Description

Technical Field

[0001] The utility model relates to the technical field of feeding shaft parts, in particular to a shaft-penetrating feeding mechanism. Background Art

[0002] Shaft parts are one of the typical parts often encountered in hardware accessories. They are mainly used to support transmission parts, transmit torque and bear loads. According to the different structural forms of shaft parts, they can generally be divided into three categories: smooth shafts, stepped shafts and special-shaped shafts, or divided into solid shafts and hollow shafts. They are used in machines to support transmission parts such as gears and pulleys to transmit torque or motion. Shaft parts are rotating parts with a length greater than the diameter. They are generally composed of the outer cylindrical surface, conical surface, inner hole and thread of the concentric shaft and the corresponding end face. According to the different structural shapes, shaft parts can be divided into smooth shafts, stepped shafts, hollow shafts and crankshafts. At present, in the automatic feeding process of hollow shaft parts, a picking mechanism grabs the hollow shaft parts at a fixed position, and a fixed number of hollow shaft parts are mounted on the guide shaft. When the picking mechanism has taken all the hollow shaft parts on the guide shaft, the picking process needs to be suspended. The picking mechanism can only pick up materials again after the addition of hollow shaft parts is completed. In addition, the process of replenishing hollow shaft parts needs to be handled manually, the degree of automation is low, and the frequency of replenishment is high. Utility Model Content

[0017] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0018] Figure 1 The overall structure of the through-axis feeding mechanism is schematically shown. Figure 1 As shown, it includes a rotating table 1 and a plurality of loading tools movably fixed on the rotating table 1. The rotating table 1 is driven by a transmission mechanism. Figure 2 The overall structure of the loading tooling is shown schematically. Figure 2 As shown, the aforementioned loading tooling includes a base 3, a guide shaft 4 and a slider 5. A plurality of through holes penetrating the thickness direction of the rotating table 1 are opened, and the base 3 is fixed on the rotating table 1 by means of the through holes. The guide shaft 4 is embedded in the base 3, and the guide shaft 4 is locked in the base 3 by means of a quick latch extending into the side of the base 3. A slider 5 is sleeved on the guide shaft 4, and an oil-free bushing is provided inside the slider 5. Based on the aforementioned slider 5, the product is sleeved on the guide shaft 4 in a stacked manner, and a detection component is used to detect the position and quantity of the products on the guide shaft 4 to determine whether the loading tooling needs to be replaced.

[0019] The aforementioned base 3 is fixedly arranged at equal intervals based on the outer edge of the rotating table 1, and a fixed table 2 is arranged inside the rotating table 1. The rotating table 1 rotates relative to the fixed table 2. The rotating table 1 can rotate relative to the fixed table 2 by means of bearings, and the detection component is fixedly arranged on the fixed table 2.

[0020] The detection component is described in detail below. The detection component includes a plurality of fixed rods 7 vertically fixed on the fixed platform 2, and a first sensor 8 and a second sensor 9 are fixedly arranged on the fixed rods 7. The first sensor 8 is fixedly arranged on the top of the fixed rods 7 to detect whether there is a product at the material taking position, and the second sensor 9 is fixedly arranged on the bottom of the fixed rods 7 to detect whether there is a product on the slider 5. The first sensor 8 and the second sensor 9 are used to detect the position of the product on the guide shaft 4. When there are two fixed rods 7, the angle between the first sensor 8 or the second sensor 9 fixed on the fixed rods 7 is the same as the angle between the adjacent guide shafts 4, so that the first sensor 8 or the second sensor 9 fixed on the fixed rods 7 can detect the number and position of products on the adjacent fixed rods 7, thereby determining whether manual feeding is required.

[0021] In actual use, the product is manually put on the guide shaft 4, and then the guide shaft 4 is inserted on the base 3 and fixed with the quick release pin 6. When automatically picking up materials, the slider 5 located on the turntable station is lifted up by the fork, so that the parts worn on the guide rise, and the picking mechanism can grab the parts at the same position (i.e., the picking position) every time. After the products at the current station are picked up, the turntable automatically switches to the next station, and the cycle is repeated. After the empty station runs to the rear end, it is manually replenished, which can meet the demand of loading once every ninety minutes at most.

[0022] The aforementioned transmission mechanism includes a divider 10 and a motor assembly 11 for driving the divider 10. The divider 10 and the motor assembly 11 are fixedly arranged below the workbench and the rotating table 1. The motor assembly 11 drives the input shaft of the divider 10, and its output shaft is used to control the rotation of the rotating table 1. The number of loading fixtures is set according to the dividing angle of the divider 10. When the motor assembly 11 drives the divider 10 to rotate, it can correspondingly drive the rotating table 1 to rotate, thereby completing the replacement of the loading station. It is worth mentioning that, in order to save space, a gear set can be provided between the motor assembly 11 and the divider 10 for reversing, and a gear set for reversing can also be provided between the rotating table 1 and the output shaft of the divider 10.

[0023] Figure 3 The top view of the through-axis feeding mechanism is schematically shown. Figure 3As shown, a measured unit 13 is fixedly provided on the side of the base 3 facing the fixed table 2, and the measured units 13 on any base 3 are different. A positioning unit 12 for positioning the base 3 is fixedly provided on the side of the fixed table 2 facing the rotating table 1. The material picking process is carried out at the position of the positioning unit 12, and the positioning unit 12 and the measured unit 13 are aligned to complete the positioning of the loading tooling, wherein the measured units 13 of each loading tooling are different, which can be reflected as different positions and numbers of measured objects in the actual application process. The number and position of the measured objects detected by the positioning unit 12 are used to determine how many loading tools need to be manually replenished during the current loading process, and the collaborative detection component completes the manual replenishing process to ensure the automation and continuity of the loading process.

[0024] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
