The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments. Example

[0027] like Figures 1 to 6As shown, the utility model provides a connector needle body opening chamfering device, including a frame 1 and a vibration plate 2, a linear vibration feeder 3, a clamping mechanism 4 and a processing module 5 installed on the frame 1, the discharge port of the vibration plate 2 is docked with the feed port of the linear vibration feeder 3, the clamping mechanism 4 is arranged on one side of the linear vibration feeder 3, the processing module 5 includes a mounting seat 51, a feeding mechanism 52, a feeding mechanism 53, a processing shaft 54, a processing top block 55, a displacement motor 56, a processing motor 57 and a displacement screw 58 and a processing screw 59 arranged vertically and crosswise in the horizontal direction, the feeding mechanism 52, the feeding mechanism 53 and the processing shaft 54 ​​are fixedly installed on the mounting seat 51; the front end of the processing shaft 54 ​​is provided with a tool The chuck 541, the processing axis 54 is connected to the resetting member 542 for resetting, and the processing axis realizes different functions by installing different tools. In this embodiment, the processing axis is divided into a hole-guiding axis, a drilling axis and a chamfering axis; the displacement screw 58 is respectively connected to the displacement motor 56 and the mounting seat 51, and the processing top block 55 is arranged opposite to the clamping end of the clamping mechanism 4, and the processing screw 59 is respectively connected to the processing motor 57 and the processing top block 55. The displacement motor 56 drives the various components on the mounting seat 51 to move along the width direction of the frame through the displacement screw 58, and the processing motor 57 drives the processing top block 55 to move toward the clamping end of the clamping mechanism 4 through the processing screw 59, and the processing axis 54 and the processing top block 55 are on the same horizontal plane.

[0028] Furthermore, in order to improve the transmission efficiency, two slide rails can be installed on the frame respectively, and the mounting seat 51 and the processing top block 55 can be fixedly installed on the slider respectively, and the transmission efficiency is effectively improved through the transmission connection of the slide rail and the slider.

[0029] Furthermore, in order to realize automatic control, a controller 9 is also installed on the frame 1, and the controller 9 is electrically connected to the vibration plate 2, the linear vibration feeder 3, the clamping mechanism 4 and the processing module 5 respectively, so that the start and stop of each mechanism can be uniformly controlled by the controller 9.

[0030] Specifically, Figure 4As shown, the reset member 542 includes a reset spring 5421, a guide shaft 5422 and a connecting block 5423. The connecting block 5423 connects the processing shaft 54 ​​and the guide shaft 5422 respectively. The guide shaft 5422 is sleeved with a bushing 5424 and a reset spring 5421. The bushing 5424 is provided with a boss, one end of the boss abuts against the connecting block 5423, and the other end abuts against the reset spring 5421. After the processing top block 55 pushes the processing shaft 54 ​​to process the product on the clamping mechanism 4, the processing motor 57 drives the processing top block 55 to retract, and the processing shaft 54 ​​also retracts to the initial position under the action of the reset spring. Furthermore, an eccentric sleeve 543 is sleeved on the processing shaft 54, and the height of the processing shaft 54 ​​is adjusted by rotating the eccentric sleeve 543, so that the tool is placed in a suitable cutting position.

[0031] Working principle: the products to be processed are manually placed on the vibration plate 2. Under the action of the vibration plate 2 and the linear vibration feeder 3, the products to be processed are arranged in a straight line and sent out from the discharge end of the linear vibration feeder 3. The loading mechanism 52 takes the materials and moves them to the clamping end of the clamping mechanism 4 for further loading.

The fixed length shaft 525 is coaxially arranged with the center of the material taking clamping claw 523. By setting the fixed length cylinder 524 and the fixed length shaft 525, when the front and rear cylinder 521 transports the product to the clamping mechanism 4, the fixed length cylinder 524 drives the fixed length shaft 525 to move toward the clamping end of the clamping mechanism 4, thereby pushing the product to a defined clamping position, preventing the product from having a processing error due to unstable clamping, and affecting the product qualification rate. Example

[0033] like Figure 5As shown, the clamping mechanism 4 includes a machine tool spindle box 41 and a clamping cylinder 42, a chuck pull rod 43, a product chuck 44 and a pull rod swing block 45 installed in the machine tool spindle box 41.

When the sensor 33 senses that the feeding mechanism 52 is close to the material, the blocking cylinder 31 drives the blocking block 32 to retreat, and the feeding mechanism 52 takes the material, so as to prevent the product from falling from the discharge port of the linear vibration feeder 3 and reduce the trouble of secondary feeding.

[0036] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
