Description

Technical Field

[0001] This invention relates to the field of precision measurement technology for vacuum pump housing parts, specifically to a device for simultaneously detecting the distance between multiple end faces of a vacuum pump housing. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and create a vacuum. Vacuum pumps require a backing pump to operate and can achieve high pumping speeds over a wide pressure range. They are not sensitive to dust and water vapor in the gas being evacuated. Vacuum pumps are often manufactured by mounting the device inside a housing. During the production of the vacuum pump housing, the distance between its multiple end faces needs to be tested to determine whether the distance between the multiple end faces is up to standard.

[0003] Existing multi-segment end face distance detection devices for vacuum pump housings are mostly inconvenient to position between the device and the housing during use, which can easily lead to positional deviations during the detection process. This can cause deviations in the data from the detection probe, resulting in inaccurate detection values ​​and reduced practicality of the device. It is difficult to guarantee the accuracy of multi-segment end face distance detection, and the detection time is relatively long. Therefore, this solution proposes a device for simultaneous detection of multi-segment end face distance of vacuum pump housings. Summary of the Invention

[0042] Reference Figure 1-13As shown, a device for simultaneously detecting the distance between multiple end faces of a vacuum pump housing is proposed. It includes a worktable 1, with support legs 2 fixedly installed at each of the four corners of the bottom of the worktable 1. A first limiting mechanism 3 is provided on the upper left side of the worktable 1. Two support limiting frames 4 are provided on the left side of the first limiting mechanism 3, and both support limiting frames 4 are fixedly installed on the upper wall of the worktable 1.

A pushing mechanism 9 is provided on the vertical moving mechanism 6. A second limiting mechanism 11 is provided at the bottom of the pushing mechanism 9. A bracket 10 is provided at the bottom of the vertical moving mechanism 6. Both the bracket 10 and the second limiting mechanism 11 are fixedly installed on the upper wall of the workbench 1. A limiting pin 101 is fixedly installed on the top right side of the bracket 10.

[0043] The housing 13 is placed on the first limiting mechanism 3, and the housing 13 is limited by the cooperation of the first limiting mechanism 3 and the support limiting frame 4. The housing 13 is tested by setting the left groove surface gauge 122, right groove surface gauge 123 and right side wall gauge 124 corresponding to the mating groove 133, the detection wall 134 and the right side wall 135. During the test, the gap and parallelism between the mating groove 133, the detection wall 134 and the right side wall 135 and the left groove surface gauge 122, the right groove surface gauge 123 and the right side wall gauge 124 can be judged by the detection probe 125.

The movable tip 351 passes through the through hole 34 and is positioned to contact one side of the housing 13 with the help of the through hole 34, so that the housing 13 can better contact the multi-segment end face distance simultaneous detection mechanism 12, thereby enabling higher distance accuracy.

[0045] The horizontal moving mechanism 5 includes a horizontal slide rail 51, a horizontal slider 52, a square plate 53, a cylinder seat 54, a groove 55, a horizontal cylinder 56, and a connecting plate 57. The horizontal slide rail 51 is fixedly installed on the upper wall of the workbench 1. The horizontal slider 52 is slidably connected to the horizontal slide rail 51. There are two horizontal slide rails 51, and a square plate 53 is placed between the two horizontal slide rails 51. A cylinder seat 54 is fixedly connected to the top right side of the square plate 53. A groove 55 is opened on the top of the cylinder seat 54, and a horizontal cylinder 56 is placed in the groove 55. The left side of the horizontal cylinder 56... A connecting plate 57 is fixedly installed at the end. When the horizontal cylinder 56 is activated, it drives the connecting plate 57 to move horizontally, causing the vertical moving mechanism 6 to move horizontally under the push of the connecting plate 57. The vertical moving mechanism 6 drives the horizontal slider 52 to slide on the horizontal slide rail 51, making the vertical moving mechanism 6 slide more stably under the push of the horizontal moving mechanism 5, and less prone to deviation. This ensures that the vertical moving mechanism 6 is more stable when it drives the multi-segment end face distance detection mechanism 12 to move horizontally to contact the housing 13 to perform multi-segment end face distance detection.

[0046] The vertical moving mechanism 6 includes a plate 61. A mounting groove 611 is provided on the top of the plate 61.

A limit slot 612 is provided on the left side of the plate 61, and a limit post 101 is movably connected within the limit slot 612. A vertical plate 62 and a supporting triangular plate 63 are fixedly connected from left to right on the top of the plate 61. Supporting triangular plates 63 are fixedly connected to both the front and rear ends of the right side of the vertical plate 62, and the vertical plate 62 is fixedly connected to a connecting plate 57. Vertical slide rails 64 are fixedly installed on both the front and rear ends of the left side of the vertical plate 62, and slidably connected to the vertical slide rails 64. A vertical slider 65 is provided, and a slide plate 66 is fixedly installed on the left side of the vertical slider 65. A vertical groove 661 is opened at the bottom of the slide plate 66. A horizontal plate 67 is fixedly connected to the left side of the slide plate 66. The horizontal plate 67 is moved horizontally by the vertical moving mechanism 6. When the front side of the horizontal plate 67 abuts against the support frame 33, the vertical moving mechanism 6 has moved the multi-segment end face distance simultaneous detection mechanism 12 towards the housing 13 to a fixed position. The multi-segment end face distance simultaneous detection mechanism 12 and the housing 13 are positioned to ensure that the position is not easily deviated during the detection process, thereby ensuring the accuracy of the data of the detection probe 125 and making the detection value of the equipment more accurate.

[0047] The pushing mechanism 9 includes a carrying plate 91, a vertical cylinder 92, and a limiting block 93. The carrying plate 91 is fixedly installed on the right side of the upright plate 62. The vertical cylinder 92 is fixedly installed on the top of the carrying plate 91. The output end of the vertical cylinder 92 passes through the carrying plate 91 and is fixedly connected to the limiting block 93. The left end of the limiting block 93 passes through the through groove 621 and is fixedly connected to the slide plate 66. When the vertical cylinder 92 is activated, it drives the limiting block 93 to move vertically, thereby driving the slide plate 66 to move vertically under the auxiliary limiting of the vertical slide rail 64. When the bottom of the limiting block 93 abuts against the first abutment 113 and the top of the vertical groove 661 abuts against the second abutment 114 at the same time, the detection probe 125 completes the multi-segment end face distance detection of the housing 13.

[0048] The second limiting mechanism 11 includes a second support frame 111, an electric telescopic rod 112, a first abutment joint 113, and a second abutment joint 114. The second support frame 111 is fixedly installed at the bottom left side of the upright plate 62. The electric telescopic rod 112 is fixedly installed at the bottom left side of the second support frame 111. The output end of the electric telescopic rod 112 passes through the second support frame 111 and is fixedly connected to the first abutment joint 113. The second abutment joint 114 is provided on the right side of the first abutment joint 113 and is fixedly installed on the support frame 111. On the upper wall of frame 211, abutment 113 corresponds one-to-one with limit block 93, and abutment 214 corresponds one-to-one with vertical groove 661. The abutment 113 and abutment 214 cooperate with limit block 93 to limit the multi-segment end face distance simultaneous detection mechanism 12. When abutment 113 extends or retracts, it can cooperate with vertical cylinder 92 to drive slide plate 66 to move vertically, making the multi-segment end face distance simultaneous detection mechanism 12 on it more stable when performing multi-segment end face detection.

[0049] This embodiment refers to Figure 1 and Figure 4 As shown in the figure, the housing workpiece corresponding to the testing equipment is provided. A front mounting surface 131 is provided on the lower front side of the housing 13. A side plate 132 is provided on the right side of the housing 13. Several mating grooves 133 are provided on the front side of the housing 13. A testing wall 134 is provided on the right side of the mating grooves 133. A right side wall 135 is provided on the right side of the housing 13.

[0050] Specifically, the multi-segment end-face distance simultaneous detection mechanism 12 includes a mounting base 121, a left groove surface gauge 122, a right groove surface gauge 123, a right side wall gauge 124, and detection probes 125. The multi-segment end-face distance simultaneous detection mechanism 12 can detect the housing 13 with a tolerance requirement of ±0.01mm. It simultaneously detects multiple dimensional distances with an accuracy of 0.0001mm through several detection probes 125. Several mounting bases 121 are provided, and all mounting bases 121 are fixedly installed on the left side of the slide plate 66. The left groove surface gauge 122, the right groove surface gauge 123, and the right side wall gauge 124 are respectively provided on the left side of the mounting bases 121. Detection probes are provided on one side of the left groove surface gauge 122, the right groove surface gauge 123, and the right side wall gauge 124. 125, the left groove surface gauge 122 corresponds one-to-one with the left side wall of the mating groove 133, the left groove surface gauge 122 corresponds one-to-one with the right side wall of the mating groove 133, one of the right groove surface gauges 123 corresponds one-to-one with the detection wall 134, and the detection probe 125 corresponds one-to-one with the right side wall 135. The multi-segment end face distance detection mechanism 12 approaches the housing 13 under the joint action of the horizontal moving mechanism 5, the vertical moving mechanism 6 and the pushing mechanism 9, and the detection probe 125 set on the left groove surface gauge 122, the right groove surface gauge 123 and the right side wall gauge 124 contacts the mating groove 133, the detection wall 134 and the right side wall 135, so as to quickly determine whether the multi-segment end face distance of the mating groove 133, the detection wall 134 and the right side wall 135 meets the standard.

[0051] Working principle: First, the equipment is calibrated to absolute values ​​using standard parts. Then, the housing 13 is placed on the vacuum pump housing multi-segment end face distance simultaneous detection device. The housing 13 is fixed by the cooperation of the first limiting mechanism 3 and the support limiting frame 4. The horizontal cylinder 56 is activated, which drives the connecting plate 57 to move horizontally. This causes the vertical moving mechanism 6 to move horizontally under the push of the connecting plate 57. The movement of the vertical moving mechanism 6 drives the horizontal plate 67 to move horizontally. When the front side of the horizontal plate 67 abuts against the support frame 33, the vertical moving mechanism 6 has driven the multi-segment end face distance simultaneous detection mechanism 12 to move towards the housing 13 to a fixed position. The multi-segment end face distance simultaneous detection mechanism 12 and the housing... Positioning is achieved between the bodies 13. The vertical cylinder 92 is activated, causing it to drive the limiting block 93 to move vertically. This causes the slide plate 66 to move vertically under the auxiliary limiting of the vertical slide rail 64. When the bottom of the limiting block 93 abuts against the first abutment 113 and the top of the vertical groove 661 abuts against the second abutment 114 at the same time, the detection probe 125 completes the detection of the distance between multiple end faces of the housing 13. By using the detection probes 125 set on the left groove surface gauge 122, the right groove surface gauge 123, and the right side wall gauge 124 to contact the mating groove 133, the detection wall 134, and the right side wall 135, it is possible to quickly determine whether the distance between the multiple end faces of the mating groove 133, the detection wall 134, and the right side wall 135 meets the standard.

[0052] In summary, the advantages of this invention are: it proposes a device for simultaneous detection of the distance between multiple end faces of a vacuum pump housing, which has high detection efficiency and can complete the detection of the distance dimensions of multiple segments of the vacuum pump housing in 3-5 seconds. It can ensure the accuracy requirements of the distance between the multiple end faces of the vacuum pump housing and the inspection requirements of batch products on the production line. The results can guide the adjustment and compensation of processing equipment to achieve 100% closed-loop detection of production and inspection of products.
