[0002] In the field of ball-jointed railing processing, weld grinding is a key step in ensuring product surface quality and structural safety. Existing technology mainly relies on manual handheld grinding machines to grind the welds of ball-jointed railings one by one.

[0003] However, the above manual polishing method cannot meet the requirements of automated and efficient production and has the following disadvantages:

[0004] 1. Existing equipment is often equipped with only a single telescopic cylinder or a single motor to drive a grinding head. Due to the existence of single and double welds at the ball joint position, it is difficult to process multiple welds at the same time, resulting in low production efficiency.

[0005] 2. Traditional rigid grinding wheels or flap wheels are difficult to fully fit with different ball diameters or weld surfaces, and are prone to local over-grinding or residual burrs, affecting the consistency of grinding quality.

[0006] 3. Traditional equipment mostly relies on manual loading, and the unloading process is cumbersome, making it difficult to achieve continuous production on an assembly line. Summary of the Invention

[0010] Preferably, the single-sided grinding piece includes a first elastic matrix, a second elastic matrix and a third elastic matrix, which are fixed in sequence to form a single-sided step shape, and are used to grind the single-sided weld position of the ball-jointed railing.

[0011] Preferably, the double-sided grinding piece includes a first elastic matrix, a second elastic matrix and a third elastic matrix. The second elastic matrix and the third elastic matrix are fixed on both sides of the first elastic matrix in sequence to form a double-sided stepped shape, and a V-shaped grinding portion is formed between the double-sided steps, which is used to grind the double-sided weld positions of the ball-jointed railing.

[0012] Preferably, the first elastic matrix, the second elastic matrix and the third elastic matrix are all rubber-wrapped metal disks, and the outer wall of the rubber is embedded with multiple alloy particles with a corrugated cross-section, so that when the elastic matrix contacts the curved surface, the elastic matrix deforms to adaptively adjust the protrusion of the alloy particles.

[0013] Preferably, the other single output shaft of the dual-axis motor is connected to a dust removal assembly, which includes a dust removal cylinder. Both ends of the dust removal cylinder are provided with openings, and a first activated carbon filter and a second activated carbon filter are respectively installed inside the openings.

[0014] Preferably, a connecting rod is fixed between the first activated carbon filter and the second activated carbon filter. The connecting rod passes through the dust removal cylinder, and an exhaust fan blade is installed at one end of the connecting rod located in the dust removal cylinder.

[0015] Preferably, a third telescopic cylinder is installed on the outer side of the fixed plate body, the piston rod of the third telescopic cylinder passes through the fixed plate body, and the end of the piston rod is provided with a mounting groove, a first drive motor is installed inside the mounting groove, the output shaft of the first drive motor extends from the mounting groove, and a clamping disc is fixed to the extended end thereof.

[0016] Preferably, a plurality of conveying rollers are provided between the plurality of fixed plates, and the plurality of conveying rollers are externally connected to a conveyor belt. One end of the conveying roller at the front end is connected to the output shaft of the second drive motor, and the second drive motor is installed on the outer side of the fixed plate body. The conveying roller at the rear end is connected to the fixed plate body through a bearing.

[0017] Preferably, a groove is provided on the top of the bottom plate of the equipment, a receiving plate body is detachably connected to the inside of the groove, and a receiving groove is provided on the top of the receiving plate body for catching the metal dust particles falling from the conveyor belt surface.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention combines a concave plate, an electromagnetic rod and a grinding assembly, not only arranging a plurality of grinding pieces, allowing the plurality of grinding pieces to grind the plurality of ball joints on the ball joint railing respectively, but also, because the grinding pieces include two types, a single-sided grinding piece and a double-sided grinding piece, it is possible to grind the single-sided ball joint and the double-sided ball joint on the ball joint railing at the same time, thereby effectively improving the grinding efficiency. At the same time, by moving the moving block on the surface of the electromagnetic rod and limiting it with a limit bolt, the positions of the plurality of grinding pieces can be adjusted, thereby meeting the grinding requirements of ball joints at different positions. In addition, the grinding piece adopts a corrugated composite material embedded in the outer wall of a metal disk wrapped in rubber. Gold particles form a stepped elastic grinding tool, which can be adaptively adjusted according to the actual situation of the ball diameter and the weld surface to ensure the consistency and quality of grinding. At the same time, the gap between its corrugated structure and the steps can generate micro-vibration, which plays a role in assisting chip removal. It solves the technical problem that existing equipment is often only equipped with a single telescopic cylinder or a single motor to drive a grinding head. Due to the existence of single and double welds at the ball joint position, it is difficult to process multiple welds in parallel at the same time, resulting in low production efficiency. Traditional rigid grinding wheels or flap wheels are difficult to fully fit with different ball diameters or weld surfaces, and are prone to local over-grinding or residual burrs, affecting the consistency of grinding quality.

[0020] 2. The present invention combines a dual-axis motor and a dust removal component. During the operation of the equipment, one end of the dual-axis motor drives the grinding part to perform efficient grinding operations on the workpiece, and the other end drives the dust removal cylinder to start rotating. As the dust removal cylinder rotates, the exhaust fan blades arranged inside it also start to operate, forming a negative pressure airflow in the cylinder. The airflow quickly sucks the metal dust particles generated in the grinding process into the dust removal cylinder and makes them adhere to the surface of the activated carbon filter in the cylinder, effectively preventing the metal dust particles from floating in the air. Not only that, activated carbon filters are installed at both ends of the dust removal cylinder, so that the equipment can not only have the dust removal function, but also filter and treat harmful gases in the welding or grinding room. The dust removal mechanism and the grinding mechanism are integrated into one, which simplifies the equipment structure.

[0021] 3. The present invention uses a conveyor belt, a third telescopic cylinder and a drive motor, which can not only utilize the conveyor belt to directly transport multiple ball-jointed railings continuously, but also, when the ball-jointed railings arrive between the corresponding two third telescopic cylinders, the third telescopic cylinder can drive the clamping plate to achieve clamping and limiting of the ball-jointed railings. Moreover, a drive motor is provided inside the piston rod of the third telescopic cylinder, which can drive the ball-jointed railings to rotate, and the rotation direction of the ball-jointed railings is opposite to the rotation direction of the grinding part. During the grinding process, when the ball-jointed railings and the grinding part rotate in opposite directions, the relative movement speed between the two is greatly increased. The increase in the relative movement speed makes the contact and friction between the abrasive on the grinding part and the surface of the ball-jointed railings more frequent and intense, further improving the grinding effect.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0028] Example 1: An efficient grinding device for ball-jointed railings, see Figures 1 to 4, including an equipment base plate 1, fixed plate bodies 101 are fixed on both sides of the top of the equipment base plate 1, one end of a support rod 102 is fixed to the front and rear ends of the top of the fixed plate body 101, and the other end of the support rod 102 is fixed to an equipment top plate 103, characterized in that a first telescopic cylinder body 201 is installed on the top of the equipment top plate 103, the piston rod at the bottom of the first telescopic cylinder body 201 passes through the equipment top plate 103 and is fixed with a concave plate body 202, an electromagnetic rod 203 is fixed inside the concave plate body 202, and a plurality of moving blocks 204 are passed through the outside of the electromagnetic rod 203, and a limiting bolt 209 is passed through the front end of the moving block 204, and the limiting bolt 209 is connected to the screw hole in the moving block 204.

[0029] Before performing the grinding operation, the positions of multiple grinding parts are adjusted according to the ball joint welds of the ball joint railing. When adjusting, the electromagnetic rod 203 is first closed, and then the multiple moving blocks 204 are slid and adjusted on the surface of the electromagnetic rod 203 respectively. After the sliding adjustment is completed, the electromagnetic rod 203 is started, and the electromagnetic rod 203 is magnetically connected to the moving block 204, and the limit bolt 209 is rotated so that the limit bolt 209 is against the surface of the electromagnetic rod 203, thereby adjusting and limiting the position of the grinding part.

[0030] For details, see Figure 1 and Figure 3 , a grinding assembly is provided at the bottom of the moving block 204, and the grinding assembly includes a second telescopic cylinder 205, the second telescopic cylinder 205 is installed at the bottom of the moving block 204, and the piston rod at the bottom thereof is fixed with a dual-axis motor 210, and the output shaft at one end of the dual-axis motor 210 is connected with a grinding piece, and the grinding piece includes a single-sided grinding piece and a double-sided grinding piece, and the single-sided grinding piece includes a first elastic base 211, a second elastic base 212 and a third elastic base 213. The first elastic base 211, the second elastic base 212 and the third elastic base 213 are fixed in sequence to form a single-sided step shape, which is used to grind the single-sided weld position of the ball-jointed railing, and double-sided grinding The component includes a first elastic base 211, a second elastic base 212 and a third elastic base 213. The second elastic base 212 and the third elastic base 213 are fixed on both sides of the first elastic base 211 in sequence, forming a double-sided stepped shape, and a V-shaped polishing portion is formed between the double-sided stepped shapes, which is used to polish the double-sided weld positions of the ball-jointed railing. The first elastic base 211, the second elastic base 212 and the third elastic base 213 are all rubber-wrapped metal disks, and the outer wall of the rubber is embedded with multiple alloy particles 214 with a corrugated cross-section. When the elastic base contacts a curved surface, the elastic base deforms to adaptively adjust the protrusion of the alloy particles 214.

[0031] After the adjustment is completed, the first telescopic cylinder 201 can be started, and the first telescopic cylinder 201 will drive the concave plate 202 to move downward, and the concave plate 202 will drive the electromagnetic rod 203 and multiple grinding pieces to move downward, so that the grinding pieces contact the surface of the ball joint weld. Since the grinding pieces include two types: single-sided grinding pieces and double-sided grinding pieces, the single-sided step shape and double-sided step shape formed by the first elastic base 211, the second elastic base 212 and the third elastic base 213 of the single-sided grinding piece and the double-sided grinding piece can be used to contact the single-sided weld and double-sided weld positions of the ball joint railing respectively for grinding, thereby achieving simultaneous grinding of the single-sided ball joint weld and the double-sided ball joint weld on the ball joint railing, effectively improving the grinding efficiency;

[0032] At the same time, the metal disc in the structure of rubber wrapped in metal disc provides rigid support to ensure the grinding force. The rubber layer acts as an elastic medium, allowing the grinding tool to undergo local deformation when contacting ball-joint welds of different curvatures. The corrugated alloy particles 214 embedded in the outer wall are arranged in a stepped manner to form a multi-level contact surface. When the grinding tool is pressed against the weld, the particles with higher steps preferentially contact the raised parts, and the particles with lower steps then fit the recessed areas, achieving step-by-step adaptive grinding. The corrugated shape of the alloy particles 214 can increase the density of contact points with the spherical surface, and automatically adjust the particle embedding depth through the compression feedback of the elastic rubber to ensure the best grinding performance. To ensure that the welds of spheres with different diameters can all obtain uniform grinding force, during grinding, the difference in friction between the corrugated particles and the weld surface causes the grinding tool to vibrate slightly. The vibration frequency is related to the grinding speed, which can destroy the adsorption force between the debris and the grinding tool surface. The gaps between adjacent steps form capillary channels. During the vibration process, air is quickly inhaled and discharged, generating a pulsed airflow, which blows the debris embedded between the alloy particles 214 to the edge of the grinding tool. The resilience of the rubber layer pushes the alloy particles 214 to reset after each vibration, forming a cycle of contact, vibration, chip removal, and reset, and continuously maintaining the cleanliness of the grinding interface.

[0033] For further information, see Figure 2 The other single output shaft of the dual-axis motor 210 is connected to a dust removal component, which includes a dust removal cylinder 3. Openings are provided at both ends of the dust removal cylinder 3, and a first activated carbon filter 301 and a second activated carbon filter 302 are respectively installed inside the openings. A connecting rod 303 is fixed between the first activated carbon filter 301 and the second activated carbon filter 302. The connecting rod 303 passes through the dust removal cylinder 3, and an exhaust fan blade 304 is installed at one end of the connecting rod 303 located inside the dust removal cylinder 3.

[0034] One end of the dual-axis motor 210 drives the grinding piece to grind the workpiece efficiently, and at the same time the other end drives the dust removal cylinder 3 to rotate, so that the internal exhaust fan blades 304 generate negative pressure airflow, and the metal dust and harmful gases generated by grinding are sucked into the cylinder through the suction port. The airflow carries the particles through the activated carbon filter at both ends of the cylinder in turn. The front filter intercepts large particles of dust, and the rear filter further absorbs fine particles and harmful gases, achieving the dual effects of dust capture and gas purification.

[0035] It should be noted that during the grinding process, the load fluctuations (such as impact loads) generated when the grinding tool contacts the workpiece have high-frequency and short-time characteristics, while the torque required for exhaust is a steady-state low-frequency load. The motor rotor's own rotational inertia can effectively buffer the instantaneous torque impact at the grinding end and prevent it from being transmitted to the exhaust end, thereby avoiding the grinding operation affecting the rotation speed of the exhaust fan blades 304 and ensuring a constant dust removal air volume.

[0036] It is worth emphasizing that see Figure 1 A third telescopic cylinder 2 is installed on the outer side of the fixed plate body 101. The piston rod of the third telescopic cylinder 2 passes through the fixed plate body 101, and a mounting groove 215 is provided at the end of the piston rod. A first drive motor 216 is installed inside the mounting groove 215. The output shaft of the first drive motor 216 extends from the mounting groove 215, and a clamping disc 217 is fixed to one end of the extended end.

[0037] When it is necessary to transport multiple ball-jointed railings, the second drive motor 208 is started, and the second drive motor 208 is used to drive the conveying roller 206 at the front end to rotate. The conveying roller 206 will drive the conveyor belt 207 to rotate, and the conveyor belt 207 drives the multiple conveying rollers at the rear end to rotate, so that the conveyor belt 207 is used to directly transport multiple ball-jointed railings continuously. When the ball-jointed railings arrive between the corresponding two third telescopic cylinders 2, the third telescopic cylinder 2 can be started to drive the clamping disc 217 to move, so as to achieve the clamping limit of the ball-jointed railings. In addition, the first drive motor 216 is provided inside the piston rod of the third telescopic cylinder 2. After the first drive motor 216 is started, the clamping disc 21 7 rotates, the clamping disc 217 will drive the ball-jointed railing to rotate, and the rotation direction of the ball-jointed railing is opposite to that of the grinding piece. During the grinding process, when the ball-jointed railing and the grinding piece rotate in opposite directions, the relative motion speed between the two is greatly increased. The acceleration of the relative motion speed makes the contact and friction between the abrasive on the grinding piece and the surface of the ball-jointed railing more frequent and intense. The high-frequency and intense friction can more effectively remove burrs, rust, oxide layers and other impurities on the surface of the ball-jointed railing, making the surface smoother. At the same time, for some minor uneven places, the rotation in the opposite direction can also allow the grinding piece to more comprehensively cover the surface of the ball-jointed railing, avoiding the occurrence of grinding dead corners, thereby improving the quality and effect of grinding.

[0038] It is worth noting that, see Figure 1 A plurality of conveying rollers 206 are provided between the plurality of fixed plates 101, and the external transmission of the plurality of conveying rollers 206 is connected to the conveyor belt 207. One end of the conveying roller 206 at the front end is connected to the output shaft of the second drive motor 208, and the second drive motor 208 is installed on the outer side of the fixed plate 101. The conveying roller 206 at the rear end is connected to the fixed plate 101 through a bearing. A groove 104 is provided on the top of the equipment base plate 1, and a receiving plate 105 is detachably connected to the inside of the groove 104. A receiving trough is provided on the top of the receiving plate 105 for catching the metal dust particles that fall from the surface of the conveyor belt 207.

[0039] During the grinding process, some metal dust particles generated by grinding will fall onto the surface of the conveyor belt 207. When the conveyor belt 207 continues to move, the metal dust particles will directly fall into the receiving trough of the receiving plate 105 at the top of the equipment base plate 1, thereby automatically collecting the metal dust particles.

[0040] In the present invention, the plurality of third telescopic cylinders 2 and the first drive motor 216 are connected to an external synchronous controller to achieve synchronous control of the plurality of third telescopic cylinders 2 and the first drive motor 216 .

[0041] In addition, the components designed in the present invention are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. They can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to internal structures and methods.
