It has strong applicability, and the mechanism is ingenious in structure, simple in operation, can effectively save costs, and is easy to use.

[0004] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0005] A clamping mechanism for post-balancing processing of a new energy rotor includes a base, a left clamping assembly, and a right clamping assembly. The left and right clamping assemblies are slidably connected to both ends of the base. The mechanism also includes a drive push plate, a small cylinder, and a large cylinder connected sequentially from front to back. The drive push plate is sleeved with the base, and the left and right clamping assemblies are wedge-shaped connected to the drive push plate. When the large cylinder extends, it drives the small cylinder to retract, and drives the drive push plate to extend relative to the base, causing the left and right clamping assemblies to slide away from each other on the base. When the large cylinder retracts, the small cylinder is pulled out, and the small cylinder retracts, driving the drive push plate to retract relative to the base, causing the left and right clamping assemblies to slide towards each other on the base.

[0007] According to one aspect of the present invention, the wedge groove is a V-shaped groove, and the left wedge block includes an integral left parallel section and a left inclined section. The left parallel section is flush with the end face of the left slide plate, and the left inclined section is set at an angle to the end face of the left slide plate.

[0008] According to one aspect of the present invention, the left clamping assembly is provided with a left clamping pad, and the right clamping assembly is provided with a right clamping pad, both the left clamping pad and the right clamping pad being made of plastic or rubber.

[0009] According to one aspect of the present invention, the left clamping assembly includes a left sliding plate, a left clamping fixing seat, and a left clamping plate fixed from bottom to top, and the right clamping assembly includes a right sliding plate, a right clamping fixing seat, and a right clamping plate fixed from bottom to top.

[0015] Advantages of this invention: This mechanism uses a dual-cylinder operation to clamp the workpiece; when the large cylinder extends and the small cylinder retracts, the clamping components on both sides reset; when the large cylinder retracts, the small cylinder is simultaneously pulled out by the large cylinder, and then the pulled-out small cylinder retracts again, causing the clamping components on both sides to perform a clamping action by sliding in the wedge groove of the drive push plate. At this time, the two clamping components, namely the left and right clamping components, are self-locking and fixed.

[0027] Embodiment one

[0028] As shown in Figures 1-7, a clamping mechanism for post-balancing processing of a new energy rotor is used in a new energy motor rotor balancing machine. It addresses the problems of excessive clamping force causing internal deformation of the workpiece during balancing tests or processing of new energy motor rotors, and insufficient clamping force causing product movement and compromising processing accuracy. The mechanism includes a base 1, a left clamping assembly 2, a right clamping assembly 3, a drive push plate 4, a small cylinder 5, a large cylinder 6, and a cylinder mounting plate 7. The base 1 includes a platform 10, a front slide 11, and a rear slide 12. The platform 10 is generally square and provides bottom support. The front and rear slides 11 and 12 are both rectangular columnar structures or U-shaped block structures, symmetrically fixed at the front and rear ends above the platform 10. Both the front and rear slides 11 and 12 have U-shaped grooves on their inner surfaces for the left and right sliding of the left and right clamping assemblies 2 and 3. The left clamping assembly 2 and the right clamping assembly 3 are symmetrical in structure, symmetrically and slidably connected to the left and right ends of the base 1, respectively. Both are slidably connected between the front slide block 11 and the rear slide block 12. The left clamping assembly 2 and the right clamping assembly 3 are wedge-shaped connected to the drive push plate 4, which facilitates the drive push plate 4 to push the left clamping assembly 2 and the right clamping assembly 3 away from each other and close together for self-locking. The drive push plate 4, the small cylinder 5, and the large cylinder 6 are connected in sequence from front to back. The drive push plate 4 is a strip-shaped plate and is fitted inside the middle of the base 1. The pushing and pulling force of the large cylinder 6 is greater than that of the small cylinder 5. The small cylinder 5 acts as a push and pull buffer, similar to the function of a spring, thus avoiding 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. The cylinder mounting plate 7 is strip-shaped and fixed in the middle of the rear side of the base 1. It is used to mount the large cylinder 6 and the small cylinder 5. The large cylinder 6 is fixed to the rear end of the cylinder mounting plate 7. The small cylinder 5 is slidably mounted on the cylinder mounting plate 7, which facilitates the large cylinder 6 to drive the small cylinder 5 and makes it more flexible to use. In use, the large cylinder 6 extends, causing the small cylinder 5 to retract and the drive push plate 4 to extend relative to the base 1. Since the left clamping component 2 and the right clamping component 3 are wedge-shaped connected to the drive push plate 4, the left clamping component 2 and the right clamping component 3 can slide away from each other on the base 1. When the large cylinder 6 retracts, the small cylinder 5 is pulled out. At the same time, the small cylinder 5 actively retracts and causes the drive push plate 4 to retract relative to the base 1. Since the left clamping component 2 and the right clamping component 3 are wedge-shaped connected to the drive push plate 4, the left clamping component 2 and the right clamping component 3 can slide towards each other on the base 1 and can be self-locked.

[0029] In this embodiment, the operating air pressure of the large air cylinder 6 and the small air cylinder 5 is between 0.3MPa and 0.9MPa; in one implementation, when both the large air cylinder 6 and the small air cylinder 5 use an air pressure of 0.5MPa, the large air cylinder 6 has a cylinder diameter of 63mm, a cylinder thrust of 1560N, and a pulling force (retraction) of 1400N, and the small air cylinder 5 has a cylinder diameter of 25mm, a cylinder thrust of 246N, and a pulling force (retraction) of 206N.

[0030] In this embodiment, the left clamping assembly 2 includes a left sliding plate 21, a left clamping fixing seat 22, and a left clamping plate 23, which are fixed from bottom to top. The left sliding plate 21 has a square plate structure, and its front and rear ends are slidably connected to the U-shaped grooves of the front slide seat 11 and the rear slide seat 12, respectively. The left clamping fixing seat 22 is not limited to a specific structural shape, and it is used to fix and install the left clamping plate 23. The left clamping fixing seat 22 can be two integrally inverted T-shaped plates, symmetrically fixed at the front and rear ends of the left sliding plate 21. The left clamping plate 23 is integrally U-shaped, and its structural shape is adapted to the structural shape of the clamped workpiece, i.e., the rotor of the new energy motor. The right clamping assembly 3 includes a right sliding plate 31, a right clamping fixing seat 32, and a right clamping plate 33, which are fixed from bottom to top. The structure of the right clamping assembly 3 is the same as that of the left clamping assembly 2, and will not be described again.

[0031] In this embodiment, a left wedge block 24 is integrally formed or welded to the bottom of the left sliding plate 21. The left wedge block 24 includes an integrally formed left parallel section 241 and a left inclined section 242. The left parallel section 241 is trapezoidal and flush with the end face of the left sliding plate 21, while the left inclined section 242 is parallelogram-shaped and angled to the end face of the left sliding plate 21. A right wedge block is integrally formed or welded to the bottom of the right sliding plate 31. The structure of the right wedge block is consistent with that of the left wedge block 24, or in other words, they are symmetrically designed on the base 1. The drive push plate 4 is provided with a wedge groove 41, which is a V-shaped groove. The left wedge block 24 and the right wedge block are slidably connected to the wedge groove 41, and the left wedge block 24 and the right wedge block are located within the two sides of the V-shape of the V-groove.

[0032] In this embodiment, the mechanism further includes a linear guide rail and a cylinder sliding plate 8. The linear guide rail is fixed on the cylinder mounting plate 7, and the cylinder sliding plate 8 is slidably connected to the linear guide rail via a slider. The small cylinder 5 is fixed on the cylinder sliding plate 8, and the extended end of the large cylinder 6 is fixed to the cylinder sliding plate 8. This facilitates the large cylinder 6 in driving the small cylinder 5, making it more flexible and convenient to use.

[0033] The working principle of this embodiment is as follows: This mechanism uses the coordinated action of two cylinders to clamp the workpiece; when the large cylinder 6 extends and the small cylinder 5 retracts, it drives the drive push plate 4 to extend forward relative to the base 1, so that the clamping components on the left and right sides (left clamping component 2 and right clamping component 3) slide in the wedge groove 41 of the drive push plate 4, thereby sliding away from the base 1 and resetting; when the large cylinder 6 pulls back, the small cylinder 5 is simultaneously pulled out by the large cylinder 6. At this time, the pulled-out small cylinder 5 pulls back again, driving the drive 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 groove 41 of the drive push plate 4, thereby sliding towards each other on the base 1, performing a clamping action and self-locking.

[0034] The beneficial effects of this embodiment are as follows: This mechanism not only ensures sufficient clamping force, but also reduces damage to the workpiece clamping surface during the clamping process. It has strong applicability. At the same time, the mechanism has a compact structure, simple operation, can effectively save costs, and is easy to use.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that this mechanism also includes a left clamping pad 25 and a right clamping pad 34, wherein the left clamping pad 25 is fixed on the left clamping plate 23 and the right clamping pad 34 is fixed on the right clamping plate 33.

[0037] In this embodiment, both the left clamping pad 25 and the right clamping pad 34 are made of plastic or rubber, which ensures insulation and also protects the workpiece clamping surface, preventing damage to the workpiece clamping surface during the clamping process.

[0038] In this embodiment, there are two left clamping pads 25 on the left clamping plate 23, arranged front to back; there are two right clamping pads 34 on the right clamping plate 33, arranged front to back; the number and structure of the two types of clamping pads are determined by factors such as the number and structure of the two types of clamping plates and the structure of the clamped workpiece, i.e., the new energy rotor.

[0039] The beneficial effects of this embodiment are as follows: by setting the left clamping pad 25 and the right clamping pad 34, this mechanism can further avoid damage to the workpiece clamping surface during the clamping process, and the structural design is more standardized and reasonable.

[0040] Example 3

[0041] The difference between this embodiment and Embodiment 1 is that this mechanism also includes a floating joint 9, a connecting rod 13, a front push plate 14, and a rear push plate 15; wherein the floating joint 9 is connected to the drive push plate 4, one end of the connecting rod 13 is connected to the floating joint 9 and the other end is connected to the small cylinder 5, the front push plate 14 and the rear push plate 15 are both fixed on the cylinder sliding plate 8, and the large cylinder 6 is connected to the rear push plate 15.

[0042] In this embodiment, the floating joint 9 is snapped into the rear end of the drive push plate 4; the connecting rod 13 passes through or is sleeved inside the front push plate 14, with the front end of the connecting rod 13 fixed to the floating joint 9 and the rear end fixed to the extension shaft of the small cylinder 5; the front push plate 14 is U-shaped; the extension shaft of the large cylinder 6 is connected and fixed to the rear push plate 15 by bolts, and the rear push plate 15 is plate-shaped or block-shaped.

[0043] In this embodiment, the front push plate 14 is located behind the drive push plate 4, and is positioned between the drive push plate 4 and the small cylinder 5; the height of the front push plate 14 is greater than the height of the drive push plate 4. The front push plate 14 can limit the drive push plate 4; the rear push plate 15 facilitates the large cylinder 6 to push and pull the small cylinder 5.

[0044] The advantages of this embodiment are as follows: by setting the floating joint 9, the movement is more flexible; by setting the front push plate 14, it can limit the driving push plate 4 or the entire clamping and resetting process, making the operation more stable. At the same time, the overall structure of this mechanism is compact and has a wide range of applications.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, combinations, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
