Abstract
The invention discloses a machining device for cleaning a rear axle half-shaft workpiece. A workbench is fixed to the upper portion of a rack. A left cam and a left ejector rod are both in key connection with a left rotary shaft. The left rotary shaft is rotationally connected to a left connecting lug plate. A right cam and a right ejector rod are both in key connection with a right rotary shaft. The right rotary shaft is rotationally connected to a right connecting lug plate. A left sliding way allowing the left ejector rod to slide vertically is formed in the upper portion of the rack. A left through hole located above the left sliding way is formed in the workbench. The lower end of the left sliding way can abut against the cam edge of the left cam. A right sliding way allowing the right ejector rod to slide vertically is formed in the upper portion of the rack. A right through hole located above the right sliding way is formed in the workbench. The lower end of the right sliding way can abut against the cam edge of the right cam. The left end of a connecting plate is hinged to the upper end of a left crankshaft, and the right end of the connecting plate is hinged to the upper end of a right crankshaft. According to the machining device, clamping and positioning of the workpiece can be achieved; the workpiece can be rapidly clamped; the efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of fixture, be specifically related to a kind of rear sedan-chair half shaft-like work cleaning processing unit (plant).
Background technology
Half gland retainer plate is the important guard member of on automobile axle, in the running of automobile, subjects the weight of whole vehicle body and vehicle-mounted cargo.Meanwhile, due to the change of road conditions, it also will bear the alternate stress of various complexity.Therefore, the quality of half gland retainer plate quality, directly has influence on the driving safety of vehicle.
In prior art, half gland retainer plate is generally forging and makes, and its surface can produce many burrs, needs to polish.Be generally that workman is fixed processing by hand-held, crudy is difficult to ensure, nor safety, efficiency is also low.
Summary of the invention
The invention is intended to provide a kind of rear sedan-chair half shaft-like work cleaning processing unit (plant), to improve working (machining) efficiency.
In base case: rear sedan-chair half shaft-like work cleaning processing unit (plant), comprise frame, also to comprise in frame from left and the workbench of right layout, left push rod, left cam, left rotary shaft, left crank, connecting plate, right crank, by motor-driven right spindle, right cam and right push rod; Workbench is fixed on upper rack, frame lower is provided with left connection otic placode, right connection otic placode, left cam, the equal key of left push rod are connected in left rotary shaft, left rotary shaft is rotatably connected on left connection otic placode, right cam, the equal key of right push rod are connected on right spindle, and right spindle is rotatably connected on right connection otic placode, and upper rack has the left slideway vertically slided for left push rod, workbench has the left through hole be positioned at above left slideway, left slideway lower end can offset with left cam wheel rim; Upper rack has the right slideway vertically slided for right push rod, and workbench has the right through hole be positioned at above right slideway, right slideway lower end can offset with right cam wheel rim; Connecting plate left end and left crank upper end thereof, connecting plate right-hand member and right crank upper end thereof.
Principle of the present invention: during use, workpiece is placed on workbench, control step motor drives right spindle to rotate forward, right crank and right cam rotate forward, and right push rod moves up top tight workpiece, meanwhile, right crank drives left crank to rotate forward by connecting plate, and then drive left cam to rotate forward by left rotary shaft, drive left push rod to move up, thus by workpiece pre-tightening together with right push rod; After machining, control step motor drives right spindle reversion, and right cam, left cam all reset, and right push rod, left push rod reset under workpiece Gravitative Loads, can unclamp workpiece.
The present invention can realize the clamping and positioning to workpiece, to workpiece quick-clamping, can substantially increase efficiency.
Preferred version one, based on the further optimization of scheme, described motor is stepper motor; Stepper motor runs more accurate, can be continuously applied pretightning force.
Preferred version two, the preferably further optimization of one, workbench is fixed by screws in upper rack and passes through finger setting with upper rack; Fast and easy location and installing/dismounting.
Preferred version three, the preferably further optimization of two, have the first gap mated with left rotary shaft in the middle part of connecting plate, frame lower has the second gap for left crank-swinging and the 3rd gap for right crank-swinging; Avoid connecting plate movement locus and left rotary shaft to interfere, the first gap can, when unclamping workpiece, be stuck in left rotary shaft simultaneously, and keep the stable of left crank, right crank, the second gap, the 3rd gap then can ensure the even running of this device.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: frame 10, workbench 11, connecting plate 20, left cam 21, left top-fastening rod 22.
Embodiment is substantially as shown in Figure 1: rear sedan-chair half shaft-like work cleaning processing unit (plant), comprise frame 10, also comprise in frame 10 from left and the workbench 11 of right layout, left push rod, left cam 21, left rotary shaft, left crank, connecting plate 20, right crank, right spindle driven by stepper motors, right cam and right push rod; Workbench 11 is fixed by screws in frame 10 top and passes through finger setting with frame 10 top, frame 10 bottom is provided with left connection otic placode, right connection otic placode, left cam 21, the equal key of left push rod are connected in left rotary shaft, left rotary shaft is rotatably connected on left connection otic placode, right cam, the equal key of right push rod are connected on right spindle, right spindle is rotatably connected on right connection otic placode, frame 10 top has the left slideway vertically slided for left push rod, workbench 11 has the left through hole be positioned at above left slideway, left slideway lower end can offset with left cam 21 wheel rim; Frame 10 top has the right slideway vertically slided for right push rod, and workbench 11 has the right through hole be positioned at above right slideway, right slideway lower end can offset with right cam wheel rim; Connecting plate 20 left end and left crank upper end thereof, connecting plate 20 right-hand member and right crank upper end thereof, have the first gap mated with left rotary shaft in the middle part of connecting plate 20, frame 10 bottom has the second gap for left crank-swinging and the 3rd gap for right crank-swinging.
Be one side two finger settings between workbench 11 and frame 10, axles and the holes (locating hole) of two pins are matched in clearance closely; One of them is straight pin, and another is rhombus pin, and locating hole centre-to-centre spacing exists tolerance (error), if two pins are all straight pins, then, two pins on fixture just can not coordinate with the holes of workpiece " accurately ", and dress is not entered.After one of them does diamondwise pin, locating hole centre-to-centre spacing error just can not interfere having coordinated of two pins and holes.Analyze from location, restraint of liberty degree, two straight pins were location.The major axis of rhombus pin, with two pin-and-hole lines of centres, must be vertical, otherwise just lose the effect of rhombus pin.
During use, workpiece is placed on workbench 11, control step motor drives right spindle to rotate forward, right crank and right cam rotate forward, and right push rod moves up top tight workpiece, meanwhile, right crank drives left crank to rotate forward by connecting plate 20, and then drive left cam 21 to rotate forward by left rotary shaft, drive left push rod to move up, thus by workpiece pre-tightening together with right push rod; After machining, control step motor drives right spindle reversion, and right cam, left cam 21 all reset, and right push rod, left push rod reset under workpiece Gravitative Loads, can unclamp workpiece.
