Description

Technical Field

[0001] The invention relates to a press-fit and detection device for a power driver component, in particular to a press-fit detection device for an actuator tail cover assembly. Background Art

[0002] Power drives can be divided into linear actuators, rotary actuators, etc. Linear actuators are actuators that output linear motion, while rotary actuators output rotary motion. Linear actuators (motors) are composed of rotors and stators. The rotor is a rotating component and is a device used to convert electrical energy into mechanical energy and mechanical energy into electrical energy. At present, linear actuators generally include brush holder components (including brush holder body, inductor, carbon brush, carbon brush spring, etc.), tail cover components (including tail cover body, magnet, etc.), stator assembly (including magnetic tile, stator housing), rotor assembly (including rotor and silicon steel sheet, rotor shaft, output shaft, commutator, etc.), among which, the tail cover component includes tail cover body, magnet assembly, spring, power plug, guide spring, etc. The guide spring is pressed into the tail cover body by the magnet assembly, and the magnet assembly is then pressed and positioned by the spring. The power plug is installed in the tail cover body and docked with the socket, and a part is exposed to the outside. After the tail cover assembly undergoes the injection molding manufacturing process, the exposed height of the power plug may be tilted or uneven. It is necessary to detect the elastic force of the magnet assembly to verify whether the spring piece is pressed into place. The guide spring may also be missed, and the pressure of the spring piece also needs to be tested separately. There is a lack of unified and integrated positioning and detection devices, which cannot ensure the overall quality of the tail cover assembly. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies in the prior art and to provide an automatic press-fit detection device for an actuator tail cover assembly, which can press-fit the tail cover assembly into place and realize power plug height detection, spring sheet pressure detection, and magnet assembly elastic force detection.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an automatic press-fit detection device for an actuator tail cover assembly, comprising a turntable base and a turntable, the turntable being connected to a turntable rotation power source, a power plug height detection mechanism, a spring pressure detection mechanism, and a magnet assembly elastic force detection mechanism being sequentially mounted on the turntable base and at the periphery of the turntable, a plurality of magnet assembly positioning mechanisms being mounted on the periphery of the turntable, the magnet assembly positioning mechanism comprising a positioning base mounted on the periphery of the turntable, a tail cover tooling base and a column being mounted on the positioning base and being close to each other, a push block being mounted on the upper part of the column, and the push block being located above the tail cover tooling base.

[0005] The power plug height detection mechanism comprises a height detection fixing seat, on which a lateral moving component is mounted, on which a height detection longitudinal moving component is mounted, and on which a displacement sensor and a displacement rod are mounted.

[0006] The spring sheet pressure detection mechanism comprises a pressure detection fixing seat, on which a pressure detection longitudinal moving assembly is mounted, and the pressure detection longitudinal moving assembly is connected to a pressure sensor and a spring sheet pressing rod.

[0007] The magnet assembly elastic force detection mechanism includes an elastic force detection fixed seat, on which is mounted an elastic force detection longitudinal moving component, the elastic force detection longitudinal moving component is connected to the elastic force sensor and the magnet assembly press-fitting head, and a push block driving power source is mounted on the elastic force detection fixed seat and on the side of the magnet assembly press-fitting head.

[0008] After adopting the structure of the present invention, the tail cover assembly to be inspected is placed on the tail cover tooling base of the magnet assembly positioning mechanism and the magnet assembly is pressed by the push block for positioning. The power plug height detection mechanism performs the power spring height detection, the spring pressure detection mechanism performs the spring pressure detection, and the magnet assembly elastic force detection mechanism performs the magnet assembly elastic force detection in sequence. By automatically and uniformly completing the press-fitting of the tail cover assembly and the related performance detection, the overall quality of the tail cover assembly is effectively guaranteed and the work efficiency is significantly improved.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] Reference Figure 1It can be known that the automatic press-fit detection device of the actuator tail cover assembly of the present invention includes a turntable base 51 and a turntable 52.

[0016] like Figure 1 , Figure 5 As shown, the tail cover assembly 58 installed on the tail cover tooling base 7 of the magnet assembly positioning mechanism 57 includes a tail cover body 11, a magnet assembly 13, a spring 14, a power plug 15, a guide spring 12, etc. The guide spring 12 is pressed into the tail cover body 11 by the magnet assembly 13, and the magnet assembly 13 is press-fitted and positioned by the spring 14. The power plug 15 (two pieces) is installed in the tail cover body 11 and docked with the socket, and a part of it is exposed to the outside.

[0017] like Figure 1 , Figure 2 As shown, the power plug height detection mechanism 54 includes a height detection fixing seat 22, on which a lateral moving assembly 21 is mounted, on which a height detection longitudinal moving assembly 25 is mounted, and on which (through a displacement fixing seat 23) a displacement sensor 24 (in the upper position) and a displacement rod 26 (in the lower position) are mounted. Below the displacement rod 26 is a magnet assembly positioning mechanism 57 that has been rotated into place and a tail cover assembly 58 mounted on the tail cover tooling base 7.

[0018] like Figure 1 , Figure 3 As shown, the spring pressure detection mechanism 55 includes a pressure detection fixed seat 34, on which a pressure detection longitudinal moving assembly 31 is mounted, and the pressure detection longitudinal moving assembly 31 is connected to a pressure sensor 32 (in the upper position) and a spring press rod 33 (in the lower position). Below the spring press rod 33 is a magnet assembly positioning mechanism 57 rotated into place and a tail cover assembly 58 mounted on the tail cover tooling base 7.

[0019] like Figure 1 , Figure 4 As shown, the magnet assembly elastic force detection mechanism 56 includes an elastic force detection fixed seat 44, on which an elastic force detection longitudinal moving assembly 41 is installed, and the elastic force detection longitudinal moving assembly 41 is connected to an elastic force sensor 42 (in the upper position) and a magnet assembly press-fitting head 43 (in the lower position), and a push block driving power source 45 (a push block driving cylinder with a cylinder piston push rod) is installed on the elastic force detection fixed seat 44 and on the side of the magnet assembly press-fitting head 43. Below the magnet assembly press-fitting head 43 is the magnet assembly positioning mechanism 57 rotated into place and the tail cover assembly 58 installed on the tail cover tooling base 7.

[0020] The working process of the present invention is as follows: 1. Description of the work flow of installation or disassembly station A: First, pre-assemble the guide column spring 12, the magnet assembly 13, the spring 14, the power plug 15, etc. to form the tail cover assembly 58 to be tested, and the magnet assembly 13, the spring 14, and the power plug 15 are facing upward, and then push the push block 6 of the magnet assembly positioning mechanism 57 to pre-install, press, and position the magnet assembly 13, and place it on the tail cover tooling base 7, press the start button, the turntable rotates, and turns to the next "power plug height detection B" station; at the same time, this A station is also a disassembly flow station after completing the relevant inspections.

[0021] 2. Description of the workflow of the power plug height detection station B: After rotating through the A station, the lateral moving component 21 with the height detection longitudinal moving component 25 moves to the top of the power plug 15, and then the height detection longitudinal moving component 25 with the displacement fixing seat 23, the displacement sensor 24 and the displacement rod 26 moves downward to perform a height detection on a power spring, and the detection displacement range is 12.6-12.9mm. After the detection is completed, the height detection longitudinal moving component 25 with the displacement fixing seat 23, the displacement sensor 24 and the displacement rod 26 moves upward and rises and returns to the starting point, and the lateral moving component 21 drives the height detection longitudinal moving component 25 to move to the top of another power spring, and then the height detection longitudinal moving component with the sensor fixing seat 23, the displacement sensor 24 and the displacement rod 26 moves downward to perform a height detection on another power spring, and the detection displacement range is 12.6-12.9mm; if it exceeds the displacement range, an alarm will be issued. After the test is completed, the horizontal moving components are returned to the initial position, and the start button is pressed. The turntable rotates and turns to the next "shrapnel pressure test C" station. The purpose of this station is to mainly detect the height of the power plug through the displacement sensor to prevent the power plug from tilting and uneven height after the tail cover assembly is injected.

[0022] 3. Description of the workflow of the shrapnel pressure detection station C: After rotating through the B station, the pressure detection longitudinal moving component 31 with the pressure sensor 32 and the shrapnel pressing rod 33 moves downward to the shrapnel 14, and the pressure sensor 32 detects the pressure of the shrapnel to detect whether the shrapnel is pressed into place. The pressure range is set at 400-1600N; if it exceeds the pressure range, an alarm will be issued. After the shrapnel is pressed, the pressure detection longitudinal moving component returns to the initial position, the start button is pressed, and the turntable rotates to the next "magnet assembly elastic force detection D" station. The purpose of this station is to press the shrapnel. During the pressing process, the pressure sensor detects the pressure of the shrapnel to ensure that the shrapnel is pressed into place.

[0023] 4. Description of the workflow of the magnet assembly elastic force detection station D: After rotating through the C process, the push block pushes the power source 45 to push the push block 6 to eject the magnet assembly 13, and then the elastic force detection longitudinal moving component 41 works and moves downward to the magnet assembly with the elastic force sensor 42 and the magnet assembly press-fitting head 43, and the elastic force of the magnet assembly is detected by the elastic force sensor 42. The elastic force (press-fitting force) range is set at 4-12N; if it exceeds the elastic force range, an alarm will be issued to verify whether the spring piece is pressed in place. After the test is completed, the elastic force detection longitudinal moving component and the like return to the initial position, press the start button, the turntable rotates, and turns to the next "installation or removal A" station to complete the removal of the tail cover assembly to be tested and the installation of the tail cover assembly to be tested. The purpose of this station is to mainly detect the elastic force of the magnet assembly through the elastic force sensor to verify whether the spring piece is pressed in place, and at the same time prevent the guide spring 12 from being missed (if the guide spring is missed, the elastic force of the magnet assembly is 0).
