[0021] In the embodiment: locking assembly 4 includes hexagonal frame 41, hexagonal frame 41 is fixedly connected with the outer circumference of support 2, the inner wall of hexagonal frame 41 is inserted with fixed frame 42, the one end of fixed frame 42 close to assembly mould 3 is provided with recess, and the inner wall of recess is fixedly connected with rubber pad 43, the center of fixed frame 42 is provided with storage cavity 44, and the inner wall of storage cavity 44 is fixedly connected with partition plate 45, the front and rear sides of partition plate 45 are fixedly connected with limit spring 46, and the one side of connecting frame 47 close to support 2 is fixedly connected with bayonet 48, and the one side of connecting frame 47 away from partition plate 45 is fixedly connected with pressing block 49.

[0022] Specifically, the rubber pad 43 is in contact with the outer circumference of the assembly mold 3, and the friction coefficient between the fixed frame 42 and the assembly mold 3 can be increased by the rubber pad 43 to improve the limiting effect of the fixed frame 42 on the assembly mold 3 in the locked state.

[0023] Specifically, the side of the limit spring 46 away from the partition plate 45 is fixedly connected with the inner wall of the connecting frame 47.

[0024] In the embodiment: the universal limit spring 46 can constrain the position of the connecting frame 47 to ensure the stability of the connecting frame 47 in the locked state.

[0025] Specifically, the bayonet 48 is slidably connected with the inner wall of the storage cavity 44, the bayonet 48 is inserted with the inner wall of the hexagonal frame 41, and the inserted end of the bayonet 48 is inversely tapered. By the bayonet 48, the position of the fixed frame 42 can be locked in the state of being inserted into the hexagonal frame 41.

[0026] In the embodiment: the pressing block 49 is slidably connected with the inner wall of the storage cavity 44, and the pressing block 49 penetrates the side surface of the fixed frame 42.

[0027] In the embodiment: the pressing block 49 can be pressed by the staff to change the position state of the connecting frame 47.

[0028] Specifically, the reinforcing assembly 5 comprises a horizontal plate 51 fixedly connected with the inner wall of the base 1, an arc-shaped frame 52 fixedly connected with the upper surface of the horizontal plate 51, a supporting plate 53 fixedly connected with the side surface of the arc-shaped frame 52, and a reinforcing rib 54 fixedly connected with the joint of the horizontal plate 51 and the arc-shaped frame 52. The reinforcing rib 54 can increase the structural strength of the joint of the horizontal plate 51 and the arc-shaped frame 52, so as to improve the firmness of the arc-shaped frame 52.

[0029] Specifically, the number of the arc-shaped frames 52 is two, and the two arc-shaped frames 52 are symmetrically arranged about the bracket 2. The arc-shaped frames 52 are fixedly connected with the outer arc surface of the bracket 2, and the supporting plates 53 are fixedly connected with the outer arc surface of the arc-shaped frames 52.

[0030] In the embodiment, the upper end arc surface of the bracket 2 can be supported by the cooperation of the arc-shaped frames 52 and the supporting plates 53, so as to ensure the stability of the upper end of the bracket 2.

[0031] Working principle: when processing, the worker puts the rubber ring on the workpiece, and then puts the workpiece into the assembly mold 3. After the workpiece is placed, the workpiece is pushed towards the assembly mold 3, and the rubber ring is moved into the assembly mold 3. When the rubber ring contacts the assembly mold 3, the rubber ring is clamped into the groove reserved in the workpiece under the shielding of the assembly mold 3. After the operation is completed, the assembled workpiece can be taken out. When replacing the assembly mold 3, the two pressing blocks 49 are pressed, the pressing blocks 49 extrude the limiting springs 46 through the cooperation of the connecting frames 47, the limiting springs 46 are extruded and deformed, the connecting frames 47 pull the pin 48 while extruding the limiting springs 46, the pin 48 is pulled out of the hexagonal frame 41 and loses the locking of the fixed frame 42. Then the fixed frame 42 is pulled away from the assembly mold 3, the rubber gasket 43 is pulled, and the locking of the assembly mold 3 is lost. After the assembly mold 3 is unlocked, the new assembly mold 3 can be inserted into the bracket 2, and the fixed frame 42 is inserted into the hexagonal frame 41 and locked. Through the setting of the locking assembly 4, the efficiency of the worker in replacing the mold is improved, and the problem of difficult control of the fastening range of the bolt, which easily leads to the deformation of the assembly mold 3, is reduced, and the convenience of replacing the mold is further improved.

[0032] After fixing the bracket 2, the arc frame 52 is aligned with the outer arc surface of the bracket 2, and the horizontal plate 51 is pushed downward. The horizontal plate 51 pulls the arc frame 52 and the support plate 53. During the movement, the arc frame 52 and the support plate 53 gradually approach the outer arc surface of the bracket 2. When the arc frame 52 and the support plate 53 both reach the surface of the bracket 2, the horizontal plate 51 is fixed inside the base 1 with the help of bolts and other fasteners. Then the reinforcement component 5 can reinforce the upper end of the bracket 2. By setting the reinforcement component 5, the upper structure of the bracket 2 can be reinforced, thereby further improving the stability of the upper end of the bracket 2.
