Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to a CNC hopper expansion mechanism. Background Technology

[0002] In the field of CNC machining, with the continuous improvement of manufacturing automation and the increasing diversification of production demands, the requirements for workpiece storage are also increasing. Traditional CNC material storage structures are usually relatively simple, with limited storage capacity, making it difficult to meet the needs of large-scale production or simultaneous storage of multiple types of workpieces.

[0003] In actual production, when production tasks increase or the types of workpieces increase, the limited silo space will lead to chaotic workpiece storage. Frequent workpiece replacement and handling will not only reduce production efficiency, but also easily cause quality problems due to operational errors. For example, in batch production mode, workpieces need to be frequently moved in and out of the silo. If the silo capacity is insufficient, multiple shutdowns are required to replace workpieces, which seriously affects the production schedule. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a CNC silo expansion mechanism.

[0005] This utility model proposes a CNC silo expansion mechanism, including an equipment cabinet and a frame installed outside the equipment cabinet. A lower silo module and a middle silo module are respectively installed on the top of the equipment cabinet, and an upper silo module is installed on the top of the frame. The lower, middle, and upper silo modules are arranged in a stacked distribution, and the size of the silo plates of the lower, middle, and upper silo modules gradually increases. Each of the lower, middle, and upper silo modules is equipped with a driving device to allow the silo plates of the lower, middle, and upper silo modules to move independently back and forth.

[0006] Furthermore, the lower silo module, the middle silo module, and the upper silo module all include a rodless cylinder and a linear guide rail. The upper part of the linear guide rail is slidably connected to the silo base. The drive end of the rodless cylinder is connected to the silo base. The silo plate is fixed inside the silo base.

[0007] Furthermore, the lower silo module, the middle silo module, and the upper silo module also include proximity switches, which are symmetrically arranged at both ends of one of the linear guide rails.

[0008] Furthermore, the lower silo module, the middle silo module, and the upper silo module also include a hydraulic damper, which is located at the end of the silo base's moving path to reduce the kinetic energy of the silo base moving to the end.

[0009] Furthermore, several positioning protrusions are installed at the bottom of the inner side of the hopper base, and several positioning holes are symmetrically opened on the edge of the hopper plate. The positioning protrusions are adapted to the positioning holes, the hopper plate is located inside the hopper base, and the positioning protrusions are inserted into the positioning holes.

[0010] Furthermore, several workpiece slots are formed on the upper surface of the silo plate, and the number of workpiece slots formed on the silo plates in the lower silo module, middle silo module, and upper silo module gradually increases.

[0011] The beneficial effects of this utility model are as follows: by stacking lower, middle and upper hopper modules and increasing the size of each hopper plate layer by layer, the storage capacity is significantly expanded in a limited space, which can accommodate more workpieces of different sizes and quantities, effectively avoids frequent downtime for material replacement due to insufficient hopper capacity, and greatly improves the production efficiency of CNC machining.

[0017] Reference Figure 1-4 The present invention proposes a CNC silo expansion mechanism, which mainly consists of an equipment cabinet 1, a frame 2, a lower silo module 3, a middle silo module 4, and an upper silo module 5, as detailed below:

[0018] Place the equipment cabinet 1 in the designated working position for CNC machining. Then, install the frame 2 on the outside of the equipment cabinet 1 with bolts. Install the lower hopper module 3 and the middle hopper module 4 on the top of the equipment cabinet 1. At the same time, install the upper hopper module 5 on the top of the frame 2. At this time, the lower hopper module 3, the middle hopper module 4 and the upper hopper module 5 form a stacked structure with a gap between them.

[0019] The lower hopper module 3, the middle hopper module 4, and the upper hopper module 5 have the same structure, except that the size of the hopper plates 44 they contain gradually increases from bottom to top. This design is to achieve better overall capacity expansion within a limited space, so as to accommodate more workpieces. The structure of the middle hopper module 4 will be described in detail below:

[0020] The middle-layer hopper module 4 consists of a rodless cylinder 41, a linear guide rail 42, a hopper base 43, a hopper plate 44, a proximity switch 45, a hydraulic damper 46, a positioning protrusion 47, a positioning hole 48, and a workpiece groove 49. Specifically:

[0021] The rodless cylinder 41 and the linear guide rail 42 are both bolted to the top of the equipment cabinet 1. The upper part of the linear guide rail 42 is slidably connected to the hopper base 43, and the hopper plate 44 is locked and fixed inside the hopper base 43.

[0022] The drive end of the rodless cylinder 41 is connected to the hopper base 43 through a connector. When the rodless cylinder 41 works, its drive end drives the hopper base 43 to reciprocate along the linear guide rail 42. By controlling the action of the rodless cylinder 41, the hopper plates of the lower hopper module 3, the middle hopper module 4, and the upper hopper module 5 can reciprocate independently to meet the requirements for picking up and putting down workpieces.

[0023] In each hopper module, proximity switches 45 are symmetrically arranged at both ends of one of the linear guide rails 42. The function of proximity switches 45 is to detect the position of hopper base 43. When hopper base 43 moves into the sensing range of proximity switch 45, proximity switch 45 will send a signal to the control system, thereby realizing precise control of the movement position of hopper base 43 and preventing hopper base 43 from exceeding the normal movement range. This is existing known technology and will not be described in detail here.

[0024] The hydraulic buffer 46 is located at the end of the moving path of the hopper base 43. When the hopper base 43 moves to the end, it will abut against the buffer end of the hydraulic buffer 46. The hydraulic buffer 46 reduces the kinetic energy of the hopper base 43 moving to the end through the internal hydraulic damping effect, preventing the hopper base 43 from violently colliding with the end structure due to excessive inertia, thus protecting the equipment and improving the stability of operation. The specific structure of the hydraulic buffer 46 and how to achieve buffering are existing known technologies and will not be described in detail here.

[0025] Several positioning protrusions 47 are installed at the bottom of the inner side of the hopper base 43. Several positioning holes 48 are symmetrically opened on the edge of the hopper plate 44. The size and position of the positioning holes 48 are adapted to the positioning protrusions 47. When installing the hopper plate 44, the hopper plate 44 is placed inside the hopper base 43, so that the positioning protrusions 47 are inserted into the positioning holes 48, thereby realizing the quick and accurate connection between the hopper plate 44 and the hopper base 43. This connection method is not only convenient to install, but also ensures the stability of the position of the hopper plate 44 in the hopper base 43, and prevents the hopper plate 44 from shaking during the movement of the hopper base 43.

[0026] The upper surface of the hopper plate 44 has several workpiece slots 49. The number of workpiece slots 49 in the hopper plate 44 of different hopper modules gradually increases. This design further optimizes the storage function of the hopper, improves space utilization, and meets the needs for workpiece storage.

[0027] When the mechanism is in operation, it integrates the drive devices of the aforementioned hopper modules, proximity switches 45, and other components with the control system. The control system can adopt a PLC programmable logic controller or other suitable control equipment. By writing corresponding control programs, it realizes the motion control of the rodless cylinder 41, and precisely controls the moving position and moving speed of each hopper plate according to production needs. At the same time, the signals fed back by the proximity switches 45 are transmitted to the control system. The control system adjusts the operating status of each hopper module in real time according to these signals to ensure the safe and stable operation of the entire CNC hopper expansion mechanism. The control structure, circuit structure, and programming content of the control system and the connection of each component are all technical contents well known to those skilled in the art, and will not be described in detail here.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
