Description

Technical Field

[0001] This invention relates to the field of transmission technology, specifically to a transmission device with a linear transmission mechanism. Background Technology

[0002] A transmission device, also known as a drive mechanism, is a mechanical device used to transmit power and motion, playing a crucial role in various mechanical equipment. A transmission device changes the direction of power transmission; for example, it can change rotational motion from one direction to another, thus transporting materials from one end to the other, replacing manual labor. With rapid societal progress and the development of the machinery industry, the application of linear drives is increasing. Linear drives offer high precision, high efficiency, and ease of control; therefore, they are increasingly used in production and daily life. Linear drives accelerate production and bring convenience to daily life.

[0003] Currently, traditional transmissions often experience jamming during operation, resulting in insufficient transmission smoothness and vibration. This hinders the straight-line conveying of materials, affects overall operating efficiency, and makes subsequent use inconvenient. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A transmission device with a linear transmission mechanism includes:

[0006] The outer casing, and guide holes opened at the middle of the top and bottom of the outer casing; a strip-shaped hole is opened on the side of the top of the outer casing.

[0007] A drive mechanism for linear transmission is mounted in the middle of the housing.

[0008] The drive mechanism includes a servo motor and a lead screw. The servo motor is fixedly mounted on the side of the outer casing. The two ends of the lead screw are rotatably mounted between the inner wall of the outer casing. The output end of the servo motor is fixedly mounted to the lead screw via a coupling. A sliding sleeve is mounted on the surface of the lead screw, and the lead screw passes through the center of the sliding sleeve. I-shaped rollers are rotatably mounted on the top and bottom of the outer circular surface of the sliding sleeve, and the I-shaped rollers are rolled between the rollers and guide holes. An annular ring is fixedly mounted on the end face of the sliding sleeve. Ball bearings are rolled on the inner wall of the sliding sleeve, and the spherical surface of the ball bearings interacts with the lead screw. The sliding sleeve is mounted on a T-shaped platform fixedly on the top of its outer circular surface, with an oil hole at the bottom of the annular ring located directly below the ball bearing. The sleeve is mounted in the middle of the housing via a lead screw. The rotation of the servo motor output drives the lead screw to rotate, and the ball bearing rolls within the helical grooves on the lead screw surface. The rotation of the lead screw applies a pushing force to the ball bearing, which is then transmitted to the sliding sleeve via its rolling motion. Combined with the interaction between the guide hole and the T-shaped platform, the sliding sleeve and the T-shaped platform achieve linear transmission.

[0009] Preferably, the lead screw is installed horizontally, the servo motor is installed at the same height as the lead screw, and there are four I-shaped rollers, with the positions of the four I-shaped rollers corresponding to the positions of the guide holes.

[0010] By moving the sliding sleeve and the T-shaped platform in a straight line together, and by using the I-shaped rollers installed at the guide hole, the I-shaped rollers can roll to support the sliding sleeve, making the sliding sleeve move more smoothly and less prone to shaking.

[0011] Preferably, the lead screw passes through the center of the annular ring, the annular ring is made of rubber, there are two annular rings, and the two annular rings are symmetrically installed along the sliding sleeve.

[0012] By using a lead screw to pass through the center of the annular ring, and the annular ring moving linearly together with the sliding sleeve, the gap between the center hole of the sliding sleeve and the surface of the lead screw can be covered by the annular ring, reducing the entry of dust and impurities into the interior of the sliding sleeve, thus achieving a protective effect.

[0013] Preferably, the balls are evenly installed on the inner wall of the sliding sleeve, and the spherical surface of the balls fits into the helical groove on the surface of the lead screw.

[0014] As the lubricating oil is applied to the spiral grooves on the surface of the lead screw, and the ring is made of rubber, the ring itself is flexible and makes flexible contact with the surface of the lead screw, so as not to scratch the surface of the lead screw. Furthermore, by using the sliding sleeve to drive the ring to move linearly, the lubricating oil adhering to the surface of the lead screw can be evenly applied.

[0015] Preferably, a lubrication mechanism is installed at the bottom of the housing, the lubrication mechanism is installed at the position of the lead screw, the lubrication mechanism includes an oil tank and a connecting sliding member, the oil tank is fixedly installed inside the housing and near the bottom, the connecting sliding member is slidably installed in the middle of the bottom of the housing and is installed directly below the lead screw, an oil inlet check valve is installed on the side of the top of the oil tank, the top of the oil inlet check valve is connected to a right angle pipe, an oil outlet check valve is installed on the surface of the oil inlet check valve and near the bottom, a hose is connected between the oil outlet check valve and the oil hole, and an oil pressure assembly is installed on the surface of the oil tank and near the top.

[0016] Preferably, the connecting sliding member is evenly installed in the middle of the bottom of the housing, the hose passes around the middle of the connecting sliding member, and the top of the right-angle tube penetrates the inner wall of the housing and extends to its outside.

[0017] Preferably, the oil pressing assembly includes a square pushing block and an elastic diaphragm. The square pushing block is slidably mounted on the surface of the oil tank near the top, and is sealed to the oil tank. The elastic diaphragm is fixedly connected to the inner wall of the oil tank, and its position corresponds to that of the square pushing block. A support member is fixedly mounted on the top of the square pushing block, away from the elastic diaphragm. The lead screw passes through a through hole in the center of the support member. A force-bearing rod is fixedly connected to the side of the top of the support member. As the sliding sleeve moves linearly driven by the lead screw, when the sliding sleeve and the T-shaped platform move the clamping mechanism to the end of the outer shell, the force-bearing rod is subjected to an outward pushing force, and the square pushing block... With the sliding connection of the moving block, the end of the square pushing block away from the support extends into the oil tank, causing the elastic membrane to expand under the pushing force. This squeezes the lubricating oil in the oil tank. Through the one-way control of the oil circuit by the inlet and outlet check valves, the lubricating oil in the oil tank enters the hose from the outlet check valve. Under the delivery of the hose, the lubricating oil enters the oil hole, and the balls come into contact with the lubricating oil. As the balls roll, they coat the spiral grooves on the surface of the lead screw with lubricating oil, thus lubricating the lead screw and balls as a whole. This reduces wear during linear transmission, extends the service life of the equipment, and connects the structures together through the interaction between them.

[0018] Preferably, the square push block is installed horizontally, and there are two force-bearing rods, which are installed symmetrically along the support member.

[0019] Preferably, a clamping mechanism is installed on the top of the T-shaped platform. The clamping mechanism includes a bearing plate, which is fixedly installed on the top of the T-shaped platform by screws and is located directly above the T-shaped platform. A clamping plate is rotatably installed on the side of the top of the bearing plate. A swing rod is fixedly connected to the bottom of the clamping plate. The bottom end of the swing rod passes through the center of the slotted hole. A reset spring is fixedly connected between the outer circular surface of the swing rod and the side of the surface of the T-shaped platform. When the clamping mechanism is moved to both ends by the T-shaped platform, the swing rod contacts the force rod, which causes the swing rod to be pressed inward. The reset spring is compressed, and the swing rod causes the clamping plate to unfold outward, facilitating the feeding and unloading of material on the top of the bearing plate.

[0020] Preferably, there are two clamping plates, which are symmetrically installed along the bearing plate. The swing rod is installed vertically, and the reset spring is arc-shaped. When the T-shaped platform moves to the other end, the swing rod disengages from the force rod, and under the elastic force of the reset spring, the swing rod is pushed outward. The swing rod can then drive the clamping plate to rotate in the opposite direction to reset, thus clamping and fixing the material on the top of the bearing plate, making it less likely for the material to shift or fall.

[0021] This invention provides a transmitter with a linear transmission device. It has the following advantages:

[0022] 1. The transmission device with linear transmission mechanism utilizes the rotation of the output end of the servo motor to drive the lead screw to rotate. The ball bearings are installed in the spiral groove on the surface of the lead screw. The rotation of the lead screw can apply a pushing force to the ball bearings, and the rolling of the ball bearings can transmit the pushing force to the sliding sleeve. Combined with the interaction between the guide hole and the T-shaped platform, the sliding sleeve and the T-shaped platform can be guided, thus enabling linear transmission between them.

[0023] Second, the transmission device with linear transmission mechanism moves linearly together with the sliding sleeve and the T-shaped platform. By using the I-shaped roller installed at the guide hole, the I-shaped roller can roll to support the sliding sleeve, thereby making the sliding sleeve move more smoothly and less prone to shaking.

[0024] Third, this transmission device with a linear drive mechanism utilizes the expansion of an elastic diaphragm under a driving force to compress the lubricating oil in the oil tank. Through one-way control of the oil circuit via inlet and outlet check valves, the lubricating oil in the oil tank enters the hose from the outlet check valve. Under the flow of the hose, the lubricating oil enters the oil hole, bringing the balls into contact with the lubricating oil. As the balls roll, they coat the spiral grooves on the screw surface with lubricating oil, thus lubricating the screw and balls as a whole. This reduces wear during linear transmission and extends the service life of the equipment.

[0025] Fourth, the transmission device with linear transmission mechanism uses a lead screw to pass through the center of an annular ring, and the annular ring moves linearly together with the sliding sleeve. The annular ring can cover the gap between the center hole of the sliding sleeve and the surface of the lead screw, reducing the entry of dust and impurities into the interior of the sliding sleeve, thus achieving a protective effect.

[0026] 5. The transmission device with linear transmission mechanism, as lubricating oil is applied to the spiral groove on the surface of the lead screw, and the ring is made of rubber material, the ring itself is flexible, and the ring makes flexible contact with the surface of the lead screw, which will not cause scratches to the surface of the lead screw. Furthermore, by using the sliding sleeve to drive the ring to move linearly, the lubricating oil adhering to the surface of the lead screw can be evenly applied.

[0027] VI. The transmission device with linear transmission device, when the entire clamping mechanism is driven to move to both ends by the T-shaped table, the swing rod contacts the force rod, so that the swing rod is subjected to inward pressing pressure, the reset spring is compressed, and the swing rod drives the clamping plate to unfold outward, which facilitates the feeding and unloading of materials on the top of the bearing plate.

[0028] 7. The transmission device with linear transmission mechanism disengages the swing rod from the force rod, and under the elastic force of the reset spring, the swing rod is pushed outward. The swing rod can drive the clamping plate to rotate in the opposite direction to reset, thus clamping and fixing the material on the top of the bearing plate, making it less likely for the material to shift or fall.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution:

[0041] A transmission device with a linear transmission mechanism includes:

[0042] The outer casing 1, and the guide holes 2 opened at the middle of the top and the middle of the bottom of the outer casing 1; the strip-shaped hole 3 is opened on the side of the top of the outer casing 1.

[0043] Drive mechanism 4, which is used for linear transmission, is installed in the middle of the inside of housing 1.

[0044] The drive mechanism 4 includes a servo motor 41 and a lead screw 42. The servo motor 41 is fixedly mounted on the side of the surface of the housing 1. The two ends of the lead screw 42 are rotatably mounted between the inner walls of the housing 1. The output end of the servo motor 41 is fixedly mounted to the lead screw 42 via a coupling. A sliding sleeve 43 is mounted on the surface of the lead screw 42, and the lead screw 42 passes through the center of the sliding sleeve 43. I-shaped rollers 44 are rotatably mounted on the top and bottom of the outer surface of the sliding sleeve 43, and the I-shaped rollers 44 are rolled between the guide holes 2. An annular ring 45 is fixedly mounted on the end face of the surface of the sliding sleeve 43. Ball bearings 46 are rolled between the spherical surfaces of the ball bearings 46 and the helical grooves on the surface of the lead screw 42. A T-shaped platform 47 is fixedly installed on the top of the outer circular surface of 43. An oil hole 48 is opened at the bottom of the annular ring 45. The oil hole 48 is located directly below the ball bearing 46. The lead screw 42 is rotated and installed in the middle of the inner shell 1. When the operator starts the servo motor 41, the rotation of the output end of the servo motor 41 can drive the lead screw 42 to rotate. The ball bearing 46 is rolled in the spiral groove on the surface of the lead screw 42. The rotation of the lead screw 42 can apply a pushing force to the ball bearing 46. The rolling of the ball bearing 46 transmits the pushing force to the sliding sleeve 43. Combined with the interaction between the guide hole 2 and the T-shaped platform 47, the sliding sleeve 43 and the T-shaped platform 47 can perform linear transmission.

[0045] The lead screw 42 is installed horizontally, and the servo motor 41 is installed at the same height as the lead screw 42. There are four I-shaped rollers 44, and the positions of the four I-shaped rollers 44 correspond to the positions of the guide holes 2. The sliding sleeve 43 and the T-shaped platform 47 move linearly together. By using the I-shaped rollers 44 installed at the positions of the guide holes 2, the I-shaped rollers 44 can roll and support the sliding sleeve 43, thereby making the movement of the sliding sleeve 43 more stable and less prone to shaking.

[0046] The lead screw 42 passes through the center of the ring 45, which is made of rubber. There are two rings 45, and the two rings 45 are symmetrically installed along the sliding sleeve 43.

[0047] By using the lead screw 42 to pass through the center of the annular ring 45, and the annular ring 45 moving linearly together with the sliding sleeve 43, the gap between the center hole of the sliding sleeve 43 and the surface of the lead screw 42 can be covered by the annular ring 45, reducing the entry of dust and impurities into the interior of the sliding sleeve 43, thus achieving a protective effect.

[0048] The balls 46 are evenly installed on the inner wall of the sleeve 43, and the spherical surface of the balls 46 fits into the spiral groove on the surface of the lead screw 42.

[0049] As the lubricating oil is applied to the spiral grooves on the surface of the lead screw 42, and the annular ring 45 is made of rubber, the annular ring 45 is flexible and makes flexible contact with the surface of the lead screw 42, which will not cause scratches to the surface of the lead screw 42. Furthermore, by using the sliding sleeve 43 to drive the annular ring 45 to move linearly, the lubricating oil adhering to the surface of the lead screw 42 can be evenly applied.

[0050] The second embodiment, based on the first embodiment, see Figures 1 to 8 As shown:

[0051] A lubrication mechanism 5 is installed at the bottom of the outer casing 1. The lubrication mechanism 5 is installed at the position of the lead screw 42. The lubrication mechanism 5 includes an oil tank 51 and a connecting sliding member 52. The oil tank 51 is fixedly installed inside the outer casing 1 and near the bottom. The connecting sliding member 52 is slidably installed at the middle of the bottom of the outer casing 1 and is installed directly below the lead screw 42. An oil inlet check valve 53 is installed on the side of the top of the oil tank 51. A right-angle pipe 54 is connected to the top of the oil inlet check valve 53. An oil outlet check valve 55 is installed on the surface of the oil inlet check valve 53 and near the bottom. A hose 56 is connected between the oil outlet check valve 55 and the oil hole 48. An oil pressure assembly 57 is installed on the surface of the oil tank 51 and near the top. The connecting sliding member 52 is slidably installed with the bottom of the outer casing 1, which facilitates the support of the hose 56 and helps the hose 56 to extend and retract, so that the structure will not get stuck.

[0052] The connecting sliding member 52 is evenly installed in the middle of the bottom of the housing 1, the hose 56 passes around the middle of the connecting sliding member 52, and the top of the right angle tube 54 penetrates the inner wall of the housing 1 and extends to its outside.

[0053] The hydraulic assembly 57 includes a square pusher block 571 and an elastic diaphragm 572. The square pusher block 571 is slidably mounted on the surface of the oil tank 51 near the top, and is sealed to the oil tank 51. The elastic diaphragm 572 is fixedly connected to the inner wall of the oil tank 51, and the position of the elastic diaphragm 572 corresponds to the position of the square pusher block 571. A support member 573 is fixedly mounted on the top of the square pusher block 571 away from the elastic diaphragm 572. A lead screw 42 passes through the through hole in the center of the support member 573. A force-bearing rod 574 is fixedly connected to the side of the top of the support member 573. As the sliding sleeve 43 is driven by the lead screw 42 to move linearly, when the sliding sleeve 43 and the T-shaped platform 47 drive the clamping mechanism 6 to move to the end of the outer casing 1, it causes... The force-bearing rod 574 is pushed outward, and under the sliding connection of the square push block 571, the end of the square push block 571 away from the support member 573 extends into the oil tank 51, causing the elastic membrane 572 to expand under the pushing force, which can squeeze the lubricating oil in the oil tank 51. Through the one-way control of the oil circuit by the oil inlet check valve 53 and the oil outlet check valve 55, the lubricating oil in the oil tank 51 can enter the interior of the hose 56 from the oil outlet check valve 55. Under the delivery of the hose 56, the lubricating oil enters the oil hole 48, and the ball 46 comes into contact with the lubricating oil. As the ball 46 rolls, it can apply lubricating oil to the spiral groove on the surface of the lead screw 42, thereby lubricating the lead screw 42 and the ball 46 as a whole.

[0054] The square push block 571 is installed horizontally, and there are two force-bearing rods 574, which are installed symmetrically along the support member 573.

[0055] The third embodiment, based on the first and second embodiments, see Figures 1 to 9 As shown:

[0056] A clamping mechanism 6 is installed on the top of the T-shaped platform 47. The clamping mechanism 6 includes a support plate 61, which is fixedly installed on the top of the T-shaped platform 47 by screws and is directly above the T-shaped platform 47. A clamping plate 62 is rotatably installed on the side of the top of the support plate 61. A swing rod 63 is fixedly connected to the bottom of the clamping plate 62. The bottom end of the swing rod 63 passes through the center of the strip hole 3. A reset spring 64 is fixedly connected between the outer circular surface of the swing rod 63 and the side of the surface of the T-shaped platform 47. When the clamping mechanism 6 is moved to both ends by the T-shaped platform 47, the swing rod 63 contacts the force rod 574, so that the swing rod 63 is subjected to inward pressing pressure, the reset spring 64 is compressed, and the swing rod 63 drives the clamping plate 62 to unfold outward, which facilitates the feeding and unloading of materials on the top of the support plate 61.

[0057] There are two clamping plates 62, which are symmetrically installed along the bearing plate 61. The swing rod 63 is installed vertically, and the reset spring 64 is arc-shaped. When the T-shaped platform 47 moves to the other end, the swing rod 63 disengages from the force rod 574. Under the elastic force of the reset spring 64, the swing rod 63 is pushed outward, which can drive the clamping plate 62 to rotate in the opposite direction to reset, thus clamping and fixing the material on the top of the bearing plate 61.

[0058] In use, the lead screw 42 is first rotated and installed in the middle of the housing 1. The operator starts the servo motor 41. The rotation of the output end of the servo motor 41 drives the lead screw 42 to rotate. The ball bearings 46 are rolled in the spiral groove on the surface of the lead screw 42. The rotation of the lead screw 42 can apply a pushing force to the ball bearings 46. The rolling of the ball bearings 46 transmits the pushing force to the sliding sleeve 43. Combined with the interaction between the guide hole 2 and the T-shaped platform 47, the sliding sleeve 43 and the T-shaped platform 47 can be guided, so that the sliding sleeve 43 and the T-shaped platform 47 can perform linear transmission. The rotation of the lead screw 42 drives the sliding sleeve 43 and the T-shaped platform 47 to move closer to the servo motor 41. The clamping mechanism 6 moves together with the T-shaped platform 47 to the side closer to the servo motor 41.

[0059] Furthermore, by using the contact between the swing rod 63 and the force rod 574, the swing rod 63 can be subjected to an inward pressing force, the reset spring 64 is compressed, and the swing rod 63 drives the clamping plate 62 to unfold outward, making it easier to place materials on the top of the bearing plate 61.

[0060] Simultaneously, when the sliding sleeve 43 and the T-shaped platform 47 drive the clamping mechanism 6 to move to the end of the outer shell 1, the force rod 574 is pushed outward, and under the sliding connection of the square push block 571, the end of the square push block 571 away from the support 573 extends into the oil tank 51, and the elastic membrane 572 is pushed and expanded, which can squeeze the lubricating oil in the oil tank 51. Through the one-way control of the oil circuit by the oil inlet check valve 53 and the oil outlet check valve 55, the lubricating oil in the oil tank 51 can enter the interior of the hose 56 from the oil outlet check valve 55. Under the delivery of the hose 56, the lubricating oil enters the oil hole 48, and the ball 46 comes into contact with the lubricating oil. As the ball 46 rolls, the lubricating oil can be applied to the spiral groove on the surface of the lead screw 42, thereby lubricating the lead screw 42 and the ball 46 as a whole.

[0061] Once the material is placed on top of the support plate 61, it can be powered again by the servo motor 41. By reversing the output of the servo motor 41, the lead screw 42 can be driven to rotate in the opposite direction, thereby driving the entire assembly to move away from the servo motor 41 through the sliding sleeve 43 and the T-shaped platform 47.

[0062] Furthermore, by disengaging the swing rod 63 from the force rod 574, and under the elastic force of the reset spring 64, the swing rod 63 is pushed outward, which can drive the clamping plate 62 to rotate in the opposite direction to reset, thereby clamping and fixing the material on the top of the bearing plate 61, and thus conveying the material.

[0063] Furthermore, by moving linearly together with the sliding sleeve 43 and the T-shaped platform 47, and by using the I-shaped roller 44 installed at the position of the guide hole 2, the I-shaped roller 44 can roll to support the sliding sleeve 43, thereby making the sliding sleeve 43 move more smoothly.

[0064] The lead screw 42 passes through the center of the annular ring 45, and the annular ring 45 moves linearly together with the sliding sleeve 43. The gap between the center hole of the sliding sleeve 43 and the surface of the lead screw 42 can be covered by the annular ring 45, reducing the entry of dust and impurities into the interior of the sliding sleeve 43.

[0065] As the lubricating oil is applied to the spiral groove on the surface of the lead screw 42, and the annular ring 45 is made of rubber, the annular ring 45 itself is flexible and makes flexible contact with the surface of the lead screw 42, so as not to scratch the surface of the lead screw 42. Furthermore, by using the sliding sleeve 43 to drive the annular ring 45 to move linearly, the lubricating oil adhering to the surface of the lead screw 42 can be evenly applied.

[0066] Furthermore, when the material is transported to the end away from the servo motor 41, the swing arm 63 can be pressed again by the force rod 574 installed at the other end, causing the swing arm 63 to drive the clamping plate 62 to rotate in the opposite direction, which can release the material on the top of the bearing plate 61, helping the external equipment robot to grab the material on the top of the bearing plate 61 for unloading.

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 a process, method, article, or apparatus.
