Description

Technical Field

[0001] This invention belongs to the field of non-standard automation technology and relates to a rotor clamping indexing mechanism. Background Technology

[0002] In the rotor production process, products often need to be clamped and disassembled. Currently used automated equipment commonly employs pneumatic grippers and pneumatic chucks for positioning and clamping products. However, these clamping methods lack high clamping accuracy and cannot simultaneously achieve high precision, high efficiency, and indexing functions. This makes the pneumatic and electrical circuit layout inconvenient when adding an indexing module, prone to cylinder failure, and unable to meet the requirements of rotor production.

[0003] Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Summary of the Invention

[0004] The purpose of this invention is to provide a rotor clamping indexing mechanism to solve the problems of low rotor clamping efficiency and low accuracy.

[0005] The objective of this invention is achieved through the following technical solution:

[0006] A rotor clamping and indexing mechanism includes a carrying assembly, a rotary indexing table driven by a servo motor mounted on the carrying assembly, a synchronously rotating rotating sleeve mounted on the rotary indexing table, and a clamping assembly disposed within the rotating sleeve; a push rod is disposed below the clamping assembly, and the push rod moves up and down under the drive of the driving mechanism; and

[0007] The clamping assembly includes a spring collet fixed to a rotating sleeve, a spring sleeve that can slide up and down inside the spring collet, and a lower push post for placing the rotor inside the spring collet. The lower push post is fixed to the bearing assembly by a force-bearing rod. A spring support is provided on the spring sleeve located below the spring collet, and a spring is provided on the spring support. The upper end of the spring abuts against the spring collet. The push rod moves upward under the drive of the drive mechanism and pushes the spring sleeve and the spring support upward.

[0008] Furthermore, the upper end of the spring clip has a boss with a frustum structure, and the outer surface of the boss is a guide slope; the spring clip is provided with a channel for placing the lower top column; the spring clip is provided with a plurality of partition grooves axially, and the partition grooves are distributed circumferentially on the spring clip; the partition grooves are connected to the channel and penetrate the upper end face and outer surface of the spring clip.

[0009] Furthermore, the spring support has several springs evenly distributed around its circumference, and the lower end of each spring is fixed to the spring support; the spring support and the spring sleeve are threaded together.

[0010] Furthermore, a dust cover is provided above the rotating sleeve to cover the spring collet.

[0011] Furthermore, the bearing assembly includes a base plate and a fine-tuning plate disposed on the base plate, and the rotary indexing table is disposed on the fine-tuning plate; a first adjustment component for adjusting the position of the base plate is disposed on the outer side of the base plate, and a second adjustment component for adjusting the position of the fine-tuning plate is disposed on the base plate.

[0012] Furthermore, the upper surface of the base plate has a groove, the fine-tuning plate is disposed in the groove, the fine-tuning plate has a waist hole, and the fine-tuning plate is fastened to the base plate by bolts.

[0013] Furthermore, the drive mechanism is mounted on the base plate and includes a cylinder. The cylinder is mounted on a cylinder mounting plate, and the cylinder mounting plate is fixed to the base plate by a cylinder support. The piston of the cylinder is connected to a push rod support plate through a floating joint, and the lower end of the push rod is fixed to the push rod support plate.

[0014] Furthermore, the base plate and the fine-tuning plate are provided with notches for the top rod to pass through vertically.

[0015] Furthermore, the force-bearing rod has an outward protrusion, and the protrusion has a through hole through which the top rod passes vertically.

[0016] The above technical solution has the following advantages: 1. The use of spring collets for rotor positioning and clamping meets the precision requirements of rotor production, ensuring high accuracy; 2. The use of cylinders to drive the spring collets to loosen or tighten saves time and increases efficiency; 3. Equipped with a rotary indexing table, it can achieve indexing function and handle conditions such as dispensing and welding during rotor production; 4. The cylinder and spring collets are not directly connected. When the rotary indexing table drives the spring collets to rotate, the cylinder piston rod will not rotate, avoiding the problem of low lifespan of the cylinder seals due to prolonged piston rod rotation; 5. Since the cylinder and spring collets are not directly connected, the rotation of the rotary indexing table and spring collets has no effect on the cylinder, eliminating difficulties in air and electrical circuit layout; 6. The appropriate spring collets can be easily replaced for different product specifications. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Example

[0029] See Figures 1-5 As shown, a rotor clamping and indexing mechanism includes a bearing assembly 1, on which a rotary indexing table 3 driven by a servo motor 2 is mounted. A synchronously rotating rotating sleeve 4 is mounted on the rotary indexing table 3, and a clamping assembly is disposed within the rotating sleeve 4 for fixing a rotor 6. Two push rods 8 are disposed below the clamping assembly, and the two push rods 8 move up and down under the drive of a drive mechanism 7. Equipped with the rotary indexing table 3, the mechanism can perform indexing functions and can handle conditions such as dispensing and welding during rotor production.

[0030] Combination Figure 6 As shown, the bearing assembly 1 includes a base plate 11 and a fine-tuning plate 12 disposed on the base plate 11, and a rotary indexing table 3 disposed on the fine-tuning plate 12; a first adjustment assembly 13 for adjusting the position of the base plate 11 is disposed on the outer side of the base plate 11, and a second adjustment assembly 14 for adjusting the position of the fine-tuning plate 12 is disposed on the base plate 11.

[0031] Specifically, a groove is provided on the upper surface of the base plate 11, and a fine-tuning plate 12 is disposed within the groove and can move along the X-axis within the groove. A waist hole is provided on the fine-tuning plate 12, and a corresponding bolt hole is provided on the base plate 11. The position of the fine-tuning plate 12 in the groove can be adjusted by the second adjustment assembly 14, and it is locked to the base plate 11 by bolts passing through the waist hole. In this embodiment, the second adjustment assembly 14 includes an adjustment seat 141 fixed on the base plate 11, and an adjustment screw 142 connected to the adjustment seat 141. The adjustment screw 142 can rotate on the adjustment seat 141, and one end of the adjustment screw 142 is threadedly connected to the fine-tuning plate 12. On-site operators can rotate the adjustment screw 142 to fine-tune the position of the fine-tuning plate 12. Similarly, the first adjustment assembly 13 includes an adjustment seat 131 fixed on an external bracket, and an adjustment screw 132 connected to the adjustment seat 131. The adjustment screw 132 can rotate on the adjustment seat 131, and one end of the adjustment screw 142 is threadedly connected to the base plate 11. On-site operators can rotate the adjusting screw 132 to finely adjust the relative position of the base plate 11.

[0032] In this embodiment, the clamping assembly includes a spring collet 101 fixed on the rotating sleeve 4. A spring sleeve 102, capable of sliding up and down, is disposed within the spring collet 101. A lower top post 10, for placing the rotor 6, is also disposed within the spring collet 101. The lower top post 10 is fixed to the bearing assembly 1 by a force-bearing rod 9. A spring support 103 is disposed on the spring sleeve 102 located below the spring collet 101. The spring support 103 can be a round nut, threadedly engaged with the spring sleeve 102 to fix the position of the spring support 103 relative to the spring sleeve 102.

[0033] A spring 104 is provided on the spring support 103, and the upper end of the spring 104 abuts against the spring collet 101. In this embodiment, there are six springs 104, evenly distributed on the spring support 103, and the lower end of the spring 104 is fixed to the spring support 103. The push rod 8 moves upward under the drive of the drive mechanism 7 and pushes the spring sleeve 102 and the spring support 103 upward. At this time, the spring 104 is compressed, and the upper end of the spring sleeve 102 is exposed outside the spring collet 101.

[0034] like Figure 7 As shown, the upper end of the spring sleeve 102 has a frustum-shaped boss 1021, and the outer surface of the boss 1021 is a guide ramp 1022. A channel 1023 for placing the lower top column is provided inside the spring sleeve 102. Several partition grooves 1024 are axially arranged on the spring sleeve 102, and these partition grooves 1024 are circumferentially distributed on the spring sleeve 102. The partition grooves 1024 communicate with the channel 1023 and penetrate the upper end face and outer surface of the spring sleeve 102.

[0035] The spring sleeve 102 with the above structure is used in conjunction with the spring collet 101. When the spring sleeve 102 is pushed upward by the push rod 8, the boss 1021 on the spring sleeve 102 will be exposed above the spring collet 101. At this time, the guide ramp 1022 is not squeezed by the spring collet 101, the boss 1021 returns to its original shape, and the upper end of the channel 1023 opens, making it convenient for personnel to remove the rotor from the channel 1023 or place the rotor on the lower push post 10 in the channel 1023. When the push rod 8 moves downward, under the action of the spring 104, the spring sleeve 102 moves downward as a whole, causing the boss 1021 to fall into the spring collet 101. Under the influence of the guide ramp 1022, the boss 1021 fixes the rotor in the channel 1023.

[0036] In this embodiment, a dust cover 5 is provided above the rotating sleeve 4 to cover the spring clamp. This serves two purposes: aesthetics and preventing dust from entering the rotating sleeve 4 and affecting the clamping assembly's ability to fix the rotor.

[0037] The drive mechanism 7 is located below the base plate 11, so the push rod 8 needs to pass vertically through the base plate 11 and the fine-tuning plate 12. In this embodiment, notches are provided on the base plate 11 and the fine-tuning plate 12 for the push rod 8 to pass vertically.

[0038] In this embodiment, the force-bearing rod 9 has an outward protrusion, and the protrusion has a through hole through which the top rod 8 passes vertically. The force-bearing rod 9 is fixed on the fine-tuning plate 12 and does not rotate with the rotary indexing table 3.

[0039] The drive mechanism 7 includes a cylinder 71, which is mounted on a cylinder mounting plate 72. The cylinder mounting plate 72 is fixed to the base plate 11 by a cylinder support 73. The piston of the cylinder 71 is connected to a push rod support plate 75 via a floating joint 74. The lower end of the push rod 8 is fixed to the push rod support plate 75. In this embodiment, there are two push rods 8, which are distributed at 180° on both sides of the force-bearing rod 9.

[0040] When cylinder 71 is in the retracted state, the push rod 8 is not in contact with the clamping assembly. At this time, cylinder 71 is not directly connected to the spring collet. Therefore, when the rotary indexing table 3 drives the spring collet 101 to rotate, the piston rod of cylinder 71 will not rotate with it, avoiding the problem of low lifespan of the cylinder seals caused by prolonged piston rod rotation. At the same time, the rotation of the rotary indexing table 3 and the spring collet 101 has no effect on cylinder 71, and there are no problems with the layout of air and electrical circuits during use.

[0041] Cylinder 71 is activated, pushing push rod 8 upward. The upper end of push rod 8 first contacts spring support 103 and / or spring collet 102, pushing spring collet 102 upward until the boss 1021 on spring collet 102 is exposed above spring chuck 101. The operator places the new rotor on lower push column 10, cylinder 71 retracts, causing push rod 8 to completely disengage from the clamping assembly. Under the reset action of spring 104, spring collet 102 moves downward, and the boss 1021 re-enters spring chuck 101. During this process, the boss 1021 is squeezed by spring chuck 101, fixing the rotor.

[0042] This embodiment uses spring collets to position and clamp the rotor, meeting the high precision requirements of rotor production. Simultaneously, the opening of the spring collet 102 can accommodate rotor products of different specifications. The spring collets are bolted to the rotating sleeve 4; replacement is simple, requiring only the removal of the dust cover 5 and unscrewing the bolts for easy replacement of the corresponding spring collet. Operation utilizes a cylinder to drive the spring collets to loosen or tighten, saving time and increasing efficiency.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
