The method used in the utility model is a conventional method if no special provisions are made; the raw materials and the apparatus used are, unless otherwise specified, conventional commercially available products.

Example 1

As shown in fig. 1, a multi-station inclined plate jig mainly comprises a platform 1, support legs 2, a corner cylinder 3 and a positioning structure 4.

The platform 1 is of a flat-plate structure and is used for supporting a flat-plate workpiece. The platform 1 is respectively provided with a supporting leg 2 at two sides of the lower surface thereof for supporting the main structure;

the platform 1 and the supporting legs 2 are spliced obliquely, and the surface of the platform 1 and the horizontal plane form an included angle; preferably, the supporting leg 2 is a vertical plate structure 201, the upper end surface is processed into a slope, the inclination angle between the slope and the horizontal plane is designed according to the actual processing requirement, and the angle shown in the embodiment is only used for illustration and is not specifically limited. Processing screw hole on the domatic of landing leg 2 to at the position processing through-hole that platform 1 corresponds, it is fixed with landing leg 2 with platform 1 through the bolt afterwards. Therefore, when workpieces in different batches are faced, if different clamping angles are adjusted, the supporting legs 2 only need to be machined again, and part of input cost is reduced. Further, in order to facilitate the integral installation, a symmetrical U-shaped groove 202 is formed at the lower portion of each leg 2, as shown in fig. 2 and 4, for fixing with an external installation site.

In this embodiment, as shown in fig. 3, two clamping areas 5 are arrayed on the upper surface of the platform 1, each clamping area 5 serves as a processing station, and four sets of corner cylinders 3 are symmetrically arranged in each clamping area 5 and distributed at corners of the clamping area 5. As shown in fig. 2, a mounting through hole (not shown) is formed in the platform 1, and the cylinder 301 of the corner cylinder 3 is mounted on the lower surface of the platform 1 by a bolt, and the cylinder piston rod passes through the through hole, so that the clamping arm 302 of the corner cylinder 3 is located above the upper surface of the platform 1.

And a positioning structure 4 is further arranged in the clamping area 5 and used for positioning and assisting in fixing the workpiece to be processed. As shown in fig. 2, the positioning structure 4 includes a positioning pin 402 and a limit boss. The limiting boss is of a columnar structure and is coaxially arranged at the top of the positioning pin 402. In order to ensure that the limiting boss plays a limiting role, when the clamping arm 302 of the corner cylinder 3 is located at the clamping position, the end part of the clamping arm 302 is just above the limiting boss, so that the clamping arm 302 can be prevented from damaging a flat-plate-shaped workpiece through the process.

Preferably, in this embodiment, the limiting boss and the positioning pin 402 are an integral structure. The platform 1 is provided with positioning holes which correspond to the positioning holes on the workpiece one by one. The positioning pins 402 of the positioning structure 4 are mounted in the positioning holes. Further, in order to fix the positioning pin 402, a counter bore is coaxially processed on the back surface of the positioning hole, and a hole is punched so that the counter bore communicates with the positioning hole. Correspondingly, a threaded hole is formed in the bottom of the positioning pin 402, and as shown in fig. 2, the positioning pin 402 is finally connected with the positioning pin 401 through a countersunk hole by a bolt 401, so that the positioning structure 4 is assembled.

Example 2

In this embodiment, on the basis of the above embodiment, the positioning structure 4 is further improved, as shown in fig. 5 and 6, an internal thread is processed in the hole passage where the countersunk hole is communicated with the positioning hole, the bolt 401 is selected as a long bolt, and a corresponding threaded through hole is formed in the positioning pin 402 along the axis and is matched with the bolt 401.

Preferably, in this embodiment, the length of the thread of the bolt 401 is greater than the length of the positioning pin 402, so that after the bolt 401 is matched with the positioning pin 402, a small amount of end portions are exposed on the upper end surface of the positioning pin 402, and the exposed structure is used as a limiting boss. The design can save the spacing boss of independent processing like this, and limit structure height-adjustable, when needs increase or reduce spacing boss height, earlier anticlockwise (in the same direction as, anticlockwise viewing direction is the direction from top to bottom in figure 5) unscrew locating pin 402, twist bolt 401 again, make it rely on the screw thread adjusting bolt 401 axial position in the pore, adjust clockwise tightening locating pin 402 after targetting in place again, make it form double thread anti loosening structure with bolt 401 and pore internal thread, it is firm to fix.

Preferably, as shown in fig. 6, in order to ensure that the locating pin 402 is easily screwed, two flat openings are designed to be machined on the peripheral side surface of the locating pin 402 to provide the force application position of the open wrench, and the remaining arc surfaces on the side surface of the locating pin 402 can still play a role in locating.
