Description

Technical Field

[0001] The utility model belongs to the technical field of GIS housing processing, and particularly relates to a fixture for GIS housing processing. Background Technique

[0002] The GIS (Gas Insulated Switchgear) housing is a key component of high-voltage electrical equipment. Its manufacturing precision and processing quality are crucial for the overall performance of the equipment. In order to meet the requirements of high precision, complex shape and stability during the processing of GIS housings.

[0003] When processing the GIS housing, a fixture is required for assistance, and the fixture plays a crucial role in the processing. If there is no fixture assistance during the housing processing, the housing will shift during processing, resulting in difficulty in achieving the design requirements for processing precision, and the production efficiency will also decrease significantly. It is impossible to ensure that the processed housing has accurate dimensions and regular shapes. For this reason, we have proposed a fixture for GIS housing processing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixture for GIS housing processing. By setting a clamping component, specifically, turning the handle of the screw push rod clockwise with force, this action causes the screw push rod to continue to push forward, and through a series of complex mechanical linkages, the clamping block is activated, and the clamping block tightly clamps the housing. As we continuously apply pressure, the clamping block clamps the housing tighter and tighter until it is completely fixed, ensuring the stability of the housing during the processing, greatly improving the production efficiency, and also enhancing the processing quality. It solves the problems that when processing the existing housing without fixture assistance, the housing will shift during processing, resulting in difficulty in achieving the design requirements for processing precision, and the production efficiency will also decrease significantly, and it is impossible to ensure that the processed housing has accurate dimensions and regular shapes.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 As shown, the present invention is a fixture for processing a GIS housing, including a support base 1 and a first motor 2. The back of the first motor 2 is fixedly connected to the front of the support base 1;

[0028] A clamping assembly 11 is arranged above the support base 1. The clamping assembly 11 includes a limit cover 111. The bottom of the limit cover 111 is fixedly connected to a chassis 112. The inner side of the chassis 112 is rotatably connected to a limit disk 113. The bottom of the limit disk 113 is fixedly connected to a first rotating shaft 116. The bottom of the first rotating shaft 116 is rotatably connected to the inner side of the bottom of the chassis 112. Three chutes 133 are provided on the surface of the limit disk 113. A clamping block 131 is arranged above the limit disk 113. The bottom of the clamping block 131 is fixedly connected to a first limit block 132.

The bottom of the limit rod 134 is fixedly connected to a limit piece 135. In the present invention, by setting the clamping assembly 11, specifically, when the handle of the screw push rod 114 is turned clockwise with force, this action causes the screw push rod 114 to continue to push forward, and through a series of complex mechanical linkages, the clamping block 131 is activated, and the clamping block 131 tightly clamps the housing 4. As we continuously apply pressure, the clamping block 131 clamps the housing 4 tighter and tighter until it is completely fixed, ensuring the stability of the housing during the processing, greatly improving the production efficiency, and also improving the processing quality.

[0029] A push block 115 is fixedly connected to the left side of the chassis 112. A fixed arm 151 is arranged on the front of the push block 115. The right side of the fixed arm 151 is fixedly connected to the left side of the chassis 112. A screw push rod 114 is fixedly connected to the inside of the left side of the fixed arm 151.

[0030] A deflection assembly 12 is arranged below the clamping assembly 11. The deflection assembly 12 includes two racks 121. A support frame is arranged on the left side of the rack 121. The bottom of the support frame is fixedly connected to the top of the support base 1. A second rotating shaft 221 is rotatably connected inside the support frame. A second gear 122 is fixedly connected to the front and back of the second rotating shaft 221. In the present utility model, by arranging the deflection assembly 12, specifically, the second motor 3 is started to drive the right-side first gear 31 to rotate. The right-side first gear 31 drives the left-side first gear 31 to rotate. The left-side first gear 31 drives the rotation of the round shaft. The rotation of the round shaft finally transmits the force to the chassis 112, causing the chassis 112 to start rotating. The rotation speed of the chassis 112 is appropriate, making the angle adjustment of the chassis 112 more flexible and the processing more convenient.

[0031] The output end of the back of the first motor 2 is fixedly connected to the front of the second gear 122 located in the front. A round shaft is rotatably connected to the opposite sides of the two racks 121. The corresponding sides of the two round shafts are fixedly connected to the bottom of the chassis 112.

[0032] Two first gears 31 are arranged on the top of the rack 121 located in the front. A second motor 3 is fixedly connected to the right side of the top of the rack 121 located in the front. The output end of the front of the second motor 3 is fixedly connected to the back of the right-side first gear 31.

[0033] The left side of the right-side first gear 31 is meshed and connected to the left-side first gear 31. The back of the left-side first gear 31 is fixedly connected to the front of the round shaft located in the front.

[0034] The right side of the second gear 122 is meshed and connected to the left side of the rack 121. The outer surface of the rack 121 is slidably connected to the inside of the support base 1. A second limiting block 211 is fixedly connected to the right side of the rack 121. The outer surface of the second limiting block 211 is slidably connected to the inside of the support base 1.

[0035] A specific application of this embodiment is as follows: gently turn the handle of the screw push rod 114 counterclockwise, and the internal mechanism of the screw push rod 114 starts to operate. Its output end receives a forward driving force, driving the output end of the screw push rod 114 to rotate flexibly within the limit ring 141 and tightly adhere to the inner wall of the limit ring. At the same time, the hinge ring 142 closely connected to the output end of the screw push rod 114 also starts to move. The hinge ring 142 is connected to the inside of the push block 115 through a pin shaft. When the screw push rod 114 pushes it, it smoothly slides along the pin shaft inside the push block 115, causing the push block 115 to start moving forward, and then driving the connected limit disk 113 to rotate clockwise. The rotation of the limit disk 113 triggers another series of mechanical linkages. It drives the limit rod 134 inside the chute 133 to start rotating and slowly move outward along the preset path of the chute 133. The limit rod 134 drives the first limit block 132 to slide steadily outward within the groove of the limit cover 111. Next, we steadily place the housing 4 above the limit cover 111, and then turn the handle of the screw push rod 114 clockwise forcefully again. This action causes the screw push rod 114 to continue to push forward and, through a series of mechanical linkages, drives the clamping block 131. The clamping block 131 tightly clamps the housing 4. As we continuously apply pressure, the clamping block 131 clamps the housing 4 tighter and tighter until it is completely fixed. At this time, we can operate other parts of this device according to actual needs. Start the first motor 2, and its operation drives the rotation of the second gear 122. The second gear 122 drives the connected rack 121 to slowly rise. The rise of the rack 121 causes the chassis 112 to start moving upward. When the chassis 112 moves to the height we expect, we operate again. Start the second motor 3 to drive the right-side first gear 31 to rotate. The right-side first gear 31 drives the left-side first gear 31 to rotate. The left-side first gear 31 drives the rotation of the round shaft, and the rotation of the round shaft finally transmits the force to the chassis 112, causing the chassis 112 to start rotating. The rotation speed of the chassis 112 is appropriate and ensures its stability.
