It allows the use of abrasive material, the particle sizes of which exceed the dimensions of the workpiece. In this case, when the parts have parts that are difficult to process, such as holes and grooves, it is practically impossible to achieve satisfactory machining results for the parts, since the inner surfaces of the holes and grooves are not exposed to abrasive material. Removing any internal burrs in the holes and grooves is also difficult. Thus, parts with holes and grooves are usually not machined with existing tumbling tools. Precision finishing processing of surfaces of parts requiring a large tolerance for processing involves initially performing a tumbling finishing operation that provides intensive cutting or grinding of parts (for example, swirling tumbling, centrifugal tumbling, etc., providing rough surface treatment), and then performing a tumbling operation another type providing precision surface treatment (for example, tumbling in a rotating drum followed by centrifugal tumbing).

A conventional finishing device, specially designed for finishing the internal surfaces of holes and grooves of parts, is unsuitable for finishing the external surfaces of parts or parts that should have rounded edges, since such devices cannot fundamentally perform the functions that a tumbling machine performs.

There are also methods of finishing parts, involving the use of acids or electrolytes for chemical or electrochemical polishing of parts. These methods provide polishing of the inner surfaces of the holes and grooves of the workpieces, however, they do not polish the outer surfaces of the parts, which is achieved only by tumbling, In addition, acid and electrolytes have a chemical effect on metals, removing oxide films from the surface of parts, which reduces the resistance of parts to and corrosion. It should also be noted that the tribological characteristics, the final processing of which is carried out by acids or electrolytes, are significantly impaired.

In order to eliminate the drawbacks noted above and, therefore, to solve the problems associated with these drawbacks, the present invention proposes the use of a combination of several types of gel coat

operations or combinations of certain types of tumbling operations and with other types of finishing processing of parts. To implement the proposed solution, various types of tumbling operations or other types

Finishing parts can be done automatically in a specific sequence.

The invention is implemented as a complex of several finishing devices

5 different types, each of which performs a specific finishing operation, which function in parallel or in series, and through which the workpieces pass automatically and

0 sequentially, subjected to various finishing operations. It should be understood that all or part of the finishing apparatus included in the integrated installation used for the combined finishing of parts may be tumbling machines. Such tumbling machines include, for example, automatic tumbling machines with a rotating drum,

0 centrifugal wetting machines, circular finishing machines, reciprocating finishing machines, dry-type centrifugal tumbling machines, circulating vibratory damping machines

5 cars, vortex tumbling machines and electrochemical tumbling machines. Other types of finishing machines other than tumbling machines include sanding finishing machines, belt grinding machines, shot blasting machines, electrochemical finishing machines and brush finishing machines. Combinations of these various types of finishing machines are determined by the specific requirements for finishing parts. In other words, depending on the shape and material of the workpieces or on the capabilities of the finishing machines, one integrated system of machines may include a finishing machine of one type and a finishing machine of another type other than the first one, which are interconnected by a transport mechanism for transferring the processing 5 parts from one machine to another. Another complex system of machines may include a finishing machine of one type and several finishing machines of other types, which are interconnected by a transport mechanism that ensures the passage of the workpiece and first through the finishing machine of the first type, and then sequentially through the finishing machines other types. Dana ks multiplex system of finishing machines can include several finishing machines of various types, after which the details are further processed into the finishing machine of the first type. This complex system of finishing machines can also include finishing machines of various types. types forming one technological line. Finishing machines of various types can be combined into one production line by any approach - with SH1 vehicles, for example; p, manipulators, transport rots, belt conveyors, ladle conveyors, screw conveyors, vibration conveyors, Bf with tables, translucent jellies and other transport mechanisms. In the proposed complex C1 systems, any Tf vehicles can be used to transfer the parts to be processed between fiV

Below is a detailed description of the proposed finishing installation, which is carried out with reference to FIG. 1-7.

The design of the finishing installation, shown in Figs. 1 and 2, includes devices that perform the grinding operation with a diamond wheel, the operation of circular surface finish and the operation of tape lapping. The considered finishing installation is designed for processing shafts similar to those shown in Fig. 3 and requiring polishing surfaces and deburring. As shown in FIG. 3, the shaft to be finished has a section A, where an acute angle must be maintained after finishing, sections B, which are parts of a cylindrical surface and require surface polishing, and sections C, D and E, which represent the edges of the grooves requiring polishing of the internal surfaces and deburring. Details of this configuration are not amenable to tumbling, except for surfaces B that require circular tumbling. Taking into account the configuration of the part to be finished, the design of the finishing installation shown in Figs. 1 and 2 includes a grinding device with a diamond disk that polishes the surfaces of the grooves of the part, a device for removing burrs from the edges of the grooves of the part, and a tape finishing device for polishing acute-angled transitions the workpiece. The inlet conveyor shown in FIGS. 1 and 2 is an infinite batch conveyor 1, consisting of a plurality of sections, in each of which the part to be processed is mounted. The speed of the step conveyor 1 is selected in accordance with

the duration of the working cycle of the finishing installation. The installation of the workpieces on the conveyor 1 can be done manually or automatically using the appropriate automatic manipulator. Part 2 located on the conveyor 1 is fixed by gripping the first manipulator 3, which then rotates 90 ° with the part in the horizontal plane. In this position, the disk 4 grinding device performs grinding of the groove surfaces of the workpiece, indicated in Fig. 3 by the letters C, D and E, Disk grinding device will be described in detail below.

Upon completion of the grinding operation of the grooves of part 2, the gripper of the first manipulator 3 is again rotated in the horizontal plane by an additional 90 °, transferring the workpiece HS to the conveyor 5 of the circulation finishing device. At the same time, the second grip of the first manipulator 3 transfers the next part 2 from the inlet conveyor 1 to a disk grinding device, where the grooves of the part are then ground. The first manipulator 3 is not white. as shown in -fig. 1 and 2, but with four grippers, at the end of each cycle of finishing parts, it can be rotated 90 °. If the first manipulator 3 has only two grippers, then upon completion of the transfer of every second part 2 located in the second gripper to the conveyor 5, it must be rotated an additional 90 ° so that its first gripper is set opposite the end of the input conveyor 1. subsequent rotation of the manipulator 3 by 90 °, the part located in the first grip is set to the grinding position, and the second grip is aligned with the end of the inlet conveyor 1. The workpiece 2 is conveyed by one conveyor 5 for each finishing cycle by one ag and is set in a position in which it is fixed in the grip of the second manipulator 6, located on the input end 7 of the conveyor 5.

5, when the turret 13 is rotating, the spindles 9 and 11 attached to it make a circular motion inside the container 12. Upon completion of the surface finishing of the parts, the turret 13 stops at a position in which the workpiece is removed from the container 12. This position in FIG. 1 corresponds to the position of the spindle 11. After stopping the turret 13, the spindle 9 rises from

5 of the container 12 and releases the workpiece 2, which at the same time is fixed in the grip of the third manipulator 14. The third manipulator 14 sets the workpiece 2 back to

0 conveyor 5, which transports the part to the fourth manipulator 15. The fourth manipulator 15, after fixing the workpiece 2 in its grip, rotates 90 ° and sets the part a

5 tape finishing device, where the part is processed with polishing tape 16. Upon completion of all the finishing operations described above, the machined part is set by the fourth manipulator

0 15 to conveyor 17, which delivers the parts for the next process step. In Figure 2, reference numerals 18 indicate the control panel of the finishing unit, and reference numeral 19 denotes a magnetic separator used to collect and remove metal chips from the solution used in processing the parts with a diamond grinding disc. Reference numeral 20 denotes a container for a coolant and a hydraulic pump used to cool the solution and supply it to the workpiece.

The following describes the modifications of the proposed integrated finish installation, presented on the attached Fig.8-11.

5 In one of the modifications of the proposed complex finishing unit includes a bead-blasting finishing machine 54 and a vibrohulping finishing machine 55, equipped with an automatic separator. In this installation of shot blasting, the finishing process provides a finer study of the external and internal surfaces of the workpiece compared to tumbling finishing and, in addition, prevents the breakage and cnc; tnu: activation of the workpieces, increases the corrosion resistance of the parts and improves the quality of the surfaces of the parts The bead-blasting finishing machine includes a bead-blasting device and a pick-and-place device for containers with workpieces. Initially, the transport container with the parts to be shot-blasted is mounted on the pick-up table 56, where it moves along the rollers 57 and 58 to the lift 59, the Lift 59 delivers the transport container to the loading chute 60 of the shot blasting machine 54 and tilts the container so that the parts to be processed from the container fall into the machine, Details of the shot blasting machine shown in Fig.9; /; 11. The workpieces from the loading chute 60 enter the tumbling drum 61, which rotates in the direction of the arrow 62. The nozzle 63 directs a stream of abrasive material (for example, shot, aoracule material, glass balls and / / ears of sand) to the moving tumbling drum parts, ensuring the processing of parts surfaces, the process of processing parts in a tumbling drum 61 continues for a certain period of time, the duration of which is selected according to the quality requirements for surfaces of machined parts. At the end of the part processing operation, the coiler is rotated in the opposite direction and the abrasive material supply from the nozzle 63 is stopped. The machined parts are removed from the tumbling drum 61 to the conveyor 64 via the loading chute 65. Such a shot-blasting finishing device is a tumbling or conveyor type device however, in the proposed complex finishing installation, a carousel-type shot blasting finishing device may be used, the construction of which uses a step ovorotny table shown in Figure 10, a stepping turntable 66 is provided with a plurality of holders 67 and 68, etc., each of which is rotatable about a vertical axis. The holders 69 are evenly spaced around the circumference of the turntable 66 with equal angular spacing from one another. The holders 69 with the parts fastened therein while rotating the turntable 66 move in a circle alternately, passing through the positions

denoted by reference numeral 70, where the details are shot blasted. With further rotation of the turntable 66, the machined parts from position 70 are set to

positions indicated by reference numeral 71, where the parts are blown with a stream of compressed air for cleaning purposes.

The machined parts are conveyed by a conveyor 64 to the vibrating drum 72

finish car. Unlike conventional vibrating machines, the drum 72 of the vibrating machine under consideration has a toroidal shape and is mounted on a set located underneath

springs. Below the drum 72 is placed a vibrator or vibration motor, which creates the required vibration of the drum. In addition to the workpieces, a paste-like material, which is a mixture of abrasive material and diluent, is also loaded into the drum 72. The abrasive paste-like material in the vibrating drum performs a circular motion, thanks to the interaction between the machined

parts and abrasive materials the surface of the parts is subjected to the required finishing. Zibrogaltovka provides an additional improvement in the quality of the surfaces of the parts after they

shot blasting. Upon completion of the vibrating operation, the workpieces from the vibratory drum 72 are transferred to a screen separator 73, in which the parts are freed from abrasive residues. From the separator 73, through the output tray 74, the workpieces get into a transport container (not shown in Fig.), Which is lowered by a lift 75 onto the pick-up table 76, from which

parts are transported further to the place of their further processing. In the considered vibratory dimming machine, the lift 75 and the pick-up table 76 are essentially the same as the lift described previously

59 and the dispenser stolz 56 and therefore in their detailed description is not necessary.

The feeder 77 is also included in the design of the vibrating machine, for supplying a suitable diluent to the vibratory drum during the machine cycle. The same feeder can be used to supply flushing water to the vibratory drum after each cycle of

working parts to clean the inner surfaces of the drum. Flushing Abr

Rinsing of the workpieces with water is carried out in position 83, and anticorrosion treatment in position 84, and in these

In 5 positions, no electric current flows through electrode 93.

Thus, as a result of sequentially performed operations of electrochemical treatment, washing with water and

0 anti-corrosion treatment, the workpiece is in the final position 95, from where it is transferred to the second step conveyor 96. From the step conveyor 96, the manipulator 97 sequentially transfers the workpieces to the drum of the gyroscopic finishing machine 98. If, after processing in the gyroscopic finishing machine, a change in orientation is required workpiece, in the design of the machine can be applied. special device 99 that produces the necessary change in the orientation of the parts. After the orienting device 99, the workpieces are sequentially mounted5 on the third conveyor 100.

The brush finishing machine of the complex finishing machine is designed to remove burrs from the workpiece created by the cutting tool or relatively large local burrs, and the elongated vibratory jacking machine is used to finish all surfaces of the parts. In combination, these two machines provide deburring and surface treatment of any parts, for example, gears made by powder metallurgy.

A description of the operation of the integrated finishing installation shown in Fig. 15 is carried out in the sequence corresponding to the location of its interconnected working elements and assemblies. The part located on the conveyor 103 is first mounted in the first brush device 104, where the part is machined on one side only. The workpiece is then turned by the reversing mechanism 105 and turned into the second brush device 106, where it is machined from the opposite side. After brush finishing, the workpiece at the end of the conveyor 103 is grabbed by the first manipulator 107, which places it in the elongated vibro-damping machine 108. The elongated vibro-damping machine includes an elongated tumbling container that makes oscillatory motions created by two vibration generators located below, or vibration motors mi 109 and 110. The abrasive material and workpieces located in the dry container have a circular motion, during which aziv- ny material acts on workpieces carried finishing of their surfaces. At the exit from the oblong tumbling conveyor, the abrasive material and the workpieces get into a screen separator 111, which separates the parts from the abrasive material, The abrasive material, passing through the separator sieve, enters a special receiver for reuse, From the separator 112, the workpieces are processed through the gutter are transported to the position 113 where they are captured by the second manipulator 114, transferring them to the transport container on the pickup table 115. The manipulator 114 stacks the processed e details in the shipping container in a certain order. Upon filling the transport container, it is conveyor
