Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an auxiliary tool for assembling an automobile screw.
Background
The part is very many in the automobile manufacture manufacturing process, generally adopts bolted connection when two adjacent pieces to satisfy the intensity requirement, but because the shape is different between the automobile parts, sometimes has the problem of interference when the construction bolt, for example: when two adjacent parts are installed, a stud is generally used to penetrate through a preformed hole of the two parts, then a nut is used to be connected to the tail end of the stud, the nut needs to be kept still when screwing, the stud is rotated, or the stud and the nut are kept still, the stud and the nut are rotated in the patent document, the stud and the nut need to be kept still, the upper edge of an upper end part protrudes outwards when screwing, a traditional plate-shaped spanner cannot clamp and fix the nut, and the stud and the nut move in the same direction when screwing is caused.
Disclosure of Invention
The utility model aims to provide an auxiliary tool for assembling a screw rod of an automobile, aiming at the problems and the defects in the background technology.
Appurtenance is used in automobile screw assembly, the installation structure comprises a sleeve pipe, the sleeve pipe head end be equipped with and revolve wrong groove, revolve wrong groove and be used for fixing stud, the sleeve pipe is kept away from to revolve wrong groove side and is equipped with the polygon slot, the inserted bar of connecting rod head end is pegged graft inside the polygon slot, the connecting rod middle part is equipped with the double-layered groove that runs through, bracing piece head end sleeve pipe hinge shaft articulates inside double-layered inslot, the bracing piece end links firmly with the screw rod, the outside threaded connection of screw rod has the handle.
The utility model has the beneficial effects that:
1. the utility model has simple structure and convenient use, and the whole material is made of nickel-titanium shape memory alloy material, and the nickel-titanium shape memory alloy material is heated after being deformed, so that the nickel-titanium shape memory alloy material can be recovered to the original shape for continuous use.
2. The sleeve pipe and the connecting rod are of an inserting structure, and the sleeve pipes with different calibers can be replaced according to process requirements.
3. The length of the grip can be adjusted according to the condition, so that the grip is longer and more labor-saving, and the annular limiting baffle can prevent the worker from sliding the grip axially along the grip when using the tool.
4. Be connected for rotating between connecting rod and the bracing piece, can solve traditional straight plate spanner and have the problem of unable centre gripping nut and double-screw bolt under the interference condition.

Detailed Description
Referring to the attached drawings, the auxiliary tool for assembling the automobile screw comprises a sleeve 1, wherein a screwing groove 2 is formed in the head end of the sleeve 1, the screwing groove 2 is used for fixing a double-screw bolt, a polygonal slot 3 is formed in the side, away from the screwing groove 2, of the sleeve 1, an inserting rod 5 at the head end of a connecting rod 4 is inserted into the polygonal slot 3 in an inserting mode, a penetrating clamping groove 5 is formed in the middle of the connecting rod 4, a sleeve hinge shaft at the head end of a supporting rod 6 is hinged to the clamping groove 5, the tail end of the supporting rod 6 is fixedly connected with a screw 7, and a handle 8 is connected to the outer portion of the screw 7 in a threaded mode.
Furthermore, the handle 8 is a tubular structure with an opening at one end, and an annular limiting baffle 9 is arranged on the outer wall of the tail end of the handle 8.
Furthermore, the outer edge of the screwing groove 2 of the sleeve 1 is provided with a chamfer.
Furthermore, the sleeve 1, the connecting rod 4, the inserted link 5, the support rod 6, the screw 7, the handle 8 and the annular limit baffle 9 are all made of nickel-titanium shape memory alloy materials.
Furthermore, a plurality of auxiliary slots 10 are circumferentially arranged on the polygonal slots 3 of the sleeve 1, and a plurality of auxiliary insertion rods 11 capable of being inserted into the auxiliary slots 10 are arranged on the connecting rod 4.
The working principle and the using process of the utility model are as follows:
when the tool is used, the angle between the connecting rod 4 and the supporting rod 6 is adjusted, the head end of the sleeve 1 is screwed with the screw groove 2 to be matched with the nut without interference, after adjustment, the screwed groove 2 is matched with the nut, a worker holds the handle 8 with the left hand, the nut is limited at the moment, the worker screws the stud by using a wrench with the right hand, so that the two parts are fixed together, if a large torque is required to be applied to the stud, the length of the handle 8 can be adjusted according to the situation, the handle 8 is lengthened and is more labor-saving, the annular limiting baffle plate 9 is used for preventing the worker from axially sliding out from the handle 8 when using the tool, the whole material is made of a nickel-titanium shape memory alloy material, the temperature of the whole material is raised after deformation is generated, and the original shape of the whole material can be recovered for continuous use. The sleeve 1 and the connecting rod 4 are in an inserting structure, and the sleeve 1 with different calibers can be replaced according to process requirements.
