Description

Technical Field

[0001] The utility model relates to the technical field of push cylinder equipment, in particular to a high-torque push cylinder. Background Art

[0002] In order to facilitate the control of the equipment to perform linear reciprocating movement, it is often necessary to use a push cylinder device to convert the rotation of the motor into linear reciprocating movement. The utility model patent with patent application number CN202323369807.6 discloses a new push cylinder, in which the output end of the driving mechanism is connected to the input end of the reversing mechanism; the output end of the reversing mechanism is connected to the input end of the ball screw mechanism, which can drive the ball screw mechanism to move; the output end of the ball screw mechanism is connected to the push plate; by setting the reversing mechanism, the size of the linear transmission is reduced, making the mechanism more compact; by setting a pair of position sensors, the push rod stroke can be controlled. According to the technical solution disclosed by it, when the existing push cylinder device is in use, on the one hand, when the device movement is subject to large resistance during operation, it is easy to cause the transmission mechanism or the motor to be damaged due to excessive resistance, which is not conducive to ensuring the safety of the push cylinder device. On the other hand, when the push cylinder device is disengaged due to excessive resistance, personnel are often required to reconnect the disengaging mechanism, increasing manpower consumption.

[0003] Therefore, how to design a high-torque push cylinder has become our current problem to be solved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-torque push cylinder to solve the problems raised in the above background technology. The utility model has a reasonable design and is relatively convenient to use. It is suitable for pushing equipment to perform reciprocating movements.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-torque push cylinder, including a support plate and a sliding rod, a pushing assembly is installed on the sliding rod, the pushing assembly includes a push cylinder and a screw, a driving assembly is installed on the top of the push cylinder, the driving assembly includes a motor and a reducer, a protective assembly is installed on one side of the support plate, the protective assembly includes a support box and a rotating plate, a transmission assembly is installed on the inner side of the support box, the transmission assembly includes gear 1 and gear 2, a limiting assembly is arranged on the gear 2 and the rotating plate, the limiting assembly includes a card slot and a bayonet, a locking assembly is installed on the inner side of the card slot, and the locking assembly includes a pin and a spring.

[0006] Furthermore, both ends of the sliding rod are welded to the support plate, the sliding rods are evenly distributed at the four corners of the support plate, and the push cylinder sleeve is arranged on the outer side of the sliding rod.

[0007] Furthermore, one side of the reducer is mounted on the support plate by bolts, the motor is mounted on the other side of the reducer by bolts, and the support box is mounted on one side of the support plate by bolts.

[0008] Furthermore, one side of the gear 1 passes through the support box and the support plate through a bearing and is key-connected to the output shaft of the reducer, and the transmission shaft of the reducer is key-connected to the output shaft of the motor.

[0009] Furthermore, both ends of the screw are mounted on the inner side of the support plate through bearings, the screw is mounted on the inner side of the push cylinder through threads, the rotating plate is mounted on the inner side of the support box, and one end of the screw passes through the support plate and the support box and is keyed to the center of the rotating plate.

[0010] Furthermore, the gear 2 is sleeved on the outer side of the rotating plate, the outer sides of the gear 1 and the gear 2 are sleeved with a steel belt, the inner wall of the steel belt is provided with teeth, and the gear 1 and the gear 2 are both engaged with the teeth.

[0011] Furthermore, the slot is provided on the inner side of the gear 2, the bayonet is provided on the outer side of the rotating plate, and one end of the bayonet pin is connected to the inner wall of the slot via a spring.

[0012] Furthermore, the other end of the bayonet passes through the slot and extends to the inner side of the bayonet. A fine hole is provided on the inner side of the gear 2, and the slot is connected to the outer side of the gear 2 through the fine hole.

[0013] Beneficial effects: 1. When the high-torque push cylinder is in use, the motor drives the reducer to rotate, and after being decelerated by the reducer, the steel belt is driven to rotate through gear 1. The steel belt drives gear 2 to further decelerate and then drives the turn plate to rotate through the pin, thereby driving the screw rod to rotate on the inside of the push cylinder. The push of the screw rod makes the push cylinder and the support plate move relative to each other, thereby realizing the linear reciprocating movement of the equipment. When the equipment is subject to greater resistance, the screw rod blocks the rotation of the turn plate. After the resistance of the bayonet is greater than the elastic force of the spring, the pin in the bayonet compresses the spring and moves to the inside of the slot, thereby causing gear 2 to be disengaged from the turn plate, thereby avoiding damage to the steel belt or motor due to excessive resistance of the turn plate to the equipment, thereby ensuring the safe operation of the equipment.

[0014] 2. When the high-torque push cylinder is in use, when the bayonet is pushed to the inner side of the slot by the bayonet, the air in the slot is squeezed to the outside of gear two through the fine holes. When gear two moves the bayonet to the next bayonet driven by the steel belt, the spring pushes the bayonet to move into the bayonet, and the air in the slot is slowly sucked in through the fine holes, causing the bayonet to slowly move into the bayonet. If the resistance of the equipment still does not disappear at this time, the bayonet pin will still be pushed out by the bayonet. At the same time, the contact amount between the bayonet pin and the bayonet is small, reducing the wear of the bayonet and the bayonet pin. Until the resistance of the equipment is eliminated, the bayonet pin is pushed to the inner side of the bayonet by the spring, thereby realizing the automatic connection between the bayonet pin and the bayonet, saving manpower.

[0015] 3. The high torque push cylinder is reasonably designed and is more efficient and convenient to use. It is suitable for pushing equipment for reciprocating movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0022] See also Figures 1 to 4The present invention provides a technical solution: a high-torque push cylinder, including a support plate 1 and a slide rod 2, a pushing assembly is installed on the slide rod 2, the pushing assembly includes a push cylinder 3 and a screw 4, a driving assembly is installed on the top of the push cylinder 3, and the driving assembly includes a motor 6 and a reducer 7. A protective assembly is installed on one side of the support plate 1, and the protective assembly includes a support box 5 and a rotating plate 11. A transmission assembly is installed on the inner side of the support box 5, and the transmission assembly includes a gear 1 8 and a gear 2 9. A limit assembly is provided on the gear 2 9 and the rotating plate 11, and the limit assembly includes a slot 12 and a bayonet 13. A locking assembly is installed on the inner side of the slot 12, and the locking assembly includes a pin 14 and a spring 15. The slot 12 is opened on the inner side of the gear 2 9, and the bayonet 13 is opened on the outer side of the rotating plate 11. One end of the pin 14 is connected to the inner wall of the slot 12 by a spring 15, and the other end of the pin 14 passes through the slot 12 and The inner side of the gear 2 9 is provided with a small hole 16, and the slot 12 is connected to the outer side of the gear 2 9 through the small hole 16. When the bayonet 14 is pushed to the inner side of the slot 12 by the bayonet 13, the air in the slot 12 is squeezed to the outer side of the gear 2 9 through the small hole 16. When the gear 2 9 moves the bayonet 14 to the next bayonet 13 under the drive of the steel belt 10, the spring 15 pushes the bayonet 14 to move into the bayonet 15, and the air in the slot 12 is squeezed out through the small hole 16. Air is slowly inhaled through the pores 16, causing the bayonet 14 to slowly move into the bayonet 13. If the resistance of the device has not disappeared at this time, the bayonet 14 will still be pushed out by the bayonet 13. At the same time, the contact amount between the bayonet 14 and the bayonet 13 is small, reducing the wear of the bayonet 13 and the bayonet 14. Until the resistance of the device is eliminated, the bayonet 14 is pushed to the inner side of the bayonet 13 by the spring 15, thereby realizing the automatic connection between the bayonet 14 and the bayonet 13, saving manpower.

[0023] In this embodiment, both ends of the sliding rod 2 are welded to the support plate 1, and the sliding rod 2 is evenly distributed at the four corners of the support plate 1. The push cylinder 3 is sleeved on the outer side of the sliding rod 2, and one side of the reducer 7 is mounted on the support plate 1 by bolts, and the motor 6 is mounted on the other side of the reducer 7 by bolts, and the support box 5 is mounted on one side of the support plate 1 by bolts, and one side of the gear 1 8 passes through the support box 5 and the support plate 1 through a bearing and is keyed to the output shaft of the reducer 7, and the transmission shaft of the reducer 7 is keyed to the output shaft of the motor 6, and both ends of the screw rod 4 are mounted on the inner side of the support plate 1 through bearings, and the screw 4 is mounted on the inner side of the push cylinder 3 by a thread, and the rotating plate 11 is mounted on the inner side of the support box 5, one end of the screw 4 passes through the support plate 1 and the support box 5 and is keyed to the center of the rotating plate 11, and the gear 2 9 is sleeved on the outer side of the rotating plate 11, and the outer sides of the gear 1 8 and the gear 2 9 are sleeved with a steel belt 10 The gear 11 is then moved to the inside of the gear 12, and the gear 12 is then disengaged from the gear 11, thereby preventing the steel belt 10 or the motor 6 from being damaged due to excessive resistance of the equipment on the rotating plate 11, and thus ensuring the safety of the equipment.

[0024] The high-torque push cylinder provides electrical energy to all electrical equipment through an external power supply. When in use, the motor 6 drives the reducer 7 to rotate. After being decelerated by the reducer 7, the steel belt 10 is driven to rotate through the gear 1 8. The steel belt 10 drives the gear 2 9 to be further decelerated and then drives the rotating plate 11 to rotate through the bayonet 14, thereby driving the screw rod 4 to rotate on the inner side of the push cylinder 3. The push of the screw rod 4 makes the push cylinder 3 and the support plate 1 move relative to each other, thereby realizing the linear reciprocating movement of the equipment. When the equipment encounters a large resistance, the screw rod 4 blocks the rotation of the rotating plate 11. After the bayonet 13 in the bayonet 13 is subjected to a resistance greater than the elastic force of the spring 15, the bayonet 14 compresses the spring 15 and moves to the inside of the slot 12, thereby causing the gear 2 9 to be disengaged from the rotating plate 11, thereby avoiding the steel belt 10 or the electrical equipment from being damaged due to excessive resistance of the rotating plate 11 to the equipment. When the resistance of the equipment is eliminated, the bayonet 14 is pushed to the inner side of the bayonet 13 by the bayonet 13, and the air in the bayonet 12 is squeezed to the outer side of the gear 2 9 through the fine hole 16. When the gear 2 9 is driven by the steel belt 10 to transfer the bayonet 14 to the next bayonet 13, the spring 15 pushes the bayonet 14 to move into the bayonet 15, and the air in the bayonet 12 is slowly sucked in through the fine hole 16, thereby causing the bayonet 14 to slowly move into the bayonet 13.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
