Hello everyone this is my first instuctable, I hope you like it.
This is a linear actuator which I have designed ,its a very low cost actuator ,you can use it for many applications.
it is a powerful actuator it can easily lift 3 to 5 kilogram weight but ,I think it can lift even more weight.
it can easily push 5 to 7 kilogram of weight or even more .
considering its made up of glue stick ,at first I thought that glue sticks are not that strong but trust me they are ,if they are properly aligned and used with high torque geared motors.
this actuator has a 4 cm to 4.5 cm linear displacement.
it can be used for many applications like lifting,pulling and pushing.
you can use it for your robots etc.
I hope you have fun making this linear actuator.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Material List
- 2 x Glue Stick
- 2 x Small Plastic Tube
- 2 x Geared Motor (300 rotations per minute)
- 2 x Motor Mounting Bracket
- 2 x Small Plastic Gears
- 4 x Thin Metal Strip With holes
- 2 x Large Bolts
- 2 x Big Washers
- 30 x Small Bolts
- 30 x Nuts
- 60 x Small Washers
- Aluminium Angle
- Thin Aluminium Bar
Step 2: Creating the Actuators
You will need a small 8 cm long strong plastic tube ,a glue stick and a small plastic gear which can be attached to the base of glue stick and you have to remove the glue from the stick so that you can get the plastic part which holds the glue.
- Stick the plastic tube and the plastic part which holds the glue with any strong adhesive.
- Stick the small plastic gear at the bottom of the glue stick with any strong adhesive .
- Now put the plastic tube inside the glue stick.
- Now you have a very basic looking linear actuator.
- Follow all the images to understand better.
Step 3: The Actuator Chassis
Here is a look how the chassis will look after completion.
Step 4: Making the Main Support for Chassis
- This is the main angle piece ,as the complete structure is supported by it.
- Cut a 15 cm long piece of aluminium angle.
- You can use a metal filer to soften the sharp edges.
- Now drill holes in the aluminium as shown in the image.
- Now your main supporting aluminium piece is ready.
Step 5: Cutting Side Pieces
- You need to cut two of these pieces.
- Cut two 12.8 cm piece of aluminium angle .
- Use a metal filer to soften the sharp edges.
- Now drill holes in the aluminium angles as shown in image (sorry I drilled these holes very roughly ).
- The image shown in this step is of a single angle with different sides as drilling the holes is required on both sides of the angle.
- Their should be two of these aluminium angle pieces and they need to be exactly same.
- Now your side aluminium angle pieces are ready.
Step 6: Attaching the Side Pieces With the Main Piece
- After cutting the main aluminium piece and side aluminium pieces we will attach them together using nuts and bolts.
- Attach the left and right aluminium piece as shown in the image.
- Attach the motor mounting brackets on the main aluminium piece.
- Now mount the motors on motor mounting brackets with proper alignment.
- Your basic chassis is ready now
Step 7: Placing and Aligning the Glue Sticks in the Chassis
- This is the most important step as our complete linear actuator depends on this step.
- We need two 5 cm long aluminium angle pieces.
- Now we will attach our glue stick with a 5 cm long aluminium angle pieces using thin metal strips with holes as Shown in the image.
- Now we will place the complete assembly in our chassis as shown in image.
- Now we will make the supporting structure for our plastic tubes.
Step 8: Making the Supporting Structure for Our Plastic Tube.
- To make the support for our plastic tubes we need to cut a 13.5 cm aluminium angle.
- Now we need to drill holes on both the sides of aluminium angle.
- Now we have to cut four 12 cm long thin aluminium bar and drill holes in them as shown in the image.
- In this step we will use only two thin 12 cm long aluminium bar ,the other two are for next step.
- Now we will attach these 12 cm long aluminium bars with our 13.5 cm long aluminium angle as shown in image.
- Now the next step is to attach aluminium angle with the two plastic tubes as shown in image.
- To attach plastic tubes with aluminium angle we can use large bolts to hold the plastic tubes in place with aluminium angle. and now your plastic tube support is ready.
Step 9: Finalising the Actuator
- This is the last step for our actuator.
- Now we will attach the previously made plastic tube supporting structure with our actuator chassis.
- Now cut four 6 cm long thin aluminium bar.
- Now attach the previously cut two 12 cm aluminium bar with 6 cm bar as shown in image ,this is used to hold and align the plastic tube support structure with chassis.
- Your actuator is ready.
Step 10: Actuator Is Ready
- Now we will paint the actuator.
- Now our actuator is complete and ready.
