Description

Technical Field

[0001] This utility model relates to the field of cylinder actuator technology, specifically an auxiliary device that can simultaneously press-fit multiple springs inside the cylinder head. Background Technology

[0002] Cylinder actuators can be divided into two main categories: double-acting and single-acting. Single-acting actuators are double-acting cylinder actuators with a safety return spring, and they are also a replacement product designed to address some weaknesses of spring-operated diaphragm actuators. They can withstand high air pressure, have large thrust, fast stroke speed, and are robust and durable.

[0003] The existing process generally uses the method of tightening the cylinder head fastening screws in sequence to press the spring inside the cover. Because the four fastening screws need to be tightened one by one, the cylinder head may lift up, causing the spring inside the cylinder head to move around or come out, which affects the output and quality of the actuator. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides an auxiliary device that can simultaneously press-fit multiple springs inside the cylinder head. This device solves the problem of the cylinder head lifting when tightening the fastening screws.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] This utility model discloses an auxiliary device for synchronously pressing multiple springs inside a cylinder head, comprising a worktable, which is hollow in shape, with a base fixedly connected to the worktable. Four vertically arranged uprights are arranged around the base, with the lower ends of the uprights extending through the upper surface of the worktable into its interior. The uprights slide against the worktable. A pressing plate is provided at the upper end of each upright, and the pressing plate is fixedly fitted to the upright. The pressing plate has multiple mounting holes corresponding to fastening screws on the cylinder head. A drive mechanism is provided inside the worktable for driving the uprights to move vertically.

[0007] In the above solution, by setting up a pressure plate, the actuator is first placed on the base, and the drive mechanism drives the upright to move vertically downward until the cover plate abuts against the cylinder head of the actuator, thereby pre-pressing the cylinder head. At this time, the multiple springs inside the cylinder head are pressed synchronously. Then, the fastening screws are tightened by a hand drill or other equipment to complete the installation, thus solving the problem of the cylinder head lifting when tightening the fastening screws.

[0008] The base includes a fixed seat and a movable seat. The fixed seat is located on the worktable and is fixedly engaged with the worktable. The inner walls on both sides of the fixed seat are provided with grooves. The outer walls on both sides of the movable seat are provided with protrusions that match the grooves. The fixed seat and the movable seat are slidably engaged.

[0009] The above solution uses a movable base to create a pull-out structure, allowing for the selection of a suitable movable base to accommodate various cylinder models.

[0010] The fixed seat has a first threaded hole on its side wall, and the movable seat has a second threaded hole corresponding to the first threaded hole on its side wall. The fixed seat and the movable seat are fixedly connected by a locking pin passing through the first threaded hole and the second threaded hole. When the locking pin is released, the fixed seat and the movable seat are slidably engaged.

[0011] In the above solution, the locking pin is used to fix the movable seat to the fixed seat by inserting the locking pin, and the movable seat can be quickly pulled out and replaced by pulling out the locking pin.

[0012] The drive mechanism includes a rotating rod and a servo motor. A fixed plate is fixedly connected to the lower end of the section of the upright that extends into the workbench. A central hole is provided on the fixed plate, through which the rotating rod passes. The rotating rod and the fixed plate are in a rotating engagement. A drive wheel is connected to the output shaft of the servo motor, and a driven wheel is provided at the upper end of the rotating rod. A belt is sleeved on the drive wheel and the driven wheel.

[0013] In the above scheme, by setting up a drive mechanism, the servo motor is turned on. The output shaft of the servo motor drives the drive wheel to rotate, which in turn drives the driven wheel to rotate via a belt. This causes the rotating rod to rotate, thereby driving the fixed plate to move vertically. Finally, the upright rod moves vertically downward until the cover plate abuts against the cylinder head of the actuator, thus achieving the pre-tightening of the cover plate against the cylinder head.

[0014] A cover plate is provided on the lower end face of the pressing plate, and the cover plate is slidably engaged with the pressing plate.

[0015] The above solution uses a cover plate that can be pulled out from the press plate, making it easy to replace the appropriate cover plate according to the model of the actuator.

[0016] Pressure sensors are installed on both sides of the press plate.

[0017] The above solution uses a pressure sensor to measure the clamping force during the pressing process. By measuring the difference between the preset clamping force and the actual measured clamping force, it can quickly determine whether there are discrepancies in the quantity and quality of springs inside the cylinder head, thus preventing related quality problems from occurring.

[0018] The above solution has the following advantages:

[0019] 1. The auxiliary device for synchronously pressing multiple springs inside a cylinder head according to this utility model includes a worktable, a base fixedly connected to the worktable, and four vertically arranged uprights around the base. The lower ends of the uprights extend through the upper surface of the worktable into the worktable, and the uprights slide against the worktable. A pressing plate is provided at the upper end of the uprights, and the pressing plate is fixedly fitted with the uprights. The pressing plate has multiple mounting holes, which correspond to the fastening screws on the cylinder head. A drive mechanism is provided inside the worktable to drive the uprights to move vertically. With the setting of the pressing plate, the actuator is first placed on the base, and the drive mechanism drives the uprights to move vertically downward until the cover plate abuts against the cylinder head of the actuator, thereby pre-pressing the cylinder head. At this time, the multiple springs inside the cylinder head are synchronously pressed. Then, the fastening screws are tightened by a pistol drill or other equipment to complete the installation.

[0020] 2. The base consists of a fixed seat and a movable seat. The fixed seat and the movable seat are slidably engaged, making the base a pull-out structure. The appropriate movable seat can be selected according to different cylinder bodies to adapt to various cylinder body models. With the setting of the locking pin, the movable seat can be fixed to the fixed seat by inserting the locking pin, and the movable seat can be quickly pulled out and replaced by pulling out the locking pin.

[0028] 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.

[0029] In specific embodiment 1, such as Figures 1-3 As shown, the auxiliary device for synchronously pressing multiple springs inside a cylinder head according to this utility model includes a workbench 1, which is hollow. A base is fixedly connected to the workbench 1, and four vertically arranged uprights 2 are arranged around the base. The lower ends of the uprights 2 penetrate the upper surface of the workbench 1 and extend into the workbench 1, and the uprights 2 and the workbench 1 are in a sliding fit. A pressing plate 3 is provided at the upper end of the uprights 2, and the pressing plate 3 is in a fixed fit with the uprights 2. The pressing plate 3 is provided with multiple mounting holes 4, which correspond to the fastening screws 5 on the cylinder head. A drive mechanism is provided inside the workbench 1 to drive the uprights 2 to move vertically. First, the actuator is placed on the base, and the drive mechanism drives the uprights 2 to move vertically downward until the cover plate 16 abuts against the cylinder head of the actuator, thereby pre-pressing the cylinder head. At this time, the multiple springs inside the cylinder head are synchronously pressed. Then, the fastening screws 5 are tightened by a pistol drill or other equipment to complete the installation.

[0030] like Figure 4 As shown, the drive mechanism includes a rotating rod 11 and a servo motor 12. A fixed plate 13 is fixedly connected to the lower end face of the section of the upright 2 that extends into the worktable 1. The fixed plate 13 has a central hole through which the rotating rod 11 passes, and the rotating rod 11 and the fixed plate 13 are in a rotating engagement. A drive wheel 14 is connected to the output shaft of the servo motor 12, and a driven wheel 15 is provided at the upper end of the rotating rod 11. A belt is fitted onto the drive wheel 14 and the driven wheel 15. When the servo motor 12 is turned on, the output shaft of the servo motor 12 drives the drive wheel 14 to rotate, which in turn drives the driven wheel 15 to rotate via the belt, causing the rotating rod 11 to rotate. This causes the fixed plate 13 to move vertically, and finally causes the upright 2 to move vertically downward until the cover plate 16 abuts against the cylinder head of the actuator, thereby achieving the pre-tightening of the cover plate 16 against the cylinder head.

[0031] In a specific embodiment 2, such as Figure 1 , 5As shown, the difference between this embodiment and Embodiment 1 is that the base in this embodiment includes a fixed seat 6 and a movable seat 7. The fixed seat 6 is located on the workbench 1 and is fixedly engaged with the workbench 1. Grooves 8 are provided on the inner walls on both sides of the fixed seat 6, and protrusions 9 that match the grooves 8 are provided on the outer walls on both sides of the movable seat 7. The fixed seat 6 and the movable seat 7 are slidably engaged. A first threaded hole is provided on the side wall of the fixed seat 6, and a second threaded hole corresponding to the first threaded hole is provided on the side wall of the movable seat 7. The fixed seat 6 and the movable seat 7 are fixedly connected by passing a locking pin 10 through the first threaded hole and the second threaded hole. When the locking pin 10 is released, the fixed seat 6 and the movable seat 7 are slidably engaged. The movable seat 7 makes the base a pull-out structure, and a suitable movable seat 7 can be selected according to different cylinders to adapt to various cylinder models. The movable seat 7 can be fixed to the fixed seat 6 by inserting the locking pin 10, and the movable seat 7 can be quickly pulled out and replaced by pulling out the locking pin 10.

[0032] A cover plate 16 is provided on the lower end face of the pressure plate 3. The cover plate 16 is slidably engaged with the pressure plate 3, so that the cover plate 16 can be pulled out from the pressure plate 3, making it convenient to replace the appropriate cover plate 16 according to the model of the actuator.

[0033] In specific embodiment 3, the difference between this embodiment and embodiments 1 and 2 is that pressure sensors are provided on both sides of the pressing plate 3 to measure the pressing force during the pressing process. By measuring the difference between the preset pressing force and the actual measured pressing force, it is quickly determined whether there is a discrepancy in the quantity and quality of the springs in the cylinder head, thus preventing the occurrence of related quality problems.

[0034] During operation, first select the appropriate moving plate and cover plate 16 according to the cylinder model, and install them on the fixed plate 13 and the pressing plate 3 respectively. Place the cylinder on the base, turn on the servo motor 12, and the output shaft of the servo motor 12 drives the drive wheel 14 to rotate. Through the belt, the driven wheel 15 rotates, causing the rotating rod 11 to rotate, thereby driving the fixed plate 13 to move downward in the vertical direction. Finally, the upright rod 2 moves downward in the vertical direction until the cover plate 16 abuts against the cylinder head of the actuator, thereby achieving the pre-pressing of the cover plate 16 against the cylinder head. Then, tighten the fastening screws 5 with a pistol drill or other equipment to complete the installation.
