[0031] The following is for reference. Figures 1 to 6 This invention describes a continuous tapping device according to an embodiment of the present invention.

[0032] The continuous tapping equipment of this utility model includes a base frame 100, a tapping device, a conveying device, and a clamping device.

[0033] The tapping device includes a vertically arranged tap 123, a first drive mechanism for driving the tap 123 to rotate, and a fifth drive mechanism for driving the tap 123 to move vertically. A tapping station is located below the tap 123. The fifth drive mechanism includes a lifting seat 110 and a fifth linear actuator 111. The lifting seat 110 is slidably mounted vertically on a base frame 100. The rear side of the lifting seat 110 is connected to the base frame 100 via a guide rail slider mechanism or other suitable sliding mechanism to achieve a vertical sliding connection. The fifth linear actuator 111 can be a cylinder, hydraulic cylinder, electric actuator, or other suitable actuator. The fifth linear actuator 111 drives the lifting seat 110 to move vertically, thereby driving the gearbox 120, the first rotary actuator 121, and the tap 123. The movement is vertical; the first drive mechanism is connected to the top of the tap 123. The first drive mechanism includes a first rotary driver 121 and a gearbox 120. The gearbox 120 is fixedly installed on the front side of the lifting seat 110. The first rotary driver 121 is installed on the upper side of the gearbox 120. The first rotary driver 121 can be an electric motor. The top of the gearbox 120 is provided with an input shaft, which is linked to the power shaft of the first rotary driver 121, so that the first rotary driver 121 can be used as the power input of the gearbox 120. The tap 123 is installed on the lower side of the gearbox 120. The bottom of the gearbox 120 is provided with an output shaft, which is linked to the tap 123, so that the power output of the gearbox 120 can act on the tap 123, thereby causing the tap 123 to rotate.

[0034] The conveying device includes a transversely extending conveyor belt, with a transfer station located on the upper side of the conveyor belt and below the tapping station. The front-to-back dimensions of the transfer station are larger than those of the conveyor belt. The conveyor belt includes a support frame 200 and a belt body disposed on the support frame 200. The support frame 200 is fixedly disposed relative to the base frame 100. The belt body is annular and has an upper belt section 210 located below the transfer station. The upper belt section 210 conveys from left to right.

[0035] The clamping device includes a base 240 located above the tapping station and a lifting mechanism located below the transfer station. The lifting mechanism drives the workpiece 001 located at the transfer station to move vertically. The base 240 is fixedly mounted on the support frame 200 and is positioned between the tap 123 and the tapping station. A clearance area is provided below the tap 123 on the base 240 to prevent the base 240 from obstructing the downward movement of the tap 123. The lifting mechanism includes two lifting blocks 271 located at the lower front and lower rear sides of the transfer station, respectively. An upper belt section 210 is positioned between the two lifting blocks 271. The lifting mechanism also includes a lifting linear actuator 270, which can be a cylinder, hydraulic cylinder, electric actuator, or other suitable actuator. The number can be one, in which case the two lifting blocks 271 are driven to rise and fall by the same lifting linear driver 270. The number of lifting linear drivers 270 can also be two, in which case the two lifting linear drivers 270 are connected to the two lifting blocks 271 in a one-to-one correspondence. This embodiment is applicable to workpieces whose front and rear dimensions are larger than the conveyor belt, such as the heat sealing knife of a sealing machine. The heat sealing knife is strip-shaped. When the heat sealing knife is placed in the transfer station, its front end and rear end extend above the two lifting blocks 271 respectively. The rise of the two lifting blocks 271 can drive the heat sealing knife to rise and abut against the bottom of the base 240 to achieve the vertical positioning of the heat sealing knife.

[0036] In use, multiple workpieces can be placed sequentially on the upper side of the conveyor belt along the horizontal direction. The conveyor belt transports the workpieces to the transfer station, and then the lifting mechanism lifts the workpieces to the tapping station. The tap 123 of the tapping device then moves down to tap the workpiece. After tapping is completed, the tap 123 is reset, the lifting mechanism moves the workpiece down to the transfer station, and then the conveyor belt transports the next workpiece to the transfer station to tap the next workpiece. This cycle is repeated to continuously tap multiple workpieces. The operator only needs to place new workpieces on the upper side of the conveyor belt, without having to load or unload workpieces from the fixture, reducing manpower consumption and improving production efficiency.

[0037] In some embodiments of this utility model, the conveying device further includes two pallets 231, which are spaced apart from each other. The conveyor belt has an upper belt section 210, and the two pallets 231 are stacked on the bottom of the upper belt section 210. A lifting mechanism is located between the two pallets 231. It is understood that multiple workpieces need to be placed on the upper side of the conveyor belt during use. However, the upper belt section 210 is a flexible component, which will deform when supporting heavy objects, causing the workpieces to be unable to be accurately conveyed to the transfer station. In this embodiment, by setting two pallets 231, both of which are fixedly mounted on the support frame 200, the two pallets 231 can support the portions of the upper belt section 210 located on the left and right sides of the transfer station, enabling the upper belt section 210 to stably convey the workpieces. The conveyor belt can extend downward from the right end of the upper belt segment 210, then pass under the lifting mechanism and the two pallets 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 pallets 231, the intermediate connecting plate 233 is stacked on the lower side of the upper belt segment 210, the front-to-back dimension of the intermediate connecting plate 233 is not greater than the front-to-back dimension of the upper belt segment 210, and the intermediate connecting plate 233 and the two pallets 231 can be an integral component, so that the intermediate connecting plate 233 can support the upper belt segment 210 at the transfer station.

[0038] In some embodiments of this utility model, the front-to-back dimensions of the pallet 231 are not less than the front-to-back dimensions of the tapping station, and the front and rear edges of the pallet 231 are provided with upwardly protruding edges 232. When the workpiece is placed on the upper side of the pallet 231, the workpiece is located between the two protruding edges 232. The two protruding edges 232 can restrict the front-to-back position of the workpiece, prevent the workpiece from shifting forward or backward when being transported, and enable the workpiece to move laterally stably.

[0039] In some embodiments of this utility model, the clamping device further includes a stop 244 located on the right side of the tapping station, a transverse push block 245 located on the left side of the tapping station, and a second drive mechanism 246 for driving the transverse push block 245 to move laterally. After the lifting mechanism lifts the workpiece from the transfer station, the second drive mechanism 246 drives the transverse push block 245 from left to right to press the workpiece against the stop 244, thereby positioning the lateral position of the workpiece and improving machining accuracy.

[0040] The number of stops 244 can be two, with the two stops 244 respectively located on the right front side and right rear side of the tapping station. The two stops 244 are hinged to the base 240 by vertically arranged hinge shafts, and a tension spring 243 connects the two stops 244. The two stops 244 are arranged in a mirror image symmetrical arrangement. Taking the stop 244 located on the front side as an example, the stop 244 has a blocking part located on the rear side of the hinge shaft and a side resting part located on the left side of the hinge shaft. The tension spring 243 is connected to the right front side of the hinge shaft. When the second drive mechanism 246 drives the horizontal push block 245 to the right and thus drives the workpiece to move to the right, the two ends of the workpiece push the blocking parts of the two stops 244 from left to right, so that the side resting parts of the two stops 244 clamp the workpiece 001 in the front-back direction, and at the same time complete the positioning of the workpiece in the front-back direction. The second drive mechanism 246 can be a cylinder set on the base 240.

[0041] In some embodiments of this utility model, the conveying device further includes a third drive mechanism and two longitudinal stops 251. The two longitudinal stops 251 are respectively located on the front and rear sides of the transfer station. The third drive mechanism is used to drive the two longitudinal stops 251 to move closer to or further away from each other. The third drive mechanism includes two third linear actuators 250. The third linear actuators 250 can be cylinders mounted on the support frame 200. The two third linear actuators 250 are connected to the two longitudinal stops 251 one-to-one. The longitudinal stops 251 are columnar extending forward and backward. The end of the longitudinal stop 251 facing away from the transfer station is connected to the third linear actuator 250. It can be understood that, in order to avoid hindering the movement of the workpiece on the conveyor belt, the distance between the two protruding edges 232 will be greater than the front-back dimension of the workpiece. This results in a certain front-back position offset when the workpiece is transported laterally by the conveyor belt. This embodiment can perform preliminary positioning of the front-back position of the workpiece at the transfer station before sending it to the tapping station. Of course, the third drive mechanism may also include only one third linear drive 250, and the two longitudinal stops 251 can move closer or further apart from each other at the same time through a linkage mechanism.

[0042] In some embodiments of this utility model, the conveying device further includes two horizontal stops 261 and a fourth driving mechanism for driving the two horizontal stops 261 to move vertically. The conveying direction of the conveyor belt is to the right. The two horizontal stops 261 are both located on the right side of the transfer station. The two horizontal stops 261 are respectively located on the front and rear sides of the conveyor belt. When the workpiece is finished tapping and needs to be transported to the right from the transfer station, the fourth drive mechanism drives the two horizontal stops 261 to move downwards. Before the workpiece is moved to the transfer station, the fourth drive mechanism drives the two horizontal stops 261 to move upwards, so that the two ends of the workpiece will abut against the two horizontal stops 261 from left to right during the workpiece transport process, and the lateral position of the workpiece is initially positioned. The fourth drive mechanism includes a fourth linear actuator 260, which can be a cylinder, hydraulic cylinder, electric push rod or other suitable actuator. There can be one fourth linear actuator 260, in which case the two horizontal stops 261 are driven to rise and fall by the same fourth linear actuator 260. There can also be two fourth linear actuators 260, in which case the two fourth linear actuators 260 are connected to the two horizontal stops 261 in a one-to-one correspondence.

[0043] The operation process of the continuous tapping equipment is as follows: the workpiece is placed on the left side of the upper belt section 210. The upper belt section 210 drives the workpiece to move to the right and close to the transfer station. The fourth drive mechanism drives the two horizontal stops 261 to rise. The upper belt section 210 drives the workpiece to continue to move to the right, so that the front and rear ends of the workpiece abut against the two horizontal stops 261 respectively. The third drive mechanism drives the two vertical stops 251 to move closer to each other and perform preliminary positioning of the workpiece in the front and rear direction. The lifting mechanism drives the two lifting blocks 271 to rise, so that the workpiece rises. The fourth drive mechanism drives the two horizontal stops 261 to fall. The third drive mechanism drives the two vertical stops 251 to move away from each other. The second drive mechanism 246 drives the horizontal push block 245 to move to the right, so that the front and rear ends of the workpiece abut against the two stops 244 respectively. The first drive mechanism drives the tap 123 to rotate. The fifth drive mechanism drives the tap 123 to move downward to complete the tapping.

[0044] In some embodiments of this utility model, the base 240 is provided with a vertically extending clearance through hole 242, which is located below the tap 123. The base 240 is a horizontally arranged plate, and the front and rear ends of the base 240 are fixedly mounted on the support frame 200. In this way, the top surface of the workpiece can abut against the bottom surface of the base 240 during tapping, and the workpiece is clamped and fixed more firmly.

[0045] In some embodiments of this invention, there are multiple taps 123, and the base 240 is provided with a clearance through hole 242 for each tap 123. The gearbox 120 can be provided with multiple output shafts to drive multiple taps 123. This allows for simultaneous tapping at multiple positions, improving efficiency.

[0046] In some embodiments of this utility model, the top surface of the base 240 is provided with a groove 241, and all the clearance through holes 242 are provided in the groove 241; the upper side of the base 240 is provided with a liquid outlet pipe 220 for supplying tapping fluid, and the liquid outlet pipe 220 is set towards the groove 241. It should be noted that during tapping, tapping fluid needs to be continuously sprayed onto the tap 123. In related technologies, an independent spray pipe must be set on the side of each tap 123, which is very inconvenient; in this embodiment, by setting the groove 241, the tapping fluid sprayed from the liquid outlet pipe 220 can be collected in the groove 241, so that tapping fluid flows in each clearance through hole 242, achieving the purpose of supplying tapping fluid to multiple taps 123 with only one liquid outlet pipe 220; the continuous tapping equipment also includes a tapping fluid circulation system, which includes a liquid outlet pipe 220 that can spray tapping fluid. The tapping fluid circulation system is a conventional device in the art, and its specific structure will not be described in detail here.

[0047] In some embodiments of this utility model, the tapping device further includes a floating shank 122, which is connected between the first drive mechanism and the tap 123. By setting the floating shank 122, the problem of the tap 123 breaking during tapping due to workpiece positioning errors is avoided.

[0048] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
