Description

Technical Field

[0001] The invention relates to the field of grinding, and in particular to a contact type aluminum profile surface grinding device. Background Art

[0002] Grinding and polishing refers to a processing method that uses mechanical means to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. After the aluminum profile is produced, it needs to be polished. When polishing tubular aluminum profiles such as aluminum tubes, two abrasive belts are often used to clamp the aluminum tube and drive the two abrasive belts to rotate around the aluminum tube to polish the surface of the aluminum tube.

[0003] In the prior art, for example, a Chinese patent with the announcement number CN212371860U, entitled "A CNC pipe bending automatic sanding machine", discloses a technical solution in which a polishing assembly includes a polishing disc and a turntable power, wherein the polishing disc includes a sanding turntable connected to the turntable power transmission and two sanding belts rotatably arranged on the disk surface of the sanding turntable, wherein a through hole for the workpiece to pass through is arranged at the center of the sanding turntable, and the two sanding belts are respectively located on both sides of the center of the through hole. During grinding and polishing, one end of the tubular workpiece is inserted between the two sanding belts, and the two sanding belts clamp the pipe fitting and rotate to grind the pipe fitting. However, usually, the spacing between the two sanding belts is smaller than the outer diameter of the pipe fitting. When inserting the tubular workpiece between the two sanding belts, it is necessary to find a certain angle to squeeze the two sanding belts apart before inserting them. There are certain inconveniences in operation, which affects the grinding and polishing efficiency of the pipe fitting. Summary of the invention

[0004] The present invention provides a contact type aluminum profile surface grinding device to solve the above problems.

[0005] The present invention discloses a contact type aluminum profile surface grinding device, which adopts the following technical scheme: a contact type aluminum profile surface grinding device, comprising a frame and a grinding cylinder.

[0006] Rack front and rear settings.

[0007] The grinding cylinder axis is fixed on the frame in a front-to-back arrangement. A rotating ring is rotatably installed in the grinding cylinder. Two abrasive belts are symmetrically arranged on the rotating ring. The two abrasive belts are arranged in parallel. A supporting device is arranged at the front side of the grinding cylinder, and a guiding device is arranged at the rear side.

[0008] The guiding device includes a mounting plate, a main rod, a sleeve, an auxiliary component, and a limiter component. The mounting plate is rotatably mounted on the rear end of the grinding cylinder through a hinge assembly. The main rod and the grinding cylinder are coaxial and are slidably arranged on the mounting plate. The sleeve is arranged between the grinding cylinder and the mounting plate. The sleeve is sleeved on the main rod. The sleeve and the main rod are slidably matched, and the front end of the sleeve is at the rear side of the front end of the main rod. A first spring is connected between the sleeve and the main rod.

[0009] There are multiple auxiliary components arranged along the circumference of the main rod, including a front rod, a rear rod, and a clamping rod. The front rod is tilted forward and backward, with the front end close to the main rod and the rear end away from the main rod. The rear rod is arranged on the rear side of the front rod. The rear rod is tilted forward and backward, with the front end away from the main rod and the rear end close to the main rod. The front end of the front rod is rotatably connected to the front end of the main rod, and the rear end is rotatably connected to the front end of the rear rod. The rear end of the rear rod is rotatably connected to the front end of the sleeve. The clamping rod is coaxially fixed to the front end of the rear rod. The clamping rod and the front rod form a V-shape with the large end facing forward.

[0010] The limiting assembly is used to move the sleeve backward a preset distance relative to the main rod when the main rod moves forward toward the grinding cylinder, so that the front rod and the rear rod are close to the main rod, which is convenient for the auxiliary assembly to pass through the two sanding belts. When the auxiliary assembly passes through the two sanding belts, the sleeve is moved forward and reset, so that the front rod and the rear rod are away from the main rod to form a V shape with the opening facing the axis of the main rod.

[0011] Furthermore, the limiting assembly includes a limiting ring. The limiting ring is arranged between the sleeve and the mounting plate. The limiting ring is sleeved on the main rod. The limiting ring is a magnet and is connected to the mounting plate through magnetic force. A second spring is connected between the limiting ring and the sleeve.

[0012] Furthermore, a third spring is connected between the mounting plate and the main rod.

[0013] Furthermore, the hinge assembly includes a first column and a second column. The first column is arranged front and rearwardly on the rear side of the grinding cylinder. The front end of the first column is fixed to the upper end of the grinding cylinder. The rear end surface of the first column is set as the first mating surface. The second column is arranged at the rear side of the first column. The second column is arranged front and rearwardly, the front end abuts against the rear end of the first column, and the rear end is fixedly connected to the mounting plate. The front end surface of the second column is set as the second mating surface. A rotating shaft is provided between the second column and the first column. The rotating shaft is fixed to the upper end of the first mating surface. The rotating shaft and the upper end of the second mating surface are rotatably matched. When the second column rotates around the rotating shaft so that the first mating surface and the second mating surface coincide, the first column and the second column are coaxial, and the main rod and the grinding cylinder are coaxial.

[0014] Furthermore, a locking device is provided between the mounting plate and the hinge assembly. The locking device is used to drive the mounting plate to drive the main rod to rotate upward after the relative position of the main rod and the mounting plate is kept unchanged by hand after the aluminum tube is inserted between the two sanding belts, so that the second column rotates upward around the rotating axis, the main rod and the mounting plate are locked, the third spring is in a force storage state, the mounting plate drives the main rod to rotate downward, and when the main rod and the grinding cylinder are coaxial, the lock between the main rod and the mounting plate is released.

[0015] Further, the locking device includes a first locking rod, a second locking rod and a locking groove.

[0016] The first locking rod is arranged along the axis of the second column. The first locking rod is slidably installed in the second column along the axis of the second column. The end of the first locking rod close to the mounting plate is wedge-shaped, and the end away from the mounting plate extends between the first mating surface and the second mating surface.

[0017] The second locking rod is arranged radially along the main rod. The second locking rod is slidably installed in the mounting plate along the radial direction of the main rod. A wedge block is fixed to one end of the second locking rod close to the wedge-shaped end of the first locking rod. The inclined surface of the wedge block and the inclined surface of the wedge-shaped end of the first locking rod are slidably matched through the T-shaped groove and the T-shaped block. A fourth spring is connected between the wedge block and the mounting plate.

[0018] The locking groove is arranged on the side wall of the main rod. When the second column rotates upward around the rotation axis, the fourth spring drives the second locking rod box main rod to slide, so that the second locking rod is inserted into the locking groove, and the main rod is restricted from sliding relative to the mounting plate. When the second column rotates around the rotation axis so that the first mating surface and the second mating surface coincide, so that the main rod and the grinding cylinder are coaxial, the first mating surface pushes the first locking rod toward the mounting plate, drives the second locking rod to pull out of the locking groove, releases the lock between the main rod and the mounting plate, and the third spring releases the force, driving the main rod to move toward the two sanding belts.

[0019] Furthermore, a supporting device is provided on the front side of the grinding cylinder, and the supporting device is used to provide auxiliary support to the aluminum tube to be ground.

[0020] Furthermore, the supporting device comprises a supporting platform, which is movably arranged on the frame.

[0021] Furthermore, the support device also includes an adjustment component. The adjustment component is used to adjust the height of the support platform according to the diameter of the aluminum tube, so that the axis of the aluminum tube placed on the support platform is coaxial with the grinding cylinder, so that the surface of the aluminum tube is polished more evenly.

[0022] Furthermore, a mounting hole is provided on the mounting plate, and the main rod is slidably fitted in the mounting hole.

[0023] The adjusting component comprises an adjusting chamber and a hydraulic rod.

[0024] The regulating chamber is provided at the rear end of the main rod. A piston plate is slidably installed in the regulating chamber. The piston plate divides the regulating chamber into a front chamber and a rear chamber which are not connected to each other. The front chamber is connected to the outside through a locking groove. The rear chamber is filled with hydraulic oil. A plurality of push rods are provided at the rear side of the piston plate. The push rods are elastic rods. The push rods are arranged forward and backward along the axis of the main rod, the rear end is fixed on the piston plate, and a push block is fixed at the front end.

[0025] The push block is arranged at the rear side of the limit ring. The push block and the locking groove are slidably matched. The push block is wedge-shaped with the small end away from the axis of the main rod, and the front end face of the push block is perpendicular to the axis of the main rod, and the rear end face is an inclined surface. In the initial state, the small end of the push block abuts against the hole wall of the mounting hole, and the push rod is deformed so that the push block is accommodated in the locking groove.

[0026] The hydraulic rod is arranged between the support platform and the frame. The hydraulic rod is fixed on the frame, and the piston rod of the hydraulic rod is fixedly connected to the support platform. A fifth spring is connected between the hydraulic rod and the support platform. The hydraulic chamber and the rear chamber of the hydraulic rod are connected through an oil pipe. In the process of the front rod and the rear rod passing through the two sanding belts, the main rod moves toward the two sanding belts. Since the limiting ring and the mounting plate are magnetically fixed, when the main rod stretches the first spring, and due to the limiting of the second spring, the sleeve moves backward relative to the main rod, and the front rod and the rear rod are close to the main rod to facilitate the passage of the two sanding belts. At this time, the main rod pulls the sleeve to move synchronously through the front rod and the rear rod to stretch the second spring. After the push block is separated from the mounting hole and the limiting ring, it extends out of the locking groove from the locking groove in the direction away from the axis of the main rod. When the front rod and the rear rod pass through the two sanding belts, the tension of the first spring and the second spring is greater than the magnetic attraction of the limit ring on the mounting plate. The first spring and the second spring are reset to make the limit ring separate from the mounting plate and move toward the two sanding belts. When the limit ring passes through the push block, it first pushes the block into the locking groove and then moves to the front side of the push block. The push rod resets and drives the push block to extend out of the locking groove again, and the front end face of the push block abuts against the limit ring. At this time, the front rod and the rear rod are away from the main rod to form a V shape with the opening facing the axis of the main rod. One end of the aluminum tube is sleeved on the front end of the main rod and pressed against the front rod. When the aluminum tube moves backward, the aluminum tube drives the front rod to approach the main rod, and the rear rod approaches the main rod synchronously with the front rod. When the rear rod approaches the main rod, the rear rod pushes the sleeve to move backward, the sleeve pushes the push block, and the push block pushes the piston plate to move through the push rod. The piston plate presses the hydraulic oil in the rear cavity into the hydraulic rod to drive the support platform to rise and fall. When the aluminum tube abuts the clamping rod, the aluminum tube abuts the clamping rod to prevent the rear rod from further approaching the main rod, and the support platform stops lifting. At this time, the front rod and the clamping rod simultaneously abut the wall of the aluminum tube, and the distance from the intersection of the front rod and the rear rod to the axis of the main rod is the radius of the aluminum tube, so that the height of the support platform can be adjusted according to the diameter of the aluminum tube.

[0027] The beneficial effects of the present invention are as follows: when the main rod moves forward toward the grinding tube, the limit assembly causes the sleeve to move backward relative to the main rod by a preset distance, so that the front rod and the rear rod are close to the main rod, which is convenient for the auxiliary assembly to pass through the two sanding belts. When the auxiliary assembly passes through the two sanding belts, the sleeve is moved forward and reset, so that the front rod and the rear rod are away from the main rod to form a V-shape with an opening toward the axis of the main rod. One end of the aluminum tube is sleeved on the front end of the main rod and pressed against the front rod. When the aluminum tube moves backward, the aluminum tube drives the front rod to approach the main rod, and the rear rod approaches the main rod synchronously with the front rod. When the aluminum tube abuts the clamping rod, the aluminum tube abuts the clamping rod to prevent the rear rod from continuing to approach the main rod. When the aluminum tube pushes the main rod to pass through the two sanding belts through the clamping rod and the front rod, since the rear rod is in a state where the front end is away from the main rod and the rear end is close to the main rod, multiple rear rods are surrounded around the axis of the main rod to form a cone with a small end facing backward. Before the aluminum tube is inserted between the two sanding belts, the rear rod first opens the two sanding belts, which is convenient for the insertion of the aluminum tube and improves the grinding efficiency.

The push block 950 is wedge-shaped with the small end away from the axis of the main rod 300, and the front end face of the push block 950 is perpendicular to the axis of the main rod 300, and the rear end face is an inclined surface. In the initial state, the small end of the push block 950 abuts against the hole wall of the mounting hole, and the push rod 940 is deformed so that the push block 950 is received in the locking groove 840 .

[0047] The hydraulic rod 960 is arranged between the support platform 910 and the frame 100. The hydraulic rod 960 is fixed on the frame 100, and the piston rod of the hydraulic rod 960 is fixedly connected to the support platform 910. A fifth spring is connected between the hydraulic rod 960 and the support platform 910. The hydraulic chamber of the hydraulic rod 960 and the rear chamber 922 are connected through an oil pipe. In the process of the front rod 510 and the rear rod 520 passing through the two sanding belts 210, the main rod 300 moves toward the two sanding belts 210. Since the limiting ring 610 and the mounting plate 220 are magnetically fixed, when the main rod 300 stretches the first spring 410, and due to the limiting of the second spring 620, the sleeve 400 moves backward relative to the main rod 300, and the front rod 510 and the rear rod 520 are close to the main rod 300 to facilitate passing through the two sanding belts 210. At this time, the main rod 300 pulls the sleeve 400 to move synchronously through the front rod 510 and the rear rod 520, and stretches the second spring 620. After the push block 950 is separated from the mounting hole and the limit ring 610, it extends out of the locking groove 840 from the locking groove 840 in the direction away from the axis of the main rod 300. When the front rod 510 and the rear rod 520 pass through the two sand belts 210, the pulling force of the first spring 410 and the second spring 620 is greater than the magnetic attraction of the limit ring 610 on the mounting plate 220. The first spring 410 and the second spring 620 are reset to make the limit ring 610 separate from the mounting plate 220 and move toward the two sand belts 210. When the limit ring 610 passes through the push block 950, it first pushes the block into the locking groove 840 and then moves to the front side of the push block 950. The reset of the push rod 940 drives the push block 950 to extend out of the locking groove 840 again, and the front end surface of the push block 950 abuts against the limit ring 610. At this time, the front rod 510 and the rear rod 520 are away from the main rod 300 to form a V shape with the opening facing the axis of the main rod 300. One end of the aluminum tube 110 is sleeved on the front end of the main rod 300 and pressed against the front rod 510. When the aluminum tube 110 moves backward, the aluminum tube 110 drives the front rod 510 to approach the main rod 300, and the rear rod 520 approaches the main rod 300 synchronously with the front rod 510. When the rear rod 520 approaches the main rod 300, the rear rod 520 pushes the sleeve 400 to move backward, the sleeve 400 pushes the push block 950, and the push block 950 pushes the piston plate 930 to move through the push rod 940. The piston plate 930 presses the hydraulic oil in the rear cavity 922 into the hydraulic rod 960, driving the support platform 910 to rise and fall. When the aluminum tube 110 abuts against the clamping rod 530, the aluminum tube 110 abuts against the clamping rod 530 to prevent the rear rod 520 from further approaching the main rod 300, and the support platform 910 stops rising and falling. At this time, the front rod 510 and the clamping rod 530 abut against the wall of the aluminum tube 110 at the same time, and the distance from the intersection of the front rod 510 and the rear rod 520 to the axis of the main rod 300 is the radius of the aluminum tube 110, so that the height of the support platform 910 can be adjusted according to the diameter of the aluminum tube 110.

[0048] In combination with the above embodiments, the use principle and working process of the present invention are as follows: when in use, the first motor is started to drive the rotating ring to drive the sanding belt 210 to rotate.

[0049] The mounting plate 220 is rotated by hand to rotate the main rod 300 downward. When the main rod 300 and the grinding cylinder 200 are coaxial, the first mating surface 711 pushes the first locking rod 810 toward the mounting plate 220, driving the second locking rod 820 to pull out of the locking groove 840, thereby releasing the lock between the main rod 300 and the mounting plate 220, and the third spring 310 releases force, driving the main rod 300 to move toward the two sanding belts 210.

[0050] Since the limiting ring 610 and the mounting plate 220 are fixed by magnetic attraction, when the main rod 300 stretches the first spring 410, and due to the limitation of the second spring 620, the sleeve 400 moves backward relative to the main rod 300, and the front rod 510 and the rear rod 520 are close to the main rod 300 to facilitate the passage of the two abrasive belts 210. At this time, the main rod 300 pulls the sleeve 400 to move synchronously through the front rod 510 and the rear rod 520 to stretch the second spring 620. After the push block 950 is separated from the mounting hole and the limiting ring 610, it extends out of the locking groove 840 in a direction away from the axis of the main rod 300.

[0051] When the front rod 510 and the rear rod 520 pass through the two abrasive belts 210 and move to the front side of the grinding cylinder 200, the pulling force of the first spring 410 and the second spring 620 is greater than the magnetic attraction of the limit ring 610 on the mounting plate 220, and the first spring 410 and the second spring 620 are reset to make the limit ring 610 separate from the mounting plate 220 and move toward the two abrasive belts 210. When the limit ring 610 passes through the push block 950, it first pushes the block into the locking groove 840 and then moves to the front side of the push block 950. The reset of the push rod 940 drives the push block 950 to extend out of the locking groove 840 again, and the front end face of the push block 950 abuts against the limit ring 610. At this time, the front rod 510 and the rear rod 520 are away from the main rod 300 to form a V shape with the opening facing the axis of the main rod 300.

[0052] Put one end of the aluminum tube 110 on the front end of the main rod 300 and press against the front rod 510. Push the aluminum tube 110 backward by hand. When the aluminum tube 110 moves backward, the aluminum tube 110 drives the front rod 510 to approach the main rod 300, and the rear rod 520 approaches the main rod 300 synchronously with the front rod 510. When the rear rod 520 approaches the main rod 300, the rear rod 520 pushes the sleeve 400 to move backward, the sleeve 400 pushes the push block 950, and the push block 950 pushes the piston plate 930 to move through the push rod 940. The piston plate 930 presses the hydraulic oil in the rear cavity 922 into the hydraulic rod 960, driving the support platform 910 to rise and fall.

[0053] When the aluminum tube 110 abuts against the clamping rod 530, the aluminum tube 110 abuts against the clamping rod 530 to prevent the rear rod 520 from further approaching the main rod 300, and the support platform 910 stops rising and falling. At this time, the front rod 510 and the clamping rod 530 abut against the wall of the aluminum tube 110 at the same time, and the distance from the intersection of the front rod 510 and the rear rod 520 to the axis of the main rod 300 is the radius of the aluminum tube 110, so that the height of the support platform 910 can be adjusted according to the diameter of the aluminum tube 110.

[0054] Continue to push the aluminum tube 110 backward. The aluminum tube 110 pushes the main rod 300 backward through the clamping rod 530 and the front rod 510. When the aluminum tube 110 pushes the main rod 300 through the two sanding belts 210 through the clamping rod 530 and the front rod 510, the rear rod 520 is in a state where the front end is far away from the main rod 300 and the rear end is close to the main rod 300, so that the multiple rear rods 520 are formed into a cone with the small end facing backward around the axis of the main rod 300. Before the aluminum tube 110 is inserted between the two sanding belts 210, the rear rod 520 first opens the two sanding belts 210 to facilitate the insertion of the aluminum tube 110 and improve the grinding efficiency. In the process of pushing the main rod 300 backward through the aluminum tube 110, the third spring 310 is stretched to store force in the third spring 310.

[0055] After the aluminum tube 110 is inserted between the two abrasive belts 210, the limit ring 610 and the mounting plate 220 are magnetically fixed again, and the mounting hole pushes the push block 950 into the locking groove 840. At this time, after the relative position of the main rod 300 and the mounting plate 220 is kept unchanged by hand, the mounting plate 220 is driven to drive the main rod 300 to rotate upward, so that the second column 720 rotates upward around the rotation axis, the first matching surface 711 and the first locking rod 810 are out of contact, so that the fourth spring 830 releases force, drives the second locking rod 820 to move toward the main rod 300, and inserts it into the locking groove 840, locks the main rod 300 and the mounting plate 220, and puts the third spring 310 in a power storage state.

[0056] After the aluminum tube 110 is inserted between the two abrasive belts 210 , the two abrasive belts 210 rotate around the aluminum tube 110 to grind the surface of the aluminum tube 110 .

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
