Description

A positioning pin device with quick clamping function

technical field

The utility model relates to a positioning pin device with a fast clamping function, which is used for the positioning of components in the product assembly process and belongs to the technical field of assembly and manufacturing.

Background technique

The structure of the positioning pin used for hole positioning is usually just a simple cylindrical structure with a diameter and a matching relationship with the positioning hole. This structure makes it impossible to clamp and fix the positioned part immediately when the positioning pin is inserted into the positioning hole for assembly. It also needs other auxiliary tools (such as bow clips, etc.) to be used in conjunction to realize the clamping function.

Therefore, the current locating pins can only achieve hole positioning, but cannot achieve clamping at the same time, and the assembly efficiency is low; when using auxiliary tools, issues such as clamping space need to be considered, which brings cumbersome and inconvenient operations. In addition, other positioning parts such as manual or pneumatic pull codes are also used in product assembly at home and abroad. Although the rapid positioning of the positioned parts can be achieved, the diameter of the pull code and the diameter of the positioning hole are quite different, and the positioning accuracy is poor. The pull code structure itself is relatively complicated, and the manufacturing cost is high.

When clamping is required, the two sides of the opening end of the clamping piece are respectively inserted into the cylinder of the positioning pin body in the two grooves of the segment.

Wherein, the positioning pin device further includes an adjusting gasket, which is arranged between the component to be connected and the positioning pin handle, and is sleeved on the threaded section.

Wherein, the end of the cylindrical section not connected with the threaded section has a chamfer.

Wherein, the positioning pin handle also has a handle.

Wherein, the clamping piece has an operating portion connected to the clamping portion, and the axis of the operating portion forms an included angle of 10-60° with the plane where the opening end is located.

Wherein, the axis of the operating part forms an included angle of 20° with the plane where the clamping part is located.

Wherein, the chamfer is 30°.

Wherein, the opening width L of the opening end and the distance L' between the two axially symmetrical groove bottoms on the positioning pin body satisfy the following relationship: L-L' is 0.5-1.5 mm.

The beneficial effects of the utility model compared with the prior art are:

(1) When using the positioning pin device disclosed in the utility model for positioning, first insert the positioning pin body into the positioning hole of the positioned part, insert the opening of the clamping piece into the slot on the positioning pin body, and rotate the positioning pin handle to perform positioning. Fast positioning and clamping are completed at the same time, and the positioning and clamping speed is fast.

(2) The clamping piece has a bending structure, which avoids the problem of inconvenient operation of the clamping piece when the surface size of the positioned part is too large, and can facilitate quick manual operation.

(3) When disassembling, turn the handle of the positioning pin counterclockwise to release the clamped part from the clamped state, remove the clamping piece, pull out the handle of the positioning pin and the body of the positioning pin together to complete quick disassembly, and the disassembly speed is fast.

(4) The locating pin device adopts a threaded structure, which can adjust the locating length, and can adapt to the positioning of the positioned parts with different depths.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

The positioning pin device includes: a positioning pin body 1, a positioning pin handle 2, an adjusting gasket 3, and a clamping piece 4.

As shown in Figures 1 and 2, one end of the positioning pin body 1 is a cylindrical structure with a diameter consistent with the diameter of the positioned hole; the end is chamfered at 30°; the cylindrical surface has two symmetrical slot structures, and the bottom surface of the slot is The spacing matches the opening size of the clamping piece, and the clamping piece 4 can be inserted into the slot; the other end of the positioning pin body 1 is an external thread structure, which is threadedly connected with the internal thread of the positioning pin handle 2. The locating pin body 1 and the locating pin handle 2 are integrally connected by thread.

As shown in FIG. 3 , the positioning pin handle 2 includes a handle body 5 and a handle 6 . The handle body 5 is a cylindrical hollow structure with an internal thread whose size matches the external thread of the positioning pin body 1 ; one end has a through hole structure to match the handle 6 . The handle 6 is a cylindrical structure, which matches with the through hole at one end of the handle body 5 and is inserted into the through hole to form an integrated structure.

The adjusting gasket 3 is a gasket used in cooperation with the external thread of the positioning pin body.

The clamping piece 4 is a sheet metal structure, and one end has an opening structure. Referring to FIG. The distance L' between the bottoms of the two axially symmetrical grooves satisfies the following relationship: L-L' is 0.5-1.5 mm. The other end is used for hand-held operation. It is a bent structure and forms an angle of 20° with the plane of the open end.

When using, include the following steps:

1) Connect the positioning pin body 1 and the positioning pin handle 2 with threads;

2) Insert the positioning pin body 1 into the positioning hole of the component to be positioned.

3) Check whether the slot on the positioning pin body 1 is completely exposed to the surface of the positioned part. If not, loosen the positioning pin body 1 and the positioning pin handle 2 and insert them into the positioning hole again until the slot on the positioning pin body 1 is completely exposed.

4) Holding the clamping piece 4, insert the opening of the clamping piece 4 into the slot on the positioning pin body.

5) Rotate the handle 2 of the positioning pin to tighten it, and realize fast positioning and clamping at the same time. If the groove of the positioning pin body 1 exposes too much surface of the positioned part, and the positioned part is not clamped after the positioning pin handle 2 is tightened, an adjusting gasket 3 of appropriate thickness can be added between the positioning pin handle 2 and the positioned part to ensure Clamp securely.

6) When disassembling, rotate the positioning pin handle 2 counterclockwise to make the clamped part out of the clamped state. Disassemble the clamping piece 4, and pull out the positioning pin handle 2 and the positioning pin body 1 together to realize quick disassembly.
