Description

Technical Field

[0001] This utility model relates to the field of gear grinding machine technology, and in particular to a mechanism for preventing waste chip splashing in a gear grinding machine. Background Technology

[0002] Gears are meshing toothed mechanical parts with extremely wide applications in the entire mechanical field. With the development of production, the smoothness of gear operation has become increasingly important. The emergence of gear hobbing machines and gear grinding machines has solved the problem of mass production of high-precision gears. Gear manufacturing equipment is constantly being improved. In order to complete the gear manufacturing process conveniently and simply, some auxiliary devices are often needed to cooperate with gear grinding machines for gear grinding. In order to prevent waste chips from flying during the processing, anti-splash structures are usually installed on the top of the worktable to block flying waste chips and ensure the cleanliness of the work area.

[0003] When waste chips come into contact with the splashing component, they will fall off. Since the anti-splashing structure does not have the function of collecting the waste chips, some waste chips will fall onto the surface of the workbench, which requires subsequent cleaning by relevant personnel, increasing their workload. Therefore, an anti-splashing mechanism for gear grinding machines is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mechanism for preventing waste chip splashing in a gear grinding machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a gear grinding machine anti-waste-splashing mechanism, comprising a worktable, an installation cavity on the front of the worktable, multiple material leakage holes on the top of the worktable communicating with the installation cavity, a collection drawer movably disposed within the installation cavity, two slides fixedly disposed on the top of the worktable, a common connecting plate movably disposed within the two slides, a grinding mechanism fixedly disposed on the top of the connecting plate, an installation platform fixedly disposed on the top of the worktable, a protective cover fixedly disposed on the top of the worktable, a collection assembly disposed on the inner wall of the protective cover, and two positioning structures disposed on the inner wall of the protective cover.

[0006] As a further description of the above technical solution:

[0007] The inner wall of the protective cover is fixedly provided with sound insulation cotton. The protective cover is semi-circular and the opening of the protective cover is provided with a flexible protective curtain.

[0008] As a further description of the above technical solution:

[0009] The collection assembly includes a collection box for receiving, a filter plate is movably disposed inside the collection box, and two insertion rods are fixedly disposed at the bottom of the collection box, each of the two insertion rods having a positioning hole.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the collection box is provided with two slots, and the filter plate is fixed with inserts at both ends. The slots and inserts are compatible with each other, and the top of the filter plate is fixed with two pull rods.

[0012] As a further description of the above technical solution:

[0013] The positioning structure includes a positioning block fixedly connected to the protective cover. The top of the positioning block has a round hole, and a mounting bracket is fixedly provided on one side of the positioning block. A positioning rod is movably provided on the mounting bracket.

[0014] As a further description of the above technical solution:

[0015] Both the mounting bracket and the positioning block have through holes with the same inner diameter on their front sides, and the positioning rod is movably connected to the two through holes.

[0016] As a further description of the above technical solution:

[0017] A baffle is fixedly provided on the positioning rod, and a spring is sleeved on the positioning rod. One end of the spring is in contact with the baffle, and the other end of the spring is in contact with the inner wall of one side of the mounting bracket.

[0018] As a further description of the above technical solution:

[0019] The inner walls on both sides of the mounting cavity are provided with sliding grooves, and two sliders are fixedly provided on both sides of the collection drawer. The sliders and the sliding grooves are movably connected.

[0020] This utility model has the following beneficial effects:

[0021] 1. Compared with existing technologies, the anti-waste-splashing mechanism of this gear grinding machine, through the setting of a collection box, slot, filter plate, insert block, pull rod and insert rod, ensures that the waste chips generated during grinding will fall after impacting the protective cover or sound insulation cotton. Some of them will fall into the collection drawer through the material leakage hole, while the rest will fall on the top of the filter plate. Waste chips smaller than the aperture of the filter plate will fall into the collection box. This not only achieves the collection of waste chips, but also allows for the preliminary classification and collection of waste chips of different types or sizes for subsequent recycling.

[0022] 2. Compared with the existing technology, the anti-waste splashing mechanism of this gear grinding machine is equipped with a positioning block, a round hole, a mounting bracket, a positioning rod, a baffle and a spring. When the collection box needs to be removed, the two positioning rods are pulled outward at the same time. When one end of the positioning rod comes out of the positioning hole on the insertion rod, the collection box is pulled upward to remove the collection box, which reduces the difficulty of disassembly and assembly and facilitates subsequent maintenance and cleaning.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 6This utility model provides a gear grinding machine anti-chip splashing mechanism, including a worktable 1, an installation cavity 2 on the front of the worktable 1, multiple material leakage holes 3 on the top of the worktable 1, the material leakage holes 3 communicating with the installation cavity 2, a collection drawer 4 movably installed inside the installation cavity 2, sliding grooves on both sides of the inner wall of the installation cavity 2, two sliders fixed on both sides of the collection drawer 4, the sliders and sliding grooves being movably connected, two slide seats 5 fixed on the top of the worktable 1, a connecting plate 6 movably installed inside the two slide seats 5, a grinding mechanism 7 fixed on the top of the connecting plate 6, an installation platform 8 fixed on the top of the worktable 1, a protective cover 9 fixed on the top of the worktable 1, sound insulation cotton 10 fixed on the inner wall of the protective cover 9, the protective cover 9 being semi-circular, a flexible protective curtain 13 at the opening of the protective cover 9, the flexible protective curtain 13 facilitating the entry and exit of the grinding mechanism 7, and also serving to block flying chips;

[0033] To achieve the purpose of collection, a collection assembly 11 is provided on the inner wall of the protective cover 9. The collection assembly 11 includes a collection box 111 for receiving, a filter plate 113 is movably installed inside the collection box 111, and two slots 112 are provided on the inner wall of the collection box 111. Insert blocks 114 are fixed at both ends of the filter plate 113, and the slots 112 and insert blocks 114 are compatible. Two pull rods 115 are fixed at the top of the filter plate 113, and two insert rods 116 are fixed at the bottom of the collection box 111. Both insert rods 116 are provided with positioning holes. After the waste debris hits the sound insulation cotton 10, it will fall downwards. Some of it will fall into the collection drawer 4 through the leakage hole 3, and the other part will fall onto the top of the filter plate 113. Waste debris smaller than the hole diameter of the filter plate 113 will fall into the collection box 111. This not only achieves the collection of waste debris and reduces the difficulty of subsequent cleaning, but also allows for the preliminary classification and collection of waste debris of different types or sizes for subsequent recycling.

[0034] To facilitate quick disassembly of the collection component 11, the inner wall of the protective cover 9 is provided with two positioning structures 12. Each positioning structure 12 includes a positioning block 121 fixedly connected to the protective cover 9. The top of the positioning block 121 has a round hole 122. A mounting bracket 123 is fixedly mounted on one side of the positioning block 121. A positioning rod 124 is movably mounted on the mounting bracket 123. Both the mounting bracket 123 and the positioning block 121 have through holes of the same inner diameter on their front sides. The positioning rod 124 is movably connected to both through holes. A baffle 125 is fixedly installed on the top, and a spring 126 is sleeved on the positioning rod 124. One end of the spring 126 is in contact with the baffle 125, and the other end of the spring 126 is in contact with the inner wall of one side of the mounting bracket 123. If it is necessary to remove the collection box 111, pull the two positioning rods 124 outward at the same time. When one end of the positioning rod 124 comes out of the positioning hole on the insertion rod 116, pull the collection box 111 upward to remove it. This reduces the difficulty of disassembly and assembly and facilitates subsequent maintenance and cleaning.

[0035] Working principle: In use, first lift the flexible protective curtain 13, then push the grinding mechanism 7 into the protective cover 9, and then lower the flexible protective curtain 13. The flexible protective curtain 13 facilitates the entry and exit of the grinding mechanism 7. During grinding, the waste chips generated will impact the protective cover 9. The sound insulation cotton 10 on the inner wall of the protective cover 9 can not only reduce noise, but also reduce the rebound force after the waste chips impact. The flexible protective curtain 13 can also play a blocking role, effectively preventing waste chips from splashing out from the opening. After the waste chips impact the sound insulation cotton 10, they will fall downwards. Some will fall into the collection drawer 4 through the material leakage hole 3, and the rest will fall down. At the top of the filter plate 113, waste particles smaller than the aperture of the filter plate 113 will fall into the collection box 111. This not only collects the waste particles, but also allows for the preliminary classification and collection of waste particles of different types or sizes for subsequent recycling. When the filter plate 113 needs to be cleaned, hold the two pull rods 115 and pull them upward to remove the filter plate 113 from the collection box 111. When the collection box 111 needs to be removed, pull the two positioning rods 124 outward at the same time. When one end of the positioning rod 124 comes out of the positioning hole on the insertion rod 116, pull the collection box 111 upward to remove it.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
