Abstract
Description
Technical Field
[0001] This application relates to the field of planer technology, and in particular to a quick locking mechanism for a planer. Background Technology
[0002] In the wood processing industry, the planer is an important piece of machinery widely used for planing, trimming and thickness determination of wood. The planer adjusts the thickness of the wood being processed by lifting the worktable, and the stability of the lifting worktable and the reliability of the locking mechanism directly affect the processing accuracy and safety.
[0003] The lifting table of the planer is raised and lowered by the rotation of the screw. Positioning is achieved solely by the screw. When the machine is planing normally, the reaction force generated by planing will lift the machine body upward. The gap between the screw and the lead screw will affect the planing accuracy, making the accuracy uncontrollable and affecting product quality.
[0004] In the prior art, the applicant has proposed a quick locking mechanism for a planer (publication number CN219152225U) to solve the above problems and achieve the following: the starting method is simple, and after starting, the locking tube clamp can be squeezed by the deviation between the first cam seat and the second cam seat to lock the position of the machine head assembly, preventing the product accuracy from being affected by vibration. It also has low manufacturing cost, simple structure, and convenient installation.
[0005] The purpose of this application is to further improve the locking effect based on existing technology.
[0006] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention
[0007] Based on this, this application provides a quick locking mechanism for a planer to solve one of the above-mentioned technical problems.
[0008] The technical solution adopted by this application to solve its technical problem is: a quick-locking mechanism for a planer, including a planer body and a lifting worktable. Guide rods and lead screws are vertically arranged on both sides of the planer body. The lifting worktable is threaded onto the lead screws on both sides and can be raised and lowered on the guide rods by the rotation of the lead screws. A quick-locking mechanism is fixed on the lifting worktable for locking the lifting worktable, including: a connecting shaft with an eccentric handle rotatably at one end, and an annular first convex tooth formed on the eccentric handle; A clamping seat slides on the guide rod, one end of which is fixed to the lifting worktable and is penetrated by the connecting shaft; an intermediate driving member is sleeved on the connecting shaft and keeps in contact with the clamping seat, and a second protruding tooth is formed on it that meshes with the first protruding tooth; a locking block is fixed on the connecting shaft and contacts the lead screw; by pressing down on the eccentric handle, the eccentricity of the eccentric handle increases, causing the connecting shaft to shift in the direction of the handle, thereby deforming the intermediate driving member, causing the clamping seat to press the guide rod, and at the same time, the locking block will also press the lead screw.
[0009] In some embodiments, a receiving groove is formed on the clamping seat, and the intermediate drive member is placed in the receiving groove.
[0010] In some embodiments, a pair of guide rods and a lead screw are symmetrically arranged on both sides of the planer body, and the clamping seats are arranged in pairs and slide on the two guide rods respectively.
[0011] In some embodiments, the two clamping seats are respectively sleeved on both ends of the connecting shaft, and the eccentric handle and its cooperating components are disposed on at least one of the clamping seats.
[0012] In some embodiments, the locking block has a receiving hole, the lead screw is placed in the receiving hole, and a thread is formed in the receiving hole to engage with the lead screw.
[0013] In some embodiments, pressing the eccentric handle downwards locks the quick-locking mechanism; raising the eccentric handle unlocks the quick-locking mechanism.
[0014] In some embodiments, the quick-locking mechanism is provided at least on one side of the lifting platform.
[0015] The advantages of this application are: convenient operation and simple structure. Simply turn the eccentric handle downwards, and under the guidance of the second convex tooth on the intermediate drive component, drive the connecting shaft to deflect, thereby causing the intermediate drive component to deform. This will drive the pressing seat and locking component to press the guide rod and lead screw respectively to achieve double locking and complete the rapid locking of the lifting worktable.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.
[0024] In the embodiments of this application, please refer to Figure 1-5As shown, the quick-locking mechanism of a planer mainly includes: a planer body 1 and a lifting worktable 2. Guide rods 3 and lead screws 4 are vertically arranged on both sides of the planer body 1. The lifting worktable 2 is threaded onto the lead screws 4 on both sides and can be raised and lowered on the guide rods 3 by rotating the lead screws 4. A quick-locking mechanism 5 is fixed on the lifting worktable 2 for locking the lifting worktable 2. It includes: a connecting shaft 501 with an eccentric handle 502 rotating at one end, the eccentric handle 502 having an annular first convex tooth; and a clamping seat 503 sliding on the guide rods 3. The end is fixed on the lifting worktable 2 and is penetrated by the connecting shaft 501; the intermediate drive member 504 is sleeved on the connecting shaft 501 and keeps in contact with the pressing seat 503, and a second convex tooth is formed on it to mesh with the first convex tooth; the locking block 505 is fixed on the connecting shaft 501 and contacts the lead screw 4; by pressing down the eccentric handle 502, the eccentricity of the eccentric handle 502 increases, causing the connecting shaft 501 to shift in the direction of the handle, thereby deforming the intermediate drive member 504, causing the pressing seat 503 to press the guide rod 3, and at the same time, the locking block 505 will also press the lead screw 4.
[0025] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.
[0026] like Figure 5 As shown, a receiving groove 6 is formed on the clamping seat 503, and the intermediate driving member 504 is placed in the receiving groove 6. After the eccentric handle 502 is pressed down, the connecting shaft 501 deflects downward. The squeezing and deformation of the intermediate driving member 504 causes the clamping seat 503 to tilt and shift to one side of the eccentric handle 502, increasing the friction between it and the guide rod 3 to achieve rapid locking.
[0027] Specifically, the planer body 1 has a pair of guide rods 3 and a lead screw 4 symmetrically arranged on both sides. The clamping seats 503 are arranged in pairs and slide on the two guide rods 3 respectively. The lifting worktable 2 moves up and down by rotating the lead screw 4. The guide rods 3 provide limit guidance for the lifting worktable 2, and the clamping seats 503 are used to clamp the guide rods 3 when quickly locking.
[0028] like Figure 3 As shown, the two clamping seats 503 are respectively sleeved on both ends of the connecting shaft 501. The eccentric handle 502 and its cooperating components are at least set on one of the clamping seats 503. That is, after the quick locking mechanism 5 is locked, at least one of the two guide rails on one side of the planer body 1 is pressed by the clamping seat 503.
[0029] Furthermore, the locking block 505 has a receiving hole 7, and the lead screw 4 is placed in the receiving hole 7. A thread is formed in the receiving hole 7 that meshes with the lead screw 4. When the lifting worktable 2 is raised and lowered, the locking block 505 moves in conjunction with the lead screw 4. When the quick locking mechanism 5 locks, the connecting shaft 501 shifts and drives the locking block 505 to press the lead screw 4 together with the pressing seat 503 to achieve two types of pressing and increase the pressing effect.
[0030] Specifically, when the eccentric handle 502 is pressed down, the rotation points of the eccentric handle 502 and the connecting shaft 501 move downward, causing the connecting shaft 501 to shift downward, ultimately driving the pressing seat 503 and the locking block 505 to press together, thus locking the quick-locking mechanism 5; when the eccentric handle 502 is raised upward, the eccentric handle 502 drives the connecting shaft 501 back to horizontal, and the pressing seat 503 and the locking block 505 contact the guide rod 3 and the lead screw 4 but do not press together, thus unlocking the quick-locking mechanism 5.
[0031] Furthermore, the quick-locking mechanism 5 is at least disposed on one side of the lifting worktable 2. Various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
