DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a hardware polishing positioning device comprises: an operating table 1, the top of the operating table 1 is slidably connected to two mounting frames 2, the inner wall of the mounting frame 2 is slidably connected to a slider 3, a grinder 4 is installed at the bottom end of the slider 3, and a positioning mechanism 5 is arranged at the top of the operating table 1; wherein the positioning mechanism 5 comprises a mounting plate 51 fixedly connected to the middle of the top of the operating table 1, a placing plate 52 is fixedly connected to the middle of the top of the mounting plate 51, and two moving plates 52 are slidably connected to the inner wall of the mounting plate 51. A movable frame 53, a spring 54 is fixedly connected between one side of the movable frame 53 and the inner wall of the mounting plate 51, the inner wall of the movable frame 53 is slidably connected to a limit plate 55, and the top of the limit plate 55 passes through the movable frame 53, the top of the operating table 1 is fixedly connected to a mounting frame 59, the top of the mounting frame 59 is rotatably connected to a first electric push rod 510, the bottom end of the first electric push rod 510 passes through the mounting frame 59 and is fixedly connected to a fixed plate 511, and the bottom end of the fixed plate 511 is fixedly connected to a magnetic block 512.

[0026] The inner wall of the operating table 1 is rotatably connected with a bidirectional screw rod, and the surface of the bidirectional screw rod is threadedly connected with a moving block. The threads of the two moving blocks connected to the bidirectional screw rod are opposite, and the top of the moving block is fixedly connected to the bottom of the corresponding installation frame 2. When grinding the hardware, the staff can rotate the bidirectional screw rod to make the two installation frames 2 drive the corresponding grinder 4 to move and approach each other. The grinder 4 includes a motor and a grinding disc. When the grinding disc of the grinder 4 contacts the surface of the hardware, the controller can start the motor to drive the grinding disc to run and grind the hardware. The inner bottom walls of the two installation frames 2 are fixedly connected with a second electric push rod, and the other end of the second electric push rod is fixedly connected to the bottom end of the slider 3. The slider 3 can be driven up and down by starting the second electric push rod, so that the grinder 4 can be driven to move up and down during grinding to grind the hardware.

[0027] like Figure 3 and Figure 5 As shown, the positioning mechanism 5 also includes a bolt 56 threadedly connected to one side of the inner wall of the mounting plate 51, the bottom end of the bolt 56 penetrates the mounting plate 51 and is rotatably connected to a moving plate 57, the top end of the moving plate 57 is slidably connected to two connecting rods 58, and the other ends of the two connecting rods 58 are respectively fixedly connected to one side of the corresponding limiting plate 55. The top end of the placement plate 52 is rotatably connected to round balls 518 distributed in a rectangular array.

[0028] When the device is in the initial state, the horizontal height of the top of the two limit plates 55 is higher than the horizontal height of the top of the placement plate 52, and the two moving frames 53 are close to each other under the action of the corresponding springs 54. When the rectangular hardware is positioned, the hardware is placed between the two limit plates 55, and the bottom of the hardware contacts the surface of the round ball 518 at the top of the placement plate 52. At this time, under the action of the spring 54, the moving frame 53 will drive the two limit plates 55 to initially limit the hardware, and keep the hardware and the placement plate 52 in a centered state. At this time, the controller starts the first electric push rod 510 to push the fixed plate 51 1 and the magnetic block 512 move downward synchronously, so that the fixing plate 511 and the magnetic block 512 are pressed against the hardware from the top, and the hardware is fixed under the action of the placement plate 52. After completing this operation, the staff rotates the bolt 56 to push the movable plate 57 to move downward, and drives the limit plate 55 to move downward under the action of the connecting rod 58, so that the limit plate 55 shrinks into the movable frame 53. When the movable plate 57 cannot move downward further, the top of the connecting rod 58, the top of the limit plate 55 and the top of the placement plate 52 are at the same horizontal height, so that the side of the hardware is not blocked during grinding.

[0029] like Figure 2 and Figure 4As shown, a ring 513 is fixedly connected to the surface of the first electric push rod 510, and a limit rod 514 is slidably connected to the inner wall of the ring 513. Two limit holes 515 are opened at the top of the mounting frame 59. The upper end of the inner wall of the limit hole 515 is curved in an arc shape, and the angle between the centers of the two limit holes 515 is ninety degrees. The bottom end of the limit rod 514 is curved in a spherical shape, and the diameter of the limit rod 514 is the same as the diameter of the inner wall of the limit hole 515.

[0030] When the device is in the initial state, the limit rod 514 is engaged with one of the limit holes 515. When it is necessary to grind the other two sides of the rectangular hardware, first move the two grinders 4 away from the hardware, then pull the limit rod 514 upward to release the engagement with the limit hole 515, and rotate the ring 513 clockwise to drive the first electric push rod 510 to rotate synchronously, and drive the hardware to rotate synchronously by ninety degrees under the action of the fixed plate 511 and the magnetic block 512. When the hardware rotates, its bottom will drive the ball 518 to rotate synchronously, and insert the limit rod 514 into the other limit hole 515. At this time, the other two sides of the hardware are in the same horizontal plane as the grinder 4.

[0031] like Figure 4 As shown, the surface of the ring 513 is fixedly connected to a limit block 517, and the top of the mounting frame 59 is fixedly connected to a fixing block 516. When the ring 513 is rotated clockwise, when one side of the limit block 517 is in contact with one side of the fixing block 516, the ring 513 drives the first electric push rod 510 and the fixing plate 511 to rotate ninety degrees.

[0032] When the utility model is in use, when the rectangular hardware is positioned, the hardware is placed between the two limit plates 55, and the bottom end of the hardware contacts the surface of the round ball 518 at the top of the placement plate 52. At this time, under the action of the spring 54, the moving frame 53 drives the two limit plates 55 to perform preliminary limit on the hardware, and keeps the hardware and the placement plate 52 in a centered state. At this time, the first electric push rod 510 is started by the controller to push the fixed plate 511 and the magnetic block 512 to move downward synchronously, so that the fixed plate 511 and the magnetic block 512 are pressed against the hardware from the top, and the hardware is fixed under the action of the placement plate 52. After the fixation is completed, the staff rotates the bolt 56 to push the moving plate 57 downward, and drives the limit plate 55 to move downward under the action of the connecting rod 58. When the moving plate 57 cannot continue to move downward, the top of the connecting rod 58, the top of the limit plate 55 and the top of the placement plate 52 are at the same horizontal height. At this time, the grinder 4 is driven to grind the surface of the hardware.

[0033] When grinding the other two sides of the rectangular hardware, first move the two grinders 4 away from the hardware, then pull the limit rod 514 upward to release the engagement with the limit hole 515, and rotate the ring 513 and the first electric push rod 510 clockwise by ninety degrees, and drive the hardware to rotate synchronously by ninety degrees under the action of the fixed plate 511 and the magnetic block 512, and insert the limit rod 514 into the other limit hole 515. At this time, the other two sides of the hardware are in the same horizontal plane as the grinder 4, and the other two sides of the hardware can be ground.

[0034] It should be noted that the grinder 4, the first electric push rod 510, the second electric push rod, etc. in the above description are all relatively mature devices in the existing technology. The specific models can be selected according to actual needs. At the same time, the grinder 4, the first electric push rod 510, and the second electric push rod can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
