Description

Technical Field

[0001] This utility model relates to the field of bolt pressing technology, and in particular to a bolt vertical pressing mechanism that prevents deflection. Background Technology

[0002] Anti-deflection bolt vertical pressing mechanisms are widely used in high-precision fields such as automobile manufacturing, mechanical assembly, and aerospace. For example, in the assembly of automobile engine cylinder blocks and cylinder heads, bolts need to be pressed in vertically with precision to ensure sealing and connection strength. In precision mechanical assembly, bolt deflection can be avoided, ensuring the fit accuracy of parts and the stability of equipment.

[0003] The existing bolt press-in structure includes a base, a linear drive component, and a pressure rod. The end of the pressure rod has a groove to fit the bolt head. Its structure is intuitive, compact, and modular, allowing it to be directly fixed to the production line table. Its advantages are: simple construction, few core components, direct connection, easy assembly, and quick production; low cost, no need for complex components, suitable for widespread adoption; fast response, with rapid extension and retraction of the drive component, enabling efficient single press-in in simple scenarios.

[0004] However, the existing structure has significant drawbacks: poor anti-deflection effect; due to the lack of effective guide and limit, it is easily affected by external forces or deviations, causing bolt tilting and affecting connection quality; low pressing accuracy, making it difficult to control depth and perpendicularity, resulting in uneven assembly quality; and weak adaptability, requiring complex adjustments for bolts of different specifications, reducing production flexibility. Therefore, an anti-deflection bolt vertical pressing mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bolt vertical pressing mechanism to prevent deflection, aiming to improve the problems of poor anti-deflection effect and low pressing accuracy in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bolt vertical pressing mechanism to prevent deflection, comprising a placement shell, wherein a pressing mechanism is provided on the top of the placement shell and a clamping mechanism is provided on the side wall of the placement shell;

[0007] The pressing mechanism includes a pressing rod and a limiting plate. The side wall of the pressing rod is slidably connected to the inside of the placement shell. The side wall of the limiting plate is slidably connected to the inside of the placement shell. An electric push rod is provided at the upper end of the placement shell.

One end of the spring is fixedly connected to the side wall of the support rod, and the other end of the spring is fixedly connected to the side wall of the placement shell.

[0008] As a further description of the above technical solution:

[0009] Both support rod one and support rod two are slidably connected to the inside of the outer shell, and support rod one and support rod two are staggered.

[0010] As a further description of the above technical solution:

[0011] The side wall of the pressing rod is fixedly connected to one side wall of the limiting plate, and the side wall of the pressing rod is slidably connected inside the outer shell.

[0012] As a further description of the above technical solution:

[0013] The clamping mechanism includes a clamping plate and a connecting rod. The side wall of the clamping plate is slidably connected to the inside of the placement shell. The side wall of the connecting rod is slidably connected to the inside of the first support rod. The first support rod has a first fixing rod inside it.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the bolt is placed in the housing and clamped by the clamping plate to prevent deflection. Then, the electric push rod is activated to drive the pressing rod to press down, causing the support rod one and support rod two on the pressing rod to move downward. This causes the spring to be compressed and tightened, which drives the limiting plate one to press the bolt vertically. This improves the problem of the vertical pressing angle changing and realizes the function of vertical pressing of the bolt.

[0022] 2. In this utility model, when pressed down, the connecting rod on the first support rod is pressed down and slides outward, driving the connected pull rod to move outward of the placement shell, thereby causing the clamping plate to move outward. At the same time, the slider connected to the pull rod slides within the second limiting plate. The clamping plate is prevented from sliding out under the action of the second limiting plate. After the bolt is pressed, the electric push rod is activated to reset the spring, and the pressing rod moves upward. Under the action of the first limiting plate, it is prevented from sliding out of the placement shell. At the same time, the clamping plate returns to the placement shell. This improves the problem of bolts easily deflecting and realizes the function of clamping the bolt. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-6This utility model provides an embodiment of a bolt vertical pressing mechanism to prevent deflection, comprising a placement shell 1, with a pressing mechanism at the top of the placement shell 1. The pressing mechanism is used to vertically press the bolt into a designated position to realize the bolt installation action and ensure the accuracy of the pressing process. A clamping mechanism is provided on the side wall of the placement shell 1. The clamping mechanism is used to clamp and fix the bolt or the workpiece to be installed to prevent it from deviating during the pressing process and improve the stability of the installation. The pressing mechanism includes a pressing rod 4 and a limiting plate 9. The side wall of the pressing rod 4 is slidably connected inside the placement shell 1. The pressing rod 4 is used to directly transmit pressure to the bolt and push the bolt to perform the pressing movement. Its sliding connection method ensures the linearity of the movement. The side wall of the limiting plate 9 is slidably connected inside the placement shell 1. The limiting plate 9 is used to limit the movement trajectory of the pressing rod 4 to prevent it from deviating laterally during the sliding process and to ensure the verticality of the pressing direction.

[0033] An electric push rod 2 is installed at the upper end of the housing 1, and a fixing plate 3 is installed at the upper end of the housing 1. The fixing plate 3 is used to fix the position of the electric push rod 2 so that it will not shake or shift during operation, ensuring the stability of power output. The output end of the electric push rod 2 passes through the fixing plate 3 and is fixedly connected to the side wall of the pressing rod 4. A support rod 6 and a support rod 17 are fixedly connected to the side wall of the pressing rod 4. A housing 5 is installed on the side wall of the support rod 6. Springs 8 are fixedly connected to the side walls of both the support rod 6 and the support rod 17. The springs 8 are used to buffer the impact force on the support rod during movement, reduce the impact of vibration on the entire mechanism, and extend the service life of the components. One end of the spring 8 is fixedly connected to the side wall of the support rod 6, and the other end of the spring 8 is fixedly connected to the side wall of the housing 1. The other end of the spring 8 is fixedly connected to the side wall of the housing 1. The spring 8, together with the support rod 1 and the housing 1, performs elastic telescopic movement. When the support rod moves, the spring 8 undergoes elastic deformation, absorbing some kinetic energy and achieving a buffering and shock absorption effect. The side walls of the support rod 1 and the support rod 2 are slidably connected inside the housing 5, and the support rod 1 and the support rod 2 are staggered. The side wall of the pressing rod 4 is fixedly connected to the side wall of the limiting plate 19. The pressing rod 4 moves synchronously with the limiting plate 19. The limiting plate 19 slides along with the pressing rod 4, always restricting the direction of movement of the pressing rod 4, further ensuring the verticality of the pressing process. The side wall of the pressing rod 4 is slidably connected inside the housing 5. The pressing rod 4 moves in conjunction with the housing 5, and the housing 5 acts as a barrier to the lateral displacement of the pressing rod 4.

[0034] Reference Figures 2-5The clamping mechanism includes a clamping plate 13 and a connecting rod 10. The side wall of the clamping plate 13 is slidably connected inside the placement shell 1. The clamping plate 13 slides in conjunction with the placement shell 1, and the placement shell 1 provides a movement track for the clamping plate 13, ensuring that the clamping plate 13 can only move in a specified direction and guaranteeing the accuracy of the clamping action. The side wall of the connecting rod 10 is slidably connected inside the support rod 6. The connecting rod 10 slides in conjunction with the support rod 6. The movement of the support rod 6 drives the connecting rod 10 to move synchronously, transmitting power to subsequent components and realizing the linkage of the clamping mechanism. A fixing rod 7 is provided inside the support rod 6 to limit the movement of the connecting rod 10. The movement range is controlled to prevent the connecting rod 10 from detaching from the support rod 6 during sliding, ensuring stable and reliable force transmission. A pull rod 11 is fixedly connected to the side wall of the clamping plate 13. The pull rod 11 connects the clamping plate 13 and the connecting rod 10, transmitting the force from the connecting rod 10 to the clamping plate 13, causing the clamping plate 13 to clamp or loosen. A second fixing rod 12 is installed inside the pull rod 11, connecting the pull rod 11 and the connecting rod 10 to ensure stable relative movement between them, preventing detachment or displacement during force transmission. The side wall of the second fixing rod 12 is slidably connected inside the connecting rod 10, and the second fixing rod 12 cooperates with the connecting rod 10 to slide. In the motion, when the connecting rod 10 moves, the fixed rod 12 slides within the connecting rod 10, driving the pull rod 11 to move synchronously, thus achieving effective force transmission; a slider 14 is fixedly connected to the side wall of the pull rod 11, and a limit plate 15 is fixedly connected to the side wall of the housing 1. The side wall of the limit plate 15 has a groove 16, and the slider 14 is slidably connected inside the groove 16; the slider 14 slides in cooperation with the groove 16, and the guiding effect of the groove 16 causes the slider 14 to drive the pull rod 11 to move along a fixed direction, ensuring that the clamping action of the clamping plate 13 is stable and orderly; the side walls of the two support rods 6 have slots, and the side walls of the fixed rod 7 are fixedly connected to the slots. Inside the slot; the slot works with the fixing rod 7 to position and install the fixing rod 7, ensuring that the fixing rod 7 can stably limit the movement of the connecting rod 10; the side walls of the pull rods 11 on both sides have slots, and the side walls of the fixing rod 12 are fixedly connected inside the slots; the slots work with the fixing rod 12 to fix the fixing rod 12, ensuring that the fixing rod 12 is stable in position during force transmission; the inner wall of the fixing plate 3 is fixedly connected to the side wall of the electric push rod 2, and the side wall of the outer shell 5 is fixedly connected to the side wall of the placement shell 1. The outer shell 5 works with the placement shell 1 to fix the outer shell 5, so that the outer shell 5 can stably provide protection and guidance for the internal components.

[0035] Working principle: When using this equipment, first fix the equipment with the fixing plate 3, then put the bolt into the housing 1 and clamp it with the clamping plate 13 to prevent deflection. Then, start the electric push rod 2 to drive the pressing rod 4 to press down, so that the support rod 1 6 and support rod 2 17 on the pressing rod 4 move downward, so that the spring 8 is compressed and tightened under the action of force, and drives the limiting plate 1 9 to press the bolt vertically.

[0036] While pressing down, the connecting rod 10 on the support rod 6 slides outward under the action of the support rod 6, thereby driving the pull rod 11 connected to it to move outward of the placement shell 1, thereby driving the clamping plate 13 to move outward. At the same time, the slider 14 connected to the pull rod 11 slides inside the limiting plate 15. The clamping plate 13 is prevented from sliding out under the action of the limiting plate 15. After pressing the bolt, the electric push rod 2 is activated to reset the spring 8. The pressing rod 4 moves upward and is prevented from sliding out of the placement shell 1 under the action of the limiting plate 9.
