Description

TECHNICAL FIELD

[0001] The present application relates to the field of numerical control machine tools, and in particular to an automatic feeding and discharging numerical control machine tool. BACKGROUND

[0002] A numerical control machine tool is a kind of automatic machine tool equipped with a program control system. The control system can logically process programs with control programming or other instructions, and translate them into code numbers, and input them into the numerical control device through a signal carrier. After operation and processing, the numerical control device sends various control signals to control the machine tool, and automatically processes parts according to the shape and size required by the drawing.

[0003] The existing numerical control machine tool is generally also provided with an automatic feeding and discharging device to replace the operator to feed and discharge, so as to avoid the operator from entering the numerical control machine tool to feed and discharge, thereby improving the operation safety; the automatic feeding and discharging device is generally arranged at the operating position of the operator, that is, at the inlet and outlet position of the numerical control machine tool, so that when a fault needs to be checked, the automatic feeding and discharging device needs to be removed, which is very troublesome. SUMMARY

[0004] In order to solve the technical problem that the automatic feeding and discharging device affects the use of the inlet and outlet by the operator, the present application provides an automatic feeding and discharging numerical control machine tool.

[0005] The automatic feeding and discharging numerical control machine tool provided by the present application adopts the following technical scheme:

[0006] An automatic feeding and discharging numerical control machine tool, comprising a machine tool body, a vertical feeding device, an inlet and outlet device, and a vertical discharging device; the machine tool body is provided with an inlet and outlet; the inlet and outlet is open to the operating side and the upper side; the machine tool body is located between the vertical feeding device and the vertical discharging device, and the vertical feeding device and the vertical discharging device are located on both sides of the inlet and outlet; the inlet and outlet device is arranged on the upper end surface of the machine tool body and located directly above the inlet and outlet; the vertical feeding device is used to lift shaft raw materials and convey them to the inlet and outlet device; the inlet and outlet device transfers the shaft raw materials to a three-jaw chuck and takes off the processed shaft workpieces from the three-jaw chuck; the vertical discharging device is used to receive the shaft workpieces and convey them from top to bottom.

[0007] By adopting the above technical scheme, the vertical feeding device, the feeding and discharging device and the vertical discharging device are used for feeding and discharging, meanwhile, the vertical feeding device and the vertical discharging device are located on both sides of the machine tool body, and the feeding and discharging device is located directly above the feeding and discharging opening, so that the feeding and discharging can be completed without affecting the blocking of the feeding and discharging opening, thereby the operator can conveniently use the feeding and discharging opening for maintenance, manual feeding and discharging and other operations.

[0008] Optionally, the vertical feeding device comprises a vertical feeding frame, a vertical lifting mechanism arranged on the vertical feeding frame, a horizontally arranged feeding sliding frame arranged on the vertical feeding frame and a horizontal pushing mechanism arranged on the vertical feeding frame; the horizontal pushing mechanism is used for horizontally pushing the shaft raw material lifted by the vertical lifting mechanism to the feeding sliding frame; the vertical discharging device comprises a vertical discharging frame, a vertical conveying mechanism arranged on the vertical discharging frame and a horizontally arranged discharging sliding frame arranged on the vertical discharging frame; the feeding and discharging device comprises an intermediate support frame, an intermediate lifting seat vertically arranged on the intermediate support frame, an intermediate lifting mechanism used for driving the intermediate lifting seat to vertically move, a vertical extension frame horizontally arranged on the intermediate lifting seat, an intermediate translation mechanism used for driving the vertical extension frame to horizontally move, a horizontal switching mechanism arranged on the vertical extension frame and a pair of horizontal driving mechanisms; the horizontal switching mechanism comprises a horizontally arranged horizontal switching seat, a switching driving assembly used for driving the horizontal switching seat to horizontally rotate and a pair of receiving seats arranged at both ends of the horizontal switching seat; the horizontal driving mechanisms correspond to the receiving seats one by one, and the horizontal driving mechanisms are located directly above the corresponding receiving seats; the horizontal driving mechanisms are used for driving the shaft raw material on the receiving seats to horizontally enter into the three-jaw chuck or driving the shaft workpiece on the three-jaw chuck to horizontally enter into the receiving seat; in the initial state, the receiving seat away from the operation side is located between the feeding sliding frame and the discharging sliding frame and the three are on the same horizontal line.

[0009] By adopting the technical scheme, the shaft raw material is lifted by the vertical lifting mechanism, and then the horizontal pushing mechanism pushes the shaft raw material horizontally to the feeding sliding frame. With the mutual pushing of the shaft raw materials, the shaft raw materials enter the receiving seats. Then, the middle lifting seat descends, and then the switching driving assembly drives the horizontal switching seat to rotate, so that the empty receiving seat faces inward. Then, the vertical extension frame moves horizontally inward, and then the middle lifting seat ascends, so that the processed shaft workpiece reaches the empty receiving seat. Then, the three-jaw chuck releases the shaft workpiece, and then the horizontal driving mechanism drives the shaft workpiece to completely enter the receiving seat. Then, the vertical extension frame moves horizontally outward, and then the switching driving assembly drives the horizontal switching seat to rotate, so that the receiving seat loaded with the shaft raw material is on the inner side. Then, the vertical extension frame moves horizontally inward, and then the horizontal driving mechanism drives the shaft raw material to enter the three-jaw chuck. The three-jaw chuck starts to clamp the shaft raw material. Then, the middle lifting seat descends, and then the vertical extension frame moves horizontally outward. Then, the switching driving assembly drives the horizontal switching seat to rotate, so that the receiving seat loaded with the shaft workpiece faces inward. Then, the middle lifting seat ascends to reset. Then, with the entering of the shaft raw material, the shaft workpiece enters the discharging sliding frame. With the mutual force between the shaft workpieces, the shaft workpieces finally enter the vertical conveying mechanism and descend vertically along with the vertical conveying mechanism. In this way, the feeding and discharging are convenient, and the feeding and discharging ports are not blocked.

[0010] Optionally, V-shaped sliding grooves are formed on the upper end surfaces of the feeding sliding frame, the discharging sliding frame and the receiving seats, and the sliding grooves are open at both ends along the length direction thereof; in the initial state, the sliding grooves of the receiving seats, the feeding sliding frame and the discharging sliding frame far from the operation side are horizontally opposite.

[0011] By adopting the technical scheme, the V-shaped sliding grooves make the axial horizontal movement of the shaft workpiece more stable, and adapt to shaft workpieces of different diameters.

[0012] Optionally, a pair of horizontal support plates are formed on the lower part of the vertical extension frame; the horizontal support plates correspond to the horizontal driving mechanisms one by one; the horizontal driving mechanism comprises a separate support plate vertically movably arranged on the lower end surface of the corresponding side horizontal support plate, a separate driving assembly for driving the separate support plate, a separate pressing frame vertically and elastically movably arranged on the lower end surface of the separate support plate, a horizontal driving wheel rotatably connected to the bottom of the separate pressing frame, and a horizontal driving assembly for driving the horizontal driving wheel to rotate; the horizontal driving wheel is located directly above the corresponding side sliding groove.

[0013] By adopting the technical scheme, when not working, the separation support plate is at the uppermost end, so that the shaft member is conveniently put in and collision with the shaft raw material during the lifting process of the vertically extending frame after the material is put in is avoided; when working, the separation driving assembly drives the separation support plate to descend, in this process, the horizontal driving wheel is in contact with the shaft member, and since the separation pressing frame is vertically and elastically arranged, the horizontal driving wheel and the shaft member are not damaged, and shaft members with different diameters can be used.

[0014] Optionally, the upper feeding sliding frame is detachably connected to the vertical upper feeding frame; the lower feeding sliding frame is detachably connected to the vertical lower feeding frame; the receiving seat is detachably connected to the horizontal switching seat; the length of the receiving seat is equal to the length of the shaft raw material; the length of the upper feeding sliding frame and the lower feeding sliding frame is equal to several times the length of the shaft raw material.

[0015] By adopting the technical scheme, only the shaft raw material or the shaft workpiece that needs to be processed is on the receiving seat during feeding and discharging, so that accidental collision between the shaft members on the upper feeding sliding frame and the lower feeding sliding frame and the shaft members on the receiving seat during feeding and discharging is avoided.

[0016] Optionally, the upper feeding sliding frame, the lower feeding sliding frame and the receiving seat have multiple size specifications, and the difference between different size specifications is that the lengths are different; the vertical upper feeding device further comprises a vertical upper feeding base and an upper feeding horizontal adjusting mechanism arranged on the vertical upper feeding base; the vertical upper feeding frame is translationally arranged on the vertical upper feeding base and moves in a direction parallel to the length direction of the upper feeding sliding frame; the upper feeding horizontal adjusting mechanism is used to drive the vertical upper feeding frame; the vertical lower feeding device further comprises a vertical lower feeding base and a lower feeding horizontal adjusting mechanism arranged on the vertical lower feeding base; the vertical lower feeding frame is translationally arranged on the vertical lower feeding base and moves in a direction parallel to the length direction of the lower feeding sliding frame; the lower feeding horizontal adjusting mechanism is used to drive the vertical lower feeding frame.

[0017] By adopting the technical scheme, by replacing the upper feeding sliding frame, the lower feeding sliding frame and the receiving seat with corresponding size specifications, and then since the vertical upper feeding frame and the vertical lower feeding frame can be horizontally adjusted along the horizontal conveying direction of the shaft member, the upper feeding sliding frame, the lower feeding sliding frame and the receiving seat with corresponding size specifications are in contact with each other, which is conducive to horizontal conveying of the shaft member.

[0018] Optionally, the feeding and discharging device further comprises a horizontal adjusting mechanism; the horizontal adjusting mechanism is used to adjust the position of the intermediate support frame parallel to the length direction of the receiving seat,

[0019] By adopting the above technical solution, the position of the intermediate support frame parallel to the length direction of the receiving seat can be adjusted by the horizontal adjustment mechanism, so that the position of the receiving seat relative to the three-jaw chuck is the same when loading and unloading shaft parts of different lengths, which is beneficial for loading and unloading.

[0020] Optionally, the vertical length of the vertical extension frame can be adjusted.

[0021] By adopting the above technical solution, the vertical length of the vertical extension frame can be adjusted to adjust the vertical position of the receiving seat. This, combined with its V-shaped sliding groove, allows for the loading and unloading of shaft parts of different diameters.

[0022] Optionally, the vertical feeding rack is shaped like the letter "U"; the vertical lifting mechanism includes a pair of vertically distributed vertical lifting center rods, a pair of lifting chains, a vertical lifting drive assembly, and several evenly distributed lifting seats; the pair of vertical lifting center rods are rotatably connected between a pair of vertical parts of the vertical feeding rack; a pair of coaxially arranged vertical lifting sprockets are fixed on the vertical lifting center rods; the lifting chains are drivenly connected to the pair of vertically opposite vertical lifting sprockets; the lifting seats are fixed on the pair of lifting chains; the lifting seats have a V-shaped lifting groove with a horizontal opening that cooperates with the sliding groove on the front end face of the lifting chain in the direction of movement.

[0023] By adopting the above technical solution, the operator places the shaft material in the V-shaped lifting groove on the upper surface of the bottom lifting seat. Then, the lifting seat rises with a pair of lifting chains until the lifting groove of the lifting seat is aligned with the sliding groove of the loading slide frame. Then, the shaft material in the lifting groove of the lifting seat is pushed into the sliding groove of the loading slide frame by the horizontal pushing mechanism. This makes it convenient to lift the shaft material.

[0024] Optionally, the vertical unloading rack is shaped like the letter "U"; the vertical conveying mechanism includes a pair of vertically distributed vertical conveying center rods, a pair of vertical conveying chains, a vertical conveying drive assembly, and several evenly distributed conveying seats; the pair of vertical conveying center rods are rotatably connected between a pair of vertical parts of the vertical unloading rack; a pair of coaxially arranged vertical conveying sprockets are fixed on the vertical conveying center rods; the vertical conveying chains are drivenly connected to the pair of vertically opposite vertical conveying sprockets; the conveying seats are fixed on the pair of vertical conveying chains; the conveying seats have a V-shaped conveying groove with a horizontal opening that cooperates with the sliding groove on the rear end face of the vertical conveying chain in the direction of movement.

[0025] By adopting the technical scheme, the shaft workpiece closest to the conveying seat in the sliding groove of the blanking sliding frame is horizontally slid into the conveying groove of the conveying seat under the pushing of the subsequent workpiece, and then the pair of vertical conveying chains drives the conveying seat to descend, so that the blanking of the shaft workpiece is facilitated.

[0026] To sum up, the beneficial effects of the present application are:

[0027] 1. The feeding and discharging are completed at the same time, and the feeding and discharging ports are not blocked, so that the operator can conveniently use the feeding and discharging ports for maintenance, manual feeding and discharging, and other operations.
