Abstract
The utility model relates to a portable screw bore diameter measuring device comprising an internal diameter dial indicator (1) and extension rods (5). The internal diameter dial indicator (1) comprises a support (11), a measuring head (12) and a sensor (4). One end of the support (11) is provided with the measuring head (12) in a connection way, and the other end is provided with a connecting block (2). There are multiple extension rods (5) which are connected in an end-to-end way so that a long rod is constructed. One end of the long rod is connected with the support (11) via the connecting block (2). The sensor (4) is arranged on one side of the extension rods (5). A top rod of one end of the sensor is inserted into one end of the support (11). The sensor (4) is connected and fixed with the support (11) via a clamping block (3) which is installed on the external side of the top rod of the sensor. The sensor is connected with an external digital display device (6) via a transmission wire (7). The portable screw bore diameter measuring device is simple in structure. The extension rods are applied to be combined with the internal diameter dial indicator so that screw bore diameter with large depth can be detected, and thus the portable screw bore diameter measuring device is convenient to operate and accurate in measurement.
Description
Technical field
The utility model relates to the mechanical measurement apparatus field, particularly relates to a kind of portable spiral shell thorax aperture measurement device.
Background technology
Plastic extruder is a kind of machinery of field of textiles through commonly using, and the abrasion condition in its screw rod and Luo Tangmei district directly affects the extrusion performance of plastics, thus often need to monitor constantly control, so that research each district's shearing force of plastics and plasticizing situation.But in daily measuring process, simple and easy vernier caliper commonly used only can be tested the local internal diameter in the spiral shell thorax outside at ordinary times, and high-accuracy metal detecting device is difficult to detect the screw rod internal diameter on large-scale stationary installation online or on the spot, use dial bore gage simple in structure also because length can not detect the spiral shell thorax internal diameter that the degree of depth is large not.
