Technical Field

[0001] The invention belongs to the field of grinding technology, and in particular relates to a grinding device for producing alarm shells, which is intended to efficiently grind the alarm shells. Background Art

[0002] The grinding device for alarm housing production is a special equipment used to perform fine processing on the surface of the alarm housing. Its main function is to remove burrs, burrs, scratches and other defects after the housing is formed, and to improve the surface smoothness and aesthetics.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1-9 The embodiment of the present invention provides a grinding device for producing an alarm housing, comprising a base 1 and a fixing plate 2 fixedly connected to the side of the base 1. A mechanical grinding piece 3 is provided on the side of the fixing plate 2 close to the base 1. A fixing piece is provided on the top of the base 1 for fixing the alarm housing. A rotating member is provided inside the base 1, and the rotating member is used to rotate the fixed member; A grinding member is provided on the top of the base 1, and the grinding member is used to grind the gap of the alarm housing.

[0023] In the above technical solution, the alarm housing is fixed from the inside by a fixing part, so that the grinding part can enter the gap of the alarm housing for grinding, avoiding the presence of burrs in the gap of the alarm housing, and thus avoiding the trouble of manual burr removal later, improving the efficiency and quality of grinding the alarm housing, and avoiding abnormal alarm function. The rotating part rotates the fixing part, thereby driving the alarm housing to rotate, so that the gap on each side of the alarm housing can be ground, avoiding the need to remove and reinstall the alarm housing when grinding, improving the efficiency of grinding the alarm housing, and reducing manual operation time.

[0024] Specifically, the rotating part includes a limit rotating block 401, which is rotatably connected to the inside of the base 1, and one end of the limit rotating block 401 is fixedly connected to a spiral blade column 402, and the end of the spiral blade column 402 away from the limit rotating block 401 is fixedly connected to a rotating wheel 403, and the side of the rotating wheel 403 away from the spiral blade column 402 is slidably connected to a rotating hand column 404.

[0025] In the above technical solution, the limiting rotating block 401 is used to limit the rotating hand column 404 so that the spiral blade column 402 can be driven to rotate when the rotating hand column 404 moves.

[0026] Specifically, the rotating part also includes a rotating bottom block 405, which is rotatably connected to the inside of the base 1.

The top of the rotating gear 406 is fixedly connected to a fixed shell 407, and the inside of the fixed shell 407 is rotatably connected to a rotating connecting plate 408. The top of the fixed shell 407 is provided with a plurality of sliding fixed grooves 41.

[0027] In the above technical solution, by means of the engaging relationship between the rotating gear 406 and the spiral blade column 402 , the circular motion of the rotating hand column 404 can drive the fixing part to rotate, thereby driving the alarm housing to rotate.

[0028] Specifically, the fixing part includes a connecting column 501, which is fixedly connected to the side of the rotating connecting plate 408. The middle part of the connecting column 501 is rotatably connected to a rotating clamping plate 502. The two sides of the rotating clamping plate 502 are fixedly connected to a return spring 503. The other end of the return spring 503 is fixedly connected to the inner side of the rotating connecting plate 408. A plurality of snap-in grooves 51 are provided on the side of the fixed shell 407. The side of the rotating clamping plate 502 away from the connecting column 501 is arranged inside the snap-in groove 51.

[0029] In the above technical solution, the rotating clamping plate 502 can be automatically engaged with the engaging groove 51 through the elastic torsional action of the reset spring 503, thereby preventing the rotating clamping plate 502 from automatically performing circular motion.

[0030] Specifically, the fixing part also includes a plurality of opening and closing rotating blocks 504, which are rotatably connected to the top of the rotating connecting plate 408, and the top of the opening and closing rotating block 504 is fixedly connected to the fixed connecting plate 505, and the top of the fixed connecting plate 505 is fixedly connected to the fixed sliding column 506, and the fixed sliding column 506 is slidably arranged inside the sliding fixed groove 41.

[0031] In the above technical solution, the fixed connecting plate 505 is driven to rotate so that the fixed sliding column 506 is driven to slide by the rotating connecting plate 408, thereby fixing the alarm housing.

[0032] Specifically, the hole grinding part includes two sliding bottom blocks 601, which are slidably connected to the top of the base 1. The top of the sliding bottom block 601 is fixedly connected to a sliding fixed column 602. The top of the sliding fixed column 602 is slidably provided with a sliding support block 603. The top of the sliding support block 603 is fixedly connected to a lifting gear column 604, and a gear is provided on one side of the lifting gear column 604.

[0033] In the above technical solution, the grinding member is driven to move by the movement of the sliding bottom block 601 and the sliding support block 603 .

[0034] Specifically, the hole grinding component includes a lifting shell 605, which is slidably connected to the middle part of the lifting gear column 604. A lifting gear 606 is provided on one side of the lifting gear column 604. The lifting gear 606 is engaged with the lifting gear column 604. The middle part of the lifting gear 606 is rotatably connected to a rotating column 607. The rotating column 607 is connected to the middle part of the lifting shell 605. The end of the rotating column 607 close to the fixed plate 2 is fixedly connected to a hole grinding needle 608, and the end of the rotating column 607 away from the fixed plate 2 is fixedly connected to a rotating motor 609.

[0035] In the above technical solution, the lifting clamping column 604 is engaged with the lifting gear 606 to drive the rotating clamping column 607 to move up and down, thereby driving the grinding needle 608 to move up and down.

[0036] Specifically, a bevel gear 610 is provided on the side of the lifting gear 606 away from the lifting gear column 604, and the bevel gear 610 is engaged with the lifting gear 606. The side of the bevel gear 610 away from the lifting gear 606 is fixedly connected to a rotary wheel connecting plate 611, and the rotary wheel connecting plate 611 is rotatably connected to the side of the lifting shell 605. The side of the rotary wheel connecting plate 611 away from the bevel gear 610 is slidably connected to a lifting hand column 612.

[0037] In the technical scheme, the oblique gear 610 is engaged with the lifting gear 606, the circular motion of the lifting handle 612 drives the motion of the lifting gear 606, and then drives the lifting motion of the rotating clamping column 607.

[0038] Specifically, a plurality of rotating clamping grooves 42 are arranged on the side surface of the base 1 in a ring shape, one end of the rotating handle 404 close to the base 1 is clamped with the rotating clamping groove 42, and the side surface of the rotating handle 404 is fixedly connected with a rotating limiting plate 409 which is slidingly arranged in the inside of the rotating wheel disc 403.

[0039] In the technical scheme, the rotating handle 404 is clamped with the rotating clamping groove 42, the rotating gear 406 is fixed, and then the alarm shell is fixed, so that the polishing device cannot damage the alarm shell.

[0040] Specifically, a plurality of lifting clamping grooves 61 are arranged on one side of the lifting shell 605 close to the lifting handle 612 in a ring shape, one end of the lifting handle 612 close to the lifting shell 605 is clamped with the lifting clamping groove 61, and the side surface of the lifting handle 612 is fixedly connected with a lifting limiting plate 613 which is slidingly arranged in the inside of the rotating connecting plate 611.

[0041] In the technical scheme, the lifting handle 612 is clamped with the lifting clamping groove 61, the rotating oblique gear 610 is fixed, and then the lifting gear 606 is fixed, so that the lifting shell 605 cannot move downward due to the weight.

[0042] Specifically, the working principle and operation method of the present application are as follows: When in use, the operator places the alarm shell on the fixed slide column 506, moves the rotating clamping plate 502 upward, the rotating clamping plate 502 moves upward around the connecting rotating column 501, and then is no longer clamped with the clamping groove 51, and the reset spring 503 is twisted, at this time, the rotating clamping plate 502 is moved, the rotating clamping plate 502 drives the rotating connecting plate 408 to rotate through the connecting rotating column 501, the rotating connecting plate 408 drives the opening and closing rotating block 504 to move in a circle around the rotating bottom block 405, the opening and closing rotating block 504 drives one end of the fixed connecting plate 505 close to the opening and closing rotating block 504 to move in a circle around the rotating bottom block 405, and then drives the fixed slide column 506 to move, since the fixed slide column 506 is limited to slide only by the sliding fixed groove 41, the fixed slide column 506 slides away from the rotating bottom block 405, and then abuts against the inside of the alarm shell.

[0043] At this time, the rotating clamping plate 502 is released. Under the elastic torsion action of the reset spring 503, the rotating clamping plate 502 rotates downward and then engages with the engaging groove 51, so that the rotating clamping plate 502 is fixed. Then, the rotating connecting plate 408 is fixed through the rotating clamping plate 502. The rotating connecting plate 408 fixes the fixed sliding column 506 through the fixed connecting plate 505, thereby fixing the alarm housing.

[0044] At this time, the operator starts the device and uses the mechanical grinding piece 3 to grind the outside of the alarm housing, and then starts the rotating motor 609. The rotating motor 609 drives the rotating clamping column 607 to rotate, and then drives the hole grinding needle 608 to rotate, and at the same time moves the sliding bottom block 601, so that the sliding bottom block 601 moves in the direction close to the fixed shell 407, and then drives the spiral leaf column 402 to move in the direction close to the fixed shell 407. The spiral leaf column 402 drives the lifting clamping column 604 to move in the direction close to the fixed shell 407 through the sliding support block 603, and then drives the lifting shell 605 to move in the direction close to the fixed shell 407. The lifting shell 605 drives the hole grinding needle 608 to move in the direction close to the fixed shell 407 through the rotating clamping column 607, and at the same time moves the sliding support block 603, so that the hole grinding needle 608 moves in the direction close to and away from the fixed plate 2, so that the hole grinding needle 608 enters the gap of the alarm housing and grinds the gap of the alarm housing.

[0045] At this time, the lifting hand column 612 is slid away from the lifting shell 605, driving the lifting limit plate 613 to slide inside the rotary connecting plate 611, so that the lifting hand column 612 is no longer engaged with the lifting slot 61, and then the lifting hand column 612 is rotated to make the lifting hand column 612 drive the rotary connecting plate 611 to rotate, and the rotary connecting plate 611 drives the bevel gear 610 to rotate. Since the bevel gear 610 is engaged with the lifting gear 606, the rotation of the bevel gear 610 will drive the lifting gear 606 to rotate. Since the lifting gear 606 is engaged with the lifting card tooth column 604, as the lifting gear 606 rotates, the lifting gear 606 moves up or down, and then drives the grinding needle 608 to move up or down by rotating the card column 607, so that the grinding needle 608 completely grinds the gap of the alarm housing.

[0046] As the gap on one side is polished, the sliding bottom block 601 is moved away from the fixed shell 407, so that the grinding needle 608 leaves the gap of the alarm shell, and at the same time, the lifting hand column 612 is slid toward the lifting shell 605, so that the lifting hand column 612 is re-engaged with the lifting slot 61, so that the rotating bevel gear 610 is fixed, thereby ensuring that the lifting gear 606 is fixed, thereby preventing the lifting shell 605 from moving downward due to weight.

[0047] The rotation of the hand column 404 is carried out in a direction close to the base 1, so that the rotating hand column 404 is re-engaged with the rotating slot 42, so that the rotating gear 406 is fixed, and the alarm housing is fixed, and the grinding work is continued.

[0048] When the gap of the alarm housing is completely polished, the rotating clamping column 607 is closed and the sliding bottom block 601 is moved, so that the sliding bottom block 601 drives the grinding hole needle 608 to move in the direction away from the fixed housing 407. At this time, the rotating clamping plate 502 is rotated upward, and the rotating clamping plate 502 is no longer engaged with the clamping groove 51, and the reset spring 503 is twisted. At the same time, the rotating clamping plate 502 is rotated, and the rotating clamping plate 502 drives the rotating connecting plate 408 to rotate through the connecting rotating column 501. The rotating connecting plate 408 drives the opening and closing rotating block 504 to perform a circular motion around the rotating bottom block 405. The opening and closing rotating block 504 drives the fixed connecting plate 505 close to the end of the opening and closing rotating block 504 to perform a circular motion around the rotating bottom block 405, thereby driving the fixed sliding column 506 to slide in the direction close to the rotating bottom block 405, thereby leaving the inner side of the alarm housing, making it convenient for the alarm housing to be removed.

[0049] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
