Castings have very low precision and surface roughness, making positioning, gripping, and process transfer difficult in the machining process. Generally, loading during machining requires a robot paired with a gripper. Currently, the mainstream gripping solution uses dual cylinders for clamping, resulting in poor positioning accuracy.

[0027] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0028] Example: A single-cylinder gripping device for a flat wire motor housing, see attached document. Figure 1 -Appendix Figure 4 The system includes a support base 1, a sliding base 2, a cylinder 5, clamping fingers 22, and a hydraulic buffer 3. The support base 1 is connected to the robot arm. There are two sliding bases 2, and the two sliding bases 2 can slide along the length of the support base 1 at the bottom. The cylinder body and piston rod of the cylinder 5 are respectively connected to the two sliding bases 2. There are two clamping fingers 22, which are respectively fixedly connected to the side of the two sliding bases 2 away from the support base 1. There are two hydraulic buffers 3, which are respectively located on the side of the two sliding bases 2 that are close to each other. When the two sliding bases 2 slide towards each other, they squeeze the two hydraulic buffers 3 respectively. The middle position between the two hydraulic buffers 3 is located at the middle position of the length of the support base 1.

[0029] With the two hydraulic buffers 3 in place, when the clamping finger 22 clamps the motor housing, if the pressure on the two hydraulic buffers 3 is unbalanced, it will push the two sliding seats 2 to slide on the support seat 1 so that the middle position of the motor housing is aligned with the middle position of the support seat 1 in the length direction, so as to achieve precise positioning of the motor housing.

[0030] Specifically, the hydraulic damper 3 includes a receiving cavity 31 and a squeezing rod 32. The receiving cavity 31 is filled with hydraulic oil. The squeezing rod 32 is located at one end of the receiving cavity 31 near the sliding seat 2. The end of the squeezing rod 32 away from the sliding seat 2 is inserted into the receiving cavity 31 and can slide in the receiving cavity 31 along the sliding direction of the sliding seat 2 to squeeze the hydraulic oil in the receiving cavity 31.

[0031] Specifically, the bottom of the support base 1 is fixedly connected to two slide rails 11 located near the two sides of the support base 1; each slide base 2 is provided with two sets of sliders 21 corresponding to the two slide rails 11 respectively. The sliders 21 can slide on the slide rails 11 along the sliding direction of the slide base 2, and each set of sliders 21 is provided with at least one slider.

[0032] Specifically, this embodiment also includes a positioning mechanism 4. There are two positioning mechanisms 4, which are respectively located on both sides of the bottom of the support base 1 and on the two sides of the slide rails 11 that are far apart from each other.

[0033] Specifically, the positioning mechanism 4 includes a fixed block 41, a positioning rod 42, a spring 43, and a proximity switch 44. The fixed block 41 is provided with a clearance hole 411 that passes through the fixed block 41 along the width direction of the support base 1. The positioning rod 42 is located at the bottom of the fixed block 41, and one of its top ends extends upward into the clearance hole 411. The positioning rod 42 can slide up and down on the fixed block 41. The spring 43 is sleeved on the outside of the positioning rod 42. One of the bottom ends of the spring 43 is fixedly connected to the outside of the positioning rod 42 near the bottom, and the top end is fixedly connected to the bottom of the fixed block 41. The proximity switch 44 is fixedly connected in the clearance groove.

[0034] With the positioning mechanism 4 in place, when the support base 1 moves downwards towards the motor housing, the bottom of the positioning rod 42 first contacts the motor housing, and then pushes the positioning rod 42 upwards. When the top end of the positioning rod 42 approaches the proximity switch 44, the motor housing is located between the two clamping fingers 22. At this time, the proximity switch 44 transmits a signal to the cylinder 5, and the cylinder 5 begins to drive the two clamping fingers 22 to move towards each other to clamp the motor housing.

[0035] Specifically, the cylinder 5 is positioned above the support base 1, and the support base 1 has through holes corresponding to the positions of the two sliding seats 2. The support base 1 is provided with a connecting block that passes through the through holes and connects to the cylinder 5. The through holes provide sufficient space for the movement of the connecting block.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
