The control method of the secondary pusher mechanism 100 according to the present embodiment will be described in detail below with reference to fig. 2, 4, 6, and 8, and for convenience of description, the workpiece 500 before processing is referred to as a workpiece 500 to be processed, and the workpiece 500 after processing is referred to as a processed workpiece 500.
Step one, after the workpiece 500 to be processed is processed into the processed workpiece 500 at the processing station of the machine tool, a control system (not shown) of the machine tool controls the primary pushing device 4 to cooperate with the primary sliding assembly 2, so as to push the processed workpiece 500 away from the processing station.
Taking the vertical broaching machine of this embodiment as an example, before the vertical broaching machine processes the workpiece 500 to be processed, the secondary pushing mechanism 100 is in the secondary pushing state (refer to fig. 6), firstly, an operator places the workpiece 500 to be processed on the positioning hole 61 of the pushing plate 6 at the loading and unloading station, and meanwhile, a tool lifting device (not shown) on the vertical broaching machine lifts the broach 800 (refer to fig. 1) upward, so that there is enough space for the workpiece 500 to be processed to be pulled to the processing station by the secondary pushing mechanism 100. It should be noted that, in the vertical broaching machine of this embodiment, a protection door (not shown) is further disposed at one end of the working platen 300 close to the loading and unloading station, so that the loading and unloading station is actually located outside the protection door, and an operator stands outside the protection door to directly complete loading and unloading operations on the loading and unloading station.
As shown in fig. 2, when the control system controls the movable end of the secondary pushing device 5 and the movable end of the primary pushing device 4 to sequentially retract to a proper position, that is, when the secondary pushing mechanism 100 retracts to the initial state before pushing, the circle center of the positioning hole 61, the circle center of the shaft hole of the workpiece 500 to be processed, and the circle center of the broach hole 310 are aligned, the proximity switch located at the last side detects the sensing bracket and transmits a retraction signal to the control system, and the control system starts to execute a control instruction for processing the workpiece after receiving the retraction signal. First, the broaching tool 800 is moved downward until the lower end of the broaching tool 800 is seated in the broaching tool hole 310. It should be noted that, two ends of the broach 800 each have a polished rod section without cutter teeth, and a cutter teeth section with cutter teeth is arranged between the polished rods at the two ends, when the lower end of the broach 800 is fixed in the broach hole 310, actually the polished rod section at the lower end of the broach 800 extends into the axial hole of the workpiece 500 and is fixed in the broach hole 310, and the lowest end of the cutter teeth section is located above the upper end face of the workpiece 500 to be processed. Then, the broaching tool 800 is kept still, and the work table plate 300 moves upward in the vertical direction, so that the workpiece 500 to be processed placed in the positioning hole 61 is driven to move upward together, and the tool tooth section of the broaching tool 800 processes the shaft hole of the workpiece 500 to be processed. In the whole process, the chip brushing disc 600 is positioned at the rear side of the processing station, and the secondary pushing mechanism 100 is kept in the initial state. When the work table 300 is moved upward until the broaching tool 800 is completely disengaged from the broaching hole 310, the work 500 to be machined is finished.
As shown in fig. 4, after the workpiece 500 to be processed is processed, the control system controls the movable end of the first-stage pushing device 4 to extend forward, so as to push the material pushing plate 6 away from the processing station, when the movable end of the first-stage pushing device 4 extends to a proper position, the center of the shaft hole of the chip brushing disc 600 and the center of the chip brushing hole 320 are aligned with the center of the broach hole 310, the proximity switch located in the middle detects the induction bracket, and transmits a chip brushing signal to the control system, and the control system starts to execute a chip brushing control instruction after receiving the chip brushing signal. In the chip brushing process, the control system controls the working table plate 300 to move downwards along the vertical direction, in the moving process, the shaft hole of the chip brushing disc 600 penetrates through the broach 800, and the bristles arranged in the shaft hole of the chip brushing disc 600 clean the residual iron chips and the like on the broach 800. When the platen 300 is moved down to the desired position, the platen 300 stops moving and the broach 800 is lifted upward and away from the brush plate 600.
And step two, the control system controls the secondary pushing device 5 to be matched with the secondary sliding component 3 and the primary sliding component 2 together, and pushes the processed workpiece 500 pushed away from the processing station to a feeding and discharging station of the machine tool for blanking.
As shown in fig. 5, after the broach 800 is lifted, the movable end of the secondary pushing device 5 extends forward, when the movable end of the secondary pushing device 5 extends to a proper position, the material pushing plate 6 is pushed to the upper and lower material positions, and meanwhile, the lifting mechanism 9 controls the material receiving frame 8 to turn upwards to receive the material pushing plate 6, at this time, the proximity switch located at the front side detects the induction bracket and transmits a feeding and discharging signal to the control system, and the control system starts to execute a feeding and discharging control instruction after receiving the feeding and discharging signal. It should be noted that the lifting mechanism 9 may first turn over the material receiving frame 8 upwards before the movable end of the secondary pushing device 5 is not yet extended, or may also turn over the material receiving frame 8 upwards when the movable end of the secondary pushing device 5 is extended and the material receiving frame 8 is about to reach the upper and lower material positions, as long as the material receiving frame 8 is ensured to receive the material pushing plate 6. After the material pushing plate 6 is pushed to the upper material level and the lower material level, an operator can take down a processed workpiece 500 placed on the material pushing plate 6 from the material pushing plate 6 and then replace with another workpiece 500 to be processed, then the control system controls the movable end of the secondary material pushing device 5 to retract backwards firstly, controls the movable end of the primary material pushing device 4 to retract backwards subsequently, and when the secondary material pushing mechanism 100 retracts to the initial state before material pushing, the material pushing plate 6 is pulled to a processing station by the secondary material pushing mechanism 100 again, and then a new round of workpiece processing is started.
The embodiment provides a control method for a secondary pushing mechanism of a machine tool, the pushing plate is pushed to a feeding and discharging station positioned on the outer side of a working table plate of the machine tool through the secondary pushing mechanism, an operator can complete feeding and discharging operations on the feeding and discharging station positioned on the outer side of the working table plate only by standing outside a protective door without stretching a handle into a processing station of a workpiece, so that the labor intensity of the operator is reduced, the damage to the operator caused by misoperation of the machine tool or residual scrap iron of the machine tool, cooling water and the like can be avoided, and the production efficiency is improved while the personal safety of the operator can be effectively protected.
