Detailed Description
In order to better understand the technical solution of the present invention, the following detailed description is made by specific embodiments with reference to the accompanying drawings:
referring to fig. 1, the auxiliary clamping tool for a washer and a nut of the present invention includes an auxiliary clamp 100 for clamping a washer and a nut, a telescopic rod 200, and a base 300.
Referring to fig. 2, the auxiliary clamp 100 includes a telescopic rod mounting cylinder 110 and a nut receiving cylinder 120 coaxially disposed, and a pair of clip structures 130 disposed at both sides of the nut receiving cylinder 120.
The telescopic rod mounting cylinder 110 is used for mounting the telescopic rod 200, and both the inner diameter and the outer diameter of the telescopic rod are smaller than those of the nut accommodating cylinder 120. To ensure the connection strength of the extension rod 200, the inner cavity of the extension rod mounting cylinder 110 can extend into the inner cavity of the nut accommodating cylinder 120. An annular magnet 121 is fixed at the end opening part of the inner side of the cavity of the nut accommodating cylinder 120 and used for sucking the nut and the gasket, and the magnet 121 is a neodymium iron boron magnet with the diameter of 20 × 10 × 3 mm. The surface of the magnet 121 is provided with a friction increasing structure, in this embodiment, in order to reduce the complexity of the structure, the friction increasing structure adopts sand paper attached to the surface of the magnet 121, and other forms of friction increasing structures can be added to the magnet 121, so as to increase the friction between the magnet 121 and the adsorbed nut, thereby facilitating the rotation of the nut.
The clip structure 130 includes a connecting section 131 and a clamping section 132, the connecting section 131 is at an angle of 20 ° to 30 °, preferably 24.53 ° in this embodiment, with respect to the axial direction of the telescopic rod mounting cylinder and the nut receiving cylinder, and the angle does not affect the magnet suction nut and the washer. When the hand applies pressure to the clip structure 130, the elasticity of the material is used to make the clamp section 132 generate a component force perpendicular to the axial direction, so as to clamp the edge of the nut and adjust the position of the nut. The end of the clamp segment 132 does not exceed the projection range of the cross section of the nut accommodating barrel 120, and interference caused when the magnet 121 absorbs and fixes the nut and the gasket is avoided.
Referring to fig. 3, the telescopic rod 200 is a spring rod structure, the middle of which is provided with a spring structure 210, and the spring 210 is a compression spring of 0.6 × 10 × 45mm and can be fixed at a slightly protruding part in the middle of the telescopic rod, and the telescopic rod has a telescopic capability by utilizing the inherent characteristic that the compression spring deforms under the action of external force and recovers to the original shape after the external force is removed. The length of the telescopic rod is greater than that of the auxiliary clamp, and the bottom end 220 of the telescopic rod is inserted in the telescopic rod mounting cylinder 110. The function of the telescopic rod 200 is to provide guidance for the magnet 121 when it sucks the washer and the nut in sequence, so that the washer and the nut are overlapped orderly and regularly. The top of telescopic link 200 is for being used for being convenient for to penetrate and the conical platform structure 230 of spacing packing ring and nut, and the external diameter of the telescopic link linkage segment 240 of conical platform structure 230 top is less than the internal diameter of annular magnetite 121, avoids after magnetite 121 successfully adsorbs the nut, and telescopic link linkage segment 230 and the internal thread of nut produce the friction, hinder telescopic link 200 outwards to pop out.
Referring to fig. 4, the base 300 is a tubular structure, and is sleeved outside the telescopic rod mounting tube 110, and functions to effectively extend the telescopic rod mounting tube 110, so that sufficient supporting force can be formed after the base is fully contacted with a palm, so that an operator can conveniently press down and rotate the auxiliary clamping tool, and can be connected with other tools through the base 300, and meanwhile, the structural strength of the telescopic rod mounting tube 110 can be enhanced. The port of the base 300 connected to the telescopic rod mounting tube 110 is provided with an annular platform structure 310, which is used for picking up the auxiliary clamping tool by the operator.
The utility model is suitable for an adopt insulating gloves operation method to untie and fasten the work of pile head nut in carrying out the live working operation, can reliably adsorb the nut in proper order and spiral the corresponding screw rod with the packing ring in proper order.
When untiing the nut, at first loosen the nut soon to screw rod port portion, then aim at the nut hole with the telescopic link end, push down the base, make the telescopic link contract under spring structure's effect and hold a section of thick bamboo inside to the nut, through the adsorption affinity and the magnetic force transmission of magnetite, concatenate nut and packing ring on the telescopic link in proper order, treat the telescopic link back that resets, loosen the nut and accomplish the dismantlement of packing ring and nut.
When the nut is untied in screwing, put packing ring and nut in proper order on work platform, aim at the part hole with the telescopic link end, push down the base, make the telescopic link contract to the nut under the effect of spring structure and hold a section of thick bamboo inside, through the adsorption affinity and the magnetic force transmission of magnetite, concatenate nut and packing ring on the telescopic link in proper order. After the telescopic rod is reset, the telescopic rod is aligned to the screw rod and then pressed down again, and the telescopic rod can be smoothly sleeved outside the screw rod due to the fact that the aperture of the gasket is larger than the diameter of the screw rod in the pressing down process. And continuously pressing downwards, when the screw cap collides with one end of the screw rod, rotating the auxiliary clamping tool, and utilizing the friction force generated by the abrasive paper on the surface of the magnet to enable the screw cap to have certain rotating power so as to offset the adsorption force of the magnet, so that the screw cap is screwed into the screw rod. And when nut and screw rod were not vertical alignment, two direct screw threads can not the one-to-one, and the relative angle of screw rod and nut was not enough corrected to the frictional force that simply relies on the magnetite surface, can press the clamping piece structure at this moment and press from both sides the nut and get and right, then utilize magnetite surface frictional force to twist in the screw rod. It should be noted that the utility model discloses an auxiliary clamping tool can not screw up the nut completely, twists the screw rod back with plain washer, elastic washer and nut when utilizing auxiliary clamping tool, need adopt insulating spanner again to carry out the fastening of nut, accomplishes the overlap joint of lead wire. The flat washer, the elastic washer and the nut are all strung on the telescopic rod and firmly adsorbed on the magnet in the whole operation process, and the falling probability of the thin and small parts is greatly reduced.
It will be appreciated by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as limitations of the present invention, and that changes and modifications to the above described embodiments will fall within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
