Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting fixtures, and specifically discloses a sandblasting fixture that utilizes a magnetic cap removal mechanism. Background Technology

[0002] Sandblasting is a common surface treatment process that uses high-speed jets of abrasive to impact the surface of a workpiece, achieving purposes such as cleaning, rust removal, deburring, or altering surface roughness. During sandblasting, certain areas of some products require protection to prevent unnecessary damage from the blasting process. Therefore, protective caps are typically used to cover these areas. These caps effectively isolate the blasting medium, ensuring the product maintains good surface quality after sandblasting. However, the installation and removal of these protective caps is a crucial step in the sandblasting process, and their efficiency directly impacts the efficiency of the entire production process.

[0003] In existing technologies, the installation and removal of protective caps typically rely on manual operation. Operators need to install each protective cap onto the product individually, and then remove them one by one after sandblasting is complete. However, manual installation and removal of protective caps is inefficient, especially in mass production, consuming significant time and manpower, making it difficult to improve production efficiency. Furthermore, manual operation is prone to errors; for example, if the protective cap is not securely installed or misaligned, it may fall off during sandblasting, thus affecting the sandblasting quality of the product.

[0004] Of course, existing technologies also include automated mechanical equipment, such as a four-axis rubber stopper machine disclosed in patent CN107553354A. This machine automates the process of inserting rubber stoppers into the threaded holes of products by designing X-axis modules, Y-axis modules, and on-axis modules to drive the rubber stopper picking and placing fixtures. However, such automated mechanical equipment has a complex structure, which undoubtedly greatly increases the manufacturing cost and maintenance difficulty of the equipment. Utility Model Content

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] This embodiment discloses a sandblasting fixture that utilizes a magnetic cap-removing mechanism, as shown in the following figure. Figure 1-8 It includes a base 1, a first lifting assembly, a second lifting assembly, a loading tray 6, and a protective cap 8. The surface of the loading tray 6 is provided with a plurality of loading posts 61 for placing products. The base 1 is used to position and place the loading tray 6. The first lifting assembly includes a first lifting drive 2 mounted on the base 1 with its output end facing the loading tray 6, and a mounting plate 3 mounted on the output end of the first lifting drive 2 and parallel to the loading tray 6. The bottom of the mounting plate 3 is provided with a plurality of positioning posts 32 corresponding one-to-one with the loading posts 61. The second lifting assembly includes a second lifting drive 4 mounted on the mounting plate 3 with its output end facing the loading tray 6, and a lower pressure plate 5 mounted on the output end of the second lifting drive 4 and parallel to the mounting plate 3. The lower pressure plate 5 is provided with a plurality of openings for the positioning posts 32 to pass through downwards. (Refer to...) Figure 5The protective cap 8 has an upper slot and a lower slot at its top and bottom, respectively. The lower slot can cover the product 7 on the loading column 61, protecting the parts of the product 7 that do not require sandblasting. The upper slot allows the positioning post 32 to be inserted. The protective cap 8 has a built-in magnetic attractant 81, and the positioning post 32 is a magnetic attractant that is magnetically attracted to the magnetic attractant 81. This solution utilizes the magnetic force between the built-in magnetic attractant 81 and the positioning post 32 to quickly and accurately attract and fix the protective cap 8 onto the product 7 on the loading column 61. At the same time, the automatic installation and removal of the protective cap 8 is achieved through the coordinated action of the first lifting component and the second lifting component. This process not only greatly shortens the capping time but also avoids errors caused by manual operation, ensuring the stability and consistency of the installation of the protective cap 8. Automated operation reduces repetitive labor for operators, lowers labor intensity, and improves production efficiency. It is especially suitable for sandblasting of mass-produced products and has significant economic and social benefits.

[0018] In this embodiment, both the first lifting drive component 2 and the second lifting drive component 4 are cylinders. A gantry frame 11 is provided on the base 1, and the first lifting drive component 2 is mounted on the gantry frame 11. As a preferred embodiment, the top of the mounting plate 3 is provided with a first guide post 31, and the gantry frame 11 has holes for the first guide post 31 to pass through. The top of the lower pressure plate 5 is provided with a second guide post 51, and the mounting plate 3 has holes for the second guide post 51 to pass through. The first guide post 31 and the second guide post 51 improve the stability and accuracy of the lifting process, ensuring precise alignment between the positioning post 32 and the protective cap 8, and preventing cap installation failure or damage to the product 7 due to positional deviation.

[0019] In this embodiment, the positioning post 32 is a magnet; in other embodiments, it can also be an electromagnet. The electromagnet can control the attraction and release of the protective cap 8. When the mounting plate 3 and the lower pressure plate 5 are separated, the lower pressure plate 5 not only helps the protective cap 8 to detach from the positioning post 32, but also stabilizes the protective cap 8 to prevent it from falling off the product 7 due to vibration.

[0020] As a preferred option, refer to Figure 3 The base 1 is provided with a positioning groove 101, in which the loading tray 6 is positioned. The design of the positioning groove 101 can ensure the stable placement of the loading tray 6 on the base 1, improve the positional accuracy between the loading tray 6 and the lifting component, avoid loading failure or product damage caused by the positional deviation of the loading tray 6, and thus ensure the overall operational stability of the sandblasting fixture.

[0021] As a preferred embodiment, the loading tray 6 is equipped with a limiting post 62. The top surface of the limiting post 62 is flush with the top surface of the protective cap 8 placed on the product 7. The limiting post 62 is used to contact the bottom surface of the lower pressure plate 5 for limiting. The design of the limiting post 62 can effectively control the descent position of the lower pressure plate 5, preventing excessive pressure from the lower pressure plate 5 that could damage the protective cap 8 or the product 7. At the same time, it ensures that the protective cap 8 can be accurately attracted and pulled out by the positioning post 32, improving the reliability and service life of the fixture.

[0022] As a preferred option, refer to Figure 1 The loading column 61 includes a base column 611 and a top column 612 mounted on the base column 611. A placement step is formed between the base column 611 and the top column 612. The product 7 passes through the top column 612 and is placed on the placement step. The protective cap 8 passes through the top column 612 and is placed on the product 7. This structural design ensures the stable placement of the product 7 on the loading column 61 and provides a suitable installation position for the protective cap 8. It also facilitates the installation and removal of the protective cap 8, improving operational convenience.

[0023] The process of using the magnetic cap-removing sandblasting fixture in this solution is as follows: (1) Reference Figure 1 and Figure 4 Before using the fixture for the first time, manually insert the protective caps 8 one by one onto the product 7 of the loading column 61 of the loading tray 6, and then position the loading tray 6 with the protective caps 8 installed in the positioning groove 101 of the base 1. (2) Reference Figure 5 The first lifting drive component 2 is activated to descend until the lower pressure plate 5 contacts the limiting post 62. At this time, the positioning post 32 is inserted into the upper slot of the protective cap 8, and the magnetic suction component 81 of the protective cap 8 and the positioning post 32 are magnetically attracted to each other. (3) Reference Figure 6 The first lifting drive component 2 is activated to rise, causing the protective cap 8 to move upward with the positioning column 32 and leave the product 7, thus completing the initial positioning of each protective cap 8. (4) Reference Figure 5 Replace the loading tray 6 containing the product to be sandblasted 7 onto the base 1, and start the first lifting drive component 2 to descend, so that the magnetic suction under the protective caps 8 under each positioning post 32 presses onto each product to be sandblasted 7 on the loading tray 6. (5) Reference Figure 7 The second lifting drive component 4 is activated and rises. At this time, the mounting plate 3 rises, while the lower pressure plate 5 remains in the position of pressing the protective cap 8, thereby causing the positioning column 32 to move upward and disengage from the magnetic attraction of the protective cap 8, and the protective cap 8 is left on the product 7 to be sandblasted. 6) Reference Figure 4 and Figure 8The first lifting drive component 2 is activated and moves upward until the mounting plate 3 contacts the lower pressure plate 5 at the initial position. The positioning post 32 protrudes from the bottom surface of the lower pressure plate 5, and the loading tray 6 with the protective cap 8 can be removed from the base 1. This completes one round of capping process for the entire loading tray 6 product 7, which facilitates the subsequent sandblasting process of product 7. The protective cap 8 protects the parts of product 7 that do not need to be sandblasted. 7) Reference Figure 4-6 After the product sandblasting is completed, the loading tray 6 containing the sandblasted product 7 is repositioned and placed on the base 1. The first lifting drive 2 is started to move down until the positioning column 32 magnetically attracts the protective cap 8. Then the first lifting drive 2 is started to move up, so that the protective cap 8 can be removed from the sandblasted product 7 for repeated use. 8) In the next round of capping, there is no need to manually place the protective cap again. Instead, simply repeat steps (4) to (7).
