Description

Technical Field

[0001] The invention relates to the technical field of workpiece processing, in particular to a burr processing device for stamping parts in automobile production. Background Art

[0002] In the automotive manufacturing industry, stamping parts are key components in automobile production, and their quality directly affects the overall performance, appearance quality and service life of the automobile. However, in the production process of stamping parts, due to factors such as mold wear and the limitation of stamping process, burrs and burrs often appear on the edges and ends of stamping parts. These burrs and burrs not only affect the assembly accuracy of stamping parts, resulting in loose fit between parts, abnormal noise, looseness and other problems, but may also scratch other parts or personnel during the use of the car, posing a major safety hazard. Therefore, burr treatment of automobile stamping parts is an indispensable and important part of the automobile production process. At present, there are already some automobile stamping parts burr treatment devices on the market. These existing technologies have met the basic needs of automobile manufacturers to a certain extent, but they also have many obvious defects:

[0003] Defects in positioning and clamping: Existing burr processing devices have deficiencies in workpiece positioning and clamping. Some devices only use a simple single-stage limit method. During the workpiece transportation process, it is difficult to ensure that the workpiece is in the correct position before entering the grinding area. For example, if the workpiece is positioned only by a single limit block or limit rod, when the workpiece deviates or shakes slightly during transportation, it cannot be effectively corrected in time, resulting in inaccurate subsequent grinding position and affecting the quality of burr treatment.

[0004] Defects in grinding effect: The existing burr processing device also has many problems in grinding effect. On the one hand, the grinding method is relatively single, and usually only the end or edge of the workpiece can be processed separately, and the simultaneous grinding of the end and edge cannot be achieved. This means that when processing a stamping part, it is necessary to go through multiple clamping and different processes to complete the burr processing of the end and edge, which not only increases the production cycle and reduces production efficiency, but also multiple clamping will bring about the accumulation of positioning errors, resulting in a decrease in the overall processing quality of the workpiece.

[0015] Compared with the existing technology, it has the following beneficial effects:

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

[0017] Multi-level limit positioning: The first limit wheel and the second limit wheel in the device cooperate with each other. During the workpiece conveying process, the first limit wheel not only drives the workpiece to move upward, but also makes it tilt toward the side of the second limit wheel to achieve preliminary positioning. This multi-level limit 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: The motor drives the gear to rotate, which in turn drives the two centrally symmetrical gear rods to slide, so that the two clamping blocks move closer or further away from each other. 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, the stable clamping can effectively prevent the workpiece from displacement or shaking due to the grinding force, ensuring the accuracy and consistency of the grinding and greatly improving the quality of the burr treatment.

[0019] All-round polishing to improve processing effect

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

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

[0022] Adaptive grinding to suit various workpieces

[0023] Elastic fit grinding: A damping spring sleeved on an arc-shaped rod is provided between the movable seat and the rotating plate. Under the elastic force of the damping spring, the second grinding wheel can always maintain fit 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 edge of a workpiece is regular or irregular in shape, it can achieve uniform and effective grinding, improving the versatility and adaptability of the device.

[0024] Adaptability 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 ability enables the device to process various specifications of automotive stamping parts, reducing the time and cost consumption caused by replacing equipment of different specifications or adjusting complex parameters.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1: Combination Figures 1-8 As shown, the present invention provides a technical solution: a burr processing device for automobile production stamping parts, which is a precision equipment designed for the need to clean burrs on the edges of stamping parts in the automobile manufacturing process. The device mainly consists of a workbench 1 and a workpiece 4 that needs to be burred, forming a core processing scene. A support plate 2 is firmly installed on the top of the workbench 1, and a conveying component 3 is cleverly arranged at the front end of the support plate 2. A burr processing component 5 for burring 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 side of the burr processing component 5 to ensure that the workpiece can smoothly enter the processing process;

[0036] The burr processing assembly 5 is the core functional module of the entire device. It is exquisitely designed and fully functional. It includes a fixed plate 51 fixedly mounted 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, and each set of second limiting wheels 52 is symmetrically provided with two. This layout provides a basic guarantee for the stable positioning of the workpiece 4 during the processing process. A vertical plate 53 is fixedly mounted on one side of the bottom of the fixed plate 51. A mounting frame 54 is fixedly mounted on the bottom end of the vertical plate 53. The mounting frame 54 serves as the support frame of the entire processing assembly and carries multiple key components.

[0037] A servo motor 55 is fixedly mounted on the side of the mounting frame 54 close to the conveying assembly 3. The servo motor 55 is precisely set with respect to 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. The output end of the servo motor 55 is fixedly connected to a rotating plate 56. The rotating plate 56 serves as a key hub for connecting multiple grinding components. A mounting seat 57 is fixedly mounted on the upper and lower ends of the surface of the rotating plate 56. A first grinding motor 58 is fixedly mounted on one side of the mounting seat 57. A first grinding wheel 59 is fixedly mounted on the output end of the first grinding motor 58. The first grinding wheel 59 is responsible for grinding the surface of the end of the workpiece.

[0038] The movable seats 510 are rotatably connected to both sides of the rotating plate 56. 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 is used to grind and remove burrs on the edge of the workpiece. An arc rod 513 is fixedly connected to the outer wall of the movable seat 510, and the arc rod 513 is slidably mounted on the rotating plate 56. A damping spring 514 is provided between the movable seat 510 and the rotating plate 56 and is sleeved on the arc 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 a uniform and stable grinding effect.

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

[0040] In the embodiment of the present invention, the entire burr processing 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 and moved toward the side of the second limiting wheel 52, so that the end of the workpiece 4 is precisely in contact with the surface of the first grinding wheel 59, and the edge of the workpiece 4 is also closely fitted with the surface of the second grinding wheel 512. In addition, 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 process;

[0041] Subsequently, the adjustment motor 515 is turned on, and the adjustment motor 515 drives the gear 516 to rotate synchronously. Since the gear 516 is meshed with the two gear rods 517, the rotation of the gear 516 drives the two gear rods 517 to slide along the mounting frame 54, and the two gear rods 517 approach each other. The movement of the gear rods 517 further drives the two clamping blocks 518 to approach each other, and finally the two clamping blocks 518 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 the edge of the workpiece 4 are comprehensively and carefully ground and deburred.

[0043] Finally, the rotating plate 56 is driven to rotate by the servo motor 55. Since the first grinding wheel 59 and the second grinding wheel 512 are both installed on the rotating plate 56, they will rotate with the rotating plate 56 around the axis of the workpiece 4. This rotation method enables 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 can be fully polished, thereby achieving an ideal burr treatment effect, providing a strong guarantee for the high-quality production of automotive stamping parts.

[0044] Example 2: Combination Figure 2 、 Figure 3As shown, on the basis of the first embodiment, a transverse plate 31 is fixedly installed on the front surface of the conveying component 3 by bolts. The transverse plate 31 serves as the basic supporting component of the entire conveying and positioning structure and has high strength and stability. A first material box 32 and a second material box 33 are respectively installed on both sides of the transverse plate 31 by welding or bolting. The first material box 32 is specially used for storing workpieces 4. Its internal structure is reasonably designed and can accommodate multiple workpieces 4 in an orderly manner, which is convenient for subsequent one-by-one removal operations; the second material box 33 is used to store the workpieces 4 after burr processing. Its size and shape are designed according to the specifications of the workpiece 4 to ensure that the processed workpieces 4 can be properly placed;

[0045] The two sides of the cross plate 31 are rotatably connected to the rotating shaft 34 by bearings, and the ends of the rotating shaft 34 are fixedly installed with sprockets by key connections, 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. A discharge port is provided on the side of the first material box 32 near the chain 36. The size and shape of the discharge port are accurately 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. Conveying seats 37 are provided at equal distances on the outer wall of the chain 36. The surface of the conveying seat 37 has a deep V-shaped structure. This unique structural design enables the conveying seat 37 to accurately take out the workpiece 4 in sequence when it moves to the discharge port of the first material box 32. Moreover, the position of the conveying seat 37 corresponds to the discharge port of the first material box 32, which ensures the accuracy and stability of material removal.

[0046] A drive motor 35 is fixedly installed on the outside of the cross plate 31. The drive motor 35 is selected from 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 processed for burrs are placed in 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. The rotating shaft 34 is driven by the sprocket and the chain 36, thereby driving the other rotating shaft 34 and the conveying seat 37 on the chain 36 to transmit the conveying. The seat 37 is driven from bottom to top. When the conveying seat 37 moves to the discharge port of the first material box 32, due to the deep V-shaped structure of the surface of the conveying seat 37, it can cleverly clamp the workpiece 4 and take it out in sequence. As the chain 36 continues to drive, the conveying seat 37 gradually moves upward with the workpiece 4. When the workpiece 4 moves to the position of the burr processing component 5, the drive motor 35 is turned off. At this time, the burr processing component 5 is used to process the burrs of the workpiece 4. After the processing is completed, the drive motor 35 is turned on again. The conveying seat 37 continues to drive and transports the workpiece 4 with the burr processed to the second material box 33 for collection and processing.

[0047] The surface of the workbench 1 is fixed with a lifting seat 310 by bolts. The lifting seat 310 is an important component of the entire lifting and positioning mechanism and has sufficient bearing capacity. The bottom end of the lifting seat 310 is fixedly installed with a cylinder 39. The cylinder 39 is a model with high precision and fast response speed to ensure that the lifting height of the lifting seat 310 can be accurately controlled. The output end of the cylinder 39 is fixedly connected to the lifting seat 310. The top of the lifting seat 310 is fixed with a support seat 311 by bolts. The support seat 311 provides stable support for the adjustment seat 312. The top of the support seat 311 is slidably connected to the adjustment seat 312 through a slide rail. The design of the slide rail enables the adjustment seat 312 to slide smoothly on the support seat 311, reducing friction and Wear, a group of first limiting wheels 313 are provided on both sides of the top of the adjusting seat 312, and each group of first limiting wheels 313 is symmetrically provided with two, and the material of the first limiting wheels 313 is selected from wear-resistant materials with moderate hardness to ensure that the workpiece 4 will not be damaged when in contact with the workpiece 4, and at the same time can provide a stable limiting effect. When the workpiece 4 moves to the position just above the first limiting wheel 313, by opening the cylinder 39, the piston rod of the cylinder 39 extends, driving the lifting seat 310, the supporting 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 processing component 5, and the burr processing component 5 is used to process the burrs of the workpiece 4;

[0048] The lifting seat 310 is fixed with a tilting block 314 on the surface by welding or bolting. The tilting angle of the tilting block 314 is precisely calculated to ensure that it can cooperate well with subsequent components. The positioning seat 38 is fixed with a positioning shaft 315 on the surface by bolts. The positioning shaft 315 provides a stable axis for the rotation of the Z-shaped frame 316. The positioning shaft 315 is rotatably connected to the Z-shaped frame 316 through 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 can return to its initial position after the external force disappears. The bottom end of the frame 316 is provided with a moving wheel 317 that is slidably adapted to the tilting block 314. The moving 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 moving wheel 317 always keeps in contact with the tilting block 314. The outer wall of the adjustment 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 slide groove 319, and a sliding shaft is provided on the top of the Z-shaped frame 316, and the sliding shaft is slidably installed in the slide groove 319.

[0049] When the cylinder 39 is turned on to drive 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 inclined 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, so that the Z-shaped frame 316 cooperates with the sliding shaft, the connecting frame 318, and the sliding groove 319 to push the adjusting seat 312 and the first limiting wheel 313 to move toward the side of the burr processing component 5. In this way, the first limiting wheel 313 can drive the workpiece 4 to move toward the side of the second limiting wheel 52, so that the end of the workpiece 4 moves to the position of the burr processing component 5, and 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] The conveyor 37 is driven by the sprocket and the chain 36 to drive the conveyor 37 to move upward. When the conveyor 37 moves to the discharge port of the first material box 32, the conveyor 37 is driven by the sprocket and the chain 36 to drive the conveyor 37 to move upward. When the conveyor 37 moves to the discharge port of the first material box 32, the conveyor 37 has a deep V-shaped surface and its unique shape can accurately match the shape of the workpiece 4, so that the workpiece 4 can be taken out in turn. With the continuous transmission of the chain 36, the conveyor 37 brings the workpiece 4 closer to the burr processing component 5. When the workpiece 4 moves to the position of the burr processing component 5, the drive motor 35 is turned off. At this time, the workpiece 4 is in a waiting state. The burr processing component 5 is used to process the workpiece 4. After the processing is completed, the drive motor 35 is turned on again. The conveyor 37 continues to transmit and the workpiece 4 with the burr processed is transported to the second material box 33 for collection and processing.

[0051] When the cylinder 39 is turned on to drive the lifting seat 310 to move upward, the lifting seat 310 can drive the tilting block 314 to move synchronously. During the rising process, the tilting block 314 contacts the moving wheel 317 at the bottom end of the Z-shaped frame 316. Due to the tilting design of the tilting block 314, a horizontal component force is generated on the moving wheel 317. This component force pushes 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. The sliding groove 319 guides the movement of the sliding shaft, so that the rotation of the Z-shaped frame 316 can be It is transformed into a horizontal driving force for the adjustment seat 312, so that the Z-shaped frame 316 cooperates with the sliding shaft, connecting frame 318, and sliding groove 319 to push the adjustment seat 312 and the first limiting wheel 313 to move toward the side of the burr processing component 5. During the movement, the first limiting wheel 313 drives the workpiece 4 to move toward the side of 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 to ensure that the position of the workpiece 4 is stable during the burr processing process, and there will be no shaking or deviation, thereby improving the quality and accuracy of the burr processing.

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