Description

Technical Field

[0001] The utility model belongs to the technical field of wood board processing equipment, in particular to a positioning fixture for a wood board planer. Background Art

[0002] The planer is mainly used to process flat wood. It is a woodworking machine tool whose structure mainly includes a bed, a workbench, a driving motor, a clamping device, a sliding device, etc. The working principle of the planer is to drive the sliding device on the workbench through the driving motor, so that the wood can be cut under the action of the clamping device.

[0003] The Chinese patent discloses a multifunctional positioning fixture for a planer (CN217861765U), which relates to the technical field of planers, and includes a planer body, a connecting base is fixedly installed on the side of the planer body, a support frame is fixedly installed on the top of the connecting base, positioning components are movably installed at both ends of the support frame, and an auxiliary support device is movably installed inside the connecting base. In the above scheme, when the planer needs to process the wooden board, the wooden board is placed at the bottom of the connecting cover, and the wooden board pushes the push plate to the side, and the push plate positions the wooden board to prevent the wooden board from being tilted, and to prevent the wooden board from hitting the planer and causing material jamming during processing, and to avoid damage to the wooden board. By turning the locking bolt and pulling the pull handle, the sliding plate is moved out of the base cover, and the longer wooden board is placed on the top of the supporting roller, so as to reduce the vibration amplitude of the wooden board during the planing process, make the surface planing pin more flat, improve the planing effect of the wooden board, and improve the processing quality of the wooden board. At present, the clamp used by the planer machine lacks a lubrication component between the wooden board and the clamp during the positioning and clamping of the wooden board. On the one hand, it is not convenient to push the wooden board, and on the other hand, it will cause wear to the clamp, reducing the service life of the mold, and in the process of planing the wooden board, most of the wooden boards are pressed manually, which is dangerous. Therefore, a positioning clamp for a wooden board planer is provided. Utility Model Content

[0004] The utility model aims to solve the problem that the current clamp has poor sliding effect when clamping a wooden board, and proposes a positioning clamp for a wooden board planer.

[0012] The mounting assembly comprises a fixing plate and a supporting plate. The upper surface of the fixing plate is provided with a sliding groove, and the bottom inner wall of the sliding groove is slidably connected to the lower surface of the supporting column.

[0013] As a further description of the above technical solution:

[0014] A connecting spring is fixedly installed on the inner side wall of the slide slot, and one end of the connecting spring is fixedly connected to the side wall of the support column.

[0015] As a further description of the above technical solution:

[0016] A self-locking threaded rod is threadedly installed on the inner wall of the fixing plate, one end of the self-locking threaded rod extends to the upper surface of the fixing plate, a turning handle is fixedly installed on one end of the self-locking threaded rod, and the other end of the self-locking threaded rod extends to the outside of the lower surface of the fixing plate, a fixing sleeve is fixedly installed on the upper surface of the support plate, and the other end of the self-locking threaded rod is rotatably connected to the inner wall of the fixing sleeve.

At this time, the threaded sleeve drives the positioning plate to make relative movement under the action of the thread, and the distance between the two positioning plates is adjusted according to the size of the wooden board. Then, according to the thickness of the wooden board, the pressing plate will press the wooden board on the table of the planer under the action of the telescopic spring. When the planer is working, the wooden board is pushed. At this time, the pressing plate and the positioning plate are in contact with the wooden board through the ball bearings, which reduces the friction between the wooden board and the pressing plate and the positioning plate, thereby reducing the wear of the pressing plate and the positioning plate, and prolonging the service life of the clamp. At the same time, it is convenient to push the wooden board, and the pressing function is automatically realized on the wooden board while positioning the wooden board, thereby reducing the jitter of the wooden board during the planing process, and improving the planing effect of the wooden board. The positioning plate can be adjusted according to the size of the wooden board, which reduces the limitations of the planing board.

[0019] 2. In the utility model, a mounting assembly is provided to fit the upper surface of the support plate with the lower surface of the table on one side of the planer, and then the self-locking threaded rod is rotated by turning the handle. As the self-locking threaded rod rotates, the fixed plate moves downward under the action of the thread, thereby clamping the table of the planer through the fixed plate and the support plate, and the self-locking threaded rod is fixed under the action of the fixed sleeve, thereby fixing the shell through the support column, and then the fixed plate at the other end of the shell is pulled to one side, so that the table on the other side of the planer is between the fixed plate and the support plate, and then the fixed plate and the support plate are clamped to the table in the same way, so that the clamp is fixed on the planer. Since the mounting assembly can be moved on the clamp, the clamp can be suitable for planers of different sizes, thereby improving the scope of use of the clamp and thus improving the practicality of the clamp.
