Description

Technical Field

[0001] This invention relates to the field of workpiece processing technology, specifically to a device for treating burrs on stamped parts produced in automobile manufacturing. Background Technology

[0002] In the automotive manufacturing industry, stamped parts are key components in automobile production, and their quality directly affects the overall performance, appearance, and service life of the vehicle. However, during the production process of stamped parts, due to factors such as die wear and limitations of the stamping process, burrs and rough edges often form on the edges and ends of the stamped parts. These burrs and rough edges not only affect the assembly accuracy of the stamped parts, leading to loose fits between parts and causing problems such as abnormal noise and looseness, but may also scratch other parts or personnel during vehicle use, posing significant safety hazards. Therefore, burr removal for stamped parts in automobile production is an indispensable and important step in the automobile production process. Currently, there are some burr removal devices for stamped parts in automobile production on the market. These existing technologies meet the basic needs of automobile manufacturers to a certain extent, but they also have many obvious shortcomings:

[0003] Defects in positioning and clamping: Existing burr removal devices are inadequate in terms of workpiece positioning and clamping. Some devices only use a simple single-stage limiting method. During the workpiece conveying process, it is difficult to ensure that the workpiece is in an accurate position before entering the grinding area. For example, if the workpiece is positioned by relying on a single limiting block or limiting rod, it cannot be effectively corrected in time when the workpiece deviates or shakes slightly during the conveying process, resulting in inaccurate subsequent grinding position and affecting the quality of burr removal.

[0004] Defects in grinding effect: Existing burr removal devices also have many problems in grinding effect. On the one hand, the grinding method is relatively simple, usually only the end or edge of the workpiece can be processed separately, and the end and edge cannot be ground at the same time. This means that when processing a stamped part, it is necessary to go through multiple clamping and different processes to complete the burr treatment of the end and edge. This not only increases the production cycle and reduces production efficiency, but also the multiple clamping will lead to the accumulation of positioning errors, resulting in a decline in the overall processing quality of the workpiece. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for processing burrs on stamped parts used in automobile production, which solves the technical problems mentioned in the background section.

An arc-shaped rod is fixedly connected to the outer wall of the movable seat, and the arc-shaped rod is slidably installed on the rotating plate. A damping spring sleeved on the arc-shaped rod is provided between the movable seat and the rotating plate.

[0009] As a further preferred embodiment of this technical solution, an adjustment motor is fixedly installed on the outer end of the mounting frame, a gear is fixedly connected to the output end of the adjustment motor, and a rack is meshed on both sides of the gear. The rack is slidably installed on the mounting frame, and the two racks are symmetrically centered. A clamping block is fixedly installed at the end of the rack.

[0010] As a further preferred embodiment of this technical solution, the conveying assembly includes a horizontal plate fixedly installed on a support plate, with a first material box and a second material box fixedly installed on both sides of the horizontal plate, the first material box being used for storing workpieces, and the second material box being used for storing workpieces after burr removal.

[0011] As a further preferred embodiment of this technical solution, rotating shafts are rotatably connected to both sides of the horizontal plate, and sprockets are fixedly installed at the ends of the rotating shafts. The two sprockets are driven by a chain. A discharge port is provided on the side of the first material box near the chain. Conveying seats are provided at equal intervals on the outer wall of the chain. The surface of the conveying seat has a deep V-shaped structure, and the position of the conveying seat corresponds to the discharge port of the first material box. A drive motor is fixedly installed on the outer side of the horizontal plate, and the output end of the drive motor is fixedly connected to one of the rotating shafts.

[0012] As a further preferred embodiment of this technical solution, a lifting seat is fixedly installed on the surface of the workbench, a cylinder is fixedly installed at the bottom of the lifting seat, the output end of the cylinder is fixedly connected to the lifting seat, a support seat is fixedly installed on the top of the lifting seat, and an adjusting seat is slidably connected to the top of the support seat via a slide rail. A set of first limit wheels is provided on both sides of the top of the adjusting seat, and two first limit wheels are symmetrically arranged in each set.

[0013] As a further preferred embodiment of this technical solution, an inclined block is fixedly installed on the surface of the lifting seat, and a positioning shaft is fixedly installed on the surface of the positioning seat. A Z-shaped frame is rotatably connected to the positioning shaft via a torsion spring, and a moving wheel that slides and adapts to the inclined block is provided at the bottom of the Z-shaped frame.

[0014] As a further preferred embodiment of this technical solution, a connecting frame is fixedly connected to the outer wall of the adjusting seat, a sliding groove is provided on the surface of the connecting frame, and a sliding shaft is provided on the top of the Z-shaped frame, and the sliding shaft is slidably installed in the sliding groove.

[0015] Compared with existing technologies, it has the following advantages:

[0016] Precise positioning and stable clamping ensure processing quality.

[0017] Multi-level limiting positioning: The first limiting wheel and the second limiting wheel in the device cooperate with each other. During the workpiece conveying process, the first limiting wheel not only drives the workpiece to move upward, but also tilts it to the side of the second limiting wheel to achieve preliminary positioning. This multi-level limiting method can ensure that the workpiece is in a relatively accurate position before entering the grinding area, laying the foundation for subsequent precise processing.

[0018] Dynamic clamping adjustment: Adjusting the motor drives the gear to rotate, which in turn drives two centrally symmetrical racks to slide, causing the two clamping blocks to move closer or further apart. This design can be flexibly adjusted according to workpieces of different sizes and shapes to achieve a firm clamping of the workpiece. During the processing, stable clamping can effectively prevent the workpiece from shifting or shaking due to the grinding force, ensuring the accuracy and consistency of grinding, and greatly improving the quality of burr removal.

[0019] Thorough polishing to improve processing results

[0020] Simultaneous processing of ends and edges: The first grinding wheel is responsible for grinding the end surface of the workpiece, while the second grinding wheel focuses on cleaning the burrs on the edge of the workpiece. The two grinding wheels work at the same time, which can complete the burr treatment of the end and edge of the workpiece in one go. This avoids the tedious operation of multiple clamping and different processes required in the traditional processing method, improves processing efficiency, and reduces the positioning error that may be caused by multiple clamping, thus ensuring the overall processing quality of the workpiece.

[0021] 360° full-range polishing: The servo motor drives the rotating plate and the first and second polishing wheels mounted on it to rotate around the workpiece axis. This rotary polishing method allows the polishing wheels to fully cover the end of the workpiece from all angles, ensuring that every part of the end is fully polished. This effectively removes burrs and rough edges that may be missed by traditional fixed polishing methods, making the end of the workpiece smoother and flatter, and improving the appearance quality and performance of the product.

[0022] Adaptive grinding, suitable for various workpieces

[0023] Elastic contact grinding: A damping spring is set between the movable seat and the rotating plate and sleeved on the arc-shaped rod. Under the elastic force of the damping spring, the second grinding wheel can always maintain contact with the edge of the workpiece. This adaptive design allows the second grinding wheel to automatically adjust its position and pressure according to the shape and size of the workpiece edge. Whether the workpiece edge is regular or irregular, it can achieve uniform and effective grinding, which improves the versatility and adaptability of the device.

[0024] Adaptable to workpieces of different thicknesses: Since the second grinding wheel is connected to the rotating plate through a movable seat and a damping spring, when processing workpieces of different thicknesses, the second grinding wheel can automatically adjust the contact depth with the edge of the workpiece under the action of the damping spring, ensuring that a good grinding effect is always maintained. This adaptive capability enables the device to process automotive stamping parts of various specifications, reducing the time and cost consumption caused by changing equipment of different specifications or adjusting complex parameters.

[0034] The technical solutions in 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.

[0035] Example 1: Combining Figures 1-8 As shown, the present invention provides a technical solution: a burr removal device for stamped parts in automobile production. It is a precision device designed to meet the needs of burr removal on the edges of stamped parts in automobile manufacturing. The device mainly consists of a workbench 1 and a workpiece 4 that needs to be burred, forming the core processing scene. A support plate 2 is stably installed on the top of the workbench 1. A conveying component 3 is cleverly set at the front end of the support plate 2. A burr removal component 5 for removing burrs from the workpiece 4 is also carefully arranged on the support plate 2. The conveying component 3 undertakes the key task of accurately conveying the workpiece 4 to the burr removal component 5, ensuring that the workpiece can smoothly enter the processing flow.

[0036] The burr removal component 5 is the core functional module of the entire device. It is ingeniously designed and fully functional. It includes a fixed plate 51 fixedly installed on the support plate 2. A set of second limiting wheels 52 are provided on both sides of the bottom end of the fixed plate 51. There are two symmetrically arranged second limiting wheels 52 in each set. This layout provides a basic guarantee for the stable positioning of the workpiece 4 during the processing. A vertical plate 53 is fixedly installed on one side of the bottom of the fixed plate 51. A mounting frame 54 is fixedly installed at the bottom end of the vertical plate 53. The mounting frame 54 serves as the support frame of the entire processing component and bears multiple key components.

[0037] A servo motor 55 is fixedly installed on the side of the mounting frame 54 near the conveying component 3. The servo motor 55 is precisely set along the axis of the workpiece 4. This design ensures that subsequent processing actions can be carried out in an orderly manner around the axis of the workpiece. A rotating plate 56 is fixedly connected to the output end of the servo motor 55. The rotating plate 56 serves as a key hub connecting multiple grinding components. Mounting bases 57 are fixedly installed on the upper and lower ends of its surface. A first grinding motor 58 is fixedly installed on one side of the mounting base 57. A first grinding wheel 59 is fixedly installed at the output end of the first grinding motor 58. The first grinding wheel 59 is responsible for grinding the end surface of the workpiece.

[0038] The rotating plate 56 is rotatably connected to two movable seats 510. A second grinding motor 511 is fixedly installed on one side of the movable seat 510. A second grinding wheel 512 is fixedly connected to the output end of the second grinding motor 511. The second grinding wheel 512 focuses on grinding and removing burrs from the edge of the workpiece. An arc-shaped rod 513 is fixedly connected to the outer wall of the movable seat 510, and the arc-shaped rod 513 is slidably installed on the rotating plate 56. A damping spring 514 is provided between the movable seat 510 and the rotating plate 56 and sleeved on the arc-shaped rod 513. Under the elastic force of the damping spring 514, the second grinding wheel 512 can always maintain close contact with the edge of the workpiece, ensuring that the grinding effect is uniform and stable.

[0039] An adjusting motor 515 is fixedly installed on the outer end of the mounting frame 54. The adjusting motor 515 serves as the power source for controlling the clamping action. A gear 516 is fixedly connected to its output end. Gear racks 517 are meshed on both sides of the gear 516. The gear racks 517 are slidably installed on the mounting frame 54, and the two gear racks 517 are centrally symmetrically arranged. This design ensures that the two gear racks 517 can move synchronously and in opposite directions. A clamping block 518 is fixedly installed at the end of the gear rack 517. Driven by the adjusting motor 515, the two clamping blocks 518 can move closer or further away from each other, thereby achieving precise clamping and release of the workpiece.

[0040] In the embodiments of the present invention, the entire burr removal process is smooth and efficient. First, by utilizing the unique design of the first limiting wheel 313, while driving the workpiece 4 to move upward, the workpiece can be tilted to the side of the second limiting wheel 52, so that the end of the workpiece 4 makes precise contact with the surface of the first grinding wheel 59, and the edge of the workpiece 4 also fits tightly with the surface of the second grinding wheel 512. Furthermore, the first limiting wheel 313 and the second limiting wheel 52 cooperate with each other to perform preliminary clamping and positioning of the workpiece 4, ensuring the basic stability of the workpiece during the processing.

[0041] Subsequently, the adjusting motor 515 is turned on, which drives the gear 516 to rotate synchronously. Since the gear 516 is meshed with the two racks 517, the rotation of the gear 516 will drive the two racks 517 to slide along the mounting bracket 54, and the two racks 517 will move closer to each other. The movement of the racks 517 will further drive the two clamping blocks 518 to move closer to each other, so that the two clamping blocks 518 can firmly clamp and position the workpiece 4, providing stable support for subsequent grinding operations.

[0042] Next, the first grinding motor 58 and the second grinding motor 511 are turned on. The first grinding motor 58 drives the first grinding wheel 59 to rotate at high speed, and the second grinding motor 511 drives the second grinding wheel 512 to rotate synchronously. Under the high-speed rotation of the first grinding wheel 59 and the second grinding wheel 512, the end surface and edge of the workpiece 4 are thoroughly and meticulously ground to remove burrs.

[0043] Finally, the servo motor 55 drives the rotating plate 56 to rotate. Since the first grinding wheel 59 and the second grinding wheel 512 are both mounted on the rotating plate 56, they will rotate together with the rotating plate 56 around the axis of the workpiece 4. This rotation method allows the first grinding wheel 59 and the second grinding wheel 512 to perform comprehensive burr treatment on the end of the workpiece 4 from different angles, ensuring that every part of the end of the workpiece is fully ground, thereby achieving the ideal burr treatment effect and providing a strong guarantee for the high-quality production of automotive stamping parts.

[0044] Example 2: Combination Figure 2 , Figure 3As shown, based on Embodiment 1, a horizontal plate 31 is fixedly installed on the front surface of the conveying assembly 3 by bolts. The horizontal plate 31 serves as the basic support component of the entire conveying and positioning structure, possessing high strength and stability. A first material box 32 and a second material box 33 are respectively installed on both sides of the horizontal plate 31 by welding or bolting. The first material box 32 is specifically used for storing workpieces 4. Its internal structure is rationally designed to accommodate multiple workpieces 4 in an orderly manner, facilitating subsequent individual removal operations. The second material box 33 is used to store workpieces 4 after burr removal. Its size and shape are designed according to the specifications of the workpieces 4 to ensure proper placement of the processed workpieces 4.

[0045] The horizontal plate 31 is rotatably connected to the two sides by bearings with rotating shafts 34. The ends of the rotating shafts 34 are fixedly installed with sprockets by key connection, and the two sprockets are connected by a chain 36. The chain 36 is made of high-strength and wear-resistant material to ensure that it will not break or wear excessively during long-term operation. The first material box 32 is provided with a discharge port on the side near the chain 36. The size and shape of the discharge port are precisely calculated to match the size of the workpiece 4, ensuring that the workpiece 4 can be smoothly taken out of the first material box 32. The outer wall of the chain 36 is provided with conveyor seats 37 at equal intervals. The surface of the conveyor seats 37 has a deep V-shaped structure. This unique structural design allows the conveyor seats 37 to accurately take out the workpieces 4 one by one when they move to the discharge port of the first material box 32. Moreover, the positions of the conveyor seats 37 and the discharge port of the first material box 32 correspond to each other, ensuring the accuracy and stability of material picking.

[0046] A drive motor 35 is fixedly installed on the outer side of the horizontal plate 31. The drive motor 35 is selected as a model with stable performance and appropriate power to meet the power requirements of the entire conveying system. The output end of the drive motor 35 is fixedly connected to one of the rotating shafts 34 through a coupling. In actual operation, the workpieces 4 that need to be deburred are placed into the first material box 32 in sequence. By turning on the drive motor 35, the drive motor 35 drives the rotating shaft 34 connected to it to rotate. This rotating shaft 34 is driven by a sprocket and a chain 36, thereby driving the other rotating shaft 34 and the conveyor seat 37 on the chain 36 to move and convey. The conveyor seat 37 moves upwards. When it reaches the outlet of the first material box 32, its deep V-shaped surface cleverly catches and removes the workpieces 4 sequentially. As the chain 36 continues to drive, the conveyor seat 37 gradually moves upwards with the workpieces 4. When the workpieces 4 reach the deburring component 5, the drive motor 35 is turned off. At this time, the deburring component 5 deburrs the workpieces 4. After deburring, the drive motor 35 is turned on again, and the conveyor seat 37 continues to drive, conveying the deburred workpieces 4 to the second material box 33 for collection.

[0047] A lifting seat 310 is bolted to the surface of the worktable 1. As a crucial component of the entire lifting and positioning mechanism, the lifting seat 310 possesses sufficient load-bearing capacity. A cylinder 39 is fixedly mounted at the bottom of the lifting seat 310. The cylinder 39 is selected for its high precision and fast response speed to ensure accurate control of the lifting height of the lifting seat 310. The output end of the cylinder 39 is fixedly connected to the lifting seat 310. A support seat 311 is bolted to the top of the lifting seat 310. The support seat 311 provides stable support for the adjusting seat 312. The top of the support seat 311 is slidably connected to the adjusting seat 312 via a slide rail. The slide rail design allows the adjusting seat 312 to slide smoothly on the support seat 311, reducing friction and... To prevent wear, a set of first limiting wheels 313 are provided on both sides of the top of the adjusting seat 312, and two first limiting wheels 313 are symmetrically arranged in each set. The first limiting wheels 313 are made of wear-resistant and moderately hard material to ensure that they will not damage the workpiece 4 when in contact with it, and at the same time provide a stable limiting function. When the workpiece 4 moves to the position directly above the first limiting wheel 313, the piston rod of the cylinder 39 is extended by opening the cylinder 39, which drives the lifting seat 310, the support seat 311, the adjusting seat 312, and the first limiting wheel 313 to move upward, so that the first limiting wheel 313 drives the workpiece 4 to move synchronously to the side of the burr treatment component 5, and the burr treatment component 5 is used to treat the burr of the workpiece 4.

[0048] An inclined block 314 is fixedly mounted on the surface of the lifting seat 310 by welding or bolting. The inclination angle of the inclined block 314 is precisely calculated to ensure good fit with subsequent components. A positioning shaft 315 is fixedly mounted on the surface of the positioning seat 38 by bolts. The positioning shaft 315 provides a stable axis for the rotation of the Z-shaped frame 316. The Z-shaped frame 316 is rotatably connected to the positioning shaft 315 by a torsion spring. The elastic coefficient of the torsion spring is appropriately selected so that the Z-shaped frame 316 can rotate when subjected to external force and return to its initial position after the external force is removed. The bottom of the frame 316 is provided with a movable wheel 317 that is slidably adapted to the tilting block 314. The movable wheel 317 can reduce the friction between the Z-shaped frame 316 and the tilting block 314, making the rotation smoother. Under the elastic force of the torsion spring, the Z-shaped frame 316 is pushed to rotate, so that the movable wheel 317 always keeps in contact with the tilting block 314. The outer wall of the adjusting seat 312 is fixedly connected to the connecting frame 318 by welding or bolting. The surface of the connecting frame 318 is provided with a sliding groove 319, and the top of the Z-shaped frame 316 is provided with a sliding shaft, which is slidably installed in the sliding groove 319.

[0049] When the cylinder 39 is activated, it drives the lifting seat 310 to move upward. The lifting seat 310 can drive the tilting block 314 to move synchronously. When the tilting block 314 moves upward, its tilting surface contacts the moving wheel 317 and generates a force, pushing the Z-shaped frame 316 to rotate on the positioning shaft 315. During the rotation of the Z-shaped frame 316, the sliding shaft at its top slides in the sliding groove 319 of the connecting frame 318. This allows the Z-shaped frame 316, together with the sliding shaft, connecting frame 318, and sliding groove 319, to push the adjusting seat 312 and the first limiting wheel 313 to move towards the burr processing component 5. In this way, the first limiting wheel 313 can drive the workpiece 4 to move towards the second limiting wheel 52, so that the end of the workpiece 4 moves to the position of the burr processing component 5. The first limiting wheel 313 and the second limiting wheel 52 are used to perform preliminary clamping and positioning of the workpiece 4, providing a stable workpiece position guarantee for subsequent burr processing.

[0050] In an embodiment of the present invention, the workpieces 4 that need to be deburred are sequentially placed into the first material box 32. The drive motor 35 is turned on to drive the rotating shaft 34 to rotate. The rotating shaft 34 is driven by the sprocket and the chain 36, thereby driving the conveyor seat 37 to move. The conveyor seat 37 moves from bottom to top. When the conveyor seat 37 moves to the outlet of the first material box 32, the surface of the conveyor seat 37 has a deep V-shaped structure, and its unique shape can accurately match the shape of the workpiece 4, so the workpiece 4 is taken out sequentially. As the chain 36 continues to drive, the conveyor seat 37 carries the workpiece 4 to gradually approach the deburring component 5. When the workpiece 4 moves to the position of the deburring component 5, the drive motor 35 is turned off. At this time, the workpiece 4 is in a waiting state. The deburring component 5 is used to deburr the workpiece 4. After the processing is completed, the drive motor 35 is turned on again, and the conveyor seat 37 continues to drive, conveying the deburred workpiece 4 to the second material box 33 for collection and processing.

[0051] When the cylinder 39 is activated, it moves the lifting seat 310 upward. The lifting seat 310 then moves the tilting block 314 synchronously. During the upward movement, the tilting block 314's inclined surface contacts the moving wheel 317 at the bottom of the Z-shaped frame 316. Due to the tilted design of the tilting block 314, a horizontal force is generated on the moving wheel 317. This force pushes the Z-shaped frame 316 to rotate on the positioning shaft 315. During this rotation, the sliding shaft at the top of the Z-shaped frame 316 slides within the sliding groove 319 of the connecting frame 318. The sliding groove 319 guides the movement of the sliding shaft, allowing the Z-shaped frame 316 to rotate smoothly. The force is converted into a horizontal pushing force on the adjusting seat 312, which enables the Z-shaped frame 316, in conjunction with the sliding shaft, connecting frame 318, and sliding groove 319, to push the adjusting seat 312 and the first limiting wheel 313 toward the burr processing component 5. During the movement, the first limiting wheel 313 drives the workpiece 4 toward the second limiting wheel 52, so that the end of the workpiece 4 moves to the position of the burr processing component 5. At this time, the first limiting wheel 313 and the second limiting wheel 52 perform preliminary clamping and positioning of the workpiece 4 from both sides, ensuring that the position of the workpiece 4 is stable during the burr processing process and will not shake or shift, thereby improving the quality and accuracy of the burr processing.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
