Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, and particularly to a fixing device for hardware processing. Background Art

[0002] Hardware refers to tools made by processing and casting metals such as gold, silver, copper, iron, and tin. They are used to fix things, process things, and decorate. During their production and processing, they need to be clamped and fixed to ensure the stability of the hardware during processing. Therefore, a hardware processing fixing device is often used in the process of hardware processing.

[0003] A hardware processing fixing device disclosed in Chinese patent CN219542884U solves the problem that the existing hardware fixing device is inconvenient to adjust and fix hardware of different sizes, and ensures the rationality of the device. However, while solving the problem, the hardware processing fixing device has the following defects:

[0004] The setting of the connecting slide rod makes a certain distance between the placement shell and the top of the fixed platform. This setting requires the operator to lift the hardware when the two placement shells are put on the outside of the hardware. At the same time, after the placement shell completes the fixation of the hardware, the placement shell will block a part of the top of the hardware. This phenomenon easily makes the blocked part of the top of the hardware difficult to process. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical defects described in the background technology.

[0006] To this end, one purpose of the utility model is to propose a fixing device for hardware processing, aiming to solve the problem that the fixing device for hardware processing in the prior art needs to lift the hardware when fixing the hardware, and the placement frame will block part of the top of the hardware.

[0008] Preferably, any of the above schemes is that a fixed block is fixedly connected to the bottom of the workbench, and a first bidirectional screw is rotatably connected to one side of the fixed block, and the first bidirectional screw is threadedly connected to the drive plate. The two movable columns can be brought close to each other by rotating the bidirectional screw, and at the same time, the two movable columns can clamp and fix the two sides of the hardware through the placement grooves. Since the first bidirectional screw is arranged at the bottom of the workbench, debris generated when processing the hardware will not fall onto the first bidirectional screw.

[0009] Preferably, one side of the driving plate is rotatably connected to a second bidirectional screw, and the second bidirectional screw is threadedly connected to the driving column. By rotating the second bidirectional screw, the two extrusion plates can clamp and fix the other two sides of the hardware, and the second bidirectional screw can prevent debris from falling onto the second bidirectional screw under the cover of the moving column.

[0010] Preferably, any of the above schemes is provided with a collecting trough on the top of the workbench, the bottom of the collecting trough is fixedly connected to a support frame, and the support frame is movably connected to a collecting box inside, so that the debris generated when processing the hardware can fall directly into the inside of the collecting box through the collecting trough, so that the collecting box can collect the debris in a centralized manner.

[0011] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0012] 1. By setting up the movable column, placement groove, roller and extrusion plate, it is not necessary to manually lift the hardware when fixing it, and the fixed hardware is in the center of the workbench, so the whole operation is relatively convenient. The placement groove and extrusion plate only fix the side of the hardware, so that the top of the hardware will not be affected when processing.

The movement of the two pressing plates 7 can make the other two sides of the hardware contact each other. A roller 8 is rotatably connected to the inner wall of the placing groove 4, and the inner wall of the placing groove 4 is in contact with the side of the hardware through the roller 8. This setting enables that when one of the pressing plates 7 first contacts the hardware, the pressing plate 7 can push the hardware and make the other pressing plate 7 also contact the hardware.

[0023] Embodiment 1: A fixing block 9 is fixedly connected to the bottom of the workbench 1. One side of the fixing block 9 is rotatably connected with a first bidirectional screw 10.

By driving the motor 12, the motor 12 can drive the first bidirectional screw 10 to rotate.

[0025] Embodiment 3: A second bidirectional screw 13 is rotatably connected to one side of the driving plate 2. The second bidirectional screw 13 is threadedly connected to the driving column 6. The second bidirectional screw 13 is connected to the driving plate 2 through a bearing. When the two extrusion plates 7 are moved, the second bidirectional screw 13 is directly rotated, so that the second bidirectional screw 13 drives the two extrusion plates 7 to move inside the placement groove 4.

[0026] Embodiment 4: A collecting trough 14 is provided on the top of the workbench 1, and the inner wall of the collecting trough 14 is inclined so that the debris falling into the collecting trough 14 can quickly slide down.

[0028] Embodiment 6: The bottom of the workbench 1 is fixedly connected with a support leg 19, and the bottom of the support leg 19 is fixedly connected with a shock-absorbing pad 20. The support leg 19 can support the workbench 1, and with the assistance of the shock-absorbing pad 20, the entire device is not prone to shaking due to vibration when processing hardware.

[0029] The working principle of the utility model is as follows: when in use, the motor 12 is started, so that the motor 12 drives the two moving columns 3 to move on the workbench 1 and move to a suitable position through the first bidirectional screw 10, and then the hardware is directly placed inside the placement groove 4, and the two moving columns 3 are driven by the motor 12 and the first bidirectional screw 10, and the placement groove 4 is contacted with the side of the hardware through the roller 8, and then the second bidirectional screw 13 is rotated through the control ring 17, so that the second bidirectional screw 13 drives the two extrusion plates 7 to move, and when one of the extrusion plates 7 is first in contact with the hardware, the hardware can be moved inside the placement groove 4 with the assistance of the roller 8 and the push of the extrusion plate 7, and when the two extrusion plates 7 are in contact with the hardware, the rotation of the control ring 17 is stopped, and then the fixed hardware is started for processing, and most of the debris generated during processing will fall directly into the collection box 16 through the collection groove 14.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Start the motor 12, so that the motor 12 drives the first bidirectional screw 10 to rotate, and the first bidirectional screw 10 drives the two moving columns 3 to move to a suitable position, and then directly place the hardware inside the placement slot 4. At this time, continue to start the motor 12, so that the two moving columns 3 clamp and fix the two sides of the hardware with the assistance of the motor 12 and the first bidirectional screw 10, and then rotate the second bidirectional screw 13, so that the second bidirectional screw 13 drives the two extrusion plates 7 to move. When the extrusion plates 7 move When one extrusion plate 7 contacts with the hardware first, since the moving column 2 contacts with the side of the hardware through the roller 8, the extrusion plate 7 can push the hardware and make the other extrusion plate 7 contact with the hardware. At this point, the object is fixed on the workbench, and the fixed hardware is in the center of the workbench 1. The whole operation process is relatively convenient. Since the placement groove 4 on the moving column 3 cooperates with the extrusion plate 7 to only fix the four sides of the hardware, there will be no obstruction when processing the top of the hardware.

[0032] 2. The first bidirectional screw 10 drives the movable column 3 through the driving plate 2, and the first bidirectional screw 10 is arranged at the bottom of the workbench 1, and the second bidirectional screw 13 drives the extrusion plate 7 through the driving column 6, and the second bidirectional screw 13 is arranged at the bottom of the movable column 3. The above arrangement prevents the debris generated during the processing of the hardware from falling directly onto the two bidirectional screws, so that the two bidirectional screws can work normally, and most of the generated debris will fall directly into the collection box 16 through the collection trough 14, so that the overall practicality of the device is higher.
