Description

Technical Field

[0001] This utility model relates to the field of industrial machinery technology, specifically to a milling device for shovel-tooth radiators. Background Technology

[0002] The fin milling machine is a special equipment used to process finned radiators. It uses a milling process to cut fins with standard spacing, a certain thickness and height from a whole substrate (such as aluminum or copper) to form a radiator.

[0003] Existing milling fixtures for toothed radiators have relatively limited tooling options for clamping blanks of a single shape. If irregularly shaped blanks need to be clamped, the fixture position must be changed, and tool resetting is required after each change. For ring-shaped blanks requiring inner diameter machining, the tooling fixture needs to be reconfigured. In batch processing at the factory, manual material loading may result in misaligned tooling fixtures, leading to tool collisions, increasing tool costs and safety hazards. Therefore, we need to propose a new milling device for toothed radiators. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a milling device for a toothed radiator, comprising a mounting plate, wherein the mounting plate is provided with a positioning mechanism for self-positioning of the tooling fixture.

[0006] The top of the mounting plate is provided with an inner diameter clamping mechanism for clamping the annular blank.

[0007] The mounting plate is equipped with clamping mechanisms for clamping tooling fixtures on its exterior and top.

[0008] Preferably, the positioning mechanism includes a limiting groove, which is formed at the four corners of the upper and lower sides of the mounting plate. A positioning groove is formed between the upper and lower sets of the limiting grooves. A positioning pin is slidably inserted into the positioning groove.

[0009] Preferably, the inner diameter clamping mechanism includes a base, which is detachably mounted on the top of the mounting plate. The base has a mounting hole at the center, a guide rail is provided at the bottom of the mounting hole, a slider is slidably mounted on the guide rail, and a limiting mechanism is mounted on the top of the slider.

[0010] Preferably, the limiting mechanism includes a first electric cylinder mounted on the top of the slider, a clamping block mounted on the output end of the first electric cylinder, a second electric cylinder disposed inside the base, a buckle mounted on the output end of the second electric cylinder, a slot corresponding to the buckle being opened on the side of the clamping block near the second electric cylinder, the outer wall of the buckle being slidably mounted on the inner wall of the slot, and a detachable top plate disposed on the top of the base.

[0011] Preferably, the clamping mechanism includes a third electric cylinder, which is disposed outside the mounting plate. A first clamping plate is installed at the output end of the third electric cylinder. A fourth electric cylinder is disposed on the top of the mounting plate, and a second clamping plate is installed at the output end of the fourth electric cylinder.

[0012] Preferably, the mounting plate has drainage holes inside, which are located below the mounting holes and away from the guide rail.

[0013] Preferably, the third electric cylinder and the first clamping plate correspond to the mounting plate, and the fourth electric cylinder and the second clamping plate correspond to the top plate.

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

[0015] This invention improves the accuracy of tooling placement during mass production by incorporating a positioning mechanism, reducing the number of tool settings required for the same batch of production. It also prevents tool collisions caused by misaligned tooling, thus reducing tool costs and safety issues.

[0024] 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.

[0025] Please see Figure 1-7 This utility model provides a technical solution: a milling device for a toothed radiator, including a mounting plate 1. The mounting plate 1 has a positioning mechanism inside for self-positioning of the tooling fixture. The positioning mechanism includes limiting grooves 20, which are located at the four corners of the upper and lower sides of the mounting plate 1. A positioning groove 2 is formed between the upper and lower limiting grooves 20. A positioning pin 4 is slidably inserted into the positioning groove 2. Limiting rings 3 are rotatably installed on both the upper and lower sides of the limiting groove 20. The two ends of the positioning pin 4 slide into the interior of the limiting ring 3. The surface of the positioning pin 4 is provided with external threads and is connected and fixed to the threaded holes on the surface of the milling machine's work platform. If the hole on the milling machine does not match the positioning groove 2, an adjustable limiting ring 3 can be set to correspond to the position of the positioning pin 4. The limiting groove 20 is used to limit the movement range of the limiting ring 3. The positioning groove 2 and the limiting ring 3 form a mounting groove for the positioning pin 4. The positioning pin 4 has a tapered design, which facilitates self-positioning of the tooling fixture in mass production. This avoids the problem of tooling misalignment and tool collision that may occur when manually feeding materials, reducing the cost of damaged tools and preventing safety issues caused by tool collisions.

[0026] The top of the mounting plate 1 is equipped with an inner diameter clamping mechanism for clamping an annular blank. The inner diameter clamping mechanism includes a base 5, which is detachably mounted on the top of the mounting plate 1. The base 5 has a mounting hole 6 at its axis, and a guide rail 7 is located at the bottom of the mounting hole 6. A slider 8 is slidably mounted on the guide rail 7, and a limiting mechanism is mounted on the top of the slider 8. The limiting mechanism includes a first electric cylinder 9, which is mounted on the top of the slider 8. A clamping block 10 is mounted on the output end of the first electric cylinder 9. A second electric cylinder 11 is located inside the base 5, and a buckle 12 is mounted on the output end of the second electric cylinder 11. A slot 13 corresponding to the buckle 12 is located on the side of the clamping block 10 near the second electric cylinder 11. The outer wall of the buckle 12 is slidably mounted on the inner wall of the slot 13. A detachable top plate 14 is located on the top of the base 5. A drainage hole 19 is located inside the mounting plate 1, below the mounting hole 6 and away from the guide rail 7. When clamping the annular blank material, the inner hole of the annular blank is placed above the mounting hole 6, with the center of the annular blank material corresponding to the center of the mounting hole 6 for easy clamping. The output end of the second electric cylinder 11 retracts, pulling the buckle 12 to move. The engagement of the buckle 12 and the slot 13 pulls the clamping block 10 to move. The clamping block 10 is installed at the output end of the first electric cylinder 9, which is installed on top of the slider 8. Therefore, when the output end of the second electric cylinder 11 retracts, it will drive the clamping block 10 to move along the guide rail 7. The four clamping blocks 10 evenly clamp the inner diameter of the annular blank material to limit its lateral movement. The output end of the first electric cylinder 9 retracts, causing the clamping block 10 to descend. The upper part of the clamping block 10 is provided with protruding claws to limit the longitudinal movement of the annular blank material. This allows for a more secure clamping of the annular blank material for processing, improving processing accuracy and yield.

[0027] The mounting plate 1 is equipped with clamping mechanisms for clamping tooling fixtures on both its exterior and top. These clamping mechanisms include a third electric cylinder 15, which is located on the exterior of the mounting plate 1. A first clamping plate 16 is mounted on the output end of the third electric cylinder 15. A fourth electric cylinder 17 is located on the top of the mounting plate 1, and a second clamping plate 18 is mounted on the output end of the fourth electric cylinder 17. The third electric cylinder 15 and the first clamping plate 16 correspond to the mounting plate 1, while the fourth electric cylinder 17 and the second clamping plate 18 correspond to the top plate 14. Both the third electric cylinder 15 and the locating pin 4 are mounted on the milling machine's work platform. When clamping ordinary blank materials and irregularly shaped materials, an internal diameter clamping mechanism is not required. Mounting plate 1 is placed on the milling machine's work platform via a positioning mechanism. The output end of the third electric cylinder 15 retracts, driving the first clamping plate 16 to fix mounting plate 1. The blank material is placed on the surface of mounting plate 1, and its position is adjusted so that the edge of the blank material corresponds to the fourth electric cylinder 17. Then, the output end of the fourth electric cylinder 17 retracts, pulling the second clamping plate 18 to press the blank material. This allows for the clamping of various blank materials, reducing the cost of purchasing multiple tooling fixtures.

[0028] 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.
