Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a novel automatic piston rod installation fixture. Background Technology

[0002] The piston rod is a precision transmission component in mechanical engineering that connects the piston and the actuator. It is mainly used to transmit reciprocating motion force in hydraulic / pneumatic systems. Its core functions include power transmission, sealing, and guidance. It is widely used in engineering machinery, automotive braking, and industrial automation.

The fixture includes a base, a motor bracket fixedly mounted on the base, a drive motor fixedly mounted above the motor bracket, and a driven motor fixedly mounted below the motor bracket and connected to the drive motor. A three-jaw chuck for clamping the piston rod upper cover is fixedly connected to the output shaft of the driven motor. A movable support is slidably mounted on the base, and two lower cover fixing supports for clamping the piston rod lower cover are fixedly mounted above the movable support. This device employs both electrical and pneumatic control, resulting in a high degree of automation, high installation efficiency, reduced labor intensity, guaranteed piston rod installation quality, and the ability to achieve stable mass production, thereby improving economic benefits.

Not only is the pre-installation of the upper and lower covers necessary, but after installation, the fixture's limiting effect on the piston rod must be released before it can be removed and reinserted for continued installation.

An arc-shaped clamping plate 14 is provided at the bottom of the top plate 13. The arc-shaped clamping plate 14 is slidably connected in the inner cavity of the U-shaped limiting seat 12. An anti-slip pad 15 is adhered in the arc groove at the bottom of the arc-shaped clamping plate 14. The U-shaped limiting seat 12 is set on the top of the worktable 1 through an adjusting assembly.

[0027] The top of the arc-shaped clamping plate 14 is limited by a bearing and rotatably connected to a fastening stud 16. The top of the fastening stud 16 is fixedly connected to an adjusting handwheel 17. The top of the arc-shaped clamping plate 14 is symmetrically connected to a limiting guide plate 18.

[0028] The working principle of this invention is as follows: After the piston rod to be assembled is placed in the U-shaped limiting seat 12 for limiting, the servo motor 27 on the L-shaped fixing frame 26 drives the adjusting gear 8 outside the limiting rotating shaft 9 to rotate. With the help of the adjusting teeth 10, the limiting ring 5 in the limiting rotating groove 4 and the ball 7 in the ball groove 6, the adjusting ring seat 3 is rotated 180 degrees, thereby rotating the piston rod between the two mounting mechanisms for the installation of the upper and lower covers.

[0029] Example 2;

[0030] Please see Figures 1-3 In this embodiment of the invention, the adjustment component includes an adjustment groove 19 symmetrically opened on the top of the workbench 1.

[0031] The working principle of this invention embodiment is as follows: When the piston rod to be installed with the upper and lower covers is rotated between the installation mechanism through the clamping mechanism, the handwheel 24, in conjunction with the bearing, can drive the bidirectional lead screw 23 to rotate, thereby adjusting the position of the two symmetrical adjustment blocks 20 in the adjustment groove 19. This is to cooperate with the U-shaped linkage seat 21, the linkage shaft 22, and the linkage plate 48. Under the limitation of the limiting frame 11, the height of the U-shaped limiting seat 12 is adjusted, that is, the height of the piston rod is adjusted according to the installation position of the piston rod, to ensure that it can be smoothly installed with the upper and lower covers in the installation mechanism, thereby improving the applicability of this new type of piston rod automatic installation fixture.

[0032] Example 3;

[0033] Please see Figures 4-8 In this embodiment of the invention, the mounting mechanism includes two stabilizing rings 28 fixedly connected to the top of the workbench 1. The inner cavity of the stabilizing rings 28 is rotatably connected to a limiting seat 29. The limiting seat 29 is rotatably connected to the top of the workbench 1 via a limiting post 49. A U-shaped rotating seat 30 is fixedly connected to the top of the limiting seat 29. A dual-axis servo motor 31 is fixedly connected to the inner cavity of the U-shaped rotating seat 30. An adjusting cylinder 32 is provided on the outer ring of the output shafts on both sides of the dual-axis servo motor 31. An installation plate 33 is fixedly connected to one end of the adjusting cylinder 32. A clamping component is provided on one side of the installation plate 33. The limiting post 49 is driven by a driving component 2.

[0034] The output shaft of the dual-axis servo motor 31 has symmetrically opened limit grooves 34 on its outer ring. The inner cavity of the limit groove 34 is slidably connected to the limit block 35. The limit block 35 is fixedly connected to the adjusting cylinder 32. Both sides of the U-shaped rotary seat 30 are symmetrically and fixedly connected to electric push rods 37. The output end of the electric push rod 37 is fixedly connected to the limit plate 36. The mounting plate 33 is located in the inner cavity of the limit plate 36 and the two are rotatably connected. The adjusting cylinder 32 passes through the limit plate 36 and the two are rotatably connected.

[0035] The clamping assembly includes a movable groove 38 formed on one side of the mounting plate 33. The inner cavity of the movable groove 38 is symmetrical and slidably connected to a movable block 39. A clamping arc block 40 is fixedly connected to one side of the movable block 39. A two-way lead screw 42 is rotatably connected to the inner cavity of the movable groove 38. The two-way lead screw 42 passes through two movable blocks 39 and is threaded. The two-way lead screw 42 passes through the mounting plate 33 and the two are limited by a bearing and are rotatably connected. A handwheel 41 is fixedly connected to one end of the two-way lead screw 42.

[0036] The second drive assembly includes an L-shaped fixed frame 43 fixedly connected to the bottom of the worktable 1. A servo motor 44 is fixedly connected to the top of the L-shaped fixed frame 43. The output shaft of the servo motor 44 is fixedly connected to a limit post 49 on one side. A drive sprocket 45 and a driven sprocket 46 are rotatably connected to the bottom of the worktable 1. The drive sprocket 45 and the driven sprocket 46 are connected by a chain 47. Two limit posts 49 pass through the worktable 1 and are fixedly connected to the drive sprocket 45 and the driven sprocket 46 respectively.

[0037] The working principle of this invention is as follows: When the piston rod is pressed and limited within the U-shaped limiting seat 12 and rotated between the two mounting mechanisms, the upper and lower covers to be installed are placed between the clamping arc blocks 40 on one side of the mounting plate 33. Then, the handwheel 41 drives the bidirectional lead screw 42 to rotate, which, in conjunction with the moving block 39 in the moving groove 38, drives the clamping arc block 40 to move, clamping and limiting the upper or lower cover. Next, the electric push rod 37 drives the limiting plate 36, together with the mounting plate 33, to approach the piston rod mounting position, and the dual-axis servo motor 31, in conjunction with the limiting block 35 in the limiting groove 34, drives the mounting plate 33 to rotate, thereby... The upper or lower cover will rotate and be installed at the end of the piston rod. When the upper or lower cover is screwed into the end of the piston rod, the upper or lower cover with the mounting on the other side will be clamped and limited on the mounting plate 33 on the other side. After the previous set of piston rods is installed, the servo motor 44, in conjunction with the drive sprocket 45, the driven sprocket 46 and the chain 47, can drive the two limiting posts 49 to rotate 180 degrees. Under the limit of the stabilizing ring 28, the mounting plate 33 holding the upper or lower cover to be installed will rotate to face the piston rod that is clamped and limited by the clamping mechanism. This is to cooperate with the continuous installation and replacement of piston rods to ensure the installation efficiency of piston rods.

[0038] When using this new type of piston rod automatic installation fixture, the piston rod to be assembled is placed in the U-shaped limiting seat 12. Then, by adjusting the handwheel 17 in conjunction with the bearing, the fastening stud 16 is rotated. Under the action of the top plate 13 and the symmetrically arranged limiting guide plates 18, the arc-shaped clamping plate 14, together with the anti-slip pad 15, moves down to press and contact the piston rod to be installed, thereby pressing and limiting the piston rod in the U-shaped limiting seat 12. Then, the servo motor 27 on the L-shaped fixing bracket 26 drives the adjusting gear 8 outside the limiting rotating shaft 9 to rotate, which in turn works with the adjusting teeth 10 and the limiting ring 5 and ball groove in the limiting rotating groove 4. Under the action of the ball bearing 7 inside 6, the adjusting ring seat 3 is rotated 180 degrees, thereby rotating the piston rod between the two mounting mechanisms for the installation of the upper and lower covers. During the installation process, the above steps are repeated to press and limit the other piston rod within the empty U-shaped limiting seat 12 on the right side. After the upper and lower covers of the previous piston rod are installed, the limiting ring 5 is rotated 180 degrees again to remove the piston rod with the upper and lower covers installed and reinstall the piston rod to be installed. The structure is simple and the operation is convenient. The installation and replacement of piston rods are carried out continuously in this way, which greatly improves the production efficiency of piston rod assembly.
