Description

Technical Field

[0001] This utility model relates to the field of handling fixture technology, specifically a multi-size die-casting part handling fixture. Background Technology

[0002] Die casting is a process where a pressure casting machine equipped with a casting mold pours molten metal (such as copper, zinc, aluminum, or aluminum alloys) into the machine's feed inlet, and the resulting part has a specific shape and size. This process can produce parts with complex shapes, thin walls, high precision, smooth surfaces, and high dimensional consistency. After production, die castings typically need to be moved from one location to another using handling fixtures. Die casting handling fixtures are specially designed tools for handling die castings, improving handling efficiency and ensuring the safety and integrity of the die castings during transport.

[0003] Existing die-casting part handling fixtures can usually only hold and fix die-casting parts of a specific size within a certain range. When the die-casting parts to be handled have large differences in size or shape, the clamping heads need to be replaced on-site to ensure stable clamping. This results in additional time being spent changing the clamps when switching products, increasing the labor intensity of personnel, and may even bring potential risks during the replacement process. Therefore, to address the above problems, a multi-size die-casting part handling fixture is proposed. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a multi-size die-casting part handling fixture. This fixture includes two clamping structures: several small adjustable jaws and one large jaw. The small adjustable jaws are used to clamp small-sized die-casting parts, while the large jaw is used to clamp large-sized die-casting parts. Furthermore, the small adjustable jaws can adjust their clamping shape within a certain range. In summary, this handling fixture can adapt to clamping and fixing products of different sizes and shapes over a wide range, eliminating the need for workers to spend extra time changing jaws when switching between products. This reduces the labor intensity of workers, avoids potential risks during the replacement process, and solves the technical problem in the prior art where, when the dimensions or shapes of the die-casting parts being handled differ significantly, it requires considerable time to change the clamping heads on-site, potentially leading to risks during the replacement process.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A multi-size die-casting part handling fixture includes a mounting base with a fixture bracket fixedly mounted at its front end, and a connecting frame for connecting to an external drive structure fixedly mounted on the bracket. Several small adjustable grippers are mounted on the lower end face of the fixture bracket for clamping and fixing small-sized die-casting parts. A large gripper is fixedly mounted on the rear end face of the mounting base for clamping and fixing large-sized die-casting parts. This handling fixture includes two clamping structures: several small adjustable grippers and one large gripper. The small adjustable grippers are used to clamp small-sized die-casting parts, and the large gripper is used to clamp large-sized die-casting parts. The small adjustable grippers can adjust their clamping shape within a certain range. In summary, this handling fixture can adapt to clamping and fixing products of different sizes and shapes over a wide range, eliminating the need for workers to spend extra time changing grippers when switching products, reducing worker labor intensity, and avoiding potential risks during the changeover process.

[0007] In one possible implementation, the small-sized adjustable gripper includes a first bidirectional drive cylinder on which a first L-shaped clamping plate and a second L-shaped clamping plate are mounted. The cylinder is used to drive the first L-shaped clamping plate and the second L-shaped clamping plate to move synchronously closer or further away. Based on the above structure, the first bidirectional drive cylinder is used to drive the first L-shaped clamping plate and the second L-shaped clamping plate to move, thereby clamping or releasing the die-casting part.

[0008] In one possible implementation, the bottom of the first L-shaped clamping plate is provided with several threaded adjustment holes, and the bottom of the second L-shaped clamping plate is machined to form several forked heads, and each forked head is provided with a threaded adjustment hole at its bottom. The above structure provides the necessary structural basis for adjusting the clamping size.

[0009] In one possible implementation, a threaded clamping screw passes through the threaded adjustment hole. A contact is fixedly provided at the inner end of the clamping screw. When the clamping screw is turned, the position of the contact can be adjusted accordingly, thereby adjusting the positional relationship between the contacts so that they can fit against the outer edge of each product, improving the clamping stability and making it suitable for clamping die-cast parts of different shapes.

[0010] In one possible implementation, the large-size gripper includes a mounting base plate on which a second bidirectional drive cylinder is mounted. The second bidirectional drive cylinder is mounted with two symmetrically arranged U-shaped clamping plates. Anti-slip gripping heads are fixedly mounted at the ends of the U-shaped clamping plates. The second bidirectional drive cylinder is used to drive the U-shaped clamping plates to move, clamping or releasing the die-casting part. The anti-slip gripping heads can increase the friction between the U-shaped clamping plates and the die-casting part, improving the stability of the clamping.

[0011] In one possible implementation, the anti-slip clamping head includes a mounting shaft with a threaded mounting platform fixedly disposed at its top. A spherical block is mounted in the threaded mounting platform, and a toothed head is fixedly disposed at its top. A locking cover ring is threadedly connected to the threaded mounting platform to press and lock the spherical block. The above structure enables the detachable installation of the spherical block, and the toothed head can increase the friction with the die-casting part and improve the stability of clamping.

[0012] In one possible implementation, the connecting frame includes a connecting rod frame, the outer end of which is fixedly connected to a connecting base plate, and the inner end of which is bolted to the mounting base frame via a fixedly connected connecting flange. The above structure can realize a fixed connection between the mounting base frame and the external drive structure.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] This handling fixture includes two clamping structures: several small adjustable jaws and one large jaw. The small adjustable jaws are used to clamp small die-cast parts, while the large jaw is used to clamp large die-cast parts. The small adjustable jaws can adjust the clamping shape within a certain range. In summary, this handling fixture can adapt to clamping and fixing products of different sizes and shapes over a wide range, eliminating the need for workers to spend extra time changing jaws when switching products, reducing the labor intensity of workers, and avoiding potential risks that may arise during the changeover process.

[0021] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0022] like Figure 1 As shown in the figure, this embodiment provides a multi-size die-casting part handling fixture, including a mounting base 1, a fixture support 2 fixedly mounted at its front end, and a connecting frame 5 fixedly mounted on it for connection with an external drive structure. Several small adjustable grippers 3 are mounted on the lower end face of the fixture support 2 for clamping and fixing small-sized die-casting parts, and a large gripper 4 is fixedly mounted on the rear end face of the mounting base 1 for clamping and fixing large-sized die-casting parts. This handling fixture includes two clamping structures: several small adjustable grippers 3 and a large gripper 4. The small adjustable grippers 3 are used to clamp small-sized die-casting parts, and the large gripper 4 is used to clamp large-sized die-casting parts. The small adjustable grippers 3 can adjust their clamping shape within a certain range. In summary, this handling fixture can adapt to the clamping and fixing of products of different sizes and shapes within a wide range, so that workers do not need to spend extra time changing grippers when switching products, reducing the labor intensity of workers and avoiding potential risks that may arise during the change process.

[0023] like Figure 2 As shown, the small-sized adjustable gripper 3 includes a first bidirectional drive cylinder 31, on which a first L-shaped clamping plate 32 and a second L-shaped clamping plate 33 are mounted. The cylinder is used to drive the first L-shaped clamping plate 32 and the second L-shaped clamping plate 33 to move synchronously closer or further away. Based on the above structure, the first bidirectional drive cylinder 31 is used to drive the first L-shaped clamping plate 32 and the second L-shaped clamping plate 33 to move, thereby clamping or releasing the die-casting part.

[0024] The first L-shaped clamping plate 32 has several threaded adjustment holes 34 at its bottom, and the second L-shaped clamping plate 33 has several forked heads machined at its bottom, with each forked head having a threaded adjustment hole 34 at its bottom. This structure provides the necessary structural basis for adjusting the clamping size. A threaded clamping screw 35 passes through the threaded adjustment hole 34, and a contact 36 is fixedly installed at the inner end of the clamping screw 35. When the clamping screw 35 is turned, the position of the contact 36 can be adjusted accordingly, thereby adjusting the positional relationship between the contacts 36 so that they can fit against the outer edge of each product, improving the stability of clamping and making it suitable for clamping die-cast parts of different shapes.

[0025] like Figure 3 As shown, the large-size gripper 4 includes a mounting base plate 41 on which a second bidirectional drive cylinder 42 is mounted. Two symmetrically arranged U-shaped clamping plates 43 are mounted on the second bidirectional drive cylinder 42. Anti-slip clamping heads 44 are fixedly mounted at the ends of the U-shaped clamping plates 43. The second bidirectional drive cylinder 42 is used to drive the U-shaped clamping plates 43 to move, clamping or releasing the die-casting part. The anti-slip clamping heads 44 can increase the friction between the U-shaped clamping plates 43 and the die-casting part, improving the stability of clamping.

[0026] like Figure 4 As shown, the anti-slip clamping head 44 includes a mounting shaft 441, with a threaded mounting platform 442 fixedly mounted at its top. A spherical block 443 is mounted in the threaded mounting platform 442, and a toothed head 444 is fixedly mounted at its top. A locking cover ring 445 is threaded onto the threaded mounting platform 442, which is used to press and lock the spherical block 443. The above structure allows for the detachable installation of the spherical block 443, and the toothed head 444 on it can increase the friction with the die-casting part and improve the stability of clamping.

[0027] like Figure 1 As shown, the connecting frame 5 includes a connecting rod frame 51, with a connecting base plate 52 fixedly connected to its outer end, and its inner end bolted to the mounting base 1 through a fixed connecting flange 53. The above structure can realize the fixed connection between the mounting base 1 and the external driving structure.

[0028] The working principle and usage process of this utility model:

[0029] This handling fixture includes two clamping structures: several small adjustable jaws 3 and one large jaw 4. The small adjustable jaws 3 are used to clamp small die-cast parts, while the large jaw 4 is used to clamp large die-cast parts. The small adjustable jaws 3 can adjust their clamping shape within a certain range. In summary, this handling fixture can adapt to clamping and fixing products of different sizes and shapes over a wide range. This eliminates the need for workers to spend extra time changing jaws when switching products, reducing the labor intensity of workers and avoiding potential risks that may arise during the changeover process.

[0030] The aforementioned small-sized adjustable gripper 3 has several threaded adjustment holes 34 at its bottom, through which a threaded clamping screw 35 passes. A contact 36 is fixedly installed at the inner end of the clamping screw 35. When the clamping screw 35 is turned, the position of the contact 36 can be adjusted accordingly, thereby adjusting the positional relationship between the contacts 36 so that they can fit against the outer edge of each product, improving the clamping stability and making it suitable for clamping die-cast parts of different shapes. In the aforementioned large-sized gripper 4, the second bidirectional drive cylinder 42 is used to drive the U-shaped clamping plate 43 to move, clamping or releasing the die-cast part. The anti-slip clamping head 44 can increase the friction between the U-shaped clamping plate 43 and the die-cast part, improving the clamping stability.

[0031] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
