[0001] This utility model belongs to the field of assembly fixture technology, specifically relating to a nameplate assembly pressure holding fixture. Background Technology
[0002] Currently, cylindrical pins are commonly used to position the nameplate in the assembly process of the outer shell and the nameplate. Specifically, during assembly, the outer shell is located below, and the nameplate is located above. Positioning is achieved by the cylindrical pin passing through the corresponding holes in the upper shell and the nameplate. In actual assembly, because the mounting hole size of the nameplate is usually larger than the corresponding hole in the upper shell, relative displacement can easily occur between the nameplate and the upper shell due to the gap between the holes, resulting in low positioning accuracy of the nameplate. This insufficient positioning accuracy will affect subsequent welding, bonding, and other processes, and may also lead to insufficient connection strength due to inaccurate positioning, reducing the structural stability and service life of the product. Utility Model Content

The external support member is used to position the nameplate. A pressure-holding assembly is installed above the fixed base. The pressure-holding assembly includes a pressure-holding cylinder. The driving end of the pressure-holding cylinder acts on the outside of the nameplate to cooperate with the fixed base to assemble and press the nameplate and the outer shell together.
[0005] In some implementations, the external support assembly includes two pneumatic finger cylinders, which are spaced apart and used to position the two ends of the nameplate.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0021] Example 1: Please see Figure 1 and Figure 2 The present invention discloses a nameplate assembly pressure-holding fixture, comprising a fixed base 1 with an assembly groove 11 for placing a shell 5 and a nameplate 4; an outer support assembly 2 installed below the fixed base 1, the outer support assembly 2 including a pneumatic finger cylinder 21 and a detachable outer support member 22, one end of the outer support member 22 being installed at the drive end of the pneumatic finger cylinder 21, the bottom of the assembly groove 11 having a positioning hole 12, the other end of the outer support member 22 extending into the assembly groove 11 through the positioning hole 12, the outer support member 22 being used to position the nameplate 4; and a pressure-holding assembly 3 installed above the fixed base 1, the pressure-holding assembly 3 including a pressure-holding cylinder 32, the drive end of the pressure-holding cylinder 32 acting on the outside of the nameplate 4, for cooperating with the fixed base 1 to assemble and press the nameplate 4 and the shell 5 together.
[0022] Specifically, all components of the nameplate assembly pressure-holding fixture are built on the chassis 6. The chassis 6 includes a cover 61 and a body 62. The cover 61 is connected to the body 62 by a hinge and locked in place by a buckle 63. The fixing base 1 is arranged in an arc shape on the cover 61 at the top of the chassis 6. The fixing base 1 is provided with an assembly slot 11 that fits the outer shell 5. The outer shell 5 is placed in the assembly slot 11 for initial positioning, and the nameplate 4 is placed on top of the outer shell 5. An external support assembly 2 is provided at the bottom of the fixing base 1. The external support assembly 2 includes a pneumatic finger cylinder 21 and an external support member 22. The pneumatic finger cylinder 21 is located at the bottom of the fixing base 1. The driving end of the pneumatic finger cylinder 21 is provided with the external support member 22. The external support member 22 extends into the positioning hole 12 on the assembly slot 11. The outer shell 5 and the nameplate 4 are both provided with through holes corresponding to the positioning hole 12. By driving the external support member 22 to perform an external support action in the through hole, the outer shell 5 and the nameplate 4 are further positioned and fixed. The pressure holding assembly 3 is positioned above the fixed base 1. The end of the pressure holding cylinder 32 matches and presses against the outer side of the nameplate 4, providing stable pressure to ensure that the nameplate 4 and the outer shell 5 fit tightly together.
[0023] Understandably, the housing 62 can be used to house important components such as gas guide pipes and circuit elements. The housing 62 is closed by the cover 61, providing concealment and protection to ensure the safe and stable operation of the nameplate assembly pressure-holding fixture. Furthermore, both the nameplate 4 and the outer shell 5 have positioning openings, allowing the outer support member 22 to be inserted into these openings. The outer support assembly 2 then drives the outer support member 22 to perform an outward support action, positioning the nameplate 4 and the outer shell 5. Then, in conjunction with the pressure-holding assembly 3, the pressure-holding cylinder 32 performs a downward pressing action to achieve the pressing process, thereby preventing the nameplate 4 from shifting during the pressing assembly process. In addition, compared with traditional cylindrical pin positioning, the positioning function of the external support component 2 can more accurately position the nameplate 4, reduce the relative positional deviation between the nameplate 4 and the outer shell 5 caused by inaccurate positioning, and reduce the probability of product appearance defects.
[0024] It is worth noting that the outer support 22 is a detachable structure, used to equip the outer support 22 with different shapes and structures on the drive end of the pneumatic finger cylinder 21 to adapt to the hole diameter on different nameplates 4. It can be determined according to the actual situation, so that the nameplate 4 and the outer shell 5 are horizontally limited by the outer support 22. This application does not limit it here.
[0025] In this embodiment, the nameplate 4 assembly pressure-holding fixture's fixing seat 1 uses an assembly slot 11 to initially position the outer shell 5, placing the nameplate 4 in the corresponding position on the outer shell 5. The outer support assembly 2 at the bottom of the fixing seat 1 further positions and fixes the nameplate 4 and the outer shell 5. The pneumatic finger cylinder 21 of the outer support assembly 2 drives the outer support member 22 to perform an outward support action, enabling the outer support member 22 to firmly position the outer shell 5 and the nameplate 4, preventing displacement during subsequent pressing. The pressure-holding cylinder 32 of the pressure-holding assembly 3 rises downward, its driving end acting on the nameplate 4 and cooperating with the fixing seat 1 to provide continuous and stable pressure to the nameplate 4 and the outer shell 5, thus achieving the assembly between the nameplate 4 and the outer shell 5.
[0026] Example 2: This embodiment is a further structural optimization of the nameplate assembly pressure-holding fixture of this utility model. Please refer to [link / reference]. Figure 1 and Figure 2 .
[0027] In some embodiments, the outer support assembly 2 includes two pneumatic finger cylinders 21, which are spaced apart and used to position the two ends of the nameplate 4.
[0028] Specifically, the external support assembly 2 can apply positioning force to both ends of the nameplate 4 through two spaced pneumatic finger cylinders 21, which can prevent the nameplate 4 from tilting or shifting due to unilateral force.
[0029] In some embodiments, the pneumatic finger cylinder 21 is a three-jaw pneumatic finger cylinder, which is used to drive the outer support member 22 to expand outward in a circular shape.
[0030] Specifically, the outer support assembly 2 uses a three-jaw pneumatic finger cylinder, which can drive three outward-facing base claws, each of which is equipped with an outer support component 22. When the three-jaw pneumatic finger cylinder is working, the three base claws will open outwards synchronously, thereby causing the outer support component 22 to expand outwards in a circular shape around the center position of the three base claws.
[0031] Understandably, this circular outward expansion motion allows the outer support 22 to achieve omnidirectional and uniform contact with the inner wall of the circular through hole on the nameplate 4. By applying positioning forces from multiple points around the circumference, stable positioning and fixing of the nameplate 4 can be provided, effectively limiting the translation and rotation of the nameplate 4 in the plane, and ensuring that the nameplate 4 is in a precise position during subsequent pressing and assembly.
[0032] In some embodiments, the outer side of the outer support member 22 is an arc surface, used to abut against the nameplate 4.
[0033] Specifically, the contact surface between the outer side of the outer support member 22 and the nameplate 4 is set as an arc surface to form a suitable curved surface contact in conjunction with the outer support action. When the outer support member 22 is pushed outward by the pneumatic finger cylinder 21, the arc surface will uniformly fit with the contact area of the nameplate 4. Through the positioning method of surface contact rather than point contact or line contact, the displacement of the nameplate 4 is restricted, while local stress concentration is reduced, and the warping of the nameplate 4 caused by the outer support is avoided.
[0034] In some embodiments, the pressure holding assembly 3 further includes a support plate 31, a pressure holding cylinder 32 is mounted on the top of the support plate 31, and the support plate 31 and the fixed base 1 are mounted on the same plane.
[0035] Specifically, the support plate 31 provides a stable mounting carrier for the pressure-holding cylinder 32, allowing the pressure-holding cylinder 32 to be adjusted to a fixed height and angle. Since the support plate 31 and the fixed base 1 are mounted on the same plane, it ensures relative stability between the pressure-holding cylinder 32 and the fixed base 1, forming a fixed whole. Understandably, when the pressure-holding cylinder 32 drives the pressing cover plate 323 to press down, the pressure can be precisely applied to the nameplate 4 in a preset direction, avoiding pressure direction deviation caused by external vibration or non-coplanarity. In this embodiment, the outer support component 2 of the nameplate assembly pressure-holding fixture uses two three-jaw pneumatic finger cylinders for external support positioning, which are used to apply positioning forces to both ends of the nameplate 4 respectively, improving the positioning stability. The outer support component 22 adopts a circular outward expansion movement mode, which can fully abut against the nameplate 4. Moreover, the contact surface of the outer support component 22 is an arc surface, which can effectively reduce local stress concentration and avoid warping during positioning due to differences between different batches. The pressure-holding cylinder 32 is fixed on the same plane as the fixed base 1 through the support plate 31, thereby ensuring that the pressure applied by the pressure-holding component 3 to the nameplate 4 can be accurately applied to the nameplate 4 in a preset direction.
[0036] Example 3: This embodiment is a further structural optimization of the nameplate assembly pressure-holding fixture of this utility model. Please refer to [link / reference]. Figure 2 and Figure 3 .
[0037] In some embodiments, the driving end of the pressure-holding cylinder 32 is provided with a pressing cover plate 323, and the pressing cover plate 323 is provided with a pressing block 324 on the side for abutting the nameplate 4. The pressing block 324 is used to adapt to the nameplate 4.
[0038] Specifically, the pressure-holding cylinder 32 uses the pressing cover plate 323 as an intermediate carrier between the driving end of the pressure-holding cylinder 32 and the nameplate 4. This allows the cylinder pressure to be evenly transmitted over a wider range, and also makes the pressing force in all directions more stable, avoiding uneven force on the nameplate 4 caused by single-point pressure. It is worth noting that a clamping block 324 is provided on the contact surface of the pressing cover plate 323. The clamping block 324 is designed to correspond to the shape of the nameplate 4. The clamping block 324 is provided with a limiting hole 325 and a fiber hole to prevent the external expansion component from damaging the nameplate 4 due to excessive external support. The clamping block 324 can be replaced according to the actual situation and the shape design of different nameplates 4.
[0039] In some embodiments, the pressure-holding cylinder 32 has a mounting groove 321 on its side, and a magnetic switch 322 is movably engaged in the mounting groove 321.
[0040] Specifically, magnetic switches 322 are installed at both the upper and lower ends of the pressure-holding cylinder 32. These magnetic switches 322 are used to detect the piston position of the pressure-holding cylinder 32. They determine the working state of the cylinder by sensing the signal from the magnetic ring on the piston, thus providing feedback on whether the piston has extended to its full position or retracted to its reset position. A mounting groove 321 is provided on the side of the pressure-holding cylinder 32, providing sliding adjustment space for the magnetic switch 322. Through a movable snap-fit connection, the magnetic switch 322 can be adjusted in position within the groove according to actual needs, precisely corresponding to different stroke nodes of the piston.
[0041] In some embodiments, the pressure-holding cylinder 32 is a biaxial cylinder.
[0042] Specifically, the pressure-holding cylinder 32 adopts a dual-axis cylinder, with two parallel guide rods moving synchronously with the cylinder piston rod. This provides axial driving force while the rigid support of the dual guide rods restricts the radial displacement of the piston rod, ensuring that the movement trajectory of the drive end remains linear during the pressing process. Understandably, the dual-axis structure, while outputting the same pressure, also enhances the torsional and eccentric load resistance of the drive end, making it suitable for assembling different types of nameplates 4.
[0043] In some embodiments, the pressure holding assembly 3 further includes a pressure regulating valve 7, which is connected to the air inlet of the pressure holding cylinder 32.
[0044] Specifically, a pressure regulating valve 7 is provided on the outside of the housing 62. The pressure regulating valve 7 is used to control the air intake pressure of the pressure holding cylinder 32. By adjusting the pressure of the compressed air entering the cylinder, the driving force output by the pressure holding cylinder 32 can be precisely controlled. The pressure can be flexibly adjusted according to actual needs to ensure that the output force of the pressure holding cylinder 32 meets the process requirements of the nameplate 4 pressing.
[0045] In some embodiments, the pressure holding assembly 3 further includes a time relay 8 for controlling the pressure holding cylinder 32.
[0046] Specifically, the pressure holding assembly 3 is equipped with a time relay 8, allowing the user to preset and adjust the pressure holding time. This time relay 8 controls the pressure holding duration of the pressure holding cylinder 32. By using preset time parameters, the duration of the pressure holding cylinder 32 in the pressing and holding state can be precisely controlled. It can be understood that when the pressure holding cylinder 32 drives the pressing cover plate 323 to press the nameplate 4 tightly, the time relay 8 starts timing. After the preset time is reached, a signal is sent to control the pressure holding cylinder 32 to perform a reset and retraction action. This achieves automated timing control of the pressure holding process for the nameplate 4 assembly, ensuring that the pressure holding process fully matches the process requirements and preventing the nameplate 4 from not adhering firmly due to insufficient pressure holding time.
[0047] In this embodiment, a pressing cover plate 323 for abutting the nameplate 4 is provided at the drive end of the pressure-holding cylinder 32. Magnetic switches 322, respectively provided at the upper and lower ends of the pressure-holding cylinder 32, can detect the operating status of the pressure-holding cylinder 32, enabling it to work in conjunction with the time relay 8 to achieve automated timing control of the pressure-holding process during nameplate 4 assembly. A pressure regulating valve 7 is provided at the air inlet end of the pressure-holding cylinder 32 to flexibly adjust the pressure according to the actual pressing of the nameplate 4. Furthermore, the pressure-holding cylinder 32 is a dual-axis cylinder, which can limit the radial displacement of the piston rod, ensuring the consistency of the nameplate 4 assembly pressing.
