Description

Technical Field

[0001] This utility model relates to the technical field of thermostat housing processing equipment, specifically a deburring device for thermostat housings. Background Technology

[0002] A thermostat is a device for controlling temperature, typically used to regulate the temperature in heating, cooling, and air conditioning systems. The thermostat housing is made of heat-resistant and corrosion-resistant materials, usually metal or hard plastic. During manufacturing, the openings of the thermostat housing are usually deburred.

[0003] Most existing deburring methods rely on manual operation. One hand holds the workpiece, while the other hand holds a handheld electric deburring machine to remove burrs. When operating manually with both hands, the operator must simultaneously position the workpiece and control the equipment. Especially for complex structures such as deep holes and irregular openings, the operator needs to frequently adjust the angle and force of the handheld device, resulting in a long deburring time per cycle. In addition, the existing operating table itself has a simple structure and lacks an integrated dust collection device. Dust generated by metal grinding will be directly emitted into the workshop, affecting the workshop environment. Utility Model Content

[0008] The upper end of the third motor is provided with an annular dust collection box, which is penetrated by the second rotating shaft and the grinding shaft. The annular dust collection box is provided with multiple detachable metal filter cartridges. A transfer pipe is provided on one side of the annular dust collection box. The upper end of the processing table is provided with a negative pressure fan, and the suction end of the negative pressure fan is provided with a duct that communicates with the transfer pipe.

[0009] Furthermore, an improvement of this utility model is that the base is penetrated by the first rotating shaft, and the base is welded to the first rotating shaft.

[0015] The three-way adjustment mechanism enables three-dimensional spatial positioning of the grinding shaft, avoiding frequent manual adjustment of the handheld tool angle, significantly shortening the workpiece positioning time, and reducing the labor intensity of operators.

[0016] The fixed grinding axis design allows operators to focus on workpiece gripping and movement. Combined with the continuous rotation function driven by dual motors, it significantly improves the deburring efficiency of complex structures such as deep holes and irregular openings, meeting the needs of mass production.

[0030] Equipment initialization and parameter adjustment:

[0031] According to the opening size of the thermostat housing and the processing requirements, the operator starts the lifting assembly 7. The lifting assembly 7 can be an electric lifting rod. At this time, the support plate 5 will slide in the slot 6 of the first U-shaped frame 3, thereby synchronously adjusting the overall height of the second U-shaped frame 4 and the grinding shaft 13.

[0032] Start the first motor 2, which drives the first U-shaped frame 3 to rotate through the transmission shaft, so that the third motor 11 and the grinding shaft 13 rotate around the drive shaft axis to complete the horizontal angle positioning;

[0033] Then start the second motor 8, drive the base 10 to drive the third motor 11 to rotate around the axis of the first rotating shaft 9, realize the spatial posture adjustment of the grinding shaft 13, and ensure that the grinding shaft 13 is in the appropriate processing position.

[0034] Deburring operation execution:

[0035] Turn on the negative pressure fan 19, and through the connection between the adapter pipe 18 and the duct, a negative pressure suction field is formed in the conical sleeve 15 area of ​​the annular dust collection box 14.

[0036] The operator holds the thermostat housing workpiece and aligns the opening with the high-speed rotating grinding shaft 13, so that the grinding shaft 13 is inserted into the workpiece. The burr grinding operation is completed by controlling the movement trajectory of the workpiece.
