DETAILED DESCRIPTION

[0033] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0034] Since existing gear blanks are currently processed by CNC machine tools, the processing efficiency is extremely low and the labor cost is high. Based on this, the present application provides a gear blank sawing machine tool that can improve the production efficiency of gear blanks. Among them, the so-called gear blank refers to a gear blank with coarse teeth processed using raw materials. The produced gear blank is then transferred to another finishing procedure, such as milling and other finishing processes, before the gear processing can be completed. Therefore, the processing efficiency of the gear blank directly affects the production efficiency of the gear.

[0035] Based on this, according to the first aspect of the present disclosure, Figure 1-6 As shown, the present application provides a gear blank sawing machine tool, including a base 1, a turntable 2 and a sawing device 3, the turntable 2 is rotatably installed in the base 1, the turntable 2 is used to install a workpiece (i.e., a raw material for the gear blank), and the sawing device 3 includes:

[0036] A power head device 4, the power head device 4 has a saw blade 41, and the saw blade 41 is used for sawing a workpiece;

[0037] The Z-direction feeding device 5 has a first output end, on which the power head device 4 is mounted, and the first output end is configured to be able to drive the power head device 4 to move back and forth along the Z axis in a straight line;

[0038] An angle adjustment device 6, on which the Z-direction feeding device 4 is mounted, and the angle adjustment device 6 is configured to be able to adjust the angle of the Z-direction feeding device 5 so as to adjust the sawing angle of the saw blade 41 in the power head device 4;

[0039] The X-direction moving device 7 has a second output end, on which the angle adjustment device 6 is installed, and the second output end is configured to synchronously drive the angle adjustment device 6, the Z-direction feeding device 5 and the power head device 4 to move back and forth along the X-axis in a straight line;

[0040] The Y-direction feeding device 8 has a third output end, on which the X-direction moving device 7 is installed. The third output end is configured to synchronously drive the X-direction moving device 7, the angle adjustment device 6, the Z-direction feeding device 5 and the power head device 4 to move back and forth in a straight line along the Y-axis.

[0041] For example, in the power head device 4, the gear box body is integrally cast with high-quality high-strength special materials, which has high strength and impact resistance. The transmission gear made of high-performance gear material undergoes special heat treatment and precision grinding, and a gear clearance elimination mechanism is used to achieve zero-gap transmission, ensuring smooth transmission and average service life of the saw blade, and high transmission efficiency. All bearings use imported high-precision and high-strength bearings, so that the entire gear box runs with low noise, stability, and reliable transmission performance. The optimized saw blade clamping system can greatly improve the rigidity of the circular saw blade, reduce the vibration and runout of the saw blade, thereby increasing the service life of the saw blade and ensuring the sawing accuracy. The power head device 4 in this application can be obtained commercially.

[0042] In this application, the directions shown by the X-axis, Y-axis and Z-axis are Figure 3 The direction indicated by the arrow.

[0043] For example, the power part of the Z-axis feeding device, the X-axis moving device, and the Y-axis feeding device is a linear guide mechanism, including but not limited to one or more combinations of ball screw linear guides, guide slide modules, roller linear guides, cylindrical linear guides, and ball linear guides. It only needs to be able to achieve reciprocating linear motion.

[0044] For example, the Z-direction feeding device 5 includes a Z-axis feeding base 51 and a first screw slider mechanism 52, and the first screw slider mechanism 52 includes a first servo motor 521, a first screw 522, a first nut seat 523, a first linear guide 524 and a first slider 525. The first linear guide 524 and the first servo motor 521 are installed on the Z-axis feeding base 51 along the Z-axis direction, the first slider 525 is slidably installed on the first linear guide 524 and can move linearly up and down along it, the first nut seat 523 is installed on the first screw 522, and the first servo motor 521 drives the first screw 522 to rotate so that the first nut seat 523 can move linearly back and forth along the first screw 522. The first nut seat 523 forms the first output end, and the first nut seat 523 and the first slider 525 are vertically installed with a mounting plate 42, and the power head device 4 is vertically installed on the mounting plate 42. The first output end is driven by the first servo motor 521 to synchronously drive the power head device 4 to move linearly back and forth along the Z axis.

[0045] The Z-axis feed base 51 is a column structure, composed of castings, with good rigidity and stability. The Z-axis feed base 51 can move in the Y-axis direction to determine the size of the sawing gear ring. The power head device 4 is installed on the vertical surface of the column through a linear guide rail and a screw slider mechanism. The first servo motor drives the high-precision screw to drive the power head device 4 to feed up and down, and quickly cut the clamped workpiece into a gear blank.

[0046] For example, the X-direction moving device 7 includes a second screw slider mechanism 72, which includes a second screw 721, a second nut seat 722 mounted on the second screw 721 and capable of linearly sliding back and forth along the second screw, a second fixed seat 725 for supporting the rotation of the second screw 721, a second linear guide 723, and a second slider 724 slidably mounted on the second linear guide 723 and capable of linearly moving back and forth along the second linear guide 723. The second slider 724 and / or the second nut seat 722 constitute the second output end, and the second support platform 71 is mounted on the second slider 724 and the second nut seat 722 (that is, the second output end is mounted on the second support platform 71), and the second support platform 71 is used to mount the angle adjustment device 6. Among them, the second fixed seat 725 and the second linear guide 723 are fixedly mounted on the third support platform 81 along the X-axis direction, so that the second output end synchronously drives the angle adjustment device 6 to linearly move back and forth along the X-axis direction, and the third support platform 81 is used to connect with the third output end of the Y-direction feeding device 8.

[0047] For example, the Y-direction feeding device 8 includes a third screw slider mechanism 82, which includes a third servo motor 821, a third screw 822, a third nut seat 823, a third linear guide 824 and a third slider 825. The third linear guide 824 and the third servo motor 821 are mounted on the base 83 along the Y-axis direction, the third slider 825 is slidably mounted on the third linear guide 824 and can move back and forth along the third linear guide, the third nut seat 823 is mounted on the third screw 822, and the third servo motor 821 drives the third screw 822 to rotate so that the third nut seat 823 can move back and forth along the third screw 822. The third nut seat 823 forms the third output end, and the third nut seat 823 and the third slider 825 are vertically mounted with a third support platform 81, and the third support platform 81 is mounted with an X-direction moving device 7. The third output end is driven by the third servo motor 821 to synchronously drive the X-direction moving device 7, the angle adjustment device 6, the Z-direction feeding device 5 and the power head device 4 to move back and forth in a straight line along the Y axis.

[0048] For example, the base 83 is a casting, which is a key component of the machine tool equipment. It has the characteristics of good overall rigidity, high strength, impact resistance, small deformation, and outstanding shock absorption performance. It can significantly improve the overall rigidity of the machine tool and the sawing stability and reliability of the machine tool.

[0049] The gear blank sawing machine tool of the present application can realize automatic feeding of the power head device in the Z-axis direction, the Y-axis direction and the X-axis direction by setting up a Z-direction feeding device 5, an X-direction moving device 7, and a Y-direction feeding device 8, and the Y-direction feeding device can adjust the distance between the power head device and the workpiece according to the required gear blank gear ring size, thereby improving the sawing efficiency. In addition, in the present application, by setting up an angle adjustment device 6, the sawing angle of the saw blade can be adaptively adjusted according to the gear blank gear rings of different sizes, which can meet the tooth shape requirements of different gear blanks, and the automation level of the machine tool is improved. Therefore, compared with traditional machine tools, the machine tool of the present application has a higher degree of automation, less operating time, can meet the needs of automated production, and has a wide range of applications in the field of gear blank sawing.

[0050] In the present application, the X-direction moving device 7 is provided because different gear blanks have different modules and different cutting points of different number of teeth. The power head device needs to move along the X-axis to minimize the machining allowance of the gear blank after sawing. The X-direction moving device 7 can be manually operated or electrically operated.

[0051] In this application, by setting up the Y-direction feeding device 8, it can meet the requirements of sawing of gear blanks and gear rings in the diameter range of 4500-8000mm. Therefore, the power head device 4 needs to move along the Y axis, and the movement is guided by a linear guide rail. It is driven by a servo motor to move to a set position and lock before starting sawing. It can meet the requirements of sawing gear blanks in a large diameter range.

[0052] In one embodiment, Figure 3-6 As shown, the angle adjustment device 6 includes a rotating support 61, which can be a bearing. The fixed portion 611 of the rotating support 61 (when the rotating support is a bearing, the fixed portion 611 refers to the inner ring of the bearing) is connected to the second output end through the second support platform 71, and the rotating portion 612 of the rotating support 61 (when the rotating support is a bearing, the rotating portion 612 refers to the outer ring of the bearing) is connected to the Z-direction feeding device 5 through the first support platform 53, so that the first support platform 53 synchronously drives the Z-direction feeding device 5 to rotate around the second support platform 71 to a specified angle.

[0053] Specifically, the first support platform 53 is fixedly connected to the bottom surface of the Z-axis feeding base 51 of the Z-axis feeding device 5 , and the first support platform 53 serves to connect the angle adjustment device 6 and the Z-axis feeding device 5 .

[0054] For example, the angle adjustment device 6 also includes a first locking device 62, which is connected to the first support platform 53 and the second support platform 71. The first locking device 62 is configured to lock the first support platform 53 so that the first support platform 53 is locked at the specified angle when the first support platform 53 synchronously drives the Z-axis feeding device 5 to rotate around the second support platform 71 to a specified angle.

[0055] Specifically, the first locking device 62 includes a first locking mechanism 621 and a first guide rail assembly 622, the first locking mechanism 621 has a retractable first locking end 6211; the first guide rail assembly 622 includes two first guide rails 6221 spaced apart and the first guide rails 6221 are installed on the second support platform 71, the fixed end of the first locking mechanism 621 is installed on the first support platform 53, the first locking end 6211 is accommodated between the two first guide rails 6221, and the first locking end 6211 is configured to be able to move synchronously with the first support platform 53 to a specified angle and shrink inwardly and press against the first guide rail 6221.

[0056] For example, the first locking mechanism 621 may be a cylinder having a retractable end. Figure 3-6 As shown, the first guide rail 6221 is installed on the second support platform 71 in an arc shape, and a first accommodating cavity 623 for the first locking end 6211 to move freely is formed between the two first guide rails 6221, and the opening of the first accommodating cavity 623 is smaller than the diameter of the end of the first locking end 6211, so that the first locking end 6211 is confined in the first accommodating cavity 623. Therefore, when the first support platform 53 drives the fixed end of the first locking mechanism 621 to rotate to a certain angle, during this process, the first locking end 6211 can automatically follow the movement in the first accommodating cavity 623 and does not interfere with the first guide rail 6221. When the first support platform 53 rotates to a set angle, the first locking end 6211 shrinks and presses against the first guide rail 6221, so that the first support platform 53 and the second support platform 71 are locked and fixed to each other.

[0057] Furthermore, the angle adjustment device 6 also includes an angle ruler 63, which is arranged on the first guide rail assembly 622 to indicate the rotation angle of the first support platform 53. Specifically, the measuring range of the angle ruler 63 is generally between 15 and 45 degrees, the indicator needle of the angle ruler 63 is installed on the first support platform 53, and the main body of the angle ruler is installed on the outer surface of the first guide rail 6221. When the first support platform 53 rotates, the rotation angle of the first support platform 53 can be determined by the angle indicated by the indicator needle.

[0058] In the present application, the angle adjustment device 6 can be provided to meet the requirements of gear blanks and gear rings of different sizes and the tooth shape requirements of different gear blanks.

[0059] This is because the module and outer diameter of the gear ring are inconsistent, and the size of the tooth blank is also different. In order to meet the sawing of different teeth and reduce the milling processing allowance, the Z-axis feed base 51 needs to be adjusted at a small angle with the power head device. Since the lower part of the Z-axis feed base 51 adopts a rotating support, the angle adjustment is manual. After replacing gear rings of different sizes, the rear saw blade angle is manually adjusted to meet the sawing requirements and manually locked.

[0060] For example, further, in order to facilitate the rotation of the first support platform 53, the angle adjustment auxiliary component 64 can be used for auxiliary adjustment. Specifically, the angle adjustment auxiliary component 64 includes an adjustment rod 641, the first end of which is rotatably connected to the first support platform 53 through a connecting seat 642, and the first end of the adjustment rod 641 is installed in the connecting seat 642 through a bearing, so that the adjustment rod 641 can rotate around the connecting seat 642, and the first support platform 53 is driven to rotate to a set angle by manually pushing the adjustment rod 641. Of course, the angle adjustment auxiliary component 64 may not be provided. As long as the first support platform 53 can be driven to rotate.

[0061] In one embodiment, the tooth blank sawing machine tool of the present application further includes a second locking device 73 and a third support platform 81, wherein the third support platform 81 is installed on the third output end and an X-direction moving device is installed on the third support platform. The second locking device 73 is installed between the second support platform 71 and the third support platform 81, and the second locking device 73 is configured to lock the second support platform 71 when the second support platform 71 synchronously drives the angle adjustment device 6, the Z-direction feeding device 5 and the power head device 4 to move to the specified position along the X-axis straight line, so that the second support platform 71 is locked in the specified position.

[0062] Specifically, the second locking device 73 includes a second locking mechanism 731 and a second guide rail assembly 732, the second locking mechanism 731 has a retractable second locking end 7311; the second guide rail assembly 732 includes two second guide rails 7321 arranged at intervals and the two second guide rails 7321 are installed on the third support platform 81 along the X-axis direction, the fixed end of the second locking mechanism 731 is installed on the second support platform 71, the second locking end 7311 is accommodated between the two second guide rails 7321, and the second locking end 7311 is configured to be able to move synchronously with the second support platform 71 to a specified position and shrink inwardly to press against the second guide rail 7321. For example, the second locking mechanism 731 can be a cylinder having a retractable end.

[0063] The second guide rail 7321 is installed on the third support platform 81 in a straight line along the X-axis direction, and a second accommodating cavity 733 for the second locking end 7311 to move freely is formed between the two second guide rails 7321, and the opening of the second accommodating cavity is smaller than the diameter of the second locking end, so that the second locking end is confined in the second accommodating cavity. Therefore, when the second support platform 71 moves to a specified position along the X-axis, during this process, the second locking end 7311 can automatically follow the movement and does not interfere with the second guide rail. When the second support platform 71 moves to the specified position, the second locking end 7311 retracts and presses against the second guide rail 7321, thereby locking and fixing the second support platform and the third support platform to each other.

[0064] In one embodiment, Figure 3-6 As shown, the present application also includes a third locking device 84 and a base 83. The third locking device 84 is installed between the third support platform 81 and the base 83. The third locking device 84 is configured to lock the third support platform 81 so that the third support platform is locked in the specified position when the third support platform 81 synchronously drives the X-axis moving device, the angle adjustment device, the Z-axis feeding device and the power head device to move to the specified position along the Y-axis straight line.

[0065] Specifically, the third locking device 84 includes a third locking mechanism 841 and a third guide rail assembly 842, wherein the third guide rail assembly 842 includes two third guide rails 8421 arranged at intervals and the two third guide rails 8421 are installed on the base 83; the third locking mechanism 841 has a retractable third locking end 8411, the fixed end of the third locking mechanism 841 is installed on the third support platform 81, the third locking end 8411 is accommodated between the two third guide rails 8421, and the third locking end 8411 is configured to be able to follow the third support platform to move to a specified position along the Y-axis straight line and shrink inwardly to press against the third guide rail. The third locking mechanism can be a cylinder with a retractable end.

[0066] The third guide rail 8421 is linearly installed on the base 83 along the Y-axis direction, and a third accommodating cavity 843 for the third locking end 8411 to move freely is formed between the two third guide rails 8421, and the opening of the third accommodating cavity 843 is smaller than the end diameter of the third locking end 8411, so that the third locking end 8411 is restricted in the third accommodating cavity 843. Therefore, when the third support platform moves to a specified position along the Y-axis straight line, during this process, the third locking end 8411 can automatically follow the movement in the third accommodating cavity and does not interfere with the third guide rail 8421, until the third support platform 81 moves to the specified position, the third locking end 8411 retracts and presses on the third guide rail 8421, so that the third support platform 81 and the base 83 are locked and fixed to each other.

[0067] For example, a foldable bellows cover 85 is provided on the base 83, and the bellows cover 85 is used to cover the slide rails, blocks, etc. in the Y-direction feeding device to prevent the debris generated by sawing from falling and affecting the operation of the machine tool. And one end of the bellows cover 85 is connected to the third support platform, so that when the third output end drives the third support platform to move linearly along the Y axis, the bellows cover 85 can be compressed or stretched as the third output end moves.

[0068] In one embodiment, Figure 3-6 As shown, the tooth blank sawing machine tool of the present application also includes a chip removal device 9 and a debris collection device 91. The chip removal device 9 is installed in front of the power head device and is connected to the third support platform 81, and is used to collect the debris generated when the workpiece is sawed and output the debris to the debris collection device 91. By setting up a chip removal device, the present application can collect the sawing debris in real time to protect the normal operation of the machine tool.

[0069] Of course, considering the inconsistent sizes of the gear rings, the output position of the sawdust is also variable, so the chip removal device needs to be placed according to the specific position, so the chip removal device adopts a flexible layout.

[0070] For example, the gear blank sawing machine tool of the present application also includes a cooling system, and the machine tool cooling adopts cooling water circulation to cool the workpiece. The gear blank sawing machine tool of the present application also includes a control system, and the control part is composed of an electrical cabinet, a touch screen, buttons, a PLC, a motor, a contactor, a relay, a switch and auxiliary components. Since the sawing part is a part of the equipment that completes the entire gear ring processing equipment, the sawing part equipment has its own control system, and shares and calls information with other equipment to realize the sawing processing of the gear ring (i.e., the gear blank). The control system controls the operation of the entire machine tool. The control system is electrically connected to the Z-direction feeding device, the Y-direction feeding device, the first locking mechanism, the second locking mechanism, the third locking mechanism and the power head device respectively to control their work. The control system can be implemented using existing technology and will not be repeated here.

[0071] The working process of the gear blank sawing machine tool of the present application is described in detail below:

[0072] 1) Using a crane to move the raw material (i.e., the workpiece) onto the turntable 2, so that the turntable 2 can drive the workpiece to rotate;

[0073] 2) manually adjusting the X-direction moving device so that the second support table synchronously drives the angle adjustment device, the Z-direction feeding device and the power head device thereon to move along the X-axis direction until the power head device is located at a specified position, and adjusting the rotating support so that the Z-direction feeding device and the power head device on the first support table rotate synchronously, thereby adjusting the rotation angle of the power head device;

[0074] 3) Determine the Y-axis cutting point and the Z-axis entry point and penetration point for tool setting;

[0075] 4) Start the machine tool, the first locking device and the second locking device are both in a locked state, that is, the first support platform, the second support platform and the third support platform are locked with each other, and the third output end synchronously drives the third support platform to move along the Y axis to the cutting point;

[0076] 5) The saw blade on the power head device rotates to start cutting, and the saw blade of the power head device moves from bottom to top along the Z axis until it reaches the cutting point;

[0077] 6) The power head device moves downward along the Z axis to the origin, and one tooth sawing is completed;

[0078] 7) The turntable rotates;

[0079] 8) The next cycle starts until all the sawing teeth are completed;

[0080] 9) The third support platform and the power head device return to the origin respectively.
