Description

Technical Field

[0001] This invention belongs to the field of clutch gear processing technology, specifically a clutch inner disc tooth profile processing device and method. Background Technology

[0002] A clutch is a component located in the flywheel housing between the engine and the gearbox. It is used to cut off or transmit the power input from the engine to the gearbox, and to separate or engage the transmission system at any time. Common types include electromagnetic clutches and magnetic powder clutches.

[0003] Because the clutch can systematically separate and engage the power of a car, it plays an important role in the entire automotive system. The core of the clutch operates through gears, which require the gears to have good wear resistance.

[0004] In the existing technology, after long-term use and observation, it has been found that during the production of gears, the semi-finished gears need to be cut to a certain size. During the cutting process, the angle of the gears needs to be changed frequently. However, the fixing device in the existing technology requires special tools to change the angle of the gears, which is inconvenient to use.

[0005] Therefore, the present invention provides a device and method for machining the gear profile of the inner disc of a clutch. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a clutch inner disc tooth profile machining device and method.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A clutch inner disc gear profile machining device and method, comprising a base; a cutting device fixedly connected to the side wall of the base; a cutting table fixedly connected to the side wall of the base; the cutting device and the cutting table being correspondingly arranged; a fixing column fixedly connected to the side wall of the cutting table; a first sliding groove formed in the middle of the fixing column; a spring fixedly connected to the side wall of the first sliding groove; a sliding column slidably connected to the middle of the first sliding groove; the other end of the spring fixedly connected to the side wall of the sliding column; a pair of clamping plates intersecting the side wall of the sliding column; the clamping plates being mounted on the sliding column by torsion springs. On the side wall; a pair of No. 1 elastic telescopic rods are fixedly connected to the side wall of the fixed column; an arc-shaped rubber plate is fixedly connected to the side wall of the No. 1 elastic telescopic rod; this step, by providing a spring on the side wall of the sliding column, increases the clamping effect of the clamping plate and the cutting table on the gear during processing. By providing the No. 1 elastic telescopic rod, the effect of the arc-shaped rubber plate holding the gear is increased. In conjunction with the clamping plate, the fixing effect on the gear during processing is increased, reducing the possibility of the gear shaking or moving during processing, which could lead to deviations in cutting dimensions and the creation of defective products. At the same time, it facilitates the staff to change the gear angle.

[0008] Preferably, a first collection groove is installed on the side wall of the base; a second collection groove is installed on the side wall of the base; the first and second collection grooves are symmetrically arranged; a pair of limiting blocks are fixedly connected to the side wall of the first collection groove near the second collection groove; a pair of first limiting grooves are opened on the side wall of the second collection groove; the first limiting groove and the limiting block are correspondingly arranged; both the first limiting groove and the limiting block are T-shaped. This step, by providing the first and second collection grooves, increases the collection effect of cutting debris and residue, and improves the recycling effect of debris and residue. By providing the limiting block and the first limiting groove, and by providing the T-shaped limiting block and the first limiting groove, the fixing effect of installing the first and second collection grooves on the side wall of the base is increased, and the disassembly and cleaning of the first and second collection grooves are facilitated.

[0009] Preferably, one sidewall of the cutting table is inclined; a pair of second sliding grooves are formed on the sidewall of the cutting table; a sliding block is slidably connected to the middle of the second sliding groove; an elastic rope is fixedly connected to the sidewall of the sliding block; the other sidewall of the elastic rope is fixedly connected to the sidewall of the second sliding groove; a pair of scrapers are fixedly connected to the sidewall of the sliding block; a pull rope is fixedly connected to the end of the second sliding groove; a pair of second limiting grooves are formed on the sidewall of the cutting table; a pair of second elastic telescopic rods are fixedly connected to the sidewall of the base; the second elastic telescopic rods slide in the middle of the second limiting groove. The connection is made by fixing the other end of the pull rope to the end of the second elastic telescopic rod. This step reduces the accumulation of debris and residue on the side wall of the cutting table by using an inclined surface on one side wall of the cutting table. By providing the second elastic telescopic rod, the effect of pulling the sliding block and scraper to the side wall of the second sliding groove is increased during gear processing by using the pull rope. In addition, when used with the elastic rope, the scraping effect of the scraper on the side wall of the cutting table is increased when disassembling after gear processing is completed, which further improves the collection effect of the first collection groove and the second collection groove.

[0010] Preferably, the clamping plate has multiple sets of No. 3 limiting grooves on its side wall; a fixing rod is fixedly connected to the middle of the No. 3 limiting groove; a rotating cylinder is rotatably connected to the side wall of the fixing rod; this step, by providing a rotating cylinder, increases the smoothness of gear installation.

[0011] Preferably, a magnet is fixed to the side wall of the cutting table near the base; this step, by providing a magnet, increases the magnetic attraction effect on the gear during processing and reduces the possibility of gear shaking.

[0012] Preferably, a rubber pad is fixed to the side wall of the clamping plate away from the third limiting groove; this step increases the friction between the clamping plate and the cutting table when clamping the gear by providing a rubber pad.

[0013] Preferably, pull rings are fixed to the side walls of both the first and second collection tanks; the side walls of the pull rings are provided with anti-slip textures; this step increases the convenience of separating the first and second collection tanks by providing pull rings, and increases the friction on the side walls of the pull rings by providing anti-slip textures.

[0014] A method for machining the gear profile of the inner disc of a clutch, applicable to the aforementioned multi-channel data transfer device; the method includes:

[0015] S1: During gear installation, the operator uses a magnet to pull the sliding column. The spring on the side wall of the sliding column clamps the gear between the clamping plate and the cutting table. At the same time, the rubber pad on the side wall of the clamping plate contacts the gear to increase friction. The arc-shaped rubber plate on the side wall of the first elastic telescopic rod contacts the middle hole of the gear. The gear is clamped by the combined action of these actions. At this time, the gear on the side wall of the cutting table will be further fixed by the magnetic attraction of the magnet. The cutting device then cuts the edge of the gear on the side wall of the cutting table.

[0016] S2: The residue and debris generated by the cutting device at the edge of the gear will fall into the No. 1 collection tank and the No. 2 collection tank for collection. When it is necessary to disassemble the No. 1 collection tank and the No. 2 collection tank, pull the No. 1 collection tank and the No. 2 collection tank through the No. 1 limit groove and the limit block for installation and disassembly.

[0017] S3: The force of the gear's gravity and the spring on the side wall of the sliding column causing the clamping plate to contact the gear causes the second elastic telescopic rod to extend and retract. The copper drum magnet pulls the sliding block to move in the middle of the second sliding groove. After the cutting device completes the cutting of the gear edge, the sliding block scrapes and cleans the side wall of the cutting table.

[0018] S4: When the gear is installed and contacts the side wall of the clamping plate and the rotating drum, the rotating drum begins to rotate on the side wall of the fixed rod until the gear is installed on the side wall of the cutting table.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The clutch inner disc gear machining device and method of the present invention improves the clamping effect of the clamping plate and the cutting table on the gear during machining by providing a spring on the side wall of the sliding column, and improves the effect of the arc-shaped rubber plate holding the gear by providing a first elastic telescopic rod. In combination with the clamping plate, the fixing effect of the gear during machining is improved, reducing the possibility of the gear shaking or moving during machining, which would lead to deviation in cutting size and result in defective products. At the same time, it facilitates the operator to change the gear angle.

[0021] 2. The clutch inner disc tooth profile machining device and method of the present invention, by providing a first collection groove and a second collection groove, increases the collection effect of cutting debris and residue, and improves the recycling effect of debris and residue. By providing a limiting block and a first limiting groove, and by providing a limiting block and a first limiting groove, both of which are T-shaped, the fixing effect of installing the first collection groove and the second collection groove on the side wall of the base is improved, and the disassembly and cleaning of the first collection groove and the second collection groove are facilitated.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 , Figure 2 and Figure 5As shown in the embodiment of the present invention, a clutch inner disc gear profile machining device and method includes a base 1; a cutting device 11 is fixedly connected to the side wall of the base 1; a cutting table 12 is fixedly connected to the side wall of the base 1; the cutting device 11 and the cutting table 12 are correspondingly arranged; a fixing column 13 is fixedly connected to the side wall of the cutting table 12; a first sliding groove 14 is formed in the middle of the fixing column 13; a spring is fixedly connected to the side wall of the first sliding groove 14; a sliding column 15 is slidably connected to the middle of the first sliding groove 14; the other end of the spring is fixedly connected to the side wall of the sliding column 15; the sliding column 15 is slidably connected to the side wall of the sliding column 15; the spring 13 is fixedly ... A pair of clamping plates 16 are connected to the side wall of the moving column 15; the clamping plates 16 are mounted on the side wall of the sliding column 15 by torsion springs; a pair of first elastic telescopic rods 17 are fixedly connected to the side wall of the fixed column 13; an arc-shaped rubber plate 18 is fixedly connected to the side wall of the first elastic telescopic rod 17; when the gear is being processed, the middle hole of the gear is aligned with the sliding column 15, so that the gear contacts the side wall of the clamping plate 16. At this time, pressing the gear causes the clamping plate 16 to rotate on the side wall of the sliding column 15, thereby pulling the sliding column 15, so that the sliding column 15 is in the first sliding groove 14. Slide the gear along the cutting table 12, then press the first elastic telescopic rod 17 to extend or retract it, placing the gear on the side wall of the cutting table 12. Then release the sliding column 15 and the first elastic telescopic rod 17. The arc-shaped rubber plate 18 will then fit against the side wall of the gear's central hole, and the spring on the side wall of the sliding column 15 will cause the clamping plate 16 and the cutting table 12 to clamp the gear. When it is necessary to change the gear's angle, pull the sliding column 15 or push the arc-shaped rubber plate 18 until a gap appears between the clamping plate 16 and the cutting table 12, and a gap appears between the arc-shaped rubber plate 18 and the side wall of the gear. The gear is rotated to change its angle. This step is enhanced by the spring on the side wall of the sliding column 15, which increases the clamping effect of the clamping plate 16 and the cutting table 12 on the gear during processing. The first elastic telescopic rod 17 enhances the effect of the arc-shaped rubber plate 18 in holding the gear in place. Together with the clamping plate 16, the gear is fixed during processing, reducing the possibility of the gear shaking or moving during processing, which could lead to deviations in the cutting dimensions and defective products. At the same time, it makes it easier for the operator to change the gear angle.

[0032] like Figure 1As shown, a first collection groove 2 is installed on the side wall of the base 1; a second collection groove 21 is installed on the side wall of the base 1; the first collection groove 2 and the second collection groove 21 are symmetrically arranged; a pair of limiting blocks 22 are fixedly connected to the side wall of the first collection groove 2 near the second collection groove 21; a pair of first limiting grooves 23 are opened on the side wall of the second collection groove 21; the first limiting grooves 23 and the limiting blocks 22 are correspondingly arranged; the first limiting grooves 23 and the limiting blocks 22 are both T-shaped; when the cutting device 11 cuts the gear on the side wall of the cutting table 12, the cutting debris and residue will fall into the first collection groove 2 and the second collection groove 21. When it is necessary to clean the inside of the first collection groove 2 and the second collection groove 21... When cleaning up residue and garbage, lift either the first collection trough 2 or the second collection trough 21, so that the limiting block 22 on the side wall of the first collection trough 2 slides in the middle of the first limiting groove 23 until the limiting block 22 leaves the middle of the first limiting groove 23. This step, by providing the first collection trough 2 and the second collection trough 21, increases the collection effect of cutting debris and residue, and improves the recycling effect of residue and debris. By providing the limiting block 22 and the first limiting groove 23, and by providing the T-shaped limiting block 22 and the first limiting groove 23, the fixing effect of installing the first collection trough 2 and the second collection trough 21 on the side wall of the base 1 is increased, and the disassembly and cleaning of the first collection trough 2 and the second collection trough 21 are facilitated.

[0033] like Figure 3As shown, one sidewall of the cutting table 12 is inclined; a pair of second sliding grooves 3 are formed on the sidewall of the cutting table 12; a sliding block 32 is slidably connected to the middle of the second sliding groove 3; an elastic rope 31 is fixedly connected to the sidewall of the sliding block 32; the other sidewall of the elastic rope 31 is fixedly connected to the sidewall of the second sliding groove 3; a pair of scrapers 33 are fixedly connected to the sidewall of the sliding block 32; a pull rope 35 is fixedly connected to the end of the second sliding groove 3; a pair of second limiting grooves 34 are formed on the sidewall of the cutting table 12; a pair of second elastic telescopic rods 36 are fixedly connected to the sidewall of the base 1; The second elastic telescopic rod 36 is slidably connected in the middle of the second limiting groove 34; the other end of the pull rope 35 is fixed to the end of the second elastic telescopic rod 36; when the gear is placed on the side wall of the cutting table 12, it is clamped by the clamping plate 16 and the cutting table 12, the gear contacts the side wall of the second elastic telescopic rod 36, and slides and extends in the middle of the second limiting groove 34. At this time, through the pull rope 35, the extension and retraction of the second elastic telescopic rod 36 will pull the sliding block 32 to slide in the middle of the second sliding groove 3 until it slides to the other end, and the gear is placed on the cutting table 12. Cutting is performed on the side wall of the cutting table 12, and the elastic rope 31 lengthens. The debris and residue generated from cutting slide along the inclined side wall of the cutting table 12 into the first collection tank 2 and the second collection tank 21. When the gear is removed after cutting, the second elastic telescopic rod 36 slides again, and the elastic rope 31 pulls the sliding block 32 to slide again in the middle of the second sliding tank 3. The scraper 33 on the side wall of the sliding block 32 scrapes the inclined side wall of the cutting table 12, scraping the residue and debris attached to the side wall of the cutting table 12 into the first collection tank 2. Inside the second collection trough 21, this step reduces the accumulation of debris and residue on the side wall of the cutting table 12 by using a sloped side wall. The second elastic telescopic rod 36 increases the effect of pulling the sliding block 32 and scraper 33 to the side wall of the second sliding trough 3 by pulling the rope 35 during gear processing. In addition, when used with the elastic rope 31, it increases the scraping effect of the scraper 33 on the side wall of the cutting table 12 when disassembling after gear processing, further improving the collection effect of the first collection trough 2 and the second collection trough 21.

[0034] like Figure 5 As shown, the clamping plate 16 has multiple sets of No. 3 limiting grooves 4 on its side wall; a fixing rod 41 is fixedly connected to the middle of the No. 3 limiting groove 4; a rotating cylinder 42 is rotatably connected to the side wall of the fixing rod 41; when the gear first contacts the side wall of the clamping plate 16 during installation, it is affected by the torsion spring on the side wall of the clamping plate 16, and the gear contacts the side wall of the rotating cylinder 42 on the side wall of the fixing rod 41. As the gear is installed, the rotating cylinder 42 rotates on the side wall of the fixing rod 41. This step, by providing the rotating cylinder 42, increases the smoothness of the gear during installation.

[0035] like Figure 4As shown, a magnet 5 is fixed to the side wall of the cutting table 12 near the base 1. When the gear is cutting on the side wall of the cutting table 12, the magnet 5 will always have a magnetic attraction effect on the side wall of the gear. This step increases the magnetic attraction effect on the gear during processing by providing the magnet 5, and reduces the situation of gear shaking.

[0036] like Figure 5 As shown, a rubber pad 6 is fixed to the side wall of the clamping plate 16 away from the third limiting groove 4; when the clamping plate 16 and the cutting table 12 clamp the gear, the rubber pad 6 contacts the side wall of the gear. This step increases the friction when the clamping plate 16 and the cutting table 12 clamp the gear by providing the rubber pad 6.

[0037] like Figure 2 As shown, pull rings 7 are fixed to the side walls of both the first collection tank 2 and the second collection tank 21; the side walls of the pull rings 7 are provided with anti-slip textures 71; when it is necessary to disassemble the first collection tank 2 and the second collection tank 21, the worker pulls the pull rings 7, which causes the limiting block 22 on the side wall of the first collection tank 2 to slide in the middle of the first limiting groove 23. This step, by providing pull rings 7, increases the convenience of separating the first collection tank 2 and the second collection tank 21, and by providing anti-slip textures 71, increases the friction on the side walls of the pull rings 7.

[0038] like Figure 5 As shown, the sliding column 15 has a pair of No. 4 limiting grooves 8 on its side wall; when the staff needs to pull the sliding column 15, the staff will clamp their fingers into the No. 4 limiting groove 8 and then pull the sliding column 15. This step increases the convenience of the staff when pulling the sliding column 15 by providing the No. 4 limiting groove 8.

[0039] A method for machining the gear profile of the inner disc of a clutch, applicable to the aforementioned multi-channel data transfer device; the method includes:

[0040] S1: During gear installation, the operator uses magnet 5 to pull sliding column 15. The spring on the side wall of sliding column 15 clamps the gear between clamping plate 16 and cutting table 12. At the same time, rubber pad 6 on the side wall of clamping plate 16 contacts the gear to increase friction. The arc-shaped rubber plate 18 on the side wall of elastic telescopic rod 17 contacts the middle hole of the gear. The gear is clamped by the cooperation of these parts. At this time, the gear on the side wall of cutting table 12 will be further fixed by the magnetic attraction of magnet 5. The cutting device 11 cuts the edge of the gear on the side wall of cutting table 12.

[0041] S2: The residue and debris generated by the cutting device 11 when cutting the edge of the gear will fall into the first collection tank 2 and the second collection tank 21 for collection. When it is necessary to disassemble the first collection tank 2 and the second collection tank 21, the first collection tank 2 and the second collection tank 21 are pulled by the pull ring 7, and the first collection tank 2 and the second collection tank 21 are installed and disassembled through the first limiting groove 23 and the limiting block 22.

[0042] S3: The force of the gear's gravity and the spring on the side wall of the sliding column 15 causing the clamping plate 16 to contact the gear causes the second elastic telescopic rod 36 to extend and retract, and the copper drum magnet 5 pulls the sliding block 32 to move in the middle of the second sliding groove 3. After the cutting device 11 completes the cutting of the gear edge, the sliding block 32 scrapes and cleans the side wall of the cutting table 12.

[0043] S4: When the gear is installed and contacts the side wall of the clamping plate 16 and the rotating drum 42, the rotating drum 42 begins to rotate on the side wall of the fixed rod 41 until the gear is installed on the side wall of the cutting table 12.

[0044] Working principle: When the gear is being processed, the middle hole of the gear is aligned with the sliding post 15, causing the gear to contact the side wall of the clamping plate 16. Pressing the gear causes the clamping plate 16 to rotate on the side wall of the sliding post 15, pulling the sliding post 15 and causing it to slide in the middle of the first sliding groove 14. Then, pressing the first elastic telescopic rod 17 causes it to extend and retract, placing the gear on the side wall of the cutting table 12. Releasing the sliding post 15 and the first elastic telescopic rod 17 allows the arc-shaped rubber plate 18 to fit against the side wall of the gear's middle hole, and the spring on the side wall of the sliding post 15 clamps the gear between the clamping plate 16 and the cutting table 12. When the gear angle needs to be changed, the sliding post is pulled... 15. Alternatively, push the arc-shaped rubber plate 18 until a gap appears between the clamping plate 16 and the cutting table 12, and a gap appears between the arc-shaped rubber plate 18 and the gear sidewall. Rotate the gear to change its angle. When the cutting device 11 cuts the gear on the sidewall of the cutting table 12, the cutting debris and residue will fall into the first collection tank 2 and the second collection tank 21. When it is necessary to clean the residue and debris inside the first collection tank 2 and the second collection tank 21, lift the first collection tank 2 or lift the second collection tank 21, so that the limiting block 22 on the sidewall of the first collection tank 2 slides in the middle of the first limiting groove 23 until the limiting block 22 leaves the middle of the first limiting groove 23. When the gear is placed on the sidewall of the cutting table 12, it is held by the clamping plate 16. The gear is clamped by the cutting table 12, and the gear contacts the side wall of the second elastic telescopic rod 36. It slides and extends in the middle of the second limiting groove 34. At this time, the extension and retraction of the second elastic telescopic rod 36 through the pull rope 35 will pull the sliding block 32 to slide in the middle of the second sliding groove 3 until it slides to the other end. The gear is placed on the side wall of the cutting table 12 for cutting, and the elastic rope 31 becomes longer. The debris and residue generated by cutting will slide along the inclined side wall of the cutting table 12 into the first collection groove 2 and the second collection groove 21. When the cutting is completed and the gear is removed, the second elastic telescopic rod 36 slides again, and the elastic rope 31 will pull the sliding block 32 to slide again in the middle of the second sliding groove 3, and the side wall of the sliding block 32... The scraper 33 scrapes the inclined side wall of the cutting table 12, scraping the residue and debris attached to the side wall of the cutting table 12 into the first collection tank 2 and the second collection tank 21. When the gear first contacts the side wall of the clamping plate 16 during installation, it is affected by the torsion spring on the side wall of the clamping plate 16, and the gear contacts the side wall of the rotating cylinder 42 on the side wall of the fixing rod 41. As the gear is installed, the rotating cylinder 42 rotates on the side wall of the fixing rod 41. When the gear cuts on the side wall of the cutting table 12, the magnet 5 will always have a magnetic attraction effect on the side wall of the gear. When the clamping plate 16 and the cutting table 12 clamp the gear, the rubber pad 6 contacts the side wall of the gear. When it is necessary to disassemble the first collection tank 2 and the second collection tank 21, the operator pulls the pull ring 7.This, in turn, causes the limiting block 22 on the side wall of the first collection tank 2 to slide in the middle of the first limiting groove 23.

5. A device for machining the profile of the teeth of a clutch inner plate according to claim 4, characterized in that: A rubber pad (6) is fixed to the side wall of the clamping plate (16) away from the third limiting groove (4).

6. A device for machining the profile of the teeth of a clutch inner plate according to claim 5, characterized in that: Both the first collection tank (2) and the second collection tank (21) have pull rings (7) fixedly connected to their side walls; the pull rings (7) have anti-slip textures (71) on their side walls.

7. A method of profile machining of a disc spline in a clutch, characterized by: This method is applicable to a clutch inner disc gear machining device according to any one of claims 1-6; the method includes: S1: when the gear is installed, the worker pulls the sliding column (15) through the magnet (5), and the spring on the side wall of the sliding column (15) makes the clamping plate (16) clamp the gear between the cutting table (12), at the same time the rubber pad (6) on the side wall of the clamping plate (16) contacts the gear to increase the friction, and the arc-shaped rubber plate (18) on the side wall of the first elastic telescopic rod (17) partially contacts the middle hole of the gear, which are used together to clamp the gear. At this time, the gear on the side wall of the cutting table (12) will be magnetically attracted by the magnet (5) for further fixation, and the cutting device (11) will cut the edge of the gear on the side wall of the cutting table (12); S2: the residue and debris generated by the cutting device (11) when cutting the edge of the gear will fall into the first and second collecting grooves (2) and (21) for collection. When the first and second collecting grooves (2) and (21) need to be disassembled, the first and second collecting grooves (2) and (21) are pulled through the pull ring (7), and the first and second collecting grooves (2) and (21) are installed and disassembled through the first limiting groove (23) and the limiting block (22); S3: the force of the gear's gravity and the spring on the side wall of the sliding column (15) driving the clamping plate (16) to contact the gear makes the second elastic telescopic rod (36) extend and retract, and the copper drum magnet (5) pulls the sliding block (32) to move in the middle of the second sliding groove (3). After the cutting device (11) completes the cutting of the edge of the gear, the sliding block (32) scrapes and cleans the side wall of the cutting table (12); S4: when the gear is installed and the clamping plate (16) contacts the side wall, and contacts the rotating drum (42), the rotating drum (42) starts to rotate on the side wall of the fixed rod (41) until the gear is installed on the side wall of the cutting table (12).
