[0002] A thermostat is a temperature sensing device that automatically opens or closes a circuit to maintain a controlled part within a certain temperature range under normal operation. Thermostat cam riveting is a method of fixing the thermostat cam to the thermostat housing. Riveting is a process of joining two or more metal plates together by using rivets. In the riveting process of the thermostat cam, a special rivet gun is usually used to drive the rivet between the thermostat housing and the cam to fix the cam in place.

[0003] The utility model with announcement number CN205967266U discloses a cam riveting device fixture for thermostat temperature adjustment, including a thermostat shell placement rack, a mounting base and a riveting workbench. The thermostat shell placement rack is arranged on the mounting base, the mounting base is arranged on the riveting workbench, the riveting workbench and the mounting base are connected by a fixing device, and the thermostat shell placement rack is provided with a countersunk hole and two sets of fixing bars.

When the cam plate of the thermostat housing is actually riveted, the sizes and shapes of thermostats of different models may be different. The fixed bars and countersunk holes in the document can only be used to position and clamp the thermostat housing of a fixed model, and the flexibility during use is poor.

[0005] For this purpose, a cam sheet riveting fixture for thermostat temperature adjustment is proposed. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] Reference Figure 1-Figure 4A cam riveting fixture for thermostat temperature adjustment includes a riveting workbench 1 and a clamping mechanism 5. A bottom groove 11 is opened in the middle of the upper surface of the riveting workbench 1, and a lifting mechanism 2 is installed on the inner bottom surface of the bottom groove 11. A clamping platform 3 is installed at one end of the lifting mechanism 2 away from the inner bottom surface of the bottom groove 11. A countersunk hole 33 is opened in the middle of the upper surface of the clamping platform 3. Specifically, when clamping the thermostat shell, the thermostat shell can be placed on the upper surface of the clamping platform 3, and the bottom of the thermostat shell can be placed inside the countersunk hole 33.

[0024] Reference Figure 1-Figure 4 The upper surfaces of both sides of the clamping platform 3 near the countersunk hole 33 are symmetrically provided with slide grooves 34, and the internal cavity at the bottom end of the slide groove 34 is connected to the internal cavity of the clamping platform 3; the clamping mechanism 5 includes a motor 51, which is fixedly connected to the right outer wall of the clamping platform 3, and a screw rod 52 is installed at the output end of the motor 51. The end of the screw rod 52 away from the motor 51 passes through the right side wall of the clamping platform 3 and is rotatably connected to the left inner wall of the clamping platform 3 through a bearing. The outer surface of the screw rod 52 is threadedly connected to two moving blocks 53, and the screw rod 52 has two threaded sections with opposite rotation directions, and the two moving blocks 53 are respectively located on the threaded sections of the screw rod 52 with opposite rotation directions, and the input end of the motor 51 is electrically connected to an external power supply; specifically, starting the motor 51 causes the screw rod 52 to rotate, and the two moving blocks 53 can approach or move away from each other under the rotation of the screw rod 52.

[0025] Reference Figure 1-Figure 4 The end of the moving block 53 away from the screw rod 52 passes through the slide groove 34 and is fixedly connected with the clamping plate 6, and the outer surface of the upper end of the moving block 53 is slidably connected with the inner surface of the slide groove 34; specifically, the moving moving block 53 can drive the two clamping plates 6 to approach or move away from each other, so as to clamp the upper ends of different thermostat shells, so that the riveting machine can complete the riveting work of the cam piece; through the cooperation of the above structure, when the cam piece for thermostat temperature adjustment is riveted, the thermostat shells of different sizes or shapes can be fixedly clamped, thereby improving the flexibility of the cam piece in clamping the thermostat shell during riveting.

[0026] Reference Figure 1-Figure 4 The lifting mechanism 2 includes an electric cylinder 21, which is fixedly connected to the inner bottom surface of the bottom groove 11. A piston rod 22 is installed at the output end of the upper surface of the electric cylinder 21. The end of the piston rod 22 away from the electric cylinder 21 is fixedly connected to the middle of the lower surface of the clamping table 3, and the input end of the electric cylinder 21 is electrically connected to an external power supply. Specifically, when it is necessary to adjust the height of the distance between the clamp and the riveting machine, the electric cylinder 21 can be started to make the piston rod 22 drive the clamping table 3 to move up and down, so that the height between the thermostat housing and the riveting machine can be adjusted.

[0027] Reference Figure 1-Figure 4The upper surfaces of both ends of the riveting workbench 1 are fixedly connected with sliding rods 4, and the upper surfaces of the sliding rods 4 are fixedly connected with anti-slip blocks 41. The lower ends of the outer walls of both sides of the clamping platform 3 are fixedly connected with slide plates 31. The upper surface of the slide plates 31 is provided with sliding holes 32, and the inner surfaces of the sliding holes 32 are slidably connected with the outer surfaces of the sliding rods 4. Specifically, when the clamping platform 3 moves up and down, the clamping platform 3 will also slide on the outer surface of the sliding rod 4 through the sliding holes 32 on the slide plates 31, thereby preventing the clamping platform 3 from deviating during the up and down movement.

[0028] The implementation principle of the cam riveting fixture for thermostat temperature adjustment in the present application is as follows:

[0029] When using the clamp, first connect the external power supply, place the thermostat housing on the upper surface of the clamping table 3, and place it between the two clamping plates 6, and place the bottom of the thermostat housing inside the countersunk hole 33, then start the motor 51 to rotate the screw rod 52, and the two moving blocks 53 can move closer to or away from each other under the rotation of the screw rod 52, and the moving moving blocks 53 can drive the two clamping plates 6 to move closer to or away from each other, so as to clamp the upper ends of different thermostat housings, so that the riveting machine can complete the riveting work of the cam piece; through the cooperation of the above structure, when the cam piece for thermostat temperature adjustment is riveted, thermostat housings of different sizes or shapes can be fixed and clamped, thereby improving the flexibility of clamping the thermostat housing during the cam piece riveting work.

[0030] On the other hand, when the height distance between the clamp and the riveting machine needs to be adjusted, the electric cylinder 21 can be started to make the piston rod 22 drive the clamping table 3 to move up and down, so that the height between the thermostat housing and the riveting machine can be adjusted. When the clamping table 3 moves up and down, the clamping table 3 will also slide on the outer surface of the slide rod 4 through the sliding hole 32 on the slide plate 31, thereby preventing the clamping table 3 from shifting during the up and down movement.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
