Description

Technical Field

[0001] The invention relates to the technical field of machining machine tools, and in particular to an axle box swing head device and a blade five-axis machining system. Background Art

[0002] The five-axis machining center with spindle swing is generally used for the processing of large workpieces. The existing axle box swing head device is installed on the guide rail to realize its sliding, and is locked by the guide rail clamp. The guide rail clamp is a braking device installed on the slider of the linear guide, or a mobile clamping device designed as an integral part of the slider. The existing guide rail clamp needs to be manually locked. When the moving part stops at a certain position, the operator can manually lock the guide rail clamp. At the same time, before the moving part moves next time, the guide rail clamp must be manually opened, otherwise it will damage the guide rail or cause the motor to overload; however, manual locking cannot meet the requirements of rapid locking and positioning of the rotary axis of the five-axis machine tool.

[0003] However, manually locking the slider on the linear guide to prevent displacement of the moving parts and the guide is not a good choice. Especially in some heavy-loaded working environments, it is easy to cause significant irreversible damage to the linear guide, causing the linear guide to lose its original movement accuracy.

[0057] Combine the following Figure 1-Figure 9 The present invention describes an axle box swing head device. The axle box swing head device includes: a spindle swing head clamping mechanism 1, a spindle swing head guide mechanism 2, a spindle swing head power mechanism 3, a spindle swing head detection mechanism 4 and an arc brake pad 111. The axle box swing head device mainly has two major bearing components, namely the spindle box body 5 and the B-axis box body 6. The spindle swing head clamping mechanism 1 is arranged on the upper part of the spindle box body 5, the spindle swing head guide mechanism 2 is arranged at the front center of the B-axis box body 6, the spindle swing head power mechanism 3 is installed in the central part of the B-axis box body 6, and the spindle swing head detection mechanism 4 is arranged at the front center of the B-axis box body 6. The arc brake pad 111 and the spindle swing head clamping mechanism 1 are both arranged on the spindle box body 5.

[0058] The spindle swing head clamping mechanism 1 comprises: an oil inlet block 108, a fixed end locking plate 102, a rotating end locking plate 101 and an elastic member.

[0059] The oil inlet block 108 has a hydraulic passage (not shown in the figure), a proximity switch 109 and a pneumatic muffler 110. The oil inlet block 108 has an oil inlet and an oil outlet to realize oil inlet and oil outlet, thereby providing active driving force for the main shaft swing head clamping mechanism 1. The oil inlet block 108 is connected to the oil supply equipment.

[0060] The fixed end locking plate 102 is arranged on the oil inlet block 108, and a first locking block 1141 is arranged at one end of the fixed end locking plate 102 close to the arc brake pad 111, and the first locking block 1141 is located at one side of the arc brake pad 111; the rotating end locking plate 101 is rotatably connected to the fixed end locking plate 102 through the locking rotating shaft 103, and a second locking block 1142 is arranged at one end of the rotating end locking plate 101 close to the arc brake pad 111, and the second locking block 1142 is located at the other side of the arc brake pad 111. Through the cooperation of the first locking block 1141 and the second locking block 1142, the action of clamping or loosening the arc brake pad 111 can be realized, so as to realize the locking or loosening action.

[0061] The elastic member is disposed between one end of the fixed end locking plate 102 away from the arc brake pad 111 and one end of the rotating end locking plate 101 away from the arc brake pad 111. The elastic member provides a rotational force for the rotating end locking plate 101, and the rotating end locking plate 101 is driven to rotate by the elastic member, so that the second locking block 1142 is close to the first locking block 1141 to clamp the arc brake pad 111.

[0062] When the spindle swing head clamping mechanism 1 is in a locked state, the elastic member abuts against the rotating end locking plate 101, and drives the rotating end locking plate 101 to rotate in the first direction (in the figure) around the locking rotation axis 103, so that the second locking block 1142 clamps the arc brake pad 111; when the spindle swing head clamping mechanism 1 is in a loose state, the oil inlet block 108 drives the elastic member to move, and the elastic member drives the rotating end locking plate 101 to rotate in the second direction around the locking rotation axis 103, so that the second locking block 1142 releases the arc brake pad 111. It can be understood that the first direction and the second direction are opposite directions to each other, so as to respectively realize the two actions of clamping or loosening the brake pad.

[0063] Specifically, the elastic member is composed of a disc spring group 104 and a core shaft 105. The disc spring group 104 is installed on the rotating end locking plate 101 through the core shaft 105. One end of the core shaft 105 is inserted into the oil chamber of the oil inlet block 108, and the oil chamber is divided into an upper sealing chamber and a lower sealing chamber. When the hydraulic oil begins to enter the oil inlet of the oil inlet block 108, the volume of the upper sealing chamber increases and the volume of the lower sealing chamber decreases, thereby driving the core shaft 105 to move downward, and driving the rotating end locking plate 101 to rotate in the second direction through the elastic member, and the second locking block 1142 releases the arc brake pad 111. In addition, since there is a proximity switch 109 inside the oil inlet block 108, when the core shaft 105 touches the proximity switch 109, the oil supply will stop. At this time, the spindle swing head clamping mechanism 1 is in a completely relaxed state. Limit blocks 115 are provided on both sides of the rotating end locking plate 101 to limit the core shaft 105 from escaping.

[0064] The present invention provides an axle box swing head device, which includes: a spindle swing head clamping mechanism 1 and an arc brake pad 111; the arc brake pad 111 and the spindle swing head clamping mechanism 1 are both arranged on the spindle box body 5, and the spindle swing head clamping mechanism 1 includes: an oil inlet block 108, a fixed end locking plate 102, a rotating end locking plate 101 and an elastic member; the fixed end locking plate 102 is arranged on the oil inlet block 108, and a first locking block 1141 is provided at one end of the fixed end locking plate 102 close to the arc brake pad 111, and the first locking block 1141 is located on one side of the arc brake pad 111; the rotating end locking plate 101 is rotatably connected to the fixed end locking plate 102 through a locking rotating shaft 103, and a second locking block is provided at one end of the rotating end locking plate 101 close to the arc brake pad 111 1142, the second locking block 1142 is located on the other side of the arc brake pad 111; the elastic member is arranged between one end of the fixed end locking plate 102 away from the arc brake pad 111 and one end of the rotating end locking plate 101 away from the arc brake pad 111; when the spindle swing head clamping mechanism 1 is in a locked state, the elastic member abuts against the rotating end locking plate 101, and drives the rotating end locking plate 101 to rotate in the first direction around the locking rotation axis 103, so that the second locking block 1142 clamps the arc brake pad 111; when the spindle swing head clamping mechanism 1 is in a relaxed state, the oil inlet block 108 drives the elastic member to move, and the elastic member drives the rotating end locking plate 101 to rotate in the second direction around the locking rotation axis 103, so that the second locking block 1142 releases the arc brake pad 111. The present invention provides an axle box swing head device, which provides a clamping mechanism for an arc brake pad 111 to replace the direct locking of the guide rail in the prior art.
