Description

Technical Field

[0001] The present invention relates to the technical field of workpiece loading, and particularly relates to a sheet metal part loading device. Background Art

[0002] In a factory, when processing and producing sheet metal parts, a chain conveyor is required to perform long-distance feeding and conveying of the sheet metal parts. The sheet metal parts are suspended on the hangers of the chain conveyor. During the conveying process of the sheet metal parts by the chain conveyor, they are prone to swing, which not only increases the danger level of the equipment, but also the swinging sheet metal parts will rub against the hangers, thereby wearing the hanging holes of the sheet metal parts, and thus affecting the quality of the sheet metal parts after processing and production. Summary of the Invention

[0003] The purpose of the present invention is to provide a sheet metal part loading device to overcome the above-mentioned defects in the prior art.

[0004] A sheet metal part loading device includes a chain conveyor. A plurality of hanging plates are evenly distributed below the chains of the chain conveyor. A hanger is provided at the lower end of each hanging plate. Limiting mechanisms for positioning the sheet metal parts are symmetrically provided on both sides of each hanger.

[0005] Preferably, the hanger includes a hook, a connecting plate and a connecting rod. Two hooks are provided and symmetrically arranged on both sides of the connecting plate. The connecting rod is vertically arranged on the connecting plate, and the top of the connecting rod is connected to the hanging plate.

[0006] Preferably, the limiting mechanism includes a spring and a limiting block. A fixing frame is vertically provided on the front side of each hook. An installation groove is provided on each fixing frame. A guide rod is slidably connected in the installation groove. A stop disk is provided on the guide rod in the installation groove. The spring is sleeved on the guide rod and is located between the inner wall of the installation groove and the stop disk. The guide rods between the two hooks of the same connecting plate are connected by a fixing rod. A limiting block is provided at the lower end of each guide rod. An inclined surface is provided on the front side of the limiting block.

[0007] Preferably, the lower end of the limiting block is a horizontal plane and a baffle for blocking the sheet metal part is provided on its inner side.

[0008] Preferably, the fixing rod is of a "U" - shaped structure with its opening facing downwards.

[0009] Preferably, a rubber sleeve is provided in the middle of the fixing rod.

[0010] Preferably, the connecting rod is detachably connected to the hanging plate by a plurality of bolts.

[0011] Preferably, a weight - reducing hole is provided at the rear side of each fixing frame.

[0012] The beneficial effects achieved by the present invention are:

[0013] The present application uses a hook on a sling of a chain conveyor to suspend the sheet metal. During the slinging process, the limit block is squeezed upward by the inclined surface of the limit block. When the sheet metal is at the bottom of the limit block, the sheet metal is pressed down and fixed by a spring. The baffle on the side of the limit block limits the sheet metal, so that the limit plate automatically fixes the sheet metal, preventing the sheet metal from shaking randomly during the movement of the chain conveyor and preventing the lifting holes of the sheet metal from being worn on the sling.

DETAILED DESCRIPTION

[0020] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention.

[0021] like Figure 1-5 As shown, the present invention provides a sheet metal feeding device, including a chain conveyor 1, wherein a plurality of hanging plates 2 are evenly distributed under the chain of the chain conveyor 1, a hanger 3 is provided at the lower end of each hanging plate 2, and limiting mechanisms 4 for positioning sheet metal parts 5 are symmetrically provided on both sides of the hanger 3.

[0022] It should be noted that the lifting tool 3 includes a hook 31, a connecting plate 32 and a connecting rod 33. There are two hooks 31, which are symmetrically arranged on both sides of the connecting plate 32. The connecting rod 33 is vertically arranged on the connecting plate 32. The top of the connecting rod 33 is detachably connected to the lifting plate 2 through a plurality of bolts, so as to facilitate the disassembly and assembly of the lifting tool.

[0023] In addition, the limiting mechanism 4 includes a spring 42 and a limiting block 45. A fixing frame 41 is vertically arranged on the front side of each hook 31. A weight-reducing hole is arranged on the rear side of each fixing frame 41. An installation groove 411 is arranged on each fixing frame 41. A guide rod 47 is slidably connected in the installation groove 411. A retaining disc 43 is arranged on the guide rod 47 in the installation groove 411. The spring 42 is sleeved on the guide rod 47 and is located between the inner wall of the installation groove 411 and the retaining disc 43. The guide rods 47 on the two hooks 31 of the same connecting plate 32 are connected by a fixing rod 44. The fixing rod 44 is of a "U" - shaped structure and its opening faces downward. A rubber sleeve 441 is arranged in the middle of the fixing rod 44, so as to make the fixing rod 44 anti - slip when being pulled;

[0024] A limiting block 45 is arranged at the lower end of each guide rod 47. An inclined surface 451 is arranged on the front side of the limiting block 45. The lower end of the limiting block 45 is a horizontal surface 452 and a baffle 46 for blocking the sheet metal part 5 is arranged on the inner side thereof. The sheet metal part is limited by the baffle 46.

[0025] Specific implementation methods and principles:

[0026] S1. During use, the sheet metal part 5 is installed on the two hooks 31 of the lifting tool 3 through the lifting holes on both sides of the sheet metal part 5;

[0027] S2. Then, the sheet metal part 5 is moved downward on the hook 31. The sheet metal part 5 squeezes the limiting block 45 through the inclined surface 451 on the front side of the limiting block 45, and the spring 42 on the guide rod 47 is compressed;

[0028] S3. When the sheet metal part 5 moves downward to the horizontal surface 452 at the bottom of the limiting block 45, the sheet metal part 5 is limited by the elastic force of the spring 42. At the same time, the baffle 46 on the side of the limiting block 45 blocks the sheet metal part 5 to prevent the sheet metal part 5 from moving randomly;

[0029] S4. The chain conveyor 1 drives the sheet metal part 5 to be transported to the processing station for corresponding processing;

[0030] S5. When it is necessary to remove the sheet metal part 5 from the hook 31, only need to pull the fixing rod 44 upward to separate the limiting block 45 from the sheet metal part 5, then the sheet metal part 5 can be removed from the hook 31.

[0031] To summarize, the present application hangs the sheet metal part 5 through the hook 31 on the hanger 3 of the chain conveyor 1. During the hanging process of the sheet metal part 5, the limit block 45 is squeezed upward by the inclined surface 451 of the limit block 45. When the sheet metal part 5 is located at the bottom of the limit block 45, the sheet metal part 5 is pressed down and fixed by the spring 42, and the baffle 46 on the side of the limit block 45 limits the sheet metal part 5, so that the limit plate automatically fixes the sheet metal part 5, preventing the sheet metal part 5 from shaking randomly during the movement of the chain conveyor 1, and preventing the hanging hole of the sheet metal part 5 from being worn on the hanger 3.

[0032] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
