DETAILED DESCRIPTION
[0025] The following is combined with Figure 1-4 This application is described in further detail.
[0026] The present application embodiment discloses a punching machine capable of continuous punching. Figure 1 and Figure 2 The punching machine capable of continuous punching includes a workbench 1, a mounting beam 2, a punching plate 3, a drill bit 4, a rotary drive device 5, a linear drive device 6, a clamping and positioning device 7, and a position adjustment device 8. Among them, the mounting beam 2 is fixedly connected to the workbench 1, and the punching plate 3 is vertically slidably connected to the mounting beam 2. The drill bit 4 is rotatably connected to the punching plate 3 and is used to punch the workpiece. The workbench 1 is provided with a punching hole 11 for the drill bit 4 to pass through. The rotary drive device 5 is fixedly connected to the punching plate 3 and is used to drive the drill bit 4 to rotate. The linear drive device 6 is installed on the mounting beam 2 and is used to drive the punching plate 3 to slide vertically, thereby realizing the punching operation on the workpiece. The position adjustment device 8 is installed on the workbench 1 and is used to automatically adjust the position of the workpiece, thereby realizing continuous drilling 921.
[0027] Reference Figure 1 and Figure 2 The rotary drive device 5 can be a rotary motor 51, and the drill bit 4 is fixedly connected to the output shaft of the rotary motor 51, so that the drill bit 4 is driven to rotate by the rotary motor 51. The linear drive device 6 includes a driving motor 61 fixedly connected to the mounting beam 2 and a screw rod 62 fixedly connected to the output shaft of the driving motor 61. The stamping plate 3 is threadedly connected to the screw rod 62, and a sliding groove 21 is provided on the mounting beam 2 for one end of the stamping plate 3 to be embedded to limit the vertical sliding of the stamping plate 3. By driving the screw rod 62 to rotate by the driving motor 61, the stamping plate 3 can be driven to slide in the sliding groove 21, so as to drive the stamping plate 3 to rise and fall.
[0028] The screw rod 62 can be a reciprocating screw rod, and a driving ball (not shown in the figure) that matches the thread groove of the reciprocating screw rod is fixedly connected to the stamping plate 3. When the screw rod 62 rotates, the driving ball can be driven to slide in the thread groove of the reciprocating screw rod, thereby driving the stamping plate 3 to move up and down. By driving the motor 61 to start, the drill bit 4 can be automatically driven to move up and down to achieve continuous drilling 921.
[0029] Reference Figure 3 The clamping and positioning device 7 is installed on the workbench 1 and is used to clamp the workpiece. The clamping and positioning device 7 includes a first clamping assembly 71 and a second clamping assembly 72 that are arranged opposite to each other, and a working space for the workpiece to be embedded is formed between the first clamping assembly 71 and the second clamping assembly 72. In the present application, the first clamping assembly 71 and the second clamping assembly 72 have the same structure, and the present application takes the specific structure of the first clamping assembly 71 as an example for explanation.
[0030] Specifically, the first clamping assembly 71 includes a fixed plate 711 fixed on the workbench 1 and an abutment plate 712 slidably connected to one side of the fixed plate 711. The abutment plate 712 is located on the side of the fixed plate 711 facing the second clamping assembly 72. An abutment member 713 is provided between the abutment plate 712 and the fixed plate 711, which is used to push the abutment plate 712 to slide to the side away from the fixed plate 711, thereby clamping the workpiece. The position adjustment device 8 is located at one end of the working space, and is used to drive the workpiece to slide in the working space, so that each position of the workpiece slides to the bottom of the drill bit 4 in turn to drill a hole 921 through the drill bit 4, thereby realizing continuous punching. The position adjustment device 8 includes a cylinder 81 fixed on the workbench 1 and a push plate 82 fixed on the piston rod of the cylinder 81. The cylinder 81 is configured to stop after moving a set distance to ensure the accuracy of the punching position each time.
[0031] In order to further improve the clamping accuracy and stability, the abutment member 713 adopts an abutment spring and a guide member 714 is added. The guide member 714 includes a mounting tube 7141 fixedly connected to the fixed plate 711 and a sliding rod 7142 slidably connected in the mounting tube 7141. One end of the sliding rod 7142 away from the mounting tube 7141 is fixedly connected to the abutment plate 712, which is used to guide the sliding of the abutment plate 712. The abutment plate 712 is always in contact with the workpiece under the elastic action of the abutment spring, ensuring the clamping firmness of the workpiece. At the same time, the design of the guide member 714 also ensures the stability and accuracy of the abutment plate 712 during the sliding process, thereby further improving the clamping effect on the workpiece.
[0032] Reference Figure 3 and Figure 4 A fixing member is also provided between the mounting cylinder 7141 and the sliding rod 7142 for fixing the relative positions of the mounting cylinder 7141 and the sliding rod 7142 .
[0033] The fixing member includes a fixing cylinder 715 which is sleeved on the sliding rod 7142 and slidably matched with the sliding rod 7142. Specifically, a plurality of notches 7143 are provided at one end of the mounting cylinder 7141 facing the sliding rod 7142, and a plurality of notches 7143 are provided at intervals around the axis of the mounting cylinder 7141, and an elastic pressing piece 7144 is formed between the plurality of notches 7143. The outer surface of the mounting cylinder 7141 is processed with an external thread, and the external thread is processed on the side of the notch 7143 away from the sliding rod 7142. The fixing cylinder 715 includes a fixing section 7151 for matching with the external thread on the mounting cylinder 7141 and a holding section 7152 for matching with the elastic pressing piece 7144, and the inner hole diameter of the holding section 7152 gradually decreases from one end close to the fixing section 7151 to one end away from the fixing section 7151. When the fixing section 7151 is screwed onto the external thread of the installation cylinder 7141, the elastic pressing piece 7144 is also located in the holding section 7152. Due to the variable diameter setting of the inner hole of the holding section 7152, the force of the elastic pressing piece 7144 pressing on the sliding rod 7142 can be adjusted by rotating the fixing cylinder 715, thereby adjusting the tightness between the fixing cylinder 715 and the sliding rod 7142, and then achieving the fixation between the fixing cylinder 715 and the sliding rod 7142. When in use, the fixing member can guide the sliding of the abutment plate 712 on the one hand to ensure the sliding of the abutment plate 712; on the other hand, when the abutment plate 712 abuts against the workpiece to clamp the workpiece through the two abutment plates 712, the relative position of the fixing cylinder 715 and the sliding rod 7142 can also be fixed by screwing the fixing cylinder 715, so as to avoid the abutment plate 712 being pushed to move when the workpiece is subjected to force, thereby affecting the placement accuracy of the workpiece.
[0034] At the same time, in order to more accurately control the position adjustment distance of the workpiece during the continuous punching process and realize the precise adjustment of the workpiece position, a linear displacement sensor 83 is also provided on the cylinder 81, the main body of the linear displacement sensor 83 is fixedly connected to the cylinder body of the cylinder 81, and the sliding piece of the linear displacement sensor 83 is fixedly connected to the piston rod of the cylinder 81, so that the moving distance of the piston rod of the cylinder 81 can be detected by the linear displacement sensor 83.
[0035] Among them, the linear displacement sensor 83 and the cylinder 81 are both connected to the controller, and the controller can be a PLC controller. When the cylinder 81 starts to drive the piston rod to extend and retract, the linear displacement sensor 83 will detect the extension and retraction of the piston rod of the cylinder 81, and transmit the detection data to the PLC controller in real time. When the detection data received by the PLC controller from the linear displacement sensor 83 reaches the set value, the cylinder 81 will be controlled to stop, so as to push the workpiece to the set distance. While realizing automatic adjustment of the workpiece position, the accuracy and efficiency of continuous punching are also guaranteed.
[0036] Reference Figure 1 and Figure 2An auxiliary fixing device 9 for pressing and fixing the workpiece around the hole 921 to be drilled is also provided on the stamping plate 3. When the drill bit 4 drills the workpiece 921, the auxiliary fixing device 9 can fix the workpiece around the drilling hole 921 position, thereby reducing the probability of vibration or deviation of the workpiece during the drilling process 921 and ensuring the quality of the drilling 921.
[0037] The auxiliary fixing device 9 includes a connecting member 91 fixedly connected to the side of the punching plate 3 facing the workbench 1 and a limiting plate 92 fixedly connected to the side of the connecting member 91 away from the punching plate 3. The limiting plate 92 is provided with a drilling hole 921 for the drill bit 4 to pass through. Among them, the connecting member 91 includes an auxiliary spring 911 and a telescopic rod 912 fixedly connected between the punching plate 3 and the limiting plate 92. Under normal conditions, the limiting plate 92 is located below the drill bit 4 under the elastic force of the auxiliary spring 911. When the punching plate 3 descends and drives the drill bit 4 to approach the workpiece, the limiting plate 92 will first abut against the workpiece. As the punching plate 3 continues to descend, the telescopic rod 912 contracts, the auxiliary spring 911 is compressed, and the drill bit 4 passes through the drilling hole 921 to drill the workpiece 921. In the process of drilling the hole 921, the workpiece can be pressed and held by the limiting plate 92 to ensure the accuracy of the drilling hole 921.
[0038] The implementation principle of a punching machine capable of continuous punching in the embodiment of the present application is as follows: when in use, the workpiece is placed in the working space between the first clamping assembly 71 and the second clamping assembly 72. The abutment plate 712 is pushed to slide by the abutment member 713, so that the workpiece is clamped by the two abutment plates 712. Then, the rotary drive device 5 and the linear drive device 6 are started to drive the drill bit 4 to rotate and move downward to punch the workpiece. During the punching process, the limit plate 92 presses and holds the surroundings of the workpiece drilling hole 921 to ensure the placement stability of the workpiece. After the punching is completed, the piston rod of the cylinder 81 drives the push plate 82 to move, and the elongation of the piston rod of the cylinder 81 is controlled by the linear displacement sensor 83, so that the workpiece slides a set distance in the working space. As the rotary motor 51 continues to rotate, the drill bit 4 is driven to move to the uppermost end and then automatically descends, thereby realizing the work of drilling 921 again on the workpiece, thereby completing the continuous drilling 921 work.
[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
