Description

Technical Field

[0001] This invention relates to the field of machine tool technology, and in particular to a multi-position synchronous machining machine tool. Background Technology

[0002] Machine tools are machines used to manufacture machinery and equipment. After more than 100 years of development, machine tools have become the "mother machines" of the machinery industry, playing a vital role in the modernization of the national economy. Conventional machine tools are usually equipped with a turret and a chuck. The chuck can hold the workpiece, while the turret can change tools according to processing requirements, machining the desired shape on the workpiece.

[0003] Common machine tools typically have a turret to process different positions one by one, thus satisfying the processing needs of different positions. During the processing, the position of the turret is adjusted to meet the processing requirements. However, when it is necessary to process workpieces in multiple positions, this processing method is relatively inefficient and can easily affect the overall production efficiency. Summary of the Invention

[0004] To address the issue that conventional machining methods are relatively inefficient and can negatively impact overall production efficiency when processing workpieces in multiple positions under existing technologies, this application provides a multi-position synchronous machining tool, the specific solution of which is as follows.

[0005] A multi-position synchronous machining machine tool includes a machine tool body, characterized in that: a clamping assembly and a machining assembly are provided on the machine tool body, the clamping assembly is used to clamp a workpiece, and the machining assembly includes a first turret and a second turret, both of which are movably connected to the machine tool body, the first turret and the second turret are located on one side of the length direction of the clamping assembly, the first turret and the second turret are movable along the machine tool body, and both the first turret and the second turret are capable of mounting cutting tools and machining workpieces; The machining assembly also includes a third turret, which is located on one side of the clamping assembly along its length. The third turret is located on the opposite side of the first and second turrets, and tools can also be mounted on the third turret for machining workpieces.

[0006] By adopting the above technical solutions, the machine tool can use the first turret, the second turret, and the third turret to process the workpiece from different sides, realize multi-position synchronous processing, improve processing efficiency, and each turret can move along the machine tool body, so that the processing position can be flexibly adjusted.

[0007] Optionally, the table of the machine tool body is inclined, the first turret and the second turret are set higher than the clamping assembly, and the clamping assembly is set higher than the third turret.

[0008] By adopting the above technical solution, the machine tool body table is tilted, with the first and second turrets higher than the clamping assembly, and the clamping assembly higher than the third turret. This facilitates chip removal, avoids chip accumulation during processing that affects machining accuracy and equipment operation, and also makes the layout of each turret and clamping assembly reasonable, which is conducive to each component independently and efficiently performing machining operations on the workpiece.

[0009] Optionally, the clamping assembly includes a first chuck and a second chuck, which are respectively disposed at both ends of the machine tool body. The first chuck and the second chuck are used to clamp the two ends of the workpiece and can drive the workpiece to rotate. Both the first chuck and the second chuck are provided with clamping slots. The clamping slot of the first chuck is through-hole, and the workpiece can extend from the end of the first chuck into the first chuck and into the clamping slot of the second chuck.

[0010] By adopting the above technical solution, the first chuck and the second chuck are respectively set to clamp the two ends of the workpiece and drive them to rotate, so that the workpiece can rotate stably for processing. Especially when it is necessary to process products from multiple positions at the same time, clamping from both ends can further maintain the stability of the workpiece. The clamping slot of the first chuck is set through, which makes it convenient for the workpiece to extend from the end of the first chuck and enter the clamping slot of the second chuck, so as to realize the smooth clamping of the workpiece.

[0011] Optionally, a buffer element is provided in the clamping groove of the second chuck. The buffer element is slidably connected to the second chuck. A buffer spring is provided between the buffer element and the inner wall of the second chuck. One end of the buffer spring is fixedly connected to the inner wall of the second chuck, and the other end of the buffer spring is fixedly connected to the buffer element. The buffer spring has a tendency to push the buffer element toward the first chuck.

[0012] By adopting the above technical solution, a buffer and a buffer spring are set in the clamping groove of the second chuck. The buffer spring pushes the buffer to move towards the first chuck, which can buffer the workpiece and reduce the damage caused by the impact of the workpiece on the second chuck when it is fed. In addition, since multiple turrets are used for processing at the same time, the buffer and the buffer spring can effectively buffer some of the vibration, avoid damage to the workpiece, and further improve product quality.

[0013] Optionally, the second chuck is further provided with a shock absorber. The shock absorber is arranged at equal intervals around the clamping groove. A shock absorber spring is provided between the shock absorber and the second chuck. The shock absorber spring is fixedly connected to the shock absorber and can push the shock absorber to move toward the workpiece.

[0014] By adopting the above technical solution, vibration damping components are equidistantly arranged around the clamping groove in the second chuck, and vibration damping springs are arranged between the vibration damping components and the second chuck. The vibration damping springs push the vibration damping components toward the workpiece, which can further reduce the vibration of the workpiece during processing. Especially when multiple turrets are processing simultaneously, the processing accuracy can be further improved.

[0015] Optionally, the shock absorber is provided with a shock-absorbing wheel, which is rotatably connected to the shock absorber and can abut against the workpiece.

[0016] By adopting the above technical solution, the shock absorber is equipped with a rotating shock absorber wheel that abuts against the workpiece, which can reduce the friction between the shock absorber and the workpiece, making the shock absorption process smoother, and avoiding wear when feeding raw materials.

[0017] Optionally, the shock absorber is positioned close to the buffer, and when the side wall of the workpiece abuts against the buffer, the end of the workpiece abuts against the buffer.

[0018] By adopting the above technical solution, the shock absorber is set close to the buffer, so that the side wall and end of the workpiece abut against the buffer at the same time. They can work together to fix and dampen the workpiece, better stabilize the workpiece, and improve the processing accuracy.

[0019] Optionally, a feed rack is provided at the first chuck, and the feed rack has a feed groove for placing workpieces, and the feed groove is connected to the clamping groove of the first chuck.

[0020] By adopting the above technical solution, a feeding rack is set at the first chuck. The feeding rack has a feeding groove that is connected to the clamping groove of the first chuck. This makes it easier to put the workpiece into the feeding groove and then directly into the clamping groove of the first chuck, thereby improving the convenience of feeding and increasing processing efficiency.

[0021] Optionally, a feeding drive is provided in the feeding trough, and the feeding starter can push the workpiece to move along the feeding trough.

[0022] By adopting the above technical solution and setting a feeding drive component in the feeding groove, the workpiece can be pushed to move along the feeding groove, realizing automatic feeding of the workpiece and improving processing efficiency.

[0023] Optionally, the feeding drive component is provided with a rubber pad, which is used to abut against the workpiece.

[0024] By adopting the above technical solution, the rubber pad on the feeding drive can increase friction when pushing the workpiece, thus avoiding damage to the workpiece. At the same time, when the workpiece is released after processing, the presence of the spring may cause impact to the workpiece. The rubber pad can provide protection and reduce the possibility of workpiece damage.

[0025] In summary, this application has at least the following beneficial effects: This application addresses the problem that conventional processing methods are relatively inefficient and can easily affect overall production efficiency when processing workpieces in multiple positions under existing technology. This application solves the problem by setting up three turrets to process the workpiece simultaneously, processing three positions at a time, which can effectively increase processing efficiency.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A multi-position synchronous machining tool, such as Figure 1 and Figure 2 As shown, the machine tool includes a machine tool body 1, on which a clamping assembly 2 and a machining assembly 3 are mounted. The clamping assembly 2 is used to clamp workpieces. The machining assembly 3 includes a first turret 31 and a second turret 32, both of which are movably connected to the machine tool body 1. The first turret 31 and the second turret 32 ​​are located on one side of the length direction of the clamping assembly 2 and can move along the machine tool body 1. Both the first turret 31 and the second turret 32 ​​can mount cutting tools and machine workpieces. The machining assembly 3 also includes a third turret 33, which is located on one side of the length direction of the clamping assembly 2 and on the opposite side of the first turret 31 and the second turret 32. The third turret 33 can also mount cutting tools and machine workpieces. In practice, the first turret 31, the second turret 32, and the third turret 33 all use conventional turrets and require corresponding programs for control. Matching tools need to be installed on the turrets, and the corresponding tools need to be changed to accurately process the workpiece. Under program control, the three turrets can process synchronously.

[0031] like Figure 1As shown, the table of the machine tool body 1 is inclined, with the first turret 31 and the second turret 32 ​​positioned higher than the clamping assembly 2, and the clamping assembly 2 positioned higher than the third turret 33. In practice, the inclined arrangement allows the machined chips to be discharged along the inclined surface, making chip discharge more convenient.

[0032] like Figure 1 and Figure 2 As shown, the clamping assembly 2 includes a first chuck 21 and a second chuck 22. The first chuck 21 and the second chuck 22 are respectively disposed at both ends of the machine tool body 1. The first chuck 21 and the second chuck 22 are used to clamp the two ends of the workpiece and can drive the workpiece to rotate. Both the first chuck 21 and the second chuck 22 are provided with clamping grooves. The clamping groove of the first chuck 21 is through-hole, and the workpiece can extend from the end of the first chuck 21 into the first chuck 21 and into the clamping groove of the second chuck 22. In practice, when clamping the workpiece, it only needs to pass through the first chuck 21 and then into the second chuck 22. The first chuck 21 and the second chuck 22 then clamp the workpiece, and the first chuck 21 and the second chuck 22 can then drive the workpiece to rotate. The first chuck 21 and the second chuck 22 can be common pneumatic chucks, and can also be driven to rotate by gear transmission. The first chuck 21 can be driven by a motor as a power source to transmit power to the gears. The second chuck 22 is also rotatable. The second chuck 22 can rotate with the first chuck 21, or it can be actively driven by a motor, but the first chuck 21 and the second chuck 22 should rotate synchronously.

[0033] like Figure 1 and Figure 2 As shown, a buffer element 221 is provided in the clamping groove of the second chuck 22. The buffer element 221 is slidably connected to the second chuck 22. A buffer spring 222 is provided between the buffer element 221 and the inner wall of the second chuck 22. One end of the buffer spring 222 is fixedly connected to the inner wall of the second chuck 22, and the other end is fixedly connected to the buffer element 221. The buffer spring 222 has a tendency to push the buffer element 221 toward the first chuck 21. In specific implementation, when the workpiece is fed in, it will come into contact with the buffer element 221. To avoid damage to the workpiece caused by collisions during feeding, a rubber pad or similar material can be provided on the buffer element 221 to further improve the protection of the workpiece. During unloading, the buffer element 221 can also provide a certain auxiliary unloading effect, further improving the convenience of processing.

[0034] like Figure 1 and Figure 2As shown, the second chuck 22 is also equipped with a shock absorber 223, which is equidistantly spaced around the clamping groove. A shock absorber spring 224 is provided between the shock absorber 223 and the second chuck 22, and is fixedly connected to the shock absorber 223. The shock absorber spring 224 can push the shock absorber 223 toward the workpiece. A shock absorber wheel 225 is provided on the shock absorber 223, and is rotatably connected to the shock absorber 223. The shock absorber wheel 225 can abut against the workpiece. The shock absorber 223 is located near the buffer member 221. When the side wall of the workpiece abuts against the buffer member 221, the end of the workpiece abuts against the buffer member 221. In practice, when the workpiece is fed in, it can be fed in under the guidance of the shock-absorbing wheel 225 to avoid the situation where it cannot be fed in due to interference. Then, with the cooperation of the shock absorber 223 and the buffer 221, the end of the workpiece is fixed and then processed. During processing, since multiple turrets process the workpiece at the same time, the stress inside the workpiece is relatively large. Therefore, by releasing the shock absorber 223 and the buffer 221, the damage to the workpiece during processing can be effectively reduced, and the yield rate can be further improved.

[0035] like Figure 1 and Figure 2 As shown, a feed rack 211 is provided at the first chuck 21, and a feed groove 212 for placing workpieces is opened on the feed rack 211. The feed groove 212 is connected to the clamping groove of the first chuck 21. A feed drive component 213 is provided in the feed groove 212, which can push the workpiece to move along the feed groove 212. A rubber pad 214 is provided on the feed drive component 213, which is used to abut against the workpiece. In specific implementation, the feed drive component 213 consists of multiple rotatable drive wheels, which are driven by a motor to rotate. By contacting the workpiece, they drive the workpiece to move. Since the reaction force of the spring will push the workpiece in the opposite direction when feeding and unloading, the feed drive component 213 is required to push the workpiece and also needs to protect the workpiece to a certain extent.

[0036] Working principle: Multiple turrets are set up to process the workpiece simultaneously, completing multiple processing steps in one go. In order to avoid the problem of workpiece damage caused by simultaneous multi-step processing, multiple chucks are also set up for clamping, and shock-absorbing buffer 221 is set up to prevent workpiece damage.

[0037] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
