[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 as well as Figure 2 The present invention provides a positioning and assembly device for a thermostat housing, including an assembly table 7, a front cover positioning groove 2 on the assembly table 7, a centering structure 1 for clamping the front cover in the front cover positioning groove 2, and automatic positioning structures 4 on the other two sides of the front cover positioning groove 2.

[0026] The centering structure 1 includes a bidirectional lead screw 13, which is located in the adjustment port 17 and is also connected to the adjustment knob 15. The adjustment knob 15 is located on one side of the assembly table 7. The rotation direction of the bidirectional lead screw 13 can be controlled by adjusting the knob 15. The adjustment port 17 is located at the bottom of the front cover positioning groove 2. A first side positioning plate 11 and a second side positioning plate 16 are also provided on both sides of the front cover positioning groove 2. A first lead screw nut 12 is provided at the bottom of the first side positioning plate 11, and a second lead screw nut 14 is provided at the bottom of the second side positioning plate 16. The first lead screw nut 12 and the second lead screw nut 14 are respectively connected to both sides of the bidirectional lead screw 13.

[0027] In practical use, first, insert the thermostat front cover into the front cover positioning groove 2. At the same time, the automatic positioning structure 4 automatically positions the two sides of the thermostat front cover. Then, rotate the adjustment knob 15, which drives the bidirectional lead screw 13 to rotate. The first lead screw nut 12 and the second lead screw nut 14 move in opposite directions simultaneously. The movement of the first lead screw nut 12 and the second lead screw nut 14 in opposite directions drives the first side positioning plate 11 and the second side positioning plate 16 to move in opposite directions. When the first side positioning plate 11 or the second side positioning plate 16 is in contact with one side surface of the thermostat front cover, it can drive the thermostat front cover to move. When both the first side positioning plate 11 and the second side positioning plate 16 are in contact with the other two sides of the thermostat housing, the first side positioning plate 11 and the second side positioning plate 16 center and position the thermostat front cover.

[0028] In one specific embodiment, please refer to Figure 3 Multiple sets of grooves 19 are provided on one side surface of the first side positioning plate 11 and the second side positioning plate 16. Guide rods 18 are rotatably arranged in the grooves 19. After the first side positioning plate 11 and the second side positioning plate 16 position the front cover of the thermostat, the front cover of the thermostat can be automatically centered and positioned. At the same time, it is convenient to unload the thermostat after assembly, and an assembly gap is reserved for the rear cover to facilitate the positioning and installation of the rear cover of the thermostat.

[0029] Furthermore, the ends of the first side positioning plate 11 and the second side positioning plate 16 both extend into the front cover positioning groove 2, which can be used to position and mate the rear cover and the front cover of the thermostat.

[0030] Please see Figure 4 as well as Figure 5 The automatic positioning structure 4 includes an inclined positioning block 41, which is movably disposed in the storage groove 43. The storage groove 43 is symmetrically disposed on the other two sides of the front cover positioning groove 2. A return spring 42 is also disposed in the storage groove 43. One end of the return spring 42 is connected to the inclined positioning block 41. Through the elastic force of the return spring 42, the inclined positioning block 41 is made to fit against the two sides of the front cover of the thermostat, so that the front cover can be automatically positioned.

[0031] When the thermostat front cover is placed in the front cover positioning groove 2, push the thermostat front cover downward. At the same time, the thermostat front cover moves the inclined positioning block 41 in the storage groove 43. The inclined positioning block 41 compresses the return spring 42. When the thermostat front cover is in contact with the bottom of the front cover positioning groove 2, the return spring 42 makes the inclined positioning block 41 fit with the two side surfaces of the thermostat front cover and positions the thermostat front cover.

[0032] Please see Figure 4 as well as Figure 5The assembly table 7 also has a rear positioning structure 3 for longitudinal positioning of the rear cover on one side of its upper surface. The rear positioning structure 3 includes a rear positioning plate 34, which is located on the rear side of the assembly table 7. The assembly table 7 also has a mounting groove 32 on its upper surface. An electric push rod 31 is provided on one side of the mounting groove 32. One end of the piston rod of the electric push rod 31 is connected to a connecting frame 33. The connecting frame 33 is located on one side of the rear positioning plate 34. By setting the rear positioning plate 34, the longitudinal position of the rear cover can be positioned, which facilitates the positioning and assembly of the rear cover and the front cover.

[0033] The electric push rod 31 drives the connecting frame 33 to move. After the connecting frame 33 moves, the positioning plate 34 moves, so that the rear positioning plate 34 moves to the positioning position of the rear cover and the front cover of the thermostat. Then, the rear cover of the thermostat is placed between the first side positioning plate 11 and the second side positioning plate 16, and the rear cover of the thermostat is attached to the rear positioning plate 34, thereby positioning the rear cover of the thermostat and the front cover of the thermostat, and locking and fixing the rear cover of the thermostat and the front cover of the thermostat.

[0034] Please see Figure 4 as well as Figure 5 The bottom of the front cover positioning groove 2 is also provided with a top material structure 5. The top material structure 5 includes two sets of grooves 53. The grooves 53 are symmetrically arranged on both sides of the bottom of the front cover positioning groove 2. Each groove 53 is provided with a pusher plate 54. The two sets of pusher plates 54 are connected by a concave bracket 51. With the setting of the concave bracket 51, the two sets of pusher plates 54 can be lifted without driving them. The middle of the concave bracket 51 is connected to a cylinder 52. One end of the cylinder 52 is connected to the cavity. The cavity is set on one side of the assembly table 7. The assembled temperature controller can be lifted to facilitate unloading.

[0035] After the front cover and rear cover of the thermostat are assembled, the concave bracket 51 is moved by the cylinder 52. The concave bracket 51 simultaneously moves the two sets of push plates 54. The push plates 54 move out of the groove 53 and lift the thermostat. At the same time, the thermostat rotates the guide rod 18 during the lifting process to facilitate the guiding movement of the thermostat. After the thermostat moves out of the front cover positioning groove 2, the thermostat can be taken out.

[0036] In this utility model, both the electric push rod 31 and the cylinder 52 are connected to the control panel 6. The control panel 6 is located on one side of the assembly table 7. The extension and retraction of the electric push rod 31 and the cylinder 52 can be controlled by the corresponding switches on the control panel 6.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
