Embodiment
For the ease of the understanding of those skilled in the art, further is made to the utility model with reference to embodiment and accompanying drawing
Explanation, the content that embodiment is referred to not to it is of the present utility model limit.The utility model is carried out below in conjunction with accompanying drawing
Detailed description.
A kind of pneumatic spring locking fixture provided by the utility model, is clamped for being fixedly mounted on support panel 1
Product, includes the two jack-up cylinders 2 and the jig main body 3 located at the top of support panel 1 for being arranged at the lower section of support panel 1,
Wherein described jig main body 3 can use the modes such as bolt or compression cylinder to be fixed on support panel 1.The support panel
The circular hole that two piston rods for jack-up cylinder 2 rise is offered on 1, being internally provided with for the jig main body 3 can be living up and down
Dynamic elastic stretching structure, the compact heap 4 being connected with elastic stretching structure, the bullet are provided with the upper end of jig main body 3
The bottom of property stretching structure faces piston rod, and the jack-up cylinder 2 the jack-up elastic stretching structure and can make compact heap 4 upwards
It is raised above, in order to which product to be positioned over to the centre of two pieces of compact heaps 4, when jack-up cylinder 2 is moved downward, elastic stretching structure
Nature is will then revert to, therefore, the compact heap 4 can be quickly by the clamping product between being placed therein.
Wherein, the elastic stretching structure includes center connecting shaft 5, the compression spring being sheathed in center connecting shaft 56
And the clamping screw 7 being connected with center connecting shaft 5, it is provided with the jig main body 3 and is adapted to the size of compression spring 6
Accommodating cavity (not marked in figure), the center connecting shaft 5 and compression spring 6 be installed vertically in accommodating cavity, described to compress
The centre of block 4 is provided with ladder hole, and clamping screw 7 is from top to bottom through ladder hole and the screw top of center connecting shaft 5
Connection.
It is nature as shown in Figure 1, elastic stretching structure is in impaction state.The compression spring 6 is retracted position,
Center connecting shaft 5 is pushed down on so that compact heap 4 compresses product.When jack-up cylinder 2 is by the jack-up of center connecting shaft 5, the pressure is compressed
Contracting spring 6 causes compact heap 4 to unclamp, and fixture is in open mode, can take out product.When new product is placed on into jig main body
On 3, jack-up cylinder 2 is unclamped, compression spring 6 returns to nature by compressive state, realize again and compress product.This practicality is new
Type is effectively saved fixture space, it is to avoid existing fixture volume is big, the situation of pipeline complexity winding.The utility model passes through bullet
Property stretching structure product clamping, is purely mechanic power, is influenceed that for minimum, product quality can be lifted by extraneous factor.
Further, the bottom of the center connecting shaft 5 is connected with annular contact piece 8, and annular contact piece 8 and center
Connecting shaft 5 is integrally formed.The diameter of the center connecting shaft 5 is less than the diameter of annular contact piece 8, is easy to 6 sets of compression spring
In center connecting shaft 5；In addition, the annular contact piece 8 can play a part of support, the jack-up to compression spring 6
The piston rod of cylinder 2 is larger to the active force area of annular contact piece 8.
Further, side protrusion of the compact heap 4 in is provided with compressed part 9, and the compressed part 9 is with compressing
The pack port of one " 7 " word of formation of block 4, can be very good to compress the both sides of product in the pack port of " 7 " word.
In the utility model, diagonally the positioning for being easy to the Fast Installation jig main body 3 is provided with the support panel 1
Latch 10.The jig main body 3 is by the location and installation of fastening screw 10 on support panel 1, it is ensured that elastic stretching structure and top
Play the vertically correspondence of cylinder 2.
It is described above, only it is the utility model preferred embodiment, not makees any formal to the utility model
Limitation, although the utility model is disclosed as above with preferred embodiment, but is not limited to the utility model, any to be familiar with sheet
