[0035] Example:

[0036] See also Figure 1-4 A fixing device for processing a mounting plate comprises a fixing seat 1, to which a fixing plate 2 is fixedly connected, to which a top plate 3 and two positioning plates 4 are slidably connected, and the top plate 3 corresponds to the fixing plate 2, a pushing mechanism is arranged between the fixing seat 1 and the top plate 3, the pushing mechanism is used to push the top plate 3 to move and cooperate with the fixing plate 2 to fix the mounting plate, a synchronization mechanism is arranged between the fixing seat 1 and the two positioning plates 4, the synchronization mechanism is used to control the two positioning plates 4 to move simultaneously to position the mounting plate, a clamping mechanism is arranged on the fixing plate 2, the clamping mechanism is used to clamp and fix the mounting plate, an auxiliary mechanism is arranged on the top plate 3, the auxiliary mechanism cooperates with the clamping mechanism to clamp and fix the mounting plate, and a distance adjusting mechanism is arranged on the two positioning plates 4, the distance adjusting mechanism enables the two positioning plates 4 to position mounting plates of different sizes.

[0037] In this embodiment, when the mounting plate needs to be fixed during processing, the mounting plate is placed on the fixing seat 1, and the pushing mechanism pushes the clamping plate 3. The clamping plate 3 cooperates with the fixing plate 2 to clamp and fix the mounting plate. At the same time, the synchronization mechanism pushes the two positioning plates 4. The two positioning plates 4 position the mounting plate through the distance adjustment mechanism, so that the mounting plate is moved to the middle of the fixing seat 1 to correspond to the processing equipment. In the process of the clamping plate 3 cooperating with the fixing plate 2 to clamp the mounting plate, the auxiliary mechanism cooperates with the clamping mechanism to clamp and fix the mounting plate, so that the mounting plate further maintains stability.

[0038] Specifically, the pushing mechanism includes a first placement cavity 501, which is excavated in the fixing seat 1, a threaded rod 502 is rotatably connected in the first placement cavity 501, a first nut 503 is threadedly connected to the circumferential surface of the threaded rod 502, a first slideway 504 is excavated on the fixing seat 1, and the first slideway 504 is connected to the first placement cavity 501, a first slider 505 is fixedly connected to the first nut 503, and the first slider 505 is movable through the first slideway 504 and is fixedly connected to the bottom end of the tightening plate 3.

[0039] In this embodiment, when fixing the mounting plate, the first nut 503 is moved in the first placement cavity 501 by rotating the threaded rod 502 in the first placement cavity 501, and the first nut 503 drives the first slider 505 to slide in the first slideway 504, thereby moving the clamping plate 3. The movement of the clamping plate 3 and the fixing plate 2 can clamp the mounting plate on the fixing seat 1.

[0040] Specifically, the synchronization mechanism includes a second placement cavity 601, in which a bidirectional screw 602 is rotatably connected, and a worm wheel 603 is fixedly connected to the circumferential surface of the bidirectional screw 602. A worm 604 is rotatably connected to the first placement cavity 501, and one end of the worm 604 is fixedly connected to one end of the threaded rod 502. The worm 604 is meshed with the worm wheel 603. Two second nuts 605 are threadedly connected to the circumferential surface of the bidirectional screw 602. Two second slideways 606 are excavated on the fixed seat 1, and the two second slideways 606 are connected to the second placement cavity 601. Second sliders 607 are fixedly connected to the two second nuts 605, and the two second sliders 607 are respectively movable through the two second slideways 606 and are fixedly connected to the bottom ends of the two positioning plates 4.

[0041] In this embodiment, when the threaded rod 502 rotates to adjust the clamping plate 3 to clamp the mounting plate, the threaded rod 502 will drive the worm 604 to rotate, and the worm 604 causes the worm wheel 603 to drive the two-way screw 602 to rotate, and the two-way screw 602 drives the two second nuts 605 to move, so that the two second sliders 607 slide in the two second slideways 606 respectively, and the two second sliders 607 drive the two positioning plates 4 to move in a direction close to each other, so that the mounting plate moves to the middle part of the fixed seat 1, which can accurately correspond to the processing equipment and facilitate the processing of the processing equipment.

[0042] Specifically, the clamping mechanism includes a rotating opening 701, which is excavated on the fixed plate 2. An intermittent gear 702 is rotatably connected in the rotating opening 701. A rack 703 is slidably connected in the rotating opening 701, and the rack 703 is meshed with the intermittent gear 702. One end of the rack 703 is fixedly connected to a push plate 704, and the push plate 704 corresponds to the clamping plate 3. A rotating frame 705 is fixedly connected to the intermittent gear 702, and two first clamping blocks 706 are fixedly connected to the rotating frame 705. A fixed frame 707 is fixedly connected to the fixed plate 2, and a fixed rod 708 is fixedly connected in the fixed frame 707, and the rack 703 is slidably connected to the fixed rod 708. The outer surface of the fixed rod 708 is sleeved with a first spring 709, and the first spring 709 corresponds to the rack 703.

[0043] In this embodiment, when the clamping plate 3 moves to cooperate with the fixing plate 2 to clamp and fix the mounting plate, the clamping plate 3 pushes the mounting plate to move, and the mounting plate contacts the push plate 704, and the rack 703 is pushed by the push plate 704. The rack 703 slides on the fixing rod 708 and squeezes the first spring 709 through the fixing frame 707. At the same time, the rack 703 causes the intermittent gear 702 in the rotating mouth 701 to rotate, and the intermittent gear 702 drives the rotating frame 705 to rotate, and the rotating frame 705 drives the two first clamping blocks 706 to press down, and the two first clamping blocks 706 press and fix the mounting plate, so that the mounting plate is further fixed on the fixing seat 1. When the mounting plate is processed and taken out, the elastic force of the first spring 709 pushes the rack 703 to reset, which is convenient for the mounting plate to be fixed and used again.

[0044] Specifically, the auxiliary mechanism includes a rotating mouth 801, which is bored on the top clamping plate 3, a rotating plate 802 is rotatably connected in the rotating mouth 801, a second clamping block 803 is fixedly connected to the rotating plate 802, a spring groove 804 is bored on the top clamping plate 3, a T-shaped slide bar 805 movably passes through the spring groove 804, a second spring 806 is sleeved on the circumferential surface of the T-shaped slide bar 805, and the second spring 806 is located in the spring groove 804, one end of the T-shaped slide bar 805 is movably hinged with a sliding sleeve 807 through a hinge shaft, a push rod 808 is fixedly connected to the rotating plate 802, and the sliding sleeve 807 is slidably connected to the outer surface of the push rod 808.

[0045] In this embodiment, one end of the T-shaped slide bar 805 is in contact with the mounting plate. When the clamping plate 3 clamps the mounting plate, the mounting plate will cause the T-shaped slide bar 805 to slide in the spring groove 804 and compress the second spring 806. The T-shaped slide bar 805 pushes the sliding sleeve 807 to move, and the sliding sleeve 807 slides on the surface of the pushing rod 808, so that the pushing rod 808 drives the rotating plate 802 to rotate. The rotating plate 802 performs secondary clamping and fixing on the mounting plate through the second clamping block 803. When the mounting plate is processed and taken out, the elastic force of the second spring 806 resets the T-shaped slide bar 805, and the various components of the auxiliary mechanism are also reset, which is convenient for the mounting plate to be fixed and used again.

[0046] Specifically, the distance adjustment mechanism includes two adjustment rods 901 , which are respectively threadedly connected to the two positioning plates 4 , and the ends of the two adjustment rods 901 that are close to each other are rotatably connected to the distance adjustment plates 902 .

[0047] In this embodiment, the positions of the two distance adjustment plates 902 can be adjusted by rotating the two adjustment rods 901 , so that the two positioning plates 4 can position the installation plates of different sizes.

[0048] Specifically, a slide groove 10 is excavated on the fixed seat 1 , and the slide groove 10 is located in the rotating opening 701 , and a stabilizing slider 11 is fixedly connected to the bottom end of the rack 703 , and the stabilizing slider 11 is slidably connected in the slide groove 10 .

[0049] In this embodiment, the stabilizing slider 11 will slide in the slide groove 10 following the movement of the rack 703 , and the sliding connection between the slide groove 10 and the stabilizing slider 11 makes the movement of the rack 703 more stable.

[0050] Specifically, the ends of the two distance adjustment plates 902 that are away from each other are fixedly connected with scale rods 12 , and the two scale rods 12 movably penetrate the two positioning plates 4 .

[0051] In this embodiment, the two scale rods 12 facilitate the determination of the moving distance of the two distance adjusting plates 902 , and at the same time can ensure the stability of the two distance adjusting plates 902 when moving.

[0052] Specifically, a waste outlet 13 is formed at the bottom of the fixing seat 1 , and the waste outlet 13 is connected to the first placement cavity 501 and the second placement cavity 601 .

[0053] In this embodiment, a certain amount of waste chips are easily generated during the processing of the mounting plate. The waste chips can easily enter the fixing seat 1 through the two second slideways 606 and the first slideway 504 and are inconvenient to clean. The waste discharge port 13 makes it easy to clean the fixing seat 1.

[0054] Working principle: When the mounting plate needs to be fixed during processing, the mounting plate is placed on the fixing seat 1, and the first nut 503 is moved in the first placing cavity 501 by rotating the threaded rod 502 in the first placing cavity 501, and the first nut 503 drives the first slider 505 to slide in the first slideway 504, so that the top plate 3 moves, and the top plate 3 cooperates with the fixing plate 2 to clamp and fix the mounting plate. At the same time, the threaded rod 502 drives the worm 604 to rotate, and the worm 604 causes the worm wheel 603 to drive the bidirectional screw 602 to rotate, and the bidirectional screw 602 drives the two second nuts 605 to move, so that the two second sliders 607 slide in the two second slideways 606 respectively, and the two second sliders 607 drive the two positioning plates 4 to move in the direction of approaching each other, so that the mounting plate moves to the middle part on the fixing seat 1, which can accurately correspond to the processing equipment, and the top plate 3 cooperates with the fixing plate 2 to clamp the mounting plate. 3 pushes the mounting plate to move, the mounting plate contacts the push plate 704, and the push plate 704 pushes the rack 703, the rack 703 slides on the fixing rod 708 and squeezes the first spring 709 through the fixing frame 707, and at the same time, the rack 703 rotates the intermittent gear 702 in the rotating opening 701, and the intermittent gear 702 drives the rotating frame 705 to rotate, and the rotating frame 705 drives the two first pressing blocks 706 to press down, and the two first pressing blocks 706 press and fix the mounting plate, so that the mounting plate is pressed and fixed on the fixing seat 1. At the same time, the mounting plate makes the T-shaped slide bar 805 slide in the spring groove 804 and compress the second spring 806, and the T-shaped slide bar 805 pushes the sliding sleeve 807 to move, and the sliding sleeve 807 slides on the surface of the pushing rod 808, so that the pushing rod 808 drives the rotating plate 802 to rotate, and the rotating plate 802 performs secondary pressing and fixing on the mounting plate through the second pressing block 803, so that the mounting plate further maintains stability.
