Description

Technical Field

[0001] This utility model relates to the field of machining technology, and more specifically, to a support frame structure for rotary machining workpieces. Background Technology

[0002] In machining and manufacturing, workpieces often need to undergo machining processes such as drilling, cutting, and milling. Therefore, a support frame is needed as a support platform for placing the workpiece and supporting it. In addition, the support frame also needs to be equipped with suitable fixtures to clamp and stabilize the workpiece in order to carry out the above machining processes and meet production needs.

[0003] Existing support frames generally have simple functions, typically only providing support and clamping for the workpiece. They cannot meet more advanced needs. Furthermore, they often use specific clamping on both sides of the workpiece, and some special processes require rotation of the workpiece, which causes the support surface to tilt. This can cause the workpiece to tend to slide downwards along the tilted clamping surface. In addition, the mechanical vibration generated during processing can easily cause the workpiece to slide and change displacement, which can affect the processing accuracy.

[0004] In summary, to meet the demand for more comprehensive functions in rotary machining scenarios, and to ensure the stability of workpiece rotation operations under special processes and to guarantee that machining accuracy is not affected, it is necessary to address the problems of existing support frames that are limited to support and clamping, the tendency of workpieces to slide down due to the tilting of the support surface caused by workpiece rotation in special processes, and the exacerbation of workpiece displacement by machining vibration. The goal is to enable rotary machining workpiece support frames to have richer functions to adapt to diverse machining needs, and to effectively suppress the risk of workpiece slide-down when the support surface is tilted and the displacement problems caused by mechanical vibration, thus ensuring workpiece machining accuracy. Utility Model Content

[0005] The rotary machining workpiece support frame structure provided by this utility model aims to solve the following problems: existing support frames have only one function, which can only achieve support and clamping; in special processes, the rotation of the workpiece causes the support surface to tilt, resulting in the workpiece sliding tendency; and the vibration of the machining machinery aggravates the workpiece displacement.

The output end of the vertical rotation motor is fixedly connected to the rotating shaft of the rotating cylinder. The machine is used to drive the rotating drum to rotate, and the horizontal rotating motor is used to drive the support plate to rotate. The clamping mechanism includes a side clamping module installed on the connecting frame and a top pressing module one on the output end of the connecting frame. The side clamping module is used to clamp and fix the side of the workpiece, and the top pressing module one is used to press and fix the top of the workpiece. The anti-slip stabilizing mechanism includes an orientation adjustment module installed at the bottom of the placement plate, a side abutment adjustment module installed at the output end of the orientation adjustment module, and a top pressing module two installed at the output end of the side abutment adjustment module. The orientation adjustment module is used to adjust the orientation of the side abutment adjustment module, the side abutment adjustment module is used to abut the workpiece and adjust the position of the top pressing module two, and the top pressing module two is used to press and fix the top of the workpiece.

[0007] In a preferred embodiment, the side clamping module includes a cylinder embedded and fixedly connected to a connecting frame and an L-shaped push frame fixedly connected to the output end of the cylinder. The cylinder is used to push the L-shaped push frame to move.

[0008] In a preferred embodiment, the top pressing module 1 includes a threaded rod threaded through and connected to an L-shaped pusher frame 1, a knob fixedly connected to one end of the threaded rod, and a pressure plate 1 rotatably connected to the other end of the threaded rod.

[0009] In a preferred embodiment, the orientation adjustment module includes an orientation adjustment motor fixedly connected to the bottom of the placement plate and a tray fixedly connected to the output end of the orientation adjustment motor, wherein the orientation adjustment motor is used to drive the tray to rotate.

[0010] In a preferred embodiment, the side contact adjustment module includes a cylinder two fixedly connected to the support plate and an L-shaped push frame two fixedly connected to the output end of the cylinder two. The cylinder two is used to drive the L-shaped push frame two to move.

[0011] In a preferred embodiment, the top pressing module 2 includes a cylinder 3 embedded and fixedly connected to the L-shaped push frame 2 and a pressure plate 2 fixedly connected to the output end, wherein the cylinder 3 is used to drive the pressure plate 2 to move.

[0012] In a preferred embodiment, the support plate, connecting frame, connecting plate and placement plate are an integrated structure, and the inner side of the connecting frame is provided with a groove for the L-shaped push frame two and cylinder three to pass through.

[0013] In a preferred embodiment, a mounting bracket is fixedly connected to the tray, an arc-shaped sliding plate is fixedly connected to the mounting bracket, a slide rail is fixedly connected to the bottom of the tray, and the arc-shaped sliding plate is slidably disposed within the slide rail.

[0014] In a preferred embodiment, an arc-shaped limiting block is fixedly connected to the arc-shaped sliding plate, and a matching annular limiting groove is provided on the inner side of the slide rail, with the arc-shaped limiting block slidably disposed in the annular limiting groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model, by setting up a rotation drive structure in both vertical and horizontal directions, combined with an integrated clamping mechanism that includes side clamping and top pressing, can not only realize the adjustment of the tilt angle of the workpiece in the vertical direction and the 360° switching of the workpiece in the horizontal direction, but also form a "side-top" dual-base fixation for the workpiece. It breaks through the limitation of the single function of traditional support frames, enriches the application scenarios, and meets the diverse needs of different processing technologies for workpiece posture and fixation methods.

[0017] This invention features a fully movable anti-slip stabilizing mechanism that can precisely move to the lowest point of the workpiece when it is tilted. First, the side abutment structure fits against the side of the workpiece, and then the top pressing structure applies fixing pressure to form a targeted secondary anti-fall fixation. This effectively counteracts the downward trend of the workpiece caused by processing vibration, prevents the workpiece from shifting due to sliding, and ensures the stability of processing accuracy.

[0018] This utility model provides precise guidance and reliable support for the rotational movement of the anti-slip stabilizing mechanism by setting an arc-shaped sliding plate and a sliding rail cooperation structure at the orientation adjustment structure, and combining it with an arc-shaped limiting block and an annular limiting groove limiting design. This not only reduces shaking during rotation and prevents parts from falling off, but also improves the rigidity and stability of the overall structure during processing, further ensuring the smooth operation of the various functional modules.

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Refer to the instruction manual appendix Figures 1 to 5The rotary machining workpiece support frame structure includes a chassis 1, a U-shaped support frame 2 fixedly connected to the chassis 1, a rotating cylinder 3 rotatably connected to the inner side of the U-shaped support frame 2 via a rotating shaft, a vertical rotation motor 4 fixedly connected to the outer side of the U-shaped support frame 2, a horizontal rotation motor 5 fixedly connected to the inner side of the rotating cylinder 3, a support plate 6 fixedly connected to the output end of the horizontal rotation motor 5, a support plate 9 fixedly connected to the support plate 6, two connecting frames 10 fixedly connected to the support plate 9, connecting plates 11 fixedly connected to the connecting frames 10, a placement plate 12 fixedly connected between the two connecting plates 11, a clamping mechanism mounted on the connecting frames 10, and an anti-slip stabilizing mechanism mounted on the placement plate 12. The output end of the vertical rotation motor 4 is fixedly connected to the rotating shaft of the rotating cylinder 3. 4 is used to drive the rotating cylinder 3 to rotate, and the horizontal rotating motor 5 is used to drive the support plate 6 to rotate. The clamping mechanism includes a side clamping module installed on the connecting frame 10 and a top pressing module one on the output end of the connecting frame 10. The side clamping module is used to clamp and fix the side of the workpiece, and the top pressing module one is used to press and fix the top of the workpiece. The anti-slip stabilizing mechanism includes an orientation adjustment module installed at the bottom of the placement plate 12, a side abutment adjustment module installed on the output end of the orientation adjustment module, and a top pressing module two installed on the output end of the side abutment adjustment module. The orientation adjustment module is used to adjust the orientation of the side abutment adjustment module, the side abutment adjustment module is used to abut the workpiece and adjust the position of the top pressing module two, and the top pressing module two is used to press and fix the top of the workpiece.

[0027] It should be noted that the vertical rotation motor 4 drives the rotating cylinder 3 to rotate around the axis of the U-shaped support frame 2, which can adjust the tilt angle of the workpiece in the vertical direction and adapt to processing scenarios that require angle adjustment; the horizontal rotation motor 5 drives the support plate 9, the placement plate 12 and other components to rotate through the support plate 6, which can realize the horizontal 360° rotation of the workpiece and meet the needs of multi-station processing. The combination of the two enriches the function of the support frame. The side clamping module of the clamping mechanism is fixed from the side of the workpiece, and the top pressing module 1 applies pressure from the top to form a basic "side-top" fixation; the orientation adjustment module of the anti-slip stabilizing mechanism can drive the side abutment adjustment module and the top pressing module 2 to rotate, and the side abutment adjustment module can extend and retract through the groove of the connecting frame 10 to achieve 360° movement. When the workpiece is tilted, the mechanism can accurately move to the lowest point of the workpiece, and form a secondary fixation through the side abutment and the top pressing, which effectively counteracts the downward trend of the workpiece caused by processing vibration and avoids displacement from affecting the processing accuracy.

[0028] Refer to the instruction manual appendix Figure 2 The side clamping module includes a cylinder 701 embedded and fixedly connected to the connecting frame 10 and an L-shaped push frame 702 fixedly connected to the output end of the cylinder 701. The cylinder 701 is used to push the L-shaped push frame 702 to move.

[0029] It should be noted that in the side clamping module, cylinder 701 is embedded and fixed on the connecting frame 10, which can reduce space occupation and avoid interference with surrounding components. When it is working, it pushes the L-shaped pusher 702 to move closer to and fit against the side of the workpiece to achieve side clamping of the workpiece. Wear-resistant pads can be added to the clamping surface of the L-shaped pusher 702, which can not only enhance the friction with the workpiece and improve the clamping stability, but also prevent hard contact from scratching the surface of the workpiece. At the same time, the clamping force can be adjusted according to the size of the workpiece to adapt to different specifications of shaft and disc sleeve workpieces, providing a stable foundation for the precise positioning of the top pressing module 1 in the subsequent process.

[0030] Refer to the instruction manual appendix Figure 2 The top pressing module includes a threaded rod 703 threaded through and connected to an L-shaped pusher frame 702, a knob 704 fixedly connected to one end of the threaded rod 703, and a pressure plate 705 rotatably connected to the other end of the threaded rod 703.

[0031] It should be noted that in the top pressing module one, the operator can rotate the knob 704 to drive the threaded rod 703 to move axially along the threaded hole of the L-shaped push frame one 702, thereby pushing the pressure plate one 705 closer to the top of the workpiece and applying pressure. Since the pressure plate one 705 and the threaded rod 703 are rotatably connected, it can ensure that the pressure plate one 705 always maintains surface contact with the top of the workpiece, avoiding local deformation of the workpiece caused by point contact. Moreover, the pressing pressure can be finely adjusted by the knob 704, which is suitable for fixing thin-walled workpieces. When used in conjunction with the side clamping module, it forms a 360-degree "up, down, left, and right" basic fixation of the workpiece, solving the problem of traditional support frames only clamping on one side and not being firmly fixed.

[0032] Refer to the instruction manual appendix Figure 4 and 5 The orientation adjustment module includes an orientation adjustment motor 801 fixedly connected to the bottom of the placement plate 12 and a tray 802 fixedly connected to the output end of the orientation adjustment motor 801. The orientation adjustment motor 801 is used to drive the tray 802 to rotate.

[0033] It should be noted that in the orientation adjustment module, when the orientation adjustment motor 801 is working, it drives the support plate 802 to rotate, which in turn drives the side contact adjustment module and the top pressing module installed on the support plate 802 to rotate synchronously. The orientation of these two modules can be adjusted according to the tilt angle and position of the workpiece to ensure that they can be accurately aligned with the key support points of the workpiece (especially the lowest point of the tilted workpiece). The structural design of the support plate 802 facilitates the installation and maintenance of the side contact adjustment module, provides a directional control basis for the anti-slip stabilizing mechanism to achieve accurate alignment, and ensures the accuracy of subsequent contact and pressing actions.

[0034] Another alternative embodiment based on the orientation adjustment module design: The new orientation adjustment module includes a stepper motor fixedly connected to the bottom of the placement tray 12, a planetary gear reducer fixed between the output end of the stepper motor and the tray 802, a high-precision angle encoder fixed to the side of the tray 802 and in contact with the bottom of the placement tray 12, and an electromagnetic braking unit fixed to the housing of the planetary gear reducer; the stepper motor provides rotational power, the planetary gear reducer amplifies the torque and reduces the speed, the high-precision angle encoder provides feedback on the rotation angle, and the electromagnetic braking unit locks after the tray 802 is in position. This embodiment solves the problems of insufficient torque and low positioning accuracy of the original module by adding a reducer, encoder and braking unit. The reducer can prevent the motor from "losing steps" and is suitable for heavy-load workpieces, the encoder improves the positioning accuracy, and the braking unit can avoid the offset of the tray 802 caused by processing vibration, making it more suitable for heavy workpiece processing.

[0035] Refer to the instruction manual appendix Figure 4 The side-mounted adjustment module includes a second cylinder 803 fixedly connected to the support plate 802 and an L-shaped push frame 804 fixedly connected to the output end of the second cylinder 803. The second cylinder 803 is used to drive the L-shaped push frame 804 to move.

[0036] It should be noted that in the side contact adjustment module, cylinder 2 803 drives L-shaped pusher 2 804 to move horizontally. When it is necessary to avoid the connecting frame 10, cylinder 2 803 drives L-shaped pusher 2 804 to retract and pass through the groove on the inner side of the connecting frame 10, and then extends according to the position of the workpiece, so that L-shaped pusher 2 804 fits against the side of the workpiece (especially the lowest point side of the inclined workpiece), realizing the side contact of the workpiece. This telescopic design can avoid the connecting frame 10 from blocking the movement of the module, realize 360° side contact without dead angles, and at the same time provide stable side support for the precise pressing of the top pressing module 2.

[0037] Refer to the instruction manual appendix Figure 4 The top pressing module 2 includes a cylinder 3 805 embedded and fixedly connected to an L-shaped push frame 2 804 and a pressure plate 2 806 fixedly connected to the output end. The cylinder 3 805 is used to drive the pressure plate 2 806 to move.

[0038] It should be noted that in the second top pressing module, after the side abutment adjustment module is in contact with the side of the workpiece, the third cylinder 805 drives the second pressure plate 806 to move towards the top of the workpiece and apply pressure, forming a double anti-fall fixation of "side abutment + top pressing". The lower surface of the second pressure plate 806 can be equipped with a high friction coefficient pad, which can significantly enhance the friction with the workpiece. Even if vibration occurs during processing, it can effectively suppress the tendency of the workpiece to slide down the inclined surface. Moreover, the third cylinder 805 has a fast response speed and can adjust the pressing pressure in time, ensuring the anti-slip effect while avoiding excessive pressing that could damage the workpiece.

[0039] Refer to the instruction manual appendix Figure 1 The support plate 9, connecting frame 10, connecting plate 11 and placement plate 12 are integrated structures. The inner side of the connecting frame 10 is provided with a groove for the L-shaped push frame 804 and cylinder 805 to pass through.

[0040] It should be noted that the support plate 9, connecting frame 10, connecting plate 11 and placement tray 12 adopt an integrated structure, which can reduce the assembly gap between components, improve the rigidity and stability of the overall structure, avoid component loosening or displacement caused by processing vibration, reduce load fluctuation when driven by horizontal rotation motor 5, and extend the service life of motor. The groove size opened on the inner side of the connecting frame 10 is adapted to the L-shaped push frame 804 and cylinder 805, ensuring that the side abutment adjustment module and the top pressing module 2 can pass smoothly during extension or rotation without jamming or interference, and provide the necessary space for the 360° movement of the anti-slip stabilizing mechanism.

[0041] Refer to the instruction manual appendix Figure 4 and Figure 5 A mounting bracket 13 is fixedly connected to the tray 802, and an arc-shaped sliding plate 14 is fixedly connected to the mounting bracket 13. A slide rail 15 is fixedly connected to the bottom of the placement tray 12, and the arc-shaped sliding plate 14 is slidably disposed in the slide rail 15.

[0042] It should be noted that the mounting bracket 13 is fixed on the pallet 802, and the arc-shaped sliding plate 14 is fixed on the mounting bracket 13 and slidably disposed in the slide rail 15 at the bottom of the placement tray 12. When the orientation adjustment motor 801 drives the pallet 802 to rotate, the arc-shaped sliding plate 14 slides synchronously along the slide rail 15, providing guidance and support for the rotation of the pallet 802. This structure avoids the situation where the pallet 802 is supported only by the output shaft of the orientation adjustment motor 801, reduces the shaking during the rotation process, improves the rotation positioning accuracy of the anti-slip stabilizing mechanism, and ensures that the side abutment adjustment module and the top pressing module can accurately align with the target position of the workpiece.

[0043] Another alternative embodiment based on the design of mounting bracket 13, arc-shaped slide plate 14, and slide rail 15: an annular mounting seat can be fixed on the tray 802, and the inner and outer walls of the annular mounting seat are provided with double arc-shaped slide rails; a matching annular slide block is fixed to the bottom of the placement tray 12, and the inner and outer sides of the annular slide block are provided with rolling element retainers, with precision balls embedded in the retainers; the double arc-shaped slide rails have grease storage grooves, and the annular slide block has a connected grease nipple. This embodiment optimizes the original single slide rail into a "double slide rail + ball + oil storage" structure. The double slide rails provide bidirectional guidance to improve the load-bearing capacity, the balls change sliding friction into rolling friction to reduce wear, the oil storage groove and grease nipple facilitate maintenance, and can also counteract the rotational radial force to prevent jamming, making it more suitable for processing scenarios with high-frequency rotational adjustments.

[0044] Refer to the instruction manual appendix Figure 4 and Figure 5 An arc-shaped limiting block 16 is fixedly connected to the arc-shaped sliding plate 14, and a matching annular limiting groove 17 is provided on the inner side of the slide rail 15. The arc-shaped limiting block 16 is slidably disposed in the annular limiting groove 17.

[0045] It should be noted that the arc-shaped limiting block 16 is fixed on the arc-shaped sliding plate 14 and slidably disposed in the annular limiting groove 17 inside the slide rail 15. This can limit the axial displacement of the arc-shaped sliding plate 14 in the direction perpendicular to the slide rail 15, preventing the arc-shaped sliding plate 14 from coming off the slide rail 15 during sliding. Even if strong impact vibration occurs during processing, the cooperation between the arc-shaped limiting block 16 and the annular limiting groove 17 can ensure that the arc-shaped sliding plate 14 remains stably in the slide rail 15, ensuring the normal operation of the orientation adjustment module and the entire anti-slip stabilization mechanism, and improving the safety and reliability of the support frame.

[0046] Working principle:

[0047] First, the vertical rotation motor 4 drives the rotating cylinder 3 to rotate around the axis of the U-shaped support frame 2, which can adjust the vertical tilt angle of the workpiece; the horizontal rotation motor 5 drives the support plate 6 to rotate the support plate 9, the placement plate 12 and the workpiece, realizing 360° horizontal station switching to meet diverse processing angle requirements.

[0048] 2. After the workpiece is placed on the placement tray 12, the clamping mechanism first starts the foundation fixation: the cylinder 701 of the side clamping module pushes the L-shaped pusher 702 to fit against the side of the workpiece, forming a lateral positioning; then by rotating the knob 704 of the top pressing module, the threaded rod 703 drives the pressure plate 705 to press down on the top of the workpiece, completing the "side-top" double foundation fixation.

[0049] 3. If the workpiece tilts or vibrates during processing, the anti-slip stabilizing mechanism activates a secondary protection mechanism: the orientation adjustment motor 801 drives the support plate 802 to rotate, causing the side contact adjustment module and the top pressing module 2 to rotate synchronously. During the process, the arc-shaped sliding plate 14 on the mounting frame 13 slides along the slide rail 15 at the bottom of the placement plate 12, and the arc-shaped limiting block 16 is limited in the annular limiting groove 17 to ensure rotational stability. When the workpiece is moved to its lowest point, the cylinder 2 803 pushes the L-shaped pusher 2 804 through the groove of the connecting frame 10 to fit against the side of the workpiece. Then, the cylinder 3 805 drives the pressure plate 2 806 to press down on the top of the workpiece, forming a targeted anti-fall fixation to prevent the workpiece from sliding down the inclined surface or displacing due to vibration, thus ensuring processing accuracy.

[0050] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
