Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of workpiece deburring equipment, and in particular to a rear-mounted robot deburring equipment. Background Technology
[0002] In the manufacturing of automotive chassis structural components, the deburring process is crucial for assembly accuracy and driving safety. Traditional manual deburring is inefficient and produces inconsistent quality, while existing automated equipment, although using industrial robots to replace manual labor, suffers from layout and structural design flaws that make it difficult to meet the demands of high-efficiency, high-precision, and multi-size compatible production lines.
[0003] In current mainstream solutions, robots are typically positioned in front of or around the workpiece clamping module, resulting in redundant lateral dimensions of the equipment and making it difficult to adapt to compact production lines. Simultaneously, the robot arm's movements are prone to interference with fixed clamping mechanisms, limiting the end effector's posture adjustment capabilities, particularly hindering the precision of grinding burrs on curved or bent surfaces. Furthermore, the equipment's center of gravity is shifted towards the working side due to the robot's forward positioning, leading to increased vibration and significantly reduced positioning stability when clamping large workpieces (such as SUV chassis beams).
[0004] Existing clamping modules mostly adopt a fixed structure, which cannot be compatible with workpieces of different lengths and widths (such as the size difference between the chassis beams of cars and SUVs), requiring frequent changes of clamps or the configuration of multiple special equipment; some improved solutions use slide rails to move the clamping module to adapt to the length of the workpiece, but lack a radial and axial coordinated clamping mechanism, resulting in workpiece positioning deviation. Utility Model Content

[0006] A grinding table with a robot on one side for grinding workpieces;
[0007] The clamping module is used to clamp the workpiece to be polished, and it is located on the opposite side of the polishing table.
[0008] Furthermore, the robot's working end is equipped with a retractable tool holder, on which a grinding head for grinding workpieces is mounted.
[0009] Furthermore, the clamping module includes:
[0010] A first clamping assembly is used for radial clamping of the workpiece;
[0011] The second clamping assembly is used for axial clamping of the workpiece.
[0012] Furthermore, the first clamping component includes:
[0013] A first baffle and a first actuator are arranged adjacent to each other. The first actuator is used to push the workpiece to the first baffle for clamping.
[0014] The second actuator has a clamping element at its output end. When the output end of the second actuator moves, it drives the clamping element to clamp the workpiece.
[0015] The output directions of the first actuator and the second actuator are perpendicular to each other.
[0016] Furthermore, the second clamping component includes:
[0017] The second baffle and the third actuator are connected to the second baffle.

[0020] Furthermore, it also includes a cleaning module, which is arranged adjacent to the clamping module, for cleaning the residue left during polishing.
[0021] Furthermore, the cleaning module includes an air nozzle that is connected to an external air source.
[0022] According to the rear-mounted robot grinding equipment of this utility model embodiment, the rear-mounted robot design makes the equipment structure more compact and balances the center of gravity, reducing vibration when clamping large workpieces; at the same time, it can be compatible with workpieces of different lengths, and combines radial-axial clamping components for coordinated locking and width adjustment of eccentric guide columns; it is also equipped with a retractable tool holder and air nozzle cleaning module, which removes residue in real time while grinding flexibly.

[0025] Figure 2 This is a schematic diagram of the clamping module of the rear-mounted robot grinding device according to an embodiment of the present utility model;
[0026] Figure 3 This is a schematic diagram of the guide column of the rear-mounted robot grinding device according to an embodiment of the present utility model. Detailed Implementation
[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.
[0028] First, combine Figures 1-3 The rear-mounted robot grinding equipment according to the embodiments of the present utility model is used for grinding workpieces with different lengths, widths and thicknesses, and has a wide range of applications.
[0029] like Figure 1 As shown, the rear-mounted robot polishing device of this utility model embodiment includes: a polishing table 1 and a clamping module 2.
[0030] Specifically, such as Figure 1 As shown, a robot 4 is mounted on one side of the grinding table 1, and the robot 4 is used to grind the workpiece. A clamping module 2 is used to clamp the workpiece to be ground, and the clamping module 2 is located on the opposite side of the grinding table 1. The overall equipment is more compact. In this embodiment, the grinding table 1 is equipped with a pair of robots 4 and a pair of clamping modules 2, with each robot 4 corresponding to one clamping module 2. This results in higher grinding efficiency compared to using only one robot 4. When the side containing the clamping module 2 is considered the front, the robot 4 is positioned at the rear. This design prevents redundancy in the lateral dimensions of the equipment, making it difficult to adapt to compact production lines. Simultaneously, placing the robot 4 at the rear prevents the center of gravity of the entire equipment from shifting, ensuring stable operation and improved grinding accuracy during the grinding and deburring process.
[0031] like Figure 1 As shown in this embodiment, a slide rail 5 is also provided below one of the clamping modules 2, and the entire clamping module 2 can move on the slide rail 5, so that it can be used for clamping and grinding workpieces of different lengths.
[0032] Furthermore, the working end of robot 4 is equipped with a retractable tool holder, which can flexibly grind burrs on curved surfaces. A grinding head for grinding workpieces is installed on the tool holder.
[0033] Furthermore, the clamping module 2 includes: a first clamping component 21 for radial clamping of the workpiece; and a second clamping component 22 for axial clamping of the workpiece. This clamping structure ensures that the workpiece does not shift during the grinding process, making it more stable and achieving higher grinding accuracy.
[0034] Furthermore, such as Figure 1 , Figure 2As shown, the first clamping assembly 21 includes: a first baffle 211, a first actuator 212, and a second actuator 213; the first baffle 211 is arranged adjacent to the output end of the first actuator 212, and the first actuator 212 is used to push the workpiece to the first baffle 211 for clamping; the output end of the second actuator 213 is provided with a clamping member 214, and when the output end of the second actuator 213 moves, it drives the clamping member 214 to clamp the workpiece; the movement directions of the output ends of the first actuator 212 and the second actuator 213 are perpendicular to each other.
[0035] In this embodiment, both the first actuator 212 and the second actuator 213 are cylinders. When the workpiece is radially clamped, the output end of the first actuator 212 extends to press the workpiece against the first baffle 211; the second actuator 213 retracts, driving the clamping member 214 to press the workpiece. The radial clamping of the workpiece can be achieved through the first actuator 212 and the second actuator 213.
[0036] Furthermore, such as Figure 1 , Figure 2 As shown, the second clamping assembly 22 includes a second baffle 221 and a third actuator 222. The third actuator 222 is connected to the second baffle 221. The second baffle 221 is used to hold one end of the workpiece. The output end of the third actuator 222 moves to contact the other end of the workpiece. The second baffle 221 and the third actuator 222 work together to clamp the workpiece axially.
[0037] In this embodiment, the second baffle 221 is mounted on a clamping module 2 and is driven by a cylinder to extend and retract vertically. The third actuator 222 is mounted on another clamping module 2 and is also a cylinder. When axially clamping the workpiece, the workpiece is placed on the two clamping modules 2. One end of the workpiece will abut against the second baffle 221, and the other end will be pressed against the second baffle 221 by the third actuator 222 when it retracts, thus achieving axial clamping of the workpiece.
[0038] Furthermore, such as Figure 2 , Figure 3 As shown, the clamping module 2 also includes: a guide post 23, which is arranged adjacent to the first baffle 211. The guide post 23 and the first baffle 211 form a workpiece placement area, and the workpiece is placed in the workpiece placement area.
[0039] Furthermore, the guide column 23 is an eccentric column, which makes it convenient to adjust the width of the workpiece placement area according to the different widths of the workpiece.
[0040] Furthermore, such as Figure 2As shown, it also includes: a cleaning module 3, which is arranged adjacent to the clamping module 2, and is used to clean the residue left during grinding to avoid the accumulation of residue affecting the quality of the processed surface.
[0041] Furthermore, such as Figure 2 As shown, the cleaning module 3 includes an air nozzle 31, which is connected to an external air source and is used to blow away the iron filings from the grinding process.
[0042] In use, the workpiece to be polished is placed in the workpiece placement area using external equipment. The second baffle 221 rises, and the third actuator 222 begins to retract, moving the workpiece towards the second baffle 221 until one end of the workpiece abuts against it. At this point, the third actuator 222 stops moving, and the axial clamping of the workpiece is complete. Then, the first actuator 212 moves the workpiece towards the first baffle 211 until it contacts the first baffle 211 and stops. The second actuator 213 begins to retract, moving the clamping member 214 downward to clamp the workpiece, thus completing the radial clamping of the workpiece. After the entire clamping process is completed, the robot 4 starts to polish the burrs on the workpiece.
[0043] Above, refer to Figures 1-3 The present invention describes a rear-mounted robot grinding device according to an embodiment of the present invention. The rear-mounted robot design makes the device structure more compact and balances the center of gravity, reducing vibration when clamping large workpieces. It is also compatible with workpieces of different lengths, and combines radial-axial clamping components for coordinated locking and width adjustment of eccentric guide columns. It is also equipped with a retractable tool holder and an air nozzle cleaning module to remove residues in real time while grinding flexibly.
