[0026] The present invention will now be described in further detail.
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0028] Combination Figure 1 As shown,
[0029] A high-speed chain positioning disc for automatic gripping of chain links includes two sets of positioning devices. Based on the mirror-image features of the left and right chain links, the two sets of positioning devices are arranged in a mirror image. A mechanical limit pin 5 is designed at the shaft end to prevent the left and right links from being placed in reverse.
[0030] The positioning device on one side of the tooling plate 1 includes a track link shaft hole positioning pin 3, a track link sleeve hole positioning pin 4, and a mechanical limit pin 5 for positioning and limiting the track link. The track link shaft hole positioning pin 3 corresponds to the shaft hole of the track link and is used to position the shaft hole of the track link. The track link sleeve hole positioning pin 4 corresponds to the sleeve hole of the track link and is used to position the sleeve hole of the track link. The mechanical limit pin 5 is used to limit the shaft end of the track link. The mirror arrangement of the mechanical limit pin 5 can also prevent the left and right track links from mixing. The tooling plate 1 is symmetrically provided with lifting holes 6 around its perimeter. The lifting holes 6 provide a positioning position for the lifting mechanism so as to further position the positioning plate when gripping the track link.
[0031] Combination Figure 2 As shown, the tooling plate 1 has equal-width slots 11 on both sides to provide contact points for the blocking mechanism. The tooling plate 1 has a weight-reducing hole 10 in the middle. Both the equal-width slots 11 and the weight-reducing hole 10 can reduce the weight of the positioning plate.
[0032] Combination Figure 3 , Figure 4 As shown, the lifting hole 6 includes a steel sleeve 2. The lower end of the steel sleeve 2 is provided with a flange, and the flange is provided with four screw through holes 9. The bottom of the tooling plate 1 is provided with a countersunk stepped hole, and four M5 threaded holes are provided at the positions corresponding to the screw through holes 9. The steel sleeve 2 is positioned by cooperating with the countersunk stepped hole, and the flange is fixedly connected to the tooling plate 1 by four M5 bolts. The right-angled edge of the steel sleeve 2 is chamfered. Using the steel sleeve 2 helps to improve the wear resistance of the lifting hole 6, and the steel sleeve 2 is easy to replace and has low maintenance cost.
[0033] Combination Figure 5 , Figure 7 As shown, the upper end of the track link shaft hole locating pin 3 is conical with four raised conical surfaces, which are positioned in contact with the track link shaft hole at four points. The lower end of the conical surfaces has a flange, and the lower surface of the track link contacts the upper surface of the flange of the track link shaft hole locating pin 3. The lower end of the track link shaft hole locating pin 3 is a cylinder with a flange, and a corresponding locating hole 7 is provided on the tooling plate 1. The lower cylindrical part of the track link shaft hole locating pin 3 is positioned by engaging the locating hole 7. The surface is pressed into contact with the upper surface of the tooling plate 1; the bottom of the track link shaft hole positioning pin 3 is provided with an axial M10 threaded hole, and a fixing plate 8 is provided on the positioning hole 7 at the bottom of the tooling plate 1. The fixing plate 8 is provided with a flange to prevent the fixing plate 8 from falling into the positioning hole 7. The middle part of the fixing plate 8 is provided with a through hole 9. M10 bolts are used to fasten the threaded hole of the track link shaft hole positioning pin 3 through the through hole 9, thereby fixing the track link shaft hole positioning pin 3 on the tooling plate 1.
[0034] Combination Figure 6As shown, the upper end of the track link sleeve hole positioning pin 4 is a triangular prism tangent to the side of a cone, protruding from three conical sides, and is positioned in contact with the track link sleeve hole at three points. The middle part of the track link sleeve hole positioning pin 4 is provided with a flange for receiving the lower part of the track link. The installation method of the track link sleeve hole positioning pin 4 is the same as that of the track link shaft hole positioning pin 3.
[0035] The advantage of using the fixing plate 8 for screw hoisting of both the track link sleeve hole locating pin 4 and the track link shaft hole locating pin 3 is that the large central screw can be used for fixing, which can enhance the tightness compared to using small screws around the flange, and saves time when replacing the locating pin.
[0036] The height difference between the locating pin 4 of the track link sleeve hole and the locating pin 3 of the track link shaft hole is consistent with the drop difference between the sleeve hole and the shaft hole of the track link. When the track link is laid flat, the axis of the shaft hole and the axis of the sleeve hole are both perpendicular to the locating plate and facing upwards. This makes it convenient for the vertical locating plate to move up / down after the gripper fingers clamp the bolt hole of the track link, which facilitates automatic gripping of the track link.
[0037] This embodiment provides precise positioning for the track links, solving the problem of track link slippage during automated transfer and facilitating the robotic arm's gripping of the track links. Shaft hole / sleeve hole positioning pins address inaccurate track link positioning and slippage during transport; lifting hole 6 ensures precise positioning of the positioning plate, meeting the robotic arm's gripping requirements; based on the mirror-like appearance of the left / right track links, a mechanical limit pin 5 at the shaft end is designed to prevent left / right reversal. The mechanical structure design is simple, the tooling positioning is precise, and it facilitates the robotic arm's gripping of track links perpendicular to the positioning plate. The shaft hole / sleeve hole positioning pins are easy to replace, supporting rapid production changeover.
