Description

Technical Field

[0001] This utility model relates to a shielding and protective tool, and more particularly to a bolt protection device for vehicle axle spraying. Background Technology

[0002] In manufacturing processes, products often require painting. For example, in the production of front / rear drive axle assemblies for engineering bridges, painting is necessary. Before painting, bolts need to be masked and protected. Currently, bolt masking and protection typically involves individually placing plastic sleeves over each bolt, but these sleeves are prone to loosening during painting. Alternatively, masking tape can be wrapped around the bolts, but this method is time-consuming, and the masking tape cannot be reused, resulting in high costs. Therefore, there is an urgent need for a tooling that can conveniently mask and protect bolts during painting. Utility Model Content

[0003] The purpose of this utility model is to provide a bolt protection device for axle painting, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A bolt protection device for axle painting includes: a base plate; a protective sleeve, one end of which is connected to the base plate, the end of which is closed and the end away from the base plate is open, and there are multiple protective sleeves; a reinforcing plate, which has connecting holes respectively opposite to the multiple protective sleeves, the multiple protective sleeves passing through the multiple connecting holes, and the reinforcing plate and the multiple protective sleeves are fixed relative to each other.

[0006] This technical solution has at least the following beneficial effects: multiple protective sleeves are connected to the base plate, and the protective sleeves are positioned and reinforced by a reinforcing plate. One end of the protective sleeve connected to the base plate is a closed design, which can seal the inside of the protective sleeve for protection, while the other end of the protective sleeve is an open design. In use, the open ends of the multiple protective sleeves are respectively fitted onto the bolts that need to be covered and protected, which can quickly cover and protect multiple bolts. After use, the entire set can be quickly removed from the bolts. This effectively reduces the labor intensity of bolt covering and protection, improves the bolt covering and protection effect, and improves the overall work efficiency. In addition, the entire protective fixture can be reused, which helps to reduce the overall production cost.

[0007] As a further improvement to the above technical solution, one end of the protective sleeve is welded to the base plate, and the outer side of the protective sleeve is welded to the reinforcing plate. The protective sleeve is fixed to the base plate by welding, and then the reinforcing plate is welded to the outer side of the protective sleeve. In this way, the protective sleeve, the base plate, and the reinforcing plate can be connected to form a whole, improving the overall structural stability.

[0008] As a further improvement to the above technical solution, a positioning groove is provided on the base plate opposite the position of the protective sleeve, and one end of the protective sleeve is embedded in the positioning groove. When connecting the protective sleeve to the base plate, one end of the protective sleeve is embedded in the positioning groove, which provides pre-positioning for the protective sleeve, improving the accuracy of the protective sleeve's position on the base plate. Then, the protective sleeve is welded to the base plate. This improves the accuracy of the protective sleeve's position on the base plate, thereby improving the smoothness of simultaneously covering multiple bolts with multiple protective sleeves for shielding and protection.

[0009] As a further improvement to the above technical solution, an annular step is provided on the outer side of the ends of the multiple protective sleeves away from the base plate, and the reinforcing plate abuts against the annular step. When the reinforcing plate is fixed to the outside of the protective sleeve, since the annular step is provided on the outside of the protective sleeve, the connecting hole on the reinforcing plate is aligned with the protective sleeve, so that the reinforcing plate is fitted onto the outside of the protective sleeve. By using the abutment between the reinforcing plate and the annular step, the reinforcing plate can be quickly and accurately positioned, improving the accuracy of the reinforcing plate's fixed position on the outside of the protective sleeve. Welding the protective sleeve and the reinforcing plate at this time can further improve the quality of their mutual fixation.

[0010] As a further improvement to the above technical solution, the protective sleeve includes a main body segment and a connecting segment connected to each other. The outer diameter of the main body segment is larger than the outer diameter of the connecting segment. The reinforcing plate abuts against the end of the main body segment near the connecting segment, and the connecting segment is connected to the base plate. Because the outer diameter of the main body segment is larger than that of the connecting segment, a stepped structure is formed on the outer side of the end of the protective sleeve near the base plate. When installing the protective sleeve, the connecting segment is passed through the connecting hole on the reinforcing plate and connected to the base plate. At this time, the reinforcing plate abuts against the end of the main body segment, allowing for quick and accurate positioning of the reinforcing plate. This effectively improves the accuracy of the reinforcing plate's fixed position on the outside of the protective sleeve and increases the efficiency of the relative connection and fixation between the reinforcing plate and the protective sleeve.

[0011] As a further improvement to the above technical solution, a connecting cap is inserted into the side of the base plate away from the reinforcing plate. The head of the connecting cap abuts against the side of the base plate away from the reinforcing plate. The connecting section is threaded into the connecting cap, and one end of the connecting cap abuts against the reinforcing plate. A spring is sleeved on the outside of the connecting section, and the spring presses the reinforcing plate against the head of the connecting cap. When fixing the protective sleeve to the base plate, the connecting cap is inserted from the side of the base plate away from the reinforcing plate. The connecting cap abuts against the reinforcing plate, pressing and fixing the reinforcing plate to the end of the main body section, thereby fixing the reinforcing plate relatively to the outside of the protective sleeve. The connecting section is fixed to the base plate by the threaded connection between the connecting section and the connecting cap. At this time, the spring located between the base plate and the reinforcing plate is elastically compressed. The spring presses the base plate against the head of the connecting cap, which can press and position the reinforcing plate and provide pre-tightening force for the connection between the connecting cap and the protective sleeve. In this way, the whole assembly and disassembly are convenient, and individual protective sleeves can be flexibly replaced and maintained according to usage needs, effectively reducing the cost of use and maintenance.

[0012] As a further improvement to the above technical solution, the multiple connecting holes are oblong in shape, and oblong holes are respectively provided on the base plate opposite to the multiple connecting holes. Multiple connecting caps pass through the multiple oblong holes. To meet different usage needs, the position of the protective sleeve can be finely adjusted. Specifically, first, the head of the connecting cap is loosened away from the base plate. At this time, the connecting cap can be adjusted along the oblong hole. Correspondingly, the connecting section can also be adjusted along the oblong connecting hole, thereby changing the position of the protective sleeve. After adjustment, the head of the connecting cap is locked and fixed to the base plate to lock the position of the protective sleeve. In this way, the installation position of the protective sleeve can be changed according to different usage needs, further improving the overall flexibility and versatility of use.

[0013] As a further improvement to the above technical solution, the head of the connecting cap is a regular polygon. When it is necessary to rotate the head of the connecting cap, an external tool is used to rotate the head of the connecting cap. Since the head of the connecting cap is a regular polygon, it is convenient to apply force to rotate the head of the connecting cap, thus improving the user experience.

[0014] As a further improvement to the above technical solution, both the base plate and the reinforcing plate are annular, and the protective sleeve is provided with multiple sleeves spaced apart around the center of the base plate. The annular base plate and reinforcing plate can better adapt to the shape of the front / rear drive axle assembly of the engineering bridge, and the annular opening formed in the middle of the base plate and reinforcing plate can facilitate the entry of external equipment and machinery. Thus, the overall design is more reasonable and facilitates operations such as painting.

[0015] As a further improvement to the above technical solution, an elastic sleeve is provided inside the protective sleeve. When the protective sleeve is used to protect the bolt, the elastic sleeve is placed on the outside of the bolt, allowing the elastic sleeve to fit more tightly against the outside of the bolt, reducing wear on the bolt, and improving the protective effect on the bolt.

[0025] Reference Figure 1 A bolt protection device for axle painting includes a base plate 100, a protective sleeve 200, and a reinforcing plate 300. One end of the protective sleeve 200 is connected to the base plate 100, and the end of the protective sleeve 200 connected to the base plate 100 is closed, while the end of the protective sleeve 200 away from the base plate 100 is open. There are multiple protective sleeves 200, which are arranged according to the location of the bolts in actual use. The reinforcing plate 300 has connecting holes at the positions of the multiple protective sleeves 200, and the multiple protective sleeves 200 pass through the multiple connecting holes. The reinforcing plate 300 and the multiple protective sleeves 200 are fixed relative to each other.

[0026] As described above, multiple protective sleeves 200 are connected to the base plate 100, and the reinforcing plate 300 is used to position and reinforce the protective sleeves 200. One end of the protective sleeve 200 connected to the base plate 100 is a closed design, which can seal and protect the inside of the protective sleeve 200. The other end of the protective sleeve 200 is an open design. When in use, the open ends of the multiple protective sleeves 200 are respectively fitted onto the bolts that need to be covered and protected, which can quickly cover and protect multiple bolts. After use, the whole thing can be quickly removed from the bolts. This effectively reduces the labor intensity of bolt covering and protection, improves the bolt covering and protection effect, and improves the overall work efficiency. In addition, the entire protective fixture can be reused, which helps to reduce the overall production cost.

[0027] Multiple protective sleeves 200 are fixed relative to the base plate 100 and the reinforcing plate 300. There are various structural forms; in Embodiment 1, one end of each protective sleeve 200 is welded to the base plate 100, and the outer side of each protective sleeve 200 is welded to the reinforcing plate 300. The protective sleeves 200 are fixed to the base plate 100 by welding, and the reinforcing plate 300 is then welded to the outer side of the protective sleeves 200. This connects the protective sleeves 200, the base plate 100, and the reinforcing plate 300 into a single unit, improving the overall structural stability.

[0028] When the protective sleeve 200 is fixed to the base plate 100, it can be directly assembled by machine. By feeding multiple protective sleeves 200 one by one onto the base plate 100, the feeding accuracy of the protective sleeve 200 can be improved. If the protective sleeve 200 needs to be fixed to the base plate 100 manually, the protective sleeve 200 needs to be positioned manually. In order to improve the feeding accuracy of the protective sleeve 200, in this embodiment, the base plate 100 is provided with a positioning groove at the position opposite to the protective sleeve 200, and one end of the protective sleeve 200 is embedded in the positioning groove. When connecting the protective sleeve 200 to the base plate 100, one end of the protective sleeve 200 is embedded in the positioning groove. The positioning groove provides pre-positioning for the protective sleeve 200, improving the positional accuracy of the protective sleeve 200 fixed on the base plate 100. Then, the protective sleeve 200 is welded and fixed to the base plate 100. This improves the positional accuracy of the protective sleeve 200 installed on the base plate 100, thereby improving the smoothness of multiple protective sleeves 200 being simultaneously fitted onto the outside of multiple bolts for shielding and protection.

[0029] To improve the positioning accuracy of the connection between the reinforcing plate 300 and the protective sleeve 200, in this embodiment, an annular step is provided on the outer side of the ends of the multiple protective sleeves 200 away from the base plate 100. That is, the outer diameter of the end of the protective sleeve 200 away from the base plate 100 is larger than the outer diameter of the end of the protective sleeve 200 near the base plate 100. At this time, an annular step is formed at the junction of the two, and the reinforcing plate 300 abuts against the annular step. When the reinforcing plate 300 is fixed to the outside of the protective sleeve 200, since the annular step is provided on the outside of the protective sleeve 200, the connecting hole on the reinforcing plate 300 is aligned with the protective sleeve 200, so that the reinforcing plate 300 is fitted onto the outside of the protective sleeve 200. By using the abutment between the reinforcing plate 300 and the annular step, the reinforcing plate 300 can be quickly and accurately positioned, improving the accuracy of the fixed position of the reinforcing plate 300 on the outside of the protective sleeve 200. Then, welding the protective sleeve 200 and the reinforcing plate 300 can further improve the quality of their mutual fixation.

[0030] like Figure 2 and Figure 3As shown in the second embodiment, which connects multiple protective sleeves 200 to the base plate 100 and the reinforcing plate 300, the protective sleeve 200 includes a main body section 210 and a connecting section 220 that are connected to each other. The outer diameter of the main body section 210 is larger than the outer diameter of the connecting section 220. The reinforcing plate 300 abuts against the end of the main body section 210 near the connecting section 220. The connecting section 220 is connected to the base plate 100. Since the outer diameter of the main body section 210 is larger than the outer diameter of the connecting section 220, a stepped structure is formed at the outer end of the protective sleeve 200 near the base plate 100. When installing the protective sleeve 200, the connecting section 220 is passed through the connecting hole on the reinforcing plate 300 and connected to the base plate 100. At this time, the reinforcing plate 300 is placed against the end of the main body section 210, which can quickly and accurately position the reinforcing plate 300, effectively improving the positional accuracy of the reinforcing plate 300 on the outside of the protective sleeve 200, and improving the efficiency of the relative connection and fixation between the reinforcing plate 300 and the protective sleeve 200.

[0031] In Embodiment 2, the reinforcing plate 300 can also be fixed to the protective sleeve 200 by welding. In order to facilitate the disassembly and assembly of the protective sleeve 200, in this embodiment, a connecting cap 410 is inserted on the side of the base plate 100 away from the reinforcing plate 300. The head of the connecting cap 410 abuts against the side of the base plate 100 away from the reinforcing plate 300. The connecting segment 220 is threaded into the connecting cap 410. One end of the connecting cap 410 abuts against the reinforcing plate 300. A spring 420 is sleeved on the outside of the connecting segment 220. The spring 420 presses the reinforcing plate 300 against the head of the connecting cap 410. When the protective sleeve 200 is fixed to the base plate 100, the connecting cap 410 is inserted from the side of the base plate 100 away from the reinforcing plate 300. The connecting cap 410 abuts against the reinforcing plate 300, pressing and fixing the reinforcing plate 300 to the end of the main body section 210. This fixes the reinforcing plate 300 to the outside of the protective sleeve 200. The connecting section 220 is fixed to the base plate 100 by the threaded connection between the connecting section 220 and the connecting cap 410. At this time, the spring 420 located between the base plate 100 and the reinforcing plate 300 is elastically compressed. The spring 420 presses the base plate 100 against the head of the connecting cap 410, which can press and position the reinforcing plate 300 and provide pre-tightening force for the connection between the connecting cap 410 and the protective sleeve 200. In this way, the whole assembly and disassembly are convenient, and the individual protective sleeves 200 can be flexibly replaced and maintained according to the needs of use, effectively reducing the cost of use and maintenance.

[0032] Since there are multiple bolts that need to be shielded and protected, and multiple protective sleeves 200 need to shield and protect the bolts, it is necessary to ensure that multiple protective sleeves 200 can be fitted onto multiple bolts at the same time. In order to reduce the problem of not being able to fit multiple protective sleeves 200 onto multiple bolt heads at the same time due to installation errors during the installation of multiple protective sleeves 200, in this embodiment, the multiple connecting holes are shaped like waists. The base plate 100 is provided with waist-shaped holes at the positions opposite to the multiple connecting holes, and the multiple connecting caps 410 pass through the multiple waist-shaped holes respectively. To meet different usage needs, the position of the protective sleeve 200 can be finely adjusted. Specifically, first loosen the head of the connecting cap 410 away from the base plate 100. At this time, the connecting cap 410 can be adjusted along the waist-shaped hole. Correspondingly, the connecting section 220 can also be adjusted along the waist-shaped connecting hole, thereby changing the position of the protective sleeve 200. After the adjustment is completed, lock the head of the connecting cap 410 onto the base plate 100 to lock the position of the protective sleeve 200. In this way, the installation position of the protective sleeve 200 can be changed according to different usage needs, further improving the overall flexibility and versatility of use.

[0033] The head of the connecting cap 410 has a larger outer diameter than the portion that penetrates the base plate 100. While the head of the connecting cap 410 could be circular, in this embodiment, it is a regular polygon. When the head of the connecting cap 410 needs to be rotated, an external tool is used to rotate it. Because the head of the connecting cap 410 is a regular polygon, it is easy to apply force to rotate it, improving the user experience.

[0034] In some embodiments, both the base plate 100 and the reinforcing plate 300 are annular, and the protective sleeve 200 is provided in multiple spaced intervals around the center of the base plate 100. The annular base plate 100 and reinforcing plate 300 can better adapt to the shape of the front / rear drive axle assembly of the engineering bridge, and the annular opening formed in the middle of the base plate 100 and the reinforcing plate 300 can facilitate the entry of external equipment and machinery. Thus, the overall design is more reasonable and facilitates operations such as painting.

[0035] The internal space of the protective sleeve 200 can be larger than the bolt that needs to be protected. When the sleeve is fitted over the bolt, there is a certain gap between the protective sleeve 200 and the bolt. To ensure a tighter fit, in this embodiment, an elastic sleeve is provided inside the protective sleeve 200. The elastic sleeve can be made of rubber, sponge, or similar materials. When the protective sleeve 200 is used to protect the bolt, the elastic sleeve fits more tightly against the bolt, reducing wear and improving the protective effect.

[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
