Description

Technical Field

[0001] The utility model relates to the technical field of rubber diaphragm pressing, in particular to a quick pressing device with a protective function. Background Art

[0002] Rubber diaphragms are widely used in flow, pressure, differential and other valves, regulating valves, automatic mechanical followers, switches and counters. Rubber diaphragms have high wear resistance, excellent sealing performance, low cost and long service life, which are very important for mechanical equipment.

[0003] The rubber diaphragm lamination device is a key device for firmly bonding the rubber diaphragm to the metal plate or other substrates. At present, many lamination devices are not laminating smoothly, resulting in quality differences in the lamination process of the rubber diaphragm, which affects the performance and service life of the product after lamination. At the same time, the safety of the operator also needs to be guaranteed. Utility Model Content

[0004] The purpose of the utility model is to provide a quick pressing device with a protective function to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The pressing device is used to press the rubber diaphragm. The pressing device includes a frame, a workbench, a positioning device, a pressing mechanism, a protective device and a base. The frame and the base are fixedly connected, the frame and the pressing mechanism are fixedly connected, a number of workbenches are arranged circumferentially along the upper surface of the protective device, the workbench and the positioning device are fixedly connected, and the protective device and the base are fixedly connected.

[0007] The rubber diaphragm is placed on the workbench. A positioning device is set on the workbench to automatically position and detect the rubber diaphragm. The pressing mechanism is driven to rise and fall to press the rubber diaphragm. The pressing mechanism is fixed on the frame. The protective device rotates after the rubber diaphragm pressing process is completed, and the workbench is transferred to facilitate subsequent manual operation of the pressed rubber diaphragm to prevent workers from being injured when the pressing mechanism is raised and lowered. It plays a safety protection function, and the base fixes the protective device.

[0008] Furthermore, a placement groove is provided on the workbench, and the rubber diaphragm is placed in the placement groove. The rubber diaphragm is placed in the placement groove to perform a preliminary positioning on the rubber diaphragm.

[0009] Furthermore, the positioning device includes a light emitter and a photoresistor. Several light emitters and photoresistors are arranged on the workbench. Several light emitters are arranged along the tangent direction of the placement groove. Each light emitter and photoresistor constitutes a group of detection circuits. Light emitters and photoresistors in the same group are arranged facing each other.

[0010] When the pressing mechanism presses the rubber diaphragm, the position of the rubber diaphragm needs to be positioned to prevent position deviation from causing uneven force and affecting the flatness. The positioning device is used to position the rubber diaphragm placed on the workbench to ensure flatness. The characteristic that the resistance of the photoresistor decreases rapidly when exposed to light is utilized. When the light emitter emits a light beam to illuminate the photoresistor, the resistance decreases rapidly. Several light emitters on the workbench emit a light beam along the tangent direction of the mounting groove, and form a group of detection circuits with the photoresistors arranged opposite to each other. When the rubber diaphragm is placed in an offset position, there is an obstacle between the light emitter and the photoresistor, the photoresistor cannot receive the light source, and the resistance remains unchanged. The flatness of the rubber diaphragm pressing can be ensured by this positioning device.

[0011] Furthermore, the pressing mechanism includes a driving cylinder, a pressing block and a guide rail, the driving cylinder and the frame are fixedly connected, the driving cylinder and the pressing block are fixedly connected, the guide rail and the frame are fixedly connected, a guide groove is provided on the guide rail, and the pressing block and the guide rail are slidably connected.

[0012] The driving cylinder is fixed on the frame. The driving cylinder converts the pressure of compressed air into mechanical energy for reciprocating linear motion. The driving cylinder drives the pressing block to reciprocate to press the rubber diaphragm. The guide rail guides the pressing block to reciprocate in the vertical direction to ensure the correct running trajectory, improve the stability of the lifting and lowering during the pressing process, and achieve accurate pressing of the rubber diaphragm.

[0013] Furthermore, the driving cylinder includes a front end cover, a cylinder barrel, a piston, a sliding rod and a rear end cover. A sliding cavity is provided on the cylinder barrel. The piston and the sliding cavity of the cylinder barrel are slidingly connected. The piston and the sliding rod are fixedly connected. The front end cover and the cylinder barrel are fixedly connected. The rear end cover and the cylinder barrel are fixedly connected. The rear end cover and the frame are fixedly connected. The sliding rod and the pressing block are fixedly connected.

[0014] The driving cylinder is a device that drives the pressing mechanism to rise and fall. When compressed air enters the cylinder from one end, the air pressure will push the piston to move in the opposite direction, thereby driving the sliding rod to move in a straight line. When compressed air enters from the other end, the piston will move in the opposite direction to achieve reciprocating motion. The movement speed and force of the cylinder can be controlled by adjusting the intake pressure. A sliding chamber is provided in the cylinder barrel, and the piston can slide freely in the barrel. One side of the piston will receive the force of compressed air to push the piston to move along the cylinder barrel. The sliding rod extends out of the cylinder barrel. When the piston moves in the cylinder, the sliding rod will move in a straight line accordingly. The two end covers are used to close the cylinder barrel. The end covers are provided with air ports for connecting the air source. The driving cylinder is fixed to the frame through the rear end cover. The sliding rod is connected to the pressing block. The sliding rod drives the pressing block to rise and fall through reciprocating motion, and the pressing block presses the rubber diaphragm.

[0015] Furthermore, the protective device includes a steering wheel and a motor, a motor housing and a base are fixedly connected, a motor output end and a steering wheel are fixedly connected, and a steering wheel and a workbench are fixedly connected.

[0016] After the rubber diaphragm lamination process is completed, the motor drives the steering wheel to rotate, and the steering wheel drives the workbench to rotate. The laminated rubber diaphragm is transferred from under the lamination mechanism to a safe area, which is convenient for workers to operate and plays a role in safety protection. At the same time, it plays the role of automatic feeding, lamination and transfer.

[0017] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model utilizes the performance of photoresistors, emits a light beam along the tangent direction of the placement groove through a number of light emitters on the workbench, and forms a group of detection circuits with the photoresistors arranged opposite to each other, so as to position the rubber diaphragm and ensure the flatness of the pressing; utilizes a driving cylinder to drive the pressing block to perform reciprocating motion to press the rubber diaphragm, and the guide rail guides the pressing block to ensure the correct running trajectory, improves the stability of the lifting during the pressing process, and achieves accurate pressing of the rubber diaphragm; the steering wheel is driven by a motor to rotate, and the steering wheel drives the workbench to rotate, and the pressed rubber diaphragm is transferred from under the pressing mechanism to a safe area, which is convenient for workers to operate and plays a role in safety protection, while also playing the role of automatic feeding, pressing, and transfer.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides the following technical solutions:

[0028] like Figure 1 The pressing device is used to press the rubber diaphragm 1.

[0029] The rubber diaphragm 1 is placed on the workbench 3. A positioning device 4 is arranged on the workbench 3 to automatically position and detect the rubber diaphragm 1.

The base 7 fixes the protective device 6.

[0030] like Figure 2 A placement groove 31 is provided on the workbench 3, and the rubber diaphragm 1 is placed in the placement groove 31. The rubber diaphragm 1 is placed in the placement groove 31 to perform a preliminary positioning on the rubber diaphragm 1.

[0031] like Figure 2 The positioning device 4 includes a light emitter 41 and a photoresistor 42. A plurality of light emitters 41 and a plurality of photoresistors 42 are arranged on the workbench 3. The plurality of light emitters 41 are arranged along the tangent direction of the placement groove 31. Each light emitter 41 and photoresistor 42 constitutes a group of detection circuits. The light emitters 41 and photoresistors 42 in the same group are arranged facing each other.

[0032] When the pressing mechanism 5 presses the rubber diaphragm 1, the position of the rubber diaphragm 1 needs to be positioned to prevent position deviation from causing uneven force and affecting the flatness. The positioning device 4 is used to position the rubber diaphragm 1 placed on the workbench 3 to ensure flatness. The characteristic that the resistance of the photoresistor 42 decreases rapidly when exposed to light is utilized. When the light emitter 41 emits a light beam to illuminate the photoresistor 42, the resistance decreases rapidly. Several light emitters 41 on the workbench 3 emit a light beam along the tangent direction of the placement groove 31, and form a group of detection circuits with the photoresistors 42 arranged opposite to each other. When the placement position of the rubber diaphragm 1 is offset, there is an obstacle between the light emitter 41 and the photoresistor 42, the photoresistor 42 cannot receive the light source, and the resistance remains unchanged.
