Description

Technical Field

[0001] The present invention relates to a detection device, in particular to an automatic detection device for vacuum pump pressure. Background Art

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physicochemical methods to evacuate the container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain a vacuum in a closed space.

[0003] The usual method for pressure testing a vacuum pump is to connect the vacuum pump to a test container, then put the gas to be tested in, and continuously pump the gas for a long time. When the gas pressure in the container no longer drops and maintains a certain value, this pressure is called the ultimate vacuum of the pump, also called the vacuum degree. The smaller the value, the closer it is to the theoretical vacuum. Currently, when testing a vacuum pump, the staff directly connects the vacuum pump's exhaust pipe to the detector, resulting in poor sealing. During the inspection process, gas is easy to leak out, which can easily affect the test results.

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1

[0031] A vacuum pump pressure automatic detection device, see Figures 1-6 As shown, it includes a base 1, a fixed rod 2, a guide rod 3, a slide 4, a mounting frame 5, a detector 6, a moving mechanism 7 and a cover placement mechanism 8. The fixed rod 2 is symmetrically arranged on the left and right sides of the top front side of the base 1 by welding, and the guide rod 3 is symmetrically fixed to the left and right sides of the top rear side of the base 1. The slide 4 is slidably arranged between the two fixed rods 2 and the two guide rods 3. The mounting frame 5 is slidably arranged on the upper part of the guide rod 3, and the detector 6 is installed in the mounting frame 5. The moving mechanism 7 is arranged on the left and right sides of the base 1, and the cover placement mechanism 8 is arranged on the upper part of the guide rod 3.

[0032] See Figure 1 、 Figure 3 and Figure 4 As shown, the moving mechanism 7 includes a support frame 701, a motor 702, a first gear 703 and a first rack 704. The support frames 701 are fixedly connected on the left and right sides of the base 1. The motor 702 is installed on the support frame 701. The first gear 703 is provided on the output shaft of the motor 702 through a key connection. The first racks 704 are fixedly connected on the left and right sides of the middle part of the skateboard 4. The first gear 703 is engaged with the adjacent first rack 704.

[0033] See Figure 1 、 Figure 5 and Figure 6As shown, the cover placing mechanism 8 includes a fixing frame 801, a connecting rod 802, a clamping block 803, a first elastic member 804 and a leak-proof cover 805. The upper part of the guide rod 3 is fixedly connected to the fixing frame 801, and the fixing frame 801 is located below the detector 6. Two connecting rods 802 are fixedly connected to the inner sides of the two fixing frames 801. A clamping block 803 is slidingly arranged between the two adjacent connecting rods 802. A first elastic member 804 is connected between the connecting rod 802 and the clamping block 803. The first elastic member 804 is sleeved on the connecting rod 802. The first elastic member 804 is a compression spring. The compression spring can better drive the clamping block 803 to reset. A leak-proof cover 805 is provided on the clamping block 803.

[0034] When the device is to be used, the staff places the vacuum pump on the slide plate 4 so that the vacuum pump's exhaust pipe is aligned with the detector 6. Then the staff moves the clamping block 803 inward, and the first elastic member 804 is compressed. The clamping block 803 moves inward, driving the leak-proof cover 805 to move inward, so that the two leak-proof covers 805 contact each other. Then the staff turns on the motor 702, and the output shaft of the motor 702 drives the first gear 703 to rotate. The first gear 703 drives the first rack 704 to move upward. The first rack 704 moves upward, driving the slide plate 4 and the vacuum pump to move upward, so that the vacuum pump's exhaust pipe enters between the two leak-proof covers 805. At this time, the staff presses down the mounting bracket 5, and the mounting bracket 5 moves downward, driving the detector 6 to move downward, so that the detector 6 is sleeved on the two leak-proof covers 805. At this time, the staff turns off the motor 702, and then the staff connects the external pipe to the detector 6. Then the staff turns on the vacuum pump, so that the vacuum pump continuously exhausts for a long time. When the gas pressure in the detector 6 is When it no longer decreases and maintains a certain value, this pressure is called the vacuum degree of the vacuum pump. The staff can check the vacuum degree of the vacuum pump by observing the value on the detector 6. When the device is no longer needed, the staff will turn off the vacuum pump, and then the staff will disconnect the external pipe. Then the staff will turn on the motor 702 again. The staff will control the output shaft of the motor 702 to reverse. The output shaft of the motor 702 drives the first gear 703 to reverse. The reversal of the first gear 703 drives the first rack 704 to move downward. The first rack 704 drives the slide plate 4 and the vacuum pump to move downward and reset, so that the vacuum pipe of the vacuum pump is disengaged from the two leak-proof covers 805. At the same time, the worker moves the mounting frame 5 upward to drive the detector 6 to move upward, so that the detector 6 is disengaged from the leak-proof cover 805. At this time, the first elastic member 804 is reset to drive the clamping block 803 and the leak-proof cover 805 to move outward and reset. Then the staff can take out the vacuum pump and repeat the above operations. The device can be used again to perform pressure detection on the vacuum pump.

[0035] Example 2

[0036] Based on Example 1, see Figure 1 and Figure 7As shown, it also includes a pushing mechanism 9, which includes a support seat 901, a push block 902, a second elastic member 903 and an extrusion block 904. The left and right sides of the slide plate 4 are symmetrically fixed with support seats 901, and a push block 902 is slidably provided on the upper part of the support seat 901. A second elastic member 903 is connected between the support seat 901 and the push block 902. The second elastic member 903 is sleeved on the push block 902, and an extrusion block 904 is slidably provided on the fixed rod 2. The same extrusion block 904 is slidably provided on the lower part of the guide rod 3, and the extrusion block 904 is in contact with the adjacent push block 902.

[0037] After the staff places the vacuum pump on the slide 4, the staff moves the squeezing block 904 downward, and the squeezing block 904 squeezes the push block 902 to move inward, and the second elastic member 903 is compressed accordingly. The push block 902 moves inward so as to push the vacuum pump so that it is located in the middle position of the slide 4, which is convenient for pressure detection. The staff then releases the squeezing block 904, and the second elastic member 903 drives the push block 902 to move outward and reset. The push block 902 moves outward to squeeze the squeezing block 904 and move it upward and reset.

[0038] See Figure 1 and Figure 8 As shown, it also includes an extrusion mechanism 11, which includes an extrusion frame 1101 and a wedge block 1102. The extrusion frame 1101 is symmetrically fixed to the left and right sides of the top rear side of the slide 4. The extrusion frame 1101 is slidably connected to the adjacent guide rod 3. The wedge blocks 1102 are provided on the front and rear sides of the clamping block 803 by welding. When the extrusion frame 1101 moves upward, the wedge block 1102 will be squeezed to move.

[0039] See Figure 1 and Figure 9 As shown, it also includes a lifting mechanism 12, which includes a second rack 1201, a fixed sleeve 1202, a second gear 1203 and a third rack 1204. The second rack 1201 is fixedly connected to the upper part of the first rack 704, and the fixed sleeve 1202 is fixedly connected to the upper part of the guide rod 3. The fixed sleeve 1202 is located above the fixed frame 801. A second gear 1203 is rotatably provided on the fixed sleeve 1202, and the second gear 1203 cooperates with the adjacent second rack 1201. The third rack 1204 is fixedly connected to the left and right sides of the front side of the mounting frame 5, and the second gear 1203 is meshed with the adjacent third rack 1204.

[0040] When the first rack 704 moves upward, the first rack 704 drives the second rack 1201 to move upward, so that the second rack 1201 is engaged with the second gear 1203, and the second rack 1201 drives the second gear 1203 to rotate. The rotation of the second gear 1203 drives the third rack 1204 to move downward, and the downward movement of the third rack 1204 drives the mounting bracket 5 and the detector 6 to move downward. At the same time, the upward movement of the first rack 704 drives the slide 4, the vacuum pump and the extrusion rack 1101 to move upward, so that the extrusion rack 1101 moves upward to extrude the wedge block 1102 to drive the clamping block 803 to move inward, and the clamping block 803 drives the leak-proof cover 805 moves inward, thus achieving the purpose of automatically connecting the vacuum pump's exhaust pipe, the leak-proof cover 805 and the detector 6. When the first rack 704 moves downward, the first rack 704 drives the slide 4, the vacuum pump and the extrusion frame 1101 to move downward and reset. At the same time, the first rack 704 drives the second rack 1201 to move downward, the second rack 1201 drives the second gear 1203 to reverse, and the second gear 1203 reverses and drives the mounting frame 5 and the detector 6 to move upward and reset through the third rack 1204. At this time, the first elastic member 804 resets and drives the clamping block 803, the leak-proof cover 805 and the wedge block 1102 to move outward and reset.

[0041] See Figure 1 、 Figure 10 and Figure 11 As shown, an exhaust mechanism 13 is also included, and the exhaust mechanism 13 includes a support rod 1301, a baffle 1302 and a third elastic member 1303. The left and right sides of the detector 6 are symmetrically fixed with support rods 1301, and a baffle 1302 is slidingly arranged between two adjacent support rods 1301. A group of exhaust holes 1304 are opened on the left and right sides of the detector 6, and the baffle 1302 is used to block the exhaust holes 1304. A third elastic member 1303 is connected between the baffle 1302 and the support rod 1301, and the third elastic member 1303 is sleeved on the support rod 1301.

[0042] When the exhaust pipe and the leak-proof cover 805 are connected to the detector 6, the air in the detector 6 is squeezed, causing the baffle 1302 to move outward and disengage from the exhaust hole 1304, and the third elastic member 1303 is compressed accordingly. At this time, the air in the detector 6 can be discharged outward through the exhaust hole 1304. After the air is discharged, the third elastic member 1303 resets and drives the baffle 1302 to move inward to block the exhaust hole 1304 again.
