Description

Technical Field

[0001] This invention relates to the field of sandblasting technology, specifically to a magnetic chuck fixture for sandblasting. Background Technology

[0002] Sandblasting is a surface treatment process for workpieces. It uses compressed air to propel abrasive particles at high speed onto the workpiece surface, altering its appearance or shape. Due to the impact and cutting action of the abrasive particles, the workpiece surface achieves a certain level of cleanliness and varying roughness, improving its mechanical properties. This enhances the workpiece's fatigue resistance, increases adhesion between the workpiece and coatings, extends coating durability, and also facilitates paint leveling and finishing.

[0003] Current sandblasting magnetic chuck fixtures, using ordinary iron frame sandblasting fixtures, are prone to product shaking and damage / deformation due to the small size of the workpiece and excessive sandblasting pressure. Furthermore, a significant amount of abrasive is wasted during the sandblasting process. Summary of the Invention

A locking rod is fixedly connected to the bottom of the sleeve, and the locking rod engages with the slot.

[0016] Preferably, a back plate is fixedly connected to the top of the top plate, and a protective plate is fixedly connected to the outside of the back plate. The protective plate is arc-shaped, and there are two protective plates.

[0017] This invention provides a magnetic chuck fixture for sandblasting. It has the following advantages:

[0018] 1. This sandblasting magnetic chuck fixture, through the inclusion of a connecting mechanism, a control mechanism, and a steering mechanism, addresses the common problems associated with ordinary iron frame sandblasting fixtures. These problems arise because small workpieces and excessive sandblasting pressure can easily cause product wobbling and damage. Magnetic blocks are used to attract and fix the workpiece to the top of the magnetic blocks, with a distance between the blocks to solve these issues. Furthermore, significant abrasive waste occurs during sandblasting, which is difficult to collect. Therefore, the connecting, control, and steering mechanisms strengthen the fixation between the magnetic blocks and the rotating sandblasting disc, ensuring the magnetic blocks adhere to the rotating disc and the abrasive falls more accurately onto the workpiece. A sleeve with an adhesive outer shell collects and adheres the abrasive that falls around the workpiece, reducing waste and thus solving the aforementioned problems. This design facilitates the use of magnetic blocks to fix the workpiece.

[0019] 2. This sandblasting magnetic chuck fixture, through the addition of a control mechanism, addresses the issue that using ordinary fixtures to clamp or hold small workpieces is time-consuming, and leaves a large amount of residual sand at the clamping or holding points. This can lead to uneven sandblasting or sand clogging the clamping or holding points, making disassembly difficult. Therefore, a control mechanism is implemented to attract and fix the small workpiece onto the magnetic block, and the fixation is monitored to resolve these problems. With the steering mechanism in its natural state, the workpiece is placed in the groove at the top of the magnetic block. Moving the magnetic block up and down causes the first spring to drive the lifting frame upwards to strike the magnetic block, checking whether the workpiece is properly placed and whether the attraction is stable. After sandblasting, after collecting the workpiece, the magnetic block can be moved up and down again, causing the first spring to drive the lifting frame upwards to strike the magnetic block, checking for any remaining sand in the groove at the top of the magnetic block to prevent interference with the fixation of subsequent workpieces. This facilitates impact testing of the magnetic block.

[0020] 3. This sandblasting magnetic chuck fixture, through the inclusion of an adjustment component, allows the second spring and sliding plate to move outwards during manual adjustment of the steering mechanism. Simultaneously, the elastic band gradually stretches, driving the positioning plate towards the fixed frame. This prevents the positioning plate from being at the same height as the curved suction plate, which could affect the flatness of the magnetic block's bottom and consequently its fixation. Furthermore, the inclusion of a fixing semi-ring prevents the second spring from falling downwards upon returning to its original position, thus preventing the sliding plate from returning to its original position and affecting the position of the elastic band and positioning plate. This achieves the goal of facilitating a flat bottom for the magnetic block.

[0021] 4. This sandblasting magnetic chuck fixture, through the setting of a steering mechanism, has a detachable top plate installed around the perimeter of the magnetic block. A detachable sleeve with an adhesive outer shell is installed on top of the top plate. In the absence of wind, this sleeve collects and adheres to a large amount of residual sand generated during the sandblasting process, reducing sand waste. Simultaneously, after the sleeve is removed, airflow can be used to clean the top of the magnetic block, preventing residual sand from remaining in the grooves. This achieves the goal of easily reducing sand waste. Attached Figure Description

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0032] like Figures 1-8 As shown, the present invention provides a technical solution, specifically including:

[0033] Magnetic block 1, with a groove 3 on the upper surface of magnetic block 1, a copper strip 7 fixedly connected to the top of magnetic block 1, and a hexagonal groove 4 inside magnetic block 1;

[0034] The connecting mechanism 2 includes an arc-shaped suction plate 201. A fixed frame 202 is fixedly connected to the outside of the arc-shaped suction plate 201. A locking plate 203 is engaged inside the fixed frame 202. An elastic band is fixedly connected to the outside of the locking plate 203. Four elastic bands are provided. The arc-shaped suction plate 201 is fixedly connected to the bottom of the magnetic block 1.

[0035] The control mechanism 5 is used to control the workpiece to detach from the magnetic block 1. The control mechanism 5 includes a sliding column 501 and an adjustment component 507. A circular plate 502 is fixedly connected to the top of the sliding column 501, and a first suction cup 503 is fixedly connected to the bottom of the circular plate 502. The sliding column 501 is fixedly connected to the top of the positioning plate 203. The control component is fixedly connected to the outside of the fixed frame 202. A steering mechanism 6 is fixedly connected to the outside of the adjustment component 507.

[0036] The groove 3 has several openings, the arc-shaped suction plate 201 has four openings, the hexagonal groove 4 has a hexagonal key that is engaged inside, the bottom of the magnetic block 1 has a channel, and the first suction cup 503 has four openings.

[0037] Before using the equipment, manually adjust the control mechanism 5, and then adjust the position of the steering mechanism 6. Place the magnetic block 1 on the worktable and manually place all workpieces on the groove 3 on top of the magnetic block 1, maintaining a distance between them. Then, manually engage the hexagonal key in the hexagonal slot 4. At this point, the magnetic block 1 becomes magnetic, and the workpieces are attracted and fixed in the groove 3. Manually move the position of the magnetic block 1 to bring it onto the rotating sandblasting disc. Manually adjust the control mechanism 5, and then adjust the direction of the steering mechanism 6 to fix the magnetic block 1 on the rotating sandblasting disc, while protecting one circumference of the magnetic block 1. After starting the sandblasting equipment, as the rotating sandblasting disc rotates, the magnetic block 1 rotates accordingly, beginning the uniform sandblasting of the workpieces. Manually remove the hexagonal key; at this point, the magnetic block 1 loses its magnetism, allowing for uniform collection of the workpieces. Activate the steering mechanism 6 to treat the surface of the magnetic block 1.

[0038] A sliding top plate 504 is fixedly connected to the top of the circular plate 502. A first spring 505 is fixedly connected to the top of the sliding top plate 504. Four first springs 505 are provided. A lifting frame 506 is fixedly connected to the top of the first springs 505. A rubber shell is fitted over the lifting frame 506.

[0039] When the rotating mechanism is in its natural state, when the magnetic block 1 is manually lifted, the locking plate 203, sliding column 501, circular plate 502, sliding top plate 504, first spring 505, and lifting frame 506 will slide downwards under their own weight until the suction cup at the bottom of the circular plate 502 is attracted and fixed to the bottom of the magnetic block 1. When the magnetic block 1 is manually placed on the worktable, the locking plate 203 and the arc-shaped suction plate 201 fall onto the worktable together. During this process, the locking plate 203, sliding column 501, circular plate 502, sliding top plate 504, first spring 505, and lifting frame 506 begin to move upwards until the locking plate 203 is locked in the fixed frame 202. During the upward movement of the first spring 505, it will collide with the top of the magnetic block 1 multiple times.

[0040] The adjustment assembly 507 includes a sliding frame 5071, a second spring 5074 is fixedly connected inside the sliding frame 5071, a sliding plate 5072 is fixedly connected outside the second spring 5074, an elastic band is fixedly connected to the bottom of the sliding plate 5072 by a fixing rod 601, the sliding plate 5072 is slidably connected inside the fixing frame 202, four sliding frames 5071 are provided, and the sliding frames 5071 are fixedly connected to the outside of the fixing frame 202.

[0041] The sliding frame 5071 is externally fixedly connected to a fixed half-ring 5075, and multiple fixed half-rings 5075 are provided. The sliding plate 5072 is internally rotatably connected to a rotating shaft 5073.

[0042] As the user manually adjusts the position of the steering mechanism 6 so that it is locked outside the magnetic block 1, the rotating shaft 5073, the sliding plate 5072 and the second spring 5074 are pulled outward until the position of the steering mechanism 6 is fixed. During this process, the elastic band is stretched to its maximum length. Driven by the elastic band, the locking plate 203 is gradually moved to the same horizontal height as the sliding plate 5072 and gradually locked back into the interior of the fixing frame 202, making the bottom flat.

[0043] As the user manually adjusts the position of the steering mechanism 6, and the steering mechanism 6 is in its natural state, the rotating shaft 5073, the sliding plate 5072 and the second spring 5074 gradually return to their initial positions. At this time, the fixed half ring 5075 is used to protect the second spring 5074 and prevent the second spring 5074 from being squeezed outward. The elastic band gradually returns to its original length and no longer restricts the position of the locking plate 203.

[0044] The steering mechanism 6 includes four fixed rods 601. An adjusting rod 602 is fixedly connected to the bottom of each fixed rod 601. There are two adjusting rods 602. A clamping plate 603 is fixedly connected to the bottom of each adjusting rod 602. A second suction cup is fixedly connected to the top of the clamping plate 603. The bottom of the clamping plate 603 is arc-shaped. The fixed rods 601 are fixedly connected to the outside of the rotating shaft 5073.

[0045] Manually pull and rotate the fixing rod 601 located outside the rotating shaft 5073, so that the fixing rod 601 is locked outside the magnetic block 1, and the adjusting rod 602 is positioned below. Manually adjust the length of the adjusting rod 602 so that the clamping plate 603 is locked at the bottom of the rotating sandblasting disc, and the second suction cup is attracted and fixed at the bottom of the rotating sandblasting disc. The height of the clamping plate 603 is lower than the arc-shaped suction plate 201, so that the magnetic block 1 can be placed stably.

[0046] The top of the fixing rod 601 is engaged with the top plate 604, the top of the top plate 604 is fixedly connected to the fixing box 605, the inside of the fixing box 605 is fixedly connected to the pump body, and the inside of the fixing box 605 is provided with ventilation openings 609, and multiple ventilation openings 609 are provided.

[0047] A rubber pad 606 is fixedly connected to the top of the top plate 604, and a baffle 608 is fixedly connected to the top of the rubber pad 606. The baffle 608 is set in a right angle shape, and multiple baffles 608 are provided.

[0048] The top of the fixed box 605 is fixedly connected to a fixed cylinder 607. Multiple fixed cylinders 607 are provided. The inside of the fixed cylinder 607 is provided with a slot 610. The outside of the fixed cylinder 607 is fitted with a sleeve 611. The top of the sleeve 611 is fixedly connected to a handle 612. The outside of the sleeve 611 is fitted with an adhesive shell. The bottom of the sleeve 611 is fixedly connected to a locking rod, which engages with the slot 610.

[0049] A back plate 613 is fixedly connected to the top of the top plate 604, and a protective plate 614 is fixedly connected to the outside of the back plate 613. The protective plate 614 is arc-shaped, and both ends of the protective plate 614 are magnetic. There are two protective plates 614.

[0050] After the position of the adjusting rod 602 is fixed, the top plate 604 is manually engaged with the top of the fixing rod 601. At this time, the four top plates 604 are in the circumference of the magnetic plate. Then, the multiple sleeves 611 with adhesive outer shells are manually fitted onto the outside of the fixing cylinder 607 until the locking rod at the bottom of the sleeve 611 engages with the locking groove 610 at the top of the fixing cylinder 607. During this process, the sleeves 611 press down on the baffle 608 and the rubber pad 606, and the baffle 608 gradually blocks the position of the vent 609. During sandblasting, most of the excess sand is sprayed onto the adhesive outer shell of the sleeve 611, or falls onto the top plate 604 and the protective plate 614, with some rebounding back to the top of the magnetic plate.

[0051] After sandblasting is completed and the workpiece is collected, manually collect the adhesive outer shell of the sleeve 611 to remove excess sand. When the sleeve 611 leaves the fixed cylinder 607, the rubber pad 606 slowly returns to its original shape. The rubber pad 606 drives the baffle 608 to move upward until the vent 609 is exposed, and the worker leaves the site. Turn on the pump, and the gas moves through the vent 609 towards the magnetic plate, causing the sand on the surface of the magnetic plate to move and detach from the magnetic plate.

[0052] Working principle: Before using the equipment, manually adjust the control mechanism 5, and then adjust the position of the steering mechanism 6. Manually pull and rotate the fixed rod 601 located outside the rotating shaft 5073, so that the fixed rod 601 is locked outside the magnetic block 1, and the adjusting rod 602 is positioned below. Manually adjust the length of the adjusting rod 602 so that the clamping plate 603 is locked at the bottom of the rotating sandblasting disc, and the second suction cup is attracted and fixed at the bottom of the rotating sandblasting disc. The height of the clamping plate 603 is lower than the arc-shaped suction plate 201, and the magnetic block 1 can be placed stably. As the user manually adjusts the position of the steering mechanism 6, so that the fixed rod 601 is locked outside the magnetic block 1, the rotating shaft 5073, the sliding plate 5072 and the second spring 5074 are pulled outward until the position of the steering mechanism 6 is fixed. During this process, the elastic band is stretched to its maximum length. Under the drive of the elastic band, the clamping plate 203 is gradually moved to the same horizontal height as the sliding plate 5072, and gradually locked back into the interior of the fixed frame 202, making the bottom flat.

[0053] Place the magnetic block 1 on the workbench and manually place all the workpieces into the groove 3 on the top of the magnetic block 1, with a distance between the workpieces.

[0054] Subsequently, manually engage the hexagonal key in the hexagonal slot 4. At this point, the magnetic block 1 becomes magnetic, and the workpiece is attracted and fixed in the groove 3. Manually adjust the length of the adjusting rod 602 downwards and manually move the position of the magnetic block 1 to bring the magnetic block 1 onto the rotating sandblasting disc. Adjust the length of the adjusting rod 602 again so that the second suction cup on the top of the clamping plate 603 is attracted and fixed to the bottom of the rotating sandblasting disc. Manually engage the top plate 604 on the top of the fixing rod 601. At this point, the four top plates 604 are around the magnetic plate. Manually place the multiple sleeves 611 with adhesive outer shells onto the outside of the fixing cylinder 607 until the locking rod at the bottom of the sleeve 611 engages with the locking groove 610 at the top of the fixing cylinder 607. During this process, the sleeves 611 press down on the baffle 608 and the rubber pad 606, and the baffle 608 gradually blocks the position of the vent 609.

[0055] After the sandblasting equipment is turned on, the magnetic block 1 rotates along with the rotating sandblasting disc, and begins to uniformly sandblast the workpiece. During the sandblasting process, most of the excess sand is sprayed onto the adhesive outer shell of the sleeve 611, or falls onto the top plate 604 and the protective plate 614, and some bounces back to the top of the magnetic plate.

[0056] Manually remove the hexagonal key; at this point, magnetic block 1 loses its magnetism, allowing for the unified collection of workpieces. After sandblasting is complete and the workpieces are collected, manually collect the adhesive outer shell of sleeve 611 to gather excess sand. When sleeve 611 leaves fixed cylinder 607, rubber pad 606 slowly returns to its original shape, causing baffle 608 to move upwards until vent 609 is exposed, at which point the worker leaves the site. Turn on the pump; gas moves through vent 609 towards the magnetic plate, causing sand on the surface of the magnetic plate to move and detach from it.

[0057] When the magnetic block 1 is manually lifted, the locking plate 203, sliding column 501, circular plate 502, sliding top plate 504, first spring 505, and lifting frame 506 will slide downwards under their own weight until the suction cup at the bottom of the circular plate 502 is attracted and fixed to the bottom of the magnetic block 1. When the magnetic block 1 is manually placed on the worktable, the locking plate 203 and the arc-shaped suction plate 201 fall onto the worktable together. During this process, the locking plate 203, sliding column 501, circular plate 502, sliding top plate 504, first spring 505, and lifting frame 506 begin to move upwards until the locking plate 203 is locked in the fixed frame 202. During the upward movement of the first spring 505, it will collide with the top of the magnetic block 1 multiple times. At this time, the workpiece collection is completed, which can promote the vibration of the particles attached inside the groove 3.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
