Automatic feeding and discharging device for mechanical parts

Abstract

This utility model provides an automatic loading and unloading device for mechanical parts, relating to the field of machining. It includes a limiting component, which consists of a baffle mechanism and a side plate mechanism. The mounting component enables automatic loading and unloading of material boxes, facilitating machining and improving processing efficiency. Furthermore, the limiting component limits and guides the number of material boxes fed, ensuring that only one material box is pushed out for loading at a time. This makes it convenient and flexible to use, and can adapt to the single-pushing loading of material boxes of different heights. It solves the problem that in the previous automatic loading and unloading device for mechanical parts, the lack of a limiting structure for the number of material boxes pushed out during loading caused multiple material boxes to be pushed out together due to friction and other factors, affecting normal processing and requiring manual correction.

Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an automatic loading and unloading device for mechanical parts. Background Technology

[0002] In the field of robotic machining and manufacturing, the efficient processing and production of mechanical parts cannot be separated from the assistance of automated equipment, and automatic loading and unloading devices play a crucial role in this process. These devices can replace manual labor, quickly and accurately placing the parts to be processed into the designated positions on the processing equipment, and promptly removing the finished products after processing. For example, patent application number CN201410700315.7 discloses an automatic loading and unloading device for parts, in which a feeding cylinder and a discharging cylinder are installed on the surface of the worktable. The piston rod of the feeding cylinder... The material box at the bottom of the storage chamber is pushed to the stroke position of the discharge cylinder. The piston rod of the discharge cylinder pushes the material box out of the worktable. A housing for the motor is located on the outer side of the material box sliding out of the worktable. The motor drives the lead screw to rotate up and down via a reducer. The front end of the lead screw inserts into the inner ring of the bearing in the lifting platform, causing the lifting platform to move up and down. Multiple guide rods are installed in the lifting platform and inserted into the housing. Feed sensors and discharge sensors are respectively installed on the surface of the worktable corresponding to the stroke positions of the feeding and discharge cylinders. A lifting sensor is installed on the sliding out side wall of the material box on the worktable. This invention achieves automatic loading and unloading of parts, ensuring good consistency of processed parts, avoiding operational errors caused by manual loading and unloading, reducing labor intensity, and improving production efficiency.

[0003] As with the existing automatic loading and unloading devices for mechanical parts, there is no limit structure for the number of boxes pushed during the loading process. This means that during feeding, multiple boxes can easily be pushed out together due to friction and other factors, affecting normal processing and use. Manual correction is still required, resulting in poor flexibility and low practicality. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please refer to Figures 1 to 7 Example 1:

[0029] This utility model proposes an automatic loading and unloading device for mechanical parts, comprising: an installation component 1 and a limiting component. The installation component 1 includes a worktable 101, a feeding cylinder 102, a discharging cylinder 103, and a lifting platform 104. The feeding cylinder 102 and the discharging cylinder 103 are respectively fixedly installed on both sides of the top of the worktable 101, and the lifting platform 104 is installed on the opposite side of the discharging cylinder 103 on the worktable 101. The installation component 1 can realize the automatic loading and unloading function of the material box during the machining process. After the workpieces to be processed are placed in the material box, the material box is stacked. On the side of the feeding cylinder 102, during machining, the feeding cylinder 102 can push the bottom material box, so that the bottom material box will automatically enter the processing area for processing. At the same time, the top material box can fall under its own weight, so as to prepare for subsequent feeding. After the material box is processed, it is pushed to the lifting platform 104 by the discharge cylinder 103. After a single material box enters the lifting platform 104, the lifting platform 104 will automatically move down so that the material boxes can be stacked after processing. It is convenient and flexible to use and has a high degree of automation.

[0030] The limiting assembly consists of a baffle mechanism 2 and a side plate mechanism 3;

[0031] The baffle mechanism 2 includes a support column 201, a feeding baffle 202, a positioning rod 203, and an adjusting rod 204. The support column 201 is fixedly installed on the top of the workbench 101, and the feeding baffle 202 is inserted into the side of the support column 201. The positioning rod 203 is rotatably connected inside the support column 201, and the adjusting rod 204 is rotatably connected inside the feeding baffle 202. The side plate mechanism 3 includes a synchronizing rod 301 and two track plates 302. The synchronizing rod 301 is rotatably connected inside the workbench 101, and the two track plates 302 are symmetrically inserted into the top of the workbench 101.

[0032] The positioning rod 203 has threads on its outer surface and is screwed into the inside of the feeding baffle 202. In use, the baffle mechanism 2 can push only one material box at a time for feeding. The feeding baffle 202 can block the sides of the material boxes, ensuring that only the bottom unblocked box is pushed by the feeding cylinder 102. The top box will not move synchronously with the bottom box due to friction, ensuring stable operation. Furthermore, the bottom limit height of the feeding baffle 202 can be adjusted via the adjusting rod 204, allowing for feeding of boxes of different heights. The adjustment rod 204 has a driving rod 2041 with a regular polygonal cross-section at its bottom, and the positioning rod 203 has a driving groove 2031 inside. The driving rod 2041 is inserted into the driving groove 2031. When the adjustment rod 204 is rotated, the driving rod 2041 of the adjustment rod 204 can drive the positioning rod 203 to rotate through the driving groove 2031. When the positioning rod 203 rotates, it can drive the feeding baffle 202 to move up and down on the side of the support column 201 through the rod thread, thereby changing the open space at the bottom of the feeding baffle 202, that is, the maximum limit height when a single material box is pushed out. It is convenient to adjust and flexible to use.

[0033] The side plate mechanism 3 also includes a positioning bolt 303, the nut of which is slidably connected to the inside of the worktable 101. The rod of the positioning bolt 303 passes through the inside of one of the track plates 302, and a nut is threaded onto the outside of the positioning bolt 303. During use, the side plate mechanism 3 ensures that the material boxes can be stably stacked inside, thus preventing tilting or twisting and ensuring the stable and efficient automatic feeding function. The spacing between the two track plates 302 is adjustable to accommodate the limiting use of material boxes of different widths. When the screw is loosened... When the timing is correct, both the positioning bolt 303 and the track plate 302 can move on the top of the workbench 101. The outside of the synchronization rod 301 is provided with a spiral synchronization groove 3011, and the bottom of the track plate 302 is provided with a synchronization protrusion 3021. The synchronization protrusion 3021 is inserted into the inside of the synchronization groove 3011. Under the cooperation of the synchronization protrusion 3021 and the synchronization groove 3011, the two track plates 302 can move synchronously in opposite directions, ensuring that their limit center is in the position of the feeding cylinder 102. The adjustment is convenient, and after the adjustment is completed, the track plate 302 can be locked again with a nut.

[0034] The working principle of this embodiment is as follows: The mounting component 1 enables automatic loading and unloading of the material boxes during machining. After the workpieces to be processed are stacked in the material boxes, the boxes are placed on the side of the feeding cylinder 102. During machining, the feeding cylinder 102 pushes the bottommost material box, causing it to automatically enter the processing area for processing. Simultaneously, the top material boxes fall under their own weight, ready for subsequent loading. After processing, the finished material boxes are pushed onto the lifting platform 104 by the discharge cylinder 103. After the material box enters the lifting platform 104, the lifting platform 104 automatically moves down so that the material boxes can be stacked after processing. The baffle mechanism 2 can realize the function of pushing only one material box at a time for feeding operation. The feeding baffle 202 can block the side of the material box, so that only the bottom material box that is not blocked can be pushed by the feeding cylinder 102. The top material box will not move synchronously with the bottom material box due to friction or other factors, which is stable. The bottom limit of the feeding baffle 202 can be adjusted by the adjusting rod 204. The height of the material box is adjusted to accommodate the limiting feeding function for boxes of different heights. When the adjusting rod 204 is rotated, the driving rod 2041 of the adjusting rod 204 can drive the positioning rod 203 to rotate through the driving groove 2031. When the positioning rod 203 rotates, it can drive the feeding baffle 202 to move up and down on the side of the supporting column 201 through the rod thread, thereby changing the open space at the bottom of the feeding baffle 202, that is, the maximum limiting height when a single box is pushed out. The side plate mechanism 3 can ensure that the boxes can be stably stacked inside, thereby preventing the boxes from tilting. The system eliminates tilting and twisting, ensuring the stability and efficiency of the automatic feeding function. The spacing between the two track plates 302 is adjustable, allowing for the use of limiters for material boxes of different widths. When the nuts are loosened, both the positioning bolts 303 and the track plates 302 can move on top of the worktable 101. With the cooperation of the synchronous protrusions 3021 and the synchronous grooves 3011, the two track plates 302 can move synchronously in opposite directions, ensuring that their limit centers are located at the position of the feeding cylinder 102. The adjustment is convenient, and the track plates 302 can be tightened again with nuts after adjustment.
