[0040] In order to make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0041] Figure 1 It is a front view schematic diagram of a fixing device according to an embodiment of the utility model; Figure 2 It is a schematic top view of a fixing device according to an embodiment of the utility model.

[0042] like Figure 1 and Figure 2 As shown, one embodiment of the utility model provides a fixing device 100 for decomposing a compressor gas valve, and the fixing device 100 includes:

[0043] Workbench 110;

[0044] The positioning member 120 is disposed on the workbench 110 and is inserted into the columnar hole of the compressor valve. The positioning member 120 fixes the compressor valve and the positioning member 120 is clearance-matched with the columnar hole.

[0045] Among them, the fixing device 100 for disassembling the compressor valve includes a workbench 110, and the compressor valve can be placed on the workbench 110 for disassembly, thereby improving the stability of the compressor valve disassembly; at the same time, a positioning piece 120 is arranged on the workbench 110, and by inserting the positioning piece 12 into the cylindrical hole of the compressor valve, two positioning pieces 120 are usually arranged to improve the positioning stability of the compressor valve, and at the same time, positioning can be achieved by utilizing the existing cylindrical hole, thereby simplifying the structure of the fixing device 100, reducing the cost of the fixing device 100, and further reducing the disassembly cost; the positioning piece 120 is matched with the gap of the cylindrical hole, so that the compressor valve can be inserted into the positioning piece 120 more quickly, further reducing the difficulty of disassembly and improving the disassembly efficiency; finally, through the fixing device 100, one person can complete the disassembly of the compressor valve, which, on the one hand, reduces the number of staff required for disassembly and reduces the disassembly cost, and on the other hand, the fixing device 100 of the present application can also reduce the work intensity of a single staff member.

[0046] Specifically, align the cylindrical hole below the compressor valve with the positioning piece 120 on the fixing device 100. Since the positioning piece 120 and the cylindrical hole are clearance-matched, the positioning piece 120 can be quickly inserted into the cylindrical hole to fix the compressor valve. At the same time, the upper surface of the workbench 110 is a plane. After the positioning piece 120 is inserted, the entire compressor valve can be placed on the workbench 110 in a balanced manner, which improves the stability of the compressor valve placement and facilitates the subsequent disassembly of the compressor valve.

[0047] It is understandable that the workbench 110 is usually arranged in a rectangular parallelepiped shape, which is convenient for clamping the workbench 110 on the vise, that is, it is convenient for fixing the workbench 110, thereby improving the stability and disassembly efficiency of the compressor valve. At the same time, two positioning members 120 are provided, which can ensure the stability of the compressor valve positioning, prevent the compressor valve from moving during the disassembly process, and thereby improve the disassembly efficiency.

[0048] In a feasible implementation manner, a track 111 is provided on the workbench 110 , and the positioning member 120 can move within the track 111 .

[0049] Among them, by setting the track 111, the positioning member 120 can move in the track 111, so that the distance between the two positioning members 120 can be adjusted. By adjusting the distance between the two positioning members 120, the fixing device 100 can be applied to compressor valves of different models, thereby improving the utilization rate and application range of the fixing device 100. In other words, when disassembling compressor valves of different models, there is no need to replace different fixing devices 100, thereby reducing the maintenance cost of the compressor valve and improving the economy of the fixing device 100.

[0050] It should be noted that the workbench 110 is usually configured to be hollow, and a slot is opened on the upper surface of the workbench 110 , which can serve as a track 111 of the fixing device 100 , so that the positioning member 120 can move back and forth in the slot.

[0051] In a feasible implementation manner, the positioning member 120 includes:

[0052] A positioning rod 121, on which an external thread is provided, and the positioning rod 121 is arranged in the track 111;

[0053] The nut 122 is externally disposed on the positioning rod 121 . The nut 122 is located on the workbench 110 . The nut 122 is used to adjust the height of the positioning rod 121 protruding from the workbench 110 .

[0054] The positioning member 120 includes a positioning rod 121 and a nut 122. The outer surface of the positioning rod 121 is provided with threads, and the nut 122 is sleeved on the outside of the positioning rod 121. By adjusting the position of the nut 122 on the positioning rod 121, the height of the positioning rod 121 outside the workbench 110 can be controlled, and then the distance of the positioning rod 121 extending into the cylindrical hole can be controlled to prevent the positioning rod 121 from being too high and touching the top wall of the cylindrical hole, causing scratches and wear on the compressor valve. It can be understood that the cylindrical hole is sleeved on the nut 122, and the nut 122 is in clearance with the cylindrical hole. A protective cover can be set outside the positioning rod 121 and the nut 122 to prevent the positioning member 120 from causing scratches and wear on the cylindrical hole.

[0055] It should be noted that the setting of the nut 122 has a certain limiting effect on the positioning rod 121. In order to ensure the smooth movement of the positioning rod 121 in the track 111, the positioning rod 121 and the track 111 are usually clearance-fitted. The setting of the nut 122 can shorten the length of the positioning rod 121, that is, the positioning rod 121 does not need to contact the bottom wall of the workbench 110, thereby effectively shortening the length of the positioning rod 121; it can also prevent the positioning rod 121 from falling from the track 111 into the workbench 110 after tilting. Through the mutual cooperation of the positioning rod 121 and the nut 122, the positioning rod 121 can move with the nut 122 in the track 111, which is convenient for positioning different types of compressor valves. At the same time, the nut 122 enables the positioning rod 121 to be vertical, thereby improving the reliability of the positioning rod 121 driving the nut 122 to move.

[0056] In a feasible implementation manner, the fixing device 100 further includes:

[0057] The hand pull rods 130 are disposed on both sides of the workbench 110 in the length direction, and the hand pull rods 130 are fixedly connected to one end of the positioning rod 121 located below the workbench 110 .

[0058] Among them, a pair of hand pull rods 130 are arranged on both sides of the length direction of the workbench 110, and the hand pull rods 130 are fixedly connected to one end of the positioning rod 121, and the end of the positioning rod 121 connected to the hand pull rod 130 is located in the hollow shape of the workbench 110. The height of the positioning rod 121 located outside the workbench 110 can be adjusted by the nut 122, that is, the height of the positioning rod 121 located in the hollow shape can be adjusted, and the hand pull rod 130 can be parallel to the upper surface of the workbench 110 by adjusting the nut 122. In this way, when the hand pull rod 130 pulls the positioning rod 121, the hand pull rod 130 can move smoothly, thereby improving the reliability and stability of the movement of the positioning member 120. It can be understood that the parallelism of the hand pull rod 130 and the workbench 110 means that it is basically parallel, that is, the inclination angle does not exceed 3°.

[0059] It should be noted that the end of the hand pull rod 130 away from the workbench 110 can be set as a ring-shaped hole or a hook shape, which is convenient for the staff to hold and realize the movement of the positioning member 120. It is understandable that the hand pull rod 130 can also be a straight rod shape. When the hand pull rod 130 is a straight rod shape, an anti-slip cover can be set on the end away from the workbench 110 to facilitate the staff to operate and avoid abrasion to the staff's hands.

[0060] In this embodiment, by setting the hand pull rod 130, on the one hand, it is easier to adjust the distance between the two positioning members 120, and on the other hand, it can ensure the stability of the positioning member 120 moving in the track 111, preventing the positioning rod 121 from falling out of the track, thereby ensuring the reliability of the fixing device 100.

[0061] Figure 3 It is a schematic diagram of a fixing device according to another embodiment of the utility model.

[0062] The utility model also provides a compressor valve disassembly fixing device 100, such as Figure 3 As shown, it also includes:

[0063] A pair of fixing plates 140 are disposed at both ends of the workbench 110 in the length direction;

[0064] A telescopic rod 150, one end of which is fixedly connected to the fixing plate 140, and the two telescopic rods 150 are arranged opposite to each other;

[0065] The arc plate 160 is disposed at the other end of the telescopic rod 150 .

[0066] Among them, in order to further improve the stability of the compressor air valve fixation, a fixed plate 140 can be set at both ends of the length direction of the workbench 110, a telescopic rod 150 is set on the fixed plate 140, and an arc plate 160 is set on the end of the telescopic rod 150 away from the fixed plate 140. The arc plates 160 on both sides and the cooperation with the telescopic rod 150 can achieve the clamping of the compressor air valve, thereby improving the reliability of the compressor air valve fixation.

[0067] It should be noted that during installation, the compressor valve is first installed on the positioning member 120 by squeezing the telescopic rods 150 on both sides, and then the telescopic rods 150 are released, and the external arc of the compressor valve is squeezed by the arc plate 160 on the telescopic rod 150 to improve the stability of the compressor valve fixation, thereby improving the disassembly efficiency. Alternatively, one of the telescopic rods 150 can be squeezed on the outside of the compressor valve to gradually move the compressor valve to the center of the workbench 110. At this time, the arc plates 160 on both sides have a clamping force on the compressor valve. The compressor valve is manually moved so that the columnar hole on it is aligned with the positioning member 120 and then released, so that the positioning member 120 and the telescopic rod 150 can double fix the compressor valve, thereby improving the stability of the compressor valve fixation.

[0068] It is understandable that the telescopic rod 150 can be a mechanical structure, or a hydraulic rod or a cylinder. Usually, in order to reduce the manufacturing cost and the maintenance and repair cost, the telescopic rod 150 of the mechanical structure is selected. The uncompressed telescopic rod 150 can make the distance between the two relative arc plates 160 always smaller than the diameter of the compressor valve.

[0069] Figure 4 Schematic diagram of a telescopic rod according to another embodiment of the utility model.

[0070] In a possible implementation, Figure 4 As shown, the telescopic rod 150 includes:

[0071] An outer cylinder 151, one end of the outer cylinder 151 is fixedly connected to the fixing plate 140;

[0072] The inner cylinder 152 is disposed in the outer cylinder 151, at least a portion of the inner cylinder 152 is located outside the outer cylinder 151, and the inner cylinder 152 is connected to the arc plate 160;

[0073] Spring 153 , one end of the spring 153 is fixedly connected to one end of the outer tube 151 away from the fixed plate 140 , and the other end of the spring 153 is connected to one end of the inner tube 152 close to the arc plate 160 .

[0074] The spring 153 is a compression spring, and the arrangement of the spring 153 can realize the extension and retraction of the telescopic rod 150, and realize the pre-tightening force applied by the telescopic rod 150 on the compressor valve. At the same time, through the arrangement of the inner cylinder 152 and the outer cylinder 151, the inner cylinder 152 can move in the outer cylinder 151, thereby realizing the adjustment of the distance between the two relative arc plates 160, and thereby realizing the clamping of compressor valves of different models.

[0075] It can be understood that the spring 153 can be arranged outside the outer cylinder 151 or inside the outer cylinder 151, that is, one end of the spring 153 is fixedly connected to the fixed plate 140, and the other end of the spring 153 is fixedly connected to the inner cylinder 152 located in the outer cylinder 151, so that the telescopic rod 150 can be extended and retracted, that is, the pre-tightening force applied by the telescopic rod 150 to the compressor valve is realized.

[0076] Figure 5 The internal schematic diagram of the telescopic rod according to another embodiment of the utility model

[0077] In a possible implementation, Figure 5 As shown, a slideway 154 is provided inside the outer cylinder 151 , and a slider 155 is provided on the side of the inner cylinder 152 facing the outer cylinder 151 , and the slider 155 is disposed inside the slideway 154 .

[0078] In order to facilitate the smooth sliding of the inner cylinder 152 in the outer cylinder 151, the inner cylinder 152 and the outer cylinder 151 are clearance-matched, so a slideway 154 can be provided in the outer cylinder 151, and a slider 155 can be provided on the outer wall of the inner cylinder 152. Through the cooperation between the slider 155 and the slideway 154, the linearity of the movement of the inner cylinder 152 can be achieved, that is, it can prevent the inner cylinder 152 from rotating or moving in the outer cylinder 151, which affects the working stability of the telescopic rod 150.

[0079] It should be noted that multiple slideways 154 are arranged in the outer cylinder 151, and the multiple slideways 154 are evenly arranged on the inner wall of the outer cylinder 151. The arrangement of multiple slideways 154 can ensure the stability of the movement of the slider 155, thereby ensuring the stability and reliability of the movement of the inner cylinder 152 in the outer cylinder 151. In this embodiment, two slideways 154 can be arranged, and the angle between the two slideways 154 is 180°, that is, the two slideways 154 are arranged opposite to each other. By arranging the two slideways 154, the stability of the movement of the inner cylinder 152 in the outer cylinder 151 can be improved, the manufacturing cost of the fixing device 100 can be reduced, and the preparation efficiency of the fixing device 100 can be improved.

[0080] It is understandable that multiple slideways 154 can also be set outside the inner cylinder 152, and a slider 155 can be set on the outer cylinder 151. The stability and reliability of the movement of the inner cylinder 152 in the outer cylinder 151 are achieved through the cooperation of the slider 155 and the slideway 154, which is also the scope of protection of this application.

[0081] In a feasible implementation manner, an anti-slip pad 170 is provided on a side of the arc plate 160 facing away from the telescopic rod 150 .

[0082] Among them, an anti-slip pad 170 is arranged on the side of the arc plate 160 away from the telescopic rod 150. On the one hand, it can increase the friction between the arc plate 160 and the compressor valve, thereby improving the reliability of clamping a pair of arc plates 160. On the other hand, it can also prevent the arc plate 160 from causing wear on the surface of the compressor valve, thereby ensuring the surface quality of the compressor valve.

[0083] It can be understood that the anti-skid pad 170 is a rubber pad, and a plurality of raised points can be provided on the rubber pad to further increase the friction force, thereby improving the reliability and stability of the arc plate 160 clamping the compressor valve.

[0084] In a feasible implementation manner, the telescopic rod 150 and the arc plate 160 are detachably connected.

[0085] The telescopic rod 150 and the arc plate 160 may be fixedly connected or detachably connected, that is, one end of the inner cylinder 152 located outside the outer cylinder 151 is detachably connected to the arc plate 160. The detachable connection may be a threaded connection or a snap connection, and a bayonet is provided on the inner cylinder 152 or the arc plate 160, and correspondingly, an elastic clamp is provided on the arc plate 160 or the inner cylinder 152 to realize the snap connection between the inner cylinder 152 and the arc plate 160.

[0086] It should be noted that, through the detachable connection of the arc plate 160, the arc plate 160 can be replaced separately, or the arc plate 160 can be removed to facilitate the maintenance of the telescopic rod 150, thereby increasing the service life of the telescopic rod 150 and ensuring the reliability of the use of the telescopic rod 150.

[0087] In a feasible implementation manner, it is characterized in that the material of the fixing device 100 is steel and / or iron.

[0088] Among them, the telescopic rod 150 can be made of steel. Since the telescopic rod 150 needs to move back and forth, the telescopic rod 150 is prepared using a steel pipe, which can increase the service life of the telescopic rod 150 and extend the maintenance and overhaul time of the telescopic rod 150. Other components, such as the workbench 110, the fixed plate 140, the curved plate 160 and the hand pull rod 130 can be made of iron, which is easier to cut and process, thereby reducing the preparation cost of the fixing device 100 while ensuring the strength of the fixing device 100.

[0089] It is understandable that the fixing device 100 may also be made of other materials, as long as they can meet the use strength of the fixing device, without limitation.
