Description

Technical Field

[0001] This utility model relates to the field of positioning pin technology, specifically a multi-station synchronous assembly fixture for motor positioning pins. Background Technology

[0002] Locating pins primarily function as positioning pins in mechanical assembly, determining the relative positions of parts. To effectively prevent relative misalignment between connected parts, two locating pins are typically used, and the distance between them affects positioning accuracy. Interference fit and clearance fit are common fit methods between locating pins and pin holes on the positioned parts; the specific choice depends on the part's structure and performance.

[0003] A search revealed Chinese utility model patent CN218136190U, a fixture for assembling motor positioning pins. The fixture includes a base with a positioning pin receiving groove. A baffle is fixed to one end of the base, and a telescopic cylinder is fixed to the baffle. The output shaft of the telescopic cylinder passes through the baffle and extends into the positioning pin receiving groove. A push plate is fixed to the end of the output shaft. An automatic positioning pin filling device is provided on one side of the top of the base. This automatic positioning pin filling device has the functions of storing positioning pins and filling them into the positioning pin receiving groove on the base. Magnets are used to capture the positioning pins being filled into the groove and to fix the filled pins. The telescopic cylinder pushes the push plate, causing it to act on the positioning pins, thus pressing the positioning pins into the motor positioning holes. This structure assists workers in assembling motor positioning pins, effectively reducing labor intensity and increasing product output.

[0004] The existing device has the following problems when in use: when the positioning pin enters the positioning hole of the motor, the impact force will cause the motor to tilt, making it difficult for the positioning pin to enter at the subsequent angle, resulting in the failure of the assembly of the positioning pin and the motor, and the low assembly efficiency of the positioning pin and the motor. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-station synchronous assembly fixture for motor positioning pins to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station synchronous assembly fixture for motor positioning pins, comprising a base, a control chamber, and a limiting component. The control chamber is located on the top of the base, and a rotary motor is installed inside the control chamber. A lead screw is fastened to the output end of the rotary motor, and a slide is threaded onto the surface of the lead screw. A limiting component is installed on one side of the slide. A conveyor belt is installed on one side of the control chamber, and a connecting seat is installed on one side of the conveyor belt. A positioning pin chamber is located on the top of the connecting seat, and a connecting frame is installed on one side of the connecting seat. A telescopic cylinder is installed on one side of the connecting frame, and a connecting plate is fastened to the output end of the telescopic cylinder. A push rod is installed on one side of the connecting plate.

[0007] By adopting the above technical solution, the positioning hole face of the motor is placed on the conveyor belt facing the connecting seat. The conveyor belt drives the motor to transport the motor. The start of the motor drives the lead screw to rotate. The lead screw, in conjunction with the slide block, drives the limiting component to descend. The motor is located inside the limiting component and the limiting plate. The limiting plate, in conjunction with the limiting component, clamps the motor. The limiting component, in conjunction with the limiting plate, releases the restriction on the motor, allowing the limiting component to rise. This allows the processed motor to be transported, improving processing efficiency. The telescopic cylinder is activated to move the connecting plate. The push rod on one side of the connecting plate enters the through hole, and the positioning pin inside the through hole moves accordingly, thus entering the positioning hole on the motor. The push rod leaves the through hole, and the positioning pin in the channel falls down, facilitating subsequent use.

[0008] Preferably, the limiting member is provided with an electric slide rail inside, and a limiting plate is slidably connected inside the electric slide rail.

[0009] By adopting the above technical solution, the limit plate can be moved by starting the electric slide rail, thereby limiting the motor on the conveyor belt.

[0010] Preferably, the bottom of the positioning pin chamber is provided with a channel that extends into the interior of the connecting seat, and both the channel and the connecting seat are provided with through holes.

[0011] By adopting the above technical solution, the channel setting only allows one positioning pin to pass through, so that the positioning pins are stacked in the channel and fall down in sequence.

[0012] Preferably, a guide rod is slidably connected inside the connecting frame, and one end of the guide rod is connected to a connecting plate.

[0013] By adopting the above technical solution and by setting the guide rod, the connecting plate can maintain linear motion when moving.

[0014] Preferably, two sets of push rods are provided on one side of the connecting plate, and the push rods are adapted to the through holes.

[0015] By adopting the above technical solution, the push rod can directly enter the interior of the through hole when it moves.

[0016] Preferably, the limiting member is L-shaped, and a plurality of positioning pins are placed in the positioning pin compartment.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The rotating motor drives the lead screw to rotate, and the lead screw, together with the slide block, drives the limiting component to descend. The motor is located inside the limiting component and the limiting plate. The electric slide rail is started to drive the limiting plate to move. The limiting plate, together with the limiting component, clamps and fixes the motor, providing stability for the subsequent assembly of the positioning pin and improving the processing quality.

[0019] 2. Start the telescopic cylinder to move the connecting plate. The push rod on one side of the connecting plate enters the through hole, and the positioning pin inside the through hole moves accordingly, thus entering the positioning hole on the motor. The two sets of push rods, together with the two sets of limiting parts and the conveyor belt, improve the assembly efficiency of the positioning pin. Attached Figure Description
