Description

Technical Field

[0001] The utility model relates to the technical field of double-gantry corner milling equipment, in particular to a straight-row side-mounted tool magazine mechanism. Background Art

[0002] The busbar is the name of the conductive material on the power distribution equipment. It is made of flat copper (equivalent to electric wire) without an insulating layer. The outside is painted with color paint indicating the phase sequence or covered with sleeves of corresponding colors. It is mainly used to connect indoor transformers to distribution cabinets, then to the main power switch, and then to each sub-switch.

[0003] The mainstream processing method in the industry is to use double gantry milling equipment to chamfer (round corners) the busbar row. The straight side-mounted tool magazine mechanism meets the tools required by the equipment. At present, the method with relatively high spindle tool change accuracy is: the tool holder does not move, and the spindle moves to change the tool, such as the gantry busbar row milling equipment disclosed in patent CN219924666U. Although this tool change method improves the tool head installation accuracy, the tool change efficiency needs to be improved. Utility Model Content

[0004] The utility model aims to solve the above-mentioned deficiencies in the prior art and provides a straight-row side-mounted tool magazine mechanism, which adopts the dual-movement mode of tool holder and spindle to change tools, replacing the current mode in which the tool holder does not move but only the spindle moves, thereby speeding up the tool change speed, saving time, improving the tool change efficiency, and ensuring the tool change accuracy.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] Preferably, the ends of the two tool holders are connected via a connecting plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model adopts the dual movement of the tool holder and the spindle to change the tool, replacing the current method in which the tool holder does not move and only the spindle moves, thereby speeding up the tool change speed, saving time, improving the tool change efficiency, and ensuring the tool change accuracy; in addition, a protective cover is arranged on the outside of the tool holder to protect the tool head and improve the operation safety.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 3 As shown, a straight-row side-mounted tool magazine mechanism includes a base 4 and a tool holder 7. Figure 5 As shown, there are two tool holders 7, and the ends of the two tool holders 7 are connected by a connecting plate 702. The two tool holders 7 are located in a straight line, and tool clamps 701 are evenly arranged on each tool holder 7. One tool holder 7 corresponds to one spindle, and the safety distance between the two spindles is controlled by the connecting plate 702 to ensure the safety of tool changing.

[0026] like Figure 4 As shown, the upper end of the base 4 is provided with a motor 6, which is a servo motor 6. A lead screw 602 is connected to the output shaft of the motor 6, and a nut seat 601 is matched with the lead screw 602. The nut seat 601 is connected to the tool holder 7 through a driving plate 603. The upper end of the base 4 is provided with a second guide rail 402, and the lower end of the tool holder 7 is provided with a second slider 703 matched with the second guide rail 402. The tool holder 7 is driven to move by the motor 6.

[0027] like Figure 1 As shown, a protective cover 1 is provided at the upper end of the base 4, and two tool changing ports 101 corresponding to the tool holder 7 are provided on the side wall of the protective cover 1. The middle part of the protective cover 1 is connected to the base 4 through a fixing plate 403 to ensure the stability of the protective cover 1.

[0028] The outer side of the protective cover 1 is covered with a movable cover 2 for shielding the knife-changing port 101. The width of the movable cover 2 is greater than the width of the knife-changing port 101. Figure 2 As shown, a cylinder 5 and a first guide rail 401 are fixed to one side of the protective cover 1, and the piston rod of the cylinder 5 is connected to a push-pull block 501 fixed to the side wall of the movable cover 2. The push-pull block 501 cooperates with the first guide rail 401 through a first slider 502, and the opening and closing of the movable cover 2 are realized through the cylinder 5.

[0029] When the movable hood 2 moves, it sags due to gravity, and the movable hood 2 is not flexible in movement due to the single force. For this reason, a transition bracket 3 connected to the base 4 is provided below the tool changing port 101, and the end of the movable hood 2 away from the cylinder 5 is supported by the transition bracket 3, so as to improve the flexibility and smoothness of the movable hood 2 when moving.

[0030] Tool changing process:

[0031] 1. When the device receives a tool change signal, the motor 6 drives the lead screw 602 to operate according to the PLC instruction, and the lead screw 602 transports the required tool to the tool change port 101 through the nut 601 and the drive plate 603;

[0032] 2. The cylinder 5 moves to open the movable cover 2, exposing the tool change port 101, waiting for the spindle to change the tool. The spindle moves to the tool change port 101 to change the tool;

[0033] 3. After the tool change is completed, the cylinder 5 drives the movable cover 2 to retreat and close the tool change port 101;

[0034] 4. The servo motor 6 drives the lead screw 602 to operate, and moves the tool holder 7 to the coordinate origin to wait.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
