[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0024] Example 1:

[0025] Combine Figure 1-3 As shown, this embodiment provides a workpiece positioning device for a single-station hydraulic drilling machine, including: a main body mechanism 100 and a positioning mechanism 200.

[0026] The main body mechanism 100 includes a base plate 110 , legs 120 symmetrically fixed to the bottom end of the base plate 110 , and an electromagnet 130 installed in the middle of the top end of the base plate 110 .

[0027] The base plate 110 is used to place the workpiece to ensure the stability of the workpiece and is also used to install other components. The legs 120 are fixed on the base plate 110 to support the base plate 110 and ensure the stability of the base plate 110. The electromagnet 130 is used to adsorb and fix the positioned workpiece to ensure the stability of the workpiece during processing. At the same time, the workpiece is magnetically fixed by the electromagnet 130, which facilitates the removal and placement of the workpiece.

[0028] There are two positioning mechanisms, one is set horizontally at the top of the base plate 110, and the other is set vertically at the top of the base plate 110, which are used to position the workpiece horizontally and vertically to ensure that the center point of the workpiece and the center point of the base plate 110 are on the same vertical line.

[0029] The positioning mechanism 200 includes a positioning member 210 that is slidably engaged on the base plate 110, a driving member 220 installed on one side of the base plate 110 and extending into the base plate 110 through the positioning member 210, a sleeve 230 symmetrically fixed on one side of the base plate 110, a laser ranging sensor 240 installed at the end of the sleeve 230 on one side and extending into the sleeve 230, and a control panel 250 installed on one side of the base plate 110.

[0030] Grooves 111 are provided at the top of the base plate 110 in both the horizontal and vertical directions, and slide grooves 112 are provided on both sides of the groove 111 at the top of the base plate 110. At the same time, the positioning member 210 includes a threaded sleeve 212 that is slidably engaged in the groove 111, a baffle 211 fixed at the top of the threaded sleeve 212, and a round rod 213 symmetrically fixed at the bottom end of the baffle 211. The round rod 213 is slidably engaged in the slide groove 112 to ensure the stability of the baffle 211 during movement. The baffle 211 is used to limit the side of the workpiece.

[0031] The driving member 220 includes a threaded rod 221 rotatably installed in the groove 111 and a motor 222 fixed to one side of the base plate 110 and with its shaft fixedly connected to the end of the threaded rod 221. The threaded rod 221 passes through the threaded sleeve 212, and the threaded rod 221 and the threaded sleeve 212 are engaged with each other, so that when the motor 222 rotates, it drives the threaded rod 221 to rotate, and the rotation of the threaded rod 221 drives the threaded sleeve 212 to move, and the movement of the threaded sleeve 212 drives the baffle 211 to move, thereby adjusting the position of the baffle 211.

[0032] The end of the sleeve 230 is connected to the groove 111, and the inner diameter of the sleeve 230 is equal to the diameter of the round rod 213. The end of the round rod 213 extends into the sleeve 230. When the baffle 211 moves, it can drive the end of the round rod 213 to move synchronously in the sleeve 230. The laser ranging sensor 240 is used to monitor the moving distance of the end of the round rod 213 in real time, that is, to monitor the moving distance of the baffle 211, and transmit the monitoring data to the control panel 250.

[0033] The control panel 250 is used to control the position of the baffle 211 to adjust the drive member 220. When in use, the worker inputs the length A of the workpiece into the control panel 250. At this time, the control panel 250 divides the value of the workpiece length A by 2 to calculate the distance between the center point of the workpiece and one side of the workpiece. At the same time, the distance between the baffle 211 and the center point of the base plate 110 is W (with the initial position of the baffle 211 away from the center point of the base plate 110 as the base point). The distance between the baffle 211 and the center point of the base plate 110 is W minus the value of the workpiece length A divided by 2. The moving distance of the baffle 211 when the center point of the workpiece and the center point of the base plate 110 are located on the same vertical line can be calculated. Then, the drive member 220 is started to drive the baffle 211 to move this distance. The adjustment principle of the baffle 211 on the other side is the same as above.

[0034] The working principle and use process of the present invention are as follows: when in use, the length A and width B of the workpiece are input into the control panel 250. At this time, the control panel 250 divides the value of the workpiece length A by 2 to calculate the distance between the center point of the workpiece and one side of the workpiece. At the same time, the distance between the baffle 211 and the center point of the bottom plate 110 is W. The distance between the baffle 211 and the center point of the bottom plate 110 is W minus the value of the workpiece length A divided by 2. The moving distance of the baffle 211 when the center point of the workpiece and the center point of the bottom plate 110 are located on the same vertical line can be calculated. Then, the control panel 250 starts the motor 222. The rotation of the motor 222 drives the threaded rod 221 to rotate. The rotation of the threaded rod 221 drives the threaded sleeve 212 to move. The movement of the threaded sleeve 212 drives the baffle 211 moves, and the baffle 211 moves to the round rod 213 to move. When the round rod 213 moves, the laser ranging sensor 240 monitors the moving distance of the end of the round rod 213 in real time. When the laser ranging sensor 240 detects that the moving distance of the end of the round rod 213 is equal to the moving distance calculated by the control panel 250, the motor 222 is turned off. At this time, the longitudinal positioning member 210 is adjusted. The adjustment of the transverse positioning member 210 is similar. When the transverse and longitudinal positioning members 210 are adjusted, the workpiece is placed on the bottom plate 110 so that one side of the workpiece is in close contact with the longitudinal baffle 211 and the adjacent side is in close contact with the transverse baffle 211. The workpiece positioning can be completed. At this time, the electromagnet 130 is started to magnetically fix the workpiece to ensure the stability of the workpiece.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
