Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to an assembly fixture that ensures perpendicularity. Background Technology

[0002] In the assembly process of ceramic lamp holders and hardware parts in the light source accessories industry, the riveting surface of the customer's product structure is inclined at 15 degrees to the inner diameter surface of the outer shape, and the pin riveting material adopts the pressing forming process, which makes the force-bearing surface of the pin riveting support prone to deformation and sinking. The traditional single-pin stamping and spin riveting process has significant defects: on the one hand, the single pin is subjected to force at a single point and the bottom mold limit is insufficient, resulting in a large deviation in the perpendicularity between the rivet pin and the ceramic part; on the other hand, a single product needs to be riveted multiple times, resulting in low production efficiency, and products with unqualified perpendicularity cannot meet the customer's automated assembly requirements.

[0003] Existing technical problems: 1. Insufficient verticality accuracy: Traditional processes use single-needle riveting, which causes parts to tilt easily during riveting due to single-point force. In addition, the bottom mold limiting structure is not sufficient and cannot adapt to the 15-degree inclined surface of the product. The final product's verticality deviation exceeds the client's automated production requirements. 2. Low production efficiency: Single-needle riveting requires multiple operations on a single product, which is cumbersome and cannot effectively position and clamp inclined parts, resulting in assembly efficiency far lower than the requirements of automated production. Therefore, it is necessary to design an assembly fixture that ensures verticality to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide an assembly fixture that ensures perpendicularity, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An assembly fixture for ensuring verticality includes a machine base. The upper middle portion of the machine base has a first slide groove and a second slide groove. There are two first slide grooves located on the front and rear sides of the second slide groove. A support plate is fixedly connected to the rear upper part of the machine base. A power supply box is fixedly connected to the lower right end of the support plate. A lifting device is fixedly connected to the middle upper part of the support plate.

A secondary gear is meshed with the upper part of the outer surface of the main gear. A rotating rod is inserted and fixedly connected to the middle of the right end of the secondary gear. A fixing block is fixedly connected to the right end of the rotating rod. An installation groove is opened at the right end of the fixing block. A rotating shaft is movably connected to the middle of the upper and lower blocks of the fixing block. A fixing plate is sleeved on the outer surface of the rotating shaft. Damping springs are fixedly connected to the front and rear of the left end of the fixing plate. Multiple movable holes are opened at the right end of the fixing plate. An airbag block is provided on the left block wall of the fixing plate. Multiple clamping posts are fixedly connected to the right end of the airbag block. The drive motor is fixedly connected to the middle of the left end of the push plate.

[0009] Preferably, the number of the plurality of clamping posts is the same as the number of movable holes, and the clamping posts are interlocked and connected in the movable holes.

[0010] Preferably, the left and right ends of the rotating rod are movably connected to the upper part of the left and right plate walls of the push plate through bearings, respectively. The size of the secondary gear is the same as that of the main gear and is symmetrically distributed vertically. The left ends of the two damping springs are fixedly connected to the front and rear parts of the left block wall of the fixed block, respectively.

[0011] Preferably, the two sliders are slidably connected in the first groove, and both sliders have a U-shaped structure, while the push block is slidably connected in the second groove.

[0012] Preferably, the power supply box is located at the lower right end of the support plate, and the power supply box is connected to the lifting equipment, riveting machine, electric push rod in the clamping mechanism, and drive motor in the connecting assembly via wiring to supply power to each device.

[0013] Preferably, the pusher plate is located above the machine platform and can move laterally along the machine platform, and the pusher plate is rectangular in shape.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, by setting up components such as electric push rod, slider, push block, and push plate, and through the sliding cooperation relationship between the slider and the first slide groove and the push block and the second slide groove, the electric push rod can perform lateral preliminary positioning and clamping of ceramic and hardware parts to be assembled through the groove at the front end of the push plate. Thus, this device can achieve rapid and accurate positioning of parts through the stable transmission of the electric push rod and the slide groove structure, avoiding the perpendicularity problem caused by the deviation of traditional manual positioning and improving the assembly accuracy.

[0016] 2. In this utility model, the drive motor, main gear, secondary gear, fixed plate, airbag block, clamping column, and other components are driven by the meshing transmission of the drive motor and gear transmission structure, and the fixed plate is adjusted by the angle of the rotating shaft. This allows the drive motor to drive the fixed plate to rotate to fit the 15-degree inclined surface of the part. The airbag block is inflated and pushes the clamping column through the movable hole to achieve multi-directional adaptive clamping. Thus, this device can adapt to the inclined surface of the part through gear transmission, and solve the problem that traditional fixtures cannot handle inclined parts through the combination of airbag and clamping column, ensuring the verticality of the product and meeting production requirements.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] An assembly fixture for ensuring verticality includes a machine base 1. The upper middle part of the machine base 1 has a first slide groove 8 and a second slide groove 9 respectively. There are two first slide grooves 8 located on the front and rear sides of the second slide groove 9. A support plate 3 is fixedly connected to the rear part of the upper end of the machine base 1. A power supply box 4 is fixedly connected to the lower right end of the support plate 3. A lifting device 5 is fixedly connected to the middle part of the upper end of the support plate 3. An equipment frame 2 is fixedly connected to the lower end of the lifting device 5. A riveting machine 6 is inserted through the upper end of the equipment frame 2. A clamping mechanism 7 is fixedly connected to the middle part of the left end and the middle part of the right end of the machine base 1.

[0027] In this embodiment, the clamping mechanism 7 includes an electric push rod 71. The output end of the electric push rod 71 passes through the machine base 1 and is fixedly connected to a push plate 72. The front end of the push plate 72 has a groove 73. The front and rear lower ends of the push plate 72 are both fixedly connected to sliders 74. The middle lower end of the push plate 72 is fixedly connected to a push block 75. The left end of the push plate 72 is fixedly connected to a connecting component 76. The electric push rod 71 is fixedly connected to the left and right ends of the machine base 1 respectively. The two sliders 74 are slidably connected in the first slide groove 8 respectively, and the sliders 74 are all U-shaped. The push block 75 is slidably connected in the second slide groove 9. The push plate 72 is located above the machine base 1 and can move laterally along the machine base 1. The push plate 72 is rectangular.

[0028] The above scheme involves activating electric push rods 71 ​​fixedly connected to both ends of the machine base 1. The output end of the electric push rod 71 passes through the machine base 1 and pushes a rectangular plate-shaped push plate 72. The U-shaped sliders 74 at the front and rear of the lower end of the push plate 72 slide in the first slide groove 8, and the push block 75 at the middle of the lower end slides in the second slide groove 9. This allows the push plate 72 to move laterally along the machine base 1. The groove 73 at the front end of the push plate 72 is used to initially position and clamp the ceramic and hardware parts to be assembled on the machine base 1. During this process, the electric push rod 71 provides a stable pushing force. The sliders 74 and push blocks 75, in conjunction with the slide groove design, ensure the smooth movement of the push plate 72 and prevent the parts from shifting during movement. This not only achieves rapid and effective initial positioning of the parts, but also greatly improves assembly efficiency compared to the traditional manual positioning method, reduces product verticality deviation caused by inaccurate positioning, and thus improves the accuracy and quality of product assembly.

[0029] In this embodiment, the connecting component 76 includes a drive motor 761. The output end of the drive motor 761 passes through the push plate 72 and is fixedly connected to a main gear 762. A secondary gear 763 is meshed with the upper part of the outer surface of the main gear 762. A rotating rod 764 is inserted and fixedly connected to the middle of the right end of the secondary gear 763. A fixing block 765 is fixedly connected to the right end of the rotating rod 764. A mounting groove 766 is opened at the right end of the fixing block 765. A rotating shaft 769 is movably connected to the middle of the upper and lower blocks of the fixing block 765. A fixing plate 767 is sleeved on the outer surface of the rotating shaft 769. A damping spring 768 is fixedly connected to the front and rear of the left end of the fixing plate 767. A plurality of movable holes 7610 are opened at the right end of the fixing plate 767. An airbag block 7611 is provided on the left block wall of the fixing plate 767. The right end of the airbag block 7611 is fixed. Multiple clamping posts 7612 are fixedly connected. The drive motor 761 is fixedly connected to the middle of the left end of the push plate 72. The number of clamping posts 7612 is the same as the number of movable holes 7610, and the clamping posts 7612 are inserted into the movable holes 7610 one by one. The left and right ends of the rotating rod 764 are respectively movably connected to the upper part of the left plate wall and the upper part of the right plate wall of the push plate 72 through bearings. The secondary gear 763 has the same size as the main gear 762 and is symmetrically distributed vertically. The left ends of the two damping springs 768 are respectively fixedly connected to the front part of the left block wall and the rear part of the left block wall of the fixed block 765. The power supply box 4 is located at the lower right end of the support plate 3, and the power supply box 4 is connected to the lifting device 5, the riveting machine 6, the electric push rod 71 in the clamping mechanism 7, and the drive motor 761 in the connecting assembly 76 through a line to supply power to each device.

[0030] Through the above scheme: after the part is initially positioned on the machine tool 1, the power supply box 4 supplies power to the drive motor 761 in the connecting assembly 76. The drive motor 761 starts, and its output end drives the main gear 762 to rotate. Since the main gear 762 meshes with the secondary gear 763, and the two are the same size and symmetrically distributed vertically, the secondary gear 763 rotates accordingly. Through the rotating rod 764, it drives the fixing block 765 to rotate. The fixing block 765 adjusts the angle of the fixing plate 767 through the rotating shaft 769, so that it fits the inclined surface of the part. Then, the airbag block 7611 inflates and pushes multiple clamping columns 7612 through the movable hole 7610, accurately clamping the part from multiple directions. During the process, the damping spring 768 plays a buffering role to avoid excessive clamping force from damaging the part. To maintain the stability of the fixed plate 767, the drive motor 761 and gear transmission structure enable the fixed plate 767 to rotate flexibly, allowing it to adapt to the surface of parts at different angles. The combination of the airbag block 7611 and the clamping column 7612 can adaptively extend and retract according to the shape of the part, achieving tight clamping. The damping spring 768 enhances the stability of the clamping process. Compared with traditional fixtures, this connecting component 76 can not only accurately fix inclined parts, effectively solving the problem that traditional fixtures cannot handle inclined parts, but also greatly improve the reliability of part fixing through multi-directional and adaptive clamping methods, thereby ensuring the verticality of product assembly, meeting the strict requirements of customer automated production for product precision, and significantly improving production efficiency and product quality.

[0031] It should be noted that this utility model is an assembly fixture that ensures verticality. First, the ceramic and hardware parts to be assembled are placed on the machine base 1. The power supply box 4 provides power to the lifting device 5, the riveting machine 6, the electric push rod 71 in the fixture mechanism 7, and the drive motor 761 in the connecting assembly 76. When the electric push rod 71 is started, its output end pushes the push plate 72. The slider 74 at the lower end of the push plate 72 slides in the first slide groove 8, and the push block 75 slides in the second slide groove 9, causing the push plate 72 to move laterally left and right, pushing the parts towards the center for initial positioning. Then, the drive motor 761 is started, and its output end drives the main gear 762 to rotate. The main gear 762 meshes with the secondary gear 763. The secondary gear 763 drives the fixed block 765 to rotate via the rotating rod 764, thereby adjusting the angle of the fixed plate 767 to fit the inclined surface of the part. Then, the airbag block 7611 inflates and expands, pushing multiple clamping columns 7612 to extend and retract within the movable hole 7610 according to the shape of the part, firmly clamping the part from multiple directions. At the same time, the damping spring 768 provides buffering and stabilizing effects to prevent excessive clamping force from damaging the part. After the part is accurately fixed, the lifting device 5 drives the equipment frame 2 and the riveting machine 6 to descend, so that the riveting machine 6 is aligned with the part assembly position to perform the riveting operation, ultimately achieving high-precision vertical assembly, improving product quality and production efficiency, and meeting the production needs of the client.
