Described welding post 4 includes the rotating seat 41 being fixed on mainframe 1 and some the welding rifles 42 being arranged on its periphery, and welding rifle 42 is connected with rotating seat 41 by position regulator;
Described positional stations 5 includes the location slide unit 51 being fixedly mounted on mainframe 1, the top of location slide unit sets servo drive 52 for controlling the height of location slide unit 51, the lower end of location slide unit 51 is provided with location pressure head 53, and location pressure head 53 is pressed against on compressor body 8 to its location;
Described lifting station 6 includes the lifting slide unit 61 being arranged on mainframe, and lifting slide unit 61 promotes flowing water station 3 to move upward under the effect of lifting driving device, enters in welding post 4;
Described quality inspection station 7 includes the welding quality inspection device 71 being arranged on streamline slideway 2 side, and welding quality inspection device 71 is arranged in frame 1 by retractor device 72.
Described positioning seat 32 is arranged on slide plate 31 by rotating lifting device 33.
Described welding rifle 42 is provided with three, is evenly distributed on rotating seat 41 peripheral.
Described position regulator is the radiai adjustment seat 43 being fixed on outside rotating seat 41, and radiai adjustment seat is provided with axial adjustment seat 45 by radial direction slide rail 44, and described welding rifle 42 is arranged in axial adjustment seat 45 by angular adjustment seat 46.
It is provided with radial drive cylinder 47 between described radiai adjustment seat 43 and axial adjustment seat 45.
Described location pressure head 53 includes spring bearer plate 531 and rebound 532, is provided with pre-compressed spring 533 and position sensor 544 between spring bearer plate 531 and rebound 532, and rebound 532 fixedly mounts with location slide unit 51.
Described lifting driving device includes the lifting cylinder 62 and the lifting guide pillar 63 that are arranged between mainframe 1 and lifting slide unit 61.
Described retractor device 72 includes the axial stretching slide unit 721 being fixed on mainframe 1, axial stretching slide unit 721 is provided with radial expansion slide unit 722, welding quality inspection device 71 be arranged on the top of radial expansion slide unit 722, axial stretching slide unit 721 and radial expansion slide unit 722 be provided with driving cylinder 733 drive slide unit to move.
The described driving device 52 that takes is the servo drive motor 521 being arranged on mainframe 1, and servo drive motor 521 is connected with screw mandrel 522, and screw mandrel 522 is spirally connected 523 with the feed screw nut being located on the slide unit 51 of location.
Workflow: action 1: user adopts manually or compressor body is arranged in the positioning seat 32 on the work dish of location by automation equipment, owing to the structure in this case adopts pipeline system operation, therefore can be arranged in order by multiple location work dishes being provided with compression body is placed in streamline slideway simultaneously, by driving equipment, location work dish is pushed this welding equipment.
Action 2: location work dish 3 enters in lifting station, and lifting slide unit 61 moves upward, and sends in welding post 4 together with location work dish.Wherein lifting slide unit 61 can adopt lifting cylinder to drive, it is possible to adopts servo screw mandrel to drive.Therefore when producing the compressor of differing heights, it is only necessary to adjusted the movement travel of lifting cylinder by position-limit mechanism, or the control system driven by servo screw mandrel is carried out parameter and arranges.So that this equipment can produce the product of more polytypic, promote its scope of application.
Action 3: location pressure head, at the moved downward of location slide unit 51, promotes location pressure head to be pressed against on compressor body 8, plays the fixation to compressor body.Wherein location pressure head 53 includes spring bearer plate 531 and rebound 532, is provided with pre-compressed spring 533 and position sensor 544 between spring bearer plate 531 and rebound 532, and rebound 532 fixedly mounts with location slide unit 51.When positioning pressure head and touching compressor body, owing to the spring bearer plate 531 of its front end adopts spring supporting, so buffering can be played and compensates the effect of fit-up gap.Compressor body is caused to damage too greatly thus avoiding rigid positioner can produce location stroke.Or causing detent force inadequate because location stroke is too small, compressor body is susceptible to phenomenons such as loosening.After spring bearer plate 531 contacts with compressor body, meeting trigger position detector 544, provide welding operation signal to control system.
Action 4: the radial drive cylinder 47 driving axial adjustment seat 45 on position regulator is moved to compressor direction so that welding rifle arrives position while welding and welds.Rotating seat 41 can be adopted during welding to drive the mode of welding circular motion to weld.May be used without the mode that rotating lifting device 33 drives compressor body to rotate and carry out circumference soldering.Wherein it should be understood that owing to compressor body typically requires upper and lower twice weld seam, after therefore having welded second in this case, lifting station and positional stations move upward simultaneously so that second position while welding with weld rifle to it.When needing the compressor producing different model, it is only necessary to by adjusting the relevant stroke of retractor device 72.It addition, this case adopts the often welding simultaneously of three welding rifles, while promoting welding efficiency, compressor body thermally equivalent can be made, it is ensured that welding quality.Thus avoiding inefficiency during tradition single welding rifle operation, it is easy to uneven cause that compressor body easily produces thermal deformation because welding is heated, cause the drawbacks such as unstable product quality.
Action 5, welded after, lifting station, welding post, positional stations reset, and streamline driving device promotes location work dish entrance quality inspection station weld.Meanwhile, the next location work dish not welded enters into lifting station and welds, later reciprocation cycle like this.Enter the compressor of quality inspection station after the detection of weldquality detector, as fruit product is qualified, enter subsequent processing by streamline, if defective, by sound and light alarm, or discharging device such as is driven in waste material road to carry out artificial repair welding, scrap at the operation.Complete the automatic welding operation of a compressor, reciprocation cycle like this later to this, be specifically no longer described in detail.
With conventionally employed human weld, or the technology such as semi-automatic welding machine compares, the structure in this case just realizes the operations such as full automatic feeding, location, clamping, welding, quality inspection, while improving production efficiency, when avoiding artificial or semi-automatic operation, because welding causes the healthy infringement of workman.Additionally, lifting and positional stations in this case adopt servo structure to drive, therefore when producing the compressor body of different model, have only to carry out in the controls corresponding parameter setting, this equipment is made to realize changing product debugging speed fast, production efficiency advantages of higher, therefore use can be widely popularized.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.
