DETAILED DESCRIPTION

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0023] like Figures 1 to 4 As shown, the sheet metal housing elastic positioning structure includes a bracket 1, a support 3 on the top of the bracket 1, and a cylinder 2 on one side of the bracket 1. The cylinder 2 includes a piston rod 6, which is connected to a baffle 4. The baffle 4 is located on the side of the support 3 and has a stop block 5. The cylinder 2 drives the baffle 4 to rise and fall, satisfying the positioning of housings of various heights and sizes. The baffle 4 is used to contact the outside of the housing to achieve positioning. The push rod 10 utilizes the compressibility of the spring 8 to achieve axial movement of a certain length. When the housing contacts the stop block 5, elastic contact is formed, thereby correcting the positioning error of the housing. This allows the baffle 4 to fully contact the housing for reliable positioning, ensuring the accuracy requirements of the housing in subsequent stamping, welding, and other processes.

[0024] like Figures 1 to 3 As shown, a mounting plate 7 is provided on the outer side of the baffle 4, and a fixing bolt 11 is used to connect the mounting plate 7 to the baffle 4. A push rod 10 passes through the mounting plate 7, and a spring 8 is sleeved on the push rod 10. A stop block 5 is fixedly connected to one end of the push rod 10, and a limiting plate 9 is provided at the other end of the push rod 10. The two ends of the spring 8 contact the mounting plate 7 and the baffle 4 respectively, and the end face of the stop block 5 protrudes from the baffle 4. The fixing bolt 11 is used to fix the mounting plate 7 to the baffle 4. Multiple fixing bolts 11 are provided to ensure its installation accuracy. The baffle 4 is fixedly connected to the push rod 10, and the limiting plate 9 is used to prevent the push rod 10 from coming off the mounting plate 7. After the housing contacts the stop block 5, the two ends of the spring 8 are compressed by the pressure of the mounting plate 7 and the baffle 4, and the stop block 5 moves axially at the same time. The two stop blocks 5 form a positioning of the two right-angled sides at the corner of the housing. The end face of the stop block 5 protrudes from the baffle 4 by a certain distance, so that the housing can first contact the stop block 5 when transported by the conveying mechanism, and then the spring 8 is compressed to make the stop block 5 move and contact the baffle 4 again; the top of the baffle 4 is provided with an opening 18, so that the stop block 5 can pass through the baffle 4. The stop block 5 is located in the opening 18, which is U-shaped and adapted to the circular stop block 5.

[0025] like Figures 1 to 3 As shown, there are two baffles 4, and a connecting frame 20 connects the two baffles 4. The piston rod 6 is connected to the connecting frame 20, which has an L-shaped structure. The two baffles 4 and the stop block 5 are located on the outer side of the corner of the support 3, forming a right-angle support and positioning for the two surfaces of the corner of the housing. The connecting frame 20 connects and fixes the two baffles 4. Its L-shaped design is used to achieve angle turning, so that a single cylinder 2 can simultaneously drive the lifting and lowering of the two baffles 4.

[0026] like Figures 1 to 3As shown, the cylinder 2 is a double stroke cylinder 2. The piston of the double stroke cylinder 2 has two strokes, and an initial position, thereby meeting the positioning requirements of various height shells.

[0027] As shown in the drawings, the limiting plate 9 is provided with a connecting bolt 19 in the middle, the connecting bolt 19 passes through the limiting plate 9 and connects the push rod 10. Through the bolt, the installation and disassembly of the push rod 10 are facilitated, and the bolt connecting the push rod 10 prevents the rotation of the push rod 10, ensuring the reliable positioning accuracy. Figure 4

[0028] As shown in the drawings, the end of the baffle 4 is provided with an inclined angle 13, and the edge of the support 3 is provided with an inclined surface structure. The above structure can guide the incoming shell along the inclined angle 13 of the baffle 4 and the inclined surface of the support 3 to the support 3, reducing the contact damage of the shell. Figure 1

[0029] As shown in the drawings, the side of the bracket 1 is provided with a guide rail 14, the inner side of the baffle 4 is provided with a sliding block 15, and the sliding block 15 cooperates with the guide rail 14. The above structure is used to ensure that the moving direction of the baffle 4 driven by the cylinder 2 is accurate, and the position accuracy of the baffle 4 at different heights is reliable, thereby ensuring the reliable positioning accuracy. Figure 1

[0030] As shown in the drawings, the support 3 and the bracket 1 are connected with mounting bolts 12. The support 3 is a supporting part of the shell, and the plurality of mounting bolts 12 facilitates the disassembly of the support 3, which is conducive to the universal use of other parts. According to the size of the shell produced in different equipment, different sizes of the support 3 can be replaced to meet the production requirements. Figure 1

[0031] As shown in the drawings, the cylinder 2 and the bracket 1 are provided with fixing plates 16 at the bottom, and the fixing plates 16 are provided with fixing holes 17. The fixing plates 16 and the fixing holes 17 are used to install the cylinder 2 and the bracket 1 on the equipment, the fixing plates 16 enlarge the contact area of the two with the equipment table, ensuring the installation accuracy, and the plurality of fixing holes 17 further ensure the fixing effect. Figure 1

[0032] The positioning process of the shell is as follows: according to the height of the incoming shell part, the piston stroke of the cylinder 2 is controlled to adapt to the shell, when the shell contacts the stop block 5, the spring 8 is compressed by a certain distance under pressure, in this process, one end of the shell is elastically contacted by two stop blocks 5 to adjust the positioning error, until the baffle 4 contacts the shell, the elastic positioning structure is used in pairs, and the positioning error of the four ends or two ends of the shell is corrected at the same time, so that the shell is accurately positioned.

[0033] ​​​​​The sheet metal shell elastic positioning structure realizes the positioning of the shell through the setting of the baffle 4, and then realizes the correction of the positioning error of the shell by the elastic contact of the stop block 5 to the shell, so as to meet the positioning precision requirement in the production of the shell; the cylinder 2 is further set to meet the height adjustment of the baffle 4 and the stop block 5, so as to realize the positioning of the shell with different height sizes, the application range is wide, the frequent replacement process of the traditional baffle 4 is saved, and the production efficiency is improved; the sheet metal shell elastic positioning structure is convenient to assemble and disassemble, is reasonable in design, and is high in universality.
