Description

Technical Field

[0001] This utility model relates to the field of wooden chair processing technology, specifically an adjustable clamping fixture for wooden chair processing. Background Technology

[0002] A wooden chair is a chair made of wood. Its shape features a wide, straight backrest, a relatively long headrest, a slightly curved back panel, and a seat with a "step-up" stretcher, meaning the footrest is the lowest stretcher, the sides are slightly higher, and the back stretcher is the highest. Clamping fixtures are used in the production of wooden chairs to assist external processing devices.

[0003] A search revealed Chinese patent application number 202220810578.3, which discloses a fixing clamp for wooden chair production, relating to the field of wooden chair processing and manufacturing technology. The clamp includes an inner rubber plate and a metal panel. The inner rubber plate is fixed to the upper inner middle position of the metal panel. A left-side abutment fixing device is provided on the left side of the inner rubber plate on the metal panel, and a right-side abutment fixing device is provided on the right side of the inner rubber plate on the metal panel. An outer stop block is provided on the upper front side of the metal panel, and a telescopic support is provided at the lower rear corner of the metal panel. This invention, by incorporating a rotating support and a telescopic support structure, facilitates stable support of the metal panel for use and allows for easy adjustment of the metal panel's tilt angle, thus enabling convenient fixing according to usage needs. This makes operation and fixing more convenient, and the left-side abutment fixing structure facilitates clamping and fixing.

[0004] The aforementioned patent has a limited range of adjustment for the clamped wooden chair parts, making it impossible to adjust the position of the wooden chair parts in all directions. This results in poor processing flexibility of the external processing device for the wooden chair parts, requiring multiple re-clamping operations to complete the processing of the wooden chair parts, reducing the processing efficiency of the wooden chair parts, and also making the clamping fixture less practical.

[0005] To address this issue, we propose an adjustable clamping fixture for wooden chair processing. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide an adjustable clamping fixture for processing wooden chairs, addressing the shortcomings of the prior art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable clamping fixture for processing wooden chairs, including a base plate, a support plate above the base plate, an adjustment mechanism on the top of the support plate, the adjustment mechanism including a column, a groove, an electric push rod one, and a circular plate, the column being rotatably connected to the top of the support plate via a bearing, the groove being formed on the top of the column, the electric push rod one being fixedly installed inside the groove, and its output end being fixedly connected to the bottom of the circular plate, the top of the circular plate being provided with an electric push rod two, and the output end of the electric push rod two being fixedly connected to a clamping plate.

[0008] Preferably, a U-shaped rod is fixedly connected to the bottom of the circular plate, and an outer ring is fixedly connected to one end of the U-shaped rod. A groove is provided on the outer wall of the column. A limit rod is fixedly connected to the outer wall of the U-shaped rod, and one end of the limit rod is slidably connected inside the groove. By setting the U-shaped rod, the outer ring can be moved upward when the circular plate moves upward. By setting the groove and the limit rod, the stability of the circular plate moving up and down can be improved.

[0009] Preferably, a motor is fixedly installed on the top of the support plate, and a second gear is fixedly connected to the top of the output shaft of the motor. A first gear is fixedly sleeved on the outer wall of the column, and the first gear and the second gear are meshed together. The motor is provided to drive the second gear.

[0010] Preferably, two brackets are fixedly connected to the top of the base plate, and the left side of the support plate is rotatably connected between the two brackets via a pivot. An electric push rod three is fixedly installed on the top of the base plate, and a universal joint is hinged to the output end of the electric push rod three. A hinge rod is hinged to the top of the universal joint, and the top of the hinge rod is hinged to the bottom of the support plate. A spring is provided at the bottom of the support plate, and the two ends of the spring are fixedly connected to the bottom of the support plate and the top of the base plate, respectively. The spring is provided to improve the stability of the support plate after rotation, so that it can be stably maintained in the position after rotation.

[0011] Preferably, the outer ring is provided with a lifting mechanism, which includes an L-shaped plate, an electric push rod four, and an inner ring. The L-shaped plate is fixedly connected to the bottom of the outer ring, the electric push rod four is fixedly installed inside the L-shaped plate, the inner ring is fixedly connected to the output end of the electric push rod four and is located between the outer ring and the plate, and the electric push rod two is fixedly installed at the top of the inner ring.

[0012] Preferably, a limiting groove is provided at the top of the outer ring, and a connecting block is fixedly connected to the outer wall of the inner ring, with the connecting block inserted into the inside of the limiting groove. The connecting block and the limiting groove are provided to limit the downward movement of the inner ring, so that when the inner ring moves to the lowest position, it is embedded between the circular plate and the outer ring.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. The adjustable clamping fixture for processing wooden chairs allows the wooden chair parts to be placed on top of a circular plate. Activating the second electric push rod can position the parts by moving the clamping plate, preventing misalignment during processing. Starting the motor can drive the column to rotate via gears one and two, thereby rotating the parts to adjust their processing position. Activating the first electric push rod can move the parts on top of the circular plate upwards, adjusting the processing height. Activating the third electric push rod can cause the support plate to rotate around the axis within a certain range, thereby adjusting the processing angle of the parts. This device allows for flexible adjustment of the processed wooden chair parts, improving processing efficiency.

[0015] 2. The adjustable clamping fixture for processing the wooden chair fixes the wooden chair parts between two clamping plates. Activating the electric push rod four moves the inner ring upwards, which in turn moves the parts upwards, suspending them in mid-air for better positioning. This adapts to different processing conditions and improves the practicality of the device. Attached Figure Description
