Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a special jig for reducing product deformation. Background Technique

[0002] At present, many electronic products need to be stamped into shape. However, for many stamped products, the material is relatively soft. When the upper die of the stamping equipment presses downward, the stamped material often deforms. Due to the high precision requirements for electronic products in various fields, many defective products are produced, resulting in an increase in production costs. Content of the Utility Model

[0003] The purpose of the utility model is to provide a special jig for reducing product deformation, so as to solve the problem that the stamped material often deforms when the upper die of the stamping equipment presses downward, as mentioned in the above background technique. Due to the high precision requirements for electronic products in various fields, many defective products are produced, resulting in an increase in production costs.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: a special jig for reducing product deformation, including a base. A number of connecting seats are installed on the base, and a product mold is clamped on the connecting seats. A servo motor is installed inside the base, and a transmission gear is connected to the output shaft of the servo motor. The transmission gear is rotatably connected inside the base. Both sides of the transmission gear are engaged with racks. The two racks are perpendicular to the base, and moving plates are installed on both racks. The moving plates are slidably connected to the base, and a number of limiting blocks are installed on one side of the two moving plates close to each other. The limiting blocks on each moving plate correspond to the connecting seats.

[0005] Preferably, a cavity is opened inside the base, and the transmission gear and the racks are both arranged inside the cavity.

[0006] Preferably, a connecting plate is installed on the cavity, and a connecting hole is opened on the connecting plate. The connecting hole, the transmission gear, and the center of the servo motor are on the same axis.

[0007] Preferably, limiting strips are installed on both racks, and two limiting grooves are opened on the connecting plate. The limiting grooves are adapted to the limiting strips.

[0008] Preferably, connecting blocks are installed between the two racks and the corresponding moving plates.

[0009] Preferably, two connecting grooves are opened on the base. The two connecting grooves are communicated with the cavity and are adapted to the corresponding connecting blocks.

[0010] Preferably, the widths of a number of the limiting blocks are greater than the widths of the surfaces in contact with the product mold.

[0011] The beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the product mold is placed on the corresponding connecting seat, and then the servo motor is turned on. The operation of the servo motor drives the transmission gear to rotate synchronously, so that the two racks meshing with the servo motor move towards the position where the product mold is located. Furthermore, the movement of the racks drives the two moving plates and a plurality of limit blocks installed on the two moving plates to approach the product mold synchronously and contact the connecting seat. Thus, the product mold is restricted on the connecting seat by the limit blocks, thereby completing the precise positioning of the product mold, avoiding the situation that the mold is deformed due to material offset during stamping, further improving the cost rate and reducing the production cost.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figures 1-4, A special fixture for reducing product deformation, including a base 1, characterized in that: a number of connecting seats 2 are installed on the base 1, a product mold 3 is clamped on the connecting seat 2, a servo motor 4 is installed inside the base 1, a transmission gear 5 is connected to the output shaft of the servo motor 4, the transmission gear 5 is rotatably connected inside the base 1, racks 6 are meshed on both sides of the transmission gear 5, the two racks 6 are perpendicular to the base 1, and moving plates 7 are installed on both racks 6, the moving plates 7 are slidably connected to the base 1, and a number of limiting blocks 8 are installed on the sides of the two moving plates 7 close to each other, and the limiting blocks 8 on each moving plate 7 correspond to the connecting seat 2.

[0020] When using this fixture, first place the product mold 3 on the corresponding connecting seat 2, and then turn on the servo motor 4. The operation of the servo motor 4 drives the transmission gear 5 to rotate synchronously, so that the two racks 6 meshed with the servo motor 4 move towards the position where the product mold 3 is located. Furthermore, the movement of the racks 6 drives the two moving plates 7 and a number of limiting blocks 8 installed on the two moving plates 7 to approach the product mold 3 synchronously and contact the connecting seat 2. Thus, the product mold 3 is restricted on the connecting seat 2 by the limiting blocks 8, thereby completing the precise positioning of the product mold 3, avoiding the situation that the mold is deformed due to material offset during stamping, and further improving the cost rate and reducing the production cost.

[0021] Specifically, in this embodiment, a cavity 9 is opened inside the base 1, and the transmission gear 5 and the racks 6 are both arranged inside the cavity 9, so that the transmission gear 5 and the racks 6 can be connected to the base 1 through the cavity 9, thereby preventing the transmission gear 5 and the racks 6 from being exposed outside the fixture and causing injury to personnel, and at the same time providing protection for the transmission gear 5 and the racks 6, and further extending the service life of the fixture.

[0022] Specifically, in this embodiment, a connecting plate 10 is installed on the cavity 9, a connecting hole 11 is opened on the connecting plate 10, and the connecting hole 11 is on the same axis as the centers of the transmission gear 5 and the servo motor 4, so that the servo motor 4 can be connected to the transmission gear 5 through the connecting hole 11, and at the same time, the connecting plate 10 provides an installation basis for the servo motor 4, facilitating subsequent power transmission.

[0023] Specifically, in this embodiment, limiting strips 12 are installed on both racks 6, and two limiting grooves 13 are opened on the connecting plate 10. The limiting grooves 13 are adapted to the limiting strips 12, so that the two racks 6 can be slidably connected to the connecting plate 10 through the adaptability of the limiting grooves 13 and the limiting strips 12, thereby providing a guiding effect for the moving direction of the racks 6 through the limiting grooves 13 and preventing the moving direction of the racks 6 from deviating.

[0024] Specifically, in this embodiment, connection blocks 15 are installed between the two racks 6 and the corresponding moving plates 7, enabling the moving plates 7 to be connected to the racks 6 through the connection blocks 15, so that when the racks 6 move, they can drive the moving plates 7 to move synchronously.

[0025] Specifically, in this embodiment, two connection grooves 14 are formed in the base 1. The two connection grooves 14 communicate with the cavity 9 and are adapted to the corresponding connection blocks 15, enabling the connection blocks 15 to be connected to the moving plates 7 via the connection grooves 14. At the same time, when the racks 6 drive the moving plates 7 to move, the connection grooves 14 can provide sufficient moving distance to meet the moving requirements of the moving plates 7.

[0026] Specifically, in this embodiment, the widths of several limiting blocks 8 are greater than the widths of their contact surfaces with the product mold 3, so that the product mold 3 can be firmly restricted between the limiting blocks 8 and the corresponding connection seats 2, preventing the product mold 3 from falling off the jig. At the same time, the connection stability of the product mold 3 on the jig is improved, further enhancing the stability during stamping.

[0027] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
