Description

Technical Field

[0001] This utility model belongs to the field of motor shaft processing technology, and in particular relates to a CNC milling machine for motor shaft production and processing. Background Technology

[0002] In the machining of precision shaft parts such as motor shafts, traditional milling machines generally suffer from problems such as low positioning accuracy, low automation, cumbersome operation, and low machining efficiency. Early conventional milling machines relied heavily on manual adjustment of workpiece position and manual control of feed, which was not only labor-intensive but also failed to meet the demands of modern industry for high-precision, high-volume production. With the development of CNC technology, some companies have begun to use CNC milling machines for machining motor shafts. While this has improved machining accuracy and automation to some extent, problems remain, including complex equipment structure, high maintenance costs, and limited specialization.

[0003] Furthermore, in actual machining, the clamping stability of the workpiece directly affects the machining quality. However, existing equipment often lacks sufficient rigidity and adjustment flexibility in the design of the clamping mechanism, which can easily cause workpiece displacement or vibration, affecting machining accuracy and safety. At the same time, if the metal shavings generated during machining are not cleaned up in time, they will not only affect subsequent machining processes but may also interfere with equipment operation and increase maintenance difficulty.

[0004] Therefore, there is an urgent need for a dedicated CNC milling machine with a reasonable structure, stable clamping, easy chip removal, and high-precision adjustment function to solve the above problems. To this end, we provide a CNC milling machine for motor shaft production to address these issues. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a CNC milling machine for manufacturing motor shafts, comprising a frame, a position adjustment assembly disposed on the upper part of the frame, and a machining assembly adapted to the position adjustment assembly. The frame includes a machine frame, a perforated panel laid flat inside the machine frame, and a collection bin disposed below the perforated panel. The position adjustment assembly includes a machine cover fixed to the upper side edge of the machine frame, a support plate installed inside the machine cover via a longitudinal lead screw, a machine plate fixed between the support plates, and a transverse lead screw drive installed between the machine plates. The machining assembly cooperates with the machine plate via the transverse lead screw drive.

[0006] The present invention is further configured such that a clamping assembly is installed at the end of the machine cover, the clamping assembly including a horizontal plate fixed to the upper side of the end of the machine cover, a gas rod installed in the middle of the horizontal plate, and a pressure plate connected to the telescopic end of the gas rod.

[0007] The present invention is further configured such that the pressure plate is located between the lower side of the horizontal plate and the upper part of the hollow panel, and a guide rod is fixed at the end of the pressure plate, the guide rod passing through the end of the horizontal plate.

[0008] The present invention is further configured such that the collection chamber is a conical structure, and the bottom of the collection chamber is detachably equipped with a discharge cover.

[0009] The present invention is further configured such that the processing assembly includes a mounting bracket that movably engages with the machine plate, and a processing head that uses a vertical lead screw structure to move and engage with the mounting bracket for lifting.

[0010] The present invention is further configured such that the mounting bracket cooperates with the transverse lead screw drive, and the bottom of the mounting bracket is arranged parallel to the hollow panel.

[0011] The present invention is further configured such that a movable groove is provided inside the machine cover, the bottom of the support plate is located in the movable groove, and moves linearly along the length direction of the movable groove.

[0012] This utility model has the following beneficial effects: 1. This utility model achieves precise positioning of the motor shaft in multiple degrees of freedom (lateral, longitudinal, and vertical) during machining by setting up a position adjustment component and a machining component in coordination, which greatly improves machining accuracy and automation and meets the machining requirements of high-precision parts.

[0013] 2. The clamping assembly of this utility model adopts a pneumatic rod drive to drive the pressure plate downward, and combined with the guide rod structure, it ensures the stable clamping of the workpiece during the processing, effectively preventing displacement caused by vibration or cutting force, and improving processing safety and finished product qualification rate.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1-4 This utility model is a CNC milling machine for producing and processing motor shafts, including a frame 100, a position adjustment component 200 disposed on the upper part of the frame 100, and a processing component 400 adapted to the position adjustment component 200. The frame 100 includes a machine frame 101, a hollow panel 102 laid flat inside the machine frame 101, and a collection bin 103 disposed below the hollow panel 102. The position adjustment component 200 includes a machine cover 201 fixed to the upper side edge of the machine frame 101, a support plate 203 installed inside the machine cover 201 by a longitudinal lead screw drive 202, a machine plate 204 fixed between the support plates 203, and a transverse lead screw drive 205 installed between the machine plates 204. The processing component 400 cooperates with the machine plate 204 by the transverse lead screw drive 205.

[0020] Specifically, a clamping assembly 300 is installed at the end of the machine cover 201. The clamping assembly 300 includes a horizontal plate 301 fixed to the upper side of the end of the machine cover 201, a pneumatic rod 302 installed in the middle of the horizontal plate 301, and a pressure plate 303 connected to the telescopic end of the pneumatic rod 302. The pressure plate 303 is located between the lower side of the horizontal plate 301 and the upper part of the hollow panel 102, and a guide rod 304 is fixed to the end of the pressure plate 303. The guide rod 304 passes through the end of the horizontal plate 301. The clamping assembly 300 is used to assist in the clamping and positioning of the motor shaft. In use, the pneumatic rod 302 drives the pressure plate 303 to clamp the motor shaft, and the guide rod 304 is used to balance the stable lifting and lowering of the pressure plate 303.

[0021] Furthermore, the processing assembly 400 includes a mounting bracket 403 that is movably coupled to the machine plate 204, and a processing head 402 that is vertically coupled to the mounting bracket 403 via a vertical lead screw structure 401. The mounting bracket 403 is coupled to a horizontal lead screw drive 205, and the bottom of the mounting bracket 403 is arranged parallel to the hollow panel 102. The vertical lead screw structure 401 in the processing assembly 400 is used to drive the vertical movement of the mounting bracket 403, thereby enabling the processing head 402 to process the motor shaft.

[0022] In addition, the collection bin 103 is a conical structure, and the bottom of the collection bin 103 is detachably equipped with a discharge cover 104 to facilitate the collection and cleaning of debris during the processing; the machine cover 201 is provided with a movable groove inside, the bottom of the support plate 203 is located in the movable groove, and moves linearly along the length of the movable groove. The machine cover 201 is used to limit the movement of the support plate 203, and also to protect the internal screw structure.

[0023] When using the CNC milling machine for manufacturing motor shafts according to this invention, the motor shaft to be processed must first be prepared, and the equipment must be in normal working condition. Before starting processing, the motor shaft is placed on the perforated panel 102 and fixed by the clamping assembly 300 installed at the end of the machine cover 201. Specifically, the pressure plate 303 is driven downward by the pneumatic rod 302 to firmly press the motor shaft, while the guide rod 304 ensures the stability and smoothness of the pressure plate 303's movement. Next, the position is adjusted according to the processing requirements. The longitudinal lead screw drive 202 and the transverse lead screw drive 205 in component 200 adjust the positions of the support plate 203 and the machine plate 204, thereby precisely setting the working starting point of the machining component 400 relative to the motor shaft. After positioning, the machining component 400 is started, and its mounting bracket 403 moves to the designated position along the transverse lead screw drive 205. Then, the vertical lead screw structure 401 controls the machining head 402 to descend to the surface of the motor shaft to begin machining. Waste generated during machining will fall into the conical collection chamber 103 through the perforated panel 102 for easy subsequent cleaning. After machining is completed, the machining head 402 is raised, the clamping component 300 is released, the machined motor shaft is taken out, and the machining quality is checked.
