Description

Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, specifically a high-temperature resistant rubber sealing ring processing and grinding equipment. Background Technology

[0002] High-temperature resistant rubber is commonly used in high-temperature environments, such as seals in automotive engines, aerospace, or industrial equipment. These seals require precise grinding after processing to ensure sealing performance and service life; therefore, grinding equipment is needed for further processing of the high-temperature resistant rubber seals.

[0003] Existing grinding equipment for rubber seals cannot achieve batch processing of seal workpieces, and the installation of workpieces is often inconvenient, resulting in low production efficiency. Furthermore, when the grinding wheel contacts the seal workpiece, the degree of contact cannot be accurately and effectively controlled. Low contact degree leads to poor grinding effect, while excessive grinding wheel pressure will damage the workpiece. Therefore, we propose a high-temperature resistant rubber seal processing and grinding equipment. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome the existing defects and provide a high-temperature resistant rubber sealing ring processing and grinding equipment. Through an array of motors and grinding wheels, it can perform batch grinding of rubber rings, improving processing efficiency. It also facilitates the installation of workpieces on the upper side of the pull-out plate, and with the help of an automatically tensioning elastic sheet, it can further improve the processing efficiency of the equipment. It also features a reliable grinding wheel lowering unit, which, through the elastic action of a spring, ensures full contact between the grinding wheel and the rubber ring, thereby improving the thoroughness and flatness of the grinding. Furthermore, during continuous pressing, a pressure sensor can detect the instant of contact between the protrusion and the insertion rod, thereby timely controlling the hydraulic cylinder to stop working and preventing excessive pressing of the grinding wheel from damaging the workpiece. A chip extraction machine is also included to remove grinding debris. It also accelerates the airflow inside the mounting box, allowing the rubber sealing rings to effectively dissipate heat during the grinding process, thus enabling the sealing ring workpiece to effectively cope with the high temperatures generated during grinding. This effectively solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant rubber sealing ring processing and grinding equipment, comprising an installation box, a workpiece loading unit, and a grinding wheel lowering unit;

[0006] Installation box: It is a hollow cuboid structure;

[0007] Workpiece loading unit: includes a pull-out plate, motor, support block, insert rod, elastic sheet and control machine. The mounting box has sliding grooves on both sides at the lower position. The pull-out plate is slidably connected to the bottom side of the mounting box. The upper end of the pull-out plate is embedded with 20 motors in 4 rows and 5 columns. The output shaft of the motor faces upward and is fixedly connected to the lower center of the circular support block. The upper center of the support block is fixedly connected with a vertical insert rod. The upper end of the insert rod is chamfered, and four elastic sheets are fixedly connected in a circumferential array on the outer side of the insert rod. The lower ends of the four elastic sheets are all extended outward. The front end of the pull-out plate has a double-layer stepped structure, and the control machine is embedded in the lower front end of the plate.

[0008] Mold lowering unit: Installed on the top inside the mounting box.

[0009] The pull-out plate can be extended outwards to facilitate the installation of the rubber sealing ring. The sealing ring to be processed passes through the insert rod from the top and is placed on the upper side of the support block. When the elastic sheet is compressed, it will press against the inner side of the rubber ring, thereby securing the rubber ring. The motor is used to drive the support block and the rubber ring to rotate, and works with the grinding wheel on the upper side to polish the sealing ring. Through the array of motors and grinding wheels, the rubber rings can be polished in batches, improving processing efficiency. The control machine is used to control the synchronous start and stop of each motor.

[0010] Furthermore, the grinding wheel lowering unit includes hydraulic cylinders, mounting blocks, telescopic rods, springs, and grinding wheels. Four rows of five hydraulic cylinders are embedded in the top inner side of the mounting box. Each hydraulic cylinder corresponds vertically to a motor. The telescopic end of the hydraulic cylinder extends downwards and is fixedly connected to a circular mounting block at its end. Four telescopic rods are fixedly connected in a circular array at the lower end of the mounting block. The telescopic rods are vertically positioned, and an annular grinding wheel is fixedly mounted at their lower ends. Springs are fitted around the outer sides of the telescopic rods. The hydraulic cylinders drive the mounting blocks and grinding wheels downwards. When the grinding wheel contacts the sealing ring, the telescopic rods and springs act as a buffer, and the springs push the grinding wheel against the upper side of the sealing ring, ensuring full contact between the grinding wheel and the rubber ring, thereby improving the thoroughness and flatness of the grinding.

[0011] Furthermore, the grinding wheel lowering unit also includes a protrusion, a pressure sensor, and a PLC controller. A protrusion is fixedly connected to the center of the lower side of the mounting block, and a pressure sensor is embedded in the lower end of the protrusion. A PLC controller is embedded in the top front of the mounting box, and a manual control board is located to the right of the PLC controller. The hydraulic cylinder and the pressure sensor are both bidirectionally electrically connected to the PLC controller. During continuous pressing, when the lower end of the protrusion contacts the upper end of the insertion rod, the pressure sensor detects the contact and sends a signal to the PLC controller, thereby promptly stopping the hydraulic cylinder and preventing excessive pressing of the grinding wheel.

[0012] Furthermore, the workpiece loading unit also includes a snap-fit ​​sliding rod, an iron block, and an electromagnetic lock switch. A snap-fit ​​sliding rod is fixedly connected to both the left and right sides of the pull-out plate. The snap-fit ​​sliding rod is inserted into and slidably connected in a groove opened inside the mounting box. An iron block is installed on the rear side of the groove. An electromagnetic adsorption lock is embedded in the rear end of the snap-fit ​​sliding rod. An electromagnetic lock switch is installed at the front right position of the pull-out plate. The snap-fit ​​sliding rod is used for the sliding connection between the pull-out plate and the mounting box. By installing the iron block and the electromagnetic adsorption lock, the pull-out plate can be locked after it is installed in place. The electromagnetic lock switch is used to control the activation and deactivation of the electromagnetic adsorption lock.

[0013] Furthermore, it also includes a lock adjustment wheel and a movable baffle. A transverse connecting shaft is fixedly connected to the middle position of the stepped structure at the front end of the pull-out plate, and a movable baffle is rotatably connected to it via the connecting shaft. Lock tongues and lock adjustment wheels are embedded in the left and right corners of the upper side of the movable baffle. The inner shaft of the lock adjustment wheel engages with the lock tongue. A lock hole is provided at the upper part of the front end of the mounting box. By rotating the lock adjustment wheel, the lock tongue inside the movable baffle can be controlled to extend or retract, thereby realizing the locking and unlocking process. When the movable baffle is raised, it can close the front end of the mounting box to prevent grinding debris from flying out. When the movable baffle is laid flat outwards, it facilitates loading materials onto the pull-out plate.

[0014] Furthermore, the system also includes a debris extraction machine. The debris extraction machine is embedded in the rear side of the mounting box, with its suction port facing inwards and its discharge port facing outwards. The debris extraction machine is used to absorb debris generated during the grinding process and discharge it outwards. Furthermore, the extraction action of the debris extraction machine accelerates the airflow inside the mounting box, effectively dissipating heat from the rubber sealing ring during the grinding process, thus enabling the sealing ring workpiece to effectively cope with the high temperatures generated during grinding.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-temperature resistant rubber sealing ring processing and grinding equipment has the following advantages:

[0016] 1. The array of motors and grinding wheels enables batch grinding of rubber rings, improving processing efficiency; it also facilitates the installation of workpieces onto the upper side of the pull plate, and the automatic tensioning elastic sheet increases the speed of workpiece installation, further improving the processing efficiency of the equipment.

[0017] 2. It has a reliable grinding wheel lowering unit. Through the elastic action of the spring, it can ensure full contact between the grinding wheel and the rubber ring, thereby improving the fullness and flatness of grinding. In addition, during the continuous pressing process, the pressure sensor can detect the moment of contact between the protrusion and the insertion rod, thereby controlling the hydraulic cylinder to stop working in time to prevent the grinding wheel from being pressed down too much.

[0018] 3. This utility model, through the array of motors and grinding wheels, enables batch grinding of rubber rings, improving processing efficiency. It also facilitates the installation of workpieces onto the upper side of the pull-out plate, and the automatic tensioning elastic sheet further enhances the equipment's processing efficiency.

The sealing ring to be processed passes through the insertion rod 24 from the top and is placed on the upper side of the support block 23. The elastic sheet 25 is squeezed and presses against the inner side of the rubber ring, thereby securing the rubber ring. The motor 22 is used to drive the support block 23 and the rubber ring to rotate, and works with the grinding wheel 35 on the upper side to grind the sealing ring.

By installing the iron block 27 and the electromagnetic adsorption lock, the pull-out plate 21 can be locked after it is inserted into place. The electromagnetic lock switch 28 is used to control the activation and deactivation of the electromagnetic adsorption lock.

[0035] It also includes a lock adjustment wheel 5 and a movable baffle 6. A horizontal connecting shaft is fixedly connected to the middle position of the stepped structure at the front end of the pull-out plate 21, and the movable baffle 6 is rotatably connected to it through the connecting shaft. Lock tongues and lock adjustment wheels 5 are embedded in the left and right corners on the upper side of the movable baffle 6.

Through the extraction action of the chip extractor 4, the airflow inside the mounting box 1 can be accelerated, so that the rubber sealing ring can be effectively cooled during the grinding process, thereby enabling the sealing ring workpiece to effectively cope with the high temperature generated during grinding.

[0037] The working principle of the high-temperature resistant rubber sealing ring processing and grinding equipment provided by this utility model is as follows: This equipment, through the array of motors 22 and grinding wheels 35, can perform batch grinding of rubber rings, improving processing efficiency; it also facilitates the installation of workpieces on the upper side of the pull-out plate 21, and with the automatic tensioning elastic sheet 25, the processing efficiency of the equipment can be further improved: Twenty motors 22 in four rows and five columns are embedded in the upper end of the pull-out plate 21, and hydraulic cylinders 31 in four rows and five columns are embedded in the top inner side of the mounting box 1. The pull-out plate 21 can be pulled outwards to facilitate the grinding of rubber rings. The rubber sealing ring is installed by passing the insert rod 24 through the top and placing it on the upper side of the support block 23. The elastic sheet 25 is squeezed and presses against the inner side of the rubber ring, thus securing the rubber ring.

The hydraulic cylinder 31 controls the grinding wheel 35 to contact the workpiece. Through the array of motors 22 and grinding wheels 35, the rubber rings can be batch-ground, improving processing efficiency.

Through the elastic action of the spring 34, it ensures that the grinding wheel 35 makes full contact with the rubber ring, thereby improving the thoroughness and flatness of the grinding. The hydraulic cylinder 31 is used to drive the mounting block 32 and the grinding wheel 35 to move downward. After the grinding wheel 35 touches the sealing ring, the telescopic rod 33 and the spring 34 will have a buffering effect, and the spring 34 can push the grinding wheel 35 against the upper side of the sealing ring, ensuring that the grinding wheel 35 makes full contact with the rubber ring, thereby improving the thoroughness and flatness of the grinding. During the continuous pressing process, the pressure sensor 37 can detect the moment of contact between the protrusion 36 and the insertion rod 24, thereby timely controlling the hydraulic cylinder 31 to stop working and preventing the grinding wheel 35 from being pressed down excessively. In addition, the chip extractor 4 is used to absorb the chips generated during the grinding process and discharge them outwards. The extraction action of the chip extractor 4 can accelerate the airflow inside the mounting box 1, so that the rubber sealing ring can be effectively cooled during the grinding process, thus enabling the sealing ring workpiece to effectively cope with the high temperature generated during grinding. The snap-fit ​​slide rod 26 is used for the sliding connection between the pull plate 21 and the mounting box 1. With the installation iron block 27 and the electromagnetic adsorption lock, the pull plate 21 can be locked after it is installed in place. The electromagnetic lock switch 28 is used to control the start and stop of the electromagnetic adsorption lock. By rotating the lock adjustment wheel 5, the locking tongue inside the movable baffle 6 can be controlled to extend or retract, thereby realizing the locking and unlocking process. When the movable baffle 6 is raised, it can close the front end of the mounting box 1 to prevent grinding chips from flying out. When the movable baffle 6 is laid flat outwards, it is convenient to load materials onto the pull plate 21.

[0038] It is worth noting that the control machine 29 controlling the motor 22, the PLC controller 38 controlling the hydraulic cylinder 31, and the electromagnetic lock switch 28 controlling the electromagnetic adsorption lock all use methods commonly used in the prior art in the above embodiments.
