Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a cutting device for machining a generator casing. Background Art

[0002] A cutting device is a mechanical device or tool combination used to cut materials. It usually includes cutting tools, fixtures, transmission mechanisms, control systems and other parts.

[0004] The above-mentioned cutting device still has some shortcomings in actual use:

[0005] When the cutting device is limiting and fixing the casing, the two hydraulic cylinders respectively drive the positioning bracket and the clamping plate in turn to clamp and fix the casing. The two cylinders need to be operated step by step during fixing, which not only increases the cost of the equipment, but also makes the operation more complicated. The step-by-step operation will seriously affect the efficiency of casing processing. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that two oil cylinders are operated step by step, which not only increases the cost of the equipment, but also makes the operation more complicated. The step-by-step operation will seriously affect the efficiency of casing processing, and a cutting device for generator casing processing is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A cutting device for machining a generator casing comprises a workbench, a table top is fixedly connected to the top of the workbench, a machining table is fixedly connected to the top of the table top, two clamping plates are arranged on the top of the machining table, the two clamping plates are close to each other and can clamp the two sides of the casing; a top cover is also included, and the top cover is located above the machining table, when the top cover moves downward, the top of the casing can be pressed, the top of the top cover is fixedly connected to a loading plate, and the cooperation between the top cover and the loading plate can limit the casing.

[0009] In one possible design, a bidirectional screw is rotatably connected in the processing table, nuts are threadedly sleeved on the positive and negative threaded sections of the bidirectional screw, and the nuts are slidably connected in the processing table, a connecting block is fixedly connected to the top of the nut, and the top of the connecting block is fixedly connected to the clamping plate, a driving motor is fixedly connected to the top of the table, and the output shaft of the driving motor extends into the processing table and is fixedly connected to one end of the bidirectional screw.

[0010] In one possible design, a support shaft is rotatably connected inside the processing table, a fixed sleeve is fixedly connected to the top of the processing table, and the support shaft extends to the top of the processing table and rotatably passes through the fixed sleeve, a threaded section is provided on the outer wall of the support shaft, and a top cover threaded sleeve is provided on the threaded section of the support shaft.

[0011] In a possible design, a rotating shaft is rotatably connected inside the processing table, the outer wall fixed sleeve of the rotating shaft is provided with a second gear, the outer wall fixed sleeve of the bidirectional screw is provided with a first gear, and the second gear and the first gear are meshed, thereby driving the rotating shaft to rotate, the outer wall fixed sleeve of the rotating shaft is provided with a second bevel gear, the outer wall fixed sleeve of the supporting shaft is provided with a first bevel gear, and the first bevel gear and the second bevel gear are meshed, thereby driving the supporting shaft to rotate.

[0012] In a possible design, the bottom of the top cover is fixedly connected to a limiting rod, and the limiting rod slides through the fixing sleeve, and the lifting and lowering of the top cover can be limited by the limiting rod.

[0013] In a possible design, a cutting body is provided on one side of the processing table, and the cutting body is fixedly connected to the table top. A control box is fixedly installed on one side of the cutting body, and the driving motor and the cutting body are electrically connected to the control box respectively. The control box can control the cutting body and the driving motor respectively.

[0014] In this application, the device mainly includes a workbench and a cutting body, and a power structure is provided on the rear side of the cutting body. On the top of the workbench, we fixedly connected a table top, which provides a stable support base for the cutting device. On the top of the table top, we fixedly connected a processing table. This platform is the main working area for the cutting operation. On the top of the processing table, there are two clamping plates. These two clamping plates can be close to each other to clamp and fix the two sides of the generator casing to ensure the stability and positioning accuracy of the casing during the cutting process. In addition, we have also designed a top cover, which is located above the processing table. When the top cover moves downward, it can press the top of the casing, and together with the clamping plate, it can achieve all-round limiting of the casing. Next, let's look at the driving mechanism of the clamping plate and the top cover. In the processing table, we rotatably connected a bidirectional screw. The forward and reverse threaded sections of this bidirectional lead screw are both threaded with nuts, which can slide along the axis of the threaded rod when the bidirectional lead screw rotates. The top of the nut is fixedly connected to a connecting block, and the top of these connecting blocks is fixedly connected to the clamping plate. Therefore, when the bidirectional lead screw rotates, it drives the two clamping plates to move closer or farther away from each other, thereby clamping and releasing the casing. In order to drive the bidirectional lead screw, we fixedly connect a drive motor to the top of the table. The output shaft of the drive motor extends into the processing table and is fixedly connected to one end of the bidirectional lead screw. In this way, by controlling the forward and reverse rotation of the motor, we can realize the clamping and releasing operations of the clamping plate. For the top cover, we also rotatably connect a support shaft in the processing table. The outer wall of this support shaft is provided with a threaded section, and the top cover is threadedly sleeved on this threaded section. Therefore, when the support shaft rotates, it will drive the top cover to rise and fall along its axis, thereby realizing the pressing and releasing of the top of the casing. In order to link the bidirectional screw and the support shaft, we fixedly sleeved a first gear on the outer wall of the bidirectional screw, and rotatably connected a rotating shaft in the processing table. The outer wall of the rotating shaft is also fixedly sleeved with a second gear, which is meshed with the first gear. Therefore, when the bidirectional screw rotates, it will drive the rotating shaft to rotate through the first gear and the second gear. The outer wall of the rotating shaft is also fixedly sleeved with another second bevel gear, which is meshed with the first bevel gear fixedly sleeved on the outer wall of the support shaft. In this way, the rotation of the rotating shaft will drive the rotation of the supporting shaft, thereby realizing the linkage between the clamping plate and the top cover. In order to increase the stability of the top cover lifting, we fixed a limit rod at its bottom, and this limit rod slides through the top of the fixed sleeve. When the support shaft rotates to adjust the lifting of the top cover, the limit rod will play a guiding and limiting role. Finally, a control box is set on one side of the cutting body, and the control box is electrically connected to the drive motor and the cutting body respectively. Through the control box, we can easily control the drive motor and the cutting body, thereby realizing the operation and control of the entire cutting device.

[0015] Beneficial effects:

[0016] In the utility model, the cutting device for machining the generator casing can realize fast clamping of both sides of the generator casing by designing two clamping device clamping plates, thereby ensuring the stability of the casing during machining. At the same time, the top cover of the top pressing device cooperates with the clamping device clamping plates to achieve all-round positioning of the casing, thereby ensuring machining accuracy.

[0017] In the utility model, the cutting device for machining the generator casing adopts a linkage drive system composed of a first gear, a second gear, a first bevel gear and a second bevel gear, so that the bidirectional threaded rod, the bidirectional screw rod and the driving threaded rod support shaft can rotate synchronously, thereby realizing the linkage between the clamping plate of the clamping device and the top cover of the pressing device. This design simplifies the operation process and improves work efficiency;

[0018] The utility model is suitable for processing generator casings of different sizes and shapes. By adjusting the position and parameters of the clamping plate of the clamping device and the top cover of the pressing device, different processing requirements can be met. In addition, the cutting device shows significant beneficial effects in clamping and positioning, ease of operation, stability and durability, wide applicability and flexibility.
