Description

Technical Field

[0001] The present application relates to the field of extracting the stator-rotor clearance gauge of a compressor, and particularly to a tooling for extracting the stator-rotor clearance gauge of a compressor. Background Art

[0002] The compressor stator-rotor clearance gauge, abbreviated as the clearance gauge and also known as the umbrella gauge, is a tooling for the clearance assembly of the compressor stator and rotor. As Figure 1 shown, it is a common clearance gauge 100. When in use, it can perform clearance assembly on the stator and rotor of the compressor, but it will be placed inside the compressor itself. Therefore, after the clearance gauge 100 is used, it needs to be pulled out from it. Currently, the commonly used extraction method is to use equipment to extract the handle head 300 at the upper end of the handle rod 200 at the top of the clearance gauge 100, so as to pull out the entire clearance gauge 100. However, due to the fact that some stator-rotor clearances are too small or the thickness of the clearance piece 400 of the clearance gauge 100 is relatively large, a relatively large pulling force is required.

[0003] As Figure 2 shown, it is a currently commonly used tooling for extracting the clearance gauge, which includes a bracket 500, two jaws 600 rotatably connected to the bracket, and a tension spring 700 for connecting the two jaws. When in use, the handle head 300 at the top of the clearance gauge 100 pushes the two jaws 600 apart, and then enters between the two jaws 600. Then, the two jaws 600 reset under the pulling force of the tension spring 700, so that the two jaws 600 clamp the handle rod 200, and then the bracket 500 is pulled up, and the two jaws 600 pull out the clearance gauge 100.

[0004] However, when using the tooling for extracting the clearance gauge 100 as Figure 2 shown, since the two jaws 600 fix and extract the clearance gauge 100 through the pulling force of the tension spring 700, and the two jaws 600 are rotatably connected to the bracket, when the two jaws 600 extract the clearance gauge, due to the relatively large force required to extract the clearance gauge 100, while the pulling force of the tension spring 700 is limited, therefore, when using this equipment to extract the clearance gauge 100, the clearance gauge 100 is likely to slip out of the two jaws 600, resulting in the failure of extracting the clearance gauge 100. Therefore, there is a phenomenon that some clearance gauges cannot be extracted by the equipment, so it needs to be processed after being discovered manually. This not only reduces the extraction speed and efficiency of the clearance gauge, but also makes the extraction success rate of the clearance gauge relatively low. At the same time, the labor intensity of manual extraction is relatively large, the speed is slow, and the efficiency is low, resulting in a relatively low efficiency of the entire production line. Summary of the Invention

[0005] In order to improve the speed and efficiency of extracting the gap gauge, and to improve the success rate of extracting the gap gauge, the present application provides a tool for extracting the stator and rotor gap gauge of a compressor, which allows the handle head at the top of the gap gauge to extend into the interior of a gate frame through two extracting claws, and then the gate frame is lifted to allow the two extracting claws to extract the handle head of the gap gauge, thereby extracting the entire gap gauge. The tool is not only simple in structure and easy to operate, but also improves the speed and efficiency of extracting the gap gauge and greatly improves the success rate of extracting the gap gauge.

[0006] The present application provides a tool for extracting the gap gauge between the stator and rotor of a compressor, which adopts the following technical solution:

[0007] A tool for extracting a gap gauge between a stator and a rotor of a compressor, comprising:

[0008] Door frame;

[0009] Two rotating shafts are both rotatably connected to the portal frame and are respectively located at the bottom of both sides of the portal frame, and the two rotating shafts are distributed in parallel;

[0010] Two claws are rotatably connected to the two rotating shafts respectively, and the two claws are located in the middle of the door frame and are arranged opposite to each other. The two claws are used to cooperate to extract the handle of the gap gauge; and

[0011] The limiting part is formed at the bottom of the side end of the portal frame and is used to limit the pulling claw so that the pulling claw can maintain a horizontal state to pull out the gap gauge.

[0012] Preferably, a torsion spring for keeping the claw in a horizontal state is sleeved on the rotating shaft, one end of the torsion spring is fixedly connected to the door frame, and the other end of the torsion spring is fixedly connected to the claw.

[0013] Preferably, a giving way portion for giving way to the rotation of the claw is formed on the portal frame, and an abutting portion for abutting against the giving way portion is formed on the claw.

[0014] Preferably, the number of torsion springs sleeved on each of the rotating shafts is two, and the two torsion springs are respectively distributed on both sides of the portal frame.

[0015] Preferably, when the two claws are kept in a horizontal state, the distance between the two claws is less than or equal to the diameter of the handle.

[0016] Preferably, the upper end of the portal frame is connected to a lifting cylinder, and the piston rod of the lifting cylinder is fixedly connected to the top of the portal frame.

[0017] Preferably, a push cylinder for pushing the gap gauge out from the two claws is provided on one side of the portal frame, and the push cylinder is located on one side of the portal frame.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] 1. The present invention allows the handle head at the top of the gap gauge to extend into the interior of the gate frame through two claws, and then lifts the gate frame to allow the two claws to extract the handle head of the gap gauge, thereby extracting the entire gap gauge. The tooling is not only simple in structure and easy to operate, but also improves the speed and efficiency of extracting the gap gauge and greatly improves the success rate of extracting the gap gauge.

[0021] 3. In the present application, the distance between the two pullers is kept in a horizontal state so as to be less than or equal to the diameter of the handle rod. When the two pullers are pulling out the handle head, due to the downward pulling force of the gap gauge, the two pullers will clamp the handle rod, so that the two pullers form a self-locking relationship, thereby improving the stability when pulling out the gap gauge and improving the success rate of pulling out the gap gauge.

In the present application, a torsion spring is sleeved on the rotating shaft so that the puller claw can better maintain a horizontal state, and after the puller claw is pushed open by the handle of the gap gauge, the puller claw can be quickly reset to maintain a horizontal state, so that it can quickly rise to extract the handle of the gap gauge, and then the entire gap gauge is pulled out. Not only is the speed fast and efficient, but the success rate of extracting the gap gauge is also high, and the production efficiency of the entire production line for extracting the gap gauge is improved.

DETAILED DESCRIPTION

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] An embodiment of the present application discloses a tooling for extracting a compressor stator-rotor clearance gauge.

[0030] Referring to Figure 3 and Figure 4 , the tooling includes a gantry 1, a rotating shaft 2, a pulling claw 3, and a limiting portion 11.

[0031] The gantry 1 is in a gantry shape.

[0032] The number of the rotating shafts 2 is two. The two rotating shafts 2 are both rotatably connected to the gantry 1, and the two rotating shafts 2 are respectively located at the bottoms on both sides of the gantry 1. At the same time, the two rotating shafts 2 are parallelly distributed, and the rotating shaft 2 is perpendicular to the gantry 1.

[0033] Referring to Figure 3 and Figure 4 , the number of the pulling claws 3 is also two. The two pulling claws 3 are respectively rotatably connected to the two rotating shafts 2, and the two pulling claws 3 are located at the middle position of the gantry 1, and the two pulling claws 3 are oppositely arranged. When in use, the two pulling claws 3 are used in cooperation to extract the handle head 300 of the clearance gauge 100.

[0034] In order to enable the two pulling claws 3 to smoothly extract the clearance gauge 100, and at the same time avoid the clearance gauge 100 falling off from the two pulling claws 3 during the rising process, when the two pulling claws 3 are in a horizontal state, the distance between the two pulling claws 3 is slightly less than or equal to the diameter of the handle rod of the clearance gauge 100, that is, the shortest distance between the two pulling claws 3 is slightly less than or equal to the diameter of the handle rod of the clearance gauge 100. In this way, when the two pulling claws 3 extract the clearance gauge 100, since an upward force is required to extract the clearance gauge 100, and plus the gravity of the clearance gauge 100 itself, therefore, the clearance gauge 100 will pull the two pulling claws 3 downward. Since the shortest distance between the two pulling claws 3 is slightly less than or equal to the diameter of the handle rod of the clearance gauge 100, therefore, the two pulling claws 3 will clamp the handle rod of the clearance gauge 100, that is, a self-locking will be formed between the two pulling claws 3, thereby improving the success rate and stability of extracting the clearance gauge 100.

[0035] The limiting portion 11 is formed on the gantry 1, and the limiting portion 11 is located at the bottom of the side end of the gantry 1. The limiting portion 11 is used to limit the rotation angle of the pulling claw 3. When in use, the limiting portion 11 can limit the pulling claw 3 to keep the pulling claw 3 in a horizontal state, and then extract the clearance gauge 100.

[0036] Referring to Figure 3 and Figure 4In order to make the claw 3 rotate better on the rotating shaft 2, a giving portion 12 for giving way to the rotation of the claw 3 is formed on the inner end of the portal frame 1, and the giving portion 12 is inclined. An abutment portion 31 is formed on the end surface of the claw 3 close to the inner end of the portal frame 1. When in use, the abutment portion 31 can abut against the giving portion 12 during the rotation of the claw 3. At this time, the claw 3 is at the maximum rotation angle. Therefore, the claw 3 can rotate in the area between the limiting portion 11 and the giving portion 12.

[0037] When in use, the upper end of the portal frame 1 is connected to the lifting cylinder 5, which is used to drive the portal frame 1 to rise and fall. A horizontal push cylinder 6 is provided on one side of the portal frame 1. The push cylinder 6 can push out the gap gauge 100 pulled out by the two claws 3, and make the gap gauge 100 detach from the two claws 3 and fall onto the conveyor line or the conveyor belt of the conveying device.

[0038] Further, refer to Figure 3 and Figure 4 In order to keep the claw 3 in a better horizontal state and to quickly reset the claw 3 to keep it in a horizontal state after being pushed open by the gap gauge 100, a torsion spring 4 is sleeved on the rotating shaft 2, one end of the torsion spring 4 is fixedly connected to the door frame 1, and the other end of the torsion spring 4 is fixedly connected to the claw 3. At the same time, in order to maintain the stability and balance of the claw 3, two torsion springs 4 are sleeved on each rotating shaft 2, and the two torsion springs 4 are respectively located on both sides of the door frame 1.

[0039] When in use, the entire tooling is placed vertically. Under the action of gravity, the torsion spring 4 and the limiting part 11, the two claws 3 are kept in a horizontal state. The gap gauge 100 of the installed compressor stator and rotor is placed directly under the door frame 1, and then the piston rod of the lifting cylinder 5 is extended to drive the door frame 1 to descend. As the door frame 1 descends, the handle head 300 on the top of the gap gauge 100 pushes the two claws 3 open. As the door frame 1 gradually descends, the handle head 300 on the top of the gap gauge 100 gradually and completely enters the interior of the door frame 1, and then the two claws 3 are gradually reset and abutted against the handle rod 200 under the action of gravity and the torsion spring 4, and then the lifting and lowering The piston rod of the cylinder 5 retracts and drives the portal frame 1 to rise. With the rise of the portal frame 1 and the downward pulling force of the gap gauge 100 on the two claws 3, the two claws 3 gradually clamp the handle rod of the gap gauge 100, and a self-locking is formed between the two claws 3. Then, the handle head 300 on the top of the gap gauge 100 is driven to rise during the rise of the two claws 3, so that the gap gauge 100 is pulled out. After the piston rod of the lifting cylinder 5 is completely retracted, the piston rod of the push cylinder 6 can be extended, and the piston rod of the push cylinder 6 pushes the gap gauge 100 from the two claws 3, so that the gap gauge 100 is separated from the two claws 3 and falls onto the conveyor line or the conveyor belt of the conveying device.

[0040] Compared with the traditional tooling for extracting the clearance gauge 100, this tooling greatly improves the success rate of extracting the clearance gauge 100, almost achieving a 100% success rate. Moreover, it has a simple structure, is easy to operate, and at the same time reduces the labor intensity of manually extracting the clearance gauge 100.

[0041] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
