[0027] Embodiment 1
[0028] like Figure 1 - Figure 7As shown, a new energy rotor balancing post-processing clamping mechanism is used in a new energy motor rotor balancing machine to solve the problem that when the new energy motor rotor is subjected to balancing test or processing, the clamping force is too large, which will cause the internal deformation of the workpiece, and the clamping force is too small, the product will move and the processing accuracy cannot be ensured; the mechanism includes a base 1, a left clamping assembly 2, a right clamping assembly 3, a driving push plate 4, a small cylinder 5, a large cylinder 6, and a cylinder mounting plate 7. The base 1 includes a table panel 10, a front slide 11, and a rear slide 12; wherein the table panel 10 is a square plate structure as a whole, which is used for bottom support; the front slide 11 and the rear slide 12 are both rectangular columnar structures or U-shaped block structures as a whole, and the two are symmetrically fixed at the front and rear ends above the table panel 10; the front slide 11 and the rear slide 12 are both provided with U-shaped slide grooves on the inner side for the left and right sliding of the left clamping assembly 2 and the right clamping assembly 3. The left clamping assembly 2 and the right clamping assembly 3 are symmetrical structures, and the two are symmetrical and slidably connected to the left and right ends of the base 1, and both are slidably connected between the front slide 11 and the rear slide 12; the left clamping assembly 2 and the right clamping assembly 3 are wedge-shaped connected to the driving push plate 4, so that the driving push plate 4 can push the left clamping assembly 2 and the right clamping assembly 3 away from each other and toward each other for self-locking. The driving push plate 4, the small cylinder 5, and the large cylinder 6 are connected in sequence from front to back; the driving push plate 4 is in the shape of a strip plate, which is sleeved in the middle position inside the base 1; the push and pull force of the large cylinder 6 is respectively greater than the push and pull force of the small cylinder 5; the small cylinder 5 plays a push and pull buffering role, which is similar to the role of a spring, so that the problem of internal deformation or surface damage of the workpiece caused by excessive force when only the large cylinder 6 is used for pushing and pulling can be avoided. The cylinder mounting plate 7 is in the shape of a strip plate, which is fixed at the middle position of the rear side of the base 1 and is used to mount the large cylinder 6 and the small cylinder 5; wherein the large cylinder 6 is fixed at the rear end of the cylinder mounting plate 7; the small cylinder 5 is slidably mounted on the cylinder mounting plate 7, so that the large cylinder 6 can push the small cylinder 5 to move and use it more flexibly. When in use, the large cylinder 6 is extended to drive the small cylinder 5 to retract, and drive the driving push plate 4 to extend relative to the base 1. Since the left clamping assembly 2 and the right clamping assembly 3 are respectively connected to the driving push plate 4 in a wedge shape, the left clamping assembly 2 and the right clamping assembly 3 can slide away from the base 1 in the opposite direction; the large cylinder 6 is retracted to pull the small cylinder 5 out, and at the same time, the small cylinder 5 actively retracts and drives the driving push plate 4 to retract relative to the base 1. Since the left clamping assembly 2 and the right clamping assembly 3 are respectively connected to the driving push plate 4 in a wedge shape, the left clamping assembly 2 and the right clamping assembly 3 can slide towards each other on the base 1 and can be self-locking and fixed.
[0029] In this embodiment, the operating air pressure of the large cylinder 6 and the small cylinder 5 is between 0.3MPa and 0.9MPa. In one implementation, when the large cylinder 6 and the small cylinder 5 both use an air pressure of 0.5Mpa, the large cylinder 6 has a cylinder diameter of 63mm, a cylinder thrust of 1560N, and a pulling force (retracting) of 1400N, and the small cylinder 5 has a cylinder diameter of 25mm, a cylinder thrust of 246N, and a pulling force (retracting) of 206N.
[0030] In this embodiment, the left clamping assembly 2 includes a left slide 21, a left clamping seat 22, and a left clamping plate 23 fixed in sequence from bottom to top; wherein the left slide 21 is a square plate-shaped structure, and its front and rear ends are respectively slidably connected in the U-shaped slide grooves of the front slide 11 and the rear slide 12; the left clamping seat 22 does not limit the specific structural shape, and is used to fix and install the left clamping plate 23.

The right clamping assembly 3 includes a right slide 31, a right clamping seat 32, and a right clamping plate 33 fixed in sequence from bottom to top; the structure of the right clamping assembly 3 is consistent with that of the left clamping assembly 2, and will not be repeated.
[0031] In this embodiment, a left wedge block 24 is integrally formed or welded to the bottom of the left slide 21; the left wedge block 24 includes an integrally arranged left parallel section 241 and a left inclined section 242, wherein the left parallel section 241 is in the shape of a trapezoidal block, which is flush with the end face of the left slide 21, and the left inclined section 242 is in the shape of a parallelogram block, which is arranged at an angle to the end face of the left slide 21. A right wedge block is integrally formed or welded to the bottom of the right slide 31; the structural shape of the right wedge block is consistent with that of the left wedge block 24, or in other words, it is designed to be bilaterally symmetrical on the base 1, which will not be described in detail.

In this way, it is convenient for the large cylinder 6 to push the small cylinder 5 to move, and the use is more flexible and convenient.
[0033] The working principle of this embodiment is as follows: this mechanism adopts the coordinated action of two cylinders to clamp the workpiece; when the large cylinder 6 is pushed out and the small cylinder 5 is retracted, the driving push plate 4 is driven to extend forward relative to the base 1, so that the clamping components on the left and right sides (the left clamping component 2 and the right clamping component 3) slide in the wedge-shaped groove 41 of the driving push plate 4, thereby sliding away from the base 1 and resetting; and when the large cylinder 6 is pulled back, the small cylinder 5 is pulled out by the large cylinder 6 at the same time. At this time, the pulled out small cylinder 5 pulls back again, driving the driving push plate 4 to retract backward relative to the base 1, so that the clamping components on the left and right sides slide in the wedge-shaped groove 41 of the driving push plate 4, thereby sliding towards each other on the base 1, performing a clamping action and self-locking and fixing.
[0034] The beneficial effects of this embodiment are: this mechanism not only ensures sufficient clamping force, but also reduces damage to the clamping surface of the workpiece during the clamping process, and has strong applicability.

[0038] In this embodiment, there are two left clamping pads 25 on the left clamping plate 23, which are arranged front and back; there are two right clamping pads 34 on the right clamping plate 33, which are arranged front and back; the number and structural shape of the two clamping pads are determined by factors such as the number and structural shape of the two clamping plates, and the structural shape of the clamped workpiece, i.e., the new energy rotor.
[0039] The beneficial effect of this embodiment is that by providing the left clamping pad 25 and the right clamping pad 34 , the mechanism can further avoid damage to the clamping surface of the workpiece during the clamping process, and the structural design is more standardized and reasonable.
