Description

Technical Field

[0001] The utility model relates to a charging pile gun cover processing device, belonging to the technical field of charging pile gun cover processing equipment. Background Art

[0002] The charging pile gun housing is generally a long waist-shaped deep countersunk hole structure, and its shape and structure are as follows Figure 1 As shown in the figure, the current processing technology of charging pile gun cover is generally: first, the thin plate is bent through multiple passes, then assembled and welded into shape, and finally the welded parts are polished. The original electric gun cover processing process has many process steps, the production cycle of technicians is long, the welding workload is large, and the polishing requirements are high, resulting in the inability to effectively control the cost.

[0003] In order to reduce production costs, a stretching and stamping process is used to stamp and stretch the thin plate once to form the main body of the charging pile gun cover. At the same time, the punching, window opening and trimming operations are completed during the stamping operation, so that the production of the finished charging pile gun cover can be completed in one stamping. However, since the trimming operation of the new process requires the edge of the cover to be cut off as a whole after the stretching is completed, the requirements for the stretching and stamping die are high, the complexity of the die structure is greatly increased, and the corresponding production cost is high. For this reason, the trimming operation of the new process stretching die is partially cancelled, thereby simplifying the stretching die structure and reducing the die cost. Instead, the edge of the cover is milled on a milling machine after stretching to complete the trimming operation. Due to the use of milling processing technology, thin plate parts are very easy to deform. At present, in actual production, product quality is guaranteed by reducing the processing amount, which is time-consuming and labor-intensive, and the production efficiency is not high.

[0004] Therefore, there is an urgent need for a charging pile gun cover processing device with a simple structure, convenient cover fixing, convenient assembly and disassembly, and high production efficiency. Summary of the invention

[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a charging pile gun cover processing device with simple structure, convenient cover fixing, convenient assembly and disassembly, and high production efficiency.

[0006] The purpose of the utility model is achieved in this way:

[0007] A charging pile gun cover processing device comprises a base and a boss arranged on the base; a long waisted round deep countersunk hole for accommodating the charging pile gun cover is provided at the center of the boss, and a pressing block for pressing and fixing the charging pile gun cover is installed in the long waisted round deep countersunk hole; the pressing block is embedded in the inner cavity of the charging pile gun cover and contacts with the inner surface pressing surface of the bottom shell of the charging pile gun cover.

[0008] Furthermore, a positioning column for positioning the charging pile gun cover is provided on the inner side wall of the long waisted circular deep countersunk hole.

[0009] Furthermore, a threaded countersunk hole is provided at the bottom of the long waisted round deep countersunk hole of the base; a through hole is provided on the pressure block; a fixing bolt is embedded in the through hole; the pressure block is screwed and installed in the threaded countersunk hole by the fixing bolt and is fixed in the long waisted round deep countersunk hole.

[0010] Furthermore, the pressing block is provided with a lifting ring for easy installation and disassembly.

[0011] Furthermore, there are two lifting rings, both of which are arranged in the countersunk holes on the top surface of the pressing block.

[0012] Furthermore, the edge of the base is provided with a plurality of U-shaped grooves for easy installation and positioning.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model has a simple overall structure. The charging pile gun cover is fixedly clamped between the boss and the pressing block, and the pressed block and the boss are fixed in an internal and external wrapped manner, and only the edge to be processed is exposed. Even with a large milling feed rate, the deformation of the main thin plate of the charging pile gun cover will not be caused. An ordinary milling machine can process the edge of the charging pile gun cover in one cut. The processing is fast, efficient and without deformation, and the disassembly and assembly are convenient and fast, which greatly improves the quality and efficiency of the edge processing of the charging pile gun cover.

[0021] See also Figures 2~4 The utility model relates to a charging pile gun cover processing device, comprising a base 1, a boss 2 arranged on the base 1; the edge of the base 1 is provided with a plurality of U-shaped grooves 9 for easy installation and positioning; the U-shaped grooves 9 are arranged on the base 1 for easy installation on the upper limit position of the milling machine workbench;

[0022] The center of the boss 2 is provided with a long waist round deep countersunk hole for accommodating the charging pile gun housing 3, and a pressing block 4 for pressing and fixing the charging pile gun housing 3 is installed in the long waist round deep countersunk hole;

[0023] The inner side wall of the long waisted circular deep countersunk hole is provided with a positioning column 5 for positioning the charging pile gun cover 3, and the bottom of the long waisted circular deep countersunk hole is provided with a threaded countersunk hole for installing the fixing bolt 4 of the pressure block 4; the pressure block 4 is provided with a through hole, and the fixing bolt 6 is embedded in the through hole, and the pressure block 4 is screwed and installed in the threaded countersunk hole at the bottom of the long waisted circular deep countersunk hole and fixed in the long waisted circular deep countersunk hole; the pressure block 4 is embedded in the inner cavity of the charging pile gun cover 3 and contacts the inner surface compression surface of the bottom shell of the charging pile gun cover 3; because a window is opened on the bottom shell of the charging pile gun cover 3, the fixing bolt 6 is screwed and installed on the boss 2 through the window; the positioning column 5 limits the outer side wall of the long waist of the charging pile gun cover 3, and then the charging pile gun cover 3 is pressed tightly into the boss 2 by the pressure block 4, exposing a circle of edge parts to be processed;

[0024] In order to facilitate the installation and disassembly of the overall device or a separate pressing block 4, two countersunk holes 8 are provided on the top surface of the pressing block 4, and a lifting ring 7 is provided in each countersunk hole 8; in order not to affect the milling operation, the top heights of the fixing bolts 6 and the lifting rings 7 are not higher than the top surface of the pressing block 4, and the top surface of the pressing block 4 is not higher than the top surface of the boss 2.

[0025] During assembly, first use the U-shaped groove 9 to fix the base 1 on the workbench of the milling machine; remove the pressure block 4 from the boss 2, and place the charging pile gun cover 3 in the long waisted deep countersunk hole of the boss 2, exposing only a circle of the edge of the charging pile gun cover 3; then place the boss 2 in the inner cavity of the charging pile gun cover 3, and use the fixing bolt 6 to pass through the bottom shell window of the charging pile gun cover 3 and threadedly fix it with the boss 2 to complete the workpiece clamping; start the milling machine, and mill a circle of the edge of the charging pile gun cover 3 to complete the edge processing of the charging pile gun cover 3; when disassembling, you only need to reverse the above assembly process to remove the charging pile gun cover 3. Through the milling processing device of the utility model, since the charging pile gun cover 3 is clamped and fixed by the boss 2 and the pressure block 4 in an internal and external wrapped manner, even a large milling feed amount will not cause deformation of the main thin plate of the charging pile gun cover 3, and it can meet the needs of an ordinary milling machine to process the edge of the charging pile gun cover 3 in one cut, and the processing is fast, efficient and deformation-free, which greatly improves the quality and efficiency of the edge processing of the charging pile gun cover.
