Description

Technical Field

[0001] This application relates to the technical field of gantry filter processing, and in particular to a dotting mechanism for gantry filter processing. Background Art

[0002] A gantry machine tool is a heavy-duty machine tool, usually used for processing larger workpieces. Inside the machine body, since a large amount of metal chips and cuttings are generated during the working process of the cutting fluid, a filter screen is required to filter these impurities, so as to ensure the cleanliness of the working fluid and extend the service life of the machine tool and the cutting tool. Ordinary CNC gantry machine tools usually only require one filter screen, which is installed at the inlet of the cutting fluid tank to filter metal chips and sediments, so as to keep the cutting fluid clean; High-speed CNC gantry machine tools usually require two filter screens, one at the inlet of the cutting fluid tank to filter metal chips and sediments, and the other at the suction port of the cutting fluid pump to filter fine particles in the cutting fluid and keep the cutting fluid clean at the same time; Ultra-precision CNC gantry machine tools require three filter screens due to extremely high processing requirements, namely a primary filter screen, a high-performance filter screen and an ultra-precision filter screen, to achieve the optimal management of the entire processing process. Generally speaking, different types of gantry machine tools require different numbers of filter screens, but their functions are the same. During the working process, the role of the filter screen cannot be ignored. Only by replacing and cleaning the filter screen in time can the cleanliness of the cutting fluid be truly ensured, and then the stability of the machine and the processing quality can be ensured.

[0003] After checking the publication number: CN 205645084 U, a dual-purpose dotting mechanism is disclosed. In this technology, "including a fixing plate, a base, a cage, a fixed seat, a first cylinder, a second cylinder, a return spring, an ink supply head and a connector; a base is fixed on the fixing plate, a cage is slidably installed on the base, a return spring is provided between the cage and the base, a fixed seat is fixed on the cage, and an ink supply head is installed on the fixed seat and the cage; a first cylinder and a second cylinder are fixed on the base, the first cylinder is arranged parallel above the second cylinder, the piston rod of the first cylinder abuts against the cage, and a connector is installed at the end of the piston rod of the second cylinder" and other technical solutions, which have the technical effects of being able to freely switch the pneumatic ink supply head or the electric ink supply head according to work needs, being not only convenient to use, fully functional but also simple and reliable in structure.

[0004] In view of the above related technologies, the inventor believes that the production and processing effect of the existing gantry lathe filter screen is limited, and the effect of the dotting work is not good. Since the filter screen needs to be aligned and positioned during installation, if the efficiency of the dotting structure is low, it will affect the production speed of the filter screen, and the stability of the workpiece placement is not good. If the workpiece is not firmly placed, it will affect the quality of the dotting, thus affecting the quality of the produced filter screen. Therefore, a dotting mechanism for gantry filter processing is needed to solve the above problems. Content of the Utility Model

[0030] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 3 , and make a further detailed description of the present application.

[0031] Embodiment 1

[0032] A dotting mechanism for processing a gantry filter screen, referring to Figure 1-2 , includes a bottom plate 1. A bracket 2 is fixedly provided at the upper end of the bottom plate 1. A cylinder 3 is fixedly provided at the upper end of the bracket 2. The output end of the cylinder 3 penetrates through the bracket 2 and is fixedly connected to a lifting plate 6. A plurality of push columns 61 and two fixed columns 62 are fixedly provided at the lower end of the lifting plate 6. A support plate 63 is fixedly provided at one end of the bracket 2. A limiting rod 7 is fixedly provided at one end of the support plate 63. A limiting block 71 is fixedly provided at the lower end of the limiting rod 7. Needle grooves 72 for cooperating with the push columns 61 are provided at the upper ends of the limiting rod 7 and the limiting block 71. An ejector pin 723 is placed in the needle groove 72. A push plate 721 is fixedly provided at the upper end of the ejector pin 723. A first spring 722 is fixedly provided between the push plate 721 and the lower inner wall of the needle groove 72 on the limiting rod 7. The bottom plate 1 serves as a carrier. The cylinder 3 on the bracket 2 is started, so that the lifting plate 6 descends. At this time, the push columns 61 and the fixed columns 62 on the lifting plate 6 move downward. When the push column 61 enters the needle groove 72 on the limiting rod 7, the ejector pin 723 is pushed out from below the limiting block 71, and the dotting work is completed through the ejector pin 723. The limiting rod 7 is fixed on the bracket 2 through the support plate 63, and the connection strength is relatively high. After the dotting work is completed, due to the traction of the first spring 722 at the lower end of the push plate 721, the ejector pin 723 returns to its position, which is convenient for the next dotting work, and the dotting is convenient and the efficiency is relatively high.

[0033] Referring to Figure 1 , a reinforcing block 4 is fixedly provided on the upper inner wall of the bracket 2. The reinforcing block 4 is connected through the output end of the cylinder 3, which improves the stability of the output of the cylinder 3.

[0034] Referring to Figure 2 , there are six push columns 61, and the six push columns 61 are distributed in a rectangular array, which can punch six points at one time and the positioning effect is better.

[0035] Referring to Figure 2, two vertical plates 64 are fixedly provided at the upper end of the support plate 63. Clamping blocks 65 are fixedly provided at both ends of the lifting plate 6, and a clamping groove 66 for cooperating with the clamping block 65 is formed at the inner end of the vertical plate 64. The clamping block 65 on the lifting plate 6 slides up and down in the clamping groove 66 on the vertical plate 64, improving the lifting effect of the lifting plate 6.

[0036] Referring to Figure 2 , fixing grooves 73 for cooperating with the fixing column 62 are formed at the upper ends of the limiting rod 7 and the limiting block 71. A sliding column 74 is arranged in the fixing groove 73 on the limiting block 71. A third spring 75 is fixedly provided at the lower end of the sliding column 74, and a contact disc 76 is fixedly provided at the lower end of the third spring 75. When the lifting plate 6 descends, the fixing column 62 enters the fixing groove 73, then contacts the sliding column 74 and pushes the sliding column 74 to move downward. The sliding column 74 drives the contact disc 76 to contact the workpiece to be processed through the third spring 75. Before the ejector pin 723 makes a dot, the contact disc 76 first fixes the workpiece through the third spring 75 to improve the dotting effect.

[0037] Referring to Figure 2 , the push plate 721 is in movable contact with the inner wall of the needle groove 72 corresponding to the position on the limiting rod 7, making the lifting stability of the push plate 721 better.

[0038] The implementation principle of the embodiment of the present application is as follows: The bottom plate 1 serves as a carrier. The air cylinder 3 on the bracket 2 is started, causing the lifting plate 6 to descend. At this time, the push column 61 and the fixing column 62 on the lifting plate 6 move downward. When the push column 61 enters the needle groove 72 on the limiting rod 7, it pushes the ejector pin 723 to be pushed out from below the limiting block 71, and the dotting work is completed through the ejector pin 723. The limiting rod 7 is fixed on the bracket 2 through the support plate 63, and the connection strength is relatively high. After the dotting work is completed, due to the traction of the first spring 722 at the lower end of the push plate 721, the ejector pin 723 returns to its original position, facilitating the next dotting work. The dotting is convenient and the efficiency is relatively high;

[0039] The strengthening block 4 improves the stability of the output of the air cylinder 3. The clamping block 65 on the lifting plate 6 slides up and down in the clamping groove 66 on the vertical plate 64, improving the lifting effect of the lifting plate 6;

[0040] Six points can be dotted at one time, and the positioning effect is better;

[0041] When the lifting plate 6 descends, the fixing column 62 enters the fixing groove 73, then contacts the sliding column 74 and pushes the sliding column 74 to move downward. The sliding column 74 drives the contact disc 76 to contact the workpiece to be processed through the third spring 75. Before the ejector pin 723 makes a dot, the contact disc 76 first fixes the workpiece through the third spring 75 to improve the dotting effect.
