DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-9 , and further illustrate the technical solution of the present invention through specific implementation methods.

[0025] The present invention provides a nonferrous metal high-speed processing machine tool. Three groups of feed assemblies arranged perpendicular to each other are arranged in a shell 4, which are used to drive the movement of a main tool head 5 and a chuck fixture 6. The feed assembly includes a supporting part, on which a moving part is slidably installed. The moving part includes a feed sliding seat 101.

An extrusion rod 106 is fixedly installed on each extrusion head 107. An adjustment chamber 102 is also fixedly installed on the feed sliding seat 101. The adjustment chamber 102 is provided with through holes with the same number and coaxial arrangement as the extrusion head 107. A sliding adjustment frame 103 is also slidably installed in the adjustment chamber 102. The sliding adjustment frame 103 is provided with slide rail grooves 104 with the same number as the extrusion rod 106. Each slide rail groove 104 is slidably matched with the corresponding extrusion rod 106 through a sliding pin 105. A rack 109 is fixedly installed on the sliding adjustment frame 103. The feed slide seat 101 is slidably arranged on the outer surface of the screw rod 301, and the feed slide seat 101 and the slide rod 302 are slidably matched through the sliding sleeve 110, and the feed slide seat 101 and the screw rod 301 are threadedly matched through at least three extrusion heads 107. An upper cover plate 108 is fixedly mounted on the adjustment chamber 102, and a slide groove is opened in the middle of the upper cover plate 108, and a rack 109 is slidably arranged in the slide groove.

[0026] A switching part is fixedly mounted on the feed slide 101, and the switching part includes a limiting block bracket 210, on which an arc limiting frame 207 is fixedly mounted, and a brake block 205 and a swing arm 209 are also rotatably mounted on the limiting block bracket 210, and the brake block 205 and the swing arm 209 are rotatably matched, and two symmetrically arranged inclined grooves 2051 are provided on the brake block 205, and active columns 206 are overlapped in the two inclined grooves 2051, and a magnetic swing rod 208 is overlapped between the two active columns 206, and the magnetic swing rod 208 is fixedly mounted on the swing arm 209, and a toothed disc 204 is fixedly mounted on the brake block 205. The limiting block bracket 210 is fixedly connected to the feed slide 101, and the two active columns 206 and the magnetic swing rod 208 are magnetically matched, and the two active columns 206 are frictionally matched with the inclined grooves 2051 and the arc limiting frame 207. A gear bracket 201 is fixedly mounted on the upper cover plate 108, and a second gear 203 and a first gear 202 are rotatably mounted on the gear bracket 201. The first gear 202 and the second gear 203 are fixedly matched, wherein the second gear 203 is meshed with the toothed disc 204 for transmission, and the first gear 202 is meshed with the rack 109 for transmission. An electric cylinder bracket 211 is also fixedly mounted on the limit block bracket 210, and an electric cylinder 212 is movably mounted on the electric cylinder bracket 211. A linkage rod 213 is also rotatably mounted on the limit block bracket 210, and the linkage rod 213 is fixed to the swing arm 209 through a rotating shaft, and the telescopic rod end of the electric cylinder 212 is movably connected to one end of the linkage rod 213. A dust cover 214 is arranged on the outside of the regulating chamber 102, and the dust cover 214 is fixedly mounted on the feed slide seat 101.

[0027] The support part includes two support side plates 303, between which a slide bar 302 is fixedly installed, and a screw rod 301 rotatably installed between the two support side plates 303 is arranged on the side of the slide bar 302, and a feed motor 306 for driving the screw rod 301 to rotate is fixedly installed on one of the support side plates 303. A transmission belt 304 is also rotatably arranged between the two support side plates 303, and a transmission motor 305 for driving the transmission belt 304 to rotate is fixedly installed on one of the support side plates 303, which is used to drive the moving part to move quickly on the screw rod 301.

[0028] The working principle of a non-ferrous metal high-speed processing machine tool disclosed in the present invention is as follows: first, the non-ferrous metal to be processed is fixed on the chuck fixture 6, and the horizontal movement of the chuck fixture 6 is controlled by two vertically arranged feed components, and the vertical movement of the main tool head 5 is controlled by another feed component. Since the tool needs to be aligned before processing, the transmission machine tool feed device can only move at a low speed, which consumes a lot of time. The present invention controls the movement of the telescopic rod of the electric cylinder 212, and the telescopic rod of the electric cylinder 212 will drive the connecting rod 213 to swing, and the swing of the connecting rod 213 will drive the swing arm 209 to swing synchronously, and the swing of the swing arm 209 will drive the magnetic swing rod 208 to follow the movement, and the movement of the magnetic swing rod 208 will squeeze one of the active columns 206 (depending on the swing direction of the magnetic swing rod 208), so that the active column 206 moves along the side with a larger space of the inclined groove 2051, and at this time, the other active column 206 will be affected by the friction of the arc-shaped limiting frame 207 and also move toward the side with a larger space of the inclined groove 2051. At this time, the magnetic swing rod 208 contacts the active column 206 to drive the brake block 205 to swing, the swing of the brake block 205 will drive the toothed disc 204 to swing, the swing of the toothed disc 204 will drive the second gear 203 to swing, the swing of the second gear 203 will drive the first gear 202 to swing, the swing of the first gear 202 will drive the rack 109 to move in a straight line, the movement of the rack 109 will drive the sliding adjustment frame 103 to move, the sliding adjustment frame 103 drives the sliding pin 105 and the extrusion rod 106 to move along the radial direction of the screw rod 301 through the slide rail groove 104, so that the extrusion head 107 engages with the thread groove of the screw rod 301, and at this time, the rotation of the screw rod 301 will drive the feed sliding seat 101 to move slowly, which can improve the processing accuracy during the processing. On the contrary, when the extrusion head 107 is not engaged with the threaded groove of the screw rod 301, the feed slide seat 101 and the screw rod 301 are in a sliding state. At this time, by controlling the transmission motor 305, the transmission motor 305 drives the feed slide seat 101 to slide quickly on the slide rod 302 and the screw rod 301 through the transmission belt 304, thereby quickly moving the feed slide seat 101 to a specified position (the feed slide seat 101 is used to install the moved parts, such as the chuck fixture 6). For this purpose, a grating ruler needs to be set in the moving direction of the feed slide seat 101 to detect the moving position of the feed slide seat 101, and the position data is fed back to the control system, and then the feed slide seat 101 is accurately adjusted through the feed motor 306.When the extrusion head 107 engages into the threaded groove of the screw rod 301, a radial force will be applied to the extrusion head 107 when the screw rod 301 rotates, which will cause the extrusion head 107 to have a tendency of radial displacement. The force will be transmitted to the sliding pin 105 through the extrusion rod 106, and then to the sliding adjustment frame 103 through the sliding pin 105, and the sliding adjustment frame 103 will transmit it to the rack 109, and the rack 109 will transmit it to the first gear 202, the first gear 202 will transmit it to the second gear 203, the second gear 203 will transmit it to the toothed disc 204, and the toothed disc 204 will transmit it to the brake block 205. At this time, the brake block 205 acts as an active component. However, when the brake block 205 acts as an active moving component, the swing direction of the brake block 205 will be the same as the direction of the friction force applied to one of the active columns 206 by the arc limiting frame 207. At this time, the active column 206 will move toward the direction with smaller space in the inclined groove 2051, thereby causing it to get stuck. Therefore, the above operation can be completed by setting a relatively low-power electric cylinder 212, while also reducing the overall volume.
