[0001] This invention relates to the field of production equipment technology, and more specifically, to a three-dimensional free-rotating worktable for receiving parts. Background Technology

[0002] In manufacturing production lines, parts workbenches are commonly used and essential auxiliary production equipment. They are mainly used to assist in parts receiving operations. Traditional fixed workbenches are common in production lines. The workbenches cannot move. When operators are inspecting or welding parts, they need to move or flip the parts back and forth. When the parts are large, two people are required to work together, and the labor load is heavy.

[0003] Therefore, it is necessary to propose a three-dimensional free-rotation worktable for supporting parts in order to at least partially solve the problems existing in the prior art. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the present invention provides a three-dimensional free-rotating worktable for receiving parts, comprising: a rotating mechanism disposed at the bottom of a support frame for rotating the support frame horizontally; a flipping mechanism disposed at the top of the support frame, the flipping mechanism being provided with a clamping mechanism for clamping parts, the flipping mechanism being used to flip the parts vertically; and a pressure holding device for controlling the pressure of the brake of the flipping mechanism and the clamping of the clamping mechanism.

[0006] Preferably, the flipping mechanism includes: a flipping shaft rotatably mounted on a support frame, with a flipping drive unit and a brake disc respectively at both ends of the flipping shaft, and a brake on the support frame, the brake being used to apply a clamping force to the brake disc or release the clamping force.

[0007] Preferably, the clamping mechanism includes a fixed clamping assembly and a movable clamping assembly disposed on the flipping shaft, wherein the fixed clamping assembly is used to limit the position of the part, and the movable clamping assembly is used to apply clamping force to the part.

[0008] Preferably, the movable clamping assembly includes: a clamping drive unit, which is mounted on a flip shaft via a fixing member; a clamping body, on which a clamping arm is connected, the end of the clamping arm away from the clamping body being hinged to the telescopic end of the clamping drive unit; and a limiting rod is also provided on the clamping arm, the end of the limiting rod away from the clamping arm being rotatably connected to the fixing member.

[0009] Preferably, the top of the fastener is further provided with an elastic support assembly, which is used to abut against the clamping arm when the part is clamped.

[0010] The elastic support assembly includes: an elastic block disposed on the top of the fixing member, the top of the elastic block having an abutment block, and the top of the abutment block having a limiting groove corresponding to the clamping arm.

[0011] Preferably, the fixing and clamping assembly includes: multiple limiting members for limiting the side of the part; and multiple supporting bodies for supporting the bottom surface of the part, wherein the part is clamped between the supporting bodies and the clamping bodies.

[0012] Preferably, the pressure-holding device includes: a pressure-holding valve for maintaining the clamping force of the flipping mechanism when braking at a first preset value, and maintaining the clamping force of the clamping mechanism when clamping the part at a second preset value; and an air valve for controlling the opening or closing of the air source.

[0013] Preferably, the rotating mechanism includes: a mounting base for connecting to the plane to be fixed; a horizontal drive unit disposed on the mounting base, the power output end of which is connected to the support frame; and multiple wheels at the bottom of the support frame for supporting the horizontal rotation of the support frame.

[0014] Preferably, it also includes a monitoring and control module for real-time monitoring of the clamping force of the clamping mechanism on the part, and for initiating different levels of safety response based on changes in the clamping force.

[0015] Preferably, the clamping force variation of the clamping mechanism includes:

[0016] The clamping force of the clamping mechanism decreases, and the clamping force is predicted. If the clamping force can be maintained at or above the safety threshold within a set time, a first-level alarm is issued.

[0017] The clamping force of the clamping mechanism decreases. The clamping force is predicted. If the clamping force will be lower than the safety threshold within a set time, the air passage connected to the clamping mechanism is cut off, and the flipping mechanism is controlled to flip the part to the top. Then, the brake disc is locked by the brake and a secondary alarm is issued.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] The three-dimensional free-rotating worktable for receiving parts described in this invention allows parts to rotate horizontally and flip vertically. The posture of the parts can be quickly adjusted through the rotation and flipping mechanisms, thereby achieving 360-degree free rotation of the parts. This breaks the limitations of single-dimensional operation and changes the traditional welding operation mode in which operators need to move or flip parts back and forth.

Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0037] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0038] like Figure 1 and Figure 2 As shown, the present invention provides a three-dimensional free-rotating worktable for receiving parts, comprising: a rotating mechanism 2 disposed at the bottom of a support frame 1 for rotating the support frame 1 horizontally; a flipping mechanism 3 disposed at the top of the support frame 1, wherein the flipping mechanism 3 is provided with a clamping mechanism 4 for clamping parts 9, and the flipping mechanism 3 is used to flip parts 9 vertically; and a pressure holding device for controlling the pressure of the brake of the flipping mechanism 3 and the clamping of the clamping mechanism 4.

[0039] The rotating mechanism 2 enables the entire support frame 1 to rotate horizontally 360 degrees, thereby driving the flipping mechanism 3, clamping mechanism 4, and part 9 on the support frame 1 to rotate synchronously; the flipping mechanism 3 can generate a 360-degree vertical flip, thereby driving the clamping mechanism 4 and part 9 on the flipping mechanism 3 to flip synchronously; the clamping mechanism 4 is configured according to the shape of part 9 to stably clamp part 9; both the flipping mechanism 3 and the clamping mechanism 4 are pneumatically controlled, and the pressure of both during operation is stably controlled by a pressure holding device to ensure the stability of part 9 during rotation and prevent part 9 from accidentally falling off.

[0040] Through the above design, part 9 can be rotated horizontally and flipped vertically. The posture of part 9 can be quickly adjusted through the rotation mechanism 2 and the flipping mechanism 3, thereby realizing the 360-degree free rotation function of part 9. This breaks the single-dimensional operation limitation and changes the operation mode in traditional welding operations where operators need to move or flip parts back and forth. This effectively reduces the labor load of operators, improves work efficiency, and enables independent operation by a single person.

[0041] like Figure 3 As shown, in one embodiment, the flipping mechanism 3 includes: a flipping shaft 31 rotatably mounted on the support frame 1, with a flipping drive unit 32 and a brake disc 33 respectively provided at both ends of the flipping shaft 31, and a brake 34 provided on the support frame 1, the brake 34 being used to apply a clamping force to the brake disc 33 or release the clamping force.

[0042] The two ends of the tilting shaft 31 are provided with rotating shafts, and the top of the support frame 1 is provided with a bearing seat. The bearing seat is provided with a bearing (such as a thrust roller bearing) that is compatible with the rotating shaft. The two rotating shafts are respectively connected to the tilting drive unit 32 and the brake disc 33.

[0043] like Figure 4 As shown, the flipping drive unit 32 is a drive disk or a drive motor. The drive disk can be manually controlled by the operator to rotate the flipping shaft 31, and the drive motor can be electrically controlled to rotate the flipping shaft 31.

[0044] like Figure 5 As shown, the brake disc 33 cooperates with the brake 34 to fix the rotational position of the tilting shaft 31. The brake 34 can be a vacuum disc brake. The brake piston in the brake 34 is pushed by compressed gas. The extended end of the brake piston is provided with a brake block that contacts the brake disc 33. The movement of the brake block driven by the piston can apply or release the clamping force to the brake disc 33. This enables fast and precise braking at any angle during the tilting process, providing the operator with flexible and reliable operation control.

[0045] like Figure 6 and Figure 7As shown, in one embodiment, the clamping mechanism 4 includes a fixed clamping component 5 and a movable clamping component 6 disposed on the flip shaft 31. The fixed clamping component 5 is used to limit the position of the part 9, and the movable clamping component 6 is used to apply clamping force to the part 9.

[0046] When clamping part 9, the flipping mechanism 3 rotates to the clamping position, i.e. Figure 1 The part 9 is placed in the position shown, and then the part 9 is placed on the fixed clamping assembly 5. The fixed clamping assembly 5 can support the bottom of the part 9 and limit the side of the part 9. After the part 9 is placed in place, the movable clamping assembly 6 applies a clamping force to the part 9, and the part 9 is clamped between the fixed clamping assembly 5 and the movable clamping assembly 6, thereby achieving the clamping and fixing of the part 9.

[0047] like Figure 8 As shown, in one embodiment, the movable clamping assembly 6 includes: a clamping drive unit 61, which is mounted on the flip shaft 31 via a fixing member 62; a clamping body 63, on which a clamping arm 64 is connected, the end of the clamping arm 64 away from the clamping body 63 being hinged to the telescopic end of the clamping drive unit 61; and a limiting rod 65 is also provided on the clamping arm 64, the end of the limiting rod 65 away from the clamping arm 64 being rotatably connected to the fixing member 62.

[0048] The clamping drive unit 61 uses a cylinder. The end of the cylinder's telescopic rod is a telescopic end, which is hinged to the clamping arm 64. By extending and retracting the telescopic end of the cylinder, the clamping arm 64 can be driven to move, achieving rapid clamping and releasing. This can stably fix the part 9 and effectively prevent the part 9 from becoming loose or falling during operation.

[0049] Specifically, such as Figure 6 The image shows the state when the active clamping assembly 6 is open. When the telescopic end of the clamping drive unit 61 retracts, both the clamping arm 64 and the clamping body 63 move, causing the clamping body 63 to move away from the part 9, thereby releasing the clamping of the part 9.

[0050] like Figure 7 The diagram shows the state when the movable clamping assembly 6 is clamping. When the telescopic end of the clamping drive unit 61 extends, both the clamping arm 64 and the clamping body 63 move, causing the clamping body 63 to move towards the part 9, thereby applying a clamping force to the part 9 and clamping the part 9 between the movable clamping assembly 6 and the fixed clamping assembly 5.

[0051] like Figure 8 As shown, in one embodiment, the top of the fixing member 62 is also provided with an elastic support component 66, which is used to abut against the clamping arm 64 when the part 9 is clamped.

[0052] The elastic support assembly 66 includes: an elastic block 661 disposed on the top of the fixing member 62, the top of the elastic block 661 being provided with an abutment block 662, and the top of the abutment block 662 being provided with a limiting groove 663 corresponding to the clamping arm 64.

[0053] Specific examples Figure 7 As shown, when the movable clamping assembly 6 clamps, the clamping arm 64 contacts the elastic support assembly 66, and the clamping arm 64 is placed in the limiting groove 663. As the clamping force on the part 9 increases, the force of the clamping arm 64 on the elastic support assembly 66 increases, thereby compressing the elastic block 661. The elastic block 661 provides elastic support for the clamping arm 64, thereby playing a vibration damping role when the part 9 rotates, preventing the position of the part 9 from shifting, and further ensuring the stability of clamping the part 9.

[0054] In addition, the upper part of the elastic block 661 can be triangular or trapezoidal in cross section, and the bottom of the abutment block 662 is provided with a groove corresponding to the upper part of the elastic block 661, so that the elastic block 661 can provide elastic support to the abutment block 662 in multiple directions, thereby providing vibration reduction in multiple directions for the clamping arm 64 and improving the stability of clamping the part 9.

[0055] like Figure 9 As shown, the clamping body 63 includes: a fixing block 631 connected to the clamping arm 64 and a clamping block 632 for contacting the part 9, and an elastic layer is provided between the clamping block 632 and the fixing block 631.

[0056] The fixed block 631 and the clamping block 632 are connected by an elastic layer, which enables the clamping body 63 to elastically abut against the part 9, further reducing vibration.

[0057] In addition, a pressure detector may be selectively provided in the elastic layer. The pressure detector can directly detect the change in the clamping force on part 9, so as to know whether the clamping mechanism 4 clamps part 9.

[0058] like Figure 6 and Figure 10 As shown, in one embodiment, the fixing clamping assembly 5 includes: a plurality of limiting members 51 for limiting the side of the part 9; a plurality of supporting bodies 52 for supporting the bottom surface of the part 9, wherein the part 9 is clamped between the supporting bodies 52 and the clamping bodies 63.

[0059] Furthermore, the flip shaft 31 is provided with a plurality of support plates 311, each support plate 311 is provided with a limiting member 51, and the flip shaft 31 is also provided with two limiting members 51; the limiting member 51 includes a limiting plate 511 and a limiting post 512 arranged at intervals, and a supporting body 52 is provided between the limiting plate 511 and the limiting post 512, and an elastic layer is provided between the supporting body 52 and the flip shaft 31, and between the supporting body 52 and the supporting plate 311.

[0060] The frame of part 9 is placed between the limiting plate 511 and the limiting post 512 to limit the side of part 9. The supporting body 52 supports the bottom of the frame of part 9. Then, the clamping body 63 applies clamping force to the top of the frame of part 9, so that the frame of part 9 is clamped between the clamping body 63 and the supporting body 52, thereby clamping part 9.

[0061] An elastic layer is provided between the support body 52, the support plate 311, and the flipping shaft 31, so that the part 9 can be elastically clamped between the support body 52 and the clamping body 63, preventing vibration from affecting the clamping stability of the part 9.

[0062] like Figures 4-5 , Figures 11-12 As shown, in one embodiment, the pressure-holding device includes: a pressure-holding valve 7, used to maintain the clamping force of the flipping mechanism 3 when braking at a first preset value, and to maintain the clamping force of the clamping mechanism 4 when clamping the part 9 at a second preset value; and an air valve 8, used to control the opening or closing of the air source.

[0063] Both the pressure holding valve 7 and the air valve 8 are mounted on the support frame 1. By adjusting the air supply and exhaust through the pressure holding valve 7, the air pressure (used to push the brake piston) in the brake 34 can be kept stable, that is, the clamping force is kept at the first preset value. The air pressure in the clamping drive part 61, i.e., the cylinder, is kept stable, that is, the clamping force is kept at the second preset value. It will not be affected when the switch is accidentally touched or the air source is disconnected during operation, and the stability of the clamping force and clamping force can still be maintained, ensuring safety protection during operation. The air valve 8 can control the opening and closing of the air source.

[0064] like Figure 13 As shown, in one embodiment, the rotating mechanism 2 includes: a mounting base 21 for connecting to the plane to be fixed; a horizontal drive unit 22 disposed on the mounting base 21, the power output end of which is connected to the support frame 1; and a plurality of wheels 11 provided at the bottom of the support frame 1 for supporting the horizontal rotation of the support frame 1.

[0065] Mounting base 21 is fixed to the surface to be fixed by screws. A horizontal drive unit 22 is fixedly mounted on mounting base 21. A drive device such as a servo motor or electric motor can be used. The power output end of the horizontal drive unit 22 is connected to the support frame 1 through a flange to achieve fixation. Thus, when the horizontal drive unit 22 is working, it can drive the support frame 1 to rotate as a whole. The multiple wheels 11 at the bottom of the support frame 1 are universal wheels. When the support frame 1 rotates, the wheels 11 support the movement of the support frame 1.

[0066] The outer surface of the wheel 11 is covered with an elastic rubber layer, which can dampen the bearing frame 1 when it rotates and effectively suppress vibration transmission.

[0067] Alternatively, the horizontal drive unit 22 can be omitted, and a rolling bearing can be used instead. The rotation of the entire support frame 1 can be achieved by manual force applied by the operator.

[0068] In one embodiment, it further includes: a monitoring and control module for real-time monitoring of the clamping force of the clamping mechanism 4 on the part 9, and for initiating different levels of safety response based on changes in the clamping force.

[0069] Specifically, the changes in the clamping force of the clamping mechanism 4 include:

[0070] The clamping force of the clamping mechanism 4 decreases. The clamping force is predicted. If the clamping force can be maintained at or above the safety threshold within a set time, a first-level alarm is issued.

[0071] The clamping force of the clamping mechanism 4 decreases. The clamping force is predicted. If the clamping force will be lower than the safety threshold within a set time, the air passage connected to the clamping mechanism 4 is cut off, and the flipping mechanism 3 is controlled to flip the part 9 to the top. Then, the brake disc 33 is locked by the brake 34, and a secondary alarm prompt is issued at the same time.

[0072] The following formula is used to predict the change in clamping force over a set time period:

[0073]

[0074] in, The predicted time required for the clamping force to decrease from the current pressure value to the safety threshold. This represents the current pressure value of the clamping force. As a safety threshold, This represents the rate of change of clamping force per unit time, i.e., the rate of decrease in clamping force. The magnitude of the pressure change of the clamping force at adjacent acquisition times. The time interval between adjacent acquisition times;

[0075] like , If a time setting is set (which can be set according to actual conditions, such as 3 minutes), a level one alarm will be issued, indicating that the clamping force is slowly decreasing and the air circuit may be slowly leaking. This prompts the operator to check and take measures in time to prevent part 9 from falling off.

[0076] like If the alarm is triggered, a level 2 alarm will be issued and an emergency response will be triggered, namely, the air circuit connected to the clamping mechanism 4 will be cut off, the flipping mechanism 3 will be controlled to flip the part 9 to the top, and the brake disc 33 will be locked by the brake 34.

[0077] When a level 2 alarm is issued, it indicates that the air leakage rate in the air circuit is relatively fast. It is necessary to quickly cut off the air circuit connected to the clamping mechanism 4 to maintain the air pressure in the clamping drive unit 61 (i.e., the cylinder) and prevent the air pressure from continuing to drop. This ensures that the clamping force is not reduced to the safety threshold before emergency measures are taken to prevent the part 9 from falling off. Then, the flipping mechanism 3 is flipped to the initial position, that is, the position where the part 9 was initially placed. The fixed clamping assembly 5 can support the part 9 to further prevent the part 9 from falling off and ensure the safety of the operation.

[0078] In one embodiment, it further includes: an interlocking control module that locks the flipping mechanism 3 and the rotating mechanism 2 when clamping the part 9;

[0079] Before flipping part 9, the clamping force of clamping mechanism 4 is monitored in real time. When the clamping force reaches the second preset value, the locking of flipping mechanism 3 and rotating mechanism 2 is released.

[0080] When clamping part 9, since clamping mechanism 4 is holding part 9, the clamping force for rotation and flipping has not yet been met (the clamping force has not reached the second preset value). Therefore, at this stage, flipping mechanism 3 and rotating mechanism 2 need to be locked. That is, with the cooperation of brake 34 and brake disc 33, flipping mechanism 3 cannot flip, and horizontal drive unit 22 cannot work. Then, before flipping part 9, the clamping force needs to be monitored in real time. When the clamping force reaches the second preset value, the lock on flipping mechanism 3 and rotating mechanism 2 can be released, and part 9 can be flipped and rotated to ensure safety.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0082] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.
