[0002] Mechanical manufacturing is a broad field that involves the design, production and maintenance of mechanical systems. It covers the manufacturing process from simple mechanical parts to complex mechanical equipment and systems. Mechanical manufacturing technology plays a vital role in modern industry and promotes the development of all walks of life.

[0003] A trolley is a commonly used feeding tool in machining operations. Generally, a cargo bucket is installed on the trolley, and the required workpieces can be placed inside the cargo bucket, thereby realizing the transfer and feeding of the workpieces.

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention 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 invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] See also Figures 1 to 8 , an embodiment of the present invention provides a feeding device for mechanical manufacturing, the feeding device for mechanical manufacturing comprising a cart 1, a conveyor belt 3, a fixing mechanism 4 and an external positioning frame 5;

[0040] A base frame 2 is fixed on the trolley 1. The base frame 2 includes a bottom plate. Two groups of symmetrically arranged mounting frames are fixed on the upper end of the bottom plate away from the center. The conveyor belt 3 is installed on the mounting frames. A plurality of insertion rods 21 are also fixed on the bottom plate away from the center.

[0041] The fixing mechanism 4 includes an adjusting portion 41 fixed on the conveyor belt 3 and a plurality of fixing portions 42 movably mounted on the adjusting portion 41. There is a gap between the conveyor belt 3 and the bottom plate. The height of the gap is greater than the height of the fixing mechanism 4. The conveyor belt 3 is divided into two symmetrical parts, the upper part is equipped with the fixing mechanism 4, and the lower part does not have the fixing mechanism 4:

[0042] See also Figure 5 and Figure 6The adjusting part 41 includes a base 411, which is cylindrical and bolted to the conveyor belt 3. The base 411 has a groove penetrating the lower end surface. The upper end of the conveyor belt 3 is provided with a plurality of annularly distributed and radially arranged positioning grooves 412. The bottom of the positioning groove 412 is provided with a strip slide 413 connected to the groove. A positioning rod 414 is fixed at the center of the inner top of the groove. A torsion spring 415 is fixed on the positioning rod 414. A positioning ring rail 416 is also fixed on the circumferential inner wall of the groove.

[0043] An adjusting disk 417 is rotatably connected inside the receiving groove and is arranged concentrically with the base 411. The adjusting disk 417 is provided with arc-shaped slideways 419 corresponding to the number and position of the strip slideways 413. A center hole 418 is also provided at the center of the adjusting disk 417. The positioning rod 414 extends into the center hole 418, and the torsion spring 415 presses against the adjusting disk 417. A positioning ring groove 4110 is provided on the circumferential outer wall of the adjusting disk 417, and the positioning ring rail 416 is embedded in the positioning ring groove 4110.

[0044] See also Figure 5 and Figure 7 The fixed portion 42 includes a slide 421, which slides inside the positioning slide groove 412. A transmission pin 423 is vertically fixed at the lower end of the slide 421. The transmission pin 423 passes through the strip slide 413 and extends to the inside of the arc slide 419. The force exerted on the transmission pin 423 by the rotation of the adjusting disk 417 drives each slide 421 to move radially synchronously. A clamping block 422 is also fixed on one side of the slide 421.

[0045] It should be noted that: in the device, the cart 1 is used as the main carrier, and the cart 1 is preferably electrically driven, so it will be more labor-saving and convenient in actual use;

[0046] The device preferably uses a rod-type workpiece, and the fixing mechanism 4 is set for this type of workpiece to fix the rod. There are multiple fixing mechanisms 4, and each fixing mechanism 4 fixes a rod separately, so that the rod-type workpieces can be placed separately, so as to ensure the stability of the rods during transportation operations, avoid collisions between the rods, and ensure the quality of the workpieces;

[0047] When fixing the rod, the operator holds the rod so that it is in a vertical state, with its lower end aligned with the position between the slides 421, and then the rod can be inserted between the slides 421. The upper end of the slide 421 has an inclined surface, which is the surface in contact with the rod. Therefore, when the rod is squeezed, the slide 421 moves synchronously toward a position away from the center of the base 411 until the rod contacts the base 411. In this process, the rod squeezes the slide 421 to overcome the elastic force of the torsion spring 415. After the placement is completed, the rod is clamped and fixed by the elastic force of the torsion spring 415 to complete the fixation of the rod.

[0048] Each slide 421 is distributed in a ring shape, and the driving pin 423 at the lower end thereof extends into the inside of the adjusting disk 417, so that each slide 421 is limited by the adjusting disk 417. When the adjusting disk 417 rotates, the slides 421 can move synchronously, so that each clamping block 422 can clamp the rod evenly, which has a better fixing effect on the rod and is very convenient for disassembling and assembling the rod.

[0049] For the installation of the adjusting disk 417, a positioning ring groove 4110 is provided on the outside thereof, and a positioning ring rail 416 is provided on the inner wall of the inner groove of the base 411. The positioning ring rail 416 is embedded in the positioning ring groove 4110 to achieve stable installation of the adjusting disk 417 without affecting the rotation of the adjusting disk 417.

[0050] The fixing mechanisms 4 are all installed on the conveyor belt 3, so the position of each row of fixing mechanisms 4 can be changed by rotating the conveyor belt 3, so that any row of fixing mechanisms 4 can be moved to the frontmost position of the cart 1. Therefore, after taking out the rods at the frontmost row, the conveyor belt 3 can be rotated to move the fixing mechanisms 4 at the next row to the frontmost position. Therefore, when taking and placing the rods, they can always be taken out from the frontmost position without having to walk back and forth to take them.

[0051] The conveyor belt 3 is divided into two symmetrical parts, one of which is equipped with a fixing mechanism 4, and the other is not equipped with a fixing mechanism 4. Therefore, when all the fixing mechanisms 4 are at the upper end of the conveyor belt 3, they can be used to fix the rods, and when all the fixing mechanisms 4 are at the lower end surface of the conveyor belt 3, the upper end surface of the conveyor belt 3 is a plane, and the outer positioning frame 5 can be disassembled. After disassembly, the upper end of the conveyor belt 3 does not have a restrictive structure, so it can also be used to place plate-like workpieces, thereby further improving the scope of application of the device.

[0052] See also Figure 8The outer positioning frame 5 includes a first support frame 51 near the rear end of the cart 1, and a second support frame 52 near the front end of the cart 1. The first support frame 51 and the second support frame 52 are both fixed to the bottom plate, and the height of the first support frame 51 is twice the height of the second support frame 52. Positioning brackets 53 are fixed on the first support frame 51 and the second support frame 52. A plurality of equally spaced baffles 54 are fixed between the two positioning brackets 53, and a channel for conveying rod materials is formed between adjacent baffles 54.

[0053] At the same time, a plug hole 56 is provided at the bottom of the first support frame 51 and the second support frame 52 , and the first support frame 51 and the second support frame 52 are fixed by inserting the plug rod 21 into the plug hole 56 .

[0054] It should be noted that: the outer positioning frame 5 has a first support frame 51 and a second support frame 52 of different heights, and a plurality of baffles 54 are arranged between the two. Therefore, there is a height difference between the first support frame 51 and the second support frame 52, and the baffle 54 close to the front end of the cart 1 is at a low position. Therefore, when the rod is in this position, the exposed part will be more, which is more convenient for operators to grab and install or take for use; at the same time, a channel is formed between adjacent baffles 54, and the rod is driven to move inside the channel by the conveyor belt 3. The baffle 54 can play a certain limiting role on the rod, and when the rod is skewed, it can prevent it from going off the track;

[0055] For the installation of the external positioning frame 5, there are sockets 56 at the bottom of the first support frame 51 and the second support frame 52, and a plurality of insertion rods 21 are arranged on the bottom plate, and the insertion rods 21 can be inserted into the sockets 56 to achieve the limitation of the first support frame 51 and the second support frame 52, thereby ensuring the stability of the entire external positioning frame 5, and at the same time, it is also relatively convenient to install and remove.

[0056] See also Figure 8 A row of guide frames 55 is also fixed on the positioning bracket 53 in the second support frame 52. The guide frames 55 are semi-annular, and in the vertical direction, the guide frames 55 can correspond concentrically to any row of fixing mechanisms 4.

[0057] It should be noted that the guide frame 55 is arc-shaped and is used to assist the installation of the rod. The guide frame 55 is concentric with the fixing mechanism 4 in the vertical direction. Therefore, when the rod is fixed, the rod contacts the inner ring surface of the guide frame 55. In this state, the rod and the fixing mechanism 4 are in a concentric corresponding state. Therefore, it is only necessary to press downward directly, which will make the fixation of the rod more convenient.

[0058] The specific use of the device is as follows:

[0059] When fixing the rod, the operator holds the rod so that it is in a vertical state, with its lower end aligned with the position between the slides 421, and then the rod can be inserted between the slides 421. The upper end of the slide 421 has an inclined surface, which is the surface in contact with the rod. Therefore, when the rod is squeezed, the slide 421 moves synchronously toward a position away from the center of the base 411 until the rod contacts the base 411. In this process, the rod squeezes the slide 421 to overcome the elastic force of the torsion spring 415. After the placement is completed, the rod is clamped and fixed by the elastic force of the torsion spring 415 to complete the fixation of the rod.

[0060] The fixing mechanisms 4 are all installed on the conveyor belt 3, so the position of each row of fixing mechanisms 4 can be changed by rotating the conveyor belt 3, so that any row of fixing mechanisms 4 can be moved to the front end position of the cart 1. Therefore, after taking out the rods at the front end row position, the conveyor belt 3 can be rotated to move the fixing mechanisms 4 at the back row position to the front end position. Therefore, when taking and placing the rods, they can always be taken out from the front end position without walking back and forth to take them.

[0061] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
