Description

Technical Field

[0001] This utility model relates to the field of sandblasting tooling technology, specifically to a sandblasting tooling. Background Technology

[0002] In the fields of machining, hardware manufacturing, and aerospace, sandblasting is a commonly used surface pretreatment method. It mainly uses high-speed jetting of particulate matter to treat the surface of the workpiece, thereby removing impurities, cleaning the surface, improving surface roughness, or improving coating adhesion.

[0003] Existing sandblasting fixtures are mostly suitable for fixed sandblasting of medium and large workpieces. For small workpieces, different models need to be manufactured according to different fixtures, resulting in poor adaptability and low spraying efficiency. Utility Model Content

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides a sandblasting fixture with the advantages of good workpiece compatibility and high sandblasting efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sandblasting fixture for fixing a product includes a base and multiple fixing units. The fixing units are fixed on the base. Each fixing unit includes a bracket and multiple limiting members. The bracket is fixed on the base, and the limiting members protrude from the bracket. The multiple limiting members limit the bracket to form an installation space, and the product is fixed within the installation space.

[0007] Multiple limiting components fix the product to be processed within the installation space, ensuring that the product will not fall off or flip over during sandblasting, thus improving the stability of the sandblasting process. At the same time, due to the large installation space, it can accommodate products of various sizes, making it highly adaptable.

[0008] Optionally, the base includes a mounting plate and a plurality of mounting units arranged around the central axis of the mounting plate, wherein the mounting units and the fixing units correspond one-to-one, and the fixing units are disposed on the mounting units.

[0009] The fixing unit is fixed to the mounting plate by the mounting unit, which allows multiple products to be sandblasted in sequence, thus improving sandblasting efficiency.

[0010] Optionally, the mounting unit includes a first mounting rod and a second mounting rod, a first end of the second mounting rod is fixedly connected to the bottom of the bracket, a second end of the second mounting rod is fixedly connected to one end of the first mounting rod, and the other end of the first mounting rod is fixedly connected to the mounting plate, with an included angle between the first mounting rod and the second mounting rod.

[0011] The first and second mounting rods are used to fix the fixing unit to the mounting plate and ensure that there is a gap between the fixing unit and the mounting plate, so that multiple fixing units can be installed on one mounting plate, thereby increasing the number of fixing units on the mounting plate and increasing the number of processes that can be completed in a single sandblasting.

[0012] Optionally, the bracket includes a first support rod and a plurality of second support rods. The first support rod is arranged along a first direction, and the second support rods are arranged along a second direction, forming an angle between the first direction and the second direction. The plurality of second support rods are respectively arranged on opposite sides of the first support rod and are fixedly connected to the first support rod. The plurality of second support rods on the same side are spaced apart.

[0013] The first and second support rods are connected at an intersection to form a fishbone-shaped bracket that can support the product. The cross-bracing design also reduces the material used in a single fixing unit, thus lowering costs.

[0014] Optionally, the first support rod is provided with the limiting member at both ends, and each second support rod is provided with the limiting member at the end away from the first support rod.

[0015] Limiting elements are provided on the outer side of the first and second support rods. These limiting elements are used to form a surrounding enclosure to prevent the product from falling off during processing.

[0016] Optionally, the gap between adjacent second support rods forms a flow guide, which extends through the support along the thickness direction of the support.

[0017] The guide port is used to accommodate the discharge of the blasting medium during the sandblasting process, guiding the blasting medium to disperse from the bottom of the support after contacting the product, preventing reflection on the support and avoiding environmental pollution.

[0018] Optionally, the second mounting rod forms an angle with the bracket, and the second mounting rod is completely blocked by the bracket.

[0019] The second mounting rod is located within the projection range of the bracket, so that the sandblasting medium will not be sprayed onto the second mounting rod during the sandblasting process. This avoids the sandblasting medium from colliding with the second mounting rod after being sprayed and then scattering in all directions, reducing the difficulty of cleaning the sandblasting medium after processing and lowering the cleaning cost.

[0020] Optionally, the fixing position of the second mounting rod and the bracket is located at the fixing center of the bracket, and the fixing center is located at the midpoint of the fixing positions of the first support rod and the plurality of second support rods.

[0021] The second mounting rod is fixed to the bracket at the bottom center of the bracket. The second mounting rod provides good support to the bracket, distributes the force evenly, and improves the installation stability of the bracket.

[0022] Optionally, the second mounting rod and the bracket are detachably connected. The detachable connection and fixation of the second mounting rod to the bracket offers advantages such as convenient bracket installation and easy replacement and maintenance.

[0023] Optionally, the mounting plate is further provided with a mounting unit and a fixing unit, the mounting unit being located at the center of the mounting plate, and the fixing unit being fixed to the mounting unit.

[0024] After the mounting plate is equipped with fixing units on the periphery, an additional empty space will be formed in the center of the mounting plate. By reasonably arranging and adjusting the size of the fixing units, an additional fixing unit can be set on the top of the mounting plate, which can increase the number of products that can be processed during the sandblasting process and improve the sandblasting efficiency.

[0025] These features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. The preferred embodiments or means of this utility model will be shown in detail in conjunction with the accompanying drawings, but are not intended to limit the technical solutions of this utility model.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0031] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0032] like Figures 1-2 As shown, a sandblasting fixture for fixing a product includes a base 1 and multiple fixing units 2. The fixing units 2 are fixed on the base 1. Each fixing unit 2 includes a bracket 21 and multiple limiting members 22. The bracket 21 is fixed on the base 1, and the limiting members 22 protrude from the bracket 21. The multiple limiting members 22 and the bracket 21 limit each other to form an installation space, and the product is fixed in the installation space.

[0033] In this embodiment, the number of fixed units 2 is not specifically limited, and the number of fixed units 2 can be adjusted according to specific needs.

[0034] In this embodiment, the form in which the product is fixed within the installation space is not specifically limited. When the product to be processed is large, its edges can be engaged and fixed with the limiting member 22 to prevent the product from falling off or flipping during sandblasting. Because the spraying medium generates a high-speed impact on the product's contact surface, larger products have a larger surface area subjected to the impact of the spraying medium, which may cause them to move or tilt due to uneven airflow. By engaging and fixing the workpiece edges with the limiting member 22, such sliding or tilting can be effectively prevented, maintaining the correct position and angle of the workpiece.

[0035] In this embodiment, there are eight fixing units 2, which are evenly distributed around the mounting plate 11, and the angle between the lines connecting adjacent fixing units 2 and the mounting plate 11 is 45 degrees.

[0036] Multiple limiting components 22 fix the product to be processed within the installation space, ensuring that the product will not fall off or flip over during sandblasting, thus improving the stability of the sandblasting process. At the same time, due to the large installation space, it can accommodate products of various sizes, making it highly adaptable.

[0037] like Figures 1-2As shown, the base 1 includes a mounting plate 11 and a plurality of mounting units 12 arranged around the central axis of the mounting plate 11. The mounting units 12 and the fixing units 2 correspond one-to-one, and the fixing units 2 are disposed on the mounting units 12.

[0038] In actual processing, the blasting medium not only impacts the product with airflow but also the tooling itself. Therefore, designing a centrally symmetrical or axisily symmetrical fixing unit 2 ensures uniform force distribution on the sandblasting tooling. In this embodiment, the mounting unit 12 is arranged around the central axis of the mounting plate 11, ensuring the balance of the base 1. Arranging it around the central axis ensures uniform weight distribution, contributing to improved system stability and accuracy. It should be noted that in other embodiments, the mounting unit 12 and fixing unit 2 may not be designed symmetrically. Adjusting the blasting medium's spray speed can prevent tilting of the sandblasting tooling due to uneven force distribution, ensuring product processing quality.

[0039] The fixing unit 2 is fixed to the mounting plate 11 by the mounting unit 12, so that multiple products can be sandblasted in sequence, thereby improving the sandblasting efficiency.

[0040] like Figures 1-2 As shown, the mounting unit 12 includes a first mounting rod 121 and a second mounting rod 122. The first end of the second mounting rod 122 is fixedly connected to the bottom of the bracket 21, the second end of the second mounting rod 122 is fixedly connected to one end of the first mounting rod 121, and the other end of the first mounting rod 121 is fixedly connected to the mounting plate 11. An angle is formed between the first mounting rod 121 and the second mounting rod 122.

[0041] In this embodiment, the included angle between the first mounting rod 121 and the second mounting rod 122 is 90 degrees.

[0042] The first mounting rod 121 and the second mounting rod 122 are used to fix the fixing unit 2 on the mounting plate 11 and ensure that there is a gap between the fixing unit 2 and the mounting plate 11, so as to ensure that multiple fixing units 2 can be installed on one mounting plate 11, thereby increasing the number of fixing units 2 on the mounting plate 11 and increasing the number of processes that can be completed in a single sandblasting.

[0043] like Figures 1-2As shown, the bracket 21 includes a first support rod 211 and a plurality of second support rods 212. The first support rod 211 is arranged along a first direction, and the second support rods 212 are arranged along a second direction. An angle is formed between the first direction and the second direction. The plurality of second support rods 212 are respectively arranged on opposite sides of the first support rod 211 and are fixedly connected to the first support rod 211. The plurality of second support rods 212 on the same side are spaced apart.

[0044] In this embodiment, the angle between the first direction and the second direction is 90 degrees.

[0045] The first support rod 211 and the second support rod 212 are cross-connected to form a fishbone-shaped bracket 21, which can support the product. The cross-connection reduces the material used in a single fixing unit 2, thus reducing costs.

[0046] like Figures 1-2 As shown, the first support rod 211 is provided with the limiting member 22 at both ends, and each second support rod 212 is provided with the limiting member 22 at the end away from the first support rod 211.

[0047] In this embodiment, the limiting member 22 is positioned close to the outer side of the bracket 21, which provides a larger installation space, is compatible with more types of processed products, and improves the adaptability of this tooling.

[0048] A limiting member 22 is provided on the outer side of the first support rod 211 and the second support rod 212. The limiting member 22 is used to form a surrounding enclosure to prevent the product from falling off during processing.

[0049] like Figures 1-2 As shown, the interval between adjacent second support rods 212 forms a flow guide 213, which penetrates the support 21 along the thickness direction of the support 21.

[0050] The guide port 213 is used to accommodate the discharge of the sandblasting medium during the sandblasting process, and guides the sandblasting medium to disperse from the bottom of the bracket 21 after contacting the product, preventing reflection on the bracket and avoiding environmental pollution.

[0051] like Figures 1-2 As shown, the second mounting rod 122 forms an angle with the bracket 21, and the second mounting rod 122 is completely blocked by the bracket 21.

[0052] In this embodiment, the extension direction of the second mounting rod 122 is the same as the spray direction of the sandblasting.

[0053] The second mounting rod 122 is located within the projection range of the bracket 21, so that during the sandblasting process, the sandblasting medium will not be sprayed onto the second mounting rod 122, thereby avoiding the sandblasting medium from colliding with the second mounting rod 122 after being sprayed and scattering in all directions, reducing the difficulty of cleaning the sandblasting medium after processing, and lowering the cleaning cost.

[0054] In this embodiment, the included angle between the second mounting rod 122 and the bracket 21 is 90 degrees.

[0055] like Figures 1-2 As shown, the fixed position of the second mounting rod 122 and the bracket 21 is located at the fixed center of the bracket 21, and the fixed center is located at the midpoint of the fixed positions of the first support rod 211 and the plurality of second support rods 211.

[0056] In this embodiment, the fixed center is also the center of gravity of the bracket 21. The second mounting rod 122 is supported on the center of gravity of the bracket 21, which can prevent the bracket 21 from actively shifting and avoid tilting during the sandblasting process.

[0057] The second mounting rod 122 is fixed to the bracket 21 at the bottom center of the bracket 21. The second mounting rod 122 provides good support for the bracket 21, distributes the force evenly, and improves the installation stability of the bracket 21.

[0058] like Figures 1-2 As shown, the second mounting rod 122 and the bracket 21 are detachably connected. The second mounting rod 122 is detachably connected and fixed to the bracket 21, which has the advantages of convenient installation of the bracket 21 and convenient replacement and maintenance.

[0059] The detachable connection between the second mounting rod 122 and the bracket 21 can be a sleeve connection, a snap-fit ​​connection, a threaded connection, or a fixed connection by fasteners such as bolts and nuts.

[0060] In this embodiment, the second mounting rod 122 and the bracket 21 are detachably connected by bolts. The bolt and nut are used to fix the bracket 21 on the second mounting rod 122, and it is convenient to disassemble and assemble the bracket 21. It has the advantage of easy disassembly and assembly when it is necessary to change the number of fixing units 2 on the mounting plate 11.

[0061] like Figures 1-2 As shown, the mounting plate 11 is also provided with a mounting unit 12 and a fixing unit 2. The mounting unit 12 is located at the center of the mounting plate 11, and the fixing unit 2 is fixed on the mounting unit 12.

[0062] After the mounting plate 11 is equipped with fixing units 2 on its periphery, an additional empty space will be formed in the center of the mounting plate 11. By reasonably arranging and adjusting the size of the fixing units 2, an additional fixing unit 2 can be set on the top of the mounting plate 11, which can increase the number of products that can be processed during the sandblasting process and improve the sandblasting efficiency.

[0063] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
