[0027] Example

[0028] On the one hand, the height of the conveying mechanism is not convenient to adjust, so it cannot meet the different height requirements of external processing equipment;

[0029] Secondly, during the conveying process, it is necessary to manually fix the sheet metal parts on the conveying seat 5 through a clamp, and then start the conveying mechanism to convey the sheet metal parts. When the sheet metal parts are processed, it is necessary to manually loosen the clamp, resulting in low conveying efficiency.

[0030] To do this, see Figure 1-5 The utility model provides a sheet metal conveying mechanism using a guide rail, comprising: a conveying platform 1, a height-adjustable support structure 2 is installed at the bottom end of the conveying platform 1, and the height-adjustable support structure 2 is used to adjust the height of the conveying mechanism to adapt to the external sheet metal processing equipment;

[0031] The top of the conveying platform 1 is fixedly connected with an annular guide rail seat 3, and a plurality of conveying seats 5 distributed along the annular guide rail seat 3 are connected to the conveying platform 1 through a transmission structure 4. A protrusion 51 for placing an L-shaped sheet metal part is fixedly connected to the middle of the top of each conveying seat 5, and two symmetrically arranged guide wheels 44 are rotatably connected to the bottom end of each conveying seat 5. The inner and outer side walls of the annular guide rail seat 3 are provided with rolling tracks for facilitating the rolling of the guide wheels 44, and the bottom end of each conveying seat 5 is movably fitted to the top of the annular guide rail seat 3;

[0032] A synchronous conveying clamping and loosening structure 6 is connected between the multiple conveying seats 5 and the conveying platform 1. The synchronous conveying clamping and loosening structure 6 can automatically clamp or loosen the L-shaped sheet metal when the transmission structure 4 conveys the multiple conveying seats 5 to move along the annular guide rail seat 3.

[0033] Further Figure 1-2As shown, it is worth explaining in detail that, in order to facilitate the adjustment of the height of the conveying mechanism to meet the different height adaptation of external processing equipment, the adjustable height support structure 2 includes support inner rods 21 fixed all around the bottom end of the conveying platform 1, and the outer sides of the support inner rods 21 are movably sleeved with support outer rods 22, and the four support outer rods 22 are fixed to each other through connecting rods, and one side wall of the four support outer rods 22 is threadedly penetrated with a hand screw 23, and one end of the hand screw 23 after being locked is pressed against the outer side of the support inner rod 21.

[0034] The length of the supporting outer rod 22 is equal to the length of the supporting inner rod 21 , and a moving channel matching with the supporting inner rod 21 is provided on the inner side of the supporting outer rod.

[0035] Further Figure 1-5 As shown, it is worth explaining in detail that in order to facilitate the intermittent transportation of sheet metal parts on multiple conveying seats 5 to the processing stations of the processing equipment, a transmission structure 4 is set up, including two symmetrically arranged rotating shafts rotatably connected on the conveying platform 1, and the outer sides of the top ends of the rotating shafts are fixedly connected with pulleys a41, and a transmission belt 42 is connected for transmission between the two pulleys a41. The top end of the transmission belt 42 is fixedly connected with a plurality of connecting columns 43 distributed in an array along the transmission belt 42, and the top ends of the connecting columns 43 are fixedly connected to the bottom edge of the conveying seat 5, and the bottom end of one of the rotating shafts extends to the bottom of the conveying platform 1 and is fixedly connected to the output shaft of the stepper motor 45, and the stepper motor 45 is fixedly connected to the bottom end of the conveying platform 1.

[0036] Among them, as attached Figure 1 As shown in the figure, a single conveyor table 1 near the middle of the rear side wall of the conveyor table 1 can be set as a processing station of an external processing equipment, and a processing device on the processing equipment of the prior art is used to perform processing operations on it. However, the stepper motor 45 can drive the sheet metal parts on each conveyor seat 5 for intermittent transportation, which is beneficial to greatly improve the production capacity and has a good use effect.

[0037] Further Figure 3-5As shown, it is worth specifically explaining that in order to enable the sheet metal placed on the top of the workbench on each conveying seat 5 to be automatically loosened or clamped, a conveying synchronous clamping and loosening structure 6 is set, including two symmetrically arranged clamping plates 61 sliding on the top of each conveying seat 5, and the bottom ends of the clamping plates 61 are fixed with sliders 62 with convex structures in vertical cross-section, and the sliders 62 are slidably connected to the slide grooves provided at the top of the conveying seat 5. The two clamping plates 61 provided at the top of each conveying seat 5 are hinged with push-pull rods 63 on the opposite side walls. , and the opposite ends of each pair of push-pull rods 63 are hinged to the top of the U-shaped transmission rod 64, the vertical cross-sections at both ends of each U-shaped transmission rod 64 are I-shaped structures, and each conveying seat 5 is provided with two movable channels that cooperate with the U-shaped transmission rod 64. The bottom end of each U-shaped transmission rod 64 is fixedly connected to a transmission column 65 at a position away from the conveying seat 5. The top of the conveying platform 1 is fixedly connected to an annular transmission seat 66, and a transmission channel 67 is provided on the top of the annular transmission seat 66. Each transmission column 65 is movably overlapped in the transmission channel 67.

[0038] As can be seen in the accompanying drawings, an arched portion is provided in the middle of the front side of the annular transmission seat 66. The arched portion can cooperate with the function of the transmission column 65 to realize the forward movement of the U-shaped transmission rod 64, so that the two clamping plates 61 are pushed open by the push-pull rod 63 respectively, thereby realizing the loosening of the sheet metal parts. This position can be set as a manual material placement station to facilitate manual picking up of processed sheet metal parts or placement of new sheet metal parts to be processed.

[0039] In summary: when the sheet metal conveying mechanism utilizing the guide rail type is used, the sheet metal can be placed on the workbench on the top of each conveying seat 5 at the above-mentioned manual material placement and unloading station, and by starting the stepper motor 45 and cooperating with the action of multiple components, the multiple conveying seats 5 are prompted to move around along the annular guide rail seat 3. In addition, each transmission column 65 will move in the transmission channel 67 provided on the top of the annular transmission seat 66. However, when the transmission column 65 leaves the arched portion, each U-shaped transmission rod 64 will move in the direction close to the transmission belt 42, and cooperate with the action of the push-pull rod 63 to make the two clamping plates 61 move relative to each other, and can actively realize the clamping and fixing of the L-shaped sheet metal. After the L-shaped sheet metal on the conveying seat 5 is processed by the external processing equipment at the processing station, it returns to the manual material placement and unloading station again, and can realize its automatic loosening and unloading.

[0040] In summary, the conveying mechanism enables the L-shaped sheet metal placed on the top protrusion 51 of each conveying seat 5 to be automatically clamped or loosened during the conveying process, without the need for manual clamping and fixing by manually operating the clamp, thereby greatly improving the efficiency of conveying to meet the needs of improving the processing efficiency of subsequent external processing equipment.

[0041] The stepper motor 45 can be purchased on the market. The stepper motor 45 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
