A positioning device is also provided on the machine table, and the positioning device is used to intermittently lock the material tray. When the material tray is locked, the loading device, the punching device and the unloading device can all cooperate with the corresponding mold base at the same time.

By adopting the above technical scheme: the valve block shallow groove processing equipment has a material tray that cooperates with the loading, stamping and unloading stations, and the rotary motor drives the material tray to pass through the loading device, the stamping device and the unloading device in sequence. The loading device is used to place the workpiece on the die base of the material tray, and the stamping device is used to stamp or punch the workpiece on the die base, and then the unloading device takes away the punched workpiece. The rotary motor drives the material tray to realize intermittent rotation under the action of the positioning device, thereby ensuring that the loading, stamping and unloading work can be carried out smoothly. The use of this equipment reduces manual participation, improves the degree of automation, and thus realizes the efficient production of valve blocks.

The positioning device includes a ring seat, a support seat is provided on the machine platform, the material tray is rotatably connected to the support seat, the ring seat is rotatably arranged on the upper end surface of the support seat, an elastic positioning component is fixed on the ring seat, a positioning groove adapted to the elastic positioning component is opened on the inner side of the material tray, a driving gear is provided on the support seat, a gear ring meshingly connected to the driving gear is provided on the inner ring of the ring seat, and a rotating motor connected to the driving gear power is provided in the support cylinder.

By adopting the above technical solution: the ring seat is rotatably installed on the support seat. When the material tray is replaced, the number of mold seats may change. At this time, the position of the original elastic positioning component cannot cooperate with the replaced material tray. At this time, the rotating motor can be started to let the driving gear drive the ring gear to rotate, thereby adjusting the position of the elastic positioning component to ensure that the material tray can cooperate with the elastic positioning component after replacement.

The elastic positioning assembly includes a fixed cylinder, one end of which is provided with a guide groove, a telescopic cylinder is slidably inserted in the guide groove, and a spring is provided in the guide groove to resist the inner end of the telescopic cylinder, an installation groove is provided at the outer end of the telescopic cylinder, an automatic telescopic rod is installed in the installation groove, one end of the automatic telescopic rod is connected to a positioning block, the positioning block has a head and a guide part, the guide part is slidably connected to the inner wall of the installation groove, the telescopic cylinder has a slope at the notch of the installation groove, and the notch of the positioning groove is set to a reverse slope that matches the notch of the installation groove.

By adopting the above technical solution: the automatic telescopic rod of the elastic positioning component does not work during the rotation of the material tray. At this time, the slope of the telescopic cylinder in the elastic positioning component at the notch of the installation groove is coordinated with the reverse slope of the positioning groove on the material tray, so that the material tray can stop at the specified position. At this time, the automatic telescopic rod is started, and after the automatic telescopic rod is extended, the guide block connected to one end of the rod continues to extend into the positioning groove, thereby achieving a secondary positioning effect, ensuring that the material tray can complete the corresponding operation at the specified position, and the reliability of the equipment is improved by the positioning device.

During the clamping work, any die base of the material tray needs to reach the position of the stamping device. Secondly, the workpiece is pressed on the die base by the axial extension end of the clamping cylinder, and then the punching cylinder is started to drive the punching rod to move. The punching rod cooperates with the punching hole on the die base from the bottom of the die base to complete the stamping or punching work of the workpiece. After the stamping or punching work is completed, the punching rod retreats first, and then the axial extension end of the clamping cylinder retreats, and the material tray rotates to the next process.

The machine platform is provided with a spare punching device with the same structure as the punching device. There are at least four die seats on the material tray. The spare punching device is arranged adjacent to the punching device. When the positioning device locks the material tray, the material tray has a die seat that cooperates with the spare punching device.

A material tray 2 is rotatably arranged on the machine table 1, and the driving device is used to drive the material tray 2 to rotate. A mold base 201 is arranged in a circular array on the material tray 2. A loading device, a punching device and a unloading device are arranged on the machine table 1 in sequence according to the rotation direction of the material tray 2. The driving device includes a rotary motor 7 arranged on the machine table 1. The rotary motor 7 is installed inside the machine table 1 and the output end of the rotary motor 7 extends upward from the end face of the machine table 1 and is fixedly connected to the center of the material tray 2. The machine table 1 also has a positioning device, which is used to intermittently lock the material tray 2. When the material tray 2 is locked, the loading device, the punching device and the unloading device can all cooperate with the corresponding mold base 201 at the same time. The valve block shallow groove processing equipment of this embodiment has a material tray 2 that cooperates with the loading, stamping and unloading stations. The rotary motor 7 drives the material tray 2 to pass through the loading device, the stamping device and the unloading device in sequence. The loading device is used to place the workpiece 8 on the die base 201 of the material tray 2, and the stamping device is used to stamp or punch the workpiece 8 on the die base 201. Then the unloading device takes away the stamped workpiece 8. The rotary motor 7 drives the material tray 2 to realize intermittent rotation under the action of the positioning device, thereby ensuring that the loading, stamping and unloading work can be carried out smoothly. The use of this equipment reduces manual participation, improves the degree of automation, and thus realizes efficient production of valve blocks.

Specifically, as shown in FIG2 , the positioning device of this embodiment includes a ring seat 18, a support seat 16 is provided on the machine 1, the material tray 2 is rotatably connected to the support seat 16, the ring seat 18 is rotatably arranged on the upper end surface of the support seat 16, an elastic positioning component is fixed on the ring seat 18, a positioning groove 202 adapted to the elastic positioning component is provided on the inner side of the material tray 2, a driving gear 21 is provided on the support seat 16, a gear ring 20 meshingly connected to the driving gear 21 is provided on the inner ring of the ring seat 18, and a rotating motor connected to the driving gear 21 is provided in the support cylinder. Since the ring seat 18 is rotatably installed on the support seat 16, when the material tray 2 is replaced, the number of mold bases 201 may change. At this time, the position of the original elastic positioning component cannot be matched with the replaced material tray 2. At this time, the rotating motor can be started to allow the driving gear 21 to drive the gear ring 20 to rotate, thereby adjusting the position of the elastic positioning component to ensure that the material tray 2 can be matched with the elastic positioning component after replacement.

As shown in FIG2 , an output shaft 19 extends out from the center of the support seat 16, and the output shaft 19 and the support seat 16 are rotatably matched, and a spline groove 1901 is provided on the top of the output shaft 19. In order to transmit the power of the output shaft 19 to the material tray 2, that is, to drive the material tray 2 to rotate by the output shaft 19, a groove 203 can be provided on the material tray 2, and the groove 203 is used to place a connecting plate. As shown in FIG3 , a spline shaft connected to the spline groove 1901 is fixed on the connecting plate. The spline shaft is aligned with the spline groove 1901, and then the connecting plate is inserted into the groove 203. The edge of the connecting plate is connected to the bolt hole on the groove 203 by bolts to fix the connecting plate, thereby transmitting power to the material tray 2 through the spline shaft and the connecting plate.

More specifically, the elastic positioning assembly includes a fixed cylinder 22, as shown in Figures 3 and 4, a guide groove is provided at one end of the fixed cylinder 22, a telescopic cylinder 24 is slidably inserted in the guide groove, and a spring 26 is provided in the guide groove to abut against the inner end of the telescopic cylinder 24, a mounting groove is provided at the outer end of the telescopic cylinder 24, an automatic telescopic rod 17 is installed in the mounting groove, a positioning block 25 is connected to one end of the automatic telescopic rod 17, the positioning block 25 has a head 2501 and a guide portion 2502, the guide portion 2502 is slidably connected to the inner wall of the mounting groove, the telescopic cylinder 24 has a slope 2401 at the notch of the mounting groove, and the notch of the positioning groove 202 is set to a reverse slope 2021 that matches the notch of the mounting groove.

Furthermore, the automatic telescopic rod 17 of the elastic positioning assembly does not work during the rotation of the material tray 2. At this time, the slope 2401 of the telescopic cylinder 24 in the elastic positioning assembly at the notch of the installation groove is coordinated with the reverse slope 2021 of the positioning groove 202 on the material tray 2 so that the material tray 2 can stop at the specified position. At this time, the automatic telescopic rod 17 is started, and the guide block connected to one end of the automatic telescopic rod 17 continues to extend into the positioning groove 202 after the automatic telescopic rod 17 is extended, thereby achieving a secondary positioning effect, ensuring that the material tray 2 can complete the corresponding operation at the specified position, and improving the reliability of the equipment through the positioning device. In this embodiment, an alarm can be provided. If the automatic telescopic rod 17 cannot extend the guide block into the positioning groove 202 after the automatic telescopic rod 17 is extended, it means that the material tray 2 has not stopped in place or the elastic positioning assembly has shifted and caused a fault. At this time, the alarm can promptly remind the staff.

Example 2

The difference between this embodiment and embodiment 1 is that a safety component is further provided on the positioning device, as shown in Figure 6, the safety component includes a limit cylinder 27 installed on the side of the support seat 16, the axial extension end of the limit cylinder 27 faces upward and the axial extension end is connected to a limit rod 28, and a limit groove is provided on the material tray 2 to cooperate with one end of the limit rod 28. When the limit rod 28 is connected to the limit groove, the loading device, the stamping device and the unloading device can all cooperate with the corresponding mold base 201 at the same time.

Furthermore, the safety component on the positioning device can lock the position of the material tray 2, which is further used to ensure the reliable progress of the stamping work. Since the safety component is rigidly connected by the limit rod 28 and the limit groove, it has a certain strength and can withstand a certain bending torque to avoid simultaneous damage to the loading device, stamping device and unloading device when the rotary motor 7 is mistakenly started. In order to protect the rotary motor 7 in this case, the rotating part of the rotary motor 7 can adopt a self-slip structure.

Secondly, the workpiece 8 is pressed on the die base 201 by the axial extension end of the clamping cylinder 4, and then the stamping cylinder 5 is started to drive the punching rod 6 to move. The punching rod 6 completes the stamping or punching work of the workpiece 8 from the bottom of the die base 201 by cooperating with the punching hole on the die base 201. After the stamping or punching work is completed, the punching rod 6 retreats first, and then the axial extension end of the clamping cylinder 4 retreats, and the material tray 2 rotates to the next process.
