Description

Technical Field

[0001] This utility model belongs to the field of rotating shaft processing technology, specifically relating to an automatic milling fixture for rotating shafts. Background Technology

[0002] An automatic milling fixture for shafts is a specialized clamping device used in machining to automatically mill keyways on shaft-type parts. It ensures machining accuracy and efficiency through automated positioning and clamping mechanisms, and is typically integrated into a milling machine or machining center. These fixtures may employ multi-point positioning (such as a combination of axial and radial clamps) to enhance stability, or be designed with special transmission structures (such as gear-driven "drive arms") to achieve complex groove machining.

[0003] According to CN202121112162.6, an automatic milling fixture for a rotating shaft includes a transverse slide table, a longitudinal slider slidingly fitted on the transverse slide table, and a clamping block fixed on the longitudinal slider. The clamping block has clamping holes penetrating both sides of the clamping block, and each clamping hole has a transverse notch extending to the end face of the clamping block. A bolt is mounted on the top of the clamping block, threaded downwards and connecting to the clamping block, penetrating the transverse notch. The rotating shaft is placed in the clamping holes, and the diameter of the clamping holes is adjusted by rotating the bolts. One end of the longitudinal slider is connected to a hydraulic cylinder, and the piston rod of the hydraulic cylinder drives the longitudinal slider to move longitudinally for milling operations. This automatic milling fixture for a rotating shaft uses a hydraulic cylinder and slide table feed structure, and utilizes the deformation of the clamping block under force to clamp the rotating shaft. It has a simple structure and strong applicability.

[0004] The aforementioned automatic milling fixture for shafts still has some defects, including insufficient positioning stability: the shaft is fixed by only a single fixture, which easily causes vibration during processing and affects the accuracy of the groove position; low degree of automation: the workpiece position needs to be adjusted frequently by hand, resulting in low efficiency; and lack of anti-pinch design. Therefore, we propose an automatic milling fixture for shafts. Utility Model Content

[0005] The purpose of this invention is to provide an automatic milling fixture for a rotating shaft to solve the problems of insufficient positioning stability and low degree of automation mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic milling fixture for a rotating shaft, comprising a worktable, a first slide groove on the top of the worktable, a first slider inside the first slide groove, the first slider being movably connected inside the first slide groove, a movable rod fixedly connected to the top of the first slider, a second slide groove on the top of the movable rod, a second slider inside the second slide groove, the second slider being movably connected inside the second slide groove, a snap-fit ​​bracket fixedly connected to the top of the second slider, a fixing bracket fixedly connected to the front and rear sides and the left and right sides of the snap-fit ​​bracket, an electric push rod fixedly connected inside the fixing bracket, the electric push rod extending into the snap-fit ​​bracket, an arc-shaped clamp fixedly connected to the output end of the electric push rod on the front and rear sides, and a limiting clamp fixedly connected to the output end of the electric push rod on the left and right sides.

[0007] Preferably, each of the first slide groove and the second slide groove is provided with a threaded rod, which is rotatably connected inside the first slide groove and the second slide groove, respectively. The first slider and the second slider are both connected to the threaded rod by threads. One end of the threaded rod is provided with a motor, which is fixedly connected to the outside of the worktable and the outside of the movable rod, respectively.

[0010] Preferably, the bottom of the workbench is fixedly connected with anti-slip legs, and four anti-slip legs are provided and fixedly connected to the bottom corners of the workbench.

[0011] Preferably, a support rod is fixedly connected to the top corner of the workbench, and a control panel is fixedly connected to the top of the support rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By clamping the front and rear sides of the rotating shaft with two arc-shaped clamping plates and clamping the left and right sides of the rotating shaft with limiting plates, multiple sets of fixtures fix the rotating shaft, avoiding vibration during processing and preventing it from affecting the accuracy of the slot. The drive device inside the first and second slides is activated by the control terminal, which drives the movable rod to move left and right and the clamping frame to move back and forth, thereby realizing the position adjustment of the rotating shaft. This facilitates automated position adjustment, eliminating the need for frequent manual adjustment of the workpiece position and resulting in high efficiency.

[0013] 2. By starting the motor through the control terminal, the threaded rod can be driven to move automatically inside the first slide groove, and the second slide can move automatically inside the second slide groove. This facilitates the automatic position adjustment of the fixed rotating shaft. The control panel makes it easy to control the start and stop of the motor and electric push rod, and facilitates the overall automated operation of the device. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0017] Please see Figure 1-3This utility model provides an automatic milling fixture for a rotating shaft: It includes a worktable 1, a first slide groove 2 on the top of the worktable 1, a first slider 3 inside the first slide groove 2, the first slider 3 being movably connected inside the first slide groove 2, a movable rod 4 fixedly connected to the top of the first slider 3, a second slide groove 5 on the top of the movable rod 4, a second slider 6 inside the second slide groove 5, the second slider 6 being movably connected inside the second slide groove 5, a locking frame 7 fixedly connected to the top of the second slider 6, a fixing frame 8 fixedly connected to the front and rear sides and the left and right sides of the locking frame 7, an electric push rod 9 fixedly connected inside the fixing frame 8, the electric push rod 9 extending into the locking frame 7, an arc-shaped clamping plate 10 fixedly connected to the output end of the electric push rod 9 on the front and rear sides, and a limiting clamping plate 11 fixedly connected to the output end of the electric push rod 9 on the left and right sides. The rotating shaft is placed inside the clamping frame 7, positioned between two arc-shaped clamping plates 10 and a limiting clamping plate 11. After placement, four electric push rods 9 are simultaneously activated via the control terminal, causing the two arc-shaped clamping plates 10 to clamp the front and rear sides of the rotating shaft, and the limiting clamping plate 11 to clamp the left and right sides of the rotating shaft. After clamping, milling is performed to improve positioning stability. Multiple sets of fixtures fix the rotating shaft to prevent vibration during processing and avoid affecting the accuracy of the groove. The drive devices inside slide 1 2 and slide 2 5 are activated via the control terminal, causing slide 1 3 to move inside slide 1 2 and slide 2 6 to move inside slide 2 5, driving the movable rod 4 to move left and right and the clamping frame 7 to move back and forth, thereby realizing the position adjustment of the rotating shaft. This facilitates automated position adjustment, eliminating the need for frequent manual adjustments to the workpiece position and resulting in high efficiency.

[0018] Specifically, each of the first slide 2 and the second slide 5 is equipped with a threaded rod 12. The threaded rod 12 is rotatably connected inside the first slide 2 and the second slide 5, respectively. The first slider 3 and the second slider 6 are both threadedly connected to the threaded rod 12. One end of the threaded rod 12 is equipped with a motor 13. The motor 13 is fixedly connected to the outside of the worktable 1 and the outside of the movable rod 4, respectively. By starting the motor 13 through the control terminal, the threaded rod 12 is driven to rotate, which allows the first slider 3 to move automatically inside the first slide 2 and the second slider 6 to move automatically inside the second slide 5, which brings convenience to the automatic position adjustment of the fixed rotating shaft.

[0019] Specifically, the inner side of the arc-shaped clamping plate 10 is provided with anti-slip protrusions, and there are multiple anti-slip protrusions. The protective protrusions inside the arc-shaped clamping plate 10 improve the stability after clamping the front and rear sides of the rotating shaft.

[0020] Specifically, the limiting plate 11 has a limiting groove 14 inside, and the limiting groove 14 has anti-slip texture inside. The limiting groove 14 and the anti-slip texture improve the stability after clamping the left and right sides of the rotating shaft.

[0021] Specifically, the bottom of the workbench 1 is fixedly connected with anti-slip legs 15. There are four anti-slip legs 15, which are fixedly connected to the bottom corners of the workbench 1. The anti-slip legs 15 improve the anti-slip effect of the workbench 1 during use and prevent displacement during use.

[0022] Specifically, a support rod 16 is fixedly connected to the top corner of the workbench 1, and a control panel 17 is fixedly connected to the top of the support rod 16. The control panel 17 facilitates the start and stop of the motor 13 and the electric push rod 9, bringing convenience to the overall automated operation of the device tooling.

[0023] In this implementation scheme, when using the tooling, the rotating shaft is placed inside the clamping frame 7, positioned between the two arc-shaped clamping plates 10 and the limiting clamping plate 11. After placement, the four electric push rods 9 are simultaneously activated via the control terminal, causing the two arc-shaped clamping plates 10 to clamp the front and rear sides of the rotating shaft, and the limiting clamping plate 11 to clamp the left and right sides of the rotating shaft. After clamping, milling operations are performed, improving positioning stability. The debris generated during milling is left inside the clamping frame 7 for easy cleaning later. Multiple sets of fixtures fix the rotating shaft, preventing vibration during processing and avoiding affecting the groove accuracy. The drive devices inside the first slide 2 and the second slide 5 are activated via the control terminal, causing the first slider 3 to move inside the first slide 2 and the second slider 6 to move inside the second slide 5, driving the movable rod 4 to move left and right and the clamping frame 7 to move back and forth, thereby achieving position adjustment of the rotating shaft. This facilitates automated position adjustment, eliminating the need for frequent manual adjustments to the workpiece position and resulting in high efficiency.
