Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical part processing, in particular to a cutting and polishing device for mechanical part processing. BACKGROUND

[0002] In the field of modern mechanical manufacturing, structural engineering and equipment assembly, metal pipes, bars and various types of fixed cross-section profiles are widely used as key structural support, transmission and connecting components. Usually, these materials need to be cut into specific length and angle segments according to design requirements, and then assembled through welding or other methods to build the final required mechanical parts or frame structures.

[0003] Traditional processing methods usually separate cutting and polishing processes. First, the operator uses a sawing machine, a grinding machine or a laser / plasma cutting device to cut and end-face cut the workpiece. After this process, burrs, slag or irregular edges may be generated on the cut end face. In order to ensure the quality and precision of subsequent welding or assembly, the cut end face must be treated twice, i.e. using an angle grinder, a sanding machine or other handheld or fixed polishing tools for deburring and surface finishing. This step-by-step processing mode has obvious defects: first, the process is dispersed, and the workpiece needs to be transferred between different devices or stations, which not only reduces production efficiency, but also increases the risk of cumulative error in workpiece clamping and positioning, affecting the size accuracy and consistency of the final product; second, the skill dependence of the operator is high, the labor intensity is large, and the debris and sparks generated during cutting and polishing can easily cause safety hazards to personnel and the environment; third, it is difficult to achieve one-time high-precision forming of complex end face shapes (such as non-vertical cross-section, specific angle bevel, etc.) and automatic matching of subsequent polishing.

[0004] In order to improve the level of automation, some devices with preliminary composite functions have appeared in the market, such as integrating cutting head and simple polishing unit on the same machine tool. However, such devices often have single function and poor adaptability. Specifically, 1. The cutting and polishing tools are mostly fixedly installed or manually replaced, the switching efficiency is low, different tools cannot be quickly and automatically called in the processing cycle, which seriously restricts the realization of continuous automatic production. 2. Usually only a single type of polishing head is provided, which is difficult to meet the work requirements of different materials, different cross-sectional shapes or different polishing requirements (such as rough grinding, fine grinding and polishing), and the process adaptability is limited. 3. The workpiece clamping and feeding mechanism and the tool head moving mechanism often cannot provide high degree of freedom and high precision collaborative motion of multi-axis linear feeding and workpiece rotation feeding around the shaft, which limits the ability when processing complex spatial curved surface end face or performing inclined cutting and polishing. 4. For the switching drive of multiple polishing heads and the power transmission of cutting and polishing operations, multiple independent motors or complex mechanical transmission chains are usually used, the system structure is bulky, the control is complex, and the reliability needs to be improved.

[0029] The beneficial effects of the present application are as follows:

[0030] 1.

This allows for fully automatic, rapid, and accurate tool switching and power connection between different processing steps, without manual intervention, meeting the flexible production needs of small batches and multiple varieties.

[0033] 4. In the positioning and feeding module, the transverse and longitudinal positioning components drive symmetrically arranged transmission rollers via bidirectional lead screws, enabling concentric clamping of the workpiece from four directions. This ensures the workpiece axis coincides with the rotation axis, laying the foundation for high-precision feeding. The X-axis feed component transmits power stably to the movable clamping transmission rollers via a splined shaft and bevel gears, achieving stable linear transport of the workpiece while it is clamped. Notably, after the workpiece is cut, the differential speed at both ends can be controlled to separate the cut surfaces, creating working space for the grinding head. Attached Figure Description

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0051] Embodiment 1

[0052] Please refer to Figures 1-4 , Figure 10 , Figure 11 , a cutting and polishing device for machining mechanical parts, comprising:

[0053] The positioning and feeding module 1 comprises two coaxially and symmetrically arranged groups. The two groups of positioning and feeding modules 1 are used for clamping and positioning the cut workpiece, and adjusting the linear feeding of the workpiece in the X-axis direction and the rotation of the workpiece around the workpiece axis.

[0054] The cutting head 2, grinding head 3, and switching module 4 are included. The switching module 4 includes a primary reversing component 41, a secondary reversing component 42, and a drive component 43. The cutting head 2 and the secondary reversing component 42 are both mounted on the primary reversing component 41 and their positions are switched. The secondary reversing component 42 is equipped with multiple grinding heads 3 of different models and its position is switched so that a specific grinding head 3 can be adjusted to the working position. The drive component 43 can be poweredly connected to the grinding head 3 in the working position or the secondary reversing component 42 and drive it to run.

[0055] The dual-axis feed module 5 is assembled between two sets of positioning and feeding modules 1 and is used to assemble the switching module 4. The dual-axis feed module 5 is used to drive the switching module 4 to perform linear feed along the Y-axis or Z-axis.

[0056] The cutting and grinding device provided in this solution is typically used to process mechanical parts such as metal pipes and profiles with fixed cross-sections. After cutting the end face of the workpiece into a specific shape according to the design requirements, the cut sections of the workpiece can be assembled and welded at a specific angle to form a mechanical structure of a specific size and shape, which can then be used as a structural support, power transmission component, or equipment assembly for various purposes.

[0057] During the specific processing stage, the two sets of coaxially symmetrically arranged positioning and feeding modules 1 can stably clamp and position the workpiece with a fixed cross section along its own axis, and drive it to make stable linear feed along its own axis (i.e., the X-axis). The two sets of positioning and feeding modules 1 can also adjust the rotation of the clamped and positioned workpiece around its own axis, thereby realizing the rotational feed in the X-axis.

[0058] The dual-axis feed module 5 can drive the cutting head 2, grinding head and switching module 4 mounted on it to feed linearly and stably along the Y and Z axes. With the cooperation of the dual-axis feed module 5 and the positioning and feeding module 1, linear feed of the X, Y and Z axes and rotational feed of the X axis are realized to cut the workpiece into a specific shape of end face structure, so as to allow multiple sections of the cut workpiece to be assembled and welded in a specific posture.

[0059] For the switching module 4 assembled on the dual-axis feed module 5, when the first-stage reversing component 41 is running, it can switch the position of the cutting head 2 and the switching module 4 equipped with various grinding heads 3, so that the cutting head 2 or the grinding head 3 faces the conveyed workpiece at a specific angle. The cutting head 2 completes the precise cutting of the workpiece, and the grinding head 3 completes the efficient grinding and smoothing of the cut end face to remove the burrs left by the cutting so that the welding work can proceed stably.

[0060] It should be noted that the switching module 4 can also adjust the inclination angle of the cutting head 2 and the grinding head 3 in the working position (the angle between the axis of the cutting head 2 and the grinding head 3 and the Z axis), and when cutting and grinding profiles with complex cross sections, the cutting head 2 and the grinding head 3 can be inclined to act on the workpiece, thereby improving the applicability of the cutting and grinding device.

[0061] The driving assembly 43 can realize power shunt transmission to drive the secondary reversing assembly 42 and the grinding head 3 in the working position to operate independently. When driving the secondary reversing assembly 42 to operate independently, the position of the grinding head 3 can be adjusted to move the grinding head 3 of a specific model to the working position, and then drive the grinding head 3 in the working position to operate independently to realize efficient grinding of the cutting end face.

[0062] Embodiment 2

The front side of the installation hood 6 is provided with an operation window 61, and the two sides of the installation hood 6 are provided with feeding through openings 62 coaxially aligned with the positioning and feeding module 1.

[0065] The installation of the installation hood 6 can ensure that the positioning and feeding module 1 and the dual-axis feeding module 5 are stably assembled according to the designed spatial layout, thereby ensuring that the modules can cooperate to realize effective cutting and grinding of the workpiece. The operation window 61 can facilitate maintenance and cutting scrap cleaning operations of the above-mentioned modules. The feeding through openings 62 can ensure that the workpiece extends into or out of the two sides of the installation hood 6, thereby ensuring that the positioning and feeding module 1 can effectively receive and transmit the workpiece.

[0066] When cutting and grinding the workpiece, the operation opening is in a closed state to prevent the cutting and grinding process from producing debris that splashes outward.

[0067] A leveling foot 63 is also assembled at the bottom of the installation hood 6. By independently adjusting the leveling feet, the positioning and feeding module 1 and the dual-axis feeding module 5 can be accurately arranged in the horizontal direction.

[0068] Embodiment 3

The two positioning and feeding modules 1 are also provided with a speed reducer motor 134, which is in power connection with the connecting shaft 133.

[0072] The mounting base 11 is fixedly mounted in the mounting cover 6, and the outer gear ring 131 fixed to the rotary seat 12 is arranged outside the mounting base 11. The mounting base 11 can prevent the splashed debris from being embedded therein and affecting the feeding accuracy of the rotary feeding assembly 13.

[0073] The speed reducer motor 134 drives the connecting shaft 133 and the drive gear 132 to rotate synchronously, thereby driving the rotary seat 12 and the assemblies assembled thereon in the two positioning and feeding modules 1 to rotate coaxially, thereby ensuring the stable rotary feeding of the clamped and positioned workpiece in the X-axis direction.

[0074] The cooperation of the transverse positioning assembly 14 and the longitudinal positioning assembly 15 can effectively clamp and position the workpiece, and the cooperation of the X-axis feeding assembly 16 can drive the workpiece to stably feed in the X-axis direction.

[0075] In order to ensure that the transverse positioning assembly 14 and the longitudinal positioning assembly 15 can be stably assembled on the rotary seat 12 and effectively clamp and position the workpiece arranged in the assembly opening 121, the following technical solutions are provided.

The two sections of thread grooves are rotatably connected with the corresponding sliding supports A145 and the sliding supports B155, so as to drive the two sets of sliding supports A145 and the sliding supports B155 to always keep reverse equidistance operation. Then, the workpiece is effectively clamped and positioned by cooperation of the assembled transmission rollers A141 and the transmission rollers B151, so as to make the axis of the workpiece coincide with the axis of the rotating seat 12, and then realize stable linear feeding and rotating feeding of the workpiece along the X axis.

[0080] The same end of the two sets of adjusting lead screws A142 is fixedly connected with synchronous wheels A146. The two sets of synchronous wheels A146 realize synchronous operation through a synchronous belt. The adjusting motor A144 is directly connected with one of the two sets of adjusting lead screws A142.

The adjusting motor A144 and the adjusting motor B154 are fixedly installed in the rotating seat 12.

[0082] It should be noted that, in order to avoid the spatial motion interference of the sliding support A145, the sliding support B155 and the transmission rollers A141 and B151 arranged thereon, the sliding support A145 and the sliding support B155 are provided with a clearance opening, so as to ensure that the sliding support A145 and the sliding support B155 do not interfere with each other in the three-dimensional space, and the transmission rollers A141 and B151 are arranged in the X-axis direction, so as to ensure the stable operation of the horizontal positioning assembly 14 and the longitudinal positioning assembly 15.

[0083] In order to ensure that the X-axis feeding assembly 16 can be connected with the power of the horizontal positioning assembly 14 and the longitudinal positioning assembly 15, and drive the transmission rollers A141 and B151 to keep synchronous rotation, so as to drive the clamped and positioned workpiece to stably feed along the X-axis, the following technical solutions are provided.

The spline shaft A161 and the spline shaft B162 are both rotatably installed in the assembly opening 121 and are parallel to the guide shaft A143 and the guide shaft B153 respectively. The drive motor A163 and the drive motor B164 are connected with the spline shaft A161 and the spline shaft B162 respectively.

[0085] The drive bevel gear A165 and the drive bevel gear B166 are rotatably installed on the sliding support A145 and the sliding support B155 respectively, and are slidably connected with the spline shaft A161 and the spline shaft B162 respectively. The groups of transmission rollers A141 arranged on the sliding support A145 are connected with each other, and the groups of transmission rollers B151 arranged on the sliding support B155 are connected with each other. One of the groups of transmission rollers A141 arranged on the sliding support A145 is fixedly connected with a transmission bevel gear A147 which is engaged with the drive bevel gear A165, and one of the groups of transmission rollers B151 arranged on the sliding support B155 is fixedly connected with a transmission bevel gear B157 which is engaged with the drive bevel gear B166.

[0086] The same end of each group of transmission rollers A141 is fixed with a synchronous wheel a148, and each group of synchronous wheels a148 arranged on the same sliding bracket A145 is synchronized by a synchronous belt. The same end of each group of transmission rollers B151 is fixed with a synchronous wheel b158, and each group of synchronous wheels b158 arranged on the same sliding bracket B155 is synchronized by a synchronous belt.

[0087] Since the spline shaft A161 and the transmission roller A141 are vertically distributed, the spline shaft B162 and the transmission roller B151 are vertically distributed, so that through the combination of the driving bevel gear A165 and the transmission bevel gear A147, and the driving bevel gear B166 and the transmission bevel gear B157, the power of the spline shaft A161 and the spline shaft B162 can be stably transmitted to each group of transmission rollers A141 and transmission rollers B151, thereby ensuring that each group of transmission rollers A141 and transmission rollers B151 always operates stably.

[0088] It should be noted that the driving bevel gears A165 arranged on the two groups of sliding brackets A145 are symmetrically arranged, the driving bevel gears B166 arranged on the two groups of sliding brackets B155 are symmetrically arranged, when the power is transmitted to each transmission roller A141 and transmission roller B151, it can ensure that the transmission rollers A141 arranged on the two groups of sliding brackets A145 operate reversely and at the same speed, and ensure that the transmission rollers B151 arranged on the two groups of sliding brackets B155 operate reversely and at the same speed, and when the driving motor A163 and the driving motor B164 are controlled to operate at the same speed, the workpiece clamped between each transmission roller A141 and transmission roller B151 can be stably and linearly fed along the X-axis.

[0089] After the workpiece is cut off by the cutting head 2, the differential operation of the X-axis feeding assembly 16 in the two positioning and feeding modules 1 can separate the workpieces at both ends from the fracture, thereby facilitating the extension of the polishing head 3 driven by the double-shaft feeding module 5 into the fracture position, and realizing efficient polishing of the cutting port under the operation of each feeding component.

[0091] Please refer to Figure 1 、 Figure 10 In order to ensure that the double-shaft feeding module 5 can drive the switching module 4 arranged thereon and the cutting head 2 and the polishing head 3 can be stably fed along the Y-axis and the Z-axis, the following technical solutions are provided.

[0092] The double-shaft feeding module 5 includes a Y-axis feeding assembly 51 and a Z-axis feeding assembly 52, the Z-axis feeding assembly 52 is assembled to the movable component of the Y-axis feeding assembly 51, and the switching module 4 is assembled to the movable component of the Z-axis feeding assembly 52.

[0093] The Y-axis feeding assembly 51 and the Z-axis feeding assembly 52 are provided with linear motion mechanisms of screw and sliding block as position adjustment, so as to realize accurate feeding and position adjustment in the Y-axis and the Z-axis, and ensure accurate cutting and efficient polishing of the workpiece by the switching module 4, the cutting head 2 and the polishing head 3.

[0094] Embodiment 5

[0095] Please refer to Figures 10-15 In order to ensure that the primary reversing assembly 41 can be stably assembled on the Z-axis feeding assembly 52 and perform reversing adjustment, and ensure that the secondary reversing assembly 42 and the cutting head 2 can be stably assembled on the primary reversing assembly 41 and cooperate with reversing, the following technical solutions are provided.

[0096] The primary reversing assembly 41 comprises a reversing support 411 and a reversing motor 412, both of which are assembled to the movable part of the Z-axis feeding assembly 52, and the reversing motor 412 is in power connection with the reversing support 411, and the secondary reversing assembly 42 and the cutting head 2 are assembled to the two ends of the reversing support 411, respectively.

[0097] The reversing motor 412 is matched with a reduction gear box 413 with one-way self-locking, so as to amplify the torque of the reversing motor 412 and drive the reversing support 411 to stably operate, and after the reversing work is completed, the reversing motor 412 is stopped, so that the cutting head 2 and the secondary reversing assembly 42 can be maintained in a specific posture for work.

[0098] The reversing head adopts a laser cutting machine, which can accurately and efficiently cut the workpiece by means of the energy of laser gathering.

[0099] In order to ensure that the secondary reversing assembly 42 can be stably assembled on the reversing support 411 and realize accurate reversing of each group of polishing heads 3, the following technical solutions are provided.

[0100] The secondary reversing assembly 42 comprises a rotating disc 421, a positioning clamp 422 and a matched combination of a worm wheel 423 and a worm 424, the rotating disc 421 is rotatably installed on the reversing support 411, a plurality of groups of positioning clamps 422 are rotatably installed on the reversing support 411 in a ring array, each group of positioning clamps 422 is fixedly installed with a polishing head 3 arranged outside the rotating disc 421, the worm wheel 423 and the worm 424 are rotatably installed on the reversing support 411 and arranged in the rotating disc 421, the worm 424 is coaxially arranged with the polishing head 3 in the working position, the worm wheel 423 is coaxially fixedly connected with a transmission gear A 425, and the shaft center of the rotating disc 421 is fixedly connected with a transmission gear B 426 in meshing connection with the transmission gear A 425.

[0101] The polishing head 3 in the working position is arranged in the same axial direction as the cutting head 2, and each polishing head 3 and the corresponding positioning clamp 422 are arranged in the radial direction of the rotating disc 421, and the worm 424 is coaxially arranged with the rotating disc 421, so the axis of the worm wheel 423 is necessarily eccentrically arranged with the axis of the rotating disc 421, and the power of the worm wheel 423 can be stably transmitted to the rotating disc 421 and stably rotated around the axis of the rotating disc 421 through the cooperation of the transmission gear A 425 and the transmission gear B 426.

[0102] The transmission gear A 425 and the transmission gear B 426 are helical gears or herringbone gears, which can ensure uninterrupted and stable transmission of power to improve the stability of the rotating disc 421 in switching the positioning clamp 422 and the polishing head 3 thereon. Moreover, the cooperation of the worm wheel 423 and the worm 424 also has the characteristics of speed reduction, torque increase and one-way self-locking. When the worm 424 is in a stationary state, the worm wheel 423 is limited by the worm 424, so that it always remains stationary with the rotating disc 421, thereby ensuring stable power transmission between the driving assembly 43 and the polishing head 3 and the positioning clamp 422 at the working station.

[0103] To ensure stable assembly of the driving assembly 43 and realize stable power connection with the secondary reversing assembly 42 and the polishing head 3, the following technical solutions are provided.

[0104] The driving assembly 43 includes a driving motor C 431, a driving shaft 432, a transmission shaft 433, a lock joint 434, a spline shaft C 435, an electromagnet 436, a permanent magnet 437, and two sets of oppositely arranged ratchet mechanisms 438. The driving motor C 431 is fixedly installed on the reversing support 411. The driving shaft 432 is arranged through the axis of the worm 424 and is in power connection with the driving motor C 431. The input ends of the two sets of ratchet mechanisms 438 are in power connection with the driving shaft 432. The output ends of the two sets of ratchet mechanisms 438 are in power connection with the worm 424 and the transmission shaft 433, respectively. The transmission shaft 433 is provided with the electromagnet 436 on the periphery. The spline shaft C 435 is coaxially fixedly connected with the lock joint 434 and is slidingly inserted into the axis of the transmission shaft 433. The permanent magnet 437 is fixedly installed on the lock joint 434 and is coaxially opposite to the electromagnet 436. Each positioning clamp 422 is fixedly provided with a lock groove 427 which can be nested with the lock joint 434.

[0105] The output shaft of the driving motor C431 can be directly coaxially coupled with the driving shaft 432, or be power-connected through the bevel gear set 4311 due to the layout limitation, so as to drive the driving shaft 432 to stably rotate. The ratchet mechanism 438 comprises an inner ratchet 4381 and a pawl 4382 in meshing cooperation with the inner ratchet 4381. The pawl 4382, as a power input end, is assembled to the periphery of the driving shaft 432 and is driven by the matched spring piece 4383 to expand outwardly and be in meshing cooperation with the corresponding inner ratchet 4381. The inner ratchets 4381 in the two groups of ratchet mechanisms 438 are respectively fixedly connected with the worm 424 and the transmission shaft 433.

[0106] When the driving shaft 432 rotates forward or reversely, the worm 424 and the transmission shaft 433 can be independently rotated. Since the spline shaft C435 is in sliding insertion with the transmission shaft 433, the spline shaft C435 and the locking head can always receive the power of the transmission shaft 433 for synchronous rotation.

[0107] The electromagnet 436 is fixedly installed on the reversing support 411. By inputting opposite currents, the electromagnet 436 can exert attractive force and repulsive force on the locking head 434 assembled with the permanent magnet 437. When the electromagnet 436 pushes the permanent magnet 437 and the locking head 434 to extend outwardly, the locking head 434 can be in matched locking cooperation with the locking groove 427 on the polishing head 3 in the working position and the corresponding positioning clamp 422, so as to stably transmit the power to the polishing head 3. When the electromagnet 436 attracts the permanent magnet and the locking head 434 to retract inwardly, the locking head 434 is separated from the corresponding locking groove 427. At this time, the rotating disc 421 can be stably rotated after inputting power and replace the polishing head 3.

[0108] In order to avoid rigid collision of the permanent magnet 437 when approaching the electromagnet 436, a buffer rubber pad 4361 can be assembled to the outer side end of the permanent magnet 437.
