Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing and processing technology, specifically to a combination machine tool for mechanical manufacturing. Background Technology

[0002] In the field of mechanical manufacturing and processing technology, modular machine tools, as equipment integrating multiple processing functions, occupy an important position in mass production and precision machining scenarios. However, existing technical solutions still have many problems that urgently need to be solved in practical applications. The worktable support structure of traditional modular machine tools is often relatively simple, relying on a single support component for support, lacking effective reinforcement design. During long-term machining or handling heavy workpieces, uneven force can easily cause wobbling or even slight deformation. Vibration generated by the motor during machining further exacerbates this instability, affecting not only the workpiece clamping effect but also potentially leading to a decrease in machining accuracy. Regarding workpiece clamping, common clamping structures often use hard materials in direct contact with the workpiece. If the clamping force is not properly controlled, it can easily cause indentations, scratches, and other damage to precision parts or easily damaged surfaces. Simultaneously, some clamping structures lack sufficient friction, allowing the workpiece to slip during machining, further affecting machining quality. In the rotary machining stage… Components that perform rotational functions typically rely on a single shaft for support and positioning. When the workpiece above is heavy or the rotation frequency is high, the shaft is prone to bending and deformation due to long-term stress, leading to misalignment during rotation and consequently, machining position deviations. During drilling operations, the debris generated lacks effective containment measures and easily scatters, posing a safety threat to operators, polluting the processing environment, and increasing the difficulty of subsequent cleaning. Furthermore, the surface of the machined workpiece often retains debris and dust, requiring manual cleaning in most existing equipment. This not only increases labor costs and prolongs the overall processing cycle but also reduces processing efficiency. Moreover, manual cleaning is difficult to guarantee uniformity of cleaning results, potentially affecting subsequent processes. These combined problems make it difficult for traditional combination machine tools to meet the high standards of modern mechanical manufacturing and processing in terms of processing stability, accuracy, operational safety, and efficiency.

[0003] To address this issue, we propose a modular machine tool for mechanical manufacturing. Summary of the Invention

[0004] To address the aforementioned problems, a combined machine tool for mechanical preparation is provided to solve the issues described in the background art.

[0005] To address the problems of existing technologies, this invention provides a combined machine tool for mechanical preparation, comprising a worktable arranged horizontally, a large gear positioned directly above the worktable, a rotating shaft fixedly mounted on the bottom surface of the large gear, the end of the rotating shaft away from the large gear movably penetrating through the top surface of the worktable and extending to a position below the worktable, a motor fixedly mounted at the bottom end of the rotating shaft, a cross-shaped machining table fixedly mounted on the top surface of the large gear, the top surface of the cross-shaped machining table having a cross-shaped groove, an electric telescopic rod fixedly mounted on the inner wall of the cross-shaped groove, a clamping plate fixedly mounted at the end of the electric telescopic rod, an L-shaped fixing frame fixedly mounted on the top surface of the worktable, a drilling assembly fixedly mounted on the lower surface of the L-shaped fixing frame, and a pair of cleaning components fixedly mounted on the top surface of the worktable.

[0006] As a technical solution of the present invention, support legs are fixedly installed at the bottom of the four corners of the worktable, and feet are fixedly installed at the bottom of the support legs. A first reinforcing rod is fixedly installed between the support legs located at the front and rear positions, and a second reinforcing rod is fixedly installed between the support legs located at the left and right positions. The support legs fixedly installed at the bottom of the four corners of the worktable can provide stable support for the entire device. The support legs, together with the feet, can not only stably support the overall weight of the worktable, but also adjust the level of the equipment through the feet to adapt to different ground environments. The first and second reinforcing rods form a "lateral + longitudinal" reinforcement network, which greatly improves the deformation resistance of the support legs, avoids structural shaking caused by vibration during machine tool processing, and ensures processing accuracy.

[0007] As a technical solution of the present invention, a motor base is fixedly installed on the bottom surface of the motor, and the top of the motor base is fixedly installed on the bottom surface of the worktable. The motor base rigidly connects the motor and the worktable, avoiding the direct transmission of high-frequency vibrations from the motor during operation to the worktable and reducing the impact of vibrations on the processed parts.

[0008] As a technical solution of the present invention, the side of the clamping plate away from the electric telescopic rod is made of rubber. The rubber material increases the friction between the clamping plate and the workpiece, improves the clamping stability, and prevents the workpiece from sliding during processing. The rubber is elastic and can buffer the clamping force, avoiding indentations or damage to the workpiece surface caused by hard contact. It is especially suitable for precision parts or parts with easily damaged surfaces.

[0009] As a technical solution of the present invention, a support ring is fixedly installed on the bottom surface of the large gear. The lower end of the support ring is rotatably configured with an annular groove opened on the top surface of the worktable. The support ring and the annular groove form an "auxiliary support + guide" structure, which shares the weight of the large gear and the cross-shaped processing table above, and prevents the shaft from bending due to excessive load. The annular groove provides rotational guidance for the support ring, ensuring the coaxiality of the large gear when it rotates, and preventing processing errors caused by the offset of the processing table.

[0010] As one technical solution of the present invention, the drilling assembly includes a cylinder, the top surface of which is fixedly installed on the lower surface of an L-shaped fixing frame, and a drilling machine is fixedly installed at the bottom end of the cylinder. An auxiliary column is fixedly sleeved on the outer wall of the drilling machine, and the outer wall of the auxiliary column has an annular groove. A protective cover is slidably installed in the annular groove. The cylinder drives the drilling machine to rise and fall, which can flexibly adjust the drilling depth to meet the processing requirements of workpieces of different thicknesses. During drilling, the protective cover first contacts the workpiece surface and moves down with the drilling machine to compress the connecting spring, forming a closed space to block the flying debris generated during drilling and protect the operator's safety.

[0011] As a technical solution of the present invention, a connecting spring is slidably sleeved on the annular groove of the outer wall of the auxiliary column. The bottom end of the connecting spring is fixedly installed on the top surface of the protective cover, and the top of the inner wall of the annular groove at the end of the connecting spring away from the protective cover is fixedly installed. The elastic reset function of the connecting spring can drive the protective cover to automatically reset when the drilling machine is raised, without affecting the workpiece loading and unloading.

[0012] As one technical solution of the present invention, the cleaning component includes a small gear, an mounting shaft is fixedly installed on the inner wall of the small gear, the bottom end of the mounting shaft is rotatably connected to the top surface of the worktable through a bearing, a cleaning roller is fixedly sleeved on the outer wall of the mounting shaft, the outer wall of the cleaning roller has a rectangular groove, a small spring is fixedly installed on the inner wall of the rectangular groove, a cleaning plate is fixedly installed on one end of the small spring, and bristles for cleaning mechanical parts after drilling are fixedly installed on the outer wall of the cleaning plate. The small spring pushes the cleaning plate so that the bristles closely adhere to the surface of the workpiece, adapting to the cleaning needs of workpieces of different shapes.

[0013] As one technical solution of the present invention, the longitudinal length of the cleaning plate is less than the longitudinal length of the rectangular groove, and the transverse width of the cleaning plate is less than the transverse width of the rectangular groove. The size of the cleaning plate is smaller than that of the rectangular groove, leaving room for expansion and contraction. This avoids damage caused by excessive compression of the bristles when the workpiece size deviates, while ensuring uniform cleaning pressure. At the same time, it provides sufficient expansion and contraction allowance for the cleaning plate, ensuring that the small spring can drive the cleaning plate to flexibly adjust its position to adapt to the cleaning of workpieces of different sizes. This avoids the cleaning plate getting stuck on the inner wall of the rectangular groove, ensures the smoothness of the cleaning roller rotation, and maintains a stable cleaning effect.

[0014] The advantages of this invention compared to the prior art are: 1. The worktable in this application achieves stable support through support legs and feet, and forms a reinforced structure with horizontal and vertical reinforcing bars, effectively reducing vibration and shaking during processing; the motor is rigidly connected to the worktable through the motor base, avoiding the transmission of high-frequency vibration during operation to the worktable, further reducing interference with the processing process; the rubber clamps on the cross-shaped processing table can tightly clamp the workpiece, preventing the workpiece from sliding and avoiding clamping damage through elastic buffering, ensuring the stability of the processing process from three aspects: equipment support, power source vibration reduction, and workpiece fixation.

[0015] 2. In this application, the support ring at the bottom of the large gear and the annular groove of the worktable form an auxiliary support and rotation guide structure, which ensures rotational coaxiality while sharing the weight and avoids the cross-shaped processing table from shifting; the cylinder in the drilling assembly drives the drilling machine to lift and lower, which can accurately control the drilling depth, and the stable positioning of the guard when it contacts the workpiece indirectly assists in the accuracy of the drilling position; the cleaning plate of the cleaning assembly, under the action of a small spring, can make the bristles evenly adhere to the workpiece surface, avoiding workpiece displacement caused by uneven force during the cleaning process. Multiple links work together to ensure processing accuracy.

[0016] 3. During drilling, the protective cover moves down with the drilling machine to form a closed space, blocking debris from splashing and protecting the operator's safety. The connecting spring can drive the protective cover to automatically reset without affecting the workpiece loading and unloading. The cleaning component achieves automatic rotation cleaning through the meshing of large and small gears, without manual intervention, reducing subsequent cleaning steps. In the entire processing flow, the transfer of workpieces is completed by the rotation of the motor-driven processing table, without manual handling, improving the overall processing efficiency from both safety protection and automated operation perspectives.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1-9As shown, a combination machine tool for mechanical preparation includes a worktable 1 arranged horizontally. Support legs 2 are fixedly installed at the bottom of each of the four corners of the worktable 1, and feet are fixedly installed at the bottom of each support leg 2. A first reinforcing rod 3 is fixedly installed between the front and rear support legs 2, and a second reinforcing rod 4 is fixedly installed between the left and right support legs 2. The support legs 2 fixedly installed at the bottom of the four corners of the worktable 1 provide stable support for the entire device. The support legs 2, together with the feet, not only stably support the overall weight of the worktable 1, but also allow for adjustment of the equipment's level to adapt to different ground environments. The first and second reinforcing rods form a "horizontal + longitudinal" reinforcement network, significantly improving the deformation resistance of the support legs 2 and preventing vibration during machine processing. To prevent structural wobbling and ensure machining accuracy, a large gear 8 is positioned directly above the worktable 1. A rotating shaft 6 is fixedly mounted on the bottom surface of the large gear 8. The end of the rotating shaft 6 away from the large gear 8 extends through the top surface of the worktable 1 and down to the bottom of the worktable 1. A motor 5 is fixedly mounted on the bottom end of the rotating shaft 6. A motor base 7 is fixedly mounted on the bottom surface of the motor 5. The top of the motor base 7 is fixedly mounted to the bottom surface of the worktable 1, rigidly connecting the motor 5 and the worktable 1. This prevents the high-frequency vibration of the motor 5 from being directly transmitted to the worktable 1, reducing the impact of vibration on the machined parts. A cross-shaped machining table 12 is fixedly mounted on the top surface of the large gear 8. The top surface of the cross-shaped machining table 12 has a cross-shaped groove, and an electric extension is fixedly mounted on the inner wall of the cross-shaped groove. The telescopic rod 13 has a clamping plate 14 fixedly installed at its end. The side of the clamping plate 14 away from the telescopic rod 13 is made of rubber. The rubber material increases the friction between the clamping plate 14 and the workpiece, improves clamping stability, and prevents the workpiece from slipping during processing. The rubber is elastic and can buffer the clamping force, avoiding indentations or damage to the workpiece surface caused by hard contact. It is especially suitable for precision parts or parts with easily damaged surfaces. A support ring 15 is fixedly installed on the bottom surface of the large gear 8. The lower end of the support ring 15 is rotatably set with an annular groove 16 opened on the top surface of the worktable 1. The support ring 15 and the annular groove 16 form an "auxiliary support + guide" structure, which shares the weight of the large gear 8 and the cross-shaped processing table 12 above it, preventing the shaft from bending due to excessive load. The annular groove is the support ring 15. 5 provides rotational guidance to ensure the coaxiality of the large gear 8 during rotation and prevent machining errors caused by table offset. An L-shaped fixing frame 9 is fixedly installed on the top surface of the worktable 1, and a drilling assembly 10 is fixedly installed on the lower surface of the L-shaped fixing frame 9. The drilling assembly 10 includes a cylinder 101, the top surface of which is fixedly installed with the lower surface of the L-shaped fixing frame 9. A drilling machine 102 is fixedly installed at the bottom end of the cylinder 101. An auxiliary column 103 is fixedly sleeved on the outer wall of the drilling machine 102. The outer wall of the auxiliary column 103 has an annular groove, and a protective cover 105 is slidably installed in the annular groove. The cylinder 101 drives the drilling machine 102 to rise and fall, which can flexibly adjust the drilling depth to meet the processing requirements of workpieces of different thicknesses. During drilling, the protective cover 105 contacts the workpiece surface first.As the drilling machine 102 moves downward, a closed space is formed, blocking the flying debris generated during drilling and protecting the operator's safety. A connecting spring 104 is slidably fitted onto the annular groove on the outer wall of the auxiliary column 103. The bottom end of the connecting spring 104 is fixedly installed on the top surface of the protective cover 105, and the top of the annular groove inner wall at the end of the connecting spring 104 away from the protective cover 105 is also fixedly installed. The elastic reset function of the connecting spring 104 allows the protective cover 105 to automatically reset when the drilling machine 102 is raised, without affecting the loading and unloading of workpieces. A pair of cleaning components 11 are fixedly installed on the top surface of the worktable 1. Each cleaning component 11 includes a pinion 111, and an mounting shaft 112 is fixedly installed on the inner wall of the pinion 111. The bottom end of the mounting shaft 112 is rotatably connected to the top surface of the worktable 1 via a bearing 113. A cleaning roller 114 is fixedly fitted onto the outer wall of the mounting shaft 112. The outer wall of the cleaning roller 114 has a rectangular groove 115, and a small spring 116 is fixedly installed on the inner wall of the rectangular groove 115. A cleaning plate 117 is fixedly mounted on one end of a spring 116. The outer wall of the cleaning plate 117 is fixedly fitted with bristles (not shown in the figure) for cleaning the drilled mechanical parts. The small spring 116 pushes the cleaning plate 117, causing the bristles to fit tightly against the workpiece surface, adapting to the cleaning needs of workpieces of different shapes. The longitudinal length of the cleaning plate 117 is less than the longitudinal length of the rectangular groove 115, and the transverse width of the cleaning plate 117 is less than the transverse width of the rectangular groove 115. The size of the cleaning plate 117 is smaller than that of the rectangular groove 115, leaving room for expansion and contraction to avoid damage caused by excessive pressure on the bristles when the workpiece size deviates. This also ensures uniform cleaning pressure and provides sufficient expansion and contraction allowance for the cleaning plate 117, ensuring that the small spring 116 can flexibly adjust the position of the cleaning plate 117 to adapt to the cleaning of workpieces of different sizes, preventing the cleaning plate 117 from jamming against the inner wall of the rectangular groove 115, ensuring smooth rotation of the cleaning roller 114, and maintaining a stable cleaning effect.

[0029] In use, the mechanical part to be processed is placed on the cross-shaped processing table 12, and the electric telescopic rod 13 is activated, which pushes the clamping plates 14 to move towards the workpiece until the four clamping plates 14 clamp the workpiece. Here, the rubber clamping plates 14 can prevent damage to the workpiece. Then, the motor 5 drives the large gear 8 to rotate through the rotating shaft 6, and the cross-shaped processing table 12 on the top surface of the large gear 8 rotates synchronously with it (the support ring 15 rotates in the annular groove 16 to ensure rotational stability). When the workpiece rotates to directly below the drilling assembly 10, the motor 5 stops. At this time, the cylinder 101 pushes the drilling machine 102 to move down. The protective cover 105 first contacts the surface of the workpiece and compresses the connecting spring 104 to form a closed space. The drilling machine 102 continues to move down to drill the workpiece (the debris is blocked by the protective cover 105). (1) After drilling is completed, cylinder 101 drives drilling machine 102 to move upward, connecting spring 104 resets and causes guard 105 to rise synchronously; motor 5 starts again, driving the processing table to rotate to the position of cleaning component 11, large gear 8 meshes with small gear 111, driving cleaning roller 114 to rotate, cleaning plate 117, under the action of small spring 116, makes the bristles adhere to the surface of the workpiece to clean the debris after drilling (cleaning plate 117 can flexibly extend and retract in rectangular groove 115 to adapt to the shape of the workpiece); when cleaning is completed, cleaning component 11 stops working, electric telescopic rod 13 retracts and drives clamping plate 14 to move inward to the cross-shaped groove, releasing the clamping of the workpiece, and the operator can easily remove the processed and clean workpiece, and the entire processing process is completed.

[0030] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
