Description

Technical Field

[0001] This invention relates to the field of turning equipment technology, and more particularly to a turning machine for parts with a clamping mechanism. Background Technology

[0002] A turning machine is a type of metal cutting equipment with rotary motion as its core. Its core working principle is to drive the workpiece to complete high-speed rotation through the spindle, and combine it with the precise feed motion of the cutting tool along the axis or radial direction of the workpiece to perform shaping processing on rotating parts such as shafts and discs, as well as non-rotating parts that need to be rotated. The equipment can flexibly adapt to dedicated clamping and fixing mechanisms, cutting tool systems and control modes according to the material characteristics, dimensional accuracy requirements and processing scenario of the parts, and achieve high-precision shaping of parts from blanks to finished products through precise material removal.

[0003] For example, a turning machine with a clamping mechanism disclosed in CN115625360A first limits the conveying of the part by two sets of positioning blocks on the conveyor belt, and then clamps and feeds the part to the turning area to achieve the turning process. However, the clamping action surface of this clamping method is still limited to the same side of the two sets of positioning blocks, which can only achieve the effect of single-sided positioning and clamping. It lacks multi-directional positioning constraints, makes it difficult to achieve precise positioning and feeding, and reduces the accuracy of turning. At the same time, the installation position of the positioning blocks is fixed, which cannot adapt to the limiting and conveying requirements of parts of different specifications, thus limiting the applicability of the equipment.

[0004] To address the aforementioned technical deficiencies, a solution is proposed that utilizes a correction mechanism to automatically unify the placement posture of parts on the conveyor belt, avoiding clamping misalignment caused by initial posture deviations. Furthermore, by combining a clamping mechanism with a U-shaped conveyor table, multi-directional limiting is applied to the parts. This multi-stage approach, employing elastic positioning, adsorption anti-deviation, and rigid fixing, effectively addresses the problem that existing turning equipment cannot effectively position and fix parts of different sizes and irregular postures. Summary of the Invention

[0005] The purpose of this invention is to provide a turning machine with a clamping mechanism to solve the aforementioned technical defects.

[0006] The objective of this invention can be achieved through the following technical solution: a part turning machine with a clamping mechanism, including a U-shaped conveyor table and a conveyor belt installed inside the U-shaped conveyor table for conveying parts. Turning equipment for turning parts is respectively provided on both sides of the U-shaped conveyor table, and a positioning mechanism that performs multi-directional limiting processing of the parts on the conveyor belt in conjunction with the U-shaped conveyor table. A correction mechanism for correcting the posture of the parts is provided on one side of the U-shaped conveyor table located on the turning equipment.

[0007] Preferably, the positioning mechanism includes a fixed frame fixedly connected to one side of the U-shaped conveyor table, and movable rods with a <-shaped structure are symmetrically slidably connected to the top two sides of the fixed frame. One end of the movable rod is welded to a mounting frame, and a ﹞-shaped clamp is provided on the mounting frame. An electric push rod is fixedly installed on the fixed frame, and a mounting block is fixedly connected to the telescopic rod of the electric push rod. A connecting rod is hinged between the mounting block and the movable rod.

[0008] Preferably, the mounting frame is internally fixedly connected with a rotating shaft, a limiting rod, and a mounting rod arranged in a triangular pattern. An L-shaped clamping arm is rotatably connected to the rotating shaft, and the long end of the L-shaped clamping arm is rotatably connected to a corresponding U-shaped clamping plate. A tension spring is fixedly connected between the short end of the L-shaped clamping arm and the mounting rod, and a spring is fixedly connected between the L-shaped clamping arm and the U-shaped clamping plate.

[0009] Preferably, the free end of the mounting block is fixedly connected to an abutment plate, and a rubber cover is fixedly connected to one side of the abutment plate. Multiple abutment suction rods penetrating to the outside of the rubber cover are fixedly installed on the abutment plate, and an opening is provided at one end of the abutment suction rod. A rubber sealing ring is fixedly installed at the end of the abutment suction rod.

[0010] Preferably, two sets of hollow rods communicating with the inside of the rubber cover are fixedly connected to the contact plate and located on both sides of the mounting block. A sleeve that is slidably connected to the corresponding hollow rod is fixedly connected to the fixing frame. A piston block that is slidably connected to the inner wall of the sleeve is fixedly connected to the outer wall of the end of the hollow rod.

[0011] Preferably, a sliding sleeve is fixedly connected to the rubber cover and slidably and sealingly connected to the corresponding abutting adsorption rod, and a wire mesh cover is embedded in the side wall of the rubber cover.

[0012] Preferably, the correction mechanism includes a mounting frame fixedly connected to one side of the U-shaped conveyor table. A servo motor is fixedly mounted on the mounting frame by bolts, and a U-shaped frame is fixedly mounted on the output shaft of the servo motor. Cylinders are fixedly mounted on both sides of the U-shaped frame. A clamping plate that is slidably connected to the U-shaped frame is fixedly mounted at the piston rod end of the cylinder. A camera is fixedly mounted on the top inside the U-shaped frame, and a control panel is fixedly mounted on one side of the U-shaped conveyor table.

[0013] Preferably, the two sides of the U-shaped conveyor platform are symmetrically rotatably connected to rotating rollers that are connected to the conveyor belt, and the inside of the U-shaped conveyor platform is fixedly connected to a support plate that slides in contact with the top of the conveyor belt.

[0014] The beneficial effects of this invention are as follows:

[0015] (1) This invention utilizes the visual recognition of a camera and the linkage of a servo motor and cylinder to automatically unify the placement posture of parts on the conveyor belt, ensuring that the subsequent positioning mechanism can accurately act on the same side wall of the parts, avoiding clamping misalignment caused by initial posture deviation; then, through the electric push rod and connecting rod driving the movable rod to drive the mounting frame to move, in conjunction with the elastic structure composed of L-shaped clamping arm, tension spring and spring, it can achieve adaptive centering clamping of parts of different sizes, and push the parts closer to the inner wall of one side of the U-shaped conveyor table, assisting the abutment suction rod to combine with the inner wall of the U-shaped conveyor table to rigidly clamp the parts, thereby forming a multi-directional limiting and stable fixing effect, so as to avoid the risk of displacement of parts during turning. Through the step-by-step multi-stage combination of posture correction, elastic positioning and rigid fixing, it effectively solves the problem that existing turning equipment cannot effectively position and fix parts of different sizes and irregular postures.

[0016] (2) When the contact plate moves with the mounting block, the hollow rod drives the piston block to slide inside the sleeve, so that the rubber cover and the inside of the contact adsorption rod form a negative pressure environment. The end of the contact adsorption rod is sealed and attached to the surface of the part to achieve adsorption and fixation, so as to strengthen the anti-deviation positioning of the part before rigid clamping and prevent the part from sliding and shifting during clamping. Moreover, through the rubber sealing ring at the end of the contact adsorption rod, it adaptively fits the surface contour of the part and effectively fixes the part with slightly irregular surface, avoiding the displacement of the part with slightly irregular surface caused by rigid clamping, thereby ensuring the stability of the part position during turning and eliminating the machining error caused by unstable fixation.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1-4 and Figure 8 As shown, the existing clamping method can only achieve unilateral positioning and clamping, lacks multi-directional positioning constraints, makes it difficult to achieve precise positioning and feeding, and reduces the accuracy of turning machining. The following solutions can be used to address this problem:

[0032] This embodiment of a part turning machine with a clamping mechanism includes a U-shaped conveyor table 1 and a conveyor belt 11 installed inside the U-shaped conveyor table 1 for conveying parts. Turning equipment 12 for turning parts is respectively provided on both sides of the U-shaped conveyor table 1, and a positioning mechanism 2 for feeding and multi-directional limiting of parts on the conveyor belt 11 in conjunction with the U-shaped conveyor table 1. The vertical sections on both sides of the U-shaped conveyor table 1 have a height difference. The positioning mechanism 2 is installed on the lower vertical section and the turning equipment 12 is installed on the higher vertical section. The positioning mechanism 2, in conjunction with the higher vertical section, provides rigid clamping treatment for the parts. A correction mechanism 3 for correcting the posture of the parts is provided on one side of the turning equipment 12 on the U-shaped conveyor table 1.

[0033] The positioning mechanism 2 includes a fixed frame 21 fixedly connected to one side of the U-shaped conveyor table 1, and movable rods 22 with a <-shaped structure are symmetrically slidably connected to the top two sides of the fixed frame 21. When the two sets of movable rods 22 slide synchronously in the same direction through the <-shaped structure, they achieve the effect of synchronous relative tilting sliding. A mounting frame 23 is welded to one end of the movable rod 22, and a ﹞-shaped clamping plate 24 is provided on the mounting frame 23. The ﹞-shaped clamping plate 24 is used to maintain multi-linear stable clamping of the parts, thereby synchronously realizing the positioning and clamping of parts with slightly irregular surfaces.

[0034] An electric push rod 25 is fixedly installed on the fixed frame 21, and a mounting block 26 is fixedly connected to the telescopic rod of the electric push rod 25. A connecting rod 27 is hinged between the mounting block 26 and the movable rod 22. After the part moves with the conveyor belt 11 to the area between the two sets of U-shaped clamps 24, the electric push rod 25 pushes the mounting block 26 to move, and in conjunction with the connecting rod 27 hinged on both sides, pushes the two sets of movable rods 22 to tilt and slide relative to each other, causing the two sets of mounting frames 23 to move away from the fixed frame 21 while moving relative to each other. This causes the two sets of U-shaped clamps 24 to clamp the part in the center and push the part to move towards the inner wall of one side of the U-shaped conveyor table 1, further realizing secondary positioning processing.

[0035] The mounting frame 23 is internally fixedly connected to a rotating shaft 28, a limiting rod 29, and a mounting rod 210 arranged in a triangular pattern. An L-shaped clamping arm 211 is rotatably connected to the rotating shaft 28, and the long end of the L-shaped clamping arm 211 is rotatably connected to the corresponding ﹞-shaped clamping plate 24. A tension spring 212 is fixedly connected between the short end of the L-shaped clamping arm 211 and the mounting rod 210. Under the tension of the tension spring 212, one side of the L-shaped clamping arm 211 is forced to abut against the limiting rod 29, thereby limiting the initial position of the L-shaped clamping arm 211 so that the part is located in the area between the two sets of ﹞-shaped clamping plates 24.

[0036] When clamping parts, the L-shaped clamping arm 211 is rotatably connected to the mounting frame 23, and combined with the tension of the tension spring 212, it enables the elastic clamping and positioning of parts of different sizes, without interfering with the continuous movement of the mounting block 26 by the electric push rod 25. A spring 213 is fixedly connected between the L-shaped clamping arm 211 and the ﹞-shaped clamping plate 24 to elastically fix the initial angle of the ﹞-shaped clamping plate 24.

[0037] The free end of the mounting block 26 is fixedly connected to the abutment plate 214, and a rubber cover 215 is fixedly connected to one side of the abutment plate 214. Multiple abutment suction rods 216 that penetrate to the outside of the rubber cover 215 are fixedly installed on the abutment plate 214, and an opening 217 is opened at one end of the abutment plate 214. A rubber sealing ring is fixedly installed at the end of the abutment suction rod 216.

[0038] The mounting block 26 moves by carrying multiple abutment suction rods 216 through the abutment plate 214, causing the rubber sealing ring ends of the multiple abutment suction rods 216 to abut against one side of the part, further assisting in pushing the part to move. Then, combined with the U-shaped conveyor table 1 located on one side of the inner wall of the turning equipment 12, the part is centrally and rigidly clamped. Combined with the elastic positioning clamping of the initial ﹞-shaped clamping plate 24, a multi-directional limiting and stable fixing effect is formed to avoid the risk of displacement of the part during the turning process.

[0039] The correction mechanism 3 includes a mounting frame 31 fixedly connected to one side of the U-shaped conveyor table 1. A servo motor 32 is fixedly mounted on the mounting frame 31 by bolts, and a U-shaped frame 33 is fixedly mounted on the output shaft of the servo motor 32. Cylinders 34 are fixedly mounted on both sides of the U-shaped frame 33, and a clamping plate 35 that is slidably connected to the U-shaped frame 33 is fixedly mounted on the piston rod end of the cylinder 34.

[0040] The conveyor belt 11 transports multiple parts at intervals. When the parts are transported to the bottom of the U-shaped frame 33, the piston rods of the two sets of cylinders 34 move synchronously, pushing the corresponding clamping plate 35 to move and clamp the parts. Then, the servo motor 32 is controlled to deflect, which in turn drives the clamped parts to deflect, unifying the placement posture of multiple parts on the conveyor belt 11. This ensures that the subsequent positioning mechanism 2 can accurately act on the same side wall of the parts, avoiding clamping misalignment caused by initial posture deviation.

[0041] A camera 36 is fixedly installed on the top of the U-shaped frame 33, and a control panel 13 is fixedly installed on one side of the U-shaped conveyor table 1. The camera 36 takes pictures of the current placement posture of the parts and sends the image information to the controller in the control panel 13. The controller first controls the cylinder 34 and then controls the servo motor 32 to run.

[0042] The U-shaped conveyor table 1 has symmetrical rotating rollers on both sides that are connected to the conveyor belt 11. The rotating rollers are driven by an external motor, which in turn drives the conveyor belt 11 to rotate, realizing automatic loading and unloading of parts. The U-shaped conveyor table 1 has a fixed support plate 14 that slides in contact with the top of the conveyor belt 11. This plate supports the conveyor belt 11 above the rotating rollers, thereby providing stable support for the parts during the conveying, clamping, and turning processes.

[0043] Example 2: Please refer to Figure 3 and Figures 5-7 As shown, when positioning parts with slightly irregular surfaces, the combination of elastic positioning and rigid clamping can easily lead to slight positional deviations after the parts are fixed. This can be solved by the following solution:

[0044] In this embodiment, the free end of the mounting block 26 is fixedly connected to an abutment plate 214, and a rubber cover 215 is fixedly connected to one side of the abutment plate 214. Multiple abutment suction rods 216 that penetrate to the outside of the rubber cover 215 are fixedly installed on the abutment plate 214, and an opening 217 is provided at one end of the abutment plate 214. A rubber sealing ring is fixedly installed at the end of the abutment suction rod 216.

[0045] When the contact plate 214 moves, the rubber sealing ring at the end of the contact adsorption rod 216 contacts the part. By evacuating the inside of the rubber cover 215, the rubber cover 215 and the contact adsorption rod 216 are connected through the through port 217, resulting in a negative pressure environment inside the contact adsorption rod 216. The end of the contact adsorption rod 216 is sealed and adhered to the surface of the part to achieve adsorption and fixation, thereby strengthening the anti-deviation positioning of the part before rigid clamping and preventing the part from sliding and shifting during the clamping process.

[0046] The U-shaped conveyor table 1 is then rigidly clamped on one side of the inner wall to further stabilize the position of the part during the turning process. The rubber sealing ring at the end of the suction rod 216 adaptively conforms to the surface contour of the part and effectively fixes the part with slightly irregular surface, avoiding the displacement of the part with slightly irregular surface caused by rigid clamping. This ensures the stability of the part's position during the turning process and eliminates the machining error caused by unstable fixation.

[0047] Two sets of hollow rods 218 that communicate with the inside of the rubber cover 215 are fixedly connected to the contact plate 214 and located on both sides of the mounting block 26. A sleeve 219 that is slidably connected to the corresponding hollow rod 218 is fixedly connected to the fixing bracket 21. A piston block 220 that is slidably connected to the inner wall of the sleeve 219 is fixedly connected to the outer wall of the end of the hollow rod 218.

[0048] During the movement of the contact plate 214, it simultaneously carries the hollow rod 218 and the piston block 220 to slide inside the corresponding sleeve 219. The piston block 220 moves relatively away from the fixed frame 21 inside the sleeve 219. Combined with the hollow rod 218, the rubber cover 215, the port 217 and the contact suction rod 216, the air from the outside is drawn out. When the contact suction rod 216 contacts the part, it is adsorbed and fixed. As the piston block 220 moves, the negative pressure intensity is further increased to achieve stable adsorption and fixing. The negative pressure intensity inside the rubber cover 215 is continuously increased, which causes the rubber cover 215 to shrink and deform. While maintaining the negative pressure state, it avoids obstructing the movement of the contact plate 214 and avoids the inability to push the part to contact the inner wall of the U-shaped conveyor table 1.

[0049] A sliding sleeve is fixedly connected to the rubber cover 215 and is slidably connected to the corresponding adsorption rod 216 to achieve a seal between the rubber cover 215 and the adsorption rod 216. A wire mesh cover 221 is embedded in the side wall of the rubber cover 215. The wire mesh cover 221 is used to increase the deformation resistance of the rubber cover 215, thereby maintaining the negative pressure strength inside the adsorption rod 216 and achieving an effective adsorption and fixation effect.

[0050] Example 3: Please refer to Figures 1-8 As shown, the present invention also proposes a method of using a workpiece turning machine with a clamping mechanism, comprising the following steps:

[0051] Step 1: The conveyor belt 11 transports multiple parts at intervals until the parts are directly below the U-shaped frame 33. The camera 36 takes a picture of the current placement posture of the parts and sends the image information to the controller in the control panel 13. The controller first controls the piston rods of the two sets of cylinders 34 to move synchronously, pushing the corresponding clamping plates 35 to move, thereby clamping the parts. Then, it controls the servo motor 32 to deflect, thereby causing the clamped parts to deflect, unifying the placement posture of multiple parts on the conveyor belt 11, so that the two sets of U-shaped clamping plates 24 clamp the same two side walls of the parts.

[0052] Step 2: After the part moves with the conveyor belt 11 to the area between the two sets of U-shaped clamping plates 24, the controller in the control panel 13 activates the electric push rod 25. The electric push rod 25 pushes the mounting block 26 to move, and in conjunction with the connecting rod 27 hinged on both sides, pushes the two sets of movable rods 22 to tilt and slide relative to each other, causing the two sets of mounting frames 23 to move relative to each other while moving away from the fixed frame 21. With the help of the tension spring 212, the L-shaped clamping arm 211 is elastically rotated and connected to the mounting frame 23, so that the two sets of U-shaped clamping plates 24 can elastically clamp parts of different sizes to center them, and push the parts closer to the inner wall of the U-shaped conveyor table 1 on one side of the turning equipment 12.

[0053] Step 3: During the relative multi-directional movement of the two sets of ﹞-shaped clamping plates 24, the ﹞-shaped clamping plates 24 and the corresponding L-shaped clamping arms 211 are rotated to maintain multi-linear stable clamping of the parts. In addition, the mounting block 26 moves by carrying multiple abutment suction rods 216 through the abutment plate 214, causing the rubber sealing ring ends of the multiple abutment suction rods 216 to abut against one side of the parts, further assisting in pushing the parts to move. Then, combined with the U-shaped conveyor table 1 located on one side of the inner wall of the turning equipment 12, the parts are centrally and rigidly clamped. The turning equipment 12 is started by the controller to perform turning processing on the surface of the parts. Then, the electric push rod 25 carries the reset of the two sets of movable rods 22 and the rotation of the conveyor belt 11 to automatically load and unload the parts.

[0054] Step 4: During the movement of the contact plate 214, the hollow rod 218 and piston block 220 are simultaneously slid inside the corresponding sleeve 219. As the piston block 220 moves away from the fixed frame 21 inside the sleeve 219, the hollow rod 218, rubber cover 215, through port 217 and contact suction rod 216 draw in outside air until the rubber sealing ring end of the contact suction rod 216 touches the part. A negative pressure environment is formed in the area where the sleeve 219, hollow rod 218, rubber cover 215 and contact suction rod 216 are connected. As the piston block 220 moves, the negative pressure intensity is further increased. The part is first anti-sliply adsorbed and then rigidly clamped, which further stabilizes the position of the part during the turning process.

[0055] Step 5: After the adsorption rod 216 is stably adsorbed between itself and the part, the negative pressure intensity inside the rubber cover 215 is continuously increased by the movement of the piston block 220, causing the rubber cover 215 to shrink and deform. While maintaining the negative pressure state, it assists the part in smoothly contacting the inner wall of one side of the U-shaped conveyor table 1, thereby completing the multi-directional anti-deviation fixed clamping and completing the high-precision turning process of the part.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
