Description

Technical Field

[0001] The utility model relates to a machining center component, in particular to a tool magazine of a machining center. Background Art

[0002] A tool magazine of a machining center is a device that provides the tool storage and tool changing requirements during the automated machining process. It can store multiple tools. Under the control of a computer program, the correct tool is selected and positioned, and with the cooperation of a tool changing mechanism, the tool exchange action is realized, and thus various different machining requirements, such as milling, drilling, boring, tapping, etc., can be completed, greatly shortening the machining time and reducing the production cost.

The gear set 30 and the fixed seat 40 are arranged inside the driving box 20. The driving motor 10 extends into the driving box 20 and is connected to the input end of the gear set 30. The outer cover 70 is fixed on the driving box 20. One end of the linkage shaft 50 extends into the driving box 20 and is connected to the output end of the gear set 30. The other end of the linkage shaft 50 extends into the outer cover 70 and is fitted and installed with the bearing plate 100. The positioning shaft 60 passes through the linkage shaft 50 and is fitted and installed with the fixed seat 40. The ejecting mechanism 110 is installed on the positioning shaft 60. Each tool holder 90 corresponds to a group of position adjusting components 80. The tool holder 90 is installed on the bearing plate 100 through the position adjusting components 80. The ejecting mechanism 110 drives the tool holder 90 to rotate and adjust the position through the position adjusting components 80, so that the tool holder 90 extends out of the outer cover 70 or retracts to the initial position.

[0030] The outer cover 70 is provided with a position adjusting port. The bearing plate 100 is integrally arranged in a round cake shape. The circumferential surface of the bearing plate 100 is provided with a plurality of functional holes 101. The bearing plate 100 is provided with positioning strips 103 on both sides of the orifice of the functional hole 101. The functional holes 101 are evenly spaced around the axis of the bearing plate 100. An assembly hole 102 extending inward is further provided inside the functional hole 101.

[0031] The position adjusting component 80 includes a spring 83, a rotating shaft 82 and a limiting seat 81. One side of the limiting seat 81 is provided with a horizontally inward extending clamping groove 811. The other side of the limiting seat 81 is provided with a step. The limiting seat 81 is provided with a first limiting surface 812, a second limiting surface 813 and a third limiting surface 814 at the step position. The first limiting surface 812 and the second limiting surface 813 face outward and have a height difference. The third limiting surface 814 is arranged between the first limiting surface 812 and the second limiting surface 813.

[0032] The tool holder 90 includes a connecting plate 91, a tool holder body 92 connected to one side of the connecting plate 91, two adjusting plates 93 connected to the other side of the connecting plate 91, an adjusting shaft 94 connecting the two adjusting plates 93, and an adjusting wheel 95 installed on the rotating shaft. The two adjusting plates 93 are arranged opposite to each other in the horizontal direction. The connecting plate 91 and the adjusting plates 93 are distributed in an L shape. The side of the adjusting plate 93 facing away from the tool holder body 92 is a first clamping surface 931, and the bottom of the connecting plate 91 is a second clamping surface 911.

[0033] The ejection mechanism 110 includes a driving cylinder 111 and an adjustment frame 112. A piston rod is provided on the driving cylinder 111, and the adjustment frame 112 is connected to the piston rod. Two driving rods 113 are oppositely arranged on the adjustment frame 112. A first functional part 114 and a second functional part 115 are respectively provided on the inner sides of the two driving rods 113. There is a height difference between the first functional part 114 and the second functional part 115. Arc-shaped guiding surfaces are further provided on the inner side surfaces of the first functional part 114 and the second functional part 115. Among them, the guiding surface of the first functional part 114 is inclined downward and inward, and the guiding surface of the second functional part 115 is inclined downward and inward.

[0034] During assembly, the moving direction of the piston rod of the ejection mechanism 110 is opposite to the direction of the adjustment port of the outer cover 70. The limiting seat 81 is inserted into the hole of the bearing plate 100. The clamping groove 811 of the limiting seat 81 is clamped on the bearing plate 100. The spring 83 of the adjustment assembly 80 is installed on the assembly hole 102 and extends out of the assembly hole 102. The spring 83 elastically abuts against the limiting seat 81, and the spring 83 presses the limiting seat 81 in the outward direction. The rotating shaft 82 of the adjustment assembly 80 simultaneously passes through the connecting plate 91 of the tool holder 90 and the positioning strip 103 of the bearing plate 100. The tool holder 90 can rotate around the axis of the rotating shaft 82. The driving motor 10 drives the bearing plate 100 through the gear set 30 and the linkage shaft 50. During the rotation of the bearing plate 100, the tool holder 90 and the adjustment assembly 80 are driven to rotate synchronously. The rotation paths of the adjustment plate 93 and the adjustment wheel 95 on the tool holder 90 are located between the two driving rods 113 of the adjustment frame 112. The adjustment wheels 95 of different tool holders 90 are sequentially moved between the two driving rods 113 of the adjustment frame 112.

[0035] When the tool holder 90 is in the state of being stored in the outer cover 70, the spring 83 presses against the limit seat 81. The first limit surface 812 and the third limit surface 814 of the limit seat 81 are respectively in contact with the first clamping surface 931 and the second clamping surface 911 of the tool holder 90. The limit seat 81 limits the tool holder 90. When it is necessary to cooperate with the tool changing mechanism for tool loading and tool changing, the driving motor 10 adjusts the corresponding tool holder 90 to the position opposite to the adjustment port. The guiding surface of the first functional part 114 is arranged opposite to the adjustment wheel 95 on the tool holder 90. The driving cylinder 111 of the ejecting mechanism 110 drives the adjustment frame 112 to shift towards the adjustment port. During the shifting process of the adjustment frame 112, the guiding surface of the first functional part 114 presses against the adjustment wheel 95, thereby causing the tool holder 90 to flip and adjust its position. The tool holder 90 extends out from the adjustment port until the second limit surface 813 of the limit seat 81 is in contact with the second clamping surface 911 of the tool holder 90. At this time, the guiding surface of the second functional part 115 of the driving rod 113 is arranged opposite to the adjustment wheel 95 on the tool holder 90, and the spring 83 pushes the limit seat 81 to press tightly against the tool holder 90. Conversely, when the tool holder 90 completes tool loading and tool changing, the driving cylinder 111 of the ejecting mechanism 110 drives the adjustment frame 112 to shift away from the adjustment port. The guiding surface of the second functional part 115 presses against the adjustment wheel 95, thereby causing the tool holder 90 to reverse and flip its position, and the tool holder 90 is stored in the outer cover 70.

[0036] The beneficial effects of the tool magazine of the machining center of the present utility model are as follows: By providing the first limit surface 812, the second limit surface 813 and the third limit surface 814 on the limit seat 81 of the adjustment assembly 80, and the first clamping surface 931 and the second clamping surface 911 on the tool holder 90. When the tool holder 90 is in the state of being stored in the outer cover 70, the spring 83 presses against the limit seat 81. The first limit surface 812 and the third limit surface 814 of the limit seat 81 are respectively in contact with the first clamping surface 931 and the second clamping surface 911 of the tool holder 90. The limit seat 81 limits the tool holder 90. When it is necessary to cooperate with the tool changing mechanism for tool loading and tool changing, the spring 83 presses against the limit seat 81. The second limit surface 813 of the limit seat 81 is in contact with the second clamping surface 911 of the tool holder 90. The limit seat 81 limits the tool holder 90, so that when the tool holder 90 cooperates with the tool changing mechanism, it is not easy to shake. The overall cooperation structure is simple, the equipment cost is reduced, it is convenient for maintenance, and the practicability is strong.
