Description

Technical Field

[0001] This utility model relates to the field of press-fitting fixture technology, specifically a press-fitting fixture for positioning pins on the controller cover. Background Technology

[0002] The controller housing is the physical encapsulation structure of the electronic control system. Its main functions include: protecting internal components from dust, moisture, and shock (IP rating up to IP67); heat dissipation management, using heat conduction path design (such as aluminum substrate + heat sink fins) to dissipate heat from the chip; human-machine interaction: integrating indicator lights, buttons, interfaces, and other operating interfaces; electromagnetic compatibility (EMC), shielding against electromagnetic interference (such as using conductive coatings or shielding layers).

[0003] When pressing parts, the existing controller cover positioning pin pressing fixture requires each part to be paired with the positioning plate on the pressing equipment. During assembly, without limiting the parts, the parts are prone to misalignment with the positioning plate. This can lead to the pressing head being unable to accurately press the pins, tubes, plugs, etc. of the parts, thus reducing the product qualification rate. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning pin clamping fixture for the controller cover to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a controller upper cover positioning pin pressing fixture, including a fixture base plate, and further comprising:

[0006] The upright plate and rib plate are set above the base plate of the fixture. A positioning plate is bolted to one side of each upright plate and rib plate. A lever cylinder is set on the outside of the positioning plate. A pressure head is fixed on the top of the positioning plate.

[0007] Preferably, the upright plate and the rib plate have matching shapes and are made of the same material.

[0008] Preferably, the positioning disk is circular, and the inner diameter of the two positioning disks is the same.

[0009] Preferably, a support column is bolted to the top of the fixture base plate, and the support column is fixed to the bottom of the upright plate and the rib plate.

[0010] Preferably, the outer ring array of the positioning disk is fixed with several positioning pin seats, and each of the positioning pin seats can be fitted with a suitable bolt.

[0011] Preferably, an electric cylinder is fixed to the top of the clamp base plate, and the piston rod of the electric cylinder is detachably mounted on one side of the support column.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention installs the parts to be processed onto the positioning pins on the positioning plate using matched bolts, thus positioning the parts. A servo press then drives the parts up and down, linking a center correction module and a press head to precisely press pins, tubes, plugs, etc., onto the product. This significantly improves efficiency, increases the new product qualification rate, ensures stable operation, and provides a reliable guarantee for mass production. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown, the controller cover positioning pin press-fit fixture includes a fixture base plate 1, and also includes a vertical plate 2 and a rib plate 3 set above the fixture base plate 1. A positioning plate 4 is bolted to one side of both the vertical plate 2 and the rib plate 3. A lever cylinder 5 is set on the outer side of the positioning plate 4. A pressure head 6 is fixed to the top of the positioning plate 4. A support column 7 is bolted to the top of the fixture base plate 1. The support column 7 is fixed to the bottom of the vertical plate 2 and the rib plate 3. Several positioning pin seats 8 are fixed in a circular array on the outer side of the positioning plate 4. Each of the positioning pin seats 8 can be fitted with a suitable bolt. An electric cylinder 9 is fixed to the top of the fixture base plate 1. The piston rod of the electric cylinder 9 is detachably installed on one side of the support column 7.

[0020] Two positioning discs 4 can be installed by installing a vertical plate 2 and a rib plate 3 above the base plate 1 of the fixture. The vertical plate 2 and the rib plate 3 have the same appearance and are made of the same material. The positioning discs 4 are circular, and the inner diameters of the two positioning discs 4 are also the same.

[0021] The positioning disk 4 can be driven to move by a lever cylinder 5. The lever cylinder 5 is a pneumatic actuator that amplifies output force or changes the direction of motion through a lever mechanism. Its core feature is combining the linear motion of a cylinder with the torque amplification characteristics of a lever. Through the lever arm design, the thrust of the cylinder piston is converted into a larger output force or a longer stroke, achieving a combination of linear and rotary motion, suitable for complex mechanical actions. Compared to the traditional combination of a cylinder and an external lever, the structure is more compact and saves installation space. The fixture body is made of 45# material, heat-treated and chrome-plated, possessing high strength, corrosion resistance, and good stability.

[0022] By setting the pressure head 6, the servo press can achieve up-and-down movement trajectory, and the linkage center correction module can accurately press pins, tubes, plugs, etc. into the product, greatly improving efficiency and increasing the qualification rate of new products. The system is stable, ensuring reliable mass production.

[0023] The support column 7 can support the upright plate 2 and the rib plate 3, and the upright plate 2 and the rib plate 3 can be installed on the fixture base plate 1, which also facilitates the disassembly of the support column 7, the upright plate 2 and the rib plate 3.

[0024] By setting the positioning pin seat 8, it can be installed with the part to be clamped. The part is installed by the matching bolt, so that the part is positioned more accurately before clamping and the assembly is more stable.

[0025] By incorporating an electric cylinder 9, the entire fixture base plate 1 can be moved on the worktable via electric drive, causing the two positioning discs 4 on the fixture base plate 1 to move, thereby moving the parts. This makes the clamping of parts more flexible and improves work efficiency. The electric cylinder 9 is an electromechanical integrated device that converts the rotary motion of an electric motor into precise linear motion. It consists of core components such as a servo motor, a guide rail system, and a lead screw / nut pair. It achieves micron-level repeatability positioning accuracy through closed-loop control (such as encoder feedback). The servo motor can start and stop quickly, adapting to dynamic load changes. It consumes no compressed air, has lower operating costs than pneumatic cylinders, supports customized expansion, and is adaptable to complex mechanical structures.

[0026] Working principle: The operator installs two support columns 7 on the top of the fixture base plate 1 using bolts. The two support columns 7 are respectively fixed with upright plates 2 and rib plates 3. Positioning plates 4 are installed on upright plates 2 and rib plates 3 respectively. The parts to be processed are installed with the positioning pin seats 8 on the positioning plates 4 using the matching bolts to position the parts. Finally, the servo press realizes the up and down movement trajectory, and the linkage center correction module and press head 6 perform precise pressing of the parts, such as pins, tubes, and plugs, which greatly improves efficiency, increases the qualification rate of new products, and ensures stable operation and reliable mass production.
