Description

Technical Field

[0001] The invention belongs to the technical field of eyeglass plate processing, in particular to a flipper used for processing hard alloy eyeglass plates. Background Art

[0002] Carbide spectacle plates are made of carbide materials and are shaped like glasses, hence the name. This type of spectacle plate has extremely high hardness and wear resistance, and can withstand huge friction and impact during concrete pumping. The processing of carbide spectacle plates is mainly through a series of complex processing procedures, such as cutting, grinding, drilling, polishing, etc., so that the carbide material has a specific shape, size and precision requirements.

[0003] In the process of processing the cemented carbide eyeglass plate, it is necessary to set a clamp at both ends of the eyeglass plate to fix it to ensure the processing stability and avoid affecting the processing accuracy due to the offset of the plate position. Due to the different production specifications of different types of eyeglass plates, it is necessary to frequently adjust the distance between the two sets of clamps to adapt to eyeglass plates of different lengths. In the prior art, the adjustment process of the clamp is relatively troublesome: when one side of the eyeglass plate is processed, the operator needs to first release it and turn it over so that the other side faces up, and then fix the eyeglass plate again to process the other side of the eyeglass plate. The entire processing process requires manual disassembly and assembly of the clamp and repeated rotation of the bolt or threaded rod. When replacing the eyeglass plate of other lengths, it is also necessary to rotate the bolt or threaded rod to adjust the clamp spacing. The process is very cumbersome, not only inefficient, but also wastes a lot of time and is extremely labor-intensive. In addition, the existing processing equipment does not support the support foot to adjust the height separately. When the factory has the problem of uneven ground, it may cause the equipment placed on it to tilt as a whole, and then cause the processing reference surface to tilt, seriously affecting the normal processing operation of the eyeglass plate.

[0004] Therefore, the industry needs a new tool for processing cemented carbide eyeglass plates. Summary of the invention

[0033] The fixing mechanism 3 comprises a connecting block 301, a pull rod 302, a connecting rod 303, a moving rod 304 and a clamping block A 305, all of which are horizontally arranged. The connecting block 301 is hollow inside, the pull rod 302 is slidably penetrated through the front side wall of the connecting block 301, there are two moving rods 304, both of which are slidably penetrated through the rear side wall of the connecting block 301, the sliding directions of the moving rod 304 and the pull rod 302 are perpendicular to each other, there are two connecting rods 303, which are symmetrically arranged inside the connecting block 301, one end of the connecting rod 303 is hinged to one end of the pull rod 302 located inside the connecting block 301, and the other end is hinged to one end of the corresponding moving rod 304 located inside the connecting block 301, and the clamping block A 305 is fixedly connected to one end of the moving rod 304 located outside the connecting block 301, and the two clamping blocks A 305 are driven to move closer to or away from each other through the pull rod 302.

[0034] The clamp block A 305 is hollow inside and a clamp block B 307 is hinged on the top. The two clamp blocks A 305 and the two clamp blocks B 307 cooperate to form two clamping grooves with opposite notches, which are used to fix the eyeglass plate body 6. The outer wall of the clamp block A 305 is provided with a slot 306, and the clamp block B 307 is provided with a retractable protrusion 309 at the position corresponding to the slot 306. Specifically, the clamp block B 307 is slotted at the position corresponding to the slot 306, and a connecting spring 308 is provided in the slot body, one end of the connecting spring 308 is fixedly connected to the inner wall of the slot body and the other end is fixedly connected to the protrusion 309. The connecting spring 308 is configured so that the protrusion 309 is inserted into the slot 306 when it is naturally extended, and the clamping groove is clamped and loosened on the eyeglass plate body 6 through the cooperation of the protrusion 309 and the slot 306.

[0035] A plurality of grooves 310 arranged along the axial direction are provided on the top of the pull rod 302, and the specific positions of the grooves 310 are set to match the eyeglass plate bodies 6 of different lengths. A fixing block 311 is fixedly connected to the upper surface of the connecting block 301, and a clamping block 313 is inserted through the inside of the fixing block 311. A return spring 312 is connected between the clamping block 313 and the inner wall of the fixing block 311, and the return spring 312 is set so that the insertion end of the clamping block 313 is inserted into the groove 310 when it is naturally extended.

The purpose of the above structural design is to facilitate operation. For example, when the pull rod 302 is pulled outward to drive the two clamping blocks A 305 to approach each other, the groove 310 contacts and squeezes the inclined surface of the insertion end of the card block 313, so that the card block 313 moves upward and disengages from the groove 310. The whole process does not require the worker to manually lift the card block 313, and will not affect the pulling of the pull rod 302 outward. Similarly, when it is necessary to clamp the eyeglass plate body 6, the clamping block B 307 is closed, and the side wall of the clamping block A 305 contacts and squeezes the arc surface of the insertion end of the protrusion 309, so that the protrusion 309 retracts until the protrusion 309 moves to the position of the card slot 306 to complete the clamping. The whole process does not require the worker to manually press the protrusion 309 to keep it in a retracted state, and the clamping block B 307 only needs to be directly closed.

[0037] In this embodiment, two protrusions 309 are symmetrically arranged on each clamping block B 307, and the two protrusions 309 slide in opposite directions at the same time.

[0038] In this embodiment, a handle is provided at the non-insertion end of the clamping block 313, and a pull handle is provided at one end of the pull rod 302 located outside the connecting block 301, and the axial cross-sections of the handle and the pull handle are both T-shaped.

[0039] The flip mechanism 4 includes a fixed rod 401 and a rotating shaft 402, both of which are horizontally arranged. One end of the fixed rod 401 is connected to the front side wall of the connecting block 301 and the other end is connected to one end of the rotating shaft 402. The rotating shaft 402 is rotatably connected to the fixed plate 2. The rotating shaft 402 passes through the fixed plate 2 and is connected to a rotating block 409 at the other end. A handle 408 is connected to the rotating block 409 on the side away from the rotating shaft 402. A partition 407 is slidably connected to the handle 408. The rotating block 409 is hollow inside and is provided with a moving plate 403 and a telescopic spring 406. The moving plate 403 and the telescopic spring 406 are provided on the rotating block 409. A connecting column 410 is fixedly connected to one side of the plate 403 close to the handle 408, and the other end of the connecting column 410 passes through the rotating block 409 and is fixedly connected to the partition 407. The telescopic spring 406 is sleeved on the connecting column 410 and one end is fixedly connected to the inner wall of the rotating block 409 and the other end is fixedly connected to the movable plate 403. The movable plate 403 is fixedly connected to an insertion block 404 on the side away from the handle 408. A slot 405 is provided on the fixed plate 2 at the position corresponding to the insertion block 404, and the other end of the insertion block 404 passes through the rotating block 409 and is engaged with the slot 405.

[0040] In this embodiment, there are two plug blocks 404, which are symmetrically arranged at an interval of 180° on the upper and lower sides of the rotating shaft 402. In other embodiments, more plug blocks 404 can also be arranged, as long as the position distribution of all plug blocks 404 is symmetrical about the center of the rotating shaft 402, that is, they can still be connected to the slots 405 one by one after rotating 180°.

[0041] The adjusting mechanism 5 includes a vertically arranged supporting leg 501, the upper end of which is fixedly connected to the lower surface of the workbench 1, the lower end of which is grooved and a vertical threaded rod 502 is arranged in the groove body, the upper end of which is fixedly connected to the inner wall of the groove body and a slider 507 is arranged at the lower end, the lower surface of which is fixedly connected to a base 506, a threaded hole is arranged on the upper surface of the slider 507 and is threadedly connected to the threaded rod 502, guide blocks are also arranged at both ends of the slider 507, the guide blocks are slidably connected to the inner wall of the groove body, so that the slider 507 can move up and down in the groove body, a bevel gear B 505 is fixedly sleeved on the threaded rod 502, a bevel gear A 504 is arranged on the inner wall of the groove body, and the bevel gear A 504 is meshed with the bevel gear B 505, a rotating handle 503 is arranged on the outer wall of the supporting leg 501, and the transmission shaft of the rotating handle 503 penetrates into the interior of the groove body and is connected to the bevel gear A 504 is fixedly connected, and the slider 507 is moved up and down relative to the support leg 501 through the handle 503, thereby adjusting the height between the base 506 and the workbench 1.

[0042] The working process of the flipper used for processing cemented carbide eyeglass plates in this embodiment is as follows:

[0043] Before clamping and fixing the eyeglass plate main body 6, it is necessary to adjust the distance between the two groups of clamping blocks A 305. When the length of the eyeglass plate main body 6 is long, the pull rod 302 needs to be pushed into the connecting block 301. At this time, the block 313 can be lifted up to disengage from the groove 310 to release the limit of the pull rod 302. When the length of the eyeglass plate main body 6 is short, the pull rod 302 needs to be pulled outward from the connecting block 301. Since the inner wall of the groove 310 squeezes the inclined surface below the block 313 during pulling, the block 313 moves upward. Therefore, there is no need to lift the block 313 manually, and the pulling of the pull rod 302 outward is not affected. When the pull rod 302 moves, it will drive the two moving rods 304 to move toward the middle or both sides at the same time through the two connecting rods 303, thereby driving the two clamping blocks A 305 to move closer or farther away from each other to adapt to eyeglass plate main bodies 6 of different lengths. When the clamping blocks 305 move to a suitable distance, the clamping block 313 pops up downward under the action of the return spring 312 and engages with a corresponding groove 310. At this time, the movement of the pull rod 302 is restricted and the positions of the two clamping blocks A 305 are fixed.

[0044] When the eyeglass plate main body 6 is clamped and fixed, the eyeglass plate main body 6 can be placed on the clamp block A305, and the clamp block B307 is closed to cover the top of the eyeglass plate main body 6. In the process of covering the clamp block B307, the arc surface on the lower surface of the protrusion 309 is squeezed by the outer wall of the clamp block A305 and moves into the groove body inside the clamp block B307. The connecting spring 308 is forced to shrink until the clamp block B307 is flipped over to contact the upper surface of the eyeglass plate main body 6. The protrusion 309 corresponds to the position of the card slot 306 and pops outward under the elastic force of the connecting spring 308. The protrusion 309 is clamped with the card slot 306, thereby completing the limitation of the clamp block B307. At this time, the clamp block B307 cooperates with the clamp block A305 to realize the rapid clamping and fixing of the eyeglass plate main body 6. Even if the eyeglass plate main body 6 is flipped over, it will not fall off.

[0045] When one side of the spectacle plate body 6 is processed and needs to be turned over, the operator holds the handle 408 and pulls the partition 407, and drives the movable plate 403 and the plug block 404 to retract synchronously through the partition 407, so that the plug block 404 is out of contact with the slot 405, and the limit of the rotating block 409 can be released, and then the handle 408 is turned to drive the rotating block 409, the rotating shaft 402 and the fixing rod 401 to rotate synchronously, and then drive the fixing mechanism 3 to turn over as a whole, and turn the spectacle plate body 6 to the other side facing up, and finally release the partition 407, under the action of the telescopic spring 406, the movable plate 403 drives the plug block 404 to pop out, and the plug block 404 is again engaged with the slot 405, and the flipping mechanism 4 and the fixing mechanism 3 are fixed again. At this time, the spectacle plate body 6 is in a stable processing state, and the processing operation can be performed on its flipping surface. The whole flipping process is simple and easy, and compared with the traditional method that requires the spectacle plate body 6 to be released and removed and then re-clamped before processing, the work efficiency is greatly improved.

[0046] After the processing of the eyeglass plate body 6 is completed, the protrusions 309 on both sides of the clamp block B 307 can be pressed simultaneously to make the protrusions 309 disengage from the slots 306, and the limit of the clamp block B 307 is released to flip it upwards, and the eyeglass plate body 6 can be directly removed.

[0047] When the ground is uneven and the workbench 1 is not in a horizontal state, the operator finds the adjustment mechanism 5 in the area that is too high or too low, and drives the bevel gear A 504 to rotate by rotating the handle 503, and then drives the bevel gear B 505 meshing with the bevel gear A 504 to rotate, so that the threaded rod 502 fixedly connected to the bevel gear B 505 rotates synchronously, and the threaded rod 502 drives the slider 507 and the base 506 to move upward or downward synchronously to adjust the combined length of the support leg 501 and the base 506. By setting the adjustment mechanism 5, it is ensured that the workbench 1 is always in a horizontal state, not affected by the uneven ground, and the processing accuracy of the eyeglass plate body 6 is guaranteed.
