[0029] In order to make the person skilled in the art better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.
[0030] Referring to the drawings Figures 1-5 The compressor one-way valve press-fitting equipment in the embodiment includes a positioning base 5 for placing a compressor rear cover 6, a stamping mechanism 2 is arranged vertically above the positioning base 5, the stamping mechanism 2 is used for press-fitting a one-way valve 8 with the compressor rear cover 6, a top pressure device 9 is arranged along the valve hole position of the compressor rear cover 6, the top end of the top pressure device 9 protrudes from the surface of the positioning base 5, and is used for leaving a pressure mark on the compressor rear cover 6 during press-fitting.
[0031] When the operator needs to install the one-way valve 8 into the compressor rear cover 6, the operator places the compressor rear cover 6 on the positioning base 5 and places the one-way valve 8, starts the stamping mechanism 2, and the stamping mechanism 2 performs stamping along the vertical direction to press-fit the one-way valve 8 with the compressor rear cover 6 into place. At this time, the top pressure device 9 arranged on the positioning base 5 is displaced downward and touches the top pressure device 9 during the process that the compressor rear cover 6 is impacted by the stamping mechanism 2. The top pressure device 9 leaves a pressure mark on the back of the position where the one-way valve 8 is installed on the compressor rear cover 6, indicating that the one-way valve 8 at this position has been installed. In the later stage, after the compressor rear cover 6 is assembled into the compressor, it is easy to judge that the one-way valve 8 in the compressor has been installed by the pressure mark left by the compressor rear cover 6, and there is no need for the detection personnel to detect whether the one-way valve 8 has been installed by additional methods and means, thereby saving the time and effort of the detection personnel, saving the cost of purchasing detection equipment, and saving the cost.
[0032] In another embodiment, as Figure 3As shown, the top pressing device 9 includes a punch 92, the punch 92 protrudes from the surface of the positioning base 5, and the bottom end is provided with a locking screw 91. When the punch mechanism 2 is punched along the vertical direction, and the one-way valve 8 is pressed and assembled with the compressor rear cover 6, the compressor rear cover 6 is subjected to the impact force brought by the punch mechanism 2, and is displaced downward to touch the punch 92. The punch 92 leaves an indentation on the back of the position where the one-way valve 8 is installed on the compressor rear cover 6, indicating that the one-way valve 8 at this position has been installed. Later, after the compressor rear cover 6 is assembled to the compressor, the inspector detects the indentation left by the compressor rear cover 6 to determine that the one-way valve 8 in the compressor has been installed. The inspector does not need to detect whether the one-way valve 8 has been installed by additional methods and means, saving the inspector's time and effort, and saving the cost of purchasing detection equipment.
[0033] In another embodiment, as shown in Figure 1 The punch mechanism 2 includes a servo press 21, and the output end of the servo press 21 is connected with a pressing rod 23. When the operator starts the device, the servo press 21 drives the pressing rod 23 downward along the vertical direction to punch, and drives the one-way valve 8 to be pressed and assembled with the compressor rear cover 6, so that the one-way valve 8 is pressed and assembled with the compressor rear cover 6.
[0034] Specifically, the output end of the servo press 21 is connected with the pressing rod 23 through a connecting flange 22. When the device needs to be repaired or maintained, the pressing rod 23 can be disassembled from the servo press 21 by disassembling the connecting flange 22, so as to save the maintenance cost.
[0035] In another embodiment, as shown in Figure 1 The device frame 1 is further provided with a workbench for mounting the positioning base 5, and the punch mechanism 2 is fixedly connected with the device frame 1.
[0036] In another embodiment, as shown in Figure 1 The device frame 1 is further provided with a safety light barrier 4. When the servo press 21 drives the pressing rod 23 to punch downward along the vertical direction, and the operator's body accidentally enters the dangerous area, the safety light barrier 4 can control the servo press 21 to stop working, so as to avoid causing the operator's body to be injured.
[0037] In another embodiment, as shown in Figure 2 And Figure 3As shown, the device further comprises a pressure head 7, a brake distance is provided between the pressure rod 23 and the pressure head 7, the pressure head 7 is arranged in the stamping direction of the pressure rod 23, and the upper surface of the one-way valve 8 is in abutment with the lower surface of the pressure head 7 away from the pressure rod 23. When the operator starts the device, the servo press 21 drives the pressure rod 23 to move downward in the vertical direction, and the pressure rod 23 moves downward to contact the pressure head 7, and drives the pressure head 7 to move downward, and the pressure head 7 drives the one-way valve 8 to move downward and is pressed and assembled with the compressor rear cover 6, so that the one-way valve 8 is assembled with the compressor rear cover 6.
[0038] In another embodiment, as shown in Figure 1 , the servo press 21 is electrically connected with a servo press controller 3, the servo press controller 3 is a control device carried by the servo press 21 itself, the servo press controller 3 is fixedly installed on the equipment frame 1, and the servo press controller 3 is used to control the press assembly displacement and the press assembly pressure, so as to facilitate better operation of the equipment.
[0039] Specifically, the model of the servo press controller 3 is Nidec DA21224.
[0040] In another embodiment, as shown in Figure 4 、 Figure 5 、 Figure 6 , the positioning base 5 is designed in a profiled manner, and is used to match the compressor rear cover 6, so that the compressor rear cover 6 can be better matched together with the positioning base 5.
[0041] Specifically, the compressor rear cover 6 is provided with a valve hole 62, the valve hole 62 is used to connect the one-way valve 8 with the compressor rear cover 6, and the positioning base 5 is provided with a positioning hole 51, the positioning hole 51 is used to match the valve hole 62.
[0042] Specifically, the positioning base 5 is provided with different types of specifications, and can be suitable for different types of compressor rear covers 6, when different types of compressors need to be stamped, the operator replaces the positioning base 5 on the workbench with a suitable type, and performs stamping, thereby improving the universality of the equipment.
[0043] The above-mentioned embodiments only express certain embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application; it should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, the protection scope of the present application should be subject to the appended claims.
