Description

Technical Field

[0001] The utility model belongs to the technical field of positioning jigs, and in particular relates to a positioning jig for locking screws of products of different sizes. Background Art

[0002] In industrial production, screw locking is a common and critical operation to ensure the fastening and stability between different parts. However, when screwing two different products, the existing screw locking positioning fixtures often cannot meet such diverse needs.

[0003] First, the inability to simultaneously lock the upper and lower products results in reduced production efficiency, as operators need to frequently change jigs or manually adjust the screw positions, which increases operation time and costs. Second, manual adjustment of the screw position often results in errors, which may result in loose screw locking or inaccurate position, thus affecting product quality and stability.

[0004] Existing screw locking and positioning jigs often lack flexibility and adjustability when adapting to different products. The structure and size of the jig are fixed and cannot be quickly adjusted according to product changes. This limits the flexibility of the production line and makes it difficult for companies to adapt to the rapid changes in market demand. Utility Model Content

[0005] The purpose of the utility model is to propose a screw locking positioning fixture for products of different sizes in order to solve the problem that the existing screw locking positioning fixtures for upper and lower products cannot be applied to products of various sizes and lack flexibility and adjustability.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solution: a positioning fixture for locking screws of products of different sizes, comprising:

[0007] A mounting plate, wherein a plurality of fixing holes are provided on the mounting plate;

[0008] A limit frame, wherein the limit frame is connected to the mounting plate, the limit frame is provided with a plurality of first connecting holes, the limit frame is provided with a first limiting groove and a second limiting groove, a plurality of first limiting plates are located in the first limiting groove, a plurality of second limiting plates are located in the second limiting groove, a second connecting hole is provided on the first limiting plate, a third connecting hole is provided on the second limiting plate, and the first limiting plate and the second limiting plate are respectively connected to the first limiting groove and the second limiting groove through pins.

[0009] As a further description of the above technical solution:

[0010] The height of the first limiting groove is higher than the height of the second limiting groove.

[0011] As a further description of the above technical solution:

[0012] The first connection hole passes through the top of the limiting frame and extends to the bottom of the first limiting groove and the bottom of the second limiting groove respectively.

[0013] As a further description of the above technical solution:

[0014] The first limiting plate and the second limiting plate are perpendicular to each other and are arranged crosswise in an up-and-down direction.

[0015] As a further description of the above technical solution:

[0016] The limiting frame is provided with threaded holes around it, the bottom of the mounting plate is provided with a mounting hole, and the screws pass through the mounting holes and extend into the threaded holes.

[0017] As a further description of the above technical solution:

[0018] The mounting hole is a countersunk hole.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0020] In the utility model, a limit frame is installed on a mounting plate by setting, wherein the limit frame is provided with a first limit slot located vertically at the bottom, and a second limit slot located horizontally at the top, wherein the first limit plate is movable in the first limit slot, and the second limit plate is movable in the second limit slot. When it is necessary to tighten the screws of the upper and lower products, the bottom product is placed on the mounting plate, and the first limit plate is moved to limit its two sides, and the pin is passed through the fixing hole and the second connecting hole to position it, and then the positioning product is placed, and the second limit plate is moved to limit its two ends, and the pin is passed through the fixing hole and the third connecting hole to position the top product, and then the upper and lower products are screwed and locked. This structure not only has flexibility and adjustability, but also ensures the accuracy of screw tightening.

[0021] In the utility model, this structure is not only suitable for locking upper and lower products, but also for screw locking of a single product. The height of a single product is higher than the first limit plate and lower than the second limit plate. It can accurately position the bottom and top of a single product and improve the accuracy of screw locking. This structure has strong applicability. BRIEF DESCRIPTION OF THE DRAWINGS
