Description

Technical Field

[0001] The present invention belongs to the technical field of pin press-fitting processes, and particularly relates to a pin press-fitting method and a press-fitting device for new energy vehicle workpieces. Background Art

[0002] During the manufacturing process of new energy vehicle workpieces, pin press-fitting is one of the key steps to ensure tight connection between components. Traditional pin press-fitting methods usually rely on mechanical positioning and manual inspection for operation. Although this method can meet production requirements to a certain extent, it has obvious limitations in terms of accuracy and efficiency.

[0003] Specifically, during the pin press-fitting process, a common problem is that the pin may be in an inclined state. This inclination may be caused by position deviation during the feeding process. When the pin is in a non-vertical state when being pressed into the workpiece, that is, it is inclined, it will cause the pin to fail to enter the predetermined position correctly, resulting in ineffective press-fitting between the pin and the workpiece. This not only affects the quality of the final product but may also lead to assembly failure, increase rework costs, and may have an adverse impact on subsequent processes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pin press-fitting method and a press-fitting device for new energy vehicle workpieces in view of the current situation of the prior art.

[0069] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments

[0070] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement conditions, etc. between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly

[0071] As Figures 1 to 11As shown in the figure, a pin press-fitting device for new energy vehicle workpieces according to the present invention includes: a pin positioning member 200, a vision sensor 300, a workpiece positioning table 400, a jaw mechanism 500, a pressing mechanism 600, a press-fitting mechanism 700, and a blowing mechanism 800.

[0072] Specifically, the pin positioning member 200 is used to position the pins to be assembled. In this solution, the pins installed horizontally on the workpiece 900 are defined as horizontal pins, and the pins installed vertically are defined as vertical pins. The pin positioning member 200 is respectively provided with a horizontal pin positioning groove 211 for receiving and positioning the horizontal pins and a vertical pin positioning hole 221 for positioning the vertical pins. Before pressing the pins into the workpiece 900, the pins are respectively placed in the horizontal pin positioning groove 211 and the vertical pin positioning hole 221. Preferably, referring to Figure 6 , the pin positioning member 200 of this solution includes a first positioning table 210 and a second positioning table 220 which are separately arranged. The horizontal pin positioning groove 211 is arranged on the top of the first positioning table 210, and the vertical pin positioning hole 221 is arranged on the top of the second positioning table 220. Of course, the pin positioning member 200 can also be integrally formed.

[0073] The workpiece positioning table 400 is movably arranged on one side of the pin positioning member 200 and is used to carry and move the workpiece 900. Preferably, this solution further includes a workbench 100, and power mechanisms such as linear guides, oil cylinders, and motors are arranged on the workbench 100 to drive the workpiece positioning table 400 to move on the workbench 100, so as to realize the transfer function of the workpiece positioning table 400 for the workpiece 900. Moreover, positioning members are arranged on the workpiece positioning table 400 to position the workpiece 900 placed thereon.

[0074] The jaw mechanism 500 is arranged on one side of the pin positioning member 200 and has a pin jaw 510 movably arranged on one side of the pin positioning member 200, and the pin jaw 510 is defined as a clamping tool for the horizontal pins. The jaw mechanism 500 drives the pin jaw 510 to move left and right and up and down in Figure 2 to clamp the horizontal pins to be assembled into the horizontal pin positioning groove 211. Preferably, the pin jaw 510 is composed of a double-headed cylinder and two clamping blocks arranged at the output end of the double-headed cylinder. The double-headed cylinder drives the two clamping blocks to approach or separate to realize the clamping or release of the horizontal pins.

[0075] The pressing mechanism 600 is arranged above the pin positioning member 200, and its function is to press the workpiece 900 tightly on the workpiece positioning table 400 after the workpiece positioning table 400 transports the workpiece 900 to a predetermined position (the press-fitting position of the pins), so as to prevent the workpiece 900 from shaking when the vertical pins are pressed into the workpiece 900.

[0076] The blowing mechanism 800 is arranged above the pin positioning member 200 and has a guiding tube 810 movably arranged on the pressing mechanism 600. The guiding tube 810 is used to guide the descending path of the vertical pin. Among them, the guiding tube 810 is coaxially arranged with the vertical pin positioning hole 221. The blowing mechanism 800 is used to blow the vertical pin to be assembled through the guiding tube 810 and then into the vertical pin positioning hole 221.

[0077] First, the pin passes through the guiding tube 810 coaxially arranged with the vertical pin positioning hole 221, and then the vertical pin is introduced into the vertical pin positioning hole 221. In this setting method, during the process of the pin moving from the guiding tube 810 to the vertical pin positioning hole 221, the self-gravity of the pin and the initial velocity when entering the guiding tube 810 from the blowing mechanism 800 are fully utilized, reducing the influence of the frictional force between the hole wall of the vertical pin positioning hole 221 and the outer wall of the vertical pin, and ensuring that the pin will not tilt when it is introduced into the vertical pin positioning hole 221.

[0078] Specifically, when the vertical pin is moved into the vertical pin positioning hole 221 by manual operation or mechanical structure of the operator and then released, since the initial velocity of the vertical pin is basically zero, during the process of the vertical pin entering the vertical pin positioning hole 221, the frictional force between the vertical pin and the hole wall of the positioning hole may cause the pin to tilt after moving into place. In this solution, however, the vertical pin is allowed to move in the guiding tube 810 for a period of time to make it have a certain initial velocity before entering the vertical pin positioning hole 221, effectively reducing the tilting problem of the vertical pin caused by frictional force during the moving process.

[0079] The vision sensor 300 is arranged on the pin positioning member 200 and is used to detect the verticality of the vertical pin, further ensuring that the pins are in a vertical state before press-fitting, so as to ensure the press-fitting quality between the pin and the workpiece 900.

[0080] It is worth mentioning that the blowing mechanism 800 of this solution includes: a first driving member 820, which is erected on the pressing mechanism 600; a connecting block 830, which is connected to the output end of the first driving member 820, and the guiding tube 810 is arranged on the connecting block 830; a receiving member 840, which has a first cavity for receiving the vertical pin inside. The receiving member 840 is provided with a discharge hole 841 and an air intake hole 842 both communicating with the first cavity. The discharge hole 841 is communicated with the guiding tube 810 through a pipeline for the vertical pin in the first cavity to move into the guiding tube 810, and the air intake hole 842 is used for the receiving member 840 to communicate with the air source to provide a power source for the blowing mechanism 800 to transport the vertical pin.

[0081] The first driving member 820 can be a power structure such as a cylinder, an oil cylinder, or a motor. During operation, the first driving member 820 first drives the connecting block 830 to move towards the pin positioning member 200, aligning the guiding tube 810 with the vertical pin positioning hole 221. Then, the air source delivers high-pressure gas into the first cavity through the air intake hole 842, causing the pin in the first cavity to be discharged from the discharge hole 841. After passing through the pipeline and the guiding tube 810, the pin enters the vertical pin positioning hole 221. After the pin is transported in place, the first driving member 820 drives the connecting block 830 to reset, driving the guiding tube 810 to reset, so as not to affect the workpiece positioning table 400 to transport the workpiece 900 to the pin pressing position.

[0082] In this solution, the position adjustment of the guiding tube 810 is realized through the first driving member 820 and the connecting block 830, ensuring that the vertical pin can accurately enter the vertical pin positioning hole 221. This design improves the flexibility and adaptability of the system, and at the same time ensures the accurate transportation of the pin.

[0083] Furthermore, the air blowing mechanism 800 further includes: a first support frame 860; a connecting seat 870, which is arranged on the first support frame 860. The connecting seat 870 is provided with a second cavity, as well as a feed hole 871 and a discharge hole 872 that are both communicated with the second cavity. The discharge hole 872 is communicated with the first cavity; a second driving member 880, which is arranged on the connecting seat 870; a material distributing block 890, which is movably arranged in the second cavity and connected to the output end of the second driving member 880. The material distributing block 890 is provided with a material receiving hole 891. The material distributing block 890 has a material receiving state and a material discharging state; when in the material receiving state, the axis of the material receiving hole 891 is collinear with the axis of the feed hole 871, so that the material receiving hole 891 receives the vertical pin introduced from the feed hole 871; when in the material discharging state, the axis of the material receiving hole 891 is collinear with the axis of the first cavity, so that the vertical pin in the material receiving hole 891 enters the first cavity.

[0084] The second driving member 880 can be a power component such as a cylinder or a motor. The first support frame 860 is used to provide support for the connecting seat 870. The second cavity on the connecting seat 870 allows the material distributing block 890 to move inside it. Preferably, the blowing mechanism 800 in this solution further includes a first vibrating disk 850, which is used to transport the pins to the feeding hole 871. During operation, the receiving hole 891 on the material distributing block 890 is aligned with the feeding hole 871 on the connecting seat 870 to receive the pins. The receiving member 840 is connected to the connecting seat 870, and the discharging hole 872 on the connecting seat 870 is communicated with the first cavity of the receiving member 840. After the first vibrating disk 850 transports the pins to the feeding hole 871, the pins will enter the receiving hole 891 under the action of their own gravity. Subsequently, the second driving member 880 drives the material distributing block 890 to move, so that the receiving hole 891 on the material distributing block 890 is aligned with the discharging hole 872 on the connecting seat 870, and the pins enter the first cavity of the receiving member 840 under the action of their own gravity, completing the preliminary feeding process of the pins. Through the design of the material distributing block 890 and its two states, the automatic process of vertical pins from feeding to discharging is realized, greatly improving the working efficiency and reducing the need for manual intervention.

[0085] Preferably, one end of the vertical pin positioning hole 221 facing the workpiece positioning table 400 is provided with a first arc surface 221a, which is used to reduce the contact area between the pin and the vertical pin positioning hole 221 when the vertical pin enters the vertical pin positioning hole 221 from the guide tube 810, so as to further prevent the vertical pin from tilting after entering the vertical pin positioning hole 221.

[0086] Further, a first guide sleeve 410 is provided on the workpiece positioning table 400. The internal space of the first guide sleeve 410 is movably communicated with the vertical pin positioning hole 221, and is used to guide the vertical pin in the vertical pin positioning hole 221 to be press-fitted into the workpiece 900. One end of the first guide sleeve 410 facing the vertical pin positioning hole 221 is provided with a second arc surface 411, which is used to provide an avoidance space between the vertical pin and the first guide sleeve 410 when the vertical pin is pressed into the first guide sleeve 410.

[0087] When the vertical pin is press-fitted, it moves out of the vertical pin positioning hole 221, passes through the first guide sleeve 410 and then enters the workpiece 900. During the movement of the vertical pin, the second arc surface 411 provides an avoidance space for the vertical pin, making it easier for the pin to enter the workpiece 900, reducing the risk of damage, and enhancing the reliability and durability of the device.

[0088] It is worth mentioning that the press-fitting mechanism 700 of this solution includes: a third driving member 710, which is arranged on one side of the pin positioning member 200, and the axis direction of the output shaft of the third driving member 710 is collinear with the axis of the horizontal pin positioning groove 211, for press-fitting the horizontal pin into the workpiece 900; a fourth driving member 720, which is arranged on one side of the pin positioning member 200, and the axis direction of the output shaft of the fourth driving member 720 is collinear with the axis of the vertical pin positioning hole 221, for press-fitting the vertical pin into the workpiece 900; a pressure sensor 730, and the pressure sensor 730 is arranged on both the third driving member 710 and the fourth driving member 720, and the pressure sensor 730 is used to detect the reaction force during pin press-fitting.

[0089] The third driving member 710 and the fourth driving member 720 are preferably motors, and the pressure sensor 730 is electrically connected to the motors. During the pin press-fitting process, if the pin size is too small, too large or tilted, it will affect the assembly quality between it and the workpiece 900. The pressure sensor 730 can detect pins with too large, too small or tilted outer diameters during the pin press-fitting process. For example, when the pin diameter is too small, the reaction force of the workpiece 900 on the pin during the process of pressing the pin into the workpiece 900 will be less than the set value, and at this time the pressure sensor 730 will receive a feedback signal; when the pin diameter is too large or the pin is tilted, the reaction force detected by the pressure sensor 730 will be greater than the set value. By configuring the third driving member 710, the fourth driving member 720 and the pressure sensor 730, not only the precise press-fitting of the horizontal and vertical pins is realized, but also the reaction force generated during the press-fitting process can be monitored in real time to ensure the press-fitting quality.

[0090] The press-fitting mechanism 700 of this solution further includes: a support seat 740, which is arranged on the workpiece positioning table 400; a fifth driving member 750, which is arranged on the support seat 740; an abutting block 760, which is arranged at the output end of the fifth driving member 750, and one end of the abutting block 760 is movably abutted against the workpiece 900, for providing support for the workpiece 900 when press-fitting the horizontal pin.

[0091] The fifth driving member 750 can be a power component such as a cylinder, a motor or an oil cylinder, and the support seat 740 is used to provide support for the fifth driving member 750. The abutting block 760 is used to provide support for the part of the workpiece 900 where the horizontal pin needs to be press-fitted during the press-fitting of the horizontal pin, to prevent the workpiece 900 from deforming.

[0092] It is worth mentioning that the jaw mechanism 500 includes: a second support frame 520; a sixth driving member 530 horizontally disposed on the second support frame 520; a seventh driving member 540 vertically disposed at the output end of the sixth driving member 530, and the pin jaw 510 is connected to the output end of the seventh driving member 540; a conveying track 550 disposed on one side of the pin positioning member 200 for conveying the horizontal pins to be assembled, and a clamping position 551 is provided on the conveying track 550. When the conveying track 550 conveys the horizontal pins to the clamping position 551, the pin jaw 510 clamps the horizontal pins.

[0093] The second support frame 520 is used to provide support for the jaw mechanism 500. Both the sixth driving member 530 and the seventh driving member 540 are preferably linear guides. Preferably, the jaw mechanism 500 of this solution includes a second vibrating disk 560. The discharging end of the second vibrating disk 560 is connected to the conveying track 550. The horizontal pins are conveyed to the clamping position 551 through the second vibrating disk 560 and the conveying track 550, and then the sixth driving member 530 and the seventh driving member 540 drive the pin jaw 510 to move along Figure 2 the left - right and up - down directions as shown to complete the conveyance of the horizontal pins from the clamping position 551 to the horizontal pin positioning groove 211.

[0094] In this solution, the pressing mechanism 600 includes: at least two columns 610 spaced apart and distributed on the side of the workpiece positioning table 400; a support block 620 disposed at the upper ends of the at least two columns 610; an eighth driving member 630 erected on the support block 620; a moving seat 640 connected to the output end of the eighth driving member 630; a connecting sleeve 650 disposed at the end of the moving seat 640 away from the eighth driving member 630; a pressing block 660 movably inserted into the connecting sleeve 650; an elastic member 670 sleeved on the outer periphery of the pressing block 660. A limiting portion 661 is provided on the pressing block 660. One end of the elastic member 670 abuts against the limiting portion 661, and the other end abuts against the connecting sleeve 650; a guiding column 680. A second guiding sleeve 621 is provided on the support block 620. One end of the guiding column 680 passes through the second guiding sleeve 621 and is connected to the moving seat 640 to provide guidance for the movement of the moving seat 640.

[0095] The eighth driving member 630 can be a power component such as a cylinder or a motor, and the elastic member 670 is preferably a spring. After the workpiece 900 is transported to the pin pressing position through the workpiece positioning table 400, the eighth driving member 630 drives the moving seat 640 to move the pressing block 660 towards the workpiece 900. When the pressing block 660 contacts the workpiece 900, it stops further independent movement, while the eighth driving member 630 continues to push the moving seat 640. At this time, the pressing block 660 begins to compress the elastic member 670 and continuously applies pressure to the workpiece 900. The column 610 and the support block 620 are used to provide stable support for the pressing mechanism 600. In this solution, components such as the column 610 and the support block 620 are used to construct a stable pressing platform, and the elastic member 670 and the guide post 680 are used to ensure the smooth movement of the pressing block 660, providing uniform pressure for the workpiece 900 and preventing the workpiece 900 from shifting or being damaged during the pressing process.

[0096] This solution also proposes a pin pressing method for new energy vehicle workpieces, including the steps of:

[0097] S1. Transport the vertical pin to the vertical pressing position through the blowing mechanism 800, and transport the horizontal pin to the horizontal pressing position through the jaw mechanism 500;

[0098] S2. Detect the verticality of the vertical pin through the vision sensor 300. If the detected inclination angle exceeds the threshold value, trigger the alarm device and pause the process to wait for manual adjustment; if the verticality is qualified, execute step S3;

[0099] S3. Transport the workpiece 900 to the predetermined position through the transport mechanism, and tightly fix the workpiece 900 through the pressing mechanism 600;

[0100] S4. Press the vertical pin and the horizontal pin into the workpiece 900 through the pressing mechanism 700 to complete the pin pressing operation.
