Description

Technical Field

[0001] This utility model relates to the technical field of milling and turning composite equipment, specifically a quick-release fixture structure for a multi-axis, multi-channel milling and turning composite equipment. Background Technology

[0002] Milling and turning composite equipment, as an important piece of equipment in the field of modern precision machining, has significantly improved the processing efficiency of complex parts with its multi-axis linkage and multi-channel machining capabilities, and is becoming a key piece of equipment in high-end manufacturing fields such as aerospace, automobile manufacturing (especially new energy components) and medical devices.

[0003] One problem with existing milling and turning machines is that when machining parts of different shapes, it is necessary to change the clamping radii or shapes of the clamps. Changing the clamps requires manually unscrewing the screws with a hex wrench, which is not only time-consuming but also physically demanding for the operator. Therefore, we propose a quick-release clamping structure for multi-axis, multi-channel milling and turning machines. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenient assembly and disassembly, thereby providing a quick-release fixture structure for a multi-axis, multi-channel milling and turning composite equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-release fixture structure for a multi-axis, multi-channel milling and turning composite equipment includes a machine tool base. A base is fixedly installed on the inner wall of the machine tool base. A hydraulic drive seat is provided on the outer wall of the base. A sliding groove is formed on the surface of the hydraulic drive seat. A quick-replacement disassembly device is provided on the outer wall of the hydraulic drive seat. The disassembly device includes a T-shaped locating pin. The T-shaped locating pin is slidably installed on the inner wall of the sliding groove of the hydraulic drive seat. A slot and a sliding groove are respectively formed on the outer wall and top of the T-shaped locating pin. A fixture seat is provided on the outer wall of the T-shaped locating pin. An elastic plate is fixedly installed on the side of the fixture seat near the T-shaped locating pin. A triangular block is fixedly installed on the end of the elastic plate away from the fixture seat. An abutment rod is slidably installed on the inner wall of the sliding groove of the T-shaped locating pin. A semi-circular block is fixedly installed on the outer wall opposite to the abutment rod.

[0007] Preferably, the elastic plate is slidably installed on the inner wall of the slot, and the elastic plate is elastically configured. The bottom surface of the triangular block is inclined. The clamp seat is fixedly installed on the end of the elastic plate away from the triangular block. The abutment rod is A-shaped. The semi-arc block is located on the movement trajectory of the inclined surface of the triangular block. The ends of the right abutment rod and the left abutment rod away from the rotating shaft respectively contact the outer wall of the elastic plate, and the contact ends of the right abutment rod and the left abutment rod are arc-shaped. The curved spring is fan-shaped.

[0008] Preferably, a milling and turning cover is fixedly installed on the top of the machine tool base, a control panel is fixedly installed on the outer wall of the front of the milling and turning cover, and an observation door is slidably installed on the front of the milling and turning cover.

[0009] By employing the above technical solution, this utility model provides a quick-release clamping structure for a multi-axis, multi-channel milling and turning composite equipment. The beneficial effects are as follows: Through the design of the triangular locking block, combined with the semi-circular block, the triangular locking block can be triggered to disengage from its locking position by simply pulling the contact rod with one hand, achieving rapid separation of the clamping seat from the T-shaped positioning pin. This significantly improves the time required for quick disassembly and saves the physical effort required during installation. Furthermore, the curved spring, combined with the right and left abutments, maintains the elasticity of the elastic plate, preventing elasticity attenuation due to metal fatigue.

[0017] Example 1

[0018] A quick-release fixture structure for a multi-axis, multi-channel milling and turning composite equipment, such asFigures 1-4 As shown, the machine tool includes a machine tool base 1, a base 14 fixedly installed on the inner wall of the machine tool base 1, a hydraulic drive seat 15 provided on the outer wall of the base 14, a sliding groove opened on the surface of the hydraulic drive seat 15, and a quick-replacement disassembly device 2 provided on the outer wall of the hydraulic drive seat 15. The disassembly device 2 includes a T-shaped positioning pin 21, which is slidably installed on the inner wall of the sliding groove of the hydraulic drive seat 15. The outer wall and top of the T-shaped positioning pin 21 are respectively provided with a slot and a sliding groove. A clamp seat 24 is provided on the outer wall of the T-shaped positioning pin 21. An elastic plate 22 is fixedly installed on the side of the clamp seat 24 near the T-shaped positioning pin 21. A triangular block 23 is fixedly installed on the end of the elastic plate 22 away from the clamp seat 24. An abutment rod 25 is slidably installed on the inner wall of the sliding groove of the T-shaped positioning pin 21. A semi-circular block 26 is fixedly installed on the outer wall opposite to the abutment rod 25.

[0019] The disassembly and assembly device 2 also includes a connecting rod 27, a rotating shaft 28, a right abutment rod 29, a left abutment rod 210, and a curved spring 211. The connecting rod 27 is fixedly installed on the outer wall opposite to the elastic plate 22. The rotating shaft 28 is fixedly installed on the inner wall of the connecting rod 27 away from the clamp seat 24. The right abutment rod 29 is rotatably installed on the outer wall of the rotating shaft 28. The left abutment rod 210 is rotatably installed on the outer wall at the middle end of the rotating shaft 28. The two ends of the curved spring 211 are respectively fixedly installed on the outer walls opposite to the right abutment rod 29 and the left abutment rod 210.

[0020] The outer wall and top of the T-shaped positioning pin 21 are respectively provided with a slot and a sliding groove. The elastic plate 22 is slidably installed on the inner wall of the slot and is elastically set. The bottom surface of the triangular block 23 is set as an inclined surface. The clamp seat 24 is fixedly installed on the end of the elastic plate 22 away from the triangular block 23. The abutment rod 25 is set as an A-shape. The semi-arc block 26 is located on the movement trajectory of the inclined surface of the triangular block 23. The ends of the right abutment rod 29 and the left abutment rod 210 away from the rotating shaft 28 respectively contact the outer wall of the elastic plate 22 and the contact ends of the right abutment rod 29 and the left abutment rod 210 are set as an arc. The curved spring 211 is set as a fan shape.

[0021] A milling and turning cover 11 is fixedly installed on the top of the machine tool base 1. A control panel 12 is fixedly installed on the outer wall of the front of the milling and turning cover 11. An observation door 13 is slidably installed on the front of the milling and turning cover 11.

[0022] In use, the quick-release structure of the clamping fixture in this multi-axis, multi-channel milling and turning composite equipment allows the operator to slide the observation door 13 to the left, place the aluminum rod or other workable metal on the inner wall of the clamping seat 24, and activate the hydraulic system outside the machine tool base 1. The hydraulic system controls the hydraulic drive seat 15 to clamp the clamping seat 24 inward. After closing the observation door 13, the operator can operate the control panel 12 to process the workpiece. When it is necessary to change to a different type of clamping seat 24, the operator pulls the contact rod 25 upward. The contact rod 25 moves the semi-circular block 26 upward. After the semi-circular block 26 contacts the inclined surface of the bottom of the triangular locking block 23, the triangular locking block 23 causes the elastic plate 22 to bend and deform outward. After the outer wall of the triangular locking block 23 touches the apex of the semi-circular block 26, the triangular locking block 23 also deforms to its peak value. At this time, pulling out the clamping seat 24 achieves the effect of quick disassembly. When the clamp seat 24 needs to be replaced, the elastic plate 22 is aligned with the slot on the T-shaped positioning pin 21 and pushed inward into the clamp seat 24. After moving to the end, the triangular locking block 23 will engage with the end of the slot on the T-shaped positioning pin 21. The right abutment rod 29 and the left abutment rod 210, together with the curved spring 211, abut against the elastic plate 22, thereby maintaining the elasticity of the elastic plate 22. Through the setting of the triangular locking block 23, in conjunction with the semi-circular block 26, the triangular locking block 23 can be triggered to disengage from the locking position by simply pulling the abutment rod 25 with one hand, realizing the quick separation of the clamp seat 24 from the T-shaped positioning pin 21, which significantly improves the quick disassembly time and saves the physical strength required for installation. The curved spring 211, together with the right abutment rod 29 and the left abutment rod 210, maintains the elasticity of the elastic plate 22 and avoids elasticity decay caused by metal fatigue.
