Description

Technical Field

[0001] The utility model relates to the field of fastener processing equipment, in particular to a blind rivet closing positioning and fixing device. Background Art

[0002] Blind rivets, also known as blind rivets, are single-sided rivets that require a specialized tool—a rivet gun (manual, electric, or pneumatic)—to engage. During the riveting process, the gun pulls the mandrel, expanding the rivet body and achieving the desired connection. These rivets are commonly used in connecting special-shaped panels, particularly where conventional rivets (which require riveting from both sides) are inconvenient. Consequently, they are widely used in high-tech fields such as aerospace.

[0003] However, for blind rivets that need to be closed and fixed according to certain product standards, the processing efficiency of the staff is low, and the reliability of the product riveting cannot be guaranteed, resulting in low overall processing efficiency of the blind rivet products.

[0016] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The embodiments described are merely a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0017] The following is combined with Figure 1-3 The specific implementation methods of the present invention are described to facilitate a better understanding of the present invention.

[0018] The present invention provides a blind rivet closing positioning and fixing device, comprising a base 1, a positioning block 2, a cylindrical pin 3, a sleeve 4, and a cover plate 5. The base 1 is provided with a stepped hole 1a at the top; the positioning block 2 is embedded in the stepped hole 1a; the cylindrical pins 3 are multiple rods vertically fixed to the top of the base 1; the cover plate 5 is provided with multiple through holes that are slidably sleeved on the outside of the cylindrical pins 3 in a one-to-one manner; the sleeve 4 is a multiple cylindrical body that is slidably sleeved on the outside of the cylindrical pins 3 in a one-to-one manner and fixed to the bottom of the cover plate 5. A groove 2a is provided at the center of the positioning block 2; a countersunk hole 5a is provided at the center of the cover plate 5; the groove 2a is located directly above the countersunk hole 5a.

[0019] When in use, the positioning block 2 is installed in the stepped hole 1a at the top of the base 1, and the cylindrical pin 3 is installed in the left connecting hole 1b and the right connecting hole 1c at the top of the base 1. First, a sleeve 4 suitable for the length of the blind rivet is selected and sleeved on the cylindrical pin 3. Then, the sleeve 4 is sleeved on the upper part of the cylindrical pin 3 through the left through hole 5b and the right through hole 5c on the cover plate 5, thereby pressing the cover plate 5 on the sleeve 4 and fixing it to the upper part of the cylindrical pin 3. The sleeve 4 can slide up and down along the cylindrical pin 3 with the cover plate 5, forming a complete set of closing and fixing devices. The core rod head of the blind rivet is inserted into the groove 2a on the positioning block 2 through the countersunk hole 5a on the cover plate 5. In this way, the installation position of the blind rivet is fixed by the countersunk hole 5a on the cover plate 5 and the groove 2a on the positioning block 2, which effectively solves the problem of closing and fixing the blind rivet.

[0020] Among them, the blind rivet products of different sizes can be adapted by changing the length of the sleeve 4, the aperture of the cover plate countersunk hole 5a and the diameter of the positioning block groove 2a.
