Description

Technical Field

[0001] The utility model relates to the field of wood processing, in particular to a clamping device for drilling wood. Background Art

[0002] Wood processing is the processing of wood as raw material, mainly by mechanical or chemical methods, and its products still retain the basic characteristics of wood. In the forest industry, wood processing industry and forest product chemical processing are both follow-up industries of forest felling and transportation, and are important sectors for the comprehensive utilization of wood resources. Some of the wood after preliminary processing is processed into shorter cylinders, and the shorter cylinder wood can be processed into a variety of wooden products. In some wood processing, wood needs to be punched in order to lay wires in the wood or install screws, bolts and other connectors.

[0003] Existing wood drilling clamping devices usually consist of two end clamps and a top clamping mechanism. The top clamping mechanism usually uses a robotic arm clamping device or an auxiliary fixing mechanism. Compared with the auxiliary fixing mechanism, the robotic arm can reduce the shaking of the wood during drilling to a greater extent. However, the robotic arm needs to be adjusted multiple times when handling wood of different diameters, and then clamped by the robotic arm. In addition, the robotic arm is relatively expensive, which imposes an additional burden on small and medium-sized enterprises. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3A wood drilling clamping device comprises a base 1 and a plurality of brackets 4, and each bracket 4 is fixedly installed on the top surface of the base 1, and a double-headed screw 16 is rotatably connected in the base 1, and both ends of the double-headed screw 16 are located in the center of the side wall of the corresponding groove 15, and the groove 15 is connected to a storage box, so that the double-headed screw 16 and the bottom wall of the groove 15 are not in contact. When the wood is being drilled, the drilled waste will not accumulate on the double-headed screw 16, but will be connected to the storage box through the groove 15, and then fall into the storage box, which is convenient for subsequent cleaning. The double-headed screw 16 is symmetrically threaded with two clamps 3 , and then by starting the motor 2, the double-headed screw 16 is driven to rotate, and then the two clamps 3 clamp the wood. The motor 2 is fixedly installed on the side of the base 1, and the output shaft of the motor 2 passes through the base 1 and is connected to the double-headed screw 16. A groove 15 is provided in the base 1, and the groove 15 is square in shape, and the double-headed screw 16 is rotatably connected in the groove 15. A bottom plate 14 is fixedly installed on the outside of each clamp 3, and each bottom plate 14 and the clamp 3 are slidably connected in the groove 15. When the wood is initially placed, the bottom plate 14 is used to prevent the wood from directly contacting the double-headed screw 16;

[0020] An electric telescopic rod 5 is fixedly installed on the bottom surface of each bracket 4, a cylinder 6 is fixedly installed on the bottom surface of each electric telescopic rod 5, a slide plate 8 is slidably connected in each cylinder 6, a spring 7 is installed between the top surface of each slide plate 8 and the top wall of the cylinder 6, and the slide plate 8 is reset by the spring 7, an extension rod 9 is fixedly installed on the bottom surface of each slide plate 8, a tooth plate 11 is installed on both sides of each extension rod 9, a baffle 12 is symmetrically installed at the bottom end of each extension rod 9, and each baffle 12 corresponds to the position of the tooth plate 11, and the baffle 12 prevents the gear 13 from disengaging, and a clamp arm 10 is symmetrically rotated in each cylinder 6 A non-slip pad is installed on the inner side of each clamping arm 10, and the friction between the clamping arms 10 is increased and further fixed by the non-slip pad when the clamping arms 10 clamp the wood. A rotating shaft is rotatably connected inside each clamping arm 10, and each rotating shaft is fixedly installed in the cylinder 6. A gear 13 is installed on each clamping arm 10, and each gear 13 is meshed with a tooth plate 11 at a corresponding position. The cylinder 6 is driven downward by the electric telescopic rod 5, and then the extension rod 9 is against the wood, thereby pushing the extension rod 9 to retract inward, and then the tooth plate 11 is meshed with the gear 13, thereby driving the two clamping arms 10 to clamp the wood.

[0021] When the utility model is used, the staff first places the wood on the two bottom plates 14, and then starts the motor 2 to drive the double-headed screw 16 to rotate, and at the same time, each clamping plate 3 is threadedly connected with the double-headed screw 16, so that the two clamping plates 3 clamp and fix the wood, and at the same time, when the clamping plates 3 move, the bottom plates 14 are driven to move synchronously;

[0022] Then, when both ends of the wood are fixed, the cylinder 6 can be started, thereby driving the cylinder 6 to move downward. During the movement, the extension rod 9 contacts the wood first, and then the cylinder 6 continues to move, so that the extension rod 9 slides upward in the cylinder 6, and then the toothed plates 11 installed on both sides of the extension rod 9 engage with the gear 13, thereby driving the gear 13 to rotate, and then the two clamping arms 10 clamp and fix the wood. When the two clamping arms 10 are completely and tightly fitted with the wood, the height of the extension rod 9 is fixed at this time, and then the rotation angle of the two clamping arms 10 is fixed, so that the clamping arms 10 can be self-adapted, and there is no need to adjust the clamping jaws according to the height of each piece of wood.
