Due on base 2, in other embodiments of the invention, clamping arm 22 can also be provided separately with base 2；Workpiece 3, which has, to be supplied
The compressed part that pressure head 223 abuts.
Clamping arm 22 is arranged at the relative both ends of base 2 and is advantageous to be mounted with the bracket 1 of workpiece 3 by base in the present embodiment
2 side is moved to the top of base 22.
In some of the present invention, the quantity for being arranged at the end pressure head 223 of rotation section 222 is not limited to one, reference chart
Shown in 10, the end set of rotation section 222 in the present embodiment has three pressure heads 223, in other embodiments of the invention, pressure head
223 can also set other quantity, be arranged such the adaptation that can meet clamping arm to different workpieces 3.Both different workpieces 3 were entered
When row compresses, it may be necessary to the diverse location of workpiece pressing 3, set multiple pressure heads 223 to disclosure satisfy that the compression to diverse location
It is required that.
With reference to shown in Fig. 1, Fig. 2, Fig. 3, in order that what bracket 1 can be substantially before being fixed by top mechanism is positioned at bottom
On seat 2, two the second cylinders 23 that can jack up piston rod 230 straight up are further fixed on base 2, two are provided with bracket 1
The first sets of holes 11 passed through after the individual jack-up for the piston rod 230 of the second cylinder 23.Specifically, two the second cylinders 23 are oppositely arranged
In the both ends of base 2, the top of the piston rod 230 of the second cylinder 23 is preferably to have chamfering structure, in order to which piston rod 230 is inserted
Enter in the first sets of holes 11；In specific implementation process, the sectional dimension of the first sets of holes 11 is slightly larger than the section chi of piston rod 230
It is very little so that bracket 1 can carry out certain position adjustments with respect to base 2.
In the present embodiment, with reference to shown in Fig. 2, Fig. 3, Fig. 4, it is provided with the side wall of avoidance area 10 of bracket 1 for the first gas
Cylinder stretches the second sets of holes 12 stretched into during the ejection of 21 piston rods 210.In specific implementation process, with reference to shown in figure 2, Fig. 3, the first side wall
A sets of holes are fixed with 101 and form plate 120, two sets of holes are fixed with second sidewall 102 and form plate 120, the second sets of holes 12
Be formed at sets of holes formed plate 120 on, three the first cylinders stretch 21 piston rods 210 ejection after be respectively protruding into three the second sets of holes 12 with
1 liang of side wall being oppositely arranged of bracket is abutted, is so relatively easy to realize the positioning that the first cylinder is stretched between 21 and bracket 1.
With reference to shown in figure 2, Fig. 4, some supporting tables 14 for support workpiece 3 are provided with the bracket 1 in the present invention.
For the present invention, in specific implementation process, in order to realize the intelligent Application of loading assembly, loading assembly
