Figure 5 and Figure 6 As shown, the pump seat 02 is provided with an oil tank installation port 03 and a motor installation port 04. During installation, the pump seat 02 is placed vertically, with the oil inlet channel facing upward, and the plunger sleeve 01 is pressed downward into the oil inlet channel.

[0024] like Figures 1 to 4 As shown, the grease lubrication pump plunger sleeve riveting machine 100 of the utility model includes a support and positioning seat 10, a side thrust device 20 and a top pressing device 30. The side thrust device 20 and the support and positioning seat 10 are arranged in a left-right opposite spacing, and the side thrust device 20 and the support and positioning seat 10 enclose a positioning space 40 for placing the pump seat 02. The side thrust device 20 is used to push the pump seat 02 tightly against the support and positioning seat 10, and the top pressing device 30 is arranged above the positioning space 40, and the top pressing device 30 is used to press the plunger 01 into the pump seat 02.

[0025] In the present invention, the pump seat 02 is pushed against the support and positioning seat 10 by the side push device 20 to position the pump seat 02, and the plunger 01 is pressed into the positioned pump seat 02 by the top pressure device 30. It can be seen that the plunger sleeve 01 is pressed into the pump seat 02 when the pump seat 02 is positioned, which effectively improves the processing accuracy and does not cause the bending of the plunger sleeve 01. Moreover, no manual intervention is required for positioning and pressing, which effectively improves the processing efficiency.

[0026] Preferably, the pump seat 02 is also clamped on the support and positioning seat 10 when being pushed by the side thrust device 20, so as to strengthen the positioning of the pump seat 02. In the embodiment provided by the utility model, the support and positioning seat 10 is arranged on the left side of the side thrust device 20.

[0027] like Figures 1 to 4 As shown, the side of the support and positioning seat 10 facing the side thrust device 20 is protruded with a first protrusion 11, and the first protrusion 11 is inserted into and leans against the pump seat 02 of the support and positioning seat 10. Further, the side of the support and positioning seat 10 facing the side thrust device 20 is also protruded with a second protrusion 12, and the second protrusion 12 is inserted into and leans against the pump seat 02 of the support and positioning seat 10. Preferably, the first protrusion 11 is inserted into the oil tank installation port 03, and the second protrusion 12 is inserted into the motor installation port 04, thereby strengthening the positioning of the pump seat 02.

[0028] Since the oil tank mounting port 03 and the motor mounting port 04 are not on the same plane, but are staggered. To this end, the support positioning seat 10 is provided with a first side surface 13 and a second side surface 14 that are staggered left and right, a first protrusion 11 is provided on the first side surface 13, a second protrusion 12 is provided on the second side surface 14, and the first side surface 13 is provided above the second side surface 14 to adapt to the positions of the oil tank mounting port 03 and the motor mounting port 04. The oil tank mounting port 03 and the motor mounting port 04 are circular openings, and correspondingly, the first protrusion 11 is a circular protrusion that is inserted into the oil tank mounting port 03, and the second protrusion 12 is a circular protrusion that is inserted into the motor mounting port 04. In the embodiment provided by the utility model, the support positioning seat 10 is a flat plate structure, and a support rib is provided on the left side to support the flat plate structure.

[0029] like Figures 1 to 4 As shown, the side thrust device 20 includes a side thrust driver 21 and a side thrust rod 22. The side thrust rod 22 is installed at the output end of the side thrust driver 21. The side thrust driver 21 drives the side thrust rod 22 to move close to the support and positioning seat 10 to push the pump seat 02 tightly against the support and positioning seat 10. A plane is provided on the right side of the vertically placed pump seat, and the side thrust rod 22 is pressed on the plane to perform side thrust positioning on the pump seat 02. The area size of the plane is not particularly limited. Preferably, the side thrust driver 21 is selected as a cylinder, but is not limited thereto.

[0030] When the pump seat 02 is placed vertically, the oil inlet channel is located in the upper part of the pump seat 02. In order to position the pump seat 02 more stably, the grease lubrication pump plunger sleeve riveting machine 100 of the utility model also includes a mounting seat 50. The side push driver 21 is installed on the mounting seat 50. The side push driver 21 drives the side push rod 22 to press the right side of the pump seat 02. With the help of the mounting seat 50 to "lift" the side push driver 21, the side push rod 22 is pushed tightly against the upper part of the pump seat 02, thereby strengthening the positioning of the upper part of the pump seat 02 and ensuring the smooth progress of the riveting process.

[0031] like Figures 1 to 4 As shown, the top pressure device 30 includes a top pressure driver 31 and a press rod 32. The press rod 32 is installed at the output end of the top pressure driver 31. The top pressure driver 31 drives the press rod 32 to move downward so that the press rod 32 presses the plunger sleeve 01 into the oil inlet channel of the pump seat 02. Usually, the top pressure driver 21 drives the press rod 32 downward to press the plunger sleeve 01 into the pump seat 02. If the plunger sleeve 01 cannot be pressed in one time, the above action is repeated once or more, but it is not advisable to repeat the action too many times to avoid affecting the processing accuracy or causing the plunger sleeve 01 to bend. Preferably, the top pressure driver 31 is selected as a cylinder or an oil cylinder, but it is not limited thereto.

[0032] like Figures 1 to 4As shown, the grease lubrication pump plunger sleeve riveting machine 100 of the utility model further includes a structural support 60, the structural support 60 includes a lower platform 61 and an upper platform 62 arranged above the lower platform 61, the support positioning seat 10 and the side thrust device 20 are installed on the lower platform 61, and the top pressing device 30 is installed on the upper platform 62. The provided structural support 60 facilitates the installation and arrangement of the support positioning seat 10, the side thrust device 20 and the top pressing device 30. Preferably, the upper platform 62 and the lower platform 61 are connected by a connecting rod.

[0033] The following is a brief introduction to the use of the grease lubrication pump plunger sleeve riveting machine 100 of the utility model: put the pump seat 02 into the positioning space 40, move the pump seat 02 slightly to the left, so that the first protrusion 11 is inserted into the oil tank installation port 03, and the second protrusion 12 is inserted into the motor installation port 04. The side push driver 21 drives the side push rod 22 to move to the left, and the side push rod 22 pushes the pump seat 02 to the left, so that the pump seat 02 is tightly connected to the supporting positioning seat 10, so as to realize the positioning of the pump seat 20. Insert the plunger sleeve 01 into the oil inlet channel, and the top pressure driver 31 drives the press rod 32 to move downward, and the press rod 32 presses the plunger sleeve 01 into the pump seat 02. The side push driver 21 drives the side push rod 22 to reset, and the top pressure driver 31 drives the press rod 32 to reset, and the pump seat 02 can be taken out.

[0034] It is worth noting that an oil inlet 05 is provided at the oil tank installation port 03, and an oil suction port 06 is provided at the plunger sleeve 01. When the plunger sleeve 01 is pressed into the pump seat 02, it is necessary to ensure that the oil inlet 05 and the oil suction port 06 are kept on the same straight line on the same side.

[0035] It should be noted that Figure 3 and Figure 4 In the figure, the direction indicated by arrow X is the reverse direction from left to right, the direction indicated by arrow Y is the direction from front to back, and the direction indicated by arrow Z is the direction from bottom to top.
