[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figure 1-2 The embodiments of this utility model include:

[0018] A multi-condition adjustable safety pressure fixture includes the following structure: a base 1, a press frame 2, an infrared grating 3, a lifting cylinder 4, an adjustable pressure valve 5, a lifting sliding guide rod 6, a lifting plate 7, an adjustment component, a pressure head 8, and a carrier 9.

[0019] The press frame is mounted on the base, and an infrared grating is installed on the loading position of the press frame. The safety factor is greatly improved by the infrared grating and the foolproof design of dual buttons for simultaneous two-hand operation.

[0020] Infrared grating dynamic detection can detect foreign object intrusion into the operating area in real time and trigger a millimeter-level emergency stop device.

[0021] Two-hand coordinated start device. The pressing process can only be started by simultaneously triggering two independent buttons with both hands.

[0022] The lifting sliding guide rod is installed inside the press frame, and the lifting plate is slidably connected to the lifting sliding guide rod. The lifting cylinder is installed at the top of the press frame, and the output end of the lifting cylinder is connected to the lifting plate to drive the lifting plate to move up and down along the lifting sliding guide rod. The adjustable pressure valve is connected to the lifting cylinder, which can match and adjust the corresponding pressure value according to the pressure requirements of different products, realize the digital standardization of pressure value, and set the same pressure value through the pressure sensor during production, which significantly improves the pressing yield.

[0023] In a further preferred embodiment, the base is equipped with a switch, an emergency stop button, a power interface 10, etc.

[0024] During assembly, screws are used to fix the lifting cylinder to the press frame. The air pipe connects the adjustable pressure valve and the lifting cylinder. Then, two infrared gratings are installed on the press frame for mutual sensing. Two switch buttons are designed on the base. Both switch buttons need to be pressed by both hands simultaneously to start the pressing operation, avoiding injury from single-handed operation.

[0025] The pressure head is movably positioned on the bottom surface of the lifting plate via an adjustment component, and the carrier is movably positioned on the base below the pressure head assembly via an adjustment component. This allows the pressure head to approach the carrier under the action of the lifting cylinder, which can meet the needs of different pressure heads and facilitate replacement, thereby enabling more efficient and accurate crimping operations.

[0026] The adjustment assembly includes a fixed base 11, a movable connecting groove 12, a sliding connecting slot 13, a sliding connecting block 14, a limit block 15, and a rotating shaft 16.

[0027] A sliding connecting block is provided at the top of the pressure head and at the bottom of the carrier. A fixed seat is provided on the bottom surface of the lifting plate and the top surface of the base. The movable connecting groove and the sliding connecting slot are arranged vertically within the fixed seat, and the bottom of the sliding connecting slot is connected to the movable connecting groove. One end of the sliding connecting slot is a closed structure, and the opening at the other end is located on the side wall of the fixed seat. The diameter of the sliding connecting slot is larger than the diameter of the movable connecting groove, so that the carrier can pass through the movable connecting groove or move back and forth within the movable connecting groove. The sliding connecting slot is movably connected to the sliding connecting block to realize the disassembly and replacement of the pressure head and the carrier.

[0028] One end of the limiting block is rotatably mounted on the fixed seats on both sides of the opening of the sliding connection slot via a rotating shaft, so that the other end of the limiting block blocks the opening of the sliding connection slot, thereby locking or unlocking the connection between the sliding connection block and the fixed seat.

[0029] The working principle of the fixture in this application:

[0030] Based on the product pressure requirements, adjust the adjustable pressure valve and set the corresponding pressure value; select the carrier and pressure head corresponding to the product; horizontally insert the sliding connecting block on the pressure head into the sliding connecting slot of the fixed seat on the bottom of the lifting plate, and the pressure head moves along the movable connecting slot to the target position; after the pressure head is installed, rotate the limit block to block the sliding connecting block, thereby completing the installation of the pressure head; similarly, install the carrier onto the base; place the product into the carrier, press the start switch button with both hands, and the lifting cylinder begins to press down. When the pressure value reaches the preset value, the lifting cylinder drives the lifting plate to rise, so as to remove the pressed product.

[0031] When producing different machine types or products, the above operations can be repeated simply by changing the different pressure heads and carriers, achieving the goal of sharing equipment. During operation, the operation will stop as soon as the infrared grating senses any obstruction, preventing human injury. The fixture as a whole is universal, and by designing adjustment components, different pressure heads and carriers can be changed according to the products being pressed to meet production needs. This greatly reduces the number of presses required, lowers the number of production equipment used, reduces capital investment, and saves costs.

[0032] The beneficial effects of this utility model of a multi-condition adjustable safety pressure fixture are:

[0033] (1) By using an adjustable pressure device, the rapid positioning and precise pressure of parts such as copper sleeves and rivets are achieved, which greatly improves the crimping yield and reduces auxiliary time and rework time by more than 60% compared with the traditional method. The processing cycle of a single piece is shortened simultaneously, which effectively improves production efficiency.

[0034] (2) The modular design with adjustable components supports rapid changeover and adapts to the needs of multi-variety production;

[0035] (3) The integrated two-level safety protection mechanism effectively eliminates the risk of accidental limb entry and reduces the work-related accident rate to 0.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
