[0021] Figure 1 FIG. is a schematic diagram of an embodiment of an automatic feeding and positioning device for drilling of an automotive half shaft in the present invention. As shown in the figure, the present invention provides an automatic feeding and positioning device for drilling of an automotive half shaft,

[0022] which includes a support mechanism 1, a material receiving mechanism 2, a positioning mechanism 3 and a counterweight mechanism 4. The support mechanism 1 is disposed below the material receiving mechanism 2, the positioning mechanism 3 is disposed on the upper side of one end of the material receiving mechanism 2, the counterweight mechanism 4 is disposed on the lower side of the other end of the material receiving mechanism 2, and the positioning mechanism 3 and the counterweight mechanism 4 are symmetrically arranged about the center. The weight of the counterweight mechanism 4 is matched with the weight of the positioning mechanism 3, and the counterweight mechanism 4 and the positioning mechanism 3 are balanced to make the material receiving mechanism 2 in a horizontal state before receiving materials, ensuring the accuracy of material receiving of the material receiving mechanism 2.

[0023] Figure 2 FIG. is a schematic diagram of a support mechanism of an automatic feeding and positioning device for drilling of an automotive half shaft in the present invention. As shown in the figure, the support mechanism 1 includes support legs 101 and a first connecting block 102. The support legs 101 are in an inverted V-shaped structure. A fixing plate 103 is disposed at the bottom of the support legs 101, a first through hole 104 is disposed in the middle of the fixing plate 103, and a connecting member 105 fixedly connected to the ground is inserted through the first through hole 104. The support legs 101 are fixedly connected to the ground through the cooperation of the connecting member 105 and the fixing plate 103, so that the support legs 101 and the ground form a stable triangular structure, thereby improving the stability of the support. The bottom end of the first connecting block 102 is fixedly connected to the top end of the support legs 101, a connecting groove 106 is formed in the middle of the first connecting block 102, a pin shaft 107 is inserted through the middle of the connecting groove 106, and the middle of the material receiving cross beam 201 is inserted into the connecting groove 106 and hinged to the pin shaft 107, enabling the material receiving cross beam 201 to rotate in the connecting groove 106, thereby facilitating the material receiving cross beam 201 to deflect according to the weight of the half shaft.

[0024] Figure 3 This is a schematic diagram of the receiving pulley of the automatic feeding and positioning device for drilling the automotive half shaft in the present invention. As shown in the figure, the receiving mechanism 2 includes a receiving cross beam 201 and receiving pulleys 202. A plurality of receiving pulleys 202 are symmetrically arranged, and the plurality of receiving pulleys 202 are symmetrically arranged on the upper side of the receiving cross beam 201. A plurality of U-shaped fixing members 203 are fixedly connected to the upper side of the receiving cross beam 201. The receiving pulleys 202 are arranged in the middle of the fixing members 203. The receiving pulleys 202 are connected to the fixing members 203 through rotating shafts 204 to ensure the smooth rotation of the receiving pulleys 202, thus facilitating the movement of the half shaft. A V-shaped receiving groove 205 is arranged in the middle of the receiving pulley 202. The half shaft falls from the end of the conveying device onto the receiving mechanism 2, and the V-shaped receiving groove 205 limits it to prevent it from slipping and ensures the stability of the half shaft positioning.

[0025] Figure 4 This is a schematic diagram of the positioning plate of the automatic feeding and positioning device for drilling the automotive half shaft in the present invention. As shown in the figure, the positioning mechanism 3 includes a positioning plate 301 and a sensing device 302. The position where the positioning plate 301 is connected to the receiving cross beam 201 can be installed according to actual needs. An arc-shaped positioning hole 303 is opened in the middle of the positioning plate 301. A sensing device 302 is arranged on the side of the positioning plate 301 away from the receiving pulley 202. The sensing device 302 can be a weight sensor, and the sensing device 302 is electrically connected to the grasping device. Since the flange at one end of the half shaft is heavier, when the half shaft falls into the receiving mechanism 2, the end of the half shaft connected to the flange is heavier and tilts downward, and the half shaft moves along with the receiving pulley 202 towards the side of the positioning mechanism 3 until the end face of the flange contacts the positioning plate 301. Then, after the sensing device 302 detects the half shaft, it transmits the sensing signal to the grasping device, and the grasping device grasps the half shaft after receiving the sensing signal.

[0026] The counterweight mechanism 4 includes a second connecting block 401, a hook 402, and a counterweight 403. The second connecting block 401 is fixedly connected to the lower side of the receiving cross beam 201. A second through hole is arranged on the second connecting block 401. The hook 402 is arranged on the top of the counterweight 403, and the hook 402 is inserted and connected to the second through hole, which is convenient for replacing the counterweight 403. The counterweight mechanism 4 balances the positioning mechanism 3 and also reduces the impact force when the receiving mechanism 2 contacts the product for the first time, avoids the positioning device from being damaged by impact, and prolongs the service life of the positioning device.

[0027] Specific usage process: Install the above positioning device at the end of the conveying device, with the positioning mechanism 3 facing one end of the half shaft flange. The half shaft falls onto the receiving mechanism 2 through the conveying device. The half shaft falls into the receiving groove of the receiving pulley 202. The weight of the flange end is relatively heavy, so that the receiving cross beam 201 rotates relative to the first connecting block 102, causing the half shaft to move on the receiving cross beam 201 and making the flange contact the positioning plate 301, thereby achieving precise positioning of the flange end of the half shaft. After the sensing device 302 detects the half shaft, it transmits the sensing signal to the grasping device. After receiving the sensing signal, the grasping device grasps the half shaft to achieve precise clamping, and then conveys the half shaft to the next station for drilling processing of the half shaft flange.

[0028] Therefore, the automatic loading and positioning device for drilling processing of automotive half shafts with the above structure according to the present invention has a simple structure, can precisely position half shaft products, facilitates the grasping device to grasp at a precise position, improves work efficiency, and saves manpower.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
