Description

Technical Field

[0001] The invention relates to a vacuum suction platform, in particular to a multifunctional vacuum suction platform, and belongs to the technical field of vacuum platform application. Background Art

[0002] Vacuuming is an essential and important process before charging refrigerant during the production or maintenance of refrigeration equipment. It is the process of connecting a vacuum pump to the refrigeration system pipeline to remove non-condensable gases and moisture from the system pipeline.

[0003] The existing vacuum suction platform simply realizes a vacuum suction function, and it is impossible to install probes on the upper and lower surfaces of the vacuum suction platform. At the same time, it is also impossible to quickly adjust the position of the probe on the vacuum suction platform. For this reason, we propose a multifunctional vacuum suction platform. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional vacuum suction platform. By installing an optical sensor head on a placement plate, the optical sensor head is placed on the upper and lower positions of the vacuum platform according to the measurement requirements. Due to the arrangement of the groove and the vacuum hole, when a clamp-type probe or different measurement modes of vacuum suction are required, the platform can be shared to solve the problem of single function of the vacuum platform in the prior art. The structure is simple and the operation is convenient. The function diversification of the vacuum platform is increased, resource consumption is saved, and production costs are reduced. By pulling the cross bar, the cross bar drives two symmetrically arranged fixed rods to move, thereby stretching the telescopic spring. After driving the limit plate to move, the fixed rod squeezes the two symmetrically arranged limit rods to move toward each other, thereby stretching the limit spring. The limit rod drives the limit block to move out of the limit groove to solve the problem of the prior art that the optical sensor head mounting plate cannot be quickly released from the limit, and the limit between the placement plate and the annular installation is quickly released. The time consumed by the staff in releasing the limit is saved, and the work efficiency is improved. By pushing the placement plate, when the placement plate moves to the required position of the optical sensing head, the force on the cross bar is released, so that the cross bar moves in the direction of the limit rod under the elastic force of the telescopic spring, thereby making the limit rod move in the direction away from the sliding block under the pulling force of the limit spring, and the limit block enters the corresponding limit groove, thereby fixing the placement plate; after the limit block enters the limit groove, the pulling force of the telescopic spring drives the cross bar to continue to move in the direction of the limit rod, thereby making the adjustment block contact with the limit rod, and the adjustment block pushes the two limit rods that are arranged oppositely to move in the opposite direction, thereby stabilizing the limit block in the limit groove, so as to solve the problem that the prior art cannot be installed quickly and stably, saves the time consumed by the staff in limiting the placement plate, increases the tightness of the limit block and the limit groove, thereby increasing the stability of the entire placement plate installation.

[0005] The object of the present invention can be achieved by the following technical solution: a multifunctional vacuum suction platform comprises an annular mounting plate, an annular plate and a disc, wherein the annular mounting plate is provided with a disc inside, and the disc is fixedly connected to the annular mounting plate;

[0006] An annular plate is sleeved and fixed on the outside of the disc inside the annular mounting plate, and the annular plate is fixedly connected to the annular mounting plate. The connecting sections of the disc and the annular plate both penetrate the top and bottom of the annular mounting plate. The tops of the disc and the annular plate are equidistantly provided with grooves and vacuum holes.

[0007] The annular mounting plate is symmetrically provided with annular grooves at the top and bottom, and a placement plate is symmetrically provided at the top and bottom of the annular mounting plate, and the bottom end of the placement plate is slidably connected in the annular groove, and the annular groove is symmetrically provided with limiting grooves on both sides, and there are several groups of symmetrically provided limiting grooves;

[0008] An optical sensor head is installed on the top of the placement plate, and a limit rod is symmetrically arranged on the bottom of the placement plate, and the limit rod is slidably connected to the placement plate;

[0009] A limiting block is symmetrically arranged in the annular slide groove, one end of the limiting block is fixedly connected to the side wall of the limiting rod away from the placement plate, and the other end of the limiting block is arranged in the corresponding limiting groove;

[0010] A cross bar is arranged in the annular slide groove, and the cross bar is slidably connected to the placement plate, an adjustment block is fixed on one side of the cross bar, and the adjustment block is located between two symmetrically arranged limit rods, fixed rods are symmetrically arranged on both sides of the adjustment block, and one end of the fixed rod is fixedly connected to the cross bar, the fixed rod is located outside the two symmetrically arranged limit rods, a limit plate is fixed to the other end of the fixed rod, and the two symmetrically arranged limit plates cooperate with the two symmetrically arranged limit rods.

[0011] A further technical improvement of the present invention is that a stabilizing block is fixed to the top of the limiting rod, a stabilizing groove is symmetrically opened at the bottom of the placement plate, the stabilizing block is slidably connected in the stabilizing groove, a limiting spring is arranged in the stabilizing groove, and both ends of the limiting spring are fixedly connected to the stabilizing block and the placement plate respectively.

[0012] A further technical improvement of the present invention is that a bottom groove is provided at the bottom of the annular slide groove, a connecting rod is slidably connected in the bottom groove, and one end of the connecting rod is fixedly connected to the placement plate.

[0013] A further technical improvement of the present invention is that: a slider is provided in the annular slide groove, the slider is fixedly connected to the cross bar, and the slider is located between the cross bar and the placement plate, a slide groove is provided at the bottom of the placement plate, the slide groove is located between two symmetrically arranged stable grooves, the slider is slidably connected in the slide groove, a telescopic spring is provided in the slide groove, and both ends of the telescopic spring are respectively fixedly connected to the slider and the placement plate.

[0014] A further technical improvement of the present invention is that the annular mounting plate, the annular plate and the disc form a vacuum platform, the diameter of the disc is eight inches, and the diameter of the annular plate is twelve inches.

[0015] A further technical improvement of the present invention is that the method for using the multifunctional vacuum suction platform comprises the following steps: when it is necessary to perform measurement on the vacuum platform, the optical sensor head is mounted on the placement plate, and the position of the optical sensor head is adjusted according to the measurement requirements;

[0016] Step 2: When the optical sensor head is adjusted, the cross bar is pulled, so that the cross bar drives the two symmetrically arranged fixed rods to move, so that the slider moves in the slide groove, thereby stretching the telescopic spring, causing the telescopic spring to deform under force and generate a reverse force. Since the two symmetrically arranged fixed rods are located on the outside of the two symmetrically arranged limit rods, after the fixed rod drives the limit plate to move, the two symmetrically arranged limit rods are squeezed to move toward each other, thereby stretching the limit spring, causing the limit spring to deform and have a reverse force, and the limit rod drives the limit block to move out of the limit groove;

[0017] Step 3: Push the placement plate to make it move in the annular slide groove. When the placement plate moves to the required position of the optical sensor head, release the force on the cross bar, so that the cross bar moves toward the direction of the limit rod under the elastic force of the telescopic spring, so that the force of the fixed rod on the limit rod disappears, so that the limit rod moves in the direction away from the slider under the pulling force of the limit spring, so that the limit block enters the corresponding limit groove, thereby fixing the placement plate;

[0018] Step 4: After the limit block enters the limit slot, the tension of the telescopic spring drives the cross bar to continue to move in the direction of the limit rod, so that the adjustment block contacts the limit rod, and the adjustment block pushes the two opposite limit rods to move in the opposite direction, thereby stabilizing the limit block in the limit slot.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the present invention is used, when it is necessary to measure on the vacuum platform, the optical sensor head is installed on the placement plate, and the optical sensor head at the upper and lower positions of the vacuum platform is placed according to the measurement requirements. Due to the arrangement of the groove and the vacuum hole, when different measurement modes such as the use of a clamp-type probe or vacuum suction are required, the platform can be shared, the structure is simple, the operation is convenient, the functional diversification of the vacuum platform is increased, resource consumption is saved, and production costs are reduced.

[0021] 2. By pulling the cross bar, the cross bar drives two symmetrically arranged fixed rods to move, thereby stretching the telescopic spring. After driving the limit plate to move, the fixed rod squeezes the two symmetrically arranged limit rods to move toward each other, thereby stretching the limit spring. The limit rod drives the limit block to move out of the limit groove, quickly releasing the limit between the placement plate and the annular installation, saving the time consumed by the staff in releasing the limit, and improving work efficiency;

[0022] 3. By pushing the placement plate, when the placement plate moves to the required position of the optical sensor head, the force on the cross bar is released, so that the cross bar moves toward the direction of the limit rod under the elastic force of the telescopic spring, so that the limit rod moves in the direction away from the slider under the pulling force of the limit spring, and the limit block enters the corresponding limit groove, thereby fixing the placement plate; after the limit block enters the limit groove, the pulling force of the telescopic spring drives the cross bar to continue to move in the direction of the limit rod, so that the adjustment block contacts the limit rod, and the adjustment block pushes the two limit rods that are set in opposite directions to move, thereby stabilizing the limit block in the limit groove, saving the time spent by the staff in limiting the placement plate, increasing the tightness of the limit block and the limit groove, thereby increasing the stability of the entire placement plate installation.

[0038] The method for using the multifunctional vacuum suction platform comprises the following steps:

[0039] Step 1: When it is necessary to perform measurement on the vacuum platform, the optical sensor head 6 is mounted on the placement plate 7, and the position of the optical sensor head 6 is adjusted according to the measurement requirements;

[0040] Step 2: When the optical sensor head 6 is adjusted, the cross bar 18 is pulled, so that the cross bar 18 drives the two symmetrically arranged fixed rods 16 to move, so that the slider 13 moves in the slide groove 12, thereby stretching the telescopic spring 23, causing the telescopic spring 23 to deform under force and generate a reverse force.

[0042] Step 4: After the limit block 19 enters the limit slot 11, the tension of the telescopic spring 23 drives the cross bar 18 to continue to move in the direction of the limit rod 17, so that the adjustment block 21 contacts the limit rod 17, and the adjustment block 21 pushes the two oppositely arranged limit rods 17 to move in the opposite direction, thereby stabilizing the limit block 19 in the limit slot 11.

Since the two symmetrically arranged fixed rods 16 are located on the outside of the two symmetrically arranged limit rods 17, after the fixed rod 16 drives the limit plate 22 to move, the two symmetrically arranged limit rods 17 are squeezed to move toward each other, thereby stretching the limit spring 15, so that the limit spring 15 is deformed and has a reverse force, and the limit rod 17 drives the limit block 19 to move out The limiting groove 11; pushes the placing plate 7 so that the placing plate 7 moves in the annular slide groove 8.
