Description

Technical Field

[0001] This utility model relates to the field of wood product processing technology, and in particular to a clamping and fixing device for wood product carving. Background Technology

[0002] Wood products are mainly divided into the following categories: furniture wood products, office wood products, craft wood products, garden wood products, household wood products, and now high-tech wood products. Wood carving is just one branch of craft wood products. Wood carving is divided into two main categories: craft wood carving and artistic wood carving. Craft wood carving can be further divided into ornamental and practical types.

[0003] Currently, most wood carvings are machine-made. Before carving, the blank needs to be fixed. Therefore, this application discloses a clamping and fixing device for wood carving. Utility Model Content

[0004] The purpose of this invention is to address existing problems by providing a clamping and fixing device for carving wood products.

[0005] This utility model is achieved through the following technical solution: a clamping and fixing device for carving wood products, including a support frame, an operating table installed on the support frame, clamping plates symmetrically arranged on the operating table, a driving block arranged in the middle below the clamping plates, and guide blocks symmetrically arranged on both sides below the clamping plates. The driving block and the guide blocks both pass through the operating table. The lower end of the driving block is threaded onto a lead screw. One end of the lead screw is connected to the output shaft of a motor. The motor is installed on one end of the frame through a machine plate. The guide blocks are slidably fitted onto a guide rod. Both ends of the guide rod are connected to the frame. A pressing mechanism is symmetrically connected to both sides of the operating table.

[0006] As a further improvement to the above solution, the operating table is provided with a matrix of supporting balls for placing the slotted pads or directly placing the blanks, which facilitates the displacement of the blanks.

[0007] As a further improvement to the above solution, the pressing mechanism includes a support arm, which is symmetrically installed on the front and rear sides of the operating table. A sliding sleeve is connected through the support arm, and a support rod is installed inside the sliding sleeve. The lower end of the support rod is connected to an end plate, and the upper end of the support rod is connected to a rotating arm. A cylinder is vertically installed on the outer end of the rotating arm, and the end of the telescopic rod of the cylinder is connected to a pressure plate. A locking and limiting screw is connected through the support arm.

[0008] The billet is placed on the operating table or on the slotted pad. The pressure plate is pressed against the corner of the billet by rotating the support rod, and the billet is fixed by the cylinder.

[0009] As a further improvement to the above solution, the operating table is symmetrically laid with slotted pads in the middle; these are used to place the billets and to pull them apart or merge them by relative displacement of the slotted pads, so as to accommodate billets of different sizes.

[0010] As a further improvement to the above solution, the driving block and the guide block pass through the driving groove and the guide groove respectively. The driving groove and the guide groove are symmetrically and continuously arranged on the operating table. The driving groove is a channel for the displacement of the driving groove, and the guide groove is a channel for the displacement of the guide block.

[0011] As a further improvement to the above solution, the lead screw is provided with two sections of threads in opposite directions, and two drive blocks are threadedly fitted onto the two sections of threads. When the lead screw rotates, the two drive blocks move closer to each other or further away from each other.

[0012] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. It uses a motor to drive the lead screw to rotate and drive the drive block and clamping plate to clamp or release the blank. It also uses a pressing mechanism to press the blank as needed for positioning to facilitate carving. In addition, larger blanks can be placed on the slot pad, and the slot pad can be moved to increase the bearing area. The ball on the operating table can easily drag and rotate the slot pad or blank.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 As shown, a clamping and fixing device for carving wood products includes a support frame 1, an operating table 2 mounted on the support frame 1, clamping plates 3 symmetrically arranged on the operating table 2, a driving block 4 arranged in the middle below the clamping plates 3, and guide blocks 6 symmetrically arranged on both sides below the clamping plates 3. The driving block 4 and the guide blocks 6 both pass through the operating table 2. The lower end of the driving block 4 is threaded onto a lead screw 5. One end of the lead screw 5 is connected to the output shaft of a motor 8. The motor 8 is mounted on one end of the frame 1 through a machine plate. The guide blocks 6 are slidably mounted on a guide rod 7. Both ends of the guide rod 7 are connected to the frame 1. The two sides of the operating table 2 are symmetrically connected to pressing mechanisms 9.

[0018] As a further improvement to the above scheme, the operating table 2 is provided with a matrix of supporting balls 13; these balls are used to place the slotted pads 12 or directly place the blanks, facilitating the displacement of the blanks.

[0019] As a further improvement to the above solution, the pressing mechanism 9 includes a support arm 91, which is symmetrically installed on the front and rear sides of the operating table 2. A sliding sleeve 92 is sleeved through the support arm 91, and a support rod 93 is installed inside the sliding sleeve 92. The lower end of the support rod 93 is connected to an end plate 94, and the upper end of the support rod 93 is connected to a rotating arm 96. A cylinder 97 is vertically installed on the outer end of the rotating arm 96.
