Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of tail gas filters, in particular to a tail gas filter housing fine processing positioning mechanism. Background Art

[0002] An exhaust filter is a device used to filter and purify exhaust gas emitted by various equipment (such as automobiles, industrial machinery, etc.). Its main functions include reducing harmful substances in exhaust gas, protecting the environment, reducing harm to human health, and promoting the development of environmental protection. Specifically, the exhaust filter can absorb, decompose and transform incompletely burned residues in exhaust gas into harmless substances. Exhaust filters are usually installed at the exhaust outlets of automobiles and industrial equipment to filter and purify the exhaust gas emitted by these equipment.

[0003] At present, when the exhaust gas filter shell is being processed, although there will be a pin for positioning during processing, there will be a certain amount of squeezing when the shell touches the pin. Such squeezing will cause a slight deviation in the fixation of the shell, causing the processing position to move a little. When the processing requirements need to be particularly precise, such processing deviation will lead to processing errors, causing the workpiece to fail and be scrapped, resulting in economic losses. Therefore, it is necessary to design an exhaust gas filter shell finishing positioning mechanism that can accurately position the shell during processing and prevent the shell from moving. Utility Model Content

[0004] In order to solve the technical problem that when an ejector pin is used to position an exhaust gas filter housing, the housing may be moved, the utility model provides an exhaust gas filter housing finishing positioning mechanism.

[0005] The utility model is implemented by the following technical scheme: a tail gas filter housing finishing positioning mechanism, comprising a processing housing, a processing flange is fixedly installed on one side of the processing housing, a positioning component for processing and positioning the processing housing is provided on one side of the processing housing, a driving component for driving the positioning component to position the processing housing is provided on the positioning component, and a mounting component for mounting the positioning component on a machine table is provided on one side of the positioning component.

[0006] Through the above technical solution, when the processing shell and the processing flange are being processed, the driving component allows the positioning component to move to expand and position the processing shell and the processing flange.

[0007] As a further improvement of the above scheme, the positioning assembly includes a positioning base with multiple sliding grooves, a positioning block slidably installed inside each sliding groove, and a movable ring fixedly installed on one side of each positioning block, and a top block is fixedly installed on one side of each positioning block.

[0008] Through the above technical solution, the top block can be opened by a plurality of positioning blocks, so that the processing shell can be opened and fixed inside the processing shell.

[0009] As a further improvement of the above scheme, a mounting hole that passes through the positioning base is opened on one side of the positioning base, and the driving assembly includes a first bidirectional threaded rod arranged inside the mounting hole and a second bidirectional threaded rod arranged inside the mounting hole on one side of the first bidirectional threaded rod, and both ends of the first bidirectional threaded rod and the second bidirectional threaded rod are threaded through adjacent movable rings.

[0010] Through the above technical solution, the corresponding positioning block can be moved by rotating the first bidirectional threaded rod and the second bidirectional threaded rod.

[0011] As a further improvement of the above scheme, a first helical gear is fixedly sleeved on the first bidirectional threaded rod, and a second helical gear meshing with the first helical gear is fixedly sleeved on the second bidirectional threaded rod. A limit frame in the shape of a "mouth" is provided inside the mounting hole, and the first bidirectional threaded rod and the second bidirectional threaded rod are both rotatably matched with the limit frame.

[0012] Through the above technical solution, the rotation of the first bidirectional threaded rod will cause the first helical gear to rotate, thereby causing the second helical gear to drive the second bidirectional threaded rod to rotate.

[0013] As a further improvement of the above solution, a square hole is formed at one end of the first bidirectional threaded rod, a square block is inserted into the square hole, and a control handle is fixedly mounted at one end of the square block.

[0014] Through the above technical solution, the first bidirectional threaded rod and the second bidirectional threaded rod can be rotated together by rotating the control handle in coordination with the first helical gear and the second helical gear.

[0015] As a further improvement of the above solution, the mounting assembly includes a mounting plate fixedly mounted on one side of the positioning base and a mounting column fixedly mounted on one side of the mounting plate, and one side of the limit frame is fixedly mounted on one side of the mounting plate.

[0016] Through the above technical solution, the mounting plate cooperates with the mounting column to fix the positioning assembly on the processing machine tool.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model sets a positioning component, a driving component and an installation component, and uses the installation component to install the positioning component and the driving component on the machine platform. When processing the processing flange, the driving component can be used to expand the positioning component, and the processing shell can be fixed when the positioning component is expanded inside the processing shell. This arrangement allows the processing shell to be positioned with a uniform force during positioning, thereby avoiding the offset of the processing flange and the processing shell caused by the positioning of the ejector pin.

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Please combine Figure 1-Figure 4 A finishing positioning mechanism for an exhaust gas filter housing in this embodiment includes a processing housing 1, a processing flange 2 is fixedly installed on one side of the processing housing 1, a positioning component for processing and positioning the processing housing 1 is provided on one side of the processing housing 1, a driving component for driving the positioning component to position the processing housing 1 is provided on the positioning component, and a mounting component for mounting the positioning component on a machine platform is provided on one side of the positioning component.

[0027] Combination Figure 1-Figure 3The positioning assembly includes a positioning base 301 with multiple sliding grooves, a positioning block 302 slidably installed inside each sliding groove, and a moving ring 303 fixedly installed on one side of each positioning block 302. A top block 6 is fixedly installed on one side of each positioning block 302. When multiple positioning blocks 302 are unfolded, the top block 6 is pushed against the inside of the processing shell 1 to open and fix the processing shell 1.

[0028] Combination Figure 2-Figure 4 A mounting hole penetrating the positioning base 301 is provided on one side of the positioning base 301, and the driving assembly includes a first bidirectional threaded rod 401 arranged inside the mounting hole and a second bidirectional threaded rod 402 arranged inside the mounting hole and located on one side of the first bidirectional threaded rod 401. Both ends of the first bidirectional threaded rod 401 and the second bidirectional threaded rod 402 are threadedly penetrated through the adjacent moving ring 303. A first helical gear 7 is fixedly sleeved on the first bidirectional threaded rod 401, and a second helical gear 8 meshing with the first helical gear 7 is fixedly sleeved on the second bidirectional threaded rod 402. A "mouth" is provided inside the mounting hole. The limiting frame 9 is arranged in the shape of a Chinese character "", the first bidirectional threaded rod 401 and the second bidirectional threaded rod 402 are both rotatably matched with the limiting frame 9, one end of the first bidirectional threaded rod 401 is provided with a square hole, a square block 10 is inserted into the inside of the square hole, and a control handle 11 is fixedly installed at one end of the square block 10. By rotating the control handle 11 to cooperate with the first helical gear 7 and the second helical gear 8, the first bidirectional threaded rod 401 and the second bidirectional threaded rod 402 can be rotated together, and the corresponding positioning block 302 can be moved by rotating the first bidirectional threaded rod 401 and the second bidirectional threaded rod 402.

[0029] Combination Figure 1 and Figure 3 The mounting assembly includes a mounting plate 501 fixedly mounted on one side of the positioning base 301 and a mounting column 502 fixedly mounted on one side of the mounting plate 501. One side of the limit frame 9 is fixedly mounted on one side of the mounting plate 501. The mounting plate 501 cooperates with the mounting column 502 to fix the positioning assembly on the processing machine tool.

[0030] The implementation principle of a tail gas filter housing finishing positioning mechanism in the embodiment of the present application is as follows: when performing positioning processing on the processing flange 2, the machine table pushes the processing housing 1 to move. When the processing flange 2 moves to the processing position, the control handle 11 and the square block 10 are inserted into the square hole of the first bidirectional threaded rod 401 and rotated. The rotation of the first bidirectional threaded rod 401 will rotate the first helical gear 7, thereby driving the second helical gear 8 to rotate. The rotation of the second helical gear 8 will rotate the second bidirectional threaded rod 402. In this way, the first bidirectional threaded rod 401 and the second bidirectional threaded rod 402 will rotate at the same time. Because of the limit position of the limit frame 9, the two bidirectional threaded rods will only rotate. It will not move, but the moving ring 303 that is threadedly matched with the two bidirectional threaded rods will be fixedly installed with the positioning block 302, and the positioning block 302 is limited by the sliding groove, so the moving ring 303 will move with the positioning block 302, and according to the rotation direction of the control handle 11, all the positioning blocks 302 will be expanded and moved, so that the positioning block 302 will push the top block 6 to position and support the inner wall of the processing shell 1, so that the position of the processing shell 1 will be accurately positioned, and the processing flange 2 will also be accurately positioned. This setting allows the processing shell 1 to be positioned with uniform force during positioning, avoiding the use of the ejector pin to cause the processing flange 2 and the processing shell 1 to be offset.

[0031] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
