Abstract

This invention relates to industrial vehicle engineering. The purpose of the invention is to increase the productivity of the device for stepping movements. Based on 1, a trolley (T) 3 with L-shaped edges is moved along the longitudinal guides 2. Onboard the base 1, a gripping mechanism (3M) 4 with a drive of 5 linear displacements T 3 is installed. The latter has transverse guides 7 along which an additional T 8 with L-shaped beads, a ZM 9 with a drive of 10 linear displacements. Based on 1 and T 3, adjustable stops 11-14 are installed, which are in contact with sensors 15-- 18 in the extreme positions T 3 and 8. When ZM 4 and 9 work, L-shaped beads T 3 and 8 are clamped and by means of actuators 5 and 10 move them in the right direction for a specified number of steps. An increase in the productivity of the device is achieved by eliminating the need for changeover when the product is moved to the T 8 in the transverse direction. 2 Il. Yu

The invention relates to industrial transport engineering, in particular to devices for step-by-step mixing of products for connecting them by resistance spot welding, and can be used in other branches of the national economy for the automated servicing of several equipment positions in the manufacture of products of variable frame sizes.

The purpose of the invention is to increase productivity.

FIG. 1 shows a device for step mixing, plan view; in fig. 2 shows section A-A in FIG. one.

The device comprises a base 1 with longitudinal non-rotating 2 fixed on it, in which it is installed with the possibility of reciprocating movement in the longitudinal direction of the main 2 trolley 3.

The base 1 and the trolley 3 are made with L-shaped sides. Onboard the base 1 there is a gripping mechanism 4 with a drive 5 of a longitudinal linear agitator, an e-truck 3, which also has a gripping mechanism 4 with a drive 5, made in a particular case in the form of a pneumopilder, the rod of which has a gear cut, in contact with a gear wheel, the axis of which is installed in the pneumatic cylinder body. In the guides of the pneumatic cylinder body, a gripping mechanism body is mounted, which is connected by means of levers with length-adjustable pushers fixed on the gear axles. The body of the gripping mechanism has a slot, which includes the side of the movable trolley and in which the cheeks of the pneumatic chambers, made in the form of elastic plates with metal plates, are placed.

The base unit contains the control unit 6 for the energy supply system (in particular, in the case of a pneumatic system with a control circuit). The carriage 3 is provided with transverse guides 7 fixed on it, in which an additional carriage 8 is installed with the possibility of reciprocating movement, also made with L-shaped beads. On the trolley 3, an additional gripper mechanism 9 with a drive 10 of the trolley 8 is mounted. On the sides of the base 1 there is one pair of adjustable stops 11 and 12 fixed at the required distances with screw clamps. On the sides of the trolley 3, another pair of adjustable stops is also placed. 13 and 14. On carts 3 and 8, two pairs of contact sensors 15, 16 and 17, 18 are installed for engagement with stops 11, 12 and 13, 14.

Moreover, the adjustable stops 11, 12 of one of the pairs are fixed on the base 1 in the extreme positions of the main carriage 3, and the adjustable ramps 13, 14 of the other pair

mounted on the main carriage 3 in the extreme positions of the additional carriage 8. In this case, sensors 15, 16 of one pair are mounted on the main carriage 3 with the possibility of interaction with adjustable stops II,

12, located on the base 1, and the sensors 17, 18 of the other pair are mounted on an additional trolley 8 with the possibility of interaction with adjustable stops

13,14 placed on the main carriage 3

The device works in combination with a stationary welding machine (in a particular case with a spot contact welding machine). In the initial position the base

The welding carriage is in the opening, and the carriage 3 and carriage 8, in which the connected parts of the product are fixed, are mounted in guides 2 and 7 so that the electrodes of the welding machine are at the level of the right lower point of the contact connection of the parts (Fig. 1). Before putting it into operation, the device is adjusted to the dimensions of the contour of the contact joints of parts of the product. For this, the stops

II-14 are installed at the required distances from the sensors 15-18 and fixed in this position. On command from the control panel, via the control unit 6, the energy supply signal (in the particular case of compressed air from the shop air line) is supplied to the gripping mechanism 4 and the drive 5. The compressed air supply to the gripping mechanism 4 and the drive 5 occurs simultaneously, but since the feed throughput to the actuator 5 is less than the feed throughput to the gripping mechanism 4, the gripping mechanism 4 is first triggered by clamping the side of the carriage 3. Then the actuator 5 moves the carriage 3 by the required pitch, the magnitude of which can be adjusted It is the size of the departure pushers fixed pas axes gear drive shaft 5. During retraction of the pneumatic cylinder actuator 5 occurs unclamping cheeks gripping mechanism 4 and the actuation electrodes of the welding machine. This process of moving the carriage 3 will take place until the lever 15 of the sensor 15 contacts the stop 11. When the sensor 15 is triggered, the control unit 6 stops the supply of energy to the gripping mechanism 4 and the drive 5 and supplies the energy to the gripping mechanism 9 and the drive 10, through which the carriage 8 moves with a feed pitch until the sensor 18 operates with the abutment 14. After this, the drive 5 is switched on again with the gripping mechanism 4, at the same time the drive 5 of the drive 5 becomes the working stroke and is made Agov moving the carriage 3 in the reverse direction until the actuation position sensor 16 with a focus 12. Then again turned feed air into the gripping mechanism 9 and the actuator 10 and the carriage 8 is moved with the intermittent supply of the starting position. In this case, the stop is made when the sensor 17 contacts the stop 13. During this period, the electrodes of the welding machine are located at the initial initial welding point. The product is removed. New parts of the product are laid and the process is repeated.
