Description

Technical Field

[0001] The utility model relates to the field of workpiece positioning, in particular to an inflatable workpiece positioning jig. Background Art

[0002] In various machining processes, it is necessary to position and fix the workpiece to be machined.

[0003] like Figure 1 As shown, a box-shaped workpiece, some of which will be coated, printed or labeled on the outer surface before leaving the factory. Since there are fewer processing surfaces involved, the currently commonly used positioning method is to open a placement groove that conforms to the product on the mounting plate, and place the product in the placement groove for positioning. Although this method is convenient for positioning, in order to avoid shaking of the box-shaped workpiece during processing, the placement groove is generally tightly fitted with the product, which makes it inconvenient to take out. The inventor aims to provide a technical solution to solve this problem. Utility Model Content

[0004] The utility model aims to provide an inflatable workpiece positioning fixture, which has the advantages of being able to stably fix a box-shaped workpiece and facilitate blanking.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions: an inflatable workpiece positioning fixture, comprising:

[0006] A base, on which a support block for supporting the box-shaped workpiece from the inside is fixed;

[0007] a pressing member slidably mounted on the base; and

[0008] An airbag is provided on the base and connected to an external air supply device, and the pressing member is connected to the airbag. The inflation of the airbag drives the pressing member to slide and applies a pressing force to the pressing member so that the pressing member presses and fixes the box-shaped workpiece to the support block.

[0009] Through the above technical solution, when installing the box-shaped workpiece, the workpiece is buckled on the support block, and the support block supports the box-shaped workpiece from the inside to position and support it. Then, the external air supply equipment inflates the airbag, and the inflation of the airbag pushes the clamping piece to slide. After the clamping piece abuts the box-shaped workpiece, air is continuously supplied so that the airbag applies a clamping force to the clamping piece and presses the box-shaped workpiece to the support block. When the processing is completed and disassembly is required, it is only necessary to extract the gas from the airbag to cancel the fixation of the box-shaped workpiece, thereby removing the box-shaped workpiece, and unloading is convenient and quick.

[0010] In one embodiment of the present invention, a plurality of support blocks are arranged around the base, the airbag is arranged in the middle of several support blocks, the clamping members are arranged in a one-to-one correspondence with the support blocks, and several of the clamping members are connected to the airbag.

[0011] Through the above technical solution, multiple box-shaped workpieces can be fixed at the same time through one air supply, thereby realizing batch processing and improving efficiency.

[0012] In one embodiment of the present invention, an upper cover fixed to the base is further included, and the upper cover is used to limit the longitudinal expansion distance of the airbag and thereby increase the lateral expansion distance.

[0013] Through the above technical solution, the expansion amount of the airbag in the ineffective direction is reduced, ensuring that the airbag can exert sufficient force on the pressing member in the lateral direction.

[0014] In one embodiment of the present invention, the airbag is glued and fixed to the base, and an air nozzle is fixed on the airbag and is arranged to pass through the base. The air nozzle is connected to an external air supply device through an air pipe.

[0015] Through the above technical solution, the external air supply equipment supplies air to the airbag through the air nozzle and the air tube, and the airbag is fixed to ensure that the airbag can be retracted to the preset position and ensure stability in subsequent use.

[0016] In one embodiment of the present invention, a support rod is fixed to the upper surface of the base for supporting the upper cover so that the upper cover is spaced apart from the base.

[0017] The above technical solution ensures that there is enough space between the upper cover and the base to accommodate the airbag.

[0018] As described above, the pneumatic workpiece positioning fixture of the present invention has the following beneficial effects:

[0019] When installing the box-shaped workpiece, the workpiece is buckled on the support block, and the support block supports the box-shaped workpiece from the inside to position it. Then, the external air supply equipment inflates the airbag, and the inflation of the airbag pushes the clamping part to slide. After the clamping part abuts the box-shaped workpiece, air is continuously supplied so that the airbag applies a clamping force to the clamping part, pressing the box-shaped workpiece to fix it on the support block. When the processing is completed and it needs to be disassembled, it is only necessary to extract the gas from the airbag to cancel the fixation of the box-shaped workpiece, thereby removing the box-shaped workpiece, making unloading convenient and quick.
