In operation, when the positioning cylinder 12 pushes the positioning claws 13 through the slide pin 14 in cooperation with the guide slide hole 19, the positioning claws 13 can be opened outwards around the rotating pin a15 (see the description and the attached drawing 10). After the positioning claws 13 are opened, the positioning cylinder 12 drives the sliding pin 14 to move backwards, the sliding pin 14 can pull the positioning claws 13 through the guide sliding holes 19 to inwards close around the rotating pin A15, and when the two groups of positioning claws 13 are completely closed to a closed state (see the attached figures 7 and 9 of the specification), the curved parts 16 of the two groups of positioning claws 13 are connected to form an annular structure. The inner diameter of the circular ring-shaped structure is consistent with the outer diameter of the ball cage coupler, and when the ball cage coupler works, the ball cage coupler can be clamped and fixed through the bent arc part 16 after the two groups of positioning clamping claws 13 are closed.
Two groups of limit tables 20 are arranged on the upper end surface of the connecting part 18; a limit step 21 is formed between the limit table 20 and the joining part 18 (see the description of fig. 7 and 9). Set up spacing step 21's aim at: so that the during operation, after two sets of location jack catch 13 "closure" fixed the centre gripping of ball cage shaft coupling, people can place ball cage shaft coupling clamp 1 of waiting to assemble on spacing step 21, and spacing step 21 can provide support and location for ball cage shaft coupling clamp 1 this moment, makes its assembly position with on the ball cage shaft coupling be "in opposite directions" setting.
Two sets of limit pins 22 are arranged on the joint part 18 between the two sets of limit tables 20 at intervals (refer to the attached figures 7 and 9 in the specification); the interval between two sets of spacer pins 22 is unanimous with the width that tightens up protruding 2 on the ball cage coupling clamp 1, and when the during operation will treat the ball cage coupling clamp 1 of assembly and place on spacing step 21, but the protruding 2 joint that tighten up of ball cage coupling clamp 1 arrives between the spacer pin 22 that corresponds, so can reach and carry on spacingly through spacer pin 22 to ball cage coupling clamp 1, make the spacer 3 on the ball cage coupling clamp 1 present the state that corresponds each other with collet 49.
A pressing device 49 is arranged on one side of the positioner 48 (see the description, attached figures 4 and 5); the presser 49 comprises a presser head 29, a support 23, a presser cylinder 26, a guide slider 25 and a guide slide bar 28 (see the description and the attached drawing 11); a support 23 is arranged on the frame 4 at one side of the positioner 48; a guide slide block 25 is slidably arranged on the support 23 through a slide groove 24; a pressing cylinder 26 is arranged on a support 23 at one end of the guide slide block 25; the piston rod of the pressing cylinder 26 is connected to the guide slide 25. The pressing cylinder 26 operates to move the guide slider 25 back and forth along the slide groove 24.
A guide sliding rod 28 is arranged on the support 23 at one end of the guide sliding block 25 in a sliding manner through a linear sleeve 27; one end of the guide slide bar 28 is connected with the guide slide block 25 (see the description and the attached figure 11); when the guide slide 25 is operated, the guide slide 28 is driven to move back and forth along the linear sleeve 27.
The other end of the guide slide 28 is provided with a compression head 29 (see figure 11 of the specification). The pressing head 29 is of a cylindrical structure; the end of the pressing head 29 is symmetrically provided with four groups of pressing protrusions 30 (see the description and the attached figure 12). The purpose of thus arranging the pressing head 29 is: so that during operation, the pressing head 29 can press the lap joint part of the ball cage coupler hoop 1 tightly after avoiding the positioning sheet 3 by pressing the gap between the protrusions 30, thus avoiding the problem of 'staggered disconnection' of the lap joint part of the ball cage coupler hoop 1 during operation.
The purpose of providing the pressing projections 30 in four groups is to: when the assembling device works, the assembling device rotates to different angles, so that gaps between the pressing protrusions 30 correspond to the positioning pieces 3 of the ball cage coupler hoops 1 in different specifications, and the assembling device can be conveniently assembled in a shape changing mode.
When the assembling device of the ball cage coupler hoop works, when a conveying line conveys a ball cage coupler to be assembled to the position below the assembling plate 6 to stop acting, the push-pull cylinder 10 on the positioner 48 pushes the movable sliding plate 11 to move a certain distance towards the ball cage coupler, so that the ball cage coupler is arranged inside the positioning clamping jaw 13 in an open state. Then the positioning cylinder 12 moves the sliding pin 14 backwards, and during the backward movement of the sliding pin 14, the positioning claws 13 are pulled through the guide sliding holes 19, so that the positioning claws are inwardly folded around the rotating pin A15 to clamp and fix the ball cage coupler.
After the cage coupler is clamped and fixed by the positioning clamping jaws 13, the ball cage coupler hoop 1 to be assembled is placed on the limiting steps 21 of the positioning clamping jaws 13 from the upper side of the cage coupler and enables the tightening protrusions 2 of the ball cage coupler hoop 1 to be clamped between the corresponding limiting pins 22, and the positioning pieces 3 on the ball cage coupler hoop 1 and the pressing devices 49 are in a corresponding state.
After the ball cage coupling clamp 1 is placed, the pressing cylinder 26 on the pressing device 49 is started to press the overlapped part of the ball cage coupling clamp 1 under the matching of the ball cage coupling through the pressing protrusion 30 on the pressing head 29.
After the presser 49 presses the lap joint part of the ball cage coupler hoop 1, the lifting cylinder 5 drives the assembling plate 6 to move downwards for a section of position, so that the pneumatic clamp 9 on the assembling plate 6 corresponds to the tightening bulge 2 on the ball cage coupler hoop 1.
Then, the pushing cylinder 8 works to drive the corresponding sliding seat 7 and the corresponding pneumatic clamp 9 to move a certain distance towards the ball cage coupler hoop 1; the clamping lug 2 is now located inside the clamping opening 45 of the "open" clamping jaw 36 of the pneumatic clamp 9. Then, an external air supply device introduces high-pressure air of 0.2MPa into the cylinder liner 31 at one end of the pushing piston 38 through an electromagnetic valve, then the pushing piston 38 pushes the pushing piston 38 to move forward under the pushing of the high-pressure air, and in the process of moving forward of the pushing piston 38, the high-pressure air enters the inside of the connecting sleeve 32 through the air guide holes 41 and the air guide grooves 42 to extrude the control sliding sleeve 33 to move forward; the sliding sleeve 33 can move forward under the dual action of the high-pressure gas and the pushing piston 38. During the forward movement of the control sliding sleeve 33, the control sliding sleeve 33 presses one end of the clamping jaw 36 through the control sliding hole 43 and the contact arc 46, so that one ends of the clamping jaws 36 are closed together after overcoming the elastic force of the reset supporting spring 37, and the corresponding tightening protrusions 2 can be clamped through the clamping openings 45 during the mutual closing of the clamping jaws 36, thereby completing the pre-clamping operation of the tightening protrusions 2 (see the attached figure 18 in the specification).
Then, after the pressure of the pneumatic clamp 9 is maintained for 2 seconds, an external air supply device introduces 0.6MPa high-pressure gas into the cylinder liner 31 at one end of the pushing piston 38 through an electromagnetic valve; after the high-pressure gas of 0.6MPa enters the cylinder liner 31, the high-pressure gas further acts on the clamping claw 36 through the pushing piston 38 and the control sliding sleeve 33, so that the clamping claw is further clamped, and the clamping work of the tightening protrusion 2 is completed.
After the clamping claw 36 finishes the 'clamping work' of the tightening protrusion 2, the pneumatic clamp 9 releases pressure through the electromagnetic valve, so that the control sliding sleeve 33 and the pushing piston 38 are rapidly reset under the action of the return spring A34 and the return spring B39; after the control sliding sleeve 33 is reset and is separated from contact with the clamping claws 36, the clamping claws 36 are reset to be opened under the action of the elastic force of the reset supporting springs 37 to be separated from contact with the ball cage coupler hoop 1, then the lifting cylinder 5 drives the assembling plate 6 to reset, the presser 49 resets, the positioning cylinder 12 and the push-pull cylinder 10 on the positioner 48 reset, the positioning claws 13 are reset to be separated from contact with the ball cage coupler after being opened, the assembling device completes the assembling work of the ball cage coupler hoop 1 completely, and the assembling device can enter the next working cycle.
The pneumatic clamp 9 of the application finishes the pre-clamping work of the tightening protrusion 2 by firstly introducing high-pressure gas of 0.2MPa, and then introducing high-pressure gas of 0.6 MPa; the purpose of completing the "clamping work" of the tightening tab 2 is: so that when the pneumatic clamp 9 works in a pre-clamping mode, the clamping claw 36 can firstly force the tightening bulge 2 to slightly deform to clamp and fix the tightening bulge; therefore, even if the problem that the actions of the pneumatic clamps 9 are inconsistent occurs in the process, the problem that the ball cage coupling clamp 1 cannot be assembled due to deformation does not occur. After the pneumatic clamp 9 clamps and fixes the tightening protrusion 2 in a pre-clamping mode, and then 0.6MPa high-pressure gas is introduced to complete clamping, the tightening protrusion 2 is clamped and fixed, so that the problem of deformation caused by inconsistent actions of the pneumatic clamp 9 is solved, and the problem of assembly failure caused by pulling deformation of the hoop 1 when the pneumatic clamp 9 finishes clamping and assembling of the tightening protrusion 2 in one action is solved.
