Description

Technical Field

[0001] This utility model relates to the field of bolt ball processing technology, and more specifically to a cutting device for bolt balls used in space frame structures. Background Technology

[0002] A bolt ball is a mechanical connecting element commonly used in steel structure space frames as a component connecting members and nodes. The structure of a bolt ball typically includes a spherical body with a hole in the center for inserting a bolt. The two ends of the bolt are fixed to the sphere and the connecting member, respectively.

[0003] In the machining process of bolt balls, a cutting device is needed to machine a flat surface on the surface of the bolt ball, and then drill holes and machine threads on the flat surface. In the existing technology, the above operations are mainly carried out with the help of machine tools as cutting devices.

[0004] However, the following problems can easily occur when using machine tools for cutting:

[0005] During the processing, the bolt ball needs to be machined into a flat surface first, then a hole needs to be drilled in the flat surface, and finally the thread needs to be machined in the hole. If the above three steps are carried out on one machine tool, the tool needs to be changed three times on the machine tool. If each step is assigned to a separate machine tool, three machine tools are needed, which is undoubtedly very cumbersome and will greatly reduce the processing efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cutting device for bolt balls for space frame structures to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: a cutting device for bolt balls in a space frame structure, including a machine tool, and further including: a tool changer, a drive assembly, and a fixing assembly. The tool changer is rotatably and slidably mounted on the machine tool. The fixing assembly is mounted on the tool changer, and the machining tool is connected to the tool changer through the fixing assembly. When the tool changer rotates, the machining tool connected to the tool changer through the fixing assembly can be aligned with the machine tool spindle. At the same time, there are more than three positions on the fixing assembly where machining tools can be installed. The fixing assembly is equipped with a transmission assembly, and the transmission assembly realizes the transmission between the machine tool spindle and the machining tool. The drive assembly is fixedly mounted on the machine tool and can drive the tool changer to rotate and slide.

[0008] Furthermore, the fixing component includes a mounting hole and a connecting shaft. The mounting hole is opened on the tool changer, and when the tool changer rotates, the mounting hole can be coaxial with the machine tool spindle. The end of the connecting shaft is provided with an insertion hole, and the mounting end of the machining tool can be inserted into the insertion hole and rotate synchronously with the connecting shaft.

[0009] Furthermore, a set screw is installed in the middle thread of the connecting shaft, and when the set screw is tightened, the mounting end of the machining tool remains fixed to the connecting shaft. A limit component is installed between the tool changer and the connecting shaft to limit the axial position of the connecting shaft.

[0010] Furthermore, the limiting component includes a limiting ring groove and a limiting half-ring. The limiting ring groove is formed on the surface of the connecting shaft, the inner ring of the limiting half-ring can be locked in the limiting ring groove, and the limiting half-ring is fixed to the side of the tool changer by bolts.

[0011] Furthermore, there are two sets of limiting semi-rings, which are distributed on both sides of the tool changer, and each set of limiting semi-rings has two rings.

[0012] Furthermore, the transmission assembly includes a first transmission shaft and a first transmission sleeve. The first transmission shaft is fixedly installed at the end of the connecting shaft away from the insertion hole.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0024] Figure 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1-4 The present invention will be further described below.

[0025] A cutting device for bolt balls in a space frame structure includes a machine tool 1, and further includes a tool changer 2, a drive assembly, and a fixing assembly. The tool changer 2 is rotatably and slidably mounted on the machine tool 1. The fixing assembly is mounted on the tool changer 2, and the machining tool is connected to the tool changer 2 through the fixing assembly. When the tool changer 2 rotates, the machining tool connected to the tool changer 2 through the fixing assembly can be aligned with the spindle of the machine tool 1. At the same time, there are more than three positions on the fixing assembly where machining tools can be installed. The fixing assembly is equipped with a transmission assembly, and the transmission assembly realizes the transmission between the spindle of the machine tool 1 and the machining tool. The drive assembly is fixedly mounted on the machine tool 1, and the tool changer 2 can be driven to rotate and slide through the drive assembly.

[0026] In use, machining tools such as cutting tools, taps, and drills are connected to the tool changer 2 via a fixing assembly. Then, the bolt ball to be machined is installed on the worktable. At this time, according to the machining requirements, the drive assembly is activated to drive the tool changer 2 to rotate, so that the required machining tool is aligned with the bolt ball. The tool changer 2 is then slid through the drive assembly, so that it is connected to the spindle of the machine tool 1 through the transmission assembly. In this way, after the machine tool 1 is started, it can drive the machining tool to move to machine the bolt ball. When it is necessary to switch machining tools, simply disconnect the transmission between the tool changer 2 and the spindle of the machine tool 1, and rotate the tool changer 2 to switch to other machining tools.

[0027] The fixing assembly includes a mounting hole 3 and a connecting shaft 4. The connecting shaft 4 is rotatably mounted in the mounting hole 3. The mounting hole 3 is opened on the tool changer 2, and when the tool changer 2 rotates, the mounting hole 3 can be coaxial with the spindle of the machine tool 1. The end of the connecting shaft 4 is provided with an insertion hole 5. The mounting end of the machining tool can be inserted into the insertion hole 5 and rotate synchronously with the connecting shaft 4. In this way, the installation of the machining tool and the tool changer 2 can be completed by simply inserting the mounting ends of machining tools such as lathe tools, taps and drills into the insertion holes 5 at the ends of the connecting shafts 4 respectively.

[0028] The connecting shaft 4 has a set screw 6 installed in the middle thread. When the set screw 6 is tightened, the mounting end of the machining tool is fixed to the connecting shaft 4. Thus, tightening the set screw 6 is sufficient to fix the mounting end of the machining tool to the connecting shaft 4.

[0029] A limiting component is installed between the tool changer 2 and the connecting shaft 4 to limit the axial position of the connecting shaft 4. The limiting component includes a limiting ring groove 7 and a limiting half-ring 8. The limiting ring groove 7 is formed on the surface of the connecting shaft 4. The inner ring of the limiting half-ring 8 can be engaged in the limiting ring groove 7, and the limiting half-ring 8 is fixed to the side of the tool changer 2 by bolts. Thus, by simply engaging the inner ring of the limiting half-ring 8 with the limiting ring groove 7 and fixing the limiting half-ring 8 to the tool changer 2 with bolts, the limiting of the connecting shaft 4 and the tool changer 2 can be achieved. There are two sets of limiting half-rings 8, which are distributed on both sides of the tool changer 2. Each set of limiting half-rings 8 has two, so the two limiting half-rings 8 can provide a more comprehensive limitation of the connecting shaft 4.

[0030] The transmission assembly includes a first transmission shaft 9 and a first transmission sleeve 10. The first transmission shaft 9 is fixedly installed at the end of the connecting shaft 4 away from the insertion hole 5. The first transmission sleeve 10 is coaxially connected to the spindle of the machine tool 1, and the first transmission shaft 9 can be slidably inserted into the first transmission sleeve 10 and rotate synchronously with the first transmission sleeve 10. Thus, when the connecting shaft 4 corresponds to the spindle of the machine tool 1, the tool changer 2 only needs to slide along its axis to drive the first transmission shaft 9 to be inserted into the end of the first transmission sleeve 10. In this way, the machine tool 1 will drive the machining tool to rotate when it is started.

[0031] The drive assembly includes a motor 11, a cylinder 12, a connecting rod 13, a second transmission shaft 14, and a second transmission sleeve 15. The motor 11 is fixedly mounted on the machine tool 1. The second transmission sleeve 15 is coaxially connected to the output shaft of the motor 11. One end of the second transmission shaft 14 is slidably inserted into the second transmission sleeve 15 and can rotate synchronously with the second transmission sleeve 15. The other end is coaxially connected to the shaft of the tool changer 2. The connecting rod 13 is rotatably sleeved on the second transmission shaft 14 and can drive the second transmission shaft 14 to slide synchronously. The cylinder 12 is fixedly mounted on the machine tool 1, and the movable end of the cylinder 12 is fixedly connected to the connecting rod 13. Thus, by simply starting the motor 11, the motor 11 will drive the second transmission sleeve 15 to rotate, thereby driving the second transmission shaft 14 to rotate, and then driving the tool changer 2 to rotate. Activating the cylinder 12 will retract the movable end of the cylinder 12, which will then drive the tool changer 2 to move along its axis.

[0032] There are two sets of cylinders 12, which operate synchronously. The two sets of cylinders 12 are symmetrically distributed on both sides of the motor 11, thereby ensuring the stability of the movement of the tool changer 2.

[0033] Therefore, the complete usage process is as follows: First, insert the mounting ends of machining tools such as lathe tools, taps, and drills into the insertion holes 5 at the ends of each connecting shaft 4, and tighten the set screws 6 to fix them. Then, insert the connecting shaft 4 into the mounting hole 3, and then engage the inner ring of the limiting half-ring 8 with the limiting ring groove 7. Use bolts to fix the limiting half-ring 8 to the tool changing wheel 2 to achieve the limiting of the connecting shaft 4 and the tool changing wheel 2. At this time, the bolt ball to be machined can be installed on the worktable. At the same time, start the motor 11. The motor 11 will drive the second transmission sleeve 15 to rotate, thereby driving the second transmission shaft 14 to rotate, and then driving the tool changing wheel 2 to rotate, until the tool changing wheel 2 rotates to the desired position. When the cutting tool is rotated to align with the position of the bolt ball, the first drive shaft 9 will align with the position of the first drive sleeve 10. Then, the cylinder 12 is activated, causing the movable end of the cylinder 12 to retract. This will cause the first drive shaft 9 to insert into the end of the first drive sleeve 10, thus starting the machine tool 1. The machine tool 1 will drive the cutting tool to rotate, and the surface of the bolt ball to be processed will be continuously brought closer to the cutting tool via the worktable for processing. In this way, when it is necessary to switch cutting tools, the tool changer 2 can be rotated and slid to switch directly, eliminating the need to repeatedly clamp different cutting tools, greatly simplifying the processing process and improving processing efficiency.

[0034] In summary, during the entire process of use, different machining tools can be seamlessly switched by changing the tool wheel 2, drive components, and fixing components. The entire process no longer requires the user to repeatedly clamp different machining tools, which greatly simplifies the operation and effectively improves efficiency.

[0035] Meanwhile, since the processing tools are switched by the tool changer 2 throughout the entire processing process, programmed automated operation can be achieved, thereby reducing labor intensity and avoiding dangers caused by improper manual operation, making it safer to use.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
