[0036] To make the technical solutions and technical effects of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0037] The present utility model aims to provide a grease spraying device to replace manual smearing. The grease spraying device has a control module, mainly including a grease spray gun body 100 and a grease spray head 200 that are connected to each other. The following will specifically introduce the grease spray gun body 100 and the grease spray head 200 respectively.

[0038] Grease spray gun body 100: Refer to Figures 1-5, the grease spray gun body 100 is communicatively connected to the control module. The grease spray gun body 100 includes a base 110 which has a cavity and forms a structure that wraps the grease spray gun body 100. An atomizing air pipeline, a grease pipeline, etc. are arranged in the cavity of the base 110. A floating limit mechanism 120 and a sensor 130 are exposed on one end face of the base 110, and the floating limit mechanism 120 forms a structure that wraps the grease spray head 200. The floating limit mechanism 120 is coaxially arranged with the grease spray head 200. Specifically, the floating limit mechanism 120 includes a guide sleeve 122, a floating base 124, and a floating block 125 that are coaxially arranged. The sensor 130 senses the axial displacement of the floating block 125 under force along the guide sleeve 122 to trigger the grease spray gun body 100 to start the spraying operation; wherein: the guide sleeve 122 is fixedly installed with the base 110, and an adjusting gasket 121 is also arranged between the guide sleeve 122 and the base 110. The adjusting gasket is used to adjust the axial distance between the stepped surface of the floating block 125 and the grease nozzle 201, thereby adjusting the spraying position of the grease nozzle 201 on the inner wall of the part to be sprayed. The guide sleeve 122 has a guide post 1220, and a spring 123 is sleeved around the guide post 1220; the floating base 124 is nested and matched with the guide post 1220. Further, one end of the floating base 124 is an installation plane and is provided with installation holes, and its installation holes are correspondingly installed on the base 110 one by one with the installation holes on the installation plane at one end of the guide sleeve 122; the other end of the floating base 124 away from the base 110 is square-shaped, and floating grooves are opened on the four surrounding planes, that is, floating grooves 1240 are circumferentially spaced on the floating base 124. The floating block 125 is nested and matched with the floating base 124 and can axially displace along the floating base 124, and the floating grooves 1240 limit the displacement stroke of the floating block 125. One end of the floating block 125 is nested and matched with the floating base 124, and the other end is stepped and is provided with a circular channel that is nested and matched with the guide sleeve 122. Among them, the floating block 125 has a stepped shape for rough positioning, and the stepped part of the floating block 125 is inserted into the hole of the part to be sprayed. Further, the floating grooves 1240 are arranged along the axial direction of the floating base 124, and threaded holes corresponding to the floating grooves 1240 are circumferentially arranged on the floating block 125. Bolts 126 are fixed in the threaded holes and the bolts 126 are embedded in the floating grooves 1240. The floating block 125 has a circular channel, and a spring 123 is arranged on the nested and matched surface between the floating block 125 and the floating base 124, so that the floating block 125 can be restored under the elastic force of the spring 123 when axially displaced. Among them, the axial displacement stroke of the floating block 125 is the length of the floating groove 1240; the limit is the limit of the bolts 126 at both ends of the floating groove 1240. An opening 1251 is extended on the end face of the floating block 125 away from the floating base 124 so that the grease nozzle 201 is exposed when the floating block 125 axially displaces.The floating block 125 has a lug 1250 facing the sensor 130. The sensor 130 can sense the axial displacement of the lug 1250 as the floating block 125 moves. The sensor 130 is fixed to the base 110 through a through hole at the corresponding position on the guide sleeve 122. Further, the grease gun body 100 is also provided with a grease inlet 111, an atomizing air inlet 112, and an atomizing adjustment knob 113 respectively. The atomizing air inlet 112 is communicated with an external air source to atomize the grease transported into the grease gun body 100 from the grease inlet 111. The atomizing adjustment knob 113 is used to adjust the size of the atomizing air opening.

[0039] Grease nozzle 200: The grease nozzle 200 can circumferentially spray the grease atomized by the grease gun body 100. Further, a grease nozzle 201 is provided circumferentially at the open end of the grease nozzle 200 away from the grease gun body 100, so that the grease is circumferentially sprayed at the grease nozzle 201.

[0040] Reference Figures 6-8 , during operation:

[0041] First step, manually hold the grease spraying device of the present utility model and insert the floating block 125 of the device into the hole of the part to be sprayed. When the end face of the floating block 125 contacts the step of the part hole, it is the first in-place state;

[0042] Second step, manually continue to push the grease spraying device of the present utility model along the axial direction of the hole of the part to be sprayed until the bolt 126 on the floating block 125 reaches the limit position of the floating groove 1240. The sensor 130 senses its distance from the floating block 125 and sends a signal to the control module. This is the second in-place state;

[0043] Third step, manually press the trigger button 115. At this time, the grease gun sprays grease onto the inner wall of the hole of the part to be sprayed;

[0044] Fourth step, after spraying, manually remove the device.

[0045] It should be noted that the precondition for manually pressing the trigger button 115 to start spraying is that the sensor 130 has a signal. If the sensor 130 has no signal, pressing the trigger button 115 will not perform the spraying operation. If the trigger button 115 is pressed again after normal spraying ends, the spraying work will not be carried out either. This is controlled by the conventional program of the control module and will not be elaborated here.

[0046] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
