[0001] This utility model relates to the technical field of tool changing devices, specifically a tool changing device for casting. Background Technology

[0002] The development of casting tool changing devices is closely related to the progress of modern manufacturing technology. With the improvement of industrial automation, especially the application of digital control technology and precision machining technology, tool changing devices can achieve faster and more precise operation, adapt to the needs of different casting products, and at the same time reduce the risks of manual operation and ensure the quality stability of products.

[0003] Current tool changing devices typically include mechanical, hydraulic, or electric systems, enabling rapid and precise replacement of tools on the cutter head. However, tool changing devices used in casting still have some shortcomings in practical applications. For example, existing tools are generally placed in tool slots on the cutter head, which are usually fixed and cannot be replaced. When different sizes of tools need to be placed later, the corresponding cutter head must be replaced, making the operation cumbersome and inconvenient for practical use.

[0004] Therefore, a tool changing device for casting is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a tool changing device for casting, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a casting tool changing device, comprising a housing and a tool changing device body, a tool disc being provided above the housing, a plurality of grooves being formed on one side of the tool disc, an insert block being installed on one side of the inner wall of each of the plurality of grooves, a tool holder being provided inside each of the plurality of grooves, a sliding groove being formed on one side of each of the plurality of tool holders, a first spring being installed on one side of the inner wall of each of the plurality of sliding grooves, a stop block being installed on the other end of each of the plurality of first springs, and the plurality of insert blocks being respectively inserted into the interior of the corresponding sliding grooves, and a slot being formed in the interior of a corresponding set of the tool disc, tool holders and insert blocks, and a limit component being provided inside the interior of each of the plurality of slots.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When different sizes of knives need to be placed, this utility model releases the restriction between the knife holder and the insert block by pulling the limiting shaft out of the slot and inserting it into the groove to the appropriate position. At this time, the second spring pushes the limiting shaft back into the slot for restriction, and the first spring keeps the knife holder firmly fixed in the position. It is easy to operate and convenient for practical use.

[0015] 2. This utility model, through the setting of a moving groove, a guide block, a third spring, and a hollow block, allows the moving cutter head to slide into the interior of the cutter holder along the outer wall of the guide block when changing the cutter. The reaction force of the third spring keeps the cutter head firmly placed inside the cutter holder, thus improving stability when changing the cutter head.

[0016] At the same time, by controlling the rotation of the rotating motor, the drive wheel slides on the gear plate. As it moves, the slider moves on the outer wall of the slide rail, thereby moving the sliders on both sides together.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a casting tool changing device, including a housing 1 and a tool changing device body. A tool disc 3 is provided on the top of the housing 1. A plurality of grooves 4 are formed on one side of the tool disc 3. An insert block 10 is installed on one side of the inner wall of each of the plurality of grooves 4. A tool holder 5 is provided inside each of the plurality of grooves 4. A sliding groove 7 is formed on one side of each of the plurality of tool holders 5. A first spring 8 is installed on one side of the inner wall of each of the plurality of sliding grooves 7. A stop block 9 is installed on the other end of each of the plurality of first springs 8. The plurality of insert blocks 10 are respectively inserted into the inner wall of the corresponding sliding groove 7. The part has slots 11 inside the corresponding set of cutter heads 3, cutter holders 5 and insert blocks 10. Each slot 11 is equipped with a limit component. By pulling the limit shaft 12 and disengaging it from the slot 11, the limit between the cutter holder 5 and the insert block 10 is released, and a new cutter holder 5 is inserted into the groove 4 to the appropriate position. At this time, the limit shaft 12 is pushed back into the slot 11 by the force of the second spring 14 to limit it, and the cutter holder 5 is fixed in the position by the force of the first spring 8. The operation is convenient.

[0024] like Figure 1 and 2 As shown, the tool changing device body includes a spindle 2, the lower end of which is rotatably connected to the top of the housing 1. A drive motor is installed at the lower end of the spindle 2 and is mounted on the housing 1. A tool disc 3 is installed above the spindle wall of the spindle 2. Tool heads 6 are provided on the inner walls of multiple tool holders 5. By controlling the drive motor to drive the spindle 2 to rotate, the tool disc 3 is driven to rotate, thereby changing the tool.

[0025] like Figure 2 and 3 As shown, the limiting assembly includes multiple limiting shafts 12, which are respectively inserted into the interior of corresponding slots 11. Each limiting shaft 12 has a fixing ring 13 installed below its shaft wall, and a second spring 14 is installed at the bottom of each fixing ring 13. The lower ends of the multiple second springs 14 are all mounted on a fixing seat 15, which is mounted on the cutter head 3. The lower ends of the multiple limiting shafts 12 pass through the top of the fixing seat 15 and extend downward. Each limiting shaft 12 has a pull ring 16 installed at its lower end, which allows the limiting shafts 12 to move up and down by moving the pull ring 16.

[0026] like Figure 4 As shown, two movable slots 17 are opened on one side of the inner wall of multiple tool holders 5. Guide blocks 18 are slidably installed inside the multiple movable slots 17. A third spring 19 is installed on one side of the multiple guide blocks 18. A hollow block 20 is installed at one end of the multiple third springs 19. The multiple hollow blocks 20 are respectively installed on the corresponding tool holders 5. When changing tools, the movable tool head 6 slides into the inside of the tool holder 5 along the outer wall of the guide block 18. The reaction force of the third spring 19 makes the tool head 6 stably placed inside the tool holder 5, which makes the stability better when changing the tool head 6.

[0027] The working principle is as follows: In actual use, this utility model allows for the replacement of different cutting tools according to processing requirements. Different tool holders 5 are used to place different specifications of cutting tools. During use, pulling down the pull ring 16 moves the limiting shaft 12 downward, causing it to disengage from the slot 11. This releases the restriction between the tool holder 5 and the insert block 10, allowing the tool holder 5 to be removed along the outer wall of the insert block 10. The new tool holder 5 is then inserted into the appropriate position inside the groove 4. At this point, the second spring 14 pushes the fixing ring 13 upward, which in turn pushes the limiting shaft 12 back into the tool disc 3, the tool holder 5, and the slot 11 for restriction. The first spring 8 pushes the stop block 9 to move along the sliding groove 7, pressing against the insert block 10 inside the sliding groove 7, thus securing the tool holder 5 firmly in that position. The replacement operation is convenient and easy to use.

[0028] Example 2: As Figure 1 and2 As shown, to facilitate the replacement of the cutting tools on the cutter head 3 during actual operation, a base 21 is provided at the bottom of the outer casing 1. Two slide rails 22 are installed on the top of the base 21, and sliders 23 are slidably installed on the outer walls of both slide rails 22. Both sliders 23 are installed on the outer casing 1. A rotary motor 24 is installed on one side of the left slider 23. A drive wheel 25 is installed at the output end of the rotary motor 24. A gear plate 26 is meshed on one side of the drive wheel 25 and is installed on the base 21. By controlling the rotary motor 24 to rotate, the drive wheel 25 is driven to slide on the gear plate 26. While moving, the slider 23 moves on the outer wall of the slide rail 22, thereby moving the sliders 23 on both sides together. This also moves the outer casing 1 and the components above it together, making it convenient to move the cutter head 3 out of the processing device or to the side, so as to facilitate the replacement of the cutting head 6.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
