DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Please refer to Figure 1-8 The present invention provides a technical solution: an assembly fixture for a grounding switch of a high-voltage switch cabinet, comprising a connecting component 1, the connecting component 1 comprising a fixedly connected cross arm 11 and a connecting flange 12, an end of the cross arm 11 away from the connecting flange 12 is hinged with an angle-adjustable rotating component 2, at least two clamping components 3 are rotatably mounted on the rotating component 2, and the multiple clamping components 3 are linearly distributed.

[0026] The connecting assembly 1 includes a fixedly connected cross arm 11 and a connecting flange 12, and the rotating assembly 2 includes a rotating seat 21 rotatably connected to the cross arm 11, a connecting plate 23 is fixedly installed on the side of the rotating seat 21 away from the connecting flange 12, and the same telescopic cylinder 22 is hinged between the rotating seat 21 and the cross arm 11.

[0027] Furthermore, by controlling the extension and retraction of the telescopic cylinder 22, the rotating seat 21 can be controlled to rotate within a range of 0° to 90° with the cross arm 11 as the center, and the connecting flange 12 can be fixedly connected to the industrial robot arm.

[0028] Operating handles are also fixedly mounted on both sides of the cross arm 11.

[0029] Furthermore, the position of the device can be adjusted manually by holding two operating handles.

[0030] The clamping assembly 3 includes a mounting frame 31 fixedly connected to the connecting plate 23, a card slot 32 is provided on the mounting frame 31, a clamping claw 33 and a telescopic cylinder 2 34 are rotatably installed in the mounting frame 31, a rotating shaft 1 331 fixedly connected to the mounting frame 31 passes through the clamping claw 33, the rotating shaft 1 331 is rotatably connected to the mounting frame 31, and the output rod of the telescopic cylinder 2 34 is hinged to the clamping claw 33.

[0031] Furthermore, when clamping and fixing the rotating shaft of the grounding switch, the rotating shaft of the grounding switch is first placed in the slot 32, and then the telescopic cylinder 2 34 is controlled to shorten, so that the clamping claw 33 rotates around the rotating shaft 1 331 and approaches the slot 32, thereby clamping and fixing the rotating shaft of the grounding switch through the cooperation between the clamping claw 33 and the slot 32.

[0032] The clamping slot 32 is provided with an arc-shaped portion 1 321 , and the clamping jaw 33 is provided with an arc-shaped portion 2 332 matched with the arc-shaped portion 1 321 .

[0033] Furthermore, by providing the arc portion 1 321 and the arc portion 2 332 , the shape of the rotating shaft of the grounding switch can be more closely matched, the contact area between the slot 32 , the clamping claw 33 and the rotating shaft of the grounding switch is increased, and the clamping stability of the rotating shaft of the grounding switch when the clamping claw 33 cooperates with the slot 32 is improved.

[0034] The mounting frame 31 is provided with a supporting mechanism 35, which includes a supporting block 1 351 rotatably connected to the mounting frame 31, a rotating shaft 2 353 fixedly connected to the mounting frame 31 passes through the supporting block 1 351, the rotating shaft 2 353 is rotatably connected to the mounting frame 31, a supporting block 2 352 is fixedly installed on one side of the supporting block 1 351, two pin holes 2 354 are provided on one side of the supporting block 1 351, the rotating shaft 2 353 is located between the two pin holes 2 354, a latch 36 is detachably installed on one side of the mounting frame 31, the latch 36 passes through the mounting frame 31 and transitionally matches with the inner wall of the corresponding pin hole 2 354.

[0035] Furthermore, when the clamping claw 33 cooperates with the slot 32 to clamp the rotating shaft of the grounding switch, the fixed shaft of the grounding switch can be abutted against the abutment mechanism 35. According to the different distances between the rotating shaft and the fixed shaft of the grounding switch, the user can determine whether to use the abutment block 1 351 to support the fixed shaft of the grounding switch or to use the abutment block 2 352 to support the fixed shaft of the grounding switch. When the positions of the abutment block 1 351 and the abutment block 2 352 need to be swapped, it is only necessary to remove the pin 36 from the corresponding pin hole 2 354, and then manually move the abutment block 1 351 or the abutment block 2 352 to rotate it 180° with the rotating shaft 2 353 as the center, and then insert the pin 36 into the other pin hole 2 354 to fix it.

[0036] A recessed portion 355 is formed on the side of the abutting block 1 351 and the side of the abutting block 2 352 that are away from each other.

[0037] Furthermore, when the slot 32 cooperates with the clamping claw 33 to clamp the rotating shaft of the grounding switch, the fixed shaft of the grounding switch just abuts against any inner recess 355 of the abutting block 1 351 or the abutting block 2 352, and the two sides of the inner recess 355 just abut against the fixed shaft of the grounding switch, thereby improving the stability of the clamping of the grounding switch.

[0038] A locking assembly 4 is installed on one side of the rotating seat 21, and the locking assembly 4 includes a bracket 41 fixedly connected to the rotating seat 21, a groove 42 is provided on the bracket 41, a pin rod 43 is provided in the groove 42, the pin rod 43 passes through the bracket 41 and is slidably connected to the bracket 41, a handle 45 is movably installed on the end of the pin rod 43 away from the connecting plate 23, a spring 44 is slidably sleeved on the pin rod 43, and both ends of the spring 44 are fixedly connected to the pin rod 43 and the bracket 41 respectively, two pin holes 231 are provided on the connecting plate 23, and the connecting assembly 1 is located between the two pin holes 231.

[0039] Furthermore, when it is necessary to rotate the clamping assembly 3 to adjust the upper and lower relationship between the abutting mechanism 35 and the slot 32, the handle 45 can be pulled, and the pin rod 43 can overcome the elastic force of the spring 44 and move out of the pin hole 231 through the handle 45. Then, the entire connecting plate 23 can be rotated 180°, so that the upper and lower relationship between the abutting mechanism 35 and the slot 32 can be adjusted according to actual usage requirements. After the connecting plate 23 is rotated, the handle 45 is released, and the pin rod 43 will be driven into another pin hole 231 under the elastic force of the spring 44 to fix the position of the connecting plate 23.

[0040] Flexible pads are fixedly mounted on the inner concave portion 355 , the first arc portion 321 , and the second arc portion 332 .

[0041] Furthermore, the additional flexible pad can prevent the fixed shaft and the rotating shaft on the grounding switch from loosening and being scratched.

[0042] In this embodiment, when in use, the connecting component 1 is fixedly connected to the industrial robot arm, and the industrial robot arm drives the device to adjust its position. Then, the rotating shaft of the grounding switch is clamped and fixed by the clamping component 3, so that the fixed shaft of the grounding switch is abutted against the clamping component 3, thereby achieving the clamping operation of the grounding switch, and the number of the clamping components 3 is at least two, which improves the stability of the clamped grounding switch. Then, the clamping component 3 is manually controlled to rotate 180°, so that the upper and lower relationship between the rotating shaft and the fixed shaft of the grounding switch changes, and the horizontal and vertical states of the grounding switch are adjusted by controlling the extension and contraction of the telescopic cylinder 22 to adjust the position state of the grounding switch when entering the high-voltage switch cabinet (such as Figure 6-8 As shown in the figure), ensure that the mounting holes on the grounding switch can be aligned with the mounting holes in the switch cabinet, and then fix the grounding switch to the switch cabinet with fasteners.
