[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] See also Figure 1-Figure 13 , a semi-automatic assembly device for manufacturing a drill chuck assembly provided in one embodiment of the present application, includes a workbench 1, on the edge of which are sequentially provided with a nut sleeve feeding mechanism 4, a spring feeding mechanism 5, a nut feeding mechanism 6, a loading mechanism 7, a feeding conveying mechanism 8 and a pressing mechanism 9 distributed in a circular array.

The number of workpiece carriers 2 is not required here and can be set according to actual conditions. Specifically, the bracket 15 fixedly supports the driving mechanism 3, and the driving mechanism 3 drives the turntable 16 to rotate. When the turntable 16 rotates, it drives a plurality of workpiece carriers 2 on the upper surface of the turntable 16 to rotate together, and the workpiece carriers 2 rotate to transport the workpieces transported by each mechanism.

[0022] The upper surface of the workpiece carrier 2 is laterally provided with a U-shaped groove 201, the U-shaped groove 201 includes a channel 2012 and a limiting groove 2011, the channel 2012 is connected with the limiting groove 2011 and faces the outer edge of the workbench 1. The limiting groove 2011 is located at the center of the workpiece carrier 2, and the bottom surface of the channel 2012 is higher than the bottom surface of the limiting groove 2011. With such a design, the workpieces transported by each mechanism can be fixed in the limiting groove 2011 to prevent the workpieces from falling off, thereby improving the safety of production, reducing the damage of the workpieces, and improving the production efficiency.

[0023] A fixing seat 202 is fixedly installed at the bottom of the workpiece carrier 2. The fixing seat 202 surrounds the bottom of the workpiece carrier 2. The fixing seat 202 is convex on all sides and concave in the middle. The upper surface is provided with a concave for installing screws to fix the workpiece carrier 2 on the turntable 16.

[0024] In summary, the present application cleverly utilizes the limiting groove 2011 of the U-shaped groove 201 in the workpiece carrier 2 to fix the workpieces transported by each mechanism, so that the workpieces can be firmly fixed on the workpiece carrier 2 during transportation, effectively avoiding the workpiece from falling off and ensuring the quality of the workpiece; the workpiece carrier 2 is fixed on the upper surface of the turntable 16 using the fixing seat 202, thereby ensuring the stability of the workpiece carrier 2 in transportation, and further ensuring the quality of the workpiece and the efficiency of transportation.

[0025] The nut sleeve feeding mechanism 4, the nut feeding mechanism 6 and the spring sheet feeding mechanism 5 all include a bracket 15, a vibration feeding mechanism 401 and a conveyor belt 402. The vibration feeding mechanism 401 is installed on the bracket 15, and the vibration feeding mechanism 401 includes a conveying pipe 4011 and a vibration plate 4012. The edge of the vibration plate 4012 is provided with a conveying pipe 4011, wherein the conveying pipe 4011 is communicated with the vibration plate 4012, and the pipe mouth of the conveying pipe 4011 is connected to the conveyor belt 402.

[0026] When the nut sleeve feeding mechanism 4 is working, the pulse electromagnet installed inside the vibration disk 4012 converts the pulse of electrical energy into mechanical pulsation, causing the vibration disk 4012 to perform torsional vibration, arranging the nut sleeves 10 neatly and transmitting them to the conveyor belt 402 through the pipe mouth of the conveying pipe 4011, and the conveyor belt 402 transports the nut sleeves 10 to the limiting groove 2011 of the workpiece carrier 2 in sequence.

[0027] When the nut feeding mechanism 6 is working, the vibration plate 4012 performs torsional vibration, arranges the nut 12 neatly and transmits it to the conveyor belt 402 through the pipe mouth of the conveying pipe 4011, and the conveyor belt 402 sequentially transports the nut 12 to the limiting groove 2011 of the workpiece carrier 2.

[0028] When the spring sheet feeding mechanism 5 is working, the vibration plate 4012 performs torsional vibration, so as to arrange the nut 12 neatly and transmit it to the conveyor belt 402 through the pipe opening of the conveying pipe 4011 .

[0029] In summary, the method of conveying the nut sleeve 10 by using the cooperation between the vibration feeding mechanism 401 and the conveyor belt 402 minimizes manual intervention, reduces labor costs, improves production efficiency, and ensures product quality.

Among them, the transverse drive mechanism includes a linear module 704 and a fixing block 705, the lifting drive mechanism includes a first cylinder 703 and a first connecting member 702, the loading mechanism 7 is installed on the right side of the spring sheet feeding mechanism 5, the first cylinder 703 and the linear module 704 are fixedly installed on the top of the bracket 15, the linear module 704 is fixedly connected to the first cylinder 703 through the fixing block 705, the bottom of the first cylinder 703 is fixedly connected to the first connecting member 702, and the bottom of the first connecting member 702 is fixedly connected to the clamping claw 701. The clamping jaw 701 includes a connecting arm 7011 and two clamping arms 7012 symmetrically arranged on the connecting arm. A clamping notch is arranged at the end of the clamping arm 7012. The clamping notch is the gap between two protrusions extending upward from the end of the clamping arm 7012, and the protrusions and the clamping notch are symmetrically distributed. The clamping notch matches the first protrusion 111 and the second protrusion 112 of the spring 11. In an optional embodiment, the interior of the clamping arm 7012 is provided with gaps that evenly divide the clamping notch, so as to increase the deformation capacity and ensure that the clamping jaw 701 can be easily removed after installation. It is worth noting that Figure 3 An optimal clamping jaw 701 is provided. Figure 9-10 Another type of clamp 701 is provided, and the type of clamp is not limited here and may be selected according to actual conditions.

[0031] In an optional embodiment, when the loading mechanism 7 is working, the linear module 704 at the top of the bracket 15 moves toward the direction of the conveyor belt 402. While the linear module 704 moves, the first cylinder 703 fixedly connected to one side of the linear module 704 by the fixed block 705 moves accordingly. When the clamp 701 is suspended above the conveyor belt 402, the first cylinder 703 starts to move downward until the clamp 701 clamps the spring piece 11; then, the first cylinder 702 moves upward and stops moving after reaching a preset height. Then, the linear module 704 moves toward the direction of the workpiece carrier 2 until the clamp 701 is located at the upper end of the workpiece carrier 2; then, the first cylinder 703 moves downward, and the clamp 701 inserts the clamped spring piece 11 into the nut sleeve 10 and then pulls out the clamp, completing the installation of the spring piece 11 and obtaining the semi-finished product 13 assembled with the nut sleeve and the spring piece, please refer to Fig.12, which is a structural schematic diagram of a semi-finished product of a nut sleeve and a spring assembly provided in an embodiment of the present application. In the figure, it can be seen that the protruding portion 111 and the second protruding portion 112 of the spring 11 are respectively stuck at the two driving ports 102 of the nut sleeve 10.

[0032] The pressing mechanism 9 includes a bracket 15, a second cylinder 901 and a pressing block 902. The second cylinder 901 is installed at the top of the bracket 15, and the bottom of the cylinder is connected to the pressing block 902 through a push-pull rod. The pressing block 902 is provided with a protrusion that matches the limit groove 2011. When working, the second cylinder 901 moves downward, driving the pressing block 902 at the bottom of the push-pull rod to move downward. The pressing block 902 uses the pressure provided by the second cylinder 901 to the pressing block 902 and the protrusion of the pressing block 902 itself to press the nut 12 into the semi-finished product 13 of the nut sleeve and the spring piece assembly to obtain the finished product 14, as shown in FIG. Fig.13 shown.

[0033] The working principle of the unloading and conveying mechanism 8 is similar to that of the loading mechanism 7, except that the workpieces clamped by the clamping jaws 701 are different. Specifically, the linear module 704 at the top of the bracket 15 moves toward the direction of the workpiece carrier 2, driving the first cylinder 703 to move accordingly. When the clamping jaws 701 are suspended above the workpiece carrier 2, the first cylinder 703 moves downward until the clamping jaws 701 clamp the finished product 14; then, the first cylinder 703 moves upward and stops moving after reaching a preset height. Then, the linear module 704 moves linearly toward the direction of the finished product frame until the clamping jaws 701 are located at the upper end of the finished product frame; finally, the first cylinder 703 moves downward, and the clamping jaws 701 insert the finished product 14 into the finished product frame and then withdraw it, thereby completing the conveying of the finished product 14.

[0034] The working principle of the present invention is: First, the vibration plate 4012 in the nut sleeve conveying mechanism 4 performs torsional vibration to convey the nut sleeves 10 to the conveying pipe 4011 in sequence, and the conveyor belt 402 receives the nut sleeves 10 at the mouth of the conveying pipe 4011 and conveys them to the limiting groove 2011 of the workpiece carrier 2; Furthermore, the driving mechanism 3 in the workbench 1 drives the turntable 16 to rotate, and the turntable 16 drives the workpiece carrier 2 fixed on the turntable 16 to rotate together, until the opening of the U-shaped groove 201 points to the outlet of the conveyor belt 402 in the spring sheet feeding mechanism 5; At the same time, the vibration feeding mechanism 401 in the spring feeding mechanism 5 vibrates to sequentially convey the spring pieces 11 inside to the conveying pipe 4011, and sequentially conveys them to the conveyor belt 402 through the pipe opening of the conveying pipe 4011; the loading mechanism 7 uses the clamping claw 701 to take out the spring pieces 11 placed in the conveyor belt 402 in the spring feeding mechanism 5, and installs it into the nut sleeve 10 placed in the workpiece carrier 2; Further, when the opening direction of the U-shaped groove 201 in the workpiece carrier 2 points to the conveyor belt 402 in the nut feeding mechanism 6, the nut feeding mechanism 6 sequentially conveys the internal nut 12 to the conveying tube 4011, receives the nut 12 through the tube mouth of the conveying tube 4011, and conveys the nut 12 to the limiting groove 2011 of the workpiece carrier 2; Further, when the workpiece carrier 2 on which the semi-finished product 13 of the nut sleeve and the spring sheet assembly and the nut 12 are placed rotates to the pressing mechanism 9, the pressing block 902 in the pressing mechanism 9 uses its own protrusion and the pressure provided by the second cylinder 901 to press the nut 12 into the semi-finished product 13 of the nut sleeve and the spring sheet assembly to obtain the finished product 14; Finally, when the workpiece carrier 2 with the finished product 14 rotates to the unloading conveying mechanism 8, the unloading conveying mechanism 8 uses the clamping claw 701 to take the finished product 14 out of the workpiece carrier 2, and then places the finished product 14 into the finished product frame. There is no requirement for the container for placing the finished product 14, which can be set according to actual conditions. In summary, the assembly of the drill chuck assembly is completed.

[0035] The present invention provides a semi-automatic assembly device for manufacturing a drill chuck assembly, which is intended to realize automatic assembly and autonomous transportation of a drill chuck. First, the present invention utilizes the mutual cooperation of a workbench 1, a nut sleeve feeding mechanism 4, a spring feeding mechanism 5, and a nut feeding mechanism 6 to automatically feed, replacing the traditional manual feeding, ensuring uniform feeding, and saving more time; secondly, utilizing an independently designed workpiece carrier 2 to automatically transport the workpieces completed by each mechanism, reducing manual intervention, ensuring the consistency of the feeding speed, improving production efficiency, and saving more effort; finally, utilizing a combination of a first cylinder 703 and a linear module 704 to control the movement of the clamping jaw 701, so that it can adapt to various installation conditions, ensuring the efficiency of the installation, and being faster. In summary, utilizing the present invention to assemble a drill chuck is more time-saving, more labor-saving, and faster.
