Description

Technical Field

[0001] The utility model relates to the technical field of installation fixtures, in particular to a nut installation auxiliary fixture. Background Art

[0002] A nut is a cap that is screwed together with a bolt or screw to act as a fastener. In machining, nuts are commonly used workpieces and usually require workers to manually select and install them to the required position.

[0003] When installing existing nuts, pliers and wrenches are usually used as clamps to assist in the installation. When encountering the installation of nuts and bolts in some special positions, such as when the nut installation position is relatively narrow, traditional pliers and wrenches cannot reach in to assist in the installation of the nut. Therefore, a nut installation auxiliary clamp is proposed. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A nut installation auxiliary clamp includes a mounting rod and a control box. The mounting rod is axially penetrated by two straight rods that are rotatably connected. The two straight rods are symmetrically distributed, and the lower ends of the two straight rods are connected to clips. The control box is installed on the top of the mounting rod and is used to control the rotation of the clips on the two straight rods to clamp the nuts.

[0007] Preferably, the two end walls of the control box are commonly connected with a sliding rod, a slider is slidably connected to the sliding rod, the upper ends of the two straight rods extend into the control box, the upper end of each straight rod is coaxially connected to a gear, the side of the slider close to the straight rod is connected to a straight rack, the straight rack and the two gears are meshed with each other, the outer wall of the control box is connected to handle 1, and a sliding groove is provided on the box wall of the control box close to handle 1, and handle 2 is slidably connected in the sliding groove, and handle 2 is connected to the slider.

[0008] Preferably, a spring is sleeved on the slide bar, and two ends of the spring are respectively connected to the slider and the inner wall of the control box.

[0009] Preferably, the angles of the clips on the two straight rods are distributed symmetrically around the center.

[0010] Preferably, anti-slip grooves are provided on the clamping surface of each of the clamping pieces.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] The clamp provided by the utility model solves the problem that when the nut installation position is in a narrow space, the traditional clamp is difficult to clamp and cannot assist in the installation. Moreover, when the clamp assists in the installation of the nut, the entire clamping and loosening operation is simple and quick, thereby improving the installation efficiency of the nut.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-3 As shown, a nut installation auxiliary clamp includes a mounting rod 1 and a control box 2, the mounting rod 1 has two straight rods 11 rotatably connected in the axial direction, the two straight rods 11 are symmetrically distributed, and the lower ends of the two straight rods 11 are connected to clips 12, the control box 2 is installed on the top of the mounting rod 1 and is used to control the rotation of the clips 12 on the two straight rods 11 to clamp the nut, and the angles of the clips 12 on the two straight rods 11 are centrally symmetrically distributed.

[0019] In this embodiment, the two end walls of the control box 2 are commonly connected with a slide bar 21, and a slider 22 is slidably connected to the slide bar 21. The upper ends of the two straight rods 11 extend into the control box 2, and the upper end of each straight rod 11 is coaxially connected with a gear 24. The side of the slider 22 close to the straight rod 11 is connected to a straight rack 23, and the straight rack 23 is engaged with the two gears 24. The outer wall of the control box 2 is connected to a handle 1 26, and the box wall of the control box 2 close to the handle 1 26 is provided with a slide groove 28, and a handle 2 27 is slidably connected in the slide groove 28, and the handle 2 27 is connected to the slide bar 22.

[0020] In this embodiment, a spring 25 is sleeved on the slide bar 21 , and two ends of the spring 25 are connected to the slider 22 and the inner wall of the control box 2 respectively.

[0021] In this embodiment, anti-slip grooves 121 are provided on the clamping surface of each of the clips 12 to increase the friction between the clips 12 and the nut and reduce the occurrence of slippage.

[0022] Working process and principle:

[0023] When in use, one hand grasps handle 1 26 and handle 2 27 at the same time, so that the lower end of the mounting rod 1 is close to the nut, so that the nut is located between the two straight rods 11, and then holds handle 27 close to handle 1 26. The slider 22 in the control box 2 will slide along with the handle 27, and the two straight rods 11 will rotate in the same direction and speed through the meshing transmission of the straight rack 23 and the gear 24. At this time, the two clips 12 rotate to clamp the nut, and then move the clamp and the nut to the mounting hole, and tighten the bolt from the other side to complete the connection of the bolt and nut. After the nut is installed, loosen handle 27. Under the action of the spring 25, the clip 12 rotates in the opposite direction to loosen, so that the clamp can be quickly separated from the nut.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
