Description

Technical Field

[0001] This invention relates to the field of high-precision motor assembly, specifically to a high-precision motor positioning pin assembly device. Background Technology

[0002] Currently, the assembly of locating pins is mainly done manually. The operator first picks up the locating pin, visually aligns the locating pin hole, and then uses a tool to apply axial force to the exposed end of the locating pin so that the locating pin is inserted into the locating hole and assembled in place.

[0003] Manual installation by the operator is inefficient. The workpieces are small and difficult to separate and handle. The operator's eyes are strained and easily fatigued, which can easily lead to improper installation. In addition, the end of the locating pin is easily deformed by the force during the installation process, which affects the assembly of the mating parts. The locating pin itself is easily deformed by lateral force, which can lead to the scrapping of the locating pin.

[0004] Chinese Patent CN208628809U discloses a novel positioning pin assembly mechanism, comprising: an automatic positioning pin assembly mechanism, a vibratory feeder, a conveyor line, a tray, a waste bin, a frame, an electrical control box, an industrial computer, a display, and a human-machine interface (HMI). The automatic positioning pin assembly mechanism and the vibratory feeder are connected to the top of the frame. The automatic positioning pin assembly mechanism is located below the vibratory feeder. The tray is located on the conveyor line. The waste bin is connected to one side of the conveyor line. The frame is connected to the conveyor line. The electrical control box is connected to the bottom of the conveyor line. The industrial computer is connected to the lower end of the conveyor line. The display is connected to the upper end of the frame. The HMI is located on one side of the upper end of the frame and connected to the display. Compared with traditional technologies, this invention, by adding an automatic positioning pin assembly mechanism, allows the positioning pin to be automatically inserted into the required hole simply by placing the part to be installed in a certain position and sensing the presence of the part, thus improving work efficiency and saving time.

[0005] For example, Chinese Patent CN103978145B discloses a motor rivet pre-assembly device, including a positioning seat for circumferential positioning of the motor, a positioning pin on the positioning seat, and a transition fit between the positioning pin and the rivet hole on the motor. The device also includes a rivet transfer mechanism that transfers the rivet to the positioning pin and aligns the rivet with the top of the positioning pin. The positioning seat further includes an ejection mechanism for pushing the motor to disengage the rivet hole from the positioning pin. By using the transfer device to align the rivet with the positioning pin, and then the ejection device pushing the rivet hole from the positioning pin onto the rivet, automatic rivet pre-assembly is achieved. This pre-assembly method offers high positioning accuracy and good pre-assembly effect, saving manpower and ensuring production efficiency.

[0006] For example, Chinese Patent CN216633288U discloses a positioning pin pressing device for pressing positioning pins onto a set of force beams. The device includes a worktable, a movable platform mounted on the worktable, a pressing device, and an automatic feeding device. The movable platform is used to place the set of force beams and can move along a set direction on the worktable to move the set of force beams to the pressing position. The automatic feeding device includes a conveying mechanism and a vibrating plate containing a plurality of positioning pins. The vibrating plate blows the positioning pins to the conveying mechanism, which then conveys the positioning pins to the pressing device. The pressing device includes a first driving mechanism and a pressing head. The first driving mechanism drives the pressing head to press down and press the positioning pins into the pin holes of the set of force beams. This utility model provides a positioning pin pressing device with a high degree of automation, significantly improving the pressing efficiency and accuracy of positioning pins.

[0007] In summary, the existing methods for installing positioning pins on high-precision motors have many drawbacks, which are summarized as follows:

[0008] ① The positioning pins of high-precision motors are mainly installed manually by the operator: this is inefficient, the workpieces are small and difficult to separate and handle, the operator's eyes are under great strain and easily fatigued, and the installation is prone to failure. In addition, the end of the positioning pin is easily deformed by the force during the installation process, which affects the assembly of the mating parts. The positioning pin itself is easily deformed by lateral force, which leads to the failure of the positioning pin.

[0009] ② Automated equipment requires large investment and has a long manufacturing cycle. It is suitable for mass production and assembly of a single type of product. However, when dealing with the assembly of various types of motor positioning pins, a large number of equipment and devices need to be replaced.

[0010] ③ The manual placement and removal of positioning pins is unreliable. Operators have a high workload and are prone to visual fatigue after working for a long time. If the machine is placed automatically without supervision, it may continue to work after an accident, causing damage to the equipment.

[0011] ④ Because high-precision motors require locating pins in two positions for installation, existing equipment cannot be designed with an adaptable installation structure for high-precision motors;

[0012] ⑤ How to apply force evenly, moderately, and smoothly when installing the locating pin, ensuring vertical force application so that the locating pin does not deform. Summary of the Invention

[0013] To address the shortcomings of existing technologies, this invention provides a high-precision motor positioning pin assembly device to solve the aforementioned problems.

[0014] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0015] A high-precision motor positioning pin assembly device includes a base, a positioning pin rotation chamber, a pressing device, a pin picking and placing mechanism, a clamping and positioning device, a positioning pin mounting limit device, and a high-precision motor. The positioning pin rotation chamber is rotatably mounted on the base. The pressing device is located above the clamping and positioning device. The pin picking and placing mechanism is correspondingly located below the positioning pin rotation chamber. The clamping and positioning device is mounted on the base and connected to the high-precision motor. The positioning pin mounting limit device is located above the positioning pin rotation chamber, and one end is fixed to the pressing device.

[0016] The positioning pin shifting chamber includes a shifting chamber body, a shifting chamber stop groove, a positioning pin shifting placement groove, a shifting transparent plate, a shifting column, a shifting disk, and a vertical drop block. The shifting chamber stop groove is fixed to the shifting chamber body. The positioning pin shifting placement grooves are arranged in a circular array around the shifting chamber body. The shifting transparent plate is sequentially fixed around the shifting chamber body and corresponds to the position of the positioning pin shifting placement groove. The shifting column is sleeved inside the shifting chamber body. The shifting disk is fixed to the shifting column. The vertical drop block is fixed below the shifting disk.

[0017] The pressing device includes a pressing bracket, a pressing handle, and a push rod mechanism. The pressing handle is movably connected to the push rod mechanism and fixed on the pressing bracket.

The mounting limit stop block is set below the mounting limit seat and docks with the rotation chamber stop slot. The positioning pin of the high-precision motor is installed in a semi-automatic manner, which improves work efficiency and avoids problems such as the difficulty in separating and handling small workpieces, high eye strain for operators, and easy eye fatigue. It is less likely to cause improper installation. During the installation process, the force on the end of the positioning pin and its falling trajectory are kept in line with the high-precision motor. The vertical position is less prone to deformation and less susceptible to lateral force deformation that could cause the positioning pin to fail. Manual placement and removal of the positioning pin is unreliable, and operators face high workloads and are prone to visual fatigue after prolonged work. If the machine is installed automatically without supervision, accidents may occur and the machine may continue to operate, causing damage. Therefore, a balance must be struck between the two: a semi-automatic method is used to install the positioning pin of the high-precision motor. Manual installation experience can prevent the fully automatic machine from continuing to operate mechanically in case of special circumstances, which could damage the equipment and affect subsequent working angles. The semi-automatic device also reduces the workload of many workers.

[0031] ① The positioning pins of the high-precision motor are installed in a semi-automatic manner: This improves work efficiency and avoids problems such as the difficulty in separating and handling small workpieces, the high intensity of eye strain for operators, and eye fatigue. It also makes it less likely to cause improper installation.

With the help of installation experience, operators can avoid the situation that occurs when the machine is installed automatically and continues to operate mechanically, which could damage the equipment and affect subsequent working angles. The semi-automatic device can also reduce the workload of many workers.

[0034] ④ High-precision motors require locating pins in two positions for installation. The clamping and positioning device is designed with an adaptive installation structure to meet the special requirements of high-precision motors.

The shifting column 25 is sleeved inside the shifting chamber body 21. The shifting disk 26 is fixed to the shifting column 25. The vertical drop block 27 is fixed below the shifting disk 26. The shifting transparent plate 24 is made of plexiglass. Through the plexiglass cover, the usage status of the positioning pins in the positioning pin shifting placement groove 23 can be easily identified, facilitating timely replenishment by staff.

[0058] The main body 21 of the indexing chamber is provided with an indexing rotation groove 211, and a bearing is provided in the indexing rotation groove 211. The indexing rotation groove 211 is sleeved on the outside of the indexing column 25. The indexing disk 26 is provided with an indexing pin picking groove 261 and a pin picking stop 262. The pin picking stop 262 is fixed in the indexing pin picking groove 261. The vertical falling block 27 is provided with a vertically stabilizing inner magnet 271.

The push rod side block 334 is fixed to the side of the push rod receiving block 335, and its range of motion is limited within the bracket limiting groove 311. The push rod receiving block 335 is connected to the push rod slide rail 332 and is also movably connected to the other end of the linkage L block 322. When the entire mechanism is in sync, pressing down on the lowering grip 32 causes the push rod slider 333 to move vertically along the push rod slide rail 332 and apply vertical force. Utilizing the lever principle, the push rod head 331 continuously and evenly applies force to the positioning pin mounting location of the high-precision motor 7, achieving uniform, moderate, and stable force application, vertical force application, and no deformation of the positioning pin.

[0062] The pin pick and release mechanism 4 includes a pin pick and release clamping body 41 and a pin pick and release bracket 42. The pin pick and release clamping body 41 is movably connected to the pin pick and release bracket 42 and its position is associated with the positioning pin shifting chamber 2. The pin pick and release bracket 42 is fixed on the base 1. The pin pick and release clamping body 41 includes a clamping body handle 411, a pin pick and release connecting seat 412, a pin pick and release claw 413, and a pin pick and release damping post 414. The clamping body handle 411 is fixed to the side of the pin pick and release connecting seat 412. The pin pick and release claw 413 is located at the front end of the pin pick and release mechanism.

The pin pick / place slider 423 is slidably connected to the pin pick / place slide rail 424.

[0064] The pin-picking gripper 413 includes a pin-picking placement groove 4131, a pin-picking hook 4132, and a hook spring 4133. The pin-picking placement groove 4131 corresponds to the pin-picking hook 4132. The hook spring 4133 is connected to the pin-picking hook 4132. The pin-picking hook 4132 includes a hook head 41321, a hook lever 41322, and a hook rotating column 41323. The bent shape of the hook head 41321 is adapted to the pin-picking placement groove 4131. The shape of the hook lever 41322 is adapted to the internal shape of the pin-picking slot 261. The hook rotating column 41323 is rotatably connected to the inside of the pin-picking gripper 413. When the handle 411 of the pin-picking gripper body 41 moves towards the working position of the high-precision motor 7, the upper surface of the pin-picking gripper body 41 blocks the pin-picking placement groove 23 to prevent the pin-picking from falling out.

[0065] The positioning pins are arranged in an orderly manner by gravity in the positioning pin rotation placement slot 23. When the pin picking mechanism 4 retracts to the pin picking stop 262 inside the pin picking slot 261, the hook head 41322 is blocked by the pin picking stop 262, causing the hook head 41322 to rotate clockwise around the center of the hook rotating column 41323. At this time, the pin picking hook 4132 is in a relaxed state. The positioning pins in the positioning pin rotation placement slot 23 fall in sequence under the action of gravity. The vertical falling block 27 is provided with a vertically stable inner magnet 271 directly below the pin picking hook 4132 to ensure that the positioning pin remains vertical when it falls. The pin picking mechanism 4 moves to the right, and the pin picking hook 4132 leaves the pin picking stop 262. Under the action of the added limit spring 623, the positioning pin is clamped, which ensures that the picking and placing of the positioning pin is stable and reliable, improves work efficiency, reduces the workload of the staff, and avoids visual fatigue.

[0066] The clamping and positioning device 5 includes a clamping and positioning main body 51 and a clamping and positioning moving block 52.

[0067] The clamping and positioning moving block 52 includes a clamping guide rail 521 and a clamping assembly limiting component 522. The clamping guide rail 521 is fixed on the base 1, and the clamping slider 514 can slide on the clamping guide rail 521. The clamping assembly limiting component 522 is arranged opposite to the clamping guide rail 521 and is located at both ends of the clamping and positioning body 51. The pressing device 3 works in conjunction with the clamping and positioning device 5. The pressing device 3 presses down once, and the clamping and positioning device 5 rotates once. One clamping plus one rotation realizes the installation of two positioning pins. The high-precision motor 7 rotates 90° to a high-precision positioning station.

[0068] The positioning pin mounting limiting device 6 includes a mounting limiting seat 61, a mounting limiting stop block 62, and a mounting opening 63. The mounting limiting seat 61 is fixed on the pressing device 3. The mounting opening 63 is opened on the mounting limiting seat 61, and the opening position corresponds to the position of the positioning pin rotation placement groove 23. The mounting limiting stop block 62 is located below the mounting limiting seat 61 and is connected to the rotation chamber stop groove 22. The mounting limiting stop block 62 includes a mounting limiting guide rail 621 and a mounting limiting block 63. 22. A limiting spring 623, a limiting baffle 624, and a limiting lever 625 are added. The limiting guide rail 621 is fixed on the limiting seat 61. The limiting block 622 is slidably disposed on the limiting guide rail 621.

The limiting lever 625 is disposed on the side of the limiting block 622.

[0069] Work mode:

[0070] First, the staff adds positioning pins into each positioning pin rotation placement slot 23 through the addition port 63, places the high-precision motor 7 in the motor placement slot 515, grasps the clamping handle 513 and presses it against any clamping limit piece 517, and then uses the clamping translation handle 516 to move the clamping positioning device 5 to the side of the clamping assembly limit piece 522 at the top rod head 331 of the high-precision motor 7. The above is the preparatory work.

[0071] After preparation, the positioning pins are arranged in an orderly manner by gravity in the positioning pin rotation placement slot 23. When the pin pick-and-place mechanism 4 retracts to the pin pick stop 262 inside the rotation pin pick-and-place slot 261, the hook head 41322 is blocked by the pin pick stop 262, causing the hook head 41322 to rotate clockwise around the center of the hook rotating column 41323. At this time, the pin pick-and-place hook 4132 is in a relaxed state. The positioning pins in the positioning pin rotation placement slot 23 fall in sequence under the action of gravity. The vertical falling block 27 is provided with a vertically stable inner magnet 271 directly below the pin pick-and-place hook 4132 to ensure that the positioning pins remain vertical when falling. The pin pick-and-place mechanism 4 moves to the right, and the pin pick-and-place hook 4132 leaves the pin pick stop 262. Under the action of the added limit spring 623, the positioning pin is clamped. After clamping, the pin pick is then released. Continue gripping the main body handle 411 to move the pin pick and release mechanism 4 to the high-precision motor 7. Press down the grip rod 32 to press the positioning pin into the pin groove of the high-precision motor 7.
