Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, specifically to a hydrostatic precision CNC lathe. Background Technology

[0002] Hydrostatic precision CNC lathes are advanced machine tools that combine hydrostatic technology and precision CNC technology, providing strong support for high-precision and high-efficiency machining. Firstly, with the continuous development of modern industrial manufacturing technology, the requirements for the precision, surface quality, and shape of parts are becoming increasingly stringent. This is especially true in the automotive, aerospace, electronics, and medical fields, where the demand for high-precision parts is growing rapidly. Therefore, hydrostatic precision CNC lathes have emerged to meet the high-precision machining needs of these industries. Secondly, hydrostatic technology, as a mature lubrication and support technology, has advantages such as a low coefficient of friction, high rigidity, and good stability. Applying hydrostatic technology to CNC lathes can effectively improve the machining accuracy and stability of the machine tool, while reducing thermal deformation and vibration during machining, thereby further improving machining quality.

[0003] A search revealed a utility model patent with publication number CN118002811A, which specifically discloses a hydrostatic precision CNC lathe. The lathe includes a lathe housing, a machining base fixedly installed within the lathe housing, a translation guide rail fixedly installed on the machining base, a first moving platform slidably installed on the translation guide rail, and a second moving platform slidably installed on the first moving platform. The lathe also includes a support plate fixedly connected to both the lathe housing and the machining base; and a cleaning and adjustment mechanism connected to the lathe housing, the first moving platform, the support plate, and the tool holder. This cleaning and adjustment mechanism includes a control system, a detection component, and a blowing cleaning component. This hydrostatic precision CNC lathe can prevent waste chips generated during machining from falling onto the machining tools, thus avoiding workpiece damage. It also features a high degree of automation, providing convenience for workers.

[0004] Although the aforementioned patent describes a blower cleaning component that can collect waste generated during processing by blowing it into a waste box, the existing waste box is typically fixed inside the lathe with multiple bolts. This makes the disassembly and replacement process extremely cumbersome and time-consuming, posing a safety hazard to operators who spend long periods of time inside the lathe.

[0005] Therefore, it is necessary to propose a hydrostatic precision CNC lathe to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a hydrostatic precision CNC lathe. Through the cooperation of the internal parts of the limiting mechanism, the electric slide is fixed at the upper limit of the lathe body when the protective door is opened, preventing accidental operation of the electric slide. Through the cooperation of the internal parts of the fixing mechanism, the scrap box is automatically released from the electric slide when the protective door is opened, allowing the operator to directly disassemble and replace the scrap box. This solves the problem that in the prior art, the scrap box is generally fixed inside the lathe with multiple bolts, which makes the disassembly and replacement process extremely cumbersome and time-consuming, posing a certain safety hazard to the operator when working on the lathe for a long time.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a liquid hydrostatic precision CNC lathe, comprising a lathe body, a protective door slidably connected to the surface of the lathe body, a limit mechanism slidably connected to the inner wall of the lathe body and extending into the interior of the lathe body, and a fixing mechanism installed at the top of the limit mechanism and extending into the interior of the limit mechanism;

[0008] The limiting mechanism includes a connecting plate, which is slidably connected to the interior of the lathe body and fits against the surface of the protective door. The top of the lathe body is slidably connected to the limiting mechanism via an electric slide rail. A telescopic spring is mechanically connected between the connecting plate and the interior of the lathe body. A support seat is slidably connected to the top of the connecting plate and extends into the interior of the lathe body. A support spring is mechanically connected between the bottom of the support seat and the connecting plate, and the support seat and the outer wall of the support spring are nested together.

[0009] The fixing mechanism includes a waste box, which is installed on the top of the electric slide table. Multiple connecting strips are welded and fixed to the bottom of the waste box and extend into the interior of the electric slide table. A fixing column is slidably connected inside the electric slide table and is located on one side of the connecting strips. A return spring is mechanically connected between the fixing column and the interior of the electric slide table.

[0010] Preferably, the limiting mechanism further includes a limiting seat, which is slidably connected to the bottom end of the electric slide table and fits against the top end of the support seat. Connecting columns are mechanically fixed on both sides of the top end of the limiting seat and located at the bottom end of the fixed columns. A connecting spring is mechanically connected between the top end of the limiting seat and the bottom end of the electric slide table.

[0011] Preferably, the top of the electric slide table is provided with a docking groove that matches the docking bar, and the waste box is located below the processing tool and the workpiece to be processed, and the side of the docking bar is provided with a fixing groove that matches the fixing column.

[0012] Preferably, the surface of the connecting plate near the protective door is set as a tapered surface, and the lathe body has a sliding groove that matches the connecting plate inside, and a support groove that matches the support seat inside, and the contact surfaces of the two sides of the support groove with the top of the support seat are tapered surfaces.

[0013] Preferably, the bottom end of the electric slide table is provided with a contraction groove that matches the limiting seat, and the elastic coefficient of the support spring is greater than that of the connecting spring.

[0014] Preferably, the electric slide table has a support groove inside that matches the connecting column, and the contact surface between the top of the connecting column and the bottom of one side of the fixed column is set as a conical surface.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By cooperating with the electric slide rail and the electric slide table, the electric slide table slides to the far left inside the lathe body, opening the protective door to release the pressure on the connecting plate. The telescopic spring returns to its original position, pushing the connecting plate out from inside the lathe body. The movement of the connecting plate drives the top support seat to move, causing the support seat to press against the tapered surface on the side of the support groove. This forces the support seat to compress the support spring, which then moves from inside the support groove into the connecting plate, releasing the pressure on the limiting seat. The connecting spring returns to its original position, pushing the limiting seat to slide from the bottom of the electric slide table into the lathe body. This completes the limiting and fixing of the electric slide table inside the lathe body, preventing accidental activation of the electric slide table.

[0017] 2. By using the resetting spring to push the limit seat to slide from the bottom of the electric slide table into the lathe body, the movement of the limit seat causes the connecting columns on both sides of the top to move, causing the connecting columns to move downwards to release the pressure on the fixed column. Simultaneously, the fixed column releases the pressure on the reset spring, and the reset spring pushes the fixed column to slide inside the electric slide table, causing the fixed column to slide out from the inner wall of the docking strip. This releases the connection between the docking strip and the electric slide table, allowing the worker to directly remove the waste box from the top of the electric slide table, thus completing the disassembly and replacement of the waste box and reducing the time required for disassembly and replacement.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1-4 The liquid hydrostatic precision CNC lathe shown includes a lathe body 1, a protective door 101 slidably connected to the surface of the lathe body 1, a limit mechanism 2 slidably connected to the inner wall of the lathe body 1 and extending into the interior of the lathe body 1, and a fixing mechanism 3 installed at the top of the limit mechanism 2 and extending into the interior of the limit mechanism 2.

[0027] The limiting mechanism 2 includes a connecting plate 201, which is slidably connected to the inside of the lathe body 1 and fits against the surface of the protective door 101. The top of the lathe body 1 is slidably connected to the limiting mechanism 2 via an electric slide rail. A telescopic spring 203 is mechanically connected between the connecting plate 201 and the inside of the lathe body 1. A support seat 204 is slidably connected to the top of the connecting plate 201 and extends into the inside of the lathe body 1. A support spring 205 is mechanically connected between the bottom of the support seat 204 and the connecting plate 201, and the support seat 204 and the outer wall of the support spring 205 are nested together.

[0028] The fixing mechanism 3 includes a waste box 301, which is installed on the top of the electric slide table 202. Multiple connecting strips 302 are welded and fixed to the bottom of the waste box 301 and extend into the interior of the electric slide table 202. A fixing column 303 is slidably connected inside the electric slide table 202 and is located on one side of the connecting strips 302. A return spring 304 is mechanically connected between the fixing column 303 and the interior of the electric slide table 202.

[0029] By cooperating with each other among the internal parts of the limiting mechanism 2, the electric slide 202 is fixed at the upper limit of the lathe body 1 when the protective door 101 is opened, preventing accidental operation of the electric slide 202. By cooperating with each other among the internal parts of the fixing mechanism 3, the installation and fixing of the waste box 301 on the electric slide 202 is automatically released when the protective door 101 is opened, making it convenient for workers to directly disassemble and replace the waste box 301.

[0030] Refer to the instruction manual appendix Figures 1-4 The limiting mechanism 2 also includes a limiting seat 206, which is slidably connected to the bottom end of the electric slide table 202 and fits against the top end of the support seat 204. Connecting columns 207 are mechanically fixed on both sides of the top end of the limiting seat 206 and are located at the bottom end of the fixing column 303. A connecting spring 208 is mechanically connected between the top end of the limiting seat 206 and the bottom end of the electric slide table 202. Through the mutual cooperation between the internal parts of the limiting mechanism 2, the limiting seat 206 can slide into the lathe body 1 to complete the limiting and fixing between the electric slide table 202 and the lathe body 1.

[0031] Refer to the instruction manual appendix Figures 1-4 The top of the electric slide table 202 is provided with a docking groove that matches the docking bar 302, and the waste box 301 is located below the processing tool and the workpiece to be processed. The side of the docking bar 302 is provided with a fixing groove that matches the fixing post 303. The docking groove on the top of the electric slide table 202 matches the docking bar 302, and the fixing groove on the side of the docking bar 302 matches the fixing post 303, so that the waste box 301 can be docked and connected to the top of the electric slide table 202 through the docking bar 302.

[0032] Refer to the instruction manual appendix Figures 1-4 The surface of the connecting plate 201 near the protective door 101 is set as a conical surface, and the lathe body 1 has a sliding groove that matches the connecting plate 201 inside. The lathe body 1 also has a support groove that matches the support seat 204 inside. The two sides of the support groove and the top of the support seat 204 are conical surfaces. The fact that the lathe body 1 has a support groove that matches the support seat 204 inside and the two sides of the support groove and the top of the support seat 204 are conical surfaces makes it easy for the connecting plate 201 to slide and drive the support seat 204 to slide within the support groove.

[0033] Refer to the instruction manual appendix Figures 1-4The bottom end of the electric slide table 202 is provided with a retraction groove that matches the limit seat 206, and the elastic coefficient of the support spring 205 is greater than that of the connecting spring 208. The retraction groove at the bottom end of the electric slide table 202 that matches the limit seat 206 and the elastic coefficient of the support spring 205 are greater than that of the connecting spring 208 make it easy for the support seat 204 to slide and contact the limit seat 206, pushing the limit seat 206 to retract into the interior of the lathe body 1 and into the electric slide table 202.

[0034] Refer to the instruction manual appendix Figures 1-4 The electric slide 202 has a support groove inside that matches the connecting column 207, and the contact surface between the top of the connecting column 207 and the bottom of one side of the fixed column 303 is set as a conical surface. The electric slide 202 has a support groove inside that matches the connecting column 207, and the contact surface between the top of the connecting column 207 and the bottom of one side of the fixed column 303 is set as a conical surface, which facilitates the movement of the connecting column 207 to contact the fixed column 303, and pushes the fixed column 303 to compress the return spring 304 to retract and move.

[0035] The working principle of this practical application is as follows:

[0036] Refer to the instruction manual appendix Figures 1-4 The electric slide rail and electric slide table 202 work together to slide the electric slide table 202 to the leftmost position inside the lathe body 1, opening the protective door 101 and releasing the pressure on the connecting plate 201. The telescopic spring 203 returns to its original position and pushes the connecting plate 201 out of the lathe body 1. The movement of the connecting plate 201 drives the top support seat 204 to move, causing the support seat 204 to move and press against the tapered surface on the side of the support groove. This causes the support seat 204 to be compressed and the support spring 205 to contract and move from the support groove into the connecting plate 201, releasing the pressure on the limiting seat 206. The connecting spring 208 returns to its original position and pushes the limiting seat 206 to slide from the bottom of the electric slide table 202 into the lathe body 1. This completes the limiting and fixing of the electric slide table 202 inside the lathe body 1, preventing accidental operation of the electric slide table 202.

[0037] Refer to the instruction manual appendix Figures 1-4The limiting seat 206 is pushed to slide from the bottom of the electric slide table 202 into the lathe body 1 by the reset of the connecting spring 208. The movement of the limiting seat 206 drives the connecting columns 207 on both sides of the top to move, causing the connecting columns 207 to move downward and release the pressure on the fixed column 303. The fixed column 303 releases the pressure on the reset spring 304 at the same time. The reset spring 304 pushes the fixed column 303 to slide inside the electric slide table 202, causing the fixed column 303 to slide out from the inner wall of the docking strip 302. The connection between the docking strip 302 and the electric slide table 202 is released, which makes it easy for the staff to directly remove the waste box 301 from the top of the electric slide table 202, complete the disassembly and replacement of the waste box 301, and reduce the time for disassembly and replacement of the waste box 301.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
