Description

Technical Field

[0001] This utility model relates to the field of vertical spinning machine technology, and specifically to a stable clamping mechanism for a vertical spinning machine. Background Technology

[0002] This is a type of metal forming machinery. An AC servo system is installed on its bed. The system's rotating carriage has two mutually perpendicular carriages, one longitudinal and one transverse. The transverse and longitudinal feeds utilize precision ball screw pairs, which are connected in sequence by a servo motor to a synchronous belt drive pair and a precision ball screw pair. Precision ball linear guides are located below the carriages. A "copying" mechanism for the mandrel's outline is located above the transverse slide of the rotating carriage. The CNC system controlling the servo system and the programmable logic controller (PLC) controlling the hydraulic transmission system are both connected to an industrial PC.

[0003] Currently, a Chinese patent discloses a spinning wheel device for a spinning machine (authorization announcement number CN212494772U). The adjustable guide rail can drive the spinning wheel to make precise and convenient adjustments, and the adjustment is accurate. The setting of a clamping plate and a clamping groove can make the connection between the slider and the adjustable guide rail more stable and the movement smoother. The rotary motor can drive the workpiece to be processed to rotate, making the pressing smoother. The setting of a clamping plate and a telescopic motor can clamp and fix the workpiece to be processed, making the connection more stable.

[0004] According to the above reference materials, in the above device, the part is placed on the top of the top column, and the drive of the telescopic motor pushes the clamping plate downward. The clamping plate and the top column firmly clamp the part in the spinning machine. However, when the device is used to clamp and process the workpiece, the vertical spinning machine relies solely on the top column and the clamping plate to fix and stabilize the upper and lower ends of the workpiece. When the machine is rotating, it is easy for the workpiece to shift during processing, which is not convenient for the vertical spinning machine to be clamped stably, thus reducing the effectiveness of the device.

[0005] Based on this, this utility model designs a stable clamping mechanism for a vertical spinning machine to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stable clamping mechanism for a vertical spinning machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A stabilizing clamping mechanism for a vertical spinning machine includes a spinning machine body, a worktable rotatably connected to the inner bottom wall of the spinning machine body, and a clamp installed on the inner top wall of the spinning machine body. The mechanism is characterized by further including a limiting mechanism disposed on the inner wall of the spinning machine body. Mounting brackets are slidably connected to both sides of the inner wall of the spinning machine body. A mounting plate is fixedly connected to one side of the inner wall of each mounting bracket, and a fixing plate is slidably connected to one side of the inner wall of each mounting plate. A plurality of evenly distributed ball bearings are rotatably connected to the inner wall of the fixing plate. A fixing assembly is provided on the inner wall of the spinning machine body.

[0009] Furthermore, the limiting mechanism also includes an electric push rod mounted on the top of one side of the mounting frame, one end of which passes through the mounting frame and the mounting plate in sequence and is fixedly connected to the fixing plate.

[0010] Furthermore, two guide rods are slidably connected to both sides of the mounting plate, with one end of each guide rod penetrating the mounting plate and being fixedly connected to both sides of the fixing plate.

[0011] Furthermore, limit plates are fixedly connected to both the top of the workbench and the bottom of the fixture.

[0012] Furthermore, a limiting groove is provided at one end of the limiting plate.

[0013] Furthermore, the fixing component includes sliders fixedly connected to both sides of the bottom of the spinning machine body, and the sliders are slidably connected to the inner wall of the spinning machine body.

[0014] Furthermore, a bidirectional lead screw is rotatably connected to one side of the inner wall of the spinning machine body, and the two ends of the bidirectional lead screw are respectively threaded to two of the sliders.

[0015] Furthermore, protective sleeves are fixedly connected to both sides of the slider, and the protective sleeves are disposed on the outer wall of the bidirectional lead screw. Beneficial effects

[0016] 1. The spinning machine body can clamp and fix the bottom of the workpiece by moving to one side through the mounting plates on both sides of its inner wall and the fixing plate on its inner wall. The fixing plate is higher than the bottom of the worktable, which facilitates the limiting clamping of the workpiece. The ball bearings in the fixing plate guide the workpiece when the mounting plate and the fixing plate clamp it. When the spinning machine body drives the workpiece to rotate, the fixing plate and the ball bearings cooperate to clamp the workpiece without affecting the rotation of the workpiece. The two guide rods can position and support the fixing plate. The limiting plate and limiting groove on the worktable and the fixture can improve the clamping effect of the workpiece and can stably clamp the workpiece, thus improving the clamping effect of the spinning machine.

[0017] 2. When clamping and fixing the workpiece, the mounting bracket slides on the spinning machine body via the bottom slider, which can adjust the position of the mounting plate and the fixing plate. The two sliders cooperate with the two ends of the double-acting screw to move simultaneously from one side to the middle to clamp and fix the workpiece. The protective sleeve can protect the double-acting screw and reduce the influence of external dust and impurities on the double-acting screw, which can stably clamp the workpiece and improve the use effect of the device.

[0025] 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. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A stabilizing clamping mechanism for a vertical spinning machine includes a spinning machine body 1, a worktable 2 rotatably connected to the inner bottom wall of the spinning machine body 1, a clamp 3 installed on the inner top wall of the spinning machine body 1, and a limiting mechanism 4 disposed on the inner wall of the spinning machine body 1. Mounting brackets 401 are slidably connected to both sides of the inner wall of the spinning machine body 1. A mounting plate 402 is fixedly connected to one side of the inner wall of the mounting bracket 401. A fixing plate 403 is slidably connected to one side of the inner wall of the mounting plate 402. A plurality of evenly distributed ball bearings 404 are rotatably connected to the inner wall of the fixing plate 403. A fixing component 409 is provided on the inner wall of the spinning machine body 1.

[0028] The workpiece is placed on the worktable 2. Manually rotating the two-way lead screw 4092, which is threadedly connected to the two mounting brackets 401, can move the mounting plate 402 and the fixing plate 403 to one side to clamp the spinning machine body 1. When controlled by the PLC system, the clamp 3 moves downward to cooperate with the worktable 2 to clamp the workpiece. The worktable 2 drives the workpiece to rotate through the motor inside the spinning machine body 1. The fixing plate 403 guides the workpiece through the ball bearings 404. The spinning wheels on both sides of the inner wall of the spinning machine body 1 rotate and process the workpiece into shape. The workpiece can be stably clamped during processing.

[0029] In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the limiting mechanism 4 further includes an electric push rod 405 mounted on the top of one side of the mounting frame 401. One end of the electric push rod 405 passes through the mounting frame 401 and the mounting plate 402 in sequence and is fixedly connected to the fixing plate 403.

[0030] When clamping and fixing the workpiece, the PLC control system can drive one end of the electric push rod 405 to move the fixing plate 403 and the ball bearing 404 to one side to clamp the workpiece, thereby improving the clamping effect of the spinning machine.

[0031] In this embodiment of the utility model, two guide rods 406 are slidably connected to both sides of the mounting plate 402. One end of the guide rod 406 passes through the mounting plate 402 and is fixedly connected to both sides of the fixing plate 403.

[0032] When the fixed plate 403 moves to one side, the two guide rods 406 can move along with it to provide positioning support for the fixed plate 403.

[0033] In this embodiment of the utility model, the top of the workbench 2 and the bottom of the clamp 3 are both fixedly connected to a limiting plate 407.

[0034] When the fixture 3 moves downward to fix the workpiece on the worktable 2, the limiting plate 407 between the fixture 3 and the inner wall of the worktable 2 can improve the clamping effect of the fixture 3 on the workpiece and prevent it from shifting during processing.

[0035] In this embodiment of the utility model, a limiting groove 408 is provided at one end of the limiting plate 407.

[0036] The limiting groove 408 on the limiting plate 407 can improve the clamping stability of the workpiece between the fixture 3 and the worktable 2.

[0037] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the fixing component 409 includes sliders 4091 fixedly connected to both sides of the bottom of the spinning machine body 1, and the sliders 4091 are slidably connected to the inner wall of the spinning machine body 1.

[0038] The mounting bracket 401 moves to one side along the groove on the spinning machine body 1 via the bottom slider 4091, which can drive the mounting plate 402 and the fixing plate 403 to clamp the workpiece, thereby improving the effectiveness of the device.

[0039] In this embodiment of the present invention, a bidirectional lead screw 4092 is rotatably connected to one side of the inner wall of the spinning machine body 1, and the two ends of the bidirectional lead screw 4092 are respectively threadedly connected to two sliders 4091.

[0040] Manually rotating the bidirectional lead screw 4092 causes the two ends of the bidirectional lead screw 4092 to be threadedly connected to two sliders 4091, which in turn drive the two mounting brackets 401 to move simultaneously from one side to the middle to clamp the workpiece, thereby improving the clamping stability of the device.

[0041] In this embodiment of the utility model, protective sleeves 4093 are fixedly connected to both sides of the slider 4091, and the protective sleeves 4093 are disposed on the outer wall of the bidirectional lead screw 4092.

[0042] When the bidirectional lead screw 4092 moves the mounting bracket 401 to one side, it will squeeze one of the protective sleeves 4093, and the other protective sleeve 4093 will extend accordingly. The two protective sleeves 4093 can protect the bidirectional lead screw 4092.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
