Description

Technical Field

[0001] This invention relates to the field of woodworking table production and processing technology for wooden machine tools, and in particular to a surface treatment device for wooden machine tool workbenches. Background Technology

[0002] The existing surface treatment procedures for wooden workbenches on machine tools not only occupy the operator's hands and reduce the overall efficiency of surface treatment, but also pose a safety hazard to the surrounding environment because the hot melting of wax blocks is done with an open flame, which may cause burns to the operator. Summary of the Invention

[0003] The purpose of this invention is to address the following shortcomings in the prior art: the operation steps not only occupy the operator's hands and reduce the efficiency of the entire surface treatment, but also, since the wax block is melted by an open flame, it may cause burns to the operator and pose a safety hazard to the surrounding environment. Therefore, this invention proposes a surface treatment device for wooden workbenches of machine tools.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A surface treatment apparatus for a wooden worktable of a machine tool, comprising: The mounting column has a mounting groove at its bottom, and the mounting groove is cylindrical. A fixing component is installed on the top of the mounting groove to fix the wax block. The fixing component includes a limiting plate, a fixing block and a threaded nail. One side of the limiting plate is connected to the top of the mounting groove through an elastic component, and the other side is fixedly connected to the fixing block. The threaded nail is fixedly connected to the center of the fixing block with its tip pointing downward. A grip assembly is symmetrically arranged on both sides of the mounting column for pressing down and fixing the assembly. The grip assembly includes a side plate, an elastic rod, a support spring tube, and a fixing rod. The bottom of the side plate is rotatably connected to the mounting column via a pivot. Two arc-shaped sliding openings are symmetrically opened on both sides of the mounting column. The arc-shaped sliding openings are deflected downwards and their inner ends communicate with the mounting groove. One end of the elastic rod is fixedly connected to the inner side of the side plate, and the rod body is slidably arranged inside the arc-shaped sliding opening. Two fixing rods are vertically fixedly connected to the limiting plate and fixedly connected to the bottom end of the elastic rod. Two support spring tubes are symmetrically fixedly connected to both sides of the mounting column, and their other ends are fixedly connected to the inner side of the side plate.

[0005] Preferably, a heating assembly is installed at the bottom of the mounting groove. The heating assembly includes a heating ring and a limiting ring. Multiple heating rings are fixedly installed at the bottom of the mounting groove. The limiting ring is fixedly connected inside the mounting groove and located above the heating rings. The inner diameter of the limiting ring is smaller than the diameter of the mounting groove.

[0006] Preferably, the elastic component includes a top tube and a spring. The top tube is fixedly connected to the top of the mounting groove, and the spring is located inside the top tube, with one end fixedly connected to the center of the top of the mounting groove and the other end fixedly connected to the center of the limiting plate.

[0007] Preferably, the top of the mounting column is provided with a threaded annular groove, and a limiting cover ring is threadedly connected inside the threaded annular groove. The limiting cover ring is threaded on the outside and has multiple limiting hooks fixedly connected in an annular shape on its bottom side. The limiting hooks are offset upwards towards the center of the limiting cover ring.

[0008] Preferably, a hydraulic locking assembly is fixedly installed on the side of the mounting post. The hydraulic locking assembly includes a hydraulic tube, a sniper, a first piston, and a second piston. The two hydraulic tubes are symmetrically opened inside both sides of the mounting post, with one end opening directly below the arc-shaped sliding port and the other end opening on the inner wall of the limiting ring. One end of the first piston is sealed and slidably disposed inside the upper opening of the hydraulic tube, and the other end is fixedly connected to the inner side of the side plate. The second piston is fixedly connected to the flat end of the sniper and is sealed and slidably disposed at the end of the hydraulic tube located on the inner wall of the limiting ring.

[0009] Preferably, the liquid tube has multiple ports at one end located on the inner wall of the limiting ring, and all ports are inclined downwards. Multiple spur seals are slidably disposed inside the ports and move inclined downwards.

[0010] Preferably, the diameter of the limiting plate is larger than the diameter of the inner ring of the limiting ring, the diameter of the fixing block is smaller than the diameter of the inner ring of the limiting ring, and a scraper ring is fixedly connected to the bottom edge of the fixing block, and the scraper ring is in close contact with the inner wall of the limiting ring during movement.

[0011] Preferably, the tip of the sniper is conical and the length is 2cm-3cm, and the multiple snipers are positioned inside the multiple liquid pipe ports.

[0012] Preferably, the liquid pipe is filled with coolant to cool down the wax block in the limiting ring section.

[0013] Compared with the prior art, the beneficial effects of the present invention are: When performing surface treatment on a wooden workbench of a machine tool, a wax block is inserted into the mounting groove, and its end is connected to a threaded pin by rotation to fix the wax block. During the processing, as the wax block decreases, pressing the side plates on both sides causes the moving side plates to move the elastic rod inside the arc-shaped sliding mouth, and the bottom end moves down the limiting plate. The wax block fixed on the fixing block moves down under the action of the limiting plate, thus ensuring that the wax block is coated on the contact surface with the wooden workbench of the machine tool. During the processing, the movement trajectory of the operator's hand must be perpendicular to the connection line between the two side plates to avoid changes in the force on the side plates due to movement, and to prevent the internal wax block from being subjected to unstable forces. This invention has a simple structure, can be operated with one hand, and can move the position of the wax block after it melts, thus ensuring the melting efficiency of the wax block. At the same time, the application method reduces the difficulty of subsequent application, freeing up the other hand to apply the wax, thereby improving the efficiency of surface treatment. When installing the wax block, the wax block is installed into the mounting groove by separating the limiting cover ring from the bottom of the mounting post by thread. The bottom of the wax block is limited by the limiting cover ring and the limiting hook 10, so that when the hand grip component squeezes the wax block, the bottom of the wax block has sufficient support. At the same time, the upwardly tilted limiting hook ensures that the middle of the wax block is in contact with the surface of the machine tool's wooden worktable. When the bottom of the wax block rubs against the surface of the wooden worktable of the machine tool, the wax block may rotate. Due to the threaded connection between the wax block and the screw, when the wax block and the screw rotate relative to each other again, due to the characteristics of the wax block, the contact point between the wax block and the screw cannot be effectively connected, which affects the movement of the wax block. The downward tilting jack can prevent the wax block from rotating, but does not affect the up and down movement of the wax block, and plays a role in steering and fixing the wax block. Because the wax block inside the limiting ring melts when heated, some of the wax will adhere to the inner wall of the limiting ring, resulting in wax waste and potential blockage. During the movement of the fixing block, the wax adhering to the inner wall of the limiting ring is scraped off by the scraping ring to avoid wax waste. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Reference Figure 1-4 A surface treatment apparatus for a wooden workbench of a machine tool, comprising: Mounting column 1, with a mounting groove 2 at the bottom of mounting column 1, the mounting groove 2 being a cylindrical groove; Fixing component 3 is installed on the top of the mounting groove 2 to fix the wax block. Fixing component 3 includes a limiting plate 31, a fixing block 32 and a threaded nail 33. One side of the limiting plate 31 is connected to the top of the mounting groove 2 through an elastic component 5, and the other side is fixedly connected to the fixing block 32. The threaded nail 33 is fixedly connected to the center of the fixing block 32 with its tip pointing downward. Hand grip assembly 4 is symmetrically arranged on both sides of the mounting column 1 and is used to press down the fixing assembly 3. The hand grip assembly 4 includes a side plate 41, an elastic rod 42, a support spring tube 43, and a fixing rod 44. The bottom of the side plate 41 is rotatably connected to the mounting column 1 through a pivot. The side plates 41 on both sides are used for the operator's hand grip. At the same time, during the processing, the movement trajectory of the operator's hand needs to be perpendicular to the connection line between the two side plates 41, so as to avoid the change of the force on the side plate 41 due to movement and to avoid the internal wax block being subjected to unstable force. Two arc-shaped sliding mouths are symmetrically opened on both sides of the mounting column 1. The arc-shaped sliding mouths are curved downward and the inner end is connected to the mounting groove 2. One end of the elastic rod 42 is fixedly connected to the inner side of the side plate 41, and the rod body is slidably arranged inside the arc-shaped sliding mouth. Two fixing rods 44 are vertically fixedly connected to the limiting plate 31 and fixedly connected to the bottom end of the elastic rod 42. Two support spring tubes 43 are symmetrically fixedly connected to both sides of the mounting column 1, and the other end is fixedly connected to the inner side of the side plate 41.

[0018] In this invention, when performing surface treatment on a wooden workbench of a machine tool, a wax block is inserted into the mounting groove 2, and its end is connected to a threaded pin 33 by rotation to fix the wax block. During the processing, as the wax block decreases, pressing the side plates 41 on both sides causes the moving side plates 41 to move the elastic rod 42 inside the arc-shaped sliding opening, and the bottom end moves down the limiting plate 31. The wax block fixed on the fixing block 32 moves down under the action of the limiting plate 31, thus ensuring that the wax block is coated on the contact surface with the wooden workbench of the machine tool. This invention has a simple structure, can be operated with one hand, and can move the position of the wax block after it melts, thus ensuring the melting efficiency of the wax block. At the same time, the application method reduces the difficulty of subsequent application, freeing up the other hand to apply the wax, thereby improving the efficiency of surface treatment.

[0019] In this preferred embodiment, a heating component 6 is installed at the bottom of the mounting groove 2. The heating component 6 includes a heating ring 61 and a limiting ring 62. Multiple heating rings 61 are fixedly installed at the bottom of the mounting groove 2, and the limiting ring 62 is fixedly connected inside the mounting groove 2 and located above the heating rings 61. The inner diameter of the limiting ring 62 is smaller than the diameter of the mounting groove 2. The heating rings 61 are located on the side of the mounting groove 2 and do not contact the wax block. The heating rings 61 raise the temperature of the end of the wax block, causing the wax block to melt. At the same time, the limiting ring 62 plays a certain role in blocking the heat conduction of the heating rings 61, preventing the wax block from melting as a whole and thus preventing the wax block from being effectively fixed. At the same time, it can ensure the melting effect of the end of the wax block. The elastic component 5 includes a top tube 51 and a spring 52. The top tube 51 is fixedly connected to the top of the mounting groove 2. The spring 52 is located inside the top tube 51, with one end fixedly connected to the center of the top of the mounting groove 2 and the other end fixedly connected to the center of the limiting plate 31. When the wax block is fixed, the top tube 51 presses against the limiting plate 31, allowing the wax block to rotate inside the machine thread 33. When the hand-held component 4 changes the position of the limiting plate 31, the spring 52 can ensure the tension and fixing effect of the limiting plate 31. When the limiting plate 31 is not subjected to external force, the spring 52 moves the limiting plate 31 to the top. The top of the mounting column 1 is provided with a threaded annular groove 8. The threaded annular groove 8 is connected to a limiting cover ring 9. The limiting cover ring 9 is threaded on the outside and has multiple limiting hooks 10 fixedly connected to the bottom in an annular shape. The limiting hooks 10 are offset upward towards the center of the limiting cover ring 9. When the wax block is installed, the limiting cover ring 9 is separated from the bottom of the mounting column 1 by threads, and the wax block is installed into the mounting groove 2. The bottom of the wax block is limited by the limiting cover ring 9 and the limiting hooks 10, so that when the hand grip component 4 squeezes the wax block, the bottom of the wax block has sufficient support. At the same time, the upwardly tilted limiting hooks 10 ensure that the middle of the wax block is in contact with the surface of the wooden worktable of the machine tool. A hydraulic locking assembly 7 is fixedly installed on the side of the mounting post 1. The hydraulic locking assembly 7 includes a liquid pipe 71, a sniper 72, a first piston 73, and a second piston 74. The two liquid pipes 71 are symmetrically opened inside both sides of the mounting post 1, with one end opening directly below the arc-shaped sliding opening and the other end opening on the inner wall of the limiting ring 62. One end of the first piston 73 is sealed and slidably disposed inside the upper opening of the liquid pipe 71, and the other end is fixedly connected to the inner side of the side plate 41. The second piston 74 is fixedly connected to the flat end of the sniper 72 and is sealed and slidably disposed at the end of the liquid pipe 71 located on the inner wall of the limiting ring 62. When the hand grip assembly 4 moves inward, the side plate 41 drives the first piston 73 to move inside the liquid pipe 71, squeezing the liquid inside the liquid pipe 71, thereby causing the second piston 74 to drive the sniper 72 to move outward from the liquid pipe 71, thereby positioning and limiting the wax block located inside the limiting ring 62. The liquid tube 71 has multiple ports at one end of the inner wall of the limiting ring 62, and all ports are inclined downward. Multiple slugs 72 are slidably disposed inside the ports and move downward. When the bottom of the wax block rubs against the surface of the wooden worktable of the machine tool, the wax block may rotate. Since the wax block is threadedly connected to the threaded nail 33, when the wax block and the threaded nail 33 rotate relative to each other again, due to the characteristics of the wax block, the contact point between the wax block and the threaded nail 33 cannot be effectively connected, which affects the movement of the wax block. The downward-sloping slugs 72 can prevent the wax block from rotating, but do not affect the up and down movement of the wax block, and play a role in turning and fixing the wax block. The diameter of the limiting plate 31 is larger than the inner ring diameter of the limiting ring 62, and the diameter of the fixing block 32 is smaller than the inner ring diameter of the limiting ring 62. A scraper ring 11 is fixedly connected to the bottom edge of the fixing block 32. The scraper ring 11 is in close contact with the inner wall of the limiting ring 62 during movement. In order to ensure that the wax block can be completely used up, the fixing block 32 needs to pass through the limiting plate 31 to move the wax block connected to the threaded nail 33 into the heating environment of the heating ring 61, so as to avoid wasting the wax block. Since the wax block inside the limiting ring 62 will melt when heated, some wax will adhere to the inner wall of the limiting ring 62, causing wax waste and potentially clogging the limiting ring 62. During the movement of the fixing block 32, the scraper ring 11 scrapes off the wax adhering to the inner wall of the limiting ring 62, thus avoiding wax waste. The tip of the stab 72 is conical and its length is 2cm-3cm. Multiple stabs 72 are set inside multiple liquid tube 71 ports. In order to avoid the wax block being unable to move down properly due to the stabs 72 penetrating too deeply, the length of the stabs 72 needs to be limited. The liquid pipe 71 is filled with coolant to cool down the wax block in the limiting ring 62. Due to the heat transfer of the pull block, in order to prevent the wax block from melting as a whole, the liquid pipe 71 is filled with coolant. While acting as a conductive fluid, it can also absorb heat from the wax block inside the limiting ring 62, ensuring the solid state of the upper part of the wax block and ensuring the effective displacement of the wax block by the fixing component 3.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
