Embodiment 1

[0016] Such as figure 1 The fastener auxiliary processing pliers shown include a first pliers body 4 and a second pliers body 5 arranged crosswise, a turntable 6 is arranged in the middle of the first pliers body 4 and the second pliers body 5, and the first pliers body The turntables 6 of the body 4 and the second pliers 5 overlap each other and are connected by a rotating pin 7 to form a rotating structure in which the first pliers 4 and the second pliers 5 rotate around the rotating pin 7. The first pliers 4 and the parts of the second pliers body 5 located at both ends of the turntable 6 are the clamping end and the handle end respectively, and the inner sides of the clamping ends of the first pliers body 4 and the second pliers body 5 are respectively provided with nut clamping blocks 1 And the bolt clamping block 2, the cross section of the nut clamping block 1 matches the shape of the nut part, and the opposite end faces of the bolt clamping block 2 of the first clamp ...

Embodiment 2

[0020] This embodiment adds the following structure on the basis of Embodiment 1: the inner side of the clamping end of the first clamp body 4 is also provided with an auxiliary guide plate 3 at the side end of the bolt clamping block 2, and the auxiliary guide plate 3 is perpendicular to Set on the inside of the clamping end.

[0021] In actual operation, when the bolt clamping block 2 is used to clamp fasteners such as bolts, screws or screws, the direction of the fasteners is limited under the action of the auxiliary guide plate 3, so as to ensure that the threads of the fasteners are aligned with the bolt clamps. The threads of the holding block 2 are fully matched, and can also maintain the clamping direction, so that the direction of the fastener clamped each time is constant, ensuring the stability and orientation of the clamping, and facilitating subsequent processing operations.

Embodiment 3

[0023] This embodiment is further optimized on the basis of embodiment 1 or embodiment 2, specifically: the end surface of the nut clamping block 1 located inside the clamping end is provided with criss-cross anti-slip lines.

[0024] In this embodiment, in order to further strengthen the clamping strength of the nut clamping block 1 to the nut and prevent the nut from falling during operation, criss-cross anti-slip lines are specially arranged on the end surface of the nut clamping block 1 located inside the clamping end to strengthen the nut clamping block 1. The clamping effect of the nut is improved, and the clamping is more stable.

Abstract

The invention discloses a pair of auxiliary machining tongs for a fastener. The pair of auxiliary machining tongs for the fastener comprises a first tongs body and a second tongs body, wherein the first tongs body and the second tongs body intersect with each other. The middle portion of the first tongs body and the middle portion of the second tongs portion are respectively provided with a rotary disk. The rotary disk of the first tongs body and the rotary disk of the second tongs body overlap each other and are connected through a rotary pin, so that the rotation structure that the first tongs body and the second tongs body rotate with the rotary pin as the axis is formed. The portions, located at the two ends of the corresponding rotary disk, of the first tongs body are a clamping end and a handle end respectively. The portions, located at the two ends of the corresponding rotary disk, of the second tongs body are a clamping end and a handle end respectively. The inner side of the clamping end of the first tongs body and the inner side of the clamping end of the second tongs body are respectively provided with a nut clamping block and a bolt clamping block, wherein the nut clamping block and the bolt clamping block of the first tongs body are opposite to the nut clamping block and the bolt clamping block of the second tongs body respectively. The cross section of each nut clamping block is matched with the shape of a nut portion. The opposite end faces of the bolt clamping blocks of the first tongs body and the second tongs body are arc-shaped faces. Threads are arranged in the arc-shaped faces. According to the pair of auxiliary machining tongs for the fastener, the structure is simple, the fastener can be well clamped and fixed, the stability is high, the fastener can be clamped according to the direction, manual adjustment of the direction of the fastener is not needed, and machining is facilitated.

Description

technical field [0001] The invention relates to a fastener processing auxiliary tool, which belongs to the field of mechanical processing, and more specifically relates to a fastener auxiliary processing pliers. Background technique [0002] When processing fasteners commonly used in machinery, such as nuts, bolts or screws, etc., some auxiliary tools are often needed for auxiliary processing. Auxiliary pliers are used for clamping to facilitate pick-and-place, processing and stabilizing fasteners, and at the same time, workers are prevented from being scalded or corroded by processing fluids; the existing auxiliary pliers are just ordinary pliers. Due to the clamping force of the pliers, the force cannot be firmly clamped, and it is easy to drop. At the same time, the fastener cannot be clamped in the direction required for processing. The clamped fastener is not oriented so that the fastener is in the It is also necessary to manually adjust the position of the fastener du...
