DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0029] Reference Figure 3 , Figure 4 and Figure 5 A jig clamping mechanism provided in an example of the utility model is arranged on a cleaning machine. The cleaning machine includes a support seat 100 and a turntable 110 rotatably connected to the support seat 100. The jig clamping mechanism includes two clamps 120, and the two clamps 120 are respectively used to clamp two sides of a jig 270. The clamp 120 includes a clamping block 130, a movable rod 140, a spring 150 sleeved on the movable rod 140, and a stopper 160 arranged at one end of the movable rod 140. The clamping block 130 is connected to one end of the movable rod 140 away from the stopper 160. The movable rod 140 passes through the turntable 110. The clamping block 130 is located above the turntable 110, the spring 150 is located below the turntable 110, and the spring 150 is abutted between the turntable 110 and the stopper 160.

[0030] When an upward external force is applied to the stopper 160 , the stopper 160 , the movable rod 140 and the clamping block 130 move upward together, the spring 150 is compressed, and a space for inserting the jig 270 is formed between the clamping block 130 and the rotating disk 110 .

[0031] When the external force applied to the stopper 160 disappears, the stopper 160 moves downward under the elastic force of the spring 150 to drive the movable rod 140 and the clamping block 130 to move downward, so that the clamping block 130 presses the jig 270 on the turntable 110, and the two clamping blocks 130 clamp the two sides of the jig 270, so that the bottom plate and the cover plate of the jig 270 press the parts to prevent the parts from detaching. At the same time, the sealing element on the cover plate of the jig 270 can press the parts, and then the holes of the parts can be sealed to prevent water from entering the holes of the parts.

[0032] Furthermore, the fixture clamping mechanism also includes a lifting assembly 170, which is disposed on the support seat 100. The lifting assembly 170 is located below the turntable 110. The lifting assembly 170 is used to lift the two blocks 160, thereby improving the clamping efficiency of the fixture 270 and reducing labor intensity.

[0033] Specifically, the jacking assembly 170 includes a mounting frame 180, a driving member 190 installed on the mounting frame 180, a jacking connecting rod 210 arranged at the output end of the driving member 190, and two jacking blocks 200 respectively arranged at both ends of the jacking connecting rod 210. The mounting frame 180 is arranged on the outside of the support seat 100, and the jacking connecting rod 210 is arranged horizontally. When the turntable 110 rotates and drives the two clamps 120 to move directly above the jacking assembly 170, the two jacking blocks 200 are respectively arranged under the two stoppers 160, and the driving member 190 drives the jacking connecting rod 210 to rise, and the jacking connecting rod 210 drives the jacking connecting rod 210 and the two jacking blocks 200 to rise. The two jacking blocks 200 are respectively used to lift the two stoppers 160. Only one power member is needed to lift the two clamping blocks 130 at the same time, thereby simplifying the structure of the equipment and saving the manufacturing cost of the equipment.

[0034] In some preferred embodiments, the driving member 190 includes a cylinder, which has a simple structure, fast operation, and is easy to install.

[0035] It should be noted that the driving member 190 may also be a device capable of achieving extension and retraction, such as a hydraulic cylinder or an electric cylinder.

[0036] Furthermore, the clamp block 130 is an inverted L-shaped structure, and a slot for accommodating the insertion of one side of the jig 270 is formed between the clamp block 130 of the inverted L-shaped structure and the turntable 110. Moreover, the inner side of the clamp block 130 is used to limit the side of the jig 270, thereby improving the positioning accuracy of the jig 270 and allowing the clamp block 130 to accurately clamp the side of the jig 270.

[0037] Furthermore, a limiting plate 220 is arranged between the two clamping blocks 130, and the limiting plate 220 is fixed on the turntable 110. The two clamping blocks 130 and the limiting plate 220 are respectively used to limit the three adjacent sides of the fixture 270, thereby further improving the positioning accuracy of the fixture 270 and ensuring that the insertion position of each fixture 270 is consistent.

[0038] In order to prevent the fixture 270 from being thrown out during the rotation of the turntable 110 , the limiting plate 220 is disposed on the outer side of the turntable 110 .

[0039] It should be noted that the outer side of the turntable 110 refers to the side of the fixture that is away from the rotation center of the turntable 110 .

[0040] When the turntable 110 rotates, the fixture 270 is subjected to centrifugal force, and the limiting plate 220 can prevent the fixture 270 from being thrown out.

[0041] In some preferred embodiments, a waterproof cover 230 is provided on the outer periphery of the cylinder to prevent the cleaning liquid from being sprayed onto the cylinder during cleaning, thereby increasing the service life of the cylinder.

[0042] Furthermore, the mounting frame 180 includes a crossbeam 240, a lifting and adjusting plate 250 arranged at one end of the crossbeam 240, and a mounting plate 260 connected to the lifting and adjusting plate 250. The other end of the crossbeam 240 is fixed on the support seat 100. The mounting plate 260 is used to install the cylinder, and the lifting and adjusting plate 250 is used to adjust the horizontal height of the mounting plate 260. Specifically, the lifting and adjusting plate 250 is provided with a plurality of threaded holes in sequence from top to bottom, and the adjusting mounting plate 260 is connected to the threaded holes by bolts. When it is necessary to adjust the installation height of the cylinder, the bolts on the adjusting mounting plate 260 are first unscrewed from the original threaded holes, and then the bolts on the adjusting mounting plate 260 are screwed into another threaded hole located above or below the original threaded hole. Then, the installation height of the cylinder can be adjusted, thereby being able to adapt to jigs 270 of different thicknesses and improving the applicability of the mechanism.

[0043] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
