Beneficial effects

[0017] In the present utility model, the bushing installation module and the bleed bolt installation module are integrated on the same device. Meanwhile, the provision of the material rack facilitates the access to bushings and bleed bolts during the operation of the bushing installation module and the bleed bolt installation module, thereby enabling the installation steps of the two parts, namely the bushing and the bleed bolt, to be completed on the same device during the piston caliper assembly process. This layout reduces the transfer time between devices and significantly improves the overall assembly efficiency.

[0018] In the present utility model, both the bushing installation module and the bleed bolt installation module adopt an automated installation method, reducing the complexity and labor intensity of manual operations. Automated installation can precisely control the alignment installation of the bushing and the through-hole and the tightening force of the bleed bolt, effectively avoiding installation problems caused by human factors and improving the installation quality of the bushing and the bleed bolt.

[0019] In the present utility model, the guide rod not only provides guidance for the straight-line movement of the press head but also increases the stability and reliability of the entire installation process. Through the matching of the mating block and the mating space, high-precision positioning can be achieved during the bushing installation process, which helps to reduce installation errors and ensures as much as possible that the bushing can be accurately installed at the specified position, improving the assembly accuracy and consistency of the product.

[0020] In the present utility model, the conical mating block and the mating space enable the press head to quickly and smoothly enter the mating space under the push of the bushing installation cylinder, and the two can be evenly stressed when they come into contact, avoiding wear problems caused by excessive local stress. At the same time, the conical mating block and the mating space enable the position calibration of the press head to be synchronized during the gradual mating process, effectively reducing the errors caused by deviations and ensuring the installation accuracy of the bushing as much as possible.

[0021] In the present utility model, the setting of the diameter difference between the first region and the second region enables the mating end to preliminarily position the bushing during the installation process, preventing the bushing from moving unrestrictedly during the installation process. Further, the provision of the bushing limiting portion further prevents the bushing from falling off the press head during the installation process.

[0022] In the utility model, since the floating plunger is a flexible limiting element, it can reduce the risk of damage to the bushing during installation; at the same time, since the diameter of the bushing matches the inner diameter of the through hole of the caliper body, the diameter of the first area where the floating plunger is located when it is extended is larger than the inner diameter of the through hole, so as to prevent the bushing from falling off the pressure head during installation; when the bushing reaches the through hole, the floating plunger will automatically shrink under the constraint of the inner diameter of the through hole, so that the floating plunger retracts into the plunger installation hole; this automatic shrinkage mechanism ensures that the bushing can be installed smoothly, and there is no need to set up an additional structure to release the limiting function of the bushing limiting part. After the bushing is installed, it will receive a limiting force from the caliper body; at this time, the floating plunger is still in a contracted state and is inside the bushing during the process of resetting the pressure head. At this time, the force that the floating plunger can exert is limited and insufficient to bring the floating plunger out of the through hole, which can avoid the bushing limiting part accidentally bringing the bushing out after the installation is completed as much as possible.

[0023] In the utility model, the guide rod is able to move through the setting of the compression spring, and under the action of the compression spring, it abuts against the pressure head to exert a certain force on the pressure head, thereby reducing the deviation and shaking during the installation process as much as possible, which is conducive to achieving high-precision assembly; at the same time, it avoids damage caused by hard contact between the guide rod and the pressure head; it can also realize the automatic resetting function of the guide rod. After completing an installation operation, the compression spring can automatically reset the guide rod to the initial position without manual adjustment, which greatly simplifies the operation process and improves work efficiency.

[0024] In the utility model, the bushing installation movable block is movably connected to the bushing installation frame through the cooperation of the slide rail and the slider, thereby improving the stability of the bushing installation movable block and the pressure head during movement and improving the installation effect.

[0025] In the utility model, the arrangement of the stabilizing bracket and the stabilizing cylinder ensures the smooth progress of the installation process and improves the overall stability and reliability of the equipment.

[0026] In the utility model, the bleed bolt installation module realizes the automated installation of the bleed bolt through the bolt installation mechanism, including the steps of positioning and tightening the bolt; this automated operation greatly improves production efficiency, reduces the time and cost of manual installation, and also reduces the possibility of human error.

[0027] In the utility model, the tightening rod is driven to rotate by a rotating motor, thereby realizing efficient tightening of the bleed bolt, making the bolt firmly tightened to a specified torque in a short time as much as possible, thereby improving the installation efficiency.

[0028] In the present utility model, through the arrangement of the air slip ring and the first air flow channel, the second air flow channel and the third air flow channel in the rotating head, the tightening device has the function of testing the air passage gas conduction effect inside the test pliers body; before putting the air release bolt into the rotating head for tightening, the bolt installation cylinder can drive the air flow outlet of the third air flow channel of the rotating head to align with the air release outlet of the pliers body, and then fill gas into the air flow inlet of the first air flow channel through an external air pipe or other devices, so as to test the conduction effect of the pliers body.

[0029] In the present utility model, when the pliers body is fixed on the second fixed seat, the auxiliary fixing device can provide further limiting force to improve the stability of the pliers body during the installation process. Description of the Drawings

[0052] In the present utility model, the two ends of the pressing head 41 are respectively a connection end 411 and a fitting end 412, and the connection end 411 is connected to the piston rod of the bushing installation cylinder 42; the fitting block 43 is provided at the fitting end 412 and is located at the end of the fitting end 412; both the fitting block 43 and the fitting space 52 are in an inverted conical shape, and the bottom surface of the conical fitting block 43 is connected to the end of the fitting end 412; both the pressing head 41 and the through hole 102 are in a cylindrical shape; the central axes of the fitting space 52, the through hole 102, and the bushing 104 are on the same straight line, and when the bushing 104 is installed, the central axes of the pressing head 41, the fitting block 43, the fitting space 52, the through hole 102, and the bushing 104 are on the same straight line; the conical fitting block 43 and the fitting space 52 enable the pressing head 41 to quickly and smoothly enter the fitting space 52 under the push of the bushing installation cylinder 42, and the two can be evenly stressed when they come into contact, avoiding wear problems caused by excessive local stress; at the same time, the conical fitting block 43 and the fitting space 52 can synchronously calibrate the position of the pressing head 41 during the gradual fitting process, effectively reducing the error caused by deviation and ensuring the installation precision of the bushing 104 as much as possible.

[0053] In the utility model, the mating end 412 includes a first area 413 and a second area 414, the second area 414 is located on the side of the first area 413 close to the connecting end 411, and the first area 413 is located between the second area 414 and the mating block 43; the diameter of the first area 413 corresponds to the inner diameter of the bushing 104, and the diameter at the second area 414 is larger than the diameter at the first area 413 and the inner diameter of the bushing 104; a bushing limiting portion 44 for limiting the position of the bushing 104 is provided on the first area 413, and the bushing 104 is located between the bushing limiting portion 44 and the second area 414; the diameter difference between the first area 413 and the second area 414 is set so that during the installation process, the mating end 412 can preliminarily position the bushing 104 to prevent the bushing 104 from moving without restriction during the installation process; further, the setting of the bushing limiting portion 44 further prevents the bushing 104 from falling off the pressure head 41 during the installation process.
