Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and in particular to a processing apparatus. Background Technology

[0002] Welding pliers are a widely used welding tool. Their assembly process typically involves drilling holes in the pliers body, tapping threads, and securing assembly pieces with screws. In a typical welding pliers structure, the aforementioned machining operations are required on both the front and back of the pliers body. For example, corresponding positions on both sides of the pliers body need to be drilled with mounting holes, internal threads machined, and screws finally screwed in to secure the assembly pieces. Therefore, the actual assembly process requires completing the entire process of drilling holes on both sides, tapping threads on both sides, and screwing screws on both sides.

[0003] Both sides of the welding clamp need to be drilled, tapped, and screwed. Most existing equipment can only complete single-sided processing. When the other side needs to be processed, the workpiece still needs to be manually removed from the fixture, flipped, and re-clamped. This not only increases the auxiliary time, but the positioning deviation caused by the second clamping directly affects the positional accuracy of drilling and tapping, which in turn affects the smoothness of subsequent screw assembly and the final product assembly quality. Summary of the Invention

[0004] The purpose of this invention is to provide a processing apparatus to solve the problems existing in the prior art, reduce processing time, improve the positional accuracy of drilling and tapping, and improve the smoothness of subsequent screw assembly and the assembly quality of the final product.

[0005] To achieve the above objectives, the present invention provides the following solution: The present invention provides a processing device, including a clamping mechanism, a flipping mechanism, and a working mechanism. The clamping mechanism is used to clamp and position a workpiece; the flipping mechanism is connected to the clamping mechanism and is used to drive the clamping mechanism and the workpiece thereon to flip; the working mechanism is disposed on one side of the clamping mechanism for processing the workpiece.

[0006] In one embodiment, the clamping mechanism includes a mounting base, a positioning member, and a clamping member. The positioning member is disposed on the mounting base and is used to position the workpiece. The clamping member is disposed on the mounting base and is used to approach the positioning member and press the workpiece against the positioning member to achieve clamping and positioning of the workpiece; it is also used to move away from the positioning member and release the workpiece. The free end of the flipping mechanism is connected to the mounting base to drive the mounting base to rotate, thereby causing the positioning member and the clamping member to rotate.

[0007] In one embodiment, the clamping member includes a movable member and a linear drive mechanism. The movable member is disposed on one side of the positioning member and slidably connected to the mounting base. The linear drive mechanism is used to drive the movable member closer to the positioning member and press the workpiece onto the positioning member; it is also used to drive the movable member away from the positioning member and release the workpiece.

[0008] In one embodiment, the linear drive mechanism includes a rotary motor, a pressure rod, and an elastic element. The moving member is provided with a first driving surface and a second driving surface. The pressure rod has a driving portion that is closer to the positioning member than the first driving surface. The elastic element is farther from the positioning member than the second driving surface and is used to apply a spring force toward the positioning member to the moving member. The output end of the rotary motor is fixedly connected to the pressure rod. The rotary motor is used to drive the pressure rod to swing downward about the axis of the output end of the rotary motor to abut against the first driving surface and the moving member to overcome the spring force of the elastic element so that the moving member moves away from the positioning member. The rotary motor is also used to drive the pressure rod to swing upward about the axis of the output end of the rotary motor so that the moving member moves closer to the positioning member under the action of the spring force of the elastic element.

[0009] In one embodiment, the end of the movable member used to contact the workpiece is provided with a V-groove.

[0010] In one embodiment, a support component is also included. The clamping mechanism is used to clamp and position one end of the workpiece; the support component is used to support and release the other end of the workpiece; during processing by the working mechanism, the support component supports the other end of the workpiece; before the flipping mechanism flips, the support component releases the other end of the workpiece.

[0011] In one embodiment, the support component is capable of vertical movement to support and release the other end of the workpiece.

[0012] In one embodiment, the flipping mechanism includes a rotary drive and a connecting member, wherein the rotary drive is fixedly disposed; the free end of the rotary drive is fixedly connected to the connecting member, and the connecting member is used to connect to the mounting base and drive the mounting base to rotate.

[0013] In one embodiment, the flipping mechanism further includes a moving component for moving the rotary drive and its connected connector closer to or away from the mounting base, thereby connecting and disconnecting the connector from the mounting base.

[0014] In one implementation, the working mechanism is configured as three.

[0015] The present invention achieves the following technical effects compared to the prior art: This invention discloses a processing device. By setting a flipping mechanism, which can be connected to a clamping mechanism and used to drive the clamping mechanism to flip so that the front and back sides of the workpiece on the clamping mechanism alternate, the workpiece is processed by the working mechanism. There is no need for manual removal of the workpiece from the fixture, flipping and re-clamping, eliminating the auxiliary time for the workpiece to flow between different processes. It realizes continuous and automated double-sided processing, which significantly improves processing efficiency. After flipping, the position of the workpiece only changes in spatial posture and does not produce relative displacement. This avoids the positioning error introduced by the re-clamping after disassembly in the traditional solution, and ensures that the relative position reference is consistent between the front and back sides during processing. This greatly improves the positional accuracy of drilling and tapping, which is beneficial to the smoothness of subsequent screw assembly and improves the final assembly quality of the product.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] The purpose of this invention is to provide a processing apparatus to solve the problems existing in the prior art, reduce processing time, improve the positional accuracy of drilling and tapping, and improve the smoothness of subsequent screw assembly and the assembly quality of the final product.

[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1-5 As shown, the present invention provides a processing device, including a clamping mechanism 1, a flipping mechanism 2, and a working mechanism 3. The clamping mechanism 1 is used to clamp and position the workpiece 5; the flipping mechanism 2 can be connected to the clamping mechanism 1 and is used to drive the clamping mechanism 1 and the workpiece 5 thereon to flip; the working mechanism 3 is disposed on one side of the clamping mechanism 1 for processing the workpiece 5.

[0022] This invention incorporates a flipping mechanism 2, which connects to a clamping mechanism 1 and drives the clamping mechanism 1 to flip, alternating the front and back sides of the workpiece 5. The workpiece 5 is then processed using a working mechanism 3. This eliminates the need for manual removal of the workpiece 5 from the fixture, flipping, and re-clamping, thus eliminating the auxiliary time required for the workpiece 5 to move between different processes. This achieves continuous and automated double-sided processing, significantly improving processing efficiency. After flipping, the workpiece 5's position only changes spatially, maintaining a fixed posture without relative displacement. This avoids the positioning errors introduced by re-clamping after disassembly in traditional solutions, ensuring consistent relative positional references between the back and front sides during processing. This greatly improves the positional accuracy of drilling and tapping, facilitating smoother subsequent screw assembly and enhancing the final assembly quality of the product.

[0023] It should be noted that the flipping action in the above embodiments can be a rotation around an axis at any angle, such as 90 degrees, 180 degrees, 45 degrees, etc., which needs to be determined according to the position of the part to be processed on the workpiece.

[0024] In one specific implementation, workpiece 5 may be a welding clamp.

[0025] In one embodiment, the clamping mechanism 1 includes a mounting base 11, a positioning member 12, and a clamping member 13. The positioning member 12 is disposed on the mounting base 11 and is used to position the workpiece 5. The clamping member 13 is disposed on the mounting base 11 and is used to approach the positioning member 12 and press the workpiece 5 onto the positioning member 12 to achieve clamping and positioning of the workpiece 5. It is also used to move away from the positioning member 12 and release the workpiece 5. The free end of the flipping mechanism 2 is connected to the mounting base 11 to drive the mounting base 1 to rotate 1, thereby causing the positioning member 12 and the clamping member 13 to rotate.

[0026] The positioning element 12 initially positions the workpiece 5 to determine its reference position. The positioning element 12 can be configured as a limiting protrusion, its shape adapted to the workpiece 5, allowing the limiting hole on the workpiece 5 to be directly inserted into the limiting protrusion. The clamping element 13 then applies clamping force to the positioned workpiece 5, forming a secondary constraint that ensures the workpiece 5 is not damaged, extending its service life and effectively preventing displacement of the workpiece 5 during subsequent processing and flipping. Since the positioning element 12 and the clamping element 13 are integrated into the same mounting base 11, when the flipping mechanism 2 drives the mounting base 11 to rotate, the workpiece 5 flips synchronously with it, and the reference position of the workpiece 5 relative to the positioning element 12 remains unchanged. Thus, the workpiece 5 can share the same reference during front and back processing, eliminating the need for secondary clamping and realignment, thereby avoiding cumulative errors introduced by repeated positioning, ensuring the relative positional accuracy between front and back processing elements, and significantly improving the overall processing quality and consistency of the workpiece 5.

[0027] In one embodiment, the clamping member 13 includes a movable member 131 and a linear drive mechanism 132. The movable member 131 is disposed on one side of the positioning member 12 and slidably connected to the mounting base 11. The linear drive mechanism 132 is used to drive the movable member 131 to approach the positioning member 12 and press the workpiece 5 onto the positioning member 12; it is also used to drive the movable member 131 away from the positioning member 12 and release the workpiece 5.

[0028] Since the clamping member 13 adopts a cooperative structure of moving member 131 and linear drive mechanism 132, the linear drive mechanism 132 can directly drive the moving member 131 to reciprocate linear motion in a set direction, so that the moving member 131 applies clamping force to the workpiece 5 when it is close to the positioning member 12 and releases the workpiece 5 when it is far away from the positioning member 12, thereby realizing a fast and smooth switching between the clamping and releasing states.

[0029] In one embodiment, the linear drive mechanism 132 includes a rotary motor 1324, a pressure rod 1322, and an elastic element 1323. The moving member 131 is provided with a first driving surface 1312 and a second driving surface 1313. The pressure rod 1322 has a driving portion that is closer to the positioning member 12 than the first driving surface 1312. The elastic element 1323 is farther from the positioning member 12 than the second driving surface 1313, and the elastic element 1323 is used to apply a spring force towards the positioning member 12 to the moving member 131. The rotary motor 1324... The output end of the motor is fixedly connected to the pressure rod 1322. The rotary motor 1324 is used to drive the pressure rod 1322 to swing downward around the axis of the output end of the rotary motor 1324 so as to abut against the first driving surface 1312 and the moving member 131 to overcome the elastic force of the elastic member 1323 so that the moving member 131 moves away from the positioning member 12. The rotary motor 1324 is also used to drive the pressure rod 1322 to swing upward around the axis of the output end of the rotary motor 1324 so that the moving member 131 moves closer to the positioning member 12 under the action of the elastic force of the elastic member 1323.

[0030] The mounting base 11 has a receiving chamber with a guide surface 1321. A movable component 131 is slidably connected to the guide surface 1321. A guide rod is provided inside the mounting base 11 and passes through the movable component 131. An elastic component 1323 is provided between the side of the movable component 131 away from the positioning component 12 and the mounting base 11. The elastic component 1323 is fixedly installed on the mounting base 11. A clearance hole is provided on the movable component 131 to facilitate the installation of the workpiece. The position where the pressure rod 1322 passes through the movable component 131 allows the movable component 1323 to move away from the positioning component 12 and allows the workpiece to be fitted onto the positioning component 12.

[0031] The elastic element 1323 continuously applies a spring force toward the positioning element 12 to the moving element 131, so that the moving element 131 remains clamped in its natural state with uniform force, protecting the workpiece from damage.

[0032] In one embodiment, the movable member 131 is provided with a V-groove 1311 at one end for contacting the workpiece 5, which can adapt to workpieces 5 of different sizes.

[0033] In one embodiment, a support component 4 is also included. The clamping mechanism 1 is used to clamp and position one end of the workpiece 5. The support component 4 is used to support and release the other end of the workpiece 5. When the working mechanism 3 is processing, the support component 4 supports the other end of the workpiece 5. Before the flipping mechanism 2 flips, the support component 4 releases the other end of the workpiece 5.

[0034] By setting the support component 4 and the clamping mechanism 1 to support and clamp the two ends of the workpiece 5 respectively, the workpiece 5 is in a simply supported state with balanced forces at both ends during processing. This effectively shortens the overhang length of the workpiece 5 in the processing area, significantly improving the bending rigidity and vibration resistance of the workpiece 5 under cutting forces, which is beneficial to ensuring processing accuracy and surface quality. At the same time, before the flipping mechanism 2 is activated, the support component 4 releases the end of the workpiece 5 first, avoiding interference with the flipping motion, so that the clamping mechanism 1 can independently and freely drive the workpiece 5 to complete the rotation. This timing control method of supporting at both ends and releasing at the end before flipping during processing takes into account both the stability requirements of heavy cutting and the motion freedom requirements of multi-faceted flipping, achieving a compatible unity of stable support and flexible flipping.

[0035] In one embodiment, the support component 4 is capable of vertical movement to support and release the other end of the workpiece 5. The support component 4 can be a cylinder 41 and a support member 42. The extension and retraction end of the cylinder 41 is fixedly connected to the support member 42, which is used to contact the other end of the workpiece 5. The end of the support member 42 that contacts the workpiece 5 is set with a first V-groove to distribute pressure and avoid damaging the workpiece. It is compatible with multiple workpieces. The extension and retraction of the cylinder 41 drives the support member 42 to support and release the other end of the workpiece 5. The support component 4 uses a cylinder 41 to drive the support member 42 to make vertical movements. It has a simple structure and a rapid action response. It can extend upward to support the other end of the workpiece 5 during processing and retract downward to release the workpiece 5 before flipping. It not only provides auxiliary support to the end of the workpiece 5, but also avoids interference with the flipping movement in time before flipping.

[0036] In one embodiment, the flipping mechanism 2 includes a rotary drive 21 and a connector 22. The rotary drive 21 is fixedly disposed. The free end of the rotary drive 21 is fixedly connected to the connector 22. The connector 22 is used to connect to the mounting base 11 and drive the mounting base 11 to rotate.

[0037] The rotary drive component 21 is fixedly installed, and its free end is fixedly connected to the mounting base 11 via the connector 22. When the rotary drive component 21 is started, it directly drives the connector 22 and the mounting base 11 to rotate as a whole, thereby driving the clamping mechanism 1 and the workpiece 5 to rotate synchronously. In this structure, the rotary drive component 21 and the mounting base 11 are rigidly connected only through the connector 22. The transmission path is short and there are few intermediate links. The rotational power can be directly and efficiently transmitted to the mounting base 11 without transmission gaps or lag, ensuring the accuracy of the rotation angle and the high efficiency of the response.

[0038] In one embodiment, the flipping mechanism 2 further includes a moving component 23, which is used to drive the rotating drive 21 and the connecting member 22 connected thereto to move closer to or away from the mounting base 11, so that the connecting member 22 and the mounting base 11 can be connected and disconnected.

[0039] The flipping mechanism 2 is further provided with a moving component 23, which can drive the rotating drive component 21 and the connecting component 22 to move as a whole, so that the connecting component 22 and the mounting base 11 can have two working states: connected and disconnected.

[0040] It also includes a positioning seat, which is fixedly installed. A mounting seat 11 is rotatably connected to the positioning seat. The positioning seat is rotatably connected to the mounting seat 11 via a rotating shaft, which is also connected to a connecting block. The connecting block is used to connect with the connecting member 22. When flipping or processing is required, the moving component 23 drives the connecting member 22 to move closer to the mounting seat 11 and form a fixed connection with the mounting seat 11, thereby establishing a power transmission path. When the workpiece 5 is in a non-processing state or does not need to be flipped, the moving component 23 drives the connecting member 22 to move away from the mounting seat 11 and completely disengage from the mounting seat 11, making the mounting seat 11 and the clamping mechanism 1 physically independent of the flipping mechanism 2. The connecting member 22 and the mounting seat 11 are separated in the non-flipping state, providing the mounting seat 11 with a larger space for movement, facilitating the loading and unloading of the workpiece 5 and other auxiliary operations, while avoiding the problem of increased inertial load caused by the long-term rigid connection between the flipping mechanism 2 and the mounting seat 11. By controlling the access and disengagement of the moving component 23, the clamping and positioning function and the flipping drive function can work together when needed and be decoupled when not needed, making the overall structure more flexible and reliable, especially suitable for automated production scenarios with multiple workstations or frequent start-stop operations.

[0041] In one specific embodiment, the moving component 23 includes a support base 231, a first motor 232, a first conveyor belt assembly 233, a screw, and a sliding member 234. The first motor 232 is fixed to one end of the support base 231. The output shaft of the first motor 232 is driven and connected to the screw via the first conveyor belt assembly 233. The sliding member 234 is threadedly connected to the screw and slidably connected within the support base 231. A rotary drive component 21 is mounted on the sliding member 234. The rotary drive component 21 includes a second motor, a second conveyor belt assembly, and a connecting member 22. The output shaft of the second motor is driven and connected to the connecting member 22 via the second conveyor belt assembly. The connecting member 22 is used to connect to the mounting base 11. Through the above-mentioned two-stage independent drive design, linear movement and rotational movement are independently controlled by the first motor 232 and the second motor, respectively, which facilitates the optimization of control parameters. At the same time, the conveyor belt drive has a buffering and vibration absorption effect, making the movement smooth. Furthermore, the conveyor belt assembly has a simple structure, low noise, and is easy to replace, effectively reducing maintenance and manufacturing costs.

[0042] In one embodiment, the working mechanism 3 is configured as three, namely a drilling working mechanism 31, a tapping working mechanism 32 and a screw tightening working mechanism 33, and the three working mechanisms 3 are located on a single workbench, eliminating the need for cross-equipment transfer and reducing the loss of workpiece 5 during handling. When the workpiece 5 is transferred between the drilling working mechanism 31, the tapping working mechanism 32 and the screw tightening working mechanism 33, it is handled manually.

[0043] The working mechanism 3 includes a mounting frame, a transmission component, a drive component, a platform, a lifting component, and a working tool. The mounting frame is fixedly mounted on the workbench, the drive component is fixedly mounted on the mounting frame, the output end of the drive component is fixedly connected to the input end of the transmission component, the output end of the transmission component is fixedly connected to the platform, the lifting component is fixedly mounted on the platform, and the output end of the lifting component is fixedly connected to the working tool. The working tool is used to process the workpiece 5. The drive component drives the platform to move horizontally to a set position through the transmission component, and the lifting component drives the working tool to move vertically to complete the processing operation.

[0044] The tools used can be drill bits, taps, or screwdriver bits.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
