Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically a positioning device for a motorcycle clutch pressure plate. Background Technology

[0002] The clutch pressure plate is a key component of the motorcycle clutch system. It is typically a metal disc with multiple structures for mounting springs or diaphragm springs, as well as friction surfaces that mate with the clutch driven plate. Located on the engine flywheel side, it is tightly connected to the flywheel and, with the clutch cover, is fixed to it by bolts and other connecting components. Together with the clutch driven plate and clutch discs, it forms the clutch assembly. When the driver squeezes the clutch lever, the force transmitted through the clutch cable or hydraulic system causes the pressure plate to move backward against the spring pressure, thus releasing the clamping force on the clutch driven plate. At this time, engine power cannot be transmitted to the transmission, achieving power cut-off and facilitating gear shifting. When the clutch lever is released, the pressure plate moves forward under the spring force, tightly pressing against the clutch driven plate. This allows power transmission between the engine flywheel, pressure plate, and driven plate through friction, transferring engine power to the transmission and driving the motorcycle. The machining of the pressure plate involves multiple processes, each requiring positioning and clamping devices to ensure the dimensional and positional accuracy of each component. Based on the above, the inventors have discovered the following problems: In actual use, the current positioning device requires manual replacement of positioning components that match the size of the motorcycle clutch pressure plate when processing pressure plates of different sizes. This is cumbersome, time-consuming, and labor-intensive, as the manual operation inevitably introduces errors that may lead to inaccurate positioning and affect the processing quality of the pressure plate, such as drilling position deviations and uneven grinding.

[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a motorcycle clutch pressure plate positioning device in order to achieve a more practical purpose. Utility Model Content

[0004] The purpose of this invention is to provide a motorcycle clutch pressure plate positioning device to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A motorcycle clutch pressure plate positioning device includes a drive assembly, a positioning assembly, and a support assembly. The positioning assembly is positioned above the drive assembly, and the support assembly is positioned outside the positioning assembly. The drive assembly drives the positioning assembly to rotate. The positioning assembly is used to position and clamp pressure plates of different sizes. The support assembly is used to support and fix the bottom of the pressure plate. The positioning assembly includes a turntable with an opening at its center. A cylinder is installed inside the opening, and a round seat is installed at the top of the cylinder. The round seat has several sliding grooves inside and a round hole at its center. The sliding grooves and the round hole are interconnected. A slider is slidably connected inside each of the sliding grooves. A disc is located inside the round hole. Several grooves are formed on the outer wall of the disc. A rotating shaft is rotatably connected inside each of the grooves. A pair of connecting rods are sleeved on the outside of the rotating shaft. A connecting seat is hinged between the ends of the pair of connecting rods away from the rotating shaft. One side of the connecting seat is fixedly connected to one side of the slider. Furthermore, the number of both the sliding groove and the slider is six. Each slider has a contact block mounted on its side opposite the connecting seat, and one side of the outer wall of the contact block is clearance-fitted with the inner wall of the central shaft hole of the pressure plate. The advantage of this further solution is that by setting contact blocks, the number of contact blocks is the same as the number of sliders, and the outer wall of the contact block fits with the inner wall of the central shaft hole of the pressure plate. When the six sliders change from a retracted state to an expanded state, the contact blocks abut against the inner wall of the central shaft hole of the pressure plate, thereby fixing the pressure plate for subsequent processing.

[0007] Furthermore, the disc has six through holes inside, and each of the six through holes has a smooth rod inside. Both ends of the smooth rod are fixedly connected to the inner wall of the hole, and the outer wall of the smooth rod slides in contact with the inner wall of the through hole. A cylinder is bolted to the bottom of the insert, and a piston rod is connected to the output end of the cylinder. The piston rod extends through the insert and the circular base into the interior of the circular base at the end furthest from the cylinder, and is fixedly connected to the bottom of the disc at the end furthest from the cylinder. The beneficial effect of this further solution is that, through the combined use of the cylinder and piston rod, since the end of the piston rod furthest from the cylinder is fixed to the bottom of the disc, when the cylinder is activated, its output end pushes the piston rod upward, thereby pushing the disc upward within the circular hole. During this upward movement, the outer wall of the smooth rod slides in contact with the inner wall of the through hole, thus ensuring stable movement of the disc under the action of the six smooth rods.

[0008] Furthermore, the support assembly includes a support platform, which is sleeved on the outside of the insert. The inner wall of the support platform is fixedly connected to the outer wall of the insert, and the bottom end of the support platform is fixedly connected to the top end of the turntable. A support ring is installed on the top end of the support platform, and the inner wall of the support ring is fixedly connected to the outer wall of the insert. The beneficial effect of this further solution is that, through the cooperative use of the support platform and support ring, when the shaft hole at the center of the pressure plate body is aligned with the round seat and pressed down, the bottom surface of the pressure plate body contacts the support ring, allowing the support ring and support platform to provide stable support for the pressure plate body.

[0009] Furthermore, the support ring has an internal cavity, and its top surface has several mounting holes. Each mounting hole contains a vacuum suction cup, and the bottom end of each vacuum suction cup is connected to a negative pressure tube. The negative pressure tube is connected to the vacuum suction cup, and its end away from the vacuum suction cup is located inside the cavity. The support ring has a mounting base on its front side, and the mounting base has a mounting groove inside. A vacuum pump is installed inside the mounting groove, and the input end of the vacuum pump passes through the mounting base and the support ring, extending into the interior of the support ring.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the vacuum pump, negative pressure tube, and vacuum suction cups, when the pressure plate body contacts several vacuum suction cups on the top surface of the support ring, the pressure plate body adheres to the upper end of the vacuum suction cups due to gravity. At this time, the cavity between the bottom end of the pressure plate body and the upper end of the vacuum suction cups is under normal pressure. Through the negative pressure tube, one end of the negative pressure tube is connected to the vacuum suction cup, and the other end is located in the cavity. The input end of the vacuum pump is also located in the cavity, thus connecting the vacuum suction cups and the vacuum pump. When the vacuum pump starts, it causes the pressure plate body to... The cavity between the bottom of the pressure plate and the top of the vacuum suction cup is evacuated to a vacuum. At this time, there is a pressure difference between the external and internal air pressure of the vacuum suction cup, which makes the cavity between the bottom of the pressure plate and the top of the vacuum suction cup negative pressure. This enables the vacuum suction cup to adsorb the pressure plate, thereby further assisting in the positioning of the pressure plate. The adsorption and release working principle of the vacuum pump, vacuum suction cup and negative pressure tube is common knowledge. For example, Chinese Patent No. CN220162742U discloses a permanent magnet ferrite forming device.

[0011] Furthermore, the drive assembly includes a base, the top surface of which has a circular groove, and the interior of the base, below the circular groove, has a slot, which is connected to the circular groove. The turntable and the insert are respectively disposed inside the circular groove and the slot, and the outer wall of the turntable is connected to the inner wall of the circular groove by a bearing.

[0012] Furthermore, the base has an installation cavity located directly below the slot. The bottom of the installation cavity is connected to a motor mount by bolts. A servo motor is installed on the top of the motor mount, and the output end of the servo motor is fixedly connected to the bottom of the insert.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by setting a servo motor, when the servo motor is working, it is convenient for the insert to rotate inside the slot. Since the insert is installed inside the opening in the center of the turntable, when the insert rotates, the turntable rotates inside the circular groove, thereby realizing the rotation of the pressure plate body positioned on the support component. This allows the operator to use polishing or drilling equipment to process the pressure plate body. The rotatability of the pressure plate body means that the operator does not need to frequently adjust the processing position. They can simply rotate the pressure plate body to process different parts of it.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This motorcycle clutch pressure plate positioning device aligns the central shaft hole of the pressure plate body to be processed with the round seat and then presses it down. At this time, the bottom surface of the pressure plate body contacts the support ring, so that the support ring and the support platform can provide stable support force for the pressure plate body. When the cylinder is started, its output end pushes the piston rod upward, thereby pushing the disc upward inside the round hole. Due to the sliding fit between the outer wall of the smooth rod and the inner wall of the through hole, the disc moves upward stably under the action of the six smooth rods. Since the outer wall of the disc has six grooves, the rotating shaft is rotatably connected in the grooves, and a pair of connecting rods are sleeved on the outside of the rotating shaft. One end of the pair of connecting rods is hinged to the connecting seat, and the connecting seat is fixed to the slider. During the upward movement, the six sliders move outward under the action of the connecting rods, and the contact block abuts against the inner wall of the central shaft hole of the pressure plate, thereby fixing the pressure plate to facilitate subsequent processing operations.

The drive assembly 1 is used to drive the positioning assembly 2 to rotate. The positioning assembly 2 is used to position and clamp pressure plates of different sizes. The support assembly 3 is used to support and fix the bottom of the pressure plate. The positioning assembly 2 includes a turntable 21, with an opening at the center of the turntable 21. A cylinder 22 is installed inside the opening, and a circular seat 23 is installed at the top of the cylinder 22. The circular seat 23 has several sliding grooves inside, and a circular hole is opened at the center of the circular seat 23. The several sliding grooves and the circular hole are connected to the circular hole. The holes are interconnected. Each of the several grooves has a sliding block 24 slidably connected inside. A disc 27 is located inside the circular hole. The outer wall of the disc 27 has several grooves, each of which is rotatably connected to a rotating shaft 28. A pair of connecting rods 29 are sleeved on the outside of the rotating shaft 28. A connecting seat 210 is hinged between the ends of the connecting rods 29 away from the rotating shaft 28.

Each of the six through holes is equipped with a smooth rod 26. Both ends of the smooth rod 26 are fixedly connected to the inner wall of the circular hole, and the outer wall of the smooth rod 26 slides against the inner wall of the through hole. A cylinder 211 is bolted to the bottom of the insert 22. A piston rod is connected to the output end of the cylinder 211. The piston rod extends through the insert 22 and the circular seat 23 at the end furthest from the cylinder 211, reaching the interior of the circular seat 23. The piston rod is also fixedly connected to the bottom of the disc 27 at the end furthest from the cylinder 211. The appearance of the motorcycle clutch pressure plate is similar to that disclosed in Chinese Patent Publication No. CN201507574U. After aligning the central shaft hole of the pressure plate body to be processed with the circular seat 23, it is pressed down to activate... When the cylinder 211 is activated, its output end pushes the piston rod upward, thereby pushing the disc 27 upward inside the circular hole. Due to the sliding fit between the outer wall of the smooth rod 26 and the inner wall of the through hole, the disc 27 moves upward stably under the action of the six smooth rods 26. Since the outer wall of the disc 27 has six grooves, the rotating shaft 28 is rotatably connected in the grooves, and a pair of connecting rods 29 are sleeved on the outside of the rotating shaft 28. One end of the pair of connecting rods 29 is hinged to the connecting seat 210, and the connecting seat 210 is fixed to the slider 24. During the upward movement, the six sliders 24 make outward expansion movement under the action of the connecting rods 29, and the contact block 25 abuts against the inner wall of the central shaft hole of the pressure plate, thereby fixing the pressure plate for subsequent processing.

[0024] 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.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: The support assembly 3 includes a support platform 31, which is sleeved on the outside of the insert 22. The inner wall of the support platform 31 is fixedly connected to the outer wall of the insert 22. The bottom end of the support platform 31 is fixedly connected to the top end of the turntable 21. A support ring 32 is installed on the top end of the support platform 31. The inner wall of the support ring 32 is fixedly connected to the outer wall of the insert 22. A cavity is opened inside the support ring 32. A plurality of mounting holes 33 are opened on the top surface of the support ring 32. Vacuum suction cups 34 are installed inside each of the mounting holes 33. A negative pressure pipe 35 is connected to the bottom end of each of the vacuum suction cups 34. The negative pressure pipe 35 is connected to the vacuum suction cups 34. The end of the negative pressure pipe 35 away from the vacuum suction cups 34 is located inside the cavity. A mounting seat is installed on the front side of the support ring 32. A mounting groove is opened inside the mounting seat. A vacuum pump 36 is installed inside the mounting groove. The input of the vacuum pump 36 is... The end of the tube passes through the mounting base and the support ring 32 and extends into the interior of the support ring 32. When the pressure plate body contacts the several vacuum suction cups 34 on the top surface of the support ring 32, the pressure plate body adheres to the upper end of the vacuum suction cups 34 due to gravity. At this time, the cavity between the bottom end of the pressure plate body and the upper end of the vacuum suction cup 34 is under normal pressure.

At this time, there is a pressure difference between the external air pressure and the internal air pressure of the vacuum suction cup 34, so that the cavity between the bottom end of the pressure plate body and the upper end of the vacuum suction cup 34 is under negative pressure, thereby realizing the adsorption of the pressure plate body by the vacuum suction cup 34, and further assisting in the positioning of the pressure plate body.

[0026] 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.

[0027] Please see Figures 1-6The present invention provides a technical solution: the drive assembly 1 includes a base 11, a circular groove 14 is formed on the top surface of the base 11, and a slot 15 is formed inside the base 11 below the circular groove 14, the slot 15 and the circular groove 14 are interconnected, a turntable 21 and a plug 22 are respectively disposed inside the circular groove 14 and the slot 15, the outer wall of the turntable 21 is connected to the inner wall of the circular groove 14 by a bearing, and an installation cavity is formed inside the base 11 directly below the slot 15, a motor base 12 is bolted to the bottom of the installation cavity, a servo motor 13 is mounted on the top of the motor base 12, and the output end of the servo motor 13 is fixedly connected to the bottom end of the plug 22. When the servo motor 13 is working, it facilitates the rotation of the insert 22 inside the slot 15. Since the insert 22 is installed inside the opening in the center of the turntable 21, when the insert 22 rotates, the turntable 21 rotates inside the circular groove 14, thereby realizing the rotation of the pressure plate body positioned on the support component 3. This allows the operator to use a handheld angle grinder or electric drill to process the pressure plate body. The angle grinder and electric drill are Dongcheng DCSM04-100E and Shengbang K6166 handheld engineering drills, respectively. The rotatability of the pressure plate body means that the operator does not need to frequently adjust the processing position. They can simply rotate the pressure plate body to process different parts of it.Specifically, the working principle of this motorcycle clutch pressure plate positioning device is as follows: During use, the central shaft hole of the pressure plate body to be processed is aligned with the round seat 23 and then pressed down. At this time, the bottom surface of the pressure plate body contacts the support ring 32, allowing the support ring 32 and the support platform 31 to provide stable support for the pressure plate body. When the starting cylinder 211 is activated, its output end pushes the piston rod upward, thereby pushing the disc 27 upward inside the round hole. Due to the sliding fit between the outer wall of the polished rod 26 and the inner wall of the through hole, the disc 27 moves stably upward under the action of the six polished rods 26. Six grooves are formed in the wall, and a rotating shaft 28 is rotatably connected in the grooves. A pair of connecting rods 29 are sleeved on the outside of the rotating shaft 28. A connecting seat 210 is hinged between one end of the pair of connecting rods 29. The connecting seat 210 is fixed to the slider 24. During the upward movement, the six sliders 24 move outward under the action of the connecting rods 29. The contact block 25 abuts against the inner wall of the central shaft hole of the pressure plate, thereby fixing the pressure plate for subsequent processing. When the pressure plate body contacts the vacuum suction cups 34 on the top surface of the support ring 32, the pressure plate body adheres to the upper end of the vacuum suction cups 34 due to gravity. At this time, the bottom of the pressure plate body... The cavity between the bottom of the pressure plate and the upper end of the vacuum suction cup 34 is under normal pressure. A negative pressure pipe 35 connects the vacuum suction cup 34 at one end and is located inside the cavity at the other end. The vacuum pump's input end is also located inside the cavity, connecting the vacuum suction cup 34 and the vacuum pump 36. When the vacuum pump 36 starts, it evacuates the cavity between the bottom of the pressure plate and the upper end of the vacuum suction cup 34 to a vacuum. At this time, a pressure difference exists between the external and internal air pressures of the vacuum suction cup 34, creating a negative pressure state in the cavity between the bottom of the pressure plate and the upper end of the vacuum suction cup 34. This allows the vacuum suction cup 34 to adhere to the pressure plate, thus achieving... The first step is to assist in positioning the pressure plate body. When the servo motor 13 is working, it facilitates the rotation of the insert 22 inside the slot 15. Since the insert 22 is installed inside the opening in the center of the turntable 21, when the insert 22 rotates, the turntable 21 rotates inside the circular groove 14, thereby realizing the rotation of the pressure plate body positioned on the support component 3. This allows the operator to use polishing or drilling equipment to process the pressure plate body. The rotatability of the pressure plate body means that the operator does not need to frequently adjust the processing position. They can simply rotate the pressure plate body to process different parts of it.
