New description: [New technical field] The present invention is a kind of cylinder device, especially a cylinder device that can generate fixed thrust or pressure and adjust the stroke coaxially. [Prior Art] It is quite common and inexpensive to use a pneumatic cylinder to push and apply a pressurizing device. However, if the pressurizing force is precisely controlled, "Pure ground pneumatic cylinders are difficult to achieve, the main reason. The piston in the pneumatic cylinder has a soft gasket in close contact with the gas for the sake of airtightness, so the piston is in the process of moving. The base is in motion and the inner wall of the cylinder is large and unpredictable. The frictional resistance knows that the theoretical thrust of the rolling cylinder will be reduced by 5% to 10%. The effect of the control is different depending on the pressure of the cylinder and the degree of slippage of the inner wall of the cylinder. . The difference between the four (4) cylinder thrusts can not be achieved. [New content] (4) Shi Shue The main purpose of this creation is to provide a kind of pressure or thrust that can produce solid strength. In order to achieve the above objectives, the set of thrust strokes of the creation includes a cylinder block, a piston step y, and a flat set Η Η Chushan stroke actuating device.

Position, when the workpiece is contacted, the gas & continues to retract the tension magazine' and the workpiece dusting force is set by the position of the cylinder stroke adjusting screw to set the spring compression amount to a constant pressure 'the bottom dead center lever has a slinging portion that limits the amount of machining that can be continued after the thrust seat reaches the working position, and the piston is oppositely directed from the second end of the cylinder toward the first end When moving, the piston rod pushes the retracting rod to multiply the thrusting spear to the initial position. Thereby, when the piston rod pushes the propulsion disc, the tension spring and the thrust seat will move synchronously and be pressed on the working head. After the work, the propulsion plate is continuously pushed by the piston rod, and after the cylinder stroke adjustment screw contacts the cylinder body, the tension spring is compressed to be converted into a fixed thrust, and the thrust seat can be connected to a working head, and the machining stroke of the working head is pushed. The position of the stop of the bottom dead center control lever is adjusted by the M315788 and the control is able to achieve the function of adjusting the fixed thrust and the maximum machining amount [in the embodiment]. The purpose of this creation is to achieve the above purpose and characteristics.

In this example, the cylinder 1 is further provided with a fixed seat 15'. 151, the lower dead "the control 柃 3 1 is correspondingly provided - can be screwed to the external threaded hole 1 0.001 outer thread segment 312, can be positioned relative to the cylinder i, while by the The upper end of the dead point control lever 31 is provided with a switch 313 for synchronizing the rotation of the bottom dead center control lever 31' to form a linear movement relative to the straight cubic upward thrust seat of the cylinder 1, and the rotary button 313 can be further The corresponding scale is marked to accurately align the position of the stop portion 3 ι of the bottom dead center control lever 31 and is fixed by the lock nut 16. Alternatively, the bottom end of the thrust seat 33 can be stepped into a working head 37. , 4 ji head 37 can be __ ultrasonic plastic joints, used to directly contact a workpiece after welding processing. Also 'side piston 22 When the ground is moved from the first end portion of the cylinder block 1 toward the second end portion 12, the piston rod 21 can be moved downward and the propulsion plate 32 abuts against the lower end of the piston rod 21, which can be a piston; 21 driving to press the tension spring 34 to move, thereby pushing the thrust seat: from an initial position to a working position, and vice versa, in the piston Μ opposite: from the second end 12 of the cylinder 1 to the first When the end n direction shifts: the piston rod 2 1 can apply t # Μ, Ω, J to push the retracting rod 35 to move the push base 33 to the initial position, in this case, the retreat The rod μ has a body 3 5 1 and a retracting plate 352 for contacting the upper end of the soil drier 21, wherein the body 351 is provided with a threaded section at one end, and the retracting plate 352 is The M315788 can be adapted to the initial position of the retracting plate 352 by the adjustable 盥" 54 screwed to the thread segment 353. Further, it is determined that the thrust seat 33, the other four plug rods 2 1 , and the retracting rods 35 are all formed by the middle retracting rod 35 covering the bottom dead center · the work μ straight cubic 6 μ process 31 and coaxial The piston rod 21 is also sheathed outside the retracting rod 35 and can also slide coaxially in the straight cube direction. The outer configuration 'starts, the piston rod 2" 隹 32, the tension spring 34 and the thrust seat 33 move downward, and when the working head 37 " head 37 is also synchronized 32 is pushed by the piston rod 21: | At this time, the thrust plate and the thrust seat 33 and the work force: the tension spring 34 ^ / and the master 37 pressure, the pressure is adjusted by the adjustment: the cylinder stroke adjustment screw 36 and the cylinder 1 The relative position is set to the compression process of the compression magazine 34 to generate a spring force and start machining, and the machining is performed until the sea thrust seat 33 touches the supporting portion 3 ι of the bottom dead center control lever 32, and then moves q downward. Therefore, the set maximum machining amount can be reached. Thus, the tension spring 34 will generate a constant (four) reduction amount f every time the servo stroke is obtained. According to Hooke's law, the compression amount of the tension spring 34 is proportional to the elastic force. As long as a constant amount of compression is generated, it can be converted into a thrust fixed on the thrust seat 33 and the working head 37, and the compression amount of the tension magazine 34 is set by adjusting the gas red stroke adjusting screw 36 with respect to the cylinder. 1 position and apply a greater than the spring pressure in the air chamber 丨01 Thrust pressure achieved, while adjusting the bottom dead center via the lever stopper portion 311 of position 3 Shu coaxially with the maximum processing capacity control operation head 37, thus achieve the purpose of better-known relatively precisely controlled study M315788.
