[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a pneumatic clamping tool for a motor end cover, including a base plate 1, on which a positioning mechanism 2, a clamping mechanism 3 and a supporting mechanism 4 are arranged, the positioning mechanism 2 is used to preliminarily position the end cover 7, the clamping mechanism 3 includes a plurality of clamping components 31, each clamping component 31 is used to clamp each process pressure point of the end cover 7, and the supporting mechanism 4 includes a plurality of supporting components 41, each supporting component 41 is used to support each suspended part inside the end cover 7.

[0020] like Figure 2 As shown, the clamping assembly 31 includes a lever cylinder 311 and a pressure claw 312. The lever cylinder 311 is installed on the base plate 1. The driving end of the lever cylinder 311 is connected to the pressure claw 312. The pressure claw 312 is adapted to the process pressure point of the end cover 7. The lever cylinder 311 is used to drive the pressure claw 312 to clamp the end cover 7.

[0021] Specifically, the pneumatic clamping tooling of the motor end cover is composed of a positioning mechanism 2, a clamping mechanism 3 and a supporting mechanism 4. The end cover 7 is fixed to the base through the positioning mechanism 2. The process pressure points and the internal suspended parts of the end cover 7 correspond to the clamping mechanism 3 and the supporting mechanism 4 respectively. Among them, the clamping mechanism 3 includes four clamping components 31. The clamping component 31 is composed of a lever cylinder 311 and a pressing claw 312. The lever cylinder 311 drives the pressing claw 312 to clamp each process pressure point of the end cover 7, and then the internal suspended part of the end cover 7 is supported by the supporting component 41.

[0022] The above structure uses the lever cylinder 311 to clamp and the support assembly 41 to support, which increases the clamping and supporting area of ​​the end cover 7, making the process safe and reliable during the processing of the end cover 7, and can effectively avoid the occurrence of tool vibration and deformation of the end cover 7.

[0023] like Figure 2 As shown, in one embodiment, the support assembly 41 of the motor end cover pneumatic pressing tooling includes a support cylinder 411, the support end of the support cylinder 411 is adapted to the suspended portion inside the end cover 7, and the support cylinder 411 is used to support the end cover 7.

[0024] Specifically, five supporting cylinders 411 may be provided to support the suspended portion inside the end cover 7 . When the lever cylinder 311 drives the pressing claw 312 to press the end cover 7 , the five supporting cylinders 411 support the five suspended portions inside the end cover 7 respectively.

[0025] This arrangement facilitates compensating for the pressure of the positioning mechanism 2 on the end cover 7, increases the supporting area of ​​the end cover 7, and prevents deformation of the end cover 7 during the processing.

[0026] like Figure 2 As shown, in one embodiment, the positioning mechanism 2 of the motor end cover pneumatic pressing tooling includes a positioning plate 21, a positioning pin 22, a plurality of No. 1 support rods 23 and a plurality of No. 2 support rods 24. The positioning plate 21 and the positioning pin 22 cooperate with each other to fix the end cover 7. Each No. 1 support rod 23 is used to support the middle part of the end cover 7. The No. 2 support rod 24 is used to cooperate with the pressing claw 312 to support and press the end cover 7.

[0027] Specifically, the positioning plate 21 and the positioning pin 22 fix the end cover 7. When the lever cylinder 311 drives the pressing claw 312 to press the end cover 7, the three No. 1 support rods 23 provide support force to the center position of the end cover 7, and the four No. 2 support rods 24 are arranged directly below the four pressing claws 312 to provide support force to the four process pressure points of the end cover 7.

[0028] This arrangement increases the support area of ​​the end cover 7 and prevents the end cover 7 from being deformed during the processing.

[0029] like Figure 2 As shown, in one of the embodiments, a pressure-maintaining valve 5 is further provided on the bottom plate 1 of the pneumatic pressing fixture for the motor end cover, and the pressure-maintaining valve 5 is respectively connected in series with the positioning mechanism 2, the supporting assembly 41 and the lever cylinder 311.

[0030] Specifically, the pressure-maintaining valve 5 provides gas to the No. 1 gas path of the No. 1 support rod 23 and the No. 2 gas path of the No. 2 support rod 24, and also provides gas to the support cylinder 411 and the lever cylinder 311. This arrangement facilitates the lever cylinder 311 to provide pressure to the end cover 7, so that the support cylinder 411, the No. 1 gas path and the No. 2 gas path provide stable supporting force to the end cover 7.

[0031] like Figure 2 As shown, in one of the embodiments, an accumulator 6 is also provided on the base plate 1 of the pneumatic clamping tooling of the motor end cover. The accumulator 6 is connected to the pressure maintaining valve 5. The accumulator 6 is used to store gas and perform gas compensation on the support assembly 41 and the lever cylinder 311.

[0032] Specifically, the accumulator 6 can store gas, and when the gas circuits provided by the pressure-maintaining valve 5 to the No. 1 gas circuit, the No. 2 gas circuit, the lever cylinder 311 and the support cylinder 411 are unstable, the accumulator 6 performs gas compensation.

[0033] This arrangement serves as a compensating gas for the No. 1 gas circuit, the No. 2 gas circuit, the lever cylinder 311 and the support cylinder 411 .

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
