[0003] At present, double cylinders are widely used in the fields of automated production lines, assembly lines, hardware, mechanical fixtures, etc. When a workpiece needs to be pushed at a workstation, the existing double cylinder does not have a stroke adjustment device. After the double cylinder fixes the workpiece, the stroke range of the workpiece cannot be adjusted according to the needs of the production line. Different types of double cylinders need to be installed for different stroke ranges. At the same time, when producing workpieces of different specifications, the pushing distance of the double cylinder at the same position is also different, which makes it necessary to disassemble and replace different types of double cylinders.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

By arranging a limit groove capable of adjusting the limit plate on the cylinder body and opening a through hole on the limit plate, the end sides of the push rod arranged on the baffle plate are set on both sides of the limit plate, thereby controlling the stroke of the cylinder and preventing the cylinder of different specifications from being disassembled and installed again due to work needs after the cylinder is installed.
[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a double-stroke regulating cylinder, including a cylinder body, and two piston rods slidably arranged on one side of the cylinder body, a top plate is arranged on the side of the two piston rods away from the cylinder body, a mounting plate is arranged on the top of the top plate, a top rod parallel to the piston rod is arranged on the mounting plate, a plurality of limit grooves are arrayed on both sides of the cylinder body, and a limit plate corresponding to the top rod is detachable in the limit groove.
[0007] Preferably, a through hole corresponding to the push rod is formed on the limiting plate, and a baffle is detachably connected to the end of the push rod away from the mounting plate.
[0008] Preferably, support plates are provided at both end sides of the cylinder body close to the top plate, and shaft holes corresponding to the top rods are opened on the support plates.
[0009] Preferably, corresponding first threaded holes are formed on the top plate and the mounting plate, and screws are arranged in the first threaded holes.
[0010] Preferably, a fixing plate is provided on the end side of the push rod, corresponding second threaded holes are provided on the fixing plate and the mounting plate, corresponding third threaded holes are provided on the limiting plate and the side wall of the limiting groove, and screws are provided in the second threaded hole and the third threaded hole.

[0012] The utility model has the following beneficial effects:
[0013] According to the distance the workpiece needs to be pushed, the limit plate is installed in the limit groove. When the working environment required by the cylinder is that the cylinder is extended to the farthest distance and the return distance is less than the extension distance of the cylinder, the push rod is moved away from the limit hole. The cylinder stroke can be controlled by installing the baffle on the side of the limit plate close to the top plate. On the contrary, when the working environment required by the cylinder is less than the farthest distance the cylinder is extended to, the cylinder stroke can be controlled by adjusting the limit plate to the corresponding position, inserting the push rod into the through hole, and installing the baffle on the side of the limit plate away from the top plate, thereby preventing the cylinder from being disassembled and installed again due to work needs after the cylinder is installed.

[0019] When it is necessary to control the operation of the cylinder, the installation position of the limit plate 7 is adjusted, and then the limit plate 7 is fixed by the screw 13. The end of the push rod 5 is slid to the side of the limit plate 7 as needed, and then the baffle 9 is fixed to the push rod 5 by the screw 13 to control the stroke trajectory of the cylinder. When the required working environment of the cylinder is that the cylinder is extended to the farthest distance and the return distance is less than the extension distance of the cylinder, the push rod 5 is moved away from the limit hole 18, and the cylinder stroke can be controlled by installing the baffle 9 on the side of the limit plate 7 close to the top plate 3. On the contrary, when the required working environment of the cylinder is less than the farthest distance extended by the cylinder, the limit plate 7 is adjusted to the corresponding position, the push rod 5 is inserted into the through hole 8, and the baffle 9 is installed on the side of the limit plate 7 away from the top plate 3. The cylinder stroke can be controlled to prevent errors from occurring after the cylinder is installed and disassembled and adjusted again due to work needs.
[0020] In summary:
[0021] According to the required distance of pushing the workpiece, the limit plate 7 is installed in the limit groove 6. When the required working environment of the cylinder is that the cylinder is extended to the farthest distance and the return distance is less than the extension distance of the cylinder, the push rod 5 is moved away from the limit hole 18. The cylinder stroke can be controlled by installing the baffle 9 on the side of the limit plate 7 close to the top plate 3. On the contrary, when the required working environment of the cylinder is less than the farthest distance extended to the cylinder, the cylinder stroke can be controlled by adjusting the limit plate 7 to the corresponding position, inserting the push rod 5 into the through hole 8, and installing the baffle 9 on the side of the limit plate 7 away from the top plate 3. This prevents the cylinder from being disassembled and installed again due to work needs after the cylinder is installed.
