[0037] In some embodiments of the present invention, the conveying device further includes two pallets 231, the two pallets 231 are arranged at intervals on the left and right, the conveyor belt has an upper belt segment 210, the two pallets 231 are stacked at the bottom of the upper belt segment 210, and the lifting mechanism is arranged between the two pallets 231. It can be understood that when in use, multiple workpieces need to be placed on the upper side of the conveyor belt, and the upper belt segment 210 of the conveyor belt is a flexible component, which will deform when supporting objects with a large mass, resulting in the workpiece cannot be accurately transported to the transfer station; in this embodiment, by setting two pallets 231, the two pallets 231 are fixedly arranged on the support frame 200, and the two pallets 231 can support the parts of the upper belt segment 210 located on the left and right sides of the transfer station, so that the upper belt segment 210 can stably transport the workpiece. The belt body of the conveyor belt can extend downward from the right end of the upper belt segment 210, and then cross under the jacking mechanism and the two support plates 231 and connect to the left end of the upper belt segment 210; wherein, an intermediate connecting plate 233 can also be connected between the two support plates 231, and the intermediate connecting plate 233 is stacked on the lower side of the upper belt segment 210, and the front and rear dimensions of the intermediate connecting plate 233 are not larger than the front and rear dimensions of the upper belt segment 210, and the intermediate connecting plate 233 and the two support plates 231 can be an integral component, so that the intermediate connecting plate 233 can support and support the upper belt segment 210 at the transfer station.

[0038] In some embodiments of the present invention, the front-to-back dimension of the support plate 231 is not less than the front-to-back dimension of the tapping station, and the front and rear edges of the support plate 231 are both provided with convex edges 232 protruding upward. When the workpiece is placed on the upper side of the support plate 231, the workpiece is located between the two convex edges 232, and the two convex edges 232 can limit the front-to-back position of the workpiece, preventing the workpiece from shifting forward or backward when being transported, so that the workpiece can move laterally stably.

[0039] In some embodiments of the present invention, the clamping device further includes a stopper 244 disposed on the right side of the tapping station, a horizontal pusher 245 disposed on the left side of the tapping station, and a second driving mechanism 246 for driving the horizontal pusher 245 to move horizontally. After the lifting mechanism lifts the workpiece from the transfer station, the second driving mechanism 246 drives the horizontal pusher 245 from left to right to press the workpiece against the stopper 244 to position the horizontal position of the workpiece, which is beneficial to improving the processing accuracy.

[0040] Among them, the number of the stop blocks 244 can be two, and the two stop blocks 244 are respectively arranged on the right front side and the right rear side of the tapping station, and the two stop blocks 244 are respectively hinged to the base 240 through a vertically arranged hinge shaft, and a tension spring 243 is connected between the two stop blocks 244; the two stop blocks 244 are arranged in front and back mirror symmetry, taking the stop block 244 located on the front side as an example, the stop block 244 has a blocking part arranged on the rear side of the hinge shaft and a side leaning part located on the left side of the hinge shaft, and the tension spring 243 is connected to the right front side of the hinge shaft; when the second driving mechanism 246 drives the horizontal pushing block 245 to the right and then drives the workpiece to move right, the two ends of the workpiece push the blocking parts of the two stop blocks 244 from left to right, so that the side leaning parts of the two stop blocks 244 clamp the workpiece 001 along the front and back directions, and at the same time complete the positioning of the workpiece in the front and back directions; the second driving mechanism 246 can be a cylinder arranged on the base 240.

It can be understood that in order to avoid hindering the movement of the workpiece in the conveyor belt sauna, the distance between the two convex edges 232 will be greater than the front and rear dimensions of the workpiece, which will cause a certain front and rear position offset when the workpiece is transported horizontally by the conveyor belt; this embodiment can preliminarily locate the front and rear position of the workpiece at the transfer station, and then send it to the tapping station. Of course, the third driving mechanism may also include only one third linear driver 250, and the two longitudinal stops 251 can be moved closer to or farther from each other at the same time through a linkage mechanism.

[0042] In some embodiments of the present invention, the conveying device also includes two horizontal rest stops 261 and a fourth driving mechanism for driving the two horizontal rest stops 261 to move vertically. The conveying direction of the conveyor belt is toward the right. The two horizontal rest stops 261 are both arranged on the right side of the transfer station, and the two horizontal rest stops 261 are respectively arranged on the front and rear sides of the conveyor belt. When the workpiece needs to be transported to the right from the transfer station after tapping, the fourth driving mechanism drives the two transverse stops 261 to move downward; before the workpiece to be tapped moves to the transfer station, the fourth driving mechanism drives the two transverse stops 261 to move upward, so that the two ends of the workpiece will abut against the two transverse stops 261 from left to right during the workpiece transportation process, and the lateral position of the workpiece is preliminarily positioned; the fourth driving mechanism includes a fourth linear drive 260, and the fourth linear drive 260 can be a cylinder, a hydraulic cylinder, an electric push rod or other suitable drives.

[0045] In some embodiments of the present invention, there are multiple taps 123, and the base 240 is provided with an avoidance through hole 242 corresponding to each tap 123. The gear box 120 can be provided with multiple output shafts to drive multiple taps 123. In this way, multiple positions can be tapped at the same time, thereby improving efficiency.

[0046] In some embodiments of the present invention, a groove 241 is provided on the top surface of the base 240, and all the avoidance through holes 242 are provided in the groove 241; a liquid outlet pipe 220 for supplying tapping liquid is provided on the upper side of the base 240, and the liquid outlet pipe 220 is arranged toward the groove 241. It should be noted that during tapping, it is necessary to continuously spray tapping liquid onto the taps 123.
