An adjustable cutter assembly for cutting air conditioning filters.

Abstract

This invention discloses an adjustable tool assembly for cutting air conditioning filters, including a drill bit, a tool shank, a mating tool, a plug-in post, a threaded post, a threaded disc, a control component, and a plug-in component. Through the plug-in plate and a lifting plate, the lifting plate moves along the mating tool, causing the plug-in plate to slide out of the plug-in slot, but the lifting plate does not disengage from the mating tool. The position of the mating tool is adjusted dynamically, and the corresponding rotation control component rotates synchronously. When the threaded disc rotates and moves within the threaded hole, the plug-in post and the threaded post move in the same direction but do not rotate. Furthermore, the movement efficiency of the plug-in post and the threaded post is greater than that of the threaded disc, thus completing the adjustment and achieving high stability after adjustment. The engagement of the threaded disc with the threaded rod and the threaded hole effectively prevents reverse reset, and the adaptive engagement allows the mating tool to move. Finally, the first connecting hole, the second connecting hole, and the connecting plate further reinforce the fixation of the adjusted mating tool on the drill bit.

Description

Technical Field

[0001] This invention relates to the field of cutting tool assembly structure technology, specifically an adjustable cutting tool assembly for cutting air conditioning filters. Background Technology

[0002] In the production of air conditioning filters, cutting and drilling are crucial processes. Currently, most existing air conditioning filter cutting tool assemblies on the market have the problem of being non-adjustable. Generally, the cutting tools are fixed in a specific position, and parameters such as the angle and height of the blades and the spacing between the tools cannot be adjusted according to actual production needs.

[0003] This type of non-adjustable cutter assembly has many drawbacks. On the one hand, when cutting air conditioning filters of different specifications and materials, the fixed cutter parameters cannot accurately adapt to the cutting requirements of different filters, resulting in poor cutting results, such as uneven cut edges and burrs, which affect the quality and performance of the filter. On the other hand, after prolonged use, the non-adjustable cutter assembly will experience wear and tear. Since the cutter parameters cannot be fine-tuned to compensate for the wear, the entire cutter assembly must be replaced, increasing production costs and equipment maintenance difficulty.

[0004] Therefore, we propose an adjustable tool assembly for cutting air conditioning filters. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable cutting tool assembly for cutting air conditioning filters, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides an adjustable tool assembly for cutting air conditioning filters, including a drill bit and a tool shank fixedly mounted to the drill bit.

[0007] It also includes multiple sets of mating tools connected to the drill bit. Each mating tool has a plug-in post, and a threaded post is fixedly connected to the end of the plug-in post. A threaded disc that is threaded to the drill bit is threaded to the outer surface of the threaded post. The threaded disc is provided with a control component that controls the rotation of the threaded disc. The control component can be slidably stored inside the drill bit.

[0008] Furthermore, a connector is provided between the mating tool and the drill bit, and the connector can adjust the position of the mating tool on the drill bit.

[0009] Furthermore, the drill bit has a threaded hole that is threaded to the threaded disc, and the drill bit is fixedly connected to a sleeve that is movably fitted to the insertion post, and the sleeve is connected to the threaded hole.

[0010] Furthermore, the control component includes a plunger that movably engages with a threaded hole, and a plurality of limiting rods that penetrate the threaded disc are fixedly connected to the plunger.

[0011] Furthermore, a pressing member is fixedly connected to the end of the threaded column, a pressing groove is provided on one side of the plug to press against the pressing member, and a cross groove is provided on the other side of the plug.

[0012] Furthermore, the edge of the pressing member is inclined, the side of the pressing groove is inclined at an angle, the inclination angle of the edge of the pressing member is greater than the inclination angle of the side of the pressing groove, and an anti-slip layer is provided at the edge of the pressing member.

[0013] Furthermore, the plug-in post has a T-shaped cross-section, an annular groove is provided at the end of the plug-in post, and a limiting disc is fixedly connected to the end of the pressing member to press and fix against the annular groove.

[0014] Furthermore, the connector includes a connector and a connector plate that is fixedly installed with the mating tool. The drill bit has multiple sets of connector slots that are mated with the connector plate. The mating tool has a first connecting hole and multiple second connecting holes. The connector is fixedly connected to the first connecting hole and the second connecting holes.

[0015] Furthermore, the plug-in plate is connected and fixed by a connecting plate and two connecting rods, and the height of the connecting plate is greater than the height of the connecting rods.

[0016] Furthermore, a connecting plate is fixedly connected to the end of the insert post that extends into the mating tool. The connecting plate corresponds to the first connecting hole, and the connecting member passes through the middle of the connecting plate.

[0017] Furthermore, a lifting plate that engages with the mating tool is fixedly connected to the plug-in plate to ensure the connection between the plug-in plate and the mating tool.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The insertion plate and the lifting plate move along the mating tool, causing the insertion plate to slide out of the insertion slot, but the lifting plate will not disengage from the mating tool.

[0020] The position of the moving adjustment tool is synchronized with the corresponding rotation control component. When the threaded disc rotates and moves in the threaded hole, the insertion post and the threaded post move in the same direction but do not rotate. Moreover, the moving efficiency of the insertion post and the threaded post is greater than the moving efficiency of the threaded disc, thus completing the adjustment in coordination, and the stability after adjustment is high.

[0021] Furthermore, the engagement of the threaded disc, threaded rod, and threaded hole effectively prevents reverse reset, and the adaptive engagement allows the mating tool to move. Finally, the first connecting hole, the second connecting hole, and the connecting plate further reinforce the fixation of the mating tool on the drill bit head after the position adjustment.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-11 This invention provides an adjustable tool assembly for cutting air conditioning filters, including a drill bit 1 and a tool shank 2 fixed to the drill bit 1. In the prior art, the drill bit 1 is fixed on the tool shank 2. This application adds a matching tool 3 to the conventional drill bit 1 and allows the position of the matching tool 3 to be adjusted on the drill bit 1, thereby increasing applicability.

[0036] It also includes multiple sets of mating cutting tools 3 connected to the drill bit 1, connecting parts 20, and plug-in plates 16 that are installed and fixed with the mating cutting tools 3. The drill bit 1 has multiple sets of plug-in slots 17 that are plugged into and mated with the plug-in plates 16.

[0037] The drill bit 1 has a threaded hole 7 that is threadedly connected to the threaded disc 6;

[0038] In the initial state, the threaded disc 6 is in the threaded hole 7. When it is necessary to adjust the position of the mating tool 3, the threaded disc 6 is always in the threaded hole 7.

[0039] First, the insertion plate 16 is separated from the mating tool 3. The insertion plate 16 is fixedly connected to a lifting plate 22 that is inserted and mated with the mating tool 3. The lifting plate 22 moves along the mating tool 3, so that the insertion plate 16 slides out of the insertion groove 17, but the lifting plate 22 will not detach from the mating tool 3.

[0040] Then, the position of the moving and adjusting tool 3 is adjusted, and the corresponding rotation control component is synchronously adjusted to make the moving tool 3 move. The moving tool 3 is provided with a first connecting hole 18, and the drill bit 1 is provided with multiple second connecting holes 19.

[0041] Finally, the first connecting hole 18 on the adjusted mating tool 3 corresponds to one of the second connecting holes 19, and the end of the insert post 4 extending into the mating tool 3 is fixedly connected to a connecting plate 21. The connecting plate 21 corresponds to the first connecting hole 18, and the connecting member 20 passes through the middle of the connecting plate 21. That is, the connecting member 20 is screwed into the first connecting hole 18, the connecting plate 21 and the second connecting hole 19 in sequence, thereby further strengthening the fixation of the adjusted mating tool 3 on the drill bit 1, and further strengthening the connection and fixation effect between the insert post 4 and the mating tool 3.

[0042] Then reinsert the plug plate 16 into the plug slot 17, so that the lifting plate 22 can be housed in the mating tool 3, and the plug plate 16 can be reinstalled and fixed to the mating tool 3 (riveting method can be used).

[0043] The plug plate 16 is connected and fixed by a connecting plate and two connecting rods. The height of the connecting plate is greater than the height of the connecting rods. The height of the connecting plate makes the contact surface between the connecting plate and the plug slot 17 larger, which further ensures the stability of the plug and ensures that the mating tool 3 and the drill bit are tightly plugged in and will not move.

[0044] That is, the position of the mating tool 3 is adjusted and fixed by means of the plug plate 16, the first connecting hole 18, the second connecting hole 19 and the connector 20.

[0045] The insertion post 4 has a T-shaped cross-section. The drill bit 1 is fixedly connected to a sleeve 8 that is movably engaged with the insertion post 4. The sleeve 8 is connected to the threaded hole 7. The engagement between the sleeve 8 and the insertion post 4 ensures the smooth movement of the insertion post 4.

[0046] Instructions on how to adjust the threaded post 5 according to the mating tool 3:

[0047] The tool 3 is provided with a plug-in post 4. A threaded post 5 is fixedly connected to the end of the plug-in post 4. A threaded disc 6 is threadedly connected to the outer surface of the threaded post 5 and is threadedly connected to the drill bit 1. A control component is provided on the threaded disc 6 to control the rotation of the threaded disc 6. The control component can be slidably stored in the drill bit 1.

[0048] First, pull out the plunger 9. The control component includes a plunger 9 that is movably engaged with the threaded hole 7. Multiple limiting rods 10 that penetrate the threaded disc 6 are fixedly connected to the plunger 9. The plunger 9 is far away from the threaded hole 7, which facilitates a larger range of motion and makes it easier for the plunger 9 to rotate.

[0049] Then, rotate the control component to make the threaded disc 6 rotate and move along the threaded hole 7. The rotating threaded disc 6, under the restriction of the non-rotating threaded post 5, makes the threaded post 5 move (cannot rotate), that is, the threaded post 5 moves relative to the threaded disc 6 (making the distance the threaded post 5 moves greater than the distance the threaded disc 6 moves, which is convenient for insertion and fixing). This makes it easier for the moving insertion post 4 to adjust the position of the tool 3, and also increases the connection stability between the tool 3 and the drill bit 1. In addition, the threaded disc 6 has a locking effect on the threaded post 5, so that the threaded post 5 cannot rotate in the opposite direction.

[0050] Finally, the plunger 9 is inserted into the threaded hole 7 to seal the threaded hole 7;

[0051] Instructions for operating the control components to rotate the threaded disc 6:

[0052] The end of the threaded post 5 is fixedly connected to a pressing member 11. A pressing groove 12 is provided on one side of the plug post 9 to press against the pressing member 11. A cross groove 13 is provided on the other side of the plug post 9 to facilitate the rotation operation of the screwdriver.

[0053] When the plug 9 is inserted into the threaded hole 7, the end of the plug 4 is provided with an annular groove 14, and the end of the pressing member 11 is fixedly connected to a limiting plate 15 that presses against and fixes the annular groove 14. The limiting rod 10 drives the limiting plate 15 to move and insert into the annular groove 14. The contact surface between the end of the limiting plate 15 and the annular groove 14 is a rough surface (the contact surface may be a mutually cooperating anti-slip layer), thereby further ensuring that the plug 4 does not rotate, ensuring the connection stability between the threaded plate 6 and the plug 9, and preventing reverse rotation.

[0054] In this process, by rotating the plug 9, multiple limiting rods 10 are rotated, thereby causing the threaded disc 6 to rotate. Under the action of the threaded hole 7, the rotating threaded disc 6 moves simultaneously toward the mating tool 3.

[0055] The plunger 9 can be pulled out and moved, and the limiting rod 10 moves synchronously along the direction of the threaded disc 6. This does not affect the rotation of the limiting rod 10, which drives the rotation of the threaded disc 6, thus ensuring that the plunger 9 is outside the drill bit 1 for operation.

[0056] When the threaded disc 6 rotates and moves within the threaded hole 7, the insertion pin 4 and the threaded pin 5 move in the same direction but do not rotate, which is the same as the moving direction of the mating tool 3. Moreover, the moving efficiency of the insertion pin 4 and the threaded pin 5 is greater than that of the threaded disc 6. Furthermore, through the cooperation of the threaded disc 6 with the threaded rod and the threaded hole 7, reverse reset is effectively avoided (when the mating tool 3 is operating at high speed).

[0057] After the position adjustment is completed with the tool 3, the plug 9 is inserted into the threaded hole 7 (the depth to which it can be inserted is adjusted according to the position of the tool 3). The pressing part 11 is inserted into the pressing groove 12 to further restrict the plug 9 and prevent the plug 9 from rotating. The outer edge of the plug 9 is provided with a rubber layer to facilitate the stable insertion of the plug 9 into the threaded hole 7.

[0058] It is worth noting that the edge of the pressing member 11 is inclined, the side of the pressing groove 12 is inclined, the inclination angle of the edge of the pressing member 11 is greater than the inclination angle of the side of the pressing groove 12, and an anti-slip layer is provided at the edge of the pressing member 11, thereby further ensuring the snapping effect between the pressing member 11 and the pressing groove 12.

[0059] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
