Description

An arm-penetrating device Technical Field

[0001] This invention belongs to the field of limiter processing, and more specifically, relates to an arm-piercing device. Background Technology

[0002] A door limiter is a device that restricts the degree to which a car door can open and can keep the door open when needed. A door limiter consists of a limit arm, a limit box, and a limiter bracket. The limiter bracket is fastened to the vehicle body with a mounting bolt, and the limit box is fastened to the door with two mounting screws. When the door is opened or closed, the limit box moves along the limit arm. The limit arm has segments of different heights and grooves, forming multiple different limiting points that can restrict the door to different opening angles.

[0003] During the manufacturing process of the door limiter, the limit arm needs to be inserted into the opening of the limit box using an arm-inserting device. Due to the structural characteristics of different heights of the various arm segments on the limit arm, the limit arm and the limit box are prone to shaking and displacement when the existing arm-inserting device is used for the arm-inserting operation. This results in dents and scratches on the limit arm and the limit box, leading to unsatisfactory arm-inserting effect, reduced processing efficiency, and low yield. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the process of inserting the arm into the door limiter, the limiting arm and the limiting box are prone to shaking and displacement, which causes dents and scratches on the limiting arm and the limiting box, resulting in unsatisfactory insertion effect and low yield.

[0005] To achieve the above objectives, the present invention provides an arm-penetrating device, wherein the door limiter includes a limiting arm and a limiting box, the limiting arm has a vehicle body connecting end and a door connecting end, and the limiting box has an opening slot in the middle, and the arm-penetrating device is used to push the limiting arm from the vehicle body connecting end through the opening slot until the door connecting end fits against the limiting box;

[0015] Optionally, the second end is provided with a position sensor for detecting whether the limiting arm is placed inside the arm-piercing fixture.

[0016] Optionally, guide members are respectively provided on the inner walls of both sides of the arm-piercing fixture, and an arm-piercing area opposite to the opening slot is reserved between the guide members. The guide members are hinged to the arm-piercing fixture through a fixed shaft and a torsion spring.

A limiting member matching the vehicle body connection end is provided on one side of the first anti-jump block. The front end of the limiting member abuts into the opening groove of the limiting box.

[0018] Optionally, one end of the limiting member passes through the first anti-jump block and is connected to the first anti-jump block by a spring. The other end of the limiting member is provided with a stop at its top. A proximity sensor is provided on one side of the first anti-jump block to detect whether the stop moves toward the first anti-jump block.

[0019] Optionally, the second anti-jump mechanism includes a second drive cylinder, an anti-jump guide rod, a second anti-jump block, and a first support frame and a second support frame respectively disposed on both sides of the movable fixture platform.

The longitudinal position of the second anti-jump block on the anti-jump guide rod is adjustable.

[0020] Optionally, the top of the first support frame is provided with a first slide rail, and the top of the second support frame is provided with a second slide rail. Both the first slide rail and the second slide rail are inclined downwards along the middle of the through-arm fixture towards the limiting box. The two ends of the anti-jump guide rod are respectively provided with sliders that match the first slide rail and the second slide rail.

[0021] The second drive cylinder is tilted on one side of the anti-jump guide rod and is used to drive the anti-jump guide rod to move along the first slide rail and the second slide rail toward the limiting box. The tilt angles of the first slide rail, the second slide rail and the second drive cylinder are the same.

[0022] The beneficial effects of the present invention are as follows: the arm-piercing device of the present invention includes a movable fixture table, a feeding mechanism, a pushing arm mechanism, a first anti-jump mechanism and a second anti-jump mechanism, and the movable fixture is provided with an arm-piercing fixture, a box fixture and a lifting mechanism.

[0023] The feeding mechanism transports the moving fixture to the arm-piercing station. The lifting mechanism drives the arm-piercing fixture to move up and down so that its position corresponds with each mechanism. The first anti-jump mechanism abuts against the limit box and cooperates with the box fixture to laterally limit it. The second anti-jump mechanism presses against the limit box to laterally limit it. The push arm mechanism pushes the limit arm along the arm-piercing fixture to the opening slot of the limit box. When the vehicle body connection end is passed through the limit box, the first anti-jump mechanism continues to laterally limit the limit arm, while the push arm mechanism continues to push the limit arm to the target position.

[0024] The arm-threading device of the present invention, through the cooperation of the first anti-jump mechanism, the box fixture, and the second anti-jump mechanism, simultaneously positions the limiting box laterally and longitudinally, preventing the limiting box from shaking as the position of the limiting arm changes during the arm-threading process, thus preventing bumps and scratches. At the same time, the second anti-jump mechanism applies pressure to the vehicle body connection end, guiding the arm-threading path of the limiting arm and reducing the shaking amplitude of the limiting arm, preventing the limiting arm from deviating and bumping during the arm-threading process. This arm-threading device can effectively reduce the occurrence of bumps, scratches, and displacement of the limiting device, improving product quality and processing efficiency.

[0037] Referring to Figures 1-4, the arm-penetrating device of this embodiment of the invention includes a door limiter 100 comprising a limiting arm 110 and a limiting box 120. The limiting arm 110 has a vehicle body connecting end 111 and a door connecting end 112. The limiting box 120 has an opening groove 121 in the middle. The arm-penetrating device is used to push the limiting arm 110 from the vehicle body connecting end 111 through the opening groove 121 until the door connecting end 112 is in contact with the limiting box 120.

[0038] The arm-mounting device includes a movable fixture table 200, a feeding mechanism 700, a pushing arm mechanism 400, a first anti-jump mechanism 500, and a second anti-jump mechanism 600;

[0039] The mobile fixture table 200 is provided with an arm-through fixture 210 and a box fixture 220 that matches the limiting box 120. The arm-through fixture 210 has a first end 211 and a second end 212. The box fixture 220 is disposed at the first end 211. The limiting box 120 is disposed inside the box fixture 220. The limiting arm 110 is disposed inside the arm-through fixture 210. The vehicle body connecting end 111 is opposite to the opening slot 121 of the limiting box 120, and the door connecting end 112 is opposite to the second end 212.

[0040] The feeding mechanism 700 is located at the bottom of the mobile fixture table 200 and is used to transport the mobile fixture table 200 to the arm-passing station corresponding to the push arm mechanism 400, the first anti-jump mechanism 500 and the second anti-jump mechanism 600.

[0041] The push arm mechanism 400 is located at the second end 212 and is used to push the limiting arm 110 into the opening slot 121 to the target position along the arm-through fixture 210.

[0042] The first anti-jump mechanism 500 is disposed at the first end 211 and is used to cooperate with the box fixture 220 to laterally limit the limiting box 120 and apply pressure to the vehicle body connection end 111 opposite to that of the push arm mechanism 400. The pressure applied by the first anti-jump mechanism 500 to the vehicle body connection end 111 is less than the pressure applied by the push arm mechanism 400 to the door connection end 112.

[0043] The second anti-jump mechanism 600 is used to longitudinally limit the limit box 120.

[0044] Specifically, referring to Figure 2, in this embodiment of the invention, the feeding mechanism 700 includes a transmission belt 710 and a drive motor 720. The upstream station of the arm-feeding device in this embodiment of the invention sets the arm-feeding fixture 210, the limiting arm 110 and the limiting box 120 on the corresponding positions of the moving fixture table 200, and then the conveyor belt 710 transports the moving fixture table 200 to the arm-feeding station.

[0045] Furthermore, Figure 5 shows a structural schematic diagram of the combination of the movable jig plate, the through-arm jig, the housing jig, the limiter and the lifting mechanism according to an embodiment of the present invention. Referring to Figure 5, in this embodiment of the present invention, the movable jig platform 200 is provided with a lifting mechanism 300, which includes a lifting cylinder 310 and a lifting plate 320. The lifting plate 320 is connected to both the output end of the lifting cylinder 310 and the through-arm jig 210.

[0046] Specifically, in this embodiment of the invention, the lifting cylinder 310 drives the lifting plate 320 and the arm-piercing fixture 210 to rise or fall, thereby adjusting the longitudinal height of the arm-piercing fixture 210 so that the positions of the arm-piercing fixture 210, the push arm mechanism 400, the first anti-jump mechanism 500 and the second anti-jump mechanism 600 are matched to complete the arm-piercing operation.

[0047] Furthermore, Figure 6 shows a schematic diagram of the push arm mechanism according to an embodiment of the present invention. Referring to Figure 6, in this embodiment of the present invention, the push arm mechanism 400 includes a push arm electric cylinder 410, a push arm guide rod 420, and a push arm guide block 430. The push arm guide block 430 is connected to the output end of the push arm electric cylinder 410 through the push arm guide rod 420, and the longitudinal position of the push arm guide block 430 on the push arm guide rod 420 is adjustable.

[0048] Specifically, in this embodiment of the invention, the push arm guide block 430 is disposed at the end of the push arm guide rod 420 away from the push arm electric cylinder 410. A third slide rail 421 matching the push arm guide block 430 is provided on the push arm guide rod 420. A first bolt 440 is provided at the top of the push arm guide block 430. One end of the first bolt 440 is connected to the push arm guide rod 420 through a connector. By adjusting the first bolt 440, the push arm guide block 430 can be moved up and down along the third slide rail 421, thereby adjusting the longitudinal position of the push arm guide block.

[0049] Specifically, in this embodiment of the invention, the push arm guide rod 420 includes a first push arm guide rod 422 and a second push arm guide rod 423 that are slidably connected, and a second buffer spring 450 is connected between the first push arm guide rod 422 and the second push arm guide rod 423.

[0050] Specifically, in this embodiment of the invention, an electric cylinder is used as the driving device for the push arm mechanism 400, which can control the distance and speed of the push arm guide block 430 to move, improve the accuracy of processing, and make corresponding adjustments to the push arm cylinder for different models of products, thus achieving higher adaptability.

[0051] Specifically, in this embodiment of the invention, the push arm guide block 430 has a T-shaped structure.

[0052] Furthermore, referring to Figures 4 and 5, in this embodiment of the invention, the arm-piercing fixture 210 has an arm-pushing guide groove 213 that matches the arm-pushing guide block 430. The arm-pushing guide groove 213 is opposite to the opening groove 121, and the movement trajectory of the arm-pushing guide block 430 is limited by the arm-pushing guide groove 213.

[0053] Specifically, in this embodiment of the invention, the push arm guide groove 213 extends from the second end 212 along the arm-penetrating direction to the middle of the arm-penetrating fixture 210. The limiting arm 110 is placed above the push arm guide groove 213. When the push arm guide block 430 moves from the second end 212 to the end of the push arm guide groove 213, the lifting mechanism 300 drives the arm-penetrating fixture 210 to move down a certain distance, so that the bottom end of the push arm guide block 430 exits the push arm guide groove 213 upward and continues to move forward.

[0054] Furthermore, in this embodiment of the invention, a position sensor 800 is provided at the second end 212 of the arm-piercing fixture 210 to detect whether the limiting arm 110 is placed inside the arm-piercing fixture 210.

[0055] Specifically, in this embodiment of the invention, the position sensor 800 is a photoelectric sensor, including a photoelectric transmitter and a photoelectric receiver respectively disposed on both sides of the arm-piercing fixture 210. When the position sensor 800 detects that the limiting arm 110 is located inside the arm-piercing fixture 210, the position sensor 800 transmits a signal to the external automatic control unit, and the arm-piercing device operates normally. Otherwise, the position sensor 800 issues an audible and visual alarm until the position information of the limiting arm 110 is detected.

[0056] Furthermore, in this embodiment of the invention, guide members 214 are respectively provided on the inner walls of both sides of the arm-piercing fixture 210. An arm-piercing area opposite to the opening groove 121 is reserved between the guide members 214. The guide members 214 are hinged to the arm-piercing fixture 210 through a fixed shaft 215 and a torsion spring 216. The torsion spring 216 is sleeved on the fixed shaft 215. The limiting arm 110 overcomes the torsional force of the torsion spring 216 and passes through the arm-piercing area into the opening groove 121.

[0057] Specifically, in this embodiment of the invention, the guide member 214 guides the limiting arm 110 to prevent the limiting arm 110 from deviating during movement.

[0058] Furthermore, in this embodiment of the invention, the first end 211 is also provided with an inclined guide block 218 opposite to the bottom end of the opening groove 121 to guide the limiting arm 110.

[0059] Furthermore, Figure 7 shows a schematic diagram of the structure of the first anti-jump mechanism according to an embodiment of the present invention. Referring to Figure 7, in this embodiment of the present invention, the first anti-jump mechanism 500 includes a first driving cylinder 510, a through-arm guide rod 520, and a first anti-jump block 530. The first anti-jump block 530 is connected to the output end of the first driving cylinder 510 through the through-arm guide rod 520. The longitudinal position of the first anti-jump block 530 on the through-arm guide rod 520 is adjustable. A limiting member 540 matching the first end of the limiting arm 110 is provided on one side of the first anti-jump block 530. The front end of the limiting member 540 abuts into the opening groove 121 of the limiting box 120.

[0060] Specifically, in this embodiment of the invention, the box fixture 220 has a clearance area 221 that matches the limiting member 540.

[0061] Specifically, in this embodiment of the invention, the first anti-jump block 530 and the through-arm guide rod 520 are connected by a fixing plate 550. The fixing plate 550 is provided with a fourth slide rail 551 that matches the first anti-jump block 530. A second bolt 560 is passed through the top of the first anti-jump block 530. The second bolt 560 is connected to the fixing plate 550 through a connector. By adjusting the second bolt 560, the first anti-jump block 530 can move up and down along the fourth slide rail 551, thereby adjusting the longitudinal position of the first anti-jump block 530.

[0062] Furthermore, in this embodiment of the invention, one end of the limiting member 540 passes through the first anti-jump block 530 and is connected to the first anti-jump block 530 through the first buffer spring. A stop 541 is provided at the top of the other end of the limiting member 540, and a proximity sensor 900 is provided on one side of the first anti-jump block 530 to detect whether the stop 541 moves toward the first anti-jump block 530.

[0063] Specifically, in this embodiment of the invention, when the vehicle body connecting end 111 passes through the opening slot 121 of the limiting box 120 and abuts against the limiting member 540, the push arm electric cylinder 410 continues to advance forward, causing the first buffer spring to be compressed, and the limiting member 540 to move closer to the first anti-jump block 530. When the stop block 541 enters the detection range of the proximity sensor 900, the push arm electric cylinder 410 continues to advance forward, causing the limiting arm 110 to pass through to the target position. If the proximity sensor 900 cannot detect the approach of the stop block 541 after the push arm electric cylinder 410 has advanced a certain distance, it indicates that the limiting arm 110 may be misaligned or the machine may be running idle. At this time, the push arm electric cylinder 410 stops running.

[0064] Furthermore, Figure 8 shows a schematic diagram of the structure of the second anti-jump mechanism according to an embodiment of the present invention. Referring to Figure 8, in this embodiment of the present invention, the second anti-jump mechanism 600 includes a second drive cylinder 610, an anti-jump guide rod 620, a second anti-jump pressure block 630, and a first support frame 640 and a second support frame 650 respectively disposed on both sides of the movable fixture platform 200. The two ends of the anti-jump guide rod 620 are respectively disposed on the first support frame 640 and the second support frame 650. The second anti-jump pressure block 630 is connected to the output end of the second drive cylinder 610 through the anti-jump guide rod 620. The longitudinal position of the second anti-jump pressure block 630 on the anti-jump guide rod 620 is adjustable.

[0065] Specifically, in this embodiment of the invention, the second anti-jump block 630 is disposed at the bottom of the anti-jump guide rod 620, and the third bolt 660 passes through the anti-jump guide rod 620 and is disposed at the top of the second anti-jump block 630. The height of the second anti-jump block 630 is adjusted by adjusting the third bolt 660.

[0066] Furthermore, in this embodiment of the invention, a first slide rail 641 is provided at the top of the first support frame 640, and a second slide rail 651 is provided at the top of the second support frame 650. Both the first slide rail 641 and the second slide rail 651 are inclined downward along the middle of the through-arm fixture 210 toward the limiting box 120. The two ends of the anti-jump guide rod 620 are respectively provided with a first slider 621 and a second slider 622 that match the first slide rail 641 and the second slide rail 651.

[0067] The second drive cylinder 610 is inclinedly disposed on one side of the anti-jump guide rod 620 and is used to drive the anti-jump guide rod 620 to move along the first slide rail 641 and the second slide rail 651 toward the limit box 120. The first slide rail 641, the second slide rail 651 and the second drive cylinder 610 have the same inclination angle.

[0068] Specifically, in this embodiment of the invention, the anti-jump guide rod 620 is driven by the second drive cylinder 610 to move downward along the first slide rail 641 and the second slide rail 651 to above the second anti-jump pressure block 630 moving limit box 120, and presses down the limit box 120 to prevent it from shaking.

[0069] In the application of the door limiter 100 of this embodiment, the limiting box 120 is placed in the box fixture 220, the limiting arm 110 is placed in the arm-penetrating fixture 210, and the vehicle body connecting end 111 is opposite to the opening slot 121 of the limiting box 120. The door connecting end 112 is placed at the second end 212. The loading mechanism 700 transports the moving fixture table 200 carrying the arm-penetrating fixture 210, the limiting arm 110 and the limiting box 120 to the corresponding arm-penetrating station. The lifting cylinder 310 is activated, driving the arm-penetrating fixture 210 to move upward, and adjusting the position of the arm-penetrating fixture 210 so that the first end 211 is opposite to the opening slot. Corresponding to 121, the longitudinal positions of the push arm guide block 430, the first anti-jump block 530, and the second anti-jump block 630 are adjusted according to the height of the limit box 120 and the through-arm fixture 210 to make the mechanisms compatible with each other; the first anti-jump mechanism 500 is activated, and the first drive cylinder 510 drives the first guide block to move towards the limit box 120 until the front end of the limit member 540 abuts into the opening groove 121, thus laterally limiting the limit box 120. At the same time, the second anti-jump mechanism 600 is activated, and the second drive cylinder 610 drives the anti-jump guide rod 620 to move downward along the first slide rail 641 and the second slide rail 651 to the second anti-jump block 630. The top of the limiting box 120 is pressed down to limit its longitudinal movement and prevent it from shaking during the arm insertion process. At this time, the push arm mechanism 400 is activated, and the push arm electric cylinder 410 is activated to drive the push arm guide rod to move the push arm guide block 430 towards the arm insertion fixture 210. The bottom end of the push arm guide block 430 extends into the guide groove and pushes the limiting arm 110 towards the opening groove 121 along the guide groove. The vehicle body connecting end 111 passes through the arm insertion area between the guide members 214 and enters the opening groove 121, abutting against the limiting member 540. After the vehicle body connecting end 111 abuts against the limiting member 540, it continues to move through the opening groove 121. The limiting member 540 moves towards the opening groove 121. The first anti-jump block 530 moves in the direction of the buffer spring, the stop block 541 enters the detection range of the proximity sensor 900, and the push arm guide block 430 continues to move forward until the buffer spring is in a fully compressed state. Since the force applied by the first drive cylinder 510 to the limit arm 110 is less than the force applied by the push arm electric cylinder 410 to the limit arm 110, while the push arm electric cylinder 410 continues to drive the push arm guide block 430 forward, the vehicle body connecting end 111 abuts against the limit member 540 and the first anti-jump block 530 to push the through arm guide rod 520 back towards the first anti-jump cylinder until the limit arm 110 passes through the limit box 120 to the target position.

[0070] While one or more embodiments of the present invention have been described above, those skilled in the art will recognize that the present invention can be implemented in any other form without departing from its spirit and scope. Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
