Description

Technical Field

[0001] This invention relates to the field of stainless steel workbench processing equipment, and more specifically, to a grinding device for blunting and deburring the edges of stainless steel workbench panels. Background Technology

[0002] Stainless steel workbenches, sheet metal office furniture, and metal products for logistics and turnover are widely used in cleanrooms, offices, and industrial warehousing. These products are mostly made from stainless steel sheets as the base material, processed through laser cutting, shearing, stamping, and bending. In actual production, after the sheets are cut, sharp edges and corners are often formed. If not properly treated, this not only increases the difficulty of subsequent assembly but also easily scratches operators during product transportation and daily use. It also affects the product's appearance and safety. Therefore, the industry generally requires the edges and corners of the panels to be blunted and deburred before final assembly.

[0003] Currently, in the production of sheet metal furniture and workbenches, there are various processing methods for passivation and deburring of panel-type workpieces. In some small and medium-sized production scenarios, manual processing using handheld angle grinders, files, and other tools is employed to process each edge and corner. This method has low equipment investment costs and can flexibly adapt to workpieces of different sizes and specifications, but the overall processing efficiency is not high. The passivation quality is highly correlated with the operator's experience and proficiency. The uniformity of rounded corners and the degree of burr removal of workpieces in the same batch are prone to fluctuations. Furthermore, long-term manual operation is labor-intensive, resulting in high labor costs for continuous production.

[0004] In some mass production scenarios, through-feed roller brush deburring equipment is used. This equipment relies on a conveyor line to continuously pass the sheet material through multiple sets of rotating grinding rollers, simultaneously deburring both the flat surfaces and straight edges of the sheet material, resulting in relatively higher processing efficiency. However, the grinding actuators in this type of equipment are mostly continuously rotating roller structures. When processing right-angled corners of panels, it is difficult to conform to the three-dimensional corner contours, often resulting in excessive grinding at the corner tips and insufficient removal of burrs at the corner roots, making it difficult to guarantee uniform passivation. Furthermore, this type of equipment typically only processes two long sides of the sheet material along the conveying direction. To complete the processing of all four sides of a rectangular panel, the workpiece orientation needs to be manually reversed, increasing the number of process steps. Its adaptability to pre-cut, independent panels is generally limited.

[0005] Another type of straight-line edge grinding device uses a fixture to fix the workpiece and drives the grinding head to reciprocate along the straight edge to achieve chamfering. The processing accuracy of the straight edge is relatively higher, and a more regular blunt edge can be obtained. However, most of these devices can only process straight edges and cannot cover the right-angle corner areas of the panel. The blunting operation at the corners usually needs to be completed manually, resulting in insufficient overall processing continuity and difficulty in achieving integrated processing of all edges and corners of the worktable panel, which to some extent restricts the improvement of production efficiency. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution.

[0007] A grinding device for blunting and deburring the edges of a stainless steel workbench panel includes a machine body, a fixing mechanism for securing the panel, and an X-axis moving mechanism, a Y-axis moving mechanism, and a Z-axis moving mechanism.

[0008] A mounting bracket is provided at the Z-axis moving mechanism, and a grinding mechanism for blunting the edges of the panel is provided at the mounting bracket. The grinding mechanism includes a grinding rod rotatably mounted at the mounting bracket, a grinding blade in the middle of the grinding rod for grinding the right-angled edges of the panel, and two opposing grinding cones slidably mounted at the grinding rod. The two opposing grinding cones are used to grind the upper and lower edges of the panel, respectively. The middle of the grinding cones is provided with rotating tooth grooves that are clearance-fitted with the grinding blades to allow the grinding cones and grinding rod to rotate synchronously. An adjustment mechanism is provided in the mounting bracket for adjusting the distance between the two grinding cones at the grinding rod.

[0009] As a preferred embodiment of the present invention, the mounting bracket is rotatably disposed at the Z-axis moving mechanism, and the Z-axis moving mechanism is provided with a mounting bracket driving mechanism for driving the mounting bracket to rotate. The X-axis moving mechanism and the Y-axis moving mechanism are used to cooperate with the mounting bracket driving mechanism so that the grinding mechanism can passivate different edges of the panel.

[0010] As a preferred embodiment of the present invention, the mounting bracket drive mechanism includes a motor mounting plate disposed at the Z-axis moving mechanism, a mounting bracket drive motor disposed at the motor mounting plate, and the rotating shaft of the mounting bracket drive motor being connected to the mounting bracket to drive the mounting bracket to rotate.

[0011] As a preferred embodiment of the present invention, the fixing mechanism includes an electric chuck assembly disposed on the machine tool body.

[0012] As a preferred embodiment of the present invention, a grinding rod drive motor is provided at the mounting bracket, and the rotating shaft of the grinding rod drive motor is connected to the grinding rod.

[0013] As a preferred embodiment of the present invention, a grinding cone mounting plate is provided at the adjacent end of the grinding cone, a grinding cone mounting plate through hole is provided at the grinding cone mounting plate, an annular connector is provided at the grinding cone, a bearing located in the through hole of the grinding cone mounting plate is sleeved at the annular connector, the end of the annular connector extends out of the through hole of the grinding cone mounting plate, and an annular connecting plate is provided at the end of the annular connector extending out of the through hole of the grinding cone mounting plate.

[0014] As a preferred embodiment of the present invention, the adjustment mechanism includes two electric push rods, which are disposed in the mounting bracket and respectively connected to the grinding cone mounting plate in the mounting bracket. The two electric push rods are used to drive the grinding cone mounting plates away from or closer to each other.

[0015] As a preferred embodiment of the present invention, the mounting bracket is provided with a set of optical axes, and the grinding cone mounting plate is provided with optical axis through holes that cooperate with the set of optical axes.

[0016] As a preferred embodiment of the present invention, the mounting bracket is further provided with a polishing mechanism for polishing the passivated panel. The polishing mechanism includes a polishing rod rotatably disposed between the mounting brackets, a polishing rod drive motor is provided at the mounting bracket, and a polishing disc is provided in the middle of the polishing rod for polishing the right-angled edges of the panel after grinding.

[0017] As a preferred embodiment of the present invention, the polishing mechanism further includes two polishing cones, which are disposed at the polishing rod. Each polishing cone has a hollow through hole that fits with the polishing rod with a clearance. The two polishing cones are connected to the grinding cone mounting plate in the same way as the grinding cone mounting plate. The large-diameter end of the grinding cone is provided with a first toothed ring, and the large-diameter end of the polishing cone is provided with a second toothed ring. The second toothed ring meshes with the first toothed ring so that the polishing cone can rotate with the rotation of the grinding cone.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention utilizes an openable grinding cone that engages with a central grinding cutting edge. During straight edge machining, the cone surface is used to chamfer the top and bottom edges. During corner machining, the cone is retracted, and the grinding cutting edge handles the corners, allowing for full-edge and corner passivation of the panel without manual re-grinding. Combined with the rotating switching function of the mounting bracket, machining of all four sides can be completed in a single clamping operation, reducing the need for multiple workpiece handling steps, thus improving production efficiency and reducing quality fluctuations caused by manual operation.

[0020] 2. This invention drives two grinding cones to slide along the grinding rod via an electric push rod, which can flexibly adjust the distance between the cones. It can be adapted to stainless steel workbench panels of different thicknesses, and the size of the chamfer can be adjusted according to process requirements. It eliminates the need for frequent grinding head replacements, shortens the preparation time for production changeovers, and is more suitable for the production mode of multi-variety, small-batch sheet metal furniture.

[0021] 3. This invention integrates a polishing mechanism next to the grinding mechanism, enabling passivation grinding and deburring polishing to be completed sequentially in a single clamping operation, reducing the need for workpiece transfer and secondary clamping. The straight-edge polishing utilizes the grinding power through gear ring meshing transmission, eliminating the need for a separate drive assembly for the polishing cone, resulting in a more compact structure.

Detailed Implementation

[0032] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0033] Example 1, such as Figures 1-8 As shown, this embodiment provides a stainless steel workbench panel edge blunting and deburring grinding device for blunting and deburring the edges and right angles of a cut stainless steel workbench panel. The device includes a machine tool body 110, with a fixing mechanism on the table surface for fixing the panel. In this embodiment, the fixing mechanism uses an electric suction cup assembly 140 mounted on the table surface of the machine tool body 110, which positions and fixes the workbench panel by negative pressure adsorption. The machine tool body 110 also has an X-axis moving mechanism 111, a Y-axis moving mechanism 112, and a Z-axis moving mechanism 113. These three moving mechanisms cooperate to adjust the position and feed path of the processing actuator in three-dimensional space.

[0034] Combination Figure 2 As shown, the output end of the Z-axis moving mechanism 113 is provided with a mounting bracket 120. The mounting bracket 120 is rotatably mounted on the Z-axis moving mechanism 113. The Z-axis moving mechanism 113 is correspondingly provided with a mounting bracket drive mechanism for driving the mounting bracket 120 to rotate around the vertical axis. The mounting bracket drive mechanism includes a motor mounting plate 130 fixedly mounted on the Z-axis moving mechanism 113. A mounting bracket drive motor 230 is mounted on the motor mounting plate 130. The lower end of the rotating shaft of the mounting bracket drive motor 230 is connected to the top of the mounting bracket 120 for driving the mounting bracket 120 to rotate as a whole. The X-axis moving mechanism 111 and the Y-axis moving mechanism 112 can cooperate with the mounting bracket drive mechanism to switch the processing actuator to different sides of the panel, realizing continuous processing of multiple edges of a single panel.

[0035] A grinding mechanism for blunting the edges of the panel is provided at the mounting bracket 120. The grinding mechanism includes a grinding rod 210 rotatably mounted between the two side plates of the mounting bracket 120. A grinding rod drive motor 240 is correspondingly mounted on the side plate of the mounting bracket 120. The shaft of the grinding rod drive motor 240 is coaxially connected to the end of the grinding rod 210, driving the grinding rod 210 to rotate at high speed around its own axis. Figure 3 As shown, the grinding rod 210 has a grinding blade 310 in the middle, which is used to grind and blunt the right-angled end of the panel; combined with Figure 4 As shown, two opposing grinding cones 220 are slidably sleeved on the body of the grinding rod 210. The conical surfaces of the two grinding cones 220 are arranged opposite each other and are used to grind and chamfer the upper and lower end edges of the panel respectively.

[0036] The grinding cone 220 has a toothed groove 410 in the middle, which is in clearance fit with the grinding cutting edge 310 on the grinding rod 210. This structure allows the grinding cone 220 to slide along the axial direction of the grinding rod 210 to adjust the spacing. On the other hand, the torque can be transmitted through the engagement of the teeth and grooves, so that the grinding cone 220 can rotate synchronously with the grinding rod 210.

[0037] Combination Figure 5 , Figure 6 As shown, each of the two adjacent ends of the grinding cone cylinders 220 is provided with a grinding cone cylinder mounting plate 250. The grinding cone cylinder mounting plate 250 has a grinding cone cylinder mounting plate through hole 610 on its plate body. The grinding cone cylinder 220 is provided with an annular connector 420 on the side facing the grinding cone cylinder mounting plate 250. A bearing 620 is sleeved on the outer wall of the annular connector 420 and is embedded in the grinding cone cylinder mounting plate through hole 610. The end of the annular connector 420 extends out of the grinding cone cylinder mounting plate through hole 610, and an annular connecting plate 630 is fixed on the outer wall of the extended end. The annular connecting plate 630 abuts against the end face of the bearing 620, realizing the rotational connection between the grinding cone cylinder 220 and the grinding cone cylinder mounting plate 250. That is, when the grinding cone cylinder 220 rotates, the grinding cone cylinder mounting plate 250 remains stationary.

[0038] Combination Figure 7As shown, the mounting bracket 120 is equipped with an adjustment mechanism for adjusting the distance between the two grinding cones 220. The adjustment mechanism includes two electric push rods 260, both of which are fixed inside the mounting bracket 120. The output ends of the two electric push rods 260 are respectively connected to the corresponding grinding cone mounting plates 250. The two electric push rods 260 extend and retract synchronously, which can drive the two grinding cone mounting plates 250 to move closer or further apart, thereby causing the two grinding cones 220 to slide along the axial direction of the grinding rod 210 to achieve distance adjustment. A set of optical shafts 710 is fixed inside the mounting bracket 120. Optical shaft through holes 720 that cooperate with the optical shafts 710 are correspondingly opened on the plate body of the grinding cone mounting plates 250. The optical shafts 710 pass through the optical shaft through holes 720 to provide guidance for the sliding of the grinding cone mounting plates 250, improve the smoothness of the distance adjustment process, and prevent the grinding cones 220 from wobbling.

[0039] A polishing mechanism is also provided at mounting bracket 120 for deburring and polishing the edges of the passivated panel. Figure 8 As shown, the polishing mechanism includes a polishing rod 510 rotatably disposed between the two side plates of the mounting bracket 120. A polishing rod drive motor 520 is correspondingly installed on the side plate of the mounting bracket 120. The rotating shaft of the polishing rod drive motor 520 is coaxially connected to the end of the polishing rod 510 to drive the polishing rod 510 to rotate. A polishing disc 810 is fixed in the middle of the polishing rod 510 for polishing and finishing the right-angled ends of the panel after grinding.

[0040] The polishing mechanism also includes two polishing cones 530, which are fitted onto the polishing rod 510. Each polishing cone 530 has a hollow through-hole 531 in its middle, which is clearance-fitted with the polishing rod 510, allowing the polishing cone 530 to slide axially along the polishing rod 510 without directly rotating with it. The two polishing cones 530 adopt the same connection structure as the grinding cone 220 and are correspondingly installed on the grinding cone mounting plate 250 on the same side, allowing their spacing to be adjusted synchronously with the grinding cone mounting plate 250. A first gear ring 540 is fixed to the large-diameter end face of the grinding cone 220, and a second gear ring 550 is correspondingly fixed to the large-diameter end face of the polishing cone 530. The second gear ring 550 meshes with the first gear ring 540. When the grinding cone 220 rotates, the polishing cone 530 can be driven to rotate synchronously through the meshing of the first gear ring 540 and the second gear ring 550, thereby providing rotational power for the polishing cone 530.

[0041] Before processing, the stainless steel worktable panel to be processed is moved to the table area of ​​the machine tool body 110. The electric chuck assembly 140 is activated to generate negative pressure, which stably and securely holds the worktable panel, completing the clamping and positioning. After clamping, the grinding and polishing processes are carried out sequentially, as follows:

[0042] First, the straight edge section is ground and passivated. Through the coordinated movement of the X-axis moving mechanism 111, Y-axis moving mechanism 112, and Z-axis moving mechanism 113, the grinding mechanism is moved to the first side edge of the panel to be processed. Based on the panel thickness and the passivation chamfer requirements, the electric push rod 260 is activated to adjust the distance between the two grinding cones 220, aligning the conical surfaces of the two grinding cones 220 with the edges of the upper and lower end faces of the panel. After adjustment, the grinding rod drive motor 240 is activated, causing the grinding rod 210 and the two grinding cones 220 to rotate synchronously at high speed. Subsequently, the Y-axis moving mechanism 112 is controlled to drive the grinding mechanism to feed at a uniform speed along the edge direction, continuously grinding the edges of the upper and lower end faces of the panel through the conical surfaces of the grinding cones 220, forming a uniform passivation chamfer.

[0043] When the grinding mechanism feeds along the edge to the right-angle end of the panel, the Y-axis moving mechanism 112 pauses feeding. Then, the electric push rod 260 moves the two grinding cone mounting plates 250 away from each other, causing the two grinding cones 220 to retract synchronously to both sides, exposing the grinding cutting edge 310 in the middle of the grinding rod 210. The X-axis moving mechanism 111 and the Z-axis moving mechanism 113 finely adjust the position so that the grinding cutting edge 310 abuts against the right-angle edge of the panel. The rotating grinding cutting edge 310 grinds and blunts the right-angle end, completing the transition machining at the edge. After the edge machining is completed, the electric push rod 260 drives the grinding cone 220 to reset, preparing for the next stage of machining.

[0044] After the single edge and corresponding corner are machined, the X-axis moving mechanism 111 and the Y-axis moving mechanism 112 drive the grinding mechanism to move to the vicinity of the next side edge to be machined on the panel; the mounting bracket drive motor 230 is started, driving the mounting bracket 120 to rotate, so that the axis of the grinding rod 210 is kept parallel to the side edge to be machined. By repeating the above straight edge grinding and corner grinding steps, the grinding and passivation of the four side edges and four right-angle ends of the worktable panel can be completed in sequence.

[0045] After all grinding processes are completed, the polishing process is initiated to deburr and improve the surface finish of the edges. The polishing path and side-edge switching method are basically the same as those in the grinding process. The specific processing procedure is as follows:

[0046] The polishing mechanism is positioned so that the two polishing cones 530 are aligned with the passivated surfaces of the upper and lower end faces of the panel, respectively. The grinding rod drive motor 240 continues to operate, and the grinding cone 220 rotates continuously. Through the engagement of the first gear ring 540 and the second gear ring 550 at the end, the polishing cone 530 is driven to rotate synchronously. The moving mechanism drives the polishing mechanism to feed at a constant speed along the straight edge. The rotating polishing cone 530 polishes the passivated surfaces of the upper and lower edges, removing fine burrs remaining from grinding and improving the edge smoothness. During this process, the polishing rod 510 does not drive the polishing cone 530, but only provides sliding support for the polishing cone 530.

[0047] When the feed reaches the right-angle end, the polishing cone 530 retracts to both sides synchronously with the grinding cone mounting plate 250, exposing the polishing disc 810 in the middle of the polishing rod 510. The polishing rod drive motor 520 is started, driving the polishing rod 510 and the polishing disc 810 to rotate. The polishing disc 810 polishes and trims the blunt surface at the right-angle corner, ensuring the smoothness of the corner transition. After the corner polishing is completed, the polishing cone 530 returns to its original position, and the next straight edge polishing continues.

[0048] The side-switching method is the same as the grinding process. The polishing direction is adjusted by rotating the mounting bracket 120, and all edges and corners are polished in sequence. After all processing is completed, the electric suction cup assembly 140 releases the negative pressure, and the processed worktable panel can be removed.

[0049] The stainless steel workbench edge blunting and deburring grinding device in this embodiment achieves the following technical effects through the above-described technical solution:

[0050] 1. Addressing the issue that existing straight edge grinding devices can only handle straight edges and corners requiring manual re-grinding, the stainless steel workbench panel edge blunting and deburring grinding device in this embodiment utilizes an openable grinding cone 220 in conjunction with a central grinding blade 310. During straight edge processing, the cone surface is used to chamfer the upper and lower edges; during corner processing, the cone is retracted, and the grinding blade 310 handles the corners, completing the blunting of all edges and corners of the panel without manual re-grinding. Combined with the rotating switching function of the mounting bracket 120, processing of all four sides can be completed in a single clamping operation, reducing the number of workpiece handling steps and improving production efficiency while minimizing quality fluctuations caused by manual operation.

[0051] 2. Addressing the issue of fixed grinding head specifications and inconvenience in changing heads when adapting to different sheet thicknesses, the stainless steel workbench edge-buffing and deburring grinding device in this embodiment uses an electric push rod 260 to drive two grinding cones 220 to slide along the grinding rod 210. This allows for flexible adjustment of the cone spacing, enabling it to adapt to stainless steel workbench panels of different thicknesses and adjust the chamfering dimensions according to process requirements. This eliminates the need for frequent grinding head changes, shortens preparation time for production changes, and is more suitable for the production mode of multi-variety, small-batch sheet metal furniture. Simultaneously, the polishing cone 530 and the grinding cone 220 adjust their spacing synchronously, allowing for simultaneous adaptation to both grinding and polishing processes with a single adjustment, making operation more convenient.

[0052] 3. In this embodiment, the stainless steel workbench panel edge passivation and deburring grinding device integrates a polishing mechanism next to the grinding mechanism. It can complete passivation grinding and deburring polishing in a single clamping, reducing the workpiece transfer and secondary clamping processes. The straight edge polishing utilizes the grinding power through gear ring meshing transmission, eliminating the need for a separate drive component for the polishing cone 530, resulting in a more compact structure. The edges are fitted with dedicated polishing discs 810 for finishing, which can improve the smoothness of the edge transition, reduce the workload of subsequent manual operations, and help improve the processing quality and stability of workpieces in the same batch.

[0053] 4. Compared to the higher purchase and maintenance costs of multi-axis robotic grinding units, the stainless steel workbench panel edge-blunting and deburring grinding device in this embodiment adopts a three-axis moving mechanism combined with a dedicated grinding and polishing head. The overall structure is relatively simple, and the equipment investment cost is more controllable. For pre-cut, independent workbench panels, this device is more adaptable than through-feed roller brush equipment, requires no continuous conveyor line, and is more suitable for the production layout of small and medium-sized sheet metal processing enterprises, thus possessing good potential for widespread adoption.

[0054] In summary, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention should be covered by the present invention.

The large diameter end of the grinding cone (220) is provided with a first toothed ring (540), and the large diameter end of the polishing cone (530) is provided with a second toothed ring (550). The second toothed ring (550) meshes with the first toothed ring (540) so that the polishing cone (530) can rotate with the rotation of the grinding cone (220).
