Description

Technical Field

[0001] This utility model relates to the field of sensor housing technology, and in particular to a high-efficiency sensor housing production device. Background Technology

[0002] The sensor housing is a key component of the sensor. Its main function is to protect the internal sensitive elements, circuit modules and other core components from the influence of the external environment (such as dust, moisture, vibration, impact, electromagnetic interference, etc.). At the same time, it provides structural support and a mounting base for the sensor. Sensor housing castings are generally manufactured using conventional machining methods, but require specialized four-axis equipment for processing.

[0003] Existing four-axis machining of workpieces using specialized equipment requires special equipment for processing, rotation for positioning, and customization of the specialized equipment. The rotational repeatability positioning accuracy is poor, with an error of 0.05mm, and the processing efficiency is low. Utility Model Content

[0025] Reference Figures 1-6A high-efficiency sensor housing production device includes a workbench 1, a clamping device 2, and a housing body 3. The top of the workbench 1 has two workstations, and the top of several workstations is fixedly equipped with clamping devices 2. The clamping device 2 includes several positioning seats 201, clamping seats 202, and limiting seats 203. The limiting seats 203 and several positioning seats 201 are all fixedly connected to the top of the workbench 1 by bolts. The bottom end of the clamping seat 202 is fixedly connected to one side of the outside of the workbench 1 by bolts. The housing body 3 is located in the middle of the clamping device 2. Both sides of the outer wall of the housing body 3 are attached to one side of several positioning seats 201. The clamping seats 202 and limiting seats 203 are distributed on the other two sides of the outer wall of the housing body 3. The top ends of the clamping seats 202 and limiting seats 203 are threadedly connected with positioning bolts 204. One end of the positioning bolt 204 abuts against the outer wall of the housing body 3. Several support columns 101 are fixedly connected to the top of the workbench 1.

[0026] In use, a series of positioning seats 201, clamping seats 202 and limiting seats 203 form an encircling positioning from the four sides of the outer wall of the main body 3. The positioning bolts 204 are spirally pushed to press against the outer wall of the housing, and together with the support column 101, they support the bottom of the housing to achieve multi-directional rigid fixation. The dual-station design can clamp two housings at the same time. It can adapt to housings of different specifications without the need for customized special fixtures. The multi-directional positioning structure keeps the housing fixed and repeatable positioning accuracy within a certain value, which solves the problem of rotational positioning error of special equipment. The modular design of bolt connection does not require customized special fixtures, reducing equipment adaptation costs. Moreover, the parallel operation of the dual stations improves processing efficiency and breaks through the bottleneck of low processing efficiency.

[0027] In this embodiment, the support column 101 is located in the middle of the clamping device 2, the bottom of the housing body 3 is placed on the top of the support column 101, the top of the workbench 1 is provided with a T-shaped rod 4, and the bottom three ends of the T-shaped rod 4 are fixedly connected with abutment columns 401. The abutment columns 401 abut against the bottom of the inner wall of the housing body 3 and are located on the top of the support column 101. The two sides of the T-shaped rod 4 are respectively attached to the inner wall of the housing body 3 and fixedly connected to the top of the workbench 1 by bolts.

[0028] In use, the T-shaped rod 4 abuts against the support column 101 from the bottom inside the shell through the abutment column 401, and the two sides are attached to the inner wall of the shell to form a double limit inside and outside. Together with the external clamping device 2, it forms a "clipping and supporting" fixing system to eliminate micro-deformation during shell processing. The rigid contact between the abutment column 401 and the support column 101 avoids the shell from deforming due to force, which affects the processing accuracy and improves the product qualification rate. The universal internal support structure does not require customized internal supports for different shells, making it more adaptable.

[0029] In this embodiment, a number of quick connectors 102 are fixedly connected to the bottom of the workbench 1, a frame 5 is provided at the bottom of the workbench 1, a docking seat 501 is fixedly connected to the top of the frame 5, the quick connectors 102 are inserted into the docking seat 501, a crossbeam frame 6 is provided at the top of the workbench 1, a number of drive motors 601 are fixedly connected inside the crossbeam frame 6, a rotating seat 7 is provided at the top of the housing body 3, the shaft of the rotating seat 7 passes through the crossbeam frame 6 and is fixedly connected to the output end of the drive motor 601.

[0030] In use, the quick-connect coupling 102 and the docking seat 501 are fastened together with bolts to achieve precise docking between the workbench 1 and the frame 5. The drive motor 601 drives the spray gun 801 to rotate through the rotatable seat 7. After the main body 3 is processed, the inside is treated with air jet dust removal.

[0031] In this embodiment, as a further solution of the present invention, a mounting bracket 701 is fixedly connected to the bottom of the rotating base 7, and a drive motor 702 is fixedly connected inside the side plate of the mounting bracket 701. Two sets of jet devices 8 are fixedly installed on the surface of the crossbeam frame 6. The jet devices 8 are located directly above the main body 3 of the housing. The jet devices 8 include a spray gun 801, a controller 803, an air pump 804 and a ventilation shell. The spray gun 801 is located between the mounting brackets 701. The two ends of the outer wall of the spray gun 801 are rotatably connected to the mounting bracket 701. The output end of the drive motor 702 is fixedly connected to one end of the outer wall of the spray gun 801. An air supply pipe 802 is fixedly connected to the top of the spray gun 801.

[0032] In use, after the drive motor 702 starts, its output end drives the shaft on the outer wall of the spray gun 801 to rotate, so that the spray gun 801 can adjust the spray angle between the mounting brackets 701. The angle of the spray gun 801 can be flexibly adjusted by the drive motor 702 to adapt to the cleaning needs of different parts of the housing body 3 and avoid cleaning dead corners. The air pump 804 draws in air through the vent shell, filters impurities through the filter element 806, and delivers clean air to the controller 803. The controller 803 adjusts the air pressure and then introduces the gas into the spray gun 801 through the air supply pipe 802. The spray gun 801 sprays air in a directional manner on the surface of the housing body 3 to remove residual dust, debris or impurities on the surface. Two sets of spray devices 8 are symmetrically distributed on the top of the housing body 3, which can cover a wider cleaning range. The filter element 806 pre-treats the air to prevent impurities from contaminating the housing surface with the airflow and ensure cleaning quality.

[0033] In this embodiment, as a further solution of the present invention, the other end of the air supply pipe 802 is fixedly connected to one side of the controller 803. The controller 803, the air pump 804 and the ventilation shell are all fixedly installed on the top of the crossbeam frame 6. The air supply end pipe of the air pump 804 is fixedly connected to one side of the controller 803. The air inlet end pipe of the air pump 804 is integrally connected to the ventilation shell. The top of the ventilation shell is fixedly connected to the filter element 806. The air pump 804 is located between the controller 803 and the outer shell 805. A dust collection box 9 is provided between the two sets of jet devices 8. The dust collection box 9 is fixedly connected to the top of the crossbeam frame 6. The outer wall of the dust collection box 9 is integrally connected to the dust collection pipe 905.

[0034] During use, the dust generated by the jet device 8 during cleaning is drawn into the dust collection box 9 by the fan 901 through the suction pipe 905 and the suction head 906. The dust-laden air first passes through the collection box 904, where larger particles settle due to gravity. The remaining fine dust rises with the airflow and is intercepted and filtered by the filter screen 903. The purified air is discharged from the top air outlet of the dust collection box 9 by the fan 901. The filter frame 902 further prevents dust leakage. The air pump 804, controller 803, and vent shell form a closed-loop air circuit to ensure jet pressure. The dust collection system is linked with the jet device 8 to clean and remove dust simultaneously, maintaining a clean working environment and protecting the health and stability of operators. At the same time, the dust collection system handles dust in real time to avoid secondary pollution.

[0035] In this embodiment, as a further solution of the present invention, the other end of the suction pipe 905 passes through the crossbeam frame 6 and is fixedly connected to the suction head 906. A fan 901 is fixedly installed on the top of the suction box 9. A filter frame 902 is provided outside the fan 901. The filter frame 902 covers the air outlet on the top of the suction box 9 and is fixedly connected by bolts. A filter screen 903 is provided at the bottom of the fan 901. One end of the filter screen 903 passes through one side of the suction box 9 and is fixedly connected by bolts. A collection box 904 is inserted into the opening on one side of the suction box 9. The collection box 904 is located on top of the filter screen 903. A drive cylinder 10 is provided at the bottom of both ends of the crossbeam frame 6. The telescopic end of the drive cylinder 10 is fixedly connected to the top of the crossbeam frame 6.

[0036] In use, the drive cylinder 10 is fixedly mounted on the machine tool. The telescopic end of the drive cylinder 10 drives the crossbeam 6 to rise and fall, adjusting the distance between the jet spray device 8, the suction head 906, and the main body 3. For different sized housings, the height is adjusted to ensure that the spray distance of the spray gun 801 is appropriate and the suction coverage of the suction head 906 is uniform. The drive cylinders 10 at both ends of the crossbeam 6 extend and retract synchronously to ensure overall horizontal lifting and avoid uneven cleaning or dust collection due to tilting. The machine tool uses a handle frame to fix the drive cylinder 10, providing stable support for the entire device.

[0037] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The device adopts a dual-station design. The clamping device 2 on the top of the workbench 1 forms a surrounding positioning from the four sides of the outer wall of the shell body 3. The positioning seat 201, clamping seat 202 and limiting seat 203 cooperate with the positioning bolt 204 to press against the shell. At the same time, the T-shaped rod 4 presses against the support column 101 from the bottom inside through the abutment column 401 to form a "clamping outside and supporting inside" fixing system, which eliminates micro-deformation during processing, avoids shell deformation under force affecting accuracy, and can adapt to shells of different specifications without the need for customized special fixtures. The workbench 1 is quickly plugged into and fixed with the docking seat 501 of the frame 5 through the quick connector 102 to ensure precise docking with the machine tool. The drive motor 601 on the crossbeam frame 6 drives the relevant components to operate through the rotary seat 7. After the shell is processed, the jet device 8 is started to remove dust. The drive motor 702 drives the shaft of the spray gun 801 to rotate, flexibly adjusting the spray angle to adapt to the cleaning needs of different parts of the housing. The air pump 804 draws in air through the vent housing, filters it through the filter element, and the controller 803 adjusts the air pressure. The air is then sent to the spray gun 801 through the air supply pipe 802 to spray air in a directional manner to remove dust and impurities from the housing surface. Two sets of symmetrically distributed spray guns 801 expand the cleaning range and ensure cleaning quality. The dust generated by the air spray cleaning is handled by the dust collection box 9: the fan 901 draws in dust-laden air through the dust collection pipe 905 and the dust collection head 906. Larger particles settle into the collection box 904, while fine dust is intercepted by the filter screen 903. The purified air is discharged through the filter frame 902, achieving a dust-free cleaning environment. Impurities can also be recycled. The drive cylinders 10 at both ends of the crossbeam frame 6 extend and retract synchronously to adjust the height of the spray device 8 and the dust collection head 906 to adapt to different sizes of housings and ensure uniform spray distance and suction coverage. The machine tool is fixed to the drive cylinders 10 by the handle frame, providing stable support. The entire device achieves efficient integrated processing of the shell from fixing, machining to cleaning through modular design and multi-system linkage, which not only ensures machining accuracy but also improves production efficiency. It is highly adaptable and easy to maintain.
