Description
Technical Field
The utility model belongs to the technical field of electric jar equipment, concretely relates to electronic jar of high accuracy.
Background
The existing precision control of the electric cylinder has 2 types, and the precision of the electric cylinder is controlled by directly depending on the precision of a servo motor and reading data of an encoder. The mode is not made into a closed loop and only reflects the precision of the motor, and the actual precision of the electric cylinder is unknown. The other one is that an external displacement sensor is added, the displacement sensor is fixedly connected with the front end of the piston rod and is made into a closed loop through the external sensor, the displacement sensor is directly detected at a connecting part in the mode, the transmission of the middle screw rod nut is not detected, the electric cylinder is connected in a way, and the electric cylinder still needs to be abducted when being fixed, so that the problem is solved, and the requirements of people are met.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an electronic jar of high accuracy to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an electronic jar of high accuracy, includes electric jar main part and speed reducer, the speed reducer matches there is servo motor to be connected with electric jar main part drive through transmission assembly, electric jar main part side-mounting has the guide rail, and slidable mounting has middle connecting block on the guide rail, installs the grating chi on the middle connecting block.
Preferably, the piston inside the electric cylinder main body is fixedly connected with the middle connecting block.
Preferably, a drag chain is connected between the electric cylinder main body and the grating ruler.
Preferably, the electric cylinder body is provided with a switch bracket, and the switch bracket is provided with a photoelectric switch.
Preferably, the inner cavity of the electric cylinder main body is matched with a pressure sensor for monitoring pressure.
The utility model discloses a technological effect and advantage: this electronic jar of high accuracy through the displacement change of sensor direct detection junction department, reduces middle transmission link, makes the precision detection higher, and whole detection device's connection is all fixed on the cylinder body, makes the installation of electronic jar lower part simpler.
Drawings
Fig. 1 is a schematic view of the main structure of the present invention.
