Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to a cleaning device that facilitates the cleaning of impurities inside workpiece holes. Background Technology

[0002] An oil nozzle is a metal workpiece that requires press-fitting its inner hole during production. This means that the oil nozzle already has a center hole when it arrives from the upstream process. The purpose of this process is to press-fit this center hole into a stepped hole. During this press-fitting process, the center hole of the incoming oil nozzle needs to be cleaned to ensure the accuracy of subsequent forming. The existing cleaning method involves manual blowing with a dust gun. This method has several drawbacks: firstly, it requires manual labor with low automation; secondly, because the center hole is relatively deep, some impurities remain at the bottom, making direct blowing ineffective; and thirdly, the blown-out impurities easily disperse into the workshop air, polluting the environment. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a cleaning device that facilitates the cleaning of impurities inside workpiece holes. It can automatically clean residues, waste chips and other impurities that are stuck or attached to the workpiece, and the cleaning effect is good. In particular, it can automatically clean relatively deep holes in the workpiece, improve the degree of automation and reduce labor costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a cleaning device is provided to facilitate the cleaning of impurities in the holes of workpieces. The cleaning device includes a cleaning bracket and a cleaning lifting drive module, a cleaning seat, an ejector pin assembly and an ejector pin lifting drive cylinder installed on the cleaning bracket. The cleaning seat is installed on the cleaning lifting drive module and is driven to lift and lower by the cleaning lifting drive module.

[0005] The cleaning seat includes an upper seat, a middle seat, and a base from top to bottom. The upper end of the ejector pin assembly passes through the middle seat and is fixed to the power output end of the ejector pin lifting drive cylinder, and the lower end passes through the base and can extend out. The upper end of the ejector pin assembly is connected to an upper air blowing connector.

[0006] The base has a first cavity inside, one side of which is connected to an air blowing connector and the other side is connected to an air suction seat. The air suction seat has a second cavity inside, and the other side of the second cavity is connected to an air suction connector. The bottom surface of the first cavity of the base can be engaged with a carrier for placing workpieces.

[0007] Furthermore, the ejector assembly includes a cylindrical and hollow ejector seat and an ejector pin. A sealing guide sleeve is provided on the top of the seat. The upper end of the ejector seat is installed on the power output end of the ejector pin lifting drive cylinder, and the lower end passes through the sealing guide sleeve. The upper end of the ejector pin is fixedly installed on the lower end of the ejector seat.

[0008] The upper end of the ejector pin seat is connected to the upper air blowing connector.

[0009] Furthermore, the lower surface of the base has a circular hole that can be sealed and engaged with a circular protrusion on the carrier.

[0010] Furthermore, the air outlet of the side-blowing connector is horizontally positioned; the impurities on the surface of the vehicle are directed vertically into the second cavity through the side-blowing connector.

[0011] Furthermore, the inner bottom surface of the base is flush with the inner bottom surface of the air intake seat.

[0012] Furthermore, the ejector pin lifting drive cylinder is fixedly installed on the upper seat.

[0013] The beneficial effects of this utility model are:

[0014] This utility model features an ingenious and reasonable structural design. A cylinder drives the ejector pin to first poke up any residue, debris, or other impurities adhering to or attached to the center hole of the workpiece. Then, gas is used to blow these impurities away. Finally, an external suction device collects and centrally processes the impurities. Therefore, this utility model automatically cleans residue, debris, and other impurities adhering to or attached to workpieces with excellent cleaning results. It is particularly effective at automatically cleaning deep holes in workpieces, improving automation and reducing labor costs.

Those skilled in the art can easily understand the advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented in other different ways, that is, different modifications and changes can be made without departing from the scope disclosed in this utility model.

[0025] The descriptions of positions such as up, down, left, and right in this embodiment are based on the orientation in the accompanying drawings, have no special meaning, and are not intended to limit the scope of protection of this utility model.

[0026] Example: A cleaning device for facilitating the removal of impurities inside workpiece holes, such as... Figures 1 to 5 As shown, the cleaning device 1 includes a cleaning bracket 16 and a cleaning lifting drive module 11, a cleaning seat 12, a pin assembly 13 and a pin lifting drive cylinder 14 mounted on the cleaning bracket. The cleaning seat is mounted on the cleaning lifting drive module and is driven to lift and lower by the cleaning lifting drive module.

[0027] The cleaning seat 12 includes an upper seat 121, a middle seat 122 and a base 123 from top to bottom. The upper end of the ejector pin assembly passes through the middle seat and is fixed to the power output end of the ejector pin lifting drive cylinder, and the lower end passes through the base and can extend out. The upper end of the ejector pin assembly is connected to an upper air blowing connector 133.

[0028] The base has a first cavity 1231 inside. One side of the first cavity is connected to a blower 1232, and the other side is connected to a suction seat 15. The suction seat has a second cavity 151 inside. The other side of the second cavity is connected to a suction connector 152. The bottom surface of the first cavity of the base can be engaged with a carrier 20 for placing the workpiece 10.

[0029] In this embodiment, the ejector assembly 13 includes a cylindrical and hollow ejector seat 131 and an ejector 132. A sealing guide sleeve 1221 is provided on the top of the seat. The upper end of the ejector seat is installed on the power output end of the ejector lifting drive cylinder, and the lower end passes through the sealing guide sleeve. The upper end of the ejector is fixedly installed on the lower end of the ejector seat.

[0030] The upper end of the ejector pin seat is connected to the upper air blowing connector.

[0031] The sealing guide sleeve is used to ensure a tight seal between the ejector pin seat and the cleaning seat during the lifting and lowering process.

[0032] In this embodiment, the lower surface of the base has a circular hole 1233, which can be sealed and engaged with the circular protrusion 201 on the carrier. This structure ensures the sealing effect after the base and carrier are engaged, thereby ensuring the sealing performance and the effectiveness of the cleaning device in removing impurities.

[0033] In this embodiment, the air outlet of the side-blowing air connector is horizontally positioned; the side-blowing air connector directs impurities on the surface of the carrier vertically into the second cavity. The side-blowing air connector blows impurities and dust from the surface of the carrier and workpiece into the second cavity, facilitating better extraction of dust, slag, and other impurities, ensuring effective extraction.

[0034] In this embodiment, the inner bottom surface of the base is flush with the inner bottom surface of the suction seat. This is to ensure that impurities at the bottom of the first cavity can more easily enter the second cavity, thus ensuring the final cleaning effect.

[0035] In this embodiment, the ejector pin lifting drive cylinder is fixedly installed on the upper seat.

[0036] In this embodiment, the upper air blowing connector and the side air blowing connector are connected to external air blowing devices, and the air suction connector is connected to external air suction devices.

[0037] The working principle and process of this utility model:

[0038] The workpiece to be cleaned (such as an oil nozzle) is placed on the carrier. After the cleaning lifting drive module drives the cleaning seat to descend into position, the ejector pin lifting drive cylinder drives the ejector pin seat and ejector pin to descend until the ejector pin inserts into the bottom of the center hole of the workpiece. This will poke up the residue and other impurities that are stuck to or attached to the hole wall and bottom of the center hole. Then, air is blown through the upper air blowing connector. The air is blown along the bottom of the ejector pin seat and ejector pin to the bottom and hole wall of the center hole, blowing up the previously poked impurities and blowing them into the first cavity. Then, the side air blowing connector blows the impurities and dust on the surface of the carrier and workpiece into the second cavity. The impurities are collected by the external air extraction device to ensure the cleaning effect of the workpiece.

[0039] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model.
