Description

Technical Field

[0001] This utility model relates to the field of gear shot blasting auxiliary technology, and more specifically, to a gear shot blasting tooling and a gear shot blasting positioning mechanism. Background Technology Gear shot blasting is a process that cleans or strengthens the surface of gears by high-speed projectile shot. It is primarily used to improve the fatigue strength, surface quality, and adhesion of subsequent coatings. A high-speed rotating impeller propels shot (such as steel shot or ceramic powder) onto the gear surface, causing plastic deformation through impact and introducing residual compressive stress, thus improving fatigue resistance. Currently, during gear shot blasting, the gear is placed directly onto the shot blasting machine trolley, with the larger end face of the gear directly contacting the trolley surface. After the first shot blasting, the oxide scale at the contact area between the gear and the trolley is not removed, requiring a second shot blasting to remove the oxide scale. In other words, the existing gear shot blasting process is: loading → first shot blasting → flipping → second shot blasting → unloading.

[0002] The inventors discovered during their research that existing gear shot blasting techniques have at least the following drawbacks: If the oxide scale is not completely removed by the first shot blasting, it needs to be turned over and shot blasted again, which is inefficient. Before the second shot blasting, the gears need to be turned over manually, which is labor-intensive and can easily cause fatigue for the employees. Utility Model Content

[0003] The purpose of this utility model includes, for example, providing a gear shot blasting fixture and a gear shot blasting positioning mechanism, which can remove oxide scale in one shot blasting without the need for secondary shot blasting, thereby reducing labor intensity and improving shot blasting efficiency.

[0004] The embodiments of this utility model can be implemented as follows: Firstly, this utility model provides a gear shot blasting fixture, comprising: The assembly includes a connector and multiple support plates, all of which are fixedly connected to the connector. The multiple support plates are arranged in a ring and form a hollow area. Each support plate has a first support portion and a second support portion. The connector is spaced apart from the first support portion. The first support portions of the multiple support plates are used to support the connector on the shot blasting machine table and suspend the connector. The second support portions of the multiple support plates are used to position the gear to be processed.

[0005] In an optional embodiment, the second support portion is provided with support teeth for contacting the end face of the gear to be processed.

[0006] In an optional embodiment, the number of support teeth is multiple, and the multiple support teeth are arranged at intervals along a set direction.

[0007] In an optional embodiment, the second support is configured as an inclined surface, and when the first support is located below the second support, the height of the inclined surface gradually increases in the direction from the middle of the hollow region to the outside of the hollow region.

[0008] In an optional embodiment, the connector is configured as a connecting ring, and the plurality of support plates are arranged at intervals in the circumferential direction of the connecting ring.

[0009] In an optional embodiment, the connecting ring is located within the hollow area enclosed by the plurality of support plates.

[0010] In an optional embodiment, the connector is welded and fixed to the support plate.

[0011] Secondly, this utility model provides a gear shot blasting positioning mechanism, the gear shot blasting positioning mechanism comprising: The gear shot blasting fixture described in any one of the foregoing embodiments is connected together.

[0012] In an optional embodiment, the gear shot blasting positioning mechanism further includes a fixing member, and the plurality of gear shot blasting fixtures are arranged in a ring, with adjacent gear shot blasting fixtures connected by the corresponding fixing member in the arrangement direction.

[0013] In an optional embodiment, the fastener is welded to the connector and / or the support plate.

[0014] The beneficial effects of this utility model embodiment include, for example: In summary, the gear shot blasting fixture provided in this embodiment utilizes a first support portion of multiple support plates supported on the shot blasting machine table, with a second support portion positioned above the first support portion. The gear to be processed can then be hoisted onto the multiple support plates using a lifting tool, and positioned by the second support portions of the multiple support plates. Due to the gap between the connecting parts and the table table, shot can enter the lower area of ​​the gear to be processed from below the connecting parts, allowing the shot to perform shot blasting on the bottom end face of the gear. Because the multiple second support plates are arranged in a ring, with gaps between adjacent support plates, the contact area between the support plates and the bottom end face of the gear to be processed is small, resulting in minimal obstruction. A single shot blasting operation is sufficient, eliminating the need for a second shot blasting, saving the gear flipping operation, simplifying the process, reducing labor intensity, and improving shot blasting efficiency.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0023] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0024] In existing technology, when shot blasting gears, the gears are first placed upright on the shot blasting machine table 001, with the large end face of the gear in contact with the table and blocked by it. After one shot blasting, the gears need to be flipped over and laid down to expose the large end face for a second shot blasting. This process is cumbersome, inconvenient, labor-intensive, and inefficient.

[0025] In view of this, the designer provides a gear shot blasting fixture that can reduce the area of ​​the gear that is obscured during shot blasting, and can meet the requirements in one shot blasting, simplifying the process, reducing labor intensity and increasing efficiency.

[0026] Please refer to Figures 1-3 This embodiment provides a gear shot blasting fixture, which includes a connector 100 and multiple support plates 200. The multiple support plates 200 are all fixedly connected to the connector 100, and are arranged in a ring to form a hollow area. Each support plate 200 has a first support portion 210 and a second support portion 220, and the connector 100 is spaced apart from the first support portion 210. The first support portions 210 of the multiple support plates 200 are used to support the connector 100 on the shot blasting machine table 001, suspending the connector 100. The second support portions 220 of the multiple support plates 200 are used to position the gear 003 to be processed.

[0027] As described above, the working principle of the gear shot blasting fixture provided in this embodiment is as follows: Please refer to Figure 3In use, multiple gear shot blasting fixtures can be used together; this embodiment does not limit the number. An example using a single gear shot blasting fixture is provided. The first support portion 210 of the multiple support plates 200 of the gear shot blasting fixture is supported on the shot blasting machine table 001, with the second support portion 220 positioned above the first support portion 210. Then, a lifting tool can be used to lift the gear 003 to be processed onto the multiple support plates 200, and it is positioned by the second support portion 220 of the multiple support plates 200. Due to the gap between the connecting member 100 and the table, the shot can enter the lower area of ​​the gear 003 to be processed from below the connecting member 100, allowing the shot to perform shot blasting on the bottom end face of the gear 003. Since the multiple second support plates 200 are arranged in a ring and there is a gap between adjacent support plates 200, the contact area between the support plate 200 and the bottom end face of the gear 003 to be processed is small and the obstruction area is small. One shot blasting can meet the requirements without the need for secondary shot blasting, eliminating the gear flipping operation, simplifying the process, reducing labor intensity, and improving shot blasting efficiency.

[0028] The following embodiments illustrate the details of the gear shot blasting fixture of this application by way of example.

[0029] Please refer to Figures 1-3 In this embodiment, optionally, the gear shot blasting fixture includes a connector 100 and multiple support plates 200. The multiple support plates 200 are fixedly connected by the connector 100.

[0030] Please refer to Figure 1 In this embodiment, optionally, the connector 100 can be configured as a connecting ring. For example, the connector 100 can be configured as a circular ring or a polygonal ring, etc. In this embodiment, a circular ring is used as an example for illustration. It should be understood that the shape and size of the connecting ring can be designed as needed, and no specific limitation is made in this embodiment.

[0031] Please refer to Figure 2In this embodiment, optionally, the support plate 200 can be configured as a right-angled trapezoidal plate. The support plate 200 includes a bottom surface 201, an inner surface 202, a top surface 203, and an outer surface 204 connected in sequence. The bottom surface 201 and the top surface 203 are opposite to each other, and the inner surface 202 and the outer surface 204 are opposite to each other. The bottom surface 201 is perpendicular to both the inner surface 202 and the outer surface 204. The top surface 203 is inclined relative to the bottom surface 201, and the distance between the top surface 203 and the bottom surface 201 gradually increases in the direction from the inner surface 202 to the outer surface 204. In other words, when the bottom surface 201 is supported on the table, the top surface 203 is located above the bottom surface 201, and the height of the side of the top surface 203 near the inner surface 202 is lower than the height of the side of the top surface 203 near the outer surface 204. The first support part 210 is disposed on the bottom surface 201, or the bottom surface 201 is the first support part 210. The second support 220 is disposed on the top surface 203, or the top surface 203 is the second support 220. Since the top surface 203 is inclined, that is, the top surface 203 is a slope, when the multiple support plates 200 are arranged in a ring, the area enclosed by the multiple top surfaces 203 is roughly a conical area, and the size gradually increases from the bottom surface 201 to the top surface 203. It can accommodate the positioning of various gears with different diameters, making it flexible and widely applicable.

[0032] Furthermore, support teeth 230 can be provided on the top surface 203. The number of support teeth 230 can be one or more. When there are multiple support teeth 230, the multiple support teeth 230 are evenly spaced along a set direction, which is the length direction of the top surface 203. By providing multiple support teeth 230, the contact area between the second support part 220 and the bottom end face of the gear 003 to be processed can be further reduced, thereby improving the shot blasting effect.

[0033] It should be noted that the number of support plates 200 is designed as needed. In this embodiment, the number of support plates 200 can be three.

[0034] Furthermore, three support plates 200 can be disposed on the outer circumferential surface of the connecting ring. The three support plates 200 are evenly spaced on the outer circumferential surface of the connecting ring, and each support plate 200 is welded and fixed to the connecting ring. That is, the connecting ring is located in the hollow area enclosed by the three support plates 200.

[0035] Obviously, in some embodiments, the three support plates 200 can also be fixed on the inner side of the connecting ring.

[0036] It is worth noting that in some embodiments, the connector 100 can be configured as a rod, and there can be multiple connectors 100. Two adjacent support plates 200 are fixedly connected by at least one connector 100. Regardless of whether the connector 100 is configured as a ring or a rod, when the support plates 200 are connected by the connector 100, the lower side of the connector 100, that is, the side closer to the table surface, has a distance L from the first support portion 210. The lower side of the connector 100 is higher than the first support portion 210. In this way, when the first support portion 210 contacts the table surface, the connector 100 is in a suspended state, and the distance L between the connector 100 and the table surface allows the shot to enter the bottom end face of the gear 003 to be processed from below the connector 100.

[0037] In addition, the thickness of the support plate 200 can be designed as needed. While meeting the support strength requirements, the thickness of the support plate 200 can be reduced, which can further reduce the contact area with the bottom end face of the gear 003 to be processed.

[0038] The gear shot blasting fixture provided in this embodiment supports the gear 003 to be processed through the support plate 200. The bottom end face of the gear is obscured by a small area, and the requirements can be met in one shot blasting. The process is simple, the labor intensity is low, and the efficiency is high.

[0039] Please refer to Figure 4 This embodiment also provides a gear shot blasting positioning mechanism, which includes multiple gear shot blasting fixtures as described above. The multiple gear shot blasting fixtures are connected to form a unit, resulting in higher stability.

[0040] It should be understood that the number of gear shot blasting fixtures in each unit is designed as needed and determined according to the number of gears 003 to be processed that the hoisting tool can hoist at one time. For example, when the hoisting tool can hoist four gears at one time, four gear shot blasting fixtures can be connected to form a unit, and the arrangement of the four gear shot blasting fixtures is consistent with the arrangement of the four gears to be hoisted.

[0041] Optionally, the gear shot blasting positioning mechanism may also include a fixing element 002. The number of fixing elements 002 can be one or more, depending on the needs. The fixing element 002 can be set as a rod, and adjacent gear shot blasting fixtures can be welded and fixed together by at least one fixing element 002.

[0042] For example, in this embodiment, four gear shot blasting fixtures are used as an example. There are six fixing members 002. The four gear shot blasting fixtures are arranged in a ring. In the ring arrangement direction, the connecting parts 100 of adjacent gear shot blasting fixtures are fixedly connected by one fixing member 002. In the diagonal direction, the support plates 200 corresponding to two adjacent gear shot blasting fixtures are fixedly connected by one fixing member 002. The four gear shot blasting fixtures are arranged side by side, resulting in a stable and reliable structure.

[0043] The gear shot blasting positioning mechanism provided in this embodiment can simultaneously position multiple gears 003 to be processed, improving positioning efficiency. Each gear only needs to be shot blasted once, resulting in high efficiency and low cost.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
