Description

Technical Field

[0001] This invention relates to the field of elevator safety component processing equipment technology, and in particular to a precision iron cutting device for the claws of a straight elevator fall arrestor. Background Technology

[0002] The elevator fall arrestor is a key component of the elevator safety system. Its function is to bring the elevator car to an emergency stop when the elevator overspeeds or falls, by wedging the claws against the guide rails, thereby ensuring passenger safety. As the core actuator of the fall arrestor, the machining precision of the claws directly affects the fall arrestor's response speed, braking force, and operational reliability.

[0003] Currently, the machining of chucks is generally performed using general-purpose milling machines with simple fixtures. During operation, operators must manually clamp the chuck blank to be machined onto the worktable, adjust the clamping position, and start the machining process. After machining, the finished product is manually disassembled. Throughout the manual loading and unloading process, operators frequently need to pick up and place workpieces, with their hands close to the machining area, posing a significant safety hazard. Prolonged handling and clamping can easily lead to worker fatigue. Furthermore, the existing machining method makes continuous automated production difficult; after machining each chuck, the machine must be stopped for loading and unloading, resulting in low equipment utilization and significantly increasing the workload and reducing efficiency.

Detailed Implementation

[0025] To make the above-mentioned objects, features and advantages of the present invention more readily understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0028] Example 1 Reference Figure 1-6 As shown, this is the first embodiment of the present invention. This embodiment provides a precision iron-cutting machining device for the claws of a straight ladder fall arrestor, including a worktable 100 and an iron-cutting part 200, the iron-cutting part 200 being disposed above the worktable 100, and further including: The jaw clamping and positioning assembly 300 is disposed on the worktable 100 and is used to clamp and fix the jaws. The jaw clamping adjustment component 400 is connected to the jaw clamping positioning component 300 and is used to adjust the clamping position of the jaw clamping positioning component 300. The chuck loading assembly 500 is set on the worktable 100 and is used to transport the chuck to be processed to the processing station. The jaw support assembly 600 is disposed on the worktable 100 and located below the jaw, and is used to provide support for the jaw during the cutting process; The chuck lifting assembly 700 is disposed on the worktable 100 and is used to lift the chuck to be processed to the top of the worktable 100.

[0029] Specifically, in use, first, adjust the clamping position of the jaw clamping and positioning component 300 according to the specifications and dimensions of the jaws to be processed. Then, stack several jaws to be processed on the loading station of the jaw loading component 500. Next, start the jaw loading component 500 to transport the jaw blanks stacked on the loading station one by one to the preset station. After the jaws arrive at the station, start the jaw lifting component 700 to extend the jaw lifting component 700 upward, thereby pressing the jaw support component 600 with the jaw lifting component 700, causing the jaw support component 600 to retract. At the same time, the jaw lifting component 700 and the jaw support component 600... When the chuck is in contact with the workpiece, it is lifted upwards to the upper surface of the worktable 100. Then, the chuck clamping adjustment component 400 is activated, so that the chuck clamping positioning component 300 clamps and fixes the chuck under the action of the chuck clamping adjustment component 400. Then, the cutting component 200 is activated to perform precision cutting on the working surface and mounting hole of the chuck according to the preset processing program. After the processing is completed, the chuck clamping positioning component 300 releases the fixation on the chuck, and then the chuck lifting component 700 is reset, so that the processed chuck is placed on the corresponding station, and then the next processing cycle begins.

[0030] In summary, the chuck loading component 500 enables automatic and continuous loading of chucks to be processed. Combined with the chuck clamping and positioning component 300 and the chuck clamping adjustment component 400, it allows for rapid and precise automatic clamping and positioning of chucks of different specifications, avoiding repeated manual alignment and effectively ensuring consistent processing accuracy. It also significantly shortens auxiliary clamping time and improves processing efficiency. Furthermore, the coordinated operation of the chuck lifting component 700 and the chuck support component 600 allows the chuck lifting component 700 to better support and transport the chucks. Simultaneously, the chuck support component 600 can retract under the pressure of the chuck lifting component 700, preventing interference between the chuck lifting component 700 and the chuck support component 600 during operation.

[0031] like Figure 2 As shown, in a preferred embodiment, the worktable 100 has a through groove 110 extending along its length, and sliding grooves 120 are provided on both sides of the through groove 110. The sliding grooves 120 are used to guide the displacement of the chuck clamping adjustment assembly 400.

[0032] like Figure 3 As shown, in a preferred embodiment, the chuck clamping and positioning assembly 300 includes two slide rods 310, both of which are vertically and slidably disposed in corresponding slide grooves 120. Each slide rod 310 has a horizontally disposed adjusting screw 320 threadedly connected to its top end, and each of the two adjusting screws 320 has a clamping seat 330 that can slide on the upper surface of the worktable 100 installed at its adjacent ends.

[0033] Specifically, the operator can rotate the adjusting screw 320 to move the adjusting screw 320 in the horizontal direction relative to the slide bar 310, thereby driving the clamping seat 330 to move in the horizontal direction and adjusting the initial distance between the two clamping seats 330 to accommodate chucks of different widths.

[0034] like Figure 3 As shown, in a preferred embodiment, the chuck clamping adjustment assembly 400 includes a drive motor 410 and a mounting base 450. The drive motor 410 is vertically mounted on the bottom inner side of the worktable 100. A drive gear 420 is fixedly sleeved on the top of the output shaft of the drive motor 410. The mounting base 450 is fixedly mounted on the top inner side of the worktable 100. An adjustment seat 440 is rotatably mounted on the mounting base 450. A driven gear 430 is fixedly sleeved on the outer surface of the adjustment seat 440, and the driven gear 430 meshes with the drive gear 420. A through hole 441 is opened on the top axis of the adjustment seat 440, which is coaxially distributed with the through groove 110.

[0035] The top of the adjusting seat 440 has two arc-shaped displacement adjusting grooves 442, and the two displacement adjusting grooves 442 slide in cooperation with the corresponding slide rods 310. The two displacement adjusting grooves 442 are symmetrically arranged through the through hole 441.

[0036] Specifically, when the drive motor 410 starts, its output shaft drives the drive gear 420 to rotate. The drive gear 420 drives the adjusting seat 440 to rotate on the mounting seat 450 through the driven gear 430. When the adjusting seat 440 rotates, the slide rod 310 slides along the arc-shaped displacement adjusting groove 442. Since the displacement adjusting groove 442 has an axisymmetric arc structure, the two slide rods 310 are driven synchronously and move towards or away from each other along the sliding groove 120. The slide rods 310 then drive the clamping seat 330 to move synchronously through the adjusting screw 320, thereby clamping or releasing the claws located between the two clamping seats 330.

[0037] like Figure 4 As shown, in a preferred embodiment, the chuck loading assembly 500 includes two sets of mounting brackets 510. One set of mounting brackets 510 is horizontally mounted on the outer wall of the workbench 100, and the other set of mounting brackets 510 is horizontally mounted on the inner wall of the workbench 100. Two transmission pulleys 530 are fixedly sleeved on the outer surface of the rotating shaft rotatably mounted on the inner side of the mounting bracket 510, and the two transmission pulleys 530 on the same side are connected by the same conveyor belt 540. A horizontally arranged drive motor 520 is mounted on the side wall of the mounting bracket 510 located on the inner side of the workbench 100, and the output shaft of the drive motor 520 is connected to the rotating shaft on the mounting bracket 510.

[0038] The chuck loading assembly 500 also includes a loading frame 580, a guide rail 550, and several cross seats 560. The loading frame 580 is vertically mounted on the top of the mounting frame 510 located outside the workbench 100. There are two guide rails 550, which are respectively mounted on both sides of the two mounting frames 510. Several cross seats 560 are horizontally and equidistantly mounted on the outer surface of the two conveyor belts 540. Each cross seat 560 has a slip ring 570 at both ends that can slide along the guide rail 550.

[0039] Specifically, after the drive motor 520 starts, it drives the two transmission pulleys 530 on the same side to rotate synchronously through the rotating shaft. The transmission pulleys 530 drive the conveyor belt 540 to run. The conveyor belt 540 has a ring structure, and multiple cross seats 560 are fixed at equal intervals on its outer surface. The two ends of the cross seats 560 are slidably engaged with the guide rail 550 through slip rings 570, which ensures that the cross seats 560 move stably along the preset trajectory under the drive of the conveyor belt 540. The bottom of the loading frame 580 has an open structure, and multiple claws to be processed are stacked inside.

[0040] like Figure 6 As shown in the preferred embodiment, the claw support assembly 600 includes several baffles 630, each baffle 630 is horizontally mounted on a corresponding cross seat 560, and when the baffle 630 is at the top, its upper end face is flush with the lower end face of the feeding frame 580. Each baffle 630 has two sets of oppositely arranged mounting grooves 631 on its lower end face, and each mounting groove 631 has a spring 620 installed inside, and the two sets of sliding grooves 120 are slidably fitted with support rods 610 that move in opposite directions, and the ends of the support rods 610 are fixedly connected to the springs 620.

[0041] Specifically, the thickness of the baffle 630 is equal to the thickness of the gripper. Each horizontal seat 560 is fixed with a baffle 630. The baffle 630 moves synchronously with the horizontal seat 560. When the baffle 630 moves to the bottom of the feeding frame 580, the baffle 630 blocks the bottom of the feeding frame 580. When the upper surface of the baffle 630 leaves the bottom opening of the feeding frame 580, the gripper inside the feeding frame 580 falls onto the support rod 610, thereby allowing the support rod 610 to convey the gripper.

[0042] like Figure 5 As shown, in a preferred embodiment, the claw lifting assembly 700 includes a cylinder 710, which is vertically installed at the bottom of the inner side of the worktable 100 and is located directly below the through groove 110. A horizontally arranged top plate 720 is installed at the top telescopic end of the cylinder 710. The upper and lower surfaces of the top plate 720 are provided with adjusting grooves 721 that can compress the support rod 610.

[0043] Specifically, when the cylinder 710 is started, its piston rod extends upward, causing the top plate 720 to rise vertically. During the rise of the top plate 720, the adjusting groove 721 on its upper end surface first contacts the ends of the two support rods 610. The inclined structure of the adjusting groove 721 generates a squeezing force on the ends of the support rods 610, pushing the two support rods 610 to move along the slide groove 120 into the baffle 630. The spring 620 is compressed. Then, the upper end surface of the top plate 720 contacts and lifts the chuck to be processed. The chuck to be processed is then lifted and passes through the through hole 441 and the through groove 110 in sequence to the upper end surface of the worktable 100.

[0044] like Figure 3 As shown, in a preferred embodiment, a vertically arranged receiving box 800 is installed on the inner side of the workbench 100, and the receiving box 800 is located directly below the mounting frame 510.

[0045] Specifically, it is used to collect the chuck jaws after processing.

[0046] The specific working principle is as follows: First, the operator adjusts the two adjusting screws 320 according to the width of the chuck to be processed, so that the initial distance between the two clamping seats 330 matches the width of the chuck. At the same time, multiple chucks to be processed are neatly stacked in the loading frame 580. Start drive motor 520, which drives conveyor belt 540 through transmission pulley 530. Horizontal seat 560 moves with conveyor belt 540, causing baffle 630 to move. When baffle 630 moves directly below loading frame 580, it blocks the bottom of loading frame 580. When the upper surface of baffle 630 detaches from the bottom opening of loading frame 580, the claws inside loading frame 580 fall onto support rod 610, allowing support rod 610 to transport the claws. When the claw to be processed reaches the processing station, drive motor 520 stops, and conveyor belt 540 stops running. Restart cylinder 710. When cylinder 710 starts, its piston rod extends upward, driving top plate 720 to rise vertically. During the rise of top plate 720, the adjusting groove 721 on its upper end surface first contacts the ends of the two support rods 610. The inclined structure of adjusting groove 721 generates a squeezing force on the ends of support rods 610, pushing the two support rods 610 to move along slide 120 into baffle 630. Spring 620 is compressed. Then, the upper end surface of top plate 720 contacts and lifts the chuck to be processed. The chuck to be processed is then lifted and passes through through hole 441 and through groove 110 in sequence to the upper end surface of worktable 100. Restart the drive motor 410, which drives the adjusting seat 440 to rotate through the driving gear 420 and the driven gear 430. The adjusting seat 440 drives the slide rod 310 to slide in opposite directions along the slide groove 120 through the displacement adjusting groove 442. The slide rod 310 drives the clamping seat 330 to move in opposite directions through the adjusting screw 320, so that the clamping seat 330 clamps and positions the pawl. At this time, the support rod 610 is reset under the elastic force of the spring 620. Restart the iron cutting part 200 to perform precision iron cutting on the chuck. After the chuck is finished, start the drive motor 410 in reverse. The drive motor 410 drives the adjusting seat 440 to rotate through the driving gear 420 and the driven gear 430. The adjusting seat 440 drives the slide rod 310 to slide in the reverse direction along the slide groove 120 through the displacement adjusting groove 442. The slide rod 310 drives the clamping seat 330 to move in the reverse direction through the adjusting screw 320, so that the clamping seat 330 releases the clamping and positioning of the chuck.

[0047] Restart cylinder 710, the piston rod of cylinder 710 retracts, and top plate 720 descends and resets, thereby causing top plate 720 to drive the machined chuck to descend and reset. During the descent of top plate 720, the adjusting groove 721 on its lower end face first contacts the ends of the two support rods 610. The inclined structure of adjusting groove 721 generates a squeezing force on the ends of support rods 610, pushing the two support rods 610 to move along slide 120 into baffle 630. Spring 620 is compressed. When adjusting groove 721 on the upper end face of top plate 720 contacts support rod 610, support rod 610 resets under the action of spring 620, thereby supporting the machined chuck. This process is repeated to realize continuous automated precision machining of chuck.
