Description

Technical Field

[0001] The present invention relates to the technical field of dimension measurement, and more particularly to a valve body component measuring device. Background Art

[0002] See also Fig.10 , which depicts a schematic diagram of the cross-sectional structure of a conventional valve body. The valve body 4 to be tested has a right pipe opening 402 connected to one side of the pipeline, a left pipe opening 403 connected to the other side of the pipeline, and an upper pipe opening 401 for installing the valve core.

[0003] The inner diameters of the upper pipe opening 401, the right pipe opening 402 and the left pipe opening 403 are important parameters that reflect the size of the valve body 4 to be tested. Measuring them is used to ensure the adaptability and performance of the valve body, and helps to confirm whether the size of the valve body meets the design specifications, thereby ensuring the fluid control ability and sealing performance of the valve body. In addition, accurate inner diameter measurement can also help detect wear or damage and avoid leakage or other failures of the valve body during operation.

[0004] In summary, during the production process of the valve body, it is very necessary to measure the inner diameters of the ports in three directions.

[0005] In the prior art, the inner diameter of the valve body is measured by an internal diameter gauge. However, since the orientations of the three ports on each valve body to be measured are different and the angle between adjacent ports is 90 degrees, the existing measuring device lacks a method for realizing the conversion of the orientations of the three ports. When measuring ports with different orientations, it is often achieved by manually changing the orientation of the internal diameter gauge. However, when changing the orientation of the internal diameter gauge, this method is difficult to adjust accurately, so that the internal diameter gauge cannot maintain a straight posture when pressed into the ports on different sides during measurement, resulting in large measurement errors. Therefore, certain improvements are needed. Summary of the invention

[0006] The present invention provides a valve body component measuring device, which solves the technical problem in the related art that it is difficult to achieve accurate conversion when measuring the inner diameters of valve body ports in different directions.

[0007] The present invention provides a valve body component measuring device, comprising a moving module, an inner diameter measuring module, a valve body clamping module, a posture switching module and a connecting arm, wherein a vertical inner diameter measuring module is fixed at one end of the connecting arm, and the other end is fixed to the output end of the moving module, and the inner diameter measuring module is controlled to move up and down and left and right through the output of the moving module, and a valve body clamping module is fixedly arranged on the output end of the posture switching module, and the valve body to be measured can be detachably arranged relative to the valve body clamping module, and when the valve body to be measured is fixedly loaded on the valve body clamping module, under the action of the posture switching module, the three ports of the valve body to be measured are turned over in sequence to be in a vertical upward posture;

[0008] The posture switching module includes a base, a carrier plate, a first driving member and a second driving member. A placement groove and a through hole are provided on the top of the base. The ends of the carrier plate are respectively fixedly mounted with a right column head and a left column head. A conversion joint matched with the first driving member is fixedly mounted at the center of the carrier plate. The right column head and the left column head are matched with the placement groove.

[0010] As a further solution of the present invention: the three ports of the valve body to be tested are respectively an upper pipe opening, a right pipe opening and a left pipe opening. When the carrier plate is placed parallel to the base, the upper pipe opening of the valve body to be tested is in a vertically upward posture. When the posture is switched, when the right column head is closed in the mounting groove by the second driving member, the upper part of the left column head is not blocked or restricted. At this time, the first driving member is started, and the carrier plate is flipped 90 degrees with the right column head as the center. After the flipping, the left pipe opening of the valve body to be tested is in a vertically upward posture. When the posture is switched again, when the left column head is closed in the mounting groove by the second driving member, the upper part of the right column head is not blocked or restricted. At this time, the first driving member is started, and the carrier plate is flipped 90 degrees with the left column head as the center. After the flipping, the right pipe opening of the valve body to be tested is in a vertically upward posture.

[0011] As a further solution of the present invention: when the posture switching module drives the upper pipe opening, right pipe opening and left pipe opening of the valve body to be tested to switch to the vertical upward posture respectively, the moving module drives the inner diameter measuring module to move left and right, so that the inner diameter measuring module and the upper pipe opening, right pipe opening and left pipe opening keep center alignment in turn.

[0012] As a further solution of the present invention: the second driving member includes a cylinder, a guide rod, a right closed frame and a left closed frame. The cylinder is arranged on one side of the base, and the guide rod is slidably arranged in the base. The guide rod is fixedly connected to the output end of the cylinder, the right closed frame is fixedly arranged at one end of the guide rod, and the left closed frame is fixedly arranged at the other end. The right closed frame slides in cooperation with the through hole on one side of the right column head, and the left closed frame slides in cooperation with the through hole on one side of the left column head.

The first connecting rod is fixedly arranged on the rotating shaft, and the second connecting rod is hingedly arranged between the end of the first connecting rod and the adapter.

[0015] As a further solution of the present invention: the movable module includes a first base, a first guide rail, a first screw rod member, a second base, a second guide rail and a second screw rod member, the first base is symmetrically fixed with the first guide rail, the first base is installed with the first screw rod member, the second base is slidably arranged on the first guide rail, the second base is matched with the output end of the first screw rod member, and under the drive of the first screw rod member, the second base slides up and down relative to the first guide rail, the second base is symmetrically fixed with the second guide rail, the second guide rail is slidably arranged with a connecting arm, the second base is installed with the second screw rod member, the output end of the second screw rod member is matched with the connecting arm, and under the drive of the second screw rod member, the connecting arm slides left and right relative to the second guide rail.

[0016] As a further solution of the present invention: a sleeve is fixedly installed at the end of the connecting arm, and the sleeve is fixedly sleeved on the outside of the inner diameter measuring module.

[0017] As a further solution of the present invention: the inner diameter measuring module includes a rod body, a probe, a meter head, a feeler rod and a transmission part. The probe is installed at one end of the rod body, and the meter head is installed at the other end. The probe is elastically connected to the feeler rod, and a transmission part is provided between the feeler rod and the meter head. When the inner diameter measuring module is in use, the rod body is vertically pressed into the port to be measured, and the feeler rod is squeezed by the inner wall of the port and retracted into the probe. The movement of the feeler rod is converted into the rotation of the pointer in the meter head through the transmission part, thereby reflecting a certain reading on the meter head.

[0018] As a further solution of the present invention: the valve body clamping module includes a fixed chuck, a slide rail, a movable chuck, an electric push rod, a traction plate and a connecting rod. The fixed chuck, the slide rail and the electric push rod are fixedly arranged on the carrier plate, the movable chuck is slidably arranged on the slide rail, the traction plate is fixedly arranged on the output end of the electric push rod, a connecting rod is fixedly arranged between the traction plate and the movable chuck, and the connecting rod is slidably interlaced with the fixed chuck.

[0019] The beneficial effects of the present invention are:

[0020] When the placement posture of the valve body to be tested is switched in the present invention, when the right column head is enclosed in the placement groove by the second driving member, the upper part of the left column head is not blocked and restricted, at this time, the first driving member is started, and the carrier plate is flipped 90 degrees with the right column head as the center of the circle, and the left pipe mouth of the valve body to be tested is in a vertical upward posture after flipping, and when the posture is switched again, when the left column head is enclosed in the placement groove by the second driving member, the upper part of the right column head is not blocked and restricted, at this time, the first driving member is started, and the carrier plate is flipped 90 degrees with the left column head as the center of the circle, and the right pipe mouth of the valve body to be tested is in a vertical upward posture after flipping, thereby providing a high-accuracy port orientation conversion method for the valve body to be tested, and assisted by the horizontal position adjustment effect applied by the moving module, the inner diameter measurement of the port in different directions can be realized without changing the measuring action mode of the inner diameter gauge, thereby effectively reducing the measurement error.

[0021] In the specific posture switching implementation structure of the present invention, when flipping in two directions is performed, that is, the right column head and the left column head are used as fulcrums respectively, the form of action in the entire first drive member remains consistent. That is to say, when flipping in different directions is achieved, it is only necessary to control the extension or retraction of the cylinder in the second drive member, and the first drive member still maintains the same rotation output direction and amplitude, thereby optimizing the control logic when performing posture switching and making it easier to implement.

[0043] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0044] At least one embodiment of the present invention discloses a valve body component measuring device, which measures the inner diameters of three ports of the valve body 4 to be measured. Figure 1 - Fig. 9 As shown, it includes a moving module 1, an inner diameter measuring module 2, a valve body clamping module 3, a posture switching module 5 and a connecting arm 6, wherein the connecting arm 6 has a vertical inner diameter measuring module 2 fixed on one end, and the other end is fixed to the output end of the moving module 1, and the inner diameter measuring module 2 is controlled to move up and down and left and right through the output of the moving module 1, and the valve body clamping module 3 is fixed on the output end of the posture switching module 5, and the valve body 4 to be tested is detachable relative to the valve body clamping module 3, and when the valve body 4 to be tested is fixedly loaded on the valve body clamping module 3, under the action of the posture switching module 5, the three ports of the valve body 4 to be tested are flipped in sequence to present a vertical upward posture.

[0045] The posture switching module 5 includes a base 51, a carrier plate 52, a first driving member 53 and a second driving member 54. A placement groove 511 and a through hole 512 are provided on the top of the base 51. A right column head 521 and a left column head 523 are fixedly installed at the ends of the carrier plate 52, respectively. An adapter 522 that cooperates with the first driving member 53 is fixedly installed at the center of the carrier plate 52. The right column head 521 and the left column head 523 are arranged in cooperation with the placement groove 511. The second driving member 54 is arranged in cooperation with the through hole 512. Under the action of the second driving member 54, the right column head 521 and the left column head 523 are successively enclosed in the placement groove 511.

[0046] The placement groove 511 is in a semicircular arc shape, and the right column head 521 and the left column head 523 are both in a regular cylindrical shape.

[0047] The three ports of the valve body 4 to be tested are respectively an upper pipe opening 401, a right pipe opening 402 and a left pipe opening 403. When the carrier plate 52 is placed parallel to the base 51, the upper pipe opening 401 of the valve body 4 to be tested is in a vertically upward posture. When the posture is switched, when the right column head 521 is closed in the mounting groove 511 by the second driving member 54, the upper part of the left column head 523 is not blocked or restricted. At this time, the first driving member 53 is started, and the carrier plate 52 is flipped 90 degrees with the right column head 521 as the center. After the flip, the left pipe opening 403 of the valve body 4 to be tested is in a vertically upward posture. When the posture is switched again, when the left column head 523 is closed in the mounting groove 511 by the second driving member 54, the upper part of the right column head 521 is not blocked or restricted. At this time, the first driving member 53 is started, and the carrier plate 52 is flipped 90 degrees with the left column head 523 as the center. After the flip, the right pipe opening 402 of the valve body 4 to be tested is in a vertically upward posture.

[0048] When the posture switching module 5 drives the upper pipe opening 401, the right pipe opening 402 and the left pipe opening 403 of the valve body 4 to be tested to switch to the vertical upward posture respectively, the moving module 1 drives the inner diameter measuring module 2 to move left and right, so that the inner diameter measuring module 2 and the upper pipe opening 401, the right pipe opening 402 and the left pipe opening 403 keep the center aligned in turn.

[0049] In general, compared with the existing inner diameter measurement method, the present invention provides a high-accuracy port orientation conversion method of the valve body 4 to be measured when dealing with the specific measurement environment of the inner diameter of the valve body, and is assisted by the horizontal position adjustment effect applied by the mobile module 1. The inner diameter measurement of ports in different orientations can be achieved without changing the measurement action mode of the inner diameter gauge, thereby effectively reducing the measurement error.

[0050] The second driving member 54 includes a cylinder 541, a guide rod 542, a right closed frame 543 and a left closed frame 544. The cylinder 541 is provided on one side of the base 51. The guide rod 542 is slidably provided in the base 51. The guide rod 542 is fixedly connected to the output end of the cylinder 541. The right closed frame 543 is fixedly provided at one end of the guide rod 542, and the left closed frame 544 is fixedly provided at the other end. The right closed frame 543 is slidably matched with the through hole 512 on one side of the right column head 521, and the left closed frame 544 is slidably matched with the through hole 512 on one side of the left column head 523. Figure 7 When the guide rod 542 moves to the right side through the positive output of the cylinder 541, the right closing frame 543 slides relative to the through hole 512 so that the upper part of the right side of the placement groove 511 is exposed, and the left closing frame 544 slides relative to the through hole 512 so that the upper part of the left side of the placement groove 511 is blocked. Figure 6 , through the reverse output of the cylinder 541, the upper part of the right side of the placement groove 511 is blocked, while the upper part of the left side of the placement groove 511 is exposed.

[0051] When the carrier plate 52 is placed parallel to the base 51 , the highest points of the right column head 521 and the left column head 523 are flush with the bottom surfaces of the right closed frame 543 and the left closed frame 544 .

[0052] The first driving member 53 includes a motor 531, an end block 532, a rotating shaft 533, a first connecting rod 534 and a second connecting rod 535. The motor 531 is fixedly arranged on one side of the base 51, and the end block 532 is symmetrically arranged on the extension line of the motor 531. The rotating shaft 533 is rotatably installed between the end blocks 532, and the end of the rotating shaft 533 is fixedly connected to the output end of the motor 531. The first connecting rod 534 is fixedly arranged on the rotating shaft 533, and the second connecting rod 535 is hingedly arranged between the end of the first connecting rod 534 and the adapter 522.

[0053] When the first driving member 53 is in use, the motor 531 drives the rotating shaft 533 to rotate. After locking one side of the carrier plate 52 (the right column head 521 or the left column head 523) as a fulcrum through the second driving member 54, the rotation of the rotating shaft 533 drives the rotation of the first connecting rod 534 and the forced rotation of the second connecting rod 535, so that the carrier plate 52 can be flipped 90 degrees.

[0054] Here, the advantage of using a connecting rod transmission structure composed of a first connecting rod 534 and a second connecting rod 535 is that when flipping in two directions (using the right column head 521 and the left column head 523 as fulcrums respectively), the form of action in the entire first drive member 53 remains consistent. That is to say, when flipping in different directions, it is only necessary to control the extension or retraction of the cylinder 541 in the second drive member 54, and the first drive member 53 still maintains the same rotation output direction and amplitude, thereby optimizing the control logic when switching postures and making it easier to implement.

[0055] The mobile module 1 includes a first base 11, a first guide rail 12, a first screw rod 13, a second base 14, a second guide rail 15 and a second screw rod 16. The first base 11 is symmetrically fixed with the first guide rail 12, the first base 11 is equipped with the first screw rod 13, the first guide rail 12 is slidably provided with the second base 14, the second base 14 is matched with the output end of the first screw rod 13, and under the drive of the first screw rod 13, the second base 14 slides up and down relative to the first guide rail 12, the second base 14 is symmetrically fixed with the second guide rail 15, the second guide rail 15 is slidably provided with a connecting arm 6, the second base 14 is equipped with the second screw rod 16, the output end of the second screw rod 16 is matched with the connecting arm 6, and under the drive of the second screw rod 16, the connecting arm 6 slides left and right relative to the second guide rail 15.

[0056] After the posture switching of the valve body 4 to be tested is realized by using the posture switching module 5, the placement position of the valve body 4 to be tested will be offset in the horizontal and vertical directions. The offset in the vertical direction has little effect. It is mainly the horizontal upward offset that causes the inner diameter measurement module 2 and the various ports of the valve body 4 to be tested to no longer be center-aligned. In order to eliminate this adverse effect, the inner diameter measurement module 2 fixed on the connecting arm 6 is driven by the second screw rod 16 to move left and right to balance the horizontal displacement deviation caused by the posture switching, and the first screw rod 13 controls the inner diameter measurement module 2 to move up and down, which is coordinated with the use of the inner diameter measurement module 2 to drive the inner diameter measurement module 2 to be pressed into the various ports of the valve body 4 to be tested for measurement.

[0057] A sleeve 60 is fixedly mounted on the end of the connecting arm 6 , and the sleeve 60 is fixedly sleeved on the outside of the inner diameter measuring module 2 .

[0058] It should be noted that the control of linear motion by the first screw rod 13 and the second screw rod 16 is a mature existing technology, similar to an XY axis moving platform, and therefore its specific structure will not be expanded here.

[0059] The inner diameter measuring module 2 comprises a rod body 201, a probe 202, a meter head 203, a feeler rod 204 and a transmission member 205. The probe 202 is installed at one end of the rod body 201, and the meter head 203 is installed at the other end. The probe 202 is elastically connected with the feeler rod 204, and a transmission member 205 is provided between the feeler rod 204 and the meter head 203. When the inner diameter measuring module 2 is in use, the rod body 201 is vertically pressed into the port to be measured (the upper pipe port 401, the right pipe port 402 and the left pipe port 403), and the feeler rod 204 is squeezed by the inner wall of the port and retracted into the probe 202. The movement of the feeler rod 204 is converted into the rotation of the pointer in the meter head 203 through the transmission member 205, so that a certain reading is reflected on the meter head 203.

[0060] Regarding the specific implementation of the transmission member 205 mentioned above, reference may be made to the internal diameter micrometer, micrometer, etc. in the prior art, which will not be elaborated here.

[0061] The valve body clamping module 3 includes a fixed chuck 31, a slide rail 32, a movable chuck 33, an electric push rod 34, a traction plate 35 and a connecting rod 36. The fixed chuck 31, the slide rail 32 and the electric push rod 34 are fixedly arranged on the carrier plate 52. The movable chuck 33 is slidably arranged on the slide rail 32. The traction plate 35 is fixedly arranged on the output end of the electric push rod 34. A connecting rod 36 is fixedly arranged between the traction plate 35 and the movable chuck 33. The connecting rod 36 slides and intersects with the fixed chuck 31.

[0062] When loading the valve body 4 to be tested, the valve body 4 to be tested is placed in the gap between the fixed clamp 31 and the movable clamp 33, and then the movable clamp 33 is driven by the electric push rod 34 to slide relative to the slide rail 32, so that the movable clamp 33 approaches the fixed clamp 31, thereby fixing and clamping the valve body 4 to be tested, waiting for measurement.

[0063] How it works

[0064] Before measuring the inner diameter of each port of the valve body 4 to be tested, the valve body 4 to be tested is first fixedly loaded, and the valve body 4 to be tested is placed in the gap between the fixed clamp 31 and the movable clamp 33, and then the movable clamp 33 is driven by the electric push rod 34 to slide relative to the slide rail 32, so that the movable clamp 33 approaches the fixed clamp 31, thereby fixing and clamping the valve body 4 to be tested, waiting for measurement. The three ports of the valve body 4 to be tested are the upper pipe port 401, the right pipe port 402 and the left pipe port 403. When the carrier plate 52 is placed parallel to the base 51, the valve body 4 to be tested is fixedly loaded. The upper pipe opening 401 of the valve body 4 is in a vertical upward posture. When the posture is switched, when the right column head 521 is closed in the placement groove 511 by the second driving member 54, the upper part of the left column head 523 is not blocked. At this time, the first driving member 53 is started, and the carrier plate 52 is turned 90 degrees with the right column head 521 as the center. After the turning, the left pipe opening 403 of the valve body 4 to be tested is in a vertical upward posture. When the posture is switched again, when the left column head 523 is closed in the placement groove 511 by the second driving member 54, the upper part of the right column head 521 is not blocked. The first driving member 53 is activated at this time, and the carrier plate 52 is turned 90 degrees with the left column head 523 as the center. After the turning, the right pipe opening 402 of the valve body 4 to be tested is in a vertical upward posture. When the posture switching module 5 drives the upper pipe opening 401, the right pipe opening 402 and the left pipe opening 403 of the valve body 4 to be tested to switch to the vertical upward posture respectively, the moving module 1 drives the inner diameter measuring module 2 to move left and right, so that the inner diameter measuring module 2 is aligned with the upper pipe opening 401, the right pipe opening 402 and the left pipe opening 403 in sequence. Then the first screw rod 13 controls the inner diameter measuring module 2 to move up and down, driving the inner diameter measuring module 2 to press into each port of the valve body 4 to be measured for measurement. When the inner diameter measuring module 2 is in use, the rod body 201 is vertically pressed into the port to be measured (the upper pipe port 401, the right pipe port 402 and the left pipe port 403), and the feeler rod 204 is squeezed by the inner wall of the port and retracts into the measuring head 202. The movement of the feeler rod 204 is converted into the rotation of the pointer in the meter head 203 through the transmission member 205, thereby reflecting a certain reading on the meter head 203.

[0065] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation mode. The above-mentioned specific implementation mode is merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make more forms of equivalent embodiments, all of which are within the protection of this embodiment.
