The technical scheme has the following technical effects:

[0005] The present application is characterized in that the caliper rectangular ring assembly device is provided with a mounting gap and an air passage, so that when the operator needs to install the rectangular ring into the rectangular ring mounting groove inside the caliper, the rectangular ring can be first sleeved on the pressing rod, the rectangular ring is arranged around the mounting gap, the inner side wall of the rectangular ring faces the mounting gap to form a closed periphery of the mounting gap, the rectangular ring, the rod body and the cover plate jointly form a cavity in communication with the air passage, the air pump assembly draws air from the air passage to extract the air in the cavity to form a negative pressure environment in the cavity, and the rectangular ring elastically deforms in the direction of the cavity under the action of atmospheric pressure to shrink into the mounting gap; then the end of the pressing rod provided with the cover plate is inserted into the caliper, and during the insertion process, the negative pressure environment in the cavity can ensure that the rectangular ring is located in the mounting gap as a whole and will not hinder or affect the insertion of the pressing rod and the caliper, when the insertion of the pressing rod and the caliper is completed, the mounting gap is aligned with the rectangular ring mounting groove inside the caliper, at this time, the air pump assembly ventilates the air into the air passage, the air enters the cavity through the air passage to destroy the negative pressure environment in the cavity, and the rectangular ring resets outside the mounting gap, the rectangular ring popped out of the mounting gap is just flatly clamped into the rectangular ring mounting groove, and finally the pressing rod can be taken out.

[0040] Example one:

[0041] A caliper rectangular ring assembly device, such as Figures 1 to 8As shown, including the pressure rod 300 and air pump assembly 400, the pressure rod 300 includes a rod body 310 and a cover plate 320 fixed on one end of the rod body 310, the rod body 310 is provided with a gas passage 311 penetrating through the rod body 310, and the cover plate 320 is installed on the rod body 310 through the mounting column 321 to form a mounting gap 330 between the cover plate 320 and the end of the rod body 310, the mounting gap 330 is communicated with one end of the gas passage 311 for accommodating the rectangular ring 200. The air pump assembly 400 is communicated with the other end of the gas passage 311 away from the mounting gap 330, and the air pump assembly 400 can exhaust or ventilate the mounting gap 330 through the gas passage 311.

[0042] The caliper rectangular ring assembly device provided with the mounting gap 330 and the gas passage 311, when the operator needs to install the rectangular ring 200 into the rectangular ring mounting groove 110 inside the caliper 100, the rectangular ring 200 can be sleeved on the pressure rod 300 first, so that the rectangular ring 200 is arranged around the mounting gap 330, the inner side wall of the rectangular ring 200 faces the mounting gap 330 to form a closed space on the circumference of the mounting gap 330, and the rectangular ring 200, the rod body 310 and the cover plate 320 jointly form a cavity 340 communicated with the gas passage 311, then the air pump assembly 400 exhausts the gas in the gas passage 311, the gas passage 311 exhausts the gas in the cavity 340 to form a negative pressure environment in the cavity 340, and the rectangular ring 200 made of flexible material is elastically deformed in the direction of the cavity 340 under the action of atmospheric pressure to shrink into the mounting gap 330. Figure 3 As shown, during the insertion process of the caliper 100, the negative pressure environment in the cavity 340 can ensure that the rectangular ring 200 is located in the mounting gap 330 as a whole and cannot extend out of the mounting gap 330 to hinder or affect the insertion of the pressure rod 300 and the caliper 100, when the pressure rod 300 and the caliper 100 are inserted, the mounting gap 330 is aligned with the rectangular ring mounting groove 110 in the caliper 100, at this time, the air pump assembly 400 ventilates the gas into the gas passage 311, and the gas enters the cavity 340 through the gas passage 311 to destroy the negative pressure environment in the cavity 340. Figure 4 As shown, the rectangular ring 200 will reset outside the mounting gap 330, and the rectangular ring 200 popped out of the mounting gap 330 will be flatly clamped into the rectangular ring mounting groove 110, and finally the pressure rod 300 can be taken out of the caliper 100. The whole installation process is simple and convenient, and the operator does not need to take the rectangular ring 200 to manually press it into the rectangular ring mounting groove 110, which avoids the rectangular ring 200 falling into the recess in the caliper 100 during manual installation, and avoids the problem that the rectangular ring 200 cannot be pressed flatly due to misalignment with the rectangular ring mounting groove 110, reduces the assembly difficulty, saves the assembly time, and improves the assembly efficiency.

[0043] In the embodiment, the caliper rectangular ring assembly device further comprises a pushing assembly 500, a transmission assembly 600 and a driving assembly 700, the transmission assembly 600 is connected between the pushing assembly 500 and the driving assembly 700 to drive between the driving assembly 700 and the pushing assembly 500, the driving assembly 700 drives the pushing assembly 500 to move through the transmission assembly 600, so that the pushing assembly 500 can switch between the retracted position in the installation gap 330 and the pushing position out of the installation gap 330, as shown in Figure 6 When the pushing assembly 500 is in the retracted position, the rectangular ring 200 retracted in the installation gap 330 can be retracted, as shown in Figure 8 When the pushing assembly 500 moves from the retracted position to the pushing position, the rectangular ring 200 can be pushed out of the installation gap 330, so that when the amount of gas introduced into the cavity 340 by the air pump assembly 400 can release the negative pressure environment, the pushing assembly 500 can push the rectangular ring 200 outwards to assist the elastic reset of the rectangular ring 200 retracted in the installation gap 330, shorten the ventilation time and improve the assembly efficiency. Of course, it can be understood that in another embodiment, the caliper rectangular ring assembly device can not include the pushing assembly, the transmission assembly and the driving assembly.

[0044] As shown in Figure 2 In the embodiment, the pushing assembly 500 comprises a plurality of rotating shafts 510, the rotating shafts 510 are arranged through the rod body 310, the central axis of the rotating shaft 510 is parallel to the central axis of the pressing rod 300, the rotating shafts 510 are arranged around the central axis of the rod body 310, one end of the rotating shaft 510 is provided with a swing lever 520 located in the installation gap 330, the end of the swing lever 520 is fixed on the rotating shaft 510, the other end of the rotating shaft 510 is connected with the transmission assembly 600, when the transmission assembly 600 drives the rotating shaft 510 to rotate, the swing lever 520 rotates with the rotating shaft 510 to make the end of the swing lever 520 extend or retract from the installation gap 330. By arranging the pushing assembly 500 to rotate the swing lever 520 through the rotating shaft 510, and arranging the rotating shaft 510 through the rod body 310, the rotating shaft 510 can be hidden and protected, at the same time, the plurality of rotating shafts 510 arranged around the central axis of the rod body 310 can make the swing lever 520 arranged at the end of each rotating shaft 510 rotate with the rotating shaft 510 to push the rectangular ring 200 in all directions at the same time, so that the rectangular ring 200 can be reset better when reset to the installation gap 330, and then the rectangular ring 200 can be flatly embedded into the rectangular ring installation groove 110. Preferably, the included angle formed by any two adjacent rotating shafts 510 and the central axis of the pressing rod 300 is the same, so that the stress on the circumferential side of the rectangular ring 200 is more uniform.

When the drive assembly 700 drives the turntable 610 to rotate, all positioning posts 611 fixed on the turntable 610 rotate together with the turntable 610. As the positioning posts 611 slide from one end of the groove 621 to the other end, ... Figure 5 and Figure 7 As shown, the corresponding transmission component 620 is driven to rotate, and all transmission components 620 rotate simultaneously, thereby driving all rotating shafts 510 to rotate synchronously. A single turntable 610 and drive structure can achieve the synchronous rotation of all rotating shafts 510, eliminating the need for multiple drive structures to drive each rotating shaft 510 separately, which greatly reduces the size and production cost of the caliper rectangular ring assembly device.

[0046] When the operator needs to install the rectangular ring 200 into the rectangular ring installation slot 110 inside the caliper 100, the driving assembly 700 drives the rotating shaft 510 to rotate through the transmission assembly 600, so that all the swing rods 520 are located in the installation gap 330, at this time, the swing rods 520 are in the retracted state, after the operator sets the rectangular ring 200 on the pressing rod 300, the air pump assembly 400 pumps the air in the air passage 311 to extract the gas in the cavity 340, so as to form a negative pressure environment in the cavity 340, and the rectangular ring 200 is elastically deformed under the action of atmospheric pressure to shrink into the installation gap 330, and the swing rods 520 in the retracted state will not hinder the rectangular ring 200 shrinking into the installation gap 330, then the end of the pressing rod 300 provided with the cover plate 320 is inserted into the caliper 100, the installation gap 330 is aligned with the rectangular ring installation slot 110 in the caliper 100, then the air pump assembly 400 ventilates the air passage 311, and the gas enters the cavity 340 through the air passage 311 to destroy the negative pressure environment in the cavity 340, and the rectangular ring 200 will reset outside the installation gap 330, at the same time, the driving assembly 700 drives the rotating disc 610 to rotate, the rotating disc 610 drives the transmission member 620 to rotate through the positioning column 611, and then drives all the rotating shafts 510 to rotate synchronously, so that the swing rods 520 connected to the ends of the rotating shafts 510 rotate together, all the swing rods 520 are opened outward through rotation, and the swing rods 520 apply an outward opening force to the rectangular ring 200 to reset, so as to assist the rectangular ring 200 to open to be flat and clamped into the rectangular ring installation slot 110, and after the rectangular ring 200 is installed, the pressing rod 300 can be taken out.

[0047] In the embodiment, the end of the rod body 310 towards the cover plate 320 is further provided with a stop protrusion 350, the stop protrusion 350 has a first stop portion 351 and a second stop portion 352, the first stop portion 351 and the second stop portion 352 are respectively located on both sides of the swing rod 520, when the swing rod 520 rotates to the avoiding position, the swing rod 520 abuts against the first stop portion 351 to prevent the swing rod 520 from continuing to rotate, when the swing rod 520 rotates to the pushing position, the swing rod 520 abuts against the second stop portion 352 to prevent the swing rod 520 from continuing to rotate, that is, the first stop portion 351 and the second stop portion 352 limit the stroke of the swing rod 520 by abutting against the swing rod 520, so as to ensure that the swing rod 520 can stably avoid or push the rectangular ring 200, and avoid excessive rotation of the swing rod 520. Preferably, the stop protrusion 350 is arranged in one-to-one correspondence with the swing rod 520, and a deformation gap 360 is formed between adjacent two stop protrusions 350, so that when the rectangular ring 200 deforms into the installation gap 330 under the action of the negative pressure environment of the cavity 340, the deformation gap 360 can reserve a large space for the deformation of the rectangular ring 200, so as to facilitate the rectangular ring 200 to deform into the installation gap 330 at a high speed.
