Technical Field
[0001] This utility model relates to the technical field of clamping devices for guide wheel sandblasting, specifically a clamping device for guide wheel sandblasting. Background Technology
[0002] Sandblasting is a surface treatment process for workpieces. It uses compressed air to propel abrasive materials (copper ore sand, quartz sand, corundum, iron sand, sea sand) at high speed onto the surface of the workpiece, altering its appearance or shape. Due to the impact and cutting action of the abrasive on the workpiece surface, it achieves a certain level of cleanliness and varying roughness, thus improving the mechanical properties of the workpiece surface. Sandblasting is required after the production of guide wheels. In the existing sandblasting process of guide wheels, the guide wheels are held manually with the help of a clamping device. Traditional clamping devices often have problems such as unstable clamping, inaccurate positioning, and cumbersome operation, resulting in unsatisfactory sandblasting effect and even damage to parts. Therefore, we have proposed a clamping device for sandblasting guide wheels to solve the above-mentioned problems. Summary of the Invention

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-6This utility model provides a technical solution: a clamping device for sandblasting guide wheels, comprising a housing 1, a door 10 hinged to the front of the housing 1, an observation port on the surface of the door 10, a turntable 2 rotatably mounted on both sides inside the housing 1, three sets of fixing rods 3 on the front of the turntable 2, an assembly plate 4 at the front end of the fixing rods 3, a clamping assembly 5 mounted on the assembly plate 4, and a sandblasting assembly 6 mounted at the top inside the housing 1. The sandblasting assembly 6 includes a drive groove 601, a lead screw 602, a slider 603, and a sandblasting head 604. The drive groove 601 is located at the top inside the housing 1, the slider 603 slides within the drive groove 601, and the lead screw is located at the center of the drive groove 601. 602, the lead screw 602 is rotatably connected to the housing 1, the lead screw 602 is threadedly connected to the slider 603, the slider 603 is provided with a sandblasting head 604 in front, the sandblasting head 604 is connected to the external feeding system through the feed pipe, the inside of the housing 1 is provided with inclined guide plates 7 on both sides, the inside of the housing 1 is provided with a waste sand collection assembly 8 at the bottom, the waste sand collection assembly 8 includes a magnetic separation drum 801, a partition 802 and a baffle 803, the magnetic separation drum 801 is rotatably provided at the bottom of the housing 1, the partition 802 is provided at the center of the bottom of the housing 1, the baffle 803 is slidably provided on both sides of the bottom of the housing 1, and a third motor for driving the magnetic separation drum 801 is provided on the rear side wall of the housing 1; After fixing the two sets of guide wheels, the door 10 is closed via the hinge shaft to prevent sand from splashing and causing injury during sandblasting. At this point, external sand is fed through the feed pipe to the sandblasting head 604 and then ejected. Simultaneously, the second motor is started to rotate the lead screw 602, causing the lead screw 602 to move the slider 603 inside the drive groove 601. The slider 603 synchronously moves the sandblasting head 604 to sandblast the guide wheels. During sandblasting, the first motors on both sides of the box 1 are started to rotate the turntable 2, causing the three sets of fixed rods 3 on the surface of the turntable 2 to rotate synchronously. The fixed rods 3 drive the front assembly plate 4 and guide wheels to rotate, facilitating sandblasting of different positions on the guide wheel surface by the sandblasting head 604. Combined with the movement of the sandblasting head 604, the two fixed sets of guide wheels inside can be sandblasted simultaneously, processing two sets of guide wheels at once to improve efficiency. After the waste sand falls onto the inclined guide plate 7 below, it slides down through the guide plate 7 into the lower part of the box 1. The third motor is started to drive the magnetic separator drum 801. Under the action of a strong magnetic field, the metal particles are attracted to the surface of the drum. When the drum rotates to the area with a lower magnetic field strength, the metal impurities are always bound by the magnetic force, while the non-metallic particles fall directly into the left side area inside the box 1. When the metal impurities rotate to the area with the lowest magnetic field strength, the magnetic force weakens, and the particles automatically fall into the right side area inside the box 1 under the action of gravity, thus achieving complete separation of metal and non-metal impurities. The two sides inside the box 1 are separated by a partition 802 to complete the separation of sand and metal impurities. After the separation is completed, the baffles 803 on both sides of the surface of the box 1 can be pulled to remove the baffles 803 from the inside of the box 1, and the waste sand and the separated metal impurities can be collected respectively. The clamping assembly 5 includes a movable plate 501, a movable rod 502, a right-angle connecting plate 503, a movable groove 504, an adjusting plate 505, a push rod 506, and a support plate 507. The assembly plate 4 has fixing blocks 11 at its triangular positions. Both sides of the three sets of fixing blocks 11 are hinged to one end of the adjusting plate 505, and both sides of the three sets of fixing blocks 11 are hinged to the middle position of the right-angle connecting plate 503. One end of the right-angle connecting plate 503 has a movable groove 504. A cylinder 12 is located at the center of the rear side of the assembly plate 4, and the movable plate 501 is located on the front side of the assembly plate 4. The output end of the cylinder 12... After sliding through the assembly plate 4, it is connected to the rear side of the moving plate 501. The moving plate 501 has two sets of moving rods 502 that are adapted to the moving groove 504 at the triangular position. One end of the right angle connecting plate 503 is hinged to the top rod 506. The front end of the top rod 506 is hinged to one end of the adjusting plate 505. The front side of the top rod 506 is provided with a support plate 507. The front side of the three sets of support plates 507 is provided with an anti-slip layer 9. The anti-slip layer 9 is made of rubber. The two side walls of the box body 1 are provided with a first motor for driving the corresponding turntable 2. The side wall of the box body 1 is provided with a second motor for driving the lead screw 602. In use, after opening the box door 10, place the two sets of guide wheels above the three sets of support plates 507 on both sides. Then, move the moving plate 501 by the cylinder 12. The cylinder 12 is equipped with a protective shell to prevent damage to the cylinder 12 during sandblasting. At this time, the moving rods 502 on both sides of the triangular part of the moving plate 501 slide inside the moving groove 504 at one end of the right-angle connecting plate 503, driving the right-angle connecting plate 503. This causes the right-angle connecting plate 503 to be adjusted around the fixed block 11 via the hinge shaft. At the same time, one end drives the top rod 506 to move. After the top rod 506 drives the adjusting plate 505 to rotate synchronously for support, the top rod 506 further drives the support plate 507 to move, so that the rubber anti-slip layer 9 on the surface of the support plate 507 contacts the inner wall of the guide wheel. Through the synchronous contact of the three sets of support plates 507 with the inner wall of the guide wheel, the inner support and fixation of the guide wheel is completed.
[0016] Working principle: When using the guide wheel sandblasting clamping device, after opening the box door 10, place the two sets of guide wheels above the three sets of support plates 507 on both sides. Then, the cylinder 12 drives the moving plate 501 to move. The cylinder 12 is equipped with a protective shell to prevent damage to the cylinder 12 during sandblasting. At this time, the moving rods 502 on both sides of the triangular part of the moving plate 501 slide inside the moving groove 504 at one end of the right-angle connecting plate 503, driving the right-angle connecting plate 503. This causes the right-angle connecting plate 503 to be adjusted around the fixed block 11 via the hinge axis. At the same time, one end drives the top rod 506 to move. The top rod 506 drives the adjusting plate 505 to rotate synchronously for support. Then, the top rod 506 further drives the support plate 507 to move, so that the rubber anti-slip layer 9 on the surface of the support plate 507 contacts the inner wall of the guide wheel. Through the synchronous contact of the three sets of support plates 507 with the inner wall of the guide wheel, the inner support and fixation of the guide wheel is completed. After the two sets of guide wheels are fixed, the door 10 is closed by the hinge shaft to avoid sand splashing during the sandblasting process and causing personnel injury. At this time, the external sand is transported to the sandblasting head 604 through the feed pipe and sprayed out. At the same time, the second motor is started to drive the lead screw 602 to rotate, so that the lead screw 602 drives the slider 603 to move inside the drive groove 601. The slider 603 synchronously drives the sandblasting head 604 to move, sandblasting the guide wheel. During the sandblasting process, the start The first motor on each side wall of the housing 1 drives the turntable 2 to rotate, causing the three sets of fixed rods 3 on the surface of the turntable 2 to rotate synchronously. The fixed rods 3 drive the front mounting plate 4 and guide wheels to rotate, facilitating the sandblasting head 604 to sandblast different positions on the surface of the guide wheels. With the movement of the sandblasting head 604, the two sets of fixed guide wheels inside can be sandblasted synchronously, processing two sets of guide wheels at once to improve efficiency. The waste sand generated during the sandblasting process falls above the inclined guide plate 7 below and slides down the guide plate 7 to the lower part of the housing 1. The third motor is started to drive the magnetic separation drum 801. Under the action of a strong magnetic field, metal particles are adsorbed onto the surface of the drum. When the drum rotates to an area with a lower magnetic field strength, the metal impurities are... Constantly bound by magnetic force, non-metallic particles fall directly into the left side of the box 1. When metallic impurities rotate with the cylinder to the area with the lowest magnetic field strength, the magnetic force weakens, and the particles automatically fall into the right side of the box 1 under the action of gravity, achieving complete separation of metallic and non-metallic impurities. The two sides of the box 1 are separated by partitions 802 to complete the separation of sand and metallic impurities. After separation, the baffles 803 on both sides of the surface of the box 1 can be pulled to remove the baffles 803 from the inside of the box 1, and the waste sand and the separated metallic impurities can be collected respectively, thus completing a series of operations. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0017] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
