Description

TECHNICAL FIELD

[0002] During the production and processing of metal rotating shafts, they need to be processed according to actual conditions. Usually, metal rotating shafts are concentrated and stacked on a feeding vibrating tray before processing, and then conveyed to a rotating shaft processing device (such as a milling machine) through the feeding vibrating tray.

[0003] The feeding vibrating tray usually needs to be provided with a pushing assembly, and the discharge end of the pushing assembly needs to be provided with a feeding assembly. The pushing assembly is used to convey the metal rotating shaft from the discharge end of the feeding vibrating tray to the feeding assembly. The feeding assembly is used to convey the metal rotating shaft to the milling cutter assembly. After the metal rotating shaft enters the feeding assembly, it will be moved to the milling cutter assembly position for processing by the push rod. Since the stroke of the push rod needs to pass through the position below the discharge end of the feeding assembly, the overall stroke of the push rod is relatively long, that is, the push rod needs to be elongated to a relatively long length to push the metal rotating shaft to the position of the milling cutter assembly. The elongation of the push rod is too large, which can easily cause the push rod to deviate from the axial direction when it is elongated, and the precision of the metal rotating shaft entering the milling cutter assembly can also be easily deviated, affecting the processing precision of the metal rotating shaft.

[0004] Therefore, further improvement is needed. INVENTION CONTENTS

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] See also Figure 8 The loading mechanism of the milling machine used for processing the metal rotating shaft includes a milling cutter assembly 11 and a movable support plate 2. A feeding frame 3 is fixedly connected to the movable support plate 2. A pushing assembly is provided above the feeding frame 3 for transferring the metal rotating shaft 1 from the screening vibration plate 4 to the top of the feeding frame 3. The feeding frame 3 is provided with a limiting structure for limiting the metal rotating shaft 1, so that the position of the metal rotating shaft 1 after entering the feeding frame 3 can be relatively stable.

[0029] The feeding frame 3 is connected to the feeding rod 5, and the feeding rod 5 is connected to the feeding cylinder 51. The feeding cylinder 51 can make the feeding rod 5 pass through the inner side of the feeding frame 3 and extend toward the milling cutter assembly 11 or retract toward the back of the milling cutter assembly 11. The movable support plate 2 is fixedly connected to the feeding cylinder 51. The movable support plate 2 is provided with an inner transmission part 21. The outer side of the inner transmission part 21 is connected to the outer transmission part 61. The outer transmission part 61 is connected to the push rod 6. The push rod 6 is connected to the driving cylinder 62. The driving cylinder 62 can make the push rod 6 push the movable support plate 2 and the feeding frame 3 through the outer transmission part 61 and the inner transmission part 21 to extend toward the milling cutter assembly 11 or retract toward the back of the milling cutter assembly 11.

[0030] When the metal shaft 1 enters the feeding frame 3, the driving cylinder 62 line moves the movable support plate 2, the feeding frame 3 and the feeding cylinder 51 close to the milling cutter assembly 11 through the push rod 6 until they reach the preset position. Then the feeding cylinder 51 enables the feeding rod 5 to push the metal shaft 1 to the position of the milling cutter assembly 11 for processing, which relatively shortens the extension stroke of the feeding rod 5. By setting the push rod 6 and the driving cylinder 62, the extension length stroke of the feeding rod 5 can be relatively shortened, reducing the chance of the feeding rod 5 being offset due to excessive extension length, thereby improving the processing accuracy of the metal shaft 1.

[0031] Furthermore, the vertical projections of the outer transmission part 61 and the inner transmission part 21 are circular in shape, and the outer transmission part 61 and the inner transmission part 21 are movably connected. The outer transmission part 61 and the inner transmission part 21 can also have an adjustment effect. When there is an installation tolerance between the drive cylinder 62 and the feeding cylinder 51, the outer transmission part 61 and the inner transmission part 21 can swing relative to each other to a certain extent, thereby avoiding the phenomenon of jamming between the outer transmission part 61 and the inner transmission part 21 due to installation tolerance.

[0032] Furthermore, the cross-section of the feeding frame 3 is in a V-shape with the opening facing upward, so that a limiting structure is formed on the inner side of the feeding frame 3. After the metal shaft 1 enters the feeding frame 3, it can lie flat on the bottom of the inner side of the feeding frame 3. Moreover, since the shape of the metal shaft 1 is circular, the axial position of the metal shaft 1 after entering the feeding frame 3 can be kept consistent, which facilitates the feeding rod 5 to push the metal shaft 1 to move.

[0033] Furthermore, a positioning plate 31 is provided on the side of the feed frame 3 facing away from the milling cutter assembly 11, and a positioning hole 311 corresponding to the feed rod 5 is provided on the positioning plate 31. The feed rod 5 passes through the positioning hole 311 and extends into the inner side of the feed frame 3. The feed rod 5 is not easily offset under the action of the positioning hole 311, so that the feed rod 5 can more accurately push the metal shaft 1 to the position of the milling cutter assembly 11, thereby further improving the processing accuracy.

[0034] Furthermore, the pushing assembly includes a feed pipe 41 for connecting to the discharge end of the screening vibrating plate 4. The discharge end of the feed pipe 41 is connected to a material receiving portion 7. After the metal shaft 1 leaves the screening vibrating plate 4, it will enter the feed pipe 41. The rear metal shaft 1 will push the front metal shaft 1 forward until it enters the material receiving portion 7.

[0035] The discharge end of the receiving part 7 is provided with a receiving plate 8, and the discharge end of the receiving plate 8 is arranged above the feeding frame 3. The receiving plate 8 is provided with a pushing block 9 and a pushing cylinder 91. The transmission end of the pushing cylinder 91 is connected to the pushing block 9. The pushing cylinder 91 can make the pushing block 9 move back and forth along the direction from the receiving part 7 to the discharge end of the receiving plate 8. The metal rotating shaft 1 entering the receiving plate 8 can enter the feeding frame 3 through the pushing cylinder 91 and the pushing block 9.

[0036] Further, the receiving part 7 is provided with a limiting groove 71 corresponding to the metal shaft 1, the limiting groove 71 is arranged along the direction from the feeding end to the discharging end of the receiving part 7, the stability of the metal shaft 1 entering the receiving part 7 is improved, and the metal shaft 1 on the receiving part 7 will not affect the normal leaving of the receiving part 7 due to deviation.

[0037] Further, the receiving part 7 is provided with a limiting groove 71 corresponding to the metal shaft 1, the limiting groove 71 is arranged along the direction from the feeding end to the discharging end of the receiving part 7, the stability of the metal shaft 1 entering the receiving part 7 is improved, and the metal shaft 1 on the receiving part 7 will not affect the normal leaving of the receiving part 7 due to deviation.

[0038] Further, the receiving part 7 is provided with a limiting groove 71 corresponding to the metal shaft 1, the limiting groove 71 is arranged along the direction from the feeding end to the discharging end of the receiving part 7, the stability of the metal shaft 1 entering the receiving part 7 is improved, and the metal shaft 1 on the receiving part 7 will not affect the normal leaving of the receiving part 7 due to deviation.

[0039] Further, the receiving part 7 is provided with a limiting groove 71 corresponding to the metal shaft 1, the limiting groove 71 is arranged along the direction from the feeding end to the discharging end of the receiving part 7, the stability of the metal shaft 1 entering the receiving part 7 is improved, and the metal shaft 1 on the receiving part 7 will not affect the normal leaving of the receiving part 7 due to deviation.

[0040] The working process of the utility model is as follows:

[0041] Firstly, as shown in Figure 9 , Figures 1-9 , the material blocking cylinder 101 controls the material blocking rod 10 to open the discharging end of the receiving part 7, and the metal shaft 1 enters the receiving plate 8 from the discharging end of the receiving part 7.

[0042] Then, as shown in Figure 4 ,Figure 5 As shown, the blocking cylinder 101 controls the blocking rod 10 to close the discharge end of the receiving portion 7, and the pushing block 9 pushes the metal shaft 1 away from the discharge end of the receiving plate 8 under the action of the pushing cylinder 91;

[0043] Next, see Figure 6 、 Figure 7 、 Figure 1 , the metal shaft 1 enters the feeding frame 3;

[0044] Then, if Figure 8 As shown, the driving cylinder 62 drives the push rod 6 to extend and sequentially push the movable support plate 2 and the feed frame 3 toward the milling cutter assembly 11 through the outer transmission part 61 and the inner transmission part 21 until the movable support plate 2 and the feed frame 3 move to the preset position and the driving cylinder 62 stops driving the push rod 6 to extend;

[0045] Finally, if Figure 9 Figure 2 Figure 3 As shown, the feeding cylinder 51 causes the feeding rod 5 to extend toward the milling cutter assembly 11 , and the feeding rod 5 pushes the metal shaft 1 to the milling cutter assembly 11 for processing.
