Currently, many cylindrical wooden products require drilling holes in their curved surfaces. Drilling usually requires a drilling machine, but fixing cylindrical wooden products is extremely inconvenient. Without specialized clamps, the yield rate is low. Furthermore, existing clamps for cylindrical wooden products are rigid clamps, making it difficult to control the clamping force, which can easily damage the surface of the cylindrical wooden products. Work efficiency also needs further improvement.

[0003] Existing technology CN213080797U discloses a cylindrical wooden product arc surface drilling fixture, relating to the field of wood product processing technology. It includes a base, a baffle, a first clamping plate, and a telescopic cylinder, fixedly mounted on the base from left to right. A spring plate is fixedly mounted on the baffle, and a sleeve and a support column are fixedly mounted on the clamping plate. A connecting cylinder is movably mounted between the sleeve and the support column, and the connecting cylinder is fixedly connected to the spring plate. A second clamping plate is fixedly mounted at the end of the telescopic cylinder. This utility model fixture has a simple structure, reasonable design, is practical and convenient, and easy to operate. It changes the existing rigid clamping method of fixtures, effectively overcoming the drawbacks of damage or breakage when cylindrical wooden products are clamped by front and rear end compression fixing, which is beneficial to improving product yield and work efficiency.

[0004] However, the aforementioned cylindrical wooden product arc surface drilling fixture cannot be used to clamp and fix cylindrical wooden products of different lengths for drilling, which is not conducive to the production and processing of wooden toys. Utility Model Content

The slide block 104 is bolted to the linear slider equipped on the linear guide rail 103. The drive screw 105 is rotatably connected to the base plate 101. The drive screw 105 is detachably connected to the slide block 104 and located on the side of the base plate 101 near the slide block 104. The servo motor 106 is fixedly connected to the base plate 101, and its output shaft is connected to the drive screw 105 and located on the right side of the base plate 101. The rotating device is located on the left side of the left positioning seat 102, and the right positioning device is located on the side of the slide block 104 near the left positioning seat 102. The positioning mandrel of the left positioning seat 102 can be directly and easily inserted and fixed to the left side of the cylindrical accessory of the wooden toy. The linear guide rail 103 is fixed to the base plate 101 by bolts and is symmetrically arranged. Its linear slider is connected to the slide 104 by bolts. The two sides of the drive screw 105 are respectively mounted in the detachable bearing seats on the base plate 101 by rotating bearings. The mating nut of the drive screw 105 is fixed in the mounting hole on the mounting protrusion at the lower end of the slide 104 by bolts. The servo motor 106 is equipped with a brake mechanism and an encoder for easy stopping, shaft locking and position control. It is mounted on the base plate 101 by bolts. Its output shaft is connected to the drive screw 105 by a rigid coupling. The rotating device is used to adjust the processing angle of the accessory. The right positioning device cooperates with the left positioning seat 102 to realize the workpiece fixing and clamping.

[0024] Secondly, the support plate 107 is fixedly connected to the base plate 101 and is located on the left side of the base plate 101; the servo turntable 108 is fixedly connected to the support plate 107, its output end is connected to the left positioning seat 102, and it is located on the support plate 107. The support plate 107 is installed on the base plate 101 by positioning pins and bolts, which are arranged from bottom to top and are countersunk. The servo turntable 108 is installed on the support plate 107 by positioning pins and bolts, and its output end rotary disk is connected to the left positioning seat 102 by positioning pins and bolts. The servo motor driving the servo turntable 108 is equipped with a brake mechanism and an encoder.

[0025] Then, the fixing plate 109 is fixedly connected to the slide 104 and is located on the slide 104; the limiting component is disposed between the fixing plate 109 and the left positioning seat 102. The fixing plate 109 is installed on the slide 104 by positioning pins and bolts, which are arranged from bottom to top and are countersunk. The limiting component is used for clamping.

The abutment plate 111 is mounted on the turntable 110 by bolts, with the bolts arranged from the rear to the front to facilitate abutment against the right end face of the cylindrical accessory.

[0027] When using this invention to clamp and fix cylindrical wooden products of different lengths for drilling, the fixture is first installed on the machining center workbench via the base plate 101. Then, one end of the cylindrical part of the wooden toy is inserted into the left positioning seat 102. Next, the servo motor 106 is controlled to rotate the drive screw 105, causing the slide 104 to move, which in turn moves the turntable 110 and the abutment plate 111. The abutment plate 111 abuts against the right side of the cylindrical part, clamping it. The part can then be processed through the machining center. The servo motor 106 drives the cutting tool to perform drilling. Under the position control of the encoder, the slide 104 can be stopped at different positions to clamp cylindrical parts of different lengths. After the servo turntable 108 is activated, it can drive the left positioning seat 102 to rotate. The turntable 110 rotates under the force, which allows the workpiece to be rotated at an adjustable angle before drilling. This solves the problem that existing wood product drilling fixtures cannot clamp and fix cylindrical wood products of different lengths for drilling, which is not conducive to the production and processing of wooden toys.
