DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0018] The embodiment of the present application provides a down-pressing device for electric box cover, which is mainly used for accurately pressing the T sleeve 8 into the hole position of the electric box cover 7. The down-pressing device comprises a down-pressing mechanism and a T sleeve positioning tool for electric box cover, and the down-pressing mechanism comprises a bracket, a pressing block and a hydraulic cylinder fixedly installed on the bracket for driving the pressing block to move up and down.

[0019] Reference Figures 1 to 3The pressing T sleeve positioning tool of the electric box cover comprises a lower base 1, an intermediate base 2, a connecting column 3, a positioning pin 4 and a spring 5. The connecting column 3 is internally provided with a cavity 31, and the top of the column is provided with a through hole 32 vertically communicating with the cavity 31. The positioning pin 4 is vertically movably connected in the through hole 32. The intermediate base 2 is fixedly installed at the bottom of the connecting column 3, thereby closing the bottom of the cavity 31. The lower end of the positioning pin 4 is provided with an annular flange 41 with an outer diameter larger than the inner diameter of the through hole 32, for limiting the positioning pin 4 from being pulled out of the through hole 32 upwardly. The spring 5 is installed in the cavity 31 and abuts against the positioning pin 4 and the intermediate base 2 at two ends respectively, for providing a reverse reset force, so that the upper part of the positioning pin 4 is exposed out of the through hole 32 in an initial state. The top of the connecting column 3 is provided with a product positioning surface 33 for supporting a product. The upper part of the positioning pin 4 is further provided with a product positioning part 42 for positioning a product hole. The positioning pin 4 is further provided with an insert positioning step part 43 above the product positioning part 42, for positioning a T sleeve 8. The insert positioning step part 43 is coaxially arranged with the product positioning part 42, and the outer diameter of the product positioning part 42 is larger than that of the insert positioning step part 43. When the positioning pin 4 is pressed downwardly, the positioning pin 4 can move downwardly with the T sleeve 8. The intermediate base 2 comprises an intermediate ring part 21 with a larger outer diameter, and a lower convex part 22 and an upper convex part 23 with smaller outer diameters respectively arranged at the upper part and the lower part of the intermediate ring part 21. The lower base 1 is provided with a recess 11 for accommodating the lower convex part 22. The intermediate ring part 21 is arranged on the lower base 1, and the lower convex part 22 is inserted into the recess 11. One or more than one threaded rod 6 is threadedly connected to the lower base 1, for tightly pressing the lower recess 11. The upper convex part 23 is inserted into the cavity 31 of the connecting column 3. The pressing block is arranged above the positioning pin 4.

[0020] The lower pressing device can accurately press the T sleeve 8 into the hole of the electric box cover 7, thereby improving the installation efficiency and quality of the T sleeve 8. The intermediate base 2 and the lower base 1 are detachable, so that when different sizes of T sleeves 8 need to be pressed, only the corresponding mechanism above the lower base 1 needs to be replaced, thereby reducing the changeover time.

[0021] The upper convex part 23 and the connecting column 3 are fastened by threads or locked by screws.

[0022] The outer end of the threaded rod 6 is further provided with a circular handle 61. The circular handle 61 facilitates the use of the threaded rod 6 for disassembling the intermediate base 2.

[0023] The upper surface of the upper convex part 23 is a slope 24, the connecting column 3 is provided with a slanting chip removal hole 34, the slope 24 is slanted in the same direction as the chip removal hole 34, and the slope 24 is opposite to the chip removal hole 34. The electric box cover 7 is a plastic part, and the T sleeve 8 will generate debris when being pressed into the hole position. Since the positioning pin 4 is a movable part, the debris will be brought into the cavity 31. The upper surface of the upper convex part 23 is set as a slope 24, so that the discharge can enter the chip removal hole 34 through the slope 24, so that the chip removal hole 34 discharges. Moreover, according to the needs, the middle base 2 can be disassembled for cleaning.

[0024] The working process and use method of the electric box cover pressing device of the above embodiment are briefly described as follows:

[0025] First, the hole position of the electric box cover 7 is aligned with the product positioning part 42 of the positioning pin 4, and the electric box cover 7 is placed on the product positioning surface 33, and the T sleeve 8 is placed in the position of the insert positioning step part 43 of the positioning pin 4. Start the pressing cylinder, which can drive the pressing block to move downward, push the positioning pin 4 to move downward, so as to accurately press the T sleeve 8 into the corresponding hole position. Then change other hole positions, continue to press down, until the installation of all hole positions of the T sleeve 8 is completed.

[0026] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, and not to limit them; although the embodiments of the present application are described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
