Utility model content

The utility model aims to solve the problem that problems of the prior art, and the utility model provides the positioning that can be stretched Pin can solve the problems, such as to cause panel damage and positioning pin rapid wear.

A kind of flexible positioning pin, including：Support shaft, be placed on support shaft upper fixing element, between fixing piece and support shaft Locating piece, the fixing piece further includes the first elastic buffer, and first elastic buffer is placed in support shaft and position Between fixing piece and locating piece.

Preferably, first elastic buffer is spring.

Preferably, the locating piece further includes cushion, and the cushion set is on the positioning element.

Preferably, the second elastic buffer is equipped between the support shaft and locating piece, the second elastic buffer is sleeved on branch Support on axis.

Preferably, second elastic buffer is spring.

The utility model provides a kind of positioning pin that can be stretched, which can carry out panel by locating piece Positioning, and when cutting machine is to material clamp panel, even if there is intermediate plate angle, there are one with cycle table-surface level Fixed error problem, panel slightly lifting, the first elastic buffer also can give locating piece certain displacement space so that panel It will not be produced relative sliding between locating piece, plate contact position will not be caused to crack, broken so as to avoid panel The wear problem of piece and positioning pin surface.

Embodiment

Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology Modification of the personnel to the various equivalent forms of the utility model falls within the application appended claims limited range.

Embodiment 1：

The first embodiment of the utility model is illustrated in figure 4, present embodiments provides a kind of positioning pin that can be stretched, Including：Support shaft 1, be placed on 1 upper fixing element 3 of support shaft and the locating piece 2 between fixing piece 3 and support shaft 1, fixed Part 3 further includes the first elastic buffer 4, and the first elastic buffer 4 is placed in support shaft 1, and the first elastic buffer 4 is positioned at fixation Between part 3 and locating piece 2, the first elastic buffer 4 is spring.

In the present embodiment, as shown in Figure 5 and Figure 6, the locating piece 2 of positioning pin can be positioned with counter plate 5, the first bullet Property buffer 4 can carry out providing the space that moves up of locating piece 2 when panel 5 positions in positioning pin, in cutting machine to material When clamp panel 5, since to material clip height and cycle table-surface level, there are certain error, the meeting of panel 5 is somewhat Offset, the surplus for the certain movement that locating piece 2 can be given by the first elastic buffer 4 so that panel 5 and locating piece 2 it Between be not in opposite sliding friction, the contact point between locating piece 2 and panel 5 is fixed, will not cause locating piece 2 Abrasion, will not equally cause the fragmentation of panel 5.

Embodiment 2：

The second embodiment of the utility model is illustrated in figure 7, present embodiments provides a kind of positioning pin that can be stretched, Including：Support shaft 1, be placed on 1 upper fixing element 3 of support shaft and the locating piece 2 between fixing piece 3 and support shaft 1, fixed Part 3 includes the first elastic buffer 4, and the first elastic buffer 4 is placed in support shaft 1, and the first elastic buffer 4 is located at fixing piece Between 3 and locating piece 2, the second elastic buffer 7 is equipped between support shaft 1 and locating piece 2, the second elastic buffer 7 is sleeved on branch Support on axis 1, the first elastic buffer 4 and the second elastic buffer 7 are spring.

The embodiment not only provides the upward movement of locating piece 2 compared to for embodiment by the first elastic buffer 4 Space, also provides the downward mobile space of locating piece 2 by the second elastic buffer 7, can prevent from giving material clamp face Vibrated when plate 5, cause the opposite slip between panel 5 and locating piece 2.
