Description

Technical Field

[0001] This utility model relates to the field of clamp platform flipping technology, specifically to a clamp platform flipping detection mechanism. Background Technology

[0002] In the application of clamp transfer systems, the clamp table assembly and clamp seat assembly have two states: working and debugging. When working, the clamp seat is connected to the spherical bearing assembly via a pin, and the reciprocating transfer of the workpiece is achieved by the rotation of the conjugate cam driving the transfer rocker arm. When debugging, the connecting pin needs to be removed, so that the clamp table assembly and clamp seat assembly can be rotated 90° to facilitate clamp replacement, debugging, and testing operations.

[0003] However, existing technologies lack an effective detection mechanism for the position of the spherical bearing assembly. If the connecting pin is not removed or taken out of the clamp seat slot during debugging, and the motor reducer is started directly, the clamp seat or spherical bearing assembly may be damaged. When lowering the clamp platform assembly, if the spherical bearing assembly is improperly positioned (e.g., located below the clamp seat), it may also damage the relevant components. This lack of detection during operation can easily lead to equipment damage, affecting the equipment's lifespan and working efficiency.

[0004] Therefore, there is an urgent need for a mechanism that can detect the position of the spherical bearing assembly to ensure that the spherical bearing assembly is in the correct position before the clamp table is flipped up or down, so as to avoid equipment damage caused by misoperation and improve the safety and reliability of operation. Utility Model Content

[0005] To solve the above-mentioned technical problems, a clamp platform flipping detection mechanism is provided, which solves the problems existing in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a clamp platform flipping detection mechanism, including a mold box and a clamp platform assembly that can be deflected to one side of the top surface of the mold box. One side of the clamp platform assembly is provided with a reciprocating clamp seat assembly, and the back side of the mold box is provided with a power unit for providing reciprocating movement to the clamp seat assembly.

[0007] The power unit includes an L-shaped conveying rocker arm, the middle part of which is rotatably connected to the mold box via a second rotating shaft, and a transmission joint is provided between the top end of the conveying rocker arm and the clamp seat assembly.

[0008] The mold box is also provided with a limiting part for detecting the position of the transmission joint, and the limiting part is located on the side of the transmission joint.

[0009] Preferably, the limiting part mainly consists of a bracket fixed to the top surface of the mold box and a proximity switch installed on the side of the bracket, with a switch contact provided at the top of the proximity switch.

[0010] Preferably, the top surface of the bracket has a positioning notch that matches the transmission joint.

[0011] Preferably, all four corners of the proximity switch are detachably connected to the bracket by bolts.

[0012] Compared with the prior art, the advantages of this utility model are as follows: By setting the limiting part, when debugging, the transmission section is placed into the positioning notch of the bracket, which presses down the switch contact of the proximity switch. The proximity switch sends an electrical signal to the control system, enabling the geared motor to start and drive the clamp platform assembly to flip up. If the transmission section is not in the positioning notch (i.e., the transmission section is not in the correct position), the switch contact is not pressed down, the proximity switch has no signal output, and the geared motor cannot start, thus avoiding equipment damage. In this way, by utilizing the cooperation between the positioning notch and the proximity switch, the geared motor is ensured to start only when the transmission section is in the correct position, preventing damage to the clamp seat assembly or transmission section due to misoperation (such as the pin not being removed or the transmission section not being deflected), thereby improving the safety of equipment operation.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1-5As shown, a clamp platform flipping detection mechanism includes a mold box 1, a clamp platform assembly 2 that can be deflected to one side of the top surface of the mold box 1, and a reduction motor 5 disposed on the other side of the top surface of the mold box 1. A clamp seat assembly 3 that can reciprocate is provided on one side of the clamp platform assembly 2. A bearing seat 4 is installed in the middle of the top surface of the mold box 1. A rotating shaft is rotatably disposed in the bearing seat 4. One end of the rotating shaft is fixedly connected to the other side of the clamp platform assembly 2, and the other end of the rotating shaft is connected to the output shaft of the reduction motor 5 through a chain drive.

[0022] During debugging, the geared motor 5 is started, and its output shaft drives the rotating shaft to rotate in the bearing seat 4 through the chain belt drive. The rotating shaft transmits power to the clamp table assembly 2, so that it can be flipped up and rotated 90° to facilitate the replacement, debugging and testing of the clamps.

[0023] Furthermore, referring to Figure 2 As shown, it is worth noting that the back side of the mold box 1 is provided with a power unit for providing reciprocating movement for the clamp seat assembly 3;

[0024] The power unit includes an L-shaped conveying rocker arm 6. The middle part of the conveying rocker arm 6 is rotatably connected to the mold box 1 through a rotating shaft 2. A transmission joint 8 is provided between the top of the conveying rocker arm 6 and the clamp seat assembly 3. A servo motor is also provided on the mold box 1. A conjugate cam 7 is fixedly sleeved on the output shaft of the servo motor. The wheel body of the conjugate cam 7 abuts against the side wall at the bottom of the conveying rocker arm 6.

[0025] The conjugate cam 7 is driven to rotate by a servo motor. The contact relationship between the cam profile and the bottom side wall of the conveying rocker arm 6 forces the conveying rocker arm 6 to swing back and forth around the rotation axis. Then, the reciprocating motion of the clamp seat assembly 3 is realized by the transmission joint 8, so as to realize the reciprocating transfer of the workpiece.

[0026] Furthermore, refer to Figure 4 As shown, it is worth noting that the transmission section 8 is composed of a spherical bearing 81 and a double-ended screw 82. The two spherical bearings 81 are respectively connected to the top of the transmission rocker arm 6 and one side of the clamp seat assembly 3 by means of pins. The double-ended screw 82 is assembled between the two spherical bearings 81.

[0027] By setting the transmission joint 8, the spherical bearing 81 allows for multi-angle swinging and rotation between the connecting parts, enabling the transmission rocker arm 6 and the clamp seat assembly 3 to flexibly adjust their angles during relative movement. This avoids jamming or stress concentration caused by rigid connection, ensuring smooth movement and reducing component wear. The double-ended screw 82 can adjust the distance between the two spherical bearings 81 by rotation, facilitating precise matching of the positions of the transmission rocker arm 6 and the clamp seat assembly 3 during installation, ensuring assembly accuracy and improving the reliability of the mechanism.

[0028] During debugging, the connection between the clamp seat assembly 3 and the spherical bearing 81 needs to be disconnected beforehand to start the geared motor 5. When the clamp table assembly 2 is flipped, the transmission section 8 will not interfere with the overall rotation of the clamp seat assembly 3 and the clamp table assembly 2.

[0029] However, the existing mechanism for detecting the position of the transmission joint 8 is not effective. If the operation is improper during debugging, such as the pin connecting the spherical bearing 81 and the clamp seat assembly 3 is not removed or the spherical bearing 81 is not deflected after disassembly, and the geared motor 5 is started directly, the clamp seat assembly 3 or the transmission joint 8 assembly will be damaged. When lowering the clamp platform assembly, if the transmission joint 8 is not in the correct position, such as being below the clamp seat assembly 3, it will also damage the relevant components.

[0030] In view of this, refer to Figure 2 , Figure 3 as well as Figure 5 As shown, it is worth noting that the mold box 1 is also provided with a limiting part 9 for detecting the position of the transmission joint 8. The limiting part 9 is located on the side of the transmission joint 8.

[0031] The limiting part 9 mainly consists of a bracket 91 fixed to the top surface of the mold box 1 and a proximity switch 92 installed on the side of the bracket 91. The top of the proximity switch 92 is provided with a switch contact 93.

[0032] The top surface of the bracket 91 is provided with a positioning notch 94 that is compatible with the transmission joint 8;

[0033] The four corners of the proximity switch 92 are detachably connected to the bracket 91 by bolts.

[0034] By setting the limiting part 9, during debugging, the transmission section 8 is placed into the positioning notch 94 of the bracket 91, which presses down the switch contact 93 of the proximity switch 92. The proximity switch 92 sends an electrical signal to the control system, enabling the geared motor 5 to start and drive the clamp table assembly 2 to flip up. If the transmission section 8 is not in the positioning notch 94, that is, the position of the transmission section 8 is incorrect, the switch contact 93 is not pressed down, the proximity switch 92 has no signal output, and the geared motor 5 cannot start, thus avoiding equipment damage. In this way, by using the cooperation of the positioning notch 94 and the proximity switch 92, the geared motor 5 is only started when the position of the transmission section 8 is correct, preventing damage to the clamp seat assembly 3 or the transmission section 8 due to misoperation such as failure to remove the pin or failure to deflect the transmission section 8, thereby improving the safety of equipment operation.

[0035] Furthermore, the positioning notch 94 can effectively assist in positioning the transmission section 8, preventing interference or abnormal force between the clamping jaw assembly 3 and the transmission section 8 when the motor is started later due to positional deviation or incorrect positioning of the transmission section 8 during the debugging state.

[0036] Furthermore, the proximity switch 92 is detachably connected to the bracket 91 by bolts, which effectively facilitates manual inspection and maintenance of the proximity switch 92.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
