[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-6, the utility model provides a technical solution: a clamping and positioning structure for assembling a washing machine water level sensor, including a clamping and positioning structure main body 1, characterized in that an assembly positioning seat 2 is provided on the clamping and positioning structure main body 1, and a limiting boss 201 of an integral structure is provided above the assembly positioning seat 2. A through hole penetrating up and down is opened on the assembly positioning seat 2 at the position of the limiting boss 201, and a support seat 4 is longitudinally movably clamped through the through hole in the limiting boss 201. Clamping mechanisms 3 are evenly spaced on the side surface of the limiting boss 201. The assembly positioning seat 2 is of a square structure, and a bottom plate 6 is screwed and fixed to the bottom of the assembly positioning seat 2. And a mounting plate 601 is clamped and screwed and fixed in the middle of the bottom plate 6. Limiting holes 203 are also spaced on the assembly positioning seat 2, and a second limiting rod 8 is inserted and fastened at the position of the limiting hole 203 on the assembly positioning seat 2. The lower part of the clamping mechanism 3 is movably clamped in the limiting hole 203, and the lower part of the clamping mechanism 3 is movably penetrated by the second limiting rod 8. This structure forms a support structure of the clamping and positioning structure main body 1 through the assembly positioning seat 2, so that the washing machine water level sensor has a stable and reliable support structure during assembly. The bottom plate 6 is used for connecting and processing the assembly positioning seat 2 to the operating table. The clamping mechanism 3 is used for clamping the outer shell of the washing machine water level sensor. And the clamping mechanism 3 can move smoothly under the common limitation of the second limiting rod 8 and the limiting hole 203 to realize the clamping movement of the clamping mechanism 3. And during the movement of the clamping mechanism 3, the outer shell of the washing machine water level sensor is clamped by the clamping fastener 302. A connecting seat 202 of an integral structure is provided on the outer side of the limiting boss 201, and a clamping driving cylinder 5 is horizontally installed between the connecting seat 202 and the clamping mechanism 3. And the clamping driving cylinder 5 is arranged in parallel with the second limiting rod 8. This structure limits the lifting of the support seat 4 through the limiting boss 201. The limiting boss 201 can also install the clamping driving cylinder 5 through the connecting seat 202 to ensure that the clamping driving cylinder 5 has the same specification as the lifting driving cylinder 7. And the inner sides of the clamping mechanisms 3 are respectively connected with first fixing shells 301. A second fixing shell 303 is clamped on the side surface of the first fixing shell 301. And a limiting plate 304 is clamped and fastened between the first fixing shell 301 and the second fixing shell 303. And movable guide rods 307 are evenly spaced and movably penetrated on the limiting plate 304. A groove is opened at the bottom of the support seat 4, and a lifting driving cylinder 7 is screwed and fixed in the groove of the support seat 4. And the bottom of the lifting driving cylinder 7 is installed on the lifting driving cylinder 7 through bolts. The cross section of the support seat 4 is an inverted T-shaped structure, and first limiting rods 401 are evenly spaced and movably penetrated on the side surface of the bottom of the support seat 4. The upper ends of the first limiting rods 401 are fixed to the limiting boss 201 through a threaded structure, and the lower ends of the first limiting rods 401 are clamped and matched with the mounting plate 601. This structure enables the support seat 4 to be lifted and adjusted through the lifting driving cylinder 7 to adjust the height of the bottom support position when clamping the outer shell of the washing machine water level sensor. The support seat 4 is stably installed through the first limiting rods 401, and the first limiting rods 401 limit the lifting of the support seat 4.Both ends of the movable guide rod 307 are respectively provided with a clamping fastener 302 and a movable sleeve 305, and the clamping fastener 302 movably penetrates through the second fixed shell 303, so that the clamping mechanism 3 forms a movable clamping and positioning structure through the clamping fastener 302. The movable guide rod 307 and the clamping fastener 302 are of an integral structure, and the movable guide rod 307 is movably inserted into the movable sleeve 305. A fastening spring 308 is movably sleeved on the movable guide rod 307 between the limit plate 304 and the clamping fastener 302, and both ends of the fastening spring 308 are respectively engaged with the limit plate 304 and the clamping fastener 302. This structure enables the clamping fastener 302 to move through the movable guide rod 307. The second fixed shell 303 and the second fixed shell 303 are respectively used for the movable limit of the clamping fastener 302 and the movable guide rod 307. At the same time, when the clamping fastener 302 moves, the fastening spring 308 is compressed. The fastening spring 308 realizes the clamping and positioning of the outer shell of the washing machine water level sensor by the clamping fastener 302 through the rebounding force. The movable sleeve 305 and the first fixed shell 301 are of an integral structure, and a return spring 306 is movably engaged in the movable sleeve 305, and the return spring 306 is engaged with the end of the movable guide rod 307. This structure enables the movable guide rod 307 to also compress the return spring 306 through the limit of the movable sleeve 305 when moving. The return spring 306 enables the auxiliary movable guide rod 307 to return when the clamping fastener 302 releases the clamped workpiece.,
[0021] Working principle: When using the clamping and positioning structure for assembling the washing machine water level sensor, first, the main body 1 of the clamping and positioning structure is installed and positioned at the bottom through the bottom plate 6, so that the assembling positioning seat 2 is stably installed. When assembling the washing machine water level sensor, adjust the height position of the support seat 4 according to the depth of the outer shell of the washing machine water level sensor. Let the lifting drive cylinder 7 drive the support seat 4 to lift under the installation and positioning of the mounting plate 601. The limit boss 201 and the first limit rod 401 are respectively used for the movable limit of the support seat 4. When assembling the washing machine water level sensor, place the outer shell of the washing machine water level sensor on the support seat 4, and then start the clamping drive cylinder 5 to make the clamping mechanism 3 move towards the middle part. The clamping mechanism 3 is movably limited relative to the support seat 4 through the limit hole 203 and the second limit rod 8. The support seat 4 is used for the fixation between the clamping drive cylinder 5, the limit boss 201 and the clamping mechanism 3. The first fixed shell 301 fixes the second fixed shell 303 to the clamping mechanism 3. When the clamping fastener 302 contacts the outer shell of the washing machine water level sensor, the clamping fastener 302 moves towards the inside of the second fixed shell 303 through the movable guide rod 307. The limit plate 304 and the movable sleeve 305 are used for the movable limit of the movable guide rod 307. At the same time, the clamping fastener 302 and the movable guide rod 307 respectively compress the fastening spring 308 and the return spring 306. Through the rebounding force of the spring, the clamping fastener 302 tightly clamps the irregularly shaped outer shell, thus completing a series of operations.
