Description

Technical Field

[0001] The invention relates to the technical field of clamps, in particular to a flexible clamping device for a bearing retainer assembly machine. Background Art

[0002] The bearing cage, also known as the bearing cage or roller cage, is a component inside the bearing. Its main function is to fix and keep the rolling elements in the bearing in the correct position to maintain the stability and accuracy of the bearing during operation. The cage can guide the rolling elements to be evenly distributed on the track, prevent the rolling elements from contacting each other, reduce friction and wear, and facilitate the installation and removal of bearings. The bearing cage assembly machine is a mechanical equipment specially used to assemble bearing cages. When punching the bearing cage, the bearing cage is usually loaded and unloaded by a robot or manually, and the loading and unloading method is through a robot;

[0024] See also Figure 1 It should be noted that when the upper die 7 and the lower die 5 are close to each other to press the workpiece, in order to improve work efficiency, the lower die 5 has five groups of structures with the same structure. When the first group of lower dies 5 completes the work, the first motor 6 works according to the set forming work, and the power gear with it rotates, and the rack meshing with it is displaced, thereby driving the sliding table 4 to slide on the substrate 2, and automatically sending the second group of lower dies 5 to the bottom of the upper die 7, thereby improving work efficiency.

[0025] The sliding table 4 can slide through the support frame 3, which can facilitate the sliding of the sliding table 4 on the base plate 2 and increase the operating space of the sliding table 4. Five groups of lower molds 5 with the same structure are evenly arranged on the top of the sliding table 4, and a first motor 6 is installed on the front outer wall of the base plate 2. An upper mold 7 is arranged directly above one group of lower molds 5, and a hydraulic punch 8 is connected to the top of the upper mold 7. The hydraulic punch 8 is an existing structure, which drives the upper mold 7 to punch downward and cooperates with the lower mold 5 to press the workpiece. The hydraulic punch 8 is connected to the bottom of the machine body 9, and the machine body 9 is installed on the top rear side of the workbench 1. A downward pressing cross bar 10 is installed on the outer wall of the hydraulic punch 8. The outer end of the downward pressing cross bar 10 is connected to a positioning plate 11. A positioning box 12 is arranged directly below the positioning plate 11. Connecting rods 14 are connected to both sides of the positioning box 12, and a clamping plate 15 is connected to the connecting rod 14. Two groups of clamping plates 15 are arranged above the lower mold 5 on the far right;

[0026] See also Figure 1 It should be noted that when the upper die 7 and the lower die 5 cooperate with each other to press the workpiece, the two sets of clamps 15 clamp the workpiece. The curved surface of the clamp 15 that contacts the workpiece is connected with a rubber sheet to protect the workpiece from being damaged due to excessive clamping force. The positioning plate 11 moves up and down with the downward pressing cross bar 10 as the hydraulic punch 8 works, that is, the positioning plate 11 is movably inserted into the positioning box 12, and the connecting rods 14 connected on both sides thereof are controlled to realize the opening and closing of the two sets of clamps 15, so as to realize the clamping of the press-fitted workpiece.

[0027] The positioning box 12 is installed on the rotating component 13, and the rotating component 13 is set on the support frame 3. A collecting trough 16 is set on the top of the workbench 1, and the collecting trough 16 is set on the right side of the machine body 9. A control switch 17 is installed on the front outer wall of the workbench 1. This control switch 17 is electrically connected to the first motor 6, the machine body 9, the second motor 135 and the hydraulic punch 8 respectively.

[0028] Likewise, see Figure 1 After the two groups of clamping plates 15 clamp the workpiece, the rotating assembly 13 drives the clamped workpiece to be placed in the collecting trough 16, which is convenient for the staff to collect and sort.

[0029] Among them, preferably, a positioning groove 121 is provided on the top of the positioning box 12, and the position and size of the positioning groove 121 are adapted to the positioning plate 11, and two groups of slides 122 with the same structure are movably inserted on the outer walls on both sides of the positioning box 12, and the front end outer wall of the slide 122 is connected to one end of the connecting rod 14, and the wolf slides 122 move closer to and further away from each other, thereby driving the two groups of connecting rods 14 to move closer to and further away from each other, so that the two groups of clamps 15 can perform clamping and lowering operations, and a straight groove 123 is provided on the outer wall of the rear side of the positioning box 12, and a pushing cross bar 124 is connected to the inner cavity of the straight groove 123, and the inner end of the pushing cross bar 124 is connected to the outer wall of the slide 122 on the left side, and the pushing cross bar 124 can drive the slide 122 on the left side to achieve lateral movement alone.

[0030] Preferably, the slide plate 122 is a rectangular plate body with an inclined surface, and the slide plate 122 is provided with a mounting groove 126 adapted to the connecting rod 14, two groups of lateral slides 125 with the same structure are symmetrically arranged on the outer walls on both sides of the slide plate 122, and a lateral slide groove matching the lateral slide 125 is provided on the inner wall of the positioning box 12, so as to facilitate the slide plate 122 to slide in the positioning box 12, and a bottom slide bar 127 is installed at the bottom of the slide plate 122, and a spring 128 is connected to the inner end of the bottom slide bar 127, and the spring 128 provides a stable restoring force to the slide plate 122, which is convenient for the recovery of the slide plate 122, and also provides a stable removal force to the two groups of splints 15, and a bottom slide groove matching the bottom slide bar 127 is provided on the positioning box 12, and the inner wall of one end of the bottom slide groove is connected to the outer end of the spring 128.

[0031] Preferably, the positioning plate 11 includes a pressing block 111 with inclined surfaces on both sides of the bottom, and fixing plates 112 are installed on the outer walls on both sides of the top of the pressing block 111, and the fixing plates 112 are connected by screws 113, and the rear fixing plate 112 is connected to the end of the downward pressure cross bar 10.

[0032] Please join Figure 1-Figure 5 The two sets of inclined surfaces at the bottom of the positioning plate 11 correspond to the inclined surfaces of the slide plate 122. When the positioning plate 11 moves down into the positioning box 12 along with the hydraulic punch 8, the two sets of inclined surfaces contact each other. When the positioning plate 11 continues to be pressed down, the two sets of slide plates 122 move to both sides, thereby driving the two sets of connecting rods 14 to move away from each other. At this time, the upper mold 7 and the lower mold 5 contact each other to press the workpiece. After the press-fitting, the upper mold 7 and the lower mold 5 move away from each other and separate, and the positioning plate 11 is retracted upward. At this time, under the action of the two sets of springs 128, the two sets of slide plates 122 approach each other, so that the two sets of connecting rods 14 drive the two sets of clamping plates 15 to approach each other to clamp the pressed workpiece.

[0033] Preferably, the rotating assembly 13 includes an auxiliary turntable 131, and a positioning box 12 is installed on the top of the auxiliary turntable 131, and an active turntable 132 is engaged with the outer wall of the auxiliary turntable 131, and the active turntable 132 rotates to drive the auxiliary turntable 131 to rotate, and the active turntable 132 is connected to a second motor 135 through a connecting shaft, and the second motor 135 is installed at the bottom of the support frame 3, and a semicircular groove 133 is opened on the auxiliary turntable 131, and the position of the semicircular groove 133 is close to the position of the positioning box 12, and the inner cavity of the semicircular groove 133 is connected to a push vertical rod 134, and the bottom of the push vertical rod 134 is installed on the top of the support frame 3.

[0034] For clarification, please refer to Figure 2 When the positioning plate 11 moves up, the two groups of clamping plates 15 clamp the workpiece. In order to remove the workpiece after the press-fitting and maintain the continuity of the press-fitting operation, the second motor 135 is started at this time. According to the set stroke, the auxiliary rotary disc 133 is driven to rotate through the active rotary disc 132, and the positioning box 12 rotates accordingly. During the rotation process, the semicircular groove 133 also rotates accordingly, and the pushing vertical rod 134 remains stationary at this time. When the positioning box 12 rotates to a certain angle (that is, the two groups of clamping plates 15 move the workpiece to the position of the collecting groove 16), the pushing vertical rod 134 and the pushing cross bar 124 contact each other. At this time, because the pushing vertical rod 134 is stationary, the pushing cross bar 124 in contact with it will move in the straight groove 123, thereby driving the left side slide plate 122 to move outward. At this time, the two groups of clamping plates 15 put down the workpiece and drop it into the collecting groove 16 for collection and sorting. After that, the second motor 135 works in the opposite direction to bring the two groups of clamping plates 15 to their original positions.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
