This guide covers the complete process of assembling an industrial sewing machine table designed for submerged-head units, from unpacking to motor installation and final adjustments.
1. Starting the Assembly
The table consists of two primary components:
-
The main tabletop
-
The adjustable platform for the sewing machine head
The platform is equipped with multiple pre-drilled holes, ensuring compatibility with various sewing machine models. Elongated horizontal slots allow mounting of motor brackets for different machine configurations.
Five central holes are designed to secure the platform to the tabletop structure. Mounting pins enable both vertical and lateral adjustment of the platform, ensuring precise alignment during installation.
2. Mounting Hardware Overview
All necessary fasteners and fittings are included in the table package.
Begin by inserting the mounting pins into the pre-drilled support holes on the tabletop. Secure each pin with large-diameter washers for added stability. It’s recommended to prepare all washer stacks in advance for more efficient assembly.
Short bolts may be used to attach the motor bracket, if required. Once the hardware preparation is complete, you can move on to the main table assembly.
3. Installing the Platform
Thread a nut onto each mounting pin, add a washer, and insert the pin into the tabletop slot to secure it. Use a 13 mm wrench to tighten the nuts firmly. Repeat the process for all mounting positions.
After all mounting pins are in place, build the washer stack on each pin: add a second nut, followed by a small washer and a large washer. These mounts will support the adjustable platform.
Install three mounts on one side of the table and two mounts on the opposite side. If a motor is required, install it before placing the platform.
Insert three platform bolts and secure them with rubber washers underneath. Use the remaining hardware to complete the platform installation by attaching large, medium, and small washers in sequence and securing them with a nut.
While the platform is inverted, do not fully tighten the nuts — leave room for height adjustment.
4. Motor Installation
Unpack and prepare the motor for installation. Mount the motor base onto the designated brackets. The base features slotted holes for forward and backward adjustment.
Align the motor so that the V-belt falls within the center of the belt slot in the platform. A temporary alignment chain can help with centering. Once aligned, fasten the motor base in this position.
Use a washer and a vibration damper ring, securing them with a nut. If holes do not align perfectly, adjust the motor mounts within the platform slots. Secure the motor using three mounting points, and tighten all nuts with a 14 mm wrench or ratchet.
Tighten the nuts until the vibration damper compresses to approximately 50% of its height.
Pre-install the drive belt for convenience. Install the protective belt guard over the belt, but do not fully tighten it until final alignment. Once the sewing head is mounted and the belt tensioned, adjust and fully tighten the guard.
5. Measuring and Marking
Mount drawer rails approximately 1 inch (25 mm) from the tabletop edge. Determine a suitable position for installing the machine’s power switch.
Unpack and prepare the leg assemblies. Mark leg mounting positions approximately 1 to 1.5 inches (25–38 mm) from the tabletop edge.
Secure the legs, drawer, and power switch according to the marked locations.
6. Final Assembly
Once all components are installed, flip the table unit upright to complete the sewing head installation.
With proper assembly, the submerged sewing table will ensure stable machine positioning, ergonomic operation, and easy access to all controls and attachments.
