Description

Technical Field

[0001] This utility model belongs to the field of workpiece assembly technology, and specifically relates to a bracket screw assembly fixture. Background Technology

[0002] When assembling specific products, it is necessary to use, such as Figure 1 The bracket screw 1 shown requires a ring 5 to be fitted onto it, and holes need to be drilled in both the ring 5 and the bracket screw 1. The drill bit must penetrate both the ring 5 and the main body of the bracket screw 1 sequentially. Because it is a steel component, the stress during drilling is high. To prevent the ring 5 from moving and causing the hole position to shift, at least two limiting bolts 3 need to be threaded onto the threaded section 2 of the bracket screw 1. However, due to the lack of dedicated assembly tools for the limiting bolts 3, tightening them requires using two wrenches to clamp each limiting bolt 3. When tightening or loosening the two limiting bolts 3, due to the lack of a fixed point and the bidirectional force, the adjustable wrenches often come loose, causing the product to fall off and deform, and potentially injuring workers. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects in the existing technology and provide a bracket screw assembly tool.

[0004] This utility model provides a bracket screw assembly fixture for fixing bracket screws. One end of the bracket screw has a threaded section, and the other end has a square head. The diameter of the threaded section is smaller than the diameter of the bracket screw body, and a ring is fitted on the threaded section. At least two limiting nuts are provided on the outside of the ring to fix the ring. The assembly fixture includes a fixture body, which is detachably mounted on a lathe by fixing bolts. A slot is provided in the fixture body, and the square head is inserted into the slot to fix the bracket screw. Both ends of the fixture body have U-shaped grooves. One end of the fixing bolt is engaged with the lathe, and the other end of the fixing bolt passes through the U-shaped groove and is fixed with a nut.

[0005] A further embodiment is that the slot includes a recessed circular groove and a square groove, the recessed circular groove being formed on the surface of the tooling body, and the square groove being formed on the surface of the recessed circular groove.

[0006] A further embodiment is that the card slots are provided in several ways, and the recessed circular grooves and square grooves of different card slots have different sizes.

[0007] A further embodiment is that several convex plates are arranged side by side on the lathe, and a gap is reserved between two adjacent convex plates to form a groove; One end of the fixing bolt engages with the groove, and the other end of the fixing bolt passes through the U-shaped groove and is secured with a nut.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a slot on the tooling body to insert and secure the square head of the bracket screw, effectively preventing the bracket screw from rotating or moving when tightening or loosening the limit nut, thus avoiding product detachment, deformation, and worker injury. The tooling body is detachably mounted on the lathe via fixing bolts and a U-shaped groove, facilitating installation and disassembly. The U-shaped groove design allows the fixing bolts to be adjusted within a certain range, adapting to the groove structure of the lathe, enhancing the tooling's applicability and flexibility.

[0009] The tooling body of this invention is equipped with multiple slots of different sizes to accommodate bracket screws of different specifications, thereby improving the versatility and work efficiency of the tooling. The tooling body adopts a rectangular plate structure, combined with the cooperation of recessed circular slots and square slots, to ensure that the bracket screws are firmly fixed, making operation simple, reducing assembly time and improving assembly accuracy.

[0011] To make the objectives, technical solutions, design methods, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0012] This utility model provides a bracket screw assembly fixture for assembling bracket screw 1, specifically, as follows: Figure 1As shown, one end of the bracket screw 1 has a threaded section 2, and the diameter of the threaded section 2 is smaller than the diameter of the bracket screw 1. A ring 5 can be fitted onto the threaded section 2, allowing one end of the ring 5 to abut against the bracket screw 1. The other end of the bracket screw 1 has a square head 4. Drilling is required simultaneously on both the ring 5 and the threaded section 2; that is, a drill bit is used to drill through the ring 5 and the threaded section 2 sequentially. Since both the ring 5 and the threaded section 2 are rigid, two limiting nuts 3 need to be installed on the outside of the ring 5 to prevent displacement. The limiting nuts 3 are installed with the assistance of assembly fixtures. Figure 2 As shown, the assembly fixture includes a fixture body 11, which is detachably mounted on a lathe 16 via fixing bolts 13. A slot is provided in the fixture body 11, into which the square head 4 is inserted to fix the bracket screw 1. U-shaped grooves 12 are provided at both ends of the fixture body 11. One end of the fixing bolt 13 engages with the lathe 16, and the other end of the fixing bolt 13 passes through the U-shaped groove 12 and is secured with a nut. In this embodiment, the fixture body 11 is a rectangular plate of 192mm × 47mm and 20mm thick. A U-shaped groove 12 is provided at the center of each of the two short sides of the rectangular plate. The U-shaped groove is 12mm wide, 33mm long, and has a bottom corner radius of 5mm. Figure 3 As shown, to ensure the square head 4 remains stable after being inserted into the slot, the slot includes a recessed circular groove 18 and a square groove 19. The recessed circular groove 18 is formed on the surface of the tooling body 11, and the square groove 19 is formed on the surface of the recessed circular groove 18. To accommodate bracket screws 1 of different sizes, several slots are provided in this embodiment, and the recessed circular groove 18 and square groove 19 of different slots have different dimensions. Specifically, the tooling body 11 includes a first slot 14 and a second slot 15: the first slot 14 has a 7mm×7mm square groove with a depth of 12mm, and a circular countersunk hole with a diameter of 11mm and a depth of 1.7mm is formed with the center point of the square as the center; the second slot 15 has a 10mm×10mm square groove with a depth of 14mm, and a circular countersunk hole with a diameter of 16mm and a depth of 3.5mm is formed with the center point of the square as the center.

[0013] like Figure 4 As shown, in order to ensure that the tooling body 11 is fixedly connected to the lathe 16, multiple convex plates 17 are arranged side by side on the lathe 16, and a gap is reserved between two adjacent convex plates 17 to form a groove; one end of the fixing bolt 13 is engaged with the groove, and the other end of the fixing bolt 13 passes through the U-shaped groove 12 and is fixed with a nut.

[0014] like Figure 5As shown, when assembling component B8 onto component A7, a bracket screw 1 is required. Component A7 has a through hole through which the bracket screw 1 passes. The ring 5 is then fitted onto the threaded section 2. A pin is then inserted through the ring 5 and the pin hole 6 on the bracket screw 1. The position of the ring 5 is then fixed by chiseling the ends of the pin with a steel chisel. Disassembly only requires replacing the pin. A threaded hole is provided on component B8, allowing the threaded section 2 of the bracket screw 1 to be screwed in to complete the assembly. The cooperation of the ring 5 and the pin ensures the flatness requirements of multiple components B8.

[0015] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical applications, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
