Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tooling fixtures, in particular to a high-precision tooling fixture with positioning and clamping functions. Background Art
[0002] Fixtures are process devices used to quickly fasten workpieces during processing so that the machine tool, tool and workpiece maintain the correct relative position. In other words, fixtures are indispensable components of mechanical processing. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite, intelligent and environmentally friendly directions, fixture technology is developing towards high precision, high efficiency, modularity, combination, universality and economy.
[0003] Existing tooling fixtures often place the workpiece directly inside the fixture, and then two clamps move to clamp the workpiece. Since the workpiece is not positioned, the workpiece is often in an offset position after clamping, affecting subsequent processing. For this reason, we propose a high-precision tooling fixture with positioning and clamping functions. Utility Model Content
[0004] The main purpose of the utility model is to provide a high-precision tooling fixture with positioning and clamping functions, which can effectively solve the problems in the background technology.

[0007] In order to move the threaded tube, as a high-precision tooling fixture with positioning and clamping functions of the utility model, the front side of the first positioning angle frame is fixedly connected with the threaded tube, and the internal threads of the threaded tube are connected with a threaded column.
[0008] In order to make the threaded column rotate more smoothly, the utility model provides a high-precision tooling fixture with positioning and clamping functions. The threaded column is installed inside the support seat through a bearing, and the support seat is fixed to the front side of the first mounting block by bolts.
[0009] In order to facilitate the adjustment of the two first positioning angle frames for position movement, the utility model provides a high-precision tooling fixture with positioning and clamping functions. One end of the threaded column is fixedly connected to a handle, and the outer surface of the threaded column is provided with two sections of threads, and the spiral directions of the two sections of threads are opposite.
[0010] In order to enable the second positioning angle frame to move on the U-shaped column, as a high-precision tooling fixture with positioning and clamping functions, the back side of the second positioning angle frame is fixedly connected to a limiting frame, and the limiting frame is sleeved on the outer surface of the U-shaped column.
[0011] In order to facilitate the control of the second positioning angle frame to move and clamp the workpiece, the utility model is a high-precision tooling fixture with positioning and clamping functions. Both ends of the U-shaped column are fixedly connected to the push plate, and the back of the push plate is fixedly connected to an electric push rod, which is fixedly mounted on the second mounting block.
[0012] In order to make the fixture more secure, as a high-precision tooling fixture with positioning and clamping functions of the utility model, the first mounting block and the second mounting block are fixedly connected by a reinforcement rod.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The high-precision tooling fixture with positioning and clamping functions is arranged through the coordination between the first mounting block, the slide groove, the slider, the first positioning angle frame, the slide rail, the limit block, the second positioning angle frame, the limit frame, the U-shaped column, the push plate and the electric push rod. When the work needs to be clamped, the workpiece can be placed inside the first positioning angle frame to ensure that the workpiece is placed flat, and then the electric push rod is started. The electric push rod drives the push plate to move the second positioning angle frame to clamp the workpiece. Therefore, the workpiece can not only be clamped, but also positioned when placed, so that the workpiece is not easily displaced.
[0015] 2. This high-precision tooling fixture with positioning and clamping functions is configured through the coordination of the first mounting block, the slide groove, the slider, the first positioning angle frame, the handle, the threaded tube, the threaded column and the support seat. When the staff controls the handle to rotate forward, the threaded column can rotate forward, so that the two threaded tubes are close to each other, and the distance between the two first positioning angle frames can be adjusted. It is suitable for clamping workpieces of other sizes and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
