[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0021] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them.

[0023] In the related art, a fixed electric cylinder is used to drive a fixed plate to fix the workpiece. However, when fixing the workpiece, the fixed electric cylinder needs to be controlled manually or by program to work. It is not possible to automatically clamp the workpiece when the punching mechanism descends to punch holes, and an additional driving source is required to clamp the workpiece, which is more troublesome.

[0024] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a punching device for mechanical processing, by arranging lower pressure plates on both sides of the punching frame, and arranging a hydraulic drive component under the lower pressure plate, one end of the hydraulic drive component is connected to the hydraulic clamping component, when descending to drill, the punching frame drives the lower pressure plate to descend, so that the lower pressure plate drives the hydraulic drive component to work, and the hydraulic drive component drives the hydraulic clamping component to work, so that the hydraulic clamping component automatically clamps the workpiece, and when the drilling is completed and the workpiece is raised, it can automatically release the workpiece, so that the workpiece can be automatically clamped and released when drilling, and no additional driving components are required to drive the clamping mechanism. Because the deeper the drilling depth, the greater the pressure of the lower pressure plate on the hydraulic drive component, and then the pressure applied by the hydraulic drive component to the hydraulic clamping component is also greater, so that the clamping force of the workpiece is increased, and insufficient pressure on the workpiece is avoided, which causes the workpiece to shake when drilling, thereby improving the quality of drilling.

[0025] The present application is described below with reference to the accompanying drawings and specific embodiments: Combination Figure 1-Figure 5The embodiment of the present application provides a punching device for mechanical processing, including a machine body 10, a punching assembly 20 is installed at the front end of the machine body 10, and the punching assembly 20 includes: a transverse moving frame 21, fixedly connected to the front end of the machine body 10; a transverse screw 22, rotatably connected to the inside of the transverse moving frame 21; a transverse motor 23, installed on one side of the machine body 10, and the output shaft is connected to one end of the transverse screw 22; a transverse slide 24, slidably connected to the front surface of the transverse moving frame 21, and the back is threadedly connected to the outer wall of the transverse screw 22; a punching hydraulic cylinder 25, installed on the top of the transverse slide 24; a punching frame 26, slidably connected to the front surface of the transverse slide 24, and the top is connected to the telescopic end of the punching hydraulic cylinder 25; a punching motor 27, fixedly connected to the front end of the punching frame 26; a drill bit 28, fixedly connected to the output shaft of the punching motor 27; When drilling, the traverse motor 23 is started to drive the traverse screw 22 to rotate, so that the traverse screw 22 drives the traverse slide 24 to move horizontally through the screw nut behind the traverse slide 24 to adjust the lateral position of the drilling. After the lateral position is adjusted, the drilling frame 26 is driven down by the drilling hydraulic cylinder 25, so that the drilling frame 26 drives the drill bit 28 at the lower end of the drilling motor 27 to descend, so that the drill bit 28 contacts the workpiece on the drilling table of the machine body 10 to perform the drilling operation. The outer side wall of the punching frame 26 is symmetrically provided with a lower pressing plate 30; There are two lower pressing plates 30, which are directly fixed on both sides of the punching frame 26. When the punching frame 26 descends, the lower pressing plates 30 can be driven to descend. A hydraulic drive assembly 40 is symmetrically arranged on the punching table of the machine body 10, and the hydraulic drive assembly 40 includes: a hydraulic box 41; a hydraulic flow channel 42, which is opened inside the hydraulic box 41; a hydraulic drive cylinder 43, which is arranged on the top of the hydraulic box 41, and the bottom inlet and outlet liquid ends are connected to the hydraulic flow channel 42, and hydraulic oil is arranged inside; a driving piston 44, which is slidably connected to the inside of the hydraulic drive cylinder 43; a driving rod 45, which is fixedly connected to the top of the driving piston 44; a top plate 46, which is fixedly connected to the top of the driving rod 45; a return spring 47, which is arranged at the bottom of the top plate 46, and the bottom end is connected to the top of the hydraulic drive cylinder 43; When the lower pressing plate 30 descends, it contacts the top plate 46 and drives it to descend, so that the top plate 46 drives the driving piston 44 in the hydraulic driving cylinder 43 to descend through the driving rod 45, so that the driving piston 44 pumps the hydraulic oil in the hydraulic driving cylinder 43 into the hydraulic flow channel 42 in the hydraulic box 41, so that the hydraulic oil enters the hydraulic clamping assembly 50 and the linkage water spray assembly 60 respectively through the hydraulic flow channel 42. After the drilling is completed, the lower pressing plate 30 rises and does not contact the top plate 46. At this time, the top plate 46 is driven to rise and reset through the reset spring 47, so that the driving piston 44 rises and draws the hydraulic oil in the hydraulic flow channel 42 back into the hydraulic driving cylinder 43; A hydraulic clamping assembly 50 is provided on one side of the hydraulic box 41, one end of which is connected to the hydraulic channel 42. The hydraulic clamping assembly 50 includes: a clamping hydraulic cylinder 51, which is arranged inside the hydraulic box 41, and one end of which is connected to the hydraulic channel 42; a clamping piston 52, which is slidably connected to the inside of the clamping hydraulic cylinder 51; a clamping rod 53, which is fixedly connected to one side of the clamping piston 52; a clamping spring 56, which is arranged at one end of the clamping rod 53; and a clamping head 57, which is arranged at one end of the clamping spring 56. The hydraulic oil enters the clamping hydraulic cylinder 51 through the hydraulic flow channel 42, so that the hydraulic oil drives the clamping piston 52 in the clamping hydraulic cylinder 51 to move to the left (see Figure 4 ), so that the clamping piston 52 drives the clamping head 57 on the clamping spring 56 to move to the left through the clamping rod 53, so that the clamping head 57 clamps the workpiece. When the clamping piston 52 continues to move to the left, the pressure applied by the clamping spring 56 to the clamping head 57 becomes greater, so that the mechanism can not only automatically clamp the workpiece, but also further enhance the clamping force of the workpiece and enhance the stability of the workpiece clamping as the drilling continues; A linkage water spray assembly 60 is provided on one side of the hydraulic box 41, one end of which is connected to the hydraulic flow channel 42. The linkage water spray assembly 60 includes: a water spray hydraulic cylinder 61, which is arranged inside the hydraulic box 41, and one end of which is connected to the hydraulic flow channel 42; a suction piston 62, which is slidably connected to the inside of the water spray hydraulic cylinder 61; a suction rod 63, which is fixedly connected to one side of the suction piston 62; a water spray piston 64, which is fixedly connected to one end of the suction rod 63; a water spray barrel 65, which is arranged on the punching table of the machine body 10, and the inner side wall is slidably connected to the water spray piston 64; a one-way water inlet valve 66, which is arranged at the liquid extraction end of the water spray barrel 65; a water storage tank 67, which is arranged at the bottom of the one-way water inlet valve 66; a water suction pipe 68, which is arranged inside the water storage tank 67, and the top end is connected to the liquid extraction end of the one-way water inlet valve 66; a one-way water spray valve 69, which is fixedly connected to the liquid spray end of the water spray barrel 65; The hydraulic oil enters the water spray hydraulic cylinder 61 through the hydraulic flow channel 42, so that the hydraulic oil drives the suction piston 62 in the water spray hydraulic cylinder 61 to move to the left (see Figure 5 ), the suction piston 62 drives the water spray piston 64 to move to the left in the water spray cylinder 65 through the suction rod 63, so that the water spray piston 64 pushes the water in the water spray cylinder 65 to be sprayed out from the one-way water spray valve 69, so that the one-way water spray valve 69 sprays water to cool the workpiece. When resetting, the hydraulic oil flows out of the water spray hydraulic cylinder 61, so that the suction piston 62 in the water spray hydraulic cylinder 61 drives the water spray piston 64 on the suction rod 63 to move to the right and reset (see Figure 5 ), so that the water spray piston 64 draws the water in the water storage tank 67 into the water spray cylinder 65 through the one-way water inlet valve 66 and the water suction pipe 68, thereby completing the reciprocating water spraying operation.

By setting the guide plate 54 and the guide rod 55, the guide plate 54 and the guide rod 55 limit the clamping head 57 so that the clamping head 57 will not shake during clamping.

[0030] In some embodiments, a sealing ring is provided at the connection between the water spray hydraulic cylinder 61 and the suction rod 63. By providing the sealing ring, the sealing performance inside the cylinder is improved.
