located on the plates 2 of the simulator s of three planes. One of the parts of the threaded pair of nuts beat the bolt 5 is fixedly connected to the base plate 3 by means of the quick coupling. The trainee conducts the threaded connections with the help of wrenches at the workplace. When correct

in the assignment, when the device control contacts of all threaded pairs are closed, the signal passes through the logic device to the teacher’s console. In case of an incorrectly executed reference-1, there is no signal in the logic device, k Il.

The invention relates to devices for grafting professional skills and can be used as a simulator for grafting practical skills in disassembling and assembling threaded connections.

Isoosten stand for assembling threaded connections, containing the base, motor, grip of the threaded element and torque sensors.

The closest to that proposed by the technical essence is a simulator for imparting practical skills in disassembling and assembling threaded connections, which contains a support plate and one of the elements of a threaded connection fixed on it.

The disadvantage of the known simulator is that it cannot provide the necessary range of threaded connections at one workplace, and also that it does not have remote control over the work performed.

The purpose of the invention is to increase the effectiveness of learning.

The simulator, which contains a support plate and one of the elements of a threaded joint fixed to it, is equipped with a frame, four additional support plates fixed to the frame perpendicular to the main body, rigidly connected to it, with a U-shaped support plate, the posts of which are fixed to the frame perpendicular to the main .of the base plate, and forming a parallelepiped with other plates, and devices for controlling the tightening of threaded connections, each of which is made in the form of a threaded connection enclosing a fixed element and closed captive on one end of the dielectric support plate holder mounted at its other end two contacts intended for connection to Warning embracing fixed

the element of the threaded connection of the washer to interact with the contacts, and the spring placed between the washer and the support plate, and the threaded elements attached to all the supporting plates and facing the inside of the parallelepiped.

FIG. 1 shows a simulator, a general view; in fig. 2 - the same, top view; in fig. 3, node I in FIG. 1 (installation diagram of fixed elements of threaded pairs and control elements); in fig. k - logic circuit of remote control and control.

The simulator consists of a frame 1, on which five support plates 2 are fixed by means of a welded joint. The base plate 3 is fixed on the frame 1 by means of four bolts k. The base plate 3 is smaller than all the other plates, and has a U-shaped profile for accessing the inside of a rectangular parallelepiped whose sides are base plates. Threaded elements, namely bolts 5 and nuts 6, are fastened to the support plates 2 and 3 by means of a welded joint.

The distance between adjacent threaded elements is 80 mm to create conditions of limited space when operating with wrenches. Other elements of threaded pairs, namely bolts 7 and nuts 8 (Fig. 2), are located in a special box. The simulator contains control devices, each of which consists of two contacts 9 installed on a textolite holder 10, washers 11 and springs 12. Holder 10 with contacts 9 secured to the base plate 3 by means of two screws 13 coaxially controlled threaded pair. The washer 11, which acts as a contact disk, moves when the threaded pair is tightened along the bolt 5 fixed to the base plate, on which it is mounted, or together

with a bolt if the fixed member is a nut 6. A spring 12 is inserted between the yoke 10 and the washer 11 to create a tightening force.

The simulator works as follows.

Having removed the work, the student presses the button. The work is ready (Fig. 3). On the remote, the teacher tans the board. Ready for work. The teacher is pressing the button. At the workplace, the board lights up. Work is started and the clock is turned on. The student proceeds to the acquisition of the connection and tightening the threaded pairs in any sequence. The trainee tightens threaded connections using wrenches at the workplace. After completing the task, the student presses the Job completed button.

With a correctly performed task, when the contacts of the control devices of all threaded pairs are closed, the signal passes through the logic device to the teacher’s console. On the remote, the teacher stops the clock and lights up the board. I finished the work. If the adjustment is performed incorrectly, there is no signal in the logic device, therefore, the clock is not turned off. The evaluation parameter, which determines the degree of fitness of the student, is the time required to complete the task.

The simulator provides the development of the motor and sensory
