Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a precision metal hardware fixture. Background Technology

[0002] A jig is a tool used in industrial production to fix, support, or position workpieces, and is widely used in industries such as machining, electronics manufacturing, and automobile assembly. In the field of hardware processing, jigs play a particularly important role, ensuring the accuracy and stability of workpieces during processing, thereby improving production efficiency and product quality.

[0003] Fixtures are typically custom-made for specific workpieces and are used for rapid positioning of those workpieces. However, in actual use, the fit between the fixture and the components requires a certain clearance to prevent interference. This clearance will cause the tolerances to accumulate and increase. At the same time, the fixture, as a third party, will inevitably increase the length of the dimensional chain, which will also increase the tolerances. This reduces the positioning accuracy of the fixture. In addition, the materials used for the fixture itself have low wear resistance, and wear during assembly will reduce the accuracy of the fixture. Wear will increase with the increase of usage time, leading to a gradual decrease in accuracy. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0028] A precision metal hardware fixture, comprising:

[0029] The workbench 1 includes a table surface 12. A positioning device is provided on the rear side of the top surface of the table surface 12. The positioning device uses image recognition technology to position the workpiece. A limiting groove 13 is provided longitudinally on the top surface of the table surface 12. A pre-fixing component 2 is provided in the middle of the top surface of the table surface 12. A clamping component 3 is provided on the outside of the pre-fixing component 2. The pre-fixing component 2 uses negative pressure to fix the workpiece. The clamping component 3 is used to clamp the workpiece from the side.

[0030] A support 11 is welded to the bottom surface of the tabletop 12, and the support 11 is used to support the tabletop 12.

[0031] The limiting groove 13 adopts a T-shaped groove, and the limiting groove 13 extends longitudinally through the table surface 12.

[0032] The positioning device includes an adjustment bracket 14, which is connected to a camera 15 and a display device 16. The positions of the camera 15 and the display device 16 are adjustable, and the display device 16 is used to display the image captured by the camera 15.

[0033] The adjustment bracket 14 can be a known camera bracket, which can adjust the position of the camera 15 in the horizontal, vertical and vertical directions. The lens of the camera 15 is vertically downward and is used to capture the position of the workpiece on the table 12.

[0034] The captured images can be compared with preset standard positions, and the comparison results are displayed on the display device 16, making it convenient for operators to adjust the workpiece position based on the comparison.

[0035] The pre-fixed component 2 includes a first base 21, which is engaged with the limiting groove 13 and can slide along the limiting groove 13. An adsorption plate 22 is fixedly installed on the top surface of the first base 21 by bolts.

[0036] The bottom of the first base 21 is provided with a fixing member 4, which includes a locking block 41. The locking block 41 is adapted to the limiting groove 13. The locking block 41 is fixedly connected to the first base 21 by a locking bolt 42. By rotating the locking bolt 42, the friction between the locking block 41 and the limiting groove 13 can be adjusted.

[0037] When the locking bolt 42 is loosened, the locking block 41 can move along the limiting groove 13, which facilitates the movement of the first base 21.

[0038] When the locking bolt 42 is tightened, the locking block 41 cannot be moved, thus fixing the first base 21.

[0039] An air passage 23 is provided on the top surface and one side of the adsorption plate 22, and the air passage 23 is connected to a negative pressure component 24 through a pipe.

[0040] The negative pressure component 24 can be a known vacuum pump. The vacuum pump can be connected to a pressure stabilizing tank via a pipe. The pressure stabilizing tank can be connected to the outlet of the air passage 23 on the side of the adsorption plate 22 via a pipe, so that the pressure at the air inlet of each air passage 23 is uniform. A solenoid valve can be installed between the pressure stabilizing tank and the air passage 23 to control the connection between the air passage 23 and the pressure stabilizing tank.

[0041] The negative pressure component 24 can generate negative pressure at the air inlet of the air passage 23 on the top surface of the adsorption plate 22, thereby adsorbing the workpiece.

[0042] The clamping assembly 3 includes several second bases 31, which are engaged with the limiting groove 13 and can slide along the limiting groove 13. A power source 34 is rotatably mounted on the top surface of each second base 31 through a connecting sleeve 32.

[0043] The bottom surface of the second base 31 is fixedly installed with a locking block 41 by a locking bolt 42. The locking block 41 engages with the limiting groove 13 and can move along the limiting groove 13. The friction between the locking block 41 and the limiting groove 13 can be adjusted by adjusting the number of rotations of the locking bolt 42.

[0044] The power source 34 can be a slide cylinder or a servo actuator. In this embodiment, a slide cylinder is used, and the power source 34 can be driven by a stable air source, such as an air compressor.

[0045] A pad 33 is fixedly installed on the bottom surface of the power source 34 by screws. The pad 33 is used to adjust the height of the power source 34. A locking handle 36 is provided on the top surface of the power source 34. The locking handle 36 is threadedly connected to the connecting sleeve 32.

[0046] Tightening the locking handle 36 applies pressure to the power source 34, causing the pad 33 to press against the second base 31, thus securing the power source 34. Loosening the locking handle 36 allows the power source 34 to rotate easily, thereby facilitating the adjustment of its angle.

[0047] The power source 34 is connected to the clamping block 35, which can drive the clamping block 35 to move towards the workpiece. The shape of the clamping block 35 is customized according to the workpiece.

[0048] The clamping block 35 can clamp the workpiece. Because the shape of the clamping block 35 is customized to fit the workpiece, the positioning accuracy can be improved. At the same time, when maintaining and replacing, only the clamping block 35 with more severe wear needs to be replaced, which can reduce maintenance costs.

[0049] In this embodiment, when the operator uses this equipment, first selects a suitable clamping point according to the shape of the workpiece, and then processes a suitable clamping block 35 according to the clamping point.

[0050] Based on the shape of the workpiece and the pre-selected clamping point, select the appropriate number of pre-fixed components 2 and clamping components 3, adjust the position of the first base 21 and the second base 31, then fix the clamping block 35 to the power source 34 with screws, and then adjust the angle of the power source 34.

[0051] Place the workpiece on the top surface of the adsorption plate 22, control the negative pressure component 24 to work, adsorb the workpiece, then control the power source 34 to work, use the clamping block 35 to clamp the workpiece, adjust according to the clamping situation, after adjustment, control the braking power source 34 to work, release the clamping block 35 from the workpiece, and then use the camera 15 to take a picture of the position of the workpiece and record it as the initial position.

[0052] During processing, the workpiece is placed on the top surface of the adsorption plate 22, and the position of the workpiece on the table 12 is captured by the camera 15. The captured image is compared with the preset standard position, and the comparison result is displayed on the display device 16. The operator adjusts the position of the workpiece according to the comparison.

[0053] Once the position is suitable, the negative pressure component 24 is activated to adsorb the workpiece, and then the power source 34 is activated to clamp the workpiece using the clamping block 35. After secure clamping, subsequent processing operations can be performed.

[0054] After processing is completed, first release the clamping block 35 from the workpiece, then stop the operation of the negative pressure component 24, and release the adsorption plate 22 from fixing the workpiece.
