Some flat iron parts are designed with threaded holes according to process requirements. At this time, CNC machine tools and other equipment are required to perform drilling processing on them.

[0004] When the threaded holes on the flat iron have a small diameter, a large number and are densely distributed, the traditional process uses a CNC machine tool to process the single holes in sequence. Due to the small diameter and large number of holes, tapping is required, and the diameter of the light hole and the spacing of the threaded holes are required to be high. The traditional single-hole processing is inefficient and the processing cost is high, which will affect the market competitiveness of the product. Therefore, the existing technology mostly adopts a multi-hole one-time processing solution for this situation, and when punching, it is necessary to use a corresponding device to fix and clamp the workpiece to ensure the punching accuracy and stability. However, the existing punching device has many requirements for the loading and unloading operations of the workpiece, and the loading and unloading process is complicated and slow, which greatly affects the efficiency of workpiece punching.

[0005] Therefore, it is urgent to design a punching device to meet the needs of punching multiple holes at one time and ensure the position accuracy between the holes. Utility Model Content

[0006] The problem to be solved by the utility model is to provide a precision punching device for a new energy storage sheet metal module.

DETAILED DESCRIPTION

[0023] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] like Figure 1 As shown, a precision punching device for a new energy storage sheet metal module includes a base plate 1, on which a positioning fixture 2 for fixing a workpiece is provided, one side of the positioning fixture 2 is provided with a lifting component 4 for ejecting the workpiece out of the positioning fixture 2, and the other side of the positioning fixture 2 is provided with a guide hole plate 3, and the guide hole plate 3 is provided with a plurality of guide holes 31 corresponding to the positions of the workpiece.

[0025] Specifically, the lifting component 4 and the positioning fixture 2 are first fixedly installed on the base plate 1 in sequence, so that the lifting component 4 is located below the positioning fixture 2, and then the guide plate 3 is set above the positioning fixture 2 to complete the assembly of the device, and then the workpiece is placed in the positioning fixture 2 to complete the fixed clamping, and then the corresponding multi-axis device (commonly known as a multi-hole drill, a multi-axis drill, a multi-axis machine tool or a multi-axis head, which is an existing hole processing equipment) is started. The device has multiple drill bits, and each drill bit can pass through the corresponding guide hole 31. As the drill bit moves downward, multiple corresponding hole positions are opened on the workpiece at one time; after the drilling is completed, the lifting component 4 is started to eject the processed workpiece from the positioning fixture 2 to facilitate the installation of the next workpiece to be processed; through this device, the operational difficulty and requirements of workpiece loading and unloading can be reduced, while ensuring the position accuracy of each hole position, the efficiency of drilling is greatly improved.

[0026] As mentioned above, the guide hole plate 3 has a plurality of guide holes 31, and the positions of the plurality of guide holes 31 correspond to the hole positions to be processed in the workpiece. Since the hole positions of the workpieces in the same batch are the same, processing of different hole positions can be achieved by simply replacing different guide hole plates 3, thereby ensuring that the device has wide applicability.

[0027] like Figure 2-3 As shown, the positioning fixture 2 includes a support plate 21 parallel to the guide hole plate 3, the support plate 21 is fixedly mounted on the base plate 1 through a support rod 23, and a positioning groove 22 for placing the workpiece is opened on the side of the support plate 21 close to the guide hole plate 3, and an elastic pin assembly 5 for fixing the workpiece is arranged on the side of the positioning groove 22.

[0028] As mentioned above, four support rods 23 are usually provided, in groups of two, symmetrically distributed at the edge of the bottom of the support plate 21, and the support rods 23 are fixedly connected to the support plate 21; when the positioning fixture 2 is fixedly installed, a screw can be driven from the side of the base plate 1 opposite to the positioning fixture 2, so that one end of the screw can pass through the base plate 1 and be screwed into the support rod 23, thereby completing the fixed installation of the positioning fixture 2 on the base plate 1.

[0029] After the workpiece is placed in the positioning groove 22, the elastic pin assembly 5 will automatically position and clamp the workpiece, thereby ensuring the clamping stability of the workpiece on the positioning fixture 2 and facilitating the one-time processing of multiple holes.

[0030] Furthermore, the elastic pin assembly 5 includes a positioning hole 51 formed on the side of the positioning groove 22, and a positioning pin 52 is movably inserted into the positioning hole 51, and one end of the positioning pin 52 can extend out of the positioning hole 51 and abut against the side end of the workpiece. After the workpiece is inserted into the positioning groove 22, the side of the workpiece will squeeze the positioning pin 52 to shrink, generating a pre-tightening force on the positioning pin 52, and the pre-tightening force will react on the side of the workpiece, thereby realizing automatic positioning and clamping of the workpiece, and preventing the workpiece from moving in a plane parallel to itself during the drilling process.

[0031] Specifically, a boss is provided in the positioning hole 51, and the positioning pin 52 includes a guide portion 522 and a positioning portion 521 that are integrally formed and connected. The diameter of the positioning portion 521 is larger than the diameter of the guide portion 522, and a spring 53 is sleeved on the outer side of the guide portion 522, and both ends of the spring 53 are respectively abutted against the boss and the positioning portion 521.

[0032] When the workpiece is embedded in the positioning groove 22, the positioning pin 52 will be squeezed into the positioning hole 51 first. With the support of the boss and the positioning portion 521, the spring 53 mounted on the guide portion 522 is compressed and stores a certain amount of elastic potential energy. When the workpiece is completely embedded in the positioning groove 22, the elastic force of the spring 53 pushes the positioning portion 521 to move closer to the workpiece, and finally it is tightly attached to the side of the workpiece to complete the fixed clamping of the workpiece; if the device is placed vertically, then under the joint action of the elastic pin assembly 5 and the positioning groove 22, the freedom of the workpiece in the horizontal plane is completely restricted; when the processing is completed, the workpiece can be ejected out of the positioning groove 22 by the lifting assembly 4, which is convenient for the disassembly of the workpiece.

[0033] There are three elastic pin assemblies 5 , which are distributed on two adjacent side surfaces of the positioning groove 22 , and two are symmetrically arranged on one side surface, and one is arranged at the middle position of the other side surface.

[0034] In addition, a fixing pin is radially penetrated at one end of the guide portion 522 opposite to the positioning portion 521, and the length of the fixing pin is greater than the inner diameter of the boss; this structure can prevent the positioning pin 52 from accidentally falling off from the positioning hole 51; when installing the elastic pin assembly 5, firstly, the spring 53 is sleeved on the outside of the guide portion 522, and then the positioning pin 52 sleeved with the spring 53 is placed into the positioning hole 51 from one side of the positioning groove 22, and the positioning portion 521 is squeezed in the longitudinal direction to compress the spring 53, and at the same time, the end of the guide portion 522 passes through the other side along the positioning hole 51 to the outside of the support plate 21, and the fixing pin is radially inserted into the pin hole of the guide portion 522 near the end, and the positioning portion 521 is loosened to complete the installation of the elastic pin assembly 5 on the support plate 21.

[0035] like Figure 1-2 As shown, the lifting assembly 4 includes a lifting hole 41 and a telescopic component 42 corresponding to the number and position of the lifting holes 41. The lifting holes 41 are opened at the bottom of the positioning groove 22 and pass through the support plate 21. The telescopic component 42 is fixedly installed on the base plate 1, and the output end of the telescopic component 42 can pass through the lifting hole 41 to the positioning groove 22.

[0036] The telescopic component 42 preferably adopts a cylinder. When the workpiece is drilled, the cylinder is started so that the telescopic end of the cylinder passes through the lifting hole 41 into the positioning groove 22, and the workpiece is ejected from the positioning groove 22, thereby completing the automatic disassembly of the workpiece.

[0037] Among them, there are two lifting holes 41 and two telescopic parts 42 arranged relatively to each other. The two lifting components 4 work together to not only increase the lifting force, but also ensure that the workpiece is smoothly separated from the positioning groove 22, avoiding tilting or jamming caused by unbalanced force.

[0038] like Figure 1 , Figure 4 As shown, a guide rod 6 perpendicular to the guide hole plate 3 is fixedly mounted on the bottom plate 1, a mounting hole 32 is opened near the edge of the guide hole plate 3, and the guide rod 6 is inserted into the mounting hole 32. Under the mutual cooperation between the guide rod 6 and the mounting hole 32, the guide hole plate 3 can move along the axial direction of the guide rod 6, and the guide hole plate 3 can also be fixed on the guide rod 6 by screws.

[0039] There are two guide rods 6 and two mounting holes 32 to ensure that the guide hole plate 3 remains parallel to the support plate 21 and the bottom plate 1 during the movement.

[0040] As mentioned above, a flange seat 7 corresponding to the position and number of the guide rods 6 is fixedly mounted on the bottom plate 1 , and one end of the guide rod 6 is fixedly embedded in the flange seat 7 .

[0041] The flange seat 7 has a flange hole inside, which can be used for the guide rod 6 to be inserted, and the flange seat 7 is fixedly connected to the base plate 1 by bolts. After one end of the guide rod 6 is inserted into the flange hole, the guide rod 6 can be fixed in the flange hole radially by screws; through this structure, the installation of the guide rod 6 can be facilitated and its position accuracy can be guaranteed.

[0042] In addition, the ear portion of the multi-axis device is also mounted on the guide rod 6 and can move along the axial direction of the guide rod 6. Therefore, the guide rod 6 can also play a guiding role.

[0043] Working principle:

[0044] The device is composed of a base plate 1, a positioning fixture 2, a guide hole plate 3, a lifting assembly 4, an elastic pin assembly 5, a guide rod 6 and a flange seat 7. The device can reduce processing costs, increase processing efficiency and ensure the precision of hole spacing dimensions.

[0045] Before drilling, complete the assembly of the device. First, fix the jacking component 4 and the positioning fixture 2 on the base plate 1 in sequence, so that the jacking component 4 is located below the positioning fixture 2, and then set the guide plate 3 above the positioning fixture 2. Then install the elastic pin assembly 5 on the positioning fixture 2, and finally fix the ear of the multi-axis device. After the assembly is completed, place the workpiece into the positioning groove 22 of the positioning fixture 2, start the multi-axis device for automatic drilling, and start the jacking component 4 after the drilling is completed, and use its telescopic component 42 to eject the workpiece from the fixture.

[0046] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without deviating from the technical concept of the utility model.
