Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically to an automotive insert processing machine tool with a safe feeding mechanism. Background Technology

[0002] When a machine tool processes a blank, the blank to be processed needs to be clamped on a fixture by an operator so that the blank can move on the machine tool and come close to the processing tool for processing. Automotive inserts are installed on automobiles and require high precision. Processing with a machine tool can improve the processing efficiency and workpiece quality of automotive inserts, and ensure the reliability and durability of automotive inserts.

[0003] A search revealed a utility model patent with publication number CN219325035U, which discloses a CNC machine tool. The machine tool includes a protective housing and several air nozzles fixed to the top wall of the protective housing's inner cavity, facing the machine tool. Slag discharge ports are located at opposite ends of the bottom wall of the protective housing. By employing this technical solution, the air nozzles blow waste slag from the machine tool and the bottom wall of the protective housing to opposite sides of the bottom wall of the protective housing, where it is discharged through the slag discharge ports, thus preventing waste slag from affecting the normal operation of the machine tool.

[0004] Although the aforementioned patent uses air nozzles to blow the waste residue on the machine tool and the bottom wall of the protective box to the opposite sides of the bottom wall of the protective box and discharge it through the slag discharge port, thereby avoiding the waste residue from affecting the normal operation of the machine tool, with the increasing requirements of the automotive manufacturing industry for the precision, efficiency and safety of parts, traditional insert processing machine tools have problems such as low efficiency, poor precision and safety hazards in the feeding process, which makes it easy for inserts to fail the processing due to errors during the feeding process.

[0005] Therefore, it is necessary to propose an automotive insert processing machine tool with a safe feeding mechanism to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an automotive insert processing machine tool with a safe feeding mechanism. Through the cooperation between the internal parts of the protective mechanism, the accuracy between the movement of the blank on the machine tool body and the cutting tool can be judged. When the blank has not moved to the appropriate position, the cutting tool cannot start to process the blank, thereby improving the processing accuracy of the machine tool body on the blank and avoiding the safety hazards caused by tool collision. This solves the problems of low efficiency, poor accuracy and safety hazards in the feeding process of traditional insert processing machine tools in the prior art, which makes it easy for the insert to fail the processing due to errors during the feeding process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automotive insert processing machine tool with a safe feeding mechanism, comprising a machine tool body, wherein a processing mechanism is slidably connected to the right side of the machine tool body via an electric push rod and is located at the top of the machine tool body, and a protective mechanism is slidably connected to the surface of the processing mechanism and extends into the interior of the processing mechanism;

[0008] The processing mechanism includes a support plate, which is slidably connected to the top of the machine tool body and installed on the right side of the machine tool body via an electric push rod. A clamping assembly is bolted to the outer wall of the right side of the support plate. Multiple positioning posts are slidably connected around the outer wall of the clamping assembly, and the multiple positioning posts penetrate into the interior of the clamping assembly.

[0009] The protective mechanism includes a conical plate mechanically connected to the top and bottom of the outer wall of the positioning column and extending into the interior of the positioning column. A telescopic spring is mechanically connected between the bottom of the conical plate and the interior of the positioning column. A first photoelectric sensor is bolted to the outer wall of the support plate and distributed around the outer wall of the positioning column, located on one side of the conical plate. A limit slider is mechanically fixed to the outer wall of the positioning column extending into the interior of the support plate and slidably connected to the interior of the support plate. A support spring is mechanically connected between the positioning column and the interior of the support plate. A second photoelectric sensor is bolted to the interior of the support plate and located on one side of the positioning column.

[0010] Preferably, the machining mechanism further includes a control console, which is bolted to the top of the machine tool body and located on the right side of the support plate. A tool turntable is rotatably connected to the side of the control console near the support plate via a coupling, and multiple machining tools are mechanically rotated on the surface of the tool turntable.

[0011] Preferably, a control module is installed and fixed inside the control console and the machine tool body, and control buttons and a display screen are installed on the surface of the control console. The surface of the control console has multiple mating holes that match the positioning columns.

[0012] Preferably, the clamping assembly includes mechanical grippers and clamping slots that match the automotive inserts, and the clamping assembly is rotatably connected to the support plate via a coupling, and the machining heads on the surfaces of the plurality of machining tools are all different.

[0013] Preferably, the support plate has an internal telescopic groove that matches the positioning post, and the telescopic groove has an internal limiting groove that matches the limiting slider. The second photoelectric sensor and the first photoelectric sensor are connected to the control module via cables.

[0014] Preferably, the surface of the positioning post is provided with a shrinkage groove that matches the conical plate, and the surface of the conical plate is set as a conical surface, and the distance between the first photoelectric sensor and the conical plate is less than the distance between the positioning post and the second photoelectric sensor.

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

[0016] 1. By mounting and fixing the blank on the clamping assembly, and activating the electric push rod to push the support plate to slide on the machine tool body and approach the control console, the support plate moves and causes the positioning pins to engage with the mating holes on the surface of the control console. Multiple positioning pins pass through the mating holes. When the positioning pins contact the mating holes, the mating holes contact the tapered plates on the surface of the positioning pins and squeeze the tapered plates. The tapered plates are forced to compress the telescopic springs and move into the positioning pins, allowing the positioning pins to move into the mating holes. This improves the machining accuracy between the clamping assembly and the machining tools. At the same time, based on the blanks clamped and fixed on the clamping assembly, the tool turntable on the control console rotates, thereby completing the replacement of the machining tools. As the support plate continues to move, the positioning pins and the mating holes are subjected to mutual force. The positioning pins compress the support springs and move, causing the positioning pins to move inside the support plate and approach the second photoelectric sensor. After the second photoelectric sensor senses the signal, it transmits the signal to the control module, allowing the control module to control the machining tools to complete the machining operation of the blanks. This satisfies the machining needs of different blanks and improves the machining accuracy of the blanks.

[0017] 2. The support plate moves to engage the positioning column with the mating hole on the control panel surface. If the positioning column is not aligned with the mating hole, the support plate continues to move, causing the control panel surface to apply force to the positioning column. This force compresses the support spring, causing the positioning column to slide inside the support plate via the limit slider. Since the distance between the first photoelectric sensor and the tapered plate is less than the distance between the positioning column and the second photoelectric sensor, the tapered plate on the surface of the positioning column gradually approaches the first photoelectric sensor as it slides. The first photoelectric sensor senses the signal and transmits it to the control module, issuing a warning on the display screen on the machine tool body surface and stopping the electric push rod from moving the support plate. This avoids safety hazards such as the workpiece colliding with the machining tool due to continuous movement of the support plate, thus improving the safety of the support plate when feeding and processing the workpiece.

Detailed Implementation

[0027] 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.

[0028] This utility model provides, for example Figure 1-6 The illustrated automotive insert processing machine tool with a safety feeding mechanism includes a machine tool body 1. A processing mechanism 2 is slidably connected to the right side of the machine tool body 1 via an electric push rod and is located at the top of the machine tool body 1. A protective mechanism 3 is slidably connected to the surface of the processing mechanism 2 and extends into the interior of the processing mechanism 2.

[0029] The processing mechanism 2 includes a support plate 201, which is slidably connected to the top of the machine tool body 1 and installed on the right side of the machine tool body 1 by an electric push rod. A clamping assembly 202 is bolted to the outer wall of the right side of the support plate 201. Multiple positioning posts 203 are slidably connected around the outer wall of the clamping assembly 202, and the multiple positioning posts 203 penetrate into the interior of the clamping assembly 202.

[0030] The protective mechanism 3 includes a conical plate 301, which is mechanically connected to the top and bottom of the outer wall of the positioning post 203 and extends into the interior of the positioning post 203. A telescopic spring 302 is mechanically connected between the bottom of the conical plate 301 and the interior of the positioning post 203. A first photoelectric sensor 303 is bolted to the outer wall of the support plate 201 and is distributed around the outer wall of the positioning post 203 and located on one side of the conical plate 301. A limit slider 304 is mechanically fixed to the outer wall of the positioning post 203 that extends into the interior of the support plate 201 and is slidably connected to the interior of the support plate 201. A support spring 305 is mechanically connected between the positioning post 203 and the interior of the support plate 201. A second photoelectric sensor 306 is bolted to the interior of the support plate 201 and is located on one side of the positioning post 203.

[0031] By cooperating with each other among the internal parts of the machining mechanism 2, the blank can be clamped and fixed on the machine tool body 1, and the blank can be brought closer to the machining tool 206 on the machine tool body 1, thereby completing the machining operation of the blank. By cooperating with each other among the internal parts of the protective mechanism 3, the accuracy between the movement of the blank on the machine tool body 1 and the tool can be judged. When the blank has not moved to the appropriate position, the machining tool 206 cannot start to machine the blank, thereby improving the machining accuracy of the blank by the machine tool body 1 and avoiding the safety hazards caused by tool collision.

[0032] Refer to the instruction manual appendix Figure 1-6 The machining mechanism 2 also includes a control console 204, which is bolted to the top of the machine tool body 1 and located on the right side of the support plate 201. The side of the control console 204 closest to the support plate 201 is rotatably connected to a tool turntable 205 via a coupling. Multiple machining tools 206 are mechanically rotated on the surface of the tool turntable 205. Through the mutual cooperation between the internal parts of the machining mechanism 2, the tool turntable 205 can be rotated according to different blanks to change the machining tools 206.

[0033] Refer to the instruction manual appendix Figure 1-6 The control module is installed and fixed inside the control console 204 and the machine tool body 1. The control console 204 is equipped with control buttons and a display screen. The surface of the control console 204 has multiple mating holes that match the positioning pins 203. The multiple mating holes on the surface of the control console 204 that match the positioning pins 203 facilitate the positioning of the support plate 201 with the control console 204 through the positioning pins 203, thereby improving the docking accuracy between the blank and the machining tool 206.

[0034] Refer to the instruction manual appendix Figure 1-6The clamping assembly 202 includes mechanical jaws and clamping grooves that match the automotive inserts. The clamping assembly 202 is rotatably connected to the support plate 201 via a coupling. The machining heads on the surfaces of the multiple machining tools 206 are different. The clamping assembly 202, which includes mechanical jaws and clamping grooves that match the automotive inserts, and is rotatably connected to the support plate 201 via a coupling, facilitates the clamping assembly 202 in clamping and fixing the workpiece.

[0035] Refer to the instruction manual appendix Figure 1-6 The support plate 201 has an internal telescopic groove that matches the positioning column 203, and the telescopic groove has an internal limiting groove that matches the limiting slider 304. The second photoelectric sensor 306 and the first photoelectric sensor 303 are connected to the control module via cables. The second photoelectric sensor 306 and the first photoelectric sensor 303 are connected to the control module via cables, so that the second photoelectric sensor 306 and the first photoelectric sensor 303 can transmit the sensed signals to the control module. Thus, when the blank is not moved into place, the buttons on the surface of the machine tool body 1 cannot be started due to accidental touch.

[0036] Refer to the instruction manual appendix Figure 1-6 The surface of the positioning post 203 is provided with a shrinkage groove that matches the conical plate 301, and the surface of the conical plate 301 is set as a conical surface. The distance between the first photoelectric sensor 303 and the conical plate 301 is less than the distance between the positioning post 203 and the second photoelectric sensor 306. Because the distance between the first photoelectric sensor 303 and the conical plate 301 is less than the distance between the positioning post 203 and the second photoelectric sensor 306, it is convenient that when the docking hole on the surface of the positioning post 203 and the control console 204 cannot be docked, when the positioning post 203 is squeezed and shrinks, the conical plate 301 on the surface of the positioning post 203 will first locate the post 203 and be sensed by the first photoelectric sensor 303.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-6By mounting and fixing the workpiece onto the clamping assembly 202, and activating the electric push rod to push the support plate 201 to slide on the machine tool body 1 and approach the control console 204, the movement of the support plate 201 causes the positioning pins 203 to engage with the mating holes on the surface of the control console 204, allowing multiple positioning pins 203 to penetrate into the mating holes. When the positioning pins 203 contact the mating holes, the mating holes contact the tapered plate 301 on the surface of the positioning pins 203 and compress the tapered plate 301, causing the tapered plate 301 to compress the telescopic spring 302 and move into the positioning pins 203, allowing the positioning pins 203 to complete their movement into the mating holes, thereby improving the clamping assembly 202 and the machining tool 206. The machining accuracy is improved. At the same time, according to the blank clamped and fixed on the clamping assembly 202, the tool turntable 205 on the control console 204 rotates, thereby completing the replacement of the machining tool 206. When the support plate 201 continues to move, the positioning column 203 and the docking hole are subjected to mutual force. The positioning column 203 compresses the support spring 305 and moves, so that the positioning column 203 moves inside the support plate 201 and gets close to the second photoelectric sensor 306. After the second photoelectric sensor 306 senses the signal, it transmits the signal to the control module, so that the control module can control the machining tool 206 to work and complete the machining operation of the blank. This can meet the machining of different blanks and improve the machining accuracy of the blank.

[0039] Refer to the instruction manual appendix Figure 1-6 The support plate 201 moves, causing the positioning post 203 to engage with the mating hole on the surface of the control console 204. When the positioning post 203 is not aligned with the mating hole, the support plate 201 continues to move, causing the surface of the control console 204 to apply force to the positioning post 203. This force compresses the support spring 305, causing the positioning post 203 to slide within the support plate 201 via the limiting slider 304. The distance between the first photoelectric sensor 303 and the conical plate 301 is less than the distance between the positioning post 203 and the second photoelectric sensor. The distance between the devices 306 allows the tapered plate 301 on the surface of the positioning column 203 to gradually approach the first photoelectric sensor 303 as the positioning column 203 slides. This causes the first photoelectric sensor 303 to sense a signal and transmit it to the control module, which then issues a warning on the display screen on the surface of the machine tool body 1 and stops the electric push rod from moving the support plate 201. This avoids safety hazards such as the workpiece colliding with the machining tool 206 due to the continuous movement of the support plate 201, thereby improving the safety of the support plate 201 when it is feeding and processing the workpiece.

[0040] 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.
