specific Embodiment approach 1

[0031] Specific implementation mode one: as Figure 1-5 As shown, the automatic cable insertion and removal device for mass centroid measurement in this embodiment includes an upper layer pin mechanism 1 and a lower layer jack mechanism 2. On the end face, the lower end face of the lower jack mechanism 2 is fixed on the upper end face of the bottom measuring device; the upper pin mechanism 1 includes a door-shaped fixing seat 1-1 and a pin fixing seat 1-2, and the pin fixing seat 1- 2 is installed on the bottom of the door-shaped fixed seat 1-1, the lower socket mechanism 2 includes the socket mounting seat 2-1, the elastic mechanism 3 and the cable socket 2-2, and the cable socket 2-2 passes through the elastic mechanism 3 Installed on the upper part of the socket mounting base 2-1, when the upper tooling falls to the lowest point, the pins of the pin holder 1-2 are separated from the cable jack 2-2, and when the upper tooling rises to the highest point, The pins of the pin ...

specific Embodiment approach 2

[0034] Specific implementation mode two: as figure 1 and figure 2 As shown, the upper end surface of the door-shaped fixing seat 1-1 in this embodiment is provided with an outer edge, and the outer edge of the door-shaped fixing seat 1-1 is fixedly integrated with the upper layer tooling of the mass centroid measuring device through four bolts. Such a design facilitates the installation of the gate-shaped fixing seat on the upper tooling of the mass centroid measuring device. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0035] Specific implementation mode three: as figure 1 and image 3 As shown, the outline of the socket mounting seat in this embodiment is in the shape of a "door", and the lower end of the socket mounting seat 2-1 is provided with an outer edge, and the outer edge of the socket mounting seat 2-1 passes through four bolts and the bottom measuring device Fixed as one. It is designed so that the socket mount can be easily installed on the bottom measuring device. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses an automatic cable inserting and pulling device for mass and centroid measurement, which relates to an automatic cable inserting and pulling device and aims at solving the problem that the mass and centroid measurement result accuracy is influenced by tiny changes of a cable connected with an electronic device during the existing mass and centroid measurement process. The upper end of an upper inserting pin mechanism is fixedly arranged on the lower end surface of an upper tool of the mass and centroid measurement device; the lower end surface of a lower jack mechanismis fixedly arranged on the upper end surface of a bottom measurement device; the upper inserting pin mechanism comprises a door-shaped fixing seat and an inserting pin fixing seat; the inserting pin fixing seat is arranged at the bottom part of the door-shaped fixing seat; a cable jack is arranged at the upper part of a jack mounting seat through an elastic mechanism; and when the upper tool fallsto the lowest point, the inserting pin of the inserting pin fixing seat and the cable jack are in a separated state, and when the upper tool rises to the highest point, the inserting pin of the inserting pin fixing seat and the cable jack are in a tight connection state. The device disclosed in the invention is used for mass and centroid measurement on subjects such as a rocket, a car and a submarine.

Description

technical field [0001] The invention relates to an automatic cable insertion and extraction device for mass centroid measurement, which belongs to the technical field of measurement. Background technique [0002] For the mass centroid measurement of large-scale objects such as rockets, automobiles, and submarines, the existing measurement technology is mainly the static moment balance method, that is, three or four load cells are used to measure the weight of the product under test, and three (or four) load cells are used to measure the weight of the product under test. 1) the readings of the load cell and their relative positional relationship to calculate the mass center of mass position of the product to be tested. [0003] The general steps of the mass centroid measurement process are: 1. Measure the mass centroid of the tooling without loading the tested product; 2. Load the tested product and measure the total mass centroid of the product and the tooling; 3. Change the...
