Three-dimensional fine-adjustment worktable for thread scanning meter

Abstract

The invention relates to a thread meter, in particular to a three-dimensional fine-adjustment worktable for a thread scanning meter. In the prior art, due to the lack of the three-dimensional fine-adjustment worktable for the thread scanning meter, the thread metering is complex and the metering precision is low. In the three-dimensional fine-adjustment worktable, an upper worktable (8) is fixed with a pin shaft (7); an adjusting screw (10), the upper worktable (8) and the pin shaft (7) rotate together in a hole in a support (6); a middle layer (11) is provided with an adjusting screw rod (21) and an ejector pad (20); a groove is formed on the ejector pad (20), and the adjusting screw rod (21) extends into the groove; a base (12) is connected with guide rails (16) which are connected with a connecting block (15); the guide rail slide (14) is arranged on the lower part of the middle layer (11); and one end of the middle layer (11) is connected with a micrometer head (22). The worktable has the advantages that: the adjustment precision is high; the friction in rotation is small; and dovetail groove can be detached quickly and conveniently by vices.

Description

technical field [0001] The invention relates to a thread measuring instrument, in particular to a special three-dimensional fine-tuning workbench for a thread scanning measuring instrument. Background technique [0002] Threaded connection is widely used in various tools, products and equipment due to its firm connection and convenient assembly and disassembly. Due to the strong thread interchangeability and high degree of standardization, it needs to be strictly tested. In the existing thread scanning measuring instrument, the measured part is fixed by a block positioning device, which is fast and reliable for the detection of standard parts and common parts. But for parts with small batches, or parts with large volume and irregular shape, the design and production of special block gauges will increase the cost. For these irregular parts, the prior art adopts the combination of three-dimensional fine-tuning workbench and special vise to replace the block gauge. Fix the p...

Problems solved by technology

Chinese patent 200710133666.4, "Three-dimensional workbench of stylus-type three-dimensional roughness measuring instrument", due to different scope of application, cannot be used for thread scanning measuring instrument

At the same time, the three-dimensional workbench of the roughness measuring instrument uses a worm gear mechanism to make it rotate around the X, Y, and Z axes. It has a total of 6 layers of structure, which is bulky, complex in structure, and has many components and high cost.

[0003]The current state of the art is that there is no special three-dimensional fine-tuning workbench for thread scanning measuring instruments in the world, which makes thread measurement troublesome and the measurement accuracy is not high
