Description

Technical Field

[0001] This utility model mainly relates to the field of workbench technology, specifically to a three-station flip workbench. Background Technology

[0002] In machining, assembly and other production processes, it is often necessary to operate on workpieces from different angles and positions. Workpieces are usually placed on a workbench for the corresponding operations.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Traditional workbenches typically only provide a single workstation. If multi-faceted processing or assembly of a workpiece is required, the workpiece position needs to be adjusted manually multiple times. This is not only inefficient, but also prone to causing positional deviations in the workpiece during repeated adjustments, affecting processing accuracy and assembly quality, and failing to meet actual production needs.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] This utility model provides a three-station flip-top worktable to solve the technical problems existing in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows: a three-station flipping worktable, comprising a base and three workstation platforms. A rotating mechanism is provided between the base and the workstation platforms. The rotating mechanism includes a central rotating shaft, a rotating disk, a drive motor, and a linkage component. The central rotating shaft is vertically arranged in the middle of the base and passes through the interior of the base. The rotating disk is fixedly installed on the top of the central rotating shaft, and the drive motor is fixedly installed on the bottom of the base. The three workstation platforms are distributed on the upper surface of the rotating disk, and a flipping component is provided at the bottom of each workstation platform. A workpiece positioning component is provided on the upper surface of each of the three workstation platforms. Three workstation positioning components are provided inside the base, and the workstation positioning components correspond to the workpiece positioning components.

[0010] Furthermore, the output end of the drive motor is connected to a main shaft, a drive gear is mounted on the main shaft, and the linkage assembly includes a driven gear that meshes with the drive gear, the driven gear being fixedly sleeved on the central shaft.

[0011] Furthermore, the workstation platforms are distributed at 120-degree intervals on the upper surface of the rotating disk.

[0012] Furthermore, the flipping assembly includes a connecting shaft fixedly connected to the center of the top of the rotating disk, the flipping shaft passing laterally through the inside of the workstation platform, the workstation platform being rotatably connected to the connecting shaft via the flipping shaft, a flipping cylinder being provided at the bottom of the workstation platform, multiple hinge seats being provided on the upper surface of the rotating disk, the cylinder body of the flipping cylinder being hinged to the hinge seats, and the piston rod of the flipping cylinder being hinged to the bottom of the workstation platform.

[0013] Furthermore, the workpiece positioning assembly includes multiple motion slots formed on the upper surface of the workstation platform. A screw is rotatably connected inside the motion slot, and a moving block is threadedly connected to the outside of the screw. The moving block is slidably disposed inside the motion slot. An adjusting block is installed on the side wall of the workstation platform through the screw. Multiple adjusting slots are formed on the outer side wall of the workstation platform. The adjusting block is rotatably disposed inside the adjusting slot. A clamping block is fixedly connected to the top of the moving block, and a limit group is provided on one side of the adjusting block.

[0014] Furthermore, the limiting component includes a limiting groove formed on one side of the adjusting block, an arc-shaped groove formed on one side of the outer wall of the workstation platform adjacent to the adjusting groove, an arc-shaped slider slidably installed on the inner wall of the arc-shaped groove, a protruding rod fixedly connected to the front end of the arc-shaped slider, a limiting rod fixedly connected to one end of the arc-shaped slider, and the limiting rod being inserted into the interior of the arc-shaped groove.

[0015] Furthermore, the workstation positioning component includes three drive cylinders fixedly installed on the inner bottom wall of the base. The piston rod of the drive cylinder is equipped with a connecting plate. Multiple positioning pins are fixedly connected to the upper surface of the connecting plate. Multiple through holes are opened on the rotating disk. Multiple positioning holes are opened on the lower surface of the workstation platform.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This utility model is reasonably designed. By setting up three workstation platforms, it can simultaneously perform different processes on three different workpieces, which greatly improves work efficiency. The rotating disk can realize the rapid switching of workstation platforms under the drive of the drive motor. With the help of the tilting cylinder, the workstation platform can be tilted to a suitable angle, thereby meeting different processing and assembly needs and expanding the applicability of the workbench.

[0019] The precise positioning of the workstation platform can be achieved through the positioning pin and positioning hole, ensuring the accuracy of processing and assembly.

[0020] The adjustable clamping blocks allow the table to accommodate workpieces of different shapes and sizes, thus improving its versatility.

[0021] By using the insertion and limiting between the limiting rod and the limiting groove, the adjusting block can be positioned to prevent the clamping block from shifting, which would result in insufficient clamping of the workpiece and ensure the clamping tightness of the workpiece.

[0035] See attached document Figure 1-6A three-station flip-over worktable includes a base 1 and three workstation platforms 2. A rotating mechanism is provided between the base 1 and the workstation platforms 2. The rotating mechanism includes a central rotating shaft 3, a rotating disk 4, a drive motor 5, and a linkage component. The central rotating shaft 3 is vertically arranged in the middle of the base 1 and passes through the interior of the base 1. The rotating disk 4 is fixedly installed on the top of the central rotating shaft 3, and the drive motor 5 is fixedly installed on the bottom of the base 1. The three workstation platforms 2 are distributed on the upper surface of the rotating disk 4, and the bottom of the workstation platforms 2 is provided with a flip-over component. The upper surface of each of the three workstation platforms 2 is provided with a workpiece positioning component. The base 1 contains three workstation positioning components, which correspond to the workpiece positioning components.

[0036] In this embodiment, the output end of the drive motor 5 is connected to the main rotating shaft 6, the main rotating shaft 6 is equipped with a drive gear 7, and the linkage component includes a driven gear 8 that meshes with the drive gear 7. The driven gear 8 is fixedly sleeved on the central rotating shaft 3.

[0037] It should be noted that when a workstation needs to be switched, the drive motor 5 is started to drive the main shaft 6 to rotate, the driving gear 7 drives the driven gear 8 to rotate, thereby causing the central shaft 3 to drive the rotating disk 4 to rotate. The photoelectric sensor detects the rotation angle of the rotating disk 4 in real time. When the rotating disk 4 rotates to the designated workstation, the drive motor 5 stops running.

[0038] In this embodiment, the workstation platforms 2 are distributed at 120-degree intervals on the upper surface of the rotating disk 4.

[0039] It should be noted that the three workstation platforms 2 are evenly distributed on the upper surface of the rotating disk 4 to facilitate processing and assembly.

[0040] In this embodiment, the flipping assembly includes a connecting shaft 9 fixedly connected to the top center of the rotating disk 4, a flipping shaft 10 passing laterally through the inside of the workstation platform 2, and the workstation platform 2 being rotatably connected to the connecting shaft 9 via the flipping shaft 10. A flipping cylinder 11 is provided at the bottom of the workstation platform 2, and multiple hinge seats 12 are provided on the upper surface of the rotating disk 4. The cylinder body of the flipping cylinder 11 is hinged to the hinge seat 12, and the piston rod of the flipping cylinder 11 is hinged to the bottom of the workstation platform 2.

[0041] It should be noted that when the angle of the workstation platform 2 needs to be adjusted, the tilting cylinder 11 is activated, and the extension and retraction of the piston rod pushes the workstation platform 2 to rotate around the tilting axis 10 until the required angle is reached.

[0042] In this embodiment, the workpiece positioning assembly includes multiple motion slots 13 formed on the upper surface of the workstation platform 2. A screw 14 is rotatably connected inside the motion slot 13, and a moving block 15 is threadedly connected to the outside of the screw 14. The moving block 15 is slidably disposed inside the motion slot 13. An adjusting block 16 is installed on the screw 14 through the side wall of the workstation platform 2. Multiple adjusting slots 17 are formed on the outer side wall of the workstation platform 2. The adjusting block 16 is rotatably disposed inside the adjusting slot 17. A clamping block 18 is fixedly connected to the top of the moving block 15, and a limiting component is provided on one side of the adjusting block 16.

[0043] It should be noted that by rotating the adjusting block 16, the screw 14 is driven to rotate, which causes the moving block 15 to move along the inside of the moving groove 13, thereby moving the clamping block 18 and clamping and fixing the workpiece through the clamping block 18.

[0044] In this embodiment, the limiting component includes a limiting groove 19 opened on one side of the adjusting block 16, an arc-shaped groove 20 opened on one side of the outer wall of the workstation platform 2 adjacent to the adjusting groove 17, an arc-shaped slider 21 is slidably installed on the inner wall of the arc-shaped groove 20, a protruding rod 22 is fixedly connected to the front end of the arc-shaped slider 21, a limiting rod 23 is fixedly connected to one end of the arc-shaped slider 21, and the limiting rod 23 is inserted into the interior of the arc-shaped groove 20.

[0045] It should be noted that the protruding rod 22 is easy to operate. The protruding rod 22 is used to make the arc-shaped slider 21 slide along the inner wall of the arc-shaped groove 20, which drives the limiting rod 23 to move and insert into the interior of the limiting groove 19, thereby limiting the adjustment block 16 and preventing the workpiece from shifting.

[0046] In this embodiment, the workstation positioning component includes three drive cylinders 24 fixedly installed on the inner bottom wall of the base 1. The piston rod of the drive cylinder 24 is equipped with a connecting plate 25. Multiple positioning pins 26 are fixedly connected to the upper surface of the connecting plate 25. Multiple through holes 27 are opened on the rotating disk 4. Multiple positioning holes 28 are opened on the lower surface of the workstation platform 2. The positioning pins 26 can be vertically inserted into the positioning holes 28 by passing through the through holes 27.

[0047] It should be noted that when the rotating disk 4 drives the workstation platform 2 to rotate to the designated workstation, it stops rotating. The drive cylinder 24 drives the connecting disk 25 and the positioning pin 26 to rise upward, so that the positioning pin 26 passes through the inside of the through hole 27 and is inserted into the positioning hole 28, thus completing the precise positioning of the workstation.

[0048] The working principle of this utility model is as follows: In use, the workpiece is first placed on the corresponding workstation platform 2. Rotating the adjusting block 16 drives the screw 14 to rotate, causing the moving block 15 to move along the inside of the motion groove 13, thus moving the clamping block 18. The clamping block 18 clamps and fixes the workpiece. The arc-shaped slider 21 slides along the inner wall of the arc-shaped groove 20, causing the limiting rod 23 to move and insert into the limiting groove 19, limiting the adjusting block 16 and preventing workpiece displacement. When a workstation needs to be switched, the drive motor 5 is started to drive the main rotating shaft 6 to rotate. The driving gear 7 drives the driven gear 8 to rotate, thereby causing the central rotating shaft 3 to drive the rotating disk 4 to rotate. The sensor detects the rotation angle of the rotating disk 4 in real time. When the rotating disk 4 rotates to the designated work position, the drive motor 5 stops running. At this time, the drive cylinder 24 drives the connecting disk 25 and the positioning pin 26 to rise, so that the positioning pin 26 passes through the inside of the through hole 27 and is inserted into the positioning hole 28, completing the precise positioning of the work position. When it is necessary to adjust the angle of the work position platform 2, the tilting cylinder 11 is activated, and the extension and retraction of the piston rod pushes the work position platform 2 to tilt around the tilting axis 10 until the required angle is reached. During the entire operation, different processing or assembly of workpieces on three work position platforms 2 can be performed simultaneously, which greatly improves production efficiency and processing accuracy.

[0049] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, 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 various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
