Abstract
The utility model discloses a machining arrangement, in particular a special milling machine for processing upper lockpins of railway wagon couplers. The milling machines consists of a motor, a gear box, a feeding device, a control part and guide rails, wherein a clamping device and two positioning pins are arranged on the feeding device; the bit of the clamping device is similar to the upper lockpin in shape; the clamping device and the positioning pins accurately and firmly position a work piece.; the main shaft of the gear box has a special mill; the guide rails below the mill are provided with a limiting block. In processing, when the feeding device hits the limiting block both transversally and longitudinally, the work will stop, i.e. the processing of a qualified work piece is ended. Used for processing soldering pieces of upper lockpins, the utility model provides great convenience, improving the production efficiency and accuracy and solving the noise and dust problems of prior grinding process with emery wheel machines.
Description
Technical field
The utility model relates to a kind of machining equipment, refers in particular to a kind of production miller of processing lock pin on the railway freight-car coupler.
Background technology
Lock pin is the vital part that connects the boxcar on the railway freight-car coupler, and it is very easy to wearing and tearing, and every use a period of time just needs to go up lock pin and pulls down, and with the abrading section repair welding, is worked into the size of drawing requirement then.Find to polish this mode with abrasive machine after each enterprise all adopts built-up welding at present through investigation.Part is constantly beated during polishing, and noise is very big, and dust four is penetrated, and labour intensity is big, and environment is abominable, is easy to the accident of damaging; Processing dimension is not easy to reach drawing requirement, inefficiency simultaneously.
Summary of the invention
At the shortcoming that exists in the lock pin repair welding process on the railway freight-car coupler, the purpose of this utility model provides lock pin processing production miller on a kind of railway freight-car coupler.
The utility model is achieved in that and comprises motor, gearbox, electric appliance control box, lathe bed, guide rail, feed arrangement, leading screw and speed regulating control case, output main shaft on the gearbox is positioned at guide rail left end top, and it is parallel in guide rail, feed arrangement is installed on the guide rail and matches with the traverse feed leading screw of guide rail below, a clamping device and two alignment pins above the feed arrangement, alignment pin is positioned at the appropriate location in clamping device left side, on the output main shaft, a special-purpose milling cutter is installed, on the appropriate location of the guide rail below the milling cutter, is fixed a limited block.
The jaw of described clamping device be with hitch on the shape that matches of lock pin profile.
The utility model has been obtained obvious effects after implementing, and stable processing quality is reliable, reaches the drawing requirement fully.Because clamping device is reasonable in design, it is very easy to be installed, and only needs last lock pin to be processed is put on the jaw and alignment pin of clamping device, tightens clamping device and gets final product; In addition since designed special-purpose milling cutter with and the guide rail of below on limited block, after workpiece installs, start feed arrangement, make workpiece move left to milling cutter and limited block place, rotate the length feed handle on the feed arrangement then, the beginning Milling Process, when length feed arrived limited block, workpiece just reached the process requirement, so a workpiece only need be processed once and can finish, do not need manual measurement, save the production time, improved operating efficiency, also reduced working strength of workers, and do not have dust and noise, purified working environment.The jaw of clamping device of the present utility model makes the shape with last lock pin appearance similar, help workpiece and clamp, avoid workpiece to move forward and backward or beat, set pin sleeve can prevent the rotation of workpiece in the hole of workpiece, therefore the back workpiece that is installed is firmly stable, has improved to be installed and process velocity.This milling machine is since using, and going up lock pins to 20,000, to have carried out processing effect fine.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.Wherein 1, electric control cabinet, 2, special-purpose milling cutter, 3, limited block, 4, guide rail, 5, alignment pin, 6, clamping device, 7, feed arrangement, 8, leading screw, 9, the feeding control cabinet, 10, gearbox.
The specific embodiment
The utility model comprises motor, gearbox, electric control cabinet, feed arrangement, the feeding control cabinet, lathe bed, guide rail, leading screw, motor places the lathe bed back, by belt power is passed to gearbox 10, gearbox 10 has gear drive with feeding control cabinet 9, thereby drive leading screw 8 and feed arrangement 7 rotations and mobile, feed arrangement 7 is installed on the guide rail 4 of lathe bed, top installation one clamping device 6 and two alignment pins 5 of feed arrangement 7, alignment pin 5 is installed in the appropriate location on the left side of clamping device 6, gearbox 10 is installed in the top, left side of guide rail 4, its output main shaft is parallel with guide rail 4, on its output main shaft a special-purpose milling cutter 2 is installed, a limited block 3 is installed in the appropriate location on the rear rail 4 below milling cutter 2.
Clamping device 6 of the present utility model is to be converted by vice, and its jaw is made the shape with last lock pin appearance similar, and firm being fixed on the feed arrangement of last lock pin that will process together of clamping device and alignment pin like this can not rotate or beat.
Claims (2)
1, lock pin production miller on the railway freight-car coupler, comprise motor, gearbox, electric appliance control box, lathe bed, guide rail, feed arrangement, leading screw and speed regulating control case, it is characterized in that: the output main shaft on the gearbox is positioned at guide rail left end top, and it is parallel in guide rail, feed arrangement is installed on the guide rail and matches with the traverse feed leading screw of guide rail below, a clamping device and two alignment pins above the feed arrangement, alignment pin is positioned at the appropriate location in clamping device left side, on the output main shaft, a special-purpose milling cutter is installed, on the appropriate location of the guide rail below the milling cutter, is fixed a limited block.
