The clamping part has eight, and gasket is provided on the pedestal, and the alignment pin is fixedly connected on pedestal by gasket, institute
It states there are four alignment pins；First positioning pin and the second positioning pin are used to position the dowel hole on elevator brake block, institute
Mistake proofing pin is stated for positioning any bolt hole of elevator brake block upper bolt hole side conllinear with dowel hole；The clamping part packet
Gripper cylinder, gripper cylinder switch and grip block are included, the gripper cylinder switch is connected with gripper cylinder by pipeline, the folder
Block is held to be rotationally connected at the top of gripper cylinder；The middle of the base is fixedly connected with tension cylinder, the tension switching cylinder and
It tenses cylinder to connect by pipeline, slidably connects tie rod in the tension cylinder；The frock clamp further includes anticollison block,
The anticollison block is fixedly connected on briquetting bottom, and card slot is offered on the anticollison block, is provided with convex block at the top of the tie rod,
The tie rod is connected in the card slot of anticollison block by convex block；
Referring to attached drawing 3 and 4, which comprises
Step 1: while two elevator brake block top surfaces 601 are clamped in upwards on dual openings bench vice, and it is short to clamp two
Side；
Step 2: two elevator brake block top surfaces 601 are milled simultaneously with the first numerically-controlled machine tool, and carry out secondary fine milling；
Step 3: being machining benchmark with long side surface 603, mills four of two elevator brake blocks simultaneously with the first numerically-controlled machine tool
Dowel hole 602；
Step 4: four elevator brake block bottom surfaces 604 are placed on frock clamp as shown in Figure 5 simultaneously upwards, benefit
It is positioned with alignment pin, and presses two thin wings 606 that gripper cylinder switch makes grip block compress elevator brake block；
Step 5: being machining benchmark with elevator brake block top surface 601, mills four elevators simultaneously with two the second numerically-controlled machine tools
The bottom surface 604 of brake block and long side surface 603, and carry out secondary fine milling；
Step 6: it by briquetting by tensing cylinder-pressing in elevator brake block bottom surface 604, unclamps elevator brake block two thin
The wing 606, the short sides 605 of four elevator brake blocks are milled with two the second numerically-controlled machine tools simultaneously, and carry out secondary fine milling, and elevator is stopped
Vehicle piece completion of processing.
The efficiency of the processing scheme of embodiment three and example IV compares such as table 1.
Table 1
| Elevator brake block process | Embodiment three | Example IV |
| Step 1 to three processing | One 4 minutes | Two pieces 4 minutes |
| Step 3 is reloaded to four | One 10 seconds | Two pieces 10 seconds |
| Step 5 | Two pieces 8 minutes | Four 16 minutes |
| Step 5 compresses for the first time | Two pieces 10 seconds | Four 1 second |
| Second of compression of step 5 | Two pieces 20 seconds | Four 10 seconds |
| It reloads cleaning | Two pieces 10 seconds | Four 10 seconds |
By above table it should be apparent that example IV saves tool change time 40 seconds than embodiment three, account for about total
The 10% of process time；Example IV processing is clamped using cylinder, and 8, a cylinder of Air Valve Control 6 pushes, when saving clamping
Between about 20 seconds；By embodiment three, the dress briquetting of rotation screw rod and disassembly briquetting are changed to example IV cylinder behaviour manually when tooling is changed in pause
Make, saves the clamping time about 30 seconds；Bottom surface, which is processed, is changed to scheme 24 material by two material of scheme one, saves tool change time about
50 seconds；The tooling of example IV cylinder-pressing workpiece is more more firm than embodiment three, and process velocity improves 10% than embodiment three
Feeding is about raised speed 2 minutes；Material both wings edge can be avoided after example IV two sides lower air cylinder retraction, is added compared to embodiment three
The complete workpiece of work also needs to repair burr with deburring cutter manually, and burr has been repaired entirely in program, made outside workpiece by example IV tooling
It sees more attractive；The alignment pin of example IV keeps processing stations higher by the way that gasket is padded, and aluminium can be cut easily and be washed from by cutting fluid
Workpiece, reduction blow aluminium when reloading and cut the time；
It is compared by analysis above, with example IV comparative example three:
1. processing piece time only needs the 70% of embodiment three；Burr is repaired by hand 2. saving, keeps employee work more easily pleased
Fastly；3. saving positive refine cutter (reducing cutter is save the cost), the finish consistency that reverse side processes side is more preferable；
4. because not repair burr manually, an employee of embodiment three operates the scalable member for example IV of two numerically-controlled machine tools
Work operates three numerically-controlled machine tools, even if three numerically-controlled machine tools can stop two simultaneously when reloading, but the daily output can also promote 60%
More than, it greatly improves the efficiency.
In conclusion a kind of elevator brake plate machining device provided by the invention and processing method, beneficial effect are: making
The manufacturing procedure of elevator brake block is standardized, and batch production processing is convenient for；Step 1 to step 3 uses bench vice clamping,
And step 4 to step 6 uses frock clamp clamping, reduces clamping times, is conducive to assembly line processing, improves production effect
Rate；Other are avoided using two not high thin wings of elevator disc surface required precision as holding portion as far as possible in process
The higher face of required precision generates damage because of the effect of chucking power；The same elevator is processed respectively using two numerically-controlled machine tools
Brake block, it is possible to reduce tool change time；The alignment pin of frock clamp not only can guarantee the machining accuracy of elevator brake；Tooling folder
Tool is capable of the different location of clamping elevator brake block and is processed respectively to different surfaces, and the utilization rate of frock clamp is improved
With worker's working efficiency, complicated replacement fixture operation is avoided；Frock clamp two elevator brake blocks of clamping can go forward side by side simultaneously
Row processing；It two elevator brake block blanks of clamping and can be processed simultaneously using dual openings bench vice, reduce machining period,
Improve working efficiency.
