Description

Technical Field

[0001] This utility model belongs to the technical field of tooling fixtures, and in particular relates to a three-axis tooling fixture with two workstations. Background Technology

[0002] Tooling, also known as process equipment, refers to the general term for all kinds of tools used in the manufacturing process, including cutting tools, fixtures, molds, measuring tools, inspection tools, auxiliary tools, fitter's tools, workstation equipment, etc.

[0003] Existing tooling fixtures have some shortcomings in use. They are all single-station clamping fixtures, which cannot stably clamp two workpieces of the same or different types at the same time for further processing. Furthermore, existing tooling fixtures do not allow for convenient workpiece clamping and replacement. Based on this, a dual-station three-axis tooling fixture that can solve the above problems is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-station three-axis tooling fixture, which aims to solve some shortcomings of existing tooling fixtures. Existing tooling fixtures are all single-station clamping fixtures, which cannot stably clamp two workpieces of the same or different types at the same time for further processing. In addition, existing tooling fixtures do not allow for convenient clamping and changing of workpieces.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A dual-station three-axis tooling fixture includes a tooling base plate with multiple limiting blocks on the base plate. A first clamping unit for clamping a workpiece is positioned between adjacent limiting blocks. Each clamping unit includes multiple arrayed first adjusting blocks, with a second adjusting block positioned between each array. The first adjusting block closest to the middle limiting block is fixedly connected to the tooling base plate. Each first adjusting block has a first inclined surface, and each second adjusting block has a second inclined surface. Symmetrically arranged snap-fit ​​plates are fixedly connected to the sides of each second adjusting block. Each first adjusting block has a first snap-fit ​​groove that mates with the snap-fit ​​plates, and each second adjusting block has a first threaded hole containing a first screw. The first adjusting block is threadedly connected to the tooling base plate via the first screw.

[0007] The lower end of the limiting block is provided with a snap-fit ​​protrusion, and the tooling base plate is provided with a second snap-fit ​​groove that mates with the snap-fit ​​protrusion. The limiting block is provided with a plurality of second threaded holes, and a second screw is provided in the second threaded hole. The limiting block and the tooling base plate are connected by the second screw.

[0008] A first pressure plate is fixedly connected to one of the second adjustment blocks in the same group, and the first pressure plate is rotatably connected to a second pressure plate via a rotating shaft.

[0009] The lower end face of the second pressure plate is in contact with the upper end face of the second adjustment block.

[0010] The tooling base plate is provided with a second clamping unit for limiting the position of the workpiece body.

[0011] The second clamping unit includes a connecting frame fixedly connected to the side of the tooling base plate. A first guide rod is fixedly connected inside the connecting frame. A first movable plate is fixedly connected to the outside of the first guide rod. The side of the first movable plate is connected to the side wall of the connecting frame through a second spring for providing elastic force. The second spring is sleeved on the outside of the first guide rod. A clamping block is fixedly connected to the upper end of the first movable plate. A limit protrusion is provided on the side of the tooling base plate away from the connecting frame.

[0012] The upper end of the clamping block is provided with an arc-shaped surface, the tooling base plate is provided with a process groove, the process groove is provided with a third threaded hole, and the third threaded hole is connected to the outside through a third screw.

[0013] A second movable plate is fixedly connected to the lower end of the first adjusting block away from the middle limiting block. A third snap-fit ​​groove that cooperates with the second movable plate is provided on the tooling base plate. A second guide rod is provided in the third snap-fit ​​groove. The second guide rod passes through the second movable plate. The side of the second movable plate is connected to the side wall of the third snap-fit ​​groove through a third spring for providing elasticity.

[0014] The beneficial effects of this invention are as follows: by adjusting the vertical position of the first adjusting block with the first screw, the distance between the second adjusting block and the workpiece body can be adjusted. Under the action of the limiting block, the workpiece body is clamped and limited. The dual-station clamping improves work efficiency, reduces the clamping time for technicians, and improves the requirements for installation and reduces processing steps in actual processing.
