Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to a spindle rotary head for a five-axis gantry milling machine. Background Technology

[0002] The spindle rotary head of a five-axis gantry milling machine is a key component of a machine tool used for high-precision and high-efficiency machining. It is widely used in high-end manufacturing industries such as aerospace, automobile manufacturing, and mold processing. It is installed on the spindle of a five-axis gantry milling machine and is used to fix and drive the cutting tool or workpiece to perform rotary machining, enabling high-precision machining of complex-shaped parts.

[0003] In the field of machine tool processing, the traditional method of installing spindle rotary heads mainly relies on bolt fixing. This installation method requires tightening each bolt individually, which is cumbersome and time-consuming. Especially in scenarios with high machining accuracy requirements, the tightening torque of the bolts must be precisely controlled, which undoubtedly further increases the difficulty and complexity of installation. In addition, bolts are prone to loosening or corrosion during long-term use. This not only makes disassembly difficult but may also damage the threads, thereby affecting the normal maintenance and service life of the equipment. At the same time, due to the single fixing method of bolts, under high-speed and high-load machining conditions, bolts are prone to loosening due to vibration. This not only reduces machining accuracy but may also affect the overall stability of the equipment, causing many inconveniences to production. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a five-axis gantry milling machine spindle rotary head.

[0005] This utility model is achieved using the following technical solution: a five-axis gantry milling machine spindle rotary head, including a mounting sleeve, a connecting block is snapped into the inside of the mounting sleeve, a rotary head is fixedly connected to the bottom of the connecting block, protrusions are fixedly connected to both sides of the outer surface of the connecting block, and circular grooves are formed on the inner walls of the connecting block and the protrusions. A spring is fixedly connected to the inner wall of the circular groove, and a locking pin is fixedly connected to the surface of the spring. A groove is formed on the inner wall of the mounting sleeve, and a second groove is formed on the inner wall of the mounting sleeve. A positioning seat is fixedly connected to the outer surface of the mounting sleeve, and a pop-out groove is formed on the inner wall of the second groove.

[0007] The above technical solution enables rapid assembly of the rotating head and the mounting sleeve through the cooperation of the locking pin and the pop-out slot, greatly reducing the complexity and time consumption of traditional installation methods. The reinforcement mechanism further fixes the position of the locking pin through the cooperation of the locking rod and the positioning hole, ensuring that the rotating head remains stable during subsequent use and is not easy to loosen or fall off, thus improving the reliability and safety of the equipment.

[0008] As a further improvement to the above solution, the second spring is fixedly connected to the inner bottom wall of the positioning seat.

[0009] As a further improvement to the above solution, the protrusion is adapted to both the first and second grooves.

[0010] As a further improvement to the above solution, the locking pin is adapted to the pop-out slot.

[0011] The above technical solutions improve the reliability and stability of the locking mechanism, ensuring that the rotating head will not easily loosen or fall off after installation.

[0012] As a further improvement to the above solution, a spring three is fixedly connected to the inner wall of the mounting sleeve, and the spring three is in contact with the connecting block.

[0013] Through the above technical solution, the rotating head can be easily disassembled by the reset action of spring three, which reduces the complexity and time consumption in the disassembly process, improves the maintenance efficiency of the equipment, facilitates the quick replacement or repair of the rotating head, and reduces equipment downtime.

[0014] As a further improvement to the above solution, the positioning hole is adapted to the locking rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] During installation, this invention utilizes the elastic restoring action of springs one and two, along with the cooperation between the locking pin and the pop-out groove, to quickly position the rotating head. The reinforcement mechanism, through the cooperation of the locking rod and the positioning hole, further secures the position of the locking pin, ensuring the rotating head remains stable during subsequent use and is not prone to loosening or falling off, thus improving the reliability and safety of the equipment. During disassembly, the locking is released by pulling down the operating block, and the restoring force of spring three allows for easy separation of the rotating head from the mounting sleeve. This not only improves disassembly and assembly efficiency and reduces operation time but also avoids the problems of insecure installation or difficult disassembly caused by improper tightening or loosening of bolts in traditional installation methods.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Example:

[0026] Please combine Figure 1-5 This embodiment of a five-axis gantry milling machine spindle rotary head includes a mounting sleeve 1, a connecting block 2 is snapped into the inside of the mounting sleeve 1, a rotary head 3 is fixedly connected to the bottom of the connecting block 2, protrusions 4 are fixedly connected to both sides of the outer surface of the connecting block 2, circular grooves are opened on the inner walls of the connecting block 2 and the protrusions 4, a spring 5 is fixedly connected to the inner wall of the circular groove, a locking pin 6 is fixedly connected to the surface of the spring 5, a groove 7 is opened on the inner wall of the mounting sleeve 1, a groove 8 is opened on the inner wall of the mounting sleeve 1, a positioning seat 9 is fixedly connected to the outer surface of the mounting sleeve 1, a pop-out groove 10 is opened on the inner wall of the groove 8, a positioning hole 11 is opened on the surface of the locking pin 6, and a reinforcing mechanism 12 is provided inside the positioning seat 9.

[0027] The reinforcing mechanism 12 includes a second spring 121. A contact ring 122 is fixedly connected to the top of the second spring 121. A locking rod 123 is fixedly connected to the upper surface of the contact ring 122. A pull rod 124 is fixedly connected to the lower surface of the contact ring 122. An operating block 125 is fixedly connected to the bottom end of the pull rod 124. When installing the rotating head, first align the protrusion 4 on the surface of the connecting block 2 with the groove 7 of the mounting sleeve 1. Press the locking pins 6 on both sides to compress the spring 5 and retract it into the circular groove. Insert the protrusion 4 into the groove 7. When the protrusion 4 moves to the top of the groove 7, it enters the groove 8. Rotate the connecting block 2 to make the protrusion 4 slide in the groove 8. Pull down the operating block 125, which drives the contact ring 122 to descend via the pull rod 124 and compresses the second spring 121, causing the locking rod 123 to move to the bottom of the positioning seat 9. When the protrusion 4 slides to the position of the pop-out groove 10, the first spring 5 resets and drives the locking pin 6 to engage inside the pop-out groove 10. The locking pin 6 passes through the pop-out groove 10 on the surface of the second groove 8 and the positioning seat 9. The positioning hole 11 is aligned with the locking rod 123. Release the operating block 125, the second spring 121 resets, the locking rod 123 rises and passes through the positioning hole 11 of the locking pin 6, fixing the position of the locking pin 6 and completing the assembly. The operator connects the mounting sleeve 1 to the spindle. Through quick installation, the rotating head 3 can be quickly assembled onto the surface of the spindle.

[0028] Spring 2 121 is fixedly connected to the inner bottom wall of the positioning seat 9.

[0029] The protrusion 4 is adapted to the first groove 7 and the second groove 8, ensuring that the protrusion 4 can be smoothly inserted into the first groove 7 and slide in the second groove 8.

[0030] The locking pin 6 is adapted to the pop-out groove 10, ensuring that the locking pin 6 can be accurately engaged in the pop-out groove 10 under the reset action of the spring 5, thereby locking the connecting block 2.

[0031] Spring 3 13 is fixedly connected to the inner wall of mounting sleeve 1. Spring 3 13 is in contact with connecting block 2. During installation, when protruding block 4 is inserted into groove 7, connecting block 2 is inserted into mounting sleeve 1 and compresses spring 3 13. During disassembly, first pull down operating block 125 to release locking rod 123 from locking pin 6, press locking pin 6 to retract it, rotate connecting block 2 to make protruding block 4 slide through groove 2 8. When protruding block 4 moves to the position of groove 7, spring 3 13 automatically resets, pushing protruding block 4 out of groove 7, thus achieving disassembly.

[0032] The positioning hole 11 is adapted to the locking rod 123.

[0033] The implementation principle of a five-axis gantry milling machine spindle rotary head in this application embodiment is as follows: During installation, firstly, align the protrusion 4 on the surface of the connecting block 2 with the groove 7 of the mounting sleeve 1, ensuring accurate alignment. At this time, the protrusion 4 is compatible with the groove 7 and the groove 8, allowing for smooth insertion and sliding. Press the locking pins 6 on both sides to compress the spring 5 and retract it into the circular groove. Under the compression of the spring 5, the locking pin 6 will not obstruct the insertion of the protrusion 4. Subsequently, insert the protrusion 4 into the groove 7. When the protrusion 4 moves... Upon reaching the top of the first groove 7, the device enters the interior of the second groove 8. Rotating the connecting block 2 allows the protrusion 4 to slide within the second groove 8. At this point, the inner wall of the second groove 8 blocks the locking pin 6, preventing it from popping out and ensuring the protrusion 4 can slide smoothly to the predetermined position. Pulling down the operating block 125 causes the pull rod 124 to lower the contact ring 122 and compress the second spring 121, moving the locking rod 123 to the bottom of the positioning seat 9. At this point, the second spring 121 is fixedly connected to the inner bottom wall of the positioning seat 9, providing stability for the reinforcing mechanism 12. Support and reset power: When the protrusion 4 slides to the position of the pop-out groove 10, the spring 5 resets and drives the locking pin 6 to engage inside the pop-out groove 10. Since the locking pin 6 is compatible with the pop-out groove 10, it can be accurately engaged, thus locking the connecting block 2. At this time, the locking pin 6 penetrates the pop-out groove 10 on the surface of the groove 8 and the positioning seat 9. The positioning hole 11 on the surface of the locking pin 6 is aligned with the locking rod 123. When the operating block 125 is released, under the reset action of the spring 121, the locking rod 123 rises and penetrates the positioning hole 11 on the surface of the locking pin 6. The top of 123 contacts the inner bottom wall of the positioning seat 9, thereby further fixing the position of the locking pin 6 and completing the assembly. When disassembly is required, first pull down the operating block 125 to release the locking rod 123 from locking the locking pin 6, then press the locking pin 6 to retract it, rotate the connecting block 2 to make the protrusion 4 slide through the groove 8. When the protrusion 4 moves to the position of the groove 7, the spring 13 on the inner wall of the mounting sleeve 1 automatically resets, pushing the protrusion 4 out of the groove 7, and then separating and disassembling the connecting block 2 and the rotating head 3 from the mounting sleeve 1.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
