 is unlocked. The spatial positioning piece 200 is slid downward so that the spatial positioning piece 200 leaves the wing plate assembly of the connecting handle component to prevent the spatial positioning piece 200 from affecting the measurement of the three-dimensional coordinate measuring machine.

[0054] In order to improve the stability of the spatial positioning member 200 sliding up and down, in this embodiment, first guide sliding parts 101 are provided on both side walls of the base 100 parallel to the extension direction of the clamping groove 301, and the first guide sliding parts 101 extend along the height direction of the base 100. It should be noted that the number of the first guide sliding parts 101 on each side wall of the base 100 can be one or multiple first guide sliding parts 101 arranged in parallel.

[0055] The space positioning member 200 has a second guide sliding portion 202 that is slidably matched with the first guide sliding portion 101. The first guide sliding portion 101 and the second guide sliding portion 202 are slidably matched, so that the space positioning member 200 can only slide along the extension direction of the first guide sliding portion 101. At the same time, the first guide sliding portion 101 and the second guide sliding portion 202 are slidably matched, and the freedom of the space positioning member 200 in other directions can also be limited by the slidable match between the first guide sliding portion 101 and the second guide sliding portion 202, so as to prevent the space positioning member 200 from being separated from the base 100.

[0056] The first guide sliding part 101 divides the base 100 into a base main body and a base sliding part 102, and the space positioning member 200 is arranged on one side of the base sliding part 102. Since the space positioning member 200 needs to be covered on the outside of the base sliding part 102, the width of the base sliding part 102 should be smaller than that of the base main body.

[0057] The space positioning member 200 has a clamping arm 201 on the side facing the base 100, and the clamping arm 201 is clamped on both sides of the base sliding portion 102, and the second guide sliding portion 202 is arranged at the end of the clamping arm 201. It should be noted that the first guide sliding portion 101 should extend to the top of the base 100, and the space positioning member 200 can be installed from the top of the base 100, and the second guide sliding portion 202 and the first guide sliding portion 101 are matched at the top of the base 100, and then slide to the bottom of the base 100, and then the clamping seat 300 is installed on the top of the base 100.

[0058] The structure of the clamping arm 201 on the side of the space positioning member 200 facing the base 100 can be formed by slotting the plate surface of the space positioning member 200 or by fixing the clamping arm 201 on the space positioning member 200. The locking member can be installed on the clamping arm 201, and the locking member is used to tighten on the base sliding part 102.

[0059] In this embodiment, the first guide sliding part 101 is a slide groove, and the second guide sliding part 202 is a slider that slides with the slide groove. It should be noted that the first guide sliding part 101 can also be a slide rail, and the second guide sliding part 202 is a slide groove that slides with the slide rail.

[0060] It should be noted that the spatial positioning member 200 can also be fixed to the base 100 and / or the clamping seat 300 in a detachable manner. For example, when the spatial positioning member 200 needs to be positioned, the spatial positioning member 200 can be fixed to the base 100 and / or the clamping seat 300 by fasteners, and after the positioning is completed and the connecting handle component is pressed by the clamping plate 400, the spatial positioning member 200 can be removed.

[0061] In addition to the positioning plate disclosed in the above embodiment, the spatial positioning member 200 uses the positioning plate to abut against one of the wing plate assemblies so that the wing plate of the wing plate assembly is perpendicular to the spatial positioning member 200, thereby achieving the effect of positioning the connecting handle component. The positioning of each wing plate assembly can also be achieved by means of positioning holes, for example, positioning holes corresponding to the wing plate assemblies of the connecting handle component are provided on the spatial positioning member 200. That is, the spatial positioning member 200 can also be designed as a plate-like structure, but this plate-like structure needs to be perpendicular to the axis of the connecting handle component, and positioning holes corresponding to the wing plate assemblies of the connecting handle component are provided on the spatial positioning member 200. Specifically, the positioning holes can only cooperate with the finger rods of the wing plate assemblies.

[0062] When clamping the connecting handle component, after each wing plate assembly of the connecting handle component is aligned with the positioning holes on the spatial positioning member 200, and each finger rod is inserted into the positioning hole, the connecting handle of the connecting handle component is placed in the clamping groove 301, and the positioning of the measuring position of the wing plate assembly is completed. Then, the connecting handle of the connecting handle component is pressed by the clamping plate 400, and the measuring position of the wing plate assembly can be locked. After the clamping plate 400 completes the pressing, the spatial positioning member 200 can be removed, so that the spatial positioning member 200 is separated from the wing plate assembly of the connecting handle component to prevent the spatial positioning member 200 from affecting the measurement of the three-dimensional coordinate measuring machine.

[0063] In a specific embodiment of the utility model, a first clamping seat sliding portion 104 is provided on the top of the base 100, and the extension direction of the first clamping seat sliding portion 104 is parallel to the extension direction of the clamping groove 301. The bottom of the clamping seat 300 has a second clamping seat sliding portion 302 that is slidably matched with the first clamping seat sliding portion 104. That is, in this embodiment, the clamping seat 300 is arranged on the top of the base 100 in a sliding manner. Such an arrangement can facilitate the replacement of the clamping seat 300, so that other types of clamping seats 300 can be arranged on the base 100 in a push-pull sliding manner according to needs.

[0064] It should be noted that the clamping seat 300 can also be fixed to the top of the base 100 by means of fasteners, or can be directly designed as an integrated structure with the base 100.

[0065] Further, the first clamping seat sliding part 104 can be a slide groove, and the first clamping seat sliding part 104 includes a limiting groove body and a guiding groove body, the limiting groove body is connected to the guiding groove body, the limiting groove body is located at the lower side of the guiding groove body, and the width of the limiting groove body is greater than the width of the guiding groove body. Preferably, the limiting groove body and the guiding groove body can be in a vertical state, that is, the first clamping seat sliding part 104 is an inverted T-shaped groove structure.

[0066] The second clamping seat sliding part 302 may be a slide rail, and the second clamping seat sliding part 302 includes a limit rail body that is slidably matched with the limit groove body, and a guide rail body that is slidably matched with the guide groove body. When the first clamping seat sliding part 104 is an inverted T-shaped groove structure, the second clamping seat sliding part 302 is an inverted T-shaped rail structure. In this embodiment, the first clamping seat sliding part 104 and the second clamping seat sliding part 302 are designed as the above structure, which can limit the clamping seat 300 from being separated from the base 100 in the height direction, so that the clamping seat 300 can only slide along the extension direction of the first clamping seat sliding part 104.

[0067] In a specific embodiment of the present invention, the clamping plate 400 includes a plate main body and plate assembly parts located at both ends of the plate main body. The plate assembly parts are fixed to the clamping seat 300 by plate fasteners, and accordingly, the top of the clamping seat 300 also has a clamping seat assembly part corresponding to the plate assembly part, and the clamping seat assembly parts are arranged on both sides of the clamping groove 301.

[0068] A clamping seat threaded hole that cooperates with the pressure plate fastener needs to be opened on the clamping seat assembly part, and a pressure plate fastening hole corresponding to the clamping seat threaded hole is opened on the pressure plate assembly part. After the pressure plate fastener passes through the pressure plate fastening hole, the thread is matched with the clamping seat threaded hole. By tightening the pressure plate fastener, the pressure plate assembly part can be pressed using the nut of the pressure plate fastener, so that the clamping pressure plate 400 is pressed on the connecting handle.

[0069] The main body of the pressure plate is arranged opposite to the clamping groove 301, and extends in a direction away from the clamping groove 301 to form an outward expansion groove 402 connected to the clamping groove 301, and the connecting handle is clamped in the clamping groove 301 and the outward expansion groove 402. Since the connecting handle is a cylindrical structure, after the connecting handle is placed in the clamping groove 301, the connecting handle will protrude from the open side of the clamping groove 301, so the outward expansion groove 402 is provided on the clamping pressure plate 400, so that the connecting handle can be pressed, otherwise the depth of the clamping groove 301 needs to be increased. If the outward expansion groove 402 is not provided on the clamping pressure plate 400, the depth of the clamping groove 301 can be increased so that the upper surface of the connecting handle is flush with the open side of the clamping groove 301, and then the clamping pressure plate 400 is installed to achieve pressing.

[0070] In this embodiment, the opening side of the outward expansion groove 402 is arranged facing the clamping groove 301, and the width of the outward expansion groove 402 gradually decreases from the opening side to the groove bottom side. Correspondingly, the opening side of the clamping groove 301 is located at the top of the clamping seat 300, and the width of the clamping groove 301 gradually decreases from the opening side to the groove bottom side.

[0071] Figure 4 In the illustrated solution, the clamping groove 301 is a V-shaped groove with an opening punched upward, and the outward expansion groove 402 is a trapezoidal groove with an opening punched downward. It should be noted that the present embodiment does not limit the width of the clamping groove 301. The clamping groove 301 is designed as a V-shaped groove, so that after the connecting handle is placed in the clamping groove 301, the two side walls of the clamping groove 301 can clamp the outer peripheral surface of the connecting handle, and the position of the connecting handle in the clamping groove 301 is located at a position where the width of the clamping groove 301 is equal to the diameter of the connecting handle.

[0072] It should be noted that the clamping plate 400 with the outer expansion grooves of different depths can be selected to adapt to the connecting handles of different diameters. Similarly, the clamping seat 300 with the clamping grooves 301 of different sizes can also be selected.

[0073] like Figure 2As shown, there are a plurality of clamping plates 400 arranged at intervals along the extending direction of the clamping groove 301 . Figure 2 In the illustrated solution, there are two clamping plates 400, and along the extension direction of the clamping slot 301, the two clamping plates 400 are respectively arranged at the top ends of the clamping slot 301. It should be noted that only one clamping plate 400 can also be provided, arranged in the middle of the top of the clamping slot 301.

[0074] In a specific embodiment of the utility model, a pressure plate fastening hole for the pressure plate fastener to pass through is provided on the pressure plate assembly portion, and the pressure plate fastening hole is a strip fastening hole 401, and the extension direction of the strip fastening hole 401 is parallel to the extension direction of the clamping groove 301, so that the clamping pressure plate 400 can be fine-tuned in the extension direction of the clamping groove 301 to adjust the clamping position of the clamping pressure plate 400 on the connecting handle.
